| 1 | Analysis of in vivo patterns of caspase 3 gene expression in primary hepatocellular carcinoma and its relationship to p21^(WAF1) expression and hepatic apoptosis显示文摘AIM To detect the expression of caspase 3gene in primary human hepatocellular carcinoma(HCC)and investigate its relationship to p21WAF1gene expression and HCC apoptosis.METHODS In situ hybridization was employedto determine caspase 3 and p21WAF1expression inHCC.In situ end-labeling was used to detecthepatocytic apoptosis in HCC.RESULTS Twenty-one of 39(53.8%)cases ofHCC were found to express caspase 3transcripts,while 45.2% of HCC failed toexpress caspase 3.Non-cancerous adjacent livertissues showed more positive caspase 3(87.5%,7/8)as compared with HCC(P<0.05).The expression of caspase 3 is correlated withHCC differentiation,72.2%(13/18)ofmoderately to highly differentiated HCC showedcaspase 3 transcripts positive,while only 38.1%of poorly differentiated HCC harbored caspase 3transcripts(P<0.05).No relationship wasfound between caspase 3 expression and tumorsize or grade or metastasis,although 52.5%(5/8)of HCC with metastasis were caspase 3positive and a little higher than that with nometastasis(51.6%,P>0.05).Expression of caspase 3 alone did not affect the apoptosisindex(AI)of HCC.The AI was 7.12%o in caspase3-positive tumors(n=21),while in caspase 3-negative cases(n=18)6.59%0(P>0.05).Expression of caspase 3 clearly segregated withp21WAF1positive tumors as compared withp21WAF1-negative cases(16 of 23,69.6% versus5 of 16,31.3%)with statistical significance(P=0.017).In the cases with positive caspase 3and negative p21WAF1,the Al was found slightlyhigher,but with no statistical significance,thanthat with expression of p21WAF1and caspase 3(7.21‰ vs 6.98‰,P>0.05).CONCLUSION Loss of caspase 3 expressionmay contribute to HCC carcinogenesis,althoughthe expression of caspase 3 does not correlatewell with cell apoptosis in HCC.p21WAF1may bemerely one of the inhibitors which can reducecaspase 3 mediated cell apoptosis in HCCs. | Bao Hua Sun Jun Zhang Bao JǜWang Xi Ping Zhao You Kun Wang Zhi Qun Yu Dong Liang Yang Lian Jie Hao Department of Clinical Immunology,Tongji Hospital,Tongji Medical University,Wuhan 430030,Hubei Province,China | 2000 | World Journal of Gastroenterology2000,6,3: | 65 |
| 2 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018,63,23: | 54 |

| 4 | A temperature prediction-correction method for estimating surface soil heat flux from soil temperature and moisture data显示文摘Surface soil heat flux is a component of surface energy budget and its estimation is needed in land-atmosphere interaction studies. This paper develops a new simple method to estimate soil heat flux from soil temperature and moisture observations. It gives soil temperature profile with the thermal diffusion equation and, then, adjusts the temperature profile with differences between observed and computed soil temperatures. The soil flux is obtained through integrating the soil temperature profile. Compared with previous methods, the new method does not require accurate thermal conductivity. Case studies based on observations, synthetic data, and sensitivity analyses show that the new method is preferable and the results obtained with it are not sensitive to the availability of temperature data in the topsoil. In addition, we pointed out that the soil heat flux measured with a heat-plate can be quite erroneous in magnitude though its phase is accurate. | Kun Yang JieMin Wang | 2008 | Science China Earth Sciences2008,51,5: | 39 |
| 5 | Present and future of prophylactic antibiotics for severe acute pancreatitis显示文摘AIM: To investigate the role of prophylactic antibiotics in the reduction of mortality of severe acute pancreatitis (SAP) patients, which is highly questioned by more and more randomized controlled trials (RCTs) and metaanalyses. METHODS: An updated meta-analysis was performed. RCTs comparing prophylactic antibiotics for SAP with control or placebo were included for meta-analysis. The mortality outcomes were pooled for estimation, and re-pooled estimation was performed by the sensitivity analysis of an ideal large-scale RCT. RESULTS: Currently available 11 RCTs were included. Subgroup analysis showed that there was significant reduction of mortality rate in the period before 2000, while no significant reduction in the period from 2000 [Risk Ratio, (RR ) = 1.01, P = 0.98]. Funnel plot indi-cated that there might be apparent publication bias in the period before 2000. Sensitivity analysis showed that the RR of mortality rate ranged from 0.77 to 1.00 with a relatively narrow confidence interval (P < 0.05). However, the number needed to treat having a minor lower limit of the range (7-5096 patients) implied that certain SAP patients could still potentially prevent death by antibiotic prophylaxis. CONCLUSION: Current evidences do not support prophylactic antibiotics as a routine treatment for SAP, but the potentially benefited sub-population requires further investigations. | Kun Jiang Wei Huang Xiao-Nan Yang Qing xia | 2012 | World Journal of Gastroenterology2012,18,3: | 37 |
| 6 | Prevalence and evolution of drug resistance HIV-1 variants in Henan, China显示文摘To understand the prevalence and evolution of drug resistant HIV strains in Henan China after the implementation of free antiretroviral therapy for AIDS patients. 45 drug nave AIDS patients, 118 AIDS patients who received three months antiretroviral therapy and 124 AIDS patients who received six months antiretroviral treatment were recruited in the southern part of Henan province. Information on general condition, antiretroviral medicines, adherence and clinical syndromes were collected by face to face interview. Meanwhile, 14ml EDTA anticoagulant blood was drawn. CD4/CD8 T cell count, viral load and genotypic drug resistance were tested. The rates of clinical improvement were 55.1% and 50.8% respectively three months and six months after antiretroviral therapy. The mean CD4 cell count after antiretroviral therapy was significantly higher than in drug nave patients. The prevalence rate of drug resistant HIV strains were 13. 9%, 45.4% and 62.7% in drug nave patients, three month treatment patients and six month treatment patients, respectively. The number of resistance mutation codons and the frequency of mutations increased significantly with continued antiretroviral therapy. The mutation sites were primarily at the 103, 106 and 215 codons in the three-month treatment group and they increased to 15 codon mutations in the six-month treatment group. From this result, the evolution of drug resistant strains was inferred to begin with the high level NNRTI resistant strain, and then develop low level resistant strains to NRTIs. The HIV strains with high level resistance to NVP and low level resistance to AZT and DDI were highly prevalent because of the AZT+DDI+NVP combination therapy. These HIV strains were also cross resistant to DLV, EFV, DDC and D4T. Poor adherence to therapy was believed to be the main reason for the emergence and prevalence of drug resistant HIV strains. The prevalence of drug resistant HIV strains was increased with the continu- ation of antiretroviral therapy in the southern part of Henan province. Measures, that could promote high level adherence, provide new drugs and change ART regimens in failing patients, should be implemented as soon as possible. | Jing Yun LI Han Ping LI Lin LI Hong LI Zhe WANG Kun YANG Zuo Yi BAO Dao Min ZHUANG Si Yang LIU Yong Jian LIU Hui XING Yi Ming SHAO | 2005 | Cell Research2005,15,11: | 34 |

| 8 | Effectiveness and safety of splenectomy for gastric carcinoma:A meta-analysis显示文摘AIM:To evaluate the impact of splenectomy on longterm survival,postoperative morbidity and mortality of patients with gastric cancer by performing a metaanalysis.METHODS:A search of electronic databases to identify randomized controlled trials in The Cochrane Library trials register,Medline,CBMdisc(Chinese Biomedical Database) and J-STAGE,etc was performed.Data was extracted from the studies by 2 independent reviewers.Outcome measures were survival,postoperative morbidity and mortality and operation-related events.The meta-analyses were performed by RevMan 4.3.RESULTS:Three studies comprising 466 patients were available for analysis,with 231 patients treated by gastrectomy plus splenectomy.Splenectomy could not increase the 5-year overall survival rate [RR = 1.17,95% confidence interval(CI) 0.97-1.41].The postoperative morbidity(RR = 1.76,95% CI 0.82-3.80) or mortality(RR = 1.58,95% CI 0.45-5.50) did not suggest any significant differences between the 2 groups.No significant differences were noted in terms of number of harvested lymph nodes,operation time,length of hospital stay and reoperation rate.Subgroup analyses showed splenectomy did not increase the survival rate for proximal and whole gastric cancer.No obvious differences were observed between the 2 groups when stratified by stage.Sensitivity analyses indicated no significant differences regarding the survival rates(P > 0.05) .CONCLUSION:Splenectomy did not show a beneficial effect on survival rates compared to splenic preservation.Routinely performing splenectomy should not be recommended. | Kun Yang Xin-Zu Chen Jian-Kun Hu Bo Zhang Zhi-Xin Chen Jia-Ping Chen | 2009 | World Journal of Gastroenterology2009,15,42: | 33 |
| 9 | Parameterizing soil organic carbon's impacts on soil porosity and thermal parameters for Eastern Tibet grasslands显示文摘This study investigates the stratification of soil thermal properties induced by soil organic carbon (SOC) and its impacts on the parameterization of the thermal properties. Soil parameters were measured for alpine grassland stations and North China flux stations, with a total of 34 stations and 77 soil profiles. Measured data indicate that the topsoils of alpine grasslands contain high SOC contents than underlying soil layers, which leads to higher soil porosity values and lower thermal conductivity and bulk density values in the topsoils. However, this stratification is not evident at the lowland stations due to low SOC contents. Evaluations against measured data show that three thermal conductivity schemes used in land surface models severely overestimate the values for soils with high SOC content (i.e. topsoils of alpine grassland), but they are better for soils with low SOC content. A new parameterization is then developed to take the impacts of SOC into account. The new one can well estimate the soil thermal conductivity values in both low and high SOC content cases, and therefore, it is a potential candidate of thermal conductivity scheme to be used in land surface models. | CHEN YingYing YANG Kun TANG WenJun QIN Jun ZHAO Long | 2012 | Science China Earth Sciences2012,55,6: | 31 |
| 10 | Intelligent and connected vehicles: Current status and future perspectives显示文摘Intelligent connected vehicles(ICVs) are believed to change people's life in the near future by making the transportation safer,cleaner and more comfortable. Although many prototypes of ICVs have been developed to prove the concept of autonomous driving and the feasibility of improving traffic efficiency, there still exists a significant gap before achieving mass production of high-level ICVs. The objective of this study is to present an overview of both the state of the art and future perspectives of key technologies that are needed for future ICVs. It is a challenging task to review all related works and predict their future perspectives, especially for such a complex and interdisciplinary area of research. This article is organized to overview the ICV key technologies by answering three questions: what are the milestones in the history of ICVs; what are the electronic components needed for building an ICV platform; and what are the essential algorithms to enable intelligent driving? To answer the first question, the article has reviewed the history and the development milestones of ICVs. For the second question, the recent technology advances in electrical/electronic architecture, sensors, and actuators are presented. For the third question, the article focuses on the algorithms in decision making, as the perception and control algorithm are covered in the development of sensors and actuators. To achieve correct decision-making, there exist two different approaches: the principle-based approach and data-driven approach. The advantages and limitations of both approaches are explained and analyzed. Currently automotive engineers are concerned more with the vehicle platform technology, whereas the academic researchers prefer to focus on theoretical algorithms. However, only by incorporating elements from both worlds can we accelerate the production of high-level ICVs. | YANG DianGe JIANG Kun ZHAO Ding YU ChunLei CAO Zhong XIE ShiChao XIAO ZhongYang JIAO XinYu WANG SiJia ZHANG Kai | 2018 | Science China(Technological Sciences)2018,61,10: | 31 |
| 11 | Treatment efficacy of radiof requency ablation of 338 patients with hepatic malignant tumor and the relevant complications显示文摘AIM: To investigate the treatment efficacy of radiofrequency ablation (RFA) of hepatic malignant tumor and the relevant complications.METHODS: A total of 338 patients with 763 hepatic tumors underwent ultrasound-guided RFA (565 procedures).There were 204 cases of hepatic cellular carcinoma (HCC)with 430 tumors, the mean largest diameter was 4.0 cm.Of them, 48 patients (23.5%) were in stages Ⅰ-Ⅱ (UICC Systems) and 156 (76.5%) in stages Ⅲ-Ⅳ There were 134 cases of metastatic liver carcinoma (MLC), with 333metastases in the liver, the mean diameter was 4.1 cm,the liver metastases of 96 patients (71.6%) came from gastrointestinal tract. Ninety-three percent of the 338patients were treated using the relatively standard protocol. Crucial attention must be paid to monitor the abnormal changes in ultrasound images as well as the vital signs of the patients to find the possible hemorrhage and peripheral structures injury in time. The tumors were considered as ablated completely, if no viability was found on enhanced CT within 24 h or at 1 mo after RFA. These patients were followed up for 3-57 mo.RESULTS: The ablation success rate was 93.3% (401/430tumors) for HCC and was 96.7% (322/333 tumors) for MLC. The local recurrence rate for HCC and MLC was 7.9% (34/430 tumors) and 10.5% (35/333 tumors),respectively. A total of 137 patients (40.5%) underwent 2-11times of repeated ablations because of tumor recurrence or metastasis. The 1st, 2nd, and 3rd year survival rate was84.6%, 66.6%, and 63.1%, respectively;the survival rate from 48 patients of Ⅰ-Ⅱ stage HCC was 93.7%, 80.4%,and 80.4%, respectively. The major complication rate in this study was 2.5% (14 of 565 procedures), which consisted of 5 hemorrhages, 1 colon perforation, 5 injuries of adjacent structures, 2 bile leakages, and 1 skin burn.CONCLUSION: RFA, as a minimally invasive local treatment,has become an effective and relatively safe alternative for the patients of hepatic malignant tumor, even of advanced liver tumor, tumor recurrence, and liver metastases. Knowledge about possible complications and their control may increase the treatment efficacy and help to promote the use of RFA technique. | Min-Hua Chen Wei Yang Kun Yan Wen Gao Ying Dai Yan-Bin Wang Xiao-Peng Zhang Shan-Shan Yin | 2005 | World Journal of Gastroenterology2005,11,40: | 25 |

| 13 | Surveillance-based evidence:elimination of schistosomiasis as a public health problem in the Peoples’Republic of China显示文摘Background:A steady progress on schistosomiasis control in the Peoples’Republic of China(P.R.China)was achieved and broadened into the twelve-year medium and long term national plan(MLNP)which marled the implementation of an integrated control strategy across all endemic areas in P.R.China in 2004.To understand the endemic trends of schistosomiasis to assess the effectiveness of an integrated strategy,we conducted an analysis of schistosomiasis surveillance data spanned from 2005 to 2015.Methods:The schistosomiasis sentinel surveillance data from sentinel sites were collected and analyzed from 2005 to 2015.In these sentinel sites,residents aged 6 years or above were screened annually by indirect hemagglutination assay(IHA),while only antibody positives were followed by stool examination either Kato-katz method(KK)and/or hatching technique(HT).Domestic animals raised in sentinel sites were examined by HT for confirming the infection of schistosomes.Snail investigation was conducted each year through systematic sampling method combined with environmental sampling method.The snails collected from field were tested by microscopic dissection method.The infection rates of schistosomes in residents,domestic animals and snails,as well as the indicators reflecting the snails’distribution were calculated and analyzed.ANOVA analysis was used to examine the changes of the number of eggs per gram feces in population and Chi-square test was used to examine any change in proportions among groups.Results:A total of 148902 residents from sentinel sites attended this study and 631676 blood samples were examined by IHA test during the 11 covered years.The annual average antibody positive rates presented a significant decrease trends,from 17.48%(95%CI:17.20–17.75%)in 2005 to 5.93%(95%CI:5.71–6.15%)(χ2=8890.47,P<0.001)in 2015.During 2005–2015,the average infection rate of schistosomes in residents declined from 2.07%(95%CI:1.96–2.17%)to 0.13%(95%CI:0.09–0.16%),accompanied by significant decrease of infection intensity in population.In 2015,the stool positives were only found in farmers,fishermen and boatmen with infection rate of 0.16%(95%CI:0.11–0.20%),0.17%(95%CI:0–0.50%)respectively.The infection rate of schistosomes in domestic animals dropped from 9.42%(538/5711,95%CI:8.66–10.18%)to 0.08%(2/2360,95%CI:0–0.20%)from 2005 to 2015.Infections were found in eight species of domestic animals at the beginning of surveillance while only two cattle were infected in 2015.Totally 98 ha of new snail habitats were found,while 94.90%(93/98)distributed in lake and marshland regions.The percentage of frames with snails decreased from 16.96%(56884/335391,95%CI:16.83–17.09%)in 2005 to 4.28%(18121/423755,95%CI:4.22–4.34%)in 2014,with a slightly increase in 2015.Meanwhile,the infection rate of schistosomes in snails was decreased from 0.26%(663/256531,95%CI:0.24–0.28%)to zero during 2005–2015.Conclusions:The infection rate of schistosomes declined significantly,providing evidence that the goal of the MLNP was achieved.Elimination of schistosomiasis as a public health problem defined as WHO was also reached in P.R.China nationwide.Surveillance-response system should be improved and strengthened to realize the final goal of schistosomiasis elimination. | Jing Xu Shi-Zhu Li Li-Juan Zhang Robert Bergquist Hui Dang Qiang Wang Shan Lv Tian-Ping Wang Dan-Dan Lin Jian-Bing Liu Guang-Hui Ren Kun Yang Yang Liu Yi Dong Shi-Qing Zhang Xiao-Nong Zhou | 2020 | Infectious Diseases of Poverty2020,9,3: | 20 |
| 14 | Ten-year survival of hepatocellular carcinoma patients undergoing radiofrequency ablation as a first-line treatment显示文摘AIM: To investigate the long-term survival and prognostic factors in hepatocellular carcinoma(HCC) patients undergoing radiofrequency ablation(RFA) as a first-line treatment.METHODS: From 2000 to 2013, 316 consecutivepatients with 404 HCC(1.0-5.0 cm; mean: 3.2 ± 1.1 cm) underwent ultrasonography-guided percutaneous RFA as a first-line treatment. There were 250 males and 66 females with an average age of 60.1 ± 10.8 years(24-87 years). Patients were followed for 1 year to > 10 years after RFA(234, 181, 136, and 71 for 3, 5, 7, and 10 years, respectively). Overall local response rates and long-term survival rates were assessed. Survival results were generated using Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression model. RESULTS: In total, 548 RFA sessions were performed and major complications occurred in 10 sessions(1.8%). Local tumor progression and/or new tumor development were observed in 43.3%(132/305) of the patients during the follow-up period. Overall 5-and 10-year survival rates were 49.7% and 28.4%, respectively. Based on multivariate analysis, three factors were identified as independent prognostic factors for overall survival: Child-Pugh classification(HR = 4.054, P < 0.001), portal vein hypertension(HR = 2.743, P = 0.002), and tumor number(HR = 2.693, P = 0.003). The local progression-free 5- and 10-year survival rates were 42.7% and 19.5%. In addition to the Child-Pugh classification and the number of tumors, the number of RFA sessions(HR = 1.550, P = 0.002) was associated with local progression-free survival.CONCLUSION: RFA can achieve acceptable outcomes for HCC patients as a first-line treatment, especially for patients with Child-Pugh class A, patients with a single tumor and patients without portal vein hypertension. | Wei Yang Kun Yan S Nahum Goldberg Muneeb Ahmed Jung-Chieh Lee Wei Wu Zhong-Yi Zhang Song Wang Min-Hua Chen | 2016 | World Journal of Gastroenterology2016,22,10: | 20 |
| 15 | Large Scale Photochemical Synthesis of M@TiO_(2) Nanocomposites (M = Ag, Pd, Au, Pt) and Their Optical Properties, CO Oxidation Performance, and Antibacterial Effect显示文摘Well-dispersed M@TiO_(2)(M=Ag,Pd,Au,Pt)nanocomposite particles with a diameter of 200-400 nm can be synthesized on a large scale by a clean photochemical route which does not require any additives using spherical rutile nanoparticles as a support.The sizes of Pt,Au,and Pd nanoparticles formed on the surface of TiO_(2) particles are about 1 nm,5 nm,and 5 nm,respectively,and the diameter of Ag nanoparticles is in the range 2-20 nm.Moreover,the noble metal nanoparticles have good dispersity on the particles of the TiO_(2) support,resulting in excellent catalytic activities.Complete conversion in catalytic CO oxidation is reached at temperatures as low as 333 and 363 K,respectively,for Pt@TiO_(2) and Pd@TiO_(2) catalysts.In addition,the antibacterial effects of the as-synthesized TiO_(2) nanoparticles,silver nanoparticles,and Au@TiO_(2) and Ag@TiO_(2) nanocomposites have been tested against Gram-negative Escherichia coli(E.coli)bacteria.The results demonstrate that the presence of the TiO_(2) matrix enhances the antibacterial effect of silver nanoparticles,and the growth of E.coli can be completely inhibited even if the concentration of Ag in Ag@TiO_(2) nanocomposite is very low(10μg/mL). | Shao Feng Chen Jian Ping Li Kun Qian Wei Ping Xu Yang Lu Wei Xin Huang Shu Hong Yu | 2010 | Nano Research2010,3,4: | 20 |
| 16 | Lung transplantation as therapeutic option in acute respiratory distress syndrome for coronavirus disease 2019-related pulmonary fibrosis显示文摘Background:Critical patients with the coronavirus disease 2019(COVID-19),even those whose nucleic acid test results had turned negative and those receiving maximal medical support,have been noted to progress to irreversible fatal respiratory failure.Lung transplantation(LT)as the sole therapy for end-stage pulmonary fibrosis related to acute respiratory distress syndrome has been considered as the ultimate rescue therapy for these patients.Methods:From February 10 to March 10,2020,three male patients were urgently assessed and listed for transplantation.After conducting a full ethical review and after obtaining assent from the family of the patients,we performed three LT procedures for COVID-19 patients with illness durations of more than one month and extremely high sequential organ failure assessment scores.Results:Two of the three recipients survived post-LT and started participating in a rehabilitation program.Pearls of the LT team collaboration and perioperative logistics were summarized and continually improved.The pathological results of the explanted lungs were concordant with the critical clinical manifestation,and provided insight towards better understanding of the disease.Government health affair systems,virology detection tools,and modern communication technology all play key roles towards the survival of the patients and their rehabilitation.Conclusions:LT can be performed in end-stage patients with respiratory failure due to COVID-19-related pulmonary fibrosis.If confirmed positive-turned-negative virology status without organ dysfunction that could contraindicate LT,LT provided the final option for these patients to avoid certain death,with proper protection of transplant surgeons and medical staffs.By ensuring instant seamless care for both patients and medical teams,the goal of reducing the mortality rate and salvaging the lives of patients with COVID-19 can be attained. | Jing-Yu Chen Kun Qiao Feng Liu Bo Wu Xin Xu Guo-Qing Jiao Rong-Guo Lu Hui-Xing Li Jin Zhao Jian Huang Yi Yang Xiao-Jie Lu Jia-Shu Li Shu-Yun Jiang Da-Peng Wang Chun-Xiao Hu Gui-Long Wang Dong-Xiao Huang Guo-Hui Jiao Dong Wei Shu-Gao Ye Jian-An Huang Li Zhou Xiao-Qin Zhang Jian-Xing He | 2020 | Chinese Medical Journal2020,,12: | 19 |
| 17 | Temporal and spatial changes in nutrients and chlorophyll-a in a shallow lake,Lake Chaohu, China: An 11-year investigation显示文摘Temporal and spatial changes of total nitrogen(TN),total phosphorus(TP) and chlorophyll-a(Chl-a) in a shallow lake,Lake Chaohu,China,were investigated using monthly monitoring data from 2001 through 2011.The results showed that the annual mean concentration ranges of TN,TP,and Chl-a were 0.08-14.60 mg/L,0.02-1.08 mg/L,and 0.10-465.90 μg/L,respectively.Our data showed that Lake Chaohu was highly eutrophic and that water quality showed no substantial improvement during 2001 through 2011.The mean concentrations of TP,TN and Chl-a in the western lake were significantly higher than in the eastern lake,which indicates a spatial distribution of the three water parameters.The annual mean ratio of TN:TP by weight ranged from 10 to 20,indicating that phosphorus was the limiting nutrient in this lake.A similar seasonality variation for TP and Chl-a was observed.Riverine TP and NH4+ loading from eight major tributaries were in the range of 1.56 × 104-5.47 × 104 and 0.19 × 104-0.51 × 104 tons/yr over 2002-2011,respectively,and exceeded the water environmental capability of the two nutrients in the lake by a factor of 3-6.Thus reduction of nutrient loading in the sub-watershed and tributaries would be essential for the restoration of Lake Chaohu. | Libiao Yang Kun Lei Wei Meng Guo Fu Weijin Yan | 2013 | Journal of Environmental Sciences2013,25,6: | 19 |
| 18 | Increased brachial-ankle pulse wave velocity is associated with impaired endothelial function in patients with coronary artery disease显示文摘Background Pulse wave velocity and flow-mediated vasodilation (FMD) are widely used as noninvasive modalities for evaluating atherosclerosis. However, it is not known whether pulse wave velocity is related to FMD in patients with coronary artery disease (CAD). Therefore, the present study was designed to investigate the alteration in brachial-ankle pulse wave velocity (baPWV) and endothelial function in CAD patients. Methods Thirty-three patients with CAD and thirty control subjects were recruited for this study. baPWV was measured non-invasively using a VP 1000 automated PWV/ABI analyzer (PWV/ABI, Colin Co. Ltd., Komaki, Japan). Endothelial function as reflected by FMD in the brachial artery was assessed with a high-resolution ultrasound device. Results baPWV was increased in CAD patients compared with control subjects [(1756.1±253.1) cm/s vs (1495.3±202.3) cm/s, P<0.01]. FMD was significantly reduced in CAD patients compared with control subjects [(5.2±2.1) % vs (11.1±4.4) %, P<0.01]. baPWV correlated with FMD (r =-0.68, P<0.001). The endothelium-independent vasodilation induced by sublingual nitroglycerin in the brachial artery was similar in the CAD group compared with the control group. Conclusions CAD is associated with increased baPWV and endothelial dysfunction. Increased baPWV parallels diminished endothelial function. Our data therefore suggest that baPWV can be used as a noninvasive surrogate index in clinical evaluation of endothelial function. | LIU Dong-hong WANG Yan LIAO Xin-xue XU Ming-guo WANG Jie-mei YANG Zhen CHEN Long LU Ming-de LU Kun TAO Jun | 2006 | Chinese Medical Journal2006,,22: | 17 |
| 19 | Adjuvant percutaneous radiofrequency ablation of feeding artery of hepatocellular carcinoma before treatment显示文摘AIM:To evaluate the feasibility and efficacy of percutaneous radiofrequency ablation(RFA) of the feeding artery of hepatocellular carcinoma(HCC) in reducing the blood-flow-induced heat-sink effect of RFA.METHODS:A total of 154 HCC patients with 177 pathologically confirmed hypervascular lesions participated in the study and were randomly assigned into two groups.Seventy-one patients with 75 HCCs(average tumor size,4.3 ± 1.1 cm) were included in group A,in which the feeding artery of HCC was identified by color Doppler flow imaging,and were ablated with multiple small overlapping RFA foci [percutaneous ablation of feeding artery(PAA)] before routine RFA treatment of the tumor.Eighty-three patients with 102 HCC(average tumor size,4.1 ± 1.0 cm) were included in group B,in which the tumors were treated routinely with RFA.Contrast-enhanced computed tomography was used as post-RFA imaging,when patients were followed-up for 1,3 and 6 mo.RESULTS:In group A,feeding arteries were blocked in 66(88%) HCC lesions,and the size of arteries decreased in nine(12%).The average number of punctures per HCC was 2.76 ± 1.12 in group A,and 3.36 ± 1.60 in group B(P = 0.01).The tumor necrosis rate at 1 mo post-RFA was 90.67%(68/75 lesions) in group A and 90.20%(92/102 lesions) in group B.HCC recur-rence rate at 6 mo post-RFA was 17.33%(13/75) in group A and 31.37%(32/102) in group B(P = 0.04).CONCLUSION:PAA blocked effectively the feeding artery of HCC.Combination of PAA and RFA significantly decreased post-RFA recurrence and provided an alternative treatment for hypervascular HCC. | Yi-Bin Hou Min-Hua Chen Kun Yan Jin-Yu Wu Wei Yang | 2009 | World Journal of Gastroenterology2009,15,21: | 17 |
