2Traditional herbal medicine in preventing recurrence after resection of small hepatocellular carcinoma: a multicenter randomized controlled trial显示文摘BACKGROUND: Disease recurrence is a main challenge in treatment of hepatocellular carcinoma (HCC). There is no generally accepted method for preventing recurrence of HCC after resection. OBJECTIVE: To compare the efficacy of a traditional herbal medicine (THM) regimen and transarterial chemoembolization (TACE) in preventing recurrence in post-resection patients with small HCC. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS: This is a multicenter, open-label, randomized, controlled study, which was undertaken in five centers of China. A total of 379 patients who met the eligibility criteria and underwent randomization were enrolled in this trial. One hundred and eighty-eight patients were assigned to the THM group and received Cinobufacini injection and Jiedu Granule, and the other 191 patients were assigned to the TACE group and received one single course of TACE. MAIN OUTCOME MEASURES: Primary outcome measures were the annual recurrence rate and the time to recurrence. Incidence of adverse events was regarded as the secondary outcome measure. RESULTS: Among the 364 patients who were included in the intention-to-treat analysis, 67 patients of the THM group and 87 of the TACE group had recurrence, with a hazard ratio of 0.695 (P = 0.048). Median recurrence-free survival of the patients in the THM and TACE groups was 46.89 and 34.49 months, respectively. Recurrence rates at 1, 2 and 3 years were 17.7%, 33.0% and 43.5% for the THM group, and 28.8%, 42.5% and 54.0% for the TACE group, respectively (P = 0.026). Multivariate analysis indicated that the THM regimen had a big advantage for prolonging the recurrence-free survival. Adverse events were mild and abnormality of laboratory indices of the two groups were similar. CONCLUSION: In comparison with TACE therapy, the THM regimen was associated with diminished risk of recurrence of small-sized HCC after resection, with comparable adverse events. TRIAL REGISTRTION IDENTIFIER: This trial was registered in the Chinese Clinical Trial Registry with the identifier ChiCTR-TRC-07000033.Xiao-feng Zhai Zhe Chen Bai Li Feng Shen Jia Fan Wei-ping Zhou Yun-ke Yang Jing Xu Xiao Qin Le-qun Li Chang-quan Ling 2013Journal of Integrative Medicine2013,11,2:49

4Current Trends of the Prevalence of Childhood Asthma in Three Chinese Cities: A Multicenter Epidemiological Survey显示文摘Objective To analyze the prevalence of asthma and asthma related symptoms among children aged 0-14 years in three Chinese cities and to obtain a crude estimation of the trend of childhood asthma prevalence in China. Methods A cross-sectional, population-based survey of prevalence of asthma was conducted in children aged from 0 to 14 years in 3 major cities of China (Beijing, Chongqing, and Guangzhou) with different geographic locations. All the subjects were randomly selected by a multi-stage sampling method. Three to five schools and kindergartens in 2 urban districts in each city were randomly selected for the survey, and a validated questionnaire that included the core questions of the International Study of Asthma and Allergies in Childhood, Phase Ⅲ questionnaire and several additional questions were used. All questionnaires were completed by parents or guardians of the selected children. Children whose parents responded affirmatively to the question' Has your child ever been diagnosed as asthma by a doctor' were recognized as victims of asthma. Results The prevalence of asthma in Beijing, Chongqing, and Guangzhou was 3.15%, 7.45%, and 2.09%, respectively. These values were significantly higher than those obtained 10 years ago in the national epidemiological survey in 2000 which used the same method of investigation and the same diagnotic criteria (χ2 =3.938, P=0.047; χ2 =73.506, P≤0.001; χ2 =11.956, P=0.001, in each city). Of the asthmatic children 57.21%, 69.91%, and 60.00% had their first attack before the age of 3 in Beijing, Chongqing, and Guangzhou, respectively. Wheezing was the primary clinical manifestation for all asthmatic children , followed by persistent cough and repeated respiratory infections. Both the prevalence of asthma and asthma-related symptoms were statistically higher in males than in females. Conclusion The prevalence of childhood asthma is statistically higher than that 10 years ago in the three Chinese cities.JUAN BAI JiNG ZHAO KUN-LING SHEN LI XIANG AI-HUAN CHEN SUI HUANG YING HUANG JIAN-SHENG WANG RONG-WEI YE 2010Biomedical and Environmental Sciences2010,23,6:37

10Long-term rice-rice-green manure rotation changing the microbial communities in typical red paddy soil in South China显示文摘On the basis of a long-term(30 years) field experiment that involved four rotation systems, rice-rice-winter fallow(RRF), rice-rice-ryegrass(RRG), rice-rice-rape(RRP), and rice-rice-milk vetch(RRV), this study described the effects of green manure on the microbial communities in the red paddy soils using 454 pyrosequencing for the 16 S r RNA gene. The Chao1 richness and non-parametric Shannon's index increased in all soil samples that received green manure treatments. The communities' structures with the green manure applications were significantly dissimilar from that under the winter fallow. Using Metastats tests, many genera in the RRG, RRP and RRV soils were significantly different from those in the RRF soil, including a number of genera that functioned in the nitrogen and sulfur cycles. Analyses of the genera with these functions revealed the shifts in microbial ecosystem functions after long-term green manuring. Changes in the microbial communities increased the ammonium supply and decreased the soil acidification in green-manure-amended soils. Together, these data suggested powerful effects of green manure on both the microbial communities and the biogeochemical cycle driven by the shifts in bacterial functional groups.GAO Song-juan ZHANG Ren-gang CAO Wei-dong FAN Yuan-yuan GAO Ju-sheng HUANG Jing BAI Jin-shun ZENG Nao-hua CHANG Dan-na Shimizu Katsu-yoshi Kristian Thorup-Kristensen 2015Journal of Integrative Agriculture2015,14,12:25
11Shunting branch of portal vein and stent position predict survival after transjugular intrahepatic portosystemic shunt显示文摘AIM:To evaluate the effect of the shunting branch of the portal vein(PV)(left or right)and the initial stent position(optimal or suboptimal)of a transjugular intrahepatic portosystemic shunt(TIPS).METHODS:We retrospectively reviewed 307 consecu5tive cirrhotic patients who underwent TIPS placement for variceal bleeding from March 2001 to July 2010 at our center.The left PV was used in 221 patients and the right PV in the remaining 86 patients.And,224 and83 patients have optimal stent position and sub-optimal stent positions,respectively.The patients were followed until October 2011 or their death.Hepatic encephalopathy,shunt dysfunction,and survival were evaluated as outcomes.The difference between the groups was compared by Kaplan-Meier analysis.A Cox regression model was employed to evaluate the predictors.RESULTS:Among the patients who underwent TIPS to the left PV,the risk of hepatic encephalopathy(P=0.002)and mortality were lower(P<0.001)compared to those to the right PV.Patients who underwent TIPS with optimal initial stent position had a higher primary patency(P<0.001)and better survival(P=0.006)than those with suboptimal initial stent position.The shunting branch of the portal vein and the initial stent position were independent predictors of hepatic encephalopathy and shunt dysfunction after TIPS,respectively.And,both were independent predictors of survival.CONCLUSION:TIPS placed to the left portal vein with optimal stent position may reduce the risk of hepatic encephalopathy and improve the primary patency rates,thereby prolonging survival.Ming Bai Chuang-Ye He Xing-Shun Qi Zhan-Xin Yin Jian-Hong Wang Wen-Gang Guo Jing Niu Jie-Lai Xia Zhuo-Li Zhang Andrew C Larson Kai-Chun Wu Dai-Ming Fan Guo-Hong Han 2014World Journal of Gastroenterology2014,20,3:26
12Analysis on Changes of Basic Climatic Elements and Extreme Events in Xinjiang, China during 1961-2010显示文摘By using the observation data from 89 weather stations in Xinjiang during 1961-2010, this paper analyzed the basic climatic elements including temperature, precipitation, wind speed, sunshine duration, water vapor pressure, and dust storm in the entire Xinjiang and the subareas: North Xinjiang, Tianshan Mountains, and South Xinjiang. The results indicate that from 1961 to 2010 the annual and seasonal mean temperatures in the entire Xinjiang show an increasing trend with the increasing rate rising from south to north. The increasing rate of annual mean minimum temperature is over twice more than that of the annual mean maximum temperature, contributing much to the increase in the annual averages. The magnitude of the decrease rate of low-temperature days is larger than the increase rate of high-temperature days. The increase of warm days and warm nights and the decrease of cold days and cold nights further reveal that the temperature increasing in Xinjiang is higher. In addition, annual and seasonal rainfalls have been increasing. South Xinjiang experiences higher increase in rainfall amounts than North Xinjiang and Tianshan Mountains. Annual rainy days, longest consecutive rainy days, the daily maximum precipitation and extreme precipitation events, annual torrential rain days and amount, annual blizzard days and amount, all show an increasing trend, corresponding to the increasing in annual mean water vapor pressure. This result shows that the humidity has increased with temperature increasing in the past 50 years. The decrease in annual mean wind speed and gale days lessen the impact of dust storm, sandstorm, and floating dust events. The increase in annual rainy days is the cause of the decrease in annual sunshine duration, while the increase in spring sunshine duration corresponds with the decrease in dust weather. Therefore, the increase in precipitation indicators, the decrease in gales and dust weather, and the increasing in sunshine duration in spring will be beneficial to crops growth.JIANG Yuan-An CHEN Ying ZHAO Yi-Zhou CHEN Peng-Xiang YU Xing-Jie FAN Jing BAI Su-Qin 2013Advances in Climate Change Research2013,4,1:22

14Intracoronary arterial retrograde thrombolysis with percutaneous coronary intervention: a novel use of thrombolytic to treat acute ST-segment elevation myocardial infarction显示文摘Background Clearance of coronary arterial thrombosis is necessary in patients with acute ST-segment elevation myocardial infarction (STEMI) undergoing urgent percutaneous coronary intervention (PCI). There is currently no highly-recommended method of thrombus removal during interventional procedures. We describe a new method for opening culprit vessels to treat STEMI: intracoronary arterial retrograde thrombolysis (ICART) with PCI. Methods & Results Eight patients underwent ICART. The guidewire was advanced to the distal coronary artery through the occlusion lesion. Then, we inserted a microcatheter into the distal end of the occluded coronary artery over the guidewire. Urokinase (5–10 wu) mixed with contrast agents was slowly injected into the occluded section of the coronary artery through the microcatheter. The intracoronary thrombus gradually dissolved in 3–17 min, and the effect of thrombolysis was visible in real time. Stents were then implanted according to the characteristics of the recanalized culprit lesion to achieve full revascularization. One patient experienced premature ventricular contraction during vascular revascularization, and no malignant arrhythmias were seen in any patient. No reflow or slow flow was not observed post PCI. Thrombolysis in myocardial infarction flow grade and myocardial blush grade post-primary PCI was 3 in all eight patients. No patients experienced bleeding or stroke. Conclusions ICART was accurate and effective for treating intracoronary thrombi in patients with STEMI in this preliminary study. ICART was an effective, feasible, and simple approach to the management of STEMI, and no intraprocedural complications occurred in any of the patients. ICART may be a breakthrough in the treatment of acute STEMI.Jin-Wen TIAN Mei ZHU Feng-Qi WANG Ke LI Chao-Fei ZHOU Bo LI Min WANG Jue-Lin DENG Bo JIANG Jing BAI Yi GUO Rong-Jie JIN Zhao ZHANG Ying LIN Ji-Hang WANG Shi-Hao ZHAO Ming-Zhi SHEN 2019Journal of Geriatric Cardiology2019,16,6:22

16Effects of long-term green manure application on the content and structure of dissolved organic matter in red paddy soil显示文摘Dissolved organic matter(DOM) plays important roles in soil biogeochemistry activity and nutrients transportation in soils, but studies regarding the long-term effects of green manures on the content and structure of DOM in red paddy soil have not been reported yet. A long-term green manure experiment established in 1982 was utilized to test the DOM contents in different treatments, and the spectral characteristics of DOM were investigated by using ultraviolet-visible(UV-Vis) spectrometry and Fourier transform infrared(FTIR) spectrometry. The experiment included four cropping systems: ricerice-milk vetch(RRV), rice-rice-rape(RRP), rice-rice-ryegrass(RRG) and rice-rice-winter fallow(RRF), among them, milk vetch, rape, and ryegrass are popular winter green manure species in southern China. The results showed that the content of dissolved organic carbon(DOC), which is widely used to estimate the concentration of DOM, was significantly promoted after the incorporation of green manures compared with the other sampling stages. The contents of aromatic groups and the degree of humification of DOM increased in RRV and RRP, suggesting more complex compositions of the soil DOM after long-term application of milk vetch and rape. The contents of phenol, alcohol and carboxylic acid group at the mature stage of early rice were significantly higher than those at the stage of after green manures turned over, especially for the RRV treatment. The absorption ratio of FTIR indicated that winter plantation of rape increased the aromatic-C/aliphatic-C ratio, and ryegrass increased the aromatic-C/carboxyl-C ratio. In conclusion, long-term planting of milk vetch and rape as green manures increased the degree of aromaticity, humification and average molecular weight of DOM, and made the DOM more stable in red paddy soil.GAO Song-juan GAO Ju-sheng CAO Wei-dong ZOU Chun-qin HUANG Jing BAI Jinshun DOU Fu-gen 2018Journal of Integrative Agriculture2018,17,8:21
17Identification of coastal wetlands of international importance for waterbirds:a review of China Coastal Waterbird Surveys 2005–2013显示文摘Background:China's coastal wetlands belong to some of the most threatened ecosystems worldwide.The loss and degradation of these wetlands seriously threaten waterbirds that depend on wetlands.Methods:The China Coastal Waterbird Census was organized by volunteer birdwatchers in China's coastal region.Waterbirds were surveyed synchronously once every month at 14 sites,as well as irregularly at a further 18 sites,between September 2005 and December 2013.Results:A total of 75 species of waterbirds met the 1 % population level Ramsar listing criterion at least once at one site.The number of birds of the following species accounted for over 20 % of the total flyway populations at a single site:Mute Swan(Cygnus olor),Siberia Crane(Grus leucogeranus),Far Eastern Oystercatcher(Haematopus osculans),Bar-tailed Godwit(Limosa lapponica),Spotted Greenshank(Tringa guttifer),Great Knot(Calidris tenuirostris),Spoon-billed Sandpiper(Calidris pygmeus),Saunders' s Gull(Larus saundersi),Relict Gull(Larus relictus),Great Cormorant(Phalacrocorax carbo),Eurasian Spoonbill(Platalea leucorodia),Black-faced Spoonbill(Platalea minor) and Dalmatian Pelican(Pelecanus crispus).A total of 26 sites supported at least one species of which their number met the1 % criterion.Forty-two species met the 1 % criterion in the Yellow River Delta,Shandong;29 at the Cangzhou coast,Hebei and 26 species at the Lianyungang coast,Jiangsu.Conclusions:The results highlight the international importance of China's coastal wetlands for waterbirds.This study also demonstrates that participation of local birdwatchers in waterbird surveys results in data that are invaluable not only for understanding the current status of waterbirds in China's coastal regions but also for waterbird conservation and management.Qingquan Bai Jianzhong Chen Zhihong Chen Guotai Dong Jiangtian Dong Wenxiao Dong Vivian Wing Kan Fu Yongxiang Han Gang Lu Jing Li Yang Liu Zhi Lin Derong Meng Jonathan Martinez Guanghui Ni Kai Shan Renjie Sun Suixing Tian Fengqin Wang Zhiwei Xu Yat-tung Yu Jin Yang Zhidong Yang Lin Zhang Ming Zhang Xiangwu Zeng 2015Chinese Birds2015,,3:20
18Exploring an Integrative Therapy for Treating COVID-19:A Randomized Controlled Trial显示文摘Objectives:To develop a new Chinese medicine(CM)-based drug and to evaluate its safety and effect for suppressing acute respiratory distress syndrome(ARDS)in COVID-19 patients.Methods:A putative ARDS-suppressing drug Keguan-1 was first developed and then evaluated by a randomized,controlled two-arm trial.The two arms of the trial consist of a control therapy(alpha interferon inhalation,50(x g twice daily;and lopinavir/ritonavir,400 and 100 mg twice daily,respectively)and a testing therapy(control therapy plus Keguan-119.4 g twice daily)by random number table at 1:1 ratio with 24 cases each group.After 2-week treatment,adverse events,time to fever resolution,ARDS development,and lung injury on newly diagnosed COVID-19 patients were assessed.Results:An analysis of the data from the first 30 participants showed that the control arm and the testing arm did not exhibit any significant differences in terms of adverse events.Based on this result,the study was expanded to include a total of 48 participants(24 cases each arm).The results show that compared with the control arm,the testing arm exhibited a significant improvement in time to fever resolution(P=0.035),and a significant reduction in the development of ARDS(P=0.048).Conclusions:Keguan-1-based integrative therapy was safe and superior to the standard therapy in suppressing the development of ARDS in COVID-19 patients.(Trial registration No.NCT 04251871 at www.clinicaltrials.gov).WANG Jia-bo WANG Zhong-xia JING Jing ZHAO Peng DONG Jing-hui ZHOU Yong-feng YANG Guang NIU Ming ZHAO Xu JIANG Tian-jun Bl Jing-feng XU Zhe ZHANG Ping WU Dan BAI Zhao-fang GUO Yu-ming YU Si-miao SUN Yong-qiang ZHANG Zi-teng ZHAN Xiao-yan LI Peng-yan DING Jin-biao ZHAO Peng-fei SONG Xue-ai TANG Jian-yuan HE Dong-chu CHEN Zhu QIN En-qiang WANG Rui-lin XIAO Xiao-he 2020Chinese Journal of Integrative Medicine2020,26,9:18
19GYY4137 protects against myocardial ischemia and reperfusion injury by attenuating oxidative stress and apoptosis in rats显示文摘Hydrogen sulfide(H_2S) is a gasotransmitter that regulates cardiovascular functions.The present study aimed to determine the protective effect of slow-releasing H_2S donor GYY4137 on myocardial ischemia and reperfusion(I/R) injury and to investigate the possible signaling mechanisms involved.Male Sprague-Dawley rats were treated with GYY4137 at 12.5 mg/(kg·day),25 mg/(kg·day) or 50 mg/(kg·day) intraperitoneally for7 days.Then,rats were subjected to 30 minutes of left anterior descending coronary artery occlusion followed by reperfusion for 24 hours.We found that GYY4137 increased the cardiac ejection fraction and fractional shortening,reduced the ischemia area,alleviated histological injury and decreased plasma creatine kinase after myocardial I/R.Both H_2S concentration in plasma and cystathionine-γ-lyase(CSE) activity in the myocardium were enhanced in the GYY4137 treated groups.GYY4137 also decreased malondialdehyde and myeloperoxidase levels in serum,attenuated superoxide anion level and suppressed phosphorylation of mitogen activated protein kinases in the myocardium after I/R.Meanwhile,GYY4137 increased the expression of Bcl-2 but decreased the expression of Bax,caspase-3 activity and apoptosis in the myocardium.The data suggest that GYY4137 protects against myocardial ischemia and reperfusion injury by attenuating oxidative stress and apoptosis.Guoliang Meng Jing Wang Yujiao Xiao Wenli Bai Liping Xie Liyang Shan Philip K Moore Yong Ji 2015The Journal of Biomedical Research2015,29,3:18
20Effect of electroacupuncture on expression of Ang/Tie-2 mRNA and protein in rats with acute cerebral infarction显示文摘OBJECTIVE: To identify the intervention mechanism of the effect of electroacupuncture on the expression of Ang/Tie-2 m RNA and protein in rats with acute cerebral infarction induced by middle cerebral artery occlusion(MCAO).METHODS: Altogether 120 Wistar rats were subjected to MCAO by inserting a nylon filament, andthen divided into 3 groups: control group, injured group and electroacupuncture group. The injured and electroacupuncture groups were further divided into the following 7 subgroups according to the time after MCAO: 3, 6, 12, 24 h, 3, 7 and 12 d, with 8 rats in each subgroup. The electroacupuncture group was given electroacupuncture treatment at Shuigou(GV 26) instantly after operation. The rats were killed at different time points according to their groups, and then the expression levels of Ang/Tie-2 m RNA and protein were detected using Real-Time polymerase chain reaction and immunohistochemical staining.RESULTS: The m RNA and protein expression levels of Ang/Tie-2 in the electroacupuncture group were significant higher than that in the injured group.CONCLUSION: The results suggested that electroacupuncture could significantly regulate the expression of Ang/Tie-2 m RNA and protein in the rats with acute cerebral infarction induced by MCAO, and enhance angiogenesis after ischemic penumbra.Li Jing Bai Zonglu Du Yuanhao Li Yongfeng Zhang Xuezhu Pang Bo Zhang Jingjing 2017Journal of Traditional Chinese Medicine2017,37,5:17
