1A single center investigation of bare-metal or drug-eluting stent restenosis from 1633 consecutive Chinese Han ethnic patients显示文摘Background Stents are widely used in China but the clinical impression is somehow that restenosis is less common because of the lower prevalence of coronary artery disease (CAD) and associated risk factors in Chinese populations. However, no large-sample published studies are available on angiographic stent restenosis including those of bare-metal stent (BMS) or drug-eluting stent (DES) in Chinese Han ethnic population. Mothods A total of 1633 consecutive patients with CAD who had undergone coronary stenting, quantitative coronary angiography (QCA) were retrospectively studied. At the time of stent implantation and at 7 months post-stenting 675 patients had a follow-up angiography. Statistical analysis was made with the chi-square test for categorical variables, unpaired t test for continuous variables, univariate or multivariate regression for baseline and angiographic characteristics and the Kaplan-Meier method for rate of target lesion revascularization (TLR). Results Stent restenosis was defined as ≥50% diameter stenosis in the dilated segment. A total of 675 patients with 1074 lesions were subjected to angiographic follow-up for 7 months on average. Of these lesions, 448 were implanted with BMS whereas 626 lesions with DES. At 7 months, bare-metal in-stent restenosis occured in 148 lesions (33.0%), and bare metal in-segment restenosis in 155 lesions (34.6%) in contrast to drug-eluting in-stent restenosis in 48 lesions (7.7%) and drug-eluting in-segment restenosis in 73 lesions (11.7%) (P<0.001 compared with BMS respectively). Late loss in both in-stent and in segment was higher in BMS than in DES groups [(1.00±0.69) vs (0.28±0.52); (0.78±0.71) vs (0.21±0.52), P<0.001 respectively]. Angulated lesion, lesion length, pre-procedural minimal luminal diameter (MLD), and BMS were independent predictors for TLR, (P<0.01 respectively), whereas current smoker, ostial lesion, and stent overlapping, post-procedure in-stent MLD, lesion length, and stent types were independent predictors for in-segment restenosis (P<0.01 respectively). Standard coronary risk factors such as hypertension, hyperlipidemia, diabetes, and history of CAD were not associated with a higher rate of restenosis caused by BMS or DES implantation in our Chinese Han ethnic population. Conclusions Coronary stenting including BMS or DES implantation in Chinese Han ethnic patients is associated with a restenosis rate comparable to that demonstrated in previous studies from the western countries, and predictors of stent restenosis are somehow different from those in the western population.XU Bo LI Jian-jun YANG Yue-jin MA Wei-hua CHEN Ji-lin QIAO Shu-bin QIN Xue-wen YAO Min LIU Hai-bo WU Yong-jian YUAN Jin-qing CHEN Jue YOU Shi-jie DAI Jun XIA Ran GAO Run-lin 2006Chinese Medical Journal2006,,7:23

6Fatal complications in a patient with severe multi-space infections in the oral and maxillofacial head and neck regions: A case report显示文摘BACKGROUND Odontogenic infection is one of the common infectious diseases in oral and maxillofacial head and neck regions.Clinically,if early odontogenic infections such as acute periapical periodontitis,alveolar abscess,and pericoronitis of wisdom teeth are not treated timely,effectively and correctly,the infected tissue may spread up to the skull and brain,down to the thoracic cavity,abdominal cavity and other areas through the natural potential fascial space in the oral and maxillofacial head and neck.Severe multi-space infections are formed and can eventually lead to life-threatening complications(LTCs),such as intracranial infection,pleural effusion,empyema,sepsis and even death.CASE SUMMARY We report a rare case of death in a 41-year-old man with severe odontogenic multi-space infections in the oral and maxillofacial head and neck regions.One week before admission,due to pain in the right lower posterior teeth,the patient placed a cigarette butt dipped in the pesticide'Miehailin'into the'dental cavity'to relieve the pain.Within a week,the infection gradually spread bilaterally to the floor of the mouth,submandibular space,neck,chest,waist,back,temporal and other areas.The patient had difficulty breathing,swallowing and eating,and was transferred to our hospital as an emergency admission.Following admission,oral and maxillofacial surgeons immediately organized consultations with doctors in otolaryngology,thoracic surgery,general surgery,hematology,anesthesia and the intensive care unit to assist with treatment.The patient was treated with the highest level of antibiotics(vancomycin)and extensive abscess incision and drainage in the oral,maxillofacial,head and neck,chest and back regions.Unfortunately,the patient died of septic shock and multiple organ failure on the third day after admission.CONCLUSION Odontogenic infection can cause serious multi-space infections in the oral and maxillofacial head and neck regions,which can result in multiple LTCs.The management and treatment of LTCs such as multi-space infections should be multidisciplinary led by oral and maxillofacial surgeons.Tian-Guo Dai Hong-Bing Ran Yin-Xiu Qiu Bo Xu Jin-Qiang Cheng Ying-Kai Liu 2019World Journal of Clinical Cases2019,7,23:14
7Preparation of activated carbon from cattail and its application for dyes removal显示文摘Activated carbon was prepared from cattail by H3PO4 activation. The effects influencing the surface area of the resulting activated carbon followed the sequence of activated temperature > activated time > impregnation ratio > impregnation time. The optimum condition was found at an impregnation ratio of 2.5, an impregnation time of 9 hr, an activated temperature of 500°C, and an activated time of 80 min. The Brunauer-Emmett-Teller surface area and average pore size of the activated carbon were 1279 m2/g and 5.585 nm, respectively. A heterogeneous structure in terms of both size and shape was highly developed and widely distributed on the carbon surface. Some groups containing oxygen and phosphorus were formed, and the carboxyl group was the major oxygen-containing functional group. An isotherm equilibrium study was carried out to investigate the adsorption capacity of the activated carbon. The data fit the Langmuir isotherm equation, with maximum monolayer adsorption capacities of 192.30 mg/g for Neutral Red and 196.08 mg/g for Malachite Green. Dye-exhausted carbon could be regenerated effectively by thermal treatment. The results indicated that cattail-derived activated carbon was a promising adsorbent for the removal of cationic dyes from aqueous solutions.Qianqian Shi Jian Zhang Chenglu Zhang Cong Li Bo Zhang Weiwei Hu Jingtao Xu Ran Zhao 2010Journal of Environmental Sciences2010,22,1:13

9Risks faced by donors of right lobe for living donor liver transplantation显示文摘BACKGROUND:Because of the shortage of deceased donors with livers fit for transplantation,living donor liver transplantation(LDLT)is becoming an attractive alternative.Attention should be paid to the donors,especially to those of the right lobe.In this study,we evaluated the risks faced by donors of the right lobe for adult-to-adult LDLT.METHODS:The perioperative data from 105 consecutive living donors of the right lobe performed in West China Hospital from January 2002 to December 2007 were retrospectively studied.Preoperative evaluation included CT,MRCP,and intraoperative cholangiography,showing liver volume,hepatic vasculature and the biliary system.The standard liver volume(SLV)and the ratio of left lobe volume to SLV were calculated.The right lobe grafts were obtained by transecting the liver on the right side of the middle hepatic vein without inflow vascular occlusion,using an ultrasonic dissector.After operation the donors were monitored in the Intensive Care Unit for about three days.Each donor was followed up for at least 6 months.RESULTS:There was no donor mortality.Major complications occurred in 14 donors(13.3%),of whom 3 received conservative treatment,8 required invasive paracentesis,and 3 required further surgery.All donors were recovered well and resumed their previous occupations.CONCLUSIONS:Donors of the right lobe face low risks.The preoperative evaluation,especially evaluation of the volume of the remnant liver,should be exact.During the operation,the patency of the remnant hepatic vasculature and bile duct must be preserved,and the extent of injury to the remnant liver should be limited as much as possible.The detection and treatment of postoperative complications should be diligently performed.Ran, Shun Wen, Tian-Fu Yan, Lu-Nan Li, Bo Zeng, Yong Chen, Zhe-Yu Zhang, Yu Liao, Zhi-Xue Liang, Guan-Lin Li, Guo Zhang, Xian-Hua 2009Hepatobiliary & Pancreatic Diseases International2009,8,6:8

11Reservoir Characteristics and Preservation Conditions of Longmaxi Shale in the Upper Yangtze Block, South China显示文摘The Upper Ordovician-Lower Silurian Longmaxi Shale in the Upper Yangtze block represents one of the most important shale gas plays in China. The shale composition,porosity,organic thermal maturity,and methane sorption were investigated at the Qilongcun section in the Dingshan area,southeastern Sichuan Basin. The results show that the Upper Ordovician-Lower Silurian Longmaxi Shale contains:(1) sapropelic I organic matter;(2) a 40-m thick bedded sequence where total organic carbon(TOC) content is > 2%;(3) a 30-m thick layer at the base of the Longmaxi Shale with a brittle mineral content higher than 50%; and(4) a mean methane adsorption capacity of 1.80 cm^3/g(7 MPa pressure). A positive correlation between TOC and sorbed gas indicates that organic matter content exerts an important control on methane storage capacity. Based on the analysis of the shale reservoir characteristics,the lower member of the Longmaxi Shale can thus be considered a favorable stratum for shale gas exploration and exploitation. It has similar reservoir characteristics with the Longmaxi Shale in the Jiaoshiba area tested with a high-yield industrial gas flow. However,based on tectonic analysis,differences in the level of industrial gas flow between the low-yield study area and the high-yield Jiaoshiba area may result from different tectonic preservation conditions. Evidence from these studies indicates the shale gas potential of the Longmaxi Shale is constrained by the reservoir and preservation conditions.RAN Bo LIU Shugen Luba JANSA SUN Wei YANG Di WANG Shiyu YE Yuehao Christopher XIAO ZHANHG Jian ZHAI Cangbo LUO Chao ZHANG Changjun 2016Acta Geologica Sinica(English Edition)2016,90,6:6
12Advances in lung cancer screening and early detection显示文摘Lung cancer is associated with a heavy cancer-related burden in terms of patients’physical and mental health worldwide.Two randomized controlled trials,the US-National Lung Screening Trial(NLST)and Nederlands-Leuvens Longkanker Screenings Onderzoek(NELSON),indicated that low-dose CT(LDCT)screening results in a statistically significant decrease in mortality in patients with lung cancer,LDCT has become the standard approach for lung cancer screening.However,many issues in lung cancer screening remain unresolved,such as the screening criteria,high false-positive rate,and radiation exposure.This review first summarizes recent studies on lung cancer screening from the US,Europe,and Asia,and discusses risk-based selection for screening and the related issues.Second,an overview of novel techniques for the differential diagnosis of pulmonary nodules,including artificial intelligence and molecular biomarker-based screening,is presented.Third,current explorations of strategies for suspected malignancy are summarized.Overall,this review aims to help clinicians understand recent progress in lung cancer screening and alleviate the burden of lung cancer.Caichen Li Huiting Wang Yu Jiang Wenhai Fu Xiwen Liu Ran Zhong Bo Cheng Feng Zhu Yang Xiang Jianxing He Wenhua Liang 2022Cancer Biology & Medicine2022,19,5:6
13USP29 maintains the stability of cGAS and promotes cellular antiviral responses and autoimmunity显示文摘Cyclic GMP-AMP synthase(cGAS)is an essential sensor of cytosolic DNA and critically mediates innate immune responses and autoimmunity.Modulating the activity and stability of cGAS provides potential strategies for treating viral or autoimmune diseases.Here,we report that ubiquitin-specific protease 29(USP29)deubiquitinates and stabilizes cGAS and promotes cellular antiviral responses and autoimmunity.Knockdown or knockout of USP29 severely impairs Herpes simplex virus 1(HSV-1)-or cytosolic DNA-induced expression of type I interferons(IFNs)and proinflammatory cytokines.Consistently,Usp29m/m mice produce decreased type I IFNs and proinflammatory cytokines after HSV-1 infection and are hypersensitive to HSV-1 infection compared to the wild-type littermates.In addition,genetic ablation of USP29 in Trex1−/−mice eliminated the detectable pathological and molecular autoimmune phenotypes.Mechanistically,USP29 constitutively interacts with cGAS,deconjugates K48-linked polyubiquitin chains from cGAS and stabilizes cGAS in uninfected cells or after HSV-1 infection.Reconstitution of cGAS into Usp29−/−cells fully rescues type I IFN induction and cellular antiviral responses after HSV-1 infection.Our findings thus reveal a critical role of USP29 in the innate antiviral responses against DNA viruses and autoimmune diseases and provide insight into the regulation of cGAS.Qiang Zhang Zhen Tang Ran An Liya Ye Bo Zhong 2020Cell Research2020,30,10:5

16The histone methyltransferase EZH2 primes the early differentiation of follicular helper T cells during acute viral infection显示文摘Epigenetic modifications to histones dictate the differentiation of naïve CD4^(+) T cells into different subsets of effector T helper(TH)cells.The histone methyltransferase enhancer of zeste homolog 2(EZH2)has been implicated in the mechanism regulating the differentiation of TH1,TH2 and regulatory T(Treg)cells.However,whether and how EZH2 regulates follicular helper T(TFH)cell differentiation remain unknown.Using a mouse model of acute lymphocytic choriomeningitis virus(LCMV)infection,we observed abundant EZH2 expression and associated H3K27me3 modifications preferentially in the early committed virus-specific TFH cells compared to those in TH1 cells.Ablation of EZH2 in LCMV-specific CD4^(+) T cells leads to a selective impairment of early TFH cell fate commitment,but not late TFH differentiation or memory TFH maintenance.Mechanistically,EZH2 specifically stabilizes the chromatin accessibility of a cluster of genes that are important for TFH fate commitment,particularly B cell lymphoma 6(Bcl6),and thus directs TFH cell commitment.Therefore,we identified the chromatin-modifying enzyme EZH2 as a novel regulator of early TFH differentiation during acute viral infection.Xiangyu Chen Guoshuai Cao Jialin Wu Xinxin Wang Zhiwei Pan Jianbao Gao Qin Tian Lifan Xu Zhirong Li Yaxing Hao Qizhao Huang Pengcheng Wang Minglu Xiao Luoyingzi Xie Shupei Tang Zhenyu Liu Li Hu Jianfang Tang Ran He Li Wang Xinyuan Zhou Yuzhang Wu Mengjie Chen Beicheng Sun Bo Zhu Jun Huang Lilin Ye 2020Cellular & Molecular Immunology2020,17,3:4
17Factors influencing the natural regeneration of arrow bamboo in giant panda habitat of the north Minshan Mountains,southwestern China显示文摘To determine the effects of eco-factors on the regeneration of arrow bamboo in giant panda habitat,a field study was conducted in the Baozuo and Gonggangling Nature Reserves,Sichuan Province,China.A total of 183 quadrats(10 m×10 m) and 717 small quadrats(1 m×1 m) were investigated within the study site.Bamboo seedling density was used as an indicator of natural regeneration.Twelve factors were measured,which included topography and forest factors(elevation,slope aspect,slope degree,slope position,canopy cover,and shrub cover) and microhabitat factors(upper vegetation cover,herb cover,litter layer cover,moss cover,moss thickness,and dead bamboo density).A One-Way ANOVA was used to analyze the effects of topography and forest factors on seedling density,and a GLM(Generalized Linear Model) procedure was performed to examine the relationship between seedling density and microhabitat factors.The results indicated that elevation and canopy cover had highly significant effects on seedling density:bamboo seedling density was highest and showed the best regeneration at middle elevations(2800-3000 m) and under medium to medium-high canopy cover.Moss thickness,moss cover,and dead bamboo density were the most important microhabitat factors influencing the natural regeneration of bamboo:seedling density increased with increasing moss cover and moss thickness and decreased with increasing dead bamboo density.We propose that removal of dead bamboo and controlling grazing activities may accelerate the process of bamboo regeneration.LI Bo ZHANG Man ZHONG Xue MOERMOND Timothy RAN JiangHong YANG XuYu 2013Chinese Science Bulletin2013,58,17:4
18Application of imidacloprid controlled-release granules to enhance the utilization rate and control wheat aphid on winter wheat显示文摘During winter wheat production, aphids need to be controlled with pesticides for the entire growth period. Controlled-release technology has been regarded as an alternative method for the improvement of pesticide efficiency. This study investigated two types of imidacloprid controlled-release granule (CR-GR): 2% imidacloprid CR-GR and 0.2% imidacloprid pesticide-fertilizer controlled-release granule (PF-CR-GR) when wheat was sown in winter. The release performance, utilization rate, terminal residues in edible parts, control effect on aphids, and achieved winter wheat yield were evaluated for both laboratory experiments and field application. Imidacloprid PF-CR-GR released more quickly in aqueous medium than CR-GR because of its good water solubility. After CR-GR treatments, the concentrations in wheat roots and soil were similar throughout the entire sampling period, and the concentrations in shoots were about 10–20% of those in roots. Imidacloprid was better absorbed when CR-GR was used as root treatment, compared with foliar treatment. Field application showed that imidacloprid CR-GR and PF-CR-GR controlled aphids throughout the entire growth period of winter wheat and improved the wheat yield. These findings identified application of imidacloprid CR-GR and PF-CR-GR on winter wheat as an effective way to enhance the pesticide utilization rate and ensure adequate yield.

20Effect of integrated Traditional Chinese and Western Medicine on Gout显示文摘OBJECTIVE:To evaluate the curative effect of integrated Traditional Chinese and Western Medicine on gout,and to investigate the therapy timing and exact treatment options of integrated medicine.METHODS:Totally 860 patients were enrolled,including 460 patients with intermittent gout,200 patients with active Traditional Chinese Medicine(TCM)syndrome(TCM syndrome score≥6)and200 patients with stable TCM syndrome(score<6).They were randomly divided into intervention and control groups.The control group was treated according to Western Medicine guidelines.The intervention group was treated with integrated Traditional Chinese and Western Medicine.The efficacy of TCM syndrome,joint pain score,joint swelling score,ESR,C-reactive protein,serum uric acid,liver and kidney function,and the duration of remission of TCM syndrome were compared between the two groups before and after treatments.RESULTS:For the patients with stable TCM syndrome,there was no significant difference in the effective rate and inefficiency between the intervention group and the control group.For the active type,the effective rate of the intervention group is better than the control group significantly.For the stable type,there was no significant difference between the intervention group and the control group in improving the scores of joint pain and swelling,reducing the level of ESR,C-reactive protein,serum uric acid and improving liver and kidney function.For the active type,the differences between the two groups were significant.The stable stage of gout in the intervention group was longer than the control group.CONCLUSION:For the gout patients with stable TCM syndrome in the acute stage of gout,we can use TCM treatment or Western Medicine alternatively;for the patients with active TCM syndrome,the scheme of combination of Traditional Chinese and Western Medicine can be applied,with the better curative effect than any medicine alone.LIU Wei WU Yuanhao XUE Bin JIN Yue ZHANG Shumin LI Peihao XIE Qing WANG Aihua GAO Jingyue CAI Yue ZHANG Bo LIU Xiaoya WANG Yi DUAN Ran 2021Journal of Traditional Chinese Medicine2021,41,5:3
