1Osteoarthritis:toward a comprehensive understanding of pathological mechanism显示文摘Osteoarthritis(OA) is the most common degenerative joint disease and a major cause of pain and disability in adult individuals. The etiology of OA includes joint injury, obesity, aging, and heredity. However, the detailed molecular mechanisms of OA initiation and progression remain poorly understood and, currently,there are no interventions available to restore degraded cartilage or decelerate disease progression. The diathrodial joint is a complicated organ and its function is to bear weight, perform physical activity and exhibit a joint-specific range of motion during movement. During OA development, the entire joint organ is affected, including articular cartilage, subchondral bone, synovial tissue and meniscus. A full understanding of the pathological mechanism of OA development relies on the discovery of the interplaying mechanisms among different OA symptoms, including articular cartilage degradation, osteophyte formation, subchondral sclerosis and synovial hyperplasia, and the signaling pathway(s) controlling these pathological processes.Di Chen Jie Shen Weiwei Zhao Tingyu Wang Lin Han John L Hamilton Hee-Jeong Im 2017Bone Research2017,5,1:121
2A rapid advice guideline for the diagnosis and treatment of 2019 novel coronavirus(2019-nCoV) infected pneumonia(standard version)显示文摘In December 2019, a new type viral pneumonia cases occurred in Wuhan, Hubei Province;and then named '2019 novel coronavirus(2019-nCoV)' by the World Health Organization(WHO) on 12 January 2020. For it is a never been experienced respiratory disease before and with infection ability widely and quickly, it attracted the world’s attention but without treatment and control manual. For the request from frontline clinicians and public health professionals of 2019-nCoV infected pneumonia management, an evidence-based guideline urgently needs to be developed. Therefore, we drafted this guideline according to the rapid advice guidelines methodology and general rules of WHO guideline development;we also added the first-hand management data of Zhongnan Hospital of Wuhan University. This guideline includes the guideline methodology, epidemiological characteristics, disease screening and population prevention, diagnosis, treatment and control(including traditional Chinese Medicine), nosocomial infection prevention and control, and disease nursing of the 2019-nCoV. Moreover, we also provide a whole process of a successful treatment case of the severe 2019-nCoV infected pneumonia and experience and lessons of hospital rescue for 2019-nCoV infections. This rapid advice guideline is suitable for the first frontline doctors and nurses, managers of hospitals and healthcare sections, community residents, public health persons, relevant researchers, and all person who are interested in the 2019-nCoV.Ying-Hui Jin Lin Cai Zhen-Shun Cheng Hong Cheng Tong Deng Yi-Pin Fan Cheng Fang Di Huang Lu-Qi Huang Qiao Huang Yong Han Bo Hu Fen Hu Bing-Hui Li Yi-Rong Li Ke Liang Li-Kai Lin Li-Sha Luo Jing Ma Lin-Lu Ma Zhi-Yong Peng Yun-Bao Pan Zhen-Yu Pan Xue-Qun Ren Hui-Min Sun Ying Wang Yun-Yun Wang Hong Weng Chao-Jie Wei Dong-Fang Wu Jian Xia Yong Xiong Hai-Bo Xu Xiao-Mei Yao Yu-Feng Yuan Tai-Sheng Ye Xiao-Chun Zhang Ying-Wen Zhang Yin-Gao Zhang Hua-Min Zhang Yan Zhao Ming-Juan Zhao Hao Zi Xian-Tao Zeng Yong-Yan Wang Xing-Huan Wang 2020Military Medical Research2020,7,1:161

4Multiple genetic alterations and behavior of cellular biology in gastric cancer and other gastric mucosal lesions:H.pylori infection,histological types and staging显示文摘AIM To investigate the expression of multiplegenes and the behavior of cellular biology ingastric cancer(GC)and other gastric mucosallesions and their relations to Helicobacter pylori(H.pylori)infection,tumor staging andhistological subtypes.METHODS Three hundred and twenty-sevenspecimens of gastric mucosa obtained viaendoscopy or surgical resection,and ABCimmunohistochemical staining were used todetect the expression of p53,p16,Bcl-2 andCOX-2 proteins.H.pylori was determined byrapid urea test combined with pathologicalstaining or14C urea breath test.Cellular image analysis was performed in 66 patients withintestinal metaplasia(IM)and/or dysplasia(Dys).In 30 of them,both cancer and theparacancerous tissues were obtained at the timeof surgery.Histological pattern,tumor staging,lymph node metastasis,grading ofdifferentiation and other clinical data werestudied in the medical records.RESULTS p16 expression of IM or Dys wassignificantly lower in positive H.pylori chronicatrophic gastritis(CAG)than those withnegative H.pylori(CAG:54.8% vs 88.0%,IM:34.4% vs 69.6%,Dys:23.8% vs 53.6%,allP<0.05),Bcl-2 or COX-2 expression of IM orDys in positive H.pylori cases was significantlyhigher than that without H.pylori(Bcl-2:68.8%vs23.9%,90.5% vs 60.7%;COX-2:50.0% vs10.8%,61.8% vs 17.8%;all P<0.05).Themean number of most parameters of cellularimage analysis in positive H.pylori group wassignificantly higher than that in negative H.pylori group(Ellipser:53±14,40±12μm,Area1:748±572,302±202 μm2,Area2:3050±1661,1681±1990 μm2,all P<0.05;Ellipseb:79±23,58±15 μm,Ratio1:22%±5%,13%±4%,Ratio2:79%±17%,53%±20%,all P<0.01).There was significant correlation between Bcl-2and histologic pattern of gastric carcinoma,andbetween COX-2 and tumor staging or lymph nodemetastasis(Bcl-2:75.0% vs 16.7%;COX-2:76.0% vs 20.0%,79.2% vs 16.7%;allP<0.05).CONCLUSION p1l6, Bcl-2, and COX-2 but not p53 gene may play a role in the early genesis/ progression of gastric carcinoma and are associated with H. pylori infection. p53 gene is relatively late event in gastric tumorigenesis and mainly relates to its progression. There is more cellular-biological behavior of malignant tumor in gastric mucosal lesions with H. pylori infection. Aberrant Bcl-2 protein expression appears to be preferentially associated with the intestinal type cancer. COX-2 seems to be related to tumor staging and lymph node metastasis.Heng Jun Gao Lian Zhen Yu Jian Feng Bai Yan Shen Peng Gu Sun Han Lin Zhao Kun Miu Xiu Zhen Lü Xiao Yong Zhang Zhi Quan Zhao 2000World Journal of Gastroenterology2000,6,6:52
52018 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 2018Science Bulletin2018,63,23:54

8Relationship of hepatitis B virus infection of placental barrier and hepatitis B virus intra-uterine transmission mechanism显示文摘AIM: To explore the mechanism of intra-uterine transmission,the HBV infection status of placental tissue and in vitro cultured placental trophoblastic cells was tested through in vivo and in vitro experiments. METHODS: A variety of methods,such as ELISA,RT- PCR,IHC staining and immunofluorescent staining were employed to test the HBV marker positive pregnant women's placenta and in vitro cultured placental trophoblastic cells. RESULTS: The HBV DNA levels in pregnant women's serum and fetal cord blood were correlated. For those cord blood samples positive for HBV DNA,their maternal blood levels of HBV DNA were at a high level. The HBsAg IHC staining positive cells could be seen in the placental tissues and the presence of HBV DNA detected. After co-incubating the trophoblastic cells and HBV DNA positive serum in vitro,the expressions of both HBsAg and HBV DNA could be detected. CONCLUSION: The mechanism of HBV intra-uterine infection may be due to that HBV breaches the placental barrier and infects the fetus.Han Bai Lin Zhang Li Ma Xiao-Guang Dou Guo-He Feng Gui-Zhen Zhao 2007World Journal of Gastroenterology2007,13,26:30
9Antidiabetic Effects of Gegen Qinlian Decoction via the Gut Microbiota Are Attributable to Its Key Ingredient Berberine显示文摘Gegen Qinlian Decoction(GQD),a traditional Chinese medicine(TCM)formula,has long been used for the treatment of common metabolic diseases,including type 2 diabetes mellitus.However,the main limitation of its wider application is ingredient complexity of this formula.Thus,it is critically important to identify the major active ingredients of GQD and to illustrate mechanisms underlying its action.Here,we compared the effects of GQD and berberine,a hypothetical key active pharmaceutical ingredient of GQD,on a diabetic rat model by comprehensive analyses of gut microbiota,short-chain fatty acids,proinflammatory cytokines,and ileum transcriptomics.Our results show that berberine and GQD had similar effects on lowering blood glucose levels,modulating gut microbiota,inducing ileal gene expression,as well as relieving systemic and local inflammation.As expected,both berberine and GQD treatment significantly altered the overall gut microbiota structure and enriched many butyrate-producing bacteria,including Faecalibacterium and Roseburia,thereby attenuating intestinal inflammation and lowering glucose.Levels of short-chain fatty acids in rat feces were also significantly elevated after treatment with berberine or GQD.Moreover,concentration of serum proinflammatory cytokines and expression of immune-related genes,including Nfkb1,Stat1,and Ifnrg1,in pancreatic islets were significantly reduced after treatment.Our study demonstrates that the main effects of GQD can be attributed to berberine via modulating gut microbiota.The strategy employed would facilitate further standardization and widespread application of TCM in many diseases.Xizhan Xu Zezheng Gao Fuquan Yang Yingying Yang Liang Chen Lin Han Na Zhao Jiayue Xu Xinmiao Wang Yue Ma Lian Shu Xiaoxi Hu Na Lyu Yuanlong Pan Baoli Zhu Linhua Zhao Xiaolin Tong Jun Wang 2020Genomics, Proteomics & Bioinformatics2020,18,6:29
10Oral berberine improves brain dopa/dopamine levels to ameliorate Parkinson’s disease by regulating gut microbiota显示文摘The phenylalanine-tyrosine-dopa-dopamine pathway provides dopamine to the brain.Iin this process,tyrosine hydroxylase(TH)isthe rate-limiting enzyme that hydroxylates tyrosine and generates levodopa(L-dopa)with tetranydrobiopterin(BH_(4))as a coenzyme.Here,we show that oral berberine(BBR)might supply H^(·) through dihydroberberine(reduced BBR produced by bacterial nitroreductase)and promote the production of BHl from dihydrobiopterin;the increased BH,enhances TH activity,which accelerates the production of L-dopa by the gut bacteria.Oral BBR acts in a way similar to vitamins.The L-dopa produced by theintestinal bacteria enters the brain through the circulation and is transformed to dopamine.To verify the gut-brain dialog activatedby BBR's effect,Enterococcus foecalis or Enterococcus faecium was transplanted into Parkinson's disease(PD)mice.The bacteriasignificantly increased brain dopamine and ameliorated PD manifestation in mice;additionally,combination of BBR with bacteriashowed better therapeutic effect than that with bacteria alone.Moreover,2,4,6-trimethy-pyranylium tetrafluoroborate(TMP-TFB)-derivatized matrix-assisted laser desorption mass spectrometry(MALDI-MS)imaging of dopamine identihed elevated striataldopamine levels in mouse brains with oral Enterococcus,and BBR strengthened the imaging intensity of brain dopamine.Theseresults demonstrated that BBR was an agonist of TH in Enterococcus and could lead to the production of L-dopa in the gut.Furthermore,a study of 28 patients with hyperlipidemia conhrmed that oral BBR increased bloodfecal L-dopa by the intestinalbacteria.Hence,BBR might improve the brain function by upregulating the biosynthesis of-dopa in the gut microbiota through avitamin-like effect.Yan Wang Qian Tong Shu-Rong Ma Zhen-Xiong Zhao Li-Bin Pan Lin Cong Pei Han Ran Peng Hang Yu Yuan Lin Tian-Le Gao Jia-Wen Shou Xiao-Yang Li Xian-Feng Zhang Zheng-Wei Zhang Jie Fu Bao-Ying Wen Jin-Bo Yu Xuetao Cao Jian-Dong Jiang 2021Signal Transduction and Targeted Therapy2021,6,3:16

12Genome Sequences Provide Insights into the Reticulate Origin and Unique Traits of Woody Bamboos显示文摘Polyploidization is a major driver of speciation and its importance to plant evolution has been well recognized.Bamboos comprise one diploid herbaceous and three polyploid woody lineages,and are members of the only major subfamily in grasses that diversified in forests,with the woody members having a tree-like lignified culm.In this study,we generated four draft genome assemblies of major bamboo lineages with three different ploidy levels(diploid,tetraploid,and hexaploid).We also constructed a high-density genetic linkage map for a hexaploid species of bamboo,and used a linkage-map-based strategy for genome assembly and identification of subgenomes in polyploids.Further phylogenomic analyses using a large dataset of syntenic genes with expected copies based on ploidy levels revealed that woody bamboos originated subsequent to the divergence of the herbaceous bamboo lineage,and experienced complex reticulate evolution through three independent allopolyploid events involving four extinct diploid ancestors.A shared but distinct subgenome was identified in all polyploid forms,and the progenitor of this subgenome could have been critical in ancient polyploidizations and the origin of woody bamboos.Important genetic clues to the unique flowering behavior and woody trait in bamboos were also found.Taken together,our study provides significant insights into ancient reticulate evolution at the subgenome level in the absence of extant donor species,and offers a potential model scenario for broad-scale study of angiosperm origination by allopolyploidization.Zhen-Hua Guo Peng-Fei Ma Guo-Qian Yang Jin-Yong Hu Yun-Long Liu En-Hua Xia Mi-Cai Zhong Lei Zhao Gui-Ling Sun Yu-Xing Xu You-Jie Zhao Yi-Chi Zhang Yu-Xiao Zhang Xue-Mei Zhang Meng-Yuan Zhou Ying Guo Cen Guo Jing-Xia Liu Xia-Ying Ye Yun-Mei Chen Yang Yang Bin Han Choun-Sea Lin Ying Lu De-Zhu Li 2019Molecular Plant2019,12,10:13
13HBV genotype C is independently associated with cirrhosis in community-based population显示文摘AIM:To determine the association of hepatitis B virus (HBV) genotypes with probable cirrhosis and fatty liver in community-based populations.METHODS: A multi-stage cluster probability sampling method was applied to recruit 10 167 subjects aged between 6 and 72 years from our epidemiological bases in Eastern China. After excluding the subjects co-infected with hepatitis C or hepatitis D viruses, the hepatitis B surface antigen (HBsAg)-positive subjects were examined for HBV genotype, serum viral load, alanine aminotransferase (ALT), hepatitis B e antigen (HBeAg) status, and ultrasonographic changes. Logistic regression models were used to determine the factors associated with probable cirrhosis and fatty liver.RESULTS: Of 634 HBsAg-positive subjects with HBV genotype determined, 82 had probable cirrhosis (ultrasonographic score ≥5), 42 had ultrasonographic fatty liver. Probable cirrhosis was only found in the HBeAg-negative subjects, and more frequently found in the subjects with genotype C than in those with genotype B (14.8% vs 8.0%, P=0.018). In HBeAg-negative subjects, high viral load was frequently asso-ciated with abnormal ALT level, while ALT abnormality was more frequent in those with probable cirrhosis than those without (19.5% vs 7.8%, P=0.001). Univariate analysis showed that age, sex, HBV genotypes, and viral load were not significantly associated with ultrasonographic fatty liver, whereas ALT abnormality was significantly related to ultrasonographic fatty liver (OR=4.54,95% CI:2.11-9.75, P<0.001). Multivariate analysis demonstrated that HBV genotype C, age (≥45 years), male sex, and ALT abnormality were independently associated with probable cirrhosis (AOR=2.30,95% CI:1.26-4.19; AOR =1.81,95% CI:1.10-2.99;AOR=1.74,95% CI:1.03-2.95; AOR=2.98,95% CI:1.48-5.99, respectively).CONCLUSION: A crude prevalence of probable cirrhosis is 12.9% in the community-based HBV-infected subjects. HBV genotype C is independently associated with probable cirrhosis in the HBeAg-negative subjects.Yin, Jian-Hua Zhao, Jun Zhang, Hong-Wei Xie, Jia-Xin Li, Wei-Ping Xu, Guo-Zhang Shen, Jie Dong, Hong-Jun Zhang, Jun Wang, Lin Han, Jian-Kang Wang, Hong-Yang Cao, Guang-Wen 2010World Journal of Gastroenterology2010,16,3:13

15A novel colloidal gold immunochromatography assay strip for the diagnosis of schistosomiasis japonica in domestic animals显示文摘Background:Schistosomiasis remains a major public health concern in China and an epidemiological survey has revealed that schistosome-infected bovines and goats are the main transmission sources for the disease.Therefore,development of a sensitive technique for the diagnosis of schistosomiasis in domestic animals is necessary.Method:A novel colloidal gold immunochromatography assay(GICA)strip was developed for detecting Schistosoma japonicum in domestic animals.The colloidal gold was conjugated with recombinant streptococcal protein G(rSPG).As the test and control lines,the schistosome soluble egg antigen and rSPG,respectively,were blotted on nitrocellulose membrane.Results:The lowest detectable serum dilution was 1∶640 for schistosome-infected buffaloes.The cross-reaction rate of GICA was 14.29%with Paramphistomum sp.in buffaloes,16.67%with Haemonchus sp.in goats,and 33.33%with Orientobilharzia sp.in goats.These results were slightly lower and similar to those obtained through ELISA.Moreover,the strips for detecting S.japonicum in mice,rabbits,buffaloes,and goats showed high sensitivity(100.00%,100.00%,100.00%,and 100.00%,respectively)and specificity(100.00%,100.00%,94.23%,and 88.64%,respectively).And the sensitivity or specificity of the GICA strips did not present any significant differences after storage for 12 months at room temperature.When compared with ELISA,the GICA strips exhibited similar sensitivity and specificity in the diagnosis of schistosomiasis in mice,rabbits,buffaloes,and goats.Besides,only 5μl of serum are required for the test and the detection can be completed within 5 min.Conclusion:This study is the first to develop a GICA strip using gold-rSPG conjugate for the diagnosing of schistosomiasis in domestic animals,and preliminary results showed that the developed strip may be suitable for large-scale screening of schistosomiasis in endemic areas.Rui Xu Jintao Feng Yang Hong Chao Lv Dengyun Zhao Jiaojiao Lin Ke Lu Hao Li Jinming Liu Xiaodan Cao Tao Wang Jinli Zai Zhaozhe Wang Bingguang Jia Qian Han Chuangang Zhu 2017Infectious Diseases of Poverty2017,6,1:12
16Autoantibodies in Chinese patients with chronic hepatitis B:Prevalence and clinical associations显示文摘AIM: To investigate the prevalence of autoantibodies and their associations with clinical features in Chinesepatients with chronic hepatitis B(CHB).METHODS: A total of 325 Chinese patients with CHB were enrolled in this retrospective,hospitalbased study.Patients with chronic hepatitis C(CHC),autoimmune hepatitis(AIH),or primary biliary cirrhosis(PBC) were included,with healthy donors acting as controls.A panel of autoantibodies that serologically define AIH and PBC was tested by indirect immunofluorescence assay and line immunoassay.The AIH-related autoantibody profile included homogeneous anti-nuclear antibodies(ANA-H),smooth-muscle antibodies,anti-liver kidney microsome type 1,antiliver cytosolic antigen type 1,and anti-soluble liver antigen/liver pancreas; the PBC-related antibodies were characterized by ANA-nuclear dots/membranous rimlike,anti-mitochondrial antibodies-M2(AMA-M2),antiBPO(recombinant antigen targeted by AMA-M2),antiSp100,anti-promyelocytic leukemia protein(anti-PML),and anti-gp210.The dichotomization of clustering was used to unequivocally designate the AIH or PBC profiles for each case.Anti-Ro52 antibodies were also tested.RESULTS: The prevalence of any autoantibody in CHB amounted to 58.2%,which was similar to the 66.2% prevalence in CHC,significantly higher than the 6.7% in the healthy controls(P < 0.001),and lower than the 100% found in AIH and PBC(P = 0.004 and P < 0.001,respectively).There were more anti-PML and anti-gp210 antibodies among the CHB patients than the CHC patients(11.1% vs 0%,P = 0.003; 12.6% vs 0%,P < 0.001,respectively).The prevalence and titer of AMA,anti-BPO,anti-PML,and anti-gp210 were higher in PBC than in those with CHB.Among the CHB patients,the prevalence of ANA,especially ANA-H,was significantly lower in patients with compensated and decompensated cirrhosis compared with patients without cirrhosis.Thirty-eight cases of hepatocellular carcinoma(HCC) in CHB showed a significant differencecompared with non-HCC patients in the prevalence of anti-PML(0% vs 12.5%,P = 0.013).Dichotomization of the autoantibodies revealed that the PBC profile was more prevalent in patients with CHB than in those with CHC,and that it was strongly correlated with both compensated and decompensated cirrhosis.In contrast,the prevalence of the AIH profile was significantly higher in non-cirrhosis patients with CHB than in those with compensated cirrhosis(18.5% vs 8.2%,P = 0.039).Moreover,the AIH profile was also closely associated with hepatitis B e-antigen positivity.CONCLUSION: ANA-H could be an indicator of earlystage CHB.Dichotomizing the autoantibody profiles revealed that the PBC profile is strongly associated with cirrhosis in CHB.Bo-An Li Jia Liu Jun Hou Jie Tang Jian Zhang Jun Xu Yong-Ji Song Ai-Xia Liu Jing Zhao Jing-Xia Guo Lin Chen Han Wang Li-Hua Yang Jie Lu Yuan-Li Mao 2015World Journal of Gastroenterology2015,21,1:11

18在胃的癌症的帮助 laparoscopy 对开的激进的 gastrectomy 的短期的功效显示文摘 AIM:To investigate the short-term benefits of laparoscopic radical gastrectomy(LARG)and open radical gastrectomy(ORG)in patients with gastric cancer.METHODS:A total of 400 patients with gastric cancer aged≤65 years who were treated at General Hospital of Lanzhou Military Region were enrolled.Among these,200 patients underwent LARG between October2008 and August 2012(LARG group);and 200 patients underwent ORG between March 2000 and September2008(ORG group).The short-term therapeutic benefits between the two groups were analyzed.RESULTS:The LARG procedure offered significantly better benefits to the patients compared to the ORG procedure,including less intraoperative blood loss(103.1±19.5 mL vs 163.0±32.9 mL,P<0.0001),shorter postoperative hospital stay(6.8±1.2 d vs 9.5±1.6 d,P<0.0001),less frequent occurrence of postoperative complications(6.5%vs 13.5%,P=0.02),shorter time to mobilization(1.0±0.3 vs 3.3±0.4 d,P<0.0001),shorter time to bowel opening(3.3±0.7 d vs 4.5±0.7 d,P<0.0001),and shorter time to normal diet(3.0±0.4 vs d 3.8±0.5 d,P<0.0001).However,LARG required a longer time to complete than the ORG procedure(192.3±20.9 min vs 180.0±26.9 min,P<0.0001).CONCLUSION:Compared to ORG,LARG is safer,more effective,and less invasive for treating gastric cancer,with better short-term efficacy.Hong-Tao Li Xiao-Peng Han Lin Su Wan-Kun Zhu Wei Xu Kun Li Qing-Chuan Zhao Hua Yang Hong-Bin Liu 2014World Journal of Gastrointestinal Surgery2014,6,4:10
19Effects of multidrug resistance, antisense RNA on the chemosensitivity of hepatocellular carcinoma cells显示文摘BACKGROUND: Multidrug resistance is a major obstacle in cancer chemotherapy. We examined whether the antisense RNA of multidrug resistance gene 1 (mdr1) could reverse multidrug resistance in the human hepatocellular carcinoma (HCC) cell line SMMC7721/ADM. METHODS: The recombinant adenoviruses pAdEasy- GFP-ASmdr1 product was produced by the adenoviral vector AdEasy system, which can express antisense RNA against the mdr1 gene. Following that, the recombinant adenovirus was transfected into the P-glycoprotein- producing multidrug resistance cell line, SMMC7721/ADM human HCC cells resistant to adriamycin (ADM) and daunorubicin (DNR). In order to investigate the reversal of multidrug resistance phenotype, we measured the expression of mdr1 mRNA by RT-PCR and the production of P-glycoprotein by flow cytometry. The sensitivities for ADM and DNR SMMC7721/ADM cells were examined by [3-(4, 5-dimethylthi-azol-2-yl)-2,5 diphenyl-terazolium bromide] (MTT) analysis. RESULTS: The low-level expression of mdr1 mRNA and P-glycoprotein production were observed in parental sensitive cells SMMC/7721 in addition to the overexpressionof mdr1 mRNA and P-glycoprotein in SMMC7721/ADM cells. The transfection of antisense-RNA into SMMC7721/ ADM cells resulted in decreases of mdr1 mRNA and P-glycoprotein, but increase of drug sensitivities. The sensitivities of transfected SMMC7721/ADM cells to ADM and DNR in IC50 reduced by 31.25% and 62.96% respectively. CONCLUSIONS: Mdr1 antisense RNA can increase the sensitivities of SMMC7721/ADM cells to anticancer drug by decreasing the expression of the mdr1 gene and inhibiting P-glycoprotein expression. This strategy may be applicable to cancer patients with P-glycoportein mediated multidrug resistance.Bo Li, Tian Ye, Lei Zhao, De-Hua Li, Xing-Hua Gou, Lan-Ying Zhao, Lei Han, Lin Chen, Lu-Nan Yan and Jian-Ping Gong Department of Hepatobiliary Surgery, Second Affiliated Hospital, Chongqing University of Medical Sciences, Chongqing 400010, China Department of Traditional Chinese Surgery, Second Affiliated Hospital, Luzhou Medical College, Luzhou 646000, China Genetic Engineering Laboratory, Chengdu Di’ao Group Co., Ltd., Chengdu 610041, China Department of General Surgery, West China Hospital, Sichuan University, Chengdu 610041, China 2006Hepatobiliary & Pancreatic Diseases International2006,5,4:10
20Complete genome sequence of the rifamycin SV-producing Amycolatopsis mediterranei U32 revealed its genetic characteristics in phylogeny and metabolism显示文摘Amycolatopsis mediterranei 被用于 rifamycin 的工业规模生产,它在 antimycobacterial 治疗起一个重要作用。作为类 Amycolatopsis 的首先定序的染色体, 236 715 底配对的包括 10 的紧张 U32 的染色体,最大的原核生物的染色体之一到目前为止曾经被定序。不同于在 streptomycetes 发现的线性拓扑学,这个染色体是圆形的,特别地类似于 Saccharopolyspora erythraea 和奴卡氏菌属 farcinica,在发展史和分类代表他们的靠近的关系。尽管在 A 预言了 9 228 编码蛋白质的基因。mediterranei 染色体 S 与那些分享了 orthologs 的最大的数字。erythraea,它被 Streptomyces coelicolor 而非 N 出人意料地跟随。farcinica,显示不同新陈代谢的特征经由改编演变到多样的生态的壁龛。除类似于那的一个核心区域以外在 streptomycetes 普通,有典型核心特征的一个新奇“伪核心”在非核心区域以内被定义,在 21 从 26 基因为第二等的代谢物生产聚类的总数被定位的地方。位于核心的 rifamycin 生合成基因簇为 rifamycin SV 的变换编码细胞色素 P450 酶必需品到 B,由比作 rifamycin 生产 B 紧张 S699 的高度相应的簇揭示了并且进一步由基因互补证实了。A 的 genomic 信息。mediterranei 表明在看起来复杂的规章的机制的控制下面不仅为各种各样的碳来源和无机的氮混合物的广泛的利用而且为新陈代谢的中介的有效 funneling 安排进第二等的抗菌素合成进程的一个新陈代谢的网络。Wei Zhao Yi Zhong Hua Yuan Jin Wang Huajun Zheng Ying Wang Xufeng Cen Feng Xu Jie Bai Xiaobiao Han Gang Lu Yongqiang Zhu Zhihui Shao Han Yan Chen Li Nanqiu Peng Zilong Zhang Yunyi Zhang Wei Lin Yun Fan Zhongjun Qin Yongfei Hu Baoli Zhu Shengyue Wang Xiaoming Ding Guo-Ping Zbao 2010Cell Research2010,20,10:10
