32018 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
4Indicators of prognosis after liver transplantation in Chinese hepatocellular carcinoma patients显示文摘AIM: To identify prognostic factors of patients with hepatocellular carcinoma (HCC), who were treated by orthotopic liver transplantation (OLT). METHODS: From January 2000 to October 2006, 165 patients with HCC underwent OLT. Various clinicopathological risk factors for actuarial and recurrence-free survival were identified using the Kaplan-Meier method with the log-rank test. The Cox proportional hazards model was used to identify independently predictive factors for actuarial and recurrence-free survival, which were used to propose new selection criteria. We compared the outcome of the subgroup patients meeting different criteria. Survival analysis was performed using the Kaplan-Meier method with the log-rank test. RESULTS: The median follow-up was 13.0 mo (2.8-69.5 mo). Overall, 1-, 2-, 3-and 5-year actuarial survival was 73.3%, 45.6%, 35.4% and 32.1%, respectively. One-, 2-, 3-and 5-year overall recurrencefree survival was 67.0%, 44.3%, 34.5% and 34.5%, respectively. In univariate analysis, number of tumors, total tumor size, lobar distribution, differentiation, macrovascular invasion, microvascular invasion, capsulationof the tumor, and lymph node metastasis were found to be associated significantly with actuarial and tumor-free survival. By means of using the multivariate Cox proportional hazards model, total tumor size and macrovas-cular invasion were found to be independent predictors of actuarial and tumor-free survival. When the selection criteria were expanded into the proposed criteria, there was no significant difference in 1-, 2-, 3-and 5-year actuarial and tumor-free survival of the 49 patients who met the proposed criteria (97.6%, 82.8%, 82.8% and 82.8%, and 90.7%, 82.8%, 68.8% and 68.8%, respectively) compared with that of patients who met the Milan or University of California, San Francisco (UCSF) criteria. CONCLUSION: Macrovascular invasion and total tumor diameter are the strongest prognostic factors. The proposed criteria do not adversely affect the outcome of liver transplantation for HCC, compared with the Milan or UCSF criteria.Jin Li Lu-Nan Yan Jan Yang Zhe-Yu Chen Bo Li Yong Zeng Tian-Fu Wen Ji-Chun Zhao Wen-Tao Wang Jia-Yin Yang Ming-Qing Xu Yu-Kui Ma 2009World Journal of Gastroenterology2009,15,33:37
5Facile Synthesis and Application of Ag-Chemically Converted Graphene Nanocomposite显示文摘An in situ chemical synthesis approach has been employed to prepare an Ag-chemically converted graphene (CCG) nanocomposite. The reduction of graphene oxide sheets was accompanied by generation of Ag nanoparticles. The structure and composition of the nanocomposites were confirmed by means of transmission electron microscopy (TEM), atomic force microscopy (AFM) and X-ray diffraction. TEM and AFM results suggest a homogeneous distribution of Ag nanoparticles (5-10 nm in size) on CCG sheets. The intensities of the Raman signals of CCG in such nanocomposites are greatly increased by the attached silver nanoparticles, i.e., there is surface-enhanced Raman scattering activity. In addition, it was found that the antibacterial activity of free Ag nanoparticles is retained in the nanocomposites, which suggests they can be used as graphene-based biomaterials.Jianfeng Shen Min Shi Na Li Bo Yan Hongwei Ma Yizhe Hu Mingxin Ye 2010Nano Research2010,3,5:29

9Clinical study on safety of adult-to-adult living donor liver transplantation in both donors and recipients显示文摘AIM: To investigate the safety of adult-to-adult living donor liver transplantation (A-A LDLT) in both donors and recipients. METHODS: From January 2002 to July 2006, 50 cases of A-A LDLT were performed at West China Hospital, Sichuan University, consisting of 47 cases using right lobe graft without middle hepatic vein (MHV), and 3 cases using dual grafts (one case using two left lobe, 2 using one right lobe and one left lobe). The most common diagnoses were hepatitis B liver cirrosis, 30 (60%) cases; and hepatocellular carcinoma, 15 (30%) cases in adult recipients. Among them, 10 cases had the model of end-stage liver disease (MELD) with a score of more than 25. Donor screening consisted of reconstruction of the hepatic blood vessels and biliary system with 3-dimension computed tomography and volumetry of whole liver and right liver volume. Various improved surgical techniques were adopted in the procedures for both donors and recipients . RESULTS: Forty-nine right lobes and 3 left lobes (2 left lobe grafts for 1 recipient, 1 left lobe graft for 1 recipient who had received right lobe graft donated by relative living donor) were obtained from 52 living donors. The 49 right lobe grafts, without MHV, weighed 400 g-850 g (media 550 g), and the ratio of graft volume to recipient standard liver volume (GV/SLV) ranged from 31.74% to 71.68% (mean 45.35%). All donors' remnant liver volume was over 35% of the whole liver volume. There was no donor mortality. With a follow-up of 2-52 mo (media 9 mo), among 50 adult recipients, complications occurred in 13 (26%) cases and 4 (8%) died postoperatively within 3 mo. Their 1-year actualsurvival rate was 92%. CONCLUSION: When preoperative CT volumetry shows volume of remnant liver is more than 35%, the ratio of right lobe graft to recipients standard liver volume exceeding 40%, A-A LDLT using right lobe graft without MHV should be a very safe procedure for both donors and recipients, otherwise dual grafts liver transplantation should be considered.Bin Liu Lu-Nan Yan Wen-Tao Wang Bo Li Yong Zeng Tian-Fu Wen Ming-Qing Xu Jia-Yin Yang Zhe-Yu Chen Ji-Chun Zhao Yu-Kui Ma Jiang-Wen Liu Hong Wu 2007World Journal of Gastroenterology2007,13,6:17
10Blocking FSH inhibits hepatic cholesterol biosynthesis and reduces serum cholesterol显示文摘Menopause is associated with dyslipidemia and an increased risk of cardio-cerebrovascular disease.The classic view assumes that the underlying mechanism of dyslipidemia is attributed to an insufficiency of estrogen.In addition to a decrease in estrogen, circulating follicle-stimulating hormone (FSH)levels become elevated at menopause.In this study,we find that blocking FSH reduces serum cholesterol via inhibiting hepatic cholesterol biosynthesis.First,epidemiological results show that the serum FSH levels are positively correlated with the serum total cholesterol levels,even after adjustment by considering the effects of serum estrogen,in addition,the prevalence of hypercholesterolemia is significantly higher in peri-menopausal women than that in premenopausal women.Furthermore,we generated a mouse model of FSH elevation by intraperitoneally injecting exogenous FSH into ovariectomized (OVX)mice,in which a normal level of estrogen (E2)was maintained by exogenous supplementation. Consistently,the results indicate that FSH,independent of estrogen,increases the serum cholesterol level in this mouse model. Moreover,blocking FSH signaling by anti-FSHβ antibody or ablating the FSH receptor (FSHR)gene could effectively prevent hypercholesterolemia induced by FSH injection or high-cholesterol diet feeding.Mechanistically,FSH,via binding to hepatic FSHRs, activates the Gi2α/β-arrestin-2/Akt pathway and subsequently inhibits the binding of FoxO1 with the SREBP-2 promoter,thus preventing FoxO1 from repressing SREBP-2 gene transcription.This effect,in turn,results in the upregulation of SREBP-2,which drives HMGCR nascent transcription and de novo cholesterol biosynthesis,leading to the increase of cholesterol accumulation.This study uncovers that blocking FSH signaling might be a new strategy for treating hypercholesterolemia during menopause, particularly for women in peri-menopause characterized by FSH elevation only.Yanjing Guo Meng Zhao Tao Bo Shizhan Ma Zhongshang Yuan Wenbin Chen Zhao He Xu Hou Jun Liu Zhenhai Zhang Qiang Zhu Qiangxiu Wang Xiaoyan Lin Zhongli Yang Min Cui Lu Liu Yujie Li Chunxiao Yu Xiaoyi Qi Qian Wang Haiqing Zhang Qingbo Guan Lifang Zhao Shimeng Xuan Huili Yan Yanliang Lin Li Wang Qihang Li Yongfeng Song Ling Gao Jiajun Zhao 2019Cell Research2019,29,2:16
11COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented.Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu 2021China CDC weekly2021,3,21:16
12Radiofrequency ablation for hepatic hemangiomas: A consensus from a Chinese panel of experts显示文摘Recent studies have shown that radiofrequency(RF) ablation therapy is a safe, feasible, and effective procedure for hepatic hemangiomas, even huge hepatic hemangiomas. RF ablation has the following advantages in the treatment of hepatic hemangiomas: minimal invasiveness, definite efficacy, high safety, fast recovery, relatively simple operation, and wide applicability. It is necessary to formulate a widely accepted consensus among the experts in China who have extensive expertise and experience in the treatment of hepatic hemangiomas using RF ablation, which is important to standardize the application of RF ablation for the management of hepatic hemangiomas, regarding the selection of patients with suitable indications to receive RF ablation treatment, the technical details of the techniques, therapeutic effect evaluations, management of complications, etc. A final consensus by a Chinese panel of experts who have the expertise of using RF ablation to treat hepatic hemangiomas was reached by means of literature review, comprehensive discussion, and draft approval.Jun Gao Rui-Fang Fan Jia-Yin Yang Yan Cui Jian-Song Ji Kuan-Sheng Ma Xiao-Long Li Long Zhang Chong-Liang Xu Xin-Liang Kong Shan Ke Xue-Mei Ding Shao-Hong Wang Meng-Meng Yang Jin-Jin Song Bo Zhai Chun-Ming Nin Shi-Gang Guo Zong-Hai Xin Jun Lu Yong-Hong Dong Hua-Qiang Zhu Wen-Bing Sun 2017World Journal of Gastroenterology2017,23,39:15
13Effects of mulberry leaf flavonoid and resveratrol on methane emission and nutrient digestion in sheep显示文摘As a new type of methane control agent, natural plant extract has been widely studied in recent years,but in vivo studies are few. This study was to investigate the effects of the dietary supplementation of 2 different polyphenols on the methane(CH4) emission and digestion metabolism in sheep. Ten healthy crossbred sheep(Dorper(?)× small-tailed Han ♀; BW 60.0 ± 1.73 kg) were used in a change-over design.The sheep were fed the following 3 diets in the present study: the basal diet(CON) with no supplementation; the basal diet supplemented with 2 g mulberry leaf flavonoid(MLF) per day per sheep; the basal diet supplemented with 0.25 g resveratrol(RES) per day per sheep. Both MLF and RES reduced CH4 emission scaled to metabolic weight per kilogram of DMI and CO2 output scaled to metabolic weight, but the effect of RES was significant(P < 0.05). Both MLF and RES significantly improved apparent digestibility of DM, OM, NDF, ADF, and nitrogen, but the effect of RES was significant(P < 0.05). Both MLF and RES significantly improved ME(P < 0.05) and reduced energy losses in CH4 emission(P > 0.05). In conclusion, MLF and RES can improve the digestibility of nutrients, the utilization of nutrients and energy, and reduce CH4 emission, but they are not conducive to nitrogen retention.Dandan Chen Xiaolin Chen Yan Tu Bo Wang Can Lou Tao Ma Qiyu Diao 2015Animal Nutrition2015,,4:14
14Risk factors associated with early and late HAT after adult liver transplantation显示文摘AIM:To identify risk factors that might contribute to hepatic artery thrombosis(HAT)after liver transplantation(LT).METHODS:The perioperative and follow-up data of a total of 744 liver transplants,performed from February1999 to July 2010,were retrospectively reviewed.HAT developed in 20 patients(2.7%).HAT was classified as early(occurring in fewer than 30 d post LT)or late(occurring more than 30 d post LT).Early HAT developed in 14 patients(1.9%).Late HAT developed in 6patients(0.8%).Risk factors associated with HAT were analysed using theχ2 test for univariate analysis and logistic regression for multivariate analysis.RESULTS:Lack of ABO compatibility,recipient/donor weight ratio≥1.15,complex arterial reconstruction,duration time of hepatic artery anastomosis>80 min,duration time of operation>10 h,dual grafts,number of units of blood received intraoperatively≥7,number of units of fresh frozen plasma(FFP)received intraoperatively≥6,postoperative blood transfusion and postoperative FFP use were significantly associated with early HAT in the univariate analysis(P<0.1).After logistic regression,independent risk factors associated with early HAT were recipient/donor weight ratio≥1.15(OR=4.499),duration of hepatic artery anastomosis>80 min(OR=5.429),number of units of blood received intraoperatively≥7(OR=4.059)and postoperative blood transfusion(OR=6.898).Graft type(whole/living-donor/split),duration of operation>10 h,retransplantation,rejection reaction,recipients with diabetes preoperatively and recipients with a high level of blood glucose or diabetes postoperatively were significantly associated with late HAT in the univariate analysis(P<0.1).After logistic regression,the independent risk factors associated with early HAT were duration of operation>10 h(OR=6.394),retransplantation(OR=21.793)and rejection reactions(OR=16.936).CONCLUSION:Early detection of these risk factors,strict surveillance protocols by Doppler ultrasound and prophylactic anticoagulation for recipients at risk might be determined prospectively.Yi Yang Ji-Chun Zhao Lu-Nan Yan Yu-Kui Ma Bin Huang Ding Yuan Bo Li Tian-Fu Wen Wen-Tao Wang Ming-Qing Xu Jia-Yin Yang 2014World Journal of Gastroenterology2014,20,30:13
15Liver transplantation for patients with hepatolithiasis显示文摘Because of its complicated pathological features such as repeated cholangitis and multiple operations, hepatolithiasis is difficult to treat and often lead to portal hypertension, and liver failure. The aim of this study was to investigate the indications of orthotopic liver transplantation ( OLT) for patients with hepatolithiasis and the improvement of operative techniques and the treatment of postoperative complications. METHODS:The data of 4 patients with hepatolithiasis who had undergone OLT at our department in recent years were reviewed retrospectively. RESULTS:The 4 patients with hepatolithiasis complicated with secondary biliary cirrhosis in end-stage liver disease included 1 woman and 3 men. One patient underwent OLT using veno-venous bypass prior to the mobilization of the liver. Two patients were subjected to liver transplantation with improved piggyback technique without bypass. One patient received OLT without bypass. All patients were operated on successfully and recovered uneventfully. Patient 1 had bleeding from the digestive tract on the postoperative day 6. Patient 2 had hemorrhage from the digestive tract and a leakage of end-to-side intestinal anastomosis on the postoperative day 44. Patient 4 was reoperated on because of hemorrhage from the anastomotic stoma of the hepatic artery on the postoperative days 8 and 10. In the 4 patients the mean operative time was 7.9 hours and blood loss was 910 ml. Postoperative pathological analysis revealed biliary liver cirrhosis. Follow-up of all patients showed good conditions. CONCLUSIONS:Hepatolithiasis with secondary biliary liver cirrhosis in patients with end-stage liver disease is indicated for liver transplantation. Veno-venous bypass prior to the mobilization of the liver and improved piggyback tech- nique can lower the incidence of intraoperative bleeding, the duration of surgery and postoperative complications.Guang-Dong Pan, Lu-Nan Yan, Bo Li, Shi-Chun Lu, Yong Zeng, Tian-Fu Wen, Ji-Chun Zhao, Nan-Sheng Cheng, Yu-Kui Ma, Wen-Tao Wang, Jia-Yin Yang and Zhi-Hui Li Center of Liver Transplantation, West China Hospital, Sichuan University, Chengdu 610041 , China 2005Hepatobiliary & Pancreatic Diseases International2005,4,3:13
16Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12

Human lens epithelial cell line(SRA01/04) cells were transfected with either miR-211 mimics, mimic controls, miR-211 inhibitors or inhibitor controls, 72 h after transfection, miR NA and protein expression of SIRT1 were measured using RT-qP CR and Western blotting; then cells were exposed to 200 μmol/L H_2O_2 for 1h, whereupon cell viability was measured by MTS assay, caspase-3 assay was performed. Dual luciferase reporter assay was performed to verify the relationship between miR-211 of SIRT1.RESULTS: Compared to the control group, expression of miR-211 was significantly increased(P<0.001), the miR NA and protein expression of SIRT1 were significantly decreased(P<0.001) in the anterior lens capsules of patients with age-related cataracts. Relative to the control group, SIRT1 miR NA and protein levels in the miR-211 mimic group were significantly reduced, cell proliferation activity significantly decreased, and caspase-3 activity was significantly increased(P<0.001). In the miR-211 inhibitor group, SIRT1 miRNA and protein expression were significantly increased, cell proliferation activity significantly increased, and caspase-3 activity was significantly decreased(P<0.001). A dual luciferase reporter assay confirmed that SIRT1 is a direct target of miR-211.CONCLUSION: miR-211 is highly expressed in the anterior lens capsules of patients with age-related cataracts. By negatively regulating the expression of SIRT1, miR-211 promotes lens epithelial cell apoptosis and inhibits lens epithelial cell proliferation.Bo Lu Ian T.Christensen Li-Wei Ma Xin-Ling Wang Ling-Feng Jiang Chun-Xia Wang Li Feng Jin-Song Zhang Qi-Chang Yan 2018International Journal of Ophthalmology(English edition)2018,11,2:10

20Focal adhesion protein Kindlin-2 regulates bone homeostasis in mice显示文摘Our recent studies demonstrate that the focal adhesion protein Kindlin-2 is critical for chondrogenesis and early skeletal development. Here, we show that deleting Kindlin-2 from osteoblasts using the 2.3-kb mouse Col1 a1-Cre transgene minimally impacts bone mass in mice, but deleting Kindlin-2 using the 10-kb mouse Dmp1-Cre transgene, which targets osteocytes and mature osteoblasts, results in striking osteopenia in mice. Kindlin-2 loss reduces the osteoblastic population but increases the osteoclastic and adipocytic populations in the bone microenvironment. Kindlin-2 loss upregulates sclerostin in osteocytes,downregulates β-catenin in osteoblasts, and inhibits osteoblast formation and differentiation in vitro and in vivo. Upregulation ofβ-catenin in the mutant cells reverses the osteopenia induced by Kindlin-2 deficiency. Kindlin-2 loss additionally increases the expression of RANKL in osteocytes and increases osteoclast formation and bone resorption. Kindlin-2 deletion in osteocytes promotes osteoclast formation in osteocyte/bone marrow monocyte cocultures, which is significantly blocked by an anti-RANKLneutralizing antibody. Finally, Kindlin-2 loss increases osteocyte apoptosis and impairs osteocyte spreading and dendrite formation.Thus, we demonstrate an important role of Kindlin-2 in the regulation of bone homeostasis and provide a potential target for the treatment of metabolic bone diseases.Huiling Cao Qinnan Yan Dong Wang Yumei Lai Bo Zhou Qi Zhang Wenfei Jin Simin Lin Yiming Lei Liting Ma Yuxi Guo Yishu Wang Yilin Wang Xiaochun Bai Chuanju Liu Jian QFeng Chuanyue Wu Di Chen Xu Cao Guozhi Xiao 2020Bone Research2020,8,1:8
