Cornea stroma mostly consists of proteins in extracellular matrix secreted by corneal epithelial cells,stroma and endothelial cells.A total of 1 679 unique Swiss-Prot annotated proteins are identified by LC-MS/MS analyses in human corneal stroma based on SDS-PAGE separation followed by in-gel trypsin digestion.As the principal component of corneal stroma, corneal stroma proteins play an important role in the physiological and pathological activities of eye.Studies towards their functions are helpful for revealing the pathogenesis of eye diseases and providing new ideas of prevention and therapy.Mainly through their manifestations,proteins in corneal stroma play a key role in forming gel-like organic material and network like structure of filaments.The gel-like organic material is composed of proteoglycan,enzymes,haemocyanin and binding proteins,while the network of filaments are constituted by collagen, elastin,keratin,vimentin as well as interconnected filaments made from fibronectin and laminin.The categories and functions of corneal stroma proteins were summarized.

Objective To compare the effectiveness and safety of radiofrenquency ablation(RFA) with other therapeutic methods for patients with early hepatocelluar carcinoma(HCC). Methods Randomized clinical trials(RCTs)which compared the efficacy or safety of RFA with other therapeutic methods for primary hepatocellular carcinoma in Cochrane library,EMBASE,PubMed,OVID and CBM were searched.Trials were considered of high quality if methodological quality score was 3 or more according to Jadad standard.Statistical heterogeneity between trials was evaluated bv STATA 9.0 and considered to exist when P＜0.1.Heterogeneity of the included articles was tested and used to select proper effective model for calculation.Sensitivity analysis was performed and publication bias was investigated through visual inspection of funnel plots and Egger regression model.Results Six RCTs including 862 cases were analyzed.As compared with other therapeutic approaches,RFA significandy increased 3-year overall survival rate and reduced local recurrence rate of early hepatocelluar carcinoma:the total OR were 2.06(95%CI being 1.54-2.77,P=0.000)and 0.40(95%CI being 0.28-0.57,P=0.000)respectively.As compared with other therapeutic approaches,the total OR of new HCC recurrence rates,extrahepatic metastasis rate and major complications in patients with HCC treated with RFA were 0.92 (95%CI being 0.68-1.24),0.98(95%CI being 0.30-3.22),1.35(95%CI being 0.49-3.77)respectively,showing no significant differences(P＞0.05).Inspection of the funnel plots for all outcome measures did not reveal evidence of publication bias(P=0.670,0.160,0.884,0.087,0.317,respectively,by Egger regression model).Conclusions RFA is superior to other treatment methods with respect to local recurrence and 3 year overall survival in early HCC and is the preferred tberapeutic method for small HCC because it is minimally invasive,simple and convenient.

Objective To study the relationship between endothel in-1 in plasma and TCD in patients with brain injury.Methods We measured dynamically the level of ET-1 in plasma on 33 adult brain injured patients. Cerebral vasospasm was detected by transcranal Doppler sonography (TCD).Results 1.During 6-8 days, 13-15 days after injury,there was a significantly positive correlation between the level of ET-1 in plasma and cerebral vasospasm (r=0.533,P=0.002;r=0.423,P=0.02),especially during 6-8 days after injury. The increase of the level of ET-1 in plasma paralleled paroled with the time of cerebral vasospasm developed. 2.During 6-8 days after injury, the level of ET-1 in plasma of patients with cerebral vasospasm was obviously higher than those without cerebral vasospasm obviously (P

Objective To evaluate the efficacy and safety of preoperative colonic stenting versus emergency surgery for acute left-sided malignant colonic obstruction based on literature. Methods The randomized clinical trials (RCT) on the subject were retrieved from PubMed,OVID,EMBASE,Cochrane library,CNKI,Wanfang data and VIP Chinese Scientific and Technologic Periodical Database.Statistical heterogeneity between trials was evaluated by Revman 5.0 and was considered to exist when P ＜ 0.1.Heterogeneity of the included articles was tested,which was used to select proper effect model.Publication bias was investigated through visual inspection of funnel plots.Results Five RCT including 283 cases were analyzed,in which 145 patients received preoperative colonic stenting and 138 received emergency surgery.Compared with those of emergency surgery groups,the total OR of permanent stoma,one-stage operation,and infection of preoperative colonic stenting group were 0.28 (95％ CI:0.12 - 0.62,P =0.002),2.13 (95 ％ CI:1.28 - 3.55,P =0.004) and 0.25 (95％ CI:0.08 - 0.80,P =0.02),respectively.There were no significant differences between 2 groups in anastomotic leakage,mortality,intra-abdominal infection,or overall morbidity.OR were 0.70 (95％ CI:0.29 - 1.71,P =0.44),1.17 (95％ CI:0.49 -2.79,P=0.72),0.27 (95％CI:0.03-2.65,P=0.26) and 0.32 (95％CI:0.07-1.42,P=0.13),respectively.Inspection of the funnel plots for all outcome measures did not reveal evidence of publication bias.Conclusion Preoperative colonic stenting significantly improves one-stage operation and decrease the rates of permanent stoma and wound infection.However,large-scale and high-quality RCTs are further needed.

Objective To evaluate the efficacy and safety of itopride in the treatment of functional dyspepsia (FD) according to the data of published clinical studies.Methods The papers about randomized controlled trials (RCT) of itopride in treatment of FD were searched from Cochrane library,EMBASE,PubMed,Elsevier,web of science (ISI),China national knonledge internet (CNKI),VIP Chinese Scientific and Technologic Periodical Database and Wanfang data,and the feature information in the studies were extracted.The relative risk (RR) value was used for count data and the weighted mean difference (WMD) was used for measurement data.The proper effect model was selected according to the results of heterogeneity test and the publication bias was investigated through visual inspection of funnel plots.Results A total of nine RCT met the inclusion standard.Of 2620 FD cases,1372 received itopride treatment and 1248 cases received placebo or other medicine as control treatment.The RR value of total effective rates,postprandial fullness and early satiety effective rates in itopride treated FD patients was 1.11 (95％CI:1.01,1.21; P=0.02),1.18 (95％CI:1.04,1.33; P=0.009),1.24 (95％CI:1.01,1.53; P=0.04),which showed the curative effects of itropride group were all better than those of control group.However there was no statistical significance in epigastric discomfort.The WMD of effective rates evaluated with the leeds dyspepsia questionnaire (LDQ) score was-1.38 (95％CI:-1.75,-1.01; P＜0.01),which showed the curative effect of itropride group was better than that of control group.For safety,the adverse effects rates of itopride groups were similar with control groups.The funnel plots of each inspection index presented wide bottom,narrow up and symmetrical graphics,which indicated that there was no publication bias.Conclusion Itopride has better efficacy in general symptoms,postprandial fullness,early satiety and LDQ score in FD patients,and few effects are detected.
