Objective To evaluate the efficacy of nucleos(t)ide analogues in patients with hepatitis B virus(HBV)-related chronic liver failure through Meta-analysis.Methods Literature search was done in Medline, PubMed, China National Knowledge Infrastracture(CNKI), Wanfang Database and China Biology Medicine(CBM)for papers published from 1990 to 2010 in Chinese or English, as well as the references in the relevant literature complemented by retrospective and manual literature search. Only literatures fully matching the inclusion and exclusion criteria could be included in this study. RavMan 5.0 statistical software was utilized for Meta-analysis. Then the sensitivity and publication bias about the data were measured by forest pl0t, funnel plot and fail-safe number. Results Total 1240 patients from 20 controlled clinical trials reported in Chinese and English papers were included in this study. The indicators of therapeutic efficacy were as below: HBV DNA undetectable rate relative risk(RR)=3. 37, 95％CI: 2. 20, 5. 16(Z=5. 60, P＜0. 01), prothrombin activity(PTA)weighted mean difference(WMD)=34.70, 95％CI: 25.62, 43.79(Z=7.49, P＜0.01), albumin(Alb)WMD=4.73, 95％ CI: 2.95, 6.51(Z=5.21, P＜0.01), alanine aminotransferase(ALT)WMD=42.58, 95％CI: -59.74, -25.41(Z=4.86, P＜0.01), total bilirubin(Tbil)WMD=-150.95, 95％CI: -199.29,-102.62(Z=6.12, P＜0.01), mortality RR=0. 55, 95％ CI: 0. 48, 0. 64(Z=8. 09, P＜0. 01). Conclusion Nucleos(t)ide analogues treatment could significantly increase HBV DNA undetectable rate, improve PTA and Alb, decrease levels of ALT and Tbil, which further reduces the short-term mortality of the patients with HBV-related chronic liver failure.

Objective To explore the effect of valproate(VPA) on body mass index(BMI),leptin and serum lipids in children with epilepsy.Methods (Twenty-)four cases with epilepsy were selected.BMI and serum levels of leptin,total cholesterol(TC),(triacylgly)-cerol(TG),high density lipoprotein-cholesterin(HDL-C),low density hipoprotein-cholesterin(LDL-C) after treated with VPA for 3 months and 6 months were determined.Results The levels of BMI,leptin,TC,TG,LDL-C after treated 3 months were all significantly higher than those of initial(all P0.05).Those in treated 6 months were same as levels of treated 3 months.Only LDL-C level was lower than that of 3 months and same as level of before treatment.Conclusion VPA do have efficacy to cause obesity in children with epilepsy,and most of the cases occur in the first 3 months after VPA treatment.

Objective To evaluate the effective of emergent endoscopic injection sclerotherapy ( EIS) for lethal bleeding from esophagogastric varices. Methods In this study, endoscopic injection of 5% sodium morrhuate was used to control esophagogastric variceal bleeding in 176 patients. In all 209 cases, 181 cases suffered from acute lethal bleeding from esophagogastric varices received endoscopic variceal sclerotherapy under the modified Senstaken-Blakemore tube compression. Results The exact bleeding site at the first procedure could be visualized in 166(94. 3% ) patients. The effective rate of EIS was 96. 2% . Multiple procedures were required in the 21 cases of relapsed bleeding. Complications of EIS occurred in 15 cases (8. 5% ) , of which 3(1. 7% ) died. Conclusion Endoscopic injection sclerotherapy under the modified Senstaken-Blakemore tube compression is relatively safe and effective procedure in the treatment of lethal bleeding from esophagogastric varices.

Purpose:To study the expressions of cyclin E and P53 in gastric carcinoma in relation to biological behavior and prognosis.Methods:Cyclin E and P53 expressions at protein level were determined by immunohistochemistry technique in 128 patients with gastric carcinoma.Results:Of the 128 patients , cyclin E positive expression was in 57(44 5%),P53 positive expression was in 67(52.3%),P53 and cyclin E were both positive in 48(37.5%),respectively.Cyclin E and P53 expression level were correlated with tumor size , invasion depth, regional lymph node status, vessel invasion, and distant metastasis, Univariate analysis demonstrated better survival in patients with negative cyclin E and P53 expressions than those with positive expression. By COX multivariate analysis, cyclin E expression level was found to be of independent prognostic significance, however p53 expression level was not found to be of independent prognostic significance.Conclusions:Cyclin E expression within gastric carcinoma tissues is an indicator of tumor behavior and prognosis, p53 expression within gastric carcinoma tissue is only an indicator of tumor behavior.

Objective To introduce the structure and operating principle of a laser optometer for dark focus(DF). Methods Infrared and vernier means were used in the examination of dark focus. The stability, relationship between dark focus and refractive error were studied. Results The laser optometer was proved to be a reliable instrument with fine stability and good repeatability. Conclusion The laser optometer for dark focus can be used for further study relating to the aviation vision.

To investigate the inherent characteristics of the pathogenic Yersinia enterocolitica. Polymerase chain reaction (PCR),analysis of DNA sequence,randomly amplified polymorphic DNA (RAPD) were used to study the pathogenic and nonpathogenic 10 strains of Yersinia enterocolitica. The Pathogenic Yersinia enterocolitica of serotyps 0∶3?0∶9 and 0∶5,27 were confirmed containing pathogenic gene of adherent invasion locus(ail) and their DNA fingerprints were much more similar,and it was also found that the serotype 0∶22 contained ail gene whose fingerprints was partly similar with the pathogenic ones in molecular structure. The pathogenic Yersinia enterocolitica strains were similar in the inherent and polymorphic. The serotype 0∶22 may have relativly evaluated association with pathogenic Yersinia enterocolitica, which is possible that it got potentially pathogenicity.

Ankylosing spondylitis (AS) is a systemic disease, which mainly causes to axial joint chronic inflammation. Spine, thoracic and peripheral joints may have varying degrees of activity limitation, and somatic activity is also likely to decline. Ankylosis of the spine and movement disorder of hip are the mainly causes of AS patients' disability, which not only affect the patients' motor function, and but also affect their social interaction, role affordability, mental state and daily living skills. Exercise therapy is the treatment unarmed or with equipment, for injuries, disease, residual patients, to restore or improve dysfunction. There are a number of studies about exercise therapy for joint function of patients with AS, confirmed that exercise therapy plays a crucial role in the treatment of AS patients, on the basis of the medications control.

Objective To ev aluate clinical results of selective anterior corpectomy combined with segmental discectomv and fusion for multilevel cervical myelopathv andits related factors.Methods Twenty-five patients of multilevel cervical myelopathv with 3 or 4 consecutive segments were treated with selective anterior corpectomy combinedwith segmental discectomy and fusion.The clinical results were evaluated by the parameters including improvement of Japanese Orthopaedic Association (JOA)score postoperatively,fusion rate,and the degree of spinal canal decompression and range of motion of the cervical spine.Results JOA score were improved from 9.5±1.3 pre-operatively to 13.8±0.8(P＜0.01)6 months post operation and 1 3.6±0.9(P＜0.05)atthe final follow-up.Bony fusion was verified by X-ray and 3D-CT scan 1 2 months post operation and final follow-up.Moreover,the degree of decompression of the spinal canal was also remarkable.The range of motion of the cervical spine after operation decreased significantly(P＜0.05).Conclusion Selective anterior corpectomy combined with segmental discectomy and fusion was an alternative choice for the surgical treatment of multilevel cervical myelopathy.
