Objective To systematically evaluate the efficacy of green tea extract (GTE) on weight control in metabolic syndrome (MS).Methods Related randomized controlled trials (RCTs) about GTE and MS were searched and identified from PubMed,Scopus,PsycINFO,EMBase,the VIP database,CNKI,and Wanfang Resource Database.Valid data were extracted according to strict inclusion and exclusion criteria.The RevMan 5.2.2 software was used to carry out the meta-analysis.Results A total of 10 trials involving 626 patients were ultimately included.Meta analysis showed that:1) compared with the placebo group,body weight (SMD=0.19,95% CI-0.34 to-0.03,Z 2.34,P=0.02) and waist circumference (SMD=-0.19,95%CI-0.36 to-0.02,Z=2.15,P=0.03) were significantly decreased in the GTE group;2) no significant difference was found between the two groups in BMI (SMD=0.14,95% CI-0.31 to 0.03,Z=1.63,P=0.10),hip circumference (SMD=0.15,95%CI-0.11 to 0.42,Z=1.12,P=0.26) or waist-to-hip ratio (WMD=-0.02,95%CI-0.05 to 0.01,Z=1.32,P=0.19).Conclusions Green tea extract can significantly reduce body weight and waist circumference in patients with metabolic syndrome.

Objective To discuss method,operative characters and curative effect of total hip arthroplasty(THA)in treatment of acetabular fractures combined with ipsilateral femoral head or neck fractures.Methods One stage THA was done in seven patients with acetabular fractures combined with ipsilateral femoral head fracture(one patient)or femoral neck fractures(six patients)7-21 days after fractures.There were five males and two females,at age range of 41-65 years(average 50 years).According to AO classification,there were one patient with type A fracture,three with type B and three with type C.Of all,five patients received biological acetabular replacement after reduction and internal fixation of acetabular fracture and two received PMMA acetabular replacement with metal enforcement ring.All patients received biological femoral stem.Results Of all,six patients were followed up for from 2 years and 3 months to 6 years and 5 months(mean 3 years and 9 months),which showed heterotopic ossitlcation in one patient and dislocation in one who recovered after manipulative reduction.The Harris score was increased from mean prooperative 48 points to mean postoperative 91 points.X-ray found no loosening of prosthesis during follow-up.Conclusions THA can improve function of hip joint significantly,avoid further operation and lessen the burden of patients mentally and economically and hence is effective in treatment of acetabular fracture combined with ipsilateral femoral head or neck fractures.

AIM: Apply the newly invented method of suppression subtractive hybridization to scan the mitochondria genes expression of hippocampus neurons in post ischemia/reperfusion rats. METHODS: Decapitate the rats suffering 10 min of whole brain ischemia and 24 h of reperfusion in Pulsinelli’s 4 vessels occlusion ischemia/reperfusion model. Dissociated hippocampus and isolated mRNA. After reversed transcription, use SSH to subtract the common sequences, then use suppressed PCR to amplify the differentially expressed sequences. After cloning and DNA sequencing, the dot hybridization was used to finally identify the differential gene expression. RESULTS: In the 78 positive clones acquired from cloning, 7 clones represent differential gene expression after confirmed by clone PCR, dot blot and DNA sequencing. The DNA sequencing data indicate these clones are ESTs of Cytochrome c oxidase subunit and NADH-ubiquinone oxidoreductase chain 4 gene. CONCLUSION: Cytochrome C oxidase mRNA level changs during brain ischemia /reperfusion. The differential expression of NADH-ubiquinone oxidoreductase chain 4, one of those 13 subunits of subcomplex ?, suggests that subcomplex ? may have important function associated with pathophysiologic changs in reperfusion injury.

Background Dry eye is the most common ocular surface disease.Anterior segment pattern of optical coherent tomography (OCT) is able to be used to assess the tear meniscus directly and accurately.Objective This study was to evaluate the correlation between measuring outcomes of tear meniscus by anterior segment module of OCT with signs and symptoms of dry eye.Methods A retrospective serial cases-observational study was designed.Thirty-six patients who completed Ocular Surface Disease Index (OSDI) and got a score more than 20 were enrolled in the First Hospital of Peking University from September to October,2010 under the informed consent.The upper and lower tear meniscus height (U/LTMH,μm),depth (U/LTMD,μm) and cross sectional area (U/LMA,mm2) were measured with the anterior segment module of OCT (RTVue.pitch).A series of clinical tests were performed,including tear film interferometry,break-up time (BUT),fluorescein corneal staining,lissamine green conjunctival staining and Schirmer Ⅰ test (S Ⅰ t).The correlations of measuring outcomes of tear meniscus by anterior segment module of OCT with dry eye-related examinations were analyzed with Spearman correlation coefficients.Results The values of UTMH,UTMD,UMA were (232±56) μm,(156±53) μm,(0.021 ±0.008) mm2,respectively,and the values of LTMH,LTMD,LMA were (222 ± 72) μm,(163 ± 65) μm,(0.020 ± 0.006) mm2,respectively.No significant differences were found in the measuring values between the upper and the lower tear meniscus (all at P>0.05).The quantitative values of tear meniscus were not significantly correlated with the OSDI scores or tear film interferometry grade.Significant correlations were seen between UTMH,UTMD,UMA and BUT (r=0.46,P=0.01 ;r=0.40,P=0.02;r=0.43,P=0.01).LTMH,LTMD,LMA were positively correlated with BUT (r=0.61,P=0.00;r=0.64,P=0.00;r=0.64,P=0.00) and S Ⅰ t (r=0.54,P=0.02 ;r=0.46,P=0.01;r=0.55,P=0.01) as well as negatively correlated with fluorescein cornealstaining (r=-0.37,P=0.04;r=-0.37,P=0.04;r=-0.41,P =0.05) and lissamine green conjunctival staining (r =-0.56,P =0.01 ; r =-0.37,P =0.04 ; r =-0.47,P =0.00).Conclusions Anterior segment module of OCT is an effective approach to the measurement of tear meniscus.The measuring outcomes of anterior segment of OCT are associated with dry eye-related signs.
