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.

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.

Objective To systematically evaluate the efficacy and safety of green tea extract (GTE) in improving lipid metabolism in patients with metabolic syndrome (MS).Methods All relevant published articles in Chinese and English literature database were searched to collect the randomized controlled trials comparing the efficiency and safety of GTE in patients with MS.The meta-analysis was performed using RevMan 5.2 software.Results Nine studies involving 566 patients were included.The results of recta-analysis showed that:GTE significantly reduced the level of low-density lipoprotein cholesterol (LDL-C) (SMD =-0.33,95％ CI-0.56 ～ -0.09,P=0.007)compared with placebo at the treatment endpoint.There were no statistical significance in high-density lipoprotein cholesterol (SMD =0.19,95 ％ CI-0.04 ～ 0.43,P =0.10),total cholesterol (SMD =-0.13,95％ CI-0.39 ～ 0.13,P =0.33),and triglyceride (SMD =-0.07,95％ CI-0.46 ～ 0.33,P =0.74) levels between two groups.There was no significant difference in the overall rate of adverse events between two groups (OR =0.97,95 ％ CI 0.54 ～ 1.76,P =0.93).Conclusion GTE significantly reduces the level of LDL-C in patients with MS,and the adverse events were rare and mild.
