·AIM: To evaluate the recurrence rate and safety of amniotic membrane transplantation (AMT) augmented with mitomycin C (MMC) compared with amniotic membrane transplantation alone during the pterygium excision.·METHODS: We took a meta-analysis on this program.Pertinentstudieswereselectedthroughextensive searches of the Cochrane Library, MEDLINE, EMBASE,CBMdisc, CNKI. Pooled estimates were carried out in RevMan software V4.2.·RESULTS: Six trials reported postoperative recurrence rate of pterygium, included 882 eyes, three trials reported the complications. The results of meta-analysis showed that recurrence rate of AMT plus MMC group was 5.41％,AMT alone group was 16.89％, relative risk (RR) was 0.32, 95％CI ranged from 0.19 to 0.56, Zwas 4.06, P< 0.001. Two trials reported early complication as punctata keratitis, the incidence rate of AMT plus MMC group and AMT alone group were 17.14％ and 0.00％, RR was 12.11,95％CI ranged from 1.62 to 90.76.·CONCLUSION: Amniotic membrane transplantation with MMC is associated with lower recurrence rate compared with amniotic membrane transplantation alone in pterygium excision,whether accompanied a higher risk with adverse events need more investigation.

Objective To investigate the effects of injecting allogeneic mesenchymal stem cells(MSCs) on the cellular immunity in rat in vivo.Methods Bone marrow-derived MSCs were isolated from Wistar rats.The purity of MSCs was identified by morphological examination with microphotography,and the phenotypes were identified with flow cytometry.Twenty SD rats were randomly divided into 4 groups.Different concentrations of MSCs(5?106/ml for group A,5?105/ml for group B,and 5?104/ml for group C,respectively) and PBS(for group D) were given to allogeneic SD rats via intravenous infusions.The suppressive effect of MSCs on lymphocytes proliferation in recipient rat was analyzed using mixed lymphocyte cultures(MLR) 10 days after cultivation.At the same time,proportions of CD4+,CD8+ and CD4+CD25+/CD4+ T-lymphocytes in peripheral blood and spleen were analyzed with flow cytometry.Results Proliferation rate of splenic lymphocytes in group A(5?106/ml MSCs,8.58%?0.27%) was markedly lowered compared with that in group D(PBS,24.40%?5.21%,P

Objective To explore the value of dexamethasone(DEX) for neuronal cell injury and death by observing the effect of DEX on excitatory amino acid(EAA) and monoamine neurotransmitter in cerebral tissue of neonatal rat with hypoxia-ischemia.Methods Hypoxic-ischemic neonatal rat models were established,the levels of EAA and monoamine neurotransmitter in cerebral tissue were analyzed by using capillary electrophoresis and fluorospectrophotometry method.The rats were divided into 4 groups: small dose DEX group pre-treated with DEX(0.5 mg/kg) prior to hypoxia-ischemia,large dose DEX group pre-treated with DEX(10 mg/kg) prior to hypoxia-ischemia,HIE group and shamful operation group.Results The levels of EAA and monoamine neurotransmitter contents in HIE group were significantly higher than those in shamful operation group(P0.05).EAA contents of large dose DEX group greatly decreased compared with HIE group (P

Objective To discuss existing problems in talent team construction; To provide evidence for the government to enact proper strategies based on the analysis of the current situation of TCM practitioners (assistants) distribution in China from quantity, quality and distribution equity. Methods The research is studied through conducting a descriptive analysis of TCM practitioners (assistants) from quantity, education, job titles, ages, and other basic conditions and changes. Gini coefficient was used to evaluate the distribution of TCM practitioners (assistants). Results The quantity of TCM practitioners (assistants) increased by 53.7% from 2010 to 2015. Concerning the quality of personnel, the ratio of the personnel with bachelors degree or above increased from 38.6% to 44.2%, and a slight increase was observed with the personnel with senior title. In terms of age structure, the proportion of the age of TCM practitioners (assistants) under 25 years old, 35 to 59 years old decreased, and the proportion of the age of TCM practitioners (assistants) above 60 years old, 25 to 34 years old increased. From the perspective of equity, there is a difference between the provincial-level administration of human resources distribution. The Gini coefficient as per population distribution was around 0.1, which indicated good equity. From the geographical area configuration, the Gini coefficient was approximately 0.58, which showed high level of disparity. Conclusion There are problems of insufficient quantity, low quality and distribution disparity among regions in TCM practitioners (assistant) in China.

Objective To develop and evaluate the digital discrimination system for pancreatic ultrasound endoscopy images. Methods EUS images of 153 pancreatic cancer and 63 non-cancer cases were selected. According to the multi-fractal feature vectors based on the M-band wavelet transform, we acquired the fractal features with lower dimension with the feature screening algorithm. With the optimal feature combination, cases were classified into pancreatic cancer group and non-pancreatic cancer group automatically.Then the sensitivity, specificity and accuracy of this method were calculated, and compared with those of traditional 9 dimension fractal feature vectors. Results Three kinds of multi-fractal dimensions were introduced to the framework of M-band wavelet transform according to the EUS images to form fractal vectors of 18 dimension. With the selection by sequence forward search (SFS) algorithm, 7 dimension of feature vectors were chosen and were combined with bi-order multi-fractal dimension to a better feature combination. The Bayes, support vector machine (SVM) and ModestAdaBoost classifiers were introduced to evaluate the classification efficiency, resulting in a classification accuracy of 97.98% and short running time of 0. 49 s with lower feature dimension. Conclusion These data suggest the feasibility, accuracy, noninvasiveness and efficacy of classification of EUS images to differentiate pancreatic cancer from normal tissue based on the Mband wavelet transform algorithm. It is a new and valuable research area in diagnosis of pancreatic cancer.
