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

·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 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 evaluate the effect of hyperbaric oxygen therapy (HBOT) in patients with severe traumatic brain injury (STBI) after craniotomy,and evaluate the difference of HBOT effects on the patients whose Glasgow coma score (GCS) were 6-8 scores and 3-5 scores.Methods Using case-control study,61 neurosurgical in-patients with STBl from February 6,2009 to November 25,2010 were divided into two groups by random digits table,30 in HBOT group and 31 in control group.Their GCS at the periods on admission,before HBOT and when they finished HBOT were recorded,as well as the Glasgow outcome score (GOS) before HBOT,finished HBOT,and 3 months after admission (GOS3M).Results The GCS finished HBOT were (12.63 ±2.70) scores in HBOT group and (11.64 ±2.50) scores in GCS 3-5 subgroup,there were statistically differences than those in control group [ (10.61± 3.01 ),(8.44 ± 1.67)scores] (P ＜0.05).The mean rank of GCS finished HBOT improvement (△GOSf) and GOS scores 3months after admission ( △ GOS3M) in HBOT group was 35.37 and 35.87,which were significantly higher than those in control group (26.77 and 26.29) (P ＜0.05).Meanwhile,the mean rank of △GOSf and △ GOS3M in GCS 3-5 subgroup was 12.14 and 13.09,which were significantly higher than those in control group (8.05 and 7.33) (P ＜ 0.05 ).In GCS 6-8 subgroup,there was no significant difference in △ GOSf and △ GOS3M between HBOT group and control group (P ＞ 0.05).Conclusion Early HBOT is effective to improve the recovery of consciousness and prognosis of the postoperative patient with STBI,especially of the patients with the special STBI (GCS 3-5 scores ).

Background The condition of the sclera is associated with many ocular diseases.The measurement of human scleral thickness in vivo is helpful for us to understand the features of the sclera and related diseases.Objective The present study was to measure the anterior sclera thickness(AST) in patients with senile cataract and to analyze the relationship among AST and other associated ocular parameters.Methods This study was approved by the Ethic Commission of First Hospital of Peking University.Written informed consent was obtained from each individual prior to examination.One hundred and five senile cataract patients were recruited in this study.Central corneal thickness (CCT),corneal curvature (CCV) and axial length were measured using ultrasonic pachymeter,keratometer,and A-scan unit,respectively.The AST was measured at 2 mm posterior to the scleral spur in the temporal meridian using ultrasound biomicroscope (UBM).The differences of CCT,CCV,ocular axial length and AST between bilateral eyes and the different sexes were compared by the Paired test and independent sample t test.The correlations among various parameters were assessed by the Pearson linear correlation analysis.The differences of CCT and AST among different axial length groups were evaluated by one-way ANOVA.Results No significant differences were found in the CCT,CCV,axial length and AST between bilateral eyes (t =0.584,P =0.561 ; t =1.161,P =0.248 ; t =0.140,P =0.889 ; t =0.342,P =0.773).Temporal AST at 2 mm posterior to the sclera spur was (0.589 ±0.051)mm in the right eyes.An insignificant decline in CCT was found in the male group compared with the female group (right eyes:t =0.469,P =0.641 ; left eyes:t =0.465,P =0.643).However,compared with the female group,the increase of axial length,reduction of the mean CCV value and enhancement of the mean AST were observed(right eyes:all P＜0.01 ;left eyes:all P＜0.01).CCV showed a negative correlation with ocular axial length (r =-0.50,P＜0.01),but no significant correlation was found among age,CCT,ocular axial length and AST(P＞0.05).No remarkable differences were found in CCT and AST among the various axial length groups (CCT:F =0.998,P=0.372;AST:F=1.919,P=0.383).Conclusions In senile cataract patients,correlation is not found between AST and CCT;the increase of axial length is not associated with the thinning of the eyeball wall to a certain extent.Differences exist in some ocular parameters between different sexes.
