Objective To study the expression of Bcl-2 and E2F-1 in human adenomyosis and to explore the correlation between the expression and pathogenesis of human adenomyosis. Methods Immunohistochemical S-P method was employed to detect the expression of Bcl-2 and E2F-1 in 58 specimens of ectopic endometrium, eutopic endometrium of adenomyosis and 30 specimens of normal endometrium. Results The expression of Bcl-2 and E2F-1 in ectopic and eutopic endometrium of adenomyosis were significantly higher than those of normal endometrium (P

To investigate the seropharmacological action of Buyang Huanwu Decoction (BHD) on hypoxia induced apoptosis of cultured cortical neurons. Models of hypoxia induced neuron apoptosis were established by Daniel method. Neuron apoptotic rate was examined by propidium iodide staining method and flow cytometry, nitric oxide (NO) and malonyl dialdehyde (MDA) contents by spectrophotometer and bcl 2 gene expression by immunohistochemical method. Effects of BHD on neuron apoptotic rate, NO and MDA contents and bcl 2 gene expression were observed in normal group (Group A), model group (Group B), normal saline group (Group C) and high dosage, moderate dosage and low dosage BHD groups (Group D, Group E and Group F). BHD could inhibit the apoptosis of cultured cortical neurons, reduce the production of NO and MDA and promote the expression of bcl 2 gene.[Conclusion]BHD has an inhibitory effect on hypoxia induced apoptosis of cultured cortical neurons and its mechanism may be concerned with the reduction of NO and MDA production and the increase of bcl 2 gene expression.

Objective:To explore the factors influencing colonization of Mutans streptococci (MS) on teeth of children.Methods:Dental colonization of MS was investigated in 123 children aged from 7 to 42 months in Beijing. Oral examination was performed. Information of nursing habits, diet history etc. was obtained from parent questionnaires.Results:Logistic regression analysis showed that the number of erupted teeth and the intake of sugar-containing food were positively related with MS colonization, their WALD values were 17.411(P=0.000) and 5.637(P=0.018) respectively,OR values were 3.287 and 2.739 respectively.Conclusion:The main factors influencing the colonization of MS were the number of erupted teeth and the intake of sugar-containing food.

The authors discussed the retention and revision of the Regulations on the Handling of Medical Malpractice following the enforcement of the Tort Liability Law.These discussions also covered the amendment of the concept of medical malpractice,and the reforms to make on the medical malpractice appraisal system built upon the Regulations following the enforcement.In the meantime of applying the Law to judge cases of medical malpractice,the Regulations as an administrative regulations issued by the State Council,should be revised before playing its role in preventing medical malpractice,medical dispute handling,and penalising medical institutions and medical workers of malpractice.

Objective To assess the effects of radiofrequency ablation (RFA) and bipolar cord coagulation (BCC) on the prognosis and complication rate of complicated monochorionic twins.Methods A retrospective review was undertaken in 58 cases of complicated monochorionic twins treated with RFA or BCC at the First Affiliated Hospital of Sun Yat Sen University,from January 2008 to August 2013.Non-parametric Wilcoxon test,Chi-square test,Fisher exact test or multi-variant Logistic regression analysis were used for statistical analysis.Results Indications for selective termination in the 58 cases were:twin reversed arterial perfusion sequence in 12,severe twin to twin transfusion syndrome in 28,discordance of fetal anomalies in 10,selective intrauterine growth restriction in 7 and twin anemia-polycythemia sequence in 1.Forty-three cases were managed with BCC and 15 with RFA.Preterm labor was more common in the BCC group than in the RFA group [86.0％(37/43) vs 9/15,respectively; x2=4.598,P=0.032).Premature rupture of the membranes occurred in 48.8％(27/43) of the BCC group vs.4/15 of the RFA group (x2=2.229,P=0.135).The median procedure-todelivery time was 48 (1-150) days for the BCC group vs.101(14-138) days for the RFA group (Z=-2.245,P=0.025).Overall survival rate was 62.8％(27/43) in the BCC group vs 11/15 in the RFA group (x2=0.547,P=0.460),which was not significantly different.Neurodevelopmental delay was detected in two neonates in BCC group and in one neonate in RFA group.Logistic regression analysis showed that delivery before 28 gestational weeks was an independent risk factor for the poor prognosis of the co-twins (OR=192.720,95％CI:18.610-994.000,P ＜ 0.01).Conclusion Compared with BCC,RFA does not improve the prognosis of complicated monochorionic twins significantly.

Objective To investigate the scale and educational-level composition of nursing education in Guangdong Province,identify the issues in the development process,and provide suggestions accordingly.Methods Data on the scale and education level of nursing education were obtained from the Ministry of Education of China.Results Scale of nursing education at three levels for entering nursing (secondary diploma,advanced diploma,and baccalaureate degree) expanded rapidly during 2006～2010 in Guangdong,with 25.6 thousand recruitments totally in 2010,which as 2.05 times as in 2006.The portion of students recruited in secondary diploma programs had increased gradually,resulted in 83.53％ in 2010 (9.41％ for recruitments in advanced diploma programs and 7.06％ for baccalaureate degree programs).179 and 16 students were recruited in master's and doctoral programs in Guangdong,respectively,during 2006～ 2010.Conclusions The current scale and composition of nursing education in Guangdong should be improved according to the dynamic supply-need relationship of nursing workforce.Initial nursing education should be upgraded by increasing the recruitments of advanced diploma and baccalaureate programs and decreasing the recruitments of secondary diploma programs,expand graduate education,and ensure the quality of education.

Objective This study was designed to investigate the expression and clinical significance of transcription factor E2F-1 and apoptosis-off gene Bcl-2 in human colorectal carcinoma.Methods Immunohistochemistry is used to detect the expression of E2F-1、Bcl-2 proteins in 60 cases of human colorectal carcinoma tissues and their corresponding normal mucosa.Results The positive expression rate of E2F in cancer tissues is 56.7%,while the positive expression rate of E2F in corresponding normal mucosa is 6.7%,so the comparison between two tissues is significant (P

Objective To explore the effects of combined infusion of Treg cells from recipient rats and imDCs from donor rats prolonging the survival time of rats undergoing allogeneic orthotopic liver transplantation.Methods One hundred cases of rat allogeneic orthotopic liver transplantation were performed by using modified two-cuff method: DA rats served as donors,and Lewis rats as recipients,which were divided into 5 groups: acute rejection group,mDC group,imDC group,Treg group,co-infusion group (imDC-Treg group).2 × 106 imDC,2 × 106 mDC and 1 × 107 Treg cells were respectively injected to Lewis rats in every group via caudal vein before transplantation.Four Lewis rats from each group were randomly sacrificed on the day 3,7 and 10 after transplantation.Liver function (ALT and TBIL) and changes of cytokines (IL-10,IL-2 and TGF-β) were evaluated in peripheral blood.The pathological changes of the liver graft were observed.The DNA fragmentation characteristics of apoptosis in the liver were detected by using TUNEL staining.Survival analysis was performed on remnant rats.Results The liver function in imDC-Treg group had reverted to normal faster than that in the control groups.ELISA revealed that at day 7,the serum levels of IL-10 and TGF-β were higher,and the serum levels of IL-2 were lower in imDC-Treg group.Liver pathology demonstrated that there was only a slight number of mononuclear cell infiltration in hepatic graft afterorthotopic liver transplantation in co-infusion group (imDC-Treg group),which belonged to a nonidentified or slight type of acute rejection,and the liver graft showed regeneration of hepatocytes along with a small number of neutrophile granulocyte infiltration at the day 10.TUNEL staining indicated that the number of apoptotic T cells was much less in control groups than in imDC-Treg groups.The survival time of recipients in Treg-imDC group was 37 days,significantly longer than in irnDC group (23 days) and Treg group (15 days).Conclusion Infusion of imDC from donor rats or Treg from recipient rats alone couldn't induce long-term allograft survival of recipients after allogeneic rat liver transplantation.The co-infusion of Treg and imDC significantly prolonged the survival time of rats subject to allogeneic liver transplantation.
