Objectives To evaluate the mechanism of mitral regurgitation after mitral valve surgery by quantitative assessment of mitral valve three-dimensional parameters using real-time three-dimensional echocardiography (RT-3DE). Me-thods According to the improved degree of mitral regurgitation (MR), 30 children were divided into two groups after mitral valve repair:MR improved (I) group and residual MR (II) group. And the pre-operative 3-DE parameters were compared with post-operative parameters in two groups respectively. Results In group I, three dimensional parameters, including mitral valve annular area in end-systole and end-dilate (AA1, AA2), PM papillary muscle annular distance (AL-A), AL papillary muscle annular distance (PM-A), inter-papillary distance (PM-AL), the anterior leaflet and posterior leaflet tethering angles (a1, a2, argAL-C-PM), left ventricular volume end-systole and end-dilate (LVEDV, LVESV) were significantly improved after surgery (P<0.05) while the parameters PM-A, PM-AL, argAL-C-PM, LVEDV, LVESV and left ventricular ejection fraction (LVEF) were not significantly changed after surgery in group II, except for the parameters AA1, AA2 and a2 (P>0.05). Conclusions Most of the mitral valve parameters were much better in group I after surgery. However, the malformation of papillary appa-ratus, leaflet tethering strength and left ventricular function were unchanged in group II, which may be the key mechanism of mitral regurgitation after surgery.

Maternity insurance is a policy support of China for women of child-bearing age.Given its good outcomes since it is enforced clinically,such insurance has been confronted with challenges as well.Doctors and nurses of Ob/Gyn departments serve as both protectors of parturient women's interests and practioners of the economic and social interests of the hospital.This paper summarized the experiences of maternity insurance of the Ob/Gyn department of the hiospital in rencent 6 years.The hospital has had 2026 inpationts covered by maternity insurance,without any medical disputes and harvesting a cash surplus of 657145 yuan.Such doctors and nurses are found to play a key role in ensuring a good doctor-patient relationship,and serve as clinival references for the single-disease management and teaching of the hospital.

ObjectiveTo investigate the effects of sex hormones( 17 β-estradiol and testosterone)on human omental preadipocytes proliferation and differentiation and on leptin and adiponectin secretions in adipocytes.Methods Omental preadipocytes were cultured and then differentiated into mature adipocytes in vitro.The proliferation and differentiation processes of preadipocyte were observed.The preadipocytes were incubated in the presence of sex hormones and were detected the contents and gene expressions of leptin and adiponectin.ResultsHuman preadipocytes were primarily cultured successfully.Estradiol stimulated preadipocytes proliferation (0.823±0.059 vs 0.276 ±0.032,P＜0.05 ),and inhibited lipid accumulation in cell differentiation ( P＜0.05 ).Testosterone had no significant effect on proliferation of preedipocytes,but inhibited adipogenic differentiation ( P＜0.05).Leptin could be detected during proliferation and differentiation of preadipocytes.Estradiol increased the leptin secretion,whereas testosterone reduced it ( all P ＜ 0.05 ).The adiponectin only could be detected during differentiation.Sex hormones reduced the adiponectin secretion.17β-estradiol stimulated leptin mRNA expression and suppressed adiponectin mRNA expression in adipocytes.Testosterone suppressed the mRNA expressions of leptin and adiponectin (all P ＜ 0.05 ).ConclusionIn vitro,17β-estradiol increases the leptin secretion and mRNA expression whereas reduced the adiponectin secretion and mRNA expression.Testosterone reduced the adiponectin and leptin secretion and mRNA expression.

Objective: To examine the microbial flora within the root canals with failed root canal therapy by PCR test, to identify detection rate of bacteria and the predominant bacteria species, and to determine the association of the various species with clinical features. Methods: Forty roots with failed root canal therapy were selected for this study. According to clinical features the roots were divided into three groups: pain, fistula and symptomless. After removal of the root filling material, the microbial samples were taken from the canal and detected by PCR test. Results: The microbial flora within root canals of teeth with failed root canal therapy was found to be mixed, six kinds of bacteria were detected. Enterococcus faecalis was the most commonly recovered bacteria species. Significant associations were observed between Prevotella nigrescens and pain, while dependablity was observed between Actinomyces israelii and fistula. Conclusion: The main cause of root canal treatment failure is the persistent microorganisms. The composition of bacteria in teeth with failed root canal therapy has its own specificity.

Diabetes is seriously hazards to human health and its pathogeneses are not clear. Recent studies show that the imbalance of intestinal flora and the development of diabetes are closely related. Appropriate bacteria can improve blood sugar disorder. Treating diabetes from the theory of Pi-Wei is effective. Regulating intestinal flora has become a new pathway for treating diabetes from the theory of Pi-Wei. On the basis of intestinal flora, authors discussed the treatment of diabetes from Pi and Wei.

AIM:To be one of the primary cause injury to multiple sites of ocular of glaucoma which affects over 70 million people worldwide. We applied data mining techniques, linear and the matrix operations, efficiently calculated the network and estimated the possible function of the“node” genes of the retina and optic of glaucoma, in order to provide new thought and method on the pathogenesis of glaucoma.
METHODS: The data in this study is from Gene Expression Omnibus ( GEO ) which belong to Nation Center for Biotechnology Information ( NCBI) , the quality of the raw data CEL files was processed and analyzed by the Expression software which belong to Affymetrix Inc. , Santa Clare, CA, USA. Significant analysis method ( SAM) which base on the T test was used to identified the significant genes. Based on GRNInfer and Gvedit soft we set up gene networks of optic and retina of mice and further more enriched analysis which based on DAVID and MAS3. 0 online software were processed.
RESULTS:The analysis between the group of the optic nerve heads and retinas in different stage of glaucoma showed that the amount of significant different expressed genes in the optic never head group increased significantly comparing with the group of retina in the early stage of glaucoma, the analysis of the genes network construction show that:the node genes of optic nerve heads included Unc13c、Kif5a、TRPM1、PANX; and the node genes of retina include POU4F1, NEFL, BC03870, CALB2. Metabolic pathways enrichment analysis which based on MAS3. 0 online platform show that there was mainly the amyotrophic lateral sclerosis, tyrosine metabolism, melanogenesis, Nitrogen metabolism, Gap junction, Leukocyte transendothelial migration metabolism pathway enriched out in optic nerve head; and there was mainly amyotrophic lateral sclerosis, neurodegenerative disorders, prostate cancer, leukocyte transendothelial migration metabolism pathway enriched out in retina.
CONCLUSION:By understanding bioinformatics result, it seems optic were more sensitive than the retina to high intraocular pressure, and weather high expression of TYrp1 gene can be as a sensitive diagnostic item require more evidence back up. Functional enrich analysis of node gene showed that cytoskeleton reconstructed, molecular motor and nutrients transport function improve in optic; and in retina, the most prominent finding in retina was enrichment function modules were focus on regeneration, repairing and differentiation of cells, which remind that we should reinforce research on reparation of retina of primary glaucoma. Metabolic pathways enrichment analysis show that inflammatory response plays prominent place in optic and retina of primary glaucoma, because of the optic narrow and crowed anatomic shape, nutrient metabolism and substances transfer enrichment modules play an important role in optics of primary glaucoma.
