Objective:To study the incidence,risk factors and clinical manifestaion for ectopic pregnancy(EP)after in vitro fertilization and embryo transfer(IVF-ET). Methods:A retrospective study of IVF and intracytoplasmic sperm injection (ICSI) pregnancies was performed between January 2002 and July 2005. Results:A total of 668 woman conceived after IVF or ICSI were studied. The rate of EP was 8.2%,corresponding with 55 Eps,of which 15 were heteropic pregnancy(HP). There were 40 Hps in tubal facter group,There apper to be no relationship between d2 ET and d 3 ET,ovulation induction and age. Conclusions:Tubal pathology is associated risk of EP.

The active form of vitamin D,1,25-Dihydroxyvitamin D3 \,is a secosteroid hormone that binds to the vitamin D receptor(VDR),a member of the superfamily of nuclear receptors for steroid hormones,thyroid hormone,and retinoic acid.1,25-Dihydroxyvitamin D3 and its analogue regulate calcium and bone metabolism,control cell proliferation and differentiation,and exert immunoregulatory activities.Recent advances in understanding their functions and novel insights into the immunomodulatory mechanisms they control suggest a wider applicability in the treatment of autoimmune diseases and induction of allograft tolerance.In addition to direct effects on T cell activation,1,25-Dihydroxyvitamin D3 and its analogue modulate with different mechanisms the phenotype and function of antigen-presenting cells(APC),and,in particular,of dendritic cells(DC).In vitro and in vivo experiments have shown that 1,25-Dihydroxyvitamin D3 and its analogue induce DC to acquire tolerogenic properties that favor the induction of regulatory rather than effector T cells.These intriguing actions of 1,25-Dihydroxyvitamin D3 and its nanlogue have been demonstrated in several experimental models and could be exploited,in principle,to treat a variety of human autoimmune diseases,or inhibit allograft rejection.

Strategy Management” is one of the best management models of the western countries. It can create outstanding achievements, obtain the long-term profit at the best degree, and cultivate an excellent management group. The feature of the model is to discuss the relationship between strategy and action. It is a new model coming from commercial management, which combines the strategy thought with the organization action. In order to guide the higher medical education evaluation of our county, we should learn from the strategy management thought and the operative method.

Objective To observe the change of Wnt-β-catenin signaling's location and expression in kidney repair after acute kidney injury induced by ischemla reperfusion (I/R).Methods Ischemia reperfusion injury in BAT-gal reportor mice was made and blood sample was taken from tails on the 1th day after injury. Mice were sacrified on the 2th or 7th day and kidneys and blood were collected. Renal pathological change was observed by PAS stain. The changes of location and expression of Wnt-β-catenin signaling were detected by immunofluorescence costainning X-gal-LTL, X-gal-NKCC2, X-gal-DBA respectively. The protein expressions of the Wnt4 and co-receptor Lrp6 were assessed by Western blotting. Results PAS-stained kidney sections showed desquamative or flattened epithelia, necrotic debris on day 2 and regenerating tubules on day 7. An injury-induced enhancement of the Wnt pathway response (X-gal staining) in kidney cortex and out-medulla. Immunolabelling of kidney sections from injured BAT-gal mice revealed that X-gal staining was detected in kidney epithelial cells (double-labelled with LTL or NKCC2). Western blotting showed the Wnt4 protein was up-regulated and phospho-Lrp6, indicative of active canonical Wnt signaling, was noted in kidney cortex from day 2 after I/R, but in control kidney cortex pLrp6 was not detected. Conclusion Wnt-β-catenin signaling is activited after acute kidney I/R injury and is required for tubular epithelial repair and regeneration following kidney I/R injury.

Based on the pathogenesis and symptom of rheumatoid arthritis (RA), professor LIN Guohua's unique opinion and method for RA in clinical treatment are summarized and analyzed. In the opinion of Professor Lin, RA is considered as "Jinbi" and "Gubi" in TCM, which is caused by deficient root with superficial excess. Based on the symptoms of RA, attention should be focused on lung-kidney diagnosis and treatment, and gold and catgut implantation at acupoint can be mutually combined, which is aimed to provide a special and effective method for clinical treatment of RA.

Objective: To study clinical significance of endogenous vitamin C 、 E in patients With hypertension and stroke. Methods: The serum vitamin C、 E, Malondialdehyde (MDA), superoxide dismutase (SOD) were determined by ultraviolet spectrophotometry in patients with hypertension (23 cases)、 hypertensive cerebral hemorrhage (CH, 30 cases)、 ischemic cerebrovascular disorders (IC, 25 cases) and control groups (20 cases). Results: Compared with control group, at acute stage of stroke, the Vit C、 E and SOD levels significantly reduced (P＜0. 01), the MDA level significantly increased (P＜0.01); at convalescent stage, the Vit C、 E gradually recover to normal, the SOD still reduced (P＜0.05), the MDA still incresed (P＜0.05). Conclusion: The endogenous Vit C、 E have significant change in patients with acute stage of stroke, it gradually recovers to normal in convalescent stage. Meanwhile the SOD and MDA change accordingly.

Pancreatic cancer has a strong ability of invasive and metastasis,and the mechanism is still not completely clear.It has been demonstrated that aberrant expression of microRNAs(miRNA) is closely associated with the occurrence,development and metastasis of pancreatic cancer.The reveal of miRNA mechanism related to the metastasis of pancreatic cancer would provide a new approach to the treatment of pancreatic cancer.

Chinese traditional surgery, an important branch of traditional Chinese medicine, has contributed greatly to the people's health in the history. With the fast development of modern medicine, Chinese traditional surgery is faced with serious challenges and its shortcomings have appeared more and more evident. In this article, the authors analyzed some problems in the development of Chinese traditional surgery and the opportunities for its further development, and suggested that the superiorities of Chinese traditional surgery should be enhanced in its future development.

Objective To investigate whether the effect of PBL is better than LBL when used in a new type of three phases labor trainee teaching. Methods 216 medical students of the five-year and seven-year program who took part in labor trainee in the 2013-2014 school year were chosen and divided into two groups:PBL group and LBL group. Both the two groups' labor trainee were performed as three phases: trainee preparation, delivery room trainee, and discussion-class after trainee. Ques-tionnaire investigations were used to evaluate the effect of the delivery room trainee and discussion-class in PBL group and LBL group. A quiz after the third phase was used to examine whether the teaching effect of the two groups is different or not. Statistical analysis was performed using SPSS 16.0 software. Count data between sample rates were compared by chi square test, mean data between the two groups were compared by t test, the inspection level is α=0.05. Results Both in the delivery room trainee and discussion-class after trainee, questionnaire score in PBL group was significantly higher than that in LBL group (P<0.05). The average of quiz score in PBL group was 25.7±2.1, which was significantly higher than that in LBL group (19.3±3.6) (P<0.05). The excellent rate in PBL group was 82.6%, which was also higher than that in LBL group (P<0.05). Conclusion PBL teaching method elevates learning initiative of medical students and increases the teaching effect, and it can be promoted in labor trainee teaching.
