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.

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.

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.

Familial hypercholesterolemia(FH) is a common autosomal dominant dyslipidemia,which is caused by mutations of the low-density lipoprotein receptor(LDLR) gene producing defect or deficiency in LDLR.The characters of FH are elevated level of total and LDL cholesterol.FH is considered to be a complex polygenic disease.Recently,more findings indicate that proprotein convertase subtilisin/kexin type 9(PCSK9) gene play an important role in serum cholesterol metabolism.Some mutated PCSK9 proteins decrease LDLR,which cause FH in affected families.Some other mutated PCSK9 proteins decrease self-affinity,which cause hypocholesterolemia.We review the newest researches about the structure,function ofPCSK9 gene and the relation of its mutations with plasma cholesterol metabolism.

Intracoronary effects of calcitonin gene related peptide (CGRP) on coro-nary hemodynamics were observed in the normal and following different extent of coro-nary stenosis using graded coropary- stenosis modl in dogs. The results showed that CGRPincreased the coronary artery blood flow (CBF) and distant coronary blood prepsure (DCP),but decreased mean artery pressure (MAP), coronary vessels total resistance (R_T),large co-ronary vessels, resistance (R_L) and small coronary vessels resistance (R_s). Thirty minutesafter. coronary middle. stenosis, CGRP was given intracoronary, MAP had no significantchange, but CBF insreased and R_T R_L, R_s decreased, and which maintained for 30 min. 30min after coronary severe stenosis, CGRP increased CBF and MAP, but decreased DCP,R_T, R_L, R_S continuously. These results suggested that CGRP could ameliorate myocardialischemia through enlargement of coronary vessels and by increasing CBF.

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.

[Objective] To observe the effect of acupoint massage and TCM featured nursing on peripheral facial paralysis. [Method] Randomly divide 90 cases into 2 groups, n=45 for each group; the control group takes general treatment and acupuncture, the observation group is added with facial acupoint massage coordinated with mental counseling, recovery training and other TCM featured nursing, 1 time/d. [Result] After 2~4w of treatment, observe their clinical effects, the results had marked difference. [Conclusion] The cure effect of the observation group was better than common acupuncture group, showing that facial acupoint massage coordinated with TCM featured nursing treating peripheral facial paralysis could promote patients ’early recovery, much reduce the sequelae.
