12 cases of human placentas were obtained after administration of Chinese medicinal herb (Chuan-Xin-Lian) -induced abortion during mid-pregnancy. Six placentas from curettage induced abortion during mid-pregnancy were used as controls. All the specimens were studied histochemically and immunohistochemically by using antiserum to HCG with PAP method. In most of the specimens from women treated during mid-pregnancy, we observed a decreased immunoreaction of antiserum to HCG and a decrease of RNA content in the syncytiotrophoblasts. Increased activity of acid phosphatase in dccidual cells was observed during mid-pregnancy. These findings indicate that during mid-pregnancy, Chinese medicinal herb (Chuan-Xin-Lian) can reduce the synthesis of HCG in syncytiotrophoblasts and can initiate uterine contractions, so that abortion results. The possibility that the changes of lysosomal enzymes are involved in the initiation of uterine contractions is disscused.

[Objective]To approach the methods of difficult laparoscopic cholecystectomy.[Methods ]The clinical data of 116 patients with Mirizzi syndrome,severe adherence of abdominal cavity and Calot'triangle,liver cirrhosis underwent difficult laparoscopic cholecystectomy since 2004 were retrospectively analyzed.[Results]Except 3 patients treated by abdominal operation,other patients were treated by laparoscopic cholecystectomy successfully.[Conclusion]The rates of open operation midway and complications are not increased in difficult laparoscopic cholecystectomy as long as dealing with them properly.

Objective To establish a model of DRG-like grouping of cesarean section patients in the Beijing area so as to observe its feasibility of controlling rising medical costs.Methods DRG-like grouping of cesarean section patients was conducted by case-mix/DRG.The patients were divided into 3 groups according to complications: the serious complication group,the moderate complication group,and the minor or no complication group.Results The rate of cesarean sections remained at 50% or so in Beijing.A statistical analysis showed a significant difference between the 3 groups in costs and length of hospital stay.70% of the cases in the serious complication group belonged to the high cost group whereas 70 % of the cases in the minor or no complication group belonged to the low cost group.Conclusion The main ways of controlling rising costs for cesarean sections include reducing the rate of cesarean sections and(adopting) DRG-like PPS payments in view of the nature of medical insurance and government payments for cesarean sections.

Objective To investigate the diagnostic value of serum high density lipoprotein cholesterol (HDL-C), serum albumin (SA) and C reactive protein ( CRP) levels combined detection of severe acute pancreatitis.Methods 180 cases of acute pancreatitis were selected from January 2012 to January 2015 in Tianjin fifth central hospital,including 87 severe acute pancreatitis ( SAP) and 93 mild acute pancreatitis ( MAP) , and 100 cases of healthy people were selected as control group.The serum levels of HDL-C, SA and CRP were compared among three groups.Results HDL-C and SA in SAP group and MAP group were significantly lower than control group (P<0.05), the level of CRP was significantly higher than that of control group ( P<0.05); HDL-C, SA levels in SAP group were significantly lower than those of MAP group, the CRP level was significantly higher than that of MAP group (P<0.05).Compared to HDL-C and SA, the sensitivity(89.4%), specificity (95%) and accuracy (92%) of CRP were significantly higher (P<0.05).The sensitivity(93.6%)and specificity (95%) and accuracy (94.3%) of combined detection of three markers were significantly higher than the detection results of the three indexes either,the differences were statistically significant (P <0.05).Conclusion The combined detection of serum HDL-C, SA and CRP levels can effectively improve the early diagnosis rate of SAP, and provide reference for clinical diagnosis.

Stem cells offer considerable promise in the repair or replacement of damaged tissue in the body.Mature and functional endothelial cells play a pivotal role in neovascularization and maintenance of blood vessel integrity.Although being the best choice for transplantation endothelial,cells isolated from autologous vessels have been heavily obstacled in medical application due to poor resources and limitted proliferation potential in culture.Thus,stem cells have been the focus of the studies soareh for suitable cell sources.Several types of stem cells have been reported to possess endothelial cell differentiation potential.This article summarized the recent study on the sources,distribution,features-differentiation,animal experiments and clinical use of stem cells.Advantages and disadvantages are compared to provide a reference for the choice of evdothelial celia source.
