Objective To establish the quality standard of Xiaoer Runtu granule.Methods Xiangfu,Baizhu,Sharen and Chenpi were identified by TLC.The content of paeoniflorin was determined by HPLC.Results TLC could identify Xiangfu,Baizhu,Sharen and Chenpi.The peoniflorin showed good linear correlation at the range of 1.176～11.760 ?g,r=0.999 99,the average recovery of paeoniflorin was 99.42%,RSD=2.26%.Conclusion The method is simple and can be used to control the quality of Xiaoer Runtu granule with high accuracy and good reproducibility.

0.05). Conclusion The sinus node arteries can generally be found by angiography. There is no significant relationship between coronary artery diseases of sinus node and sick sinus syndrome.

Objective To investigate the changes of umbilical adiponectin(APN) levels in newborn whose mothers with gestational impaired glucose tolerance (GIGT).Methods Eighteen neonates of GIGT pregnancies and 50 controls of normal glucose tolerance (NGT) pregnancies were studied.APN concentration was qualified in the umbilical vein serum with radioimmunoassay methods.Capillary blood glucose was measured at the first hour after delivery.Results Umbilical APN level in the GIGT group was significantly higher than that in NGT group [(61.06?16.85)mg/L vs(48.04?15.47)mg/L,t=2.38 P0.05).Conclusions Umbilical serum APN levels are elevated in newborns of GIGT mo-thers.This may be due to the dysregulation of serum APN levels associate with GIGT pregnancy.More attention shall be paid to the metabolic changes of GIGT mothers and their offspring.

Objective To study the clinical effect and value of the combination of dexamethasone and calcium agent assisted oxytocin on preventing postpartum hemorrhage.Methods 128 cases of maternal of clinical information were reviewed,and which were divided into control group and observation group randomly.The control group was immediately infused muscle note 20IU of Oxytocin and the observation group(n =64) was given 5％ of glucose and 100ml 10％ of glucose acid 10ml calcium.And then give 20IU oxytocin after pending.Lastly,give the two groups comparison of blood-producing capacity and the number of cases of blood-producing.Results Ater observation groups in fetal foetus blood-producing capacity of 2h and 24h,the number of cases of blood-producing less than the control group,and both have significant statistical differences (all P ＜ 0.01).Conclusion The combination of dexamethasone and calcium agent-assisted application of oxytocin can prevent postpartum hemorrhage,better clinical effect,which should be promot in clinical application.

Objective To explore the safety and effectiveness of dexamethasone and calcium gluconate combined with oxytocin to prevent postpartum hemorrhage.Methods 128 maternal patients with full-term delivery were divided the patients into two parts randomly:the control group and the observation group,of which contained three groups(A,B,C).The patients were all given 20 u oxytocin.As to observation,group A:before 10-15min of cutting skin,give 10mg of dexamethasone and 10 ml 10％ calcium gluconate rapid intravenous infusion,group B:give 10mg intravenous infusion of dexamethasone after babies were boro,group C:before 10 ～ 15min of cutting skin,give 10mg of dexamethasone and 10ml 10％ calcium gluconate rapid intravenous infusion and then give 10mg dexamethasone after babies were born.The control group wasn't given that medicine,and only give them 20 u oxytocin when babies were born.At last,give contrast of total amount of bleeding,ill reflecting of medicine and the other symptom after 24h.Results The amount of bleeding of observation group A,B,C were (277.3 ± 44.5) ml,(286.8 ± 52.7) ml,(301.8 ±60.9) ml,respectively.The amount of bleeding of the control group was (422.9 ± 78.2) ml.The observation group and control group had significant differences(t =-0.699,0.481,-0.407,all P ＜ 0.01),and there was no significant difference between group A,B,and C (P ＞ 0.05).And this two groups had no bad reflection and the other symptoms.Conclusion Dexamethasone and calcium gluconate combined with oxytocin to prevent postpartum hemorrhage has great efficacy and safety.This method must be extended.

BACKGROUND:Along with the increasing improvement of bladder tissue engineering research, the vascularization of tissue-engineered bladder after implantation becomes an issue of concern. OBJECTIVE: Combined with relevant literature in recent years, to review the choice, design and application of scaffold materials for bladder tissue engineering as wel as vascularized strategies folowing implantation. METHODS:The first author retrieved PubMed database and CNKI databases for articles relevant to biological scaffold materials in bladder tissue engineering and vascularization of tissue-engineered bladder published between January 2000 to September 2014 using the keywords of “tissue engineering; bladder; biomaterials/scaffolds; vascularization” in English and Chinese, respectively. RESULTS AND CONCLUSION: Recently, the biological scaffolds for bladder tissue engineering include two main categories: natural biomaterials and synthetic polymers. The major target of bladder tissue engineering remains to prepare the best cel-seeded scaffolds, to determine the best source of stem cels, to explore the best differentiation way of stem cels, and to promote angiogenesis and nerve regeneration of implanted scaffolds. Thereinto, promoting vascularization of scaffold materials and building complex tissues is most chalenging. At present, it is stil difficult to precisely control the directional proliferation, migration and differentiation of the attached endometrial cels. Although the vascular network is necessary for the nutrient supply and metabolic waste removal of cels or tissues, strategies to promote angiogenesis or vasculogenesis are stil limited.

Objective To evaluate the association between cytomegalovirus (HCMV) infection and atherosclerosis (AS) and explore the possible role of endothelin (ET) and serum tumor necrosis factor(TNF ?) in the pathogenesis of AS in diabetic patients and the relationship between HCMV infection and concentrations of ET and TNF ?. Methods Blood samples were collected from 21 patients with AS of type 2 DM, 47 patients with non AS of type 2 DM and 20 controls. Special antibodies to HCMV (IgM,IgG) were measured by enzyme linked immunosorbent assay (ELISA) . The concentrations of serum TNF ? and plasma ET were determined by RIA. Results (1) Type 2 diabetic patients, especially those with established AS, had a higher prevalence of active infection of HCMV. (2) The levels of plasma ET and serum TNF ? in type 2 diabetic patients were higher than those in normal people. In the pathogenesis of AS in diabetic patients, the ET played more important role than the TNF ?.(3) There was a significantly positive correlation between anti IgM to HCMV and the level of plasma ET in type 2 DM patients. It suggested that the injury of endothelium cell was related to the active infection of HCMV. Conclusion The study suggests that HCMV infection may be important in the pathogenesis of AS in type 2 diabetic patients and ET possibly plays an important role on the pathological course of AS.

Objective To study the risk factors which lead to increase in the incidence rate of hypospadias. Methods A case-control design was used.The mothers of 210 cases and 420 controls were interviewed by telephone or face-to-face,and the questionnaires were answered.Thirty probable risk factors were investigated.Statistical analysis was performed using univariate and multivariate unconditional Logistic regression analyses for evaluation of the data. Results All boys with hypospadias in the case group were of Han nationality.Only 5 cases had positive family history.Odds ratio (OR) of the factors investigated were:pregnant age (OR,38.63),threatened abortion (OR,4.71),progestin (OR,3.64),estrogen (OR,5.1),pesticide (OR,2.39),organic solvents (OR,2.12),season of pregnancy (OR,1.86) and detergent (OR, 1.87).But OR of frequency of abortion,weeks of gestation and birth weight were less than 1.The results of other 17 investigated factors were negative. Conclusions Threatened abortion,nonfull-term fetus,low birth weight and some environmental endocrine-disturbing chemicals ( pesticide,detergent,organic solvents,progestin and estrogen) may be risk factors associated with hypospadias.These environmental endocrine-disturbing chemicals may increase the incidence rate of hypospadias.
