Objective To observe the repeat administration toxicity of Guanxinning Injection in rats.Methods Totally 120 rats (males and females) were randomly divided into vehicle control group and three Guanxinning Injection groups with different dosages (3.40,1.70,and 0.85 g/kg).Rats were administered with Guanxinning Injection by consecutive intravenous injection for 13 weeks.Besides the general conditions were observed,the related indexes were detected,such as body weight,the routine control of blood,hepatic function,renal function,the metabolism condition of lipids,the glycometabolism indexes,and histopathology analysis were determined at 13 weeks of treatments and 4 weeks after the withdrawal,respectively.Results Rats in the Guanxinning Injection group at 3.40,1.70 g/kg apperance shortness of breath,unsteady gait,lying motionless,and other symptoms.There was no obvious abnormal reaction in the 0.85 g/kg dose group.There were two male rats in the Guanxinning Injection group at 3.40 g/kg died at about week 4 of treatments,and there was no death in the 0.85 and 1.70 g/kg dose groups.Compared with vehicle control group,the related indexes of blood,blood biochemistry,organ relative quality,and histopathological showed no obvious abnormalities in Guanxinning Injection 0.85 and 1.70 g/kg group.The levels of urea nitrogen (BUN) and the relative weight of kidney in Guanxinning Injection 3.40 g/kg group were significantly higher than those in vehicle control group at 13 weeks.The change of these parameters regained to normal at 4 weeks after withdrawal and the rest of the detection index showed no obvious abnormality in 3.40 g/kg dase group.Conclusion Intravenous administration of Guanxinning Injection for 13 weeks at high dose could induce reversible damage to kidney.

Objective To observe the effects of propylene glycol mannate sulfate(PGMS) on the expression of ICAM-1 and VCAM-1 in kidney of diabetic rats, and explore the protective effect of PGMS on kidney. Methods Diabetes was induced by injecting STZ. Then the rats were randomly divided into four groups: normal control group, diabetic modal group, treatment group with high-dose and low-dose of PGMS. 8 weeks later, the blood glucose concentrations, HbA1c, the ratio of kidney weight to body weight, urinary albumin excretion rate (UAE ) in 24 hours were examined. The ICAM-1 and VCAM-1 located were detected by immunohistochemistry, while the expression of ICAM-1 and VCAM-1 were detected by Western blot method and the levels of ICAM-1 and VCAM-1 mRNA by RT-PCR.Results PGMS could reduce kidney hypertrophy and lower urinary albumin excretion rate (UAE)of 24-hour significantly. Immunohistochemical study with light microscopy demonstrated that the levels, both ICAM-1 and VCAM-1 in the kidney of test groups decreased obviously. PGMS down-regulated the mRNA and protein levels of ICAM-1 and VCAM-1 significantly . A positive correlation between expression of ICAM-1,VCAM-1 and kidney lesion was observed. Conclusion: PGMS decreased the expression of ICAM-1 and VCAM-1 in diabetic rats.

Objective:To investigatethe maternal and infant adverse outcomes of group B streptococcus (GBS) colonization during the late pregnancy.Methods:A total of 567 pregnant women who underwent obstetrics and gynecology examination in Yuyao People′s Hospital from December 2018 to June 2019 were selected for the study. Internal vaginal secretions of all the pregnant women were extracted from the lower 1/3 of the vagina for bacterial culture, and GBS culture and screening were performed on pregnant women. According to the results of GBS screening, pregnant women were divided into GBS negative group (8 cases) and GBS positive group (559 cases). The general condition and pregnancy outcomes of pregnant women were compared between the two groups, and the correlation between pregnancy outcomes and streptococcus colonization was analyzed.Results:There were no statistically significant differences in age, gestational weeks, number of births, number of pregnancies, history of abortion, residence area and ethnicity between the two groups ( P>0.05). The incidence of premature rupture of membranes and fetal distress in GBS positive group were higher than those in GBS negative group:5/8 vs. 7.69%(43/559), 3/8 vs. 5.01%(28/559), and the differences were statistically significant ( P<0.05). Spearman single factor correlation analysis showed that GBS colonization in pregnant women were positively correlated with premature rupture of membranes and fetal distress ( r = 0.632, 0.573, P<0.05). Conclusions:GBS colonization in late pregnancy is closely related to pregnancy outcomes, and strengthening GBS screening has great significance to reduce adverse pregnancy outcomes.

Objective To discuss the safety and efficacy of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture.Methods There was an retrospective analysis on operation videos and clinical data for 16 participants of inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture with the period from March in 2012 to September in 2015. And these were statistically analyzed including the operation time, intraoperative bleeding volume, postoperative drainage volume, removal time of drainage tube, admission time after operation and the incidence of postoperative complications of vesicoureteric reflux and stenosis.Results The operations of 16 participants were completed successfully without converting to open surgery. The operation time was 60 ~ 125 min (Mean time: 85 min); intraoperative bleeding volume was 20 ~ 50 ml (Mean volume: 32 ml); postoperative drainage volume was 60 ~ 400 ml (Mean volume: 106 ml); removal time of drainage tube was 3 ~ 6 d (Mean time: 4.2 d) and admission time after operation was 7 ~ 10 d (Mean time: 8.5 d). There was the follow-up with 6 ~ 18 months (Mean time: 12 months) for participants. No anastomotic stenosis was present. In addition, one participant was suffered from mild vesicoureteric relfux. And there was no aggravation during 18 months.Conclusions The inserting ureterovesical reimplantation by means of laparoscopy associated with six-stitch suture was safe and effective. It was found that the operation time was significantly shortened and the incidence of postoperative complications of vesicoureteric relfux and anastomotic stenosis was not increased. By contrast, the six-stitch suture could reduce the incidence of anastomotic stenosis.

Objective To evaluate the efficacy and safety of Houpu Paiqi mixture in treatment of functional dyspepsia (FD)with abdominal distension symptom.Methods From July 2014 to June 2015 , in nine centers,a total of 162 FD patients with abdominal distension symptom and met Rome Ⅲpostprandial distress syndrome (PDS)diagnostic criteria were enrolled.All patients were randomly divided into trial group and control group,81 patients in either group.The patients of trial group and control group took Houpu Paiqi mixture or placebo,respectively,25 mL per time,twice daily,and both the courses of treatment were two weeks.Before and after the treatment,the improvement of main symptoms,total clinical efficacy rate and efficacy of traditional medicine between two groups were compared.Chi square test,Fisher exact probability method and Wilcoxon test were performed for statistical analysis.Results According to the results of per-protocol (PP)analysis,the total efficacy rate of trial group and control group was 69.4% (50/72)and 59.2% (42/71),respectively,and there was no statistically significant difference in total efficacy rate between the two groups (χ2 =1 .650,P =0.199 ). And there was no statistically significant difference in the improvement of PDS main symptoms(postprandial fullnessand early satiety)between the two groups (56.3% ±27.9% vs 54.4% ±32.1%,t =0.606,P =0.727 ).For those with baseline symptom score over 14,median early satiety score of trial group after the treatment was 0,which was lower than that of control group,and the difference was statistically significant (Z =-2.370,P =0.018).The total efficacy rate of traditional medicine of trial group was 80.8% (59/73 )and that of control group was 72.0% (54/75 ),and the difference was not statistically significant (χ2 = 0.676,P =0.411 ).Conclusion Houpu Paiqi mixture has certain efficacy in FD with abdominal distension,and could be used for the treatment of PDS-predominant FD.

To investigate the relationship between the expression of RASSF1A protein and promoter hypermethylation of RASSF1A gene, RASSF1A protein expression was measured by Western blotting in 10 specimens of normal bladder tissues and 23 specimens of bladder transitional cell carcinoma (BTCC). The promoter methylation in BTCC and normal bladder tissues was detected by methylation-specific PCR (MSP). The results showed that the expression level of RASSF1A protein was significantly lower in BTCC tissues than that in normal bladder tissues. However, it was not correlated with its clinical stages and pathological grades. The frequency of promoter methylation of RASSF1A gene was higher in BTCC tissues than that in normal bladder tissues. In 14 patients with the aberrant promoter methylation, 13 showed loss or low expression of RASSF1A protein. It is concluded that RASSF1A gene promoter methylation may contribute to the low level or loss of RASSF1A protein expression, the inactivation of RASSF1A gene and the genesis of BTCC. But, it may bear no correlation with its clinical stages and pathological grades.
