Objective To investigate the incidence,etiology,diagnosis,treatment and outcome of uterus rupture.Methods From January 1999 to May 2013,clinical data of 67 cases with uterine rupture in Woman's Hospital,School of Medicine,Zhejiang University were studied retrospectively.Results A total of 67 cases of uterine rupture with 21 +2--39 +2 gestational weeks out of 128 599 deliveries were recorded giving an incidence of uterine rupture was 0.052 1 ％ (67/128 599).Cesarean scar rupture were found in 59 cases (88％,59/67) and noncesarean scar rupture were found in 8 cases (12％,8/67).The causes of uterine rupture include 60 cases of scar uterus (59 cesarean scar cases and 1 myomyectomy scar case),2 cases of assisted delivery operation trauma,2 cases of malformed uterus,3 cases of unknown causes (all with artificial abortion history).Non obstructive dystocia and improper oxytocin use were found to be related with uterine rupture.Fifty-two cases of cesarean scar spontaneous incomplete rupture were found and repaired during repeated cesarean delivery without maternal and fetal complications.The remaining 15 cases need emergency rescue operation for fetal distress or dead fetus,severe acute abdomen,prepartum or postpartum vaginal bleeding even maternal hypovolemia; 6/15 uterine rupture cases were diagnosed with the history,clinical symptoms and signs,3/15 cases with ultrasonic found dead fetus in the peritoneal cavity before exploratory laparotomy and 6 cases were diagnosed just during laparotomy.Hysterectomy was done in 10/15 cases and uterine repair in 5/15 cases; there was no maternal death and 12 perinatal fetal death (5 cases of mid-late pregnancy termination for deformed fetus) of the 15 uterine rupture cases.One case with hysterectomy was complicated with stress pancreatitis and dysfunction of liver and kidney and discharged 20 days after operation,the remaining 14 cases were discharged 5-7 days postpartum.One case with repaired malformed uterus got pregnancy 4 years later and delivered a 2 000 g healthy baby by cesarean section at gestational age of 33 +4 weeks.Conclusion Uterine scar caused by caesarean section or other operations became the leading cause of uterine rupture,assisted delivery operations,history of intrauterine manipulation and uterine malformations were the predisposing risk factors of uterine rupture.

AIM To investigate the changes of biochemical index of osteoporosis in rats induced by given total flavonoids of herba epimedii (HEF) . METHODS The rat osteoporosis was induced by given retinoic acid intragastrically, the biochemical index in serum (T, E 2, ALP, PTH, BGP, Osteocalcin ) and in urine (Ca, P, DPD and Cr) were determined after the rats were given HEF by low, middle and high dosages respectively, and were compared with the model group. The normal control and the positive control. RESULTS The E 2, T and BGP level in all three dosage groups were obviously higher than that of the model group. The Ca/Cr, DPD and PTH level were obviously lower than the model group. The content of Ca and P and the bone density in femur were similar with the normal control, and there was significant difference compared with the model group. CONCLUSION HEF prevents the rats treated by retinoic acid from becoming osteoporosis. The changes of biochemical index were consistent with the variation of bone density, indicating the great significance of biochemical index in diagnosis and treatment of osteoporosis.

Objecfive Most prostate cancer contains two or more widely separate turnors.To study the origin of prostate cancer based on the analysis of microsatellite alteration in separate tumors from the same prostate.Methods A polymerase chain reaction (PCR) was used to examine the allelic loss pattern of 4 microsatellite polymorphic markers on chromosome 8p (D8S133,D8S136,D8S137) and 17q (D17S855) in multifocal tumors of prostate from 19 patients.DNA samples were obtained from different regions of distinctly separate tumors on single case using microdissection technique.Results The overall frequence of LOH at D8S133,D8S136,D8S137 and D17S855 for all informative cases was 74%,38%,86% and 46%respectively in 40 separate tumors of prostate from 19 patients.The pattern of allelic loss was not identical in 15 of 18 (83%) informative cases. It showed that the different regions of prostate cancer were independent origin respectively.Discordant pattern of histology was observe in distantly separate regions.whereas the same allele was consistently lost in samples from different regions of the same tumor in 3 cases. Condusion Current data supports independent origin of multiple tumors in most prostate cancer patients.

Objective To observe the effect of Jinshui Liujun decoction on airway lesions in mice with COPD and explore its possible mechanism.Methods 48 C57BL/6 mice were randomly divided into blank group,model group,Jinshui Liujun decoction group and NAC group,with 12 in each group.The COPD mouse model was established by intranasal drip of LPS and smoking,and the corresponding drugs were given intragastric administration for 14 days after the model was established.Observe the general condition of the mice,measure the MV,PEF and PIF of the mice with the small animal lung function instrument,semi quantitatively evaluate the inflammation of the lung tissue,the thickness of the alveolar septum and the thickness of the airway wall with HE staining,and observe the airway mucus secretion and goblet cell proliferation with PAS staining.The content of MPO,SA and Urea in BALF was detected by the kit,and the ratio of SA and Urea was calculated.The content of MUC5AC in BALF was detected by ELISA.The levels of ROS,GSH,GSSG and GR in lung tissue were detected with the kit,and the ratio of GSH and GSSG was calculated.The expression level of CFTR mRNA in lung tissue was detected by qRT-PCR.Western blot was used to detect the expression level of CFTR protein in lung tissue.Results Compared with the control group,the growth of mice in the model group was poor.The body weight at each time point during the modeling period decreased(P<0.01),and the indexes of MV,PEF and PIF decreased(P<0.01).The lung tissue pathological score,alveolar septal thickness,airway wall thickness,airway mucus and goblet cell increased(P<0.01).The levels of SA,SA/Urea,MUC5AC and MPO in BALF increased(P<0.01),and the level of Urea decreased(P<0.01),The levels of ROS and GSSG in lung tissue increased(P<0.01),and the levels of GSH,GSH/GSSG,and GR decreased(P<0.01).The expression levels of CFTR mRNA and protein in lung tissue decreased(P<0.01).Compared with the model group,the growth condition of COPD mice improved,the body weight increased at each time point during the modeling period(P<0.05,P<0.01),the indexes of MV,PEF and PIF improved significantly(P<0.01),the pathological score of lung tissue,the thickness of alveolar septa,the thickness of airway wall,airway mucus and goblet cell decreased(P<0.01,P<0.05),and the levels of SA,SA/Urea,MUC5AC and MPO in BALF decreased(P<0.01),And an increase in Urea levels(P<0.01),a decrease in ROS and GSSG levels in lung tissue(P<0.01),and an increase in GSH,GSH/GSSG,and GR levels(P<0.01).The expression levels of CFTR mRNA and protein in lung tissue increased(P<0.01).Conclusion Jinshui Liujun decoction can correct CFTR acquired defects through antioxidant effects to improve airway lesions in COPD.
