Chinese Journal of Obstetrics and Gynecology 2001;0(01):-
Objective To analyze the effects of routine early amniotomy on labor and health status of foetus and neonate. Methods The results of “Early amniotomy increases the frequency of fetal heart rate abnormalities, A randomized controlled trial of early amniotomy, Effect of early amniotomy on the risk of dystocia in nulliparous women, The influence of elective amniotomy on fetal heart rate patterns and the course of labor in term patients: A randomized study, Randomised trial comparing a policy of early with selective amniotomy in uncomplicated labour at term and A randomized controlled trial and meta-analysis of active management of labour were analyzed using Mantel-Haenszel method (fixed effect model) in meta-analysis. Results (1) The routine early amniotomy can shorten 94.90 min of the first stage of labor, 95% CI (-119.17,-70.52). (2) The OR for cesarean section was 1.25,95%CI (0.99-1.57),for instrumental vaginal delivery was 1.05, 95% CI (0.90-1.24). (3) There was no difference in abnormal fetal heart rate at first stage (OR=0.95, 95% CI: 0.75-1.21), but there was increased abnormal fetal heart rate at second stage(OR=1.28, 95% CI: 1.02-1.61). (4) The frequency of stained amniotic fluid and abnormal Apgar scores at 1 minute was not different significantly [ OR=1.17,95% CI (0.78-1.73);OR=0.71,95%CI: (0.49-1.03)]. Conclusions Routine early amniotomy appears to be associated with both benefits and risks. Beneficial effects include reductions in labor duration and possible decrease in frequency of abnormal Apgar score at one minute. Risks include increase in abnormal fetal heart rate at second stage and possible rise in cesarean section rate.

Objective To investigate the underlying mutation in a late-onset Chinese patient with classic Bartter syndrome. Methods The mutation analysis of CLCNKB gene was performed by the PCR direct sequencing. The patient's parents and siblings were studied as well. Fifty normal volunteers were analyzed as control group. Results The heterozygous deletion mutation cDNA 753delG and heterozygous missense mutation G433E were detected in the patient. Her father was found to carry heterozygous G433E and her mother to carry cDNA 753delG mutation respectively. Her brother carried heterozygous G433E and her sister was normal. Conclusions Two mutations of the CLCNKB gene in this Chinese patient with late-onset classic Bartter syndrome are identified. The cDNA 753delG mutation has not been reported previously.

Objective To investigate the clinical epidemiological characteristics of gastric carcinoma detected by endoscopy in Gansu province.Methods Data of patients with gastric carcinoma,which was detected by endoscopy and confirmed pathologically from January 1977 to December 2006 in 163 hospitals of Gansu province,were reviewed.The endoscopic findings,clinical manifestations and epidemiological features were retrospectively analyzed.Results A total of 34,116 patients were diagnosed as gastric carcinoma with the overall screening rate as 5.30%,which was decreasing in the recent years.The rate of cardiac and noncardiac cancer was 18.5%and 81.5%,respectively,and the rate of cardiac cancer raised from 16.1%to 20.0%in the last decade.The tumor was most likely detected in antrum(38.63%).The male/female ratio of gastric cancer is 3.56:1.The screening rate of gastric carcinoma was the highest in Wuwei district (8.19%).The poorly differentiated adenocarcinoma accounted for 49.64%in all patients.Conclusion Gastric carcinoma occurs most frequently in Wuwei district of Gansu province and was mostly detected in gastric antrum.The most common pathological type is poorly differentiated adenocarcinoma.In the past three decades,the detection rate of gastric cancer is decreasing,SO is that of cardiac cancer,and that of the early gastric cancer is relatively low.

Objective: To study the protective effect of glutamine on intestine in mice damaged by radiation. Methods: Mice were exposed to 137 Cs rays (dose of 4Gy) with the whole body. The protetive effects of glutamine on intestine radiational damages were studied. Result: After radiation, GSH contents, SOD activities, protein and DNA contents were decreased and MDA contents were increased in intestinal mucosa. Villus height was shortened, crypt depth was deepened, wall width and villus surface area were decreased. Glutamine supplement restrained the changes of indices above mentioned and made them close to normal levels. Conclusion: Glutamine supplement had the protective effect on radiation damage in mice.

Background and purpose:P38 mitogen-activated protein kinase (P38MAPK) signal transduction pathway is involved in occurrence, development and transfer process in a wide variety of tumors. Urokinase-type plasminogen activator (uPA) plays an important role in tumor invasion and metastasis. This study aimed to explore the clinical signiifcance of the P38MAPK signaling pathway and the expression of uPA in ovarian cancer.Methods:The expressions of uPA, P38MAPK, ERK and AKT were detected in 49 cases of cervical adenocarcinoma by immunohistochemistry. The expressions of uPA and P38MAPK were detected by Western blot in ovarian cancer cell lines HO8910, HO-8910PM, SKOV3 and CAOV3. The changes of uPA and P38MAPK were detected by SB203580, a speciifc inhibitor of P38MAPK signal transduction pathway.Results:The result of immunohistochemical method showed that positive expression rates for uPA, P38MAPK, ERK and AKT were 61.22%, 57.14%, 53.06% and 55.10%, respectively. The expression of the uPA was positively correlated with the P38MAPK (r=0.865,P=0.001), and related with clinicopathologic stage, differentiated degree, lymph node metastasis, but not related with age and histologic type (P>0.05). The expressions of AKT and ERK were related with the lymph node metastasis and greater omentum metastasis(P<0.05), but not related with age and histologic type (P>0.05). The expression of uPA in HO-8910PM was higher than that in ovarian cancer cell lines HO8910, SKOV3 and CAOV3, and the expression of uPA reduced when the P38MAPK signal transduction pathway was cut off by the SB203580. The expressions of P38MAPK and uPA were negatively correlated with the prognosis of ovarian cancer (Log-rank=3.897 and 11.044,P=0.048 and 0.001). Conclusion:The P38MAPK signal transduction pathway was activated in ovarian cancer. The activated P38MAPK signal transduction pathway can raise the expression of uPA, which may contribute to the development of ovarian cancer. The result indicates that the P38MAPK signal transduction pathway and uPA might play an important role in the invasion and metastasis of ovarian cancer. P38MAPK and uPA might be useful markers for evaluating prognosis of ovarian cancer.
