Hydronephrosis is one of the most common urological diseases in children.Most of hydronephrosis caused by ureteropelvic junction obstruction.Whether these children need operations were being argued.The current tendency is when the renal function become worse,operation is suggested needed,in order to save the renal function.So the methods how to evaluate the renal function are especially important,this article related to the current research and review.

Objective To evaluate the changes in esophageal pressure and 24h pH on the pathogenesis of esophagitis by means of a multivariate logistic regression analysis of obtained values. Methods Monovariate comparison of parameters from 24h ambulatory esophageal pH measurements and esophageal manometry between two groups of gastro-esophageal reflux disease (GERD) patients, including 45 with esophagitis, 40 without esophagitis, and 42 healthy controls. Multivariate logistic regression analysis of parameters obtained was carried out. Results All parameters of DeMeester-Johson score were significantly higher in esophagitis than those of without esophagitis. The composite scores were 113.29?26.73 and 42.66?11.25, respectively (P

0.05) . Conclusion Air pollution can increase the risk of low birth weight and preterm birth in the exposed pregnant women.

Objective To explore the effects of exogenous glutathione on arsenic distribution and nitric oxide (NO) metabolism in the brain of mice exposed to arsenite through drinking water. Methods Female Kunming mice were randomly divided into 5 groups, eight in each, and the mice were exposed to sodium arsenite through drinking water at doses of 0 mg/L (control) and 50 mg/L arsenic for 4 consecutive weeks, on the fourth week, with the exposure of arsenic, glutathione was given through intraperitoneal injection at doses of 200 mg/kg b.w, 400 mg/kg b.w or 800 mg/kg b.w, respectively for 7 days. In the end of treatment, the samples of blood and brain were collected. Levels of inorganic arsenic (iAs), monomethylarsonic acid (MMA) and dimethylarsenic acid (DMA) were determined by HG-AAS method. Activities of nitric oxide synthase (NOS) and the concentrations of NO were determined with kits. Results Compared with those in single arsenic group, glutathione significantly decreased levels of iAs, MMA and total arsenic levels (TAs) in the blood and levels of DMA and TAs in the brain. Activities of NOS and levels of NO in As group were significantly lower than those in control, however administration of glutathione could ameliorate these toxic effects, and NOS activities in groups treated with 400 mg/kg b.w and 800 mg/kg b.w glutathione were significantly higher than those in single arsenic group. Conclusion Exogenous glutathione may promote methylation of arsenic, therefore reduce arsenic levels in both blood and brain. Moreover, it is proposed that administration of exogenous glutathione can ameliorate the adverse effects of arsenic on NO metabolism in the brain via decreasing the brain arsenic burden.

Objective To investigate the clinical therapeutic effects of neuromuscular electric stimulation (NMES) on patients with swallowing disorders after stroke. MethodsA total of 98 patients with a swallowing disorder after stroke were randomly divided into an NMES group (38 cases),a rehabilitation group (30 cases) and a control group (30 cases).In the control group the patients were treated with medication only; the in rehabilitation group they were treated with medication and swallowing rehabilitation training; in the NMES group they were treated with medication and NMES.The treatments lasted for 3 weeks in all groups.The swallowing function of patients in each group were observed and assessed with dysphagia scoring pre-and post-treatment.Complications of the swallowing disorders,side effects of treatment and the stomach tube leaving rate were observed. ResultsAfter treatment,the dysphagia scores of patients in the NMES and rehabilitation groups both increased,but the average scores in the NMES group were significantly higher than in the rehabilitation and control groups.The difference in therapeutic effect between the three groups was statistically significant.After treatment,the incidence of aspiration pneumonia in the NMES group was significantly lower than that in the control and rehabilitation groups.The average stomach tube leaving rate in the NMES group was significantly lower than that in the control group,but there was no significant difference in stomach tube leaving rates between the rehabilitation group and the NMES group.There was no significant difference among the three groups in malnutrition.No side effect was observed in any group.Conclusions NMES could alleviate post-stroke dysphagia and decrease the incidence of aspiration.The short-term therapeutic effect of NMES was better than that of swallowing rehabilitation training,but the long-term therapeutic effects were about the same in the two groups.
