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 study the diagnosis and treatment of aldosterone producing adenoma of the adrenal gland. Methods From January 1988 to January 2000,69 cases of aldosterone producing adenoma of the adrenal gland were diagnosed and treated.The diagnosis was all confirmed on open surgery and pathological studies. Results In all the patients,serum potassium level resumed to normal range in a week postoperatively.48 patients have been followed up for 3 months to 10 years,in 45 of them the blood pressure dropped to normal.In the other 3, drugs are still needed to control blood pressure after operation. Conclusions Spironolactonum test and serum aldosterone assay were the main methods of qualitative diagnosis of aldosterone producing adenoma.The location of the growth was mainly assessed on B ultrasono graphy and CT, the diagnostic accuracy being 81.2 percent and 100 percent respectively.Operation was the effective treatment method for aldosterone producing adenoma.

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

Objective To evaluate the effect of percutaneous coronary intervention(PCI) on myocardial perfusion in coronary heart.Methods Fourty-two patients with coronary heart disease who were confirmed to have coronary artery steonsis by the coronary angiography were selected.They were checked by myocardial contrast echocardiography of intravenous before and after treatment by PCI.Then we determined quantitatively the perfusion of coronary microcirculation based on the extent of myocardial imaging and recorded it images.The myocardial contrast echocardiography result was compared before and after treatment by PCI for evaluating the situation of myocardial perfusion and effect of PCL So we can estimte the patients' prognosis.Results There were 39 eases of 42 patients with PCI that their lesion vascular were all opening and unblocked.Repeated radiography showed that their TIMI blood flow was the third level.The partial cross sectional area of all the capillaries [A =15.46 ± 3.27) min] blood flow velocity [β =(0.75 ±0.16)min/s],and myocardial blood flow volume[A - β =(12.00 ±4.51 ) min2/s] dependent on myocardial segments all increased more significantly than those before the PCI[A =(6.68 ± 1.76) min,β =(0.40 ± 0.12) min/s、A · β =(2.82 ± 1.38 ) min2/s] (t =37.2527.58、30.65,P ＜ 0.05 ).After PCI three months the EF value of follow-up patients was increased mote than that of before PCI (t =13.77,P ＜ 0.01 )but the scoring index of ventricular wall motion was decreased more than that of before PCI ( t =8.75,P ＜ 0.01 ).Correlation analysis showed that after PCI A,β,A · β all had a strong correlation ( every P ＜ 0.01 ).Conclusion PCI could effectively improve the situation of myocardial perfusion in myocardial infarction patients.It could save ischemia myocardial in infarction field and also improve the function of left ventricular if patients implemented PCI operation as soon as possible.

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.

Objective　To study the changes of quantitative expression,adhering activity and genomic density polymorphism of complement type 1 in erythrocytes (CR1) of patients with liver cancer (104 patients) and their clinical significance.Methods　Polymerase chain reaction (PCR),HindIII restriction enzyme digestion,the quantitative assay of ECR1 and the adhering activity assay of CR1 in erythrocytes were used.Results　No difference was observed between the patients with liver cancer (29.8%) and healthy individuals (25.3%) in the spot mutation rate of CR1 density gene (χ2 =0.537,P>0.05).The number and the adhering activity of CR1 in patients with liver cancer (0.83±0.22 and 47.1±6.5) were significantly lower than those in healthy individuals (1.26±0.33 and 62.4±7.6; t=10.5,P<0.0001).The number and the adhering activity of ECR1 in high expression genomic type (HH) liver cancer were obviously lower than those of healthy individuals,expecially those of the patients with advanced liver cancer.There was a good relationship between quantitative expression,adhering activity of ECR1 and liver cancer development.Conclusion　Defective expression of CR1 in liver cancer is mostly acquired through central peripheral mechanisms.The changes of CR1 quantitative expression and adhering activity are consanguineously related to the severity and the activity of the development in patients with liver cancer.
