Objective To explore the oxidative stress pathogenesis of Parkinson's disease(PD) induced by paraquat in substantia nigra of mice. Methods The model of PD was established by oral administration of paraquat to mice.The spectrophotometry was used to determine the activities of superoxide dismutase(SOD) and glutathione peroxidase(GSH-PX) and the content of malondialdehyde(MDA) in substantia nigra.At the same time,number of tyrosine hydroxylase(TH) positive neurons in substantia nigra of mice was estimated by immunohistochemistry. Results The activities of SOD and GSH-PX were significantly decreased,and the content of MDA was increased in paraquat-treated mice compared to that of mice treated by saline taken orally(P

Objectives To analyze the clinical and pathological characteristics of gastric submucosal tumors (GSMTs), and evaluate the safety and efficacy of endoscopic treatment for GSMTs. Methods 61 patients with GSMTs were selected from June 2014 to September 2012 by endoscopy and ultrasonography;they were all treated by endoscopic therapy; pathological examination was took in all removed tumors, the tumors which could be the gastric stromal tumor were furtherly examined by molecular biology technique of immunohistochemistry. Result In 61 cas-es, 39 cases are female patients, accounting for 63.93%;the tumors located at the stomach fund accounted for 52.46%(32/61), at the gastric corpus for 21.31%(13/61), at the gastric antrum for 11.48 %(7/61), at cardia for 14.75%(9/61); 10 cases were treated by Endoscopic submucosal dissection, 21 by endoscopic submucosal excavation, 27 by Endoscopic full-thickness resection, 3 by Submucosal tunnelling endoscopic resection; in all 61 cases, 2 were changed to laparoscopic treatment because one tumor was too big and broke the Serous and another was located at mucus Lake of gastric fund, 1 occurred postoperative bleeding and was treated by laparoscopy successfully, 1 oc-curred postoperative perforation and was treated by endoscopy successfully; after pathological and immunohisto-chemical analysis, 34 tumors were identified as gastric stromal tumor and all of them in risk classification were at very low risk, 11 were leiomyoma, 5 were lipoma, 3 were heterotopic pancreas, 5 were calcifying fibrous pseudotu-mor, 2 were inflammatory fibroid polyps, and 1 was angiomatous proliferation; gastric stromal tumor at gastric fundus account for 73.53 % (25/34), at gastric corpus for 11.76 % (4/34), at gastric antrum for 5.88 % (2/34) and at cardia for 8.82 %(3/34). Conclusion Most GSMTs are found in female and commonly lack of specific clinical symptoms;GMSTs are commonly located at gastric fund and most of them are gastric stromal tumors, vast majority of gastric stromal tumors in the risk classification are at very low risk;the endoscopic resection is a mini-invasive, safe and ef-fective treatment for GSMTs.

Fluorescent staining method is a sensitive cytochemical staining method, it can reflect minimal changes of biochemical components of cells. The 7690-Xu fluorescent staining solution prepared with thioflavine can show the heterogeneo- us fluorescence of cells in different stages of differentiation. The younger cells with low degree of differentiation show blue fluorescence, the lower the degree the deeper the color. Along with the differentiation of cells, the blue color of fluorescence deflects to the red color of spectrum gradually, the blue color of fluorescence of cytoplasm changes gradually to bluish, bluish-green, and finally yellow color. The blue color of fluorescence of nucleus changes through greyish- blue to orangeyellow or orange-red.The cytoplasm of cells in various organs with high degree of differentiation appears yellow, and the nucleus orange-yellow or orange-red in color.

Objective To observe the level of serum hepatocyte growth factor (HGF) in patients with impaired glucose tolerance (IGT). Methods Thirty patients with IGT (IGT group), 30 patients with type 2 diabetes mellitns (T2DM) (T2DM group) and 30 healthy controls (control group) were recruited for this study. Such indexes as HGF, fasting plasma glucose (FBG), postprandial plasma glucose (2hPG), glycosylated hemoglobin A1c( GHbA1c ), fasting insulin(FINS), systolic blood pressure(SBP), diastolic blood pressure (DBP) were examined and these related factors were analyzed. Results The levels of serum HGF in IGT group and T2DM group were higher than those in control group [(413.22 ± 102.48), (422.76 ± 126.77 ), ( 120.45 ± 25.11 ) ng/L, respectively ] (P < 0.05 ). There was no significant different between IGT group and T2DM group (P> 0.05). There was positive correlation between HGF and FBG (r = 0.326, P< 0.05 ). Multiple regression analysis indicated significant correlation between HGF and DBP (r = 4.730, P< 0.05). Conclusion Higher levels of HGF are found in IGT patients, which indicates that function of vascular endothelium is abnormal in this period.

Objective To observe the level of serum hepatocyte growth factor(HGF)in patients with hypertension(HT).Methods HGF,fasting plasma glucose(FBG),postprandial plasma glucose(2hPG),glycosylated hemoglobin A1c(HbA1c),total cholesterol(TC),triglyceride(TG),systolic blood pressure(SBP),diastolic blood pressure(DBP),body mass index(BMI)and waistline(w)were detected in 30 patients with hypertension,30 patients with hypertension complicated by type 2 diabetes mellitus(T2DM),and 30 normal controls such indexes as.Results The level of serum HGF in HT group[(413.87±90.87)ng/L],and HT+T2DM group[(413.72±98.72)ng/L]were higher than that in control group[(120.45±25.11)ng/L](P＜0.05),but there was no significance between HT group and HT+T2DM group(P＞0.05).There existed a positive correlation between HGF and FBG,SBP(r=2.273,r=5.353,P＜0.05).Conclusion Higher levels of HGF is found in patients with hypertension and hypertensin complicated with T2DM,which indicates the severity of dysfunction of vascular endothelium.

Objective To evaluate the safety and efficacy of ultrasound-guided percutaneous microwave ablation of renal neoplasms.Methods Twenty-two patients with pathologically proven renal neoplasms(18 renal cell carcinoma,3 renal angiomyolipoma,1 oncocytoma)with diameters of 1.0 to 3.8 cm were treated by microwave ablation.Cooled-shaft needle antenna was percutaneously inserted into the tumors under ultrasound guidance.One antenna was used for tumors less than 2 cm,two antennas were used for tumors larger than 2 cm.One thermal couple was placed adjacent to the tumor monitoring temperature in real-time during ablation.Immediate treatment efficacy was assessed by contrast-enhanced ultrasound within 3 days after ablation.Short-term efficacy was assessed by contrast-enhanced CT and/or contrast-enhanced ultrasound at 1,3,6 months and every 6 months thereafter.Results Twenty tumors were completely ablated in a single session,2 tumors were completely ablated in 2 sessions.No complications occurred.No residual tumor or recurrence was observed during follow-up.Conclusions Ultrasound-guided pereutaneous microwave ablation appears to be a safe and effective technique for the management of renal neoplasms in selected patients.

Objective To investigate and analyze the adverse effect(AE) of methotrexate(MTX)in rheumatoid arthritis(RA).MethodsThree hundred and twenty-five RA patients were investigated with a questionnaire in clinical service of department of Rheumatology and Immunology, Peking University People's Hospital. SPSS 11.5 software was used for statistical analysis. Results① The total prevalence of AE was 34.2％. Among these, gastrointestinal AE were the most common, others included elevated liver enzymes,leucocytopenia,alopecia and dental ulcer. The incidence of drug withdrawal of MTX was 13.2％, elevated liver enzymes was the most common reason of withdrawal, other reasons were gastrointestinal AE, leucocytopenia,dental ulcer and alopecia. The gastrointestinal AE and dental ulcer occurred within one week after initiating the medication in average, while elevated liver enzymes and leucocytopenia usually occurred at about 1～2 months after the medication. ②The incidence of AE increased with the dosage. ③ Folic acid could significantly decrease the total incidence of AE(P＜0.05). The incidence of gastrointestinal AE, elevated liver enzymes,leucocytopenia and dental ulcer couldbe reduced by folic acid supplementation(P＜0.05).Conclusion The AE of MTX in RA treatment are common, many of which are slight and could be improved by reducing the dosage or symptomatic treatment. The AEs of MTX can be improved by folic acid supplement treatment.
