Tumor 2010;(4):328-333
Objective:To evaluate the expressions of phosphorylated epidermal growth factor receptor (p-EGFR) and its downstream molecule phosphorylated AKT(p-AKT) in non-small cell lung cancer (NSCLC)and their significance. Methods:The immunhistochemistry was used to detect the expressions of p-AKT and p-EGFR proteins in 95 cases of NSCLC tissues. The relationship between the p-AKT and p-EGFR and between their expression and prognosis were also evaluated. Results:The positive rate of p-EGFR was 57.89% (55/95) and was related with age, gender and histological type (P=0.008,P=0.003,P=0.009). The positivity of p-EGFR was higher in young group (33/46), female group (24/30), and adenocarcinoma group (35/52). The positive rate of p-AKT was 66.32% (63/95) and was related with differentiation, lymph node metastasis and tumor size (P=0.036,P=0.047,P=0.017,res-pectively). The positivity of p-AKT was higher in low differentiation group (20/23), lymph node metastasis group (29/37), and tumor diameter ≤3 cm group (36/46). Univariate analysis showed that the expressions of p-AKT and p-EGFR were not associated with prognosis (P=0.854, P=0.729). Multivariate analysis showed that neither p-AKT nor p-EGFR was correlated with the patients' survival time (P=0.497, P=0.731). The p-AKT was positively correlated to the p-EGFR(r=0.204, P=0.047). Conclusion:The expressions of p-AKT and p-EGFR had no impact on the prognosis of NSCLC. They can not serve as prognostic indicators for NSCLC.

OBJECTIVE:To analyze the factors in the causation of cefradine-induced hematuria.METHODS:The material in CHINESE BIBLIOGRAPHIC DATA BASE OF BIOLOGY & MEDICINE(from 1980 to February 2001)and PHARMACEUTICAL ABSTRACTS(1990~2000)was reviewed and the data were analysed on patients'age and sex,route of drug administration,beginning of hematuria,prognosis and time of recovery.RESULTS:18 reports on cefradine-induced hematuria(108 cases) were found,which indicated that hematuria was mainly associated with renal hypoplasia in childhood and intravenous administration of cefradine.CONCLUSION:Intravenous administration of cefradine in children should be very careful.
3.Preventive effect of trimetazidine on contrast - induced nephropathy in patients with chronic renal insufficiency after coronary intervention
The Journal of Practical Medicine 2017;33(15):2558-2562
Objective This study was to investigate the role of trimetazidine in the prevention of contrast-induced nephropathy (CIN) in renal dysfunction patients undergoing coronary angiography. Methods A total of 151 patients with renal dysfunction who underwent coronary angiography were enrolled in our study and randomly divided into control group (n=77) and trimetazidine group (n=74). Standard hydration was administered in all the patients. In trimetazidine group, patients were administered trimetazidine orally for 48 hours before and 7 days after coronary angiography. Adverse events were observed in 12 months. Results (1) For 24 h and 48 h after the procedure:levels of SCr and CysC in the control group were significantly increased compared with baseline levels; levels of SCr and CysC in trimetazidine group were not increased, compared with baseline levels;levels of SCr and CysC were lower in trimetazidine group than the control group. (2)The incidence of CIN was reduced in trimetazidine group compared with control group (22.1%vs 9.5%,P=0.034). (3) Kaplan-Meier analysis showed that the incidence of adverse events in trimetazidine group was lower compared with the control group (P = 0.003). Conclusions Trimetazidine in combination with standard hydration is more effective than isotonic saline alone in protecting renal function in patients with renal dysfunction who undergo coronary angiography.

Chinese Journal of General Surgery 1993;0(02):-
Objective To establish standard liver volume formula of healthy Chinese and to explore if there is a correlation between changes of hepatic volume and hepatic functional reserve.Methods Two hundred and eighty healthy volunteers and 85 cirrhotics undergone serial abdominal H-CT scanning. The relation between normal liver volume measured by CT and body surface area(BSA) was studied by linear regression and correlation method, the standard liver volume formula was deduced. For cirrhotic patients, the change rate of liver volume was calculated and was compared with their Child class and postoperative complications.Results The mean normal hepatic volume for Chinese adults was (1?250?141)?cm 3. There is a positive correlation between estimated liver volume in vivo and body surface area[r=0.96, LV(cm 3)=613?BSA(cm 3)+162.8]. The mean liver volume (SD) for Child class A cirrhotics was (1?092?276)?cm 3, (868?163)?cm 3 for class B, and (652?76)?cm 3 for class C. Differences were observed among the three classes (P

Objective To evaluate the current situation and problems of the application of modified Rankin scale (mRS) in the outcome assessment in Chinese stroke trials. Methods Randomised and quasi-randomised controlled tri?als on stroke therapy published before September 2013 in 3 Chinese databases were included. All clinical trials applied mRS as the method of outcome assessment. Subarachnoid hemorrhage and transient cerebral ischemia were excluded. Types of stroke, statistical methods used for data analysis, duration of follow up, blinding of outcome assessment, types of intervention and the significance of the results were evaluated. Results Two hundred and ninety-eight trials were includ?ed in this analysis. 71.14%was for ischemic stroke, 21.48%for hemorrhagic stroke, 7.38%for both ischemic and hemor?rhagic stroke and 91.28%was for acute stroke(onset time<14d). Regarding to statistical methods used for data analysis, 50.00%of the trials used t-test or variance analysis which treated the mRS score as continuous data, while 22.15%used rank sum test or Chi-square test which regarded the mRS score as ranked data or multiply variable data. Dichotomous data was applied in statistical analysis accounts for 25.50%of trials. 12.42%trials applied mRS with other scales as the methods of outcome assessment. Duration of follow up ranged from 10d to 2 years (median 90 d, interquartile range 30-90 d). Only 5.03%assessed outcome blindly. 60.07%of the trials were drug therapy, 7.72%was rehabilitation thera?py, 10.40%were surgical treatment, 14.43%were combined therapy, 2.35%were management mode, 0.67%were nurs?ing, and 4.36%other therapy. Results in 86.91%of the trials were favorable to the tested interventions. Conclusions In aspects of, there is large difference between domestic and foreign clinical stroke trials in methodology of mRS including duration of follow up, blinding of outcome assessment and statistical methods used for data analysis.
