Objective:To evaluate the efficacy of remimazolam-propofol-sufentanil for anesthesia in patients undergoing painless gastroscopy.Methods:Eighty American Society of Anesthesiologists physical statusⅠor Ⅱ patients, aged 20-59 yr, weighing 44-69 kg, scheduled for elective painless gastroscopy, were divided into 2 groups ( n=40 each) using a random number table method: remimazolam-propofol-sufentanil group (group RPS) and propofol-sufentanil group (group PS). The patients in group RPS received successive intravenous injection of sufentanil 0.1 μg/kg, remimazolam 0.15 mg/kg and propofol (at a rate of 4 mg/s). The patients in group PS received intravenous injection of sufentanil 0.1 μg/kg and propofol (at a rate of 4 mg/s). When Observer′ s Assessment of Alertness/Sedation Scale score was 0, gastroscopy was performed.The consumption of propofol, time of anesthesia, time for gastroscopy, emergence time and discharge time were recorded.The number of intraoperative assisted respiration cases, body movement and occurrence of adverse reactions at the time of discharge were observed. Results:Compared with group PS, the consumption of propofol was significantly decreased, and the time of anesthesia, emergence time and discharge time were shortened in group RPS ( P<0.05). There was no significant difference in the time for gastroscopy, the number of intraoperative assisted respiration cases, body movement and the occurrence of adverse reactions at discharge time between the 2 groups ( P>0.05). Conclusion:Remimazolam-propofol-sufentanil produces better efficacy for anesthesia than propofol-sufentanil in patients undergoing painless gastroscopy.

Background and purpose: Astrocytoma is the most common neuroepithelial neoplasm, and its grading has profound effect on its treatment and prognosis. To investigate the application of stepwise discriminant analysis in grading astrocytomas, this study developed two models of stepwise discriminant analysis according to relevant factors of astrocytoma. Methods: From January 2008 to April 2009, 111 primary astrocytoma patients were enrolled. Each patient was scored based on location, signal intensity on T1WI, signal intensity on T2WI, enhancement, edema, border, cyst or solidness, and mass effect of their magnetic resonance images. With their age score of grading, Fisher stepwise discriminant analysis and the Logistic discdminant were used. The results from the two models were then evaluated and compared. Results: According to Fisher stepwise diseriminant analysis, the predictive accuracy was 87.7% with 80.0% sensitivity, 91.5% specificity and 0.942 area of ROC curve. However, the predictive accuracy of Logistic discriminant analysis was 84.9% with 80.0% sensitivity, 86.8% specificity and 0.940 area of ROC curve. There were no statistically significant differences in terms of accuracy (P=0.250) and areas under ROC curve (Z=0.433, P=0.665) between the two models. Conclusion: Two stepwise discriminant analysis models are meaningful to predict the grading of astrocytoms, and the application of Fisher stepwise discriminant analysis is simpler than the Logistic discriminant analysis.

Study the serum level of HGF, Cys C and TGF-beta1 in type 2 diabetic nephropathy (DN), the infect of Pingshen decoction on those index. Selected 69 cases of 2 type DN and randomly divided into therapy group (36 cases) and control group (33 cases). The therapy group were treated with Pingshen decoction 1 dose/d, bid po. The control group were treated with NephritisShu tablet, 6 tablet, tid po. 8 weeks was a course. Before and after treatment, we examine the serum level of HGF, Cys C and TGF-beta1 by ELISA and immunonephelometry, and compare with 30 cases of healthy control group. The study demonstrates that before treatment, the serum level of HGF in both groups were significantly lower than healthy control group (P < 0.01), but Cys C, TGF-beta1 were significantly higher (P < 0.01). After treatment, the serum level of HGF of both groups were increased. The serum level of HGF of therapy group were significantly higher than of control group (P < 0.01), but the serum level of Cys C and TGF-beta1 were significantly lower than control group (P < 0.01). The serum level of HGF was correlated negatively with Cys C,TGF-beta1. In control group, the UAER, urine beta2-MG and quantity of 24-hour urine protein were significantly decreased after treatment (P < 0.01). The index of urine of therapy group were significantly lower than control group (P < 0.01). Results indicate that test of serum level of HGF and Cys C,TGF-beta1 of diabetic nephropathy have important clinical significance. Pingshen decoction can effectively intervene in the serum level of HGF and Cys C, TGF-beta1 and index of urine.
