Objective:To observe the impact of compound glycyrrhizin combined with triamcinolone acetonide on clinical effects and immune function in the patients with oral lichen planus ( OLP) . Methods:Totally 100 patients with OLP were randomly divided into the control group (50 cases) and the study group (50 cases). The control group was locally injected with triamcinolone acetonide, and the study group was treated with compound glycyrrhizin tablets additionally. The treatment course was 4 weeks. Visual analogue scale ( VAS) and REU scoring system were used to assess pain and symptoms of OLP, the clinical effects and cellular immune function were compared, and the adverse reactions were recorded as well. Results:After the treatment, the VAS score and REU score respec-tively lower than those for the control group, and there were differents between the two groups (P<0. 05). The total effective rate was 84. 0% in the study group, which was higher than that in the control group (66. 0%) (P<0. 05). The percentage of CD3+ and CD4+ cells was increased, that of CD19+ cells and the ratio of CD4+/CD8+ were decreased, and there were significant differences be-tween the two groups (P<0. 05). The adverse reactions in both groups were mild. Conclusion:Compound glycyrrhizin combined with triamcinolone acetonide is effective for OLP and can improve the immune function in the patients.

Objective To evaluate the outcome of valvular surgery in the elderly. Methods Between 1993 and 2004, 4546 patients underwent cardiac valve operation at our hospital. 252 patients (5.5%)(147 males, 105 females) were 65 or older [mean age (67.9?2.9) years]. Rheumatic valvular disease presented in 201(79.8%) patients and non-rheumatic valvular disease in 51 (20.2%). 56.0% of patients were in New York Heart Association (NYHA) functional class Ⅲ-Ⅳ.63 (25%) patients had aortic valve replacement (AYR), 93 (36.9%) had mitral valve replacement (MVR), 42 (16.7%) had mitral valve repair (MVP), 47 (18.7%) had AVR + MVR/MVP, and 7 (2.8%) had isolated tricuspid repair or replacement.34 (13.5 % ) had concomitant coronary artery bypass grafting (CABG) . Results Results The operative mortality was 9.1%, and the tendency of decline was observed in recent 3 years. As compared with the patients aged 16 to 64 years, the duration of mechanical ventilation, stay in ICU and in hospital postoperatively was longer [(30.6?42.8)h vs. (24.1?45.0) h,P = 0.02, (60.1?101.2) h vs. (43.0?70.6) h, P = 0.00, (25.7?41.3) days vs. (19.6?14.4) days,P=0.00]. In this group, the morbidity of postoperative complications was significant higher than that of the patients aged 16 to 64 years (10.6% vs.6.4% , P = 0.01). Preoperative NYHA function class was an important factor for postoperative mortality. Multivariate logistic regression showed that concomitant coronary artery bypass grafting (CABG) , AVR+ MVR/MVP, and prolonged cardiopulmonary bypass time, prolonged aortic cross-clamping time, postoperative acute renal failure demanding dialysis were significant independent predictors of operative mortality. Conclusion The mortality of cardiac valvular surgery in the elderly is acceptable. It is characterized by higher morbidity of postoperative complications and prolonged duration of stay in hospital. Concomitant CABG, AVR + MVR/MVP, prolonged cardiopulmonary bypass time, prolonged aortic crossclamping time and postoperative acute renal failure were significant independent predictors of operative mortality.

0) and the correlation coefficient were low.The absence of intravesical occurrence of the cancer in solitary primary tumor cases was significantly less than that in the multiple ones ( P =0).The intravesical occurrence rate of the cancer elevated with the pathological stage of the primary cancer ( P =0.0039).92.5% of cases with initial concurrent involvement of the bladder have had the occurrence of bladder cancer within 2 years after surgical treatment. Conclusions The number and the stage of the primary tumor,with concurrent bladder involvement or not and the internal between the occurrence of the bladder cancer and the upper urinary tract cancer are the significant factors for prognosis,the coefficient correlation between the 4 factors being low.

Objective To evaluate the practicability and safety of 25-gauge (25G) transconjunctival sutureless vitrectomy system (TSV25G) and describe the preliminary experience. Methods Eighteen patients underwent TSV25G. The time of procedures of setting-up the three-port cannulae and closing the cuts were recorded. The pre- and post-operative ocular tension, visual acuity and complications were observed. Results The average time of setting-up the three-port cannulae and closing the cuts was 1 minutes 24 seconds and 32 seconds, respectively. The average preoperative ocular tension was 16.3 mm Hg(1 mm Hg=0.133 kPa); the average postoperative ocular tension at the first day, first week, and first month was 13.0, 15.9, and 16.4 mm Hg, respectively. The visual acuity before and one month after operation the was HM/20 cm～0.2 and HM/50 cm～0.6, respectively. No postoperative complication was found. Conclusion TSV25G may simplify the operation, minimize the surgical induced trauma, and decrease the operating time and the postoperative inflammatory response.

BACKGROUND: Disoprofol has anti-apoptosis impact so that it can protect the neurons from damage caused by ischemia. However, it needs further study on the mechanism of anti-apoptosis of it. OBJECTIVE: To investigate the effects of disoprofol to cell apoptosis and expression of apoptosis-associated gene in rats during reperfusion after global ischemia.DESIGN: A randomized controlled trial.SETTING: Department of Neurosurgery of Beijing Tiantan Hospital.MATERIALS: The experiment was conducted in Beijing Neurological Surgery Research Institute of Capital University of Medical Sciences during January 2003 to January 2004. A total of 23 adult male Wistar rats were randomly divided into ischemic group( n =9), disoprofol group( n =9) and sham operation group( n = 5).INTERVENTIONS: To prepare global ischemia-reperfusion model of rats. Disoprofol was injected into vein with dose of 1.5 mL/hour after reperfusion started in disoprofol group and lasted for 30 minutes. Five rats were selected from each group to be removed brain after reperfusion for 24 hours. Apoptosis rate and necrosis rate were detected by flow cytometer. Four rats selected from ischemic and disoprofol group were detected differential expression of apoptosis associated genes by gene chip combining image analysis techniques.MAIN OUTCOME MEASURES: ① apoptosis rate and necrosis rate; ②expression of apoptosis-associated gene detected by gene chip.RESULTS: The apoptosis rate[(7.01 ±0.79)% ] and necrosis rate[ ( 12. 80 ± 0. 92) % ] of neurons of hippocampus in disoprofol group were much lower than those of ischemic group [ (10. 89 ± 0. 80)%, (16. 67 ± 1.04)% ](P ＜ 0.01) . Compared with ischemic group, the three apoptosis associated genes including apoptotic prote ase activating factor 1 (APAF1), death effector domain containing testicular molecular mRNA(DEFT) and STM-2 were down regulated.CONCLUSION: Disoprofol can protect the brain and its mechanism might be related to the down regulation of three apoptosis associated genes including APAF1, DEFT and STM-2.
