Objective To evaluate the safety and clinical efficacy of finasteride in treating patients with benign prostatic hyperplasia (BPH) during a 14-year period in a hospital.Methods Forty-one patients with BPH receiving finasteride 5 mg daily for the treatment from December 1994 to Febrary 2009 were included in the study. The base line and the end of study data of nocturia, prostate volume, serum creatine, complete blood count and serum prostatic specific antigen (PSA) were recorded. The acute urinary retention, surgical treatment and drug adverse reaction (prostate cancer or breast cancer) during the observation periods were recorded as well.ResultsAll the 41 cases took finasteride regularly for long-term medical therapy of BPH. At the end of this study, the average age of patients was (87.9±5.4) years old and the average duration of treatment was (141.1±27.1) months. The numbers of nocturia were 1.8±1.5 and 3.2±1.3 pre- and post- treatment, respectively (t= -4.52,P<0. 05). Before and at the end of the study, the prostate volumes were (44.9±26.6) ml and (42.8±31.3) ml, respectively(t=0. 33,P>0.05). Stratified study showed that, compared with the baseline data, the prostate volume was increased by 17.3 % in patients with prostate volume <25 ml(t= -0. 88 ,P>0. 05) ; the prostate volume was decreased by 17.2% in patients with prostate volume of 25-40 ml(t=2.59,P<0.05); the prostate volumes were (63.3±28. 9) ml and (62.6±36.5) ml pre- and post-treatment in patients with prostate volume > 40 ml, and there was no significant change(t= 0.07, P>0. 05). Before and after the treatment, the serum creatine levels were (96.8±18. 6) mol/L and (86.45±32. 3) mol/L, respectively(t= 1.79, P>0. 05) ; the white blood cell counts were (6.4±1.5) × 109 L and (6.0±1.7) ×109 L, respectively (t= 1.13,P>0. 05) ; and the PSA levels were (1.2±2.0) μg/L and (1.4±1.7) μg/L, respectively (t=-0. 49,P>0. 05). Three cases (7.3%) occurred acute urinary retention. There was no prostate cancer and breast cancer case, and no new adverse event occurred during long-time use of finasteride. Conclusions This retrospective study has demonstrated that the clinical progress of BPH can be controlled effectively by long-term administration of finasteride.

Objective To investigate influencing factors of perioperative myocardial injury in patients undergone percutaneous coronary intervention (PCI). Methods Ninty one patients with coronary heart disease (including stable angina and unstable angina) underwent PCI, the perioperative myocardial injury incidence were observed prospectively by monitoring the preoperative and postoperative high sensitivity troponin protein levels to investigate the influencing factors of perioperative myocardial injury by Logistic regression analysis. Results There were no statistically significance in perioperative myocardial injury incidence (62.5%vs 68.7%, P=0.618) and perioperative myocardial infarction incidence (29.2%vs 20.9%, P=0.411) between stable angina and unstable angina groups . These factors of perioperative myocardial injury in patients undergone PCI by Logistic regression analysis were analysed, and we found that the influencing factors were the application loading dose rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels and total stent length. Conclusion Application loading dose of rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels are related to perioperative myocardial injury reduction, whereas the total length of the stent is associated with an increased occurrence of perioperative myocardial injury.

Objective To investigate the effect of baseline Left-ventricular ejection fraction (LVEF) on the cardiac resynchronization therapy (CRT). Methods A retrospective analysis of patients with heart failure was performed. Fifty-four patients [aged (59.73 ± 11.61)years, 31 males, 23 females] who underwent CRT/CRTD were divided into 2 groups according to LVEF ( group A, LVEF≤ 35%; group B, LVEF > 35% ). NYHA class, LVEF,CRT respond rates and medical adverse event (MAE) due to worsening heart failure were detected at 3 and 12 months post-surgery. Results The score of NYHA class changing wasn′t different between these two group. Compared to group B, LVEF was markedly increased (5.08 ± 2.81)% vs (2.45 ± 1.80)%, P < 0.05;(5.38 ± 2.92)% vs (2.39 ± 3.53)%, P < 0.05)at 3 and 12 months post-surgery. Similarly, group A owned high CRT response rates(66.1% vs 33.9%, P < 0.05; 81.25% vs 47.83%, P < 0.05) at the both two time points. At 12 months post-surgery , LVED decreased and the MAE was similar in all groups. Conclusion Patients with EF≤ 35% have more increases in LVEF and own high CRT response rates post-CRT.

Background: The side effects of glucocorticoid in treatment of systemic lupus erythematosus (SLE) have been the focus of debate, and our preliminary study indicates that ginsenosides can enhance the efficacy of dexamethasone. Objective: To observe the effects of ginsenosides combined with prednisone in SLE patients. Design, setting, participants and interventions: A total of 60 SLE patients from Department of Rheumatology and Immunology, Changhai Hospital, Second Military Medical University, were randomly divided into treatment group and control group, with 30 patients in each group. Patients in the treatment group were given routine treatment with prednisone plus ginsenosides, while those in the control group were given routine treatment with prednisone plus placebo. They were all treated for 3 months. Main outcome measures: After three-month treatment, syndrome score in traditional Chinese medicine (TCM), total response rate and symptom improvement rate were measured and evaluated. Results: Twenty-eight cases in treatment group and twenty-seven cases in control group were included in analysis. The total response rates in the treatment group and control group were 89.28% and 66.67% respectively, and there was a significant difference between the two groups (P<0.05). After treatment, the TCM syndrome scores in the two groups were lower than those before treatment (P<0.01), and prednisone plus ginsenosides was better in decreasing the TCM syndrome score than prednisone plus placebo (P<0.05). The symptoms were improved in the treatment group as compared with the control group (P<0.05). Conclusion: Prednisone combined with ginsenosides can increase the clinical effective rate and improve the clinical symptoms of SLE patients.

The use of rnicroarrays of oligonucleotides or cDNA is considered to be a promising approach for DNA and RNA sequence analysis, diagnostics of genetic diseases, gene polymorphism studies and analysis of gene expression. To manufacture cDNA microarrays the samples were printed onto glass microscope slides treated with poly-L-lysine, and then the slides were processed by heat and UV light treatment to attach the cDNA sequence to the glass surface. But the immobilization efficiency of cDNA on the glass surface was low. A simple procedure for manufacture cDNA microarrays on a slide treated with 3-aminopropyltrimethoxysilane is described. The efficiency for attaching cDNA to the amino-modified slides is greater than that to the slides treated with poly-L-lysine. The cDNA microarray made by the amino-modified slides is stable for use in 80℃, 75 % humidity, 3 600Lx light, exposure in air, respectively.
