OBJECTIVE:To observe the efficacy and safety of Compound sabal berry tablet combined with tamsulosin in the treatment of benign prostatic hyperplasia complicated with urinary obstruction. METHODS:86 patients with benign prostatic hyper-plasia complicated with urinary obstruction were randomly divided into control group(43 cases)and observation group(43 cases). Control group orally received 0.2 mg Tamsulosin hydrochloride orally disintegrating sustained-release tablet,once every evening. Observation group additionally received 500 mg Compound sabal berry tablet before a meal,3 times a day. 4-week was regarded as 1 treatment course,and it lasted 3 courses. During the treatment,all patients in the two groups ate light food,avoiding spicy and bland food. The clinical efficacy,TCM symptom scores,interleukin-8 (IL-8),interleukin-10 (IL-10),tumor necrosis factor α(TNF-α),maximum flow rate(Qmax),post-void residual(PVR),the International Prostate Symptom Score(IPSS)scores before and after treatment and the incidence of adverse reactions in the 2 groups were observed. RESULTS:The total effective rate in ob-servation group was significantly higher than control group,the difference was statistically significant(P<0.05). Before treatment, there were no significant differences in the TCM symptom scores,Qmax,PVR,IPSS scores,IL-8,IL-10 and TNF-α between 2 groups (P>0.05). After treatment,TCM symptom scores,IPSS scores,IL-8,IL-10,TNF-α and PVR in 2 groups were signifi-cantly lower than before,and observation group was lower than control group,Qmax was significantly higher than before,and obser-vation group was higher than control group,the differences were statistically significant (P<0.05). And there were no severe ad-verse reactions during treatment. CONCLUSIONS:The efficacy of Compound sabal berry tablet combined with tamsulosin is superi-or to tamsulosin alone in the treatment of benign prostatic hyperplasia complicated with urinary obstruction,it can reduce the in-flammatory reactions and residual urine,with good safety.

AIM:To observe the effect of supplementing bilirubin on the anti-oxidative stress ability of red cell membrane in training rats through establishing animal models of high-intensity training. METHODS:The experiment was performed in the physiological laboratory of Physical Institute of Jiangxi Normal University from December 2004 to January 2005.①After one week of adaptive feeding,24 male SD rats were randomly divided into quiet control group,high intensity sports training and physiological saline group(training group),high intensity sports training and bilirubin group(training and supplementing group)with 8 animals in each group.②The training group and the training and supplementing group did the running on the platform with the slope of 0?at the first three weeks and 5?at the fourth week,6 days every week expect Sunday.The training and supplementing group was intragastrically infused with bilirubin by 40mg/kg body mass at 17:00-18:00 after training every day,and the other groups were given physiological saline,six times every week.Anticoagulatory blood about 2mL of heparin was harvested to prepare red cell membrane sample and measure the relevant indexes on the 4~(th)Sunday.③The serum total bilirubin level was determined using automatic biochemical analysis instrument;the malondialdehyde(MDA)and glutathione peroxidase(GSH-Px)of red cell membrane by TBA;the activity of superoxide dismutase(SOD)of red cell membrane using the method of Xanthine oxidase.All the treatment for animals was based on the ethical standards. RESULTS:All 24 rats were involved in the result analysis.①The serum total bilirubin level in training group was lower than quiet control group(P0.05).②The MDA of the red cell membrane in the training group was higher than the control and training and supplementing group(P0.05).③The activity of SOD in training group was lower than quiet control group(P0.05),but the training and supplementing group was higher than the control group and the training group(P

Objective To explore the relationship between methylene tetrahydrofolate reductase (MTHFR) gene polymorphism and homocysteine (Hcy),and further to investigate their correlation to coronary heart disease (CHD) in females.Methods This study involved 29 premenopausal women with CHD,57 postmenopausal women with CHD,50 men with CHD and 46 postmenopausal women with non-CHD.All patients underwent coronary angiography.The patients' gender,age,history of hypertension,diabetes and smoking were recorded.The plasma Hcy level,blood lipids and MTHFR gene polymorphism were examined.Results The level of Hcy in postmenopausal women with CHD was (18.11±7.21)μmol/L,which was significantly higher than (15.01±6.53)μmol/L in premenopausal women with CHD,(12.98±5.46)μmol/L in postmenopausal women with non-CHD group and (14.32±6.01)μmol/L in men with CHD group (t=5.23,3.65,5.08,all P<0.05).The frequency of the MTHFR TT genotype in postmenopausal women with CHD was 28.1% which was significantly higher than postmenopausal women with non-CHD(17.4%)(χ2=5.13,P<0.05),but there was no statistically significant difference with the other two groups.The plasma Hcy level in patients with TT genotype was significantly higher than that with CT or CC genotype in all groups.Multivariate logistic regression analysis showed a significant positive correlation in Hcy and TT genotype.Multivariate logistic regression analysis showed that smoking,Hcy,hypertension and diabetes were independent risk factors for CHD.The odds ratios(OR) of Hcy for CHD was 2.601 (95% confidence interval,1.326 to 5.745).Conclusion Hcy may be an independent risk factor for CHD in females.MTHFR C677T genotype is significantly associated with hyperhomocysteinemia,and its mutation frequency increases significantly in patients with CHD,but MTHFR mutation is not related with the incidence of CHD.
