Objective To study the effect of curcumin on the expression of inflammatory factors in model rats with chronic prostatitis/chronic pelvic pain syndrome(CP/CPPS) type Ⅲ.Methods The rats were randomly divided into following groups: sham-operated group(sham), CP/CPPS model group(model), curcumin 50 mg group(cur-50 mg) and curcumin 100 mg group(cur-100 mg) and p38 inhibitor group(SB203580).Drug was given to each treatment group for 12 days by intraperitoneal injection.The levels of TNF-α, p38, COX-2 mRNA was measured by Real-Time PCR.The expressions of TNF-α and COX-2 proteins were measured by immunohistochemistry.The levels of p38, p-p38 and NF-κB proteins were detected by Western blot.Results NF-κB, p-p38, TNF-α, COX-2 proteins and TNF-α, p38, COX-2 mRNA in model group were higher than those in the sham group (P<0.01);cur-100 mg group and SB203580 group could significantly relieve these change in the model group (P<0.01);COX-2 mRNA and protein in cur-100 mg group decreased more than that in SB203580 group;p-p38 was positively correlated with NF-κB in curcumin groups and SB203580 group compared with model group (P<0.01).Conclusions Curcumin can reduce the expression of inflammatory cytokines NF-κB, TNF-α, COX-2 and p-p38 in rats with CP/CPPS type Ⅲ.

Objective To observe the characteristics of vertical cast-off bloodstain pattern by different hitting-tools. Methods The regular hitting tools, a kitchen knife, a dirk, a plane set-hammer and an iron pipe, were selected. At a distance of 30 cmaway fromthe wall, the hitting tool with 5 mL fresh chick-en blood made the cast-off bloodstain fromtop to bottom. Then the holistic distribution characteristics ( length , width and density ) of cast-off bloodstain and morphology characteristics ( length , width and contact angle) of first single cast-off bloodstain were analyzed. Results The distribution length of cast-off bloodstain formed by dirk was minimum( P<0 .05 ) . The distribution width of cast-off bloodstain formed by kitchen knife was minimum(P<0.05). Except the pair of kitchen knife and plane set-hammer, the distribution density between each two tools had statistical differences (P<0.05). The length of first single cast-off bloodstain formed by plane set-hammer was longest compared (P<0.05). The width of first single cast-off bloodstain had statistical differences between kitchen knife and plane set-hammer, and between dirk and plane set-hammer (P<0.05). Conclusion The type of hitting tool could be inferred by the specific characteristics of cast-off bloodstain pattern formed by every specific type of hitting tool in crime scene.

OBJECTIVE:To optimize the formulation of azithromycin sustained-release vaginal suppository(ASVS).METHODS:The ASVS was prepared using S-40 as suppository base,HPMC as sustained-release material and glycerine as humectant.The formulation of ASVS was optimized by orthogonal design with accumulated release percentage and hardness as indexes and the amount of 8% HPMC and glycerol as factors;meanwhile,a verification test and the fitting of in vitro drug release model were performed.RESULTS:The optimized formulation ASVS was as follows:azithromycin 6 g,8% HPMC 23.52 g,glycerol 29.40 g,ethanol absolute 3 g,ethylparaben 0.59 g,and S-40 294 g.Three batches of suppositories prepared under the optimized formulation reached a mean content of 99.5%,with hardness up to the standard,showing good reproducibility and homogenicity in drug release in vitro.The accumulative release rates of all samples were greater than 98% at 180 min,and the release dynamics in vitro were in line with Higuchi equations.CONCLUSION:The optimized ASVS is feasible in formulation,stable and reproducible in preparation technology and up to the standard for sustained-release preparation.

Because of the high morbidity and mortality rate,cardio-cerebrovascular diseases,including cerebral embolism, cerebral hemorrhage,cerebral vasospasm and myocardial infarction,have become main diseases threatening human health. Tradition-al chinese medicine(TCM)holds that the basic pathogenesis is Qi imbalances,which could be improved by benefiting Qi and promot-ing blood circulation. The compatibility of Radix astragali and Radix salviae miltiorrhiae are particularly suitable for treating the car-dio-cerebrovascular system diseases by improving Qi deficiency and blood stasis. This paper focuses on the application of Radix astrag-ali,Radix s. miltiorrhiae and their compatibility for treating the cardio-cerebrovascular system diseases. Moreover,our research would offer valuable references for the development of new drugs related to the treatment of cardio-cerebrovascular system diseases.

A complete explanation of the new idea,grounds,spirit,inner-contradiction of the 3 major documents in the new framework of epileptic knowledge re-defined by International League Against Epilepsy was made in accordance with the International League Against Epilepsy original articles.And the different recognition about them nowadays existed among our nerologists was also deeply explored.

OBJECTIVE:To determine the content of ?-schizandrin,one of the effective ingredients,in Shuangjia Wuling capsules METHODS:The RP-HPLC method was performed with YWG C18 column(4 6mm?250mm) The mobile phase consisted of methanol-water(72∶28) The detecting wavelength was 254nm RESULTS:The calibration curve for ?-schizandrin was linear in the range of 0 0 207～0 4 130mg/ml(r=0 9 999) The average recovery was 97 68% with RSD=1 85% CONCLUSION:The method is simple,rapid and reliable for quality control of the capsules

OBJECTIVE: To observe the characteristics of vertical cast-off bloodstain pattern by different hitting-tools. METHODS: The regular hitting tools, a kitchen knife, a dirk, a plane set-hammer and an iron pipe, were selected. At a distance of 30 cm away from the wall, the hitting tool with 5 mL fresh chicken blood made the cast-off bloodstain from top to bottom. Then the holistic distribution characteristics (length, width and density) of cast-off bloodstain and morphology characteristics (length, width and contact angle) of first single cast-off bloodstain were analyzed. RESULTS: The distribution length of cast-off bloodstain formed by dirk was minimum (P < 0.05). The distribution width of cast-off bloodstain formed by kitchen knife was minimum (P < 0.05). Except the pair of kitchen knife and plane set-hammer, the distribution density between each two tools had statistical differences (P < 0.05). The length of first single cast-off bloodstain formed by plane set-hammer was longest compared (P < 0.05). The width of first single cast-off bloodstain had statistical differences between kitchen knife and plane set-hammer, and between dirk and plane set-hammer (P < 0.05). CONCLUSION The type of hitting tool could be inferred by the specific characteristics of cast-off bloodstain pattern formed by every specific type of hitting tool in crime scene.
