OBJECTIVE:To detect curative mechanism of bushen huoxue huatan formula on polycystic ovarian syndrome (PCOS)model rats. METHODS:50 rats were randomly divided into normal control group,model control group,positive control group [rosiglitazone,3.0 mg/(kg·d)] and Bushen huoxue huatan formula high-dose,low-dose groups [7.5,5.0 g/(kg·d)],10 in each group. Except for normal control group,the PCOS model was induced by Poresky method in other groups. After modeling, normal control group and model control group were received normal saline intragastrically,medicine groups were received corre-sponding liquids intragastrically,once a day,for 22 d. After administration,the serum levels of testosterone (T),anti-mullerian hormone (AMH),insulin-like growth factor Ⅰ(IGF-Ⅰ),tumor necrosis factor-α(TNF-α) and the positive expression of trans-forming growth factor-β1(TGF-β1)in ovarian tissue were determined. RESULTS:Compared with normal control group,T,AMH, IGF-Ⅰ,TNF-αlevels in serum and TGF-β1 positive expression rate in ovarian tissue of rats in model control group were significant-ly increased(P<0.05);compared with model control group,T,AMH,IGF-Ⅰ,TNF-α levels in serum and TGF-β1 positive ex-pression rate of rats in ovarian tissue in other medicine groups were significantly decreased(P<0.05),and the indexes in Bushen huoxue huatan formula different doses groups were superior to positive control group(P<0.05). CONCLUSIONS:Bushen huoxue huatan formula can obviously reduce the T,AMH,IGF-Ⅰ,TNF-α levels in serum and TGF-β1 positive expression rate in ovarian tissue in model rats with PCOS,which may be one of the mechanisms of its treatment for PCOS.

OBJECTIVE:To explore the effects of Bushen huoxue huatan decoction on ovarian blood supply and form in model rats with polycystic ovarian syndrome(PCOS). METHODS:50 SD female rats were randomized into normal control group,model group,positive control group [rosiglitazone,3 mg/(kg·d)],Bushen huoxue huatan decoction low-dose and high-dose groups [5.0, 7.5 g/(kg·d)],with 10 rats in each group. Except for normal control group,PCOS model was induced in the other groups by Poresky method. After modeling,treatment groups were given relevant medicine intragastrically. The normal control group and mod-el group were given normal saline [10 mL/(kg·d)] intragastrically,once a day,for 22 days. After the end of administration,the rats were sacrificed. The microvessel density (MVD) was recorded. mRNA expression of vascular endothelial growth factor (VEGF), ovarian angiotensin Ⅱ receptor(Ang Ⅱ)type 1(AT1)and type 2(AT2),G-protein coupled receptor MAS were all detected in ovarian tissue of rats. The ovarian form was observed. RESULTS:Compared with normal control group,MVD of mod-el group and treatment groups were all increased,while mRNA expression of AT1,AT2 and MAS were down-regulated (P<0.05);cystic sinus sollicle,the decrease of granular cell layer,egg mother cells disappearance,the decrease of luteal tissue and other obvious pathological changes could be found in ovarian tissue of rats in model group. Compared with model group,above in-dexes of treatment groups were improved significantly,and the effects of Bushen huoxue huatan decoction low-dose and high-dose groups were better than that of positive control group (P<0.05). The pathological changes of ovarian tissue in treatment groups were all improved to certain extent. CONCLUSIONS:Bushen huoxue huatan decoction can improve ovarian blood supply,angio-genesis and ovulation in PCOS rats. It is beneficial to improve ovarian form.

Objective To establish a method of sperm DNA extraction in mixed stain by using DNase-Ⅰ purificationcombined with alkaline lysis method in forensic science.Methods 79 mixed stain samples of criminal cases were collected.Sperm DNA was extracted using the purification of DNase-Ⅰ binding alkaline lysis method.16 STR loci were genotyped with fluorescent multiplex amplification system.The typing results were compared with that of extracted using two-step differential extraction procedure.Results Of all 79 mixed stain samples,64 samples were genotyped successfully by using DNase-Ⅰ purification combined with alkaline lysis method while 57 samples were genotyped successfully with two-step differential extraction procedure.There was significant difference between two methods(P=0.039).The purification of DNase-Ⅰ binding alkaline lysis method had a higher success rate and lower cost than that of two-step differential extraction procedure.Conclusion Purification of DNase-Ⅰ binding alkaline lysis method can increase the typing success rate of the mixed stain samples.The method is simple,rapid and easy to be automated,and suitable for forensic identification test.

BACKGROUND:A large number of studies have shown that bone marrow mesenchymal stem cels (BMSCs) with differentiation ability can be used to treat kidney injury. Epimedium has good anti-inflammatory and immune restoration ability.
OBJECTIVE:To observe the effect of epimedium with BMSC transplantation on rat’s kidney disease caused by adriamycin nephrosis.
METHODS:Fifty rats were equivalently randomized to receive no treatment in control group, tail vein injection of normal saline plus intragastric injection of normal saline in model group, tail vein injection of BMSCs plus intragastric injection of epimedium decoction in combined group, tail vein injection of BMSCs in BMSCs group, and intragastric injection of epimedium decoction in epimedium group. Rat models of adriamycin nephrosis were made in the latter four groups through tail vein injection of doxorubicin hydrochloride, while rats in the control group were only given the same volume of normal saline. Twenty-four hours after modeling, rats in the latter four groups began to be given the corresponding treatments. Epimedium decoction was given in the combined and epimedium groups at a dose of 1 mL/d, for consecutive 1 week.
RESULTS AND CONCLUSION:Compared with the model group, mitigated kidney injury and reduced urinary protein level were found in rats undergoing BMSCs and/or epimedium decoction treatment; the levels of plasma albumin and catalase were significantly increased in the combined group and epimedium group, while the levels of serum cholesterol, triglycerides and malondialdehyde decreased; the mRNA expression of transforming growth factor β1 in the kidney tissues was dramaticaly declined in the combined group and BMSC group. To conclude, the combined use of epimedium and BMSCs is superior to their use alone in the treatment of kidney disease.
