Objective To investigate the anti-tumor effects of total saponins,extracted from stems and leaves ofParispolyphyllavar.yunnanensis. Methods Taking mouse stomach carcinoma MFC cell line,human mammary cancer cell line(MCF-7)and human cervical carcinoma cell line(Hela),and their tumor-bearing mice as models,the antitumor activity was carried out in vitro and in vivo. CCK-8 assay was used to determine the inhibitory effect in vitro. The tumor-bearing mice model was induced by tumor cell vaccination in normal mouse forelimb left axillary subcutaneous and these mice were randomized into NS group,cytoxan group(30 mg/kg),saponins high-dose,medium-dose and low-dose groups(60,30 and 15 mg/kg). They were given intraperitoneal injection once a day for consecutive 15 days. The tumor inhibition rate and survival of the tumor-bearing mice were measured. Results Saponins,extracted from both aboveground and underground ofP.polyphyllavar.yunnanensis could significantly inhibit the growth of MFC,MCF-7 and Hela cells in time- and dose-dependent manners. The tumor weight in each drug treated group was significantly lower than that in the control group. Conclusion Saponins,extracted from both aboveground and underground ofP.polyphyllavar.yunnanensis have antitumor activity.

Objective:To explore therapeutic effect and safety of endovascular stenting on transient ischemic attack (TIA) caused by atherosclerotic vascular stenosis .Methods:A total of 100 patients with TIA caused by vascular ste-nosis in our hospital from Jan 2011 to Feb 2013 were enrolled ,and equally divided into combined treatment group (received endovascular stenting combined medication ) and routine treatment group (received medication treat-ment) .After 12-month treatment ,recurrence rate of TIA ,incidence rate of stroke and vascular stenosis rate before and after treatment were compared between two groups .Results:Compared with before treatment ,there was no significant change in all above-stated indexes after treatment in routine treatment group;were significant reduction in vascular restenosis rate [ (73.31 ± 12.76)% vs .(25.01 ± 5.73)% ] in combined treatment group ,and it signifi-cantly reduced than that of routine treatment group (74.33 ± 12.96)% ,P<0.01 both ;during the 12-month follow-up ,compared with routine treatment group , there were significant reductions in percentages of recurrent TIA (16.0% vs .2.0% ) and cerebral stroke (12.0% vs .0) in combined treatment group ,P<0.05 both Conclusion:En-dovascular stenting can significantly improve clinical therapeutic effect and prognosis in patients with atherosclerotic vascular stenosis ,and is worth clinical extension in some condition .

Objective To investigate the reproductive endocrine status of women with epilepsy at childbearing age and to systematically analyze the clinical features of reproductive endocrine disorders,especially polycystic ovarian syndrome (PCOS),to facilitate early detection and timely intervention.Methods In this study,scoring of anthropometry and physical signs,menstrul assessment,examination of sex hormone and pelvic ultrasound in women with epilepsy at childbearing age were performed,and the data such as overweight,central obesity,oligo/amenorrhea,luteinizing hormone (LH)/follicule-stimulating hormone (FSH),hyperandrogenism and polycystic ovary (PCO) were collected. The characteristics of their reproductive endocrine hormone disorders were analyzed statistically. Results The age of these patients was (22. 5 ± 7.0 ) years,and women younger than 30 years old and at their peak fertility accounted for 84. 89%. The prevalence rate of PCOS in women with epilepsy at childbearing age (12. 75% ) was significantly higher than that of ordinary women at childbearing age (7.2%) in China.Highly specific indicators for PCOS were hyperandrogenism (100%),LH/FSH ＞ 2 (93%) and oligo/amenorrhea (90%),whilst the highly sensitive indicators for PCOS were PCO (92%), oligo/amenorrhea (85%) and hyperandrogenism (54%). This study revealed statistically significant difference in LH,LH/FSH and testosterone (T) between PCOS group (LH: (10.24 ± 6.92) IU/L; LH/FSH;(2.20 ± 1.16);T: ( 1.07 ± 0. 35) ng/ml) and non-PCOS group ( LH: (4. 16 ± 2.62 ) IU/L; LH/FSH:( 0. 87 ± 0. 56 );T: (0. 46 ±0. 25) ng/ml,t = -3. 899,-4. 240 and -4. 918 respectively,all P ＜0. 01 ). Conclusions Hormone indices are objective indicators for the diagnosis of PCOS. In clinical practice,attention should be paid to height,weight,abodominal circumference,menstrul history and ultrasound examination of the ovary in women with epilepsy.When reproductive endocrine hormone disorders are suspected from clinical features,the sex hormones (T,LH,and FSH ) should be checked to allow timely detection and early interventions.

[Objective]This study was designed to identify the risk factors related with reproductive endocrinology disorder in Chinese women of child-bearing age with epilepsy.[Methods]The clinical data of 102 women with epilepsy were collected.The patient were grouped according to seven aspects(seizure onset age,seizure type,seizure frequency,duration of epilepsy,AED type,age of start AED therapy and duration of therapy)and the contribution of these factors in development of PCOS and its components were analyzed.[Results]The incidence of hyperandrogenemia in the patients with an early onset age(≤14 years old)was higher than the ones with an onset age＞14 years old.Onset age≤14 was the risk factor of hyperandrogenemia in logistic regression analysis.The incidence of a/oligomenorrhea,polycystic ovaries,hyperandrogenemia and PCOS in the valproate-treated women were 40.63%,50.00%,15.65%,and 34.38%,respectively,which were higher than the no-therapy group and nonvalproate treated group.Valproate therapy was the risk factor of PCOS and its components.[Conclusion]Valproate therapy was the risk factor of PCOS and its components in Chinese women of child-bearing age with epilepsy.Onset age≤14 was the risk factor of hyperandrogenemia.

Objective To investigate the protective effects of stilbene glycoside(2,3,5,4'-tetrahydroxy-stilbene-2-O-β-D-glucoside,TSG) on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced mice model of Parkinson's disease(PD).Methods Mice were randomly divided into the blank control group,the negative control group,the TSG high-dose group,the TSG low-dose group and the positive drug group(n=20 each).Mice were weighted daily to observe the changes of body weight,and mice motor and behavior function were tested by open field test.Level changes of α/β synuclein in brain cortex,cerebellum,midbrain,and hippocampal were detected by Western blot.Results Compared with the blank control group,the negative control group showed that the body weight was decreased (P ＜ 0.05).Compared with the negative control group,the body weight was increased in the TSG high-and low-dose groups and the positive drug group (P ＜ 0.05).The spontaneous behavior was impaired in the negative control group.Compared with the blank control group,the negative control group showed that the open field test showed traveled distance over a 10-min period was significantly shortened at 1 st,7th,28th days after testing(all P＜0.05).The trajectory of motor axons indicated that mice in the negative control group showed dyskinesia,but the groups of positive drug and high-and low-dose of TSG could reverse this dyskinesia.Compared with the blank control group,brain α/β synuclein protein levels were increased in the negative control group,and decreased in positive drug and TSG high-and low-dose groups (P ＜0.05).Conclusions Stilbene glycosides exert neuroprotective effects in MPTP-induced mice model of PD.
