OBJECTIVE:To investigate therapeutic efficacy and recurrence rate of vaginal administration of lactobacillus com-bined with chlorquinaldol-promestriene for senile patients with atrophic vaginitis. METHODS:150 senile patients with atrophic vag-initis were selected and divided into group A,B,C according to random number table,with 50 cases in each group. Group A was given Lactobacillus vaginal capsules,2 capsules,qd (at bedtime);group B given Chlorquinaldol-promestriene vaginal tablets,1 tablet,qd(at bedtime);group C given Chlorquinaldol-promestriene vaginal tablets,1 tablet,qd(at bedtime),and Lactobacillus vaginal capsules,2 capsules,qd,next morning,implanting into vagina. 3 groups received treatment for 18 d. Clinical efficacy, vaginal health score,vaginal symptom score and vaginal pH value were observed in 3 groups,and the occurrence of ADR and re-currence rate during follow-up period (12 months) were recorded. RESULTS:The total effective rate of group C was 94.00%, which was significantly higher than group A(72.00%)and B(74.00%),with statistical significance(P<0.05). Before treatment, there was no statistical significance in vaginal health score,vaginal symptom score and vaginal pH value among 3 groups (P>0.05). After treatment,vaginal health score of 3 groups were increased significantly,while vaginal symptom score and vaginal pH value were decreased significantly;and the improvement of above indexes in group C were significantly better than in group A and B,with statistical significance(P<0.05). No obvious ADR was found in 3 groups during treatment. The recurrence rate of group C during follow-up period(4.00%)was significantly lower than that of group A(18.00%)and group B(20.00%),with statistical significance(P<0.05). CONCLUSIONS:Vaginal administration of lactobacillus combined with chlorquinaldol-promestriene for se-nile patients with atrophic vaginitis can effectively relieve clinical symptoms and signs,improve vaginal cleanliness,regulate the lo-cal pH value and reduce the risk of recurrence,with good safety.

? amyloid protein(A?) including A?40 and A?42 are the important bioactive substances in vivo.Their toxic and beneficial attributes in the body depend on its concentration.The brain A? level is maintained by two balances under the physiological condition.The first balance is the generation involved in ?-secretase and ?-secretase and the degradation involved in neprilysin(NEP) and insulin-degrading enzyme(IDE) of A?. The second one is the balance between the receptor for advanced end glycation products(RAGE)-mediated influx and low-density lipoprotein receptor related protein 1(LRP1)-mediated efflux of A? across the blood-brain barrier(BBB).Breakdowning any one of the two balances would result in the aggregation and precipitation of A? in the brain,which is a crucial event in the pathogenesis of Alzheimer's disease(AD).This paper reviews the regulation of brain A? level under the physiological condition and the reducing strategies on the level of brain A? under the pathological condition for developing new drugs in the treatment of AD.

The present study visualized the knowledge map of research hotspots and changes of keywords by importing literatures from The American Journal of Clinical Nutrition (2000 ～ 2011) into CiteSpace.Analysis of the research hotspots (keywords),evolution of clinical nutrition,and front-line research based on tf-idf algorithm was then performed.

Objective To evaluate the pharmacokinetic parameters and bioavailability of puerarin in Yufeng Ningxin tablets in mice by determining dose-time curve and by comparing with the pharmacokinetics of puerarin injection.Methods NIH mice were randomized into different groups. 6 %HClO4 was used to precipitate plasma protein and the plasma concentration of puerarin in mice was determined by HPLC.The PK solutions 2.0 program,a non-compartmental model software,was applied to calculate the pharmacokinetic parameters and bioavailability.Results The main pharmacokinetic parameters of puerarin injection by i.v.in mice were:t1/2=98.359 min,CL=35.548 mL?min-1,AUC(0-∞)=281.3 ?g?min?mL-1;the main pharmacokinetic parameters of puerarin in Yufeng Ningxin tablets by o.p.were:t1/2 =35.562 min,CL=898.685 mL?min-1,Cmax=9.3 ?g?mL-1,Tmax=30 min,AUC(0-∞)=222.5 ?g?min?mL-1 ,F(bioavailability value)=3.95 %comparing to puerarin injection.Conclusion As compared with puerarin injection,the absorptive content of puerarin in Yufeng Ningxin tablets is very poor and the bioavailability is also low,indicating that enhancement of bioavailability of Yufeng Ningxin tablets will be beneficial to the clinical application.

Objective To determine the prevalence of female urinary incontinence among Chinese people in different areas. Methods A sampling survey of urinary incontinence was conducted on 668 female adults in a Beijing community,the Uygur region and a residential district inside the First Hospital of Peking University with questionnaire. Results The prevalence of female urinary incontinence was 46.5%(94/202) in the Beijing community,43.8%(134/306) in the Uygur Region and 40.6%(58/143) in the residential district inside the First Hospital of Peking University.The ratios of those who consulted with doctors to the separate surveyed population were 24.5%(23/94),29.1%(39/134),13.8%(8/58),respectively. Conclusions The prevalence of female urinary incontinence is similar in different population.Only a few of these women went to doctors,especially among the hospital staff and workers.

A new ionizing-radiation resistant strain WGR702 was isolated from arid soils which had been ra-diated. The strain WGR702 was Gram-positive and coccus, the diameter of the cell was 1.5 ?m～2.5?m.The strain WGR702 was pink-pigmented, motile, facultative anaerobe and non-spore forming. The range tem-perature and pH for strain WGR702 growth were 10℃～35℃ and pH 5.0～10.0 respectively. The strain WGR702 had a G+C content of 60.5 mol%. UV and gamma radiation survival curves showed the strain WGR702 had highly ionizing-radiation resistant. Phylogenetic analysis of the 16S rDNA gene sequences (EU315117) showed 94.79%～98.53% similarities with other recognized Serratia species. Primary charac-teristics that distinguish isolate WGR702 from the species of genus Serratia include the cells are spherical and Gram-positive. Based on the phenotypic, biochemical and physiological characteristics differences it is proposed that the new isolated strain WGR702 might be classified as a novel species of Serratia.

Chemical constituents of Swertia patens. The whole plant of air-dried Swertia patens was extracted with 90% EtOH. The water extract was suspended in H₂O and extracted with petroleum ether, EtOAc and n-BuOH, successively. The compounds were isola- ted and purified by column chromatography from the EtOAc fraction, and identified based on spectral analyses (MS, ¹H-NMR, ¹³C- NMR). Eighteen compounds were isolated and elucidated as 3, 4-dihydro-1H,6H,8H-naptho [1,2-c:4,5-c', d'dipyrano-1, 8-dione (1), angelone (2), gentiogenal (3), erythricin (4), erythrocentaurin (5), gentianine (6), swertiakoside B (7), swertiamarin (8), 2'-O-actylswertiamarin (9), amarogentin (10), 1, 3, 5-trihydroxyxanthone (11), 1, 3-dihydroxy-5-methoxyxanthone (12), 1-hydroxy- 2, 3, 5-trimethoxyxanthone (13), gentiocrucine (14), 3-hydroxyphenylketone (15), n-hexacosyl ester 4-hydroxy-trans-cinnamate (16), n-hexacosyl ester 4-hydroxy-cis-cinnamate (17), and cholest-4-en-3-one (18). Compounds 1-7, 9-18 were obtained from S. patens for the first time.
