OBJECTIVE:To observe therapeutic efficacy and side effect of perospirone in the treatment of elderly depression. METHODS:64 elderly patients with depression were randomly divided into paroxetine combined with perospirone group (drug combination group) and paroxetine group (single drug group) with 32 patients in each group. Both groups were given paroxetine 20-40 mg/d,and drug combination group was additionally given perospirone 4-8 mg/d. HAMD and CGI-SI were adopted to evalu-ate therapeutic efficacy after 8 weeks treatment,and side effect was evaluated with TESS scale;those were compared between 2 groups. RESULTS:After 8 weeks treatment,the effective rate of drug combination group and single drug group were 75.0% and 50.0%;there was statistical significance(P<0.05). There was statistically significant difference in HAMD and CGI-SI scores be-tween two groups(P<0.05). There was no statistically significant difference in the incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Small-dose of perospirone can improve therapeutic efficacy of paroxetine in the treatment of elderly depression with less side effect and good safety.

Objective: To clone the full length cDNA encoding diketide CoA synthase (DCS) gene which plays an important role in curcumin biosynthesis pathway in Amomum villosum, and to provide the basis for the further studies on biosynthesis and gene regulation of curcumin. Methods: According to the annotation of root transcriptome of A. villosum, primers were designed and cDNA of DCS gene was cloned from A. villosum by PCR. Results: The complete coding sequence of DCS gene was 1 170 bp and it encoded a protein of 389 amino acids. The deduced DCS amino acid sequence exhibited 96% identity to the DCS of Curcumae Longae and 66%-69% identity to the chalcone synthase (CHS) of Narcissus tazetta. Phylogenetic analysis on the amino acid sequence of DCS with those of other plants showed that DCS was closely related to Curcumae Longae. Conclusion: The DCS gene is cloned from A. villosum for the first time. This research lays a foundation for studying the gene expression pattern and regulatory functions of DCS in curcumin biosynthesis.

Objective The purpose of this paper is to study PGM1 genotyping by PCR RFLP.Method 300 unrelated individuals of Han were genotyped using PCR RFLP. The target amplificaton products of extron 4 and 8 of PGM1 gene were digested by Bgl II and Nla III respectively.The digested DNA fragments were typed by PAGE.Result This PGM1 RFLP system can discriminate 9 genotypes with Dp of 0 7450 in Han population.Compared with conventional PAGIEF, 1+2- and 1-2+ cant be differentiated and the rare genotypes also cant be detected by this method.The advantage of this method was PGM1 genotyping successfully in bloodstains stored for 25 years and with 0 1ng genomic DNA.PGM1 RFLP method is useful for forensic identification.

Objective:To explore mental health of students of military medical university Method:Based on understanding of help seekers in counseling, we selected grade-2 students in the fourth military medical university as our sample (n=374, male: 252, female: 122; 264 from army, 110 submitted by civil units) The research instruments included SCL-90 and EPQ Results:EPQ results showed, female had lower N, P scores, higher E score than male They also had higher score of phobia in SCL-90 than male, while male had higher scores of obsession, interpersonal sensitivity, and anxiety in SCL-90 than female Compared with students from one child family, students having siblings had higher P score, lower E score, and higher scores of depression, phobia, and psychotism in SCL-90 Civil students had lower N, P scores and higher E score than military students did They had also lower scores of obsession, interpersonal sensitivity, depression, anxiety, and psychotism in SCL-90 Conclusion: In students of military medical university, male, those from multiple children families and those from army have relatively poor mental health than their counterparts

Since the information supplied by the paternity testing of alleged parents was less than that of standard triplet parentage testing,so the paternity index (PI) calculating methods of standard triplet parentage testing was not suitable for calculating the PI value of alleged parents.In order to establish a more precise method for calculating PI value of alleged parents with STR typing results,the first thing is to summarize the standard triplet PI calculating formulas according to the Essen Mller theory.These formulas are 1/p,1/2p,1/p+q,1/2p+2q.This article reports a new PI calculating method in case of paternity testing of alleged parents.Compared with other methods,the new method for calculating Y value either considering random man and random female or considering the alleged father(mother)and random female(man).

The study is aimed to investigate the effect of plant growth regulators on yield and quality of the Salvia miltiorrhiza. The plant growth regulators was spraying on Salvia plants in July or August in field experiment, then the yield, ingredient content and the antioxidant activity were determined. The results showed that plant growth regulator 'Zhuanggenling' could increase the yield of Salvia with root-planting by 38.45%. Plant growth regulator 'Duoxiaozuo' could increase the yield of Salvia with seedling planting by 14.19%. Both plant growth regulator significantly reduced the antioxidant activity of Salvia in vitro, but they had no significant effect on active ingredient contents.

Objective To investigate the the distribution of Helicobacter pylori (H. pylori) vacA gentypes and the relationship between the presence of specific genotypes and clinical diseases in Zhejiang of China. Methods 262 Helicobacter pylori strains were colleted from 8 districts of Zhejiang,chromosome DNA was extracted and polymerase chain reaction (PCR) was carried out to determine the polymorphism of vacA and cagA with specific primers.PCR results were analyzed statistically according to their isolated original and clinical outcomes. Results VacA m1b, vacAm2 and vacAm1bm2 were found positive in 27.10%,4.89% and 4.20% of the 262 H.Pylori strains respectively. There was no significant difference in vacA genotypes among different districts of Zhejiang. 26.47%(27/102)of vacA m1b,66.67%(68/102) vacAm2 and 2.94%(3/102)vacAm1bm2 Helicobacter pylori strains were isolated from chronic gastritis; 29.41%(40/136)of vacA m1b,61.76%(84/136)vacAm2 and 3.68%(5/136)vacAm1bm2 Helicobacter pylori strains were isolated from Peptic Ulcer;and 16.67%(4/24)of vacA m1b,75.00%(18/24) vacAm2 and 4.17%(1/24) vacAm1bm2 Helicobacter pylori strains were isolated from gastric cancer; There was no significant difference in vacA genotypes among different clinical disease. Conclusion CagA+ and vacAs1/ m2 are predominant genotypes of H. Pylori in 8 districts of Zhejiang province. However, the relationship between vacA genotypes of H. pylori and the clinical disease can be identified in this study.

Objective To evaluate the efectiveness of using mesenchymal stem cells(MSCs)derived from HUCB(human umbilical cord blood)to a tissue engineered bioartificial nerve on bridging a 1 0 mm sciatic nerve gap.Methods The cord blood mononuclear cells were isolated by lymphocyte separation medium,purified and expanded with MesencultTM medium and acidic environment to produce adherent layer(MSCs).Thirty SD female rats were randomly divided into three groups.Group A:Human amnion tubes were seeded by HUCBMSCs together with fibrin sealant.Group B:Human amnion tubes were seeded only with fibrin sealant.group C:autografts.9 weeks later,a series of examinations were performed which included morphological,sciatic nerve function index,weight of gastrocnemius,histological staining and immunostaining of S100.Results The HUCB-derived mononuclear cells,when seeded in specific medium,gave rise to adherent cells (MSCs).At 9 weeks after the operations,all the examinations of group A was better than group B(P＜0.05).Conclusion HUCBMSCs can be isolated,purified, cultivated and expanded Mesencult~(TM) medium.HUCBMSCs can promote the nerve to regenerate in reparing the sciatic nerve gap.

Objective: To explore the effects of ginsenosides(GS) on learning,memory and activity of rats during sleep deprivation(SD).Methods: SD was induced in Sprague-Dawlay rats by employing "flower pot" technique.The rats were randomly divided into five groups according to the time of SD(0-96h),and every group was also divided into two subgroups: experimental group(E) and control group(C).Forced feeding of GS to the experimental rats for 5 d before the rats were deprived of sleep.Before and after SD immediately,the behaviors of rats were studied in "Y" maze test,step-down test and open-field test.Results: ①"Y" maze test: As compared with those of the controls,the accuracy of response of experimental groups increased significantly in 24h,48h,72h and 96h(P
