A total number of 2221sera collected from different kinds of subjects , i.e.patients with various stages of schistosomiasis. normal individuals, persons with other parasitic diseases or non-parasitic diseases, were detected with Dot Immunogold Filtration Assay (DIGFA) using anti-SVLBP IgG as capturig antibody. Positive rate of 70 sera from patients with acute schistosomiasis was 100%, and that of 307 sera with chronic schistosomiasis was 68.4% .None of 200 sera from normal individuals showed false positive reaction. No obvious cross reaction was found in sera from other parasitic/non-parasitic diseases except sera from patients with paragonimiasis.2 batches of sera were detected with DIGFA by single-blindness method. Results showed that sensitivities to chronic schistosomiasis were 69.4% and 68.9%, and 100% to acute schistosomiasis while specificities were 98.9%-99% .508 samples from residents in endemic areas were tested with DIGFA and Kato-Katz. Positive rate of circulating arrtigen was 20.9% with DIGFA while 65 samples were positive with stool examination.46 samples were positive both by DIGFA and by Kato-katz.The coincidental rate was 70.8% .These results indicated that DIGFA showed sensitive and specific in the detection of circulating antigen. It will be useful in mass application and vahuable in epidemiological stuvey.

A rapid, sensitive and simple liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for the simultaneous determination of yogliptin and its metabolite in Wistar rat plasma. Linagliptin and dexamethasone were chosen as the internal standards of yogliptin and its metabolite, (R)-8-(3-hydroxypiperidine- -yl)-7-(but-2-yn-1-yl)-1-((5-fluorobenzo[d]thiazol-2-yl)methyl)-3-methyl- H-purine-2, 6 (3H, 7H)-dione, respectively. After a simple protein precipitation using acetonitrile as the precipitating solvent, both analytes and ISs were separated on a Grace Altima HP C18 column (2.1 mm x 50 mm, 5 microm) with gradient elution using methanol (containing 0.1% formic acid, 4 mmol x L(-1) ammonium acetate)-0.1% formic acid (containing 4 mmol x L(-1) ammonium acetate) as the mobile phase. A chromatographic total run time of 4.4 min was achieved. Mass spectrometric detection was conducted with electrospray ionization under positive-ion and multiple-reaction monitoring modes. Linear calibration curves for yogliptin and its metabolite were over the concentration range of 0.5 to 500 ng x mL(-1) with a lower limit of quantification of 0.5 ng x mL(-1). The intra- and inter- assay precisions were all below 14%, the accuracies were all in standard ranges. The method was used to determine the concentration of yogliptin and M1 in Wistar rat plasma after a single oral administration of yogliptin (27 mg x kg(-1)). The method was proved to be selective, sensitive and suitable for pharmacokinetic study of yogliptin and M1 in Wistar rat plasma.

Objective To investigate the relationship among stressful life events ,social support and depression through researc‐hing a large number of Chinese army men ,then discovered the social psychological mechanism of the depression .Methods 11 ,400 officers and soldiers were tested with three scales ,the center for epidemiologic studies depression scale ,life events scale and social support scale .The differences between groups were determined with the variance ,SPSS 18 .0 software and AMOS7 .0 were used to analyse and build model .In addition ,we built the path model of life events and social support on depression with AMOS 7 .0 soft‐ware .Results (1)There is a significant positive correlation between Chinese soldiers depression levels and life events (r=0 .382 , P<0 .01) .(2) There is a significant negative correlation between Chinese soldiers depression levels and the social support (r= -0 .379 ,P<0 .01) .(3) It was established the path model of life events ,the social support and depressive symptom level .Con‐clusion Depressive symptom is related to the military life events ,which may predict the occurrence of the depression .Moreover ,so‐cial support ,a protective factor for mental health ,can relieve the depression of officers and men .

ObjectiveTo study the effect of adaptive group psychological training on mental quality and emotion of soldiers.MethodsA total of 48 soldiers ( experiment group) received group psychological training and read a textbook,Mental Quality Training for soldiers,for 3 months,and the other 45 soldiers served as control group.Armyman mental quality inventory (AMQI),self-rating depression scale (SDS) and state-trait anxiety inventory(STAI) were employed to evaluate the mental quality and emotion of soldiers before and after training.All data were analyzed by paired-sample t test.Results ①As compared with pre-training,the AMQI scores of training group increased significantly in bravery ( 71.50 ± 9.59 ),self-confidence ( 68.24 ± 8.36 ),aptitude ( 74.54 ± 10.81 ),loyalty(75.29 ± 8.08 ) and general score ( 359.07 ± 20.30 ) (P ＜ 0.05,P ＜ 0.01 ) ; and no significant difference were found in those of control group(P ＞ 0.05 ).②When compared with pre-training,the scores of SDS (39.00 ±8.38),SAI(40.14 ±9.92),TAI(41.16 ±7.47) and STAI(81.30 ± 12.52) of training group decreased significantly (P ＜ 0.05,P＜ 0.01 ) ; and no significant difference was found in those of control group(P ＞0.05 ).ConclusionGroup psychological training can improve mental quality of soldiers,which is helpful to relax anxiety and depression of soldiers.

Objective To investigate the social support characteristics of Chinese military men and their relationship with depression.Methods A total of 10,505 officers and soldiers from navy,army,air force,and armed police was performed the questionnaire survey by using the Military Men Social Support Rate Scale.The SPSS18.0 software was used for conducting the data statistical analysis.Results High utilization rate existed in the Chinese military men.The help almost could be gotten from the organization or relatives and friends when facing the difficulties;the social support of armed police was higher than that of army,navy and air force;The subjective support of officers was higher than that of soldiers and sergeants;the objective support were lower than those of officers and soldiers;the subjective support and support availability in the soldiers aged below 20 were higher than those in soldiers aged above 20.The social support of military men showed a significantly negative correlation with depression(r=0.376,P＜0.01).Condusion The higher the social support of military,the smaller the suffering from depression.

Objective To investigate the expression of microRNA-152 in hepatocellular carcinoma, and analyze the correlation of miR-152 expression with the clinicopathological characteristics of hepatocellular carcinoma(HCC) patients. Methods Real-time PCR was used to detect the expression of miR-152 in tissue specimens from HCC and the adjacent non-cancerous hepatic tissues collected from 56 patients who underwent surgical treatment for primary HCC. The association between the expression of miR-152 and the clinical pathological characteristics and prognosis of HCC patients was analyzed. Results The relative expression of miR-152 in hepatocellular carcinoma and corresponding adjacent non-carcinoma tissues were 0.616±0.041 and 0.768±0.042 (P=0.011). The expression of miR-152 was significantly associated with TNM stages (P=0.042), tumor differentiation (P=0.035), metastasis (P=0.048) and venous invasion (P=0.042). There was no significant association between the miR-152 expression and gender, age, AFP level, tumor number or tumor grade. The OS (P=0.035) and PFS (P=0.012) in the low miR-152 expression group were obviously shorter than those in the high miR-152 expression group. Multivariate Cox regression analysis showed that the low expression of miR-152, tumor recurrence and pathological classification were significant independent prognostic factors for the prognosis of hepatocellular carcinoma patients. Conclusion The expression of miR-152 is decreased in hepatocellular carcinoma tissues, and the low expression of miR-152 is significantly associated with TNM stages, tumor differentiation, metastasis, venous invasion and the prognosis of HCC patients.
