There was positive effect using group therapy for the clients.ConclusionsThere are many factors such as emotion, human relations, social supports, and self-esteem related with isolation. Group therapy is an effective rehabilitation therapy for isolation.

Objective To explore the relationships among college students' trait anger,violent attitude and aggressive behavior.Methods A total of 991 college students were surveyed with the Trait Anger Scale,the Violent Attitude Questionnaire and the Aggression Questionnaire.Results (1)College students' scores on trait anger,violent attitude and aggressive scales were 17.99±3.94,3.52±2.20 and 70.12±14.67,respectively.(2) There were significant correlations among college students' trait anger,violent attitude and aggressive behavior(r=0.172-0.835,P<0.01).(3) Trait anger had a direct impact on aggressive behavior,as well as indirect effects through violent attitude.The direct effect of trait anger on aggressive behavior was 0.53,the indirect effect of violent attitude was 0.13,the total effect was 0.66,and the indirect effect was 20%.(4)The experience of parenting violence moderated the mediating effect of voilent attitude,and violent attitude moderated trait anger and aggression in those who didn't experience parenting violence(β=0.28,P<0.01),while the mediating effect was not significant in those who experienced parenting violence(β=-0.24,P=0.23,SIE=-0.166,P=0.28).Conclusion Violent attitude partially mediates trait anger and aggressive behavior,which is moderated by experienced parenting violence.

AIM:To approach the effects of Bacille Calmette-Guerin(BCG)on immunological function of infants with bronchiolitis in vitro. METHODS: The monocytes were segregated from the peripheral blood of infants with acute bronchiolitis and healthy infants as control. The cytokines of IL-10 and IL-12 were measured by ELISA after interfered with different concentrations of BCG in vitro. IL-4, produced by lymphocytes treated with the cultural supernatant of BCG-stimulated monocytes were determined by ELISA. Acute bronchiolitis infants and health children treated with normal saline were as control. RESULTS: BCG stimulated IL-10 and IL-12 production in a dose response manner in a certain concentration range. The higher level of IL-10 was observed when BCG concentration reached 50 ?L/mL, while IL-12 had no significant increase. The level of IL-4 was markedly decreased compared with pre-treatment (P

Objective To discuss the efficacy and safety analysis of different doses of low molecular weight heparin combined with hormone in the treatment of refractory nephrotic syndrome.Methods 60 cases of patients with refractory nephrotic syndrome in our hospital from January 2014 to January 2016 were selected,According to the random number table,60 patients were divided into high,medium and low dose of low molecular weight heparin group and control group,control group were treated with hormonal therapy,the high,medium and low dose of low molecular weight heparin group were injected low-molecular-weight heparin calcium on the basis of the control group,twice daily,once daily and every other day,respectively.Results After treatment,the clinical total effective rate of the high,medium and low dose group and control group patients was 14(93.3%),12(80.0%),10(66.7%) and 9(60.0%)respectively,the total efficiency of the high dose group was significantly higher than that of the control group(P<0.05),while there was no significant difference among control,medium and low dose group.The 24 h urine protein quantitation,ALB and Cr in high dose group improved better than those in medium and low dose group(P<0.05).The TG,TC and LDL in high dose group improved better than those in control group(P<0.05). The prothrombin time(PT)and activated partial thromboplastin time(APTT)in high and medium dose group were longer than those in control group(P<0.05),while fibrinogen(FIB)was lower(P<0.05).The PT in low dose group was longer than control group(P<0.05),while there was no significant difference in other coagulation indicators compared with control group.The APTT in high dose group was longer than low dose group(P<0.05).There was no obvious adverse reactions among each dose group.Conclusion The clinical curative effect in different doses of low molecular weight heparin combined with hormone in the treatment of refractory nephrotic syndrome is better,which could be significantly improved in patients with hypercoagulable state,especially effect of high dose group is more obvious.

Objective To investigate the mechanism of apoptosis induced by endoplasmic reticulum stress during sepsis.Methods Septic model of H9C2 cells was established by lipopolysaccharide (LPS).CHOP mRNA,mitochondrial membrane potential (MMP) and apoptosis were assessed by real-time PCR,flow cytometry respectively at LPS administration 24 h with or without salubrinal (inhibitor of endoplasmic reticulum stress).Results The expression of CHOP mRNA and apoptosis were upregulated,but MMP was decreased after LPS exposure 24 h compared with control group[2.40 ±0.30 vs 1.00 ±0,(16.58 ±2.71) ％ vs (3.85 ± 1.07) ％,1.07 ± 0.33 vs 2.62 ± 0.51,P ＜ 0.05).Compared with LPS group,salburinal pretreatment decreased LPS-induced upregulation of CHOP mRNA (1.60 ± 0.23 vs 2.40 ± 0.30,P ＜ 0.05),meanwhile,salburianl alleviated MMP(1.85 ± 0.31 vs 1.07 ± 0.33,P ＜ 0.05) and LPS-induced apoptosis [(6.05 ± 1.48) ％ vs (16.58 ± 2.71) ％,P ＜ 0.05].Conclusion Salubrinal plays a cytoprotective role against apoptosis induced by LPS through inhibition of CHOP mRNA,which leads to mitochondrial impairment.Endoplasmic reticulum stress may induce apoptosis via mitochondrial pathway in the septic model of H9C2 cardiomyocytes.

Objective To establish a method of isolating and cultivating rat bone marrow mesenchymal stem cells (MSCs) in vitro and the biological characteristics thereof.Methods MSCs were isolated and purified from the bone marrow of rat by density gradient centrifugation and by adhering to the culture plastic.After successive subculture and amplification,the growth curve was drawn.The morphology of MSCs was observed in primary and passage culture under inverted microscope.The cells surface antigens of CD29,CD38,CD44 and CD45 were detected through flow cytometer.Results Cultured primary MSCs were spin dle-shaped and had a typical fibroblast-like morphology,proliferated in colonies.After a series of passage,the attached cells became morphological homogeneous and proliferated quickly.The growth curves of passage 1,3 and 5 were quite similar.The surface marker identification showed that CD44 and CD29 were positive,but CD45 andCD38 were negative.Conclusion The MSCs can be successfully isolated,cultured and purified from rat bone marrow through density gradient centrifugation,adherent property and subculture.MSCs can greatly proliferate after a short period of culture in vitro.The MSCs can be used as a potential cell source for tissue engineering.

Objective To investigate mediate role of coping strategy between stressful life events and negative emotions which anxiety and depression are included.Methods Questionnaires of psychosocial stress survey for groups (PSSG),Simple Coping Style Questionnarire(SCSQ),Selfrating Anxiety Scale (SAS) and Selfrating Depression Scale(SDS) were used to examine 1 764 young servicemen.Results Correlation analysis showed that there existed negative correlations between positive coping and stressful life events,passive coping,anxiety,depression(r=-0.080～-0.304,P＜0.05).And correlation analysis also showed there existed positive correlations among the other variables(r=0.230 ～ 0.756,P＜0.05).There existed partly mediating effect of positive coping,passive coping between stressful life events and negative emotions.The standardized total effect of life events to anxiety was 0.302.Mediating effects of positive coping and passive coping were 0.033,0.044.The standardized total effect of life events to depression was 0.230,mediating effects of positive coping and passive coping were 0.051,0.029.Conclusion Coping strategy is an important mediator between stress and negative emotions such as anxiety and depression.

Objective To explore the influence of fasudil on plasma hydrogen sulfide(H2S)and N-terminal B-type natriuretic peptide( NT-proBNP) in patients with chronic pulmonary heart disease.Methods According to the digital table,102 patients with chronic pulmonary heart disease were randomly divided into the observation group and the control group, each group in 51 cases.The patients in the control group were treated through the conventional treatment,while the patients in the observation group were treated through the conventional treatment plus fasudil. They were treated for 14 days.The mean pulmonary artery pressure( MPAP) ,plasma H2 S and NT-proBNP were detec-ted.Results After treatment,the total effective rate in the observation group was 96.1%,which was higher than 86.3%in the control group(χ2 =4.046,P<0.05).MPAP in the two groups of patients were significantly decreased, and the observation group decreased more significantly than the control group(t=7.246,P<0.05).After treatment, plasma H2S were significantly higher,and the observation group increased more significantly(t=2.856,P<0.05), plasma NT-proBNP in two groups after treatment were significantly reduced,and the observation group decreased sig-nificantly(t=10.706,P<0.05).Conclusion Fasudil can be significantly improved plasma H2S and NT-proBNP in patients with chronic pulmonary heart disease.
