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 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 study effects of strengthened atorvastatin treatment on homocysteine( Hcy) and N-terminal B-type natriuretic peptide( NT-proBNP) in patients with non-ST-segment elevation acute coronary syndrome. Methods 120 patients with non-ST-segment elevation acute coronary syndrome were randomly divided into the two groups,the observation group(n=60 cases) and the control group(n=60 cases).The patients in the observation group were treated through the basis of conventional therapy plus atorvastatin 40mg/night treatment,while the patients in the control group were treated through the basis of conventional therapy plus atorvastatin 20mg/night treatment. They were all treated for two months.Plasma Hcy and NT-proBNP were detected before and after treatment.Results Hcy in the observation group and the control group before treatment were ( 25.5 ±8.6 )μmol/L and ( 26.3 ± 9.1)μmol/L,respectively,(10.3 ±4.7)μmol/L and (16.9 ±7.1)μmol/L after treatment.NT-proBNP in the obser-vation group and the control group before treatment were (374.7 ±39.2)ng/L and (359.6 ±36.1)ng/L,respective-ly,(127.4 ±15.3)ng/L and (237.1 ±24.3)ng/L after treatment.After treatment,plasma Hcy and NT-proBNP were significantly reduced than those before treatment and after treatment(P<0.05).During follow-up,the two groups showed no elevated liver enzymes and muscle enzymes and lead to withdrawal from happening.Conclusion Strength-ened atorvastatin treatment can significantly reduce Hcy and NT-proBNP in patients with non-ST-segment elevation acute coronary syndrome.

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.

Objective To detect the expression of pituitary tumor transforming gene (PTTG) in estrogen-induced rat prolactinoma and various types of human pituitary adenomas to explore the role of PTTG in pituitary tumor oncogenesis. Methods Rat model of estrogen-induced prolactinoma was set up, and PTTG mRNA level in rat prolactinoma was measured by RT-PCR. The expression levels of PTTG and bFGF mRNA in 32 cases of human pituitary adenomas were measured by RT-PCR as well. Results The expression level of PTTG mRNA in rat prolactinoma was obviously higher than that in control pituitary tissue(P

0.05).Conclusions These results suggest that the level of serum ECP can reflect the inflammation in the bronchial tube and the activated state of eosincyte more sensitively than IgE.

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.
