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 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 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.

The treatment for chylothorax depends on the underlying causes and the individual clinical cir-cumstances.It is difficult to select the best treatment measure.The main options include medium-chain tri-glyceride diet,total parenteral nutrition,drug therapy,thoracentcsis,pleurodesis,pleuroperitoneal shunting,embolization or ligation of the thoracic duct.This paper provides a brief review of the treatment for chylotho-rax.

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.

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 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.

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
