Objective To explore the effect of long-term chronic mild stress on depression-like behaviors and the expression of heat shock protein 70(HSP70) in rats.Methods The standard SD rats were divided into two groups as following:one group (n =6) was treated with chronic mild stress for 3 weeks,and another group (n =5) was treated with chronic mild stress for 6 weeks.Depression-like behaviors of rats was observed by sucrose consumption test and open field test before and after chronic mild stress.And Western Blot,RT-PCR and immunohistochemistry were utilized to detect the HSP70 expression in the hippocampus and frontal lobes of rats after chronic mild stress.Results The sucrose favoritism in sucrose consumption test,the scores of crossing and the time for rats' retention in the center grid of open field test in long-term group were higher than those in short term group(P＜ 0.05).HSP70 expression in the hippocampus and frontal lobes of long-term group (0.81 ± 0.08,0.85 ± 0.08)detected by Western Blot and immunohistochemistry was higher that of short-term group (0.60 ± 0.06,0.85 ±0.07).HSP70 expression in the hippocampus of long-term group (0.90 ± 0.05,1.37 ± 0.38)detected by RT-PCR was higher that of short-term group(0.78 ± 0.04,1.08 ± 0.14) (P ＜ 0.05).Conclusion After long-term chronic mild stress,the depression-like behaviors decrease,and at the same time HSP70 mRNA and protein increase.

Objective To study the self-identity and security of patients with obsessive-compulsive disorder (OCD) Methods According to the Chinese Classification of Mental Disorder,Third Edition,63 inpatients and outpatients with OCD and 61 healthy controls were recruited to investigate with self-identity scale(SIS),security questionnaire (SQ),Yale-brown obsessive compulsive scale (Y-BOCS),and self-made questionnaire.Results Compared with controls,patients had lower self-identity (50.81 ± 7.52 vs 55.10 ± 6.86,P ＜ 0.01)and security(50.09 ± 11.65 vs 58.87 ± 10.22,P ＜ 0.01)than healthy controls.Female patients had lower self-identity (48.31 ±7.68 vs 52.57 ±6.98,P＜0.05) than male patients.There were correlation between self-identity and Y-BOCS (r =-0.404,P ＜ 0.01),security and Y-BOCS (r =-0.314,P ＜ 0.05),self-identity and course of disease (r =-0.284,P ＜ 0.05),security and course of disease (r =-0.259,P ＜ 0.05) self-identity and security (r =0.698,P＜ 0.01) Conclusion OCD patients have lower self-identity and security.The self-identity and security reduce with the symptoms getting worse.Low self-identity and security maybe characteristic of OCD patients.

Objective To evaluate the chnical features and prognosis of traumatic benign paroxysmal positional vertigo (t-BPPV).Methods By retrospectively analyzing the results of clinical features and prognosis in 19 patients with t-BPPV from January 2003 to September 2006,the results were compared with 51 patients with idiopathic benign paroxysmal positional vertigo (i-BPPV).Results The mean ages were (51.3?19.1) years in t-BPPV group and (63.2?16.5) years in i-BPPV group,the difference was significant (t=2.57,P0.05).The one-stage success rates were 62.5% in t-BPPV group and 83.6% in i-BPPV group,the difference was significant (x~2=4.94,P

Objective To explore nurses'work experience of postpartum nurses returning back to work in operating room. Methods The qualitative study was conducted by face-to-face semi-structured interviewing for collection of data from 14 nurses returning to work in the room.The data were analyzed and concluded by Colaizzi phenomenology method. Result Four themes were extracted including subjective feelings of discomfort (covering fatigue,pain, and discomfort), psychological burden (covering worry, irritability,fear and guilty),problems in security at work (covering lack of continuity and distraction at work)and finally demands for team support. Conclusions The postpartum nurses working in the operation rooms feel the experience of subjective feelings of discomfort, psychological burden, problems in security at work and demands for team support. The management should help them adapted to the work after delivery by way of flexible scheduling, dynamic flexible management back to the nurses, enhancement of communication and better control of work links.

Objective To investigate the influence of angelica sinenisis injection on bone marrow histology and ultrastructure in immune-induced aplastic anemia(AA) mice.Methods Female Balb/c mice were divided into normal group,model group,therapy group and contrast group.All mice were killed by cutting neck on the 12 th day, ulnas and femur were taken out. The bone marrow histology section and ultrastructure of mice ulnas were observed. The quantities of hematopoietic cells were counted. The number of femur bone marrow mononucleate cells (MNC) were measured.Results The quantities of hematopoietic cells in model group were lower than those in normal group (P
