Objective To examine the relationship between CCT 5 ,γδ T cell and autoimmune diseases .Methods Recombinant CCT5 protein was cloned , expressed and purified in E.coli.Three peptides of CCT5 protein were used to prepare for anti-CCT5 monoclonal antibodies .Purified CCT5 protein was used to expand γδT cells from pe-ripheral blood mononuclear cells (PBMC).Plasma level of CCT5 in healthy donors, patients with rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE) were detected by ELISA assays .The correlation analysis between plasma CCT5 concentration and the percentage of different subtypes of γδT cells measured by flow cytometry was made . Results The CCT5 gene was amplified by PCR and the length of the target fragment was 1 750 bp.The expressed 65 ku CCT5 protein was purified and validated by SDS-PAGE.Two paired monoclonal anti-CCT5 antibodies were screened to detect CCT5 protein in plasma.Immobilized recombinant CCT5 protein was able to induce specific sig-nificant amplification of peripheral γδT cells.Correlation analysis of 10 healthy donors indicated significant corre-lation between the plasma CCT 5 concentration and the proportion of Vγ9 and Vδ2 γδ T cells.The plasma CCT5 concentration significantly decreased in autoimmune diseases patients , including RA and SLE .Conclusions These data suggest that CCT 5 could be a novel Vγ9δ2 γδT cell-related factor in autoimmune diseases , which deepen the understanding of Vγ9δ2 γδT cell function in autoimmune diseases .

Objective:To elucidate the possible role of galanin in the development of experimental depression in rats. Methods:Openfield was performed to test the behavior of rats. The changes of the galanin level in different brain areas were determined by RIA. The effect of fluoxetine hydrochloride on galanin level were observed by intraperitoneal injection. Results:Compared to control group, the crossing times and rearing times decreased significantly in depressed rats, galanin level decreased remarkably in plasma, hypothalamus, hippocampus, forebrain, parietal lobe and temporal cortex of depressed rats. Intraperitoneal injection of fluoxetine hydrochloride obviously improved the depressed behavior in rats, increased the galanin level in the hippocampus and forebrain of depressed rats. Conclusion:Hippocampus and forebrain may be involved in the development of experimental depression and in the antidepressive effects of fluoxetine hydrochloride.

Objective:To investigate the efficiency of carbon nanotube(CNT)-PAMAM mediated entrance of anti-survivin oligonucleotide into HepG2 cells,and its effects on the proliferation of HepG2 cells.Methods:CNT-PAMAM-anti-survivin oligonucleotide compounds were prepared and characterized by AFM and 1% agarose gel electrophoresis analysis.TEM was used to observe the distribution of CNT-PAMAM-ASODN compounds in HepG2 cells.CNT-PAMAM-ASODN compounds were added into the medium and co-cultured with HepG2 cells for 24 h,48 h,72 h,and 96 h at 37℃,5% CO_2.MTT method was used to detect the effects of ASODN and CNT-PAMAM-ASODN on the proliferation of HepG2 cells.Results:CNT-PAMAM-ASODN compounds were successfully synthesized via AFM and agarose gel electrophoresis.TEM showed that the compounds were located in the cytoplasm.When CNT-PAMAM-ASODN(1.0 ?mol/L)and ASODN(1.0 ?mol/L)were used for a 48 h culture,the inhibitory rates of HepG2 cells were(45.97?4.28)% for CNT-PAMAM-ASODN compounds group,(9.33?0.85)% for ASODN group,and(6.37?0.69)% for CNT-PAMAM group.CNT-PAMAM-ASODN compounds at 1.5 ?mol/L inhibited HepG2 cells by(70.22?7.25)%,and the inhibitory effects were in a time-and concentration-dependent manner.There was statistical difference between experiment group and control group(P

Objective To study the reasons of natural death of Oncomelania hupensis snails by comparing the differences of the indicator days covered with water DCW in snail marshland and non?snail marshland around the build of Three Gorges Dam in Eastern Dongting Lake areas. Methods Two marshlands were selected one was a non?snail marshland Qianliang Lake and another was a snail marshland Junshan Park . The measuring points were set through the mechanical sampling. The snails and elevation of the points were surveyed and the data of the water levels from the hydrological station were collected and then DCWs were calculated. Results From 1995 to 2013 DCWs of the marshland of natural death of snails were all more than that of the snail marshland P<0.01 . In Qianliang Lake marshland the difference between DCW before natural death and DCW from natural death until the dam was not significant P=0.23 while DCWs of the two stages both were more than that after the dam P1=0.045 P2=0.002 . Before the build of the dam DCW of the Qianliang Lake marshland of natural death of snails was more than that after the build of the dam P=0.013 and there was the same situation in Junshan Park marshland P=0.005 . The relationship between snail density and DCW was not significant in Junshan Park marshland rs=0.008 P=0.914 and the reference range of DCW of all the measuring points was 76-251 days. Conclusion In the eastern Dongting Lake district the build of Three Gorges Dam and DCW may be not the direct factors affecting the natural death of snails and the latter may change the distribution of snails.

AIM: To evaluate the prophylactic effect of aminophylline on the pulmonary hypertension rebound reaction to exposure to NO in the hypoxic pigs. METHODS: The 10 pigs undergone Swan-Ganz catheter, the mPAP was measured with a Physio-recording instrument and PaO 2 was measured with a blood gas analyzer, when breathing NO for 30 minutes and suddenly stopping breathing NO, administing aminophylline 0.25 g, followed by 30 minutes with room air. The respiratory rate and heart rate were also monitorried with a Hewlett-Packard portable monitor. RESULTS: The mPAP of the acute hypoxic pig was induced significantly after breathing 10 -5 NO. When suddenly stopping breathing NO, the induced mPAP became more and more high, the level of the mPAP in 5 minutes was similar to the values before absorbing NO, the mPAP in 10 minutes was higher than values before absorbing NO, while the level of PaO 2 was lower than the values before absorbing NO; but suddenly stopping breathing NO, administing aminophylline, although the induced mPAP became high, the speed was slower than the controls, the level of the mPAP in 30 minutes still was lower than the values before absorbing NO. CONCLUSION: Aminophylline has preventive effects on the pulmonary hypertension rebound reaction to exposure to NO in the hypoxic pigs.

OBJECTIVETo search for an effective therapy for allergic rhinitis.

METHODSOne hundred and twenty cases of allergic rhinitis were randomly divided into a treatment group (n=60) treated mainly with penetration needling, Yintang (EX-HN 3)-through-Bigen (root of nose), Sibai (ST 2)-through-Bigen, Yingxiang (LI 20)-through-Bigen, and a control group (n=60) treated with oral Biyankang, 4 tablets each time, 3 times daily. Their therapeutic effects were compared.

RESULTSThe total effective rate was 85.0% in the treatment group and 60.0% in the control group, with a very significant difference between the two groups (P<0.01).

CONCLUSIONThe penetration needling as main therapy has a definite therapeutic effect on allergic rhinitis, which is significantly better than that of oral Biyankang.

Abstract: Objective To understand the mental health literacy level of residents in Hainan Province, and to provide evidence for promoting mental health promotion and improving the mental health literacy level of residents. Methods Multi-stage random sampling method was used to investigate The National Mental Health Literacy Questionnaire among 6 895 residents in 12 districts including Changjiang, Chengmai, Dongfang, Ledong, Lingshui, Haikou Longhua District, Haikou Meilan District, Qionghai, Sanya, Tunchang, Wenchang and Wuzhishan. Results　In the survey 6 895 residents in 12 counties, cities, districts of Hainan Province, 365 of them reached the standard of mental health with the standard rate of 5.3%. The mental health knowledge score was (54.00±17.02) with the standard rate of 7.7%; the self-assessment score was (26.11±3.99) with the standard rate of 75.9%; the score of mental health skill was (26.22±7.25) with the standard rate of 44.8%. The mental health literacy level of medical workers was the highest, with the standard rate of 13.5% (112/830), and the mental health literacy level of farmers was the lowest, with the standard rate of 0.8% (13/1 647). The results of unconditional Logistic regression showed that the factors entering the regression model included educational background (OR=2.268), personal monthly income (OR=1.129), gender (OR=1.302), household registration (OR=0.776), and whether they had participated in mental health related courses OR training (OR=0.511). The higher the educational background and personal monthly income, the higher the psychological quality. The mental health of women was higher than that of men, and that of urban was higher than that of rural, and those who had participated in mental health related courses were higher than those who had not. Conclusions The mental health literacy level of Hainan residents is at a low level, and the influencing factors are multifaceted. It is suggested to strengthen the mental health monitoring comprehensively and carry out rich health education service mode for different groups.

OBJECTIVETo study the effects of peroxisome proliferator-activated receptor gamma agonists on angiotensin II-induced cellular response in cultured fibroblasts derived from patients with hypertrophic scars, so as to investigate its effects on preventing the formation of hypertrophic scars.

METHODSFibroblasts were freshly isolated from hypertrophic scars and cultured with angiotensin II, rosiglitazone and GW9662 at a certain concentration. Fibroblasts proliferation were assessed via Cell Counting Kit-8; the mRNA and protein expressions of Collagen I and Fibronectin (FN) were determined by quantitative real-time RT-PCR and Western blotting.

RESULTSThe absorbance of CCK-8 and relative expression of Collagen I, FN mRNA and protein were 1.082 5 +/- 0.007, 6.45 +/- 0.97, 4.92 +/- 0.86, 2.92 +/- 0.41, 2.78 +/- 1.04 in Ang II group; 0.722 4 +/- 0.012, 1.82 +/- 0.34, 1.78 +/- 0.27, 1.57 +/- 0.46, 1.68 +/- 0.39 in Ros + Ang II group; 0.554 7 +/- 0.012, 0.97 +/- 0.12, 1.07 +/- 1.08, 1.05 +/- 0.43, 1.14 +/- 0.36 in Ros group; 1.056 0 +/- 0.005, 5.83 +/- 0.24, 4.47 +/- 0.32, 2.69 +/- 0.35, 2.62 +/- 0.27 in GW9662 + ros + Ang II group. The results showed a significant difference between the Ang II group and the control group (P < 0.05). The effect of Ang II could be markedly inhibited by Ros (P < 0.05). In addition, Ros did not influence cell proliferation and production of extracellular matrix (P > 0.05). There was a significant difference between the GW9662 + Ros + Ang II group and the Ros + Ang II (P < 0.05).

CONCLUSIONSPPAR-gamma agonists inhibit Ang II-induced proliferation and extracellular matrix synthesis effectively in the hypertrophic scar fibroblasts. Thus PPAR-gamma agonists may have potential therapeutic effect for hypertrophic scar.
