Objective To explore the effect of psychological intervention on knee osteoarthritis patients. Methods A total of 92 OA patients were included into a one-month randomized controlled followup study, 47 of them were treated with combined psychological intervention, the other 45 cases were routinely treated. All cases were investigated on their demographic information , physiological parameters and score of the short form-36 health survey questionnaires (SF-36), self-rating depression scale (SDS) and self-rating anxiety scale (SAS). Statistics method used t-test and variance analysis. Results There was no signi-ficant difference in terms of the physiologic parameters changes between before and after treatment (P＞0.05) of the two groups. ① The SDS scores of the two groups decreased gradually after the treatment (P＜0.05),while there was remarkable descending of SDS score in patients of psychological intervention group (P＜0.05). ② The SAS scores of the two groups decreased gradually after the treatment (P＜0.05). And there was no significant difference between the two groups (P＞0.05). Compared with the non-intervention group, the fourfactors scores including physical function, pain, vitality and role limitations due to emotional problems of the intervention group were significantly improved (P＜0.05). Anegative correlation was observed between SDS and PF, BP, GH, VT and SF (r=-0.739-0521,P＜0.05). SAS was correlated negatively with VT and SF (r=-0.699～-0.475,P＜0.05). Conclusion Psychological intervention could ameliorate the depression of knee osteoarthritis patients. The quality of life of knee osteoarthritis patients can be improved by psychological intervention.

Objective To investigate the effects of exogenous transforming growth factor-β3 (TGF-β3) on the expression of endogenous TGF-β3 and proliferation of rat hepatic stellate cells (HSC).MethodsRat HSC cells were seeded in 24-well plates and were divided into 2 groups.One group of cells were exposed to TGF-β3 of different concentrations (0.08,0.4,2,10 and 50 ng/ml) for 2 hours and then the cell culture supernatant was collected; the other group of cells were exposed to 10 ng/ml TGF-β3 and the cell culture supernatant was collected at different time point (0.25,0.5,1,2,4,8 and 13 h).The content TGF-β3 was determined by ELISA method.Some other HSC cells were seeded in 96-well plates and divided into 2 groups.One group of cells were cultured in the presence of exogenous TGF-β3 of different concentrations (0.001,0.005,0.02,0.08,0.32,1.25,5,20,100,500 ng/ml) for 24 hours and then the cell proliferation was detected; the other group of cells were treated with 5 ng/ml TGF-β3 for 24 and 48 hours.The cell proliferation was measured by MTT method.The HSC cell morphology of control group and TGF-β3 treated group was observed under inverted microscope. Results The endogenous TGF-β3 expression of HSC cells obviously increased after exogenous TGF β3 treated at 2 ng/ml and reached the peak at 3 hour [(0.845±0.028) ng/ml vs (0.026±0.021) ng/ml,F=210.168,P=0.00].Low concentrations of exogenous TGF-β3 did not affect the proliferation of HSC cells.Above 0.32 ng/ml,exogenous TGF-β3 could promote HSC proliferation.There was no dose-dependent relationship between HSC cell proliferation and the concentration of exogenous TGF-β3 (F=0.68,P=0.57).Under microscope,lhere was no significant difference in HSC cell morphology between control group and TGF-β3 treated group.Conclusions Exogenous TGF-β3 can promote the expression of endogenous TGF-β3 in HSC cells,and can promote HSC cell proliferation.There is no obvious effect of exogenous TGF-β3 on HSC morphology.

Objective To assess the leading causes of death and disability adjusted life year (DALY) due to non-communicable disease (NCD) in China.Methods World Health Report 2004 published by the World Health Organization (WHO) was reviewed,including total deaths,deaths per 100 000,agestandardized death rate per 100 000,total DALYs,DALYs per 100 000 and age-standardized DALYs per 100 000 by cause and by member state.Diseases or injuries were assigned to three levels:communicable diseases,NCD and injuries (the first level); categories of disease or injure (the second level); specific diseases (the third level).R2.15 was used for data analysis.Results NCD causes 737.6 million deaths,141million total DALY years,627 age standardized mortality per 100 000,and 10 829 age-standardized DALYs per 100 000.NCD account for 79.4％ and 70.3％ total death or all-cause DALYs.Conclusions Cardiovascular disease,malignant neoplasm and respiratory disease were the leading causes of death,while neuropsychiatric disorder,cardiovascular disease and sense organ disease were the most important causes of DALYs.Among China,the United Kingdom,the United States,Canada,Japan,Korea and India,China ranked second in age-standardized mortality rate of chronic disease.DALYs of esophagus cancer and chronic obstructive pulmonary disease were 6 or 2 times of world average level.Besides,the increasing trend in the prevalence of diabetes mellitus remains impressive.

Objective To explore the sensitivity regulatory mechanism of ziprasidone capsules on prolactin( PRL) and fast insulin( FINS) in male adolescents with episode schizophrenia.Methods According to inclusion and exclusion criteria, 52 adolescent males selected from January 2015 to March 2016 were confirmed the psychiatric treatment of schizophrenia in our hospital, their ages, ziprasidone capsule usage and suffering schizophrenia stage of disease, height, waist circumference, body weight, hip circumference, and in the morning fasting blood glucose, FINS and PRL content were recorded.Mathematical model were used to calculate QUICKIFINS sensitivity index, and in accordance with the classification criteria BMI, 52 male adolescents with schizophrenia were divided into normal group and overweight group.The correlation detection, and anthropometric parameters, PRL and FINS sensitivity parameters were analysed.Results PRL and FINS, QUICKI indicators were not correlated(r=0.153, P >0.05; r=-0.101, P >0.05) statistically significant; ziprasidone capsule dose has a positive correlation with FINS(r =0.376,P <0.05), and QUICKI negative indicators (r=-0.362,P<0.05); waist-hip ratio or fat content ratio has no correlation with FINS, QUICKI indicators, but BMI and FINS has a positive correlation (r=0.389,P<0.05) and QUICKI indicators with negative correlation(r=-0.413,P<0.05);PRL level between normal group and overweight group was not statistically significant, and levels of FINS in overweight group(10.89 ±8.23) mU/L was higher than the normal group(5.79 ±3.18) mU/L, the difference was statistically significant(P <0.05).QUICKI index between the two groups was statistically significant, and the overweight of FINS was sensitivity less than the normal group.Conclusion Ziprasidone capsule has no relationship with PRL and FINS resistance in the treatment of adolescent patients with schizophrenia, while body mass index correlated with FINS resistance, and ziprasidone capsule dose correlated with FINS resistance.

The objective of this study was to assess the clinical evidence for or against mood stabilizers as a treatment for Alzheimer's disease (AD). We searched 5 databases from their inception to January 2010. Five randomized clinical trials of mood stabilizers to treat human patients suffering from AD were included. These trials assessed the effectiveness of mood stabilizers as an adjunct treatment to conventional anti-dementia drugs on behavioral and psychological symptoms, especially on agitation. Methodological quality was assessed using the Jadad score. The results suggested a significant effect in favor of placebo on the Mini-Mental Status Examination [n=270, weight mean difference (WMD), -0.89; 95% confidence intervals (CIs) -1.69 to -0.09, P=0.03] and on the Neuropsychiatric Inventory total (NPI total) (n=51, WMD, 3.71; 95% CIs 0.15 to 7.26, P=0.04). There were no significant differences in change scores on total Brief Psychiatric Rating Scale (BPRS total), NPI/BPRS agitation, Cohen-Mansfield Agitation Inventory total and Physical Self Maintenance Scale between mood stabilizers and placebo. Only one of these studies was free of methodological limitations (Jadad score=5). In conclusion, based on the existing evidence, mood stabilizers are ineffective or even harmful as a treatment for AD.

Objective To evaluate the influence of duration of laser irradiation on histomorphometric meas- urements in experimentally tenotomized and repaired rabbit Achilles tendons and to explore the best irradiation time. Methods A total of 20 male New Zealand rabbits aged 10-12 weeks were used and randomly divided into 4 groups:a control group and three experimental groups.All the animals underwent surgical excised and then repair of their Achillis tendon.The animals in the control group were then treated with sham laser irradiation,while those in the three experimental groups were treated with 10,20 and 30 minutes of He-Ne laser irradiation(632.8 nm, 18.9 mW)daily,respectively,for 14 days.On the 28th day after surgical operation,the animals were sacrificed and their Achilles tendons were sampled.HE stain and Van Geison stain were used to observe morphometric changes of tendons.The SDS-PAGE electrophoresis method and CS-930 photodensity scan instrument were employed to measure the content of typesⅠandⅢcollagen.Results it was shown that laser irradiation enhanced cell proliferation,cel- lular content,granulation tissue formation and collagen deposition in laser-treated tendons,especially in those irradia- ted for 20 minute daily,as compared to the control group.TypeⅠand typeⅢcollagen levels were significantly in- creased at the 28th day in the healing tendons and the ratio of collagenⅢtoⅠincreased in all the 3 experimental groups,and the increase of both collagen content and ratio of collagen typeⅢtoⅠwas significantly greater in those ir- radiated 20 minutes daily(P

Objective To show the international protocols for blood pressure monitoring based on a real example. Methods The assessment process of international protocol that can be released by Working Group on Blood Pressure Monitoring of European Society of Hypertension was evaluated. Results 33 participants were selected, which all indexes in evaluation stage one and stage two of the indicators were detected through. The 95% consistency interval in difference between tested device and reference monitor was 10.65～-12.67 mmHg for systolic BP and 13.68～-14.03 mmHg for diastolic BP, and there were 7.1% (7/99) and 6.1% (6/99) of valid points out of the 95% consistency interval. Conclusion The measured automatic blood pressure in the normal environment, measuring accuracy and the standard with the control of mercury -type sphygmomanometer is coincident, so it can be recommended for home application.
