Objective To investigate the effect of cognitive behavior therapy combined with drug treatment of adolescent obsessive-compulsive disorder(OCD) and the effect on quality of life.Method Yale Brown Obsessive Compulsive Scale (Y-BOCS) and quality of life in children and adolescents scale (QLSCA) were used to assess the curative effect and quality of life for 123 adolescents with OCD on the psychological clinic in hospital.t test and one way-ANOVA test were used to analyze the data.Results The effective rate of drug treatment group was 64.52％ after 12 weeks and combined treatment group was 80.33％.The effective rate of drug treatment group was 77.42％ after 24 weeks and combined treatment group was 91.8％.There was significant difference between the two groups (P ＜ 0.05).Two groups before and after treatment had significant difference (P ＜ 0.01).There was significant difference between the two groups after 12 weeks (P＜ 0.01) and 24 weeks (P ＜ 0.05).After 24 weeks of treatment,two groups of patients in the overall evaluation of the quality of life and negative ernotion had significant differences (P ＜ 0.05) and in self satisfaction,peer relationship,learning ability and attitude had significant differences (P ＜ 0.01).Conclusion Combination therapy is better than simple drug treatment,and improves the quality of life better.

Objective To examine whether IFN-λ has the ability to inhibit HIV-1 infection of blood monocyte-derived macrophages and its mechanism(s). Methods Macrophages were pretreated with IFN-λ/ IFN-λ2 for 24 h before infected by HIV-1 R5 strains (Bal, Jago, and JRFL). And then the culture supernatants were detected HIV-1 reverse transcription (RT) activity and p24 protein expression by HIV-1 BT assay and ELISA. The expressions of IFN-λ receptor, CD4, CCRS, CXCR4 were evaluated by real-time PCR. Results Both IFN-λ1 and IFN-λ2, when added to macrophage cultures, inhibited HIV-1 infection and replication. This IFN-λ-mediated anti-HIV-I activity is broad, as IFN-λ could inhibit infection by both laboratory-adapted and clinical strains of HIV-1. Investigations of mechanism(s) responsible for the IFN-λ action showed that although IFN-λ had little effect on HIV-1 entry receptor CD4 and co-receptor CCR5 and CXCR4 expression, IFN-λ inhibited HIV-I infection of macrophages through connecting with IFN-λ recep-tor. Conclusion IFN-λ could inhibit HIV-I replication in macrophages. These findings indicate that IFN-λ may have a therapeutic value in the treatment of HIV-1 infection.

Objective To evalvate the efficacy of patient-controlled epidural analgesia (PCEA) combined with ganciclovir for treatment of postherpetic neuralgia in patients.Methods A total of 60 patients with PHN,aged 51-86 yr,of ASA physical status Ⅰ-Ⅲ,were randomly assigned into 2 groups (n =30 each) using a random number table:ganciclovir group (F group) and PCEA combined with ganciclovir group (FB group).In FB and F groups,ganciclovir 0.25 g was infused intravenously twice a day for 7 consecutive days.In addition,continuous PCEA was performed simultaneously in group FB and the PCEA solution contained ropivacaine 300 mg,prednisolone 20 mg and dezocine 10 mg in 250 ml of normal saline.At 1 day before treatment (T0) and 7 days,1 month,and 6 months after treatment (T1-3),pain was assessed with visual analogue scale (VAS),and the quality of life (QOL) score and pair relief rate were recorded.Results VAS and QOL scores were significantly lower at T1-3 than at T0 in the two groups.Compared with F group,VAS scores were significantly decreased,and QOL score and pain relief rate were increased at T1-3 in FB group.Conclusion PCEA combined with ganciclovir can effectively alleviate postherpetic neuralgia in the patients.

Objective To analyze the relationships between body mass index (BMI), blood pressure and the cerebral vascular function in middle-aged population that underwent health checkup. Methods Participants from health management centers of Renmin Hospital of Hubei province, the Second Hospital Affiliated to Nanhua University, Hospital of Shandong Electric Power and Chinese People's Liberation Army No. 180 Hospital aged 45 to 64 years were selected from health checkup population by cluster sampling. Levels of height, weight and blood pressure as well as the cerebral hemodynamics were checked. Subjects were grouped according to age, BMI, systolic and diastolic blood pressure. The differences and distribution of cerebrovascular function scores (CVFS) between groups were compared and described. Moreover, the risk of stroke in the population was evaluated. Results Of the 17 258 individuals who met inclusion criteria, the abnormal rate (the score below 75 points) of CVFS was 20.9 percent. The CVFS in normal, overweight and obese groups were 91.0±15.4, 83.3±21.3, 70.3±26.5 and differences in all age groups were statistically significant (P<0.01). The CVFS in systolic blood pressure<120,120-139, 140-159,≥160 mmHg (1 mmHg=0.133 kPa) groups were 93.9±12.9, 86.5±18.9, 72.1±23.5, 56.2±25.7 and differences in all age groups were statistically significant (P<0.01). CVFS in normal diastolic pressure<80, 80-89, 90-99,≥100 mmHg groups were 91.0±16.1, 85.5±20.2, 75.4±23.6, 62.7±25.0 and the differences among all age groups were statistically significant (P<0.01). Conclusions The abnormal rate of cerebrovascular function integral and high risk stroke individuals in middle-aged health checkup people was approximately 21 percent. The overweight, obese and the high level of systolic and diastolic pressure may induce the injury of cerebrovascular function and the severity will increase with the level of BMI and blood pressure.

Exosomes are vesicle-like structures generated and secreted actively by all kinds of cells.They contain proteins, nucleic acids and also lipids from the original cells, functioning in interactions between cells by shuttling cellular cargoes, and regulation of immune response in the microenvironment.Besides, they play important roles in the oncogenesis and progression of lung neoplasms.Considerable studies have demonstrated great potentials of exosomal proteins and microRNAs as biomarkers for diagnosis, prognosis prediction and treatment of lung cancers, including immunotherapy and targeted delivering of anti-tumor drugs based on exosomes.

Objective To explore the dynamic changes in the plasma levels of thrombomodulin(TM)with traumatic hemor-rhagic shock (THS).Methods The model of the THS with gradient decerease in the systolic blood pressure was eatablished in 1 7 rats without specific pathogen.The arterial blood during the different phase of shock,i.e.when the systolic pressures were three forth,one second,two fifth of the basis systolic blood pressure,one fifth of the basic systolic blood pressure and 10mmHg,was collected and TM levels in the plasma were determined by the double antibody sandwich method of enzyme-labeled immunosorbent assay (ELISA)and analyzed.Results There were significant differences in plasma levels of TM be-tween groups,with TM levels in T2~T3 period of time increased with the extension of time,and TM levels in T4~T5 peri-od of time decreased with the extension of time,and TM levels in T5~T6 period of time increased with the extension of time.Conclusion The animal model of THS was related to the systolic pressure during the shock,may be helpful to assess-ment changes in blood loss.The dynamic observation of the plasma levels of TM which is a good index of the damage to the vascular endothelial cells,may be helpful to assessment of the THS is related to the degree of damage to the vascular endo-thelial cells.
