Objective To explore the clinical efficacy of Naikan cognitive therapy(NCT) for alcohol dependent patients.Methods 64 cases of alcohol-dependent patients were randomly assigned to the study group (32 cases) and the control group (32 cases).The study group was treated with NCT for successive 7 days on the basis of taking original drugs; and the control group was only given the original drug therapy.The obsessive compulsive drinking scale (OCDS),self-report symptom inventory(SCL-90),nurses observation scale for inpatient evaluation(NOSIE) were administered to all subjects at pre-and post-treatment.Results ①After the treatments,the scores of OCDS in study group (49.51 ± 1.63) were lower than that in control group(53.92 ± 1.82),and the statistical difference had the significance (P ＜ 0.01).②After the treatments,the total scores and some factor scores of SCL-90 in study group were lower than in control group (t =-2.413,P =0.019 ; t =-2.033,P =0.047 ; t =-2.065,P =0.044 ; t =-2.038,0.046),and the difference was statistically significant.③After the treatments,in the study group,the scores of the total estimated factor and total positive factor(187.10 ± 18.80;78.51 ±12.22) were higher than in control group (175.51 ± 11.71 ; 68.22 ± 11.87),total negative factor score (15.55 ±9.46) were lower than in control group (20.51 ± 9.33),and the difference was statistically significant.Conclusion NCT can effectively inhibit alcohol craving,and reduce the drinking wine relevant questions.It can help to improve psychological symptoms in patients with alcohol dependence,especially depression and anxious symptoms.

Objective: To evaluate the relevance of diabetes mellitus and hepatitis B virus(HBV) infection in people by Meta-analysis. Methods: Databases we searched included CNKI, VIP China Science and Technology Journal Database, Wanfang Data Knowledge Service Platform, PubMed, Cochrane Library and Web of Science Core Collection database. Publication time was from January 1997 to May 2017. The Languages were limited to Chinese and English. English search terms include: diabetes, diabetes mellitus, hepatitis B and risk. Chinese search terms include: diabetes mellitus, hepatitis B and risk. We included all observational studies on diabetes and HBV infection. Firstly, the Newcastle-Ottawa Scale and the evaluation criteria of Cross-sectional study recommended by Agency for Healthcare Research and Quality were used to evaluate the quality of articles. Secondly, RevMan 5.3 software was used for heterogeneity testing. Subgroup analysis, random effects model and Mantel-Haenszel method were used to calculate the combined OR value. Finally, Stata 14.0 software was used to conduct the sensitivity analysis, and Begg rank correlation method was used to detect the publication bias. Results: A total of 12 studies were included, comprising 6 cross-sectional studies and 6 case-control studies. But the 12 articles were heterogeneous (χ²=42.10, P<0.001). After subgroup analysis, cross-sectional studies of diabetes and HBV infection were still heterogeneous (χ²=28.21, P<0.001), whose combined odds ratio (OR) was 1.36 (95%CI: 1.03-1.80). But the heterogeneity of case-control studies was not statistically significant (χ²=10.32, P=0.070), whose combined odds ratio (OR) was 1.55 (95%CI: 1.10-2.17). After the sensitivity analysis, the 95%CI of the combined OR of the 7 studies did not fluctuate, and the lower limit was above 1.07. No publication bias was detected in the cross-sectional study subgroup (Z=1.35, P=0.176) and the case-control study subgroup (Z=1.69, P=0.091). Conclusion Patients with diabetes are more likely to be infected with HBV than those without diabetes. Diabetes mellitus is likely to be a risk factor for HBV infection.

Objective To assess whether propofol call induce stable psychic dependence in the rats by self-administration experiment. Methods Twenty-four male SD rats 14 weeks old weighing 240一270 mg were studied. Anesthesia was performed with intraperitoneal injection of 3%sodium pentoharbitsl 40 ms/kg and atropine 03 mg/kg.A catheter wag inserted into the right external jugular vein. Penicillin(100 000 U)0.2 ml wag injected through the external jugular vein for anti-infection and heparin sodium(50U/ml)0.1 ml for anticoagulation. The self-administration experiment of 14 days was started after the 7 days of recovery. All the rats were randomly divided into 4 groups(n=6 each):contontrol group(C),propofol 0.56 mg/kg/l group(P1),propofol 1.00 mg/kg group(P2)and pmpofol 1.70 ms/kg group(P3).The experimental events were controlled by a computer with 50 times of the maximum injection per day.The times ofactive and inactive nose-poke response and times of drug iniection were recorded per day.Results Compared with group C and P1,the times of active nosepoke response and injections were significantly increased in group P2 and P3(P<0.01).The times of active nosepoke response and injections per day were significantly increased in group P3 than in group P2(P(0.01).There was no significant difference in the times of active nose-poke response and injections between group C and P1.There was no significant difference in inactive nose-poke resporme between the 4 groups.And the total daily doses of propofol injected in the last 3 days were significantly increased in a dose-dependent manner.Conclusion Propefol can induce the development of psychological dependence in rata and it is related to the dosage.

Objective:This study intended to explore the current sexual and childbearing stigma, experienced by chronic hepatitis B patients in China, and to develop related preventive strategies.Methods:We used a self-made questionnaire to investigate the sexual and childbearing stigma suffered by chronic hepatitis B patients in four provinces of China. Analysis of variance and chi-square test were used to compare the differences on sexual and childbearing stigma indexes between different demographic variables.Results:We surveyed 797 chronic hepatitis B patients in four provinces. Among them, 4.15 % (28/675) of the patients were persuaded not to give birth to children, and 4.67 % (10/210) of patients were told to stop pregnancy, by their medical care takers or by members from the family planning institutions. 3.62 % (25/690) and 3.48 % (24/690) of the patients were not able to enjoy the family planning or reproductive health services as they were stigmatized,suffered, as having HBV infection. Among the male chronic hepatitis B patients, the under 30 years group suffered less sexual and childbearing stigma than those who were aged 31- ( P=0.011) or 51 and above year-olds ( P=0.009). Among female chronic hepatitis B patients, the 31- year-olds group suffered less sexual and childbearing stigma than those under 30 years group but higher than those aged 41- ( P=0.001) or 51 and above ones ( P<0.001). Patients with knowledge on route of sexual transmission for HBV, were more likely to practice less related sexual behaviors than those without such knowledge ( P=0.022). Patients who were aware or not that condoms could reduce the risk of HBV infection did not show statistically significant difference on sex behaviors ( P=0.612). Conclusions:Chronic hepatitis B patients did suffer from sexual and childbearing related stigma, with women aged 31-40 years old the most. It is necessary to advocate on the advantage of condom use for prevention of HBV transmission among pregnant women, both horizontally and vertically. Strategies on protection the rights of patients with hepatitis B should be developed and strengthened.

Combined vaccines contain two or more antigens. Research suggested that combined vaccines could prevent multi diseases and reduce the frequency of vaccination. This article focus on combined vaccines for children used both at home and abroad, such as diphtheria-pertussis-tetanus vaccine (DTaP), measles-rubella-mumps vaccine (MMR), etc. and summarizes their immunogenicity, safety and social values, including benefits to families, vaccination workers and health services, to provide evidence for promoting the research, development and use of combined vaccines in China. We found that combined vaccines can not only ensure the immunogenicity and safety, but also give convenient and lower cost vaccination to families, and using combined vaccines can improve the work efficiency of vaccination workers, reduce the impact of the epidemic on immunization services and improve vaccination coverage and timeliness. At present, the promotion of combined vaccines in China is restricted by many technical bottlenecks, high prices, and low awareness among people. It is recommended that research on the safety, effectiveness and health economics of combined vaccines should be strengthened, and the value of combined vaccines should be scientifically evaluated; the public's awareness and trust in combined vaccines should be enhanced, as well as the development and application of multi-linked multivalent vaccines should be promoted. The government should improve regulations to assist the development and application of combined vaccines.

Human challenge trial (HCT) is a test in which human volunteers are intentionally infected with pathogens in order to evaluate the efficacy of candidate preventive or therapeutic drugs. During the COVID-19 pandemic, the HCT of vaccines has aroused people's attention due to its significant advantages over clinical trial. This paper introduces the concept, development and application of HCT, the advantages and limitations of HCT for vaccine evaluation, and the consideration of future HCT of COVID-19 vaccine in China.
