Objective To assess the quality of randomized controlled trials (RCTs) of delirium prevention of elderly published in China.Methods The literatures from China National Knowledge Infrastructure(CNKI),WANFANG Data and VIP Database for Chinese Technical Periodicals were evaluated according to Cochrane collaboration's tool for assessing risk of bias and Jadad scale.Results A total of 53 RCTs were included,14 (26.4％,14/53) described radom number table used to generate the random allocation sequence,4 (7.5％,4/53) conducted experiments in a blinded manner,7 (13.2％,7/53) did not use intentionto-treat to analyse those who did not complete the study,9 (17.0％,9/53) had high risk of other bias,none described allocation concealment mechanism and blinding to participants and intercention implementers.Based on Jadad scales,the score was 1-4,average score was (2.3±0.8),19 (35.8％,19/53) were high-quality literatures.Conclusions The quality of present published literatures is not high,the further domestic studies should be designed high-quality to better improve clinical practice.

Objective:To analyze the benefit incidence and evaluate the implementation effects on catastrophic disease insurance under the New Rural Cooperative Medical System ( NRCMS) in Jilin Province and put forward sug-gestions to perfect the catastrophic disease insurance under NRCMS. Method: In-depth interviews with related staff were conducted to gain an understanding of the operating status of catastrophic disease insurance under NRCMS;cat-astrophic disease patient data of Jilin Province from 2013 were collected, with a comparative analysis of implementa-tion effects among nine districts;the benefit incidence was analyzed by means of the Sperman rank correlation analy-sis; Results: The policy of catastrophic disease insurance under the NRCMS exhibited sound implementation effects and played an important role in reducing the economic burden of catastrophic disease patients. The average individual expenditure decreased by 4336. 52 yuan, while the reimbursement rate increased by 11. 15% after NRCMS cata-strophic disease insurance reimbursements. Additionally, statistical analysis results showed that there was a weak cor-relation between benefit incidence and economic level, the benefit equality of catastrophic disease insurance under NRCMS was relatively good, but the benefit level of rich patients was slightly higher. Conclusion:The reimbursement scheme of catastrophic disease insurance under NRCMS should be refined and improved, and the benefit fairness of different districts must be ensured, thus achieving the goal of relieving the“poverty caused by illness” phenomenon.

Objective To determine potential gene-gene interactions of TNF-? and VDR loci with outcomes of hepatitis B virus(HBV) infection.Methods A total of 391 chronic hepatitis B(HB) patients as a case group and 212 HBV self-limited infected subjects as a control group were recruited to conduct a case-control study.TNF-?-238G/A,-857C/T,-863C/A,VDR-TaqⅠT/C and FokⅠC/T gene polymorphisms were examined by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP).The interactions between TNF-? and VDR genes were analyzed by multiple model.Results There were positive gene-gene interactions between TNF-?-238 GA and FokⅠ CT/CC(ORint=4.04),between-863 CC and-857 CC(ORint=1.26) and between-857 CC and FokⅠ CT/CC(ORint=1.37),respectively,which increase the risk of chronic hepatitis B.There were negative gene-gene interactions between TNF-?-238 GA and-857 CC(ORint=0.92)and between FokⅠ CT/CC and TNF-?-863 CC(ORint=0.95),which decrease the risk of chronic hepatitis B.Conclusion Interaction between TNF-? loci and VDR loci potentially increase the risk of chronic hepatitis B after HBV infection.

Objective To measure the level of interleukin-15(IL-15) in serum and its expression in lung tissues,and analyze the correlations between IL-15 and IL-4,IFN-?,eosinophil(Eos),and explore the effect of IL-15 on bronchial asthma.Methods Thirty femal BALB/C mice were randomly divided into three group(n=10),group A(asthma model),group B(corticosteroid treatment) and group C(normal control).All mice were killed 24 h after final OVA challenge.Blood were obtained for measurement of serum IgE,IL-4,IFN-? and IL-15 levels by enzyme-linked immunoabsorbent assay(ELISA).Bronchoalveolar lavage fluid(BLAF) was collected for Eos count.The left lungs were isolated for pathological examination.The lung sections were stained with hematoxylin and eosin(HE).The expressions of IL-15 in lung tissues were measured by immunohistochemical SP method.Results ①The mouse asthma model appeared ethological changes specific to asthma,the Eos count in BALF was increased,and IgE and IL-4 levels in serum were also increased compared with control group(P

Objective: To analyze the effects of the catastrophic disease insurance of New Rural Cooperative Med-ical Scheme ( NRCMS) on alleviating the economic burden of patients in Beijing, and evaluate the effect of the policy implementation. Methods: Based on high, middle and low economic development levels and the implementation pro-ceedings of catastrophic disease insurance of NRCMS, this paper selects 3 districts of Beijing, from which it chooses two or three villages and towns with the highest numbers of catastrophic disease patients, in order to understand the opera-tional status quo of the catastrophic disease insurance through in-depth interviews with managers. This paper conducts questionnaire survey among all catastrophic disease patients from the sampled villages and towns, and uses 497 valid questionnaires received to understand patients' subjective feelings and collect relevant data of family income and medical expenditure of catastrophic disease patients in 2013. Then it carries out data docking with the platform of NRCMS man-agement centers and measure the economic burden of catastrophic disease patients. In this paper, quantitative and qualitative data are analyzed using statistical and thematic analyses, respectively. Results: The catastrophic disease in-surance of NRCMS has significantly played an important role in reducing the average medical expenditure of catastroph-ic disease patients and improving the actual compensation ratio in varying degrees. However, the incidence of cata-strophic health expenditures has not significantly improved. Conclusion: This paper suggests to increase deductibles and reimbursement ratios of catastrophic disease insurance in order to broaden reimbursement directory and other initiatives to improve the compensation level and focus on alleviating the economic burden of catastrophic disease patients.

Objective:To understand the patients'satisfaction on catastrophic medical insurance of New Rural Cooperative Medical Scheme ( NRCMS ) , and provide references for effective management and policy improvement. Methods:According to the principles of representative sampling, a questionnaire survey conducted. 484 patients got compensation for catastrophic insurance in 2013 were surveyed, and information of medical costs was analyzed. Re-sults:The average medical cost accounts for 84. 57% of total household expenditure. Mandatory medical expenditure is still high and economic burden of diseases is heavy. This policy has increased the compensation rate, and the actu-al compensation rate increases 4. 79% in three districts. The average score of patients' attitude toward catastrophic medical insurance is (3.95±1.05) points, 88. 43% of patients continue to participate in medical insurance. Con-clusions and suggestions:Patients' satisfaction on catastrophic medical insurance of NRCMS is high. It is suggested that the existing financing modes should maintain stability in the short term, and the compensatory rate should be im-proved reasonably.

Objective To translate the 3-minute diagnostic confusion assessment method(3D-CAM)into Chinese,to revise it,and to test its reliability and validity in elderly patients.Methods We translated and culturally adapted 3D-CAM into Chinese.The sample was formed by 230 elderly patients over 65 years of age.We tested inter-assessors reliability and criterion validity (diagnostic validity)and then computed the sensitivity,specificity,positive predictive value,and negative predictive value of the Chinese version of 3D-CAM.Results Correlation analyses between each item and its total score showed that the correlation coefficients ranged between 0.290 and 0.724,all reaching statistical significance(P＜0.01).Inter-assessor reliability in a sample size of 30 patients resulted in a kappa value of 0.78 (P ＜ 0.001).Compared with the gold standard,the diagnostic and statistical manual of mental disorders(DSM-5)by American Psychiatric Association(APA),the sensitivity of the Chinese version of 3D-CAM was 94.73％,the specificity was 97.92％,the positive predictive value was 90.00％,and the negative predictive value was 98.95％.Conclusions The Chinese version of 3D-CAM has achieved satisfactory reliability and validity through pilot runs in surgery and internal medicine inpatients,proved to be easy and convenient to administer,and can be used as an assessment tool for delirium in elderly surgery and internal medicine patients.

Gut microbiota plays an important role in development of diabetes with frailty. Therefore, it is of great significance to study the structural and functional characteristics of gut microbiota in Chinese with frailty. Totally 30 middle-aged and the aged participants in communities with diabetes were enrolled in this study, and their feces were collected. At the same time, we developed a metagenome analysis to explore the different of the structural and functional characteristics between diabetes with frailty and diabetes without frailty. The results showed the alpha diversity of intestinal microbiota in diabetes with frailty was lower.
