Objective:To explore the effects of electroacupuncture(EA)on rats with chronic unpredictable mild stress(CUMS)-induced depression and proteins related to endoplasmic reticulum stress(ERS). Methods:Thirty-two Sprague-Dawley rats were randomly divided into a control group,a CUMS group,an escitalopram(ESC)group,and an EA group.Except for the control group,rats in other groups were exposed to CUMS.From the 1st day of modeling,the EA group was treated with EA at Baihui(GV20)and Yintang(GV29)every day,15 min each time;the ESC group was given intragastric intervention[ESC 10 mg/(kg·bw)every day],both for 28 d.Body mass measurement,open field test(OFT),and sucrose preference test(SPT)in each group were performed before(day 0)and after experiment(day 28)to record body mass growth,sugar preference index,and total distance and duration of central area in OFT.The protein expression levels of glucose-regulated protein 78(GRP78),caspase-12,and C/EBP homologous protein(CHOP)in the hippocampus and frontal cortex were detected by stain-free total protein normalization method of Western blotting.Meanwhile,the TdT-mediated dUTP-biotin nick end labeling assay was performed to determine the percentage of cell death in the frontal cortex. Results:After EA at Baihui(GV20)and Yintang(GV29),the body mass growth,sugar preference index,and total distance and duration of central area in OFT were effectively improved(P<0.05 or P<0.01);compared with the CUMS group,the expression levels of GRP78 and CHOP in the hippocampus,and caspase-12 and CHOP in the prefrontal cortex of rats were significantly reduced(P<0.05),and the apoptosis rate of cells in the prefrontal cortex decreased significantly(P<0.05). Conclusion:EA at Baihui(GV20)and Yintang(GV29)can significantly mitigate behavioral deficits of rats with CUMS-induced depression.The mechanism may be related to adjusting the ERS and inhibiting cell apoptosis.

Multivariate time series problems widely exist in production and life in the society. Anomaly detection has provided people with a lot of valuable information in financial, hydrological, meteorological fields, and the research areas of earthquake, video surveillance, medicine and others. In order to quickly and efficiently find exceptions in time sequence so that it can be presented in front of people in an intuitive way, we in this study combined the Riemannian manifold with statistical process control charts, based on sliding window, with a description of the covariance matrix as the time sequence, to achieve the multivariate time series of anomaly detection and its visualization. We made MA analog data flow and abnormal electrocardiogram data from MIT-BIH as experimental objects, and verified the anomaly detection method. The results showed that the method was reasonable and effective.

Objective:In order to provide policy-makers with basis and reference for improving the operational efficiency of county general public hospitals, this paper studies the changes in overall efficiency, technical efficiency and scale efficiency of 40 county general public hospitals in Fujian province from 2009 to 2014 , as well as how the to-tal factor productivity changes over the time. Methods: After collecting the relevant data of hospital operations from 2009 to 2014, this paper uses CCR, BBC, Malmquist model and other data envelopment analysis (DEA) methods to analyze the data. Results:The vast majority of those 40 county general public hospitals are in decreasing state. The total factor productivity of 40 hospitals from 2009 to 2014 is 1. 019. There are 21 hospitals (52. 5%) that slightly im-proved their productivity, of which 3 hospitals increased their productivity mainly due to technological progress, 3 hospitals due to efficiency increase, and the rest 15 hospitals due to the effect of both technological progress and effi-ciency increase. Conclusions:The operational efficiency of county general public hospitals in Fujian province is gen-erally insufficient, and there are significant differences between operating efficiency of different regions. The efficien-cy of hospitals in mountainous areas had increased, but the efficiency of hospitals in coastal areas had decreased. Therefore, in order to increase investment in county general public hospitals, the government should take differential policy and pay attention to the reasonable control of hospital size, as well as to strengthen the connotation building and attach importance to improving medical service technologies.

Objective To explore the relationships between resistin rs1477341 , rs3219175 and type2 diabetes mellitus (T2DM) in Guangdong. Methods 180 patients of diagnosed T2DM in the Second Affiliated Hospital of Guangzhou Medical University from January 2013 to December 2014 were enrolled in the study as the treatment group and another 180 subjects taking health examination as the control group. The genotype distributions of rs1477341 locus A/T, rs3219175 locus A/G were compared and the relationship between the genotypes and T2DM were anlysed by the logistic regression. Results The frequencies of the rs1477341, rs3219175 locus genotype reached the genetic equilibrium, showed their representativeness of a population group. The frequency distribution of rs1477341 genotype was statistically insignificant across the two groups (P > 0.05). The frequency of rs3219175 genotype AA+AG was decreased while genotype GG increased significantly compared to the control group (P < 0.05). The logistic regression results suggest genotype GG may increase disease risk of T2DM which the morbidity rate of AG homozygote was 0.630 times as high as that of GG homozygote (OR =0.630, 95%CI:0.405 ~ 0.980, P < 0.05) and the morbidity rate of GG homozygote was 1.551 times as higher as that of AA+AG homozygote (OR = 1.551, 95%CI:1.016 ~ 2.368, P < 0.05). Conclusions rs1477341 genotype has no correlation with T2DM among the population in Guangdong , but rs3219175 genotype does. GG may have a higher susceptibility to T2DM.

Newcastle disease virus-like particles (NDV VLPs) are composed of matrix protein (M) as the skeleton,with the insertion of hemagglutinin-neuraminidase and/or fusion protein.NDV VLPs are reported to be immunogenic and can induce specific humoral and cellular immune responses.However,its relationship with innate immunity remains elusive.Dendritic cells (DCs) are a group of specialized antigen presenting cells,which are crucial in connecting innate immunity and adaptive immunity.In this study,NDV VLPs and murine DCs were used to investigate the connection between NDV VLPs and innate immunity.The DC maturation induced by NDV VLPs (M+ HN) was evaluated.The results showed that NDV VLPs could be effectively taken up by DC and presented to naive T cells.NDV VLPs-induced DC significantly up-regulated the expression of MHC Ⅱ and costimulatory molecules on DC surface,and subsequently promoted the secretion of proinflammatory cytokines.This experiments also showed that different assembled NDV VLPs induced significant stimulating ability in cytokine levels.In summary,NDV VLPs can induce DC maturation,which gives insights to better understanding of VLPs-mediated innate immunity and provide information in selecting preferred NDV VLPs candidate.
