ObjectiveTo analyze the surveillance results at the national surveillance spots of brucellosis from 2006 to 2010,to know the epidemic status of national brucellosis,and to provide scientific evidences for evaluating of surveillance quality and formulating of surveillance strategies and measures.Methods The brucellosis surveillance data collected from the Surveillance Reports of Major Infectious Diseases and Vector-Biological Monitoring Report in China from 2006 to 2010,and the National Diseases Surveillance Information Management System were classified and analyzed using two stage clustering statistical analysis.Results According to national routine surveillance,the incidence of brucellosis increased from 1.55 per 100 000 in 2006 to 2.62 per 100 000 in 2010.Reported brucellosis cases were mainly in Inner Mongolia,Shanxi,Heilongjiang and other regions,and reported time was from March to August,which accounting for 79.87％(114 265/143 064).The brucellosis cases were mainly youth,male,farmers and herdsman.In the national surveillance spots of the brucellosis,217 648 cases received epidemic survey,of which 61 905 cases received serological test,the positive rate was 19.66％(12 169/61 905),and 10 318 new cases were found; the highest positive rate of serological test was 41.19％(2757/6694) which was found in Zhalantun of Inner Mongolia; the detection rate of pathogen culture was 2.49％(29/1165); the positive rates of serological test in cattle and sheep were 1.07％(2355/219 352) and 0.93％ (2766/296 176),respectively.The surveillance spots were classified into four grades according to cluster analysis.Conclusions The epidemic continues to rise in human surveillance spots of brucellosis.Although national surveillance spots play an important role in the surveillance of brucellosis,the quality and quantity of surveillance work of national brucellosis surveillance spots should be improved,different management measures should be taken in different surveillance spots according to classified results of the cluster analysis.This study provides some basis to improve the utilization of health resources and the level of Brucella disease prevention and control work.

This study aims to investigate the genetic characteristics of hemagglutinin in wild-type measles viruses in Henan Province, China and to provide a basis for measles control and elimination. Specimens were collected from suspected measles cases in Henan during 2008-2012. Cell culture was performed for virus isolation, and RT-PCR was used to amplify hemagglutinin gene. The PCR products were sequenced and analyzed, including construction of phylogenetic tree and analysis of the distance between the isolated virus and the reference virus; then, the variations in predicted amino acids were analyzed. The results showed that 12 measles viruses were isolated in Henan Province and identified as H1a genotype; the nucleotide and amino acid homologies were 98.0%-100% and 97.2%-99.8%, respectively. One glycosylation site changed in all the 12 sequences because of the amino acid mutation from serine to asparagine at the 240th site, as compared with Edmonston-wt. USA/54/A. Overall, the wild-type measles virus genotype circulating in Henan Province from 2008 to 2012 was H1a, with high homology between strains; there were some variations in amino acid sequences, resulting in glycosylation site deletion.

Objective: To observe the effect of electroacupuncture (EA) at Huantiao (GB 30) and Weizhong (BL 40) on thigmesthesia, gait function, and expression levels of serum immunoglobulin G (IgG) and immunoglobulin M (IgM) in rabbits with lumbar intervertebral disc herniation (LIDH). Methods: Forty healthy New Zealand rabbits were randomly divided into a blank control group, a model group, an EA at acupoint group and an EA at non-acupoint group, with 10 rabbits in each group. The LIDH pathological model of rabbit was established using the self-made LIDH model maker. The thigmesthesia and gait function of rabbits were recorded by Siegal method. The serum IgG and IgM expression levels were detected by enzyme-linked immunosorbent assay. Results: EA at Huantiao (GB 30) and Weizhong (BL 40) could improve the clinical symptoms of thigmesthesia and gait function, and inhibit the expressions of serum IgG and IgM in the LIDH rabbits, which were significantly different compared with those in the model group and EA at non-acupoint group. Conclusion: EA at Huantiao (GB 30) and Weizhong (BL 40) can improve the clinical symptoms of LIDH rabbits, which is associated with inhibition of the serum IgG and IgM expressions and reduction of the immunoinflammatory factor release. This may be one of the mechanisms of EA at Huantiao (GB 30) and Weizhong (BL 40) in the treatment of LIDH.

Objective: To investigate the effects of preoperative sarcopenia on postoperative clinical outcome in patients with gastric cancer. Methods: A prospective study was performed in 93 patients with gastric cancer and the skeletal muscle mass was examined by bioelectrical impedance. The primary outcome was postoperative complications. The secondary outcomes were postoperative length of stay, overall hospital costs, 60 days re-admission and mortality rate. Results: A significant difference (sarcopenia group vs. non-sarcopenia group) was observed in the rates of overall postoperative complications, incidence of pleural effusion and intra-abdominal infection, overall hospital stay and postoperative hospital stay (P ＜ 0. 05). The rates of 60 days readmission, 60 days mortality and hospital costs in sarcopenia group were not different between the two groups (P ＞ 0. 05). By univariate and multivariate analysis, preoperative sarcopenia and preoperative nutritional risk are the risk factors of postoperative complications. Conclusion: Sarcopenia is an independent risk factor for postoperative complications in patients with gastric cancer; preoperative patients with sarcopenia have a worse prognosis and should be screened and optimized before surgery.
