Objective To provide useful information on reducing risky drinking for the Dept.of Public Health taking a county in Yunnan province as an example to explore the risk factors related to risky drinking.Methods A total of 574 participants identified as Miao,Yi and Han People at or older than 12 years old,who had been living there for 6 months or more were selected and surveyed in 5 townships in the county through stratified sampling.Alcohol consumption was collected using the beverage-specific quantity frequency (BSQF) method and analyzed using binary logistic regression and chi-square test.Results The number of drinkers in the family,undesirable drinking environment among friends and enculturation (β =0.073) could increase the likelihood of risky drinking.Risky drinking pattern was positively associated with age (β =1.006),and negatively associated with gender (β =-2.947) and awareness of risky drinking among rural residents.Conclusion The important measures to control risky drinking behavior in terms of health promotion and education include reducing the number of drinkers in the family,and preventing from undesirable drinking environment among friends and harmful drinking culture.These measures are crucial to prevent early onset of alcohol drinking among teenagers and to reduce risky drinking among middle aged and aged population.

ObjeCtive To investigate the value of protein biochip in the diagnosis of Lyme borreliosis. Methods The serum IgM and IgG antibodies against flagellin were detected by flagellin coated-and N-hydroxysuccinimide (NHS) modified-biochips in 82 patients with neuroborreliosis (NB),35 patients with erythema migrans (EM) and 44 normal controls.The results were compared with those from enzyme-linked immunosorbent assays (ELISA) and Western blot.Results The levels of both IgM and IgG antibodies were significantly higher in the NB patients than those in the normal controls (P

Objective To explore the features of transsphenoidal microsurgical treatment of male pro- lactinoma and to evaluate the sexual function before and after transsphenoidal microsurgery.Methods A se- ries of 23 cases male prolactinoma were analysed combined with retrospective and prospective study.9 casese with sexual disfunction had finished the International Index of Erectile Function with 15-item questionnnaire (ⅡEF-15) before and after the surgery.Results 8/10 cases treated with dopaminergic agonist combined with surgery achieved complete remission,while only 4/13 cases achieved complete remission with surgery on- ly(x~2=5.490,P=0.036).Aecoding toⅡEF-15,sexual function improved after surgery in 9 cases(paired- sample) t test,P＜0.05).Conclusion Transsphenoidal microsurgical treatment of prolactinoma may im- prove the male sexual functions.Dopaminergic agonist combined transsphenoidal microsurgery may achieve a better outcome.

Objective To induce mice bone marrow(BM) mono-nuclear cells into dendritic cells(DC) in vitro,and then produce function vaccine of anti-myeloma by bone marrow derived dendritic cells(BM-DC).Methods Mono-nuclear cells separated from mice bone marrow were cultured in tissue culture plastics which supplemented granulocyte-macrophage clonystimulating factor(GM-CSF),IL-4.During the 8 days,there were numerous of mature DCs outgrown,and then fused with SP 2/0 myeloma cells in logarithmic growth phase cultured with 8-azaguaine by polyethylene(PEG).The resulting purified DC/myeloma hybrids were generated by selecting with hypoxanthine-aminopterin-thymidine(HAT).The specific anti-tumor activity was examined in vitro.Results Mono-nuclear cells derived from BM cultured by supplement propriate cytokines milieu in tissue culture plastics,and then exposed to lipopolysaccharide(LPS).There were plenty of mature DCs appear as early as day 8,and exhibit dramatic veils of cytoplasm and extensive dendrites in their surfaces,high express CD11c(83.19%),major histocompatibility complex(MHC)-Ⅱ(95.25%),CD86(89.24%),their capacity to stimulate primary T cell responses in mixed leukocyte reaction(MLR) would be shown strongly.Hybrids could grow well through PEG fusion and HAT selection.These hybrids could stimulate naive T cells into cytotoxic T-lymphocyte(CTLs) directed against SP 2/0 myeloma,and exhibit strong specific killed ability.Conclusions BM-DCs is fused with tumor cells ensure the tumor associated antigens could be processed and presented effectively,and stimulate specific anti-tumor immunity so that prevent or cure this kind of tumor.So it's feasible in practice to produce anti-tumor vaccine by BM-DCs.

There are many subjects related to anesthesiology and the band between anesthesiology and clinical practicevery is close. So students can not be proficient in anesthesiology by traditional teaching methods. The use of three-dimensional case teaching method in anaesthesiology teaching is a good attemptment. three-dimensional case teaching method integrate case method, multimedia technology and clinical case. It can help medical students analyze and solve clinical problems, improvetheir academic performance and enhance their clinical basic skills.

Objective To analyze the prevalence and economic burden of diabetes in Guandu district of Kunming. Methods We used probability proportional to size (PPS) sampling method to select representative sample of 4595 residents aged 18 or over from this district. Each participant received face to face questionnaire interview and physical examination. We applied different methods to measure the direct,indirect and intangible costs of diabetes. Results In the study population, the overall prevalence of diabetes was 6.2%,and females had higher prevalence of diabetes than males (6.2%vs. 5.6%, <0.05) . The DALY/1000 population of diabetes was 3.52, among which males and females were 5.18 and 6.70, respectively. Mean unit direct costs, indirect costs and intangible costs of diabetes were 3464.49 Yuan,84.48 Yuan and 4 045.97 Yuan,respectively. The total economic burden of diabetes was 401.84 million Yuan. Intangible costs represented the largest component of economic burden of diabetes,followed by direct costs. Conclusion The huge economic burden of diabetes has become the cause for concern in Guandu district. Effective measures are needed to reduce the economic burden of diabetes.

In line with the new WHO definition for health and reference of comprehensive health assessments of elderly overseas, the paper screened and set the weight for comprehensive health assessment indicators for military officers, establishing a general health assessment model as a result 402 military officers were subject to Comprehensive Health Assessments, and the outcomes were compared with subjective assessment of experts. The results of both methods are highly coincidental. It proves Comprehensive Health Assessment as a scientific quantitative health assessment method, with promising perspectives in health management in the future.

BACKGROUND:We have designed and manufactured a novel artificial cervical vertebra and intervertebral complex (ACVC) which combines the cervical titanium cage with the artificial cervical disc, and also developed the ACVC with a hydroxyapatite biocoating (ACVC-HA). OBJECTIVE:To evaluate biomechanical properties of the joint system, and the role of HA coating in promoting osseointegration and long-term stability. METHODS:Twenty-four goats were randomly divided into three groups and underwent the anterior C2/3 and C3/4 discectomy, and C3 subtotal corpectomy, fol owed by ACVC implantation (group 1) and ACVC-HA implantation (group 2), and given no intervention (black control group), respectively. group. At 12 weeks after surgery, C1-5 samples were col ected to undergo biomechanical tests and histological staining. RESULTS AND CONCLUSION:Prior to the fatigue test, compared with the blank control group, the range of motion and neural zone of groups 1 and 2 in the directions of flexion-extension and lateral bending showed no significant differences, but the above indicators were significantly increased in the direction of rotation (P<0.05). Additional y, the stiffness in al three directions was significantly lower than that in the blank control group (P<0.05). There were no significant differences in the range of motion and neural zone in al directions between groups 1 and 2. Similar results were found after the fatigue test. The histological staining showed that both two implants had good biocompatibility and abradability, but more new bone formed on the ACVC-HA. These results suggest that ACVC can effectively reconstruct the motor function of the cervical spine after decompression. Furthermore, HA coating can markedly improve bone-implant interface to promote osseointegration.

Objective To lay the foundation for further exploration on parasitifer's defence reaction to pneumolysin through constructing ply gene-deletion strain of Streptococcus pneumoniae and researching on its virulence change. Methods A linker fragment with erm gene in middle and homologous upstream and downstream fragment of ply gene at both sides was prepared by long flanking homology-polymerase chain reaction(LFH-PCR). The linker fragment was transformed into Streptococcus pneumoniae. ply-deficient strain was then screened out from blood plate which contains erythromycin and identified by PCR. ply-deficient strain growth in vitro was observed and virulence change was observed through infecting mouse model. Results PCR results showed that ply gene was replaced completely by erm gene. The ply deficient strain was successfully constructed. The growth of single strain culture medium showed that ply genetic defect made no influence on bacterial's external growth. While in the mice nasal cavity infecting experiment, deficient strain enter into blood after 6 h from infecting which obviously slower than that did wild-type(2 h). And the number of bacteria at each point was much smaller than that of wild-type(P ＜0. 01 ). The mice peritonaeum infecting experiment showed that median lethal time of wild-type was 3 d, while that of deficient strain was 18 d(P＜0. 01). Conclusion It is a good way to completely substitute ply gene using LFH-PCR. ply deletion made no influence on baterial's growth in vitro, but it resulting in reduction of bacterial virulence in vivo.
