Objective: To establish an evaluation index system for health education of hand,foot and mouth disease（HFMD）in nursery children by Delphi method. Methods: After referring to the relevant literature,an initial health education index system for HFMD of nursery children was established,including four first-level indicators,twelve second-level indicators and forty-six third-level indicators. Two rounds of expert consultation were conducted according to Delphi method. The enthusiasm of experts was evaluated by response rate,and the authority of experts was evaluated by authority and variation coefficient. The consultation questionnaire in the second round was based on the results of the first round and was scored again in the same way. Then the evaluation index system of HFMD health education for nursery children was finally determined. Results: Thirteen experts participated in two rounds of consultation,including four aged 40-49 years and nine aged 50-59 years;two of deputy senior title and eleven of senior title;one worked in the health administration department,six in the CDC,five in health education institutions and one in kindergarten. The two rounds of expert consultation were carried out effectively within the time set and the response rate reached 100%. In the first round,the judgment coefficient,familiarity coefficient and authority coefficient were 0.92±0.06,0.85±0.12 and 0.88±0.06,respectively. One first-level indicator,two second-level indicators and twelve third-level indicators were added,seven third-level indicators were deleted,and the contents of one second-level indicator and ten third-level indicators were improved in the first round. In the second round,the judgment coefficient,familiarity coefficient and authority coefficient were 0.95±0.07,0.88±0.10 and 0.91±0.06,respectively. The coordination coefficients of the first-,second- and third-level indicators in the second round were 0.170,0.166 and 0.283,respectively,and the coefficients of variation were all less than 0.25. After two rounds of discussion,five first-level indicators,fourteen second-level indicators and fifty-two third-level indicators were finally established as the evaluation index system of HFMD health education for nursery children. Conclusion The evaluation index system of HFMD health education for nursery children established by Delphi method has high authority and practicability,and it can be used to comprehensively evaluate the effects of HFMD health education on nursery children.

Objective: To understand knowledge and awareness of hand-foot-mouth disease (HFMD) and associated factors among parents of kindergarten children in urban district of Huzhou City and to provide a veference for making effective measure of health education of HFMD. Methods: Self-designed questionnaire was used to investigate 851 parents from 6 kindergartens by stratified cluster random sampling. Results: The overall recognition of HFMD was 8.15±3.43, and the qualified rate was 5.17%. Awareness rates of sources, transmission routes, symptoms and signs, as well as preventive measures were 34.08%, 20.80%, 3.41% and 30.32%, respectively. Multiple linear regression analysis showed that kindergarten type(B=-1.07), gender(B=0.70), age(B=-0.41), education level(B=1.60), occupation (B=-1.37) associated with awareness of HFMD (P<0.05).The top three sources of HFMD prevention and treatment were mobile messages(45.24%), kindergarten lectures (43.24%) and brochure/propaganda column(40.19%) . Conclusion The general knowledge and awareness of HFMD among parents of kindergartens children’s parents is low in urban district of Huzhou city. In order to improve the awareness and health-related behaviors among parents of kindergarten children to prevent HFMD, child care institutions and basic public health service health education programs should be relied on, to carry out appropriate health communication and intervention.

This study was aimed to explore the molecular mechanism of nano-realgar in treatment of systematic lupus erythematosus (SLE) lupus nephritis (LN). Intragastric administration of equal volume of high-, middle-, low-dose nano-realgar suspension, and normal saline (NS) were given to MRL/lpr mice, respectively. The observations were made on levels of ANA, ds-DNA antibody, IgG and IgM in blood serum, as well as TWEAK, NF-κB, MCP-1 mRNA and protein expression levels in renal tissues. The results showed that compared with the NS group, levels of ANA, ds-DNA antibody, IgG and IgM were obviously reduced (P < 0.05); the levels of TWEAK, NF-κB and MCP-1 mRNA were obviously reduced (P < 0.05); the protein expression levels of TWEAK, NF-κB and MCP-1 mRNA were obviously reduced (P < 0.05) in the high-, middle-, low-dose nano-realgar group. It was concluded that nano-realgar intervened the TWEAK-NF-κB signal pathway through downregulating MCP-1 expression among MRL/lpr mice, in order to reduce the levels of ANA, ds-DNA antibody, IgG and IgM for relieving autoimmune damages in the treatment of SLE (LN).

Objective To study the awareness of perimenopausal hormone replacement therapy (HRT) among a part of the medical care personnel in Guiyang . Methods A survey was conducted among 500 medical staff members in 4 hospitals of Guiyang by cluster random sampling using questionnaire about HRT. Results The survey showed that 74.6% (373/500) medical staff thought that the hormone replacement therapy was necessary to perimenopausal women; 96.7% (87/90) of obstetrics and gynecology doctors believed that it was necessary for perimenopausal women to use HRT,which was significantly higher than the doctors of other specialties 68.6% (166/242) and the nurses group 71.4% (120/168) (χ2=28.509, 23.537, P<0.01). Only 5.8%(29/500) of the medical personnel were willing to recommend HRT. In light of the attitude for recommending HRT, the obstetricians and gynecologists group was more significantly higher than the other specialties doctors group (χ2=86.781, P<0.01). Conclusion The knowledge of hormone replacement therapy in part of Guiyang medical personnel is not sufficient;the recommending rate of HRT was low;the side effects of HRT was still a concern. There are differences between obstetrics and gynecology doctors and doctors other specialties and nurses in HRT knowledge.

Objective: To investigate hand hygiene of children in kindergartens in Huzhou City, so as to provide basis for improving hand hygiene and conduct health education on hand hygiene related diseases. Methods: A total of 343 children in 6 kindergartens in two districts of Huzhou City were observed by stratified cluster random sampling and observation. Results: A total of 1 042 hand hygiene indications and 886 hand washing (85.03%). The overall hand-washing qualification rate was 53.35%. Within different kindergartens, children in the lowest level kindergartens had poor hand washing habits. There was a positive correlation between levels of kindergarten and children’s hand washing habits. Boys’ hand washing habits were relatively poor, 45.35 percent of boys’ had substandard hand washing habits, which was only 19.88 percent of girl. The hand hygiene behavior of children in primary class was better than that of middle class. The proportion of substandard hand washing of children in primary class and middle class was 23.13% and 39.80% respectively. Conclusion There is a big promotion space of hand hygiene habits of children in kindergartens, so it is necessary to strengthen compliance with hand hygiene and cultivate correct hand hygiene habits.

OBJECTIVETo examine the expression of membrane-type-1 matrix metalloproteinase (MT1-MMP) and reversion-inducing cysteine-rich protein with Kazal motifs (RECK) in gastric carcinoma, and investigate its clinical significance, at the same time analyze the correlation between MT1-MMP and RECK expression.

METHODSMT1-MMP and RECK expression in surgically resected tissue samples of gastric carcinoma was examined by immunohistochemical method (two-step method) , and its correlation with clinicopathological factors was analyzed.

RESULTSAmong the 44 gastric carcinoma samples, 37 (84.1%) were stained positive for MT1-MMP, and 31 (70.5%) for RECK. The expression of MT1-MMP was much higher in poorly differentiated gastric carcinoma samples than moderately and well-differentiated samples (P = 0.015). The expression level of MT1-MMP was associated with invasive depth of tumor cells (P = 0.007), but no difference between sex and lymph node metastasis. On the contrary, the well-differentiated samples showed higher expression of RECK than poorly and moderately differentiated gastric carcinoma samples (P = 0.006). The expression level of RECK did not correlate with sex, lymph node metastasis and invasive depth of tumor cells. RECK expression showed no relation to MT1-MMP expression in the gastric carcinoma.

CONCLUSIONOverexpression of MT1-MMP in gastric carcinoma may play an important role during tumor differentiation and metastasis, the RECK protein may have positive effects on the tumor differentiation.

OBJECTIVETo explore the effect of a non-lethal heat shock, in comparison with the treatment of interferon-gamma (IFN gamma), on the expression of major histocompatibility complex transactivator (CTA) and its downstream target gene of the human leukocyte antigens (HLA)-DR in Jurkat cells.

METHODSThe changes of CTA mRNA in Jurkat cells before and after the treatment of heat shock or IFN gamma were detected using real time RT-PCR. The changes of CTA protein were detected with Western blot. The expression of HLA-DR was detected with flow cytometry. : CTA mRNA and protein were induced in Jurkat cells under heat shock, but not with IFN-gamma. The expression of HLA-DR gene significantly increased after recovery (P<0.01).

CONCLUSIONThe expressions of CTA and HLA-DR in Jurkat cells remarkably increase after heat shock, indicating that heat shock may help reconstruct relevant genes in cells with immunologic gene deficiencies.

OBJECTIVETo study the risk factors regarding heredity and environment in familial incident type 2 diabetes mellitus (DM).

METHODSTo compare the difference of environmental risk factors between type 2 DM, impaired glucose tolerance (IGT) and normal persons through study on familial information and environmental risk factors in 125 familial incident type 2 DM in-patients and out-patients from 1999 to 2001. Falconer was used to estimate heritability. Penrose was used to study the heredity damagers by polygene analysis.

RESULTSThere was a significant constituent ratio diversity (P < 0.01) in triglyceride, body mass index, waist to hip ratio, hypertension history and physical activities history among 3 groups, while no significant diversity in blood lipids and history of coronary heart disease. 83.42% +/- 5.84% heritability of type 2 DM in 125 familial predigree indicated that dominant major gene might exist in these familiar pedigrees. Analysis of polygene in these groups showed type 2 DM might conform to the model of polygene heredity.

CONCLUSIONThis study suggested that type 2 DM had significant heritability and genetic heterogeneity, which generally appeared to be a disease of multi-factorial inheritance. Environmental risk factors, genetic factors and their interactions were due to type 2 DM.
