Objective To evaluate the publicity and education effects of the film The Prevention of shown at the construction sites.Methods The construction workers at the showing spots were surveyed with questionnaires.The collected data was analyzed to compare the awareness rate changes of knowledge understood by workers before and after the film showing.Results The knowledge awareness rate among the construction workers increased significantly after they saw the educational film at construction sites in Wuhan City.The right answer rate of the question Whether can be prevented or increased from 82.4% to 96.8%.The right answer rate of Mother-to-child transmission of AIDS increased from 79.9% to 95.2%;and the right answer rate of Whether or not the infection of can be attributed to mosquito and insect bites increased from 38.6% to 58.4%.Conclusion It was proven effective to propagandize knowledge to the construction workers by showing educational film at construction sites.

Objective To analyze the effect of health belief to HIV/AIDS and preventive behaviors among the rural construction workers in Wuhan City. Methods The data were collected by using questionnaires at the construction sites of Wuhan City, and the relationship between health belief and preventive behaviors was analyzed and discussed. Results The HIV/AIDS health belief was at a lower level, the synthesize score was 5.6. The score of attitude was relatively high, while the score of perceived seriousness was relatively low. The percentage of the people who have commercial sexual behaviors was 7.4%. There were positive correlations between the commercial sexual behaviors and perceived seriousness, perceived barriers and attitude. The subjects who always use condoms when having sexual intercourse with their partners were accounted for 4.2%. Condom usage and cognitive-behavioral disorders was positively related.

The main purpose of this paper is to discuss the rationality and effectiveness of the application of Grounded Theory in health education. Analyzing the connotation and characteristics of Grounded Theory, the possibility of data analysis and theory construction was discussed by using Grounded Theory in the field of health education. Aiming to analyze the interview data of the health education and health promotion project, three-rank-coding method of Grounded Theory is tentatively used. Furthermore, the prospects of applied Grounded Theory in health education were also predicted in this paper.

Objective To explore the availability of HIV/AIDS prevention services in Hispanic immigrants in recent years and the influencing factors.Methods The method of systematic review was used to analyze the researches on AIDS prevention among Hispanic immigrants.Results HIV/AIDS prevention services include behavioral intervention,the environment intervention,training programs.Hispanic PLWHA were provided support services such as HARRT,AIDS drugs assistance,mental health,drug treatment monitoring,treatment of opportunistic infections.The main factors impacting the use of these services were drug abuse,psychology problems,language obstacles and suffering from discrimination.Conclusion The health care services of AIDS prevention for Hispanic immigrants are rich,but the availability is influenced by many factors.

OBJECTIVE:To study the effects of melatonin (MT) on nerve cell apoptosis and the expression of bcl-2 and cytochrome C genes in rat cerebrum with deltamethrin induction.METHODS:35 male Wistar rats were randomly divided into five groups (eight rats per group): olive oil control, deltamethrin-treated (12.5 mg/kg), deltamethrin plus melatonin (25.0 mg/kg, 50 mg/kg and 100 mg/kg respectively) group. Animal models were established by intraperitoneal injection deltamethrin in rats. Nerve cell apoptosis and the protein expression of bcl-2 and cytochrome C genes were detected by flow cytometry with PI staining and immunohistochemistry respectively.RESULTS:Compared with DM group (20.73 +/- 3.34), the positive expression gradation of the bcl-2 protein in nerve cell was increased significantly in MT groups (DM + MT(25) was 45.26 +/- 3.84, DM + MT(50) 39.4 +/- 4.04 and DM + MT(100) 34.4 +/- 4.52) (P < 0.05) but significantly lower than the control group (59.33 +/- 4.03). Compared with DM group (34.86 +/- 4.15), the cytochrome C protein in nerve cell was decreased significantly in MT groups (20.53 +/- 3.17, 28.73 +/- 2.61 and 28.66 +/- 4.82 respectively) (P < 0.05). Compared with DM group (23.06 +/- 3.63), the apoptotic rate in nerve cell was decreased significantly in MT groups [(15.0 +/- 1.77)%, (14.88 +/- 1.84)% and (11.75 +/- 1.93)% respectively] (P < 0.05).CONCLUSION:MT can protect nerve cell against deltamethrin induced brain injury by inhibiting nerve cell apoptosis, downregulate the protein expression of cytochrome C gene and upregulate the protein expression of bcl-2 gene.

目的:以1993～2004年武汉市儿童医院颅脑损伤患者为研究对象,探讨颅脑损伤儿童的性别、年龄、损伤原因和预后等特征。方法:采用描述性分析方法分析颅脑损伤儿童的性别、年龄特征以及损伤原因与转归,并对颅脑损伤患者与其他损伤患者的入院情况、住院天数、住院费用和出院转归进行比较。结果:患者男孩多于女孩,男女比例为1.86:1,年龄分布主要集中在4岁以下,前3位损伤原因是跌落(67.1%)、车祸(17.6%)和挤压/撞击(10.6%);颅脑损伤患者与其他伤害患者相比预后较差,住院死亡率较高,平均住院费用较高。结论:儿童颅脑损伤的发生有一定的规律性,预后较差,给家庭和社会造成了一定的负担,可根据其损伤原因和规律制定相应的防范措施。

Objective To introduce the principles of spectral analysis methods and explore the application of spectral analysis methods for the analysis of hospital patients′ hospitalized time. Methods Spectral analysis of the principles and methods of calculation steps was introduced, and children hospitalized with injuries were selected. By spectral analysis methods patients hospitalized time series data were analysed. Results Hospital time series in the context of frequency domain analysis, the number of people hospitalized children hurt in a time of six months for the cycle fluctuations. Conclusion Using spectral analysis, information cycle was accurately extracted. It was very important for the further processing of time series data.
