ABSTRACT
Objective To evaluate the reliability and validity of SF-36 in patients with advanced schistosomiasis,so as to proride scientific basis for the selection of suitable tools for health measure.Methods A Chinese version of SF-36 scale was applied to evaluate the health of patients with advanced schistosomiasis by a household survey in Hanshou County of Hunan Province and Jiangling County of Hubei Province,then the reliability and validity of the scale were tested.Results Atotal of 326 patients were investigated in the two counties.The split-half reliability(with a split-half coefficient of 0.95) and the internal consistency (Cronbach'α coefficients of the eight dimensions ranged from 0.86 to 0.88)were satisfying;the convergent and discriminative validity were high with the test successful rates of 97.14%and 87.86%,respectively;the criterion validity was acceptable with a correlation coefficient between the total score of SF-36 and EQ-5D+C VAS score of 0.70.However,the construct validity seemed to be not so reasonable as only 2 dimensions out of 8 were completely in accordance with the theoretical model on factor loading.The percentages of floor effect and ceiling effect in most dimensions were not significant except RP and RE(with the percentages of floor effect of 50.31%and 48.16%,respectively).Conclusions SF-36 is appropriate to be used in patients with advanced schistosomiasis.but some items need to be improved according to the local settings of endemic areas.
ABSTRACT
AIM: The auxology-related indexes are important for tissue construction. In this article, we investigated the incidence of overweight and obesity and their effects on physical functions and qualities of Guangzhou adults in 2005. METHODS: 2 056 adults including 1 027 males and 1 029 females were randomly selected from Guangzhou in 2005 for physical examination. The anthropometric data such as body mass and height were collected to calculate body mass index (BMI). The subjects were divided according to the BMI criteria recommend by Group of China Obesity Task Force, and their physical functions and qualities were analyzed. RESULTS: In 2005, the detection rate of overweight and obesity in adult males were 28.7% and 5.2%, and in females were 18.6% and 5.3%. The values of diastole pressure and systolic pressure were increased with BMI, but the change tendency of step index and vital capacity/body mass was decreased with BMI. The rate of hypertension was increased with BMI, and male subjects had higher rate of hypertension than that of female subjects in all groups. Obese adult had the poorest values in vertical jump and sit-and-reach test. Those people with normal BMI had better balance ability than that of overweight and obese people. CONCLUSION: The rates of overweight and obesity in Guangzhou adult show a high level. The physical functions and qualities may be improved when the body mass increases or decreases in a certain range, but obesity has impact to those values.
ABSTRACT
AIM: To investigate the pharmacodynamic effects of Huahong Capsule on the anti-bacteria,anti-inflammation,antipyretic and analgesic effects. METHODS: The death rate of mice infected by staphylococcus aureus or Escherichia coli was observed to investigate the antibacterial effects.Crotonoil-induced auricle edema,cotton ball-induced granuloma and trauma-induced toe congestion were performed to investigate the anti-inflammatory effects in mice.Endotoxin-induced fever was performed to observe the antipyretic effect in rabbit.Mouse twisting numbers induced by acetic acid,mouse pain threshold after heat stimulation and rat twisting numbers of dysmenorrhea were observed to investigate the analgesic effects. RESULTS: Huahong Capsule had a tendency to decrease the death rate of mice infected by bacteria.It could remarkably inhibit edema of auricle of ear,formation of granuloma and toe congestion in mice.It decreased obviously the temperature raised by endotoxin in rabbit.It could reduce mouse twisting numbers and prolong pain thresholds. CONCLUSION: Huahong Capsule has pharmacological effects in accordance with its clinical functions and uses.
ABSTRACT
Objective To understand endemic diversity on schistosomiasis transmission after reserving plain for flooding. Methods In two study pilots, Jicheng and Qingshanhu, epidemiological factors were investigated longitudinally, and the effectiveness of the interventions was evaluated. Results The infection rates of mobile people who engaged in activities in the discarded plain were increased year by year. The density of infected snails was high. The snail habitats increased significantly in Jicheng, but decreased in Qingshanhu. The infection rate and number of livestock pastured in the discarded plain increased. In the discarded plain, most of the mobile people came from the local areas, and main activities for water contact were fishing and pasturing. About 90% of local residents migrated into endemic areas, and the others into non-endemic areas. Conclusions The discarded plains were evolving to a serious transmission zone of schistosomiasis. Interventions combined with agriculture and fisher productions can decrease snail-spreading. Schistosomiasis examination and chemotherapy for the migrants to non-endemic areas are vital.
