[Effect of comprehensive control on parasitic diseases in demonstration plot of Hainan Province].

OBJECTIVE: To evaluate the effect of control on soil-transmitted nematode infections in the demonstration plot of integrated control on parasitic diseases, Hainan Province. METHODS: The plot (county) was divided into east, west, north, south and central areas and the villages in these areas were selected with the random sampling method, and then the residents in these villages were investigated with Kato-Katz technique for soil-transmitted nematode infections and with questionnaires for knowledge, attitude and practice (KAP) and so on before and after the implementation of the control measures. All the results were analyzed and compared statistically. RESULTS: Compared with the results of the baseline survey, the overall infection rate of soil-transmitted nematode decreased by 68.66%. The infection rates of soil-transmitted nematode in the male and female decreased by 69.56% and 67.73%, respectively, and the rates in the children and adults decreased by 70.51% and 68.09%, respectively. The infection rates of Ascaris lumbricoides, Trichuris trichiura and hookworm decreased by 95.87%, 90.00% and 65.22%, respectively. The awareness rate of health knowledge increased by 115.23% and the qualified rate of health behavior increased by 51.61%. CONCLUSION: The remarkable results of soil-transmitted nematodiasis control have been achieved in the demonstration plot of integrated control on parasitic diseases, Hainan Province.

Controlled clinical trials on the treatment of lumbar disk herniation by Dingweiban and Xieban manipulation / 中国骨伤

<p><b>OBJECTIVE</b>To observe and compare the clinical effect of Dingweiban and Xieban manipulation, and to compare the change of the deviation of spinous processes between two methods.</p><p><b>METHODS</b>One hundred and twenty-two cases were divided into two groups. Sixty-two cases were treated with Dingweiban manipulation method and 60 cases by Xieban manipulation. The changes of Fairbank scores, the clinical effects and the difference of the deviation of the spinous processes (L3, L4, L5) from the lumbar posterior-anterior X-ray were compared.</p><p><b>RESULTS</b>The scores before and after treatment and 3 months after treatment were compared. There were significant differences between two groups (P < 0.05) by nonparametric test. The result of Dingweiban manipulation group: 53 cases cured, 5 cases better, 3 cases effective and 1 case no effect. The result of clinical Xieban manipulation group: 43 cases cured, 6 cases better, 7 cases effective and 4 cases no effect. The clinical effects had significant differences after treatment and 3 months after treatment (P < 0.05, P < 0.0l) by nonparametric test. After the first treating, there was clear difference of the deviations' distance of the L4 spinous process compared with the Xieban manipulation group (P < 0.05). After the last treating, there were clear differences of the deviation distance of the L4 and L5 spinous processes compared with the Xieban manipulation group (P < 0.05, P < 0.01).</p><p><b>CONCLUSION</b>Dingweiban manipulation is better than Xieban manipulation in effects and has influence on the deviation of spinous processes, especially for the L5 spinous process.</p>
