Field application of mosquito nets impregnated with Fendona (alphamethrin) was con-ducted in Jiangpu,Liuhe and Yizheng counties (city) during 1992 in order to control malaria and mosquito vector. Three groups were set for control,i.e. ,using mosquito nets impregnat-ed with deltamethrin, DDT spraying,and a group without preventive measures. The result showed that density of mosquito vector declined significantly after using of mosquito nets im-pregnated with Fendona. Mosquito density declined by 71. 58% ,the long-term efficiency last-ed more than 4 months,and local malaria incidence declined by 72. 73%. The effect of this measure was similar with that of using mosquito nets impregnated with deltamethrin, and was much better than that of DDT spraying. Since Fendona is a cheap,odourless,and effec-tive insecticide it is worthwhile to be recommended in malaria control program in the field.

Objective To investigate the characteristics of pathogenic bacteria and drug resistance and susceptible factors of pulmonary infection in patients with severe brain injury and to provide a guideline for the prevention and control of infection.Methods Bacteria culture results combined with clinical data of pulmonary infection in patients with severe brain injury were analyzed retrospectively in our hospital from Jan.2004 to Dec.2008.Results The patients with severe brain injury were often complicated by pulmonary infection.Gramnegative bacilli were main pathogenic bacteria leading to pulmonary infection ( 74.8% ),including pseudomonas aeruginosa ( 21.0% ),Escherichia coli ( 16.5% ),baumanii ( 13.6% ),pneumobacillus ( 7.7% ),enterobacter cloacae (6.3% ) and others.Thirty-nine Gram-positive bacilli were observed including Staphylococcus anreus,coagulase negative staphylococcus,enterococcus and others.There were 21 fungus infection observed.Conclusions Overall and systematically monitoring the condition of pathogenic bacteria distribution and drug resistance of pulmonary infection in patients with severe brain injury have important significance to select antibiotics and effectively prevent and control pulmonary infection.

Objective To understand the basic situation of blood donors and their anti-HIV antibody screening in a hospital of Madagascar during 2008- 2009 in order to provide the reference information for giving better medical aid and promoting the devel-opment of the clinical transfusion in Madagascar.Methods The blood doner′s personal informations were understood by inquiry and the anti-HIV antibody was detected by the rapid testing,the results were recorded,the constituent ratio of the data was calcu-lated and the chi-square test was performed.Results There were 2 298 blood donors including teenages less than 15 years old dur-ing 2008-2009,female doners were more than male donors,among them 366 cases were pregrant women.The blood donors from village were more than those from city,the education level was dominated by the middle school students,accounting for 51.65%. There were 22 tuberculosis patients in 2008,none in 2009.The detection rate of anti-HIV antibody was 0.04% for these 2 years. Conclusion The protection on the blood donors in Africa area is not optimistic.The phenomenon of pregrant women and teenages as the blood donors exists in Madagascar.

Under the high pressure of employment, traditional teaching method that is based on inculcating the knowledge to students does not adjust current condition any more. So, we start to looking for a new, more suitable way of teaching.--Project Based-on Learning, and have analyzed the advantages in health information technology teaching by construction doctrine in combination with the concept and principle in wedlock construction. At the same time we introduce project Based-on Learning in concrete application to find a way to put the theory into practice.

Objective To investigate the correlation between adiponectin, CRP and homocysteine (Hcy) and evaluate its mechanism in acute cerebral infarction. Methods Serum adiponectin, hs-CRP,Hcy, blood lipid, FPG and blood pressure were measured in eighty patients with acute cerebral infarction ( cerebral infarction group) and eighty healthy persons ( control group). Results In cerebral infarction group, serum hs-CRP, Hcy, TG , and systolic pressure were significantly higher than in control group ( P ＜0. 05) , while serum adiponectin were significantly lower than in control group ( P ＜0. 05). Serum adiponectin levels were negatively correlated with Hcy( r = -0. 453) , hs-CRP ( r = -0. 397) ,TG( r = -0. 321) , FPG( r = -0. 318) and systolic pressure ( r = -0. 288). Conclusion There is correlation between adiponectin, Hcy, hs-CRP, glucose and lipid metabolism and blood pressure, which plays a role in occurrenc and development of acute cerebral infarction.

Object To study the apoptosis induced by sodium artesunate (SA) in human liver cancer cells and its molecular mechanism. Methods Induction of the apoptosis was analyzed by fluorescent microscope, transmission electron micrograph and flow lytometry based on drug treated BEL-7402. Expressions of p53, p21 and bc1-2 were determined by Western blot. Results The expression level of p53 and p21 had no change remarkbly, but the expression level of bc1-2 was reduced compared to that of the control group after the human liver cancer cells were treated by SA. Conclusion The apoptosis in human liver cancer cells (BEL-7402) may be induced by SA, the molecular mechanism of apoptosis may be p53-independent, that is no relative to p53 and p21. Otherwise, it is relative to bc1-2 down-regulation.

Objective To elucidate the effect of rehabilitation training on visual reaction times of children with brain injury. Methods Fifty-one children with brain injury recruited for the observation group were observed, 29 age-matched normal children served as the controlsubjects. All the children in both groups were tested in terms of the eye-hand visual reaction times(VRTs). All the patients were given rehabilitation treatment. Results Before rehabilitation treatment, the VRTs of the observation group were significantly slower than those of the control group (P0.05). Conclusion The attention and the motor speed were abnormal in children with brain injury, rehabilitation treatment can improve the reaction times significantly. The test of RTs could be of great importance in the evaluation of neurobehavior and therapeutic effect for children with brain injury, because of its easiness, sensitiveness and objectiveness in clinical application.

A method for separation and determination of vitamin E from egg by reverse phase HPLC was introduced.The accuracy and precision of this method were much better than the ordinary method. Standrd deviation of retention time and peak area were 0.012 and 146.92, and the corresponding coefficient of variation was 0.22% and 0.44% respectively. The recovery rate was 100.6 ?3%. This method was suitable for measuring VE in egg, milk powder and cod-liver oil.

Objective To explore the effect of Chitosan gel (Ⅲ) on the complications from Milligan-Morgan hemorrhoidectomy for treatment of severe mixed hemorrhoids.Methods Seventy-six patients with severe mixed hemorrhoids were randomly divided into treatment group and control group with 38 cases in each group. All patients from the two groups were treated with Milligan-Morgan hemorrhoidectomy. Then Chitosan gel (Ⅲ) was used in the treatment group. The two groups were compared in terms of curative effect, pain level, complications and hospital stay.Results There was no significant difference in the curative effect (P>0.05). But the scores on pain level, hemtochezia, infection and edema of the treatment group were all significantly lower than those of the control group (allP<0.05) and the hospital stay was significantly shorter than that of the control group (P<0.05).Conclusions In the treatment of severe mixed hemorrhoids by Milligan-Morgan hemorrhoidectomy, Chitosan gel (Ⅲ) is effective in relieving pains, reducing hemorrhage, edema and preventing infections and therefore shortens the hospital stay. In view of nursing, it is critical to perform mental care as well as close observations on complications.
