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.

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.

Objective To study the impact of nursing intervention on the sleep quality of postoperative elderly patients who had sleep disorder. Methods 260 cases of postoperative elderly patients with sleep dis-orders were randomly divided into the experimental groupand the control group with 130 cases in each group. Conventional care was given to the control group, the experimental group received appropriate nursing interven-tion such as psychological nursing, rehabilitation,etc. Pittsburgh sleep quality index (PSQI) was used to evaluat-ed sleep quality of two groups before and after intervention, t test was adopted. Results No difference was seen in each sleep index in the two groups. While each index evidently alleviated after intervention in the ex-perimental group and was better than those of the control group. Conclusions Nursing interventions have certain effects on improving sleep quality of postoperative elderly patients with sleep disorders.

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 improve the treatment effect of primary hepatic cancer (PHC). Methods　Analysis of the influential factors on treatment effect of PHC in China, and propose the countermeasure. Results and Conclusions　The main factors influencing the treatment effect of PHC in China are the followings: (1) Most patients with PHC of subclinical type failed to be diagnosed and treatment in time. (2) As a wrong idea PHC has been considered an “uncurable disease", so the treatment strategy is nagative. (3) Unsuitable choice of treatment resulted in some PHC unable to be resected. (4) Intraoperative massive bleeding due to unskill-operative techniques, increase the postoperative morbidity and mortality. (5) The manner of treatment is not positive for PHC patients with portal cancer thrombosis, bile duct cancer hteombosis and portal hyperlension. (6) Combined therapy can not be used or unsuitably used. The following things should be done in order to improve the treatment effect of PHC: (1) Strengthening improving the health-protective consciousness of people and regular examinaton of “high risk" population. (2) Renewing the professional knowledge in time to improve the level of diagnosis, treatment and operative techniques of medical personnel. (3) strengthening the basic medical research to make a break through in PHC treatment.

Layered anatomy is a both ancient and novel conception, which is derived from topographic anatomy.Topographic anatomy and phylembryogenesis are basic academic knowledges of layered anatomy.With the development of laparoscopic surgery and robotic surgery, less bleeding, more meticulous dissection, faster postoperative recovery and lower recurrence rate are required in surgical operation, because of which layered anatomy is mentioned and valued again.Organs in abdominal cavity are composed of different layered tissues,between them are loose connective tissues which are poor in vessels.Layered anatomy in surgical operation can avoid the en bloc dissection of organs, which not only reach total lesion dissection, but also avoid hurting surrounded normal tissues, showing the best surgical results.

Crohn's disease is one of the main types of inflammatory bowel disease,some patients with Crohn's disease may be beyond the control of the medical complications,finally had to accept surgical treatment.This paper reviews the Crohng disease patients of surgical indications,gastrointestinal complications related to the classification,risk factors,prevention and treatment countermeasure research,designed for Crohn's disease indications for surgery decision and postoperative gastrointestinal complications in the diagnosis,perioperative treatment and prevention to provide some guidance and help.

Objective To observe the effect of external fixator combined with limited internal fixation in the treatment of complex ankle fractures.Methods According to the digital table,65 patients with complex ankle fracture were randomly divided into treatment group(33 cases) and control group(32 cases).The treatment group was treated with external fixator combined with limited internal fixation,the control group was treated with internal fixation.All patients were followed up for 5 to 20 months.The curative effect and incidence rate of complication of the two groups were observed.Results The excellent rate of the treatment group was 84.85%,which was higher than 62.50% of the control group,the difference was statistically significant(x2=4.20,P<0.05).The incidence rate of complications in the treatment group was 3.03%,which was lower than 18.75% of the control group,the difference was statistically significant(x2=4.18,P<0.05).Conclusion External fixator combined with limited internal fixation can effectively treat complex ankle fractures,the method can not only make patients satisfied with the reduction effect,but also the internal fixation complications such as infection are minimized,the clinical value is extremely high,it is worthy of wide application.

Objective To explore the correlation of cognitive impairment with ischemic strokeinducing cerebral artery,in order to predict and find the correlations between different cognitive dysfunction and different intracranial arterial occlusion.Methods We used Montreal Cognitive Assessment (MoCA) to evaluate neuropsychological statuses in the 250 patients,who developed first time acute myocardial infarction for 2 weeks.MoCA scores and other neuropsychological cognitive assessment scores were recorded.Patients were grouped by the location of intracranial arterial occlusion.The neuropsychological cognitive assessment results were analyzed between groups.Results Middle cerebral artery occlusion was correlated with impairments of visual spatial/executive,attention,language and memory (B=-1.875 ～-1.094,P＜0.05).Anterior cerebral artery and vertebral basilar artery occlusion had correlations with attention impairment (B =-3.977,B =-1.833,P＜0.01).Posterior cerebral artery occlusion could cause visual spatial/executive,language and memory impairment(B=-1.714 ～-1.095,P＜0.05).No correlation of cognitive impairment characteristics with anterior choroidal artery occlusion was found.Conclusions Different arterial occlusion can cause different characteristics of impairment in cognitive function,which can help to predict cognitive impairment after sub-acute stroke.It suggests that some cognitive assessments must be conducted in sub-acute stroke management.
