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 explore the clinical application value of serum procalcitonin (PCT) detection in diagnosis of neonatal infection disease.Methods The serum PCT,CRP values,routine blood test,blood cultures of 50 children with suspected infection was detected at admission and five days after admission.According to the clinical manifestations and the test results,50 children were divided into the bacterial infection group (32 cases) of and non-bacterial infection group (18 cases),and the value of PCT,CRP,routine blood test,blood culture was compared.Results Of bacterial infection group at admission,the serum PCT values in 27 cases were more than or equal with 2μg/L,white blood cell (WBC) increased in 6 cases,CRP of 7 cases were positive,blood cultures (3d) of 4 cases were positive,and of non-bacterial infection group at admission,the serum PCT value in 2 cases were more than or equal with 2μg/L,WBC increased in 2 cases,blood cultures (3d) of 1 case was positive ; Of bacterial infection group 5 days after admission,the serum PCT value in 23 cases were more than or equal with 2μg/L,WBC increased in 15 cases,CRP of 6 cases were positive,blood culture (5d) of 9 case were positive,and of non-bacterial infection group 5 days after admission,the serum PCT value in 1 cases was more than or equal with 2μg/L,WBC increased in 3 cases,CRP of 4 cases were positive,blood culture (5d) of 1 case was positive.At admission the cases of WBC increasing,CRP positive,blood culture positive of the two groups had no statistically significant differences (x2 =0.50,0.19,0.62,all P ＞ 0.05),but the cases of the PCT value which was more than or equal with 2μg/L had statistically significant differences between the two groups (x2 =25.30,P ＜ 0.05).5 days after admission the cases of WBC increasing,PCT,blood culture positive of the two groups had no statistically significant differences (x2 =4.39,20.30,8.56,all P ＜ 0.05),but the cases of the CRP value significant differences between the two groups (x2 =0.83,P ＞ 0.05).Conclusion The detection of serum PCT can be used as an important index of diagnosis for early neonatal infections,and its sensitivity and specificity are better than,blood routine and blood culture.

Objective:Cardiac index(CI) and mixed venous oxygen saturation SvO2 were studied in 85 patients undergoing coronary artery bypass grafting(CABG). Methods: Measurement of CI and SvO2 was carried out with a fiberoptic ballon-tip thermodilation pulmonary artery catheter. Fentanyl-based anesthesia was applied in all patients. Hemodynamic parame-ters were obtained prior to anesthesia induction as the baseline, after endotracheal intubation, after stemotomy, after weaning of cardiopulmonary bypass, at 6 and 24h after operation. Results: CI and SvO2 increased or was not changed at all time intervals, compared with the baselines. The changes of SvO2 correlated well with those of CI. Conclusion: The results suggest that continuous monitoring of SvO2 may be useful to predicting alteration in CI in patients undergoing CABG.

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 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 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 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.
