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 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.

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.

The robotic surgical system can provide a stable, clear and magnified three-dimensional view, filter the surgeon's hand tremor, and hold robotic arms with multiple degrees of freedom to ensure flexible and stable operations, which overcomes the shortcomings of traditional laparoscopy. Although the robotic surgical system has been widely used in surgical fields such as urology, obstetrics and gynecology, its role in hepatic surgery has not been fully recognized. In this article, based on the relevant literatures and their own experience, the authors briefly discuss the indications of the application of robotic surgical system in liver surgery, safety and efficacy of robotic liver resection, learning curve of robotic hepatectomy, difficult robotic hepatectomy, the cost of robotic liver resection and other issues.

Objective To explore the clinical value of heart-type fatty acid binding protein testing (H-FABP) in the diagnosis of early myocardial ischemia injury.Methods One hundred and eighty cases diagnosed with myocardial ischemia from January 2016 to December 2016 were selected as the experimental group,then according to the disease time,the subjects were divided into the earlier group(≤3 h),middle group(3~6 h)and later group(≥6 h),each group 60 cases.180 cases with healthy physical examination results were enrolled in the control group.The concentration of serum H-FABP and IMA were detected in order to analyze the clinical value comprehensively.Results Compared with the control group,the concentration of serum H-FABP ((11.54±4.31) μg/L) and IMA ((92.72±5.31)U/ml) in the experimental group increased greatly,the differences were statistically significant(t=2.305,3.001,P<0.05).Among the subgroups in the experimental group,the concentration of IMA was the highest in the early stage and decreased in the middle and later stages,and there were significant difference between the earlier group and later group(t=2.326,P<0.05).The concentration of serum H-FABP and IMA in the experimental group and control group were positively correlated (r=0.9237,P<0.05).Positive detection rate analysis showed that the positive rates of H-FABP and IMA among the subgroups were above 80.00%,and the positive rate of combined detection was obviously improved (P<0.05).The clinical diagnosis was used as the gold standard,the Kappa of the results of H-FABP detection and clinical diagnosis was 0.85 (P<0.05).Conclusion H-FABP has a positive clinical significance in the diagnosis of early myocardial ischemia,as IMA has high positive detection rate,and has high consistency with clinical diagnosis results,it can effectively reduce the misdiagnosis rate and combined detection can reduce the rate of missed diagnosis.

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.
