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.

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.

This paper reviewed the epidemiology, pathogenesis of post-ischemic-stroke cognitive impairment and the correlation analysis between the lesion and cognitive impairment under imaging guidance.

The behavioral performance and mechanism of spatial acalculia were reviewed in this paper. Meanwhile, the brain mechanism and cognitive impairment are also preliminarily introduced.

Acalculia has been defined as an acquired disturbance in number processing and computational ability. Acalculia which caused by various diseases has a great effect on activity of daily living. This article presents a review of Standardized Tests of Acalculia(including EC301 calculation and number processing battery, Number Processing and Calculation battery and Johns Hopkins Dyscalculia Battery) and cognitive rehabilitation for acalculia. The main strategy for rehabilitation is to re-teach lost knowledge via extensive practice according to the evaluative results. Those are described in 5 domains: the understanding of numbers, number transcoding, arithmetical facts, complex calculation and mathematics applications.

Objective To investigate the attention span in patients with brain injury.Methods Twenty-seven patients with brain injury and 34 normal adults who were matched in age and in years of education were tested with visual span and digit span to assess the attention span. The score relies on the max number that the subject can answer correctly.Results Both visual span and auditory span in the patients were significantly less than that in control group (P＜0.01), but they were not significantly correlated (P＞0.05).Conclusion The visual span and auditory span were impaired in different degree in patients with brain injury.

ObjectiveTo observe the characteristic of reaction times (RTs) in the brain injury children.Methods65 children with brain injury, including 50 cerebral palsy (CP) cases, 13 brain trauma (BT) cases and 2 other cases, were selected as the experimental group, and 29 age-matched normal children as the control group. Children of two groups were tested by the eye-hand visual reaction times (VRTs), and children of the experimental group were also tested with Wechsler preschool and primary scale of intelligence (WPPSI), Wechsler intelligence scale for children (WISC-R) and comprehensive function assessment.ResultsThe VRTs of the experimental group children was significantly slower than that of the control group (P<0.01). There was no significant difference in VRTs test between CP and BT children (P>0.05). The motor time of VRTs of the severe subjects in the experimental group was significantly slower than that of moderate and light subjects (P<0.01). There was a negative correlation between VRTs and the scores of IQ, PIQ and the comprehensive function assessment.ConclusionThe attention and the motor speed of muscles are abnormal in children with brain injury.

Objective To investigate the preventive effect of fine management of hospital infection quality of obstetric rooming-in,in order to reduce the incidence of hospital infection.Methods Fine management run through each link of the hospital infection control from 2010,including a sound management system,strict implementation of the regulations for the operation and management of hand hygiene system,improvement of the building layout and work flow,strengthening the company staff and the ward environment management and monitoring,and make the management of hospital infection more standard.Results The obstetric rooming-in nosocomial infection rate decreased from 3.90％ in 2010 to 0.78％ in 2012.Fine management significantly reduced the incidence of nosocomial infection in our hospital.Conclusions The implementation of fine management in obstetric rooming-in is conducive to the effective control of nosocomial infection and promotion of maternal and child safety.

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.
