Objective To observe the therapeutic effect of minimally invasive evacuation of intracerebral hematoma in dog model of cerebral hemorrhage by using Purdy score, serum levels of neuron-specific-enolase (NSE) and numbers of perihematomal apoptotic cells. Method Twenty dogs were selected to prepoxe the model of cerebral hemorrhage, and they were randomly divided( random number) into minimally invasive treatment group and control group. Minimally invasive procedures were performed to evacuate the hematoma in minimally invasive treatment group in 6 hours after the models were established. The dogs of control group only received medical treatment. Purdy score and serum levels of neuron-specific-enolase were determined on 1,3,5,7 days after the evacuation of the hemotoma and apoptotic cells were counted after the dogs were sacrificed at 7 days after operation. All the results were compared with control group. Purdy score and serum levels of neuron-specific-enolase were compaired with variance analysis of repeated measurement design and apoptotic cells was compared with variance analysis of factorial design,the difference of the two groups showed with q test. P <0.01 showed the difference was significant. Results The Purdy scores in minimally invasive treatment group were 6.3 ± 1.702, 5.8 ± 1. 685,4.2 ± 1.762 and 4.1 ± 1.875 on 1,3,5 and 7 day after evacuation of the hematoma, significant difference was observed as compared with the control group(8.9 ± 1.632, 8.6± 1.342, 7.8±1.335, 7.9±1.468, P <0.01).The serum levels of neuron-specific-enolase were 0.632 ± 0.077, 0.721±0.771, 0.549±0.124 and 0.430 ±0.136 respectively in minimally invasive treatment group, while in the control group were 0.934 ± 0. 064, 0. 997 ±0.075, 0.986 ± 0.042, 0.874 ± 0.165, significant differences in serum levels of neuron-specific-enolase were found between the two groups(P < 0.01). The perihematomal apoptotic cells in minimally invasive treatment group(37.4 cells) was decreased significantly as compared with the control group(88.6 cells), with P < 0.01.Conclusions Minimally invasive procedures for evacuation of intracerbral hematoma might significantly reduce the neurological deficit score and decrease the serum neuron-specific enolase levels and numbers of apeptotic neurons.

Objective To observe the effects of stereotactic implanting depth electrode into the hippocampus on monitoring mesial temporal lobe epilepsy. Methods Thirteen patients with pharmacoresistant epilepsy were included in the present study.The epilcptogenic zone might be located in the hippocampus based on the symptoms and MRI data.Eight-contact depth electrode was implanted into the patients' hippocampus by stereotactic procedures to record the electroencephalogram(EEG).The duration of monitoring lasted for 24-72 hours or more,so as to be sure if the epileptogenic zone was located in the hippocampus,and to provide evidences for surgical resection of epileptic focus.Results Thirteen patients with mesial temporal lobe epilepsy underwent video electroencephalogram monitoring for 72 hours.Twentynine epileptic seizures in 7 patients were detected.Ictal EEG changes manifested as paroxysmal slow wave or spike and slow waves on the background.The epileptiform discharges started from some electrode points,and then propagated to others or the contralateral electrode. After 1-2 seconds of delay,high amplitude slow waves with the frequency of 3-4 Hz were observed on the ipsilateral scalp EEG. Clinical epileptic seizures were not detected in 6 patients during monitoring,depth electrode showed paroxysmal focal high amplitude slow wave or spike and sharp waves,scalp EEG did not find abnormality.Six of thirteen patients received surgical resection of epileptic foci,the outcome during follow-up of 3-8 months was satisfactory.Conclusions To record hippocampal EEG in patients with intractable epilepsy by stereotactic implanting depth electrode into the hippocampus might be a safe and reliable method.It might provide strong evidences for the diagnosis of patients with mesial temporal lobe epilepsy,and for the location of epilcptogenic zone.

Conclusions There are different kinds of intestinal pathogens in hospital sewage , which may lead to contamination of drug-resistant microorganisms in the environment .Therefore the hospitals should strengthen the quality of sewage treatment and improve the qualified rate of sewage disinfection .

Objective: To explore the turnover intention of nurses in Quzhou and its influential factors. Methods: From July to August in 2017 cross-sectional study and self-filled questionnaire are used to investigate 980 nurses from 7 hospitals in Quzhou, including two third-level hospitals and five second-level ones. T-test, F-test, Pearson and linear regression are used in data with the method of statistical analysis. Results: The total score of turnover intention of nurses was (14.95±3.17) points, and the index value was 62.27%, of which the turnover intention was above 78%. The analysis of Single factor showed that age (F=4.895) , Department (F=2.971) , title, nursing age (F=5.863) , self-assessment of physical conditions (F=4.092) were closely related to nurses’ turnover intention(P<0.05). According to Person’s correlation analysis, there are positive correlations between turnover intention and source of stressor, and moral distress (P<0.05) . Multiple linear regression showed that the nurses’ turnover intention was age, Department, health selfevaluation, stressor and moral distress. Conclusion The turnover intention of nurses is high, which is related to age, Department, self-evaluation of health, stressor and moral distress.

Objective To observe the clinical effects of arthroscopic reconstruction for anterior cruciate ligament ( ACL ) tear using tension-relieving technique and enhanced recovery after surgery ( ERAS ) . Methods Between May 2014 and June 2016, 80 patients with ACL tear were randomly di-vided into 2 equal groups. The experimental group was treated with arthroscopic reconstruction using hamstring tendon autograft and tension-relieving technique followed by ERAS; the control group was treated with arthroscopic reconstruction using hamstring tendon autograft only followed by conventional postoperative re-covery. The 2 groups were compared in terms of knee flexion angles at postoperative 2nd, 4th and 8th weeks, and the IKDC ( International Knee Documentation Committee ) , HSS ( Hospital for Special Surgery ) , and Lysholm scores at postoperative 3rd, 6th and 12th months. Results The 80 patients obtained an average follow-up of 12. 3 ± 1. 7 months. Arthroscopy one year postoperation revealed fine ACL growth without laxity or other complications in the experimental group. Joint stiffness appeared in one case at 2 months postoperation and ACL laxity was observed in 3 cases by arthroscopy at 12 months postoperation in the control group. The knee flexion angles at postoperative 2nd, 4th and 8th weeks, and the IKDC, HSS and Lysholm scores at postoperative 3rd, 6th and 12th months in the experimental group were significantly better than those in the control group ( P <0. 05 ) . In both groups, the IKDC, HSS and Lysholm scores at postoperative 3rd, 6th and 12th months and the knee flexion angles at postoperative 2nd, 4th and 8th weeks were all significantly im-proved than the preoperative values ( P <0. 05 ) . Conclusion In arthroscopic reconstruction for ACL tear, tension-relieving technique combined with ERAS can promote functional recovery of the knee and reduce postoperative complications, facilitating early recovery of sports function.
