BACKGROUND: Osteonecrosis of the femoral head (ONFH) following internal fixation of femoral neck fractures is difficult to be cured in clinic.OBJECTIVE: To analyze the literatures concerning ONFH in patients with femoral neck fractures treated with screw internal fixation in recent 15 years, and to summarize the research progress in views of epidemiology, etiology, diagnosis,treatment and rehabilitation.METHODS: Databases of CNKI, WanFang, CqVip, PubMed, Medline, Web of Science were searched with the keywords of femoral neck fracture, osteonecrosis of femoral head, osteonecrosis, internal fixation, internal fixation with screw in English and Chinese, respectively. Afterwards, the reviews and case reports were excluded. RESULTS AND CONCLUSION: (1) A total of 54 eligible articles addressing the ONFH following internal fixation for femoral neck fractures were included, and the incidence of ONFH varied from 8.1% to 37.2%, which was found at an average of 17 months after injury. (2) ONFH was found to be related to age, preoperative fracture displacement, preoperative traction,reduction condition, time from injury to operation, elderly patients companied with other diseases, older patients undergoing removal of the screws, closed or open internal fixation, restored time postoperatively, high body mass index, hyperlipidemia, season, and depression. (3) Early prevention and remedial surgery were used to treat ONFH. (4) The patients without weight-bearing activities at 3-6 months postoperatively could be beneficial for functional recovery. (5) These results suggest that choosing appropriate surgical programs and rehabilitation plan can reduce the incidence of ONFH and achieve good treatment outcomes, such as reasonable preoperative planning, standardized operation skills, correct diagnosis and treatment, proper postoperative rehabilitation and good doctor-patient cooperation.

Objective To explore if any rules in electrocardiogram changes after transcatheter closure of perimembranous ventricular septal defects ( PMVSD ) . Methods We included all the 358 patients who have accepted transcatheter closure of PMVSD in our hospital between July 2006 to October 2014 and the electrocardiogram (ECG) done in hospital and during follow up in 1,3, 6 and 12 months after operation were all reviewed. Results No changes were found in heart rates and electrical axis during follow-up as compared to preclosure ECG. PR interval was shorter, the QRS duration and QT interval were longer than preclosure. Incidence rate of arrhythmia was 38. 0% ( 136/358 ) and incidence rate of serious arrhythmias ( including Ⅱ° or Ⅲ° atrioventricular block and complete left bundle branch block) was 5. 0%(18/358). Among the 180 patients who had ECG done in all follow up between the first 12 months post closure, the rates of new developed arrhythmias was 12. 8% ( 23/180 ) and severe arrhythmia was 0. 6%(1/180) during follow-up. Conclusions Incidence rate of serious arrhythmias after transcatheter closure of PMVSD is low and most patients have good clinical outcome.

Objective To explore the personality change in patients with epilepsy during the interictal period and the correlation between clinical features and personality change. Methods One hundred and fifteen patients with idiopathic or cryptogenic epilepsy were chosen as the epileptic group and 42 age- and sex-matched healthy subjects served as controls. All participants were evaluated by Mini Mental Status Examination and Brief Psychiatric Rating Scale to ensure the normality of cognition and mental state.Personality was evaluated by adult version of Eysenck Personality Questionnaire (EPQ)in interictal epilepsy patients and healthy controls.Scores of psychoticism (P),extraversion (E),neuroticism (N) and lie (L)were obtained using computer software. Pearson correlation analysis and logistic regression were used to investigate the scores of EPQ and influential factors.Results P and N scores were significantly elevated in epilepsy patients compared with controls ( P scores:50.48 ± 9.55 vs 46.59 ± 7.28,N scores:51.13 ±12.89 vs 46.83 ± 9.40 ; t =2.374,2.266,both P ＜ 0.05 ),while E scores were significantly decreased (51.74 ± 10.74 vs 60.37 ± 9.84;t =- 4.511,P ＜ 0.01 ).There were no significant differences in L scores.Multivariate analysis showed that disease duration was independently correlated to P scores (β =0.043,P＜0.05),while education was correlated to E scores (β =0.109,P ＜ 0.05 ).There were no significant correlations between personality scores,patient age,gender,age of onset,frequency,seizure type,National Hospital Seizure Severity Scale scores,family history,history of status epilepticus and antiepileptic drugs usage.Conclusions High psychoticism and neuroticism and low cxtraversion scores are correlated to patients with epilepsy during the interictal period.Disease duration is an independent risk factor for psychoticism personality,and education level is an independent risk factor for extraversion personality in epilepsy patients.

Objective To evaluate the effect of minimally invasive therapy for treating intraventricular hemorrhage.Methods The minimally invasive therapy with unilateral or bilateral drainage were received according to quantity and shape of intraventricular hemorrhage.Results It was operated 22 cases with unilateral drainage and 28 cases with bilateral drainage in the 50 cases intraventricular hemorrhage.Death was 3 cases and mortality rate was 6% in the minimally invasive therapy.ADL1 15 cases(30%),ADL2 18 CRSeS(36%),ADL3 8 cases(16%),ADLA4 cases(8%),ADL5 2 cases(4%)in leave hospital.Conclusion Minimal invasive therapy of intraventrieular hemorrhage has great superiority,such as it can operate simple,trauma mild,decrease complications and enhance curative effect.It can generalize in the basic hospital.

Based on introducing the total price adjustments in pilot cities and analyzing the existing problems,it further analyzes the objectives of the total price adjustment allocation of medical service items,the characteristics of various types of medical service items and the possible impact of price adjustment,concludes that the priority of the total price adjustment allocation should be as follows:new items,special tasks,complex items,general items,and medical services for special needs.It also combines the practical experience of the pilot cities to establish the total price adjustment allocation mechanism,and provides opinions on the total price adjustment allocation before the dynamic adjustment of medical service prices in the future.
