Objective　This was a follow-up study of suicidal patients to assess the influence over time of different risk factors.Method　A cohort of 73 patients admitted to a psychiatric department after a suicide attempt was followed-up for 5 years.Results　In total,61.6% reattemped,15.1% of which had committed suicide during the follow-up.The rist factors for suicide included history of family psychiatric or suicide,and a poor social support,et al.Conclusion　The results suggest a high repetition rate of suicide attempters in the psychotic patients who had previous suicidal behaviour and them positive family history.The preventive strategy to suicide in patients,such as set up good social network and should pay mroe attention to psyciologic rehabilitation period after discharge.

Objective To study the CT and MRI features of peripheral primitive neuroectodermal tumor(PNET).Methods CT and MRI appearances of 10 patients with PNET pathologically proved were analyzed retrospectively.All cases underwent CT scan and 2 cases underwent MR imaging examination.There were 5 men and 5 women,the age ranged from 11 years to 54 years old(mean 24 years).Results The tumors were located in the chest wall(n=4),abdomen and sinus(n=2,each),cervical vertebra and humerus(n=1,each).The lesions in the chest wall and abdomen appeared as larger masses(5~16 cm in diameter).The masses were circular and lobulated with heterogeneous density and in company with bone destruction or periosteal reaction.The solid masses were enhanced after contrast medium administration.The lesions in the sinus showed the soft tissue mass with bone erosion.The lesions in bone demonstrated local iso-intensity on T1WI,hyper-intensity on FSE T2WI and on FATSAT T2WI.There were distant metastasis in 3 cases.Conclusion The clinical and imaging features of pPNET in chest wall were more specific than in other locations.CT and MRI can showed intra-tumor structure,and are helpful in delineated the extent of tumor,predicting resectability and monitoring treatment.

Objective To develop psychosocial skills training module for schizophrenic outpatients.Methods Structured psychosocial skills training program, which were made according to community rehabilitation plan for schizophrenia, featured convenience and well operability. Subjects were 96 of 204 schizorenic outpatients in remission who were randomly assigned to receive psychosocial skills training combined medicine(observation group) or medicine only(control group) and followed up by 24 months. The changes during treatment were evaluated by positive and negative syndrome scale(PANSS), Social Disability Screening Schedule(SDSS) and patients' cognition function were also evaluated longitudinally. Results Relapse rate of control group (37%) is higer than observation group (17.7%, P＜0.01). After Last Observation Carried Forward(LOCF), control group showed higer scores than observation group on positive syndrome (8.34±2.04 vs 7.66±0.97), negative syndrome(9.15±1.97 vs 813±1.15), total score (37.64±5.58 vs 34.79±3.64) and Social disability (2.81±1.90 vs 2.07±1.47) (P＜0.01); observation group also showed a significant progress on cognition function(P＜0.05). Conclusion This trial demonstrated the efficacy of the easy-operating structured psychosocial skill training grogram in preventing relapse and improving social adoptive function for schizophrenia.

Objective To investigate the application of enhanced recovery after surgery (ERAS)in the nursing of thoracolumbar fracture with nerve injury.Methods A retrospective case-control study was conducted to analyze the clinical data of 64 patients with bilateral thoracolumbar fractures with nerve injury admitted to the Chongqing General Hospital from November 2013 to November 2017.There were 52 males and 12 females,aged 26-62 years,with an average age of 43 years.The injured segments were located at T11-T12in 28 patients,T12-L1 in 15 patients,L1-L2 in 10 patients,and L2-L3 in 11 patients.According to the Frankel classification of neurological function,there were 14 patients at grade A,18 at grade B,24 at grade C and eight at grade D.All patients were treated with common pedicle screw placement under direct vision combined with dome shaped decompression through small incision.Among the patients,32 received ERAS rehabilitation nursing (ERAS group) and 32 received routine rehabilitation nursing (routine group).The incidence of complications,hospitalization time,hospitalization expense,patients' satisfaction with nursing work,visual analogue scale (VAS),Oswestry dysfunction index (ODI) and Frankel classification of neurological function at 3 months after operation were compared between the two groups.Results The patients were followed up for 8-12 months [(10.2 ±1.3) months].In the ERAS group,one patient had pulmonary infection;in the routine group one patient had wound infection,one had bedsore,and one had venous thrombosis in lower limb (P ＜ 0.01).The hospitalization time of ERAS group was significantly shorter than that of routine group [(9.3 ± 1.2)days:(15.6 ± 1.8) days] (P ＜ O.01).The hospitalization expense of ERAS group was significantly lower than that of routine group [(52 ± 13)thousand yuan (RMB) vs.(63 ± 17) thousand yuan (RMB)](P ＜ 0.05).The satisfaction rates of ERAS group and routine group were 84％ (27/32) and 56％ (18/ 32),respectively (P ＜ 0.05).At 3 months after operation,the ERAS group had significantly lower VAS [(2.6±1.2)pointsvs.(3.8±1.5)points] and ODI (11.4±2.1)pointsvs.(15.8±2.5)points]than the routine group (P ＜ 0.05 or 0.01).At 3 months after operation,according to the Frankel grading,there was one patient at grade A,five at grade B,nine at grade C,five at grade D,and 12 at grade E in the ERAS group;while there were three patients at grade A,seven at grade B,seven at grade C,nine at grade D,and six at grade E.The recovery rate of Frankel grade 1 and/or above in ERAS group was significantly higher than that in routine group [97％ (31/32) vs.91％ (29/32),P ＜0.05].Conclusion Rehabilitation nursing measures of ERAS can help reduce perioperative complications,hospitalization time and hospitalization expenses,relieve pain,promote functional recovery,and gain satisfactory feedbacks from the patients.

Objective: To investigate the positive rate for 2019-nCoV tests and co-infections in Wuhan district. Methods: A total of 8 274 cases in Wuhan were enrolled in this cross-sectional study during January 20 to February 9, 2020, and were tested for 2019-nCoV using fluorescence quantitative PCR. Both respiratory tract samples (nasopharynx, oropharynx, sputum and alveolar lavage fluid) and non-respiratory tract samples (urine, feces, anal swabs, blood and conjunctival sac swabs) were collected. If both orf1ab and N genes are positive, they are classified as nucleic acid test positive group; if both orf1ab and N genes are negative, they are classified as negative group; if single gene target is positive, they are classified as suspicious group. Individuals were divided into male group and female group according to sex. At the same time, 316 patients were tested for 13 respiratory pathogens by multiplex PCR. Results: Among the 8 274 subjects, 2 745 (33.2%) were 2019-nCoV infected; 5 277 (63.8%) subjects showed negative results in the 2019-nCoV nucleic acid test; and 252 cases (3.05%) was not definitive (inconclusive result). The age of cases with COVID-19 patients and inconclusive cases was significantly higher than that of cases without 2019-nCoV infection (40 vs 56, t=27.569, P<0.001; 52 vs 56, t=6.774, P<0.001). The positive rate of 13 respiratory pathogens multiple tests was significantly lower in 104 subjects who were positive for 2019-nCoV compared with those in subjects who were negative for 2019-nCoV test (5.77% vs 18.39%, χ²=24.105, P=0.003). Four types of respiratory tract samples and five types of non-respiratory tract samples were found to be positive for 2019-nCoV nucleic acid test. Conclusion The 2019-nCoV nucleic acid positive rate in male is higher than in female. Co-infections should be pay close attention in COVID-19 patients. 2019-nCoV nucleic acid can be detected in non-respiratory tract samples.

BACKGROUNDBased on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.

METHODSThe Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.

RESULTSA total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).

CONCLUSIONWe first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.
