Objective To explore job satisfaction degrees and the influencing factors among community nurses. Method General information questionnaire and the revised job satisfaction questionnaire were adopted in the investigation among 124 nurses from 28 community health service centers in Nanchong City between February to October 2016. Results The total score was (119.62 ± 15.37), at the moderate to high level. Of the eight dimensions, relationship with colleagues was scored the highest, and personal growth was the lowest. The influencing factors of the nurse's job satisfaction were found to be employment type, work positions, service duration in the community and whether they have been trained on community nursing position (all P<0.05). Conclusions The job satisfaction degree of community nurses is generally at middle level. Therefore, measures should be taken to improve the job satisfaction for the development of community nursing services.

Objective To study early diagnosis and treatment of Wernicke's encephalopathy(WE) in allogeneic peripheral blood stem cell transplantation recipients.Method A 17 years old patient with acute B-lymphocytic leukemia received HLA-matched nonrelative allogeneic peripheral blood stem cell transplantation after conditioning with total-body irradiation/idamycin/cyclophosphamide (TBI/IDA/Cy) regimen.CD25 monoclonal antibody and cyclosporine A+mycophenolate mofetil + methotrexate were administrated for graft versus host disease prophylaxis.Result On the day 8,the platelet was over 20 × 109/L; On the day 10,the neutrophile granulocyte was over 0.5 × 109/L; On the day 28,full engraftment was confirmed by a bone marrow medicolegal identification.The continued nausea and vomiting after HSCT resulted in deficiency of intake and malabsorption.On the day 54,illusion and tremor occurred,and the follow-up brain MRI suggested WE,but the patient died before thiamine replacing therapy.Conclusion WE is also a rare neurologic complication of HSCT,however,it can easily be overlooked.So early radiologic surveillance and treatment for patients with WE is very important to minimize central nervous system complications and unwanted mortality.

Objective To observe the effect of scalp nerve block ( SNB ) with ropivacaine hydrochloride at different time points on pain management after craniotomy. Methods Ninety patients undergoing craniotomy were randomly divided into 3 groups:group A, SNB conducted before surgery;group B, SNB conducted after surgery;group C, SNB conducted both before and after surgery, with 0. 5% of ropivacaine hydrochloride in each group. All patients received the same general anesthesia and diclofenac sodium were administered rectally as rescue analgesics. Sites and duration of surgeries, end-tidal sevoflurane concentration during incision, HR and SBP levels during the course of surgery and postoperative period, the VAS scores, GCS and Ramsay scores at 0. 5, 2, 4, 6, 12, 24, 48 h postoperatively, time of the first rescue appication analgesics and total consumption of rescue analgesics, the adverse effects, awareness under anesthesia were analyzed respectively, as well as local anesthesia relevant adverse events and time of wound healing. Results The end-tidal sevoflurane concentration was significantly decreased in group B (3. 19±0. 36)% as compared with group A (1. 81±0. 24)% and C (1. 77±0. 33)% (P<0. 05);The VAS scores of group A (3. 77±2. 27, 4. 20±2. 09) at 2 and 4 h were higher than those in group B (2. 77±1. 98, 3. 20±2. 20) and C (2. 97±1. 77,2. 27±1. 93) (P<0. 05), while at other time points the differences were not significant (P>0. 05);Compared with group A (600 mg), the consumption of rescue analgesics of group B (300 mg) and C (250 mg) were statistically lower (P<0. 05);Vital signs, GCS, Ramsay scores, time of the first rescue analgesics postoperatively used, and time of wound healing among the three groups were not various significantly (P>0. 05);The relevant side effects were not different statistically, and there were no patients suffering from obvious awareness under anesthesia, pruritus, respiratory depression or local anesthesia relevant adverse effects. Conclusion SNB conducted before surgery can decrease the consumption of sevoflurane during incision, but has limited analgesic effects postoperatively. SNB conducted after surgery may provide transitional analgesia for neurosurgical patients undergoing craniotomy, while SNB conducted both before and after surgery does not show significantly longer analgesic time in postoperative pain management.

OBJECTIVE:To systematically review the efficacy and safety of anti-vascular endothelial growth factor(VEGF)in-hibitors in the treatment of retinopathy of prematurity (ROP),and provide evidence-based reference for clinic. METHODS:Re-trieved from PubMed,EMBase,Cochrane Library,CJFD,VIP,CBM and Wangfang Database,randomized controlled trials (RCT) about VEGF inhibitors (test group) versus laser photocoagulation treatment (control group) in the treatment of ROP were collected. Meta-analysis was performed by using Rev Man 5.1 software after data extraction and quality evaluation by Cochrane re-viewers manual 5.1.0. RESULTS:Totally 5 RCTs were included,involving 381 infants and 754 eyes.Results of Meta-analysis showed that the recurrence rate of ROP [RR=0.23,95%CI(0.13,0.42),P<0.001],retinal detachment incidence [RR=0.27,95%CI(0.14,0.51),P<0.001] andresolution of plus signs [MD=-1.31,95%CI(-1.47,-1.14),P<0.001] in test group were signifi-cantly lower than control group,the differences were statistically significant;and there was no significant difference in the refrac-tive errors and the incidence of adverse reactions in 2 groups(P>0.05). CONCLUSIONS:Intravitreal VEGF inhibitors have better efficacy than laser photocoagulation in the treatment of ROP,but the optimal dose and safety need further verification by large-sam-ple and well-designed RCT.

Results Comparing with groupⅢ or T0, at T1 β-EP in the groupⅠwas gone up, while ACTH、 COR and VAS scores were lower in the groupⅠand groupⅡ; adverse circumstance in the groupⅠreduced than that in the groupⅡ. The VAS scores inThe groupⅠand groupⅡand Apgar score and NBNA assessment in three groups were not significantly different. Conclusion Combination of water acupuncture and remifentanil patient-controlled intravenous analgesia iseffec-tive. Ithas no adverse effects on mother and baby. It is an ideal method of labor analgesia.

Objective:To investigate the change of microalbuminuria (MA) in patients with RA and its clinical significance.Methods:From January 2018 to December 2019, data of 75 cases of RA patients were collected from outpatient and inpatient wardsof our hospital, and the data of 75 cases of physical examination wascollected as control. Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) anti-cyclic citrullinated peptide (CCP) antibody, blood lipid, Homeostasis model assessment for insulin resistance (HOMA-IR), rheumatoid factor (RF), anti-CCP antibodyand MA levels were measured respectively. RA patients were obtained by ultrasound Carotid intima-media thickness (cIMT) and brachial artery flow mediated diastolic function (FMD) were measured. The statistical analysis was carried out with independent t-test, analysis of variance, Pearson correlation analysis and multiple stepwise regression. Results:The MA level of RA patients was significantly higher than that of the healthy control group [(31±5) mg/L vs (25±4) mg/L, t=5.982, P<0.05]. In RA patients, MA level was positively correlated with course of disease ( r=0.327, P=0.015), HOMA-IR ( r=0.576, P<0.01], CRP ( r=0.212, P=0.027), RF ( r=0.585, P<0.01), disease activity score in 28 joints (DAS28) ( r=0.472, P=0.013), cIMT ( r=0.611, P<0.01) and duration of nonsteroidal anti-inflammatory drugs (NSAIDs) use ( r=0.274, P<0.01), and urineMA level( OR=1.763, P<0.01) were independent correlation factors affecting cIMT. Conclusion:The level of MA in RA patients is significantly higher than that in normal controls, and is correlated with disease activity and subclinical atherosclerosis, which could be another important predictor of disease follow-up and early screening of subclinical atherosclerosis in RA patients.

OBJECTIVE:To understand the main diseases research area and tendency of the literatures published on top-five global biomedicine journals,and provide reference for topics and designs of domestic medical research. METHODS:Studies pub-lished on NEJM,JAMA,BMJ,Lancet and PLoS Medicine from 2004 to 2013 were searched via Web of Science;types of disease were classified by using International Classification of Diseases(version 10)(ICD-10);research types were analyzed according to the rules in clinical epidemiology. RESULTS:Most of studies(25.8%)were published on BMJ;USA(39.1%),UK(25.7%) and Canada(5.1%)were top-three countries for the first authors;circulation system disease,infectious and parasitic diseases,can-cer,endocrine,nutritional and metabolic disease and respiratory system disease were top-five in disease categories list,accounting for 61.7%;ischemic heart disease,HIV-related disease,diabetes,other heart disease and influenza and pneumonia were the main top-five specific diseases;and randomized controlled trials were main study type. CONCLUSIONS:The proportion of the first au-thor for the Chinese literature in the host country is very low. Top-five specific diseases are placed on circulation system disease,in-fectious and parasitic diseases,endocrine,nutritional and metabolic disease and respiratory system disease,with the main study types of randomized controlled trial,cohort study and systematic review.

Objective To evaluate Mycobacterium tuberculosis (M. tuberculosis)-specific cellular immunity in individuals with latent or active tuberculosis and human immunodeficiency virus (HIV) coinfection. Methods One hundred HIV-infected individuals in Yunnan Province were enrolled. The enzyme-linked immunospot (ELISPOT) assay using early secreted antigenic target (ESAT)-6 and culture filtrate protein (CFP)-10 was employed to detect M. tuberculosis-specific T cells in the peripheral blood. The absolute number of CD3+ CD4+and CD3+ CD8+ T cells in the peripheral blood from the enrolled subjects were determined by flow cytometry. Data were analyzed using nonparametric Mann-Whitney test. Results The prevalence of latent tuberculosis co-infection in HIV-infected individuals without any clinical evidence of active tuberculosis was 67.6%. The absolute numbers of CD3+ CD4+ (532 × 106/L) and CD3+ CD8+ (473 × 106×/L) T cell in HIV-infected individuals with latent tuberculosis co-infection were similar to those of only HIV-infeeted individuals (406 ×106×/L and 504 × 106/L). While those in HIV-infected individuals with active tuberculosis co-infection were 189 × 106/L and 293 × 106/L, respectively, which were both significantly lower than those in other two groups (U=168. 0,U=163. 0,U= 374. 0,U=147. 0, all P<0. 01). Furthermore, ESAT-6 (31/106 cells) and CFP-10 (82/106 cells) specific spot-forming cells in HIV-infected individuals with active tuberculosis co-infection were significantly less than those in HIV-infected individuals with latent tuberculosis co-infection (92 × 106 cells and 109 × 106 cells, U= 507. 0,U= 529. 5, both P<0. 01). Conclusions The prevalence of latent tuberculosis in HIV-positive individuals without any clinical evidence of active tuberculosis is high in China. Both overall cellular immunity and M. tuberculosis-specific immune response in HIV-positive individuals with active tuberculosis co-infection are severely impaired.
