Objective To find a simple and effective way for pericardial effusion.Methods Arterial sheath were applied to patients with pericardial effusion when pericardium puncture were performed,and negative pressure drainage bag were connected and aspirated interruptively to no aspiration.1～2 days later,arterial sheath were drawn out.Results 40 cases of pericardial effusion were effectively cured by this method,and clinical effective rate was 100%,and no complication associated with arterial sheath placement was observed.Conclusion Arterial sheath placement is an effective,safe and convenient method for the treatment for pericardial effusion.This method can be routinely applied to pericardial effusion due to different causes.

Objective To investigate blood pressure and blood lipids change in official staff population. Methods Official staffs were divided into normal blood pressure group, pre-hypertension group, hypertension group and hypertension under control group based on their blood pressure, and hypertension incidence in pre-hypertension group,hypertension group were studied, hypertension incidence in pre-hypertension group and normal blood pressure group were compared; all staff were divided into normal blood lipids group and high blood lipids group based on their blood lipids. Results Hypertension incidence of official staffs was increasing year by year; hypertension incidence of pre-hypertension group was apparently higher than that of normal blood pressure group (P < 0.01) ; the incidence of hypertension in high blood lipids group(total cholesterol and triglyceride) was apparently higher than that of normal blood lipids group(P < 0.05). Conclusion Life style intervention should be performed on official staffs, especially for pre-hypertension group, blood pressure and blood lipids tracing should be applied on them,in order to decrease the incidence of hypertension and cardiac and cerebral vascular stroke.

Objective:To observe the effects of rolling manipulation with different durations on erector spinae muscle tonus and low back pain in patients with lumbar muscle strain and to explore the best duration for rolling manipulation in treating lumbar muscle strain. Methods:A total of 75 patients who met the inclusion criteria were randomized into a 5-minute rolling manipulation group,a 10-minute rolling manipulation group,and a 15-minute rolling manipulation group using the random number table method,with 25 cases in each group.All three groups were treated with the same rolling manipulation,while the treatment time was 5 min,10 min,and 15 min,respectively.The treatment was performed 3 times a week for 2 consecutive weeks.The muscle tonus of bilateral erector spinae and visual analog scale(VAS)score for low back pain were compared among the three groups before and after treatment. Results:A total of 63 patients completed the study.Before treatment and after the last treatment,there were no statistical differences in the muscle tonus of the left erector spinae and right erector spinae among the three groups(P>0.05).After the last treatment,bilateral erector spinae muscle tonus dropped compared with the baseline in all three groups(P<0.01).Before treatment and after the last treatment,there were no significant differences in comparing the low back pain VAS score among the three groups(P>0.05).After the last treatment,the VAS score for low back pain in all three groups decreased(P<0.01). Conclusion:Under the condition that the forward swing force is 50-70 N,the backward swing force is 20-40 N,and the frequency is 138 times/min,the 5-minute rolling manipulation can significantly reduce the muscle tonus of erector spinae and relieve low back pain.

Objective To explore the effect of core self-evaluation on turnover intention of clinical specialized nurses and provide reference for nursing administrators.Methods A total of 220 nurses from Ji'nan City,Shandong Province were selected to conduct a questionnaire survey from April to June 2016. The general nurses' general questionnaire,core self-evaluation scale and turnover intention scale were used to investigate. Results The total score of core self-evaluation of clinical specialized nurses was (36.42±5.86),and the total score of nurse's turnover intention was (15.66±3.48). Age,job title,education background and core self-evaluation had predictions of turnover intention for the nurses.Conclusions Nursing managers should take measures to improve the core self-evaluation of specialist nurses in order to reduce their turnover rate and stabilize the nursing team.

Objective To observe the incidence of adverse reactions and short-term efficacy of S-1 and concurrent intensity-modulated radiotherapy ( IMRT) for locally advanced gastric cancer in a phase Ⅱclinical trial based on the phase I clinical trial.Methods Patients pathologically diagnosed with stage TN (+) gastric adenocarcinoma with local or distal metastasis after R0 resection were enrolled as subjects.IMRT was delivered 5 times per week with a total dose of 45 Gy in 25 fractions.S-1 was orally administered on the day of radiotherapy at a dose of 80 mg/m2 .Results A total of 40 patients, consisting of 6 patients from the phase I trial and 34 patients from the phaseⅡtrial, were enrolled in this study.In those patients, the age ranged between 27 and 73 years ( median age 50 years) and the male-to-female ratio was 3:1.Thirty-nine ( 98%) out of the forty patients completed radiotherapy and thirty-five ( 88%) completed concurrent chemotherapy.The most common grade 3-4 adverse reactions were nausea/anorexia ( 13%) , leukopenia ( 10%) , vomiting ( 8%) , radiation esophagitis ( 5%) , and neutropenia ( 5%) .There was no perioperative death.The 2-year overall survival and disease-free survival rates were 74% and 77%, respectively. Conclusions Postoperative S-1 and concurrent IMRT achieve satisfactory outcomes and tolerable toxicity in patients with locally advanced gastric cancer.

Objective To evaluate the range of motion of gastroesophageal junction (GEJ) adenocarcinoma during preoperative radiotherapy.Methods Fourteen consecutive patients who received preoperative chemoradiotherapy for GEJ adenocarcinoma were included in this study.Fiducial markers were placed on the upper and lower edges of and around the primary tumor under a gastroscope.Eight patients underwent four-dimensional computed tomography to obtain 98 intrafractional images containing 8 fiducial markers at the GEJ.Twelve patients underwent cone-beam computed tomography at the 1 st to 5th,7th,12th,17th,and 22nd courses of radiotherapy to obtain 90 interfractional images.The paired t test was used for difference analysis.Results The intrafractional tumor displacements in left-right (LR),ventro-dorsal (VD),and cranio-caudal (CC) directions were 0.92±0.95 mm,2.27±2.73 mm,and 9.95±5.48 mm,respectively;the motion in CC direction was larger than that in LR or VD direction (P=0.000 or P=0.000);the motion in VD direction was larger than that in LR direction (P=0.000).The interfractional tumor displacements in LR,VD,and CC were 6.56±4.19 mm,5.69±3.29 mm,and 6.49±4.37 mm,respectively;the motion in LR or CC direction was larger than that in VD direction (P=0.031 or P=0.044);there was no significant difference between the motions in LR and CC directions (P=0.956).In order to ensure 95% of prescribed dose to at least 90% of the tumor volume,the margins from GEJ lesion in LR,VD,and CC directions were 19.4 mm,14.6 mm,and 27.2 mm,respectively,which could cover both intrafractional and interfractional tumor displacements during preoperative radiotherapy.Conclusions GEJ tumor has a wide range of movement in preoperative intra-and inter-fractional radiotherapy.This should be considered for precise radiotherapy,and a new method should be selected to limit tumor movement.

Sleep is essential for the maintenance of human normal functions.Nowadays,the occurrence of active sleep deprivation(ASD)or passive sleep depriva-tion(PSD)is becoming more and more common due to the inability of the body adapting to the rapid changes in the internal and external environment.SD is not only an action,a brief process or a result,but also a directly or indirectly sustained state,which is associated to sleep time,circadian rhythm or sleep quality.SD can lead to numerous adverse effects on the body,such as sleep-related acute and chronic diseases.Long-term SD increases the risk of neurological and cardiovascular dis-eases as well as immune system dysfunction.In addi-tion,SD may affect the reproductive health of the body,giving rise to a series of potential fertility problems.In recent years,the correlation research and mechanism between SD and the related diseases have become a focus of scholars' attention.Numerous lines of evidence suggest that pathological sleep,such as insomnia and sleep apnea syndrome,is associated with impaired repro-ductive function.Disruptions in the circadian rhythm can also lead to impaired hypothalamic-pituitary-gonadal(HPG)axis function and thereby interfere with the repro-ductive process.Our research team has demonstrated that SD significantly affects the fertility of male and female rats and has adverse effects on reproduction.By new generation sequencing(NGS)and RT-PCR verifica-tion,we have identified differently expressed genes that are involved in mediating the effect of SD on fertility.However,the mechanisms and biological macromolecules regulated by SD are worthy of being further explored.This paper provides a brief review of SD research and then focuses on the adverse impact of SD on fertility,conducting a literature review to sort out the ideas and pro-vide references for research in this field.

Objective To retrospectively analyze the long-term efficacy of and prognostic factors after preoperative chemoradiotherapy combined with total mesorectal excision (TME) in the treatment of 241 patients with locally advanced rectal cancer.Methods A total of 241 patients who were consecutively admitted to our hospital and diagnosed with locally advanced mid-low rectal adenocarcinoma by pelvic magnetic resonance imaging or computed tomography from January 2006 to November 2014 were enrolled as subjects.All patients received preoperative radiotherapy with doses ranging between 42.0 and 50.4 Gy (median dose =50 Gy) and concurrent chemotherapy with capecitabine ±oxaliplatin.Patients received TME (R0 excision) at 4-15 weeks (median time =7 weeks) after chemoradiotherapy.Adjuvant postoperative chemotherapy was given depending on the recovery and preference of each patient.Disease-free survival (DFS),locoregional recurrence (LRR),overall survival (OS),and distant metastasis (DM) rates were calculated by the Kaplan-Meier method and analyzed by the log-rank test.The Cox model was used for multivariate analysis.Results In all the patients,the median follow-up time was 42 months;the 3-year LRR,DFS,OS,and DM rates were 3.8％,76.2％,85.9％,and 20.6％,respectively.The subgroup analysis showed that ypT0-2,ypN-,pCR,and TRG4 were associated with improved DFS (ypT0-2 vs.yp T3-4:86.0％ vs.69.3％,P =0.002;ypN-vs ypN +:88.1％ vs.56.9％,P=0.000;pCR vs.non-pCR:100％ vs.72.4％,P=0.001;TRG4 vs.TR G2-3 vs.TR G0-1:94.9％ vs.73.6％ vs.66.3％,P=0.011).The multivariate analysis revealed that the postoperative ypN status was an independent prognostic factor for DFS (P=0.000).Conclusions For patients with locally advanced mid-low rectal adenocarcinoma,preoperative chemoradiotherapy combined with radical surgery achieves satisfactory outcomes in local control.The major reason for treatment failure lies in distant metastasis.The ypN status after chemoradiotherapy is an independent prognostic factor for DFS.

Objective:To investigate the relevant situation of the emergency departments (ED) of general hospitals at all levels in Zhejiang Province participating in the prevention and control of Corona Virus Disease 2019 (COVID-19), and to provide a reference for further improving the capacity of emergency services.Methods:A multi-center cross-sectional investigation study was jointly initiated by the Zhejiang Provincial Emergency Medicine Quality Control Center, the Emergency Medicine Branch of Zhejiang Medical Association, and the Emergency Physicians Branch of Zhejiang Medical Doctors Association. Before investigation, experts were organized to develop a special questionnaire. Then the ED of general people's hospitals or Chinese Medicine hospitals at the county/district-level or above were included and their participations in the prevention and control of COVID-19 epidemic between March 9, 2020 and March 15, 2020 were investigated. The collected information included: basic information of the hospitals; participation of ED in fever clinics; the number of COVID-19 patients admitted to ED; the situation of ED support to the anti-epidemic front-line; and the epidemic prevention facilities of ED, and the early supply of medical protective equipments.Results:A total of 181 hospitals from 11 prefectures and cities across the province were finally included, including 52 (28.7%) Grade-A tertiary hospitals, 45 (24.9%) Grade-B tertiary hospitals, 64(35.4%) Grade-A secondary hospitals, and 20 (11.0%) Grade-B secondary or lower hospitals. Among them, 93 (51.4%) were COVID-19 designated hospitals, and 49 (27.1%) had the ability to detect COVID-19 nucleic acid; 177 (97.8%) set up independent fever clinics and 33 (18.6%) were managed by ED alone or mainly. The medical staffs of 65 (36.7%) fever clinics were all or mainly from ED. A total of 213 cases of COVID-19 were received/treated in 40.3% ED, accounting for 17.3% of the total number of cases in Zhejiang Province. A total of 3 848 doctors and nurses supported the front-line of epidemic prevention, of them, 253 supported Hubei Province (accounting for 12.5% ??of the total number). There were 68.5% and 76.8% ED having spare separate clinic and ordinary rescue single room to deal with the COVID-19. In addition, at the early days of anti-epidemic, more than 50% ED were in short supply or even had no medical protective equipment.Conclusions:The ED of Zhejiang Province plays an important role and has made a great contribution to the prevention and control of the COVID-19 epidemic. It is necessary to improve the conditions of ED to effectively respond to the prevention and control of daily infectious diseases.

Inflammatory bowel disease (IBD) is characterized by recurrent non ⁃ specific intestinal inflammatory responses. Intestinal fibrosis is an important cause of IBD complicated with intestinal obstruction. Nuclear factor erythroid 2⁃ related factor 2 (Nrf2) is a transcription factor that has anti ⁃ oxidative stress response in cells. In IBD, Nrf2 and its downstream regulated antioxidant enzymes achieve protective effects against intestinal fibrosis by inhibiting the activation of nuclear factor ⁃ κB, regulating T helper cell 17/regulatory T cell balance of intestinal immunity, and inhibiting transforming growth factor⁃β1/Smads signaling pathway. In this review, the structure of Nrf2, the specific mechanism of Nrf2's effect on intestinal fibrosis in IBD, and the recent studies on the treatment of IBD through Nrf2 pathway were reviewed in an attempt to provide a new direction for the prevention and treatment of IBD.
