Objective To explore the drug resistance of Pseudomonas aeruginosa in patients with severe respiratory disease and environment, and to conduct molecular epidemiological investigations on it. Methods The strains of Pseudomonas aeruginosa isolated from patients with severe respiratory disease and the environment in a hospital in Xi'an from 2020 to 2022 were collected for drug sensitivity test and drug resistance gene detection, and the homology of Pseudomonas aeruginosa strains was analyzed by using multiple site sequence typing （MLST） and pulsed field gel electrophoresis （PFGE）. Results A total of 994 strains of Pseudomonas aeruginosa were collected, of which 668 strains were from patients, accounting for 67.20%, and 326 strains （32.80%） were from environmental samples. The drug sensitivity test showed that the resistance rates to amitriptyline and piperacillin were the highest, exceeding 30%; Next were imipenem （28.37%） and meropenem （29.18%）, with resistance rates to piperacillin/tazobactam, ciprofloxacin, levofloxacin, ceftazidime, cefepime, and cefoperazone/sulbactam all ranging from 20% to 30%. The resistance rates to aminoglycoside antibiotics and lipopeptides were below 20%, with polymyxin B （1.51%） being the lowest. The sequencing results of resistance genes showed that the positive rate of OprD2 gene was the highest, at 33.60%; Next were aminoglycoside modifying enzymes aac （6’）-Ib （28.97%） and ant （3"）-I （27.16%）, as well as the carbapenem enzyme gene bla_IMP （22.64%） and ESBLs gene bla_TEM （19.52%）. Thirty‐one STs types were classified by MLST, mainly ST235 （38.53%）, ST244 （31.09%）, and ST298 （12.68%）. The PFGE typing result identified a total of 16 subtypes from A to Q, with type A （34.21%） and type C （21.33%） being the main subtypes. Conclusions Drug resistance of Pseudomonas aeruginosa strains is common in patients with severe respiratory disease, with ST235 and ST244 being the main prevalent clones in the local area. Targeted strengthening of hospital infection monitoring for patients with severe respiratory disease and cleaning of the intensive care unit is beneficial for controlling the spread and prevalence of Pseudomonas aeruginosa.

Objective To investigate the status of workplace violence suffered by nursing staff in Xinjiang and analyze the influencing factors. Methods Using the “National Case Study Tool on Workplace Violence in Health Institutions‐Questionnaire”, a survey was conducted among 1 600 nursing staff from 16 medical and health institutions in 4 administrative regions of Xinjiang. The binary logistic regression model was used to analyze the influencing factors of workplace violence suffered by nursing staff. Results The incidence of workplace violence among nursing staff in Xinjiang was 68.69%, of which 8.94% had suffered physical violence and 59.75% had suffered psychological violence. When suffering from physical violence and psychological violence, the highest proportion of disposal methods were informing managers （17.52%） and complaining to colleagues （22.07%）, and the lowest proportion were solving through legal means （2.31%） and seeking help from unions or associations （2.48%）. Multivariate logistic regression analysis showed that the nursing staff of Han nationality （OR=1.696）, outpatient and emergency department （OR=5.936）, chief nurse and above （OR=5.980）, tertiary hospitals （OR=9.391）, college degree or below （OR=8.830）, and those with more night shifts per month （OR=3.915） were at higher risk of workplace violence. Conclusions The incidence of workplace violence suffered by nursing staff in Xinjiang is relatively high, and most of the experiencers are still limited to the personal level and are not satisfied with the disposal outcome. The occurrence of workplace violence is related to hospital level, department, night shift, administrative position, educational background, and so on.

Objective To explore the effects of different exercise modes on improving exercise endurance and myocardial function in patients with essential hypertension. Methods A total of 180 patients with essential hypertension were selected from a certain hospital of the Chinese PLA General Hospital from June 2020 to December 2022. According to the method of random number table, the patients were divided into three groups： high‐intensity intermittent aerobic exercise training group （AIT group）, moderate to low intensity continuous aerobic exercise training group （MIT group）, and quiet control group （Control group） without exercise training, with 60 cases in each group. The exercise training lasted for 12 weeks in the exercise intervention group. Blood pressure, heart rate （HR）, body mass index （BMI）, echocardiogram, and exercise endurance were compared before and after exercise intervention. Results Among 180 patients, there were 119 males and 61 females, aged 35-87 years old, with an average of （52.83±5.12） years old. The BMI was 18.2-36.9 kg/m², with an average of （24.74±2.32） kg/m². The course of the disease was （4.96±0.98） years. Hypertension classification： 54 cases at grade I, 79 cases at grade Ⅱ, and 47 cases at grade Ⅲ. There were 116 cases with good medication adherence and 64 cases with poor medication adherence. There were no statistically significant differences in gender distribution, age, course of disease, BMI, HR, SBP, DBP,blood pressure grading, and medication adherence among the three groups of patients （all P>0.05）. There were no statistically significant differences in SBP, DBP, HR, echocardiography indicators, and exercise endurance indicators among the three groups of patients before exercise intervention （all P>0.05）. The differences in SBP, DBP, HR, left ventricular mass index （LVMI）, left ventricular end diastolic diameter （LVDD）, left ventricular posterior wall thickness （LVPWT）, interventricular septal thickness （IVST）, maximum oxygen consumption （VO₂）, and metabolic equivalents （METs） among the three groups of patients after exercise intervention and before and after intervention were statistically significant （all P<0.01）. Conclusions The antihypertensive effect of exercise is intensity dependent in patients with essential hypertension. Compared with moderate to low intensity continuous aerobic exercise, high‐intensity intermittent aerobic exercise has a better improvement effect and is an effective way to reduce blood pressure and improve other cardiovascular risk factors.
