Compared to traditional suturing, lung stapling using automatic staplers offers advantages such as smaller trauma, faster wound healing, ease of operation, and lower complication rates, making it widely used in clinical practice. However, there are significant differences in bronchial tissue thickness at different anatomical locations, and the market is flooded with various types of staplers. Currently, there is a lack of recommended stapling schemes for bronchial staplers at different anatomical locations. This article reviews the development and application of automatic staplers and summarizes some types of staplers that are currently used in clinical practice, with the aim of promoting the formation of individualized stapler selection protocols for minimally invasive thoracic surgery based on the Chinese population.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To observe the effect of abdominal acupuncture in treating allergic rhinitis(AR).Methods Twenty-seven AR patients who attended Fangshan Hospital,Beijing University of Chinese Medicine from August to October 2022 were selected.They were divided into treatment group(15 cases)and control group(12 cases)according to randomized numerical table method.The treatment group received abdominal acupuncture.The control group at the same point was used one-time sterile cannula acupuncture to simulate acupuncture,but no needle was inserted into the acupoint.Two groups were treated,3 times a week for 4 weeks.The visual analogue scale(VAS),rhinoconjunctivitis quality of life questionnaire(RQLQ),Pittsburgh sleep quality index(PSQI)scores,and the histamine(HIS),leukotriene D4(LTD4),immunoglobulin E(IgE)levels were compared between two groups before and after treatment.Results At each time point after treatment,the VAS,RQLQ,PSQI scores and HIS,LTD4,IgE levels of patients in treatment group were significantly lower than those before treatment(P<0.05).There were no statistically significant differences in VAS,RQLQ,and PSQI scores,the HIS,LTD4,and IgE levels after 2-week treatment in both groups(P>0.05).After 4-week treatment and follow-up 4-week,the VAS,RQLQ,and PSQI scores,the HIS,and LTD4 levels in treatment group were significantly lower than those in control group(P<0.05).Conclusion Abdominal acupuncture has good therapeutic effect on AR and significantly improves life quality of the patients,which can reduce the levels of HIS,LTD4 and IgE.The therapy is worthy of clinical application.

Objective:To observe multiple locus variable-number tandem repeat analysis (MLVA) typing of Brucella isolated from Himalayan marmot in Qinghai-Tibet Plateau of Qinghai Province, and to explore the relationship between the strains and strains previous isolated from Qinghai Province. Methods:Blood samples of Himalayan marmot were collected in Qinghai-Tibet Plateau of Qinghai Province from March 2019 to October 2020. Pathogens were isolated and cultured from Brucella antibody positive samples identified by using the rose bengal test (RBT). Conventional biological methods and molecular biological methods (BCSP31-PCR and AMOS-PCR) were used for strain identification. At the same time, MLVA method was used to genotype the isolated strains, and cluster analysis was used to analyze the genetic relationships between the strains based on the genotype of 70 Brucella isolated from different hosts in Qinghai Province. Results:A total of 1 466 blood samples of Himalayan marmot were collected from Qinghai-Tibet Plateau. Two strains of Brucella were isolated and cultured from 64 RBT-positive samples, named QH2013054 and QH2013062, respectively. They were identified as Brucella ovis biotype Ⅲ by conventional and molecular biological methods. The MLVA genotyping results showed that QH2013054 and QH2013062 were different at the Bru16 locus, indicating different MLVA genotypes. Cluster analysis showed that strain QH2013054 had the same MLVA genotype as 7 strains, among which 6 strains were from 3 farmers and 3 sheep from the same family in Gonghe County, and 1 strain was from a farmer in Menyuan Hui Autonomous County. The strain QH2013062 had the same MLVA genotype as 4 strains, including 3 strains from 3 farmers in Menyuan Hui Autonomous County and 1 strain from a farmer in Tu Autonomous County of Huzhu. Conclusions:The strains of Brucella isolated from Himalayan marmot in Qinghai-Tibet Plateau of Qinghai Province have the same MLVA genotype as some strains of Brucella isolated from humans and sheep in Qinghai Province. It is speculated that the host humans, sheep and Himalayan marmot in Qinghai-Tibet Plateau may have a common source of infection.

Objective:To learn about the epidemic situation and trend of human brucellosis in Menyuan Hui Autonomous County (referred to as Menyuan County) of Qinghai Province, and to provide reference for formulating brucellosis prevention and control measures in Menyuan County.Methods:Data on human brucellosis in Menyuan County reported by the Infectious Disease Reporting Information Management System of China Disease Control and Prevention Information System from 2013 to 2020 were collected and analyzed by descriptive epidemiological analysis (three distribution).Results:A total of 186 cases of brucellosis were confirmed from 2013 to 2020, with an average annual incidence of 14.553/100 000. The annual incidence rate was increasing year by year(χ 2trend = 22.08, P = 0.002). The cases were distributed in 67 villages of 12 towns; cases were more common in the age group of 15-< 65 years old (96.24%, 179/186), and there were more men than women cases (sex ratio was 3.89∶1.00, 148/38). Conclusions:The incidence rate of brucellosis cases in Menyuan County is increasing year by year, and the scope of its impact is constantly expanding. A multi-sectoral joint prevention and control mechanism should be established to strengthen management, increase the prevention and control of brucellosis, and stop the spread of the epidemic to surrounding counties and cities.

Objective: To investigate the health-related quality of life and its influencing factors among urban adults in Hangzhou City, so as to provide the evidence for formulation and assessment of health policy. Methods: A total of 1 800 permanent residents at ages of 18 to 64 years were sampled from Gongshu and Xihu districts, Hangzhou City using a stratified cluster random sampling method from May to August 2022. The health-related quality of life was measured with the EuroQol five-dimensional questionnaire (EQ-5D-5L), and factors affecting health-related quality of life were identified with a Tobit regression model. Results: A total of 1 624 valid questionnaires were recovered, with a response rate of 90.22%, and the respondents included 693 men (42.67%) and 931 women (57.33%). The proportions of difficulty in mobility, self-care, usual activities, pain/discomfort, and anxiety/depression were 1.23%, 0.43%, 0.74%, 11.15% and 8.56%, and the median (interquartile range) of health state utility value and EuroQol Visual Analogue Scale (EQ-VAS) score were 1 (0) and 90 (15) points, respectively. Female (β=-0.050), age of 45 to 64 years (β=-0.067) and development of chronic disease (one chronic disease: β=-0.036; two and more chronic diseases: β=-0.090) were factor affecting of health state utility values, and age of 35 to 44 years (β=-1.945) and 45 to 64 years (β=-3.459), unemployment (β=-1.913), development of chronic disease (one chronic disease: β=-3.444; two and more chronic diseases: β=-8.529), high-level physical activity (β=2.355) and overweight/obesity (β=-1.456) were factors affecting the EQ-VAS score. Conclusions The overall health related quality of life is relatively good among urban adults in Hangzhou City. Gender, age, employment, physical activity, presence of chronic diseases and overweight/obesity may be associated with health-related quality of life among urban adults in Hangzhou City.

Objective:To explore the association between internet use and healthy lifestyles in urban adults.Methods:From May to August, 2022, a face-to-face questionnaire survey was conducted in residents aged 18-64 years selected in the urban area of Hangzhou by integrated cluster stratified random sampling and Kish grid method. The information about internet use included the internet use time in the past 7 days and 12 kinds of internet use contents. Using factor analysis and K-means clustering, three types of internet use were summarized, i.e. general type, video game type and working/learning type. Healthy lifestyles were defined as active physical activity, healthy diet habit, non-smoking, non-drinking, healthy weight, and healthy waist circumference. The correlations between internet use and healthy lifestyles were evaluated by using binary logistic regression and multinomial logistic regression analyses.Results:A total of 1 624 participants were included. After adjusting for potential confounding factors, the longer internet use time group (≥8.5 h/d) was less likely to have healthy weight ( OR=0.59, 95% CI:0.41-0.85) and 5-6 healthy lifestyles ( OR=0.55, 95% CI: 0.32-0.96) compared with those with shorter internet use time group (<2.5 h/d). For different types of internet use, it was found that compared with working/learning type group, the general type group was less likely to have healthy diet habits ( OR=0.63, 95% CI: 0.46-0.86), non-drinking ( OR=0.68, 95% CI: 0.47-0.99), healthy waist circumference ( OR=0.59, 95% CI: 0.42-0.84) and 5-6 healthy lifestyles ( OR=0.40, 95% CI: 0.23-0.69), the video game type group was less likely to have active physical activity ( OR=0.73, 95% CI: 0.55-0.97) and healthy diet habits ( OR=0.79, 95% CI: 0.62-0.99). Conclusion:Too long internet use (≥8.5 h/d), general type and video game type of internet use were associated with unhealthy lifestyles.

Objective:To explore the influence of nursing organization atmosphere on clinical nurses' workplace loneliness, verify and analyze the mediating role of psychological capital between nursing organization atmosphere and workplace loneliness.Methods:This study was a cross-sectional survey, using the convenience sampling to select clinical nurses from two Class Ⅲ Grade A hospitals in Shanxi Province from October to December 2019 as the research object. The survey was conducted using the General Information Questionnaire, Organizational Climate Scale for Nursing, Questionnaire about Workplace Loneliness, and Psychological Capital Scale. The structural equation model was used to analyze the mediating effect of psychological capital between nursing organization atmosphere and workplace loneliness. A total of 1 035 questionnaires were collected in this study, with 963 valid questionnaires, and the effective response rate was 93.04%.Results:Among 963 clinical nurses, the total scores of Organizational Climate Scale for Nursing, Questionnaire about Workplace Loneliness, and Psychological Capital Scale were (88.08±10.08) , (30.42±5.23) and (83.21±12.62) respectively. The structural equation model showed that the nursing organization atmosphere had a direct and indirect predictive effect on nurses' workplace loneliness, and the path coefficients were -0.27 and -0.22 respectively. Psychological capital had a mediating effect between the nursing organization atmosphere and workplace loneliness.Conclusions:Psychological capital plays a mediating role between nursing organization atmosphere and workplace loneliness. Nursing managers should take effective measures to create a good organizational atmosphere, improve the level of psychological capital of clinical nurses, and reduce nurses' workplace loneliness.

Objective:To explore the effect of team positive psychological intervention on psychological state and coping style of nurses after being impacted by life events.Methods:From September 2020 to January 2021, 84 nurses who had suffered life events in Shanxi Provincial People's Hospital were selected by the convenient sampling method. According to the enrollment time, they were divided into the experimental group ( n=42) and the control group ( n=42) . The nurses in the control group were not give external intervention measures, while nurses in the experimental group adopted team positive psychological intervention. After 6 weeks of intervention, the Chinese version of Psychological Resilience Scale, Symptom Checklist 90 (SCL-90) and Simple Coping Style Questionnaire were used to compare changes in the psychological resilience level, mental health level and coping style of nurses in the two groups. Results:After intervention, the scores of toughness, strength and optimism dimensions and the total scores of Psychological Resilience Scale in the experimental group were significantly higher than those in the control group, and the differences were statistically significant ( P<0.05) . The total score of SCL-90 in the experimental group was significantly lower than that in the control group, and the difference was statistically significant ( P<0.05) . The score of positive coping dimension of nurses in experimental group was significantly higher than that in control group, and the score of negative coping dimension was significantly lower than that in control group, and the differences were statistically significant ( P<0.05) . Conclusions:Team positive psychological intervention can improve psychological resilience and mental health level of nurses who are impacted by life events. At the same time, it can also encourage them to adopt active coping methods to face problems, which is conducive to improving quality of nursing.
