The rapid development of minimally invasive surgery in thoracic surgery has significant advantages over traditional surgery.At the same time, problems such as the difficulty in obtaining specimens from small incisions and the increase in operating costs due to special medical consumables have also emerged. Therefore, how to remove surgical specimens safely, efficiently and cost-effectively is an important issue faced by thoracic surgeons during surgery. Operating room sterile gloves are often used as specimen collection bags and widely used in thoracic surgery and many other departments because of their easy availability, low cost, and good flexibility. At present, most of the glove specimen collection bags are based on sterile gloves, and various manufacturing methods have evolved by the combination with instruments and sutures.This article will briefly review the application of various forms of glove specimen retrieval bags in thoracoscopic surgery reported in existing research, analyze their advantages, disadvantages and scope of application, so as to provide references for future clinical applications and technological innovation researches.

Objective To comprehensively analyze the effectiveness of exercise training-based respiratory rehabilitation therapy on patients with occupational pneumoconiosis (hereinafter referred to as "pneumoconiosis"). MethodsLiterature on randomized controlled trials of exercise training-based respiratory rehabilitation therapy for pneumoconiosis patients published from the establishment of the database to July 2023 was retrieved from academic systems such as the China National Knowledge Infrastructure, Wanfang Data Knowledge Service Platform, VIP Database, and China Biology Medicine using bibliometrics method. The RevMan 5.4 software was used for meta-analysis of the selected literatures. Subgroup analysis was conducted to explore the source of study heterogeneity. The funnel plot method was used to test publication bias. Results A total of 55 articles were included, involving 2 436 pneumoconiosis patients in the experimental group and 2 405 pneumoconiosis patients in the control group. The result of random or fixed effect model showed that the six minutes walking distance, the total score of Short from Health Survey-36, forced vital capacity (FVC), forced expiratory volume in one second (FEV₁), FEV₁/FVC, arterial partial pressure of oxygen of pneumoconiosis patients increased after respiratory rehabilitation therapy (all P<0.05), while the total score of the St. George's Respiratory Questionnaire and arterial partial pressure of carbon dioxide decreased compared with the conventional treatment (all P<0.05). The result of subgroup analysis showed that the total score of the St. George's Respiratory Questionnaire, FEV₁, and the index of arterial partial pressure of oxygen of pneumoconiosis patients was better in the rehabilitation treatment for ≥six months compared with those

Objective:To understand the prevalence of insufficient physical activity among adults aged ≥18 years in China and to explore the influencing factors.Methods:The China Chronic Disease and Risk Factor Surveillance was conducted in 298 counties/districts in China in 2018, covering 31 provinces (autonomous regions, municipalities). A multi-stage stratified cluster random sampling method was used to select permanent residents aged ≥18 years. A questionnaire including Global Physical Activity Questionnaire was used to collect information about the participants' demographic characteristics and physical activity through face-to-face interview. A total of 183 769 participants completed the survey. After complex data weighting, the prevalence of insufficient physical activity, occupation, transportation, and leisure-time physical activity time was analyzed. Multivariate logistic regression models were used to analyze the influencing factors related to insufficient physical activity.Results:The prevalence of insufficient physical activity among adults aged ≥18 years was 22.3% (95% CI: 20.9%-23.7%) in China in 2018, with males [24.4% (95% CI: 23.0%-25.8%)] significantly higher than females [20.2% (95% CI: 18.6%-21.8%)]. Adults aged 70 years and above [28.4% (95% CI: 26.9%-29.9%)] were significantly higher than adults in other age groups, followed by adults aged 18-29 years [26.4% (95% CI: 24.4%- 28.3%)] and 30-39 years [23.4% (95% CI: 21.5%-25.3%)], and tended to increase with increasing education and total sedentary behavior time ( P<0.001). The weekly occupation, transportation, and leisure-time physical activity time appeared 958.6 (95% CI: 911.4-1 005.8) minutes, 234.5 (95% CI: 224.7- 244.2) minutes, and 88.6 (95% CI: 83.5-93.7) minutes, respectively. Multivariate logistic regression analysis showed that males, adults living in rural areas or northern China, ≥70 years, with junior high school education, an annual household income per capita <6 000 yuan and institutional/clerical/ technical occupation and longer total sedentary behavior time were related to a higher prevalence of insufficient physical activity. Conclusions:In China, over one-fifth of the adults had lower physical activity levels. Adults who are male, young adults, more educated, institutional/clerical/technical occupation, and with more extended total sedentary behavior are the populations that need to be focused on to promote physical activity-related health.

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.

BACKGROUND: With the extensive development of minimally invasive surgery for pulmonary nodules, preoperative localization becomes more and more critical. There are some defects in traditional localization methods, so it is necessary to improve. The aim of this study was to compare and analyze the safety and effectiveness of two new methods, namely four-hook needle and memory alloy coil, in the localization of pulmonary nodules. METHODS: A retrospective analysis of 152 patients was performed. 76 cases were in four-hook needle group, and 76 cases were in memory alloy coil group. Pulmonary nodules were located before operation, and then video-assisted wedge resection was performed. The average procedure time, localization complications and nodule resection time were counted. RESULTS: The target pulmonary nodules were successfully removed in both groups. In four-hook needle group, 76 patients found localization devices, all the pulmonary nodules were successfully removed, and one case was transferred to open the chest for wedge resection of pulmonary nodules due to severe thoracic adhesion. All 76 patients in memory alloy coil group were successfully resected with pulmonary nodules, and one patient underwent compromising enlarged resection because no lesion was found after the specimen was removed during the operation. There was no significant difference in the incidence of pneumothorax and pulmonary hemorrhage, the success rate of localization and nodule wedge resection time between the two groups. The average time of localization in four-hook needle group was (13.66±3.11) min, lower than that of memory alloy coil group (15.51±3.65) min, and the difference was statistically significant (P=0.001). In memory alloy coil group, when the distance from the nodule to the pleura was ≥1.5 cm and <1.5 cm, the average localization time was (17.20±4.46) min and (14.91±3.15) min, respectively, and there was a statistical difference between the two distance (P=0.044). CONCLUSIONS Four-hook needle and memory alloy coil have good safety and effectiveness, and the localization time of four-hook needle is shorter. When using memory alloy coil, the effect of the method is better for pulmonary nodules with a distance less than 1.5 cm to pleura.

Objective : To explore the epicardial adipose tissue ( EAT) of patients with coronary heart disease , KLF7 stimulates macrophages to secrete inflammatory factors and promotes the differentiation and maturation of adipocytes through the NF⁃κB signaling pathway , and to clarify the mechanism of KLF7 in the occurrence and development of CAD. Methods : 30 patients with coronary heart disease ( CAD group) and 30 patients without coronary heart disease (non⁃CAD group) were collected , and general data and biochemical indicators were collected. qRT⁃PCR was used to detect the expression levels of KLF7 , APN , IL⁃6 , and TNF⁃α mRNA in EAT. Human THP⁃1 cells were cultured in vitro and induced into M1 type macrophages and 3T3 ⁃L1 preadipocytes. The cells were divied into 3 groups : KLF7 up⁃regulated group ( transfected with KLF7 mimic) , KLF7 down⁃regulated group ( transfected with siRNA knockdown KLF7 ) , NC group ( transfected oligopeptide sequence) , transfected two kinds of cells. qRT⁃PCR was used to detect the expression of APN , MCP⁃1 , IL⁃6 and TNF⁃α mRNA in M1 type macrophages , and the protein expression levels of key factors in the NF⁃κB signaling pathway were detected by Westren blot. The qRT⁃PCR method was used to detect APN , KLF4 , IL⁃6 , MCP⁃1 mRNA and adipocyte differentiation marker peroxisome proliferator⁃activated receptor⁃γ (PPARγ) in 3T3 ⁃L1 preadipocytes 24 h after transfection. CCAAT/enhancer binding protein α (C/EBPα ) , fatty acid binding protein 4 (FABP4) mRNA relative expression levels , and Westren blot was used to detect protein expression levels. Results : Compared with the non⁃CAD group , the expression of CAD group decreased , APN decreased , IL⁃6 and TNF⁃α increased significantly , and the difference was statistically significant (P < 0. 01) . KLF7 was highly expressed in human THP⁃1 derived M1 macrophages induced by inflammatory stimuli (LPS) . In M1 macrophages derived from human THP⁃1 , knocking down KLF7 could inhibit the release of inflammatory factors. Transfection with KLF7 ⁃siRNA could significantly inhibit LPS⁃induced phosphorylation of JNK⁃MAPKs , the level of p⁃p65 and the activation of p ⁃IκBa (P < 0. 05) . In 3T3 ⁃L1 preadipocytes , upregulation of KLF7 increased the expression of adipocyte differentiation markers PPARγ , C/EBPa , FABP4 mRNA , and promoted the differentiation of 3T3 ⁃L1 preadipocytes into adipocytes (P < 0. 05) . Conclusion The expression of KLF7 in EAT in CAD patients increases. KLF7 activates the activation of macrophages mediated by the JNK⁃NF⁃KB signaling pathway in EAT , promotes inflammation in EAT in CAD patients , and promotes the differentiation and maturation of adipocytes , thereby promoting the development of CAD. It indicates that KLF7 may be a potential therapeutic target for cardiovascular diseases (such as CAD) .
