BACKGROUND: The mechanisms distinguishing metabolically healthy from unhealthy phenotypes within the same BMI categories remain unclear. This study aimed to investigate the associations between regional fat distribution and metabolically unhealthy phenotypes in Chinese adults across different BMI categories. METHODS: This cross-sectional study involving 11833 Chinese adults aged 20 years and older. Covariance analysis, adjusted for age, compared the percentage of regional fat (trunk, leg, or arm fat divided by whole-body fat) between metabolically healthy and unhealthy participants. Trends in regional fat percentage with the number of metabolic abnormalities were assessed by the Jonckheere-Terpstra test. Odds ratios (ORs) and their 95% confidence intervals (CIs) were estimated by logistic regression models. All analyses were performed separately by sex. RESULTS: In non-obese individuals, metabolically unhealthy participants exhibited higher percent trunk fat and lower percent leg fat compared to healthy participants. Additionally, percent trunk fat increased and percent leg fat decreased with the number of metabolic abnormalities. After adjustment for demographic and lifestyle factors, as well as BMI, higher percent trunk fat was associated with increased odds of being metabolically unhealthy [highest vs. lowest quartile: ORs (95%CI) of 1.64 (1.35, 2.00) for men and 2.00 (1.63, 2.46) for women]. Conversely, compared with the lowest quartile, the ORs (95%CI) of metabolically unhealthy phenotype in the highest quartile for percent arm and leg fat were 0.64 (0.53, 0.78) and 0.60 (0.49, 0.74) for men, and 0.72 (0.56, 0.93) and 0.46 (0.36, 0.59) for women, respectively. Significant interactions between BMI and percentage of trunk and leg fat were observed in both sexes, with stronger associations found in individuals with normal weight and overweight. CONCLUSIONS Trunk fat is associated with a higher risk of metabolically unhealthy phenotype, while leg and arm fat are protective factors. Regional fat distribution assessments are crucial for identifying metabolically unhealthy phenotypes, particularly in non-obese individuals.

OBJECTIVE: To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients. METHODS: In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation. RESULTS: When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group. CONCLUSIONS Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period.

AIM To evaluate the habitat suitability of Hedysari Radix based on MaxEnt model and ArcGIS.METHODS Using the MaxEnt model to screen the ecological factors affecting the distribution of Hedysari Radix,an evaluation model was thus established.ArcGIS software was used to evaluate the ecological suitability of Hedysari Radix to obtain the data about the highly suitable area,the moderate suitable area,the low suitable area and non-suitable area for its growth in China.RESULTS Hedysari Radix found its 1.29×106 km2 suitable area in China,among which the highly suitable area was 5×104 km2,mainly in Gansu Province,the moderately suitable area was 3.38×105 km2,and the low-suitable area was 9×105 km2,occupying 4.03%,26.20%and 69.77%of all,respectively.The main ecological factors affecting the distribution of Hedysari Radix were determined to be altitude,precipitation in the hottest quarter,solar radiation in September and December,seasonal temperature variation deviation and basic saturation of upper soil(0-30 cm).CONCLUSION With its result complying well with the literature records,this study provides theoretical basis for the introduction and cultivation of Hedysari Radix,and sustainable utilization of resources as well.

Objective To evaluate the effect of targeted monitoring and multi-modular improvement strategy on the prevention and control of catheter-associated urinary tract infection(CAUTI).Methods Patients with indwe-lling urinary catheter in a tertiary first-class hospital from January 2018 to December 2022 were selected as the re-search subjects.Targeted monitoring results and distribution of pathogenic bacteria in 5 consecutive years were ana-lyzed,and a multi-modular improvement strategy based on the targeted monitoring results was implemented.The occurrence of CAUTI before and after implementation,status and effectiveness of training in prevention and control measures were compared respectively.Results Before and after the implementation of the multi-modular improve-ment strategy,health care workers'compliance rate of hand hygiene,awareness rate of prevention and control measures,and implementation rate of prevention and control measures all increased significantly(all P＜0.001).Targeted monitoring results showed that daily test rates of urine culture and routine urine from patients with in-dwelling catheters have been on the rise in 5 consecutive years(P＜0.05).A total of 397 cases of CAUTI occurred in the past 5 years.Incidences of CAUTI in general intensive care unit(ICU)and surgical ICU showed decreasing trends in 5 consecutive years(all P＜0.05).Incidence of CAUTI in general wards showed no statistically significant difference in 5 years(P=0.088).A total of 431 strains of pathogenic bacteria were detected,mainly Gram-negative bacteria.Daily incidence of multidrug-resistant organism infection in patients with indwelling catheters was 0.12‰.After the implementation of the multi-modular improvement strategy,incidence of CAUTI in all departments re-duced significantly(P＜0.05).Conclusion Targeted monitoring can help identify departments with high-risk of CAUTI,multi-modular improvement strategy can raise the quality of prevention and control of CAUTI in all occa-sions,reduce the incidence of CAUTI,and is worthy of clinical promotion and application.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Objective:To understand the awareness of AIDS related knowledge and prevalence of extramarital sexual behaviors in HIV-infected men aged ≥50 years in Chongqing, and provide scientific evidence for the development of prevention and control measures.Methods:From July to December 2021, a random sampling method was used to recruit 800 HIV-infected men aged ≥50 years in Yubei, Kaizhou, Jiangjin and Shapingba Districts of Chongqing for a face-to-face questionnaire survey. The logistic regression model was used to analyze relevant factors of AIDS knowledge awareness and prevalence of extramarital sex behavior. The SPSS 26.0 software was used for statistical analysis.Results:The average age were (62.5±8.6) years in 698 of HIV-infected men aged ≥50 years.The overall awareness rate of AIDS related knowledge was 66.91% (467/698), the incidence of non-marital sexual behavior in last year was 6.73% (47/698), and the consistent condom use rate was 61.70% (29/47). Multivariate analysis showed that the awareness rate of AIDS related knowledge was lower in those aged ≥70 years (a OR=0.60, 95% CI: 0.40-0.91) and those aged ≥60 years (a OR=0.61, 95% CI: 0.41-0.90) and those with other marital status (a OR=0.70, 95% CI: 0.50-0.98), and the awareness rate of AIDS related knowledge was higher in those with education level of junior high school or above (a OR=5.90, 95% CI: 3.34-10.44). Those with widowed/divorced/unmarried marital status (a OR=13.01, 95% CI: 6.11-27.71) and those using sexual aids in the last year (a OR=8.72, 95% CI: 2.76-27.55) had higher prevalence of non-marital sexual behavior. Conclusions:HIV-infected men aged ≥50 years in Chongqing had lower awareness of AIDS related knowledge, a certain percentage of non-marital sex, and lower condom use rate. It is suggested to strengthen the health education about sexual health and the promotion of condom use in this population.

OBJECTIVE: This study evaluated the effect of maximal oxygen pulse (O ₂P _max) on patients with chronic obstructive pulmonary disease (COPD) and confirmed the predictive effect on acute exacerbations of COPD (AECOPD). METHODS: This retrospective study included 91 participants who underwent cardiopulmonary exercise testing (CPET), lung function testing, a dyspnea scale assessment, and a 3-year follow-up. The participants were divided into two groups according to the O ₂P _max value. Exercise capacity, ventilatory conditions, gas exchange efficiency, and dyspnea symptoms were compared, and the correlations between O ₂P _max and these indices were evaluated. The ability of O ₂P _max to predict AECOPD was examined. RESULTS: Exercise capacity, ventilatory conditions, and gas exchange efficiency were lower, and dyspnea symptom scores were higher in the impaired O ₂P _max group ( P < 0.05). O ₂P _max was positively correlated with forced vital capacity (FVC)%, forced expiratory volume in 1 sec (FEV ₁)%, FEV ₁/FVC%, anaerobic threshold (AT), work rate (WR)%, aximal oxygen uptake (V̇O _2max)%, V̇O ₂/kg _max, V̇O ₂/kg _max%, WR _AT, WR _max, V̇O _2AT, V̇O _2max, and V̇ _Emax, and was negatively correlated with EqCO _2AT, and EqCO _2max ( P < 0.05). Most importantly, O ₂P _max could be used to predict AECOPD, and the best cut-off value was 89.5% (area under the curve, 0.739; 95% CI, 0.609-0.869). CONCLUSION O ₂P _max reflected exercise capacity, ventilation capacity, gas exchange capacity, and dyspnea symptoms in patients with COPD and may be an independent predictor of AECOPD.
