Over the past two decades, genome-wide association study(GWAS) has identified numerous genetic variants and loci associated with heritable diseases. With the gradual maturation and saturation of GWAS methodologies, transcriptome-wide association study(TWAS) offers a novel perspective by linkinggenetic phenotypes to gene expression levels. By integrating TWAS with other multi-omics analyses, researchers can gain a deeper understanding of heritable diseases. This article provides an overview of recent groundbreaking and representative TWAS methods and tools, analyzes their strengths and limitations, and discusses future trends in TWAS development.

OBJECTIVE To investigate the prevalence and influencing factors of potentially inappropriate medication （PIM） among the elderly in nursing homes in Urumqi based on three PIM screening tools， and to compare the applicability of different tools. METHODS A cross-sectional study design was adopted. Elderly individuals from six nursing homes in Urumqi were selected as the research subjects from May 2021 to September 2023. Demographic characteristics， disease burden and medication records of the elderly were collected. PIM screening was performed using the Chinese PIM criteria （2024 edition）， the American Geriatrics Society （AGS） Beers criteria （2023 edition）， and the Screening Tool of Older Person’S Prescriptions（STOPP）/Screening Tool to Alert to Right Treatment（START） （2023 edition）. Fleiss’s Kappa test was used to assess the consistency among the three screening tools， and multivariate Logistic regression was used to analyze the influencing factors of PIM. RESULTS The prevalence of PIM screened by the Chinese PIM criteria was 47.4% （323/682）， by the AGS Beers criteria was 43.4% （296/682）， and by the STOPP criteria was 50.9% （347/682）. The consistency among the three screening tools was low （Fleiss’s Kappa＝0.12， P ＜0.001）. Multivariate Logistic regression analysis showed that all three screening tools indicated that polypharmacy， aspirin use and psychotropic drug use were independent risk factors for PIM among elderly in nursing houses （all OR＞1， P ＜0.05）. CONCLUSIONS The prevalence of PIM among the elderly in nursing homes in Urumqi is relatively high. Polypharmacy， aspirin use and psychotropic drug use are common independent risk factors for PIM. There are differences in screening results among the three tools with low consistency. The Chinese PIM criteria can serve as a first-line tool for PIM screening in nursing homes.

Background: Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA). Methods: Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound. Results: In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation. Conclusions Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.

Objective To explore the correlations between interleukin-6(IL-6),interleukin-8(IL-8),antimicrobial peptide LL-37 and the microbial abundance and the degree of mucosal injury in patients with trichomonal vaginitis(TV).Methods A total of 120 TV patients admitted from January 2022 to December 2024 were selected and divided into the occurrence group(n=63)and the non-occurrence group(n=57)according to presence and absence of mucosal injury.The general data,IL-6,IL-8,LL-37 and microbial abundance were compared between the two groups.According to the degree of mucosal injury,the occurrence group was divided into the mild subgroup(n=34),the moderate subgroup(n=20),and the severe subgroup(n=9).Pearson correlation analysis was applied to investigate the correlations between IL-6,IL-10,antimicrobial peptide LL-37,microbial abundance and the degree of mucosal injury.Multivariate logistic regression was used to analyze the influencing factors of mucosal injury in TV patients.The receiver operating characteristic curve(ROC)was used to evaluate the predictive value of relevant indicators for mucosal injury in TV patients.Result The levels of IL-6,IL-8,antimicrobial peptide LL-37,and the abundance of Actinobacteria and Gardnerella in the occurrence group were higher than those in the non-occurrence group,while the abundance of Firmicutes and Lactobacillus was lower than that in the non-occurrence group(P<0.05,P<0.01).Pearson correlation analysis showed that IL-6,IL-8,antimicrobial peptide LL-37,and abundance of Actinobacteria and Gardnerella were positively correlated with the degree of mucosal injury(r=0.543,0.713,0.352,0.409,0.659,P<0.01),while the abundance of Firmicutes and Lactobacillus was negatively correlated with the degree of mucosal injury(r=-0.540,-0.504,P<0.01).Multivariate logistic regression analysis showed that IL-6,IL-8,antimicrobial peptide LL-37,and abundance of Actinobacteria were risk factors for mucosal injury in TV patients,while the abundance of Firmicutes and the abundance of Lactobacillus were protective factors(P<0.05).The ROC curve showed that the area under the ROC curve(AUC)of the combined detection of IL-6,IL-8,antibacterial peptide 37,and the abundance of Actinobacteria,Firmicutes,and Lactobacillus in evaluating mucosal injury in TV patients was higher than that of the single detection(P<0.01).Conclusion IL-6,IL-8,antimicrobial peptide LL-37 and microbial abundance are closely related to the degree of mucosal injury in TV patients.The combined detection has a high value in evaluating the occurrence of mucosal injury in TV patients.

Objective:To explore the dynamic change trajectory and influencing factors of postoperative fatigue (POF) in patients with early digestive tract cancer undergoing endoscopic submucosal dissection (ESD), so as to provide theoretical basis for individualized management of such patients.Methods:Using cross-sectional survey and convenient sampling method, the patients who underwent ESD for early cancer of digestive tract in the endoscopic center of the Second Affiliated Hospital of Zhejiang University School of Medicine from January to June 2024 were selected as the research objects. The questionnaires were conducted at 30 min, 24 h, 3 days, 5 days, 7 days after ESD with Christensen's postoperative fatigue score. Spearman test was used to analyze the correlation between pain, insomnia and POF. The latent variable growth model was used to identify the potential categories of POF trajectory, and the influencing factors were analyzed by Logistic regression.Results:A total of 232 patients were finally induded, with ages of 19-94(59.53 ± 13.29) years, including 120 males and 112 femalss. The POF level of patients with early cancer of digestive tract showed a downward trend one week after operation. Three postoperative fatigue trajectories were fitted, 9.05% in moderate or severe fatigue low-speed smooth descent group (C1 group); 32.76% in moderate fatigue first decreased quickly and then slowly group (C2 group) and 58.19% in mild fatigue continuous decline group (C3 group). The result of Logistic regression analysis showed that, compared with C1 group, people without religious beliefs were morelikely to enter C2 group [ β = 1.572, OR = 4.818(1.033 - 22.465), P<0.05]; compared with C3 group, patients with high pain level and severe insomnia degree were likely to enter C1 [ β = 2.621, 0.663, OR were 13.754(2.692 - 70.283) and 1.942(1.429 - 2.638), both P<0.05] and C2 [ β = 2.010, 0.491, OR were 7.464(1.890 - 29.482) and 1.634(1.348 - 1.982), both P<0.05] group. Conclusions:There were three potential types of POF in patients with early digestive tract cancer ESD. Medical staff should pay attention to patients with severe insomnia, intense pain and religious beliefs, and give staged fatigue assessment and individualized intervention, so as to reduce the level of POF and promote rapid recovery.

Objective:To analyze the effects of Mulligan technique combined with isokinetic exercise training (IET) on isokinetic muscle strength and neuromuscular control ability in patients with knee osteoarthritis (KOA).Methods:A retrospective case-control study was conducted. A total of 49 patients with KOA who underwent IET at Honghui Hospital Affiliated to Xi'an Jiaotong University from January 2021 to January 2022 were included in the control group. An additional 49 patients with KOA who received Mulligan technique and IET at the same hospital from June 2022 to June 2023 were included in the observation group. Both groups were treated for 8 successive weeks. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Lysholm score, proprioception metrics [including average track error (ATE) and test time execution (TTE)], isokinetic muscle strength [peak torque (PT) and average power (AP) for flexors and extensors at 60°/s, 90°/s, and 120°/s)]were compared between the two groups before and after 4 and 8 weeks of intervention. Additionally, Visual Analog Scale score was compared between the two groups at baseline and after 8 weeks of intervention.Results:There was no statistically significant difference in WOMAC score, Lysholm score, or PT and AP levels for flexor and extensor muscles at 60°/s, 120°/s, and 180°/s between the two groups before intervention (all P > 0.05). After 4 and 8 weeks of intervention, the levels of PT and AP for both flexors and extensors at 60°/s, 120°/s, and 180°/s, as well as the Lysholm scores, were significantly higher in the observation group compared with the control group [PT level: t = -0.10, -3.03, -3.85, -0.35, -3.62, -3.95, -0.27, -5.51, -6.52, -1.13, -2.74, -3.68, -0.09, -2.91, -5.79, -0.13, -4.66, -6.05; AP level: t = -0.23, -4.77, -6.15, 0.01, -3.10, -3.75, -0.13, -3.73, -3.44, 0.16, -2.09, -4.05, -0.17, -3.71, -3.51, -0.27, -3.26, -3.69; Lysholm score: t = -7.17, -6.44; all P < 0.05]. After 4 and 8 weeks of intervention, the WOMAC score, ATE, and TTE in the observation group were significantly lower than those in the control group [WOMAC score: t = 3.68, 0.64; ATE level: t = 3.88, 4.13; TTE level: t = 4.86, 4.60; all P < 0.05]. After 8 weeks of intervention, both groups had lower Visual Analog Scale scores compared with their scores before the intervention (U control group = -8.75, U observation group = -8.63), with the observation group showing significantly lower scores than the control group ( U = -5.95, P < 0.001). Conclusions:The Mulligan technique combined with IET can effectively alleviate knee joint pain in patients with KOA, promote the recovery of knee joint function, enhance proprioceptive recovery, and improve neuromuscular control abilities.

Objective To understand the experience of fall alertness in elderly patients with rheumatoid arthritis and to provide references for the development of targeted nursing intervention strategies.Methods 13 elderly patients with rheumatoid arthritis,who were admitted to the Department of Rheumatology and Immunology of a tertiary hospital in Guizhou Province from February to April 2024,were selected through purposive sampling.Phenomenological qualitative research methods were used,with semi-structured in-depth interviews.Data were analyzed using Colaizzi's seven-step method,and themes were extracted.Results 3 main themes and 9 sub-themes were identified:the process of fall risk perception(reshaping fall risk cognition,establishing emotional coping mechanism,enhancing fall alertness effect),behavioral responses to fall alertness(creating a safe living environment,regularizing daily routine plan),and needs for fall prevention support(need for fall prevention knowledge,home rehabilitation care needs,intelligent device usage needs,psychosocial support needs).Conclusion Clinical medical staff should pay attention to the transformation process of fall risk perception in elderly rheumatoid arthritis patients,accurately identify patients'fall support needs in practice,and guide patients to adopt appropriate fall alert response behaviors through innovative fall demand support interaction paths and the construction of social support network systems,in order to improve patients'fall alertness and reduce their fall risk.

Objective:To evaluate the application value of interactive learning in enhancing the diagnosis of breast cancer by residents in the department of radiology through training based on the interpretation of breast magnetic resonance imaging (MRI) features by the breast imaging reporting and data system (BI-RADS).Methods:A total of 23 trainees completed BI-RADS standardized reports of 250 cases. These cases were divided into a pre-training group (Group 1) and post-training groups (initial training, Groups 2-4; advanced training, Groups 5-6), forming a total of six groups. The efficacy of interactive learning through course lectures and case-based practice in enhancing their ability in breast cancer diagnosis was analyzed. All trainees generated reports based on the BI-RADS scoring criteria. Interpretation agreement rates, evaluation time, and confidence levels were recorded. SPSS 25.0 was used for independent samples t test, chi-square test, and rank-sum test. Results:During the initial stage of training, the agreement rate of 150 cases reached 80.00%, which was recommended as the endpoint for completion of the initial learning phase. A significant difference existed between Group 4 and Group 1 ( P=0.012) in agreement rate. Statistically significant differences were noted in evaluation time for Groups 5 and 6 before and after advanced training ( P=0.001 and 0.007, respectively). A significant difference in confidence level was observed for Group 5 ( P=0.005). Conclusions:Interactive training based on BI-RADS standardized reporting can improve the diagnosis of breast diseases by residents in the department of radiology, particularly for enhancing the quality of reports for mass-like enhancement breast diseases.
