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.

Objective: To investigate the technical considerations and clinical value of plasma exchange (PE) in the treatment of cardiohepatic syndrome (CHS). Methods: A 76-year-old male patient with CHS was treated. The patient’s underlying conditions included valvular heart disease (severe mitral and tricuspid regurgitation), chronic heart failure (cardiac function class IV) complicated with liver failure [total bilirubin (TBIL) up to 590.6 μmol/L; alanine aminotransferase (ALT) up to 325.4 IU/L; aspartate aminotransferase (AST) up to 190.4 IU/L]. Due to poor response to conventional anti-heart failure and hepatoprotective therapy, three sessions of stepwise PE (total volume 6 400 mL) were performed. A "calcium-fluid balance-hemodynamics“ trinity monitoring system was established during treatment, comprising:1) prophylactic calcium supplementation (continuous calcium infusion at 5 mL/h initiated before PE); 2) dynamic blood gas monitoring (ionized calcium measured every 30-60 min with calcium dose adjusted accordingly); 3) individualized fluid balance setting (75%-90%); 4) standby norepinephrine (0.02-0.1 μg/kg/min). Results: Complications such as hypocalcemia (lowest 0.83 mmol/L) and hypotension (lowest 65/38 mmHg) occurred during treatment. Hemodynamics were stabilized by adjusting calcium supplementation, regulating fluid balance, and concomitant use of vasoactive agents. After treatment, B-type natriuretic peptide (BNP) decreased by 42.0% (from 7 122.53 pg/mL to 4 128.77 pg/mL), TBIL decreased by 69.7% (from 590.6 μmol/L to 178.7 μmol/L), ALT decreased by 91.8% (from 325.4 IU/L to 26.7 IU/L), and AST decreased by 83.2% (from 190.4 IU/L to 31.9 IU/L). Conclusion: PE based on the "calcium-fluid balance-hemodynamics" trinity monitoring system can improve cardiac and liver function in patients with CHS.

Objective: To accurately determine ABO blood groups through serological and molecular biological tests in patients whose forward typing was group O but who showed weak antibodies on one side of reverse typing, thereby ensuring precise transfusion. Methods: A total of 160 cases from 2023 to 2025 at Tianjin Blood Center, initially screened as O type with weak antibodies or missing antibodies on one side of reverse typing, were collected. Serological tests absorption-elution tests, and molecular biological tests were performed to accurately identify their ABO blood groups and ensure transfusion safety. Results: Among the 160 patients with forward typing as O type and weak antibodies on one side of reverse typing, 92 were identified as O type, 46 as ABO subtypes already named and recorded by ISBT (mainly including 18 cases of Ael02, 8 cases of AW37, and 9 cases of Bel03), 12 suspected as new alleles not yet recorded by ISBT (among which 5 were suspected to carry novel alleles that have not been recorded or reported in the literature), and 10 were suspected as weakened A/B antigens. Conclusion: In clinical transfusion, attention should be paid to cases with ABO forward-reverse discrepancy, where forward typing is O type and reverse typing shows weak antibodies on one side. These cases may involve ABO subtypes, and further testin is necessary to accurately determine the ABO blood group, achieve precise transfusion, and avoid blood wastage.

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 study the mechanism by which acoustic wave stimulation improves cognitive function in sleep-deprived mice.Methods(1)Thirty-six male C57BL/6 mice were randomly divided into three groups:the control group,model group and acoustic wave group(n=12 per group).A sleep deprivation model was established using the modified multiple platform method.After 21 days of sleep deprivation in a row,mice in the acoustic wave group were exposed to 30-minute acoustic wave stimulation at 40 dB.(2)During sleep deprivation,the health status of each group of mice was recorded,including the mental state and body weight.(3)After 21 days of sleep deprivation,behavioral tests(open field test,novel object recognition test,Y-maze and Morris water maze)were performed to assess the spontaneous activity,spatial exploration,and such cognitive functions as learning and memory in mice.Immunohistochemistry was conducted to analyze the expressions of neuronal nuclear antigen(NeuN),glial fibrillary acidic protein(GFAP)and ionized calcium-binding adaptor molecule 1(Iba-1)in the hippocampus.Quantitative real-time PCR(qPCR)was used to measure the expression levels of interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α)and inducible nitric oxide synthase(iNOS)in the hippocampus.(4)Transcriptome sequencing was employed to explore the mechanism underlying the improvement of cognitive impairment by acoustic wave stimulation.Results After 21 days of sleep deprivation,acoustic wave stimulation significantly alleviated weight loss in mice(P＜0.01).The accuracy of Y-maze spontaneous alternation,indexes of novel object discrimination,the time spent in the target quadrant and the number of times the mice crossed the platformin the Morris water maze were all significantly increased(P＜0.05),while the escape latency was significantly reduced(P＜0.05).The average optical density of NeuN in the hippocampal CA3 region significantly increased(P＜0.05),GFAP and Iba-1 immunopositive cell counts significantly decreased(P＜0.01),and the mRNA levels of IL-6,TNF-α,and iNOS in the hippocampal tissue were significantly reduced(P＜0.05).Conclusion Acoustic wave stimulation can repair neural damage,modulate hippocampal inflammatory responses,and improve cognitive deficits induced by sleep deprivation.
