OBJECTIVE To screen and quantitatively analyze the quality marker （Q-Marker） associated with anti-renal fibrosis in Shenqi shenshuai mixture （SQSS）， so as to provide references for the analysis of pharmacodynamic substances and new drug transformation of SQSS. METHODS The chemical components of SQSS were characterized by untargeted metabolomics. Combined with network pharmacology， gene expression omnibus （GEO） and connectivity map （CMAP） databases， the anti-renal fibrosis Q-Markers of SQSS were screened. HPLC-MS/MS was applied to determine the contents of Q-Markers in 10 batches of SQSS. RESULTS A total of 1 319 compounds were identified from SQSS via untargeted metabolomics，and 84 active ingredients with anti-renal fibrosis activity were further screened out， such as formononetin. Nine anti-renal fibrosis Q-Markers were obtained by network pharmacology and GEO database， including berberine， quercetin， honokiol， nicotinamide， daidzein， coumarin， kaempferol， formononetin and amygdalin. The quantitative results showed that the average contents of the above components （excluding amygdalin） in 10 batches of SQSS were 2.523， 1.942， 26.848， 1.415， 0.692， 0.171， 0.374， 7.401 μg/mL， respectively. CONCLUSIONS Nine anti-renal fibrosis Q-Markers of SQSS were screened in this study， and the contents of eight among them were determined. The results can provide a basis for elucidating the pharmacodynamic material basis and promoting the new drug transformation of SQSS.

IL-32 is a multifunctional cytokine with both pro-inflammatory and anti-inflammatory properties.It has been proved that expression of IL-32 increases with progression of gastric mucosal diseases and severity of gastric cancer(GC),thus participating in process of gastric"inflammation-cancer"transformation.However,how IL-32 affects malignant transformation of gastric"inflamma-tion-cancer"and finally leads to adverse outcome of GC invasion and migration is still controversial.In order to better clarify regulatory effect and possible mechanism of abnormal expression of IL-32 on different histopathological stages of gastric"inflammation-cancer"transformation,and to explore new directions and breakthroughs in molecular mechanism of early truncation and treatment of gastric precancerous lesion(GPL),we searched literatures related to IL-32 in six authoritative databases at home and abroad,such as Pubmed,Web of Science and CNKI,in past 30 years.It was found that pathogenicity or protective function of IL-32 in different histo-pathological stages of gastric"inflammation-cancer"transformation depended on its different subtypes,secretory forms,surrounding cytokine environment,disease status and genetic factors.IL-32 may regulate polarization of macrophages through NF-κB,MAPK,COX2,PR3,IDO,NOD,PKCδ,FAK and STAT3,amplify or inhibit chronic inflammatory stimulation of gastric mucosa,and thus participate in process of gastric"inflammation-cancer"transformation.Our new understanding of role of IL-32 in different stages of Cor-rea cascade may contribute to development of cytokine-directed therapy,and therapy aimed at regulating different alternative splicing subtypes of IL-32 and targeting IL-32 signals can be used as a new strategy for medical treatment of GPL and GC in future.

Robot-assisted surgery with its advantages such as three-dimensional high-definition vision, dexterous robotic arms, and tremor filtration, is increasingly being applied to complex radical gastrectomy. However, the role of the surgical assistant remains crucial during the procedure. The assistant is responsible for tasks outside the console, including adjusting robotic arms, changing instruments, exposing the surgical field, and addressing unexpected situations. The technical proficiency of the assistant and their collaboration efficiency with the primary surgeon directly impact the smoothness of surgery and patients' outcomes. With the expansion of robot-assisted surgical indications, the establishment of a standardized training system and the optimization of team collaboration models have become urgent challenges to address. This article draws on the author's practical experience as an assistant in robot-assisted gastric cancer surgeries, conducting an in-depth analysis of the responsibilities and operational skills of surgical assistants in robot-assisted procedures. The aim is to develop a relatively comprehensive set of operational guidelines for surgical assistants in robot-assisted radical gastrectomy, providing valuable references for enhancing the overall efficiency of surgical teams and improving surgical outcomes.

Green development has become a consensus,yet hospitals exhibit high energy intensity during operations.The requirement to"reduce energy expenditure per 10,000 yuan of revenue"necessitates energy conservation in hospital logistics.This study,based on the practical context of a hospital,innovatively introduced third-party verification,employing separate mete-ring and comprehensive electrical testing for energy savings accounting.Through the Energy Performance Contracting(EPC)model,the study addressed financial,technical,and managerial challenges in hospital energy conservation.Technological trans-formations included:Construction of an energy consumption monitoring system Intensive power supply and distribution system up-grades High-efficiency lighting systems Centralized air conditioning control Smart recycled water systems Real-time water quality monitoring BIM-based energy room operations These measures significantly reduced operational costs,achieving dual environmen-tal and economic benefits.As carbon neutrality goals advance,hospitals will increasingly focus on green and low-carbon transi-tions.The EPC model provides an effective pathway for hospitals to achieve energy conservation and emission reduction.

Objective To develop and translate the Chinese listening self-efficacy questionnaire(C-LSEQ)and to test its reliability and validity.Methods A total of 172 subjects aged≥60 years with age-related hearing loss completed the C-LSEQ questionnaire via direct interviews.Pure tone hearing threshold test,Mandarin hearing in noise test,and the hearing handicap inventory for elderly-screening(HHIE-S)were evaluated.Twenty subjects were randomly selected from the original group to complete the C-LSEQ questionnaire in 2 weeks after the initial evaluation.Results ① Reliability:The Cronbach's a coefficients of the three sub-dimensions and the overall ques-tionnaire were all＞0.8,and the test-retest reliability coefficients of the three sub-dimensions and the overall ques-tionnaire were all＞0.9(P＜0.001).② Validity:The experts collectively evaluated the representativeness of the statements with good content validity.The convergent validity test showed that the composite reliability(CR)of the 2 sub-dimensions and the overall questionnaire were all＞0.7,and the average variance extracted(AVE)were all＞0.5.The CR value of the complex listening dimension was 0.655,and the AVE value was 0.937.The criterion validity test showed that the overall questionnaire and the three sub-dimensions of the C-LSEQ were significantly correlated with the pure-tone average,speech recognition thresholds in noise,and HHIE-S(P＜0.001).Conclusion The C-LSEQ exhibits stable structure,with good reliability and validity.It can be used to assess listen-ing self-efficacy in adults with hearing loss,especially in the elderly with age-related hearing loss.

Objective To examine the correlation between fetal rectal ampulla diameter and gestational age,and to establish reference value ranges for low-risk fetuses between 18 and 40 weeks of gestation in Yibin region.Methods A total of 1,103 low-risk singleton pregnant women between 18 and 40 weeks of gestation were recruited from five hospitals in Yibin City(the Second People's Hospital,the First People's Hospital,the Fifth People's Hospital,the Maternal and Child Health Hospital of Yibin City,and the Maternal and Child Health Hospital of Cuiping District)for routine level Ⅰ,Ⅱ,and Ⅲ prenatal ultrasound screening from October 2022 to March 2024.Fetal rectal ampulla diameters,including anteroposterior diameter,transverse diameter,and area,were measured using prenatal ultrasound.The normality of these measurements was assessed using the Shapiro-Wilk test.Scatter plots depicting the relationship between fetal rectal ampulla diameter parameters and gestational age were generated using the"Overlap Scatter Plot"function in SPSS.Percentiles were calculated using the"Explore"function in SPSS,with reference value ranges described by P5,P10,P50,P90,and P95.Results The visual-ization rate of the fetal rectal ampulla diameter was 55%at 18～20 weeks of gestation,100%at 21～37 weeks,and 96%at greater than 37 weeks.The fetal rectal ampulla diameter exhibited a significant positive correlation with gestational age(r=0.925～0.949,P<0.01).Conclusions Prenatal ultrasound measurement of fetal rectal ampulla diameter demonstrates a robust correlation with gestational age.The reference intervals for the rectal ampulla diameter of low-risk fetuses between 18 and 40 weeks of gestation,established in this study,may offer valuable theoretical guidance for prenatal diagnosis of fetal rectal and anal abnormalities in Yibin region.
