BACKGROUND: The use of potentially inappropriate medications (PIMs) is a major concern for medication safety as it may entail more harm than potential benefits for older adults. This study aimed to explore the prescribing rate, healthcare utilization, and expenditure of older adults using PIMs in China. METHODS: A cross-sectional analysis was conducted using a national representative database of all medical insurance beneficiaries across China, extracting ambulatory visit records of adults aged 65 years and above between 2015 and 2017. Descriptive analysis was conducted to measure the rate of patients exposed to PIM, prescribing rate of each PIM, average annual outpatient visits per patient, average total medication costs for each visit, average annual cost of PIMs for each patient, and average annual medication costs for each patient. Generalized linear model with logit link function and binomial distribution was used to examine the adjusted associations between PIMs and independent variables. RESULTS: In total, 845,278 (33.2%) participants were identified to be exposed to at least one PIM. Patients aged 75-84 years (38.1%, 969,809/2,545,430) and ≥85 years (37.9%, 964,718/2,545,430) were more likely to be prescribed with PIMs. Beneficiaries of the Urban Employee Basic Medical Insurance (UEBMI) and living in eastern and southern regions were more frequently prescribed with PIMs. Compared with patients without PIM exposure (7.5 visits, drug cost of RMB 1545.0 Yuan), patients with PIM exposure showed higher adjusted average annual number of outpatient visits (10.7 visits, β = 3.228, 95% confidence interval [CI] = 3.196-3.261) and higher annual drug costs (RMB 2461.8 Yuan, Coef. = 916.864, 95% CI = RMB 906.292-927.436 Yuan). CONCLUSIONS The results showed that the use of PIM among older adults was common in China. This study suggests that the use of PIM could be considered as a clear target, pending multidimensional efforts, to promote rational prescribing for older adults.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Abelmoschi Corolla, the dried corolla of Abelmoschus manihot, has anti-inflammatory, antioxidant, and anti-fibrosis activities. Its chemical constituents mainly include flavonoids, organic acids, steroids, and polysaccharides. This study reviewed the research progress in the chemical constituents and pharmacological activities of Abelmoschi Corolla in recent 20 years. According to the concept of quality marker(Q-marker), the Q-markers of Abelmoschi Corolla were predicted from plant phylogeny, chemical constituent specificity, traditional efficacy, chemical constituent measurability, and absorbed constituents. The primary Q-markers for Abelmoschi Corolla were anticipated to include quercetin-3'-O-β-D-glucopyranoside, gossypetin-8-O-β-D-glucuronide, isoquercetin, myricetin,quercetin, and hyperoside, with the aim of providing reference data for improving the quality evaluation system of Abelmoschi Corolla.

Cellulose synthase (CesA), one of the key enzymes in the biosynthesis of cellulose in plants, plays an important role in plant growth and plant resistance. In this study, a total of 21 AsCesA genes from Aquilaria sinensis were systematically identified and the physico-chemical characteristics were analyzed based on genome database and bioinformatical methods. The phylogenetic tree was constructed and the gene location on chromosome, cis-acting elements in the 2 000 basepairs upstream regulatory regions and conservative motifs were analyzed. The AsCesA proteins were mainly located on the plasma membrane. The number of amino acids of the proteins ranged from 390 to 1 261. The isoelectric point distributed from 5.67 to 8.86. All of the 21 AsCesA proteins possessed the transmembrane domains, the number of which was from 6 to 8. The genes were classified into 3 groups according to the phylogenetic relationship. Obvious differences were observed in motif composition in genes from different groups. However, motif2, motif6, motif7 and motif10 were observed in all of AsCesA proteins. Analysis of cis-acting elements indicated that AsCesA genes family has cis-acting elements related to plant hormones, abiotic stresses, and biological processes. Seven AsCesA genes with differential expression were selected according to the calli transcriptome data induced by NaCl at different times and their expression levels under different abiotic stresses were analyzed by quantitative real-time PCR. The results indicated that salt, low temperature, drought, and heavy metal stresses could affect the expression level of AsCesA genes, and the abundance of AsCesA1, AsCesA3 and AsCesA20 showed a significant change, implying their potential important roles to the abiotic stresses. The accumulation pattern of cellulose content under different abiotic stresses was similar to the expression trend of AsCesA genes. Our results provide valuable insights into the role of cellulose synthase in A.sinensis in plant defense.

Objective:To construct and evaluate a predictive model for the recurrence of hepatolithiasis after surgery based on clinical data and serum retinol binding protein 4 (RBP4) and cholecystokinin A (CCK-A). Methods:One hundred and thirty-five patients with intrahepatic duct stone who underwent laparoscopic combined choledochoscopic lithotripsy admitted to our hospital from January 2020 to December 2022 were retrospectively included and divided into a modeling set (n=90) and a validation set (n=45) according to a 2:1 ratio. Patients were divided into relapse group and non-recurrence group according to recurrence status within 1-year follow-up. Univari-ate Logistic regression analysis was performed to analyze the influencing factors of postoperative recurrence of patients. A nomogram was constructed according to the influencing factors,and cali-bration curve,consistency index,receiver operating characteristic curve (ROC) and decision curve were used for internal and external verification. Results:In the modeling set,patients with bilat-eral stone distribution,maximum stone diameter ≥10 mm,bile duct stenosis,multiple stone num-bers,and paracystic diverticulum in the recurrent group had higher serum levels of RBP4 than those in the non-recurrent group at 7 days after surgery,and lower serum levels of CCK-A than those in the non-recurrent group at 7 days after surgery (P<0.05). The factors of recurrence after hepatoli-thiasis surgery were the maximum stone diameter ≥10 mm,bilateral stone distribution,bile duct stenosis,multiple stone numbers,paracystic diverticulum,serum RBP4 level 7 days after surgery,and serum CCK-A level 7 days after surgery (P<0.05). A nomogram was constructed based on the influencing factors,and internal and external validation showed that the prediction model had good predictive ability and clinical net benefit. Conclusion:The influencing factors of recurrence after hepatolithiasis surgery include serum RBP4 levels 7 days after surgery and bilateral stone distribu-tion. The nomogram prediction model constructed based on these factors has high predictive value and clinical benefit.

OBJECTIVE To provide reference and suggestions for dynamic adjustment of classification management lists for clinical use of antibiotics and the promotion of rational use of antibiotics. METHODS The latest version of provincial classification management lists for clinical use of antibiotics were aggregated into the “national list”， which was compared with 2021 WHO AWaRe classification list of antibiotics （hereinafter referred as to “AWaRe classification list”） to make a descriptive statistical analysis about the number of different classes of antibiotics in the two lists and their differences. RESULTS Based on the different classification principles， 262 kinds of antibiotic preparations in the national list were classified into non-restricted （84）， restricted （83） and highly-restricted classes （95）， and 258 kinds in the AWaRe classification list were classified into access （87）， watch （142） and reserve classes （29）； 182 kinds of antibiotic preparations were both included in the two lists. In the national list， among the non-restricted antibiotic preparations， 36 kinds belonged to access class， 30 belonged to watch class and 1 belonged to reserve class； among restricted antibiotic preparations， 7 belonged to access class， 46 kinds belonged to watch class and 3 belonged to reserve class； among highly-restricted antibiotic 82805019。E-mail：yyy211anne@163.com preparations， 9 belonged to access class， 35 belonged to watch class and 15 kinds belonged to reserve class. Among them， 91 kinds of antibiotic preparations were not recommended by WHO （20 kinds） or not included in the AWaRe classification list （71 kinds）. CONCLUSIONS The classification methods of two lists are different in classification principles and grading of some similar drugs. The classification management list of antibiotics is one of the key points of antibiotics management， more research is needed in the future to provide sufficient evidence for optimizing antibiotics classification management.
