OBJECTIVE T o analyze the distribution and clinical characteristics of carbapenem-resistant organisms(CRO)in the intestinal and respiratory tracts of high-risk ICU patients,and to evaluate the effectiveness of two screening methods:plate screening and Gene Xpert Carba(hereinafter referred to as Xpert Carba).METHODS In-testinal samples(anal swabs,feces)and respiratory samples(sputum,lavage fluid)from 320 patients admitted to the ICU ward of the Fourth Affiliated Hospital of Soochow University from Apr.2023 to Dec.2024 were collected.Plate screening and Xpert Carba methods were used for active screening of CRO strains,and clinical data of patients were collected through electronic medical records.RESULTS The plate screening results indicated that 70 out of 573 samples from 320 patients tested positive for CRO,with a positive rate of 12.22％(70/573).The positive rates for anal swabs,feces,sputum and lavage fluid were 9.26％(20/216),10.39％(8/77),13.02％(22/169)and 18.02％(20/111),respectively.There was no statistically significant difference in the positive rates among different sample types.The predominant CRO-positive organisms detected were Klebsiella pneumoniae in intestinal samples and Pseudomonas aeruginosa in respiratory samples.Among 361 intestinal and respiratory samples tested from 88 patients,plate screening and Xpert Carba screening showed the positive rates of 14.40％(52/361)and 6.37％(23/361),respectively.Analysis of the clinical characteristics of the 31 CRO-posi-tive patients revealed that they were predominantly elderly(average age 69 years),with 51.61％(16/31)having a history of interdepartmental transfers and 48.39％(15/31)having surgerical history.The mechanical ventilation usage rate in the respiratory positive group(58.82％,10/17)was higher than that in the intestinal positive group(0,0/7)and the dual positive group(14.28％,1/7).Compared with Xpert Carba,plate screening had lower screening costs,higher positive rates across different sample types and a broader range of detected bacterial species.CONCLUSIONS The ICU ward is a high-prevalence area for CRO strains,with K.pneumoniae(from in-testinal samples)and P.aeruginosa(from respiratory samples)showing the highest isolation rates.Plate screen-ing boasts lower costs,higher detection rate and broader bacterial species coverage for active screening of CRO strains in the intestinal and respiratory tracts of high-risk ICU patients.

BACKGROUND: As an essential part of health services, rehabilitation is of great significance to improve the health and quality of life of the whole population. Accelerating aging calls for a significant expansion of rehabilitation services in China, but rehabilitation needs remain unclear. We conducted the study to explore the rehabilitation needs in China and project the trend of rehabilitation needs from 2020 to 2034. METHODS: The data of health conditions that might potentially benefit from rehabilitation were obtained from Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to quantify the trends of the age-standardized rates. Projections of rehabilitation needs were made until 2034 using Bayesian age-period-cohort analysis (BAPC). RESULTS: Approximately 460 million persons (33.3% of the total population) need rehabilitation in China, contributing to 63 million years lived with disabilities (YLDs) in 2019. The number of prevalent cases that need rehabilitation increased from around 268 (95% uncertainty interval [UI]: 257-282) million in 1990 to almost 460 (95% UI: 443-479) million in 2019, representing an increase of 71.3%. The highest contribution to the need for rehabilitation was musculoskeletal disorders with about 322 (95% UI: 302-343) million persons in seven aggregate disease and injury categories, and hearing loss with over 95 (95% UI: 84-107) million people among 25 health conditions. Based on the projection results, there will be almost 636 million people (45% of the total population) needing rehabilitation services in China by 2034, representing an increase of 38.3%. The rehabilitation needs of neoplasms, cardiovascular diseases, and neurological disorders are expected to increase significantly from 2019 to 2034, with increases of 102.3%, 88.8% and 73.2%, respectively. CONCLUSIONS The need for rehabilitation in China substantially increased over the last 30 years. It is predicted that over two in five people will require rehabilitation by 2034, thus suggesting the need to develop rehabilitation services that meet individuals' rehabilitation needs.

Objective:To investigate the knowledge, attitudes, practices (KAP), and demands of medical staff in family physician teams regarding the application of artificial intelligence (AI) in contracted services, and to analyze the influencing factors.Methods:A cross-sectional study was conducted from June to July 2023. A total of 602 medical staff members from family physician teams in Shanghai Minhang District were selected as subjects. Data on demographics (age, gender, institution, position, education, work experience, household registration, professional title, marital status, fertility status) and KAP/demand regarding AI application in contracted services were collected using a self-designed questionnaire. Intergroup differences were analyzed. Multiple stepwise linear regression was employed to identify the main factors influencing AI application demand.Results:Among the 602 participants, 484 (80.4%) were aged 30-49 years, 466 (77.40%) were females, 559 (92.9%) held a bachelor′s degree or higher, and 505 (83.9%) had intermediate or senior professional titles. The awareness rate for knowledge, positive attitude rate, and practice implementation rate regarding AI application were 47.2% (284/602), 73.1% (440/602), and 32.1% (193/602), respectively. The mean scores for knowledge, attitude, and practice were 15.72±3.40, 18.34±3.41, and 14.60±3.89, respectively. Significant differences were found among the items within each KAP dimension (knowledge: F=7.688, P<0.001; attitude: F=5.106, P<0.001; practice: F=6.763, P<0.001). Within knowledge, item K3 (awareness of intelligent elderly monitoring devices) scored lowest (3.00±0.79), differing significantly from K1, K2, K4, and K5 (all P<0.05). Within attitude, item A5 (willingness to fully trust AI′s accuracy and convenience in contracted services) scored lowest (3.57±0.75), differing significantly from A3 and A4 (all P<0.05). Within practice, item P3 (increasing reliance on AI in daily contracted services) scored lowest (2.79±0.93), differing significantly from P1 and P2 (all P<0.05). KAP scores differed significantly across demographic subgroups. Knowledge scores differed significantly by age, gender, and marital status (all P<0.05). Attitude scores differed significantly by gender, household registration, and fertility status (all P<0.05). Practice scores differed significantly by gender, position, and marital status (all P<0.05). Regarding demand, the most frequently selected areas were follow-up services (28.74%, 173/602), data management (26.25%, 158/602), and data collection (25.42%, 153/602). Univariate analysis identified age, gender, education, professional title, fertility status, and KAP scores as significant factors influencing AI application demand (all P<0.05). Multiple stepwise linear regression revealed that older age ( t=3.905, P<0.001), female gender ( t=3.548, P<0.001), and higher practice scores ( t=-3.044, P=0.002) were significant predictors of greater AI application demand. Conclusions:Significant variations exist in the KAP levels regarding AI application among family physician team members. Gender, age, and practice behavior significantly influence demand. Tailored strategies for different subgroups, coupled with timely targeted training and practical exercises, are recommended to enhance the effective and widespread adoption of AI technology in family physician contracted services.

Objective:To investigate the current situation of key endemic disease prevention and control in Shanxi Province, and provide a scientific basis for further strengthening the implementation of prevention and control measures.Methods:In 2021, monitoring of key endemic disease prevention and control projects in Shanxi Province was carried out in accordance with the current national monitoring plans for iodine deficiency disorders and water source high iodine areas, for endemic fluorosis, endemic arsenic poisoning, Kashin-Beck disease, and Keshan disease. The effect of prevention and control measures was evaluated in accordance with the "Evaluation Measures for Key Endemic Disease Control and Elimination (2019 Edition)". Patient management services and treatment subsidy projects were carried out in accordance with the "Management Service Standards for Endemic Disease Patients" and the "Management Measures for Treatment of Endemic Disease Patients".Results:All 117 counties (cities, districts, hereinafter referred to as counties) in Shanxi Province had reached the national elimination standards for iodine deficiency disorders, and the overall iodine nutrition of the population was generally suitable. However, the consumption rate of qualified iodine salt in 8 counties was ≤90%, and the iodine nutrition of pregnant women in 13 counties was insufficient. The water improvement rate in 295 villages in 12 counties across the province with high water iodine level was 80.68% (238/295), and the proportion of villages with qualified water iodine after water improvement was 38.31% (113/295). The prevention and control measures of 93.55% (58/62) of the counties in the province with endemic fluorosis caused through drinking water reached the national control standards. Totally 20 counties ravaged by coal-burning borne endemic fluorosis, 16 counties ravaged by drinking water borne endemic arsenicosis (high arsenic areas), 35 counties ravaged by Kashin-Beck disease, and 11 counties ravaged by Keshan disease met the national elimination standards. In 2021, 11 197 patients with endemic diseases were followed up and managed in Shanxi Province, and drug treatment programs were carried out on 3 413 patients with skeletal fluorosis, 2 088 patients with Kashin-Beck disease, and 10 patients with chronic Keshan disease.Conclusions:The overall prevention and control of key endemic diseases in Shanxi Province remains under control or elimination. However, the water improvement in some drinking water borne endemic fluorosis areas still needs to be further strengthened. Measures for water improvement and supply of non-iodized salt in water source high iodine areas still need to be coordinated and promoted. Key endemic disease patients in Shanxi Province have basically achieved standardized management.

Objective:To explore the influence of substance abuse history on anxiety and depression of male prisoners during their imprisonment, and its relationship with violent behavior.Methods:A questionnaire survey was conducted among 1 455 prisoners from October to November 2019.Self-administered personal substance abuse history questionnaires were used to collect the information on substance abuse (alcohol, tobacco, and drug use). The generalized anxiety scale (GAD-7) and patient health questionnaire (PHQ-9) were used to investigate anxiety and depression.All subjects were divided into substance abuse group ( n=871) and non substance abuse group ( n=584) according to whether they had a history of substance abuse or not.SPSS 21.0 software was used for statistical analysis.The statistical methods were t-test, chi square test and Logistic regression analysis. Results:(1)The scores of GAD-7 ((4.95±5.88) vs (3.35±5.33), t=-5.407, P<0.01) and PHQ-9 ((6.69±6.50) vs (4.48±5.73), t=-6.821, P<0.01) scales in the substance abuse group were higher than those in the no-substance abuse group.(2)Somatic disease( β=0.700, OR=2.014, 95% CI=1.599-2.538, P<0.05), history of alcohol abuse( β=0.434, OR=1.543, 95% CI=1.176-2.025, P<0.05), history of tobacco abuse( β=0.387, OR=1.473, 95% CI=1.154-1.880, P<0.05), age ≤ 45( β=0.372, OR=1.450, 95% CI=1.118-1.881, P<0.05) were the risk factors of anxiety among prisoners.Somatic disease( β=0.686, OR=1.986, 95% CI=1.581-2.496, P<0.05), history of tobacco abuse( β=0.488, OR=1.629, 95% CI=1.286-2.063, P<0.05), age ≤ 45( β=0.484, OR=1.622, 95% CI=1.260-2.089, P<0.05), history of alcohol abuse( β=0.344, OR=1.410, 95% CI=1.073-1.854, P<0.05) were the risk factors of depression among prisoners.(3) Years of education ≤ 9 years( β=0.900, OR=2.459, 95% CI=1.855-3.261, P<0.05), age ≤ 45( β=0.788, OR=2.199, 95% CI=1.690~2.860, P<0.05), unmarried( β=0.683, OR=1.980, 95% CI=1.421-2.759, P<0.05), history of alcohol abuse( β=0.308, OR=1.361, 95% CI=1.053-1.758, P<0.05), history of drug abuse( β=0.557, OR=1.745, 95% CI=1.055-2.885, P<0.05) were risk factors for violent behavior of prisoners. Conclusion:The history of substance abuse may be a risk factor for anxiety and depression of prisoners during their imprisonment.Alcohol and drug abuse are both factors influencing the occurrence of violent behavior.

ObjectiveTo investigate the effect of Glycyrrhizae Radix et Rhizoma （GR）-containing serum on lipopolysaccharide （LPS）-induced inflammation in human colon epithelial adenocarcinoma cells （Caco2） based on inhibition of ferroptosis by the nuclear factor erythroid 2-related factor 2 （Nrf2）/heme oxygenase-1 （HO-1） pathway. MethodCaco2 cells were divided into a normal group， a model group （LPS， 200 μg·L^-1）， low-， medium-， and high-dose GR-containing serum groups （5%， 10%， 20%）， and a ferroptosis inhibitor group （3-amino-4-cyclohexylamino-benzoic acid ethyl ester， Fer-1， 10 μmol·L^-1）. The cells in the normal group were cultured normally， while those in other groups underwent the induction of an inflammation model. The cells in the low-， medium-， and high-dose GR-containing serum groups were treated with 5%， 10%， and 20% GR-containing serum for 24 hours， respectively， and the cells in the ferroptosis inhibitor group were treated with Fer-1 for 24 hours. Transmission electron microscopy was used to observe mitochondrial morphology in each group. Flow cytometry was used to detect intracellular Fe²⁺ levels. Microplate assays were performed to measure superoxide dismutase （SOD） activity， malondialdehyde （MDA） and glutathione peroxidase （GSH-Px） levels. Enzyme-linked immunosorbent assay （ELISA） was used to measure interleukin-1β （IL-1β）， IL-6， IL-10， and tumor necrosis factor-α （TNF-α） levels. Western blot was used to measure the expression levels of Nrf2， HO-1， ferritin heavy chain 1 （FTH1）， and glutathione peroxidase 4 （GSH-Px4） proteins. Small interfering RNA （siRNA） was used to investigate the role of Nrf2 in ferroptosis regulation. The cells after interference were divided into a negative control （NC） group， a Si-Nrf2 group， a GR-containing serum （20%） + Si-Nrf2 group， and a GR-containing serum （20%） + NC group. Microplate assays were performed to measure MDA， SOD， and GSH-Px levels， and Western blot was used to measure the expression levels of Nrf2， HO-1， FTH1， and GSH-Px4 proteins. ResultCompared with the normal group， the model group showed mitochondrial contraction， increased mitochondrial membrane thickness， and smaller mitochondrial morphology， increased Fe²⁺ content （P<0.01）， blunted SOD activity （P<0.01）， decreased GSH-Px expression （P<0.01）， increased MDA content （P<0.01）， reduced expression levels of Nrf2 and HO-1 （P<0.05）， reduced FTH1 expression （P<0.01）， and down-regulated GSH-Px4 expression （P<0.01）. In the GR-containing serum groups， the medium- and high-dose groups showed a significant decrease in Fe²⁺ content （P<0.01）， potentiated SOD and GSH-Px activities （P<0.01）， and decreased MDA levels （P<0.01）. The high-dose group showed a significant increase in Nrf2 expression （P<0.05）， and the medium-dose group showed increased expression of HO-1 and GSH-Px4 proteins （P<0.05）. The expression levels of FTH1 significantly increased in the low-， medium-， and high-dose groups （P<0.01）. The study on mechanism revealed that compared with the NC group， the cells transfected with Nrf2 siRNA showed increased MDA content （P<0.01）， blunted SOD activity （P<0.01）， decreased GSH-Px activity （P<0.01）， decreased expression of Nrf2 and HO-1 （P<0.01）， and reduced levels of FTH1 and GSH-Px4 proteins （P<0.01）. Compared with the Si-Nrf2 group， the cells treated with GR-containing serum showed a decrease in MDA content （P<0.01）， an increase in SOD activity （P<0.01）， an increase in GSH-Px activity （P<0.01）， increased expression of Nrf2 and FTH1 proteins （P<0.05）， and higher expression levels of HO-1 and GSH-Px4 proteins （P<0.01）. ConclusionGR-containing serum can reduce the inflammatory cytokines and oxidative stress levels in LPS-induced Caco2 cells. Its mechanism is related to the promotion of Nrf2/HO-1 signaling pathway expression， alleviating intracellular lipid peroxidation and inhibiting ferroptosis.

The hazards of water-borne iodine excess is a relatively serious public health problem in China. The government has made great progress in prevention and controlling of the hazards of water-borne iodine excess through measures such as supplying non-iodized salt and implementing measures such as improving water quality to decrease iodine. However, there is a lack of corresponding evaluation criteria for measuring the implementation level and effectiveness of prevention and control measures, which urgently needs to be addressed. This article explores the technical indicators for establishing control standards for water source high iodine hazards in China through a review and analysis of relevant laws and regulations, normative documents, standards, and research progress in the field of high iodine prevention and control at home and abroad. It is recommended that administrative villages be used as units to evaluate the control status of water source high iodine hazards; after water improvement and iodine reduction, the iodine content of residents' drinking water should be ≤100 μg/L; meanwhile, the median urinary iodine for school-age children should be between 100 and < 300 μg/L, thyroid enlargement rate should be less than 5%.
