In order to standardize humanistic caring services for patients in the operating room of medical institutions, improve the comprehensive service level of the operating room, and enhance the surgical experience of patients, the Chinese Association for Life Care released the group standard " Humanistic Caring Management Standards for Patients in the Operating Room" in December 2023. This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Objective To investigate the effect of perindopril on the nicotinamide adenine dinucleotide phosphate(NADPH)oxidase 4(NOX4)/NOD-like receptor protein 3(NLRP3)signaling pathway in rat liver fibrosis induced by thioacetamide(TAA).Methods Thirty-two SD rats were randomly divided into the blank group,the model group(TAA 200 mg/kg,twice a week for 6 weeks)and the low/high dose group(TAA+perindopril 2/8 mg/kg),with 8 rats in each group.Two weeks after modeling,the administration group was given the corresponding dose of perindopril by gavage(for 4 weeks).At the end of the 6th week,liver pathological sections were used to observe pathological changes of liver tissue and degrees of fibrosis and inflammation.The biochemical analyzer was used to detect alanine aminotransferase(ALT)and aspartate aminotransferase(AST).Enzyme-linked immunosorbent assay(ELISA)was used to detect NLRP3 and IL-1β.Immunohistochemistry was used to detect NOX4,NLRP3,Caspase-1,IL-1β protein and α-smooth muscle agonist protein(α-SMA).Results Compared with the blank group,liver collagen fibers were significantly proliferated in the model group,a large number of inflammatory cells infiltrated,and serum levels of ALT and AST,as well as NLRP3 and IL-1β in rats were significantly increased.The average optical density values of positive proteins such as NOX4,NLRP3,Caspase-1,IL-1β and α-SMA in rat liver tissue increased significantly(P<0.05).Compared with the model group,the proliferation of collagen fibers and inflammatory infiltration were significantly reduced in both the low-dose and high-dose groups,and serum levels of ALT and AST,NLRP3 and IL-1β in rats were significantly decreased.The average optical density values of positive proteins such as NOX4,NLRP3,Caspase-1,IL-1β and α-SMA in rat liver tissue decreased significantly(P<0.05).Moreover,the degree of liver fibrosis reduction in rats was better in the high-dose group than that in the low-dose group.Conclusion Perindopril may regulate the NLRP3 signaling pathway by inhibiting the expression of NOX4,thereby reducing oxidative stress damage and inflammatory responses and thus delaying the process of liver fibrosis.

BACKGROUND:Hyperhomocysteinemia is closely related to the function of islet β cells,but its specific molecular mechanism is not fully understood. OBJECTIVE:To investigate the role of N6 methyltransferase-like 3(METTL3)in homocysteine(Hcy)-induced autophagy of mouse islet β cells. METHODS:The 3rd and 4th generation mouse islet β cells were taken for the experiment.(1)Cell modeling and grouping:cells in control group were not treated with Hcy,while those in homocysteine group were treated with 100 μmol/L Hcy for 48 hours.(2)The mouse islet β-cells were transfected with the plasmids overexpressing Ad-METTL3 and si-METTL3 according to the instructions of LipofectamineTM 2000.Three different interfering fragments were designed,and the one with the best interfering efficiency was verified and screened by PCR.(3)After transfection,the cells were divided into control group,Hcy group,Ad-NC(negative control)+Hcy group,Ad-METTL3+Hcy group,si-NC(negative control)+Hcy group and si-METTL3+Hcy group.(4)qRT-PCR and western blot were used to detect the expression levels of METTL3 and autophagy-related proteins LC3Ⅱ/Ⅰ and p62 in cells.Insulin level was determined by ELISA to evaluate insulin secretion capacity of islet cells.Autophagy-related proteins and insulin level were detected after overexpression and interference with METTL3. RESULTS AND CONCLUSION:Compared with the control group,the expression level of LC3Ⅱ/Ⅰ was increased(P＜0.05),the expression of p62 was significantly reduced(P＜0.05),and the insulin secretion capacity was significantly decreased(P＜0.05)in the Hcy group.Compared with the control group,the protein and mRNA levels of METTL3 were reduced in the Hcy group(P＜0.05).After METTL3 silencing in islet β cells,Hcy further upregulated the expression of LC3Ⅱ/Ⅰ(P＜0.05),significantly dowregulated the expression of p62(P＜0.05),and increased the insulin level(P＜0.05).After overexpression of METTL3,Hcy significantly decreased the LC3Ⅱ/Ⅰ expression and increased the p62 expression in islet β cells(P＜0.05).To conclude,METTL3 is involved in the Hcy-induced autophagy regulation of islet β cells and plays a role in the regulation of insulin secretion.

Objective:To understand the influence of unhealthy lifestyle on diabetic dyslipidemia and the key influencing factors in occupational population and provided scientific evidence for the prevention of diabetic dyslipidemia.Methods:Based on baseline data and follow-up data of Southwest Occupational Population Cohort from China Railway Chengdu Group Co., Ltd. during 2021. Diabetic dyslipidemia was defined as diabetes plus one or more forms of dyslipidemia, and unhealthy lifestyle factors included smoking, alcohol consumption, unhealthy dietary patterns, low physical activity, and abnormal BMI. Multivariate logistic regression model was used to analyze the relationship between unhealthy lifestyle scores and diabetic dyslipidemia, network analysis was used to find and explore the key lifestyles influencing glycolipid metabolism.Results:A total of 25 631 subjects were included. People with unhealthy lifestyle score 2 and 3 were 1.93 (95% CI: 1.31-2.86) times and 2.37 (95% CI: 1.60-3.50) times more likely to have diabetes with ≥1 forms of dyslipidemia than those with scores of 0; People with unhealthy lifestyle score 1, 2 and 3 were 1.98 (95% CI: 1.08-3.61) times, 2.87 (95% CI: 1.60-5.14) times and 3.95 (95% CI: 2.22-7.06) times more likely to have diabetes with ≥2 forms of dyslipidemia than those with score 0. Network analysis found that abnormal BMI and HDL-C were the "bridge nodes" that link unhealthy lifestyles with diabetic dyslipidemia. Conclusion:The higher the score of unhealthy lifestyle, the higher the risk for diabetic dyslipidemia, abnormal BMI and HDL-C are key factors influencing the association between unhealthy lifestyle and diabetic dyslipidemia.

Objective:To understand the relationship between unhealthy lifestyle and hyperuricemia, as well as the modification effects of hypertension and dyslipidemia in occupational population and provide a theoretical basis for the prevention of hyperuricemia.Methods:A cross-sectional survey design was adopted, based on baseline data from the Southwest Occupational Population Cohort from China Railway Chengdu Group Co., Ltd., which included the population in 28 prefectures from Sichuan Province and Guizhou Province, and 33 districts (counties) from Chongqing Municipality between October and December 2021. This study collected the information about the demographics characteristics, lifestyles, and prevalence of chronic non-communicable diseases of the study subjects through questionnaire, physical measurement and laboratory biochemical test. The unhealthy lifestyle score was scored based on smoking, alcohol consumption, dietary patterns, physical activity, and low weight or overweight, with higher scores being associated with more unhealthy lifestyles. The multivariate logistic regression model was used to analyze the relationship between unhealthy lifestyle score, smoking, alcohol consumption, other factors and hyperuricemia, and the stratified analysis was used to explore the modification effect of hypertension and other diseases on the relationship between unhealthy lifestyle and hyperuricemia.Results:A total of 11 748 participants were included in this study, the prevalence of hyperuricemia was 34.4%. Multivariate logistic regression model showed that current/previous smoking, current/previous alcohol consumption and BMI abnormality were risk factors for hyperuricemia, and the unhealthy lifestyle score showed a "cumulative" effect on the risk for hyperuricemia, with higher score increasing the risk of hyperuricemia, and the OR increased from 1.64 (95% CI: 1.34-2.00) to 2.89 (95% CI: 2.39-3.50). Stratified analysis showed that unhealthy lifestyles had a greater impact on the risk for hyperuricemia in people with hypertension and dyslipidemia. Conclusions:The coexistence of multiple unhealthy lifestyles might increase the risk of hyperuricemia, and this effect was stronger in participants with hypertension and dyslipidemia. Timely correction of unhealthy lifestyles, and control of hypertension and dyslipidemia might reduce the risk for hyperuricemia.

Objective:To explore the clinical phenotype and genetic etiology for a Chinese pedigree affected with Autosomal dominant polycystic kidney disease (ADPKD).Methods:A pedigree with ADPKD diagnosed at the Department of Gynaecology of the First Affiliated Hospital of Zhengzhou University in December 2020 was selected as the study subject. Clinical data of the pedigree was collected, and whole exome sequencing (WES) was carried out for the proband. Candidate variants were verified by Sanger sequencing of the proband and her relatives. This study was approved by the First Affiliated Hospital of Zhengzhou University (Ethics No. KS-2018-KY-36).Results:Fetal ultrasonography showed increased volume and parenchymal echogenicity in both kidneys. The fetus was found to harbor c. 11098C>T (p.R3700C) and c.11039T>C (p.F3680S) compound heterozygous variants of the PKD1 gene, which were respectively inherited from its mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be likely pathogenic (PM1+ PM2_Supporting+ PP3). Conclusion:The c. 11098C>T (p.R3700C) and c. 11039T>C (p.F3680S) compound heterozygous variants of the PKD1 gene probably underlay the ADPKD in the fetus. Above finding has provided guidance for the genetic counseling and prenatal diagnosis for this pedigree.

Objective:To analyze the detection strategy and basic detection situation of markers of infectious diseases transmitted by transfusion in blood testing laboratories of blood stations in China.Methods:Based on the data of practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021, the data on the testing strategies and the basic detection information of the markers for the transmission of infectious diseases through transfusion in the member laboratories of the practice comparison working party of Blood Stations in Mainland of China from 2017 to 2021 were collected, and the situation of the selection for testing markers, testing strategy and the testing method and other relevant aspects were sorted out and analyzed by charts.Results:The selection of the testing markers was consistent, but HTLV testing item was added in some member laboratories. The detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously was adopted in 47 member blood stations; 3) NAT method was dominated by mini pool-NAT in member laboratories. The number of members adopting mini-pools of 8 (MP8)-NAT decreased from 17 in 2017 to 14 in 2021, while the number of members adopting mini-pools of 6 (MP6)-NAT increased from 13 in 2017 to 22 in 2021; Roche NAT system accounted for the largest proportion.Conclusions:In order to ensure blood safety and avoid missing detection, the blood stations still adopt the detection strategy of using two ELISA reagents and one nucleic acid testing (NAT) reagent simultaneously; Meanwhile, in order to increase the NAT positive rate, the proportion of mini pool-NAT mainly decreased year by year despite its dominating role, while the proportion of individual donation-NAT increased year by year; NAT method is transiting from mini-pools of 8 (MP8) to mini-pools of 6 (MP6); The proportion of imported NAT system used in NAT laboratory is relatively large.
