Aim To investigate the effects of high glu-cose on cholesterol metabolism in renal tubular cells and the intervention of the anthocyanins. Methods HK-2 cells were grown in the DMEM medium supple-mented with 10% FBS and were divided into 5 groups:normal glucose group, high glucose group, mannitol group, C3G group and Cy group. Effect of anthocya-nins on cell viability was detected with MTT, and cho-lesterol accumulation was detected with Amplex Red Cholesterol Assay kit and Filipin staining. Expression of ABCA1 was detected with RT-qPCR and Western Blot. Results In compared with control groups, HG significantly promoted cholesterol mass inside the cell and decreased the cholesterol concentration in the me-dium after treatment for 24 h or 48 h. The levels of mRNA and protein of ABCA1 were detected with RT-qPCR and Western blot, and both were decreased in the presence of HG. Whereas treatment with C3G and Cy markedly attenuated HG-induced cholesterol mass inside the cell by up-regulating the expression of AB-CA1. Conclusions High glucose can reduce the ex-pressions of the ABCA1, and then decrease cholesterol efflux and increase the cholesterol accumulation in HK-2 cells. Anthocyanins can decrease cholesterol accu-mulation by up-regulating the expression of ABCA1.

The 29th European Congress on Obesity(ECO) was held in Maastricht, Netherlands from May 4 to May 7, 2022. The conference consisted of five sections with a great amount of information: basic science, behavioural and public health, childhood and adolescent obesity, management and intervention, and metabolic surgery, with a total of more than 80 special reports. We summarized the epidemiological investigation, diagnosis, complications and management of obesity, aiming to provide reference information for the comprehensive management of obesity in China.

Objective: To observe the long-term efficacy and safety of autologous hematopoietic stem cell transplantation (AHSCT) for systemic sclerosis (SSc) patients. Methods: Between May 2007 and June 2009,4 patients with SSc were enrolled in the study. Peripheral blood stem cells were mobilized with cyclopho-sphamide (CTX) followed by granulocyte colony stimulating factor (G-CSF). Conditioning was performed with i.v. cyclophosphamide 50 mg·kg^-1·d^-1 for 4 days. The results of the modified Rodnan skin score (mRSS), thoracic high-resolution computer tomography and pulmonary function were collected after transplantation. Results: There was an improvement in mRSS, lung function and HRCT in the six months after AHSCT. Within six month to one year after transplantation, one patient had sustained and two patients recurred. After active treatments two patients were improved again. During the follow-up of 8.7 (4.1-9.8) years, three patients were stable and one patient died. Infection and hepatic function injury were the major complications. There was not transplant-related mortality. Conclusion AHSCT with CTX as a pre-conditioning regimen is safe and effective for SSc. The efficacy for patients with short course, rapid progress and edema is significant. However, long-term efficacy is poor, and long-term maintenance treatment is needed.

Objective To retrieve and evaluate the evidences for fall prevention in elderly inpatients, and to summary the best evidence. MethodsGuidelines, evidence summaries and systematic reviews related to fall prevention of elderly patients were retrieved in guideline websites and databases by computer from building database to 31st December 2018. Literatures' quality evaluation and evidence grading were carried out with the Chinese version of appraisal of guidelines for research and evaluationⅡ (AGREEⅡ), "2016 Joanna Briggs Institute quality assessment tool on validity evaluation of systematic reviews" and "2014 Joanna Briggs Institute quality level of evidence and grade of recommendation system". ResultsA total of 6 documents were included with 3 guidelines and 3 systematic reviews. Based on evaluation and results extracted, 14 items of the best evidences on fall prevention were summarized in two parts including assessment and prevention, and in 6 aspects involving the medication, facility, environment, functional training, informational support and multifactorial intervention. ConclusionsMedical staff should guide patients to take standardized fall preventive measures to guarantee the safety of patients based on evidence-based medicine.

Objective To analyze the influencing factors of disaster resilience in medical rescue workers,to construct a prediction model for the low-level risk of disaster resilience in medical rescue workers,and to verify the predictive effect of the model.Methods Using the convenience sampling method and the snowball method,1 037 medical rescue workers who participated in disaster rescue in 18 provinces(autonomous regions and municipalities)were selected as the participants from May to July 2022.Online questionnaire surveys were conducted using general information questionnaires,disaster resilience measuring tools for healthcare rescuers,the Mindful Attention Awareness Scale,the Simple Coping Style Questionnaire and the Depression-Anxiety-Stress Scale.Univariate and multivariate logistic regression analyses were used to determine the independent influencing factors for the low level of disaster resilience of medical rescue workers.A risk prediction model was constructed,and a nomogram chart was drawn.The model's effectiveness was evaluated using the receiver operating characteristic curve(ROC)and calibration curve.The Bootstrap method was applied for internal validation.Results The logistic regression analysis showed that per capita monthly income of households,whether to participate in on-site disaster rescue,positive coping,mindfulness level,and adequacy of rescue supplies were independent influencing factors for the disaster resilience of medical rescue workers(P＜0.05).The predictive formula for the low-level risk of disaster resilience in medical rescue workers was established as follows:Logit(P)=8.741-0.381 x per capita monthly income of households-0.891 x whether to participate in on-site disaster rescue-2.544 x positive coping-0.020 x mindfulness level-0.222 x adequacy of rescue supplies.The area under the ROC curve was 0.823,and the optimal critical value was 0.353.The sensitivity and specificity were 79.12％and 71.43％,respectively.The Hosmer-Lemeshow test showed that x2=12.250(P=0.140),and the predicted curve fitted well with the ideal curve.The external validation showed that the sensitivity and specificity of the model were 75.00％and 66.39％,respectively,and the overall accuracy was 69.95％.Conclusion The prediction model in this study has sound predictive effects and can provide references and guidance for managers to select,recruit,and train medical rescue workers.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.
