Background::The association and its population heterogeneities between low-density lipoprotein cholesterol (LDL-C) and all-cause and cardiovascular mortality remain unknown. We aimed to examine the dose-dependent associations of LDL-C levels with specific types of cardiovascular disease (CVD) mortality and heterogeneities in the associations among different population subgroups.Methods::A total of 2,968,462 participants aged 35-75 years from China Health Evaluation And risk Reduction through nationwide Teamwork (ChinaHEART) (2014-2019) were included. Cox proportional hazard models and Fine-Gray subdistribution hazard models were used to estimate associations between LDL-C categories (<70.0, 70.0-99.9, 100.0-129.9 [reference group], 130.0-159.9, 160.0-189.9, and ≥190.0 mg/dL) and all-cause and cause-specific mortality.Results::During a median follow-up of 3.7 years, 57,391 and 23,241 deaths from all-cause and overall CVD were documented. We observed J-shaped associations between LDL-C and death from all-cause, overall CVD, coronary heart disease (CHD), and ischemic stroke, and an L-shaped association between LDL-C and hemorrhagic stroke (HS) mortality ( P for non-linearity <0.001). Compared with the reference group (100.0-129.9 mg/dL), very low LDL-C levels (<70.0 mg/dL) were significantly associated with increased risk of overall CVD (hazard ratio [HR]: 1.10, 95% confidence interval [CI]: 1.06-1.14) and HS mortality (HR: 1.37, 95% CI: 1.29-1.45). Very high LDL-C levels (≥190.0 mg/dL) were associated with increased risk of overall CVD (HR: 1.51, 95% CI: 1.40-1.62) and CHD mortality (HR: 2.08, 95% CI: 1.92-2.24). The stronger associations of very low LDL-C with risk of CVD mortality were observed in individuals with older age, low or normal body mass index, low or moderate 10-year atherosclerotic CVD risk, and those without diagnosed CVD or taking statins. Stronger associations between very high LDL-C levels and all-cause and CVD mortality were observed in younger people. Conclusions::People with very low LDL-C had a higher risk of all-cause, CVD, and HS mortality; those with very high LDL-C had a higher risk of all-cause, CVD, and CHD mortality. On the basis of our findings, comprehensive health assessment is needed to evaluate cardiovascular risk and implement appropriate lipid-lowering therapy for people with very low LDL-C.

Objective:To construct an interactive health care participation program for patients undergoing lower limb bone transport based on the interactive patient participation safety theory framework and the Patient Health Engagement model.Methods:From August to November 2022, through literature review and interviews with patients undergoing lower limb bone transport, a preliminary draft of the interactive health care participation program was developed based on the interactive patient participation safety theory framework and the Patient Health Engagement model. The Delphi method was used to conduct two rounds of consultations with 25 experts to screen and revise the program items.Results:The expert positive coefficients for the two rounds of expert consultations were 92.00% (23/25) and 100.00% (23/23). The authority coefficient was 0.913, and the Kendall's W coefficients for consistency were 0.127 and 0.140 ( P<0.01).

Conclusions:The interactive health care participation program for patients undergoing lower limb bone transport constructed in this study is both scientific and practical, can provide a theoretical basis and practical guidance for patient engagement in health care.

Objective To investigate the current state of quality management on intravenous therapy in secondary and tertiary hospitals in China.This study aims to provide a reference for the development of relevant policies,promoting the professionalization,standardization,and homogenization of intravenous therapy.Methods By a convenience sampling method,intravenous therapy nursing managers from secondary and tertiary hospitals in 31 provinces,autonomous regions,and municipalities were selected as survey participants in November 2023.A self-designed questionnaire was used for the survey.Results A total of 2 129 questionnaires were collected,of which 1,926 were valid,resulting in a response rate of 90.47％.Among the 1926 hospitals,1 733(89.98％)had established quality evaluation standards for intravenous therapy,and 1 734(90.03％)conducted regular quality inspections for intravenous therapy or peripherally inserted central catheter(PICC)insertion and maintenance.Additionally,1 604 hospitals(83.28％)had established protocols for handling and reporting intravenous therapy or PICC-related complications,and 1 574 hospitals(81.72％)regularly collected and analyzed data related to intravenous therapy or PICC insertion and maintenance.Moreover,371 hospitals(19.26％)had implemented intravenous therapy information management systems.Regarding various types of intravenous therapy documents,the highest rate of document types was informed consent forms,with a compliance rate of over 80.00％,followed by insertion records and catheter maintenance records,respectively.The lowest rate was complication management records,with a compliance rate of less than 50.00％.For catheter maintenance protocols,the highest compliance rate was for maintenance procedures,at over 85.00％,followed by insertion procedures.Except for PICCs,the compliance rate for establishing catheter removal and complication management procedures for other types of catheters was less than 65.00％.In terms of quality management of intravenous therapy,there are significant differences between secondary and tertiary hospitals.Conclusion The quality evaluation standards for intravenous therapy are relatively comprehensive,but the informatization of intravenous therapy quality management is still underdeveloped.Furthermore,there is a need to further standardize the documentation and procedures related to intravenous therapy,and there are differences in the level of intravenous therapy management among hospitals of different levels.

Objective:To develop a deep learning model based on multimodal data for glaucoma diagnosis and severity assessment.Methods:A diagnostic test was conducted.A total of 145 normal eyes from 86 participants and 507 eyes with primary open-angle glaucoma from 314 participants were collected at the First Affiliated Hospital of Kunming Medical University from June to December in 2023.Fundus photographs and visual field data were obtained, and glaucoma eyes were divided into three groups based on the mean deviation value of the visual field, namely mild group (154 eyes), moderate group (113 eyes), and severe group (240 eyes).Three convolutional neural network (CNN) models, including DenseNet 121, ResNet 50 and VGG 19, were used to build an artificial intelligence (AI) model.The impact of single-modal and multimodal data on the classification results was evaluated, and the most appropriate CNN network architecture for multimodal data was identified.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of The First Affiliated Hospital of Kunming Medical University (No.2023L93).Written informed consent was obtained from each subject.Results:A total of 652 eyes had both fundus photographs and visual field test results.Images were randomly assigned to training and test datasets in a 4∶1 ratio by using computer random number method.AI models built with different CNN models showed high accuracy, with DenseNet 121 outperforming ResNet 50 and VGG 19 on various effectiveness measures.In the single-modal algorithm using fundus photographs, single-modal algorithm using visual field tests, and multimodal algorithm combining fundus photographs and visual field data, the area under the curve for early glaucoma detection was 0.87, 0.93 and 0.95, respectively.Conclusions:The use of multimodal data enables the development of a highly accurate tool for the glaucoma diagnosis and severity grading.

Purpose To evaluate the value of MRI T1 mapping combined with biliary tract paravertebral muscle signal intensity ratio in liver function.Materials and Methods A total of 72 patients with Gd-EOB-DTPA enhanced MRI were prospectively collected in Beijing Friendship Hospital from August 2020 to February 2022 and divided into three groups according to Child-Pugh classification of liver function:22 patients in normal liver function group,35 patients in grade A group and 15 patients in grade B+C group.The T1 mapping sequence was scanned in all patients before and 20 min after enhancement to measure the pre-enhancement and post-enhancement(T1post)T1 relaxation time of liver parenchyma,and the reduction rate of liver T1 relaxation time(ΔT1)was calculated.Biliary tract signal and paravertebral muscle signal were measured on hepatobiliary stage images,and biliary tract paravertebral muscle signal intensity ratio(SIR)was calculated.The consistency of measurement results among physicians was evaluated.The correlation between each index and liver function grade was observed.The differences among different groups were compared.The diagnostic efficiency of each image index were evaluated.Results T1post was positively correlated with liver function grade(r=0.683,P<0.001),and it increased gradually with the severity of liver function impairment.ΔT1,SIR,SIR×ΔT1 were negatively correlated with liver function grade(r=-0.764,-0.729,-0.826,all P<0.001),and gradually decreased with the severity of liver function impairment.T1post,ΔT1,SIR,SIR×ΔT1 had statistical significance in liver function classification among all groups(F=27.491,55.782,48.410,46.809,all P<0.05).In pairwise comparison,the differences of each index were also statistically significant(P<0.05).The best diagnostic efficacy of each index was SIR×ΔT1,and the area under the curve of normal liver function group and cirrhosis group,grade A group and grade B+C group were 0.915 and 0.984,respectively.Conclusion T1post,ΔT1,SIR and SIR×ΔT1 are strongly correlated with Child-Pugh grade of liver function.SIR×ΔT1 can be used as an imaging index for quantitative evaluation of liver function.

OBJECTIVE:Knee adduction moment and knee adduction angular impulse enlargement is the main biomechanical risk factor of knee osteoarthritis.According to the survey,a change in the foot progression angle could effectively change the motion mode of patients with knee osteoarthritis.However,the impact of toe-in and toe-out on knee adduction moment and knee adduction angular impulse in young and elderly patients did not reach a consensus.Therefore,this study comprehensively discussed the effect of foot progression angle on knee adduction moment and knee adduction angular impulse in different populations through meta-analysis and provided a reference for the treatment of knee osteoarthritis. METHODS:By June 2022,searches were conducted on Web of Science,EBSCO,PubMed and CNKI databases using"foot progression angle,knee adduction moment,knee adduction angular impulse,gait"as Chinese and English search terms.Self-controlled randomized controlled studies analyzing the effects of toe-in and toe-out on knee adduction moment bimodality and knee adduction angular impulse were included.The cochrane bias risk assessment tool was utilized to make a quality evaluation of the literature.Stata 15.1 software was used for subgroup analysis to determine the effect of foot progression angle on knee adduction moment and knee adduction angular impulse.Meta-regression analysis was used to further determine characteristics of outcome indicators(knee adduction moment,knee adduction angular impulse)changing with foot progression angle. RESULTS:(1)A total of 15 self-control trials and 2 randomized controlled trials(455 subjects)were included in the meta-analysis.All of the included articles were of medium to high quality.(2)The meta-analysis results showed that the toe-in gait could reduce the first peak of knee adduction moment(SMD=-0.380,95%CI:-0.710 to-0.060,P=0.022)and knee adduction angular impulse(SMD=-1.470,95%CI:-2.160 to-0.770,P<0.001)in young patients.The toe-out gait reduced the second peak of knee adduction moment(SMD=-0.720,95%CI:-1.010 to-1.440,P<0.001)in young patients.In addition,toe-in gait could reduce the first peak of knee adduction moment in elder patients(SMD=-0.550,95%CI:-0.800 to-0.300,P<0.001),but increase the second peak knee adduction moment of elderly(SMD=0.280,95%CI:-0.010 to 0.560,P=0.047).The toe-out gait could decrease the second peak knee adduction moment in this population(SMD=-0.510,95%CI:-0.830 to-0.190,P=0.002).(3)Meta-regression showed that the greater the toe-out in elderly patients,the lower the second peak knee adduction moment. CONCLUSION:(1)Toe-in reduced the first peak knee adduction moment and knee adduction angular impulse in young knee osteoarthritis patients aged 18 to 34 years.Since knee adduction moment and knee adduction angular impulse were associated with medial knee loading and knee osteoarthritis incidence,toe-in gait intervention may be a suitable rehabilitation strategy for young patients.(2)Toe-in increased the second peak of knee adduction moment in older knee osteoarthritis patients over 60 years of age,which may exacerbate knee osteoarthritis in this population.However,the second peak of knee adduction moment during walking in this population decreases as the toe-out increases,contributing to a reduction in medial knee loading,suggesting that older patients may consider using toe-out gait during walking.

Brucellosis is a zoonotic infectious disease caused by Brucella infection. So far, animal to animal Brucellosis has not been eradicated, and there is a lack of safe and effective human vaccine. Therefore, "early, combined, sufficient, and full course" drug treatment remains an important strategy in the management of human Brucellosis. The goal of treating brucellosis is to alleviate and shorten the symptom period, reduce complications, relapses, and chronicity. At present, although antibiotic treatment is effective for most patients, there are still some patients who experience treatment failure or later recurrence, so the treatment strategy for brucellosis urgently needs to be optimized. This article elaborates on the treatment principles, clinical treatment status, and future development trends of brucellosis, in order to provide references for optimizing drug treatment methods for brucellosis.

Objective To explore the relationship between preoperative coronary angiography and postoperative acute kidney injury (AKI) in cardiac surgery. Methods The clinical data of patients who underwent coronary angiography within 30 days before cardiac surgery in the First Affiliated Hospital of Xi’an Jiaotong University from January 2015 to April 2019 were retrospectively analyzed. Univariate analysis and multivariate logistic regression analyses were used to explore the relationship between the interval from preoperative coronary angiography to cardiac surgery and postoperative AKI. Results Finally 1 112 patients were collected, including 700 males and 412 females, with a median age of 61 (55, 66) years. The incidence of postoperative AKI was 40.8% (454/1 112), of which grade 2-3 AKI accounted for 11.9%. Multivariate analysis showed that age (OR=1.049, 95%CI 1.022-1.077, P<0.001), body mass index (OR=1.065, 95%CI 1.010-1.123, P=0.020) and time interval between preoperative coronary angiography and cardiac surgery within 24 hours (OR=1.625, 95%CI 1.116-2.364, P=0.011) were independent predictors of postoperative AKI. Patients who underwent coronary angiography within 24 hours before surgery had a 10.6% higher incidence of postoperative AKI compared to those who underwent angiography ≥24 hours before surgery (P=0.004). Patients who underwent valve surgery with or without coronary artery bypass grafting (CABG) had a higher risk of AKI than those who only underwent CABG. The in-hospital stay of patients who developed AKI was 2 days longer than those without AKI. However, undergoing coronary angiography within 24 hours before cardiac surgery did not prolong the length of ICU stay or hospital stay, nor did it increase the risk of death or renal failure after the operation. Conclusion Undergoing coronary angiography within 24 hours before cardiac surgery increases the risk of postoperative AKI.

Objective:To analyze the influencing factors of platinum resistant recurrence in advanced epithelial ovarian cancer(AEOC),establish a nomogram model to predict platinum-resistant recurrence of AEOC,and inter-nally validate it.Methods:The clinicopathological data of 577 AEOC patients who achieved complete remission af-ter initial treatment in the Department of Gynecology,Yunnan Cancer Hospital from June 1,2013 to December 31,2021 were collected.According to whether the platinum free interval(PFI)was less than 6 months,the patients were divided into platinum-resistant recurrence group(130 cases)and non-platinum-resistant group(447 cases,including patients with platinum-sensitive recurrence and no recurrence after 6 months of follow-up).Multivariate Logistic regression analysis was used to screen for the independent risk factors affecting the recurrence of plati-num-resistant patients.Based on the independent risk factors,a nomogram prediction model was established,and Bootstrap method was used for internal verification.The area under the ROC curve(AUC),calibration curve and decision curve(DCA)were used to evaluate the performance of the model.Results:①There were statistically sig-nificant differences in age,bilateral ovarian invasion,FIGO staging,menopause,neoadjuvant chemotherapy(NACT),chemotherapy interval(TTC),platelet count(PLT),platelet count/lymphocyte count ratio(PLR),fibrino-gen/lymphocyte count ratio(FLR),prognostic nutritional index(PNI),albumin(ALB),CA125 level,ascites volume,residual lesions,perioperative chemotherapy frequency,and CA125 half-life between the two groups(P＜0.05).②Multivariate Logistic regression analysis showed that bilateral ovarian invasion,FIGO stage Ⅳ,TTC＞16 days,ini-tial ascites volume＞1000ml,perioperative chemotherapy frequency＞9 times,surgery with R2 resection,CA125 half-life＞52 days were independent risk factors for recurrence of platinum-resistant AEOC patients(OR＞1,P＜0.05).③The AUC of the nomogram model constructed based on the above 7 indicators was 0.791(95％Cl 0.747-0.835),and the calibration curve and ideal curve fitted well.DCA showed that the net benefit interval of the model was 0.037-0.800.Conclusions:The nomogram prediction model based on independent risk factors for the recurrence of platinum-resistance of AEOC patients has good discrimination,calibration and clinical appli-cability,which can better predict the recurrence risk of platinum-resistance in AEOC patients after the initial treat-ment.
