BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

The anterior cruciate ligament (ACL), anterolateral complex (ALC) and lateral meniscus (LM) maintain the anterolateral rotatory stability of the knee and control the internal rotation of the tibia. Anterolateral rotatory instability (ALRI) of the knee is not uncommon in clinic, and its main injury mechanism is non-contact injury. A pivot shift test or a tibial internal rotation test can indicate ALRI while X-ray, CT, MRI and ultrasound can assist in its diagnosis and differential diagnosis. For acute ALRI, good technique of ACL reconstruction is the basis to avoid postoperative residual ALRI, and anterolateral ligament reconstruction and extra-articular tenodesis are optional as appropriate. For chronic cases, however, both anterolateral ligament reconstruction and extra-articular tenodesis are effective. This article reviews the progress in research on the diagnosis and treatment of ALRI of the knee, hoping to provide references for its clinical diagnosis and treatment.

Chronic refractory wound (CRW) is one of the most challengeable issues in clinic due to complex pathogenesis, long course of disease and poor prognosis. Experts need to conduct systematic summary for the diagnosis and treatment of CRW due to complex pathogenesis and poor prognosis, and standard guidelines for the diagnosis and treatment of CRW should be created. The Guideline forthe diagnosis and treatment of chronic refractory wounds in orthopedic trauma patients ( version 2023) was created by the expert group organized by the Chinese Association of Orthopedic Surgeons, Chinese Orthopedic Association, Chinese Society of Traumatology, and Trauma Orthopedics and Multiple Traumatology Group of Emergency Resuscitation Committee of Chinese Medical Doctor Association after the clinical problems were chosen based on demand-driven principles and principles of evidence-based medicine. The guideline systematically elaborated CRW from aspects of the epidemiology, diagnosis, treatment, postoperative management, complication prevention and comorbidity management, and rehabilitation and health education, and 9 recommendations were finally proposed to provide a reliable clinical reference for the diagnosis and treatment of CRW.

High-throughput sequencing has the characteristics of complex experimental procedures, multiple quality control nodes, and a high proportion of bioinformatics technology. It is difficult to uniformly management and reuse the related detection samples and data. In May 2023, a tertiary hospital launched the construction of a localized high-throughput sequencing management system. Based on the design principles of security, friendliness, compatibility, and scalability, the management system had established three core modules: standardized data collection integration, clinical high-throughput sequencing full process management, and scientific research services, as well as a large clinical high-throughput sequencing database of hospital. By connecting with big data storage devices, local and third-party high-throughput sequencing detection platforms, sample libraries, and user terminals, this system broke down the data barriers of high-throughput sequencing related systems and devices, and met the different application scenarios of physician users, technician users, management users, and scientific research users in the hospital. As of October 2023, the system had been integrated with two high-throughput sequencing manufacturer devices in a public network environment and hospital information systems in an internal network environment, improving data retrieval efficiency and achieving closed-loop management of high-throughput sequencing detection projects preliminary, which can provided references for promoting the standardized management of high-throughput sequencing projects in hospitals in China.

Objective:To identify the risk factors for premature proximal femur physeal closure (PPC) in children treated surgically for femoral neck fractures.Methods:Data of 106 children with an open triradiate cartilage who were treated surgically for a femoral neck fracture were retrospectively analyzed. Age, gender, laterality, mechanism of injury, the type of fracture, initial displacement, time to reduction, fixation method, whether the implant crossed the physeal plate, reduction method, reduction quality and development of femoral head avascular necrosis (AVN) were collected. PPC of the proximal femur was assessed through postoperative 6-12 months radiographs.Results:A total of 106 patients with an open triradiate cartilage were followed up, with an average duration of 20.4±13.3 months (range, 6-86 months). The overall rate of PPC following paediatric femoral neck fractures treated surgically was 36.8% (39/106). Among the 39 patients with PPC, 25 were males and 14 were females; the average age at the time of injury was 9.7±3.6 years (range, 3-15 years); 23 patients were involved in left hips and 16 were in right; the mechanisms of injury included motor vehicle accident in 5 fractures, falling injury in 21, sports-related injury in 12 and other causes in 1 fracture; two hips were Delbet type I, and 26 hips and 11 hips were Delbet type II and III, separately; type II and III of initial displacement were involved in 26 and 13 patients, separately; the mean duration from injury to surgery was 3.3±2.8 d (range, 1-14 d); 2 hips were treated with Kirschner wires, 35 hips with screw fixation, and the remaining 2 hips underwent screw and plate fixation; 2 hips had the hardware crossing the proximal femoral growth plate, and the remaining 37 hips didn’t; 15 hips were treated by closed reduction and internal fixation, and the other 24 hips underwent open reduction and internal fixation; anatomical reduction was achieved in 14 patients, acceptable reduction in 24 hips and unacceptable reduction in 1 hip; 24 hips developed AVN at the latest follow-up and the remaining 15 hips didn’t. Statistical analysis indicated that age ( t=3.875, P< 0.001), the severity of initial displacement ( Z=-2.118, P=0.034) and the rate of AVN ( χ2=42.280, P< 0.001) in patients with PPC were significantly higher than those in patients without; Logistic regression analysis confirmed age ( OR=1.288, P=0.011) and AVN ( OR=40.336, P< 0.001) as risk factors for PPC. ROC curve analysis indicated 10 years was the cut off age to significantly increase the rate of PPC. The rate of PPC in patients aged over 10 years (63.6%, 21/33) was significantly higher than that (24.7%, 18/73) in those aged less than 10 years ( χ2=14.848, P< 0.001). Conclusion:Age over 10 years and AVN are risk factors for PPC in children with femoral neck fractures treated surgically.

Objective:To investigate high mobility group protein 1(HMGB1), tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)levels and their clinical significance in elderly patients with viral pneumonia.Methods:One hundred and sixty elderly patients with viral pneumonia admitted to the Sixth Hospital Affiliated to Anhui Medical University were enrolled as research subjects.In addition, 40 elderly people who underwent regular physical examination were considered as the control group.Patients with viral pneumonia were divided into the low-risk group, middle-risk group and high-risk group according to CURB-65 scores and pneumonia severity index(PSI)scores.HMGB1, TNF-α and IL-6 levels were compared between different groups.The correlations of CURB-65 scores and PSI scores with HMGB1, TNF-α, IL-6 levels were analyzed.Multivariate Logistic regression analysis was used to examine influencing factors for the severity of viral pneumonia in elderly patients.Results:HMGB1, TNF-α and IL-6 levels were higher in research subjects than in the control group.As the severity of viral pneumonia increased, so did HMGB1, TNF-α and IL-6 levels(all P<0.05). HMGB1, TNF-α and IL-6 levels in the severe viral pneumonia group were significantly higher than those in the non-severe viral pneumonia group( P<0.05). HMGB1, TNF-α and IL-6 levels were positively correlated with CURB-65 scores and PSI scores(CURB-65 score: r=0.463, 0.392 and 0.497, P=0.015, 0.003 and 0.025; PSI score: r=0.596, 0.515 and 0.381, P=0.007, 0.011 and 0.009). HMGB1, TNF-α and IL-6 levels were influencing factors for the severity of viral pneumonia in elderly patients( OR=1.344, 1.422 and 1.351, P=0.006, 0.015 and 0.009). Conclusions:HMGB1, TNF-α and IL-6 levels are closely correlated with the severity of viral pneumonia and are helpful for early assessment of viral pneumonia.

Objective:To explore the effect of mobile health (mHealth) management system on dietary behavior of patients with coronary heart disease (CHD) .Methods:Using the convenient sampling method, CHD patients who were hospitalized in Department of Cardiology of Beijing Anzhen Hospital and Beijing Chaoyang Hospital of Capital Medical University were selected as the research objects from June 2019 to January 2020. The research objects were randomly divided into the intervention group and the control group using SAS software. Finally, 68 cases in the intervention group and 66 cases in the control group completed the study. The intervention group received mhealth management, while the control group received routine management, and they were followed up to 1 month after discharge. The proportion of patients with the low-salt and low-oil diet, the intake of salt, oil, staple food, vegetables, fruits, fish, shrimp, poultry and eggs, BMI and blood pressure were compared between the two groups.Results:At 1 month follow-up, the intervention group was better than the control group in terms of low salt and low oil diet, salt intake, oil intake and vegetable intake compliance, and the differences were statistically significant ( P<0.05) . At 1 month follow-up, there were no statistically significant differences in BMI and blood pressure between two groups ( P>0.05) . Conclusions:The mobile health system can effectively increase the proportion of patients with a low-salt and low-oil diet, and improve the intake compliance of salt, edible oil and vegetables in patients with CHD. In future studies, the intervention time should be extended to further explore the long-term intervention effect of mobile health and give full play to the role of mobile health in continuous behavior management of patients with CHD after discharge.

Objective:To investigate the effects of Sacubitril/Valsartan on the recurrence of atrial fibrillation(AF), cardiac structure and function after catheter ablation(CA)of persistent AF.Methods:A total of 180 patients with persistent AF were randomly divided into the treatment group(n=90)and the control group(n=90)before undergoing CA.The control group was given routine perioperative medication according to the guidelines for AF management, and the treatment group was additionally given Sacubitril/Valsartan.Blood pressure, N-terminal pro-B-type natriuretic peptide(NT-proBNP), P-wave dispersion, left atrial dimension, left atrial volume index, mitral regurgitation area, left ventricular end-systolic volume index, end-diastolic volume index and left ventricular ejection fraction(LVEF)were measured at 3, 6 and 12 months after the procedure.Results:Blood pressure was lower in the treatment group than in the control group( P<0.05), but no hypotension or related symptoms occurred.The sinus rhythm maintenance rate was higher in the treatment group than in the control group at 3, 6 and 12 months during the follow-up(80.0%, 72.2%, 78.9% vs.70.0%, 75.6%, 68.9%, χ2=4.866, 6.667 and 4.091, P=0.027, 0.010 and 0.043, respectively). At 6 and 12 months during the follow-up, NT-proBNP, P-wave dispersion, left atrial diameter, left atrial volume index, mitral regurgitation area, left ventricular end-systolic volume index and end-diastolic volume index were lower(all P<0.05)and LVEF was higher( P<0.05)in the treatment group than in the control group. Conclusions:In patients with persistent AF after CA, Sacubitril/Valsartan has favorable effects in maintaining sinus rhythm, reversing cardiac remodeling and improving cardiac function.

Objective:To investigate the diagnostic performance of repeat biopsy 68Ga-PSMA PET/CT to distinguish between benign and malignant prostate disease. Methods:The clinical data and medical imaging of thirty-nine patients underwent repeat prostate biopsy were analyzed respectively in this study. The median age of patients was 65 years (range 46-81 years), the median PSA level was 11.0ng/ml (range 5.4-49.8 ng/ml), f/tPSA was 0.15(0.01-16.50)ng/ml, prostate volume was 43.80(7.79-108.63)ml, and PSA density was 0.24(0.09-2.31)ng/ml 2. All patients underwent pre-biopsy 68Ga-PSMA PET/CT and the standard transrectal ultrasound-guided systematic prostate biopsy. Based on the biopsy results, 68Ga-PSMA PET/CT images of all patients were visually and semi-quantitatively analyzed. By visual analysis, 68Ga-PSMA uptake in prostate was defined as focal, multimodal and inhomogeneous, and then the detection rate of prostate cancer in each subgroup was analyzed. The value of the ROC curve in the diagnosis of prostate cancer was analyzed based on the SUV max of prostate cancer(SUV max), tumor-to-normal-prostate background(SUV T/BGp)as semi-quantitative parameters of 68Ga-PSMA PET/CT. Results:Prostate cancer was detected in 18 patients (46.2%) and 12 patients (30.8%) had clinically significant disease. There were 11, 5 and 2 patients with prostate cancer respectively in men with a focal (12 patients), multifocal(7 patients) and inhomogeneous (20 patients) 68Ga-PSMA uptake. The ROC analysis revealed a SUV max 5.3 and SUV T/BGp1.8 as an optimal cut-off level to distinguish between non-prostate cancer and prostate cancer in 68Ga-PSMA PET/CT, the sensitivity and specificity were 100.0% and 85.7% for SUV max (AUC=0.979), 83.3% and 90.5% for SUV T/BGp (AUC=0.915). Conclusions:Pre-biopsy 68Ga-PSMA PET/CT could help to distinguish between benign and malignant prostate disease before repeat prostate biopsy and detect the foci of prostate cancer.

PURPOSE: Details of patients hospitalized for asthma exacerbation in mainland China are lacking. To improve disease control and reduce economic burden, a large sample survey among this patient population is indispensable. This study aimed to investigate the clinical characteristics and outcomes of such patients.METHODS: A retrospective study was conducted on patients hospitalized for asthma exacerbation in 29 hospitals of 29 regions in mainland China during the period 2013 to 2014. Demographic features, pre-admission conditions, exacerbation details, and outcomes were summarized. Risk factors for exacerbation severity were analyzed.RESULTS: There were 3,240 asthmatic patients included in this study (57.7% females, 42.3% males). Only 28.0% used daily controller medications; 1,287 (39.7%) patients were not currently on inhaled corticosteroids. Acute upper airway infection was the most common trigger of exacerbation (42.3%). Patients with severe to life-threatening exacerbation tended to have a longer disease course, a smoking history, and had comorbidities such as hypertension, chronic obstructive pulmonary disease (COPD), and food allergy. The multivariate analysis showed that smoking history, comorbidities of hypertension, COPD, and food allergy were independent risk factors for more severe exacerbation. The number of patients hospitalized for asthma exacerbation varied with seasons, peaking in March and September. Eight patients died during the study period (mortality 0.25%).CONCLUSIONS: Despite enhanced education on asthma self-management in China during recent years, few patients were using daily controller medications before the onset of their exacerbation, indicating that more educational efforts and considerations are needed. The findings of this study may improve our understanding of hospital admission for asthma exacerbation in mainland China and provide evidence for decision-making.
