Objective:To explore the implementation effects of an proactive health management model for elderly patients with multimorbidity in comprehensive hospitals based on the concept of people-centered integrated care (PCIC).Methods:This study was a randomized controlled trial. Elderly patients who were hospitalized in the Department of General Practice at Shanghai East Hospital Tongji University and also suffered from hypertension, type 2 diabetes and dyslipidemia from November 2022 to January 2024 were included, and were divided into the control group (traditional health management, n=25) and the intervention group (proactive health management, n=25) using the random number table method. A research team comprising experts in general medicine, pharmacy, nutrition, rehabilitation medicine, psychology, and other relevant specialties was formed. Based on literature analysis, clinical experience, and hospital resources, the team collaborated to develop a comprehensive, hospital-based proactive health management model for elderly patients with comorbidities based on the PCIC concept. Patients in the control group were managed using the traditional health management model. Patients in the intervention group were managed using the proactive health management model. Baseline clinical data was collected and the patients were followed up for 6 months. At the 6-month follow-up, data on blood pressure, fasting blood glucose, and blood lipids were collected, as well as information on polypharmacy, activities of daily living (ADL) ability, 10-year atherosclerotic cardiovascular disease (ASCVD) risk, and unplanned rehospitalization were recorded. Results:A total of 50 patients were enrolled, with 25 patients in each group. The control group had an average age of (70.40±6.54) years, with 15 males(60.0%). The intervention group had an average age of (71.20±5.14) years, with 16 males(64.0%). At the 6-month follow-up, the standardization rates of blood pressure, fasting blood glucose, glycated hemoglobin, low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and triglycerides (TG) in both groups were higher than those in the baseline (all P<0.05).In addition, patients in the intervention group had the compliance rates for higher blood pressure, fasting blood glucose, 2-hour postprandial blood glucose, HbA1c, LDL-C, non-HDL-C, and TG than the control group (all P<0.05).At the 6-month follow-up, the 10-year ASCVD high-risk patient percentage decreased in the intervention group compared with baseline ( P=0.023) and was lower than that of the control group ( P=0.045), and the unanticipated readmission rate of patients in the intervention group was also lower than that of the control group ( P=0.042). Conclusions:A proactive health management model for elderly patients with geriatric multimorbidity in a comprehensive hospital, based on the concept of PCIC, was applied to an elderly population with concurrent hypertension, type 2 diabetes and dyslipidemia. The results of the management were favorable.

【Objective】 To measure and analyze foot development indicators of children under 3 years old, in order to provide basis for the correct clinical assessment of children foot development. 【Methods】 A total of 5 894 children under 3 years old who took physical examination in the Child Health Care Department of Xi′an People′s Hospital from August 2022 to March 2023 were randomly selected. Foot length, foot width, the ratio of foot width to length and arch index were measured by image processing system, and were compared among different age groups and sex groups. 【Results】 1) Foot length, foot width and arch index of children under 3 years old increased significantly with age, while the ratio of foot width to length decreased significantly with age(F=1 345.23, 396.21,184.65, 287.03, P<0.05). 2) There was no statistical significance in foot length, foot width and arch index between left and right foot of children under 3 years old(P>0.05). 3) Foot length and foot width of boys were greater than those of girls in all age groups, and the difference was statistically significant(tfoot length:3.45 - 10.19, tfoot width: 3.77 - 9.21, P<0.05). There was no significant difference in arch index between boys and girls in all age groups(P>0.05). 【Conclusion】 Foot shape of children under 3 years old changes with age, there are differences in foot length and width between boys and girls.

Objective:To investigate the clinical and radiologic characteristics of children with congenital pseudarthrosis of the tibia (CPT) in a single center.Methods:This is a retrospective case series study. According to inclusion and exclusion criteria, clinical data of 497 children(507 limbs) with CPT who were treated at Department of Orthopedics, the Children′s Hospital Affiliated to Xiangya School of Medicine, Central South University from January 2011 to December 2020 were collected. Baseline data included gender, age at initial visit, age at onset of symptoms, accompanying symptoms, domicile, whether first treated at our hospital, and treatment-related information such as surgical or conservative treatment, surgical complications, etc., were extracted and analyzed using the health information system. Imaging data of the children, including Crawford classification, bilateral leg lengths, presence of fibular pseudarthrosis, and location of pseudarthrosis along the tibia segment, were analyzed using the Picture Archiving and Communication System. Data were compared using independent sample t test or χ2 tests. Results:Among 497 children with CPT, there were 305 males (61.4%) and 192 females (38.6%). The age at initial visit was (3.6±3.2) years (range: 0.1 to 16.2 years). Neurofibromatosis type 1 (NF1) symptoms were positive in 340 children (68.4%), and negative in 157 children (31.6%). Among NF1-positive children, those with symptoms onset before 1 year of age were significantly more than NF1-negative children (74.1%(252/340) vs. 66.2%(104/157); χ2=9.24, P=0.001), and the proportion of fractures (92.9%,316/340) was significantly higher than that in the NF1-negative group (84.7%,133/157) ( χ2=8.33, P=0.004). According to imaging data, Crawford type Ⅳ was the most common type, with 321 limbs (63.3%), followed by type Ⅱ in 100 limbs (19.7%), type Ⅲ in 54 limbs (10.7%) and type Ⅰ in 32 limbs (6.3%). Pseudarthrosis occurred in the proximal third of the tibia in 14 limbs (2.8%), in the middle third in 185 limbs (36.5%), and in the distal third in 308 limbs (60.8%). Seventy-four children (14.9 %) had associated fibular pseudarthrosis. The lateral proximal tibial angle was 86.91°±5.21°(range: 72.17° to 102.08°), and the lateral distal tibial angle was 87.27°±10.73°(range: 51.07° to 128.17°). A total of 421 children (84.7%) underwent surgical treatment with (3.1±2.4) surgeries performed per child (range:0 to 12 surgeries); 76 children (15.3%) received conservative treatment. Postoperative complications mainly included ankle valgus (77 cases), leg length discrepancy (71 cases),refracture (48 cases), osteomyelitis (11 cases), and hardware failure (10 cases). NF1-positive children underwent more surgeries than NF1-negative children ((5.1±2.2)times vs.(2.1±1.8)times; t=14.93, P<0.01). Conclusions:Crawford type Ⅳ is the most common type of CPT in children in this study. CPT predominantly occurs in the middle or distal third of the tibia. The majority of children with CPT experienced symptoms and were seen at outpatient clinics before the age of 3 years. The main surgical complications currently associated with CPT treatment are ankle valgus and leg length discrepancy. Compared with CPT without NF1, children with NF1-positive CPT tend to have earlier symptom onset and may require more frequent treatments.

Objective To investigate the mechanism of copper ionophore elesclomol induced cuproptosis in endometrial cancer cells.Methods HEC-1-A cells were treated with different concentrations of copper ion carrier elesclomol and copper chloride.Cell proliferation was detected using a cell counting kit(CCK-8)assay.Enzyme-linked immunosorbent assay(ELISA)detected mitochondrial respiratory chain complexesⅠ,Ⅱ,Ⅲ,and IV.Quantitative real-time polymerase chain reaction(qRT-PCR)was used to detect mRNA expression.Western blotting and immunohistochemistry were used to detect protein expression.Results Adding elesclomol or copper chloride alone to HEC-1-A cells did not affect cell survival.However,the simultaneous addition of 50 nmol·L-1 elesclomol and 1 μmol·L-1 copper ions caused a significant decrease in cell survival(P＜0.01).Elesclomol-induced HEC-1-A cell death does not involve the apoptosis mechanism.After treatment with 50 nmol·L-1 elesclomol and 1 μmol·L-1 copper ions in HEC-1-A cells,the levels of mitochondrial respiratory chain complexes Ⅰ,Ⅱ,and Ⅲsignificantly increased.After knocking down ferredoxin 1(FDX1),the cuproptosis in HEC-1-A cells was significantly inhibited(P＜0.01).In addition,FDX1 was under-expressed in endometrial cancer tissues.Conclusion Elesclomol may promote cuproptosis in endometrial cancer cells through the FDX1/mitochondrial respiratory pathway.

Transcatheter tricuspid valve intervention is the new frontier of interventional cardiology. The LuX-Valve is a radial force-independent orthotopic tricuspid valve replacement device developed in China. The LuX-Valve Plus transcatheter tricuspid valve replacement (TTVR) system is changed from the trans-atrial to the transjugular approach, which further reduces trauma and pulmonary complications compared with the first generation LuX-Valve. The first-in-human study has been completed at Zhongshan Hospital, Fudan University and an exploratory multicentre clinical study is underway. Echocardiography plays an important role in pre-TTVR screening, intraoperative guidance and postoperative evaluation and follow-up, especially two-dimensional transoesophageal echocardiography (2D-TEE) and three-dimensional transoesophageal echocardiography (3D-TEE). However, there is a lack of appropriate intraoperative guidance and assessment protocols. In this study, we briefly described the protocols and imaging considerations for intraoperative 2D-TEE and 3D-TEE to ensure the successful implantation of TTVR.

Objective     To evaluate the safety and efficacy of transcatheter aortic valve replacement (TAVR) using the SAPIEN 3 system. Methods    This was a prospective, multicenter, single arm study in 4 centers in China. The clinical data of 50 patients with high-risk symptomatic severe aortic stenosis who underwent TAVR using the SAPIEN 3 system from June 2017 to June 2019 were analyzed, including 27 males and 23 females aged 76.8±6.1 years. Results    The Society of Thoracic Surgeon score was 6.0%±2.8%. Totally, 20.0% of patients had severe bicuspid aortic stenosis. The operation time was 41.8±16.5 min and the hospital stay time was 8.5±5.0 d. At the postoperative 30-day follow-up, no all-cause mortality occurred and the device success rate was 89.5%. Major vascular complications occurred in one (2.0%) patient,  stroke in one (2.0%) patient, new pacemaker implantation in one (2.0%) patient, as well as coronary artery obstruction in one (2.0%) patient. There was no moderate or moderate/severe paravalvular leak. The aortic pressure gradient was decreased from 49.2±16.2 mm Hg before the operation to 12.4±4.6 mm Hg at the postoperative 30-day follow-up, and the valvular area was increased from 0.6±0.3 cm2 to 1.3±0.3 cm2 (P<0.01). Moreover, the New York Heart Association classification in 83.7% of the patients was improved during the follow-up. Conclusion    This pre-marketing multicenter study has demonstrated the safety and effectiveness of transfemoral TAVR with the SAPIEN 3 transcatheter valve system in Chinese aortic stenosis patients at high risk for surgery.
