Objective To propose a whole-life cycle management model for valvular heart disease (VHD), systematically elucidate its underlying logic and implementation pathways, and concurrently review and analyze its preliminary application outcomes. Methods Since 2020, West China Hospital of Sichuan University has established a management system encompassing "assessment-decision-intervention-follow-up", including: (1) a risk-stratified, tiered management pathway; (2) six core functions ("promotion, screening, prevention, diagnosis, treatment, and rehabilitation") coordinated by disease-specific managers; (3) an intelligent decision support information platform; and (4) a collaborative network of multidisciplinary teams and regional academic alliances. To evaluate the effectiveness of this management model, we retrospectively included three cohorts: (1) the population screened by echocardiography from 2020 to 2024, analyzing the detection rate of aortic valve disease and risk stratification; (2) patients enrolled in the whole-life cycle management from April 2021 to December 2024, assessing follow-up outcomes, hospital satisfaction, and changes in quality of life; (3) patients who underwent transcatheter aortic valve replacement (TAVR) from January 2022 to January 2024, evaluating the one-year all-cause mortality rate, perioperative complications, and improvements in New York Heart Association (NYHA) classification. Results Between 2020 and 2024, a total of 583 874 individuals underwent echocardiographic screening. A total of 48 089 patients with aortic valve disease were identified, including 3 401 (7.1%) high-risk patients, 18 657 (38.8%) moderate-risk patients, and 26 031 (54.1%) low-risk patients. Among them, 2 417 patients were enrolled in whole-life cycle management. Patient satisfaction scores showed a yearly increase, rising from 73.89 points before 2020 to 93.74 points in 2024. The 1-year mortality rate in the TAVR cohort decreased to 5.3%, significantly lower than the 8.2% observed under early standard management between 2014 and 2019 (P<0.01). Conclusion Through process optimization and resource integration, the VHD whole-life cycle management model has demonstrated significant effectiveness in standardizing diagnostic and follow-up procedures, enhancing patient satisfaction and quality of life, and reducing mortality. These outcomes highlight its practical value for broader implementation in China.

A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.

Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules， such as limonene， linalool， linalool acetate， geraniol， and citronellol. These chemicals have been extensively studied and shown to have a variety of functions， including reducing anxiety， relieving depression， promoting sleep， and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled， they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier， thereby exerting effects on the central nervous system. Currently， the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However， the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances， including plant extracts and natural small molecule compounds， in antibacterial and antiviral fields and the regulation of nervous system activity. As a result， a deeper understanding of aromatherapy was achieved. At the same time， the potential of these aromatic substances for drug development was thoroughly explored， providing important references and insights for possible future drug research and application.

Objective To investigate the feasibility of developing a grading diagnostic model for schistosomiasis-induced liver fibrosis based on B-mode ultrasonographic images and clinical laboratory indicators. Methods Ultrasound images and clinical laboratory testing data were captured from schistosomiasis patients admitted to the Second People’s Hospital of Duchang County, Jiangxi Province from 2018 to 2022. Patients with grade I schistosomiasis-induced liver fibrosis were enrolled in Group 1, and patients with grade II and III schistosomiasis-induced liver fibrosis were enrolled in Group 2. The machine learning binary classification tasks were created based on patients’radiomics and clinical laboratory data from 2018 to 2021 as the training set, and patients’radiomics and clinical laboratory data in 2022 as the validation set. The features of ultrasonographic images were labeled with the ITK-SNAP software, and the features of ultrasonographic images were extracted using the Python 3.7 package and PyRadiomics toolkit. The difference in the features of ultrasonographic images was compared between groups with t test or Mann-Whitney U test, and the key imaging features were selected with the least absolute shrinkage and selection operator (LASSO) regression algorithm. Four machine learning models were created using the Scikit-learn repository, including the support vector machine (SVM), random forest (RF), linear regression (LR) and extreme gradient boosting (XGBoost). The optimal machine learning model was screened with the receiver operating characteristic curve (ROC), and features with the greatest contributions to the differentiation features of ultrasound images in machine learning models with the SHapley Additive exPlanations (SHAP) method. Results The ultrasonographic imaging data and clinical laboratory testing data from 491 schistosomiasis patients from 2019 to 2022 were included in the study, and a total of 851 radiomics features and 54 clinical laboratory indicators were captured. Following statistical tests (t = −5.98 to 4.80, U = 6 550 to 20 994, all P values < 0.05) and screening of key features with LASSO regression, 44 features or indicators were included for the subsequent modeling. The areas under ROC curve (AUCs) were 0.763 and 0.611 for the training and validation sets of the SVM model based on clinical laboratory indicators, 0.951 and 0.892 for the training and validation sets of the SVM model based on radiomics, and 0.960 and 0.913 for the training and validation sets of the multimodal SVM model. The 10 greatest contributing features or indicators in machine learning models included 2 clinical laboratory indicators and 8 radiomics features. Conclusions The multimodal machine learning models created based on ultrasound-based radiomics and clinical laboratory indicators are feasible for intelligent identification of schistosomiasis-induced liver fibrosis, and are effective to improve the classification effect of one-class data models.

Transcatheter aortic valve implantation (TAVI) is an important alternative in treating high-risk patients with aortic valve regurgitation. Transcatheter tricuspid valve implantation (TTVI) is also an important treatment option for high-risk patients with tricuspid regurgitation. We reported a 72-year male patient who underwent TAVI due to severe aortic valve regurgitation using a J-Valve. During a two-year follow-up, the patient developed secondary tricuspid regurgitation to atrial fibrillation, and subsequently received TTVI using a LuX-Valve. Following the interventions, the patient's symptoms were significantly improved, and echocardiography indicated good hemodynamic performance of both transcatheter heart valves. This case highlights the feasibility and effectiveness of performing multiple valve implantations via transcatheter approaches in high-risk elderly patients.

Objective:To understand the prevalence and characteristics of Rhinovirus (HRV) infection in influenza-like Illness (ILIs) patients in Mianyang, Sichuan province, China.Methods:Throat swabs were collected from patients of ILIs in sentinel hospitals in Mianyang during 2021—2022. Real-time fluorescence quantitative PCR was used to detect 16 common pathogens. The VP4/VP2 coding region genes of HRV positive samples were amplified by nest PCR. The phylogeny, consistency and amino acid variation of different serotypes were analyzed and compared with reference sequences from GenBank database.Results:A total of 332 ILIs′ samples were collected with a virus detection rate of 58.73% (195/332) in Mianyang. Among them, 23 samples (23/332) were HRV-positive, and 18 VP4/VP2 sequences of HRV strains were successfully amplified. It was found that 13 HRV serotypes were detected in ILIs samples in Mianyang, which belonged to three genotypes, namely HRV-A (12 strains), HRV-B (5 strains) and HRV-C (1 strain).Conclusions:HRV was one of the pathogens of ILIs cases in Mianyang during 2021—2022, with HRV-A types as the dominant strains.

Based on high-resolution magnetic resonance tube wall imaging,reverse medical engineering modeling techniques are used to obtain individualized intracranial artery models of high prevalence in ischemic stroke.Three types of intracranial artery models,including Newtonian fluid model,non-Newtonian fluid model and non-Newtonian fluid with two-phase flow model,are established for transient numerical simulations using computational fluid dynamics method.The hemodynamic parameters such as blood flow field,wall shear stress distribution and erythrocyte volume distribution are analyzed to investigate the possible mechanisms involved in the formation and progression of intracranial atherosclerosis.It is found that blood flow velocity increased significantly at the end of the internal carotid artery and the middle cerebral artery.Low-speed vortex flow and disturbed flow appear in the local vessels.The difference in blood flow velocity between the center and the edge of the wall is large,with an obvious low-flow velocity area on the outer side.A clear central core area is formed in the stenotic wall under the action of high-speed blood flow,resulting in thinner edge layer and lower erythrocyte volume fraction.The combination of low erythrocyte distribution in the edge layer and low flow velocity on the outer side of the wall exacerbates endothelial cell necrosis,hypoxia,endothelial dysfunction,and leads to atherosclerosis.Compared with Newtonian and non-Newtonian fluid models,non-Newtonian fluid with two-phase flow model has greater variability for hemodynamic parameters and shows higher fidelity in simulating blood flow,which provides a reference for clinical diagnosis and treatment of cerebrovascular diseases.

Objective:To evaluate oncological and reproductive outcomes of women ≤40 years undergoing fertility-sparing surgery (FSS) for stage Ⅱ or Ⅲ borderline ovarian tumor (BOT).Methods:The patients with BOT and ≤40 years old with stage Ⅱ-Ⅲ BOT who underwent FSS enrolled from the First Affiliated Hospital of Zhengzhou University between January 2011 and March 2023 were analyzed retrospectively. The clinical data and follow-up results were obtained and analyzed. The univariate and multivariate Cox proportional hazard regression analysis were used to explore high-risk factors associated with prognosis. Additionally, pregnancy outcomes were also analyzed.Results:(1) A total of 79 patients with stage Ⅱ-Ⅲ BOT who have been treated with FSS were conducted, with an average age of (27.5±6.7) years old. The median tumor maximum diameter were 10.4 cm (range: 4.8-90.0 cm). The International Federation of Gynecology and Obstetrics (FIGO) stage was stage Ⅱ in 45 cases and stage Ⅲ in 34 cases. According to the pathological types, there were 48 cases of serous tumor, 21 cases of mucinous tumor, 1 case of endometrioid tumor, and 9 cases of mixed types. There were 41 cases of unilateral ovarian involvement, 38 cases of bilateral ovarian involvement. There were 5 cases of microinvasion, 17 cases of micropapillary subtype. Extra-ovarian invasive implants were found in 5 cases, and there were 31 cases of merged ascites. (2) Tumor outcomes: the median follow-up time from primary cytoreduction were 58 months (range: 8-146 months). At the end of the observation period, 24 cases (30%, 24/79) recurred, among them 5 cases had two recurrences and 2 cases had three recurrences. There were 2 cases (3%, 2/79) of death and 1 case (1%, 1/79) of survival with tumor. (3) Analysis of prognostic risk factors: the results of univariate analysis showed that mucinous tumor, tumor maximum diameter >13.15 cm, FIGO stage Ⅲ, merged ascites, micropapillary subtype, invasive implantation, and bilateral ovarian involvement were independent risk factors (all P<0.05) for disease-free survival (DFS). FIGO stage Ⅲ ( HR=4.555, 95% CI: 1.525-13.607; P=0.007) and micropapillary subtype ( HR=2.396, 95% CI: 1.003-5.725; P=0.049) were found to be related to DFS through the multivariable Cox proportional hazard regression analysis. (4) Pregnancy outcomes: among the patients with fertility intentions 36 cases (46%,36/79), 29 cases (81%, 29/36) had successful pregnancies, and 27 cases (75%, 27/36) had successful births. Conclusions:Patients with stage Ⅱ-Ⅲ BOT underwent FSS have favorable survival and pregnancy rates. Micropapillary subtypes and FIGO staging (stage Ⅲ) are the significant risk factors of DFS.

Objective:To compare the efficacy of acetabular magic hook plates versus quadrilateral area combined plates in treating complicated acetabular fractures.Methods:A retrospective analysis was conducted on 44 cases of complicated acetabular fractures treated at the Department of Orthopaedics, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from June 2017 to August 2022. Among these cases, 21 were treated with magic hook plate internal fixation (hook plate group) and 23 with quadrilateral area combined plate internal fixation (combined plate group). In the hook plate group, there were 15 males and 6 females, with an average age of 43.1±11.8 years. According to the Letournel-Judet classification, there were 13 double-column fractures, 5 anterior column with posterior semi-transverse fractures, and 3 T-type fractures. Additionally, 8 cases were classified as B2.2 type, 5 as C1 type, 4 as C2 type, and 4 as C3 type; 15 cases were APQ1 type and 6 were APQ2 type. In the combined plate group, there were 16 males and 7 females, with an average age of 41.7±12.8 years. This group included 15 double-column fractures, 6 anterior column with posterior semi-transverse fractures, and 2 T-type fractures. Additionally, there were 8 cases of B2.2 type, 6 cases of C1 type, 4 cases of C2 type, and 5 cases of C3 type; 15 cases were APQ1 type and 8 were APQ2 type. Comparative analyses included operative time, intraoperative blood loss, fracture healing time, Matta standard assessment, modified Merle d'Aubign-Postel scores, and postoperative complications.Results:All 44 patients were followed up for 10 to 24 months, with an average follow-up of 14 months. The acetabular fractures healed in all cases. The healing time was 3.6±0.9 months for the hook plate group and 3.7±0.9 months for the combined plate group, with no significant difference between the groups ( t=0.549, P=0.586). The hook plate group had an operative time of 138.3±30.7 minutes and intraoperative blood loss of 735.7±159.8 ml, compared to 163.9±48.7 minutes and 843.5±181.1 ml, respectively, in the combined plate group, both of which were statistically significant ( P<0.05). The reduction quality was excellent in 13 cases, good in 5 cases, and poor in 3 cases in the hook plate group, with an excellent and good rate of 86% (18/21). In the combined plate group, the reduction quality was excellent in 13 cases, good in 6 cases, and poor in 4 cases, with an excellent and good rate of 83% (19/23), showing no significant difference between the groups (χ 2=0.143, P=0.931). The modified Merle d'Aubign Postel scores of the hook plate group were 13.8±2.2 points, 15.3±2.5 points and 16.7±1.8 points at 3 months, 6 months and the last follow-up, respectively, and the combined plate group were 13.1±1.9 points, 14.6±2.1 points and 16.4±2.0 points, respectively ( P>0.05). However, both groups showed statistically significant improvements in hip function over time ( F=9.658, P<0.001; F=16.195, P<0.001). Wound fat liquefaction and lateral femoral cutaneous nerve injury occurred in one case each in both groups. In the combined plate group, there were 3 cases of incision fat liquefaction, 2 cases of lateral femoral cutaneous nerve injury, and 1 case of traumatic hip arthritis. No other complications such as incision infection, iliac vascular injury, or loss of internal fixation were observed in either group. Conclusion:Both magic hook plate fixation and quadrilateral area combined plate fixation are safe and effective for treating complex acetabular fractures. However, magic hook plate fixation offers advantages in reducing operative time and intraoperative blood loss, thereby simplifying and enhancing the safety of the procedure.
