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.

Objective: To assess the feasibility of endovascular thrombectomy (EVT) for the treatment of acute ischemic stroke (AIS) in children. Methods: Clinical data and follow-up information of 4 AIS children who received EVT in the Department of Intervention & Hemangioma at the Children's Hospital of the Capital Institute of Pediatrics from December 2020 to June 2021 were collected retrospectively. The vascular recanalization after EVT was assessed by the modified thrombolysis in cerebral infarction (mTICI) score. Efficacy outcomes were assessed with initial and postprocedural Pediatric National Institutes of Health Stroke Scale (PedNIHSS) score, and the modified Rankin scale (mRS) score at 3 and 6 months after treatment. Safety assessments included perioperative complications and intracranial hemorrhage post-treatment. Results: A total of 5 EVT treatment were performed on 4 children with AIS, of whom 3 were male. The age of onset was 4.6, 13.8, 7.8, 8.0, 8.9 years, respectively. The time from symptom onset to initiation of EVT was 19.0, 25.0, 22.0, 4.0, 16.5 hours, respectively and all patients achieved successful recanalization of the vessel after EVT (mTICI≥2b). The PedNIHSS score was 39, 14, 25, 39, 24 before treatment and decreased to 8, 1, 12, 39, 5 at discharge. All the procedures were performed with no perioperative complications. Only 1 patient with congenital heart disease had a recurrent AIS with malignant brain oedema and brain hernia. Although the occluded vessels were successfully recanalized,the symptoms were not improved and this patient died after treatment abandonment. The other 3 patients achieved good recovery at 6 months postoperatively. The mRS score of 3 patients was 3, 1, 2 at 3 months after EVT and decreased to 2, 1, 1 at 6 months. Conclusion: EVT treatment may be feasible and safe for pediatric AIS due to large vessel occlusion even when the treatment was initiated 6 hours post stroke, but children with heart disease may have a dismal prognosis.

To maintain the precision and stability of the efficacy of classical formulas, this study compared the origins and specifications of Bupleuri Radix and revealed the precise application regularity of Bupleurum chinense(Beichaihu) and Bupleurum scorzonerifolium(Nanchaihu) in classical formulas. The efficacy and indications of formulas with Bupleuri Radix as the sovereign drug in the Treatise on Cold Damage and Miscellaneous Diseases(Shang Han Za Bing Lun) were investigated. The difference in the efficacy of Bupleuri Radix as well as the differences in the chemical composition, and liver-protecting and lipid-lowering effects of the decoctions of Beichaihu and Nanchaihu were analyzed with LC-MS technology based on the CCl_4-induced liver injury model in mice and sodium oleate-induced HepG2 hyperlipidemia cell model. The results showed that seven classical formulas with Bupleuri Radix as the sovereign drug in the Treatise on Cold Damage and Miscellaneous Diseases were mainly used in the treatment of digestive, metabolic, immune, circulatory, and other diseases. Bupleuri Radix mainly played the functions of protecting the liver, benefiting the gallbladder, and lowering the lipid, and had different focuses in different formulas. There were 14 differential components in the decoctions of Beichaihu and Nanchaihu, and the chemical structures of 11 components were identified, including 10 saponins and one flavonoid. The results of the liver-protecting efficacy experiment showed that compared with the Nanchaihu decoction, Beichaihu decoction could reduce the serum aspartate aminotransferase(AST) activity in liver injury model mice(P<0.01). The results of the lipid-lowering efficacy experiment proved that Beichaihu and Nanchaihu decoctions both showed highly significant differences in lowering the total cholesterol(TC) and triglyceride(TG) content in HepG2 cells(P<0.01), and Nanchaihu decoction was superior to Beichaihu decoction in lowering the lipid. The results of this study preliminarily proved that there were differences in chemical composition, and liver-protecting and lipid-lowering effects of Beichaihu and Nanchaihu decoctions, indicating that it was necessary to determine the precise origin of Bupleuri Radix in the clinical formulation of traditional Chinese medicine. The study provides a scientific basis for both precise clinical medication and purpose-based accurate quality evaluation of traditional Chinese medicine in clinical application.

OBJECTIVE: To evaluate the clinical outcomes of reverse total shoulder arthroplasty as a revision procedure for the failed fixation of proximal humeral fractures in the elderly patients. METHODS: A retrospective analysis was performed on 8 patients with failed internal fixation of proximal humeral fractures from May 2014 to March 2020, including 3 males and 5 females, aged from 65 to 75 years old. All 8 patients underwent reverse total shoulder arthroplasty, and the mean time between initial fixation and reverse total shoulder arthroplasty ranged from 8 to 16 months. Range of motion(ROM), University of California at Los Angeles(UCLA) shoulder score, visual analogue scale (VAS), self-rating anxiety scale(SAS), and Constant-Murley score of shoulder function were assessed pre-operatively and at the last follow-up. Complications relating to the surgery were recorded. RESULTS: All 8 patients successfully followed up. The mean follow-up after reverse total shoulder arhroplasty ranged from 16 to 28 months. The range of motion (forward flexion, external rotation, abduction and internal rotation) of the affected shoulder was significantly improved after surgery, and the post-operative VAS, SAS and UCLA scores were also significantly improved. For the Constant-Murley score of shoulder joint function, the total scores and the subscores of pain, daily activities, range of motion and strength test at the last follow-up were all significantly improved. Scapular glenoid notch was observed in patient, which was evaluated as grade 1 on imaging. All the other patients did not develop specific or non-specific complications. CONCLUSION Reverse total shoulder arhroplasty is an appropriate treatment as a revision surgery for failed fixation of proximal humeral fractures. It has shown satisfactory clinical outcomes, accelerating the rehabilitation of shoulder function and improving the quality of life.

In recent years, the types and quantities of fentanyl analogs have increased rapidly. It has become a hotspot in the illicit drug control field of how to quickly identify novel fentanyl analogs and to shorten the blank regulatory period. At present, the identification methods of fentanyl analogs that have been developed mostly rely on reference materials to target fentanyl analogs or their metabolites with known chemical structures, but these methods face challenges when analyzing new compounds with unknown structures. In recent years, emerging machine learning technology can quickly and automatically extract valuable features from massive data, which provides inspiration for the non-targeted screening of fentanyl analogs. For example, the wide application of instruments like Raman spectroscopy, nuclear magnetic resonance spectroscopy, high resolution mass spectrometry, and other instruments can maximize the mining of the characteristic data related to fentanyl analogs in samples. Combining this data with an appropriate machine learning model, researchers may create a variety of high-performance non-targeted fentanyl identification methods. This paper reviews the recent research on the application of machine learning assisted non-targeted screening strategy for the identification of fentanyl analogs, and looks forward to the future development trend in this field.
