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.

Surgery is the main clinical treatment for papillary thyroid carcinoma(PTC),and with the advancement of medical technology,PTC surgical treatment has made significant progress.However,there is still controversy in the academic community re-garding the scope of PTC surgical resection and lymph node dissection.Moreover,as PTC shows a trend towards youthfulness,patients′demands for surgical methods,surgical timing,surgical outcomes,and postoperative aesthetics are gradually increasing.Therefore,the choice of PTC surgical method needs to consider more aspects besides lesion resection and disease relief.This article reviews the pro-gress and limitations of surgical treatment for PTC.

A major challenge facing photodynamic therapy (PDT) is that the activity of the immune-induced infiltrating CD8⁺ T cells is subject to the regulatory T lymphocytes (Tregs), leaving the tumor at risk of recurrence and metastasis after the initial ablation. To augment the antitumor response and reprogram the immunosuppressive tumor microenvironment (TME), a supramolecular photodynamic nanoparticle (DACss) is constructed by the host-guest interaction between demethylcantharidin-conjugated β-cyclodextrin (DMC-CD) and amantadine-terminated disulfide-conjugated FFVLGGGC peptide with chlorin e6 decoration (Ad-ss-pep-Ce6) to achieve intelligent delivery of photosensitizer and immunomodulator for breast cancer treatment. The acid-labile β-carboxamide bond of DMC-CD is hydrolyzed in response to the acidic TME, resulting in the localized release of DMC and subsequent inhibition of Tregs. The guest molecule Ad-ss-pep-Ce6 can be cleaved by a high level of intracellular GSH, reducing photosensitizer toxicity and increasing photosensitizer retention in the tumor. With a significant increase in the CTL/Treg ratio, the combination of Ce6-based PDT and DMC-mediated immunomodulation adequately achieved spatiotemporal regulation and remodeling of the TME, as well as improved primary tumor and in situ lung metastasis suppression with the aid of PD-1 antibody.

It is believed that the pathogenesis of oculomotor nerve palsy is insufficient marrow sea （髓海）， withered yang qi， poor contraction of eyelids and periocular meridians， and inability to open and close the eyes. The eye system is connected to the marrow sea， as well as the the foot taiyang （太阳） channel， foot yangming （阳明） channel， foot jueyin （厥阴） channel， yinqiao mai （阴跷脉） and yangqiao mai （阳跷脉）， and is nourished by the liver， spleen and kidney. Treatment should take into account both the branch and the root cause. It is suggested to treat the root by regulating the marrow sea， and treat the branch by unblocking the meridians and dredging the collaterals， thereby balancing the mild and the urgency of the yinqiao mai and yangqiao mai. Using the "Gen （根）-Liu（溜）-Zhu （注）-Ru （入）"acupoints to bypass the various meridians and taking the gallbladder meridian according to twelve major meridians that run on both sides of the body， both of which can provide ideas for improving symptoms such as ptosis and limited eye movement caused by oculomotor nerve palsy.

Objective:To investigate the clinical characteristics and prognostic factors of extracranial malignant rhabdoid tumors (eMRTs) in children.Methods:In this retrospective case series study, a retrospective analysis was conducted on clinical data of 21 eMRT patients admitted to Children′s Hospital of Nanjing Medical University from April 2018 to January 2023 and followed up until October 30, 2023.Patients were grouped according to their gender, age, tumor origin site, clinical staging, initial lactate dehydrogenase (LDH) level, extent of tumor resection, chemotherapy regimen, and radiotherapy.The Kaplan-Meier method was used to calculate the 2-year progression-free survival rate (PFS) and overall survival rate (OS) of the patients, and the Cox regression model was used to analyze the prognostic factors.Results:Among the 21 patients with eMRTs, there were 7 males and 14 females, with the age of onset of 24 (3-138) months.Immunohistochemistry showed that all tumor tissues of the patients did not secrete integrase interactor 1 (INI-1).Among them, 13 cases originated from the kidney, and 8 cases originated from extrarenal non-central sites.At the time of diagnosis, there were 4 cases in clinical stages Ⅰ-Ⅱ, 17 cases in stage Ⅲ-Ⅳ.Thirteen patients underwent complete tumor resection surgery, 7 underwent partial resection, and 1 only underwent biopsy.Among the 13 cases of renal rhabdoid tumors, 8 cases were treated with the AVDC (Epirubicin, Vincristine, Actinomycin D, Cyclophosphamide)/ICE (Ifosfamide, Carboplatin, Etoposide) regimen, and 5 cases were treated with the protocol for nephroblastoma; among the 8 cases of extrarenal non-central rhabdoid tumors, 5 cases were treated with the AVDC/ICE regimen, and 3 cases were treated with the commonly used protocol for soft tissue sarcoma.Thirteen patients received radiotherapy.One patient received consolidation therapy with autologous stem cell transplantation following chemotherapy and radiotherapy.As of October 2023, there were 14 survivors and 7 deaths.The overall 2-year PFS and OS were 56%(95% CI: 35.7%-88.5%) and 62%(95% CI: 43.2%-89.4%), respectively.Among the patients who received the AVDC/ICE alternating chemotherapy regimen, the 2-year PFS and OS were 73%(95% CI: 47.0%-100.0%) and 79% (95% CI: 56.4%-100.0%), respectively.Univariate Cox regression analysis showed that complete tumor resection, the AVDC/ICE alternating chemotherapy, and radiotherapy were associated with a better prognosis in children (all P≤0.05).Multivariate Cox regression analysis showed that whether to receive radiotherapy was an independent risk factor affecting the overall survival in children. Conclusions:eMRTs are more common in infants and young children, with high malignancy and invasiveness.There is currently no standard treatment.Complete tumor resection combined with the AVDC/ICE alternating chemotherapy and radiotherapy may improve the prognosis of children with eMRTs.

Objective:To explore the clinical characteristics and genetic etiology of four children with Phelan-McDermid syndrome (PMS).Methods:Four children who had visited the Affiliated Women and Children′s Hospital of Ningbo University between June 2, 2022 and May 8, 2023 were selected as the study subjects. Clinical data of the children were collected. Genomic DNA was extracted from peripheral blood samples of the children and their parents and subjected to whole exome sequencing (WES). Candidate variants were verified by Sanger sequencing and quantitative PCR (q-PCR) analysis. This study was approved by the Medical Ethics Committee of the Affiliated Women and Children′s Hospital of Ningbo University (Ethics No. EC2020-048).Results:All children had presented with speech and language delays and intellectual disability. Children 3 and 4 also presented with autistic behaviors. WES showed that the children 1 and 2 had respectively carried a heterozygous c.731T>C (p.Leu244Pro) and a c.2782_2851del (p.Gly928ArgfsTer4) variant of the SHANK3 gene. Sanger sequencing confirmed that their parents did not carry the same variant, suggesting that they were de novo in origin. Children 3 and 4 had respectively harbored a 121 kb and 52.02 kb heterozygous deletion at chromosome 22q13.33, which had both encompassed the SHANK3 and ACR genes mapped to 22q13.33. q-PCR results showed that the deletion of SHANK3 and ACR genes were de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics, the c. 731T>C and c. 2782_2851del variants were predicted to be likely pathogenic (PS2+ PM2_Supporting+ PP3) and pathogenic (PVS1+ PM2_Supporting+ PS2_Supporting), respectively. Furthermore, the 52.02 kb and 121 kb heterozygous deletions in 22q13.33 were both predicted to be pathogenic (2D+ 4C, 1.05 in score; 2D+ 4C, 1 in score). Conclusion:The four children were all diagnosed with PMS by genetic testing. Above finding has enriched the phenotypic and mutational spectrum of PMS, and provided a basis for clinical diagnosis and genetic counseling for their families.

With the advances in understanding the relationships among biomaterials, the immune system and the skeletal system, the host responses elicited by implanted biomaterials can be balanced by properly designing material characteristics from the perspective of osteoimmunology. The immunoregulatory properties of bone tissue engineering scaffolds provide advantages for inducing macrophages from the proinflammatory M1 phenotype to the anti-inflammatory M2 phenotype and promoting osseointegration. Hydrogels are increasingly a focus in bone tissue engineering, and the immune response can be affected by different compositions of hydrogels, such as the sources, concentration, molecular weight, coupling with fibronectin, and the addition of cross-linking agents. Different physicochemical properties of modified hydrogels can trigger different host immune responses, modified by using soft photolithography to fabricate micropatterned hydrogels, adding enzyme-sensitive sequences, ester bonds and dynamic covalent chemistry to prevent rapid or slow degradation of the hydrogels, and adding porogens and 3D printing to modify the hydrogels with macroporous interconnective pore structures, soft and injectable hydrogels, etc. These optimized hydrogels can reduce proinflammatory factors, promote M2 macrophage polarization, and minimize foreign body reactions to evoke bone regeneration. However, the mechanism underlying the bone immune response is still poorly understood, and further study of the effects of hydrogels with different physicochemical properties on immune regulation is needed.

Background::Exercise, as the cornerstone of pulmonary rehabilitation, is recommended to chronic obstructive pulmonary disease (COPD) patients. The underlying molecular basis and metabolic process were not fully elucidated.Methods::Sprague-Dawley rats were classified into five groups: non-COPD/rest ( n = 8), non-COPD/exercise ( n = 7), COPD/rest ( n = 7), COPD/medium exercise ( n = 10), and COPD/intensive exercise ( n = 10). COPD animals were exposed to cigarette smoke and lipopolysaccharide instillation for 90 days, while the non-COPD control animals were exposed to room air. Non-COPD/exercise and COPD/medium exercise animals were trained on a treadmill at a decline of 5° and a speed of 15 m/min while animals in the COPD/intensive exercise group were trained at a decline of 5° and a speed of 18 m/min. After eight weeks of exercise/rest, we used ultrasonography, immunohistochemistry, transmission electron microscopy, oxidative capacity of mitochondria, airflow-assisted desorption electrospray ionization-mass spectrometry imaging (AFADESI-MSI), and transcriptomics analyses to assess rectal femoris (RF). Results::At the end of 90 days, COPD rats’ weight gain was smaller than control by 59.48 ± 15.33 g ( P = 0.0005). The oxidative muscle fibers proportion was lower ( P < 0.0001). At the end of additional eight weeks of exercise/rest, compared to COPD/rest, COPD/medium exercise group showed advantages in weight gain, femoral artery peak flow velocity (Δ58.22 mm/s, 95% CI: 13.85-102.60 mm/s, P = 0.0104), RF diameters (Δ0.16 mm, 95% CI: 0.04-0.28 mm, P = 0.0093), myofibrils diameter (Δ0.06 μm, 95% CI: 0.02-0.10 μm, P = 0.006), oxidative muscle fiber percentage (Δ4.84%, 95% CI: 0.15-9.53%, P = 0.0434), mitochondria oxidative phosphorylate capacity ( P < 0.0001). Biomolecules spatial distribution in situ and bioinformatic analyses of transcriptomics suggested COPD-related alteration in metabolites and gene expression, which can be impacted by exercise. Conclusion::COPD rat model had multi-level structure and function impairment, which can be mitigated by exercise.

Background Perfluorinated alkyl substances (PFAS) are a class of synthetic organic fluorides, which have adverse health effects on brain function, and limited research has been conducted on their effects on depression. Objective To assess potential correlation between serum PFAS and depression. Methods Using the 2015—2016 and 2017—2018 National Health and Nutrition Examination Survey (NHANES) datasets, 2626 subjects with complete relevant information in people ≥20 years old were selected. Logistic regression and restricted cubic splines were used to analyze the association and dose-response relationship between serum PFAS concentration and depression. Subgroup analysis was performed on sex, age, race, education level, marital status, family income to poverty ratio, moderate exercise, body mass index, and drinking status. Results Among the 2626 subjects, there were 666 patients (25.4%) with mild or above depression. After adjusting for race, education level, marital status, body mass index, moderate exercise, drinking history, cotinine, and other types of PFAS, serum perfluorooctane sulfonate (PFOS) was positively associated with the risk of depression (OR=1.85, 95%CI: 1.14, 3.02), and showed a nonlinear dose-response relationship (χ²=6.37, P_nonlinear=0.012). Perfluorononanoic acid (PFNA) was inversely associated with the risk of depression (OR=0.23, 95%CI: 0.14, 0.39), and showed a linear dose-response relationship (P_trend<0.001, χ²=35.13, P_overall<0.001). After subgroup analysis, it was found that males, 20-39 year-olds and 40-64 year-olds were more sensitive to PFNA exposure (OR=0.15, 95%CI: 0.06, 0.37; OR=0.16, 95%CI: 0.06, 0.40; OR=0.18, 95%CI: 0.08, 0.39). PFOS only showed a statistically significant health effect in people aged 20-39 years (OR=3.00, 95%CI: 1.14, 7.94). In addition, among subgroups of non-Hispanic blacks, cohabitants, current drinkers, high school graduates, and obese patients, exposure to PFAS was significantly associated with the risk of depression. Conclusion PFOS exposure may be associated with increased levels of depression, whereas PFNA exposure may be protective.

AIM: To establish individualized drug therapy strategy for patients with rejection and hyperglycemia after liver transplantation. METHODS: Clinical pharmacist collaborated with the surgeons and participated in the diagnosis and treatment of rejection and hyperglycemia after liver transplantation. Taking together liver function, therapeutic drug monitoring, drug-drug interactions between tacrolimus and wuzhi capsule, individualized drug therapy was adapted to improve the prognosis. RESULTS: The patient recovered well and survived in good health till now. CONCLUSION: It is highly suggested that clinical pharmacists actively involved in treatment of more severe and difficult-to-treat disease and design the individualized dosing regimens. This will largely contribute in reduced adverse drug reaction, improved safety and effectiveness in drug use as well as the quality of life in the "post-transplantation era".
