Objective To summarize the short-term results of valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) in the treatment of bioprosthetic valve failure after aortic valve replacement. Methods We reviewed the clinical data of patients who underwent ViV-TAVI from 2021 to 2022 in the First Affiliated Hospital of Zhengzhou University. The valve function was evaluated by echocardiography before operation, immediately after operation and 3 months after operation. The all-cause death and main complications during hospitalization were analyzed. Results A total of 13 patients were enrolled, including 8 males and 5 females with a mean age of (65.9±8.5) years, and the interval time between aortic valve replacement and ViV-TAVI was (8.5±3.4) years. The Society of Thoracic Surgeons mortality risk score was 10.3%±3.2%. None of the 13 patients had abnormal valve function after operation. The mean transvalvular pressure gradient of aortic valve was decreased (P<0.001), the peak flow velocity of aortic valve was decreased (P<0.001), and the left ventricular ejection fraction was not changed significantly (P=0.480). There were slight perivalvular leakage in 2 patients and slight valve regurgitation in 3 patients. Three months after operation, the mean transvalvular pressure difference and peak flow velocity of aortic valve in 12 patients were significantly decreased compared with those before operation (P≤0.001). Conclusion This study demonstrates that ViV-TAVI for the treatment of bioprosthetic valve failure after aortic valve replacement is associated with favorable clinical and functional cardiovascular benefits, the short-term results are satisfactory.

OBJECTIVE To evaluate the efficacy and safety of intranasal corticosteroids （INCS） combined with oral H1- antihistamine （AH） in the treatment of allergic rhinitis. METHODS A comprehensive literature search was conducted in PubMed， Embase， CNKI， and VIP database to collect randomized controlled trial （RCT） that INCS combined with AH （experimental group） versus INCS （control group） in the treatment of allergic rhinitis from the inception to December 31， 2024. After study selection， data extraction， and quality assessment， a meta-analysis was performed by using RevMan 5.3 software. RESULTS A total of 12 RCTs were included in the meta-analysis， with a total of 1 842 patients. Results of meta-analysis showed that， compared with the control group， patients in the experimental group had a greater reduction in sneezing scores， rhinorrhea scores， nasal congestion scores， nasal itching scores， total nasal symptom scores， total ocular symptom scores， and rhinoconjunctivitis quality of life questionnaire scores （P＜0.05）. The incidence of headache was lower in the experimental group （P＜0.05）； whereas there were no significant differences between the two groups in the incidence of nosebleed， dryness of the mouth and nose， drowsiness， fatigue， and total adverse events （P＞0.05）. CONCLUSIONS Compared with INCS monotherapy， the combination of INCS and oral AH provides superior efficacy and safety in the treatment of allergic rhinitis.

OBJECTIVES: To investigate the effect of moslosooflavone (MOS) for ameliorating dextran sulfate sodium (DSS)-induced colitis in mice and the underlying molecular mechanism. METHODS: C57BL/6J mice with or without DSS exposure in the drinking water were both randomized into two groups for treatment with intraperitoneal injections with MOS (200 mg/kg) or normal saline for 7 days (n=6). Disease severity of the mice was assessed by observing changes in body weight, colon length, histopathology (HE staining), intestinal barrier function, and TUNEL staining. In the in vitro studies, lipopolysaccharide (LPS)-stimulated mouse colon organoids were treated with MOS (120 μmol/L) for 24 h, and the changes in barrier dysfunction and inflammation were analyzed. Network pharmacology and Western blotting were employed to identify functional pathways and apoptotic protein regulation associated with the therapeutic effect of MOS on colitis. RESULTS: In the mouse models of DSS-indcued colitis, MOS treatment significantly reduced body weight loss, disease activity index (DAI) scores and colon shortening, ameliorated colonic histopathological changes and inflammation, and lowered pro-inflammatory cytokine levels (TNF-α, IL-1β, IL-6, and IFN-γ). MOS effectively restored intestinal barrier integrity in the mice by reducing serum FITC-dextran and I-FABP concentrations while enhancing the tight junction proteins (ZO-1 and claudin-1). In the colon organoids, MOS significantly suppressed LPS-induced inflammatory responses and epithelial barrier disruption. Western blotting revealed that MOS downregulated C-caspase-3 and BAX and upregulated Bcl-2 expressions in both models. Mechanistically, MOS suppressed PI3K and AKT phosphorylation in both DSS-treated mouse colonic tissues and LPS-stimulated organoids. CONCLUSIONS MOS alleviates experimental colitis in mice by inhibiting intestinal epithelial apoptosis via inhibiting the PI3K/AKT pathway, thereby restoring intestinal barrier integrity and reducing inflammation.

OBJECTIVES: To study the impact of SURF4 expression level on long-term prognosis of gastric cancer (GC) and biological behaviors of GC cells. METHODS: SURF4 expression level in GC and its association with long-term patient prognosis were analyzed using publicly available databases and in 155 GC patients with low and high SURF4 expressions detected immunohistochemically. The Cox proportional hazard model and Kaplan-Meier survival curves were used to analyze independent prognostic predictors of GC and the 5-year survival rate of the patients with different SURF4 expression levels. Informatics analyses were conducted to explore the correlation of SURF4 expression level with immune cell infiltration in GC, SURF4-related differential genes and their associated pathways. In cultured GC cell line HGC-27, the effects of SURF4 knockdown and overexpression on proliferation, migration, invasion and epithelial-mesenchymal transition (EMT) were investigated. RESULTS: Analysis of GEPIA dataset and immunohistochemical results suggested significant SURF4 overexpression in GC (P<0.05), which was associated with shortened 5-year survival time of the patients (χ²=38.749, P<0.001). The prognosis of GC was closely related to tumor stage T3-4, N2-3, CEA≥5 μg/L and CA19-9≥37 kU/L (P<0.05). SURF4 expression level was negatively correlated with activated B cells, NK cells and CD8⁺ effector memory T cells (P<0.05) and positively correlated with CD4⁺ T cells (P<0.05). GO and KEGG enrichment analysis suggested that SUFR4 may participate in GC carcinogenesis by promoting EMT through the tight junction pathway. In HGC-27 cells, SURF4 overexpression significantly decreased E-cadherin expression, increased N-cadherin expression, inhibited ZO-1 and claudin-1 expressions, and promoted cell proliferation, migration and invasion. CONCLUSIONS SURF4 is highly expressed in GC, and its overexpression is associated with a shortened 5-year survival of the patients possibly by enhancing tumor cell proliferation, migration and invasion via inhibiting tight junction proteins and promoting EMT.

OBJECTIVES: To investigate the role of SF3B3 in gastric cancer (GC) progression and prognosis and its possible mechanisms. METHODS: SF3B3 expression levels in pan-cancer and GC were analyzed using TIMER2.0, GEPIA, and UALCAN databases and validated using immunohistochemistry in GC tissues. Survival curves of GC patients were established using Kaplan-Meier Plotter and the data of a patient cohort our hospital. The independent risk factors for 5-year postoperative survival were identified using Cox regression, and their predictive values were evaluated using ROC analysis. SF3B3-associated biological processes were predicted by bioinformatics enrichment analyses. In GC HGC-27 cells, the effects of lentivirus-mediated SF3B3 knockdown and overexpression on cell proliferation and migration were investigated, and the changes in the key glycolytic proteins and extracellular acidification rate (ECAR) were detected. The influence of SF3B3 expression level on tumorigenesis and glycolytic protein expression in vivo were evaluated in a nude mouse xenograft model. RESULTS: High expression of SF3B3 in GC was associated with poor patient prognosis (P<0.05). The factors affecting 5-year survival outcomes following gastric oncological resection included high SF3B3 expression, a CEA level ≥5μg/L, a CA19-9 level ≥37 kU/L, tumor stage T3-4, and lymph node metastasis stage N2-3 (P<0.05). Bioinformatics analysis showed significant enrichment of SF3B3 in glycolysis. In HGC-27 cells, SF3B3 knockdown significantly inhibited while SF3B3 overexpression enhanced cell proliferation, migration, and invasion. SF3B3 knockdown obviously decreased the expressions of HK2, PKM2 and LDHA proteins and ECAR in HGC-27 cells, whereas SF3B3 overexpression produced the opposite effect. In nude mouse xenograft models, SF3B3 knockdown significantly reduced tumor mass and downregulated expression of HK2, PKM2 and LDHA proteins, and SF3B3 overexpression induced the opposite changes. CONCLUSIONS SF3B3 overexpression is associated with poor prognosis of GC patients and promotes GC cell proliferation, migration and invasion possibly by enhancing glycolysis.

Background::Atopic dermatitis (AD) affects approximately 10% of adults worldwide. CM310 is a humanized monoclonal antibody targeting interleukin-4 receptor alpha that blocks interleukin-4 and interleukin-13 signaling. This trial aimed to evaluate the efficacy and safety of CM310 in Chinese adults with moderate-to-severe AD.Methods::This multicenter, randomized, double-blind, placebo-controlled, phase 2b trial was conducted in 21 medical institutions in China from February to November 2021. Totally 120 eligible patients were enrolled and randomized (1:1:1) to receive subcutaneous injections of 300 mg CM310, 150 mg CM310, or placebo every 2 weeks for 16 weeks, followed by an 8-week follow-up period. The primary endpoint was the proportion of patients achieving ≥75% improvement in the Eczema Area and Severity Index (EASI-75) score from baseline at week 16. Safety and pharmacodynamics were also studied.Results::At week 16, the proportion of EASI-75 responders from baseline was significantly higher in the CM310 groups (70% [28/40] for high-dose and 65% [26/40] for low-dose) than that in the placebo group (20%[8/40]). The differences in EASI-75 response rate were 50% (high vs. placebo, 95% CI 31%–69%) and 45% (low vs. placebo, 95% CI 26%–64%), with both P values <0.0001. CM310 at both doses also significantly improved the EASI score, Investigator’s Global Assessment score, daily peak pruritus Numerical Rating Scale, AD-affected body surface area, and Dermatology Life Quality Index compared with placebo. CM310 treatment reduced levels of thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase, and blood eosinophils. The incidence of treatment-emergent adverse events (TEAEs) was similar among all three groups, with the most common TEAEs reported being upper respiratory tract infection, atopic dermatitis, hyperlipidemia, and hyperuricemia. No severe adverse events were deemed to be attributed to CM310. Conclusion::CM310 at 150 mg and 300 mg every 2 weeks demonstrated significant efficacy and was well-tolerated in adults with moderate-to-severe AD.Trial Registration::ClinicalTrials.gov, NCT04805411.

The traditional Chinese medicine （TCM） in pediatric care has a long history，proven efficacy，and distinctive characteristics.The China Association of Chinese Medicine has organized a series of youth salons to discuss the clinical advantages of treating diseases.Experts at this seminar proposed that the superior disease categories in pediatric TCM are significant for showcasing the unique strengths and advantages of TCM in the treatment of pediatric diseases，enhancing diagnostic and treatment levels，inheriting TCM knowledge，promoting the integration of TCM and Western medicine，and meeting patients' needs.The strengths of pediatric TCM are summed up as "having what others do not，excelling at what others have，being special in what others excel at，and ensuring safety in what others specialize in." The scope of superiority in pediatric TCM covers multiple systems，including respiratory，digestive，endocrine，psychological，and dermatological systems.This article summarized the advantages of TCM in treating 13 diseases discussed in the salon，such as upper respiratory tract infections，coughs，pneumonia，allergic rhinitis，bronchial asthma，atopic dermatitis，functional dyspepsia，functional constipation，enuresis，marginal short stature，simple obesity，attention deficit hyperactivity disorder，and tic disorders.The overall advantages were reflected in three aspects：First，the holistic concept and treatment based on syndrome differentiation in TCM highlight the advantage of treating the root causes of diseases，making the treatment methodical and precise.Second，most traditional Chinese herbs are natural and have strong safety profiles.Third，TCM treatment methods are abundant，especially the external treatment methods，which are widely used in pediatrics，highly accepted by parents，and have definite efficacy，as well as good safety and compliance.
