Objective To summarize the clinical efficacy of modified Morrow surgery in the treatment of hypertrophic obstructive cardiomyopathy. Methods A retrospective analysis was conducted on the clinical data of patients with hypertrophic obstructive cardiomyopathy treated with modified Morrow surgery at Zhongshan Hospital Affiliated to Fudan University from 2020 to 2023. Results A total of 318 patients were enrolled, including 156 males and 162 females, with an average age of (55.6±13.1) years. Preoperative echocardiography showed a mean interventricular septal thickness of (18.1±3.8) mm, peak left ventricular outflow tract pressure difference of (86.4±24.9) mm Hg. The surgery time was (162.3±51.0) min, extracorporeal circulation time was (80.9±31.0) min, and aortic occlusion time was (44.8±20.8) min. After the surgery, transesophageal echocardiography showed that the interventricular septal thickness was (11.0±1.8) mm and left ventricular outflow tract peak pressure difference was (9.4±5.1) mm Hg. The incidence rate of postoperative complete left bundle branch block was 45.3%, Ⅲ° atrioventricular block was 3.8%, and postoperative newly developed atrial fibrillation was 3.1%. The postoperative hospital stay was (6.6±4.9) days, and one perioperative death occurred, with a mortality rate of 0.3%. The follow-up time was (10.3±9.4) months, during which the transthoracic echocardiography revealed a ventricular septal thickness of (12.9±2.9) mm and a peak left ventricular outflow tract pressure difference of (13.9±10.0) mm Hg. Conclusion The modified Morrow procedure for the treatment of hypertrophic obstructive cardiomyopathy is safe and effective, with good results in the short and medium term.

With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

Objective To explore the principle of antibacterial drug therapy and the strategy of program optimization in elderly patients with Helicobacter pylori（Hp）. Methods The common therapeutic regimen of Hp was summarized, and the better therapeutic regimen of elderly Hp patients was screened ultimately. Results Amoxicillin and cefuroxime were relatively safe compared with other recommended antibacterial drugs. Using other commonly antibiotics for Hp should pay attention to the disease of patients and current drug. Conclusion Elderly patients usually suffered from a variety of diseases and required multiple drugs. The application of therapeutic regimen for elderly patients with Hp should be supposed to fully weigh the risks and benefits.

Objective: To deeply explore the systemic management dilemmas affecting patients with chronic periodontitis in underdeveloped regions, providing practical pathways for achieving oral health equity. Methods: This study has been reviewed and approved by the Medical Ethics Committee, and written informed consent was obtained from the participants. Based on a comprehensive design integrating literature review and theory, an interview guide was developed. Using purposive sampling, semi-structured interviews were conducted with 20 patients diagnosed with chronic periodontitis who were from underdeveloped regions and attended the Stomatological Hospital of Southern Medical University between November 2025 and February 2026. The sample size was determined by data saturation. Data analysis employed Colaizzi’s seven-step method. Results: Through interview with 20 participants, three core themes were extracted, encompassing eight sub-themes: individual cognitive-behavioral dilemmas (cognitive limitations and passive coping, inefficient and superficial self-management, and economic and psychological barriers to seeking care); systemic and environmental structural obstacles (distrust in primary healthcare capabilities, and the limited buffering effect and constraints of medical insurance); and the need for health empowerment and support systems (authoritative knowledge and management skill guidance, aspirations for access to high-quality specialized medical resources, and sustained and reminder-based remote support). Conclusion Patients with chronic periodontitis in underdeveloped regions face a multidimensional dilemma composed of limited health literacy, poor adherence to health behaviors, weak primary care service capacity, uneven medical insurance coverage, and insufficient high-quality specialized medical resources. Patients’ health literacy should be advanced through innovative health education, primary care capacity should be strengthened for periodontal disease prevention and treatment, and it is recommended to prioritize the inclusion of initial periodontal therapy in outpatient coordination or chronic disease management, and a remote medical support system based on digital technology should be established.

ObjectiveTo investigate the mRNA expression profile and clinical significance of the RAB24 gene in hepatocellular carcinoma （HCC） based on multi-source database including The Cancer Genome Atlas （TCGA） and clinical cohort validation. MethodsData from TCGA （n=424） were utilized to evaluate the prognostic value of RAB24 expression via Kaplan-Meier analysis and Cox regression models. An independent clinical cohort comprising 90 HCC and 30 paracancerous tissues was established to validate protein expression and histopathological features through immunohistochemistry （IHC） and routine histological staining. The TIMER database was employed to analyze the association between RAB24 and the tumor microenvironment （TME）. Furthermore， integrated with LinkedOmics， GSEA and GSVA algorithms were used to quantitatively characterize the core molecular pathways regulated by RAB24. ResultsThe mRNA expression level of RAB24 in HCC was significantly higher than that in non-tumor liver tissues （P<0.05）. Kaplan-Meier analysis revealed that the overall survival （OS） of patients in the RAB24 low-expression group was significantly longer compared to the high-expression group （HR=1.570， Log-rank P=0.01）. Cox proportional hazards regression analysis demonstrated that RAB24 expression （HR=1.480， P=0.028）， T stage （HR=2.949， P<0.001）， M stage （HR=4.077， P=0.017）， and tumor residual status （HR=2.317， P<0.001） were independent prognostic factors for HCC. RAB24 expression was highly correlated with alpha-fetoprotein （AFP） levels and immune infiltration levels （P<0.01）， and showed a significant， low-level positive correlation with the TP53 gene （Rho=0.31， P<0.01）. Quantitative analysis of the RAB24 protein in clinical samples validated that RAB24 expression in HCC tissues was significantly elevated compared to non-tumor liver tissues （P<0.05）. TIMER analysis confirmed that RAB24 expression was highly associated with the infiltration of multiple immune cells （such as B cells and NK cells）， as well as stromal and tumor purity scores in tumor tissues （P<0.01）. GSEA/GSVA enrichment revealed that the P53， MYC， and mTORC1 signaling pathways were activated in the RAB24 high-expression group； correlation analysis confirmed that the RAB24 expression level exhibited a significant， low-level positive correlation with the ribosome pathway activity score （r=0.23， P<0.01）. ConclusionsThe RAB24 gene， as a poor prognostic factor for HCC patients， is a potential biomarker for HCC diagnosis， treatment and prognosis. The study is expected to lay a theoretical foundation for the precise diagnosis and treatment of clinical HCC.

This study aims to comprehensively analyze the material basis of toad visceral oil(hereafter referred to as toad oil), and explore the pharmacological effect of toad oil on atopic dermatitis(AD). Ultra-high performance liquid chromatography-linear ion trap/orbitrap high-resolution mass spectrometry(UHPLC-LTQ-Orbitrap-MS) and gas chromatography-mass spectrometry(GC-MS) were employed to comprehensively identify the chemical components in toad oil. The animal model of AD was prepared by the hapten stimulation method. The modeled animals were respectively administrated with positive drug(0.1% hydrocortisone butyrate cream) and low-and high-doses(1%, 10%) of toad oil by gavage. The effect of toad oil on AD was evaluated with the AD score, ear swelling rate, spleen index, and pathological section results as indicators. A total of 99 components were identified by UHPLC-LTQ-Orbitrap-MS, including 14 bufadienolides, 7 fatty acids, 6 alkaloids, 10 ketones, 18 amides, and other compounds. After methylation of toad oil samples, a total of 20 compounds were identified by GC-MS. Compared with the model group, the low-and high-dose toad oil groups showed declined AD score, ear swelling rate, and spleen index, alleviated skin lesions, and reduced infiltrating mast cells. This study comprehensively analyzes the chemical composition and clarifies the material basis of toad oil. Meanwhile, this study proves that toad oil has a good therapeutic effect on AD and is a reserve resource of traditional Chinese medicine for external use in the treatment of AD.

Objective To explore the mechanism of ligustrazine(LC)in improving chemothera-py-induced neuropathic pain(CINP)by regulating the Ras homolog gene family member A(RhoA)/p38 mitogen-activated protein kinase(p38MAPK)signaling pathway.Methods Sixty SD rats were randomly divided into five groups:control group(Con group),model group(Model group),low-dose LC group(L-LC group),high-dose LC group(H-LC group),and high-dose LC+lysophosphatidic acid group(H-LC+LPA group),with 12 rats in each group.Pain behavioral tests were performed on the rats.Neuronal lesions were observed using hematoxylin-eosin staining.The levels of reactive oxy-gen species(ROS),malondialdehyde(MDA),superoxide dismutase(SOD),tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1β),and interleukin-10(IL-10)were detected using enzyme-linked immunosorbent assay(ELISA).The expression levels of apoptosis,autophagy,and RhoA/p38MAPK signaling pathway-related proteins were detected using western blot.The apoptosis level in the spinal dorsal horn tissue was detected using TUNEL.Results On 3,5,and 7 d after surgery,the me-chanical withdrawal threshold(MWT)and thermal withdrawal latency(TWT)in the Model group were lower than those in the Con group.The MWT and TWT in the L-LC group and H-LC group were higher than those in the Model group,and the MWT and TWT in the H-LC group were higher than those in the L-LC group(P＜0.05).The MWT and TWT in the H-LC+LPA group were lower than those in the H-LC group(P＜0.05).Compared with the Con group,the expression levels of IL-10,SOD,B-cell lymphoma-2(Bcl-2),autophagy-related protein(Beclin-1),BNIP protein,and LC3-Ⅱ/LC3-Ⅰ were decreased in the Model group,while the levels of TNF-α,IL-1β,ROS,MDA,caspase-1,Bax,RhoA,phosphorylated p38 mitogen-activated protein kinase(P-p38MAPK)/p38MAPK protein expression,and apoptosis rate were increased(P＜0.05).Compared with the Model group,the expression levels of IL-10,SOD,Bcl-2,Beclin-1,BNIP protein,and LC3-Ⅱ/LC3-Ⅰ were in-creased in the L-LC group and H-LC group,while the levels of TNF-α,IL-1β,ROS,MDA,caspase-1,Bax,RhoA,P-p38MAPK/p38MAPK protein expression,and apoptosis rate were de-creased in a dose-dependent manner(P＜0.05).Compared with the H-LC group,the MWT,TWT,expression levels of IL-10,SOD,Bcl-2,Beclin-1,BNIP protein,and LC3-Ⅱ/LC3-Ⅰ were significantly decreased in the H-LC+LPA group,while the levels of TNF-α,IL-1β,ROS,MDA,caspase-1,Bax,RhoA,P-p38MAPK/p38MAPK protein expression,and apoptosis rate were in-creased(P＜0.05).Conclusion LC may alleviate the neuropathic disease symptoms in CINP rats by inhibiting the RhoA/p38MAPK signaling pathway,thereby inhibiting oxidative stress,neuroin-flammation,and apoptosis,and promoting autophagy.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Through analyzing the every textual research literature on the origin of the location method of ashi points, it is pointed out that the location method of ashi points has been generalized. It is known through systematic research and theoretical identification that this method refers to the simple way to locate the points, originated from the folk, and it is widely used to find the sites for pain relief when compared to the official education of meridians and acupoints, as well as treatment. At the time with the shortage of medical services and supplies, the poor people had no alternative, which results in a certain limitation. Modern acupuncture practitioners must associate ashi points with the acupoints of fourteen meridians and the extraordinary points in clinical practice, and deepen the exploration with modern medical knowledge and technology adopted.
