Naringenin(NAR), a naturally derived flavonoid compound, has attracted considerable attention due to its multiple pharmacological activities, including anti-inflammatory, antioxidant, anti-allergic, and antibacterial effects. This article systematically reviews the experimental and preclinical research progress of naringenin in common ocular diseases, with a focus on its potential applications in corneal neovascularization, dry eye disease, glaucoma, cataracts, and retinal disorders. Existing studies indicate that naringenin can exert protective effects on ocular tissues by regulating multiple signaling pathways, such as inhibiting inflammatory responses, alleviating oxidative stress-induced damage, and suppressing angiogenesis, thereby demonstrating promising therapeutic potential. Meanwhile, this review summarizes the research progress of ocular biopharmaceutical formulations, including naringenin eye drops, and highlights current limitations, such as its poor solubility and low bioavailability, which hinder its clinical translation. Naringenin shows unique advantages in the treatment of ocular diseases. However, future research should further clarify its molecular mechanisms, optimize drug delivery systems to enhance ocular bioavailability, and conduct well-designed clinical trials, aiming to provide new strategies and insights for the treatment of ocular diseases.

Objective To compare the clinical efficacy between liposuction combined with circumareolar small incision and three-port endoscopic surgery for the treatment of Simon Ⅱ gynecomastia (GYN). Methods Comparative case data of 120 patients with GYN were retrospectively analyzed, 61 patients in the open group underwent circumareolar small incision mastectomy after liposuction, and 59 patients in the endoscopic group underwent three-port endoscopic mastectomy after liposuction. The two groups were compared in terms of surgery-related indexes, occurrence of postoperative complications and patient satisfaction. Results The unilateral operation time of the open group was shorter than that of the endoscopic group, the unilateral gland resection weight in the open group was more than that in the endoscopic group, the hospitalization cost of the open group was less than that of the endoscopic group (all P<0.01). There was no significant difference in unilateral liposuction volume, drainage volume on the first postoperative day, and time to drain removal between the two groups (P>0.05). The incidence of complications in the open group and the endoscopic group were 8.2% and 13.6% respectively, and there was no significant difference between the two groups (P>0.05). The difference in the overall satisfaction scores between the two groups was not statistically significant (P>0.05). Conclusions Liposuction combined with circumareolar small incision or three-port endoscopic surgery both has good cosmetic effects in the treatment of Simon Ⅱ GYN. The operation with circumareolar small incision is simple, has a shorter operation time, costs less, and does not require special equipment, which is suitable for promotion and application in medical institutions.

Intertrochanteric fractures of the femur are common hip fractures in the elderly. Their treatment goals include reducing incidence of complications, improving quality of life and increasing survival rate for the patients. Compared with traditional internal fixation, hip arthroplasty shows certain advantages in the primary treatment of intertrochanteric fractures of the femur and the revision following failure of internal fixation. It enables patients to do early weight-bearing activities to effectively improve their joint function, and reduces the risk of complications associated with long-term bed rest. However, at present, there has been no unified consensus in the academic community regarding the treatment plan of hip arthroplasty for intertrochanteric fractures of the femur. This paper mainly reviews the research progress in such aspects as indications of hip arthroplasty for primary intertrochanteric fractures of the femur and for revision after failure of internal fixation, anatomical and biomechanical characteristics of the femoral trochanter, principles for selection of types and models of joint prosthesis, key operative techniques like intraoperative fixation of bone fragments and prosthesis implantation, and methods of peri-operative comprehensive assessment.

Immunodeficiency is one of the main clinical phenotypes of diseases caused by germline loss-of-function variants in the nuclear SET domain-containing protein 2 (NSD2)-coding gene. NSD2 gene plays an important regulatory role in the immune system, but the underlying mechanism has not been fully elucidated. In recent years, great progress has been made regarding the function of NSD2 gene in the immune system including involving in B cell differentiation and development, promoting germinal center B cell activation and antibody production, recruiting regulatory T (Treg) cells to the maternal-fetal interface to induce maternal-fetal immune tolerance, and up-regulating MHCⅠ expression in tumor cells to trigger tumor immunity. This article mainly reviews the research progress in the regulatory function of NSD2 gene in the above immune processes.

Objective To analyze the factors affecting the prevalence of hyperuricemia(HUA)in an island troop.Methods A total of 1 113 soldiers stationed on an island from December 2021 to December 2022 were selected as research objects by cluster sampling.Their lifestyle and health information were collected.Physical examination and laboratory detection were conducted.Multivariate logistic regression was used to analyze the influencing factors of HUA.Results The prevalence rate of HUA was 21.02%(234/1 113).There were significant differences in the body mass index(BMI),waist-to-hip ratio,triglyceride,alanine aminotransferase,and creatinine between the soldiers with hyperuricemia and the soldiers with normal blood uric acid(P<0.05).Multivariate logistic regression analysis showed that BMI≥24(OR=1.49,95%CI:1.09-2.05),abnormal liver function(OR=2.26,95%CI:1.31-3.92),and dyslipidemia(OR=1.46,95%CI:1.01-2.12)were positively correlated with hyperuricemia;age>30 years old(OR=0.59,95%CI:0.37-0.93)and exercise time>1 h per week(OR=0.46,95%CI:0.22-0.97)were negatively correlated with HUA.Conclusion The prevalence rate of hyperuricemia is at a high level in an island troop.BMI≥24,age≤30 years old,exercise time≤1 h per week,abnormal liver function,and dyslipidemia are the risk factors for HUA.Prevention and control measures should be taken as early as possible for the soldiers with these risk factors.

The underlying cause of low response rates to existing immunotherapies is that tumor cells dominate tumor immune escape through surface antigen deficiency and inducing tumor immunosuppressive microenvironment (TIME). Here, we proposed an in situ tumor cell engineering strategy to disrupt tumor immune escape at the root by restoring tumor cell MHC-I/tumor-specific antigen complex (MHC-I/TSA) expression to promote T-cell recognition and by silencing tumor cell CD55 to increase the ICOSL⁺ B-cell proportion and reverse the TIME. A doxorubicin (DOX) and dual-gene plasmid (MAC pDNA, encoding both MHC-I/ASMTNMELM and CD55-shRNA) coloaded drug delivery system (LCPN@ACD) with tumor targeting and charge/size dual-conversion properties was prepared. LCPN@ACD-induced ICD promoted DC maturation and enhanced T-cell activation and infiltration. LCPN@ACD enabled effective expression of MHC-I/TSA on tumor cells, increasing the ability of tumor cell recognition and killing. LCPN@ACD downregulated tumor cell CD55 expression, increased the proportion of ICOSL⁺ B cells and CTLs, and reversed the TIME, thus greatly improving the efficacy of αPD-1 and CAR-T therapies. The application of this in situ tumor cell engineering strategy eliminated the source of tumor immune escape, providing new ideas for solving the challenges of clinical immunotherapy.

Mitochondrial DNA (mtDNA) acts as a damage-associated molecular pattern to activate the stimulator of interferon genes (STING) signaling in macrophages, promoting tissue inflammation. However, its role in acute myocardial infarction (AMI) remains unclear. Macrophage-specific Sting1 knockout mice were used to validate STING's pathological role in AMI. Cardiac and liver mtDNA were used to activate macrophages in co-culture systems with cardiomyocytes to assess fibrosis and hypertrophy. Panaxatriol saponin (PTS) was tested for its ability to block mtDNA-driven macrophage activation and subsequent cardiomyocyte damage. STING-PTS binding ability was analyzed. AMI rats received PTS to evaluate its effects on myocardial inflammation and ventricular remodeling. In vivo, macrophage-specific Sting1 knockout reduced myocardial inflammation and injury after AMI. In vitro, mtDNA-activated macrophages induced cardiomyocyte fibrosis and hypertrophy through STING signaling. PTS suppressed mtDNA-driven macrophage activation by directly binding STING, thereby blocking inflammatory cascades. In AMI rats, PTS treatment attenuated acute inflammation and reversed ventricular remodeling. These findings establish the mtDNA-STING axis in macrophages as a critical driver of post-AMI inflammation and identify pharmacological STING inhibition with PTS as a promising therapeutic strategy. The study bridges genetic validation with translational applications, highlighting macrophage STING as a novel target for ischemic heart disease management.

With the rapid advancement of vaccines, the research and application of vaccine adjuvants have garnered significant attention. Despite the development of numerous vaccine adjuvants, their applications in human vaccines remain limited due to either insufficient efficacy or severe side effects. Consequently, there is growing interest in developing bioactive compounds derived from traditional Chinese medicines (TCMs) as vaccine adjuvants, owing to their natural biocompatibility, diversity, and safety. Here, we systematically review the current application status and potential value of TCM-based bioactive compounds in vaccine adjuvants. Firstly, we elaborate on the types and characteristics of active ingredients, such as polysaccharides, saponins, flavonoids, acids, and alkaloids. The mechanisms by which these compounds function as vaccine adjuvants are then discussed, including their roles in enhancing humoral immunity, cellular immunity, and relieving the immune suppression in the microenvironment. Additionally, we summarize the current strategies for structural modification and platform optimization to adapt to different application scenarios. Finally, we offer insights into the future development directions for these potential adjuvants, highlighting research priorities, technical approaches, and application prospects. In conclusion, natural vaccine adjuvants derived from TCMs present broad application prospects and hold promise for future vaccine development.

OBJECTIVES: We propose a novel deep learning segmentation algorithm (DSRF) based on multi-scale supervision and residual feedback strategy for precise segmentation of the optic chiasm and optic nerves in CT images of nasopharyngeal carcinoma (NPC) patients. METHODS: We collected 212 NPC CT images and their ground truth labels from SegRap2023, StructSeg2019 and HaN-Seg2023 datasets. Based on a hybrid pooling strategy, we designed a decoder (HPS) to reduce small organ feature loss during pooling in convolutional neural networks. This decoder uses adaptive and average pooling to refine high-level semantic features, which are integrated with primary semantic features to enable network learning of finer feature details. We employed multi-scale deep supervision layers to learn rich multi-scale and multi-level semantic features under deep supervision, thereby enhancing boundary identification of the optic chiasm and optic nerves. A residual feedback module that enables multiple iterations of the network was designed for contrast enhancement of the optic chiasm and optic nerves in CT images by utilizing information from fuzzy boundaries and easily confused regions to iteratively refine segmentation results under supervision. The entire segmentation framework was optimized with the loss from each iteration to enhance segmentation accuracy and boundary clarity. Ablation experiments and comparative experiments were conducted to evaluate the effectiveness of each component and the performance of the proposed model. RESULTS: The DSRF algorithm could effectively enhance feature representation of small organs to achieve accurate segmentation of the optic chiasm and optic nerves with an average DSC of 0.837 and an ASSD of 0.351. Ablation experiments further verified the contributions of each component in the DSRF method. CONCLUSIONS The proposed deep learning segmentation algorithm can effectively enhance feature representation to achieve accurate segmentation of the optic chiasm and optic nerves in CT images of NPC.
