ObjectiveTo establish a mouse model of particulate matter 2.5 (PM2.5)-induced dry eye and investigate whether Chufeng Yisuntang can ameliorate the PM2.5-induced ocular surface damage by regulating the reactive oxygen species (ROS)/p38 mitogen-activated protein kinase (p38 MAPK) signaling pathway. MethodsSixty 8-week-old male C57BL/6J mice were used. Ten were randomly selected as the control group. The remaining 50 mice received topical instillation of 1 drop (0.1 mL) of 5 g·L-1 PM2.5 suspension in both eyes, four times daily. Successfully modeled mice were randomized into four groups (n=10): Model, p38 MAPK inhibitor, Chufeng Yisuntang, and combination (Chufeng Yisuntang at 7.3 g·kg-1 + p38 MAPK inhibitor SB203580 at 5 mg·kg-1). Chufeng Yisuntang was administered via gavage, and the inhibitor group via intraperitoneal injection. The control and model groups received equal volumes of distilled water by gavage. All treatments lasted for 4 weeks. General conditions were dynamically observed. Tear secretion, tear film break-up time, and corneal fluorescein staining were assessed. After intervention for 4 weeks, hematoxylin and eosin (HE) staining was used to examine the histopathological changes. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure serum levels of ROS, malondialdehyde (MDA), superoxide dismutase (SOD) 1, and SOD2. Western blot and Real-time PCR were employed to determine the protein and gene levels, respectively, of p38 MAPK, B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), and cysteinyl aspartate-specific proteinase-3 (Caspase-3) in the corneal tissue. ResultsCompared with the control group, the model group exhibited reduced tear secretion volume and tear film breakup time, along with increased corneal fluorescein staining scores (P<0.01). Compared with the model group, the Chufeng Yisuntang group, p38 MAPK inhibitor group, and combination group demonstrated increased tear secretion volume and tear film breakup time, along with decreased corneal fluorescein staining scores (P<0.01). HE staining revealed that compared with the control group, the model group exhibited marked increases in corneal epithelial cell layers and epithelial thickness, along with reduced meibomian gland acini and intensely stained, densely packed nuclei around the acini. Compared with the model group, the Chufeng Yisuntang group, p38 MAPK inhibitor group, and combination group showed intact corneal structure, improved cell morphology, and reduced damage severity. ELISA revealed elevated ROS and MDA levels (P<0.01) and decreased SOD1 and SOD2 levels (P<0.01) in the model group compared with the control group. Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination lowered ROS and MDA levels (P<0.01), while raising SOD1 and SOD2 levels (P<0.05, P<0.01). Western blot revealed that compared with the control group, the model group exhibited increased protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01) and reduced protein level of Bcl-2 (P<0.01). Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination down-regulated the protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), while up-regulating the protein level of Bcl-2 (P<0.01). Compared with the Chufeng Yisuntang group, the combination group exhibited decreased protein levels of p38 MAPK, Bax, and Caspase-3 (P<0.01) and increased protein level of Bcl-2 (P<0.01). Real-time PCR revealed that compared with the control group, the model group exhibited upregulated mRNA levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), and downregulated mRNA level of Bcl-2 (P<0.01). Compared with the model group, Chufeng Yisuntang, p38 MAPK inhibitor, and the combination down-regulated the mRNA levels of p38 MAPK, Bax, and Caspase-3 (P<0.01), while up-regulating the mRNA level of Bcl-2 (P<0.05, P<0.01). Compared with the Chufeng Yisuntang group, the combination group exhibited decreased mRNA levels of p38 MAPK, Bax, and Caspase-3 expression (P<0.05, P<0.01) and increased mRNA level of Bcl-2 (P<0.01). ConclusionChufeng Yisuntang may partially protect against PM2.5-induced corneal injury by inhibiting the ROS/p38 MAPK pathway, enhancing antioxidant defense, and reducing epithelial apoptosis.

OBJECTIVE:
To explore the serological and molecular genetic characteristics of a family with subtype B(A)06.
METHODS:
A neonatal hyperbilirubinemia patient who was treated at Henan Children's Hospital on June 15, 2023 due to "yellowing of the skin and gradual aggravation", and was found to have inconsistent ABO forward and reverse typing through blood type testing, was selected as the research subject. Six milliliters of peripheral blood were collected from the newborn and her family members (grandfather, grandmother, father, mother and aunt) respectively. ABO blood group identification was performed by the blood group serological method. Human genomic DNA was extracted using the nucleic acid extraction or purification reagent BT-01. ABO gene exons 2 to 7 were amplified by PCR. The PCR-specific products that were successfully amplified were sequenced by Sanger method. Taking ABO*A1.01 as the reference sequence, the ABO gene sequences of the newborn and her family members were analyzed to determine the ABO genotype. The procedures followed in this study were approved by the Ethics Committee of Henan Children's Hospital (Ethics No.: 2022-K-L036).
RESULTS:
The serological results of ABO blood group showed that the newborn, her grandfather, father and aunt were all incompatible with the forward and reverse typing. The blood group phenotype of the newborn was AwB or B(A), the blood group phenotype of the grandfather was A2B or B(A), the blood group phenotype of the father and aunt were A2B, and the blood group phenotype of the grandmother and mother were both O. The screening test results of hemolytic disease of the newborn showed that the free test detected IgG anti-A1 antibody, while the elution test, direct antiglobulin test and antibody screening results were all negative. The Sanger sequencing results showed that the newborn had variations of c.261delG, c.297A>G, c.526C>G, c.657C>T, c.703G>A, c.796C>A and c.930G>A. Her grandfather had variations of c.297A>G, C.526C>G, c.657C>T, c.703G>A, c.796C>A, c.803G>C and c.930G>A. Her grandmother had variations of c.106G>T, c.188G>A, c.189C>T, c.220C>T, c.261delG, c.297A>G, c.646T>A, c.681G>A, c.771C>T and c.829G>A. Her father and aunt had variations of c.106G>T, c.188G>A, c.189C>T, c.220C>T, c.261delG, c.297A>G, c.526C>G, c.646T>A, c.657C>T, c.681G>A, c.703G>A, c.771C>T, c.796C>A, c.829G>A and c.930G>A. Her mother had variations of c.106G>T, c.188G>A, c.189C>T, c.220C>T, c.261delG, c.297A>G, c.646T>A, c.681G>A, c.771C>T, and c.829G>A.The genotype of the newborn was ABO*BA.06/ABO*O.01.01, her grandfather was ABO*BA.06/ABO*B.01, her grandmother was ABO*O.01.02/ABO*O.01.02, her father and aunt were ABO*BA.06/ABO*O.01.02, and her mother was ABO*O.01.01/ABO*O.01.02. The ABO*BA.06 allele of the newborn, grandfather, father and aunt was caused by the c.803C>G variation in exon 7 based on the ABO*B.01 allele. The ABO*BA.06 allele can be stably inherited in this family.
CONCLUSION
The blood type of neonatal patients with B(A)06 subtype can be accurately determined by gene sequencing technology. If the forward typing is ≤ 3+ agglutination intensity in newborn ABO blood group identification, the reason should be carefully analyzed, and the molecular biology technology and family gene sequencing results should be used to jointly determine if necessary.

As one of the most common malignant tumors, digestive system tumors exhibit an increase in the incidence and mortality year by year. Its pathogenesis is complex, making it difficult to carry out early prevention. Autophagy is a process in which cells use lysosomes to degrade their organelles and macromolecules to maintain cellular homeostasis under the regulation of autophagy-related genes. Cellular autophagy has a dual regulatory effect on the tumor microenvironment, which always affects the occurrence and development of digestive system tumors. Therefore, the effect and mechanism of action of cellular autophagy on digestive system tumors have become a hot topic in tumor therapy in recent years. Meanwhile, the remarkable research results of targeted autophagy drugs indicate that cellular autophagy may become an important target for anti-digestive system tumors. Traditional Chinese medicine (TCM) has been widely used in the comprehensive treatment of digestive system tumors with good efficacy. A variety of active ingredients in TCM, such as flavonoids, glycosides, terpenoids, quinones, and alkaloids, can increase the expression of autophagy-associated proteins microtubule-associated protein 1 light chain 3 (LC3)Ⅱ/Ⅰ, autophagy-related gene (ATG)5, ATG7, inhibit the expression of autophagy-related protein p62 , and induce autophagy in digestive system tumor cells, thereby exerting the anti-digestive system tumor effect. By summarizing the research results in recent years on the modulation of cell autophagy by active ingredients in TCM to fight against digestive system tumors, this paper analyzed the relevant signaling pathways, regulatory factors, and functional characteristics of cell autophagy modulation, so as to elucidate the mechanism by which active ingredients of TCM induce autophagy and to provide ideas and references for clinical application.

Breast cancer prevention and treatment have become major issues that urgently need to be addressed in the field of global public health. As a key pathological transitional stage in the progression of breast cancer, preneoplastic breast cancer (PBC) carries a significant risk of clinical transformation. Effective intervention in the progression of PBC is of great clinical significance in preventing the occurrence of breast cancer. Pathological studies have shown that abnormal angiogenesis is a key mechanism driving the transformation of PBC into breast cancer. Vascular endothelial growth factor (VEGF), as a core regulatory molecule that promotes angiogenesis, plays a pivotal role in this process. The malignant transformation of PBC is closely associated with the abnormal activation of the VEGF-mediated pro-angiogenic network. Although modern medicine has achieved certain therapeutic effects through surgery and endocrine therapy, clinical limitations such as invasiveness, drug resistance, and adverse reactions still exist. Recent studies have demonstrated that the VEGF signaling system mediates the phosphatidylinositol 3-kinase-protein kinase B (PI3K/Akt) signaling pathway and the mitogen-activated protein kinase (MAPK) pathway. In addition, the hypoxia-inducible factor-1α (HIF-1α)/VEGF signaling pathway and the delta-like ligand 4 (DLL4)/Notch receptor 1 (Notch1) signaling pathway, together with other pathways, form a complex regulatory network that plays a central role in angiogenesis during PBC. Traditional Chinese medicine (TCM), characterized by multi-component synergy, multi-pathway regulation, and high safety, demonstrates significant advantages in inhibiting pathological angiogenesis and blocking PBC progression by targeting the VEGF signaling pathway. From the perspective of VEGF pathway regulation, this paper systematically reviews the latest research progress on TCM in inhibiting angiogenesis and intervening in PBC, and discusses its mechanisms and application value in the early prevention and treatment of PBC, with the aim of providing references for optimizing clinical intervention strategies for PBC.

Gastrointestinal tumors (GTs), including colorectal cancer, gastric cancer, liver cancer, pancreatic cancer, and esophageal cancer, are increasing in incidence worldwide and have become one of the major diseases threatening human health. Tumor stem cells (TSCs), an undifferentiated subpopulation within tumor tissues, possess biological characteristics such as self-renewal, multidirectional differentiation, high tumorigenicity, and resistance to radiochemotherapy. They play an important role in the occurrence, progression, recurrence, and metastasis of GTs and have increasingly become a research hotspot in GT treatment. Although modern medicine has made remarkable progress, there remain many problems in therapeutic approaches targeting TSCs. In this context, traditional Chinese medicine (TCM), with its favorable safety profile and multi-target mechanisms, has shown potential advantages and value in regulating TSCs. It can reduce TSC drug resistance, enhance the sensitivity of tumor cells to chemotherapeutic agents, inhibit tumor growth and metastasis, and has shown unique advantages in improving the quality of life and prolonging the survival of GT patients. Studies have found that active components of Chinese medicine, such as terpenoids, polyphenols, flavonoids, glycosides, and quinones, and Chinese medicine compound formulas, including Zuojin pills, Sijunzi decoction, Biejiajian pills, and Xuanfu Daizhe decoction, can inhibit TSCs-related signaling pathways such as the Notch signaling pathway, the Wnt/β-catenin signaling pathway, the phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt) signaling pathway, and the Hippo signaling pathway. They also reduce the expression of TSC surface markers, including sex-determining region Y-box 2 (SOX2), sex-determining region Y-box 9 (SOX9), octamer-binding transcription factor 4 (OCT4), prominin-1 (CD133), cluster of differentiation 44 (CD44), cluster of differentiation 24 (CD24), and thyroid transmembrane protein 1 (CD90), thereby hindering TSC differentiation, accelerating their metabolic processes, improving the tumor microenvironment, and consequently inhibiting GT growth. This study collects and analyzes recent research on the regulation of TSCs by TCM in the treatment of GT, aiming to provide a new theoretical basis for tumor therapy with TCM, expand its application in the comprehensive treatment of GT, and offer new therapeutic ideas and methods for clinical practice.

Objective:To investigate the clinical efficacy of artificial humeral head replacement versus locking plate internal fixation in the treatment of comminuted proximal humeral fractures in older adult patients. Methods:A total of 30 older adult patients with proximal humeral comminuted fractures, admitted to Beifang Hospital, Huainan Xinhua Medical Group from January 2022 to December 2024, were included in this study. A prospective randomized controlled study design was used. The patients were divided into an observation group and a control group using a random number table method, with 15 patients in each group. The observation group underwent artificial humeral head replacement surgery, while the control group received internal fixation with a proximal humeral locking plate. Clinical treatment outcomes, shoulder joint function recovery, and complications were observed and compared between the two groups.Results:The intraoperative blood loss in the observation group was less than that in the control group [(182.24 ± 24.36) mL vs. (245.17 ± 46.08) mL]. The surgery duration [(71.84 ± 7.52) minutes vs. (93.67 ± 12.50) minutes] and hospital stay [(11.37 ± 1.89) days vs. (13.52 ± 2.67) days] were also significantly shorter in the observation group compared with the control group ( t = 4.68, 5.80, 2.55, all P < 0.05). The range of motion in the shoulder joint was greater in the observation group compared with the control group [forward elevation: (94.47 ± 7.66) ° vs. (86.14 ± 5.15) °, external rotation: (61.35 ± 6.57) ° vs. (52.40 ± 4.82) °, and internal rotation: (74.35 ± 4.80) ° vs. (62.76 ± 3.59) °]. The total Constant-Murley score was higher in the observation group [(92.91 ± 10.58) vs. (76.29 ± 7.48)], and the rate of excellent recovery of shoulder function was also higher in the observation group [73.33% (11/15) vs. 53.33% (8/15)] compared with the control group. The incidence of complications was lower in the observation group [6.66% (1/15) vs. 33.33% (5/15)] compared with the control group. All differences were statistically significant ( t = 3.50, 4.25, 7.49, 4.97, χ2 = 4.12, 5.12, all P < 0.05). Conclusions:For older adult patients with severe osteoporosis or irreparable proximal humeral comminuted fractures, artificial humeral head replacement yields more favorable outcomes compared with locking plate internal fixation, resulting in a better recovery of shoulder joint function.

Hearing loss is the most prevalent disabling disease. Cochlear implantation(CI) serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system(Favorable, Marginal, Poor). The consensus focuses on common hereditary non-syndromic hearing loss(such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1) and syndromic hereditary hearing loss(such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome), which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

The deficiency in immunogenicity and the presence of immunosuppression within the tumor microenvironment significantly hindered the efficacy of immunotherapy. Consequently, a nanoformulation containing metal sulfide of FeS and GSDMD plasmid (NPFeS/GD) had been developed to effectively augment antitumor immune responses through dual activation of immunogenic PANoptosis and ferroptosis, as well as reprogramming immunosuppressive effects via H2S amplification. The bioactive NPFeS/GD exhibited controlled release of GSDMD plasmid, H2S, and Fe2+ in response to the tumor microenvironment. Fe2+, H2S, and the expression of GSDMD protein could effectively elicit highly immunogenic PANoptosis and ferroptosis. Furthermore, releasing H2S could mitigate the overexpression of indoleamine 2,3-dioxygenase1 (IDO1) induced by immunogenic PANoptotic and ferroptotic cell death and disrupt the activity of IDO1. Consequently, NPFeS/GD effectively triggered the antitumor innate and adaptive immune responses through induction of PANoptotic and ferroptotic cell death and reshaped the tumor immunosuppressive microenvironment to enhance antitumor immunotherapy for metastasis inhibition. This study unveiled the significant potential of immunogenic PANoptosis and ferroptosis in H2S gas therapy for enhancing tumor immunotherapy, offering novel insights and ideas for the rational design of nanomedicine to enhance tumor immunogenicity while reprogramming the tumor immunosuppressive microenvironment.

OBJECTIVES:
To investigate the protective effects of graphene heating film far-infrared (FIR) hyperthermia therapy against frostbite in mice and its impacts on microcirculation and coagulation function.
METHODS:
Seventy-six C57BL/6J mice were randomized into control, model, graphene-FIR, and carbon fiber-FIR groups. After 7-day FIR intervention (4 h/day), the mice were subjected to acute (4 ℃, 4 h) and intermittent (4 ℃, 4 h/day for 3 days) cold exposure and the changes in rectal temperature were monitored. In liquid nitrogen frostbite experiment, 24 ICR mice were divided into model, graphene-FIR, and carbon fiber-FIR groups, and after a 7-day FIR pretreatment (4 h/day), the liquid nitrogen frostbite models were established and apparent scores of the wounds were assessed on days 3 and 6 after modeling. In carrageenan-induced thrombosis experiment, 40 ICR mice were allocated to control, model, graphene-FIR, carbon fiber-FIR, and prazosin groups to test the effect of a 7-day FIR intervention on thrombosis induced by intraperitoneal carrageenan injection (2.5 mg/kg) by measuring thrombus length, blood perfusion, and serum biomarkers (6-keto-PGF1α, TXB2, t-PA, IL-6, IL-1β, TNF‑α) 24 h after the injection.
RESULTS:
The mice in graphene-FIR group showed significantly elevated rectal temperature in cold exposure tests. In mice with liquid nitrogen-induced frostbite, graphene-FIR treatment significantly reduced the wound scores and reduced frostbite area, producing better effects than carbon fiber. In mice with carrageenan-induced thrombosis, graphene-FIR treatment significantly decreased tail thrombosis length and thrombosis area, increased blood perfusion, lowered serum levels of TXB2, TNF-α and IL-6, and increased the levels of 6-keto-PGF1α and t-PA.
CONCLUSIONS
Graphene heating film FIR therapy can alleviate frostbite injury in mice by improving microcirculation, suppressing thrombosis and inflammatory responses, and reducing coagulation dysfunction.
