Objective: To enhance the recognition of necrotizing sialometaplasia (NS) by elucidating its clinical, pathological characteristics and key diagnostic points, providing a basis for the diagnosis and treatment of the disease. Methods: This study has been reviewed and approved by the Medical Ethics Committee, and informed consent has been obtained from patients. Review the data of a patient with NS occurring at the junction of the right soft and hard palate, and comprehensively analyze its diagnostic process based on its clinical manifestations, imaging, and histopathological examination results. And review the relevant literature on the disease. Results: This study describes a 24-year-old male patient with a documented betel nut habit (2 pieces/day for >6 months), who presented with a bone-deep, irregular crateriform ulcer (3 mm × 6 mm × 5 mm) localized to the right hard-soft palate junction. Spiral CT showed a local soft tissue defect with no apparent underlying bone destruction. Histopathology demonstrated chronic inflammation of the mucosal and minor salivary gland tissues, with no evidence of malignancy. A final diagnosis of NS was established. The ulcer healed completely three weeks after initiation of local anti-inflammatory therapy. A literature review indicates that NS is a rare, benign salivary gland disorder, typically occurring at the hard-soft palate junction in middle-aged men (40-60 years). Its etiology remains unclear, but it is widely attributed to salivary lobe infarction following mechanical trauma-induced ischemia. Due to its clinical resemblance to malignancy, it is often misdiagnosed. Treatment entails local anti-inflammatory measures and meticulous wound care aimed at promoting mucosal healing. Conclusion NS is a self-limiting, benign condition that poses a significant diagnostic challenge due to its close clinical simulation of malignancy. Thus, accurate diagnosis requires a combined assessment of clinical presentation, radiological features, and pathological findings. Treatment is predicated based on a conservative strategy with an emphasis on symptomatic management.

Acupuncture-moxibustion therapy has been known to ameliorate the symptoms of functional gastrointestinal disorders (FGIDs), although its mechanism remains unclear. The paper reviews the articles on acupuncture-moxibustion therapy for FGIDs in recent 5 years, and it is revealed that acupuncture-moxibustion therapy can alleviate FGIDs symptoms through regulating gastrointestinal motility, modulating visceral hypersensitivity, improving the impaired gastric-duodenal mucosal barrier and inflammation, balancing intestinal microbiota, and adjusting the gut-brain axis. Currently, the molecular mechanism of acupuncture-moxibustion therapy remains unknown for FGIDs, the specific disease target is not identified, and the interaction among various molecules is not elucidated adequately. The researches in the future should employ advanced technologies and methodologies to comprehensively and deeply explore and clarify the mechanism of acupuncture- moxibustion therapy for FGIDs.

The tumor microenvironment is a crucial factor in tumor occurrence and progression. The hypoxic microenvironment is widely present in tumor tissue and is a key endogenous factor accelerating tumor deterioration. The "blood stasis toxin" theory, as an emerging perspective in tumor research, is regarded as the unique "soil" in tumor progression from the perspective of traditional Chinese medicine(TCM) due to its dynamic evolution mechanism, which closely resembles the formation of the hypoxic microenvironment. Scientifically integrating TCM theories with the biological characteristics of tumors and exploring precise syndrome differentiation and treatment strategies are key to achieving comprehensive tumor prevention and control. This article focused on the hypoxic microenvironment of the tumor, elucidating its formation mechanisms and evolutionary processes and carefully analyzing the internal relationship between the "blood stasis toxin" theory and the hypoxic microenvironment. Additionally, it explored the interaction among blood stasis, toxic pathogens, and hypoxic environment and proposed micro-level prevention and treatment strategies targeting the hypoxic microenvironment based on the "blood stasis toxin" theory, aiming to provide TCM-based theoretical support and therapeutic approaches for precise regulation of the hypoxic microenvironment.

The traditional Chinese medicine(TCM) industry is a crucial part of China's pharmaceutical sector and plays a strategic role in ensuring public health and promoting economic and social development. In response to the practical demand for high-quality development of the TCM industry, this paper focused on the bottlenecks encountered during the digital and intelligent transformation of TCM production systems. Specifically, it explored technical strategies and methodologies for constructing the best TCM production mode. An innovative artificial intelligence(AI)-centered technical architecture for TCM production was proposed, focusing on key aspects of production management including process modeling, state evaluation, and decision optimization. Furthermore, a series of critical technologies were developed to realize the best TCM production mode. Finally, a novel AI-driven TCM production mode characterized by a closed-loop system of "measurement-modeling-decision-execution" was presented through engineering case studies. This study is expected to provide a technological pathway for developing new quality productive forces within the TCM industry.

Objective : To investigate the role of single nucleotide polymorphisms(SNP) of glutathione peroxidase 4(GPX4) gene in the risk of non-cardia gastric cancer. Methods: A total of 1 031 samples were selected, including 506 normal examiners and 525 patients with non-cardia gastric cancer.GPX4rs4807542, rs713041, rs2074451 and rs3746162 were genotyped by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). Unconditional Logistic regression was used to analyze the relationship between each SNP with the risk of non-cardia gastric cancer under the four genetic models. Results : The CT+TT genotype of rs713041 reduced the risk of non-cardia gastric cancer compared with the CC genotype(OR=0.699, 95%CI: 0.537-0.910). The GT+TT genotype of rs2074451 reduced the risk of non-cardia gastric cancer compared with the GG genotype(OR=0.681,95%CI: 0.520-0.893). The G-C-G-C haplotype, constructed by the four SNPs ofGPX4, was related to an increased risk of non-cardia gastric cancer(OR=1.262, 95%CI: 1.035-1.539), and G-T-T-C haplotype was related to a decreased risk of non-cardia gastric cancer(OR=0.784, 95%CI: 0.656-0.937). The fourth-order interaction ofGPX4rs4807542, rs713041, rs2074451 and rs3746162 played a synergistic effect in the risk of non-cardia gastric cancer(P<0.05). Conclusion GPX4rs713041 and rs2074451 are related to non-cardia gastric cancer susceptibility. The G-C-G-C haplotype composed ofGPX4rs4807542, rs713041, rs2074451 and rs3746162 is a risk factor for non-cardia gastric cancer, while the G-T-T-C haplotype is a protective factor. The interaction betweenGPX4rs4807542, rs713041, rs2074451 and rs3746162 is closely connected with the occurrence of non-cardia gastric cancer.

OBJECTIVE: To explore the clinical significance of circulating tumor DNA (ctDNA) in response evaluation and relapse monitoring for patients with primary mediastinal large B-cell lymphoma (PMBCL). METHODS: The clinical characteristics, efficacy and survival of 38 PMBCL patients in our hospital from January 2010 to April 2020 were retrospectively analyzed. The ctDNA monitoring was conducted by targeted next-generation sequencing (NGS). RESULTS: Among the 38 patients, 26 cases were female, and 32 cases were diagnosed with Ann Arbor stage I-II. The 5-year overall survival (OS) rate and progression-free survival (PFS) rate were 74.7% and 61.7%, respectively. Males and those with high aaIPI scores (3 points) had a relatively poor prognosis. The NGS results of 23 patients showed that STAT6 (65.2%), SOCS1 (56.5%), and TNFAIP3 (56.5%) were the most common mutated genes. Patients with stable disease (SD)/progressive disease (PD) exhibited enrichment in cell cycle, FoxO, and TNF signaling pathways. A total of 29 patients underwent end-of-treatment PET/CT (EOT PET/CT), and 16 of them received ctDNA monitoring with 12 negative. Among 6 patients with EOT PET/CT positive (Deauville 4), 4 underwent ctDNA monitoring, and 3 of them were negative, being still in continuous remission without any subsequent anti-tumor therapy. CONCLUSION CtDNA may be combined with PET/CT to assess efficacy, monitor relapse, and guide treatment of PMBCL.

BACKGROUND:Electrical stimulation is an effective treatment plan for peripheral nerve injuries,but different frequencies of electrical stimulation have different mechanisms and applications for promoting peripheral nerve recovery.OBJECTIVE:To systematically sort out and summarize the roles and applications of different frequencies of electrical stimulation in the treatment of peripheral nerve injuries,and to deeply analyze the advantages and disadvantages of various methods in order to find the most beneficial treatment strategy for patients'nerve recovery.METHODS:Computer-based searches were conducted in the China National Knowledge Infrastructure(CNKI)and PubMed databases from the inception of the databases to May 2024.The search terms included"peripheral nerve injury,electrical stimulation,low frequency electrical stimulation,medium frequency electrical stimulation,high frequency electrical stimulation,TENS,interfering electricity,short wave,ultrashort wave,frequency"in both English and Chinese.Ultimately,74 relevant documents were included for analysis.RESULTS AND CONCLUSION:Peripheral nerve injury,a common clinical disease,can cause sensory and motor dysfunction in patients.Low-frequency electrical stimulation can promote cell proliferation and accelerate the expression of nerve growth factor within the cell after electrical stimulation,promote macrophage recruitment and infiltration,accelerate the clearance of myelin debris,and promote myelin regeneration of damaged axons.Medium-frequency electrical stimulation can act on deeper tissues and is better for relieving neuropathic pain.High-frequency electrical stimulation can promote the proliferation of Schwann cells and macrophages,inhibit inflammatory factors,and rapidly recruit cells to the site of nerve injury,accelerating the speed of nerve repair.Different frequencies of electrical stimulation have their own advantages in promoting the recovery of peripheral nerve injuries,but there are still some issues,such as differences in the site of electrical stimulation and the treatment plans for various disease types.

To investigate the role of the DPP4-nestin axis in liver fibrosis induced by alveolar cyst infection,a murine model was established using C57BL/6 mice via hepatic portal vein injection.Liver histopathological changes were assessed using HE staining,while immunohistochemistry and immunofluorescence were employed to evaluate the expression levels of nestin and DPP4 in infected mouse livers.In vitro,J S1 cell line was stimulated with recombinant DPP4 protein to es-tablish a cellular model,and qPCR,Western blot,and shRNA lentivirus interference techniques were utilized to examine the involvement of the DPP4-nestin axis in hepatic stellate cell activation.The findings demonstrated that compared to the Sham group,liver tissue structure disruption and collagen deposition were evident along with significantly increased expressions of nestin and DPP4(P＜0.050 0),which colocalized with nesin and α-SMA.Furthermore,stimulation with recombi-nant DPP4 protein significantly enhanced JS1 cell activation(P＜0.050 0)as well as upregulated nestin expression(P＜0.050 0)when compared to control group cells.Notably,shRNA lentivirus-mediated inhibition of nestin expression effectively suppressed the activating effects exerted by re-combinant DPP4 protein on JS1 cells(P＜0.050 0).Collectively,these results highlight the crucial regulatory role played by the DPP4-nestin axis in hepatic stellate cell activation triggered by alveo-lar infection;thus,targeting this axis may represent a novel therapeutic strategy for treating alveo-lar infection-induced liver fibrosis.

Objective To analyze the clinical characteristics,drug sensitivity,and prognostic risk factors of patients with candidemia at our hospital,for providing evidence for rational drug use and improving prognosis.Methods A total of 181 patients with candidemia who were admitted to our hospital between January 2020 and December 2022 were selected for this study.Basic data,drug susceptibility test results,and clinical information were collected and analyzed.Patients were divided into two groups:a favorable prognosis group and a poor prognosis group;their prognostic risk factors were analyzed using univariate and binary logistic analyses.Results Candidemia was diagnosed from 181 Candida strains,including Candida parapsilosis(88 strains,48.62％),Candida albicans(34 strains,18.78％),Candida tropicalis(29 strains,16.02％),and Candida glabrata(17 strains,9.39％).Patients with candidemia were mainly diagnosed during general surgery(51.93％),intensive care unit(16.02％),and emergency department(9.94％).Univariate and binary logistic analyses showed that use of hormone and(or)immunosuppressive agents(OR=4.787),mechanical ventilation for more than 96 h(OR=4.558),renal insuffi-ciency(OR=4.426),and intrapulmonary infection(OR=4.228)were important independent risk factors.The highest detection rate of can-didemia in our hospital was for Candida parapsilosis.With the exception of Candida tropicalis,which was less sensitive to voriconazole,all other strains were sensitive to azole drugs.In conclusion,hormone and(or)immunosuppressive agents,mechanical ventilation for more than 96 h,renal insufficiency,and intrapulmonary infection are independent risk factors for poor prognosis in patients with candidemia.
