The Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines (hereinafter referred to as the Guidelines) is first specialized in the field of drug safety for oral Chinese patent medicines (OCPMs) in China. Rooted in China's healthcare context, the Guidelines address the unique usage patterns and risk characteristics of OCPMs, filling a regulatory gap in the pharmacovigilance framework specific to this category. To facilitate accurate understanding and effective implementation of the Guidelines, and to promote the standardized development of pharmacovigilance practices for OCPMs, this study offered a systematic interpretation based on its three core components. In the domain of risk monitoring and reporting, the paper analyzed the rationale for multi-source information integration and clarified the criteria for identifying key products and target populations for intensive monitoring. Regarding risk assessment, the Guidelines were examined from three dimensions of formulation components, medication behaviors, and population to address complex safety issues arising from medicinal constituents, irrational use, and individual susceptibility. In the area of risk control, the analysis focused on context-based interventions and dynamic closed-loop management strategies, exploring practical pathways to shift from passive response to proactive risk mitigation. Furthermore, this paper evaluated the applied value of the Guidelines and identified implementation challenges, such as insufficient capacity at the primary-care level and limited digital infrastructure. In response, the study proposed optimization strategies including establishing a dynamic updating mechanism, strengthening training at the grassroots level, and incorporating artificial intelligence to enhance pharmacovigilance capacity. This interpretation aims to provide actionable insights for marketing authorization holders (including manufacturers), pharmaceutical distributors, healthcare institutions, and research organizations, ultimately supporting the establishment and refinement of a full lifecycle pharmacovigilance system for OCPMs.

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.

ObjectiveTo analyze the epidemiological characteristics of latent tuberculosis infection (LTBI) among newly detained populations in eastern China, to identify high-risk groups, and to provide a scientific basis for formulating tuberculosis prevention and control strategies in the prison system. MethodsA cross-sectional study was conducted among the newly admitted detainees in two prisons in eastern China in 2022. Data on demographic characteristics, behavioral risk factors and previous disease history of the research subjects were collected through a structured questionnaire survey. The LTBI status of the detainees was determined using the QuantiFERON-TB Gold In-Tube (QFT-GIT) method. Lasso regression was used to screen variables, followed by multivariate logistic regression analysis to investigate the influencing factors of LTBI. ResultsA total of 305 detainees were included in the study. The median age of detainees was 35 (31, 43) years. The study population was predominantly male (67.21%), of Han ethnicity (95.41%), had a junior or senior high school education (59.34%), and was unemployed (31.80%). A history of smoking was reported by 52.79% of participants, while 57.70% reported no alcohol consumption. The majority had no history of hypertension (85.90%), diabetes mellitus (93.77%), human immunodeficiency virus (HIV) infection (97.38%), familial genetic diseases (95.08%), surgery or trauma (73.77%), drug use (92.79%), or hepatitis (93.77%). The LTBI rate was 14.75%. After comparing the demographic characteristics of LTBI and non-infected groups, it was found that smoking history (χ2=7.40, P=0.025), drug use history (χ2=5.49, P=0.019), and HIV infection (χ2=8.12, P=0.004) were statistically correlated with LTBI infection. The results of multivariate logistic regression analyses showed that smoking [adjusted odds ratio (aOR)=4.08, 95%CI: 1.60‒10.42, P=0.003], HIV infection (aOR=11.57, 95%CI: 2.50‒53.51, P=0.002) and drug use (aOR=3.04, 95%CI: 1.02‒9.09, P=0.046) were risk factors for LTBI. ConclusionThe LTBI rate among newly detainees in two prisons in eastern China is slightly lower than that among long-term detainees. Early screening and intervention should be implemented for newly detainees, with particular attention focused on high-risk groups such as those with a history of smoking, HIV infection, or drug use.

ObjectiveTo evaluate the clinical efficacy and safety of acupuncture in treating severe Bell's palsy and to explore its potential mechanism by investigating the effect on serum levels of glial cell line-derived neurotrophic factor (GDNF) and nerve growth factor (NGF). MethodsA randomized, subject-blinded, sham-acupuncture controlled trial was conducted. A total of 130 patients with severe Bell's palsy were randomly allocated into a treatment group or a control group at a 1∶1 ratio. Both groups received conventional western medicine. In addition, the treatment group received acupuncture, while the control group received sham acupuncture, with each session lasting 30 minutes. The treatment course lasted 8 weeks for both groups, followed by a follow-up assessment at week 12. The primary outcome was the proportion of patients achieving House-Brackmann (H-B) grade Ⅱ or lower at week 8. Secondary outcomes included Sunnybrook facial grading system scores at week 0, 4, 8, and 12, the time to satisfactory recovery(the time required to achieve H-B grade≤Ⅱ), distribution of H-B grades and facial disability index (FDI) scores including the physical function subscale (FDIP) and social/well-being function subscale (FDIS) scores at week 0, 4, 8, and 12, and serum GDNF and NGF levels at week 0, 4, and 8. Adverse events and participants' self-assessments of treatment efficacy were also recorded. ResultsA total of 122 participants completed the study, including 62 in the treatment group and 60 in the control group. An intention-to-treat (ITT) analysis was performed, and missing data were handled using the last observation carried forward (LOCF) method. The proportion of patients achieving H-B grade ≤grade Ⅱ at week 8 was 78.5% (51/65) in the treatment group, significantly higher than 49.2% (32/65) in the control group (P<0.05). The Sunnybrook scores, FDIP and FDIS scores increased, while H-B grades decreased at week 4, 8, and 12 in both groups compared to week 0; moreover, improvements in all outcome measures were significantly greater in the treatment group than in the control group (P<0.05). The median time to satisfactory recovery was 6 weeks (95%CI: 5.697-6.303) in the treatment group, significantly shorter than 12 weeks (95%CI: 8.314-15.686) in the control group (P<0.05). Serum levels of GDNF and NGF were significantly higher in the treatment group at weeks 4 and 8 (P<0.05). No serious acupuncture-related adverse events occurred in either group. Adverse events were reported in 5 patients (7.69%) in the treatment group and 4 patients (6.15%) in the control group, with no statistically significant difference between groups (P>0.05). Patients' self-assessment of treatment efficacy after 8 weeks treatment was significantly better in the treatment group (P<0.05). ConclusionAcupuncture can effectively improve facial nerve function and shorten recovery time in patients with severe Bell's palsy, with a favorable safety profile. The therapeutic mechanism may be associated with the upregulation of serum GDNF and NGF levels.

Tumor drug resistance is an important problem in the failure of chemotherapy and targeted drug therapy, which is a complex process involving chromatin remodeling. SWI/SNF is one of the most studied ATP-dependent chromatin remodeling complexes in tumorigenesis, which plays an important role in the coordination of chromatin structural stability, gene expression, and post-translation modification. However, its mechanism in tumor drug resistance has not been systematically combed. SWI/SNF can be divided into 3 types according to its subunit composition: BAF, PBAF, and ncBAF. These 3 subtypes all contain two mutually exclusive ATPase catalytic subunits (SMARCA2 or SMARCA4), core subunits (SMARCC1 and SMARCD1), and regulatory subunits (ARID1A, PBRM1, and ACTB, etc.), which can control gene expression by regulating chromatin structure. The change of SWI/SNF complex subunits is one of the important factors of tumor drug resistance and progress. SMARCA4 and ARID1A are the most widely studied subunits in tumor drug resistance. Low expression of SMARCA4 can lead to the deletion of the transcription inhibitor of the BCL2L1 gene in mantle cell lymphoma, which will result in transcription up-regulation and significant resistance to the combination therapy of ibrutinib and venetoclax. Low expression of SMARCA4 and high expression of SMARCA2 can activate the FGFR1-pERK1/2 signaling pathway in ovarian high-grade serous carcinoma cells, which induces the overexpression of anti-apoptosis gene BCL2 and results in carboplatin resistance. SMARCA4 deletion can up-regulate epithelial-mesenchymal transition (EMT) by activating YAP1 gene expression in triple-negative breast cancer. It can also reduce the expression of Ca2+ channel IP3R3 in ovarian and lung cancer, resulting in the transfer of Ca2+ needed to induce apoptosis from endoplasmic reticulum to mitochondria damage. Thus, these two tumors are resistant to cisplatin. It has been found that verteporfin can overcome the drug resistance induced by SMARCA4 deletion. However, this inhibitor has not been applied in clinical practice. Therefore, it is a promising research direction to develop SWI/SNF ATPase targeted drugs with high oral bioavailability to treat patients with tumor resistance induced by low expression or deletion of SMARCA4. ARID1A deletion can activate the expression of ANXA1 protein in HER2+ breast cancer cells or down-regulate the expression of progesterone receptor B protein in endometrial cancer cells. The drug resistance of these two tumor cells to trastuzumab or progesterone is induced by activating AKT pathway. ARID1A deletion in ovarian cancer can increase the expression of MRP2 protein and make it resistant to carboplatin and paclitaxel. ARID1A deletion also can up-regulate the phosphorylation levels of EGFR, ErbB2, and RAF1 oncogene proteins.The ErbB and VEGF pathway are activated and EMT is increased. As a result, lung adenocarcinoma is resistant to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). Although great progress has been made in the research on the mechanism of SWI/SNF complex inducing tumor drug resistance, most of the research is still at the protein level. It is necessary to comprehensively and deeply explore the detailed mechanism of drug resistance from gene, transcription, protein, and metabolite levels by using multi-omics techniques, which can provide sufficient theoretical basis for the diagnosis and treatment of poor tumor prognosis caused by mutation or abnormal expression of SWI/SNF subunits in clinical practice.

OBJECTIVE:
To identify prognostic genes associated with lysosome-dependent cell death (LDCD) in patients with gastric cancer (GC).
METHODS:
Differentially expressed genes (DEGs) were identified using The Cancer Genome Atlas - Stomach Adenocarcinoma. Weighted gene co-expression network analysis was performed to identify the key module genes associated with LDCD score. Candidate genes were identified by DEGs and key module genes. Univariate Cox regression analysis, and least absolute shrinkage and selection operator regression and multivariate Cox regression analyses were performed for the selection of prognostic genes, and risk module was established. Subsequently, key cells were identified in the single-cell dataset (GSE183904), and prognostic gene expression was analyzed. Cell proliferation and migration were assessed using the Cell Counting Kit-8 assay and the wound healing assay.
RESULTS:
A total of 4,465 DEGs, 95 candidate genes, and 4 prognostic genes, including C19orf59, BATF2, TNFAIP2, and TNFSF18, were identified in the analysis. Receiver operating characteristic curves indicated the excellent predictive power of the risk model. Three key cell types (B cells, chief cells, and endothelial/pericyte cells) were identified in the GSE183904 dataset. C19orf59 and TNFAIP2 exhibited predominant expression in macrophage species, whereas TNFAIP2 evolved over time in endothelial/pericyte cells and chief cells. Functional experiments confirmed that interfering with C19orf59 inhibited proliferation and migration in GC cells.
CONCLUSION
C19orf59, BATF2, TNFAIP2, and TNFSF18 are prognostic genes associated with LDCD in GC. Furthermore, the risk model established in this study showed robust predictive power.

The culture of suspended Vero cells is facing difficulties such as low cell viability and long doubling time. To investigate the main reasons for the slow growth and low viability of suspended Vero cells, this study conducted transcriptomic analysis of suspended Vero cells (Vero-XF) and adherent Vero cells (Vero-AD) to screen the differentially expressed genes (DEGs) affecting the growth of suspended cells. In addition, epidermal growth factor (EGF) was supplemented to the culture system to improve the growth of Vero-XF. The results showed that compared with the Vero-AD group, the Vero-XF group had 7 376 significant DEGs. Kyoto encyclopedia of genes and genomes enrichment analysis revealed that the DEGs were mainly enriched in the autophagy and mitophagy pathways. Eleven DEGs were selected and verified by quantitative real-time PCR, which showed up-regulated expression of ATG9B, WIPI2, LAMP2, OPTN, Rab7a, and DEPTOR and down-regulated expression of ATG4D, being consistent with the results of transcriptomic analysis. In addition, the Vero-XF group showed significantly up-regulated expression of ATG101, ATG2A, and STX17 and insignificant change in the expression of NBR1, compared with the Vero-AD group. The protein levels of LC3 and P62 in Vero-XF and Vero-AD were determined by Western blotting, which showed up-regulated expression of LC3Ⅱ/Ⅰ and down-regulated expression of P62 in Vero-XF, indicating a higher level of autophagy. Finally, the exogenous supplementation of EGF at 10, 20, and 30 μg/L in the culture system reduced the autophagy level of Vero-XF by 22.35%, 48.15%, and 71.29%, increased the specific growth rate by 15.48%, 33.33%, and 57.14%, and decreased the apoptosis rate by 2.84%, 15.46%, and 16.23%, respectively. The results of this study preliminarily reveal that the activation of autophagy is one of the reasons for the slow growth of Vero-XF, which provides reference for the subsequent culture of suspended Vero cells.

Objective:To evaluate the effect of superficial temporal artery to middle cerebral artery (STA-MCA) bypass on cognitive function, cerebral perfusion, and integrity of white matter tracts by comparing cognitive function scores, fractional anisotropy (FA), time to maximum (T max), and cerebral blood flow (CBF) at different time points before and after STA-MCA bypass, and analyze the relations of cognitive function with cerebral perfusion and white matter tract integrity so as to provide evidences for treatment of moyamoya disease (MMD) patients with mild cognitive impairment. Methods:A retrospective analysis was performed; 30 MMD patients with mild cognitive impairment received STA-MCA bypass at Department of Neurosurgery, Lianyungang Hospital Affiliated to Xuzhou Medical University (Lianyungang First People's Hospital) from January 2023 to August 2024 were enrolled. Before and 1, 3, and 6 months after STA-MCA bypass, all patients accepted Montreal cognitive assessment (MoCA), CT perfusion imaging, and diffusion tensor imaging (DTI). Differences in MoCA score, CBF, T max, and FA at different time points before and after surgery were compared. Spearman rank correlation was used to analyze the correlation of MoCA score with cerebral perfusion parameters and FA. Results:(1) In these MMD patients with mild cognitive impairment, CBF 3 and 6 months after STA-MCA bypass was significantly increased compared with that before STA-MCA bypass, and CBF 6 months after STA-MCA bypass was significantly higher than that 1 and 3 months after STA-MCA bypass ( P<0.05); T max 1, 3 and 6 months after STA-MCA bypass was significantly shortened compared with that before STA-MCA bypass, and T max 6 months after STA-MCA bypass was significantly shortened than that 1 and 3 months after STA-MCA bypass ( P<0.05); FA 6 months after STA-MCA bypass was significantly increased compared with that before, and 1 and 3 months after STA-MCA bypass ( P<0.05); MoCA score 6 months after STA-MCA bypass was significantly increased compared with that before and 1 month after STA-MCA bypass ( P<0.05). (2) In MMD patients with mild cognitive impairment, the preoperative MoCA score was positively correlated with preoperative CBF and FA ( r s=0.428, P=0.018; r s=0.438, P=0.015) and negatively correlated with preoperative T max ( r s=-0.380, P=0.039); 6 months after STA-MCA bypass, the MoCA score was positively correlated with CBF and FA ( r s=0.365, P=0.047; r s=0.400, P=0.028) and negatively correlated with T max ( r s=-0.371, P=0.043). Conclusion:STA-MCA bypass can improve cerebral perfusion, white matter fiber tract repair and cognitive function in MMD patients with mild cognitive impairment, and improvement of cognitive function is related to cerebral perfusion and white matter fiber tract repair.
