Since the founding of the People’s Republic of China, remarkable achievements have been gained in infectious disease prevention and control, and rich practical experiences have been accumulated. If these experiences are shared with developing countries, it will greatly contribute to global infectious disease control and global health security. Under the framework of Forum on China-Africa Cooperation, a series of China-Africa public health capacity training programs have been recently held in China, in order to help improve the capability of infectious disease control in African countries. This article summarized and refined good design concepts and practices from these programs, so as to provide insights into sustainable optimization of China-Africa public health capacity training and improvements of the training effectiveness.

AIM: To investigate the predictive value of serum histone deacetylase 1(HDAC1)and endothelial nitric oxide synthase(eNOS)for infectious endophthalmitis after cataract surgery.METHODS: A total of 362 cataract patients(362 eyes)admitted to our hospital from January 2020 to January 2023 were selected as the research objects. According to the occurrence of postoperative infectious endophthalmitis, they were divided into infection group(15 cases, 15 eyes)and non-infection group(347 cases, 347 eyes). Enzyme linked immunosorbent assay(ELISA)was applied to detect the levels of serum HDAC1 and eNOS in all subjects, and the levels of serum HDAC1 and eNOS in both groups were compared; the influencing factors of infectious endophthalmitis were analyzed by multivariate Logistic regression; the receiver operative curve(ROC)was applied to analyze the predictive value of serum HDAC1 and eNOS levels for postoperative infectious endophthalmitis in cataract patients.RESULTS: The levels of serum HDAC1 and eNOS in the infected group were obviously higher than those in the uninfected group(all P<0.01). Surgical time, vitreous overflow, HDAC1, and eNOS were all risk factors for postoperative infectious endophthalmitis(all P<0.05). ROC results showed that the AUC of HDAC1 and eNOS in predicting postoperative infectious endophthalmitis in cataract patients was 0.878 and 0.877, respectively, with sensitivity of 88.7% and 87.7%, specificity of 70.4% and 7.8%, respectively, while the AUC of the two combination in predicting postoperative infectious endophthalmitis in cataract patients was 0.978, with a sensitivity of 86.7% and a specificity of 85.3%.CONCLUSION:The serum levels of HDAC1 and eNOS in patients with infectious endophthalmitis after cataract surgery are obviously increased, and the combined detection of serum HDAC1 and eNOS can improve the predictive efficacy of infectious endophthalmitis in cataract patients after surgery. Both can provide reference for clinical diagnosis and treatment.

Objective:To compare the clinical characteristics of patients with drug-induced liver injury (DILI) caused by Polygonum multiflorum and other drug-induced liver injuries (DILI).Methods:A retrospective cohort study was conducted. Clinical data of seventy-three cases confirmedly diagnosed with DILI caused by Polygonum multiflorum, 168 cases diagnosed with DILI caused by other traditional Chinese medicines, and 225 cases diagnosed with DILI caused by modern medicines admitted to Peking University First Hospital, the Fipth People's Hospital of Wuxi, Yantai Qishan Hospital, and Qinhuangdao Third Hospital from January 1995 to August 2019 were selected and collected as the research subjects. The Mann-Whitney U test was used for comparison of skewed distribution of continuous data between two groups. The Kruskal-Wallis rank-sum test was used for comparison between three groups. The χ2 test was used for comparing count data between groups. Results:Among the 73 cases with DILI caused by Polygonum multiflorum, 11 (15.1%) took a single herb of Polygonum multiflorum (including its powder and boiled water), 37 (50.7%) took traditional Chinese patent medicines containing Polygonum multiflorum, and 25 (34.2%) took a traditional Chinese medicine formula containing Polygonum multiflorum. The age of the DILI group caused by Polygonum multiflorum was 48 years old, which was lower than the other two groups (the DILI group caused by other traditional Chinese medicines: 55 years old, the DILI group caused by modern medicines: 52 years old; P<0.01). The levels of alanine aminotransferase (ALT), aspartate aminotransferase, and alkaline phosphatase were all higher than the other two groups ( P<0.05). The proportion of patients with antinuclear antibody positivity rate and severity of liver damage grade 3 was higher in the DILI group induced by Polygonum multiflorum than those in the modern drug-induced DILI group ( P<0.05). The liver cell injury type accounted for 96.6% (57/59) in the DILI group caused by Polygonum multiflorum, which was higher than that in the modern drug-induced DILI group (69.3%, 156/225) ( P<0.001). There was no statistically significant difference ( P>0.05) in gender, age, medication duration, and various biochemical indicators between patients with DILI caused by Polygonum multiflorum monotherapy and compound preparations in terms of compatibility. The ALT level in the DILI group caused by raw Polygonum multiflorum was higher than that in the DILI group caused by processed Polygonum multiflorum [the DILI group caused by raw Polygonum multiflorum: 1 289.0(921.8, 1 851.8)U/L, the DILI group caused by processed Polygonum multiflorum: 890.0(304.0,1 320.0)U/L; P<0.05] according to the comparison of processing methods. Conclusion:The degree of DILI caused by Polygonum multiflorum is more obvious than that caused by other drugs. There was no difference in the degree of DILI caused by the single and the compound formulation. However, the liver damage caused by raw Polygonum multiflorum was more severe than that caused by processed Polygonum multiflorum.

Objective To investigate the current status of adverse drug reaction(ADR)monitoring in medical institu-tions under China's pharmacovigilance framework in Guangdong Province,and to propose evidence-based strategies for enhancing institutional monitoring capabilities.Methods A cross-sectional survey was conducted using a structured questionnaire devel-oped in alignment with national regulatory requirements and expert consensus.Data were collected from 65 medical institutions,including general hospitals,traditional Chinese medicine hospitals,and maternal/children's hospitals,across 21 prefecture-level cities in Guangdong.Descriptive and comparative analyses were performed to evaluate institutional practices.Results All 65 in-stitutions submitted valid responses.Among them,63(96.9％)had established standardized ADR reporting protocols,with 93.8％(61/65)delegating oversight to pharmacy departments.ADR data were predominantly collected via institutional informa-tion systems(67.7％,44/65),though these systems focused on passive reporting and basic data aggregation,lacking functional-ities for active signal detection or risk alert mechanisms.Significant disparities(P＜0.05)were observed across hospitals of dif-ferent tiers in reporting modalities,system sophistication,analytical frequency,and early warning implementation.Notably,mo-nitoring practices for conditionally approved drugs(e.g.,emergency-authorized therapeutics)exhibited systemic deficiencies.Conclusions To address these gaps,the following measures are recommended:Accelerating the adoption of intelligent monito-ring systems to enable real-time ADR detection and predictive analytics;Implementing tiered resource allocation policies to ensure equitable capability development;Establishing specialized protocols for high-risk pharmaceuticals,particularly conditionally ap-proved and fast-tracked drugs;Strengthening interdisciplinary training programs to improve pharmacovigilance literacy among healthcare practitioners.These interventions aim to foster a proactive risk management culture and advance patient safety within China's evolving healthcare landscape.

Objective To explore the expression level of zinc finger CCCH-type containing 13 (ZC3H13)in gastric cancer based on bioinformatics techniques,along with clinicopathological stag-ing,prognostic survival,immune infiltration,correlation analysis,protein-protein interactions,and enrichment analysis.Methods Using the UALCAN database and the Gene Expression Profiling Inter-active Analysis(GEPIA)databases,the expression differences of ZC3H13 between normal gastric tis-sues and gastric cancer tissues,as well as the significance of clinical pathological data were compared.The correlation between ZC3H13 expression levels in gastric cancer tissues and patient survival progno-sis was assessed using univariate survival analysis through the Kaplan-Meier Plotter website and the GEPIA database.The relationship between ZC3H13 expression and immune infiltration levels in gastric cancer was explored using the Tumor Immune Estimation Resource(TIMER)database.Co-expression genes significantly correlated with ZC3H13 expression in gastric cancer were identified through the Linkedomics database.The protein-protein interaction network of ZC3H13 and its common target genes in gastric cancer was constructed using the STRING website,followed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses.Results Compared to normal gastric tissues,ZC3H13 was significantly upregulated in gastric cancer,and its high ex-pression was closely associated with patient age,ethnicity,tissue subtype,and other factors.Pa-tients with high ZC3H13 expression showed no statistically significant difference in overall survival(OS)or progression-free survival(PFS)time compared to patients with low expression(P＞0.05).Immune analysis revealed a significant negative correlation between ZC3H13 expression and the infiltration density of CD8+T cells,macrophages,neutrophils,and dendritic immune cells in gastric cancer(P＜0.05).Correlation analysis showed that ZC3H13 expression in gastric cancer was significantly positively correlated with the gene expression of DAK,DDK1,and BCL7C,and negatively correlated with the expression of FAM10A4,SLC6A7,and TAC1(P＜0.05).The pro-tein interaction network indicated that proteins interacting with ZC3H13 in gastric cancer included VIRMA,WTAP,METTL3,METTL14,RBM15,and others.Enrichment analysis revealed that dif-ferentially expressed genes in gastric cancer were mainly enriched in RNA polymerase,nucleotide excision repair,thyroid hormone signaling pathway,and other pathways.Conclusion ZC3H13 is overexpressed in gastric cancer,and its elevated expression is linked to the clinicopathological stage,patient survival time,and immune cell infiltration levels.Additionally,ZC3H13 may partici-pate in the initiation and progression of gastric cancer through interactions with key molecules such as VIRMA and METTL3.These findings suggest that ZC3H13 could serve as a potential biomarker and therapeutic target for gastric cancer prognosis.

AIM: To investigate the expression changes and significance of serum microRNA-34a-5p(miR-34a-5p)and silent information regulator T1(SIRT1)in patients with endophthalmitis after cataract surgery.METHODS: Patients with endophthalmitis after cataract surgery from May 2020 to May 2024 were selected as infection group(20 cases), and patients without endophthalmitis were selected as control group(74 cases). Serum SIRT1 levels were detected by ELISA; the serum level of serum miR-34a-5p was detected by qRT-PCR; the correlation between miR-34a-5p and SIRT1 was analyzed by Pearson method; Logistic regression was used to analyze the influencing factors of endophthalmitis after cataract operation. Receiver operating characteristic(ROC)curve was drawn to analyze the diagnostic value of serum miR-34a-5p and SIRT1 levels in postoperative endophthalmitis.RESULTS: Compared with the control group, the serum level of miR-34a-5p in the infected group was significantly increased(P<0.001), and the serum level of SIRT1 was significantly decreased(P<0.001). Correlation analysis showed that miR-34a-5p was negatively correlated with SIRT1(r=-0.421, P<0.001). Logistic multivariate regression analysis showed that miR-34a-5p was an independent risk factor affecting endophthalmitis infection after cataract surgery(OR=3.532, P<0.05), and SIRT1 was a protective factor affecting endophthalmitis infection after cataract surgery(OR=0.875, P<0.05). The ROC curve showed that the area under curve(AUC)of serum miR-34a-5p combined with SIRT1 in the diagnosis of postoperative endophthalmitis was 0.933(95%CI: 0.861-0.975).CONCLUSION:Serum levels of miR-34a-5p are highly expressed and SIRT1 is lowly expressed in postoperative endophthalmitis, they are closely related to the occurrence and development of endophthalmitis after cataract surgery.

AIM: To explore the value of changes in the serum expression levels of triggering receptor expressed on myeloid cells-1(TREM-1)and matrix metalloproteinase-9(MMP-9)in early clinical diagnosis of postoperative endophthalmitis in patients with cataract surgery.METHODS: A total of 21 patients who underwent cataract surgery with infectious endophthalmitis in our hospital from May 2021 to May 2023 were selected as the study subjects(endophthalmitis group), and another 100 patients who underwent cataract surgery without endophthalmitis were selected as the non-endophthalmitis group. The serum levels of TREM-1, MMP-9, and the expression levels of inflammatory factors such as interleukin-1β(IL-1β), IL-17, and tumor necrosis factors-α(TNF-α)were detected and compared between the endophthalmitis group and the non-endophthalmitis group. The correlation between TREM-1 and MMP-9 was analyzed by Pearson method. Logistic regression was applied to analyze the factors that affected the occurrence of endophthalmitis in cataract patients after surgery. Receiver operating characteristic(ROC)curve was applied to analyze the early clinical diagnostic efficacy of TREM-1 and MMP-9 levels for postoperative endophthalmitis in cataract patients.RESULTS: Compared with the non-endophthalmitis group after cataract surgery, the expression levels of serum TREM-1, MMP-9, and inflammatory factors IL-1β, IL-17, and TNF-α in the endophthalmitis group were obviously increased(all P<0.05), and the TREM-1 was positively correlated with MMP-9(r=0.389, P<0.001). Logistic regression results showed that elevated levels of serum TREM-1 and MMP-9 expression, and vitreous overflow were independent risk factors for postoperative endophthalmitis in cataract patients(all P<0.05). ROC curve showed that the area under the curve(AUC)of TREM-1, MMP-9, and their combination in diagnosing postoperative endophthalmitis in cataract patients was 0.845, 0.844, and 0.935, respectively, and the clinical efficacy of the combination of the two in early diagnosis of postoperative endophthalmitis in cataract patients was better than that of serum TREM-1 and MMP-9 alone(all P<0.05).CONCLUSION: The expression levels of serum TREM-1 and MMP-9 in patients with endophthalmitis after cataract surgery are abnormally elevated, and the combination of the two has high clinical application value in early diagnosis of endophthalmitis after cataract surgery.

Non-small cell lung cancer (NSCLC), a leading cause of cancer-related deaths worldwide, remains a significant clinical challenge despite advances in immune checkpoint inhibitors therapy, with drug resistance persisting as a major obstacle. Palmitoylation, a critical post-translational modification (PTM) primarily catalyzed by palmitoyltransferases of the zinc finger DHHC-type (ZDHHC), has recently demonstrated important implications in NSCLC. This review aims to elucidate the mechanisms and clinical potential of ZDHHC-mediated protein palmitoylation in NSCLC progression and immune escape.
