ObjectiveTo investigate the value of different noninvasive diagnostic models in the diagnosis of esophageal and gastric varices since there is a high risk of esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension, and to provide a basis for the early diagnosis of esophageal and gastric varices. MethodsA total of 108 patients with significant portal hypertension due to compensated hepatitis B cirrhosis who attended Guangdong Provincial Hospital of Traditional Chinese Medicine from November 2017 to November 2023 were enrolled, and according to the presence or absence of esophageal and gastric varices under gastroscopy, they were divided into esophageal and gastric varices group (GOV group) and non-esophageal and gastric varices group (NGOV group). Related data were collected, including age, sex, imaging findings, and laboratory markers. The chi-square test was used for comparison of categorical data between groups; the least significant difference t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of five scoring models, i.e., fibrosis-4 (FIB-4), LOK index, LPRI, aspartate aminotransferase-to-platelet ratio index (APRI), and aspartate aminotransferase/alanine aminotransferase ratio (AAR). The binary logistic regression method was used to establish a combined model, and the area under the ROC curve (AUC) was compared between the combined model and each scoring model used alone. The Delong test was used to compare the AUC value between any two noninvasive diagnostic models. ResultsThere were 55 patients in the GOV group and 53 patients in the NGOV group. Compared with the NGOV group, the GOV group had a significantly higher age (52.64±1.44 years vs 47.96±1.68 years, t=0.453, P<0.05) and significantly lower levels of alanine aminotransferase [42.00 (24.00 — 17.00) U/L vs 82.00 (46.00 — 271.00) U/L, Z=-3.065, P<0.05], aspartate aminotransferase [44.00 (32.00 — 96.00) U/L vs 62.00 (42.50 — 154.50) U/L,Z=-2.351, P<0.05], and platelet count [100.00 (69.00 — 120.00)×109/L vs 119.00 (108.50 — 140.50)×109/L, Z=-3.667, P<0.05]. The ROC curve analysis showed that FIB-4, LOK index, LPRI, and AAR used alone had an accuracy of 0.667, 0.681, 0.730, and 0.639, respectively, in the diagnosis of esophageal and gastric varices (all P<0.05), and the positive diagnostic rates of GOV were 69.97%, 65.28%, 67.33%, and 58.86%, respectively, with no significant differences in AUC values (all P>0.05), while APRI used alone had no diagnostic value (P>0.05). A combined model (LAF) was established based on the binary logistic regression analysis and had an AUC of 0.805 and a positive diagnostic rate of GOV of 75.80%, with a significantly higher AUC than FIB-4, LOK index, LPRI, and AAR used alone (Z=-2.773,-2.479,-2.206, and-2.672, all P<0.05). ConclusionFIB-4, LOK index, LPRI, and AAR have a similar diagnostic value for esophageal and gastric varices in patients with compensated hepatitis B cirrhosis and significant portal hypertension, and APRI alone has no diagnostic value. The combined model LAF had the best diagnostic efficacy, which provides a certain reference for clinical promotion and application.

Objective To explore the mechanism by which zinc-regulated transporters, iron-regulated transporter-likeprotein 4 (ZIP4) regulates glycolysis and its impact on tumor progression in cholangiocarcinoma (CCA), providing a theoretical basis for targeted therapy of CCA. Methods ZIP4 expression in CCA was analyzed using the GEPIA database. Immuno-histochemistry (IHC) was used to detect ZIP4 expression in 20 paired CCA and adjacent non-tumor tissues. Stable ZIP4-overexpressing CCA cell lines (ZIP4-OE) were established. Gene set enrichment analysis was used to screen differentially expressed genes and pathways in ZIP-OE CCA cells. ZIP4, N-myc proto-oncogene protein (MYCN), and histone-lysine N-methyltransferase 2E (KMT2E) were knocked down using small interfering RNAs (siRNAs). The expression of glycolysis-related gene (glucose transporter 1 [Glut1], hexokinase 2 [HK2], and lactate dehydrogenase A [LDHA]) was measured by real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR). Glycolytic activity was assessed by measuring the extracellular acidification rate (ECAR). Cell proliferation was evaluated using colony formation assays, and cell migration was assessed using Transwell assays. A xenograft mouse model was constructed to examine CCA tumor growth. Protein levels of ZIP4, KMT2E, H3K4me3 (tri-methylation of lysine 4 on histone H3), and MYCN were detected by Western blotting. Results GEPIA database analysis and IHC results confirmed significantly higher ZIP4 expression levels in CCA tissues compared to adjacent non-tumor tissues (P<0.05). Compared to the control group, the ZIP4-OE group exhibited a significantly increased ECAR, along with significantly enhanced proliferation and migration abilities (P<0.01). Conversely, knockdown of ZIP4 suppressed CCA cells proliferation and migration. GEPIA analysis indicated that ZIP4 upregulates the transcription of oncogene MYCN, as well as glycolysis-related genes. Knockdown of MYCN abolished the ZIP4 overexpression-induced upregulation of Glut1, HK2, and LDHA gene transcription, reduced glycolysis, and significantly inhibited CCA cell proliferation and migration (P<0.05). Mechanistic studies demonstrated that ZIP4 increases H3K4me3 level via KMT2E, leading to MYCN transcription. Knockdown of KMT2E in CCA cells suppressed the ZIP4 overexpression-induced enhancement in H3K4me3 modification, resulting in MYCN downregulation and significantly reduced CCA cells proliferation and migration (P<0.05). Conclusions ZIP4 upregulates H3K4me3 modification through KMT2E, which recruits transcription factors to activate the transcription of MYCN. This subsequently enhances cellular glycolysis and promotes the proliferation and migration of CCA cells.

Objectives To understand the quality status of disinfection products in the market in Shaanxi Province, and to provide a basis for taking targeted management measures. Methods From 2020 to 2023, in accordance with the national disinfection product management regulations and standards, the physicochemical and microbial tests of disinfection products in Shaanxi Province were carried out through supervised sampling, and the test results were analyzed according to the active ingredients, illegal addition, stability, and bactericidal or bacteriostatic performance. Results The overall qualification rate of the active ingredient content of disinfectants sampled in Shaanxi Province was 90.48%, with the lowest qualification rate in 2023 (84.38%). The overall qualification rate of quantitative sterilization test of disinfectants was 90.12%, showing a decreasing trend year by year (P=0.272). The overall qualification rate of anti-bacterial products was 88.59%, and the bactericidal test results of 20 antibacterial products were all qualified. The overall qualification rate of bacteriostatic performance testing for bacteriostatic products was 86.17%, with the pass rate of bacteriostatic product germicidal efficacy testing of different components in descending order being quaternary ammonium salt/silver ion > guanidine > others > lysozyme, and there was statistically significant difference (P=0.004). The detection rate of illegal additives in antimicrobial products was 7.07%, with the main detection indicators being miconazole nitrate, clobetasol propionate, and dexamethasone acetate. Conclusion The qualified rate of disinfection products in Shaanxi Province is relatively high, but there is a downward trend. It is necessary to continue to strengthen the daily supervision and product testing of disinfection product manufacturers, and promote the continuous improvement of disinfection product quality.

Rapid and living guidelines are those developed in response to public health emergencies in a short period of time using a scientific and standardized approach. Subsequently, they provide timely and credible recommendations for decision makers through regular and frequent updates of clinical evidence and recommendations. In this paper, we introduced the definition of rapid and living guideline as well as analyzed the basic characteristics of eight rapid and living guidelines in the field of traditional Chinese medicine (TCM) published till 2023 June, summarizing three core methodological issues in relation to how to rapidly develop guidelines, how to formulate recommendations when there is lack of evidence, and how to ensure the timeliness of guidelines. Based on the analysis of current rapid and living guidelines, it is implicated that there is necessity to carry out rapid and living guideline in the field of TCM, and the methodology of rapid integration of multivariate evidence in the field of TCM needs to be further explored; furthermore, it is necessary to further explore the obstacles of implementation of guidelines and promote timely updating, all of which provide certain theoretical references for relevant guideline developers and researchers.

In developing rapid and living guidelines of traditional Chinese medicine (TCM) in response to public health emergencies, it is important that evidence continue to be reviewed, and clinical questions and recommendations updated if necessary, due to the rapid changes in disease progression and the continuous generation of relevant research evidence. This paper proposed that the updating scope in dynamic mode should first be identified; then evidence monitoring should be carried out in four aspects, including clinical research, related guidelines or laws and regulations, disease progression, as well as clinical use of recommendations and clinical needs; finally, based on the results of the evidence monitoring, different options should be made, including revising the clinical questions, updating the evidence and recommendations, and withdrawing the guideline.

Objective:To summarize the genotype and clinical phenotype of children with WWOX gene related developmental and epileptic encephalopathy (DEE).Methods:Case series studies. The clinical data of 12 children with WWOX gene related DEE who were admitted to the Neurological Department of Children′s Medical Center, Peking University First Hospital from June 2019 to December 2023 were analyzed. The children′s characteristics of gene variation, clinical phenotype, auxiliary examination results, treatment and prognosis were analyzed.Results:Among 12 children with WWOX gene related DEE, there were 7 boys and 5 girls, the age of seizure onset ranged from 10 days to 6 months (median 1.8 months). Multiple seizure types were observed, including focal seizures in 10 cases, epileptic spasms in 9 cases, tonic seizures in 4 cases, myoclonic seizures in 1 case. Among 12 cases, 9 cases had multiple seizure types. All 12 cases showed microcephaly and global developmental delay. Video electroencephalography showed slowed background activity in 6 cases, hyperarrhythmia in 6 cases, multifocal discharges in 6 cases, and focal discharges in 1 case. Epileptic spasms were detected in 8 cases, tonic seizures in 4 cases and myoclonic seizures in 1 case. Brain magnetic resonance imaging showed bilateral frontotemporal subarachnoid space widening in 5 cases, deep sulci in 3 cases, bilateral ventricular enlargement in 2 cases, callosal hypoplasia in 5 cases, and delayed white matter myelination in 3 cases. The phenotypes of 12 cases were consistent with the diagnosis of DEE, and 8 of them were diagnosed with infantile epileptic spasm syndrome. All the WWOX gene variants in 12 cases were complex heterozygous variants, including 20 variants, 11 variants and 1 large intragenic WWOX gene deletion (p.Ala149Thr, p.Arg156Ser, p.R167Tfs*8, p.Leu186Val, c.605+5G>A, p.Trp218*, p.His263Arg, p.Leu275fs*19*1, p.N285Kfs*10, p.Ser304Tyr, p.Met326Arg, loss1 exon2-8) had not been reported previously. The age of last follow-up ranged from 11 months to 5 years and 3 months. During the follow-up, 1 case died at the age of 1 year and 10 months, 2 cases were seizure-free, and 9 cases still had seizures after multiple anti-seizure medications.Conclusions:The seizure onset age of children with WWOX gene related DEE is usually less than 6 months, and some of them in neonate. The common seizure types include focal seizures and epileptic spasms. Children usually have microcephaly and global developmental delay. WWOX gene related DEE usually has drug refractory epilepsy.
