Traditional Chinese medicine （TCM） is widely used in the clinical management of chronic hepatitis B in China and has exhibited certain advantages in alleviating symptoms， regulating overall physiological status， and assisting in the intervention against disease progression. However， there is still a lack of a comprehensive clinical efficacy evaluation system for TCM treatment of chronic hepatitis B， with inconsistencies in the selection of evaluation indicators and limited objectivity and standardization in the assessment of syndromes and symptoms， which have limited the systematic accumulation of evidence regarding TCM efficacy and the incorporation of TCM into clinical guidelines and expert consensus statements. This article systematically reviews the current status of research on the clinical efficacy evaluation of TCM for chronic hepatitis B and analyzes the achievements made in the field of TCM therapy and integrated traditional Chinese and Western medicine therapy for chronic liver diseases in China’s national major infectious disease research programs during the periods of the Eleventh to Thirteenth Five-Year Plans. It also points out related issues that remain to be addressed and proposes a conceptual framework and specific components for constructing a TCM clinical efficacy evaluation system from the perspectives of evaluation objectives， indicator composition， and application scenarios， in order to provide a reference for the development of related standards， clinical research， and the standardization of integrated traditional Chinese and Western medicine diagnosis and treatment.

The p60 subunit of the chromatin assembly factor-1 complex, that is, chromatin assembly factor-1 subunit B (CHAF1B), is a histone H3/H4 chaperone crucial for the transcriptional regulation of cell differentiation and self-renewal. CHAF1B is overexpressed in several cancers and may represent a potential target for cancer therapy. However, its expression and clinical significance in lung squamous-cell carcinoma (LUSC) remain unclear. In this study, we performed weighted gene correlation network analysis to analyze the Gene Expression Omnibus GSE68793 LUSC dataset and identified CHAF1B as one of the most important driver gene candidates. Immunohistochemical analysis of 126 LUSC tumor samples and 80 adjacent normal lung tissues showed the marked upregulation of CHAF1B in tumor tissues and the negative association of its expression level with patient survival outcomes. Silencing of CHAF1B suppressed LUSC proliferation in vitro and LUSC tumor growth in vivo. Furthermore, bulk RNA sequencing of CHAF1B knockdown cells indicated SET domain containing 7 (SETD7) as a significant CHAF1B target gene. In addition, CHAF1B competitively binds to the SETD7 promoter region and represses its transcription. Altogether, these results imply that CHAF1B plays a vital role in LUSC tumorigenesis and may represent a potential molecular target for this deadly disease.

Objective:To explore the clinical features, genetic traits and prognosis status of acute myeloid leukemia (AML) patients with TP53 mutation.Methods:A retrospective case series study was performed. Clinical data of 42 AML patients with TP53 mutation abundance of at least 10% who were admitted to the First Hospital of Jilin University from April 2018 to August 2023 were collected. Chromosomal karyotypes were detected using fluorescence in situ hybridization (FISH), and next-generation sequencing (NGS) was performed on bone marrow samples from these patients. The Kaplan-Meier method was utilized to analyze the recurrence-free survival (RFS) of 22 patients who achieved complete remission (CR) after induction therapy, as well as the overall survival (OS) of 39 patients who underwent treatment. The Cox proportional hazards model was employed to analyze the factors influencing RFS and OS. Thirty-one patients who underwent induction therapy for ≥ 2 courses were divided into the non-refractory group (22 cases) and the refractory group (9 cases) based on whether CR was achieved after induction therapy, and the clinical and genetic characteristics and prognosis of the two groups were compared.Results:Among the 42 AML patients with TP53 mutation, there were 26 males and 16 females, with a median age [ M( Q1, Q3)] of 57.0 (44.0, 63.5) years. At the initial stage, the median white blood cell count in peripheral blood was 4.06×10 9/L (2.59×10 9/L, 27.36×10 9/L), the median proportion of bone marrow primitive cells was 45.25% (29.00%, 80.63%), the proportion of primitive and immature cells in bone marrow cell immune analysis was 28.70% (12.71%, 61.48%), and the median TP53 mutation abundance was 55.48% (38.72%, 73.31%). Among the 42 patients, 23 cases (54.76%) had complex chromosomal karyotypes, with the most frequent abnormal chromosomes being chromosome 5 (47.62%, 20 cases), chromosome 7 (45.24%, 19 cases) and chromosome 17 (26.19%, 10 cases). The mutant genes with high mutation frequency were DNMT3A (19.05%, 8 cases), N/KRAS (19.05%, 8 cases), ASXL1 (16.67%, 7 cases) and NPM1 (16.67%, 7 cases). Among the 39 patients with detailed TP53 mutation data, 36 had missense mutations and 3 had frameshift mutations. In the non-refractory and refractory groups, the N/KRAS mutation rates were 13.6% (3/22) and 55.6% (5/9), respectively ( P = 0.027). The median RFS time of 22 CR patients after induction therapy was 109 d (95% CI: 57-483 d). The results of multivariate Cox regression analysis showed that complex chromosomal karyotype was an independent risk factor for RFS ( HR = 11.819, 95% CI: 1.345-103.880, P = 0.028). The median RFS time of patients without and with complex chromosomal karyotypes was 842 d (95% CI: 0-1 716 d) and 148 d (95% CI: 88-208 d), respectively, and the difference in RFS between the two groups was statistically significant ( P = 0.001). The median OS time of 39 patients receiving treatment was 151 d (95% CI: 75-227 d). The results of multivariate Cox regression analysis showed that NPM1 gene mutation was an independent protective factor for OS ( HR = 0.289, 95% CI: 0.075-1.114, P = 0.071). The median OS time of patients with and without NPM1 gene mutation was 1 562 d (95% CI: 610- 1 710 d) and 136 d (95% CI: 99-173 d), respectively, and the difference in OS between the two groups was statistically significant ( P = 0.020). Conclusions:TP53-mutant AML patients often have poor chromosomal karyotypes and genetic abnormalities, while refractory AML patients often have N/KRAS mutation. The complex chromosomal karyotype is a risk factor for RFS, while NPM1 gene mutation is a protective factor for OS.

OBJECTIVE: To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI. METHODS: From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients. RESULTS: Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation. CONCLUSION Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

AIM:To investigate the antitumor activity and targets of baicalein(Bai)in pancreatic cancer using network pharmacology combined with in vitro and in vivo experiments.METHODS:The targets of Bai and pancreatic can-cer were analyzed via multi-data screening.A protein-protein interaction network was constructed using STRING,and core targets were identified via Cytoscape.Functional enrichment was analyzed by Gene Ontology(GO)and Kyoto Ency-clopedia of Genes and Genomes(KEGG).Antitumor effects of Bai were assessed in pancreatic cancer cells Aspc-1 and Bxpc-3 using MTT and colony formation assays for proliferation,flow cytometry for apoptosis and cell cycle analysis,and Transwell assays for migration and invasion.A xenograft tumor model was established to evaluate tumor proliferation,im-munohistochemistry was performed to detect the protein expression of AKT in tumor tissues,and Western blot was used to analyze the expression levels of AKT,β-catenin,N-cadherin and Slug.RESULTS:A total of 108 overlapping targets were identified between Bai and pancreatic cancer.Among these,7 core targets were recognized,including proto-onco-gene tyrosine-protein kinase Src,heat shock protein 90 alpha family class A member 1(HSP90AA1),estrogen receptor 1(ESR1),tumor protein p53(TP53),epidermal growth factor receptor(EGFR),AKT1,and mitogen-activated protein ki-nase 3(MAPK3).The GO analysis revealed significant enrichment in oxidative stress response,protein phosphorylation,and serine/threonine kinase activity.The KEGG analysis primarily enriched the PI3K/AKT,MAPK and Ras signaling pathways.The MTT and colony formation assays showed that Bai inhibited the viability of Aspc-1 and Bxpc-3 cells in a dose-dependent manner(72 h IC50 values were 73.6 μmol/L and 83.4 μmol/L,respectively)and reduced cell colony for-mation(P<0.05 or P<0.01).Flow cytometry confirmed that Bai induced apoptosis of Aspc-1 and Bxpc-3 cells(P<0.01)and blocked the cell cycle at the G0/G1 phase(P<0.05 or P<0.01).Transwell experiments indicated that Bai inhibited the migration and invasion of Aspc-1 and Bxpc-3 cells(P<0.05 or P<0.01).In vivo,Bai significantly inhibited the growth of Aspc-1 cell xenograft tumors(P<0.01).Immunohistochemistry revealed a significant reduction in AKT expression in tu-mor tissues(P<0.01),and Western blot showed decreased expression of AKT,β-catenin,N-cadherin and Slug in both Aspc-1 and Bxpc-3 cells(P<0.01).CONCLUSION:Baicalein inhibits pancreatic cancer cell proliferation,migration,and invasion,potentially through down-regulation of AKT,β-catenin,N-cadherin,and Slug expression.

Objective To analyze the relationship between clinical drug utilization and the risk of nosocomial infections among hospitalized patients,and provide evidence for the prevention and control of nosocomial infections.Methods This study adopted a retrospective case-control design.The case group included 209 patients with nosocomial infection reported from January 2023 to December 2023 in a tertiary hospital.The control group included 209 patients without nosocomial infection during the same period.The patients in the control group were selected by stratified sampling based on Charlson Comorbidity Index(CCI).Results Univariate analysis showed that proton pump inhibitors,antacids,immunosuppressants and prior antimicrobial combination therapy increased the risk of nosocomial infection(P＜0.05).Multivariate log-binomial regression analysis showed that proton pump inhibitors,immunosuppressive drugs,and prior antimicrobial combination therapy were correlated with nosocomial infection.The corresponding relative risk(RR)was 1.31(95％CI:1.07-1.60),1.40(95％CI:1.02-1.91),and 1.66(95％CI:1.01-2.74),respectively.Further analysis indicated that the patients with nosocomial infection had longer time in use of proton pump inhibitors and prior antimicrobial combination therapy than the patients in the control group(Z=-6.331,P＜0.001;Z=-2.667,P=0.008).The trend Chi-square test showed that there was a dose-response relationship for proton pump inhibitors(x2=73.869,P＜0.001),immunosuppressive drugs(x2=16.530,P＜0.001),and prior antimicrobial combination therapy(x2=35.107,P＜0.001).Conclusions The use of immunosuppressants,proton pump inhibitors and antimicrobial combination therapy increases the risk of nosocomial infections in hospitalized patients.The prolonged use of these drugs will further increase the risk of nosocomial infection.

Background: SM-like (LSM) genes a family of RNA-binding proteins, are involved in mRNA regulation and can function as oncogenes by altering mRNA stability. However, their roles in B-cell progression and tumorigenesis remain poorly understood. Methods: We analyzed gene expression profiles and overall survival data of 123 patients with mantle cell lymphoma (MCL). The LSM index was developed to assess its potential as a prognostic marker of MCL survival. Results: Five of the eight LSM genes were identified as potential prognostic markers for survival in MCL, with particular emphasis on the LSM.index. The expression levels of these LSM genes demonstrated their potential utility as classifiers of MCL. The LSM.index-high group exhibited both poorer survival rates and lower RNA levels than did the overall transcript profile. Notably, LSM1 and LSM8 were overexpressed in the LSM.index-high group, with LSM1 showing 2.5-fold increase (p < 0.001) and LSM8 depicting 1.8-fold increase (p < 0.01) than those in the LSM.index-low group.Furthermore, elevated LSM gene expression was associated with increased cell division and RNA splicing pathway activity. Conclusions The LSM.index demonstrates potential as a prognostic marker for survival in patients with MCL. Elevated expression of LSM genes, particularly LSM1 and LSM8, may be linked to poor survival outcomes through their involvement in cell division and RNA splicing pathways. These findings suggest that LSM genes may contribute to the aggressive behavior of MCL and represent potential targets for therapeutic interventions.
