Objective To elucidate the changes in the gut microbiota and molecular mechanism of huaier in enhancing the efficacy of oxaliplatin (OXA) chemotherapy in gastric cancer (GC). Methods The effects of huaier on the gut microbiota structure and intestinal barrier function in MKN45-bearing mice were analyzed by using 16S rRNA sequencing, RT-qPCR, and IHC. UPLC-MS and network pharmacology, as well as in vivo experimental approaches, were employed to investigate the key bioactive constituents of huaier systematically and elucidate the underlying mechanisms by which huaier exerts therapeutic effects against GC. The expression of the PI3K/AKT/SREBP pathway was detected in cancer cells and tissues via Western blot analysis. The safety profile of huaier combined with OXA was verified through serum biochemistry and HE-stained tissue section analyses. Results Huaier inhibited the PI3K/AKT/SREBP pathway by increasing the abundance of Akkermansia muciniphila, reduced lipid droplet deposition, and ultimately enhanced the sensitivity to OXA in the treatment of GC. Conclusion This study demonstrates the value of huaier in gastric cancer treatment by enhancing chemosensitivity and provides novel insights into its systemic therapeutic effects through molecular mechanisms and gut microbiota modulation.

Hospital caregivers,as crucial auxiliary groups in the healthcare system,face persistent stigmatization rooted in sociocultural and institutional dynamics,leading to diminished professional dignity and distorted service behaviors.This paper explores the social construction and cultural reproduction mechanisms underlying such stigmatization,revealing how internalized stigma and service alienation reinforce each other.Drawing on ethical and structural analysis,the study proposes a dual-path the-oretical framework integrating psychological empowerment and institutional enfranchisement.By enhancing individual resilience and reshaping organizational structures,this integrated approach seeks to reconstruct the occupational identity of care workers and foster an ethical breakthrough in service delivery,ultimately promoting the de-stigmatization and sustainable development of the profession.

Objective:To research the mechanism of the regulation of homeobox B8(HOXB8)for lysine demethylase 6B(KDM6B)-mediated CCAAT/enhancer binding protein α(C/EBPα)axis on the metastasis of high-grade serous ovarian cancer(HGSOC),so as to provide references for the study of the pathogenesis of HGSOC patients.Methods:The tumor tissue samples and corresponding adjacent normal tissue samples of HGSOC patients admitted to Wuhan Hospital of Traditional Chinese and Western Medicine from June to December 2024 were selected,and cell lines SKOV3 and A2780 of ovarian cancer were collected.Real-time fluorescence quantitative polymerase chain reaction(RT-qPCR)was adopted to detect the mRNA levels of KDM6B in HGSOC tumor tissues and its corresponding adjacent tissues.Western blot assay and immunohistochemistry were adopted to detect the expressions of KDM6B protein in the tissue.The A2780 cells of ovarian cancer were divided into the oe-HOXB8 group that was transfected by the HOXB8 overexpression vector,and the oe-NCHOXB8 group with the negative control(NC)vector.The SKOV3 cells of ovarian cancer were divided into the si-HOXB8 group that was transfected by the HOXB8 small interference sequence,and the si-NCHOXB8 group with negative control sequence.The transfected KDM6B was divided into the si-KDM6B group with small interference sequence and the oe-KDM6B group transfected with overexpression vector.The co-transfection HOXB8 and(or)KDM6B,C/EBPα were divided into si-HOXB8+si-KDM6B group and si-HOXB8+si-C/EBPα group of small interference sequence.The chromatin immunoprecipitation-qPCR(ChIP-qPCR)and dual-luciferase reporter gene assay were used to verify the mechanism that HOXB8 transcript and regulate KDM6B in SKOV3 and A2780 cells of ovarian cancer.The effects of overexpression or silencing of HOXB8 in A2780 and SKOV3 cells on the proliferation,invasion,migration and KDM6B expression of ovarian cancer cells were detected.The effects of overexpression or silencing of KDM6B in SKOV3 cells on the trimethylation modification of lysine 27 at histone H3(H3K27me3)and the expression of C/EBPα were detected.The effects of silencing KDM6B and C/EBPα on HOXB8-induced cell proliferation,invasion and migration were analyzed through functional rescue experiments.Results:In tumor tissues,the mRNA and protein expression levels of KDM6B were 1.02±0.03 and 1.02±0.04,respectively,which were significantly higher than those in the adjacent tissues,and the differences were statistically significant(t=62.440,38.737,P<0.01).The optical density value of proliferation,invasion rate and migration rate of A2780 cells in the oe-HOXB8 group that was transfected by the HOXB8 overexpression vector were respectively(1.74±0.15),(89.71±6.60)%and(85.33%±7.02)%,which were significantly higher than those in the oe-NCHOXB8 group,and the differences were statistically significant(t=7.778,7.353,4.759,P<0.01).The optical density value of proliferation,invasion rate and migration rate of SKOV3 cells in the si-HOXB8 group were respectively(0.54±0.06),(47.23±3.41)%and(43.20±3.12)%,all of which were significantly lower than those in the si-NCHOXB8 group,and the differences were statistically significant(t=9.400,8.615,9.040,P<0.01).The optical density value of proliferation,invasion rate and migration rate of SKOV3 cells in the si-HOXB8+si-KDM6B group were(1.04±0.09),(73.11±4.98)%and(68.65±4.45)%,respectively,which were significantly higher than those in the si-HOXB8 group,and the differences were all statistically significant(t=6.875,6.852,7.562,P<0.01).The optical density value of proliferation,invasion rate and migration rate of SKOV3 cells in the si-HOXB8+si-C/EBPα group were respectively(0.97±0.07),(75.87±5.12)%and(70.59±4.81)%,all of which were significantly higher than those in the si-HOXB8 group,and the differences were all statistically significant(t=6.355,7.500,7.884,P<0.01).Conclusion:HOXB8 can inhibit the C/EBPα expression and promote the HGSOC metastasis by regulating and controlling H3K27me3 modification of KDM6B-mediated C/EBPα histone.

Nonalcoholic fatty liver disease(NAFLD),also known as metabolic associated fatty liver disease(MAFLD),is one of the most common chronic liver diseases characterized by the fat accumulation in the liver and hepatocellular damage.Patients with NAFLD can manifest as simple fatty liver or non-alcoholic steatohepatitis(NASH)in the early stage,and can progress to hepatic fibrosis,hepatic cirrhosis,hepatic fail-ure,and hepatic carcinoma in the late stage.NAFLD has become the most common chronic liver disease,af-fecting more than 30%of the population worldwide,posing a threat to human health that cannot be ignored.However,the current research on NAFLD is still incomplete,and there is no ideal medication for the treat-ment of NAFLD.The clinical management of NAFLD lacks unified standards and evidence-based evidence,and the multiple comorbidities bring challenges to the clinical management of NAFLD.This article was aimed to review the research progress in the clinical management of NAFLD,including the diagnosis and non-invasive examination methods,evaluation and commonly used tools,treatments methods,advantages and disadvanta-ges,so as to provide a reference for the clinical management of NAFLD.

This article aimed to summarise the clinical experience of Professor XIONG Jibai in treating henoch-schonlein purpura （HSP） from the perspective of "simultaneous treatment of wind and blood". HSP was devided into acute phase and transitional phase in clinic. It was considered that the wind pathogen exists throughout the disease course， and the treatment is guided by the "four methods of treating blood" in TANG Rongchuan's Treatise on Blood Syndromes - Blood Vomiting （《血证论·吐血》）， which are stanching bleeding， expelling stasis， tranquilising blood， and tonifying blood. In the acute phase， wind-heat damaging collateral symdrome and blood-heat frenetic flow syndrome are common， which could be treated by the method of cooling blood to dispel wind， and eliminating stasis to stop bleeding， with self-prescribed modified Ziping Xiaofeng Powder （紫萍消风散）； in the transitional phase， syndrome of effulgent fire due to yin deficiency and syndrome of qi deficiency failing to control are common， which could be treated by the method of tranquilising blood and tonifying deficiency， with modified Zhibai Dihuang Decoction （知柏地黄汤） and Guipi Decoction （归脾汤）. At the same time， it is believed that wind-related medicinal has the function of eliminating stasis， stanching bleeding， and cooling blood， and the wind-related medicinal should be used throughout the treatment.

Objective:To analyze the effect of comprehensive rehabilitation intervention on the physical functioning of frail elderly persons.Methods:A total of 318 frail elderly persons were randomly divided into a control group ( n=164) and an observation group ( n=154) to test different interventions. Propensity score matching was used to balance the baseline information between the two groups 1∶1. A total of 200 cases were successfully matched, with 100 cases in each group. Both groups received drug treatment and routine nursing, while the observation group was additionally provided with comprehensive rehabilitation. Before and after 4 weeks of the treatment, both groups were evaluated using visual analogue scale (VAS) scoring for their perception of pain intensity, hand grip strength, gait speed, 6-minute walking distance (6MWD), 5 sit-up time, and the timed up and go test (TUGT). Results:There were no significant differences between the groups in any of the measurements before the experiment. Afterward, all of the outcome measures except gait speed were significantly better among the experimental group than among the controls, on average.Conclusions:Comprehensive rehabilitation can relieve pain, improve the walking, handgrip strength and exercise endurance of the frail elderly.

Objective To analyze the changes of serum humoral immunity related indicators, including immunoglobulins (Ig), complement and C-reactive protein (CRP) in patients with occupational medicamentose-like dermatitis due to trichloroethylene (OMDT) at different stages. Methods A total of 131 OMDT patients were selected as the study subjects using a retrospective analysis method, and liver function and humoral immunity related indicators were collected for analysis in the early stage and the recovery stage of the disease. Results The abnormality of liver function among study subjects was 89.3% (117/131) in the early stage of the disease, with mild, moderate, and severe liver damage accounting for 61.8%, 5.3%, and 22.1%, respectively. The levels of serum alanine aminotransferase, aspartate aminotransferase, γ-glutamyl transferase, total bilirubin, alkaline phosphatase, total bile acid, IgG and CRP in the early stage increased ( all P<0.01), while the level of serum cholinesterase and C3 decreased (both P<0.01) compared with the recovery stage. However, there was no significant difference in the level of serum albumin, globulin, IgA, IgM and C4 or albumin/globulin ratio between the early stage and the recovery stage (all P>0.05). The level of patients′ serum IgA in the group with severe liver function injury was lower than that in the group with mild to moderate liver function injury in the recovery stage (P<0.05). The level of serum C3 in the patients with severe liver function injury was lower than that in the group with mild to moderate liver function injury in the early stage (P<0.05). Conclusion Serum IgG and CRP levels increased and C3 level decreased in OMDT patients at the early stage of the disease, which was correlated with the degree of liver function injury. It is suggested that humoral immune response is involved in the autoimmune liver injury in OMDT patients.

The aim of this study was to produce recombinant porcine interferon gamma (rPoIFN-γ) by Chinese hamster ovarian (CHO) cells expression system and to analyze its antiviral activity. Firstly, we constructed the recombinant eukaryotic expression plasmid pcDNA3.1-PoIFN-γ and transfected into suspension cultured CHO cells for secretory expression of rPoIFN-γ. The rPoIFN-γ was purified by affinity chromatography and identified with SDS-PAGE and Western blotting. Subsequently, the cytotoxicity of rPoIFN-γ was analyzed by CCK-8 test, and the antiviral activity of rPoIFN-γ was evaluated using standard procedures in VSV/PK-15 (virus/cell) test system. Finally the anti-Seneca virus A (SVA) of rPoIFN-γ activity and the induction of interferon-stimulated genes (ISGs) and cytokines were also analyzed. The results showed that rPoIFN-γ could successfully expressed in the supernatant of CHO cells. CCK-8 assays indicated that rPoIFN-γ did not show cytotoxicity on IBRS-2 cells. The biological activity of rPoIFN-γ was 5.59×10⁷ U/mg in VSV/PK-15 system. Moreover, rPoIFN-γ could induced the expression of ISGs and cytokines, and significantly inhibited the replication of SVA. In conclusion, the high activity of rPoIFN-γ was successfully prepared by CHO cells expression system, which showed strong antiviral activity on SVA. This study may facilitate the investigation of rPoIFN-γ function and the development of novel genetically engineered antiviral drugs.
