Aim To explore the role of zinc transporter 6(SLC30A6)on the proliferation,migration and inva-sion capabilities of hepatocellular carcinoma(HCC)cell line Huh7,and to identify potential traditional Chi-nese medicine(TCM)small-molecule inhibitors targe-ting SLC30A6 from the China Natural Products Data-base(CNPD)using virtual screening techniques.Methods The expression levels,clinical characteris-ticsand prognostic value of SLC30A6 in HCC were pre-dicted based on TCGA and ICGC datasets.SLC30A6 was knocked down in Huh7 cells using lentiviral trans-fection.The effects on cell proliferation,migration,and invasion were assessed using CCK-8,EdU,wound heal-ing,and Transwell assays.The regulation of HCC cancer stem cell markers(CD44,CD133,CD90)by SLC30A6 was also examined.Based on the CNPD,a docking-based virtual screening strategy was employed,including high-throughput virtual screening,standard precision virtual screening,and high-precision virtual screening,to identify the potential drug candidates with high specificity and favorable drug-likeness.Results SLC30A6 expression was upregulated in HCC tissues.Higher SLC30A6 levels were associated with advanced pathological stages,histological grades,alpha-fetopro-tein(AFP)levels,vascular invasion,and poor progno-sis in HCC patients.SLC30A6 knockdown significantly inhibited the proliferation,migration,and invasion of Huh7 cells and reduced the levels of HCC cancer stem cell markers.Virtual screening identified six potential TCM small-molecule inhibitors.Conclusions SLC30A6 can regulate the proliferation,migrationand invasion of HCC cells.SLC30A6 may serve as a poten-tial prognostic biomarker and therapeutic target for HCC.

Objective To investigate the expression levels and clinical significance of B7 homolog 3(B7-H3),peroxiredoxin 1(PRDX1),and thioredoxin(TRX)in the serum and tissues of patients with ulcerative colitis(UC)and UC-associated colorectal cancer(UC-CRC).Methods A total of 108 patients with UC who underwent examination in our hospital between January 2019 and December 2023 were enrolled in the UC group.Additionally,108 patients with UC-CRC who were examined in our hospital were included in the UC-CRC group.Furthermore,108 individuals without any abnormalities detected during colonoscopy were recruited as the control group.The serum levels of B7-H3,PRDX1,and TRX were quantified using enzyme-linked immunosorbent assay(ELISA).The expression of B7-H3,PRDX1,and TRX in tissues from UC-CRC and UC patients was assessed by immunohis-tochemistry.The diagnostic performance of serum B7-H3,PRDX1,and TRX levels for UC-CRC was evaluated by constructing receiver operating characteristic(ROC)curves.Results Compared with the control group,the serum expression levels of B7-H3,PRDX1,and TRX in both the UC group and the UC-CRC group were significantly elevated in sequence(P<0.05).In comparison to the resting UC group,the serum expression levels of B7-H3,PRDX1,and TRX in the episodic UC group also increased significantly(P<0.05).Furthermore,compared with UC patients,the positive expression rates of B7-H3,PRDX1,and TRX in the tissues of UC-CRC patients were markedly higher(P<0.05).The combination of serum B7-H3,PRDX1,and TRX demonstrated the highest AUC for diagnosing UC-CRC patients,outperforming the individual diagnostic performance of each biomarker(Z combination-B7-H3=2.829,P=0.005,Z combination-PRDX1=2.544,P=0.011,Z combination-TRX=3.673,P<0.001).Conclusion B7-H3,PRDX1,and TRX are significantly overexpressed in both the serum and tissues of UC-CRC patients,and their combined evaluation holds potential as a diagnostic tool for detecting the development of UC-CRC.

The renin-angiotensin-aldosterone system (RAAS) is crucial for regulating blood pressure and maintaining fluid balance, while clock genes are essential for sustaining biological rhythms and regulating metabolism. There exists a complex interplay between RAAS and clock genes that may significantly contribute to the development of various cardiovascular and metabolic diseases. Although current literature has identified correlations between these two systems, the specific mechanisms of their interaction remain unclear. Moreover, the interaction patterns under different physiological and pathological conditions need further investigation. This review summarizes the synergistic roles of the RAAS and clock genes in cardiovascular diseases, explores their molecular mechanisms and pathophysiological connections, discusses the application of chronotherapy, and highlights potential future research directions, aiming to provide novel insights for the prevention and treatment of related diseases.

Objective:To explore the effects of early vitamin D supplementation on the immune function of premature infants.Methods:A total of 150 premature infants admitted to Hebei Cangzhou Hospital of Integrated Traditional Chinese and Western Medicine from January 2022 to March 2023 were enrolled perspectively, they were divided into the intervention group (75 cases) and the control group (75 cases) by the random number table method. The control group received formula milk intervention, and the intervention group received early vitamin D supplementation treatment on the basis of the control group. The course of treatment was 14 d. The levels of serum 25-hydroxyvitamin D [25- (OH) D], immunoglobulin (Ig), T cell subsets, complement C3, C4, and serum interleukin (IL)-1β and IL-10 were compared between the two groups before and after intervention.Results:The level of serum 25- (OH) D in the intervention group at 14 d after intervention was higher than that in the control group, the level of IL-1β was lower than that in the control group: (30.13 ± 6.00) nmol/L vs. (26.84 ± 5.79) nmol/L, (0.54 ± 0.20) ng/L vs. (0.65 ± 0.23) ng/L, there were statistical differences ( P<0.05). The levels of CD 3+, CD 4+, complement C3, C4, and IL-10 in the intervention group were higher than those in the control group at 14 d after intervention: 0.692 ± 0.043 vs. 0.632 ± 0.038, 0.400 ± 0.027 vs. 0.369 ± 0.026, (0.98 ± 0.26) g/L vs. (0.84 ± 0.24) g/L, (0.20 ± 0.05) g/L vs. (0.16 ± 0.04) g/L, (13.82 ± 3.64) ng/L vs. (11.36 ± 2.93) ng/L, there were statistical differences ( P<0.05). There were no statistically significant differences in the levels of IgA, IgM and IgG between the two groups before and after intervention ( P>0.05). Conclusions:Early vitamin D supplementation can significantly improve T cell subsets and regulate IL-1β/IL-10 levels in premature infants.
