ABSTRACT

Objective To examine the relationship between serum vitamin D level and immune imbalance in advanced schistosomiasis patients with liver fibrosis. Methods A total of 120 advanced schistosomiasis patients with liver fibrosis that were admitted to the Department of Schistosomiasis of The First Hospital of Jiaxing City from May 2016 to September 2018 were recruited as the observation group, and 50 healthy volunteers randomly sampled from the hospital during the same period served as the control group. The serum IgG antibody, IgA antibody, C3 complement, C4 complement, CD4+ cell proportion, CD8+ cell proportion, 25-hydroxyvitamin D [25(OH)D] levels were compared between the two groups. Liver fibrosis was classified into grade I, II and III according to the classification criteria of liver fibrosis by ultrasonography, and the serum IgG antibody, IgA antibody, C3 complement, C4 complement, CD4+ proportion, CD8+ proportion, 25(OH)D levels were compared among patients with grade I, II and III liver fibrosis. In addition, all patients were classified into the sufficient group, the insufficient group and the deficient group according to the serum vitamin D level, and the serum IgG antibody, IgA antibody, C3 complement, C4 complement, CD4+ proportion, CD8+ proportion, 25(OH)D levels were compared among these three groups. Moreover, the associations of the serum vitamin D level with these immune indicators were examined. Results The 120 advanced schistosomiasis patients with liver fibrosis included 58 men and 62 women, and had a mean age of (72.00 ± 3.00) years. There were 32 cases with grade I liver fibrosis, 46 cases with grade II liver fibrosis, and 42 cases with grade III liver fibrosis. There were no significant differences between the observation group and the control group in terms of serum D-dimer, total cholesterol (TC), triglyceride (TG), C3 complement or C4 complement levels (t = 2.467, 0.322, 0.790, -2.432 and -2.630, all P values > 0.05); however, there were significant differences seen in alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood calcium, blood phosphorus, IgG antibody, IgA antibody, CD4+ proportion, CD8+ proportion, and 25(OH)D levels (t = 5.130, 6.382, -1.341, 2.361, 8.708, 11.783, -2.995, -6.543 and -3.022, all P values < 0.05). In addition, there were significant differences in AST, ALT, blood phosphorus, IgA antibody, C3 complement, CD8+ cell proportion and 25(OH)D levels among patients with grades I, II and III liver fibrosis (F = 19.704, 16.254, 62.669, 49.347, 5.430, 5.434 and 5.783, all P values < 0.05). There were significant differences in ALT, blood phosphorus, IgA antibody, CD8+ cell proportion and 25(OH)D levels between patients with grades I and III liver fibrosis (all P values < 0.05), and significant differences were seen between patients with grades II and III liver fibrosis in terms of blood phosphorus, IgA antibody and CD8+ cell proportion (all P values < 0.05), while there was a significant difference in the CD8+ cell proportion between patients with grades I and II liver fibrosis (P < 0.05). Moreover, there were significant differences among the sufficient, insufficient and deficient groups in terms of IgG antibody, IgA antibody, C3 complement, CD4+ cell proportion and CD8+ cell proportion (F = 13.303, 59.623, 8.698, 9.969 and 12.805, all P values < 0.05), and there was a significant difference in the CD8+ cell proportion between the insufficient and deficient groups (P < 0.05). Pearson correlation analysis revealed that serum 25(OH)D level were negatively associated with IgG and IgA antibody levels (r = -0.754 and -0.773, both P values < 0.05), and positively associated with C3 complement, CD4+ cell proportion and CD8+ cell proportion in advanced schistosomiasis patients with liver fibrosis (r = 0.827, 0.850 and 0.830, all P values < 0.05). Conclusion Immune imbalance occurs in advanced schistosomiasis patients with liver fibrosis, and serum vitamin D level may correlate with immune imbalance in advanced schistosomiasis patients with liver fibrosis.

ABSTRACT

Objective To compare the expression of serum vitamin D in advanced schistosomiasis patients with grade I and II hepatic fibrosis, and to preliminarily examine its associations with the internal diameter of the main portal vein and progression of hepatic fibrosis. Methods The medical records of 126 advanced schistosomiasis patients with grade I and II hepatic fibrosis referred to Jiaxing First Hospital from March 2012 to September 2015 were retrospectively analyzed. The internal diameter of the main portal vein and serum 25-hydroxyvitamin D3 [25(OH)D3] level were measured. The progression of hepatic fibrosis was followed up, and the serum vitamin D level was compared between patient with disease progression and stable disease. Results The 126 advanced schistosomiasis patients included 72 men and 54 women, and had ages of 62 to 80 years. There were 58 cases with grade I hepatic fibrosis and 68 cases with grade II hepatic fibrosis. There were significant differences between patients with grade I and II hepatic fibrosis in terms of hemoglobin, white blood cell count, prothrombin time, international normalized ratio, activated partial thromboplastin time, fibrinogen or 25(OH)D3 level (all P > 0.05), and significant differences were seen in alanine aminotransferase, aspartate aminotransferase, blood calcium, blood phosphorus levels and the internal diameter of the main portal vein (all P values < 0.05). In addition, a lower serum 25(OH)D3 level was detected in patients with broadened internal diameter of the main portal vein than in those with normal internal diameter of the main portal vein [(19.08 ± 1.36) nmol/L vs. (25.61 ± 6.69) nmol/L, P < 0.05]. Following 3-year follow-up, there were 73 cases with progression of hepatic fibrosis, and a significantly lower serum vitamin D level was found in patients with disease progression than in those with stable disease [(20.00 ± 0.81) nmol/L vs. (25.47 ± 5.91) nmol/L, P < 0.05]. Conclusions Vitamin D deficiency is common in advanced schistosomiasis patients with hepatic fibrosis, and it may be associated with the internal diameter of the main portal vein and the progression of hepatic fibrosis disease.

ABSTRACT

Objective Vascular endothelial growth factor C (VEGFC) and cortactin (CTTN) have been found to be closely related to the growth of esophageal squamous cell carcinoma (ESCC), but their specific relationship has not been clearly defined up to the present time. This study aimed to investigate the effects of VEGFC and CTTN on the proliferation and apoptosis of ESCC cells. Methods Human ESCC TE1 cells were treated with normal culture medium (the blank control group), MATE transfection reagent ( the MATE group), negative control RNA and MATE reagent (the negative control group), positive control RNA and MATE reagent (the positive control group), VEGFC siRNA and MATE transfection reagent (the VEGFC siRNA group), and CTTN siRNA and MATE transfection reagent (the CTTN siRNA group). The proliferation of the ESCC TE1 cells in different groups was detected by CCK-8 assay and their apoptosis determined by flow cytometry. Results Compared with the blank control group, the ESCC cells of the VEGFC siRNA and CTTN siRNA groups showed significantly decreased expressions of VEGFC mRNA (1.00 ± 0.00 vs 0.13 ± 0.01, P < 0.05) and CTTN mRNA (1.00 ± 0.00 vs 0.29 ± 0.02, P < 0.05). The proliferation rate of the ESCC cells was remarkably lower in the VEGFC siRNA and CTTN siRNA than in the other groups (P < 0.05), and even lower in the VEGFC siRNA than in the CTTN siRNA group ([31.26 ± 5.25]% vs [46.99 ± 4.82]%, P < 0.05), but their apoptosis rate was markedly higher in the former than in the latter group ([48.41 ± 5.37]% vs [36.78 ± 4.29]%, P < 0.05). Conclusion Interfering with the expressions of VEGFC and CTTN can inhibit the proliferation and promote the apoptosis of ESCC cells, and VEGFC has an even better effect than CTTN.
