001) (Fig. 3). Histopathologically, CD4+ and CD8+ lymphocytes were found more in the white pulp than in

the red pulp. The results of the clinicopathological analysis showed that the CD4+/CD8+ ratio in spleens with HCV-related liver cirrhosis and hypersplenism was higher than that in the spleens of control group 3 (P = 0.06). The FOXP3/CD4+ ratio in control group 3 was higher than that in cases of hypersplenism (P < 0.05), and no significant differences in the granzyme B/CD8+ ratio (P = 0.82) were observed between the splenectomy group and control group 3 (data not shown). The ratio of CD4+ T cells to all lymphocytes and the CD4+/CD8+ ratio in PB samples obtained from 26 patients before splenectomy were significantly higher than those from control group 2 (P < 0.01, P < 0.05). In contrast, the INCB018424 solubility dmso ratio of CD4+ T cells to all lymphocytes significantly decreased 1 year after splenectomy (P < 0.001), while the ratio of CD8+ T cells to all lymphocytes slightly increased (P = 0.07), resulting

in a significant decrease in the CD4+/CD8+ ratio (P < 0.001) (Fig. 4). Transforming growth factor-β levels were higher in PB samples from patients with HCC than in those without. TGF-β1 levels slightly increased in PB samples 1 month after splenectomy, then decreased, and subsequently returned to the level measured before splenectomy Dorsomorphin chemical structure in 1 year. In the splenectomy group, the CD4+/CD8+ ratio in PB had a significant positive correlation with the CD4+/CD8+ ratio in the spleen (P < 0.05), 上海皓元医药股份有限公司 and was also positively associated with the liver (P = 0.07). As a result, a significant positive correlation was observed between the CD4+/CD8+ ratio in the spleen and that in the liver (P < 0.05) (Fig. 5). We compared the CD4+/CD8+ ratio between PB obtained pre-splenectomy and 1 month after splenectomy (n = 19). The median of differences between pre-splenectomy and 1 month after splenectomy was 0.5. The occurrence of HCC was significantly lower in cases in which the difference in the CD4+/CD8+ ratio between the perioperative period and 1 month later was over 0.5 (≥0.5 vs <0.5, P < 0.05)

(Fig. 6a). A positive correlation in PB was observed between the CD4+/CD8+ ratio before splenectomy and differences in the CD4+/CD8+ ratio between pre-splenectomy and 1 month after splenectomy (P < 0.001). As the median of the preoperative CD4+/CD8+ ratio was 1.7, the postoperative (1 month after splenectomy) CD4+/CD8+ ratio significantly decreased in groups in which the preoperative value was larger than 1.7 (Fig. 6b,c). PREVIOUS STUDIES HAVE shown that splenectomy was effective in improving pancytopenia, the decompression of portal hyperpressure and liver function.[1, 2, 27, 28] Morinaga et al. reported that splenectomy significantly improved liver fibrosis with a reduction in plasma TGF-β1 levels in the rat.
