ABSTRACT
To analyze the impact of hepatitis B virus (HBV) infection on liver function of patients after hematopoietic stem cell transplantation (HSCT), the transplantation outcome of 48 patients infected with HBV prior to transplantation among 185 patients received HSCT was investigated retrospectively. The results showed that during a follow-up for 6 months after HSCT, the alanine aminotransferase (ALT) peak average values of the patients with HBsAg(+), HBsAb(+) and control groups were (281.6 ± 414.6), (95.4 ± 79.9) and (65.1 ± 44.2) U/L, respectively. The incidences of abnormal liver function of the patients with HBsAg(+), HBsAb(+) and control groups were 61.54%, 40.00% and 30.23% respectively. There were no significant differences between any two groups (P > 0.05). The lethality of those patients at late period after transplantation was not related to HBV infection. The hepatocirrhosis and hepatocarcinoma caused by HBV infection have not become major problems in long-term survivors. It is concluded that in HBsAg(+) patients received HSCT, the damage of liver function is more severe than control group, possibly increasing the development of abnormal liver function. The measures against the liver function damage should be taken. The prophylactic administration of ganciclovir for virus may be effective to prevent the activation of HBV.

<p><b>OBJECTIVE</b>To investigate the expressions of RhoC, CD44v6 and ICAM-1 in gastric cancer and their correlations.</p><p><b>METHODS</b>SABC immunohistochemistry was used to detect the expressions of RhoC, CD44v6 and ICAM-1 in the specimens from 40 cases with gastric cancer. Their correlations were reviewed by clinicopathological data.</p><p><b>RESULTS</b>The expression of RhoC, CD44v6 and ICAM-1 were not correlated with tumor differentiation and invasion depth (P> 0.05), but significantly correlated with lymph metastasis and pTNM stage (P< 0.05). There was a significant correlation between the expression of RhoC and the expression of CD44v6 or ICAM-1 (r=0.355, P=0.006; r=0.354, P=0.003) respectively. If RhoC was positive-expressed, and either of CD44v6 or ICAM-1 was positive-expressed, the sensitivity and the specificity for predicting the lymphatic metastasis was 93.75%, 62.5% respectively.</p><p><b>CONCLUSIONS</b>The positive expressions of RhoC, CD44v6 and ICAM-1 are useful biological markers for predicting the metastatic potential of gastric cancer. The combined detection of three markers is a useful method for predicting lymphatic metastasis of gastric cancer.</p>
