RESUMEN
The present study aims to investigate the effects of soluble endoglin (sEng) on invasive ability of cultured cytotrophoblasts of first trimester of pregnancy. Cytotrophoblasts of normal 6 to 8-week pregnancy were cultured by trypsin digestion method, and were incubated with cell culture medium without (control group) and with 10 μg/L sEng (sEng group), respectively for 24 h. The invasive ability was determined by transwell invasion assay, and expressions of MMP-2, MMP-9 mRNA and protein were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot, respectively. The results showed that the invasive ability of cytotrophoblasts in sEng group was lower than that in control group (P < 0.05). Compared with control group, the expressions of MMP-2 and MMP-9 mRNA and protein of cytotrophoblasts were significantly lower (P < 0.05). In conclusion, sEng may participate in the genesis of preeclampsia by affecting the invasive ability of cytotrophoblasts through regulation of the expression of MMP-2 and MMP-9.

<p><b>OBJECTIVE</b>To research the effect of a complex prescription of Chinese crude drug with the function of strengthening body resistance and disintoxication disintoxication in patients with HCC of post-TACE.</p><p><b>METHOD</b>45 patients with HCC of post-TACE, as the treatment group, were treated by a complex prescription of Chinese crude drug with the function of strengthening body resistance and disintoxication disintoxication and routine methods of protecting liver. Other 37 patients, as the control group, with the same clinical feature were treated by routine methods of protecting liver only. In the later 1 month, accumulated points of clinical symptom, hepatic function and AFP were observed in all of the patients. And the clinical effect of the two groups was compared.</p><p><b>RESULT</b>One week later, in the treatment group, there is no improvement in anorexia but nausea, abdominal distention and lassitude were improved more obviously than pretherapy in both a week and one month later (P < 0.01 or P <0.05). In the control group, anorexia were improved a week later (P <0.05), but there is no improvement in nausea, abdominal distention and lassitude at the same time, and one month later all of the indexes above improved (P <0.01 or P <0.05). Accumulated points of clinical symptom was decreased more obviously in the treatment group than in the control group in both a week and one month later (P <0.05). At the end of the therapy, in the both groups, ALT, TBIL and AFP all improved except ALB, (P <0.01 or P <0.05). And TBIL improved more obviously in the treatment group than in the control one month later (P <0.05).</p><p><b>CONCLUSION</b>This complex prescription of Chinese crude drug can lighten the adverse reaction of post-TACE. And also it can promote the recovery of liver function and evaluate the quality of lives of such patients.</p>

<p><b>OBJECTIVE</b>To research the treatment effect of complex prescription of Chinese crude drug in BALB/c athymic mice with human liver cancer, which were built by Bel-7402.</p><p><b>METHOD</b>48 male BALB/c athymic mouse models were built by Bel-7402 with an indirect method. After 24 hours of postoperation, the 48 athymic mice were distributed randomly into 4 groups which were treated by intragastric administration with complex prescription of Chinese crude drug that had been deliquated into 3 groups by the different density as the low, middle, and high and FT207 (Tegafur) for 4 weeks. At last, athymic mice were put to death and PTEN was detected in hepatic tissue, latero-cancer tissue and cancer tissue by immunohistochemistry (PowerVision Two-Step Histostaining Reagent).</p><p><b>RESULT</b>All of the 48 athymic mice survived 12 to 28 days (Ms 24 days) and every mouse with liver cancer demonstrated by dissection. The result of immunohistochemistry represents that the intensity of PTEN in latero-cancer tissue is the highest, and then the hepatic tissue, the lowest is cancer tissue, P < 0.01. It also represents that the intensity of PTEN in treatment groups (A, B, C) is more higher than the control group (D), P < 0.05 or P < 0.01, and group B is the highest in the treatment groups, P < 0.05 or P < 0.01. However, there is no significant statistic difference between group A and group C.</p><p><b>CONCLUSION</b>The higher expression of PTEN in the laterocancer tissue can represent the protective reaction of stress of the organism. And anticancer effect of this complex prescription of Chinese crude drug relates to an eligible density of it. Mechanisms of this complex prescription of Chinese crude drug healing HCC may partially be explained by enhancing the expression of PTEN in liver.</p>
