In order to investigate the role of Twist gene in the metastasis of hepatocellular carcinoma (HCC), total RNA was respectively extracted from three HCC cell strains with different metastatic potentials, HepG2, MHCC-97L and MHCC-97H. The first strand cDNA was synthesized by reverse transcription, which was then used as template to perform fluorescent quantitative polymerase chain reaction (FQ-PCR). The quantity of Twist gene expression was normalized by that of the housekeeping gene, GAPDH for each sample. ANOVA was used to estimate the relationship between Twist gene and metastasis potential of HCC. The results showed that the normalized initial cDNA concentrations of Twist gene in HepG2, MHCC-97L and MHCC-97H were (9.45+/-0.25)x10(-4), (1.82+/-0.41)x10(-3), (3.06+/-0.62)x10(-3), respectively. FQ-PCR revealed significant differences in the expression level of Twist among HCC cell strains with different metastatic potentials. It was concluded that high expression level of Twist was closely associated with more aggressive behaviors of HCC. Twist provides a novel indicator for HCC metastasis.

In order to investigate the role of Twist gene in the metastasis of hepatocellular carcinoma (HCC), total RNA was respectively extracted from three HCC cell strains with different metastatic potentials, HepG2, MHCC-97L and MHCC-97H. The first strand eDNA was synthesized by reverse transcription, which was then used as template to perform fluorescent quantitative polymerase chain reaction (FQ-PCR). The quantity of Twist gene expression was normalized by that of the housekeeping gene, GAPDH for each sample. ANOVA was used to estimate the relationship between Twist gene and metastasis potential of HCC. The results showed that the normalized initial eDNA concen- trations of Twist gene in HepG2, MHCC-97L and MHCC-97H were (9.45±0.25)×104, (1.82±0.41)×10-3, (3.06±0.62)×10-3, respectively. FQ-PCR revealed significant differences in the ex- pression level of Twist among HCC cell strains with different metastatic potentials. It was concluded that high expression level of Twist was closely associated with more aggressive behaviors of HCC. Twist provides a novel indicator for HCC metastasis.

Objective To investigate the clinical effects and complications of endoscopic tandem ligation and hemorrhoids ligation.Methods Clinical data of 120 patients with grade Ⅰ～Ⅲ internal hemorrhoids who were hospitalized due to hematochezia from November 2021 to March 2023 were retrospectively analyzed.According to the different surgical methods,60 patients who received endoscopic hemorrhoid ligation were divided into control group;60 patients who underwent endoscopic tandem ligation were divided into treatment group.The effective rate of hemorrhoidal hemorrhage,the effect of internal hemorrhoidal prolapse and the incidence of postoperative complications were compared between two groups within 6 months after operation.Results The effective rate of internal hemorrhoidal bleeding was 100.00％in both groups,and the efficacy of the treatment group in the treatment of degree Ⅱ internal hemorrhoidal prolapse was similar to that in the control group(P＞0.05),but the treatment group was significantly better than the control group in the treatment of degree Ⅲ internal hemorrhoidal prolapse(P＜0.01),the postoperative anal pain in the treatment group was significantly more than the control group(P＜0.05);There were no significant differences in postoperative perianal pain,urinary retention,and abnormal defecation between the two groups(P＞0.05).No thrombotic external hemorrhoids occured in two groups.Conclusion The short-term efficacy of endoscopic tandem ligation and hemorrhoidal ligation in the treatment of internal hemorrhoidal bleeding is similar and both achieved satisfactory results,the short-term efficacy of the two in the treatment of degree Ⅱ internal hemorrhoidal prolapse is similar,the short-term efficacy of the former in the treatment of degree Ⅲ internal hemorrhoidal prolapse is significantly better,the feeling of anal heaviness in the treatment group is more than that in the control group,and there is no striking difference in the other complications.
