Objective To investigate vascular endothelial growth factor-c (VEGF-C) and vascular endothelial growth factor receptor-3(VEGFR-3) mRNA expression, microvessels density (MVD) and lymphatic microvessels density (LVD) in human hepatocellular carcinoma and normal liver tissue. Try to illuminate the relationship among VEGF-C,VEGFR-3,MVD,LVD and the clinical pathological features of hepatocellular carcinoma. Methods Liver tissue of 60 cases definitely diagnosed as hepatocellular carcinoma and 20 normal cases were collected. VEGF-C and VEGFR-3 mRNA expression were examined by RT-PCR, MVD and LVD were examined by immunohistochemistry staining. Relationship between these indexes and clinical pathological features of hepatocellular carcinoma was also analysed. Results VEGF-C and VEGFR-3 mRNA expression, MVD and LVD in hepatocellular carcinoma were higher than those in normal liver tissue (P<0.01); In hepatocellular carcinoma tissue, expression of VEGF-C mRNA positively related with VEGFR-3 mRNA, MVD and LVD(P<0.01). VEGF-C and VEGFR-3 expression positively related with portal vein tumor thrombus, intrahepatal metastasis and lymph node metastasis (P<0.01). MVD positively related with portal vein tumor thrombus and intrahepatal metastasis (P<0.01). LVD positively related with lymph node metastasis (P<0.01). Conclusion VEGF-C and VEGFR-3 expression increase in hepatocellular carcinoma tissue. They might play roles in tumor invasion and metastasis by inducing angiogenesis and lymphangiogenesis.

Objective: To investigate the neural connections between Shenmen (HT7)-heart and the brain by observing the tracing viruses co-labeled brain nuclear groups after injection of the pseudorabies viruses (PRV), the reverse transsynaptic virus tracer carrying different fluorescent protein genes, into the myocardium and Shenmen (HT7) point, respectively.Methods: Pseudorabies virus 531 (PRV531) carrying the green fluorescent protein gene and pseudorabies virus 724 (PRV724) carrying the red fluorescent protein gene were injected into the left ventricular wall and Shenmen (HT7) point area of the left forelimb of six C57BL/6 mice, respectively. After 120 h, whole brain tissue was extracted under 4％ paraformaldehyde perfusion to prepare brain sections. Neuronal co-labeling with the tracing viruses was observed under fluorescence microscopy. Results: Co-labeled signals from the mouse ventricular wall and Shenmen (HT7) point region were found at all levels of the mouse central nervous areas, such as the cerebral cortex, hypothalamus, midbrain, pons, and medulla oblongata. The number of co-labeled neurons was higher in the primary motor area, the hypothalamic paraventricular nucleus, the subceruleus nucleus, and the paramedian reticular nucleus. Conclusion: There is a neural connection between Shenmen (HT7), the heart, and the brain, which may be most closely related to the autonomic nervous system.
