RESUMEN
Objective To study the relativity between virtual touch tissue quantification(VTQ)and collagen percentage assay in the stiffness of primary liver cancer(PLC).Methods Forty patients with PLC were examined with virtual touch tissue quantification (VTQ)to obtain the shear wave velocity(SWV) before operation.These parameters were compared with collagen percentage assay counted with immunohistochemistry,and the correlation was statistically studied.Results Significant differences in mean SWV appeared between tumor tissues and background liver tissues of these PLC [2.82 ± 0.68 )m/s vs (1 .66±0.47)m/s,P <0.05].The collagen percentage assay of tumor tissues was significantly higher than that of background liver tissues [Sirius red group:(74.68 ± 1 1 .29)% vs (41 .59 ± 1 7.85 )%,P < 0.05;Masson group:(75.47 ± 1 1 .1 1 )% vs (40.41 ± 1 7.12 )%,P < 0.05 ].The SWV before operation was correlated positively to collagen percentage assay (Sirius red group:r =0.70,P <0.05;Masson group:r =0.73,P < 0.05 )of histological section after operation.Conclusions SWV value calculated by VTQ has reasonable correlation with collagen percentage assay of tumors,it is a valuable index for quantitative evaluation of the stiffness of liver cancer.
RESUMEN
Seventy two diabetic subjects type Ⅱ were given konjac food for 65 days.The data analysed by multiple F-test indicated that the fasting blood glucosc(FBG), 2-h postprandial blood glucose (PBG) at the 30th and 65th day after consuming the food were significantly reduced (P = 0.001, P200mg%) decreased on the average by 51.8 and 84.6 mg% respectively, those with FBG-O 150-200 mg% by 24.1 and 68.7mg%, and those with FBG-0200 mg%).It could be concluded that konjac food was very useful in both prevention and treatment of hyperglycemia.
