Objective To evaluate the value of CT perfusion imaging (CTPI) in the diagnosis of hepatocellular carcinoma (HCC). Method CTPI was carried out on 21 patients with 26 lesions to obtain the following perfusion parameters: hepatic blood flow (HBF), hepatic blood volume (HBV),mean transit time (MTT), permeability surface area product (PS), and hepatic arterial fraction (HAF). The parameters from the lesion and non-lesion areas were compared. In addition, serum AFP was measured in the HCC patients and a linear correlation analysis between the alpha-fetoprotein (AFP) level and the CTPI parameters was performed. Result CTPI failed in 3 patients with 3 lesions and was successful in 18 patients with 23 lesions which included 18 HCC, 4 hemangioma of the liver,and 1 hepatic focal nodular hyperplasia (FNH). On comparison of the HCC parameters in the lesion and non-lesion areas, significant differences were found in the HAF which was 4.11 times higher in the lesion than the non-lesion areas, while the MTT and PS were significantly lower. There was no significant difference in the HBF and HBV. Correlation between the serum AFP level and the CTPI parameters of the HCC lesion was insignificant. The differences of all the parameters between the lesion and the non-lesion in hemangioma were similar to those in HCC, except for a higher HBF in the lesion than in HCC. There was no significant difference between the parameters of FNH and the non-nodular part of the liver. Conclusion CTPI played an important role in the diagnosis and differential diagnosis of HCC, especially when the AFP was negative and/or the imaging manifestation was atypical on contrast CT.

Objective:To investigate the mechanism of increased glucose uptake, the expression of myoc ardial glucose transporter1 (GLUT1) was determined after low-flow myocardial is chemia. Methods: An in vivo open-chest canine model of low -flow myocardial ischemia was used to correlate myocardial glucose uptake with the number of GLUT1. The expression of myocardial GLUT1 glucose transporter was determined by semiquantitative Northern blotting and immunoblotting. Res ults: GLUT1 mRNA and GLUT1 polypeptide expression was substantially inc reased in ischemic region from the experimental hearts when compared to normal h earts. There was no significant regional difference in GLUT1 expression in eith er normal or ischemic hearts.Conclusion:Myocardial ischemia ind uces a factor or factors which stimulate GLUT1 expression in ischemic myocardial regions. Enhanced GLUT1 expression may be an important protective mechanism by which myocardial cells enhance glucose uptake and metabolism during low-flow my ocardial ischemia.

Objective: To investigate whether there is additi ve effects of hyperinsulinemia and ischemia on expression of canine myocardial G LUT4 gene in vivo. Methods: The expression of myocardial GLU T4 was determined by semiquantitative immunoblotting.The expression of GLUT4 mRN A was determined by semiquantitative Northern blotting. Results: Dramatic changes were seen in GLUT4 mRNA and GLUT4 expression in the ischemic hearts.After infusing insulin for 8 h,regional GLUT4 mRNA and GLUT4 levels in is chemic hearts were 2.5, 2.3-fold that of expression in normal hearts(P<0.01 ). Myocardial glucose uptake in ischemic hearts was increased by 4-fold when co mpared with normal hearts(P<0.01). Conclusion: There are not only additive effects of hyperinsulinemia and low-flow ischemia on canine myoc ardial GLUT4 mRNA and GLUT4 expression in vivo, but also increase of myocar dial glucose uptake. Enhanced GLUT4 expression may be an important protective m echanism by which myocardial cells enhance glucose uptake and metabolism during low-flow ischemia.

Objective To explore the relationship between heart rate variability (HRV) and deceleration capacity (DC) in children with idiopathic ventricular premature contraction of different origins. Methods The clinical data from 155 children with idiopathic ventricular premature contraction were retrospectively analyzed. According to the age, the children were divided into young children group (3 years old), preschool age group (3-6 years old) and school age group (6-16 years old). Each group was divided into the right ventricular type group and the left ventricular type group respectively according to the origin site. The differences of HRV and DC were compared among groups. Results Among three different age groups, the DC and time domain of HRV were signiifcantly different (P all?0 . 05 ). In young children group, RMSSD, HF, LF/HF, DC, and PNN 50 were statistically different between right ventricular type group and left ventricular type group (P all?0 . 05 ). In preschool age group, RMSSD, LF, HF, LF/HF, and DC were statistically different between right ventricular type group and left ventricular type group (P all?0 . 05 ). In school age group, the RMSSD, HF, LF/HF, and DC were statistically different between right ventricular type group and left ventricular type group (P all?0 . 05 ). Conclusions Children with idiopathic ventricular premature contraction have impaired regulations of cardiac autonomic system which mainly manifests as reduced tension of vagus nerve. Ventricular premature contraction originated from ventricle preponderance (young children and preschool children are right preponderance while school children are left preponderance) increases the risk of malignant arrhythmia.

OBJECTIVETo investigate whether insulin resistance exists in patients with colorectal cancer and its clinical significance.
METHODSA total of 135 patients with colorectal cancer were included as the study group, and 120 healthy subjects were included as the control group. Height, weight, and blood pressure were recorded. Fasting plasma glucose, triglycerides, high-density lipoprotein cholesterol (HDL-C), and insulin were measured. Insulin resistance index(lnHOMA-IR) was calculated.
RESULTSThe lnHOMA-IR was 0.84±0.38 in the study group and 0.42±0.08 in the control group(P<0.05). The incidence of metabolic syndrome was 34.1%(46/135) in the study group and 22.5%(27/120) in the control group(P<0.05). Insulin resistance index did not differ between the groups according to metabolic syndrome(0.98±0.41 vs. 0.74±0.22, P>0.05). There were no significant associations between insulin resistance index and tumor differentiation, depth of invasion, lymph node metastasis, distant metastasis, and TNM staging(P>0.05).
CONCLUSIONInsulin resistance exists in colorectal cancer patients, and it is possibly associated with metabolic syndrome and the tumor.

OBJECTIVETo analyze the clinical factors relating to arterial elastic function measured with pulse wave velocity (PWV), large and small arterial elastic indexes (C(1) and C(2)) and augmentation index (AI) in hypertensive patients.
METHODSA total of 2176 hypertensive patients were enrolled and divided into three groups: Elastic function was measured in 1100 subjects by (PWV), in 647 subjects by C(1) and C(2) and in 429 by AI.
RESULTSPWV was positively correlated with age, systolic pressure, pulse pressure and negatively correlated with body height and weights (all P < 0.05). C(1) and C(2) values were higher in male than that in female patients (P < 0.01) and negatively correlated with age, systolic pressure, pulse pressure and heart rate while positively correlated with body height, weight and body mass index. In hypercholesterolemia patients (n = 168), C(1) and C(2) were negatively correlated with serum cholesterol level (P < 0.05). AI value was higher in female than that in male patients (P < 0.01) and positively correlated with age, systolic pressure, diastolic pressure, pulse pressure while negatively correlated with body height, weight and heart rate.
CONCLUSIONAge, systolic and pulse pressure as well as body height and weights are the main factors correlated to arterial elastic function measured by PWV, C(1) and C(2) and AI.

OBJECTIVETo investigate the absorption and transport mechanism of magnolol in Caco-2 cell model.
METHODSA human intestinal epithelial cell model Caco-2 cell in vitro cultured was applied to study the absorption and transport of magnolol, the effects of time, donor concentration, P-gp inhibitor verapamil, pH and temperature on the absorption and transport of magnolol were investigated. The determination of magnolol was performed by high performance liquid chromatography, then the values of apparent permeability coefficient (P app ) and P ratio Basolateral-to-Apical (BL-to-AP)/Apical-to-Basolateral (AP-to-BL) were calculated.
RESULTSIn Caco-2 cell model, comparing the amounts of transport of AP-to-BL and BL-to-AP, the latter was larger. At the same donor concentration, either the amounts of transport of AP-to-BL or BL-to-AP increased with increase in donor concentration and incubation time. Verapamil could significantly improve the amounts of transport of AP-to-BL. The transport of AP-to-BL and BL-to-AP depended on temperature, and there was no significant effect of pH on the transport of AP-to-BL.
CONCLUSIONMagnolol could be transported through the intestinal mucosa via a passive diffusion mechanism primarily, coexisting with a carrier-mediated transport, at the same time, the efflux mechanism could be involved.
