Based on the anatomic data and fractal theory, the vascular tree model of forearms similar to actual vessel was established, and then the 3D heat transfer model of forearms based on the actual vessel anatomic structure was created. The model was analyzed and investigated with finite element method to explore the influential factors such as dimensional distribution of vessel, blood perfusion rate and external heat source for the 3D temperature field. The simulation results were consistent with the experimental data derived from Pennes. The model well reflects the regional difference of tissue temperature caused by the irregular distribution of vessel, and provides temperature guidance for tumor thermotherapy.

Objective To construct Hepatitis B Virus (HBV) Chinese-strain wild type and Lamivudine-resistant variant recombinant baculovirus. Methods 1.2-unit length HBV construct (adr serotype, C genotype) was cloned into the multiple cloning region of the pFastBac Ⅰ vector and then transformed into DH10Bac, in which homologous recombination occurred between the pFastBac vector and the inside bacmid with the help of helper plasmid. So HBV recombinant bacmid was produced and transfected into sf9 cells to generate a Recombinant HBV baculovirus called vAcHBVc. The viral titers were detected by immune plaque assay and TCID 50. Lamivudine resistance mutation (YVDD) was introduced by site-directed mutagenesis using continuous PCR. HBV YVDD recombinant baculovirus (vAcHBVcYVDD) was generated and titered as above. Meanwhile, the recombinant HBV baculovirus containing GFP reporter was constructed for evaluating the efficacy of transfection and titration of virus. Results Recombinant wild and YMDD variant HBV baculovirus were successfully developed and the titer was between 10~6～10~8pfu/ml through plaque assay. Conclusion Different kinds of recombinant HBV baculovirus could be generated rapidly and efficiently with Bac to Bac expression system. The developed recombinant HBV baculovirus could be further used in the study of anti-viral resistances.

Objective To investigate the relation ship between the changes of platelet parameters and intracranial hemorrhage in premature children with low birth weight. Methods 73 premature children with low birth weight were selected as research subjects and divided into PIVH group (35 cases) and non PIVH group (38 cases) according to intracranial hemorrhage or not,and 20 normal newborns were selected as controls. The neonatal platelet parameters of three groups were detected and compared. Results There were 35 cases of 73 premature children with low birth weight occurred intracranial hemorrhage, the incidence rate was 47. 9%. The gestational age and birth weight of PTVH group were (29.3 ± 1.2) weeks and (1 653.0 ± 182. 1) g and which were significantly lower than the non PIVH group( all P ＜0.05) ; the asphyxia rate of PIVH group was 60.0% and which was significantly higher than the non PIVH group(P＜0.05). The PLT and PCT of PIVH group were (187.52 ±52.03) × 109/L and (0.127 ± 0.05) % and which were significantly lower than the control group (all P ＜ 0. 05) ; The PLT and PCT of non PIVH group were(223.48 ±42.15) × 109/L and (0. 189 ±0. 06)% and which were significantly lower than the control group(all P＜0. 05) ; The PLT and PCT of PIVH group were significantly lower than the non PIVH group(all P ＜ 0.05) ; while the MPV and PDW among the three groups had no significant difference ( all P ＞ 0. 05 ). Conclusion The abnormal decrease of PLT and PCT should be involved in the pathogenesis of intracranial hemorrhage in premature children with low birth weight, clinical attention should be paid to the monitoring of platelet parameters in premature children so as to alert and minimize its incidence.

Objective To investigate the effects of short term insulin pump intensive therapy on flow-mediated dilation (FMD) in type 2 diabetes mellitus (T2DM) patients with and without vascular complications. Methods Seventy-six patients with T2DM (T2DM group) were divided into 2 subgroups: T2DM1 subgroup (28 patients with vascular complications) and T2DM2 subgroup (48 patients without vascular complications). Meanwhile, 30 healthy cases were selected as NC group. All research subjects accepted high-frequency ultrasound detection on brachial artery for FMD. After insulin pump intensive therapy,FMD in T2DM group was reexamined, fasting insulin was detected and HOMA-IR was calculated. Results Compared with that in NC group, FMD in T2DM group was significantly lower(P＜ 0.01). However, glycosylated hemoglobin (HbA1c ), fasting plasma glucose (FPG ),H0MA-IR and blood fat were significantly higher (P＜0.01 or ＜0.05). Correlation analysis showed that FMD had negative correlation with HbA1c, FPG, HOMA-IR, triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C)(P＜0.01),and had positive correlation with high-density lipoprotein cholesterol (HDL-C). After 2 weeks of insulin pump therapy, the improvement of FMD between the two groups was different. FMD in T2DM1 subgroup increased from (4.25 ± 1.96)% to (4.96 ± 1.36)%(P＞0.05), and FMD in T2DM2 subgroup increased from (4.02 ± 2.35)% to (7.56 ± 2.34)%(P＜ 0.01). Conclusion Insulin pump intensive therapy can evidently improve FMD in T2DM patients without vascular complications.

Nitric oxide (NO) plays an important pathophysiological role in osteoarthritis and cartilage metabolism. To determine the relationship between NO and the synthesis of type II collagen in cartilage, we measured levels of type II collagen by ELISA and procollagen (II) mRNA by RT-PCR in cultured lapine chondrocytes that were incubated with some kinds of reagents. 0.2mM sodium nitroprusside (SNP, a NO donor) can release high levels of NO, decreasing type II collagen, suppressing the expression of procollagen (II) mRNA (COL2A1).At the same time, chondrocytes showed a large increase in NO synthesis, a decrease in type II collagen and COL2A1 mRNA in response to 100u/ml IL-1. When 1mg/ml N-nitro-L-arginine methyl easter (NAME, an inhibitor of NO synthase) was mixed with IL-1, NO production was inhibited, the amounts of type II collagen recovered partially and COL2A1 mRNA recovered completely.These data indicate NO can inhibit type II collagen synthesis as IL-1 downstream molecule by suppressing procollagen (II) mRNA.

To analyze the relationship among ambulatory blood pressure (AMBP), ankle brachial index (ABI) and left ventricular mass index (LVMI) in hypertensive patients. Methods 578 hypertensive inpatients were reviewed. Results The general clinical dataof selected patients, their ABI, LVMI were not different significantly between male and female. The correlation analysis showed that LVMI was positively correlated with the 24-hour average systolic (r=0.245, P=0.000) or diastolic (r=0.158, P=0.000) blood pressure, whereas negatively correlated with percent of systolic (r=－0.104, P=0.012) or diastolic (r=－0.132, P=0.001) blood pressure declining at night. No significant correlation was found between LVMI and BMI. Multiple regression analysis revealed that LVMI was significant independently positive correlated with 24-hour average systolic blood pressure (P=0.000). Conclusion LVMI does not correlate with ABI, but independent positive related with 24-hour average systolic blood pressure.
