Abstract: Objective　To construct a mouse model of Schistosoma japonicum liver disease induced by direct injection of Schistosoma japonicum eggs through the portal vein and evaluate its effectiveness, in order to provide a new animal model for schistosomiasis liver disease research. Methods　Fifteen 8-week-old C57BL/6 male mice were randomly divided into control group and egg injection group, with 5 in the control group and 10 in the egg injection group. On day -14, 5 000 live eggs were injected into the abdominal cavity of mice, and on day 0, the mice were anesthetized and the abdominal cavity was opened. 5 000 live eggs were injected through the portal vein, and the control group was injected with equal volume of phosphate buffer (PBS). 5 mice in the egg group were killed on day 10 and 30, respectively. The control group mice were killed on day 10, and their serum and liver tissue were collected. Hematoxylin eosin staining (HE) and Masson staining were performed, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), and liver hydroxyproline (HYP) content were detected using a microplate spectrophotometer. Liver fibrosis-related genes, Th1 and Th2 type immune response-related genes were analyzed by real-time fluorescence quantitative PCR (qPCR). Liver injury, egg granuloma and fibrosis, and adaptive immune response were detected to evaluate the effect of portal vein injection of eggs while inducing mouse model of schistosomiasis liver disease. Results　The results showed that significant egg granulomas appeared in the liver of mice after injection of eggs into the portal vein for 10 and 30 days. There was no statistically significant difference in the area of egg granulomas between the 10-day group and the 30-day group (t=0.975, P=0.332). Masson staining and liver hydroxyproline content detection showed significant fibrosis in the liver. The qPCR results showed that, compared with the control group, the expression levels of fibrosis marker genes, such as α⁃Sma (alpha smooth muscle actin), Col1a1 (collagen type Ⅰ alpha 1), and Tgfb1 (transforming growth factor beta 1), were significantly increased (t=6.380, 7.533, 5.314; P=0.002, 0.001, 0.007), and then decreased on the 30th day, with no statistical difference compared to the control group (t=0.940, 1.529, 1.746; P=0.778, 0.543, 0.457). At the same time, the expression levels of Th1 type immune response-related genes, such as tumor necrosis factor alpha (Tnf), interferon gamma (Ifng), and Th2 type immune response-related genes, such as interleukin-5 (Il5), interleukin-13 (Il13), significantly increased 10 days after eggs injection (t=6.163, 4.589, 5.651, 5.367; P=0.003, 0.018, 0.020, 0.009). In addition, there was no significant change in the levels of AST and ALT in the serum of each group of mice (t=0.982, 3.450; P=0.771, 0.074. t=1.164, 0.564; P=0.697, 0.917). Conclusions　A mouse model of schistosomiasis liver disease induced by portal vein injection of worm eggs was constructed. The study provides a new modeling method for studying the mechanism of liver fibrosis in schistosomiasis..

Objective To evaluate the therapeutic effect of intramyocardial controlled releasing base fibroblast growth factor (b-FGF) stent combined with transplanting bone marrow-derived mesenchymal stem cells (BM-MSCs) in porcine acute myocardial infarction (AMI) models. Methods Eighteen porcines were divided into three groups (each n=6):transmyocardial revascularization (TMR)+naked stent (control group), TMR+b-FGF stent (b-FGF group) and TMR+b-FGF stent+BM-MSCs (b-FGF+BM-MSCs group). Acute myocardial infarction models were induced by ligating the left anterior descending artery in 18 porcine. In the control and b-FGF group, naked stents, b-FGF stents and b-FGF stent+BM-MSCs were implanted into TMR channels in the infarct and border zone. ~(99m)Tc-methoxyisobutylisonitrile (MIBI) myocardial perfusion imaging were performed to evaluate changes in myocardial blood flow, and echocardiography and immunohistochemical studies were also performed. Results After 6 weeks, the quality of myocardial infarction, fractional shortening, neovascular density in b-FGF and b-FGF stent+BM-MSCs group were higher than those of control gruop (P<0.05), and in b-FGF stent+BM-MSCs group was higher than those in b-FGF group (P<0.05). Conclusion BM-MSCs combined with controlled releasing intramyocardial b-FGF stent can improve the flow of myocardial infarction area, promote angiogenesis and heart function, and the therapeutic effect which can be evaluated with myocardial SPECT imaging.

Objective To investigate the effects of intestinal ischemia-reperfusion(I/R)on cerebral microglial activation in rats.Methods One hundred and twenty-eight healthy male SD rats weighing 250-300 g were randomly allocated to one of two groups(n =64 each):group sham operation(group S)and intestinal I/R group.Intestinal I/R was produced by occlusion of superior mesenteric stery for 90 main followed by reperfusion.Sixteen animals were sacrificed at each of the 4 time points:2,6,24 and 48 h of reperfusion in each group.Their intestines were obtained for microscopic examination.Their brains were harvested for detection of microglial activation (by immuno-histochemistry).The reactive oxygen species(ROS),MDA and NO contents and SOD,nitric oxide synthase(NOS)and inducible nitric oxide synthase(iNOS)activities in the brain were measured.Results The microglia were in quiescent condition.Ibal staining was negative or light in group S.Intestinal I/R significantly increased intestinal Chiu score,cerebral microglial activation at 6,24 and 48 h of repeffusion which peaked at 24 h of reperfusion in group I/R as compared with group S.Cerebral ROS,MDA,NO levels and NOS,iNOS activities were significantly higher while SOD activity was significantly lower in group I/R than in group S.Concluslon Intestinal I/R can activate microglia and induce the release of nitrogen and oxygen free radicals resulting in cerebral injury.

Objective To evaluate the impact of sarpogrelate on the in-stent restenosis (ISR) after percutaneous transluminal angioplasty (PTA) in peripheral arterial diseases (PAD).Methods PAD patients who had PTA for the first time were divided into two groups receiving respectively clopidogrel and aspirin (clopidogrel group) or sarpogrelate and aspirin (sarpogrelate group).Vascular ultrasonography was performed at 6 months after PTA in all patients to evaluate the degree of ISR.Results 62 patients finished the follow-up visits as required.The in-stent restenosis in the sarpogrelate group and clopidogrel group was 7.0％ vs.18.1％ (P =0.036),the peak systolic velocity ratio was 1.34 vs.2.08 (P =0.010) and the cases of ISR was 1 vs.10 (P =0.005) respectively.No patients reported serious adverse events.Conclusions Sarpogrelate combined with aspirin is safe and effective.Compare with clopidogrel and aspirin,sarpogrelate and aspirin can significantly reduce the rate of ISR after PTA and the intimal proliferation in the stent.
