Objective: To study the protective effect of baicalin on myocardial ischemia reperfusion injury and its correlation to myocardial cell autophagy in experimental rats. Methods: The animal models were established by intragastric infusion at 7 days prior operation in different groups.Atotal of 48 rats were divided into 4 groups: Sham operation group, Sham+baicalin group, Ischemia reperfusion (IR) group and Baicalin treatment group. n=12 in each group. Hemodynamics at different time points and myocardial infarction (MI) size at 45 min after reperfusion were recorded; protein expressions of LC3-II and autophagy-related Becl-1 at 30 min after reperfusion were examined by Westernblot analysis; the opening condition of mitochondrial membrane channel transition pore (mPTP) was detected by NAD+ content. Results: The MI sizes in Sham operation group and Sham+baicalin group were too small to compare; MI sizes in IR group and Baicalin treatment group were (41.32±1.85) % vs (23.30±1.60) %, P<0.001. Protein expressions of LC3-II in IR group and Baicalin treatment group were (1.051±0.005) and (0.863±0.009) which were both higher than Sham operation group (0.763±0.007), P<0.01;Becl-1 were (1.169±0.002) and (0.943±0.005) which were both higher than Sham operation group (0.647±0.014),P<0.01; LC3-II and in Becl-1 expressions in Baicalin treatment group were decreased than IR group, P<0.01. NAD+ contents (by nmol/mg) in IR group and Baicalin treatment group were (6.02±0.33) and (9.56±0.53) which were both lower than Sham operation group (11.28±0.37), P<0.001; NAD+ content in Baicalin treatment group was increased than IR group,P<0.01. Conclusion: Baicalin had no autophagy effect in normal myocardial cells, but it may decrease the MI size and reduce excessive autophagy in myocardial cells after IR which might be related to inhibiting mPTP opening.

Objective:To investigate the influence of hepatocyte growth factor(HGF)on the expression of vascular endothelial growth factor C(VEGF-C)and the mechanism of HGF-induced VEGF-C expression in tongue squamous cell carcinoma Tca8113 cells.Methods:Tca8113 cells were cultured and exposed to HGF with various concentrations.The expression level of VEGF-C was assessed by ELISA.Signaling transduction inhibitors LY294002,U0126,SP600125,SB203580 was used to block PI3K/Akt,P44 /P22MAPK,JNK,P38MAPK signaling pathways,respectively.Then,the expression level of VEGF-C was detected by ELISA.Re-sults:The VEGF-C expression of Tca8113 cells increased at the beginning and decreased later with the increase of HGF concentra-tion.When the concentration of HGF was 40 ng/ml,VEGF-C expression level was the highest.Inhibitor LY294002 of PI3K/Akt and Inhibitor U0126 of P44 /P22MAPK significantly blocked the effects on HGF-induced VEGF-C up-regulation(P <0.01 ).Inhibitor SP600125 of JNK and inhibitor SB203580 of P38MAPK didn't interfere HGF-induced VEGF-C expression(P >0.05).Conclusion:HGF contributed to the expression of VEGF-C,PI3K/Akt and P44 /P22MAPK signaling pathways may be involved in HGF-induced VEGF-C up-regulation,and may play potential roles in lymphatic metastasis of oral squamous cell carcinoma.

Objective To explore the characteristic of SPECT/CT imaging of osteolytic lesions with increased bone metabolism and its correlation with CT manifestation. Methods Twenty?one cancer patients with bone metastases underwent 99 Tcm?MDP SPECT/CT imaging ( 13 males, 8 females; age: ( 60. 52 ± 6?85) years) were retrospectively studied. The imaging characteristic of the lesion with high uptake of 99Tcm?MDP was observed and the correlation between the lesion/background ( L/B ) ratio and CT manifestation were analyzed. One?way analysis of variance, two?sample t test and linear correlation analysis were used. Results A total of 111 lesions were found in 21 patients by 99 Tcm?MDP whole?body bone scan, and 125 le?sions were found by SPECT/CT imaging, including 111 lesions with increased bone metabolism and abnor?mal CT manifestation and 14 osteolytic lesions with decreased bone metabolism. In 111 lesions with in?creased bone metabolism, there were 23(20.72%) osteolytic lesions, 54 (48.65%) osteoblastic lesions and 34 (30.63%) mixed lesions. The L/B ratio of osteolytic lesions with increased bone metabolism (11.82± 6?61) was lower than that of osteoblastic lesions (20.03±13.24) and that of mixed lesions (25.42±19.51;F=6.00, P<0?05) . The CT value of osteolytic lesions with increased bone metabolism was higher than that of osteolytic lesions with decreased bone metabolism :(167.53±79.21) HU vs (88.63±49.16) HU; t=3?345, P<0.05. The L/B ratio of lesions with increased bone metabolism was positively correlated to CT val?ue(r=0.404, P<0?05). Conclusions A part of lesions with increased bone metabolism on SPECT/CT im?ages are osteolytic lesions. The L/B ratio of them is positively correlated to CT value. SPECT/CT imaging can reduce missed diagnosis and misdiagnosis.

Objective To explore the significance of 18fluorodeoxyglucose positron emission tomography(18F?FDG PET/CT)in the etiological diag?nosis of postoperative intestinal obstruction in patients with gastrointestinal cancer. Methods A total of 51 patients with postoperative intestinal ob?struction undergone 18F?FDG PET/CT were enrolled for the study. The images were interpreted by visual and semi?quantitative analysis(maximum standard uptake value,SUVmax). All the cases were confirmed by pathology and clinical follow?up for more than half a year. The sensitivity,specifici?ty and accuracy of 18F?FDG PET/CT for detecting malignant intestinal obstruction were calculated. Results Of the 51 patients,35 cases were con?firmed for malignant intestinal obstruction,and 16 cases were caused by other benign diseases. 18F?FDG PET/CT imaging was positive in 36 cases, and 33 cases were diagnosed as malignant and recurrent intestinal obstruction. Three cases of PET false?positive were peritonitis adhesion and anasto?motic inflammation. Two cases of PET false negative were peritoneal micrometastasis. The SUVmax of malignant lesions was 8.86±4.82,and the SUVmax of benign lesions was 2.05±1.95. The uptake of FDG was significantly higher in malignant intestinal obstruction than in benign intestinal obstruction (t=7.15,P<0.01). The sensitivity,specificity,and accuracy of 18F?FDG PET/CT diagnosis of malignant lesion were 94.3%,81.3%,and 90.2%, respectively. Conclusion The uptake of 18F?FDG in malignant intestinal obstruction was higher than that in benign intestinal obstruction. 18F?FDG PET/CT have a good diagnostic value for the intestinal obstruction of postoperative gastrointestinal cancer.

Background and purpose:The proportion of incidental thyroid cancer in PET imaging was sig-niifcantly increased with the wide application of18F-FDG PET/CT. The correlation between the glucose metabolism of thyroid incidental thyroid cancer and pathological changes is unclear. The objective of this study is to analyze the relationship between the glucose metabolism by18F-FDG PET/CT and tumor differentiation or lymph node metastasis in patients with incidental thyroid cancer.Methods:A total of 195 patients with focal FDG-avid thyroid incidentaloma during cancer evaluation were enrolled. Fifty-three patients were diagnosed as having thyroid cancer by the pathology. The SUVmax of thyroid cancer foci, lesion size, lesion number, and SUVmax of normal thyroid tissue were quantiifed. The tumor pathological grades and lymph node metastasis were analyzed by the pathology. The patients were broken down into 4 groups (G1, G2, G3 and G4) according to the tumor pathological grades and lymph node metastasis (differentiated thyroid cancer, non-differentiated thyroid cancer, without lymph node metastasis and with lymph node metastasis). The differences of glucose metabolism between G1and G2groups, G3 and G4 groups were analyzed.Results:Fifty-three foci were found by PET imaging. Sixty-two foci were found by the pathology (37 papillary thyroid carcinoma, 4 follicular thyroid carcinoma, 9 medullary thyroid carcinoma, 3 poorly differentiated thyroid cancer). The SUVmax in the normal thyroid tissue, G1and G2were 1.51±0.30, 4.25±1.70 and 6.34±2.45, respectively. The SUVmax in the G1and G2were signiifcantly higher than in the normal thyroid tissue (t=11.0,t=7.10,P<0.01). The SUVmax of G3was 4.77±2.15, and the SUVmax of G4group was 4.67±2.02. The differences between G1and G2groups, G3 and G4groups were not statisti-cally signiifcant (t=3.61,P>0.05;t=0.33,P=0.56).Conclusion:The differentiated incidental thyroid carcinoma and non-differentiated incidental thyroid carcinoma had high glucose metabolism, and there was no signiifcant difference in the levels of glucose metabolism in different differentiation degree and metastasis ability cancer.
