AIM: To observe whether metallothionein plays a role in cardiac protective effect of basic fibroblast growth factor on anoxic/reperfusion (A/R) injury in cultured cardiomyocytes and study the possible mechanism of cardiac protection by bFGF.METHODS: The present study made the model of myocyte A/R injury after having a 24 h incubation by bFGF( 10-10、10-9、10-s mol/L) and bFGF( 10-9 mol/L) + PD098059 respectively. We measured the levels of MT and MDA in myocytes, and the changes of LDH and protein in cultured medium. We also counted the number of viable cell in groups. RESULTS: The contents of myocardial MT were significantly increased after treatment by bFGF. The levels of MT in I0-l0 mol/L、10-9 mol/L and 10-8 mol/L bFGF treated groups increased 54 %、 62%、 76% respectively, compared with the A/R group, and the number of viable cell were also greatly increased, LDH and protein leakage in cultured medium and MDA contents in myocyte were dramatically decreased in bFGF treated groups. All the protection were completely disappeared with the inhibition of MT production with PD098059, theinhibitor of mitogen- activated protein kinase(MAPK). CONCLUSION: MT involves in the protection of bFGF in cultured cardiomyocytes. It might be related with activation of MAPKase.

OBJECTIVE To explore risk factors of cervical lymph node metastasis in cN0 papillary thyroid carcinoma. METHODS The clinical data of 537 patients with cN0 papillary thyroid carcinoma were analyzed retrospectively in Beijing Tongren hospital from Jan 2009 to Dec 2015. Patients' gender, age, multifocal lesion, carcinoma complicated with Hashimoto's thyroiditis, capsule breakthrough and tumor size were counted. RESULTS The lymph node metastasis rate of 537 patients with cN0 papillary thyroid carcinoma was 30.9%(166/537). The incidences of lymph node involvement were 24.95%(166/537) at only level VI, 5.21%(28/537) at level VI plus lateral part of neck and 0.74%(4/537) at only skip metastasis, respectively. Chi square test and multivariate logistic regression analysis showed that cervical lymph node metastasis was statistically associated with male, age<45 years, capsule breakthrough and tumor diameter>1 cm (P<0.05). After the operation, there were 17 patients with temporary hoarseness, accompanied with 1 loss to follow-up and 1 failure to return to normal after 1.5 years. There were 61 patients with temporary hypocalcemia, 2 patients failed to follow-up and 2 patients with calcium supplements after respective 1.5 and 4 years. CONCLUSION To stratify the risk of patients with cN0 papillary thyroid carcinoma, male, age<45 years, capsule breakthrough and tumor diameter>1 cm are risk factors for cervical lymph node metastasis. And we suggest that prophylactic central lymph node dissection may be appropriate.

Objective To explore the diagnostic value of delayed 18 F?FDG PET/CT pelvic imaging after forced diuresis in detecting male patients with locally recurrent rectal cancer. Methods Thirty?two male patients ( 32-79 years) with clinically suspicious recurrences of rectal cancer were retrospectively ana?lyzed. All patients underwent a standard 18 F?FDG PET/CT followed by a delayed pelvic imaging after 2.5 h of administration of 20 mg furosemide intravenously and extra water intake of 500 ml at least. Final diagnosis was made by pathology or clinical follow?up (>10 months ) . Diagnostic efficiency of 18 F?FDG PET/CT standard and delayed pelvic images were calculated and compared. χ2 test was used for data analysis. Re?sults A total of 25 patients were diagnosed with recurrent rectal cancer, including 10 cases with invasion of surrounding tissue, and 5 cases with metastases. Among the 7 patients without local recurrences, 2 had dis?tant metastases. The sensitivity, specificity, and accuracy of standard FDG PET/CT were 92.0%(23/25), 3/7, 81.2%(26/32), respectively. The corresponding values of the delayed imaging were 96.0%(24/25), 6/7, and 93.8%(30/32), respectively. The specificity of delayed imaging was higher than that of standard FDG PET/CT (χ2=14.333, P<0.05) , but no significant differences were found in sensitivity and accuracy between the delalyed imaging and standard FDG PET/CT (χ2=0.085 and 0.966, both P>0.05) . The urina?ry bladder activity reached or approached the background during the delayed imaging. Twenty?two malignant lesions of surrounding invasion were confirmed. The positive rate of delayed imaging was higher than that of standard FDG PET/CT:95.5%(21/22) vs 63.6%(14/22);χ2=6.400, P<0.05. Conclusions 18F?FDG PET/CT delayed pelvic imaging after diuresis and hydration is useful for eliminating the artifacts from urina?ry bladder activity, and for detecting the invasion to the rectal surrounding tissue more effectively. It could be a supplement to standard FDG PET/CT.

OBJECTIVE To study the antitumor activity and underlying mechanisms of Xiaoaiping injection(Xap)combined with gefitinib(Gef)in nude mice bearing resistant non-small cell lung cancer (NSCLC) cells H460 or H975. METHODS BALB/c nude mice were inoculated with human NSLCL cells H460 or H1975 and the drug treatment did not start until the tumor volume reached 50-100 mm3. The tumor bearing mice were divided into four groups:control group,Xap group(5 g · kg-1,ip),Gef group (50 mg · kg-1,ig),and Xap plus Gef group. All the administration lasted for 21 d continuous. Tumor volumes were measured two or three times per week,and the body weight of animals was re-corded. At the end of the test,tumors were weighed after the sacrifice of mice. Tumor inhibition rate and relative tumor proliferation rate were calculated based on tumor weight and tumor volume. The related biomarkers and proteins in tumor tissues were detected by immunohistochemistry and Western blot assay, respectively. RESULTS Compared with the control group,no significant effect was observed on the growth of H460 and H1975 xenografts in groups of Xap or Gef alone in nude mice. However,the two-drug combination significantly suppressed tumor volume,with (1103 ± 340) versus (3020 ± 450) mm3 for H460 and(487 ± 153)versus(1269 ± 161)mm3 for H1975,respectively(P<0.05). The combined Xap and Gef application also significantly reduced the tumor weight,with(1.20±0.52)versus(2.78± 0.93)g for H460 and(0.52 ± 0.32)versus(0.92 ± 0.42)g for H1975,respectively(P<0.05). The relative tumor proliferation rate and inhibition rate in the combination group was 42.1%and 43.5%for H460(P<0.01),43.0%and 52.5% for H1975(P<0.01). Compared with Xap and Gef drug alone,their combination showed significant difference in reducing tumor weight,suppressing tumor proliferation rate and increasing tumor inhibition rate(P<0.05). Immunohistochemistry results showed that each drug alone had no effect on tumor angiogenesis markers of vascular endothelial growth factor(VEGF)and CD105 expression,or on drug resistance related proteins of p-ERK,p-Akt and p-mTOR,whereas the combination of Xap and Gef obviously reduced the expression of these biomarkers in H460 and H1975 tumor tissues. The decreased drug resistance related proteins of p-PI3K and its downstream molecules p-Akt,p-ERK and p-mTOR by the two-drug combination were also confirmed by Western blot results(P<0.01,compared with control), and showed significant difference compared with each single treatment(P<0.05). CONCLUSION The addition of Xap significantly improves the antitumor activity of Gef in H460 and H1975 xenografts,and this synergistic effect may be ascribed to the inhibition of tumor angiogenesis,the down-regulation of PI3K and its downstream signaling molecules which are associated with drug resistance.
