To investigate the protective effect of L-carnitine on myocardial ischemia-reperfusion injury in rat heart,all harvested isolated hearts were perfused on Langendorff apparatus with oxygenized K-H solution for 20 min. The hearts were then exposed to ischemia for 30 min. Following the ischemia the hearts were re-perfused with K-H solution for 120 min to serve as the control group A. Either 5 or 10 mmol/L of L-carnitine was added into the K-H solution for 20 min at the beginning of reperfusion to generate group B and group C, respectively. The derivatives of the intraventricular pressure curve (DP/DT), left ventricular developed pressure (LVDP), and coronary flux were monitored during the entire experiment. The levels of ATP, hepatin, malondialdehyde (MDA), and superoxide dismutase (SOD) in tissue, and lactic dehydrogenase (LDH), creatine phosphate kinase (CPK), malondialdehyde (MDA), and superoxide dismutase (SOD) concentration in the coronary efflux were all measured. Compared with the control group, the treatment with L-carnitine resulted in better results, i. e., higher DP/DTmax and LVDP. At the same time, ventricular fibrillation was reduced, and the levels of ATP, hepatin and SOD were all elevated. However, the concentrations of MDA, CPK and LDH were all reduced. In conclusion, L-carnitine has a protective effect on ischemia-reperfusion injury, which is partly due to its prevention of energy loss and its antioxidant activity.

0.05).Conclusion The increase in the amount of nm23H1 protein expression can play an important role in restraining metastasis of squamous cell lung carcinoma.The heredity instability(MSI and LOH) of nm23H1 gene may not be implicated in expression of the gene and pathogenesis and progression of squamous cell lung carcinoma.

Objective:To study the effect of astrocyte elevated gene-1 (AEG-1) on proliferation and metastasis of papillary thyroid cancer (PTC) by regulating cell autophagy and epithelial-mesenchymal transition (EMT).Methods:Normal thyroid cells Nthy-ori3-1 and PTC cells TPC-1, FTC-133, B-CPAP and SW579 were cultured in vitro. Real time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of AEG-1 in PTC cells. The PTC cells with the highest AEG-1 expression were selected for AEG-1 shRNA infection, and then divided into sh-NC group and sh-AEG-1 group. Cell counting kit-8 (CCK8) and EdU (5-ethynyl-2 ′- deoxyuridine) experiments were used to detect the effect of AEG-1 on the proliferation of PTC cells; Transwell test was used to detect the effect of AEG-1 on the metastasis of PTC cells; subcutaneous tumorigenesis test in nude mice was used to detect the effect of AEG-1 on the expression of autophagy related proteins and EMT related proteins. PTC cells in sh-NC group and sh-AEG-1 group were treated with rapamycin and transforming growth factor-β (TGF-β), respectively. CCK8 and transwell assay were used to detect the cell proliferation and metastasis ability of each group of cells, respectively. Results:Compared with normal thyroid cells Nthy-ori3-1, the expression level of AEG-1 in PTC cells was increased, with the highest expression in TPC-1 cells. After AEG-1 shRNA was transfected into TPC-1 cells, cell proliferation, metastasis and tumorigenicity in vivo were reduced ( P<0.05). Compared with the sh-NC group, the expression of autophagy-related proteins P62 and Beclin1 were increased and the expression of LC3B protein was decreased, and EMT-related proteins E-cadherin expression were increased and N-cadherin and Vimentin protein expression were decreased in the sh-AEG-1 group ( P<0.05). CCK8 and Transwell experiments showed that treatment with autophagy inducer Rapamycin and EMT inducer TGF-β attenuated the inhibitory effect of sh-AEG-1 on proliferation and metastasis ability of PTC cell ( P<0.05). Conclusions:AEG-1 promotes the proliferation and metastasis of PTC cells by inducing cell autophagy and EMT.

OBJECTIVETo observe the effects of electroacupuncture (EA) at "Dazhui" (GV 14) on Wnt-β-catenin signal pathway in annulus fibrosus cells in intervertebral disc in rats with cervical spondylosis.

METHODSForty SD rats were randomized into a control group, a model group, an EA group and a medication group, 10 rats in each one. Rats in the control group were treated with sham operation, only incision on local skin; rats in the remaining groups were made into cervical spondylosis models. After model establishment, rats in the control group and model group received fixed treatment under identical condition; rats in the EA group were treated with EA at "Dazhui" (GV 14), 30 min per treatment; rats in the medication group were treated with intragastric administration of meloxicam tablets. Treatments were both given once a day, and 14 days were taken as one session; there was an interval of 2 days between two sessions, and totally two sessions were given. After the treatments, immunohistochemistry was applied to measure the expression of Wnt, glycogen synthase kinase-3β (GSK-3β) and Axin in annulus fibrosus cells; western blot was used to test the expression of P-β-catenin.

RESULTSIn the control group, there were more positive cells of Wnt, GSK-3β and Axin, which were intensively distributed, deeply colored, and strongly positive; In the model group, there were less positive cells of Wnt, GSK-3β and Axin, which were sparsely distributed and weakly positive. The expression of Wnt, GSK-3β, Axin and P-β-catenin in the model group was less than that in the control group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin in the EA group and medication group was higher than that in the model group (all P < 0.05); expression of Wnt, GSK-3β, Axin and P-β-catenin was not significantly different between EA group and medication group (all P > 0.05).

CONCLUSIONEA could delay the degeneration of intervertebral disc, which may be related to EA inhibiting signal pathway of Wnt-β-catenin.
