Long non-coding RNAs (lncRNAs)are closely related to the tumorigenesis,proliferation, metastasis and clinical outcome,whihc play important roles in the process of drug resistance of many tumor cells.Recently,research indicates that many lncRNAs regulate drug resistance of tumor cells through a variety of signaling pathways both in vitro and in vivo.Furthermore,it is also found that after blocking the relevant tar-gets can reverse this chemoresistance.

Objective To explore the treatment method and clinical effect of LARS artificial ligament in treatment of combined anterior cruciate ligament(ACL) and posterior crueiate ligament (PCL) injuries of the knee under arthroscope. Methods Thirteen cases of ACL and PCL injuries were reconstructed with LARS ligament. The patients were followed up for 12-36 months. The International Knee Documentation Committee (IKDC) and Lysholm knee score scale were used for functional evaluation. In the meantime, KT-1000 was employed to check anterior and posterior laxation of the knee. Results No knee infection or limitation of knee extension occurred. Knee flexion was 105° -125° (average 117°). At termination of follow up, 10 cases (77%) was graded as A and 3 (23%) as B according to IKDC. KT-1000 examination at 25° flexion showed that the difference of anterior laxation was less than 2 mm in 12 cases and 3-5mm in 1. KT-1000 examination at 70°flexion showed that the difference of anterior laxation was less than 2mm in 12 cases and 2-4 mm in 1. The Lysholm score was (63.8±2.9) points (49459 points) before operation and (91.1 ±2.7) points (88-95 points) at follow up, with statistical difference (P ＜0.01). Conclusion Reconstruction of ACL and PCL by using LARS ligament under arthroscope is a kind of minimally invasive, safe and effective method to treat ACL and PCL injuries of the knee, with good short term outcome.

Apoptin,a chicken anemia virus-derived protein.selectively induces apoptosis in trans-formed or tumor cells but not in normal cells.The tumor specificity of apoptin is thought to be related to its cel-lular localization.The apoptin-induced apoptosis is p53-independent and can not be blocked by overexpressionof Bcl-2.But activation of Caspase-3 is essential for apoptin-induced apoptosis.These features make apoptin a potential candidate as a novel therapeutic and diagnostic tool in cancer treatment.

BACKGROUND:In anoxic environment, invasive ability of tumor cels significantly increased. The increase in above invasive ability is possibly associated with the changes in urokinase or matrix metaloproteinases. Studies on hypoxia and tumor therapy especialy the effect on chemotherapy have made great progress, and found that hypoxia-inducible factor 1 is a key nuclear factor mediating celular hypoxia response, and also an important factor for regulating cel apoptosis during hypoxia. OBJECTIVE:To observe the effects of cyclooxygenase-2 inhibitor NS-398 on invasive ability of MG-63 cels under hypoxic condition in cel models of hypoxia osteosarcoma. METHODS: Chemical hypoxia inducer cobalt chloride was used to establish chemical hypoxia environment of concentration gradient of 0, 100, 200, 400 μmol/L. Under 200 μmol/L cobalt chloride, concentration gradient of 30, 60, 90 μmol/L of NS-398 were set. Osteosarcoma cels were determined after 48 hours of culture. Quantitative PCR was used to detect the expression of matrix metaloproteinases 9 mRNA and hypoxia-inducible factor 1α mRNA. Western blot assay was applied to measure hypoxia-inducible factor 1α expression. Flow cytometry was utilized to examine cel apoptosis in each group. RESULTS AND CONCLUSION:PCR and western blot assay results demonstrated that with increased concentration of cobalt chloride, matrix metaloproteinases 9 mRNA and hypoxia-inducible factor 1α mRNA and protein expression increased (P < 0.05), showing a concentration-dependent manner. Under cobalt chloride concentration of 200 μmol/L and hypoxia, with increased concentration of NS-398, matrix metaloproteinases 9 mRNA and hypoxia-inducible factor 1α mRNA and protein expression gradualy reduced, showing a concentration-dependent manner (P < 0.05). Flow cytometry results showed that under 400 μmol/L cobalt chloride concentration, cel apoptosis noticeably reduced. Under cobalt chloride concentration of 200 μmol/L and hypoxia, with increased concentration of NS-398, cel apoptosis increased (P < 0.05). Results confirm that anaerobic environment is an important factor for increased invasive ability of osteosarcoma. Under the anaerobic environment, NS-398 could effectively suppress the invasive ability of osteosarcoma and promote cel apoptosis.
