Chinese Pharmacological Bulletin 1986;0(04):-
Aim To study tumor suppressor gene OPCML,DAPK methylation changes during the process of CasKi cell apoptosis induced by trichosanthin, and to explore the correlation and the role between cervical cancer cell apoptosis and tumor suppressor gene methylation so as to find new demethylation drugs.Methods ① MTT was applied to assay the inhibition of TCS to CasKi cell proliferation and flow cytometry was used to analyze cervical CasKi cell apoptosis induced by trichosanthin; ② Methylation-specific PCR(MSP) technology was applied to detect cervical cancer and during cell apoptosis process OPCML and DAPK gene promoter methylation status of CpG islands.Results In CasKi cervical cancer cells,OPCML and DAPK gene promoter region showed a high degree of CpG island methylation status, by trichosanthin treatment,the growth of CasKi markedly was inhibited, and flow cytometry analysed the characteristic sub-G1 peak,OPCML and DAPK gene promoter region showed no CpG island methylation of performance.Conclusions During the process of CasKi cell apoptosis induced by trichosanthin,OPCML and DAPK gene demethylated significantly,accordingly, trichosanthin might be a new methylation inhibitor,and there might be some correlation between cell apoptosis and tumor suppressor gene methylation.And OPCML and DAPK gene methylation tests might become new clinical indicators for the early detection of cervical cancer.
2.The update research advances on survivin
Cancer Research and Clinic 2006;0(11):-
Studies on survivin over the past several years have shown it has significant association with cancer, its encoding protein play a important role in control of mitosis and/or apoptosis and the activity of cellullar immunologic response in cancer patients. Survivin is the finding of its splice variants make it more valuble. The multi-subcellular localization of survivin is consistent with its multiple functions in cellular metabolisms and responses. The mechanisms and the subcellular localization by which these splice variants differentially affect cancer development are unclear. This review article will update the role of survivin, and its splice variants in the mitosis/cell cycle, apoptosis, tumorigenesis, chemoprevention, drug/radiation resistance, and cancer therapeutics.

Objective To discuss the techniques and efficacy of arthroscopy-assisted treatment for popliteal cyst. Methods From June 2004 to January 2006, 14 patients with popliteal cyst were diagnosed and treated with arthroscopy. During the operation, the popliteal cyst was removed, and then the hernial opening was repaired by suturing the medial head of the gastrocnemius tendon. The outcomes of the operation were evaluated by using Rauschning and Lindgren Grading. Results Arthroscopic examinations showed evident pathological changes in the knee joints of the 14 patients, including 6 cases of posterior horn medial meniscus tear, 1 case of chondromalacia of patella, 2 patellofemoral malalignment, 4 osteoarthritis, and 1 discoid lateral meniscal tear. The patients were followed up for 5-18 months (mean 11 months). According to the Rauschning and Lindgren Grading, 8 patients were grade Ⅱ and 6 were grade Ⅲ before the operation. After the operation, 9 patients were grade 0, 4 were grade Ⅰ, and 1 was grade Ⅱ. There was a significant difference between the pre-and postoperative grading (Z=-4.498, P=0.000). No patient had recurrence during the follow-up. Conclusions Popliteal cyst is usually induced by knee joint disorders. It was difficult to eliminate the cyst by simple resection. Arthroscopy-assisted treatment can achieve good outcomes.
