Objective To observe the changes of mononuclear cell (MNCs) apoptosis and the level of inflammatory cytokines and adhesion molecules in patients with systemic lupus erythematosus (SLE) and to study the relationship between them. Methods The apoptosis of MNCs in 22 patients with SLE at the active stage and 10 patients with SLE at remission and 10 healthy controls were determined with flow cytometry. The inflammatory cytokines and the adhesion molecules were tested with ELISA method. Results The percentage of MNCs apoptosis in the patients with SLE at the active stage was significantly lower than that of healthy con- trols and the patients with SLE at remission. There was no significance difference of MNCs apoptosis between healthy controls and patients with SLE at remission. The levels of IL- 8, TNF-?, IL- 6 , NO, P- sel and ICAM- 1 in patients with SLE at the active stage were significantly higher than that of healthy controls and the pa- tients with SLE at remission, and the increased levels of inflammatory cytokines and adhesion molecules in ac- tive SLE patients were negatively correlated to the percentage of MNCs apoptosis and positively correlated to the severity of SLE. Conclusion The data demonstrates that there is a promote apoptotic process of MNCs in active SLE. The high expression of inflammatory cytokines and adhesion molecules may play an important role of promoting MNCs apoptosis which reduces the functional life span of MNCs. For this reason, modulating the expression of cytokines and adhesion molecules and moderately controlling the apoptosis of MNCs may be a new therapeutic target for SLE treatment.

Aim To investigate the anti-tumor effects of FS-108 an Hsp90 inhibitor, on oncogene addicted EBC-1 and A375 cells. Methods SRB assay was performed to investigate cell proliferation. Immunoblot was conducted to investigate the specific proteins. FACS was conducted to test cell cycle distribution and apoptosis. Transwell assay was conducted to investigate cell motility. Results FS-108 significantly suppressed cell proliferation of EBC-1 and A375 cancer cells with IC50 at 25. 53 nmol · L-1 and 30. 02 nmol · L-1 re-spectively. FS-108 treatment triggered the degradation of key client proteins such as c-Met and B-Raf and thereby reduced their downstream AKT and ERK signa-ling pathways. The FACS analysis results demonstrated that FS-108 treatment induced G2/M phase arrest and apoptosis significantly. Furthermore, FS-108 inhibited the migration of EBC-1 and A375 cells. Conclusion As a potent Hsp90 inhibitor, FS-108 can inhibit onco-gene addicted cancer cells proliferation through induc-tion of G2/M phase arrest and apoptosis.

Objective To explore the correlation of the distance between anastomosis and dentate line in patients with severe circumferential prolapsed haemorrhoids treated by stapled haemorrhoidectomy with the patients' postoperative clinical manufestival score, and assess its value in the choice of anastomosis site in stapled haemorrhoidectomy. Methods One hundred and six patients with severe circumferential prolapsed haemorrhoids was treated by stapled haemorrhoidectomy. The distance between anastomosis and dentate line was documented during the operation, effect of the treatment and complications were also documented postoperatively. All above-mentioned data were analysed statisticaly by one-way ANOVA and ridit test.Results Four groups were established in 106 patients according to the distance between anastomosis and dentate line. Patients with distance less than 1.0cm were defined as group A, between 1.0 cm and 1.5 cm as group B, between 1.5 cm and 2.0 cm as group C, more than 2.0 cm as group D. Concerning the postoperative incontinence score, satisfaction index and complications such as haemorrhage,ederma of anal everage,residal skin-tags, there was no significant difference between all groups. But there was significant difference between four groups in score of pain. Conclusions Patients with severe circumferential prolapsed haemorrhoids treated by Stapled haemorrhoidectomy tend to have good clinical outcome. The appropriate distance between anastomosis and dentate line should be chosed by the status of prolapsed haemorrhoids.
