0.05).Conclusion MSCs could derive to cardiomyocyte-like cells after induction and incubation for 4 weeks in vitro,of which Ca~(2+)/CaMKⅡ is similar to the normal cardiomyocytes cells.

Objective To discuss the quantitative diagnosis of stagnation of Qi and blood stasis syndrome in chronic prostatitis. To make diagnosis chart and ensure diagnosis threshold level which provide statistics evidence for syndrome differentiation of TCM. Methods By the statistical ways, 168 cases of chronic prostatitis belong to stagnation of Qi blood and stasis syndrome and 198 cases of non-stagnation of Qi and blood stasis syndrome were investigated. To make a diagnosis chart and ensure diagnosis threshold level by applying the method of the maximum likelihood discriminatory analysis. Results The quantitative diagnosis chart was made and diagnosis threshold level was 26. According to the retrospective and prospective test, its sensitivity, especially degree, coincidence rate, error rate and positive likelihood ratio were 94.64%, 88.89%, 91.53%, 8.47%, 8.52 and 94.28%, 90.32%, 92.42%, 7.58%, 9.74. Conclusion The indexes of the quantitative diagnosis have good objectivity. According to the retrospective and prospective test, the diagnosis chart was proved to be practical.

Objective To explore the effect and safety of transcranial approach for spheno-orhital meningioma. Design Retro- spective case series. Participants Thirty-two patients being operated with transcranial approach. Twenty-four cases were meningothelial meningiomas, 3 cases were fibrous meningiomas, 1 case was psammomatous meningioma, 2 cases were atypital meningiomas, 2 case were malignant meningiomas. Methods All patients underwent frontal-temporal craniotomy, the involved sphenoid wing bone and peri- orbit were removed to prevent recurrence. The superior orbital fissure and optic canal were decompressed, the dural and periorbital de- feet were repaired by autogenous temporal fascia or artificial dura. Main Outcome Measures Preoperative and postoperative exoph- thalmus and eyeball movement, the extent of tumor resection, the ratio of recurrence. Results The extent of tumor resection: 8 cases were Simpson gradeⅡ, 20 cases Simpson gradeⅢ, 4 cases Simpson grade IV. After surgery, proptosis were improved in all patients, ophthalmoplegia was found in 6 eases. There was no operation-related death or other significant complication. Tumor recurred in 6 cas- es. Conclusions Adequate exposure of the tumor and bony decompression of the cranial nerves can result from transcranial approach, all the involved bone should be removed in order to prevent recurrence. This approach is relatively safe and the ptoptosis are improved significantly. Complete surgical resection is difficult because of the involvement of the orbital apex, superior orbital fissure and cav- ernous sinus.

Background and purpose:Chemotherapy plays an important role in the treatment of breast carcinoma by inhibiting the tumor growth and inducing the apoptosis.MAPK transduction pathway is closely related to proliferation and apoptosis of varieties of tumor cells,inhibition of MAPK pathway may increase the efficiency and decrease the toxicity of chemotherapy.Our study was to investigate the effect of MEK inhibitor PD98059 in response of breast cancer cell lines to Epirubicin.Methods:Human breast cancer cell lines MCF-7 and MCF-7/ADR were used as cell models.Epirubicin(EADM),PD98059(inhibitor of MAPK Kinase-MEK),or EADM+PD98059 was added into the culture medium,the expression of MEK2 and p-ERK were measured by Western blot,the growth of the two cell lines were measured by MTT.Results:ERK activity was elevated in MCF-7 after the treatment of EADM,the cells were more sensitive to EADM if combined with PD98059,while in MCF-7/ADR,ERK activity kept unchanged after EADM treatment,and PD98059 has no effect on the sensitivity of cells to EADM.Conclusion:MAPK signal transduction may be activated in some cells treated by EADM,adding inhibitor of MAPK signal transduction could improve the sensitivity of the cells to EADM.
