[Objective] To compare the biological characteristics of neuron-like cells from rat mesenchymal stem cells (MSC) induced by β-mercaptoethanol (BME) and basic fibroblast growth factor (bFGF) respectively. [Method] BME and bFGF were added to rat MSC respectively for 9 h and 5 days. The neuron-like cells from MSC with the neuron specific protein NF200 were identified using immunofluorescence. The gene expression of NF were analyzed using RT-PCR and the protein expression of NF200 were analyzed using Western blotting. [Results] MSC induced by BME appeared morphology change in an hour and the neurite can be seen at six hour. Some cell bodies became lighter and died. MSC induced by bFGF had neurite in the third day, and appeared network structure in the fifth day, then cells died in the seventh day. At the same time, The result of immunofluorescence showed the NF200 expression of neuon-like cells induced by two ways were beth positive, but MSC induced by bFGF were stronger than those induced by BME. The results of RT-PCR and western blotting were same as that of immunofluorescence. [Conclusion] Both bFGF and BME can induce rat MSC to neuron-like cells, but the neuon-like cells induced by bFGF were more like real neurons in morphology and expression of neuron specific protein and mRNA.

Objective To evaluate the effects of pyruvate Ringer' s solution on erythrocyte deformation function in the patients undergoing cardiopulmonary bypass (CPB) in vitro.Methods Thirteen patients of both sexes,aged 25-64 yr,of ASA physical status Ⅱ or Ⅲ (NAHY Ⅱ or Ⅲ),scheduled for elective cardiac valve replacement under CPB were enrolled in the study.At 10 and 60 min of CPB (T1,2) and 60 min after termination of CPB (T3),blood samples 18 ml were drawn from the radial artery and each patient's blood sample was equally divided into 6 parts (3 ml per part).The blood samples were divided into 3 groups (n =13 each):control group (group C),lactated Ringer's solution group (group R),and pyruvate Ringer's solution group (group P).In C,R and P groups,normal saline 1 ml,lactated Ringer's solution 1 ml,and pyruvate Ringer's solution 1 ml were added,respectively,and then the erythrocytes were incubated for 60 min at 37 ℃.At 30 and 60 min of incubation,the erythrocyte rigidity index (ERI) and erythrocyte deformation index (EDI) were detected.Results Compared with C and R groups,the ERI was significantly decreased at 30 and 60 min of incubation at T1,the EDI was decreased at 30 min of incubation at T1,2,and no significant change was found in ERI at T2,3 or in EDI at T3 in group P.There was no significant difference in ERI and EDI at different time points of incubation within groups.Conclusion Pyruvate Ringer's solution can enhance erythrocyte deformation function in the patients undergoing CPB.

Objective To explore the association of expression of apoptosis-associated gene BAK and cFLIP with the biological behaviors in endometriosis. Methods The expression of BAK and cFLIP protein gene in eutopic and ectopic tissue samples from 40 cases with pathologically confirmed ovarian endometriosis and 40 cases with pathologically confirmed normal endometrium was detected by immunohistochemical method. Results ①The expression of BAK and cFLIP protein gene was found in three groups of different endometrial tissue. ②The expression of BAK protein gene was increased gradually in ectopic endometrial , eutopic endometrium and normal tissue and there was significantly difference between every two groups ,while cFLIP was contrary expressed (P <0.05); ③In normal endometrium, The expression of BAK protein gene in secretory phase was higher than that in proliferative phase (P < 0.05), while cFLIP was contrary expressed, in eutopic endometrium and ectopic endometrial tissue , The expression of BAK and cFLIP protein gene in secretive phase showed no statistically significant difierence with that in proliferative phase (P > 0.05). ④The expression of BAK protein gene in severe group (Ⅲ-Ⅳ period) is lower than mild group both in eutopic or ectopic endometrial tissues,while cFLIP was contrary expressed (P < 0.05). ⑤The expression of BAK and cFLIP was negatively correlated with each other in ectopic endometrium (r=-0.389,P< 0.05). Conclusion BAK and cFLIP was negatively expressed in EMS, which may take a part in the endometrial apoptosis and disorderly proliferation. BAK and cFLIP may play an important role in the the diagnosis and treatment of endometriosis.
