RESULTS: After differentiation of human adherent myoblasts by neural induction medium, no cells with a neural cell morphology (ie., small, refractile cell body with dendritic cell extensions) were seen. All remaining myoblasts cultured with neural induction medium, myoblasts with proliferation medium and myotubes with differentiation medium containing 20 mL/L HS were positive for β Tubulin Ⅲ. C2C12 myoblasts were negative for β Tubulin Ⅲ. In contrast, all the above cells were negative for the markers Neurofilament Mr 68×103 and GFAP.

Transcriptional activity of ACL recombinants normalized by Renilla was significant difference with pGL3-Basic expect for construct -27 and -15 (P＜0.01). Construct -919 contains highest activity. 3 times reduction of transcriptional activity from-919 to -679bp indicated that negative regulation factors located probably in this region. The activity started on construct -73 suggested the basal promoter activity was located within the -73 to +77bp region; Transcriptional activity of IDHβrecombinants was not significantly different between the recombinant -58 and pGL3-Basic. The activity started on construct -82, decreasing with the length of the fragment up to -164 in despite of a bit of fluctuation, and kept increasing from construct -164 up to -279. Thus, the basal promoter activity was located within the -82 to +16bp region, whereas the upstream 197bp conferred maximal transcriptional activity.

采用5'端缺失策略，结合启动子预测结果，分别构建了8个ACL基因和19个IDH3β基因启动子区重组子，将其转染猪PK15细胞系，并利用荧光素酶双报告基因系统检测了它们的活性，结果表明：在所构建的猪ACL基因5侧翼序列的8个重组子中，除pGL-ACL27和pGL-ACL15外，其它重组子的荧光素酶活性与阴性对照均达到极显著水平(P＜0.01)，表明它们均具有启动子活性，pGL-ACL919活性最强，到pGL-ACL679活性下降了将近3倍，说明从-919bp到-679bp区域可能存在负的调控位点，从pGL-ACL621到pGL-ACL73活性有小幅度下降，到pGL-ACL27活性降到与阴性对照水平无显著差异，表明维持该启动子的基本活性区域位于-73bp到+77bp之间；IDH3β基因启动子活性开始于pGL-IB82，然后虽然有些波动，但是活性一直下降直到-164bp处，之后活性又开始升高，直到-279bp处活性达到最高，这些表明维持该启动子的基本活性区域位于-82bp到+16bp之间，从-82到-279之间的179bp区域具有最高的启动子活性。

Anti-MOG and anti-MBP antibodies predicted more frequent and earlier relapses. Of 39 seronegative patients, nine (23%) had a relapse, and time to relapse was 45 13.7 months. Of 22 patients with anti-MOG and anti-MBP, 21 (95%) relapsed, and mean time to relapse was 7.5 4.4 months. Of 42 patients with only anti-MOG, 35 (83%) relapsed within 14.6 9.6 months P .001 for both comparisons with antibody-seronegative patients.

研究显示，抗MOG和抗MBP抗体可以预测更多和更早期的发作，39名血清呈阴性的患者中，9位(23%)复发，而重新发作的时间是45 ± 3.7个月，22名带有抗MOG和抗MBP的患者中，21名(95%)复发，复发时间为 7.5 ± 4.4个月，另外42名患者只有抗MOG，35人(83%)在 14.6 ± 9.6个月之内复发（P 。001，二组相较于血清呈阴性的患者）。
