Objective To investigate the expression of KLF4 in cervical carcinoma and its significance. Methods Immunohistochemistry and tissue microarray were used to examine the expression of KLF4 in 39 cases of carcinoma, 30 cases of normal cervical epithelial tissues and 28 cases of cervical cancer in situ. Results Moderate to strong nuclear staining for KLF4 was found in normal tissues and cervical cancer in situ. Interestingly, KLF4 expression was lost in 16 (P<0.05) of 39 carcinoma cases. However, KLF4 expression was not associated with clinicopathologic parameters, including tumor stage and differentiation. Conclusion Our observations indicate that KLF4 may function as a tumor suppressor in the pathogenesis of cervical cancer.

Objective To investigate the effects of paravertebral injection of different concentrations of adriamycin on motor conduction function in rats. Methods Eighty healthy male Wistar rats weighing 250-300 gwere randomly divided into 4 groups (n = 20 each): 3 adriamycin groups receiving paravertebral injection of 0.3%, 0.5% and 1.0% adriamycin 10 μl respectively (group A1, A2, A3) and control group (group C)receiving equal volume of normal saline (NS) instead of adriamycin. The animals were anesthetized with intraperitoneal 3% pentobarbital 40 mg/kg. A right paramedian incision was made in the back from L3 to S1.L4,5,5,6 intervertebral foramina were exposed. 0.3%, 0.5% and 1.0% adriamycin and NS 10 pl were injected into the intervertebral foramina in group A1, A2, A3 and C respectively. Spinal motor evoked pontential (SMEP)was measured at 1, 2, 4 and 8 weeks (T1-4)after paravertebral injection. Results The latent period of SMEP was significantly prolonged and the amplitude decreased at T1-4 in group A3 as compared with group A1, A2 and C.Conclusion Paravertebral injection of 1.0% adriamycin can significantly depress motor conduction function.
