Objective To explore if keratinocytes that stably maintain HPV11 genome can be obtained by transfection and selection methods. Methods Escherichia coil containing pBR322.HPV11 plasmid was cultured and amplified. Then the plasmid was extracted, purified and digested with BamH Ⅰ enzyme to release viral genome from the bacterial vector. After recovering from the low-melting point agarose gel by electrophoresis, the genome was self-circulated with T4 DNA ligase. The religated DNA was cotransfected with pTK-neo DNA into HaCaT keratinocytes using Lipofectamine reagent. After selection with G418 for 2 to 3 weeks, clonal and pooled cultures were expanded and analyzed. Fluorescent quantitative PCR (FQ-PCR) and nested reverse transcriptase PCR (nRT-PCR) were applied to detect HPV11 DNA and spliced HPV11 E1^E4 mRNA expression in the transfected cells. Results After the cotransfection of HPV11 genome into HaCaT keratinocytes and two-week selection,G418-resistant cell colonies were obtained with morphological features indistinguishable from normal HaCaT keratinocytes. As shown by FQ-PCR, HPV11 DNA was present in G418-selected HaCaT keratinocytes. The average viral DNA load capacity was 15.9±16.8 copies/cell in the primary culture of G418-selected HaCaT cells and 23.9±1.1 copies/cell in the third passage of the cells; there was no statistical difference between the two passages of cells (t=-0.822, P>0.05). nRT-PCR targeting HPV11 E1^E4 mRNA transcript produced a specific 628-bp fragment, which was shown by agarose gel electrophoresis. Conclusions Our data indicate that HPV11 genome can be successfully introduced into HaCaT keratinocytes by transfection and HPV11 DNA-positive cells can be obtained by G418 selection. Moreover, HPV11 DNA is still present in the third passage of transfected cells.

Objective To evaluate the role of spinal extracellular signal-regulated kinase (ERK) signaling pathway in reduction of remifentanil-induced hyperalgesia by electro-acupuncture (EA) at Zusanli in rats with incisional pain.Methods Fifty male adult Sprague-Dawley rats, weighing 250-280 g, in which the intrathecal catheter was successfully placed without complications, were randomly divided into 5 groups (n=10 each) using a random number table: control group (group C), remifentanil + incisional pain group (group RI), EA at acupoint group (group E) , EA at non-acupoint group (group NE), and 1/2 ERK inhibitor U0126 + EA at acupoint group (group UE).Normal saline 0.1 ml · kg-1 · min-1 was infused intravenously for 60 min in group C.In RI, E, NE and UE groups, after the model of incisional pain was established, remifentanil 1.0 μg · kg-1 · min-1 was infused for 60 min, and in addition, EA (intensity 10 mA, frequency 4 Hz) of Zusanli lasting for 60 min was performed at the same time in E and UE groups, and EA was performed at the points 5 mm lateral to the acupoints of Zusanli on the operated side simultaneously in group NE.ERK1/2 inhibitor U0126 5 μg (in 5％ dimethyl sulfoxide 10 μl) was injected intrathecally in group UE, and 5％ dimethyl sulfoxide 10 μl was injected intrathecally in the other groups.The mechanical paw withdrawal threshold (MWT) was measured before remifentanil or normal saline infusion (T1) , and at 2 h, 1, and 2 days after the end of infusion (T2-4).After MWT was measured at T4, the expression of ERK1/2 and phosphorylated ERK1/2 (p-ERK1/2) in spinal cord dorsal horns was measured by Western blot.Results Compared with group C, the MWT was significantly decreased at T2-4 in RI, E, NE and UE groups, and the expression of p-ERK1/2 was up-regulated in RI, E and NE groups (P＜0.05).Compared with group RI, the MWT was significantly increased at T2-4 , and the expression of p-ERK1/2 was down-regulated in E and UE groups (P＜0.05);and no significant change was found in the parameters mentioned above in group NE (P＞0.05).Compared with group E, the MWT was significantly increased at T2-4, and the expression of p-ERK 1/2 was down-regulated in group UE (P＜0.05).Conclusion The mechaism by which EA at Zusanli reduces hyperalgesia induced by remifentanil in rats with incisional pain is related to inhibited activation of ERK signaling pathway in the spinal cord.
