ABSTRACT

Objective To explore the differences and similarities of the cervical lesions and mechanism between Asian variant E6 T178G and European variant E6 T350G, A442C and other variants. Methods We selected 300 clinic or hospitalized patients in our hospital during the period of May 2011 to October 2012. Cervical exfoliated cells were harvested by Thinprep cytologic test (TCT). A PCR sequencing assay was performed to detect HPV16 E2, E6 and E7 gene variants. One year later, the test was repeated. The patients with persistent infection underwent cervical biopsy by colposcopy for pathological examination. SP immunohistochemical method was applied to detect E7 protein expression level in all the patients. Results After one year, of 292 patients who were successfully sequenced, 259 were chronic cervicitis, 32 were cervical intraepithelial neoplasia grade I (CINI), and one was cervical intraepithelial neoplasia grade II (CINII). E7 protein expressed in each variant. But the expression of E7 protein in patients with different variant infection had no significant difference from each other. Conclusions E7 protein may be play a role in the early stages of HPV16?induced cervical lesions. But E7 protein may not be a reference index of the different carcinogenic mechanism between different HPV16 variants.

ABSTRACT

<p><b>OBJECTIVE</b>To study the effect of the Chinese compound prescription Chaihu Shugan Tang (CHSGT) on the excitability in the cerebral cortex and hippocampus (different brain regions) of pentetrazole (PTZ)-kindled chronic epileptic rats.</p><p><b>METHOD</b>To establish the model of chronic kindling rats intraperitoneal injected with pentylenetet. Fully kindled rats were randomized into control and experimental groups for intragastric administration of normal saline (control, model), Sodium Valproate and CHSGT at the high, medium and low doses for 4 consecutive weeks. The content of 2-NBDG, the glutamate (Glu) and the aspartate (Asp) in different brain regions of rats were detected by fluorescence imaging techniques and HPLC assay respectively.</p><p><b>RESULT</b>CHSGT at the high, medium and low doses all significantly decreased the content of 2-NBDG, the Glu and the Asp in different brain regions of chronic epileptic rats (P < 0.01).</p><p><b>CONCLUSION</b>CHSGT can inhibit the excitability in different brain regions of PTZ-induced epileptic rats, by decreasing the level of excitatory neurotransmitter maybe one of its antiepileptic mechanisms.</p>

ABSTRACT

OBJECTIVE:To investigate the impact of the drug price limits policy on the consumption of anti-infectives in our hospital.METHODS:The consumption sum and DDDs of the chief categories of anti-infectives in our hospital before and after the adoption of drug price limits policy(between Oct.,2004 and Sept.,2005 and between Oct.,2005 and Sept.,2006)were analyzed statistically.RESULTS & CONCLUSION:Both DDDs and consumption sum of the chief categories of anti-infectives in our hospital decreased markedly since the adoption of drug price limits policy.
