Purpose To investigate the relationship and clinical significance of high-risk human papillomavirus infection and expression of c-jun and c-fos protein in cervical carcinoma.Methods Cervista HR-HPV testing,immunohistochemical SP method were employed to detect the infection of HR-HPV,c-jun and c-fos protein in 70 cases of CSCC,60 cases of cervical intraepithelial neoplasia and 20 cases of chronic cervicitis.The correlation between c-jun and c-fos protein expression and of HR-HPV infection was analyzed.Results Of the 70 cases of CSCC,the positive HR-HPV was 69 cases,the positive rate in HR-HPV in A9 group was the highest (85％,59/69).The positive expression of c-jun and c-fos were 80％ (56/70),85.7％ (60/70) in 70 cases CSCC,70％ (21/30) and 70％ (21/30) in 30 cases of cervical high grade intraepithelial neoplasia,and 20％ (6/30),23.3％ (7/30) in 30 cases cervical low grade intraepithelial neoplasia,but the positive expression rates of c-jun and c-fos in the 20 cases of chronic cervicitis were 0.Expression of c-jun and c-fos in cervical cancer group was higher than that in the chronic cervicitis group and low grade intraepithelial neoplasia (P ＜ 0.05).The expression of c-jun and c-fos was statistically significant in different groups of clinical stage and pathologic grading in the CSCC (P ＜ 0.05).Additionally,the expression of c-jun and c-fos was positively correlated with the infection of HR-HPV in CSCC (P ＜ 0.01).Conclusion The infection of HR-HPV has significant subtype-specific and has a positive correlation with the expression of c-jun and c-fos in CSCC,which suggests that AP-1 pathway activation after HRHPV infection may be associated with the occurrence and development of cervical carcinoma.

Objective To evaluate the effect of dezocine on the c-fos expression in neurons in the midbrain periaqueductal gray in a rat model of incisional pain.Methods Thirty-six pathogen-free healthy adult male Wistar rats,weighing 250-300 g,were divided into 3 groups (n =12 each) using a random number table:control group (group C),incisional pain group (group I) and dezocine group (group D).A 1 cm longitudinal incision was made through skin,fascia and muscle of the plantar aspect of the right hind paw in sevoflurane-anesthetized rats.In group C,the rats were only anesthetized and underwent no operation.In group I,0.9％ sodium chloride solution 2 ml was injected via the caudal vein at 15 min before the model was established.In group D,dezocine 1 mg/kg (diluted to 2 ml in 0.9％ sodium chloride solution) was injected via the caudal vein at 15 min before the model was established.At 24 h before operation (T0) and 2,6 and 24 h after operation (T1-3),the mechanical paw withdrawal threshold (MWT) and cumulative pain score were measured.After measurement of the pain threshold at T3,the whole brain was removed for determination of the c-fos expression in neurons in the midbrain periaqueductal gray by immunohistochemistry.Results Compared with group C,the MWT was significantly decreased,cumulative pain scores were increased,and the expression of c-fos in neurons in the midbrain periaqueductal gray was upregulated at T1-3 in I and D groups (P＜0.05).Compared with group I,the MWT was significantly increased,the cumulative pain score was decreased,and the expression of c-fos protein in neurons in the midbrain periaqueductal gray was down-regulated at T1.3 in group D (P＜0.05).Conclusion Dezocine mitigates incisional pain through inhibiting the expression of c-fos in neurons in the midbrain periaqueductal gray of rats.

Objective To investigate the genotype distribution of extended-spectrum?-lactamases(ESBLs) and AmpC?-lacta- mases produced by Escherichia coli and Klebsiella pneumoniae in 10 teaching hospitals of China.Methods 90 clinical strains of E.coli and 61 strains of K.pneumoniae isolated in 2003 and confirmed to produce ESBLs were collected from 10 teaching hos- pitals in China.Analytical isoelectric focusing was used to measure the pI of the?-lactamases.Conjugation experiment was used to study the transfer of cefoxitin resistance.Plasmid-mediated AmpC enzyme genes were amplified and sequenced by multiplex polymerase chain reaction (MPCR).Results The prevalence of ESBL-producing E.coli and K.pneumoniae was about 50% in Wuhan,Nanjing and Jinan.The prevalence of ESBL-producing E.coli was lower than K.pneumoniae in Beijing.However,in other hospitals the prevalence of ESBL-producing E.coli was a little higher than K.pneumoniae.About 24.4% of ESBL-pro- ducing E.coli isolates and 19.4% of ESBL-producing K.pneumoniae isolates were resistant to cefoxitin.Cefoxitin-resistant i solate was identified in all hospitals except Shenyang.Major genotype of ESBL-producing isolates was CTX-M.The CTX-M-9 group was the most common group,followed by CTX-M-1.More K.pneumoniae isolates produced both ESBLs and AmpC en- zyme than E.coli.The genotype was CTX-M/DHA-1.The PCR results of 3 transconjugants producing both ESBLs and AmpC enzyme were the same as their donor isolates.Conclusions The genotype of ESBL-producing isolates is mainly CTX-M-9 group in these teaching hospitals.More K.pneumoniae isolates produced both ESBLs and AmpC enzyme than E.coli.Most of these isolates are due to geno type CTX-M/DHA-1,which can spread through plasmid.

Two fragments G1 and G2 of the glycoprotein G gene of bovine respiratory syncytial virus(BRSV) were selected for expression in Escherichia coli based on the analysis of glycoprotein G by DNA Star software.Then the two fragments of glycoprotein G were amplified by PCR with synthesized G gene of BRSV as the template.The amplified fragments G1 and G2 are 570bp and 308bp in length,respectively.The PCR products were cloned into pET30a vector and expressed in soluble form in E.coli after induction of cultured E.coli with IPTG.Both of the recombinant proteins G1 and G2 were purified by immobilized Ni ion affinity chromatography under native conditions.Then the purified proteins were analysed by Western blotting.The results showed that the purified recombinant protein G1 retained good antigenicity and specificity.But the purified recombinant protein G2 didn't possess biological activity.Antibodies against BRSV were detected in suspected bovine serum samples in China by using indirect ELISA and Western blotting with the purified recombinant protein G1.The purified recombinant protein G1 might be used as antigen for establishing serological methods for diagnosis of BRSV infection.And the purified recombinant protein G1 might also be used for preparing polyclonal and monoclonal antibodies for research on biological functions of glycoprotein G of BRSV.
