Objective To explore the relationship between expressions of C-type lectin receptors on natural killer(NK) cells and infant human cytomegalovirus (HCMV) infection. Methods Seventynine cases of HCMV infection infants and 39 cases of HCMV non-infection control infants admitted during January 2006 to June 2008 were recruited in this study. According to HCMV pp65 antigenemia levels in the peripheral blood, 79 cases of HCMV infection infants were divided into two groups: 48cases of active HCMV infection and 31 cases of inactive HCMV infection. The 48 cases of infants with active HCMV infection were treated with ganciclovir for 2 weeks. The expressions of NKG2A,NKG2C, and NKG2D receptors on NK cells in the peripheral blood were examined by flow cytometry.Data analysis was done using SPSS 17.0 software. Comparisons among 3 groups were performed by Kruskal-Wallis nonparametric test for independent samples and comparisons between groups were done by Mann-Whiteney nonparametric test for paired samples. Results There was no difference of the inhibitory receptor NKG2A expression on NK cells among groups of active HCMV infection, inactive HCMV infection and HCMV non-infection controls (x2 = 3. 95, P＞0. 05). However, there was obvious difference of activating receptors of NKG2C and NKG2D expressions on NK cells among the three groups (x2 =24.91 and x2 =47. 80, respectively; both P＜0.01). The expressions of NKG2C and NKG2D on NK cells in the HCMV infection group were both higher than the control group (Z=-4.72 and Z=-5.15, respectively; both P＜0.01). The expression of NKG2D on NK cells in the active HCMV infection group was higher than that in the inactive HCMV infection group (Z= -5.08,P＜0.01). The expression of NKG2D on NK cells decreased after ganciclovir treatment (Z= - 1.34,P=0. 07). Conclusion Expressions of NKG2C and NKG2D on NK cells might play a significant role in regulating NK cell function and anti-HCMV immunity in infants.

Objective To explore the influence of candesartan (an angiotensin II receptor 1 antagonist,AT1R) in radioresistance of human nasopharyngeal carcinoma CNE1 cells.Methods Cell growth of CNE1 with or without candesartan treatment was measured in vitro by MTT method;radiosensitivity of CNE1 with or without candesartan treatment was tested under normoxic or hypoxic conditions by clone formation assay.The expression of hypoxia-induced factor 1α(HIF-1α)in CNE1 cells was analysed by western blotting.Results Candesartan did not significantly inhibit the growth of CNE 1 cells in both normoxic and hypoxic conditions.Candesartan also did not influence the radiosensitivity of CNE1 cells in normoxic condition;however,it significantly increased the radiosensitivity of CNE1 cells in hypoxic condition.The expression of hypoxia-induced factor 1 α (HIF-1 α)in hypoxic CNE1 cells was significantly inhibited by candesartan treatment.Conclusion Candesartan does not significantly influence the proliferation of CNE1 cells in both normoxic and bypoxic conditions but significantly enhances the radiosensitivity of hypoxic CNE1 cells,in which the mechanisn may be involved in its inhibiting HIF1α expression in hypoxic CNE1 cells.

Objective To develop an accurate,rapid,high throughout genotyping method based on oligonucleotide microarray for cytochrome P450 gene polymorphisms related to paclitaxel metabolism.Methods The mutant points of 2C8 * 3,3A4 * 18 and 3A5 * 3C from cytochrome P450 gene were regarded as targets.Based on the sequences in the GenBank,the wild-type and mutant-type probes were specially designed for each mutant point.PCR primers were located in the both sides of mutant point,and furthermore the fragments of PCR products were less than 200 bp.Each type of standard plasmids was constructed.Thus,all the olignucleotide probes were modified with 3'amino-group,and the reverse primers were labeled with fluorescein (Cy3).The probes were immobilized onto certain glass slides.The specific fragments of three genes were amplified and then hybridized with oligonucleotide microarray.The results were analyzed by using certain software.Finally this assay was applied to detect 50 clinical blood specimens.Results When PCR products from standard plasmids were hybridized with DNA microarray,the corresponding probes produced positive signals.Meanwhile,the non-specific hybridization signals did not appear.The results of clinical specimens showed that the mutant rate of CYP2C8 * 3 was 2%.The point of CYP3A4 * 18 for all the clinical specimens was wild-type and the mutant rate of CYP3A5 * 3C was 62%. Meanwhile,the results from detecting 50 clinical blood specimens using oligonucleotide microarray were the same as sequencing analysis.Conclusions Oligonucleotide microarray is a reliable and accurate genotyping assay for cytochrome P450 2C8 * 3.3A4 * 18 and 3A5 * 3C polymorphisms related to paclitaxel simultaneously.This genotyping assay is a high-throughout method for guiding personalized therapy and analyzing metabolism of paclitaxel in vivo.

Objective To investigate the prevalence of physical state of HPV-l6 DNA in cervical cancer and cervical precancerous carcinoma. Methods Multiplex PCR was adopted to detect the physical state of HPV in samples from 252 patients with cervical carcinoma, including 48 samples of cervical cancer, 204 cervical intraepithelial neoplasia (CIN ) (125 CIN I, 46 CIN II and 33 CIN III) and 20 normal samples from the subjects with hysteromyoma undergoing hysterectomy, respectively. Results Among 48 patients with cervical cancer, 31 (65.6%) were infected with HPV-16. Eighteen among 31 (58.1%) HPV-16 infected patients with cervical cancer were found to have integrated infection of HPV-16. The positive rates of HPV-16 infection in the patients with CIN I, CIN II and CIN III were 19.2%, 34.8%and 42.4%, and the integrated infection rates of HPV-16 were 16.7%, 18.8%and 35.7%, respectively. Compared with patients with different grades of CIN, the integrated rate of HPV-16 infection in those with cervical cancer was significantly elevated. Conclusion Among the patients with HPV-16 infection, the integrated state of HPV-16 is positively correlated with the severity of cervical lesions. Combined HPV typing test and detection of integrated viral state contribute to predicting the prognosis of patients with cervical precancerous lesions and increasing the accuracy of screening cervical cancer on the basis of HPV DNA detection.
