Objective To establish a method to detect viral integrity of human papillomavirus in women cervical HPV infection. Methods We amplified E6/E7 gene and E2 gene of HPV16,then inserted them into a plasmid containing single copy HBB gene. HPV16 infected cervical epithelium samples were screened out by genotyping with RDB of flow-through hybridization assay.Fluo-rescence quantitive PCR data of HBB,viral E2 gene and viral E6 gene of all samples were standardized by compared with respective parameters of the plasmid.The ratio IHPV and CHPV were calculated to find out E2 gene disruption and viral copies per cell in the cer-vical samples,respectively.Results The plasmid constructed for standardization was proved effective to make the FQ-PCR data of E2 gene,E6 gene and HBB gene comparable.Thirty-seven HPV16 positive cervical epithelium samples included 22 cases from women whose TCT were normal,and 15 cases from women who confirmed HIL/CIN 2-3 or above through colposcopic examina-tion plus biopsy.Fifteen samples were detected E2 gene disruption,including 10 HIL/CIN 2-3 or above samples and 5 TCT normal samples.E2 gene integrity in different groups were statistically significant different(P <0.05).The average viral copies per cell dis-played a significant decline along with E2 gene disruption(P <0.05).Conclusion The tandem single copy gene plasmid standard-ized methord for the detection of E2 gene disruption caused by viral integration in HPV16 infected cervical cells is feasible and effec-tive.

Objective To explore the association between three SNPs of IL 10 promoter and childhood systemic lupus erythematosus (SLE).Methods Three SNPs( 1082/ 819/ 592) were genotypes,and evidence for linkage disequilibrium was analyzed using Genehunter 2 0 software.The correlations between symptoms and haplotypes were assessed.Results The results showed that all genotypes and haplotypes in the IL 10 promoter region exhibited to significant association with childhood SLE,and no significant differences in clinical features among childhood SLE with various haplotypes could be demonstrated.But the frequence of haplotype GCC ( 1082 *G 819 *C 592 *C) in children with SLE and their parents was higher than that in adult SLE patients and adult normal controls,and the frequence of ATA in children with SLE was lower than that of adult SLE patients.Conclusion It is concluded that haplotype GCC might have certain relationship with childhood SLE,which deserves further study.

Objective To investigate clinical efficacy and side effects of long-acting risperidone microsphere injection for treatment of patients with schizophrenia. Methods A total of 82 patients with schizophrenia were randomly divided into two groups,study group with long-acting risperidone microsphere injection and control group with atypical antipsychotics treatment for 24 weeks. The Positive and Negative Syndrome Scale (PANSS),The Personal and Social Performance (PSP) and Treatment Emergent Symptoms Scale (TESS) were used to evaluate efficacy and adverse effects of treatment at the end of 1st ,2nd,4th, 12nd and 24th week. Results The therapeutic efficacy in control group was similar to that in study group,and there was no significant difference between the two groups (P＞ 0.05 ). But the therapeutic efficacy in study group was better than that in control group at the end of the 4nd week (P＜0.05 ) , and study group was more likely to improve social function(P ＜ 0. 05 ). Incidence of adverse effects in study group was lower than that in control group , but the difference was not significant (P ＞0.05 ). The incidence of akathisia symptom in study group was higher than that in control group,but the difference was not significant (P＞0.05). The incidence of drowsiness symptom in study group was significantly lower than that in control group(P＜0.05 ). Conclusion Long-acting risperidone microsphere injection is as effective as atypical antipsychotics for treatment of patients with schizophrenia, but it has better efficacy in improving social function of the schizophrenia with lower side effects.

Objective To explore the influence of three SNPs within interlukinc (IL) 10 promoter region on the expression of interlukin 10 mRNA in childhood systemic lupus erythematosus (SLE),then to determine if the SNPs do associate with the pathogenesis of childhood SLE.Methods The levels of IL 10 mRNA were detected in children with SLE and their parents by Taqman PCR,then the correlations between levels of IL 10 mRNA and haplotypes were assessed.Results The results showed that haplotype GCC was associated with higher level of IL 10 mRNA within children with SLE.Conclusion Haplotype GCC is associated with high secretion of IL 10 within childhood SLE,but not operate independently,and maybe it regulates the high secretion of IL 10 with other susceptible genes of SLE.

Objective To investigate the effect of RBP on 3T3-L1 adipocyte differentiation,lipid metabolism and glucose transporter 4(GLUT-4)gene expression.Methods We constructed an expression vector for rat resistin gene and transfected it into 3T3-L1 adipocytes.RBP was added to the medium of 3T3-L1 adipocytes or resistin-overexpressing adipocytes on day 0 of differentiation.Cell differentiation and lipid accumulation were determined by oil red O staining.The mRNA expressions of differentiation marker genes(pref-1,C/EBP?,FAS)and GLUT-4 gene were evaluated by RT-PCR.Triglyceride(TG)and free fatty acids(FFAs)in adipocytes were measured by colorimetric kit.Results(1)When 10-12mol/L RBP was applied,the percent of living cells was high and the shape was unchanged.(2)RBP had no effect on the differentiation of normal adipocytes,but significantly decreased the number of lipid droplets in resistin-overexpressing adipocytes without affecting the lipid droplets-presenting day.(3)C/EBP? and FAS expressions in resistin-overexpressing adipocytes were down-regulated after RBP was applied,without changing their expressions in normal adipocytes.(4)RBP had no effect on the cellular TG and FFAs levels in normal cells,whereas it can significantly decrease the levels in resistin-overexpressing adipocytes.(5)There was no difference in the expression of GLUT-4 gene between 3T3-L1 adipocytes and RBP-applied cells.Conclusions(1)RBP has no effect on the cell differentiation and lipid metabolism in normal 3T3-L1 adipocytes.(2)RBP can inhibit the cell differentiation and lipid metabolism of resistin-overexpressing 3T3-L1 cells.(3)RBP has no effect on the expression of GLUT-4 gene.

Objective To investigate the expression of S100A4 protein in benign and malignant thyroid tissues and its clinical significance. Methods Expression of S100A4 protein in thyroid cancers (50 cases), adenoma (45 cases) and adjacent noncancerous tissue (20 cases) was respectively studied by microwave-LSAB immunohistochemical staining. Results The positive rate of S100A4 protein in thyroid cancer and adenoma was 78.0% and 15.6% respectively. No S100A4 protein expression was found in any adjacent noncancerous tissue (P ＜0. 01). No correlation was observed between expression of S100A4 protein and histological grading of thyroid cancer. Expression of S100A4 protein in lymph node metastasis and staging Ⅲ-Ⅳ was both higher than that in negative cases and staging Ⅰ -Ⅱ (P ＜0. 05). The rate of recurrence and death in S100A4 protein positive cases were notably higher than that in negative cases (P ＜ 0. 05). Conclusions S100A4 protein expression can help to distinguish benign and malignant thyroid tissues. It can be used as a molecular marker to predict thyroid metastasis.

The vagus nerve is involved in the regulation of human inflammation, mood and pain. Stimulation of the vagus nerve has assured therapeutic effects on intractable epilepsy and refractory depression. On the surface of the human body, the ear is the only area in which vagal afferent fibers distribute. According to the "bottom-up" mechanism of the signal processing, the central nervous system can be modulated by stimulating the peripheral nerve. Therefore, stimulation of the vagus nerve can regulate the activities of brain stem, thalamus, cerebral cortex and other related areas to produce therapeutic effects. Transcutaneous vagus nerve stimulation is a safe, low-cost, non-invasive physical therapy modified from vagus nerve stimulation. This review focuses on the regulation of organ function by transcutaneous vagus nerve stimulation and its application to diseases treatment.
