Porcine reproductive and respiratory syndrome is caused by the PRRS virus(PRRSV), which has six structural proteins(GP2, GP3, GP4, GP5, M and N). GP5 and N protein are important targets for serological detection by enzyme-linked immunosorbent assay(ELISA)and other methods. Toward this goal, we developed an indirect ELISA with recombinant GP5 antigens and this method was validated by comparison to the LSI PRRSV-Ab ELISA kit. The results indicated that the optimal concentration of coated recombinant antigen was 0.2 μg/well for a serum dilution of 1:40. The rate of agreement with the LSI PRRSV-Ab kit was 88.7%(266/300). These results support the potential use of recombinant GP5 as an antigen for indirect ELISA to detect PRRSV antibodies in pigs.

Objective To investigate the clinical significance of individualized neoadjuvant chemotherapy for renal carcinoma to reduce side effects under the guidance of gene detection.Methods From January 2011 to March 2014,two hundred and twelve patients with renal carcinoma treated in Cangzhou Central Hospital were enrolled in the study and randomly divided into the gene detection group (102 cases) and non-gene detection group (110 cases).The gene detection group was detected by the real time fluorescence quantitative (RT-PCR) method and the drug sensitivity test was carried out,and the patients were given neoadjuvant chemotherapy based on the results of drug sensitivity test.The patients in the non-gene detection group were treated with the national comprehensive cancer network (NCCN) experience regimen.The incidence of chemotherapy side effects was compared between the two groups.Results The 1 year survival rate of the gene test group was higher than that in the non-gene detection group (87.25％ (89/102) vs.77.27％ (85/ 110),x2 =4.67,P＜0.05),and the 3 year survival rate increased (70.58％ (72/102) vs.64.54％ (71/110),x2 =4.510,P＜ 0.05) as well,the differences were statistically significant (P ＜ 0.05).The incidence of liver injury in the gene detection group was 17.64％ (18/102),which was lower than that in the control group 30％ (33/110),the difference was statistically significant (x2 =4.42,P ＜ 0.05).In the gene detection group,the incidence of leukocyte 3～4 level inhibition was 27.5％ (28/102),which was higher than that in the non-gene detection group 21.8％ (24/110).The difference was statistically significant (x2 =4.940,P ＜ 0.05).Conclusion Genetic polymorphisms detection is a guide to the application of tumor sensitive drugs in the individualized neoadjuvant chemotherapy of renal carcinoma.It can improve the therapeutic effect,and also reduce the occurrence of liver injury caused by side effects of chemotherapy and has high clinical application value.

Objective: To explore the association of latent profiles of mobile phone dependence and self control with physical exercise among junior high school students, so as to provide references for the prevention of mobile phone dependence and the improvement of self control among junior high school students. Methods: From April to May 2024, a stratified random cluster sampling method was used to select a total of 2 311 students from grade 7 to grade 9 in three public junior high schools in Xiangxi Autonomous Prefecture, Hunan Province. Latent profile analysis was conducted to identify the latent profiles of mobile phone dependence and self control among junior high school students. Pearson correlation analysis was used to examine the correlation between mobile phone dependence and self control, and Chi square test was used to analyze the distribution differences of latent profiles of adolescents across different demographic characteristics. Multiple Logistic regression analysis was applied to explore the association between mobile phone dependence, self control, and physical exercise. Results: Four latent profiles of mobile phone dependence and self control were identified: low dependence-moderate self control group ( n =885, 38.3%), moderate dependence-low self control group ( n =910, 39.4%), high dependence-no self control group ( n =232, 10.0%), and no dependence-high self control group ( n =284, 12.3%). Significant differences were observed in the distribution of latent profiles across gender, grade and only child status ( χ 2=10.85, 35.72, 13.85， P <0.05). Logistic regression analysis showed that, after controlling for demographic variables, compared with the low dependence-moderate self control group, physical exercise was negatively associated with the moderate dependence-low self control group ( OR =0.79) and the high dependence-no self control group ( OR =0.81), while positively associated with the no dependence-high self control group ( OR =1.58) ( P <0.01). Conclusions The influence of physical exercise on junior high school students different potential profile types of mobile phone dependence and self control is different. Schools and families should adopt targeted physical exercise interventions based on the characteristics of different profiles to promote the physical and mental health of junior high school students.

Background and objective Epidermal growth factor receptor (EGFR) and KRAS gene are important driver genes of non-small cell lung cancer (NSCLC).The studies are mainly focused on detection ofEGFR gene for advanced NSCLC,and the mutation feature of EGFR and KRAS gene in early NSCLC tissue is unknown.This study aims to investigate the mutations of EGFR and KRAS gene in NSCLC,and the relationship between the genotype and clinicopathologic features.Methods The hotspot mutations in EGFR and KRAS gene in 754 tissue samples of stage Ⅰ-Ⅲa NSCLC from Department of Pathology,Peking Union Medical College Hospital were detected by modified amplification refractory mutation system (ARMS) real-time PCR kit,and analyzed their correlation with clinical variables.Results The hotspot mutation rates in EGFR and KRAS were 34.5％ and 13.1％ respectively,and there were EGFR-KRAS double mutations in 3 samples.The mutation rate of EGFR was higher in females than that in males (39.5％ vs 29.4％,P=0.076),significantly increased in adenocarcinomas (38.7％) compared to that in the other forms of NSCLC (P＜0.01),but still lower than that reported in some Asian studies of advanced adenocarcinoma (-50％).Meanwhile,the mutation rate of KRAS was remarkably higher in males than that in females (16.6％ vs 9％,P=0.048),increased in adenocarcinomas compared to that in the other forms of NSCLC,but the difference was not significant (P=0.268).Samples harbored EGFR mutation were younger than those harbored KRAS mutation (P=0.031,5),and had significant difference in gender between the two groups (P＜0.01).Conclusion The mutation rate of EGFR in stag Ⅰ-Ⅲa NSCLC patients was lower than that in advanced NSCLC patients.And the percentage of the NSCLC patients with EGFRKRAS double mutations is 0.9％.
