Objective To investigate the diagnosis value of mucin 7 in plasma and urine in the detection of bladder cancer.Methods Expression of mucin 7 was detected quantitatively in plasma and urine from 23 patients with bladder cancer and 23 patients as control group by enzyme-linked immunosorbent assay(ELISA) from November 2012 to September 2013.There were 15 were male and 8 were female in the 23 bladder cancer patients,aged from 41 to 95 years,with an average of 64 years.Of the 23 bladder cancer pathology,12 with high grade,11 with low grade,11 with invasive disease and 12 with noninvasive disease.There were 19 males and 4 females in the 23 patients in control group,aged from 28 to 85 years,with an average of 61 years.Results The amount of mucin 7 in plasma was significantly higher in bladder cancer group than that in control group [(7.43±4.54) ng/ml versus (4.55±.1.98) ng/ml,P=0.017].While there was no significant difference in urine between the two groups [(12.44±7.1 1) ng/ml versus (11.96±8.41)ng/ml,P=0.840].There was no significant differences in the amount of mucin 7 had in different grades and stages of bladder cancer (P＞0.05).Conclusions Expression of mucin 7 in plasma of patients with bladder cancer is significantly higher than that in control group.Mucin 7 expression has no significant correlation with the grading and staging of bladder cancer.Detecting mucin 7 expression quantitatively with ELISA for diagnosis of bladder cancer is a method with certain value.

Our investigation was conducted in order to verify a recent severe epidemic at several swine farms in northern China that indicated a newly emerging disease. Evidence confirmed that the epidemic was caused by a virulent Pseudorabies virus infection in swine herds.

On account of the problem that traditional C-arm X-ray apparatus cannot provide precise route guidance for minimally invasive surgeries, we designed and developed a laser positioning and navigation system based on C-arm X-ray apparatus, which can achieve precise positioning function and reduce the exposure of doctors and patients to radiation in minimally invasive surgeries under the linear guidance of a laser beam. Furthermore, this system can enhance the refinement level of surgical operation in minimally invasive surgeries.

【Objective】 To investigate the hepatitis E virus(HEV) infection among voluntary blood donors in Liuzhou, Guangxi. 【Methods】 Qualified blood donations in Liuzhou from October to November 2019 were tested for anti-HEV IgG and IgM and.HEV antigen. HEV RNA test was performed on samples positive for HEV antigen and/or anti-HEV IgM. and the test results were analyzed statistically. 【Results】 The seroprevalence rates of HEV antigen and anti-HEV IgG and IgM among 5 751 qualified donations were 0, 26.03% (1497/5 751), and 1.67% (96/5 751), respectively.None of the 91 anti-HEV IgM positive samples was positive for HEV RNA, whereas 60.41% of anti-HEV IgM positive samples were anti-HEV IgG positive. The HEV antibody prevalence varied significantly by gender, age, and nationality (P<0.05). 【Conclusion】 The prevalence of anti-HEV IgG / IgM among blood donors in Liuzhou was higher than that in other domestic regions. Significant increase in HEV antibody prevalence was observed among ethnic minorities, such as Miao and Dong, and age group of more than 45 years.Follow-up studies with larger sample size could be conducted to estimate potential risks of HEV transmission by blood transfusion, which may provide references for selective screening of HEV infection marker among high-endemic population.
