To establish a cell-based rapid luciferase suppression assay for high-throughput screening (HTS) anti-alphaviruses compounds screening, which could cause viral encephalitis, raise the social issues associated directly with public health and huge economic burden to the society. The Gaussia luciferase assay system was used for HTS model for identifying inhibitors of labeled virus XJ160-GLUC. The decreased 50% GLUC activity inhibition ratio was deemed to be the screening positive index. The reaction system in this model was optimized, and the reliability of the model was evaluated. For HTS model's optimization, cells were infected with XJ160-GLUC at an MOI of 0.025 PFU/cell. The supernatant treated with compounds 48h were collected for GLUC expression detection. In the model, Z' factor was up to 0.71, demonstrating that HTS assay for identifying inhibitors that target all aspects of the viral life cycle of XJ160-GLUC was stable and reliable. After screening 8080 compounds (five-in-one), 341 positive samples were selected, and the positive rate was 4.2% with a cutoff at 50% inhibition. Then 1705 compounds were screened subsequently and the positive rate was 1.1% with obtaining 19 positive compounds. These results will lay the foundation for finding the anti-alphaviruses' drug targets.

Objective: To evaluate the impact of CO₂ pneumoperitoneum in operating rooms on the health of medical staffs. Methods: In June 2016, the thirty-three medical staffs in operating rooms were chosen as the object of the research.Seventeen people who took part in the pneumoperitoneum operation were selected as a exposure group and sixteen people who took part in the laparotomy operation were selected as a control group.Vital signs and arterial blood gases of medical staffs in the two groups were both measured in pre-operation and post-operation. Occupational Health Questionnaires were conducted to collect information on age, weight and postoperative symptoms. The level of CO₂ in operating room was determined by a portable infrared CO₂ analyzer. Results: Compared with the control group, the concentration of CO₂ in the exposed group was higherat T₁, T₂ and T₃ (t=22.227, 13.583, 17.408, P<0.05) . Heart rates and PaCO₂ in the exposure group raised greatly (t=2.132, 2.129, P<0.05) , while pH decreased (t=-3.015, P<0.05) . The differences between the two groups were statistically significant. Conclusion The increase of mild acidosis and thesense of job burnout in medical staffs could be caused by CO₂ pollution in the operating rooms.

Objective To explore the indications for percutaneous renal biopsy of asymptomatic hematuria in children. Methods The renal pathological types of 485 children with asymptomatic hematuria were analyzed retrospectively. According to the degree of hematuria and whether or not combined with proteinuria, the children were divided into microscopic hematuria group, gross hematuria group and hematuria with proteinuria group. The microscopic hematuria group was further divided into urine red blood cell<15/HPF group, (15～30)/HPF group, and >30/HPF group according to hematuria degree. Results In 227 males and 258 females with the average age of 7.23±2.93 years, there were 318 cases in microscopic hematuria group, in which the most common pathological types were minor lesions (64.8%), followed by focal glomerular lesions (16.7%) and focal segmental glomerulosclerosis (8.2%). There were 119 cases in gross hematuria group, in which the most common pathological types were also minor lesions (26.1%), followed by IgA nephropathy (24.4%) and mesangial proliferative glomerulopathy (20.2%). There were 48 cases in hematuria with proteinuria group, in which the most common pathological types were IgA nephropathy (29.2%) and minor lesions (29.2%). The distribution of the pathological types among microscopic hematuria group, gross hematuria group and hematuria with proteinuria group were statistically different (χ2=152.03, P<0.001). In three groups, microscopic hematuria group had the highest proportion of minor lesions, while gross hematuria group and hematuria with proteinuria group had higher proportion of IgA nephropathy and mesangial proliferative glomerulonephritis . In microscopic hematuria group, there were 149 children with urine red blood cell<15/HPF, 96 with urine red blood cell (15～30)/HPF, and 73 with urine red blood cell >30/HPF. There was no difference in pathological types among three sub-groups (χ2=15.18, P=0.51), and mild lesions were the most common pathological types in each group. Conclusion Renal biopsy should be performed at earliest possible time to make pathological diagnosis in asymptomatic hematuria children with gross hematuria or proteinuria.
