Objective: To analyze the exposure level and the geographical distribution trend of toxicological indicators of rural drinking water in Shandong Province. Methods: The drawing method was used to randomly select no less than 60% villages and towns from 137 counties (cities, districts) of 17 cities in Shandong Province in 2015, and then 1-3 rural centralized water supply units were selected according to the circumstance of rural centralized water supply units in each village and town. In total, 735 villages and towns, 1 473 rural centralized water supply units were selected, and 1 473 water samples were collected. The water treatment process, water supply population and other circumstances of the rural centralized water supply units were investigated, the water quality was monitored, the content of toxicological indicators of drinking water in different areas was compared, and the trend surface isogram of excessive toxicological indicators was drawn. Results: The qualified rate of toxicological indicators in 1 473 water samples was 83.64% (n=1 232). The main toxicological indicators that affected the qualified rate of toxicological indicators of drinking water in rural areas in Shandong Province were nitrate and fluoride. The excessive rate of fluoride was 5.70% (n=84) and the exposed population was 1 736 709 (4.22%). The excessive rate of nitrate (as nitrogen) was 12.29% (n=181) and the exposed population was 1 393 612 (3.39%). The P₅0 content of fluoride in the eastern, middle and western regions was 0.24, 0.29 and 0.59 mg/L, respective;which was higher in the western region than in the east and the middle regions (P<0.05). There was no significant difference between the eastern and the middle regions (P>0.05). The P₅₀ content of nitrate (as nitrogen) in the eastern, middle and western regions was 8.00, 7.48, and 2.00 mg/L, which was higher in the eastern and middle regions than in the west region (P<0.05), there was no significant difference between the eastern and the middle regions (P>0.05). The trend surface isogram of nitrate and fluoride content showed that the content of nitrate (as nitrogen) in rural drinking water in the eastern region was significantly higher than that in the western region, especially there was a high peak area in the northeastern region, and this high content distribution extended diagonally to the central region, while the other regions were in a relatively low range. The content of fluoride in rural drinking water in the western region was significantly higher than that in the eastern region, and there were high peaks in the southwest and northwest regions, and the other regions were in a relatively low range. Conclusion The high exposed toxicological indicators in rural drinking water in Shandong Province were nitrate (as nitrogen) and fluoride, and their distribution showed obvious geographical distribution trend.

The infection rate of AIDS among the supervised persons in the supervision places is high, thus the work-ers’ chance of getting into contact with HIV infected persons or AIDS patients increases and the risk of having occupa-tional exposure gets larger. Through introducing the common situation, risk factors and preventative treatment measures, this paper explores the effective preventative countermeasures and suggests to enhance the management of HIV infected supervised persons, increase the establishment of AIDS occupational exposure protection facilities, strengthen occupa-tional safety education, improve the workers’ protection knowledge and skills and take proper treatment measures after exposure in order to reduce occupational hazards.

OBJECTIVETo construct a personalized full-length fully human antibody mammalian display library for children with systemic lupus erythematosus (SLE).

METHODSThe total RNA was isolated from the PBMCs of SLE children. The heavy chain variable region and kappa light chain (VH and LCκ) of the antibody genes were amplified by RT-PCR and inserted into the pDGB-HC-TM vector separately to construct the heavy chain and light chain libraries. The library DNAs were transfected into 293T cells and the expression of full-length fully human antibody on the surface of 293T cells was analyzed by flow cytometry.

RESULTSUsing 0.8 µg total RNA as the template, the VH and LCκ were amplified and the full-length fully human antibody mammalian display library was constructed. The VH and LCκ gene libraries had a size of 9.4×10(4) and 8.4×10(4), respectively. Sequence analysis of 10 clones randomly selected from the VH and LCκ gene libraries each showed that 8 heavy chain clones and 7 light chain clones contained correct open reading frames, and flow cytometry demonstrated that all the 15 clones express full-length antibodies on 293T cell surfaces. 293T cells co-transfected with the VH and LCκ gene libraries expressed the full-length antibodies on the cell surface.

CONCLUSIONThe personalized full-length fully human antibody library for SLE children constructed allows display of the full-length antibodies on mammalian cell surfaces, thus providing a valuable platform for analyzing the autoantibodies, their etiological role, and their clinical implications in SLE.

Objective: To explore the value of superb micro-vascular imaging(SMI) combined with conventional ultrasound in differential diagnosis of polypoid lesions of gallbladder. Methods: The ultrasonographic and pathological datas of 67 patients with polypoid lesions of gallbladder (of ≥1 cm) in diameter were analyzed retrospectively. According to the pathological results, the patients were divided into tumorous polyp group and non-tumorous polyp group.Conventional ultrasound, SMI and contrast-enhanced ultrasound (CEUS) were performed in all patients before operation, and the basal width, continuity of cystic wall and internal blood flow morphology of polyps were evaluated. The ROC curve was used to calculate the area under the curve and the optimum boundary value of tumorous polyps, the sensitivity and specificity of SMI combined with conventional ultrasound in the diagnosis of neoplastic polyps were calculated according to the optimal threshold. Kappa consistency test was used to analyze the consistency between microblood flow ability and CEUS shown by SMI technique. Results: Of the 67 patients, 22 cases were neoplastic polyps, and 45 cases were non-neoplastic polyps.The polyps were scored quantitatively by SMI combined with conventional ultrasound (0-9 points) and the ROC curve was plotted with, area under curve 0.893(95% CI 0.792-0.994). The sensitivity, specificity and accuracy of diagnosing neoplastic polyps with score (≥4.5) were 77.3%, 93.3% and 88.1%, respectively. Compared with the score of CEUS for microblood flow display (0-4 points), the Kappa values of CDFI, SMI was 0.186, 0.688. SMI and CEUS have good consistency. Conclusions SMI combined with conventional ultrasound is helpful in differential diagnosis of polypoid lesions of gallbladder, with a high diagnostic value. SMI and CEUS have good consistency in the display of micro-blood flow. It can provide a new diagnostic basis for differential diagnosis of polypoid lesions of gallbladder.
