OBJECTIVETo construct a recombinant lentiviral vector (pXZ208-BDDhFVIII) mediating B-domain-deleted human coagulation factor VIII (BDDhFVIII) gene and investigate its expression in HLF, Chang-Liver and MSC cells.

METHODSBDDhFVIII gene fragment was separated by endonuclease digestion and was cloned into the multiple cloning sites of pXZ208 to construct a recombinant lentiviral vector pXZ208-BDDhFVIII. Viral particles were prepared by means of three-plasmid cotransfection of 293T package cells by calcium phosphate precipitation. After infection, the coagulant activity of human FVIII in the culture medium of 293T, HLF, Chang-Liver and MSC cells was assayed by one-stage method. The gene transduction efficiency was assayed by flow cytometry (FCM). Furthermore, PCR was performed to test the integration of BDDhFVIII.

RESULTSThe infection rates of HLF, Chang-Liver and MSC were (74.52 +/- 7.57)%, (27.24 +/- 6.53)% and (42.34 +/- 5.84)% respectively. The activities of FVIII in supernatants of HLF, Chang-Liver and MSC were (54.1 +/- 5.6)%, (22.5 +/- 2.9)% and (12.5 +/- 2.7)% respectively. BDDhFVIII gene integration was detected in all the infected cells.

CONCLUSIONThe recombinant lentiviral vector pXZ208-BDDhFVIII was successfully constructed and efficiently integrated into target cells to express human FVIII activity in vitro.

In order to effectively remove the invalid impurities in Tongan injection, optimize the optimal parameters of the impurity removal technology of liquid mixing process, in this paper, taking Tongan injection as the research object, with the contents of celandine alkali, and sinomenine, solids reduction efficiency, and related substances inspection as the evaluation indexes, the removal of impurities and related substances by the combined process of refrigeration, coction and activated carbon adsorption were investigated, the feasibility of the impurity removal method was definited and the process parameters were optimized. The optimized process parameters were as follows: refrigerated for 36 h, boiled for 15 min, activated carbon dosage of 0.3%, temperature 100 degrees C, adsorption time 10 min. It can effectively remove the tannin, and other impurities, thus ensure the quality and safety of products.

We reports a nursing process for one uremic patient undergoing peritoneal dialysis during pregnancy.The key of this case is:through the closely follow-up by the specialist nurses in peritoneal dialysis center,the center could find problems and make treatments,and adjust the prescription timely;by effective observation and nursing care,the center reduced the incidence of peritoneal dialysis related infection and minimized the risk;the center provided strong supports for the patient including close examination of fetal,individual diet guidance and psychological support.With all the efforts,the center eventually ensured the safety and stability of the patient during pregnancy.

Objective To understand the situation of iodized salt consumption at the household level and non-iodized salt distribution in those areas with low iodized salt coverage.Methods In 2010,iodized salt was monitored in 31 provinces and Xinjiang Production and Construction Corps in accordance with the Monitoring Program of the National Iodine Deficiency Disorders (Trial) (hereinafter referred to as the Program) requirements.Under the jurisdiction of counties (cities,districts,banners) with more than 9 townships (towns,street offices),based on the location of east,west,south,north and center,9 townships (town,district offices) were selected using simple random sampling method; 4 administrative villages (neighborhoods) were selected in each township (town,district office); and 8 residents in each administrative village (neighborhood) were selected.Under the jurisdiction of counties (cities,districts,banners) with less than 9 townships (towns,street offices),based on the location of east,west,south,north and center,1 township(town,district office) was selected using simple random sampling method; 4 administrative villages(neighborhoods) were selected in each township(town,district office);and 15 residents in each administrative village(neighborhood) were selected.Iodized salt coverage rate,qualification rate of iodized salt and consumption rate of qualified iodized salt were calculated in various provinces.The salt samples were tested by semi-quantitative method on the spot and then tested with quantitative method in laboratories.The standard of qualified iodized salt was set as 20-50 mg/kg and that of non-iodized salt was set as ＜ 5 mg/kg (GB/T 13025.7-1999).Results In 2010,a total of 2862 counties(districts,cities and banners) and 14 divisions of Xinjiang Production and Construction Corps,reported the monitoring results,and the monitoring coverage rate was 99.79％(2876/2882).A total of 826 696 copies of edible salt samples were tested,the coverage rate of iodized salt was 98.63％,the consumption rate of qualified iodized salt was 97.95％,and the coverage rate of qualified iodized salt was 96.63％.At province level,only in Tibet iodized salt coverage rate was ＜ 90％.At county level,2755 counties qualified iodized salt coverage rate was ≥90％,and 33 counties iodized salt coverage rate was ＜ 80％.The counties with qualified iodized salt coverage rate of 90％ or more accounted for 96.63％(2785/2882) of the total counties.Conclusions The counties where non-iodized salt coverage is higher than 20％ mainly distributed in the western or coastal areas and adjacent areas with higher iodine.These areas need policy and funding support from governments at all levels to reducc the gap between these areas and other areas.

Objective To study the national surveillance results and learn the current situation of iodized salt consumption at household level in 2008, and to find out the remaining problems and to provide scientific basis for developing control strategies against iedine deficiency disorders. Methods In 2008, in accordance with the requirements of the "National Iodine Deficiency Disorders Surveillance Program (Trial)", the surveillance was conducted at county level in 31 provinces and at division level in Xinjiang Production and Construction Corps. In each county 9 townships were randomly selected according to their sub-area positions of east, west, south, north and center;4 villages were randomly sampled in each chosen township;8 households were randomly selected in each chosen village. In every county with 9 or less townships, 1 township was randomly selected respectively in the east, west, south,north and center sub-areas;4 villages were randomly sampled in each chosen township;15 households were randomly selected in each chosen village. Edible salt from these households was collected. Iodized salt coverage rate, proportion of qualified iodized salt and consumption rate of the qualified iodized salt of the households in each province were counted and analyzed. Iodized salt was determined by direct titration;the salt samples from Sichuan and other enhanced salt were detected by arbitration. Results Totally 2817 counties (districts, cities, banners) and 14 divisions of the Xinjiang Production and Construction Corps reported the monitoring results, monitoring coverage reached 99.96%(2831/2832). Mean of iodine content was 31.51 mg/kg.Sixteen provinces had a variation coefficient of iodine content for more than 20%. A total of 826 968 households were tested of their edible salt, in which iodized salt 798 725 copies, non-iodized salt 28 243 copies, and unqualified iodized salt 20 270 copies. Weighted by population,at national level, the coverage rate of iodized salt was 97.48%, qualified rate of iodized salt 97.16%, and consumption rate of qualified iodized salt was 94.79%.Twenty seven provinces (autonomous regions and municipalities) and Xinjiang Production and Construction Corps had a qualified iodized salt coverage rate of above or equal 90.00%. Tibet, Hainan, Xinjiang and Tianjin provinces (regions) had a qualified iodized salt coverage rate lower than 90.00%. Further, 2487 counties had the rate high or equal 90.00% accounting for 87.82% (2487/2831) of complementing monitoring counties. One hundred and four counties and 1 division of the Xinjiang Production and Construction Corps had the coverage rate of iodized salt below 80.00%. Conclusions Sixteen provinces(autonomous regions and municipalities) have relatively a high degree of variation coefficient in salt iodine content. The quality of iodized salt needs to be improved. The coverage rate of iodized salt and the qualified iodized salt at national level are both above or equal 90.00%. However, the non-iodized salt problem is still serious and have a relatively lower coverage of iodized salt in Tibet, Hainan and Xinjiang.
