Objective To assess the proficiency of water monitoring laboratory at rural, county, and provincial levels in Guangdong province, to ensure the province's drinking water monitoring results accurate and reliable. Methods State quality of certified reference materials as water arsenic, fluoride and chloride of 90 copies each were numbered and distributed to 90 monitoring laboratories in the province for testing, The measurement results of the participatory labs were evaluated through normative values and expanded uncertainty, and were compared with those of robust statistics method. Results All participatory labs had timely feedback of their measurement results. The qualified rate was higher when arsenic was tested by hydride generation atomic fluorescence spectrometry and zinc-new silver salt of sulfuric acid spectrophotometric system, while fluoride and chloride by ion chromatography. The average qualified rates of water arsenic, fluoride and chloride of the province's rural drinking water quality monitoring laboratory were 66% (59/90), 72% (65/90) and 72% (65/90), respectively.Seven participatory labs failed the proficiency testing of all three analytes and unqualified rate was 7.8% (7/90)among the ninety participated monitoring labs. The qualified rates of robust statistics method for arsenic fluoride and chloride were greater than those evaluated by the expanded uncertainty, and large deviations with small sample sizes. Conclusions The testing ability of drink-water monitoring labs in Guangdong province has improved.However, by comparison with the requirements of national quality control and testing skills, there is still a gap. It is suggested that internal quality control be included in routine inspeetion to improve laboratory testing technology.

Objective To develop a BP26 recombinant BCG (rBCG-BP26) vaccine,and to observe the effects of rBCG-BP26 on CD4+,CD8+ T cells in immunized mice.Methods The recombinant shuttle vector pMV261-Ag85B-BP26 was constructed by using traditional molecular biological technology.The recombinant strains were obtained by kanamycin resistance screening and PCR identification after electroporation.Western blotting was used to detect the expression of recombinant BP26 vaccine in immunized mice.Safety experiment was carried out in three different groups:the target experiment(rBCG-BP26) group,the positive control(BCG) group and the negative control(PBS) group,15 BALB/c mice in each group.Intradermal inoculations of 100 μl rBCG-BP26 [containing 106 colony forming units(CFU)],BCG,and PBS were carried out,respectively.Signs of mice in each group were observed.After immunization for 10,20,30,and 40 days,body weight was weighed,and tail blood was collected to observe the change of peripheral blood CD4+ and CD8+ T cells by flow cytometry.Results The rBCG-BP26 was successfully constructed.The expression of BP26 protein was detected in the liquid medium and the bacteria cells.The results of safety test analysis showed that there were no significant differences in signs and body weights(F=2.468,0.331,1.520,0.739,all P＞ 0.05),between PBS group[ (19.24 ± 0.54),(21.37 ± 0.66),(22.83 ± 0.62),(25.06 ± 0.37)g],BCG group[ (19.90 ± 0.02),(21.53 ± 1.57),(21.95 ± 0.55),(24.70 ± 0.39)g]and rBCG-BP26 group[ (19.16 ± 0.55 ),(20.89 ± 0.20),(22.15 ± 0.76),(24.60 ± 0.64)g].The results of flow cytometry showed that the percentages of CD4+ T cell level were lower in BCG group(26.70％,33.07％) and rBCG-BP26 group( 13.40％,26.70％) than that of the PBS group(33.85％,29.33％) and the values of CD4+/CD8+ T cells increased in rBCG-BP26 group (0.69％,1.27％,1.57％,1.70％ ) 10,20 and 30 days after immunization.Conclusions Recombinant BCG-BP26 vaccine strain can express brucella BP26 protein efficiently.Furthermore,its virulence is mild,and it can activate CD4+,CD8+ T cells in the body.It can be used as one of candidate vaccine strain against brucellosis.

Objective To evaluate the value of differential diagnosis on congenital biliary atresia(BA) and infantile hepatitis syndrome(IHS) by technetium-99m-diethyl-iminodiacetic acid(99Tcm-EHIDA)hepatobiliary scintigraphy with phenobarbitol sodium.Methods Fifty-eight infants with persistent jaundice were taken phenobarbitol sodium[5 mg/(kg?d)] ,bid ?7 d).Those who had not bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of BA.Those with bowel and gallbladders radioactivity within 24 hours were diagnosed as the diagnostic criterion of IHS,who then received 99Tcm-EHIDA hepatobiliary scintigraphy with single photon emission computed tomography(SPECT) instrument.The results of all children were analyzed and compared with pathology and clinical follow up results.Results 99Tcm-EHIDA hepatobiliary scintigraphy correctly diagnosed 24 infants with last diagnosis BA and 29 infants with last diagnosis IHS,5 neonates false positive in all 34 IHS patients.The sensitivity in the diagnosis of BA was 100%,the specificity and accuracy were 85.3% and 91.4%,restectively.The sensitivity was 85.3% in the diagnosis of IHS;the specificity and accuracy were 100% and 91.4%,respectively.Conclusions 99Tcm-EHIDA hepatobiliary scintigraphy with phenobarbitol sodium can accurately differentiate BA and HIS at early stage.

A fusion protein of glucagons-like peptide-1 and human serum albumin (GLP-1/HSA) was expressed and secreted into the fermentation broth with recombinant Pichia pastoris. The productivity of expressed GLP-1/HSA could reach 63.6mg/L in 10L fermentor. After concentrated with hollow-fiber ultrafiltration membrane, GLP-1/HSA was purified from fermentation broth by hydrophobic chromatography, negative ion exchange chromatography and gel filtration chromatography in turn. The HPLC analysis showed that the purified GLP-1/HSA had an overall purity of 95.8%. Furthermore, the analysis of in vivo activity indicated that GLP-1/HSA had the bioactivity of native GLP-1, and could significantly reduce blood glucose level 4h after intraperitoneal administration. It was concluded that a great deal of GLP-1/HSA with higher purity could be harvested by Pichia pastoris expression system and the established purification methods. Preliminary studies show a new potential for developing the long-acting GLP-1 analogs for clinical applications.
