Objective To understand the situation of iodine deficiency disorders of Cangzhou city, Hebei province, in order to provide the scientific basis for prevention and control of iodine deficiency disorders. Methods From 2007 to 2009, dynamic monitoring of iodine deficiency disorders was carried out in low iodized salt coverage places Hejian city and Xian county. Nine towns were randomly chosen in each county, 4 administrative villages were randomly selected in each town, 8 household salts were tested in each village. Every year, 1 - 3 copies of residents water samples were collected for determination of iodine; more than 100 students age 8 - 10 years old were checked the situation of goiter and urinary iodine, more than 40 students selected were measured iodine content of salt from their home; more than 50 women of childbearing age 18 - 40 years were tested of urinary iodine. Thyroid was examined with palpation; water iodine and urine iodine concentration were measured with arsenic-Ce catalytic spectrophotometry; salt iodine was detected by direct titration. Results From 2007 to 2009,median household salt iodine were 4.3,15.9,3.6,18.4,4.6,11.7 mg/kg in Hejian city and Xian county, respectively,iodized salt accounted for 34.03% (98/288), 78.82% (227/288), 29.86% (86/288), 84.72% (244/288), 37.15%(107/288),49.31% (142/288), respectively, the consuming rate of iodized salt were 27.08% (78/288),36.46%( 105/288 ), 28.13% (81/288 ), 49.31% ( 142/288 ), 37.15 % ( 107/288 ), 30.90% ( 89/288 ), respectively. Ten samples of drinking water were tested, water iodine were 5.5 - 34.4 μg/L. From 2007 to 2009, the goiter rate of students aged 8 - 10 years old was below 5%, the median of urinary iodine were 138.1,176.6,112.0 μg/L, ＜ 100 μg/L ratio were 31.6% ( 65/206 ), 25.0% ( 52/208 ) and 44.4% (91/205 ). The median of urinary iodine of child-bearing age women were 167.3,164.2,78.1 μg/L, ＜ 100 μg/L ratio were 28.7%(29/101 ), 19.2%(20/104) and 60.0%(60/100).Conclusions In areas with low coverage of iodized salt, iodine nutrition level are affected, the child-bearing age

The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.

In order to select high quality and suitable Bupleuri Radix varieties in Qingchuan, and establish a new comprehensive method to evaluation the quality of Bupleuri Radix, 12 characters of 14 samples were evaluated by DTOPSIS and grey related degree. The results showed that varieties No. 8 and No. 10 had high quality. DTOPSIS and grey related degree gave the uniformity result, and the biggest difference of value of Ci in DTOPSIS method was 46. 33% , but the biggest difference of the weighting correlation number( r (i)) in grey related degree was only 13.10%. The DTOPSIS combined with grey related degree can evaluate the quality of Bupleuri Radix comprehensively and objectively.

OBJECTIVETo observe the changes of telomere length and telomerase activity in patients with aplastic anemia (AA), and relationship with immunosuppressive therapy (IST) efficacy, to explore the pathogenesis of AA and the role of telomere length in evaluating immunosuppressive therapy efficacy.

METHODS71 cases of AA patients between September 2010 and March 2013 were enrolled into this study. 3 ml peripheral blood specimens from this cohort of patients were collected to test the telomere length in peripheral blood mononuclear cell (PBMNC) with flow-FISH and detect telomerase activity with TRAP-PCR-ELISA method.

RESULTSTelomere length and age showed negative correlation (b=-0.387, P=0.001) in normal control, NSAA and SAA + VSAA groups, telomere length became shorter with the growth of age, and normal control group telomere length decreased along with the age growth slightly greater than the other two groups (NSAA, SAA+VSAA). Besides the effect of age on telomere length, no significant difference was observed between NSAA and SAA+VSAA groups (P=0.573), and NSAA, SAA+VSAA (30.957 ± 4.502,29.510 ± 5.911)groups were significantly shorter than normal control group (51.086±10.844) (P<0.01). Telomere length in NR group (25.357±4.848)was significantly lower than normal control group (51.086 ± 10.844) (P=0.005), telomere length in CR(32.808 ± 4.685)/PR groups (30.334±4.464) compared with normal control group had no significant difference (P=0.517, P=0.254). Telomere length below 29.21% obviously decreased outcomes of IST. Telomerase activity had significant difference (χ²=20.385, P<0.01). The telomerase activity had no significant difference in terms of age and gender in three groups, multiple comparison found that telomerase activities in SAA + VSAA (0.324±0.178) (P<0.01), and NSAA (0.234±0.175) groups (P=0.002) were significantly higher than normal control group (0.107±0.083).

CONCLUSIONTelomere length of PBMNC in AA patients was significantly shortened than normal control group with telomerase activity increased, and telomere shorted more apparently in NR group, these patients should adjust the treatment as early as possible. Telomeres could predict the curative effect of IST.

UNLABELLEDThe purpose of this study was to evaluate the effects of cellular immunity activation on P58(+) cells expressing killer cell inhibitory receptor (KIR) and their regulatory function on cellular immunity, and provid theoretical data for preventing graft-vers-host disease (GVHD) in stem cell transplantation therapy. The mononuclear cells from human peripheral blood were incubated with IL-2, Con A and Lipostin (LP) for 72 hours. The KIR expressing cells, P58.1(+) and P58.2(+) cells, were analyzed by flow cytometry. The results showed that the percentages of CD3(+), CD4(+), CD8(+), CD16(+)CD56(+), P58.1(+) and P58.2(+) cells were greatly increased after treated with IL-2, Con A and LP, separately or in combination, and the percentages of above cells in combined treatment groups were higher than those of single stimulated groups, especially the percentage of cells in the IL-2 + LP group was significantly higher than those in IL-2 and LP singly treated groups.

IN CONCLUSIONIL-2, Con A and LP possess the ability to induce the expression of KIR and stimulate proliferation of P58.1(+) and P58.2(+) cells while to activate the celluar immunity response, the expression of P58 gene may be regulated by the activation of cellular immunity.

OBJECTIVEA comparative proteomic approach was used to identify and analyze proteins relevant to metastasis of hepatocellular carcinoma (HCC).

METHODSProteins extracted from 12 liver tumor tissue specimens (6 with metastases and 6 without) were separated by two-dimensional gel electrophoresis (2-DE). Comparative analyses of 2-DE protein patterns between the two groups were done using computerized image analysis. Selected proteins exhibiting statistically significant alternations were identified by mass spectrometry. Immunohistochemistry, Western blotting and RT-PCR were performed to examine the expressions of the candidate proteins.

RESULTS16 proteins including HSP27, S100A11, CK18 were identified using mass spectrometry, which were related to cell mobility, signal transduction, and energy metabolism respectively. Of these, HSP27 was found to be uniquely over-expressed in 2-DE maps of all metastatic HCCs when compared to the non-metastatic HCC tissues. Immunohistochemistry and Western blotting of HCC tissues confirmed this difference while RT-PCR did not.

CONCLUSIONThere are different proteins working together that affect the metastasis of HCCs. The overexpression of HSP27 may serve as a biomarker for early detection and therapeutic targets to the metastatic phenotype of HCC. The role of HSP27 in HCC metastasis warrants further investigation.
