Objective To evaluate the effect of immune fluorescence chromatography on glycosylated hemoglobin (HbA1c). Methods The precision of immune fluorescence chromatography was evaluated with samples of 6.0% and 8.0% fixed value. Group of High performance liquid chromatography (HPLC) as control, HbA1c for 200 samples of EDTA-K2 anti-coagulated whole blood were detected by immune fluorescence chromatography to synchronous blinded trial. Results As to the precise of immune fluorescence chromatography in the samples of 6% and 8%, values of coefficient of variation were 5.1% and 5.3%, respectively. The linear regression equation of immune fluorescence chromatography and HPLC was Y=-0.110+1.021X and the correlation coefficient was 0.982. 6.0% and 8.0% as the cut-off value, kappa values were 0.950 (P < 0.001) and 0.922 (P < 0.001), respectively. Conclusion Immune fluorescence chromatography and HPLC is consistent with detection of HbA1c, which can be used for clinical detection of HbA1c.

Objective:To analyze the mechanism on integration of health care services at the county and town-ship level from the perspective of stakeholder theory. Methods: The stakeholder interest demand was determined by word frequency analysis of interview data from stakeholders in the three regions of Qianjiang, Huangpi, and Zhen-jiang;the degree of attention and gains and losses of stakeholders towards various demands was investigated from the three regions through interest demand questionnaires;the impact of demand benefits on behavioral responses has been evaluated through comprehensive evaluation theory and game theory. Results:Regional integration policies reflect the interest demands of stakeholders in varying degrees; the higher were the scores of demand benefits in interest de-mands questionnaires, the stronger was the willingness of stakeholders to coordinate integration policies. Conclusion:The policies of integration of health care services in rural China should consider all stakeholder interest demands;the better the interest demands of the stakeholders are satisfied, the stronger their motivation for integration reform will be, which may affect the implementation effects of local integration reforms to some extent.

Objective: To reconstruct adenovirus vector of breast eukaryotic initiation factor 4E and to observe its effect on the metastasis ability of breast cancer cell line MCF-7. Methods: eIF-4E gene was constructed into adenovirus vector pAD-X by gene recombination technique, which was transformed into 293 packaged cell for high titer adenovirus. Real-time PCR was applied to detect eIF-4E gene expression. eIF-4E siRNA was applied and then transwell cabin assay was used to observe changes of invasion and motor ability of MCF-7 cells transfected with reconstruction adenovirus. Result:The finding of digestion was coincided with expected. eIF-4E gene over-expression was detected in transfected MCF-7 cells with real-time PCR. And the invasion and motor abilities of transfected MCF-7 cells were more significantly inhibited in transwell cabin assay (respectively p

Objective To observe the effect of high iodine on mRNA expression of thyroid hormone receptor (TSHR),protein kinase A (PKA) and sodium iodide symporter (NIS) in peripheral blood of patients with thyroid diseases during lacatation.Methods A total of 99 breast-feeding women were selected as observation objects in Shanxi Province's sufficient iodine and high iodine areas,and they were divided into case group and control group according to whether suffer from thyroid disease.In high iodine areas,there were 21 patients and 19 healthy controls.In sufficient iodine areas,there were 30 patients and 29 healthy controls.Peripheral blood of all the observation objects was collected,and mRNA expression of TSHR,PKA and NIS was detected by real-time quantitative PCR.Results The case group [median (M):0.099,0.994] and the control group (M:0.240,0.738) in the high iodine areas were respectively compared with the case group (M:3.087,1.127) and the control group (M:1.823,0.842) in the sufficient iodine areas.The TSHR mRNA expression was significantly decreased (Z =-5.034,-4.010,all P < 0.01);the PKA mRNA expression had a downward trend,and the difference was not statistically significant (Z =2.895,-0.343,all P> 0.05).The NIS mRNA expression of the case group in high iodine areas (M:0.485) was obviously lower than that of the the case group in sufficient iodine regions (M:2.680,Z=-3.311,P < 0.01).The control group in high iodine areas (M:0.470) was compared with the control group in sufficient iodine areas (M:0.835),and the difference was not statistically significant (Z =-1.882,P > 0.05).The NIS and the TSHR mRNA were positively correlated [correlation coefficient (r) =0.741,P < 0.01];the NIS and the PKA mRNA was also positively correlated (r =0.293,P < 0.01);but the TSHR mRNA was not significantly correlated with the PKA mRNA (r =-0.081,P > 0.05).Conclusion Lactating women may have protected themselves and their babies through TSH-TSHR-cAMP-PKA signaling pathway that regulating iodine levels.

OBJECTIVE:To analyze the dyeing status of cinnabar and its pieces,and provide reference for its quality clinical safetey appicaton. METHODS:TLC was used for the qualitative identification of amaranth,carmine,erythrosine,acid red 73, 808 udan and indirubin. HPLC-MS was used to detect the 808 udan :HPLC conditions were as follows,column was Acquity UPLC BEH C18 with mobile phase of cetonitrile-0.1% formic acid(70∶30,V/V)at a flow rate of 0.3 ml/min,the detection wave-length was 520 nm;MS conditions were as follows,ion source was electrospray ionization source,scanning mode was positive ion scanning with full scanning tandem mass spectrometry,nebulizer pressure was 30 psi,drying gas was nitrogen,ion spray voltage was 4 000 V,collision energy was 30 V,and the injection volume was 5 μl. The volumetric method was used for content determi-nation of HgS. RESULTS:TLC spots of amaranth,carmine,erythrosine,acid red 73,808 udan and indirubin were clear and well-separated. 4 batches of 808 udan dyeing were included in the 18 batches of samples,6 batches had non-compliance contents (including 3 batches of 808 udan dyeing). CONCLUSIONS:Dyeing-doped and other quality problems exist in the cinnabaris in markets,which should be noticed.

In gene manipulation, different selectable markers with various linkers are necessary. In order to get selectable markers directly, we constructed from pBlueScript SK(-) a series of particular plasmids, pSKsymKm, pSKsymBle, pSKsymEry, pSKsymHyg and pSKsymGm, each contains Kanamycin, Bleomycin, Erythromycin, Hygromycin or Gentamycin resistance cassette. By restriction enzyme digestion and gel extraction, any of five antibiotic resistance genes with specific ends can be conveniently obtained.
