In a pH=0.65―1.5 NaAc-HCl medium, methylene blue（MB） reacts with 12-tungstophosphoric acid （TPA） by virtue of electrostatic attraction and hydrophobic force to form a 3：2 ion-association complex. As a result, the intensities of resonance Rayleigh scattering（RRS）, second-order scattering（SOS） and frequency doubling scatte- ring（FDS） are enhanced greatly. The maximum scattering wavelengths of RRS, SOS and FDS are located at 316, 647 and 311 nm. The increments of scattering intensity（△I） are directly proportional to the concentration of MB in a certain range. The methods exhibited high sensitivity, and the detection limits（3s） for MB are 2.3 ng/mL（RRS method）, 5.6 ng/mL（SOS method） and 6.4 ng/mL（FDS method）, respectively. The effects of coexisting substances have been examined, and the results indicate that the methods have good selectivity. Based on the above researches, a new spectral method for the determination of trace amounts of MB has been developed. It can be applied to the determination of MB in human serum, and the recoveries are 97.5%―105.0%. The results are in good agreement with those obtained by the pharmacopoeia method. In this work, the optimum conditions of the reaction and the influencing factors were investigated. In addition, the reaction mechanism and the reasons of the enhancement of resonance light scattering were discussed.

The increasing demand of high-performance supercapacitors has aroused great interest in developing specific capacitance and energy density. Active carbon （AC） has attracted much attention as a promising electrode material for electric double-layer capacitors （EDLCs）. Here, a facile strategy has been employed to fabricate high-performance EDLCs using the surface-oxygen functionalized active carbon （FAC） as an electrode and 2 M KOH with K3Fe（CN）6 as an electrolyte. In this system, K3Fe（CN）6 was used as a redox additive to enhance the performance of EDLCs. A 38.5% increase in specific capacitance （207.7 F g-1） was achieved compared with the KOH electrolyte without adding K3Fe（CN）G （152.9 F g-1）, due to the synergistic effects between oxygenic functional groups and redox electrolyte. These findings provide an alternative route to improve the performance of EDLCs, which are promising candidates for the broad applications of high-performance supercapacitors.

OBJECTIVE: To estimate the prevalence trend and risk factors for anemia in patients with human immunodeficiency virus(HIV) infection receiving antiretroviral therapy(ART) in rural ***: We conducted cross-sectional studies among the same population in 2010, 2012, and2014, based on data from standard medical record registers. Factors associated with anemia were evaluated using a logistic regression ***: The number of patients with HIV infec-tion included in each cross-sectional study was1456 in 2010, 1531 in 2012, and 1567 in 2014, and the prevalence of anemia was 44.3%, 34.7%, and27.6%, respectively. The prevalence of anemia was lower in female patients in 2010 [odds ratio(OR)0.68; 95% confidence interval(CI) 0.55-0.85]; however, there was no difference by sex in 2012(OR0.90; 95% CI 0.72-1.11) and 2014(OR 1.05; 95% CI0.84-1.32). Patients with a higher level of education had a lower risk of anemia in 2014(OR 0.72; 95% CI0.56-0.92), but there was no difference in 2010(OR1.00; 95% CI 0.79-1.25) and 2012(OR 0.99; 95% CI0.79-1.24). Patients who had received a longer duration of ART had a higher risk of anemia in 2014(OR1.74; 95% CI 1.15-2.64), but there was no difference in 2010 and 2012(P > 0.05). Patients receiving Traditional Chinese Medicine(TCM) therapy had a lower risk of ***: The prevalence of anemia among patients with HIV infection receiving ART decreased between 2010 and 2014 in Henan Province but was still higher than the prevalence in the general population of China. TCM therapy can potentially decrease the risk of anemia among patients with HIV infection.

Objective To evaluate dietary iodine intake and its potential risks among the Chinese population Methods Individual dietary iodine intake was calculated using food consumption data multiplying by iodine concentration in foods, table salt and drinking water, followed by summing, and then compared with the corresponding age-specific reference values, including Upper Intake Level （UL） and Recommended Nutrient Intake （RNI）. Results In areas with water iodine concentration （Wl） lower than 150 ug/L, 80.8% of residents had iodine intake between the RNI and UL, 5.8% higher than UL, and the remaining （13.4%） lower than RNI if iodized salt was consumed. However, in the uniodized salt consumption scenario, only 1.0% of residents between RNI and UL, 1.4% higher than UL, and a large part of residents （97.6%） lower than RNI. In areas with Wl higher than 150 ug/L ,all residents had iodine intake between RNI and UL if iodized salt was consumed, except 10.5% and 24.9% of residents higher than UL in areas with Wl at 150-300 ug/L and higher than 300 ug/L respectively. However, in the uniodized salt consumption scenario, only 1.5% and 1.7% of residents had higher iodine intake than UL respectively. Conclusion The findings suggested that in general, the dietary iodine intake by the Chinese population was appropriate and safe at the present stage. People in areas with WI lower than 150 ug/L were more likely to have iodine deficiency. While people in areas with WI higher than 150 ug/L were more likely to have excessive iodine intake if iodized salt was consumed.

近代基本法确认出版自由为公民的一项基本权利,可是,清末政府、北洋政府、南京国民政府却是施行"管制"+"侵犯"的行政管理模式,不是"消极不作为"而是"积极进取"到公民自由权的范畴,致使公民的出版自由变迁为出版不自由。由此可见,公民的基本权利仅有基本法的确认是不够的,应警惕行政权的滥用并构建有效的制约体制,以便形成行政权对基本权利的良性效力。
