We reported on a new amperometric sensor for the sensitive and selective determination of iodate in table salt. The iodate sensor was constructed by the integration of a novel nanocomposite which was made from 9,10-phenanthrenequinone（PQ） and graphene（GP） with a glassy carbon electrode（GCE）. The synthesized graphene and the nanocomposite were well characterized by X-ray diffraction（XRD）, transmission electron microscopy（TEM）, Fourier transform infrared（FTIR） spectroscopy and Raman spectroscopy. We fully studied the electrochemical beha- vior and kinetic characteristics of the PQ/GP nanocomposite at GCE. The PQ/GP electrode shows a good electrochemical catalytic activity towards the reduction of iodate, which makes itself a sensitive and selective electrochemical sensor for iodate. The iodate sensor displays a high sensitivity（1.04 ***.L-1）, a low detection limit（1.0X 10-8 mol/L）, a rapid response（less than 2 s）, and a broad linear range（from 5.0X 10-8 mol/L to 6.0X 10-3 mol/L ）. In addition, the sensor is interference free. The practical application of the proposed sensor was tested by the detection of iodate in table salt.

AIM： To investigate the value and prospect of RT-PCR in detecting micrometastasis in regional lymph nodes of gastric cancer. METHODS： Histopathology was used and K19 mRNA expression was detected by RT-PCR in tumor tissues and lymph nodes from gastric cancer patients undergoing radical resection of gastric carcinoma. RESULTS： K19 mRNA was expressed in all tumor specimens of 30 cases; of the 126 lymph nodes, 26 were histopathologically positive （20.6%）, and 42 positive （33.3%） by RT-PCR. Amplification fragments of 460 and 540 bp were shown in all the tumor tissues and metastatic lymph nodes after K19 and β-actin RT-PCR, while only a 540 bp fragment appeared in the lymph nodes of non-tumor patients. CONCLUSION： K19 mRNA RT-PCR is sensitive and specific in testing micrometastasis in regional lymph nodes of gastric cancer, and it is superior to routine histopathology.

This study was conducted to resolve the problems of water conservation of sandy soil in desertification areas. The surface of soil particles was modified by molecules of natural Japanese wax through some specially screened surfactant. The modified particles were then well sprayed onto the sand, which was placed in an artificial climate box with simulating desert environment, to form a soil film with effect of suppressing water and gas-permeability. Structure of soil film was analyzed by means of X-ray diftYaction （XRD） and infrared spectrometry （IR）. And its mechanism of water inhibition was illustrated with DSC and TG curves. Its influence on grass-planting was tested through the instruments of water detector. The results show that sorbitol anhydride stearate （ Span 80） could well disperse the Japanese wax and make it combine with the clay which is also dispersed. The pores among soil particles grew smaller and turned from hydrophilic into hydrophobic, in which way resistance to water penetrating through the film was increased. Experimental grass grows normally on sandy soil with the soil film in the artificial desert climate box, indicating that the soil particles modified with Japanese wax is an effective method to inhibit water evaporation.

抗战时期,食盐在陕甘宁边区经济中占有重要地位。'皖南事变'前,边区财政来源主要是外援,政府只征少量的盐税,故食盐走私并不严重;'皖南事变'后,外援断绝,随着边区政府对盐税的倚重及管理的加强,食盐走私逐渐泛滥。走私形式花样百出,不一而足,走私原因也是多方面的,其对边区所造成的政治经济影响不可忽视。鉴于此,边区政府采取多种措施治理打击食盐走私,诸如健全缉私机构,颁布相应的法规制度,发动群众力量缉私等。在边区政府的治理及严厉打击下,食盐缉私取得了一定成效,但并未销声匿迹。

[ Objective] To provide a theoretical basis for improving reproductive efficiency of domestic beef cattle in Jilin of China. [ Method] China Red Steppe cattle, Yanbian yellow cattle and Simmental cattle in Jilin Province were used for detection. The levels of progesterone （P4）, estradiol （ E2 ）, follicle-stimulating hormone （FSH） and luteinizing hormone （LH） in serum and urine during estrus cycle were determined. [ Result] The levels of P4 and E2 were significantly different between pregnant cattle and non-pregnant cattle on Day 21 post estrus （ P 〈 0.01 ）. The level of LH on estrus day was significantly different from that on the other days of estrus cycle （ P 〈 0.05）. [ Conclusion] It is feasible to detect P4 level for diagnosis of estrus and eady pregnancy in beef cattle.

目的了解甘肃省普通居民自行购买非处方药品情况及相关知识、信念、行为,为制定非处方药品购买干预措施提供依据。方法采用分层整群抽样方法,随机选取甘肃省各市州常住居民为研究对象,于2017年7—12月进行入户调查,收回有效问卷3 111份。采用Epi Data 3.10建立数据库录入数据、SPSS 16.0软件描述分析居民自行购买非处方药品情况及相关知识、信念、行为发生率。结果近一年有自我用药行为的居民2 541人(81.8%);居民自行服用的药物主要来自正规药店(66.9%)和医院(43.6%),来自私人诊所占28.5%,凭处方到药店购买占16.1%,亲朋赠送的占15.2%。自行购药主要原因为疾病不严重(60.1%);城镇、男性居民及医护人员更信赖药师;家庭人口数、是否患慢性病对非处方药品认知存在差异(P <0.05);农村居民选药时倾向考虑药品价格,起居规律居民、医护人员倾向考虑药品不良反应,慢性病患者倾向考虑速效高效。结论甘肃省居民对非处方药品认知有限,不能理性消费药品,需特别关注农村居民、老年人、慢性病患者、女性等特殊群体购药理念,进一步规范药店布局,强化药师业务能力与职业素养。
