Five kinds of traditional flower Chinese medicine powders (TFCMD) were identified using tuneable liquid spectral imaging instrument, to discuss the application range and advantages of spectral imaging technology in Chinese medicine identification and analysis field. The testing system is the liquid crystal multispectral imaging system designed by ourselves. All the tests are standard samples supplied by National Institute for Drug Control. The spectral cubes of Campsis grandiflora, Carthamus tinctorius, Albizzia julibrissin, Dendranthema morifolium, and Dendranthema indicum were captured, and then the normalized characteristic spectral curves of them were picked up. The spectral resolution is 5 nm, and the spectral range is 400 nm - 650 nm. The result shows that different TFCMD has different normalized characteristic fluorescence spectral curve. Spectral imaging technology can be used to identify TFCMD, and the testing course is convenient, quick, noninvasive and without pre-treatment.

The identification and quality evaluation of Flos carthami were studied using tunable liquid spectral imaging instrument, to discuss the application range and advantages of spectral imaging technology in Chinese medicine identification and quality control field. The Flos carthami was indentified by extracting the normalized characteristic spectral curves of Flos carthami, Crocus sativus and Dendranthema morifolium, which were standard samples supplied by National Institute for Drug Control. The qualities of Flos carthamies collecting from different pharmacies were evaluated by extracting their normalized characteristic spectral curves. The imaging spectrum testing system was designed independently. The spectral resolution was 5 nm, and the spectral range was from 400 nm to 680 nm. The results showed that the normalized characteristic spectral curve of Flos carthami was significantly different from those of Crocus sativus’ and Dendranthema morifolium’s, and the fluorescence intensity of Flos carthami from different commercial sources were different. Spectral imaging technology could be used to identify and evaluate Flos carthami, and operation method was rapid, convenient and non-destructive.

Objective: The purpose of this study was to evaluate the difference in alcohol use between urban and rural students of Inner Mongolia Medical University. Methods: A cross-sectional census was conducted on medical students on campus in 2013. We use multivariate logistic regression models to assess the factors associated with alcohol use. We further use chi-square test assess on differences in alcohol use between urban and rural people among significance factors in logistic regression models. Results: The prevalence of alcohol use among students in rural area was higher than that in urban area (p = 0.016). Alcohol use was associated with Gender, monthly expenses, residence, ethnic and faculty. The odds of alcohol use for Mongolia students were 1.139 times higher than that for Han students. The prevalence of alcohol consumption among students from pharmacy or Traditional Chinese Medicine and Mongolian Medicine faculties in rural area was higher than that among student in urban area (p = 0.03;p = 0.001). The prevalence of alcohol use among female students in rural area was higher than that among female students in urban area (p < 0.043). The proportion of alcohol use among students with <600 in rural area was higher than that among students in urban area (p < 0.001). Conclusion: Considering the differences in the prevalence of alcohol use between rural area and urban area, university administrators aiming at students from various regions develop various approaches.

Objective: The study aimed to assess the characteristics of pancreatic cancer deaths and the relationship between socio-demographic status and mortality risk of pancreatic cancer in Inner Mongolia. Method: We obtained our data for 2008-2014 from the Death Registry System of Inner Mongolia. We calculated the mortality rate, potential years of life lost (PYLL) and average years of life lost (AYLL) for men and women. We collected socio-demographic characteristics including education level, ethnicity, region, and occupation. Logistic regression models were employed to analyze risk factors of pancreatic cancer. Results: The average mortality rate of pancreatic cancer was 4.42/100,000 in Inner Mongolia during 2008 to 2014. Mortality rate in men was higher in all age groups compared with those in women. The highest mortality rate was 1.3 times than the lowest mortality rate for men and 1.6 times for women during seven years. Average AYLL in women were more than 3.4 years compared with that in men. PYLLR in women was fluctuated from 0.41 to 0.63 per thousand during 2008 to 2014. In eastern region, no occupation and high education level had a higher risk of pancreatic cancer. Conclusion: In Inner Mongolia, the mortality rate associated with pancreatic cancer was higher in men compared with in women. More than 65 years old groups had high death risk for pancreatic cancer. Average years of life lost for women were significantly higher than that for men. We should pay more attention to the older men.

目前乳酸菌发酵产细菌素的含量较低,因此优化产细菌素的发酵条件是最直接的方式。对分离自内蒙古传统干酪的植物乳杆菌NMGL2的抗生素药敏性、溶血性以及全基因组序列进行分析,结果表明该菌株无明显毒力作用,不携带高毒力因子,抗性基因无转移风险。对植物乳杆菌NMGL2产细菌素的发酵条件进行研究,以金黄色葡萄球菌为指示菌,通过单因素实验以及基于接种率、发酵起始pH值、培养温度3个因素的Box-Behnken法三因素三水平的响应面分析,确定植物乳杆菌NMGL2产细菌素的最佳发酵条件是:发酵起始pH 7.0,接种率1.3%,培养温度37℃。验证试验结果显示在此优化发酵条件下获得对指示菌(金黄色葡萄球菌)的抑菌圈直径为13.8 mm,与模型预测值(13.4 mm)基本吻合,拟合率达到96.64%,证明该模型可靠有效。本研究为植物乳杆菌NMGL2发酵生产细菌素及其应用提供了技术参考。
