Advances in bacteria-related pathogenic factors in urinary tract infections / 中华微生物学和免疫学杂志

Urinary tract infections (UTIs) are common, recurrent infections that can range from mild to life-threatening. High recurrence rates of UTIs and increasing antimicrobial resistance may place a greater financial burden on the patients with UTIs. Thus, UTIs is becoming an increasingly serious public health problem. This review summarized how pathogens adhered to and colonized host cells, the important role of bacterial pili in the development of UTIs and the pathogenic mechanisms of different pathogens in UTIs and catheter associated urinary tract infections (CAUTIs). Elucidating the molecular mechanisms of host-pathogen interactions and the pathophysiological consequences of these interactions in UTIs is conducive to further understand the pathogenesis of UTIs.

Study on Determination of Combustion Heat of Matrimony Vine / 中国中医药信息杂志

Objective To determine the colorific value of Matrimory Vine in Qinhai. Method Calorific value of Qinghai matrimony-vine was determined by the method of oxygen bomb type-calorimeter instrument. Results Combustion heat of Qinghai matrimony-vine was 18.36 kJ/g. Conclusion The method is easy and reliable, and its principle is accurate. The data may provide a scientific basis for people’s diet structure and medical use.

Determination of the Content and Extraction of Total Flavonoids in Orange Peel / 中国中医药信息杂志

Objective To extract the flavomids from orange peel and determine the content of total flavmoids in orange peel. Methods The total flavonoids in orange peel were determined by using hesperidine as standard sample and edible alcohol as extraction solvent. Results The total content of flavonids is 19.44 g/kg. Conclusion The method is simple and reproducible. It provides a scientific basis for using orange peel.
