| 1 | Pharmacokinetics after single and multiple intravaginal application of clindamycin phosphate vaginal gel in Chinese female volunteers显示文摘Objective:To investigate the pharmacokinetics of clindamycin phosphate vaginal gel in healthy Chinese female volunteers.Methods:Ten healthy Chinese female volun- teers were intravaginally given with 5.0g of clindamycin phosphate vaginal gel (equivalent to 100mg of clindamycin) once for single dose treatment,and 5.0g,once a day for 3 days,for mul- tiple dose treatment.The serum concentration of clindamycin were determined by HPLC-MS method and its pharmacokinetic parameters of clindamycin were calculated by DAS 1.0 soft- ware.Results:The main pharmacokinetic parameters of clindamycin for single dose and multiple doses were as follows:t_(1/2) were (15.30±2.62) hours and (14.78±2.49) hours,Tmax were (4.88±0.94) hours and (4.70±0.59) hours,Cmax were (38.30±22.77) ng/ml and (44.87±26.71) ng/ml,AUC0_(-∞) were (783.45±351.19) ng·ml^(-1)·h^(-1) and (1015.68±456.95) ng·ml^(-1)·h^(-1),respectively.Conclusion:The Cmax of clindamycin phosphate vaginal gel after a single dose and multiple doses are obviously lower and t_(1,2) are longer than that of clindamycin phosphate oral preparations,which suggests that clindamycin phosphate vaginal gel acts locally and can be slowly absorbed to circulation for systemic actions. | Wang Benjie Li Yunxia Yuan Guiyan Bu Fanlong Guo Ruichen | 2007 | 现代妇产科进展2007，16，2： | 1 |
| 2 | Dietary supplemental coated essential oils and organic acids mixture improves growth performance and gut health along with reduces Salmonella load of broiler chickens infected with Salmonella Enteritidis显示文摘Background Reducing Salmonella infection in broiler chickens by using effective and safe alternatives to antibiotics is vital to provide safer poultry meat and minimize the emergence of drug-resistant Salmonella and the spread of salmonellosis to humans.This study was to first evaluate the protective efficacy of feeding coated essential oils and organic acids mixture(EOA)on broiler chickens infected with Salmonella Enteritidis(S.Enteritidis,SE),and then its action mechanism was further explored.Methods A total of 4801-day-old Arbor Acres male chickens were randomly assigned into five treatments with six replicates,including non-challenged control fed with basal diet(A),SE-challenged control(B),and SE-infected birds fed a basal diet with 300 mg/kg of EOA(BL),500 mg/kg of EOA(BM)and 800 mg/kg of EOA(BH),respectively.All birds on challenged groups were infected with Salmonella Enteritidis on d 13.Results Feeding EOA showed a reversed ability on negative effects caused by SE infection,as evidenced by decreasing the feed conversion rate(FCR)and the ratio of villus height to crypt depth(VH/CD)(P<0.05),obviously decreasing intestinal and internal organs Salmonella load along with increasing cecal butyric acid-producing bacteria abundance(P<0.05).Moreover,supplemental different levels of EOA notably up-regulated claudin-1(CLDN-1),occludin(OCLN),zonula occludens-1(ZO-1),mucin-2(MUC-2),fatty acid binding protein-2(FABP-2),nuclear factor kappa-light-chainenhancer of activated B cells(NF-κB),myeloid differential protein-88(MyD88)and interleukin-6(IL-6)mRNA levels in the ileum of the infected chickens after challenge,whereas down-regulated toll-like receptor-4(TLR-4)mRNA levels(P<0.05).Linear discriminant analysis combined effect size measurements analysis(LEfSe)showed that the relative abundance of g_Butyricicoccus,g_Anaerotruncus and g_unclassified_f_Bacillaceae significantly was enriched in infected birds given EOA.Also,phylogenetic investigation of communities by reconstruction of unobserved states(PICRUSt)analysis showed that alpha-linolenic acid metabolism,fatty acid metabolism and biosynthesis of unsaturated fatty acids were significantly enriched in the EOA group.Conclusion Our data suggest that the essential oils and organic acids mixture can be used as an effective strategy to ameliorate and alleviate Salmonella Enteritidis infection in broilers. | Zeqiong Hu Lin Liu Fangshen Guo Jia Huang Jianing Qiao Ruichen Bi Jinyu Huang Kaichen Zhang Yuming Guo Zhong Wang | 2023 | Journal of Animal Science and Biotechnology2023，14，6： | 0 |
| 3 | Progress of organic,inorganic redox flow battery and mechanism of electrode reaction显示文摘With the deployment of renewable energy and the increasing demand for power grid modernization,redox flow battery has attracted a lot of research interest in recent years.Among the available energy storage technologies,the redox flow battery is considered the most promising candidate battery due to its unlimited capacity,design flexibility,and safety.In this review,we summarize the latest progress and improvement strategies of common inorganic redox flow batteries,such as vanadium redox flow batteries,iron-chromium redox flow batteries,and zinc-based redox flow batteries,including electrolyte,membrane,electrode,structure design,etc.In addition,we introduce the latest progress in aqueous and non-aqueous organic redox flow batteries.We also focus on the modification mechanism,optimization design,improvement strategy,and modeling method of the redox flow battery reaction.Finally,this review presents a brief summary,challenges,and perspectives of the redox flow battery. | Yinping Liu Yingchun Niu Xiangcheng Ouyang Chao Guo Peiyu Han Ruichen Zhou Ali Heydari Yang Zhou Olli Ikkala Glazkov Artem Tigranovich Chunming Xu Quan Xu | 2023 | Nano Research Energy2023，2，4： | 0 |
| 4 | Construction of high stability indium gallium zinc oxide transistor biosensors for reliable detection of bladder cancer-associated microRNA显示文摘Bladder cancer is the most common malignant tumours with high morbidity, mortality and recurrence.However, currently developed detection methods for bladder cancer-associated urine biomarkers are hindered by their extremely low abundance. Hence, the exploration of a highly sensitive and selective approach for the detection of trace bladder cancer-associated biomarkers in human urine is of vital importance for the diagnosis of bladder cancer. Herein, we developed a highly reliable indium gallium zinc oxide field effect transistor(IGZO FET) biosensor for the detection of bladder cancer-related biomarker micro RNA. The single-stranded DNA-functionalized IGZO FET biosensors exhibit high sensing reproducibility and stability with an ultralow detection limit of 19.8 amol/L. The device could also be used for quantitative detection of trace micro RNA in human urine samples and can effectively distinguish bladder cancer patients from healthy donors. The development of high performance IGZO FET biosensors presents new opportunities for the achievement of early-stage diagnosis of bladder cancer. | Jing Guo Ruichen Shen Xuejie Shen Bo Zeng Nianjun Yang Huageng Liang Yanbing Yang Quan Yuan | 2022 | Chinese Chemical Letters2022，33，2： | 0 |
