| 1 | Influence of physical properties of carrier on the performance of dry powder inhalers显示文摘Dry powder inhalers(DPIs) offer distinct advantages as a means of pulmonary drug delivery and have attracted much attention in the field of pharmaceutical science. DPIs commonly contain micronized drug particles which, because of their cohesiveness and strong propensity to aggregate, have poor aerosolization performance. Thus carriers with a larger particle size are added to address this problem. However, the performance of DPIs is profoundly influenced by the physical properties of the carrier, particularly their particle size, morphology/shape and surface roughness. Because these factors are interdependent, it is difficult to completely understand how they individually influence DPI performance.The purpose of this review is to summarize and illuminate how these factors affect drug–carrier interaction and influence the performance of DPIs. | Tingting Peng Shiqi Lin Boyi Niu Xinyi Wang Ying Huang Xuejuan Zhang Ge Li Xin Pan Chuanbin Wu | 2016 | Acta Pharmaceutica Sinica B2016，6，4： | 8 |
| 2 | Solid lipid dispersion of calcitriol with enhanced dissolution and stability显示文摘Solid dispersion of calcitriol with lipophilic surfactants and triglycerides was developed by melt-mixing method to modify the release and enhance stability of the drug.The solid dispersions were characterized by differential scanning calorimetry(DSC),hot stage polarized optical microscopy(HSPM),infrared spectroscopy(FTIR)and stability studies.The solid dispersion significantly enhanced the stability of calcitriol,which could be attributed to the high antioxidant activity of the solid lipid dispersion.The rapid dissolution rate from the solid dispersion was attributed to the amorphous or solid solution state of drug with improved specific surface area and wettability than the drug crystals.Therefore,solid dispersion of calcitriol with D-a-tocopheryl polyethylene glycol 1000 succinate(TPGS)offers a good approach to modify the release and enhance stability of calcitriol.The influence of lipophilic solid dispersion on drug bioavailability needs further investigation. | Ting Yuan Lingzhen Qin Zhouhua Wang Jinyuan Nie Zhefei Guo Ge Li Chuanbin Wu | 2013 | Asian Journal of Pharmaceutical Sciences2013，8，1： | 2 |
| 3 | Studies on the spray dried lactose as carrier for dry powder inhalation显示文摘The purpose of this study was to investigate the spray dried lactose as carrier for dry powder inhalation(DPI).The lactose particles were prepared by spray drying,then the particle size,shape and crystal form were characterized by laser diffraction,scanning electron microscopy(SEM),X-ray diffraction(XRD)and differential scanning calorimetry(DSC).The spray dried lactose particles were spherical and amorphous,but would transfer to crystal form when storage humidity was above 32%.Thus,the humidity of the storage environment should be controlled below 30%strictly in order to maintain the amorphous nature of spray dried lactose which is a great benefit to DPI development. | Linna Wu Xu Miao Ziyun Shan Ying Huang Lu Li Xin Pan Qinghe Yao Ge Li Chuanbin Wu | 2014 | Asian Journal of Pharmaceutical Sciences2014，9，6： | 1 |

| 5 | Detection of T-wave Alternans in ECG Signals Using FRFT and Tensor Decomposition显示文摘T-wave alternans(TWA)refers to the periodic beat-to-beat variation in the amplitude of T-wave in the electrocardiogram(ECG)signal in an ABAB-pattern.TWA has been proven to be a very important indicator of malignant arrhythmia risk stratification.A new method to detect TWA by combining fractional Fourier transform(FRFT)and tensor decomposition is proposed.First,the T-wave vector is extracted from the ECG of each heartbeat,and its FRFT amplitudes at multiple orders are arranged to form a T-wave matrix.Then,a third-order tensor is composed of T-wave matrices of several consecutive heart beats.After tensor decomposition,projection matrices are obtained in three dimensions.The complexity of the projection matrix is measured by Shannon entropy to obtain feature vector to detect the presence of TWA.Results show that the sensitivity,specificity,and accuracy of the algorithm on the MIT-BIH database are 91.16%,94.25%,and 92.68%,respectively.This method effectively utilizes the fractional domain information of ECG,and shows the promising potential of the FRFT in ECG signal processing. | Chuanbin Ge Shuli Zhao Yi Xin | 2021 | Journal of Beijing Institute of Technology2021，30，3： | 0 |
