This paper introduces the structure and main features of TMS320VC5416, the 16-bit fixed-point DSP of TI company. It discusses the principle and scheme of the adaptive filter using LMS and FX-LMS algorithm to distill voice form noises and to cancel noises with this kind of DSP. It also describes the problems during the process of designing the hardware and software.

This paper develops a USB signal acquisition card to introduce ECG signal into the computer for display, storagee and analysis. Such aspects get involved in as the acquisition, amplification, filter and AD conversion as well as the principle and structure of USB transmission circuit. MSP430 series of SCMs of TI Corp and SPCP825 chip of SunPlus Corp are adopted as the micro-controller and USB transmission chip respectively.

A system adapted for depot management in hospital based on RFID technology is introduced. With resolution of RFID from PHILIPS and RF transmission from Nordic VLSI Norway, the storage of medical materials and medical equipments can be identified, labeled and statistically controlled accurately and expediently. The system can not only save a mass of work force, but also improve work efficiency.

A 29-year-old man visited Zhongshan Hospital, Fudan University in December 2021. The patient presented with recurrent coughing, sputum, and wheezing, high level of serum total IgE, positive aspergillus fumigatus-specific IgE and extremely severe mixed ventilatory dysfunction. These features and thoracic CT results scan showed bronchiectasis and allergic bronchopulmonary aspergillosis. In consideration of his clinical characteristics, including low levels of fractional exhaled nitric oxide (FeNO), and nasal nitric oxide (nNO), persistent cough after birth, consanguineous marriage of his parents, etc. we ratiocinated a possibility of hereditary diseases, especially primary ciliary dyskinesia (PCD). From this perspective, whole exome sequencing (WES) was performed and the diagnosis of PCD was ultimately confirmed.
