Advance of the interventional treatment for chylothorax / 中华胸心血管外科杂志

Chylothorax is one of the complications of surgery and lymphatic diseases. The incidence rate of chylothorax has been increasing in recent years. X-ray-guided interventional therapy is a new method for treating chylothorax, and its curative effect is no less than the traditional surgical treatment. Based on discussing the aetiology and diagnosis of chylothorax, this paper briefly summarizes the application progress of X-ray-guided interventional therapy for chylothorax to provide further reference and a basis for clinical practice.

Detection of Chemical Warfare Agent Simulants by UV Photoionization High-Field Asymmetric Ion Mobility Spectrometry / 分析化学

Accurate diffusion was used to get low concentrations samples, and then the samples were detected by UV photoionization high-field asymmetric ion Mobility spectrometry ( UV-FAIMS ) . The samples were chemical warfare agent simulants ( CWAS) vapor:dimethyl methylphosphonate ( DMMP ) , dimethyl sulfoxide ( DMSO) , tributyl phosphate ( TBP ) and dimethyl sulfoxide ( DMF) . The results of FAIMS spectra data were analyzed by separation of spectra at different dispersion voltage ( DV ) and compensation voltage ( CV ) . A two-dimensional spectrum of α2 and α4 of CWAS was established. It was shown that FAIMS could identify CWAS well and have a good sensitivity. Take DMMP as a example, the detection limit was better than 0. 55 μg/L.

Technology and prospects of noninvasive blood glucose measurement / 生物医学工程学杂志

Non-invasive (NI) blood glucose measurement is a new method, this article deals with current researches and analyzes the advantages and shortages of different measurement methods, including electrochemical process and Optical methods (transmission, polarimetry and back scattering). Then, the technology of near-infrared spectra is emphasized in the analysis. Finally, the problem and technical analysis of non-invasive (NI) blood glucose measurement at the present time are discussed. We preliminarily aim at the method of NI blood glucose determination and the original concept of measuring apparatus, including the choice of incident light wavelength, determination of receiver point, establishment of the optical model of biological tissue, and apparatus design.

Filariasis Elimination in Zoucheng City of Shandong Province: Measures and Effect / 中国寄生虫学与寄生虫病杂志

Zoucheng was a high endemic area of bancrotian filariasis with Culex pipiens pallens as the principal transmitting vector. Transmissiom of the disease was interrupted in 1981. Epidemiological surveillance has been then carried out. After 1989, parasitological and immunological examinations were conducted for those cases previously with and without microfilaremia, entomological surveillance was also carried out. Results showed that the antibody level in inhabitants has been at normal level, and no infection has been found in mosquitoes.
