Objective To investigate the effect of mechanical vibration sputum expectoration in the adjuvant treatment of stroke-associated pneumonia. Methods Totally 60 patients with stroke-associated pneumonia were divided into control group (n=30)and study group(n=30) according to the arrival sequences of hospital admission. All patients received anti-infective therapy for stroke-associated pneumonia. The routine hand-assisted percussion on the back was adopted in the control group, while the mechanical vibration sputum expectoration was carried out in the study group. The clinical symptoms and clinical pulmonary infection scores of the two groups were observed at one week after intervention. Results The overall response rate of treatment was 96. 67%(29/30)in the study group, which was higher than 80. 00%(24/30)in the control group (P＜0. 05). Patients in the study group had a higher volume of sputum expectoration and shorter time to moist rale disappear compared with those in the control group (P＜0. 01).

The development of deep-sea exploration technology is of great significance to the study of global environmental changes, the exploration of life origin, the search for seabed resources, and the assessment of marine pollution, and has become an important direction of today's scientific and technological development. Traditional analytical techniques require seawater to be sampled, stored, and then transferred to a laboratory for analyzing, which not only consume time, but also result in biased results. The in situ detection technology can realize long-term, real-time continuous detection, which can solve the problem of sample storage and improve the detection accuracy. Mass spectrometry has abilities to qualitatively and quantitatively analyze low-concentration substances, which is suitable for in situ analysis. But compared with ground-based applications, the enormous pressure of the deep ocean brings challenges to the analysis of mass spectrometry in the ocean. Mass spectrometry instruments need to work in a high vacuum environment, which require that the sampling system must be able to withstand the pressure difference between the high-pressure liquid and the high vacuum inside the instrument. In order to realize the application of mass spectrometry detection technology in deep-sea exploration, a membrane sampling device capable of withstanding ultra-high water pressure was developed based on the injection technology of volatile organic compounds and dissolved gases in high-pressure liquid environment. The device processes porous sintered rods, vacuum plugs and sampling stainless steel tubes into an integrated sampling structure through a welding process, then coated a hydrophobic membrane, and used ultra-high vacuum sealant to fix and seal the membrane and sampling structure. Therefore, it is ensured that it has sufficient mechanical structural strength, so that the sample injection device can work directly under ultra-high pressure for a long time. A high pressure test environment was constructed by using a high performance liquid chromatography pump and a back pressure regulator, and the pressure resistance test of the ultra-high pressure membrane sampling device was carried out. The test results showed that the device had worked for more than half a month under water pressure of 40 MPa. The sampling device was applied to the online mass spectrometry system, and the sampling efficiency of benzene series and other substances under different pressures, temperatures and flow rates was tested.

A parallel calculation and symmetry property of the Jacobian matrix deduced from a ventilation network is adopted in this study to enhance the reliability and the performance of software on calculating Coalmine’s ventilation network. Hie theory of solving Coalmine’s ventilation network by using Newtown method is presented in some details, and then the symmetry characteristic of the Jacobian matrix of a ventilation network is illustrated. A LDLT decomposition method is put forward to solve the corrected value of flow rate in a circuit, which can save a lot of time during each iteration. To take the most advantages of a multi-CPU computer, a parallel model is employed to solve the Jacobian matrix and the equations of corrected values in circuits of a ventilation network. This parallel model is achieved using the technology of multi-threads in VC language, whose validity and performance are verified by running it in two ventilation network samples.
