The addition of long-term noninvasive positive pressure ventilation (NPPV) to a pulmonary rehabilitation (PR) program in stable patients with advanced chronic obstructive pulmonary disease (COPD) can enhance the effects of PR, continuely improve exercise tolerance and dyspnea, stabilize pulmonary function, enhance health-related quality of life. Moreover, it maybe improve the prognosis of the patients with COPD. This article introduced the implement of the combination of PR and NPPV in stable patients with advanced COPD.

Objective: To optimize the allocation scheme of military medical equipments based on the characteristics of modern war and the progression of the military medical equipment of People's Liberation Army (PLA). Methods: Aiming to optimize the allocation of military medical equipment, we designed the integrated framework of the allocation system and analyzed the need of optimized allocation. Using the linear programming and queuing theory, we established the optimized allocation models for both medical treatment equipments and evacuation equipments. Results: Based on the health service characteristics of military medical equipments, the optimized allocation models for medical treatment equipments and evacuation equipments were successfully established. The application of the established models was studied in the medical service station of the division level. Conclusion: The optimized allocation scheme of military medical equipment has been proposed in the present study, which provides evidence for decision-making on the future development of military medical equipments of PLA.

Objective To establish the quality standard of Fufang-Shiwu-Zhixue powder. Methods The microscopical identification was adopted to analyze charred typha pollen and cuttlebone. TLC was used to identity rhubarb and radix notoginseng. UV-HPLC was used to determine the contents of notoginsenosides R1, ginsenosides Rg 1, ginsenosides Rb1. Results Microscopic identifications shower the characteristics of harred typha pollen and cuttlebone. The identified characteristics of rhubarb and radix notoginseng by TLC were distinct and the spots were clear. Notoginsenosides R1, ginsenosides Rg 1, ginsenosides Rb1 showed good linearity in the range of 0.16-1.58 μg (r=0.9998), 0.58-5.81 μg (r=0.9999), 0.33-3.29 μg (r=1.0000), respervtively.The average recoveries were 98.51% (RSD=1.81%), 97.80% (RSD=2.04%), 98.22%(RSD=1.45%). Conclusions The method is accurate, simple and repeatable, which could be used for the quality control of Fufang-Shiwu-Zhixue powder.

Objective To establish the quality control ofBaiduyin syrup.Methods The TLC was used to identity Radix paeoniae rubra, Radix Scutellariae. The quantitative determination of baicalin and buddleoside was completed by HPLC.Results The spots on TLC plates were distinct and high resolution. Compared with the negative samples, the contrast medicinal materials or control products showed that there were no spots of the same color in the corresponding position. The linear ranges of baicalin and buddleoside were 0.2179-2.1790 μg (r2=0.999 9), 0.1319-1.3190 μg (r2=0.999 7). TheRSD were 1.51% and 2.01%. Conclusions The established quality control method is simple, accurate and reproducible, which can be used for the quality control ofBaiduyin syrup.

Objective:To study the effects of BMP-7 gene transfected bone marrow mesenchymal stem cells(MSCs)on callus acceleration in rat mandibular distraction osteogenesis.Methods:Forty-eight adult male SD rats were randomly divided into experimental and control groups.MSCs were obtained from individual rat and transfected by pEGF-P-BMP7 for the 24 experimental rats and by the empty vector pEGFP-N1 for the 24 control rats.The rats were underwent right mandibular distraction.1?106/100 ?l BMP-7 gene transfected cells in 10 ?l of normal saline were injected into the distraction gap in each experimental rat,while the same number of empty vector transfected cells in each control rat.The distracted mandibles were harvested 2,4,and 8 weeks respectively after cell injection and evaluated by radiological,histological and histomorphometric analysis.Results:Radiological and histological examinations showed that more new bone was formed in experimental group than in control.Histomorphometric analysis also demonstrated that both new bone volume(NBV1 and NBV2)and the thickness of new trabeculae(TNT)were significantly higher in experimental rats than those in control(P

There is significant evidence to show that many neurosurgical patients with hyponatremia, who were previously diagnosed with syndrome of inappropriate antidiuretic hormone secretion(SIADH), actually have cerebral salt wasting syndrome(CSWS). The critical difference between SIADH and CSWS is that CSWS involves renal salt loss leading to hyponatremia and volume loss, whereas SIADH is a euvolemic or hypervolemic condition. The primary treatment for CSWS is water and salt replacement. The mechanisms underlying CSWS are not understood but may involve ANP or other natriuretic factors and direct neural influence on renal function.

Objective To explore some characters of auditory steady-state responses (ASSR) to multiple simultaneous stimuli in a sample of normal-hearing adults.Methods The ASSR to multiple simultaneous stimuli were recorded in a sample of 32 normal-hearing adults (64 ears). Simultaneous carrier tones (0.5, 1, 2 and 4 kHz), modulated in amplitude at different rate of 77, 85,93, 101 Hz for left ear and 79, 87, 95, 103 Hz for right ear, were presented binaurally by the insert phones. For each subject the response thresholds (RTHs) at 0.5, 1, 2 and 4 kHz were determined automatically and compared with the corresponding behavioral thresholds (BTHs).Results ①In the normal-hearing adults, RTHs were on average between 7～19 dB above the BTHs.②2-way repeated measures ANOVA (ear?carrier frequencies) showed significant main effect between carrier frequencies on RTH ( F =31.254; ? 3,179; P =0.000). Post Hoc analysis indicated that this effect was due to the highest threshold found at 0.5 kHz. The test showed no significant difference of threshold between left ear and right ear ( F =1.942; ? 1,179; P =0.165). ③Taking 60 dB SPL as analysis level, 2-way repeated measures ANOVA (gender?carrier frequencies) revealed significant difference of amplitude between male and female( F =16.490; ? 1,175; P =0.000); and difference of amplitude between carrier frequencies ( F =2.948; ?3, 175; P =0.034).④The average testing time was 61 minutes for male and 69 minutes for female. Independent t-test showed statistical significance within sex.⑤Two- way ANOVA (state?frequency)showed that background EEG noise were significantly higher in awake than that in sleep ( F =152.511; P =0.000). There were no appreciable significance in background noise among frequencies. Conclusion The ASSR to multiple simultaneous stimuli was proven to be a frequency specific, objective and valid technique for threshold estimation at least for normal-hearing adults. Issues concern ing clinical use were discussed.
