Objective: To study the relationship between slow coronary lfow (SCF) and coronary microcirculatory dysfunction in relevant patients and to explore the risk factors for SCF development. Methods: Our research was conducted in 2 groups: SCF group, the patients with coronary angiography conifrmed diagnosis and Control group, the subjects with normal coronary lfow.n=32 in each group. The general information, blood levels of biochemical indicators, hs-CRP levels, TIMI lfow frame and the index of microcirculatory resistance (IMR) were examined, their relationships to SCF were analyzed. Results: Compared with Control group, the patients in SCF group showed the lower levels of HLL-C (1.57 ± 0.38) mmol/L vs (1.62 ± 0.43) mmol/L and Apo-A1 (1.41 ± 0.31) mmol/L vs (1.57 ± 0.38) mmol/L, while higher level of hs-CRP (3.63 ± 1.67) μg/mL vs (1.74 ± 0.75) μg/mL; SCF groups had increased IMR (29.28 ± 7.68) vs (24.94 ± 6.67), all P<0.05. IMR was positively related to TIMI lfow frame (r=0.766, P=0.019) and hs-CRP (r=0.565, P=0.000). Conclusion:①Microcirculatory dysfunction was related to SCF.②Inlfammatory reaction, decreased blood levels of HDL-C and Apo-A1 might be involved in pathological process of SCF.

In light of the spread and establishment of hospital information systems in the Shanghai area,the paper argues that government departments in charge ought to start in good time research on digitalized hospitals so as to better standardize how hospitals should promote in an active and steady manner a new round of development of hospital information systems.It also gives a detailed account of the content and methods of research on digitalized hospitals as well as development strategies in Shanghai.

OBJECTIVE:To evaluate the stability of tinidazole and cefotaxime sodium mixed in infusion fluid at 4℃,25℃ and 37℃ for 24 hours.METHODS:Tinidazole and cefotaxime sodium were determined by RP-HPLC method and the pH of solution was determined with a pH meter.RESULTS:There were no significant changes in pH of the solution at 4℃,25℃ and 37℃ for 24 hours; Along with the duration, there were significant changes in the appearance of solution and the concentrations of tinidazole and cefotaxime sodium.UV absorption curve of tinidazole and cefotaxime mixed solution revealed small changes at 4℃ for 6 hours, 25℃ for 2 hours and 37℃ for 1 hour, showing a new peak.CONCLUSION: Tinidazole and cefotaxime sodium mixed in infusion fluid were stable at 4℃ for 6 hours,25℃ for 2 hours and 37℃ for 1 hour.

Objective:To explore the module of the construction and application of medical first-aid at the door of the space capsule and the air evacuation.Methods:According to the purpose, principle, and method set by the module, it was divided into two sub-modules: medical first-aid at the door of the space capsule and the air evacuation. During the comprehensive first-aid training, independent training and combined training were carried out respectively according to different mission stages of launch and recovery and different recovery terrain. Meanwhile, research was performed to ensure that medical carrying equipment was lightweight, modular, and portable, and the efficiency of modularization construction was tested in the comprehensive training.Results:The module of medical first-aid at the door of the space capsule and the air evacuation obviously shortened the rescuing time during the comprehensive training, the saving effect was remarkable, and the overall saving efficiency was significantly improved.Conclusions:The module of medical first-aid at the door of the space capsule and the air evacuation meet the requirements that the emergency support system of aerospace medicine should function on an immediate basis, ensuring accurate treatment and air evacuation without any delay, so that to achieve the aim of aerospace medicare.

Objective:To review the characteristics and coping strategies of the rescue and landing medical support mission of Shenzhou-14 manned spacecraft.Methods:The characteristics of rescue and landing medical support mission of Shenzhou-14 manned spacecraft was analyzed, and the coping strategies and experience were discussed.Results:(1) The characteristics of rescue and landing medical support mission of Shenzhou-14 manned spacecraft included: long time in space station and high-intensity space missions; high-density space medical support mission in short term; special environmental factors in severe cold night; complex terrain of landing site; and the young medical support team. (2) The main coping strategies of rescue and landing medical support mission of Shenzhou-14 manned spacecraft included: strengthened the organization and leadership and improved the training model; reinforcement learning the medical treatment plan and strengthened the medical rescue skills training; optimized the carrying equipment and added the heat preservation and lighting measures; improved the medical rescue process and perfected the emergency plan; emphasized on the scientific research as important as mission; and strengthened the physical exercise and cold resistance exercise.Conclusions:The characteristics and coping strategies of rescue and landing medical support mission of Shenzhou-14 manned spacecraft are summarized to provide the experience for space medical rescue and offer the support for China's manned space industry.
