1.Discussion on Life Education of Traditional Chinese Medicine Based on Traditional Philosophy of Life
Chinese Medical Ethics 2017;30(2):191-194
The humanistic thinking of life philosophy of traditional Chinese medicine (TCM) observed inlife activities is different from western theories and methods,which is more about life experience and feeling and rich in practical significance.The life philosophy of TCM is also different from traditional Chinese culture.The intuitive feeling of life is one of the main characteristics of life philosophy of TCM.Students of TCM soak in traditional Chinese medicine culture and are influenced by the thinking of real life caused by the care of realbody in TCM.Chinese medicine education should fully mobilize the tacit knowledge of life education in TCM,play excellent tradition of Chinese traditional life philosophy,and cultivate the life moral quality in students of TCM.

Objective It has been shown that ketamine and magnesium used in combination provide more effective analgesia than either drug alone. The purpose of this study was to investigate the effects and interaction of the two drugs on recombinantly expressed NMDA receptors. Methods Xenopus oocytes expressing NR1/NR2A or NR1/NR2B glutamate receptors were stimulated with glutamate/glycine and studied at a holding potential of -70mV using two electrode voltage clamp. The effects of magnesium and s ( + )-ketamine alone or in combination on NMDA signaling were determined. Results Magnesium and s( + )-ketamine alone inhibited NMDA receptors non-competitively. IC50s of magnesium were (4.2 ± 1.2)×10-4mol/L and (6.3 ± 2.4) × 10-4 mol/L on NR1/NR2A and NR1/NR2B, while IC50s of s( + )-ketamine on NR1/NR2A and NR1/NR2B were (4.1 ± 2.5) × 10-6 mol/L and (3.0 ± 0.3 ) × 10-6 mol/Lrespectively. Magnesium and s( + )-ketamine used in combination decreased IC50s more than 90% at both receptors. Isobolographic analysis demonstrated superadditive interactions. Conclusions s( + )-ketarnine and magnesium inhibit responses of recombinantly expressed NMDA recptors non-competitively, and the combinations of the two drugs produces a synergistic effect.

Plateau environment has a wide range of diurnal temperatures and thin air. The surgical shelter needs to resist the huge temperature shock and work in harsh environments, placing higher noise immunity requirements on the microenvironment temperature control system. The traditional microenvironment control of surgical treatment shelters mostly use instrument display and switch control, with a high failure rate and functional dispersion. We have designed a plateau microenvironment temperature control system with PLC as the control center and the touch screen as the Human Machine Interface so that real-time monitoring and control of temperature is achieved and the plateau temperature shock is resisted while the heater fuel ratio can be adjusted properly to adapt to plateau environment. This paper describes the control system hardware, software and algorithm design in detail.

Objective To explore the anti-sliding plating for Hoffa fractures by comparing the me-chanical properties of anti-sliding plates and cancellous bone screws. Methods Twenty cases of the same type of Hoffa fracture in the model femur were randomly divided into 4 even groups. Group A used 2 antegrade cancellous bone screws; Group B used 2 retrograde cancellous bone screws forwards; Group C used anti-sliding plate and locking screw fixation; Group D used anti-sliding plate and cancellous bone screw fixation. All the samples were subjected to the cycle fatigue and the maximum failure load tests. Results The fatigue test revealed no significant difference in the mean maximum displacements at the 10, 100, 1000, 10 000 cycles between the 4 groups. In the maximum failure load test, there were significant differences between Group A [(1224±72) N] and Groups C and D [(2183±227) N and (2124±235) N], as well as between Groups B [(1405±235) N] and Groups C and D; there was no significant difference between Group A and Group B, neither between Group C and Group D, Conclusions In the initial period after secure fixation for Hoffa fractures, anti-sliding plates and cancellous bone screws can all provide satisfactory mechanical stability and strength. But anti-sliding plating is recommended for cases of long healing expected, patients with great body mass index, and patients with poor compliance.
