In practice of forensic medicine, potential disease can be associated with fatal asphyxia in re-straint position. Research has demonstrated that nitric oxide (NO) and nitric oxide synthase (NOS) are plentifully distributed in skeletal muscle, contributing to the regulation of contractile and relaxation. In the current study, respiratory functions, indices of diaphragmatic biomechanical functions ex vivo, as well as NO levels in serum, the expressions of diaphragmatic inducible NOS (iNOS) mRNA, and the effects of L-NNA on contractility of the diaphragm were observed in sepsis induced by cecal ligation and punc-ture (CLP) under the condition of restraint position. The results showed that in the CLP12-18 h rats, respiratory dysfunctions; indices of diaphragmatic biomechanical functions (Pt, +dT/dtmax, -dT/dtmax, CT, Po, force over the full range of the force-frequency relationship and fatigue resistance ) declined progressive-ly; the NO level in serum, and iNOS mRNA expression in the diaphragm increased progressively; force increased significantly at all stimulation frequencies after L-NNA pre-incubation. Restraint position 1 h in CLP12 h rats resulted in severe respiratory dysfunctions after relative stable respiratory functions, almost all the indices of diaphragmatic biomechanical functions declined further, whereas little change took place in NO level in serum and diaphragmatic iNOS mRNA expression; and the effects of L-NNA were lack of statistical significance compared with those of CLP12 h, but differed from CLP18 h group. These results suggest that restraint position and sepsis act together in a synergistic manner to aggravate the great reduction of diaphragmatic contractility via, at least in part, the negative modulation of NO, which may contribute to the pathogenesis of positional asphyxia.

4.Research progress of anterior cervical interbody fusion system Zero-P in patients with cervical spondylosis
China Modern Doctor 2018;56(14):159-163
ACDF is a classical operation for the treatment of cervical spondylosis. Applying anterior cervical titanium plate during operation is with significant advantages. However, researches including long-term follow-up found there were many complications of the application of anterior cervical titanium plate, especially in the long-segment ACDF. To solve the problems of anterior cervical titanium plate application, a new kind of zero-profile anterior cervical inter-body fusion system appeared. Since Zero -P anterior cervical interbody fusion system began to be applied in clinical treatment, there were many studies on single/double -segment ACDF. The safety and effectiveness of this system has been confirmed by massive researches. The method of operation on the cervical spondylosis of 3/4 segment is still controversial. It has been a hot issue to treat cervical spondylosis of 3/4 segment using ACDF with the application of Zero-P. However, the safety and effectiveness of clinical application of this method have not reached a consensus and remain controversial.

Objective To investigate the effect of video-based teaching in the training of nursing operation for newly-contracted nurses. Methods One hundred and twenty one nurses newly recruited in September 2011 to September 2012 were set as the control group, another 128 in October 2012 to October 2013 were set as the experiment group. The former were trained and assessed with traditional training method and the latter were trained for 1 year in video-based teaching methodology. After training, both groups were examined about their operation skills and meanwhile a survey on video-based teaching was conducted. Result After training, the results in operating skills evaluation in the experiment group were significantly better those of the control group (Z=2.82, P<0.05). Conclusion Compared with traditional training method, the video-based teaching can raise the level of nursing operation skills and significantly improve the quality of nursing, thus worthy of popularization and application.

Objective To investigate the relationship between diffusion time and diffusion tensor-derived parameters. Method Diffusion tensor data sets were obtained from 11 healthy volunteers using 8 different levels of diffusion time while keeping the diffusion sensitive gradient magnetic field strength fixed. Diffusion tensor-derived parameters with variant diffusion time for six regions of interest were calculated and compared. Result There was statistically significant difference in mean diffusivity (MD) of variant diffusion time (P0.05). Conclusion There is no diffusion time dependent in FA, but MD are diffusion time dependent. The reason may be attributed to the difference of the diffusion properties between the intra- and extra-cellular water molecules.

Objective:To evaluate the efficacy and safety of low molecular weight heparin and unfarction heparin in patients with coronary heart disease during percutaneous coronary intervention by investigating the MACE beteewn the percutaneous coronary intervention procedure and post percutaneous coronary intervention 72 hours.Methods:200 patients with coronary heart disease who accepted percutaneous coronary intervention were investigated in this study.According to the anticoagulants,these patients were divided into LMWH subgroup(117 cases) and UFH subgroup(83 cases).According to conventional method,the MACE what happened during percutaneous coronary intervention procedure and post percutaneous coronary intervention 72 hours come from each group of patients was investigated and these statistics were analysised so that evaluate the efficacy and safety of low molecular weight heparin and unfarction heparin.Results:(1) There were no statistical significance in baseline characteristics between the each group (P>0.05).(2) There were statistical significance in the incidence of TIMI flow slows between the each group (P<0.05),low molecular weight heparin is superior to unfarction heparin in terms of efficacy.(3)There were no statistical significance in death between the each group (P>0.05),but there were statistical significance in bleeding / hematoma complications,and other (pericardial tamponade,chest pain,cardiogenic shock,cardiac rapture,ventricular septal perforation,ventricular tachycardia,ventricular fibrillation,cardiac arrest,Aspen attack,stent thrombosis and so on) between the each group (P<0.05),low molecular weight heparin less adverse reactions,higher safety.Conclusion:Low molecular weight heparin in the percutaneous coronary intervention effect is more significant,and less than UFH adverse reactions and high safety,more suitable for percutaneous coronary intervention anticoagulant therapy.
