Objective Through visiting the patients with atrial fibrillation who are accepting the anticoagulation therapy of warfarin， and retrospectively analyzing multiple factors which effected warfarin dosing and relationship of dosing and INR，we try to discuss a technique of effective and safe application of warfarin. Methods Retrospective analysis of hospital records were taken from 45 patients with primary diagnosis of AF. Patients enrolled were devided into group A with a starting dose of 1.25 mg/d or 1.5 mg/d， group B 2.5 mg/d or 3 mg/d. Acoording to maintaining dose， group C with a maintaining dose of less than 2 mg/d， group D 2∼3.5 mg/d，and group E exceeding 3.5 mg/d. In the case of dose unchanged， it's considered as reaching the mark when INR stability in 2.0∼3.0. Results the percentage of INR up to the standards， in group A 14.3％，group B 48.2％， group A was higher than the B （ = 0.018） .The values of INR were not statistically significant between group C，D and E. C group detected a total of six times greater than 3.0 （12.0％），D and E respectively 3.0％ and 2.0％， there are different between the value of a statistical significance. Each group's average maintaining dose was different in statistics（C as 0.738±0.152 mg/INR， D as 1.230±0.267 mg/INR，E as 2.056±0.379 mg/INR， ＜0.001）. Conclusion AF patients who choose 2.5 mg/d or 3 mg/d as a starting warfarin dose possess of higher INR standardized rate than chose who received lower dose，and furthermore，it dosen't increase the incidence of overanticoagulation. Patients who hold lower maintaining dose are more tendential of over-anticoagulation （INR＞3.0）. [ABSTRACT FROM AUTHOR]

The dynamic cushioning properties of locking clutch for a hydrodynamic transmission vehicle are studied to improve the locking quality in the transition process from hydrodynamic transmission operating condition to mechanical condition, in particular, to reduce the impact in vehicle’s locking process.The dynamic models for hydrodynamic torque converter with locking function and its input and output components are established. And the effects of oil-filling, buffer boosting, and step boosting on the locking quality during locking are analyzed. The optimal Latin hypercube design method is used to optimize the buffer slope in the buffer boost stage. The quality evaluation parameters, such as jerk, sliding time and sliding work, before and after optimization are compared using the proposed locking quality evaluation function. A locking characteristic test verification bench was built to verify the locking qualities before and after optimization. The results show that the proposed dynamic system simulation model can be used to accurately predict the dynamic locking process. The locking quality after optimization is significantly improved compared with the result before optimization, and the impact is significantly reduced. [ABSTRACT FROM AUTHOR]

BACKGROUND: Cervical pedicle screw fixation is a reliable method for the treatment of traumatic and non-traumatic cervical instability and cervical disc removal and fixation; however, the operation risks and the failure rate of screw insertion are still high. At present, the digital navigation template with digital computer technology, used in the department of orthopedics, has the advantages of accurate screw insertion and a small error in the screw insertion depth. OBJECTIVE: To observe the clinical efficacy and safety of the digital navigation template combined with cervical pedicle screw implantation. METHODS: This is a prospective, single-center, self-controlled, clinical trial. Thirty-two patients with cervical spondylosis will be recruited from the Harrison International Peace Hospital, Hebei Province, China. Before surgery, a three-dimensional (3D) navigation model of the cervical vertebrae will be designed by 3D reconstruction. The navigation template will be generated by 3D printing. The cervical pedicle screws will be implanted according to preoperatively designed models and the screw positions will be observed by computerized tomography (CT) after surgery. The patients will be followed up for 40 months. The primary outcome measure is the excellent and good rate of screw position 40 months after implantation. The secondary outcome measures include the Visual Analog Scale score, American Spinal Injury Association classification, cervical X-ray and CT images before implantation and 40 months after implantation, and the incidence of adverse reactions 40 months after implantation. The protocols have been approved by the Ethics Committee of the Harrison International Peace Hospital in China (approval number: 20120630). The study protocol has been conducted in accordance with the Declaration of Helsinki, formulated by the World Medical Association. Written informed consent will be obtained from all participants. The recruitment of subjects will begin in December 2017. Samples and data will be collected from December 2017 to April 2019. Outcome measures will be analyzed in October 2020. This trial will be completed in November 2020. The results of the trial will be reported in a scientific conference or disseminated in a peer-reviewed journal. This trial has been registered in the Chinese Clinical Trial Registry (registration number: ChiCTR-ONC-17013481). DISCUSSION: We will verify a high success rate of cervical pedicle screw implantation using the digital navigation template. The operation is simple and quick, with good efficacy and safety.

Aiming at tlie problem that tlie energy recovery effect of hybrid pneumatic engine based on single stage energy storage system decreased witli the increase of tlie pressure of tlie air tank，double stage energy storage system was used into hybrid pneumatic engine，the view-point that the COP (coefficient of performance) could be improved by changing the inlet pressure was drawn preliminary. Based on the theory of variable mass thermodynamics，a mathematical model of compressed air circulation which was verified by testbed was established. Through the steady state simulation of the model，the influence of inlet pressure and air tank pressure on compressing braking process were obtained. The results indicate that the change of inlet pressure and the air tank pressure afect the quality of the recycled compressed air per circulation linearly. the ratio of air tank pressure and inlet pressure is a key factor affecting the COP which will decrease when the ratio increases.

In order to improve the braking efficiency of dual torus hydrodynamic retarder, the parameter optimization design of blade top arcs is studied. A numerical model of internal flow passage is established based on the parametric modeling method of blade top arcs. The computational fluid dynamics method is used for design of experiments with the radius and distance of blade top arcs as design variables, and the sensitivity analysis of two parameters having the effect on brake performance is made. A gradient optimization algorithm is used to get the optimum result by building an approximate model of braking torque. The influence of design parameters on internal flow field and external brake performance is analyzed, and the simulated results are compared with the experimental data. The results show that the brake performance of hydrodynamic retarder after optimization is significantly improved, the braking torque is increased by 70.8%, and the blade structure meets the strength requirement.

Unstable surface states of the sliding interface lead to fluctuant emissivity, causing inaccurate infrared temperature measurement. In this study, wideband emissivity on end-face sliding contact interface, which was composed of a 45# steel upper sample and a tin bronze lower sample, was researched under grease lubrication by an infrared temperature measurement system, which was designed and built using a thermal imager and 3 infrared thermometers. Lithium base grease contains molybdenum disulfide of 10% (mass fraction). Three through-holes were drilled on the lower sample, right below the contact area. Through these holes, the infrared thermometers aimed at the contact area, and the brightness temperature of the contact area (BTCA) could be obtained with the constant emissivity of 1. All the lateral surfaces of the samples and the fixture were sprayed with matt black paint, which had a constant emissivity of 0.95. Then the temperature distribution of the lateral surface was obtained using the thermal imager which was placed 400 mm away from the samples. The temperature of the point P (TP), which was located in the outermost of the contact area and whose temperature was measured by the thermal imager, was considered as the actual real average temperature of the contact area. A series of experiments were carried out with different load and rotational speed, and the instantaneous data, such as friction coefficient were recorded. And the wideband emissivity was calculated with the TP and BTCA. Through the comparison and analysis, it was found that the distribution of the lateral surface of lower sample tended to be homogeneous after 1 800 s friction. However, on the upper sample’s lateral surface, the nearer from the contact area, the higher the temperature. The TP and BTCA showed a similar variation trend during the friction process, which steeply rose in the beginning and then slowed down. With the rotation speed of 400 r/min, the temperature rise under 100 N was higher than that under 200 N, because the temperature rise was not just affected by the load and sliding speed, but also by the friction coefficient. The BTCA was obviously less than the TP, because the preset emissivity for the thermometers exceeded the real wideband emissivity of the interface. The wideband emissivity of the interface was 0.8 because the grease film and the surface states changed. According to the changing curve of friction coefficient and wideband emissivity, the friction process was divided into running-in stage and steady wear stage. In the running-in stage, the wideband emissivity slumped from 0.96 to 0.86 (slightly different under different test conditions) due to the radical changes of surface states caused by the radical surface morphology and temperature changes. In the steady wear stage, in contrast to the previous, the wideband emissivity grew slowly and trended to be stable. This experimental result reveals the wideband emissivity change regularity on the sliding contact interface under grease lubrication during the friction, and the study may also provide a reference for improving the precision of infrared temperature measurement.
