[Objective] The refractory lignin is an important factor restricting the utilization of agricultural and forestry wastes resources with high lignocellulosic content. Screening lignin-degrading strain can provide reference for efficient utilization of agricultural and forestry wastes. [ Method] In the study, strain was isolated from extensive collection of plant litter materials by using guaiacol chromogenic method and aniline blue fading method. The enzyme activities of three lignin-degrading enzymes ( laccase, manganese peroxidase and lignin peroxidase) were measured. To further verify the degradation ability of the strain, vineyard prunings (common agricultural and forestry wastes) were selected as materials to analyze the degradation of cellulose, hemicellulose and lignin in liquid fermentation of vineyard prunings. [ Result] A strain HUA with lignin decomposition characteristic was screened from plant litter. The strain HUA showed obvious reddish-brown color circle on guaiacol-PDA plate, and finally produced decolorizing reaction on aniline blue-PD A plate. Based on morphology and molecular biological methods, it was identified as Peniophora crassitunicata. Three lignin-degrading enzymes (laccase, manganese peroxidase and lignin peroxidase) in fermentation broth of this strain were 53. 18, 174. 01, 9. 51 U/L, respectively. The results of vineyard prunings liquid fermentation showed that the strain could degrade lignocellulosic components effectively. After 20 days of fermentation, the degradation rates of cellulose, hemicellulose and lignin reached 17. 50%, 36. 55%, 10. 33%, respectively. [Conclusion] The strain HUA obtained in this study promotes the degradation of lignocellulose components in vineyard prunings, which provides high-quality strain resources for the efficient degradation of lignocellulose and accumulated relevant data for subsequent application studies of strain.

In order to solve the problem that the warning threshold fixation of time-to-collision (TTC) algorithm causes prematurely warning at low speed and warning with a delay at high speed, this paper presents a safety time warning method of anti-collision based on vehicle driving speed. Firstly, vehicles can get the driving status information of themselves and others timely by on-board equipment. On-board equipment can get the information about latitude, longitude, speed and heading angle of the vehicle in real time. Then, according to the driving status information, vehicle coordinates information can be obtained by Gauss plane rectangular coordinate system established. After that, the possible collisions can be classified and processed. In reality, all vehicles are not required to carry out vehicle collision warning, so it can reduce vehicle collision processing and optimize the performance of the algorithm by classifying the possible collisions of vehicles, and it also can facilitate the use of different collision warning algorithms for different types. Mathematical model can be used to classify the possible collisions. Collision is divided into linear collision and side impact, and linear collision includes frontal and rear collision. For linear collision, the precondition of collision is that the lateral distance of the 2 vehicles is less than the width of vehicle. For the side impact, vehicles maintain current speed and direction, and according to the current state of vehicles, it can predict future vehicle running track, determine vehicle collision point and calculate vehicle collision time difference, and the collision time difference is used to determine the initial conditions of side impact. Next, the initial condition of vehicle collision is met, vehicle anti-collision safety time can be set based on vehicle driving speed, and then it will be compared with the time required for vehicle collision occurring for each vehicle. If the risk of collision exists, the application equipment displays warnings to remind drivers. The safety anti-collision time is the shortest time for drivers to take measures to avoid the danger. Response time of the driver is the time when the alarm signal is received, and response time of the braking system includes the reaction time of the braking system, the braking coordination time and the continuous braking time. Based on this, it is possible to get early warning of collision risk from the driver’s reaction to braking reaction. Through the different vehicle speed, it can determine the different safety collision time, and through detecting vehicle speed changes, it can timely change vehicle anti-collision safety time threshold. Entire system can receive the vehicle status information through the on-board equipment in real time and continuously. When the precondition of linear collision and side collision is satisfied, the time needed for vehicle collision is calculated in real time, and then compared with the time threshold of safety warning. If there is a risk of collision, it will warn on the application device. Finally, experiments are carried out to verify the performance of the proposed method. In the simulation experiment, compared with the general TTC fixed threshold method, this method reduces the false alarm rate by up to 9.04%, and decreases the missing alarm rate by 8.3%. In real vehicle test, experimental results show that the suitable early warning rate of this proposed method is 88.89%, and premature warning rate of general TTC fixed threshold method reached 81.48%, and late warning rate reached 70.37%. It can be concluded that the proposed method in this paper is more effective for vehicle hazard warning, more in line with the actual situation of the vehicle anti-collision, and improves the safety of vehicle driving.

OBJECTIVE: To explore the efficacy of salvianolic acid combined with creatine phosphate sodium in treatment of angina pectoris of coronary heart disease. METHODS: 174 patients with angina pectoris of coronary heart disease admitted into the Third People’s Hospital of Shenzhen Longgang District from Jan. 2017 to Feb. 2018 were extracted to be divided into observation group and control group via the random number table, with 87 cases in each. The control group was given salvianolic acid, while the observation group additionally received creatine phosphate sodiumbased on the control group. After continuous treatment of 15 d, the clinical efficacy, echocardiographic parameters and adverse drug reactions of two groups were compared. RESULTS: The total effective rate of observation group was 94.19%(81/86), significantly higher than that of control group(83.72%,72/86), with statistically significant difference(P<0.05). After treatment, the echocardiographic indexes of the observation group were significantly better than those of before treatment and the control group after treatment(P<0.05). The incidences of adverse drug reactions in observation group and control group were respectively 5.81%(5/86) and 8.14%(7/86), without any statistical significance(P> 0.05). CONCLUSIONS: The efficacy of salvianolic acid combined with creatine phosphate sodium in treatment of angina pectoris of coronary heart disease is significant, which can help to improve the cardiac function of patients with fewer adverse drug reactions.
