AIM: To investigate the effect of a new type of rhinodacryocystostomy combined with fluticasone propionate on patients with chronic dacryocystitis.METHODS: A total of 100 patients(100 eyes)with chronic dacryocystitis who admitted to our hospital between January 2021 and December 2022 were enrolled in the prospective study. The patients in the study were divided into a control group(n=50)and an observation group(n=50)based on their admission order and number. Patients in the control group were treated with novel rhinodacryocystostomy, while patients in the observation group were treated with a new type of rhinodacryocystostomy combined with fluticasone propionate. The preoperative and postoperative best corrected visual acuity(BCVA), quality of life score, and recurrence of chronic dacryocystitis were compared between the two groups of patients.RESULTS: All patients completed the postoperative 6 mo follow-up, and the total effective rate of patients in the observation group was better than that of patients in the control group(98% vs 84%, P=0.001). There was no significant difference in preoperative and postoperative BCVA between the two groups(P>0.05). Preoperatively, there was no significant difference in the quality of life scores between the two groups of patients(P>0.05); At 6 mo postoperatively, the quality of life scores of patients in the control group, including physical function, psychological function, social function, and material life status, were lower than those in the observation group(all P

Lane width is crucial for traffic safety management. Previous studies have shown that inappropriate width will lead to an increase in accident probability and unsafe driving behaviors. However, there have been limited studies on determination method of special lane width for different models, especially for passenger cars. To tackle this problem, the lateral driving behavior characteristics of the expressway need to be clarified. This work aims to obtain the appropriate lane width according to the vehicles' width and lateral position characteristics. In this study, the lane lateral residual width (the distance between the vehicle body's contour and the lane marking on the same side) and the lateral safety margin are extracted as characterization indices of vehicle lateral characteristics from natural driving trajectory data of expressways. The effect of vehicle type, driving speed, and lane position on the expressway's trajectory behavior is investigated. The results show that the utilization rate of lane width is higher in the outer lane compared to the inner lane. As driving speed increases, vehicles in the inner and middle lanes exhibit shy away effect, moving away from obstacles. Substantial variations exist in the lateral width of lanes among different vehicle types. When driving in the same lane, passenger cars' lane lateral residual width that is 0.4–0.5 m wider than that of heavy vehicles. The recommended lane width for the safe operation of trucks on expressways is 3.75 m. After a comprehensive analysis of vehicle width, trajectory oscillation, and lateral safety margin, this study proposes a minimum lane width of 3.25 m and a recommended general width of 3.5 m for a passenger car‐only expressway. This study holds great significance in enhancing road safety and provides a valuable theoretical foundation for the design of lane width in a passenger car‐only expressway. [ABSTRACT FROM AUTHOR]

The multiple enhancement of electromagnetic interference (EMI) shielding performance through facile operation is attractive for the future development of EMI shielding materials. Herein, composites of carbonized wood and nickel (CW/Ni) with different orientation angles are obtained by impregnation and carbonization. Benefiting from the through-pore structure, the shielding effectiveness (SE) of CW rises from 29.3 to 57.5 dB in the X-band as the orientation angle shifts from 90 to 0°. Moreover, the orientation angle of the natural wood has an influence on the impregnation results. CW/Ni-0° has the highest nickel content in the same impregnation condition, and the SE value of CW/Ni-0° is further improved to 76.4 dB in the X-band owing to an increase in internal reflection, graphitization, and magnetic loss. CW/Ni-0° achieves high SSE and SSE/t via modulation of orientation angles. This work provides an effective approach to enhance the performance of shielding materials. [ABSTRACT FROM AUTHOR]
