针对网联自动驾驶车辆(connected autonomous vehicle,CAV)渗透路网,对不同断面特性造成的机非交互情境差异性干扰交通流的情况进行秩序评价。以南浔泰安西路为例,引入CAV渗透比例,统计分析路段高峰期的交通流数据,提出了遗传算法校正CAV跟驰模型仿真参数,搭建VISSIM仿真平台,以效率和安全两个角度为指标进行秩序评价。结果表明,路幅板块增多和渗透率的升高利于城市道路路网的运行,机非物理隔离可有效保证路面车辆行驶的安全性。

目的探讨血清高尔基体跨膜糖蛋白73(GP73)、壳多糖酶3样蛋白1(CHI3L1)水平变化与慢性乙型肝炎(CHB)患者肝纤维化及病变程度的关系。方法采用病例对照研究,选取长沙市第一医院感染科2020年6月至2023年6月确诊的80例CHB感染且发生肝纤维化患者作为肝纤维化组,感染科门诊既往确诊的CHB感染但未发生肝纤维的患者120例作为对照组,对比两组患者的血清GP3、CHI3L1、肝功能、纤维化指标,并根据Scheuer系统标准将肝纤维化组患者分为轻度、显著肝纤维化患者进行分层分析。结果肝纤维化组患者血清GP3、CHI3L1水平显著高于对照组,差异有统计学意义(P<0.05);以血清GP3、CHI3L1、GP3+CHI3L1分别绘制ROC曲线,其诊断CHB患者发生肝纤维化的灵敏度为:62.81%、60.94%、96.33%,特异度为:80.66%、80.05%、75.30%,曲线下面积AUC值分别为:0.792、0.756、0.908;肝纤维化组患者的ALT、AST、HA、LN、PCⅢNP、CⅣ、CG水平均高于对照组,PLT测定值低于对照组,差异有统计学意义(P<0.05);中重度肝纤维化患者49例(S2期33例、S3期16例)、轻度肝纤维化患者31例(均为S1期),中重度肝纤维化患者血清GP3、CHI3L1水平显著高于轻度患者,差异有统计学意义(P<0.05);中重度肝纤维化患者的DBIL、ALT、AST、HA、LN、PCⅢNP、CⅣ、CG水平均高于轻度组,PLT测定值低于轻度组,差异有统计学意义(P<0.05)。结论CHB肝纤维化患者的血清GP3、CHI3L1水平显著升高,并且与肝纤维化程度有一定的相关性,两项指标结合应用有利于诊断CHB患者发生肝纤维化。

A series of novel furan/thiophene and piperazine-containing 1,2,4-triazole Mannich bases and bis（1,2,4-triazole） Mannich bases have been conveniently synthesized via Mannich reaction with triazole Schiff bases, various pipera- zinc derivatives, and formaldehyde as intermediates in good yields. Their structures were characterized by melting points, ~H NMR, 13C NMR, IR and elemental analysis. The preliminary bioassay showed that most compounds ex- hibited significant in vitro and in vivo fungicidal activity against several test plant fungi. Among 32 new compounds, the trifluoromethyl-containing compounds showed superior activity than the methyl-containing ones. Several com- pounds, such as FS, F9, F10, G5, HT, 118, 13 and 14, were comparable with some commercial fungicides against different fungi during the present study and could be further structurally optimized. Meanwhile, several compounds showed good herbicidal activity against Brassica campestris at 100 ~tg/mL and KARl inhibitory activity at 200 μg/mL. However, compounds exhibited poor insecticidal activity against oriental armyworm at 200 μg/mL in the preliminary studies. The research results will provide useful information for the design and discovery of new agro- chemicals with novel heterocyclic structures.
