Introduction:This study aimed to assess the clinical efficacy of Pidan Jianqing decoction in the treatment of type 2 ***:A total of 72 patients with type 2 diabetes differentiated as spleen deficiency with damp-heat syndrome were randomly assigned to a treatment group(n=35)or control group(n=32).Patients in the control group received diet and exercise guidance and medication in the form of 0.5 g metformin hydrochloride tablets,while patients in the treatment group received Pidan Jianqing decoction in addition to the treatment given to the control *** was evaluated after 8 weeks of ***:Efficacy was 91.4%in the treatment group versus 68.8%in the control group,which was a statistically significant difference(P<0.05).Significant group differences were also noted in the number of patients with improvement in symptoms such as dry mouth and polydipsia,frequency of urination and polyuria,abdominal distention and loss of appetite,fatigue and weakness,and sticky stools(all P<0.05),with greater improvement in the treatment group compared to the control *** fasting blood glucose(FBG)and 2 h postprandial blood glucose levels significantly improved in both groups after treatment(P<0.05);however,there was no significant difference in glycated hemoglobin levels before and after treatment in both ***:Pidan Jianqing decoction can lower blood glucose levels and improve symptoms in patients with type 2 diabetes.

An inverted planar heterojunction perovskite solar cell （PSC） is one of the most competitive photovoltaic devices exhibiting a high power conversion efficiency （PCE） and nearly free hysteresis in the voltage-current output. However, the band alignment between the transport materials and the perovskite absorber has not been optimized, resulting in a lower open-circuit voltage （Voc） than that of regular PSCs. To address this issue, we tune the band alignment in perovskite photovoltaic architecture by introducing bilayer structured transport materials, e.g., the hole transport material poly（ethylenedioxythiophene）：poly（styrene sulfonate）（PEDOT：PSS）/V2Os. In this study, solution processed inorganic V2Ox interlayer is incorporated into PEDOT：PSS for achieving improved film surface properties as well as optical and electrical properties. For example, the work function （WF） was changed from 5.1 to 5.4 eV. A remarkably high PCE of 17.5% with nearly free hysteresis and a stabilized efficiency of 17.1% have been achieved. Electronic impedance spectra （EIS） demonstrate a significant increase in the recombination resistance after introducing the interlayer, associated with the high Voc output value of 1.05 V. Transient photocurrent and photovoltage measurements indicate that a comparable charge transport process and an inhibited recombination process occur in the PSC with the introduction of the V20x interlayer.

建立稳健的车体耐撞结构是提高汽车碰撞安全性的有效途径。传统的耐撞性优化设计,由于忽视制造工艺、材料特性和边界条件中存在的不确定因素,导致汽车碰撞安全性能不够稳健。近年来,稳健性设计得到广泛的关注,并在汽车工业中得到应用。将稳健性设计方法应用到汽车碰撞安全性设计中,以某轿车的前纵梁为研究对象,运用双响应面方法对其进行稳健性优化设计。采用拉丁超立方抽样(Latin hypercube sampling,LHS)方法和最小二乘方法创建碰撞响应的二阶多项式双响应面模型,将材料特性作为不确定性因素。稳健性优化后,对前纵梁碰撞性能的稳健性与优化前进行对比分析。分析结果表明,该稳健性设计方法精度较高;经稳健性优化后,前纵梁碰撞性能的稳健性获得了显著提高,且质量减少了3.32%。
