Intercropping of crops that can secrete bacteriostatic active substances can not only inhibit the occurrence of disease but also have an important effect on plant ***,the effects of dandelion intercropping on pepper blight control and pepper growth remain *** this study,the control effect of dandelion on pepper blight was studied by inoculating the pepper leaves with Phytophthora infestans,and it also discusses the correlation of the occurrence of pepper epidemic disease with the pepper canopy environment,soil environment,pepper photo-synthesis,and yield *** results showed that best plant distance for dandelion intercropping was 20 cm(P20),and the control effect reached 43.31%.As compared to the CK,SOD enzyme,POD enzyme,and PAL enzyme were signiﬁcantly up-regulated during the growth of pepper;chlorophyll content in pepper leaves was signiﬁcantly increased;photosynthetic characteristics were signiﬁcantly increased;stem diameter and yield of crop pepper were effectively improved;and the quality of the pepper product was better,but intercropping dandelion resulted in a signiﬁcant decrease of nutrients in the soil environment of pepper,so a reasonable intercropping distance was *** correlation analysis shows that the incidence of pepper blight(A)was signiﬁcantly positively correlated with soil temperature(Q),intercellular carbon dioxide(L),and canopy air temperature(O).The incidence of capsicum blight(A)was signiﬁcantly negatively correlated with chlorophyll content(F),net photo-synthetic rate(K),stomatal conductance(M),ww rate(N),soil sucrase activity(W),vitamin C(AB),and leaf PAL enzyme(J).Finally,it was deduced that intercropping dandelion could effectively control the occurrence of pepper blight while also demonstrating a complex interaction with the pepper growing environment.

目的:探讨高分辨CT(HRCT)不同征象及其联合应用在表现为磨玻璃结节(GGNs)的同时性多原发肺癌(SMPLC)中的诊断价值。方法:收集我院行HRCT检查、影像表现为GGNs且可疑SMPLC患者资料共114例261枚结节,对每枚结节的HRCT征象和部位进行分析,并与病理进行对照,计算结节的HRCT征象及联合应用诊断肺癌结节的灵敏度、特异度、阴性预测值、阳性预测值、准确度,并与炎性结节的HRCT征象进行比较。结果:114例中确诊SMPLC 94例(肺癌结节208枚,炎性结节51枚,转移瘤2枚);肺癌结节的单一HRCT征象中,边缘清晰完整征的阳性预测值、准确度、阴性预测值最高(分别为93.3%、89.6%、74.0%),胸膜凹陷征、毛刺征的特异度最高(均为98.4%),胸膜凹陷征阳性预测值最高(96.8%);2个征象联合中,血管造影征+边缘完整清晰征的阳性预测值、特异度、准确度均最高(分别为97.3%、90.2%、86.1%),3个及以上征象联合中血管造影征+边缘完整清晰征+其他任何一项的阳性预测值、特异度均最高(分别为98.6%、96.1%);且与51枚炎性结节单一征象或多征象联合具有统计学差异(P<0.05);SMPLC女性发病率明显高于男性,且50~59年龄段女性为发病高峰期。结论:HRCT表现为GGNs,其中2枚及以上结节均具有原发肺癌的征象是诊断SMPLC的基础;结节的血管造影征、边缘完整清晰征单一征象应用在原发肺癌结节诊断中具有较高的灵敏度,但仍具有误诊风险;血管造影征+边缘完整清晰征或+其他征象(空泡征、分叶征、胸膜凹陷征、毛刺征)中的任何一项或多项可提高肺癌结节诊断的特异度,减少误诊的发生;50~59岁女性为高危人群,对其应提高警惕及加强筛查。

This experiment used pumpkin Longyuanlixiang as material to research the effect of different pruning ways with one branch, two branches, and three branches on the sugar-decreasing matters during the ripeness of pumpkin （Cucurbita moschata） fruits. The results showed that pectin contents of pumpkin fruits during the ripeness all increased at first and then dropped in every treatment. The pectin contents under the treatments of one branch and two branches reached the high apex after pollinated for 30 d as well as for 35 d under the treatment of three branches. Pentose and chromium contents of fruits had the same trend under different pruning ways and increased during the ripenes. Three kinds of sugar-decreasing matters contents under treatment of two branches were bigger than treatment of one branch, while treatment of three branches was the lowest.

目的探讨通络养阴方对糖尿病心肌病(diabetic cardiomyopathy,DCM)患者炎症反应及心室重构的影响。方法选取2017年8月—2020年8月本院糖尿病科收治的82例DCM患者,按照随机数字表法分为2组,每组41例。对照组予以常规治疗,观察组在对照组基础上予以通络养阴方治疗。比较2组患者临床疗效、炎症反应水平及心室重构情况。结果治疗后,观察组患者临床治疗总有效率显著高于对照组(P<0.05)。观察组患者外周血中性粒细胞/淋巴细胞(neutrophil to lymphocyte ratio,NLR)、血小板/淋巴细胞(platelet to lymphocyte ratio,PLR)、单核细胞/高密度脂蛋白胆固醇(monocyte to high-density lipoprotein cholesterol ration,MHR)水平明显低于对照组(P<0.05)。观察组患者左室射血分数(left ventricular ejection fraction,LVEF)显著高于对照组,左室舒张末期内径(left ventricular end diastolic diameter,LVEDD)、左室收缩末期内径(left ventricular end systolic diameter,LVESD)显著小于对照组(P<0.05)。结论通络养阴方可通过下调DCM患者血清炎症反应水平、抑制心室重构、改善心功能,进而提高临床疗效。
