Engineering shallow,large-span rock tunnels challenges deformation control and escalates construction *** study investigates the excavation compensation method(ECM)and its associated technologies to address these *** five key technologies,the ECM effectively modulates radial stress post-excavation,redistributes stress in the surrounding rock,and eliminates tensile stress at the excavation ***-tensioning measures further enhance the rock’s residual strength,establishing a new stability *** tests corroborate the method’s effectiveness,demonstrating a crown settlement reduction of 3–8 mm,a nearly 50%decrease compared to conventional construction ***,material consumption and construction duration were reduced by approximately 30%–35%and 1.75 months per 100 m,***,the ECM represents a significant innovation in enhancing the stability and construction efficiency of large-span rock tunnels,marking a novel contribution to the engineering field.

目的:探讨补肾温阳化瘀方治疗内异症的可能作用机制。方法:选用SPF级雌性大鼠复制腹膜型内异症大鼠模型,将造模成功的大鼠分为4组:补肾温阳化瘀方高剂量组(16只)、低剂量组(16只)、丹那唑组(16只)、模型组(17只),并设对照组(12只)。运用免疫组化(S-P)法,检测内异症模型大鼠治疗前、后异位内膜组织中缺氧诱导因子-1α(HIF-1α)、葡萄糖转运因子-1(GLUT-1)的表达,并比较治疗前后异位灶体积变化。结果:补肾温阳化瘀方高、低剂量组及丹那唑组治疗后子宫内膜异位灶体积较治疗前明显缩小(P<0.05),且以补肾温阳化瘀方高剂量组最显著(P<0.01);HIF-1α,GLUT-1在模型组异位内膜的表达与对照组在位内膜相比显著升高(P<0.01);补肾温阳化瘀方高、低剂量组及丹那唑组均能够显著抑制HIF-1α,GLUT-1的高表达(P<0.01),与对照组表达无明显差异,且以中药高剂量组作用效果最显著,低剂量组次之;丹那唑组与补肾温阳化瘀方高剂量组比较抑制效果有差异(P<0.05)。结论:补肾温阳化瘀方可能通过抑制HIF-1α与GLUT-1的表达达到治疗内异症的目的。

目的：观察祛瘀汤对药物流产患者绒毛及血清中表皮生长因子(EGF)的影响,探讨祛瘀汤降低药流后不全流产的可能机制。方法：将自愿要求药物流产且符合纳入标准的早孕妇女41例随机分为3组。对照1组13例,单纯采用药物流产治疗；对照2组17例,在对照1组治疗基础上加服益母草冲剂治疗；治疗组11例,在对照1组治疗基础上加服祛瘀汤(由桃仁、益母草、丹参、莪术、川芎、大黄、黄芪、柴胡、地鳖虫、怀牛膝等组成)治疗。主要观察3组绒毛、血清EGF的含量。结果：治疗后,对照1组、对照2组、治疗组绒毛EGF含量分别为1．5021μg/L、0．9963μg/L、0．6897μg/L,血清EGF含量分别为1．5836μg/L、1．0959μg/L、0．7267μg/L,经单因素方差分析,3组中各组间总体均数不全相等。经Newman Kenk q检验证实,3组间两两比较,差异有非常显著性意义(P＜0．01),3组间EGF含量由低到高依次为治疗组＜对照2组＜对照1组。结论：祛瘀汤与米非司酮具有协同作用,使血清中EGF含量下降,进而作用于绒毛,使其难以维持正常的早孕状态。

目的观察补肾温阳化瘀方对子宫内膜异位症(endometriosis,EM)肾阳虚血瘀证模型大鼠缺氧诱导因子-1α(hypoxia inducible factor-1,HIF-1α)、脯氨酸羟化酶2(proline hydroxylase2,PHD2)、希佩尔-林道抑癌基因(von Hippel Lindau disease,VHL)表达的影响,探讨EM发病机制及补肾温阳化瘀方治疗EM的作用机制。方法将50只SD大鼠随机分为正常组、假手术组、模型组、中药组、西药组,每组10只。其中正常组、假手术组常规饲养,模型组、中药组、西药组采用"延长冰箱冷冻加冰水浸泡"30天,再结合"自体移植法"创建EM肾阳虚血瘀证模型。术后中药组给予补肾温阳化瘀方(3.33 g/mL)1mL灌胃,西药组予以孕三烯酮0.5 mg/(kg·d)灌胃,模型组、正常组、假手术组灌服等体积的生理盐水,共给药4周。观察大鼠异位灶大小及形态,放免法检测血清CA125、血浆环磷酸腺苷(cAMP)、血浆环磷酸鸟苷(cGMP)的表达,HE染色光镜观察子宫在位内膜及异位组织形态学的变化,免疫组化SABC法、Western blot法检测HIF-1α、PHD2、VHL蛋白表达及含量,RT-PCR方法检测HIF-1α、PHD2、VHL mRNA表达。结果模型组大鼠异位灶生长明显,中药组、西药组治疗后,异位灶体积明显缩小。与正常组及假手术组比较,模型组CA125及cGMP水平明显升高,cAMP水平明显降低(P<0.05);HIF-1αmRNA、蛋白表达及含量均升高(P<0.05),PHD2、VHL mRNA、蛋白表达及含量均降低(P<0.05)。与模型组比较,中药组及西药组CA125及cGMP水平明显降低,cAMP水平明显升高,HIF-1αmRNA、蛋白表达及含量均降低,PHD2、VHL mRNA、蛋白表达及含量均升高,差异均有统计学意义(P<0.05)。与中药组比较,西药组PHD2蛋白含量更高(P<0.05)。HIF-1α与PHD2呈负相关(r=-0.799,P=0.00),HIF-1α与VHL呈负相关(r=-0.625,P=0.003)。结论补肾温阳化瘀方可有效治疗EM,其作用机制可能与降低HIF-1α、CA125、cGMP含量,上调PHD2、VHL、cAMP表达有关。

Cobalamin(Cbl)-dependent radical S-adenosyl-L-methionine(SAM) proteins constitute the largest collection of the radical SAM superfamily that has hundreds of thousands of individual members. Many of these proteins are involved in the biosynthesis of pharmaceutically important natural products to catalyze chemically demanding reactions. In the biosynthetic pathway of chuangxinmycin(CXM), a unique indole alkaloid antibiotic with potent anti-infective activity, functionalization of the characteristic thiopyrano[4,3,2-cd]indole scaffold by regio-and stereoselective C3-methylation is believed to rely on a Cbl-dependent radical process, which, however, remained to be reconstituted biochemically. We here report the dissection of this enzymatic process, which requires the incorporation of Cxm8, a Cbl-dependent radical SAM protein, with Cxm9, a DUF5825family protein that shares no homology to any proteins of known functions. Cxm8 and Cxm9 function together by forming an unexpected heterodimeric complex that selectively catalyzes C3-methylation of the tricyclic indole-S-hetero ring system in a successive manner, achieving CXM and a recently identified, C3-dimethylated congener. Detailed biochemical characterization,isotope labeling, structural simulation and bioinformatics analysis rationalized the catalysis of the Cxm8/Cxm9 complex and particularly the necessity of the DUF5825 protein for C3-methylase activity. This is the first example that a Cbl-dependent protein acts with a partner to exhibit radical SAM activity.
