导致血不利的原因一是不足,即由于气、血、津、液等物质的缺乏致无源行血;一是不通,即水、湿、痰、饮、瘀、食积、火郁、内风、外伤等病理因素阻滞,致血行不畅。血瘀经脉之内,则水亦瘀积脉中,致脉络胀满,形成水肿。乳腺癌术后患者,金刃本已损伤血脉,术后的放疗、化疗又属祛邪之法,故机体元气受损,气虚无力行血,血运行不畅,导致患侧上肢水肿。故治疗乳腺癌相关淋巴水肿时,应当血水同治,即活血利水之法要贯穿始终。先病血而后病水者,可以活血化瘀为主,利水为辅;先病水后病血者,则以利水消肿为主,酌加活血养血之品。但需要注意的是:①临证时切不可拘泥于单纯的活血利水法,而忽视乳腺癌相关淋巴水肿(breast cancer related lymphedema,BCRL)患者机体本身的状况。②临证勿忽视五脏与血、水的关系,以及肺、脾、肾、三焦与水肿的内在关系。③可多种方法联合运用,审证求因,标本同治。BCRL术后宜补气活血,通脉利水;术后兼化疗者可疏肝健脾、利水消肿;早期可在活血利水基础上,侧重利湿消肿,后期多湿聚为痰,治疗侧重化痰软坚。 相似文献
2‐deoxy D‐glucose (2DG) was tested for efficacy in treating alopecia areata using the C3H/HeJ skin graft model. 2DG has proven to be efficacious in treatment of various mouse models of autoimmunity with minimal serious side effects noted. This agent has been shown to normalize abnormally activated T‐cell populations while also preventing cell surface expression of NKG2D; key factors defining alopecia areata disease progression. Daily oral ingestion of 2DG via drinking water to mice with patchy or diffuse alopecia areata for 16 weeks failed to prevent expansion of alopecia or cause regrowth of hair in treated mice. Histologically, there were no differences between treated and control groups. These results indicate that, while 2DG is effective for some autoimmune diseases, it was not efficacious for the cell‐mediated autoimmune mouse disease, alopecia areata. 相似文献
Background: High-quality adverse drug reaction (ADR) reports are essential for conducting drug safety monitoring in pharmacovigilance. The study aim was to assess the current quality of ADR reports in western China, and to identify problems with ADR report quality.
Research design and methods: A sample of 1139 reports received by the Shaanxi ADR Monitoring Center from January 2015 to December 2017 was selected. ADR report quality was evaluated using an ADR report quality evaluation system.
Results: None of the reports were rated as excellent and 1.40% (n = 16) as good. Report quality was better for new and serious reports than for general reports. Medical institutions generated higher quality reports than pharmaceutical manufacturers. Nurses generated higher quality reports than doctors, pharmacists, and other professionals. Reporters of different occupations showed significant differences in the quality of the indicators Reporting time limit, Intervention ADR time, ADR termination time, ADR intervention measures, Original disease, and Cause of medication (P = 0.000).
Conclusions: The ADR data quality was poor in western China, and of lower quality than reported data from previous research in other regions. Improvements in the quality and availability of ADR reports are urgently needed. 相似文献
Drug design and discovery studies are important because of the prevalence of diseases without available medical cures. New anticancer agents are particularly urgent because of the high mortality rate associated with cancer. A series of mononuclear gold (III) and platinum (II) complexes based on boronated phenylalanine (BPA) were designed and synthesized using 4,4’-dimethyl-2,2’-dipyridyl (L1) or 1,10-phenanthroline-5,6-dion (L2) ligands to obtain promising anticancer drug candidates. Proton nuclear magnetic resonance, infrared, mass spectrometry, and elemental analyses were utilized for chemical characterizations. Cell viability, cancer cell colony formation, endothelial tube formation, and cytoskeleton staining assays were performed using A549 lung adenocarcinoma and human umbilical vein endothelial cells (HUVECs) to investigate preliminary pharmacological activities. L1-based platinum (II) complex (BPA-L1-Pt) was the most promising complex, and has similar activity with the approved chemotherapy drug cis-platinum. Half maximal inhibitory concentration values for BPA-L1-Pt were 9.15 µM on A549s and 16.61 µM on HUVECs; the values for cis-platinum were 5.24 µM on A549s and 23.14 µM on HUVECs. Consequently, further synthesis studies should be performed to boost the cancer cell selectivity feature of BPA by varying metal and ligand types. 相似文献
