Objective: The aim of this study was to improve the direct results of reconstructive surgery in patients operated on for complicated forms of colorectal cancer, by using 5-fluorouracil in the postoperative period. Methods: The study involved 126 patients (they were divided into 2 groups) with colorectal cancer, who underwent reconstructive surgery. They underwent a standard clinical examination and a mandatory examination program. Results: The use of 5-fluorouracil in adjuvant treatment in patients with colorectal cancer significantly reduces the number of subjective clinical manifestations (positional tests) in the main group – 17%, and in the control group – 54.3%, as well as objective clinical manifestations (instrumental research methods) in Group I – 13%, and Group II – 89.5%, respectively. The study shows that in re-operated patients with colorectal cancer who received 5-fluorouracil, abdominal adhesions are characterized by a low content of collagen and fibroblasts, low vascularization and a high content of polymerized fibrin strands. It was also found that re-operated patients with colorectal cancer who did not receive 5-fluorouracil, abdominal adhesions are characterized by a high collagen content, a large number of fibroblasts, and severe angiogenesis. Conclusion: It was found that the prolonged administration of 5-fluorouracil statistically significantly reduces the risk of adhesions, thereby showing the effectiveness of preventing adhesive disease of the abdominal organs. It was shown that the prolonged administration of 5-fluorouracil significantly reduces the number of subjective and objective signs of adhesive disease of the abdominal organs, as well as significantly decreases intraoperative and postoperative complications, the duration of the operation, and the amount of blood loss. In the postoperative period, it reduces the length of hospital stay and improves the quality of life of patients.  相似文献

目的 探讨重度与非重度宫腔粘连(IUA)患者各项临床指标之间的差异。方法 收集经宫腔镜确诊IUA的118例患者的临床资料,根据IUA AFS评分标准将患者分为重度IUA组(重度组,41例)和轻中度IUA组(非重度组,77例),并分析2组患者各项临床指标间的差异。结果 与非重度组患者比较,重度组患者的孕次较多、2次以上清宫史者比例较高、宫腔镜电切操作次数较多(P均< 0.05)。2组中人工流产术后、宫腔镜下电切术后、子宫动脉栓塞术联合清宫术后宫腔操作史者比例比较差异均有统计学意义(P均< 0.05)。重度组患者中宫腔操作次数 ≥3次者比例(85%)高于非重度组(P < 0.05);重度组患者中经阴道彩色多普勒超声提示宫腔异常(回声不均、连续性中断、显示不清或粘连)者的比例高于非重度组(P < 0.05)。结论 人工流产术、宫腔镜下电切术和子宫动脉栓塞后清宫术可增加IUA发生的风险,经阴道彩色多普勒超声对重度IUA有较好的诊断价值。  相似文献

Breast cancer (BC) is a highly metastatic, pathological cancer that significantly affects women worldwide. The mortality rate of BC is related to its heterogeneity, aggressive phenotype, and metastasis. Recent studies have highlighted that the tumor microenvironment (TME) is critical for the interplay between metastasis mediators in BC. BC stem cells, tumor-derived exosomes, circulatory tumor cells (CTCs), and signaling pathways dynamically remodel the TME and promote metastasis. This review examines the cellular and molecular mechanisms governing the epithelial to mesenchymal transition (EMT) that facilitate metastasis. This review also discusses the role of cancer stem cells (CSCs), tumor-derived exosomes, and CTs in promoting BC metastasis. Furthermore, the review emphasizes major signaling pathways that mediate metastasis in BC. Finally, the interplay among CSCs, exosomes, and CTCs in mediating metastasis have been highlighted. Therefore, understanding the molecular cues that mediate the association of CSCs, exosomes, and CTCs in TME helps to optimize systemic therapy to target metastatic BC.  相似文献

ObjectiveTo explore the hemostatic mechanism of Jianpi Yiqi Shexue decoction (JYSD) by regulating vascular factors in an immune thrombocytopenia (ITP) mouse model.MethodsAn ITP mouse model was established by the passive-immune modeling method, and interventional drugs used were prednisone tablets and JYSD. The platelet count; vascular activity–related factors vWF, VCAM-1, and TM; and VEGF and bFGF were used as observational indicators.ResultsOn the 8th day of administration, compared with the model group, platelet counts in the prednisone and JYSD groups increased (both P < .001). Compared with the control group, the levels of vWF, VCAM-1, and TM in the other groups were lower (all P < .05). The VCAM-1 level in the JYSD group was higher than that in the prednisone group (P = .012), but without significant difference compared with the model group (P = .051). The TM level in the JYSD group was the lowest (vs. the model group, P = .047; vs. the prednisone group, P = .006). Compared with the control group, the IOD values of VEGF and bFGF in the other three groups were lower (all P < .01). The IOD values of VEGF in the prednisone and JYSD groups were both higher than those in the model group (P = .002 and P < .001, respectively). The IOD values of bFGF among the model, prednisone, and JYSD groups were not statistically significant (P > .05).ConclusionA vascular factor disorder is involved in the pathogenesis of ITP. JYSD can increase the platelet count, upregulate VEGF expression, and reduce the TM level. JYSD has the same effect as prednisone tablets in regulating platelet, vWF, VEGF, and bFGF, with a stronger effect in normalizing VCAM-1 and TM levels. The hemostatic mechanism of JYSD is closely related to the effective balance of vascular factors.  相似文献

目的探讨常规超声与超声造影对宫腔病变的诊断价值。 方法选取自2018年12月14日至2020年12月10日在北京大学人民医院妇科超声检查室就诊并提示宫腔病变的患者55例。常规二维超声根据宫腔病灶回声、大小及血流信号初步判断病变性质,再于宫腔镜手术前行超声造影检查,以正常宫壁做对照,根据病变区造影剂到达时间、峰值强度及消退时间对病变做出良恶性判断。以病理结果为金标准,分析比较常规超声与超声造影对宫腔病变的诊断效能,以及宫腔良、恶性病变超声造影模式差异。 结果宫腔镜术后病理诊断良性病变36例;恶性病变19例。以术后病理为金标准,常规二维超声诊断病变良恶性的准确性为47.3%,敏感度63.2%、特异度73.7%、阳性预测值70.6%、阴性预测值93.3%;超声造影诊断病变良恶性的准确性为89.1%,敏感度89.5%、特异度88.9%、阳性预测值81.0%、阴性预测值94.1%。常规超声诊断结果与病理诊断不符合的6例患者中,5例超声造影诊断结果与病理相符合。常规二维超声无法明确诊断的23例患者中,20例超声造影诊断结果与病理相符合,超声造影对该23例的诊断敏感度为83.3%(5/6),特异度为88.2%(15/17)。恶性病变以早增强(84.2%,16/19)、高增强(78.9%,15/19)和早消退(89.5%,17/19)为主,早-高-早及早-高-同造影模式均为恶性病例,占比73.7%(14/19)。良性病变以同步增强及晚增强为主,占94.4%(34/36),其中晚-低-同模式分布最多,为13例。 结论超声造影可弥补单一采用常规二维超声的不足,二者联合应用可提高宫腔病变诊断准确性。  相似文献

宫腔镜下宫腔粘连分离术是治疗宫腔粘连的最常用方法,但术后粘连复发率高,妊娠结局不理想,因此术后常需联合辅助治疗措施改善预后。传统辅助治疗措施主要包括物理屏障以及口服或局部应用药物等,其中宫内放置Foley导管常与口服雌激素联合应用,因其疗效稳定、性价比高等优点在临床上应用已久。近年来以生物制剂和生物材料为基础的多种新型辅助治疗措施逐渐应用于宫腔粘连分离术后,其中富血小板血浆和干细胞等生物制剂在促进子宫内膜修复、改善生殖结局等方面显示出了更好的治疗效果。此外,基于凝胶、支架等生物材料的新型辅助治疗措施也显示出了良好的治疗作用,为难治性宫腔粘连带来了希望。综述宫腔粘连分离术后传统及新型辅助治疗措施的研究进展,为宫腔粘连的综合治疗提供新的临床思路。  相似文献

ObjectivesTo investigate the effect of a protective coating on the surface characteristics, flexural properties, cytotoxicity, and microbial adhesion of vat-photopolymerization additive-manufacturing denture base polymers.MethodsThe specimens were additively manufactured using digital light processing (DLP). Specimen surfaces were coated with the same printed resin, and mechanical polishing was used for comparison. Surface topography, arithmetical mean height (Sa), and water contact angle values were measured. Furthermore, flexural strength (FS)/modulus and fractography were evaluated. Also, cytotoxicity was evaluated by an extract test. Finally, an adhesion test was used to investigate the adhesion of mixed oral bacteria to the specimens.ResultsThe Sa values in the polished (0.26 ± 0.08 µm) and coated (0.38 ± 0.14 µm) groups were significantly lower than in the untreated (2.21 ± 0.42 µm) and control (2.01 ± 0.37 µm) groups. The coating treatment resulted in a higher FS compared to the untreated surface (p = 0.0002). After the coating treatment, no significant differences were found in relative cell viability between the groups (p > 0.05). The quantitative results showed significantly higher bacterial adhesion in the untreated group than in the polished (p = 0.0047) and coated (p < 0.0001) groups.SignificanceThe surface characteristics and flexural properties were optimized by the protective coating. Also, the protective coating did not adversely affect cytocompatibility. Moreover, the coating treatment could effectively decrease oral bacteria adhering to the surfaces. Therefore, the protective coating treatment can be a less time-consuming alternative to mechanical polishing as a post-processing procedure for the digital denture.  相似文献
