目的探讨小切口胆囊切除术治疗胆结石伴胆囊炎的效果。方法68例胆结石伴胆囊炎患者,采用随机数字表法分为对照组和实验组,每组34例。对照组行开腹胆囊切除术治疗,实验组行小切口胆囊切除术治疗。比较两组治疗前后疼痛介质因子指标(白细胞介素-6、心肌细胞P物质、前列腺素E2)、手术时间以及住院时间、并发症发生情况。结果术前,两组白细胞介素-6、心肌细胞P物质、前列腺素E2水平比较,差异无统计学意义(P>0.05);术后24 h,两组白细胞介素-6、心肌细胞P物质、前列腺素E2水平均显著高于术前,实验组白细胞介素-6(6.56±0.81)μg/ml、心肌细胞P物质(5.45±0.71)pg/ml、前列腺素E2(131.10±16.10)μg/ml均显著低于对照组的(8.82±0.91)μg/ml、(7.25±0.20)pg/ml、(181.34±24.45)μg/ml,差异具有统计学意义(P<0.05)。实验组手术时间(61.13±1.24)min以及住院时间(9.56±0.12)d均短于对照组的(75.31±2.75)min、(12.21±2.21)d,差异具有统计学意义(P<0.05)。实验组并发症发生率5.88%(2/34)低于对照组的29.41%(10/34),差异具有统计学意义(P<0.05)。结论胆结石伴胆囊炎患者实施小切口胆囊切除术治疗的效果确切,可改善患者病情,减少并发症,缩短治疗和康复时间,减轻对患者产生的不良应激。  相似文献

The frequency of primary small intestinal adenocarcinoma is increasing but is still low. Its frequency is approximately 3% of that of colorectal adenocarcinoma. Considering that the small intestine occupies 90% of the surface area of the gastrointestinal tract, small intestinal adenocarcinoma is very rare. The main site of small intestinal adenocarcinoma is the proximal small intestine. Based on this characteristic, dietary animal proteins/lipids and bile concentrations are implicated and reported to be involved in carcinogenesis. Since most nutrients are absorbed in the proximal small intestine, the effect of absorbable intestinal content is a suitable explanation for why small intestinal adenocarcinoma is more common in the proximal small intestine. The proportion of aerobic bacteria is high in the proximal small intestine, but the absolute number of bacteria is low. In addition, the length and density of villi are greater in the proximal small intestine. However, the involvement of villi is considered to be low because the number of small intestinal adenocarcinomas is much smaller than that of colorectal adenocarcinomas. On the other hand, the reason for the low incidence of small intestinal adenocarcinoma in the distal small intestine may be that immune organs reside there. Genetic and disease factors increase the likelihood of small intestinal adenocarcinoma. In carcinogenesis experiments in which the positions of the small and large intestines were exchanged, tumors still occurred in the large intestinal mucosa more often. In other words, the influence of the intestinal contents is small, and there is a large difference in epithelial properties between the small intestine and the large intestine. In conclusion, small intestinal adenocarcinoma is rare compared to large intestinal adenocarcinoma due to the nature of the epithelium. It is reasonable to assume that diet is a trigger for small intestinal adenocarcinoma.  相似文献

PLPPs (Phospholipid phosphatases) are widely expressed in different human tissues, regulate cell signal transduction, and are overexpressed in cancers such as gliomas, pancreatic adenocarcinoma, lung adenocarcinoma, and so on. As a member of the PLPP family, PLPP2 (phospholipid phosphatase 2) plays a vital role in the occurrence and development of breast cancer, but its mechanism is still unclear. Our research found that PLPP2 was overexpressed in breast cancer, and the higher expression level of PLPP2 showed a worse prognosis for breast cancer patients. Further analysis showed that overexpression of PLPP2 affected the expression of CDC34 (cell-division cycle 34), LSM7 (Like-Smith 7), and SGTA (small glutamine-rich tetratricopeptide repeat-containing protein alpha) through EMT (epigenetic-mesenchymal transition) related pathways to promote the occurrence and development of breast cancer. In vitro, silencing PLPP2 significantly reduced the proliferation, invasion, and migration abilities of human breast cancer cells MDA-MB-231. ER+ is a common subtype of breast cancer. Furthermore, we found that the overexpression of PLPP2 was significantly related to the poor prognosis of ER+ breast cancer. These results indicate that PLPP2 has value as a potential therapeutic target for breast cancer, especially for ER+ breast cancer.  相似文献

目的探讨异位胰腺的诊治,提高对该疾病的认识以减少误诊。方法回顾性分析 1例小肠异位胰腺病人的临床表现、诊断及治疗经过,结合文献分析其组织病理分型、临床表现和治疗经验。结果病人因“突发腹痛 1d”入院。入院后在全麻下急诊行开腹探查术,于术中见“小肠表面可及一肿物,肿物穿孔可见小肠内容物溢出”。术后病理证实肿物为异位胰腺。术后恢复满意,术后第 90天随访无并发症及影像学检查异常。结论异位胰腺属于一种先天性异常,缺乏特异性诊断方法,早期多无症状,因此可保守治疗;如有症状或术中意外发现为异位胰腺组织时,可手术切除。  相似文献

目的 研究关节镜下双后内侧入路单纯缝线联合经胫骨骨隧道二次固定治疗后交叉韧带胫骨止点撕脱骨折的临床效果。 方法 选取2018年5月至2020年8月收治的单纯后交叉韧带止点撕脱骨折16例,对其行关节镜下双后内入路单纯缝线复位固定联合经胫骨骨隧道二次固定技术,术后随访1年,对其临床治疗效果(Lysholm评分、IKDC评分及后抽屉试验)进行评价。 结果 手术顺利,术中无副损伤。术后1年后抽屉试验阴性,Lysholm膝关节功能评分(91.67±5.16)及IKDC评分(89.74±4.28)较术前明显增加,差异有统计学意义(P<0.05)。 结论 关节镜下双后内入路,应用单纯缝线联合经胫骨骨隧道二次固定技术治疗单纯后交叉韧带止点撕脱骨折临床效果肯定,值得普遍推广。  相似文献

B cell lymphoma 2 (BCL2) overexpression in a range of human tumors is often related to chemotherapy resistance and poor prognosis. GC-rich regions upstream of the P1 promoter in human BCL2 can form G-quadruplex (G4) structures through the stacking of four Hoogsteen-paired guanine bases. Stabilizing the G4 fold implies the inhibition of BCL2 expression and, thus, small molecules that selectively bind to the G4 are promising anticancer candidates. In this review, we discuss the structural aspects, binding affinity, selectivity, and biological activity of well-characterized BCL2 G4 binding ligands in vitro and in vivo. We also explore future directions in the research and development of G4-based anticancer therapeutics.  相似文献
