目的 本研究通过已建立的稳定表达人血小板CD36的HEK293T细胞系,制备鼠源的抗人CD36单克隆抗体并进行特性鉴定。方法 利用已经建立的稳定表达人血小板CD36的HEK293T细胞系对CD36(-/-)C57小鼠进行免疫,取脾脏与小鼠骨髓瘤细胞融合,筛选出阳性克隆。纯化单克隆抗体后,利用Western blot检测抗体结合活性。利用小鼠IgG类/单抗亚型鉴定试剂鉴定单克隆抗体的抗体亚型。通过流式细胞检测和血小板抗原单克隆抗体特异性免疫固定检测(MAIPA)鉴定其诊断应用价值。结果 经筛选后得到一株杂交瘤细胞,抗体亚型为IgG2a,轻链为κ链,Western blot试验表明该单克隆抗体特异性识别人血小板CD36抗原。MAIPA结果显示,与商业化单克隆抗体FA6-152相比,该单克隆抗体灵敏度更高。结论 成功制备了一种鼠抗人CD36单克隆抗体,为临床鉴定CD36抗体,筛选CD36阴性献血员提供了新的工具,也为今后进一步研究CD36在血液免疫疾病中作用机制提供了实验基础。
Objective In this study, by the established HEK293T cell line with stable expression of human platelet CD36, murine anti-human CD36 monoclonal antibody was prepared and characterized. Methods The established HEK293T cell line with stable expression of human platelet CD36 was used to immunize CD36 (-/-) C57 mice, and the spleen was fused with mouse myeloma cells to screen for positive cloning.After the purification of monoclonal antibody, the antibody binding activity was detected by Western blot.Mouse rapid antibody isotyping reagent was used to identify the subtype of monoclonal antibody.Its diagnostic value was evaluated by flow cytometry and monoclonal antibody-specific immobilization of platelet antigen (MAIPA). Results After screening, a high-producing hybridoma cell was obtained, the subtype of monoclonal antibody was IgG2a and the light chain was κ chain. Western blot analysis showed that the monoclonal antibody could specifically recognize CD36 antigen of human platelet. MAIPA results showed that the monoclonal antibody was more sensitive than the commercial monoclonal antibody FA6-152. Conclusion It is concluded that a mouse anti-human CD36 monoclonal antibody with biological activity has been obtained, which provides a new tool for the clinical identification of CD36 antibody and the screening of CD36 negative blood donors, and also provides an experimental basis for further research on the mechanism of CD36 in blood immune diseases.
目的 探讨入院准备中心制度在我院乳腺外科住院预约统筹管理的实践情况。方法 2017年1月—12月广州市第一人民医院入院准备中心对乳腺外科30张床位实施病床集中预约管理,依据患者病情进行预约,合理安排患者入院。结果 2017年1至12月我院乳腺外科共预约入院1225人/次,成功办理预入院1096人/次,约占乳腺外科总入院人数的77.85%。预入院进行手术患者415人/次,其中3日内手术患者为285人/次,预入院三日内手术率为68.67%。结论 预入院制度对乳腺外科病床进行集中预约管理能有效保证床位充分使用,为患者提供方便、有效的医疗服务,值得基层医院推广。
目的 探讨内镜下黏膜切除术患者肠道准备教育程序的优化方法及改善效果。方法 选择2022年12月—2023年12月广州市中西医结合医院接收的内镜下黏膜切除术患者180例进行研究,电脑随机编号按奇偶数分为两组各90例,对照组采取常规肠道准备教育工作,观察组实施基于优化的教育程序展开教育工作,比较两组依从性、肠道准备质量、满意度、不适症状发生情况。结果 观察组饮食依从率96.88%、服药依从率98.44%、运动依从率93.75%,均高于对照组的78.13%、79.69%、71.88%(χ 2 分别为6.172、7.745、7.120,P分别为0.012、0.005、0.007)。观察组左侧、横结肠、右侧等评分及肠道准备质量总分高于对照组(t分别为7.175、6.442、5.971、8.234,均P<0.001)。观察组肠道准备满意度为98.89%,高于对照组的88.89%(χ 2 =7.842,P=0.005)。观察组恶心11.11%、呕吐4.44%、腹胀5.56%、腹痛0.00%,低于对照组的22.22%、13.33%、14.44%、6.67%(χ 2 分别为4.000、4.390、3.950、4.310,P分别为0.045、0.036、0.046、0.037)。结论 对内镜下黏膜切除术患者实施基于优化的教育程序展开肠道准备教育工作可提高患者肠道准备依从性,保证良好的肠道准备质量和肠道清洁度,提高患者的满意度,有助减少肠道不适症状。
Objective To explore the optimization method and improvement effect of bowel preparation education program in patients undergoing endoscopic mucosal resection.Methods A total of 180 patients with endoscopic mucosal resection admitted to the hospital from December 2022 to December 2023 were selected for the study.They were randomly divided into two groups with 90 cases in each group.The control group was given routine bowel preparation education,and the observation group was given education based on optimized education procedures.The compliance,quality of bowel preparation,satisfaction and discomfort symptoms were compared between the two groups.Results The diet compliance rate 96.88%,medication compliance rate 98.44%,exercise compliance rate 93.75% in the observation group were significantly higher than 78.13%,79.69%,71.88% in the control group(χ 2 =6.172,7.745,7.120,P=0.012,0.005,0.007).The scores of left colon,transverse colon and right colon and the total score of bowel preparation quality in the observation group were significantly higher than those in the control group(t=7.175,6.442,5.971,8.234,all P<0.001).The satisfaction of bowel preparation in the observation group(98.89%)was significantly higher than that in the control group(88.89%)(χ 2 =7.842,P=0.005).Nausea 11.11%,vomiting 4.44%,abdominal distension 5.56%,abdominal pain 0.00% in the observation group were significantly lower than 22.22%,13.33%,14.44%,6.67% in the control group(χ 2 =4.000,4.390,3.950,4.310,P=0.045,0.036,0.046,0.037).Conclusions The implementation of bowel preparation education based on optimized education program in patients undergoing endoscopic mucosal resection can improve the compliance of bowel preparation,ensure good quality of bowel preparation and bowel cleanliness,improve patient satisfaction,and reduce the occurrence of intestinal discomfort symptoms,which is worthy of promotion.
