Objective:To explore the effect of outpatient nursing interventions on the hypoglycemic treatment and psychological emotions of diabetic patients.Methods:148 patients who came to our hospital for outpatient treatment ...Objective:To explore the effect of outpatient nursing interventions on the hypoglycemic treatment and psychological emotions of diabetic patients.Methods:148 patients who came to our hospital for outpatient treatment from February 2022 to October 2023 were selected and divided into a control group and an observation group,with 74 cases per group,according to the random number table method.The control group received routine nursing intervention,and the observation group received outpatient nursing intervention based on the control group.The two groups were observed for their effects of hypoglycemic treatment and psychological and emotional improvement before and after outpatient nursing intervention.Results:The health behavior scores of the control group were lower than that of the observation group;the post-intervention fasting blood glucose,2h postprandial blood glucose,anxiety self-rating scale(SAS),and the depression self-rating scale(SDS)of the control group were significantly higher than that of the observation group,and the difference was statistically significant(P<0.01).Conclusion:Outpatient nursing intervention encouraged patients to comply with healthy behaviors and helped control blood sugar levels.Patients’anxiety,depression,and other adverse psychological states were also improved hence the outpatient nursing intervention is worthy of further promotion.展开更多
目的探讨肉瘤样肾细胞癌组织中PD-L1的表达及肿瘤内微血管密度情况,为肉瘤样肾细胞癌免疫治疗及靶向治疗方案的选择提供理论依据。方法通过免疫组化法检测PD-L1、CD31及CD34在16例肉瘤样肾细胞癌(癌成分均为透明细胞肾细胞癌)中的表达,...目的探讨肉瘤样肾细胞癌组织中PD-L1的表达及肿瘤内微血管密度情况,为肉瘤样肾细胞癌免疫治疗及靶向治疗方案的选择提供理论依据。方法通过免疫组化法检测PD-L1、CD31及CD34在16例肉瘤样肾细胞癌(癌成分均为透明细胞肾细胞癌)中的表达,并评估肿瘤微血管密度。结果16例肿瘤中CD31和CD34免疫组化染色显示,肉瘤样肾细胞癌区域微血管密度明显高于不伴肉瘤样分化的区域,微血管密度计数分别为68.6±25.8 vs 38.7±16.0(t=3.931,P=0.0005)和69.5±28.1 vs 40.1±18.4(t=3.506,P=0.0015),差异有统计学意义。肉瘤样区域PD-L1表达水平高于非肉瘤样区域,CPS分别为34.7±26.9和25.9±27.6,但差异无统计学意义。结论在肉瘤样肾细胞癌中,肉瘤样区域微血管密度和PD-L1表达水平明显高于非肉瘤样区域,提示靶向治疗联合免疫治疗可能为此类肿瘤提供一种有效的治疗方法。展开更多
目的:探讨血小板与白细胞比值(platelet and white blood cells ratio, PWR)、血小板与淋巴细胞比值(platelet and lymphocyte ratio, PLR)、中性粒细胞与淋巴细胞比值(neutrophil to lymphocyte ratio, NLR)以及尿白细胞计数(urinary l...目的:探讨血小板与白细胞比值(platelet and white blood cells ratio, PWR)、血小板与淋巴细胞比值(platelet and lymphocyte ratio, PLR)、中性粒细胞与淋巴细胞比值(neutrophil to lymphocyte ratio, NLR)以及尿白细胞计数(urinary leucocyte count, ULEU)与接受PD-1抑制剂治疗晚期尿路上皮癌(urothelial carcinoma, UC)患者预后的关系。方法:收集78例接受PD-1抑制剂治疗晚期UC患者的临床资料,利用Kaplan-Meier法计算生存率和Log-rank检验比较不同组间的生存差异,同时采用COX回归分析预后影响因素。结果:低PLR组与高PLR组的1年生存率分别为71.98%和47.63%,差异有统计学意义(P<0.05);低NLR组与高NLR组的1年生存率分别为71.36%和48.15%,差异有统计学意义(P<0.05);PWR高低两组和ULEU状态预测UC患者生存率无显著性差异(P>0.05)。单因素回归分析结果显示,N分期、M分期、TNM分期、远处转移个数、PLR、NLR是影响晚期UC患者生存情况的危险因素(P<0.05)。多因素回归分析显示,PLR是影响接受PD-1抑制剂治疗的UC患者预后的独立因素。结论:PLR、NLR为影响接受PD-1抑制剂治疗晚期UC患者预后的独立因素,PLR高值组和NLR高值组患者的预后较PLR低值组和NLR低值组的患者差。展开更多
