Methods A total of 110 elderly patients with chronic heart failure admitted to our hospital were selected,with a time interval of January 2023 to March 2024．Serum SCD-1 and sVEGFR-2 levels were detected and follow-up investigations were conducted to understand their re hospitalization and cardiogenic death due to heart failure．Multiple logistic regression analysis was used to explore the prognostic factors affecting elderly patients with chronic heart failure. Results According to logistic retrospective analysis,heart function grading（OR=3.433,95%CI：0.934-6.431）,elevated B-type brain natriuretic peptide（OR=2.462,95%CI：0.861-4.765）,elevated serum SCD-1（OR=3.795,95%CI：0.972-6.894）,and elevated serum sVEGFR-2（OR=3.842,95%CI：0.942-6.912）were important factors affecting the poor prognosis of elderly patients with chronic heart failure,with differences P<0.05．The area under the curve of combined serum SCD-1 and sVEGFR-2 was 0.962,and the area under the curve of B-type brain peptide sodium was 0.844,which was significantly higher than that of a single SCD-1 curve of 0.658 and sVEGFR-2 curve of 0.712,with a difference of P<0.05. Conclusions Research has confirmed that the prognosis of elderly patients with chronic heart failure is not satisfied,and their serum SCD-1 and sVEGFR-2 monitoring levels are abnormally elevated,which is related to the poor prognosis of elderly patients with chronic heart failure．It can be regarded as the main biomarker for defining the prognosis of elderly patients with chronic heart failure．

Objective To explore the occurrence and influencing factors of acute adverse reactions of iodine contrast agents in enhanced computed tomography（CT）. Methods A retrospective analysis was conducted on 100 patients admitted to our hospital from October 2020 to October 2023 who experienced acute adverse reactions to iodine contrast agents during CT enhancement．They were divided into an observation group and another 100 patients who underwent CT enhancement examination in our hospital during the same period without any adverse reactions were selected as the control group．The acute adverse reactions of iodine contrast agent in the observation group of patients were analyzed,the clinical data and injection of iodine contrast agent between the two groups of patients were compared,and include acute adverse reactions as the dependent variable（occurrence of acute adverse reactions=1,absence of acute adverse reactions=0）was used in the Logistic regression model to analyze the independent influencing factors of acute adverse reactions of CT enhanced iodine contrast agent．Results Among the 100 patients who experienced acute adverse reactions to iodine contrast agents,65 were mild reactions,accounting for 65.00%,34 cases had were moderate reactions,accounting for 34.00%,and one cases had severe reactions,accounting for 1.00%．There was no significant difference between the observation group and the control group in gender,age,body mass index（BMI）,history of hypertension,diabetes,heart dysfunction,hyperthyroidism,coronary heart disease,use of iodine contrast agent,and food allergy（P>0.05）．The history of asthma（9.00% vs 2.00%）,renal insufficiency（13.00% vs 3.00%）,adverse reactions of iodine contrast（21.00 % vs 2.00%）,pollen allergy（12.00% vs 4.00%）,drug allergy（26.00% vs 7.00%）and other allergies（10.00 % vs 2.00%）were significantly different（χ²=4.710,P=0.030;χ²=6.790,P=0.009;χ²=17.740,P<0.001;χ²=4.350,P=0.037;χ²=13.100,P<0.001;χ²=5.670,P=0.017）．There was no significant difference in the dosage of iodine contrast agent between the observation group and the control group（P>0.05）．The injection rate of iodine contrast agent between the observation group and the control group（< 3 mL/min was 55.00% vs 69.00%;≥3 mL/min was 45.00% vs 31.00%）,and the types of iodoxanol （iodoxanol[34.00% vs 34.00%],iodoxanol[47.00% vs 30.00%],iodohexanol[19.00% vs 36.00%]） were significantly different（χ²=4.160,P=0.041;χ²=9.010,P=0.011）．History of renal insufficiency,adverse reactions to iodine contrast agents,drug allergies,other allergies,and injection speed of iodine contrast agents were independent risk factors for the occurrence of acute adverse reactions to iodine contrast agents（P<0.05）．Conclusions Acute adverse reactions to iodinated contrast agents in CT enhancement are mostly mild．Previous history of renal insufficiency,history of adverse reactions to iodinated contrast agents,history of drug allergies,other allergic histories,and high injection speed of iodinated contrast agents may be influencing factors for the occurrence of adverse reactions to iodinated contrast agents．

目的 分析贝伐珠单抗与化疗对晚期结直肠癌患者4种错配修复蛋白（MSH2、MLHI、MSH6、PMS2）水平影响。方法 选择2022年1月—2024年1月江苏省宿迁市中医院肿瘤科102例晚期结直肠癌患者,按抽签法分成两组,即化疗组及联合组,各51例。化疗组应用FOLFOX（亚叶酸钙+奥沙利铂+氟尿嘧啶）方案进行化疗,联合组采取贝伐珠单抗联合FOLFOX方案治疗。对比其肿瘤控制效果、免疫功能及MSH2、MLHI、MSH6和PMS2水平变化,并对比组间不良反应发生率。结果 联合组客观缓解率、疾病控制率高于化疗组（P<0.05）;治疗后联合组患者CD4⁺、CD3⁺、CD8⁺、和CD4⁺/CD8⁺数值高于化疗组,且两组治疗后均低于治疗前（P<0.05）;治疗后两组患者MSH2、MLHI、MSH6和PMS2缺失率对比无统计学意义（P>0.05）,但其阳性、阴性表达情况对比差异有统计学意义,联合组MSH2、MLHI、MSH6和PMS2阳性率低于化疗组（P<0.05）;两组不良反应发生率对比差异无统计学意义（P>0.05）。结论 对晚期结直肠癌在化疗基础上增加贝伐珠单抗抗肿瘤效果显著,改善其免疫功能,虽无法改善患者错配修复蛋白缺损,但可辅助降低其阳性率,且不影响安全性。

Objective To analyze the effects of bevacizumab and chemotherapy on the levels of four mismatch repair proteins（MSH2,MLHI,MSH6,PMS2）in patients with advanced colorectal cancer. Methods A total of 102 patients with advanced colorectal cancer from the Oncology Department of Suqian Traditional Chinese Medicine Hospital in Jiangsu Province from January 2022 to January 2024 were selected,and were divided into two groups according to the drawing method,namely the chemotherapy group and the combination group,with 51 patients in each group．The chemotherapy group received FOLFOX（calcium folinate+oxaliplatin+fluorouracil）regimen for chemotherapy,while the combination group received bevacizumab combined with FOLFOX regimen for treatment．Tumor control effect,immune function,and changes in MSH2,MLHI,MSH6,and PMS2 levels,and its incidence of adverse reactions were compared．Results The objective remission rate and disease control rate of the combined group were higher than those of the chemotherapy group（P<0.05）．After treatment,the CD4⁺,CD3⁺,CD8⁺ and CD4⁺/CD8⁺ values in the combination group were higher than those in the chemotherapy group,and those after treatment were lower than those before treatment in both groups（P<0.05）．After treatment,there were no significant differences in the deletion rates of MSH2,MLHI,MSH6,and PMS2 between the two groups of patients（P>0.05）,but there was a significant difference in their positive and negative expression．The positive rates of MSH2,MLHI,MSH6,and PMS2 in the combination group were lower than those in the chemotherapy group（P<0.05）．There was no significant difference in the incidence of adverse reactions between the two groups（P>0.05）．Conclusions Adding bevacizumab on the basis of chemotherapy has a significant anti-tumor effect on advanced colorectal cancer,improving its immune function．Although it cannot improve the mismatch repair protein defect in patients,it can assist in reducing its positivity rate and has high safety．
