Objective To study the effect of graded intervention mode based on Pediatric Early Warning Score（PEWS）on the recovery process and respiratory function of children with severe pneumonia．Methods The clinical data of 100 children with severe pneumonia treated in our hospital from April 2021 to April 2023 were retrospectively analyzed．Those children were divided into study group（n=50）and control group（n=50）according to the difference of intervention methods．Conventional intervention was used in the two groups,and PEWS-based graded intervention was added to the study group．The two groups were compared with each other in terms of recovery process（including duration of symptoms and length of stay）,respiratory function（including ventilation velocity,maximum volume per minute,vital capacity,forced vital capacity and deep inspiratory capacity）,complications（including ventilators associated pneumonia,bullosa and pleurisy）,and family member satisfaction．Results The duration of symptoms and hospitalization days in the study group were shorter than those in the control group（all P<0.05）．The levels of respiratory function indexes in study group were higher than those in control group（all P<0.05）．There was no significant difference in the incidence of complications between the two groups（P>0.05）．The satisfaction of family member in the study group was higher than that in the control group（96.00% vs 82.00%）（P<0.05）．Conclusions The PEWS based graded intervention model has a good effect on promoting the rehabilitation process of children with severe pneumonia,and can improve respiratory function,and increase the satisfaction of family member of children with severe pneumonia．

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．

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．

Objective To explore the effect of immunotherapy combined with chemotherapy on lymphatic immunity and quality of life of patients with advanced non-small cell lung cancer（NSCLC）,and to provide reference for further clinical treatment. Methods A total of 120 patients with NSCLC from June 2021 to June 2023 were selected and divided into observation group and control group evenly according to the method of drawing lots,control group was treated with chemotherapy,the observation group was treated with immunotherapy combined with chemotherapy,and the clinical efficacy and adverse drug reactions were compared between the two groups．Before and after treatment,immune function（CD3⁺,CD4⁺,CD8⁺）,carbohydrate antigen 199（CA199）,carbohydrate antigen 125（CA125）,serum carcinoembryonic antigen（CEA）levels and health status questionnaire（QOL-RRB- scores）were measured．Results The total effective rate in the observation group was significantly higher than that in the control group（68.33%>41.67%,P<0.05）．After treatment,the ratios of CD3⁺ and CD4⁺ in the observation group were significantly higher than those before treatment and control group after treatment,and the ratio of CD8⁺ was significantly lower than that before and after treatment in the control group（P<0.05）．After treatment,the serum levels of CA199,CA125 and CEA in the observation group were lower than those before and after treatment in the control group（P<0.05）．The incidence of adverse drug reactions was 16.67% in the observation group and 36.67% in the control group,which was significantly lower in the observation group than in the control group（P<0.05）．After treatment,the QOL scores in the observation group were significantly higher than those in the control group and before treatment（P<0.05）．Conclusions Compared with chemotherapy alone,immunotherapy combined with chemotherapy can effectively reduce the levels of tumor markers,improve the immune indexes of patients,reduce the adverse drug reactions,and improve the efficacy and quality of life of patients with advanced NSCLC．
