Objective To investigate the clinical significance of dynamic changes in the expression levels of tumor associated autoantibody(TAAB),including tumor protein 53(p53),protein gene product 9.5(PGP9.5),SRY-box containing gene 2(SOX2),G antigen 7 ATP-dependent RNA helicase(GAGE7),ATP-dependent RNA helicase(GBU4-5),melanoma antigen A1(MAGE A1),cancer/testis antigen(CAGE)in non-small cell lung cancer(NSCLC)patients before and after surgery.Methods Forty-one patients with NSCLC who underwent surgical treatment at the Department of Thoracic Surgery of Li Huili Hospital,Ningbo Medical Center,were selected from January 2019 to August 2022.Enzyme linked immunosorbent assay(ELISA)was used to detect the expression levels of seven TAAB markers in the serum of 41 NSCLC patients undergoing surgical treatment.Results The expression levels of PGP9.5 were found to be significantly higher in the squamous cancer group than in the adenocarcinoma group(P<0.05),while the expression levels of GAGE7 were found to be significantly higher in the adenocarcinoma group than in the squamous cancer group(P<0.05).The expression level of GBU4-5 was found to be significantly higher in the squamous carcinoma group than in the adenocarcinoma group at one week after surgery(Z=-2.095,P=0.036).Within the adenocarcinoma group,the expression levels of GBU4-5(P=0.027)and CAGE(P=0.042)were found to be significantly lower at one week after surgery compared with those before surgery.The expression levels of PGP9.5(P=0.004),GAGE7(P<0.001),and GBU4-5(P=0.014)were found to have decreased significantly at six months postoperatively in comparison to their preoperative levels.In the squamous cancer group,no statistically significant differences were observed in the expression levels at one week after surgery.The expression level of SOX2(P=0.011)exhibited a statistically significant decrease at six months postoperatively in comparison to the preoperative levels.Similarly,the expression level of GBU4-5 was found to be significantly decreased at one week postoperatively in comparison to the preoperative levels(P=0.009).The expression levels of PGP9.5(P=0.003),GAGE7(P=0.001),and GBU4-5(P=0.013)were found to have decreased significantly at six months postoperatively.Conclusion Surgical intervention can reduce the expression level of 7 TAABs in NSCLC patients.Monitoring 7 TAABs before and after surgical treatment is helpful to predict the surgical efficacy and postoperative disease progression of NSCLC patients.

Objective To summarize the experience of multi-disciplinary team(MDT)in the pediatric department of Qujing Maternal and Child Health Hospital,and to evaluate the effectiveness of MDT on neonatal brain injury.Methods The clinical data of children with brain injury and treated in the pediatrics department of Qujing Maternal and Child Health Hospital from November 2019 to April 2023 were collected.The children with brain injury and treated from October 2019 to June 2020 were regarded as the non-MDT group,and the children with brain injury and treated from July 2020 to April 2023 were regarded as the MDT group for comparative analysis.Chi-square test/t-test was used to compare and analyze the clinical data of the two groups.Results Among the 890 cases of pediatric brain injury,there were 519 males and 371 females.The median and quartiles of the age distribution for the two groups were as follows:MDT group 2.00(0.82,5.00)years and non-MDT group 1.00(1.00,4.00)years.Craniocerebral injury was the main type of brain injury in both groups,in addition,among children with craniocerebral injury and intracranial hemorrhage,the cure rate of MDT group was higher than that of non-MDT group,and the difference was statistically significant(P<0.05).Among the 405 children in MDT group,154(38.0%)underwent the surgery,while among the 485 children in non-MDT group,121(24.9%)underwent the surgery.The difference was statistically significant(P<0.05).23.2% of children in MDT group were in critical condition during the hospitalization,which was significantly lower than that in non-MDT group(30.5%),and the difference was statistically significant(P<0.05).The unhealed rate of MDT group(2.0%)was also significantly lower than that of non-MDT group(5.6%),the cure rate of MDT group(40.5%)was significantly higher than that of non-MDT group(34.4%),and there was a statistically significant difference(P<0.05).The expense of treatment,medicine and sanitary materials in MDT group were lower than those in non-MDT group,and the differences were statistically significant(P<0.05).The multivariate Logistic regression model analysis of the cure rate of children with brain injury showed that the MDT model could effectively improve the cure rate of children with brain injury(RR = 1.513,95% CI = 1.134-2.020).The results of multiple linear regression model analysis showed that there was no statistical difference in the effect of MDT on the actual hospitalization days of children(P>0.05).Conclusion Using MDT model to diagnose and treat children with brain injury is helpful to improve the cure rate,reduce the risk of children's disease aggravation,and achieve the significant therapeutic effects in children with brain injury.MDT model is worth popularizing and applying in children with brain injury.
