The test results of serum T cell subsets of these cases showed that most of the cases had different degrees of decline in the levels of CD3⁺, CD4⁺, CD8⁺ and CD4⁺/CD8⁺. Among them, CD3⁺ levels decreased in 6 cases, CD4⁺ levels decreased in 16 cases, CD8⁺ levels decreased in 17 cases, CD4⁺ and CD8⁺ levels decreased in 14 cases, and CD3⁺, CD4⁺, and CD8⁺ levels decreased in 4 cases; total cell number of BALF was (3 673.1±377.9)×10⁶/L, the proportion of macrophages was (23.6±17.6)%, lymphocytes had (22.1±16.2)%, and neutrophils had (46.5±24.8)%. Conclusions Pathogenic analysis showed that the main pathogen of BALF in children with severe pneumonia is Mycoplasma pneumoniae, and the detection of serum T cell subsets mostly showed a decrease in CD4⁺ and CD8⁺ levels.

Results No matter before or after chemotherapy, there was a transmural gradient in each layer of myocardium. Compared with those before chemotherapy, the absolute values of myocardial strain parameters of each layer were reduced after chemotherapy, and GLSendo and GCSendo and ΔGLS decreased more significantly (P<0.05),while the area under the ROC curve of GLSendo was 0.766, P<0.001.Selecting 25.3% as the diagnostic boundary, the sensitivity was 83.3%, and the specificity was 70%.The area under the ROC curve of ΔGLS was 0.749, P<0.001. Selecting 4.1% as the diagnostic boundary, the sensitivity was 76.7%, and the specificity was 73.3%. Conclusions The myocardial layer-specific strain analysis is helpful for early detection of changes in the myocardial function of the left ventricle, which caused by mFOLFOX6 in patients with colorectal cancer. GLSendo and ΔGLS are sensitive indicators in this technique.

Objective To explore the prognostic significance of ferroptosis related lncRNAs in patients with lung squamous cell carcinoma. Methods Data of 551 lung squamous cell carcinoma cases was downloaded from the Cancer Genome Atlas (TCGA) of the United States, including 49 normal control samples and 502 lung squamous cell carcinoma samples. The lncRNAs co-expressed with genes related to ferroptosis was screened out. Univariate Cox regression was used to further screen out the lncRNAs. Then, Lasso regression and multiple Cox regression were used to construct lncRNA models related to ferroptosis. A model-based risk score system was established and Cox regression was used to test whether it was an independent prognostic factor. The functional enrichment of ferroptosis related lncRNAs were visualized using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes. Results The four prognostic ferroptosis related lncRNAs (AC253536.6, FLJ46906 LUCAT, AC022150.2) were significantly different, and the ferroptosis lncRNAs model was constrncted with them. This model divided lung squamous cell carcinoma patients into low-risk group and high-risk group. The model-based risk score was a significant independent factor for patients with lung squamous cell carcinoma (HR=2.116, 95% CI=1.513-2.961; P<0.001). In addition, the four lncRNAs were significantly enriched in metabolism and tumor classical pathways during the ferroptosis process. Conclusions The four ferroptosis lncRNAs could be molecular biomarkers and therapeutic targets for patients with lung squamous cell carcinoma.

Methods A total of 92 patients with locally advanced cervical cancer treated in our hospital were randomly divided into study group and control group, with 46 cases in each group. The control group received intensity-modulated radiation therapy (IMRT) combined with platinum chemotherapy and the study group received ART combined with platinum chemotherapy. After 8 weeks of treatment, the clinical effects of the two groups were compared. The levels of tumor markers [carcinoembryonic antigen (CEA) and squamous cell carcinoma associated antigen (SCC-Ag)] were compared between the two groups before and after treatment. The incidence of adverse reactions in the two groups was compared with the grading standard of Acute Radiation Injury Group (RTOG) and Common Terminology Criteria for Adverse Events (CTCAE).
