[Effects of miR-203a targeting and its target gene on lymph node metastasis of breast cancer].

To study the expression and correlation of mir-203a and its target gene ATM in breast cancer tissues, so as to provide theoretical basis for the pathogenesis of breast cancer, especially lymph node metastasis. Thirty paired breast cancer and paracancer normal tissues were collected, and RT-qPCR was used to detect the relative expression levels of mir-203a and ATM in the samples of the two groups. Correlation analysis was conducted for mir-203a and ATM, and correlation analysis was conducted for the pathological characteristics, so as to compare whether there were statistical differences between mir-203a and ATM in lymph node metastasis and non-metastasis.

[Predictive significance of exhaled breath temperature for airway inflammation changes in children with asthma].

Objective: To explore the predictive significance of exhaled breath temperature (EBT) for airway inflammation changes in children with asthma.

Methods: A total of 60 children with asthma who met the inclusion criteria at the first visit were chosen as the asthma group, and 60 healthy children were selected as the control group. The EBT level was measured by the latest third-generation product (X-halo).
