BACKGROUNDTo explore the therapeutic effect of bronchial artery infusion chemotherapy combined with immunotherapy for lung cancer with malignant hydrothorax.

METHODSSeventy-five lung cancer patients with malignant hydrothorax were randomly divided into the two groups: 38 patients were given intrathoracic chemotherapy and bronchial artery infusion chemotherapy combined with immunotherapy as observing group; 37cases only received intrathoracic chemotherapy as control group. Chi-square assay was performed to analyze the efficacy (responses for lung cancer and hydrothorax control) after the first course of treatment and the 1-, 2-year survival rates in the two groups.

RESULTSAfter the first course of treatment, the total responses for lung cancer were 31.58% (12/38) and 5.41% (2/37) in the observing group and control group (Chi-square=8.46, P < 0.01) respectively ; and responses for hydrothorax control were 86.84% and 64.86% respectively (Chi-square= 4.96, P <0.05). The 1- and 2-year survival rates in the observing group were 65.79% (25/38) and 26.32% (10/38) respectively, which were significantly higher than those of the control group (40.54% and 5.41%) respectively (Chi-square=4.80, P <0.05; Chi-square=6.10, P <0.05).

CONCLUSIONSThe intrathoracic chemotherapy combined with bronchial artery infusion chemotherapy and immunotherapy is quite effective in the treatment of lung cancer with malignant hydrothorax.

Objective:To explore the effect of problem-oriented evidence-based nursing on postoperative neurological complications in patients with aortic dissection aneurysm (ADA) .Methods:Using the convenient sampling method, a total of 82 ADA patients who underwent surgical treatment in Henan Provincial People's Hospital were selected as the research objects from September 2018 to May 2020. They were randomly divided into the study group and the control group, with 41 cases in each group. The control group was given routine nursing intervention, while the study group was given problem-oriented evidence-based nursing intervention based on routine nursing. The incidence of postoperative neurological complications in ADA patients was compared between the two groups.Results:The incidence of postoperative neurological complications in the study group was 4.88% (2/41) , lower than 24.39% (10/41) in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:The problem-oriented evidence-based nursing model can effectively reduce the incidence of postoperative neurological complications in ADA patients.
