Objective:To evaluate the diagnostic value and safety of transbronchial lung biopsy and bronchoalveolar lavage (BAL) in pulmonary complications in patients with hematological tumors.Methods:A retrospective analysis was performed on 68 patients with hematological tumors combined with lung lesions from The University of Hong Kong-Shenzhen Hospital and The Third People's Hospital of Shenzhen from May 2016 to May 2022, including 37 males, 31 females, with a median age of 56 years (age range 21-90 years), among which 20 patients were >65 years old. Diagnostic fiberoptic bronchoscopy was performed with signs including fever, cough, hypoxemia, hemoptysis, unexplained dyspnea, and imaging changes. Patients with pulmonary masses were evaluated for transbronchial lung biopsy, including inner and outer leaf mass and high-density shadow of lung leaves, pathological and special staining of biopsy tissue (Grocott staining), BAL acquisition of bronchoalveolar lavage fluid (BALF) for microbiological smear/culture, cytomegalovirus, Pneumocystis jirovecii and Mycobacterium tuberculosis (TB) smear, TB DNA, TB and fungal culture. Etiological analysis of pulmonary complications and observation of the complications associated with fiberoptic bronchoscopy in patients with hematological tumors were conducted. Results:BALF test was performed in all patients after bronchoscopy, bronchoscopic lung tissue biopsy was performed in 46 cases. The total number of confirmed pathogenic infections was 40, including 12 cases of fungal infections, 9 cases of bacterial infections (2 cases each of E. faecalis and Pseudomonas aeruginosa, 1 case of Staphylococcus aureus, 1 case of Klebsiella pneumoniae, 1 case of E. coli, 1 case of coagulase-negative Staphylococcus, and 1 case of Streptococcus mitis), 9 cases of viral infection (5 cases of cytomegalovirus, 3 cases of parainfluenza virus type Ⅲ, and 1 case of respiratory syncytial virus), 4 confirmed cases of Pneumocystis jirovecii pneumonia, 3 cases of suspected mixed infection of Pneumocystis jirovecii and fungi, 1 case of Cryptococcus, 2 cases of suspected TB infection. No pathogenic organisms were found in 28 cases, including 6 cases of mechanized pneumonia, 6 cases associated with a history of hematological tumors, and 16 cases of other unidentified pathogens. All patients did not experience death or other serious complications caused by bronchoscopy complications. Conclusion:Pulmonary complications are common in patients with hematological tumors, and the application of transbronchial lung biopsy has good safety. Early examination of fiberoptic bronchoscopy can provide pathogenic diagnostic evidence of bacterial, fungal, Pneumocystis jirovecii and viral infections, thus improving the diagnostic rate.

Objective:To explore the expression of family with sequence similarity 83 member A (FAM83A) in colorectal cancer, and the effect of FAM83A knockdown on the proliferation of colorectal cancer cells and the related mechanism.Methods:The expression of FAM83A in the tissues of 102 patients with colorectal cancer and its adjacent tissues was detected by immunohistochemistry. HCT116 cells were divided into experimental group and control group. The experimental group cells were transfected with FAM83A-siRNA plasmid, and the control group cells were transfected with MOCK-siRNA plasmid. The mRNA content of FAM83A in each group was detected by fluorescence quantitative PCR. The expressions of FAM83A, P13K, p-AKT and p-mTOR in each group were detected by Western blot. CCK8 assay and clonogenesis assay were used to detect cell proliferation.Results:The positive rate of FAM83A in colorectal cancer patients was 88.23% (90 cases /102 cases), and the expression rate of FAM83A in paracancer tissues was 10.78% (11 cases /102 cases). The expression rate of Fam83a in colorectal cancer tissues was significantly higher than that in paracancer tissues, with statistical significance ( P<0.001). After siRNA transfection, the mRNA expression levels of FAM83A in HCT116 cells of the experimental group and control group were 1.23±0.20 and 0.43±0.12, respectively, and the protein expression levels of FAM83A were 1.19±0.11 and 0.23±0.08, respectively. The expression levels of P13K were 1.21±0.17 and 0.28±0.09, the expression levels of p-AKT were 1.35±0.23 and 0.57±0.18, and the expression levels of p-mTOR were 1.48±0.20 and 1.05±0.14. The expression of P13K, p-Akt and p-mTOR was down-regulated (all P<0.05). The absorbance of HCT116 cells in the experimental group and the control group was 1.09±0.22 and 2.21±0.27, respectively. The cloning rate of HCT116 cells in the experimental group and the control group was 21.6%±2.4% and 62.7%±4.1%, respectively. The proliferation ability of HCT116 cells in the experimental group decreased significantly ( P<0.05) . Conclusions:The expression of FAM83A is significantly increased in colorectal cancer tissues, which may be related to the malignant degree of colorectal cancer. FAM83A affects the proliferation of colorectal cancer cells through the P13K/AKT/mTOR signaling pathway.
