Application value of BIS and S100β combined with Copeptin in patients with acute severe carbon monoxide poisoning / 中华劳动卫生职业病杂志

Objective: To explore the application value of bispectral index(BIS) , specific protein 100β(S100β) combined with Copeptinin patients with acute severe carbon monoxide poisoning (ASCMP). Methods: A total of 256 patients with acute carbon monoxide poisoning admitted to Hengshui People's Hospital from June 2018 to June 2020 were collected, and they were divided into 30 mild cases, 40 moderate cases and 186 severe cases according to the degree of poisoning. Among them, patients with severe carbon monoxide poisoning were divided into a poor prognosis group (20 cases) and a good prognosis group (166 cases) according to whether adverse events occurred. The changes of creatine kinase isoenzyme (CK-MB) , N-terminal precursor B-type brain natriuretic peptide (NT-proBNP) , BIS, S100β, and Copeptin in poisoned patients were measured. Logistic regression analysis and receiver operating characteristic (ROC) curve were used to evaluate the significance of relevant indicators for ASCMP patients. Results: Compared with the mild-to-moderate group, CK-MB, NT-proBNP, S100β, Copeptin increased, and BIS value decreased in the severe group (P< 0.05). 24 hours after admission, compared with the good prognosis group, CK-MB, NT-proBNP, S100β, Copeptin in the poor prognosis group increased, and the BIS value decreased (P<0.05). In the poor prognosis group, CK-MB, NT-proBNP, S100β, and Copeptin at 72 hours after admission were all lower than those at 24 hours after admission, and the BIS value was higher than that at 24 hours after admission (P<0.05). Logistic regression analysis showed that ASCMP patients with increased S100β, Copeptin, and decreased BIS values had an increased risk of adverse events (P<0.05). The ROC curve showed that the area under the curve of the combined detection of BIS, S100β and Copeptin was 0.859, which had a great predictive value for the prognosis of ASCMP patients. Conclusion: BIS, S100β combined with Copeptin detection is of great value for early assessment of ASCMP disease and prognosis prediction.

Clinical Significance of P53, C-MYC and BCL-6 Abnormality in Patients with Diffuse Large B Cell Lymphoma / 中国实验血液学杂志

<p><b>OBJECTIVE</b>To study the clinical significance of P53, C-MYC and BCL-6 abnormality in the patients with diffuse large B cell lymphoma (DLBCL).</p><p><b>METHODS</b>From July 2011 to January 2013, 80 patients with DLBCL were admitted in our hospital and were chosen as study objects, their clinical data were collected. The abnormality of P53, C-MYC and BCL-6 was examined by using I-FISH for all the patients. The correlation of abnormality of P53, C-MYC and BCL-6 with clinical staging, curative efficacy and prognosis of the patients were analyzed.</p><p><b>RESULTS</b>Out of 80 patients 27 patients (33.75%) had P53 deletion, 24 patients (30.00%) had C-MYC rearrangement/amplification, and 46 patients (57.50%) had BCL-6 rearrangement. The P53 deletion, C-MYC rearrangement/amplification and BCL-6 rearrangement significantly correlated with staging, curative effect and prognosis of the patients (P < 0.05).</p><p><b>CONCLUSION</b>The curative efficacy and prognosis of the DLBCL patients with abnormality of P53, C-MYC and BCL-6 have been confirmed to be unsatisfactory.</p>
