ABSTRACT

Objective To explore risk factors of poor early prognosis in the treatment of COVID-19 by nematevir and ritonavir tablets Paxlovid and establish the prediction model to provide reference for improving the effect of such patients. Methods 92 inpatients of COVID-19 treated with Paxlovid in three military tertiary hospital in southern Fujian from January 2023 to March 2023 were retrospectively analyzed. The clinical indicators of 92 inpatients were collected for univariate and multivariate analysis by single factor and multiple factors and the independent risk factors of poor early prognosis in Paxlovid were screened out. Logistic model equation was transformed to construct the combined predictors, and ROC curve was used to determine the area under the curve (AUC) and the optimal critical value of the combined predictors. Results Among 92 patients, 31 (33.70%) developed poor early prognosis, including 11 deaths (35.48%), 17 critical cases (54.84%) and 3 severe cases (9.68%). Multi-factor Logistic regression analysis showed that the disease days, lymphocyte count, aspartate aminotransferase(AST), C reactive protein(CRP) and ventilator-assisted ventilation were independent risk factors for poor early prognosis in Paxlovid. A formula for calculating the combined predictors (Y) was established as Ycombinedpredictors=7.875Xdisease days+126.188Xlymphocyte count+1.438XAST+XCRP+220.500Xventilator-assisted ventilation based on the above independent risk factors, and the ROC curve was drawn. With the maximum area under the ROC curve of the combined predictors being 0.939, the prediction value was best, and the optimal critical value of the ROC curve corresponding to the maximum Youden index (0.756) was 447.920.Theoretical accuracy of the model was 89.10%. Conclusion The disease days, lymphocyte count, AST, CRP and ventilator-assisted ventilation were independent risk factors for poor early prognosis in Paxlovid. Combined predictors could be calculated by the above risk factors before medication. The efficiency should be improved by taking more active treatment, including combining with other anti-COVID-19 drugs when the prediction result exceeds 447.920.

ABSTRACT

Objective:To investigate the effect of lncRNA HOTAIR on the radiosensitivity of glioma cells and its underlying mechanism.Methods:The negative control plasmid, HOTAIR silencing plasmid, miR-NC over expressing plasmid, miR-17-5p over expressing plasmid were transfected into U87R cells, and assigned intothe silencing control, HOTAIR silencing, miR-NC over expressing and miR-17-5 pover expressing groups. Cells in the the above groups were irradiated at a dose of 4Gy, and recorded as silencing control+ 4Gy group, HOTAIRsilencing+ 4Gy group, miR-NC over expressing+ 4Gy group and miR-17-5p over expressing+ 4Gy group. The HOTAIR silencing plasmid, miR-NC suppressing plasmid and miR-17-5p suppressing plasmid were co-transfected into U87R cells and recorded as the HOTAIR silencing+ miR-NC suppressing group and HOTAIR silencing+ miR-17-5p suppressing group. All procedures were transfected by the liposome method. The expression of miR-17-5p and HOTAIR was detected by qRT-PCR. The radio sensitivity of glioma cells was evaluated by cell clone formation assay. The cell apoptosis was assessed by flow cytometry. The fluorescence activity was assessed by dual luciferase reporter assay.Results:HOTAIR was highly expressed in the radiation-resistant glioma cells. Silencing HOTAIR and over-expressing miR-17-5p could increase the radiosensitivity of U87R cells and promote radiation-induced apoptosis of U87R cells. HOTAIR could target and regulate the miR-17-5p expression. Suppressing miR-17-5p reversed the effect of silencing HOTAIR on U87R cell sensitization and promoting radiation-induced U87R cell apoptosis.Conclusions:Silencing lncRNA HOTAIR yields radiation sensitization and promotes radiation-induced apoptosis in glioma cells. The mechanism may be related to the regulation of miR-17-5p.

ABSTRACT

Objective To explore the localization of epileptogenic focus and select the appropriate surgical procedures for post-traumatic epilepsy. Methods The clinical data of 21 patients with post-traumatic epilepsy were studied retrospectively. Epileptogenic focus was located by comprehensively analyzing data of electro-neurophysiology, neurological imaging and clinical manifestation. Surgical procedures were performed in all patients, including resection of lesion and peripheral cortex in 12 patients, epileptogenie focus resection plus low power bipolar coagulation in five, anterior temporal iobectomy plus amygdalohippocampectomy in three and corpus callosotomy in one. Results All patients were followed up from 6 months to 3 years, which showed satisfactory outcome in eight patients, marked improvement in six, improvement in five and slight improvement in two. The total effective rate was 90%. Conclusions Surgical procedure is important for intractable post-traumatic epilepsy. The good efficacy depends on precise localization of epileptogenic focus and combined application of various surgical procedures.
