ABSTRACT
Abstract Objective: To explore the changes and clinical significance of serum Neuron-Specific Enolase (NSE) and Squamous Cell Carcinoma antigen (SCC) in patients with lung cancer before and after radiotherapy. Methods: 82 patients with lung cancer were treated with radiotherapy, and effective clinical intervention was given during the radiotherapy process. The patients were followed up for 1 year after radiotherapy and were divided into a recurrence and metastasis group (n = 28) and a non-recurrence and metastasis group (n = 54) according to their prognosis. Another 54 healthy volunteers examined in the present study's hospital during the same period were selected as the control group. To compare the changes of NSE and SCC levels in serum in patients with lung cancer at admission and after radiotherapy, and to explore their clinical significance. Results: After intervention, NSE and SCC levels in the serum of the two groups of patients were significantly lower than those before intervention, and the levels of CD4+ and CD4+/CD8+ were significantly higher than those before intervention (p < 0.05); the level of CD8+ was not significantly different from that before intervention (p > 0.05). And NSE and SCC levels in the intervention group were significantly lower than those in the routine group, the levels of CD4+, CD4+/CD8+ were significantly higher than those in the routine group (p < 0.05). Conclusion: NSE and SCC in serum can preliminarily evaluate the effect of radiotherapy in patients with lung cancer and have a certain predictive effect on prognosis.
ABSTRACT
Objective:To evaluate the efficacy of omeprazole and cimetidine in the prophylaxis of stress ulcer bleeding to provide evidence for clinical therapy in China. Methods:The randomized controlled trials were searched in PubMed, Medline, CNKI, Wan-fang and Vip database with the key words of omeprazole, cimetidine and stress ulcer. Two evaluators assessed the quality and reviewed the data independently. RevMan 5. 2 software was used for Meta-analysis. Results:Seventeen randomized controlled trials were includ-ed involving 892 patients for omeprazole group and 888 patients for cimetidine group. The results of Meta-analysis showed that the difference between the two groups after the treatment was statistically significant by comparing the incidence of stress ulcer bleeding (OR=0. 23,95% CI:0. 17-0. 32;P<0. 000 01). The incidence of stress ulcer bleeding of omeprazole group was significantly lower than that of cimetidine group. Conclusion:Existing literature analysis shows that omeprazole is more effective than cimetidine in the stress ulcer bleeding prophylaxis.
