RESUMO
Objective:To investigate the effect of immunotherapy with dendritic cells and cytokine-induced killer cells combined with chemotherapy on apoptosis-related genes and immune function in patients with middle- and advanced-stage non-small cell lung cancer.Methods:A total of 100 patients with middle- and advanced-stage non-small cell lung cancer who received treatment in Taizhou Hospital of Zhejiang Province, Wenzhou Medical University, China from February 2018 to May 2019 were included in this study. They were randomly divided into control and observation groups ( n = 50/group). The two groups were given chemotherapy with pemetrexed and cisplatin. The observation group was given immunotherapy with dendritic cells and cytokine-induced killer cells based on chemotherapy with pemetrexed and cisplatin. Changes in apoptosis-related genes [primary autosomal recessive microcephaly gene (MCPH1), ataxia-telangiectasia mutated (ATM), ataxia telangiectasia mutated and Rad3 related (ATR), transcription factor 21 (TCF21)] and immune function were monitored. Clinical efficacy of immunotherapy with dendritic cells and cytokine-induced killer cells combined with chemotherapy with pemetrexed and cisplatin in the treatment middle-and advanced-stage non-small cell lung cancer was assessed. Results:After treatment, expression of MCPH1, ATM, ATR and TCF21 in the observation group was 301.11 ± 41.12, 239.98 ± 30.15, 270.01 ± 36.01, 270.01 ± 34.02, respectively, which was significantly higher than that in the control group [101.32 ± 15.32, 103.00 ± 13.97, 101.12 ± 14.90, 100.20 ± 14.99, t = 32.194, 29.149, 30.644, 32.299, all P < 0.001]. The proportion of the number of Th1-positive cells in the number of CD +4 T cells in the observation group was significantly higher than that in the control group [(29.00 ± 3.41)% vs. (22.61 ± 3.22)%, t = 9.634, P < 0.001]. The proportion of the number of Th17-,Th2 and CD +4CD +25Treg-positive cells in the number of CD +4 T cells in the observation group were (0.89 ± 0.10)%, (12.01 ± 1.36)%, (11.02 ± 1.92)%, respectively, which were significantly lower than those in the control group [(1.70 ± 0.20)%, (17.61 ± 2.20)%, (18.70 ± 2.40%)%, t = 25.614, 15.310, 17.670, all P < 0.001]. Total effective rate in the observation group was significantly higher than that in the control group [52.0% (26/50) vs. 30.0% (15/50), χ2 = 5.002, P < 0.05]. Conclusion:Immunotherapy with dendritic cells and cytokine-induced killer cells combined with chemotherapy with pemetrexed and cisplatin can induce apoptosis and regulate immune function. The combined therapy exhibits better clinical efficacy in the treatment of non-small cell lung than chemotherapy alone.
RESUMO
The liver injury caused by drug and / or its metabolites is one of the most common reasons for drugs to be withdrawn or disapproved.Premarketing clinical evaluation of drug-induced liver injury (DILI) is extremely important to drug evaluation.Signals of DILI and Hyman's Law (Hy's Law),clinical evaluation and lessons of DILI were discussed to help developing new drugs.
RESUMO
Objective To study the analepsia effect of high and low dose sevoflurane combined with propofol anesthesia in partial hepatectomy.Methods 64 patients with partial hepatectomy were selected as the subjects.They were randomly divided into low concentration group and high concentration group,32 patients in each group.The two groups were treated with sevoflurane combined with propofol anesthesia,low concentration group was given 0.5MAC sevoflurane,high concentration group was given 1.0MAC sevoflurane.The clinical results were compared between the two groups.Results The time of propofol use,postoperative recovery time,extubation time and improved Aldrete score of 9 min in the high concentration group were(765.83±342.86)mg,(21.39±8.23)min,(41.81±8.37)min and(30.24±9.63)min,respectively,which were significantly lower than those in the low concentration group [(1 143.64±374.64)mg,(25.46±7.98)min,(46.68±7.73)min and(35.94±8.89)min,respectively,t=4.208,0.008,2.418,2.460,all P<0.05].In addition,the OAA/S scores at T0,T1of the high concentration group were(3.83±0.64)points and(4.28±0.85)points,respectively,which were significantly higher than those of the control group[(3.36±0.76)points and(3.79±0.87)points],the differences between the two groups were statistically significant(t=2.676,2.279,all P<0.05).Conclusion The combination of sevoflurane and propofol in patients with partial hepatectomy can reduce the dosage of propofol and shorten the recovery time of postoperative spontaneous breathing in patients,and contribute to improve the quality of patients'' recovery.
