RESUMO
Objective:To investigate the clinical efficacy of compound Huangdai tablets combined with all-trans retinoic acid in the treatment of acute promyelocytic leukemia. Methods:A total of 120 patients with acute promyelocytic leukemia who received treatment in the First People's Hospital of Huzhou, China between February 2013 and February 2015 were included in this study. They were randomly assigned to receive either all-trans retinoic acid, mercaptopurine and methotrexate in combination (control group, n = 60) or all-trans retinoic acid combined with compound Huangdai tablets (study group, n = 60). The time to hemoglobin rebounding, the time to platelet count rebounding, and the time to first complete remission were recorded. The recurrence and death of patients during 5 years of follow up were recorded. Adverse drug reactions during the treatment period were recorded. Results:The time to hemoglobin rebounding, the time to platelet count rebounding, and the time to first complete remission in the study group were (19.56 ± 2.61) days, (20.42 ± 2.73) days, (1.74 ± 0.45) months, respectively, which were significantly shorter than those in the control group [(28.42 ± 3.85) days, (30.63 ± 4.02) days, (3.31 ± 0.69) months, t = 10.328, 9.746, 8.521, P < 0.001]. The 1-year and 5-year recurrence rate in the study group were 11.37% and 21.67% respectively, which were significantly lower than those in the control group [28.33%, 41.67%, χ2 = 5.208, 5.546, P = 0.022, 0.019]. 5-year mortality rate in the study group was significantly lower than that in the control group [8.33% vs. 25.00%, χ2 = 6.000, P = 0.014]. There was no significant difference in adverse drug reaction between study and control group [28.33% vs. 26.67%, χ2 = 0.042, P = 0.838]. Conclusion:Compound Huangdai tablets combined with all-trans retinoic acid can effectively shorten the remission time of acute promyelocytic leukemia, reduces the disease recurrence rate and mortality rate, and is highly safe.
RESUMO
Objective To analyze the changes of CD4+ T cell numbers at different periods of antiviral therapy in HIV-infected and AIDS patients (HIV/AIDS) in Yichang City. Methods The relevant information was retrieved from the National AIDS Comprehensive Prevention Information System-Antiretroviral Treatment Management Database. Changes in the number of CD4+ T cells were analyzed in HIV/AIDS patients who started receiving highly active antiretroviral therapy (HAART) and continued the treatment for 3 years from January 1, 2003 to December 31, 2017 in Yichang. Results The number of CD4+T lymphocytes in 550 HIV/AIDS cases increased significantly at various time points within 3 years after treatment, and increased with the increase of treatment time（F=100.20，P<0.001）. The CD4+T cell counts of different baseline level groups were statistically different before and after treatment（F=8.57，P<0.01）. The CD4+ T cell counts of patients who started treatment at age of 15-30 years old increased faster than those who started treatment at age of over 30 years old（F=1.27，P<0.05）. Conclusion HAART has a significant effect on the increase of CD4+T cells, and the early treatment is more effective. Early detection, diagnosis and treatment should be promoted, and anti-viral treatment should be actively carried out.
RESUMO
Objective To explore the effect of arsenic trioxide maintenance therapy on the long-term recur-rence rate in patients with acute promyelocytic leukemia ( APL ) . Methods From December 2011 to December 2013,60 patients with APL in the First People's Hospital of Huzhou were selected and divided into control group and observation group according to random number table, with 30 cases in each group. All patients received the same induction therapy and consolidation therapy. During the maintenance treatment period, all - trans retinoic acid ( ATRA) was given to the control group,and arsenic trioxide was used in the observation group. The serum levels and incidence of adverse reactions in the two groups were detected and compared after two cycles of the maintenance therapy. Three years of follow - up was conducted after treatment to record and compare the recurrence rate and survival rate in the two groups. Results The levels of TC and TG after 1 and 2 cycles of treatment were higher than those before treatment in both two groups(all P<0. 05),but the levels of lipid indicators in the observation group were lower than those in the control group,and the differences were statistically significant (t=2. 044,2. 175,all P<0. 05). The incidence rates of retinoic acid syndrome,elevated intracranial pressure and other adverse reactions in the observation group during the treatment were lower than those in the control group(6. 67％ vs. 26. 67％,6. 67％ vs. 30. 00％,6. 67％ vs. 26. 67％),and the differences were statistically significant(χ2 =0. 043,0. 023,0. 043,all P<0. 05). The survival rates after 2 and 3 years of treatment in the observation group were higher than those in the control group(90. 00％ vs. 66. 67％,83. 33％ vs. 60. 00％),and the differences were statistically significant(χ2 =4. 812,4. 812,all P<0. 05). The recurrence rate after 3 years of treatment in the observation group was lower than that in the control group(10. 00％ vs. 33. 33％),and the difference was statistically significant(χ2 =4. 812,P <0. 05). Conclusion For patients with APL, the application of arsenic trioxide in the maintenance therapy can produce no significant effect on their lipid metabolism, and at a certain extent, can help reduce the incidence of adverse reactions and recurrence rate,and improve the survival rate.
