ABSTRACT
Objective:To observe the clinical effect of lower-reinforcing and upper-reducing acupuncture method for hyperplasia of mammary gland (HMG) and its influence on estradiol (E2) and progesterone (P).Methods:A randomized,single-blinded and controlled trial was conducted.A total of 124 cases conforming to the inclusion criteria were randomized by random number table into a treatment group and a control group,with 62 cases in each group.Patients in both groups received acupuncture therapy at the same acupoints,while patients in the treatment group received lower-reinforcing and upper-reducing method,and patients in the control group received even reinforcing-reducing manipulation.The treatment started around 10 d before menstruation and was conducted every other day.Patients received 5 treatments in each menstruation cycle for consecutive 3 cycles.The levels of E2,P and E2/P and clinical efficacy were measured before and after treatment.Results:After treatment,the breast lump size,pain intensity and concomitant symptoms score in both groups were substantially lower than those before treatment,showing statistical significances (all P＜0.01),and the improvement in the treatment group was higher than that in the control group,and the between-group comparisons showed statistical significances (all P＜0.01).After treatment,the overall effective rate was 91.9％ in the treatment group,higher than 72.6％ in the control group,and the between-group comparison showed a statistical significance (P＜0.01).After treatment,levels of E2,P and E2/P value showed no statistical significance when compared with those before treatment in the two groups (all P＞0.05).Conclusion:Lower-reinforcing and upper-reducing acupuncture method can effectively alleviate clinical symptoms and signs in HMG patients,and produce a better effect than even reinforcing-reducing manipulation.The majority of HMG patients' E2,P level and E2/P value were not beyond the normal ranges;therefore,acupuncture showed no substantial influence on E2 and P levels and E2/P value.
ABSTRACT
This study was aimed to explore the expression of survivin in leukemia cells and to investigate the effect of GM-CSF on survivin expression. The survivin expressions in 37 previously untreated leukemia patients and 10 normal persons as well as in three kinds of leukemia cell lines (K562, HL-60, U937) were analyzed by RT-PCR. The HL-60 cells were treated by the proper concentration of GM-CSF, and the changes of survivin mRNA and protein expression levels were detected by using RT-PCR and Western blot respectively. The results indicated that the positive rate of survivin gene in 37 leukemia patients was 67.6% (25/37) and significantly higher than that in normal control (20.0%). The expression level was higher in ALL cells than that in AML cells (73.3% vs 63.6%). Moreover, three kinds of leukemia cell lines all expressed survivin. After treating with the proper concentration of GM-CSF for 2 days, the expression of survivin obviously increased and the expression level of survivin mRNA was up-regulated by 26%, the expression level of survivin protein was up-regulated by 49%. It is concluded that the survivin gene extensively express in leukemia and its cell lines, and its expression can be obviously increased by GM-CSF.
