ABSTRACT
Objective To observe the effects of the Diaomo-Zhibeng liquid on the expression of Bcl-2/Bax mRNA and their protein in vitro endometrial glandular epithelial cells in patients of endometrial hyperplasia Methods The endometrial tissue in patients with the pathological diagnosis of endometrial hyperplasia were collected.After isolation,culture and identification,the endometrial cells were divided into four groups:low dosage group (12.5 μg/ml),middle dosage group (25 μg/ml),high dosage group (50μg/ml) and blank control group at randomaccording to the random number table.Three duplicate samples were set for each group.After 48h,the expression of Bcl-2 and Bax were detected by RT-PCR and Western-blot.Results Compared with the blank control group,the expression of Bcl-2 mRNA (1.51 ± 0.07,1.09 ± 0.06,0.93 ± 0.07 vs.1.92 ± 0.08) and protein (0.91 ± 0.02,0.72 ± 0.03,0.62 ± 0.03 vs.1.28 ± 0.02) significantly decreased,while the expression ofBax mRNA (5.73 ± 0.37,8.00 ± 0.23,10.72 ± 0.40 vs.3.27 ± 0.34) and protein (0.45 ± 0.02,0.63 ± 0.02,0.78 ± 0.03 vs.0.32 ± 0.02) sifnificantly promoted in low dosage group,medium dosage group and high dosage group of Diaomo-Zhibeng liquid (P＜0.05).Compared with low dosage group,the expression of Bcl-2 mRNA and protein significantly decreased in middle and high dose group (P＜0.05),but Bax mRNA and protein significantly increased (P＜0.05).Conclusions The Diaomo-Zhibeng liquid can increase the susceptibility of epithelial cells to apoptosis,regulate the balance of cell proliferation and apoptosis tends to apoptosis,have the effect of accelerating cells apoptosis.
ABSTRACT
Objective To investigate the effects of lobaplatin on proliferation and invasion of cervical cancer CaSki cells.Methods Human cervical cancer CaSki cells were randomly divided into blank control group,2,6 and 12 μg/ml lobaplatin groups by random number table method.The proliferations of the cells were detected by methyl thiazolyl tetrazolium (MTT).The morphological changes of the cells were observed by inverted microscope.The invasive abilities of the cells were detected by Transwell invasion test.The protein expressions of extracellular signal-regulated kinase (ERK) and phospho-extracellular signal-regulated kinase (p-ERK) were detected by Western blotting.Results The absorbance (A) values of blank group,2,6,12 μg/ml lobaplatin groups cultured for 24 h were 0.513 ± 0.023,0.428 ± 0.014,0.380 ± 0.012 and 0.300 ± 0.013 respectively,those of the cells cultured for 48 h were 0.831 ± 0.024,0.558 ± 0.019,0.415 ± 0.015 and 0.088 ±0.009 respectively,and those of the cells cultured for 72 h were 1.153 ±0.022,0.572 ± 0.023,0.201 ± 0.017 and 0.052 ± 0.014 respectively.The differences were statistically significant (F =12.922,P ＜ 0.001;F =10.192,P ＜ 0.001;F =11.192,P ＜ 0.001),and the differences between each two groups were statistically significant (all P ＜ 0.05).Under inverted microscope,the cells of the platinum groups were shrunken and round,the volume and quantity were reduced,the morphology was irregular,the gap was increased,and the changes were more obvious with the increase of the concentration and the culture time.The numbers of penetrating cells of the blank group,2,6,12 μg/ml lobaplatin groups were 87.27 ±9.38,71.02 ± 8.92,53.20 ± 10.02 and 21.02 ± 7.37 respectively.The difference was statistically significant (F =87.291,P ＜ 0.001),and the differences between each two groups were statistically significant (all P ＜ 0.05).The A values of ERK protein in the blank group,2,6,12 μ~ml lobaplatin groups (0.955 ± 0.021、0.953 ± 0.023、0.950 ± 0.020、0.951 ±0.022)showed no significant difference (F =2.033,P =0.783),but the A values of p-ERK protein in the four groups were 0.941 ±0.015,0.831 ±0.020,0.620 ±0.019 and 0.493 ±0.017 respectively,which showed significant difference (F =11.921,P ＜0.001),and the differences between each two groups were statistically significant (all P ＜ 0.05).Conclusion Lobaplatin can inhibit the proliferation and invasion of cervical cancer CaSki cells,which may be related to the inhibition of the expression of p-ERK protein.
ABSTRACT
Objective:To observe the feasibility of promoting blood circulation by removing blood stasis in target interfering ADUB endometrial hyperplasia.Methods:Endometrial hyperplasia model was established,and the rats were divided into normal group(group A),model group(group B),small,middle and large dosage groups of Chinese drugs(C group,D group,E group,respectively).To observe uterus humid weight,uterus index,morphological change of endometria and expression of VEGF before and after treatment.In addition,30 cases of Anovulatory dysfunctional uterine bleeding were selected and given intrauterine injection of Qumozhibeng Cream twice in the first week after menstrual period,the change of menstrual blood amount were observed after applying medicine for one month,three months and six months.Results:After treatment,the uterus humid weight and uterus index decreased(P
