OBJECTIVE:To compare the efficacy and safety of levonorgestrel intrauterine system and mifepristone in the treat-ment of perimenopausal dysfunctional uterine bleeding. METHODS:200 patients with perimenopausal dysfunctional uterine bleed-ing were randomly divided into observation group (100 cases) and control group (100 cases). Patients in the observation group placed levonorgestrel intrauterine system (containing levonorgestrel 52 mg),patients in control group received Mifepristone cap-sule 10 mg/d,oral,the treatment course for 2 groups were 3 months. Clinical efficacy,endometrial thickness,menstruation(PBAC score),hemoglobin level before and after treatment and incidence of adverse reaction in 2 groups were observed. RESULTS:After treatment,the total effective rate in observation group was significantly higher than control group,incidence of adverse reactions was significantly lower than control group,the differences were statistically significant(P<0.01). Before treatment,there were no significant differences in the endometrial thickness,PBAC score and hemoglobin level between 2 groups;after treatment,endome-trial thickness and PBAC score were significantly lower than before,and observation group was lower than control group;hemoglo-bin level was significantly higher than before,and observation group was higher than control group,the differences were statistical-ly significant(P<0.01 or P<0.05). CONCLUSIONS:The efficacy and safety of levonorgestrel intrauterine system are significant-ly superior to mifepristone in the treatment of perimenopausal dysfunctional uterine bleeding.

Objective To investigate the influence on the proliferation of the precursor cells from the inner ear of SD rats by different ages and growth factors in vitro .Methods The organs of utricle or saccule or cochlear Corti were isolated from different days’ SD rats born on different days(P1 ,P7 ,P14 ,P21 ,P30 ,P60) .From 12 SD rats of different age ,with 24 ears ,precursor cells were dissociated and cultivated under non -adherent conditions as single cell .We then counted the number of cell spheres under inverted phase contrast microscope .The results were statisti-cally anayzed and the quantity change curve of the same organ in different age rats were described until the single cells were cultured for 7 days .The culture medium was supplemented with defferent growth factor to observe the effects of the grow th factor on the number of cell spheres .Immunofluorescence assays were conducted for phenotype characterization .Results ① Some newly isolated single cells ,labeled by nestin ,were from each inner ear organ of rats(P1) .During 7 days in culture ,cells kept proliferation and formed suspended spheres ,which were expressed Br-dU and nestin positive .② The cell spheres could only formed from each cochlear Corti of rats (P1 ,P7) .But cell spheres that formed from each utricle or saccule were observed in a single saccule culture medium of all rats (P1~P60) .③The number of cell spheres ,which were formed by the isolated cells from inner ear organs of single utricle or saccule or cochlear Corti ,increased obviously in the presence of EGF or bFGF or IGF -1 ,but were not obviously in LIF .Statistically significant differences were seen between control group and every experimental group including EGF group ,bFGF group ,IGF-1 group(P<0 .01) ,but were not seen between control group and LIF group (P>0 .05) .Conclusion The highly proliferative cells were present in the vestibular organ (utricle or saccule) and cochle-ar Corti of SD rats .They could express the characterization of neural stem cell .As increase of the age ,the overall trend of proliferative capability is declining .Each of EGF and bFGF and IGF -1 possess the promoting effects for proliferation on the precursor cells alone ,which is not in present of LIF .

Objective The immature platelet fraction (IPF) could be detected quantificationally in Sysmex XE-2100 with the software of XE-pro and IPF master.The study aimed to perform the methodological evaluation of IPF detection and investigate the clinical significance for the monitoring for bone marrow hyperplasia in cancer chemotherapy patients.Methods The high-level, middle-level and low-level whole blood samples were randomly chosen for detection repeatly 20 times to obtain interrun coefficient of variation (CV) for evaluation of the precision and reproducibility. Integrated quality controls were determined for continuous 20 days to obtain intrarun CV, and the stability and carryover was investigated.Furthermore, the correlation between results from Sysmex XE-2100 and results from flow cytometry was assessed.182 healthy subjects and 130 cancer patients undergoing chemotherapy were selected and the latter were divided into two groups according to platelet counts after therapy, one was normal PLT group, the other was decreased PLT group.The IPF of either group was measured and was compared with each other.Results The precision of IPF for high-level, middle-level and low-level were 4.71%, 4.33% and 4.95%, respectively, they were less than 5%.The interrun CV of IPF detection for middle-level and low-level were less than 5%.The interrun CV of IPF detection for high-level were less than 10%.The carryover ranged from 0.6% to 2.7%,and the average rate was 1.2%.A good correlation for IPF detection was shown between results from Sysmex XE-2100 and flow cytometry(r = 0.880 9,P ＜ 0.01).Regarding clinical utility of IPF detection in treatment monitoring for chemotherapy effect, the median of IPF levels in decreased PLT group, normal PLT group,control group were 14.45% ,7.35% and 15.68%, respectively.There was significant difference among the three groups (H =49.032,P ＜0.01 ).The IPF level was higher in decreased PLT group than normal PLT group (t = -5.681, P ＜ 0.O1 ), and was lower in normal PLT group after chemotherapy than the control group (t = -6.662 ,P ＜0.01 ).Conclusions The determination of IPF by the Sysmex XE-2100 owns high precision and good stability. IPF is an effective marker for evaluation of thrombopoietic condition in the cancer chemotherapy patients.
