ABSTRACT
Objective To study the changes of urodynamics of middle-aged(35-55 years old)female patients with urinary incontinence and improve the diagnosis and treatment.Methods Analyze and compare the urodynamics between 56 cases of middle-aged female patients with urinary incontinence and 17 cases of normal control.Results Among the 56 patients,33 cases with stress incontinence(SUI group 58.93％),9 cases with urgency urinary incontinence(UUI group 16.07％),14 cases with mixed urinary incontinence(SUI/UUI group 25.00％).There was significant difference on maximum flow rate(Qmax[27.72 ± 5.21]ml/s vs[20.45 ±7.15]ml/s,P ＜0.05)between the SUI group and control group.The beginning of a sense of capacity(FS),normal urination feeling(ND),strong feeling of urination(SD)and urgent urination feeling(UD)were (135.65 ± 42.73)ml,(166.24 ± 51.42)ml,(315.75 ±42.34)ml,(320.24 ± 45.03)ml and(132.70 ±40.65)ml,(160.70 ± 50.44)ml,(320.75 ± 42.34)ml,(335.75 ± 51.98)ml in the UUI group and control group respectively.And there were significant differences on the four indexes between UUI group and control group(P ＜ 0.05).There was significant difference on ALPP([62.29 ± 25.40]cm H2O vs[88.30 ± 28.54]cm H2O,P ＜0.05)between the SUI group and SUI/UUI group.Pressure at maximum flow rate(Pdet-Qmax,[24.29 ± 6.24]cm H2O vs[34.45 ± 8.20]cm H2 O,maximum urethral pressure(M UP([68.20 ± 18.27]cm H2O vs[87.14 ± 17.26]cm H2O)and maximum urethral closure pressure(MUCP([74.24 ±35.75]cm H2O vs[90.66 ±30.10]cm H2O)in SUI group were significantly lower than those in control group(P ＜0.05)Conclusion There were large groups of middle-aged female urinary incontinence in patients and the classification is more complex.It shows important guiding significance for diagnosis and selecting proper treatments by detecting urodynamic.
ABSTRACT
Purpose:To study the growth suppressing effect of sodium butyrate(NaB) on human ovarian carcinoma KK cells and endometrial carcinoma HHUA cells and its mechanism, as well as its potential as a new antitumor agent. Methods:Human endometrial carcinoma cell line HHUA and ovarian carcinoma cell line KK were cultured in vitro and exposed to sodium butyrate. The changes of morphology and chromatin induced by NaB were investigated by means of HE staining and DNA fluorescent staining, respectively. Cell cycle distribution and apoptosis were quantified by using flow cytometric analysis. Apoptotic degradation of DNA was analyzed by extracting DNA and separated by electrophoresis through a 2% agarose gel. Western blotting analysis was carried out to determine the expression of PARP, Fas, Bax and Bcl 2 proteins.Results:NaB arrested HHUA and KK cells at G 1 phase at the low concentration (≤2 mol/L), after 24 hours treatment. The percentage of G 1 phase was up to 70%. While at the medium concentration (4 mol/L and 10 mol/L), both HHUA and KK cells manifested typical apoptotic morphological and chromatic features. High concentration (≥10 mol/L) caused cell necrosis. NaB could upregulate Fas protein expression in HHUA, whereas the levels of Bcl 2 and Bax proteins remained unchanged. Conclusions:NaB may suppress the growth of HHUA and KK cells through arrest of cell cycle and induction of apoptosis. The responses of cells to NaB vary at the different concentrations. NaB induces cell cycle arrest at low concentration and induces apoptosis at medium concentration. The inhibition of NaB on cell growth is in a time and dose dependent manner. Upregulation of Fas protein may be the mechanism of apoptosis induction in HHUA cells. The effects of NaB on HHUA and KK cell growth suggest that NaB may be a new therapeutic agent in cancer treatment.
