Résumé

OBJECTIVE To investigate the protective effect of curcumin on Aβ1-42 damaged cells. METHODS SH-SY5Y cells were cultured with Aβ1-4210μmol · L-1 in the absence or presence of curcumin 1, 5 or 10 μmol · L-1. Cell viability was assayed by MTT. Cell membrane damage was detected by the concentration of lactate dehydrogenase (LDH) in culture medium. Cell apoptosis was measured by flow cytometry with Annexin Ⅴ-FITC/PI staining. Mitochondrial membrane potential was characterized by fluorescence of JC-1 dye. Enzymatic activity of caspases-9 and-3 was measured by colorimetric assay. Protein expression of caspase-3 was detected by Western blotting. RESULTS Compared with vehicle control, the cell viability, concentration of LDH and both early and late apoptosis in Aβ1-4210 μmol · L-1 damaged group were decreased(P<0.01). However, the cell viability, release of LDH and both early and late apoptosis in curcumin group were promoted compared with that in Aβ1-4210μmol·L-1 damaged group. Curcumin inhibited Aβ1-42-induced depolarization of mitochondrial membrane potential(P<0.01), and attenuated Aβ1-42-induced activation of both caspases9 and caspases3 in a concentration-dependent manner, respectively(r=0.990, P<0.01; r=0.996, P<0.01). There were no significant differences in the above detected indexes between curcumin 10 μmol · L-1 group and vehicle control group. CONCLUSION Curcumin inhibits Aβ1-42-induced cell damage and apoptosis by promoting mitochondrial membrane potential and depressing the activation of caspases.

Résumé

Objective To explore the feasibility of combining anterior and posterior fontanelle acoustic windows for fetal median sagittal plane cranial scanning in prenatal ultrasound.Methods From July 5 to August 25 in 2012,200 pregnant women in Huai'an First Hospital at 22 to 24 gestational weeks accepted transabdominal uhrasonography,with anterior fontanelle,longitudinal suture and posterior fontanelle as acoustic windows to obtain the median sagittal plane.In the mean time,ten aborted or induced fetuses (with malformations or maternal complications) underwent cranial ultrasound with the same acoustic windows.The successful rates of obtaining median sagittal plane were calculated.Data were analyzed by Chi-square test.Results (1) Among the ten aborted or induced fetuses,all median sagittal planes were successfully obtained through anterior,posterior fontanelle,or longitudinal suture alone.(2) Among the 200 cases of prenatal uhrasonography,the successful rate of obtaining median sagittal plane through posterior fontanelle alone was 76.0%(152/200),which was higher than that through anterior fontanelle alone [59.5% (119/200),x2=12.5,P<0.01].The successful rate was 95.5% (191/200) when combining the anterior and posterior fontanelle,which was higher than that through anterior fontanelle or posterior fontanelle alone (x2 =74.3 and 31.1,both P<0.01).The successful rate of obtaining median sagittal plane through posterior fontanelle was 67.3% (65/102) in cephalic presentation,which was also higher than that through anterior fontanelle [37.3% (38/102),x2 =14.3,P<0.01].The successful rate was 88.8% (87/98) through posterior fontanelle in non-cephalic presentation,which was similar to that through anterior fontanelle [82.7%(81/98),x2 =1.5,P>0.05].When both anterior and posterior fontanelle applied,the successful rate in cephalic presentation was 9.8% (10/102),lower than that in non-cephalic presentation fetuses [71.4% (70/98),x2 =79.1,P<0.01].Conclusions The successful rate in obtaining median sagittal plane through posterior fontanelle is higher than that through anterior fontanelle,and might be increased when both anterior and posterior fontanelle were used.

Résumé

Objective To Investigate the effectiveness of transobturator inside-out tension-free urethral suspension for the treatment of female stress urinary incontinence. Methods Eighteen cases were operated on with urethral suspension by using transobturator artificial meshes from August 2005 to February 2006. Dissection was performed alongside the urethra bilaterally by way of the anterior vaginal wall. A transobturator mesh was passed through the vulva and was positioned without tension underneath the urethra. Results The operative time ranged 10~25 min (mean, 15?3 min), and the estimate blood loss was 10~20 ml (mean, 15?2 ml). An indwelling catheter had been used for 3 d because of urinary retention in 1 case. All of the patients were successfully cured and normal voiding without complications was achieved postoperatively during 6 months of follow-up. Conclusions Transobturator inside-out tension-free urethral suspension is simple and minimally invasive, with low complication rate and little risk of bladder injury. It is a safe and effective technique for the surgical treatment of female urinary stress incontinence.
