Chinese Journal of Obstetrics and Gynecology 2008;43(11):835-838
Objective To investigate the effect of ginsenoside-Rgl on paraurethral fascia fibroblastsmultiplication and the expression of proliferation cell nuclear antigen (PCNA) of stress urinary incontinence(SUI) women in vitro. Methods Specimens of human paraurethral fascia were obtained from 4 SUI womenduring tension-free vaginal tape (TVT) or tension-free vaginal tape-obturator (TVT-O) procedure.Fibroblasts were isolated and cultured by outgrowth technique. After reaching confluency fibroblasts weresubcultured every 5 days and cells after passage number 3 to 5 were used for assessment. The paraurethralfascia fibroblasts were treated with ginsenoside-Rgl at different concentrations (5, 10, 20 μmol/L) andfibroblnsts without Rgl were used as controL The multiplication conditions of paraurethral fascia fibroblastswere respectively detected by methyl thiazolyl tetrazolium (MTr) assay and the expression of PCNA byhistochemistry. Results ( 1 ) Compared with the control group, the growth rate of cells treated with differentconcentrations of Rgl after 72h [ (29±5 )%, (40±5 )%, (26±4)% respectively ] was significantly higher(P<0.01). (2)Compared with the control group, the stimulatory effect of Rgl on fibroblast growth wassignificant at 24 h (P<0.01), and peaked at 72 hi (29±5)% ,(40±5)%, (26±4)% respectively, P<0.01]. (3)Compared with the control group(28.77% ), there was a significant increase of PCNA-positivecells (P<0.01) after 48 h treatment with different concentrations of Rgl (49.24%, 83.48%, 54.50%respectively). Conclusion The results indicate that, at least in vitro, fibroblasts from paraurethral fasciataken from women suffering from SUI are able to proliferate after

Chinese Journal of Postgraduates of Medicine 2010;33(3):1-3
Objective To determine quantity of type Ⅰ collagen and mRNA expression of decorin and transforming growth factor (TGF)- β_1 in the upper portion of the anterior vagina in women with pelvic organ prolapse (POP). Methods Transvaginat biopsies were obtained from the anterior vaginal wall in 27 POP(POP group) and 21 non-poP(control group). The concentration of type Ⅰ collagen was determined by ELISA technique. RT-qPCR was used to verify the mRNA level of decorin and TGF- β_1. Results The mean concentration of type Ⅰ collagen in the premenopausal women in POP group [(47.94 ± 6.82) mg/g total protein (TP)]was significantly lower than that in control group [(62.33±6.57) mg/g TP],in the postmenopausal women in POP group, it was (41.82±5.96) mg/g TP, significantly lower than that in control group[(61.21 ± 4.84)mg/g TP](P< 0.01). The mRNA expression of decorin was 1.61 ± 0.10 in POP group, significantly lower than that in control group 2.77±0.60 ,while that of TGF-β_1 was higher in POP greup10.86 ± 0.23 than that in control group 9.87 ± 0.92 (P < 0.05). In the postmenopausal women in two groups, there were no significant difference in the mRNA expression of decorin and TGF-β_1 (P > 0.05). Conclusions A decrease in quantity of type Ⅰ coUagen in the connective tissue of anterior vagina may compromise the tensile strength and an increase susceptibihty to prolapse. Deeorin might be involved in the pathogenesis in premenopausal women with POP. The pathogenesis of POP is muhifactorial.

Objective To investigate the risk factors of hemorrhagic transformation (HT) after cerebral infarction. Methods The clinical and neuroimaging data of 100 patients (gender,age-matched)with cerebral infarction and hemorrhagic transformation from January 2005 to January 2010 were analyzed retrospectively. The following factors were listed for single factor analysis: the history of hypertension, diabetes mellitus,admission blood pressure,blood sugar,infarction size,alcohol,smoking,atrial fibrillation,hypercholesterolemia, combined anticoagulant and antiplatelet aggregation therapy. All the above factors were analyzed by chi-square test or t test, and Logistic regression analysis was used to screen out the related risk factors of HT from the potentially related factors. Results Atrial fibrillation (OR =5.483,95%CI:fibrillation,extensive cerebral infarction,blood sugar,high blood pressure at the beginning of the disease,combined anticoagulant and antiplatelet aggregation therapy are the major risk factors of HT. At the same time, the occurrence of HT is the result of the joint effect of multiple factors and multiple mechanisms.

Objective To evaluate the effect and safety of a modified Prolift procedure, without preceding partial trachelectomy or hysterectomy for pelvic organ prolapse (POP) with coexistent cervical elongation. Methods Clinical data of 72 patients that underwent a modified Prolift procedure for POP with coexistent cervical elongation, between December 2008 and June 2012 in Fuzhou General Hospital of Nanjing Military Command was retrospectively analysed. A comparison was carried out between preoperative and postoperative parameters of pelvic organ prolapse quantitation system (POP-Q), and an objective evaluation was made according to the overall cure rate and recurrence rate. Pelvic floor distress inventory-short form 20 (PFDI-20) was used to investigate the subjective cure rate and improvement of symptoms. Results Patients were followed up at median 52 months (36-78 months). One bladder perforation and one rectum perforation occurred during the procedure. Four patients (6%, 4/72) had uterine prolapse at 9-19 months after the opertaion and had transvaginal hysterectomy laterly. The overall anatomical correction rate was 94%(68/72). Six patients (8%, 6/72) had mesh exposures at 3-9 months after the opertaion. Scores of PFDI-20 decreased sifnificantly after the procedure (118.2±25.2 vs 12.1±8.0 vs 12.5±9.5 vs 13.0±9.9, P<0.05). The patients′ satisfaction rate was 92% (66/72). Conclusion This modified Prolift procedure, without preceding partial trachelectomy or hysterectomy, could effectively and safely correct POP with coexistent cervical elongation.

BACKGROUND:Currently, bone marrow mesenchymal stem cel s can differentiate into nerve cel s via many approaches. Different methods for inducing bone marrow mesenchymal stem cel s differentiating into nerve cel s have different ratios. OBJECTIVE:To investigate the difference between chemical method and co-culture method to induce the differentiation of rat bone marrow mesenchymal stem cel s into nerve cel s. METHODS:Rat bone marrow mesenchymal stem cel s were isolated and purified using whole bone marrow culture method, and then randomly divided into two groups:chemical group,β-mercaptoethanol was added;co-culture group, co-cultured in a Transwel chamber. RESULTS AND CONCLUSION:Visible protrusions from induced cel s showed radiation growth at 1 week of induced culture, and neuron-specific enolase staining was positive at 2 weeks of culture. Star-like structure of nerve cel s was visible in the co-culture group within 4-5 days of culture, and then more protrusions formed. Meanwhile, the positive rate of neuron-specific enolase was (70.82±2.46)%. After 6-7 days of culture, neuron-like cel s formed and were interconnected in the chemical group;while, the positive rate of neuron-specific enolase was (52.37±1.83)%. These findings suggest that cel microenvironment plays a leading role in the differentiation of bone marrow mesenchymal stem cel s into nerve cel s, and chemical induction method is inferior to the co-culture method.
