Objective To compare the use of solifenacin and trospium in treatment of overactive bladder (OAB).Methods This prospective study was conducted on patients diagnosed with OAB who presenting to the Department of urology,Changzhou No.3 People's Hospital between March 2015 and May 2016.Patients were randomized into 2 groups.Group A (n =40) received 5 mg solifenacin once daily,while Group B (n =39) received 20 mg trospium twice daily.All the patients' OAB symptom scores (OABSS) in weeks 0,4,and 12 were recorded.In addition,side effects of the drugs were evaluated.Results Average OABSS was determined as:9.3 ± 2.6 (Group A) and 10.2±1.9 (Group B) at week0;2.5±1.3 (GroupA) and 2.7±1.4 (Group B) at week4;and 1.4±0.5 (Group A) and 1.3 ± 0.6 (Group B) at week 12.In addition,no statistically significant difference was found between the scores (P =0.084,P =0.512 and P =0.423).The discontinuation rate of medication due to its side effects was 0 (0%) for Group A,and 5 (12.8%) for Group B.Intragroup changes in the scores 0 weeks-4 weeks,0 weeks-12 weeks and 4 weeks-12 weeks values was statistically significant in both groups (P =0.000).Conclusion No significant difference was found between the OABSS of these 2 drugs.However,discontinuation of drugs due to side effects was more frequent in trospium.

Objective To investigate the clinical effects and safety of spiral stone basket assisted with FURL in the treatment of unilateral upper ureteral stones for diameter>1.0 cm. Methods 140 patients with unilateral upper ureteral stones for diameter>1.0 cm from January 2012 to December 2015 were randomly divided into control group (70 patients) with FURL used alone and observation group (70 patients) with spiral stone basket assisted application on the basis of control group;the perioperative clinical indicators, the lithotripsy success rate, the stone clearance rate, the stone removal rate and the postoperative complication incidence of both groups were compared. Results The operation time of observation group was signiifcantly longer than control group (P0.05). The lithotripsy success rate and the stone clearance rate of observation group was signiifcantly higher than control group (P 0.05). The total treatment expenses of observation group was signiifcantly fewer than control group (P1.0 cm can efifciently higher the stone removal effects, reduce the stone removal risk and not increase the postoperative complications incidence.

Objective To compare the biological characteristics of adipose-derived mesenchymal stem cells (ADAS) and bone marrow derived mesenchymal stem cells (BMSCs).Methods The adipose and bone marrow-derived sources of mesenchymal stem cells were separated,and their phenotype,cell doubling time and the secretion of factors were compared.They were also used to detect T-cell cycle,activation,and proliferation inhibition.Results BMSCs and ADAS were similar on the cell phenotype and the differences only existed in the expression of only CD106.For the proliferation rate,ADAS grew faster than BMSCs (doubling time 28 h vs.39 h,P<0.05); ADAS and BMSCs also had the same ability to inhibit T cell proliferation,and dose-dependent effects existed in mitogen-stimulated Tcell proliferation and MLR: there was a strong inhibitory effect in 1:2,but this effect disappeared at 1: 100.Both ADAS and BMSCs could arrest most T cells in the G0/G1 phase,but the role of ADAS was weaker than that of the BMSCs.ADAS could not inhibit apoptosis of T cells.ADAS and BMSCs played the same roles in inhibiting the differentiation of TH0 to TH1 or TH2: mainly inhibiting differentiation of TH 0 to TH1 cells (IL-2-and IFN-γ-producing cells),but having no significant effect on TH2 cells (IL-4-and IL 10-producing cells).Conclusion ADAS and BMSC have a similar role in immune regulation.In the same volume,fat tissue has the number of more than 10 times of stem cell precursor cells than that of bone marrow,so adipose tissue is a more promising stem cells transplant source.

Objective To investigate that whether the immuno-modulatory capacity is intact in myelodysplastic syndrome-refractory anemia (MDS-RA) derived mesenchymal stem cell (MSCs) and what are the differences compare with those from normal donors.Methods Isolating MSC from MDS and normal donors respectively and exam their differences on T lymphocyte activation,proliferation and suppression.Results The results showed that the capacity of suppressing T cell proliferation and activation is weakened.Conclusion We propose that MSCs from pathological environment might be abnormal and should not be used for autologous transplantation.

AIM:To observe the postoperative effect of the application of expanded artery island skin flap on the treatment of injuries of face.METHODS:Totally 20 patients,who were treated with expanded artery island flap transplantation for face injury at Cosmetic and Plastic Institute,Weifang Medical College,were selected between January 1997 and September 2004.Patients knew the trial and agreed to participate in it.All patients received two phases operation:During the first period of the treatment,according to the different characteristics and requirements of the patients,suitable expander was implanted and water was input regularly.During the second period,the expanded island skin flap was used to cure the injuries on the face or do organ reconstruction.The skin flap was 2.5 cm? 3.5 cm-5.0 cm?7.5 cm,and vessel pedicle was 12.5 cm at most.Follow up was done regularly after operation.RESULTS:A total of 20 patients were involved in the result analysis,no drop out.Follow-up was done for 6-24 months in 20 patients.There were 4 cases of at least 6 months and less than 12 months,7 cases of at least 12 months and less than 18 months,9 cases of at least 18 months and less than 24 months.After expandor implantation in the first period,the expanded skin received skin repair or organ reconstruction in the second period.The healing of the injuries was good and scars of the skin and organ displacement were not clearly seen.Their function was recovered well and shape was ameliorated.CONCLUSION:The expanded island skin flap can provide comparatively large-region flap and long vessel pedicle to increase the angle and flexibility of flap rotation,and make the repair looks closer to the normal area.

BACKGROUND: The mostly accepted standpoints regarding adult stem cell plasticity are that adult stem cells existing in various organs contain primitive pluripotent stem cells. However, the origin, identification methods and biological characteristics of pluripotent stem cells remain unclear. OBJECTIVE: To investigate if a kind of pluripotent stem cells with more primitive character can be isolated from adult tissues. DESIGN, TIME AND SETTING: The in vitro cytology observation was performed at the Center of Tissue Engineering, Basic Medical Department of Peking Union Medical College from March 2007 to January 2008. MATERIALS: Pregnant BALB/C rats on gestation day of 12.5-14.5 d were adopt in the study. METHODS: The fetal perisome samples were attained from pregnant BALB/C rats under sterile conditions, and made into cell suspension by trypsin digestion method. Immunomagnetic beads were used to sort Sca-1+CD117-Lin-cells. When 70%-80% cells were mixed, the cells were subcultured, and the 5 passage cells were taken in the experiment. MAIN OUTCOME MEASURES: Microstructure, ultrastructure, growth characteristics, immunophenotype and embryonic stem cell associated antigen were analyzed by inverted phase contrast microscope, scanning electron microscope, flow cytometry and RT-PCR respectively. Histochemical and immunofluorescence staining were used to investigate the potentiality of the Sca-1+CD117-Lin-cells differentiated into trilaminar germ disc. RESULTS: Sca-1+CD117-Lin-cells adhering to the wall with spindle or short fusiform shapes, which could amplification fast and stablely to 50 passages. Cells were found logarithmic growth on days 3-7, after that cell growth reached platform stage. There were about 32 h for doubling time, 90.43% cells were at the G0/G1 phase, and 9.57% at the G2/M+S phase. The cells expressed high levels of Sca-1, no levels of CD117, CD14, CD19, CD31, CD34, CD45 and Flk-1, and moderate levels of CD44. The phenotype of human BMSCs was stabilization. Embryonic stem cell associated antigen Sox2, Oct-4 or Nanog were showed positive expression. RT-PCR indicated that the cells were able to differentiate into osteoblasts, adipocytes, chondrocyte, hepatocyte-like cells and neuroglia cells in vitro. CONCLUSION: The Sca-1+CD117-Lin-cells isolated from adult tissue are primitive multiple potential adult stem cells, which can differentiate into trilaminar germ disc.
