Objective To study the efficacy and security of solifenacin in prevention of cystospasm after radical prostatectomy. Methods The clinical data of 93 localized prostate cancer patients who had underwent laparoscopic radical prostatectomy were retrospectively analyzed. The patients were divided into solifenacin group (52 cases) and control group (41 cases) based on the condition of taking solifenacin after operation. The day and night frequency and duration of cystospasm from the first day to the third day after operation, incidence of urine extravasation, duration of bloody urine, time of pelvic cavity drainage and ureter retention, untoward reaction (dry mouth, headache and abdominal distention) was compared between two groups. Results The day and night frequency and duration of cystospasm at second day and third day after operation in solifenacin group were significantly lower than those in control group. Day frequency of cystospasm: (1.54 ± 0.42) times vs. (3.35 ± 0.43) times and (1.38 ± 0.58) times vs. (2.86 ± 0.66) times, night frequency of cystospasm:(1.66 ± 0.63) times vs. (3.58 ± 0.72) times and (1.47 ± 0.33) times vs. (3.27 ± 0.68) times, duration of cystospasm:(0.18 ± 0.11) h vs. (0.33 ± 0.18) h and (0.21 ± 0.09) h vs. (0.29 ± 0.21) h, and the incidence of urine extravasation at the third day after operation in solifenacin group was significantly lower than that in control group: 1.92% (1/52) vs. 17.07% (7/41), and there were statistical differences (P<0.05). The duration of bloody urine, time of pelvic cavity drainage and ureter retention after operation in solifenacin group were significantly shorter than those in control group:(30.2 ± 5.6) h vs. (48.3 ± 4.7) h, (50.6 ± 5.9) h vs. (70.3 ± 6.2) h and (7.6 ± 1.4) d vs. (10.4 ± 0.9) d, and there were statistical differences (P<0.05). There was no statistical difference in untoward reaction between 2 groups (P>0.05). Conclusions Solifenacin can reduce the frequency of cystospasm and shorten the duration of cystospasm effectively after radical prostatectomy. It has a positive effect on reducing the incidence of urinary extravasation and shorting the extubation time. It is helpful to improve the quality of life and the recovery of the patients.

Objective To compare the effect of different urethrovesical anastomosis methods on postoperative anastomotic complication in laparoscopic radical prostatectomy (LRP). Methods The clinical method of 121 patients with localized prostate cancer who underwent LRP from June 2012 to June 2015 was retrospectively analyzed.

The multipotent differentiation and immunosuppression capability of mesenchymal stem cells (MSCs) make it attractive source for stem cell therapy to treat serious diseases, including neural system diseases and immune disorders. For large scale clinical applications, MSCs have to be expanded to produce sufficient quantity for multiple treatments. While conventional passaging is not appropriate for such a task, bioreactor can be used to expand MSCs more efficiently. Yet the efficacy and biosafety of expanded MSCs must be properly assessed before the expanded MSCs can be implanted. This review presented state-of-the-art in expanding MSCs focusing on the progress on the assessment of the efficacy and biosafety of in vitro expanded MSCs. Current obstacles were discussed and future research directions were outlined.

Objective:To investigate the expression of coxsackievirus-adenovirus receptor (CAR) in thymic carcinoma and the relationship between CAR and the antitumor activity of oncolytic adenovirus H101.Methods:The expression of CAR in thymic carcinoma tissues and cells were detected by RT-qPCR and Western blot. H101 expression and virus titers in Bcap-37, MP59 and T1889 cells after infection were detected by RT-qPCR and 50% tissue culture infectious dose (TCID 50). The proliferation activity and apoptosis rates of T1889 cells infected with H101 at different multiplicity of infection (MOI) were detected by CCK-8 and flow cytometry. CAR expression in T1889 cells treated with different concentrations of trichostatin A (TSA), a histone deacetylase inhibitor, was detected. H101 expression and virus titers in the TSA-treated and H101-infected cells were detected. Cell activity was detected by CCK-8. The phosphorylation levels of MARK and ERK1/2 and the expression of CAR at protein level in TSA-treated or TSA+ TBHQ (ERK activator) treated cells were detected. Results:CAR expression at both mRNA and protein levels were significantly lower in thymic carcinoma tissues than in adjacent normal tissues ( P<0.01), and lower in MP59 and T1889 cells than in thymic epithelial cells (TEC) and Bcap-37 cells ( P<0.01). H101 expression in MP59 and T1889 cells and the titers of H101 in culture supernatants were significantly lower than those in Bcap-37 cells ( P<0.01). Compared with Bcap-37 cell, the activity of MP59 and T1889 cells was significantly increased and the apoptosis rates were significantly decreased 48 h after H101 infection ( P<0.01). The expression of CAR at both mRNA and protein levels in T1889 cells treated with different concentrations of TSA increased in a dose-dependent manner. When T1889 cells were treated with 0.25 μmol/L of TSA, the expression of H101 at mRNA level and H101 titers were significantly increased ( P<0.05); the phosphorylation levels of MAPK and ERK1/2 proteins were continuously decreased; the expression of CAR was continuously increased. Compared with the TSA treatment group, the expression of CAR at protein level in the TSA+ TBHQ treatment group decreased significantly ( P<0.01), and the p-ERK1/2/ERK1/2 ratio increased significantly ( P<0.01). Conclusions:TSA could up-regulate CAR expression in thymic carcinoma by inhibiting the MARK/ERK1/2 pathway, thereby enhancing the antitumor activity of H101.
