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 investigate the expression of LOXL2 protein (lysyl oxidase like-2 protein) and epithelial-mesenchymal transition (EMT) related markers in cholangiocarcinoma tissues and its relation with the malignant features. Methods The expression of LOXL2、E-cadherin and Vimentin protein in 48 cases of cholangiocarcinoma tissues was detected by immunohistochemistry and compared with the clinicopathological data of cholangiocarcinoma. Results The positive expression rate in cholangiocarcinoma was 71% ( 34/48 ) for LOXL2 and 46% ( 22/48 ) for Vimentin, the absent expression rate was 52% (25/48) for E-cadherin. The positive expression rate of LOXL2 was significantly associated with the absent expression of epithelium markers E-cadherin ( r = 0. 394, P < 0. 05 ) and the positive expression of fibroblast markers Vimentin ( r = 0. 406, P < 0. 05 ). There was no correlation between the expression of LOXL2 and patients gender, age, and cancer differentiation, but a significant correlation with tumor metastasis was found ( P < 0. 05 ). Conclusions LOXL2 protein overexpression in cholangiocarcinoma may accelerate invasion of cholangiocarcinoma through induced EMT.

Objective To investigate the correlation of the expression of KAI1/CD82 and laminin receptor (LNR) in cholangiocarcinoma, and study its role in the invasion and metastasis of cholangiocarcinoma. Methods The expressions of KAI1/CD82 and LNR in 48 cholangiocarcinoma tissue samples were detected by SP immunohistochemistry, and their relationships with clinicopathological factors were analyzed. Results The positive expression rates of KAI1/CD82 and LNR in cholangiocarcinoma were 31% (15/48) and 54% (26/48), respectively. In highly differentiated cholangiocarcinoma, the positive expression rate of KAI1/CD82 was high (χ2=3.911, P<0.05), while that of the LNR was low (χ2=6.970, P<0.05). The positive expression rate of KAI1/CD82 in cholangiocarcinoma with metastasis was significantly lower than that in cholangiocarcinoma without metastasis (χ2=5.765, P<0.05), while the positive expression rate of LNR in cholangiocarcinoma with metastasis was significantly higher than that in cholangiocarcinoma without metastasis (χ2= 9.952, P<0.05). The expression level of KAI1/CD82 was negatively correlated with that of the LNR ( r = -0.462, P < 0.01 ). Conclusions The up-regulated expression of LNR in cholangiocarcinoma correlates with the decreased expression of KAI1/CD82, and plays an important role in the invasion and metastasis of cholangio-carcinoma.

Objective To explore the surgical management of chronic pancreatitis complicated with pancreatolithiasis (CPPL). Methods The clinical data of 66 patients with CPPL were retrospectively analyzed. Pancreatolithiasis was classified into 4 types according to the location of stones: stones located in the head of the pancreas (type Ⅰ, n=28), stones located in the body of the pancreas (type Ⅱ, n=30), stones located in the tail of the pancreas (type Ⅲ, n=1) and stones located from the head to tail of the main duct of pancreas (type Ⅳ, n=7). Ten patients (including 4 with type Ⅰpancreatolithiasis, 5 with type Ⅱ and 1 with type Ⅳ) received conservative treatment; 10 patients with type Ⅰ pancreatolithiasis underwent lithotomy under endoscope; pancreaticoduodenectomy and Beger procedure were carried out on 14 patients with type Ⅰ pancreatolithiasis, pancreatolithotomy+pancreaticojejunostomy on 25 patients with type Ⅱ pancreatolithiasis, resection of pancreatic tail and spleen on 1 patient with type Ⅲ pancreatolithiasis, and Puestow-Gillesby procedure, dividing of the neck of pancreas+removing stones from both ends of pancreatic duct+Roux-en-Y pancreatojejunostomy on 6 patients with type Ⅳ pancreatolithiasis. Results Sixty-two patients were followed up for 2 months to 15 years, and the number of patients with recurrence for type Ⅰ, Ⅱ, Ⅲ and Ⅳ pancreatolithiasis was 4, 2, 0 and 3, respectively. Conclusions Early surgical management according to the location of stones should be carried out after confirmed diagnosis of CPPL. Individualized management based on correct diagnosis and classification plays an important role in the prevention of pancreatolithiasis recurrence.
