Objective To explore the diagnosis and treatment of pancreatic duct stones. MethodsClinical data of 29 cases of pancreatic duct stones were analyzed retrospectively. ResultsChronic pancreatitis was complicated in 21 cases, cholelithiasis in 12, pancreatic cancer in 2 . The correct diagnosis rate of ultrosonography, CT, ERCP and MRCP was 89.7%(26/29), 65.0%( 13/20 ),100%(6/6) and 100%(4/4) respectively. Six cases underwent EST,16 cases did transpancreatic duct lithotomy plus Roux-en-Y pancreaticojejunostomy, Three cases did sphincteroplasty, pancreaticoduodenectomy and exploratory laparotomy were performed in one each. ConclusionsChronic panreatitis cholelithiasis is the main causes of pancreatic duct stones. Imaging examinations help to make diagnosis preoperatively. Transpancreatic duct lithotomy plus Roux-en-Y pancreaticojejunostomy is the therapy of choices for patients with pancreatic duct stones.

Objective To investigate the expressions of Livin protein and VEGF protein in bladder urothelial carcinoma(BUC) ,and theirs relationships with the clinicopathologic parameters of bladder urothelial carcinoma. Methods The expression of Livin and VEGF protein in 69 samples of BUC tissue and 10 samples of normal bladder epithelium tissue were detected by immunohistochemical SP method. Their relationships with clinicopathologic data were statistically analyzed. Results The positive expression rate of Livin and VEGF in BUC tissues were 65.2% (45/69) and 46.4% ( 32/69), but negative in normal bladder epithelium tissues, which showed significant differences in the comparison (Ps ＜ 0. 05 ). We found significant difference in the comparison of Livin positive rate between groups with or without recurrence ( 78. 8 % vs 48. 1%, χ2 = 6. 13, P ＜ 0. 05 ); but no differences in pathological grade,TNM stage and tumor number( Gl 55.6% ,G2 64. 3% ,G3 73.9% ;Ta ～ T1 61.9% ,T2 ～ T4 70. 4%; Single-tumor 59. 6%, multi-tumor 77.3%; χ2 = 1.52,0. 52,2.07, Ps ＞ 0. 05 ). For BUC,the expression of VEGF was correlated with the pathological grade,TNM stage( Gl 16. 7% ,G2 53.6% ,G3 60. 9%, χ2 = 8. 91; Ta ～ T1 33.3%, T2 ～ T4 66. 7%; χ2 = 7. 34; Ps ＜ 0. 05 ), but not the tumor number and recurrence( Single-tumor 57.4% , multi-tumor 59. 1%, χ2 = 0. 01; with recurrence 51.5% , without recurrence 40. 7% ,χ2= 0. 69; Ps ＞ 0. 05 ). We found no relationship between the expression of Livin and VEGF (r =0. 056,P ＞ 0. 05 ). Conclusion The overexpressions of Livin and VEGF protein may play an important role in the occurrence and development of BUC. Combind detection of these two protein can be used in the diagnosis and prognosis of BUC.

Mycobacterium abscessus infection is a rare and serious complication of prosthetic breast augmentation. In March 2020, Foshan Huamei Plastic Surgery Hospital treated a 35-year-old female patient with Mycobacterium abscessus infection after breast augmentation mammoplasty. Twenty days post surgery, there was pain and swelling onthe whole left breast, especially the incision, and the main clinical symptoms such asobvious fluctuation, obvious tenderness andhighskin temperature. Then the left breast implant was removed, and bacterial culture and susceptibility testing of the secretions in the operation area were performed. According to susceptibility testing result, antibiotics were used intravenouslyand the cavity of the operation area was flushed. After 9 months flushed treatment, the infection was controlled and followed up for 14 months. There was norecurrence on the left breast. In the whole treatment, it is necessary to ensure the continuity of the treatment, especially the early stage of the infection, in order to ensure the possibility of cure of the disease.
