RESUMEN
Objective:To evaluate the safety and long-term effectiveness of endoscopic foam sclerotherapy (FS) combined with endoscopic rubber band ligation (ERBL)in the treatment of grade Ⅱ-Ⅲ internal hemorrhoids.Methods:Consecutive patients diagnosed as having grade Ⅱ-Ⅲ internal hemorrhoids in Xinhua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January to December 2020 were prospectively enrolled in the study, and randomly divided into ERBL group and FS combined with ERBL group. The 24 h visual analogue scale (VAS) for pain and 1-week degree of bleeding were evaluated after the treatment. After follow-up of 6 months, the effectiveness of treatment was evaluated.Results:A total of 84 patients with age of 54.4±7.9 years were enrolled, 57.1% (48/84) males, and 73.8% (62/84)grade Ⅱ internal hemorrhoids. Forty-three patients were assigned to the ERBL group and 41 to the FS combined with ERBL group. There was no significant difference between the two groups in baseline data ( P>0.05). In the FS combined with ERBL group, the mean amount of polidocanol foam was 13.8±2.5 mL, the mean number of injection site was 4.7±1.2, and the median scores of VAS was 0 (0, 3), which was significantly lower than that of ERBL group [2 (0, 4), Z=-2.116, P=0.034]. The bleeding rate 1 week after treatment in the ERBL and FS combined with ERBL group were 20.9% (9/43) and 29.3% (12/41), respectively, and mild bleeding was the main symptom. There was no significant difference between the two groups in the bleeding degree ( U=807.0, P=0.378). After 6 months of follow-up, the total effective rates in the ERBL group and the FS combined with ERBL group were 81.4% (35/43) and 90.2% (37/41), respectively ( U=684.5, P=0.044). Conclusion:FS combined with ERBL can effectively relieve post-treatment perianal pain, and improve the long-term effectiveness.

RESUMEN
Objective@#To investigate the feasibility and effectiveness of endoscopicretrograde cholangio-pancreatography(ERCP)in the management of long-term complications after pancreaticoduodenectomy.@*Methods@#From January 2009 to July 2018, the clinical data of 62 patients with biliary or pancreatic long-term complications after pancreatoduodenectomy were reviewed at Department of General Surgery, and the corresponding ERCP were carried out in the multi-disciplinary cooperation.There were 39 males and 24 females.The age was 56.5 years(aging from 13 to 76 years). The time of treatment was 3 months to 20 years after pancreatoduodenectomy.The long-term biliopancreatic complications after pancreatoduodenectomy included 51 cases of biliary calculi, 42 cases of bilioenteric anastomotic stenosis with proximal bile duct dilatation, and 11 cases of pancreaticointestinal anastomosis stenosis with distal pancreatic duct dilatation.All patients received conventional duodenoscopy or single-balloon enteroscopy assisted ERCP under general anesthesia.@*Results@#A total of 95 ERCP were performed in 62 patients, averaging 1.5 times per case.The long-term complications of cholangiopancreatic after pancreatoduodenectomy(ERCP indications) included 56 times of bile duct stones(58.9%), 45 times of bilioenteric anastomatic stricture(47.4%), 11 times of recurrent pancreatitis(11.6%), 6 cases(6.3%) of bilioenteric anastomatic foreign body, 3 times of intrahepatic bile duct stenosis(3.2%). Among the 95 times, 82 times(86.3%) achieved endoscopic endoscopy, 76 times(80.0%) were diagnosed successfully, and 72 times(75.8%) were successfully treated with ERCP.Small intestinal perforation occurred in 1 patient undergoing duodenoscopy, and then healed by surgical repair.@*Conclusion@#Multi-disciplinary collaboration of ERCP is safe and effective in the treatment of long-term complications after pancreaticoduodenectomy, but the long-term effect still needs further clinical follow-up.
RESUMEN
Background: The incidence of inflammatory bowel disease (IBD) is increasing in recent years, and the etiology and pathogenesis of IBD remain unclear.Studies showed that disorder of bile acid metabolism plays an important role in the pathological process of experimental colitis.However, serum bile acid profile in IBD patients has not been reported.Aims: To investigate the changes of serum bile acid profile in patients with IBD.Methods: Seven healthy controls, 15 patients with ulcerative colitis (UC) and 16 patients with Crohn's disease (CD) at Shanghai Xin Hua Hospital were enrolled.High-performance liquid chromatography-mass spectrometry was used to determine serum bile acid profile.Results: No significant differences in serum concentrations of primary bile acid cholic acid (CA), chenodeoxycholic acid (CDCA), glycocholic acid (GCA), taurocholic acid (TCA), glycochenodeoxycholic acid (GCDCA) were found between UC or CD and controls (P>0.05).Compared with controls, serum concentration of secondary bile acid deoxycholic acid (DCA) in UC patients was significantly decreased (P<0.05), glycodeoxycholic acid (GDCA), taurodeoxycholic acid (TDCA) in CD patients were significantly decreased (P<0.05), serum concentration of lithocholic acid (LCA) in UC and CD patients was significantly decreased (P<0.05).Conclusions: The serum bile acid profile in IBD patients is significantly changed, which suggests that it may be involved in the pathological process of IBD.
RESUMEN
Objective To investigate the anti carcinoma role of integrin targeted photodynamic therapy (PDT) on pancreatic carcinoma cells in vitro.Methods Pancreatic carcinoma cells SW1990 were divided into four groups:cells without quantum dots (QDs) and light-treated as blank control group,pure light-treated group,photosensitizer group and PDT group.The targeting of QDs-arginine,glycine,aspartic acid (RGD) and integrin probe was confirmed by laser confocal microscopy.And as a photosensitizer for photodynamic therapy,after treated for 48 hours the morphology changes of pancreatic carcinoma cells of each group were observed.After 48 hours,the cell proliferation,apoptosis and cell cycle changes were detected by methyl thiazolyl tetrazolium (MTT) assay and flow cytometry (FCM).The expressions of myeloid cell leukemia-1 (Mcl-1),protein kinase B(Akt) and tumor necrosis factor-related apoptosis inducing ligand (TRAIL) were detected by reverse transcriptase polymerase chain reaction(RT-PCR).The amount of reactive oxygen species (ROS) of each group were evaluated by fluorescence probe.One-way ANOVA was performed for comparison between groups to analyze the treatment effects of PDT group.Results The QDs RGD probe could effectively targeting pancreatic carcinoma cells.The MTT results indicated that the relative inhibition rate of pancreatic carcinoma cells proliferation of PDT group was statistically higher than that of the other groups at 24,48,72 h (F=73.00,85.10,126.58; all P＜0.01).The FCM results revealed that the cell apoptosis rate of PDT group (17.860％ ±1.230％) was higher than that of the other groups (F=130.617,P＜0.01) and cell cycle G0/G1 phase (69.14％±2.63％) and S phase (24.41％ ± 2.67 ％) retardance was also significant (all P＜0.05).The expression of proliferation and apoptosis related gene Mcl-1 and Akt at mRNA level was lower than that of the other groups however the expression of apoptosis-inducing ligand TRAIL at mRNA level was higher than that of the other groups (F=567.456,446.817,145.238; all P＜0.05).The ROS level of PDT group was higher than that of the other groups (F=3262.559,P＜0.01).Conclusion PDT with a QDs-RGD probe could significantly inhibit pancreatic carcinoma cell proliferation and promote cell apoptosis.
