ABSTRACT
Type Ⅰ congenital biliary dilatation is a congenital biliary duct defect disease.It is also called congenital choledochocele cyst (CCC).Endoscopic ultrasonography (EUS),magnetic resonance cholangiopacreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) are very important for the diagnosis.Operation is generally regaded as the best choose.It is recommended that cholecystectomy + choledochal cyst excision + hepatic duct jejunum Roux-Y anastomosis is the chief therapeutic method.This article reviews the pathogenesis,classifications,diagnosis and treatment of the disease.
ABSTRACT
Objective To investigate the related factors affecting prognosis of patients with colorectal cancer undergoing palliative resection.Methods The clinical data of 345 patients with colorectal cancer who underwent palliative resection at the First Affiliated Hospital of Guangxi Medical University between January 2007 and December 2011 were retrospectively analyzed.Patients selected the emergent operations or restrictive operation based on the conditions of patients,and then received chemotherapy,radiotherapy and biotherapy.Chemotherapy regimens included FOLFOX4 (5-FU/CF + oxaliplatin) regimen,XELOX (capecitabine + oxaliplatin) regimen and FOLFIRI (5-FU + CF + irinotecan) regimen.Biotherapy regimens included molecular targeted therapies using bevacizumab and cetuximab.The follow-up was applied to patients by outpatient examination,telephone interview and correspondence once every 3 months up to March 1,2014.The survival curve was drawn by the Kaplan-Meier method.The survival rate was analyzed using the Log rank test.The multivariate analysis was done using the COX regression model.Results Of the 1 930 patients,345 patients received palliative resection with a percentage rate of 17.876％.Among the 345 patients,104 patients received emergent operations and others received restrictive operations.After operation,178 patients received adjuvant treatment,FOLFOX4 regimens were done on 85 patients,XELOX regimens on 32 patients,FOLFIRI regimens on 20 patients,radiotherapy on 17 patients and molecular targeted therapies on 24 patients.Seven patients died in the perioperative period and other patients were followed up for 3.0-82.0 months with a median time of 14.0 months.The 1-,3-and 5-year survival rates and the mean survival time were 49.57％,11.88％,6.38％ and 22.6 months,respectively.The results of univariate analysis showed that the CEA levels,bowel obstruction,primary tumor resection,peritoneal implantation,distal metastasis,lymph node metastasis,tumor differentiation,postoperative adjuvant therapy were related factors affecting the prognosis of patients undergoing palliative resection (x2=3.742,18.795,37.641,13.470,4.228,5.835,4.108,6.875,P ＜0.05).The results of multivariate analysis showed that the bowel obstruction,without primary tumor resection,peritoneal implantation,low-differentiation of tumor and without postoperative adjuvant therapy were the independent risk factors affecting the prognosis of patients undergoing palliative resection (RR =1.674,2.273,1.947,1.582,1.342,95％ confidence interval:1.193-2.485,1.646-4.376,1.497-3.587,1.184-2.382,1.032-2.074,P ＜ 0.05).Conclusion The low-differentiation of tumor,peritoneal implantation,bowel obstruction,without primary tumor resection and without postoperative adjuvant therapy are the independent risk factors affecting the prognosis of patients with colorectal cancer undergoing palliative resection.
ABSTRACT
Objective: To investigate the effect of Trichostatin A (TSA) on histone acetylation and expression of ING1b mRNA in Colo205 human colon cancer cell line. Methods: Human colon cancer Colo205 cells were cultured and divided into 4 groups. Cells in the control group (group A) was treated without TSA. In the other three groups, cells were treated with 3 different concentrations of TSA: 50μg/L (group B), 100μg/L (group C), and 200μg/L (group D). At 24 hours after treatment, the level of histone H3 acetylation was analyzed by chromatin immunoprecipitation (CHIP) and the expression of ING1b mRNA was detected by RT-PCR with qPCR. The growth of Colo205 human colon cancer cells in group C and D was obviously inhibited compared with that in group A and B. Results: The Ct value of histone H3 acetylation and mRNA expression of ING1b in group A were 23.25± 0.08 and 23.32±0.05, respectively. After treatment with TSA, the 2~(-△△Ct) value of histone H3 acetylation in group B, C, and D were 1.12, 4.21 and 4.38, respectively. The level of histone H3 acetylation in group C and D was increased more compared with that in group A (P<0.05) and there was no difference between group B and group A (P>0.05). The 2~(-△△Ct) value of the expression of ING1b mRNA in group B, C and D were 1.33, 4.52 and 4.62, respectively. The expression of ING1b mRNA in group C and D were more than that in group A (P<0.05). Group B and group A had a similar level of ING1b mRNA expression (P>0.05). Conclusion: The histone acetylation is probably responsible for ING1b expression silencing in Colo205 human colon cell line. TSA at 100μg/L can increase the level of acetylation and activate the gene transcription which is silenced by low level of acetylation and induce the expression of gene, inhibiting the growth of tumor cells.
ABSTRACT
Objective:To observe the therapeutic effect ofexternal application ofChinese herbal medicine film plus acupoint-injection on breast hyperplasia.Methods:The 120 cases ofbreast hyperplasia with syndrome ofthe liver failing to maintain the normal flow ofqi were randomly divided into treatment group(40cases) which was treated by external application ofChinese herbal medicine film plus acupoint-injection, acupoint-injection group(40 cases) and control group(40cases).The changes ofsymptoms and signs, level ofserum sexual hormone and color doppler ultrasound analysis ofthree group were observed for comparison.Results:After 1 course oftreatment, the total effective rate oftreatment group was obviously higher than that ofcontrol group(P0.05).After 2 courses oftreatment, the total effective rate oftreatment group and acupoint-injection group was obviously higher than that ofcontrol group(P
ABSTRACT
<p><b>OBJECTIVE</b>To point out and define "insertion obstacle" (IO) as another sort of sexual dysfunction.</p><p><b>METHODS</b>A retrospective review was done on 32 patients with IO. They were diagnosed by self-rating insertion scale(SIS) designed by reference to the first five questions in OLeary's "Brief Male Sexual Function Inventory for Urology" (1995), involving sexual desire and erection and insertion, and treated mainly by psychological behavior therapy.</p><p><b>RESULTS</b>Of the 32 cases, 30 patients were diagnosed as IO, 29 (90.6%) were simple psychological IO, and successfully cured by psychological behavior therapy.</p><p><b>CONCLUSIONS</b>IO, as a sort of sexual dysfunction, could be diagnosed by SIS, and cured by psychological behavior therapy.</p>
