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.

Objective To study effects and other related problems of surgery for patients with cervical spine fracture and ankylosing spondylitis.Methods Twelve patients with cervical spine fracture and ankylosing spondylitis were treated with surgery from April 1986 to April 2004.All eases were studied retrospectively.They were followed up for an average of 67.5 months and their complete clinical data were kept.The neurological function was evaluated by ASIA (American Spinal Injury Association) impairment scale,and the image analyzing software (Image-Pro Plus 5.1) was used to measure the angles of superior and inferior vertebral bodies of the fusion segment at flexion and extension positions.The difference between flexion and extension angles,?,served as the parameter of interspinal movement.According to the definition of spinal fusion by FDA (Food and Drug Administration),the?≥4?was considered as nonfusion.Other related problems were discussed by descriptive study.Results The average improvement in the nine patients with neurological injury was 1.3 ASIA grades.The injured segments in 10 cases were treated with fusion,of whom nine were fused by internal fixation.The fusion rate was 100%.Three cases were scheduled to have laminoplasty,but two had to receive laminectomy instead because of intraoperative complete fracture at the hinged side.Ten patients were complicated by insufficient function of major organs preop- eratively,and endotracheal intubation was difficult to perform in eight cases.Postoperative complications occurred in three cases,but fortunately healed completely.There were no deaths or fatal complications.Conclusions The neurological function can be improved by surgery for patients with cervical spine fracture and ankylosing spondylitis. Although the cervical spine is instable for most of the patients,fusion with internal fixation is indicated and can be successful.Those who had preoperative systemic diseases are likely to suffer from postoperative complications.The difficult endotracheal intubation is a common intraoperative problem.

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.

Gastrointestinal bleeding is a common complication of gastrointestinal diseases and gastrointestinal surgery, which may lead to hemorrhagic shock or cause death if not treated properly and promptly.Currently, endoscopic treatment for gastrointestinal bleeding includes clip closure, endoscopical injection of saline/adrenaline, argon plasma coagulation (APC), electrocoagulation and heater probe coagulation etc..Endoscopic clip closure mainly includes traditional closure through-the-scope clip (TTSC) and more novel closure over-the-scope clip (OTSC).This article reviewed the use of OTSC in the treatment of gastrointestinal bleeding.

Objective To explore the clinical effect of two-points approach vascular stenting technique (via both the femoral artery and posterior tibial artery of the affected side) in repairing blunt popliteal artery injuries.Methods The clinical data of eleven patients with blunt popliteal arterial injuries,who were treated with two-points approach vascular stenting technique during the period from March 2011 to March 2015 as single-approach stenting repair failed,were retrospectively analyzed.First,antegrade puncture of the femoral artery on the affected side with subsequent angiography was performed to evaluate the arterial injury,when the attempt to push the guide-wire to pass the injured arterial segment by twisting manipulation failed the puncture of posterior tibial artery was immediately carried out,then,a 4-French single-bend catheter together with a goose neck snare was inserted.Guide-wire capture technique was used to gasp the guide-wire in the injured artery segment,and then the guide-wire was pulled to pass through the injured artery segment.In this way,the guide-wire working circle was reliably established,and along the guide-wire the vascular stent was inserted and delivered to the right site to repair the injured artery.A 6-French guiding catheter was inserted to perform thrombus aspiration for eliminating the distal outflow obstruction caused by thrombus.Thrombolytic therapy with small dose of urokinase through a indwelling catheter was employed for the treatment of peripheral arterial thrombosis.Results The technical success rate was 100％.Angiography revealed that partial transection of artery was detected in 7 patients,and complete transection of artery in 4 patients.A total of 16 stents were implanted.No perioperative mortality or procedure-related complication occurred.All patients were followed up for 13-24 months,with a mean of (18.7±3.8) months.In-stent thrombosis occurred in 2 patients,which was treated with thrombolytic therapy and the blood flow recovered;severe in-stent stenosis (＞70％) was seen in 3 patients,in whom the blood flow returned to normal after balloon dilation therapy;mild in-stent stenosis (＜30％) was found in 6 patients,and no special treatment was given.During the follow-up period,no stent fracture,deformation,or displacement was seen,and no patient needed to have an amputation surgery.Conclusion In treating blunt popliteal artery injuries,two-points approach vascular stenting technique can effectively reduce the operation time,rapidly recover the blood flow of the injured popliteal artery,and shorten the time of limb ischemia.This technique has very satisfactory clinical shortterm effect.

OBJECTIVE: To explore the pathogenic mechanism of liver-yang hyperactivity type of hypertension and to observe the effects of Pinggan Qianyang Formula (PGQYF), a compound of traditional Chinese herbals for calming the liver and suppressing yang, so as to provide experimental evidence for new marker proteins of drug therapy. METHODS: A rat model of liver-yang hyperactivity was prepared with spontaneous hypertensive rats (SHRs) by administration of Aconiti Praeparatae Decoction. Adrenal proteins were separated by 2D gel electrophoresis (2-DE). The differentially expressed proteins were identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) and database analysis. RESULTS: The rat model of liver-yang hyperactivity was successfully reproduced, and the PGQYF could decrease the grades of irritability, conjunctival congestion and systolic blood pressure of the rats (P<0.05, P<0.01). After analysis, twelve obviously differentially expressed proteins were found, eight of which were identified. The expression levels of isocitrate dehydrogenase and steroidogenic acute regulatory protein in the untreated group were up-regulated as compared with those in the normal control group, and down-regulated in the treatment group. The expression levels of ferritin light chain, elongation factor Tu, Rho GDP disassociation inhibitor 1, flavin reductase and basic transcription factor 3 in the untreated group were down-regulated as compared with those in the normal control group, and up-regulated in the treatment group. CONCLUSION: Differentially expressed adrenal proteins in SHRs with live-yang hyperactivity are successfully identified. This approach may lay a foundation for the further investigation of pathogenic mechanisms in hypertension with liver-yang hyperactivity and the mechanisms of PGQYF treatment.
