Objective To compare the efficacy of tramadol for patient-controlled intravenous versus provicial epidural analgesia (PCIA vs PCEA) and their effects on the T-lymphocyte subsets and natural killer (NK) cells during postoperative period in patients undergoing gynecological operation for tumor. Methods Thirty-nine ASA Ⅰ-Ⅱ patients aged 18-83 yr undergoing elective surgery for ovarian cancer or uterine cancer or myoma were randomly divided into two groups : PCIA group (n = 21) and PCEA group ( n = 18). Premedication consisted of intramuscular atropine 0.5 mg and phenobarbital 0.1 g. Operation was performed under epidural anesthesia. Epidural catheter was inserted at T12 -L1 approximately 3-4 cm into epidural space cephalad. The patients received a test dose of 2% lidocaine 5 ml. The first dose was 2% lidocaine 10-12 ml followed by 0.5% bupivacaine 5 ml every 45-60 min. Tramadol 100 mg was given iv in PCIA group or epidurally in PCEA group 15 min before the end of surgery. 100 ml of PCIA solution contained tramadol 800 mg (16 ml), haloperidol 5 mg (1 ml) and normal saline 83 ml and 100 ml of PCEA solution contained tramadol 400 mg (8 ml), haloperidol 5 mg (1 ml) and NS 91 ml. The PCA pump was set to deliver a background infusion at 2 ml?h-1 and a bolus dose 0.5 ml with lock-out interval of 15 min. Analgesia was assessed using VAS. Venous blood samples were taken for determination of T-lymphocyte subset (CD3+ , CD4+ , CD8+) and NK cell counts by flow cytometry the day before surgery and on 1st and 2nd postoperative day. Results The postoperative analgesia was satisfactory in both groups, and there was no significant difference in VAS scores between the two groups. No vomiting and respiratory depression were observed in both groups. The NK cell counts decreased significantly on the 1 st and 2nd postoperative day as compared with the preoperative value (P

Objective To evaluate Feridex(superparamagnetic iron oxide,SPIO)enhanced MRI in the diagnosis of hepatic lesions.Methods Feridex-enhanced MRI was performed in 31 patients with CT,or MRI proved or suspected hepatic lesions.T 2WI signal intensity of hepatic parenchyma,lesion and background noise was measured before and after enhancement separately.SNR and CNR of parenchyma and lesion before and after enhancement were calculated.The number of lesions on plain and enhanced scans were observed and alalyzed.Results Post-enhancement SNR of liver significantly decreased (?0.05).Post-enhancement lesion-liver CNR increased significantly (?

Objective To evaluate the value of endoscopic ultrasound (EUS) in differentiatied diagnosis for stromal tumour and lipoma in duodenal tract.MethodsThe EUS images of 44 cases of stromal tumour(30 cases) and lipoma( 14 cases) which were confirmed by pathological results were analyzed retrospectively.The location,size,layer of origin,margin,internal echo pattern and homogeniety of the lesion were recorded and compared.Results Compared with lipoma,stromal tumour showed a significant difference in the layer of origin,margin,internal echo and homogeniety ( P < 0.05 ),but there was no statistical difference in the lesion location and size( P >0.05).ConclusionsEUS is greatly helpful to the differential diagnosis of stromal tumour and lipoma in duodenal tract.

Objective To analyze the clinical pathological characteristics of achalasia patients complicated by esophageal cancer.Methods From January 2005 to May 2013,among 658 patients with achalasia,the clinical data,pathological characteristics of tumor and the treatment of those complicated by esophageal cancer were collected and analyzed.At the same time,receiver operating characteristic (ROC) curve analysis was performed to analyze the relationship between the course of achalasia and esophageal cancer.Results Among the 658 patients with achalasia,297(45.1%) cases were male and 361(54.9%) cases were female.A total of 62 cases (9.4%) were lost to follow-up and of 596 cases who completed the follow-up,26 cases (4.4 %) were complicated with esophageal cancer.Among the 26 patients complicated with esophageal cancer,69.2% (18/26) were male;the course from achalasia diagnosed to esophageal cancer was (16.5±8.2) years.The patients with a disease duration more than 10 years accounted for 88.5%(23/26),and 80.8% (21/26) underwent previous balloon dilatation or Heller surgery.The predilection site of esophageal cancer was in the middle esophagus of patients complicated by esophageal cancer (69.2%,18/26),the main type was squamous carcinoma (88.5%,23/26),65.4%(17/26) of the lesions invaded to muscular layer (stage T3 to T4),61.5%(16/26) had the late stage tumor (stage Ⅲ to Ⅳ),and 23.1%(6/26) had distant metastasis.The results of ROC curve analysis showed that when the duration was 10.5 years,the Youden index reached the maximum value (0.71).And 38.5% (10/26) of patients with esophageal cancer could not be treated with esophageal cancer radical surgery,and their average survival time was (11.4±6.6) months.Conclusion The patients with the duration of achalasia over 10.5 years are required for regular endoscopic examination to improve the prognosis.
