Objective: To investigate the practicability and safety of transjugular liver biopsy (TJLB). Methods: Data of 53 cases with transjugular liver biopsy from June 2015 to June 2020 were collected. LABS-100 was used in all patients who underwent transjugular liver biopsy. Among them, 45 cases and eight were biopsied via hepatic vein and intrahepatic segment of the inferior vena cava. The surgical indications, related complications, and postoperative pathological diagnosis were analyzed and summarized. Results: TJLB was successful in all patients, with an average of 2.8 punctures per case. Satisfactory liver tissue and histopathological diagnosis was obtained in all patients. Two cases developed a cervical hematoma that was improved spontaneously, and one patient developed an intrahepatic hematoma that was improved after conservative treatment. Conclusion: TJLB is a practical and safe method for patients with contraindications to percutaneous liver biopsy.

<p><b>AIM</b>To synthesize four water-soluble metal porphyrins [5, 10, 15, 20-tetra[4-(4'-pyridine-1) butyloxy phenyl] metalloporphyrins bromide, metal = Zn (I), Cu (II), Mn (III) and Co (IV)] as analogous enzyme having two anti-active oxygen functions.</p><p><b>METHODS</b>The first function, scavenging O2-, has been proved by using riboflavine-methionine photoreduction methods. The second function, scavenging H2O2, has been demonstrated by using the oxidating Vit C. The third function, scavenging HO*, has been demonstrated by using Fenton reaction. The complexes were measured by the mice liver homogenate technique of mice.</p><p><b>RESULTS</b>Four model compounds could scavenge O2- in the concentration range of 1.0 x 10(-5) - 1.0 x 10(-6) mol x L(-1), decompose H2O2 in the concentration of 1.5 x 10(-6) - 1.0 x 10(-6) mol x L(-1), scavenge HO* in the concentration of 2.0 x 10(-8) - 1.0 x 10(-8) mol x L(-1). All showed that they had obvious action of decreasing the lipid peroxidation in the concentration of 1.0 x 10(-7) mol x L(-1).</p><p><b>CONCLUSION</b>All above-mentioned complexes were considered to be qualified analogous enzymes of anti-active oxygen.</p>

Objective To investigate the clinical features and management of pancreatic disease- associated portal hypertension.Methods A retrospective analysis was carried out in patients with portal hypertension complicating with pancreatic diseases in our hospital from January 1986 to April 2005. Medical records of these patients were reviewed,including data of demographics,etiologies,venous involvement,clinical presentation,laboratory tests,imaging studies,therapeutic modalities and out- comes.Results There were 59 cases of portal hypertension resulted from pancreatic diseases in our hos- pital,accounting for 4% of all portal hypertension in 19 years.The underlying pancreatic diseases were chronic pancreatitis(21 cases,35.6%),pancreatic carcinoma(20 cases,33.9%),acute pancreatitis (8 cases,13.6%),pancreatic pseudocyst(3 cases,5.1%).Of the 40 patients whose venous involve ment was identified,splenic vein obstruction occurred in 27 cases(67.5%),followed by portal vein obstruction(16 cases,40.0%).Mild or moderate splenomegaly was present in 48 cases(81.4%),with leukocytopenia as the most common manifestation of the 31 cases(52.5%)of concomitant hyper- splenism.Forty-five patients(76.3%)developed gastroesophageal varices(including 35 isolated gastric varices),among them,19 had bled(32.2%).Conservative treatment was effective in controlling acute bleeding,but could not prevent re-bleeding.Splenectomy was performed in 18 patients,mainly because of gastrointestinal hemorrhage.No postoperative bleeding occurred in the period of follow-up from 8 months to 9 years.Conclusions Pancreatic diseases may compromise portal vein and its tributaries, leading to generalized or regional portal hypertension.Pharmacological therapy can effectively control acute variceal bleeding,while surgical treatment is the appropriate procedure of choice in case of hemor- rhage recurrence.
