Objective To analyze the diagnosis and treatment of pancreatic trauma with main pancreas duct break. Methods Forty-four cases of severe pancreatic trauma with main pancreas duet break were retrospectively analyzed including their diagnosis and different operation performed according to the severity of pancreatic trauma. Results All of severe pancreatic trauma could be diagnosed by CT scan and B-ultrasonic examination. But the main pancreas duct break or not should be determined by surgical exploration. Emergency operations were performed for all cases , distal part pancreaticojejunostomy in 27 cases; modified duodeno-divertiulaization in 3 cases, duode-nojejunostomy in 3cases, pancreaticeduodenectomy in 2 cases, 41 cases were cured. The mortality was 6.8%. Conclusion CT scan is the most helpful means to diagnose pancreatic trauma. An appropriate and timely emergen-cy operation is the key to reduce mortality.

Objective To retrospectively analyze the treatments of nonvalvular atrial fibrillation (nvAF) in elderly patients aged 80 years and over,and to investigate the influencing factors for occurrence of stroke and transient ischemic attack(TIA)and relationships between antithrombotic therapy and stroke or TIA.Methods 101 elderly patients with nvAF were enrolled and grouped according to the occurrence of stroke/TIA and antithrombotic-correlated bleeding.The influencing factors were retrospectively analyzed and antithrombotic schemes were compared.Results Incidence rate of stroke/TIA was 28.7％ (29/101).Among all patients,70 cases were treated with antiplatelet therapy,19 cases were treated with anticoagulation therapy,while 12 cases received no antithrombotic (antiplatelet or anticoagulation) therapy before stroke.Both the nvAF time course and the antithrombotic strategy were significantly different between post-AF stroke/TIA group and non-postAF stroke/TIA group(both P＜0.05).The difference was reflected in ratios of antiplatelet therapy/anticoagulation therapy.The proportion of anticoagulation therapy was higher in non stroke/TIA group(x2 =5.778,P =0.016).Different antiplatelet therapy scheme significantly affected occurrence of stroke/TIA(P＜0.05).There was no significant effect of antithrombotic schemes on hemorrhagic events(x2=0.708,P =0.702).Multiple logistic regression analysis showed that hypertension,coronary heart disease,cancer,diabetes and previous stroke history,as well as nvAF duration were the independent risk factors for post-AF stroke/TIA(OR=1.351,95 ％CI:1.129-1.617).Conclusions Currently,the proportion using anticoagulation therapy is low,and single antiplatelet therapy is the main regimen in the elderly patients with nvAF.For elderly patients with nvAF,anticoagulation therapy has a protective effect against the occurrence of post-nvAF stroke/TIA,meanwhile there is no significantly increased risk of bleeding,which makes anticoagulation therapy advisable in the elderly.The nvAF time course is one of the risk factors,which is worth experts' attention in risk evaluation of thrombus in elderly patients.

Investigation of simvastatin and its related substances was carried out using a reversed phase ultra performance liquid chromatography/tandem mass spectrometry method. The identification of impurities in simvastatin was performed with a triple-quadrupole mass spectrometer, with an electrospray ionization (ESI) source in the negative/positive ion mode. A total of 12 compounds were characterized in commercial samples, among which 2 impurities had never been reported. All the impurities were deduced based on the MS fragment pathways of simvastatin and the biosynthetic pathway of lovastatin. This work provides very useful information for quality control of simvastatin.

OBJECTIVETo explore the role and mechanism of oxidative inflammatory cascade in pancreatic fibrosis progression of chronic pancreatitis (CP) in mice induced by dibutyltin dichloride (DBTC) plus ethanol.

METHODSThirty-six KM mice were randomly divided into 2 groups (n = 18): control group and model group (DBTC combined with ethanol). The mice in model group were intravenously injected with DBTC (8 mg/kg) in tail vein and drink 10% ethanol. After modeling 2 weeks, 4 weeks and 8 weeks, the mice were anesthetized and sacrificed, the pathological changes and the degree of fibrosis in the pancreas were observed by HE and Masson staining, the F4/80 expression level were detected by immunohistochemistry, the content of superoxide dismutase (SOD), malondialdehyde(MDA) and myeloperoxidase (MPO) were measured in the pancreatic homogenates.

RESULTSThe fibroblasts and macrophages (f4/80 positive staining) could be seen obviously in pancreas of model group at 2 weeks. At 4 weeks and 8 weeks, macrophages infiltration increased and pancreatic tissue was substituted by the proliferation of fibrosis significantly. At every time-point, in pancreatic homogenates SOD was decreased, MDA and MPO markedly increased. There was significant differences between two groups (P < 0.05).

CONCLUSIONDBTC injection joint ethanol drinking can successfully establish the model of chronic pancreatitis and pancreatic fibrosis in mice. Oxidative inflammatory cascade plays an important role in the progression of pancreatic fibrosis.
