Objective To explore effects of hcmoperfusion on toxic ingredients in plasma of rabbiis with a-cute intoxication of Radix Aconiti Kusmezoffii Monkshood.Method Sixteen male Japanese Giant Ear Rabbits were randomly divided into acute poisoning(AP)group and acute poisoning + hemoperfusion(AH)group(8 an-hnals in each group).Acute poisoning models were established in rabbits of both groups with intragastric adminis-tration of Radix Aconiti Kusmezoffii Monkshood liquid in dose of 1 mL/kg in order to produce arrhythm which oc-curred within ode hour after intragastric administration was regarded as the criteria of successful animal model.and then hemoperfusion with active carbon was performed for 2 hours in AH group.The pathological chanses of brain,myocardium and hepatic tissues were observed.The plasma concentrations of toxicants including mesaconitine,a-conitine and hypaconitine were measured by using HPLC-MS at 1 h,2 h,3 h,and 6 h after poisoning.Student's T test was used to identify the significance.Results The brain.myocardium and hepatic tissues of the rabbits in AP group showed hyperemia and edema which were attenuated after hemoperfusion.The plasma concentrations of mesaconitine,aconitine and hypaconitine revealed no significant differences between AP group and AH group with-in one hour after poisoning(P>0.05),while at 2 h and 3 h after poisoning,the plasma concentrations of mesaconitine were(2.11±1.08)ng/mL,(2.02±1.46)ng/mL,respectively,aconitine(39.70±9.31)ng/mL,(19.71±16.06)ng/mL,respectively,and hypaconitine(1.70±0.71)ng/mL,(2.12±1.33)ng/mL,respec-fively in AH group,and they were significantly lower than those in AP group(P<0.05).Conclusions The the plasma concentrations of mesaconitine,aconitine and hypaconitine were lower and the histopathological changes were attenuated after hemoperfusion.Hemoperfusion is a good intervention for acute intoxication of Radix Aconiti Kusmezoffii Monkshood.

Objective To obtain a lasting and purified cell line of vascular smooth muscle cells (VSMCs) by primary culture, and to provide these test materials related research. Methods The primary and transfer culture was done by tissue - piece inoculationand trypsin digestion,respectively. The cells were frozen in liquid nitrogen,and cultured cells were identified by phase contrast microscopy and immunohistochemical SP kit. Results 85% of inoculated tissue pieces survived. More than 90% of VSMCs regrew in transfered culture. The frozen cells could recover their proliferation by several culture transfers. The VSMCs showed the typical "peak and valley" characteristics under microscopy. Immunohistochemical staining with antibody against SM - a - actin expression in these cells was positive. Conclusion The tissue - piece inoculation is a simple method for obtaining satisfactory VSMCs in short term.

By software and signal analysis,visualization of medical NMR signals becomes possible.The T1,T2 resonance frequency value reflecting human tissue characteristics,and the FID,echo wave as well as other curves reflecting the intensity of signals,can contribute a lot to the teaching of the applied analysis of clinical NMR and MRI principles.

Objective To observe the poisoning components in plasma and histological changes of rabbits with acute toxicity of aconitum kusnezoffii (草乌).Methods Eight rabbits were garaged with aconitum kusnezoffii liquor,aconitum poisoning model was reproduced,electrocardiogram (ECG) and blood pressure were recorded,the concentrations of aconitine,hypaconitine and mesaconitine in plasma after 0.5,1, 2,3 and 6 hours were measured,and the pathological changes of heart,liver and cerebral cortex were observed.Results After garage with poisoning liquor,arrhythmias and the declination of blood pressure, presenting a tendency of progressive aggravation [before garage:(121.98?16.77)/(110.66?8.78) mm Hg, 1 hour after garage:(102.98?8.34)/(90.22?5.85) mm Hg,2 hours after garage:(66.81?9.13)/ (53.40?6.32) mm Hg,1 mm Hg=0.133 kPa,all P

Objective To investigated the serum level of carcinoma antigen 125 (CA-125) and its clinical significance in patients with Budd-Chiari syndrome.Methods We reviewed medical records and laboratory tests of patients with BCS first diagnosed in our hospital between August 2011 and April 2013.235 patients were included as experiment group,while 120 healthy adult volunteers were randomly selected as control group.The serum level of CA-125 were detected by electrochemilumescence immunization assay in this single-center retrospective control study.Results The average serum level of CA-125 in experiment group is higher than that of control group [(147.9 ±246.6) kU/L vs (16.0 ±7.2) kU/L,P <0.001].In experiment group,the relative coefficient for serum CA-125 with ascites,alanine aminotransferase,aspartate aminotransferase,albumin and Rotterdam BCS scores was 0.79,0.45,0.29,-0.393 and 0.71,respec tively,P <0.001.As of October 2013,we found that the 68 BCS patients with serum CA-125 level 5-fold higher than the upper limit of normal (> 175 kU/L) presented much lower survival rates and asymptomatic survival rates than the rest 167 BCS patients after intervention therapy:(95.6% and 79.8%) vs (98.8% and 92.0%),P < 0.05.Conclusions The serum level of CA-125 in BCS patients have positive correlation with ascites volume,liver injury degree and Rotterdam BCS scores.Serum CA-125 evaluation appears to be a valuable examination option in BCS as CA-125 levels negatively correlate with worse prognosis,thus could be applied as an efficient tool for prognostication.

Objective To investigate clinical features,treatments and prognostic factors of the patients with necrotizing fasciitis caused by vibrio infections and thus provide reference for the early treatment and prognostic assessment.Methods A retrospective analysis was conducted on clinical data of 56 patients with vibrio necrotizing fasciitis admitted to the emergency center of our hospital from May 1995 to June 2011.The clinical characteristics and treatments of the patients were summarized,and differences of clinical factors between the survival group and death group were compared.The possible influencing factors for prognosis were also analyzed.Results The main clinical manifestations included fever (61%),shock (84%) and organ dysfunction,of which renal insufficiency (88%) was the most common,with case fatality of 43%.Early pathological changes of limbs were only local swelling and pain,while skin ecchymosis,tension blood blisters,necrosis and subcutaneous crepitation were the signs of advanced stage.Comprehensive treatment regime including early administration of sensitive antibiotics plus surgical incision and drainage and medicine support was given.A series of factors were significantly different between the survival and death groups including the duration from the presentation of symptoms to hospital admission (P < 0.05 ),limb lesions involving the trunk (P < 0.01 ),creatine kinase level (P < 0.05 ),and emergency incision and drainage ( P < 0.01 ).Conclusions The most prominent clinical manifestations of vibrio necrotizing fasciitis are rapidly progressive local symptoms and signs,and sharp deterioration of systemic conditions.Delayed visiting,severe local lesions,and failure to emergency surgery may be the factors for poor prognosis.
