Objective:To detect differences in results of routine biochemical indexesand serum anticoagulant heparin, explore the feasibility of plasma heparin in the emergency biochemical test in.Methods: Two hundred cases of patients in the emergency department of our hospital as the research object, peripheral venous blood samples, were installed on the ordinary drying tube and a heparin plasma in vitro, determination of 10 emergency patients in serum and plasma biochemical items using biochemical analyzer, comparative analysis of the effect of heparin plasmabiochemical test results, and to compare the two groups report time.Results: The difference of serum group and Mg2+ group, Cl-, plasma Ca2+, Cr, BUN, UA, ALT, GLU and other data is not obvious, no statistical significance, The plasma concentration of K+ group was significantly lower than serum group, serum concentration of Na+ was higher than group difference was significant, with statistical significance(t=8.167,t=4.361;P<0.05). Plasma group reported significantly less than the serum group(t=22.94,P<0.05).Conclusion: heparin sodium does not dissolve in the blood, with a strong ability for anticoagulation, emergency biochemical test can avoid the effect of blood coagulation test results, and shorten the time for patients toreport, to win the precious time, attention is needed to correct potassium ionconcentration difference test.

Objective To compare the treatment effects of catheter directed thrombolysis and thrombetomy for acute ar?terial ischemia of the lower extremity. Methods Patients who visited Tianjin Medical University General Hospital from 2011 to 2013 and were attacked by acute ischemic disease of lower extremities within 3 days (n=66) were investigated. Thrombetomy and thrombolysis treatment had been performed to 32 cases and 34 cases respectively according to patients’ own willingness. Postoperative symptom remission rate, limb salvage rate, fatality rate, reperfusion injury rate (including re?nal inadequacy, heart failure, muscle fascia compartment syndrome), bleeding rate and limb dysfunction rate were compared between these two groups. Results There was no statistical difference on the rate of symptom remission (93.8% vs 94.1%), limb salvage(96.9%vs 100%), case fatality rate(3.1%vs 0), bleeding rate(0 vs 8.8%)and limb dysfunction rate (0 vs 5.9%)between these two groups. However, the incidence of reperfusion injury was higher in the group of thrombectomy (37.5%vs 2.9%, P<0.05)compared to that of the other group. Conclusion Similar effect of treatment and less reperfusion injury, especially renal injury, had been achieved by CDT compared with thrombetomy.

OBJECTIVE: Apolipoprotein (Apo) E- ε 4 is the first identified important susceptible gene of late-onset family and sporadic Alzheimer disease. Apo E E4 or ε 4 chained other genetic products probably play a certain actions in occurrence of Alzheimer disease, but their biological basis is unknown.To explain the relevant biological mechanism between ApoE and Alzheimer disease is still the key in next study.DATA SOURCE: Computer Medline database is used to search the relevant papers from January 1978 to January 1999, with the words of "develop", "ApoE" and "Alzheimer", limited in English version. Simultaneously, the relevant papers are looked up from China Journal Databasefrom January 1978 to December 2003, with the words of "ApoE, Alzheimer disease and development", limited in Chinese version.STUDY SELECTION: Preliminary examination is done to the data. Inclusive criteria: relevant papers on ApoE gene and Alzheimer disease, including the study of both animal experiment and clinical basic research.Exclusive criteria: repeated study, summarized and Meta analysis papers.DATA EXTRACTION: Totally 55 relevant papers are collected, of which, 20 papers are included and 33 papers are excluded due to repeated experiment and summarized papers.DATA SYNTHESIS: Of 20 experiments, 16 experiments explain that ApoE E4 or ε 4 chained other genetic products probably play a certain actions in occurrence of Alzheimer disease and 4 researches propose that ApoE- ε 4 is the susceptible gene of Alzheimer disease.CONCLUSION: It is viewed in majority at present that ApoE genotype determination cannot substitute any clinical and imaging diagnostic method, which is probably onlya kind of assistant diagnosis to improve the specialty in clinical diagnosis. Beingthe susceptible gene of Alzheimer disease, ApoE- ε 4 is the important discovery in its research no doubt, but,many relevant questions are still at experimental and hypothesis stages. In the future, the great consideration should be still drawn on ApoE genotype determination of Alzheimer disease.

Objective To investigate the effect of aminoguanidine and tienam on bacterial translocation in mice with acute necrotizing pancreatitis (ANP) and the preventive and curative effect on pancreatic infection. Methods 50 SD mice were randomly divided into 5 groups, including group A: normal control (n=10), group B: ANP group (n=10), group C: aminoguanidine treatment group (n=10), group D: tienam treatment group (n=10), and group E: aminoguanidine plus tienam treatment group (n=10). ANP was induced by intrapancreatic injection of 5% sodium tanrocholate (2.5 ml/kg). Aminoguanidine (100 mg/kg) was injected intraperitioneally 30 minutes after ANP induction, tienam (60 mg/kg) was injected intraperitioneally 6 hours after ANP induction. The mice were killed at 48 hours, and serum amylase, serum D- lactate, pancreatic MPO were measured. Pathological alterations in the pancreas were examed. The pancreas, liver, blood, mesenteric lymph node and ascites were collected for microbiological study. Results In group C and E, the levels of serum amylase were 91173.30±199.73) U/L and (1075.00±200.40) U/L; the serum D-lactate were (7.165±1.2533) μg/ml and (6.980±1.060)μg./ml; the pancreatic MPO were (0.8035±0.0711) U/g wet film and (0.7765±0.0843 ) U/g wet film; the average bacterial positive rates were 20% and 16%. In group B, the serum amylase was (2234.60±692.06 )U/L;the serum D-lactate was (12.408±1.779)μg,/ml, the pancreatic MPO was (1.5942±0.1965) U/g wet film; the average bacterial positive rate were 60%. The differences between group C, E and group B were statistically significant (P＜ 0.05). In group D, the pancreatic MPO was (0.8002±0.0603 ) U/g wet film and the the average bacterial positive rate was 18%, and they were statistically different when compared with those of group B (P±0.05). While in group D, the serum amylase and D-lactate was not statistically different when compared with those of group B (P＞0.05). There were lamellar necrosis in the parenchyma, hyperaemia and leukocytic infiltrate in the pancreatic mesenchyma in the ANP group, while no leukocytic infiltrating in group C, D, E was found. Conclusions The aminoguanidine and tienam might decrease gut bacterial translocation and prevent pancreatic infection in ANP.

The evaluation of biomaterial biocompatibility is a key step before the clinical application.With the rapid development of molecular biology,scientists have begun to evaluate biomaterial biocompatibility at molecular level and proposed the concept of molecular biocompatibility.Researchers'main tasks at present are to identify more molecular markers using molecular biology technology and to establish standards for evaluating molecular biocompatibility of biomaterial,which will provide the guidance for the design of better biomaterials.

There are a number of potassium channels on the cerebrovascular smooth muscle cell membrane, generally they are divided to 4 categories: voltage-gated potassium channels, calcium-activated potassium channels, inward rectifier potassium channels and ATP sensitive potassium channels. They can modulate cerebrovascular tone, so as to impact on cerebral blood flow to adapt to different situations of physiological pathology. The structure and function of potassium channels change after subarachnoid hemorrhage, These changes may be associated with the occurrence and development of cerebral vasospasm. The application of potassium channel opener may relax cerebrovascular smooth muscle and attenuate cerebral vasospasm.

β-catenin is an important signaling transduetion and adhesion molecules.Mutation of the betacatenin gene,CTNNB1,is a common case in pediatric tumors,which may induce development and metastasis.In hepatoblastoma,48%have CTNNB1 mutation.In Wilms tumor,mutation only occurs in cases with WT1 gene mutation.In neuroblastoma,mutation is also found.
