Arterial thrombosis (AT) is a common disease which usually causes acute myocardial infarction,ischemic stroke and other ischemic cardiovascular and cerebrovascular diseases,which shows high rates of morbidity and mortality,and has become a serious problem to human health.It is increasingly clear that the interactions among platelets,the endothelium and leukocytes are important throughout all stages of the atherothrombotic process.It is of great significance to search for therapeutic targets in the process of AT and developing the therapeutic drugs based on those newly discovered targets.This article reviews the research advances in the discovery of antithrombotic targets and the current situation of drug development based on those antithrombotic targets found in the recent 5 years,in order to provide some references or clues for the development of innovative drugs to prevent and treat AT.

Objective To investigate the dynamic change and different apoptosis of T lymphocyte subsets in patients with acute pancreatitis.Methods Forty-four patients with MAP and 32 with SAP were enrolled in this study.Blood samples were collected on the lst,3rd and 7th d after onset.T lymphocyte subsets and their apoptotic rate were determined by flow cytometry.Results Compared with the control group and MAP group,CD4+ T lymphocytes and the ratio of CD4+/CD8+remarkably decreased while the apoptotic rate of CD4+ T cells significantly increased in patients with SAP.However,there was no marked difference in apoptotic rate of CD8+ T cells among different groups.Conclusion The different apoptosis of T lymphocyte subsets in AP,especially in SAP,results in severe and sustained cellular immune suppression.

Capillary gas chromatographic column 1 (7.5%　W/W,3 5×0. 35mm i.d.) and column 2 (9.2% W/W,35×0.30mm i.d.) using butylammonium 4-to unesulfonate as stationary phase were prepared by the method of dynamic coating with mercury plug, and the solvent used was mixture of acetone and methanol (2 ∶1　V/V). The results　showed that the column had good chromatograpic pro perties, especially to strong polar compound, such as carboxylic acids and acoho ls could be separated well.

Objective: To develop and prepare oral rehydration salt powder II (ORS II) effervescent tablets. Methods: Taking the mass/tablet, rigidity, disintegration time, and pressing status as the main indicators, we optimized the formulation and preparation process of the effervescent tablet by single factor test. The character, identification, disintegration time, acidity, and content determination of the tablets were also investigated. Results: It was found that the optimized preparation process of the effervescent tablets was to mix the acid part, which was granulated with ethanol, with the base part, and then compressed the mixture. The optimal formula was composed of: NaCl (11.5%), KCl (4.93%), C6H8O7 (6.21%), NaHCO3 (8.15%), C6 H12 O6 (65.7%), and PEG-6000 (3%). The rigidity of the prepared effervescent tablet was 4.5 kg and the disintegration time was 175 s. Conclusion: The formulation of the present product is consistent with the corresponding Chinese Pharmacopoeia monograph, requiting no additional effervescent; the preparation process is simple and the products are stable, and the product my be developed into a new oral rehydration salt formulation.

ObjectiveTo study the relationship between the expression of carbohydrate antigen 72-4(CA72-4) in pathology negative lymph nodes from patients with gastric carcinoma and micrometastases. MethodsA total of 385 perigastric negative lymph nodes from 65 patients were immunohistochemically stained with tumor-associated glycoprotein by S-P. ResultsThe lymphatic micrometastases of gastric carcinoma were identified in 14 of 65 patients (21.5%) and in 26 of 385 negative-nodes (6.8%). The incidence of micrometastases was significantly higher in patients with diffuse type than intestinal type(35.5% vs. 8.8%,P

ObjectiveTo explore more effective and lower expensive approach for aplastic anemia(AA).Methods A prospective,randomized clinical trial was conducted to determine whether the outcome of AA patients treated with the combination of securinine plus anisodamini dripping in bone marrow(therapy group)was better than that with anisodamini alone dripping in vein(control group).Results The cure remission rate(83.3%) and the response rate(94.4%) of therapy group were significantly higher than that of control group(11%,55.6%, P

Nucleic acid aptamer is an oligonucleotide generated by the systematic evolution of ligands by exponential enrichment (SELEX)process from oligonucleotide library.Nucleic acid aptamer can bind to various targets with high specificity and can recognize or inhibit the biological activity of targeting molecular. Glioma-specific aptamers are developed by either targeting the glioma cells or known biomarkers,which can be coupled with nanoparticles,drugs or molecular probes,and can be applied in the imaging,targeted therapy and drug delivery of glioma.

Objective To explore the feasibility of establishing the model of chronic blliary(pancreatitis) by incompletely ligaturing common bile duct.Methods Fifty Wistar rats were randomly(divided) into three groups: control group,experimental control group and model group.The rats in model group were exposed the root of common bile duct to enter duodenum using the dissolubility bowel line to ligating a needle with common bile duct,then drew out the needle,closing the abdominal cavity.The rats in experiment control group were opened the abdominal cavity and dissociated common bile duct,then closing the abdominal cavity.Results Compared with control group,the serum bilirubin and(amylase) of blood in model group were increased in 3 days and 14 days respectively and fibrotic(proliferation) of pancreatic tissues were found in 30 days.In model group,23% of rats developed(pancreatic) pseudocyst.Conclusions Incompletely ligating the common bile duct of Wistar rats could(induce) chronic pancreatitis and pancreatic fibrosis in 30 days.Strictures of common biliary duct may play a key role in chronic biliary pancreatitis.

Objective To observe the curative effect of using artificial liver bilirubin specific adsorption for treatment of patients with hyperbilirubinemia and its effect on nursing.Methods A prospective study was conducted, 146 patients with hyperbilirubinemia admitted to Mianyang Central Hospital from January 2015 to December 2016 were enrolled, and they were divided into an observation group (77 cases) and a control group (69 cases) according to random number table method. The observation group was treated by medical treatment and the artificial specific liver bilirubin adsorption, while the control group only treated by medical therapy. The changes of levels of liver function indexes alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), direct bilirubin (DBil) before and after treatment and clinical curative effect were observed in the two groups.Results Before treatment, there were no statistical significant differences in levels of the ALT, AST, TBil, DBil between the two groups (allP > 0.05), after treatment, the above indexes were significantly decreased compared to those before treatment, and the degrees of decrease in observation group were more obvious than those in control group [ALT (U/L): 341±42 vs. 455±37, AST (U/L): 120±35 vs. 197±37, TBil (μmol/L): 185.4±20.6 vs. 302.6±30.6, DBil (μmol/L): 42.6±10.8 vs. 87.5±11.6, allP < 0.05]. The total effective rate in observation group was obviously higher than that of control group [62.3% (48/77) vs. 40.6% (28/69),P < 0.05].Conclusions Based on liver protection, symptomatic and supportive medical treatment, using artificial liver bilirubin specific adsorption for treatment of patients with hyperbilirubinemia is safe and effective, and in addition, close observation and careful nursing is beneficial to the reduction of incidence of complications and elevation of therapeutic efficiency.

Objective To observe endothelial and fibrinolytic functions of atrial fibrillation(AF)dogs induced by chronic rapid atrial pacing and effects of cilazapril on it and to investigate the mechanism of thrombogenesis in AF.Methods From January to August of 2004,16 dogs were randomly divided into control group(n=8)and cilazapril group(n=8).All dogs were paced at 400 bpm for 6 weeks by AOO pacemaker.The dogs in cilazapril group received cilazapril(1mg?kg-1?d-1)from 1week before pacing to 6 weeks after pacing.Plasma angiotensinⅡ(AngⅡ),von Willebrand factor(vWF),tissue-type plasminogen activator(t-PA)and plasminogen activator inhibitors-1(PAI-1)level were measured before and after rapid pacing respectively.Results After rapid atrial pacing,plasma AngⅡ,vWF,t-PA and PAI-1 level increased significantly in control group dogs(AngⅡ:(349.9?28.3)ng/L vs(198.4?19.4)ng/L,P
