By applying the thrombo pre molecular markers, including plasmal GMP - 140, tPA, PAI - I TAT, PAP, ET, their correlation with blood stasis type diabetes were explored. Results showed that, the diabetic with blood -stasis type revealed the activation of platelets, injury of endothelial cells, changes of fibrinolysin. Their plasmal GMP-140, TAT, PAP, ET were all higher than that of the control group, indicating that the activation of platelets, injury of endothelial cells, and changes in the balance of blood coagulation/fibrinolysis are likely to benefit the incidence of blood stasis. The pathophysiological mechanism in blood stasis type diabetes is related to the changes in platelet, endothelial cells, blood coagulation and fibrinolysis.

Platelet a - GMP - 140, ET were used as indices of activation of platelet, functional injury to endothelial cells. Cardiovascular diseases, nephropathy and II type diabetes were selected forobservation. Results showed that the plasmal GMP-140 and ET were all markedly higher than that of the controlled group (P

Objective To investigate the effect of LF on blood biochemistry,cytokines in rats with NASH in order to approach possible mechanism of LF against NASH.Methods 50 male SD rats were randomly divided into the normal control group(10 rats),the model group(10 rats),the Essentinale group(10 rats)、the LF high dose group(10 rats)and the LF low dose group(10 rats).Except for the normal control group which was raised by standard animal feeds,others were all raised by high fat feeds to make NASH model and administered by Essentinale,high dose LF and low dose LF for 12 weeks.Hepatic lipid contents,plasma TG,CHO,HDL-C,LDL-C,ALT,AST and TNF-?,FFA,Leptin concentrations were evaluated,as were histopathological changes in the liver.Results In this NASH model,the liver FZ(liver weight /body weight),plasma CHO,LDL-C,ALT,AST and TNF-?,FFA,Leptin concentrations were higher than that in normal control group,but the levels of serum HDL-C and TG were reduced.In addition,the histopathological showed increased fatty droplets within hepatocytes and liver inflammation.The levels of serum ALT,AST,HDL-C,TNF-?,Leptin,FFA and hepatic CHO,TG contents in the LF high dose group and LF low dose group were reduced compared with that in the model group,while the levels of serum TG,HDL-C were enhanced remarkably.In addition,liver inflammation was improved evidently.Conclusions Treatment with LF might improve non-alcholic steatohepatitis,because LF inhibits the elevation in the level of plasma cytokine.

Objective To investigate the differences in myocardial deformation between donor and recipient in twin-twin transfusion syndrome(TTTS) using vector velocity imaging( VVI). Methods Digital dynamic two-dimensional four chamber views were interrogated off-line using VVI software. Global longitudinal strain(S) , systolic strain rate(SRs) and diastolic strain rate(SRd) were measured in the left ventricles(LV) and right ventricles (RV) of 30 fetal pairs with TTTS and compared to 30 gestational age-matched normal controls. Results Donor LV-SRs was higher, while donor RV-SRd was significantly lower than controls. Recipient S, SRs and SRd were significantly lower for both LV and RV in comparison to controls. Conclusions In TTTS,donor LV systolic function is hyperdynamic while the RV diastolic function is low. Recipient RV and LV are both globally depressed with systolic and diastolic dysfunction.

Objective: To investigate the curative effects of Shuanghongtong Decoction (Flos carthami, Radix Ginseng Rubra and Radix Ophiopogonis) diabetic neuropathy peripheral (DPN) and its mechanism.Methods:28 DPN patients were treated with Shuanghongtong Decoction for 3 weeks. The symptom and the peroneal nerve conduction velocity (SNCV) were observed before and after the experiments respectively. The diabetic rats reduced by STZ were treated with the same decoction for 4 weeks, at the end of the experiments the nerve conduction velocity (NCV) and the activity of aldose reductase (AR) were measured.Results: Some symptoms such as acra pain, numbness, asthenia and the peroneal SNCV were significantly improved after treatment with decoction. The animal experiments showed that the NCV were significantly increased and the activity of AR significantly decreased in diabetic rats as compared with the normal rats.Conclusion: Shuanghongtong Decoction could improve the symptom and increase the NCV of DPN. It's mechanism may be through inhibiting the activity of AR then improving the diabetic metabolism disorder.

Objective To investigate drug resistance and genotypes of methicillin-resistant Staphylococcus aureus (MRSA) isolated from intensive care unit (ICU). Methods MRSA strains were isolated from patients, medical staff and environment of hospital ICUs. Disk diffusion (K-B method) was used for drug resistance testing; Staphylococcal cassette chromosome mec (SCCmec) and Staphylococcal protein A (spa) typing methods were used for genotyping and identifying the homology. Results There were 78 strains of Staphylococcus aureus isolated including 62 isolates of MRSA, which were mainly from the burn ICU (22, 35.48%). Among 62 MRSA strains, 50 were hospital acquired strains, in which 43 isolates were of SCCmec Ⅲ, 4 of SCCmec Ⅰ and 3 of SCCmec Ⅱ. Twelve isolates could not be typed. Twenty-eight out of 37 hospital acquired isolates were typed by spa typing as SCCmec Ⅲ-t030, which belonged to the same clone. Conclusion MRSA in ICU is multi-drug resistant and SCCmec Ⅲ-t030 is the most prevalent genotype, which indicates that clinical MRSA strains and environmental MRSA strains may be homologous.

Objective To investigate protection by immunization with recombinant Ferritin vaccine of Echinococcus granulosus against protoscolices.Methods ICR mice were randomized into 3groups of 12 mice in each.The mice in group A and B were immunized three times with an interval of two weeks and those in group C did nothing.The animals in all the 3 groups were challenged with 1100 protoscolices intraperitoneally on the 8th week.Serum samples were collected before each inoculation and challenge injection.Seven months later, all the mice were killed and examinated for hydatid cysts.Result The number of cysts was significantly lower in the group A than in group B and C (P＜0.05).The levels of protection afforded were found to be 73% and 85%, respectively.Meanwhile,the number of cysts was markedly lower in group B than in group C(P＜0.05).The rate of protection afforded was 42%.Conclusion Recombinant Ferritin vaccine of Echinococcus granulosus shows partial immune protection.Therefore, it might be a suitable candidate for cocktail vaccine study in the future.

Objective To develop a sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) method for the determination of forsklin in rat plasma.Methods After extraction with methyl tert-butyl ether,chromatographic separation was performed on a C18 column with the mobile phase consisting of water ( 0.1％ formic acid)-acetonitrile in a gradient elution mode.A tandem mass spectrometer equipped with electrospray ionization (ESI) source was used as detector in the positive ion mode.Quantification was performed using multiple reaction monitoring (MRM) with the precursor product combination ions of m/z 411→375.3 and 285→193 for forsklin and diazepam.Results Good linearity was obtained in the 0.5-1000 ng/ml range for the analyte and the analytical method was validated in terms of specificity,precision,accuracy,recovery,stability and matrix effect.These assays gave RSD values always lower than 14.4％ and RE values between -3.5 ％ and 3.8％.In addition,the specificity,extraction recovery,stability and matrix effect were satisfactory.Conclusion Due to its high sensitivity,specificity and simplicity,the method could be used for pharmacokinetic studies of forsklin.
