METHODS: The initial average rate stability test was performed at 7 different temperatures to investigate the relationship between the initial average rate (V0) of the glucose degradation reaction and Kelvin's temperature (1/T), and the activation energy of reaction, the drug reaction velocity constant and shelf life were computed as well. RESULTS: The regression equation was lgV0=18.15—6 774.6?1/T(r=—0.937 5), the reaction activation energy was 31.0Kcal?mol-1, the drug reaction velocity constant at 20℃ was 1.1?10-5h-1, and the shelf life was 1.09 years. CONCLUSION: The method is simple and it can accurately predicate the shelf life of compound sodium citrate injection.

Objective To investigate the effect of insulin combined with Edaravone therapy on delayed cerebral vasospasm (CVS) after experimental subarachnoid hemorrhage (SAH).Methods 40 New Zealand white rabbits were randomly separated into sham-operated group (n=8),SAH group (n=10),insulin group (n=10) and insulin+Edaravone group(n=12).SAH models were made by injecting blood twice into cisterna magna.30 min later of the first blood injected,the insulin 0.2 U/kg was subcutaneous injected in insulin group and insulin+Edaravone group,3 times daily for 7 d;while,the insulin+Edaravone group received Edaravone 0.5 mg/kg (intravenous injected in ear vein) twice a day for 7 d.7 d after the model made,the basilar artery cross sectional area was measured and the pathological changes were obseved to estimate the degree of CVS.The expression of insulin receptor(InRa) in vascular endothelial cell was detected by immunohistochemical staining.Results The basilar artery cross sectional area between insulin+Edaravone group[(0.46?0.3)mm2]and the sham-operated group[(0.48?0.4)mm2] was no significant difference;but they were obviously bigger than those in SAH group[(0.25?0.3) mm2] and the insulin group [(0.30?0.3)mm2](all P

Objective To explore the dynamic expression of ROCK-Ⅰ,p-MBS Thr-697,α-SMA protein and their mRNA in the hepatic fibrogenesis and the changes of actin cytoskeleton.Methods ROCK-Ⅰ and p-MBS Thr-697 protein in liver were determined by Western blot and their mRNA was examined by reverse transcription-polymerase chain reaction (RT-PCR),while the distribution of ROCK-Ⅰ and α-SMA in liver was assessed immunohistochemis-tically.The change of actin cytoskeleton was shown by fluorescence.Results With the development of hepatic fi-brosis,the positive areas in model groups at week 1 to 4 of ROCK-Ⅰ and α-SMA of the rat livers were larger than that in control group respectively(P <0.05).ROCK-Ⅰ,p-MBS Thr-697 ,α-SMA protein and mRNA were increased than that in control group respectively.ROCK-Ⅰ mRNA expression correlated with α-SMA (r =0.718,P <0.05).With the development of liver fibrosis,the images of fluorescence were inhanced.Conclusion With the develop-ment of liver fibrosis,both protein and mRNA of ROCK-Ⅰ increased.

Objective To compare the clinic significance of four clinical scoring systems in evaluating prognosis of acute pancreatitis: bedside index for severity in acute pancreatitis(BISAP), acute physiology and chronic health evaluation (APACHEⅡ), Ranson’s scoring system, computed tomography severity index (CTSI) in AP. Methods Patients visited our clinic with AP (n=114) in recent 2 years were retrospectively analyzed. BISAP and APACHEⅡscores were obtained at 24 hours after admission; Ranson ’s score was obtained at 48 hours after admission and CTSI are obtained was obtained at 72 hours after admission. Results of four scoring system were compared under different causes and different severity of the dis?ease. Correlation between BISAP score and the other three scores were analyzed and the predicative value of all four scoring systems for severity of AP and death were also compared. Results The mean values of four scoring systems show no signifi?cant difference in AP patients with different etiology (P>0.05). The BISAP score is positively correlated with APACHE-Ⅱ, Ranson ’s score and CTSI score (P<0.01). The four scoring systems all present good predictive value on the severity of AP and death (P<0.01). Conclusion The four scoring systems can all be applied to grading and prognosis for AP of various causes. BISAP is a simple, prompt, economical scoring system in clinical practice.

Objective:? N oxalo L ?,? diaminopropionic acid were isolated from the powder of red ginseng. its physiological characteristics were studied. Method:This material is obtained by CM Sephadex C 25 and FPLC MonoQ. We have examined the effect of ? N oxalo L ?,? diaminopropionic acid on contraction of artery of guinea pig. Result:When histamin and adrenalin do not exist, there is neither contraction nor relaxation. It can strengthen induction of contraction of artery of guinea pig, but it has no such effect on adrenalin. Besides, it doesn't induce plaque coagulation through adrenalin, ADP blood coagulation enzyme and collagen. It doesn't suppress the transformation from tension peptide of blood vessel to enzyme.Conclusion:Hemostatic effect of ? N oxalo L ?,? dlaminopropinomie acid may caused by vesseles contraction through promoting Histamine.

Objective To analyze the diagnostic value of fluorescence polarization assay (FPA) for human brucellosis.Methods From April 2013 to August 2014,240 positive sera of brucella patients were collected as case group and 287 normal sera as control group in Heilongjiang Agricultural Reclamation Bureau General Hospital.Four milliliters of venous blood were withdrawn for separation of serum.Fluorescence polarization assay was used and the consistency,sensitivity and specificity were compared with those of four classical serological methods,including rose bengal plate agglutination test (RBPT),standard tube agglutination test (SAT),Coomb's test and cysteine test.Results The results of FPA were complied with those of the four conventional serological methods,Kappa ≥ 0.75.The sensitivity of FPA (89.17％) was higher than that of RBPT (87.08％),SAT (85.00％),Coomb's (74.17％) and cysteine test (75.83％).The specificity of FPA (94.08％) was higher than that of RBPT (89.90％) and Coomb's (81.53％),but lower than that of SAT (98.95％) and cysteine test (99.30％).Conclusion FPA can be used as a laboratory diagnostic method for human brucellosis,which is worthy to be widely used.
