OBJECTIVE:To guide rational use of Heamocoagulase agkistrodon for injection,and to provide reference for phar-maceutical care. METHODS:Treatment methods and outcome of 9 cases of allergic shock induced by Heamocoagulase agkistrodon for injection were retrieved from CNKI and VIP database during 2009-2015,and then analyzed statistically,based on one case of allergic shock induced by Heamocoagulase agkistrodon for injection in the Affiliated Hospital of Zhunyi Medical College. RE-SULTS:10 pationts with allergic shock induced by Heamocoagulase agkistrodon for injection mainly used the drug for hemostasis before and after surgery,heavy menstrual bleeding,etc.,with dose of 1 or 2 U. Route of administration included intravenous injec-tion and intravenous dripping. Allergic shock often occurred within 30 min after medication. CONCLUSIONS:The use of Heamoco-agulase agkistrodon for injection in some patients belongs to off-label drug use,and route of administration is different from that stated in package inserts. Allergic shock induced by Heamocoagulase agkistrodon for injection occurs rapidly;the drug should be used strictly according to package inserts and authoritative literatures;emergency plan should be developed before medication in or-der to guarantee the safety of drug use.

Objective To observe the changes of peptide YY (PYY) and its receptors in rats with ulcerative colitis (UC) by detecting both the serum level of PYY and jejunum epithelial cells in UC rats. Methods Rats were randomly divided into UC group, diarrhea-irritable bowel syndrome (D-IBS) group and control group. We measured the serum level of PYY by radioimmunoassay and made radioligand analysis of two basic parameters reflecting the characteristics of PYY receptors: dissociation constant (Kd) and maximum binding capacity (Bmax). Results The serum level of PYY was higher in UC and D-IBS groups than in normal group (P<0.001), and it was higher in UC group than in D-IBS group (P<0.001). However, the values of Kd and Bmax in UC group did not differ significantly from those in D-IBS and normal groups (P>0.05). Conclusion The serum level of PYY in UC group was significantly higher than that in normal group and D-IBS group; therefore, we assume that the change of serum PYY level may be related to not only the symptom of diarrhea but also inflammation. Kd and Bmax in neither UC group nor D-IBS group were significantly different from those in normal group, which indicates that the symptom and inflammation in UC may have nothing to do with the changes of PYY receptors.

Bibenzyl is a type of active compounds abundant in Dendrobium. In the present study, we investigated the inhibitory effects of six bibenzyls isolated from Dendrobium species on vascular endothelial growth factor (VEGF)-induced tube formation in human umbilical vascular endothelial cells (HUVECs). All those bibenzyls inhibited VEGF-induced tube formation at 10 micromol x L(-1) except tristin, and of which moscatilin was found to have the strongest activity at the same concentration. The lowest effective concentration of moscatilin was 1 micromol x L(-1). Further results showed that moscatilin inhibited VEGF-induced capillary-like tube formation on HUVECs in a concentration-dependent manner. Western blotting results showed that moscatilin also inhibited VEGF-induced phosphorylation of VEGFR2 (Flk-1/KDR) and extracellular signal-regulated kinase 1/2 (ERK1/2). Further results showed that moscatilin inhibited VEGF-induced activation of c-Raf and MEK1/2, which are both upstream signals of ERK1/2. Taken together, results presented here demonstrated that moscatilin inhibited angiogenesis via blocking the activation of VEGFR2 (Flk-1/KDR) and c-Raf-MEK1/2-ERK1/2 signals.

Objective: To explore the protective roll of ifbroblast growth factor 21 (FGF21) in endoplasmic reticulum stress (ERS) induced rat's H9c2 cardiomyocyte apoptosis with its mechanism. Methods: pcDNA4 was used as gene vector, pcDNA4-FGF21 plasmid was constructed and transfected into rat's H9c2 myocardiocytes for 48 h. ERS model was established by 10 μM tunicamycin (TM) induction for 24 h. The experiment was conducted in 4 groups:①Control group,②TM group, the cells were treated by TM,③pcDNA4-FGF21+TM group,④pcDNA4+TM group. The expressions of FGF21, protein kinase R-like ER kinase (PERK) and c-Jun N-terminal kinases (JNK) mediated apoptosis pathway related protein were measured by Western blot analysis; cell survival rate was examined by CCK-8 method and apoptosis rate was detected by TUNEL technique. Results: pcDNA4-FGF21 vector was successfully constructed and overexpressed in H9c2 myocardiocytes. Compared with Control group, TM group and pcDNA4+TM group had up-regulated endogenous FGF21 expression, increased PERK and JNK mediated apoptosis pathway related protein expression; reduced cell survival rate and elevated apoptosis rate. Compared with TM group and pcDNA4+TM group, pcDNA4-FGF21+TM group had down-regulated PERK and JNK mediated apoptosis pathway related protein expression; increased cell survival rate and decreased apoptosis rate. Conclusion: FGF21 overexpression can reduce ERS induced apoptosis rat's H9c2 myocardiocytes which might be partly related for inhibiting PERK and JNK mediated signal transduction of apoptosis pathway.

Objective To study the therapeutic effects and mechanisms of Astragaloside-Ⅳ (ASG-Ⅳ) on diabetic cardiomyopathy (DCM) in the rat diabetic model. Methods Forty SD(Sprague-Dawley)healthy rats were used. The diabetic retinopathy rats model were induced by STZ, 45 mg/kg, 3d. Another 10 were injected the same amount of citrate buffer as a control group. Fasting blood glucose was measured with SureStep Plus detector 72 h later. The blood glucose of the diabetes model was ≥16.7 mmol/L. And 12 weeks later, DCM rats were divided into 4 groups randomly in the experiment, includes: DCM, ASG-Ⅳ-L (10 mg/kg), ASG-Ⅳ-M (30 mg/kg), ASG-Ⅳ-H (60 mg/kg)groups. After give dugs 4 weeks, the phosphokinase isoenzyme (CK-MB) and LDH level were tested, the cardiac hypertrophy was evaluated by HW/BW and LVW/BW. Activity of Na+-K+-ATPase and Ca2+-ATPase were determined in left ventricular tissues by ATPase ELISA Assay Kit. The content of FFA was measured and myocardial pathological examination was performed. Results Compared with the control group, blood and urine glucose were higher than experimental animal in diabetic model group, were significantly increased (P<0.05). LDH and Phosphokinase isoenzyme (CK-MB) level were significantly increased, the HWI and LVWI ratio were enhanced in DCM group (P<0.05). ASG-Ⅳ could reduce the ratio of HWI and LVWI, decrease the level of CK-MB and LDH, improve the pathomorphological changing of DCM rat model (P<0.05). Moreover, compared with DCM group, ASG-Ⅳ could restore the Na+-K+-ATPase and Ca2+-ATPase activity, reduced the content of FFA (P<0.05). Conclusion ASG-Ⅳ plays therapeutic effect on diabetic cardiomyopathy might via restore the Na+-K+-ATPase and Ca2+-ATPase activity, reduce the content of FFA, protect the myocardial energy metabolism in DCM.
