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.

AIM: To investigate the preventive effects of Shengmai San (SMS) on oxidative damage in mentally stressed mice.METHODS: An oxidative stress mouse model was established by moustache-removed. Protein carbonyl and thiobarbituric acid reactive substance (TBARS) formation were determined as the oxidative stress markers.RESULTS: (1)Moustache-cut was founded to significantly enhance the behavioral movements of mice, especially large movements (movement 2 and rearing). SMS pre-administration inhibited the accelerated movements. (2) Protein carbonyl was increased in brain, heart, liver and kidney. TBARS in liver and heart increased in the moustache-cut mice, but SMS pretreatment inhibited the increased protein carbonyl and TBARS.CONCLUSION: SMS has the preventive effects on oxidative damage induced by emotional stress.

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.

This report presented a case of disseminated infection with nocardia in lupus erythematosus (SLE) and reviewed the current literature. Nocardiosis was a rare, sometimes life-threatening opportunistic infection in SLE patients. The isolation and identification of pathogen was fundamental for the diagnosis of nocardiosis. Sulfonamides were traditionally the agent of choice for treatment of nocardiosis; while it must be given for several months even more than one year, particularly in patients with suppressed immune function. Issues regarding the drug resistance and the toxicity of sulfonamides in long-term therapy needed to be considered. Linezolid could be an effective agent for the treatment of nocardiosis, whether it could reduce the treatment course need to be further studied.

Objective To evaluate the value of low-dose computed tomographic colonography (CTC) performed with 64-slice CT in the diagnosis of incidental extracolonic lesions and its clinical significance .Methods The image data in 158 CTC examinations with two positions were retrospectively analyzed .All abdominal extracolonic lesions were recorded .According to the age ,the pa-tients were divided into two groups :elderly and non-elderly groups .The extracolonic lesions were divided into 4 groups(E1- E4) according to the clinical importance .The incidence rates in two groups were calculated respectively .Results The incidence rate of the E2-E4 level extracolonic lesions in the elderly group was higher than that in the non -elderly group ,the difference between them had statistical signficance (P< 0 .05) .Conclusion Low-dose CTC has the high diagnostic value in finding extracolonic le-sions ,and the incidence rate of extracolonic lesions with important clinical significance is increased with the age increase ,especially for the elder patients over the age of 60 years .

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.
