Objective To analyze the effect of salvia tetramethylpyrazine on hemorheology in patients with vertebrobasilar transient ischemia attack (VB-TIA). Methods 84 patients with VB-TIA were divided into observation group and control group, 42 cases in each group. They both received the treatment of Ginkgo-diyidamolum injection. The observation group were treated by salvia tetramethylpyrazine, and the control group were treated by compound Danshen injection. The therapeutic effect of the two groups and the changes of blood rheology were compared. Results The clinical remission rate of the observation group was significantly higher than that of the control group, and the time of onset and symptoms of the drug were shorter than those of the control group (P < 0.05). The blood flow velocity of vertebral basilar artery in the two groups were significantly higher than those in the observation group (P < 0.05). After treatment, the hemorheology of the two groups were significantly improved, the high shear viscosity and low shear viscosity, platelet aggregation rate, erythrocyte deformation index, erythrocyte aggregation index and blood haematocrit of observation group improved more obviously (P < 0.05). The incidence of adverse reactions in the two groups was not statistically significant. Conclusion Salvia tetramethylpyrazine could effectively shorten the drug onset time, improve the blood velocity of vertebrobasilar artery, recover blood rheology and stability on the condition of not increasing the adverse reactions, which has a positive effect on the clinical remission rate.

In March 2017, a severely burned male patient aged 36 years with hypovolemic shock was admitted to our hospital. The patient received large quantities of antibiotics and blood products and repeated skin graft after admission, and then he suffered wound errhysis and throat congestion. The patient was healthy before without family history of bleeding or thrombosis disease. Laboratory tests showed that prothrombin time and activated partial coagulation time were remarkably prolonged, blood coagulation factor Ⅴ activity was extremely low, and the result of qualitative test of coagulation factor inhibitor was positive. Acquired blood coagulation factor Ⅴ deficiency was diagnosed. After application of dexamethasone (5 mg, twice per day) and infusion of fresh frozen plasma, blood coagulation indicators of patients recovered in 4 days, the result of qualitative test of coagulation factor inhibitor was negative, and bleeding symptoms were improved.

Objective:To investigate the expression of autophagy related genes microtubule-associated protein 1 light 3 (LC3) and forkhead box protein 1 light 3 (FoxO1) in gastric cancer tissues and its significance. Methods:The expression of LC3 and FoxO1 protein were examined by immunohistochemical SP method in 29 gastric cancer tissues and adjacent cancer tissues, their relationship with some tumor pathological parameters was analyzed. Results:The positive rates of expression of LC3 and FoxO1 protein in gastric cancer tissues were significantly higher than those in adjacent cancer tissues (P<0.01) .The expression level of LC3 in gastric cancer tissues was significantly correlated with tumor differentiation,lymph node metastasis,clinical stage and depth of tumor invasion, while it had no correlation with gender, age, tumor location and size of gastric cancer. The expression level of FoxO1 in gastric cancer was significantly correlated with tumor differentiation,while it had no correlation with gender,age,tumor location,size of gastric cancer,lymph node metastasis,clinical stage and depth of tumor invasion.Conclusion:Expression level of autophagy related genes LC3 and FoxO1 increased in gastric cancer tissues, and both of them are correlated with tumor differentiation, moreover, a high expression of FoxO1 is an frequent event in early gastric cancer, which suggested that increased level of autophagy activity plays an important role in promoting the occurrence and development of gastric cancer.

The Spt-Ada-Gcn5-acetyltransferase (SAGA) is an ancillary transcription initiation complex which is highly conserved. The ADA1 (alteration/deficiency in activation 1, also called histone H2A functional interactor 1, HFI1) is a subunit in the core module of the SAGA protein complex. ADA1 plays an important role in plant growth and development as well as stress resistance. In this paper, we performed genome-wide identification of banana ADA1 gene family members based on banana genomic data, and analyzed the basic physicochemical properties, evolutionary relationships, selection pressure, promoter cis-acting elements, and its expression profiles under biotic and abiotic stresses. The results showed that there were 10, 6, and 7 family members in Musa acuminata, Musa balbisiana and Musa itinerans. The members were all unstable and hydrophilic proteins, and only contained the conservative SAGA-Tad1 domain. Both MaADA1 and MbADA1 have interactive relationship with Sgf11 (SAGA-associated factor 11) of core module in SAGA. Phylogenetic analysis revealed that banana ADA1 gene family members could be divided into 3 classes. The evolution of ADA1 gene family members was mostly influenced by purifying selection. There were large differences among the gene structure of banana ADA1 gene family members. ADA1 gene family members contained plenty of hormonal elements. MaADA1-1 may play a prominent role in the resistance of banana to cold stress, while MaADA1 may respond to the Panama disease of banana. In conclusion, this study suggested ADA1 gene family members are highly conserved in banana, and may respond to biotic and abiotic stress.
