ABSTRACT

Objective To observe the effects of hedysari polysaccharide (HPS) on myocardial fibrosis and the expression of MMP-2/TIMP-2 in model mice of diabetic cardiomyopathy; To discuss the mechanism of action of prevention and treatment of myocardial fibrosis in diabetes.Methods Sixty mice were randomly divided into model group, rosiglitazone group and HPS high-, mediume- and low-dose groups. The normal group was 12 non-transgenic male BKS.Cg-Dock7m+/+Leprdb/JNjumice with the same age. Each group was given relevant medicine for gavage, for 8 weeks. Blood glucose of mice before and after medication 2, 4, 6, and 8 weeks was detected. The levels of MMP-2, MMP-2 and MMP-9 in myocardium were measured by Masson staining. The protein expressions of MMP-2 and TIMP-1 in myocardium were detected by Western blot.Results Compared with the model group, the blood glucose of HPS (high- and medium dose) groups and rosiglitazone group decreased significantly. Masson staining showed that the green fibers in the model group significantly increased and rosiglitazone group and HPS high-dose group decreased compared with the model group. Western blot showed that the expressions of MMP-2 in model group and MMP-2/TIMP-2 ratio were declined significantly, while the expression of MMP-2 was increased and TIMP-2 was decreased significantly, and the ratio of MMP-2/TIMP-2 increased in rosiglitazone group and HPS high- and medium-dose group.Conclusion HPS may reduce the degree of myocardial fibrosis in model mice with diabetic cardiomyopathy. The therapeutic effect of HPS may be to relieve myocardial fibrosis in model mice by increasing the ratio of MMP-2/TIMP-2.

ABSTRACT

Objective To analyze the epidemiological and clinical characteristics of 5 patients with importing yellow fever ,and to explore the preventive and control strategies of infection in hospital .Methods The epidemiological and clinical characteristics of 5 cases of importing yellow fever in Infectious Disease Hospital of Fujian Medical University from March 18th to April 6th in 2016 were retrospectively reviewed and analyzed .Results Five patients were all from Angola Luanda .One of them was vaccinated before going aboard ,and the others were vaccinated 1—10 days before disease onset in Angola .All of them were bitten by mosquitoes ,and their onset date ranged from March 11th to March 27th ,before returned to Fujian .The main clinical symptoms were fever ,chilly ,shivering ,fatigue ,arthrodynia ,headache ,and liver and kidney injury .At manifestations ,two patients had positive nuclear acid of yellow fever virus in serum samples and 3 patients were positive in urine samples .All of these patients were negative for dengue virus and Zika virus testing ,meanwhile no plasmodium was found in blood smears .All patients were cured and discharged . Conclusions There is risk of yellow fever transmission in Fujian Province . Prevention and control of the disease should be focus on improving the ability of finding and coping with the importing cases .Vaccination and hygiene knowledge propagation should be given for those who are going to epidemic country/area .Emergency monitoring and control of mosquitoes are necessary .
