The hemolysin production of 19 strains of Streptococcus spp. isolated from pigs in the Jiangsu and Shanghai regions in recent years were examined. Eight isolates of Streptococcus suis type 2 from Jiangsu showed weak hemolysis on blood agar, but a stronger reaction in Todd-Hewitt broth(THB). The hemolysin belonged to the group of thiol-activated hemolysins. Nine strains of Streptoccus equi subsp. zooepidemicus showed strong hemolysis on blood agar and in THB containing 5% new-born calf serum, but no hemolysis in THB alone. This hemolysin was similar to streptolysin S(SLS). Another two isolates were atypical members of Lancefield group C Streptococcus and showed strong hemolysis on blood agar and in THB with 5% new-born calf serum, but the hemolysin was unlike either streptolysin O or SLS.

Panax ginseng C. A. Meyer (P. ginseng) has been used as traditional medicine in Asian countries for more than 2,000 years. P. ginseng contains many active components such as ginsenosides, peptides, essential oil and polysaccharides, among which, P. ginseng polysaccharides were reported to have immunomodulating, anti-cancer, anti-adhesive and antioxidant activities. For better understanding of the structures and biological activities of all the ginseng polysaccharides, here the recent research achievements were reviewed. This review would be helpful for the relevant researchers to get useful information.

Objective To analyze the causes of death and prognostic indicators of rheumatoid arthritis (RA).Methods A retrospective investigation was performed on 91 RA patients who were admitted into our hospital from 1990 to 2011.The clinical features and laboratory data were studied to assess the causes of death and the relationship between causes of death and disease activity and treatment.T test and x2 test were used for statistical analysis.Prognostic indicators of mortality were studied by Cox propor-tional hazards models.The prognostic indicators of RA were also analyzed.Results The three most common causes of death in patients with RA were infection (57%),cardiac-cerebral vascular diseases (13%) and cancer (12%).Severe disease activity and presence of extra-articular manifestations were more common among the patients who died.Seventy-five percent patients presented with systemic symptoms including fever,fatigue and weight loss,followed by pulmonary fibrosis (32%) and pleural effusion (27%).Cox regression analysis revealed that the presence of extra-articular features was independent risk determinant for mortality while DMARDs treatment was the independent protect determinant.Conclusion Infection,cardiac-cerebral vascular diseases and cancer are the main causes of death in RA.The presence of extra-articular features is the independent risk factor of RA.
