ABSTRACT
Objective To analyze the characteristics of adverse events following immunization ( AEFI) with varicella attenuated live vaccine ( VarV) in Hebei province during 2012—2014, to evaluate the safety of VarV and to provide supportive evidences for planning chicken pox prevention and control strate-gies in Hebei province.Methods The AEFI data associated with VarV in Hebei province during 2012 to 2014 were collected from the national AEFI information management system and were analyzed by using the method of descriptive epidemiology.Results A total of 239 cases reported during 2012 to 2014 were col-lected from the national AEFI information management system, with a male to female ratio of 1.44 ∶1.The estimated incidence rate was 25.51 per 100 000 doses.One case was serious AEFI with an incidence rate of 0.11 per 100 000 doses.Most of the AEFI cases were children under 3 years old and identified in scattered inhibiting children and kindergarten kids.The main symptoms of common vaccine reactions were fever, local swelling and induration .The rare vaccine reactions were presented as anaphylactic rashes .Conclusion The reported incidence rate of VarV associated AEFI in Hebei province was less than expected.However, the estimated incidence rate of common vaccine reactions in Hebei province was higher than that showed on the Analysis on Surveillance Data of Post-marketing Immunization Safety for Varicella Attenuated Live Vac-cine in China, 2010—2012.Attentions to the AEFI after immunization with VarV should also be paid in fu-ture.
ABSTRACT
Objective To investigate the expression of p21ras and microvascular density (MVD) in pancreatic carcinoma and to identify their clinico-pathological significance. Methods Expressions of p21ras and MVD were immunohistochemically assessed in 48 cases of pancreatic carcinomas. Results The expression rate of p21ras in pancreatic carcinomas was 60.40%, the MVD was (22.207?5.815) and (18.053?5.502) respectively in the p21ras-positive group and p21ras-negative group (P
ABSTRACT
Objective To investigate the expression of p21ras and vascular endothelial growth factor (VEGF) in pancreatic carcinoma, and to elucidate its clinicopathological implication. Methods Expressions of p21ras and VEGF were immunohistochemically examined in 48 cases of pancreatic carcinomas. Results The expressions of p21ras and VEGF in pancreatic carcinomas were 60.40% and 64.58%, respectively, and they were significantly higher than those in adjacent tissues (P
ABSTRACT
Objective To study the expression of VEGF and microvascular density (MVD) in pancreatic carcinoma and their prognostic value. Methods The protein expression of VEGF and MVD were determined with immunohistochemistry in 48 cases of pancreatic ductal carcinomas, which were surgically resected and pathologically confirmed. Results In 64.6% of pancreatic carcinomas the expression of VEGF was positive, and it was significantly higher than that of normal pancreatic tissues (P
