The specific human immunoglobulin is a hyperimmune globulin against a particular pathogen or biotoxin .It′s an important variety in plasma derivatives .Specific human immunoglobulin is usually used to prevent and treat pathogen in -fections with high morbidity , severe outcomes and no efficient treatment available .Thus it has unique advantages in preven-tion and management of infectious diseases .A variety of specific human immunoglobulins have been licensed abroad , but the development of new specific human immunoglobulins is slow in China due to technical constraints , limited economic benefits or for other reasons .Here we reviewed some specific human immunoglobulins and their preventive and therapeutic effect on infectious diseases .

Objective To systematically evaluate the relationship between the intake of fruits and vegetables and the risk of prostate cancer, so as to provide relevant evidence for formulating the prevention strategies of prostate cancer. Methods Pubmed, Embase, and Web of Science databases were searched by computer for cohort studies and related literatures evaluating the relationship between vegetable and/or fruit intake and prostate cancer risk. The quality of the included literature was rated, and meta-analysis was carried out using R software (4.0. 3 version). Results A total of 20 cohort studies were included. Four studies only reported the relationship between fruit intake and the risk of prostate cancer, 4 studies only reported the relationship between vegetable intake and the risk of prostate cancer, and 12 studies reported the relationship between fruit and vegetable intake and the risk of prostate cancer. Meta-analysis results indicate that although dietary intake of vegetables in the high-intake group may reduce the risk of prostate cancer, the difference was not statistically significant (RR, 0.97; 95% CI (0.94, 1.01), P=0.11); I2=21.3%, P=0.21). There was no significant correlation between fruit intake and the risk of prostate cancer (RR, 1.00; 95% CI (0.96, 1.04) , P=0.99). Conclusion There is no significant correlation between the intake of vegetables and/or fruits and the risk of prostate cancer.
