Oligodeoxynucleotides containing CpG motifs have shown powerful immunoregulation effects, which are able to activate a variety of immune cells such as natural killer (NK) cells, monocytes,macrophages, dendritic cells(DC), B and T lymphocytes. CpG oligodeoxynucleotides (CpG ODN) can not only induce and enhance nonspecific and specific immune responses, but also regulate the type of immune responses through inducing Th1-type immune response and suppressing Th2-type immune response. DC are known to be the most powerful special antigen-presenting cells (APC) at present. It plays an important role in antigen recognition,antigen processing presenting, and T cell activation, and can kill various kinds of tumor cells. Recently, the immunotherapy based on tumor vaccines of dendritic cell has become more and more important. The research progress on dendritic cells for cancer treatment is reviewed in this article.

OBJECTIVETo explore the expression patterns of the chemokine CXCL12 and its receptor CXCR4 in human sperm.
METHODSWe collected semen samples from 10 fertile men, performed density gradient centrifugation, and then determined the expressions of both CXCL12 and CXCR4 in the sperm by RT-PCR and immunofluorescence staining.
RESULTSRT-PCR revealed the mRNA expressions of CXCL12 (0.641 +/- 0.180) and CXCR4 (0.464 +/- 0.100) in the sperm. However, only CXCR4 rather than CXCL12 was expressed at the protein level, and the positive staining for CXCR4 was observed mainly in the posterior part of the acrosome.
CONCLUSIONCXCL12 and CXCR4 are involved as important molecules in regulating the function of human sperm.

Objective To analyze the detection rate of lung cancer during 2009-2013 in Shaoxing of Zhejiang province and its time trend. Methods The data of lung cancer in Shaoxing from 2009 to 2013 with a total coverage population of 21 970 825 person-year (male 10 993 657 person-year, female 10 977 168 person-year), was collected to calculate the detection rate, age adjusted detection rate, percentage change of incidence (PC), etc. The annual percentage change (APC) of incidence was estimated by linear regression based on the logarithm of the incidence rates observed. Results During 2009-2013, a total of 9 973 new cases were diagnosed as lung cancer with the sex ratio of male to female being 2.44∶1. The detection rate of lung cancer was 45.39/100 000 (male 64.35/100 000, female 26.41/100 000), age-standardized detection rate by Chinese standard population (ASR China) was 20.09/100 000 (male 28.37/100 000, female 11.66/100 000), age-standardized detection rate by world standard population (ASR world) was 27.26/100 000 (male 37.83/100 000, female 15.73/100 000). The cumulative rate and truncated rate of those aged 0-74 and 35-64 were 3.40% (male 4.80%, female 1.91%) and 39.90/100 000 (male 54.44/100 000, female 24.81/100 000). The detection rate of lung cancer increased from 34.29/100 000 in 2009 to 59.91/100 000 (APC=13.88%, P=0.006<0.05), among males the detection rate increased from 50.60/100 000 to 82.91/100 000 (APC=12.52%, P=0.011<0.05), and the female detection rate increased from 17.81/100 000 to 36.78/100 000 (APC=17.70%, P=0.005<0.05). In Shaoxing, the detection rate of lung cancer increased obviously among the residents over 45 years of age. For each age group except 15-and 20-, the male detection rate was higher than the female incidence. Conclusion The men who were 45 years and older were at a higher risk of lung cancer in Shaoxing. The detection rate of lung cancer increased year by year from 2009 to 2013 in Shaoxing, especially among women over 65 years of age.

Objective:To determine the distribution of T-lymphocyte subpopulations in peripheral blood and its relationship with disease-free survival (DFS) of patients with different molecular subtypes of invasive breast cancer (IBC). Methods:Data and plasma samples of 372 female patients with IBC treated at Tianjin Medical University Cancer Hospital and Institute between January 2008 and August 2009 were obtained. CD4+/CD8+ratio and the amount of regulatory T cells (Treg cells) and natural killer cells (NK cells) were measured through flow cytometry. Results:A total of 133 (35.8%), 124 (33.3%), 48 (12.9%), and 67 cases (18.0%) presented luminal type A, luminal type B, HER-2 over-expression, and triple-negative type breast cancer (TNBC), respectively. In TNBC, a longer DFS was observed when the peripheral CD4+/CD8+ratio was high or when the level of Treg cells was low (CD4+/CD8+P<0.05 and Treg P<0.05). However, CD4+/CD8+and Treg are not independent prognostic factors for the DFS of TNBC cases. In other molecular subtypes of breast cancer, CD4+/CD8+ratio and the amount of Treg cells are not correlated with DFS (P>0.05). The level of NK cells is unrelated to the DFS of breast cancer with the four molecular subtypes (P>0.05). Conclusion:CD4+/CD8+ratio and the amount of Treg cells in peripheral blood may predict DFS of TNBC but are not considered as independent prognostic factors.

At present,diagnostic programs of food allergy in children mainly include medical history,skin prick test,detection of serum specific immunoglobulin E (sIgE) antibody,food challenge test,and so on.Among them,skin prick test and detection of sIgE antibody are used as primary screening tests with high diagnostic sensitivity while low specificity.Additionally,double-blind placebo-controlled food challenge test is the gold standard for the diagnosis,but it is faced with a potential risk of causing systemic allergic reactions,resulting in its rare application in clinic.Moreover,basophil activation test,as an in vitro test for allergen diagnosis,has significant value in diagnosis of food allergy in children due to its high specificity and safety.Besides,basophil activation test can also be used to evaluate the severity of food allergy in children,monitor immune therapy,detect trace allergens,and so on.
