Objective To explore the serum levels of cytokines in patients with depression and their correlations with sex,age,depression severity and anxiety severity.Methods After enrolling subjects into the corresponding patient group and control group,the same trained researcher should continue to collect general information of the enrolled subjects as well as the HAMA and HAMD scoring results collection and assessment;And the serum levels of interlukin-1β (IL-1β),interlukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were detected with the method of enzyme-linked Immuno-sorbent assay (ELISA) in two groups.Results ① The serum levels of IL-1β,IL-6 and TNF-α of depression group were significantly higher than these in control group (P＜0.05),which were ((5.45±3.60) pg/ml vs(2.63± 1.92) pg/ml,(5.09±3.74) pg/ml vs (3.83±2.71) pg/ml,(5.77±3.94) pg/ml vs (4.05±3.25) pg/ml) respectively.②There was no significant difference in serum levels of IL-1 β,IL-6 and TNF-α between male and female patients with depression (P＞0.05).③ No conspicuous differences were found between the young group and the middle-aged group in serum levels of IL-1β,IL-6,TNF-α (P＞0.05).④ Serum level of IL-6 in major depressive disorder group((6.24±4.68) pg/ml) was more higher than that in mild to moderate depression group((3.95± 1.97)pg/ml),and the difference was statistically significant (t=2.467,P＜0.05).⑤There was significant differences in serum level of IL-6 between two groups,which were depression patients with and without anxiety (separately(5.80±4.37) pg/ml vs(3.87±1.80) pg/ml) (t=2.397,P＜0.05).Conclusions ①There is a phenomenon of immune activation,and levels of blood cytokines are raised in patients with depression.②Age and gender have no impact on depression in the level of cytokines.③IL-6 may be an important biological index that reflected the severity of depression and anxiety.

Objectives To express the miracidial antigen from eggs of Schistosoma japonicum (Chinese mainland strain) (SjMP10), and investigate the role of the miracidial antigen during the hepatic granuloma formation of schistosomiasis. Methods A pair of specific primers was designed and synthesized according to the nucleotide sequence of the open reading frame of the miracidial antigen gene. The open reading frame of the miracidial antigen gene was amplified, digested by restrictive enzyme(BamHI, SalI), and cloned directly into the expression plasmid pGEX-4T-3 to construct the recombinant plasmid. The recombinant plasmids were transformed into E. coli BL21(DE3), and induced by IPTG to express the fusion protein of GST-SjMP10. The expressed fusion protein was purified by electric elution method, and its antigenicity was examined by Western blotting and lymphocyte proliferation test. Results The gene of miracidial antigen was cloned into the expression plasmid pGEX-4T-3. After induced by IPTG, the recombinant expressed a fusion protein of GST-SjMP10, with a molecular weight of 39 000 approximately. The purified fusion protein showed proper antigenicity that could be recognized by the sera of rabbits heavily infected by Schistosoma japonicum and could stimulate the proliferation of splenic lymphocytes of infected BALB/c mice. Conclusion The miracidial antigen from eggs of Schistosoma japonicum was expressed successfully.
