Objective To explore the potential association between HLA-DRB1 Alleles and systemic scleroderma (SSc) of the Zhuang Nationality in Guangxi region. Methods Polymerase chain reaction-special sequence primers (PCR-SSP) was used to study the HLA-DRB1 alleles in 58 patients with SSc and 50 healthy controls of the Zhuang Nationalty in Guangxi Province. Comparisons between groups were performed with χ2 test or exact probabilities. Results Sixteen HLA-DRB1 alleles were discovered from the specimens,including 14 in the SSc specimens, and 16 in the control specimens. Among them,the allele frequencies of HLA-DRB1 * 1301 (7.760%, OR=9.000, χ2=4.341, P=0.037), HLA-DRB1 * 1305 (11.207%, OR=3.322,χ2=4.206, P=0.040) and DRB1 * 15 (26.724%, OR=2.679, χ2=6.038, P=0.014) were significantly higher in SSc patients than those of the controls (respectively for 1.000%, 4.000%, 15.000%). Conclusion Our data suggest that the HLA-DRB1 * 1301, HLA-DRB1 * 1305 and HLA-DRB1 * 15 may be the susceptible genes of SSc in Zhuang nationality population.

Objective: To study the effect of ipilimumab on T lymphocytes and Bcl-2 mRNA expression in lung cancer-bearing mice by inhibiting TGF-β1/ERK signaling pathway. Methods: Forty-five C57 mices inoculated with Lewis lung cancer cells were randomly divided into control group, low dose ipilimumab group and high dose ipilimumab group with 15 mice in each. The low and high dose groups were given 3 mg/kg and 5 mg/kg ipilimumab respectively, while the control group was given 0.9% sodium chloride solution with the same volume. The effects of ipilimumab on TGF-β1/ERK signaling pathway, Bcl-2 mRNA expression, immune function improvement and tumor inhibition in three groups were detected by WB and qPCR. Results: After administration of ipilimumab, the tumor weight and volume of mice in low-dose and high-dose groups were significantly lower than that of the control group, and the tumor inhibition rate increased in a dose-dependent manner (P<0.05). The thymus index and spleen index of mice were significantly higher than that of control group, which also increased in a dose-dependent manner (P<0.05). The levels of CD3+, CD4+, CD4+/CD8+ cells in the high and low dose groups were significantly higher than those in the control group, with significantly higher levels in high dose group compared with the low dose group (P<0.05). The levels of serum inflammatory factors were significantly lower than those in control group, and the levels of serum TNF-α, IL-6 and IL-3 in the high dose group were significantly lower than those in the low dose group (P<0.05). The expressions of TGF-β1, ERK1/2, p-ERK1/2 and MEK in tumor tissues of both high and low dose groups significantly decreased, with more lower levels in high dose group than in low dose groups (all P<0.05), and the positive rate of TGF-β1 expression in high dose group was the lowest. The mRNAexpression of Bcl-2 in tumor tissues of high and low dose groups decreased significantly after drug administration, with a significantly lower level in high does group than that in low dose group (P<0.05). Conclusion: Ipilimumab can effectively inhibit TGF-β1/ERK signaling pathway, improve immune function and down-regulate the expression of Bcl-2, thus inhibit the growth of Lewis lung cancer cells and play an antitumor role in mice.
