Objectives To investigate the association between HLA-DQB1 alleles and Han Chinese with generalized pustular psoriasis (GPP) from Shandong. Methods The distributing frequencies of HLA-DQB1 alleles were detected with polymerase chain reaction-sequence specific primers (PCR-SSP) in 38 GPP patients and 94 healthy subjects from Shandong. Results ①The frequencies of HLA-DQB1*0201 and *0603 alleles increased significantly in GPP patients compared with those of the healthy controls(Pc = 0.005 and Pc = 0.013 , respectively), and the frequency of HLA- DQB1*0604 alleles decreased (OR = 0.08, Pc = 0.039). ②There were significant association between the GPP patients with a previous history of psoriasis vulgaris and HLA-DQB1*0201 and *0603 alleles (OR = 32.31, Pc = 0.005; OR = 12.42, Pc = 0.005, respectively), and between the GPP patients without the history and HLA-DQB1*0602 alleles (OR = 5.60, Pc = 0.039). Conclusions HLA-DQB1*0201 and *0603 alleles are significantly associated with the Chinese patients with GPP in Han population from Shandong. There is a significant heterogeneity in the GPP patients with and without the history of psoriasis vulgaris.

Objective To investigate the effect of total hip arthroplasty in treatment of patients with ankylosing spondylitis and bilateral hip bony ankylosis. Methods 43 patients with ankylosing spondylitis and bilateral hip bony ankylosis were randomly divided into observation group (23 cases) and control group (20 cases) in accordance with the principle of informed consent, individually treated by total hip arthroplasty and conservative treatment, the effect of two groups were compared and analyzed. Results In the observation group, the postoperative Harris hip score and the VAS pain score of patients were significantly better than the control group,the differences were all statistically significant between two groups( all P ＜ 0.05 ). Excellent rate of the two groups were 91.3% and 60.0% respectively, and the difference was statistically significant ( x2 = 4.328, P ＜ 0.05 ). Conclusion Total hip arthroplasty in treatment of patients with ankylosing spondylitis and bilateral hip bony ankylosis has better clinical effect, and could improve the quality of life of patients, so it was worthy of clinical application.
