Objective To investigate the clinical features of primary Sj(o)gren syndrome (pSS) with interstitial lung disease (pSS-ILD) so as to raise the clinical diagnosis Level. Methods The clinical data were collected from 58 patients with pSS,who were admitted from March 2006 to March 2009. The patients were divided into ILD group (27 cases) and non-ILD group (31 cases). Rheumatoid factor(RF),C-reactive protein (CRP), protein electrophoresis and complement C3, C4 in serum were measured by immunoturbidimetric methods. Antinuclear antibodies (ANA) and anti-ENA antibodies were measured by indirect immunofluorescence technique and western blot. CA125 was detected by enzyme-linked immunosorbent assay and erythrocyte sedimentation rate (ESR) was detected by WS method. Pulmonaly function tests and radiology examination were performed. Results Compared with those in non-ILD group,the percentages of dry mouth,dry eye, rampant caries and velcro crackles were significantly higher in ILD group,anti-SSA antibody, ESR,CRP, CA125 and title of γ-gloulin was significantly higher in ILD group. In ILD group,diffusion dysfunction was 18 cases (66.7%),restricted ventilation dysfunction was 14 cases (51.9%),blocked ventilation dysfunction was 6 cases (22.2%), incorporated ventilation dysfunction was 8 cases(29.6%), forced vital capacity, forced expiratory volume in one second, maximum midexpiratory flow, DLCO were significantly lower in ILD group than those in non-ILD group (P < 0.01). Moreover,high resolution computerized tomography (HRCT) was more sensitive than chest X-ray in the diagnosis of pSS-ILD.Conclusions The presence of pSS-ILD highly associates with the activity of pSS. Pulmonary diffusion ventilation function and HRCT play an important role in the diagnosis of pSS-ILD.

Objective To investigate the effects of estrogen receptor alpha (Erα) gene polymorphism on the efficacy of ursodeoxycholic acid (UDCA) in female primary biliary cirrhosis (PBC) treatment. Methods The polymorphism of Xba Ⅰ and Pvu Ⅱ sites in No. 1 Intron of Erαgene was detected by polymerase chain reaction-restriction fragment length polymorphism in 65 female patients with PBC. The patients were treated with UDCA tablets daily (13-15 mg·kg-1 · d- 1,divided for 3 times oral taking). The variations of patients' serum total bilirubin (Tbil), alanine aminotransferase (ALT), alkaline phosphatase (ALP), γ-glutamyle transpeptidase (GGT) were followed up totally for 24 months. Results Totally the complete follow-up data had been obtained in 60 patients. Four indicators of XX or PP type patients slowly declined till the end of follow-up point still had not reached the effective treatment standard. Four indicators of Xx type patients were also slowly declined, while the effective treatment standard was achieved till the end of follow-up. Four indicators of Pp/pp or xx type patients were rapid declined to the effective treatment standard. The effective rate of UDCA in PBC treatment was 75.0% (45/60). The distribution difference of Pvu Ⅱ between the UDCA treating effective group and the ineffective group in PP, Pp, pp types patients and XX、Xx、xx types patients was statistic significant (x2 = 12.13、 P = 0.003 and x2 = 9.95 、 P = 0.007 respectively). The distribution difference of Xba Ⅰ between the effective group and the ineffective group with UDCA treatment in XX, Xx and xx types patients was also significant (P <0.05). The effective rate of Pp, pp, Xx, xx types patients [82.61% (19/23)、80.65% (25/31) 、9/14、83. 33% (35/42) respectively] was higher than PP and XX types patients (1/6 and 1/4 respectively).Conclusion Erα gene polymorphism influenced the efficacy of ursodeoxycholic acid in treating primary biliary cirrhosis.
