Objective To investigate the prevalence and clinical characteristics of Sj?gren′s syndrome-interstitial lung disease (SS-ILD). Methods 136 patients with SS were studied. Anti-SSA and Anti-SSB antibodies were measured by Western blot. The inpatients had chest X ray, chest HRCT and pulmonary function examined. Results ①pSS-ILD patients with postive anti-SSA antibody were proned to have interstitial lung disease and the ILD were more severe. ②HRCT showed that sSS-ILD were more severe than that of pSS-ILD. ③Lung capacity of pSS-ILD decreased more frequently than sSS-ILD. sSS-ILD mainly had venti-latory function abnormalities. The lung function impairment of both were dominated by small airways dysfunction and decrease of TLCO. Conclusion SS patients should be examined by HRCT and lung function tests should be performed in the course of the disease to find out and treat ILD.

The microinjection of brain nuclei and potassium iontophresis induced tail flick were used to investigate the effect of injecting oxytocin (OT) or anti-oxytocin serum (AOTS) into locus ceruleus (LC) on the pain threshold (PT) and morphine analgesia. The result showed that OT injection into LC could enhance PT, while ATOS injection could reduce PT. The OT injection could strengthen morphine analgesia, but AOTS injection could antagonize this action. These results suggest that the OT analgesia and OT-enhanced morphine analgesia were related with the locus ceruleus.
