Objective To investigate the effects of Gegenqinlian Decoction on the IL-1β level in the patients with chronic periodontitis.Methods Seventy patients with chronic periodontitis were divided into the observation group and control group,35 cases in each group.The control group was given the periodontal basic treatment.On the basis of the control group,the observation group was given Gegenqinlian Decoction.The probing depth,attachment level and bacterial plaque index level before and after treatment were compared between the two groups.The levels of IL-1β and IL-6 in serum and gingival crevicular fluid were measured before and after treatment in the two groups.Results The total effective rate in the observation group was 94.29%,which was significantly higher than 71.43% in the control group,the difference was statistically significant (χ2=6.437,P<0.05).After treatment,the probing depth,attachment level and bacterial plaque index in the two groups were significantly decreased (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).The levels of IL-1β and IL-6 in serum and gingival crevicular fluid after treatment in the two groups were decreased significantly (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).Conclusion Gegenqinlian decoction can significantly reduce the IL-1β level in the patients with chronic periodontitis,reduces inflammation reaction and improves the therapeutic effect.

We report a case of cushing's syndrome caused by ectopic adreocortical adenoma. The patient is a 37 years old woman, she was admitted to our hospital for " 2 years history of hypertension and weakness in both lower extremities for 2 months". Physical examination revealed: blood pressure 160/116 mmHg(1 mmHg＝0.133 kPa), body mass index 27.47 kg/m2, moon-face, increased fat in the neck and back, purple marks on abdominal skin, withⅡdegree edema of both lower extremities. Laboratory examination revealed that serum cortisol levels were elevated, loss of normal circadian rhythm, and serum adrenocorticotropic hormone (ACTH) was suppressed, the level of cortisol could not be suppressed in low dose desamethasone suppression test. Adrenal computed tomography ( CT) revealed a nodule in the right retroperitoneum, compression of the renal hilum, no bilateral adrenal adenoma and hyperplasia were found. This patient was diagnosed as corticotropin-independent Cushing's syndrome unequivocally. The clinical symptoms were relieved after successful laparoscopic retroperitoneum resection of the nodule. Pathological exam confirmed adrenocortical adenoma in ectopic adrenal tissue. Thus, we should consider the ectopic corticosteroid-secreting tumor in the context of corticotropin-independent Cushing's syndrome, especially when the imaging studies of adrenal revealed bilateral adrenal glands were normal or atrophic, which helped to make an appropriate strategy treatment.
