Journal of Clinical Neurology 1992;0(01):-
Objective To investigate the clinical manifestation, pathological features and pathogenesis of Holmes-Adie syndrome (HAS). Methods The clinical data of one HAS patient with sweating abnormality and combined with literatures were analysed. Results The patient had the typical characteristics of HAS, including Adie pupil, areflexia of lower limb and the symptoms of autonomic nerve dysfunction. The characteristic pupil of HAS was proved by slit lamp of ophthalmology. Cranial MRI showed lacunar infarction. A partial or total loss of neurons of the ciliary ganglion was the main pathological characteristic of HAS. Conclusions The etiology of HAS remains unclear, and has characteristic pupil finding, which was associated with autonomic nerve dysfunction to a certain extent. HAS still need to differentiate from Ross syndrome and Harlequin syndrome.

Ebosin is a novel exopolysaccharide produced by Streptomyces sp.139 with remarkable activity against rheumatic arthritis in vivo. In this paper, we reported effects of Ebosin on the inflammatory cytokines including interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFalpha) in THP-1 cells. With the special fluorogenic peptide as substrates, the enzymatic activities of interleukin-1beta converting enzyme (ICE) and TNFalpha-converting enzyme (TACE) were inhibited by Ebosin separately. Using the real-time reverse transcription polymerase chain reaction (real-time PCR), the mRNA synthesis of the three cytokines were identified decline separately by Ebosin. The secretion quantum of three cytokines in THP-1 cells with Ebosin was lower than that of normal THP-1 cells determined by ELISA assay and Western blotting. All of these results showed that Ebosin has remarkably suppressed synthesis of the three cytokines in THP-1 cells through different pathways. The primary study of Ebosin on anti-inflammation mechanism was promoted developing the new drugs treating rheumatic arthritis.

Objective To assess the effectiveness of balloon dilation and airway stenting performed under fluoroscopic guidance for the treatment of benign and malignant tracheal stenosis. Methods Under fluoroscopic guidance,balloon dilation and airway stenting were performed in 45 patients with tracheobronchial stricture. Of the 45 patients, malignant tracheal stenosis was seen in 37, including mediastinal nodal metastases (n = 14), esophageal carcinoma (n=13), lung carcinoma (n = 4), adenocarcinoma of bronchus (n = 3), lymphoma (n = 2) and laryngocarcinoma (n = 1), and benign tracheal stenosis was seen in 8, including endobronchial tuberculosis (n = 6), retrosternal thyroid adenoma (n = 1) and endotracheal intubation (n = 1). Airway stenting with serf-expandable metal stent was employed in 38 patients and balloon dilation in 7 patients. All the procedures were performed under fluoroscopic guidance. Results A total of 53 self-expandable metal stents was implanted in 38 patients. The clinical symptoms were immediately relived after the procedure in all patients except for one patient who died from choking of sputum. No stent migration was observed. Restenosis developed in 4 patients, which was successfully treated with repeated stenting and balloon dilation. Nineteen times of balloon dilation procedure were accomplished in 7 patients. Marked remission of clinical symptoms was seen in most cases. During a follow-up period (ranged from 0 to 124 months with a mean of 24.5 months) 31 patients died. Conclusion For both benign and malignant tracheal stenosis, balloon dilation with airway stenting performed under fluoroscopic guidance is a safe and efficient therapy with instant curative effect in relieving clinical symptoms.
