Objective To analyze the clinical data of diagnosis and treatment of Wegener' s granulomatosis (WG) in order to understand the nature of this disease. Methods The clinical data including clinical manifestations,laboratory findings imaging features,pathological changes and efficacy of treatment of 34 patients with WG admitted from January 2002 to March 2012 were analyzed.Results Of the 34 patients,male to female ratio was 18 to 16,and the average age subjected to WG onset was (45 ± 15)years old ranged from 18 to 81 years old.The average duration before the diagnosis confirmed was ( 140 ±72) mouths,while 29.4% was diagnosed within 3 months. The presenting symptoms included initial involvements in lung (41.1%),nose (38.2% ),eyes ( 11.7% ),ear (8.8% ) and constitutional symptoms such as fever (26.4% ). Throughout the whole disease course,the incidence of systemic impairments were as follows:lung (76.4%),nose (73.5%),kidney (67.6),eyes (58.5%),ear (47.0%),nervous system (41.1%),oral ulcer (20.5% ).Of laboratory findings,C - ANCA/PR3 -ANCA was positive in 61.7% patients,P - ANCA/MPO - ANCA positive in 20.5% patients,ANCA negative in 11.7% patients,P- ANCA positive with MPO- ANCA negative in one patient (2.9 % ) and C -ANCA positive with PR3 and MPO positive in one patient (2.9% ).Of imaging findings,nodules or masses were most commonly observed (34%), followed by fibrotic lesions (20.5% ), cavitations ( 17.6% )、opacities ( 17.6% ).Typically pathological triad ( vasculitis,necross and granuloma formation)was found in one patient ( 4.3% ),while two pathological changes of the triad occurred in 10 patients (43.4%). Pulmonary infection was highly prevalent (50%), and of them,20.5% patients were misdiagnosed as tuberculosis,malignancy or abscess.After admission,high dose of corticosteroids and cyclophosphamide were administered as bolus and maintenance therapy. Plasma exchange,intravenous immunoglobulin,and rituximab were added for refractory cases and optimal response were obtained in most cases.Conclusions Wegeners granulomatosis is a clinically complicated entity and sometimes can have progression,leading to misdiagnosis. Early and prompt use of steroids and cyclophosphamide may confer good therapeutic efficacy and avoid life -threatening complications.

Objective: Using the COI Barcode to establish the standard method to identify the traditional Chinese medicine of deer products. Methods: In this study, DNA extraction, PCR amplification, and sequencing of experimen-tal samples (deer antler, penis and testis, tendon, tail, bone, foetus) were successful. COI sequence database were constructed and commercial crude drugs of deer were investigated and analyzed. Results: By using universal COI primer,PCR amplification is preferably. All the species could be identified based on COI sequences database of tra-ditional Chinese medicine of deer which contained 101 samples of 8 species. We have collected 40 commercial crude drugs in which 18 samples were identified as species described in Chinese pharmacopoeia. Conclusion: DNA barcode technology based on COI sequence could be a standard approach to identify traditional Chinese medicine of deer products, and provide the basis for the identification of commercial deer medicine.
