Objective To study the imaging findings and patholoical characterizes of chondromyxoid fibroma in order to improve its differential diagnosis.Methods 8 cases with chondromyxoid fibroma had all proceeded x-ray checked before operation. Of these cases , 4 cases were examed by CT scan .All cases were confirmed by operation and pathology. The imaging findings and pathological characterizes were analysed.Results The lesions located at metaphysis of long bone and presented as a round or elliptic transparent area which were consistent with long axis of involved bone. There were osseous crests inside the lesions and sclerosis bone around the lesions. The density of lesions was homogeneous and CT numbers were about 26 HU. On histopathology,lesions presented grey. Lobular and some what transparent . In the center of lesions there were a lots of mucus and stellate cells. The lesions were surrounded by hyperplastic area including multinuclear giant cell and chondroblast fibroblast. Conclusion chondromyxoid fibroma has characterizes on imagiology and pathology , but it has often been misdiagnosed.

Objective To establish the HPLC fingerprint of Rosae Rugosae Flos;To provide references for the quality evaluation of Rosae Rugosae Flos.Methods The HPLC analysis was carried on a COSMOSIL 5C18-MS-Ⅱ column(4.6 mm×250 mm,5 μm);the mobile phase was 2.5 % acetonitrile + 0.1 % formic acid aqueous solution(A)-acetonitrile + 0.1 % formic acid(B)with gradient elution at the flow rate of 0.5 Ml/min;the column temperature was 40℃;the detection wavelength was 350 nm.The similarity of 13 batches of samples was evaluated by Similarity Evaluation System for Chromatographic Fingerprint of TCM(2012 edition).Qualitative analysis was carried out by LC-MS technology.The overall quality evaluation of Rosae Rugosae Flos was carried out by combining clustering analysis,principal component analysis and orthogonal partial least square discrimination.Results The common mode of HPLC fingerprints of Rosae Rugosae Flos was established,and the similarity of 13 samples was good.9 compounds were identified preliminary.13 batches of samples were aggregated into 3 categories by chemical pattern recognition.Conclusion The fingerprints of Rosae Rugosae Flos established in this study combines with chemical pattern recognition method,which has high sensitivity and strong specificity,can provide a basis for the quality evaluation of Rosae Rugosae Flos.

Objective:To investigate the efficacy and safety of endovascular recanalization in the treatment of chronically occluded internal carotid artery (COICA).Methods:From January 2014 to January 2019, patients over 50 years of age with symptomatic COICA underwent endovascular recanalization in the Department of Neurosurgery of the First Affiliated Hospital of Xinjiang Medical University were enrolled retrospectively. The modified Rankin Scale (mRS) was used to evaluate the improvement of neurological function.Results:A total of 19 patients with symptomatic COICA were enrolled, of which 16 (84.21%) were successfully recanalized. None of the patients had severe neurological deficits during the periprocedural period and after procedure. The neurological function of patients with successful recanalization gradually improved over time. The neurological function improved in 4 patients (25.0%) at 24 h after endovascular treatment and 9 (56.3%) at 18 months postprocedural follow-up. The follow-up of CT angiography showed that the internal carotid artery in patients with successful recanalization was unobstructed, and there was no obvious in-stent stenosis.Conclusion:Endovascular recanalization is feasible, safe and effective in patients with symptomatic COICA.
