Objective To investigate the angiographic manifestation of the proper esophageal artery (PEA),the hish risk factom for the presence of the anomalous PEA in hemoptysis and to evaluate the safety of transcatheter aaefial embolization(TAE) of the PEA using gelatin sponge(GS).Methods Selective esophageal arteriography WSS performed in forty-three patients with hemoptysis,including 15 cases of pulmonary tuberculosis,18 cases of bmnchiectasis,7 cases of posttuberculous bronchiectasis and three cases of lung cancer. One case experienced failure of bronchial arterial embolization. The angiographic manifestation of the PEAs Was studied.The complications of the procedure and clinical results were observed in the patients who underwent TAE using GS.Results Thirty-nine PEAs were catheterized selectively in 37 patients(86.0%).Eighteen anomalous PEAs(46.2%)were catheterized selectively in 17 patients (45.9%).The anomalous PEAs showed tortuosity,dilatation,hyperplasia,shunting with pulmonary artery and anastomosis with the bronchial artery.All lesions involved basal segment of inferior pulmonary lobar. Bronchiectasis Was the most frequent disease for PEA abnormality. No complications occurred and satisfactory curative effect Was achieved with TAE of the anomalous PEAs.Conclusions It is necessary to perform selective proper esophageal arteriography when the lesion involves basal segment of inferior pulmonary lobar in hemoptysis.Supplemental TAE of the anomalous PEA using GS is safe and valuable in the management of hemoptysis.

Recombinant human BMP-2 was compounded with chitosan/gelatin/hydroxyapatite(HCG) scaffold and the complex was sterilized by 60Co radiating. Osteoblast isolated from cranial bones of newborn rat was primary cultured and seeded onto the complexes. 3 days after culturing, scanning electron microscope(SEM) was applied to detect the compatibility of the cell with the complex. SEM showed osteoblast attached closely with the complex and grew well in its pores. Then the complexes with osteoblast modification were implanted into athymic nude mice subcutaneously. 8 weeks after implantation, X-ray photograph and histological observation were applied to detect the bone formation of the complexes. Under X-ray a high-density areas consistent with the shape of the implanted complex could be seen. Histological observation also proved there was bone formation in the interspace of the complex. A conclusion was drawn that rhBMP-2 compounded HCG scaffold had good osteogenesis ability in vivo.

Objective To investigate the efficiency of radiofrequency ablation (RFA) and microwave ablation (MWA) in treating uterine leiomyoma.Methods The clinical data of thermal ablation with RFA and MWA were retrospectively analyzed in 42 patients.All patients were followed up at least 12 months to observe the therapeutic effects after the treatment.The changes of vital signs and the size of uterine leiomyoma,the score of uterine leiomyoma symptom and quality of Iife(UFS-QOL) were compared after RFA or MWA,the two thermal ablations techniques of clinic efficiency and influence on complications were analyzed.Results 23 patients received treatment of RFA and 19 patients received MWA,the visual analogue scale(VAS)during operation and postoperation were statistically significant differences between the two groups(P ＜0.05).The sizes of uterine leiomyoma were significantly reduced after the thermal ablation,the differences of volume within two groups in different time were statistics significance(P ＜0.05),but there were no statistics significance differences between two groups (P ＞0.05).The symptoms in two groups were improved significantly after treatment and the scores of UFS-QOL were no statistics significance differences between two groups (P ＞0.05).Conclusions Both of RFA and MWA have significant clinic efficiency in treating uterine leiomyoma.Compared with MWA,RFA with lower adverse reactions during operation and postoperation.

Objective To explore the CT findings of mucoepidermoid carcinoma (MEC) of the tracheobronchial tree and improve the diagnostic accuracy. Methods The CT images, histopathological and clinical data in 24 patients with pathologically proved MEC of the tracheobroncbial tree were retrospectively analyzed. Results The clinical symptoms included cough, sputum, fever, wheezing, chest pain and hemoptysis. The patient was proved to be low-grade (n=19) and high-grade (n=5) MEC histopathologically. One lesion was located in trachea, 6 in main bronchus, 12 in lobar bronchus and 5 in segmental, subsegmental and distal bronchus. The tumor presented as no-invasive endotracheobronchial well-defined round-like nodule (n=13, locating in lobar and higher bronchus) and columnar sharp (n=3, locating in main bronchus), or intra-and-extraluminal well-defined round-like nodule or mass (n=6, locating in lobar and lower bronchus) and irregular mass with invasive pattern (n=2, high-grade type). The density of lesion was similar to the muscule and the calcification within lesion was showed in 4 patients on non-enhanced CT. The lesion had marked enhancement in 17 patients on enhanced CT. Obstructive changes were found in 20 patients. Conclusion MEC of the tracheobronchial tree is usually low-grade malignancy and locates in main and lobar bronchus with no-invasive well-defined airway mass, marked enhancement and calcification on CT.

Objective To further understand the clinical manifestations and improve clinical diagnosis of patients with leptomeningeal metastasizing high-grade glioma.Methods Sixteen patients with leptomeningeal metastasizing high-grade glioma (WHO classification:grade Ⅲ-Ⅳ) in Department of Radiotherapy,the First Hospital of Jilin University from July 2010 to September 2015 were respectively analyzed.The pathological types included anaplastic gliomas (1),anaplastic oligodenastrocytoma (1),glioblastoma (12),small-cell glioblastoma (1),gliosarcoma (1).We reviewed the relative clinical manifestations of the patients,and further compared them with 163 patients with systemic malignant solid tumors at corresponding period.Results The median time from initial diagnosis to the diagnosis of leptomeningeal metastasis was 13.0 months (range 2-19 months).Plain and enhanced magnetic resonance imaging was obtained in all patients.The main radiographic characteristics included ependymal enhancement (11),leptomeningeal enhancement (3),nodules of implantation metastasis in spinal canal (1),cranial nerve enhancement (2),and ventricular dilatation (1).Eight patients received cerebrospinal fluid examination.The diagnosis of leptomeningeal metastasis in 15/16 patients was determined by radiographic findings.Comparing with leptomeningeal metastasis from systemic malignant tumors at the corresponding period,the incidence of headache in patients with high-grade glioma was significantly lower (6/16 vs 81.6％ (133/163);x2 =16.3,P ＜ 0.01);and the incidence of cranial nerve paralysis was also significantly lower (4/16 vs 56.4％ (92/163);x2 =5.79,P =0.016 1).The incidence of nerve root symptoms was lower than that of systemic malignant tumors,though without statistically significant difference (2/16 vs 26.4％ (43/163);x2 =1.49,P=0.222).Nine patients respectively received chemotherapy,intrathecal chemotherapy or intrathecal chemotherapy combined with whole brain radiotherapy.The median survival tine was 4.5 months (range 0.7-13.3 months).Conclusions The imaging examination played an important role in the diagnosis of high-grade leptomeningeal metastasizing glioma.Comparing with the systemic malignant solid tumors,the leptomeningeal metastasizing high-grade glioma had its unique clinical characteristics.
