Objective To discuss digital subtraction angiography(DSA)findings and interventional treatment of broncho-costoarterial pulmonary circulation fistula(BPF).Methods Fifty one patients with massive hemoptysis were undergone DSA showing 19 cases with BPF.All BPF were cmbolized with 500～700?PVA, silk particles and segments,and steel coil;separately or in combination according to shunt orifice size and blood flow velocity.Results There were 4 types of BPF demonstrated by DSA according to feeding and drainage vessels,including 13 cases of bronchial artery-pulmonary artery shunt(AAS),2 cases of bronchial artery-pulmonary venous shunt(AVS),3 cases of intercostal artery-pulmonary artery shunt(IAPS)and 1 case of bronchial arteriovenous malformatoin(B-AVM).All patients were followed up for 1～4 years,with 18 cases of complete symptomless during 7 days postoperatively obtaining,the effective rate of 94.7%.There were 3 recurrent cases within 1 year with the recurrent rate of 15.79%.Conlusions BPF is the main factor for inducing and aggrevating pulmonary hemoptysis and interventional embolization serves as a safe and effective treatment.The method could be used repeatedly for recurrent cases and furthermore emphasis should be put on treating the primary pulmonary diseases simultaneously.(J Intervent Radiol,2007,16:84-87)

Objective To explore the polysomnography(PSG) characteristice of obstructive sleep apnea hypopnea syndrome(OS-AHS) and primary snoring(PS) in children and clinical value of PSG in children with sleep disorders. Methods We analyzed 74 children with OSAHS and 62 with PS, every patient being monitored with PSG for 7 hours at night for 16 parameters, including apnea hypopnea index(AHI), periodic leg movement index(PLMI),and the lowest oxygen saturation(LSaQ2) etc. The parameters of the 2 groups were comparaed. Results Comparaed with PS group, there was statistically significant difference in parameters such as PLMI, AHI,LSaQ2,the moderate oxygen saturation(MSaO2).AHI in non- rapid eye movement (NREM)(P

· AIM: To investigate the influence of TGF-β 2 antisense oligonucleotide(ASON) on the differentiation, proliferation of stromal fibroblast in corneal stroma injury.both eyes of 28 rabbits, the right eyes were served as experimental group, corneal incisions were sutured with 8-0 coated vicryl suture carrying TGF-β 2 ASON; the left eyes were served as control group, corneal incision were sutured with common 8-0 coated vicryl suture. Rabbits were killed at 4, 7, 14 and 28d after surgery, stromal fibroblasts were examined by immune histochemistry and electron microscopy.significantly reduced the numbers of cells expressingα -smooth muscle actin (α -SMA) and proliferating cell nuclear antigen (PCNA). The ultrastructure of fibroblast had no significant difference in two groups.differentiation and proliferation of stromal fibroblast in corneal injury. This will be a new method to adjust corneal wound repair.

Objective To evaluate the clinical impact of 18F-FDG PET/CT on patients with suspected cervical cancer recurrence. Methods Fifty-one cervical cancer patients, clinically suspected to have tumor recurrence during follow-up, underwent 18F-FDG PET/CT examination. 18 F-FDG PET/CT results were compared with those of conventional images, as referred to histopathology or clinical follow-up. Impacts of 18F-FDG PET/CT were evaluated based on documented changes of clinical management. Results In total, 43 patients were found to have positive lesions by 18F-FDG PET/CT, in which 40 were true recurrence,but 2 were pelvic abscess and 1 was radiation enterocolitis. Other 8 patients were found negative by 18F-FDG PET/CT and confirmed by pathology or follow-up. In patient-based analyses, the sensitivity, specificity, and accuracy of 18F-FDG PET/CT for the detection of tumor recurrence were 100% (40/40), 72. 73% (8/11),and 94.12% (48/51) respectively. In 7 patients, the clinical management was changed due to 18F-FDG PET/CT findings. Conclusion 18F-FDG PET/CT is an efficient tool for determining the recurrence of cervical cancer and instructing the clinical management.

Hippophae rhamnoides is one of the most representative economy crops for its wide uses of biological diversity and abundance of resource. As the key healthy food development and ecology protection, H. rhamnoides has been developed widely. Meanwhile, the development of H. rhamnoides has obtained great achievements. Nowadays, H. rhamnoides is still a necessary economy crop, while it has great influence on ecology protection. This paper discussed the phytochemistry, pharmacology, clinical application and product development, and propounded some suggestions for future research and economy development to get comprehensive benefit of H. rhamnoides and to serve for well-off society.

Objective To investigate the effects of iodine excess on mitochondrial superoxide production and mitoehondrial membrane potential(△ψ)changes in Fisher rat thyroid cell line(FRTL)cells.Methods FRTL cells were treated with 10-4mol/L potassium iodine(KI),10 U/L thyrotropin(TSH),10-4 mol/L KI+10 U/L TSH respectively for 24 h.Effects on cell proliferation were assayed by methyl thiazolyl tetrazolium(MTT)colorimetric method.Changes of mitochondrial superoxide production and △ψ were measured by live cell imaging and spectrofluorometer using MitoSOX and rhodamine 123(rh123)respectively.Results Absorbance(A)in the KI group (0.794±0.144)showed a significant decline compared to the control group(1.000 ±0.183,P<0.05),whereas a significant elevation was observed in the TSH group(1.215±0.156,P<0.05).No significant differences was found between the KI+TSH group(1.025±0.254)and the control group(P>0.05),but the former was marked higher than the KI group(P<0.05).Compared to the control group(9.74±3.24).MitoSOX mean fluorescence intensity (MFI)in the KI and KI+TSH groups(18.16±6.57,13.33±2.92)were significantly increased(all P<0.05),which was a significant decline in the TSH group(6.64±2.15,P<0.05).MitoSOX MFI in the KI+TSH group was lower than the KI group(P<0.05).Rh123 MFI in the KI and KI+TSH groups(210 593±31 328,295 525±34 243)showed significant decline than the control group(407 824±37 198,all P<0.05).Compared with the KI group.the KI+TSH group pronouncedly attenuated the reduction of Rh 123 MFI(P<0.05).No significant differences of Rh 123 MFI were found between the TSH group(411 187 ± 72 852) and the control group(P > 0.05). Conclusion Iodine excess (10-4 mol/L KI) may lead to peroxide damage on the mitochondria of FRTL cells, and cell proliferation is inhibited. Combining treatment with 10 U/L TSH may attenuate mitochondrial peroxide damage and inhibition of cell proliferation caused by iodine excess.

Objective To investigate the spatial distribution and clustering areas of Budd-Chiari syndrome in Heze City,Shandong Province,and to provide epidemiological information for further exploring the etiology and related risk factors of the disease.Methods Detailed residential addresses of 342 cases of patients (residents of Heze City) with diaphragm type Budd-Chiari syndrome diagnosed between 1995 and 2004 in Heze Municipal Hospital,Heze Shan County Central Hospital,Affiliated Hospital of Xuzhou Medical College,Shandong Provincial Hospital and Beijing Xuanwu Hospital were collected.Geographic information system (GIS) was used as a platform for data management and display.The nearest neighbor index,Ripley's K(d) function,Ripley's L(d) function and the nearest neighbor clustering method were applied to detect the spatial characters of Budd-Chiari syndrome in Heze City,Shandong Province.Crimestat 3.0 was used for spatial analysis.Results The nearest neighbor distance analysis showed that the nearest neighbor index was 0.6767 (Z =-11.4387,P ＜ 0.01).That was an aggregation at the first-order spatial scale.Within the study area,the first clustering radius of Budd-Chiari syndrome was 6.66 km,and the first clustering strength was 5.40; the average radius of the strongest clustering area was 126.61 km,and the clustering strength was 12.52,while the biggest clustering radius was larger than 222 km.After corrected by population,the gathering strength was slightly higher than that before the correction.Ten first-order hot spots were formed,and 95％ confidence interval aggregation number was 7,which meant the results were statistically significant(P ＜ 0.05),main clustering areas are in Mudan District,Shan County and Juancheng.One secondorder hot spot was gathered based on the first-order hot spot.Conclusions Spatial distribution of Budd-Chiari syndrome in Heze City,Shandong Province has showed spatial aggregation and heterogeneity.This study has a great epidemiological significance for further exploring the cause of Budd-Chiari syndrome.
