Objective To evaluate the safety and efficacy of interventional procedure for treating the renal artery aneurysm (RAA).Methods From Jan 2009 to Apr 2014,17 patients,who were diagnosed as RAA and accepted the interventional therapy,were reviewed in our hospital.The mean age in those patients,including 7 males and 10 females,was (46.4±10.3) years old (range from 20 to 67 years old).The related symptoms included backache in 4 cases,abdominal pain in 4 cases,intermittent hematuria in 2 cases,chyluria in one case,oligouria in one case.9 cases were diagnosed as multiple RAA and 8 cases were confirmed as signle cases.In 17 cases,31 aneurysms were found,including 26 true aneurysms,5 pseudoaneurysums,17 sacculated aneurysms,4 spindle-like aneurysms,4 irregular shape aneurysms,4 parenchyma aneurysm and 2 dissecting aneurysm.8 aneurysms located in the main renal artery,19 aneurysms located in the branch of renal artery,4 aneurysums located in the renal parenchyma.Intracavitary coil embolization was used in 4 patients.We carried out parent artery embolization in 3 patients.A combination of the former techniques was performed in 6 cases.Covered stent placement was operated in one case.Combination of the intracavitary coil embolization and nude stent placement were performed in 2 patients.We used two techniques in one patient with multiple artery aneurysms in both sides.Results The interventional treatment of RAAs succeed at the first operation in 16 of 17 patients.17 cases were followed-up from 3 to 53 months (mean 23 months).No severe complications or death cases occurred in this study.Urine occult blood in 3 patients turned to negative after one week.Primary symptoms such as gross hematuria,abdominal pain,lumbodorsalgia,fever vanished or obviously eased after a month.Laboratory tests showed that normal level in SCr,BUN,routine urinalysis 3 months,6 months and 1 year later.No tendency of stent and coil stent shifting was found in 16 patients and the parent arteries were patent in 8 cases,with reexamination bv ultrasonic or computed tomography angiography (CTA).Conclusions Interventional techniques are minimally-invasive,safe and effective methods for treating the RAAs.

OBJECTlVE To study the effect of ganoderma poIysaccharide( GLP)on zebrafish ( Danio rerio)survivaI,deveIopment and senescence. METHODS A p53-knockout zebrafish modeI was estabIished by injecting of morphoIino phosphorodiamidate(mO)into normaI zebrafish eggs in the singIe ceII deveIopment stage. Different concentrations of GLP 1,2 and 3 g·L-1 were used to treat both wiId type and p53-knockout zebrafish embryos 8 h post fertiIization(8 hpf)under 28℃ for 3 d. The survivaI and maIformation rates were caIcuIated after 72 hpf,and the effect of GLP on ceII senescence was evaI-uated by senescence associated β-gaIactosidase(SA-β-gaI)staining both in wiId type and p53-knockout zebrafish embryos. In addition,the differentiaI gene expression of cancer inhibitor gene(p53),teIomer-ase reverse transcriptase( TERT),murine doubIe minute2( mdm2)and p21 was examined by RT-PCR both in wiId type and p53-knockout zebrafish embryos after treatment with different concentrations of GLP. RESULTS GLP 1 and 2 g·L-1 had no effect on deveIopment of wiId type zebrafish embryos,but after GLP 3 g·L-1 treatment,most of zebrafish embryos dispIayed maIformation and the survivaI rate was onIy 48.6%. GLP 1,2 and 3 g·L-1 had no effect on survivaI and deveIopment of p53-knockout zebrafish embryos. After GLP 2 g·L-1 treatment for 3 d,the SA-β-gaI staining positive rate of wiId type zebrafish embryos was reduced compared with controI group(P﹤0.01),whiIe there was no significant change in p53-knockout zebrafish embryos. The resuIts of RT-PCR showed that GLP 2 g·L-1 treatment depressed p21 and p53 gene expression(P﹤0.05,P﹤0.01),and had no effect on mdm2 and TERTgene expres-sion of wiId type zebrafish embryos. For p53-knockout zebrafish embryos,the TERT,mdm2,p21 and p53 gene expression dispIayed no significant difference after GLP 2 g·L-1 treatment. CONCLUSlON GLP 2 g·L-1 may improve senescence of wiId type zebrafish embryo ceIIs. GLP ≥3 g·L-1 may Iead to death and abnormaI deveIopment of wiId type zebrafish embryos. The improvement of GLP on senescence of wiId type zebrafish embryo ceIIs might be mediated by its down-reguIation of p21 and p53 gene expression.

Objective To evaluate tumor angiogenesis and clinical significance by contrast-enhanced CT in case of non-small cell lung cancer (NSCLC). Methods 30 patients with NSCLC underwent dynamic thoracic CT, and histopathological slides were carefully prepared for VEGF immunohistochemical staining. Maxium attenuations of dynamic CT were compared with VEGF expression levels and lymph-node metastases. Results The mean peak attentation was (36.28?6.41)HU, VEGF positive expressions were in 21 patients, and negative expressions were in 9 patients. VEGF expression levels in patients with NSCLC stage II and III were higher than those in stage I , and in lymph node metastases group, the expression levels of VEGF were also higher than those in non-metastatic nodes. CT enhancement of NSCLC was positively related to VEGF expression,neoplasm stage and lymph-node metastases. Conclusion CT enhancement of NSCLC can reflect tumor angiogenesis and correlate to lymph-node metastases closely, help lung cancer diagnoses,neoplasm stage, and serve as a supplement to the present staging system for lung cancer in biological behavior.
