Objective To explore the application of self-expanding stent and seperable detachable coil for interventional therapy in patients with wide-necked intracranial aneurysm.Methods 32 patients with wide-necked intracranial aneurysm received the interventional therapy by self-expanding stent and seperable detachable coil.After operation,the situation of the aneurysm occluded were observed by DSA immediately and followed up.Results The stents were successfully deployed in the 32 patients.The seperable detachable coils were occluded in the aneurysms in 29 cases.After operation immediately,the DSA showed that the aneurysms in 18 cases were completely occluded by seperable detachable coils,7 cases were 95% occluded,4 cases were 90% occluded.In the other 3 cases,the aneurysms were too small to be filled by seperable detachable coil,the stents were used only.All the parent arteries were no stenosis.18 h after operation,1 case died from multiple hemorrhage caused by thrombasthenia.Follow-up from 3 months to 1 year,DSA re-examination in 21 cases.Compared with the image immediately after operation,the imagings of DSA were no change in 12 cases,residual necks were disappeared in 5 cases and increased in 1 case.In the 3 cases which stents used only,the aneurysms were no development completely in the 2 cases and decreased in 1 case.6～18 months followed up in 26 cases,the rebleeding and cerebral infarction were no occurred.Conclusions The self-expanding stent is very flexible,secure,and effective.It can good support for the wide-necked aneurysms to be occluded by seperable detachable coils and effective promoting the small aneurysms healing.

Objective To establish a TaqMan-MGB fluorescent probe characterized real-time polymerase chain reaction ( qPCR) method for detecting retinoic acid induced genes G ( RIG-G) in human acute promyelocytic leukemia ( M3 ) .Analyze RIG-G expression levels in peripheral blood of both normal persons and M3 patients and explore its diagnosis value for M 3.Methods Methodology establishment study.A detection method and standard curve of TaqMan-MGB real-time PCR were established after designing specific primers and TaqMan-MGB fluorescence probe of human RIG-G gene and using reverse transcription complementary DNA ( cDNA) as a template.The performance of this method was evaluated in specificity, accuracy, precision, analytical sensitivity and interference substances . Twenty clinical specimens with M3 were quantified RIG-G expression so as to evaluate the correlation between peripheral blood and bone marrow samples .Meanwhile , the results of RIG-G expression in peripheral blood of 40 normal specimens and 20 patients with M3 were analyzed by t-test.And receiver-operating characteristic curve ( ROC ) was used to analyze the detection efficiency of M 3.Results There was a good linear relationship between log value of RIG-G standard substance and threshold cycle number ( Ct ) ( standard curve equation:Y=-3.539X+42.952,R2 =0.999).New method was used to detect standard substance . The deviation between observed and expected values was <5% (r=0.999).Three concentration samples (107 ,104 ,101 copies/μl) were selected for precision test.Intra-assay coefficients of variation were 1.38%, 2.31% and 1.38%, respectively , and intre-assay coefficients of variation were 0.71%, 1.17% and 5.07%, separately.All were less than 10%.The sensitivity of this method was 101 copies/μl.There was a good correlation of RIG-G results between peripheral blood and bone marrow in M 3 patients(r=0.996, b=0.973).But there was no significant difference between this two group results (t=0.099, P>0.05). However , there was obvious difference of RIG-G value in peripheral blood between control group and M 3 patient group (U=18,P<0.001), 3.62 ×104(1.61 ×104 -4.90 ×104)copies/μl for controls and 7.10 ×102 (5.43 ×102 -2.21 ×103 ) copies/μl for M3 patients, respectively.Conclusions Successfully establishe a TaqMan-MGB real-time PCR method for detecting RIG-G gene in peripheral blood.The accuracy, precision, sensitivity and specificity are good .It could provide necessary help in early diagnosis and monitor treatment of clinical M3 patients.
