Objective To evaluate the effect of percutaneous device closure guided by transesophageal echo-cardiography (TEE)on atrial septal defect(ASD)via right internal jugular vein(RIJV)in children.Methods A total of 8 cases with secundum ASD were recruited as candidates to receive percutaneous device closure via RIJV between July 22 and November 5,201 5 in Heart Center,Dalian Children′s Hospital.In this group,5 boys and 3 girls who were 5 months to 1 0 years old were included.The youngest patient was a 30 weeks premature infant of 5 months old,with 3 -month correction gestational age.All patients were clearly diagnosed as ASD by transthoracic echocardiography(TTE) before operation.Five patients had single central type ASD which were 5 -8 mm in diameter,and 3 patients had multi-ple(1 biforate and 2 cribriform)ASD which were 1 0 -1 2 mm in shunt range.New type Fustar curve adjustable sheath was delivered after RIJV accessed.By passing through the ASD by adjusting the depth and bending of the tips of sheath,then the device was delivered and released to close the ASD.The procedures were always guided and monitored by TEE.After the devices were released,the position of device,residual shunt,and the effect of valves were assessed by TEE or TTE.Results All patients were tested with TEE and TTE after procedure,devices were stable and well shaped,and the defects were closured well without any residual shunt.All the patients were followed up more than 6 months.No hydropericardium,thrombogenesis,tachyarrhythmia,complete atrioventricular block or other complications were found.Conclusions To close ASD with new type curve adjustable sheaths via RIJV may have wide indications, short operation path,well curative effect,minimal invasion and fast recovery in pediatrics,especially fit for the small age children with a big ASD who are difficult to treat via femoral vein.

Objective To investigate the correlation between red blood cell distribution width (RDW) and urinary protein /cre-atinine ratio(TPCR) in elderly patients with essential hypertension .Methods TPCR ,Cr ,CysC ,eGFR ,TG ,TC ,LDL-C ,ApoA1 , ApoB and blood routine were detected in 801 elderly patients with essential hypertension and 98 healthy people .The differences of these indexes were compared between the two groups and the difference of RDW was compared among different grades of hyperten-sion .The hypertension patients were divided into two groups by TPCR<200 mg/g Cr or ≥200 mg/gCr ,the levels of RDW were compared between the two groups and the correlation between TPCR with RDW was analyzed .Results The age ,gender ,Cr and HB had no statistical differences between the hypertension group and control group (P>0 .05);TPCR ,TG ,TC ,LDL-C ,ApoB and RDW levels in the hypertension group were increased ,the ApoA1 ,CysC and eGFR levels were decreased ,the differences were sta-tistically significant (P<0 .05);the RDW level in the hypertension group was significantly higher than that in the control group ,the difference was statistically significant(P<0 .05);the RDW level was increased with the increase of blood pressure level ,the differ-ence was statistically significant(P<0 .05);the Pearson correlation analysis showed that RDW was positively correlated with TPCR (P<0 .05) .Conclusion The RDW level is elevated in the essential hypertension group ,and correlated with the level of TPCR .

The actual incidence of gastrointestinal stromal tumor (GIST) is underestimated.With the progression of awareness and development of examination methods,the detection rate of small GIST (diameter ＜ 5 cm) is increasing year by year.These patients always had no obvious clinical symptoms,and were often detected with small GIST in physical examination unexpectedly.Combination of endoscopic ultrasound and radiographic examination is helpful in detecting small GIST.Aggressive surgical complete resection should be considered in case of a definitive diagnosis.Laparoscopic resection is becoming the standard surgical treatment currently.For micro GIST (diameter ＜2 cm),especially micro gastric stromal tumor,current guidelines recommend close observation.Some scholars advocate that endoscopic resection is feasible for the treatment of micro GIST,while we think that the efficacy of individualized treatment is better after identifying the potential malignancy of micro GIST.
