Objective To evaluate the occluder combined with covered stent-graft and coils in treatment of intra-thoracic pseudo-aneurysm at the proximal segment of subclavain artery. Methods The ASD occluder was deployed at the orifice of the subclavain artery via the access of left humeral artery to seal the entrance. The stent-graft was deployed to give additional sealing of the entrance of the left subclavain artery via the access of femoral artery. Finally the coils were deployed at the outlet segment of the pseudo-aneurysm again via the left humorol artery to block the reflux. Results The orifice and the outlet of the left subclavain pseudo-aneurysm were both sealed thoroughly without endoleak,brain accident or arm ischemic symptoms. Conclusions The tri-interventional method utilizing the occluder,covered stent-graft,and the coils in the treatment of the pseudo-aneurysm at the proximal segment of the subclavain artery has the benefits of mini-invasion,thorough sealing,stable frame structure,and assures high security.

Objective To explore the short-and mid-term curative effect and influence factors of hepaticojejunostomy(Kasai operation) for biliary atresia.Methods The clinical data of 66 children with biliary atresia treated with Kasai operation were analyzed retrospectively.The jaundice fading rate,2-year survival rate and influence factors of prognostic were analyzed.Results The jaundice fading rate of 62 cases was 58.1％ after Kasai operatiou.The patients also had a 2-year native liver survival rate of 53.2％.The jaundice fading rate,2-year survival rate of type Ⅰ,Ⅱ and Ⅲ had no significant differences (χ2 =1.91,0.76,all P ＞ 0.05).The 2-year survival rate of children underwent Kasai operation as younger than 60 days was higher rate than that of the children as 61 to 90 days and older than 90 days(χ2 =4.72,P ＜ 0.05).The 2-year survival rate of children with cytoinegalovirus infection and postoperative cholangitis were 43.6％,39.5％,respectively,which were lower than those of children without cytomegalovirus infection and postoperative cholangitis (69.6％.75.0％) (χ2 =3.92,7.46,all P ＜ 0.05).Conclusion Kasai operation is still the preferred method for the treatinent of biliary atresia.Type of the disease was not related with the short-and mid-term effects of Kasai operation.Age at operation was the main factor affecting the prognosis.Therefore,it is very important to make early surgery,enhance the anti-viral treatment and prevent postoperative cholangitis.

OBJECTIVE To investigate the pathogen distribution and antimicrobial resistance in ventilator-associated pneumonia(VAP) in intensive care unit(ICU) of our hospital and provide reference for clinical treatment.METHODS Among 135 patients with VAP in ICU of our hospital,pathogens distribution and resistance rate from sputum culture were analyzed retrospectively.RESULTS Among 188 strains of isolated pathogens in 135 patients,the Gram-negative bacteria accounted for 74.5%,the Gram-positive bacteria 14.4% and the fungi were 11.2%.The predominant pathogens were Pseudomonas aeruginosa(19.7%),Stenotrophomonas maltophilia(18.6%),Klebsiella pneumoniae(16.0%),and Acinetobacter baumannii(14.4%),Staphylococcus aureus(10.6%),Candida albicans(9.6%).The percentage of meticillin-resistant S.aureus(MRSA) was 95.0% and no vancomycin-resistant S.aureus isolate was detected out.Sensitive antibiotics were cefoperazone/sulbactam,imipenem/cilastatin,fluconazole etc.CONCLUSIONS The multi-drug resistant Gram-negative bacilli are the main pathogens in VAP in ICU of our hospital.Cefoperazone/sulbactam and imipenem/cilastatin can be used as first empirical antibiotics for patients with VAP in ICU of our hospital.

Objective To understand the iodine nutritional status of urban and rural pregnant women in Shijiazhuang.Methods Urban pregnant women were selected from 8 neighborhood committees of Chang' an District,Shijiazhuang,while the rural pregnant women were selected from 72 villages of 18 counties in Shijiazhuang.These research subjects were grouped into women with early pregnancy at 1-12 weeks,mid pregnancy at 13-28 weeks and third trimester at 32-40 weeks.Urine samples of the subjects were collected.Arsenic-cerium catalytic spectrophotometry (WS/T 107-2006) was used to determine urinary iodine concentrations (UIC).Results Seven hundred thirty-seven urban pregnant women and 898 cases from the rural areas,totally 1 635 subjects were included into the survey.The median UIC of urban subjects,rural cases,and all pregnant women in Shijiazhuang was 169.0,145.9 and 156.7 μg/L,respectively.The median UIC of the rural pregnant women was significantly lower than that of their urban peers (x2 =54.569,P ＜ 0.05).Urban pregnant women with UIC less than 150 μg/L accounted for 40.30％ (297/737) of the total cases,and rural pregnant women 51.89％ (466/898).The difference was statistically significant between these subjects (x2 =21.864,P ＜ 0.05).The median UIC of pregnant women at third trimester of the urban and the rural areas was 113.5 and 145.6 μg/L,respectively.Though their UICs were not up to the national criteria (150 μg/L),the difference was statistically significant between the urban and the rural subjects (x2 =8.365,P ＜ 0.05).UIC less than 150 μg/L of the urban and the rural pregnant women [60.19％ (65/108) vs 51.96％ (93/179)]at third trimester was not significantly different (x2 =1.844,P ＞ 0.05).Conclusions Iodine deficiency is present in pregnant women in Shijiazhuang City.Iodine deficiency among rural pregnant is more severe than that of peers of urban.The iodine deficiency is more severe in the pregnant population at late pregnancy.Besides iodized salt,food with rich iodine should be supplemented for the pregnant,especially those at the third trimester.It is important to monitor iodine nutritional status dynamically during the pregnancy to keep a proper UIC for the pregnant.

Objective:To study the stress distribution of periodontal supporting tissues of mandibular complete overdenture based on post-core abutment. Methods:3-D finite element method (FEM) was employed to investigate the stress distribution of periodontal supporting tissues of mandibular complete overdenture based on post-core abutment, the stress values of periodontal membrane and lamina dura were calculated and compared with those of natural abutment. Results:The values of stress in distal area of abutment were larger than that in medial area. Post-core reduced periodontal membrane stress value in distal area of abutment cervix dentin, as well as that in apical zone, increased the stress value in distal periodontal membrane of the middle part of root, raised the stress value of distal lamina dura of abutment cervix dentin, while reduced the stress value below the cervix dentin. Conclusion:Abutment tends to incline distally. Post-core can influence stress distribution of periodontal membrane and lamina dura and reduce the stress value on root-end.
