X-linked agammaglobulinemia (XLA) is a primary immunodeficiency disorder caused by germline mutations of B-cell tyrosine kinase (BTK) gene. It is characterized by decreased serum immunoglobulins levels and circulating mature B cells. This defect in humoral immunity leads to increased susceptibility to infection. Pyoderma gangrenosum (PG) is an uncommon, ulcerating, neutrophilic dermatosis. Here we report PG in an 8-year-old patient with XLA. The patient received intravenous immunoglobulin treatment in conjunction with prednisone and topical application of 0.03% tacrolimus ointment and the ulcer was almost completely healed in the 2 weeks of follow-up. The coexistence has been rarely reported. XLA may be a possible cofactor in the pathogenesis of PG.

OBJECTIVETo investigate the methods and effects of secondary intervention for mid-long term complications of endovascular repair (EVR) in aortic diseases.

METHODSFrom May 1999 to Jun 2007, 21 patients with mid-long term complications after EVR were treated in our center. Of these cases, 15 cases received first EVR for abdominal aortic aneurysm (AAA), 3 cases for thoracic aortic aneurysm (TAA) and 3 cases for aortic dissection (TAD). The mid-long term complications included 11 cases of type I endoleak, 4 cases of type II endoleak, 2 cases of type III endoleak and 4 cases of migration of stent grafts. Proximal or distal extensions were used for type I and III endoleak in 9 cases. Fenestrated, scallop and bifurcated stent grafts were used to reconstruct the aortic arch in 3 cases. Emboli technique was used in treating type II endoleak. Thrombectomy and bypass technique were used in 4 cases with stent graft limb occlusion. One ruptured AAA accepted open surgery.

RESULTSSecondary endovascular technique were undergone in 20 (95.2%) cases. One case died in 30 days after the secondary intervention and endoleak remained after the secondary operation in 5 cases. Three cases died of the secondary intervention.

CONCLUSIONSEndoleak and limb occlusion were the chief mid-long complications after EVR. Secondary endovascular technique can be used in most cases and carries great challenges in aortic arch lesions.

OBJECTIVETo evaluate the effect of the compound of Dan-shen root and azone for scar treatment.

METHODSThe rat skin in vitro and the human skin in vitro and vivo were separately examined their permeability of the mixture of the Dan-shen root and azone. The 301 patients with hypertrophic scar were randomly divided into two groups: one treated with elastic cloth paste (including silicone) contained in Dan-shen root with azone, and the another treated with only elastic cloth paste (including silicone).

RESULTSThe permeability of Dan-shen root with azone, passing through the rat skin in vitro and the human skin in vitro and vivo was significantly higher than both the distilled water and the normal saline (P < 0.05). In the clinical study for treatment of the hypertrophic scars, the efficient rate of the group with the Dan-shen root with azone was significantly higher than the control (91.4% vs. 71.3%) (P < 0.01).

CONCLUSIONThe Dan-shen root with azone could be easier to permeate the skin and more effective to treat the hypertrophic scar.

OBJECTIVETo prevent and manage frequent complications after endovascular repair of infrarenal abdominal aortic aneurysm (AAA).

METHODSThe data of 71 cases of infrarenal abdominal aortic aneurysm (AAA) treated by endovascular repair were analysed retrospectively. The reasons, managements, results and prognosis of frequent complications were investigated.

RESULTSSeventy-one cases of infrarenal AAA were treated by endovascular repair with 100% success rate. There was no surgical conversion to open aneurysm repair. There were 8 cases of primary endoleak, 1 case of nervous complication and acute thrombosis. An average follow-up period was 26 +/- 5 months. Three persistent endoleaks and 4 secondary endoleaks were found during the follow-up period. The endoleak rate was 9.8% (7/71) within 1 month postoperatively and mortality rate was 1.3% (1/71). Total mortality rate was 4.2% (3/71). Two patients died from acute myocardial infarction and one from acute heart failure.

CONCLUSIONSEndovascular treatment of abdominal aortic aneurysm is technically feasible and can effectively exclude aortic aneurysms from the circulation. Endoleak is a chief complication after endovascular repair of infrarenal AAA.Additional procedures and follow up are very important. Endoleak with enlarged aneurysm should be treated actively.

The aneurysms at the initial segment of splenic artery are rare. This paper aimed to investigate the methods to treat the true aneurysm at the initial segment of splenic artery by aneurysmectomy plus vascular reconstruction. Retrospectively reviewed were 11 cases of true aneurysm at the initial segment of splenic artery who were treated in our hospital from January 2000 to June 2013. All cases were diagnosed by color ultrasonography, computer tomography (CT) and angiography. Upon resection of the aneurysm, the auto-vein transplantation was performed in situ between the hepatic artery and the distal part of the splenic artery in 1 case; the artificial vessel bypass was done between the infra-renal aorta and distal portion of the splenic artery in 7 cases; the splenectomy was done in 2 cases; the splenectomy in combination with ligation of multiple small aneurysms were performed in 1 case. All cases were cured and discharged from the hospital 10-14 days after operation. A 1-14 year follow-up showed that 9 cases survived, and 2 cases died, including 1 case who died of acute myocardial infarction 2 years after aorta-splenic artery bypass operation and 1 case who died of acute cerebral hemorrhage 5 years after aneurysm resection and the splenectomy. Among 6 cases receiving aorta-splenic artery bypass, 1 gradually developed stenosis at anatomosed site, which eventually progressed to complete occlusion 2 years to 6 years after operation, without suffering from splenic infarction because the spleen was supplied by the short gastric vessel and its collaterals. The other 5 cases receiving aorta-splenic artery bypass and 1 case undergoing autologous vascular transplantation did not develop stricture or pseudoaneurysm at the stoma. Our study showed that the aneurysmectomy plus vascular reconstruction is a better treatment for aneurysm at the initial segment of splenic artery.

OBJECTIVETo discuss the change of blood supply pattern in visceral arteries of Stanford B dissection. The visceral arteries include celiac trunk (CA), superior mesenteric artery (SMA) and renal artery (RA).

METHODSBy retrospectively analysing the clinical data of 52 cases with Stanford B dissection, the blood supply pattern of visceral arteries was confirmed by aortography and the changes before and after endovascular repair were compared.

RESULTSAfter repair: the stenosis lesions disappeared in 7 cases supported by true channel completely but one. Twenty-two visceral arteries supported by true and false channel simultaneously recovered true channel chiefly but one. One recovered true channel chiefly and one had no change in 2 visceral arteries supported by false channel completely. Four recovered true channel chiefly and one had no change in 5 visceral arteries without blood support. 88.9% blood support got better and 11.1% blood support had no change in 36 damaged visceral arteries after endovascular repair.

CONCLUSIONBlood support from true and false channel simultaneously is the chief pattern in the injured visceral arteries before repair; Endovascular repair technique is benefit to recovering the blood support of true channel.

OBJECTIVETo study the current situation and factors influencing the behavior of fruit and vegetable intake in adolescents, and to discuss health education strategy related to the behavior.

METHODS1677 students were selected from primary school and middle school in urban area of Hangzhou by a multistage sampling method. The behavior of fruit and vegetable intake was surveyed by questionnaires of the patient-centered assessment and counseling for exercise plus nutrition project (PACE+) for adolescent-scale of fruit and vegetable consumption, and analyzed by Transtheoretical Model on the servings of intake, the stage of change, process of change, decisional balance and the current status of self-efficacy.

RESULTSThe average intake of fruit and vegetable in adolescents was (3.21 +/- 1.50) servings per day ("one serving" means 100 g cooked vegetable or 100 g fruit). The behavior of consuming fruit and vegetable in most of the adolescents was in the contemplation stage, accounting for 36.91% (619/1677). The process of behavior change, decisional balance (Pros) and self-efficacy existed a positive correlation with the process of stage (r(process) = 0.38, r(decisional balance (Pros)) = 0.26, r(self-efficacy) = 0.33, t values were 16.78, 11.02 and 14.31, P < 0.05). The servings of fruit and vegetable intake existed a positive correlation with stage transition and self-efficacy (beta(stage transition) = 0.665, t = 35.07, P < 0.05; beta(self-efficacy) = 0.050, t = 2.63, P < 0.05), and existed a negative correlation with decisional balance (Cons) (beta(decisional balance (Cons)) = -0.051, t = -2.84, P < 0.05).

CONCLUSIONFruit and vegetable intake of these adolescents are under the recommended dietary intake. Along with behavior stage development and self-efficacy improvement, the intake of fruit and vegetable also increased correspondingly. Intervention strategies should aim at improving the awareness of adolescents on the health benefits of fruit and vegetable intake and promoting their confidence to reach the recommended servings.

OBJECTIVETo investigate the treatments of left subclavian artery (LSA) in endovascular repair (EVR) of thoracic aortic aneurysm (TAA) and thoracic aortic dissection (TAD).

METHODSIn 54 TAD or TAA cases, all of the proximal landing zone (PLZ) were less than 15 mm and only the LSA was needed to be treated in EVR, the following methods and techniques were used in the treatments of LSA: complete cover, partial cover, endovascular reconstruction following complete cover, surgical reconstruction before complete cover.

RESULTSDSA was used to evaluate the condition of cerebral circulation in all cases. Forty left subclavian arteries were covered completely. Ten were covered completely after right subclavian artery (RSA)-LSA or left common carotid artery (LCCA)-LSA bypass. PTA and stent in LSA was done in 3 cases. In 1 case, LSA was covered completely first, and then the graft was punctured and bare stent was fixed after inflation by cutting balloon. All of the ancillary techniques were enforced successfully. No severe complications were found in brain and upper extremity. The proximal endoleak rate was 17% (9/54). In the 40 cases whose LSA were not reconstructed, the primary left subclavian steal syndrome (LSSS) happened in 8 cases (20%) and the primary average systolic pressure of left brachial artery was 63 +/- 24 mm Hg.

CONCLUSIONSEVR can be enforced safely and efficiently in TAA and TAD with short PLZ by some ancillary endovascular or surgical techniques. The methods to treat the LSA depend on the condition of the cerebral circulation.

OBJECTIVETo design and manufacture a modular branched stent-graft system of endovascular reconstruction of the aortic arch in canine, and to investigate the feasibility of endovascular repair.

METHODSAfter the length and the diameter of ascending aorta, aortic arch and super-arch branched vessel measurement, a modular branched stent-graft system, including two pieces bifurcated stent-graft and one piece straight stent-graft, was designed and manufactured. Under X-ray fluorescope, these three modulars were accessed from right subclavian, left subclavian and femoral artery respectively and connected one by one to reconstruct the aortic arch. The shape and structure of stent-grafts, haemodynamics in aortic arch and endoleak were observed.

RESULTSEight of ten operations were completed successfully. Two dogs died of obstruction of coronary artery and artery rupture of left subclavian respectively during operation. In the eight successful cases, two proximal type I endoleaks were observed, and no other type endoleak occurred. The shape and the localization of stent-grafts were fine, and the coronary artery and carotid artery were unobstructed.

CONCLUSIONIt is feasible to reconstruct aortic arch of canine by modular branched stent-graft, and it is significant to direct the research of reconstruction of human aortic arch.

BACKGROUNDAs an alternative to open aneurysm repair, endovascular aortic repair (EVAR) has been applied to ruptured abdominal aortic aneurysm (rAAA). The aim of this study was to evaluate the immediate and long-term outcomes of EVAR for rAAA.

METHODSFrom July 1997 to September 2007, 20 men and six women with rAAA (median age, 68 years) were treated with EVAR. Most patients with suspected rAAA underwent emergency computed tomographic angiography (CTA). The procedure was performed under general or local anesthesia. Endovascular clamping was attempted in hemodynamically unstable patients. Bifurcated endografts and aorto-uni-iliac (AUI) endografts with crossover bypass were used. Patients had CT scan prior to discharge, 3, 6, 12 months after discharge, and annually thereafter.

RESULTSTime between diagnosis and EVAR ranged from 1 hour to 5 days. EVAR was performed under general anesthesia in 21 patients, and under local anesthesia in five patients. Endovascular aortic clamping was performed in four patients. There was no conversion to open surgery during EVAR. Stent-graft insertion was successful in all patients. One patient died during EVAR from acute myocardial infarction. Ten patients had systolic blood pressure < 80 mm Hg. Eleven patients received a blood transfusion. Mean aneurysm size was (47 +/- 12) mm. Mean ICU stay was (8 +/- 3) days, mean hospital stay (18+/- 6) days, and mean procedure time (120 +/- 32) minutes. The 30-day mortality was 23% (6/26 patients), and major morbidity 35% (9/26 patients). Early endoleak occurred in 8/26 patients (31%). The mean follow-up was (18 +/- 7) months. No patient demonstrated migration of the stent-graft.

CONCLUSIONSEVAR is a safe and effective option for treatment of acute rAAA, independent of the patient's general condition. Immediate and mid-term outcomes are favorable, but long-term outcome is unknown. Multi-center studies are necessary to establish the role of EVAR for rAAA.
