Aspiration therapy for acute embolic occlusion of the superior mesenteric artery.

Background: Embolic superior mesenteric artery (SMA) occlusion is associated with high mortality rates. Delayed treatment often leads to serious consequences, including intestinal necrosis, resection, and even patient death. Endovascular repair is being introduced, which can improve clinical symptoms and prognosis and decrease the incidence of exploratory laparotomy.

Methods: In this retrospective study, nine patients with SAAs underwent endovascular stent placement in our center between July 2011 and June 2016. Clinical features, imaging findings, treatment outcomes and follow-up results of these SAA patients were retrospectively analyzed.

The fabrication of double layer tubular vascular tissue engineering scaffold via coaxial electrospinning and its 3D cell coculture.

A continuous electrospinning technique was applied to fabricate double layer tubular tissue engineering vascular graft (TEVG) scaffold. The luminal layer was made from poly(ɛ-caprolac-tone)(PCL) ultrafine fibers via common single axial electrospinning followed by the outer layer of core-shell structured nanofibers via coaxial electrospinning. For preparing the outer layernano-fibers, the PCL was electrospun into the shell and both bovine serum albumin (BSA) and tetrapeptide val-gal-pro-gly (VAPG) were encapsulated into the core.

Objective: To evaluate medium-long term patency of below-knee bypass on patients who suffered from diabetic lower limb ischemia.

Methods: Clinical and follow-up data of 51 patients was retrospectively analyzed who underwent 56 below-knee bypass because of diabetes from November 2001 to December 2006. There were 35 male and 16 female with an average age of 68 years.

[Treatment of severe acute deep venous thrombosis in lower extremity].

Objective: To explore the method and effectiveness of treatment for severe acute deep venous thrombosis (DVT) in lower extremity.

Methods: Eighteen patients with severe acute DVT treated in our hospital from January 1, 2002 to December 31, 2008 were retrospectively analysed. All the patients had limb edema and pain, sixteen had limb cyanochroia(one had calf skin ulcer and foot gangrene), two had limb pallor, ten had weakened dorsalis pedis artery pulsation, eight had silent dorsalis pedis artery pulsation.

Objective: To evaluate the effect of surgical bypass and to explore the role of transcranial doppler (TCD) during the bypass operation.

Methods: From March 2003 to February 2008, sixteen patients (4 male and 12 female) with mean age of 32 years old and mean disease course of 7.5 years were treated by surgical procedures.

[Management of difficult, severe and recurrent Budd-Chiari syndrome].

Objective: To investigate the management of complicated, severe or recurrent Budd-Chiari syndrome.

Methods: From February 2004 to August 2007, 28 patients with complicated, severe or recurrent Budd-Chiari syndrome were treated. In this series, 16 patients relapsed after treated with percutaneous transluminal angioplasty or stent deployment, 2 cases relapsed after surgery; and the other 10 were under severe conditions and hard to treat, including malignancy of the inferior vena cava and right atrium.

Transplantation of autologous bone marrow mononuclear cells for patients with lower limb ischemia.

Background: Many treatment options for lower limb ischemia are difficult to apply for the patients with poor arterial outflow or with poor general conditions. The effect of medical treatment alone is far from ideal, especially in patients with diabetic foot. A high level amputation is inevitable in these patients.

[Preliminary in vivo evaluation of tissue engineered venous grafts fabricated based on endothelial progenitor cells].

Objective: To explore the feasibility of the tissue engineered venous grafts (TEVGs) constructed in vitro based on canine autologous bone marrow-derived endothelial progenitor cells (EPCs) and porcine decellularized aortic scaffolds implanted into the canine inferior vena cava.

Methods: To draw out a volume of 8 - 12 ml of bone marrow from the canine (n = 8), to culture and expand EPCs in vitro using conditioned medium. After labeled with a red fluorescent dye PKH26-GL, the cells were seeded onto the luminal surface of decellularized porcine scaffolds with single, rotative method for 4 h.

[Clinical analysis of vascular reconstruction in 56 cases of lower extremity ischemia suffering from infrapopliteal arterial occlusion].

Expansion of canine bone marrow-derived endothelial progenitor cells and dynamic observation.

We cultured bone marrow-derived endothelial progenitor cells by a simple ex vivo expansion method and observed the expansion efficacy. Bone marrow mononuclear cells from five mongrel adult dogs were cultured with EGM-2MV medium in culture flasks coated with fibronectin. Morphology was observed with phase contrast microscopy, and a growth curve was constructed to evaluate the efficacy of expansion.
