  • Thromboembolic complications (TECs) are clinically important sequelae of nephrotic syndrome (NS). The incidence of TECs in children is approximately 2%-5%. The veins are the most commonly affected sites, particularly the deep veins in the legs, the inferior vena cava, the superior vena cava, and the renal veins. Arterial thrombosis, which is less common, typically occurs in the cerebral, pulmonary, and femoral arteries, and is associated with the use of steroids and diuretics. Popliteal artery thrombosis in children has been described in cases of traumatic dissection, osteochondroma, Mycoplasma pneumoniae infection, and fibromuscular dysplasia. We report of a 33-month-old girl with bilateral iliac and popliteal arterial thrombosis associated with steroid-resistant NS due to focal segmental glomerulosclerosis. Her treatment involved thrombectomy and intravenous heparinization, followed by oral warfarin for 8 months. Herein, we report a rare case of spontaneous iliac and popliteal arterial thrombosis in a young child with NS.

  • The diagnosis of latent Mycobacterium tuberculosis infection (LTBI) is recommended in hematological malignancy patients and before hematopoietic stem cell transplantation (Guidelines for the prevention and management of infectious complications of solid organ transplantation, 2004). Compared to traditional methods such as tuberculin skin test (TST), T-SPOT.TB has been shown to be more specific. In the present study we enrolled 536 patients for whom T-SPOT.TB was performed, among which 295 patients also received the TST test. The agreement (79%) between T-SPOT.TB and TST was poor (x=0.274, P<0.001). The patients with positive T-SPOT.TB results numbered 62 (11.6%), in which only 20 (48.8%) of the 41 receiving the TST test had positive results. A majority of the patients with T-SPOT.TB positive results had some other evidence ofTB, such as TB history, clinical symptoms and an abnormal chest CT scan. Active TB was found in 9 patients, in which 2 had negative TST results. We followed up the patients and no one developed active TB. Our study suggested that the T-SPOT.TB may be more useful for screening LTBI and active TB in hematological malignancy patients and hematopoietic stem cell transplant recipients than the TST test.

  • The Homer protein family, also known as the family of cytoplasmic scaffolding proteins, which include three subtypes (Homer1, Homer2, Homer3). Homer3 can regulate transcription and play a very important role in the differentiation and development for some tissues (e.g. muscle and nervous systems). The current studies showed that Homer3 abnormal expression changes in acute myeloid leukemia (AML). Forced expression of Homer3 in transfected K562 cells inhibited proliferation, influenced the cell cycle profile, affected apoptosis induced by $As_2O_3$ through inhibition of Bcl2 expression, and also promoted cell differentiation induced by 12-O-tetra decanoylphorbol-acetate (TPA). These results showed that Homer3 is a novel gene which plays a certain role in the occurrence and development of AML.

  • Pulmonary arterial thrombosis develops during hypercoagulable states, intra-arterial tumorous conditions, and congenital heart disease accompanied by pulmonary hypertension. Thrombosis in the main pulmonary arterial stump after pneumonectomy can also occur. Herein, we report a very rare case of pulmonary arterial thrombosis in a patient with pulmonary hypertension and a lung destroyed by tuberculosis. He presented with aggravated dyspnea without fever or purulent sputum. His chest computerized tomography scan showed left main pulmonary arterial thrombosis as a convex shape, with the ipsilateral distal arteries and arterioles showing parenchymal destruction. After excluding pulmonary thromboembolism and hypercoagulable disorders, we diagnosed pulmonary arterial thrombosis and treated him with an anticoagulant.

  • Animal models are important tools in thrombosis research and preclinical drug development. In recent studies, ferric chloride ($FeCl_3$) has been widely used to induce arterial thrombosis in a variety of species. The purpose of this study was to find an optimal concentration of $FeCl_3$ and validate this model suited better for thrombosis research. A small piece of filter paper, soaked in $FeCl_3$ solution (10, 20 or 35%, v/v, in distilled water) was topically applied on the carotid artery of SD rats to measure the time to occlusion (TTO) and thrombus weight (TW) to ascertain 35%, as an optimal $FeCl_3$ concentration ($8.63{\pm}0.92min$; p =0.000, $0.79{\pm}0.03mg/mm$; p =0.000, respectively). To validate this experimental model, Ginkgo biloba special extract EGb761 (5, 10 or 30 mg/kg) as a reference agent administered by peritoneal route for 1h prior to the induction of thrombosis, showed significantly delayed TTO in a dose dependent manner ($18.50{\pm}2.17$, $29.17{\pm}1.83$, and $38.00{\pm}1.79min$, respectively) and significantly reduced TW and repaired collagen fibre in the injured vessel compare to vehicle group. Our results provide a simple, reproducible and well controlled in vivo screening system to induce thrombosis in rats by the topical application of 35% $FeCl_3$ to assess the efficacy of the new anti-thrombotic agents.

  • Objectives : The aim of this study was to examine anti-thrombotic effect of traditional herbal extracts in a rat model of ferric chloride ($FeCl_3$)-induced carotid arterial thrombosis. Methods : Thirty minutes prior to a 35% $FeCl_3$ application, Sprague Dawley(SD) rats were injected with the 10 types of traditional herbal extracts (100mg/kg, intraperitoneal injection), respectively. The effect of these herbal extracts was examined for time to occlusion(TTO) using the Laser doppler flow meter and measured for thrombus weight (TW) in $FeCl_3$-induced thrombosis model. Results : In the TTO, Salvia miltiorrhiza (Sm, $2.30{\pm}0.28$ min, p<0.001) and Santalum album (Sa, $2.19{\pm}0.19$ min, p<0.001) showed significantly delayed TTO more than twice compared with Saline-treated group. Cnidium officinale (Co), Psoralea corylifolia (Pc), Scutellatia baicalensis (Sba), Panax notoginseng (Pn), Angelica tenuissima (At), Scrophularia buergeriana (Sbu), Rhus verniciflua (Rv) and Picrasma quassioides (Pq), except for Rhus verniciflua (Rv) also meaningfully impeded TTO more than one fold. In addition, Salvia miltiorrhiza, Santalum album, Cnidium officinale, Psoralea corylifolia and Scutellatia baicalensis significantly reduced TW more than 10% compared with Saline-treated group. Especially, Salvia miltiorrhiza and Santalum album showed the most excellent anti-thrombotic effect among the 10 herbal extracts tested on the restoration of altered TTO and TW. Conclusions : These results suggest that Sm and Sa extracts have outstanding anti-thrombotic effect in $FeCl_3$-induced thrombosis model and is potentially useful as herbal medicines for the treatment and prevention of thrombosis.

  • Cerebral venous sinus thrombosis (CVST) following a closed head injury in pediatric patients is a rare condition, and an early spontaneous recanalization of this condition is extremely rare. A 10-year-old boy was admitted with a mild, intermittent headache and nausea five days after a bicycle accident. The brain computed tomography showed an epidural hematoma at the right occipital area with pneumocephalus due to a fracture of the occipital skull bone. The brain magnetic resonance imaging and the magnetic resonance venography demonstrated a flow signal loss from the right sigmoid sinus to the right jugular vein. The diagnosis was sigmoid sinus thrombosis, so close observations were selected as a treatment for the patient because of his gradually improving symptoms; however, he complained of vomiting 14 days the after conservative treatment. The patient was readmitted for a further examination of his symptoms. The laboratory and the gastroenterological examinations were normal. Due to concern regarding the worsening of the sigmoid sinus thrombosis, the brain magnetic resonance venography was rechecked and it revealed the recanalization of the venous flow in the sigmoid sinus and in the jugular vein.

  • Patients with inflammatory bowel disease are known to have hypercoagulability and an increased risk for venous thromboembolism. The deep veins of the lower extremities and the pulmonary veins are the most common sites of thrombosis in ulcerative colitis. However, hepatic vein thrombosis (Budd-Chiari syndrome) is a very rare extra-intestinal complication of ulcerative colitis in children. We describe a case of hepatic vein thrombosis in a 15-year-old girl with ulcerative colitis who presented with abdominal pain and hematochezia. Doppler ultrasonography and an abdominal CT scan revealed the characteristic filling defects caused by large thrombi in both hepatic veins. These lesions were successfully treated with conventional management for ulcerative colitis and anticoagulation therapy.
