Objective To investigate the clinical features and treatment programs in children with Takayasu arteritis (TA) in order to improve awareness of the disease. Methods A retrospective study of hospi-talized children with TA in our hospital from Jan. 1999 to Dec. 2012 was performed. Results Between the 15 patients with TA, the ratio of male to female was 1∶2. The onset was from 14 months to 15 years old, with average age at (10 ±4) years old. It is according to (the European League against Rheumatism/the Pediatric Rheumatology European Society (EULAR/PRES) criteria for the diagnosis of TA. The most common clinical manifestations are hypertension, which occurred in 13 cases(87%), weak pulse or pulseless in 11 cases (73%), and heart failure in 10 cases (67%). About two-thirds of patients were diagnosed when the onset of heart failure occurred. The most common clinical type was type Ⅱ, which occrred in 9 cases (60%). Antihypertensive drugs, oral steroid and congestive heart failure controlling were the main treatment. Three patients with positive purifiedproteinderivative (PPD) test received anti-TB treatment. Three patients had vascular bypass surgery, one patient had percutaneous transluminal angioplasty. Conclusion TA may be life-threatening and progressive. Many patients are with advanced disease at the time of treatment, so the prognosis is generally poor. Early recognition is necessary to initiate appropriate therapy. The disease should be considered in patients with unexplained arterial hypertension or unexplained inflammatory syndromes without local signs.

Many reasons cause low back pain, such as muscles and ligaments injury, vertebral joints retrogression, spinal canal stenosis, lumbar disc herniation, lumbar spondylolisthesis, spondyloarthritis, infection, tumor and metabolic bone disease. It is in recent years that discogenic low back pain be recognised, especially after the MRI widely applied in clinics. This article makes a summary on discogenic low back pain of recent years from etiology, pathogenesis, diagnosis and therapy.

Objective To study the relationship between the serum level of cholinesterase (CHE) and patient's clinical characteristics and serum levels of lactic dehydrogenate(LDH) and β2-microglobulin (β2-MG) in non-Hodgkin lymphoma(NHL) patients. Methods The levels of CHE, LDH, β2-MG were detected with rate method and immunoassay respectively in 74 patients, and then these patients were divided into low (38 patients) and high level groups (36 patients) according to the serum CHE levels, compared with clinical characteristics and serum levels of LDH and β2-MG between the two groups. Results There were a significant difference in serum levels of CHE, LDH, β2-MG between the low and the high CHE level group [(3714.2 ±1207.1) U/L, (435.7±364.4) U/L, (4.3±2.9) mg/L; (7898.2± 1550.5) U/L, (247.4±134.8) U/L, (2.7±1.2) mg/L, respectively] (t =10.510, P =0.000; t =2.969, P =0.005; t =3.043, P =0.004, respectively). There were no statically significance in age, pathology type, leukocyte and platelet between the low and high serum CHE level groups (t =0.166, P =0.868; x2 =0.751, P=0.386; t =1.626, P=0.111; t =1.987, P=0.056, respectively). Patients with low CHE level group were mostly in Ann Arbor Ⅲ-Ⅳ period (x2 =9.394, P =0.024) and mostly male patients compared with the high CHE level group patients (x2 =5.432, P =0.020). The quantity of hemoglobin in the low CHE level group(97.6±25.8) g/L were lower than that of the high level group (113.4±15.2) g/L (t = 3.230, P =0.002). Conclusion The low CHE level was not correlated with age, pathology type, leukocyte and platelet, but was related with male, Ann Arbor Ⅲ-Ⅳ period, anemia, and higher expression of LDH, β2-MG.
