Objective To analyse clinical features of dead children in pediatric intensive care unit(PICU) of Children's Hospital of Chongqing Medical University from 2005 to 2014.Methods Clinical data of 917 dead cases in PICU from January 2005 to December 2014 in this hospital were collected,then distribution characteristics of age,length of hospital stay,time of dead and transfer department were analysed.The death cause analysis was conducted as well.Results According to systematic classification of disease,the top 10 leading causes of death for 917 dead cases in PICU from 2005 to 2014 in this hospital were congenital deformity,infectious disease,respiratory disease,injury and poisoning,digestive system disease,tumor,symptoms,signs and abnormal clinical and laboratory findings not elsewhere classified,circulation system disease,nervous system disease,blood system disease.Compared with 2005-2014,the ratio of dead cases due to infectious diseases to the total cases was declined,while that due to non-infectious diseases was increased,there was statistically significant difference (x2 =26.29,P =0.00).Whereas,the ranks of septicopyemia and hand-foot-mouth disease in the rank order of death causes both were increased.Condusion Congenital deformity is the first cause of death in PICU of this hospital.The key to cutting children's mortality is to reduce newborn with congenital deformity.

Chinese cobra (Naja naja atra) cardiotoxins are three-fingered family with 60～62 amino acids bind by four disulfide bonds. CardiotoxinⅢ (CTXⅢ) is one of the major toxic component which can cause hemolysis and cytotoxicity. However, there is no report on the fusion expression of CTXⅢ in soluble form so far. The cloning, expression and purification of recombinant CTX Ⅲ (rCTXⅢ) from Naja naja atra in E. coli and in yeast Pichia pastoris were reported here. CTXⅢ gene, fused with enterokinase in E.coli His-patch Thioredoxin expression system, were expressed in soluble form and released by osmotic-shock treatment. CTX Ⅲ gene was also cloned and expressed in the methylotropic yeast Pichia pastoris pPIC9K expression vector in the first time. The yield of the secretion level was 9.5 mg/L. Using straightforward one-step chromatography procedure, the rCTXⅢ, with three additional amino acids (GYT) at the N-terminal site, was purified to a purity of more than 90% and recovery yield of 65%. The purified rCTX Ⅲ was further characterized by cytotoxic assay with IC50 4.66μg/ml. An effective expression and purification system for recombinant CTXs in P. pastoris was developed, this system will permit us the ready isolation of active cardiotoxins. This protocol can also be easily used for the production of the toxin in a larger scale with low cost.

Objective: To discuss the effect of group counseling on the self-control of male adolescents drug addicts. Methods: 90 male adolescents drug addicts who accepted group counseling were identified as test group, while another 97 male adolescents drug addicts who accepted no intervention as control group. Self Control Scale developed by Grasmick in 1993 was used to assess the outcome. Results: The total scores in the test group decreased from 52.06?6.67 to 47.68? 8.67, and all dimension scores were at significant level (P

Objective:To isolate,identify and purify the Artemisia sieversiana pollen ,the mostly widespread pollen among the Artemisia pollens in China.Methods: Artemisia sieversiana extract was precipitated by saturated ammonium sulfate and then electrophoresed by SDS-PAGE.The molecular mass of each protein band was determined by gel media system.The primary allergen proteins were identified by Western blot.Allergen proteins were purified and identified by DEAE-cellulose DE-52 ion exchange chroma-tography ( IEC) and Western blot.Results: We isolated more than twenty protein bands from Artemisia sieversiana pollen extract , including the most abundant six bands whose Mr were 62 kD,57 kD,38 kD,29 kD,25 kD,14 kD espectively.The protein bands with Mr were 62 kD and 16 kD had the highest binding capacity with the specific IgE from Artemisia pollen allergic patients.The DEAE-cellulose DE-32 IEC was used to purify the primary allergen proteins with Mr 62 kD and 16 kD.Conclusion:The primary allergens of Artemisia sieversiana include the allergen proteins whose Mr are 62 kD,16 kD and the allergen of Mr 62 kD and 16 kD can be purified by chromatography.

Objective To explore the role of transvertebral transposition of the spinal cord in the treatment of the pa?tients suffering from angular kyphoscoliosis with neurologic deficit. Methods Twelve patients with at least 1 year follow?up, in?cluding 5 females and 7 males, suffering from neurologic deficit secondary to angular kyphoscoliosis underwent transvertebral transposition of the spinal cord and posterior correction from January 2005 to June 2013 were retrospectively analyzed. The initial age averaged 21±14 years. The etiologies of deformity were congenital kyphoscoliosis in 9 patients, idiopathic kyphoscoliosis in 3 patients. Preoperative spinal cord function graded by Frankel criteria was 3 cases of grade C and 9 of grade D. The initial major curve was 79.4°±16.2° with a global kyphosis of 68.3°±25.0°. The change of distance between spinal cord and canal on the convex side at the apex was measured on MR images to evaluate the efficacy of transposition;in addition, Cobb angle on coronal and sagit?tal plane was evaluated before surgery, on discharge and at the last follow?up. Results All patients were followed up for 2 years on average (1-5 years). The post operation spinal function evaluated by Frankel criteria were as follow:with grade C of 1 case, grade D of 4 cases and grade E of 7 (7 cases changed one grade, 1 case changed two grades, 4 cases did not change obvious). At the last follow?up, all the cases got obvious recovery of spinal function, with 1 case of grade C and 11 of grade D (10 cases changed one grade, 2 cases changed two grades). The distance between spinal cord and canal on the convex side at the apex changed from 11.9±6.4 mm to 9.8±6.9 mm. After surgery, the major curve improved to 39.3°±15.1° with 50.3%±20.5%correction rate, and the mean loss of correction was 6.1%±7.5%. The mean kyphosis was 41.3°±16.6°, demonstrating a 39.0%±13.0%correction rate im?mediately after operation, and showing 3.1%±4.2%correction loss at the final follow?up. No neurologic complications or no death occurred intra?and post?operatively. No screw or rod fracture, instrumentation loosening and pseudarthrosis were found during fol?low?up. Conclusion Transvertebral transposition of the spinal cord and posterior correction is a useful procedure for the recovery of neurologic deficit secondary to angular kyphoscoliosis, with good results of deformity correction.
