Objective To investigate the efficacy and safety of using adsorption method combined with warm saline in heparin- free dialysis for patients with high risk bleeding tendency in order to reduce blood ag-glutination in the dialyzer and pipeline. Methods 60 patients with high risk bleeding tendency who were to undergo long- term hemodialysis (HD) were divided into the experimental group and the control group with 30 eases in each group,they both adopted heparin- free dialysis.The control group used saline washing of room temperature, while the experimental group adopted adsorption method combined with warm saline during washing. The completion of dialysis as well as the agglutination in the dialyzer and pipeline were ob-served. Results Number of patients who completed the dialysis were more, the completion rate of dialysis was higher and agglutination of dialyzer and pipeline decreased in the experimental group than those in the control group. Conclusions Agglutination of dialyzer and pipeline can be reduced and the aim of safe and effective heparin- free dialysis can be reached when using adsorption method combined with warm saline.
3.Primary immunodeficiency diseases in children: clinical analysis of 35 cases.
Chinese Journal of Contemporary Pediatrics 2010;12(8):625-629
OBJECTIVETo summarize clinical features of primary immunodeficiency diseases (PID) in children.
METHODSThe clinical data of 35 children with PID from September 2005 to December 2008 were studied retrospectively, including illness history, birth history, family history, clinical manifestations, laboratory findings, diagnosis, treatment and outcome.
RESULTSOf the 35 cases of PID, 6 cases were confirmed with combined T- and B-cell immunodeficiency, 4 cases with X-linked agammaglobulinaemia, 22 cases with selective IgG subclass deficiency, 1 case with common variable immunodeficiency and 2 cases with chronic granulomatous disease. All cases had fever and recurrent infections. Respiratory and digestive tract infections were the most common clinical manifestation. Some of the PID cases lagged behind the normal children of the same age in growth and development. Human gamma-globulin transfusion and anti-infection therapy were administered. Two patients discontinued the therapy, one was transferred to the other hospital and the other 32 patients were discharged following improvement in clinical symptoms.
CONCLUSIONSPID should be considered in children who suffer from recurrent infections and autoimmune diseases or do not respond to long-term use of antibiotics. Immunologic tests should be done as early as possible for the children.

OBJECTIVETo explore a new technique for repair of alveolar cleft by sutural distraction osteogenesis.
METHODSNine 8-weeks mongrel dogs were used in this study, three being in the control group, six in the experimental group. Alveolar cleft model was created surgically in all animals. Two weeks later, a U-shaped distractor made of Ni-Ti memory alloy wire was insterted into the premaxilla to distract the mid-premaxillary suture. When the premaxilla of the cleft side approached the ipsilateral maxilla, periosteoplasty of the alveolar cleft was performed. The distractor was removed at two weeks after periosteoplasty. The results were evaluated clinically, radiographically, morphologically and histologically.
RESULTSThe cleft model in dogs was stable and similar to the human alveolar cleft. In experimental dogs, the premaxilla was moved gradually toward the maxilla so that the cleft was closed. The distracted mid-premaxillary suture showed a gradually widened traingle, with its tip being posterior. The density of the distracted traingle suture was increased gradually. Bony repair was achieved completely at the cleft three months post-periosteoplasy. The morphology of the mid-premaxillary suture was restored.
CONCLUSIONThe alveolar cleft could be repaired by the technique of mid-premaxilla suture distraction.

OBJECTIVETo investigate obesity, overweight and related factors of Kazakh children aged from 6 to 13 years old in Yili, Xinjiang.
METHODSWith stratified cluster sampling method, 2438 Kazakh children aged 6 - 13 from eight elementary schools were recruited from the Yili Kazakh autonomy region from May to June in 2009. Height, weight, blood pressure, waist circumference and hip circumference were measured. Body mass index (BMI) value was used to determine overweight or obesity. The overweight and obesity distribution pattern of gender, age (6 - 7, 8, 9, 10, 11, 12, 13 - 14 years old group) and region (city, county and countryside) was analyzed. Logistic regression analysis was used to analyze the risk factors of overweight or obesity.
RESULTSThe prevalence of obesity and overweight in Yili Kazakh autonomy region was 1.64% (40/2438) (male: 1.62% (20/1232), female 1.66% (20/1206) (χ(2) = 0.69, P = 0.41)), and 5.13% (25/2438) (male: 4.79% (59/1232), female 5.47% (66/1206) (χ(2) = 0.59, P = 0.44)), respectively. The obesity prevalence of 6 - 7 year-old children was 3.72% (8/215), 2.30% (10/435) for 12 year-old group and 2.19% (6/274) for 13 - 14 year-old group. The difference of obesity and overweight prevalence among different age groups was significant (χ(2) = 14.29, P = 0.04). The prevalence of overweight was 8.77% (35/399), 6.92% (74/1069), 1.65% (16/970) (χ(2) = 42.09, P = 0.00) in city, county and countryside. And the prevalence of obesity was 2.75% (11/399), 2.43% (27/1069), 0.30% (3/970) (χ(2) = 18.13, P = 0.00) in city, county and countryside. Logistic regression analysis showed that children with family obesity history (OR = 2.73, 95%CI: 1.42 - 5.22) and culture level of fathers (OR = 1.65, 95%CI: 0.29 - 9.25) were independent risk factors of obesity. There was a correlation between blood pressure and waist-to-hip rate (r = 0.10, P = 0.00). Moreover, the correlation existed between systolic pressure (r = 0.47, P = 0.00), diastolic blood pressure (r = 0.37, P = 0.00) and BMI. Correlation existed between waist circumference (r = 0.81, P = 0.00), hip circumference (r = 0.78, P = 0.00) and BMI.
CONCLUSIONThere is no sex difference of overweight and obesity prevalence in Kazakh children aged from 6 to 13 year-old. Both family history of obesity and culture level of the fathers are factors of obesity and overweight to Kazakh children.

OBJECTIVEIsobaric tags for relative and absolute quantitation (iTRAQ) combined with mass spectrometry were used to screen differentially expressed plasma proteins in cold stress rats.
METHODSThirty health SPF Wistar rats were randomly divided into cold stress group A and control group B, then A and B were randomly divided into 3 groups (n = 5): A1, A2, A3 and B1, B2, B3. The temperature of room raising was (24.0 +/- 0.1) degrees C, and the cold stress temperature was (4.0 +/- 0.1) degrees C. The rats were treated with different temperatures until 12 h. The abdominal aortic blood was collected with heparin anticoagulation suction tube. Then, the plasma was separated for protein extraction, quantitative, enzymolysis, iTHAQ labeling, scx fractionation and mass spectrometry analysis.
RESULTSTotally, 1085 proteins were identified in the test, 39 differentially expressed proteins were screened, including 29 up-regulated proteins and 10 down-regulated proteins. Three important differentially expressed proteins related to cold stress were screened by bioinfonnatics analysis (Minor histocompatihility protein HA-1, Has-related protein Rap-1b, Integrin beta-1).
CONCLUSIONIn the experiment, the differentially expressed plasma proteins were successfully screened in cold stress rats. iTRAQ technology provided a good platform to screen protein diaguostic markers on cold stress rats, and laid a good foundation for further. study on animal cold stress mechanism.

OBJECTIVETo explore the effect of Qiangxin Fumai Granule (QFG, a Chinese herbal preparation for treatment of sick sinus syndrome) contained serum (QFG-S) on sinoatrial node cells during Ca2+ overloading induced by simulated ischemia/reperfusion.
METHODSModel Ca2+ overloading cells were established on sinoatrial node cells from newborn rats, with deprivation of oxygen and glucose to simulate ischemia and with restoration of them to simulate reperfusion. Cells were divided into 5 groups, those in the normal and model control groups were modeled directly and those in the treated groups were pre-cultured with UMEM containing respective medicines in aerobic environment for 30 mm before ischemia/reperfusion simulation. Cell Ca2+ concentration and morphology were observed by invert microscope and fluorescence spectrophotometer.
RESULTSMost cells in the model control group revealed cell edema and deformation, even abscission. By HE staining, many minimal vacuole appeared in cytoplasm, with crumpled nuclear membrane, partially damaged. While cells in the QFG-S treated group, either high-dose or low-dose, were attached grew well, with basically smooth and complete membrane and nuclear membrane, normal in size and shape. The intracellular Ca2+ concentration raised significantly after modeling, but it was much lower in the QFG-S treated group than in the model control group (P < 0.01) and it was not changed obviously in the atropine treated group.
CONCLUSIONQFG-S could diminish the injury of cell induced by simulated ischemia/reperfusion, the acting mechanism for treatment of sick sinus syndrome might be related to its effect in relieving Ca2+ overloading and thus protecting cells from injury.

OBJECTIVETo study the association of fat mass and obesity associated gene rs9930506 polymorphism with overweight and obesity in the Hazakh Children.
METHODSPCR-restriction fragment length polymorphism was used to determine rs9930506 polymorphism in 118 patients with overweight or obesity and 141 controls. Serum lipid level including total cholesterol, triglyceride, high-density and low-density lipoprotein cholesterol, plasma glucose levels, and plasma insulin were monitored by using enzymatic method (Hitachi automatic clinical analyzer) and radioimmunoassay kit respectively.
RESULTSThe genotype distributions of the control group and overweight or obesity group were in the Hardy-Weinberg equilibrium. The frequencies of AA, AG and GG were 0.458, 0.492 and 0.050 in the overweight or obesity group and 0.582, 0.397 and 0.021 in the controls respectively. There was no significant difference in frequencies of AA, AG and GG genotypes between control group and overweight or obesity group (χ(2) = 4.795, P = 0.091), but the frequency of GG + AG genotype in overweight or obesity group (0.542) was higher than that in the controls (0.418) giving significant difference (χ(2) = 3.957, P = 0.047). The frequencies of A allele were 0.703 in the overweight or obesity group and 0.780 in the controls respectively. There was significant difference in frequencies of A allele frequency between controls and overweight or obesity group (χ(2) = 3.986, P = 0.046). In the overweight or obesity group, the plasma glucose levels, BMI and hip circumference were (4.93 ± 0.52) mol/L, (79.70 ± 11.73) and (21.61 ± 2.72) cm in the persons with GG + AG genotype and (4.69 ± 0.56) mol/L, (75.28 ± 11.52) and (19.92 ± 1.98) cm in those of AA genotypes respectively. The plasma glucose levels, BMI and hip circumference of the persons with GG + AG genotype were higher than those of AA genotypes and the statistical significance was also observed (t = 2.430, P = 0.017; t = 2.053, P = 0.042; t = 3.891, P = 0.000).
CONCLUSIONThe present findings suggest that rs9930506 polymorphism on chromosome 16q12.2 may be associated with the development of overweight or obesity in the Hazakh Children, and the polymorphism may have some influence on serum glucose levels, BMI and hip circumference in this population.
