Objective: To analyze relative risk factors of hyperamylasemia after open-heart surgery, and provide basis for clinical prevention and treatment. Methods: A total of 521 adult patients, who received open-heart surgery under general anesthesia and low temperature in our hospital from Jan 1, 2013 to Jun 30, 2013, were selected. The 2ml peripheral venous blood was taken in each patient instant after ICU hospitalization, 24h, 48h and 72h after surgery, then serum was separated and measured for serum amylase level by Somogyi method. According to the measured results of serum amylase level, patients were divided into hyperamylasemia group (serum amylase≥500U/dl, n=76) and non- hyperamylasemia group (serum amylase<500 U/dl, n=445). Single factor and gradual Logistic regression analysis were used to analyze risk factors of hyperamylasemia in patients after open-heart surgery. Results: Gradual Logistic regression analysis indicated that cardiopulmonary bypass (CPB) time and hypotension during operation, renal dysfunction and infection after operation were independent risk factors for postoperative hyperamylasemia (OR=1.02~4.12, P<0.05 or <0.01). Conclusion: During perioperative treatment of open-heart surgery, shortening CPB time, avoiding hypotension during surgery, protecting renal function and preventing infection may reduce morbidity of postoperative hyperamylasemia and improve prognosis of patients.

Objective To study the impact of QseBC on the motility of Salmonella enterica serovar Typhi ( S.Typhi ) . Methods The motility of wild-type ( WT) and null mutants (ΔqseB and ΔqseC) at mid-log phase was investigated by swimming assay.Quantitative RT-PCR was carried out to calculate the transcriptional variation of flhD and qseB among WT,ΔqseB andΔqseC.QseB overexpressing strain was constructed to compare its motility and flhD expression with the wild-type control.Results The result of motility assay showed that the motility of ΔqseB was similar to that of the WT strain , while the motility of ΔqseC was much lower than that of WT .qRT-PCR revealed that compared with WT , the expression of flhD was significantly decreased in ΔqseC while the expression of qseB was increased considerably .The motility of QseB overex-pressing strain was lower .Conclusion The expression of flhD may be regulated by QseBC which has an effect on the motil-ity of S.typhi, and the overexpression of QseB may inhibit the motility .

The angiotensinogen(AGT) expression and angiotensin Ⅱ (AngⅡ ) secretion levels in cultured SD rat mesangial cells were determined. High glucose up-regulated AGT mRNA(0. 29±0.07 vs 0. 20±0. 05,P< 0.05)and protein(0.66±0.23 vs 0.37±0. 15,P<0.05) expression and Ang Ⅱ secretion [(9.85±2.08 vs 7.50± 1. 51) pg/ml,P<0. 05]levels, which were down-regulated by pyrrolidine dithiocarbamate( PDTC) treatment via inhibiting NF-κB activity.

Objective To assess the binding capability of microbubbles targeted to VCAM-1 using the parallel plate flow chamber mimic the pulsatile high-shear flow conditions of artery. Methods Targeted microbubbles were designed by conjugating monoclonal antibodies against mouse VCAM-1 to the lipid shell of the microbubbles via an "avidin-biotin" bridge. The binding and retention of targeted microbubbles to VCAM-1 (MBv) immobilized on a culture dish were assessed in a flow chamber at variable shear stress (0.5～ 16.0 dynes/cm2 ). The pulsatile flow conditions were generated and compared to the continuous flow conditions. The retentive ability of MBv was evaluated by the detachment test. Results The marked binding of MBv were seen in pulsatile and continuous flow conditions at low-shear flow conditions of 0.5 ～ 2dyn/cm2 ,but the binding rate in the pulsatile flow group was higher ( P ＜0. 05) than that in the continuous flow conditions. Furthermore,the marked binding of MBv was still noted at the highest shear rates (4～8dyn/cm2) under pulsatile flow conditions, while it was not observed under continuous flow conditions. The half detachment rate of MBv was high up to (20.7 ± 3. 1)dyn/cm2. Conclusions The targeted microbubbles binding to VCAM-1 specific and effective at high-shear stress under pulsatile flow conditions. The molecular ultrasound imaging can be potentially used in the high-shear conditions artery system.

Purpose The diagnosis, treatment and prognosis of benign and malignant biliary stricture are significantly different. This study aims to evaluate the quantitative analysis of biliary structures using magnetic resonance cholangiopancreatography (MRCP) combined with dynamic contrast enhanced CT (DCE-CT).Materials and Methods The quantitative parameters of MRCP and DCE-CT imaging data from 27 patients with benign biliary stricture (benign group) and 30 patients with malignant biliary stricture (malignant group) were retrospectively analyzed. The wall thickness, stricture length and diameter, proximal ductal dilatation and degree of enhancement in two groups were compared, and its correlation was analyzed to evaluate the accuracy of MRCP and DCE-CT.Results There were significant differences in wall thickness [(3.2±2.0) mmvs (2.1±0.6) mm], stricture length [(15.8±8.1) mmvs (9.5±6.5) mm] and diameter [0 mmvs (2.0±0.9) mm], proximal ductal dilatation and the degree of enhancement [(12.7±3.6) mmvs (9.3±2.7) mm] between the two groups (t=2.825, 3.270, 4.025,P<0.001;Z=-3.909,P<0.001). Multivariable stepwise regression analysis showed that the wall thickness and diameter, and the CT HU in portal venous and equilibrium phases combined with CT plain scanning were significant predictors of malignant biliary strictures (t=-6.424-2.309,P<0.05). The sensitivity, specificity, inter-modality agreement and Youden index of MRCP and DCE-CT in diagnosing 57 patients with biliary stricture were 96.67%, 100.00%, 98.25% and 0.97, respectively; with statistical significance in predicting benign and malignant biliary stricture (AUC=0.994,P<0.001).Conclusion Using MRCP and DCE-CT, the wall thickness and diameter of the stricture, and the difference in CT HU in portal venous and equilibrium phases combined with CT plain scanning are valuable in differential diagnosis of benign and malignant biliary stricture.

Objective To investigate the relationship between the level of serum uric acid(SUA) and carotid atherosclerosis in male patients with type 2 diabetes mellitus(T2DM). Methods A collection of 579 male T2DM patients with or without carotid atherosclerosis were grouped based on quartiles of SUA. Age, SUA, smokers, duration, body mass index(BMI), blood pressure, total cholesterol(TC), triglyceride(TG), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), blood urea nitrogen(BUN), creatinine(Cr), and HbA1C were determined in all subjects. The plaques in carotid arteries and intima-media thickness(IMT) were measured with high-resolution ultrasound. Results BMI, systolic and diastolic blood pressures, TG, and Cr showed a gradual increase, while HDL-C and HbA1C showed a gradual decrease according to the higher SUA quartiles in male T2DM(P＜0.05). Nevertheless, the detectable rates of smokers, duration, age, TC, LDL-C, and BUN had no relationships with the SUA quartiles(P＞0.05). The detectable rate of carotid atherosclerosis and the thickness of carotid plaque were positively associated with the levels of SUA in male patients with T2DM(P＜0.05). However, intima-media thickness of carotid arteries did not illustrate the correlation with the levels of SUA in male T2DM patients(P＞0.05). Age, HbA1C, and SUA were independent factors of carotid atherosclerosis in these patients by logistic regression(P＜0.05). Conclusion The levels of SUA seems to be associated with the occurrence and development of carotid atherosclerosis in male patients with T2DM.

BACKGROUND:In view of the unavoidable problems of autogenous and al ogenous bone grafts, it is an urgent need to develop biodegradable bone substitute materials, among which is calcium phosphate material that has become a hot spot in the domestic and foreign research. OBJECTIVE:To develop a biodegradable calcium phosphate material for bone repair based on tetracalcium phosphate (TTCP). METHODS:The biodegradable calcium phosphate cement made from TTCP, dicalcium phosphate anhydrous and different constituents of curing liquids was prepared under room temperature (about 25 ℃). The effects of solid components, liquid components as well as calcinations and drying temperature on the physical and biological performances were detected through X-ray diffraction test, hardness test, decay in a simulated body fluid, hemolysis and cytotoxicity tests, respectively, to select the bone repair material with excel ent performances. RESULTS AND CONCLUSION:When the calcination temperature was lower than 1300 ℃, TTCP was rarely available;only close to 1400 ℃, the relatively pure TTCP was gained. A large number of pure TTCP were gained by rapid cooling because of avoidance of the moisture impact, but slow cooling made the main products to be hydroxyapatite, suggesting that rapid cooling is essential to obtain pure TTCP. With the increase of the proportion of citric acid solution in the liquid phase, the pH values and the hemolysis rate in the bone cement soak solution were increased gradually, illustrating that citric acid solution is easy to induce hemolysis. In vitro cel experiments showed that the hemolysis rate of bone cement with a solution of 2:1 NH4/Na ratio was the lowest, and the biocompatibility was the best, which was the most favorable to cel growth. Cements was made of calcined powders sieved at 1400 ℃ and showed the shortest initial setting time, least effect on pH values, lowest disintegration rate and hemolysis rate, and slightest inhibition effect on the cel proliferation, indicating that the bone cements made of sieved powder after 1400 ℃ calcination is more suitable for clinical application.

OBJECTIVEThere are many factors affecting the sensory integration training (SIT) effects in children with autism. This study explored the influential factors for SIT effects in the aspect of the model of sensory processing.

METHODSNinety-three autistic children aged 1.8-8.3 years were evaluated by the autism behavior checklist (ABC) and the Dunn's model of sensory processing. The SIT effects were evaluated by the sensory integrative schedule. The effects of sex, age, ABC scores and the Dunn's model of sensory processing were investigated by logistic regression analysis.

RESULTSLogistic regression analysis showed that ABC scores (Wald=6.768, <0.01) and the Dunn's model of sensory processing (Wald=13.549, <0.01) were influential factors for the SIT effects. The Dunn's model of sensory processing was shown as a more important influential factor. Sex (Wald=1.549, >0.05) and age (Wald=0.010, >0.05) were not related to the STT effects.

CONCLUSIONSThe Dunn's model of sensory processing is a major influential factor for the SIT effects in children with autism.
