Objective To investigate the change of serum prealbumin (PA) and C-reactive protein (CRP) in burn patients and its clinical significance.Methods Sixty eight cases of burn patients were divided into two groups,group Ⅰ [n=38,with total burn surface area less than 15% of total body surface area (TBSA)] and groupⅡ(n=30,with total burn surface area more than 50% of TBSA). Thirty healthy people were set as healthy control group. Particle enhanced immunoturbidimetic assay was applied to detecting the serum levels of PA and CRP for all subjects on the day 1 after burns.Results The CRP level was much higher and serum level of PA was much lower in group Ⅱ than that of group Ⅰ,respectively. There existed significant negative correlation between PA and CRP level.Conclusion The level of serum PA decreases significantly along with total burn surface area expansion. PA can be used as a sensitive marker for estimation of inflammation degree after burns.

Objective To discuss the comparability of ALT, AST, CK and LDH results by ap- plying three different vacuum tubes (no additive tubes, separation gel coagulation promoting tubes and other coagulation promoting tubes) for venous blood samples, and to provide evidence for clinical tests. Methods Fast venous blood from 26 healthy blood donors were collected in test tubes without additives, separation gel coagulation promoting tubes and other coagulation promoting tubes. Olympus AU5400 Biochemical Analyzer was applied to examining serum ALT, AST, CK and LDH for all pre- pared serum samples. Results There was no statistical difference of serum ALT, AST, CK and LDH level collected in test tubes without additives, separation gel coagulation promoting tubes and other co- agulation promoting tubes. With the no additive tubes as the standard tubes, the above result bias be- tween separation gel coagulation promoting tubes and other coagulation promoting tubes were clinically acceptable. Conclusion There is credible comparability of serum ALT, AST, CK and LDH level a- mong different kinds of venous blood samples collected in test tubes without additives, separation gel coagulation promoting tubes and other coagulation promoting tubes. The separation gel coagulation promoting tubes and other coagulation promoting tubes can substitute test tubes without additives for ALT, AsT, CK and LDH determination.

Objective:To observe the effect of calcitonin gene-related peptide (CGRP) on the expression of osteoprotegerin (OPG) and receptor activator of nuclear factor-kappaB ligand (RANKL) in osteoblast cells through an in vitro breast cancer cell and osteoblast cell co-culture system. Methods:The metastatic breast cancer MDA-MB-231 or MDA-MB-435 cells were co-cultured with osteoblast MG63 cells to establish an in vitro microenvironment of bone metastasis of breast cancer. After treated with CGRP(1?108 mol/L),OPG and RANKL mRNA and protein expressions in osteoblast MG63 cells were examined by RT-PCR and Western blotting. Results:Expression of RANKL in osteoblast MG63 cells was up-regulated at both mRNA and protein levels when osteoblast MG63 cells were co-cultured with breast cancer MDA-MB-231 or MDA-MB-435 cells,while those of OPG in osteoblast MG63 cells were both down-regulated (P

Objective:Atrioventricular nodal reentrant tachycardia(AVNRT) is a common type of arrhythmia,for which radiofrequency ablation(RFCA) is the first therapeutic option.This study is to investigate the causes of 16 cases of temporary atrioventricular block(AVB) during RFCA and 2 cases of permanent AVB after RFCA in common and refractory AVNRT.Methods: We performed RFCA for 77 AVNRT patients by gradually increasing the ablation time,energy and frequency.Generally we chose the lower zone as the first position of ablation and,if invalid,moved the catheter gradually up to the middle or upper zone.Then we analyzed the correlation of AVB with A/V and H-wave in different positions.Results: The AVB risk was increased with the upward movement of the ablation zone and increase of A/V or H-wave(P 0.05). Conclusion: The method of gradually increasing the ablation time,energy and frequency can prevent temporary from permanent AVB.In the common AVNRT group,the middle and lower zone ablation,the multiple-peak A wave,small A wave and big V wave(A/V ≤ 0.45?0.37) with no H wave or H≤0.003?0.01 mV could significantly decrease the risk of RFCA related AVB,but the risk of AVB remains among the refractory AVNRT patients with CSO abnormality or expansion,even if with ablation in the lower zone.

Objective:To analyze the correlation between the glycosylated hemoglobin and immunologic function in patients with type 2 diabetes.Methods:Clinical data of patients with type 2 diabetes received treatment at our hospital from 2011 to 2014 was analyzed (Group A) and also included the healthy control as Group B.Results:A total of 75 patients were analyzed,Group A 45 cases and Group B 30 cases.Group A had a higher level of glycosylated hemoglobin than that of Group B , the difference was statistically significant(8.12±3.45 vs 4.87±1.65;t=4.472,P<0.001).Group A patients had lower levels of IgA,IgM and CD4/CD8 when compared with Group B ,the difference was statistically significant ( P<0.05 ).Correlation analysis shown the glycosylated hemoglobin had significantly negative correlation with IgA ,IgM and CD4/CD8 ( P<0.05 ).Conclusion: Patients with type 2 diabetes have a low immune function which are related to high level of Glycosylated hemoglobin.

A strain of Cellulosimicrobium cellulans Ha8 was studied on its morphological, biological characteristics and its utilization of several kinds of benzoic compounds, the results showed this strain was Gram-positive, the long rod-shaped cells were changed into short rod-shape gradually. pH value from pH 6.0 to pH 9.0 and the temperature from 20 ℃ to 40 ℃ were good for its growth. It could not only hydrolyze protein and starch, use cellulose and pectin, decomposite chitin, liquify gelatin and fix nitrogen, but also use phenol, xylene, benzoic, cinnamic acids and diphenlamine as the sole carbon resource for its growth. It could tolerate 0 mmol/L~30 mmol/L, 0 mmol/L~8 mmol/L, 0 mmol/L~30 mmol/L, 0 mmol/L~15 mmol/L and 0 mmol/L ~ 40 mmol/L of benzoic acids, phenol, xylene, cinnamic acids and diphenlamine seperately, but could not use 2,4-dinitrophenol, o-Nitrophenol, 2-Methoxyphenol, aminobenzenesulfonic acid, catechol and o-Phenanthroline as its sole carbon resource.

Objective To study the effect of Licofelone,a novel non-steroid anti-inflammatory drug,on the expression of Fractalkine induced by interleukin-18(IL-18) in mesangial cells.Methods Rat mesangial cells were cultured and divided into IL-18 stimulated group,Licofelone-treated group and normal control group.The cells in IL-18 stimulated group were stimulated by 10 ?g/L IL-18 for 24 h.In Licofelone-treated group,ahead of exposure of IL-18 for 24 h,cells were treated with Licofelone in the doses of 10,50 and 100 ?mol/L for 30 min.Additionally,the mesangial cells without treatment of IL-18 and Licofelone were used as normal control group.Reverse transcription-polymerase chain reaction(RT-PCR) was used to measure the level of Fractalkine mRNA.The expressions of Fractalkine protein in every group were detected with enzyme linked immunosorbent assay (ELISA).Results In normal control group,the expression level of Fractalkine mRNA was 179.0?21.0.After exposure of IL-18 for 24 h,the level of Fractalkine mRNA was 1 220.1?185.7,which was higher than that in normal control group (t=9.646 P
