Objective To measure von Willebrand factor(vWF)concentrations and von Willebrand factor-cleaving protease(vWF-cp)activity in plasma of lung cancer patients and to evaluate their clinical significance.Methods The vWF:antigen(vWF:Ag)and vWF-cp activity were measured by using ELISA and residual-collagen binding assay(R-CBA),respectively in 78 patients with lung cancer.The serum and pleural fluid(PLF)of carcino-embryonic antigen(CEA)were measured by radioimmunity assay in 23 patients.Results (1)The level of vWF:Ag in lung cancer patients(107.7?43.7)%was significantly higher than that in benign diseases(71.3?49.5)% and normal controls(82.4?41.3)%(P

Objective To investigate the neuromuscular blocking effects and clinical pharmacology of different dosage of mivacurium chloride in infants during sevoflurane anesthesia. Methods Forty ASA I infants undergoing sevoflurane general anesthesia were randomly assigned to tow groups according to the dose level of mivacurium: group1: 200 μg/kg ( n =20) and group2: 250 μg/kg ( n =20) . TOFs were determined synchronously. The onset time of mivacurium, recovery time of spontaneous breathing and cardiovascular reactions were measured. Results The onset time was significantly shortened in group 2 compared with group 1 (P<0.05) . There was no significant difference in the recovery time of spontaneous breathing between the two groups. 2 minutes after mivacurium was injected, DBP in group 2 decreased significantly compared with baseline and group 1. 3 minutes after mivacurium was injected,SBP in group 2 decreased significantly compared with baseline and group 1. Conclusion In infants undergoing sevoflurane general anesthesia, the onset time of mivacurium can be shortened when 250μg/kg was administered,but the depression of cardiovascular system may occurr simultaneously.

Objective To analyze the predictive value of N-terminal B-type natriuretic peptide precursor(NT-proBNP) on auricular thrombosis in patients of coronary heart disease (CHD) combined with atrial fibrillation (AF).Methods The clinical data of 124 patients of CHD combined with AF were analyzed retrospectively.All patients were divided into research group (60 cases,compliance with auricular thrombosis) and control group (64 cases,non-compliance with auricular thrombosis),according to the occurrence of auricular thrombosis.The values of NT-proBNP,fasting plasma glucose (FPG),postprandial plasma glucose(2 h PG),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C),oxidized low density lipoprotein (ox-LDL),high sensitivity C reactive protein (hs-CRP) and left ventricular ejection fraction (LVEF),left ventricular end diastolic diameter (LVEDd) and left atrial diameter (LAD) were detected and compared between two groups.The relative factors to the occurrence of auricular thrombosis were confirmed by multivariate Logistic analysis.The best cutoff point of NT-proBNP was confirmed by the areas under the receiver operating characteristic curve (ROC).Results The values of NT-proBNP,ox-LDL,hs-CRP,LVEDd and LAD in research group were higher than those in control group [(4 312.6 ± 209.1) pmol/L vs.(3 421.6 ± 156.8) pmol/L,(4.0 ± 0.9) mmol/L vs.(3.4 ± 0.8) mmol/L,(7.4 ± 1.3)mg/L vs.(5.8 ± 1.0) mg/L,(74.3 ± 6.8) mm vs.(58.1 ± 5.5) mm,(39.6 ± 4.3) mm vs.(32.5 ± 3.8) mm],LVEF and HDL-C were lower than those in control group [(48.2 ± 3.1)％ vs.(57.3 ± 3.8)％,(0.72 ± 0.16)mmol/L vs.(1.08 ±0.27) mmol/L],and there were significant differences (P ＜0.05).There were no significant differences in the values of FPG,2 h PG and TC between two groups (P ＞ 0.05).Multivariate Logistic analysis showed that NT-proBNP and LAD were independent factors to the occurrence of auricular thrombosis (P =0.009,0.028).There was significant difference in the occurrence of auricular thrombosis between patients with NT-proBNP ＞ 4 250 pmol/L and patients with NT-proBNP≤4 250 pmol/L (P =0.028).Conclusion NT-proBNP is an independent predictor for the occurrence of auricular thrombosis to patients of CHD combined with AF.

With the development of therapeutic antibodies over the past decade, they have become the treatment options for immunity and inflammation diseases. Major limitations of mouse antibodies as therapeutic agents - immunogenicity, lack of effectors' functions and short serum half-life -- were subsequently identified and largely overcome by the advent of humanized and fully human antibody technologies. The therapeutic antibodies for immunity and inflammatory diseases are primarily utilized in the treatment of allograft rejection, autoimmune disease, autoinflammatory syndromes, allergies and other chronic inflammation. The action mechanisms of therapeutic antibody include blocking ligands or receptors, regulating receptor activity, clearing the target cells or activating receptor. Strategies for generating the antibody drugs with high efficacy and low side effects can be realized by modulation of Fc-mediated activities and optimization of antigen-binding domains.

BACKGROUND:Because the geographical environment and diet cause obesity and osteoarthritis in Xinjiang Uygur local patients, the number of patients became more. At present, more and more patients received artificial knee replacement. How to master and further apply the technology of soft tissue balance during artificial knee replacement in patients of different physical fitness and nations becomes the focus of many scholars. OBJECTIVE:To analyze the clinical efficacy of soft tissue balance in Xinjiang Uygur patients with knee valgus in total knee replacement. METHODS:A total of 60 cases (72 knees) with severe knee osteoarthritis with a certain degree of knee valgus were subjected to total knee replacement through anterior lateral approach and individualized soft tissue balance from February 2009 to December 2010. Folow-up mode was the clinic visit. X-ray was used to measure tibiofemoral angle (i.e., the supplementary angle of the included angle between anatomic axis of femur and tibia). Clinical score and functional score of American knee society knee score were applied to assess knee joint function. RESULTS AND CONCLUSION:A total of 57 patients were folowed up for 6-35 months. The tibiofemoral angle decreased from 27.9° preoperatively to 5.6° postoperatively. Clinical score of American knee society knee score elevated from 16.7 points preoperatively to 87.5 postoperatively. Functional score of American knee society knee score elevated from 7.9 points preoperatively to 85.2 postoperatively. Significant differences in preoperative and final folow-up scores were detected (P < 0.01). Valgus deformity was corrected and joint stability was good in 57 patients after replacement. These findings indicate that in patients with severe knee osteoarthritis and valgus deformity, to select individualized treatment of soft tissue balance can effectively correct soft tissue imbalance and get more satisfactory clinical results.
