significant for the precaution of gastric cancer risk population. Aims:To explore gastric cancer susceptibility gene profiling in an area in Shanghai,and to assess the risk of gastric cancer susceptibility. Methods:A total of 152 patients with primary gastric cancer at Shanghai Pudong Hospital were enrolled,and 152 demographic characteristics matched patients with non-gastrointestinal diseases,non-tumor were served as controls. Gene polymorphism was determined by allele specific polymerase chain reaction. Susceptibility gene of gastric cancer was screened. Multiple genes interactions were analyzed and multiple genes risk was evaluated by DEMCHUK model. Results:Univariate analysis showed that CYP2E1,NAT2M1,NAT2M2,NAT2,XRCC1194,MTHFRA1298C,VDR TaqⅠ were susceptibility genes of gastric cancer. Multivariate analysis showed that CYP2E1(C1/ C1),NAT2M1(T/ T),NAT2M2(A/ A),XRCC1194( T/ T)and MTHFRA1298C(A/ C)were susceptibility genotypes. Synergistic effect was found between genes except MTHFRA1298C (A/ C)with NAT2M1(T/ T)and NAT2M2(A/ A)(P ﹤0. 05). Multiple genes risk analysis showed that combination OR of multiple genes was highly correlated with gene frequency,and the risk of gastric cancer was increased with the increasing number of susceptibility genes. Conclusions:CYP2E1(C1/ C1),NAT2M1(T/ T),NAT2M2( A/ A),XRCC1194( T/ T) and MTHFRA1298C( A/ C) are susceptibility genotypes of gastric cancer. Carrying multiple susceptibility genes can significantly increase the risk of gastric cancer.

Objective Toexplore the correlation of ApoE gene polymorphism and serum uric acid levels in Ningxia Hui Autonomous Region , China.Methods A case-control study.October 2011 to November 2011, five hundred twenty eight ( 296 male, 232 female ) apparently healthy individuals were studied.Questionnaires and physical examinations were performed by standard operation procedure.Fasting blood was collected for biochemistry testing including serum lipid parameters , uric acid concentration and creatinine levels.The multi-ARMS PCR was applied to determine ApoE genotypes ,and the relation of ApoE genotypes with serum lipid parameters and uric acid levels were analyzed.Non-normal distribution were compared using cause and inspection.Results The common six kinds of ApoE genotype can be detected.The total cholesterol ( TC) ,low density lipoprotein cholesterol ( LDL-C) and uric acid ( UA) levels in different genotype subgroups had statistical differences.The individuals with ε2/3 genotype had a significantly greater reductions in TC and LDL-C levels but increment in uric acid concentration than those withε3/3 and ε3/4 genotype (P<0.05).The effect of ApoE gene polymorphism on uric acid levels still remained significantly after adjustment for age , gender , region and other factors.Conclusion The ApoE polymorphism is associated with serum uric acid levels and individuals with ε2 allele have higher serum uric acid levels.

Objective To investigate the interference of thyroglobulin antibodies ( TgAb ) on the measurement of thyroglobulin ( Tg) by 2 chemiluminescence immunoassays ( CLIAs) .Methods Data of 199 315 individuals with determined TgAb and Tg , including physical checkup subjects , differentiated thyroid carcinoma ( DTC) patients and patients with other diseases , were retrospectively collected in Peking Union Medical College Hospital from November 2012 to April 2015.The correlation between serum Tg level and serum TgAb concentration was analyzed and the positive rate of TgAb in physical checkup subjects was calculated.Furthermore, 290 serum samples with different TgAb concentration were applied in the recovery test by adding in confirmed serum Tg .The correlation between the recovery of confirmed serum Tg and TgAb concentrations was evaluated using Pearson correlation analysis .Results The serum Tg was all decreased with the elevated TgAb concentration in each group of subjects .The positive rate of TgAb was 10.84%(8 416/77 634) in physical checkup subjects .It was higher in females than in males and was increased with age.Recovery test showed that the average recoveries of confirmed serum Tg in TgAb-negative serum were 107.28%(86.30%-117.60%) and 107.94% (85.60%-124.10%) respectively in Roche and Beckman systems.But in TgAb-positive serum samples , the average recoveries in Roche and Beckman systems were 88.59% (35.85% -141.53%) and 95.77% (36.48% -131.78%) respectively, and 12.63%(24/190) and 13.68%(26/190) samples displayed a recovery less than 80%.The recovery rate of confirmed serum Tg showed a significantly negative correlation with elevated TgAb concentration , with r=-0.239 (P=0.001) in Roche and r=-0.251 (P<0.001) in Beckman.Conclusions TgAb-positive serum, especially with high concentration of TgAb , significantly interfered the measurement of Tg .Thus, serum TgAb should be determined together with serum Tg to explore whether there was an interference .To avoid misdiagnosis and inappropriate therapy , clinician should be informed once serum TgAb displayed positive.

Objective To validate the performance of six enzymatic glycated albumin reagents and evaluate their clinical application.Methods The performance of six enzymatic glycated albumin reagents(labled as A,B,C,D,E,F) from Beijing Jiuqiang Co, Beijing Lideman Co,Ningbomeikang Co, Beijing Haomai Co, Sichuan Maike Co and Asahi Kasei Co were assessed on Olympus AU5800 automatic biochemistry analyzer.According to the standard of CLSI,the precision,interference and linear correlation of these reagents were assessed.To assess the accuracy of GA% ,we used GA standard material whose value had been assigned using ID-LC/MS method provided by ReCCS.To do the method comparison and determine the consistency of assay, 50 fresh serum samples of T2DM outpatient and 80 fresh serum samples of apparently healthy people in Jan 2016 were tested using six kits.According to the EP28-A3C protocol, the reference range for GA%was validated in 122 apparently healthy individuals undertaking medical examination from January to February 2016 in PUMC.Results The precision,and the ability of anti-interference of the six reagents were good.The accuracy percentage deviation of six reagents was-19.3%-9.2%.The correlation coefficient of domestic reagents A to E and imported reagents F in the determination of GA% was 0.966-0.999, the average absolute bias was 7.0%-10.4%.The coincidence rate of A-E and F in determining abnormal GA% was between 88.5% and 96.9%.The coincidence rate was increased after switching to the reference range for preliminary clinical evaluation.Conclusion Six GA enzymatic kits used in automatic biochemical analyzer have high precision and strong anti-interference ability.Accuracy still needs to be improved.

Objective To assess the interference by calcium dobesilatein 7 peroxidase-baseduric acid assays and to determine its clinical significance.Methods In the in vitro experiments, uric acid in pooled serum with final concentrations of calcium dobesilate additions (0, 2, 4, 8, 16, 32, and 64μg/ml) were measured by 7 peroxidase-based assays.Percent Bias (%) was calculated relative to the drug-free specimen.In the in vivo experiments, changes in serum uric acid and calcium dobesilate concentrations were observed before and after calcium dobesilate administration ( baseline, 0 h, 1 h, 2 h, 3 h, 4 h, 6 h ) involunteers.The interference in different assays was assessed compared with LC-IDMS/MS method. Calcium dobesilate levels in 40 specimens from those taking calcium dobesilate were measured by HPLC method.Of the 40 specimens, 10 were selected to analyse the levels of uric acid by both peroxidase and UV measurement method to assess the impact in clinical status.Results In the in vitro study, concentrations of uric acid measured by 7 peroxidase-based assays were reduced by -6.3%to -21.2%compared with drug-free serum, when theconcentration of calcium dobesilate was16μg/ml.In the in vivo study, comparedto UA levels at 0 h, the biasesof serum uric acid determined by peroxidase method after calcium dobesilate administration(1 h, 2 h, 3 h, 4 h, 6 h) were of -3.33%, -6.79%, -7.49%, -6.07%, -4.09%, respectively.The observed uric acid concentrations for 8 participants measured by enzymatic assays were inhibited by -3.75% to -6.89% at 0 hour and by -16.9% to-22.22% at 2 hours relative to the concentrations measured by the LC-IDMS/MS method. Conclusions Calcium dobesilate produced a clinically significant negative interference with uric acid in all peroxidase-based uric acid assays,which may result in false evaluation of uric acid level in clinical status.Significant differences in the degree of interference were observed among the assays.

Objective To evaluate the effects of different sedation depths of propofol on postopera-tive delirium in patients undergoing cardiac valve replacement under cardiopulmonary bypass(CPB)and the relationship with regional cerebral oxygen saturation(rSO2). Methods Forty American Society of An-esthesiologists physical statusⅢorⅣpatients of both sexes, aged 26-64 yr, with body mass index of 17-25 kg∕m2, scheduled for elective aortic valve replacement with CPB, were divided into A and B groups (n=20 each)using a random number table. The infusion rate of propofol was adjusted to maintain the cor-responding anesthetic depth with 50≤BIS value<60 during CPB in group A and with 35≤BIS value<45 during CPB in group B. Bilateral rSO2was measured using the near infrared spectroscopy from admission to the operating room until the end of skin suturing. The minimum rSO2was recorded, and occurrence of low cerebral oxygen saturation(rSO2was less than 55% or the decrease in rSO2>20% of the baseline)was ob-served. Postoperative delirium was evaluated using Confusion Assessment Method for the Intensive Care Unit (ICU)from 12 h after admission to ICU until discharge from ICU. Results The incidence of postoperative delirium, low cerebral oxygen saturation and minimum rSO2were significantly lower in group B than in group A(P<005). Conclusion Maintaining 35≤ BIS value< 45 during CPB can reduce the develop-ment of postoperative delirium and is related to improving intraoperative rSO2in patients undergoing cardiac valve replacement.
