Objective To observe the interference of glucose-6-phosphate dehydrogenase (G6PD) deficiency on glycated hemoglobin (HbA1c) detected by three measurement systems.Methods A total of 286 cases of blood and serum samples were collected at Zhongshan Hospital of Sun Yat-Sun University from August 2012 to April 2016.The blood samples were divided into healthy control group (122 cases),diabetes group (82 cases),glucose-6-phosphate dehydrogenase deficiency group (61 cases) and diabetes with G6PD deficiency group (21 cases).The levels of HbA1 c were detected by three measurement systems,including Primus Ultra2,Variant lⅡ Turbo 2.0 and Modular P.The results of HbA1c were converted into the estimated average blood glucose concentration (eAG).The values of A eAG-FPG in different groups were calculated and statistical analysis was performed for evaluation of the differences from the three measurement systems.Results The HbA1c results measured by the three systems and AeAG-FPG values in G6PD deficiency group were all lower than healthy control group(all P <0.05).The measured results were similar in both diabetes group and diabetes with G6PD deficiency group.Conclusion G6PD deficiency may cause false H-bA1c results detected by three measurement systems.In the case of HbA1c for evaluating blood glucose control,the interference of G6PD deficiency should be noticed.

Objective To estimate the prevalence of Glucose‐6‐phosphate dehydrogenase(G6PD) deficiency in Zhongshan area . Methods The activity of G6PD in red blood cells was determined by using ultra‐violet rate method for neonates ,couples of child‐bearing age and suspected patients who had clinical symptoms in Zhongshan area from 2012 to 2013 .Results The total detection rate of G6PD deficiency was 4 .37% (1 030/23 595);in male the detection rate was 9 .42% (513/5 447);in female the detection rate was 2 .85% (517/18 148) .Conclusion The incidence of G6PD deficiency were high in Zhongshan area .Therefore ,more attention should be paid to the screening of the disease in neonates and couples of childbearing age so as to reduce the incidence of G6PD defi‐ciency and prevent the complications caused by the disease .

Objective To investigate the Influence of beta-thalassemia minor on four different HbA1c detection systems.Methods All 65 blood samples from March 2014 to August 2014 were collected from Zhongshan Hospital of Sun Yat-sen University , and divided to normal control group ( 40 cases ) , no diabetic group(20 cases) and diabetic group (5 cases) combining with beta-thalassemia minor.The fresh mixed whole-blood samples were used for transferring value-assignment in order to improve the comparability of Bio-Rad variant ⅡTurbo, Primus Ultra2 ,Roche Modular PPI to Bio-Rad Variant Ⅱwhich was NGSP Ⅰlaboratory certificated.The whole-blood concentration of HbA 1c were measured by four detection systems . Differences between normal control group and no diabetic group were compared using the Independent Samples T Test.Then Taking the Primus Ultra 2 as comparable system and others as experimental system ,the HbA1c results from no diabetic group and diabetic group were compared by the standardization NGSP Ⅰlaboratory and statistical techniques of consistency test .Results Compared with Variant Ⅱ detection system, after transferring value-assignment, deviations of Variant Ⅱ, Modular PPI and Variant Ⅱ Turbo were -6%to +6%.The HbA1c testing results from normal control group and no diabetic group had no statistical significance (P>0.05).Linear regression analysis demonstrated that the correlation coefficient of Primus Ultra2 with Variant Ⅱ, Modular PPI, VariantⅡTurbo were 0.995, 0.999 and 0.995, respectively (P<0.01).The percentage deviation of the reference system and experimental system was -6.0% to+6.0%.Conclusion There was no obviously significant influence of beta-thalassemia minor on Bio-Rad Variant Ⅱ,Bio-Rad variant ⅡTurbo,Primus Ultra2,Roche Modular PPI detection systems.

<p><b>OBJECTIVE</b>To evaluate the effects of an exercise-based treatment programme (dyslexia, dyspraxia and attention-deficit treatment, DDAT) on various subtypes of attention-deficit/hyperactivity disorder (ADHD).</p><p><b>METHOD</b>Ninety-one ADHD children with standing balance dysfunction (ADHD-I 43, ADHD-HI 15 and ADHD-C 33) were given DDAT for 6 months, the efficacy of DDAT was evaluated before DDAT, three, six months after the treatment and three month after end of the treatment according to SNAP-IV, before and after the treatment by balancing function test and Conners Parents Rating Scale.</p><p><b>RESULT</b>Inattention subscale scores of ADHD-I, ADHD-HI and ADHD-C before and after the interventions were 1.99 ± 0.34, 0.96 ± 0.31, 2.17 ± 0.31and 1.19 ± 0.45, 0.81 ± 0.28, 1.32 ± 0.37, differences of ADHD-I and ADHD-C were significant (P < 0.05), hyperactivity subscale scores of three subtypes of ADHD were 0.81 ± 0.35, 2.01 ± 0.35, 1.96 ± 0.33 vs.0.45 ± 0.33, 0.79 ± 0.41, 1.10 ± 0.35, there were significant differences as well (P < 0.05). The score of hyperactivity symptom was reduced more compared to that of inattention symptom by the SNAP-IV scale parent forms.

Objective To investigate the diagnostic value of dual-energy CT pulmonary angiography (DE-CTPA) and dual-energy CT lung perfusion (DE-CTLP) in the assessment of pulmonary embolism comparing with pulmonary ventilation-perfusion scintigraphy. Methods Fifty patients suspected of PE (26 males, 24 females) underwent both DE-CTPA, DE-CTLP and pulmonary ventilation-perfusion scintigraphy. The results were compared and the correlation between the intravascular clots in DE-CTPA and the perfusion defects in DE-CTLP was analyzed. The sensitivity, specificity and accuracy of DE-CTLP for PE were assessed according to scintigraphic results which was considered as a "gold" standard. Result ( 1 ) Of 50 cases,920 segments in 46 cases were diagnostable, 4 cases were not included because of the poor image quality. lntravascular clots were found in 262 segments on DE-CTPA and perfusion defects in 266 segments were identified on DE-CTLP, while 268 segments were positive on scintigraphy. (2) The perfusion defects on DE-CTLP were correlated well with the clots on CTPA ( r = 0. 883, P < 0. 01 ). The Dual energy CT Lung perfusion imaging had a good consistence with scintigraphy (Kappa = 0. 940, P <0. 01 ). The sensitivity, specificity, positive and negative predictive value were 96. 2% (279/290), 98.0%(641/654), 95. 5% (279/292) and 98. 3% (641/652), respectively. (3)The radiation dose of DE-CTPA and CE-CTLP scan was(4. 37 ± 0. 47) mSv by using CareDose 4D technique. Conclusion DE-CTPA and CE-CTLP can provide pulmonary vascular morphology and parenchyma perfusion information which are useful and valuable for the diagnosis of PE.
