Objective To investigate the impact of umbilical cord around the neck(UCAN) on infants developmental quotient. Methods Intelligence of 60 infants of UCAN under 3 years old were tested by Gesell. Results DQ of UCAN infants was significantly less than normal infants,mainly mild to moderate retardation. DQ between the male and female infants had no significant difference, parents' cognitive level had significant difference with real DQ of infants. Conclusions UCAN has certain influence on mental development of infants,we should strengthen health education,pay close attention to UCAN infants,give regular intelligence surveillance, find early growth retardation,give rehabilitation training to reduce the incidence of intellectual disabilities.

Objective To observe the effect of Guanxin Ⅱ Hao on plasma NO and NOS in dog with myocardial ischemia. Methods 20 dogs of myocardial ischemia were divided into the control group, isosorbidi mononitratis group and the Guanxin Ⅱ Hao group by random. The NO and NOS of serum were measured, before and after treatment. Results In the control group, the level of NO and NOS were higher than that of the isosorbide mononitrate group. There was significant difference between the control group and the Guanxin II Hao groups (P

Objective To evaluate clinical application of VCS technology in diagnosis for acute leukemia and its subtypes by LH750 automated hematology analyzer. Methods A total of 178 leukemia patients (105 acute granilocytic leukemia, 42 acute lymphocytic leukemia, 31 acute monecytic leukemia)and 151 non-leukemia patients (86 granulocytic abnormal cases, 35 lymphocytic abnormal cases,30 monocytic abnormal cases) were enrolled into this study. Peripheral blood samples were analyzed by both Coulter LH750 automated hematology analyzer and manual microscopic examination. Microscopic examination was used as reference to evaluate the diagnosis value of VCS technology in blast detecting. VCS parameters were compared for AGL subsets. The clinical value of VCS technology in diagnosis for different acute leukemia was also evaluated by combining VCS scattergram and suspect flags provided by LH750. Results Compared with manual examination, a sensitivity of 95.5% (170/178) and specificity of 95.4% (144/151) were achieved by VCS technology in detecting blasts in acute leukemia and nonleukemia patients. In patients with AGL, the MNV, MNV-SD, MNC and MNC-SD (224.40 ± 23.37,37.40 ±12. 31,145. 80 ±7. 93,24. 79 ±5. 18) were higher than granulocytic abnormal patients( 169.96 ±11.50,29.21 ± 5.27,133.30 ± 5.50, 10.62 ± 4.09) and the differences were statistically significant ( t values were 16. 832, 5. 148, 5. 735, 19. 953 respectively, P < 0. 01 ). On the contrary, MNS ( 122. 90 ±6. 35) in AGL patients was significantly lower than granulocytic abnormal patients( 131.00 ± 5. 69, t =-7.64, P<0.01). In patients with ALL, the MLV, MLV-SD, MLC, MLS, MLS-SD (97.60 ± 13.40,22. 35 ± 7.94,110. 00 ± 4. 60,77. 60 ± 19.00,20. 61 ± 3.30 ) were higher than lymphocytic abnormal patients(82. 10 ± 3.00, 14.41 ±2.35, 100.60 ±2.70, 48. 10 ±3.50, 17.60 ± 1.60). The data also showed a statistical significance (t values were 7.576, 6. 118, 4. 041, 9. 353, 2. 988 respectively, P <0.05). In patients with AMOL, the MMV, MMV-SD, MMC, MMC-SD, MMS(197. 30 ±20.50,30.47 ±6.58,123.20 ± 10. 10,6.57 ± 1.57,98.00 ± 5.60) were significantly higher than monocytic abnormal patients( 167.80 ± 15.77,21.90 ± 9. 64,113.60 ± 6. 73,5.20 ± 3. 21,84. 20 ± 14. 35 ) and the differences were statistically significant (t values were 6. 332, 4. 033, 4. 650, 2. 993, 6. 273 respectively , P <0. 01 ).The differences of MNV, MNV-SD, MNC, MNC-SD, MNS-SD for different AGL subtypes were statistically significant ( F values were 21.2, 169. 5, 13.6, 3. 6 and 98.6 respectively, P <0. 01 ). For AGL, ALL and AMOL, the ratios of normal blast distribution in scattergram were 81% (85/105), 74% (31/42) ,and 74% (23/31). Conclusions The VCS parameters can reflect the changes of peripheral white blood cell morphology sensitively. VCS technology can diagnose acute leukemia and its subtypes efficieutly.

Objective To investigate the expression of human epididymal protein 4 (HE4) in chronic kidney disease (CKD) and its clinical value.Methods From April 2014 to December 2015,Serum samples of 92 non-cancer patients diagnosed as CKD and 84 healthy controls were collected in Nantong University Hospital.HE4,BUN,Scr,Cys C and β2MG were detected.The difference of HE4 expression in different stages of CKD and the correlation of HE4 with Urea,Scr,Cys C and β2MG were analysized,respectively.ROC curve was used to evaluate the auxiliary diagnostic value of HE4,BUN,Scr,Cys C and β2MG.Results The serum HE4 expression in patients with impaired renal function was 388.2 (130.1～1 659.5)mIu/ L,(F=16.237,P=0.001).Which was significantly higher than that in the control group [38.1 (32.77 ～ 48.17)mIu/L].The serum HE4 expression was increased by the stage of renal damage and the difference was existed among different groups (P＜0.05).HE4 expression was positive related with Cys C and β2MG.The AUC of HE4,BUN,Scr,Cys C and β2MG were 0.878,0.785,0.816,0.874 and 0.819,respectively.Conlusion It needs to consider the exsits of impaired renal function when the HE4 was detected.The HE4 might be a novel early diagnostic indication for CKD.

0.05). The positive rates of MMP-2 and MMP-9 were significantly higher in the cases with lymphnode metastasis [84.72% (61/72) and 77.78% (56/72)] than those without lymphnode metastasis [50% (4/8) and 37.50% (3/8), P

Objective To study the seasonal changes of glucose levels per unit soft tissue of Oncomelania hupensis. Meth-ods O. hupensis snails were collected from the beach of the Qingyi River in Wuhu City,Anhui Province from August 2012 to July 2013. They were kept in minus 80℃refrigerator immediately. The male snails were distinguished from female,and their soft tissues were collected separately after crushing their shells. The hexokinase method was used to measure the glucose concen-trations,and the results were analyzed statistically. Results The contents of glucose decreased from March to July. The lowest glucose content in the female was 1.87μg/mg in March,and that in male was 3.70μg/mg in July. Both of them increased from August and reached peak levels in September(♀=57.38μg/mg,♂=44.39μg/mg),and then gradually decreased from Octo-ber to next January and increased in February. Conclusion The contents of glucose have seasonal changes regularly in O. hu-pensis.

Objective To assess the feasibility of computed tomography angiography (CTA) in renal artery using the iterative reconstruction technique (iDose4) in Brilliance iCT (Philips Ltd.).Methods 90 patients (body weight 60-70 kg) supposed to undergo renal artery CTA were selected and randomly divided into three groups:A(120 kV,120 mAs),B(120 kV,60 mAs) and C(100 kV,100 mAs).CTA images from Group A were obtained using filtered back projection and those from the rest groups were generated by iDose4.Then CT number of renal artery,noise (denoted as standard deviation SD),signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of images for each group were measured and recorded.Images were post-processed using volume reformation (VR) 3D imaging and image quality were assessed in five-level grade (1-5).Results The five parameters (CT number of renal artery,SD value,SNR,CNR and VR grade) of group A and group B were statistically insignificant (P ＞ 0.05).While SD values of group C were comparable to those of group A and B,the rest four parameters of group C were apparently larger,which was statistically significant (tCT value =-12.326,tSNR =-7.136,tCNR =-7.649,ZVR =-2.690,PVR ＜ 0.05).Conclusions Image quality could still fit the diagnosis requirements using iDose4 when mAs decreased lower than 50％.The image quality increases when radiation dose is halved at 100 kVp kV.
