Objective:To discuss the relationship between heart rate (HR) and heart rate differences (HRD) at different time points in head-up tilt test (HUTT) and the occurrence of postural tachycardia syndrome(POTS) in children and adolescents.Methods:A total of 217 children and adolescents diagnosed as POTS, who complained of syncope or presyncope, were chosen as POTS group (aged 6 to 16 years). During the same period, 73 healthy children and adolescents with matching gender and age were selected as control group.All subjects underwent HUTT from October 2000 to November 2019.Get HR (HR0, HR5, HR10) in baseline, HUTT 5 min and 10 min, HRD (HRD5, HRD10) of HR in HUTT 5 min and 10 min minus HR in baseline.Results:(1) HR5, HR10, HRD5, and HRD10 were higher in the POTS group than those in the control group( P<0.05). (2) Univariate Logistic regression: There was a correlation between HR5, HR10, HRD5, HRD10 and the risk of POTS( P<0.01). (3) Multivariable Logistic regression: For each additional unit of HRD5 and HRD10, the risk of POTS increased by 27% ( OR=1.27, 95% CI1.16 to 1.36) and 28% ( OR=1.28, 95% CI1.20 to 1.38). Conclusion:HR and HRD are related with the occurrence of POTS in children and adolescents, but HR and HRD at different time points of HUTT play the little role on the effect size of the occurrence of POTS.

3 mg/L was significantly worse than in those with hs-CRP≤3 mg/L (18.18%,5.45%;P=0.044,log-rank test). Higher hs-CRP concentration was an independent predictor of death or new vascular event(OR 3.609;95% CI 0.869—14.992;P=0.047).Conclusion Higher hs-CRP concentration in acute phase after ischemic stroke is an independent predictor of death or new vascular event in a year.

Objective To investigate the relationship between findings of proton magnetic resonance spectroscopy(~1H-MRS)and tumor proliferative potential in patents with astrocytoma.Methods Thirty four patients of astrocytomas proved by surgery and pathology were examined by MRI and ~1H-MRS,among them 26 were of grade Ⅰ or Ⅱ(low grade)and 8 of grade Ⅲ or Ⅳ(high grade).Twenty one eases of astrocytomas(17 low-grade and 4 high grade respectively)were homogeneous type.Expression of proliferating cell nuclear antigen(PCNA)was detected by immunohistochemical method of streptavidin- biotin-peroxidase(SP).Results The Cho/NAA and Cho/Cr ratios of high-grade astrocytomas(M=4.895, 4.845 respectively)were significantly higher than those of low-grade astrocytomas(M=2.920, 2.000 respectively)in the 21 homogeneous astrocytomas(Z=-2.597,P=0.009;Z=-2.687,P= 0.007 respectively),and the ratios were found to be significantly correlated to the expression of PCNA(A= 7.880)(r=0.607,P=0.003;r=0.457,P=0.038 respectively).However,the differences of Cho/NAA、 Cho/Cr ratios between the high-grade and low-grade astrocytomas were not significant when 34 cases were included,and no relationship was found between Cho/NAA(M=3.965,2.890 respectively)、Cho/Cr(M= 3.080、1.960 respectively)ratios and the expression of PCNA(A=8.100)(r=0.060,P=0.738;r= 0.125,P=0.480 respectively).Conclusion By measuring the Cho/NAA and Cho/Cr ratios,~1 H-MRS may be a valuable method for presurgical in invo prediction of the malignant degree,tumor proliferative potential and prognosis of homogeneous-type astrocytomas.

Objective To understand the influencing factors of hypertension control,and to provide a theoretical basis for developing intervention measures.Methods A two-stage cluster random sampling method was performed and a total of 1 377 cases and 749 controls in Yuhang District were selected.Univariate and multivariate logistic regression analysis were used.Results The control rate of hypertension was 64. 77%.Hypertension control was related to BMI,course of disease and models of follow-up by univariate logistic regression analysis(P<0. 05 ).The multivariate logistic regression analysis showed that older age (OR =0. 983,95%CI=0. 974 -0. 993 ),male (OR =1. 272,95%CI=1. 053 -1. 535 ), overweight (OR=0. 709,95%CI=0. 576-0. 872),obesity (OR=0. 297,95%CI=0. 210-0. 421)and model of group follow-up (OR=0. 495,95%CI=0. 375 -0. 654)were the major influencing factors.Conclusion The older age,male, overweigt,obesity and model of group follow-up were the major influencing factors.Comprehensive intervention measures should be strengthened so as to improve the control rate of hypertension in community.

OBJECTIVETo evaluate the apparent diffusion coefficients (ADC) in magnetic resonance diffusion weighted imaging with echo-planar technique in depicting the tumor cellularity and grading of astrocytoma.

METHODSThirty-four astrocytoma patients including 18 male and 16 female with age from 10 to 73 years (mean 38.4 years) were examined by MRI and eventually proved by surgical resection and pathological examination. Of them, 26 had low-grade (grade I, II) astrocytoma and 8 high-grade (grade III, IV) astrocytoma. ADC value of astrocytoma was determined on magnetic resonance diffusion weighted images. Cellularity of the astrocytoma was analyzed using Adobe Photoshop 7.0.1 software.

RESULTSThe mean ADC value (in units of 10(-4) mm(2)/s) of the high-grade astrocytomas (7.34 +/- 2.95) was significantly lower than that of the low-grade astrocytomas (13.76 +/- 3.31) (t = 4.91, P < 0.001). The mean cellularity of the high-grade astrocytomas (19.81 +/- 9.73)% was significantly higher than that of the low-grade astrocytomas (4.74 +/- 2.96)% (t = 4.32, P = 0.003). ADC value of the astrocytoma was significantly and negatively correlated with its cellularity (r = -0.535, P = 0.001).

CONCLUSIONADC value of astrocytoma is significantly and negatively correlated with its cellularity. Magnetic resonance diffusion weighted imaging may well be highly potential in predicting the degree of astrocytoma.

The aim of this study was to investigate the similarities and differences of A1381T (rs216311) and -1793G/C (rs7966230) single nucleotide polymorphisms (SNP) in Chinese Yugur, Tibetan, and Han nationalities and their influence on plasma vWF concentration in order to explore the sensitivity of these 3 nationalities to vWF-related diseases. Peripheral venous blood was obtained from 322 Yugur, 399 Tibetan, and 120 Han healthy people. The DNA were then extracted. vWF gene A1381T and -1793G/C polymorphisms were analyzed by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequenced when it was necessary. The vWF:Ag level in plasma was determined by ELISA. The results showed that the genotype distribution of vWF gene at both A1381T and -1793G/C loci in Yugur, Tibetan and Han nationalities was different with statistically significance (P < 0.05). GG genotype of A1381T locus accounted for 69.9% in Yugur nationality, which was much higher than 56.6% and 53.3% in Tibetan and Han nationalities respectively(P < 0.01); AA genotype of A1381T locus expressed a low level of vWF in plasma. For the -1793G/C locus, the proportion of CG genotype in Yugur was much higher than that in Han, CC genotype expressed a high level of vWF in plasma. The plasma vWF levels with different nationalities and the polymorphism of vWF gene were significantly different. It is concluded that the polymorphisms of vWF gene at both A1381T and -1793G/C loci in Yugur, Tibetan and Han are significantly different; the polymorphism of vWF gene influences the plasma vWF level; the plasma vWF levels in Yugur and Tibetan are significantly higher than that in Han, which may be associated with the living environment and habits.
