It is of great significance to study how temperature affects the restricted diffusion in pores for an accurate evaluation of reservoir physical properties by using nuclear magnetic resonance(NMR)diffusion-transverse relaxation(D-T2)spectrum under reservoir temperature *** this paper,we simulate the restricted diffusion and twodimensional(2D)NMR D-T2 spectra of water molecules at different temperatures using random-walk *** one-dimensional(1D)restricted diffusion simulation results show that the diffusion coefficient in the pore at room temperature decays with the diffusion time and eventually reaches a *** the condition of long-time diffusion,the ratio of restricted diffusion coefficient to bulk diffusion coefficient at different temperatures tends to be the same *** the increase in temperature,the simulated D-T2 spectra also gradually move *** simulated D-T2 spectra at all temperatures are consistent with the Pade interpolation *** addition,the results calculated by Pade interpolation equation demonstrate that the degree of temperature influence on the D-T2 spectrum of rock is quantitatively related to the pore radius,porosity and cementation index.

Human beings keep exploring the physical space using information means. Only recently, with the rapid development of information technologies and the increasing accumulation of data, human beings can learn more about the unknown world with data-driven methods. Given data timeliness, there is a growing awareness of the importance of real-time data. There are two categories of technologies accounting for data processing: batching big data and streaming processing, which have not been integrated well. Thus,we propose an innovative incremental processing technology named after Stream Cube to process both big data and stream data. Also, we implement a real-time intelligent data processing system, which is based on real-time acquisition, real-time processing, real-time analysis, and real-time decision-making. The real-time intelligent data processing technology system is equipped with a batching big data platform, data analysis tools, and machine learning models. Based on our applications and analysis, the real-time intelligent data processing system is a crucial solution to the problems of the national society and economy.

目的:探讨1型糖尿病(T1DM)患者全孕程持续葡萄糖监测(CGM)参数及产前血糖水平与新生儿低血糖发生的相关性。方法:本研究为多中心、前瞻性、观察性队列研究,自2015年1月至2017年12月在全国11家医院招募T1DM合并妊娠患者作为研究对象,采用CGM监测孕期血糖,记录产前2 h毛细血管血糖和新生儿结局。本研究纳入完成全孕程CGM的T1DM患者73例,根据分娩后新生儿血糖值(新生儿低血糖定义为新生儿血糖7.8 mmol/L、TAR 2>13.9 mmol/L)、葡萄糖低于目标范围时间(TBR)、血糖标准差(SDBG)、平均血糖波动幅度(MAGE)、变异系数(CV)]、产前2 h血糖水平、分娩时孕周以及新生儿结局[出生体重、出生身长、早产率、新生儿重症监护病房(NICU)入住率]的差异。组间比较采用独立样本 t检验、秩和检验、 χ^(2)检验和Fisher精确检验法。采用多因素logistic回归模型分析新生儿低血糖发生的影响因素。结果:相较新生儿血糖正常组,新生儿低血糖组孕母孕早期日间平均血糖[分别为(6.91±0.71)和(6.38±0.81)mmol/L, t=2.041, P<0.05]、孕早期TAR 2[分别为0.81%(0,4.36%)和0(0,0.64%), Z=2.064, P<0.05]、孕早期MAGE[分别为(6.42±3.24)和(4.60±1.67)mmol/L, t=2.137, P<0.05]、产前2 h血糖水平[分别为(7.75±2.22)和(6.13±2.10)mmol/L, t=2.324, P<0.05]升高,差异均具有统计学意义。新生儿低血糖组的早产率[分别为35.71%(5/14)和11.86%(7/59), χ^(2)=4.686, P<0.05]和NICU入住率[分别为71.43%(10/14)和32.20%(19/59), χ^(2)=5.725, P<0.05]高于新生儿血糖正常组,差异均具有统计学意义。多因素logistic回归分析提示,孕母产前2 h血糖是新生儿低血糖的独立影响因素(OR=2.23,95%CI 1.09~4.54, P<0.05)。结论:T1DM患者孕早期平均血糖、TAR和MAGE与新生儿低血糖的发生相关,产前2 h血糖水平与新生儿低血糖的发生独立相关。

In this population-based study, we identified 307 confirmed COVID-19 cases from massive surveillance,including 129 551 individuals screened at fever clinics or returning from Hubei and 3710 close contacts of confirmed COVID-19 patients. Among them, 17 patients were asymptomatic at initial clinical *** asymptomatic patients on admission accounted for a small proportion of all patients(5.54%) with relatively weak transmissibility, and the detection rate was 0.35 per 100 close contacts. Moreover, the dynamics of symptoms of the 307 patients showed that the interval from symptom remission to the final negativity of viral nucleic acid was 5.0 days(interquartile range 2.0 to 11.0 days), with 14 patients(4.56%)having re-detectable viral RNA after discharge. Overall, our findings suggested asymptomatic carriers and presymptomatic patients only accounted for a small proportion of COVID-19 patients. Also, the asymptomatic phase during recovery from COVID-19 implied that negativity in viral RNA is necessary as a de-isolation criterion and follow-up is recommended.

目的探讨使用智能手机应用程序(APP)对妊娠期糖尿病(GDM)患者进行孕期院内外综合管理对其孕期血糖水平及妊娠结局的影响。方法为回顾性队列研究,选取2022年1至12月于中国科学技术大学附属第一医院产科分娩并注册我国首个GDM院内外管理互联网服务平台——糖妈妈APP的GDM患者为研究对象,计算其注册APP到完成当次分娩时间段内的APP总体使用活跃度(由血糖监测频率、线上沟通频率、课程学习频率总和组成),并基于此结果将GDM患者分为高活跃度组和低活跃度组。收集研究对象年龄、教育程度、控糖方式、产次,体重和身高并计算孕前体重指数(BMI),糖化血红蛋白(HbA_(1c))并计算HbA_(1c)达标率(HbA_(1c)<6%),孕产妇结局[妊娠期体重增加(GWG)、剖宫产],新生儿结局[大于胎龄儿(LGA)、巨大儿、新生儿高胆红素血症]及新生儿住院费用。采用两独立样本t检验、Mann-WhitneyU检验、卡方检验和Fisher精确检验进行组间比较,采用logistic回归模型分析APP总体使用活跃度对不良妊娠结局的影响。结果共纳入GDM患者616例。其中,高活跃度组308例,低活跃度组308例。与低活跃度组相比,高活跃度组GDM患者孕晚期HbA1c较低[分别为(5.6±0.4)%和(5.5±0.4)%,t=-2.341,P=0.020],孕晚期HbA1c达标率较高[分别为81.1%(154/190)和89.9%(186/207),χ^(2)=6.243,P=0.012],GWG较少[分别为(12.7±5.7)和(11.1±5.7)kg,t=-3.469,P=0.001];高活跃度组剖宫产[分别为53.9%(166/308)和45.1%(139/308),χ^(2)=4.734,P=0.030]、LGA[分别为23.1%(71/308)和11.7%(36/308),χ^(2)=13.855,P<0.001]、巨大儿[分别为14.3%(44/308)和8.8%(27/308),χ^(2)=4.601,P=0.032]及新生儿高胆红素血症[分别为14.9%(46/308)和9.1%(28/308),χ^(2)=4.976,P=0.026]发生率较低,新生儿住院费用较少[分别为5740.0(4465.8,7292.6)元和5304.9(4219.0,5901.2)元,Z=-2.383,P=0.017]。logistic回归分析结果显示,校正孕妇年龄、孕前BMI、教育程度、控糖方式、产次后,GDM患者APP总体使用活跃度高是孕晚期HbA1c达标率增加(OR=2.20,95%CI 1.17~4.12,P=0.014),以及LGA(OR=0.43,95%CI 0.27~0.68,P<0.001)及巨大儿(OR=0.59,95%CI 0.35~0.99,P=0.044)、新生儿高胆红素血症发生率降低(OR=0.56,95%CI 0.34~0.93,P=0.025)的影响因素。结论糖妈妈APP的使用频率增加与GDM患者孕期血糖水平降低和不良妊娠结局风险降低有关。
