【目的和方法】富油煤原位热解产生的油、气在高温作用下会通过煤层顶板的裂隙带向覆岩层迁移富集,给地下环境造成潜在污染风险。为了了解富油煤地下热解过程中典型污染物的释放与分布特征,以陕北侏罗纪煤田神府矿区典型富油煤为研究对象,基于研究区地层结构与岩性资料,采用自主研发的富油煤原位热解相似模拟实验装置,研究富油煤热解产物的组成,及不同温度下煤焦油中酚油、萘油、洗油、蒽油和沥青等典型污染物的时空分布特征。【结果和结论】结果表明:不同热解温度下,典型污染物在覆岩中的分布随时间增加均呈现先上升后下降的趋势,且各组分含量与富集层位差异较大。热解温度为450℃和650℃下,不同覆岩层中污染物含量大小排序为沥青>蒽油>萘油>洗油>酚油。在450℃时,由于温度较低对覆岩层影响相对较小,所以各组分主要富集在中粒砂岩层。随着温度不断升高,覆岩层产生裂隙,导致650℃时轻质组分富集在距煤层较远的泥岩层,重质组分由于密度大且黏性强,迁移能力较差,所以其主要富集区域为泥质粉砂岩层。温度是影响覆岩中典型污染物时空分布特征的主要因素,升高温度会增加污染物的迁移范围,并且酚油、萘油和洗油含量的占比随之逐渐增大,蒽油和沥青含量的占比随之逐渐减小。研究结果为富油煤原位热解地下污染管控提供理论依据。

塔河油田石炭系卡拉沙依组是碎屑岩油气勘探的重要领域,但对于其沉积环境及相类型的划分一直存在争议,一定程度上制约了油气勘探。为揭示塔河油田石炭系卡拉沙依组沉积环境及砂体的分布规律,本文以层序地层学和沉积学理论为指导,利用钻井、测井、岩心等资料进行研究分析,系统刻画了卡拉沙依组的沉积特征。结果表明:(1)塔河油田卡拉沙依组兼具辫状河三角洲和潮坪沉积特征,识别出分流河道、水下分流河道、河口坝、潮汐水道、砂坪、砂泥混合坪、泥坪7种沉积;(2)从平面展布上来看,研究区北部以辫状河三角洲相为主,南部以潮汐沉积为主,中部发育大量受潮汐改造的水下分流河道;(3)海退时期研究区沉积主要受河流控制,水下分流河道规模较大;海进时期主要受潮汐作用控制,潮道规模较大。在此基础上,建立了塔河油田石炭系卡拉沙依组缓坡背景下受潮汐影响的辫状河三角洲纵向分布相带序列模式和河控—潮控沉积模式,可为该层段下一步勘探工作提供参考依据。

Effect of dexamethasone on intelligence and hearing in preterm infants: a meta-analysis

引用

Neural Regeneration Research 2014年第6期9卷 637-645页

作者： ruolin zhang Tao Bo Li Shen Senlin Luo Jian Li Department of Pediatrics Second Xiangya Hospital Central South University

OBJECTIVE： A meta-analysis of published randomized controlled trials investigating the long- term effect of dexamethasone on the nervous system of preterm infants. DATA SOURCES： Online literature retrieval was conducted using The Cochrane Library （from January 1993 to June 2013）, EMBASE （from January 1980 to June 2013）, MEDLINE （from Janu- ary 1963 to June 2013）, OVID （from January 1993 to June 2013）, Springer （from January 1994 to June 2013） and Chinese Academic Journal Full-text Database （from January 1994 to June 2013）. Key words were preterm infants and dexamethasone in English and Chinese. STUDY SELECTION： Selected studies were randomized controlled trials assessing the effect of intravenous dexamethasone in preterm infants. The quality of the included papers was evaluated and those without the development of the nervous system and animal experiments were exclud- ed. Quality assessment was performed through bias risk evaluation in accordance with Cochrane Handbook 5.1.0 software in the Cochrane Collaboration. The homogeneous studies were analyzed and compared using Revman 5.2.6 software, and then effect model was selected and analyzed. Those papers failed to be included in the meta-analysis were subjected to descriptive analysis. MAIN OUTCOME MEASURES： Nervous system injury in preterm infants. RESULTS： Ten randomized controlled trials were screened, involving 1,038 subjects. Among them 512 cases received dexamethasone treatment while 526 cases served as placebo control group and blank control group. Meta-analysis results showed that the incidence of cerebral palsy, visual im- pairment and hearing loss in preterm infants after dexamethasone treatment within 7 days after birth was similar to that in the control group （RR = 1.47, 95%CI： 0.97-2.21; RR = 1.46, 95%CI： 0.97-2.20; RR = 0.80, 95%CI： 0.54-1.18; P 〉 0.05）, but intelligence quotient was significantly de- creased compared with the control group （MD = -3.55, 95%CI： -6.59 to -0.51; P = 0.02）.

Bronchopulmonary Dysplasia in Premature Infants with Very Low Birth Weight: A Single Centre Retrospective Study in China

引用

Open Journal of Pediatrics 2016年第4期6卷 295-307页

作者： Li Shen Tao Bo Senlin Luo ruolin zhang Jian Li Division of Neonatology Children’s Medical Center The Second Xiangya Hospital Central South University Changsha China Department of Neonatology The Maternal and Child Health Hospital of Hunan Province Changsha China

To investigate bronchopulmonary dysplasia (BPD) and its treatment with dexamethasone (DEX) in premature infants with birth weight (BW) < 1500 g. We retrospectively reviewed the records of preterm infants admitted to the Division of Neonatology, the Second Xiangya Hospital, Central South University between September 2011 and December 2014. Patients were excluded if they needed oxygen therapy but were lost to follow-up at ≤36 weeks post-menstrual age (PMA) or <56 days after birth, or they had severe congenital anomalies. The incidence of BPD was 18% (37/212). Gestational age (GA) was <32 weeks in all BPD patients. GA, BW, and Apgar scores were lower and hospitalization duration and pulmonary surfactant (PS) use were higher in the BPD group than in the non-BPD group (P < 0.05). Risk factors for BPD included neonatal respiratory distress syndrome, neonatal pneumonia, positive sputum culture, pulmonary hemorrhage, respiratory failure. Multivariate logistic regression revealed that GA (odds ratio [OR]: 0.479, P = 0.004) and neonatal respiratory distress syndrome (OR: 6.146, P = 0.043) were independent risk factors for BPD. DEX was administered to 26 patients after the diagnosis of BPD. After one and two weeks of DEX treatment, the oxygen requirement had significantly reduced compared to the week prior to treatment (P < 0.05), while during treatment, the weight gain rate and weight gain efficiency slower significantly than that during either of the two preceding weeks (P < 0.001). These results suggest that low GA was the most important risk factor for BPD, DEX reduced oxygen dependency but decreased weight gain.

Semi-Quantitative Analysis of Brain MR Imaging in 76 Cases of Neonatal Indirect Hyperbilirubinemia

引用

Open Journal of Pediatrics 2016年第4期6卷 280-289页

作者： ruolin zhang Tao Bo Li Shen Senlin Luo Jian Li Department of Pediatrics Second Xiangya Hospital Central South University Changsha China Dvision of Neonatology She Kou People’s Hospital Shenzhen China

Background: Neonatal hyperbilirubinemia is indeed common. However, severe nerve injuries and bilirubin encephalopathy are rare and only occur in the unusual cases of extreme hyperbilirubinemia. Objectives: To investigate brain magnetic resonance imaging (MRI) changes and their correlations with perinatal predisposing factors in neonates with indirect hyperbilirubinemia, via regions of interest (ROIs) analysis. Methods: Seventy-six neonates with a gestational age of ≥35 weeks diagnosed with neonatal indirect hyperbilirubinemia or bilirubin encephalopathy all underwent brain MRI during hospitalization. Depending on peak total serum bilirubin (TSB), they were assigned to group A (<221 μmol/L), B (≥221 μmol/L μmol/L), C (≥42 μmol/L μmol/L), or D (≥428 μmol/L). The globus pallidus and the white matter around the anterior horn of the lateral ventricle and posterior horn of the lateral ventricle were selected as the ROIs. Average optical densities (AODs) of the ROIs and the cerebrospinal fluid region were measured. The ratio between the AODs was designated as the relative optical density (ROD), and used to determine relative signal intensity. Results: RODs of the globus pallidus were significantly lower in group D than in all other groups. TSB and the ratio of TSB to serum albumin concentration (B/A) was significantly negatively correlated with ROD in theglobus pallidus. Corrected age was significantly negatively correlated with the ROD of the ROIs. Conclusions: Semi-quantitative image analysis is a feasible method to assess conventional brain MRI for neonatal indirect hyperbilirubinemia. The signal intensity of the globus pallidus in T1-weighted images was significantly correlated with TSB level and B/A.
