China Geology 2019年第1期2卷 67-84页

The South Yellow Sea Basin is a large sedimentary basin superimposed by the Mesozoic-Paleozoic marine sedimentary basin and the Mesozoic-Cenozoic terrestrial sedimentary basin, where no oil and gas fields have been discovered after exploration for 58 years. After the failure of oil and gas exploration in terrestrial basins, the exploration target of the South Yellow Sea Basin turned to the marine Mesozoic- Paleozoic strata. After more than ten years' investigation and research, a lot of achievements have been obtained. The latest exploration obtained effective seismic reflection data of deep marine facies by the application of seismic exploration technology characterized by high coverage, abundant low-frequency components and strong energy source for the deep South Yellow Sea Basin. In addition, some wells drilled the Middle-Upper Paleozoic strata, with obvious oil and gas shows discovered in some horizons. The recent petroleum geological research on the South Yellow Sea Basin shows that the structure zoning of the marine residual basin has been redetermined, the basin structure has been defined, and 3 seismic reflection marker layers are traceable and correlatable in the residual thick Middle-Paleozoic strata below the continental Meso-Cenozoic strata in the South Yellow Sea Basin. Based on these, the seismic sequence of the marine sedimentary strata was established. According to the avaliable oil and gas exploration and research, the marine Mesozoic-Paleozoic oil and gas prospects of the South Yellow Sea were predicted as follows.(1) The South Yellow Sea Basin has the same sedimentary formation and evolution history during the sedimentary period of the Middle-Paleozoic marine basin with the Sichuan Basin.(2) There are 3 regional high-quality source rocks.(3) The carbonate and clastic reservoirs are developed in the Mesozoic- Paleozoic strata.(4) The three source-reservoir-cap assemblages are relatively intact.(5) The Laoshan Uplift is a prospect area for the Lower

儿童恶性肿瘤是威胁儿童生命健康和影响儿童生命质量的重要疾病之一,为儿童第二位常见死因。随着治疗技术的不断完善与进步,肿瘤儿童的长期生存率得到显著提高,但疾病本身和治疗均可损害儿童免疫功能,导致患儿容易罹患各种感染性疾病以及继发严重并发症,甚至成为传染源,危害他人健康。疫苗接种是预防传染病最经济有效的措施。对于拥有正常免疫功能的儿童而言,疫苗接种通常利大于弊。但对这类免疫功能受损的肿瘤康复者接种疫苗的情况、接种后的效果及安全性等方面均缺乏详细数据,尚无权威且统一的接种建议。本文对国内外部分学者有关肿瘤儿童预防接种的文献和共识进行梳理和总结,旨在为我国该领域的工作与实践提供参考。

Objective： High body mass index （BMI） is considered as the most important risk factor for elevated serum alanine aminotransferase （ALT） concentration. This study examined an array of factors, including waist circumference （WC） and folate deficiency, which may mediate the association of BMI with serum ALT concentration in Chinese hypertensive adults without known hepatic diseases. Methods： A multicenter, cross-sectional study was carried out. A total of 378 patients with mild or moderate hypertension and without known hepatic diseases were recruited from five hospitals in Harbin, Shanghai, Beijing, Xi＇an, and Nanjing. Results： Of the 360 hypertensive patients with complete data in our final analysis, 13.6% had high ALT concentrations （〉40 IU/L）. Factors including BMI, WC, triglycedde level, and folate concentration were associated with ALT concentration in univariate analysis. Consistently higher preva- lence rates of elevated ALT were observed in subjects with lower folate concentrations （≥12 vs. 〈12 nmol/L, 9.9% vs. 17.8%, P=-0.03）, with higher BMI （≥28 vs. 〈28 kg/m2, 21.5% vs. 11.4%, P=-0.02） or higher WC （≥90 vs. 〈90 cm, 18.5% vs. 10.0%, P=-0.02）. However, in multivariate analysis, the association between BMI and ALT concentration disap- peared （P=-0.802 in males and 0.369 in females）, while WC in females （P〈0.001） and folate concentration （P=-0.036 in males and 0.044 in females） remained as significant predictors for ALT concentration. Conclusions： This multicenter study demonstrated that WC and low folate concentration were important factors underlying the association between BMI and ALT concentrations in Chinese hypertensive adults without known hepatic diseases.
