Abstract： Substance addiction involves multiple factors, ranging from biological, social, to cultural. But the dominant biological reductionism-based explanations focus primarily on the brain, potentially hindering a more comprehensive and inclusive research of substance addiction and its recovery. We propose that network theory, focusing on feedback loops formed by interactions between myriad psychological disorder variables, will provide a better holistic framework to understand the complexity of substance addiction. Applying network theory to substance addiction may provide new insights in (1) understanding the interrelationships and interactions between symptoms, (2) understanding the systematic integrity and dynamic changes in symptom networks, and (3) integrating multiple levels of factors into a unified theoretical framework. Also, network theory may generate new approaches for future interventions and treatments. In sum, networktheory, as a theoretical model, provide a new perspective for understanding substance addiction and its intervention. We believe this reframing will encourage more empirical research toward various other hypotheses within this framework, thus, promoting the treatment and recovery of substance addiction.

Abstract： Meta-analysis is a crucial tool for accumulating evidence in basic and applied research. In the open science era, meta-analysis becomes an important way for integrating open data from different sources. Meanwhile, because of the great researchers’ degree introduced by multiple-step and multiple-choices in each step of meta-analysis, the openness and transparency are crucial for reproducing results of meta-analysis. To (1) understand the transparency and openness of meta-analysis reports published in Chinese journals and (2) improve the transparency and openness of future meta-analysis by Chinese researchers, we developed a Chinese version of checklist for meta-analysis, which was based on the Preferred Reporting Items for Systematic Review and Meta-Analysis protocols (PRISMA) and the principle of openness and transparency, and then surveyed the methods and results of 68 meta-analysis papers in mainstream Chinese psychological journals in last five years. Our results revealed that openness and transparency of Chinese meta-analysis reports need to be improved, especially in the following aspects: the date/time and limitation of literature search, the details of screening and data collection, the flow chart of article screening, the details of effect size transformation, and the evaluation of individual research bias. The checklist we present, which lists almost all aspects that an open meta-analysis should include, can be used as a guide for future meta-analysis.

Abstract：为了揭示地下水位梯度对湿地土壤微生物群落的影响，在鄱阳湖典型碟形湖泊白沙湖洲滩湿地设置了200m×300m大样地，沿地下水位梯度划分4个样带（从湖岸到湖心依次为GT-A，GT-B，GT-C，GT-D），采集了不同梯度带的土壤样品，利用磷脂脂肪酸法分析其土壤微生物群落结构分异特征。结果表明，随着地下水位抬升，土壤pH和沙粒含量升高，而有机碳、容重、粘粒和粉粒含量降低。与地下水位最低的梯度（GT-A）相比，地下水位在地表上下波动（GT-D）时，土壤微生物量碳氮及其分配比例分别增加了2.82、4.30、5.77和7.15倍；土壤微生物总量、细菌生物量、放线菌生物量、革兰氏阳性细菌及革兰氏阴性细菌生物量分别增长了106.8%、117.2%、74.9%，107.9%和207.2%。洲滩地下水位梯度的升高增加了土壤微生物群落的环境压力，进而降低了其群落结构的多样性。土壤微生物群落结构组成与土壤pH、含水量、沙粒含量以及碳氮比呈显著相关关系，而土壤微生物商则主要受pH和土壤质地的影响。以上结果表明地下水位梯度所引起的土壤微环境变化对微生物量、土壤有机碳周转和群落结构均产生了深刻影响。

Abstract： Objective To assess the value of urinary liver-type fatty acid-binding protein (L-FABP) in early assessment of the severity of traumatic brain injury and in predicting the occurrence of acute kidney injury (AKI) following the brain injury. Methods Sixty-five patients with traumatic brain injury patients were divided into 4 groups according to their Glasgow coma scale (GCS) scores. Blood and urine samples were collected at 2, 6, 12, 24, 48 and 72 h after the injury to detect serum creatinine (SCr) level using biochemical analyzer and urinary L-FABP using enzyme-linked immunosorbent assay (ELISA), with samples from 15 healthy adults as controls. The correlations were analyzed among SCr, urinary L-FABP, GCS score upon admission and AKI occurrence. Results The patients with moderate to severe brain injuries showed significantly higher SCr and urinary L-FABP levels than the control group (P<0.05). GCS score of the patients was inversely correlated with the levels of SCr and urinary L-FABP (P<0.05), and the changes were more prominent in urinary L-FABP than in SCr. The incidence of AKI was 21.54% in these patients. In patients with AKI, urinary L-FABP reached the peak level as soon as 6 h after the injury, as compared with 24 to 48 h when peak SCr level occurred. Conclusion Urinary L-FABP can be used as a marker for early assessment of the severity of traumatic brain injury and for predicting the occurrence of AKI following the injury.
