川东北地区社会心理服务现状调查

目的 调查川东北地区各组织机构开展社会心理服务的现状以及居民的心理健康状况，为该地区社会心理服务体系建设工作的进一步开展提供参考。方法 采用自编调查表对巴中市通江县、广元市利州区、达州市大竹县共计148家组织机构进行调查，包括各组织机构社会心理服务体系建设工作现状及心理健康服务开展情况；采用患者健康问卷抑郁量表（PHQ-9）、广泛性焦虑障碍量表（GAD-7）和自编心理健康服务需求调查表，对三地试点地区21 505名居民的心理健康状况及其对心理服务的需求进行调查。结果 在试点地区148家组织机构中，81家（54.7%）机构有开展心理健康服务的场所，58家（39.2%）机构配备了专兼职心理健康服务工作人员。在2019年，有95家（64.2%）机构开展了职工心理健康服务活动，104家（70.3%）机构开展了心理健康科普宣传活动。在75家教育机构中，67家（89.3%）机构对学生开展了心理健康教育活动，47家（62.7%）机构实现了心理健康课程在学生中全覆盖。居民的抑郁、焦虑检出率分别为36.8%和30.8%，有83.7%的居民有心理健康服务的需求，主要集中在个人成长、婚姻家庭、子女教育和压力管理方面。结论 川东北三市试点地区的社会心理服务工作有序进行，场地、经费及人才保障有待进一步加强。居民的抑郁和焦虑问题较突出，且对心理健康服务的需求较高。     

蕲蛇的鉴别研究进展＊

蕲蛇是《中国药典》收载的三种蛇类药材（含蕲蛇、乌梢蛇、金钱白花蛇）之一，具有祛风、通络、定惊止痉等功效，其药用价值和经济价值较高，市场需求量较大，为贵细药材。近年来，由于野生资源逐渐匮乏，在经济利益驱使下，蕲蛇商品普遍存在着伪品、混淆品、掺假品，这种质量不一、以次充好、以假代真的情况容易导致用药安全问题。本文通过总结蕲蛇的性状鉴别、显微鉴别、理化鉴别和分子鉴别，以期为蕲蛇等蛇类药材的真伪鉴别和质量的优劣检测提供思路，为进一步鉴别研究、制剂开发提供参考依据，确保用药质量。     

经动脉栓塞术治疗食管癌出血14例

【摘要】 目的 探讨经动脉栓塞术（transarterial embolization，TAE）治疗食管癌出血的有效性及安全性。方法 收集2018年1月至2020年12月行TAE治疗的14例食管癌出血患者的临床资料、技术成功率、临床成功率，严重并发症情况。评估TAE治疗的有效性及安全性。结果 14例患者中导管成功选择性插入靶动脉并行栓塞患者11例。9例患者接受治疗后未再出现出血征象。出血的主要责任血管为胃左动脉7例，支气管动脉6例和食管固有动脉6例。栓塞材料为微弹簧圈、明胶海绵颗粒及聚乙烯醇颗粒。常见不良反应有疼痛、发热，其中1例患者发生食管瘘。结论 对于内科治疗无效的食管癌出血，TAE可以起到良好的疗效。食管瘘作为术后的严重并发症，需特别注意预防。对于胸段食管癌及食管胃交界处癌，最常见的责任血管为胃左动脉、支气管动脉及食管固有动脉。     

黄芩素调控 NLRP3 / Caspase-1 通路对牙周炎大鼠牙槽骨吸收的影响

目的 探索黄芩素调控核苷酸结合寡聚化结构域样受体蛋白 3 ( nucleotide-binding oligomerization domain-like receptor protein 3, NLRP3) / 半胱氨酸天冬氨酸蛋白酶 1 ( cysteine aspartate protease 1, Caspase1) 通路对牙周炎大鼠牙槽骨吸收的影响。 方法 将 40 只牙周炎大鼠随机分为模型组、 黄芩素组、 激活剂 组、 黄芩素 + 激活剂组, 另取 10 只正常作为对照组。 检测大鼠釉牙骨质界到牙槽嵴顶 (CEJ-AC) 的距离、 血清中白细胞介素-6 (IL-6)、 转化生长因子-β (TGF-β) 含量以及牙周组织病理变化、 IL-6、 TGF-β 阳性 表达和 NLRP3、 Caspase-1 蛋白表达。 结果 模型组大鼠 CEJ-AC、 NLRP3、 Caspase-1、 IL-6、 TGF-β 水平及 阳性表达水平以及蛋白表达水平均升高 (P< 0. 05); 经黄芩素干预后, 各项指标均降低 (P< 0. 05); 引入 激活剂明显削弱了黄芩素对牙周炎大鼠的抗炎作用。 结论 黄芩素通过抑制 NLRP3 / Caspase-1 通路减轻炎性反应, 控制牙槽骨吸收。     

Global colorectal cancer research, 2007-2021: Outputs and funding

The purpose of this study was to provide an evidence base for colorectal cancer research activity that might influence policy, mainly at the national level. Improvements in healthcare delivery have lengthened life expectancy, but within a situation of increased cancer incidence. The disease burden of CRC has risen significantly, particularly in Africa, Asia and Latin America. Research is key to its control and reduction, but few studies have delineated the volume and funding of global research on CRC. We identified research papers in the Web of Science (WoS) from 2007 to 2021, and determined the contributions of the leading countries, the research domains studied, and their sources of funding. We identified 62 716 papers, representing 5.7% of all cancer papers. This percentage was somewhat disproportionate to the disease burden (7.7% in 2015), especially in Eastern Europe. International collaboration increased over the time period in almost all countries except in China. Genetics, surgery and prognosis were the leading research domains. However, research on palliative care and quality-of-life in CRC was lacking. In Western Europe, the main funding source was the charity sector, particularly in the UK, but in most other countries government played the leading role, especially in China and the USA. There was little support from industry. Several Asian countries provided minimal contestable funding, which may have reduced the impact of their CRC research. Certain countries must perform more CRC research overall, especially in domains such as screening, palliative care and quality-of-life. The private-non-profit sector should be an alternative source of support.     

What Should We Focus on in Sepsis Fluid Resuscitation?--A Research Based on Scientometrics and Visual Analysis

Sepsis is a life-threatening condition and a global disease burden.Heterogeneous syndrome is defined as severe organ dysfunction caused by a dysregulated host response to infection,with renewed emphasis on the immune pathophysiology.Researchers worldwide constantly update the diagnostic criteria of sepsis and have introduced concepts such as“sepsis-3”“Surviving Sepsis Campaign(SSC)”“Early Goal-Directed Therapy(EGDT)”,the 3-h and 6-h bundles to an hour-1 bundle[1],“limited ventilation”“the best PEEP[2]”,and“Lung Protective-Ventilation”.Despite all efforts of experimental and clinical research during the last three decades,the ability to positively influence the course and outcome of the syndrome remains limited.
