Participatory flood risk mapping(PFRM) is a well-recognized and widely implemented tool for meaningful community involvement in disaster risk reduction(DRR). The effectiveness of PFRM remains anecdotal. The PFRM exercise has rarely been applied identically in two different places by two different organizations, which produces varied and uncertain outcomes. In the absence of any agreed and comprehensive framework for participatory DRR, existing studies struggle to provide a scientific account of how the structure, design, and process of PFRM ensure the effective participation of local *** study, examines what factors and methods make PFRM an effective participatory DRR tool. In this study,we first identified the process-based criteria of participation. Then we briefly introduced a participatory flood risk mapping exercise conducted in a flood-prone informal settlement in Dharavi, Mumbai. The exercise was carefully designed to meet the process criteria of effective participation. Finally, using qualitative research methods, we evaluated the effectiveness of our PFRM from the local community perspective. The findings show that ensuring community livelihood security and true involvement of marginalized groups, preparing an action plan, and incorporating fun and cultural connotations into the facilitation process are critical components that enhance community participation through PFRM in DRR.

目的研究术后通气方对术后肠麻痹(POI)小鼠肠道损伤的改善作用及机制。方法将小鼠随机分为假手术组、模型组、阳性对照组(枸橼酸莫沙必利片,1.95 mg/kg)、术后通气方组(1.88 g/kg),每组6只。除假手术组外,其余各组小鼠使用经典小肠干扰术制备POI模型。各组小鼠灌胃相应药液/水,每天1次,连续2 d。末次给药后,检测小鼠肠道炭末推进率;观察小鼠回肠组织病理形态学变化;检测小鼠血清中白细胞介素6(IL-6)、IL-10、肿瘤坏死因子α(TNF-α)、胃动素(MTL)和生长抑素(SS)水平;检测小鼠回肠组织中Toll样受体4(TLR4)、核因子κB p65(NF-κB p65)、p38丝裂原活化蛋白激酶(p38 MAPK)表达水平;分析小鼠结肠内容物的肠道菌群结构。结果经术后通气方干预后,小鼠回肠组织肠壁萎缩、黏膜毛细血管充血等病理损伤明显改善;小肠炭末推进率和血清中IL-10、MTL水平均显著升高(Phao1、Shannon、PD指数以及阿克曼氏菌属(Akkermansia)相对丰度(P<0.05),显著降低变形菌门(Proteobacteria)、酸鱼联合乳杆菌属(Ligilactobacillus)、大肠埃希菌属-志贺氏菌属(Escherichia-Shigella)相对丰度(P<0.05)。结论术后通气方可改善POI小鼠肠道损伤及炎症反应,其作用机制可能与抑制TLR4/NF-κB/MAPK信号通路活性,调节胃肠激素水平,改善肠道菌群紊乱有关。

Background: Electroacupuncture(EA) may reduce the severity of acute pancreatitis(AP) and provide additional pain relief in patients with chronic pancreatitis. However, the ability of EA to relieve pain in patients with AP has not been well ***: This study was undertaken to compare the pain-relieving effects of EA and conventional treatment in patients with ***, setting, participants and interventions: This study was conducted using a randomized, controlled,three-arm, parallel-group and multi-center design. Patients diagnosed with AP were randomly and equally assigned to EA1, EA2 or control groups. All participants received conventional standard-of-care therapy for AP. Local EA alone was administered in EA1, and local plus distal EA was given in *** EA included two abdominal acupoints, while distal EA included twelve peripheral acupoints. EA groups underwent one session of EA daily for 4 days(days 1–4), or until pain was resolved or *** outcome measures: The primary outcome measure was the change in the visual analogue scale(VAS;0–100) pain score between baseline and day ***: Eighty-nine participants were randomized into EA1, EA2 and control groups, and 88(EA1, 30;EA2, 29;control, 29) were included in the full-analysis set. VAS score change(median [interquartile range]) on day 5 was(12.3 ± 22.5) in the EA1 group,(10.3 ± 21.5) in the EA2 group, and(8.9 ± 15.2) in the control group. There were not significant differences in the change in VAS score among treatments(P = 0.983). However, time to food intake was significantly shorter in the EA group(EA1 + EA2) than in the control group(median 2.0 days vs 3.0 days), with a hazard ratio of 0.581(P = 0.022;95% CI,0.366–0.924). No significant adverse events ***: EA treatment did not significantly reduce pain after 4 days of treatment in patients with AP-associated abdominal pain but significantly reduced time to first food intake.

目的探讨血清维生素D水平与儿童支气管哮喘预后的相关性。方法收集2021年1月—2022年12月来银川市妇幼保健院儿科门诊就诊的4~12岁儿童作为研究对象,包括支气管哮喘患儿162例和同一年龄段健康儿童167名(对照组)。检测内容包括血清维生素D浓度和血清总IgE浓度。通过统计学方法确定血清维生素D水平与儿童支气管哮喘预后的相关性。结果患有支气管哮喘的儿童血清维生素D3的水平低于对照组,但两组的总体维生素D水平偏低(中位数分别是9.4 ng/ml和12.6 ng/ml)。在儿童哮喘患儿中,在低维生素D组,观察到高IgE阳性率。结论儿童支气管哮喘患儿血清维生素D3水平较低,但具体生物学机制尚不清楚。

流行性感冒病毒(简称流感病毒)每年引起较高的人群发病率和死亡率,对全球公共卫生安全构成严重威胁。流感病毒经过不断进化,具有躲避宿主免疫反应和逃避疫苗保护的能力。因此,有必要开发针对宿主细胞机制的药物或疫苗以降低重症率和死亡率。自然杀伤细胞(NK细胞)能够在非致敏状态下迅速杀伤病毒感染的宿主细胞,并具有免疫调节及记忆效应,为流感病毒的防治带来了希望。该文就NK细胞及其免疫激活在流感中的作用机制进行综述,为流感防治的新型药物或疫苗研究提供依据。

针对静态机器学习模型难以有效反映滑坡的动态演化特性,且存在时序过长时历史数据遗忘导致位移预测结果不稳定的问题。提出一种基于鲸鱼优化卷积神经网络(convolutional neural networks, CNN)和双向门控循环神经网络(bidirectional gated recurrent neural network, BiGRU)的滑坡位移动态预测方法。首先对滑坡影响因子进行特征筛选,构建数据集,建立CNN-BiGRU网络模型,使用鲸鱼优化算法(whale optimization algorithm, WOA)对模型进行超参数寻优,使用CNN网络模型从滑坡数据中提取潜在的特征向量,将特征向量以时间序列的形式输入BiGRU模型中,利用其处理时间序列数据的优势,完成滑坡位移预测。结果表明:所提出模型得到的滑坡位移预测精度较高,与未优化的CNN-BiGRU相比均方根误差(root mean square error, RMSE)下降了0.030 5 mm。
