Coastal zones, with their significant geodiversity, are vital areas for geotourism. Effective management is crucial to harness the geological interest of these sites as geotourism resources while ensuring their conservation. ManabíProvince is one of the most representative regions along the Ecuadorian coast due to its beaches and coastal cliffs, offering a wealth of tourist attractions and cultural elements. This study aims to evaluate the geosite potential of six cliffs in ManabíProvince through quantitative and qualitative analyses to propose geotourism promotion strategies. The methodology involves (i) inventory and characterisation of the cliffs, (ii) assessment of the sites by the Spanish Inventory of Places of Geological Interest method (IELIG), and (iii) qualitative evaluation through focus group discussions and Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis. The results reveal that all six sites boast diverse geological assets, including geomorphological, stratigraphic, sedimentological, and tectonic elements. They are characterised by “high ”scientific, didactic, and tourist interest, while also being sus- ceptible to degradation due to natural and anthropic threats. The SWOT analysis demonstrates that the valuable geological and geomorphological heritage of potential geosites provides an opportunity to foster geotourism and boost the province’s economy, incorporating geoconservation and geoeducation strategies. This study proposes a georoute called “Ruta Acantilados del Sol ”, a 245 km journey encompassing all six sites, incorporating diverse tourist and cultural activities. Our research lays the foundation for fostering geotourism along the Manabícoast and strengthening the connection between nature, heritage, and the welfare of residents within a global resilience plan.

For histochemistry, infected tissue sections with attached cysts were processed for haematoxylene and eosin staining. Cysts were aseptically fed to 4 day old leghorn chicken to obtain adult worms. Mechanically excysted metacercaria and the ovigerous adult worms were stained in carmine to prepare permanent ***:One year survey for the infection of encysted progenetic metacercaria of ***. punctatusrevealed the prevalence, intensity and abundance of 24.7%, 2.27and 0.608, respectively. Histopathology showed heavy infiltration of immune cells at the site of cyst attachment and some tissue damage was also evident. Following feeding to experimental chicken, about 41.07% of the encysted metacercariae were able to excyst and migrate back to bucco-pharyngeal region where they tenaciously attached and fed on blood, and transformed into ovigerous adult worms from 62 hours onwards of post ***:The parasite is potentially pathogenic to the host, and the availability of a suitable intermediate host can be a contributing factor for the occurrence of C. complanatummetacercaria either in the excysted or encysted form, indicating loose host specificity and zoonotic potential.

目的探索维持性血液透析患者不同症状群间的关联关系,识别连接不同症状群的桥梁症状。方法采用便利抽样法,使用透析症状指数量表对480例维持性血液透析患者进行问卷调查。基于网络分析识别症状群间的桥梁症状。结果维持性血液透析患者经历着6个症状群,分别为皮肤症状群、尿毒症症状群、胃肠道症状群、情绪症状群、水电解质症状群与性功能障碍症状群。桥梁中心性指标显示桥梁强度最大的症状是担心(r_(bs)=7.946)和皮肤干燥(r_(bs)=7.800);桥梁紧密中心性最大的症状是担心(r_(bc)=0.331)和伤心(r_(bc)=0.322);桥梁中介中心性最大的症状是性欲减退(r_(bb)=12.000)和入睡困难(r_(bb)=7.000)。结论维持性血液透析患者受多个症状群困扰,担心和皮肤干燥是连接不同症状群的桥梁症状。针对桥梁症状进行精准干预,有利于阻断其在不同症状群间的桥接作用,提高症状管理效能。

作者： HU Xi-hong pa Mi-er SHEN Quan-li HUANG Guo-ying Department of Radiology Children's Hospital of Fudan University Shanghai 201102 China Heart Centre Children's Hospital of Fudan University Shanghai 201102 China

The left pulmonary artery sling （LpaS） is a rare vascular anomaly causing respiratory distress in which theleft pulmonary artery arises from the posterior aspect of the right pulmonary artery, courses posteriorly to the right of the bronchus and passes between the trachea and oesophagus to reach the hilum of the left lung. The LpaS is frequently associated with tracheobronchial tree anomalies and congenital cardiac defects. Proper assessment of the tracheobronchial and cardiovascular anomaly is essential in LpaS for planning management of the patient. Currently,
