文摘BACKGROUND The unique survival environment of Helicobacter pylori(H.pylori)presents challenges in establishing appropriate in vitro culture conditions.The fastidious nature of H.pylori and its relatively low growth rate emphasize the need for customized culture conditions,which are essential for both research and clinical applications.AIM To identify the optimal liquid culture medium for H.pylori using both reference and clinical strains.METHODS Nine H.pylori strains were incubated in 10 different broth media commonly used for bacterial cultures under microaerophilic conditions.Bacterial concentrations were estimated using serial dilutions and the pour plate method.A range of H.pylori initial inoculum concentrations was tested for each strain.For growth evaluation,optical density at 600 nm was measured at 24,48,and 72 hours.The growth trends of H.pylori were compared among strains and media.RESULTS All H.pylori strains grew successfully over time,regardless of the initial inoculum concentration.The specific growth trends and the broth that yielded the highest optical density value at each time point varied with strain.The reference strains(H.pylori 26695,ATCC 43504,and J99)consistently exhibited robust growth,whereas the clinical strains displayed distinct media preferences.Overall,bacterial growth was higher in chopped meat carbohydrate broth,Columbia broth,and fastidious anaerobe broth than in Brucella broth after 72 hours.CONCLUSION Chopped meat carbohydrate broth was the most effective for H.pylori liquid culture,and Columbia broth and fastidious anaerobe broth also supported greater growth than Brucella broth.
文摘Cultural artifacts exhibitions are among the most profound and appealing forms of cultural exchange.These exhibitions serve as an important bridge for fostering friendly relations between countries and bringing people closer together.

文摘Chengdu teahouses,as core public spaces in marketplace society,have undergone transformative reconstruction-from“containers of everyday life”to“containers of commercial traffic and digital flows”-during the process of modernization.Employing spatial archaeology as a methodology,combined with fieldwork and analysis of historical documents,this study systematically examines the diachronic evolution of architectural forms,functional orientations,and social networks within Chengdu teahouses.The study reveals the logic of spatial reconstruction under the interplay of multiple forces,including cultural heritage preservation,capital-driven development,and technological intervention.The findings identify three paradigms of spatial transformation in teahouses.First,heritage specimenization,which reinforces the continuity of collective memory through symbolic extraction but risks diminishing the vitality of everyday social interactions.Second,consumption upgrading,which caters to the demands of emerging groups through iterative business models yet necessitates vigilance against spatial differentiation eroding marketplace inclusivity.Third,digital parasitism,which expands communicative dimensions through technological empowerment but confronts the risk of flattening localized knowledge.These paradigms reflect both adaptive responses of traditional spaces to contemporary pressure and the tension of reconstruction imposed by instrumental rationality on marketplace networks.The study demonstrates that spatial transformation in Chengdu teahouses is not unidirectional alienation but rather a multifaceted configuration where the continuity of tradition coexists with innovative practices amid functional diversification.This research advocates for striking a balance between the preservation of traditional spaces and modern renewal and explores organic integration approaches for traditional and modern elements,thereby providing a theoretical framework and practical insights for the transformation of traditional public spaces.
