Toward managing mixed-species stands： from parametrization to prescription

A better understanding and a more quantitative design of mixed-species stands will contribute to more integrative and goal-oriented research in mixed-species forests. Much recent work has indicated that the structure and growth of mixed species forests may fundamentally differ from monocultures. Here we suggest how to progress from the present accumulation of phenomenological findings to a design of mixed-species stands and advanced silvicultural prescriptions by means of modelling. First, the knowledge of mixing effects on the structure and growth at the stand, species, and individual tree level is reviewed, with a focus on those findings that are most essential for suitable modelling and silvicultural designs and the regulation of mixed stands as opposed to monocultures. Then, the key role of growth models, stand simulators, and scenario assessments for designing mixed species stands is discussed The next section illustrates that existing forest stand growth models require some fundamental modifications to become suitable for both monocultures and mixed-species stands. We then explore how silvicultural prescriptions derived from scenario runs would need to be both quantified and simplified for transfer to forest management and demonstrated in training plots. Finally, we address the main remaining knowledge gaps that could be remedied through empirical research.

Analysis of the prescription of auricular acupoint therapy for simple obesity based on complex network techniques

Objective： To explore the core acupoints and combination rules of auricular acupoint therapy for simple obesity, and to further analyze the characteristics of the prescription of auricular acupoint therapy for simple obesity.Methods： Relevant clinical study literature in recent 30 years in PubMed, China Biology Medicine disc（CBM）, China National Knowledge Infrastructure（CNKI）, Wan Fang Database. VIP Database and TCM Online Database was retrieved, and eligible articles were selected in order to build a prescription database of auricular acupoint therapy for simple obesity. On the basis of complex network techniques, the core acupoints and combination rules of auricular acupoint therapy for simple obesity were analyzed, and the characteristics of auricular acupoint therapy for simple obesity were analyzed comprehensively.Results： There were 46 network nodes of auricular acupoint. The top 16 core acupoints for auricular acupoint therapy for simple obesity included Nèifēnmì（内分泌CO18）, Pí（脾CO13）, Wèi（胃CO4）, Sānjiāo（三焦CO17）, Jīdiǎn（饥点）.Shénmén（神门TF4）. Dàcháng（大肠CO7）. Pízhìxià（皮质下AT4）. Fèi（肺CO14）. Shèn（肾CO10）. Jiāogǎn（交感AH6 a）, Kǒu（口CO1）,Gān（肝CO12）. Xiǎocháng（小肠CO6） and Nǎo（脑）. The combination of auricular acupoints was mainly based on the main indications of acupoints. The analysis of auricular acupoints combination indicated that the combination of CO4 with CO18 was applied most frequently, which was followed by the combinations of CO13 with CO18 and CO13 with C04. According to the analysis of auricular acupoint stimulation methods, ear point taping and pressing with Wángbùliúxíng（王不留行,Semen Vaccariae） seeds was used frequently, which was followed by magnetic beads taping and pressing and pyonex therapy. Auricular acupoint therapy combined with acupuncture for simple obesity was used most commonly, which was followed by auricular acupoint therapy combined with catgut embedment in acupoint and simple auricular acupoint therapy.Conclusion： In this study, the core acupoints and combinations of auricular acupoint therapy for simple obesity were explored effectively, and the pressing materials and major combined intervention methods were summarized and analyzed, thus providing references and treatment thoughts in terms of the point and prescription selection of auricular acupoint therapy for simple obesity.
