OBJECTIVE To promote the application of drones in emergency rescue and related fields， expand “low-altitude+ medical” rescue services， and advance the standardization of “low-altitude+medical” distribution services. METHODS The Consensus on Low-altitude Transport and Delivery Services for Emergency Medicines via Drones （2025 Edition） （hereinafter referred to as the Consensus） was jointly initiated by the Division of Therapeutic Drug Monitoring， Chinese Pharmacological Society and the Expert Committee on Precision Medication of the Guangdong Pharmaceutical Association. Guangzhou Red Cross Hospital served as the leading unit， organizing 53 multidisciplinary experts nationwide to participate in drafting and reviewing. A nominal group technique was employed to discuss and finalize the consensus outline， resulting in a preliminary draft. Delphi method was employed， and 11 external review experts were invited to conduct the evaluation. After the experts’ opinions were analyzed and integrated， the Consensus was finalized. RESULTS & CONCLUSIONS The finalized Consensus includes its purpose， principles， and applicable scenarios， basic requirements， and operational procedures for low-altitude transport and delivery of emergency medications； distribution requirements and precautions for controlled substances， fragile medications， and temperature-sensitive medications； and recommendations for emergency medications supplies suitable for the low-altitude transportation and distribution. The release of this Consensus is expected to provide guidance and support for the standardization of “low-altitude+medical” distribution services and the application of low-altitude economy in the healthcare sector.

Senile macular degeneration（SMD） is a degenerative disease of the macular region of the eye that causes visual impairment in older people worldwide. It is the focus and difficulty of the treatment of ophthalmic diseases at home and abroad. This paper reviewed traditional Chinese medicine （TCM） active ingredients for the treatment and prevention of SMD， and its new ocular delivery preparations. Studies have shown that many active ingredients of TCM can inhibit the progression of SMD through various ways such as anti-oxidation， solid lipid nanoparticles， microemulsions/nanoemulsions， in-situ gel， etc. However， due to the low solubility， chemical instability and difficulty in overcoming the eye barrier of most TCM active ingredients， their clinical application in the treatment of SMD is seriously hindered. New preparations， such as liposomes， solid lipid nanoparticles， microemulsion/nanoemulsion， in situ gels， have good application prospects in ocular drug delivery.

OBJECTIVE: To standardize and guide the formulation process of guideline and guarantee the evidence-based formulation of Rapid Advice Guideline for Intravenous Azithromycin in Pediatrics scientifically. METHODS: The protocol of the guideline was introduced, such as guideline-making institution and registration, establishment of project group, scope of application, declaration of interest and funding support, identification of the clinical issues and outcome indexes, evidence retrieval and processing, invastigation of patients preferences and values, economics analysis, development of recommendation, external review and approval, guideline release, dissemination and update, etc. RESULTS: The construction of guidance committee, expert group and secretarial group, the registration (registration number: IPGRP-2016CN013) of the guideline had been achieved according to this protocol; clinical issues (such as indications, usage and dosage, ADR and treatment, drug use in special population) and effectiveness, safety outcome indexes had been formed. The recommendations have been issued by the end of 2017; the full text and interpretation of the guideline will be published in 2018; the guideline will be updated in 2022. CONCLUSIONS: This protocol provides the methodological and programmatic guide and provides reference for evidence-based formulation of the guideline scientifically so as to promote clinical rational drug use.
