Effective symptom management can alleviate the physical and psychological distress experienced by patients with cancer, improve quality of life, and contribute to treatment adherence and improve clinical outcomes. However, most existing guidelines are developed for healthcare professionals, and patients and the public have limited access to standardized and comprehensible guidance on symptom management. To address this gap and to facilitate effective communication and shared decision-making, this study proposes the development of a patient version of the cancer symptom management guideline. The development process will adhere to the methodological framework recommended by the Guidelines International Network and the World Health Organization. The GRADE approach will be employed to assess the certainty of evidence and to formulate recommendations. In addition, the process will be informed by the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) instrument and the Reporting Items for Practice Guidelines in Healthcare-Public or Patient Versions of Guidelines (RIGHT-PVG). This protocol outlines the establishment of the guideline working group, the identification and prioritization of key questions, evidence retrieval and appraisal, and the formulation of recommendations, with the aim of ensuring methodological rigor and transparency in the development of the patient guideline and providing methodological reference for similar guideline initiatives.

ObjectiveTo explore the impacts of material type and loading volume of rigid containers on the hydrogen peroxide low temperature plasma sterilization of thoracoscopic instruments, to identify the best rigid containers and loading volume of thoracoscopic instruments. MethodsThoracoscopic instruments sterilized by STERRAD^® 100NX hydrogen peroxide low temperature plasma in Shanghai Pulmonary Hospital affiliated to Tongji University from August to September 2024 were selected as the research items. According to the material of rigid containers, the instruments were divided into polyethylene case group (A), stainless steel case group (B) and silicone resin case group (C). In terms of the loading volume, the rigid containers were divided into (loading capacity <80%) groups of 8, 10 and 12 instruments. The results of physical monitoring, the first type of chemical indicator card monitoring, and the five types of card luminal chemical process challenge device (PCD) monitoring of the 9 groups of A8, A10, A12, B8, B10, B12, C8, C10 and C12 were compared and evaluated. ResultsCompared to A8, A10 A12, C8, C10 or C12 groups, the thoracoscope instruments in the stainless steel containers in B8, B10 or B12 group had higher hydrogen peroxide concentrations and shorter elapsed time in the pressure check phases 1 and phases 2, with the differences statistically significant (P<0.05), followed by the silicone resin case group and the polyethylene case group. The nine groups of physical parameter monitoring, the first type of chemical indicator monitoring, and the five types of chemical PCD monitoring for lumen sterilization achieved 100% qualification rates, and there were no significant differences in the qualified rates of sterilization among the 9 groups (P>0.05). ConclusionWhen using hydrogen peroxide low temperature plasma to sterilize thoracoscopic instruments, it is recommended to use stainless steel or silicone resin rigid containers with a controlled loading capacity (≤12) to ensure optimal sterilization quality.

Secondary organizing pneumonia after infection is a pathological condition characterized by connective tissue filling and obstructing the alveoli and bronchioles, in which following an infection in the lung, the inflammatory response is not controlled in a timely and effective manner. The pathogenesis and treatment of this condition can be interpreted through the Sanjiao membranous tube theory and the concept of stagnation within the pulmonary micro-membrane. Sanjiao is conceptualized as a four-way membranous tube that internally connects with the zangfu organs and externally with the skin and muscles, enabling the circulation of energy and fluids throughout the body. It also maintains communication with the zangfu micro-membranes. Within the lungs, the pulmonary micro-membrane is distributed and connected to the upper jiao membranous tube, facilitating the movement of qi and fluids and supporting nutrient distribution. External pathogens may invade the Sanjiao membranous system through the external membranous tube, travel internally along this system, and transform into latent pathogens that settle within the pulmonary micro-membrane. These latent pathogens can subsequently transform into heat or dampness, leading to the depletion of lung qi and impairing the lung′s ability to regulate and transport body fluids. Consequently, fluids may seep into the pulmonary micro-membrane, where they are transformed into dampness, turbidity, and phlegm. The accumulation of damp-turbidity and phlegm obstructs the flow of qi and blood, resulting in blood stasis in the pulmonary collaterals. This stagnation occurring within both the pulmonary micro-membrane and its associated collaterals underlies the development of secondary organizing pneumonia after infection. In severe cases, this condition may progress to pulmonary interstitial fibrosis. The therapeutic approach emphasizes expelling latent pathogens, regulating and dredging the pulmonary micro-membrane, tonifying the healthy qi, and supporting health. Regulating and dredging the pulmonary micro-membrane is a crucial step, with a focus on promoting the flow of lung qi, resolving dampness and phlegm, and activating blood circulation to remove stasis.

Autologous blood donation is an important strategy of blood conservation. The Administrative Measures for the Clinical Use of Blood in Medical Institutions (Order No. 85 of the National Health Commission) requires medical institutions to promote the implementation of autologous blood donation actively. The clinical practice guidelines for patient blood management also recommend the proactive use of autologous blood donation to reduce the reliance on allogeneic blood. Preoperative autologous blood donation (PABD) is one of the autologous blood donation with wide range of indications, easy to operate, and can effectively reduce the transfusion of allogeneic blood. However, the performance of PABD in China is unsatisfactory due to various factors such as the patient composition of medical institutions, the implementation of outpatient department of blood transfusion, the level of attention paid to this issue, and the fact that traditional PABD do not meet clinical requirements. Therefore, improving the PABD model and exploring new PABD technology, as well as promoting their clinical application, are critical measures to meet the development requirements of patient blood management and to alleviate the shortage of blood supply. This article summarizes the improvements in the PABD model, and a novel PABD technology of PABD—preoperative deep apheresis of autologous red blood cells and/or platelets (deep apheresis autologous blood storage technology), and the current situation of clinical application of PABD to provide paradigm for clinical transfusion.

Systemic sclerosis is an autoimmune rheumatic disease that often leads to multisystem diseases,frequently resulting in pulmonary interstitial fibrosis.According to the theory of sanjiao(triple energizers)membranous channels,sanjiao connects the five zang-organs and six fu-viscera internally and the skin,muscles,and bones externally.It serves as a four-way membranous channel that connects internal organs and external structures,linking with the micromembranes of organs and blood vessels.The pathogenesis of pulmonary interstitial fibrosis secondary to systemic sclerosis involves external cold obstructing the skin and interstitial layers,impairing the defense qi and defense yang,which originate in the essence of the kidney.This leads to weak defensive qi and kidney deficiency,causing stagnation in sanjiao's energy flow and disruption of water and gasification and loss of fluid,resulting in accumulation of dampness,phlegm,and blood stasis.These obstructive factors spread along sanjiao's membranous channels,leading to multiorgan micromembrane involvement and systemic damage.The lungs,which are in direct contact with the external environment,are particularly susceptible to invasion by external pathogens.When combined with stagnation of dampness,phlegm,and blood in the lungs,this leads to secondary pulmonary fibrosis,resulting in lung dysfunction.Continuous stagnation of sanjiao exacerbates the overall condition of the patient,leading to a mixed cold-heat imbalance.Treatment focuses on"unblocking,transforming,and regulating"to restore sanjiao function,promote qi and fluid circulation,invigorate blood,and adjust the cold-heat imbalance,ultimately restoring the overall condition of the patient.
