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.

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.

Objective To investigate the relationship between the expression levels of mir-155/Th17 and mir-23b-3p/Tfh in peripheral blood and the prognostic value of secondary atopic dermatitis(AD)in AIDS patients.Methods In this study,80 AIDS patients were treated in our hospital from February 2021 to December 2023.The subjects were divided into AD group and non-AD group according to whether they had secondary AD.The levels of mir-155,Th17,mir-23b-3p and Tfh in peripheral blood of AD group and non-AD group were compared.Spearman method was used to analyze the relationship between levels of mir-155,Th17,mir-23b-3p and Tfh in peripheral blood and secondary AD in AIDS patients.At the same time,according to the prognosis of patients,the subjects were divided into good prognosis group and poor prognosis group,and the risk factors affecting the prognosis of patients were screened by Logistic regression analysis.Receiver operating characteristic(ROC)curve was drawn to analyze the predictive value of peripheral blood mir-155,Th17,mir-23b-3p and Tfh levels on the prognosis of AIDS patients.Results Compared with non-AD group,the levels of miR-155,Th17 and Tfh in peripheral blood of AD group were higher(P＜0.05),and the levels of miR-23b-3p were lower(P＜0.05).The level of miR-155,Th17 and Tfh in peripheral blood were positively correlated with secondary AD of AIDS(r=0.487,0.492,0.495,P＜0.05),and the level of miR-23b-3p in peripheral blood was negatively correlated with secondary AD of AIDS(r=-0.503,P＜0.05).The levels of HIV load(high dose),lymphoma,PLT,NLR,CRP,miR-155,Th17 and Tfh in the poor prognosis group were higher than those in the good prognosis group(P＜0.05),while the levels of albumin and miR-23b-3p in the poor prognosis group were lower than those in the good prognosis group(P＜0.05).Logistic regression analysis showed that lymphoma,PLT,NLR,low albumin,CRP,miR-155,Th17,Tfh and low miR-23b-3p were all risk factors for poor prognosis of AIDS patients(P＜0.05).ROC curve results showed that the AUC(95％CI)and sensitivity of combined detection of peripheral blood miR-155,Th17,Tfh and miR-23b-3p in predicting poor prognosis of AIDS patients were 0.883(0.805～0.992)and 96.70％,respectively.All of them were higher than the above peripheral blood indexes alone(P＜0.05).Conclusion The abnormal expression of miR-155,Th17,Tfh,and miR-23b-3p in peripheral blood is closely related to secondary AD in AIDS patients,and is a risk factor affecting the poor prognosis of AIDS patients.The combined detection of these indicators has a high predictive value for the poor prognosis of AIDS patients.

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.

With acute myocardial infarction as the target outcome, 8 influencing factors selected by LASSO regression, and 5 independent influencing factors were found after multiple Logistic regression, those were age ( OR=1.21, 95% CI: 1.12-1.31; P<0.001), pre-infection ( OR=0.02, 95% CI: 0.01-0.06; P<0.001), body temperature ( OR=0.37, 95% CI: 0.18-0.77; P=0.008), chest pain ( OR=26.75, 95% CI: 5.87-121.81; P<0.001) and white blood cell count ( OR=1.27, 95% CI: 1.12-1.44; P<0.001). Younger age, high body temperature and pre-infection are independent predictors for acute myocarditis, while chest pain and elevated white blood cell count are independent predictors for acute myocardial infarction. The five influencing factors selected by multivariate logistic regression and their combined diagnostic model were subjected to ROC analysis. The AUC reached 0.969, sensitivity reached 0.940 and specificity reached 0.925. Calibration curve and decision curve analysis(DCA) demonstrate that the model possesses excellent clinical application value. In conclusion, age, chest pain, pre-infection, body temperature and white blood cell count were independent factors in distinguishing acute myocardial infarction and acute myocarditis in young people. The clinical differential diagnosis model based on 5 independent factors may has high efficiency and good clinical practicability.

Objective To screen out the predictive factors for prognosis of migraine patients with patent foramen ovale(PFO)after occlusion,and to observe the value of predictive model based on these factors.Methods A total of 102 migraine patients with PFO who underwent occlusion of PFO were retrospectively included.Based on right to left shunt(RLS)grade in contrast-enhanced transcranial Doppler(TCD)and changes of migraine disability assessment(MIDAS)grade after occlusion,the patients were divided into effective group(n=56)and ineffective group(n=46).Patients'basic data and imaging data including contrast-enhanced TCD and transesophageal echocardiography(TEE)before occlusion were compared between groups.Independent predictive factors were screened using multivariate logistic regression,then a predictive model was established,and its performance was evaluated.Results Compared with ineffective group,effective group had a lower proportion of female patients,a higher proportion of patients with aura symptoms,also higher MIDAS scores before occlusion,lower left to right shunt(LRS)velocities through the defect,and higher RLS grades in contrast-enhanced TCD and TEE right heart contrast echocardiography before occlusion(all P＜0.05).Patients'gender,LRS velocity through the defect and RLS grade in TEE right heart contrast echocardiography before occlusion were all predictive factors for prognosis of migraine patients with PFO after occlusion of PFO(all P＜0.05).The established model demonstrated good discrimination,calibration and clinical net benefit.Conclusion Patients'gender,LRS velocity through the defect and RLS grade in TEE right heart contrast echocardiography before occlusion were all significant predictors of prognosis of migraine patients with PFO after occlusion,and the predictive model established based on these factors demonstrated certain clinical value.

Objective To explore the value of artificial intelligence-assisted compressed sensing(ACS)-MR cine imaging(Cine)for assessing biventricular function and left ventricular myocardial strain compared with conventional cardiac Cine and united compressed sensing(uCS)-Cine.Methods A total of 30 subjects who underwent conventional Cine,uCS-Cine and ACS-Cine were prospectively enrolled.Based on a 5-point scale,subjective scoring of image quality was performed and compared among 3 sequences.Biventricular function parameters and myocardial strain parameters of the left ventricle,including left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV),left ventricular ejection fraction(LVEF),left ventricular end-diastolic mass(LVEDM),right ventricular end-diastolic volume(RVEDV),right ventricular end-systolic volume(RVESV),right ventricular ejection fraction(RVEF),left ventricular global radial strain(LVGRS),left ventricular global circumferential strain(LVGCS)and left ventricular global longitudinal strain(LVGLS)were measured and compared among sequences.Results The subjective image quality scores of all 3 sequences were≥3,of ACS-Cine and conventional Cine were not significantly different(adjusted P=0.306)but both slightly higher than that of uCS-Cine(both adjusted P＜0.05).LVEDV,LVEF and LVEDM based on ACS-Cine and uCS-Cine were not significantly different(all adjusted P＞0.05),but all lower than those of conventional Cine(all adjusted P＜0.05).No significant difference of LVESV was found between each two sequences(all adjusted P＞0.05).RVEDV based on ACS-Cine was lower than that based on conventional Cine,RVESV based on ACS-Cine was higher than that based on uCS-Cine,and RVEF based on ACS-Cine was lower than that based on uCS-Cine and conventional Cine(all adjusted P＜0.05),while no significant difference of right ventricular functional parameters was observed between uCS-Cine and conventional Cine(all adjusted P＞0.05).Both ACS-Cine and uCS-Cine had lower LVGRS and LVGCS than conventional Cine(all adjusted P＜0.05),with no significant difference was found between uCS-Cine and ACS-Cine(both adjusted P＞0.05).No significant difference of LVGLS was observed among 3 sequences(P＞0.05).Conclusion ACS-Cine could be used as appropriate supplement to conventional Cine for clinical assessment of biventricular function and left ventricular myocardial strain.
