Based on spleen deficiency-phlegm dampness as the core pathogenesis of obesity， and integrating recent advances in modern medicine regarding the key role of immune inflammation in obesity， this paper proposes a multidimensional pathogenic network of "obesity-spleen deficiency-phlegm dampness-immune imbalance". Various traditional Chinese medicine （TCM） herbs that strengthen the spleen， regulate qi， and resolve phlegm and dampness can treat obesity by improving spleen-stomach transport and transformation， promoting water-damp metabolism， and regulating immune homeostasis. This highlights immune inflammation as an important entry point to elucidate the TCM concepts of "spleen deficiency-phlegm dampness" and the therapeutic principle of "strengthening the spleen and eliminating dampness to treat obesity". By systematically analyzing the intrinsic connection between "spleen deficiency generating dampness， internal accumulation of phlegm dampness" and immune dysregulation in obesity， this paper aims to provide theoretical support for TCM treatment of obesity based on dampness.

ObjectiveTo investigate the preventive effect and mechanism of Dendrobium officinale （DO） on non-alcoholic fatty liver disease （NAFLD） by network pharmacology and animal experiments. MethodsDO components in blood after administration were identified and analyzed using ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high-resolution mass spectrometry （UPLC-QE-HF-MS/MS）. Network pharmacology and molecular docking methods were employed to obtain active ingredients and potential targets of DO for NAFLD control. High-fat feeds were used to replicate the NAFLD rat model. Biochemical kits were used for detecting the expression levels of blood lipids， hepatic lipids， and liver functions of rats. Hematoxylin-eosin （HE） staining and oil red O staining were employed to observe pathological changes in rat liver， and real-time fluorescence quantitative PCR （Real-time PCR） assay was performed to validate potential targets obtained from the network pharmacology analysis. ResultsA total of 13 DO components were identified in blood， including berberine， dihydrosanguinarine， and oxypeucedanin. A total of 14 potential targets were screened through network pharmacology， including Forkhead box protein O1 （FoxO1）， epidermal growth factor receptor （EGFR）， and insulin-like growth factor 1 （IGF-1R）， involving pathways such as the advanced glycation end product （AGE）/receptor for AGE （RAGE） signaling pathway， blood lipids and atherosclerosis， insulin resistance， and FoxO signaling. The results of animal experiments showed that the NAFLD rat model was successfully replicated. After the preventive treatment with DO for NAFLD rats， the indexes of blood lipids， hepatic lipids， and liver function were normalized； lipid deposition and lesions in the liver were significantly improved； the expression level of FoxO1 mRNA in the liver was significantly reduced （P<0.05）， and the mRNA expression levels of phosphatidylinositide 3-kinases （PI3K）， protein kinase B （Akt）， EGFR， and IGF-1R were significantly increased （P<0.05）. ConclusionDO has a preventive effect on NAFLD rats， and the mechanism of action may be related to the modulation of IGF1R and EGFR targets and activation of the PI3K/Akt/FoxO1 signaling pathway.

Objective:To evaluate the efficacy of transnasal high-flow humidified oxygen therapy in preventing hypoxemia in pediatric patients undergoing gastroscopy.Methods:In this prospective randomized controlled study, 226 pediatric patients, aged 6-12 yr, with a body mass index of 18-25 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing painless gastroscopy at Women and Children′s Hospital of Qingdao University from February 2022 to August 2023, were selected and divided into 2 groups ( n=113 each) using the simple randomization method: normal nasal cannula oxygen therapy group (group N) and transnasal high-flow humidified oxygen therapy group (group H). Anesthesia was induced with intravenous nalbuphine hydrochloride 0.1 mg/kg and propofol 2 mg/kg, and gastroscopy was performed when the Modified Observer′s Assessment of Alertness/Sedation score reached 1. During the operation, group N inhaled oxygen 5 L/min through the nasal catheter; group H inhaled a mixture of air and oxygen through a transnasal high-flow humidified oxygen therapy system at 2 L·kg -1·min -1 (not exceeding 40 L/min), with FiO 2 of 40%. Primary outcomes were the occurrence of hypoxemia and the lowest SpO 2. Secondary outcomes included the requirement for airway interventions (jaw thrust, mask ventilation, endotracheal intubation) and incidence of adverse events (nasal dryness, laryngospasm, apnea, upper airway obstruction, abdominal distension, nausea and vomiting) and endoscopist′s satisfaction with the procedure. Results:A total of 214 patients finally completed the trial, with 106 in group N and 108 in group H. Compared with group N, the incidence of hypoxemia was significantly decreased (17.9% [19/106] versus 2.8% [3/108]), the lowest SpO 2 was increased, the requirement for jaw lifting interventions was reduced, the incidence of nasal dryness was decreased, and the degree of endoscopist′s satisfaction with the procedure was increased ( P<0.05), and no significant change was found in the other outcomes in group H ( P>0.05). Conclusions:Transnasal high-flow humidified oxygen therapy can effectively prevent hypoxemia and raise the safety of pediatric patients during the gastroscopy.

Objective:To evaluate the dosimetric characteristics of intensity-modulated proton therapy (IMPT) and photon volumetric modulated arc therapy (VMAT) in radiation therapy planning for patients with bilateral breast cancer after breast-conserving surgery.Methods:On the computed tomography localization images of 18 patients with bilateral breast cancer, target volumes and organs at risk were contoured to develop both IMPT and VMAT plans for each patient. Two IMPT plans were designed based on the clinical target volume (CTV) with robust optimization (RO-IMPT) and the planning target volume (PTV) without RO (NonRO-IMPT), respectively. The RO-IMPT, NonRO-IMPT, and VMAT plans were normalized such that the prescription dose could cover 95% of the target volume. The dosimetric parameters of target volumes and organs at risk were evaluated, and the dosimetric characteristics of the two techniques were compared.Results:In terms of target volumes, the RO-IMPT group showed significantly lower D1%, Dmean, and homogeneity index (HI) and a significantly higher D99% of the CTV than those of the PTV in the VMAT group ( t=-8.96, -8.21, -8.13, 4.96, P<0.05). The NonRO-IMPT group showed significantly lower D1%, Dmean, and HI and a significantly higher conformity index of the PTV than those of the PTV in the VMAT group ( t=-7.75, -6.25, -6.11, 7.53, P<0.05). In terms of organs at risk, the two IMPT groups showed significantly lower values than the VMAT group for the V5- V30 and Dmean of the whole lungs, V5- V40 and Dmean of the heart, D1% and Dmean of the left anterior descending coronary artery, D1% of the spinal cord, Dmean of normal tissues, and Dmean of the skin ( t= -28.47 to -3.25, P<0.05). There was no significant difference in any other evaluation indices ( P>0.05). Conclusions:Both IMPT and VMAT can meet the clinical requirements of radiotherapy plans following breast-conserving surgery for bilateral breast cancer. IMPT has apparent advantages over VMAT in protecting organs at risk.

Objective:To construct analytical dimensions for policy texts related to the pilot work of Health Impact Assessment (HIA) system in Zhejiang Province and conduct quantitative analysis, thereby providing references for improving the pilot work.Methods:Policy texts issued by Zhejiang Province between February 11, 2018, and February 29, 2024, which involved HIA content, were selected. The policy instruments theory was employed to construct an analytical framework around the dimensions of policy instruments, policy objectives, policy actors, and the interactions between policy instruments and policy objectives, and between policy instruments and policy actors. Based on this framework, a combination of literature analysis and content analysis was used to conduct a multi-dimensional quantitative analysis of the policy texts related to the pilot work of HIA system in Zhejiang Province.Results:Fifty core policy texts were included and 1 588 codes were obtained. In terms of policy instruments, environmental-type instruments were the most widely used (852 items), with internal responsibilities and methodological measures being the most frequently used; supply-type instruments were the second most used (459 items), with mechanism improvement being the most frequently used; demand-type instruments were the least used (277 items), with multi-stakeholder participation being the most frequently used. In terms of policy objectives, the objective of system construction dominated (701 articles, accounting for 56.45%), while the proportion of policy coverage, evaluation technology, and effectiveness evaluation was relatively low. In terms of policy subjects, the Party committee and government were the main policy subjects (434 articles, accounting for 39.20%), followed by health departments and public policy-making departments, while the proportion of public health institutions and social forces was extremely low. In the interaction between policy instruments and policy objectives, policy coverage, system construction, and effectiveness evaluation objectives all responded most frequently to environmental-type instruments, while the evaluation technology objectives responded more frequently to supply-type instruments. In the interaction between policy instruments and policy subjects, the Party committee and government played a dominant role in the use of policy instruments, with the health department and public policy-making department in the middle.Conclusions:The pilot work of the HIA system in Zhejiang Province presented a " environment-driven, system-construction-priority, Party-committee-and-government-led" policy characteristic. The main challenges were the imbalanced structure of policy instruments, insufficient synergy among policy objectives, and the need for greater participation of multiple stakeholders.

Objective:To systematically evaluate the application of patient-reported outcome measures (PROMs) in adult lung transplant recipients, and to explore their clinical value in assessing quality of life following transplantation.Methods:This study was a systematic review. Relevant studies published between January 2014 and July 2024 were searched in the PubMed and OVID Medline databases using keywords such as "lung transplantation" "quality of life" "HRQoL" "health indice" "patient-reported outcome measure" "questionnaire" "profile" "scale" "score" and "survey". Only English-language articles were included. Eligible studies were those that applied PROMs to assess quality of life in adult lung transplant recipients and were approved by ethics committees. Reviews, case reports, abstracts, and studies involving transplant candidates or recipients of lung-liver or lung-kidney combined transplantation were excluded. Data extracted included basic study information, study design, participant characteristics, and PROM usage. Frequently used PROMs and lung transplant-specific PROMs were summarized, and results with clearly reported time points were analyzed.Results:A total of 63 studies were included, comprising 54 (85.7%) observational studies and 9 (14.3%) interventional studies. The majority of studies originated from the United States (18 studies, 28.6%). A total of 55 different PROMs were identified, including 30 generic and 25 disease-specific instruments. The five most frequently used PROMs were the Short Form 36 (SF-36; 30 studies, 47.6%), the EuroQol 5 Dimension (EQ-5D; 12 studies, 19.0%), the St. George's Respiratory Questionnaire (SGRQ; 11 studies, 17.5%), the Hospital Anxiety and Depression Scale (HADS; 7 studies, 11.1%), and the modified Medical Research Council dyspnea scale (mMRC; 5 studies, 7.9%). Lung transplant-specific PROMs included the Lung Transplant Quality of Life questionnaire (LT-QOL), the Lung Transplant Valued Life Activities (LT-VLA) scale, and the Pulmonary-Specific Quality of Life Scale (PQLS), which were applied in only 6 studies (9.5%). Across studies, lung transplantation was associated with significant improvements in recipients' quality of life, sustained over a follow-up period of 3 to 60 months.Conclusions:A wide range of PROMs have been employed to assess health-related quality of life in lung transplant recipients; however, transplant-specific PROMs remain relatively scarce. PROMs provide valuable insights for reflecting and dynamically monitoring long-term quality of life, supplementing evidence for clinical decision-making, and optimizing post-transplant care strategies.
