ObjectiveTo investigate the effects and underlying mechanisms of Shenqi Wenfei prescription (SQWF) on chronic obstructive pulmonary disease (COPD). MethodsA rat model of COPD with lung Qi deficiency was established using lipopolysaccharide (LPS) combined with cigarette smoke. Forty-eight SD rats were randomly divided into a blank group, a model group, low-, medium-, and high-dose SQWF groups (2.835, 5.67, 11.34 g·kg-1), and a Yupingfeng group (1.35 g·kg-1). Drug administration began on day 29 after modeling and continued for 2 weeks. The general condition of the rats was observed, and the lung function in each group was assessed. Hematoxylin-eosin (HE) staining was used to observe pathological changes in lung tissue. The proportion of inflammatory cells in bronchoalveolar lavage fluid (BALF) was measured. Apoptosis in lung tissue was examined by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL) staining. The release level of lactate dehydrogenase (LDH) in BALF was detected by a microplate assay. Reactive oxygen species (ROS) levels in lung tissue were detected using fluorescent probes. The levels of malondialdehyde (MDA), total superoxide dismutase (SOD), and reduced glutathione (GSH) in BALF were measured by biochemical methods. Ultrastructural changes in lung cells were observed via transmission electron microscopy. Double immunofluorescence staining was performed to detect the expression of thioredoxin-interacting protein (TXNIP) and nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) in lung tissue. Western blot analysis was used to detect the protein expression of TXNIP, NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), cysteinyl aspartate-specific protease-1 (Caspase-1), Caspase-1 p20, gasdermin D (GSDMD), GSDMD N-terminal active fragment (GSDMD-N), interleukin-1β (IL-1β), and IL-18 in lung tissue. Serum IL-1β and IL-18 levels were measured by ELISA. ResultsCompared with the blank group, the model group showed lassitude, fatigue, tachypnea, and audible phlegm sounds, and lung function significantly declined (P0.01). Pulmonary emphysema and inflammatory cell infiltration were obvious. The level of inflammatory cells in BALF increased significantly (P0.05). The number of TUNEL-positive cells increased (P0.01). Levels of LDH, ROS, and MDA in BALF increased significantly (P0.01), while GSH and SOD activities decreased significantly (P0.01). Lung tissue cells showed irregular morphology, swollen mitochondria, disrupted cell membranes, and abundant vesicles, i.e., pyroptotic bodies. Protein levels of TXNIP, NLRP3, ASC, Caspase-1, Caspase-1 p20, GSDMD, GSDMD-N, IL-1β, and IL-18 in lung tissue were significantly elevated (P0.01), and serum IL-1β and IL-18 levels also increased significantly (P0.01). Compared with the model group, each medication group showed alleviation of qi deficiency symptoms and improved lung function (P0.01). Pulmonary emphysema and inflammatory cell infiltration were reduced. Inflammatory cell levels decreased (P0.05). The number of TUNEL-positive cells decreased significantly (P0.01). Levels of LDH, ROS, and MDA decreased significantly (P0.05), while GSH and SOD activities significantly increased (P0.01). Morphological and structural damage in lung tissue was improved to varying degrees. Protein levels of TXNIP, NLRP3, ASC, Caspase-1, Caspase-1 p20, GSDMD, GSDMD-N, IL-1β, and IL-18 in lung tissue significantly decreased (P0.01), and serum IL-1β and IL-18 levels also decreased significantly (P0.05). ConclusionSQWF can improve lung function and alleviate inflammatory responses in COPD rats. Its mechanism may be related to regulating the ROS/TXNIP/NLRP3 pathway and inhibiting pyroptosis.

OBJECTIVE To provide reference for improving the pre-prescription review system and reducing the occurrence of medication error by analyzing the drug-related problems (DRPs) in the pre-prescription review orders of pediatric outpatient clinics using the Pharmaceutical Care Network Europe (PCNE) classification system. METHODS The data of pre-prescription review orders were retrospectively collected from outpatient department of Shanghai Children’s Medical Center, Shanghai Jiao Tong University School of Medicine from July 2022 to June 2023; DRPs in the pre-prescription review orders were classified and summarized by using the PCNE classification system (version 9.1), and then analyzed in terms of types and causes of issues, and the acceptance of interventions. RESULTS A total of 66 017 DRPs orders were included, involving 41 165 patients. The proportion of DRPs orders in children aged ≤5 years old was the highest (58.25%), followed by children aged 6-12 years old (33.52%); the department with the highest proportion of DRPs was internal medicine of pediatrics department (71.41%); the department with the highest incidence of DRPs was thoracic surgery department (9.73%); top three drug categories of DRPs orders were systemic anti- infective drugs (25.26%), Chinese patent medicines (24.74%) and respiratory drugs (22.38%). Referring to PCNE classification system, the types of DRPs mainly focused on treatment safety (64.86%); the reasons of DRPs orders mainly focused on dose selection (82.09%), of which 41.26% were due to excessive drug dosage; 92.13% of interventions could be accepted and fully executed by doctors. CONCLUSIONS DRPs orders identified by the pre-prescription review system can be effectively analyzed by using PCNE classification system. Pharmacists should focus on medication use in children aged ≤5 years old, update and develop personalized prescription review rules timely, and meet the rational needs of clinical medication for children.

With the widespread adoption of low-dose CT screening and the extensive application of high-resolution CT, the detection rate of sub-centimeter lung nodules has significantly increased. How to scientifically manage these nodules while avoiding overtreatment and diagnostic delays has become an important clinical issue. Among them, lung nodules with a consolidation tumor ratio less than 0.25, dominated by ground-glass shadows, are particularly worthy of attention. The therapeutic challenge for this group is how to achieve precise and complete resection of nodules during surgery while maximizing the preservation of the patient's lung function. The "watershed topography map" is a new technology based on big data and artificial intelligence algorithms. This method uses Dicom data from conventional dose CT scans, combined with microscopic (22-24 levels) capillary network anatomical watershed features, to generate high-precision simulated natural segmentation planes of lung sub-segments through specific textures and forms. This technology forms fluorescent watershed boundaries on the lung surface, which highly fit the actual lung anatomical structure. By analyzing the adjacent relationship between the nodule and the watershed boundary, real-time, visually accurate positioning of the nodule can be achieved. This innovative technology provides a new solution for the intraoperative positioning and resection of lung nodules. This consensus was led by four major domestic societies, jointly with expert teams in related fields, oriented to clinical practical needs, referring to domestic and foreign guidelines and consensus, and finally formed after multiple rounds of consultation, discussion, and voting. The main content covers the theoretical basis of the "watershed topography map" technology, indications, operation procedures, surgical planning details, and postoperative evaluation standards, aiming to provide scientific guidance and exploration directions for clinical peers who are currently or plan to carry out lung nodule resection using the fluorescent microscope watershed analysis method.
5.Effect of hepatitis B virus integration on functional cure
Journal of Clinical Hepatology 2025;41(1):24-29
Functional cure is currently recommended by guidelines as the ideal treatment goal for the prevention and treatment of chronic hepatitis B (CHB) in China and globally, and it is defined as sustained and undetectable serum HBsAg and HBV DNA, HBeAg clearance, and presence or absence of HBsAg seroconversion, accompanied by resolution of liver inflammation, histopathological improvements, and a significant reduction in the incidence rate of end-stage liver disease. HBV can integrate into the host genome and contribute to the continuous production of HBsAg, which can occur in the early stage of chronic HBV infection. In addition to the covalently closed circular DNA that is hard to be eliminated in liver tissue, HBsAg derived from HBV integration independent of viral replication may be the most important factor for the difficulty in achieving functional cure after antiviral therapy in patients with hepatitis B. This article reviews the research advances in HBV integration in recent years and discusses its impact on functional cure.

Journal of Prevention and Treatment for Stomatological Diseases 2025;33(2):89-99
In the field of oral medicine, 3D-printed individualized titanium mesh technology is gradually becoming an important means for the treatment of severe alveolar bone defect augmentation. This article provides a comprehensive analysis of the advantages of this technology, the evaluation of osteogenic effects, and the progress of research in clinical applications. In response to the current issue of variability in bone augmentation outcomes, this paper delves into multiple factors affecting bone augmentation effects, including individualized titanium mesh design (involving the thickness, pore size, pore shape, porosity, contour shape, selection of titanium alloy materials, and 3D printing technology), intraoperative procedures (the accuracy of placement during 3D-printed individualized titanium mesh surgery), and postoperative care (including the prevention of complications, formation of pseudoperiosteum, and stability of the titanium mesh). By integrating the clinical experience and research findings of our team, we propose a series of targeted optimization strategies, including designing, manufacturing, and clinically applying self-positioning individualized titanium meshs (positioning wings + individualized titanium meshs) to improve the positioning accuracy of the titanium mesh; propose individualized treatment processes and titanium mesh design schemes based on specific conditions of alveolar bone defects and soft tissue status; and emphasize the importance of long-term stable fixation of the titanium mesh to reduce the risk of postoperative mesh loosening and displacement. In addition, we appropriately summarize the evaluation methods for the bone augmentation effects of 3D-printed individualized titanium meshes, covering the following key indicators: (1) vertical bone augmentation and horizontal bone augmentation; (2) changes in bone contour morphology; (3) bone volume increase; (4) clinical indicators (surgical success rate, titanium mesh exposure, infection rate, and postoperative recovery); (5) aesthetic effect evaluation; (6) long-term stability; (7) radiological assessment; (8) patient satisfaction; and (9) precision of surgical operation, aiming to assist doctors in comprehensively assessing and in-depth analyzing the surgical outcomes to achieve the best therapeutic effects. The purpose of this article is to provide a reference for the optimization and clinical application of 3D-printed individualized titanium mesh technology and to lay a theoretical foundation for achieving the best osteogenic effects.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.
