Objective To explore the feasibility and reference value of allogeneic lung transplantation and postoperative monitoring in miniature pigs for lung transplantation research. Methods Two miniature pigs (R1 and R2) underwent left lung allogeneic transplantation. Complement-dependent cytotoxicity tests and blood cross-matching were performed before surgery. The main operative times and partial pressure of arterial oxygen (PaO2) after opening the pulmonary artery were recorded during surgery. Postoperatively, routine blood tests, biochemical blood indicators and inflammatory factors were detected, and pathological examinations of multiple organs were conducted. Results The complement-dependent cytotoxicity test showed that the survival rate of lymphocytes between donors and recipients was 42.5%-47.3%, and no agglutination reaction occurred in the cross-matching. The first warm ischemia times of D1 and D2 were 17 min and 10 min, respectively, and the cold ischemia times were 246 min and 216 min, respectively. Ultimately, R1 and R2 survived for 1.5 h and 104 h, respectively. Postoperatively, in R1, albumin (ALB) and globulin (GLB) decreased, and alanine aminotransferase increased; in R2, ALB, GLB and aspartate aminotransferase all increased. Urea nitrogen and serum creatinine increased in both recipients. Pathological results showed that in R1, the transplanted lung had partial consolidation with inflammatory cell infiltration, and multiple organs were congested and damaged. In R2, the transplanted lung had severe necrosis with fibrosis, and multiple organs had mild to moderate damage. The expression levels of interleukin-1β and interleukin-6 increased in the transplanted lungs. Conclusions The allogeneic lung transplantation model in miniature pigs may systematically evaluate immunological compatibility, intraoperative function and postoperative organ damage. The data obtained may provide technical references for subsequent lung transplantation research.

ObjectiveTo explore the clinical efficacy of oral administration of modified Tuoli Xiaodusan on postoperative patients with perianal abscess, and its effects on related inflammatory factors and signal transducers and activators of transcription protein 3 (STAT3)/vascular endothelial growth factor (VEGF) signaling pathways. MethodsFrom January 2023 to December 2023 in Inner Mongolia hospital of traditional Chinese medicine, 60 postoperative patients with perianal abscess who met the inclusion criteria were selected. They were divided into a treatment group and a control group using the random number table method, with 30 cases in each group. The control group received conventional treatment, while the treatment group received additional treatment with modified Tuoli Xiaodusan on the basis of the control group. The course of treatment in both groups was three weeks. On the day of operation and on the 7th, 14th and 21st day after operation, enzyme-linked immunosorbent assay (ELISA) was used to measure the expression levels of serum interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). Hematoxylin eosin (HE) staining was used to observe the pathological morphology of pathological tissue. Western blot was used to measure the levels of phosphorylated STAT3 (p-STAT3) and vascular endothelial growth factor (VEGF) proteins, and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to determine the expression level of VEGF mRNA. The clinical efficacy of the two groups was compared according to the wound pain, secretion volume score, and healing rate of patients on the 3rd, 7th, 14th, and 21st day after operation. ResultsThe total effective rate of the treatment group was higher than that of the control group (P<0.05). For intra-group comparison, the pain score of the control group decreased at each time period (P<0.05), and the healing rate increased (P<0.05). The secretion volume score decreased on the 14th and 21st days after operation (P<0.05). The pain score and secretion volume score of the treatment group decreased at each time period (P<0.05), and the healing rate increased (P<0.05). The levels of various inflammatory factors decreased in both groups (P<0.05). Compared with those on the surgical day, the levels of p-STAT3 and VEGF proteins in the wound tissue of the two groups were different on the 7th and 21st days after operation (P<0.05). There were significant differences in VEGF mRNA levels in wound tissue between the two groups at each time period (P<0.01). For inter-group comparison, on the 7th and 14th days after operation, the pain score in the treatment group was lower than that in the control group. On the 7th, 14th and 21st days after operation, the secretion volume scores and healing rate of the treatment group were better than those of the control group (P<0.05). The levels of various inflammatory factors in the treatment group were lower than those in the control group (P<0.05), and the decline rate was faster (P<0.05). On the 7th day after operation, the levels of p-STAT3, VEGF protein, and VEGF mRNA in the wound tissue of the treatment group were higher than those in the control group (P<0.05). HE staining showed that the inflammatory cell infiltration in the treatment group decreased faster. The cell arrangement was more orderly, and new blood vessel lumens were visible. There were no abnormalities in the safety observation indexes of all patients during the study period. ConclusionModified Tuoli Xiaodusan can relieve wound pain after perianal abscess surgery, reduce secretions, and improve wound healing rate. The mechanism may be reducing the levels of serum IL-1β, IL-6, and TNF-α, reducing the inflammatory response of the wound, upregulating the expression of p-STAT3 and VEGF proteins, and stimulating the STAT3/VEGF signaling pathway, thereby accelerating angiogenesis and promoting wound healing.

To explore the advantages of traditional Chinese medicine (TCM) and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications (DMC), refine key pathophysiological insights and treatment principles, and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine, hosted by the China Association of Chinese Medicine, was held in Beijing, 2024. Experts in TCM, Western medicine, and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis, diagnostic and treatment challenges, and mechanism research related to DMC, ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development, research prioritization, and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM, strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

Hygroscopicity research has long been a key focus and hot topic in Chinese materia medica(CMM). Elucidating hygroscopic mechanisms plays a vital role in formulation design, process optimization, and storage condition selection. Hygroscopic models serve as essential tools for characterizing CMM hygroscopic mechanisms, with various types available. The double exponential model is a kinetic mathematical model constructed based on the law of conservation of energy and Fick's first law of diffusion, tailored to the physical properties of CMM extracts. In recent years, this model has been extensively applied to simulate the dynamic moisture absorption behavior of CMM extracts and solid dosage forms under varying humidity conditions. It has revealed the correlation between moisture absorption kinetic parameters and material properties, offering a new perspective for characterizing the moisture uptake behavior of CMM. This paper systematically reviews the application progress of this model in the field of CMM, analyzes its advantages, disadvantages, and challenges in this domain, and explores its potential application trends in other fields. It aims to provide references for elucidating the moisture absorption mechanisms of CMM and researching moisture-proofing technologies, while also offering insights for its broader application in food and polymer materials.

Objective To explore the diagnostic value of exhaled volatile organic compounds (VOCs) for cystic fibrosis (CF). Methods A systematic search was conducted in PubMed, EMbase, Web of Science, Cochrane Library, CNKI, Wanfang, VIP, and SinoMed databases up to August 7, 2024. Studies that met the inclusion criteria were selected for data extraction and quality assessment. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS), and the risk of bias and applicability of included prediction model studies were assessed by the prediction model risk of bias assessment tool (PROBAST). Results A total of 10 studies were included, among which 5 studies only identified specific exhaled VOCs in CF patients, and another 5 developed 7 CF risk prediction models based on the identification of VOCs in CF. The included studies reported a total of 75 exhaled VOCs, most of which belonged to the categories of acylcarnitines, aldehydes, acids, and esters. Most models (n=6, 85.7%) only included exhaled VOCs as predictive factors, and only one model included factors other than VOCs, including forced expiratory flow at 75% of forced vital capacity (FEF75) and modified Medical Research Council scale for the assessment of dyspnea (mMRC). The accuracy of the models ranged from 77% to 100%, and the area under the receiver operating characteristic curve ranged from 0.771 to 0.988. None of the included studies provided information on the calibration of the models. The results of the Prediction Model Risk of Bias Assessment Tool (PROBAST) showed that the overall bias risk of all predictive model studies was high, and the overall applicability was unclear. Conclusion The exhaled VOCs reported in the included studies showed significant heterogeneity, and more research is needed to explore specific compounds for CF. In addition, risk prediction models based on exhaled VOCs have certain value in the diagnosis of CF, but the overall bias risk is relatively high and needs further optimization from aspects such as model construction and validation.

Objective:
To explore the impacts of coal mine dust on lung function in rats, so as to provide the basis for the early prevention and treatment of coal worker's pneumoconiosis.
Methods:
Seventy-two SPF-grade 8-week-old male Sprague-Dawley rats were randomly divided into the coal dust group, the coal-silica dust group, the silica dust group and the control group. The rats in the first three groups of rats were administered 1 mL corresponding dust suspension into the lungs using non-exposure tracheal instillation, while the rats in the control group were administered 1 mL normal saline. Respiratory rate (f), forced vital capacity (FVC), peak expiratory flow (PEF) and dynamic pulmonary compliance (Cdyn) were measured at 1, 3 and 6 months after dust exposure. Lung tissues were collected to measure reactive oxygen species (ROS) and adenosine triphosphate (ATP) levels using corresponding ELISA kits and ATP assay kits, respectively. The relative mRNA expressions of peroxisome proliferators-activated receptor gamma coactivator 1-alpha (PGC-1α) and mitochondrial transcription factor A (TFAM) were detected using real-time fluorescent quantitative polymerase chain reaction assay. The relative protein expressions of PGC-1α and TFAM were detected using Western blotting.
Results:
There was no interaction between dust type and exposure duration on f (P>0.05), but there were interactions on FVC, PEF and Cdyn (all P<0.05). Compared with the control group at 6 months after dust exposure, the f of the rats in the silica dust group were increased, while the FVC and PEF of the rats in the coal-silica dust and silica dust groups were decreased, and Cdyn of the rats in the coal dust, coal-silica dust and silica dust groups were decreased (all P<0.05). There were interactions between dust type and exposure duration on ROS and ATP levels, the relative mRNA and protein expressions of PGC-1α and TFAM (all P<0.05). Compared with the control group at 3 and 6 months after dust exposure, the ROS levels in the rats in the coal dust, coal-silica dust and silica dust groups were increased, while the ATP levels, the relative mRNA and protein expressions of PGC-1α and TFAM were decreased (all P<0.05).
Conclusion
The lung function impairment in rats caused by different types of coal mine dust is related to PGC-1α-mediated mitochondrial biogenesis dysfunction, which leads to increased ROS levels, decreased ATP and TFAM levels.

Objective:
To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes.
Methods:
The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model.
Results:
A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915).
Conclusion
The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

Objective:
To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures.
Methods:
Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC).
Results:
A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively.
Conclusions
The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Portal vein embolization (PVE) can induce atrophy of the embolized lobe and compensatory regeneration of the non-embolized lobe. However, due to inadequate regeneration of future liver remnant (FLR) after PVE, some patients remain unsuitable for hepatectomy after PVE. In recent years, liver venous deprivation (LVD), which combines PVE with hepatic vein embolization (HVE), has induced enhanced FLR regeneration. Compared with associating liver partition and portal vein ligation for staged hepatectomy (ALPPS), LVD triggers faster and more robust FLR regeneration, with lower incidence rate of postoperative complications and mortality rate. By reviewing related articles on LVD, this article introduces the effectiveness of LVD and analyzes the differences and safety of various technical paths, and it is believed that LVD is a safe and effective preoperative pretreatment method.

ObjectiveTo investigate the effects of Dihuang Yinzi on the cognitive function in the mouse model of learning and memory impairments induced by scopolamine (SCOP) and explore the treatment mechanism. MethodsA mouse model of learning and memory impairment was induced by intraperitoneal injection of SCOP. Sixty male C57BL/6J mice were randomized into six groups: control (0.9% NaCl, n=10), model (SCOP 1 mg·kg-1·d-1, n=10), low-, medium-, and high-dose Dihuang Yinzi (SCOP 1 mg·kg-1·d-1 + Dihuang Yinzi 5.5, 11.0, and 22.0 g·kg-1·d-1, n=10), and donepezil (SCOP 1 mg·kg-1·d-1 + donepezil 0.84 mg·kg-1·d-1, n=10). Mice were administrated with corresponding drugs for 6 weeks. Modeling started in the 4th week, and mice in other groups except the control group were injected with SCOP intraperitoneally 40 min after daily gavage. Behavioral testing began in the 5th week, 30 min after modeling each day. The Morris water maze and novel object recognition tests were carried out to evaluate the spatial learning and memory function of mice. Nissl staining was employed to observe the survival of neurons and Nissl bodies in the hippocampal CA1 region. Western blot was employed to determine the protein levels of silent information regulator 2 (SIRT2), α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid (AMPA) receptor 1 (GluA1), protein kinase A (PKA), cAMP response element-binding protein (CREB), phosphorylated-CREB (p-CREB), postsynaptic density protein 95 (PSD95), growth-associated protein-43 (GAP-43), and synaptophysin (SYN) in the hippocampus. Immunofluorescence was used to detect the expression of doublecortin (DCX) in the hippocampal dentate gyrus (DG) region. ResultsCompared with the control group, the model group showed impaired learning and memory (P<0.01), obvious neuronal damage in the hippocampal CA1 region, a reduction in neuron survival (P<0.01), a decrease in DCX expression in the hippocampal DG region (P<0.01), down-regulated proteins levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 in the hippocampal tissue (P<0.05, P<0.01), and an up-regulated protein level of SIRT2 (P<0.01). Compared with the model group, the medium- and high-dose Dihuang Yinzi groups and the donepezil group showed improvements in learning and memory (P<0.05, P<0.01), while the low-, medium-, and high-dose Dihuang Yinzi groups and the donepezil group had increased neuron survival (P<0.05, P<0.01). The medium-dose Dihuang Yinzi group and the donepezil group showed increased DCX expression (P<0.05, P<0.01). The medium- and high-dose Dihuang Yinzi groups and the donepezil group showed up-regulation in the protein levels of GluA1, PKA, p-CREB/CREB, PSD95, SYN, and GAP-43 (P<0.05, P<0.01) and down-regulation in the protein level of SIRT2 (P<0.01). ConclusionDihuang Yinzi can improve the cognitive function in the mouse model of learning and memory impairments induced by SCOP by inhibiting the upregulation of SIRT2, activating the PKA/CREB signaling pathway, improving synaptic plasticity, and reducing hippocampal neuronal damage.
