ObjectiveTo investigate the migration and distribution characteristics of chemical constituents in blood and hippocampal tissues before and after vinegar processing of Citri Reticulatae Pericarpium Viride（CRPV）， and to explore the potential material basis and mechanisms underlying their regulatory effects on emotional disorders by comparing the effects of raw and vinegar-processed products of CRPV. MethodsUltra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS/MS） was employed to characterize and identify the chemical constituents of raw and vinegar-processed products of CRPV extracts， as well as their migrating components in blood and hippocampal tissues after oral administration. Reference standards， databases， and relevant literature were utilized for compound annotation， with data processing performed using PeakView 1.2 software. Seventy male C57BL/6 mice were randomly divided into seven groups， including the blank group， model group， diazepam group（2.5 mg·kg^-1）， raw CRPV low/high dose groups（0.6， 1.2 g·kg^-1）， and vinegar-processed CRPV low/high dose groups（0.6， 1.2 g·kg^-1）， with 10 mice per group. Except for the blank group， all other groups underwent chronic restraint stress（2 h·d^-1） for 20 d. Each drug-treated group received oral administration at the predetermined dose starting 10 d after modeling， with a total treatment duration of 10 d. Following model-based drug administration， mice underwent open-field， forced swimming， and elevated plus maze tests. After anesthesia with isoflurane， whole brains were collected from each group of mice， and hippocampi were dissected. Reactive oxygen species（ROS） level in hippocampal tissues was quantified by enzyme-linked immunosorbent assay（ELISA）. Hematoxylin-eosin（HE） staining was used to observe hippocampal tissue morphology. Immunofluorescence was performed to detect neuronal nuclei（NeuN） and peroxisome proliferator-activated receptor alpha（PPARα） expressions in hippocampal tissue. Then， pharmacodynamic evaluations were conducted to assess the effects of raw and vinegar-processed CRPV on mood disorders， exploring the potential mechanisms. ResultsVinegar processing caused significant changes in the chemical composition of CRPV， with 18 components showing increased relative content and 35 components showing decreased relative content. The primary changes occurred in flavonoid compounds， including 20 flavonoids， 20 flavonoid glycosides， 3 triterpenes， 3 phenolic acids， 1 alkaloid， and 6 other compounds. Twenty-one components were detected in blood（15 methoxyflavones， 4 flavonoid glycosides， and 2 phenolic acids）， with 17 shared between raw and vinegar-processed CRPV. Seven components reached hippocampal tissues（all common to both forms）. In regulating emotional disorders， Vinegar-processed CRPV exhibited superior antidepressant-like effects compared to raw products. HE staining revealed that both treatments improved hippocampal neuronal morphology， particularly in the damaged CA1 and CA3 regions. Immunofluorescence and ELISA analyses demonstrated that both raw and vinegar-processed CRPV significantly modulated NeuN and PPARα expressions in hippocampal tissue while alleviating oxidative stress induced by excessive ROS（P<0.05）. ConclusionThe chemical composition of CRPV undergoes changes after vinegar processing， but the migrating components in blood and hippocampus are primarily methoxyflavonoids. These components may serve as the potential material basis for activating the PPARα pathway， thereby negatively regulating ROS generation in the hippocampus， reducing oxidative stress， and promoting the development of NeuN-positive neurons. These findings provide experimental evidence for enhancing quality standards， pharmacodynamic material research， and active drug development of raw and vinegar-processed CRPV.

Objective: To evaluate the practical effectiveness of confidential unit exclusion (CUE) in ensuring blood safety in Zhengzhou, analyze its application characteristics and existing problems, and provide a basis for optimizing blood safety management strategies. Methods: A retrospective analysis was conducted on CUE data handled by Henan Red Cross Blood Center from January 2019 to December 2024. Parameters such as the number of cases, demographic characteristics, reasons for exclusion, and time of report were statistically analyzed and compared with those of non-CUE. Results: From 2019 to 2024, the CUE reporting rate in Zhengzhou was 0.002 6% (40/1 547 666). CUE donors were predominantly male (65.00%, 26/40), aged 18-34 years (47.50%, 19/40), had college degree orabove (50.00%, 20/40), and were employees of enterprises or public institutions (32.50%, 13/40). Among the 40 CUE blood units, only one was reactive for anti-TP, while all others were qualified. The main reasons for CUE were recent vaccination (32.50%, 13/40), medical conditions unsuitable for donation (27.50%, 11/40), and high-risk sexual behavior (17.50%, 7/40). A total of 70.00% of reports occurred within 24 hours after donation, during which none of the corresponding blood units had been released; all units reported after more than 7 days had already been issued for clinical use, with no adverse transfusion reactions reported upon follow-up. Conclusion: The confidential unit exclusion program has played an active role in establishing a supplementary information feedback channel for blood donors. The procedure can be optimized by strengthening interactive communication and confirmation before donation, improving the accuracy of donors' self-assessment, and expanding convenient and rapid information-based reporting channels.

Kui was first recorded in The Rites of Zhou and is the earliest domesticated wild vegetable in China. In the Qi Min Yao Shu, Kui was called “the master of all vegetables” and has a long history of application in China. As a medicine, Kuizi was first recorded in Shen Nong’s Herbal Classic, which has a history of more than 2 000 years of medicinal use and a long history of clinical application. By researching the ancient and modern herbal literature, the first herbs texts of Kui were examined, various recorded texts, confused products and the history of the original medicinal use were clarified. It was concluded that the ancient herbal texts recorded the base plant of Kui as Malva verticillata L. belonging to family Malvaceae, which provided scientific basis for the development and utilization of Kui.

Non-alcoholic fatty liver disease （NAFLD） is one of the most prevalent forms of liver diseases globally. Its progression can lead to cirrhosis and end-stage liver disease， and there is currently a lack of effective pharmacological treatments. Adenosine monophosphate-activated protein kinase （AMPK）， as a regulatory hub for maintaining cellular energy homeostasis， can coordinate key cellular processes such as adipogenesis， glucose metabolism， and mitochondrial functions. Its activation exerts metabolic regulatory effects through pathways including inhibiting lipogenesis， enhancing mitochondrial β-oxidation， regulating inflammation and oxidative stress， and promoting autophagy. Accordingly， AMPK emerges as a potential target for the prevention and treatment of NAFLD. Traditional Chinese Medicine （TCM）， with low toxicity， high accessibility， and multi-component， multi-target synergistic effects， has demonstrated unique value in NAFLD treatment， particularly showing notable advantages in regulating the AMPK signaling pathway. Sichuan is known as the treasure house of TCM， and the active components of its authentic medicinal materials such as Coptidis Rhizoma not only reflect regional characteristics in AMPK signaling regulation but also form a multi-level metabolic regulatory network through crosstalk with pathways such as sirtuin 1 （SIRT1） and peroxisome proliferator-activated receptor α （PPARα）. They can achieve specific regulation by directly activating AMPK and modulating upstream and downstream targets， exerting prominent effects in ameliorating hepatic steatosis and inflammation. This study systematically reviews the research findings on TCM for the prevention and treatment of NAFLD over the past five years， elaborating the mechanisms by which TCM treats NAFLD through regulating the AMPK signaling pathway. It aims to provide new perspectives and references for clinical diagnosis and treatment， basic research， and drug development.

The core pathogenesis of Morvan syndrome （MoS） lies in five zang （脏） organs depletion and internal wind stirring， with the involvement of phlegm， heat， and stasis. Root deficiency leads to wind stirring， which further generates phlegm， transforms into heat， and causes stasis. The disease is divided into three stages for treatment. In the acute stage， branch excess predominates with intermingled wind， phlegm， heat， and stasis， for which treatment should focus on extinguishing wind， resolving phlegm， clearing heat， and removing stasis. In the remission stage， both root deficiency and branch excess are present， and treatment should address both the root cause and the manifestations simultaneously. In the recovery stage， root deficiency predominates， and treatment should focus on reinforcing healthy qi.

Based on the theory of collateral disease， the treatment of late-stage sequela of cerebrovascular disease is considered to be primarily associated with deficiency and obstruction of cerebral collaterals and dysfunction of the spirit mechanism. Therefore， the fundamental therapeutic principle is to unblock and supplement the brain collaterals. Clinically， the late-stage sequelae of cerebrovascular disease are classified into four patterns， which are malnourishment， deficiency-heat， stasis obstruction， and phlegm clouding of brain collaterals. These are treated respectively with Tiansui Tongqiao Decoction （填髓通窍汤） to supplement essence and nourish the brain through moistening， unblocking and supplementing， Qingnao Touluo Decoction （清脑透络汤） to enrich yin， regulate spirit， and unblock collaterals through clearing and penetrating， Yiqi Tongluo Decoction （益气通络汤） to tonify qi and resolve stasis while softening tendons and unblocking collaterals， and Xinrun Touqiao Beverage （辛润透窍饮） to unblock and tonify yin and yang while unblocking the collaterals through acrid-moistening medicinals. Flexible modification of prescriptions according to individual symptoms was applied， resulting in favorable therapeutic outcomes.

Metabolic dysfunction-associated fatty liver disease （MAFLD） is a chronic liver condition closely associated with dysregulated lipid metabolism， with the central pathological event of mitochondrial dysfunction in hepatocytes. The mitochondrial calcium uniporter （MCU） complex is a key molecular apparatus regulating mitochondrial calcium （mtCa²⁺） homeostasis， and mtCa²⁺ overload due to its dysfunction plays a critical role in the progression of MAFLD. This article systematically elaborates on the pathogenesis of MAFLD， with a particular focus on how the central signaling axis of “MCU complex dysfunction-mtCa²⁺ overload” drives the disease progression of MAFLD by disrupting energy metabolism， activating the adenosine monophosphate-activated protein kinase signaling pathway， triggering the NOD-like receptor protein 3 inflammasome， and inducing cell death. It also points out that traditional Chinese medicine can exert an interventional effect on multiple downstream pathways through various targets and has shown unique advantages and a significant potential in alleviating MAFLD by maintaining mitochondrial homeostasis and targeting the MCU complex， and therefore， it is expected to provide new strategies for the prevention and treatment of MAFLD.

ObjectiveTo screen for and validate key differentially expressed proteins in serum of patients with metabolic dysfunction‑associated fatty liver disease （MAFLD）， and to provide a basis for identifying diagnostic biomarkers and developing intervention strategies for this disease. MethodsA total of 20 patients who were diagnosed with MAFLD in the third affiliated hospital of Chengdu University of Traditional Chinese Medicine from December 2024 to January 2025 were enrolled as MAFLD group， and 20 healthy controls were enrolled as HC group. Demographic data and serum biochemical parameters were collected from both groups. Data-independent acquisition （DIA） quantitative proteomics was used to measure the relative expression levels of serum proteins， and related methods were used to obtain significantly differentially expressed proteins， including the gene ontology functional enrichment analysis， the Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis， protein-protein interaction （PPI） network， Hub node interaction， and weighted gene co-expression network analysis （WGCNA）. Rats were given a high-fat diet to establish a model of MAFLD， and randomly assigned to the control group and model group. Serum biochemical parameters and inflammatory factors were measured， liver histopathological changes were observed， and the protein expression levels of MER proto-oncogene tyrosine kinase （MERTK） and matrix metalloproteinase-9 （MMP-9） in liver tissue were verified. The independent-samples t test was used for comparison of normally distributed continuous data between groups， while the Mann-Whitney U test was used for comparison of non-normally distributed continuous data or data with heterogeneity of variance between groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsCompared with the HC group， the MAFLD group had significant increases in the serum levels of aspartate aminotransferase （t=-7.348， P<0.05）， alanine aminotransferase （Z=5.088， P<0.05）， alkaline phosphatase （t=-3.943， P<0.05）， triglyceride （Z=2.070， P<0.05）， and high-density lipoprotein cholesterol （t=3.867， P<0.05）. A total of 3 559 proteins were identified by DIA serum proteomics， among which 160 differentially expressed proteins were mainly enriched in pathways including metabolic disorders， immune inflammatory response， and extracellular matrix remodeling. The PPI network and the Hub node analysis showed that serpin family E member 1， MMP-9， and intercellular cell adhesion molecule-1 were core regulatory proteins. WGCNA showed that the MEyellow module was significantly positively correlated with MAFLD phenotype （cor=0.55， P<0.001）， which was functionally enriched in the efferocytosis pathway. MERTK （P<0.001） and MMP-9 （P<0.001） showed the most significant differential expression in this module. A rat model of MAFLD was successfully established using a high-fat diet， and compared with the control group， the model group had enlarged， yellowish， and greasy liver and disordered structure of hepatic lobules， hepatocyte fatty degeneration， and inflammatory cell infiltration based on HE staining， as well as massive lipid droplet deposition based on oil red O staining， while no obvious fibrous cords were observed in Masson staining. Compared with the control group， the model group had significant increases in the serum levels of aspartate aminotransferase （t=-5.148， P<0.05）， alanine aminotransferase （t=-5.663， P<0.05）， total bilirubin （t=-13.061， P<0.05）， triglyceride （Z=-2.722， P<0.05）， total cholesterol （t=3.588， P<0.05）， and tumor necrosis factor-α （t=-16.741， P<0.05）， as well as significant increases in the protein expression levels of MERTK （t=-11.448， P<0.001） and MMP-9 （t=-10.875， P<0.001） in liver tissue. ConclusionMMP-9 and MERTK are abnormally expressed in MAFLD and may be used as potential diagnostic biomarkers for this disease.

Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.
