Objective:
The effects and molecular mechanisms of micheliolide on cytokine expression in myeloproliferative neoplasm cell lines were explored based on the signal transducer and activator of transcription 3 (STAT3)/nuclear factor-kappa B (NF-κB) signaling pathways.
Methods:
The UKE-1 and SET-2 cell lines were investigated, and micheliolide concentrations were screened using the CCK-8 assay. The UKE-1 and SET-2 cells were divided into the control and micheliolide-treated groups at concentrations of 2.5, 5.0, and 10.0 μmol/L. Each group received 1 mL of micheliolide solution at final concentrations of 2.5, 5.0, and 10.0 μmol/L, respectively, whereas the control group only received an equal volume of culture medium. The inhibition rates of interleukin-1β(IL-1β), tumor necrosis factor-α (TNF-α), and chemokine ligand 2 (CCL2) mRNA expression in cells from each group were detected using real-time fluorescent PCR (RT-PCR). Western blotting was used to measure STAT3 and phosphorylated STAT3 (p-STAT3) protein expression levels in cells from each group. Reversal experiments with reduced glutathione and dithiothreitol were performed using UKE-1 cells, which were divided into the control group, micheliolide, micheliolide + glutathione, micheliolide + dithiothreitol, and glutathione + dithiothreitol groups. Western blotting was used to detect the STAT3 and p-STAT3 protein expression levels in the cells of each group. UKE-1 cells were stimulated with TNF-α (5 μg/L) to replicate a pathological model of excessive cytokine secretion. Subsequently, UKE-1 cells were divided into the control, model, and three micheliolide-treated groups at concentrations of 2.5, 5.0, and 10.0 μmol/L. RT-PCR was used to measure the indicators above. An enzyme-linked immunosorbent assay (ELISA) was used to detect the CCL2 content in the cell culture media of each group. Western blotting was performed to assess the protein expression levels of STAT3, p-STAT3, and proteins related to the NF-κB signaling pathway.
Results:
Compared with the control group, the proliferation inhibition rates of UKE-1 cells at 24, 48, and 72 h increased in the micheliolide-treated groups at concentrations of 2.5, 5.0, 10.0, and 20.0 μmol/L. Similarly, the proliferation inhibition rates of SET-2 at 48 and 72 h increased in the micheliolide-treated groups at concentrations of 5.0, 10.0, and 20.0 μmol/L (P<0.05). Concentrations of 2.5, 5.0, and 10.0 μmol/L were selected for further studies to exclude the potential influence of high micheliolide concentrations on subsequent result owing to reduced cell numbers. Compared with the control group, the inhibition rates of TNF-α mRNA expression in UKE-1 and SET-2 cells increased in the micheliolide-treated groups at concentrations of 2.5, 5.0, and 10.0 μmol/L. Similarly, the inhibition rates of IL-1β mRNA expression in UKE-1 and SET-2 cells also increased in the micheliolide-treated groups at concentrations of 5.0 and 10.0 μmol/L. Additionally, the inhibition rate of CCL2 mRNA expression in UKE-1 and SET-2 cells increased in the micheliolide-treated group at a concentration of 10 μmol/L (P<0.05). Compared with the model group, the inhibition rates of TNF-α, IL-1β, and CCL2 mRNA expression in UKE-1 cells increased in the micheliolide-treated groups at concentrations of 2.5, 5.0, and 10.0 μmol/L after stimulation with TNF-α (P<0.05). ELISA showed that compared with the control group, the CCL2 content in UKE-1 cells increased in the model group. Compared with the model group, the CCL2 content in UKE-1 cells decreased in the micheliolide-treated groups at concentrations of 2.5, 5.0, and 10.0 μmol/L (P<0.05). Western blotting showed that compared with the control group, the p-STAT3 protein expression levels in UKE-1 and SET-2 cells were downregulated in the micheliolide-treated groups at concentrations of 5.0 and 10.0 μmol/L, and the protein expression level of STAT3 in SET-2 was also downregulated (P<0.05). Compared with the control group, the p-STAT3 expression level in UKE-1 cells decreased in the micheliolide group in the reductive glutathione and dithiothreitol reversal experiments. Compared with the micheliolide group, the p-STAT3 protein expression levels in UKE-1 cells increased in the micheliolide + dithiothreitol and micheliolide + glutathione groups (P<0.05). Compared with the control group, the model group showed increased p-STAT3, p-IκKα/β, p-IκBα, and p-NF-κB p65 protein expression and decreased IκBα protein expression after stimulation with TNF-α. Compared with the model group, the micheliolide-treated groups showed decreased p-IκKα/β, p-IκBα, p-STAT3, and p-NF-κB p65 protein expression at concentrations of 2.5, 5.0, and 10.0 μmol/L, whereas the micheliolide-treated groups showed increased IκBα protein expression at concentrations of 5.0 and 10.0 μmol/L (P<0.05).
Conclusion
Micheliolide potently suppresses IL-1β, TNF-α, and CCL2 mRNA expression in UKE-1 and SET-2 cells, as well as CCL2 secretion by UKE-1 cells, which may be associated with STAT3 phosphorylation suppression and NF-κB signaling pathway activation.

ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

ObjectiveTo explore the data standard system of electronic medical records in the field of rehabilitation, focusing on the terminology and coding standards, data structure, and key content categories of rehabilitation electronic medical records. MethodsBased on the Administrative Norms for the Application of Electronic Medical Records issued by the National Health Commission of China, the electronic medical record standard architecture issued by the International Organization for Standardization and Health Level Seven (HL7), the framework of the World Health Organization Family of International Classifications (WHO-FICs), Basic Architecture and Data Standards of Electronic Medical Records, Basic Data Set of Electronic Medical Records, and Specifications for Sharing Documents of Electronic Medical Records, the study constructed and organized the data structure, content, and data standards of rehabilitation electronic medical records. ResultsThe data structure of rehabilitation electronic medical records should strictly follow the structure of electronic medical records, including four levels (clinical document, document section, data set and data element) and four major content areas (basic information, diagnostic information, intervention information and cost information). Rehabilitation electronic medical records further integrated information related to rehabilitation needs and characteristics, emphasizing rehabilitation treatment, into clinical information. By fully applying the WHO-FICs reference classifications, rehabilitation electronic medical records could establish a standardized framework, diagnostic criteria, functional description tools, coding tools and terminology index tools for the coding, indexing, functional description, and analysis and interpretation of diseases and health problems. The study elaborated on the data structure and content categories of rehabilitation electronic medical records in four major categories, refined the granularity of reporting rehabilitation content in electronic medical records, and provided detailed data reporting guidance for rehabilitation electronic medical records. ConclusionThe standardization of rehabilitation electronic medical records is significant for improving the quality of rehabilitation medical services and promoting the rehabilitation process of patients. The development of rehabilitation electronic medical records must be based on the national and international standards. Under the general electronic medical records data structure and standards, a rehabilitation electronic medical records data system should be constructed which incorporates core data such as disease diagnosis, functional description and assessment, and rehabilitation interventions. The standardized rehabilitation electronic medical records scheme constructed in this study can support the improvement of standardization of rehabilitation electronic medical records data information.

ObjectiveTo explore the standardization of inpatient rehabilitation medical record summary sheet, encompassing its structure, content and data standards, to enhance the standardization level of inpatient rehabilitation medical record summary sheet, improve data reporting quality, and provide accurate data support for medical insurance payment, hospital performance evaluation, and rehabilitation discipline evaluation. MethodsBased on the relevant specifications of the National Health Commission's Basic Norms for Medical Record Writing, Specifications for Sharing Documents of Electronic Medical Records, and Quality Management and Control Indicators for Inpatient Medical Record Summary Sheet (2016 Edition), this study analyzed the structure and content of the inpatient rehabilitation medical record summary sheet. The study systematically applied the three major reference classifications of the World Health Organization Family of International Classifications, International Classification of Diseases (ICD-10/ICD-11, ICD-9-CM-3), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), for disease diagnosis, functional description and assessment, and rehabilitation intervention, forming a standardized terminology system and coding methods. ResultsThe inpatient rehabilitation medical record summary sheet covered four major sections: inpatient information, hospitalization information, diagnosis and treatment information, and cost information. ICD-10/ICD-11 were the standards and coding tools for admission and discharge diagnoses in the inpatient rehabilitation medical record summary sheet. The three functional assessment tools recommended by ICD-11, the 36-item version of World Health Organization Disability Assessment Schedule 2.0, Brief Model Disability Survey and Generic Functioning domains, as well as ICF, were used for rehabilitation functioning assessment and the coding of outcomes. ICHI Beta-3 and ICD-9-CM-3 were used for coding surgical procedures and operations in the medical record summary sheet, and also for coding rehabilitation intervention items. ConclusionThe inpatient rehabilitation medical record summary sheet is a summary of the relevant content of the rehabilitation medical record and a tool for reporting inpatient rehabilitation data. It needs to be refined and optimized according to the characteristics of rehabilitation, with necessary data supplemented. The application of ICD-11/ICD-10, ICF and ICHI Beta-3/ICD-9-CM-3 classification standards would comprehensively promote the accuracy of inpatient diagnosis of diseases and functions. Based on ICD-11 and ICF, relevant functional assessment result data would be added, and ICHI Beta-3/ICD-9-CM-3 should be used to code rehabilitation interventions. Improving the quality of rehabilitation medical records and inpatient rehabilitation medical record summary sheet is an important part of rehabilitation quality control, and also lays an evidence-based data foundation for the analysis and application of inpatient rehabilitation medical record summary sheet.

Objective To analyze the differences of free and esterified oxo-eicosatetraenoic acids (oxo-ETEs) in blood cells and plasma from arterial and venous blood in hemodialysis (HD) patients. Methods Arterial and venous blood samples from 12 patients with end-stage renal disease (ESRD) before and after HD treatment at Charité – Universitätsmedizin Berlin, Germany, from June to December 2020 were collected. The esterified and free oxo-ETEs derived from arachidonic acid in blood cells and plasma were measured by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Results Neither esterified nor free oxo-ETEs in blood cells displayed significant arteriovenous differences before and after HD. HD predominantly affected the metabolic levels of esterified and free oxo-ETEs in plasma. HD reduced the arteriovenous differences of esterified 12-oxo-ETE, free 15-oxo-ETE, and free 5-oxo-ETE in plasma, while raised the arteriovenous differences of esterified 15-oxo-ETE. Conclusions The oxo-ETEs in blood cells are relatively well-stabilized responding to HD treatment, whereas arteriovenous differences of free and esterified oxo-ETEs in plasma are present and active in response to HD treatment, potentially contributing to the cardiovascular disease.

Objective :
To investigate the effects of resveratrol(Res) on fibroblast-like synoviocytes(FLS) in patients with rheumatoid arthritis(RA), and to explore the possible mechanism of Res inhibiting the release of inflammatory factors from FLS.
Methods :
FLS from RA patients were culturedin vitroand treated with different concentrations of Res(0, 20, 40, 80, 160, 320 μmol/L). The viability of FLS cells was detected by CCK-8 assay after 12 and 24 h. The contents of inflammatory factor interleukin-6(IL-6) and tumor necrosis factor-α(TNF-α) in cell supernatant were detected by ELISA. The expression levels of cyclic guanosine monophosphate-adenosine monophosphate synthase(cGAS) and stimulator of interferon gene(STING) were measured by Western blot; After lentivirus infection with FLS caused the cells to overexpress cGAS, the cells were divided into Control group(blank control), cGAS group(cGAS overexpression), Res+cGAS group(Res 160 μmol/L+cGAS overexpression) and Res group(Res 160 μmol/L). The expression level of STING protein in cells of each group was determined by Western blot, the viability of FLS cells in each group was detected by CCK-8, and the contents of inflammatory factor IL-6 and TNF-α in the supernatant of cells of each group were detected by ELISA method.
Results :
The results of CCK-8 experiment showed that under 40, 80, 160 μmol/L Res treatment, FLS viability decreased significantly after 24 h compared with blank control group(P<0.01). ELISA results showed that the contents of IL-6 and TNF-α in cell supernatant were also significantly decreased after treatment with Res of 40, 80 and 160 μmol/L(P<0.01). Meanwhile, Western blot results showed that Res could significantly decrease the protein expression levels of STING and cGAS in FLS cells after treatment of 40, 80 and 160 μmol/L(P<0.05,P<0.01). Compared with the Control group, the expression level of STING protein in FLS increased after overexpression of cGAS(P<0.05); compared with the Res group, the content of inflammatory factors in the supernatant of FLS and the expression level of STING protein in FLS significantly increased after overexpression of cGAS(P<0.01,P<0.05).
Conclusion
The appropriate concentration of Res can inhibit the release of inflammatory cytokines in FLS cells, which may be related to the blocking of cGAS-STING signaling pathway.

ObjectiveTo explore the mechanism by which the ethanol extract of Epimedium brevicornu (EEBM) intervenes in mesenchymal adipose-derived stem cells (ADSCs) to delay aging in castrated rats. MethodsForty-five 3-month-old SPF female SD rats were ovariectomized and randomly divided into model group, ADSCs treatment group, and ADSCs groups treated with low, medium, and high concentrations of EEBM (1, 50, 100 μg·L-1), referred to as the AE low, medium, and high concentration groups, with 9 rats in each group. After tail vein injection of 200 μL of the corresponding stem cell suspension, aging-related indicators including cyclin-dependent kinase inhibitor (p21), tumor suppressor gene (p53), interleukin-6 (IL-6), interleukin-8 (IL-8), superoxide dismutase (SOD), malondialdehyde (MDA), B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cysteine-aspartic acid protease-3 (Caspase-3), and lipofuscin were measured using enzyme-linked immunosorbent assay (ELISA) and Western blot. ResultsCompared with the model group, the IL-6 content in the AE low, medium, and high concentration groups was significantly decreased (P<0.05). Lipofuscin, MDA, and IL-8 levels in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.01), while SOD content was significantly increased (P<0.05, P<0.01). Compared with the ADSCs treatment group, lipofuscin and IL-8 levels in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01). The MDA content was significantly decreased in the AE medium concentration group (P<0.01). Compared with the model group, protein levels of p21, p53, Bax, and Caspase-3 in the ADSCs treatment group and AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), while the Bcl-2 protein level was significantly increased (P<0.01). Compared with the ADSCs treatment group, protein levels of p21, p53, Bax, and Caspase-3 in the AE low, medium, and high concentration groups were significantly reduced (P<0.05, P<0.01), and the Bcl-2 protein level in the AE low concentration group was significantly increased (P<0.01). ConclusionThe results of this experiment show that EEBM-treated ADSCs or ADSCs may delay aging in castrated rats by inhibiting cell apoptosis, reducing cell cycle inhibitors and pro-inflammatory factors, enhancing antioxidant capacity, and reducing oxidative reactions. Moreover, EEBM-treated ADSCs demonstrate stronger anti-aging effects than ADSCs alone. This study provides experimental evidence supporting the clinical use of EEBM to intervene in ADSCs and delay aging.

AIM: To explore the control effects of wearing orthokeratology lens for 1 a on adolescent myopia patients with different diopters.METHODS: Prospective non-randomized controlled study. A total of 120 adolescent myopic patients(224 eyes), with an average age of 11.00±2.08 years old, who were fitted with orthokeratology lenses in the optometry department of our hospital from November 2022 to May 2023 were collected. There were 3 groups according to the spherical equivalent, including 86 eyes in the group of -0.50--2.00 D, 99 eyes in the group -2.25--4.00 D, and 39 eyes in group -4.25--6.00 D. Patients were followed up for 1 a to observe the changes of uncorrected visual acuity, axial length, corneal curvature, corneal central thickness and corneal endothelial cells density in the three groups after wearing lens for 1 a.RESULTS:A total of 113 cases(212 eyes)were followed up for 1 a, including 82 eyes in the group of -0.50--2.00 D, 95 eyes in the group of -2.25--4.00 D, and 35 eyes in the group of -4.25--6.00 D. There was no statistical difference in corneal central thickness and corneal endothelial cell density among the three groups of patients after wearing lens for 1 a(all P>0.05). Uncorrected visual acuity was significantly improved, and flat kerotometry(FK)and steep kerotometry(SK)were significantly flatter(both P<0.01). Furthermore, the growth of axial length in the three groups of patients after wearing lens for 1 a was 0.21±0.26, 0.13±0.21 and 0.09±0.10 mm, respectively(P<0.05). There were differences between the -0.50--2.00 D group and the -2.25--4.00 D group and -4.25--6.00 D group(P=0.028, 0.010), and there were no differences between the -2.25--4.00 D group and the -4.25--6.00 D group(P=0.344).CONCLUSION:It is safe and effective for young myopia patients to wear orthokeratology lenses, which can prevent the non-benign growth of the axial length and effectively delay the development of myopia, and the myopia control effect is better especially for myopia patients of above -2.0 D.

OBJECTIVE To investigate the improvement effect and potential mechanism of Qingxue xiaozhi jiangtang formula on insulin resistance (IR) in type 2 diabetes mellitus (T2DM) rats. METHODS T2DM rat model was established by intraperitoneal injection of 30 mg/kg streptozotocin combined with high-fat and high-sugar diet. The rats were randomly divided into normal control group, model group, Qingxue xiaozhi jiangtang formula low-dose and high-dose groups (6.525, 13.05 g/kg, calculated by raw material) and metformin group (positive control, 0.18 g/kg), with 8 rats in each group. Administration groups were given relevant medicine intragastrically; normal control group and model group were given constant volume of normal saline intragastrically, once a day, for consecutive 6 weeks. Body mass and fasting blood glucose (FBG) were determined, and oral glucose tolerance test was conducted. Serum fasting insulin (FINS) level was measured to calculate the insulin resistance index (HOMA-IR) and insulin sensitivity index (ISI). Additionally, the level of serum lipids, liver function, oxidative stress indicators and inflammatory factors were assessed. The phosphorylation levels of kinase R-like endoplasmic reticulum kinase (PERK) and forkhead box O1 (FOXO1) protein in liver tissue of rats were determined. RESULTS Compared with model group, the body weight, ISI, the levels of high-density lipoprotein cholesterol and superoxide dismutase were increased significantly in Qingxue xiaozhi jiangtang formula high-dose group and metformin group (P<0.05); FBG, blood glucose level at 120 minutes of glucose loading, area under the curve of glucose, FINS, HOMA-IR, low-density lipoprotein cholesterol, total cholesterol, triglyceride, alanine transaminase, aspartate transaminase, alkaline phosphatase, malondialdehyde, interleukin-6, tumor necrosis factor-α, and C-reactive protein levels were significantly reduced (P< Δ0.05); the pathological damage of liver tissue had significantlyimproved, and the phosphorylation levels of PERK and FOXO1 proteins in liver tissue were significantly decreased (P<0.05). CONCLUSIONS Qingxue xiaozhi jiangtang formula can regulate glucose and lipid metabolism, inflammation factor and oxidative stress levels, and alleviate insulin resistance in T2DM rats. Its mechanism of action may be related to the inhibition of the PERK/FOXO1 signaling pathway.
