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.

Atopic dermatitis （AD） is a common pruritic and chronic inflammatory dermatosis in clinical practice and is one of the diseases responding specifically to traditional Chinese medicine （TCM）. With the launch of biological agents and small molecule drugs and the development and implementation of guidelines of diagnosis and treatment， clinical pathways of treatment of moderate to severe AD， and consensus on the whole-process management of AD， the clinical efficacy of moderate to severe AD has been significantly improved. However， there are still many unmet clinical needs that require more effective methods to meet. In response to the Opinions of the CPC Central Committee and the State Council on Facilitating the Inheritance， Innovation， and Development of Traditional Chinese Medicine and the spirit of the National Conference on TCM， the China Association of Chinese Medicine organized more than 20 experts in TCM dermatology， Western medicine dermatology， interdisciplinary fields， and industries to discuss the difficulties and advantages of TCM in the treatment of AD. TCM treatment for AD can not only improve rash and relieve itching but also solve many concomitant syndromes. The abundant external treatment methods of TCM have advantages for different special populations and rash characteristics. The concept of treating disease before its onset in TCM is in line with the chronic disease management mode of prevention and treatment of atopic march and prevention of recurrence. In addition， TCM therapy can reduce the use of topical glucocorticoids and has good safety. Regarding the comorbidity of AD， equal emphasis on TCM and Western medicine and multidisciplinary joint treatment should be advocated to achieve maximum benefit for patients. The exchange of TCM and Western medicine has clarified the positioning and advantages of TCM intervention in AD， providing guidance for clinical and scientific research.

A 71-year-old male presented with esophageal cancer and severe aortic valve regurgitation. Treatment strategies for such patients are controversial. Considering the risks of cardiopulmonary bypass and potential esophageal cancer metastasis, we successfully performed transcatheter aortic valve implantation and minimally invasive three-incision thoracolaparoscopy combined with radical resection of esophageal cancer (McKeown) simultaneously in the elderly patient who did not require neoadjuvant treatment. This dual minimally invasive procedure took 6 hours and the patient recovered smoothly without any surgical complications.

ObjectiveTo investigate the changing trend of hemoglobin （Hb） and related influencing factors in patients with liver failure after artificial liver support system （ALSS） therapy. MethodsA total of 106 patients with liver failure who were hospitalized and received ALSS therapy in our hospital from January to December 2018 were enrolled and analyzed in terms of clinical data and red blood cell parameters such as Hb， mean corpuscular volume （MCV）， mean corpuscular hemoglobin （MCH）， mean corpuscular hemoglobin concentration （MCHC）， and red blood cell distribution width-coefficient of variation （RDW-CV）. A one-way repeated-measures analysis of variance was used for comparison of continuous data with repeated measurement between groups， and the paired t-test was used for comparison between two groups. The Kruskal-Wallis H test was used for comparison of continuous data with skewed distribution between multiple groups， the Mann-Whitney U test was used for further comparison between two groups. Univariate and multivariate linear regression analyses were used to identify the influencing factors for the reduction in Hb after ALSS therapy. ResultsThe 106 patients with liver failure received 606 sessions of ALSS therapy， and Hb was measured for 402 sessions before and after treatment. There was a significant reduction in Hb after ALSS therapy in the patients with liver failure （97.49±20.51 g/L vs 109.38±20.22 g/L， t=32.764， P<0.001）. Longitudinal observation was further performed for 14 patients with liver failure， and the results showed that the level of Hb was 108.50±21.61 g/L before the last session of ALSS therapy， with certain recovery compared with the level of Hb （103.14±19.15 g/L） on the second day after ALSS， and there was an increase in Hb on day 3 （102.57±21.73 g/L） and day 7 （105.57±22.04 g/L） after surgery. The level of Hb in patients with liver failure on the second day after ALSS decreased with the increase in the number of ALSS sessions （F=8.996， P<0.001）， while MCV and MCH gradually increased with the increase in the number of ALSS sessions （F=9.154 and 13.460， P=0.004 and P<0.001）， and RDW-CV first gradually increased and then gradually decreased （F=4.520， P=0.032）； MCHC showed fluctuations with no clear trend （F=0.811， P=0.494）. The multivariate linear regression analysis showed that the duration of ALSS therapy， the mode of ALSS therapy， and initial treatment were independent risk factors for the reduction in Hb after ALSS therapy. ConclusionALSS therapy can influence the level of peripheral blood Hb in patients with liver failure， and patient blood management should be strengthened for patients with liver failure who are receiving ALSS therapy.

The occurrence of diabetes mellitus （DM） is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver，fat，skeletal muscle，islets， and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response，improving insulin resistance，and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing，heat-clearing， and detoxicating medicinal，which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore，by summarizing the mechanisms between macrophage activation，polarization， and insulin resistance in various tissues，this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio，providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

Objective: To investigate the mechanism of action of Prim-O-glucosylcimifugin (POG) to improve cholesterol metabolism in osteoarthritic (OA) chondrocytes based on the long noncoding RNA nuclear-enriched transcript 1 (lncRNA NEAT1)/microRNA-128-3p (miR-128-3p) pathway. Methods: For in vivo experiments, 60 mice were divided into the normal, sham operation, model, and POG groups using the random number table method, with 15 mice per group. The osteoarthritis mouse model was constructed using the modified Hulth method in the model and POG groups. Mice in the POG group were administered 30 mg/(kg·d)POG by gavage. The other groups were administered an equal amount of normal saline for 8 weeks. The cartilage tissue structure of mice in each group was observed using hematoxylin and eosin staining. Real-time PCR was used to detect changes in the lncRNA NEAT1 and miR-128-3p mRNA expression levels in the cartilage tissues of mice. Western blotting was used to detect the protein expressions of ATP-binding cassette transporter A1 (ABCA1), liver X receptor β (LXRβ), matrix metalloprotein-3 (MMP-3), and B-lymphoblastoma-2-associated X protein (Bax) in articular cartilage of mice. An enzyme-linked immunosorbent assay was used to measure the tumor necrosis factor-α (TNF-α) content in the synovial fluid of mice. A biochemical microplate assay was used to measure the total cholesterol level in the synovial fluid of mice. The in vitro experiments were divided into the negative control, interleukin-1β(IL-1β), IL-1β+ POG, IL-1β+ oe-lncRNA NEAT1, IL-1β+ oe-lncRNA NEAT1 + POG, IL-1β + miR-128-3p inhibition, and IL-1β+ miR-128-3p inhibition+ POG groups. An OA model was established by inducing chondrocytes with IL-1β for 24 h, and 90 mg/L of POG and miR-128-3p inhibitor(50 nmol/L) were administered for 48 h as an intervention. lncRNA NEAT1 expression in chondrocytes was detected using fluorescence in situ hybridization. A dual luciferase assay was used to detect the targeting relationship between lncRNA NEAT1 and miR-128-3p. Lentiviral plasmids overexpressing lncRNA NEAT1 were used to transfect mouse chondrocytes. Real-time PCR was used to detect the effect of lncRNA NEAT1 overexpression on the mRNA level of miR-128-3p in chondrocytes. Western blotting was used to detect ABCA1, LXRβ, MMP-3, and Bax protein expression in chondrocytes after lncRNA NEAT1 overexpression and miR-128-3p inhibition. Results: POG significantly reduced OA cartilage tissue damage. Compared with the model group, the lncRNA NEAT1 mRNA level decreased, whereas the miR-128-3p mRNA level increased in the cartilage tissue of the POG group (P<0.05). Compared with the model group, ABCA1 and LXRβ protein expression increased in the POG group, whereas MMP-3 and Bax protein expression decreased (P<0.05). The TNF-α levels decreased in the POG group compared to the model group (P<0.05). Compared with the model group, the total cholesterol level in the synovial fluid of the joint of mice in the POG group decreased (P<0.05). The mean fluorescence intensity of lncRNA NEAT1 in the IL-1β+ POG group decreased compared with the IL-1β group (P<0.05). The relative luciferase activity in the miR-128-3p mimics group bound to the lncRNA NEAT1-WT plasmid decreased compared with the miR-128-3p negative control group (P<0.05). The lncRNA NEAT1 mRNA levels decreased, whereas the miR-128-3p mRNA levels increased in the IL-1β+ oe-lncRNA NEAT1 + POG group compared with the IL-1β+ oe-lncRNA NEAT1 group (P<0.05). Compared with the IL-1β+ POG group, ABCA1 and LXRβ protein expression decreased, whereas MMP-3 and Bax protein expression increased (P<0.05). Conclusion POG mediates lncRNA NEAT1/miR-128-3p to improve cholesterol metabolism in OA chondrocytes.

Alzheimer’s disease (AD) is a central neurodegenerative disease characterized by progressive cognitive decline and memory impairment in clinical. Currently, there are no effective treatments for AD. In recent years, a variety of therapeutic approaches from different perspectives have been explored to treat AD. Although the drug therapies targeted at the clearance of amyloid β-protein (Aβ) had made a breakthrough in clinical trials, there were associated with adverse events. Neuroinflammation plays a crucial role in the onset and progression of AD. Continuous neuroinflammatory was considered to be the third major pathological feature of AD, which could promote the formation of extracellular amyloid plaques and intracellular neurofibrillary tangles. At the same time, these toxic substances could accelerate the development of neuroinflammation, form a vicious cycle, and exacerbate disease progression. Reducing neuroinflammation could break the feedback loop pattern between neuroinflammation, Aβ plaque deposition and Tau tangles, which might be an effective therapeutic strategy for treating AD. Traditional Chinese herbs such as Polygonum multiflorum and Curcuma were utilized in the treatment of AD due to their ability to mitigate neuroinflammation. Non-steroidal anti-inflammatory drugs such as ibuprofen and indomethacin had been shown to reduce the level of inflammasomes in the body, and taking these drugs was associated with a low incidence of AD. Biosynthetic nanomaterials loaded with oxytocin were demonstrated to have the capability to anti-inflammatory and penetrate the blood-brain barrier effectively, and they played an anti-inflammatory role via sustained-releasing oxytocin in the brain. Transplantation of mesenchymal stem cells could reduce neuroinflammation and inhibit the activation of microglia. The secretion of mesenchymal stem cells could not only improve neuroinflammation, but also exert a multi-target comprehensive therapeutic effect, making it potentially more suitable for the treatment of AD. Enhancing the level of TREM2 in microglial cells using gene editing technologies, or application of TREM2 antibodies such as Ab-T1, hT2AB could improve microglial cell function and reduce the level of neuroinflammation, which might be a potential treatment for AD. Probiotic therapy, fecal flora transplantation, antibiotic therapy, and dietary intervention could reshape the composition of the gut microbiota and alleviate neuroinflammation through the gut-brain axis. However, the drugs of sodium oligomannose remain controversial. Both exercise intervention and electromagnetic intervention had the potential to attenuate neuroinflammation, thereby delaying AD process. This article focuses on the role of drug therapy, gene therapy, stem cell therapy, gut microbiota therapy, exercise intervention, and brain stimulation in improving neuroinflammation in recent years, aiming to provide a novel insight for the treatment of AD by intervening neuroinflammation in the future.

ObjectiveTo investigate the role of paraventricular nucleus (PVN) corticotropin releasing hormone (CRH) neurons in chronic restraint stress (CRS)-induced anxiety-like behavior. And whether exercise relieves chronic restraint stress-induced anxiety through PVN CRH neurons. MethodsTwenty 8-week-old male C57BL/6J mice were randomly divided into control (Ctrl) group and chronic restraint stress (CRS) group. The open field test (OFT) and elevated plus maze (EPM) were used to evaluate anxiety-like behavior of the mice. Food intake was recorded after CRS. Immunofluorescence staining was used to label the expression of c-Fos expression in PVN and calculate the co-expression of c-Fos and CRH neurons. We used chemogenetic activation of PVN CRH neurons to observed the anxiety-like behavior. 8-week treadmill training (10-16 m/min, 60 min/d, 6 d/week) were used to explore the role of exercise in ameliorating CRS-induced anxiety behavior and how PVN CRH neurons involved in it. ResultsCompared with Ctrl group, CRS group exhibited significant anxiety-like behavior. In OFT, the mice in CRS groups spent less time in center area (P<0.001). In EPM, the time in open arm in CRS group were significantly decreased (P<0.001). Besides, food intake was also suppressed in CRS group compared with Ctrl group (P<0.05). Compared with Ctrl group, CRS significantly increase c-Fos expression in PVN and most of CRH neurons co-express c-Fos (P<0.001). Chemogenetic activation of PVN CRH neurons induced anxiety-like behavior (P<0.05) and inhibited feeding behavior (P<0.01). Exercise relieves chronic restraint stress-induced anxiety (P<0.001) and relieved the anorexia caused by chronic restraint stress (P<0.05). Aerobic exercise inhibited the CRS labeled c-Fos in PVN CRH neurons (P<0.001). Furthermore, ablation of PVN CRH neurons attenuated CRS induced anxiety-like behavior. ConclusionCRS activated PVN CRH neurons, induced anxiety-like behavior and reduced food intake. 8-week exercise attenuated CRS-induced anxiety-like behavior through inhibiting PVN CRH neuron. Ablation of CRH PVN neurons ameliorated CRS-induced anxiety-like behavior. These finding reveals a potential neural mechanism of exercise-relieving CRS-induced anxiety-like behavior. This provides a new idea and theoretical basis for the treatment of anxiety and related mental disorders.

OBJECTIVE To investigate the current status of quality management of cold chain medicines in direct-to-patient （DTP） pharmacies and propose measures for pre-emptive risk management， providing references for the quality risk management of cold chain medicines. METHODS Based on the requirements of national regulations， a survey was conducted on the quality management of cold chain medicines in DTP pharmacies of J Province from November 2023 to February 2024， focusing on the receipt， storage， distribution， and delivery processes， using questionnaires， telephone interviews， and on-site visits. Common quality management issues in the operation of cold chain medicines were identified， and the causes of these issues were analyzed to propose feasible pre-emptive risk management measures. RESULTS & CONCLUSIONS A total of 122 DTP pharmacies participated in the questionnaire survey， and personnel from 30 DTP pharmacies participated in on-site and telephone interviews. Typical problems were identified in some DTP pharmacies， including insufficient personnel allocation or training， incomplete or inadequate implementation of quality system documentation， inadequate provision or management of cold chain facilities and equipment， and non-compliant storage and distribution of cold chain medicines. These issues posed certain risks to the quality management of cold chain medicines. It is recommended that DTP pharmacies strengthen personnel allocation and training， improve quality system documentation， enhance the provision and management of facilities and equipment， standardize storage and transportation operations， and strengthen supervision and assessment as pre-emptive measures. In addition， all sectors of society should also collaborate in governance from the perspective of ensuring the safety of cold chain drug storage and transportation， in order to mitigate the risk of quality and safety issues during the distribution of cold chain drugs and guarantee the safe and effective use of medications for patients.
