Objective To evaluate the safety and efficacy of a self-developed micro-normothermic machine perfusion (NMP) system (micro-perfusion device) for preserving isolated porcine limbs. Methods Five healthy Landrace pigs were selected, and their left and right forelimbs were randomly divided into the NMP group and static cold storage (SCS) group. The NMP group was perfused with the self-developed micro-perfusion device and polymerized hemoglobin perfusate for 32 hours at normothermia, while the SCS group was preserved at 4 ℃. Hemodynamic parameters such as perfusion pressure and flow were monitored. The pH value, partial pressure of oxygen (PO2), lactic acid (Lac), creatine kinase (CK) and lactate dehydrogenase (LDH) in the perfusate were measured. Hematoxylin-eosin staining was used to assess the muscle tissue structure, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling was employed to evaluate muscle cell apoptosis, and immunohistochemistry staining was applied to detect the expressions of tumor necrosis factor (TNF)-α and interleukin (IL)-6. A mixed-effects model was used to analyze the effects of time and treatment methods on tissue structure, cell apoptosis and inflammatory factors. Results The device could stably maintain a perfusion pressure of (69±15) mmHg and a flow rate of (117±42) mL/min. The pH value and electrolytes of the perfusate were generally stable, with PO2 maintained at a high level. Lac was maintained at 5.38(3.81, 6.45) mmol/L, while CK and LDH increased over time. After 32 hours of perfusion in the NMP group, both the myocyte spacing and apoptosis rate were better than those in the SCS group. Mixed-effects model analysis showed that there were statistically significant differences in the effects of NMP treatment and SCS treatment on myocyte spacing and apoptosis rate per unit time (both P < 0.05). There were no statistically significant differences in TNF-α and IL-6 between the two groups, and mixed-effects model analysis showed no statistically significant differences in the effects of NMP treatment and SCS treatment on TNF-α and IL-6 per unit time (both P > 0.05). Conclusions The micro-perfusion device used in this study may achieve 32-hour normothermic preservation in a porcine limb amputation model, maintain basic metabolism and ionic homeostasis, reduce muscle structural damage and cell apoptosis without inducing additional inflammatory responses. This technology is expected to significantly extend the time window for replantation of amputated limbs in disaster rescue and long-distance transportation, providing an important technical basis for clinical translation and subsequent replantation research.

ObjectiveTo systematically quantify the multidimensional effect of virtual reality-based exergaming (VREG) on health outcomes among individuals with cognitive impairment under the framework of the International Classification of Functioning, Disability and Health (ICF). MethodsMeta-analysis was conducted in accordance with the PRISMA statement. PubMed, Cochrane Library, Embase, Scopus, Web of Science, CNKI, Wanfang Data and VIP were researched for randomized controlled trials (RCTs) investigating VREG for cognitive impairment, with the search deadline set on February 1, 2026. The Cochrane Risk of Bias 2.0 tool was adopted to evaluate the methodological quality of included studies. A three-level meta-analytic model was implemented with R 4.4.2. The GRADE framework was further used to rate the certainty of pooled evidence. ResultsA total of 22 RCTs were included. VREG might improve global cognitive function (SMD = 0.69, 95%CI 0.11 to 1.28, P = 0.022), memory (SMD = 0.47, 95%CI 0.07 to 0.87, P = 0.023), attention (SMD = 0.62, 95%CI 0.23 to 1.01, P = 0.004), executive function (SMD = 0.42, 95%CI 0.09 to 0.75, P = 0.013), balance (SMD = 0.54, 95%CI 0.07 to 1.00, P = 0.027), muscle strength (SMD = 0.63, 95%CI 0.37 to 0.88, P = 0.001), mobility (SMD = 0.29, 95%CI 0.04 to 0.54, P = 0.024) and quality of life (SMD = 0.29, 95%CI 0.03 to 0.56, P = 0.029). No significant effect was observed for depressive symptoms, comprehensive physical fitness and fall risk (all P > 0.05). Subgroup and meta-regression analyses indicated that session duration < 45 minutes produced the largest improvement in attention (SMD = 0.95, 95%CI 0.55 to 1.34, P < 0.001); intervention cycles of twelve to 24 weeks were optimal for mobility (SMD = 0.85, 95%CI 0.44 to 1.25, P < 0.001); age negatively correlated to balance improvement (β = -0.11, 95%CI -0.20 to -0.02, P = 0.020), suggesting less intervention benefits among older participants. ConclusionVREG is an effective non-pharmacological intervention to improve multidimensional physical and mental health in people with cognitive impairment. Protocols featuring short single sessions with long-term duration should be prioritized.

ObjectiveTo observe the clinical efficacy and safety of Zhuyuwan in the treatment of hyperlipidemia. MethodsIn this study, hyperlipidemia patients treated in the Hospital of Chengdu University of Traditional Chinese Medicine (TCM) from September 2022 to December 2023 were randomly assigned into a control group and an observation group. Finally, 162 valid cases were included, encompassing 74 cases in the control group and 88 cases in the observation group. The control group was treated with atorvastatin calcium tablets, and the observation group with atorvastatin calcium tablets + Zhuyuwan extract granules. Both groups were treated for 8 weeks. The efficacy in terms of blood lipid level recovery, blood lipid levels, TCM syndrome distribution, efficacy in terms of TCM syndrome, and TCM symptom scores were compared between the two groups as well as between before and after treatment. Liver and kidney functions were monitored for safety assessment. ResultsIn terms of blood lipid level recovery, the total response rate in the observation group was 86.36% (76/88) and that in the control group was 86.49% (64/74), with no statistically significant difference between the two groups. After treatment, both groups showed declines in levels of triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C) (P<0.05) and elevations in the level of high-density lipoprotein cholesterol (HDL-C) (P<0.05). Moreover, the observation group outperformed the control group in recovering the levels of TG, LDL-C, and HDL-C (P<0.05, P<0.01). In terms of TCM syndrome, hyperlipidemia was mostly caused by phlegm turbidity and obstruction. The total response rate in terms of TCM syndrome in the observation group was 87.30% (55/63), which was higher than that (63.46%, 33/52) in the control group (χ2=9.102, P<0.01). After treatment, the scores of total TCM symptoms, primary symptoms, and secondary symptoms decreased in both groups (P<0.05), and the observation group had lower scores than the control group (P<0.01). The observation group was superior to the control group in alleviating obesity, chest tightness, and low food intake (P<0.05). In terms of safety, the level of aminotransferase was slightly elevated in the control group, and no obvious adverse reaction was observed in the observation group, with no statistical significance in the incidence of adverse reactions. ConclusionZhuyuwan combined with atorvastatin can not only recover blood lipid levels and alleviate TCM symptoms but also reduce the occurrence of adverse reactions.

ObjectiveTo explore the pharmacological mechanism involved in the treatment of allergic cough (AC) by Xiaoer Huatan Zhike granules (XEHT) based on proteomics and network pharmacology. MethodsAfter sensitization by intraperitoneal injection of 1 mL suspension containing 2 mg ovalbumin (OVA) and 100 mg aluminum hydroxide, a guinea pig model of allergic cough was constructed by nebulization with 1% OVA. The modeled guinea pigs were randomized into the model, low-, medium- and high-dose (1, 5, 20 g·kg-1, respectively) XEHT, and sodium montelukast (1 mg·kg-1) groups (n=6), and another 6 guinea pigs were selected as the blank group. The guinea pigs in drug administration groups were administrated with the corresponding drugs by gavage, and those in the blank and model groups received the same volume of normal saline by gavage, 1 time·d-1. After 10 consecutive days of drug administration, the guinea pigs were stimulated by 1% OVA nebulization, and the coughs were observed. The pathological changes in the lung tissue were observed by hematoxylin-eosin staining. The enzyme-linked immunosorbent assay was performed to measure the levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD), and malondialdehyde (MDA) in the bronchoalveolar lavage fluid (BALF) and immunoglobulin G (IgG) and immunoglobulin A (IgA) in the serum. Immunohistochemistry (IHC) was employed to observe the expression of IL-6 and TNF-α in the lung tissue. Transmission electron microscopy was employed observe the alveolar type Ⅱ epithelial cell ultrastructure. Real-time PCR was employed to determine the mRNA levels of IL-6, interleukin-1β (IL-1β), and TNF-α in the lung tissue. Label-free proteomics was used to detect the differential proteins among groups. Network pharmacology was used to predict the targets of XEHT in treating AC. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was performed to search for the same pathways from the results of proteomics and network pharmacology. ResultsCompared with the blank group, the model group showed increased coughs (P<0.01), elevated levels of CRP, TNF-α, IL-6, and MDA and lowered level of SOD in the BALF (P<0.05, P<0.01), elevated levels of IgA and IgG in the serum (P<0.05, P<0.01), congestion of the lung tissue and infiltration of inflammatory cells, increased expression of IL-6 and TNF-α (P<0.01), large areas of low electron density edema in type Ⅱ epithelial cells, obvious swelling and vacuolization of the organelles, karyopyknosis or sparse and dissolved chromatin, and up-regulated mRNA levels of IL-6, IL-1β, and TNF-α (P<0.01). Compared with the model group, the drug administration groups showed reduced coughs (P<0.01), lowered levels of CRP, TNF-α, IL-6, and MDA and elevated level of SOD in the BALF (P<0.05, P<0.01), alleviated lung tissue congestion, inflammatory cell infiltration, and type Ⅱ epithelial cell injury, and decreased expression of IL-6 and TNF-α (P<0.01). In addition, the medium-dose XEHT group and the montelukast sodium group showcased lowered serum levels of IgA and IgG (P<0.05, P<0.01). The medium- and high-dose XEHT groups and the montelukast sodium showed down-regulated mRNA levels of IL-6, IL-1β, and TNF-α and the low-dose XEHT group showed down-regulated mRNA levels of IL-6 and TNF-α (P<0.05, P<0.01). Phospholipase D, mammalian target of rapamycin (mTOR), and epidermal growth factor receptor family of receptor tyrosine kinase (ErbB) signaling pathways were the common pathways predicted by both proteomics and network pharmacology. ConclusionProteomics combined with network pharmacology reveal that XEHT can ameliorate AC by regulating the phospholipase D, mTOR, and ErbB signaling pathways.
