ObjectiveBased on traditional quality evaluation of Gardeniae Fructus（GF） recorded in historical materia medica， this study systematically compared the quality differences between wild and cultivated GF from morphological characteristics， microscopic features， and contents of primary and secondary metabolites. MethodsVernier calipers and analytical balances were used to measure the length， diameter and individual fruit weight of wild and cultivated GF， and the aspect ratio was calculated. A colorimeter was used to determine the chromaticity value of wild and cultivated GF， and the paraffin sections of them were prepared by safranin-fast green staining and examined under an optical microscope to observe their microstructure. Subsequently， the contents of water-soluble and alcohol-soluble extracts of wild and cultivated GF were detected by hot immersion method under the general rule 2201 in volume Ⅳ of the 2020 edition of the Pharmacopoeia of the People's Republic of China， the starch content was measured by anthrone colorimetric method， the content of total polysaccharides was determined by phenol-sulfuric acid colorimetric method， the sucrose content was determined by high performance liquid chromatography coupled with evaporative light scattering detection（HPLC-ELSD）， and the contents of representative components in them were measured by ultra-performance liquid chromatography（UPLC）. Finally， correlation analysis was conducted between quality traits and phenotypic traits， combined with multivariate statistical analysis methods such as principal component analysis（PCA） and orthogonal partial least squares-discriminant analysis（OPLS-DA）， key differential components between wild and cultivated GF were screened. ResultsIn terms of traits， the wild GF fruits were smaller， exhibiting reddish yellow or brownish red hues with significant variation between batches. While the cultivated GF fruits are larger， displaying deeper orange-red or brownish red. The diameter and individual fruit weight of cultivated GF were significantly greater than those of wild GF， while the blue-yellow value（b^*） of wild GF was significantly higher than that of cultivated GF. In the microstructure， the mesocarp of wild GF contained numerous scattered calcium oxalate cluster crystals， while the endocarp contained stone cell class round， polygonal or tangential prolongation， undeveloped seeds were visible within the fruit. In contrast， the mesocarp of cultivated GF contained few calcium oxalate cluster crystals， or some batches exhibited extremely numerous cluster crystals. The stone cells in the endocarp were predominantly round-like， with the innermost layer arranged in a grid pattern. Seeds were basically mature， and only a few immature seeds existed in some batches. Regarding primary metabolite content， wild GF exhibited significantly higher total polysaccharide level than cultivated GF（P<0.01）. In category-specific component content， wild GF exhibited significantly higher levels of total flavonoids and total polyphenols compared to cultivated GF（P<0.01）. Analysis of 12 secondary metabolites revealed that wild GF exhibited significantly higher levels of Shanzhiside， deacetyl asperulosidic acid methyl ester， gardenoside and chlorogenic acid compared to cultivated GF（P<0.01）. Conversely， the contents of genipin 1-gentiobioside， geniposide and genipin were significantly lower in wild GF（P<0.01）. ConclusionThere are significant differences between wild and cultivated GF in terms of traits， microstructure， and contents of primary and secondary metabolites. At present， the quality evaluation system of cultivated GF remains incomplete， and this study provides a reference for guiding the production of high-quality GF medicinal materials.

Objective To preliminarily investigate the safety and efficacy of donor pancreas needle biopsy in simultaneous pancreas-kidney transplantation. Methods Clinical data of 7 cases undergoing donor pancreas biopsy were collected retrospectively. All cases underwent donor pancreas biopsy before or during simultaneous pancreas-kidney transplantation. Frozen section or paraffin sectioning techniques were used for tissue preparation, and hematoxylin-eosin and Masson staining were performed to histologically evaluate the donor pancreas. The quality of donor pancreas was comprehensively assessed by combining histological findings with the donor's clinical data. Postoperative follow-up data of 5 simultaneous pancreas-kidney transplant recipients were collected to summarize the safety of donor pancreas biopsy and the prognosis of transplant recipients. Results The 7 pancreas donors were aged 28 to 62 years, with a body mass index ranging from 20.76 to 27.68 kg/m². Liver ultrasound indicated fatty liver in 3 cases, while pancreatic ultrasound did not reveal any significant abnormalities. Among them, biopsy was performed on 2 donors after completion of pancreatic procurement and processing, and the frozen section histology showed moderate acute pancreatitis changes (edema of acinar cells, necrosis and inflammatory cell infiltration). Combined with a serum amylase level elevated more than 3 times the upper limit of normal value, these two donor pancreases were finally discarded. The remaining 5 cases underwent biopsy immediately after pancreatic vascular anastomosis during simultaneous pancreas-kidney transplantation, and histological evaluation was performed on paraffin-embedded sections. No biopsy-related complications (such as bleeding, pancreatic fistula, etc.) occurred after transplantation. One recipient died of severe infection 2 months after transplantation, while the other 4 recipients were followed up for more than 5 years, with well-functioning transplant kidneys and pancreases. Conclusions Donor pancreas biopsy is relatively safe, and the risk of biopsy-related complications after transplantation is controllable. Comprehensive assessment of donor pancreas quality by combining histological evaluation with the donor's clinical indicators is conducive to improving the accuracy of donor pancreas selection and organ utilization.

Cold ischemia-reperfusion injury (CIRI) is a major contributor to delayed graft function and long-term graft failure after kidney transplantation.Its pathogenesis involves multiple mechanisms, including energy metabolism disorders, oxidative stress and sterile inflammatory responses.Increasing evidence indicates that immune cells play a central regulatory role in the initiation and progression of CIRI.Damage-associated molecular patterns released during cold ischemia and reperfusion activate innate immunity, leading to the rapid recruitment of neutrophils, macrophages, dendritic cells and amplification of inflammatory cascades.Subsequently, adaptive immune cells, including T cells and B cells, are activated and further contribute to sustained inflammation, disruption of immune tolerance and graft injury.Through cytokine signaling, chemokine-mediated recruitment and antigen presentation, different immune cell subsets form a complex interactive network that ultimately determines the severity and outcome of CIRI.This review summarizes the roles and mechanisms of innate and adaptive immune cells in renal allograft CIRI, highlights their interconnections, and discusses emerging immune cell-targeted therapeutic strategies, aiming to provide a theoretical basis for improving clinical outcomes in kidney transplantation.

Objective To investigate the expression of calumenin(CALU)in gastric cancer and its effect on metastasis and invasion of gastric cancer,and analyze its relationship with the prognosis of gastric cancer patients.Methods The Cancer Genome Atlas(TCGA)database was used to analyze the expression level of CALU in gastric cancer and its impact on patient prognosis.A total of 102 pairs of gastric cancer and paracancerous tissue samples were collected from 189 gastric cancer patients who underwent partial gastrectomy in First Affiliated Hospital of Army Medical University from January 2018 to December 2022.The expression of CALU in gastric cancer and paracancerous tissues was detected by immunohistochemical assay,and the relationship of its expression with clinicopathological parameters was statistically analyzed.After gastric cancer cells with CALU knockdown and overexpression were constructed,and the efficiencies of knockdown and overexpression were evaluated by Western blotting as well as RT-qPCR.Transwell assay was applied to determine the effect of CALU on the migration and invasion abilities of gastric cancer cells.Results Bioinformation analysis found that CALU was significantly highly expressed in gastric cancer tissues(P<0.05),and its expression level was negatively correlated with the prognosis of patients(P<0.05).Immunohistochemical results showed that the expression level of CALU was obviously highly in gastric cancer tissues than the paracancerous tissues(P<0.01),and its level was positively correlated with the depth of infiltration(P<0.01),lymph node metastasis(P<0.01),and TNM stage(P<0.05).Statistical analysis revealed that the clinical data of 102 patients showed that CALU expression was positively correlated with the TNM stage(P=0.021)and T stage(P<0.001)and N stage(P=0.028).CALU knockdown significantly inhibited the migration and invasion abilities of gastric cancer cells(P<0.01),while over-expression obtained the opposite results.Conclusion CALU is highly expressed in gastric cancer tissues and promotes metastasis and invasion of gastric cancer and thus leads to poor prognosis in patients.

OBJECTIVES: To explore the active components that mediate the therapeutic effect of Centella asiatica on psoriasis and their therapeutic mechanisms. METHODS: TCMSP, TCMIP, PharmMapper, Swiss Target Prediction, GeneCards, OMIM and TTD databases were searched for the compounds in Centella asiatica and their targets and the disease targets of psoriasis. A drug-active component-target network and the protein-protein interaction network were constructed, and DAVID database was used for pathway enrichment analysis. In a RAW264.7 macrophage model of LPS-induced inflammation, the anti-inflammatory effect of 7.5, 15, 30, and 60 μmol/L quercetin, asiaticoside, and asiatic acid, which were identified as the main active components in Centella asiatica, were tested by measuring cellular production of NO, TNF‑α and IL-6 using Griess method and ELISA and by detecting mRNA expressions of IL-23, IL-17A, TNF-α and IL-6 and protein expressions of p-STAT3 (Tyr705) and p-STAT3 (Ser727) with RT-qPCR and Western blotting. RESULTS: A total of 139 targets of Centella asiatica and 4604 targets of psoriasis were obtained, and among them CASP3, EGFR, PTGS2, and ESR1 were identified as the core targets. KEGG analysis suggested that quercetin, asiaticoside, and asiatic acid in Centella asiatica were involved in cancer and IL-17 and MAPK signaling pathways. In the RAW264.7 macrophage model of inflammation, treatment with quercetin significantly reduced cellular production of NO, TNF‑α and IL-6, and lowered mRNA expressions of IL-23, IL-17A, TNF‑α and IL-6 and protein expressions of p-STAT3 (Tyr705) and p-STAT3 (Ser727). CONCLUSIONS Quercetin, asiaticoside and asiatic acid are the main active components in Centella asiatica to mediate the therapeutic effect against psoriasis, and quercetin in particular is capable of suppressing cellular production of NO, TNF‑α and IL-6 and regulating the IL-23/IL-17A inflammatory axis by mediating STAT3 phosphorylation to inhibit inflammatory response.

Aging is an inevitable, physiological process of the human body, leading to deterioration in bodily function and increased susceptibility to various diseases. Effective endogenous therapeutic strategies for anti-aging and related diseases remain limited. Exercise confers multifaceted benefits to physical health by augmenting osteogenic and myogenic processes, enhancing cardiovascular and nervous system function, and attenuating chronic inflammation. Angiogenesis and lymphangiogenesis play pivotal roles in anti-aging, tissue repair, and immune response modulation, underscoring their potential as therapeutic targets for age-related diseases. Modulating angiogenic and lymphangiogenic pathways may provide a promising strategy for mitigating vascular decline and immune system dysfunction associated with aging. Exercise-induced endogenous angiogenesis and lymphangiogenesis can exert beneficial effects on physiological function, thereby representing a potential therapeutic paradigm for combating age-related decline and diseases. This review offers a thorough summary of the present knowledge regarding angiogenesis and lymphangiogenesis induced by exercise, encompassing the underlying mechanisms and the effects in different organs. In addition, it explores the potential of physical activity as a non-pharmacological intervention for anti-aging strategies and disease management, offering novel insights into the intersection of physical activity, aging, and disease progression.

Objective:To investigate the clinicopathological characteristics of lung transplantation and post-transplantation changes in patients with pneumoconiosis.Methods:A retrospective study was conducted to analyze the clinical and pathological data of 28 patients with pulmonary silicosis who underwent lung transplantation and were managed at the Department of Internal Medicine, Henan Provincial People′s Hospital, Zhengzhou, China from January 2015 to December 2024. Among them, 8 patients underwent lung biopsy 6-20 months after transplantation to evaluate the histopathological changes of the recipient and the donor lungs post-transplantation. The expression of relevant indicators was examined using immunohistochemical EnVision staining, while presence of microorganisms was assessed using histochemical special staining. The patients were all followed up.Results:Among the 28 patients with pneumoconiosis who underwent lung transplantation, 26 were male and 2 were female, with a male-to-female ratio of 13∶1. Their ages ranged from 23 to 68 years, median 50.0 (46.0, 53.5) years. They were diagnosed with pneumoconiosis at local occupational disease prevention and control centers for 3 to 15 years (mean, 9.65 years), including 13 left single lung transplants and 15 right single lung transplants. Gross examination showed fleshy nodules with irregular cystic cavities at the periphery. The cut surfaces exhibited gray-brown color and firm texture. Microscopically, most alveolar structures of the lung were obliterated, with nodular or diffuse proliferation of collagen fibers accompanied by hyaline degeneration. Focal massive carbon dust deposition and massive silicotic fibrosis were observed, surrounded by lung parenchyma with emphysematous changes and localized bullae formation. Seven patients underwent re-biopsy after transplantation that showed extensive infiltration of inflammatory cells. In 4 cases, microscopy revealed complete coagulative necrosis, with negative acid-fast staining and TB-DNA results. Of the 4 cases, 3 cases exhibited Aspergillus infection confirmed by Grocott′s methenamine silver and PAS stains, while 2 cases showed chronic bronchitis with squamous metaplasia. Follow-up revealed that 8 patients died of acute respiratory failure due to severe infection, while the remaining 20 demonstrated significant postoperative improvement in lung function.Conclusions:For patients with advanced pulmonary dust deposition disease who undergo lung transplantation, it is necessary to conduct standardized sampling and pathological assessment of the recipient lungs. In the early post-transplant period, the complications of re-biopsy tissues are mainly fungal infections. The combination of morphological manifestations and immunohistochemical detection is helpful to distinguish infection from rejection reactions. At the same time, it is essential to integrate clinical information and laboratory results to provide post-transplantation pathological assessment for individualized treatment.

Objective:To explore the clinical efficacy of staged reconstruction with anterolateral thigh flap (ALTF) for wrist-forearm soft tissue defects of electrical burns.Methods:A retrospective observational study was conducted on 10 patients who had wrist-forearm soft tissue defects after electrical burns and were admitted in the Department of Burns, Zhengzhou First People's Hospital from January 2019 to December 2022. The patients were 6 males and 4 females, aged 8 to 64 years. All the patients were third-and-fourth degree electrical burns. Debridement was performed to remove the necrotic tissues around the wound in stage I surgery. Area of the wound after debridement ranged from 15 cm×11 cm to 31 cm×20 cm. According to the condition of wrist-forearm injury, the wounds with relatively mild injury were retained. Free ALTF was used to cover the wound surface. Size of the flaps ranged from 16 cm×12 cm to 32 cm×21 cm. The descending branch of lateral circumflex femoral artery and the accompanying veins carried by the flap were anastomosed end-to-end with the radial artery and vein or ulnar artery and vein in the recipient site, respectively. Conditions of other vessels were explored. The great saphenous veins in a length of 10-18 cm was used to bridge the occluded arteries. The donor sites were covered by medium thick skin grafts from trunk. After survival of the flap, stage Ⅱ surgery was carried out to debride the wound temporarily retained in stage I surgery and to thin the flap, then had all the wound covered with the thinned flap. Follow-ups were conducted at outpatient clinic, and via telephone and WeChat interviews. The limb salvage, flap survival, vascular compromise and other complications, as well as the donor site healing were observed. The wound coverage rate of the thinned flap. The appearance of flap, donor site scar hyperplasia, the patient satisfaction with the shape and function of the donor site at 6 months after the stage Ⅱ surgery were evaluated. Likert scale was employed to evaluate the patient satisfaction. The Michigan Hand Outcomes Questionnaire (MHQ) and Disabilities of the Arm, Shoulder and Hand (DASH) were used to evaluate the upper limb function in daily life of the patients.Results:The limb salvages in the 10 patients were all successful, and the flaps survived without any postoperative event of vascular compromise or other complication. One patient had mild cyanosis at the edges of flap after surgery and regressed at 7 days later. One flap had poor blood circulation and partial necrosis. The thinned flaps covered the wound completely after the stage-Ⅱ flap thinning surgery. The postoperative follow-up period was 6.0-7.0 months. All skin grafts in the donor sites survived well. The thinned flaps of stage Ⅱ surgery achieved 100% in wound coverage rate. At 6 months after surgery, the colour and texture of the flaps were about the same as those of the normal skin of the upper limb. There were linear scars in both of donor and recipient sites. Four patients were satisfactory to the postoperative appearance and function of the donor site and 6 patients were very satisfactory. MHQ scores were 49-82 (mean, 74) points; DASH scores were 27-45 (mean, 32) points.Conclusion:Reconstruction of the wounds in wrist-forearm soft tissue defects of electrical burns with ALTF in staged surgery, can improve the function and aesthetics of the wrist-forearm. It is a good method.
