ObjectiveTo explore the mechanism by which Zuoguiwan improves the pancreas development in the gestational diabetes mellitus (GDM) model by observing the effects of Zuoguiwan on the expression of key regulatory factors in different stages of pancreas development. MethodsPregnant Wistar rats were randomly assigned into blank, model, insulin detemir (20 U·kg-1) and Zuoguiwan (1.89 g·kg-1) groups (n=18). GDM was induced by peritoneal injection of streptozotocin on day 6.5 (E6.5d) in the embryonic stage, and the blank group was given an equal volume of sodium citrate buffer. The modeling performance was assessed by measuring the blood glucose of pregnant rats. Except the blank group and model group, pregnant rats in other groups were administrated with corresponding drugs from E9.5d to delivery. The random blood glucose of pregnant rats was monitored, and the embryos and offspring rats were measured for the length and weighed on E12.5d, E18.5d and day 21 after birth (B21d). The Lee's index of rats on B21d was calculated. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the fasting insulin (FINS) levels of B22d rats and the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) was calculated. The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (TBIL), total cholesterol (CHO), triglyceride (TG), high-density lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL) in E18.5d pregnant rats and B22d offspring were determined. The pathological changes in the pancreas of E12.5d, E18.5d and B22d rats were observed by hematoxylin-eosin (HE) staining. Western blot was used to determine the protein levels of pancreatic duodenal homeobox 1 (Pdx1), pancreas-specific transcription factor 1a (Ptf1a), and sex-determining region Y-box protein 9 (Sox9) in the pancreas of E12.5d embryos, Pdx1, Nkx2 homeobox 2 (Nkx2.2), and hairy and enhancer of split-1 (Hes1) in the pancreas of E18.5d embryos, and Pdx1, v-maf musculoaponeurotic fibrosarcoma oncogene homolog A (Mafa), and NK transcription factor-related homeobox gene family 6 locus 1 (Nkx6.1) in the pancreas of B22d rats. ResultsCompared with the blank group, the model group showed elevated blood glucose levels in pregnant rats on B0d, E9.5d, E12.5d, E15.5d, and E18.5d (P<0.05, P<0.01), decreased body weight and body length (P<0.01) and increased Lee's index in the offspring. In addition, the B22d offspring showed rising levels of FBG, FINS, HOMA-IR, AST, and TG (P<0.01), a declined level of HDL (P<0.01), and pancreatic acinous cells with edema and loose arrangement. The pregnant rats on E18.5d exhibited raised levels of ALT, AST, and TG (P<0.05, P<0.01) in the pancreas and a declined level of HDL (P<0.05). The E12.5d embryos showed up-regulated protein levels of Pdx1, Sox9, and Ptf1a in the pancreas (P<0.01) and the E18.5d embryos exhibited down-regulated protein levels of Pdx1, Nkx2.2, and Hes1 in the pancreas (P<0.01). The protein levels of Pdx1, Nkx6.1, and Mafa in the pancreas of B22d offspring were down-regulated (P<0.01). Compared with the model group, the insulin group exhibited lowered blood glucose in pregnant rats on B0d, E15.5d, and E18.5d (P<0.05, P<0.01). The offspring in all treatment groups showcased increased body weight and body length (P<0.01) and decreased Lee's index. The B22d offspring exhibited declined levels of FBG, FINS, and HOMA-IR in the insulin group (P<0.01) and lowered levels of FBG and HOMA-IR in the Zuoguiwan group (P<0.01). The B22d offspring in all the treatment groups showed reduced levels of ALT, AST, TBIL, CHO, TG, and LDL, a raised level of HDL, and alleviated edema of pancreatic acinous cells. The pregnant rats on E18.5d demonstrated declined levels of TG and ALT (P<0.05, P<0.01) and an elevated level of HDL (P<0.05). The pancreas of E12.5d embryos presented down-regulated protein levels of Pdx1 and Sox9 and an up-regulated protein level of Ptf1a in the insulin group (P<0.05). The pancreas of E12.5d embryos in the Zuoguiwan group presented down-regulated protein levels of Pdx1, Sox9, and Ptf1a (P<0.01). All the treatment groups showed up-regulated protein levels of Pdx1, Nkx2.2, and Hes1 in the pancreas of E18.5d embryos (P<0.01) and Pdx1, Nkx6.1, and Mafa in the pancreas of B22d embryos (P<0.05, P<0.01). ConclusionZuoguiwan can promote the growth and development and ameliorate the pathological changes in the pancreas of the offspring of GDM model by regulating the expression of Pdx1 pathway-related regulatory factors in different stages of pancreas development.

Myocardial ischemia-reperfusion injury (MIRI) is a major complication following coronary revascularization. Studies indicate that its pathophysiological mechanisms of MIRI are closely associated with oxidative stress, iron overload, inflammatory responses, and lipid peroxidation. Oxidative stress refers to an imbalance in redox homeostasis under pathological conditions, characterized by the abnormal accumulation of reactive oxygen species (ROS), which disrupts the dynamic balance between pro-oxidant systems and antioxidant defense networks. In recent years, traditional Chinese medicine (TCM) has demonstrated unique advantages in the prevention and treatment of MIRI due to its multi-target and multi-pathway antioxidant properties. Research reveals that TCM primarily exerts protective effects against oxidative stress-induced MIRI by regulating signaling pathways such as nuclear factor erythroid 2-related factor 2 (Nrf2), adenosine monophosphate-activated protein kinase (AMPK), phosphatidylinositol 3-kinase/protein kinase B (PI3K/Akt), nuclear factor kappa-B (NF-κB), Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3), and protein kinase C beta Ⅱ/nicotinamide adenine dinucleotide phosphate oxidase 2/reactive oxygen species (PKCβⅡ/NOX2/ROS). This article reviews recent literature on TCM monomers, compound formulas, and their active components, which alleviate oxidative stress to prevent and treat MIRI by modulating the aforementioned signaling pathways. It summarizes a concise overview of the molecular mechanisms by which oxidative stress-related signaling pathways lead to MIRI, discusses how TCM regulates these pathways to reduce oxidative stress-induced MIRI, and explores clinical application prospects and research challenges, aiming to provide a theoretical reference for the research and clinical management of MIRI.

OBJECTIVE To study the effects of peripheral blood-derived exosomes (Exo) intervened by Naozhenning (NZN) on injury of neuron cells HT22 induced by microglia BV-2 cells. METHODS Wistar rats were selected to prepare peripheral blood- derived Exo intervened by NZN (66.83 g/kg), referred to as NZN-Exo; peripheral blood-derived Exo intervened by normal saline and piracetam (PLXT, 1.62 g/kg) were prepared using the same method, denoted as KB-Exo and PLXT-Exo respectively, and all Exo were subsequently identified. Meanwhile, BV-2 cells were stimulated with 1 μg/mL lipopolysaccharide (LPS) to prepare LPS- stimulated supernatant, and non-LPS-stimulated supernatant was prepared following the same protocol. HT22 cells were divided into four groups: KB-Exo group (treated with non-LPS-stimulated supernatant+KB-Exo), model group (treated with LPS-stimulated supernatant+KB-Exo), PLXT-Exo group (treated with LPS-stimulated supernatant+PLXT-Exo), and NZN-Exo group (treated with LPS-stimulated supernatant+NZN-Exo), with the concentration of the corresponding Exo in all groups being 50 μg/mL. After 24 hours of culture, the proliferation of HT22 cells was detected by the CCK-8 assay and EdU assay; the apoptosis of HT22 cells was detected; the microstructure of HT22 cells was observed; the contents of interleukin-1β (IL-1β), IL-10, nuclear factor-κB (NF- κB), and tumor necrosis factor-α (TNF-α) in HT22 cells were measured, as well as the expression levels of TNF-α, NOD-like receptor thermal protein domain associated protein 3 (NLRP3), Caspase-1, B-cell lymphoma-2( Bcl-2), and Bcl-2-associated X protein (Bax). RESULTS KB-Exo, PLXT-Exo and NZN-Exo were successfully prepared, and all Exo exhibited typical cup-shaped contours and membrane-enclosed characteristics. Compared with KB-Exo group, model group showed significantly decreased cell proliferation rates (detected by CCK-8 and EdU), intracellular IL-10 levels, and Bcl-2 protein expression levels (P<0.05); while the cell apoptosis rate, intracellular levels of IL-1β, TNF-α, and NF-κB, as well as the expression levels of NLRP3, TNF-α, Caspase-1, and Bax proteins were significantly increased (P<0.05). Additionally, in the model group, the cells showed volume swelling, incomplete cell membrane, nucleolar rupture, significant swelling and deformation of mitochondria, and severe vacuolization. Compared with model group, the above quantitative indicators in the PLXT-Exo group and NZN-Exo group were significantly reversed (P<0.05), with large and round cell nuclei, intact nuclear membranes, and reduced mitochondrial vacuolization. CONCLUSIONS Peripheral blood-derived Exo intervened by naozhenning can alleviate the injury of neuronal cells HT22 by inhibiting inflammatory responses and cell apoptosis.

The paper introduces the reconstruction of Professor JI Laixi's modern paradigm of thought, "making use of various therapeutic methods". Professor JI Laixi reveres the concept of "integration of western medicine and TCM" and advocates the "combination of advantageous techniques of acupuncture and moxibustion". Guided by the concept of "combination of superiority, and coordinated adjustment", a multi-mode intervention is delivered in treatment, including the operation with the nine needles, relaxation with acupotomy, acupoint thread-embedding, Chinese herbal compounds and adjuvant therapy with western medicines, so as to obtain dynamic adjustment of multiple targets and levels, "taking effectiveness as the first priority". The pathway of clinical practice is determined and clear, which provides a paradigm of "upholding the right and innovating" for the modernization of acupuncture and moxibustion.

Inflammation represents a critical immune response triggered by cellular activities and inflammatory mediators following tissue damage. It plays a central role in the pathological progression of diverse diseases, including psychiatric disorders, cancer, and immunological conditions, rendering it an essential target for therapeutic intervention. Periodontitis, a prevalent oral inflammatory disease, is a leading cause of tooth loss and poses significant health challenges globally. Traditionally, inflammatory diseases such as periodontitis have been treated with systemic administration of synthetic chemicals. However, recent years have witnessed challenges, including drug resistance and microbial dysbiosis associated with these treatments. In contrast, natural products derived from Chinese medicine offer numerous benefits, such as high safety profiles, minimal side effects, innovative pharmacological mechanisms, ease of extraction, and multiple targets, rendering them viable alternatives to conventional antibiotics for treating inflammatory conditions. Numerous effective anti-inflammatory natural products have been identified in traditional Chinese medicine (TCM), including alkaloids, flavonoids, terpenoids, lignans, and other natural products that exhibit inhibitory effects on inflammation and are potential therapeutic agents. Several studies have confirmed the substantial anti-inflammatory and immunomodulatory properties of these compounds. This comprehensive review examines the literature on the anti-inflammatory effects of TCM-derived natural products from databases such as PubMed, Web of Science, and CNKI, focusing on terms like "inflammation", "periodontitis", "pharmacology", and "traditional Chinese medicine". The analysis systematically summarizes the molecular pharmacology, chemical composition, and biological activities of these compounds in inflammatory responses, alongside their mechanisms of action. This research seeks to deepen understanding of the mechanisms and biological activities of herbal extracts in managing inflammatory diseases, potentially leading to the development of promising new anti-inflammatory drug candidates. Future applications could extend to the treatment of various inflammatory conditions, including periodontitis.

ObjectiveTo study the effects of applying different microbial fertilizers on the growth and rhizosphere soil environment of Codonopsis pilosula and provide a theoretical basis for ecological cultivation of this medicinal plant. MethodsSeven groups were designed, including CK (no application of microbial fertilizer), T1 (Trichoderma longibrachiatum fertilizer), T2 (Bacillus subtilis fertilizer), T3 (Trichoderma viride fertilizer), T4 (compound microbial fertilizer), T5 (C. pilosula stems and leaves fermented with compound microbial fertilizer), and T6 (Scutellaria baicalensis stems and leaves fermented with T. viride fertilizer). The physiological indicators, yield, and quality of C. pilosula and the physicochemical properties, enzyme activities, and microbial diversity in the rhizosphere soil of different fertilizer treatments were measured. ResultsGroup T1 showed slight decreases in soluble protein content (SPC) and superoxide dismutase (SOD). Groups T2-T6 showed increases in physiological indicators such as proline (Pro), soluble solids content (SSC), SPC, catalase (CAT), and peroxidase (POD) and a decrease in malondialdehyde (MDA) in C. pilosula leaves. All the fertilizer treatments increased the yield of C. pilosula and the total polysaccharide content in the roots. T1, T2, T3, T4, and T5 increased the total flavonoid content in the roots. Meanwhile, T4 increased the total saponin content in the roots. All the fertilizer treatments reduced the pH and increased the electric conductivity (EC), soil organic matter (SOM), and alkaline nitrogen (AN) in the soil. T2 and T5 increased the available phosphorus (AP), and T3, T4, T5, and T6 increased the available potassium (AK) in the soil. All the fertilizer treatments increased the activities of urease, sucrase, and CAT in the soil. Except that T1 decreased the bacterial diversity in the soil, other fertilizer treatments significantly increased bacterial and fungal diversity in the soil. Different fertilizer treatments significantly affected the composition of bacterial and fungal communities in the soil. At the phylum level, the dominant bacterial phyla included Proteobacteria, Acidobacteriota, and Bacteroideta, and the dominant fungal phyla were Ascomycota, Mortierellomycota, and unclassified_fungi in the rhizosphere soil of C. pilosula after bacterial fertilizer treatment. At the genus level, unclassified Gemmatimonadaceae, Sphingomonas, and unclassified Vicinamibacteraceae were the dominant bacterial genera, while unidentified, unclassified Fungi, and unclassified Sordariomycetes were the dominant fungal genera in the rhizosphere soil. The results of redundancy analysis indicated that the main physicochemical factors affecting changes of microbial communities in the rhizosphere soil of C. pilosula were pH, EC, AK, AN, AP, and soil organic matter (SOM) in the soil. The correlation heatmap showed that Bryobacter had significantly positive correlations with EC, AK, and AN. There was a significantly negative correlation between Fusarium and SOM. In summary, applying an appropriate amount of microbial fertilizer can promote the growth and improve the rhizosphere soil environment of C. pilosula. ConclusionThe compound microbial fertilizer and the C. pilosula stems and leaves fermented with compound microbial fertilizer can improve the soil nutrients, growth, development, yield, and quality of C. pilosula, and thus they can be applied to the artificial cultivation of C. pilosula.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective:To compare the clinical efficacy of three-in-one procedure versus combined anterior cruciate ligament (ACL) and anterolateral structure (ALS) reconstruction in patients with ACL reconstruction failure.Methods:A total of 32 patients who underwent revision ACL reconstruction from January 2020 to March 2023 were included. The ipsilateral semitendinosus tendon, gracilis tendons, and the anterior half of the ipsilateral peroneus longus tendon, were harvested to constitute the autograft. In patients in whom the ipsilateral semitendinosus and gracilis tendons were unavailable, the bilateral anterior halves of the peroneus longus tendons were utilised. The ACL+ALS group, with bigger transplant graft (diameter >8 mm, n=17; males 13, females 4; mean age 28.29±7.90 years), ACL combined with ALS reconstruction were performed. The three-in-one group ( n=15; males 8, females 7; mean age 29.53±6.73 years) underwent additional iliotibial band (ITB) transposition for grafts with diameter <8 mm (excluding ITB). Operative time, intraoperative blood loss, and graft dimensions were compared. Graft healing was evaluated via postoperative MRI. Knee stability was evaluated via the Lachman test. Lysholm knee score, International Knee Documentation Committee (IKDC) score, knee injury and osteoarthritis outcome score (KOOS), and Tegner activity scale were compared preoperatively, 6-months postoperatively, and 12-months postoperatively, to assess knee function recovery. Results:Surgical parameters revealed that the ACL+ALS group had an operative time of 47.82±9.32 min, blood loss of 29.00±6.99 ml, graft diameter of 8.77±0.69 mm; three-in-one group had an operative time of 57.47±10.06 min, blood loss of 36.33±6.99 ml, graft diameter of 8.53±0.52 mm. Although graft diameter showed no significant intergroup difference ( t=1.065, P>0.05), the three-in-one group showed significantly longer operative times and greater blood loss ( t=2.815, P=0.009; t=2.746, P=0.010). The average follow-up time of the ACL+ALS group was 19.47±5.25 months (range, 12-28 months), whereas the three-in-one group was 20.40±6.50 months (range, 12-32 months). Postoperative MRI showed continuous and homogeneous graft signals in both groups at 6 and 12 months. Lachman test showed negative in 15 cases, grade I in 2 cases in the ACL+ALS group; and negative in 14 cases, grade I in 1 case in the three-in-one group. Both groups exhibited significant improvement from preoperative status ( P<0.001), with no intergroup difference ( P=1.000). Functional scores revealed that both groups showed significant improvement in Lysholm, IKDC, and Tegner scores at 6 and 12 months ( P<0.05 vs. preoperative), with no intergroup differences ( P>0.05). In KOOS subscales, the three-in-one group had significantly lower scores than the ACL+ALS group in pain (88.89±5.75 vs. 94.77±3.79 at 6 months; 89.26±5.93 vs. 96.41±3.22 at 12 months) and sports/recreation (71.33±12.32 vs. 83.53±9.31 at 6 months; 73.67±13.43 vs. 88.24±8.65 at 12 months; P<0.05). Conclusions:When the graft diameter is greater than or equal to 8 mm, both the three-in-one procedure and ACL combined with ALS reconstruction are effective for revision ACL reconstruction. However, patients who underwent three-in-one procedure experienced higher postoperative pain levels.
