Traditional treatment for type 1 diabetes mellitus (T1DM) primarily involves insulin replacement, yet some patients encounter issues such as significant blood glucose fluctuations, high risk of hypoglycemia, and weight gain. In recent years, the adjuvant therapeutic role of non-insulin hypoglycemic drugs in T1DM has gradually gained attention. This article reviews the mechanisms of action and clinical research progress of five types of non-insulin hypoglycemic drugs in the treatment of T1DM: amylin analogues (pramlintide), biguanides (metformin), sodium-glucose co-transporter 2 inhibitor, dipeptidyl peptidase-4 inhibitor, and glucagon-like peptide-1 receptor agonist. It is found that these drugs can enhance clinical benefits for T1DM patients by improving insulin sensitivity, delaying gastric emptying, promoting urinary glucose excretion, and regulating incretin levels, thereby reducing glycated hemoglobin levels, decreasing insulin dosage, and managing body weight. Simultaneously, these drugs also present limitations such as low patient compliance due to complex dosing regimens, increased risk of diabetic ketoacidosis, and heterogeneity in glycemic control. Future research could focus on developing individualized treatment strategies, combining pharmacogenomics with novel biomarkers to precisely identify subpopulations of patients who may benefit, and delving into the potential value of these drugs in delaying diabetic vascular complications and improving patients’ quality of life.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance, while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine (TCM) has a long history in the prevention and management of this condition, demonstrating eight distinct advantages, including systematic theoretical foundation, diversified therapeutic approaches, definite therapeutic efficacy, high safety profile, good patient compliance, comprehensive intervention strategies, emphasis on prevention, and stepwise treatment protocols. Additionally, TCM is characterized by six distinctive features: the use of natural medicinal substances, non-invasive external therapies, integration of medicinal dietetics, simple exercise regimens, precise syndrome differentiation, and diverse dosage forms. By combining internal and external treatments, TCM facilitates individualized regimen adjustment and holistic regulation, demonstrating remarkable effects in improving obesity-related metabolic indicators, regulating constitutional imbalance, and promoting healthy behaviors. However, challenges remain, such as inconsistent operational standards, insufficient high-quality clinical evidence, and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment, conducting multicenter randomized controlled trials, and fostering interdisciplinary integration, so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

In recent years, research on stem cell therapy in the field of lung transplantation has gradually increased, demonstrating its potential in improving the outcomes of lung transplantation. As a treatment option for end-stage lung diseases, lung transplantation faces challenges such as scarcity of donor organs, postoperative complications and rejection. Stem cells, with their self-renewal and multi-directional differentiation capabilities, have emerged as strong candidates for alternative or adjunctive treatments. Current studies show that embryonic stem cells and umbilical cord mesenchymal stem cells play significant roles in lung tissue regeneration and immune regulation. However, stem cell therapy still needs to overcome issues such as the selection of cell sources, low survival rates after transplantation and unclear long-term efficacy in clinical applications. Future research should focus on exploring new stem cell sources, improving transplantation techniques and establishing efficacy evaluation systems.

Gout is a crystal-associated arthropathy caused by the deposition of monosodium urate crystals and is closely related to purine metabolic disorders and impaired uric acid excretion. It is clinically characterized by hyperuricemia, recurrent joint swelling and pain, and tophus formation. The disease course is divided into three stages: The hyperuricemia stage, acute attack stage, and chronic gouty arthritis stage. Modern medicine has reached a consensus on its pathology, but traditional Chinese medicine (TCM) lacks a systematic stage-specific understanding of gout pathogenesis and its underlying mechanisms, making it difficult to guide precise syndrome differentiation and treatment. By integrating classical TCM theory, clinical practice, and modern medical understanding, and drawing upon descriptions of Bi syndrome caused by endogenous dampness and turbidity in classical texts such as Huangdi Neijing·Ling Shu and Synopsis of the Golden Chamber, our team proposes the pathogenic concept of gout as ''endogenous dampness leading to Bi syndrome'' and the core pathogenesis of ''spleen deficiency with internal retention of dampness-turbidity''. We systematically elucidate the evolution of pathogenesis across different stages and corresponding therapeutic strategies. This study posits that metabolic byproducts such as urate fall under the category of ''endogenous pathogenic dampness-turbidity''. When genetic or dietary factors lead to metabolic abnormalities, it manifests as ''spleen deficiency with impaired transport and transformation'', resulting in ''internal retention of pathogenic dampness-turbidity''. When damp-turbidity stagnates in the blood vessels, serum uric acid levels rise. When it stagnates in the viscera and limbs, monosodium urate crystals deposit in the joints. Triggered by precipitating factors, this leads to gout attacks—the core pathological process of ''endogenous dampness leading to Bi syndrome''. Based on this theory, the stage-specific pathogenic characteristics of gout are proposed: The hyperuricemia stage is characterized by ''spleen deficiency with impaired transport and transformation, internal retention of pathogenic dampness-turbidity'', the acute attack stage is primarily marked by ''dampness-turbidity and static heat obstructing the limbs and joints'', while the chronic stage is defined by ''spleen deficiency with internal retention of pathogenic dampness-turbidity, intermingled with phlegm-stasis binding''. The treatment principle centers on ''strengthening the spleen and draining dampness'' throughout all stages. During the hyperuricemia stage, treatment focuses on ''strengthening the spleen, draining dampness, and eliminating turbidity''. In the acute attack stage, the treatment should "strengthen the spleen, drain dampness, clear heat, eliminate turbidity, alleviate swelling, and relieve pain''. In the chronic stage, the treatments emphasizes to ''strengthen the spleen, drain dampness, transform turbidity, clear heat, resolve phlegm, and activate blood circulation''. This approach has yielded favorable therapeutic outcomes in clinical practice. This theoretical system clarifies the nature of gout as ''spleen deficiency being the root, dampness-turbidity being the secondary manifestation'' and systematically analyzes its pathogenesis evolution process and characteristics. The constructed stage-based treatment protocol has been validated through clinical and basic research, providing systematic theoretical guidance and a practical framework for the precise TCM management of gout, thereby promoting the modernization of TCM pathogenesis theory related to gout.

ObjectiveThis paper aims to observe the effect of Huazhuo Sanjie Chubi prescription (HSCD) on the gouty bone erosion model rats and investigate its action mechanism. MethodsThirty-six two-month-old male SD rats were randomly divided into the blank group with nine rats and the modeling group with 27 rats. The rats in the modeling group were administered hypoxanthine solution at 300 mg·kg-1·d-1 and potassium oxonate solution at 250 mg·kg-1·d-1, combined with intra-articular injection of 200 μL monosodium urate (MSU) crystal suspension at 25 g·L-1 into the right ankle joint (joint injection once every three days), so as to induce the gouty bone erosion model. After four weeks of modeling, three rats were selected from these two groups to validate the model. The modeled 24 rats were randomly divided into the model group, HSCD group (10.35 g·kg-1·d-1), allopurinol group (20 mg·kg-1·d-1), and inhibitor group (LY294002, 10 mg·kg-1·d-1), with six rats per group. Except for the blank group, rats in all other groups continued to receive hypoxanthine solution at 300 mg·kg-1 and potassium oxonate solution at 250 mg·kg-1 via gavage concurrently with administration to maintain modeling intervention. The rats in the HSCD group and allopurinol group received administration by gavage at the above doses. The rats in the inhibitor group received an intraperitoneal injection at the above dose. The rats in the blank group and model group received saline (10.35 g·kg-1·d-1) by gavage for four consecutive weeks. After administration, ankle joint swelling of the rats in all groups was observed, and the diameters were measured. Bone volume fraction (BV/TV) and bone surface area to bone volume (BS/BV) were observed and quantitatively analyzed by Micro-CT. Histopathological changes in the ankle joint were observed by hematoxylin-eosin (HE) staining and safranin O-fast green staining. The uric acid in the rats' serum was determined by enzyme colorimetry. The levels of inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6 were measured by enzyme-linked immunosorbent assay (ELISA). The protein expressions of receptor activator of nuclear factor-κB ligand (RANKL) and phosphorylated (p)-phosphatidylinositol-3-kinase (PI3K) in ankle joint tissues of rats were detected by immunofluorescence staining. The mRNA levels of the proteins related to the bone erosion, including RANKL, tartrate-resistant acid phosphatase

ObjectiveTo investigate the effects of different fermentation methods and times on the fungal flora and chemical composition of Aurantii Fructus, in order to obtain the optimal fermentation conditions and flora structure, and to ensure the stability and controllability of the fermented varieties. MethodsScanning electron microscopy was used to observe and analyze the colony characteristics on the surface of Aurantii Fructus under different fermentation conditions. Internal transcribed spacer 2(ITS2) high-throughput sequencing, combined with fungal community diversity analysis and fungal community structure analysis, were used to obtain the fungal flora microbial categories of Aurantii Fructus under the conditions of traditional pressure-shelf fermentation and non-pressure-shelf natural fermentation for 7, 14, 21 d(numbered Y1-Y3 for the former, and numbered F1-F3 for the latter), respectively. At the same time, the chemical components in the fermentation process were detected by ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS), combined with principal component analysis(PCA), partial least squares-discriminant analysis(PLS-DA) and compound retention time, parent ions, characteristic fragment ions and other information, the differential compounds between the different fermentation samples were screened and identified. ResultsThe analysis of fungal community diversity showed that the dominant flora did not change at different fermentation time points in the traditional pressure-shelf fermentation method, while in the non-pressure-shelf natural fermentation method, there was a significant difference with the fermentation process, and at the genus level, the dominant genus of samples Y1, Y2, Y3 and F2 was Aspergillus, while the dominant genera of samples F1 and F3 were both Rhizopus. This indicated that the microbial growth environment provided by the traditional fermentation method was more stable, and the microbial community structure was more stable, which was more conducive to the stable and controllable fermentation process and fermented products. A total of 155 compounds were identified by compositional analysis, including 70 flavonoids, 38 coumarins, 10 alkaloids, 34 organic acids and 3 other compounds. After fermentation, two new components of ribalinine and pranferin were produced. Different fermentation conditions also brought about differences in chemical composition, multivariate statistical analysis obtained 26 differential compounds under two different fermentation methods, mainly including flavonoids, organic acids and coumarins. Comprehensively, the microbial community structure of samples fermented by the traditional pressure-shelf method of Aurantii Fructus for 14 d was stable, the species richness was high and the overall content of differential compounds was high, which was the optimal processing condition. ConclusionCompared with non-pressure-shelf natural fermentation, the traditional method has obvious advantages in terms of the stability of the microbial community structure and the content of chemical compounds, and the optimal condition is 14 days of fermentation. This study is helpful to promote the quality stability and fermentation bioavailability of fermented products of Aurantii Fructus, as well as to provide an experimental basis for the further improvement of the quality control methods of this variety.
