ObjectiveTo investigate the effects of Maxing Kugan decoction (MKD) on inflammatory response and apoptosis in rats with oleic acid (OA)-induced acute lung injury (ALI) and explore its mechanism of action. MethodsSixty Sprague-Dawley (SD) rats were randomly assigned into six groups: a control group, a model group, a dexamethasone-treated group (2 mg·kg-1), and three MKD-treated groups at low, medium, and high doses (3.1, 6.2,12.4 g·kg-1). Each group was administered either an equivalent volume of normal saline or the corresponding concentration of MKD by gavage for seven consecutive days. The model group and each administration group were used to establish the ALI model by tail vein injection of OA (0.2 mL·kg-1). Twelve hours after modeling, blood gas analyses were conducted, and the wet-to-dry (W/D) weight ratio of lung tissue was measured for each group. Additionally, enzyme-linked immunosorbent assay (ELISA) was employed to quantify the levels of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the bronchoalveolar lavage fluid (BALF) of the rats. Cell damage and apoptosis in lung tissue were examined via hematoxylin-eosin (HE) staining and TdT-mediated dUTP-biotin nick end labeling (TUNEL) assays, and the results were subsequently scored. The expression levels of the p38 mitogen-activated protein kinase (p38 MAPK)/nuclear factor kappa-B (NF-κB) signaling pathway and apoptosis-related proteins and mRNAs were assessed using Western blot and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with the control group, the model group exhibited a significant decrease in partial pressure of oxygen (PaO2), blood oxygen saturation (SaO2), and oxygenation index (PaO2/FiO2), along with a marked increase in partial pressure of carbon dioxide (PaCO2) and lung W/D ratio (P<0.01). Additionally, levels of TNF-α, IL-6, and IL-1β in BALF were significantly elevated (P<0.01). Histopathological analysis of lung tissue showed significant inflammatory infiltration, tissue edema, alveolar septal thickening, and apoptosis of lung tissue. Pronounced increases were observed in the mRNA expression levels of p38 MAPK, NF-κB p65, inhibitor of NF-κB (IκBα), B-cell lymphoma-2 associated x protein (Bax), and Caspases-3, as well as the protein expression levels of p-p38 MAPK, p-NF-κB p65, p-IκBα, Bax, Caspases-3, and cleaved Caspases-3, while the mRNA and protein expression of Bcl-2 was downregulated (P<0.01). Compared with the model group, MKD significantly elevated PaO2, SaO2, and PaO2/FiO2 while reducing PaCO2 and W/D ratio in rats (P<0.01). It also greatly reduced TNF-α, IL-6, and IL-1β levels in BALF (P<0.01) and alleviated inflammatory infiltration, tissue edema, alveolar septal thickening, and apoptosis of lung tissue. Additionally, it downregulated the mRNA expression of p38 MAPK, NF-κB p65, IκBα, Bax, Caspases-3, as well as protein expression of p-p38 MAPK, p-NF-κB p65, p-IκBα, Bax, Caspases-3, and cleaved Caspases-3 in lung tissue (P<0.05, P<0.01), while significantly upregulating mRNA and protein expression of Bcl-2 (P<0.01). ConclusionMKD exerts a protective effect on OA-induced ALI rats, potentially through the regulation of the p38 MAPK/NF-κB signaling pathway to inhibit inflammation and apoptosis.

ObjectiveTo study the clinical characteristics and influencing factors of rheumatoid arthritis (RA) in the patients with cold dampness obstruction syndrome. MethodsThe RA patients treated in the Department of Traditional Chinese Medicine and Rheumatology of the China-Japan Friendship Hospital from August 2022 to June 2024 were selected. The demographic information, clinical data, laboratory test results, and traditional Chinese medicine (TCM) symptom information were collected for syndrome differentiation, on the basis of which the characteristics and influencing factors of cold dampness obstruction syndrome were analyzed. ResultsA total of 258 RA patients were selected in this study, including 88 (34.1%) patients with cold dampness obstruction syndrome, 53 (20.5%) patients with dampness and heat obstruction syndrome, 31 (12.0%) patients with wind dampness obstruction syndrome, 29 (11.2%) patients with liver-kidney deficiency syndrome, 19 (7.4%) patients with Qi-blood deficiency syndrome, 14 (5.4%) patients with phlegm-stasis obstruction syndrome, 15 (5.8%) patients with stasis obstructing collateral syndrome and 9 (3.5%) patients with Qi-Yin deficiency syndrome. The patients were assigned into two groups of cold dampness obstruction syndrome and other syndromes. The group of cold dampness obstruction syndrome had lower joint fever, 28-tender joint count (TJC28), and 28-joint disease activity score (DAS28)-C-reactive protein (CRP) and higher central sensitization, cold feeling of joints, fear of wind and cold, cold limbs, and abdominal distention than the group of other syndromes (P<0.05). The binary logistic regression analysis showed that central sensitization (OR 5.749, 95%CI 2.116-15.616, P<0.001) and DAS28-CRP (OR 0.600, 95% CI 0.418-0.862, P=0.006) were the independent factors influencing cold dampness obstruction syndrome in RA. ConclusionCold dampness obstruction syndrome is a common syndrome in RA patients. It is associated with central sensitization, cold feeling of joints, abdominal distension and may be a clinical syndrome associated with central sensitization.

ObjectiveTo explore the molecular mechanism by which gypenoside L (Gyp-L) promotes apoptosis and inhibits ovarian cancer (OC) through the FK506-binding protein (FKBP) prolyl isomerase 8 (FKBP8)/B-cell lymphoma-2 (Bcl-2) axis, with the piR-hsa-2804461 pathway as a breakthrough point. MethodsThe effects of different concentrations of Gyp-L and cis-platinum on the proliferation of OVCAR3 cells were determined by the cell count kit-8 method to identify the appropriate intervention concentration for subsequent experiments. OVCAR3 cells were allocated into blank, low-dose Gyp-L (Gyp-L-L, 50 µmol·L-1), high-dose Gyp-L (Gyp-L-H, 100 µmol·L-1), and cis-platinum (15 µmol·L-1) groups. The migration, colony formation, and apoptosis of OVCAR3 cells were detected by the cell scratch assay, colony formation assay, and flow cytometry, respectively. The mRNA levels of piR-hsa-2804461 and FKBP8/Bcl-2 axis-related genes in OVCAR3 cells were determined by Real-time PCR, and the expression levels of FKBP8/Bcl-2 axis-related proteins were determined by simple Western blot. Further, an OVCAR3 cell model with piR-hsa-2804461 knocked out was constructed. The cells were allocated into blank, NC-inhibitor, inhibitor, NC-inhibitor+Gyp-L, and inhibitor+Gyp-L groups. The colony formation of OVCAR3 cells was detected by the colony formation assay. The mRNA levels of piR-hsa-2804461 and FKBP8/Bcl-2 axis-related genes and the expression levels of FKBP8/Bcl-2 axis-related proteins were determined by Real-time PCR and simple Western blotting, respectively. ResultsGyp-L inhibited the migration and proliferation (P<0.01), promoted the apoptosis (P<0.05), up-regulated the mRNA level of piR-hsa-2804461 (P<0.05), and down-regulated the mRNA and protein levels of FKBP8 and Bcl-2 (P<0.05) in OVCAR3 cells. Furthermore, Gyp-L increased the mRNA and protein levels of Bcl-2-associated X protein (Bax), cysteinyl aspartate-specific proteinase (Caspase)-3, and Caspase-9, which are related to the FKBP8/Bcl-2 axis (P<0.05). ConclusionGyp-L may promote apoptosis by regulating the piR-hsa-2804461/FKBP8/Bcl-2 axis, thus affecting the occurrence of ovarian cancer.

Purpose:
To investigate the therapeutic potential of eliminating insulin-like growth factor-binding protein 5 (IGFBP5) expression in improving erectile function in mice with cavernous nerve injury (CNI)-induced erectile dysfunction (ED).
Materials and Methods:
Eight-week-old male C57BL/6 mice were divided into four groups: a sham-operated group and three CNI-induced ED groups. The CNI-induced ED groups were treated with intracavernous injections 3 days before the CNI procedure.These injections included phosphate-buffered saline, scrambled control short hairpin RNA (shRNA), or shRNA targeting mouse IGFBP5 lentiviral particles. One week after CNI, erectile function was evaluated and the penile tissue was then harvested for histological examination and western blot analysis. Additionally, the major pelvic ganglia (MPG) and dorsal root ganglia (DRG) were cultured for ex vivo neurite outgrowth assays.
Results:
Following CNI, IGFBP5 expression in the cavernous tissues significantly increased, reaching its peak at day 7. First, ablation of IGFBP5 expression promotes neurite sprouting in MPG and DRG when exposed to lipopolysaccharide. Second, ablating IGFBP5 expression in CNI-induced ED mice improved erectile function, likely owing to increased neurovascular contents, including endothelial cells, pericytes, and neuronal processes. Third, ablating IGFBP5 expression in CNI-induced ED mice promoted neurovascular regeneration by increasing cell proliferation, reducing apoptosis, and decreasing Reactive oxygen species production. Finally, western blot analysis demonstrated that IGFBP5 ablation attenuated the JNK/c-Jun signaling pathway, activated the PI3K/AKT signaling pathway, and increased vascular endothelial growth factor and neurotrophic factor expression.
Conclusions
Ablating IGFBP5 expression enhanced neurovascular regeneration and ultimately improved erectile function in CNI-induced ED mice.

Rheumatoid arthritis (RA) is an autoimmune disease characterized primarily by erosive arthritis, with a high prevalence and disability rate. Although significant progress has been made in the treatment of RA in recent years, challenges such as suboptimal efficacy, drug resistance, severe side effects, and high costs of long-term treatment remain, especially for patients in the early stages of RA, as well as those with RA complications, comorbidities, and severe conditions. Hosted by the China-Japan Friendship Hospital and organized by the Youth Committee of the China Association of Chinese Medicine, the 27th session of the Clinical Dominant Disease Series (Rheumatoid Arthritis) Youth Salon invited nearly 20 experts and scholars from traditional Chinese medicine (TCM), western medicine, and interdisciplinary fields to actively discuss the clinical needs of modern medicine and the advantageous stages and aspects of TCM in RA. Experts at the salon agreed that TCM has unique advantages in the treatment of RA, especially during the early stage, periods of low to moderate disease activity, remission phase, and in addressing complications and comorbidities. TCM can achieve both prevention and treatment by regulating the immune system and restoring immune homeostasis. The integrated approach of traditional Chinese and western medicine demonstrates significant advantages in active RA, refractory cases, and stages with severe complications, by rapidly controlling disease progression, alleviating symptoms, enhancing the quality of life, and facilitating recovery. Given the frequent occurrence of multiple comorbidities in RA, TCM shows potential in regulating immunity, alleviating symptoms, and improving physical constitution, which provides new insights into the comprehensive treatment of RA with comorbidities. However, high-quality clinical studies on integrated traditional Chinese and western medicine in RA are still lacking. It is necessary to establish large-scale clinical cohorts and biological databases to provide a scientific basis for the development of precision-targeted therapies and clinical treatment protocols. In the future, individualized treatment strategies integrating traditional Chinese and western medicine are expected to become an important direction for improving the quality of life in RA patients.
