It is proposed that the pathogenesis of rheumatoid arthritis (RA) is centered on deficiency, dampness, and blood stasis, which interact with and evolve into one another during the onset and progression of the disease. The development of RA is closely associated with insufficiency of healthy qi and the interbinding of dampness and blood stasis. Accordingly, treatment emphasizes an integrated approach that combines tonifying deficiency, eliminating dampness, and resolving blood stasis, and is implemented in three main stages. In the initial stage, therapy focuses on supporting healthy qi, dispelling dampness, and relieving impediment, with modified Huangqi Guizhi Wuwu Decoction (黄芪桂枝五物汤) combined with Yiyiren Decoction (薏苡仁汤). In the active stage, treatment aims to eliminate dampness, resolve blood stasis, and unblock the collaterals, using modified Wutou Decoction (乌头汤) or Guizhi Shaoyao Zhimu Decoction (桂枝芍药知母汤). In the remission stage, therapy emphasizes strengthening the spleen and reple-nishing qi to prevent recurrence, with modified Shenling Baizhu Powder (参苓白术散) combined with Guipi Decoction (归脾汤).

ObjectiveTo investigate the effect of Toxoplasma gondii infection on copper metabolism in the kidneys of mice. MethodsA total of 80 7-8-week-old C57BL/6 female mice were randomly divided into four groups of 20 mice in each group after one week of adaptation, including Control group, Cu group, TgCtwh6 group and Cu+TgCtwh6 group. Mice that were not infected and fed with normal diet and water were used as the Control group; Mice fed with 1 g/kg of copper chloride processing diet and 0.1% copper chloride water for 60 consecutive days were used as Cu group; Mice infected with 25-30 TgCtwh6 cysts (one of the predominant genotype Chinese 1 in China) fed with normal diet and water were used as the TgCtwh6 group; mice infected with 25-30 TgCtwh6 cysts and fed with a processed diet containing 1 g/kg of copper chloride and water with 0.1% copper chloride for 60 consecutive days were used as the Cu+TgCtwh6 group. ICP-MS was used to determine the changes in copper content in kidney tissues. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of mouse kidney tissue. The number of apoptotic cells was observed by PI staining. Western blot was used to detect the protein expression levels of glutathione peroxidase 4 (GPX4) and superoxide dismutase (SOD1, SOD2). RT-qPCR was used to detect the mRNA expression of cuproptosis-related genes. ResultsPathological manifestations such as inflammatory cell infiltration in the Cu group and TgCtwh6 group were seen under the microscope, and the inflammatory infiltrating cells of the renal interstitial were reduced in the Cu+TgCtwh6 group, and the pathological manifestations

To analyze the clinical characteristics of acute diquat poisoning complicated by central nervous system injury (CNSI) and identify early risk factors, aiming to provide a theoretical basis for reducing mortality in diquat poisoning with CNSI. Clinical data from patients with acute diquat poisoning admitted to the Emergency Department of Fuyang People's Hospital Affiliated to Anhui Medical University between October 2019 and October 2024 were retrospectively analyzed. Patients were divided into CNSI and non-CNSI groups based on complications. Clinical features were compared between groups, and variables with statistical significance were subjected to binary logistic regression to identify independent risk factors for CNSI. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of these factors. A total of 63 eligible patients were included, with 18 deaths (28.57%) and 26 cases (41.27%) complicated by CNSI. The median time from diquat ingestion to CNSI onset was 15.5 (9.8, 31.3) hours. The CNSI group exhibited significantly higher mortality rates and required more frequent respiratory support and anti-shock therapy than the non-CNSI group (all CNSI is a fatal complication of acute diquat poisoning with high mortality. Diquat plasma concentration (≥549.95 μg/L) and APACHE Ⅱ score are independent risk factors for CNSI, and their combined application enhances predictive accuracy. These findings underscore the importance of early risk stratification and targeted interventions in high-risk populations.

Objective:To investigate the mechanism of Compound Mufurong Nasal Ointment in interfering with allergic rhinitis in young rats based on the Th1/Th2 cytokines and c-jun N-terminal kinase (JNK) signaling pathway.Methods:Totally 60 young SD male rats were divided into normal group, model group, experimental group, Western medicine group, and combination group according to random number table method, with 12 rats in each group. Except for the normal group, allergic rhinitis rat models were prepared by intraperitoneal injection of ovalbumin and nasal instillation of ovalbumin sensitization in all other groups of rats. After successful modeling, the normal group and the model group were given 0.9% sodium chloride injection 50 μl nasal drip, and the experimental group, the Western medicine group and the combination group were given compound Mufurong Nasal Ointment, fluticasone propionate nasal spray, compound Mufurong Nasal Ointment and fluticasone propionate nasal spray respectively. HE staining was used to observe the pathological morphology of nasal mucosal tissue; ELISA method was used to detect the levels of total IgE, interferon - γ (IFN - γ), IL-1 β, and IL-4 in the serum and nasal lavage fluid of rats in each group; Western blot was used to detect the expressions of JNK and p-JNK proteins in nasal tissues of rats in each group; Immunohistochemistry was used to detect the expressions of p-JNK and p-c-Jun proteins in nasal mucosal tissue.Results:Compared with model group, the levels of IgE, IL-1β and IL-4 in serum and nasal lavage solution of experimental group, western medicine group and combination group decreased ( P<0.05), IFN-γ level increased ( P<0.05); the expressions of JNK and p-JNK protein decreased ( P<0.05), and the expressions of p-JNK and p-c-Jun decreased ( P<0.05). Conclusion:Compound Mufurong Nasal Ointment may regulate Th1/Th2 cytokines through the JNK signaling pathway, inhibit Th2 over-expression, thereby reducing IgE, IL-1 β, IL-4 levels in serum and nasal lavage fluid, up-regulating IFN - γ levels, and intervening in the occurrence of allergic rhinitis.

Objective:To investigate the clinical characteristics and risk factors associated with secondary systemic capillary leak syndrome (SSCLS) induced by acute organophosphorus pesticide poisoning (AOPP). The goal is to enhance clinical understanding of this complication and provide a theoretical foundation for the early identification of high-risk patients and the optimization of individualized treatment strategies.Methods:Clinical data were collected from patients admitted to the Emergency Department of Fuyang People’s Hospital Affiliated to Anhui Medical University between October 2019 and October 2024, who were diagnosed with acute dichlorvos poisoning. The clinical features of SSCLS were described, and patients were categorized into SSCLS and non-SSCLS groups. Binary multivariate logistic regression analysis was conducted on statistically significant indicators to identify independent risk factors for SSCLS. Receiver operating characteristic (ROC) curves were generated to evaluate the predictive value of these factors.Results:Among the 96 patients studied, 37 (38.5%) developed SSCLS. The median time from toxin ingestion to the onset of SSCLS was 3.0 (2.0-5.0) hours. In the 14 SSCLS survivors, the median duration of SSCLS was 50.0 (24-72) hours, whereas in the 23 non-survivors, it was 24.0 (12.0-35.0) hours. The mortality rate in the SSCLS group (62.16%, 23/37) was significantly higher than that in the non-SSCLS group (1.69%, 1/59) ( χ2=44.343, P<0.001). Blood toxin analysis detected trichlorfon components in 92 patients (95.83%). Binary multivariate logistic regression identified APACHE Ⅱ score and trichlorfon concentration (≥706.35 ng/mL) as independent risk factors for SSCLS ( P<0.05). ROC analysis revealed that the combination of these two factors had a higher predictive value ( P<0.05). Conclusions:In the diagnosis and treatment of acute dichlorvos (organophosphorus pesticide) poisoning, particular attention should be given to the combined toxic effects of dichlorvos and trichlorfon, which can lead to SSCLS. The onset and progression of SSCLS are rapid, and the condition is associated with a high mortality rate. Both APACHE Ⅱ scores and trichlorfon concentrations (≥706.35 ng/mL) are independent risk factors for the development of SSCLS, and their combined use enhances predictive accuracy. Early identification of high-risk patients and timely administration of individualized treatment are critical for reducing mortality rates. This revised abstract maintains the original meaning while improving clarity, flow, and readability. It ensures that the key points are presented in a structured and professional manner, suitable for a clinical audience.
