Objective To investigate the efficacy of early, short-term, low-dose corticosteroid administration for the prevention and treatment of early acute lung injury (EALI) in patients undergoing thoracoscopic lobectomy. Methods A retrospective analysis was conducted on the clinical data of patients who underwent thoracoscopic lobectomy at the Department of Thoracic and Cardiovascular Surgery, Taihe Hospital, Hubei University of Medicine, from January 2019 to January 2022. Patients were divided into an early steroid therapy group and an observation group based on whether they received corticosteroids in the early postoperative period. In the early steroid therapy group, in addition to standard postoperative care, patients received a low-dose intravenous push of methylprednisolone (80-120 mg/d) for 3 consecutive days. In the observation group, patients received standard postoperative care without intravenous corticosteroids for the first 3 days. Chest plain CT scans were performed on postoperative day (POD) 1 and POD 3 or 4 to evaluate lung injury. CT scores and the incidence of postoperative EALI were recorded. Results A total of 521 patients were included (268 males, 253 females; age range: 11-80 years). There were 318 patients in the observation group and 203 in the early steroid therapy group. On POD 1, the incidence of EALI was 16.0% in the observation group and 13.8% in the early steroid therapy group, with no statistical difference (P=0.486). Correspondingly, there was no statistical difference in chest CT scores among EALI-positive patients between the two groups (P=0.927). On POD 3-4, the incidence of EALI was significantly lower in the early steroid therapy group (22.7%) compared to the observation group (33.6%) (P=0.007). Although chest CT scores among EALI-positive patients were lower in the early steroid therapy group, the difference was not statistically significant (P=0.377). The overall incidence of EALI within the first 4 postoperative days was significantly lower in the early steroid therapy group (26.1%) than in the observation group (37.4%) (P=0.007). Radiological progression (defined as new-onset EALI or progression of existing EALI) occurred in 14.8% of the early steroid therapy group, significantly lower than the 28.9% in the observation group (P<0.001). The early steroid therapy group had a shorter postoperative length of stay (P<0.001), while there was no statistical difference in the incidence of poor wound healing between the groups (P=0.762). Conclusion Early postoperative corticosteroid use effectively reduces the incidence of EALI on POD 3-4, lowers the risk of radiological progression, and decreases the overall incidence of postoperative EALI. This is achieved without prolonging the length of stay or increasing the risk of poor wound healing. Therefore, early administration of low-dose corticosteroids is beneficial in suppressing the occurrence and progression of EALI. Its early use is recommended for patients at high risk for postoperative EALI.

4.Drug‑drug interaction mechanisms and clinical challenges in antithrombotic therapy for acute ischemic stroke
Journal of Apoplexy and Nervous Diseases 2026;43(3):204-213
Objective To systematically summarize the pharmacological characteristics and clinical applications of antithrombotic medications in ischemic stroke, as well as their interactions with drugs used for common comorbidities, and to provide a reference for clinical medication. Methods Based on the UpToDate database and the integration with pharmacokinetic and pharmacodynamic mechanisms, this study systematically analyzed interactions between antithrombotic agents and between antithrombotics and drugs for comorbid conditions. Interactions were categorized and evaluated based on the level of evidence. Results The distinct pharmacological mechanisms of different antithrombotic drugs determine their patterns of drug-drug interactions. Combination antithrombotic therapy produces synergistic antithrombotic effects but increases the risk of hemorrhage. Extensive interactions exist when antithrombotics are co-administered with medications for cardiovascular diseases, metabolic disorders, neuropsychiatric conditions, and infectious diseases. These interactions primarily involve the cytochrome P450 enzyme system and P-glycoprotein pathways, which may compromise therapeutic efficacy or elevate the risk of bleeding and thrombosis. Conclusion Multiple drug interactions are present in antithrombotic therapy for ischemic stroke. In clinical practice, it is essential to consider the impact of pharmacokinetic and pharmacodynamic mechanisms. By integrating tools such as pharmacogenomics and therapeutic drug monitoring, individualized medication strategies should be implemented to achieve an optimal balance between antithrombotic efficacy and safety.

This paper summarizes Professor WANG Yaoxian's experience in treating diabetic kidney disease (DKD) from the perspective of spleen and stomach based on the "internal heat leading to concretions" theory. It is considered that internal heat leading to concretions constitutes the core pathogenesis of DKD, with the spleen and stomach serving as the source of internal heat; therefore, treatment should be based on regulating the spleen and stomach. In the early stage of DKD, dysfunction of the spleen and stomach leads to the initial generation of internal heat. Common syndrome patterns include gastrointestinal heat accumulation and constrained heat in the liver and stomach, for which modified Gegen Qinlian Decoction (葛根芩连汤) can be used to clear heat bind while modified Dachaihu Decoction (大柴胡汤) is used to clear stomach and soothe liver, respectively. In the middle stage of DKD, weakness of the spleen and stomach results in the initial formation of concretions and conglomerations. Common patterns include spleen deficiency with prevalence of dampness and deficiency of both the spleen and kidney. Treatment emphasizes strengthening the spleen and resolving dampness, raising yang and boosting the stomach with modified Shengyang Yiwei Decoction (升阳益胃汤), or supplementing spleen and boosting kidney, dissipating bind and dispe-ring concretions with modified Shenqi Dihuang Decoction (参芪地黄汤), respectively. In the late stage of DKD, it is characterized by spleen and stomach depletion, and rampant accumulation of turbidity and toxin, and the common syndrome patterns are damp-turbidity obstruction in the middle jiao (焦) and spleen-kidney yang deficiency. Treatment aims to remove turbidity and harmonize the stomach, or to warm the kidney and strengthen the spleen while elimina-ting turbidity, using modified Dahuang Gancao Decoction(大黄甘草汤) and Jupi Zhuru Decoction (橘皮竹茹汤) or modified Baoyuan Decoction (保元汤) and Lizhong Decoction (理中汤), respectively. In clinical practice, appropriate formulas and medications are flexibly selected according to specific syndromes.
6.XU Jingfan's Experience in Treating Spleen and Stomach Diseases with Shichangpu (Rhizoma Acori Tatarinowii):Based on the Theory of 'Aromatics Acting on the Spleen'
Journal of Traditional Chinese Medicine 2026;67(12):1258-1261
This article summarized the clinical experience of professor XU Jingfan,a traditional Chinese medicine (TCM) master, in treating spleen and stomach diseases with aromatic herb Shichangpu (Rhizoma Acori Tatarinowii), based on the theory of 'aromatics acting on the spleen'. Shichangpu is commonly combined with Peilan (Herba Eupatorii) to aromatically awaken the spleen, and self-made Xingpi Kaiwei Formula (醒脾开胃方) can be used for postprandial distress syndrome of the spleen-stomach disharmony type. It is paired with Diyu (Radix Sanguisorbae) to resolve turbidity and promote wound healing, with a self-made Changyu Decoction (菖榆煎) for retention enema in chronic colitis and inflammatory bowel disease. When paired with Yujin (Radix Curcumae), it can be used to promote qi and resolve constraint, and can be combined with modified Sini Powder (四逆散) for epigastric pain of liver-stomach disharmony type. Paired with Fangfeng (Radix Saposhnikoviae) to dispel wind and resolve dampness, and together with Tongxie Important Formula (痛泻要方), it is used to treat diarrhea-predominant irritable bowel syndrome of liver constraint and spleen deficiency type. It is paired with Yizhiren (Fructus Alpiniae Oxyphyllae) for its warming and astringing properties, and together with modified Linggui Zhugan Decoction (苓桂术甘汤) for phlegm-rheum due to spleen-stomach yang deficiency type. Clinically, great importance is also attached to tongue inspection related to Shichangpu, closely focusing on the pathogenesis of internal accumulation of damp turbidity in the middle jiao (焦). Moreover, when treating spleen and stomach diseases, the dosage should be light and flexible.

Objective: To evaluate the risk of donation-related adverse reactions, donation behavior, and contributions to the blood supply among donors aged 56-65 years following extension of the upper age limit for voluntary blood donation, and to provide real-world evidence for optimizing blood donation age policies in China. Methods: A multicenter retrospective cohort was established using blood donation databases from Hainan, Shenzhen, and Jiangxi. A total of 1 180 767 donors contributing 2 020 407 whole-blood and apheresis donations were included. Donations were classified by donor age at each donation into the 18-55-year and 56-65-year groups. Generalized estimating equation (GEE) models were used to compare the risks of overall, local, and systemic donation-related adverse reactions between the two age groups. Restricted cubic spline analysis was used to assess the continuous association between donor age and the risk of overall adverse reactions. Poisson GEE models were used to compare annual donation frequency, and donation participation and contributions to the blood supply among donors aged 56-65 years were evaluated. The study was approved by the Ethics Committee of the Institute of Blood Transfusion, Chinese Academy of Medical Sciences (No.2025012) and registered with the Chinese Clinical Trial Registry (ChiCTR2500114960). Results: A total of 1 960 711 donations were included in the 18-55-year group and 59 696 in the 56-65-year group. The overall donation-related adverse reaction rates were 3.890‰and 0.704‰, respectively. Multivariable GEE analysis showed that, compared with donors aged 18-55 years, those aged 56-65 years had lower risks of overall adverse reactions (adjusted OR=0.294, 95%CI: 0.217-0.398, P<0.001) and systemic adverse reactions (adjusted OR=0.163, 95%CI: 0.101-0.263, P<0.001), whereas no statistically significant difference was observed in the risk of local adverse reactions (adjusted OR=1.337, 95%CI: 0.487-3.670, P=0.573). Donor age was nonlinearly associated with the risk of overall adverse reactions (P overall<0.001, P nonlinear<0.001), with the risk generally decreasing with increasing age between 18 and 65 years. The mean annual donation frequency was higher among donors aged 56-65 years than among those aged 18-55 years (1.63 vs 1.24 donations per year; adjusted IRR=1.34, 95%CI: 1.30-1.39, P<0.001). During the study period, donors aged 56-65 years contributed 2.95% of all donations; their whole-blood donations and whole-blood collection volume accounted for 2.36% and 2.37% of the corresponding totals, respectively. Conclusion: Under current health screening and standardized donor management, donors aged 56-65 years did not show an increased risk of short-term donation-related adverse reactions and demonstrated a higher annual donation frequency, together with a measurable contribution to the blood supply. These findings support appropriately extending the upper age limit for voluntary blood donation under strict health screening to broaden the donor pool and supplement the blood supply.
