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.

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.

Objective:To explore the predictive value of the combined application of total prostate-specific antigen (TPSA), vascular endothelial growth factor A (VEGF-A), and interleukin (IL) in predicting postoperative biochemical recurrence in patients with prostate cancer.Methods:This study adopted a retrospective cohort research method. 202 male prostate cancer patients who visited Xi′an Gaoxin Hospital from April 2021 to January 2024 were selected as the research subjects. The age of the patients was 68(64, 71) years, and their postoperative conditions were classified into the non-recurrence group ( n=144) and the biochemical recurrence group ( n=58). The general clinical data and serumological test indicators SA, free prostate-specific antigen (FPSA), VEGF-A, IL-6, IL-17] were detected and compared between the two groups. Quantitative data with normal distribution were expressed as mean±standard deviation, and the comparison between groups was performed using the independent sample t-test; non-normal distribution quantitative data were expressed as M( Q1, Q3), and the comparison between groups was performed using the Mann-Whitney U test. The comparison between groups of count data was performed using the chi-square test. Through Spearman correlation analysis and multivariate Logistic regression analysis, the risk factors for biochemical recurrence after surgery in prostate cancer patients were screened out, and the efficacy of the combined prediction model based on TPSA, VEGF-A, and IL-17 was evaluated by receiver operating characteristic (ROC) curve, decision curve (DCA), and calibration curve. Results:The average tumor diameter, proportion of positive surgical margins, proportion of seminal vesicle invasion, and proportion of patients with Gleason score 3-5 in the biochemical recurrence group were significantly higher than those in the non-recurrence group ( P<0.05). The serumological indicators TPSA, VEGF-A, IL-6, IL-17 in the biochemical recurrence group were 44.28 (42.37, 48.57) ng/mL, (28.24±3.99) ng/mL, (39.14±2.95) ng/L and (66.64±6.04) pg/mL; those in the non-recurrence group were 41.25 (36.61, 43.56) ng/mL, (23.52±3.75) ng/mL, (37.19±4.19) ng/L, and (57.31±6.63) pg/mL. The biochemical recurrence group was higher than the non-recurrence group, and the difference was statistically significant ( P<0.05). Spearman correlation analysis and Logistic regression analysis found that TPSA, VEGF-A, and IL-17 were risk factors for biochemical recurrence after surgery in prostate cancer patients ( P<0.05); the DCA curve and calibration curve indicated that the combined prediction model based on TPSA, VEGF-A, and IL-17 had good accuracy (Hosmer-Lemeshow P=0.421), and the ROC curve suggested that the efficacy of the above indicators combined for predicting biochemical recurrence after surgery in prostate cancer patients was higher [AUC (95% CI)=0.899 (0.832-0.966)], and higher than the independent predictive efficacy of each indicator. Conclusion:Continuous monitoring of serum TPSA, VEGF-A, and IL-17 levels can effectively predict the risk of postoperative recurrence in prostate cancer patients and also provide biological markers for preventing disease recurrence.

Alzheimer's disease(AD)is a progressive neurodegenerative disease with hidden onset.Recent researches have shown that apolipoprotein E4(APOE4)is a high-risk genetic factor of AD,and the clinical symptoms in APOE4 genotype AD patients are closely related to metabolic disorders.This paper reviewed the role of APOE4 in the pathogenesis of AD,and it is indicated that APOE4 contributes to the injury of the cerebral blood-brain barrier,is associated with the disorder of cerebral glucose and lipid metabolism,and leads to the damage of the scavenging ability of microglia.Moreover,this paper explored the approach of early intervention of AD with traditional Chinese medicine(TCM)based on the APOE4 pathogenesis.Based on the pathogenesis of AD being deficiency in origin and excess in superficiality,and under the guidance of the principle of prevention before illness in TCM,it is proposed that early TCM intervention for APOE4 genotype AD patients with metabolic disorders can be performed through improving the phlegm-dampness constitution,by focusing on insulin resistance-related indicators,and with traditional Chinese drug therapy based on syndrome differentiation alone or together with comprehensive management of exercises,diet control and drug interventions,thus to reduce or delay the onset of APOE4 genotype AD.

This study investigates the pharmacokinetics and metabolic characteristics of three marine-derived piericidins as potential drug leads for kidney disease: piericidin A (PA) and its two glycosides (GPAs), glucopiericidin A (GPA) and 13-hydroxyglucopiericidin A (13-OH-GPA). The research aims to facilitate lead selection and optimization for developing a viable preclinical candidate. Rapid absorption of PA and GPAs in mice was observed, characterized by short half-lives and low bioavailability. Glycosides and hydroxyl groups significantly enhanced the absorption rate (13-OH-GPA > GPA > PA). PA and GPAs exhibited metabolic instability in liver microsomes due to Cytochrome P450 enzymes (CYPs) and uridine diphosphoglucuronosyl transferases (UGTs). Glucuronidation emerged as the primary metabolic pathway, with UGT1A7, UGT1A8, UGT1A9, and UGT1A10 demonstrating high elimination rates (30%-70%) for PA and GPAs. This rapid glucuronidation may contribute to the low bioavailability of GPAs. Despite its low bioavailability (2.69%), 13-OH-GPA showed higher kidney distribution (19.8%) compared to PA (10.0%) and GPA (7.3%), suggesting enhanced biological efficacy in kidney diseases. Modifying the C-13 hydroxyl group appears to be a promising approach to improve bioavailability. In conclusion, this study provides valuable metabolic insights for the development and optimization of marine-derived piericidins as potential drug leads for kidney disease.

Thoracolumbar spine fracture often leads to severe pain, functional impairments, and neurological deficits, for which open reduction and internal fixation can effectively restore the spinal structural stability. Open decompression and reduction with internal fixation can help relieve spinal cord compression and improve spinal function in cases of concomitant cord injury. Although spinal stability can be restored through surgery, patients often face chronic pain and functional impairments postoperatively. A postoperative rehabilitation program is critical in optimizing therapeutic outcomes, reducing complications, and minimizing the risk of secondary injuries. However, current rehabilitation methods, such as physical therapy, functional training, and pain management, are confronted with problems in clinical practice, including significant variation in efficacy, poor patient adherence, and prolonged rehabilitation period. There is an urgent need for a unified rehabilitation strategy to address these problems. To this end, the Spinal Trauma Group of the Orthopedic Physicians Branch of the Chinese Medical Association and the Spine Health Professional Committee of the Chinese Human Health Technology Promotion Association organized experts from relevant fields to formulate Evidence-based guidelines for rehabilitation treatment after internal fixation of thoracolumbar spine fracture in adults ( version 2025) by integrating evidences from clinical researches and advanced rehabilitation concepts at home and abroad. A total number of 14 recommendations concerning the rehabilitation treatment with multimodal analgesia, psychological intervention, deep vein thrombosis prevention, core muscle and extremity exercise, appropriate use of braces, early weight-bearing, device-aided rehabilitation exercise, neuroregulatory therapy, rehabilitation team were put forward, aiming to standardize the post-operative rehabilitation process following internal fixation, promote the functional recovery, and enhance patients′ quality of life.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective:To analyze the efficacy of total knee arthroplasty (TKA) with partial varus retention in the treatment of moderate knee varus.Methods:A retrospective analysis was conducted on the data of 613 osteoarthritis patients with moderate knee varus who underwent TKA at the First Affiliated Hospital of Nanjing Medical University from January 2010 to October 2019. According to whether a 2°-3° of knee varus was retained, the patients were divided into the retained varus group and the mechanical alignment group. The retained varus group included 318 cases, with 63 males and 255 females, aged 68.51±6.95 years (range, 46-86 years), and BMI of 26.99±3.66 kg/m 2 (range, 17.40-39.01 kg/m 2). Preoperative Kellgren-Lawrence (K-L) classification of knee osteoarthritis was grade III in 113 cases and grade IV in 205 cases. The mechanical alignment group included 295 cases, with 75 males and 220 females, aged 69.60±7.12 years (range, 52-87 years), and BMI of 26.95±3.94 kg/m 2 (range, 16.60-41.90 kg/m 2). Preoperative K-L classification was grade III in 102 cases and grade IV in 193 cases. Surgical duration, total blood loss, preoperative and postoperative varus angle, lower limb swelling on the fifth postoperative day, and postoperative complications were recorded. Follow-up were arranged at 3 months, 6 months, 1 year, and 5 years postoperatively. At each follow-up point, the visual analogue score (VAS) for knee pain, Hospital for Special Surgery (HSS) score, Forgotten Joint Score (FJS-12), and MOS item short-form health survey (SF-36) were assessed. Results:All 613 patients were successfully followed up, with a follow-up period of 5.25±1.02 years (range, 5.0-6.0 years). There were no statistically significant differences in gender, age, BMI, and K-L classification between the two groups ( P>0.05). The differences in postoperative varus angle, VAS scores, and HSS score were statistically significant from the preoperative values in both groups( P<0.05). The surgical duration of the retained varus group was 77.40±18.55 min, total blood loss was 920.78±407.26 ml, and lower limb swelling on the fifth postoperative day was 1.18±0.51 cm, all of which were lower than those in the mechanical alignment group: 85.31±22.15 min, 1127.14±580.08 ml, 3.22±0.52 cm, respectively, with statistically significant differences ( P<0.05). The VAS scores at postoperative day 5 and 3 months in the retained varus group were 5.08±0.72 and 2.18±1.09, respectively, which were lower than those in the mechanical alignment group: 5.80±0.81, 3.00±1.04, with statistically significant differences ( P<0.05). There were no statistically significant differences in VAS scores at 6 months, 1 year, and 5 years postoperatively between the two groups ( P>0.05). The HSS scores at 3 months and 6 months postoperatively in the retained varus group were 68.57±4.98 and 79.04±3.26, respectively, which were higher than those in the mechanical alignment group: 64.14±3.99, 77.73±4.04, with statistically significant differences ( P<0.05). There were no statistically significant differences in HSS scores at 1 year and 5 years postoperatively between the two groups ( P>0.05). The FJS-12 scores at 3 months and 6 months postoperatively in the retained varus group were 18.06±3.50 and 27.50±1.80, respectively, which were higher than those in the mechanical alignment group: 13.45±2.44, 24.23±1.59, with statistically significant differences ( P<0.05). There were no statistically significant differences in FJS-12 scores at 1 year and 5 years postoperatively between the two groups ( P>0.05). The SF-36 scores at 3 months and 6 months postoperatively in the retained varus group were 40.85±8.07 and 52.15±6.01, respectively, which were higher than those in the mechanical alignment group: 35.87±6.83, 47.28±5.38, with statistically significant differences ( P<0.05). There were no statistically significant differences in SF-36 scores at 1 year and 5 years postoperatively between the two groups ( P>0.05). The incidence of deep vein thrombosis in the lower limbs was 3.8% (12/318) in the retained varus group, which was lower than the 7.8% (23/295) in the mechanical alignment group, with a statistically significant difference ( P<0.05). Conclusion:In osteoarthritis patients with moderate knee varus undergoing TKA, retaining approximately 3° of varus can reduce surgical trauma and total blood loss, shorten surgical duration, alleviate postoperative pain and limb swelling, facilitate functional recovery, and improve patient satisfaction.
