Therefore，building on the series of salons on the ED-focused dominant diseases of traditional Chinese medicine，this paper provides standardized guidance for clinical practice of traditional Chinese medicine in ED management，effectively contributing to the high-quality development of traditional Chinese medicine. It serves as a valuable reference for national scientific and technological strategic layout， research and development decision-making in new drugs of traditional Chinese medicine，research topic planning，and clinical guideline formulation.

The occurrence of diabetes mellitus （DM） is closely related to insulin resistance and islet β cell dysfunction. Modern studies have found that macrophages are widely present in the liver，fat，skeletal muscle，islets， and other tissues and organs. Macrophage M1/M2 polarization plays an important role in the occurrence and development of diabetes mellitus and its related complications by intervening in inflammatory response，improving insulin resistance，and promoting tissue repair. Most of the traditional Chinese medicines that regulate the activation and polarization of macrophages are Qi-replenishing and Yin-nourishing，heat-clearing， and detoxicating medicinal，which are consistent with the etiology and pathogenesis of diabetes and its related complications. Therefore，by summarizing the mechanisms between macrophage activation，polarization， and insulin resistance in various tissues，this paper reviewed traditional Chinese medicine and its effective components and compounds in improving diabetes mellitus and its related complications through multi-channel regulation of macrophage polarization and regulation of M1/M2 ratio，providing references for the future treatment of DM and its related complications with traditional Chinese medicine.

Glycoprotein non-metastatic melanoma protein B (GPNMB) is a transmembrane glycoprotein that plays an important role in various physiological and pathological processes. In recent years, its role in lung diseases has gradually attracted attention. Studies have found that GPNMB is abnormally expressed in lung diseases and is involved in regulating pathological processes such as inflammatory responses, fibrosis, and tumorigenesis. This article systematically reviews the research progress of GPNMB in common lung diseases such as chronic obstructive pulmonary disease (COPD), pulmonary fibrosis, and lung cancer, and explores its potential as a therapeutic target, providing new insights for the diagnosis and treatment of lung diseases in the future.

Objective To investigate the status of feeding intolerance in patients with enteral nutrition after lung transplantation and analyze its influencing factors,to provide a reference for formulating a reasonable enteral nutrition plan and improving patients'nutritional status.Methods Convenient sampling method was used to retrospectively collect the clinical data of 115 patients who received enteral nutrition support after lung transplantation and were hospitalized in the ICU of a tertiary hospital in Guangdong Province from August 2022 to November 2023.According to the occurrence of feeding intolerance during ICU hospitalization,the patients were divided into a feeding tolerance group and a feeding intolerance group.Univariate and logistic regression analysis were used to analyze the influencing factors of feeding intolerance patients with enteral nutrition after lung transplantation.Results Within 7 days of initiating enteral nutrition,a total of 63 patients developed feeding intolerance,with an incidence of 54.78％.Among them,the incidence of feeding intolerance was relatively high within 1 to 3 days after initiating enteral feeding.The clinical manifestations of feeding intolerance were diarrhea,bloating,gastric retention,vomiting/regurgitation,among which the diarrhea was the highest incidence(87.30％).Logi-stic regression analysis showed that intraoperative net balance volume(OR=0.999),intraoperative blood transfusion(OR=1.001)volume and diabetes history(OR=0.170)were independent influencing factors for feeding intolerance in patients with enteral nutrition after lung transplantation(P＜0.05).Conclusion There was a high incidence of feed-ing intolerance in patients with enteral nutrition after lung transplantation.Patients undergoing lung transplantation who have a high net intraoperative fluid balance,receive a low volume of intraoperative blood transfusions,and have a history of diabetes are at a lower risk of developing feeding intolerance when receiving postoperative enteral nutrition.When starting enteral nutrition,medical staff should dynamically evaluate the risk factors of feeding intolerance,screen high-risk patients as early as possible,and formulate reasonable enteral nutrition programs to improve the nutritional status of patients and promote their rehabilitation.

Objective:To investigate how age and nail-tract volumetric bone mineral density (vBMD) are associated with postoperative mechanical performance of proximal femoral nail anti-rotation (PFNA-Ⅱ) fixation for geriatric intertrochanteric fractures using a finite-element analysis.Methods:Fifteen elderly patients with intertrochanteric fracture of the femur were selected for this study. They were 11 females and 4 males and divided into 5 groups based on their ages ( n=3): 55-year-old, 65-year-old, 75-year-old, 85-year-old, and 95-year-old groups. After three-dimensional models of the proximal femur were constructed using the preoperative CT data of their healthy contralateral hip, 31-A1.2 fractures of the AO/OTA type were created and PFNA-Ⅱ fixations simulated. Two loading schemes were created: graded quasi-static axial loads (700 N, 1,400 N, 2,100 N, and 2,800 N) were applied to compute equivalent plastic strain volumes in the femoral head region; displacement-controlled loading was applied to failure to derive load-displacement curves for stiffness and the maximum failure load. Nail-tract vBMD and regional hip vBMDs were measured by quantitative CT. Pearson correlation analysis was conducted to investigate the associations of age and nail-tract vBMD with the aforementioned mechanical indicators. Results:Under the same load, compared with the 55-year-old, 65-year-old, and 75-year-old groups, the plastic strain unit volumes of the fracture models in the 85-year-old and 95-year-old groups increased significantly. Under a load of 700 N, no plastic strain was observed in the fracture models in the 55-year-old, 65-year-old, and 75-year-old groups, while an average plastic strain of approximately 50 mm 3 was observed in the fracture models in the 85-year-old group. Under a load of 2,800 N, the high strain areas in the fracture models in the 85-year-old and 95-year-old groups were mainly concentrated at the tip of the head nail and the junction between the head nail and the main nail. Load-displacement curves showed a marked reduction in the failure load in patients aged ≥85 years. Under loads of 1,400 N, 2,100 N, and 2,800 N, there was a strong association between the nail-tract vBMD and the volume of the plastic strain unit ( r=-0.82, -0.88, -0.89, respectively), which was stronger than those for total-hip vBMD. Conclusions:Finite-element analysis indicates that age and nail-tract vBMD are closely related to local plastic strain and overall stiffness of the proximal femur after PFNA-Ⅱ fixation for the geriatric intertrochanteric fractures. Patients aged ≥85 years old are more prone to plastic yielding, which compromises fixation stability.

Cardiac arrest is a major health event that poses a major threat to human life and health.Post-cardiac arrest brain injury is the main adverse prognostic factor and cause of death in patients who experience cardiac arrest.Currently,the therapeutic methods and effects are limited.In recent years,with the in-depth research on microbiota-gut-brain communication,it has been found that intestinal microbiota and their metabolites may play a role in the regulation of neuroinflammation in post-cardiac arrest brain injury.Short-chain fatty acids are the key substances in microbiota-gut-brain communication,and the mechanism involves immune,endocrine and neuroregulatory pathways.Supplementation of short-chain fatty acid-producing bacteria or short-chain fatty acids can improve intestinal flora disorder and reduce neuroinflammation after cardiopulmonary resuscitation.As a key mediator in microbial-gut-brain communication,short-chain fatty acids have great potential for the treatment of brain injury after cardiac arrest.This review explores the role and regulatory mechanism of microbiota-gut-brain communication in the neuroinflammation of brain injury after cardiopulmonary resuscitation through immune,endocrine and neuro-regulatory pathways,providing a new idea for the treatment of post-cardiac arrest brain injury.

Objective:To explore the efficacy and safety of the Da Vinci robotic single-port-plus-one technique in common urological surgeries in children.Methods:The data of 59 children who underwent robot-assisted single-port-plus-one laparoscopic surgery from May 2022 to November 2023 in Fuzhou University Affiliated Provincial Hospital were retrospectively analyzed. There were 44 males and 15 females, aged 36 (6, 108)months. Among them, 27 cases had ureteropelvic junction obstruction, with a preoperative anterior-posterior diameter of the renal pelvis of (31.83±6.59) mm. The American Society of Fetal Urology (SFU) grading system revealed grade Ⅲ in 8 sides and grade Ⅳ in 19 sides. Bilateral renal function showed a difference of 13.50% (7.18%, 31.06%). Additionally, 17 cases presented with vesicoureteral reflux. Preoperative voiding cystourethrogram (VCUG) indicated reflux grades Ⅲ, Ⅳ, and Ⅴ in 8, 14, and 4 sides, respectively, with a difference in bilateral renal function of 18.58% (6.04%, 28.30%). Ten cases had obstructive megaureter, with a preoperative renal pelvis diameter of (22.17±7.64)mm and a maximum ureteral diameter of (19.51±3.71)mm. The preoperative bilateral renal function difference was 18.02% (5.23%, 49.42%).Five cases involved duplicated kidney and ureter. Magnetic resonance urography (MRU) confirmed unilateral duplicated kidneys with associated dilatation of the upper renal pelvis and calyces, hydroureter, thin renal cortex in all 5 patients. Among them, 2 cases had ectopic ureteral opening and 1 case had terminal ureteral cyst. Patients with ureteropelvic junction stenosis underwent pyeloplasty, those with vesicoureteral reflux and obstructive megaureter underwent ureteral reimplantation, and patients with duplicated ureters underwent nephrectomy. The Da Vinci robotic surgical system was employed for all procedures. The port placement technique involved a 2-3 cm incision around the navel to insert a single-port four-channel device, followed by the placement of an additional 8 mm operating channel in the left or right abdomen under direct visualization based on the surgical site. Preoperative and postoperative parameters were compared.Results:All operations were successfully completed without conversion to open or laparoscopic surgery. The operation time of the ureteropelvic junction obstruction children was (141.52±22.93) min. The postoperative renal pelvis diameter and bilateral renal function difference were (12.54±4.05) mm and 5.60%(2.14%, 14.48%), respectively, both of which showed significant improvement compared to preoperative levels ( P<0.01). Postoperative hydronephrosis grades were as follows: 13 sides with grade Ⅰ, 13 sides with grade Ⅱ, and 1 side with grade Ⅲ. The operation time of vesicoureteral reflux children was (125.00±11.75) min in the unilateral group and (153.22±14.39) min in the bilateral group. Postoperatively, 2 sides demonstrated reflux grade Ⅰ, 1 side grade Ⅱ, and 1 side grade Ⅲ, indicating improvement compared to preoperative levels. Bilateral renal function difference post-surgery was 13.34% (1.85%, 20.54%), which was more balanced than preoperatively ( P=0.011). Postoperative renal pelvis anterior-posterior diameter and maximum ureteral diameter were reduced to (10.31±3.86) mm and (6.62±2.44) mm, respectively, which were significantly smaller than preoperative measurements ( P<0.01). The bilateral renal function difference post-surgery was 12.04% (4.85%, 47.53%), showing improvement, though not statistically significant ( P=0.508). The operation time of the repeated nephrectomy children was (140.00±12.75) min. No recurrence of preoperative symptoms was noted, and renal cortical function remained generally normal during follow-up. In this study, only 3 cases of obstructive megaureter developed febrile urinary tract infection within 1 month after surgery, and no complications were observed in the remaining cases. Conclusions:This study preliminarily confirmed that the Da Vinci robotic single-port-plus one-port technology can be used in the treatment of common diseases of the urinary system in children. The patients' symptoms were significantly relieved after surgery, and the indicators of hydronephrosis improved compared with those before surgery. The incidence of postoperative complications was low, and aesthetic outcomes of postoperative scars were enhanced. Further studies are needed to assess its long-term efficacy.

Objective:To compare the dose-response effects of single-fraction ultra-high dose rate (FLASH) and conventional dose rate (CONV) whole abdominal irradiation (WAI) with X-rays on acute radiation-induced intestinal injury in mice, in order to identify optimal dose parameters and potential mechanisms.Methods:A total of 186 male C57BL/6J mice were randomly assigned to a non-irradiation group ( n=6), FLASH irradiation groups ( n=90), and CONV irradiation groups ( n=90). Acute radiation-induced intestinal injury models were established using single-fraction WAI with 11, 12, 13, 14, and 15 Gy X-rays (200 Gy/s for FLASH and 4 Gy/min for CONV). Changes in body weight, stool characteristics, and disease activity index (DAI) scores were assessed at 9 d post-irradiation. At 7 d post-irradiation at 11, 12, and 13 Gy, the intestines were collected for macroscopic examination and length measurement. The small intestine was selected for HE staining and quantitative analysis of intestinal crypt number and mucosal epithelial thickness. The survival of mice was assessed at 15 d post-WAI across all dose groups. Results:After single-fraction WAI at 11, 12, and 13 Gy, the body weight was higher in the FLASH group than that in the CONV group ( t=10.17, 12.65, 10.16, P<0.05). The DAI scores for the FLASH group were 1.00±1.10, 3.17±0.75, and 2.83±1.17, respectively, which were lower than those of the CONV group (4.33±0.52, 7.00±0.00, 8.60±0.55; t=8.70, 11.71, 14.99, P<0.05). However, after WAI at 14 Gy and 15 Gy, there were no significant differences in body weight and DAI between the FLASH group and the CONV group ( P>0.05). At 7 d after single-fraction WAI at 11, 12, and 13 Gy, mice in the FLASH group exhibited less intestinal congestion, edema, and shortening compared with the CONV group. The difference between the FLASH and CONV groups were statistically significant in small intestine length at 11 and 13 Gy ( t=4.42, 3.78, P<0.05), and in colorectal length at 11 and 12 Gy ( t=3.97, 3.12, P<0.05). Small intestine HE staining revealed superior preservation of intestinal architecture in the FLASH group compared with the CONV group, characterized by longer villi, increased crypt numbers, thicker mucosal epithelium, and enhanced structural integrity. The differences in crypt number and mucosal epithelial thickness were statistically significant ( tcrypt=13.10, 23.80, 11.90; tmucosal=5.75, 2.64, 7.74; P<0.05). At 15 d post-irradiation, the survival rate in the 15 Gy FLASH group was higher than that in the CONV group (50% vs. 10%, χ2=5.39, P<0.05), with a median survival extension of 6 d ( HR=0.340, 95% CI: 0.115 4-0.999 9). No significant survival differences were observed between the FLASH group and the CONV group at 11, 12, 13, and 14 Gy ( P>0.05). Conclusions:FLASH irradiation significantly alleviated acute radiation-induced intestinal injury from medium single-fraction WAI with 11, 12, and 13 Gy X-rays compared with CONV irradiation, and showed potential to improve mouse survival after single-fraction WAI at 15 Gy. This effect is likely associated with the preservation of intestinal crypts and exhibits a dose-dependent relationship.

Background:Acute pancreatitis(AP)is a common clinical gastrointestinal emergency with a high mortality rate.Intestinal dysfunction is one of the common complications of AP and can aggravate the disease condition.Therefore,early and accurate assessment of the disease severity and intestinal dysfunction of AP is of great significance for improving the prognosis of patients.Aims:To investigate the correlation of early serum levels of interleukin-1β(IL-1β),C-reactive protein(CRP),endotoxin(ET),D-lactic acid(D-LA),and diamine oxidase(DAO)with disease severity and intestinal dysfunction in AP patients.Methods:A total of 52 AP patients admitted to the Second Affiliated Hospital of Baotou Medical College from September 2023 to September 2024 were enrolled,and 10 healthy individuals recruited during the same period were served as the control group.AP patients were classified into mild acute pancreatitis(MAP),moderately severe acute pancreatitis(MSAP)and severe acute pancreatitis(SAP)groups according to the severity of the disease.Intestinal function was evaluated using the acute gastrointestinal injury(AGI)grading system.ELISA was used to detect the early serum levels of IL-1β,CRP,ET,D-LA,and DAO,and the correlation of these indicators with the severity of AP and AGI grade were analyzed by Spearman correlation coefficient.Results:Serum levels of IL-1β,CRP,ET,D-LA,and DAO in the MAP,MSAP,and SAP groups were significantly higher than those in the control group(all P<0.05);serum levels of IL-1β,CRP,ET,D-LA,and DAO in the MSAP group were significantly higher than those in the MAP group(all P<0.05);serum levels of IL-1β,CRP,ET,D-LA,and DAO in the SAP group were significantly higher than those in the MAP and MSAP groups(all P<0.05).Compared with AGI grade 0-Ⅰ subjects,serum levels of IL-1β,CRP,ET,D-LA,and DAO in patients with AGI grade Ⅱ,Ⅲ and Ⅳ were significantly increased(all P<0.05).Compared with AGI grade Ⅱ patients,serum D-LA level in patients with AGI grade Ⅲ was significantly increased(P<0.05).Compared with AGI grade Ⅲ patients,serum D-LA level in patients with AGI grade Ⅳ was significantly increased(P<0.05).Serum levels of IL-1β,CRP,ET,D-LA,and DAO were positively correlated with the severity of AP and AGI grade(all P<0.05).Conclusions:Early serum levels of IL-1β,CRP,ET,D-LA,and DAO in AP patients are significantly increased and closely related to the disease severity and intestinal dysfunction.

Autism spectrum disorder(ASD),characterized by unknown etiology and high heterogeneity,ne-cessitates precise diagnostic and intervention strategies.Neuroimaging techniques have shown great promise in un-covering the neural mechanisms of ASD,providing a foundation for aided diagnosis and transcranial magnetic stim-ulation(TMS)interventions.This review highlights that integrating multimodal neuroimaging and developing indi-vidualized indices with developmental specificity can significantly improve the accuracy of ASD diagnosis and clas-sification.Furthermore,TMS interventions guided by functional connectivity derived from functional magnetic reso-nance imaging(fMRI)offer a personalized approach to ASD treatment.
