Post-stroke cognitive impairment （PSCI） is a common and severe complication in stroke patients， significantly affecting their quality of life and social function. Despite increasing research on PSCI in recent years， effective therapeutic methods remain limited. The Wnt/β-catenin signaling pathway has emerged as a critical research focus in neuroscience due to its essential role in neuroprotection， neurorepair， and cognitive recovery. Dysregulation of the Wnt/β-catenin pathway is considered one of the key mechanisms in the onset and progression of PSCI. Traditional Chinese medicine （TCM）， with its multi-component， multi-target， and synergistic properties， has shown unique advantages in modulating the Wnt/β-catenin signaling pathway， providing a potential novel approach for PSCI treatment. TCM regulates the Wnt/β-catenin pathway through various mechanisms and exerts effects such as inhibiting cell apoptosis， maintaining blood-brain barrier integrity， reducing neuroinflammation， promoting neuroplasticity， and enhancing neurorepair， thereby improving post-stroke cognitive function. This review summarized the latest research progress on the regulation of the Wnt/β-catenin signaling pathway by TCM in intervening PSCI. It analyzed the mechanisms of action of various TCM components and compound formulas within this pathway， aiming to provide a theoretical basis for innovative strategies for PSCI treatment in the future and offer new research insights and practical guidance for the application of TCM in cerebrovascular diseases.

OBJECTIVES: Managing patients with refractory head and neck cancer pain is one of the more challenging issues in clinical practice, and traditional intrathecal drug delivery also fails to provide adequate analgesia. There are currently no comprehensive and effective treatment methods. This study aims to observe the efficacy and safety of treating intractable head and neck cancer pain with morphine pump via lumbar approach to the prepontine cistern. METHODS: A total of 18 patients with intractable head and neck cancer pain treated with prepontine cistern morphine pumps were selected from the Department of Pain Management, Second Xiangya Hospital, Central South University between September 2019 and July 2023. Statistical analysis was performed on patients' preoperative and postoperative (1 week, 1 month, and 2 months after surgery), Numerical Rating Scale (NRS) scores, Self-Rating Depression Scale (SDS) scores, daily oral morphine consumption, the number of daily breakthrough pain episodes, and postoperative daily intrathecal morphine dosage. RESULTS: The NRS scores, SDS scores, daily oral morphine consumption, and the number of daily breakthrough pain episodes of patients at each time point after surgery were significantly lower than before surgery (all P<0.05). With the gradual increase in the dosage of intrathecal morphine, the daily oral morphine consumption of patients at each postoperative time point was significantly reduced compared to preoperative levels (all P<0.05). The complications related to the operation were mild, including nausea in 5 cases (31.3%), headache in 2 cases (12.5%); hypotension, urine retention, hypersomnia and constipation in 1 case (6.3% each), and no serious adverse events occurred. All improved and were discharged after symptomatic treatment. CONCLUSIONS The implantation of prepontine cistern morphine pump effectively controls intractable head and neck cancer pain, demonstrating characteristics of minimal invasiveness, mild side effects, and low medication dosage under the premise of standardized procedures.

The research on medical image segmentation is of great significance in advancing efficient and accurate automated image processing techniques.To address the problem of inaccurate segmentation results caused by significant variations in organ tissue shapes and blurred boundaries present in medical images,a novel network named MFMANet is proposed.Built upon a"U"-shaped architecture,the network integrates multi-scale information fusion modules and multi-attention modules.Specifically,multi-scale information modules capture multi-scale information in the shallow layers of the network to bridge the semantic gap between encoder and decoder features,thereby enhancing the network's ability to handle large variations in organ sizes.Regarding the issue of blurred boundaries,multi-attention mechanism utilizes Swin Transformer as the deep encoder-decoder network,employing channel and spatial attention instead of traditional skip connections to achieve finer feature extraction.Experimental results on the ACDC and Synapse public datasets show that the proposed method achieves improvements of 1.51%and 1.29%in Dice similarity coefficient as compared with MTUNet,fully demonstrating its effectiveness in enhancing segmentation network accuracy.

Spinal surgical site infection (SSI), especially deep SSI after internal fixation is difficult in treatment, with long course of disease and poor prognosis. At present, there are many controversies in the diagnosis and treatment of spinal SSI, with unsatisfactory overall efficacy of its diagnosis and treatment. Besides, no diagnosis and treatment guideline based on evidence-based medicine has been in existence. To this end, the Spinal Infection Group of the Orthopedic Branch of the Chinese Medical Doctor Association and the Spinal Infection Group of the Spinal Surgery Branch of the Chinese Rehabilitation Medicine Association jointly organized relevant experts to formulate Evidence-based clinical guideline for the diagnosis and treatment of surgical site infection in spinal trauma ( version 2024) based on an evidence-based approach. A total of 10 recommendations were proposed on the diagnosis and treatment of spinal SSI, so as to provide a clinical reference for the diagnosis and treatment of spinal SSI.

Objective:To compare and analyze the differences in the measurement of intra-abdominal pressure in different positions of critically ill patients treated with extracorporeal membrane oxygenation (ECMO) combined with prone position integration, with a view to finding a more optimal intra-abdominal pressure monitoring strategy, which can provide a theoretical basis for clinical diagnosis and treatment.Methods:Forty critically ill patients who underwent ECMO combined with prone position integrated treatment in the department of Intensive Care Medicine of the First Affiliated Hospital of Guangxi Medical University from January 2020 to June 2023 were selected by convenience sampling method using an own-control trial. The differences in intra-abdominal pressure between supine position with head elevated at 0°, 15°and 30°and prone position with head high and foot low slopes at 0°, 15°and 30°were compared and analyzed. Heart rate, respiration, mean arterial pressure and oxygen saturation were also compared in patients in different positions.Results:There were 29 males and 11 females in 40 patients with the age of (62.58 ± 17.99) years.The intra-abdominal pressure in supine position with head elevated at 30° was (12.45 ± 3.43) mmHg(1 mmHg=0.133 kPa), which was higher than that of 0° and 15° of (9.38 ± 2.52) and (10.70 ± 2.95) mmHg, and the differences were statistically significant ( t=4.56, 2.45, both P<0.05);the difference in intra-abdominal pressure between 0° and 15° was not statistically significant ( P>0.05); the intra-abdominal pressure in prone position with head-high-foot-low slope of 30° was (12.92 ± 4.19) mmHg, which was higher than that of 0°and 15°of (9.67 ± 2.80), and (11.01 ± 3.10) mmHg, and the differences were statistically significant ( t=4.08, 2.32, both P<0.05); the difference in intra-abdominal pressure between 0° and 15° was not statistically significant ( P>0.05).The differences in intra-abdominal pressure between groups of supine bed head elevation 0°, 15°, 30°and prone position with head high and foot low slopes 0°, 15°, 30°were not statistically significant (all P>0.05). The differences in heart rate, respiration, mean arterial pressure and oxygen saturation in the supine position with head elevated at 0°, 15°and 30° were not statistically significant when compared within groups (all P>0.05); the differences in heart rate, respiration, mean arterial pressure and oxygen saturation in the prone position with head elevated with feet and feet on low slopes at 0°, 15°and 30°were not statistically significant when compared within groups (all P>0.05); and the differences in supine position with head elevated at 0°, 15°, 30°and prone head-height-foot-low slope 0°, 15°, 30°of heart rate, respiration, mean arterial pressure were not statistically significant (all P>0.05); supine bed head elevation 0°, 15°, 30°and prone head-height-foot-low slope 0°, 15°, 30°of oxygen saturation between the groups, the differences were statistically significant ( Z=6.85, 6.82, 6.68, all P<0.05). Conclusions:Intra-abdominal pressure can be measured in the 15° prone position in critically ill patients treated with ECMO combined with prone position integration; the different positions have little effect on vital signs, but the prone position significantly improves oxygen saturation.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

OBJECTIVE: To investigate the effectiveness of preemptive analgesia with imrecoxib on analgesia after anterior cruciate ligament (ACL) reconstruction. METHODS: A total of 160 patients with ACL injuries who met the selection criteria and were admitted between November 2020 and August 2021 were selected and divided into 4 groups according to the random number table method (n=40). Group A began to take imrecoxib 3 days before operation (100 mg/time, 2 times/day); group B began to take imrecoxib 1 day before operation (100 mg/time, 2 times/day); group C took 200 mg of imrecoxib 2 hours before operation (5 mL of water); and group D did not take any analgesic drugs before operation. There was no significant difference in gender, age, body mass index, constituent ratio of meniscal injuries with preoperative MRI grade 3, constituent ratio of cartilage injury Outerbridge grade 3, and visual analogue scale (VAS) score at the time of injury and at rest among 4 groups (P>0.05). The operation time, hospitalization stay, constituent ratio of perioperative American Society of Anesthesiologists (ASA) grade 1, postoperative opioid dosage, and complications were recorded. The VAS scores were used to evaluate the degree of knee joint pain, including resting VAS scores before operation and at 6, 24, 48 hours, and 1, 3, 6, and 12 months after operation, and walking, knee flexion, and night VAS scores at 1, 3, 6, and 12 months after operation. The knee injury and osteoarthritis score (KOOS) was used to evaluate postoperative quality of life and knee-related symptoms of patients, mainly including pain, symptoms, daily activities, sports and entertainment functions, knee-related quality of life (QOL); and the Lysholm score was used to evaluate knee joint function. RESULTS: All patients were followed up 1 year. There was no significant difference in operation time, hospitalization time, or constituent ratio of perioperative ASA grade 1 among 4 groups (P>0.05); the dosage of opioids in groups A-C was significantly less than that in group D (P<0.05). Except for 1 case of postoperative fever in group B, no complications such as joint infection, deep vein thrombosis of the lower extremities, or knee joint instability occurred in each group. The resting VAS scores of groups A-C at 6 and 24 hours after operation were lower than those of group D, and the score of group A at 6 hours after operation was lower than those of group C, and the differences were significant (P<0.05). At 1 month after operation, the knee flexion VAS scores of groups A-C were lower than those of group D, the walking VAS scores of groups A and B were lower than those of groups C and D, the differences were significant (P<0.05). At 1 month after operation, the KOOS pain scores in groups A-C were higher than those in group D, there was significant difference between groups A, B and group D (P<0.05); the KOOS QOL scores in groups A-C were higher than that in group D, all showing significant differences (P<0.05), but there was no significant difference between groups A-C (P>0.05). There was no significant difference in VAS scores and KOOS scores between the groups at other time points (P>0.05). And there was no significant difference in Lysholm scores between the groups at 1, 3, 6, and 12 months after operation (P>0.05). CONCLUSION Compared with the traditional analgesic scheme, applying the concept of preemptive analgesia with imrecoxib to manage the perioperative pain of ACL reconstruction can effectively reduce the early postoperative pain, reduce the dosage of opioids, and promote the early recovery of limb function.
