ObjectiveMigraine is a leading neurological disorder and the fourth most common cause of years lived with disability worldwide, affecting nearly 116 million individuals. Although pharmacological treatments are available, their efficacy is often limited by side effects and variable response rates. Repetitive transcranial magnetic stimulation (rTMS) over the dorsolateral prefrontal cortex (DLPFC) offers a safe, non-invasive alternative for migraine management. However, the neurophysiological mechanisms, particularly how rTMS modulates local cortical excitability and distributed pain-related circuits, remain poorly understood. Elucidating these mechanisms is essential for optimizing treatment protocols and improving clinical outcomes. MethodsThis study employed concurrent transcranial magnetic stimulation and electroencephalography (TMS-EEG) to investigate neuroplastic and neurocircuitry mechanisms of DLPFC-rTMS in migraine. Study 1 compared 30 migraineurs and 28 healthy controls to identify abnormalities in TMS-evoked potentials (TEPs) and significant current density (SCD) within sensory-discriminative regions including the primary somatosensory cortex (S1) and posterior insula (pINS), cognitive-affective regions including the anterior insula (aINS) and midcingulate cortex (MCC), and a descending modulatory region, the periaqueductal gray (PAG). Study 2 used a single-blind, crossover, sham-controlled design in 34 healthy participants. Each participant received both active (10 Hz, 80% RMT, 1 500 pulses) and sham DLPFC-rTMS in counterbalanced order. TMS-EEG and cold pain tolerance were assessed before and after each session. ResultsIn Study 1, migraineurs showed a significantly less negative N120 amplitude compared to healthy controls (P=0.027, Cohen’s d=0.60), indicating local intracortical disinhibition. No group differences were observed for N40, P60, or P180 components. At the source level, migraineurs exhibited significantly higher SCD in the S1, pINS, aINS, and MCC (allQ<0.05), but not in the ventroposterior thalamus (vpTHAL), mediodorsal thalamus (mdTHAL), or PAG. In Study 2, active rTMS significantly reduced SCD from pre- to post-stimulation in the S1, aINS, and MCC (all Q<0.05). Sham stimulation also reduced SCD in the S1 (Q<0.05) but not in the aINS or MCC. Although no significant group-level analgesic effect was observed between active and sham conditions (P=0.107), correlation analyses revealed that greater SCD reductions in the S1 and MCC were significantly associated with higher post-rTMS pain tolerance (R=-0.487 and -0.495, both Q<0.01) and larger improvements in pain tolerance(R=-0.487 and -0.451, both Q<0.05). No such correlations were found following sham stimulation, suggesting that the behavioural relevance of neural changes is specific to active rTMS. ConclusionThis study provides novel evidence that migraineurs exhibit both local neuroplastic abnormalities (reduced N120 amplitude) and hyperactivity in key pain-processing regions (S1, pINS, aINS, MCC). A single session of DLPFC-rTMS reduced hyperactivity in the aINS, MCC, and S1. Notably, greater reductions in the S1 and MCC were associated with improved pain tolerance. These findings identify distinct cortical circuitries, particularly within the cognitive-affective pain network, that may serve as potential biomarkers for optimizing rTMS treatment in migraine and other chronic pain conditions. Future studies should validate these results in patient populations experiencing spontaneous migraine attacks and explore multi-session or accelerated rTMS protocols.

Objective:To compare the effects of 5 prone ventilation positions in patients with acute respiratory distress syndrome (ARDS) with network Meta-analysis.Methods:The randomized controlled trials on various prone ventilation positions in patients with ARDS were retrieved from Cochrane Library, EMbase, CINAHL, PubMed, Web of Science, SinoMed, CNKI, Chinese Medical Association Guideline Database, Wanfang Data, China Biology Medicine disc, VIP Information and Chinese Clinical Trial Registry from their inception to December 31, 2023. Literature screening, quality assessment and data extraction were done following the inclusion and exclusion criteria. Network Meta-analysis of outcome indicators was done using Stata 18.0.Results:A total of 19 articles, covering 1 284 patients and 5 prone ventilation positions (0°, 10°, 30°, 25° and 45°) were included. Cochrane risk assessment results showed that 15 articles were grade B and 4 articles were grade C. In direct comparisons, heterogeneity was acceptable ( I2≤50% and P≥0.1). In network analysis, the global and local consistency test result showed good consistency ( P>0.05). Network Meta-analysis result showed that the incidences of pressure injury in patients with 10°, 25°, 30° and 45° prone ventilation were significantly lower than that in patients with 0° prone ventilation, the incidence of pressure injury in patients with 25° prone ventilation was significantly lower than that in patients with 10° prone ventilation, and there were statistical differences ( P<0.05); the oxygenation index in patients with 25° prone ventilation was significantly better than that in patients with 0°, 30° and 45° prone ventilation, and there was statistical difference ( P<0.05). Conclusions:The 25° prone ventilation can both effectively improve oxygenation and maximally reduce the incidence of pressure injury in patients with ARDS.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

AIM To investigate the effects of volatile oil from Acorus tatarinowii Schott(A.tatarinowii)on neuroinflammation in a rat model of tic disorders.METHODS The SD rats were randomly divided into the blank group(8 rats)and the model group(40 rats).The rat models of tic disorders established successfully by intraperitoneal injection of iminodiapropionitrile(IDPN)were further divided into the model group,the tiapride group and the high-dose,moderate-dose and low-dose A.tatarinowii volatile oil groups,with 8 rats in each group.The 4-week intragastric treatment of respective drug was initiated the next day after the completion of modeling,and normal saline was dosed upon the blank group and the model group,during which the rats' behavioral changes were assessed by stereotyped behavior and motor behavior score every week.After the administration,the rats had their morphological changes of striatal neurons observed by Nissl staining;their levels of TGF-β,IL-10,TNF-αand IL-1β in serum and striatum detected by ELISA;their striatal protein expressions of CX3CL1 and CX3CR1 detected by Western blot and immunohistochemistry;and their striatal expressions of M1,M2 microglia marker proteins CD86,CD206,SYN and PSD-95 detected by immunofluorescence co-staining.RESULTS Compared with the model group,the A.tatarinowii volatile oil groups demonstrated improved twitch-like behavior;decreased scores of motor behavior and rigid behavior(P＜0.01);alleviated damage of Nissl bodies in neurons;increased serum and striatum levels of TGF-β and IL-10(P＜0.05,P＜0.01);decreased levels of TNF-α and IL-1β(P＜0.01);decreased striatal protein expressions of CX3CL1 and CX3CR1(P＜0.01);increased protein expressions of PSD95 and SYN(P＜0.05,P＜0.01);and decreased CD86/Iba1(P＜0.01)and increased CD206/Iba1(P＜0.01)in terms of the fluorescence intensity.CONCLUSION A.tatarinowii volatile oil contributes an anti-tic effect and improves the neuroinflammation in the brain of the rat model of tic disorders by promoting the transformation of microglia into M2 type via CX3CL1/CX3CR1 signal axis.

The conversion of abundant and low-cost biomass waste into highly efficient two-electron oxygen reduction(ORR)electrocatalyst is an important link in the degradation of pollutants in industrial wastewater through the electro-Fenton process.In this work,porous biocarbon materials doped with manganese and nitrogen(MnNBC)were prepared from corn stalk.The H2O2 selectivity of MnNBC in acidic media was up to 81% @0.6 Vvs RHE,also MnNBC exhibited a long-term stability in a 10-h uninterrupted lifetime test.The ORR activity of MnNBC could be attributed to the synergistic effect of the hierarchical porous structure,improved defect level and heteroatom doping.Moreover,MnNBC as a cathode material for the electro-Fenton system could completely degrade four kinds of common organic dye pollutants,e.g.,Rhodamine B,methyl orange,methylene blue and crystal violet(25 mg/L),respectively,within 40?60 min.The present study provided valuable insights into the transformation of corn stalk waste into efficient cathode materials for the electro-Fenton process.

Objective:To investigate the clinical efficacy of programmed Retzius-sparing robot-assisted radical prostatectomy and " Sandwich" technique of total urethral reconstruction.Methods:The clinical data of 120 consecutive patients who underwent programmed Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) by the same operator at the Cancer Hospital of the Chinese Academy of Medical Sciences from January 2023 to August 2024 were retrospectively analyzed to explore the efficacy and summarize the experience. Baseline characteristics included: mean age (67.2±7.5) years, BMI (25.3±3.1)kg/m 2, prostate volume (32.3±15.8) ml, and PSA (16.6±19.7) ng/ml (57 cases 4-10 ng/ml; 41 >10-20 ng/ml; 22 >20 ng/ml). 28 patients underwent radical prostatectomy without prostate biopsy, while 92 had biopsy-proven cancer (Gleason: 6/7/8/9/10: 18/35/17/17/5). Clinical stages were cT 1(8), cT 2(73), cT 3(39). The surgical method was programmed Retzius-sparing robot-assisted radical prostatectomy and " Sandwich" technique of total urethral reconstruction. The peritoneum was incised slightly above the Douglas pouch and denonvilliers' fascia was dissected closely along the dorsal aspect of prostate, extending to the prostatic apex. Both vas deferens were transected, and the seminal vesicles were isolated. A combination of blunt and sharp dissection was employed to expose the prostatic fascia. The bladder neck was precisely visualized and transected. The urethra was precisely dissected, exposed and divided. Complete urethral reconstruction was performed using the "Sandwich" technique of total urethral reconstruction. The operation time, intraoperative bleeding, catheter preservation time, pathological staging and positive margin rate, and recovery of urinary control immediately after postoperative catheter removal were recorded. Results:In this study, all 120 surgeries were successfully completed, with no cases converted to anterior approach radical surgery or open surgery, and no serious intraoperative complications such as post-shamus hemorrhage or ureteric/rectal injury. The median postoperative follow-up was 16.0(10.0, 20.0)months, and there were no cases of readmission for surgical complications. The average duration of surgery was (93.6±35.9) min, and the average bleeding volume was (85.3±32.1) ml. The mean duration of catheter after surgery was (7.3±1.2)d. Immediate urinary control was achieved in 98 cases when the catheter was removed, and the rate of immediate urinary control was 81.7%. Postoperative urinary control rate was 88.3% at 1 month after surgery, 94.2% at 3 month after surgery, 98.3% at 6 month after surgery. There were 70 cases with pT 2 and 50 cases with pT 3 after postoperative pathological stage. There were 18 cases (15.0%) with positive margins, including 6 cases (8.6%) with positive margins in T 2 and 12 cases (24.0%) with positive margins in T 3 stage. There were no serious complications after surgery, and urinary retention occurred in 3 cases after urinary catheter removal, and the urinary catheter was removed after 1 week. 93.3% (112/120), 90.8% (109/120), and 89.2% (107/120) of patients with PSA < 0.2 ng/ml at 1, 3, and 6 months after surgery, respectively. For postoperative erectile function, we selected patients younger than 60 years of age, who had surgery to preserve unilateral or bilateral vascular nerve bundles, and who were followed for more than 6 months. A total of 18 patients met the above conditions and were followed up for erectile function, among which 4 of the 11 patients (36.4%) who retained unilateral vascular nerve bundles regained erectile function. Among the 7 patients with bilateral vascular nerve bundle preservation, 3 patients (42.9%) regained erectile function. Conclusions:The programmed RS-RARP combined with the " Sandwich" urethral reconstruction technique is technically feasible for patients with localized prostate cancer. Recent follow-up data indicate satisfactory postoperative urinary continence and oncological control outcomes.

Health think tanks serve as a crucial intellectual support for the Healthy China strategy. The authors systematically analyzed the definitions, classifications, and operational status of health think tanks, categorizing them into five types: government-affiliated think tanks, university and research institute think tanks, social think tanks, hospital think tanks, and corporate think tanks. It was indicated that current health think tanks had significant room for improvement in both quantity and influence, particularly concerning deeper integration with policy decision-making and interdisciplinary collaboration. Although these think tanks played a unique role in supporting government decision-making, issues such as lagging institutional development, insufficient collaborative effectiveness, and difficulties in translating research findings into practice remained prominent. To enhance the ability of think tanks to serve the Healthy China strategy, this study proposed strategies including strengthening top-level design, improving participation mechanisms, optimizing management and evaluation systems, establishing data-sharing platforms, and deepening collaborative governance, with the aim of fostering the healthy development of China′s health think tanks.
