ObjectiveTo investigate the clinical effects and safety of Shuhe Granules （舒和颗粒） in patients with rheumatoid arthritis （RA） comorbid with insomnia. MethodsA single-arm prospective exploratory design was adopted. Thirty RA patients comorbid with insomnia and diagnosed with the traditional Chinese medicine （TCM） syndrome of kidney-heart deficiency and qi-blood disharmony were enrolled. On the basis of maintaining their original RA treatment regimens， all patients received oral Shuhe Granules， one dose per day， for 12 consecutive weeks. The outcomes were assessed before treatment and at weeks 4， 8， and 12 after treatment. Sleep and related psychosomatic function were evaluated using the insomnia severity index （ISI）， Pittsburgh sleep quality index （PSQI）， fatigue severity scale （FSS）， patient health questionnaire-9 （PHQ-9）， generalized anxiety disorder-7 （GAD-7）， and Montreal cognitive assessment （MoCA） scores. RA-related assessments included the 28-joint disease activity score based on C-reactive protein （DAS28-CRP）， pain visual analog scale （VAS）， tender joint count （TJC28）， swollen joint count （SJC28）， morning stiffness duration， and health assessment questionnaire （HAQ） score. Laboratory parameters included erythrocyte sedimentation rate （ESR）， serum C-reactive protein （CRP）， anti-cyclic citrullinated peptide antibody （anti-CCP）， and rheumatoid factor （RF） levels. A literature-based historical control group was established through literature retrieval and meta-analysis. The ISI， PSQI， DAS28-CRP， and pain VAS scores were compared between the treatment group in the present study and the historical control group. Safety assessments were also performed. ResultsCompared with baseline before treatment， ISI and PSQI scores decreased at weeks 4， 8， and 12， while MoCA scores increased at weeks 4， 8， and 12. FSS scores decreased at weeks 4 and 12. At weeks 8 and 12， GAD-7 scores， DAS28-CRP scores， duration of morning stiffness， TJC28， and SJC28 were reduced. At week 12， PHQ-9， pain VAS， and HAQ scores significantly decreased （P＜0.05）. FSS and DAS28-CRP scores at week 12 were lower than those at week 4， and CRP levels at week 8 were lower than those at week 4 （P＜0.05）. Compared with the historical control group， the treatment group showed superior improvement in ISI and PSQI scores （P＜0.001）； however， no statistically significant differences were observed between the two groups in DAS28-CRP or pain VAS scores （P＞0.05）. No serious adverse events occurred during the study， and the 4 reported mild adverse events were all considered unrelated to the study medication. ConclusionShuhe Granules significantly improve sleep quality， fatigue， emotional status， cognitive function， RA-related symptoms， and joint function in patients with RA comorbid insomnia， with good safety and tolerability.

Loss-of-function variants in CSDE1 have been strongly linked to neuropsychiatric disorders, yet the precise role of CSDE1 in neurogenesis remains elusive. In this study, we demonstrate that knockout of Csde1 during cortical development in mice results in impaired neural progenitor proliferation, leading to abnormal cortical lamination and embryonic lethality. Transcriptomic analysis revealed that Csde1 upregulates the transcription of genes involved in the cell cycle network. Applying a dual thymidine-labelling approach, we further revealed prolonged cell cycle durations of neuronal progenitors in Csde1-knockout mice, with a notable extension of the G1 phase. Intersection with CLIP-seq data demonstrated that Csde1 binds to the 3' untranslated region (UTR) of mRNA transcripts encoding cell cycle genes. Particularly, we uncovered that Csde1 directly binds to the 3' UTR of mRNA transcripts encoding Cdk6, a pivotal gene in regulating the transition from the G1 to S phases of the cell cycle, thereby maintaining its stability. Collectively, this study elucidates Csde1 as a novel regulator of Cdk6, sheds new light on its critical roles in orchestrating brain development, and underscores how mutations in Csde1 may contribute to the pathogenesis of neuropsychiatric disorders.

BACKGROUND:The biomechanical analysis of scoliosis cases is limited,with only independent analysis focusing on the spine or lower limbs,thus lacking a comprehensive evaluation of the multidimensional body.As a result,it becomes challenging to reflect the movement relationship between the trunk and lower limbs during daily activities,which hinders comprehensive clinical treatment guidance. OBJECTIVE:To explore the relationship between different segments of the spine and the kinematics/kinetics of the lower limbs during gait activities by measuring spinal kinematics in scoliosis patients,to provide a comprehensive and multi-level assessment of the biomechanical differences between scoliosis patients and the normal population,consequently offering evidence-based guidance for the prevention and treatment of scoliosis. METHODS:A cross-sectional study was conducted from July 2020 to June 2021 at the Rehabilitation Hospital Affiliated to Fujian University of Traditional Chinese Medicine in Fuzhou University City.A total of 28 scoliosis patients and 28 normal individuals in the same age group were included.Three-dimensional motion capture system was used to capture gait kinematic data at a sampling frequency of 100 Hz.Two force plates(AMTI 400600,sampling frequency 1 500 Hz)were embedded in a 10-meter-long 2.4-meter-wide level ground walkway(with an effective data collection length of 4 m)to collect kinetic data.The differences in spatial-temporal parameters,kinematics,and kinetics of gait between the two groups were compared.Immediately after inclusion,all subjects underwent full spinal X-ray measurements to compare the differences between the scoliosis and normal groups. RESULTS AND CONCLUSION:(1)Patients with scoliosis exhibited reduced relative rotational range of motion between the shoulder and trunk,as well as between the thorax and pelvis,compared to the normal group(P<0.05).However,the rotational range of motion in the pelvis was larger in patients with scoliosis compared to the normal group(P<0.05).(2)Patients with scoliosis showed decreased range of motion in the hip and knee joints,as well as reduced peak torque in hip joint flexion and extension,and lower peak values of ground reaction forces in the concave and convex directions,in comparison to the normal group(P<0.05).(3)Patients with scoliosis demonstrated greater asymmetry indices in knee joint range of motion,relative rotational range of motion between the shoulder and trunk,and between the thorax and pelvis,when compared to the normal group(P<0.05).(4)These findings illustrate a rigid movement pattern among the shoulder,thorax,and pelvis in patients with scoliosis during level walking.There is a reduction in range of motion in the hip and knee joints,as well as decreased peak torque values in hip joint flexion and extension,and ground reaction forces in the concave and convex directions.These characteristics can serve as foundational elements for assessing rehabilitation and developing treatment plans.

Objective To assess the clinical feasibility of a self-developed augmented reality(AR)system in surgeries for cerebral arteriovenous malformation(AVM),dural arteriovenous fistula(DAVF),moyamoya,and internal carotid artery stenosis.This system integrates preoperative vascular imaging(CTA,MRA,DSA)with intraoperative real-time visualization through high-precision patient-image registration and virtual-real integration technology.Methods A retrospective analysis was conducted on 6 patients(1 cerebral AVM,1 DAVF,3 moyamoya and 1 internal carotid artery stenosis)collected between March 2023 and April 2024.AR with three-dimensional reconstruction was used for preoperative precise localization and intraoperative navigation guidance.Clinical feasibility was evaluated and analyzed using an intraoperative self-controlled method.Results All 6 patients with diverse etiologies successfully underwent preoperative precise localization and intraoperative navigation guidance under AR three-dimensional reconstruction modeling.This technology achieved visualization of intracranial arteriovenous structures and precise lesion locations,providing surgeons with a visual reference for accurate planning of the surgical approach and operative field.Conclusion The application of AR with three-dimensional reconstruction is safe and feasible in neurosurgical procedures for cerebrovascular diseases.It demonstrates satisfactory effectiveness in preoperative localization and intraoperative navigation guidance.

Objective To compare the radiotherapy treatment accuracy between 4D-CT and DIBH follow-ing liver SBRT,and to illustrate the relevant factors.Methods A retrospective analysis was conducted on the clinical data of 28 liver cancer patients who underwent SBRT from November 2020 to July 2024,all of whom exhib-ited and localizedmorphological changes on magnetic resonance imaging(MRI).Among them,8 patients used DIBH,and 17 patients used 4D-CT.The areas of localized MRI-morphologic alterations(MMA)were delineated on post-therapeutic MRI.Different isodose structures were generated on the planning CT,and after performing de-formation registration based on the liver's region of interest(ROI),the most suitable isodose structure and MMA contours were compared to obtain quantitative accuracy indices.Correlations between factors such as GTV,PTV,liver volume,and volume changes,and the accuracy indices were analyzed.Results The DSC accuracy for the DIBH group was(0.66±0.17),range 0.32～0.90,while the DSC accuracy for the 4D CT group was(0.69±0.10),range 0.49～0.80.T-test analysis showed no significant statistical differences in accuracy indices between the DIBH and 4D CT groups(P<0.05).Correlation analysis revealed that,in both groups,distance-based indices(HD,MDA,3D-CoMD)were more strongly correlated with accuracy indices than conformality indices(DSC,CIMI).Conclusion There was no significant difference in treatment accuracy between the DIBH and 4D-CT groups,although the maximum accuracy in the DIBH group was higher than that in the 4D-CT group.This method can serve as an bench-markingtool for evaluating the accuracy of liver SBRT.It is recommended to prioritize the use of conformality indices,DSC and CIMI,when assessing the treatment accuracy of liver cancer SBRT using this approach.

Objective:To compare the efficacy and safety of flow diverter (FD) implantation versus stent-assisted coil embolization (SACE) in unruptured saccular aneurysms located at distal segments of the Willis circle.Methods:A retrospective study was performed; 119 patients with unruptured saccular aneurysms located at distal segments of the Willis circle who received FD implantation or SACE in Department of Neurosurgery, Guangdong Provincial People's Hospital, Southern Medical University and Department of Cerebrovascular Surgery, Neurosurgery Center, Southern Medical University from January 2018 to May 2025 were selected. According to different surgical methods, they were divided into a FD group ( n=60) and a SACE group ( n=59). These patients were subjected to propensity score matching (PSM) using 1:1 nearest neighbor matching method to eliminate confounding factors such as gender, age, aneurysm location, and aneurysm diameter (maximum diameter); and then, differences in neurological functional prognosis (good prognosis: modified Rankin scale scores of 0-2), complete aneurysm occlusion rate (O'Kelly-Marotta grade D or Raymond occlusion classification class I), and overall (perioperative and follow-up) complications were compared between the two groups. Results:After PSM, there were 43 patients in both FD group and SACE group. No significant difference was found in clinical and imaging follow-ups (12[6, 19] months vs. 10[6, 15] months, 10[5, 19] months vs. 9[2, 15] months) between the FD group and SACE group ( P>0.05). At the last imaging follow-up, the complete aneurysm occlusion rate in the FD group (65.1%[28/43]) was significantly lower than that in the SACE group (76.7%[33/43], P<0.05). At the last clinical follow-up, no significant difference was noted in good prognosis rate (95.3%[41/43] vs. 97.7%[42/43]) and overall complication rate (30.2%[13/43] vs. 18.6%[8/43]) between the FD group and SACE group ( P>0.05). Conclusion:Both FD implantation and SACE are safe and effective for unruptured saccular aneurysms located at distal segments of the Willis circle; the complete aneurysm occlusion rate within 1 year of FD implantation is relatively low.

Objective To observe the differences in dynamic stability and kinematic/kinetic characteristics of the lower limbs between patients with knee osteoarthritis(KOA)and healthy individuals at the begining stage of practicing Tai Chi Yunshou movement.Methods Thirty Tai Chi beginners,including 15 patients with KOA and 15 healthy controls,were recruited to practice Tai Chi Yunshou movement for two hours under the guidance of a Tai Chi expert.A motion capture system and a three-dimensional force platform were used to collect and calculate dynamic stability parameter as well as kinematic and kinetic parameters of the left lower limb during the Yunshou movement.Results Compared with healthy controls,patients with KOA demonstrated a smaller center of mass(COM)-center of pressure(COP)inclination angle,reduced mean and peak ankle dorsiflexion angle,reduced peak hip adduction angle and increased peak knee flexion moment during the Yunshou movement(P<0.05).Conclusions Patients with KOA use adaptive postural strategies to maintain the lateral stability in Tai Chi Yunshou exercise,but a comprehensive training programme should be recommended to reduce the joint loading during flexion of the lower limbs at the benginning stages of this exercise.
