Objective:To investigate the effects of deep core muscle training on pain and motor control during load trans-fer activities in patients with postpartum pelvic girdle pain(PPGP),and to explore the potential mechanisms by which deep core stability training alleviates PPGP pain.Method:From July 2024 to April 2025,56 PPGP women at the Affiliated Rehabilitation Hospital of Fujian University of Traditional Chinese Medicine were randomly divided into a control group(n=28)and an experi-mental group(n=28).Both groups received conventional treatment,while the experimental group underwent deep core stability muscle training in addition to the conventional treatment,three times a week for eight con-secutive weeks.Before and after the treatment,real-time ultrasound was used to assess the thickness of the transversus abdominis muscle(TrA)during maximal expiratory contraction,the thickness during ASLR activity,priority activation rate,the elastic modulus,and the elastic velocity,which reflect the changes in the move-ment control ability of the TrA muscle.The pelvic girdle questionnaire(PGQ)was used to assess the changes in pain and functional impairment in patients,with pain intensity assessed using the visual analogue scale(VAS),and the ASLR score used to assess the changes in load transfer activity ability between the trunk and lower limbs.Result:After eight weeks of treatment,the thickness of the TrA contraction during maximal expiratory and ASLR activity in the experimental group was significantly greater than that in the control group(P<0.05),and the contraction rate during breathing and the pre-activation rate during activation were both significantly higher than those in the control group(P<0.05).The percentage of internal oblique muscle activation in the experimental group during maximal expiration was significantly lower than that in the control group(P<0.05).The elastic modulus of TrA in the experimental group at rest,during maximal expiration,and during ASLR testing were all significantly greater than those in the control group(P<0.05).In addition,the results of pain scores and functional scales showed that the VAS score,PGQ score,and the ASLR score in the experimental group were all significantly lower than those in the control group after intervention(P<0.05).Conclusion:The deep core muscle training program can effectively alleviate pain and improve function in pa-tients with PPGP,and its mechanism may be related to enhancing TrA function and the motor control during load-transfer activities in PPGP.

BackgroundThe professional self-concept of nurses is a crucial indicator for their personal growth， development and career planning. Previous studies have shown that work stressors during the internship period may lead to a decrease in the level of professional self-concept among nursing students. Given the existing differences in social roles between nursing students and clinical nurses， the influencing factors of professional self-concept in clinical nurses and its relationship with work stressors require further research. ObjectiveTo explore the relationship between work stressors and professional self-concept among nurses， so as to provide references for improving the level of professional self-concept of clinical nurses. MethodsFrom December 2022 to February 2023， a stratified random sampling method was employed to select 260 in-service nurses from Mianyang Hospital of Traditional Chinese Medicine as the study subjects. Chinese Nurses Stressor Scale （CNSS） and Professional Self-concept of Nurses Instrument （PSCNI） were used for assessment. Pearson correlation analysis was conducted to examine the correlation between CNSS scores and PSCNI scores of nurses. Multiple linear regression analysis was utilized to explore the factors influencing the professional self-concept of nurses. ResultsA total of 238 nurses （91.54%） completed valid questionnaires. PSCNI total score yielded a statistical difference among nurses with different marital statuses （F=8.947， P<0.05）. PSCNI total scores were significantly higher in nurses with emergency medical service experience than those without such experience （t=2.208， P<0.05）， and were significantly lower in nurses with abnormal physical examination findings in the past year than those without abnormal findings （t=-2.584， P<0.05）. Correlation analysis revealed that CNSS total score and subscale scores were negatively correlated with PSCNI total score （r=-0.275~-0.169， P<0.01）. Multiple linear regression analysis indicated that work expectation-related stressors， marital status and emergency medical service experience might be influencing factors of their professional self-concept （β=-0.350， 0.345， 0.183， P<0.01）. ConclusionNurses' work stressors are closely correlated with their professional self-concept， and high levels of stressors related to nurses' expectations may lead to a decrease in their professional self-concept levels. ［Funded by 2021 Research Project of Mianyang Municipal Health Commission （number， 202154）］

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.

BACKGROUND:Mechanical factors can affect the angiogenic ability of vascular endothelial cells.How the vessel number affects the hydrodynamic properties of microvessels remains to be clarified. OBJECTIVE:To investigate the influence of vessel number on the hydrodynamics of vascular networks based on computational fluid dynamics. METHODS:Three three-dimensional models of vascular network with different vessel numbers were constructed using the Geometry module of ANSYS 19.0 software,and then the vascular network was meshed to tetrahedral elements in Mesh module.The vascular network was assumed to rigid wall without slip,and the blood was assumed to laminar,viscous,and incompressible Newtonian fluid.Blood density,velocity,and a series of blood viscosity coefficients were also established.The Navier-Stokes equation was used for calculation.Hydrodynamic properties of different parts of vascular network with different vessel numbers were analyzed and compared. RESULTS AND CONCLUSION:The streamline,velocity,and mass flow all had the same trend in the vascular network,that is,the outlet and inlet were higher and the middle junction of vascular network was lower.The more the number of vessels,the thinner the blood flow lines in each part of the vascular network.Also,the velocity,mass flow,and wall shear decreased with the increase of the number of blood vessels.Therefore,the changes in vessel number could influence the hydrodynamic environment in the vascular network.Computational fluid dynamics indicates that the changes in vessel numbers can influence the hydrodynamic properties of blood,and provides a new idea for treating bone hypoperfusion-induced diseases(fracture nonunion,bone defect,osteoporosis,etc.)through tonifying kidney and activating blood circulation based on the coupling between angiogenesis and osteogenesis.
