Objective To investigate current status of preschool children's social competence and its relation to tempera-ment type. Methods A total of 1 251 children participated in this study. The questionnaire was conducted and the children were assessed usinginfant-junior middle school student's ability of social life scaleandchildren's temperament scale. Results No significant gender difference was observed in total score of social competence (P>0.05). The total score of live independently was higher in girls as compared to boys (P<0.05). A significant gender difference was observed in classified scores of social competence (P<0.05). Girls with excellent or better-than-normal social competence were more than boys (P<0.05). The distribu-tion of the temperament type in preschool children were the difficult-to-raise type (8.1%), the start-slow type (15.4%), the stan-dard type (69.0%) and the easy-to-raise type (7.5%). There was statistically gender significance (P<0.05) in the distribution of the temperament types. The percentage of difficult-to-raise type was higher in girls than in boys. The percentage of easy-to-raise type was higher in boys than in girls. The total score and classified scores of social competence had significant difference among children with different temperament types (P<0.05). Conclusions There is significant diffe-rence of social competence in chil-dren with different temperament types. Corresponding educational measures according to the child's temperament may be bene-fit to the development in preschool children.

Objective:To investigate the correlation between the location and volume of cerebral microbleeds (CMBs) and lacunar infarction (LI) in patients with cerebral small vessel disease (CSVD).Methods:Participants from the CSVD cohort in the Department of Neurology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Medical School of Nanjing University from February 2017 to March 2019 were enrolled retrospectively. All participants underwent magnetic resonance imaging scans, standardized clinical assessment and diagnosis. AccuBrain, an automatic brain segmentation and quantification software developed by the Chinese University of Hong Kong, was used to quantitatively analyze the volume of CMBs and white matter hyperintensities (WMHs). Ordered multi-class logistic regression analysis was used to determine the independent influencing factors of LI, and then multiple linear regression analysis was used to investigate the correlation between the volume of deep or infratentorial CMBs (DI-CMBs) and the number of LI. Results:A total of 317 patients with CSVD were included in the analysis, including 214 (67.5%) in the non-LI group, 43 (13.6%) in the single LI group, and 60 (18.9%) in the multiple LI group. The comparison of the three groups showed that older age, male, smoking, drinking, history of previous stroke or transient ischemic attack (TIA), lower levels of high-density lipoprotein cholesterol, larger CMBs and WMHs volume, higher enlarged perivascular spaces (EPVS) grade might be the risk factors for LI. Ordinal multivariable logistic regression analysis showed that male (odds ratio [ OR] 2.058, 95% confidence interval [ CI] 1.084-3.909; P=0.027), previous stroke or TIA history ( OR 1.962, 95% CI 1.089-3.535; P=0.025), larger WMH volume ( OR 8.716, 95% CI 4.034-18.832; P<0.001), higher EPVS grade ( OR 1.915, 95% CI 1.292-2.839; P=0.001), larger DI-CMB volume ( OR 1.022, 95% CI 1.006-1.038; P=0.008) or more DI-CMB number ( OR 1.187, 95% CI 1.005-1.403; P=0.044) were the independent related factors of LI. Multiple linear regression analysis showed that there was a significant correlation between the volume of DI-CMB and the number of LI ( r=0.330, P<0.001). Conclusion:In patients with CSVD, there is a significant correlation between DI-CMBs and LI.

ObjectiveTo explore the imbalance of paravertebral muscle group for patients with unilateral lumbar disc herniation. MethodsFrom January, 2022 to January, 2023, 30 patients with unilateral lumbar disc herniation (observation group) and 30 healthy people matching in general data (control group) were measured the tension and stiffness of multifidus and erector spinae with MyotonPRO, while the observation group was assessed with Visual Analogue Scale (VAS) for pain and Japanese Orthopaedic Association (JOA) score, and the time of disease was also recorded. ResultsThe mean of bilateral tension and hardness of multifidus and erector spinae was more in the observation group than in the control group (|t| > 5.407, P < 0.001), and the tension and hardness of multifidus and erector spinae of the affected side were more than those of the unaffected side in the observation group (|t| > 11.219, P < 0.001). The tension and hardness of multifidus and erector spinae of the affected side were positively correlated with VAS score (r > 0.942, P < 0.001), and negatively correlated with JOA score (|r| > 0.886, P < 0.001). ConclusionThe tension and hardness of multifidus and erector spinae of the affected side increase after unilateral lumbar disc herniation, resulting in asymmetry.

Organoids are three-dimensional structures formed by self-organizing growth of cells in vitro, which own many structures and functions similar with those of corresponding in vivo organs. Although the organoid culture technologies are rapidly developed and the original cells are abundant, the organoid cultured by current technologies are rather different with the real organs, which limits their application. The major challenges of organoid cultures are the immature tissue structure and restricted growth, both of which are caused by poor functional vasculature. Therefore, how to develop the vascularization of organoids has become an urgent problem. We presently reviewed the progresses on the original cells of organoids and the current methods to develop organoids vascularization, which provide clues to solve the above-mentioned problems.

ObjectiveTo evaluate the inter-rater and test-retest reliability of echo intensity of ultrasound image for quality of quadriceps femoris in patients with knee osteoarthritis (KOA). MethodsFrom March to December, 2021, 33 patients with unilateral KOA in Guangdong Provincial Second Hospital of Traditional Chinese Medicine were included. Ultrasound was used to observe the cross sections of rectus femoris (RF), vastus medialis (VM) and vastus lateralis (VL), and the images were saved. Two independent raters analyzed the average gray value of the picture with the Image J. One of the raters repeated the measurement. The intra-class correlation coefficient (ICC), standard error of measurement (SEM), minimum detectable change (MDC) and coefficient of variation (CV) were calculated and the Bland-Altman charts were drawn. ResultsThe gray value was higher in the RF, VM and VL in the affected side than in the healthy side (t > 2.262, P < 0.05). The inter-rater reliability was excellent, with ICC 0.982 to 0.995, SEM 1.60 to 3.82, CV 1.49% to 5.90%, and MDC value 4.43 to 10.59. The test-retest reliability of the rater was excellent, with ICC 0.969 to 0.990, SEM 2.37 to 5.41, CV 2.22% to 4.84%, and MDC value 6.57 to 15.00. Bland-Altman charts analysis showed that the consistency was good. ConclusionThe quadriceps femoris muscle quality is different between the affected and the healthy sides in patients with unilateral KOA. It is reliable to evaluate muscle echo intensity by Image J.
