Objective:
To understand the allocation and use of safety seats for preschool children and explore its related factors, so as to provide a scientific reference for promoting the usage of safety seats.
Methods:
A stratified random cluster sampling method was used to select 3 143 parents of preschool children aged 3 to 6 from six kindergartens in Shunyi District, Beijing from January 3 to 10, 2022. An online questionnaire survey was conducted to collect and evaluate the equipment and use of child safety seats in different characteristics of preschool children, as well as their scores of health beliefs. Multiple factor Logistic regression analysis was used to investigated the related factors of safety seat configuration and use.
Results:
The equipping rate and usage rate of safety seats for preschool children were 66.56% and 58.45%, respectively. The proportion of equipped and used safety seats for preschool children in core families (69.52%, 62.23%) were higher than that in large families (64.35%, 55.62%), only child families ( 72.39 %, 64.87%) were higher than non only child families (61.49%, 52.86%), and urban families (71.63%, 63.04%) were higher than rural families (52.31%, 45.51%) ( χ 2=9.23, 13.86; 41.72, 46.44; 101.96 ,76.97,all P <0.05) . As the educational level of parents ( χ 2 trend =154.23,98.76) and annual income of the family ( χ 2 trend =155.78,127.69) rised, the reporting rates of the equipped and used child safety seats in the family also increased(all P <0.05 ). There were statistically significant differences in the scores of different dimensions of health beliefs for the provision ( t =-20.22-18.16) and use ( t =24.32-24.17) of safety seats for preschool children(all P <0.05). After adjusting for child sex, child age, family annual income, parental education level, family type, whether the child was an only child, and place of residence,multivariate Logistic regression analysis showed that preschool children with higher perceived susceptibility score( OR =1.11, 1.08), higher self efficacy score( OR =1.23, 1.33), and higher suggestive factors score( OR =1.08, 1.12) were more likely to have and use safety seats in their families, while preschool children with higher perceived impairments score( OR =0.82, 0.80) were less likely to have and use safety seats in their families (all P <0.05).
Conclusions
The installation rate of child safety seats needs to be improved, and there is also a certain gap in their use after installation. Parents of preschool children should improve susceptibility and self efficacy to safety seat equipment and use, and perceptual barriers should be reduced.

Infection is an important trigger for the initiation of pancreatic islet autoimmunity in type 1 diabetes mellitus (T1DM). From the perspective of latent pathogen and dryness disorder, this study analyzes the core pathogenesis and dynamic evolution of T1DM in the subclinical and clinical stages. Combined with the T1DM "constraint, heat, deficiency, damage" state and target differentiation and treatment theory, the course of infection-induced T1DM is divided into three stages, including latent dryness, dry-heat and collateral damage. The "latent dryness" stage corresponds to the subclinical phase of T1DM, while the "dry-heat" stage corresponds to the clinical phase, and the "collateral damage" stage corresponds to the phase in which chronic complications develop. Treatment principles include supplementing deficiency and dispelling pathogen during the "latent dryness" stage, clearing heat and moistening dryness in the "dry-heat" stage, and dissolving stasis and unblocking collaterals in the "collateral damage" stage. Furthermore, syndrome-targeted and target-directed therapeutic modifications were made according to T1DM-related autoimmune activity, metabolic comorbidities, and vascular comorbidities, providing a reference for clinical management of T1DM.

ObjectiveTo explore the possible mechanisms of Wenyang Huazhuo Formula (温阳化浊方, WHF) in improving reproductive aging from the perspective of the ovarian mechanical microenvironment. MethodsThe experiment included five groups, 3-month group (20 female mice at 3 months of age), 6-month group (20 female mice at 6 months of age), 6-month + WHF group (20 female mice at 5 months of age treated with WHF), 9-month group (20 female mice at 9 months of age), and 9-month + WHF group (20 female mice at 8 months of age treated with WHF). The 6-month + WHF group and 9-month + WHF group were orally administered WHF 41.2 g/(kg·d) once daily for 4 consecutive weeks. The other three groups received no intervention. Reproductive hormone levels were measured by ELISA. HE staining was used to count the numbers of various stages of follicles. Ovarian hyaluronic acid (HA) content and collagen fiber content were measured to evaluate the ovarian mechanical microenvironment. Superovulation was performed to observe the number of eggs obtained, as well as the number of offspring and birth weight to assess fertility. The in vitro fertilization and blastocyst culture of oocytes from female offspring in each group were observed to evaluate the effect of WHF on offspring reproductive potential. ResultsCompared with the 3-month group, the 6-month group and 9-month group showed significantly decreased serum levels of gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH), decreased ovarian collagen content, and reduced numbers of primordial and secondary follicles. In contrast, the numbers of primary follicles, antral follicles, and atretic follicles increased. The levels of anti-Müllerian hormone (AMH), ovarian HA content, and the fertilization rate, cleavage rate, and blastocyst formation rate of oocytes from offspring were significantly lower (P<0.05). Compared with the 6-month group, the 6-month + WHF group showed significantly reduced serum levels of GnRH, FSH, and LH, with a significant decrease in primary follicles, antral follicles, and atretic follicles as well as increase of AMH levels, ovarian HA content, number of primordial and secondary follicle, egg count, and offspring birth weight (P<0.05). Compared with the 9-month group, the 9-month + WHF group exhibited reduced GnRH, FSH, and collagen fiber content, as well as reduced number of primary follicles, antral follicles, and atretic follicles. However, AMH levels, ovarian HA content, number of primordial and secondary follicle, egg count, offspring numbers, birth weight, fertilization rate, cleavage rate, and blastocyst formation rate of oocytes from offspring all significantly increased (P<0.05). ConclusionWHF can significantly improve the ovarian reserve, fertility, and reproductive potential in offspring during reproductive mid-life and late-life stages. Its effect may be related to the remodeling of the mechanical microenvironment of aging ovaries. Moreover, the effect on the mechanical microenvironment remodeling of late-stage ovaries and the improvement of the offspring reproductive potential is more significant.

BACKGROUND:Dysfunction of macrophage efferocytosis can induce local and systemic inflammatory damage and is associated with a variety of obesity-related metabolic diseases.Moreover,compounds targeting efferocytosis have shown good therapeutic effects. OBJECTIVE:By reviewing the effects of obesity on macrophage efferocytosis,to analyze the key mechanism by which obesity inhibits efferocytosis,to summarize the research progress in compounds targeting efferocytosis to treat obesity-related metabolic diseases,so as to provide new ideas for fully understanding efferocytosis and its relationship with metabolic diseases,aiming to provide new strategies for disease prevention and treatment. METHODS:The English search terms were"efferocytosis,metabolism,obesity,obese,atherosclerosis,non-alcoholic steatohepatitis,neurodegeneration,tumor,osteoarthritis,diabetes,compound,medicine,treatment,"which were used for literature retrieval in PubMed and Web of Science.The Chinese search term was"efferocytosis,"which was used for literature retrieval in CNKI,VIP and WanFang datebases.Ninety-nine papers were finally included in the review analysis after a rigorous screening process. RESULTS AND CONCLUSION:In the process of efferocytosis,the"Find me"and"Eat me"processes involving a large number of apoptotic cell derived factors are mainly regulated by apoptotic cells.The efferocytosis factor involved in cytoskeletal remodeling and digestion are mainly derived from macrophages,which are crucial for efferocytosis activity.These results suggest that the"Find me"and"Eat me"factors mainly reflect the condition of apoptosis,and it is more scientific to select the expression of factors involved in cytoskeletal remodeling and digestion when evaluating the efferocytosis activity of macrophages.Obesity inhibits efferocytosis,and shows an inhibitory effect on most digestive factors,but has a stress-induced activation effect on most"Find me,""Eat me"and cytoskeletal recombination factors,which further indicates the decisive effect of digestive stage on efferocytosis and suggests that it is not reliable for some studies to evaluate the efferocytosis based on the increased expression of"Find me"and"Eat me"factors.Targeting cytokines in the digestive phase may be more effective when discussing future intervention strategies targeting macrophages efferocytosis.The efferocytosis activators of macrophages are effective in the treatment of various metabolic diseases,but the efferocytosis inhibitors in tumor tissue show good anticancer effects,suggesting that the role of efferocytosis should be rationally evaluated according to the characteristics of tissue inflammation.Efferocytosis is a relatively new concept proposed in 2003,with a short research history and complex efferocytosis factors.Current studies on obesity and efferocytosis only involve a tip of the iceberg and most of them are at a superficial level and a large number of scientific experiments are needed to further validate the mechanisms.

Objective:To investigate the clinical utility of functional near-infrared spectroscopy (fNIRS) in evaluating cerebral function in neonates with hypoxic-ischemic encephalopathy (HIE).Methods:This was a case-control study. Fifteen neonates with moderate to severe HIE who were admitted to the Department of Neonatal Medical Center, Children's Hospital of Fudan University from March 2023 to August 2024 and completed fNIRS testing were selected as the HIE group, and 15 full-term infants without neurological diseases and completed fNIRS testing were selected as the control group during the same period. Resting-state fNIRS data were acquired to construct cerebral functional connectivity networks and topological properties were analyzed. Statistical analyses included independent t-tests, Mann-Whitney U tests, analysis of variance, and Chi-square tests. Results:Compared with controls, the HIE group exhibited significantly reduced global functional connectivity strength [0.15 (0.05-0.26) vs. 0.24 (0.13-0.35), Z=-7.66, P<0.001]. Both groups demonstrated small-world network properties, with no intergroup difference (1.17±0.05 vs. 1.14±0.05, t=2.02, P=0.050). The HIE group showed decreased shortest path length (6.22±0.52 vs. 13.74±0.49, t=48.18, P<0.001), global efficiency (0.26±0.04 vs. 0.30±0.05, t=2.50, P=0.018) and normalized shortest path length (1.50±0.07 vs. 1.62±0.22, t=2.43, P=0.020). No differences were observed in the clustering coefficient or local efficiency between the two groups. Regional analysis revealed reduced nodal efficiency in both left (0.30±0.06 vs. 0.35±0.05, t=2.47, P=0.021) and right hemispheres (0.30±0.06 vs. 0.37±0.06, t=2.68, P=0.013) in HIE neonates compared with that of the corresponding hemispheres in the control group. The intra-group comparison showed no statistical significance in node efficiency between the left and right hemispheres (both P>0.05). Conclusion:fNIRS captures functional network signatures in HIE, demonstrating clinical potential for early detection of cerebral dysfunction in neonates with hypoxic-ischemic injury.

"When warm evil is received,it first attacks the lungs and then spread to the pericardium reversely"is the general rule of warm diseases.Doctors of different dynasties have different views on the phrase"reverse spread to the pericardium",especially the word"reverse".Professor Tong Xiaolin proposed that the heart governs the mind,the pericardium and the heart are connected in qi,and when the heart is affected by evil,the pericardium instead suffers from the evil.The"reverse spread to the pericardium"proposed by Ye Tianshi is actually the spread of warm evil to the brain.Taking meningococcal meningitis as the basic disease,it can be matched one by one with the typical stages of the transmission of Wei-Qi-Ying-Xue.Combined with the theory of Dingjiao,it is believed that the function of"the heart governing the mind"focuses more on the brain in the modern anatomical sense.Combining traditional Chinese medicine's ideas on diagnosis and treatment of warm diseases with modern medicine,revealing the essence of the disease,grasping the core of the pathogenesis,analyzing the word"reverse"from a new perspective,and exploring its true meaning,is of great significance for clarifying its connotation,exploring the development laws of warm diseases,and guiding the diagnosis and treatment of warm disea-ses.
