Objective:This study aimed to investigate the correlation between serum chitinase-3 like-protein-1(YKL-40), matrix metalloproteinase-9(MMP-9), and imaging markers in middle-aged and elderly patients with cerebral small vessel disease(CSVD).It also sought to elucidate the mechanism underlying the onset and development of CSVD.Methods:A case-control study was conducted with 130 CSVD patients and 20 age-matched controls admitted to the Department of Neurology of the Second Affiliated Hospital of Zhengzhou University between December 2020 and November 2022.Based on their white matter hyperintensity(WMH)and enlarged perivascular spaces(EPVS)scores, CSVD patients were categorized into mild, moderate, and severe groups.Cerebral microbleeds(CMBs)were classified into non-lacunar, lacunar, non-CMBs, and CMBs groups.Patients' general data were collected, and serum levels of YKL-40 and MMP-9 were measured using ELISA.Results:The results showed 34 cases in the severe WMH group, 35 cases in the EPVS severe group, 90 cases in the group with lacunar and 65 cases in the group with CMBs.Statistically significant differences(both P<0.05)in serum YKL-40 and MMP-9 in WMH severe groups compared to age control group.Statistically significant differences(both P<0.05)in serum YKL-40 and MMP-9 in EPVS severe groups compared to age control group.The increase of serum YKL-40 and MMP-9 levels was an independent risk factor for the severity of WMH( OR=1.25, 95% CI: 0.164-0.289, P<0.05)( OR=1.13, 95% CI: 0.090-0.160, P<0.05)and EPVS( OR=1.05, 95% CI: 0.021-0.076, P<0.05)( OR=1.02, 95% CI: 0.006-0.026, P<0.05).There was no significant different in the serum YKL-40 and MMP-9 levels between lacunar group and non-lacunar group( P>0.05).The serum YKL-40 and MMP-9 levels in the group with CMBs were significantly higher than those in the group without CMBs( P<0.05).The ROC curve showed that the optimal cutoff point of YKL-40 was 0.38, the area under the curve was 0.669(95% CI: 0.569-0.768, P<0.01), the optimal cutoff point of MMP-9 was 0.40, and the area under the curve was 0.746(95% CI: 0.644-0.848, P<0.01). Conclusions:Changes in serum YKL-40 and MMP-9 levels in middle-aged and elderly patients with CSVD were found to be associated with various imaging markers, potentially contributing to the onset and development of CSVD.These findings may aid in early CSVD diagnosis and provide insights for potential interventions.

Objective: To investigate the factors affecting depression and anxiety symptoms among the elderly, so as to provide the basis for promoting mental health among the elderly. Methods: The elderly aged 60 years and above in Ningbo City, Zhejiang Province were recruited using the multistage stratified random sampling method from June to August 2022, and demographic information, lifestyle and self-rated health status were collected by questionnaires. The symptoms of depression and anxiety were assessed by the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 (GAD-7), respectively. The presence of depressive and anxiety symptoms was determined when both the PHQ-9 score and the GAD-7 score were 10 points and higher. Factors affecting depressive and anxiety symptoms were identified using a multivariable logistic regression model. Results: A total of 7 771 individuals were surveyed, including 3 490 males (44.91%) and 4 281 females (55.09%), and had a mean age of (72.11±6.79) years. The prevalence of depression and anxiety symptoms was 2.05%. Multivariable logistic regression analysis identified residence (urban area, OR=0.316, 95%CI: 0.201-0.498), sedentary duration (<3 h/d, OR=0.349, 95%CI: 0.232-0.525; 3-5 h/d, OR=0.458, 95%CI: 0.313-0.671), physical activity (≥3 times/week, OR=0.551, 95%CI: 0.373-0.815), sleep quality (poor, OR=2.491, 95%CI: 1.738-3.571), social isolation (OR=1.688, 95%CI: 1.148-2.481) and self-rated health (poor, OR=5.857, 95%CI: 3.547-9.671; normal, OR=1.903, 95%CI: 1.234-2.937) as the influencing factors for depression and anxiety symptoms among the elderly. Conclusion The prevalence of depression and anxiety symptoms among the elderly is associated with residence, sedentary duration, sleep quality, physical activity, social interactions and self-rated health status.

Objective The aim of this study was to investigate the impact and mechanisms of emodin on oxidative stress response in lipopolysaccharide(LPS)-induced murine mononuclear macrophages(RAW264.7).Methods Involved the use of LPS,RAW264.7 cells,and emodin.Experimental groups included a control group,LPS(1 μg/mL)group,and LPS(1 μg/mL)+emodin(15 μmmol/L)pretreatment group.Aldehyde malondialdehyde(MDA)content,intracellular reactive oxygen species(ROS)levels,and silent information regulator 2(Sirt2)expression were evaluated at 6,12,and 18 hours after LPS exposure.Additionally,RAW264.7 cells were pretreated with Sirt2 inhibitor AGK2(20 μmol/L)followed by LPS stimulation,and the above-mentioned parameters were assessed at 6 hours.Results Compared to the control group,MDA content,ROS levels,Sirt2 mRNA,and protein expression in RAW264.7 cells in the LPS group increased at all time points(all P<0.05).At 6 and 18 hours,MDA content and ROS levels in RAW264.7 cells in the LPS+emodin group decreased significantly(all P<0.05),while at 12 hours,ROS levels were lower in the LPS group compared to the LPS+emodin group(P<0.05).Sirt2 mRNA and protein levels significantly increased at all time points(all P<0.05)compared to the LPS group.In the LPS+emodin+AGK2 group,Sirt2 mRNA and protein levels decreased,and MDA content and ROS levels increased compared to the LPS+emodin group(all P<0.05).Conclusion LPS-induced oxidative stress in RAW264.7 cells and emodin attenuate LPS-induced oxidative stress in RAW264.7 cells through Sirt2.

Objective To investigate the effects and molecular mechanisms of decorin(DCN),imatinib mesylate,and sunitinib malate on the malignant phenotype of gastrointestinal stromal tumor cells.Methods Western blotting was used to detect changes in the expres-sion of DCN and its downstream proteins after DCN overexpression and treatment with imatinib mesylate and sunitinib malate alone or in combination in gastrointestinal stromal tumor cells(GIST-882).Cell counting kit-8,scratch,and Transwell assays were performed to validate the changes in cell proliferation,migration,and invasion abilities after DCN overexpression and treatment with imatinib mesylate and sunitinib malate alone or in combination in GIST-882 cells.Results Compared with the control group,DCN overexpression and treatment with imatinib mesylate and sunitinib malate alone or in combination in GIST-882 cells increased the expression levels of DCN protein,decreased the expression levels of epidermal growth factor receptor(EGFR),phosphorylated EGFR(p-EGFR),extracellular signal-regulated kinase 1/2(ERK1/2),and phosphorylated ERK1/2(p-ERK1/2)proteins,and significantly reduced cell proliferation,migration,and invasion abilities.Conclusion DCN overexpression and treatment with imatinib mesylate and sunitinib malate alone or in combination affect the MAPK signaling pathway by downregulating the expression of EGFR,thereby regulating the proliferation,migra-tion,and invasion abilities of gastrointestinal stromal tumor cells.

Objective: To explore the emotional and behavioral problems of different only child and multiple child families, and to provide a reference for developing effective parenting styles. Methods: A stratified random cluster sampling method was adopted to investigate 2 647 guardians of preschool children in Tongling City from April to June, 2022. Children s emotional and behavioral problems were evaluated by using the self designed parenting questionnaire and the Children s Strengths and Difficulties Questionnaire (SDQ) parent edition. Results: The abnormal total score detection rate of emotional and behavioral problems of preschool children was 15.5%, and the rate of abnormal peer interaction was the highest (19.5%). In multiple child families, the first born child (17.5%, 20.4%), compared with the second and third child (11.5%, 9.5%), was more likely to exhibit conduct and hyperactivity problems ( χ 2=8.44, 29.75, P <0.01). There were differences in parenting attitudes between only child and multiple child families( χ 2=9.38, P <0.05). The results of the Logistic regression analysis showed that more frequent parent child discussion, the persuasive education and consistent family discipline strategy were negatively related to the emotional and behavioral problems of only children and children in multiple child families ( OR =0.15, 0.49, 0.38; 0.34, 0.40, 0.42, P <0.05). However, harmonious family relationships were only negatively related to emotional and behavioral problems in only children ( OR =0.08, P <0.01), and a higher education level among mothers was negatively related to emotional and behavioral problems in children from multiple child family environments( OR=0.30, 0.45, P <0.05). Conclusion The emotional and behavioral problems are serious of preschool children in Tongling City, the psychological development of the oldest children from multiple child and only child families should be actively followed, as this would help to promote a better understanding of the development of preschool children s physical and mental health.

Total glucosides of Rhizoma Smilacis Glabrae (RSG) are selective immunosuppressants that exhibit primary efficacy in the treatment of rheumatoid arthritis through targeted inhibition of activated T cells. In this study, we aimed to investigate the potential application of RSG in the treatment of psoriasis and elucidate its mechanism of action and material basis. Our findings revealed significant improvements upon administration of RSG in an imiquimod (IMQ)-induced psoriasis model. These improvements were characterized by a remarkable increase in the number of tail scales in mice and a substantial amelioration of skin erythema, ulceration, and flaking. By transcriptome sequencing and T-cell flow sorting assay, we identified notable effects of RSG on the modulation of various cellular processes. Specifically, RSG prominently down-regulated the Th17/Treg ratio in damaged skin tissues and reduced the proportion of G₂ phase cells. Furthermore, RSG exhibited a stimulatory effect on the proliferation and differentiation of epithelial cells. Of particular interest, we discovered that β-sitosterol, sitostenone, stigmasterol, smiglanin, and cinchonain Ib displayed potent inhibitory effects on the IL-17-mediated inflammatory response in HaCaT cells. In summary, our study highlights the therapeutic potential of RSG in the treatment of psoriasis, attributed to its ability to regulate the Th17/Treg balance. These findings contribute to the development of new indications for RSG and provide a solid theoretical foundation for further exploration in this field.

Objective: To examine the eating behaviors and associated factors among preschool children from multiple child families, so as to provide a basis for promoting healthy eating habits in this population. Methods: From April to June 2022, a stratified random cluster sampling method was employed to selected 2 647 guardians of preschool children in 11 kindergartens in Tongling City. Parenting style questionnaire, Identification and Management of Feeding Difficulty Questionnaire (IMFeD), Caregiver s Feeding Style Questionnaire (CFSQ) and a self designed questionnaire were administered. Multiple linear regression was performed to analyze the factors influencing eating behaviors among preschool children. Results: In the study, the detection of eating behavior problems among preschool children was 71.4%, and the detection of reduced appetite was the highest (55.6%). The detection rates of anorexia, picky eating, poor eating and improper eating behavior in only child families were higher (60.6%, 41.0%, 32.0%, 19.5%), compared with those in multiple child families (51.7%, 36.4%, 27.2%, 16.6%) ( χ 2=20.05, 5.95, 7.16, 3.92, P < 0.05 ). Among multiple child families, the detection rates of fear of eating and underlying disease were the lowest in 5-<10-year-old group (2.3%, 0.6%) ( χ 2=11.54, 8.51, P <0.05). In multiple child families, the detection rates of picky eating and poor eating habits for the first-born child were higher (42.0%, 32.5%), compared with second born and third born child (34.6%, 25.6%)( χ 2= 6.15, 6.38, P <0.05). The results of multiple linear regression analysis showed that multiplechild families ( β =-1.40), democratic parenting style ( β =-0.07), higher feeding response scores ( β =-0.33) were negatively associated with eating behavior problems among preschool children ( P <0.05). Eating behavior problems among preschool children were positively correlated with less educated mothers [high and junior high school education ( β =0.87), primary school education and below ( β =3.69)], longer average daily screen time ( β =0.10), higher feeding requirements scores ( β =0.64), doting parenting styles ( β =0.21), permissive parenting styles ( β =0.27) and inconsistent parenting styles ( β =0.14)( P <0.05). Conclusion The detection rate of the eating behaviors problems among preschool children is high in schools. Greater attention should be paid to only child and first born child of multiple child families, and appropriate feeding and parenting styles, so as to promote healthy eating habits among this population.

Objective:To compare the value of Caprini, Padua and Autar risk assessment models in the risk assessment of venous thromboembolism in hospitalized stroke patients.Methods:A retrospective case-control study were used to collect hospitalized stroke patients in the neurology department of Xiangya Hospital from January 1, 2018 to June 30, 2020. 75 patients with venous thromboembolism (VTE) were VTE group and 75 patients without VTE were control group. The risk of thrombosis was assessed by Caprini risk assessment model, Padua risk assessment model and Autar risk assessment model respectively. The predictive value of each model on the risk of VTE formation in stroke patients was analyzed by receiver operating characteristic (ROC) curve and area under the curve (AUC).Results:The areas under the curve of Caprini, Padua and Autar risk assessment models for predicting the risk of VTE formation in stroke patients were 0.768±0.039, 0.746±0.040 and 0.710±0.042 respectively. The sensitivity, specificity and accuracy were 81.3%, 61.3%, 71.3%(Caprini), 72.0%, 72.0%, 72.0%(Padua), 66.7%, 68.0% and 67.3%(Autar) respectively. There was no significant difference in the prediction value of the three models on the formation risk of stroke VTE (all P>0.05). The technique for order preference by similarity to ideal solution (TOPSIS) method was used to comprehensively evaluate the AUC, sensitivity, specificity and accuracy of the three risk assessment models. Padua risk assessment model was the best, followed by Caprini risk assessment model and Autar risk assessment model. Conclusions:The Caprini, Padua, and Autar risk assessment scales can well predict the risk of VTE in stroke patients. The Caprini scale has the highest sensitivity and the Padua scale has the highest specificity. There is no significant difference in the predictive value of the three scales. Comprehensive evaluation of predictive value: Padua risk assessment scale is the best.

Objective:To explore the ability of the Hammersmith Infant Neurological Examination (HINE) to predict the gross motor development of high-risk infants.Methods:A total of 207 high-risk infants were assessed with the HINE and the Gesell Developmental Schedule (GDS) at the ages of 3, 6, 9 and 12 months. They were then divided into a normal development group and a delayed group according to their gross motor development at 12 months old. The validity of the HINE′s discrimination was quantified retrospectively as the difference in the total HINE score at each follow-up month between the two groups. Spearman coefficients relating the total HINE score with the gross motor development quotient from the GDS were calculated at each follow-up month. The HINE′s total score threshold for predicting gross motor retardation at 12 months was determined from a receiver operating characteristics curve, and the predictive validity, sensitivity and specificity were evaluated by calculating the area under the curve.Results:At each time point the average total HINE score of the delayed group was significantly lower than the normal group′s average. The correlation between the HINE total scores and the GDS gross motor development quotients was strongest at 6 months old, and weakest at 3 months. The threshold total HINE score for predicting gross motor retardation at 12 months old was 60 at 3 months, 67 at 6 months, and then 71. The instrument′s sensitivity and specificity were very good at all four time points.Conclusion:The HINE can usefully predict gross motor retardation in the first year of life for high-risk infants. The critical value of the total score can be used as an auxiliary diagnostic reference for neuromotor development in such infants.
