Objective: To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children. Methods: Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model. Results: Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats. Conclusions Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

Objective: To investigate the effect of auricular therapy on sleep improvement and the GABAergic system pathway in a rat model of insomnia and to explore its possible mechanism. Methods: According to the random number table, 60 male SD rats were randomly divided into blank control, model, auricular point sticking, auricular bloodletting, and auricular bloodletting combined with sticking groups, with 12 rats per group. Insomnia was induced by intraperitoneal injection of p-chlorophenylalanine. After establishing the insomnia model, 36 rats were treated once a day with auricular point sticking or bloodletting for 5 consecutive days. After the intervention, the general condition and body weight of rats were observed; the righting reflex test was used to detect the sleep latency and duration; HE staining was used to observe the morphology of hypothalamic neuron cells; and an enzyme-linked immunosorbent assay was used to detect the GABA and glutamate content in rat serum. Immunohistochemistry(IHC) and real-time fluorescence quantitative PCR were used to detect GABA ARα1 and GABA ARγ2 protein and mRNA expression in the hypothalamus of rats, and Western blotting(WB) was used to detect GABA ARα1, GABA ARγ2, GAD65/67, GAT-1, and GABA-T protein expression in the hypothalamus of rats. Results: Compared with the blank control group, the model group had a lower body weight, a significantly shorter sleep duration (P<0.05), severe damage to the morphological structure of hypothalamic neurons with disordered cell arrangement, larger intercellular gaps, enlarged cell bodies, and a vacuolated appearance. All the intervention groups had significantly higher body weight and longer sleep duration than the model group (P<0.05). Compared with the other intervention groups, the auricular point sticking group had a longer sleep duration (P<0.05), and the hypothalamic neuron cells in all intervention groups improved, with the auricular point sticking group showing more apparent improvement. The model group had a lower GABA and higher glutamate contents, and GABA ARα1, GABA ARγ2, and GAD65/67 protein expression in the hypothalamus were lower than in the blank control group. In contrast, GAT-1 and GABA-T protein expression was higher, and GABA ARα1 and GABA ARγ2 mRNA expression was lower (P<0.05). The serum GABA content in the auricular point sticking and auricular bloodletting groups was higher, and the serum glutamate content in the auricular point sticking and auricular bloodletting combined sticking groups was lower than in the model group. GABA ARα1 mRNA expression in the hypothalamus of each intervention group was significantly increased, and GABA ARγ2 mRNA expression in the hypothalamus of the auricular point sticking and auricular bloodletting combined sticking groups increased. GABA ARα1(IHC, WB), GABA ARγ2(WB), and GAD65/67 protein expression in the hypothalamus of the auricular point sticking group increased, whereas GAT-1 and GABA-T protein expression decreased. GABA ARα1 and GABA ARγ2 protein expression(IHC, WB) in the hypothalamus of the auricular bloodletting group increased, whereas GABA-T protein expression decreased. GABA ARγ1(IHC) and GABA ARγ2(WB) protein expression in the hypothalamus of the auricular bloodletting combined sticking group increased, whereas GAT-1 and GABA-T protein expression decreased (P<0.05). Compared with in the inventation groups, the serum GABA content in the auricular point sticking group increased, the serum glutamate content decreased, GABA ARα1 and GABA ARγ2 mRNA expression in the hypothalamus increased, and GABA ARα1(IHC), GAD65/67 protein expression increased. In contrast, GABA-T protein expression decreased (P<0.05), and GABA ARγ2 protein expression(IHC) in the hypothalamus of the auricular bloodletting group increased (P<0.05). Conclusion Auricular therapy, particularly auricular point sticking, may have modulated the GABAergic system pathway by upregulating hypothalamic GABA ARα1, GABA ARγ2, and GAD65/67 protein expression while downregulating GAT-1 and GABA-T protein expression to alleviate symptoms in an insomnia rat model.

[Objective] : To explore the clinical characteristics and methods for syndrome differentiation prediction, as well as to construct a predictive model for Qi deficiency and blood stasis syndrome in patients with acute ischemic stroke (AIS). [Methods] : This study employed a retrospective case-control design to analyze patients with AIS who received inpatient treatment at the Neurology Department of The First Hospital of Hunan University of Chinese Medicine from January 1, 2013 to December 31, 2022. AIS patients meeting the diagnostic criteria for Qi deficiency and blood stasis syndrome were stratified into case group, while those without Qi deficiency and blood stasis syndrome were stratified into control group. The demographic characteristics (age and gender), clinical parameters [time from onset to admission, National Institutes of Health Stroke Scale (NIHSS) score, and blood pressure], past medical history, traditional Chinese medicine (TCM) diagnostic characteristics (tongue and pulse), neurological symptoms and signs, imaging findings [magnetic resonance imaging-diffusion weighted imaging (MRI-DWI)], and biochemical indicators of the two groups were collected and compared. The indicators with statistical difference (P < 0.05) in univariate analysis were included in multivariate logistic regression analysis to evaluate their predictive value for the diagnosis of Qi deficiency and blood stasis syndrome, and the predictive model was constructed by receiver operating characteristic (ROC) curve analysis. [Results] : The study included 1 035 AIS patients, with 404 cases in case group and 631 cases in control group. Compared with control group, patients in case group were significantly older, had extended onset-to-admission time, lower diastolic blood pressure, and lower NIHSS scores (P < 0.05). Case group showed lower incidence of hypertension history (P < 0.05). Regarding tongue and pulse characteristics, pale and dark tongue colors, white tongue coating, fine pulse, astringent pulse, and sinking pulse were more common in case group. Imaging examinations demonstrated higher proportions of centrum semiovale infarction, cerebral atrophy, and vertebral artery stenosis in case group (P < 0.05). Among biochemical indicators, case group showed higher proportions of elevated fasting blood glucose and glycated hemoglobin (HbA1c), while lower proportions of elevated white blood cell count, reduced hemoglobin, and reduced high-density lipoprotein cholesterol (HDL-C) (P < 0.05). Multivariate logistic regression analysis identified significant predictors for Qi deficiency and blood stasis syndrome including: fine pulse [odds ratio (OR) = 4.38], astringent pulse (OR = 3.67), superficial sensory abnormalities (OR = 1.86), centrum semiovale infarction (OR = 1.57), cerebral atrophy (OR = 1.55), vertebral artery stenosis (OR = 1.62), and elevated HbA1c (OR = 3.52). The ROC curve analysis of the comprehensive prediction model yielded an area under the curve (AUC) of 0.878 [95% confidence interval (CI) = 0.855 – 0.900]. [Conclusion] This study finds out that Qi deficiency and blood stasis syndrome represents one of the primary types of AIS. Fine pulse, astringent pulse, superficial sensory abnormalities, centrum semiovale infarction, cerebral atrophy, vertebral artery stenosis, elevated blood glucose, elevated HbA1c, pale and dark tongue colors, and white tongue coating are key objective diagnostic indicators for the syndrome differentiation of AIS with Qi deficiency and blood stasis syndrome. Based on these indicators, a syndrome differentiation prediction model has been developed, offering a more objective basis for clinical diagnosis, and help to rapidly identify this syndrome in clinical practice and reduce misdiagnosis and missed diagnosis.

Objective:To investigate variation of peripheral blood monocyte subtypes in patients with rheumatoid arthritis(RA),to study variation of surface antigen expression intensity and plasma related cytokine content of monocytes of each subtype,and to discuss their clinical application value.Methods:Percentage of monocyte subtypes and mean fluorescence intensity(MFI)of monocyte surface markers(HLA-DR,CD64,CD11b)in peripheral blood of 38 patients with RA were detected by multi-parameter flow cytometry,and differences were statistically analyzed compared with 40 healthy controls(HV group).Plasma levels of five cyto-kines(IL-2,IL-6,IL-10,TNF-α and IFN-γ)were detected by flow fluorescence microsphere technology.Linear correlation analysis was performed to determine correlation between percentage of monocyte subtypes and MFI of their surface markers and expression of related cytokines in RA patients.Disease activity 28(DAS28)score was performed in RA patients to study its association with percent-age of monocyte subtypes and plasma cytokines.Results:Compared with control group,percentage of classical monocytes in RA pa-tients decreased significantly(P<0.05),while percentage of intermediate monocytes and non-classical monocytes increased signifi-cantly(P<0.01).HLA-DR expression(MFI)on monocyte subsets in RA group was significantly higher than HV group(P<0.05 or P<0.01).CD64 expression(MFI)on intermediate monocytes and non-classical monocytes in RA group was significantly higher than HV group(P<0.01 or P<0.001).CD11b expression(MFI)on intermediate monocytes in RA group was significantly higher than HV group(P<0.001).In RA group,percentage of intermediate monocytes was positively correlated with contents of IL-6,TNF-α and IFN-γ(P<0.01).HLA-DR expression(MFI)on intermediate monocytes was positively correlated with TNF-α content(P<0.05);CD64 expres-sion(MFI)on non-classical monocytes was positively correlated with contents of IL-2 and IL-10(P<0.05).In RA group,percentage of intermediate monocytes was positively correlated with DAS28(P<0.001);plasma IL-6 and TNF-α levels were positively correlated with DAS28(P<0.01).Conclusion:Characteristic expression of intermediate monocytes and their surface antigens are closely related to occurrence of RA,and related inflammation is triggered by secretion of related cytokines.Monocyte subtype detection can be a new experimental diagnostic index for RA.Dynamic monitoring of peripheral blood monocyte subtypes and plasma IL-6 and TNF-α in RA patients during treatment is helpful to guide clinical treatment of RA.

BACKGROUND:Pro-kin balance system guidance has a relatively excellent rehabilitation effect on lower extremity proprioception and trunk control in stroke patients,but its effect on knee proprioception and balance function in patients after anterior cruciate ligament reconstruction has been less reported. OBJECTIVE:To investigate the effect of rehabilitation training guided by Pro-kin balance system on proprioception and balance function of the affected knee after anterior cruciate ligament reconstruction. METHODS:A total of 84 patients who underwent anterior cruciate ligament rupture reconstruction surgery were randomly divided into observation group and control group,with 42 patients in each group.The patients in the control group received routine rehabilitation intervention after surgery,and those in the observation group were given rehabilitation training based on the guidance of Pro-kin balance system.The training in each group lasted for 8 weeks.Lysholm score and International Knee Documentation Committee score were used to evaluate the change of knee joint function before and after the intervention.Average weight-bearing strength difference,trajectory error,swing value and 30°,45° and 60° passive angulation errors of the affected knee joint were used to evaluate the changes in the proprioception of the affected knee.The area and length of motion trajectory under open and closed eyes were used to evaluate the change of balance function.The satisfaction of patients in both groups with this rehabilitation training was investigated. RESULTS AND CONCLUSION:After training,Lysholm score and International Knee Documentation Committee score of patients in both groups were significantly higher than those before training(P<0.01),and the above scores in the observation group were significantly higher than those in the control group(P<0.01).After training,the average weight-bearing strength difference,trajectory error and swing value of the two groups were significantly lower than those before training(P<0.01),and the above scores in the observation group were significantly lower than those in the control group(P<0.01).After training,the passive angulation errors of 30°,45° and 60° of the affected knee joints in both groups were significantly lower than those before training(P<0.01),and those in the observation group were significantly lower than those in the control group(P<0.05,P<0.01).After training,the area and length of motion trajectory in both groups with eyes open were significantly smaller than those before training(P<0.01),and the above indicators in the observation group were significantly smaller than those in the control group(P<0.05,P<0.01).After training,the area and length of the movement track of the patients in both groups with eyes closed were significantly smaller than those before training(P<0.01),and the above indicators in the observation group were significantly smaller than those in the control group(P<0.01).The satisfaction of patients in the observation group was 95,which was significantly higher than 81%in the control group(P<0.05).To conclude,compared with the conventional rehabilitation training,the rehabilitation training based on Pro-kin balance system is more effective in improving the function,proprioception and balance function of the affected knee joints of patients undergoing anterior cruciate ligament rupture reconstruction,and the patients'satisfaction is higher.

Objective:To analyze the related factors that affect the occurrence of femoral head necrosis in patients with femoral neck fracture after surgery, and to build a nomogram predictive model.Methods:Using a retrospective study method, 180 patients with femoral neck fracture who were admitted to Hainan Provincial Hospital of Traditional Chinese Medicine from June 2019 to October 2021 were selected as the study objects. According to whether the patients had femoral head necrosis, they were divided into the occurrence group (75 cases) and the non occurrence group (105 cases). The receiver operating characteristic (ROC) curve was used to analyze the predictive value; Logistic regression was used to analyze the risk factors of postoperative femoral head necrosis; internal data were used to verify the clinical efficacy of nomogram model.Results:There was no significant difference in age, sex, body mass index and other general data between the two groups ( P>0.05); compared with the non occurrence group, Garden fracture in the occurrence group was mostly classified as type Ⅲ or Ⅳ, and more patients with preoperative traction, fracture displacement and unsatisfactory reduction quality, and the time from trauma to surgery was longer ( P>0.05). The area under curve of the time from trauma to surgery was 0.766 (95% CI 0.697 to 0.826), and the optimal cutoff value was 42 h; Garden fracture classification (type Ⅲ or Ⅳ), preoperative traction (yes), fracture displacement (yes), reduction quality (unsatisfactory) and time from trauma to surgery (>42 h) were the risk factors affecting the postoperative femoral head necrosis in patients with femoral neck fracture ( P<0.05). The risk of femoral head necrosis predicted by nomogram model was 0.802 (95% CI 0.692 to 0.873). The risk threshold of femoral head necrosis predicted by the model was >0.09, and nomogram model provides clinical net income. Conclusions:Garden fracture classification (type Ⅲ or Ⅳ), preoperative traction (yes), fracture displacement (yes), reduction quality (unsatisfactory) and time from trauma to surgery (>42 h) are the risk factors affecting the postoperative femoral head necrosis in patients with femoral neck fracture, and the nomogram model based on variables has a better predictive ability.

Objective:To analyze the results of lymphocyte subsets and 12 plasma cytokines in patients with tuberculosis by flow cytometry and to evaluate their diagnostic efficacy in these patients.Methods:This is a retrospective case-control study. A total of 128 patients with evidence of tuberculosis disease or clinically confirmed tuberculosis who were admitted to the 8th Medical Center of PLA General Hospital from January 2022 to December 2023 were included. According to the location of mycobacterium tuberculosis infection, the patients were divided into the pulmonary tuberculosis group (83 cases) and the extrapulmonary tuberculosis group (45 cases), and 100 healthy age-and sex matched people who underwent health check up during the study period were selected as the control group. Flow cytometry was used to detect peripheral blood lymphocyte subsets and 12 plasma cytokines [including 10 pro-inflammatory factors: interleukin (IL)-5, interferon (IFN)-α, IL-2, IL-6, IL-1β, IFN-γ, IL-8, IL-17, IL-12P70, Tumor necrosis factor (TNF)-α, and two anti-inflammatory factors: IL-4, IL-10] in participants of all groups. Spearman correlation method was used to analyze the correlation between lymphocyte subsets and cytokines, binary Logistic regression was used to screen the TB related factors, and receiver operating curve (ROC) was used to evaluate the diagnostic efficacy of TB related factors.Results:Compared with the control group, the absolute number of CD3 +T lymphocytes, CD3 +CD8 +T lymphocytes, CD3 +CD4 +T lymphocytes, NK cells and B cells were lower in pulmonary tuberculosis group and extrapulmonary tuberculosis group (all P<0.05). Except for IL-1β, the levels of other 11 cytokines are all significantly higher in the pulmonary tuberculosis group (all P<0.01), and the levels of IL-6, IFN-γ, IL-17, TNF-α, IL-4 and IL-10 were significantly higher in extrapulmonary tuberculosis group (all P<0.05). Compared with extrapulmonary tuberculosis group, the level of IL-8 was higher in pulmonary tuberculosis group ( P=0.026). Spearman correlation analysis showed that IL-6, IFN-γ and IL-8 were negatively correlated with the absolute numbers of CD3 +T lymphocytes, CD3 +CD8 +T lymphocytes, CD3 +CD4 +T lymphocytes, NK cells and B cells (IL-6: R2=-0.30, -0.28, -0.32, -0.26, -0.28; IFN-γ: R2=-0.36, -0.31, -0.37, -0.25, -0.36; IL-8: R2=-0.14, -0.13, -0.16, -0.14, -0.22; all P<0.05), IL-10 was negatively correlated with the absolute number of CD3 +CD4 +T lymphocytes, NK cells and B cells ( R 2=-0.14, -0.19, -0.21, all P<0.05); Binary Logistic regression analysis showed that IL-6, IFN-γ, IL-8 and IL-10 were the related factors of tuberculosis ( OR=1.809, 1.136, 0.910, 2.218, all P<0.05), ROC curve analysis showed that the AUC of IL-6, IFN-γ, IL-8 and IL-10 in the joint diagnosis of tuberculosis was 0.845, the sensitivity was 0.766, and the specificity was 0.820. Conclusion:The lower absolute number of lymphocyte subsets and cytokine levels in patients with pulmonary tuberculosis and extrapulmonary tuberculosis indicate that their immune function is in a low state, and the higher levels of pro-inflammatory factors (IL-6, IFN-γ, IL-8) and anti-inflammatory factor (IL-10) indicates the higher inflammatory status, and evaluation of these 4 cytokines has satisfactory diagnostic efficacy for tuberculosis.
