ObjectiveTo analyze the impact of maternal postpartum depression (PPD) at 2 months postpartum on caregiving for infants aged2 to 24 months, and to provide a scientific basis for future maternal and infant healthcare services. MethodsBased on the Shanghai Maternal-Child Pairs Cohort, 1 060 mother-child pairs were selected from those fully participating in follow-up visits at 2, 6, 12, and 24 months postpartum. Pregnancy and childbirth-related information was collected using standardized questionnaire surveys and hospital obstetric and maternity records. The Edinburgh postpartum depression scale was used to assess the maternal postpartum depressive symptoms at 2 months postpartum. At 2, 6, 12, and 24 months postpartum, questionnaire survey was used to evaluate the maternal responsiveness in caregiving and the provision of early learning opportunities for infants. Scores for responsive caregiving and early learning opportunities at 2, 6, 12, and 24 months were grouped based on the 25th percentile (P₂₅) of total scores. The mixed-effects model was used to analyze the longitudinal impact of maternal postpartum depression at 2 months on the caregiving of 2 to 24-month-old infants. ResultsThe longitudinal results from the mixed-effects model did not show an impact of maternal PPD on infant responsive caregiving within 12 months and early learning opportunities within24 months. However, cross-sectional analysis revealed that, compared to the non-PPD group, the risk of low responsive caregiving at 2 months in the PPD group was 93% higher (OR=1.931, 95%CI: 1.113‒3.364, P=0.019). The risks for low provision of early learning opportunities at2 months and 24 months increased by 59% (OR=1.589, 95%CI: 1.082‒2.324, P=0.017) and 60% (OR=1.598, 95%CI:1.120‒2.279, P=0.010), respectively. ConclusionMaternal postpartum depression increases the risk of low responsive caregiving at 2 months, but its long-term effects warrant further research.

OBJECTIVE To investigate the ameliorative effect of ursolic acid on skin inflammation in rats with allergic contact dermatitis （ACD）， and explore its mechanism of action based on the Notch1/hairy and enhancer of split 1 （Hes1） signaling pathway. METHODS The ACD model was established by skin application of 2， 4-dinitrochlorobenzene. Forty successfully modeled rats were randomly divided into model control group （MC group）， ursolic acid low-dose group （UA-L group， 50 mg/kg）， ursolic acid high-dose group （UA-H group， 100 mg/kg）， and ursolic acid high-dose+Notch1 activator group （UA-H+Jagged1 group， 100 mg/kg ursolic acid+50 ng/kg Jagged1）， with 10 rats in each group. Another 10 rats with only hair shedding were selected as the normal control group. Rats in the administration groups were given the corresponding dose of ursolic acid intragastrically or/and Jagged1 by intraperitoneal injection once a day for 14 consecutive days. Twenty-four hours after the last treatment， the skin inflammation status and dermatitis scores of rats in each group were detected. The levels of interleukin-6 （IL-6）， IL-17 and IL-10 in serum and skin tissue were detected by enzyme-linked immunosorbent assay. Hematoxylin-eosin staining was used to detect the pathological morphology of the skin tissue. Immunohistochemical staining and immunoblotting assay were used to detect the protein expressions of Notch1 and Hes1 in skin tissues. RESULTS Compared with the MC group， both the UA-L group and UA-H group exhibited significantly lower dermatitis scores， along with varying degrees of reduction in histopathological skin damage such as inflammatory cell infiltration. Additionally， the levels of IL-6 and IL-17 in serum and skin tissues were markedly decreased， while the levels of IL-10 were significantly increased in both groups； protein expressions of Notch1 and Hes1 were decreased significantly （P＜0.05）， and the improvements in the aforementioned indicators were more significant in the UA-H group （P＜0.05）. Jagged1 could significantly weaken the improvement effects of UA-H on the above indicators （P＜0.05）. CONCLUSIONS Ursolic acid may attenuate the expression of pro-inflammatory cytokines and enhance the expression of anti-inflammatory factors by blocking Notch1/Hes1 signaling pathway， thereby improving dermatitis symptoms in ACD rats.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:This study aims to obtain the prevalence and features associated with Violence Against Children (VAC) in China and, thus, formulate a prevention strategy.Methods:The mortality-related data of VAC was sourced from the National Disease Surveillance Points System (DSP) during 2013-2021. We analyzed the DSP data regarding children aged 0-17 years old who died from violence. The hospital cases of VAC was sourced from the National Injury Surveillance System (NISS), 2013-2021. We analyzed the data from NISS with the parameter of "intentional injury" caused by VAC in children aged between 0-17 years. Using robust linear regression, we analyze the time trend in the proportion of violence incidence. To understand the variations in the incidence of different types of violence across genders, we apply the chi-square test and adjusted Pearson residuals.Results:The overall trend of death caused by VAC has declined; it was reduced to 0.14/100 000 in 2021 from 0.33/100 000 in 2013. In 2021, male VAC mortality (0.15/100 000) was higher than females (0.13/100 000). The proportion of VAC cases to all injury cases has declined from 3.34% in 2013 to 2.29% in 2021. Among 9 344 VAC cases supervised by hospitals in 2021, the number of males (7 503 cases) was around 4 times that of females (1 841 cases), and the top three modes of violence were blunt tools (64.77%), falls (7.46%) and sharp instruments (6.18%), and 45 cases of sexual violence included 38 girls and 7 boys.Conclusions:The declining death rate due to VAC may be related to the benign development of Chinese society. Prevention strategies targeting training in parenting skills and problem-solving should be prioritized.

Objective To explore the application value of echocardiography in the differential diagnosis of transthyretin cardiac amyloidosis(ATTR-CA)and immunoglobulin light chain cardiac amyloidosis(AL-CA).Methods We conducted a retrospective analysis of echocardiographic parameters of 50 confirmed CA patients diagnosed between November 2021 and January 2024 at The First Affiliated Hospital of Xi'an Jiaotong University,including 6 cases of ATTR and 44 cases of AL.Parameters that could potentially distinguish between the two subtypes were selected using t-tests and x2 tests,and the diagnostic capabilities of these parameters for the two subtypes were analyzed using receiver operating characteristic(ROC)curves.Results There were no statistically significant differences in general characteristics,global longitudinal strain(GLS),ratio of apical to basal strain,ejection fraction to GLS ratio(EFSR),maximum thickness of left ventricular myocardium,relative thickness of left ventricular wall,presence of thickened atrioventricular valves,or presence of enlarged atria between ATTR and AL groups(P＞0.05).The interventricular septal thickness was greater than in ATTR group than in AL group(P＜0.05),and the E/e'ratio(ratio of spectral Doppler early diastolic peak velocity to tissue Doppler early diastolic peak velocity)was greater in ATTR group than in AL group(P＜0.05).ROC curve analysis showed that the areas under the curve for distinguishing between the two subtypes based on interventricular septal thickness and E/e'ratio were 0.891(95％CI:0.792-0.991)and 0.826(95％CI:0.698-0.955),respectively,with a sensitivity of 100.00％and specificity of 95.24％for combined diagnosis.Conclusion Echocardiographic parameters,including E/e'ratio and interventricular septal thickness,may have clinical significance in distinguishing between the two main subtypes of CA in patients.

ObjectiveTo evaluate the effectiveness and safety of Qiaoqi Formula （翘芪组方） for mild influenza. MethodsA randomized controlled study was designed， recruiting 74 patients with mild influenza， who were randomly divided into trial group and control group. The trial group took Qiaoqi Formula orally， 40ml each time， twice a day； the control group took Lianhua Qingwen Capsules （连花清瘟胶囊） orally， 1.4 g each time， three times a day. Both groups were treated for 3 consecutive days and follow-up for 4 consecutive days after treatment. The time for fever reduction including onset of fever reduction， complete fever reduction time， fever reduction rates at 24， 48 and 72 hours， improvement of influenza symptoms， total traditional Chinese medicine （TCM） symptom score， and safety indicators in two groups after treatment were recorded. ResultsSixty-five patients were ultimately included， including 36 in the trial group and 29 in the control group. Onset time of fever reduction in the trial group was （15.49±23.47） h， the complete fever reduction time （21.37±30.06）h， and the 24 h， 48 h， 72 h， fever reduction rate was 77.14%， 88.57%， 91.42% respectively. The above indicators of the control group showed as （17.58±20.38）h， （24.30±21.87）h， 61.29%， 90.32%， 96.77% respectively， with no statistically significant differences （P＞0.05）. On the 7th day after treatment， the total score of TCM syndromes in trial group and control group decreased compared to those before treatment （P＜0.05）. There was no statistically significant difference in the cure rate， significant effective rate， effective rate， and total effective rate of TCM syndromes between groups （P＞0.05）. On the 4th day， the lymphocyte ratio of patients in the control group was higher than before treatment， while alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， urea， and creatinine of both groups before and after treatment were within the normal range. The main adverse reactions in both groups were mild headache and dizziness， and no serious adverse reactions observed. ConclusionThe therapeutic effect of Qiaoqi Formula in treating mild influenza is equivalent to Lianhua Qingwen Capsules， which can shorten the fever reduction time， improve clinical symptoms， and no adverse events observed during the study.

Objective:To construct a column-line diagram diagnostic model based on serum and joint fluid inflammatory markers for the diagnosis of periprosthetic joint infections (PJI) after joint arthroplasty and to validate its predictive ability.Methods:The clinical data of 181 patients diagnosed with PJI or aseptic loosening in the Department of Orthopedics of the First Affiliated Hospital of Chongqing Medical University from January 2015 to June 2020 were retrospectively collected as a modeling group. The best indicators for diagnosing PJI were screened by lasso regression, single-factor and multifactor analysis. By comprehensively considering the weights and intrinsic connections of the indicators, a column-line diagram diagnostic model was constructed and used to develop a clinical decision support system (CDSS). Prospectively, the clinical data of patients diagnosed with PJI or aseptic loosening in the Department of Orthopedics of the First Hospital of Chongqing Medical University from July 2020 to December 2022 were collected as a validation group, and the diagnostic performance of the column-line diagram model was externally validated by methods such as receiver operating characteristic curve (ROC).Results:There were 85 cases of PJI in the 181 cases modeling group and 23 cases of PJI in the 49 cases validation group. Among the 27 potential factors analyzed by lasso regression analysis, body mass index (BMI), blood tests including platelet (PLT), absolute lymphocyte value, interferon γ (IFN-γ), ESR, IL-6, C-reactive protein, D-dimer, and joint fluid tests including C-reactive protein, IL-1, IL-4, IL-6, percentage of multinucleated neutrophils (PMN%), and CD64 may be potential indicators for the diagnosis of PJI. Univariate found significant differences between hematologic tests including sedimentation, C-reactive protein, IL-6, D-dimer and joint fluid tests including C-reactive protein, joint fluid CD64 index, C-reactive protein, IL-1, IL-4, IL-6, PMN%( P<0.05). Further multifactorial regression analysis screened serum IL-6, D-dimer, joint fluid CD64 index, C-reactive protein, IL-1, IL-4, IL-6, and percentage of multinucleated neutrophils, and based on that, the column-line graph model and CDSS system were constructed. The area under the ROC in the validation group was 0.978, and the AUC in the internal validation was 0.995; the C-index of the calibration curve was 99.50%, and the C-index of the internal validation was 99.53%, suggesting that the column-line diagram model has a good predictive ability. Conclusions:The column-line diagram for diagnosing PJI based on multiple diagnostic indicators showed good diagnostic performance. The CDSS system constructed by column-line diagrams could assist clinicians in diagnosing PJI and making reasonable strategies in time.

Thalamocortical circuitry has a substantial impact on emotion and cognition.Previous studies have demonstrated alterations in thalamocortical functional connectivity(FC),characterized by region-dependent hypo-or hyper-connectivity,among individuals with major depressive disorder(MDD).However,the dynamical reconfiguration of the thalamocortical system over time and potential abnormalities in dynamic thalamocortical connectivity associated with MDD remain unclear.Hence,we analyzed dynamic FC(dFC)between ten thalamic subregions and seven cortical subnetworks from resting-state functional magnetic resonance images of 48 patients with MDD and 57 healthy controls(HCs)to investigate time-varying changes in thalamocortical FC in patients with MDD.Moreover,dynamic laterality analysis was conducted to examine the changes in functional lateralization of the thalamocortical system over time.Correlations between the dynamic measures of thalamocortical FC and clinical assessment were also calculated.We identified four dynamic states of thalamocortical circuitry wherein patients with MDD exhibited decreased fractional time and reduced transitions within a negative connectivity state that showed strong correlations with primary cortical networks,compared with the HCs.In addition,MDD patients also exhibited increased fluctuations in functional laterality in the thalamocortical system across the scan duration.The thalamo-subnetwork analysis unveiled abnormal dFC variability involving higher-order cortical networks in the MDD cohort.Significant correlations were found between increased dFC variability with dorsal attention and default mode networks and the severity of symptoms.Our study comprehensively investigated the pattern of alteration of the thalamocortical dFC in MDD patients.The heterogeneous alterations of dFC between the thalamus and both primary and higher-order cortical networks may help characterize the deficits of sensory and cognitive processing in MDD.
