ObjectiveTo investigate the effects of Huanglian Jiedutang (HLJDT) on cognitive function in mice with ischemic stroke (IS) and to elucidate whether its neuroprotective effects are mediated by inhibition of the nuclear factor-κB (NF-κB) signaling pathway and subsequent suppression of NF-κB-regulated neuronal apoptosis. MethodsAn IS model was established using middle cerebral artery occlusion (MCAO). Sixty C57BL/6J mice were randomly assigned to five groups (n =12 per group), i.e., sham operation, model, HLJDT low-dose (3.9 g·kg-1·d-1), HLJDT high-dose (7.8 g·kg-1·d-1), and Ginkgo biloba extract (GBE, 31.2 mg·kg-1·d-1). Post-operatively, neurological deficit scores (Longa score), cerebral infarct volume assessed by 2,3,5-triphenyltetrazolium chloride (TTC) staining, and brain water content were evaluated. Learning and memory were assessed using new object recognition (NOR) and fear conditioning (FC) tests. Hippocampal pathology was examined via hematoxylin and eosin (HE) staining. Immunofluorescence detected expression of glial fibrillary acidic protein (GFAP, astrocyte marker), cellular oncogene Fos (c-Fos, neuronal activation marker), and glutamate decarboxylase 65 (GAD65). Western blot measured nuclear factor-κB inhibitor protein α (IκBα), phosphorylated IκBα (p-IκBα), NF-κB p65, phosphorylated NF-κB p65 (p-NF-κB p65), ionic calcium binding adapter molecule 1 (Iba-1), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and apoptosis-related proteins, such as cleaved cysteinyl aspartate-specific protease 3 (Caspase-3), B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax). Real-time quantitative PCR (Real-time PCR) was used to assess mRNA levels of Iba-1, TNF-α, IL-1β, NF-κB p65, cleaved Caspase-3, Bax, and Bcl-2. ResultsCompared with the sham group, the model group exhibited significantly increased neurological deficit scores, brain water content, and cerebral infarct volume (P<0.01). Hippocampal CA1 neurons were disorganized, showing nuclear pyknosis and karyolysis. NOR exploration time and FC freezing time were significantly reduced (P<0.01). GFAP and c-Fos expression were increased, while GAD65 expression was decreased (P<0.01). Cleaved Caspase-3 and Bax were upregulated, Bcl-2 was downregulated, and the Bax/Bcl-2 ratio was elevated (P<0.01). Expression levels of p-IκBα, p-NF-κB p65, IL-1β, TNF-α, and Iba-1 were significantly increased (P<0.01). Compared with the model group, HLJDT high-dose, low-dose, and GBE groups showed significant improvements in all parameters (P<0.01). Among them, the HLJDT high-dose group showed the most pronounced neuronal structural recovery and superior performance in NOR and FC tests (P<0.01). In this group, GFAP and c-Fos decreased, GAD65 increased (P<0.01), apoptosis-related protein expression was reversed, and NF-κB signaling and related inflammatory factor expression were suppressed (P<0.01). ConclusionHLJDT ameliorates cognitive dysfunction in mice after IS, potentially by inhibiting the NF-κB signaling pathway, thereby reducing neuroinflammation and hippocampal neuronal apoptosis.

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 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.

Objective:To explore the potential of integrating virtual surgery with three-dimensional (3D) printed guides in the surgical management of mandibular benign tumors and subsequent reconstruction of bone defects.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent computer-assisted resection and vascularized fibular flap reconstruction for benign mandibular tumors at the Department of Oral and Maxillofacial Surgery, First Affiliated Hospital of Zhengzhou University, from June 2013 to December 2020. According to the utilization of guide plates for mandibular and fibular osteotomy during surgical procedures or not, the patients were categorized into two cohorts: a guide plate cohort and a non-guide plate cohort. In the guide plate group, custom-designed gudie plates based on virtual surgical plans were fabricated using 3D printing technology and employed intraoperatively; In the non-guide plate group, surgery was exclusively performed based on virtual surgical plan and prebent titanium plate without any supplementary plating. The measured outcomes included fibular flap osteotomy, operation duration, and clinical flap survival. Computed tomography images obtained one week post-surgery were utilized to assess the intersegmental commissure degree between fibular segments as well as between fibular segments and mandible, commissure degree between fibular segments and prebent titanium plate, and condyle position. The satisfaction of patients with their facial appearance was evaluated 6 months after the surgery using a visual analogue scale. Statistical analysis was conducted using SPSS 21.0 software. Independent sample t-tests was utilized to compare the duration of operation and and postoperative evaluation of facial appearance, the Chi-square tests was utilized for condyle position, commissure degrees among interactions involving fibular segments, prebent titanium plates, bone segments( P<0.05 denoted statistical significance). Results:A total of 30 patients were enrolled, comprising 17 males and 13 females, with a median age of 24 years (16-64 years). The preparation process of fibular flaps proceeded smoothly. The required length of fibula was measured as (14.1 ± 1.9) cm (5.7-18.1 cm), while the number of fibular segments ranged from 2 to 4, averaging at approximately 2.9 ± 0.6. The mandibular defects were repaired using a single-layer fibula in 12 cases, a vascularized folded fibula in 7 cases and a combination of vascularized and non-vascularized fibula in 11 cases. The operation time for the guide plate group was recorded as ( 335.9 ± 64.0) min (240-433 min), while it was observed to be (470.7 ± 140.5 ) min (280-680 min) for the non-guide plate group.The postoperative follow-up duration ranged from 9 to 23 months, with an average period of 11 months. All fibular flaps demonstrated clinical survival. The number of patients with good commissure degree between fibular and mandibular segments, between prebent titanium plate and fibular and mandibular segments and the position of condyle were 15, 15 and 13 cases in guide plate group, 10, 13 and 11 cases in non-guide plate group respectively. The statistical analysis revealed a significant difference ( P<0.05) in the degree of commissure between the fibular and the mandibular segments (15/15 vs. 10/15) in the two groups. Both groups exhibited high levels of satisfaction regarding their postoperative facial appearance at the 6 months follow-up, observed to be 9.6±0.5 and 9.3±0.5 respectively, and the statisticla analysis revealed non-significant difference ( P>0.05). Conclusion:The integration of virtual surgery with 3D printed guide plates can effectively reduce operative time and improve precision in the repair and reconstruction of free-fibular flaps following resection of benign tumors of the mandible.

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.
