ObjectiveThis paper aims to investigate the protective effects of the Tanyu Tongzhi Youhua prescription（TYTZP） against myocardial ischemia/reperfusion injury in rats via regulation of the cyclic GMP-AMP synthase （cGAS）/stimulator of interferon genes （STING） signaling pathway. MethodsFifty-six 8-week-old male Sprague-Dawley （SD） rats were randomly divided into sham group， model group， ticagrelor group （32.4 mg·kg^-1）， RU320521 （RU.521cGAS inhibitors） group （5 mL·kg^-1）， groups of TYTZP with low dose （3.6 g·kg^-1）， medium dose （7.2 g·kg^-1）， and high dose （14.4 g·kg^-1）， with eight rats per group. The ticagrelor group and groups of TYTZP with different doses received pre-treatment for seven days according to their respective protocols. The RU.521 group received an intraperitoneal injection one hour before modeling. A rat model of the no-reflow phenomenon in myocardial ischemia/reperfusion injury was established by ligating the left anterior descending coronary artery in situ. Myocardial no-reflow area was determined by thioflavin staining. Histopathological morphology of myocardial tissue was observed via hematoxylin and eosin （HE） staining. Cardiac function was detected by echocardiography. Myocardial microcirculation function change was observed by using real-time myocardial contrast echocardiography. The myocardial enzyme levels in the serum were measured by serum biochemical analysis. The double-stranded DNA （dsDNA） levels were detected by using PicoGreen. The protein expression of cGAS， STING， and nuclear factor-κB （NF-κB） p65 in myocardial tissue was detected by Western blot. The levels of cardiac troponin Ⅰ （cTNⅠ）， cardiac troponin T （cTNT）， interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α） in the peripheral blood were measured by enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the sham group， the model group showed a significantly increased myocardial no-reflow area （P<0.01）. Myocardial fiber rupture and disarray and inflammatory cell infiltration were observed by HE staining. The ultrasound results indicated that left ventricular ejection fraction （LVEF） and left ventricular fractional shortening （LVFS） （P<0.01） were significantly decreased. Real-time myocardial contrast echocardiography showed that the peak time of myocardial blood perfusion was significantly prolonged （P<0.01）， and the levels of creatine kinase （CK）， creatine kinase isoenzyme （CK-MB）， lactate dehydrogenase （LDH）， cTNⅠ， cTNT， and dsDNA were significantly elevated （P<0.01）. Western blot results showed that the myocardial protein expressions of cGAS， STING， and NF-κB p65 were upregulated （P<0.01）. ELISA results showed that the inflammatory factors in the serum such as IL-6， IL-1β， and TNF-α were increased （P<0.01）. Compared with the model group， the group of the TYTZP significantly reduced the levels of myocardial enzyme， troponins， and dsDNA （P<0.01， P<0.05）， improved cardiac function and myocardial microcirculation， alleviated histopathological morphology and inflammatory infiltration， inhibited activation of the cGAS/STING pathway， reduced the expression of NF-κB p65 （P<0.01， P<0.05）， and inhibited inflammatory response. ConclusionThe TYTZP mitigates the no-reflow phenomenon in myocardial ischemia/reperfusion injury， and its mechanism is associated with inhibiting the activation of the cGAS/STING pathway and attenuating inflammatory responses.

ObjectiveTo investigate the current status of HIV-related health service uptake among cross-border couples (Chinese husbands and Myanmar wives) in Dehong Dai and Jingpo Autonomous Prefecture (hereinafter referred to as Dehong Prefecture), and to provide evidence for optimizing HIV prevention and control strategies in border areas. MethodsA cross-sectional survey was conducted from September 2022 to September 2023 among 14 662 cross-border couples (Chinese husbands and Myanmar wives) in Dehong Prefecture. Data on sociodemographic characteristics, HIV/AIDS knowledge awareness, and utilization of HIV-related health services within the past year were collected. Multivariable logistic regression was used to analyze factors associated with HIV testing uptake among husbands and wives. ResultsA total of 29 324 individuals (14 662 couples) were included. The overall awareness rate of HIV/AIDS was 82.09%, with the rate among husbands significantly higher than that among wives (85.17% vs. 79.01%, P<0.001). Overall, 94.98% of participants had received at least one HIV-related health service, and the HIV testing rate in the past year was 65.52%. Multivariable logistic regression analysis showed that, compared with participants married for 0‒3 years, those married for 4‒10 years and ≥11 years were more likely to have received HIV testing. The corresponding ORs were 1.344 (95%CI: 1.187‒1.521) and 1.381 (95%CI: 1.211‒1.574) among husbands, and 1.308 (95%CI: 1.155‒1.481) and 1.344 (95%CI: 1.178‒1.533) among wives, respectively. Compared with those holding a marriage certificate, those possessing a border marriage registration certificate were positively associated with HIV testing uptake, with ORs of 1.710 (95%CI: 1.575‒1.857) among husbands and 1.700 (95%CI: 1.565‒1.847) among wives. Compared with illiterate participants, those with primary school education showed lower testing rates, with ORs of 0.738 (95%CI: 0.650‒0.837) among husbands and 0.827 (95%CI: 0.766‒0.891) among wives. Additionally, a history of sexually transmitted diseases (OR=3.656, 95%CI: 1.243‒15.589) and participation in the New Rural Cooperative Medical Scheme (OR=1.51, 95%CI: 1.179‒1.935) were independently associated with higher testing rates among husbands. ConclusionThe overall utilization of HIV-related health services among cross-border couples in Dehong Prefecture is satisfactory, but significant gender disparities exist, with foreign wives showing lower rates of knowledge awareness and lower proportions obtaining such knowledge through certain channels compared with their Chinese husbands. Couples with shorter marriage duration, those with primary school education, and those not included in the border marriage registration system are vulnerable groups with lower HIV testing uptake. Future interventions should prioritize cross-border marriage families at the early stage of entry and in the newly married period. Based on the border marriage registration management system and primary healthcare networks, health education and HIV testing services targeting foreign spouses should be strengthened to improve service accessibility and equity.

Objective·To investigate the longitudinal changes in amygdala and hippocampal subfield volumes before and after transcranial magnetic stimulation(TMS)treatment in patients with major depressive disorder(MDD)and explore their correlation with the antidepressant and anxiolytic efficacy of TMS.Methods·A total of 58 patients diagnosed with MDD at Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,were included in this study between January 2018 and August 2023.Clinical depressive and anxiety symptoms were assessed by using the Hamilton Depression Scale(HAMD),Montgomery-Asberg Depression Rating Scale(MADRS),and Hamilton Anxiety Scale(HAMA)at baseline and post-TMS treatment.Patients underwent a baseline magnetic resonance imaging(MRI)scan followed by TMS treatment targeting the left dorsolateral prefrontal cortex(DLPFC)at a frequency of 10 Hz,totaling 20 sessions.A follow-up MRI scan was conducted on the same day the TMS treatment concluded.Amygdala and hippocampal subfield volumes were segmented and calculated by using FreeSurfer v6.0.0 software.Longitudinal changes in the subfield volumes were analyzed with two-way analysis of variance.Controlling for age,sex,and intracranial volume,partial correlation analysis was conducted between subfield volumes and baseline clinical scores.The association between the rate of volume change in brain regions with significant volume changes and symptom improvement(reduction in HAMD,MADRS,and HAMA scores)was evaluated.Results·Following TMS treatment,a significant increase in the volume of the right amygdala central nucleus was observed(t=-2.441,P=0.018).While the volumes of bilateral hippocampal fimbria decreased,the volumes of most hippocampal subfield and the total hippocampus increased(P<0.05).No significant correlations were found between baseline amygdala or hippocampal subfield volumes and clinical depressive and anxiety symptoms.However,only in patients who responded effectively to TMS treatment,a positive correlation was found between the volume change rate of the left hippocampal tail and reductions in anxiety symptoms(HAMA:r=0.334,P=0.044).Conclusion·High-frequency TMS targeting the left DLPFC may induce volume increases in the right amygdala central nucleus and specific hippocampal subfields.Additionally,the volume change rate of the left hippocampal tail is associated with anti-anxiety effects in TMS responders,suggesting that high-frequency TMS targeting the left DLPFC may induce neuroplastic changes in the central nucleus of the right amygdala and key subfields of the hippocampus.

Objective:To explore the morphological characteristics of the corpus callosum (CC) in patients with unilateral medial temporal lobe epilepsy (mTLE) with hippocampal sclerosis (HS), and their correlation with hippocampal volume and clinical indicators.Methods:This was a cross-sectional study. Clinical (age of onset, disease duration, seizure frequency, seizure duration, etc.) and imaging data of 44 patients mTLE with unilateral HS confirmed by postoperative pathology and 42 healthy controls (HCs) recruited at West China Hospital of Sichuan University from June 2017 to May 2023 were analyzed retrospectively. Among the 44 patients, 19 had left-sided HS and 25 had right-sided HS. All subjects underwent high-resolution 3D T 1WI. Hippocampal volumes were obtained using FreeSurfer. ART was used to measure the morphological parameters of the CC for each participant, including total CC area, volume, perimeter, length, thickness, circularity, and the area of seven CC subregions defined by Witelson: rostrum, genu, body, anterior midbody, posterior midbody, isthmus and splenium. Differences in these metrics between two or three groups were compared using independent samples t-test or one-way ANOVA. Pearson or Spearman correlation analysis was used to observe the correlation between morphological features of the CC and hippocampal volume and other clinical indicators in patients with mTLE with unilateral HS. Results:Compared with HCs, patients with mTLE with unilateral HS had significantly reduced total CC area, CC circularity, as well as the area and thickness of the genu, anterior midbody, posterior midbody, isthmus, splenium, and the area of the rostrum ( P<0.05). Significant differences were observed in the total area, circularity, and subregional areas (genu, rostrum, anterior midbody, posterior midbody, splenium), as well as thickness (genu, anterior midbody, posterior midbody, isthmus) of the CC among mTLE with left-sided HS, mTLE with right-sided HS, and HCs ( P<0.05). When compared to HCs, the total area of the CC, circularity and the areas of the genu, rostrum, anterior midbody, posterior midbody, and splenium, and the thicknesses of the genu, anterior midbody, posterior midbody, and isthmus of the CC were significantly reduced in patients with mTLE with right-sided HS ( P<0.05), and the thicknesses of the midbody and isthmus of the CC were significantly reduced in patients with mTLE with left-sided HS compared to HCs ( P<0.05), and the two-by-two comparison of the rest of the indicators did not show statistically significant differences ( P>0.05). Correlation analysis showed that some morphological abnormalities in the CC in mTLE with unilateral HS patients were significantly correlated with age of onset, disease duration, seizure frequency, seizure duration, and hippocampal volume. Conclusions:mTLE with unilateral HS patients can exhibit morphological abnormalities in the CC, particularly in those with right-sided lesions. These abnormalities are significantly associated with seizure-related factors and hippocampal atrophy.

Objective To investigate the mechanism of Wenjing Decoction in treating endometriosis(EMT)using bioinformatics methods and in vitro experiments.Methods The active components and corresponding targets of Wenjing Decoction were obtained from the TCMSP database,while EMT-related targets were identified using the GEO database.Functional enrichment analysis was conducted on the targets to predict core targets for treating EMT with Wenjing Decoction.Molecular docking was performed on core targets-drug ligands,and in vitro experiments validated the findings.Results Through screening the TCMSP database,117 active components of Wenjing Decoction were identified,corresponding to 248 targets;5 312 EMT-related differential genes were gathered from GEO database,identifying 97 potential targets of Wenjing Decoction for treating EMT,with core targets being IL6,TNF and EGFR.Functional enrichment analysis of EMT differential genes showed enrichment in pathways such as neuroactive ligand-receptor interaction,MAPK signaling pathway,endocytosis,calcium signaling pathway,autophagy and PI3K-Akt signaling pathway.Molecular docking showed that IL6,TNF,EGFR bind stably to their corresponding drug ligands.In vitro experiments indicated that Wenjing Decoction could inhibit the PI3K/Akt/mTOR pathway,promote LC3 Ⅰ to LC3 Ⅱ conversion,enhance the expression of Beclin-1,and reduce P62 expression.Moreover,Wenjing Decoction could hinder the expression of the endometriosis-specific biomarker CA125,decrease EGFR,IL-6 and TNF-α expressions in ectopic endothelial cells,inhibiting proliferation.Conclusion Wenjing Decoction can treat EMT through multiple pathways and targets,with the key mechanism being the reversal of autophagy inhibition via down-regulating of the PI3K/Akt/mTOR pathway.

Objective:To investigate the risk factors associated with 90-day mortality in critically ill patients receiving continuous renal replacement therapy (CRRT), with a particular focus on the association between hypotension within the first hour of CRRT initiation and 90-day mortality after hospital admission.Methods:This study was a post hoc analysis of a prospective cohort study investigating the impact of colloid versus crystalloid priming solutions on early hemodynamics in critically ill patients undergoing CRRT. The study enrolled intensive care unit patients who received CRRT at West China Hospital of Sichuan University from January 2024 to May 2024. The data were collected including demographic characteristics, laboratory tests, CRRT-related parameters, blood pressure, heart rate, sequential organ failure assessment scores, and vasoactive-inotropic score, etc. The 90-day survival outcome after hospital admission of critically ill patients aged 18-80 years who received continuous veno-venous hemodiafiltration was used as the primary outcome indicator. A Cox proportional hazards model analysis was conducted, and the predictive ability of the model was evaluated along with the test of the proportional hazards assumption. The risk factors associated with the 90-day mortality after hospital admission of critically ill patients receiving CRRT were explored, with a particular focus on whether hypotension occurring within the first hour of CRRT initiation was one of these risk factors.Results:A total of 208 patients were included in this study. Within 90 days after hospital admission, 141 patients (67.8%) died, among whom 102 were male (72.3%) and the median age was 61.0 (50.0, 71.5) years; 67 patients (32.2%) survived, among whom 53 were males (79.1%) and the median age was 56.0 (47.0, 68.0) years. The incidence of hypotension within the first hour of CRRT initiation was significantly higher in the death group than in the survival group [29.8% (42/141) vs. 16.4% (11/67), χ2=4.275, P=0.039]. Moreover, The mortality rate of the group with hypotension within the first hour of CRRT initiation was higher than that of the group without hypotension [79.2% (42/53) vs. 63.9% (99/155), χ2=4.275, P=0.039]. The Kaplan-Meier survival analysis showed that the median survival time of patients without hypotension within the first hour of CRRT initiation [39.0 d (95% CI 23.2-54.8)] was longer than that of patients with hypotension [26.0 d (95% CI 18.9-33.1)], and the 90-day cumulative survival rate after hospital admission of patients without hypotension was significantly higher than that of patients with hypotension (Log-rank test, χ2=5.100, P=0.024). Univariate and multivariate Cox proportional hazards analyses demonstrated that serum albumin ( HR=0.964, 95% CI 0.933-0.997, P=0.030), sequential organ failure assessment score ( HR=1.064, 95% CI 1.012-1.118, P=0.015), and the use of mechanical ventilation ( HR=8.272, 95% CI 1.145-59.743, P=0.036) were significantly associated with 90-day mortality in critically ill patients undergoing CRRT. In contrast, the vasoactive-inotropic score ( HR=1.004, 95% CI 0.999-1.008, P=0.079) and the presence of hypotension within the first hour of CRRT initiation ( HR=1.236, 95% CI 0.833-1.835, P=0.293) were not significantly associated with 90-day mortality in critically ill patients undergoing CRRT. The consistency index of this model was 0.654 (95% CI 0.617-0.691), the area under the receiver operating characteristic curve was 0.724 (95% CI 0.658-0.800), and the calibration curve showed that the predicted values of the model were well fitted to the actual observations, suggesting that the predictive effect of this model was relatively ideal. Conclusions:In critically ill patients undergoing CRRT, the occurrence of hypotension within the first hour of CRRT initiation was not significantly associated with 90-day mortality after hospital admission. Lower serum albumin levels, higher sequential organ failure assessment scores, and the use of mechanical ventilation may be the risk factors for 90-day mortality in this population.
