ObjectiveTo observe the effects of Xiaoyaosan on glucagon-like peptide-1 （GLP-1）/GLP-1 receptor （GLP-1r） and protein kinase A （PKA）/cAMP response element binding protein （CREB）/brain-derived neurotrophic factor （BDNF） signaling pathways in the hippocampal CA1 region of rats under chronic restraint stress （CRS），and to explore the mechanism of this formula to alleviate anxiety and depression-like behaviors. Methods40 specific pathogen-free male Sprague-Dawley （SD） rats were randomly divided into normal，model，Xiaoyaosan，and fluoxetine groups，with 10 rats in each group. CRS was used to induce anxiety and depression-like behaviors. The rats in the Xiaoyaosan group were gavaged with aqueous solution of traditional Chinese medicine formula granules （7.36 g·kg^-1·d^-1），while those in the fluoxetine group were gavaged with aqueous solution of fluoxetine （2 mg·kg^-1·d^-1）. Body weight was measured on days 0，7，14，and 21 of the experiment. On days 0 and 22 of the experiment，the sucrose preference test （SPT），forced swimming test （FST），and open field test （OFT） were performed. The pathological morphology of the hippocampal CA1 region was observed by Nissl staining. The relative mRNA expression of post-synaptic density protein-95 （PSD95） and synapsin （SYP） was detected by reverse transcription quantitative real-time polymerase chain reaction. Immunohistochemistry and Western blot were used to detect expression of proteins in the GLP-1/GLP-1r and PKA/CREB/BDNF pathways in the hippocampal CA1 region. ResultsAfter CRS modeling，compared with the normal group，the rats of the model group had anxiety and depression-like behavioral manifestations，neuronal damage in the hippocampal CA1 region，significantly downregulated expression of synaptic plasticity markers PSD95 and SYP genes （P<0.01），and inhibition of GLP-1/GLP-1r and PKA/CREB/BDNF signaling pathways （P<0.05，P<0.01）. Compared with the model group，the Xiaoyaosan group exhibited alleviated anxiety and depression-like behaviors，reduced neuronal damage in the hippocampal CA1 region， significantly increased expression of PSD95 and SYP genes （P<0.01），and the activation of the GLP-1/GLP-1r and PKA/CREB/BDNF signaling pathways （P<0.05，P<0.01）. ConclusionXiaoyaosan can alleviate anxiety and depression-like behaviors in CRS rats by improving synaptic plasticity in the hippocampal CA1 region. The mechanisms may be related to the activation of the GLP-1/GLP-1r pathway and its mediated PKA/CREB/BDNF signaling pathway by the formula.

BackgroundPatients with colorectal cancer are frequently comorbid with depression， which severely affects the quality of life and treatment compliance， while compromising the efficacy of anticancer treament and prognosis. Current therapeutic strategies still have notable limitations， particularly the lack of systematic and targeted synergistic regimens that integrate oncological management and anti-depressive intervention. It is of great clinical significance to explore a safe and effective new comprehensive intervention protocol and clarify its underlying mechanism of action. ObjectiveTo explore the effectiveness and safety of Shugan Yunpi Decoction in alleviating depressive and anxiety symptoms in colorectal cancer patients with depressive disorder through the PI3K-AKT signaling pathway， in order to provide references for the comprehensive treatment of colorectal cancer and depressive disorder. MethodsThis study was a randomized controlled trial. A total of 106 patients admitted to the Baoding No.1 Hospital of traditional Chinese medicine from November 2023 to July 2025 were enrolled， who met the diagnostic criteria for the Chinese protocol of diagnosis and treatment of colorectal cancer （2023 edition） and the diagnostic criteria for depressive disorder as specified in the Chinese Classification and Diagnostic Criteria of Mental Disease， third edition （CCMD-3）. Patients were divided into the study group and the control group using a random number table， with 53 cases in each group. The control group received conventional chemotherapy combined with traditional Chinese medicine five-element music therapy， while the study group received conventional chemotherapy combined with Shugan Yunpi Decoction therapy. Both groups were treated for 8 weeks. Depressive and anxiety symptoms were assessed using the Hamilton Depression Scale-17 item（HAMD-17） and Hamilton Anxiety Scale （HAMA）， respectively. Western blot protein immunoblotting was used to detect the expression levels of PI3K， AKT， and pAKT. Real-time fluorescence quantitative reverse transcription polymerase chain reaction （qRT-PCR） was used to detect the expression levels of PI3K mRNA and AKT mRNA. Adverse reactions were recorded using a self-designed adverse reaction record form. ResultsRepeated measures analysis of variance showed that the time effects （F=139.336， 234.747）， group effects （F=43.900， 101.266）， and time-group interaction effects （F=13.409， 43.216） for HAMD-17 and HAMA scores in both groups were statistically significant （P<0.01）. After 4 and 8 weeks of treatment， the HAMD-17 and HAMA scores in both groups were lower than those before treatment， with statistically significant differences （P<0.05）. HAMD-17 and HAMA scores in the study group were lower than those in the control group （P<0.05）. The time effects （F=571.356， 309.266， 414.492）， group effects （F=6.901， 26.361， 39.362）， and time-group interaction effects （F=18.592， 19.266， 33.484） for the protein expression levels of PI3K， AKT， and pAKT in both groups were all statistically significant （P<0.01）. After 8 weeks of treatment， the protein expression levels of PI3K and pAKT in the study group were lower than those in the control group， while the AKT protein expression level was higher than that in the control group（P<0.01）. The time effects （F=338.555， 225.059）， group effects （F=5.429， 9.726）， and time-group interaction effects （F=12.953， 21.214） for PI3K mRNA and AKT mRNA expression levels in two groups were all statistically significant （P<0.01）. After 8 weeks of treatment， the expression levels of PI3K mRNA and AKT mRNA in the study group were lower than those in the control group （P<0.05）. The incidence of adverse reactions in the study group was lower than that in the control group （χ²=4.810， P<0.05）. ConclusionShugan Yunpi Decoction may help to ameliorate depressive and anxiety symptoms in colorectal cancer patients with depressive disorder by regulating the PI3K-AKT signaling pathway， decreasing the levels of PI3K， pAKT， PI3K mRNA， and AKT mRNA， with a favorable safety profile. ［Funded by Baoding City Science and Technology Planning Project （number， 2341ZF291）］

Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective Exploring the therapeutic mechanism of Yishen Jiangzhuo Granules(YSJZG)on chronic kidney disease(CKD)based on mitochondrial dynamics and apoptosis of renal tubular epithelial cells.Methods The CKD model of rats with 5/6 nephrectomy was adopted and divided into 6 groups according to random number table:sham operation control group,model group,emodin group(500 mg/kg/d),Yishen Jiangzhuo granule low,middle and high dose groups.After 8 weeks of treatment with YSJZG,serum creatinine(SCR)and urea nitrogen(BUN),pathological changes of renal cortex,mitochondrial morphology and ultrastructure were detected,and mitochondrial kinetic protein in renal tubular epithelial cells was detected by immunohistochemistry(Drp1,Fis1)and fusion proteins(Opa1,Mfn1)were detected by Western blot,and apoptotic proteins(CytC,Bax)in cytoplasm and mitochondria were detected by real-time PCR.Results Renal injury:Compared with the model group,YSJZG groups significantly reduced the levels of SCR and BUN,renal tubular degeneration and necrosis,and mitochondrial structural damage in rats.Renal tubule mitochondrial dynamic protein:Compared with the model group,the expression of division proteins Drp1 and Fis1 was downregulated,the expression of fusion proteins Opa1 and Mfn1 was upregulated,and transmission electron microscopy observed that the mitochondrial fragmentation changes were relatively mild.Apoptosis related indicators and mtDNA copy number of renal tubular cells:Compared with the model group,the content of Bax protein in renal tubular epithelial cells of YSJZG groups increased significantly in cytoplasm(P<0.05)and decreased significantly in mitochondria(P<0.05).The content of CytC protein decreased significantly in cytoplasm(P<0.05)and increased significantly in mitochondria(P<0.05).The copy number of mtDNA increased significantly(P<0.05),and the total levels of SMAC,CytC and Bax mRNA decreased significantly(P<0.05).Correlation between mitochondrial dynamic protein and apoptosis in renal tubular cells:Pearson correlation analysis showed that the expression of Drp1 and Fis1 was negatively correlated with the expression of CytC in mitochondria,and positively correlated with the expression of CytC in cytoplasm.The expression levels of fusion proteins Opa1 and Mfn1 showed a significant positive correlation with CytC expression in mitochondria,and a significant negative correlation with CytC expression in cytoplasm.Conclusion YSJZG can significantly delay the progression of CKD,and its mechanism may be achieved by regulating mitochondrial dynamics of renal tubular epithelial cells,thereby inhibiting endogenous cell apoptosis pathway.

Objective:To study the diagnostic value and correlation of contrast-enhanced ultrasound time-intensity curve in the main pathological features of cervical cancer.Methods:From August 2021 to August 2023, 100 patients with cervical cancer and 100 patients with benign cervical tumors examined in Dingzhou People’s Hospital were selected for study. Patients with benign cervical tumors were included in the control group, and patients with cervical cancer were included in the observation group.The two groups of patients were examined by PHILIPS EPIQ7 C color Doppler ultrasound diagnostic instrument and PHILIPS EPIQ5 color Doppler ultrasound diagnostic instrument to obtain the quantitative parameters of the time-intensity curve of the two groups. The bivariate Spearman correlation test was used to analyze the main pathological features of cervical cancer patients (lesion diameter, pathological type, vascular invasion, lymph node metastasis, differentiation degree, clinical stage) and the correlation between radiotherapy and chemotherapy and the acquisition of time-intensity curve. The receiver operating characteristic curve (ROC) was drawn to analyze the diagnostic value of the time-intensity curve.Results:The time to peak (TTP) value of the cervical cancer group was lower than that of the control group, and the peak intensity (PI) and maximum peak intensity ratio (PI/PIc) values were higher than those of the control group, the differences were statistically significant ( P<0.05). Compared with patients with non-squamous cell carcinoma, vascular invasion < 1/2, no lymph node metastasis, moderate to high differentiation, stage I-II, and after radiotherapy and chemotherapy, patients with squamous cell carcinoma, vascular invasion ≥ 1/2, lymph node metastasis, low differentiation, stage III-IV, and before radiotherapy and chemotherapy had lower TTP values, higher PI and PI/PIc values, and the differences were statistically significant ( P<0.05). Pathological type, vascular invasion, lymph node metastasis, differentiation degree and clinical stage were negatively correlated with TTP, and positively correlated with PI and PI/PIc ( P<0.05) .Chemoradiotherapy was positively correlated with TTP, and negatively correlated with PI and PI/PIc ( P<0.05). The sensitivity and specificity of combined detection of time intensity curve were higher than those of TTP, PI, PI/Ic, area under curve (AUCTC) and mean transit time (MTT), and the differences were statistically significant ( P<0.05). The AUC values of combined detection of TTP, PI, PI/PIc and time intensity curve were all > 0.85, and the diagnostic value was high. Conclusions:The time-intensity curve of contrast-enhanced ultrasound is closely related to the main pathological features of cervical cancer, such as pathological type, lymph node metastasis and staging. According to the changes, the effect of radiotherapy and chemotherapy can be judged, which can provide a good reference for the diagnosis and treatment of cervical cancer.

Purpose To investigate the clinical and pathological characteristics of synchronous multiple primary malignancy(sMPM)with lymphoid hematopoietic tissue tumors.Methods A retrospective analysis was conducted on the clinical and pathological data of 20 cases of sMPM associated with lymphoma.Immunohistochemistry using the En-Vision two-step method was performed to detect the expression of relevant proteins,while FISH and next-generation se-quencing technologies were used to identify gene mutations.Relevant literature was also reviewed.Results There were 14 females and 6 males,aged from 30 to 75 years(median 67 years).All of them manifested as solid organ mas-ses complicated by lymphadenopathy.Lymphohematopoietic tissue tumors consisted of:7 cases of Hodgkin lymphoma(6 cases of classic Hodgkin lymphoma,1 case of nodular lymphocyte predominant Hodgkin lymphoma),13 cases of non-Hodgkin lymphoma(4 cases of Follicular lymphoma,2 cases of small lymphocytic lymphoma/chronic lymphocytic leukemia,2 cases of diffuse large B-cell lymphoma,1 case of plasmablastic plasmacytoma,1 case of marginal zone B-cell lymphoma,1 case of B-lymphoblastic lymphoma,2 cases of peripheral T-cell lymphoma,NOS).Solid tumors con-sisted of:9 cases of papillary thyroid carcinoma,1 case of medullary thyroid carcinoma,2 cases of adenocarcinoma of the lung,2 cases of gallbladder adenocarcinoma,2 cases of invasive carcinoma of the breast,2 cases of gastrointestinal adenocarcinoma,1 case of pleomorphic undifferentiated sarcoma of the lower extremity,and 1 case of oropharyngeal squamous cell carcinoma.17 patients underwent surgical resection,and 3 patients were diagnosed by core needle biop-sy or excision biopsy.10 cases of lymphoma involved in the lymph nodes of the tumor drainage area,and 10 cases were found to have lymph node involvement in other areas by imaging examination.Among the 5 cases analyzed by targeted next generation sequencing,no revelent genetic changes were founded,and no germline mutations or chromosomal kar-yotype abnormalities were founded.Based on the tumor types,patients received varying degrees of radiotherapy,chem-otherapy,or follow-up.Follow-up information was available in all cases and ranged from 5 to 96 months,15 were sur-vived and four patients died of the tumor,and 1 case was lost to follow-up.Conclusion MPMs with lymphoid hemato-poietic tissue tumors are rare,clinicians and pathologists should be careful to avoid missing the diagnosis of lymphoma.

Objective To explore the molecular mechanism of cerebroprotein hydrolysate-1(CH-1)in improving cognitive impairment of VD at animal level,and to determine the regulatory effect of CH-1 on Nrf2/ARE signaling pathway.Methods Thirty-six SD rats were randomly divided into sham operation group,VD group,low-and high-dose groups,with 9 rats in each group.VD model was established by bilateral common carotid artery ligation,and CH-1 was injected intraperitone-ally for 3 weeks.Morris water maze test and new object recognition test were performed to evalu-ate cognitive function.Hippocampal tissues was collected for immunohistochemistry/Western blot analysis.Results Compared with the sham operation group,the VD group exhibited significantly prolonged escape latency at 2-4 d of Morris water maze test,and up-regulated expression of ubiquitinated protein,LC3 Ⅱ/Ⅰ ratio,P65 and Beclin1 protein in the hippocampus,while down-regulated P62 expression(P＜0.05).Obviously shortened escape latency was observed in the high-dose group at 3-4 d and the low-dose group at 4 d than the VD group(P＜0.05).The resi-dence time in target quadrant,number of platform crossings,total exploration time of novel object recognition in the high-dose group and the total exploration time of novel object recognition in the low-dose group were significantly longer than those in VD group(P＜0.05).The expression levels of ubiquitinated,LC3 Ⅱ/Ⅰ ratio,P65 and Beclin1 were significantly lower in the low-dose group and high-dose group than the VD group(P＜0.05).The expression level of P62 protein in the VD group,low-and high-dose group were significantly increased in a dose-dependent manner(2.78±0.44,1.80±0.24 vs 3.67±0.34;2.37±0.26,1.53±0.09 vs 2.92±0.19;2.74±0.14,1.81±0.19 vs 3.93±0.50;2.28±0.17,1.72±0.17 vs 3.17±0.31,P＜0.05).Conclusion CH-1 can effectively improve the cognitive ability of VD rats and reduce the autophagy of hippocampal neurons.This therapeutic effect may be closely related to its enhancing activity of Nrf2/ARE signaling pathway.

Objective:To analyze the effect of continuous positive airway pressure (CPAP) on maternal and neonatal outcomes in pregnant women with obstructive sleep apnea syndrome (OSAS), especially on the incidence of hypertensive disorder in pregnancy (HDP) in women with moderate to severe OSAS.Methods:A total of 180 pregnant women with OSAS who were diagnosed through sleep monitoring during pregnancy due to high-risk factors of OSAS and registered in Peking University People′s Hospital from January 2021 to May 2024 were selected as the study subjects. Clinical data were collected from medical records for retrospective analysis. According to whether they received standardized treatment with CPAP, they were divided into the CPAP treatment group (42 cases) and the control group (138 cases). The CPAP treatment group consisted of 9 pregnant women with moderate to severe OSAS, while the control group consisted of 34 pregnant women with moderate to severe OSAS. The maternal and neonatal outcomes, the incidence of HDP, placental weight after delivery and placental weight/neonatal birth weight ratio were compared between the two groups.Results:(1) The average gestational age of pregnant women in the CPAP treatment group was higher than that in the control group [(38.7±1.0) vs (38.0±1.4) weeks], the proportion of infants small for gestational age (SGA) in the CPAP treatment group was lower [0 (0/42) vs 12.3% (17/138)], and the birth weight of infants in the CPAP treatment group was bigger [(3 396±475) vs (3 082±710) g); the differences between the two groups were statistically significant (all P<0.05). There were no significant differences between the CPAP treatment group and the control group in terms of delivery mode, rates of postpartum hemorrhage and preterm birth, umbilical artery blood gas analysis pH<7.1, lactate≥6.0 mmol/L, base excess<-12.0 mmol/L and the incidence of gestational diabetes mellitus and HDP (all P>0.05). (2) The placental weight of the CPAP treatment group was significantly lower than that of the control group [(554.0±70.6) vs (615.7±119.1) g], the placental weight/newborn birth weight ratio of the CPAP treatment group was significantly lower than that of the control group (median: 0.17 vs 0.19), and the differences were statistically significant (all P<0.05). (3) The incidence of HDP in pregnant women with moderate to severe OSAS in the CPAP treatment group was lower than that in the control group [1/9 vs 61.8% (21/34)], and the difference was statistically significant ( P<0.05). Conclusions:CPAP treatment could prolong the gestational age in pregnant women with OSAS, reduce the incidence of SGA, increase the birth weight of infants, and reduce the incidence of HDP in pregnant women with moderate to severe OSAS, and is worth promoting in clinical practice. The improvement of neonatal outcomes by CPAP treatment is closely related to the placenta, which is worthy of further exploration.

The integration of multi-source data and the establishment of early warning indicator systems constitute pivotal elements for advancing surveillance and early warning capacities in respiratory infectious diseases. Given the multifaceted transmission mechanisms and complex contributing factors inherent in respiratory infectious diseases, surveillance datasets and associated early warning indicators demonstrate notable heterogeneity and sophisticated interrelationships. Furthermore, as surveillance and early warning requirements significantly vary across diverse epidemiological scenarios, accurate assessment of the value and applicability of distinct data types and indicators is imperative. This paper systematically reviews and synthesizes recent advancements in surveillance data and early warning indicators for respiratory infectious diseases, drawing on both domestic and international research. Particular attention is dedicated to analyzing the applicability and efficacy of various data types and indicators within multiple practical contexts, aiming to provide robust theoretical frameworks and methodological guidance to facilitate the development of resilient and efficient surveillance and early warning systems for respiratory infectious diseases.
