ObjectiveTo investigate the correlation between neutrophil-to-lymphocyte ratio （NLR）， platelet-to-lymphocyte ratio （PLR）， systemic immune-inflammation index （SII） and the severity of intrauterine adhesions （IUA）. MethodsThe retrospective study included 380 patients who underwent transcervical resection of adhesions （TCRA） from December 2019 to March 2025. Based on the American Fertility Society （AFS） classification， patients were divided into mild （n=61）， moderate （n=225）， and severe （n=94） groups. NLR， PLR， and SII were calculated from preoperative blood tests. Statistical analyses included Kruskal-Wallis test and ordinal Logistic regression. ResultsNLR， PLR， and SII were significantly higher in the severe IUA group compared to the mild group （P<0.05）， with SII showing the strongest predictive ability （OR=1.004， P=0.001）. The number of intrauterine procedures was an independent risk factor （OR=1.27/level， P=0.016）. The predictive model ［Logit（P）=-0.676+0.241×operation times+0.004×SII］ effectively identified severe IUA cases. ConclusionInflammatory markers （particularly SII） are correlated with IUA severity and may serve as non-invasive tools for clinical assessment.

ObjectiveTo investigate the inhibitory effect of Biejiajian Pills （BJJW） on the growth of liver cancer， as well as its potential mechanism in mediating the AMP-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR） pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group， BJJW group （2.2 g/kg）， and metformin group （250 mg/kg）， and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment； HE staining was used to observe histopathological changes； the levels of reactive oxygen species （ROS） and adenosine triphosphate （ATP） in tumor tissue were measured； immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups， and the Tukey’s test was used for further comparison between two groups； the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups， and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the model group， the BJJW group had a tumor inhibition rate of 45.73%， with significant reductions in both tumor volume and weight （P<0.01）. Pathological examination showed that compared with the model group， the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group， the BJJW group had a significant increase in ROS level （P<0.001） and a significant reduction in ATP level （P<0.001）， as well as significant increases in p-AMPK/AMPK ratio （0.81±0.20 vs 0.13±0.04， P<0.01） and p-ULK1/ULK1 ratio （0.69±0.17 vs 0.18±0.13， P<0.01） and a significant reduction in p-mTOR/mTOR ratio （1.34±0.16 vs 3.20±0.62， P<0.01）. ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction， increasing the level of ROS， reducing the level of ATP， and activating the AMPK/mTOR signaling pathway.

Objective: To explore the latent profile characteristics of regulatory emotional self-efficacy and its relationship with non-suicidal self-injurious (NSSI) behavior among junior and senior high school students, so as to provide a basis for effectively reducing NSSI behaviors. Methods: From April to October 2023, a total of 1 217 junior and senior high school students were selected from Tongren City, Zunyi City and Qiannan Prefecture of Guizhou Province by stratified cluster random sampling method. The Scale of Regulatory Emotional Self-efficacy and the Adolescent Self-injury Scale were administered. Latent profile analysis (LPA) was employed to explore distinct profiles of regulatory emotional self-efficacy, and the Lanza, Tan, and Bray s method (LTB) was used to analyze the relationship between these profiles and NSSI behavior. Results: The prevalence rate of NSSI behavior among junior and senior high school students was 28.6%. Among males, regulatory emotional self-efficacy was categorized into two types: moderate positive expression-low negative management group (59.1%, n =353) and high efficacy group (40.9%, n =244); among females, regulatory emotional self-efficacy was classified into three categories: low efficacy group (18.4%, n =114), high positive expression-low negative management group (56.3%, n =349), and high efficacy group (25.3%, n =157). There were statistically significant differences in total NSSI scores across different potential categories of regulatory emotional self-efficacy within both males and females ( Z/H = -5.75 , 57.58, both P <0.01). The differences in NSSI prevalence rates across the potential categories of regulatory emotional self-efficacy were statistically significant for both males and females ( χ 2=38.00, 69.14, both P <0.01), and among females, the differences in NSSI prevalence rates between the high efficacy group and the low efficacy group ( χ 2=60.01) and between the high efficacy group and the high positive expression-low negative management group ( χ 2=31.34) were also statistically significant (both P < 0.016 7 ). Binary Logistic regression analysis revealed that, compared with the high efficacy group within each gender, the moderate positive expression-low negative management group among males ( OR =2.36), and both the low efficacy group and the high positive expression-low negative management group among females ( OR =6.19, 2.97), were at an increased risk of engaging in NSSI (all P <0.01). Conclusion Different latent profiles of regulatory emotional self efficacy among junior and senior high school students are associated with NSSI behavior.

OBJECTIVE To investigate the risk factors for sodium valproate （VPA）-induced hyperammonemia in neurocritical patients， and to construct a risk prediction model. METHODS Clinical data were retrospectively collected from 172 neurocritical patients who received VPA treatment in the Department of Critical Care Medicine， the Fourth Affiliated Hospital of Soochow University from January 2022 to June 2025. Patients were divided into the hyperammonemia group （73 cases） and the normal group （99 cases） based on their blood ammonia levels. Univariate analysis and LASSO regression analysis were used to screen for predictive variables. Independent factors were identified through multivariate Logistic regression analysis， and a nomogram was constructed accordingly. The performance of the model was evaluated using receiver operating characteristic （ROC） curve， calibration curve， and decision curve analysis （DCA）. RESULTS Combination of univariate analysis and LASSO regression analysis screened out seven predictive variables： body mass index （BMI）≥24.0 kg/m 2 ， concomitant use of benzodiazepines， VPA blood concentration， hemoglobin， serum urea， average daily VPA dose， and albumin. Multivariate Logistic regression analysis showed that concomitant use of benzodiazepines， BMI≥24.0 kg/m 2 ， VPA blood concentration， albumin and serum urea level （with odds ratios of 1.615， 1.538， 1.623， 1.942 and 0.637， respectively； 95% confidence intervals of 1.128-2.359， 1.059-2.251， 1.112-2.431， 1.106-3.598 and 0.402-0.980， respectively） were all significantly associated with VPA-induced hyperammonemia in neurocritical patients （ P ＜0.05）. The nomogram prediction model constructed based on these variables was evaluated， showing that the area under the ROC curve was 0.810 for the test set and 0.844 for the validation set. The calibration curves closely approximated t he actual curves， and the application of this model could improve the clinical net benefit. CONCLUSIONS Concomitant use of benzodiazepines， BMI≥24.0 kg/m 2 ， high VPA blood concentration and high albumin level are independent risk factors for VPA-induced hyperammonemia in neurocritical patients， while high serum urea level is an independent protective factor. The risk prediction model constructed based on these factors exhibits good discrimination， consistency， and clinical applicability， making it applicable for predicting the risk of VPA-induced hyperammonemia in neurocritical patients.

Depression is a common psychiatric disorder characterized by persistent low mood or mental disorders. Current treatments primarily focus on regulating neurotransmitter levels， but their effectiveness is limited. The mechanisms underlying its onset are complex， and there is no unified consensus. Abnormal signaling pathway transmission plays a crucial role in the development of depression， involving multiple pathways， including Toll-like receptor 4/nucleotide-binding oligomerization domain-like receptor protein 3 （TLR4/NLRP3）， nuclear factor-κB （NF-κB）， Janus kinase/signal transducer and activator of transcription （JAK/STAT）， mitogen-activated protein kinase/extracellular signal-regulated kinase （MAPK/ERK）， brain-derived neurotrophic factor/tyrosine kinase receptor B （BDNF/TrkB）， cyclic AMP/protein kinase A/cAMP response element-binding protein （cAMP/PKA/CREB）， and others. Traditional Chinese medicine（TCM） is based on a holistic approach and the principle of treatment based on the differentiation of syndromes， regulating the balance of multiple systems and organ functions from a macroscopic perspective. This approach has shown unique advantages in the treatment of depression. TCM attributes the onset of depression to dysfunction of the organ systems， involving liver Qi stagnation， heart spirit deficiency， kidney essence depletion， and spleen dysfunction. TCM compound treatments focus on soothing the liver， strengthening the spleen， calming the heart， and replenishing essence， with formulas such as Xiaoyaosan， Zishui Qinggan Yin， and Chahu Jia Guizhi Longgu Muli Tang. The active components of Chinese herbs mainly aim to tonify and regulate Qi， such as salidroside， ginsenoside Rb₁， astragaloside， and muscone. External TCM treatments， primarily acupuncture， aim to open the orifices and invigorate the spirit. Acupoints such as Baihui， Shenting， and Yintang are commonly used. Additionally， massage and moxibustion therapy can intervene in depression by regulating signaling pathways. This article reviews the core role of signaling pathways in the development of depression and the mechanism of TCM regulation of signaling pathways to intervene in depression， aiming to discover new therapeutic approaches that can improve the symptoms of depressed patients.

The pathological changes of myocardial infarction （MI） are mainly characterized by progressive myocardial ischemic necrosis， decline in cardiac diastolic function， thinning of the ventricular wall， and enlargement of the ventricles. The clinical manifestations include myocardial ischemia， heart failure， arrhythmia， shock， and even sudden cardiac death， rendering MI one of the most perilous cardiovascular diseases. Currently， the clinical treatment for MI primarily involves interventional procedures and drug therapy. However， due to their significant side effects and high complication rates associated with these treatments， they fail to ensure a satisfactory quality of life and long-term prognosis for patients. On the other hand， traditional Chinese medicine has demonstrated remarkable potential in improving patient prognosis while reducing side effects. Research has elucidated that various signaling pathways such as nuclear transcription factor-κB （NF-κB）， adenosine 5̒-monophosphate-activated protein kinase （AMPK）， transforming growth factor-β （TGF-β）/Smads， mitogen-activated protein kinase （MAPK）， Wnt/β-catenin （β-catenin）， and phosphatidylinositol 3-kinase （PI3K）/protein kinase B（Akt） play crucial roles in regulating the occurrence and development of MI. Effectively modulating these signaling pathways through its therapeutic interventions， traditional Chinese medicine can enhance MI management by inhibiting apoptosis， providing anti-inflammatory properties， alleviating oxidative stress levels， and resisting myocardial ischemia. Due to its notable efficacy and favorable safety， it has become an area of focus in clinical practice.

Objective:To explore the regulation and mechanism of human placental extract(HPE)on lipopolysaccharide(LPS)-induced BV2 microglial cell inflammation.Methods:Microglia cell lines(BV2)were cultured in vitro and divided into PBS group,HPE group,LPS group and LPS+HPE group.BV2 cell viability was measured by CCK-8 analysis.A fluorescent probe targeting reactive oxygen species(ROS)was to detect the level of intracellular ROS.The mRNA levels of TNF-α,IL-1β and IL-6 were detected by RT-qPCR.The supernatants of different treatment groups were collected.The content of nitric oxide(NO)was detected by the Griess method,and the secretion levels of TNF-α,IL-1β and IL-6 were detected by the flow magnetic bead microarray(CBA)method.The indirect contact co-culture system between BV2 and mouse hippocampal neurons cell line HT22 cells was established to evaluate the neurotoxicity of HPE by the assessment of the cell viability and apoptosis of HT22 cells using CCK-8 or flow cytometry.The potential signaling molecules of NF-κB signaling pathway was detected by flow cytometry.Results:Compared with the PBS group,1.2 μg/ml LPS and 50 ng/ml HPE significantly inhibited the activity of BV2 cells.Compared with the PBS group,the mRNA levels of TNF-α,IL-1β and IL-6 in BV2 cells of the LPS group were significantly increased(P<0.05),and the secretion levels of NO,TNF-α,IL-1βand IL-6 in the supernatant were also significantly upregulated(P<0.05).The expressions of related signaling pathway molecules Toll-like receptor 4(TLR4),pIκBα and pNF-κB p65 were significantly increased(P<0.05).Compared with the LPS group,the mRNA levels of TNF-α,IL-1β and IL-6 in BV2 cells,the secretion levels of NO,TNF-α,IL-1β and IL-6,the neurotoxicity and neuronal apoptosis induced by microglial conditional medium,and the expressions of TLR4,pIκBα and pNF-κB p65 in the LPS+HPE group were significantly downregulate(P<0.05).Conclusion:HPE may alleviate the microglial inflammation,possibly through the TLR4/NF-κB signaling pathway.

Purpose To investigate whether concomitant vascular penetration in ground glass nodule(GGN)is a risk factor for progression of pulmonary nodule,and to inform the follow-up strategy of pulmonary GGN.Materials and Methods A retrospective collection of 256 patients who underwent high-resolution CT of the chest and were diagnosed as containing persistent GGN(initial diameter≤10 mm)at the Affiliated Hospital of West Anhui Health Vocational College from January 2016 to November 2023 was performed.The nodules were categorized into the group with pulmonary vascular penetration(group A)and the group without pulmonary vascular penetration(group B)according to whether or not pulmonary vascular penetration was present within the GGN on chest high-resolution CT images.The progression of GGN was judged by evaluating the changes in imaging features such as size and density,and the progression-free survival of the nodules between the two groups was compared.Results Among 256 patients,155 patients(196 GGN)were divided in group A and 101 patients(106 GGN)in group B.During 14 to 80 months period,31 nodules had progressed,and the rate of GGN progression was 10.3%(31/302).Nodes in both groups had the same progression-free survival rate at 1 year of follow-up,and there was a flat decline in progression-free survival rate from 2 to 5 years of follow-up,but the differences in progression-free survival between different follow-up time nodes(36,60 and 80 months)were not statistically significant in either group(χ2=2.880,P=0.090;χ2=1.683,P=0.194;χ2=2.630,P=0.105).Conclusion The presence of pulmonary vascular penetration in pulmonary GGN is a common presentation and is not an independent risk factor for nodule progression,and cannot be used as an indicator of the risk of nodule malignancy and surgical intervention.

Bisphenol A (BPA) is an environmental chemical that is widely exposed in human daily life. It has attracted much attention because of its estrogenic effect. Polycystic ovary syndrome (PCOS) is the most common endocrine metabolic disease in women of reproductive age. Its pathogenesis involves the interaction of genetic, environmental and endocrine disorders. In recent years, more and more studies have shown that BPA plays an important role in the occurrence and development of PCOS. BPA promotes the development of PCOS by interfering with insulin sensitivity, immune response and changing ovarian structure and function. In addition, BPA exposure levels are associated with hyperandrogenism, insulin resistance, obesity, dyslipidemia, and decreased ovarian reserve in PCOS patients. This review summarizes the effects of BPA on PCOS in terms of ovarian function, glucose and lipid metabolism, and inflammatory response, so as to provide theoretical basis for clinical intervention and prevention of BPA in the development of PCOS.

Objective:To study the correlation between osteoporosis and the joint of small articular process of lumbar vertebra,and the correlation between bone mineral density(BMD)and various parameters of small joint based on quantitative computed tomography(QCT),so as to provide scientific basis for formulating clinically treatment strategies.Methods:This study included 63 patients who admitted to orthopedics of The Second Affiliated Hospital of Liaoning University of Traditional Chinese Medicine from December 2023 to March 2024 due to waist discomfort and lower limb pain.According to BMD standard of CT examination for lumbar vertebra,these patients were divided into normal BMD group(31 cases),osteopenia group(21 cases)and osteoporosis group(11 cases).All patients underwent CT scan on lumbar vertebra.The mode with body membrane were adopted to measure BMD,the area of left and right articular process,CT value,height after the scan was completed.Whether existed osteophytes,endplate inflammation and intervertebral disc herniation in each group were checked.Univariate Analysis of Variance(ANOVA)was employed to assess the differences among different BMD groups in age,gender,area of articular process,CT value and height.The Pathria grading system was adopted to assess the degeneration degree of intervertebral joint,and the Fisher's exact test was used to analyze the differences in degeneration scores of articular process among three groups.At the same time,the pairwise comparison between groups also was conducted.Spearman's rank correlation analysis was conducted to explore the correlation between BMD and the degeneration degree of intervertebral joint.Results:The BMD value of normal BMD group was(165.14±30.11)mg/cm3,and that of osteopenia group was(98.98±10.14)mg/cm3,and that of osteoporosis group was(58.62±18.73)mg/cm3.There was a statistically significant difference in BMD value among three groups(F=103.121,P＜0.001),and there was a statistically significant difference in BMD value between normal BMD group and osteopenia group as the result of pairwise comparison between groups(t=10.018,P＜0.001).There was statistically significant difference in BMD value between normal BMD group and osteoporosis group(t=12.989,P＜0.001),and there was statistically significant difference in BMD value between osteopenia group and osteoporosis group(t=4.641,P＜0.001).The areas of left and right upper articular process of normal BMD group were less than that of other two groups,and the differences of CT value and height of left and right upper articular process among three groups were significant(F=27.350,24.458,P＜0.05),respectively.The CT value of normal BMD group was higher than that of other two groups,and CT values of right upper articular process of osteopenia group was significantly lower than that of osteoporosis group,and the difference was statistical significance(t=2.191,P＜0.05).The heights of left and right upper articular processes of normal BMD group were lower than those of osteoporosis group,and the height of right upper articular process was lower than that of osteopenia group(t=2.331,-2.798,-2.618,P＜0.05).There was a negative correlation between osteoporosis degree and the degeneration of articular process joints(r=-0.745,P＜0.001).With the decreasing of BMD value,the degeneration of articular process joint gradually aggravated,and the ratios of osteophytes,endplate inflammation and intervertebral discs increased.Conclusion:There is a certain correlation between the osteoporosis and the degeneration of articular process joints of lumbar intervertebral disc.The ratios of osteophytes,endplate inflammation and intervertebral disc herniation increase,and both the area and height of the left and right articular process increase when the reduction of bone mass reaches to a serious degree.
