ObjectiveTo explore the mechanism of the Wenyang Jieyu prescription in regulating depression-like behavior in mice after maternal-infant separation combined with secondary stress. MethodsAfter birth, the rats were randomly divided into blank (NC) group, maternal-infant separation (MS) group, restraint stress (RS) group, maternal-infant separation combined with restraint stress (MRS) group, Wenyang group, Jieyu group, Wenyang Jieyu (XSF) group, and minocycline group. Maternal-infant separation was performed on day 5 (PD5), followed by weaning at PD21 and prophylactic administration. The dose of Wenyang group, Xiaoyao group, XSF group and minocycline group were 5.85, 12.03, 16.71 g·kg-1 and 50 mg·kg-1, respectively. Restraint stress was applied on PD90. The model was evaluated using glucose, social interaction, open field, and O-maze behavior tests, as well as high-performance liquid chromatography to measure serotonin, dopamine, and other neurotransmitters. The expression level of ionized calcium-binding adaptor molecule-1 (Iba-1) protein, a marker of hippocampal microglia, was detected by immunohistochemistry. Protein expression levels of Janus kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) in the hippocampus were analyzed by an automatic protein expression analysis system. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to detect mRNA expression levels of M1 markers, JAK2/STAT3 pathway-related genes, and cytokines in hippocampal microglia in each group. ResultsCompared with the NC group, the MRS group exhibited depression-like behavior, with significantly decreased levels of neurotransmitters in the hippocampus (P<0.05, P<0.01), increased expression of Iba-1 (P<0.01), and elevated protein levels of JAK2 and STAT3 (P<0.05). The mRNA expression levels of CD68, CD11b, IL-1β, JAK2, and STAT3 were significantly increased (P<0.01), while IL-10 mRNA expression was significantly decreased (P<0.01). Compared with the MRS group, the XSF and minocycline groups showed some improvement in depression-like behavior. In these groups, the hippocampal neurotransmitter content was significantly increased (P<0.05, P<0.01), and Iba-1 expression was significantly decreased (P<0.01). The protein levels of JAK2 and STAT3 in the XSF group showed a downward trend. The mRNA expression levels of CD68, CD11b, JAK2, STAT3, and IL-1β in the hippocampus were significantly decreased in the XSF and minocycline groups (P<0.05, P<0.01), while IL-10 mRNA expression was significantly increased (P<0.05, P<0.01). ConclusionWenyang Jieyu prescription can regulate depression-like behavior in maternal-infant separation mice combined with secondary stress by inhibiting the polarization of hippocampal microglia to the M1 phenotype. The regulation of hippocampal microglia polarization by Wenyang Jieyu prescription may be associated with the JAK2/STAT3 pathway.

ObjectiveTo explore the syndromes and mechanisms of depression induced by maternal separation (MS) combined with chronic restraint stress (RS) in mice. MethodOn postnatal day 0 (PD0), the offspring mice were randomized into a blank group (NC) and a modeling group. The mouse model of depression was established by MS+RS for 21 days. After removal of female mice on PD21, the modeled mice were randomized into model, Wenyang, Jieyu, Wenyang Jieyu, and fluoxetine groups, with 15 mice in each group. The sucrose preference, tail suspension, and open field tests were carried out to evaluate the anxiety and depression-like behavior in mice. Enzyme-linked immunosorbent assay was used to measure the adrenocorticotrophic hormone (ACTH) and corticosterone (CORT) levels in mouse plasma. High performance liquid chromatography-electrochemical detector was used to determine the content of monoamine neurotransmitters in the hippocampus. Real-time fluorescence quantitative polymerase chain reaction was employed to determine the mRNA levels of genes in the 5-hydroxytryptamine (5-HT) system, hypothalamic-pituitary-adrenal (HPA) axis, and brain-derived neurotrophic factor (BDNF) signaling pathway in the hippocampus. Immunohistochemistry was employed to determine the expression levels of proteins in the 5-HT system and HPA axis in the hippocampus. The Simple Western system was used to determine the protein levels of BDNF and tyrosine kinase receptor B (TrkB) in the hippocampus. ResultCompared with the NC group, the model group exhibited depression-like behavior, which was significantly relieved by Wenyang Jieyu prescription and fluoxetine. Compared with the NC group, the model group showed elevated levels of CORT and ACTH in the plasma (P<0.01), which, however, were lowered by Wenyang Jieyu prescription and fluoxetine (P<0.05, P<0.01). Compared with the NC group, the model group showed inhibited expression of neurotransmitters in the hippocampus (P<0.05, P<0.01), while Wenyang Jieyu prescription and fluoxetine restored the expression of neurotransmitters (P<0.05, P<0.01). Compared with NC group, the model group showed inhibition of the 5-HTergic nerve and abnormal activation of the HPA axis, and Wenyang Jieyu prescription and fluoxetine regulated the abnormal state of the 5-HTergic nerve and HPA axis. Compared with NC group, the modeling down-regulated the mRNA and protein levels of BDNF and TrkB in the hippocampus (P<0.05, P<0.01), which, however, were recovered in Wenyang, Jieyu, Wenyang Jieyu, and fluoxetine groups (P<0.05, P<0.01). ConclusionThe mouse model of depression induced by MS+RS may present the syndrome of Yang deficiency and liver depression. Wenyang Jieyu prescription may increase the content of hippocampal neurotransmitters by regulating the 5-HT system and the BDNF signaling pathway mediated by the HPA axis, thereby alleviating depression-like behavior in mice.

Objective:To analyze the expression level of hepcidin in urine of patients with type 2 diabetic kidney disease (DKD) in different stages and its relationship with DKD and related indicators.Methods:From June 2022 to December 2023, 139 inpatients with type 2 diabetes mellitus in the Department of Endocrinology, Zhoupu Hospital Affiliated to Shanghai Health Medical College were selected as the research objects. The stage of DKD was judged by urinary albumin/creatinine ratio (UACR): UACR <30 mg/g in stage A1, UACR ≥30 mg/g~≤300 mg/g in stage A2. DKD in stage A3 was UACR >300 mg/g. According to the stage of DKD, there were 50 patients with stage A1 (group A1), 47 patients with stage A2 (group A2), and 42 patients with stage A3 (group A3). Urinary hepcidin was determined by enzyme-linked immunosorbent assay, and fasting blood glucose, total cholesterol, triglyceride, alanine aminotransferase (ALT), serum creatinine and hemoglobin A1c (HbA1c) were measured and compared. The correlation between urinary hepcidin and other markers, the risk factors of DKD and the evaluation of diagnostic value were analyzed. Measurement data with normal distribution were expressed as xˉ± s, mean comparison among the three groups, if the variance was homogeneous, the analysis of variance test was used; if the variance was not homogeneous, the Welch test was used; the proportion or rate of enumeration data among the groups was tested by χ2 test; Pearson correlation analysis was used for correlation analysis; binary Logistic regression model was used for multivariate analysis; The value of urinary hepcidin in the diagnosis of DKD was analyzed by receiver operating characteristic curve. Results:Urinary hepcidin was (5.3±1.0) μg/L in group A1, (7.7±2.5) μg/L in group A2, and (10.1±2.7) μg/L in group A3. There was significant difference among the three groups ( F=58.92, P<0.001), and urinary hepcidin increased with the severity of DKD; Urinary Hepcidin was related to UACR ( R=0.684, P<0.001), serum creatinine ( R=0.590, P<0.001), course of disease ( R=0.485, P<0.001), triglyceride ( R=0.264, P=0.002), age ( R=0.235, P<0.001), P=0.005), total cholesterol ( R=0.224, P=0.008), systolic pressure ( R=0.194, P=0.022), glomerular filtration rate ( R=-0.540, P<0.001) and BMI ( R=-0.175, P=0.040); There was no correlation with fasting blood glucose, HbA1c, ALT and diastolic blood pressure (all P>0.05). Secondly, the increase of urinary hepcidin level was a risk factor for DKD by binary Logistic regression analysis ( OR=4.147,95% CI: 2.154-7.984, P<0.001). Finally, receiver operating characteristic curve analysis showed that the optimal cut-off point of urinary hepcidin was 6.35 μg/L, with a sensitivity of 0.831 and a specificity of 0.880. Conclusion:Urinary hepcidin increases with the severity of DKD, which may be a biomarker for early diagnosis of DKD.

Objective:To explore the consistency between modified 12+ X prostate biopsy under transrectal interventional ultrasound and postoperative Gleason score in prostate cancer patients.Methods:A retrospective study was conducted on 312 patients diagnosed with prostate cancer and underwent radical resection at Zhongshan People′s Hospital from January 2020 to December 2022. All patients underwent modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound before surgery. Using the Gleason score of postoperative pathological specimens as the " gold standard", the detection rates of prostate cancer and clinically significant prostate cancer using modified 12+ X prostate biopsy and prostate system biopsy under transrectal interventional ultrasound were compared, and the consistency between the two methods alone or in combination and postoperative Gleason score was compared.Results:Among 312 patients, the positive detection rate of the improved 12+ X puncture biopsy combined with the system puncture biopsy was significantly higher than that of the individual detection (95.51% vs 80.77% vs 76.92%), with a statistically significant difference ( P<0.05). The improved 12+ X puncture biopsy combined with system puncture biopsy showed a clinically significant higher detection rate of prostate cancer in positive patients compared to the two tests alone (94.63% vs 77.78% vs 80.00%), with a statistically significant difference ( P<0.05). There was no statistically significant difference in the detection rate of clinically significant prostate cancer among patients who missed diagnosis, either alone or in combination with biopsy ( P>0.05). The upgrade rate of Gleason score after prostate improvement 12+ X puncture biopsy (25.00%) was significantly lower than that of prostate system puncture (44.17%), which was significantly higher than combined puncture biopsy (11.74%), with a statistically significant difference ( P<0.05). After 312 patients received combined puncture biopsy, urinary retention was found in 14 cases (4.49%), hematuria in 30 cases (9.62%), fever in 28 cases (8.97%), and blood in stool in 18 cases (5.77%). After symptomatic treatment, they basically improved within 3 days after puncture. Conclusions:The combination of modified 12+ X prostate biopsy with systematic biopsy under transrectal interventional ultrasound can improve the detection rate of prostate cancer, and has good consistency with the postoperative Gleason score of prostate cancer patients, which has good clinical application value.

ObjectiveTo explore the mechanism of Xiaoyaosan in alleviating lipopolysaccharide (LPS)-induced depressive-like behavior in mice based on the c-Jun N-terminal kinase (JNK) pathway. MethodAfter adaptive feeding, C57BL/6J mice were randomly divided into normal group, model group, minocycline group (intrabitoneal injection, 50 mg·kg-1), fluoxetine group (intragastric administration, 2.6 mg·kg-1), and low-, medium-, and high-dose Xiaoyaosan groups (intragastric administration,6.012 5, 12.025, and 24.050 g·kg-1). After 14 days of administration, the model group and each administration group were intraperitoneally injected with 2 mg·kg-1 LPS, and the normal group was intraperitoneally injected with equal volume of normal saline. Depressive-like behavior in mice was assessed using the open field test and the elevated zero maze test. High-performance liquid chromatography (HPLC) was used to measure the levels of norepinephrine (NE) and epinephrine (E) in the mouse hippocampus. Enzyme-linked immunosorbent assay (ELISA) was performed to determine serum interleukin-1β (IL-1β) levels. Immunohistochemistry was used to measure the protein expression levels of ionized calcium-binding adapter molecule-1 (Iba-1), c-Fos, and c-Jun. Real-time polymerase chain reaction (Real-time PCR) was used to measure mRNA expression levels of IL-1β, c-Jun, c-Fos, and JNK3 in the mouse hippocampus. Protein expression levels of JNK and phosphorylated (p)-JNK in the mouse hippocampus were measured using capillary protein automated protein expression analysis system (Western). ResultCompared with the normal group, the model group exhibited significantly reduced central area residence time, crossing times, and travel distance in the open field (P<0.01), significantly increased serum IL-1β levels (P<0.01), significantly decreased NE and E levels (P<0.05), upregulated mRNA expression of IL-1β, JNK3, and c-Fos, and increased protein expression of Iba-1, c-Fos, and c-Jun (P<0.05, P<0.01). Compared with the model group, the Xiaoyaosan groups showed increased central area residence time and open arm residence time (P<0.05), increased NE and E levels (P<0.01), decreased mRNA expression of IL-1β, JNK3, c-Jun, and c-Fos, and decreased protein expression of Iba-1, c-Fos, JNK, and p-JNK (P<0.05, P<0.01). The minocycline group and the fluoxetine group showed decreased mRNA expression of JNK3, c-Jun, and c-Fos (P<0.05, P<0.01). The minocycline group showed decreased serum IL-1β and p-JNK protein expression (P<0.01). The fluoxetine group exhibited increased NE and E levels and decreased c-Fos protein expression (P<0.01). ConclusionXiaoyaosan can improve depressive-like behavior induced by LPS in mice, and its mechanism may be related to the inhibition of neuroinflammatory responses and the JNK pathway.

Objective:To investigate the effect of on-demand glucocorticoid strategy on the occurrence and outcome of porcine anti-lymphocyte globulin (p-ALG) -associated serum sickness in aplastic anemia (AA) .Methods:The data of AA patients who received in the Anemia Diagnosis and Treatment Center of Haematology Hospital, CAMS & PUMC from January 2019 to January 2022 were collected. Among them, 35 patients were enrolled in the on-demand group, with the glucocorticoid strategy adjusted based on the occurrence and severity of serum sickness; 105 patients were recruited in the usual group by matching the age and disease diagnosis according to 1∶3 ratio in patients who received a conventional glucocorticoid strategy in the same period. The incidences, clinical manifestations, treatment outcomes of serum sickness, and glucocorticoid dosage between the two groups were analyzed.Results:The incidences of serum sickness in the on-demand group and the usual group were 65.7% and 54.3% ( P=0.237) , respectively. The median onset of serum sickness was the same [12 (9, 13) d vs the 12 (10, 13) d, P=0.552], and clinical symptoms and signs, primarily joint, and/or muscle pain, fever, and rash were similar. Severity grades were both dominated by Grades 1-2 (62.8% vs 51.4%) , with only a few Grade 3 (2.9% vs 2.9%) , and no Grades 4-5. No significant difference in the serum sickness distribution ( P=0.530) . The median duration of serum sickness was the same [5 (3, 7) d vs 5 (3, 6) d, P=0.529], and all patients were completely cured after glucocorticoid therapy. In patients without serum sickness, the average dosage of prophylactic glucocorticoid per patient in the usual group was (469.48 ±193.57) mg (0 in the on-demand group) . When compared to the usual group, the average therapeutic glucocorticoid dosage per patient in the on-demand group was significantly lower [ (125.91±77.70) mg vs (653.90±285.56) mg, P<0.001]. Conclusions:In comparison to the usual glucocorticoid strategy, the on-demand treatment strategy could significantly reduce glucocorticoid dosage without increasing the incidence of serum sickness; in addition, the duration of serum sickness and the incidence of above Grade 2-serum sickness were similar.

ObjectiveTo predict the potential molecular mechanism of Erxian decoction in the treatment of anxiety disorder based on network pharmacology, and to verify the efficacy and mechanism using the animal model of maternal separation combined with restraint stress. MethodActive components and related targets of Erxian decoction were obtained by traditional Chinese medicine system pharmacology database and analysis platform (TCMSP) and SwissTargetPrediction. The targets related to anxiety disorder were screened out through GeneCards, therapeutic target database (TTD), online mendelian inheritance in man database (OMIM), and DrugBank, and the drug-disease intersection targets were obtained by taking intersections with the drug targets. The protein-protein interaction (PPI) network was constructed by the STRING database, and the core targets were screened out based on topological parameter analysis. Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were carried out for the intersection targets through the Metascape platform. Maternal separation combined with restraint stress was used to induce the mouse model of anxiety disorder. From the end of lactation on the 21st postnatal day (PD21) to the completion of restraint stress on the 97th postnatal day (PD97), the mice were fed with Erxian decoction mixed with diet. The anxiety state of mice was evaluated by open field test and elevated O-maze test. The content of plasma corticosterone (CORT) in mice was detected by enzyme-linked immunosorbent assay (ELISA). The expression levels of protein kinase B (Akt1), mammalian target of rapamycin (mTOR), brain-derived neurotrophic factor (BDNF), postsynaptic density-95 (PSD95), and synaptophysin in the hippocampus of mice were detected by Western blot and real-time quantitative polymerase chain reaction (Real-time PCR). ResultNinty-seven active components and 227 action targets of Erxian decoction were obtained. There were 3 863 targets related to anxiety disorder, with 161 drug-disease intersection targets. Among these intersection targets, core targets such as Akt1, interleukin-1β (IL-1β), interleukin-6 (IL-6), tumor necrosis factor (TNF), and mTOR were presumedly closely related to anxiety disorder. The results of KEGG pathway analysis showed that Erxian decoction mainly treated anxiety disorder through phosphatidylinositol 3-kinase (PI3K)/Akt, mitogen-activated protein kinase (MAPK), and neuroactive ligand-receptor interaction signaling pathways. The results of animal experiments showed that compared with the model group, the Erxian decoction group significantly increased the time of mice spent in the central zone and central crossing times and time spent in the opened arm and opened arm crossing times, with significantly increased expression levels of p-Akt1, p-mTOR, BDNF, PSD95, and synaptophysin (Syp). ConclusionErxian decoction has the multi-target and multi-pathway characteristics in the treatment of anxiety disorder, and its mechanism may be related to the improvement of synaptic plasticity and neuroinflammation by affecting Akt1, IL-1β, IL-6, TNF, mTOR, and other core targets and modulating PI3K/Akt, MAPK, as well as neuroactive ligand-receptor interaction signal pathways.

ObjectiveTo predict the molecular mechanism of Erxian decoction and Wenshen prescription (modified Erxian decoction) in the treatment of depression based on network pharmacology and explore the feasibility of Wenshen prescription in the treatment of depression by comparing the efficacy and mechanism of the two decoctions based on a depression model induced by maternal separation combined with chronic restraint stress. MethodActive components and targets of Erxian decoction and Wenshen prescription were collected through Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and Bioinformatics Analysis Tool for Molecular mechanism of Traditional Chinese Medicine (BATMAN-TCM). Targets related to depression were screened out from databases such as GeneCards, Online Mendelian Inheritance in Man database (OMIM), and DrugBank. Common targets of drugs and disease were obtained and imported to Cytoscape 3.8.2 to plot the drug-active component-target-disease network. STRING platform was used to construct a protein-protein interaction (PPI) network and core targets and related core components were screened out. Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional enrichment analysis were performed on common targets through Metascape platform. The depression model was induced in mice by maternal separation combined with chronic restraint stress. From the 21st day of maternal separation (PD21) to the 111th day of restraint stress completion (PD111), mice were fed with the diet mixed with Erxian decoction or Wenshen prescription for intervention. The depressive state of mice was evaluated according to the sucrose preference test, tail suspension test, open field test, and elevated O-maze test. The expression of ionized calcium-binding adapter molecule 1 (Iba1) in the microglia was observed by immunohistochemistry (IHC). Western blot and Real-time fluorescence-based quantitative polymerase chain reaction (Real-time PCR) were used to detect the expression levels of protein kinase B1(Akt1), brain-derived neurotrophic factor (BDNF), postsynaptic density-95 (PSD95), and synaptophysin (Syn). ResultA total of 126 and 118 targets of Erxian decoction and Wenshen prescription in the treatment of depression were screened out, with only eight more targets of Erxian decoction than Wenshen prescription. The two decoctions shared the same core targets, mainly including Akt1, interleukin-6 (IL-6), interleukin-1β (IL-1β), and tumor necrosis factor-α (TNF-α). KEGG pathway enrichment analysis predicted that Erxian decoction and Wenshen prescription mainly treated depression through the phosphatidylinositol-3 kinase (PI3K)/Akt signaling pathway, mitogen-activated protein kinase (MAPK) signaling pathway, and neuroactive ligand-receptor interaction pathway. Animal experiments showed that compared with the results in the model group, Erxian decoction and Wenshen prescription could up-regulate the sucrose preference index, prolong the time spent in the central zone, increase the number of crossings, prolong the time spent in opened arm, increase the number of crossings in the opened arm, elevate the expression levels of p-Akt1, BDNF, PSD95, and Syn (P<0.05, P<0.01), shorten the immobility time of tail suspension, and reduce the expression level of Iba-1 in the hippocampal microglia (P<0.05, P<0.01). No significant difference between the two decoctions was found. ConclusionUnder the pathogenesis and syndrome law of depression dominated by kidney yang deficiency, Wenshen prescription modified from Erxian decoction is feasible in the treatment of depression. The mechanism may be attributed to the fact that both decoctions can improve neuroinflammation and synaptic plasticity in the hippocampus by affecting Akt1, IL-1β, IL-6, TNF-α, and other core targets and regulating the PI3K/Akt, MAPK, and neuroactive ligand-receptor interaction signaling pathways.
