		                        			ObjectiveTo investigate the effect and mechanism of Yishen Tongluo prescription in protecting mice from oxidative stress injury in diabetic kidney disease (DKD) via the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/NAD(P)H quinone oxidoreductase 1 (NQO1) signaling pathway. MethodsSpecific pathogen-free (SPF) male C57BL/6 mice were assigned into a control group (n=10) and a modeling group (n=50). The DKD model was established by intraperitoneal injection of streptozotocin. The mice in the modeling group were randomized into a model group, a semaglutide (40 μg·kg-1) group, and high-, medium-, and low-dose (18.2, 9.1, 4.55 g·kg-1, respectively) Yishen Tongluo prescription groups, with 10 mice in each group. The treatment lasted for 12 weeks. Blood glucose and 24-h urine protein levels were measured, and the kidney index (KI) was calculated. Serum levels of creatinine (SCr), blood urea nitrogen (BUN), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were assessed. The pathological changes in the renal tissue were evaluated by hematoxylin-eosin, periodic acid-Schiff, periodic acid-silver methenamine, and Masson’s trichrome staining. Enzyme-linked immunosorbent assay kits were used to measure the levels of β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), liver fatty acid-binding protein (L-FABP), nitric oxide synthase (NOS), glutathione (GSH), total antioxidant capacity (T-AOC), and 8-hydroxy-2'-deoxyguanosine (8-OHdG). Immunohistochemical staining was performed to examine the expression of Kelch-like ECH-associated protein 1 (Keap1) and malondialdehyde (MDA). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of factors in the Nrf2/HO-1/NQO1 signaling pathway. ResultsCompared with the control group, the DKD model group showed rises in blood glucose, 24-h urine protein, KI, SCr, BUN, and ALT levels, along with glomerular hypertrophy, renal tubular dilation, thickened basement membrane, mesangial expansion, and collagen deposition. Additionally, the model group showed elevated levels of β2-MG, NGAL, KIM-1, L-FABP, NOS, and 8-OHdG, lowered levels of GSH and T-AOC, up-regulated expression of MDA and Keap1, and down-regulated expression of Nrf2, HO-1, NQO1, and glutamate-cysteine ligase catalytic subunit (GCLC) (P<0.05). Compared with the model group, the semaglutide group and the medium- and high-dose Yishen Tongluo prescription groups showed reductions in blood glucose, 24-h urine protein, KI, SCr, BUN, and ALT levels, along with alleviated pathological injuries in the renal tissue. In addition, the three groups showed lowered levels of β2-MG, NGAL, KIM-1, L-FABP, NOS, and 8-OHdG, elevated levels of GSH and T-AOC, down-regulated expression of MDA and Keap1, and up-regulated expression of Nrf2, HO-1, NQO1, and GCLC (P<0.05). ConclusionYishen Tongluo prescription exerts renoprotective effects in the mouse model of DKD by modulating the Nrf2/HO-1/NQO1 signaling pathway, mitigating oxidative stress, and reducing renal tubular injuries.

		                        			ObjectiveTo investigate the anti-Alzheimer's disease (AD) effect of Dipsacus asper(DA) in the Caenorhabditis elegans model, and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α (PPARα)/transcription factor EB (TFEB) pathway. MethodsFirst, transgenic AD C. elegans individuals were assigned into the blank control, model, positive control (WY14643, 20 µmol·L-1), and low-, medium-, and high-dose (100, 200, and 400 mg·L-1, respectively) DA groups. The amyloid β-42 (Aβ42) formation in the muscle cells, the paralysis time, and the deposition of amyloid β-protein (Aβ) in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ, LC3I, LAMP2, and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα, and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain (LBD). ResultsCompared with the model group, the positive control group and 200 and 400 mg·L-1 DA groups showed prolonged paralysis time (P<0.05), and all the treatment groups showed decreased Aβ deposition in the head (P<0.01). DA within the concentration range of 50-500 mg·L-1 did not affect the viability of BV2 cells. In addition, DA enhanced the autophagy flux (P<0.05), up-regulated the mRNA levels of beclin1, Atg5, LAMP2, and CLN2 (P<0.05, P<0.01), promoted the nuclear translocation of TFEB (P<0.05), increased LAMP2 expression and autophagy flux (P<0.05, P<0.01), and enhanced the transcriptional activities of PPARα and TFEB (P<0.01). The positive control group and 200 and 400 mg·L-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus (P<0.01). UPLC-MS detected nine known compounds of DA, from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

		                        			Sixty C57BL/6 male mice were randomly divided into control (10 mice) and intervention groups (50 mice) using random number table method. The diabetes nephropathy model was established by intraperitoneally injecting streptozotocin(50 mg/kg). After modeling, the intervention group was further divided into model, semaglutide (40 μg/kg), and high-, medium-, and low-dose Yishen Tongluo Formula groups (15.6, 7.8, and 3.9 g/kg, respectively) using random number table method. The high-, medium-, and low-dose Yishen Tongluo Formula groups were administered corresponding doses of medication by gavage, the semaglutide group received a subcutaneous injection of semaglutide injection, and the control group and model groups were administered distilled water by gavage for 12 consecutive weeks. Random blood glucose levels of mice in each group were monitored, and the 24-h urinary protein content was measured using biochemical method every 4 weeks; after treatment, the serum creatinine and urea nitrogen levels were measured using biochemical method. The weight of the kidneys was measured, and the renal index was calculated. Hematoxylin and eosin, periodic acid-Schiff, periodic Schiff-methenamine, and Masson staining were used to observe the pathological changes in renal tissue. An enzyme-linked immunosorbent assay was used to detect urinary β2-microglobulin (β2-MG), neutrophil gelatinase-associated lipocalin (NGAL), and kidney injury molecule-1 (KIM-1) levels. Western blotting and real-time fluorescence PCR were used to detect the relative protein and mRNA expression levels of nucleotide-binding domain leucine-rich repeat and pyrin domain-containing receptor 3 (NLRP3), Caspase-1, gasdermin D (GSDMD), interleukin-1β (IL-1β), and interleukin-18 (IL-18) in renal tissue.

		                        			Objective Idiopathic rolandic epilepsy syndrome (IRES) is the most common epilepsy syndrome in childhood, and its lesion site remains undetermined. This article aims to investigate the source of epileptiform discharges in IRES using magnetoencephalography (MEG).Methods A total of 70 patients with IRES were enrolled in this prospective MEG-based study, among whom there were 53 children with benign epilepsy of childhood with centrotemporal spikes (BECTS), 12 children with atypical benign partial epilepsy (ABPE), 3 children with Landau-Kleffner syndrome (LKS), and 2 children with epileptic encephalopathy with continuous spike-and-waves during slow-wave sleep (CSWS). Epileptiform discharges were collected independently from each patient 10 times, and an MEG source analysis was performed. Standardized low-resolution brain electromagnetic tomography was used to perform source localization of the distributed source model. The spike source density was quantified into amplitude, and source location was determined according to the Desikan-Killiany atlas. The association between the distribution of spike source in brain and clinical manifestations was analyzed.Results In IRES, there were significant differences in the source locations of epilepsy discharge between BECTS, ABPE, LKS, and CSWS. The current source density of CSWS was stronger in the frontal lobe, the temporal lobe, and the anterior cingulate gyrus, while that of ABPE was stronger in the frontal lobe, and that of BECTS and LKS were stronger in the temporal lobe. The more severe phenotype of epilepsy, such as generalized tonic-clonic seizure, was associated with a stronger current source density in the brain, which was consistent with electroencephalography manifestations.Conclusion This study identifies different sources of epileptiform discharges in IRES. The density distribution of these spike sources may help to explain the discharge, cognitive, and neuropsychological characteristics in different subtypes of IRES.

		                        			Objective  To explore the application of seasonal autoregressive integrated moving average (ARIMA) model in the prediction of brucellosis in Urumqi, and to use this model to predict the incidence trend of brucellosis in Urumqi.  Methods  The monthly incidence data of brucellosis in Urumqi from January 2010 to December 2021 were selected to construct the ARIMA prediction model. The prediction effect of the model was evaluated by mean standard deviation (RMSE) and mean absolute error (MAE). The monthly incidence of brucellosis in Urumqi in 2022 was predicted by the constructed model.  Results  The incidence of brucellosis in Urumqi had obvious seasonal distribution, and the cases were concentrated from May to July. ARIMA(1,1,1)(1,0,1)12 was the optimal prediction model, with RMSE=0.883 and MAE=5.24. The monthly incidence of brucellosis in Urumqi in 2022 was predicted to be 7, 4, 4, 6, 9, 9, 10, 7, 7, 5, 5, and 5 cases, respectively.  Conclusion  ARIMA model can well fit and predict the monthly incidence of brucellosis in Urumqi and provide a basis for the monitoring and prevention of brucellosis.

		                        			Endometriosis is a common chronic gynecological disease with endometrial cell implantation outside the uterus.Angiogenesis is a major pathophysiology in endometriosis.Our previous studies have demon-strated that the prodrug of epigallocatechin gallate(ProEGCG)exhibits superior anti-endometriotic and anti-angiogenic effects compared to epigallocatechin gallate(EGCG).However,their direct binding targets and underlying mechanisms for the differential effects remain unknown.In this study,we demonstrated that oral ProEGCG can be effective in preventing and treating endometriosis.Additionally,1D and 2D Proteome Integral Solubility Alteration assay-based chemical proteomics identified metadherin(MTDH)and PX domain containing serine/threonine kinase-like(PXK)as novel binding targets of EGCG and ProEGCG,respectively.Computational simulation and BioLayer interferometry were used to confirm their binding affinity.Our results showed that MTDH-EGCG inhibited protein kinase B(Akt)-mediated angiogenesis,while PXK-ProEGCG inhibited epidermal growth factor(EGF)-mediated angiogenesis via the EGF/hypoxia-inducible factor(HIF-1a)/vascular endothelial growth factor(VEGF)pathway.In vitro and in vivo knockdown assays and microvascular network imaging further confirmed the involvement of these signaling pathways.Moreover,our study demonstrated that ProEGCG has superior therapeutic effects than EGCG by targeting distinct signal transduction pathways and may act as a novel anti-angiogenic therapy for endometriosis.

		                        			Objective:To investigate the predictive ability of Glypican-3 (GPC3) positive hepatocellular carcinoma based on the hepatobiliary specific contrast agent gadoxetate disodium enhancement of the liver imaging reporting and data system version 2018 (LI-RADS v2018) imaging features, and to assess the relevant clinical imaging features for postoperative recurrence in GPC3 positive HCC patients.Methods:This study was a cohort study. A total of 122 hepatocellular carcinoma patients who underwent gadoxetate disodium enhanced MRI examination with hepatic tumor resection in Henan Provincial People′s Hospital from January 2017 to December 2021 were retrospectively collected, including 96 GPC3 positive and 26 GPC3 negative patients. The imaging features defined by LI-RADS v2018 of HCC lesions were analyzed. Patients were followed up for 40 months to determine recurrence free survival (RFS). The logistic regression was used to analyze the risk factors of GPC3 positivity. An imaging model, and a clinical-imaging model which combined the patient′s alpha-fetoprotein levels were constructed. The efficacy of the model for predicting GPC3 positivity was assessed using receiver operating characteristic curves. Kaplan-Meier method was used to draw the survival curve, and the log-rank test was used to compare the RFS between GPC3 positive and negative patients. Risk factors affecting the recurrence of GPC3 positive HCC were assessed by Cox regression.Results:The results of logistic multivariate regression analysis confirmed that rim enhancement ( OR=5.685, 95% CI 1.229-26.287, P=0.026) and irregular tumor margin at hepatobiliary phase ( OR=4.431, 95% CI 1.684-11.663, P=0.003) were independent risk factors for GPC3 positive HCC. The area under the curve for predicting GPC3 positivity was 0.745 (95% CI 0.636-0.854) for the imaging model and 0.776 (95% CI 0.677-0.876) for the clinical-imaging model. The mean RFS in the GPC3 positive group was 22 months, and it was 32 months in the negative group. There was a statistically significant difference in RFS between the two groups ( χ2=5.15, P=0.023). The multivariate Cox regression analysis showed that the arterial rim enhancement ( HR=5.460, 95% CI 1.966-15.162, P=0.001), microvascular invasion ( HR=2.402, 95% CI 1.210-4.769, P=0.012), portal vein tumor thrombus ( HR=3.226, 95% CI 1.114-9.344, P=0.031) were independent risk factors for recurrence after hepatic tumor resection for GPC3-positive HCC. Conclusions:A model based on the LI-RADS v2018 imaging features of hepatobiliary specific contrast agent gadoxetate disodium enhancement can effectively predict GPC3 positive HCC. The arterial rim enhancement, microvascular invasion and portal vein tumor thrombus are independent risk factors for postoperative recurrence of GPC3 positive HCC.

		                        			To investigate the protective effect of paeoniflorin(PF) on cardiac dysfunction and myocardial cell injury induced by cisplatin(CDDP) in rats.
METHODS 
SD male rats were randomly divided into control group, CPPD group, and CDDP PF+low-dose, high-dose group. PowerLab multifunctional recorder was used to detect the related indexes of cardiac function: the changes of left ventricular peak pressure(LVSP), left ventricular end-diastolic pressure(LVEDP) and left ventricular pressure change rate(±dp/dt). Serum levels of inflammatory factors TNF-α, IL-1β and IL-6 were measured in each group. Myocardial tissue was stained to observe the changes of tissue structure. H9c2 cardiomyocytes were divided into control group, CDDP group, PF group and CDDP+PF group. The activity of H9c2 cardiomyocytes was measured by CCK-8. The apoptosis of cardiomyocytes in each group was detected by flow cytometry. The expressions of MAPK signaling pathway related proteins p38, ERK, JNK and their phosphorylated proteins and apoptosis-related proteins Bax, Bcl-2, Casp3, Cl-casp3 were detected in cardiomyocytes by Western blotting.
RESULTS 
Compared with the control group, LVSP and ±dp/dt decreased, LVEDP increased in rats of CDDP group(P<0.01). Compared with CDDP group, both CDDP+low-dose and high-dose PF pretreatment increased LVSP and ±dp/dt value(P<0.05 or P<0.01), decreased LVEDP(P<0.01), and could decrease the serum inflammatory factor TNF-α, IL-1β and IL-6(P<0.01). Cell level results showed that compared with control group, in CDDP group, the cell activity decreased, the apoptosis-related protein Bax, Cl-casp3 increased(P<0.01), expression of anti-apoptotic protein Bcl-2 decreased(P<0.01), and the expression of p38 and ERK phosphorylation also increased(P<0.01). Compared with CDDP group, PF could restore cell activit, down-regulate apoptosis-related protein Bax, Cl-casp3(P<0.05 or P<0.01), and increase anti-apoptotic protein Bcl-2 expression(P<0.01), inhibit MAPK pathway p38 and ERK phosphorylation expression(P<0.01).
CONCLUSION 
PF can restore cardiac dysfunction and myocardial cell injury induced by cisplatin in rats, which may be related to inhibiting inflammation and apoptosis by regulating ERK/p38 MAPK signal expression.

		                        			Objective:To quantitatively evaluate the guidelines for hypertensive disorders of pregnancy (HDP) at home and abroad, and to provide a reference for the development of related guidelines in the future.Methods:Guidelines related to HDP published at home and abroad from 1 January 2018 to 31 December 2022 were retrieved from several databases, including CNKI, Wanfang Database, Yiigle, VIP Database, PubMed, Embase, and Web of Science with the terms of "hypertension in pregnancy", "hypertensive disorders of pregnancy", "pre-eclampsia", "eclampsia", and "guidelines". The retrieved guidelines were evaluated with the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ) and Scientific, Transparent and Applicable Rankings (STAR) tool. According to the manual of AGREE Ⅱ two researchers graded the retrieved guidelines from six domains: scope and purpose, participants, rigor, clarity, applicability, and independence. Mean standardized score of each domain and the overall score were obtained. STAR tool was used to grade the guidelines by two researchers and one methodologist from 11 domains: registration, protocol, funding, working groups, conflicts of interest, clinical issues, evidence, consensus methods, recommendations, accessibility, and others.Results:A total of 19 related guidelines were included, covering six countries on three continents. The mean standardized scores of the 19 guidelines in the six domains of scope and purpose, participants, rigor, clarity, applicability, and independence using the AGREE II instrument were 73.98%, 63.16%, 59.98%, 66.37%, 56.36%, and 71.93%, respectively. Scores in the 11 domains of registration, protocol, funding, working groups, conflicts of interest, clinical issues, evidence, consensus methods, recommendations, accessibility, and others using the STAR tool were 0.00%, 0.00%, 76.15%, 39.87%, 58.92%, 65.19%, 60.80%, 49.78%, 78.95%, 30.89%, and 42.11%, respectively. According to the overall evaluation results, 12 guidelines were recommended and seven needed further modifications. It was found that most guidelines were unanimous in their recommendations on the prevention of preeclampsia with aspirin, medications for patients with severe hypertension, and the timing of pregnancy termination in preeclampsia patients, with the consensus rates of 10/13, 9/13, and 9/13, respectively. Besides, these recommendations were supported by substantial evidence.Conclusions:The overall quality of guidelines related to HDP at home and abroad is high, but there is still room for improvement. When developing relevant guidelines in the future, statisticians and methodologists should be included in the working groups to improve the evidence-based quality, and much attention should be paid to the disclosure of conflicts of interest guidelines. Registration and protocol are needed before publishing a guideline. The development of multiple versions for different users will conduce to improving the management of HDP.
