ObjectiveHepatocyte nuclear factor 4-alpha (HNF4A) is a critical transcription factor in the liver and pancreas. Dysfunctions of HNF4A lead to maturity onset diabetes of the young 1 (MODY1). Notably, MODY1 patients with HNF4A pathogenic mutations exhibit decreased responses to arginine and reduced plasma triglyceride levels, but the mechanisms remain unclear. This study aims to investigate the potential target genes transcriptionally regulated by HNF4A and explore its role in these metabolic pathways. MethodsA stable 293T cell line expressing the HNF1A reporter was overexpressed with HNF4A. RNA sequencing (RNA-seq) was performed to analyze transcriptional differences. Transcription factor binding site prediction was then conducted to identify HNF4A binding motifs in the promoter regions of relevant target genes. ResultsRNA-seq results revealed a significant upregulation of transmembrane 4 L six family member 5 (TM4SF5) mRNA in HNF4A-overexpressing cells. Transcription factor binding predictions suggested the presence of five potential HNF4A binding motifs in the TM4SF5 promoter. Finally, we confirmed that the DR1 site in the -57 to -48 region of the TM4SF5 promoter is the key binding motif for HNF4A. ConclusionThis study identified TM4SF5 as a target gene of HNF4A and determined the key binding motif involved in its regulation. Given the role of TM4SF5 as an arginine sensor in mTOR signaling activation and triglyceride secretion, which closely aligns with phenotypes observed in MODY1 patients, our findings provide novel insights into the possible mechanisms by which HNF4A regulates triglyceride secretion in the liver and arginine-stimulated insulin secretion in the pancreas.

ObjectiveTo observe the therapeutic effect of Shugan Huazheng prescription on hepatic fibrosis model rats induced by carbon tetrachloride （CCl₄） and explore whether it plays its role through hypoxia-induced factor-1α/vascular endothelial growth factor/transforming growth factor-β₁ （HIF-1α/VEGF/TGF-β₁） pathway. MethodA total of 54 male SPF SD rats were randomly divided into six groups： blank group， model group， colchicine group （0.2 mg·kg^-1）， and high-， medium-， and low-dose groups （29.52， 14.76， and 7.38 g·kg^-1） of Shugan Huazheng prescription， with nine rats in each group. The molding was conducted three times a week for eight weeks. Administration began the day after the first injection， and the drug intervention was once a day for eight weeks. On the day after the last administration， the rats were deprived of food and water， and they were killed the next day， during which the physiological status of each group of rats was dynamically monitored. The pathological changes in the liver were observed by hematoxylin-eosin （HE） staining， and the content of hydroxyproline （HYP） and angiotensin Ⅱ （AngⅡ） in liver tissue were detected by enzyme-related immunosorbent assay （ELISA）. Real-time fluorescent quantitative PCR （Real-time PCR） was used to determine the mRNA expression levels of HIF-1α， VEGF， and TGF-β₁ in liver tissue， and immunohistochemical method （IHC） and Western blot were used to detect the protein expression levels of HIF-1α， VEGF， and TGF-β₁ in liver tissue. ResultCompared with the blank group， the overall condition of rats in the model group decreased significantly. The proliferation of connective tissue and the increase in adipose cells between hepatocytes were obvious. The content of HYP and Ang was increased. The mRNA and protein expressions of HIF-1α， VEGF， and TGF-β₁ were increased to varying degrees （P<0.05）. Compared with the model group， the proliferation of connective tissue and inflammatory cell infiltration in the liver tissue of colchicine and Shugan Huazheng prescription groups were reduced. The content of HYP and Ang was decreased. The mRNA and protein expression levels of HIF-1α， VEGF， and TGF-β₁ were decreased， and the colchicine group and high-dose group of Shugan Huazheng prescription were the most significant （P<0.05）. ConclusionShugan Huazheng prescription has an obvious therapeutic effect on CCl₄-induced hepatic fibrosis model rats. Its therapeutic mechanism may be related to the regulation of the HIF-1α/VEGF/TGF-β₁ signaling pathway and the improvement of hepatic hypoxia， vascular remodeling， and the syndrome of Qi deficiency and blood stasis in hepatic fibrosis.

ObjectiveTo decipher the mechanism of Wenxiao powder in alleviating corticosterone-induced depression-like behaviors in mice. MethodMale ICR mice were randomized into normal， model， paroxetine （20 mg·kg^-1）， and low- and high-dose （3.27， 6.54 g·kg^-1， respectively） Wenxiao powder groups. The mice in normal and model groups received equal volume of saline. Other groups except the normal group were injected with corticosterone subcutaneously 0.5 h after gavage to induce depression. Mice were tested for depression-like behaviors after drug administration. Enzyme-linked immunosorbent assay （ELISA） was performed to measure the corticosterone content in the serum. Nissl staining was performed to observe the damage of hippocampal neurons. Immunofluorescence staining was employed to observe the expression of double cortin （DCX） in the dentate gyrus （DG） of the hippocampus. Western blot was employed to determine the expression of proteins in the brain-derived neurotrophic factor （BDNF）/tyrosine kinase receptor B （TrkB）/extracellular signal-regulated kinase （ERK）/cAMP-response element-binding protein （CREB） pathway in the hippocampus. ResultCompared with the normal group， the model group showed decreased sucrose preference rate， increased immobility time in the tail suspension test （P<0.01）， and reduced residence time in the central area of the open field and the total movement distance （P<0.05， P<0.01）. In addition， the modeling elevated the corticosterone level in the serum （P<0.01）， decreased the volume and intensified the nuclear staining of hippocampal neurons in the DG area， reduced the expression of DCX in the DG area， and down-regulated the protein levels of BDNF， phosphorylated （p）-TrkB， p-ERK， and p-CREB in the hippocampus （P<0.05， P<0.01）. Compared with the model group， low-dose Wenxiao powder improved the mouse behavivors in the sucrose preference， open field， and tail suspension tests （P<0.05， P<0.01）， and high-dose Wenxiao powder improved the behaviors in the sucrose preference and open field tests （P<0.05， P<0.01）. In addition， Wenxiao powder lowered the serum corticosterone level （P<0.01） and recovered the structure and morphology of neurons with obvious nuclei and presence of Nissl bodies in the DG area of the hippocampus. Moreover， Wenxiao powder at both doses promoted the expression of DCX in the DG area， and high-dose Wenxiao powder up-regulated the protein levels of BDNF， p-TrkB， p-ERK， and p-CREB in the hippocampus （P<0.05， P<0.01）. ConclusionWenxiao powder can alleviate corticosterone-induced depression-like behaviors and promote neurogenesis in mice possibly by activating the BDNF/TrkB/ERK/CREB signaling pathway.

Objective:To compare the difference between the operation of ureteral calculi patients with COVID-19 infection during COVID-19 infection and after recovery to find out the best timing for surgery.Methods:The clinical data of 327 ureteral calculi patients with COVID-19 infection were retrospectively analyzed, including 141 cases who underwent ureteroscopic surgery. According to the time of ureteroscopic surgery, the patients were divided into two groups: operation before recovery of COVID-19 infection group ( n=81) and operation after recovery of COVID-19 infection group ( n=60). The success rate of primary surgery, stone removal incidence, complication inciednce, mortality, operation time, postoperative hemoglobin decline, hospital stay, and total hospitalization cost and other indicators of the two groups were compared between the two groups. Measurement data were expressed as mean±standard deviation ( ± s), independent t-test was used for inter-group comparison. Chi-test or continuous correction Chi-test was used for inter-group comparison for count data. Results:The success rate of primary surgery (38.3%, 31/81), stone removal rate (86.4%, 70/81) in the operation before recovery of COVID-19 infection group were significantly lower than those in the operation after recovery of COVID-19 infection group [80.0% (48/60), 98.3% (59/60)], and the differences were statistically significant ( P< 0.05). The incidence of complication, postoperative hemoglobin decline [(2.1±0.6) g/L vs (0.6±0.3) g/L], hospital stay [(14.7±3.6) d vs (4.1±1.1) d], total hospitalization cost [(34 733.3±4 412.4) yuan vs (21 919.7±3 251.3) yuan] of the operation before recovery of COVID-19 infection group were significantly higher than those in the operation after recovery of COVID-19 infection group, and the differences were statistically significant ( P< 0.001). The operation time of the operation before recovery of COVID-19 infection group was shorter [(16.9±5.4) min vs (37.7±8.9) min], and the difference was statistically significant ( P< 0.001). There was no significant difference in mortality between the two groups (3.7% vs 0, P> 0.05). Conclusion:The risk of surgical treatment for ureteral calculi patients with COVID-19 infection is high, The treatment of them should mainly be conservative treatment, and operation should be performed after COVID-19 infection is cured.

Objective:To explore the risk factors for recurrence of intussusception in children after successful ultrasound-guided saline enema reduction.Methods:The clinical and follow up data of 355 hospitalized children with intussusception at the First Affiliated Hospital of Zhengzhou University from Feb 2018 to Feb 2023 were reviewed.Patients were divided into two groups by recurrence develped and the differences were compared, Data with significant differences were incorporated into multi-factor logistic analysis.Results:The overall recurrence rate was 15.8% (56/355). By univariate variable analysis model, there were statistically significant differences between the two groups in age, previous intussusception history, vomiting, maximum diameter of concentric circles shown by ultrasound, and concurrent bowel organic diseases (lead points) (all P<0.05). In multivariate Logistic regression model, age, previous intussusception history, maximum diameter of concentric circles, and lead points were independent risk factors for recurrent intussusception after saline enema.The optimal cut-off values for age and maximum diameter of concentric circles were 2 years and 33.5 mm, respectively, according to ROC curve analysis. Conclusion:Age older than 2 years, previous intussusception history, maximum diameter of concentric circles longer than 33.5 mm, and lead points are independent risk factors for recurrence after saline enema.

3ʹ-Hydroxy-4ʹ-methoxy-2-hydroxy-5-bromochalcone (hereinafter referred to as C13) is a novel chalcone derivative obtained in the process of structural modification of DHMMF, the antitumor active compound of Resina Draconis, in our laboratory. In this study, we investigated the effects of C13 on the proliferation and apoptosis of human gastric cancer HGC-27 and AGS cells and its potential mechanism of action. Firstly, through methyl thiazolyl tetrazolium (MTT), colony formation assay, and 5-ethynyl-2'-deoxyuridine (EdU) staining, we found that C13 inhibited the proliferation ability of human gastric cancer HGC-27 and AGS cells. Using flow cytometry and Western blot, it was found that C13 induced apoptosis in human gastric cancer HGC-27 and AGS cells, and up-regulated the protein level of cleaved poly ADP-ribose polymerase (cleaved-PARP). The results of RNA sequencing analysis showed that the Erb-b2 receptor tyrosine kinase 4/phosphoinositide 3-kinases/AKT (ErbB4/PI3K/AKT) signaling pathway may be involved in anti-gastric cancer activity of C13. Finally, the results of immunoblotting assay showed that C13 treatment down-regulated the protein levels of ErbB4 and phospho-ErbB4, as well as down-regulated the phosphorylation levels of PI3K and AKT in human gastric cancer HGC-27 and AGS cells, which verified the results from RNA-seq analysis. In conclusion, C13 inhibited the proliferation and induced apoptosis of human gastric cancer cells, which may be related to the down-regulation of ErbB4/PI3K/AKT signaling pathway. This study may provide a candidate drug for the treatment of gastric cancer.

Objective To observe the protective effects of codonopsis pilosulae polysaccharide on lung tissues in mice with acute lung injury(ALI)induced by lipopolysaccharide(LPS)and its mechanism.Methods Fifty male Kunming mice were randomly divided into control group,model group,dexamethasone group,codonopsis polysaccharide high-dose group(300 mg/kg)and codonopsis polysaccharide low-dose group(150 mg/kg).The ALI model was established by intraperitoneal injection of LPS.All mice were given gavage administration according to the grouping except for the control group.0.3 s force expiratory volume(FEV 0.3)and force spirometry(FVC)and their ratios were measured using multiparametric lung function test system.The histopathology change of mouse lung was detected by hematoxylin-eosin(HE)staining,and the classification and count of inflammatory cells in alveolar lavage fluid(BALF)was detected by Richter-Giemsa staining.Levels of IL-1β,IL-6,MPO and TNF-α were measured by ELISA in BALF,and Western blot was used to detect the protein expression level of p-p38,p-IκB-α and p-p65.Results Compared with those in the control group,lung histopathological damage was more pronounced in the model mice,with significantly lower FEV 0.3,FVC,FEV0.3/FVC assay value,but signifi-cantly higher lung tissue wet mass/dry mass(W/D),neutrophils,lymphocytes,IL-1β,IL-6,MPO,TNF-α,p-p38 MAPK,p-IκB-α,and p-p65(P<0.05);while codonopsis pilosulae polysaccharide could significantly reverse these effects.Conclusion Codonopsis pilosulae polysaccharide plays a protective role against LPS-induced ALI via inhibiting MAPK/NF-κB pathway to reduce the pathological damage of lung tissue,and the level of inflammatory factors,thus to improve lung function in ALI model mice.

Objective:To study the current status of longitudinal extrauterine growth restriction (EUGR) in extremely preterm infants (EPIs) and to develop a prediction model based on clinical data from multiple NICUs.Methods:From January 2017 to December 2018, EPIs admitted to 32 NICUs in North China were retrospectively studied. Their general conditions, nutritional support, complications during hospitalization and weight changes were reviewed. Weight loss between birth and discharge > 1SD was defined as longitudinal EUGR. The EPIs were assigned into longitudinal EUGR group and non-EUGR group and their nutritional support and weight changes were compared. The EPIs were randomly assigned into the training dataset and the validation dataset with a ratio of 7∶3. Univariate Cox regression analysis and multiple regression analysis were used in the training dataset to select the independent predictive factors. The best-fitting Nomogram model predicting longitudinal EUGR was established based on Akaike Information Criterion. The model was evaluated for discrimination efficacy, calibration and clinical decision curve analysis.Results:A total of 436 EPIs were included in this study, with a mean gestational age of (26.9±0.9) weeks and a birth weight of (989±171) g. The incidence of longitudinal EUGR was 82.3%(359/436). Seven variables (birth weight Z-score, weight loss, weight growth velocity, the proportion of breast milk ≥75% within 3 d before discharge, invasive mechanical ventilation ≥7 d, maternal antenatal corticosteroids use and bronchopulmonary dysplasia) were selected to establish the prediction model. The area under the receiver operating characteristic curve of the training dataset and the validation dataset were 0.870 (95% CI 0.820-0.920) and 0.879 (95% CI 0.815-0.942), suggesting good discrimination efficacy. The calibration curve indicated a good fit of the model ( P>0.05). The decision curve analysis showed positive net benefits at all thresholds. Conclusions:Currently, EPIs have a high incidence of longitudinal EUGR. The prediction model is helpful for early identification and intervention for EPIs with higher risks of longitudinal EUGR. It is necessary to expand the sample size and conduct prospective studies to optimize and validate the prediction model in the future.
