Objective To investigate the mechanism of Astragali Complanati Semen in the prevention and treatment of hyperlipidemia;To provide theoretical basis for its clinical application.Methods The active components of Astragali Complanati Semen were retrieved and screened through TCMSP,TCMID and TDT databases to obtain the action targets of the active components.Hyperlipidemia targets were obtained through GeneCards,DisGeNET,and TTD databases,and the drug active component targets were intersected with hyperlipidemia targets.Cytoscape 3.9.1 software and STRING database were used to construct active component-target network and protein-protein interaction network,screening for major active components and core targets.GO and KEGG pathway enrichment analysis was performed using the DAVID database,and the CB-Dock platform was used for molecular docking.HepG2 cells were induced to construct a high-fat cell model using oleic acid and palmitic acid,and intervened with Astragali Complanati Semen freeze-dried powder solution.The mRNA expression of the core target was detected by RT-qPCR.Results A total of 10 active components of Astragali Complanati Semen and 67 potential action targets of hyperlipidemia were identified,involving signaling pathways such as AGE-RAGE,lipid metabolism,HIF-1,etc.Experimental results showed that intervention with Astragali Complanati Semen could reduce lipid accumulation in the high-lipid cell model,with an optimal intervention concentration of 500 μg/mL;RT-qPCR revealed significant down-regulation of TNFα,IL6,AKT1,PPARG,and other genes after intervention with Astragali Complanati Semen.Conclusion Astragali Complanati Semen exerts lipid-regulating effects through multiple targets and pathways,providing a basis for its application in the prevention and treatment of hyperlipidemia.

OBJECTIVE To explore the mechanism of Shaoyao gancao decoction in improving intestinal motility in rats with slow transit constipation(STC)by regulating acid-sensitive ion channel 3(ASIC3)/extracellular signal-regulated kinase(ERK)signaling pathway.METHODS SD rats were used to construct an STC model by gavage with compound diphenoxylate.The successfully modeled rats were randomly divided into model group,Shaoyao gancao decoction group(1.5 g/mL),lactulose group(208.4 mg/mL,positive control),and combined inhibition group(Shaoyao gancao decoction 1.5 g/mL+amiloride hydrochloride 20 μg/kg),with 12 rats in each group.Additionally,12 healthy rats were selected as the blank group.They were given relevant medicine once a day and continuously intervened for 14 days.After intervention,the intestinal propulsion function and visceral sensitivity of the model rats were detected.The expression of ASIC3 in the colon tissue of rats was observed by immunohistochemical staining.mRNA expressions of ASIC3,ERK1 and ERK2 as well as protein expressions of ASIC3,ERK1/2 and phosphorylated ERK1/2(p-ERK1/2)in colon tissue of rats were detected;the ultrastructural changes of the enteric nervous system(ENS)-interstitial cell of Cajal(ICC)-smooth muscle cell(SMC)network in the rat colon were observed under electron microscopy.RESULTS Compared with the model group,the intestinal propulsion rate of the Shaoyao gancao decoction group was significantly increased,while the visceral pain threshold was significantly decreased.The proportion of the positive area of ASIC3 in the colonic tissue was significantly increased.The relative mRNA expression levels of ERK1,ERK2,and ASIC3,as well as the relative protein expression levels of p-ERK1/2 and ASIC3,and the p-ERK1/2 to ERK1/2 in the colonic tissue,were all significantly increased(P＜0.05 or P＜0.01).Additionally,there was marked repair of the morphological structure of ICC and SMC,with closer gap junctions observed.Compared with the Shaoyao gancao decoction group,the combined inhibition group exhibited a diminished improvement in intestinal motility of rats,with statistically significant differences in the levels of some indicators(P＜0.05 or P＜0.01);the repairing of the morphological structure of ICC and SMC was notably attenuated.CONCLUSIONS Shaoyao gancao decoction can effectively improve the intestinal transmission function and promote intestinal repair in STC rats,and its mechanism may be related to regulating the balance of the ENS-ICC-SMC network mediated by the ASIC3/ERK signaling pathway,thus promoting intestinal motility and reducing visceral sensitivity.

Objective To study the economic burden caused by healthcare-associated infection(HAI)in patients with severe acute pancreatitis(SAP),and provide theoretical basis for formulating HAI prevention and control measures.Methods Patients with SAP discharged from a tertiary first-class hospital in Jiangxi Province from July 1,2023 to June 30,2024 were selected as the study subjects.Information including demographic characteristics,clinical data,and hospitalization expense were collected.Patients were divided into a HAI group and a non-HAI group according to HAI occurrence.A propensity score matching(PSM)method was used to conduct a 1∶2 ma-tching,and differences in the length of hospital stay and hospitalization expense between the two groups of patients after PSM were compared.Results A total of 709 patients were included in the analysis,out of which 65 cases ex-perienced HAI,with a HAI incidence of 9.17％.After PSM,all 65 patients in the HAI group were successfully matched.The length of hospital stay,total hospitalization expense,expenses of medication and hygiene product of patients in the HAI group were all higher than those in the non-HAI group,and differences were all statistically sig-nificant(all P＜0.001).Patients who experienced≥2 episodes of HAI had a higher economic burden than those who experienced only once(P＜0.05).HAI of bloodstream,abdomen,digestive system,and respiratory system significantly increased the economic burden of patients(all P＜0.05).Conclusion HAI in SAP patients can extend the length of hospital stay and increase economic burden of patients.Targeted infection prevention and control mea-sures should be formulated to reduce the incidence of HAI and save medical resources.

Objective The aim of this study is to understand the quality of the medical records front page,analyze the reasons,and propose targeted measures to continuously improve the quality of medical records front page,providing accurate and reliable data assurance for the DIP model.Methods A stratified sampling method was used to select 15 020 discharged medical records from a tertiary hospital in Guangzhou from 2022 to 2023.Senior coders performed quality control on the selected medical records front page using a double-person double-quality control mode.Data collection was conducted using Microsoft Excel 2007,and statistical description was performed using SPSS 26.0.Results The defect rate of the medical records front page in the stud-ied tertiary hospital in Guangzhou was 19.91％.The defect rates for non-surgical departments and surgical departments were 17.26％and 23.40％,respectively.There were 4,121 cases(49.28％)with information system transmission errors.The main defects affecting DIP inclusion in the medical records front page were the primary surgical or operative procedure name(903 ca-ses,10.80％)and the primary diagnosis(828 cases,9.90％).Conclusion The defect rate of the medical records front page in the studied tertiary hospital in Guangzhou is at a medium-to-high level,with prominent issues of information system transmis-sion errors and defects affecting DIP inclusion.Measures such as strengthening information construction,enhancing training and communication,and organizing medical records front page knowledge competitions should be implemented to improve the quality of medical records front page.

Objective To explore the clinical effects and influencing factors of recombinant human growth hormone(rhGH)treatment in pediatric patients with growth hormone deficiency.Methods The study subjects were pediatric patients with growth hormone deficiency,all of whom received a combination therapy of stanozolol tablets 2 mg(qd)and 0.1 U·kg-1·d-1 of recombinant human growth hormone injection for a continuous period of one year.After one year,the patients were divided into active group and invalid group based on clinical outcomes.Comparisons were made between the two groups in terms of height,annual growth velocity(GV)and height standard deviation score(HtSDS)before and after treatment,and safety evaluations were conducted.Multivariate Logistic regression analysis was used to identify factors that influenced the treatment outcomes in pediatric patients with growth hormone deficiency.Results After one year of treatment,a total of 93 cases pediatric patients were included in the analysis,with 62 cases in the active group and 31 cases in the invalid group.The heights of the patients before and after treatment were(119.40±2.48)and(129.08±2.37)cm,respectively;the GV were(3.08±0.39)and(7.34±1.02)cm·year-1,respectively;the HtSDS were-2.45±0.49 and-1.68±0.35,respectively,with statistically significant differences observed for all comparisons(all P＜0.05).In the active and invalid groups,the proportions of patients with GV＜3.0 cm·year-1 before treatment were 32.26％and 58.06％,respectively;the proportions of patients with peak growth hormone(GH)levels＜5.0 ng·mL-1 before treatment were 30.65％and 54.84％,respectively;the average maternal heights were(158.83±5.76)and(155.48±6.58)cm,respectively,with statistically significant differences observed for all comparisons(all P＜0.05).The results of the Logistic regression model showed that GV＜3.0 cm·year-1 before treatment,peak GH levels＜5.0 ng·mL-1 before treatment,and a shorter maternal height were independent risk factors for poor treatment outcomes with rhGH in pediatric patients with growth hormone deficiency(all P＜0.05).No severe adverse reactions occurred during the treatment of any patient;seven patients experienced pain at the injection site,one patient had a slight increase in blood glucose,and five patients had mild decreased appetite.The total incidence of adverse drug reactions were 13.98％(13 cases/93 cases).Conclusion Treatment with rhGH for pediatric patients with growth hormone deficiency can significantly improve height development and has good safety,but it is influenced by factors such as growth velocity,peak GH levels,and maternal height.

Objective:To understand the prevalence and related factors of three common chronic diseases, hyperlipidemia, hypertension and diabetes in HIV-infected persons.Methods:As of December 2023, HIV-infected persons >15 years old who are receiving antiviral therapy (ART) and follow-up in Henan Province were selected as the study objects. Questionnaires, physical examinations, and blood samples were collected to collect demographic information, ART, body weight, blood lipids, blood pressure, and blood sugar of HIV-infected persons. The logistic regression model was used to analyze the related factors of hyperlipidemia, hypertension and diabetes.Results:Among 4 023 HIV-infected patients, the prevalence rates of hyperlipidemia, hypertension, and diabetes were 64.47% (2 594/4 023), 16.80% (676/4 023), and 10.54% (424/4 023), respectively. Multivariate analysis showed that hyperlipidemia was positively associated with ≥40 years of age, overweight and obesity, two nucleoside reverse transcriptase inhibitors (NRTIs) + proteasome inhibitors (PIs) regimen and two NRTIs+ integrase inhibitor regimen, and negatively associated with low body weight. Hypertension was positively correlated with the age group ≥40 years old, family history of cardiovascular and cerebrovascular diseases, overweight and obesity, ART time ≥0.5 years, and negatively correlated with low body weight. Diabetes was positively associated with age group ≥40 years, family history of cardiovascular and cerebrovascular disease, overweight and obesity, and negatively associated with the use of two NRTIs+PIs treatment regimens.Conclusions:In 2023, the prevalence of hyperlipidemia, hypertension, and diabetes among HIV-infected people in Henan Province was relatively high, and the risk of common chronic diseases among those ≥40 years old, overweight and obese, and those with a family history of cardiovascular and cerebrovascular diseases was also relatively high. It is recommended to strengthen the prevention and management of common chronic diseases among HIV-infected people.

ObjectiveTo investigate the ameliorative effect of Xingpi capsules on functional dyspepsia（FD） and the potential mechanism. MethodsSixty SPF-grade male SD neonatal rats（7 days old） were randomly divided into the normal group（n=12） and the modeling group（n=48）， and the FD model was prepared by iodoacetamide gavage in the modeling group. After the model was successfully prepared， the rats in the modeling group were randomly divided into the model group， the low-dose and high-dose groups of Xingpi capsules（0.135， 0.54 g·kg^-1） and the domperidone group（3 mg·kg^-1）， with 12 rats in each group. Rats in the normal and model groups were gavaged with distilled water， and rats in the rest of the groups were gavaged with the corresponding medicinal solution， once a day for 7 d. The general survival condition of the rats was observed， and the water intake and food intake of the rats were measured， the gastric emptying rate and the small intestinal propulsion rate were measured at the end of the treatment， the pathological damage of the rat duodenum was examined by hematoxylin-eosin（HE） staining， and the expressions of colonic tight junction protein（Occludin） and zonula occludens protein-1（ZO-1） were detected by immunofluorescence. The differentially expressed genes in the duodenal tissues of the model group and the normal group， and the high-dose group of Xingpi capsules and the model group were detected by transcriptome sequencing after the final administration， and Gene Ontology（GO） and Kyoto Encyclopedia of Genes and Genomes（KEGG） enrichment analyses were carried out. The transcriptomic results were validated by Western blot， immunofluorescence， and real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the active ingredients of Xingpi capsules were screened for molecular docking with the key targets. ResultsCompared with the normal group， the general survival condition of rats in the model group was poorer， and the water intake， food intake， gastric emptying rate and small intestinal propulsion rate were all significantly reduced（P<0.05）， inflammatory infiltration was seen in duodenal pathology， and the fluorescence intensities of Occludin and ZO-1 in the colon were significantly reduced（P<0.01）. Compared with the model group， the general survival condition of rats in the high-dose group of Xingpi capsules improved significantly， and the water intake， food intake， gastric emptying rate and small intestinal propulsion rate were all significantly increased（P<0.05）， the duodenal pathology showed a decrease in inflammatory infiltration， and the fluorescence intensities of colonic Occludin and ZO-1 were significantly increased（P<0.01）. Transcriptomic results showed that Xingpi capsules might exert therapeutic effects by regulating the phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt） through the key genes such as Slc5a1， Abhd6. The validation results showed that compared with the normal group， the phosphorylation levels of PI3K and Akt proteins， the protein expression level of interleukin（IL）-1β， and the fluorescence intensities of IL-6 and IL-1β were significantly increased in the model group（P<0.05， P<0.01）， and the mRNA levels of Slc5a1， Abhd6， Mgam， Atp1a1， Slc7a8， Cdr2， Chrm3， Slc5a9 and other key genes were significantly increased（P<0.01）. Compared with the model group， the phosphorylation levels of PI3K and Akt， the protein expression level of IL-1β and the fluorescence intensities of IL-6 and IL-1β in the high-dose group of Xingpi capsules were significantly reduced（P<0.05， P<0.01）， and the mRNA levels of Slc5a1， Abhd6， Mgam， Atp1a1， Slc7a8， Cdr2， Chrm3 and Slc5a9 were significantly reduced（P<0.05）. Weighted gene co-expression network analysis and molecular docking results showed that E-nerolidol and Z-nerolidol in Xingpi capsules were well bound to ABDH6 protein， and linarionoside A， valerosidatum and senkirkine were well bound to Slc5a1 protein. ConclusionXingpi capsules can effectively improve the general survival and gastrointestinal motility of FD rats， its specific mechanism may be related to the inhibition of PI3K/Akt signaling pathway to alleviate the low-grade inflammation of duodenum， and E-nerolidol， Z-nerolidol， linarionoside A， valerosidatum and senkirkine may be its key active ingredients.
