ObjectiveTo evaluate the clinical efficacy and safety of Baoshen prescription in the treatment of stage Ⅳ diabetic nephropathy （DN） in the patients with syndromes of Qi-Yin deficiency and kidney collateral stasis and obstruction， and to explore the mechanism of this prescription delaying the disease progression. MethodsA randomized， controlled， double-blind， multicenter clinical trial was conducted， in which 94 stage Ⅳ DN patients with syndromes of Qi-Yin deficiency and kidney collateral stasis and obstruction were randomly assigned into Baoshen prescription and control groups （47 cases）. The treatment lasted for 12 weeks. The primary efficacy indicators were mainly renal function indexes， including urine albumin-to-creatinine ratio （UACR）， 24-hour urine total protein （24 h-UTP）， serum creatinine （SCr）， and estimated glomerular filtration rate （eGFR）. The secondary efficacy indicators were metabolic memory of hyperglycemia， podocyte epithelial-to-mesenchymal transdifferentiation-related indexes， and TCM syndrome score. ResultsAfter 12 weeks of treatment， the Baoshen prescription group showed lowered levels of advanced glycation end products （lgAGEs）， connective tissue growth factor （CTGF）， type Ⅳ collagen （Col-Ⅳ）， receptor of AGEs （RAGE）， urinary fibroblast-specific protein-1 （FSP-1）， UACR， 24 h-UTP， and glycated hemoglobin （HbAlc） （P<0.05）， and an upward trend of miR-21 mRNA. The control group showed elevated levels of SCr and UREA and lowered levels of urinary FSP-1， eGFR， and HbAlc （P<0.05）. After treatment， the Baoshen prescription group had lower levels of lgAGEs， CTGF， urinary FSP-1， SCr， UACR， and 24 h-UTP and higher levels of Col-Ⅳ and eGFR than the control group （P<0.05）. In addition， the Baoshen prescription group showed statistically significant differences in SCr， eGFR， UACR， and 24 h-UTP before and after treatment （P<0.05）. ConclusionBaoshen prescription can effectively improve the renal function， reduce the urinary protein level， and alleviate clinical symptoms in stage Ⅳ DN patients with syndromes of Qi-Yin deficiency and kidney collateral stasis and obstruction. The mechanism may be related to the metabolic memory of hyperglycemia and epithelial-to-mesenchymal transdifferentiation of podocytes.

OBJECTIVE To know about the perception and current status of drug risk management among pharmacists in Chinese medical institutions， providing insights and recommendations for enhancing the drug risk management system in medical institutions. METHODS A questionnaire survey was conducted across 28 provinces， cities， and autonomous regions； stratified radom sampling was employed to study the population of medical workers and pharmaceutical professionals in medical institutions nationwide. The survey included information on the survey population， the current status of drug risk management implementation in medical institutions， the cognition， definition and process of drug risk management related concepts， and the content and mode of drug risk management work in medical institutions. Finally， suggestions were collected from various medical institutions on the system construction of drug risk management. Descriptive statistical analysis was adopted to summarize the obtained data. RESULTS A total of 446 questionnaires were collected in this survey， including 420 valid questionnaires and 26 invalid questionnaires. The questionnaire collection rate was 100%，and the effective rate was 94.17%. 51.19% of the respondents No.2020YFC2009001）。 based their understanding of drug risk management on Management Measures for Adverse Drug Reaction Reports and Monitoring， while 87.38% recognized the need for drug risk management throughout the drug use process. 63.33% of the participants stated that their medical institutions had dedicated positions related to drug risk management， with the highest proportion （72.17%） was in third-grade class A medical institutions. 66.43% reported implementing risk management across all drug use stages. Suggestions for the development of drug risk management systems in medical institutions by the research participants focused on enhancing guiding documents， clarifying concepts， establishing information-sharing mechanisms. CONCLUSIONS The overall awareness of drug risk management in China’s medical institutions is high， with practices in place across various stages in multiple forms. However， there remains a need to strengthen institutional documents， management regulations， system development， and information-sharing mechanisms to improve collaborative governance， improve drug management levels， and ensure patient safety.

ObjectiveThe differential expression of microRNAs （miRNAs） between the active stage and the remission stage of ulcerative colitis （UC） was analyzed by bioinformatics method， and the regulatory relationship was constructed by screening the differentially expressed genes （DEGs）. The mechanism of Xizhuo Jiedu recipe in the treatment of UC was speculated and verified by animal experiments. MethodThe miRNAs data set of colonic mucosa tissue of UC patients was obtained from the gene expression database （GEO）， and the most differentially expressed miRNAs were screened by GEO2R， Excel， and other tools as research objects. TargetScan， miRTarbase， miRDB， STRING， TRRUST， and Matescape databases were used to screen key DEGs， predict downstream transcription factors （TFs）， gene ontology （GO）， and conduct Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis. The key signaling pathways were selected for animal experiments. In animal experiments， the UC mouse model was prepared by making the mouse freely drink 2.5% dextran sodium sulfate （DSS）. Xiezhu Jiedu recipe and mesalazine were given by gavage for seven days， and the inflammatory infiltration of colonic mucosa was observed by hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of miR-155-5p in colon tissue. Immunohistochemistry and Western blot were used to detect the protein expression levels of cytokine signal transduction inhibitor （SOCS1）， phosphorylated transcriptional signal transductor and activator 3 （p-STAT3）， phosphorylated Janus kinase 2 （p-JAK2）， and retinoic acid-associated orphan receptor-γt （ROR-γt）. The expression levels of transforming growth factor-β （TGF-β）， interleukin-17 （IL-17）， interleukin-6 （IL-6）， and interleukin-10 （IL-10） in serum were detected by enzyme linked immunosorbent assay （ELISA）. ResultThe GSE48957 dataset was screened from the GEO database， and miR-155-5p was selected as the research object from the samples in the active and remission stages. 131 DEGs were screened. The GO/KEGG enrichment analysis was closely related to biological processes such as positive regulation of miRNA transcription and protein phosphorylation， as well as signaling pathways such as stem cell signaling pathway， IL-17 signaling pathway， and helper T cell 17 （Th17） cell differentiation. The Matescape database was used to screen out 10 key DEGs， among which SOCS1 was one of the key DEGs of miR-155-5p. Further screening of the TFS of key DEGs revealed that STAT3 was one of the main TFs of SOCS1. The results of animal experiments showed that Xiezhu Jiedu Recipe could effectively down-regulate the mRNA expression of miR-155-5p and protein expression of p-STAT3， p-JAK2， and ROR-γt in colon tissue of UC mice and the expression of IL-17 and IL-6 in serum of UC mice， up-regulate the protein expression of SOCS1 and the expression of TGF-β and IL-10， increase the level of anti-inflammatory factors， and reduce inflammatory cell infiltration. ConclusionIt is speculated that Xizhuo Jiedu recipe may interfere with SOCS1 by regulating the expression of miR-155-5p in UC mice， inhibit the phosphorylation of STAT3， inhibit the differentiation of CD4⁺ T cells into Th17 cells， reduce the levels of pro-inflammatory factors （IL-17 and IL-6）， and increase the levels of anti-inflammatory factors （TGF-β and IL-10）. As a result， the inflammation of colon mucosa in UC mice was alleviated.

Objective To explore the current status and potential subtypes of frailty among family caregivers of patients with dementia,and to analyze the related influencing factors of different subtypes.Methods Dementia patients and their family caregivers in 8 community health service centers in Shanghai from June to October 2023 were recruited by convenience sampling.General information questionnaire,Tilburg Frailty Indicator(TFI),Pittsburgh Sleep Quality Index(PSQI),Self-Rating Depression Scale(SDS),Zarit Caregiver Burden Interview(ZBI),and Connor-Davidson Resilience Scale(CD-RISC)were conducted for investigation.Latent profile analysis was used to explore the potential subtypes of frailty among family caregivers of patients with dementia.The influencing factors associated with the potential subtypes were identified by univariate analysis and multivariate Logistic regression analysis.Results A total of 470 family caregivers of patients with dementia were surveyed,and 46.17％of them suffered from frailty.Frailty among family caregivers of patients with dementia can be classified into 3 potential subtypes:comprehensive-low frailty subtype(70.64％),psychosocial-medium frailty subtype(19.57％),and physical-high frailty subtype(9.79％).Family caregivers of patients with dementia who had poor sleep quality and suffered from 2 or more chronic diseases were more likely to be classified into the physical-high frailty subtype(P＜0.05).Family caregivers of patients with dementia who had higher levels of depression,lower mastery levels of caregiving knowledge and skills and spousal caregivers were more likely to be classified into the psychosocial-medium frailty subtype(P＜0.05).Family caregivers of patients with dementia who had higher levels of resilience were more likely to be classified into the comprehensive-low frailty subtype(P＜0.05).Conclusion The incidence of frailty among family caregivers of patients with dementia is at a high level with significant heterogeneity.It is suggested that medical staff should pay attention to the frailty of family caregivers,with a focus on family caregivers in the psychosocial-medium frailty subtype or physical-high frailty subtype,and take timely and targeted interventions according to the characteristics and influencing factors of different subtypes,so as to prevent or delay the occurrence and development of frailty.

【Objective】 To explore the value of preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in the prediction of inguinal lymph node metastasis of penile cancer to provide a new idea for the clinical evaluation. 【Methods】 A total of 48 patients with penile cancer who received surgical treatment in our hospital during Jan. 2016 and Dec. 2021 were selected and divided into the metastatic group (n=19) and non-metastatic group (n=29). The number of neutrophils, lymphocytes and platelets were recorded, and NLR and PLR were calculated. The value of NLR and PLR in predicting inguinal lymph node metastasis was analyzed with receiver operating characteristic (ROC) curve. The correlation between NLR and PLR was determined with Pearson correlation analysis. 【Results】 The levels of NLR and PLR were significantly higher in the metastatic group than in the non-metastatic group (P<0.05). ROC curve showed that the optimal cut-off value of NLR was 2.39, the area under the ROC curve (AUC) was 0.838 (95%CI:0.730-0.947), with sensitivity of 94.7% and specificity of 58.6%, respectively. The optimal cut-off value of PLR was 113.66, the AUC was 0.755 (95%CI:0.618-0.892), with sensitivity of 89.5% and specificity of 58.6%, respectively. The AUC of the two combined together was 0.851 (95%CI:0.747-0.956), with sensitivity of 89.5% and specificity of 69.0%. The Pearson correlation analysis showed that NLR was positively correlated with PLR in patients in both groups (r=0.504, r=0.645, P<0.05). 【Conclusion】 Preoperative NLR and PLR levels are significantly increased in patients with penile cancer,and the combination of the two indexes can predict the possibility of inguinal lymph node metastasis.

【Objective】 To investigate the association between genetic variations in the glucagon-like peptide-1 receptor (GLP-1R) gene and BP responses to sodium and potassium intake. 【Methods】 A total of 514 subjects from 124 families were recruited in Meixian County, Shaanxi Province, in 2004, resulting in the establishment of a "salt-sensitive hypertension study cohort" . The subjects followed a dietary regimen which involved a normal diet for 3 days, a low-salt diet for 7 days, a high-salt diet for 7 days, and a high-salt potassium-supplemented diet for 7 days. BP measurement was conducted at different intervention periods, and peripheral blood samples were collected. Additionally, eight single nucleotide polymorphisms (SNPs) of the GLP-1R gene were genotyped using the MassARRAY detection platform. 【Results】 The GLP-1R gene SNP rs9462472 exhibited a significant association with systolic BP, diastolic BP, and mean arterial pressure response to high-salt intervention. Similarly, SNP rs2268637 showed a significant association with systolic BP response to high-salt intervention. Furthermore, SNP rs2268637 was significantly associated with systolic BP and mean arterial pressure responses to high-salt plus potassium supplementation intervention. 【Conclusion】 Our findings indicate a significant association of genetic variations in the GLP-1R gene with BP responses to sodium and potassium intake. This suggests that the GLP-1R gene plays a role in the regulation of BP salt sensitivity and potassium sensitivity.
