OBJECTIVE To study the protective effect and potential mechanism of chikusetsu saponin Ⅳ a （chsⅣ） on renal function in diabetic nephropathy （DN） model rats. METHODS DN rat model was established by high-fat diet combined with streptozotocin injection. Thirty-six model rats were randomly divided into model group （i.g. administration of normal saline， high-fat diet）， chsⅣ low-dose and high-dose groups （i.g. administration of 90， 180 mg/kg chsⅣ， high-fat diet）， with 12 rats in each group. Additionally， 10 normal rats were set as the control group （i.g. administration of normal saline， regular diet）. From the 5th to the 12th week after streptozotocin injection， they were given intragastric administration of relevant drug or normal saline， once a day. After the last medication， the levels of fasting blood glucose， fasting insulin， blood urea nitrogen， serum creatinine and urine protein as well as the levels of reduced glutathione （GSH）， superoxide dismutase （SOD） and malondialdehyde （MDA） in renal tissues were measured. Additionally， the insulin resistance index was calculated. Hematoxylin-eosin， periodic acid-Schiff， and Masson staining techniques were employed to examine the histopathological alterations in the renal tissue. The expressions of Notch signaling pathway-related proteins in renal tissue were detected by immunohistochemical staining and Western blot methods. RESULTS Compared with model group， the histomorphological of renal tissues in the chsⅣ low- and high-dose groups were significantly improved， with significant decreases in renal histological scores， mesangial expansion index， and glomerulosclerosis scores （ P ＜0.05）； the levels of fasting blood glucose， fasting insulin， blood urea nitrogen， serum creatinine， urine protein and homeostasis model assessment for insulin resistance， as well as MDA content， the expression levels of Notch1， Notch intracellular domain， hairy and enhancer of Split 1 and Delta-like protein 1 in renal tissue were all significantly decreased （ P ＜0.05）. The levels of GSH and SOD in renal tissue were significantly elevated （ P ＜0.05）. Moreover， the improvement in these indicators was significantly more pronounced in the chsⅣ high-dose group compared to the chsⅣ low-dose group （ P ＜0.05）. CONCLUSIONS ChsⅣ can ameliorate renal pathological damage and functional impairment in DN rats. Its underlying mechanisms include restoration of glucose homeostasis and insulin sensitivity， attenuation of renal oxidative stress， and suppression of aberrant Notch signaling pathway activation.

OBJECTIVE To systematically evaluate the correlation between dynamic changes in inflammatory markers during treatment with epidermal growth factor receptor-tyrosine kinase inhibitors （EGFR-TKIs） in non-small cell lung cancer （NSCLC） patients and therapeutic efficacy， with the aim of providing evidence-based support for clinical prognosis assessment and treatment strategy adjustment. METHODS Databases including PubMed， Embase， Cochrane Library， CNKI， Wanfang Data， and CBM were searched from the inception to July 20， 2025. Following literature screening， data extraction and quality assessment， descriptive analysis was conducted on the outcomes of included studies. RESULTS A total of eight studies were included to analyze the correlation of 6 inflammatory markers before and after treatment with EGFR-TKIs with therapeutic efficacy. The risk of bias assessment identified six high-quality studies and two moderate-quality studies. Among these studies， seven studies demonstrated that lower levels of neutrophil-to-lymphocyte ratio （NLR）， derived neutrophil-to-lymphocyte ratio （dNLR）， platelet-to-lymphocyte ratio （PLR）， and monocyte-to-lymphocyte ratio （MLR）， higher lymphocyte-to-monocyte ratio （LMR） before treatment， as well as decreased NLR and MLR and increased LMR after treatment were associated with longer median progression-free survival. Five studies indicated that lower levels of NLR， dNLR， PLR， and interleukin-6 （IL-6）， higher LMR before treatment as well as decreased NLR and dNLR and increased LMR were associated with longer median overall survival. Three studies indicated that lower levels of IL-6 were associated with a higher objective response rate， while the association of these markers after treatment remained controversial； another study showed that an early decline in NLR， MLR， and PLR after treatment may be associated with objective response benefit. CONCLUSIONS Lower inflammatory levels during EGFR-TKIs therapy correlate with better therapeutic efficacy in NSCLC patients.

Approximately 60% of colorectal cancer (CRC) patients exhibit TP53 mutations, which are strongly associated with tumor progression, chemotherapy resistance, and an unfavorable prognosis. However, targeting p53 has historically been challenging, and currently, there are no approved p53-based therapeutics for clinical use worldwide. In this study, we discovered that ubiquitin carboxyl terminal hydrolase L3 (UCHL3) plays a crucial role in high-level glycolysis, enhanced stem-like properties, and 5-fluorouracil (5-FU) chemoresistance in TP53-mutant CRC by exerting its deubiquitinating enzyme activity to stabilize α-enolase (ENO1) protein. Notably, we identified a newly Food and Drug Administration (FDA)-approved drug, pacritinib, that potently suppresses UCHL3 expression by blocking the janus kinase 2 (JAK2)-signal transducer and activator of transcription 3 (STAT3) pathway in TP53-mutant CRC. Furthermore, Pacritinib was demonstrated to effectively inhibit glycolysis and improve the sensitivity to 5-FU chemotherapy in TP53-mutant CRC. Our findings suggest that targeting the JAK2-STAT3-UCHL3-ENO1 axis is a promising strategy to suppress glycolysis and enhance the efficacy of 5-FU chemotherapy in TP53-mutant CRC. Pacritinib shows potential for clinical application in the treatment of TP53-mutant CRC.

Objective To evaluate the therapeutic efficacy for surgical treatments among patients with hepatic cystic echinococcosis in Gansu Province from 2006 to 2023, so as to provide insights into optimization of the diagnosis and treatment strategies against hepatic cystic echinococcosis. Methods The demographic and clinical data of all echinococcosis cases included in central government fiscal transfer payment program for echinococcosis control and undergoing surgical treatments in Gansu Province from 2006 to 2023 were captured. Hepatic cystic echinococcosis patients with complete medical records and follow-up data were included in the study, and patients’ characteristics, including hospital where patients received diagnosis and treatment, methods of case identification, year of surgery, classification of lesions, number of lesions, size of lesions, course of disease, surgical methods, and post-surgical follow-up data. The cure and recurrence of hepatic cystic echinococcosis were evaluated according to the Guidelines for Management of Echinococcosis Patients in the Central Government Fiscal Transfer Payment Program, and the cure and recurrent rates were calculated. Results Data were collected from 1 686 surgical patients with hepatic cystic echinococcosis. According to the inclusion and exclusion criteria, 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments were included during the period from 2006 to 2022, including 1 166 cured patients (95.42%) and 88 patients with postsurgical recurrence (7.20%), and the cure rate of surgical treatments appeared a tendency towards a rise among patients with hepatic cystic echinococcosis from 2008 to 2022 (χ²_trend = 19.39, P < 0.05). The cure rates of hepatic cystic echinococcosis were 100% (177/177), 94.81% (128/135) and 94.62% (861/910) among patients detected through regular physical examinations, screened by the central government fiscal transfer payment program for echinococcosis control, and those who passively sought healthcare services, respectively (χ² = 9.95, P < 0.05). The cure rates of hepatic cystic echinococcosis were 95.96% (1 046/1 090) among patients with a disease course of 2 years and less and 90.90% (120/132) among patients with a disease course of over 2 years (χ² = 6.87, P < 0.05), and there were significant differences in the cure rates among patients with hepatic cystic echinococcosis in terms of number of lesions (χ² = 24.44, P < 0.05) and surgical methods (P < 0.05). The cure rate of hepatic cystic echinococcosis patients was significantly higher following initiation of the central government fiscal transfer payment program for echinococcosis control (96.06%, 1 096/1 141) than before the program (86.42%, 70/81) (χ² = 16.06, P < 0.05), and the cure rate of hepatic cystic echinococcosis patients was significantly higher in designated hospitals (96.48%, 741/768) than in non-designated hospitals (93.37%, 366/392) (χ² = 5.78, P < 0.05). The median follow-up period was 4 (interquartile range, 7) years among 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments. The recurrent rate of hepatic cystic echinococcosis appeared a tendency towards a decline from 2008 to 2022 (χ²_trend = 36.86, P < 0.05), with a reduction from 23.08% (9/39) in 2008 to 1.85% (1/54) in 2021, and the post-surgical recurrence rate of hepatic cystic echinococcosis was lower following initiation of the central government fiscal transfer payment program for echinococcosis control (5.87%, 67 / 1 141) than before the program (25.93%, 21/81) (χ² = 45.51, P < 0.05). In addition, the post-surgical recurrence rate of hepatic cystic echinococcosis was higher in non-designated hospitals (10.46%, 41/392) than in designated hospitals (5.60%, 43/768) (χ² = 9.12, P < 0.05), and there was a significant difference in the post-surgical recurrence rate among patients with hepatic cystic echinococcosis in terms of surgical methods (P < 0.05), with the highest recurrence rate (11.54%) seen among patients undergoing percutaneous fine-needle aspiration of cyst fluids-based surgical procedures (P < 0.05). Conclusion Since the initiation of the central government fiscal transfer payment program for echinococcosis control in Gansu Province in 2006, an increase in the surgical cure rate and a reduction in the recurrence of hepatic cystic echinococcosis had been found among patients with hepatic cystic echinococcosis, indicating a high overall therapeutic efficacy.

Objective:To explore the dynamic relationship between college students' online psychological needs satisfaction dominance(OPNSD)and phubbing.OPNSD refers to the tendency of individuals to fulfill their basic psychological needs primarily through online environments.Methods:A sample of 340 college students from a university in Beijing participated in two data collections(T1 and T2)at 3-month intervals.OPNSD was calculated as the difference between scores on the Need Satisfaction Perceived Online Scale(NSPOS)and the Basic Need Sat-isfaction in General Scale(BNSGS).Phubbing and its 4 dimensions(self-isolation,nomophobia,interpersonal con-flict,and problem acknowledgment)were measured with the Generic Scale of Phubbing(GSP).A cross-lagged panel model was used to explore the relationship between the online psychological needs satisfaction dominance and phubbing.Results:Significant simultaneous(r=0.60,P＜0.001)and successive temporal(r=0.56,P＜0.001)correlations were observed between the OPNSD score and GSP score.T1 OPNSD score was positively associated with T2 GSP score in the dimensions of self-isolation,nomophobia,and interpersonal conflict(β=0.14,0.10,0.11;P＜0.001 or P＜0.05),but showed no association with the problem acknowledgement dimension score(β=0.07,P＞0.05).However,the four dimensions of T1 GSP score were not associated with T2 OPNSD score(Ps＞0.05).Conclusion:This study suggests that college students' online psychological needs satisfaction dominance positively predicts phubbing,highlighting the critical influence of online environments on mobile phone behaviors.

BACKGROUND:The blood-brain barrier is an important structure that protects the central nervous system,and the study of the effects of high glucose on the blood-brain barrier is important for the prevention of high glucose-induced damage to the central nervous system.OBJECTIVE:To investigate the potential effect of high glucose on the blood-brain barrier function of hCMEC/D3 human brain microvascular endothelial cells.METHODS:hCMEC/D3 cells were cultured in regular sugar medium(glucose concentration of 25 mmol/L)and high-sugar medium(glucose concentration of 55 mmol/L).The morphology of cells in each group was observed by light microscopy.CCK-8 assay was used to detect changes in cell viability.A monolayer blood-brain barrier model was established using hCMEC/D3 cell line with Transwell chamber device.Changes in cell transmembrane resistance were monitored daily.The permeability of cell monolayers was detected by phenol red permeability.Flow cytometry was used to detect the apoptosis rate of the cells.Western blot assay was used to detect the expression of Bcl-2,Bax,Caspase-3,ZO-1,Occludin,Claudin-1,and histone deacetylase 4.The levels of histone deacetylase in cell supernatant were detected by ELISA.The expression of histone deacetylase 4 in cells was detected by immunofluorescence.RESULTS AND CONCLUSION:(1)The cell viability of high sugar group was significantly lower than that of control group(P＜0.000 1).(2)The cells of the control group were in a good growth state,interwoven into a dense mesh,with interconnections between synapses.The cell growth of high glucose group was suppressed,and the connection of inter-cellular synapses was reduced.(3)Compared with the control group,the transmembrane resistance value of the high glucose group was reduced(P＜0.05);phenol-red permeability of the monolayer cell membrane was increased(P＜0.05);cell apoptosis rate was increased(P＜0.01);the expression of Bax protein was increased(P＜0.000 1);the expression of Caspase-3 protein had no significant change(P＞0.05);the expression of Bcl-2,ZO-1,Occludin,Claudin-1,and histone deacetylase 4 proteins was decreased(P＜0.01,P＜0.001,P＜0.01,P＜0.000 1,P＜0.01);the fluorescence expression of histone deacetylase 4 was decreased(P＜0.001)in the high glucose group.(4)The level of histone deacetylase 4 in the cell supernatant of the high glucose group was lower than that of the control group(P＜0.05).The results show that high glucose induces the increased apoptosis and enhances permeability of hCEMCE/D3 cells,and its mechanism may be related to the decreased expression level of histone deacetylase 4.

Objective To explore the experiences of children with Crohn's disease and their parents regarding the exclusion diet,and to provide a basis for formulating personalized dietary guidance programs.Methods A total of 12 children with Crohn's disease and their parents,hospitalized in the Department of Gastroenterology at a tertiary children's hospital in Guangzhou from June to December 2023,were selected as research subjects using objective sampling.Semi-structured interviews were conducted,and the data were analyzed and refined using Colaizzi's seven-step analysis method.Results Totally 3 themes and 14 sub-themes were extracted.①Lack of cognition and trust in Crohn's disease exclusion diet(unfamiliarity with the contents of the diet,misunderstanding of the diet's preparation,inadequate response to daily exclusion diet practices,parents' distrust in the exclusion diet).②The practical challenges of the Crohn's disease exclusion diet(the challenge of personal dietary preferences,the challenge of family meal preparation,the challenge of school feeding,food intolerance,feelings of monotony and weariness following the exclusion diet).③Innovations in practicing the Crohn's disease exclusion diet(managing taste fatigue,managing visual fatigue,innovative cooking methods,prioritizing exclusive enteral nutrition followed by the exclusion diet,overcoming the desire for universal food).Conclusion Children with Crohn's disease and their parents exhibit insufficient cognition and trust in the exclusion diet and face various challenges in practice.Clinical medical staff should adopt personalized coping strategies tailored to the specific circumstances of each child.
