To investigate the association between neutrophil to lymphocyte ratio (NLR) andestimated glomerular filtration rate (eGFR) in patients with diabetes using large-scale data. Across-sectional analysis was conducted using data from diabetic patients in the National Health and Nutrition Examination Survey database from 2009 to 2014. Differences in NLR between patients with and without chronickidney disease (CKD) were compared. Pearson correlation analysis and multiple linear regression models wereapplied to assess the relationship between NLR and eGFR. A total of 857 diabetic patients were included, with 190 (22.2%) having CKD and 667 (77.8%) without CKD. NLR was significantly higher in patients with CKD compared to those without CKD (2.94±1.69 vs.2.36±1.98, NLR is independently negatively associatedwith eGFR in diabetic patients, demonstrating potential clinical value as an indicator of kidney function declineand CKD risk in this population.

Chronic atrophic gastritis (CAG), a common digestive system disease, has an unclear pathogenesis. Currently, it is mostly believed to be related to Helicobacter pylori (Hp) infection, immune factors, dietary factors, bile reflux, long-term use of antibiotics and anti-inflammatory drugs, and other factors. Ferroptosis is a regulated cell death mechanism that is iron-dependent and characterized by disruption of iron metabolism and accumulation of lipid peroxides. More and more studies have found that ferroptosis is closely related to the onset of CAG. Professor LI Diangui, a master of traditional Chinese medicine, first proposed the turbid toxin theory, which holds that spleen deficiency and turbid toxin is the main pathogenic mechanism of CAG. Abnormal iron metabolism regulation is a prerequisite for the accumulation of turbid toxin in CAG, and ferroptosis is in accordance with the pathogenic mechanism (spleen deficiency and turbid toxin) of CAG. This article explores the pathological mechanism of spleen deficiency and turbid toxin in CAG from the perspectives of iron metabolism, oxidative stress, and lipid peroxidation, providing theoretical support of traditional Chinese medicine for the modern research on CAG. It enriches the modern scientific connotation of the turbid toxicity theory and provides new ideas and breakthrough points for the clinical treatment of CAG.

【Objective】 To explore the expression of USP9X in platelets and its effect on platelet function. 【Methods】 The expression of USP9X in human and mouse was evaluated by PCR and Western blot. Platelets from young and old mice were separated and prepared, and the expression of USP9X was detected. USP9X inhibitos were used to assess the regulation of USP9X in platelet function, including aggregation, ATP release and spreading. Platelet lysates were collected in different time points to evaluate the change of phosphorylation of Akt in USP9X inhibitors treated platelets. 【Results】 Both human and mouse platelets expressed USP9X. Compared to the young mice, the old mice showed significantly enhanced expression of USP9X(P<0.05). To assess the effect of USP9X on platelet function, USP9X inhibitor was used to pre-incubate platelets for 30 min and platelet function were examined later. Results showed that USP9X inhibitor significantly decreased platelet activation including aggregation, ATP release and spreading(P<0.05). Compared to the control group, the inhibitor treated group showed a significant decrease in the spreading area after 45 minutes. The Western blot results showed a significant decrease in Akt phosphorylation levels of platelets in the USP9X inhibitor treated group. 【Conclusion】 Both human and mouse platelet express USP9X, and inhibition of USP9X decreased platelet function including aggregation, ATP release and spreading. USP9X can also influence the phosphorylation of Akt. The inhibitor of USP9X may become a potential therapeutic target for thrombosis intervention.

ObjectiveTo investigate the therapeutic effect and mechanism of coptisine on chronic atrophic gastritis (CAG) in rats based on the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. MethodA CAG rat model was induced by multiple factors, including sodium salicylate, N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), and irregular feeding. The successfully modeled rats were randomly divided into the model group, folic acid group, and high- and low-dose coptisine groups. The high- and low-dose coptisine groups were given coptisine (50, 10 mg·kg-1, respectively), and the folic acid group was given folic acid at 2 mg·kg-1 for 60 days. The pathological changes were detected by hematoxylin-eosin (HE) staining. The ultrastructure of gastric mucosal cells was observed by electron microscopy. Serum pepsinogen Ⅰ (PGⅠ), pepsinogen Ⅱ (PGⅡ), and PGⅠ/PGⅡ ratio (PGR) were detected by immunoturbidimetry. Serum gastrin-17 (G-17) level was detected by radioimmunoassay. The content of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in serum of rats was detected by enzyme-linked immunosorbent assay (ELSIA). Western blot analysis was used to detect the expression levels of TGF-β1, PI3K, phosphorylated-Akt (p-Akt), mTOR, and phosphatase and tensin homolog deleted on chromosome 10 (PTEN) in gastric mucosa. The mRNA levels of TGF-β1, PI3K, Akt, mTOR, PTEN, microtubule-associated protein light chain 3Ⅱ (LC3Ⅱ), and Beclin-1 were detected by real-time quantitative polymerase chain reaction (Real-time PCR). ResultCompared with the normal group, the model group showed atrophy and reduced number of intrinsic glands in the gastric mucosal tissues, as well as inflammatory cell infiltration. The ultrastructure of gastric mucosal cells in the model group displayed nuclear condensation, reduced and swollen mitochondria, and abnormal structure. The serum levels of G-17, PGⅠ, PGR, and the protein and mRNA levels of PTEN in gastric tissues were significantly lower in the model group (P<0.01), while serum levels of IL-6, IL-1β, TNF-α, and the protein and mRNA levels of TGF-β1, PI3K, Akt, and mTOR in gastric tissues were significantly higher (P<0.01). Compared with the model group, various drug intervention groups showed different degrees of improvement in pathological damage and gastric mucosal cell ultrastructure, significantly increased serum levels of G-17, PGⅠ, and PGR (P<0.05,P<0.01), and significantly decreased levels of IL-6, IL-1β, and TNF-α (P<0.05,P<0.01). The high-dose coptisine group significantly downregulated the protein and mRNA levels of TGF-β1, PI3K, Akt, and mTOR (P<0.05,P<0.01). ConclusionBerberine has a therapeutic effect on CAG in rats, possibly exerting a protective effect on gastric mucosa by inhibiting inflammation and blocking the PI3K/Akt/mTOR signaling pathway.

Objective:To explore the psychological experience and demand of parents of children with delayed recovery after congenital heart disease surgery.Methods:This study adopted phenomenological research methods from qualitative research. Using the purposive sampling method, parents of postoperative delayed recovery children with congenital heart disease who met the inclusion criteria were selected as the research objects from October to November 2019 at Fuwai Hospital, Chinese Academy of Medical Sciences. Semi-structured interviews were conducted with the parents of the children, and the data were analyzed by Colaizzi 7-step analysis method.Results:Finally, 13 parents of children with delayed recovery after congenital heart disease surgery were included. According to the interview results, four themes were extracted, which were negative psychological experience of parents of children with delayed recovery, positive psychological experience and expectation change of parents, heavy economic burden of parents and diversified needs of parents.Conclusions:During the delayed recovery period, psychological experience of parents is complex and their needs are diverse. The nursing staff should identify and pay attention to the causes of the negative psychological experience of the parents of the children, timely channel their negative emotions and strengthen the positive psychological experience in many aspects. They can assist parents to seek social help to reduce physical and mental pressure and meet the diverse needs of parents by providing high-quality nursing services and multi-channel information support.

Membranous nephropathy(MN)is the predominant cause of primary nephrotic syn-drome(NS)among adults.The identification of PLA2R as target antigen has brought about a pro-found transformation in the management of MN,offering a basis for the utilization of B-cell deplet-ing agents such as rituximab(RTX).The question of whether early intervention targeting antibodies can effectively impede the progression of MN,contrib-uting to enhanced disease control and long-term renal outcomes for patients,remains further explo-ration.We analyzed demographic data,laboratory parameters,and renal involvement in 13 patients with PLA2R antibody-related MN who received at least one RTX treatment at our center from Octo-ber 2019 to March 2023.Early-stage medium-to-high-risk MN was defined as baseline or admission anti-PLA2R antibody levels exceeding 50 RU/mL,ex-cluding patients who already presented with ne-phrotic syndrome at baseline.The median duration of MN at the initiation of the first RTX treatment was 4.1 months(IQR 1-7.7),and the median follow-up time after RTX therapy was 27 months(IQR 23-45).All patients had commenced renin-angiotensin system inhibitors before receiving RTX.Following RTX therapy,none of the 13 patients progressed to NS during the follow-up period,and 12 patients achieved complete or partial remission at the 2-year follow-up or the last visit.No deaths,severe infections,or other serious adverse reactions oc-curred during the follow-up period.In conclusion,RTX demonstrates favorable efficacy and safety in early-stage,medium-to-high-risk MN patients.Initi-ating antibody clearance therapy in these patients may be beneficial for long-term disease control and distant renal outcomes.
