Objective To explore the impact of number of positive regional lymph nodes (nPRLN) in N1 stage on the prognosis of non-small cell lung cancer (NSCLC) patients. Methods Patients with TxN1M0 stage NSCLC who underwent lobectomy and mediastinal lymph node dissection from 2010 to 2015 were screened from SEER database (17 Regs, 2022nov sub). The optimal cutoff value of nPRLN was determined using X-tile software, and patients were divided into 2 groups according to the cutoff value: a nPRLN≤optimal cutoff group and a nPRLN>optimal cutoff group. The influence of confounding factors was minimized by propensity score matching (PSM) at a ratio of 1 : 1. Kaplan-Meier curves and Cox proportional hazards models were used to evaluate overall survival (OS) and lung cancer-specific survival (LCSS) of patients. Results A total of 1316 patients with TxN1M0 stage NSCLC were included, including 662 males and 654 females, with a median age of 67 (60, 73) years. The optimal cutoff value of nPRLN was 3, with 1165 patients in the nPRLN≤3 group and 151 patients in the nPRLN>3 group. After PSM, there were 138 patients in each group. Regardless of before or after PSM, OS and LCSS of patients in the nPRLN≤3 group were superior to those in the nPRLN>3 group (P<0.001). N1 stage nPRLN>3 was an independent prognostic risk factor for OS [HR=1.52, 95%CI (1.22, 1.89), P<0.001] and LCSS [HR=1.72, 95%CI (1.36, 2.18), P<0.001]. Conclusion N1 stage nPRLN>3 is an independent prognostic risk factor for NSCLC patients in TxN1M0 stage, which may provide new evidence for future revision of TNM staging N1 stage subclassification.

Objective To investigate the levels and clinical significance of serum secreted frizzled related protein 5(SFRP5),soluble cell adhesion molecule-1(sICAM-1),and Fetuin-B in patients with type 2 diabetes mellitus(T2DM)complicated with metabolic syndrome(MS).Methods A total of 142 T2DM patients ad-mitted in the Jiamusi Hospital of Infectious Diseases from April 2021 to April 2023 were selected as the study subjects.T2DM patients were grouped into MS group(n=75)and non MS group(n=67)based on whether they had MS.Enzyme linked immunosorbent assay(ELISA)was applied to determine the expression levels of serum SFRP5,sICAM-1,and Fetuin-B.Logistic regression was applied to analyze and determine the influen-cing factors of complicated MS in T2DM patients.The diagnostic efficacy of SFRP5,sICAM-1,and Fetuin-B in T2DM patients with MS was analyzed by establishing receiver operating characteristic(ROC)curve.Results There were statistically significant differences in HDL-C and HOMA-IR between the MS group and the non MS group(P＜0.05).Compared with the non MS group,the serum SFRP5 level in the MS group de-creased(P＜0.05),while the sICAM-1 and Fetuin-B levels increased(P＜0.05).Logistic regression analysis showed that SFRP5 and HDL-C were protective factors for the development of MS in T2DM patients(P＜0.05),while sICAM-1,Fetuin-B,and HOMA-IR were risk factors for the development of MS in T2DM pa-tients(P＜0.05).The combination of serum SFRP5,sICAM-1 and Fetuin-B had the largest area under the curve in diagnosing MS in T2DM patients,and its evaluation efficacy was obviously better than that of the in-dividual diagnosis of serum SFRP5,sICAM-1,and Fetuin-B(Zcombination-SFRP5=2.466,P=0.014,Zcombination-SICAM-1=3.550,P＜0.001,Zcombination-Fetuin-B=3.697,P＜0.001).Conclusion The serum SFRP5 level in patients with T2DM complicated with MS decreases,while sICAM-1 and Fetuin-B levels increase.The combination of the three has a good effect in diagnosing complicated MS in T2DM patients.

Objective: This study aimed to systematically evaluate potential causal relationships between nine cathepsins and female infertility using Mendelian randomization (MR) methods. Methods: A bidirectional MR analysis was conducted utilizing single nucleotide polymorphisms as instrumental variables to investigate the potential causal effects between nine cathepsins and female infertility. Genetic data on female infertility were sourced from the FinnGen study, and cathepsin-related data were obtained from genome-wide association studies datasets of European ancestry. Results: Elevated levels of cathepsin E were significantly and inversely associated with the risk of female infertility, suggesting a potential protective role. This finding was further supported by multivariable MR analysis. However, no significant associations were observed between the other eight cathepsins and female infertility. Conclusion This study represents the first systematic MR analysis to identify a potential protective effect of cathepsin E on female infertility.

The aim of this updated guideline is to provide comprehensive recommendations for the management of gout in patients with common comorbidities, such as chronic kidney disease(CKD), cardiovascular disease(CVD), diabetes, osteoarthritis(OA), and gastrointestinal disorders. This guideline was developed by a multidisciplinary expert panel consisting of specialists in endocrinology, rheumatology, nephrology, cardiology, gastroenterology, and methodology. The development process adhered to standard methodologies, including PICO(population, intervention, comparator, and outcomes) question deconstruction, systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation(GRADE) for evidence and recommendation evaluation, Delphi voting, and expert consensus. The guideline presents 26 evidence-based recommendations addressing 7 clinical questions for patients with hyperuricemia and gout in the context of comorbidities. Key recommendations include the maintenance of strict serum urate targets, particularly for patients with CKD stage≥3, chronic gouty arthritis, and OA, in order to prevent disease progression. In patients with CVD or diabetes, intra-articular triamcinolone is preferred over systemic glucocorticoids. Prioritized anti-inflammatory treatments for patients with CKD, gastrointestinal diseases and OA are recommended. The guideline also introduces emerging therapies, such as interleukin-1 inhibitors and selective urate transport inhibitors, as potential treatment options for refractory cases. The update offers a comprehensive, patient-centered approach to managing gout, particularly in individuals with associated comorbidities. Multidisciplinary collaboration and emerging new treatments and evidence ensure the optimization of the recommendations.

Objective To simulate modern social stress using a pre-pregnancy chronic mild stress(CMS)model and to explore the mechanisms of emotional,behavioral,and neurodevelopmental changes in male offspring of pre-pregnancy liver qi stagnation female mice through corticosterone(CORT)-brain-derived neurotrophic factor(BDNF)extracellular signal-regulated kinase(ERK)1/2 signaling cascade-mediated hippocampal injury.This study aimed to elucidate the impact of negative life events on offspring and the interventional mechanism of Shuyu Capsules.Methods CMS stress was used to induce pre-pregnancy depression in female rats(liver qi stagnation state),followed by intervention with Shuyu and fluoxetine capsules.After screening,male rats were mated and 12 male offspring from each group were selected for behavioral testing and detection of serum CORT levels by enzyme-linked immunosorbent assay.BDNF,ERK1/2,phospho(p)-ERK1/2,cAMP-response element binding protein(CREB),and p-CREB protein levels in the hippocampus were detected by Western Blot,and BDNF,ERK1,ERK2,and CREB mRNA levels in the hippocampus were detected by reverse transcription-polymerase chain reaction(RT-PCR),to verify the effects of pre-pregnancy CMS on the BDNF-ERK1/2-CREB signaling pathway and to investigate the key micro-mechanisms of Shuyu Capsules on emotional and learning memory-related behaviors of male offspring of females with pre-pregnancy liver qi stagnation syndrome.Results The distance,number of entries,and duration of stay in the central area in open-field experiments were significantly reduced in offspring in the model group(all P＜0.05).The escape latency during the exploration period of the water-maze experiment was significantly prolonged(P＜0.05)and the swimming distance,duration of the target quadrant,and number of platform crossings were significantly reduced(P＜0.05,P＜0.05,P＜0.01),the suspension time and frequency in the forced-swimming experiment were increased(P＜0.05,P＜0.01),and the incubation period was shortened(P＜0.05)in offspring in the model group.Prophylactic treatment with Shuyu Capsules and fluoxetine improved the depression-like behavior and cognitive impairment in the offspring in the model group.Biochemical tests showed that CORT levels were increased in the CMS model group(P＜0.05),BDNF,p-ERK1/2,and p-CREB protein levels in the hippocampus were decreased(all P＜0.05),and BDNF,ERK1,ERK2,and CREB mRNA levels were significantly reduced(P＜0.01,P＜0.05,P＜0.01,P＜0.05).Treatment with Shuyu Capsules and fluoxetine increased the CORT content and BDNF,ERK1/2,and CREB protein and mRNA levels in male offspring to varying degrees.Conclusions High levels of CORT in offspring act selectively on the hippocampus,exerting adverse effects on the emotional and learning memory functions of rats by downregulating the BDNF-ERK1/2 signaling cascade.The Chinese medicine Shuyu Capsules can reduce the impact of an adverse intrauterine environment on offspring development by correcting abnormal levels and pathways of glucocorticoids.
