ObjectiveTo investigate the impact of hepatocellular carcinoma （HCC） on the prognosis of patients with liver cirrhosis undergoing emergency endoscopic therapy for esophagogastric variceal bleeding， as well as independent influencing factors for the prognosis of liver cirrhosis patients without HCC after emergency endoscopic therapy for esophagogastric variceal bleeding. MethodsA total of 117 liver cirrhosis patients without HCC and 119 liver cirrhosis patients with HCC who underwent emergency endoscopic therapy for esophagogastric variceal bleeding in Renmin Hospital of Wuhan University from January 2017 to July 2023 were enrolled. Basic information including age and sex was collected from all patients， as well as the presence or absence of chronic diseases such as hypertension， diabetes， and coronary heart disease， the time of emergency endoscopy after admission， and liver function parameters including international normalized ratio， albumin， creatinine， sodium， total bilirubin， alanine aminotransferase， and aspartate aminotransferase （AST）. The independent-samples t test was used for comparison of normally distributed continuous variables between two groups， and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous variables between two groups； the chi-square test was used for comparison of categorical variables between groups. The covariance analysis and the multivariate logistic regression analysis were used for comparison of outcome variables after control of baseline variables， and the Kaplan-Meier survival curve was plotted for each group. The univariate and multivariate Cox regression analyses were performed for survival time in the non-HCC group to investigate the independent influencing factors for survival time， and then the Kaplan-Meier curve analysis and the log-rank test were performed to validate such independent influencing factors and analyze the independent influencing factors for secondary outcomes. ResultsCompared with the non-HCC group， the HCC group had significantly higher red blood cell transfusion units （6.00［2.00～9.00］ vs 4.00［1.75～7.00］， Z=-2.050， P=0.040， F=4.869， adjusted P=0.028）， a significantly shorter survival time （29.77±16.01 days vs 38.07±11.43 days， t=4.574， P<0.001， F=17.294， adjusted P<0.001）， and a significantly higher 5-day rebleeding rate （22.69% vs 6.84%， χ²=11.736， P<0.001， adjusted P=0.021）. The Kaplan-Meier curve analysis showed that the risk of 42-day mortality in the HCC group was 3.897 （95% confidence interval ［CI］： 2.338 ‍— 6.495， P<0.001） times that in the non-HCC group. The multivariate Cox regression analysis of the non-HCC group showed that the total length of hospital stay （hazard ratio ［HR］=0.793， 95%CI： 0.644 ‍— ‍0.976， P=0.029） was an independent protective factor for 42-day survival. The Kaplan-Meier curve analysis showed that a length of hospital stay of >9 days was beneficial for the prognosis of patients （HR=4.302， 95%CI： 1.439 — 12.870， P=0.037）. Blood sodium level （odds ratio ［OR］=0.523， 95%CI： 0.289 ‍— ‍0.945， P=0.032） and MELD-Na score （OR=0.495， 95%CI： 0.257 ‍— ‍0.954， P=0.036） were independent protective factors against 5-day rebleeding， while AST level was an independent risk factor for 5-day rebleeding （OR=1.023， 95%CI： 1.002 ‍— ‍1.043， P=0.028） and in-hospital death （OR=1.036， 95%CI： 1.001‍— ‍1.073， P=0.045）. ConclusionLiver cirrhosis patients with variceal bleeding and HCC tend to have a worse prognosis， and for the non-HCC group， in-hospital mortality rate increases with the increase in AST level. The total length of hospital stay is an independent protective factor for survival time in the non-HCC group， and it is recommended to appropriately prolong the length of hospital stay for such patients.

This study aims to systematically characterize the targeted effects of Quanduzhong Capsules on cartilage lesions in knee osteoarthritis by integrating spatial transcriptomics data mining and animal experiments validation, thereby elucidating the related molecular mechanisms. A knee osteoarthritis model was established using Sprague-Dawley(SD) rats, via a modified Hulth method. Hematoxylin and eosin(HE) staining was employed to detect knee osteoarthritis-associated pathological changes in knee cartilage. Candidate targets of Quanduzhong Capsules were collected from the HIT 2.0 database, followed by bioinformatics analysis of spatial transcriptomics datasets(GSE254844) from cartilage tissues in clinical knee osteoarthritis patients to identify spatially specific disease genes. Furthermore, a "formula candidate targets-spatially specific genes in cartilage lesions" interaction network was constructed to explore the effects and major mechanisms of Quanduzhong Capsules in distinct cartilage regions. Experimental validation was conducted through immunohistochemistry using animal-derived biospecimens. The results indicated that Quanduzhong Capsules effectively inhibited the degenerative changes in the cartilage of affected joints in rats, which was associated with the regulation of Quanduzhong Capsules on the thioredoxin-interacting protein(TXNIP)-NOD-like receptor family pyrin domain containing 3(NLRP3)-bone morphogenetic protein receptor type 2(BMPR2)-fibronectin 1(FN1)-matrix metallopeptidase 2(MMP2) signal axis in the articular cartilage surface and superficial zones, subsequently inhibiting cartilage matrix degradation leading to oxidative stress and inflammatory diffusion. In summary, this study clarifies the spatially specific targeted effects and protective mechanisms of Quanduzhong Capsules within pathological cartilage regions in knee osteoarthritis, providing theoretical and experimental support for the clinical application of this drug in the targeted therapy on the inflamed cartilage.

Nonobstructive azoospermia (NOA), one of the most severe types of male infertility, etiology often remains unclear in most cases. Therefore, this study aimed to detect four biallelic detrimental variants (0.5%) in the minichromosome maintenance domain containing 2 ( MCMDC2 ) genes in 768 NOA patients by whole-exome sequencing (WES). Hematoxylin and eosin (H&E) demonstrated that MCMDC2 deleterious variants caused meiotic arrest in three patients (c.1360G>T, c.1956G>T, and c.685C>T) and hypospermatogenesis in one patient (c.94G>T), as further confirmed through immunofluorescence (IF) staining. The single-cell RNA sequencing data indicated that MCMDC2 was substantially expressed during spermatogenesis. The variants were confirmed as deleterious and responsible for patient infertility through bioinformatics and in vitro experimental analyses. The results revealed four MCMDC2 variants related to NOA, which contributes to the current perception of the function of MCMDC2 in male fertility and presents new perspectives on the genetic etiology of NOA.

The patient is a male neonate born at term. He was admitted 16 minutes after birth due to stridor and inspiratory respiratory distress. Physical examination revealed a cleft palate, and a grade II systolic ejection murmur was audible at the left sternal border. Whole exome sequencing identified a heterozygous variant in the SON gene, c.5753-5756del (p.Val1918GlufsTer87), which was absent in either parent, indicating a de novo mutation. According to the guidelines of the American College of Medical Genetics and Genomics, this was classified as a "pathogenic variant" leading to a diagnosis of Zhu-Tokita-Takenouchi-Kim (ZTTK) syndrome. Upon admission, symptomatic supportive treatment was provided. Follow-up at the age of 8 months revealed persistent stridor; the infant could only consume small amounts of milk and was unable to sit steadily. This patient represents the youngest reported case to date, and his symptoms expand the clinical spectrum of the disease, providing valuable insights for clinical diagnosis and treatment.

OBJECTIVE: This study aims to analyze the influence factors of lower urinary tract symptoms (LUTS) in patients receiving radical prostatectomy for prostate cancer, and to explore effective nursing strategy in order to provide a theoretical basis for improving the postoperative quality of life of patients. METHODS: A retrospective study was conducted on 103 elderly male patients who underwent radical prostatectomy for prostate cancer in the Department of Urology at General Hospital of Eastern Theater Command from August 2022 to August 2024. The patients were categorized into two groups based on whether LUTS occurred. Demographic and clinical characteristics, perioperative parameters, follow-up data, and participation in pelvic floor muscle training were analyzed to identify risk factors associated with postoperative LUTS. RESULTS: The incidence of postoperative LUTS in the patients with LUTS before the operation was significantly higher than that in the patients without LUTS before the operation (68.42% vs 32.61%, P=0.001). Additionally, the use of larger catheters (22F) was closely associated with an increased incidence of postoperative LUTS(P<0.01). Pelvic floor exercises demonstrated a significant protective effect, with patients who engaged in pelvic floor exercises exhibiting a lower incidence of postoperative LUTS (38.60% vs 60.87%, P=0.040). Regression analysis further revealed that pelvic floor exercises was the protective factor for postoperative LUTS (OR=0.215, 95%CI: 0.091－0.508, P<0.01). CONCLUSION Preoperative LUTS and catheter size are significant risk factors for the occurrence of postoperative LUTS following radical prostatectomy. Pelvic floor muscle exercise after surgery has a protective effect. Postoperative personalized nursing interventions are necessary for different patients to achieve optimal recovery outcomes.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disorder affecting multiple systems, characterized by the development of harmful autoantibodies and immune complexes that lead to damage in organs and tissues. Chinese medicine (CM) plays a role in mitigating complications, enhancing treatment effectiveness, and reducing toxicity of concurrent medications, and ensuring a safe pregnancy. However, CM mainly solves the disease comprehensively through multi-target and multi-channel regulation process, therefore, its treatment mechanism is often complicated, involving many molecular links. This review introduces the research progress of pathogenesis of SLE from the aspects of genetics, epigenetics, innate immunity and acquired immunity, and then discusses the molecular mechanism and target of single Chinese herbal medicine and prescription that are commonly used and effective in clinic to treat SLE.

ObjectiveTo develop a nomogram-based risk prediction model for chronic obstructive pulmonary disease (COPD) incidence among the community-dwelling population aged 40 years old and above, so as to provide targeted references for the screening and prevention of COPD. MethodsBased on a natural population cohort in suburban Shanghai, a total of 3 381 randomly selected participants aged ≥40 years underwent pulmonary function tests between July and October 2021. Cox stepwise regression analysis was used to develop overall and gender-specific risk prediction models, along with the construction of corresponding risk nomograms. Model predictive performance was evaluated using the C-indice, area under the curve (AUC) values, and Brier score. Stability was assessed through 10-fold cross-validation and sensitivity analysis. ResultsA total of 3 019 participants were included, with a median follow-up duration of 4.6 years. The COPD incidence density was 17.22 per 1 000 person-years, significantly higher in males (32.04/1 000 person-years) than that in females (7.38/1 000 person-years) (P<0.001). The overall risk prediction model included the variables such as gender, age, education level, BMI, smoking, passive smoking, and respiratory comorbidities. The male-specific model incorporated the variables such as age, BMI, respiratory comorbidities, and smoking, while the female-specific model included age, marital status, respiratory comorbidities, and pulmonary tuberculosis history. The C-indices for the overall, male-specific, and female-specific models were 0.829, 0.749, and 0.807, respectively. The 5-year AUC values were 0.785, 0.658, and 0.811, with Brier scores of 0.103, 0.176, and 0.059, respectively. Both 10-fold cross-validated C-indices and sensitivity analysis (excluding participants with a follow-up duration of <6 months) yielded C-indices were above 0.740. ConclusionThis study developed concise and practical overall and gender-specific COPD risk prediction models and corresponding nomograms. The models demonstrated robust performance in predicting COPD incidence, providing a valuable reference for identifying high-risk populations and formulating targeted screening and personalized management strategies.

This study aims to integrate data mining techniques of single cell transcriptomics and spatial transcriptomics, along with animal experiment validation, so as to systematically characterize the protective effects of Jianpi Tongluo Formula(JTF) on the cartilage in knee osteoarthritis(KOA) and elucidate the underlying molecular mechanisms. Single cell transcriptomics and spatial transcriptomics datasets(GSE254844 and GSE255460) of the cartilage tissue obtained from KOA patients were analyzed to map the single cell-spatial heterogeneity and identify key pathogenic factors. After that, a KOA rat model was established via knee joint injection of papain. The intervention effects of JTF on the expression features of these key factors were assessed through real-time quantitative polymerase chain reaction(PCR), Western blot, and immunohistochemical staining. As a result, the integrated single cell and spatial transcriptomics data identified distinct cell subsets with different pathological changes in different regions of the inflamed cartilage tissue in KOA, and their differentiation trajectories were closely related to the inflammatory fibrosis-like pathological changes of chondrocytes. Accordingly, the expression levels of the two key effect targets, namely nuclear receptor coactivator 4(NCOA4) and high mobility group box 1(HMGB1) were significantly reduced in the articular surface and superficial zone of the inflamed joints when JTF effectively alleviated various pathological changes in KOA rats, thus reversing the abnormal chondrocyte autophagy level, relieving the inflammatory responses and fibrosis-like pathological changes, and promoting the repair of chondrocyte function. Collectively, this study revealed the heterogeneous characteristics and dynamic changes of inflamed cartilage tissue in different regions and different cell subsets in KOA patients. It is worth noting that NCOA4 and HMGB1 were crucial in regulating chondrocyte autophagy and inflammatory reaction, while JTF could reverse the regulation of NCOA4 and HMGB1 and correct the abnormal molecular signal axis in the target cells of the inflamed joints. The research can provide a new research idea and scientific basis for developing a personalized therapeutic schedule targeting the spatiotemporal heterogeneity characteristics of KOA.

Hepatocellular carcinoma (HCC) expresses abundant glycolytic enzymes and displays comprehensive glucose metabolism reprogramming. Aldolase A (ALDOA) plays a prominent role in glycolysis; however, little is known about its role in HCC development. In the present study, we aim to explore how ALDOA is involved in HCC proliferation. HCC proliferation was markedly suppressed both in vitro and in vivo following ALDOA knockout, which is consistent with ALDOA overexpression encouraging HCC proliferation. Mechanistically, ALDOA knockout partially limits the glycolytic flux in HCC cells. Meanwhile, ALDOA translocated to nuclei and directly interacted with c-Jun to facilitate its Thr93 phosphorylation by P21-activated protein kinase; ALDOA knockout markedly diminished c-Jun Thr93 phosphorylation and then dampened c-Jun transcription function. A crucial site Y364 mutation in ALDOA disrupted its interaction with c-Jun, and Y364S ALDOA expression failed to rescue cell proliferation in ALDOA deletion cells. In HCC patients, the expression level of ALDOA was correlated with the phosphorylation level of c-Jun (Thr93) and poor prognosis. Remarkably, hepatic ALDOA was significantly upregulated in the promotion and progression stages of diethylnitrosamine-induced HCC models, and the knockdown of A ldoa strikingly decreased HCC development in vivo. Our study demonstrated that ALDOA is a vital driver for HCC development by activating c-Jun-mediated oncogene transcription, opening additional avenues for anti-cancer therapies.
