Objective To identify renal function and other readily accessible indicators influencing the prognosis of renal cell carcinoma (RCC) patients after nephrectomy, and to construct a prognostic prediction model based on them. Methods The clinical and pathological data of 624 RCC patients undergoing radical or partial nephrectomy in the First Hospital of Shanxi Medical University during Jan. 2013 and Dec. 2021 were retrospectively analyzed. The independent prognostic factors affecting postoperative overall survival (OS) were identified with LASSO algorithm combined with Cox regression analysis. Based on these factors, a nomogram was constructed to predict the 1-, 3-, and 5-year survival rates. The performance of the model was evaluated using the concordance index (C-index), time-dependent receiver operating characteristic (ROC) curves and the area under the curve (AUC), calibration plots, and decision curve analysis (DCA). Finally, the cutoff value of the nomogram was calculated to stratify patients into risk groups. Kaplan-Meier survival analysis with log-rank testing was performed to compare outcomes between the risk groups. Results Nine independent prognostic factors were identified, including age, smoking history, diabetes mellitus history, maximum tumor diameter, tumor subtype, N stage, Fuhrman grade, preoperative serum creatinine and cystatin C (P＜0.05). The nomogram achieved a C-index of 0.891, with time-dependent AUC of 0.920, 0.903, and 0.867 for 1-, 3-, and 5-year OS, respectively. Calibration curves showed excellent agreement with actual observations, and DCA demonstrated significant clinical net benefits across a wide threshold probability range. Using a cutoff score of 110.4, Kaplan-Meier analysis revealed statistically significant survival differences between risk groups (P＜0.001). Conclusion The proposed nomogram, incorporating renal function and other readily accessible clinical indicators, exhibits strong predictive accuracy for postoperative survival in RCC patients and may serve as a practical tool for individualized clinical decision-making.

METHODS:A cross-sectional study was conducted enrolling myopic patients aged 18-50 y who underwent myopia screening from March 2023 to December 2023. Patients were stratified into three groups based on SE: the -3.00 D

ObjectiveTo investigate the anti-Alzheimer's disease （AD） effect of Dipsacus asper（DA） in the Caenorhabditis elegans model， and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α （PPARα）/transcription factor EB （TFEB） pathway. MethodsFirst， transgenic AD C. elegans individuals were assigned into the blank control， model， positive control （WY14643， 20 µmol·L^-1）， and low-， medium-， and high-dose （100， 200， and 400 mg·L^-1， respectively） DA groups. The amyloid β-42 （Aβ₄₂） formation in the muscle cells， the paralysis time， and the deposition of amyloid β-protein （Aβ） in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ， LC3I， LAMP2， and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα， and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB， Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain （LBD）. ResultsCompared with the model group， the positive control group and 200 and 400 mg·L^-1 DA groups showed prolonged paralysis time （P<0.05）， and all the treatment groups showed decreased Aβ deposition in the head （P<0.01）. DA within the concentration range of 50-500 mg·L^-1 did not affect the viability of BV2 cells. In addition， DA enhanced the autophagy flux （P<0.05）， up-regulated the mRNA levels of beclin1， Atg5， LAMP2， and CLN2 （P<0.05， P<0.01）， promoted the nuclear translocation of TFEB （P<0.05）， increased LAMP2 expression and autophagy flux （P<0.05， P<0.01）， and enhanced the transcriptional activities of PPARα and TFEB （P<0.01）. The positive control group and 200 and 400 mg·L^-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus （P<0.01）. UPLC-MS detected nine known compounds of DA， from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

Objective:To investigate the characteristics of cell subsets in rheumatoid arthritis patients complicated with interstitial lung disease (RA-ILD).Methods:The clinical data of 344 patients with RA admitted to the Affiliated Hospital of Nantong University from June 2022 to November 2023 were analyzed. The patients were categorized into two groups based on the diagnostic criteria of ILD: 120 cases in the RA associated with ILD group (RA-ILD group) were included and 224 cases in the RA without ILD group (RA group), the clinical characteristics were compared between the RA-ILD group and the RA group. The influence factors of RA-ILD were analyzed by univariate and multivariate logistic regression.Results:Compared with RA patients, RA-ILD patients were more common in males, with older age, longer course of disease, and higher smoking rate ( P<0.05). The high titer anti-cyclic citrullinated peptide (CCP) antibody, white blood cells, neutrophil, neutrophil to lymphocyte count ratio, aspartate aminotr-ansferase(AST), creatinine (Cr) and lactate dehydrogenase (LDH) levels in RA-ILD patients were higher than those in RA patients. The triglyceride level was lower than that of RA patients ( P<0.05). The percentage of total T cells in peripheral blood lymphocyte subsets in RA-ILD patients [68.65%(62.22%, 76.78%)] was lower than that in RA patients [71.88%(65.83%, 78.39%)] ( Z=-2.26, P=0.024). The percentage of CD4 +T cells [40.2% (32.10%, 45.23%)] was lower than that of RA patients [46.5% (39.74%, 53.19%)] ( Z=-6.29, P<0.001). CD4 +T cell count [486.50 (324.25, 636.75)cells/μl] was lower than that of RA patients [564.50 (438.25, 752.00)cells/μl] ( Z=-4.50, P<0.001). CD4 +/CD8 + levels [1.86 (1.26, 2.18)] were lower than those of RA patients [2.03 (1.40, 2.94)] ( Z=-2.79, P=0.005). B cell count [127.00 (78.00, 207.25)cells/μl] was lower than that of RA patients [163.50 (91.25, 231.50)cells/μl] ( Z=-2.11, P=0.035), The percentage of NK cells in peripheral blood lymphocyte subsets in RA-ILD patients [19.72%(13.14%, 25.83%)] was higher than that in RA patients [12.55% (8.23%, 17.80%)] ( Z=6.13, P<0.001). NK cell count [182.50 (109.00, 293.75)cells/μl] was higher than that of RA patients [156.00 (89.00, 194.75)cells/μl] ( Z=3.17, P=0.002). The percentage of CD8 +T cells [25.10 %(18.74%, 29.86%)] was higher than that of RA patients [22.27% (17.32%, 29.21%)] ( Z=2.00, P=0.046). Imaging types of RA-ILD patients showed that usual interstitial pneumonia (UIP) was more common, followed by non-specific interstitial pneumonia (NSIP). CD8 + T cell count and percentage expression level in UIP were higher than NSIP, and CD4 +/CD8 + expression level was lower than NSIP ( P<0.05). Multivariate logistic regression analysis of indicators with statistical differences were male gender [ OR(95% CI)=2.888 (1.556, 5.360), P=0.001], age [ OR(95% CI)=1.065 (1.033, 1.098), P<0.001], disease duration [ OR(95% CI)=1.004 (1.001, 1.007), P=0.013], high titer anti-CCP antibody [ OR(95% CI)=2.764 (1.214, 6.292), P=0.015], LDH [ OR(95% CI)=1.006 (1.002, 1.009), P=0.001], CD4 +T cell percentage [ OR(95% CI)=0.964 (0.929, 1.000), P=0.049], CD4 +T cell count [ OR(95% CI)=0.998 (0.996, 1.000), P=0.011] and NK cell count [ OR(95% CI)=1.004 (1.001, 1.007), P=0.003]. These indicators were correlated factors for RA-ILD. Conclusion:Male patients with older age, history of smoking and a long disease course are more likely to develop ILD. Male gender with older, long disease course, high titer anti-CCP antibody, increased LDH and NK cell count, CD4 +T cell percentage and decreased CD4 +T cell count are correlation factors for RA-ILD, which may help RA patients to recognize ILD early.

Objective:To analyze the genetic characteristics and evolutionary origin of hepatitis B virus (HBV) subgenotype D3 in China in 2020.Methods:Serum samples and demographic details from patients infected with HBV D3 subgenotype were collected. HBV genomic sequences were obtained by nested PCR amplification and subsequent sequencing. Phylogenetic analysis, nucleotide homology, amino acid mutation and evolution rate of the S protein were conducted by comparing with reference sequence using bioinformatics tools.Results:The complete HBV gene sequences of 14 samples of D3 subtype HBV were obtained. Compared with 97 reference sequences, it was found that the sequences with the highest homology were from India, Mongolia, Iran and China, with the homology ranging from 96.0% to 97.9%. Mutations of 24 amino acids were found in 14 strains of D3 subtype. Among them, T131A, Y134F and T140I were associated with immune escape-related mutations. The genetic diversity of HBV D3 subtype increased slowly before 1975, remained relatively constant from 1975 to 2000, and began to decline after 2000. Evolutionary rate analysis showed that samples QGLD D3-02 and 03 originated from a common ancestor with the Iranian reference strain in 1872, and the other 12 samples QGLD D3-04-17 originated from a common ancestor with the Mongolian reference strain in 1843.Conclusions:The gene sequence of HBV D3 subtype in China had the highest homology with reference sequences from India, Iran, Mongolia and China. Evolutionary rate analysis revealed that 14 cases of HBV D3 subtype originated from a common ancestor with reference strains from Mongolia and Iran, which enriched the sequence and evolution information of HBV D3 subtype and provided a reference basis for the molecular epidemiological study of HBV.

Objective:To investigate the drug resistance gene characteristics, plasmid characteristics and genome tracing of Shigella sonnei causing a bacillary dysentery outbreak in Shandong Province. Methods:Sixty-five Shigella sonnei strains isolated from a 2021 outbreak in a county of Shandong Province were analyzed using antimicrobial susceptibility testing, whole genome sequencing (WGS), characterization of resistance and virulence genes, plasmid profiling, core genome multilocus sequence typing (cgMLST), and single nucleotide polymorphism (SNP) analysis. Results:All isolates had the same resistance phenotype and genotypes and were multidrug-resistant ESBL-producing Shigella sonnei, carrying important virulence genes. Plasmid analysis revealed a conserved genetic arrangement, pil( M/ N/ O2/ P)-tra( F/ H/ J/ K/ N/ O/ P/ Q)-IS Ecp1- blaCTX-M-14-Tn 903- yub( J/ I/ F/ G/ E/ D), and shared across strains from diverse regions and bacterial species. The cgMLST and SNP analyses demonstrated concordant clustering, with all 65 outbreak-related strains forming a single cluster alongside human-derived strains from Guangxi. Conclusion:The ESBL-producing Shigella sonnei responsible for the outbreak shares a homologous relationship with Guangxi human-derived strains, and the detected resistance plasmids and virulence genes underscore the need to strengthen drug resistance surveillance and genome tracing.

Objective:To explore the design and application effect of a home-based pulmonary rehabilitation checklist for postoperative lung cancer patients and to analyze the feasibility of this innovative rehabilitation approach.Methods:A prospective non-concurrent controlled study was conducted. Eighty postoperative lung cancer patients from the Department of Thoracic Surgery, Henan Provincial People's Hospital, were conveniently selected. According to the time of admission, postoperative lung cancer patients from April to June 2024 ( n=40) were assigned to the control group, while those postoperative lung cancer patients from August to October 2024 ( n=40) were assigned to the experimental group. The control group was given routine home-based pulmonary rehabilitation knowledge education upon discharge, while the experimental group was provided with the application of a home-based pulmonary rehabilitation checklist in addition to the routine home-based pulmonary rehabilitation knowledge education. Assessments were performed on the day of discharge and 1-month post-discharge using the Chinese version-Strategies Used by People to Promote Health (C-SUPPH), the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC-QLQ-C30), the six-minute walk test (6MWT) and the Brog score. Results:A total of 40 patients in each group completed this study. Among them, there were 26 males and 14 females in the control group, aged (51.25 ± 11.39) years, and 23 males and 17 females in the experimental group, aged (53.07 ± 12.21) years. One month after discharge, the scores of positive attitude, self-decision making and self-stress reduction on the C-SUPPH in the experimental group were (44.25 ± 10.29), (30.76 ± 8.31) and (9.51 ± 2.17) points, respectively. They were higher than those in the control group (37.02 ± 7.14), (26.61 ± 6.71) and (7.58 ± 1.09) points, and the differences were statistically significant ( t=-3.65, -2.46, -5.03, all P<0.05). The scores of somatic function, role function, cognitive function and emotional function on the EORTC-QLQ-C30 in the experimental group were (65.77 ± 6.41), (71.46 ± 7.21), (70.11 ± 5.61) and (69.59 ± 5.71) points, respectively. They were higher than those in the control group (57.71 ± 7.01), (64.27 ± 5.25), (62.79 ± 7.18), (61.11 ± 6.25) points, and the differences were statistically significant ( t values were -6.34 to -5.08, all P<0.05). The 6MWT distance in the experimental group was (411.31 ± 35.02) m, which was higher than (376.58 ± 30.26) m in the control group, and the difference was statistically significant ( t=-4.75, P<0.05). The Brog score in the experimental group was (2.12 ± 0.68) points, which was lower than (2.50 ± 0.65) points in the control group, and the difference was statistically significant ( t=2.56, P<0.05). Conclusions:The implementation of home pulmonary rehabilitation list can improve the self-management ability of patients after lung cancer surgery, improve the quality of life, and then enhance the exercise ability, which is worthy of clinical promotion.

Objective:To analyze the symptoms,diagnosis and treatment of upper urinary tract calculi patients combined with mild and moderate benign prostatic hyperplasia(BPH)after ureteral stent implantation.Methods:One hundred and six BPH pa-tients who were hospitalized for upper urinary tract calculi and had ureteral stents retained from January 2019 to December 2022 were selected and divided into 2 weeks group and 4 weeks group according to the time of removal of ureteral stents after surgery.Their gener-al clinical data were analyzed and compared.International Prostatic Symptom Scale(IPSS),postoperative ureteral Stent Symptom Questionnaire(USSQ),and incidence of adverse events after ureteral stent removal were recorded before and after removal.Results:The scores of IPSS were significantly increased in all patients,and symptoms in urinary tract had improved significantly after discharge(P＜0.05).Compared with the 2 weeks group,the USSQ score of the 4 weeks group was significantly increased(P＜0.05).And no significant adverse event was observed in the 2 weeks group after the removal of ureteral sten.Conclusion:IPSS score and USSQ score increased significantly during stent implantation in BPH patients with lithiasis.And complications increased sig-nificantly over time.Following thorough clinical assessment,early ureteral stent removal demonstrates both safety and efficacy,repre-senting an optimal therapeutic approach in selected cases.

Objective:To analyze and summarize clinical phenotypic characteristics and genetic variations in patients with intellectual disability and pathogenic variations of the DYNC1H1 gene across 4 generations within a single family. Methods:Retrospective case analysis.Clinical data of a child with epilepsy and intellectual disability and her family members were collected from the Children′s Medical Center, Peking University First Hospital on December 2019.The child was followed up regularly.DNA was extracted from the peripheral blood of the child′s family members.Then whole-exome sequencing and Sanger sequencing were performed to identify the genetic variation type in the proband and her family members.The relationship between genotype and phenotype was further analyzed.Results:A total of 13 patients across 4 generations in the family had intellectual disability, and the proband also had drug-resistant epilepsy.The variation c. 13556C> A (p.A4519E) of the DYNC1H1 gene was confirmed by gene testing in 8 patients (no blood samples were obtained from the remaining patients). Conclusions:DYNC1H1 gene-related intellectual disability in most previously reported cases are caused by novel variations of this gene.In this study, a large family of 13 intellectual disability patients across 4 generations caused by a pathogenic mutation in the DYNC1H1 gene was summarized.The findings make precise genetic counseling possible for this family and provide a basis for further studies on the relationship between the genotype and phenotype of the DYNC1H1 gene.
