BACKGROUND: The benefits of ideal cardiovascular-health metrics (ICVHMs) in patients with renal insufficiency remain unclear. This study aimed to investigate the associations between ICVHM and prognosis in a renal insufficiency population. METHODS: The trial enrolled 29,682 participants from the US National Health and Nutrition Examination Survey (NHANES), 2007-2018, with mortality follow-up through December 31, 2019. Participants were divided into three groups based on estimated glomerular filtration rates. Cardiovascular health was assessed using new "Life's Essential 8" metrics. Cox regression analyses based on NHANES data were used to determine the associations between ICVHMs and cardiovascular mortality in patients with renal insufficiency. RESULTS: During a mean follow-up of 6.58 years, ideal cardiovascular health (hazard ratio [HR] = 0.42; 95% confidence interval [CI]; 0.25-0.70) and ideal health behavior (HR = 0.53; 95% CI; 0.39-0.73) reduced cardiovascular mortality in participants with renal insufficiency. For each one ICVHM increment, a 25% reduction in cardiovascular mortality was recorded (95% CI; 0.69-0.82). When compared with participants with normal renal function, for those with mild renal insufficiency, the HR for cardiovascular mortality gradually decreased from 1.47 (95% CI; 0.85-2.52) in those who had ≤1 ICVHMs to 0.30 (95% CI; 0.12-0.77) in participants who had >6 ICVHMs. CONCLUSIONS From an ICVHM perspective, enhanced cardiovascular benefits were observed in individuals with renal insufficiency, coupled with a reduced risk of all-cause mortality. Furthermore, when compared with individuals with normal renal function, increased ICVHMs can mitigate adverse risks associated with renal impairment.

Objective:To investigate the functional connectivity of default mode network (DMN) and limbic system, the expression level of inflammatory cytokine and their correlation in bipolar disorder type Ⅱ(BDⅡ) patients with depressive episodes.Methods:Thirty-three BD Ⅱ patients with depressive episodes and forty-six healthy controls were recruited to complete the resting-state functional magnetic resonance imaging (rs-fMRI). After image preprocessing, the DMN and limbic system were extracted from the image data by independent component analysis (ICA), so as to compare the differences of functional connectivity of resting brain network between the patients and the controls.Serum levels of inflammatory cytokines interleukin-6 (IL-6), interleukin-8(IL-8), interleukin-10(IL-10), tumor necrosis factor-α (TNF-α), and C-C motif chemokine ligand 4 (CCL4) in patients and healthy controls were detected.The correlation between functional connectivity of different brain regions and inflammatory cytokines was analyzed.SPSS 17.0 software was used for data statistical analysis.The two samples were compared using t-test or Mann-Whitney U-test, and Spearman was used for correlation testing. Results:In BDⅡ patients, the functional connectivity of the right medial prefrontal cortex(cluster-size=7 voxel, cluster-level PGRF<0.05, MNI: x=6, y=54, z=9, t=-3.765) and the left superior frontal gyrus(cluster-size=10 voxel, cluster-level PGRF<0.05, MNI: x=-21, y=54, z=15, t=-4.139) in DMN decreased, while the left cerebellum Ⅳ and Ⅴ lobules of limbic system (cluster-size=21 voxel, cluster-level PGRF<0.05, MNI: x=-15, y=-24, z=-30, t=4.468) and cerebellar tonsil of left cerebellum posterior lobe(cluster-size=8 voxel, cluster-level PGRF<0.05, MNI: x=-15, y=-51, z=-45, t=4.138) in the limbic system increased.Compared with the healthy controls, the serum levels of IL-10(7.39 (6.33, 9.32) pg/mL vs 6.54 (5.84, 7.39) pg/mL, Z=-2.937, P=0.003)and CCL4 (39.31 (25.77, 68.70) pg/mL vs 31.30 (20.32, 40.89) pg/mL, Z=-2.209, P=0.027) were higher in BDⅡ patients.The functional connectivity of the left cerebellum Ⅳ and Ⅴ lobules was positively correlated with the serum levels of IL-10 ( r=0.432, P=0.031) and that of the cerebellar tonsil of left cerebellum posterior lobe was positively correlated with the serum levels of IL-10 ( r=0.429, P=0.032) and CCL4 ( r=0.402, P=0.046). Conclusion:The functional connectivity of DMN and limbic system in BDⅡ patients with depressive episode is abnormal in resting-state fMRI.The expression level of inflammatory cytokines in patients' serum increases, and has correlation with the functional connection of limbic system.

Polyetheretherketone (PEEK) as a new type of thermoplastic engineering plastic, has good biological activity, elastic modulus close to human cortical bone and radiation permeability, and has been widely used in medical field. This study aims to explore the safety and clinical efficacy of using 3D printing personalized PEEK materials to repaire scapular bone defects after bone tumor resection. A total of 6 patients who underwent the implantation of 3D printed PEEK scapular prosthesis from January 2020 to December 2021 in Yunnan Cancer Hospital were retrospectively analyzed. There were 3 males and 3 females, with age ranged from 14 to 52 years. There were 1 case of synovial sarcoma, 1 of Ewing's sarcoma, and 4 of chondrosarcoma. PEEK prosthesis was designed and fabricated based on CT data before surgery. Tumor resection and prosthesis replacement were performed under the premise of ensuring safe surgical boundaries, including 2 cases of total scapular prosthesis replacement and 4 cases of partial scapular prosthesis replacement. The operation time was 90-170 min, and the intraoperative blood loss was 100-400 ml. All 6 patients received satisfactory follow-up, with a tumor progression free survival time of 16-28 months. No tumor recurrence or metastasis was observed, and all patients survived tumor free. At last follow-up, the Constant-Murley shoulder joint score was a minimum of 62 points and a maximum of 68 points. The Japanese Orthopaedic Association's shoulder joint score was 63 points minimum and 78 points maximum. Computer-aided design 3D printing PEEK material prosthesis has certain advantages in the treatment of scapular tumor limb salvage. It has light weight, well adapted, relatively simple installation, good histocompatibility, and can obtain a better appearance and function of the shoulder joint after operation. It can become one of the options for limb salvage treatment of scapular tumor.

To evaluate the clinical effects and pathological characteristics of gastric tumors of fundic gland type treated with endoscopic submucosal dissection (ESD), data of 7 patients who treated by ESD and whose postoperative pathology indicated gastric adenocarcinoma of fundic gland type or gastric oxyntic gland adenoma in Endoscopic Center of Beijing Chao-Yang Hospital of Capital Medical University from August 2018 to June 2022 were collected. The clinical characteristics, surgical complications, preoperative and postoperative pathological data and follow-up data were evaluated. The lesions of the 7 patients were all located at gastric fundus, and were treated by ESD successfully. No bleeding, perforation or other complications occurred during and after the operation. Postoperative pathology showed that tumor cells originated from deep mucosa with an invasive growth pattern. Most of tumor surfaces were covered with normal concave epithelium. Tumors infiltrated into submucosa in 4 patients, and submucosa infiltration depth was more than 500 μm (550 μm) in 1 patient. Immunohistochemistry showed that MUC-6 was diffusely positive, indicating that the tumor originated from the main cell source. The expressions of MUC-2, MUC-5AC, CDX-2, CD10, and CgA were negative in all cases. With the mean follow-up time of 21 months, the ulcer healed well after the operation, with no recurrence. Gastric tumors of fundic gland type have relatively unique biological characteristics, and ESD is the preferred treatment. In addition, the histological characteristics can be used to differentiate from other gastric tumors by immunohistochemistry.

Objective    To analyze the expression of cold-induced RNA-binding protein (CIRBP) in lung adenocarcinoma and its clinical significance based on bioinformatics, in order to provide a new direction for the study of therapeutic targets for lung adenocarcinoma. Methods    The CIRBP gene expression data and patient clinical information data in lung adenocarcinoma tissues and adjacent tissues were downloaded from The Cancer Genome Atlas and Gene Expression Omnibus databases. The expression of CIRBP in lung adenocarcinoma was analyzed. Furthermore, its relationship with clinicopathological features and prognosis in patients with lung adenocarcinoma was analyzed. GO and KEGG enrichment analysis were carried out for the screened genes. The CIRBP protein interaction network was constructed by STRING, and the correlation analysis was carried out using the GEPIA online website. Results    The expression level of CIRBP gene in lung adenocarcinoma tissues was significantly lower than that in adjacent tissues (P<0.01), and its expression level was correlated with T stage and N stage in clinicopathological features. The prognosis of patients with high CIRBP expression in lung adenocarcinoma was significantly better than that with low CIRBP expression. Univariate and multivariate Cox regression analysis showed that CIRBP was an independent prognostic factor in patients with lung adenocarcinoma. GO functional annotation showed its enrichment in organelle fission, nuclear fission, chromosome separation, and DNA replication, etc. KEGG analysis showed that it was mainly involved in cell cycle and DNA replication. Protein interaction network and GEPIA online analysis showed that the expression level of CIRBP  was negatively correlated with the expression level of cyclin B2. Conclusion    CIRBP gene is down-regulated in lung adenocarcinoma tissues, and its expression level is closely related to patient prognosis. CIRBP gene may be a potential therapeutic target and prognostic marker for lung adenocarcinoma.
