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 clinical efficacy of oral microscope-assisted microflap periodontal bone grafting in treating class Ⅱ furcation involvement in mandibular molars, and to provide clinical evidence for its treatment in furcation involvement. Methods: This study was reviewed and approved by the institutional ethics committee, and informed consent was obtained from all patients. Sixty mandibular molars with class II furcation involvement caused by periodontitis were enrolled in a randomized controlled clinical study, utilizing a random number table method. Patients were categorized into a control group (n=30) and an experimental group (n=30) based on the surgical procedure employed. The control group underwent periodontal flap surgery with an internal oblique incision and vertical incision; this procedure was performed without the aid of a microscope. Conversely, the experimental group underwent micro flap periodontal bone grafting surgery without vertical incision; an oral microscope was used for this procedure. Both groups were analyzed 6 months after surgery, and postoperative gingival recession (GR), probing depth (PD), bleeding index (BI), vertical bone height increase (VBHI), pain level, and complications were recorded. Results: Both groups showed improvement in PD and BI after 6 months compared to preoperative levels: the control group had a preoperative PD of (7.33 ± 1.72 mm) and a 6-month postoperative PD of (3.37 ± 0.96 mm), with statistically significant differences (P<0.001). The preoperative PD of the experimental group was (7.27 ± 1.57 mm), and the 6-month postoperative PD was (3.00 ± 0.69 mm), with statistically significant differences (P<0.001). The BI of the control group decreased from 3.03 ± 1.03 before surgery to 0.77 ± 0.82 at 6 months after surgery (P<0.001), while the BI of the experimental group decreased from 3.20 ± 1.09 before surgery to 0.73 ± 0.64 at 6 months after surgery (P<0.001), and the differences were statistically significant. The experimental group showed a significant improvement in GR (0.70 ± 0.59 mm) compared to preoperative GR (1.26 ± 0.94 mm) at 6 months after surgery (P=0.007), while the control group showed an increase in GR (1.37 ± 0.89 mm) at 6 months after surgery compared to preoperative GR (1.13 ± 0.97 mm), but the difference was not statistically significant (P=0.337). The inter group comparison results showed that there were no statistically significant differences in PD and BI between the two groups at 6 months after surgery (PD: P=0.096, BI: P=0.861); The GR of the experimental group was lower than that of the control group, and the difference was statistically significant (P=0.001). There was no statistically significant difference in postoperative VBHI between the two groups (P=0.128). The pain level scores of the experimental group were lower than those of the control group at 4 and 24 hours after surgery (P<0.001). None of the patients experienced complications. Conclusion Microflap periodontal bone grafting assisted by an oral microscope effectively improves the periodontal condition of patients with grade Ⅱ root bifurcation lesions of mandibular molars, and the bone grafting effect is good, with mild pain and good safety.

OBJECTIVE: To explore the effect mechanism of electroacupuncture (EA) for ameliorating diabetic peripheral neuropathy (DPN) based on the analysis of gut microbiota and metabolomics. METHODS: Thirty SPF-grade male SD rats were randomly divided into a normal group, a model group, and an EA group, with 10 rats in each one. Except in the normal group, the intraperitoneally injection with streptozotocin was used to induce diabetes mellitus model in the rest groups. In the EA group, acupuncture was delivered at bilateral "Zusanli" (ST36), "Sanyinjiao" (SP6), "Pishu" (BL20) and "Shenshu" (BL23), and electric stimulation was attached to "Zusanli" (ST36)-"Sanyinjiao" (SP6) and "Pishu" (BL20)-"Shenshu" (BL23), on the same side, with continuous wave and a frequency of 2 Hz, for 10 min in each intervention. The intervention measure of each group was delivered once every 2 days, 3 times a week, for 8 consecutive weeks. Body weight, random blood glucose (RBG), thermal withdrawal latency (TWL), and mechanical withdrawal threshold (MWT) before intervention, and in 4 and 8 weeks of intervention, separately, as well as sensory nerve conduction velocity (SCV) and motor nerve conduction velocity (MCV) of the sciatic nerve after intervention were measured. Metagenomic sequencing (MS) was used to analyze gut microbiota and screen for differential species. Liquid chromatography-mass spectrometry (LC-MS) was employed to detect the differential metabolites in plasma, and the metabolic pathway enrichment analysis was performed on the differential metabolites. Spearman correlation analysis was adopted to assess the relationship between gut microbiota and metabolomics. RESULTS: After 4 and 8 weeks of intervention, when compared with the model group, the EA group showed the increase in body weight, TWL, MWT (P<0.01), and the decrease in RBG (P<0.01). Compared with the normal group, SCV and MCV, as well as Chao1 index were dropped in the model group (P<0.01), and those were elevated in the EA group when compared with those in the model group (P<0.01). The dominant bacterial phyla of each group were Firmicutes (F) and Bacteroidota (B), the ratio of them (F/B) in the model group was lower than that of the normal group (P<0.05), and F/B in the EA group was higher when compared with that in the model group (P<0.05). In comparison with the normal group, the relative abundance increased in Prevotella, Segatella, Prevotella-hominis and Segatella-copri (P<0.05); and it decreased in Ligilactobacillus, Eubacterium, Pseudoflavonifractor, Ligilactobacillus-murinus (P<0.05) in the model group. Compared with the model group, the relevant abundance of the above mentioned gut bacteria was all ameliorated in the EA group (P<0.05, P<0.01). Among the three groups, 120 differential metabolites were identified and enriched in 28 key metabolic pathways, such as glycerophospholipid and linoleic acid, of which, glycerophospholipid was the most significantly affected pathway in EA intervention. Spearman correlation analysis showed that 6 phosphatidylcholine metabolites were significantly positively correlated with Pseudoflavonifractor and were negatively with Prevotella, Segatella, Prevotella-hominis, Segatella-copri; 5 phosphatidylethanolamine metabolites were significantly negatively correlated with Pseudoflavonifractor and positively correlated with Prevotella, Segatella, Prevotella-hominis, Segatella-copri. CONCLUSION EA may regulate metabolic pathways such as glycerophospholipid, modulate specific gut microbiota such as Pseudoflavonifractor, Prevotella, and Segatella, and the co-expressed differential metabolites like phosphatidylcholine and phosphatidylethanolamine, thereby reducing blood glucose and protecting nerve function, so as to relieve the symptoms of DPN of rats.

Alzheimer′s disease is a serious neurodegenerative disorder. Approximately 80% to 90% of patients are accompanied by behavioral and psychological symptoms of dementia (BPSD), which manifest as a series of behavioral, psychological and mental abnormalities. These abnormalities can accelerate the cognitive deterioration and premature death of patients, and thus are regarded as important clinical symptoms. However, the pathogenesis of BPSD is still unknown, and treatment methods are limited. The pathogenesis of BPSD from the perspective of neuroimaging and pathophysiology, and possible treatment measures were analyzed in this article, in order to provide references for the early diagnosis and treatment of BPSD.

Objective:To investigate the attention level of oral medicine residents in standardized training (referred to as residency training) to oral aesthetic information and its influencing factors.Methods:This study was a cross-sectional study, which included 262 residents undergoing standardized training at Hospital of Stomatology, Wuhan University in January 2020. Among them, there were 73 males and 189 females, with an age range of 23-33 (26±2) years. A questionnaire survey method was used, and the questionnaire included the basic characteristics of the subjects (gender, grade, major, identity, and having training experience in prosthodontic base or not) as well as their attention to oral aesthetic information (facial proportions, facial midline, smile line, facial contour, E-line, nasolabial angle, tooth shape and contour, and tooth proportions). Differences in the attention to oral aesthetic information among residents with different basic characteristics were compared, and a multivariable logistic regression was used to identify the influencing factors.Results:Among the 262 oral medicine residents, 256 (97.7%) believed that it was necessary to pay attention to oral aesthetic information. The differences in attention to facial proportions between residents of different genders and between those with and without training experience in the prosthodontic base were statistically significant (both P<0.05). The results of the multivariate logistic regression showed that male residents were less likely to pay attention to facial proportions compared with female residents ( OR=0.45, 95% CI: 0.23-0.88). Compared with residents specializing in orthodontics, non-orthodontic residents were less likely to pay attention to the E-line ( OR=0.14-0.27, 95% CI: 0.04-0.68) and nasolabial angle ( OR=0.14-0.31, 95% CI: 0.04-0.81). Residents who were graduate students with integrated four certificates were more likely to pay attention to the E-line compared with industry-based personnel ( OR=1.88, 95% CI: 1.01-3.49). Residents without training experience in the prosthodontic base were less likely to pay attention to the facial proportion ( OR=0.44, 95% CI: 0.20-0.97) and tooth shape and contour ( OR=0.33, 95% CI: 0.11-0.98) compared with those with such training experience in prosthodontic base. Conclusions:Oral medicine residents have a high level of attention to oral aesthetic information. Gender, major, identity, and having training experience in the prosthodontic base or not are factors that influence their attention to oral aesthetic information.

The study was a prospective observational study. A total of 24 patients who underwent maintenance hemodialysis (MHD) at Haidian Hospital in Beijing from May 2024 to June 2024 were included as the study subjects. The safety and efficacy of a new single-needle dialysis in MHD patients were evaluated. The reasons for using single-needle dialysis included waiting for the maturity of internal fistula(7 cases, 29.17%), autogenous arteriovenous fistula thrombosis occurred (6 cases, 25.00%), puncture difficulty occurred (7 cases, 29.17%), and pain sensitivity or elderly (4 cases, 16.67%). The results showed that the average blood flow was (155.65±5.90) ml/min, total blood volume was (35.92±2.65) L during single-needle dialysis. One patient had slight puncture leakage, and the puncture success rate was 95.83%. Relevant indicators of dialysis adequacy showed that the average urea clearance (Kt/V) was 0.90±0.42, urea reduction ratio was 58.31%±7.93%, and online real-time Kt/V monitoring average value was 0.98±0.55. The results suggest that the application of the new improved single-needle dialysis mode in MHD patients is safe and effective.

To further investigate the molecular genetic characteristics of enzomatic nasal tumor vi-rus of goats(ENTV-2)in Yunnan Province,this study measured and analyzed the entire genome of ENTV-2 in Yunnan Province.The results showed that the complete genome sequence of the EN-TV-2 YN2023 strain(GenBank accession number:PP682590.1)was successfully obtained.The YN2023 strain has a total length of 7 307 bp and a typical structure of 5'-M5-gag-pro-pol-env-M3-3'.Whole genome sequence homology analysis showed that the nucleotide homology between YN2023 strain and 41 reference strains ranges from 85.3％to 95.5％.The whole genome evolution-ary tree indicates that the YN2023 strain is closely related to the prevalent strains in China,with certain genetic diversity and geographical clustering.The analysis of the gag gene evolutionary tree shows that the gag gene cluster of YN2023 strain is on a branch of the ENTV-2 gag gene,and YN2023 is clustered on the same small branch as enENTV-FJ1 and GDQY2017 strains,with the closest genetic relationship.The env gene evolutionary tree shows that YN2023 is on the same branch as GDQY2017,GDZJ2022,ENTV-2CHN1-6,ENTV-FJ1,and ENTV-FJ3,and is also on the same branch as GDQY2017,indicating a close genetic relationship.Recombination analysis showed that the YN2023 strain underwent a potential recombination event between breakpoint positions 6378-7478 bp,with the Chinese Chongqing strain enENTV-CQ1(OR669623.1)as the primary parent and the Chinese Sichuan strain BH(MT254062.1)as the secondary parent.This study enriches the genomic information of the ENTV-2 strain in Yunnan Province and provides data sup-port for the genetic variation of ENTV-2 in Yunnan Province.

ObjectiveTo explore the regulatory effects and mechanisms of Astragali Radix polysaccharide （APS） on inhibitor of differentiation1 （ID1） and protein kinase B （Akt） in gastric cancer. MethodsImmunohistochemical staining was used to detect the expression of ID1 and Akt in 61 gastric cancer tissue samples and 20 adjacent normal gastric tissue samples. Immunofluorescence was used to detect the localization of ID1 and Akt. The effects of APS at the concentrations of 0.625， 1.25， 2.5， 5， 10， 20 mg·L^-1 on the proliferation of gastric cancer MGC-803 cells were examined by the cell counting kit-8（CCK-8） method and the colony formation assay. The target information of APS was retrieved from the Traditional Chinese Medicine Systems Pharmacology and Analysis Platform and Swiss Target Prediction. Keywords such as gastric cancer， gastric tumor， and stomach cancer were searched against GeneCards， UniProt， DisGeNET， and Online Mendelian Inheritance in Man （OMIM） for the screening of gastric cancer-related targets. The online tool jvenn was used to create the Venn diagram to identify the common targets， and STRING and Cytoscape were used to construct the protein-protein interaction network. Gene Ontology （GO） and Kyoto Encyclopedia of Genes and Genomes （KEGG） pathway enrichment analyses were conducted via R 4.2.2 to predict the potential roles of APS in the development of gastric cancer. The cell scratch assay was employed to assess the effect of APS on the migration of MGC-803 cells. The protein and mRNA levels of ID1 and Akt in the cells treated with APS were determined by Western blot and Real-time PCR， respectively. ResultsCompared with the adjacent normal gastric tissue， the gastric adenocarcinoma tissue showed increased positive expression of ID1 （χ² =81.00， P<0.01）. Immunofluorescence detection showed that ID1 and Akt were mainly located in the cytoplasm of gastric adenocarcinoma cells. Bioinformatics analysis identified 14 common genes shared between APS and gastric cancer. The average degree of protein-protein interaction network nodes was 14.29. GO and KEGG pathway enrichment results showed that ID1 and Akt were significantly enriched in the Rap1 and phosphatidylinositol-3-kinase （PI3K） /Akt signaling pathways. Cell experiments demonstrated that 5-fluorouracil （0.1 mg·L^-1） and APS （10， 20 mg·L^-1） groups showed decreased cell proliferation， migration， and colony formation. Compared with the control group， 10， 20 mg·L^-1 APS inhibited the proliferation of MGC-803 cells （P<0.01）， with 10 mg·L^-1 APS demonstrating stronger inhibitory effect. In addition， APS at 10， 20 mg·L^-1 inhibited the migration （P<0.01） and colony formation （P<0.05， P<0.01） of MGC-803 cells. Compared with the control group， APS at 10， 20 mg·L^-1 down-regulated the protein levels of ID1 （P<0.01） and Akt （P<0.05） and the mRNA levels of ID1 （P<0.05， P<0.01） and Akt （P<0.05， P<0.01） in MGC-803 cells. ConclusionID1 and Akt are highly expressed in the gastric adenocarcinoma tissue， which may be related to the development of gastric cancer. APS can down-regulate the protein and mRNA levels of ID1 and Akt to exert anti-tumor effects， which is expected to provide new therapeutic targets for gastric cancer treatment.

Objective To establish a rat model of Alzheimer's disease (AD) expressing human triple mutant amyloid precursor protein (APP) in the hippocampus, and to provide a model for the study of disease mechanisms and drug development. Methods Twenty-four 12-week-old SPF-grade female SD rats were randomly divided into a blank control group, a virus control group and an experimental group, with eight rats in each group; among them, the experimental group received a stereotaxic injection of adeno-associated virus (AAV) carrying the human triple mutant APP and NanoLuc luciferase genes into the hippocampus. In vivo imaging was used to observe viral expression in the brains of rats in each group, the novel object recognition test was used to assess the recognition memory of the rats in each group, real-time fluorescent quantitative PCR was used to detect the expression level of the APP gene, HE staining was used to examine the brain histopathology, Nissl staining was used to assess the hippocampal lesions, and immunohistochemistry was used to detect the deposition of amyloid β-protein (Aβ). Results In vivo imaging showed that reporter fluorescence was detected in the brains of rats in both experimental and virus control groups. Fluorescence quantitative PCR showed that the expression level of the APP gene was significantly increased in the brains of rats in the experimental group (P<0.01). Novel object recognition test revealed that the recognition memory of rats in the experimental group was significantly reduced compared with that of the blank control group (P<0.01). Six months after recombinant AAV virus infection, HE staining and Nissl staining of brain tissues showed that the number of neurons and Nissl bodies in the CA1 region of the hippocampus in the experimental group was reduced and disorganized; immuno-histochemistry testing of the CA1 region of the hippocampus and the pyramidal cell layer of the experimental group revealed prominent brown deposits, indicating Aβ protein deposition. Conclusion The rat model successfully established by stereotaxic injection and AAV-mediated delivery of human triple mutant APP gene exhibits typical AD features, providing a valuable animal model for studying AD pathology and developing drug therapies targeting Aβ protein deposition.
