Objective To analyze the epidemiological characteristics and risk factors of chronic kidney disease in patients with 10 years of hypertension. Methods A total of 350 patients with 10 years or longer course of hypertension who underwent physical examination in the Second Affiliated Hospital of Air Force Medical University from June 2021 to June 2024 were selected. General information of the patients was collected through questionnaires. Renal function related indicators and imaging results were obtained through relevant laboratory tests and imaging examinations. Based on the results of renal function related indicators, the epidemiological characteristics of chronic kidney disease in hypertensive patients with 10 years of hypertension, as well as risk factors for chronic kidney disease in the hypertensive patients were identified. Results Among the 350 patients enrolled in this study, there were 71 (20.29%) with proteinuria, 32 (9.14%) with hematuria, and 40 (11.43%) with decreased renal function. A total of 80 (22.86%) cases with structural variations such as kidney stones and cysts were detected by renal B-mode ultrasound. There were 121 (34.57%) patients with hypertension and chronic kidney disease. There were statistically significant differences in gender, age, diabetes, hyperlipidemia and hyperuricemia between patients with chronic kidney disease and those without (P<0.05). Multivariate logistic regression analysis results showed that gender, age, diabetes, hyperlipidemia, and hyperuricemia were the risk factors for chronic kidney disease in patients with hypertension (P<0.05). Conclusion Patients with 10 years of hypertension have a high risk of chronic kidney disease, and the risk factors include gender, age, diabetes, hyperuricemia, and hyperlipidemia.

Xiaoaiping (XAP) Injection demonstrates the anti-prostate cancer (PCa) effects, yet the underlying mechanism remains unclear. This study aims to investigate the impact of XAP on PCa and elucidate its mechanism of action. PCa cell proliferation was evaluated using a cell counting kit-8 (CCK-8) assay. Cell apoptosis was assessed through Hoechst staining and Western blotting assays. Proteomics technology was employed to identify key molecules and significant signaling pathways modulated by XAP in PCa cells. To further validate potential key genes and important pathways, a series of assays were conducted, including acridine orange (AO) staining, transmission electron microscopy, and immunofluorescence assays. The molecular mechanism of XAP against PCa in vivo was examined using a PC3 xenograft mouse model. Results demonstrated that XAP significantly inhibited cell proliferation in multiple PCa cell lines. In C4-2 and prostate cancer cell line-3 (PC3) cells, XAP induced cellular apoptosis, evidenced by reduced B-cell lymphoma 2 (Bcl-2) levels and elevated Bcl-2-associated X (Bax) levels. Proteomic, immunofluorescence, and quantitative reverse transcription-polymerase chain reaction (qRT-PCR) investigations revealed a strong correlation between forkhead box O3a (FoxO3a) autophagic degradation and the anti-PCa action of XAP. XAP hindered autophagy by reducing the expression levels of autophagy-related protein 5 (Atg5)/autophagy-related protein 12 (Atg12) and enhancing FoxO3a expression and nuclear translocation. Furthermore, XAP exhibited potent anti-PCa action in PC3 xenograft mice and triggered FoxO3a nuclear translocation in tumor tissue. These findings suggest that XAP induces PCa apoptosis via inhibition of FoxO3a autophagic degradation, potentially offering a novel perspective on XAP injection as an effective anticancer therapy for PCa.

Objective:To explore the impact of multimorbidity on disability in older adults, providing a reference for formulating strategies for the management and nursing of multimorbidity and disability in older adults.Methods:Adopting the method of cross-sectional survey research, the data of 6 469 older adults (≥60 years old) were collected from the 2018 Chinese Longitudinal Healthy Longevity Survey database in July 2023, including basic information, chronic disease prevalence, and disability measured by basic activities of daily living (BADL), and instrumental activities of daily living (IADL). They were divided into multimorbidity and non-multimorbidity groups based on whether they had two or more chronic diseases. The propensity score matching (PSM) method was used to match the basic conditions of the two groups of older adults with the proportion of 1∶1. Binary logistic regression was applied to analyze the effects of multimorbidity on BADL disability and IADL disability.Results:Among 6 469 older adults, there were 2 882 males and 3 582 females, with 3 158 aged 60-84 years old and 3 311 aged over 84 years old. BADL disability accounted for 26.5% (1 712/6 469), while IADL disability accounted for 66.8% (4 324/6 469). There were 2 335 patients in the multimorbidity group and 4 134 patients in the non-multimorbidity group. Binary Logistic regression analysis showed that the risk of BADL disability in older adults in multimorbidity group was 1.511 times higher than that in the non-multimorbidity group (95% CI 1.317-1.734, P<0.01); the risk of IADL disability in older adults in the multimorbidity group was 1.618 times higher than that in the non-multimorbidity group (95% CI 1.426-1.835, P<0.01). Conclusions:Multimorbidity would increase the risk of disability in older adults. Relevant authorities should develop relevant interventions and nursing responses to enhance the prevention and management of multimorbidity and disability in older adults.

Objective:To evaluate the accuracy of ultrasound measurement of airway parameters in predicting difficult mask ventilation (DMV).Methods:Ninety-six patients, aged 18-90 yr, with body mass index of 16-39 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing elective endotracheal intubation under general anesthesia, were included in this study. Clinical airway evaluation was performed at 1 day before surgery, and modified Mallampati classification, thyromental distance and rating of the upper lip bite test were recorded. At 30 min before anesthesia induction, mandibular condylar motion, tongue longitudinal cross-sectional area and transverse diameter of tongue were measured by ultrasound, and the tongue volume (product of tongue longitudinal cross-sectional area and transverse diameter of tongue) was calculated. Mask ventilation was performed after induction of anesthesia, mask ventilation difficulty grade ≥Ⅲ was defined as DMV, the patients were divided into 2 groups according to whether DMV occurred: non-DMV group (NDMV group) and DMV group. Correlations between the clinical airway evaluation indexes and ultrasonic airway parameters with statistically significant differences between groups and DMV were assessed using Spearman′s rank correlation. The area under the receiver operating characteristics curve was used to evaluate the accuracy of each parameter in predicting DMV, the critical value was determined, and the accuracy, sensitivity, specificity, positive and negative predictive values were calculated. Results:The modified Mallampati classification, rating of the upper lip bite test, ultrasonic tongue longitudinal cross-sectional area, transverse diameter of tongue and tongue volume were positively correlated with DMV, and thyromental distance and mandibular condylar motion were negatively correlated with DMV ( P<0.05). The area under the receiver operating characteristics curve of mandibular condylar motion and tongue volume in predicting DMV were 0.898 and 0.862, respectively, the cut-off values were 1.19 cm and 99.94 cm 3, respectively, and the sensitivity and specificity were all over 70% and 90%, respectively, the positive predictive values were 92.31% and 88.46%, respectively. Conclusions:Ultrasonic measurements of mandibular condylar motion and tongue volume can accurately predict DMV.

In recent years, the etiology of periodontitis has tended to be based on the theory of flora imbalance. That is, periodontitis is not caused by specific bacteria but by the breakdown of the oral flora balance, which leads to an immune imbalance. Imbalanced bacterial flora cooperate with each other to produce virulent factors that destroy organism tissues and induce immune cells to produce abnormal levels of cytokines, causing greater damage. This article reviews the initiation of a flora imbalance, the interaction between bacteria, the immune damage of the host and the prevention and treatment of the flora imbalance. The literature review shows that peroxidase released by inflammatory reactions, host immune responses to pathogenic microorganisms and some systemic factors, such as diabetes, can trigger flora imbalance. As a result, ion transport, substance synthesis and metabolism of bacteria change; virulence factors increase; and the oral flora balance is disrupted. Red complex bacteria enter gingival epithelial cells, produce adhesin, and selectively inhibit the expression of specific chemokines, which is beneficial for other pathogenic bacteria to enter gingival epithelial cells. Toxicity factors increase throughout the body, directly destroying body tissues and inducing innate and adaptive immune responses, thus causing related immune damage. The dysbacteriosis model of periodontitis provides a new idea for the prevention and treatment of periodontitis, such as using biological factors, bacteriophages, probiotics and other methods to reduce the number of periodontal pathogens to restore the steady state of periodontal flora.
