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.

Objective To explore the mediating role of mindfulness between work immersion and professional well-being in clinical nurses. Methods A total of 477 clinical nurses were selected as the research subjects using the convenience sampling method. The levels of mindfulness, work immersion, and professional well-being among the clinical nurses were surveyed using the Mindful Attention Awareness Scale, the Emergency Department Nurse Work Immersion Experience Questionnaire, and the Medical Workers' Professional Well-being Scale, respectively. A structural equation model was constructed using AMOS 26.0 software. Results The total scores of mindfulness level, work immersion, and professional well-being among clinical nurses were (68.9±11.4), (134.1±20.2), and (89.1±12.6) points, respectively. The total score of mindfulness level was positively correlated with work immersion and professional well-being [correlation coefficients (r) were 0.566 and 0.344, respectively, both P<0.01], and the total score of work immersion was positively correlated with professional well-being (r=0.431, P<0.01). The mediating effect of mindfulness in work immersion and professional well-being was 0.059, with a 95% confidence interval of (0.014-0.108), accounting for 19.5% of the total effect. Conclusion The level of mindfulness among clinical nurses is relatively high. Mindfulness plays a partial mediating role between work immersion and professional well-being.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APC^min/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

OBJECTIVE To compare the efficacy and safety of Cefazolin sodium for injection， Cefuroxime sodium for injection， and Ceftazidime for injection from nationally organized centralized drug procurement （hereinafter referred to as “centralized procurement”） and non-centralized procurement in patients with bacterial infection. METHODS The case data of hospitalized patients who had used 3 kinds of Cephalosporins for injection from centralized procurement or non-centralized procurement in the treatment of bacterial infections were retrospectively collected from 19 medical institutions in Kunming from January 2020 to September 2022. After balancing the baseline differences between the groups with the propensity score matching method， the effectiveness and safety differences of 3 kinds of Cephalosporins for injection from centralized procurement or non- centralized procurement were compared respectively. RESULTS After balancing the baseline differences among the groups， 394 cases in each group of Cefazolin sodium for injection from centralized procurement or non-centralized procurement， 472 cases in each group of Cefuroxime sodium for injection from centralized procurement or non-centralized procurement， 504 cases in group of Ceftazidime for injection from centralized procurement and 590 cases in group of non-centralized procurement were included in the analysis. In terms of effectiveness， there were no significant differences in clinical response rate， 72 h response rate， bacterial clearance rate， and the recovery rate of body temperature， white blood cell count， neutrophil count， neutrophil percentage， C-reactive protein， procalcitonin recovery between the centralized procurement group and non-centralized procurement group of Cefazolin sodium for injection and Cefuroxime sodium for injection （P＞0.05）. The proportion of patients in centralized procurement group of Ceftazidime for injection with C-reactive protein restored to normal reference range was significantly higher than that in non-centralized procurement group （46.9% vs. 27.9%， P＜0.05）， but there were no statistically significant differences in other effectiveness indicators among groups （P＞0.05）. In terms of safety， there was no statistical difference in the incidence of adverse drug reactions between centralized procurement group and non-centralized procurement group of 3 kinds of Cephalosporins for injection （P＞0.05）； the incidence of platelet count reduction in centralized procurement group of Cefazolin sodium for injection was significantly higher than non-centralized procurement group （20.7% vs. 7.1%， P＜0.05）， the incidence of eosinophilia elevation in centralized procurement group of Ceftazidime for injection was significantly higher than non-centralized procurement group （5.3% vs. 1.9%， P＜0.05）. In addition， there was no statistically significant difference in the abnormal rates of other laboratory indicators among the three types of injection Cephalosporins （P＞ 0.05）. CONCLUSIONS The efficacy of 3 kinds of Cephalosporin for injection from centralized procurement is not inferior to non- centralized procurement varieties， and the safety is equivalent to that of non-centralized procurement varieties.

OBJECTIVE To explore the changes of brain white matter of the patients with obstructive sleep apnea-hypopnea syndrome(OSAHS)with magnetic resonance diffusional kurtosis imaing(DKI).METHODS There were 38 patients with OSAHS examined by polysomnogram(PSG)from November 2017 to June 2021,and 32 non-OSAHS controls matched in gender and age who were included in this study.All the subjects were scanned by DKI.The different encephalic regions through comparing kurtosis fractional anisotropy(KFA)values of all encephalic regions between the two groups were found,and the relationship between the KFA values of the different encephalic regions in OSAHS patients and the apnea-hypopnea index(AHI),lowest saturation oxygen(LSaO2)and the percent of the total record time spent below 90%oxygen saturation(TS90%)in PSG were analyzed.RESULTS The KFA values of white matter fiber tracts in corpus callosum,bilateral corona radiata,cingulate gyrus,right superior cerebellar peduncle and inferior cerebellar peduncle of OSAHS group were obviously lower than control group(P<0.05).After controlling for age and body mass index(BMI),the partial correlation between AHI and the KFA values of corpus callosum,left posterior corona radiata,right anterior corona radiata,cingulate gyrus in OSAHS group were also negative(r=-0.344,-0.380,-0.406,-0.53,P<0.05).The partial correlation between LSaO2 and the KFA values of corpus callosum,left posterior corona radiata,right anterior corona radiata,cingulate gyrus,right superior cerebellar peduncle in OSAHS group were also positive(r=0.366,0.406,0.446,0.404,0.342,P<0.05).The partial correlation between TS90%and the KFA values of corpus callosum,left posterior corona radiata,right anterior corona radiata,cingulate gyrus,right superior cerebellar peduncle and inferior cerebellar peduncle in OSAHS group were also negative(r=-0.414,-0.352,-0.355,-0.336,-0.456,-0.360,P<0.05).CONCLUSION Recurrent apnea and hypoxemia at night of OSAHS patients can cause damage to white matter fibers in parts of encephalic regions.

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are currently the first-line standard of care for patients with non-small cell lung cancer (NSCLC) that harbor EGFR mutations. Nevertheless, resistance to EGFR-TKIs is inevitable. In recent years, although immune checkpoint inhibitors (ICIs) have significantly shifted the treatment paradigm in advanced NSCLC without driver mutation, clinical benefits of these agents are limited in patients with EGFR-mutated NSCLC. Compared with wild-type tumors, tumors with EGFR mutations show more heterogeneity in the expression level of programmed cell death ligand 1 (PD-L1), tumor mutational burden (TMB), and other tumor microenvironment (TME) characteristics. Whether ICIs are suitable for NSCLC patients with EGFR mutations is still worth exploring. In this review, we summarized the clinical data with regard to the efficacy of ICIs in patients with EGFR-mutated NSCLC and deciphered the unique TME in EGFR-mutated NSCLC.

Objective We aimed to investigate the effects of Biejiajian Pills on MHCC-97H hepatoma cells and whether Biejiajian Pills regulate the epidermal growth factor receptor (EGFR)/mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) signaling pathway through miR-885-5p.Methods SPF SD rats (n = 10) were randomly divided into the blank group and the Biejiajian Pills (1.1 g/kg) group to prepare blank and Biejiajian Pills-containing serum. MHCC-97H cells in the logarithmic growth phase were divided into the model group, blank serum groups with different concentrations (5％, 10％, 15％, and 20％), the serum containing Biejiajian Pills group, and the blank group without cells. Cell proliferation was detected by the CCK-8 assay, and the optimal intervention time and concentration of drug-containing serum were screened. MHCC-97H cells were divided into the blank control group (no intervention), the Biejiajian Pills-containing serum group (20％ Biejiajian Pills-containing serum), the miR-885-5p mimics group (transfected with miR-885-5p mimics), the miR-NC group (transfected with miR-885-5p NC), and the Biejiajian Pills-containing serum + miR-885-5p mimics group (treated with 20％ Biejiajian Pills-containing serum and transfected with miR-885-5p mimics). Cells in each group were cultured for 72 hours. A dual luciferase reporter assay was conducted to verify the targeting relationship between miR-885-5p and EGFR. Cell proliferation was detected by the CCK-8 assay, cell migration and invasion abilities were detected by the cell scratch assay and the Transwell invasion assay. Annexin V-APC/PI double staining was performed to detect the apoptosis level, and real-time fluorescence quantitative PCR (RT-qPCR) analysis was conducted to determine the mRNA expression levels of miR-885-5p, EGFR, MEK, and ERK1/2. The expression levels of EGFR, p-EGFR, MEK, p-MEK, ERK1/2, p-ERK1/2, matrix metalloproteinase 1 (MMP1), and CyclinD1 were determined by Western blotting analysis. The subcutaneous tumor model of MHCC-97H hepatoma cells in nude mice was established by subcutaneous injection to observe the inhibitory effect of Biejiajian Pills of different doses(0.55,1.1,2.2 g/kg).Results The optimal concentration and intervention time of Biejiajian Pills-containing serum were 20％ and 72 hours, respectively. Meanwhile, the dual luciferase reporter assay showed that miR-885-5p could directly target EGFR. No statistical significances between the blank control group and the miR-NC group were observed (P>0.05). Compared with the blank control group, the proliferation rates of MHCC-97H hepatoma cells in the Biejiajian Pills-containing serum group, the miR-885-5p mimics group, and the Biejiajian Pills-containing serum + miR-885-5p mimics group were significantly decreased (P<0.01), and their migration and invasion abilities were significantly decreased (P<0.05, P<0.01). At the same time, the protein expression levels of CyclinD1 and MMP1, which are closely related to cell proliferation and invasion, were significantly downregulated (P<0.05, P<0.01). The proportions of late apoptotic cells and the proportion of total apoptotic cells were significantly increased (P<0.01). In the Biejiajian Pills-containing serum group, the miR-885-5p mimics group, and the Biejiajian Pills-containing serum + miR-885-5p mimics group, miR-885-5p mRNA was significantly upregulated (P<0.01) and EGFR, MEK, and ERK1/2 were significantly downregulated at the mRNA level (P<0.05, P<0.01). EGFR, MEK, and ERK1/2 phosphorylation was inhibited (P<0.01), and the Biejiajian Pills-containing serum + miR-885-5p mimics group showed the best effect (P<0.05, P<0.01). The subcutaneous liver tumor model in nude mice verified that Biejiajian Pills can inhibit tumor growth in a dose-dependent manner. Conclusion Biejiajian Pills can promote apoptosis of MHCC-97H hepatoma cells and inhibit their proliferation, invasion, and migration. The mechanism may be related to the targeted regulation of the EGFR/MAPK/ERK signaling pathway by miR-885-5p.

Objective:To explore the brain white matter damage in patients with moderate to severe obstructive sleep apnea hypopnea syndrome(OSAHS) using diffusional kurtosis imaging(DKI), and to analyze its relationship with anxiety, depression and cognitive impairment in patients.Methods:This was a retrospective case-control study. Fifty confirmed cases (47 males and 3 females) of moderate to severe OSAHS diagnosed by polysomnography(PSG) from November 2017 to December 2022 were selected as OSAHS group(age range from 22 to 65 years old, with median age of 40 years old), and 32 healthy controls(27 males and 5 females) of non-OSAHS diagnosed by PSG were selected as control group(age range from 19 to 56 years old, with median age of 34 years old). DKI scanning, Beck Anxiety Inventory(BAI), Beck Depression Inventory-Ⅱ(BDI-Ⅱ), and Montreal cognitive assessment(MoCA) scores were performed in all subjects. Differences in kurtosis fractional anisotropy(KFA) of various brain regions were compared between the two groups to identify differential brain regions. Correlations were analyzed between KFA reduction and anxiety, depression, and cognitive impairment in OSAHS patients. To study the correlation between brain injury and anxiety, depressive mood, and cognitive dysfunction, statistical methods such as non-parametric tests for two independent samples, chi-square tests, and partial correlation analysis, were used to analyze the evaluation indicators of the two groups.Results:The KFA values in right external capsule, left anterior corona radiata, right anterior corona radiata, left posterior corona radiata, right posterior corona radiata, left superior corona radiata, right superior corona radiata, left superior longitudinal fasciculus, right superior longitudinal fasciculus, genu of corpus callosum, splenium of corpus callosum, body of corpus callosum, posterior cingulate gyrus of moderate to severe OSAHS group were all lower than those in the control group( t=-2.247, -3.028, -3.955, -4.871, -2.632, -2.594, -2.121, -2.167, -3.129, -2.015, -2.317, -2.313, -2.152, P<0.05). For the moderate to severe OSAHS group, the correlation between AHI and KFA values of right posterior corona radiata, right superior corona radiata, left anterior corona radiata, left posterior corona radiata, left superior corona radiata, left superior longitudinal fasciculus, genu of corpus callosum, body of corpus callosum, splenium of corpus callosum were all negative( r=-0.378, -0.307, -0.337, -0.343, -0.341, -0.613, -0.390, -0.384, -0.396, P<0.05). The correlation between LSO 2 and KFA values of right anterior corona radiata, right posterior corona radiata, right superior corona radiata, right superior longitudinal fasciculus, left anterior corona radiata, left posterior corona radiata, left superior corona radiata, left superior longitudinal fasciculus, genu of corpus callosum, body of corpus callosum, splenium of corpus callosum, posterior cingulate gyrus were all positive( r=0.330, 0.338, 0.425, 0.312, 0.433, 0.358, 0.410, 0.459, 0.473, 0.659, 0.489, 0.356, P<0.05). The correlation between BAI scores and KFA values of right external capsule, right anterior corona radiata, left posterior corona radiata, left superior corona radiata, body of corpus callosum, splenium of corpus callosum were all negative( r=-0.306, -0.372, -0.296, -0.346, -0.318, -0.386, P<0.05). The correlation between BDI-Ⅱ scores and KFA values of right superior corona radiata, right superior longitudinal fasciculus, left anterior corona radiata, genu of corpus callosum, body of corpus callosum, splenium of corpus callosum were all negative( r=-0.334, -0.289, -0.309, -0.310, -0.503, -0.469, P<0.05). The correlation between MoCA scores and KFA values of right posterior corona radiata, right superior longitudinal fasciculus, left anterior corona radiata, left superior corona radiata, left superior longitudinal fasciculus, genu of corpus callosum, body of corpus callosum, splenium of corpus callosum were all positive( r=0.368, 0.431, 0.324, 0.410, 0.469, 0.384, 0.369, 0.309, P<0.05). Conclusions:With the aggravation of OSAHS, the damage to some brain regions becomes more pronounced in moderate to severe OSAHS patients. These damage brain functional areas are closely related to the anxiety, depression, and cognitive impairment of patients.
