The prevalence and factors of willingness to accept circumcision among MSM in Maanshan City, China.

To investigate the prevalence of male circumcision and the willingness to undergo male circumcision and influencing factors among MSM in Maanshan City, we conducted a cross-sectional study from June 2016 to December 2019. Respondent-driven sampling (RDS) was used to recruit participants. Influential factors of willingness to accept circumcision were identified by a multivariable logistic regression model. The multivariable logistic regression model revealed that five variables were independent influential factors for willingness to participate. The factors include that used condoms during last anal intercourse (OR = 1.87, 95% CI:1.03-3.41, P = 0.04), sex with female sex partners (OR = 0.499, 95% CI:0.298-0.860, P = 0.012, level of education (junior college: OR = 0.413, 95% CI:0.200-0.854, P = 0.017; bachelor's degree or higher: OR = 0.442, 95% CI:0.208-0.938, P = 0.033), condom use during oral sex in the last six months (OR = 4.20, 95% CI:1.47-12.0, P = 0.007) and level of knowledge of PrEP (OR = 5.09, 95% CI:1.39-18.7, P = 0.014). Given the willingness of MSM to accept circumcision was low in China, establishing a proper understanding of circumcision is essential if it is to be used as a strategy to prevent HIV infection among MSM. Therefore, publicity and education on the operation should be strengthened to increase the willingness to undergo male circumcision.

MFCC-CNN: A patient-independent seizure prediction model.

BACKGROUND: Automatic prediction of seizures is a major goal in the field of epilepsy. However, the high variability of Electroencephalogram (EEG) signals in different patients limits the use of prediction models in clinical applications. METHODS: This paper proposes a patient-independent seizure prediction model, named MFCC-CNN, to improve the generalization ability. MFCC-CNN model introduces Mel-Frequency Cepstrum Coefficients (MFCC) features and Linear Predictive Cepstral Coefficients (LPCC) features concentrated in the low frequency region, which contains more detailed information. Convolutional neural network (CNN) is used to construct a seizure prediction model. RESULTS: Experimental results showed that the proposed model obtained accuracy of 96 % , sensitivity of 92 % , specificity of 84 % and F1-score of 85 % for 24 cases in CNHB-MIT dataset. The overall performance of MFCC-CNN model is better than the other models. CONCLUSION: MFCC-CNN model does not need to be specifically customized for different patients. As a patient-independent seizure prediction model, it has good generalization ability.

Prevalence and factors associated with late diagnosis among older adults living with HIV in liuzhou, China: 2010-2020.

This paper aimed to quantify and characterize the prevalence and associated factors for late diagnosis in older adults living with human immunodeficiency virus (HIV) in Liuzhou, China, from 2010 to 2020. The characteristics of older adults living with HIV were described separately in time, space and population. Multivariate logistic regression analysis evaluates the factors influencing late diagnosis in HIV-positive adults ≥ 50 years of age. The majority of older adults living with HIV were over 60 years old, male, and with CD4 counts < 200 cells/µl at diagnosis, with most late diagnoses being more likely to report heterosexual transmission. These two factors may potentially provide a positive influence on late diagnosis: older and CD4 counts < 500 cells/µl. In contrast, females and those with homosexual or other transmission provide a negative. These results suggest that late diagnosis of HIV-positive adults ≥ 50 years of age remains a severe and growing epidemiological issue.

Anlotinib reduces the suppressive capacity of monocytic myeloid-derived suppressor cells and potentiates the immune microenvironment normalization window in a mouse lung cancer model.

By exploring the effects of an antiangiogenic small molecule drug named anlotinib on the levels of myeloid-derived suppressor cells (MDSCs) in a mouse xenograft model of lung cancer, the role of anti-angiogenesis in remodeling the immune microenvironment was discussed. In addition, the impact of anlotinib on the normalization of the immune microenvironment and time window was examined, providing a theoretical basis for the optimization of clinical strategies applying anlotinib combined with PD-1 inhibitors. On the basis of the LLC mouse xenograft model, MDSCs and MDSCs + immune microenvironment were examined in tissues, respectively, according to different samples. The former observation included the control (group A) and anlotinib monotherapy (group B) groups; the latter also included the control (group C) and anlotinib monotherapy (group D) groups. The levels of MDSCs in peripheral blood at different time points were analyzed by flow cytometry, and the levels of MDSCs in tissue samples at different time points were evaluated by immunofluorescence and immunohistochemistry. The volumes of subcutaneous xenografts were significantly smaller in the anlotinib treatment group compared with the control group ( P < 0.005). Flow cytometry showed that compared with the control group, the intratumoral percentages of total MDSCs ( P < 0.01) and mononuclear-MDSCs ( P < 0.05) were significantly decreased on days 3 and 17 after anlotinib treatment in peripheral blood samples; however, there was no significant difference in granulocytic-MDSCs changes between the experimental and control groups. Immunofluorescence showed that the levels of MDSCs in both the experimental and control groups reached the lowest points 10 days after drug administration, and were significantly lower in the experimental group than in the control group ( P < 0.05). Anlotinib reduces the levels of MDSCs in the mouse xenograft model of lung cancer, with the characteristics of time window. This study provides a basis for further exploring strategies for anti-angiogenic treatment combined with immunotherapy in lung cancer based on time-window dosing.

An HIV stochastic model with cell-to-cell infection, B-cell immune response and distributed delay.

In this study, a delayed HIV stochastic model with virus-to-cell infection, cell-to-cell transmission and B-cell immune response is proposed. We first transform the stochastic differential equation with distributed delay into a high-dimensional degenerate stochastic differential equation, and then theoretically analyze the dynamic behaviour of the degenerate model. The unique global solution of the model is given by rigorous analysis. By formulating suitable Lyapunov functions, the existence of the stationary Markov process is obtained if the stochastic B-cell-activated reproduction number is greater than one. We also use the law of large numbers theorem and the spectral radius analysis method to deduce that the virus can be cleared if the stochastic B-cell-inactivated reproduction number is less than one. Through uncertainty and sensitivity analysis, we obtain key parameters that determine the value of the stochastic B-cell-activated reproduction number. Numerically, we examine that low level noise can maintain the number of the virus and B-cell populations at a certain range, while high level noise is helpful for the elimination of the virus. Furthermore, the effect of the cell-to-cell infection on model behaviour, and the influence of the key parameters on the size of the stochastic B-cell-activated reproduction number are also investigated.

Survival times of HIV/AIDS in different AIDS Diagnostic and Treatment Guidelines from 2006 to 2020 in Liuzhou, China.

BACKGROUND: To compare the survival rates of four timing of treatment initiation for people living with HIV/AIDS provided in China in 2006, 2011, 2015, and 2018, and to investigate the factors impacting survival time. METHODS: A people living with HIV/AIDS retrospective cohort study was in Liuzhou City from April 2006 to December 2020. The information was obtained from the National Comprehensive AIDS Prevention and Control Information System. Life tables and the Kaplan-Meier method were used to calculate participant survival rates and time. The univariate and multivariate Cox regression models were used to investigate the factors related to survival. RESULTS: 18,543 participants were included in this study. In four periods, the 1-year survival rates were 81%, 87%, 95%, and 95%. The 2-year survival rates were 76%, 85%, 93%, and 94%. The 3-year survival rates were 73%, 84%, 92%, and 94%. Results of multivariate Cox regression showed that sex, age of HIV diagnosis, ethnicity, household registration, occupation, marital status, the timing of treatment, education level, route of HIV transmission, whether receiving antiretroviral therapy (ART), and the count of CD4+T cells at baseline (count of CD4+T cells at HIV diagnosis) were factors that are significantly correlated with mortality caused by HIV infection. CONCLUSIONS: With the Guidelines updated from 2006 to 2020, the 1-, 2-, and 3-year survival rates of people living with HIV/AIDS in four periods tended to increase. The timing of treatment initiation of the updated edition of the AIDS Diagnostic and Treatment Guidelines (Guidelines) significantly prolonged the survival time of people living with HIV/AIDS.

Medical applications of generative adversarial network: a visualization analysis.

BACKGROUND: Deep learning (DL) is one of the latest approaches to artificial intelligence. As an unsupervised DL method, a generative adversarial network (GAN) can be used to synthesize new data. PURPOSE: To explore GAN applications in medicine and point out the significance of its existence for clinical medical research, as well as to provide a visual bibliometric analysis of GAN applications in the medical field in combination with the scientometric software Citespace and statistical analysis methods. MATERIAL AND METHODS: PubMed, MEDLINE, Web of Science, and Google Scholar were searched to identify studies of GAN in medical applications between 2017 and 2022. This study was performed and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Citespace was used to analyze the number of publications, authors, institutions, and keywords of articles related to GAN in medical applications. RESULTS: The applications of GAN in medicine are not limited to medical image processing, but will also penetrate wider and more complex fields, or may be applied to clinical medicine. Eligibility criteria were the full texts of peer-reviewed journals reporting the application of GANs in medicine. Research selections included material published in English between 1 January 2017 and 1 December 2022. CONCLUSION: GAN has been fully applied to the medical field and will be more deeply and widely used in clinical medicine, especially in the field of privacy protection and medical diagnosis. However, clinical applications of GAN require consideration of ethical and legal issues. GAN-based applications should be well validated by expert radiologists.

Thioredoxin-1 inhibits amyloid-ß25-35-induced activation of NLRP1/caspase-1/GSDMD pyroptotic pathway in PC12 cells.

BACKGROUND: Alzheimer's disease (AD), the most common neurodegenerative disease, is charactered by these accepted pathological features, such as ß-amyloid (Aß) plaques outside the neurons and neurofibrillary tangles inside the neurons. In recent years, several studies have demonstrated that pyroptosis is associated with the development of AD process. However, whether Aß25-35 induces pyroptosis is still unclear. Thioredoxin-1 (Trx-1), an intracellular multifunctional protein, showed neuroprotective roles by inhibiting the neurotoxicity of Aß, attenuating the apoptosis of brain neurons and improving the spatial learning and memory ability in AD models. Whether Trx-1 could inhibit pyroptosis in AD needs to be further investigated. METHODS AND RESULTS: In the present study, MTT assay was employed to detected the viability. Western blotting was employed to detect the protein levels. Enzyme linked immunosorbent assay was used to examine the intracellular and extracellular levels of IL-18 and IL-1ß. Chronic Aß25-35 treatment remarkedly compromised the viability of PC12 cells, increased the expression of NOD-like receptor pyrin domain containing 1 (NLRP-1), caspase-1 and gasdermin D (GSDMD), and promoted the extracellular release of interleukin (IL)-18 and IL-1ß. Simultaneously, Aß25-35 treatment also significantly reduced the intracellular protein levels of Trx-1. Pharmacological inhibition of Trx-1 activity further decreased the cell viability, activated the NLRP-1/caspase-1/GSDMD pyroptotic pathway, and exacerbated the extracellular release of IL-18 and IL-1ß. CONCLUSIONS: These data suggest that Trx-1 may play a potential inhibitory effect on Aß25-35-induced pyroptosis.

Constitutive secretory expression and characterization of nitrilase from Alcaligenes faecalis in Pichia pastoris for production of R-mandelic acid.

Nitrilases can directly hydrolyze nitrile compounds into carboxylic acids and ammonium. To solve the current problems of bioconversions using nitrilases, including the difficult separation of products from the resting cells used as the catalyst and high costs of chemical inducers, a nitrilase from Alcaligenes faecalis was heterologously expressed in Pichia pastoris X33. The stable nitrilase-expressing strain No.39-6-4 was obtained after three rounds of screening based on a combined detection method including dot-blot, SDS-PAGE, and western blot analyses, which confirmed the presence of recombinant nitrilase with a molecular mass of about 50 kDa. The temperature and pH optima of the nitrilase were 45°C and pH 7.5, respectively. Cu2+ , Zn2+ , and Tween 80 strongly inhibited the enzyme activity, but the optical purity of the product R-mandelic acid (R-MA) was stable, with practically 100% enantiomeric excess (ee). The nitrilase-producing P. pastoris strain developed in this study provides a basis for further research on the enzyme.

SKA3 is a prognostic biomarker and associated with immune infiltration in bladder cancer.

BACKGROUND: Spindle and kinetochore­associated complex subunit 3 (SKA3) has recently been considered a key regulator of carcinogenesis. However, the connection between SKA3 and immune cell infiltration remains unknown. METHODS: The current study investigated the expression mode, prognostic effect, and functional role of SKA3 in different tumors, particularly bladder cancer using numerous databases, comprising TIMER, GEPIA, HPA, UALCAN, PrognoScan, and Kaplan-Meier Plotter. Differentially expressed gene and enrichment analyses were implemented on SKA3 using R packages "edgR" and "clusterProfiler". Immunohistochemistry was further used to validate the expression of SKA3 gene in bladder cancer. Following that, the relevance of SKA3 expression to immune infiltration level in bladder cancer was evaluated using TIMER. RESULTS: Overall, the level of SKA3 expression in tumor tissue significantly increased than in normal tissue. In bladder cancer and other tumors, patients with high SKA3 expression levels had worse overall survival (OS) (p = 0.016), disease-specific survival (DSS) (p = 0.00004), and disease-free survival (DFS) (p = 0.032). Additionally, the major molecular functions for SKA3 included nuclear division, mitotic nuclear division, mitotic sister chromatid segregation, humoral immune response, and cell chemotaxis. Additionally, SKA3 expression was found to be positively associated with enhanced M2 macrophage and T helper (Th) 2 cell infiltration in bladder cancer. CONCLUSIONS: Our study implies that SKA3 contributes to M2 macrophage and Th2 cell polarization by acting as an oncogene in bladder cancer. SKA3 might be a novel biomarker for evaluating prognosis and immune infiltration in bladder cancer.

Asymptotic behavior of a stochastic SIR model with general incidence rate and nonlinear Lévy jumps.

In this paper, we consider a stochastic SIR epidemic model with general disease incidence rate and perturbation caused by nonlinear white noise and L e ´ vy jumps. First of all, we study the existence and uniqueness of the global positive solution of the model. Then, we establish a threshold λ by investigating the one-dimensional model to determine the extinction and persistence of the disease. To verify the model has an ergodic stationary distribution, we adopt a new method which can obtain the sufficient and almost necessary conditions for the extinction and persistence of the disease. Finally, some numerical simulations are carried out to illustrate our theoretical results.

Upscale production of (R)-mandelic acid with a stereospecific nitrilase in an aqueous system.

(R)-Mandelic acid (R-MA) is a key precursor for the synthesis of semi-synthetic penicillin, cephalosporin, anti-obesity drugs, antitumor agents, and chiral resolving agents for the resolution of racemic alcohols and amines. In this study, an enzymatic method for the large-scale production of R-MA by a stereospecific nitrilase in an aqueous system was developed. The nitrilase activity of the Escherichia coli BL21(DE3)/pET-Nit whole cells reached 138.6 U/g in a 20,000-L fermentor. Using recombinant E. coli cells as catalyst, 500 mM R,S-mandelonitrile (R,S-MN) was resolved into 426 mM (64.85 g/L) R-MA within 8 h, and the enantiomeric excess (ee) value of R-MA reached 99%. During the purification process, pure R-MA with a recovery rate of 78.8% was obtained after concentration and crystallization. This study paved the foundation for the upscale production of R-MA using E. coli whole cells as biocatalyst.

Clinical comparison of the efficacy of three different bowel preparation methods on the infectious complications following transrectal ultrasonography-guided prostate biopsy in nursing practice.

AIMS AND OBJECTIVES: To assess the effects of three different bowel preparation methods on the incidence of infectious complications in patients who underwent transrectal ultrasonography-guided prostate biopsy. BACKGROUND: The standard bowel preparation protocol for prostate biopsy has not been established. DESIGN: A retrospective study in a single centre. METHODS: From January 2013-December 2015, the clinical records of 1,130 patients who underwent prostate biopsy were, respectively, reviewed. All the patients received metronidazole prophylaxis before biopsy. The patients were divided into three groups according to the bowel preparation methods: patients in Group A (n = 402) received only soapy enema; patients in Group B (n = 413) received polyethylene glycol; while patients in Group C (n = 315) received polyethylene glycol plus povidone-iodine enema. Infectious complications were classified as fever (>37.5°C), urinary tract infection and sepsis. The postoperative adverse events were also observed. RESULTS: The overall postbiopsy infectious complications were observed in 48 (4.25%) patients of all the cases, including 23 (5.72%) cases in Group A, 20 (4.84%) cases in Group B and five patients (1.59%) in Group C. There was significant difference among the groups (p = .018). In detail, these infectious complications included 22 (1.95%) cases of fever and 26 (2.30%) cases of urinary tract infection. No sepsis was observed among the total patients. The incidence of adverse events was 14.43% (58/402) occurred in Group A, 25.91% (107/413) in Group B and 26.67% (84/315) in Group C. The difference was statistically significant. CONCLUSIONS: Our study confirmed that combined preparation regimens of polyethylene glycol with povidone-iodine enema could significantly reduce the postbiopsy infection rate. Conventional soapy enema is associated with less adverse events. RELEVANCE TO CLINICAL PRACTICE: Findings of this study provide useful evidence-based information for healthcare professionals. The application of combined preparation regimens of polyethylene glycol with povidone-iodine enema resulted in better improvement in the prevention of postbiopsy infection.

Detection rate of prostate cancer following biopsy among the northern Han Chinese population: a single-center retrospective study of 1022 cases.

BACKGROUND: Prostate cancer is known to have ethnic and regional differences. The study aimed to clinically evaluate the detection rate of prostate cancer on transrectal ultrasonography (TRUS)-guided prostate biopsy and analyze its characteristics among the northern Han Chinese population at a single center. METHODS: Between October 2009 and September 2016, a total of 1027 Chinese men, who had undergone TRUS-guided prostate biopsy at Qingdao Municipal Hospital, were retrospectively analyzed. Prostate biopsies were performed in the case of an abnormally elevated serum PSA level, and/or abnormal digital rectal examination (DRE) findings, and/or suspicious prostatic imaging findings. RESULTS: Of the 1022 men enrolled in the analysis, 438 patients (42.8%) were diagnosed with prostate adenocarcinoma histologically. When serum PSA levels were divided into five subgroups (less than 4.0, 4.0 to 10.0, 10.0 to 20.0, 20.0 to 100.0, and ≥ 100.0 ng/ml), the detection rates of prostate cancer were 12.4, 15.9, 34.1, 66.2, and 93.8%, respectively. With serum PSA levels of 4.0 to 10.0 ng/ml, the cancer detection rates for a normal DRE and a suspect DRE finding were 13.5 and 58.2%, respectively. Accordingly, the cancer detection rates for a normal imaging and a suspect imaging finding were 13.5 and 58.2%, respectively. Besides, a large proportion of the patients were in the clinically advanced stage. CONCLUSIONS: The present study data reported a relatively higher prostate cancer detection rate of 42.8% and that the majority of the patients presented with clinically advanced prostate cancers within a local clinical urologic practice. An early detection and screening program for prostate cancer is of great need to reduce the burden from this disease among the northern Han Chinese population.

Nup62, associated with spindle microtubule rather than spindle matrix, is involved in chromosome alignment and spindle assembly during mitosis.

An increasing number of the active mitotic functions of nucleoporins in the distinct steps of mitosis have been assigned over the past few years. As one of FG-repeats containing nucleoporins, Nup62 has been found to be involved in nuclear transport, cell migration, virus infection, and cell cycle regulation. However, the role and mechanism of Nup62 in mitotic regulation have not been fully revealed. In this paper, it was revealed that a fraction of Nup62 was associated with mitotic spindle microtubule instead of spindle matrix, and the localization of Nup62 in the mitotic spindle depended on its three coiled-coil domains rather than Crm1, although Nup62 strongly interacted with Crm1 during mitosis. Moreover, depletion of Nup62 by small interference of RNA seriously induced the defects of chromosome alignment and spindle assembly although the bipolar spindle was observed in most of the Nup62 knock-down cells. Notably, congression of polar chromosome defect was observed in more than 30% of Nup62 knock-down cells. These findings revealed that Nup62 was a novel mitotic spindle associated nucleoporin and involved in chromosome alignment and spindle assembly.

Nitrilase-catalyzed conversion of (R,S)-mandelonitrile by immobilized recombinant Escherichia coli cells harboring nitrilase.

(R)-(-)-Mandelic acid (R-MA) is widely used both as a versatile intermediate for pharmaceuticals and a resolving agent in chiral resolution processes. In the current study, to improve the stability of operation, recombinant Escherichia coli cells expressing nitrilase from Alcaligenes faecalis were immobilized for the enantioselective hydrolysis of (R,S)-mandelonitrile to R-MA. Different immobilization methods including entrapment matrices, entrapment matrices cross-linked by cross-linking and polymerization agents, and direct cross-linking cells using glutaraldehyde (GA) or bionic silicon were investigated. To facilitate industrial solid-liquid separation, the direct cross-linking recombinant E. coli cells using diatomite/GA/polyethyleneimine with 135.95% relative activity compared with free cells was chosen using water as the reaction medium. The operational stability of the immobilized cells was obviously superior to that of free cells, without significant activity loss after 28 cycles of batch reaction and the successive production of R-MA could reach 1.88 M. Moreover, the immobilized cells showed good storage stability with about 52% relative activity after storing for 30 days at 4 °C. Therefore, the immobilized biocatalyst is very promising for upscale production of optically pure R-MA with high performance and low cost.

Comparative proteomic analysis of anti-cancer mechanism by periplocin treatment in lung cancer cells.

BACKGROUND: Periplocin is used for treatment of rheumatoid arthritis, reinforcement of bones and tendons, palpitations or shortness of breath and lower extremity edema in traditional medicine. Our previous findings suggested that periplocin could inhibit the growth of lung cancer both in vitro and in vivo. But the biological processes and molecular pathways by which periplocin induces these beneficial effects remain largely undefined. METHODS: To explore the molecular mechanisms of periplocin involved in anti-cancer activity, in the present study the protein profile changes of human lung cancer cell lines A549 in response to periplocin treatment were investigated using the proteomics approaches (2-DE combined with MS/MS). Western blot was employed to verify the changed proteins. Interactions between changed proteins were analyzed by STRING. RESULTS: 29 down-regulated protein species named GTP-binding nuclear protein Ran (RAN), Rho GDP-dissociation inhibitor 1 (ARHGDIA), eukaryotic translation initiation factor 5A-1 (EIF5A) and Profilin-1(PFN1), and 10 up-regulated protein species named Heat shock cognate 71 kDa protein (HSPA8),10 kDa heat shock protein (HSPE1), and Cofilin-1(CFL-1) were identified. Among them, GTP-binding nuclear protein Ran (RAN) and Rho GDP-dissociation inhibitor 1 (ARHGDIA) were the most significantly changed (over tenfold). The proteasome subunit beta type-6 (PSMB6), ATP synthase ecto-α-subunit (ATP5A1), Aldehyde dehydrogenase 1 (ALDH1) and EIF5A were verified by immunoblot assays to be dramatically down-regulated. By STRING bioinformatics analysis revealing interactions and signaling networks it became apparent that the proteins changed they are primarily involved in transcription and proteolysis. CONCLUSION: Periplocin inhibited growth of lung cancer by down-regulating proteins, such as ATP5A1, EIF5A, ALDH1 and PSMB6. These findings may improve our understanding of the molecular mechanisms underlying the anti-cancer effects of periplocin on lung cancer cells.

Stenosis Detection and Quantification of Coronary Artery Using Machine Learning and Deep Learning.

The aim of this review is to introduce some applications of artificial intelligence (AI) algorithms for the detection and quantification of coronary stenosis using computed tomography angiography (CTA). The realization of automatic/semi-automatic stenosis detection and quantification includes the following steps: vessel central axis extraction, vessel segmentation, stenosis detection, and quantification. Many new AI techniques, such as machine learning and deep learning, have been widely used in medical image segmentation and stenosis detection. This review also summarizes the recent progress regarding coronary stenosis detection and quantification, and discusses the development trends in this field. Through evaluation and comparison, researchers can better understand the research frontier in related fields, compare the advantages and disadvantages of various methods, and better optimize the new technologies. Machine learning and deep learning will promote the process of automatic detection and quantification of coronary artery stenosis. However, the machine learning and the deep learning methods need a large amount of data, so they also face some challenges because of the lack of professional image annotations (manually add labels by experts).

Effect Analysis of Nurse-Led Cognitive Behavioural Therapy on Patients with Urinary Incontinence after Radical Prostatectomy.

OBJECTIVE: To study the effects of nurse-led cognitive behavioural therapy on anxiety, depression and quality of life in patients with urinary incontinence after radical prostatectomy. METHODS: Patients with urinary incontinence after undergoing radical prostatectomy in our hospital from January 2019 to January 2023 were selected as the research objects. They were divided into the observation and control groups in accordance with whether they received nurse-led cognitive behavioural therapy. The general data of the patients were collected, and the baseline data of the two groups were balanced by propensity score matching. The disease-related knowledge; Urinary catheter indwelling time; Urinary incontinence duration; And scores on the Exercise of Self-Care Agency Scale (ESCA), Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD) and Nursing Effect and Health Questionnaire (SF-36) were compared between the two groups after matching. RESULTS: At discharge, the ESCA, SF-36 and disease cognition scores of the observation group were higher than those of the control group (p < 0.05). The HAMA and HAMD scores of the observation group were lower than those of the control group (p < 0.001), and the total effective rate of the observation group (89.83%) was higher than that of the control group (76.27%) (p < 0.05). CONCLUSIONS: In patients with urinary incontinence after radical prostatectomy, the implementation of nurse-led cognitive behavioural therapy can effectively improve self-care and disease cognition abilities, relieve anxiety and depression and improve quality of life.

Research on the estimation and spatial pattern of net tourism carbon emissions in the Yellow River Basin from 2009 to 2019.

Based on panel data and remote sensing data of cities in the Yellow River Basin in China from 2009 to 2019, and using the tourism carbon footprint and tourism carbon carrying capacity models, the tourism carbon emissions, tourism carbon carrying capacity, and net tourism carbon of 65 cities in the Yellow River Basin were calculated. The balance and dynamic changes in carbon emissions and carbon fixation of urban tourism in the past ten years were compared. The results show that (1) tourism carbon emissions in the Yellow River Basin are generally on the rise, along with a distribution characteristic of downstream > middle reaches > upstream with obvious characteristics of urban agglomeration centrality within the basin; (2) the carbon carrying capacity of tourism is higher than that of tourism. The growth of carbon emissions is relatively slow, showing a spatial distribution pattern of high in the west and low in the east, which is mainly related to the geographical environment and economic development of the city; (3) the tourism carbon emissions and tourism carbon carrying capacity in the upstream areas can basically maintain a balance, but in the middle and lower reaches of the region, they show a carbon surplus. There is a significant positive spatial correlation in urban net tourism carbon emissions, and the clusters are mainly H-H and L-L.
