Objective To analyze the influence of Helicobacter pylori (Hp) infection on the risk of colorectal adenomatous polyps in patients with type 2 diabetes mellitus (T2DM). Methods A total of 306 patients with T2DM who were treated in the hospital from April 2021 to April 2024 were enrolled as the study subjects. According to whether colorectal adenomatous polyps occurred, the enrolled patients were divided into adenomatous polyp group and non-adenomatous polyp group. The risk factors of colorectal adenomatous polyps in T2DM patients were discussed by univariate and Logistic multivariate regression analyses. The predictive value of Hp on the occurrence of colorectal adenomatous polyps was explored by receiver operating characteristic (ROC) curve. Results Among 306 T2DM patients, there were 142 cases of colorectal adenomatous polyps, with an incidence rate of 46.41%. After logistic analysis, it was found that Hp infection, concurrent gallbladder disease, fatty liver, alcohol drinking history and insulin use were independent influencing factors for colorectal adenomatous polyps (OR: 5.518, 95%CI: 2.806-10.850; OR: 2.782, 95%CI: 1.406-5.502; OR: 3.702, 95%CI: 1.684-8.141; OR: 2.125, 95%CI: 1.140-3.964; OR: 5.398, 95%CI: 2.528-11.525, P<0.05). ROR curve analysis indicated that the area under the curve (AUC), sensitivity and specificity of Hp infection in predicting colorectal adenomatous polyps were 0.611, 38.73% and 83.54%. Conclusion The occurrence of colorectal adenomatous polyps in patients with T2DM is affected by many factors among which Hp infection has obvious predictive value on its risk.

OBJECTIVES: Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS. METHODS: A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions. RESULTS: Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS. CONCLUSIONS These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

Objective:To evaluate the expression of B7-H3 and CD133 in colorectal cancer(CRC),colorectal polyps,and normal colorectal mucosa and investigate their roles in the development and prognosis of CRC.Methods:Immunohistochemistry was used to detect the ex-pression of B7-H3 and CD133 in 195 CRC,76 villous/tubulovillous adenoma,64 tubular adenoma,30 non-adenomatous polyp,and 10 nor-mal colorectal mucosa samples obtained from The Second Affiliated Hospital of Zhengzhou University between October 2012 and April 2017 and Pengan County People's Hospital between January 2017 and May 2019.Patient age,sex,and immunohistochemical staining results of B7-H3,CD133,and carcinoembryonic antigen were incorporated as risk factors to establish a CRC survival prediction model.Results:B7-H3 and CD133 expression showed an increasing trend from normal mucosa to non-adenomatous polyps,tubular adenomas,villous/tubulovil-lous adenomas,and CRC(P<0.05),and correlated with adenoma size.It was also associated with CRC metastasis and shorter survival(P<0.05).Furthermore,the expressions of B7-H3 and CD133 demonstrated a value in the CRC survival prediction model,in the training as well as validation set.Conclusions:The immune regulator B7-H3 and cancer stem cell marker CD133 are associated with poor prognosis in CRC,and their expressions may serve as predictive factors for CRC prognosis.

Turning to critical illness is a common stage of various diseases and injuries before death. Patients usually have complex health conditions, while the treatment process involves a wide range of content, along with high requirements for doctor′s professionalism and multi-specialty teamwork, as well as a great demand for time-sensitive treatments. However, this is not matched with critical care professionals and the current state of medical care in China. Telemedicine, which shortens the distance of medical professionals and the gap of disease diagnosis and treatments in various regions through electronic information, can effectively solve the current problem. Therefore, there is an urgent need to develop a standardized, high-quality visualization telemedicine round system .Therefore, experts have been organized to search domestic and foreign literature on telemedicine round for critically ill patients and to form this consensus based on clinical experiences so as to further improve the level of critical care treatments in regions.

Objective To perform an economic evaluation of ilaprazole in the treatment of patients with peptic ulcer bleeding and low-risk stigmata,and to provide a reference for drug selection.Methods From a societal perspective,we used decision analysis to evaluate the cost and effectiveness of ilaprazole and omeprazole in treating peptic ulcer bleeding patients dur-ing hospital stays.The probabilities of model nodes were taken from phase Ⅲ clinical trial research results,while cost data came from national medical insurance prices,published literature,and hospital databases.Sensitivity analysis and scenario analysis were performed to test the stability of the results.Results A cost minimization analysis was performed.Under the basic setting,the cost of the ilaprazole group was 4 038.99 yuan,and that of the omeprazole group was 3 837.61 yuan,which means that the cost of the ilaprazole group was 201.38 yuan higher.Sensitivity analysis showed that the results were stable.Scenario analysis showed that ilaprazole was more cost-effective than the innovator drug of omeprazole.Conclusion Ilaprazole was less economical than ome-prazole in the treatment of peptic ulcer bleeding patients with low-risk stigmata.

Objective:To investigate the current state of oral health knowledge,attitude and practice(KAP)of plateau military personnels and to analyze the disease condition,aiming to explore new strategies for enhancing oral health.Methods:A question-naire was developed to survey 500 individuals at high altitudes(≥3 000 m)and 500 at low altitudes(≤1 000 m)regarding their oral health KAP,with 100 subjects randomly selected from each group for oral examinations.Logistic regression analysis was ap-plied to examine the correlation between KAP and disease status.Based on these findings,a survey of the oral health needs of mili-tary personnels was conducted in conjunction with their KAP.And an innovative training system,"Perception-Comprehension-Inte-gration"(PCI),was established to improve the competencies of primary healthcare providers,with its effectiveness being evaluated.Results:The high altitude group had significantly lower rates of overall oral health awareness(53.61％),positive attitude(55.00％)and positive practice(40.29％)compared with the low altitude group(P＜0.05);the incidence in high altitude group experiencing dental caries(73％),wedge-shaped defects(34％),pericoronitis(16％),gingival bleeding(74％),dental calculus(81％)and cheilitis(37％)were significantly higher than those in the low altitude group(P＜0.05).There was a significant nega-tive correlation between KAP scores and disease prevalence.The subjects in both groups showed a substantial demand(exceeding 70％)for oral health.The innovative PCI training system has markedly strengthened the health personnel's compre-hensive preventive and health care capabilities.Conclu-sion:The oral health status of plateau military personnels is in dire need of enhancement.And the PCI training sys-tem is poised to serve as a novel approach to tackling this critical concern.

Background and purpose:Prostate cancer and breast cancer are highly prevalent malignant tumors,and there occurrence and development are related to the tumor suppressor genes phosphatase and tensin homolog deleted on chremosome ten(Pten)and the transformation related protein 53 gene(Trp53).The loss of function of Trp53 is closely related.The simultaneous loss of the two can accelerate the malignant progression of tumors and induce therapeutic resistance.The gene-edited spontaneous tumor model of mice based on the Cre-loxP system is a key tool for studying the mechanism of cancer.Studies have shown that prostate-specific promoter(probasin,Pbsn)-driven iCre recombinase(Pbsn-iCre)can induce spontaneous prostate cancer in male mice,but its role in female breast cancer and transgender expression characteristics have not yet been clarified.In this study,we constructed Ptenfl/fl;Trp53fl/fl;Pbsn-iCre+transgenic mouse model which was designed to explore its spontaneous tumor phenotype in prostate cancer and breast cancer,and to verify the expression characteristics of Pbsn in breast tissue.Methods:The Ptenfl/fl;Trp53fl/fl;Pbsn-iCre+mouse model was established using Cre-loxP system by hybridization and continuous backcross screening with Ptenfl/fl mouse,Trp53fl/flmouse,and Pbsn-iCre+mouse(Ethical No.:FUSCC-IACUC-2025115).Pten,Trp53 and Pbsn-iCre genotypes were verified by polymerase chain reaction and agarose gel electrophoresis.The incidence of tumor in transgenic mice was monitored,and the histopathological characteristics of tumor were evaluated by hematoxylin-eosin staining.The protein levels of Pten and p53 in prostate and breast tumor tissues were analyzed by immunohistochemistry,and the distributions of Pbsn in breast,prostate,ovary,heart,liver and kidney were detected.Results:Ptenfl/fl;Trp53fl/fl;Pbsn-iCre+male mouse developed spontaneous prostate tumor at age of 5 month,and female mouse developed spontaneous breast tumor at age of 6 months.The pathological manifestations of prostate cancer were invasive acinar adenocarcinoma structure with glandular structure disorder and basement membrane destruction.The pathological manifestations of breast cancer were invasive ductal carcinoma with ductal epithelial dysplasia and interstitial lymphocyte infiltration.Immunohistochemistry confirmed the complete deletion of Pten and p53 proteins in prostate and breast tumor tissues,which verified the prostate and mammary gland specific gene knockout effect.Immunohistochemistry also confirmed that Pbsn protein was specifically expressed in prostate acinar epithelial cells,ovarian tissue,and mammary duct epithelial cells,but not in heart,liver and kidney.Conclusion:Pbsn-iCre is functionally expressed in female mammary glands,and the simultaneous loss of Pten/Trp53 induced by Pbsn-iCre may drive the development of prostate cancer in male and breast cancer in female mouse.

Objective:To explore the developmental trajectory and influencing factors of self-management behavior among stroke patients.Methods:A total of 478 ischemic stroke patients admitted to the department of neurology of a grade-Ⅲ hospital in Henan Province from July 2023 to June 2024 were selected as the investigation objects. Baseline data of patients were collected using the general situation questionnaire, stroke knowledge questionnaire, stroke health belief scale, stroke self-management behavior scale and self-rating depression scale. The self-management behavior level of patients was assessed at discharge, 1 month, 3 months and 6 months after discharge. Mplus 7.0 software was used to conduct trajectory analysis of stroke patients' self-management behaviors, and multiple Logistic regression analysis was used to analyze the influencing factors associated with the development trajectory types of different stroke self-management behaviors.Results:The self-management behavior scores of stroke patients at discharge, 1 month, 3 months and 6 months after discharge were 206.59(167.59, 230.57), 169.59(129.73, 196.73), 149.82(120.89, 171.48), and 147.14(123.02, 181.64), respectively. Four trajectory categories were described. Category 1 was low-level pattern of initial decrease followed by stabilization, accounting for 16.95%(81/478)( P<0.001, intercept=2.701). Category 2 was low-level pattern of initial decrease followed by increase, accounting for 12.97%(62/478)( P<0.001, intercept =2.696). Category 3 was medium-level pattern of initial decrease followed by stabilization, accounting for 57.11%(273/478)( P<0.001, intercept =3.829). Category 4 was high-level pattern of initial decrease followed by increase, accounting for 12.97%(62/478)( P<0.001, intercept=4.366). The self-management behavior of stroke patients with low level of stroke knowledge, low level of health belief, aged 60 to 70 years old, residence in rural areas and middle school and below education level were more likely to belong to the low level group(all P<0.05). Patients with low depression in the low level group were more likely to be classified as low-level pattern of initial decrease followed by increase( P<0.05). Conclusion:The trajectory category of self-management behavior could be predicted by stroke knowledge level, health belief level, age, place of residence, educational background and depression. Their self-management behavior level may be improved through targeted interventions according to the characteristics of different trajectory categories.

Objective:To understand the feelings and experiences of patients with dizziness caused by cerebrovascular diseases, and to provide a reference basis for the development of nursing intervention measures.Methods:Semi-structured interviews were carried out from November 2024 to February 2025 by phenomenology method. The patients with dizziness caused by cerebrovascular diseases who were hospitalized in the First Affiliated Hospital of Zhengzhou University were selected by purposive sampling method. The interview data were analyzed by the Colaizzi 7-step analysis method to summarize and extract the themes.Results:Finally, 16 patients with dizziness caused by cerebrovascular diseases were interviewed, including 6 males and 10 females, aged 43 to 73 years. The feeling and experience of patients with dizziness caused by cerebrovascular diseases could be summarized into three themes: persistent physical symptoms (physiological function imbalance, the superposition of multiple symptoms); patients had cognitive biases (symptom risk cognitive bias, symptom knowledge cognitive bias, drug effect cognitive bias); patients' self-perceived burden was obvious(physical burden, emotional burden, and economic burden).Conclusions:The patients with dizziness caused by cerebrovascular diseases show multi-dimensional characteristics, and there are many burdens and needs in physiological, psychological and social aspects. We should pay attention to the symptom experience and psychological feelings of such patients, and give targeted health education and multi-dimensional social support.
