Objective To analyze the distribution status of the end digits of standardized blood pressure measurement recordings in the clinic and the effectiveness of standardized blood pressure measurement for community hypertension screening. Methods The first visit blood pressure measurement data from the Community Health Service Center in Jing'an District, Shanghai from June 2023 to May 2024 were collected and analyzed. According to different measurement methods, the data were divided into two groups: standardized blood pressure measurement and conventional blood pressure measurement. SPSS 19.0 software was used for data analysis. The differences in the distribution balance of the end digits of blood pressure values and the detection rate of blood pressure elevation between the two different groups were analyzed. Results The frequency range of the end digits of blood pressure recorded values in the standardized pressure measurement group was 9.42% to 10.83%, and the detection rate of elevated blood pressure was 24.89%. The conventional pressure measurement group had a preference of the end digit ^"0^", and the detection rate of elevated blood pressure was only 2.12%. The results of multiple logistic regression analysis showed that gender, age, season, and different blood pressure measurement modes were all influencing factors for the detection rate of elevated blood pressure. Conclusion The standardized blood pressure measurement mode in the clinic is suitable for community hypertension screening and pressure measurement, with higher data quality than the conventional pressure measurement mode.

Objective To assess the nutritional status in elderly patients with chronic renal insufficiency (CRI) and reveal the key factors affecting the nutritional status. Methods A total of 310 elderly patients with CRI who received hospitalization treatment and outpatient follow-up in the hospital from January 2021 to June 2024 were selected as the investigation subjects. The nutritional status of patients was evaluated by mini-nutritional assessment (MNA) questionnaire, and the nutritional status and dietary structure of patients were comprehensively evaluated by anthropometric indicators [height, weight, body mass index (BMI), upper arm circumference, calf circumference], biochemical indicators [serum albumin (ALB), prealbumin (PA), hemoglobin (Hb), transferrin (TF)] and 24-hour dietary review method. According to the investigation results of nutritional status, the patients were divided into good nutrition group (MNA score≥24 points), nutritional risk group (MNA score of 17-23.5 points) and malnutrition group (MNA score<17 points). Univariate analysis was adopted to screen the potential influencing factors of elderly CRI. Multivariate logistic regression model was applied to analyze the influencing factors of malnutrition in elderly CRI patients. Results Among the 325 questionnaires were distributed, but only 310 valid questionnaires were recovered, with an effective recovery rate of 95.38%. Investigation results revealed that among the 310 patients, 29.35% (91 cases) had good nutritional status, and 42.26% (131 cases) had nutritional risk, and 28.39% (88 cases) had malnutrition. Univariate analysis indicated that there were statistical differences in BMI, CRI staging, serum ALB, PA, Hb, TF, protein intake and total calorie intake among the good nutrition group, the nutritional risk group and the malnutrition group (P<0.05). Multivariate logistic regression analysis suggested that low BMI (OR=0.903, 95%CI: 0.867-0.941), high CRI stage (OR=1.091, 95%CI: 1.053-1.130), low serum ALB (OR=0.907, 95%CI: 0.867-0.948), PA (OR=0.918, 95%CI: 0.888-0.949), Hb (OR=0.944, 95%CI: 0.909-0.997), TF (OR=0.912, 95%CI: 0.874-0.952), insufficient protein intake (OR=0.924, 95%CI: 0.882-0.969) and insufficient total calorie intake (OR=0.938, 95%CI: 0.909-0.968) were influencing factors for malnutrition in elderly patients with CRI (all P<0.05). Drawing ROC curve of malnutrition in elderly patients with CRI according to the prediction probability of logistic regression model found that the AUC, sensitivity, specificity, 95%CI and Youden index were 0.976, 93.18%, 92.34%, 0.953-0.990 (P<0.05) and 0.855. Conclusion The incidence rate of malnutrition is high in elderly patients with CRI, and is mainly affected by factors such as low BMI, high CRI stage, low serum ALB, PA, Hb and TF levels and insufficient protein and total calorie intakes. In addition, logistic regression model has high predictive value and can provide a reference for early clinical identification of high-risk population with malnutrition among elderly patients with CRI.

Currently, transcatheter intervention is the preferred treatment for patients with anatomically suitable atrial septal defects. However, the use of nickel-titanium alloy occluders in interventional procedures results in lifelong presence of the implant in the body, leading to complications such as metal allergies and arrhythmias in some patients. To overcome the short-term and long-term complications associated with the presence of metal, and to avoid radiation exposure and metal toxicity, this paper reports a case of successful transcatheter closure of atrial septal defect in a pediatric patient with metal allergies using fully biodegradable occluder under ultrasound guidance, achieving excellent results by interventional therapy.

Objective To evaluate the current situation of disease control in middle-aged and elderly patients with chronic obstructive pulmonary disease (COPD) and analyze the relationship with disease cognition. Methods Among the 360 middle-aged and elderly COPD patients diagnosed and treated in our hospital from January 2022 to June 2024 were retrospectively selected as research subjects, and the COPD Assessment Test Questionnaire (CAT), COPD Patient Knowledge Questionnaire (BCKQ) and the hampion Health Belief Model Scale were used to evaluate disease control, disease cognition and health beliefs in COPD patients. The Pearson chi-square test was used to analyze the relationship between disease control level and disease cognition and health beliefs in older patients with COPD. Results A total of 360 middle-aged and elderly COPD patients, 112 were in the complete control group, 189 were in the partial control group, and 59 were in the uncontrolled group, the disease control rate was 83.61%. The differences in disease cognitive scores, severity cognition, susceptibility cognition, disorder cognition, benefit cognition, health motivation, self-efficacy score and total health belief scores in middle-aged and elderly COPD patients with different disease control conditions are statistically significant. The scores of the complete control group were higher than those of partial control group and uncontrolled group, and the scores of partial control group were higher than those of the uncontrolled group (P <0.05). The disease control level of middle-aged and elderly patients with COPD is positively correlated with disease cognitive level and health belief in all dimensions. The higher the disease control level, the higher the disease cognitive level and health belief in the patient . Conclusions Middle-aged and elderly COPD patients still have insufficient awareness of the disease, and the level of disease control needs to be improved. There is a significant correlation between disease cognition, health beliefs and the level of disease control, and the improved cognitive level may help to improve the disease management and control effect. For middle-aged and elderly COPD patients, the community can provide health education courses, personalized health guidance and self-management training to enhance their awareness of diseases, so as to improve the long-term management of COPD and the quality of life of patients.

Objective To investigate the detection status and risk factors of bacterial pneumonia (BP) in elderly patients with acute ischemic stroke (AIS), and to provide evidence for the prevention and treatment of BP in elderly patients with AIS. Methods The case data of 320 elderly patients with AIS admitted to Xijing Hospital from June 2021 to June 2024 were retrospectively collected and analyzed. The distribution status of pathogenic bacteria of BP in the elderly AIS patients was statistically analyzed, and the risk factors of BP in AIS patients were explored and the predictive value was analyzed. Results Among the 320 elderly AIS patients, 57 cases (17.81%) developed BP. Multivariate logistic stepwise regression analysis showed that concurrent dysphagia [OR (95% CI) = 1.654 (1.240-2.206)], high platelet to lymphocyte ratio (PLR) [OR (95% CI) = 1.418 (1.116-1.801)], high neutrophil to lymphocyte ratio (NLR) [OR (95% CI) = 2.756 (1.197-5.360)], and acute ischemic stroke-associated pneumonia score (AIS-APS) [OR (95% CI) = 3.414 (1.574-7.405)] were independent influencing factors for BP in elderly AIS patients (P<0.05). The combination of the above four factors had the largest area under the curve (AUC) (0.866) in predicting BP in elderly AIS. Conclusion The occurrence of BP in elderly AIS patients is related to dysphagia, high level of PLR, high level of NLR, and high score of AIS-APS. It is necessary to strengthen the early identification and intervention of high-risk factors in clinical practice.

[摘 要] 目的：探讨RNA结合蛋白15（RBM15）通过三磷酸腺苷酶家族蛋白3A（ATAD3A）调控Wnt/β-catenin通路对宫颈癌细胞恶性生物学行为的影响。方法：利用TCGA数据库分析宫颈癌组织中RBM15 mRNA表达水平及其与患者预后的关系。收集2024年1月至10月期间在赣州市人民医院手术切除的32例宫颈癌组织及癌旁组织标本，以及宫颈癌细胞HeLa、MS-751、C-33A和SiHa，通过免疫组化、WB法检测宫颈癌组织和细胞中RBM15的表达水平。利用SRAMP在线数据库筛选ATAD3A mRNA的m6A修饰位点。通过RNA免疫沉淀实验、RNA衰变实验及挽救实验鉴定RBM15与ATAD3A mRNA的相互作用。采用RNA干扰技术和病毒感染技术，在宫颈癌HeLa和SiHa细胞敲低或过表达RBM15和ATAD3A，qPCR和WB法检测mRNA和蛋白表达，CCK-8法、划痕实验和Transwell实验检测各组细胞的增殖、迁移和侵袭能力。结果：宫颈癌组织中RBM15 mRNA和蛋白阳性率均显著高于癌旁组织（均P < 0.001）。宫颈癌HeLa、MS-751、C-33A和SiHa细胞RBM15蛋白表达水平显著高于正常宫颈细胞Ect1/E6E7（均P < 0.01）。RBM15 mRNA高表达组患者5年无进展生存率低于低表达组患者（P < 0.01）。宫颈癌组织中ATAD3A的表达水平显著高于癌旁组织（P < 0.001），RBM15 mRNA与ATAD3A mRNA呈正相关（r = 0.601，P < 0.05）。ATAD3A mRNA的501、5 312、12 137位点存在高可信度的m6A修饰位点。HeLa、SiHa细胞中过表达RBM15后，ATAD3A mRNA和蛋白表达升高，而敲低RBM15后，ATAD3A mRNA和蛋白表达降低（均P < 0.001）。RNA免疫沉淀实验显示，与IgG组相比，RBM15抗体的免疫沉淀中ATAD3A mRNA显著富集（均P < 0.001）。MeRIP-qPCR实验显示，ATAD3A mRNA 501、5 312、12 137位点均存在明显的m6A甲基化富集（均P < 0.001）。RNA衰变实验显示，敲低RBM15能降低HeLa、SiHa细胞ATAD3A mRNA的半衰期和稳定性（均P < 0.001）。敲低HeLa、SiHa细胞RBM15的表达，显著抑制癌细胞的增殖、迁移及侵袭，Wnt/β-catenin通路相关蛋白Wnt3、β-catenin、vimentin表达均显著降低（均P < 0.001）；而过表达ATAD3A可完全逆转上述抑制作用（均P < 0.001）。结论：RBM15通过m6A修饰ATAD3A mRNA调控Wnt/β-catenin信号通路，从而促进宫颈癌细胞增殖、迁移及侵袭。

Objective To investigate the correlation between the concentration of air pollutants (PM₁₀, SO₂, NO₂) and the number of outpatient and emergency visits for pediatric respiratory diseases in a general hospital in Shanghai. Methods Data including pediatric respiratory disease outpatient and emergency visits in a hospital in Pudong New Area of Shanghai from May 1, 2013 to March 20, 2022 were collected. Daily concentration of air pollutants including PM₁₀, SO₂ and NO₂ and meteorological data in Pudong New Area during the same period were collected. A case-crossover study with distributed lag non-linear model was conducted to explore the correlation between air pollutants (PM₁₀, SO₂, NO₂) and the number of outpatient and emergency visits for pediatric respiratory diseases. Results The concentrations of PM₁₀, SO₂ and NO₂ were positively with the number of outpatient and emergency visits for pediatric respiratory diseases. The strongest cumulative effect was observed on six days lag (Lag0-5) for PM₁₀. For a 10 μg/m³ increase of the concentrations of PM₁₀, the corresponding increase of cumulative pediatric respiratory disease outpatients was 1.10% (95%CI:0.97%, 1.23%) in Lag0-5. The strongest cumulative effect was observed on eight days lag (Lag0-7) for SO₂ and NO₂. For a 10 μg /m³ increase of the concentrations of SO₂ and NO₂, the corresponding increase of cumulative pediatric respiratory disease outpatients was 5.64% (95%CI:5.16%, 6.13%) and 5.41% (95%CI:5.15%, 5.66%) in Lag 0-7, respectively. The association of PM₁₀ and SO₂ with the number of pediatric respiratory disease visits in males was significantly stronger than that in females. The impact of PM₁₀ on the number of pediatric respiratory disease visits in children aged 0-6 was higher than that in children aged 7-14, while the impact of SO₂ and NO₂ on the number of pediatric respiratory disease visits in children aged 7-14 was higher than that in children aged 0-6. Conclusion The concentration of ambient PM₁₀, SO₂, and NO₂ is positively correlated with outpatient and emergency visits for pediatric respiratory diseases, with obvious lag and cumulative effect. Boys and children aged 0-6 are more susceptible to the hazard of air pollution.

Objective To investigate the difference of the disease progression in patients with chronic obstructive pulmonary disease (COPD) with different muscle mass levels and the influence of related factors on the disease progression. Methods A total of 308 newly diagnosed patients with COPD from February 2021 to February 2022 were selected for this study. All patients were below moderate COPD. The patients were divided into two groups according to their muscle mass levels: sarcopenia group (98 cases) and control group (210 cases). The diagnostic criteria for sarcopenia were based on sarcopenia diagnostic thresholds: RSMI <7.0kg/m² in men and <5.4kg/m² for women. All subjects were followed up for 4 months to observe the progress of the patient's condition. The correlation between the muscle mass level and pulmonary function level, as well as the results of 6-minute walking test and CAT score was evaluated, and the influence of muscle mass level on the patient's disease progress was analyzed. At the same time, the potential influence of related factors (body fat rate, vitamin D level, etc.) on the condition of patients with different muscle mass levels was discussed. SPSS 19.0 software was used to perform statistical analysis. Results Under the same treatment intervention, the baseline and follow-up lung function improvement levels of patients in the sarcopenia group were lower than those in the control group, and the difference was statistically significant (P<0.05). At the same time, the baseline and follow-up 6-minute walk test results of the patients in the sarcopenia group were also worse than those of the control group, and the difference was statistically significant (P<0.05). Further correlation analysis was carried out between the patient's muscle mass level and the post-treatment pulmonary function indicators and 6MWD test level. The results showed that the muscle mass level was positively correlated with several pulmonary function indicators (FEV1, FEV1% predict) and 6MWD (both P<0.05). Considering the possible influence of other factors on the control and progress of the patient's condition, the present study used follow-up CAT score results to distinguish the prognosis of the patient's condition improvement, and used improvement and non-improvement as dependent variables to analyze the influence of various potential influencing factors. The results of regression model analysis showed that lower baseline muscle mass, women, lower body fat percentage, and lower vitamin D level were the main risk factors. Conclusion Under the same treatment condition, COPD patients with different muscle mass levels improve more slowly when complicated with sarcopenia and have poor prognosis. Women, lower body fat percentage and lower vitamin D level are potential risk factors for poor prognosis.

Objective To understand the epidemiological characteristics and influencing factors of Mycoplasma pneumoniae (MP) infection in children with respiratory tract infection in Yangzhou , and provide theoretical guidance for the prevention of this disease. Methods Pharyngeal swab sample was collected from Children of 21 403 in the Respiratory Infection Outpatient Department of Subei People's Hospital in Jiangsu Province from January 2022 to December 2023,and fluorescence quantitative polymerase chain reaction (PCR) was used to detect MP-DNA in samples to analyze the detection of MP . A self-made questionnaire was used to collect information on children's hand hygiene, family dietary habits, indoor air conditioning usage, and outdoor exercise. Binary logistic regression was used to analyze the influencing factors of Mycoplasma pneumoniae infection in children. Results The overall infection rate of Mycoplasma pneumoniae in resident children aged 0-14 in Yangzhou from 2022 to 2023 was 32.04%（6 857/21 403）. There was an age difference in the positive rate of Mycoplasma pneumoniae in children, with a higher incidence in the 7-14 years old ( P < 0.001) . There were differences in the infection rate of Mycoplasma pneumoniae in children with different BMI, geographical location, exercise intensity , frequency of using air conditioning ventilation mode, frequency of washing hands before and after meals, frequency of daily drinks、sweets or snacks, and frequency of brushing teeth per day ( P < 0.05 ) .The logistic regression results showed that age between 1-3 years old , BMI ≥ 24 , and never washing hands before and after meals were independent influencing factors for Mycoplasma pneumoniae infection in children ; monthly cumulative precipitation , PM_2.5 , and O₃ increase the risk of Mycoplasma pneumoniae infection in children , while PM10 reduces the risk of Mycoplasma pneumoniae infection in children. Conclusion The positive rate of Mycoplasma pneumoniae in 7-14 year old children in Yangzhou is relatively high. BMI, never washing hands before and after meals, and meteorological factors are closely related to Mycoplasma pneumoniae infection.
