Objective:To investigate the status of self-management and family support among elderly diabetic patients in community.Methods:Eight elderly patients with type 2 diabetes were interviewed in Xietu Community Health Service Center in Shanghai by semi-structured interviews from March 1st to March 15th, 2022. The interview outline focused on the impact of the disease on the patients' daily life, the status of disease self-management, and the support provided by their family. The contents of interviews were analyzed and extracted by Colaizz 7-step analysis method.Results:Of the 8 interviewees, there were 2 males and 6 females, aged (75.25±3.01)years old, with a disease course of (17.50±8.50)years. The interviews showed that there were three themes in the area of family support: difficulties in disease management (in terms of diet, exercise, medication, disease surveillance, health knowledge and quitting unhealthy habits), helpfulness of family support in management of above behaviors, differences between family support and support from others (including eating habits, information sharing, emotional support, patient trust, and continuity of support).Conclusions:The elderly diabetic patients in the community have some awareness of health management, but there is still much room for improvement. The supervision and support from family members can help patients improve their self-management and quality of life.

Objective:To comprehensively search the relevant literature on prone position-cardiopulmonary resuscitation (PP-CPR) in adults at home and abroad, analyze the content, summarize the evidence, and provide reference for clinical health care professionals.Methods:Systematic search of CNKI, China Biomedical Literature Service System (SinoMed), Wanfang Data, VIP database, PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochran Library, Web of Science, Scopus literature database and other Chinese and English databases was conducted. The search period was from inception to June 15 in 2024. The contents of PP-CPR from randomized controlled trial (RCT), non-RCT (prospective or retrospective), cohort studies and case reports were extracted and systematically analyzed. The search results were standardized by the method of scoping review.Results:A total of 523 articles were obtained through preliminary search, and 14 references and gray literature were retrieved, totaling 537 articles. After strict screening by two researchers, a total of 26 literatures were included, 3 were non-RCT and 23 were case reports, involving 12 countries, including 3 in Chinese, 19 in English, 2 in French, 1 in German, and 1 in Korean. Three non-RCT demonstrated that compared with standard cardiopulmonary resuscitation (CPR), PP-CPR could produce higher pressure, and provide good respiratory and circulatory support. A total of 25 adult patients were included in the 23 case reports, of which 17 reported total recovery time and 13 reported PP-CPR time ≤ 5 minutes, all of which recovered spontaneous circulation, indicating the effectiveness of PP-CPR technology. In terms of final outcome, 4 patients (16.0%) died and 21 patients (84.0%) survived, indicating that PP-CPR technology could provide timely blood circulation and improve clinical outcomes for prone cardiac arrest patients. Among the 11 patients who reported complications after resuscitation, no neurological damage was found in the short-term outcomes, indicating that PP-CPR technology had a certain level of safety.Conclusions:PP-CPR can provide timely blood circulation for patients with cardiac arrest who are unable to lie supine quickly, and win "golden time" for defibrillation and further treatment. In clinical practice, medical staff need to evaluate the emergency environment, the number of rescuers and the specific condition of the patient, and implement first aid as soon as possible, so as to reduce the time of no blood flow in the vital organs of patients with cardiac arrest in prone position, and improve the clinical prognosis.

Objective To construct a deep learning-based artificial intelligence model to automatically quantify left ventricular ejection fraction (LVEF) using static views of echocardiography. Methods The study included data of 1, 902 adults with left ventricular multi-slice echocardiographic views at end-systole and end-diastole. The collected dataset was divided into development set (1, 610 cases, with 1, 252 cases for model training and 358 cases for parameter adjustment), internal test set (177 cases for internal validation), and external test set (115 cases for external validation and generalization testing). The model achieved left ventricular segmentation and automatic quantification of LVEF through precise identification of the left ventricular endocardial boundary and inspection of key points. The Dice coefficient was employed to evaluate the performance of the left ventricular segmentation model, while the Pearson correlation coefficient and the intraclass correlation coefficient were used to assess the correlation and consistency between the automatically measured LVEF and the reference standard. Results The left ventricular segmentation model performed well, with Dice coefficients ≥ 0.90 for both the internal and external independent test sets; the agreement between the automatically measured LVEF and the cardiologists' manual measurements was moderate, with Pearson correlation coefficients ranging from 0.46 to 0.71 and intragroup correlation analysis agreements from 0.39 to 0.57 for the internal test set; and Pearson correlation coefficients for the independent external test set were 0.26 to 0.54 and intra-group correlation analysis agreement of 0.23 to 0.50. Conclusion In this study, a left ventricular segmentation model with better performance is constructed, and initial application of the model for automatic quantification of LVEF for two-dimensional echocardiography has general performance, which requires further optimisation of the algorithm to improve the model generalisation.

Objective:To evaluate the effect of family intervention on self-management and glycaemic control in patients with type 2 diabetes mellitus (T2DM).Methods:Clinical interventional trials on the family intervention for T2DM patients were searched in PubMed, Medline, Embase, Cochrance libraries, the CNKI, and the Wan Fang Database from January 2016 to June 2023. Literature was screened according to the inclusion and exclusion criteria. Self-management behavior, BMI and glycated haemoglobin of T2DM patients were used as outcome indicators. Meta-analysis and mapping were performed using Review Manager 5.3 software. A systematic review of the literature on indicators of self-management behavior measured using other instruments except Summary of Diabetes Self-Care Activities.Results:A total of 1 342 relevant papers were retrieved and 13 papers were included in the analysis, involving 1 454 patients, 740 in the intervention group and 714 in the control group. Meta-analysis showed that the inclusion of home-based intervention helped adult T2DM patients to improve self-management ( WMD=5.03, 95% CI:4.43-5.63, P<0.001) and reduce glycated hemoglobin compared with the hospital-patient dichotomous model ( WMD=-0.77, 95% CI:-1.32--0.21, P=0.007), but the effect on BMI was unclear ( WMD=-0.38, 95% CI:-1.04-0.28, P=0.25). The results of the systematic review supported that home-based intervention improving self-management behaviors of adult T2DM patients. Conclusion:Family intervention can improve self-management behaviors and reduce glycated haemoglobin levels in adults T2DM patients.

It was a retrospective study. The patients with type 2 diabetes mellitus (T2DM) who underwent renal biopsy in the Department of Nephrology, the First Affiliated Hospital of Xi'an Jiaotong University from 2015 to 2021 were enrolled to analyze the pathological and clinical manifestations of kidney. There were 483 patients enrolled, including 136 patients who had no history of diabetes mellitus, newly diagnosed as T2DM according to an oral glucose tolerance test. The age was (52.80±13.13) years old. There were 337 males (69.77%). Based on the renal biopsy, the patients were classified as diabetic kidney disease (DKD, 22.15%, 107/483), DKD+non-diabetic kidney disease (NDKD)(6.63%, 32/483), and NDKD (71.22%, 344/483). Membranous nephropathy was the most common pathology in patients with NDKD (40.41%, 139/344) and DKD+NDKD (34.38%, 11/32). In the 136 newly diagnosed T2DM patients, there were 3 patients (2.21%) with DKD, 2 patients (1.47%) with DKD+NDKD, and 131 patients with NDKD (96.32%). The proportions of DKD in patients with diabetes history ≤3 months, 3-12 months, 1-5 years, 5-10 years and ≥10 years were 10.53% (6/57), 25.00% (16/64), 26.53% (26/98), 41.56% (32/77) and 47.06% (24/51), respectively. The proportions of DKD+NDKD in patients with diabetes history ≤3 months, 3-12 months, 1-5 years, 5-10 years and ≥10 years were 3.51% (2/57), 3.13% (2/64), 10.20% (10/98), 9.09% (7/77) and 17.65% (9/51), respectively. Multivariate logistic regression analysis results showed that, the duration of diabetes history ( OR=1.130, 95% CI 1.057-1.208, P<0.001), diabetes retinopathy ( OR=12.185, 95% CI 5.331-27.849, P<0.001), urinary red blood cell count ( OR=0.987, 95% CI 0.974-0.999, P=0.039), glycosylated hemoglobin ( OR=1.482, 95% CI 1.119-1.961, P=0.006) as well as hemoglobin ( OR=0.973, 95% CI 0.957-0.990, P=0.001) were independently correlated with DKD. The proportions of DKD and DKD+NDKD increase with the prolongation of diabetes history. Membranous nephropathy is the most common pathology in NDKD and DKD+NDKD patients. Even in patients newly diagnosed with T2DM, it is necessary to screen for DKD. The duration of diabetes history, diabetes retinopathy, urinary red blood cell count, glycosylated hemoglobin and hemoglobin may be used to identify DKD from NDKD.

Objective:To screen high-risk population of chronic obstructive pulmonary disease (COPD) and to analyze the risk factors in Haicang District of Xiamen City.Methods:A questionnaire survey was conducted from February 2023 to May 2023 among residents who visited or underwent physical examinations at five community health service centers in Haicang District of Xiamen City selected by cluster sampling method. The self-designed general information questionnaire, COPD population screening questionnaire (COPD-PS) and COPD screening questionnaires (COPD-SQ) were applied in the survey. Individuals with COPD-PS scale>5 or COPD-SQ scale>16 were defined as COPD high-risk group. The association of COPD risk with gender, age, smoking, family history of COPD, history of tuberculosis, history of COVID-19 infection, and using coal/woodstove for cooking or heating was analyzed with chi-square test and binary logistic regression analysis.Results:A total of 4 260 questionnaires were distributed and 4 221 valid questionnaires were collected with a recovery rate of 99.6%. Among all respondents there were 1 904 males (45.11%) and 2 317 females (54.89%); and 217 individuals aged 40-<50 (5.14%), 434 aged 50-<60 (10.28%), 2 194 aged 60-<70 (51.98%), 1 302 aged 70-<80 (30.85%) and 74 aged≥80 (1.76%). The results showed that there were 269 respondents (6.4%) scored≥5 on the COPD-PS scale, 534 residents (12.7%) scored≥16 on the COPD-SQ scale, 646 (15.3%) scored≥5 on the COPD-PS scale or≥16 on the COPD-SQ scale. Male gender ( OR=2.592, 95% CI:2.135-3.146), second-hand smoke exposure ( OR=3.763, 95% CI:2.944-4.810), frequently catching cold before the age of 14 ( OR=3.804, 95% CI:2.927-4.944), history of tuberculosis ( OR=2.575, 95% CI:1.224-5.418), hypertension ( OR=1.547, 95% CI:1.277-1.875), and diabetes ( OR=1.791, 95% CI:1.027-3.121) were independently associated with the high-risk of COPD, while the history of COVID-19 ( OR=0.583, 95% CI:0.476-0.714) was a protective factor for COPD risk. Conclusion:Males, exposure to second-hand smoke, frequently catching cold before the age of 14, history of tuberculosis, hypertension, and diabetes will increase the risk of COPD, while the history of COVID-19 is a protective factor.

With the increasing prevalence of atrial fibrillation (AF), the incidence of its complications, such as ischemic stroke and thromboembolism is also increasing. According to the two-way referral system proposed by health authorities, AF management should be carried out mainly in primary care settings;and studies show that general practitioners play an indispensable role in AF management. At present,however,the inappropriate anticoagulation,AF complications and risk awareness are three major problems in the primary care of AF management in China. This article reviews the status quo and future prospect of AF management in primary care to provide suggestions for better management of AF in primary care level.

Ferroptosis is a newly discovered non-apoptotic regulatory form of cell death characterized by accumulation of iron-dependent lipid peroxides and reactive oxygen species （ROS）. p53 is a tumor suppressor gene that can induce cell cycle arrest， apoptosis， autophagy， and senescence to maintain genomic stability by mediating transcriptional regulation of a variety of key cellular genes. Recent studies have found that p53 can also regulate ferroptosis bidirectionally by multiple cellular responses including iron metabolism， polyunsaturated fatty acid （PUFAs） metabolism， amino acid metabolism and nicotinamide adenine dinucleotide phosphate （NADPH）-mediated metabolisms， and participate in the pathological progression of diseases such as tumors， nervous system diseases， cardiovascular diseases， liver disease， and kidney disease. This paper provided a systematic review of the mechanism of p53-mediated ferroptosis in the outcome of related diseases and its influencing factors. And the research advance in the mechanisms of targeted regulation of p53-mediated ferroptosis in the prevention and treatment of cancer， stroke， acute ischemic cardiomyopathy， chronic heart failure， atherosclerosis， ulcerative colitis， and adjuvant arthritis by traditional Chinese medicine was also elaborated. This paper was expected to provide new ideas for the prevention and treatment against related diseases.

Objective:To investigate the effect of obstruction on the prognosis and possible mechanisms in colorectal cancer patients.Methods:Among 1574 cases of colorectal cancer who were treated in Beijing Friendship Hospital, Capital Medical University from January 2003 to December. 2014, 194 cases had preoperative intestinal obstruction. Firstly, described the clinical characteristics of 194 patients with obstruction, then COX multivariate regression analysis was performed on the 1574 colorectal cancer cohort to confirm whether the preoperative obstruction was independent predictor for the overall survival. Finally, propensity score matching method was used to match obstruction and non-obstruction cases, then compared overall survival difference.Results:In 194 cases of obstructive colorectal cancer, 60.3% and 37.1% of the tumors were located in the left and right respectively. The 55.7% of the patients had tumors larger than 5 cm in diameter, the median survival time was 39.7 months (95% CI: 28.3-60.4). Multivariate COX analysis, after adjusted for related confounding factors, found that preoperative obstruction is still an independent risk factor for poor prognosis ( HR=1.41, 95% CI: 1.01-1.97). After propensity score matching, 140 and 560 patients were included in the obstructive group and the non-obstructive group. The two groups were more balanced in most baseline characteristics. The median survival time of the two groups was 42.4 and 116.3 months ( P<0.001), the overall survival of obstructive patients was significantly worse than that of non-obstructive patients. Conclusions:Preoperative obstruction is an independent risk factor for poor prognosis of colorectal cancer. This may be due to the difficulty of surgery and low radical cure rate for obstructive colorectal cancer.
