Objective To analyze the prevalence and influencing factors of dyslipidemia among permanent residents in Longquanyi district of Chengdu for prevention and control of dyslipidemia. Methods Permanent residents in Longquanyi district were selected as research objects by convenient sampling method between November 2021 and February 2022. The dyslipidemia rate in the population was analyzed, and the influencing factors of dyslipidemia were analyzed by univariate and multivariate logistic regression. Results A total of 11 408 permanent residents were included. Among them, 3650 people had dyslipidemia, with a prevalence rate of 32.00% (3650/11408). The prevalence rates of high total cholesterol, high triglyceride, high low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol were 19.30% (2 202/11 408), 13.38% (1 526/11 408), 5.05% (576/11 408) and 0.73% (83/11 408), respectively. Multivariate logistic regression analysis showed that female, age≥30 years old, drinking, overweight / obesity, hypertension, diabetes and hyperuricemia were independent risk factors of dyslipidemia among permanent residents (P<0.05). Conclusions The prevalence of dyslipidemia in Longquanyi district is high, mainly with high total cholesterol and high triglyceride. Gender, age, drinking, body mass index, and the levels of blood pressure, blood glucose and blood uric acid are the factors affecting the incidence of dyslipidemia among permanent residents. Early intervention for high-risk groups with dyslipidemia should be adopted to effectively reduce the risk and burden of dyslipidemia.
ObjectiveTo explore the effect of " washing, blowing and plugging” triple therapy on wound treatment after procedure for prolapse and hemorrhoids (PPH) operation.MethodsTwo hundreds and four patients with moderate to severe hemorrhoids treated by PPH from June 2017 to September 2018 in the Fifth Hospital of Zhangjiakou City of Hebei province were selected as study subjects and divided into two groups according to the random number table, the control group received saline fumigation followed by sitz bath and conventional wound dressing change on the second day after operation, the observation group were treated with " washing, blowing and plugging” triple therapy and routine wound dressing change on the 2nd day after operation. The clinical efficacy, wound pain, wound exudation, skin margin edema, hemorrhage, granulation tissue filling time and complete wound healing time were compared between the two groups.ResultsThere was no significant difference in the effective rate between the observation group and the control group in degree Ⅱ hemorrhoids (P>0.05), while the effective rates of patients with degree Ⅲ and Ⅳ hemorrhoids were higher than those of the control group (P<0.05). The visual analogue scale (VAS), wound exudation, skin margin edema and hemorrhage scores of the two groups decreased gradually with time (P<0.05), meanwhile, the scores of VAS, wound exudation, skin margin edema and hemorrhage at each time point in the observation group were lower than those in the control group (P<0.05). The granulation tissue filling time and complete wound healing time in the observation group were shorter than those in the control group (P<0.05).ConclusionsAfter PPH operation, the " washing, blowing and plugging” triple therapy has definite clinical effect, can significantly improve wound pain, wound exudation, skin margin edema and hemorrhage, and effectively shorten the wound healing time.
Objective To analyze the benign-malignant outcomes of pulmonary nodules in surgical patients and their influencing factors, and provide evidence and ideas for optimizing and improving the integrated management model of pulmonary nodules. Methods From October to December 2023, a convenience sampling method was used to select patients who underwent lung surgery at West China Hospital, Sichuan University between July 2022 and June 2023 for this study. The malignancy rate of postoperative pathological results of pulmonary nodules and its influencing factors were analyzed using univariate analysis and multiple logistic regression. Results A total of 4600 surgical patients with pulmonary nodules were included, with a malignancy rate of 88.65% (4078/4600) and a benign rate of 11.35% (522/4600). Univariate analysis showed significant differences in malignancy rates among different genders, ages, methods of pulmonary nodule detection, and smoking histories (P<0.05); however, no significant difference was found regarding place of birth or family history of lung cancer (P>0.05). Multiple logistic regression analysis indicated that females [odds ratio (OR)=1.533, 95% confidence interval (CI) (1.271, 1.850)], older age groups [61-75 vs. ≤30 years: OR=1.640, 95%CI (1.021, 2.634); >75 vs. ≤30 years: OR=2.690, 95%CI (1.062, 6.814)], and pulmonary nodules detected during physical examinations [OR=1.286, 95%CI (1.064, 1.554)] were high-risk factors for malignancy, with statistical significance (P<0.05). Conclusion In the integrated management of pulmonary nodules, it is crucial not to overlook females or older patients, as they may be more significant influencing factors than smoking; furthermore, lung examinations are effective means of early detection of malignant lung tumors and are worth promoting and popularizing.
Objective Endoplasmic reticulum stress (ERS) mediated apoptosis is one of the eukaryotic cellularapoptotic pathways, to investigate the potential role of ERS during myocardium apoptosis in rats with severe burninjury. Methods Sixty-four 7-week-old male Wistar rats, weighing 200-220 g, were randomly divided into 2 groups. Thirtypercentage of total body surface area full-thickness thermal injury was produced in 32 rats of burn group, while sham burn wasproduced in 32 rats of control group. The heart tissues were harvested from 8 rats in each group at 1, 4, 7, and 14 days after burnto observe the changes of myocardium ultrastructure with transmission electron microscope (TEM). Myocardium apoptosis wasdetected with TUNEL assay. The expressions of glucose regulated protein 78 (GRP 78), C/EBP-homologous protein (CHOP),and cleaved Caspase 12 in different pathways of ERS were analysed with Western blot. Results All rats survived during theexperiment. Apoptotic changes of cardiomyocytes were observed in burn group, and the apoptosis index in burn group wassignificantly higher than that in control group at each time point (P lt; 0.05), and it reached peak at 7 days after burn injury(P lt; 0.05). The expressions of myocardial GRP 78, CHOP, and cleaved Caspase 12 showed persistent elevation in burn group.The expressions of GRP 78 and cleaved Caspase 12 in burn group were significantly higher than those in control group at eachtime point (P lt; 0.05), while the expression of CHOP was higher than that in control group at the other time points (P lt; 0.05)except 1st day after burn injury. Conclusion ERS and CHOP, Caspase 12 mediated apoptotic pathway are activated inmyocardium after severe burn injury, and this may be one pathway of myocardium apoptosis.
ObjectiveTo systematically review the prevalence of osteoarthritis in Chinese aged 40 and above from January 2000 to December 2019.MethodsPubMed, ScienceDirect, Wiley Online Library, The Cochrane Library, CBM, VIP, CNKI and WanFang Data databases were electronically searched to collect cross-sectional studies on osteoarthritis in Chinese aged 40 and above from January 1st, 2000 to December 31st, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using R 3.5.2 software.ResultsA total of 29 cross-sectional studies with a total sample of 60 711 cases and 19 707 patients were included. The results of meta-analysis showed that, the crude prevalence of osteoarthritis in Chinese aged 40 and over was 38.46% (95%CI 24.31% to 46.22%). Subgroup analysis results showed that the prevalence of lumbar osteoarthritis was the highest (24.79%, 95%CI 13.28% to 27.37%), followed by knee osteoarthritis prevalence (20.50%, 95%CI 14.51% to 27.23%) which increased with age. The prevalence of knee osteoarthritis in females (25.14%, 95%CI 19.54% to 31.19%) was higher than that in males (18.99%, 95%CI 13.86% to 24.71%). The prevalence of knee and lumbar osteoarthritis in rural areas was higher than that in urban areas. The prevalence of knee osteoarthritis in western China (23.59%, 95%CI 18.34% to 30.35%) was higher than that in eastern China (18.36%, 95%CI 12.43% to 27.92%) and central China (15.54%, 95%CI 11.22% to 21.53%). The prevalence of lumbar osteoarthritis in western China (31.17%, 95%CI 19.21% to 50.60%) was higher than that in eastern China (24.38%, 95%CI 16.26% to 36.54%). The incidence of cervical osteoarthritis in the eastern China (20.49%, 95%CI 13.90% to 30.21%) was higher than that in the western China (12.32% 95%CI 8.09% to 18.75%). The prevalence of hand osteoarthritis in western China (6.85%, 95%CI 2.71% to 8.13%) was higher than that in eastern China (2.7%, 95%CI 1.33% to 5.48%).ConclusionsCurrent evidence shows that the prevalence of osteoarthritis in Chinese aged 40 and above is high, and the prevalence of lumbar osteoarthritis is the highest, and the prevalence in western China is higher than that in eastern and central China, followed by knee osteoarthritis, in which the prevalence in females, rural areas, and western China is high. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusion.
Objective To construct an information hospital service system and discuss the application effect of information construction in the hospital service center. Methods Patients admitted to West China Hospital of Sichuan University between June 2022 and January 2023 were selected. We innovatively practiced intelligent safety gate, self-appointment admission registration, pre-hospital examination and advance migration, pre-hospital health education, an age-appropriate transformation of information service, and other information service measures to investigate the medical experience of patients, and compared patients’ satisfaction with medical treatment under four admission management methods (Huayitong APP, WeChat, self-service machine, and manual management). Results A total of 1452 patients were surveyed. The overall satisfaction score for medical treatment of patients was (4.98±0.04) points. Among them, Huayitong APP was (4.99±0.03) points, WeChat was (4.98±0.13) points, self-service machine was (4.97±0.05) points, and manual treatment was (4.92±0.11) points. There was a statistically significant difference between groups in overall satisfaction with different admission procedures (F=68.582, P<0.001). Since the information construction of the hospital admission service center was carried out, the average time of admission was (12.4±2.3) minutes, and 89.4% (1 298/1 452) of patients thought the time of admission was ideal. Conclusions The information construction of a hospital admission service center can effectively improve patients’ medical experience and enhance patient satisfaction. In the future, it is necessary to explore the influencing factors of patients’ satisfaction with information construction, and constantly improve and upgrade the information construction of hospital admission service centers.
ObjectiveTo investigate the regulatory effect of long chain non-coding RNA (lncRNA) metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) adsorbing microRNA-124 (miR-124) on osteogenic differentiation of mesenchymal stem cells (MSCs).MethodsC3H10T1/2 cells derived from mouse embryos were cultured in vitro, then randomly divided into control group (group A), lncRNA MALAT1 no-load plasmid group (group B), lncRNA MALAT1 overexpression plasmid group (group C), lncRNA MALAT1 small interfering RNA (siRNA) group (group D), and lncRNA MALAT1 siRNA negative control group (group E). The cells were transfected into plasmids and siRNA, then induced to differentiate into osteoblasts. Alkaline phosphatase (ALP) and alizarin red staining were used to detect the osteogenic differentiation of cells in each group, real-time fluorescence quantitative (qRT-PCR) analysis was used to detect the expressions of lncRNA MALAT, miR-124, and osteogenesis-related genes such as Runt-related transcription factor 2 (Runx2), osteopontin (OPN), and osteocalcin (OCN) in each group. Double luciferase reporter gene was used to detect the targeting regulation of lncRNA MALAT1 to miR-124.ResultsThe relative contents of ALP positive cells, mineralized nodule, and the relative mRNA expressions of lncRNA MALAT1, Runx2, OPN, and OCN in group C were significantly higher than those in other groups (P<0.05), while in group D significantly lower than in other groups (P<0.05); the relative expression of miR-124 in group C was significantly lower than that in other groups(P<0.05), while in group D significantly higher than in other groups (P<0.05). There was no significant difference in these indexes between groups A, B, and E (P>0.05). The results of double luciferase reporter gene assay showed that lncRNA MALAT1 targeting down-regulated the expression of miR-124.ConclusionLncRNA MALAT1 can targeting down-regulate the expression of miR-124 and promote the osteogenic differentiation of MSCs.
Unilateral absence of a pulmonary artery (UAPA) is a rare congenital malformation resulting from the failed development or premature involution of the sixth aortic arch during embryogenesis, leading to a failure to establish a connection with the main pulmonary artery. Currently, there is a notable lack of consensus regarding the surgical management of UAPA in China. Drawing upon the latest clinical research, this consensus aims to summarize surgical approaches and techniques to improve the clinical management of UAPA patients and serve as a scientific reference for physicians specializing in pediatric cardiology and structural heart disease. This consensus aims to promote the standardization of UAPA diagnosis and treatment, thereby facilitating improved patient outcomes and long-term management, and stimulating the continuous development and innovation of surgical treatment for this condition in China.
ObjectiveTo summarize the possible roles and relevant mechanisms of solute carrier family 3 member A2 (SLC3A2) gene in hepatocellular carcinoma (HCC), and explore its clinical application prospects and value in the diagnosis, treatment, and prognosis of patients with HCC. MethodThe literature on reseaches of the SLC3A2 gene and its association with HCC both domestically and internationally in recent years was reviewed and summarized. ResultsNotably, the SLC3A2 exhibited obviously elevated expression in the HCC tissue as compared with the normal liver tissue. It mainly affected the disease progression of HCC by regulating the intracellular and extracellular amino acids transport, inhibiting the ferroptosis of cells, activating the mechanistic target of rapamycin complex signaling pathways and integrin signaling pathway, and played an important role in the diagnosis, treatment, and prognosis of patients with HCC. ConclusionFrom the results of literature review collected, SLC3A2 might be closely associated with the migration, invasion, proliferation, and apoptosis of HCC cell, and it is expected to serve as an indicator for evaluating survival and prognosis of patients with HCC, and become one of the effective treatment targets for HCC in future.
ObjectiveTo evaluate the early- and mid-term outcomes of surgical repair of persistent truncus arteriosus in children in a single institution of China.MethodsThe clinical data of 27 consecutive patients with persistent truncus arteriosus undergoing surgical repair in Guangzhou Women and Children’s Medical Center from November 2009 to May 2018 were retrospectively reviewed. There were 14 males and 13 females. Median age was 3.0 months (range: 13 days -11 years), of whom 10 (37.0%) were older than 6 months. ResultsThere were three early deaths with a mortality of 11.1%. The main complications included VSD partial repair in 2 patients, complete atrioventricular block in one patient. The mean follow-up time was 24.5±19.3 months (range: 1–76 months). There were three late deaths, and two patients lost follow. Echocardiology showed seven patients of right heart outflow tract obstruction, including three in pulmonary artery trunk, and four of pulmonary artery branches. One patient showed moderate aortic valve regurgitation. None required re-intervention during the follow-up. Survival estimates for the entire cohort following surgery were both 76.1% (95%CI 59.2% to 92.9%) at 1 year and 5 years.ConclusionThe surgical repair of persistent truncus arteriosus (PTA) remains challenges. The early- and mid-term outcomes of surgical repair of persistent truncus arteriosus are acceptable. For older children with severe pulmonary artery hypertension and/or trunk valve regurgitation, the risk of death is still higher. Some children have the higher risk of late right heart obstructive lesions.
