To analyze the current state and issues of ideological education for graduate students of general practice, from April 10 to Dec 19, 2024, a literature review was conducted on publications from Jan 1, 2001, to Dec 19, 2024, in the CNKI, Wanfang, and VIP databases to identify research entry points. Purposive sampling was used to select postgraduate students majoring in general practice at Guangzhou Medical University and their corresponding faculty as the study participants. A semi-structured in-depth interview method was employed to investigate the current state of ideological and political education. Faculty evaluations of students and their recommendations for ideological and political education were also considered. Thematic framework analysis was applied to the interview data for categorization, integration, and theme extraction. The literature review revealed that enhancing professional identity can strengthen career commitment, leading to the design of an ideological and political education interview outline focused on professional belief and professional identity. The study included 13 general practice postgraduates (mean age: 24.5±1.4 years), of whom 8 were directional students and 5 were non-directional students. Additionally, 7 general practice faculty members were included (mean age: 41.3±5.4 years), with an average of 16.3±5.6 years of experience in general practice education. Five themes were extracted from the interviews: the necessity of ideological and political education, the relationship between professional belief and its educational effects, the intrinsic motivation of ideological beliefs, the influence of external factors on beliefs, and effective approaches to ideological and political education. The study also identified current issues in ideological and political education for general practice postgraduates, including inadequate career planning guidance, reluctance to work in underdeveloped areas, over-reliance on the role modeling of faculty mentors, lack of systematic courses and frameworks for ideological and political education, and limited opportunities for team projects and communication platforms. The current state of ideological and political education for general practice postgraduates reveals deficiencies in career planning support, systematic course construction, practical opportunities, and communication platforms. Education methods remain overly simplistic and are significantly influenced by external factors, underscoring the need for optimization and enhancement.

ABSTRACT OBJECTIVE To explore the pharmacological mechanism of trace elements in preterm low birth weight infants through network pharmacology. METHODS Targets associated with trace elements were obtained from Drugbank database and TTD database. Genes related to preterm low birth weight infants were collected from GeneCards database and DisGeNET database. Two groups of data were intersected to get mapping targets. Protein-protein interaction network of mapping targets were constructed by STRING database. Candidate targets were screened by Cytoscape 3.6.1 and ranked to obtain key targets. The major trace elements were defined by establishing network of “trace elements-candidate targets”. Kyoto Encyclopedia of Genes and Genomes(KEGG) and Gene Ontology(GO) term enrichment analysis was performed via g:Profiler software to predict the molecular mechanisms and related pathways of trace elements on preterm low birth weight infants. RESULTS A sum of 211 targets of trace elements in preterm low birth weight infants were screened, including 26 candidate targets and three key targets: albumin(ALB), glyceraldehyde-3-phosphate dehydrogenase(GAPDH) and fibronectin 1(FN1). The major trace elements were copper(Cu) and zinc(Zn), regulating 22 and 19 targets respectively. KEGG pathway enrichment analysis predicted that three major pathways were complement and coagulation cascades, cholesterol metabolism as well as lipid and atherosclerosis. CONCLUSION The major trace elements Cu and Zn may cause neuronal damage and reduce the risk of oxidative stress-related diseases in premature infants through the regulation of GAPDH, ceruloplasmin(CP), superoxide dismutase 1(SOD1), etc. The appropriate levels of Cu and Zn for preterm infants may regulate cholesterol metabolism and other signaling pathways and therefore reduce the risk of cardiovascular diseases in premature infants and adult. Further investigation of the pharmacological mechanism of trace elements in preterm infants is necessary to provide a more sufficient theoretical basis for the good growth and development of preterm infants.

The incidence and mortality rates of cholangiocarcinoma (CCA) are increasing constantly, and it is of great importance to explore new therapeutic targets. Ferroptosis, a unique pattern of cell death caused by iron-dependent cellular oxidative injury, is closely associated with iron metabolism and oxidative stress imbalance in cancer and has become a research hotspot in the field of tumor. This article introduces the mechanism of ferroptosis and the research advances in ferroptosis involved in the development and progression of CCA, and it is pointed out that the regulatory mechanism of ferroptosis has an important clinical value in the malignant progression of CCA.

Objective To investigate the current situation of animal injury among children in Chongqing, and to provide a scientific basis for relevant departments to formulate and implement strategies and measures to prevent and control animal injury to children. Methods According to the method of multi-stage stratified cluster sampling, 14,056 children in grades 4-12 in four districts of Chongqing were selected as the investigation subjects, and the occurrence of animal injuries in the past 6 months was investigated. Results The incidence of animal injury among school children in Chongqing was 0.35% and the incidence of person-time was 0.36%. The incidence rate in males (0.48%) was higher than that in females (0.31%). The incidence rate in urban children (0.43%) was higher than that in rural children (0.30%). The incidence of animal injury was the lowest in nuclear families (0.25%), and the highest in single-parent families (0.82%). There were statistically significant differences in the incidence of animal injuries in children among different fathers' occupational types, family types and parents' parenting styles (P<0.05).  The main place of child animal injury was home (57.14%). Recreational activities were the main cause of animal injury (51.02%). The main injuries were lower limbs (42.86%), upper limbs (24.49%) and head (10.20%). Conclusion The prevention and control of children's animal injury in Chongqing should focus on boys and families. It is suggested to take targeted and comprehensive interventions to prevent animal injuries in children.

Objective:To investigate high resolution CT (HRCT) manifestations and clinical features of patients infected with the novel coronavirus B.1.617.2 variant.Methods:A total of 125 patients with the novel coronavirus B.1.617.2 variant in Guangzhou Eighth People′s Hospital from May 21 to June 9, 2021 was enrolled. There were 52 males and 73 females, aged from 1 to 92 years old with a median age of 47 year. The clinical features and HRCT characteristics were analyzed retrospectively.Results:Of the 125 patients, the main clinical manifestations were fever in 54 patients, cough in 50 patients, pharyngeal discomfort in 39 patients, and diarrhea in 5 patients. HRCT showed pneumonia in 96 cases, which predominantly had ground-glass opacities in 92 cases, ground-glass opacities combined with local consolidation in 22 cases, consolidation in 11 cases, intralobular interstitial thickening in 51 cases, centrilobular structural thickening in 23 cases, and cord-like lesions in 33 cases. One patient had pleural effusion, and no enlarged lymph nodes were observed in all patients. The lesions were distributed in the subpleural and/or peripheral lung in 96 cases and along the bronchovascular bundle (middle and inner zone) in 24 cases. The time interval from onset to positive HRCT was 3 (1, 4) days in 96 patients with pneumonia on HRCT. HRCT showed absorption after the imaging findings reaching the peak in 20 patients, and the time interval between the first positive HRCT findings and the peak imaging was 6 (3, 7) days in these 20 patients.Conclusions:The novel coronavirus B.1.617.2 variant has a strong infectivity, short viral latency. Lung injury is decreaseel. People of all ages are susceptible and the diseasemay have rapid pnegression. HRCT mainly shows ground glass opacities, which are more common in subpleural and/or in the lung periphery, with interlobular thickening.

In recent years, with the changes in living standards and dietary structure, the incidence of non-alcoholic fatty liver disease has been increasing year by year in China, and the incidence rate in the general population is as high as 29.81%. An increasingly epidemiological evidence suggests that non-alcoholic fatty liver disease has become one of the causes of increasing liver cirrhosis and liver cancer. However, its etiology and pathogenesis are complex and have not yet been fully elucidated. Therefore, establishing an appropriate non-alcoholic fatty liver disease animal models for pre-clinical research is essential to elucidate its pathogenesis. This article summarizes the latest research progress of non-alcoholic fatty liver disease animal models, which are common at home and abroad in recent years.

Objective:To investigate the effects of multiple trace elements in neonatal parenteral nutrition (PN) on the stability of fat emulsion, and to assess the changes of stability indexes after filtration.Methods:With the standard body weight of 1.5 kg, seven groups of neonatal PN solutions with different concentrations of multiple trace elements were designed, including blank group (without multiple trace elements), normal dose group (1 ml/kg, i.e., 0.75 ml per 100 ml PN) and five experimental groups (i.e., 1.5 ml, 3 ml, 4.5 ml, 6 ml, and 7.5 ml per 100 ml PN respectively). Macroscopic observation was performed 0 h and 24 h after preparation. The mean droplet diameter (MDD) of lipid emulsion was determined with dynamic light scattering before and after filtration. The percentage of fat residing in globules larger than 5 μm (PFAT5) and the globule size distribution before and after filtration were determined with light blockage method.Results:Macroscopic examination of the 7 groups of PN solutions identified neither changes in color nor stratification within 24 hours after solution preparation. Within 24 hours after solution preparation, the MDDs of all PN solutions before filtration were between (338.67±6.11) nm and (370.00±15.13) nm, and the PFAT5 values before filtration ranged from (32.00±1.00) ×10 -3% to (85.67±6.81) ×10 -3%. The MDDs of all PN solutions after filtration were between (310.67±8.62) nm and (362.33±19.86) nm, and the PFAT5 values after filtration ranged from (4.67±1.15) ×10 -3% to (17.33±0.58) ×10 -3%. The concentration of multiple trace elements was positively correlated with PFAT5 ( P<0.05). There was statistically significant difference in PFAT5 values at 0 h and 24 h after preparation ( P=0.004). The difference of PFAT5 values before and after filtration was also statistically significant ( P=0.000). Conclusions:Within 24 hours after solution preparation at room temperature, the appearance of neonatal PN solutions with different concentrations of trace elements supplementation was unchanged, and the MDDs of fat emulsions were all within the safe range. However, when the concentration of monovalent cations (Na +, K +) was 38.9 mmol/L, the concentration of divalent cation (Ca 2+) was 5 mmol/L, and the concentration of trace elements (Zn 2+, Cu 2+, Mn 2+, and Se 4+) was higher than 0.063 mmol/L, the PFAT5 value was higher than 0.05%. In this case, filtration with a 1.2 μm filter was necessary, which could significantly reduce the PFAT5 value and the globule size distribution, and improve the safety and standardization of the clinical application of PN solutions. It is suggested that the neonatal PN solutions supplemented with multiple trace elements injection (I) may be administered through a terminal filter.
