ObjectiveTo systematically evaluate the methodological quality and measurement properties of traditional Chinese medicine （TCM） syndrome efficacy evaluation scales， and to provide evidence-based references for selecting high-quality assessment tools in TCM clinical practice. MethodsChina National Knowledge Infrastructure （CNKI）， Wanfang Data， VIP Database， Chinese Biomedical Literature Database （CBM）， PubMed， the Cochrane Library， Embase， and Web of Science were searched from inception to April 2， 2025， for studies evaluating the measurement properties of TCM syndrome efficacy evaluation scales. Data were extracted， and the methodological quality and measurement properties of the included scales were assessed according to the consensus-based standards for the selection of health measurement instruments （COSMIN）. Recommendation levels were formulated based on the grading of evidence. ResultsA total of 46 studies were included， involving 22 generic syndrome efficacy evaluation scales and 24 disease-specific syndrome efficacy evaluation scales. None of the scales reported cross-cultural validity or measurement error. According to the recommendation grades， 2 scales met Grade A recommendations and are suggested for clinical use； 38 scales were classified as Grade B， indicating potential applicability but requiring further validation； and 6 scales were classified as Grade C， suggesting the need for further refinement. ConclusionExisting TCM syndrome efficacy evaluation scales exhibit substantial variability in methodological quality， incomplete reporting of measurement properties， and insufficient attention to scale revision. Future efforts should emphasize standardized design in the development of TCM syndrome scales， strengthen validation procedures for key measurement properties， and prioritize dynamic revision of scales， thereby providing high-quality tools to support the precise evaluation of syndrome efficacy.

One good practice statement and six expert consensus statements were proposed for plasma and platelet transfusions in critically ill children following severe trauma, traumatic brain injury, and/or intracranial hemorrhage. This article introduces the specific methods and basis for the formation of recommendations in this part of the guide.

Hepatic fibrosis is a complex dynamic process caused by multiple chronic pathogenic factors， characterized by excessive accumulation of liver extracellular matrix and abnormal liver structure and function. If anti-fibrotic treatment is not performed in time， it can progress to liver cirrhosis and even liver cancer. Hepatic fibrosis has a complex pathogenesis， and previous studies mainly focused on the activation of hepatic stellate cells. Recent studies have shown that myeloid cells have the potential of multi-directional differentiation and can also participate in the development and progression of hepatic fibrosis. This article systematically reviews the role and regulatory mechanism of myeloid cells in hepatic fibrosis， in order to provide a reference for clinical diagnosis and targeted therapy.

A 51-year-old male presented with nasal obstruction, followed by progressive hearing loss and blurred vision. Imaging identified space-occupying lesions in the paranasal sinuses, orbits, and paraspinal regions, while laboratory tests confirmed positive anti-proteinase 3 anti-neutrophil cytoplasmic antibody(PR3- ANCA) immunoglobulin G (IgG)and markedly elevated serum IgG4. Despite treatment with corticosteroids, immunosuppressants, and radiotherapy, the patient exhibited steroid dependency with relentless disease progression. Following multidisciplinary consultation, a diagnosis of inflammatory myofibroblastic tumor (IMT) coexisting with ANCA- associated vasculitis (AAV) was favored, though IgG4-related disease remained a critical differential. Ultimately, profound immunosuppression precipitated a severe herpesvirus infection, leading to disseminated intravascular coagulation and multiple organ dysfunction syndrome. This case underscores the rarity and diagnostic complexity of concurrent IMT and AAV, highlights the therapeutic dilemma of balancing primary disease control against fatal opportunistic infections, and emphasizes the critical role of multidisciplinary collaboration in the diagnosis and treatment of complex diseases.

Objective To analyze the epidemiological characteristics and spatial-temporal clustering trend of scarlet fever in Nantong from 2009 to 2023, and to provide a scientific basis for scarlet fever prevention and control. Methods The incidence data of scarlet fever in Nantong from 2009 to 2023 were analyzed. Descriptive analysis, seasonal index method and Joinpoint 5.2.0 software were used to analyze epidemiological characteristics. Spatial-temporal clustering was assessed with SaTScan 10.2.5 software. Results The average annual incidence of scarlet fever in Nantong from 2009 to 2023 was 6.54/100 000. The overall morbidity rate of scarlet fever in Nantong had an increasing trend from 2009 to 2019 with an average annual percentage change of 14.55% (t=3.36，P<0.05). The cases mainly occurred during late spring to early summer and late autumn to early winter. Students, preschool children and scattered children were the main scarlet fever population. The average annual incidence of males was significantly higher than that of females (χ²=7.00, P<0.05). Rugao City, Chongchuan District and Tongzhou District were identified as high-incidence areas, accounting for 76.51% of all reported cases. Spatial-temporal scan analysis indicated that Rugao City and Chongchuan District were primary cluster areas, spanning from 2015 to 2021 (RR=3.77, LLR=1 308.07, P<0.05). Conclusion The number of reported cases of scarlet fever in Nantong City from 2009 to 2023 shows epidemic and spatial clustering, mainly concentrated in the central urban area and adjacent counties (cities). It is necessary to strengthen health education and disease surveillance in high-incidence areas, as well as in key institutions and key populations before epidemic peaks.

ObjectiveTo investigate growth hormone secretagogue receptor （GHSR） rs2922126 gene polymorphisms and their association with genetic susceptibility to nonalcoholic fatty liver disease （NAFLD） in the Chinese Han population in Qingdao， China， and to provide a basis for diagnosis and treatment. MethodsA total of 220 patients who were admitted to Qingdao Municipal Hospital from June 2022 to June 2023 and were diagnosed with NAFLD based on radiological examination were enrolled as NAFLD group， and 167 healthy individuals during the same period of time were enrolled as control group. Fasting blood samples were collected from all subjects， and related biochemical parameters were measured. Whole blood DNA was extracted， and polymerase chain reaction and MALDI-TOF mass spectrometer were used for genotyping. The chi-square test was used for comparison of categorical data between groups， and the independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between groups. The binary logistic regression analysis was used to investigate the risk of NAFLD. ResultsCompared with the control group， the NAFLD group had significantly higher age， body mass index （BMI）， fasting plasma glucose， triglyceride， gamma-glutamyl transpeptidase， alkaline phosphatase， alanine aminotransferase， and aspartate aminotransferase， as well as a significantly lower level of high-density lipoprotein （all P0.05）. The distribution of GHSR rs2922126 genotypes was consistent with the Hardy-Weinberg equilibrium， suggesting population representativeness in the subjects enrolled （NAFLD group： P=0.106； control group： P=0.849）. There was no significant difference in the distribution of AA， TA， and TT genotypes at GHSR rs2922126 locus between the control group and the NAFLD group （P=0.099）， and there was also no significant difference in allele frequency between the two groups （P=0.063）. In the recessive model of A allele， there was a significant difference in the distribution of AA homozygote and TA+TT genotype between the NAFLD group and the control group （P=0.032）. The binary logistic regression analysis showed that in the recessive model of A allele， AA homozygote carriers had an increased risk of NAFLD compared with TA+TT genotype carriers （odds ratio ［OR］=1.712， 95% confidence interval ［CI］： 1.045 — 2.807， P=0.033）. There was still a significant difference after adjustment for sex， age， and BMI （OR=2.156， 95%CI： 1.221 — 3.808， P=0.008）. In the NAFLD group， AA genotype carriers had a significantly higher serum level of total cholesterol （TC） than TT+TA carriers （Z=-1.99，P=0.046）. ConclusionGHSR rs2922126 AA genotype may be associated with the increased risk of NAFLD in the Chinese Han population in Qingdao， and GHSR rs2922126 AA genotype is associated with the increase in TC in NAFLD patients.

Objective To investigate the mechanism of action of the nuclear factor erythroid 2-related factor 2(Nrf2)/solute carrier family 7 member 11(SLC7A11)/glutathione peroxidase 4(GPX4)signaling pathway in non-alcoholic fatty liver disease(NAFLD),and to explore the mechanism of Gegen QinLian Decoction for the treatment of NAFLD,using in vivo and in vitro experiments.Methods Rats were fed with high-fat chow for 24 weeks to induce NAFLD,and were then divided randomly into normal(C),model(M),high-,medium-,and low-dose Gegen QinLian Decoction(GGQLT-H,GGQLT-M,GGQLT-L),and metformin(Met)groups.From week 25 onwards,the rats were administered the corresponding drugs by gavage for 2 weeks according to the grouping,until sampling.Levels of the oxidative stress markers malondialdehyde(MDA)and glutathione(GSH)in the liver tissues were measured in each group using biochemical kits and ferrous iron(Fe2+)in rat liver tissues was detected using a Fe2+kit.Nrf2,heme oxygenase-1(HO-1),SLC7A11,glutathione synthetase(GSS),GPX4,and acyl coenzyme A synthetase 4(ACSL4)mRNA levels in rat liver tissues were measured by reverse transcription quantitative polymerase chain reaction.For cellular experiments lipid acc umulation was induced in HepG2 hepatocellular carcinoma cells using 1 mmol/L free fatty acid,to mimic the NAFLD in vitro model.Different concentrations of Gegen QinLian Decoction and metformin-containing serum were added for treatment.Lipid accumulation was detected in the cells in each group by Oil red O staining.The MDA and GSH contents of HepG2 cells in the different groups were determined using appropriate kits,and the ferrous contents were detected using a cell-specific ferrous kit.Expression levels of Nrf2,HO-1,SLC7A11,GSS,GPX4,and ACSL4 mRNA was detected in each group of cells using reverse transcription quantitative polymerase chain reaction.Results In the animal experiments,MDA and Fe2+liver levels were significantly higher in the M group than in the C group,while GSH levels were significantly lower(P＜0.01).GGQLT-H,GGQLT-M and Met groups showed significantly reduced MDA and Fe2+and elevated GSH levels compared with the M group(P＜0.01,P＜0.05).High-and medium-dose Gegen QinLian Decoction and metformin increased Nrf2,HO-1,GSS,and GPX4 mRNA and decreased ACSL4 mRNA expression levels(P＜0.01,P＜0.05).In cellular experiments,lipid droplets were significantly increased in the HepG2 cell M group compared with those in the C group,and lipid droplets were significantly reduced by Gegen QinLian Decoction and metformin.MDA and Fe2+levels were significantly increased and GSH levels were significantly decreased in the HepG2 M group compared with the levels in the C group(P＜0.01),while all doses of Gegen QinLian Decoction and metformin significantly decreased MDA and Fe2+levels(P＜0.01)and increased the GSH content(P＜0.01,P＜0.05).Nrf2,GSS,GPX4,and SLC7A11 mRNA expression levels in the GGQLT-H group,Nrf2,HO-1,and SLC7A11 in the GGQLT-L group,HO-1,SLC7A11,and GSS in the GGQLT-M group,and GSS,Nrf2,and HO-1 in the Met group were all significantly increased compared with the findings in the M group(P＜0.01,P＜0.05).ACSL4 mRNA expression levels were significantly decreased in the GGQLT-M and GGQLT-L groups and the Met group(P＜0.01,P＜0.05).Conclusions Gegen QinLian Decoction can improve NAFLD by inhibiting ferroptosis,and its mechanism may he related to regulation of the Nrf2/SLC7A 11/GPX4 signaling pathway.

Objective:To explore the application effectiveness of the "summarize-narrow-analyze-probe-plan-select" (SNAPPS) teaching method in early clinical training of pediatrics, compare this method with traditional teaching approach, and provide new insights for curriculum instruction.Methods:A prospective randomized controlled trial was conducted with 100 students enrolled in the Introduction to Pediatrics course at Chongqing Medical University. Participants were divided into an experimental group (SNAPPS method) and a control group (traditional lecture-based method). Both groups studied five core chapters and were assessed using mini-clinical evaluation exercise with standardized patient models. Teaching experience and satisfaction were evaluated through questionnaires and interviews, followed by quantitative and qualitative analyses. Statistical analysis was performed using GraphPad Prism 8. Continuous variables were expressed as mean ± standard deviation and independent samples t-test was used for between-group comparisons. Ordinal data were expressed as median (interquartile range) and Mann-Whitney U test was used for between-group comparisons. Results:The experimental group outperformed the control group in medical history collection [(9.20±0.70) vs. (8.50±0.90), t=4.34, P<0.001], clinical judgment [(9.30±0.60) vs. (8.60±0.80), t=3.89, P=0.003], and overall performance [(9.00±0.90) vs. (8.30±1.00), t=3.51, P=0.002]. However, there were no significant differences between the two groups in physical examination, communication skills, professional behavior, organization and efficiency, or health education and counseling. Self-assessment results indicated significant improvements in the experimental group in case summarization, clinical reasoning, diagnostic accuracy, treatment planning ability, and self-directed learning ability ( P<0.05). Regarding teaching satisfaction, evaluations from both students and instructors were higher in the experimental group than in the control group ( P<0.05), indicating a preference for the SNAPPS teaching model. Conclusions:The SNAPPS teaching method demonstrates significant advantages in cultivating clinical thinking, self-directed learning, and treatment planning abilities, effectively enhancing teaching satisfaction and providing an effective teaching model for early clinical training of medical students.

Objective:To investigate the application effect of BOPPPS+team-based learning (TBL) based on the concept of outcome-based education (OBE) in the teaching of infectious rash and fever illnesses in children.Methods:A total of 199 undergraduate students of the class 2019 in the five-year program of Department of Pediatrics in Chongqing Medical University were selected as subjects, and they were divided into experimental group with 99 students and control group with 100 students using a random number table. The students in the experimental group received BOPPPS+TBL teaching based on the OBE concept, while those in the control group received traditional teaching. After the end of the curriculum, scores were compared between the two groups, and a questionnaire survey was conducted for self-evaluation of teaching and learning effectiveness and the acceptance of teaching models. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:The experimental group had a significantly higher score of the course than the control group [(88.08±5.31) vs. (85.62±8.44), P=0.014]. The questionnaire survey showed that compared with the control group, the experimental group had significantly higher scores of the self-evaluation of teaching effectiveness [(4.40±0.75) vs. (3.36±1.13), P<0.001] and learning effectiveness [(4.31±0.84) vs. (3.35±1.19), P<0.001]. In the experimental group, 96.96% (96/99) of the students believed that BOPPPS+TBL teaching based on the OBE concept could help students to master and understand the knowledge points, and 93.93% (93/99) of the students were willing to use this teaching model in future learning. Conclusions:BOPPPS+TBL teaching based on the OBE concept can help to achieve teaching objectives and significantly improve student satisfaction and learning outcomes.

Objective: To evaluate the intervention efficacy of integrated group social skills training on social ability in school age patients with high functioning ASD, so as to provide a reference for improving social skills in children with high functioning ASD. Methods: From January 2021 to December 2023, 62 children aged 7-12 with high functioning ASD who visited the Children s Psychiatry Outpatient Department of the Affiliated Kangning Hospital of Ningbo University were recruited, and were randomly divided into a training ( n =31) and a control group ( n =31) by a random number table method. The training group received a 20 week structured group social training program (mental interpretation courses and social courses), while the control group received only conventional treatment. Chinese version of Griffith Empathy Measure Parent Ratings (GEM-PR) and Social Response Scale (SRS) were used to assess the symptoms of social deficits before and after treatment. Emotional face recognition tasks and eye movement trajectories were used to test the characteristics of social visual attention in children with ASD. Group comparison was conducted using t-test and Mann-Whitney U test. Results: At baseline, there were no significant differences in GEM-PR score ( t = -1.20 to -0.81), SRS score ( t =-0.36-1.75), emotional face recognition accuracy and reaction time ( t =-0.58-1.85), and eye movement trajectory ( U/t =-1.63-0.29) between the two group ( P >0.05). After intervention, the total GEM-PR score and empathic cognitive factor score of training group [18.00(10.00，24.00)，9.00(8.00，13.00)] were significantly higher than those of the control group [12.00(-1.00，18.00)，2.00(-2.00，7.00)], and the total SRS score and social cognition, social perception, social communication, social motivation (73.23±14.20, 16.16±2.72, 6.58±2.50, 24.29±5.61, 9.52±3.73) were significantly lower than those of the control group (95.26±15.29, 19.90±2.84, 12.58±2.49,31.94±6.38, 13.74±4.81) ( U/t =-2.38, -4.59; -5.88, -5.29, -9.47, -5.01, -3.87, P <0.05). The overall correct rate of emotional face recognition and the correct rate of angry, fearful and neutral faces recognition in the training group [(81.55±6.62)%，(76.86±12.06)%，(79.61±12.42)%，(94.27±6.26)%] were significantly higher than the control group [(70.55±13.82)%，(62.82±18.77)%，(67.18±18.85)%，(79.60±20.05)%], and the average reaction time [(2 226.70±274.43)ms] was lower than the control group [(2 417.27±324.10)ms] (t=4.00, 3.50, 3.07, 3.89, -2.42, P<0.05). The time to first eye gaze [764.74 (748.64, 793.73) ms] in the training group was significantly lower than that in the control group [810.92 (782.86, 877.42) ms], and the proportion of moderatetohigh intensity attention area in the face [(37.37±1.27)%] was significantly higher than that in the control group [(30.34±1.23)%] (U/t=3.44, 8.89, P<0.05). Conclusion Integrated group social training can significantly improve the social communication and empathy ability of high functioning ASD children, increase active attention and recognition ability of faces, and improve mental development of children with ASD.
