Kui was first recorded in The Rites of Zhou and is the earliest domesticated wild vegetable in China. In the Qi Min Yao Shu, Kui was called “the master of all vegetables” and has a long history of application in China. As a medicine, Kuizi was first recorded in Shen Nong’s Herbal Classic, which has a history of more than 2 000 years of medicinal use and a long history of clinical application. By researching the ancient and modern herbal literature, the first herbs texts of Kui were examined, various recorded texts, confused products and the history of the original medicinal use were clarified. It was concluded that the ancient herbal texts recorded the base plant of Kui as Malva verticillata L. belonging to family Malvaceae, which provided scientific basis for the development and utilization of Kui.

ObjectiveTo investigate the incidence and influencing factors of posttraumatic stress disorder （PTSD） three months after a traffic accident， and to explore the role of social support and coping strategies. MethodsA total of 117 individuals exposed to trauma following road traffic accidents were recruited. General demographic and clinical information was collected within one week， and the hamilton anxiety rating scale （HAMA）， the hamilton depression rating scale-24 （HAMD-24）， the social support rating scale （SSRS）， and the simplified coping style questionnaire （SCSQ） were administered. A 3-month follow-up was subsequently conducted， during which PTSD symptoms were assessed using the post-traumatic stress disorder checklist for DSM-5 （PCL-5）. Participants were divided into a PTSD group and a non-PTSD group according to whether PTSD occurred. Between-group comparisons were performed using the Mann-Whitney U non-parametric test or the χ² test， as appropriate. Spearman correlation analysis was used to examine the associations between general characteristics and PCL-5 scores. Binary Logistic regression was applied to identify factors influencing PTSD， and receiver operating characteristic （ROC） curve analysis was conducted to evaluate the diagnostic value of the SCSQ and SSRS. ResultsDuring the 3-month follow-up of the 117 trauma-exposed individuals， 17 cases developed PTSD， with a higher proportion of females （70.59%）. Between-group comparisons showed that， compared with the PTSD group， the non-PTSD group had higher scores for positive coping， objective support， and subjective support （P<0.05）， and lower scores for negative coping， HAMA， HAMD， and PCL-5 （P<0.05）. Correlation analysis indicated that female gender， negative coping， and higher HAMA and HAMD scores were associated with greater PTSD severity. Logistic regression analysis demonstrated that educational level （OR=1.715， 95% CI： 1.020-2.883， P=0.042） and negative coping （OR=1.590， 95% CI： 1.003-2.522， P=0.048） were risk factors for PTSD， whereas objective support （OR=0.646， 95% CI： 0.451-0.925， P=0.017） was a protective factor. The ROC analysis showed that the total SCSQ score and its negative and positive coping dimensions， the total SSRS score and its subjective and objective support dimensions， as well as their combined use， all demonstrated good discriminative ability in distinguishing between the PTSD and non-PTSD groups. ConclusionThe results suggest that individuals who are female， with higher HAMA and HAMD scores after a motor vehicle accident， and those with lower social support and negative coping strategies， should be given particular attention. Early interventions for these individuals may reduce the incidence of PTSD.

Objective:To identify the relevant factors for the first-course remission of acute myeloid leukemia (AML) and to develop a predictive model as well as assess its predictive capability.Methods:Clinical data of 749 patients newly diagnosed with AML admitted to the Department of Hematology, the First Affiliated Hospital, Zhejiang University, School of Medicine from January 1, 2019, to April 30, 2023, were collected and randomly divided into training and validation sets. Multivariate logistic regression analysis was conducted to determine variables associated with complete remission in the first course of induction therapy, and a predictive model was established based on these variables. The receiver operating characteristic (ROC) curve of the predictive model was plotted, and the area under the curve (AUC) was calculated.Results:The indicators predicting the first remission course included peripheral blood white blood cell count during onset, CBF::MYH11 fusion gene, CEBPA bZIP region mutation, myelodysplastic syndrome-related gene mutation, and induction chemotherapy regimen selection as independent factors for the first remission course. The model’s area under the training and validation curves was 0.738 (95% CI: 0.696-0.780) and 0.726 (95% CI: 0.650-0.801), respectively. The Hosmer-Lemeshow test results yielded P-values of 0.993 and 0.335, respectively. Conclusion:In this study, the developed model demonstrates a strong predictive capability for the efficacy of the first course of patients with AML, providing valuable guidance to clinicians in assessing patient prognosis and selecting appropriate treatment strategies.

Objective:To evaluate the potential value of 18×10 3 translocator protein (TSPO) radioligand ( N, N-diethy1-2-(2-(4-(2- 18F-fluoroethoxy) phenyl)-5, 7-dimethylpyrazolo[1, 5-A]pyrimidin-3-yl)acetamide, 18F-DPA-714) PET compared with conventional MR in the detection of autoimmune encephalitis (AE), the correlation with clinical symptoms, and the monitoring of immunotherapy efficacy in patients with AE. Methods:From December 2021 to June 2024, 45 AE patients (17 males, 28 females, age (38.3±17.0) years) diagnosed at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine and 10 healthy volunteers (7 males, 3 females, age (28.7±5.1) years) were enrolled in this prospective study. All participants underwent baseline 18F-DPA-714 PET/MR scans, and 23 of these AE patients underwent further follow-up 18F-DPA-714 PET/MR scans. 18F-DPA-714 PET positivity was defined as having an uptake intensity threshold higher than the mean SUV ratio (SUVR)+ 2 s of the corresponding brain region in healthy controls. MR positivity was defined as abnormal hyperintensity in a specific brain region or multiple brain regions on the T 2 fluid attenuated inversion recovery (FLAIR). The positive detection rates of 18F-DPA-714 PET and MR was analyzed using McNemar χ2 test, and the differences in the uptake intensity (SUVR) of 18F-DPA-714 between symptomatic and non-symptomatic groups, and between remission and non-remission groups after immunotherapy were compared using independent-sample t test or Wilcoxon rank sum test. Spearman rank correlation analysis was used to analyze the correlation between the changing rate of SUVR and the changing of the modified Rankin Scale (mRS) score before and after treatment. Results:The positive detecting rate of 18F-DPA-714 PET for AE was significantly higher than that of MR (73.3%(33/45) vs 35.6%(16/45); χ2=11.56, P=0.001). The cerebellar SUVR of ataxia patients was significantly higher than that of asymptomatic patients (1.22(1.06, 1.33) vs 1.08(0.99, 1.20); Z=-2.14, P=0.034). Follow-up imaging showed that the SUVR of patients in the remission group after immunotherapy was significantly lower than that in the non-remission group ((-15.19±10.17)% vs (14.26±13.36)%; t=5.81, P<0.001). There was a significant correlation between the changing rate of SUVR and the changing of the mRS score before and after treatment ( rs=0.65, P<0.001). Conclusion:Compared with conventional MR, 18F-DPA-714 PET has a higher positive detecting rate for AE, and has the potential to reflect the clinical symptoms of AE and monitor the efficacy of immunotherapy.

Objective:To explore and demonstrate the effect of general-specialty hierarchical management mode for chronic heart failure (CHF) in community.Methods:This was a single-blind, randomized, controlled study. A total of 530 CHF inpatients who attended Weifang Community Health Service Center (WCHSC) in Pudong New Area from February 2018 to September 2019 were consecutively enrolled. A random number table method was used to divide the patients into the management group ( n=265) and control group ( n=265). The demographic data and past medical history were collected 1 day before enrolment (baseline), and patients were assessed for New York Heart Association (NYHA) cardiac function classification and tested for blood N-terminal B-type natriuretic peptide proteins (NT-proBNP) levels, while Doppler echocardiography was performed to obtain the relevant indexes. The management group used a comprehensive management mode, co-delivered by both WCHSC (offering primary care) and RHSJUSM (offering specialty care) at Renji-Weifang CHF Studio in WCHSC , using the jointly developed CHF hierarchical CHF diagnosis and treatment criteria and referral procedure under the condition of sharing drugs and laboratory test results for CHF. The control group received routine heart failure care. Intergroup comparisons were made on baseline data obtained before follow-up and on NT-proBNP , left ventricular ejection fraction (LVEF), NYHA functional class , re-hospitalization rate and mortality rate at the end of the 6-month follow-up. Results:A total of 506 cases completed the follow-up. There were 253 patients in the management group, aged (68.26±9.41) years, 117 males (46.2%); 253 were in the control group, aged (66.98±9.63) years, 115 males (45.5%). There were no statistically significant differences in age, sex, marital status, education level, and comorbidities between the two groups (all P>0.05). At baseline, the differences in LVEF and NT-proBNP between the two groups were not statistically significant (all P>0.05), and at 6 months of intervention, LVEF, and NT-proBNP had significantly improved in both groups (all P<0.05) . Moreover, LVEF was higher in the management group than in the control group, and NT-proBNP was lower than in the control group (both P<0.01). At baseline, there were 166 cases (65.6%) in the control group with NYHA class Ⅲ/Ⅳ, and 145 cases (57.3%) in the comprehensive management group. There was no statistically significant difference between the two groups ( P>0.05). At 6 months of intervention, the percentage of NYHA class Ⅲ/Ⅳ patients in the comprehensive management group was lower than at baseline ( P<0.01),while that in the control group was higher than at baseline ( P<0.01), and the comprehensive management group was lower than that in the control group ( P<0.01). During the follow-up period, the rehospitalization rate for CHF in the management group was 13.83%(35/253), which was lower than that in the control group, which was 26.88%(68/253) ( P<0.001). Conclusion:The comprehensive management mode of CHF in the community through collaboration between general and specialized departments can significantly improve the management effect, suggesting that this mode is effective and can be promoted.

This consensus was developed by the Orthodontic Society of the Chinese Stomatological Association to provide a systematic, scientific, and practical guideline for informed consent in orthodontic care. Orthodontic treatment is typically lengthy, highly individualized, and involves multiple factors such as growth and development, occlusal function, and facial esthetics. Rapid technological advances and diverse risk profiles make the traditional reliance on orthodontist experience or institutional templates insufficient to ensure patients′ full understanding and autonomous decision-making. To address this, the expert panel conducted extensive reviews of domestic and international guidelines, analyzed representative dispute cases, and performed multicenter patient-clinician surveys. Using a multi-round Delphi method, the group established a standardized informed consent framework covering the initial consultation, treatment, and retention phases. The consensus emphasizes that informed consent is not only a fundamental legal and ethical requirement but also a key step in building trust, improving patient compliance, and enhancing treatment satisfaction. Orthodontists should clearly and comprehensively explain treatment plans, potential risks, uncertainties, and associated costs, while respecting the autonomy of patients or guardians, and maintain continuous communication and dynamic evaluation throughout the treatment process. The release of this consensus provides unified and authoritative guidance for clinical orthodontics, helping to standardize informed consent, enhance its transparency, safeguard patient rights, reduce medical risks, and promote high-quality, sustainable development of orthodontic practice.

Objective:To translate the Triage Risk Screening Tool (TRST) into Chinese and to test its reliability and validity among older patients in the emergency department.Methods:The Brislin translation model was used to translate and back-translate the English version of the TRST. After cultural adaptation and pre-testing, and subsequently, the final Chinese version of the TRST (TRST-C) was formed. Using the convenience sampling method, a questionnaire survey was conducted on 174 elderly patients who visited the emergency department of Nanjing Drum Tower Hospital Affiliated to Medical School of Nanjing University to verify the reliability and validity of the scale.Results:The item-level content validity index and the scale-level average content validity index were 0.89-1.00 and 0.978, respectively. Exploratory factor analysis extracted 2 common factors, and the cumulative variance explanation rate was 63.095%. Using 2 points as the threshold for high risk of adverse outcomes. The sensitivity of TRST-C for 30-day death, emergency department readmission, rehospitalization and composite adverse outcomes were 94.4%, 81.8%, 84.6% and 84.9% respectively, and the negative predictive values were 98.3%, 86.4%, 86.4% and 76.3%, respectively. The Cronbach α coefficient and the Guttman split-half reliability of the TRST-C were 0.639 and 0.669, respectively. The Kappa coefficient was 0.911. Conclusions:The TRST-C has good reliability and validity, which can screen elderly patients of emergency department at risk of adverse outcomes.

Objective:To investigate the role of Gasdermin E (GSDME) -mediated keratinocyte pyroptosis induced by Cutibacterium acnes ( C.acnes) in the pathogenesis of acne. Methods:The human immortalized keratinocyte HaCaT cells were stimulated with heat-inactived C.acnes for 15 minutes to 24 hours, and Western blot analysis was performed to determine the expression of cleaved GSDME (GSDME-NT) in HaCaT cells at different time points. Skin tissue samples were collected from 5 acne patients and 4 healthy controls, who visited the Hospital for Skin Diseases, Chinese Academy of Medical Sciences from January 2 to December 1, 2024; additionally, 3 samples of acne cyst contents and 3 samples of normal follicle contents were collected. Immunohistochemical study and Western blot analysis were conducted to determine GSDME-NT expression in the epidermis. Enzyme-linked immunosorbent assay (ELISA) was performed to detect levels of interleukin (IL) -1β and tumor necrosis factor (TNF) -α in acne cyst or normal follicle contents. GSDME-knockdown HaCaT cells were constructed by transfection with lentivirus carrying GSDME-shRNA, and HaCaT cells transfected with lentivirus carrying the nonsense sequence control (NC) served as controls; ELISA was performed to detect the levels of IL-1β and TNF-α in GSDME-knockdown HaCaT cells after C. acnes stimulation ( C. acnes + GSDME knockdown group) , as well as in the phosphate-buffered saline (PBS) + NC group, C. acnes + NC group, and PBS + GSDME knockdown group. Western blot analysis was conducted to determine the GSDME-NT expression in HaCaT cells pretreated with or without retinol after C. acnes stimulation. Results:The cleavage of GSDME in HaCaT cells began at 1 hour after in vitro C. acnes stimulation, and GSDME-NT could be detected at this time. Compared with the control epidermis, the proportion of GSDME-NT-positive HaCaT cells (9.34% ± 2.92% vs. 3.05% ± 1.14%, t = -3.47, P = 0.026) and GSDME-NT protein expression levels ( t = -3.51, P = 0.025) significantly increased in the lesional epidermis of acne patients. The levels of IL-1β and TNF-α were significantly higher in the acne cyst contents than in the normal follicle contents (IL-1β: 1 337.24 [1 182.32, 2 230.61] pg/ml vs. 0.00 [0.00, 108.21] pg/ml, Z = 1.99, P = 0.046; TNF-α: 811.31 [438.26, 817.73] pg/ml vs. 46.67 [12.41, 53.21] pg/ml, Z = 1.96, P = 0.049) . ELISA showed that the levels of IL-1β and TNF-α were significantly higher in the C. acnes + NC group (12.12 ± 3.07 pg/ml, 26.06 ± 1.57 pg/ml, respectively) than in the PBS + NC group (3.73 ± 2.24 pg/ml, 10.14 ± 0.79 pg/ml, P = 0.003, < 0.001, respectively) ; compared with the C. acnes + NC group, the levels of IL-1β and TNF-α significantly decreased in the C. acnes + GSDME knockdown group (3.38 ± 0.93 pg/ml, 12.67 ± 2.10 pg/ml, P = 0.003, < 0.001, respectively) . The GSDME-NT expression was significantly lower in the retinol + C. acnes group than in the C. acnes group ( P = 0.029) . Conclusion:C. acnes may induce GSDME-mediated pyroptosis in keratinocytes, thereby promoting the release of inflammatory factors and aggravating the inflammatory response in acne, while retinol may be able to inhibit this process.

Objective:To evaluate the association between heatwaves and fall-related mortality.Methods:A total of 61 421 fall-related mortality from 2013 to 2022 in 7 provinces of China were included in a time-stratified case-crossover design, with daily meteorological data derived from the fifth generation European Reanalysis dataset produced by the European Centre for Medium-Range Weather Forecasts. Conditional logistic regression chimeric distributed lag nonlinear model was used to analyze the association between heatwaves and fall-related mortality and stratified analysis was conducted according to gender and age.Results:Heatwaves were associated with an increased risk of fall-related morality. The risk of fall-related mortality during heatwaves was higher than during non-heatwave periods ( OR=1.11, 95% CI: 1.05-1.18). The attributable fraction of fall-related motality due to heatwaves was 10.25% (95% CI: 4.49%-15.36%). For each 1 ℃ increase above the heatwave threshold, the risk of fall-related mortality increased by 34% ( OR=1.34, 95% CI: 1.02-1.76). The effect of heatwave duration on fall-related mortality was not statistically significant. Stratified analyses indicated that women experienced a higher risk of fall-related mortality during heatwaves ( OR=1.13, 95% CI: 1.04-1.22) compared to man ( OR=1.10, 95% CI: 1.04-1.17). Conclusions:Heatwave increases the risk of fall-related mortality, and the intensity of heatwaves modify this risk. Women are vulnerable populations.

Objective:To evaluate the impact of short-term exposure to daytime heatwaves, nighttime heatwaves, and compound heatwaves on the risk of road traffic mortality and calculate the attributable mortality burden.Methods:This study collected road traffic mortality data from the Disease Surveillance System in Guangdong, Hunan, Zhejiang, Yunnan, and Jilin Provinces from 2013 to 2018. A time-stratified case-crossover design was used in this study, with the death date for each case serving as the case day. Control days were selected from the same year, month, and day of the week as the case day. A conditional logistic regression model was employed to estimate the cumulative associations of short-term exposure to daytime heatwaves, nighttime heatwaves, and compound heatwaves on the risk of road traffic mortality (lag 0-1 day) and to calculate the attributable fractions (AF).Results:Compared to non-heatwave days, the excess risk ( ER) of road traffic mortality on daytime heatwave days, nighttime heatwave days, and compound heatwave days was 5.3% (95% CI: 0.5%-10.2%), 4.9% (95% CI: 0.5%-9.4%) and 7.5% (95% CI: 2.3%- 12.9%), with corresponding AF of 5.0% (95% CI: 0.5%-9.3%), 4.7% (95% CI: 0.5%-8.6%), and 6.9% (95% CI: 2.3%-11.4%), respectively. Stratified analysis showed that the risk of traffic mortalities caused by daytime heatwaves was higher in females ( ER=15.7%, 95% CI: 5.8%-26.5%) than in males ( ER=1.8%, 95% CI: -3.6%-7.4%). Elderly individuals over 64 years old ( ER=10.9%, 95% CI: 0.3%- 22.6%) had a higher risk of road traffic mortalities from compound heatwaves than those under 45 years old ( ER=2.6%, 95% CI: -5.4%-11.2%). The risk of road traffic injury mortality from motor vehicle accidents caused by compound heatwaves ( ER=16.6%, 95% CI:2.4%-32.7%) was higher than that from non-motor vehicle accidents ( ER=5.7%, 95% CI:0.1%-11.5%). Conclusions:Short-term exposure to daytime heatwaves, nighttime heatwaves, and compound heatwaves was associated with an increased risk of road traffic mortality, with the strongest association observed for compound heatwaves. The mortality burden attributable to compound heatwaves was higher than that for daytime and nighttime heatwaves. Heatwaves were more significantly associated with road traffic mortality risk among females, elderly individuals over 64 years old, and motor vehicle accidents.
