Vitiligo is a chronic and refractory pigmentary loss skin disease with a complex pathogenesis. Traditional Chinese medicine（TCM） offers advantages in treating vitiligo， such as multi-component and multi-target effects， delivering definite clinical efficacy. This article summarizes the action mechanisms of TCM monomer components and compound formulations in the treatment of vitiligo. It is found that pinostrobin， tribuloside and Erzhi pills can activate the cyclic adenosine monophosphate/protein kinase A （cAMP/PKA） signaling pathway； cannabidiol and tanshinone Ⅱ A can activate the p38 mitogen-activated protein kinase（p38 MAPK）signaling pathway； Ginkgo biloba extract EGb761 and astragaloside Ⅳ can activate the aryl hydrocarbon receptor（AhR） signaling pathway； escin and psoralen derivative BSP-1 can activate the Wnt/β-catenin signaling pathway； apigenin and Baiban granules can activate the nuclear factor erythroid 2-related factor 2/heme oxygenase-1（Nrf2/HO-1） signaling pathway； hyperoside and kaempferol can activate the phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt） signaling pathway； Ruyi heibai powder can activate the programmed death-1/programmed death-ligand 1（PD-1/PD-L1） signaling pathway； Compound honghua buji granules and demethylzeylasteral can inhibit the Janus kinase/signal transducer and activator of transcription （JAK/STAT） signaling pathway. These mechanisms promote melanin production and deposition， reduce oxidative stress， inhibit the destruction of melanocytes by autoimmunity， and reduce melanocyte apoptosis， thereby exerting therapeutic effects on vitiligo.

Objective: To conduct a scoping review on the types, construction methods and predictive performance of health literacy prediction models based on machine learning methods, so as to provide the reference for the improvement and application of such models. Methods: Publications on health literacy prediction models conducted using machine learning methods were retrieved from CNKI, Wanfang Data, VIP, PubMed and Web of Science from inception to May 1, 2024. The quality of literature was assessed using the Prediction Model Risk of Bias ASsessment Tool. Basic characteristics, modeling methods, data sources, missing value handling, predictors and predictive performance were reviewed. Results: A total of 524 publications were retrieved, and 22 publications between 2007 and 2024 were finally enrolled. Totally 48 health literacy prediction models were involved, and 25 had a high risk of bias (52.08%), with major issues focusing on missing value handling, predictor selection and model evaluation methods. Modeling methods included regression models, tree-based machine learning methods, support vector machines and neural network models. Predictors primarily encompassed factors at four aspects: individual, interpersonal, organizational and society/policy aspects, with age, educational level, economic status, health status and internet use appearing frequently. Internal validation was conducted in 14 publications, and external validation was conducted in 4 publications. Forty-two models reported the areas under the receiver operating characteristic curve, which ranged from 0.52 to 0.983, indicating good discrimination. Conclusion Health literacy prediction models based on machine learning methods perform well, but have deficiencies in risk of bias, data processing and validation.

Objective:To analyze the clinical characteristics of children with head and neck rhabdomyosarcoma (RMS) and to summarize the mid-long term efficacy of Beijing Children′s Hospital Rhabdomyosarcoma 2006 (BCH-RMS-2006) regimen and China Children′s Cancer Group Rhabdomyosarcoma 2016 (CCCG-RMS-2016) regimen.Methods:A retrospective cohort study. Clinical data of 137 children with newly diagnosed head and neck RMS at Beijing Children′s Hospital, Capital Medical University from March 2013 to December 2021 were collected. Clinical characteristic of patients at disease onset and the therapeutic effects of patients treated with the BCH-RMS-2006 and CCCG-RMS-2016 regimens were compared. The treatments and outcomes of patients with recurrence were also summarized. Survival analysis was performed by Kaplan-Meier method, and Log-Rank test was used for comparison of survival rates between groups.Results:Among 137 patients, there were 80 males (58.4%) and 57 females (41.6%), the age of disease onset was 59 (34, 97) months. The primary site in the orbital, non-orbital non-parameningeal, and parameningeal area were 10 (7.3%), 47 (34.3%), and 80 (58.4%), respectively. Of all patients, 32 cases (23.4%) were treated with the BCH-RMS-2006 regimen and 105 (76.6%) cases were treated with the CCCG-RMS-2016 regimen. The follow-up time for the whole patients was 46 (20, 72) months, and the 5-year progression free survival (PFS) and overall survival (OS) rates for the whole children were (60.4±4.4)% and (69.3±4.0)%, respectively. The 5-year OS rate was higher in the CCCG-RMS-2016 group than in BCH-RMS-2006 group ((73.0±4.5)% vs. (56.6±4.4)%, χ2=4.57, P=0.029). For the parameningeal group, the 5-year OS rate was higher in the CCCG-RMS-2016 group (61 cases) than in BCH-RMS-2006 group (19 cases) ((57.3±7.6)% vs. (32.7±11.8)%, χ2=4.64, P=0.031). For the group with meningeal invasion risk factors, the 5-year OS rate was higher in the CCCG-RMS-2016 group (54 cases) than in BCH-RMS-2006 group (15 cases) ((57.7±7.7)% vs. (30.0±12.3)%, χ2=4.76, P=0.029). Among the 10 cases of orbital RMS, there was no recurrence. In the non-orbital non-parameningeal RMS group (47 cases), there were 13 (27.6%) recurrences, after re-treatment, 7 cases survived. In the parameningeal RMS group (80 cases), there were 40 (50.0%) recurrences, with only 7 cases surviving after re-treatment. Conclusions:The overall prognosis for patients with orbital and non-orbital non-parameningeal RMS is good. However, children with parameningeal RMS have a high recurrence rate, and the effectiveness of re-treatment after recurrence is poor. Compared with the BCH-RMS-2006 regimen, the CCCG-RMS-2016 regimen can improve the treatment efficacy of RMS in the meningeal region.

ObjectiveTo investigate the distribution of traditional Chinese medicine （TCM） syndrome elements in type 2 diabetes mellitus （T2DM） patients based on maximum body mass index （maxBMI） and explore their association with complication risks. MethodsA retrospective cross-sectional study was used to collect clinical data from hospitalized T2DM patients， extracting age， gender， smoking history， alcohol consumption history， duration of disease， HbA1c level， complications， and TCM syndromes， and extracting the syndrome elements of disease location and disease nature based on their TCM syndromes. MaxBMI was calculated by telephone survey of patients' self-reported maximum body weight； patients with maxBMI ≥24 kg/m² were classified into spleen-heat syndrome group， and those with maxBMI ＜24 kg/m² were classified into consumptive-heat syndrome group. The distribution of TCM syndrome types and syndrome elements of patients in the two groups were analysed. Then the propensity score matching method was used to balance the baseline characteristics between the two groups and compare the differences in the distribution of syndrome types and syndrome elements and the risk of macrovascular and microvascular complications between the two groups. ResultsAmong the 1178 T2DM patients， syndrome elements in spleen-heat patients （1034 cases） were primarily located in the spleen （351 cases， 33.95%）， liver （240 cases， 23.21%）， and stomach （139 cases， 13.44%）， while in consumptive-heat patients （144 cases）， they were concentrated in the spleen （57 cases， 39.58%）， liver （34 cases， 23.61%）， and kidneys （17 cases， 11.81%）； regarding syndrome elements of disease nature， spleen-heat patients were predominantly characterized by qi deficiency （481 cases， 46.52%）， phlegm （353 cases， 22.73%）， and dampness （241 cases， 23.31%）， whereas consumptive-heat patients showed more qi deficiency （84 cases， 58.33%） and yin deficiency （44 cases， 30.56%）. After propensity score matching， 132 cases were included in each group， and no statistically significant differences were observed in the distribution of syndrome elements of disease location between the two groups （P＞0.05）， but the phlegm element was significantly more prevalent in spleen-heat patients than in consumptive-heat patients （P = 0.006）. Regarding the risk of complications， spleen-heat patients had a significantly higher risk of developing macrovascular complications compared to consumptive-heat patients （OR=2.04， P=0.010）， while no significant differences were found between groups in the occurrence of microvascular complications （P＞0.05）. ConclusionThe spleen-heat T2DM patients show a more frequent syndrome element of disease nature of phlegm， and a higher risk of developing macrovascular complications compared to consumptive-heat patients.

Teaching clinics represent a unique form of outpatient training of resident physicians and serve as a crucial instrument and core component of standardized training of general practice residents. This article reviews the common model and innovations of teaching clinics of general practice in China, and analyzes their reported effectiveness in enhancing the capabilities of consultation of resident physicians, the teaching capabilities of general practice trainers, as well as satisfaction levels of involved participants. It outlines the challenges encountered in implementing teaching clinics, including inadequate teaching facilities and equipment, incomplete incentive system for teaching, difficulties in patient recruitment, and weaknesses in the teaching capabilities of trainers. To address these challenges, this article proposes corresponding strategies based on realistic needs, including the improvement of facilities and equipment in teaching clinics, the establishment of incentive systems for teaching clinics, the expansion of patient recruitment channels for teaching clinics, and the enhancement of training for trainers' teaching capabilities. This is envisaged to provide both theoretical bases and practical guidance for the effective execution and standardized development of teaching clinics in general practice residency training bases.

Objective:To evaluate the efficacy and safety of triamcinolone acetonide-saline submucosal injection for prevention of esophageal stricture after endoscopic submucosal dissection (ESD) for extensive superficial esophageal neoplasms.Methods:A total of 75 patients who underwent ESD for superficial esophageal neoplasms involving larger than 2/3 of the esophageal circumference at the Department of Gastroenterology, Northern Jiangsu People's Hospital from January 2018 to December 2020 were enrolled. Patients were randomly assigned to triamcinolone acetonide-saline submucosal injection group (group A, n=25), triamcinolone acetonide injections immediately after ESD group (group B, n=25) and the control group undergoing only ESD (group C, n=25). Serial gastroscopy was performed to assess wound healing and esophageal stricture. Endoscopic balloon dilatation (EBD) was performed when patients experienced esophageal stricture. The completion of ESD, time of operation, the amount of triamcinolone acetonide, the incidences of esophageal stricture and the time of EBD treatment of the three groups were compared. Results:All ESD procedures were successfully performed without complications such as intraoperative perforation, massive bleeding or postoperative delayed perforation. The operation time of group A, B and C were 72.87±12.99 min, 94.15±14.22 min and 74.08±11.86 min, respectively, with significant difference ( F=20.925, P<0.001). In pairwise comparison the above indicator in group A and group C was significantly shorter than that of group B (LSD- t=5.759, P<0.001; LSD- t=5.432, P<0.001), but there was no difference between group A and group C (LSD- t=0.327, P=0.745). There was no significant difference in the amount of triamcinolone acetonide between group A and group B (125±15 mg VS 133±19 mg, t=1.673, P=0.101). The rates of wound healing under endoscopy after 1 month of group A, B and C were 76% (19/25), 84% (21/25), and 76% (19/25), respectively, with no significant difference ( χ2=0.636, P=0.728). The esophageal stricture rates were 52% (13/25) in both group A and B, and 84% (21/25) in group C, with significant difference among the three groups ( χ2=7.295, P=0.026), and group A and B showed a significantly lower stricture rate than that of group C ( P=0.015; P=0.015). The median time of EBD treatment of group A, B and C were 4 (range 0 to 9), 5 (range 0 to 13) and 9 (range 0 to 16), respectively, with significant difference ( H=17.58, P<0.001). In pairwise comparison the above indicator in group A and B was significantly less than that of group C ( H=23.96, P<0.001; H=19.00, P=0.002), but there was no significant difference between group A and group B ( H=4.96, P=0.407). Esophageal stricture was observed in all patients with circumferential mucosa resected in the three groups. But the times of EBD treatment were 6.90±1.10 in group A, 10.13±2.42 in group B and 15.29±0.76 in group C with significant difference ( F=57.754, P<0.001). In pairwise comparison the above indicator in group A was less than that in group B (LSD- t=4.294, P<0.001) and this indicator in group B was less than that in group C (LSD- t=6.294, P<0.001). Median EBD times in patients with non-circumferential mucosal defects in the three groups were 0 (range 0 to 9), 0 (range 0 to 6) and 8 (range 0 to10), respectively, with significant difference ( H=19.72, P<0.001). In pairwise comparison, the EBD time in group A and B was less than that in group C ( H=17.93, P<0.001; H=16.62, P<0.001), but there was no statistical difference between group A and B ( H=1.31, P=0.779). Conclusion:Triamcinolone acetonide-saline submucosal injection ESD can safely and effectively prevent esophageal stricture after ESD for large-area superficial esophageal neoplasms, reduce the operation time and time of EBD treatment in patients with circumferential mucosa defect compared with local injections of triamcinolone acetonide after ESD.

Objective:To explore the impact of the hospital health literacy environment on patients′ postoperative pain self-management behaviors, aiming to provide insights for hospitals to implement the Comprehensive Pain Management Pilot Work Program in hospitals and to promote self-health management among patients with other diseases or symptoms. Methods:From November to December 2023, a convenience sampling method was used to select postoperative patients from three grade A tertiary general hospitals in Zhejiang Province for an on-site questionnaire survey. The Chinese version of brief health literacy screen (BHLS), short-form health literacy environment scale (SF-HLES) and postoperative pain self-management behavior questionnaire (PPSMB) were used as survey tools to investigate the health literacy level of patients, the health literacy environment of the hospital, and the postoperative pain management behaviors of patients. Two-way ANOVA was used to compare the impact of different dimensions of the hospital health literacy environment on postoperative pain management behaviors among patients with different levels of health literacy. Multiple linear regression analysis was used to explore the relationship between the hospital health literacy environment, individual health literacy, and patients′ postoperative pain self-management behaviors, and to discuss the impact of individual health literacy on patients′ postoperative pain self-management behaviors under different hospital health literacy environments.Results:341 valid questionnaires were collected. The average score of the hospitals′ SF-HLES was (73.62±19.54) points. The average score of the patients′ BHLS was (9.65±2.88) points. The average score of the patients′ PPSMB was (25.99±6.35) points. Two-way ANOVA results showed that the interaction between individual health literacy and the clinical dimension ( F=5.463, P=0.020) and structural dimension ( F=6.470, P=0.011) of the hospital health literacy environment had a statistically significant impact on patients′ postoperative pain self-management behaviors, while the interaction with the interpersonal dimension ( F=0, P=0.984) had no statistically significant impact on pain self-management behaviors. Simple effect analysis indicated that only in the high health literacy environment of the clinical and structural dimensions did the difference in pain self-management behaviors between patients with good health literacy and those with limited health literacy had statistical significance ( P<0.001). Multiple linear regression analysis results showed that for each 1-point increase in the patients′ BHLS score, their PPSMB score increased by 3.74 points ( β1=0.832, P<0.001); for each 1-point increase in the hospital′s SF-HLES score, the patients′ PPSMB score could increase by 0.198 points ( β2=0.610, P<0.001). In a low health literacy environment, individual health literacy did not affect pain self-management behaviors ( P>0.05); however, in a high health literacy environment, for each 1-point increase in the patients′ BHLS score, their PPSMB score correspondingly increased by 4.037 points ( β4=0.317, P<0.001). Conclusions:The positive impact of individual health literacy on pain self-management is contingent upon a high-quality hospital health literacy environment. This suggests that optimizing the hospital health literacy environment is a necessary precondition for implementing the relevant content of the Comprehensive Pain Management Pilot Work Program and can provide a reference for promote self-health management among patients with pain and other diseases or symptoms.

Objective To observe the impact of ultrasonic image quality on the consistency of artificial intelligence(Al)assisted diagnosis system and manual measurements of biological indicators of developmental dysplasia of hip(DDH).Methods Hip ultrasonic data of 75 DDH and 345 non-DDH children were retrospectively analyzed,and the quality of ultrasonic images were subjectively scored.An evaluation model of ultrasonic image quality was constructed based on 140 ultrasonic images acquired from 140 cases(group A,containing 25 DDH and 115 non-DDH)using entropy weighting method,the weight of anatomic structures and impact factors related to DDH were obtained.The comprehensive image quality scores of other ultrasonic images acquired from 280 cases(group B,including 50 DDH and 230 non-DDH)were calculated,and the images in group B were classified into grade A,B and C in descending order.The consistency of AI and manual measurements of DDH biological indicators in group B was assessed.Results The weight of each anatomic structure and impact factors of DDH obtained with the model were as follows:The lower edge of iliac branch＞ilium＞glenoid labrum＞bony margin＞femoral head＞motion artifacts.In group B,grade A was observed in 67(9 DDH and 58 non-DDH),grade B was found in 160(26 DDH and 134 non-DDH),while grade C was noticed in 53(15 DDH and 38 non DDH)images.Except for β,femoral head coverage(FHC)and femoral head length diameter,the consistencies between AI and manual measurements of other indicators of DDH were grade A＞B＞C.In group B,AI and manual measurements were more consistent in DDH than in non-DDH cases.Conclusion Ultrasonic image quality affected the consistency between AI and manual measurements of biological indicators of DDH.When image quality was not good enough,further attention should be paid to measurement of FHC and sizes of femoral head.
