Narrative medicine focuses on empathy， relevance， and emotion， precisely aligning with the elements of “clown doctor” such as compassion， interaction， and pain relief. From the perspective of narrative medicine， the practice of “clown doctors” not only focuses on the emotional changes of patients but also enhances their sense of belonging by recreating their experiences. The key element for the success of “clown doctors” lies in establishing a multi-dimensional trust relationship among medical workers， patients， colleagues， and society， while ensuring their practice adheres to medical ethics norms. “Clown doctors” should concentrate on dimensions such as concept dissemination， clinical application， social recognition， and ethical practice of narrative medicine. They should also constantly optimize narrative techniques， deepen the understanding of patients’ stories， and intervene in the medical process in a more delicate and comprehensive way， thereby fostering in-depth communication and understanding between doctors and patients.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Clinical trials represent a pivotal stage in the development of pharmaceutical drugs. Nevertheless， given the unique characteristics of traditional Chinese medicine （TCM） and the diagnostic and treatment principle of syndrome differentiation and treatment in TCM， the clinical evaluation techniques and methods that can comprehensively reflect the characteristics of TCM and are tailored to its specificities are still in need of refinement and innovation. This paper systematically summarizes the key techniques and methods for designing and evaluating the clinical research on the treatment of the spleen and stomach diseases with TCM from three aspects including clinical research design， evaluation， and platform construction， compares domestic and international research landscapes， and proposes for future directions. It is suggested that a multidimensional evaluation system integrating modern medicine and TCM theory should be established， and further innovation is needed in TCM research design and methodologies， leveraging intelligent devices and technologies powered by next-generation information technology to transform clinical data into high-quality TCM evidence. Moreover， standardized and shared platforms for TCM clinical data should be accelerated， so as to provide references for the design， implementation， and evaluation of future clinical research on the treatment of the spleen and stomach diseases with TCM.

Symptom and syndrome efficacy evaluation scales are indispensable tools for clinical efficacy assessment in traditional Chinese medicine （TCM）， and hold significant value at all stages of new drug research development for spleen and stomach diseases. These scales can provide scientific basis for clinical positioning， efficacy evaluation， and expansion of indications of new drugs. By analyzing the current hotspots and difficulties in research， this study aims to explore the important significance of these scales in the development of new drugs for spleen and stomach diseases， summarize the domestic research progress， and conduct comparative analyses with international studies. Future development trends are also discussed in order to promote the application of symptom and syndrome efficacy evaluation scales in the development of new drugs for spleen and stomach diseases and to advance the moder-nization process of TCM.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Background: Malignant vasovagal syncope (VVS) is characterized by cardiac arrest lasting more than 3 seconds during a syncope episode or head-up tilt test (HUTT). We aim to conduct a risk assessment for potential malignant VVS before the HUTT by using economic, simple and convenient demographic data, in order to prevent adverse outcomes for pediatric VVS.Purpose: To explore the correlation between demographic factors and pediatric malignant VVS, and verify the value of these factors in early risk assessment for malignant VVS before HUTT, so as to optimize test safety and reduce adverse events. Methods: We conducted a retrospective analysis of the clinical data of 3,734 children who were initially diagnosed with VVS due to unexplained syncope and presyncope. Finally, 122 children who met the diagnostic criteria for malignant VVS were included in the malignant VVS group, and 661 children who did not meet the criteria during the same period were matched as the control group. By analyzing demographic data and other factors, we attempted to clarify the association between these factors and malignant VVS. Results: Linear relationship: age and body mass index (BMI) have independent protective effects on malignant VVS. For every 1-year increase in age and every 1 kg/m2 increase in BMI, the risk of malignant VVS decreases by 12% and 9%, respectively. Nonlinear relationship: When the age is <12.9 years old, for every additional year of age, the risk of malignant VVS decreases by 20%. For ages 12.9 years and above, the efficacy is not significant. There is no significant nonlinear relationship between BMI and malignant VVS. Conclusion Age and BMI are independent protective factors for pediatric malignant VVS. Before the age of 12.9 years, the incidence of malignant VVS gradually decreases with the increase in age, and thereafter there is no significant impact.

OBJECTIVE To investigate the molecular mechanism of Tiaozhong huashi decoction in improving gastroesophageal reflux disease （GERD） by regulating endoplasmic reticulum autophagy in rat esophageal interstitial cells of Cajal （ICC） through p62 signaling pathway.METHODS After establishing a rat GERD model via the weak acid intragastric administration and irregular diet， the rats were randomly divided into model group， western medicine group [1.56 mg/（kg·d） of mosapride， 3.125 mg/（kg·d） of lansoprazole] and low-， medium- and high-dose Tiaozhong huashi decoction [4.713， 9.425， 18.85 g/（kg·d）] groups. A blank group was also set up， with 8 rats in each group. The rats in each group were intragastrically administered with corresponding liquid or normal saline twice a day for 14 days. During the intervention period， the general conditions of rats’ hair， spirit， diet and defecation were observed. After the last gavage， the pathological changes of esophageal tissue and the ultrastructure of ICC were observed. The relative expression and positive expression levels of p62， autophagy-related protein 8 （ATG8）， 200 kDa FAK family kinase-interacting protein （FIP200） and Unc-51 like autophagy activating kinase 1 （ULK1） in esophageal tissue were detected.RESULTS Compared with the blank group， rats in the model group exhibited listlessness； thickening of the esophageal basal layer， elongation of lamina propria papillae with inflammatory cell infiltration； markedly dilated endoplasmic reticulum appearing as round vacuolar cisternae with ribosome detachment； and a small number of accumulated autophagosomes. The relative expression and positive expression levels of p62， ATG8， FIP200， and ULK1 were significantly decreased （ P ＜0.05）. Compared with the model group， the above pathological injuries in the medium- and high-dose Tiaozhong huashi decoction groups had all improved to varying degrees； the damaged endoplasmic reticulum structure was repaired， and no autophagosome accumulation was observed. In particular， the relative expression levels and positive expression levels of p62， ATG8， FIP200， and ULK1 in esophageal tissue of rats in the medium-dose Tiaozhong huashi decoction group were significantly increased （ P ＜0.05）.CONCLUSIONS Tiaozhong huashi decoction ameliorated esophageal mucosal injury in GERD rats， and its mechanism was possibly associated with activation of the p62 signaling pathway and restoration of the endoplasmic reticulum structure， morphology， and autophagic capacity of ICC.

Objective:To construct a predictive model for urinary tract infection in patients with cervical spine fracture based on the random forest (RF) algorithm and evaluate its predictive performance.Methods:A retrospective cohort study was conducted to analyze the clinical data of 400 patients with cervical spine fracture admitted to West China Hospital of Sichuan University from October 2020 to February 2025, including 311 males and 89 females, aged 12-87 years [(48.5±14.8)years]. According to the occurrence of urinary tract infection during hospital stay, the patients were divided into urinary tract infection group ( n=57) and non-urinary tract infection group ( n=343). General information, disease-related data, and serological laboratory indicators during hospital stay were recorded in both groups. Viriables for urinary tract infection in patients with cervical spine fracture were analyzed and identified through univariate analysis and Lasso regression analysis. Using the bootstrap method with 500 resamples, the data were randomly allocated into the training set ( n=281) and test set ( n=119) at a ratio of 7∶3. An RF prediction model for urinary tract infection in patients with cervical spine fracture was constructed in the training set and the variable importance for the model was calculated. The constructed RF prediction model was validated in the test set, with the predictive accuracy, sensitivity, specificity, and the area under the receiver operating characteristic (ROC) curve (AUC) calculated to evaluate its predictive performance. Results:Univariate analysis showed that age, body mass index (BMI), length of hospital stay, concurrent hepatic impairment, concurrent benign prostatic hyperplasia, indwelling catheterization, duration of indwelling catheterization, immunosuppressant use, fracture site, cervical spinal cord injury, Frankel grade, time from injury to surgery, red blood cell count (RBC), hemoglobin (Hb), white blood cell count (WBC), albumin (Alb), globulin (GLO), blood urea nitrogen (BUN), and C-reactive protein (CRP) were significantly associated with urinary tract infection in patients with cervical spine fracture ( P<0.05). Among them, 9 viriables screened through Lasso regression analysis were age, length of hospital stay, concurrent hepatic impairment, concurrent benign prostatic hyperplasia, indwelling catheterization, duration of indwelling catheterization, Frankel grade, time from injury to surgery, and RBC. Based on the 9 viriables, a predictive model for urinary tract infection in patients with cervical spine fracture was constructed using the RF algorithm. Based on the mean decrease in Gini coefficient in the RF model, the top 6 important variables were duration of indwelling catheterization, length of hospital stay, RBC, age, time from injury to surgery, and Frankel grade in sequence. In the test set, the model achieved a prediction accuracy of 87.4%, sensitivity of 88.2%, specificity of 82.4%, and AUC of 0.89 (95% CI 0.80, 0.93). Conclusion:The RF prediction model for urinary tract infection in patients with cervical spine fracture is constructed based on 9 predictors including duration of indwelling catheterization, length of hospital stay, RBC, age, time from injury to surgery, Frankel grade, concurrent hepatic impairment, concurrent benign prostatic hyperplasia, and indwelling catheterization, with the first 6 viriables ranked as the most important factors, and demonstrates favorable predictive performance.

Objective This study aimed to adapt the data-driven Palliative Care Outcomes Collaboration(PCOC)model to the local context and evaluate its feasibility and preliminary effectiveness in a palliative care unit in China,with the goal of informing its broader integration into national palliative care practice.Methods Based on international experience,a localized implementation protocol for the PCOC model was developed through expert con-sultations and a pilot study.The protocol incorporated key elements including organizational and managerial sup-port,team training and capacity building,information system integration,supervision and feedback mechanisms,pro-cess optimization,and data-driven decision-making.From June to December 2023,the protocol was piloted in the palliative care unit of a tertiary cancer hospital in Changsha,China.Implementation outcomes were assessed by comparing patients' urgent care response rates,symptom stability rates,and symptom improvement rates between the first 1～3 months and 4～6 months after implementation.Results During the study period,a total of 355 inpatients were enrolled,with the PCOC assessment achieving full coverage(100％)and a completion rate of 97.78％.There was no statistically significant difference in the urgent needs response rate between the first 1～3 months and the 4～6 months after the implementation of the PCOC model(P=0.533).However,compared to the first 1～3 months af-ter implementation,patients in the 4～6 months period showed significantly higher symptom stability rates for pain,psychological/spiritual issues,and family/caregiver problems,as well as a higher improvement rate for pain(P＜0.05).Conclusion The localized PCOC implementation protocol facilitates standardized assessment and symptom manage-ment,and its application can enhance the quality of palliative care.

Objective To observe the efficacy and safety of Buyi Pishen Prescription combined with alisartan ester tablets in patients with primary chronic kidney disease stage 3(CKD3)with spleen-kidney qi deficiency syndrome.Methods Totally 80 patients were divided into treatment group and control group using a random number table method,with 40 cases in each group.Both groups received basic treatment and alisartan ester tablets(1 tablet/day,once daily,orally).The treatment group additionally received the Buyi Pishen Prescription(1 dosage/day,twice daily,orally).Both groups were treated for 24 weeks.TCM syndrome efficacy and clinical efficacy were evaluated.At 8,16 and 24 weeks,24-hour urinary protein(24 hUpro),serum creatinine(SCr),blood urea nitrogen(BUN),estimated glomerular filtration rate(eGFR)and TCM syndrome scores were measured.Serum oxidative stress markers(SOD,GSH-Px,MDA)were assessed before and after treatment.Blood potassium and liver function were monitored throughout.Results The total effective rate for TCM syndrome efficacy was 82.50%(33/40)in the treatment group and 60.00%(24/40)in the control group(P<0.05),and the treatment group was better than the control group.The total clinical efficacy rate was 77.50%(31/40)in the treatment group and 50.00%(20/40)in the control group,and the treatment group was better than the control group(P<0.05).Compared with before treatment,the treatment group showed a significant decrease in 24 hUpro and SCr at weeks 8,16 and 24,a significant decrease in BUN at weeks 16 and 24,and a significant increase in eGFR at weeks 8,16 and 24(P<0.01);the control group showed a decrease in 24 hUpro at weeks 8,16 and 24 of treatment(P<0.05),a decrease in SCr at weeks 16 and 24 of treatment(P<0.05),and an increase in eGFR at weeks 16 and 24 of treatment(P<0.05).In addition,the treatment group had lower 24 hUpro and SCr at weeks 16 and 24 of treatment than the control group(P<0.05,P<0.01),and higher eGFR than the control group(P<0.05,P<0.01).Compared with before treatment,the total scores of both the treatment group and control group significantly decreased at 16 and 24 weeks of treatment(P<0.01).The total scores of the treatment group were significantly lower than those of the control group at 8,16 and 24 weeks of treatment(P<0.01).Compared with before treatment,both groups showed a significant increase in serum SOD levels(P<0.05,P<0.01)and a significant decrease in MDA levels after treatment(P<0.05,P<0.01).The improvement in the treatment group was more significant than that in the control group(P<0.05).Both groups showed no abnormalities in blood potassium and liver function.Conclusion Buyi Pishen Prescription combined with alisartan ester tablets can reduce the levels of 24 hUpro,BUN and SCr,improve eGFR,alleviate TCM symptoms,and delay CKD progression in CKD3 patients with spleen-kidney qi deficiency syndrome,which can effectively reduce the serum MDA level and increase the antioxidant enzyme SOD level in patients,and its mechanism may be related to improving oxidative stress levels.
