ObjectiveTo conduct a comparative quality analysis of Inulae Flos， fuzz of Inulae Flos and calyx of Inulae Flos， elucidating the scientific connotation of the "removing calyx" process in the traditional processing of Inulae Flos. MethodsInulae Flos decoction pieces were collected， and the fuzz and calyx of Inulae Flos were prepared according to the experiences of old medicine workers. Subsequently， according to the methods under the "Inulae Flos" item in the 2025 edition of the Pharmacopoeia of the People's Republic of China， the appearance characteristics and thin-layer chromatography（TLC） identification of these samples were tested， and the moisture content， total ash content， extract content were also measured. The characteristic fingerprint patterns of Inulae Flos and fuzz of Inulae Flos were established by high-performance liquid chromatography（HPLC）， followed by similarity evaluation， principal component analysis（PCA）， and partial least squares-discriminant analysis（PLS-DA）. The contents of cryptochlorogenic acid， caffeic acid， 1，3-O-dicaffeoylqunic acid， 1，5-O-dicaffeoylqunic acid， and 1-O-acetyl britannilactone were determined to compare the quality differences of Inulae Flos， fuzz of Inulae Flos， and calyx of Inulae Flos. ResultsThe moisture content of Inulae Flos， fuzz of Inulae Flos， and calyx of Inulae Flos was all<10%. The determination results of total ash content were as follows：Calyx of Inulae Flos>Inulae Flos>fuzz of Inulae Flos， and the determination results of alcohol-soluble extract content were as follows：Fuzz of Inulae Flos>Inulae Flos>calyx of Inulae Flos. HPLC fingerprint patterns of Inulae Flos and fuzz of Inulae Flos were established， and 22 common peaks were identified. The similarity analysis and PCA showed that the overall quality of Inulae Flos and fuzz of Inulae Flos was similar， while the overall quality of calyx of Inulae Flos differed significantly from that of Inulae Flos and fuzz of Inulae Flos. PLS-DA results showed that Inulae Flos， fuzz of Inulae Flos， and calyx of Inulae Flos clustered into distinct groups， indicating significant differences among them. Cryptochlorogenic acid and caffeic acid had relatively high contents in calyx of Inulae Flos， the contents of 1，3-O-dicaffeoylqunic acid and 1，5-O-dicaffeoylqunic acid in Inulae Flos and fuzz of Inulae Flos were higher than those in calyx of Inulae Flos. The order of 1-O-acetyl britannilactone content was determined as follows：fuzz of Inulae Flos>Inulae Flos>calyx of Inulae Flos. ConclusionThe scientific nature of "Removing Calyx" process in the cleansing of Inulae Flos by old medicine workers is demonstrated by the resulting fuzz of Inulae Flos decoction pieces exhibiting enhanced cleanliness and higher content of the index component 1-O-acetyl britannilactone. This study provides a reference basis for further improving and enhancing the processing method and quality control standards of Inulae Flos.

Chronic post-surgical pain (CPSP) is a common long-term complication following lung surgery. Its high incidence significantly impacts patients’ quality of life and functional recovery, and imposes a substantial socioeconomic burden. This consensus aims to systematically establish a standardized integrated Chinese and Western medicine diagnostic and treatment framework for chronic post-lung surgery pain (CPLSP). Based on the latest domestic and international evidence-based medical research and multidisciplinary clinical experience, the working group comprehensively elaborates on core issues regarding CPLSP, including its definition, epidemiology, pathogenesis, clinical assessment, Western medical treatment, traditional Chinese medicine (TCM) treatment, and integrated strategies. The consensus emphasizes a patient-centered approach, adhering to the principles of multimodality, individualization, and stepwise management, highlighting the synergistic advantages of integrating Chinese and Western medicine throughout the entire perioperative management cycle encompassing "perioperative anti-inflammation, acute analgesia, and chronic rehabilitation." Through systematic literature retrieval and evidence integration, a total of 9 core recommendations were established to provide scientifically sound and clinically practical guidance.

Objective: To investigate the association of special family structure and physical activity with psychological sub health among secondary vocational school students, so as to provide reference to inform mental health promotion in the population. Methods: From September to December 2024, a convenience sample was drawn from 16 schools including 5 141 secondary vocational school students across 8 provinces (municipalities) in China (Fujian, Chongqing, Guangdong, Guangxi, Hubei, Jiangxi, Shanghai, Zhejiang). A self developed questionnaire, Multidimensional Sub health Questionnaire of Adolescents and International Physical Activity Questionnaire Short Form were used to investigate and evaluate basic information, family structure, psychological sub health status and physical activity. Descriptive statistics and Logistic regression analysis were performed to explore relationships of special family structures and physical activity with psychological sub health in secondary vocational school students. Results: The detection rate of psychological sub health among secondary vocational school students was 11.0%. The reporting rates for secondary vocational school students who lost their father or lost their mother, whose parents divorced, whose parents remarried, and those from special family structures were 2.8%, 0.8%, 11.8%, 3.9%, and 14.7%, respectively. Moreover, the detection rates of psychological sub health and its sub dimensions significantly differed among secondary vocational school students grouped by family type (divorced parental families, remarried parental families and special family structures)( χ 2=5.90-22.67, all P <0.05). Binary Logistic regression indicated that maternal bereavement was associated with a higher risk of conduct problems [ AOR ( 95% CI )= 2.90(1.15-7.33)], and parental divorce was associated with a higher risk of psychological sub health ( AOR= 2.71 , 95%CI =1.04- 7.06 ) among secondary vocational school students (both P <0.05). Interaction analysis showed that both students with a special family structure and insufficient physical activity [ AOR (95% CI )=1.99(1.44-2.75)] and those with a non-special family structure and insufficient physical activity [ AOR (95% CI )=1.81(1.48-2.22)] were associated with increased risks of psychological sub health among secondary vocational school students (both P <0.01). Conclusion Special family structure and physical activity are associated with psychological sub health among secondary vocational school students; early identification and assessment based interventions for those with a special family structure should be strengthened, while school based physical activity should be implemented to increase physical activity levels,thereby reducing the risk of psychological sub health.

Patients with lung cancer experience a heavy symptom burden during the perioperative period, which seriously affects their recovery and quality of life. Traditional symptom management models rely mainly on scheduled ward rounds during hospitalization and outpatient follow-up after discharge. However, they have limitations such as delayed symptom recognition, lack of post-discharge monitoring, and non-quantitative symptom assessment, which often lead to delayed interventions and low patient satisfaction. In recent years, the symptom management model based on electronic patient-reported outcomes (ePRO) has been increasingly valued in clinical practice. Existing high-level evidence from both domestic and international studies indicates that, through proactive monitoring, real-time alerts, and remote interventions, this model enables dynamic and continuous symptom management and helps improve patient recovery and healthcare experience. As a supplement to routine medical care, the ePRO-based symptom management model aims to enhance the quality of care rather than replace existing medical processes. To promote the standardized application of this model in perioperative lung cancer care, this consensus integrates domestic and international evidence. After multiple rounds of voting by more than 50 experts, it formulates 12 consensus statements covering the three core components, symptom monitoring, alerting, and intervention, to provide scientific and practical recommendations for clinical practice.

Objective: To investigate the prevalence of co-occurrence of common diseases among junior high school students in Yunnan Province and to identify latent comorbidity patterns and analyze their associated factors, so as to provide evidence for the comprehensive prevention and control of common diseases among students. Methods: From September to November 2025, a stratified cluster sampling method was employed to survey 71 791 students in grades 7-9 recruited from 258 junior high schools in Yunnan Province. Information on six common diseases, including screening myopia, dental caries, overweight/obesity, malnutrition, elevated blood pressure, and abnormal spinal curvature, was collected through physical examinations and questionnaire surveys, along with data on demographic characteristics, physical activity, and sleep. Latent class analysis (LCA) was used to identify comorbidity patterns of common diseases, and multinomial Logistic regression was performed to analyze the factors associated with each pattern. Results: The detection rates of screening myopia, dental caries, overweight/obesity, elevated blood pressure, malnutrition, and abnormal spinal curvature among junior high school students were 65.2%, 62.1%, 22.4%, 10.9% , 8.2%, and 5.7%, respectively. LCA identified three latent comorbidity patterns of common diseases: a high prevalence screening myopia-dental caries-spinal curvature abnormality pattern (C1, 63.8%), an overweight/obesity elevated blood pressure pattern (C2, 24.1%), and a relatively low burden pattern (C3, 12.0%). With C3 as the reference, multinomial Logistic regression showed that girls were more likely than boys to be assigned to C1 and C2 [ OR (95% CI )=2.12(2.02-2.23), 1.31(1.23-1.38)]; non-Han students were less likely than Han students to belong to C1 and C2 [ OR (95% CI )=0.88(0.83-0.92), 0.81(0.77-0.86)]; students in grades 8 and 9 were more likely than those in grade 7 to belong to C1 and C2, with the highest likelihood observed among grade 9 students [ OR (95% CI )=1.43(1.35-1.52), 1.27(1.19-1.36)]; insufficient sleep was associated with increased odds of belonging to C1 and C2 [ OR (95% CI )=1.15(1.09-1.22), 1.25(1.18-1.33)] (all P <0.05). Compared with students who engaged in outdoor activities during breaks, those who stayed indoors, either inside the teaching building but outside the classroom or inside the classroom, were more likely to belong to C1 [ OR (95% CI )=1.09(1.02-1.16), 1.17(1.09-1.26)] and C2 [ OR (95% CI )=1.13(1.05-1.21), 1.25(1.15-1.35)]; students not living with their parents were less likely to belong to C1 and C2 [ OR (95% CI )=0.83(0.77-0.90), 0.74(0.68-0.81)] (all P <0.05). Conclusions The co-occurrence of common diseases is relatively prominent among junior high school students in Yunnan Province, with distinct latent stratification patterns. Tiered and precise comprehensive interventions should be implemented targeting key populations to promote the prevention and control of common diseases among students.

Standardized clinical trial reporting is crucial for ensuring the scientific validity,reproducibility,and clinical translational value of reported results.The Consolidated Standards of Reporting Trials(CONSORT)statement,an internationally recognized guideline for randomized controlled trials(RCTs),has become an important reference standard for writing research papers in medicine since the 2010 version of CONSORT was published.With advancements in scientific research methodologies and the emergence of new forms of clinical trials,the CONSORT working group released an updated version in April 2025,published in journals such as The BMJ.Herein,we provide a systematic interpretation of the core revisions of CONSORT 2025,as well as a comparison with CONSORT 2010 to highlight the key differences.By providing practical,example-based recommendations,we aim to help domestic researchers apply the new guidelines efficiently,thereby improving the quality of clinical trial reports authored by domestic researchers.

A high-quality clinical trial protocol is the cornerstone for ensuring the scientific integrity and ethical compliance of a study.The Standard Protocol Items:Recommendations for Interventional Trials(SPIRIT)has become the international benchmark for developing clinical trial protocols since its release in 2013.To adapt to the developing trends of open science and patient-centered principles,the SPIRIT group completed a comprehensive update in 2025.While retaining its core structure,this updated guideline introduces a new open science module and incorporates several new elements,including patient and public involvement,trial monitoring,and data sharing,alongside substantial revisions of five pre-existing items.In this article,we critically examine the core revisions in SPIRIT 2025 and,through analysis of representative case studies,illustrate the practical application of the new reporting guideline in drafting trial protocols.Our goal is to to provide Chinese researchers with a valuable reference for understanding and implementing this new reporting guideline,thereby enhancing the quality and rigor of clinical trial protocols developed in the country.

Objective:To investigate the method and clinical efficacy of simultaneous correction of sunken upper eyelid during double eyelid plasty.Methods:A retrospective analysis was conducted on patients with single eyelids and sunken upper eyelid treated at the Department of Plastic Surgery, the First People’s Hospital of Zhengzhou, from October 2022 to February 2024. All patients underwent incisional double eyelid plasty with individualized correction based on depression severity. For mild depression, a combination of pretarsal orbicularis oculi muscle flap folding and orbital septum fat flap transposition was performed for correction. For moderate depression, additional autologous stromal vascular fraction (SVF)-gel grafting would be performed if residual depression persisted after the aforementioned approach. For severe depression, if the orbital fat was sufficient, the orbicularis oculi muscle flap folding, orbital fat flap repositioning and autologous SVF-gel transplantation were used. If there was insufficient orbital fat, the correction involved the use of a orbicularis oculi muscle flap and SVF-gel transplantation. Postoperative follow-up was conducted regularly, and related complications were statistically analyzed. Six months after the surgery, two blinded plastic surgeons evaluated outcomes via visual analog scale (VAS), including five aspects: symmetry of palpebral folds(including width and curvature of the double eyelid fold), fold contour, depression improvement, scar quality, overall eyelid aesthetics. Each aspect was rated on a scale from 1 to 10, with higher scores indicating better outcomes. Patient satisfaction was scored separately (1-5 per item), with higher scores indicating greater satisfaction.Results:A total of 64 patients were enrolled, including 4 males and 60 females; the age ranged from 19 to 66 years[ (32.0±9.7) years]. The degree of sunken upper eyelid was mild in 33 cases, moderate in 19 cases and severe in 12 cases. All patients underwent double eyelid plasty and orbicularis oculi flap folding. Based on this, 45 cases (33 mild and 12 moderate cases) underwent orbital septum fat flap transposition, 11 severe cases underwent SVF-gel grafting, and 8 cases (7 moderate and 1 severe cases) required combined approaches to correct depression. During the procedure, 19 cases (38 sides) received (1.8±0.8) ml of SVF-gel injection. Among these cases, one case with severe sunken upper eyelid who did not receive orbital fat transfer was injected with high density fat (left side: 0.6 ml, right side: 0.8 ml) due to insufficient SVF-gel volume. Two cases with severe sunken upper eyelid who only had autologous SVF-gel transplantation did not fully correct the depression within 3 months post-surgery received a second SVF-gel injection[(1.0±0.1) ml]. Follow-up was conducted for 6 to 12 months after surgery. All patients experienced varying degrees of eyelid edema, which typically lasted 2 to 3 months. Ecchymosis (34 sides), conjunctival congestion (3 sides), and temporary ptosis (5 sides) all resolved within 2 weeks. Pigmentation (14 sides) and scar hyperplasia (3 sides) disappeared or stabilized within 6 months. No patients developed complications such as incision infection, hematoma, fat liquefaction, local skin unevenness, or induration. The surgeons’ VAS scores of the above five indicators were all > 8 points, and the satisfaction scores of patients for the five indicators were all > 4 points. In both scoring, the improvement of sunken upper eyelid scored the highest, which were (9.2 ± 0.9) points and (4.8 ± 0.6) points respectively.Conclusion:For patients with single eyelids and varying degrees of sunken upper eyelid, performing double eyelid plasty and orbicularis oculi muscle flap folding, individualized correction is achieved through autologous fat redistribution techniques, based on the severity of the sunken upper eyelid and the amount of orbital fat. This single procedure can restore upper eyelid volume and rejuvenate the appearance, resulting in a natural and aesthetically pleasing double eyelid with minimal complications and high patient satisfaction.

This review summarizes recent advances in neoadjuvant immunotherapy for advanced gastric cancer.Through literature search in PubMed,Web of Science,and CNKI databases from 2020 to 2023,we systematically analyzed the mechanisms,clinical applications,and bio-marker research.Programmed death-1(PD-1)inhibitors combined with chemotherapy significantly improve patient outcomes,while mi-crosatellite instability(MSI),programmed death-ligand 1(PD-L1)expression,and tumor mutational burden(TMB)have been identified as important predictive biomarkers.Multi-omics analysis shows great potential in identifying optimal responders,with pyroptosis-related gene scoring system(PRS)positively correlating with anti-tumor immune infiltration.Metabolic reprogramming and epigenetic regulation in the tumor microenvironment play key roles in immune evasion,while emerging targets such as Claudin 18.2 and combination targeting strategies further enhance therapeutic efficacy.Despite significant progress,precise patient selection and overcoming resistance mechan-isms remain major challenges.Future research should focus on biomarker validation,personalized treatment strategy development,tumor microenvironment dynamic analysis,and novel combination therapy exploration to improve clinical outcomes.
