Objective:
To explore the association of vegetables and fruits intake with depressive symptoms among multi ethnic first year junior high school students in Yunnan Province, so as to provide data support for preventing and reducing depressive symptoms among first year junior high school students.
Methods:
From October to December 2022, a cluster random sampling method was used to select 8 500 first year junior high school students from 11 ethnic minority areas in Yunnan Province (Fugong County, Longling County, Longyang District, Luchun County, Mojiang County, Nanjian County, Qiaojia County, Shuangjiang County, Tengchong City, Yuanmou County, Zhenyuan County), to investigate with a questionnaire. The Dietary Frequency Questionnaire was used to collect dietary behavior datas, and the Chinese version of Depression Anxiety Stress Scale-21 (DASS-21) was used to assess depressive symptoms. The generalized linear model was used to analyze the association of vegetable and fruit intake with depressive symptoms in students, and stratified analysis was performed according to ethnicity.
Results:
The detection rate of depressive symptoms among first year junior high school students in Yunnan Province was 29.5%. The detection rates of depressive symptoms in Han and minority first year junior high school students were 26.9% and 31.6%. After controlling for demographic variables such as gender, age, family residence and other confounding factors, the generalized linear model analysis results showed that the intake of leafy vegetables ( β= -0.07 , 95%CI =-0.12 to -0.01), flat fruits ( β=-0.06, 95%CI =-0.12 to -0.00) and hot natured fruits ( β=0.11, 95%CI = 0.04- 0.17) were associated with depressive symptoms in Han first year junior high school students (all P <0.05). The intake of melon and fruit vegetables ( β=-0.06, 95%CI =-0.11 to -0.01) and hot natured fruits ( β=0.06, 95%CI =0.01-0.12) were associated with depressive symptoms in ethnic minority first year junior high school students (both P <0.05).
Conclusions
The intake of vegetables and fruits among multi ethnic first year junior high school students in Yunnan Province is related to the risk of depressive symptoms. It is suggested to strengthen the consumption guidance and education of vegetables and fruits to prevent depressive symptoms among first year junior high school students.

Severe acute pancreatitis (SAP) is closely related to dysfunction of the spleen-stomach ascent and descent. Due to the influence of modern lifestyle and dietary factors, Qi deficiency in the spleen and stomach has become the pathological basis of SAP. Its pathogenesis is characterized by dampness, heat, pathogenic factors, stasis, stagnation, obstruction, Fu-organs Qi obstruction, pathogenic excess, and healthy Qi deficiency. At different stages of the disease course of SAP, there is a focus on both pathogenic excess and healthy Qi deficiency. It is specifically manifested as Fu-organs stagnation and heat accumulation, as well as pathogenic excess and healthy Qi deficiency, during the systemic inflammatory response phase, intermingling of blood stasis and pathogenic factors, as well as Qi deficiency and blood stasis, during the infection period, and weakness of the spleen and stomach, as well as healthy Qi deficiency and lingering pathogenic factors, during the residual infection period. Based on the theory that "the spleen and stomach are the acquired foundation", a staged treatment method centered on the core principle of "strengthening healthy Qi to eliminate pathogenic factors" was developed. The staged treatment method included "clearing the Fu-organs to expel turbidity, replenishing Qi to harmonize the stomach, activating blood circulation to expel pathogenic factors, replenishing Qi to relieve pain, promoting digestion to stimulate appetite, and replenishing Qi to invigorate the spleen". In clinical practice, Hewei Tongxie mixture, Yikang mixture, and Shiwei Jianpi Xiaoshi powder were selected for staged treatment of SAP. This article systematically summarized the theoretical basis of traditional Chinese medicine, Western medicine foundation, modern pharmacological mechanisms, and clinical application experience of the staged treatment of SAP with "strengthening the healthy Qi to eliminate pathogenic factors", providing new ideas for the treatment of SAP with traditional Chinese medicine.

Objective: To evaluate the methodological quality and reporting quality of clinical practice guidelines or expert consensus on blood transfusion and blood use (BTBU) in China (hereinafter referred to as "guidelines/consensus"), providing reference for the development and updating of future BTBU guidelines/consensus. Methods: A systematic search was conducted in Chinese databases such as China National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Data-base, relevant guideline release platforms, and professional association websites. BTBU-related guidelines/consensus published between January 2006 and December 2025 were included. According to the inclusion and exclusion criteria, after completing literature screening and data extraction, three evaluators independently assessed the quality of the included literature using the Scientificity, Transparency, and Applicability of Guidelines Rating Tool (STAR), the Appraisal of Guidelines for Research and Evaluation Ⅱ (AGREE Ⅱ), and the International Practice Guideline Reporting Standards (RIGHT). Results: A total of 29 documents were included, including 5 guidelines, 22 consensus statements, and 2 protocols. The results of the STAR assessment showed that the total score was (21.7±8.8)%. The domain score ratios for registration, research protocol, funding, working group, conflict of interest, clinical question, evidence, consensus method, recommendation, accessibility and other domains were (2.2±12.1)%, 0, (36.7±25.1)%, (18.3±7.6)%, (19.2±15.3)%, (16.6±23.1)%, (15.1±6.3)%, (9.6±21.2)%, (54.3±18.4)%, (31.7±10.4)% and (10.3±31.0)%, respectively. For the AGREE Ⅱ assessment, the methodological quality of 26 articles was rated Grade B and 3 articles Grade C. The results of the RIGHT assessment indicated that the overall reporting rate of all guidelines/consensuses was (65.3±4.0)%. Conclusion: The methodological and reporting quality of current expert guidelines/consensus on BTBU in China still need improvement, and guidelines and consensus should be strictly formulated and standardized according to the standards of STAR, AGREE II and RIGHT.

Objective: To evaluate the in vitro procoagulant efficacy and in vivo potential thrombogenic risk of self-prepared activated prothrombin complex concentrate (aPCC). Methods: The preparation was administered at a dose of 0.5 IU per milliliter of plasma. For in vitro assays, the self-prepared aPCC concentrate was added to plasma spiked with factorⅧ (FⅧ) inhibitors. Calibrated automated thrombin generation (CAT), prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), and fibrinogen (Fib) quantification were performed. Normal saline and FEIBA
were set as controls to evaluate the procoagulant capacity of the self-prepared aPCC concentrate. For in vivo animal studies, the self-prepared aPCC concentrate was injected into rats via the jugular vein. A ferric chloride (FeCl3) filter paper patch was applied to induce carotid arterial thrombosis. Laser speckle blood flow imaging was used to continuously monitor thrombus formation in the rat carotid artery. Plasma samples were collected from rats for CAT, PT, APTT, TT and Fib testing, with normal saline and FEIBA
as controls to evaluate the potential thrombogenic risk of the self-prepared aPCC concentrate. Results: Supplementation with aPCC significantly shortened APTT and PT values in inhibitor-spiked plasma (all P<0.001). There were no statistically significant differences in APTT and PT between FEIBA
and self-prepared aPCC (P>0.05). CAT results demonstrated that adding aPCC to inhibitor-containing plasma markedly increased endoge-nous thrombin potential (ETP) and peak thrombin concentration (Peak) (P<0.001), with both parameters higher than those of normal plasma (P<0.05). No significant intergroup difference in ETP was observed between self-prepared aPCC and FEIBA
(P>0.05). Carotid blood flow imaging in rats revealed that, compared with FEIBA
, thrombi induced by self-prepared aPCC were smaller and less stable, and all underwent spontaneous lysis, accompanied by better restoration of carotid blood perfusion. Conclusion: The self-prepared aPCC restores coagulation function in inhibitor-spiked plasma to a comparable extent as FEIBA
, while exhibiting a lower thrombogenic risk.

Quality control (QC) of biospecimens from oral and maxillofacial tumors patients constitutes a critical foundation for the prevention, diagnosis, treatment, and precision medicine research of these diseases. Biospecimen quality directly governs the discovery and validation of disease biomarkers, the elucidation of pathogenesis, and the efficacy of clinical translation. QC spans the entire biospecimen lifecycle—encompassing collection, processing, storage, transportation, and utilization. Its primary objectives are to ensure sample integrity, reliability, traceability, and consistency, thereby guaranteeing the robustness of research data; the accuracy of molecular subtyping, biomarker identification, and treatment response prediction; and the precision of clinical decision-making. However, current QC frameworks for these biospecimens remain underdeveloped. Drawing on domestic and international technical standards, regulatory guidelines, and recent research advances, this paper elaborates on the importance of implementing a QC management system throughout the biospecimen lifecycle. It focuses on QC methodologies tailored to diverse biospecimen types, examining how standardized sampling procedures, regulated preprocessing workflows, and optimized long-term storage conditions influence sample quality. We aim to provide concrete guidance and a transferable paradigm for establishing standardized QC protocols and an informatics-enabled traceability system specific to oral and maxillofacial tumors. Such efforts are intended to enhance the research value and clinical utility of these biospecimens, furnishing reliable sample resources and technical support for the development of precision diagnostics and therapeutics. Furthermore, we advocate for a dual-track “QC plus Ethics” management framework within biobanks. This approach would reinforce ethical and legal safeguards, establishing a robust barrier to support safe scientific innovation and clinical translation.

ObjectiveTo assess the risk of vector-born infectious diseases by monitoring the major vectors in the relevant venues of the 19th Hangzhou Asian Games in Fuyang competition area, so as to provide references for the prevention and control of vector in similar large-scale events or activities in the future. MethodsFrom April to October 2023, monitoring and evaluation of rodent, mosquito, fly and cockroach density levels were carried out in various venues and reception hotels in Fuyang competition area (venues and hotels were the 1st circle area, and various environments and places in the surrounding 500 meters were the 2nd circle area). SPSS 25.0 software was used to analyze the data, and chi-square test or Fisher’s precision probability test were used to calculate the qualified rate and positive rate. Moreover, the path index, landing index and Bretrau index were analyzed by Kruskal-Wallis H test. ResultsThe control effect of vector density in the 1st circle was significantly better than that in the 2nd circle. Since September, the monitoring indices of the venues in the two circles had reached the national A-level and B-level standard, respectively. The positive rate of rodent traces generally showed a trend of first increasing and then decreasing, and the peak was shown to occur in July and August, with the highest rate of 5.38%. The qualified rate of rodent prevention facilities continued to rise, and facilities in the 1st and 2nd circles had reached national A-level and B-level standard respectively in late August. The landing index and path index of mosquitoes basically showed a changing trend from high to low, with the highest landing index of 4.56 individuals·person-time-1 and the highest path index of 2.44 places·km-1.The adult fly infestation rate remained at a low level, with the highest rate of 4.17%, and the minimum qualified rate of fly prevention facilities was 28.57%, which reached the national standard after July. The positive detection rates of adult flies and cockroach traces showed no significant pattern, with the highest rate of 7.00% and 8.33%, respectively. The detection rate of live ootheca was always at a low level. ConclusionThe relevant venues in the Fuyang competition area of the 19th Asian Games in Hangzhou meet national standards in terms of vector control indicators such as rodents, mosquitoes, flies, cockroaches and other vectors. By means of environmental improvement, facilities for preventing rodents and flies, and deepening biological and chemical prevention and control methods, it can be ensured that there will be no vector-borne diseases and infestation incidents during the event.

Childhood is a critical period for growth and development, and the oral microbiota, as the second most diverse microbial community in the human body, plays a pivotal role in maintaining children's health. Recent studies have demonstrated that dysbiosis of the oral microbiota not only contributes to oral diseases such as dental caries and periodontitis but may also influence the development of children's skeletal, nervous, digestive, cardiovascular, and immune systems through mechanisms involving inflammatory responses, metabolic regulation, and cross-organ communication networks. This review systematically examines the role of the oral microbiota in childhood growth and development and, guided by the core principles of the "active health" model, proposes multiple intervention strategies—including probiotics, xylitol, and mouthwashes—to optimize children's health through early oral microbiota modulation.

To investigate the correlation between vitamin D nutritional status and insulin resistance in pubertal adolescents. This cross-sectional observational study employed convenience sampling to recruit 2021-grade(8th grade) students from Jining No.7 Middle School in Shandong Province on June 5, 2023. Data collection included questionnaires, physical examinations, and imaging assessments to obtain general information, secondary sexual characteristics development, and bone age. Venous blood samples were collected to measure fasting blood glucose(FBG), fasting insulin(FINS), homeostasis model assessment of insulin resistance(HOMA-IR), and 25-hydroxyvitamin D[25(OH)D] levels. Spearman correlation analysis and multivariate linear regression models were used to examine the associations between serum vitamin D levels and FBG, FINS, and HOMA-IR. The study included 168 pubertal adolescents[69 females(41.1%), 99 males(58.9%); mean age(13.27±0.46) years]. All participants had entered puberty based on sexual development assessment. Vitamin D deficiency was observed in 41 participants(24.4%), insufficiency in 109(64.9%), and sufficiency in 18(10.7%). The median HOMA-IR was 3.49(2.57, 5.14).Significant differences were found across vitamin D status groups for HOMA-IR [4.45(2.54, 6.62) Vitamin D deficiency/insufficiency is prevalent among pubertal adolescents, and serum vitamin D levels show a significant inverse association with insulin resistance. These findings suggest the potential importance of vitamin D status in metabolic health during puberty.

To investigate body composition and associated factors in adolescents undergoing long-term regular sports training. This prospective longitudinal cohort study employed convenience sampling to recruit adolescents receiving structured athletic training at Jining Sports Training Center in June 2023. Baseline measurements included height, weight, body mass index (BMI), blood pressure, heart rate, waist circumference, and hip circumference. Questionnaires assessed sleep duration, screen time, and household income. Follow-up measurements in June 2024 repeated these assessments while adding bioelectrical impedance analysis for body composition (lean mass, skeletal muscle mass, fat mass, and body fat percentage). Linear regression models examined associations between training type (direct-contact vs. non-contact sports) and follow-up body fat percentage, BMI, and waist circumference as dependent variables, adjusting for covariates. The study included 110 adolescents (39 female, 71 male) with median age 13.21 years (IQR: 12.46-14.33). Participants comprised 65 direct-contact and 45 non-contact athletes. Baseline prevalence rates were 27.27% for overweight/obesity, 24.55% for elevated waist circumference, and 16.36% for elevated blood pressure. At follow-up, corresponding rates were 24.55%, 26.36%, and 13.64% respectively. The elevated blood pressure subgroup showed significantly higher waist circumference ( Despite regular athletic training, substantial proportions of adolescents exhibited overweight/obesity, abdominal obesity, and elevated blood pressure, warranting clinical attention. Training modality appears to influence body composition changes, with direct-contact sports associated with more favorable adiposity-related outcomes.

Congenital heart disease (CHD) is a congenital malformation resulting from abnormal embryonic development of the heart and great vessels, accounting for approximately 25% of all congenital malformations. Children with CHD are often complicated by short stature. Although surgical treatment can improve their growth and development to a certain extent, some children still experience growth retardation after surgery. Recombinant human growth hormone (rhGH) is the main drug for treating short stature, but its efficacy and safety in the treatment of patients with concomitant CHD warrant further investigation. This article reports six cases of children with CHD and short stature who were treated with rhGH. Through a literature review, we summarize and discuss the therapeutic efficacy, follow-up experiences, and adverse reactions of rhGH treatment, aiming to provide references for clinicians in applying rhGH to treat patients with CHD and short stature.
