As the core vehicle for preserving and transmitting traditional Chinese medicine（TCM） academic thought and clinical experience， the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine， this study conducted a comprehensive analysis of critical challenges， including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic， encompassing three dimensions of authenticity and standardization， characteristics and advantages， application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment， while aligning with modern scientific research standards， achieving a balance between individualized TCM experience and standardized evaluation. Concurrently， this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases， contributing significantly to the inheritance of TCM knowledge， evidence-based practice， and the reform of talent evaluation mechanisms.

Malignant tumors are major diseases with a high incidence worldwide and seriously threaten human health， and their occurrence and development are closely associated with the abnormal activation of multiple signaling pathways. Among them， the vascular endothelial growth factor （VEGF）/VEGF receptor （VEGFR） signaling pathway plays a key regulatory role in tumor angiogenesis， which can be widely implicated in tumor proliferation， invasion， and metastasis through regulating the expression of downstream signaling proteins and genes， serving as a key target for cancer targeted therapy. Traditional Chinese medicine （TCM） possesses unique advantages including multiple components， multiple targets， holistic regulation， and mild adverse reactions in cancer prevention and treatment. This paper systematically sorts out existing research findings and analyzes the anti-tumor mechanisms of TCM in modulating this signaling pathway. Furthermore， this paper summarizes that TCM active components （such as oxymatrine， quercetin， and celastrol）， extracts （such as Prunellae Spica extract and Cinnamomi Cortex extract）， and compound prescriptions （such as Yupingfeng San and modified Wenyang Sanjie Formula） can inhibit tumor angiogenesis， reverse epithelial-mesenchymal transition， improve the tumor microenvironment， promote cancer cell apoptosis， and suppress cancer cell proliferation， migration， and invasion by regulating the VEGF/VEGFR signaling pathway and its key molecules， thereby exerting anti-tumor effects. This review provides new ideas for the research and development of cancer drugs and the optimization of treatment regimens.

[Objective] To use Platelet Additive Solution Ⅲ M to suspend concentrated platelets and evaluate their quality at different storage periods, in order to investigate the optimal ratio of Ⅲ M to plasma in the medium for storing concentrated platelets. [Methods] Disposable plastic blood bags with platelet storage bags were used to collect whole blood from healthy voluntary blood donors, and concentrated platelets were collected by plasma-rich method, with a volume of about 50 mL and ≥4.0×10¹⁰ platelets contained in each bag. According to the Platelet Addictive Solution ⅢM/plasma volume ratio in the medium of suspended platelets, the platelets were divided into 3 groups: control group (plasma only), experimental group 1(Platelet Addictive Solution ⅢM/plasma volume ratio of 6.5∶3.5) and experimental group 2 (low plasma group, Platelet Addictive Solution ⅢM/plasma volume ratio of 9∶1), each group of 50 samples. Three groups of platelets were stored at (22±2) ℃ at a flat-bed shaker, and 5 mL were sampled by sterile connection at day 1, 3, 5 and 7 respectively to detect platelet count, pH value, lactate dehydrogenase, CD62P positive rate and Annexin V positive rate. All the data were analyzed with SPSS24.0 software. One-way ANOVA was employed to compare the differences among three groups. In order to pairwise comparisons between means of multiple samples, Bonferroni method was applied. [Results] With the extension of storage time, the platelet count decreased and the Annexin V positive rate increased in the 3 groups, and the difference of the 3 groups was not statistically significant (P>0.05). The pH value decreased in the 3 groups, with values at day 1, 3, 5 and 7 of 7.44±0.13 vs 7.44±0.14 vs 7.41±0.11, 7.31±0.68 vs 7.43±0.23 vs 7.22±0.12, 7.30±0.15 vs 7.42±0.14 vs 7.17±0.12, 7.29±0.33 vs 7.26±0.18 vs 7.04 ± 0.12, respectively. The pH decline in the control group and experiment group 1 was minor, with no statistically significant difference, but experiment group 2 showed relatively larger decreases in day 5 and day 7, with statistically significant difference (P<0.05). LDH concentrate was elevated in 3 groups (mmol/L), with values at day 1,3,5 and 7 of 169.62±99.33 vs 105.80±150.71 vs 77.14±105.38, 225.10±112.86 vs 116.00±72.77 vs 94.42±88.74, 249.42±79.55 vs 119.00±53.51 vs 118.35±80.39, 253.34±86.95 vs 147.71±90.71 vs 124.68±128.68 respectively. Compared with the control group, the difference was statistically significant (P<0.05). Experimental group1 had the smallest increase; CD62P positive rate increased in 3 groups (%), with values at day 1, 3, 5 and 7 of 26.22±11.74 vs 23.48±12.48 vs 40.49±11.86, 41.29±8.36 vs 33.53±25.64 vs 50.42±22.36, 59.59±10.13 vs 36.39±23.10 vs 50.94±20.50, 72.92±15.44 vs 55.54±23.65 vs 61.89±18.82 respectively. Compared with the control group, the increase in experiment group1 was smaller, and the difference was statistically significant (P<0.05). [Conclusion] Platelet Addictive Solution ⅢM/plasma volume ratio of 6.5∶3.5 is superior to traditional plasma in maintaining platelet quality during the in vitro preservation period of platelets.

Objectives: This study aimed to evaluate the correlation between mast cell (MC) density in rosacea-affected skin and the expression of key inflammatory mediators, including IL-6, TNF-α, and cathelicidin LL-37. By comparing lesions rich in MCs with those having fewer MCs, we sought to elucidate the role of MCs in the inflammatory mechanisms underlying rosacea pathogenesis.

Methods: Specimens were collected from 20 patients diagnosed with rosacea who attended the outpatient clinic between 2008 and 2013. Each specimen underwent staining using hematoxylin/eosin, Giemsa, IL-6, LL-37, and TNF-α for both histopathological and immunohistochemical analyses. The number of stained cells was counted across 10 randomly selected dermal layers at a magnification of ×400 using light microscopy. The results were categorized based on the number of MCs counted: more than 10 MCs were classified as MC-rich, and 10 or fewer MCs as MC-poor.

Results: Among the 20 patients (10 MC-rich and 10 MC-poor), the MC-rich group demonstrated significantly higher MC counts than the MC-poor group (P<0.001). However, there were no significant differences in the expression levels of IL-6, LL-37, or TNF-α between the two groups. Additionally, MC density did not show any significant associations with patient demographics, clinical characteristics, or systemic comorbidities.

Conclusion: Increased MC density was not associated with differences in IL-6, TNF-α, or LL-37 expression in rosacea lesions. These findings suggest that MC infiltration may not directly influence the inflammatory mediator profile in rosacea. Further research is required to identify distinctive pathological features or markers that can elucidate the mechanisms of rosacea.

Purpose: Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms. Materials and Methods: Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A. Results: TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer. Conclusion TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.

Objective To evaluate the association between self-reported neighborhood walkability environments and mortality in China.Methods The Prospective Urban Rural Epidemiology study in China(PURE-China)recruited 47 931 participants aged 35-70 from 12 provinces in China between 2005 and 2009.Neighborhood environmental indicators were collected using the Neighborhood Environment Walkability Scale(NEWS)questionnaire,with higher scores indicating better walkable environments.The primary outcomes were all-cause mortality and cardiovascular mortality,using Cox fragile model to evaluate the association between community walkability and outcomes,as well as exploring mediating pathways.Results Of 35 490 participants included in this study,60%were female,with a mean(SD)age of 51.5(9.6)years.The median follow-up was 11.7 years.This study found an association between higher community walkability score and reduced risk of all-cause mortality,with the total score(HR=0.85;95%CI,0.80-0.89),land-use mix(HR=0.84;95%CI,0.79-0.88),and crime safety(HR=0.84;95%CI,0.80-0.89)showing the most significant associations.NEWS can affect long-term adverse outcomes through lifestyle.Conclusions In the Chinese population,favorable community walkability is associated with lower all-cause mortality risk,which may support policymakers to take actions to mitigate the adverse effects of poor community en-vironments on health.

Objective To establish a stable,reliable,and clinically relevant porcine model of endotoxin-induced acute respiratory distress syndrome(ARDS).Methods Ten 8-month-old male Bama minipigs were deeply sedated,followed by invasive mechanical ventilation and electrocardiographic monitoring.Lipopolysaccharide(LPS)was intravenously pumped at 600 μg/(kg·h)for 3 hours,then maintained at 15 μg/(kg·h)thereafter.Dynamic monitoring was performed at five time points after LPS injection(LPS 0,1,3,5,and 8 h),including arterial blood gas analysis and chest computed tomography(CT)scans.Pathological examination of lung tissues obtained via bronchoscopic biopsy(HE staining and transmission electron microscopy)was conducted.These indicators were comprehensively used to evaluate the success of the animal model.Results At 5 hours after LPS administration,8 minipigs developed symptoms such as skin cyanosis,elevated body temperature,and respiratory distress.The oxygenation index decreased to<300 mmHg.Chest CT scans showed diffuse pulmonary infiltrates.Histopathology revealed alveolar edema and hyaline membrane formation.Transmission electron microscopy demonstrated disruption of pulmonary blood-air barrier,depletion of lamellar bodies in type Ⅱ pneumocytes,inflammatory cell infiltration,and exudation of plasma proteins and fibrin.Compared with LPS 0 h,at LPS 8 h,the oxygenation index and arterial blood pH were significantly decreased(P<0.001),while blood lactic acid and serum potassium were significantly increased(P<0.05);serum calcium and base excess were significantly decreased(P<0.05),and the lung injury score based on HE-stained lung sections was significantly increased(P<0.01).Conclusion The porcine ARDS model established by continuous LPS injection can dynamically simulate the pathophysiological characteristics and typical pathological manifestations of clinical septic ARDS,making it an effective tool to study the pathogenesis,prevention,and treatment strategies of septic ARDS.

Juvenile idiopathic arthritis (JIA) is the most common condition of chronic rheumatic disease in children. JIA is an autoimmune or autoinflammatory disease, with unclear mechanism and limited treatment efficacy. Recent studies have found a number of alterations in gut microbiota and its metabolites in children with JIA, which are related to the development and progression of JIA. This review focuses on the influence of the gut microbiota and its metabolites on immune function and the intestinal mucosal barrier and discuss the key role of the gut-joint axis in the pathogenesis of JIA and emerging treatment methods based on gut microbiota and its metabolites. This review could help elucidate the pathogenesis of JIA and identify the potential therapeutic targets for the prevention and treatment of JIA.

The phase changes and quantity-quality transfer of 17 batches of Ostreae Concha(Ostrea rivularis) during the raw material-calcined decoction pieces-standard decoction process were analyzed. The content of calcium carbonate(CaCO_3), the main component, was determined by chemical titration, and the extract yield and transfer rate were calculated. The CaCO_3 content in the raw material, calcined decoction pieces, and standard decoction was 94.39%-98.80%, 95.03%-99.22%, and 84.58%-90.47%, respectively. The process of raw material to calcined decoction pieces showed the yield range of 96.85% to 98.55% and the CaCO_3 transfer rate range of 96.92% to 99.27%. The process of calcined decoction pieces to standard decoction showed the extract yield range of 2.86% to 5.48% and the CaCO_3 transfer rate range of 2.59% to 5.13%. The results of X-ray fluorescence(XRF) assay showed that the raw material, calcined decoction pieces, and standard decoction mainly contained Ca, Na, Mg, Si, Br, Cl, Al, Fe, Cr, Mn, and K. The chemometric results showed an increase in the relative content of Cr, Fe, and Si from raw material to calcined decoction pieces and an increase in the relative content of Mg, Al, Br, K, Cl, and Na from calcined decoction pieces to standard decoction. X-ray diffraction(XRD) was employed to establish XRD characteristic patterns of the raw material, calcined decoction pieces, and standard decoction. The XRD results showed that the main phase of all three was calcite, and no transformation of crystalline form or generation of new phase was observed. Fourier transform infrared spectroscopy(FTIR) was employed to establish the FTIR characteristic spectra of the raw material, calcined decoction pieces, and standard decoction. The FTIR results showed that the raw material had internal vibrations of O-H, C-H, C=O, C-O, and CO■ groups. Due to the loss of organic matter components after calcination, no information about the vibrations of C-H, C=O, and C-O groups was observed in the spectra of calcined decoction pieces and standard decoction. In summary, this study elucidated the quantity-quality transfer and phase changes in the raw material-calcined decoction pieces-standard decoction process by determining the CaCO_3 content, calculating the extract yield and transfer rate, and comparing the element changes, FTIR characteristic spectra, and XRD characteristic pattern. The results were reasonable and reliable, laying a foundation for the subsequent process research and quality control of the formula granules of calcined Ostreae Concha(O. rivularis Gould), and providing ideas and methods for the quality control of the whole process of raw material-decoction pieces-standard decoction-formula granules of Ostreae Concha and other testacean traditional Chinese medicine.
