[Objective] To determine the correlation between traditional Chinese medicine (TCM) inspection of spirit classification and the severity grade of depression based on facial features, offering insights for intelligent intergrated TCM and western medicine diagnosis of depression. [Methods] Using the Audio-Visual Emotion Challenge and Workshop (AVEC 2014) public dataset on depression, which conclude 150 interview videos, the samples were classified according to the TCM inspection of spirit classification: Deshen (得神, presence of spirit), Shaoshen (少神, insufficiency of spirit), and Shenluan (神乱, confusion of spirit). Meanwhile, based on Beck Depression Inventory-II (BDI-II) score for the severity grade of depression, the samples were divided into minimal (0 – 13, Q1), mild (14 – 19, Q2), moderate (20 – 28, Q3), and severe (29 – 63, Q4). Sixty-eight landmarks were extracted with a ResNet-50 network, and the feature extracion mode was stadardized. Random forest and support vectior machine (SVM) classifiers were used to predict TCM inspection of spirit classification and the severity grade of depression, respectively. A Chi-square test and Apriori association rule mining were then applied to quantify and explore the relationships. [Results] The analysis revealed a statistically significant and moderately strong association between TCM spirit classification and the severity grade of depression, as confirmed by a Chi-square test (χ2 = 14.04, P = 0.029) with a Cramer’s V effect size of 0.243. Further exploration using association rule mining identified the most compelling rule: “moderate depression (Q3) → Shenluan”. This rule demonstrated a support level of 5%, indicating this specific co-occurrence was present in 5% of the cohort. Crucially, it achieved a high Confidence of 86%, meaning that among patients diagnosed with Q3, 86% exhibited the Shenluan pattern according to TCM assessment. The substantial Lift of 2.37 signifies that the observed likelihood of Shenluan manifesting in Q3 patients is 2.37 times higher than would be expected by chance if these states were independent—compelling evidence of a highly non-random association. Consequently, Shenluan emerges as a distinct and core TCM diagnostic manifestation strongly linked to Q3, forming a clinically significant phenotype within this patient subgroup. [Conclusion] Automated facial analysis can serve as a common lens for TCM and western psychological assessments align in the diagnosis of depression. The inspection of spirit decline trajectory parallels worsening depression, supporting early screening and stratified intervention, and providing a reference for the intelligent assistance of integrated TCM and western medicine in the diagnosis of depression.

Secondary lymphedema is a chronic progressive disease caused by the obstruction of lymphatic reflux, which leads to a series of secondary affection. There is no cure at present. Exploring the pathogenesis and treatment of lymphedema is based on animal models that mimic the pathophysiology of chronic lymphedema in humans. Currently, there are many known animal models of lymphedema, such as the limb lymphedema model of mice, dogs and other animals, and the rabbit ear lymphedema model. But most of them cannot induce the persistent and stable lymphedema temporarily, which lead to a deadlock in the related research progress. Therefore, it is necessary to improve and even create new animal models of lymphedema. This paper summarises the progress of relevant literature and provides references for further improving the establishment of a lymphedema animal model. It also summarise existing methods for evaluating lymphedema or lymphatic vessel function to provide an evaluation tool for modified or new animal models.

Advances in high-throughput sequencing (HTS) have fostered rapid developments in the field of microbiome research, and massive microbiome datasets are now being generated. However, the diversity of software tools and the complexity of analysis pipelines make it difficult to access this field. Here, we systematically summarize the advantages and limitations of microbiome methods. Then, we recommend specific pipelines for amplicon and metagenomic analyses, and describe commonly-used software and databases, to help researchers select the appropriate tools. Furthermore, we introduce statistical and visualization methods suitable for microbiome analysis, including alpha- and beta-diversity, taxonomic composition, difference comparisons, correlation, networks, machine learning, evolution, source tracing, and common visualization styles to help researchers make informed choices. Finally, a step-by-step reproducible analysis guide is introduced. We hope this review will allow researchers to carry out data analysis more effectively and to quickly select the appropriate tools in order to efficiently mine the biological significance behind the data.

Objective: To analyze perioperative serum high mobility group box-1 protein (HMGB1) levels in patients with acute cholangitis and its clinical significance. Methods: 118 cases of choledocholithiasis with acute cholangitis were retrospectively analyzed, admittd in Minhang Hospital from Jan 2017 to Dec 2017. Enzyme linked immunosorbent assay (ELISA) was used to detect serum HMGB1 levels before and after ERCP. The relationship between serum HMGB1 levels and severity of the disease was analyzed. Results: The serum HMGB1 levels in the healthy controls, mild cholangitis group, moderate cholangitis group and severe cholangitis group were(1.74±0.79) μg/L, (9.19±4.86) μg/L, (12.62±4.13) μg/L, (18.02±3.84) μg/L, respectively. The serum HMGB1 levels were significantly different in these four groups (F=63.348, P<0.05). The serum HMGB1 levels in the three groups after ERCP were significantly lower than those before ERCP(t=10.978, t=35.682, t=42.649; P<0.05). The serum HMGB1 levels were positively correlated with WBC, CRP, total bilirubin, direct bilirubin and alanine aminotransferase. Conclusion Serum HMGB1 levels were significantly higher in patients with acute cholangitis, and the more serious the disease, the higher the HMGB1 levels. After ERCP, serum HMGB1 levels were significantly lower than before. HMGB1 is an effective parameter for evaluating the severity of acute cholangitis.

BACKGROUNDNumerous previous studies have shown that renal insufficiency (RI) in patients with acute coronary syndrome is associated with poor cardiovascular outcomes. These studies do not well address the impact of RI on the long-term outcome of patients with acute ST-elevation myocardial infarction (STEMI) in China. The aim of this study was to investigate the association of admission RI and inhospital and long-term mortality of patients with acute STEMI.

METHODSThis was a multicenter, observational, prospective-cohort study. 718 consecutive patients were admitted to 19 hospitals in Beijing within 24 hours of onset of STEMI, between January 1,2006 and December 31,2006. Estimation of glomerular filtration rate (eGFR) was calculated using the modified abbreviated modification of diet in renal disease equation-based on the Chinese chronic kidney disease patients. The patients were categorized according to eGFR, as normal renal dysfunction (eGFR ≥ 90 ml·min -1·1.73 m -2 ), mild RI (60 ml·min -1·1.73 m -2 ≤ eGFR < 90 ml·min -1·1.73 m -2 ) and moderate or severe RI (eGFR < 60 ml·min -1·1.73 m -2 ). The association between RI and inhospital and 6-year mortality of was evaluated.

RESULTSSeven hundred and eighteen patients with STEMI were evaluated. There were 551 men and 167 women with a mean age of 61.0 ± 13.0 years. Two hundred and eighty patients (39.0%) had RI, in which 61 patients (8.5%) reached the level of moderate or severe RI. Patients with RI were more often female, elderly, hypertensive, and more patients had heart failure and stroke with higher killip class. Patients with RI were less likely to present with chest pain. The inhospital mortality (1.4% vs. 5.9% vs. 22.9%, P < 0.001), 6-year all-cause mortality (9.5% vs. 19.8 vs. 45.2%, P < 0.001) and 6-year cardiac mortality (2.9% vs. 12.2% vs. 23.8%, P < 0.001) were markedly increased in patients with RI. After adjusting for other confounding factors, classification of admission renal function was an independent predictor of inhospital mortality (Odd ratio, 1.966; 95% confidence interval [CI], 1.002-3.070, P = 0.019), 6-year all-cause mortality (relative risk [RR] = 1.501, 95% CI: 1.018-4.373, P = 0.039) and 6-year cardiac mortality (RR = 1.663, 95% CI: 1.122-4.617, P = 0.042).

CONCLUSIONSRI is very common in STEMI patients. RI evaluated by eGFR is an important independent predictor of short-term and long-term outcome in patients with acute STEMI.

The aim of this study was to investigate the feasibility of anterior segment optical coherence tomography to assess the anterior segment morphology of hyperopia in school-aged children. 320 eyes of 160 school-aged children, 6-12 years of age, were examined with anterior segment optical coherence tomography and were divided into four groups according to the cycloplegic spherical equivalence of refractive error. The mentioned four groups were: emmetropia group, low hyperopia group, moderate hyperopia group and high hyperopia group. The measurements of central corneal thickness, anterior chamber depth, angle opening distance, trabecular iris space area and scleral angle were compared in pairs among objects in the four groups. The results showed that high hyperopia and moderate hyperopia had shallower anterior chamber depth and narrower anterior chamber angle compared to those in emmetropia group. The study also showed that anterior segment optical coherence tomography as a non-contact technology could become a new technology for accessing the anterior segment morphology of hyperopia in school-aged children.
