Forty-eight female Wistar rats were randomly divided into six groups (<em>n</em> = 8 each): normal control (NC), DEX (7 mg/kg, i.m.), NRG-low (NRG-L; 25 mg/kg, i.g.), NRG-medium (NRG-M; 50 mg/kg, i.g.), NRG-high (NRG-H; 100 mg/kg, i.g.), and alendronate (ALN; 0.25 mg/d, i.g.) groups. OP was induced by administering DEX once a week for five weeks in all groups except NC group. Begining in the third week after the initial DEX administration, the rats in NRG-L, NRG-M, NRG-H, and ALN groups received the corresponding treatments daily for three weeks, while NC and DEX groups received no additional treatment.

In rats administered with 25, 50, and 100 mg/kg NRG, there was a significant enhancement in serum biochemical indices, characterized by a reduction in tartrate-resistant acid phosphatase (TRAP), parathyroid hormone (PTH), and an elevation in osteocalcin (OC) and CT levels (<em>P</em> < 0.05, <em>P</em> < 0.01, and <em>P</em> < 0.001, respectively). Despite no significant changes in thickness, weight, and length (<em>P</em> > 0.05), there was a marked increase in bone mineral density (BMD) (<em>P</em> < 0.01, <em>P</em> < 0.001, and <em>P</em> < 0.001, respectively). Antioxidant enzyme markers showed significant upregulation, with higher glutathione, superoxide dismutase, and catalase, and a concurrent decrease in malondialdehyde (MDA) (<em>P</em> < 0.05, <em>P</em> < 0.01, and <em>P</em> < 0.001, respectively). The lipid profile also improved significantly, with lower cholesterol (CH), triglycerides (TG), and low-density lipoprotein (LDL) levels, and an increase in high-density lipoprotein (HDL) level (<em>P</em> < 0.05, <em>P</em> < 0.01, and <em>P</em> < 0.001, respectively). Inflammatory cytokine levels were reduced, as evidenced by decreases in tumor necrosis factor (TNF), interleukin (IL)-6, and IL-1<em>β</em> (<em>P</em> < 0.05, <em>P</em> < 0.01, and <em>P</em> < 0.001, respectively).

After data standardization and cleaning, we obtained 255 relevant medical records of Yang jaundice and Yang-Yin jaundice.

This study used precision, F1 score, the area under the receiver operating characteristic (ROC) curve (AUC), and accuracy as model evaluation metrics.

All groups except control group were injected once via the tail vein with streptozotocin (STZ, 38 mg/kg) combined with 28 d of chronic unpredictable mild stress (CUMS) to establish diabetic rat models with depression. During the CUMS modeling period, treatments were administered via gavage, with control and model groups receiving an equivalent volume of distilled water for 28 d. The efficacy of ZJJF in reducing blood sugar and alleviating depression was evaluated by measuring fasting blood glucose, insulin, and glycated hemoglobin levels, along with behavioral assessments, including the open field test (OFT), forced swim test (FST), and sucrose preference test (SPT). Hippocampal tissue damage and neuronal apoptosis were evaluated using hematoxylin-eosin (HE) staining and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) staining.

We obtained tongue images from patients with benign lung nodules and lung cancer using the TFDA-1 digital tongue diagnosis instrument, and analyzed these images with the TDAS V2.0 software. The extracted indicators included color space parameters in the Lab system for both the tongue body (TB) and tongue coating (TC) (TB/TC-L, TB/TC-a, and TB/TC-b), textural parameters [TB/TC-contrast (CON), TB/TC-angular second moment (ASM), TB/TC-entropy (ENT), and TB/TC-MEAN], as well as TC parameters (perAll and perPart). The bivariate correlation of TB and TC features was analyzed using Pearson’s or Spearman’s correlation analysis, and the overall correlation was analyzed using canonical correlation analysis (CCA).</div></div><div><h3>Results</h3><div>Samples from 307 patients with benign lung nodules and 276 lung cancer patients were included after excluding outliers and extreme values. Simple correlation analysis indicated that the correlation of TB-L with TC-L, TB-b with TC-b, and TB-b with perAll in lung cancer group was higher than that in benign nodules group. Moreover, the correlation of TB-a with TC-a, TB-a with perAll, and the texture parameters of the TB (TB-CON, TB-ASM, TB-ENT, and TB-MEAN) with the texture parameters of the TC (TC-CON, TC-ASM, TC-ENT, and TC-MEAN) in benign nodules group was higher than lung cancer group. CCA further demonstrated a strong correlation between the TB and TC parameters in lung cancer group, with the first and second pairs of typical variables in benign nodules and lung cancer groups indicating correlation coefficients of 0.918 and 0.817 (<em>P</em> &lt; 0.05), and 0.940 and 0.822 (<em>P</em> &lt; 0.05), respectively.</div></div><div><h3>Conclusion</h3><div>Benign lung nodules and lung cancer patients exhibited differences in correlation in the L, a, and b values of the TB and TC, as well as the perAll value of the TC, and the texture parameters (TB/TC-CON, TB/TC-ASM, TB/TC-ENT, and TB/TC-MEAN) between the TB and TC. Additionally, there were differences in the overall correlation of the TB and TC between the two groups. Objective tongue diagnosis indicators can effectively assist in the diagnosis of benign lung nodules and lung cancer, thereby providing a scientific basis for the early detection, diagnosis, and treatment of lung cancer.</div></div>","PeriodicalId":33578,"journal":{"name":"Digital Chinese Medicine","volume":"7 2","pages":"Pages 120-128"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142572374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
