Objective To analyze the clinical diagnostic value of whole-body bone imaging combined with serum N-terminal osteo-calcin(N-Osrteoc)and vascular endothelial growth factor receptor 2(VEGFR2)for evaluating bone metastasis in elderly patients with lung cancer.Methods General data of 100 elderly patients with lung cancer diagnozed for the first time at Tianjin Hospital between December 2021 and December 2023 were retrospectively collected.Based on the pathological results,the patients were separated into a lung cancer bone metastasis group of 42 cases and a lung cancer non-bone metastasis group of 58 cases.Serum N-Osrteoc and VEGFR2 levels were detected by using an enzyme-linked immunosorbent assay(ELISA).All patients underwent whole-body bone imaging using SPECT diagnostic equipment.Receiver operator characteristic(ROC)curve analysis was performed to determine the diagnostic value of serum N-Osrteoc,VEGFR2,and whole-body bone imaging for lung cancer bone metastasis.Furthermore,Kappa test was performed to analyze the consistency between different examination methods for diagnozing lung cancer bone metastasis and pathological diagnosis results.Results The serum N-Osrteoc and VEGFR2 levels in the bone metastasis group were significantly higher than those in the non-bone metastasis group(P＜0.05).The area under the curve(AUC)for serum N-Osrteoc and VEGFR2 levels,whole-body bone imaging,and their combination for diagnozing lung cancer bone metastasis were 0.847,0.846,0.907,and 0.956,respectively.Furthermore,com-pared with the pathological results,the numbers of false-positive cases were 14,19,8,and 1,those of false-negative cases were 7,7,2,and 3,and the Kappa values were 0.579,0.487,0.799,and 0.917,respectively(P＜0.05).The specificity of whole-body bone imaging combined with serum N-Osrteoc and VEGFR2 in diagnozing lung cancer bone metastasis was significantly higher than alone(P＜0.05).Conclusion The combination of whole-body bone imaging and serum N-Osrteoc and VEGFR2 levels is of great significance for early diagnosis of bone metastasis in elderly patients with lung cancer.This combined diagnosis has high sensitivity and specificity and can be widely used in clinical practice.

AIM:To observe the effects of Huazhuo granules on phosphatidylinositol 3-kinase(PI3K)/protein kinase B(PKB/Akt)/glycogen synthase kinase-3β(GSK-3β)and PI3K/Akt/forkhead box protein O1(FOXO1)signaling pathways in the liver tissue of type 2 diabetes mellitus(T2DM)rats,and to explore its mechanism of action in regulating glycogen synthesis and gluconeogenesis.METHODS:Thirty 8-week-old SPF-grade male SD rats were chosen,with 5 ran-domly selected ones as the blank control group.The remaining 25 rats were fed to a high-sugar and high-fat diet for 4 weeks,followed by a single intraperitoneal injection of streptozotocin to establish a T2DM rat model.After successful mod-eling,these rats were randomly divided into 5 additional groups:the model group,a positive control group treated with met-formin,and low,medium,and high-dose Huazhuo granule groups,resulting in a total of 6 groups with 5 rats in each.Rats in the treatment groups were gavaged with the corresponding doses of medication,while those in the blank control and model groups were gavaged with an equal volume of saline once daily for 4 consecutive weeks.After 24-hour fasting with free access to water,the rats were euthanized to measure blood glucose,serum insulin levels,and serum triglyceride(TG),total cholesterol(T-CHO),high-density lipoprotein cholesterol(HDL-C),aspartate aminotransferase(AST)and alanine aminotransferase(ALT)levels.Liver pathological morphology was assessed by hematoxylin-eosin staining,and liver glycogen storage was detected by periodic acid-Schiff staining.Immunohistochemistry and Western blot analysis were employed to detect the protein levels of p-PI3K,p-Akt,p-FOXO1 and p-GSK-3β in the liver of rats in each group.The mRNA levels of phosphoenolpyruvate carboxykinase(PEPCK),glucose-6-phosphatase(G6Pase),GSK-3β,FOXO1,PI3K and Akt in liver tissues were detected by RT-qPCR.RESULTS:Compared with the model group,the rats in the high-dose Huazhuo Granule group and the metformin group exhibited decreased blood glucose and insulin levels(P<0.01),reduced AST,ALT,TG,and T-CHO concentrations(P<0.01),and increased HDL-C concentrations(P<0.01).The phosphorylation levels of PI3K,Akt,FOXO1,and GSK-3β proteins were up-regulated(P<0.01).In con-trast,the gene expressions of G6Pase,PERCK,FOXO1,and GSK-3β were all down-regulated(P<0.01).Conversely,the gene expressions of PI3K and Akt were upregulated(P<0.01).Pathological morphology of the liver tissue improved,accompanied by increased glycogen deposition in hepatocytes.CONCLUSION:Huazhuo granule manifests effects in lowering blood glucose and serum insulin levels,ameliorating blood lipids,and enhancing liver function in rats.These ef-fects are revealed to increase glycogen synthesis by activating the PI3K/Akt/GSK-3β signaling pathway and reduce gluco-neogenesis by activating the PI3K/Akt/FOXO1 signaling pathway.

Objective:To investigate the mechanism by which histone deacetylase 6 (HDAC6) exerts immune protective effects in Chlamydia trachomatis respiratory tract infection. Methods:Wild-type (WT) C57BL/6 mice and HDAC6 gene knockout (HDAC6 -/-) mice were used to establish mouse models of Chlamydia muridarum ( Cm) respiratory infection by nasal inhalation of Cm. qPCR and Western blot were used to detect the relative expression of HDAC6 in lung tissues of WT mice after Cm infection. Intracellular factor staining was used to detect the percentages and absolute numbers of CD4 + T cell subsets (Th1, Th17 and Th2 cells)in mouse lung tissues after infection. The levels of IL-4 in spleen cell culture supernatants were measured by ELISA. One-way or two-way analysis of variance (ANOVA) was used for statistical analysis. Results:Cm respiratory tract infection significantly promoted the expression of HDAC6 at both mRNA and protein levels in lung tissues of WT mice ( P<0.001). HDAC6 -/- mice lost more weight than WT mice and took longer to recover to the normal level. Chlamydia load ( P<0.001 and P<0.05) and pathological damage ( P<0.05 and P<0.000 1) in lung tissues were more serious in HDAC6 -/- mice than in WT mice at 7 and 14 d after infection. Neither the percentage nor the absolute number of Th1 (CD4 + IFN-γ + T) and Th17 (CD4 + IL-17 + T) cells showed significant differences between WT and HDAC6 -/- mice, while the percentage and absolute number of Th2 (CD4 + IL-4 + T) cells increased in HDAC6 -/- mice ( P<0.05 and P<0.01). Moreover, in HDAC6 -/- mice, the expression of IL-4 mRNA increased ( P<0.000 1) and the level of IL-4 in the splenic cell culture supernatants increased ( P<0.01). Conclusions:HDAC6 plays an immune protective role in Cm infection. It can reduce the susceptibility of host to Cm respiratory tract infection and alleviates the pathological damage in lung tissues by inhibiting the immune response of Th2 cells.

OBJECTIVE: To identify the key features of facial and tongue images associated with anemia in female populations, establish anemia risk-screening models, and evaluate their performance. METHODS: A total of 533 female participants (anemic and healthy) were recruited from Shuguang Hospital. Facial and tongue images were collected using the TFDA-1 tongue and face diagnosis instrument. Color and texture features from various parts of facial and tongue images were extracted using Face Diagnosis Analysis System (FDAS) and Tongue Diagnosis Analysis System version 2.0 (TDAS v2.0). Least Absolute Shrinkage and Selection Operator (LASSO) regression was used for feature selection. Ten machine learning models and one deep learning model (ResNet50V2 + Conv1D) were developed and evaluated. RESULTS: Anemic women showed lower a-values, higher L- and b-values across all age groups. Texture features analysis showed that women aged 30-39 with anemia had higher angular second moment (ASM)and lower entropy (ENT) values in facial images, while those aged 40-49 had lower contrast (CON), ENT, and MEAN values in tongue images but higher ASM. Anemic women exhibited age-related trends similar to healthy women, with decreasing L-values and increasing a-, b-, and ASM-values. LASSO identified 19 key features from 62. Among classifiers, the Artificial Neural Network (ANN) model achieved the best performance [area under the curve (AUC): 0.849, accuracy: 0.781]. The ResNet50V2 model achieved comparable results [AUC: 0.846, accuracy: 0.818]. CONCLUSION Differences in facial and tongue images suggest that color and texture features can serve as potential TCM phenotype and auxiliary diagnostic indicators for female anemia.
