Methods: Patients with dry eye who were treated in the Ophthalmology Ward and Outpatient Department of the First Hospital of Hunan University of Chinese Medicine from October 1, 2020, to October 30, 2021 were enrolled as the research participants in the study. They were assigned to two groups based on traditional Chinese medicine (TCM) syndrome types: heat stagnation in liver meridian pattern group and Qi-Yin deficiency pattern group. Healthy volunteers who underwent health check-ups in the Health Management Department were included as healthy group following the random number table method. The tears of the patients and the healthy volunteer participants were tested by high-performance liquid chromatography-mass spectrometry (LC-MS). The differential metabolites were screened out by multivariate statistical analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment was performed on the differential metabolites. Finally, the association analysis of differential proteins and metabolites was conducted to verify and supplement the metabolites. Results: A total of 32 dry eye patients were enrolled, including 16 cases with heat stagnation in liver meridian pattern and 16 cases with Qi-Yin deficiency pattern. Fourteen healthy volunteers were included as healthy group. There were no significant differences in baseline characteristics among the three groups (P > 0.05). A total of 412 biomarkers were determined in Qi-Yin deficiency pattern group, mainly including lipids, lipid-like molecules, organic acids and their derivatives, organic heterocyclic compounds, and nucleosides and their analogues. For heat stagnation in liver meridian pattern group, 112 metabolites were determined, mainly including organic acids and their derivatives, lipids, and lipid-like molecules. The KEGG enrichment results of pathways and the relative content analysis of differential markers demonstrate that purine metabolism and caffeine metabolism pathways are common metabolic characteristics of all dry eyes. Among them, deoxyinosine monophosphate (dIMP) and 2-(formamido)-N1-(5-phospha-D-ribosyl) acetamidine can serve as their biomarkers. The main characteristics of Qi-Yin deficiency syndrome pattern were the significant enhancement of metabolic pathways such as lysine degradation, ovarian steroidogenesis, cholesterol metabolism, pyrimidine metabolism, and bile secretion (P < 0.05). Dry eye associated with the heat stagnation in liver meridian pattern is mainly characterized by inhibition of the valine, leucine, and isoleucine biosynthesis pathways (P < 0.05). Conclusion Metabolomics can be used as an effective basis for TCM syndrome classification. Different patterns of dry eye syndrome exhibit typical characteristics in the types and concentrations of metabolites, which correspond to the syndrome classification in TCM. This study initially confirms the rationality of TCM syndrome classification and provides significant reference for the mechanism of dry eye and drug development.

Objective To explore the microstructural changes in white matter(WM)fibers of patients with post-stroke depression(PSD)by using automated fiber quantification(AFQ)and the relationship between changes in fibers and the Hamilton depression scale(HAMD).Methods The HAMD and MRI data were collected from stroke patients with a single anterior circulation infarction at 1-month follow-up.AFQ was used to extract the main fibers and calculate the fractional anisotropy(FA)of each node in each fiber.The difference of node FA in each fiber between groups and correlations between altered node FA and HAMD were then evaluated.Results Data were collected from 8 patients with PSD and 18 patients without PSD(non-PSD).Compared with that in non-PSD,the node FA in the callosum,left inferior longitudinal fasciculus,and uncinate fasciculus were significantly decreased in patients with PSD(P<0.05).The altered node FA values in the corpus callosum forceps minor(r=-0.418,P=0.047)and left uncinate fasciculus(r=-0.467,P=0.029)were negatively related to HAMD in patients with PSD.Conclusions AFQ can precisely measure the segmental microstructural damage of nerve fiber bundles in patients with PSD,of which segmental microstructural damage of the corpus callosum forceps and hook tracts is associated with the severity of depression.

Objective:To investigate the expression of fibrinogen-like protein 1 (FGL1) in clear cell renal cell carcinoma (ccRCC) and its correlation with clinicopathological characteristics of patients with ccRCC.Methods:The clinicopathological data of 242 patients with ccRCC who were diagnosed and treated surgically from January 2015 to December 2018 were retrospectively analyzed. The cancerous tissues and paracancerous tissues (2 cm away from the edge of cancerous tissues) of patients were collected. The expression of FGL1 protein was detected by using immunohistochemistry, and the relative expression level of FGL1 mRNA was detected by using reverse transcription polymerase chain reaction (RT-PCR). Cox proportional risk model was used to make univariate and multivariate analysis of the influencing factors of progression-free survival (PFS).Results:The positive rate of FGL1 protein in ccRCC tissues was higher than that in paracancerous tissues [28.5% (69/242) vs. 2.1% (5/242)], and the difference was statistically significant ( χ2 = 65.34, P < 0.001); the relative expression level of FGL1 mRNA in ccRCC tissues was higher than that in paracancerous tissues (1.67±0.12 vs. 0.60±0.15), and the difference was statistically significant ( t = 25.33, P < 0.001). The expression of FGL1 was positively correlated with pathological staging ( r = 0.164, P = 0.011), renal vascular tumor thrombus ( r = 0.130, P = 0.043), regional lymph node metastasis ( r = 0.153, P = 0.018), and distant metastasis ( r = 0.160, P = 0.012). Univariate analysis showed that the tumor diameter, regional lymph nodes metastasis, pathological staging, distant metastasis, and FGL1 expression were factors influencing the PFS of ccRCC patients (all P < 0.05). Multivariate regression results showed that high expression of FGL1 ( HR = 11.679, 95% CI 7.432-15.673, P = 0.015), pathological staging of Ⅲ-Ⅳ ( HR = 13.654, 95% CI 8.765-18.761, P = 0.013), and distant metastasis ( HR = 11.387, 95% CI 7.662-14.831, P = 0.038) were independent risk factors for PFS in patients. Conclusions:FGL1 is highly expressed in ccRCC, which is correlated with pathological staging, renal vascular tumor thrombus, regional lymph nodes metastasis, and distant metastasis. The high expression of FGL1 is a risk factor affecting the prognosis of patients with ccRCC.

Objective:To investigate the correlation between radiation dose of the pelvic bone marrow of different anatomical bony sites and the incidence of neutrophil toxicity during the three-dimensional radiotherapy concurrent chemotherapy for cervical cancer.Methods:Clinical data of 117 cervical cancer patients who received three-dimensional radiotherapy concurrent chemotherapy from 2016 to 2018 were retrospectively analyzed. The dosimetric parameters included D mean, V 5Gy, V 10Gy, V 20Gy, V 30Gy, V 40Gy and V 50Gy. The correlation between the dosimetric parameters and the lowest neutrophil count was analyzed by linear regression analysis. Clinicopathological features and dosimetric parameters were included into the multivariate regression analysis model. Results:The incidence rates of neutrophil toxicity (grade 1-4) were 10.3%, 27.4%, 11.1% and 10.3%, respectively. The linear regression analysis showed that the D mean and V 50Gy of lumbosacral vertebrae (LS), the D mean, V 5Gy, V 10Gy, V 20Gy, V 30Gy, V 40Gy and V 50Gy of the ilium were significantly correlated with the grade 2-4 neutrophil toxicity ( P=0.035、<0.001、<0.001、=0.001、=0.003、=0.001、<0.001、<0.001、<0.001). Multivariate analysis demonstrated that the V 20Gy, V 30Gy and V 50Gy of the LS, the D mean, V 5Gy, V 10Gy, V 20Gy and V 30Gy of the ilium were significantly correlated with the grade 2-4 neutrophil toxicity ( P=0.046、0.038、0.049、0.041、0.039、0.029、0.036、0.029). Conclusion:During the process of three-dimensional radiotherapy concurrent chemotherapy for cervical cancer, the volume of medium-and high-dose of LS and the volume of low-and medium-dose of ilium are significantly correlated with the risk of neutrophil toxicity.
