Objective: To explore the main characteristics of syndromes in traditional Chinese medicine (TCM) in post-stroke depression (PSD) and to provide basis for treatments with TCM herbs. Methods: According to diagnostic criteria of PSD, stroke patients and depression patients from Department of Neurology, First Affiliated Hospital, Anhui University of Traditional Chinese Medicine were assigned into cerebral stroke group (150 cases), depression group (151 cases) and PSD group (123 cases). Neuropsychological assessments and imaging and biochemical analyses were conducted. TCM syndrome differentiation for these diseases was performed. We also determined the characteristics of TCM syndromes of PSD, relative risk of the syndromes and their correlations with ages as well. Results: Scores of qi stagnation and blood stasis, liver qi depression, and transformation of fire due to qi stagnation in PSD group were significant higher than those in cerebral stroke group (P<0.05, P<0.01). In cerebral stroke group, majority of the patients displayed one syndrome, while in PSD and depression groups, the patients had three or more syndromes. Of these syndromes, the incidence rate of syndrome of liver qi depression complicated with transformation of fire due to qi stagnation or flaring of fire due to yin deficiency was high. The syndrome of liver qi depression occurred much more frequently in PSD group and depression group than in cerebral stroke group (P<0.05, P<0.01). The logistic regression analysis showed that the syndrome of qi stagnation and blood stasis had high relative risk to PSD. The syndrome of deficiency of heart and spleen was positively correlated with age in cerebral stroke group. Conclusion: The main TCM syndromes of PSD and depression are qi stagnation and blood stasis, liver qi depression, and transformation of fire due to qi stagnation. The syndrome of deficiency of heart and spleen is closely related to age among the stroke patients. The syndrome of qi stagnation and blood stasis serves as an independent risk factor for PSD. The more complicated the syndromes are, the more serious depression becomes.

Genomic studies of cancer cell alterations,such as mutations,copy number variations(CNVs),and translocations,greatly promote our understanding of the genesis and development of cancers.However,the 3D genome architecture of cancers remains less studied due to the complexity of cancer genomes and technical difficulties.To explore the 3D genome structure in clin-ical lung cancer,we performed Hi-C experiments using paired normal and tumor cells harvested from patients with lung cancer,combining with RNA sequenceing analysis.We demonstrated the feasibility of studying 3D genome of clinical lung cancer samples with a small number of cells(1×104),compared the genome architecture between clinical samples and cell lines of lung cancer,and identified conserved and changed spatial chromatin structures between normal and cancer sam-ples.We also showed that Hi-C data can be used to infer CNVs and point mutations in cancer.By integrating those different types of cancer alterations,we showed significant associations between CNVs,3D genome,and gene expression.We propose that 3D genome mediates the effects of cancer genomic alterations on gene expression through altering regulatory chromatin structures.Our study highlights the importance of analyzing 3D genomes of clinical cancer samples in addition to cancer cell lines and provides an integrative genomic analysis pipeline for future larger-scale studies in lung cancer and other cancers.
