Liver cancer is one of the most common malignant tumors in the digestive system and ranks sixth among newly diagnosed malignant tumors worldwide. Transforming growth factor-β （TGF-β） regulates cell differentiation， proliferation， apoptosis， and other physiological and pathological mechanisms and exerts cancer-suppressive and pro-cancerous dual effects in the process of tumor development. In recent years， with the continuous exploration of the mechanism of liver cancer， it has been found that the conversion of the cancer-suppressive effect into a pro-cancerous effect of this pathway plays a key role in the development of liver cancer. Traditional Chinese medicine （TCM） provides a unique perspective for the classification， diagnosis， and treatment of liver cancer with its comprehensive regulatory effects of multi-components， multi-targets， and multi-pathways. This paper summarized that the cancer-suppressive mechanisms of the TGF-β signaling pathway included promoting cancer cell cycle arrest， apoptosis， autophagy， et al， while the pro-cancerous mechanisms included promoting cancer cell proliferation， invasion and metastasis， immunosuppression， angiogenesis， et al. The TCM compounds intervening this pathway were sorted out， including Jianpi Huayu compound， Fuyang Baoyuan compound， Yipi Yanggan compound， Fuzheng Jiedu compound， compound Astragalus and Salvia， Biejia Jianwan， Dahuang Zhechong pill， and Qingxiang powder. The single TCMs mainly included Schizocapsa plantaginea， Dendrobii Caulis， Gleditsia sinensis， and Dracaena cochinchinensis. The active ingredients of TCM are mainly concentrated on flavonoids， alkaloids， glycosides， phenolics， terpenoids， polysaccharides， and other kinds of compounds. At the same time， it summarized that the liver cancer inhibition mechanism of TCM by regulating this pathway mainly included promoting apoptosis of liver cancer cells， blocking the cell cycle， and inhibiting liver cancer cell proliferation， migration， invasion， angiogenesis， immune escape， etc. The mechanism aims to give full play to the advantages of TCM and precisely regulate the TGF-β signal， thereby exerting positive anti-tumor effects， opening up a new direction for the precise targeted treatment of liver cancer， and providing a scientific basis and a new strategy for the application of TCM in the treatment of liver cancer.

{L-End}Objective To investigate the current status of sleep quality and its influencing factors among coal miners in a company in Shanxi Province. {L-End}Methods A total of 1 047 coal miners from a coal mine company in Shanxi Province were selected as the study subjects by convenient sampling method. The occupational stress, occupational burnout and sleep quality of the study subjects were investigated using Occupational Stress Core Scale, Maslach Burnout Inventory-General Survey and Pittsburg Sleep Quality Index Scale. {L-End}Results The detection rates of occupational stress, occupational burnout, sleep disorder were 58.9%, 59.1% and 57.9%, respectively. The result of multivariate logistic regression analysis showed that education level, alcohol consumption, work shift, duration of dust-exposure, phase of respiratory symptoms, self-assessment of health, occupational stress and occupational burnout were independent influencing factors of sleep disorders in the coal miners (all P<0.05). Among them, the risk of sleep disorders in drinkers was higher than that in non-drinkers (P<0.05); the risk of sleep disorders was higher in miners working in a rotating work shift with two shifts than in those with three shifts (P<0.05); the higher the education level, the longer the duration of dust-exposure, the more serious the phase of respiratory symptoms, the worse the self-assessment of health, the higher the degree of occupational stress and the higher the degree of occupational burnout, the higher the risk of sleep disorders (all P<0.05). {L-End}Conclusion The incidence of sleep disorders in coal miners in this company is relatively high. Occupational stress, occupational burnout, education level, alcohol consumption, work shift, duration of dust-exposure, respiratory symptoms and health status are risk factors for sleep disorders in coal miners.

Objective:To explore the possible mechanism of astragaloside involved in the mouse podocytes injury induced by TGF-β1 in vitro.Methods:Mouse podocytes were cultured in vitro and then all cell were divided into 5 groups:normal control group , TGF-β1 treatment group ,TGF-β1 treatment +astragaloside low dose group ,TGF-β1 treatment +astragaloside middle dose group and TGF-β1 treatment +astragaloside high dose group.The proliferation rate of each group was investigated by MTT assay ,the expression of TRPC6 protein and mRNA were measured by Western blot and RT-PCR respectively after 48 hours.Results:TGF-β1 can significantly inhibit the proliferation of podocytes ( P<0.05) ,fusions of foot processes or even effaced of podocytes were observed .TGF-β1 could also increase the expression of TRPC6.Astragaloside could reduce the inhibition of TGF-β1 to the proliferain of podocytes significantly ,make the cell shape tend to be normal,and reduce the expression of TRPC6 mRNA and protein with dose-effect relation.Conclusion:TRPC6 play an impor-tant role in the TGF-β1 induecd podocytes injury .Astragaloside can alleviate podocytes injury by reduce the expression of TRPC 6.
