The target of rapamycin ( TOR) , a Ser/Thr protein kinase of PIKKs ( phosphatidylinositol kinase-related kinases ) , is the central factor of a highly conserved signaling pathway in eukaryotes , and regulates cell growth in response to nutrients , hor-mones, and stresses.It controls temporal growth by activating anabolic processes such as translation , ribosome biogenesis , protein syn-thesis, transportation of amino acid and metabolic enzymes .The advances in TOR pathway in the most pervasive human fungal patho-gen Candida albicans.

Hepatotoxicity is one of the most common adverse reactions during anti -hyperlipidemia treatment .Mechanisms of anti-hyperlipidemia drug-induced hepatotoxicity are not clear yet , but most of the toxic reactions are dose-related hypersensitivity and could be released after drug withdrawal .It is accepted that clinical risk factors for the development of hepatotoxicity during anti -hyper-lipidemia treatment are high age and chronic illnesses .Treatment of anti-hyperlipidemia drug-induced hepatotoxicity has not been uni-fied and most of the treatments are non-specific and symptomatic .Researching hypotoxicity and hepatoprotection antihyperlipidemia drug, especially TCM and pharmaceutics will become a promising direction .

Objective To investigate the effect of medical sodium hyaluronate gel (HA) on the growth and metastasis of abdominal and pelvic tumor cells in vitro and in nude mice. Methods Three tumor cells, Hela, CT26 and HCT116, were used to investigate the effects of different HA concentrations on the growth and migration of tumor cells in vitro by MTT assay and Transwell assay. An orthotopic transplantation model of colonic tumor in nude mice was established to investigate the effect on the proliferation of cell HCT116 by comparing the tumor volume and tumor mass 4 weeks after inoculation. The effects on the metastasis of cell CT26 were investigated by comparing the tumor metastasis rate and the number of metastatic lesions of lung and liver in nude mice among the different experimental groups 3 weeks after inoculation. Results HA did not promote the growth and metastasis of Hela, CT26 and HCT116 cells in vitro at different concentrations. Actually, HA exhibited a certain inhibitory activity at the concentration of 5 mg/ml. In the orthotopic transplantation model of colonic tumor-HCT116, HA did not promote the growth of cell HCT116. In the orthotopic transplantation model of colonic tumor-CT26, HA inhibited CT26 tumor metastasis. Conclusion Under the experimental conditions, HA did not promote the growth, migration or metastasis of abdominal and pelvic related tumor cells including Hela, CT26 and HCT116 in vitro and in vivo.

Objective To summary the hospitalization costs of lung cancer patients, and analyze the influence factors in these patients, and provide basis for controlling hospitalization costs of lung cancer patients. Methods The hospitalization costs data of hospitalized lung cancer cases in Wuhan from 2018 to 2020 were collected from medical records. Nonparametric test was used to analysis the data for single factor analysis. The patients were divided into two groups according on the upper quartile value of hospitalization cost, that is high-cost group (the cost ≥ the upper quartile value) and normal cost group (the cost “four major hospitals in Hubei^” respectively. The hospital type is an independent influencing factors, compared with specialized hospital, the OR is 4.726 for general hospital. The hospitalization days is the independent influencing factors, more hospitalization days has high cost. The treatment mode is the independent influencing factors, compared with non-operative treatment, the OR is 556.129, 18.156 and 5.212 for surgical model, radio therapy model and interventional model respectively. Conclusion The age, hospital level, hospital type, hospitalization days and treatment mode are the independent influencing factors of hospitalization costs. To reduce the hospitalization cost of lung cancer patients, we should standardize the diagnosis of lung cancer patients, and focus on standardizing the treatment mode, also considering other influencing factors, such as hospital level, hospital type.

Hyaluronic acid is widely present in the human body. It is an important component of extracellular matrix. It has unique hydrodynamic properties, good viscoelasticity and strain properties. At present, hyaluronic acid has been widely used in biomaterials, targeted-drug preparations, cosmetics and prevention of adhesion after abdominal surgery. With the expansion of the application scope of hyaluronic acid and the continuous emergence of new medical materials, the research on hyaluronic acid has been increasing in recent years. This paper reviews the clinical application of hyaluronic acid and its mechanism, in order to provide reference for the further development and safe application of hyaluronic acid products.
