ABSTRACT
Ulcerative colitis(UC)is a common disease of the digestive system.Phosphatidylinositol-3-kinase(PI3K)/synuclein/threonine kinase(AKT)is closely related to cell survival,apoptosis,inflammation and other biological processes,and the expression levels of PI3K and AKT significantly increase during the course of UC,with accelerated apoptosis,improved inflammation,and damaged intestinal mucosal barrier function.In recent years,a large number of basic and clinical trials have been conducted on PI3K/AKT signaling pathway in TCM,and the results indicate that PI3K/AKT signaling pathway is expected to be an important potential target for UC treatment.This article analyzed the mechanism of the regulation of PI3K/AKT signaling pathway in TCM from monomer,extract,compound and acupuncture,and suggested that the regulation of this signaling pathway is of great significance for the prevention and treatment of UC,and provide reference for drug development.
ABSTRACT
[Objective] Summary of Ming and Qing Dynasties and traditional Chinese medicine before tumor disease, to clarify the concept and to separate the tumor, and the tumor gall. [Method] Carefully read the documents of ancient Chinese medicine literature, combined with the relevant theoretical research methods of TCM, analyze the etiology and pathogenesis of neoplasia and its diagnosis and treatment system, summarize the theoretical system of the disease. [Results] The tumor is between blood stasis and phlegm stagnation. In time, the flesh skin membrane, between flesh and skin, because of its clinical and gall disease shows the organism body mass, so the ancient medical books of the two are collectively referred to as the gall disease. It is equivalent to the surface soft tissue tumor of modern medicine. [Conclusion] Before and after Ming and Qing Dynasties, Chinese medicine has formed a complete system of diagnosis and treatment of tumor, which has a good guiding effect on modern clinic.
ABSTRACT
Objective To explore the pathological and clinical features of renal epithelioid angiomyolipoma (EAML). Methods From February 2001 to June 2010,4 cases of renal epithelioed angiomyolipoma (EAML) diagnosed in our unit were reviewed on their clinical and histopathological feathers retrospectively.The prognosis of renal EAML were evaluated according to the immunohistochemical findings.Of the 4 cases,the first case had a history of nodular sclerosis and presented a sign of hemorrage caused by the rupture of the tumor.The second case also showed a sign of hemorrage complicated with hemorrhagic shock.The third case had no symptom,but suffered from clear cell carinoma concomitantly on the other kidney.The fourth case came for consultation for his bilateral angiomyolipoma.All the 4 cases had fat composition founded in their CT scans. Results The first case was taken biopsy on the tumor of her right kidney,and lost of follow-up 6 months later.The second case undertaken radical nephrectomy,and no tumor recurrence detected after 10 months follow-up.The third case undertaken right nephron-sparing nephrectomy,and left nephron-sparing nephrectomy 6 months later.No recurrence detected during the follow-up 8 months later.Bilateral resection of the angiomyolipoma was performed on the fourth case,and a malignancy on the left kidney was deteceded 6 years later,then a radical nephrectomy was performed.But liver metastasis was founded half a year later during the follow-up.Immunohistochemcial staining of these tumors showed positive HMB45 and Melan-A but negative CK and EMA. Conclusions Renal EMAL has malignant potentiality,and the aggressiveness of it makes the close follow-up compulsive.Immunohistochemcial study is useful for diagnosis and differential diagnosis,even helpful to assess the prognosis.
