RESUMO
Sonic hedgehog signaling pathway has a unique role in the process of renal fibrosis,while it is mainly expressed in the impaired renal tubular epithelial cells. Shh signaling pathway promotes the process of epithelial-mesenchymal transition and renal tubulointerstitial fibrosis. Shh signaling pathway ligand triggers cell proliferation in the pericyte,suggesting a possible role for this pathway in the regulation of cell cycle progression of myofibroblasts progenitors during the development of renal fibrosis. Shh protein can be expressed at the early stage of kidney injury,which indicates that Shh signaling pathway is involved in the tissue repair process after kidney injury at the early stage. The process of renal interstitial fibrosis related to signaling pathway is involved with signaling pathway and proteins,cytokines,extracellular matrix,complement and so on. This paper reviews the progress in the study of the relationship between Shh and renal interstitial fibrosis.
RESUMO
Objective Our retrospective study is aimed to compare the effect and the adverse reaction of TNP(paclitaxel liposome +nedaplatin +tegafur)and PF(fluorouracil +cisplatin)in the treatment of head and neck squamous cell carcinoma(SCCHN).Methods Clinical data of patients with SCCHN received treatment at our hospital from 2009 to 2014 was retrospectively analyzed .Patients were divided into PF group and TNP group according to the treatment prescription .The general data,clinical features,treatment and the adverse reactions of the two groups were compared .Results A total of 54 patients was retrospective analyzed ,including 27 patients in TNP group and 27 in PF group.There was no significant differences in clinical data between the two groups .There was no significant differences in the location of the tumor ,clinical stage and differentiation degree between the two groups.The curative effect of TNP group was significantly ameliorated than the PF group .The incidence of gastro-intestinal reaction in TNP group was obviously lower than in PF group .There was no significant differences in the other adverse reactions .Conclusion In the treatment of SCCHN , TNP regimen is more effective than PF regi-men,and the incidence of gastrointestinal adverse reaction during the treatment is lower .
RESUMO
Objective To analyze the initial response rate of radiotherapy and chemotherapy,and the influence of different treatment modalities on pmgnnsis of primary non-Hodgkin lymphoma(NHL)of the nascl cavity.Methods From January 1993 to December 2002,70 patients were confirmed by histopathology as NHL,including 52 T cell origin,2 B cell and 16 NK cell.The main radiotherapy portal was set in front of the nose with a spade like protrusion,supplement with a portal next to the ear on one side or both sides.Combined portal in facial cervical area was first used when there was invasion of the oropharynx.The median dose to the nasal cavity wag 54.0 Gy with a range of 336 to 66 Gy,given before or during after radiotherapy or alone,consisted of 2-6 cycles chemotherapy of COP,CHOP or COBDP.Prognostic factors were analyzed with Cox model. Results The local control rates was 12.5%, 66.7% and 74.0% in chemotherapy alone,radiotherapy alone,and chemotherapy plus radiotherapy.The 5-year survival rate Wag 12.5%,50.0% and 62.0%,respectively(P＜0.05).Multifaetor analysis showed that tumor extension and treatment methods were the most important prognostic factors besides Ann-Arbor stage,but gender,pathology,age and symptoms had little effect on prognosis.Conclusion Chemotherapy plus radiotherapy group achieved a better survival rate than radiotherapy alone.For some NHL patients with good financial condition,APBSCT is a good choice.
