ABSTRACT
Objective To explore the clinical effect of precise radiotherapy in the treatment of cancer in elderly patients. Methods We selected 88 elderly patients with advanced cancer at our hospital from January 2012 to December 2015.The patients were assigned into a control group(n＝44) treated with conventional radiation therapy and an intervention group (n＝44)receiving precise radiation therapy.Clinical effects and treatment reactions and adverse events were compared between the two groups. Results The total effective rate was higher in the intervention group than in the control group ,but the difference was not significant [40.9%(18/44)vs 56.8%(25/44) ,χ2＝ 2.228 ,P ＝0.135] .The control rate of clinical diseases was higher in the intervention group [77.3%(34/44)]than in control group[56.8%(25/44)](χ2＝ 4.166 ,P＝ 0.041).The incidence of adverse reactions was significantly lower in the intervention group [43.2%(19/44 )] than in the control group [68.2%(30/44)] ,(χ2＝ 5.572 ,P ＝ 0.018 ). Conclusions Precise radiotherapy has a precisely clinical efficacy and a lower incidence of adverse events. It is worth recommending and generalizing.
ABSTRACT
Sphincter of Oddi dysfunction (SOD)is a functional gastrointestinal disorder manifesting with the main symptoms of abdominal pain,abnormal liver function and recurrent idiopathic acute pancreatitis,which involved the abnormal contraction of sphincter of Oddi. The incidence of SOD has been increasing in recent years. More attention should be paid on SOD for decreasing the misdiagnosis in clinical practice. This article reviewed the recent advances in diagnosis and treatment of SOD.
ABSTRACT
The etiology and pathogenesis of irritable bowel syndrome (IBS) are not fully understood, and intestinal microbiota had been assumed as a possible factor in the pathogenesis of IBS.Increasing evidences have shown that alterations of gut microbiota were found in IBS patients and modulation of intestinal microbiota might be effective in the treatment of IBS.This article reviewed the mechanism of involvement of intestinal microbiota in pathogenesis of IBS by altering mucosal permeability, activating immune reaction, disturbing gastrointestinal motility and affecting brain-gut axis.
