RESUMEN
Objective To observe the effects of chemotherapy on nutritional status and quality of life in elderly patients aged 60 years and over with stage Ⅲ or Ⅳ non-small-cell lung cancer,who were unable to undergo molecular-targeted drug therapy according to genetic testing.Methods A total of 100 elderly patients with stage Ⅲ or Ⅳ non-small cell lung cancer were randomized into an observation group(n=50)and a control group(n=50).Patients in the observation group were treated with GP regimen(gemcitabine+ cisplatin),while patients in the control group were treated with TP regimen(paclitaxel+cisplatin).The scores of nutritionally relevant indicators and quality of life were compared between the two groups.Results After chemotherapy,the body weight,body mass index,plasma total protein,plasma albumin,and triglyceride concentrations were significantly lower in the GP regimen group than in the TP regimen group(P＜0.0001,P =0.0027,P =0.0305,P＜0.0001,P＜ 0.0001,respectively).The overall health status score,physical function,role function,and emotional function scores were higher in the GP group than in the TP group(P =0.0017,0.0044,0.0064,0.006,respectively) after chemotherapy.The scores of shortness of breath,insomnia,loss of appetite,constipation,and diarrhea were significantly lower in the GP group than in the TP group(P =0.0067,P ＜0.0001,P =0.0026,P =0.0066,P =0.0023).The clinical effective rate was significantly higher in GP regimen than in TP regimen(56.0％ vs 30.0％,x2 =6.90,P=0.009).The incidence of grade Ⅰ adverse reactions was higher in the observation group (54.0％,27/50 cases),and the incidences of grade Ⅱ,Ⅲ and Ⅳ adverse reactions were higher in the control group(36.0％,18/50 cases;24.0％,12/50 cases;and 24.0％,12/50 cases,respectively) (x2 =16.40,P =0.001).Conclusions The TP chemotherapy is more beneficial to patients' nutrition,while the GP chemotherapy can achieve both higher clinical efficacy and better quality of life.
RESUMEN
Purpose To discuss the feasibility of evaluating left ventricular systolic function in patients with acute anterior myocardial infarction (AAMI) with three-dimensional speckle tracking imaging (3D-STI). Materials and Methods Thirty AAMI patients were examined with 3D-STI technique in terms of left ventricular longitudinal strain (LS), radial strain (RS), circumferential strain (CS), area strain (AS), global longitudinal strain (GLS), global riadial strain (GRS), global circumferential strain (GCS) and global area strain (GAS). The results were compared with those of 30 healthy persons and the strain values in normal segments of those AAMI patients. The threshold, sensibility and specificity of those parameters in diagnosing myocardial infarction were analyzed. Results Compared with healthy group, LS reduced in 12 out of 17 segments (12/17), RS reduced in 10/17, CS in 9/17 and AS in 11/17;they mainly focused in the base segment, middle and apex of anterior wall, the base segment and the middle of anterior septal, the apex of aboral septal, and the middle segment, apex of the lateral wall. The GLS, GRS, GCS and GAS were all lower than those in healthy group (differences with statistic signiifcance:P<0.05). In AAMI patient, LS, RS, CS and AS in the infarcted segments were lower compared with those in the normal segments (differences with statistic signiifcance:P<0.05). ROC curve analysis showed that the sensitivity of LS, RS, CS and AS were 89.2%, 79.0%, 77.9%, 85.3%, respectively in the diagnosis of myocardial infarction, and the speciifcity were 65.8%, 71.0%, 66.9%and 92.3%, respectively. The sensitivity of the GLS, GRS, GCS and GAS were 91.2%, 74.0%, 68.9%, 85.3%, respectively in the diagnosis of myocardial infarction, and the speciifcity were 69.8%, 71.0%, 76.9%and 93.3%, respectively. Conclusion 3D-STI can detect the strain values of LV segments efficiently and accurately so as to discriminate normal and infracted segments, which provides a reliable measurement to evaluate the extent of the infarction of the patients with acute anterior wall myocardial infarction.
