ABSTRACT
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.
ABSTRACT
Objective To explore the application value of real-time shear wave elastography (SWE) technique in diagnosing and staging of chronic viral hepatitis B and hepatic fibrosis and to establish Young's modulus reference range for diagnosing and staging of hepatic fibrosis.Methods Forty-eight patients with chronic hepatitis B and fifty-eight healthy adults were enrolled and their Young's modulus values of S5 and S6 segments of liver were measured.Histopathologic examination was performed on 48 patients with chronic hepatitis B.Comparative analysis was conducted between the pathological findings and Young's modulus values,by means of which Young's modulus reference range for diagnosis and staging of hepatic fibrosis was obtained.Results There was significant difference in Young's modulus values of S5 and S6 segments of liver between chronic hepatitis B group and the normal control group (P＜0.05).Young's modulus values of S5 and S6 segments of liver in chronic hepatitis B group were (11.7 ± 2.9) kPa and (12.1 ± 3.2) kPa respectively,which were significantly higher than those in the normal control group,(5.7 ± 1.1) kPa and (5.8 ± 1.3) kPa respectively.Significant differences of Young's modulus values were detected in every staging of hepatic fibrosis (P＜0.05).S5 segment of liver Young's modulus values in S0-S4 stages were (5.8 ± 2.2) kPa,(7.3 ± 1.9) kPa,(10.3 ± 2.8) kPa,(10.3 ± 2.8) kPa,and (25.3 ± 3.6) kPa,respectively.S6 segment of liver Young's modulus values in S0-S4 stages were (5.7 ± 2.3) kPa,(9.2±2.1) kPa,(10.5±2.1) kPa,(14.7±4.5) kPa,and (26.1 ±2.1) kPa,respectively.Young's modulus value of the liver rose with the increase of S stage.Conclusion SWE technique can establish the Young's modulus reference range for hepatic fibrosis stage.Besides,it features high sensitivity,specificity and accuracy.
ABSTRACT
Objective To discuss the correlation between nutritional megaloblastic anemia and homocysteine,in order that e-valuate the application of homocysteine in some aspects that detection and treatment of megaloblatic anemia.Methods The study was divided into three groups,included case group (MA group,n=192,including megaloblatic anemia of vitamin B12 deficiency,n=60;megaloblatic anemia of folic acid deficiency,n=69;megaloblatic anemia of folic acid and vitamin B12 defi-ciency,n=63),matched group (heathy persons,n=200)and treated group (persons who recovered from megaloblatic ane-mia,n=192).Results The difference on homolevel in plasma between case group and matched group had statistical sidnifi-cance (t=3.56,3.21,2.78,P 0.05).The Hcy levels of folic acid deficiency vitamin B12 de-ficiency,vitamin B12 deficiency and folic acid and vitamin B12 deficiency had no statistical sidnificance (t=1.42,P >0.05). Conclusion The homocysteine level of patients who had nutritional megaloblatic anemia higher than heathy persons.High level of homocysteine had correction between the nutritional megaloblatic anemia.The lack of some nutrition facters (eg:fo-lic acid,vitamin B12)can lead to high homocysteine disease.Detecting the change of homocysteine level in plasma can guide the treatment of nutritional megaloblatic anemia.
ABSTRACT
@#Objective To study and evaluate the ability of allogeneic bone marrow stromal cells(BMSCs) to survive and regenerate bone in muscles without using immunosuppressive agents. Methods A complete mismatch between donor BMSCs and recipient rabbit was confirmed by one way mixed lymphocyte reaction assaysprior to implantation. And then bone marrow aspirates were obtained from donor rabbits.BMSCs were isolated from the bone marrow, cultured in conditional medium to be ubdyced to become osteogenic, and then to examine these characteristics. After that the donor BMSCs were transplanted into the recipient rabbits. Immunological tests such as lymphocyte transformation rate and cell mediated cytotoxity, histological observation, seeding cells survival and bone formation were performed following transplantation. Results Allogeneic BMSCs transplantation did not actually elicit an adverse immune response, and bone regenerated at the transplantation area, and then the transplanted BMSCs marked with BRDU preoperatively were founded to be living 8 weeks later after transplantation using immunohistochemistric technique. Conclusion Allogeneic BMSCs would not elicit an adverse immune response in vivo without the immunosuppressive therapy, which could survive and form new bone tissue with the help of BMP-2 in the muscles.
