ABSTRACT
Objective To evaluate the effect of gastric compound on patients with middle-late gastric cancer of spleen deficiency and stasis toxin. Methods Ninety patients with middle-late gastric cancer of spleen deficiency and stasis toxin were randomly divided into combined group, chemotherapy group, and gastric compound group, 30 cases in each group. Patients in the combined group were treated with gastric compound and chemotherapy;patients in the chemotherapy group were treated with placebo;patients in the gastric compound group were treated with gastric compound. The changes of QLQ-C30 scale integral, fatigue scale intergral, TCM symptom intergral, Karnofsky integral, and toxic and side effects of digestive tract and myelosuppression were observed to evaluate the effect of gastric compound on quality of life in patients. Results The changes of QLQ-C30 scale integral, fatigue scale intergral, TCM symptom intergral, Karnofsky intergal in combined group were better than those in chemotherapy group and gastric compound group, with statistical significance (P<0.05). The changes of fatigue scale intergral and TCM symptom intergral in gastric compound group were better than those in chemotherapy group, with statistical significance (P<0.05). The myelosuppression and toxic and side effects of digestive tract of combined group was lighter than those of chemotherapy group, with statistical significance (P<0.01). Conclusion Gastric compound combined with chemotherapy can improve quality of life in patients with middle-late gastric cancer of spleen deficiency and stasis toxin, and reduce myelosuppression and toxic and side effects of digestive tract.
ABSTRACT
ObjectiveTo investigate the therapeutic effects of advanced lung adenocarcinoma treated with TCM treatment based on syndrome differentiation combined with Gefitinib.MethodsAll cases were recruited from adenocarcinoma of lung patients in Hunan Province Cancer Hospital from February 2008 to February 2010.These 56 adenocarcinoma of lung patients were randomly divided into a treatment group (30cases) and a control group (26 cases).The control group was treated with Gefitinib,250 mg/d,until the disease getting progress or the patient showing intolerable untoward reaction; while the treatment group was treated with TCM syndrome differentiation based on the control group.ResultsAfter the treatment,the total therapeutic effects was 90.00% in the treatment group than 65.38% in the control group (x2=5.40,P<0.05); symptoms score in both group decreased after the treatment,comparing with the same group before the treatment,with the difference was statistical significance (tthe treatment group=9.2446,tthe control group=2.7778,both P<0.01) ;non-progressive survival rate of half year,1year and 2year was 66.67%,50.00% and 30.00% respectively,and survival rate of lyear and 2yenr was 73.33% and 46.67% respectively,in the treatment group,while non-progressive survival rate of half year,lyear and 2year was 38.46%,23.08% and 7.69% respectively,and survival rate of 1year and 2year was 46.15% and 19.23% respectively,in the control group,showing statistical difference between the two groups (x2 value was 4.46、4.31、5.44、4.31、5.27,P value was 0.03、0.04、0.02、0.04、0.02,all P<0.05 ) ; the effective power of KPS was 76.67% and 46.15% in the treatment and the control group respectively,showing statistical difference(x2=6.24,P<0.05) ; both groups were absent of such side effects of hematology,heart,liver and kidney toxicity,and interstitial pneumonia,but the incidence rate of Ⅱ ~ Ⅲ degree rash and diarrhea was significantly decreased in the treatment group,comparing with the control group(x2=4.49、4.37,P<0.05 ).ConclusionThe therapy of TCM treatment based on syndrome differentiation combined with Gefitinib can improve living quality,control aggravation of disease,prolong life span and enhance survival rate of the patients with advanced lung adenocarcinoma.
ABSTRACT
Atomic force microscopy (AFM) has been applied in many biological investigations in recent years, and this review focuses on the application of AFM in DNA-protein interactions. AFM images of static DNA-protein complexes, in air and in liquid, can be used to obtain quantitative and qualitative information on the structure of different complexes. And dynamic AFM images of DNA-protein complexation in real time under liquid conditions will help to understand biological processes and mechanisms at single molecule level. In addition, the measurement of intermolecular forces between biomolecules also provides new opportunities for studying mechanical properties of biomolecules and the interactions in their native environment. AFM has revealed many mechanisms of gene regulation, and will play a more and more important role in life science research.
