ABSTRACT
Objective:To present briefly introductions and evaluations on the constructs, psychometric properties (reliability, validity, reactivity etc.) and applications of the system of Quality of Life Instruments for Cancer Patients QLICP(V1.0) including 12 kinds of scales for patients with head and neck cancer, brain cancer, lung cancer, breast cancer, esophageal cancer, gastric cancer, colorectal cancer, liver cancer, cervical cancer, ovarian cancer, leukemia and lymphoma.Methods:Based on our measuring data from relevant patients at hospitals, the constructs, characteristics and psychometrics of the system above were analyzed and presented. Internal consistency reliability for each domain and the overall scale was assessed using Cronbach's alpha coefficient, and test-retest reliability through calculating the Pearson correlation coefficient between the first and second assessments. The criterion-related validity was evaluated by correlating corresponding domains of two instruments. Responsiveness was assessed through comparing the mean difference between the pre-treatment and post-treatments with standardized response mean (SRM). The use agreements and literature reviews of this system were used to understand the applications of 12 kinds measurement scales.Results:The quality of life scales for 12 kinds of cancer patients of the system QLICP(V1.0) have good construct( 5 domains, 11-15 facets), reliability, validity and a certain degree of responsiveness. The internal consistency reliability Cronbach's α coefficients for the overall scale of QLICP in different cancers was from 0.67 to 0.92, and the test-retest reliability (correlation coefficient) was from 0.61 to 0.99. The criterion-related validity (correlation coefficient) was for the overall scale of QLICP in different cancers was from 0.28 to 0.89, and the responsiveness SRM was from 0.25 to 1.28. And also they were widely used in clinical practice and relevant studies for the corresponding cancers.Conclusion:The system QLICP(V1.0) is of outstanding characteristics with all psychometrics meeting requirements and better construct (clear hierarchical structure with items→ facets→ domains→ overall ), and can be used widely in clinical practice further.
ABSTRACT
Objective@#To compare the differences and similarities among the system of quality of life instruments for cancer patients (QLICP) V1.0, the quality of life questionnaire (QLQ) from European Organization for Research and Treatment of Cancer (EORTC) and Functional Assessment of Cancer Therapy (FACT) from Center on Outcomes, Research and Education (CORE) of America.@*Methods@#Based on literatures and our measuring data from patients at hospitals, the constructs, characteristics and psychometrics of the systems above were analyzed and compared. Internal consistency reliability was assessed using Cronbach α coefficient for each domain, and test-retest reliability through calculating the Pearson correlation coefficient r between the first and second assessments as well as intra-class correlation (ICC). Construct validity was evaluated by Pearson correlation coefficient r (item-domains correlations) and factor analysis. The criterion-related validity was evaluated by correlating corresponding domains of two instruments. Responsiveness was assessed through comparing the mean difference between the pre-treatment and post-treatment with standardized response mean (SRM).@*Results@#The instruments of three systems were of different outstanding characteristics with all psychometrics meeting requirements. Measurements for 12 types of cancers showed that the internal consistency reliability Cronbach α coefficient for the overall scale of QLICP (V1.0) was 0.67-0.92, and for FACT was 0.79-0.98. The test-retest reliability (r or ICC) for the overall scale of QLICP (V1.0) was 0.61-0.99, and for FACT was 0.60-0.98. The SRM for the overall scale of QLICP (V1.0) was 0.25-1.28, and for FACT was 0.11-0.83. However, the QLICP was of better construct (clear hierarchical structure with items→facets→domains→overall) and Chinese culture.@*Conclusion@#The instruments of three systems can be used as the instruments to assess quality of life for patients with cancer with selections basing on different settings.

ABSTRACT
Objective To explore the effects of physiological deep-sea water(PDSW) on hyperthermal tolerance of Kunming (KM ) mice in the 45 .0 ℃ environment .Methods Deep-sea water from the south Chinese sea was processed ,and the metallic ele-ments dissolved in the DSW were analysed .The mice were randomly divided into 2 groups :the control group received tap water ;the experimental group treated with PDSW for 15 d .And then the mice were fed in the 45 .0 ℃ conditions .The survival time and histo-morphometric analyses of the brain ,lung ,heart ,liver and kidney were investigated .Results The survival time in PDSW-fed group was significantly longer than that of the control group (P< 0 .05) .Moreover ,histomorphometric analyses showed that PDSW could protect the brain ,lung ,heart ,liver and kidney of KM mice from the 45 .0 ℃ conditions .The results of western blot revealed that ex-pression of HSP72 of liver tissues for PDSW-fed group substantially increased ,when compared with the control mice(P< 0 .05) . Conclusion PDSW could improve hyperthermal tolerance of KM mice ,which maybe in the relation with expression of HSP72 pro-moted by PDSW .
ABSTRACT
Chemotherapy and molecular targeted therapy are the main treatments in unresectable gastric cancer. In recent years,due to the adjustment and optimization of chemotherapy regimens which are consist of fluorouracil,platinum and taxane,the survival time of gastric cancer patient has been prolonged and the quality of life has been improved. The molecular targeted therapy in gastric cancer arouses more and more concern,and there are many phrase Ⅲ clinical trials which are used to assess the efficacy of molecular targeted therapy. The advances of chemotherapy and molecular targeted therapy bring new hope to advanced gastric cancer patients.
ABSTRACT
Objective To research the value of using constant circling individual training program to improve surgery clinical skills of clinical medical specialty interns.Method 42 interns were divided into 3 groups:A(excellent),B(medium) and C(poor) according to their scores in entrance clinical skill test and each group would perform respective training program including conventional training,unified intensive training and intensive training in person.Their performance would be scored six times during the whole process of training.Results Compared with the final scores with beginning scores,the number of students scored A increased significantly meanwhile the number of students scored C decreased obviously.Conclusion The constant circling individual training program combined with effective unified test can benefit improving the surgery clinical skills of the interns of clinical medicine.
ABSTRACT
Objective To study the clinicopathological features and treatment modality of patients with gastric remnant cancer after distal gastrectomy. Methods The data of 25 patients with gastric remnant cancer undergoing surgery during the recent 9 years were analyzed retrospectively.Results Patients with gastric remnant cancer showed a greater male predominance(5∶1). The mean interval between previous gastrectomy and diagnosis of gastric remnant cancer was 24.5 years,ranging from 12 to 35 years.The primary operation was Billroth Ⅱ reconstruction in 80% of the cases. R0 resection for gastric remnant cancer was performed in 14 cases,Palliative resection in 11 cases,and adjuvant chemotherapy in 18 cases. The 1-,3-and 5-year overall survival rate was 72.0%,56.0% and 36.0%,respectively,while the respective survival rate was 78.5%,71.4%,and 50.0% in radical surgery group,and 63.6%,36.3% and 18.1% in palliative surgery group(P
