Background and purpose:Quality of life (QOL) questionnaires are tools to assess the quality of life of patients. How to choose a proper questionnaire is the fi rst problem of QOL assessment in clinic research. However, there is few report on it. Our current research compares the data obtained from two world-wide used QOL questionnaire of lung cancer patients EORTC QLQ-LC43 (European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire-Lung Cancer43) and FACT-L (Functional Assessment of Cancer Treatment-Lung) by various statistic methods in order to show differences between the two questionnaires and to provide some suggestions for choosing questionnaires to assess patients’ QOL in clinic research. Methods:The clinic data were obtained from 125 lung cancer patients by two different international QOL questionnaires of lung cancer patients EORTC QLQ-LC43 and FACT-L, and analyzed by various statistic methods such as Pearson correlation analysis, canonical correlation analysis and multiple regression. In addition, we also compare the general modality such as the frame, item numbers and the contents of the subscales, etc. Results:Of the two QOL there are some parts similar in length, ranking type and time construction, even in items. They all contain items in measuring the physical domain, emotion domain, function domain, society domain and lung domain. Correlations between corresponding subscales of the FACT-L and the EORTC QLQ-LC43 are all signifi cant ranging from r=0.331 for the social domain to r=0.664 for the emotional domain. Canonical correlation analysis for the two sets of subscales revealed there are four signifi cant canonical variables (canonical correlation coeffi cient r=0.87 to 0.26 and overall redundancy about 41% ). The eight EORTC QLQ-LC43 subscales are well represented by the fi ve FACT-L subscales (multiple linear regression, R 2=0.531 to 0.766) and the fi ve FACT-L subscales (except relationship with doctors) are also well represented by EORTC QLQ- LC43 subscales (R 2=0.537 to 0.823). The proportion of the corresponding subscale in the total explanation is 50% to 90%. Conclusion:These two questionnaires cover some common parts, but they measure different contents of QOL. Though have the same name, some domains cann’t be compared directly. The two questionnaires cann’t be alternative and the results of them shouldn’t be compaired directly. Both questionnaires are suited for clinic study (e.g compare the effect of two different theropies). But each has its own characters and should be chosen according to reseach goals.

High-density channels are often used to acquire electroencephalogram (EEG) spatial information in different cortical regions of the brain in brain-computer interface (BCI) systems. However, applying excessive channels is inconvenient for signal acquisition, and it may bring artifacts. To avoid these defects, the common spatial pattern (CSP) algorithm was used for channel selection and a selection criteria based on norm-2 is proposed in this paper. The channels with the highest M scores were selected for the purpose of using fewer channels to acquire similar rate with high density channels. The Dataset III a from BCI competition 2005 were used for comparing the classification accuracies of three motor imagery between whole channels and the selected channels with the present proposed method. The experimental results showed that the classification accuracies of three subjects using the 20 channels selected with the present method were all higher than the classification accuracies using all 60 channels, which convinced that our method could be more effective and useful.

In this study, it is to compare the effectiveness of prevention against and treatment of doxorubicin (DOX) induced cardiotoxicity by dexrazoxane and schisandrin B (Sch B) in rats. Sprague-Dawley (SD) rats were randomly divided into the following 6 groups: normal saline group, DOX group, DOX+DEX group, DOX+Sch B (80 mg x kg(-1)) group, DOX+Sch B (40 mg x kg(-1)) group and DOX+Sch B (20 mg x kg(-1)) group. The results showed that Sch B could combat the increase of myocardial enzymes in peripheral blood, decrease of the enzyme activity of myocardial tissue antioxidant enzymes and disorders of systolic and diastolic function of heart in rats intravenously injected with doxorubicin (15 mg x kg(-1)). Sch B was better than DEX in protecting rat against DOX-induced the symptoms. Sch B could protect rat against DOX-induced acute cardiomyopathy and has clinical potential applications.

Early hemoperfusion in poisoned patients can remove poisons rapidly and effectively, which plays an important role in improving the prognosis of patients. The key of hemoperfusion therapy is the safe and effective anticoagulation. The local citrate anticoagulation effect acid is good, it also has little effect on the systemic coagulation mechanism and internal environment of patients, so it is worthy of promotion. We retrospectively analyzed the clinical data and treatment of 273 patients who were poisoned by citrate anticoagulant in the emergency intensive care unit of the Second Affiliated Hospital of Shandong First Medical University, aiming at perfusion of citrate anticoagulant in patients with poisoning. Provide a certain clinical reference.

Objective:To identify the classification characteristics and quality of life (QOL) of breast cancer (BC) patients during chemotherapy, so as to provide basis for improving the sleep and QOL of this group.Methods:A cross-sectional investigation was completed among 421 BC patients in 5 tertiary hospitals in Shanghai, Wuhan, Tangshan and Nanning in 1-12 months of 2016 using validated instruments including self-made general information questionnaire, Pittsburgh Sleep Quality Index (PSQI) and Functional Assessment of Cancer Therapy-Breast (FACT-B).Results:Four latent class of patients were identified through latent profile analysis (LPA), named by badly worse sleep quality(SQ) (C1, n=23), medium-SQ with difficulty to fall asleep (C2, n=127), medium-SQ with worse sleeping process (C3, n=30), none sleep disorders (C4, n=241). Total points of SQ among C1-C4 had significant difference ( χ2 value was 309.28, P<0.05). Age, BMI, job status, whether had surgery and course of chemotherapy between classes had statistically significant differences ( χ2 values were 9.57-25.28, all P<0.05). It had significant difference between C2 and C3, C2 and C4, C3 and C1, C3 and C4 on QOL ( χ2 values were 5.96-52.73, all P<0.05). Conclusion:SQ of BC patients during chemotherapy has heterogeneity among population. Different features of SQ of BC patients have different performance on QOL. Health professionals should keep an eye on patients with features of older age, high BMI, in job status, already received surgery and during early-stage chemotherapy, provide personal nursing intervention to improve SQ and QOL.

OBJECTIVE To provide reference for strengthening the quality of pharmaceutical care in retail chain pharmacies and the professional capabilities of licensed pharmacists， and to meet the public’s pharmaceutical care needs. METHODS A combination of questionnaire survey and informant interview was used to investigate the general information of licensed pharmacists in retail chain pharmacies in Guangdong province， the implementation of pharmaceutical care， the competence and knowledge status of the surveyed licensed pharmacists， and the factors affecting the development of pharmaceutical care. RESULTS & CONCLUSIONS A total of 444 questionnaires were sent out and 326 effective questionnaires were collected， with an effective recovery rate of 73.42%. Among 326 surveyed licensed pharmacists， a college degree or higher accounted for 40.18%， and the pharmacy major or related accounted for 79.75%. A total of 185 （56.75%） of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked had established specified areas of pharmaceutical care； 320 （98.16%）， 137 （42.02%） and 181 （55.52%） of the surveyed licensed pharmacists indicated that the retail chain pharmacies where they worked could provide services such as rational medication guidance for patients， decocting traditional Chinese medicines and establishing health records， etc. The self-assessment scores of the surveyed licensed pharmacists were significantly higher than 3 （median） for competence and knowledge level， but the self-assessment scores for medication therapy management competence and pharmaceutical care practice were relatively low. The surveyed licensed pharmacists believed that the main factors affecting the development of pharmaceutical care in retail chain pharmacies included patients’ lack of trust or cooperation （196， 60.12%）， sales performance requirements （170， 52.15%）， and heavy daily workload （165， 50.61%）. It is recommended that relevant authorities expedite the legislative process of the Pharmacist Law， optimize the continuing education system for licensed pharmacists， and implement a star-rating evaluation system for pharmaceutical care capabilities in pharmacies， so as to encourage retail chain pharmacies and licensed pharmacists to pursue a more specialized development path. At the same time， pharmaceutical retail chain enterprises should shift their business mindset， increase investment in pharmaceutical care， enhance the professional atmosphere in the pharmacies， optimize the compensation structure for licensed pharmacists， and elevate the pharmaceutical care capabilities of both the pharmacies and licensed pharmacists to fulfill the pharmaceutical care needs of the public.
