Objective:To compare psychosocial factors and immune function between patients with breast cancer and benign tumor before operation.Methods:The patients of breast tumor(56 case)were measured by clinical psychological rating scale(EPQ、HAMD、HAMA、LES、SSRS、DSQ)before operation,and their serum levels of IgA, CD_4~+,CD_(19)~+ and the activity of NK cell were measured.The patients of breast tumor were divided into breast cancer group(36 case)and benign tumor group(22 case)bases on results of pathology.Results:In breast cancer group, there were significantly higher scores of neurotic,total and negative life events,immature defense styles,HAMA and HAMD than those in benign tumor group;while NK cell activity,levels of CD_4~+ and CD_(19)~+ and the score of mature defense,social supports,subjective supports and utility degree of supports were marked lower.There were significantly correlation between immune function(NK cell activity,content of CD_4~+,CD_(19)~+,IgA)and psychosocial factors(social support,P score of EPQ,HAMD and HAMA total score,quantity of negative life events etc). Conclusion:Cancer patients had more server psychosocial problems and lower immune function.The immune function of patient with breast cancer before operation is associated with the various psychosocial factors.

Membrane proteins are the main undertakers of biofilm function, and also the most important target group for innovative drug discovery and research. About 60% of drugs targets are membrane proteins. Due to the obvious aggregation and denaturation tendency of membrane proteins in aqueous solution, it is difficult to simulate the membrane like environment to maintain the correct conformation of membrane proteins in vitro, which results in the slower-growing research on the structure and function of membrane proteins and related ligand drugs than that of water-soluble proteins. Membrane protein stabilization technology is the premise of establishing high specificity, high sensitivity and high throughput drug screening methods for membrane protein ligands, which is of great significance. In this paper, some techniques for stable separation and purification of membrane proteins are reviewed, including detergents, artificial membranes, polymers, lentiviral particles and so on, as well as their specific applications in drug screening.

"Tinglizi", the ripe seed of Descurainia sophia and Lepidium apetalum, is a member of Brassicaceae (Cruciferae). Traditionally, the former is called "Nantinglizi" (Descurainiae Semen) while the latter is called "Beitinglizi" (Lepidii Semen). In the theory of traditional Chinese medicine, it has the power to purge lung-fire, relieve dyspnea, promote diuresis and reduce edema, and it is mainly indicated in a case with phlegm-fluid accumulation, cough with excessive sputum, dyspnea with being unable to lie, and general swelling. In view of its wide-spread application in clinic, a comprehensive review of Lepidii Semen and Descurainiae Semen was conducted from the following aspects: herbalogical study, variety identification, historical evolution of processing, chemical constituents, pharmacological effects, quantitative determination and toxicity which could provide reference for further research and development of "Tinglizi".

OBJECTIVETo discriminate Descurainiae Semen and Pantagirus Semen.

METHODA high-performance liquid chromatographic method was developed to establish the fingerprint of Descurainiae Semen, and hierarchical cluster analysis (HCA) and partial least squares discriminant analysis (PLS-DA) were applied to study HPLC fingerprinting and chemical recognition.

RESULTThere exists large difference of chromatographic peaks and its relative peak area of HPLC fingerprints between Descurainiae Semen and Pantagirus Semen, and after conducting statistical analysis, the result demonstrated that all samples were classified into three categories: Descurainiae Semen, Pantagirus Semen and their mixtures.

CONCLUSIONThe developed HPLC fingerprint combined with chemometrics can be utilized to discriminate between Descurainiae Semen and Pantagirus Semen, which was quick, simple, accurate and reliable an can provide the basis for the characterization and quality assess of Descurainiae Semen and Pantagirus Semen.

OBJECTIVETo investigate the factors affecting the survival and to predict the survival time of glioma.

METHODSGraph method was applied to fit the type of probability distribution of patients' postoperative survival time. As one suitable model, Weibull regression model tested by residual analysis was used to identify prognostic factors for postoperative survival and to predict patients' post-operative survival time.

RESULTSIn multivariate analysis of Weibull regression model, following characteristics showed significant influence on postoperative survival time including: sex, age, epilepsy, type of glioma, density of glioma, type of surgery, times of surgery and mode of postoperative therapy. According to predictive value, patients were clustered into three groups. The survival probability of one year for the first group was less than 50% and that of five years for the second group about 50%, for the third group around 80%.

CONCLUSIONSex, age, epilepsy, type of glioma, density of glioma, type of surgery, times of surgery and mode of postoperative therapy were important risk factors and Weibull regression model might help to predict patients' postoperative survival time.

Objective To provide a basis for humanity education in the university by a survey of clinical graduates' recognition of humanity education and humanity curriculum. Method An anony-mous questionnaire was adopted and 514 questionnaires were distributed to the 2014 clinical gradu-ates in Peking University Health Science Center about their understanding of humanity education and humanity curriculum. The investigation data was double entried in Epidata 3.1, apply SPSS 19.0 to make the descriptive analysis, chi-square test. Results 69.3% (167/241) students believed humanity education enhanced their professionalism and competency;52.7%(127/241) students believed humanity education enhanced their doctor-patient communication; 36.4% (174/478) students believed their hu-manity knowledge came from their instructors' personal example and teaching;31.1%(149/479) students said the best way of humanity education was through social practice;59.7%(286/479) students consid-ered the combination of classroom lecturing and discussion as the best way to humanity education. As to the major weaknesses in humanities education, 46.9%(113/241) students chose insufficient curriculum, 23.2%(56/241) chose lack of practical value and 23.7%(57/241) chose monotonous teaching methods;Conclusion The best approach to humanities teaching is to combine class lecture with class discus-sion. Besides, hidden curriculum also contributes to humanity education. The enhancement of clinical graduates education relies heavily on humanity education and its emphasis should be laid on the training of humanity teachers, the study of humanity curriculum and learning from other universities.
