In medical physiology experiment courses, the students observe the functions and learn the rules of biological body, in order to improve their abilities of scientific observation, practice and reflection. Emotion control means willpower to manage emotion, which is the regular psychological response when we deal with issues. Integrating the emotion control education to professional education is imperative to elevate the general quality of medical students.

38 cases of Benign Monoclonal Gammopathy (BMG) representing 17.9% were screened from 212 cases of M-proteinemia by laboratory examinations. Among the 38 cases, 17 cases had increase of IgG, another 17 cases of IgA and 4 cases of IgM. Their average M-proteins were 1.42, 0.88 and 1.84 g/dl respectively.The salient points of differential of benign or malignant M-proteinemia were also discussed. The recommended sequential laboratory diagnostic procedure of BMG were as follows: tatol serum protein determination, plasma protein zone electrophresis, urine protein analysis, immunoglobulin quantitation and immunoelectrophresis or selective electrophresis.

Objective To observe effects of problem-based learning(PBL) combined with case-based study (CBS)teaching mode in clinical teaching in intensive care unit(ICU). Methods Students from ICU of Fangcun Branch of Guangdong Provincial Hospital of Traditional Chinese Medicine from March 2011 to February 2012 were divided into treatment group (31 cases, with PBL combined with CBS teaching mode) and control group (34 cases, with the traditional teaching mode). Scores of two groups were compared and analyzed and questionnaire survey was conducted in treatment group. Data were processed by SPSS 13.0 statistical software. Measurement data were compared by t-test and data of heterogeneous variance were compared by rank-sum test. Results Treatment group achieved better scores ((85.26 ±5.96) in theory examination and (80.59 ±7.33) in case-analyzing examination) compared with those of control group ((79.17 ±7.31) in theory examination and (76.02 ±9.27) in case-analyzing examination)(P<0.05). PBL combined with CBS teaching mode can stimulate learning interests but it was lack of systematization; most students did not volunteer to speak. Conclusion PBL combined with CBS teaching mode has certain advantages in ICU clinical teaching.

Objective To explore the feasibility using aluminum tripolyphosphate as the synthesis of aspirin model instead of sulfuric acid catalyst. Methods The thermodynamic functions of the reaction system of salicylic acid and acetic anhydride were calculated according to the Benson group contribution method and Joback group contribution method.The enthalpy change,entropy and Gibbs free energy along with the change of temperature as well as the influence of the molar rate of reactants on the equilibrium conversation rate were also studied.Results In the temperature range of 298.15 K to 358.15 K,the reaction enthalpy was less than zero,and was exothermic reaction,and increase of temperature was not conducive to the reaction.The improvement of mole ratio of salicylic acid and acetic anhydride was helpful to improve the equilibrium conversation rate.The theoretical conversion rate could reach 99.58% when the mole ratio of salicylic acid and acetic anhydride was 3.Conclusion From the viewpoint of thermodynamics, the reaction is practical and feasible.
