Under the high pressure of employment, traditional teaching method that is based on inculcating the knowledge to students does not adjust current condition any more. So, we start to looking for a new, more suitable way of teaching.--Project Based-on Learning, and have analyzed the advantages in health information technology teaching by construction doctrine in combination with the concept and principle in wedlock construction. At the same time we introduce project Based-on Learning in concrete application to find a way to put the theory into practice.

Objective To analyze the composition principles of Chinese patent drugs containing Rehmanniae Radix;To provide reference for clinical application and new drug research and development.Methods Based on the software Traditional Chinese Medicine Inheritance Support System (V2.0), the authors built prescription database containing Rehmanniae Radix in National Standard for Chinese Patent Drugs (NSCPD). Then the authors adopted the statistical module by using data mining methods such as association rules and improved mutual information method, with a purpose to analyze the attending disease, combination rules and the core groups in prescriptions containing Rehmanniae Radix.Results In 357 prescriptions containing Rehmanniae Radix, 17 most commonly used drug combinations were mined. Meanwhile, two diseases, namely, insomnia and vertigo were chosen from the 22 diseases that Rehmanniae Radix was most frequently used to make deeper analysis, showing that Rehmanniae Radix can achieve different therapeutic effects through different compatibility.Conclusion Prescriptions containing Rehmanniae Radixin NSCPD mainly concentrate on clear heat and cool blood, and nourish Yin. The composition principles obtained from the research that Rehmanniae Radix used when curing different diseases can fully play the efficacy of RehmanniaeRadix and provide evidence for clinical scientific formulae.

Objective To investigate the protein expression of the canonical transient receptor potential(TRPC)channel in the hippocampus of amyloidβprotein(Aβ)?induced Alzheimer’s disease(AD)mice. Methods A total of 36 ICR mice were randomly divided into AD group and control group,with 18 rats in each group. AD mice models were established by Aβ1?42 microinjection into the lateral intracerebroventricular. Learning and memory abilities of the mice were determined using Morris water maze. All TRPC1?TRPC7 mRNA levels in the hippocampus of the mice were detected using reverse transcriptase polymerase chain reaction(RT?PCR). Hippocampal TRPC4 protein expression was examined using immunofluorescence and Western blotting methods. Results Water maze test results showed that the escape latency of AD group were significant?ly longer than that of the control group(P<0.01),and that the target quadrant occupancy of AD group was significantly shortened(P<0.01)and the frequency of platform crossing of AD group was significantly reduced(P<0.01). RT?PCR results showed that all TRPC(TRPC1?TRPC7) mRNA were expressed in the hippocampal of both AD group and control group. Among these channels ,only TRPC4 mRNA levels of AD group was higher than that of the control group(P<0.01). Immunofluorescence images showed that TRPC4 expressed on the membrane of neurons and the intensities of the immunofluorescence of TRPC4 in AD group were stronger than that of control group. Western blotting results showed that the TRPC4 protein expression of AD group was higher than that of control group(P<0.05). Conclusion The increase of TRPC4 protein expression in the hippocampus of mice after intracerebroventricular injection of Aβ1?42 oligomers suggests that TRPC4 may be involved in the pathogenesis of AD induced by calcium homeostasis.

This study aims at trying to establish a novel method of sterility test for injections based on biothermodynamics, in order to overcome the deficiencies of routine sterility tests such as long detecting cycle, low sensitivity and prone to misjudgments. A biothermodynamics method was adopted to rapidly detect the microorganism contamination of injections by monitoring the heat metabolism during the growth of microbe. The growth rate equal to or greater than zero and the heat power difference of P(i) and P(0) with three folds higher than the noise of baseline were chosen as indexes to study the heat change rule of microbe. In this way, the effectiveness of the new method to detect strains required by conventional sterility test or in injection samples was also investigated. Results showed that the Gram-positive bacteria, Gram-negative bacteria and fungi demanded by sterility testing methodology could be detected by biothermodynamics method within 10 hours, with the sensitivity lower than 100 CFU x mL(-1). Meanwhile, this method was successfully applied to the sterility test of Compound Yinchen injection (FFYC), Shuanghuanglian powder injection (SHL) and Compound Triamcinolone injection (TAND) which were sterilized with different degrees. Therefore, the biothermodynamics method, with advantages of fast detection and high sensitivity, could be a complementary solution for conventional sterility tests.
