With the deepening of the study on traditional Chinese medicinal quality and the rising requirements of TCM quality control, the demand of setting TCM quality were emphasized,as well as higher education course. Surrounding the purpose of exploring the related issues of the traditional Chinesemedicinal courses setting and promoting the college curriculum innovation capability,the paper mainly discussed the course open orientation, the teaching characteristics, objectives, idea, the core content and the training scheme, as well as the plan of course and teaching material construction depended on these contents.

To study the initiatives and progress of African nations in promoting the development of traditional medicine to determine if these measures can be applied to the protection of traditional Chinese medicine knowledge. Information research methods were used to collect and analyze relevant literature. The development of African traditional medicine has been effectively promoted through various measures taken by African organizations and governments. In recent years, Africa has achieved remarkable results in promoting the development of traditional medicine. Many other countries will benefit from studying their examples and adopting similar measures.

Pure and drug hydrophilic matrix tablets were prepared by direct compression method with theophylline as a model drug. The characteristics of four hydrophilic matrix polymers, hydroxypropylmethylcellulose (HPMC), polyethylene oxide (PEO), sodium alginate (NaAlg) and xanthan gum (XG), were compared by investigating the water absorption, swelling, erosion and gel layer strength. The sequence of water absorption rate was XG >> NaAlg (H) > PEO > NaAlg (L) >> HPMC; The sequence of swelling index was XG >> PEO >> HPMC >> NaAlg; The sequence of erosion rate was NaAlg (L) > NaAlg (H) >> PEO80 > PEO200 > PEO300 > XG approximately PEO400 approximately K4M > K15M > PEO600 approximately K100M; The sequence of the gel layer strength was PEO > HPMC > XG >> NaAlg. For the PEO and HPMC matrix tablets, with the polymer molecular weight increased, the drug release mechanism was gradually transferred from mainly depending on the erosion to the diffusion; for SAL matrix tablets, the drug release mainly depends on erosion mechanism; and for XG matrix tablets, the drug release mainly depends on non-Fick diffusion mechanism. Comparison of the performance difference between the polymer materials will contribute to rational design and prediction of drug release behaviors from matrix tables and ultimately to achieve clinical needs.

Good Agricultural Practice for Chinese Crude Drugs is one of the effective measures for protecting and developing resource of Chinese crude drugs..We analyzed the current situation of GAP,discussed its questions and development.

By reviewing the selection principle and evaluation criterion on the periodicals in the well-known evaluation and index system of China and abroad, the article provides both the related information for researchers to get a general idea of this system and the criterion for periodicals to join the system.

OBJECTIVE: To investigate the clinical features and therapeutic effects of sudden deafness after radiotherapy combined with chemotherapy in nasopharyngeal carcinoma patients. METHOD: Clinical data of 42 nasopharyngeal carcinoma patients suffered from sudden deafness after radiotherapy combined with chemotherapy were analyzed retrospectively. Among the 42 patients, 2 showed moderate deafness, 4 presented excessive deafness, 30 suffered from severe deafness, and 6 exhibited profound deafness. The audiogram pattern of 33 patients met with the type of high tone frequencies hearing loss, and that of the rest 9 cases showed hearing loss at all frequencies. All patients received medical therapy combined with hyperbaric oxygen therapy. RESULT: Of all the cases with hearing loss, 2 were cured, 2 showed excellent recovery, 9 came out partial recovery, and 29 showed no response to the treatment. The total effective rate was 30.95%. For the accompanied symptoms, none of the 30 cases of tinnitus were relieved, 3 out of 10 cases of aural fullness were cured, and the 5 cases of dizziness or vertigo were all improved. CONCLUSION The sudden deafness after radiotherapy combined with chemotherapy in patients with nasopharyngeal carcinoma is closely related to radiotherapy. The hearing loss is serious, and the therapeutic effects are not satisfactory.

Objective To investigate the growth and expression of PDGF of VSMCs in response to stimulation of autologous serum and mechanical injury. Methods An vitro model simulating the condition as possible as that after PTA.PDGF of every medium sample from every group was detected by ELISA,and the values of MTT of every cellular sample was measured by MTT to show the growth and proliferation of every group. Results After stimulation by autologous serum and mechanical injury,SMCs of the experimental group showed the value of MTT increasing,but SMCs in control group reached on 3rd day.At the same time,the expression of PDGF also increased gradually,obtaining peak gradually up to peak on day 4/5 nearly 2.0-fold as much as that of SMCs in the control group. Conclusions After on the 5th day,stimulation with autologous serum and mechanical injury,VSMCs of rabbit showed the stronger ability of growth/proliferation,and autocrine of PDGF also increased gradually,reaching peak on 4-5 d,probobly simulating to those in vivo.

Objective To analyze the correlation of metabolic syndrome (MS) and its components with a future development of diabetes mellitus (DM) in elderly patients. Methods In 2007, the cohort study was carried out among the 2001 baseline population. The criteria which was proposed by international diabetes federation in 2005 was referred to diagnose MS. Results MS predicted the future development of DM (RR = 4. 70, 95% CI:3.23～6.85). Among MS components, fasting glucose exhibited the highest association with DM. The univariate analysis showed that while fasting glucose was more than 5. 6 mmol/L, the RR(95% CD was 9. 68(6. 59～ 14.23). And multiple factors analysis showed that while fasting glucose was 5.60 mmol/L～6. 09 mmol/L, the RR(95% CD was 5. 49(3. 38～8. 92). While glucose level was more than 6. 1 but less than 7.0 mmol/L, the RR(95% CI) increased to 14.44(9.29～22.44). However, along with the increasing of cluster number of MS components from 1,2,3,4 to 5, the corresponding RR increased from 2. 92, 5. 67, 12. 28, 19. 52 to 37. 83. Conclusions MS increases the risk of DM. Among MS components, fasting glucose level is the strongest risk indicator of DM.

Objective DryLab software was used to assist high performance liquid chromatography (HPLC) method to test and isolate six Cytochrome P450 (CYP450) probe substrates.Methods Six CYP450 probe substrates were selected and the right HPLC method was developed and validated with the assistance of DryLab software.Results The new HPLC method with the assistance of DryLab software could test and isolate six probe substrates with degrees of isolation more than 2.00. The correlation coefficients (R> 0.999 8) indicated high linear correlation between the concentrations and the peak areas among six probe substrates. Recovery studies showed good results for all the probe substrat from 86.38% to 110.29%. And therelative standard deviation (RSD) ranged from 1.69% to 3.80% with its intra-day and inter-day precision ranging from 0.42% to 2.01%, and 1.36% to 2.29%, respectively.Conclusions The developed HPLC method with the assistance of DryLab could test and isolate six probe substrates with shortertime than the HPLC method alone.
