RESULTS & CONCLUSION: The new edition of "Essential Drugs List" is to ease the contradiction of coexistence in long-term, but they are difficult to reconcile in short-term.

OBJECTIVE:To promote the adjustment of National Essential Drug List and implementation of Essential Drug List. METHODS:National Essential Drug List was compared with Essential Drug List issued by WHO. Retrieved from statistical results conducted by State Food and Drug Administration, the problem that there were large number of drug in China while little category were included in National Essential Drug List was analyzed, according to practice in China. RESULTS & CONCLUSION: Drug enterprises increased the dosage form and category of preparation blindly because of huge raw drug market, various dosage forms and weak administration to drug enterprises. The characteristics of drug were cheap, high quality, acceptance by state, which decided that the category of drug in Essential Drug List should not be too much. It is necessary to adjust Essential Drug List as the change of situation so as to meet the requirement of public health.

Objective:To investigate the female vaginal Lactobacillus crispatus biofilm by using confocal laser scanning microscopy (CLSM),thus revealing the formation of biofilm. Methods:The cover slide biofilm culture approach in vitro was employed for induction of the vaginal Lactobacillus crispatus biofilm formation. Following the culture for 2, 4, 8, 12, 16, 20, 24, 48, 72, 96 and 120 hours, the cover slide was removed for subsequent staining with the fluoresce in isothiocyanate-conjugated concanavalin A ( FITC-ConA) and propidium ( PI) . This was followed by determination of the formation and characteris-tics of the vaginal Lactobacillus crispatus biofilm by using CLSM. Results:The CLSM images of biofilm formation at different time points were captured, suggesting that the vaginal Lactobacillus crispatus adhe-sion occurred at h 4, which was in reversible attachment, then more and more Lactobacillus crispatus ag-gregated at h 8 to h 20, which was in irreversible attachment. Lactobacillus crispatus clustered at h 20, with early development of biofilm architecture. Then the biofilm with extracellular matrix around the bacte-ria was set up at h 24,with gradual matureation at h 24 to h 48. The biofilm dispersed at h 72. The bio-film density of cultivating for 20 hours was 42 . 7 × 10 -3 ± 6 . 8 × 10 -3 , and for 24 hours increased to 102. 5 × 10 -3 ± 23. 1 × 10 -3 , suggesting a significant difference, P<0. 05. This meant that mature bio-film was formed at h 24 . Conclusion:The vaginal Lactobacillus crispatus is able to form typical biofilm with distinct developmental phases and architecture characteristics. Mature biofilm is formed at h 24 to h 48, then the biofilm begins to disperse.

The continuous cultivation of Rehmannia glutinosa causes the accumulation of phenolic acids in soil. It is supposed to be the reason of the so called "continuously cropping obstacle". In this study, phenolic acids (hydroxybenzoic acid, vanillic acid, eugenol, vanillin and ferulic acid) were degraded by the extracta of all the tested spent mushroom substrate (SMS) and the maximal degradation rate was 75.3%, contributed by extraction of SMS of Pleurotus eryngii. Pot experiment indicated that hydroxybenzoic acid and vanillin in soil were also degraded effectively by SMS of P. eryngii. The employment of SMS enhanced ecophysiology index to near the normal levels, such as crown width, leaves number, leaf length, leaf width and height. At the same time, the fresh and dry weight and total catalpol concentration of tuberous root weight of R. glutinosa was increased to 2.70, 3.66, 2.25 times by employment of SMS, respectively. The increase of bacteria, fungi and actinomycetes numbers in rhizosphere soil were observed after the employment of SMS by microbial counts. The employment of SMS also enhanced the enzyme activity in soils, such as sucrase, cellulase, phosphalase, urease and catelase. These results indicated that the employment of SMS alleviated the continuously cropping obstacle of R. glutinosa in some extent.
