Molecular technologies are sensitive, fast, and cheap in the study on microbial ecology. However, these methods do not provide information about morphology, number, and spatial distribution of the microorganisms. In contrast, Fluorescence in situ hybridization (FISH) combines the precision of molecular biology with the visual information from microscope, and permits visualization and identification of individual miciobial cells within their natural habitat. FISH not only allows the detection of slow growing microorganisms, but also of yet-to-be cultured. It is useful for many applications in diagnosis and assessment of the population structure of complex microbial communities, and is a powerful tool for molecular ecology studies in microbiology, In this paper, major techniques and progresses of FTSH were described. Its application in microbial ecology, as well as problems , pitfalls, and perspectives of FISH are discussed.

To study the effects of alkaloids from Coptidis Rhizoma on low-density lipoprotein receptor (LDLR) mRNA expression and antihyperlipedemic levels. The LDLR mRNA expression were detected by real time fluorescence quantitative PCR, and the levels of total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-c) and high-density lipoprotein cholesterol (HDL-c) in serum were measured at the first and last examination. The results show that, after the drug treatment, compared with the model group, each drug group showed a lipid-lowering effect. Especially, coptisine, palmatine, jatrorrhinze were significantly reduced TC, TG, LDL-c (P < 0.05, P < 0.01), and increased HDL-c (P < 0.01). In addition, they also increased mRNA expression of the LDLR in liver and HepG2 cells. The results showed that alkaloids from Coptidis Rhizoma can regulate lipid metabolism disorder, and coptisine have the best lipid-lowering effect.

OBJECTIVETo investigate the preparation of Shuanghuanglian taste-masking microspheres by spray-drying.
METHODTraced the compounds bitterness source, marked its curve and optimized the microspheres preparation by taking taste evaluation, microspheres yield and inclusion rate as the indexes.
RESULTThe bitter taste of compounds comes from Forsythia suspensa. The best taste-masking material is Eudragit E100. The optimal spray-drying parameters: solvent concentration 2.0%, inlet air temperature 75 degrees C, aspirator 35.0 m3 x h(-1), spray flow 0.35 m3 x h(-1), pump speed 8.0 mL x min(-1).
CONCLUSIONThe spray-drying as a method of masking the traditional Chinese medicine compound taste have advantages of simple process and efficient masking.

OBJECTIVEBitterness appraisal method of Chinese drugs and preparation is established.
METHODThe investigation table was designed by analogical epidemiology investigation. Then the statistical analysis was made for the data, and berberine bitter taste threshold was calculated. Verification experiment was made by two kinds of complex prescription.
RESULTBerberine is determined as the standard bitter material. Statistics results about verification experiment are significant.
CONCLUSIONThe system could be bitterness appraisal method of Chinese drugs and preparation.

We investigated the situation of leptosperosis infection among patients with fever in Hainan Province in China.Blood samples of patient from Hainan Province in the year of 2015 were detected for Leptospira by microscope agglutination test (MAT),enzyme-linked immunity test (ELISA) and polymerase chain reaction (PCR),respectively.Results showed that 179 blood samples of patients with fever were found,and microscope agglutination test detected 40 positive samples,with a infection rate of 22.35%.The infection rate was 21.65%(21/97) for male and 23.17%(19/82) for female.Seven groups of bac teria were found including Leptospira serogroup icterohemorrhagie,ballom group,autumralis group,pomona group,grippotyphosa group,Sejroe group and Batavia group.Thirty-eight samples were tested positive by ELISA,with a positive rate of 21.23 %,in which six samples were IgM positive (detection rate =3.35 %) and 32 samples were IgG positive (detection rate=17.88 %).Serological detected with MAT and ELISA methods results were consistent and that were tested negative by PCR.Results of our study supported the presence of Leptospira infection infection among the patients with fever of unknown origin (FUO) in Hainan Province.The main types are Leptospira serogroup icterohemorrhagie.
