Objective:To explore the contents and methods of clinical comprehensive evaluation of microecologics, with the example of Bifidobacterium quadruple viable tablet, in order to provide evidence for clinical rational use of microecologics, and microecologics research, development and related decision-making, and to promote rational use of medications. Methods:Based on the research data collected from systematic literature search, health technology assessment methods such as evidence-based medicine and pharmacoeconomics evaluation were used to estimate the safety, efficacy, economics, suitability, accessibility and innovation of Bifidobacterium quadruple viable tablet. Results:In terms of efficacy, Bifidobacterium quadruple viable tablet showed significant therapeutic effects in the treatment of pediatric diarrhea, antibiotic-related diarrhea, diarrhea-predominant irritable bowel syndrome, and secondary diarrhea caused by diseases such as ulcerative colitis, as well as constipation and functional dyspepsia. It can also be used in the treatment of various diseases such as Helicobacter pylori related gastritis, liver cirrhosis, non-alcoholic fatty liver disease. In terms of safety, the incidence of adverse effects of this medication was low, and most were mild to moderate and transient symptoms. In terms of economics, compared with mesalazine alone in the treatment of ulcerative colitis, the incremental cost-effectiveness ratio of combination of Bifidobacterium quadruple viable tablet and mesalazine was 1 743.2. Besides, the daily treatment cost of Bifidobacterium quadruple viable tablet was lower than that of combination of Bifidobacterium triple viable and Bacillus licheniformis (1.87 to 2.80 yuan vs. 2.08 to 5.78 yuan). In terms of innovation, this medication had multiple patents and had been identified as a high-tech product in Zhejiang Province. In terms of suitability, the overall suitability of use and technical characteristics of medication were good. It could be further improved in the aspects of dosage form and system. In terms of accessibility, the price of the medication was stable, affordable and accessible to the general public. Conclusions:Based on the existing evidence, Bifidobacterium quadruple viable tablet presented effective with supported evidences, good safety, accessibility and innovation. The suitability can be further optimized. However, more in-depth and targeted research is needed in terms of economics and innovation in different clinical applications, and there is space for optimization in medication suitability.

OBJECTIVE:To estab lish the fingerprint ,analyze the monosaccharide composition and content ,investigate the inhibitory effects of the polysaccharide from Desmodium styracifolium on α-glucosidase in vitro . METHODS :Polysaccharide from D. styracifolium was prepared by water extraction and ethanol precipitation. After hydrolyzed by TFA and derived by PMP ,HPLC method was adopted to establish the fingerprint (using glucose peak as reference ),and analyze the constituent and content of monosaccharide. The content determination was performed on Phenomenex Luna C 18 column with mobile phase consisted of acetonitrile-0.05 mol/L potassium phosphate (pH adjusted to 6.8 with sodium hydroxide )in gradient elution at the flow rate of 0.8 mL/min. The detection wavelength was set at 250 nm,and column temperature was set at 30 ℃. The sample size was 10 μL. Using acarbose as control ,PNPG assay was used to investigate the α-glucosidase inhibitory activity of polysaccharide from D. styracifolium. RESULTS :There were 9 common peaks in HPLC fingerprints of 18 batches of samples ,and the similarity of 15 batches of samples was higher than 0.90. Totally 7 peaks were identified as mannose ,rhamnose,galacturonic acid ,glucose, galactose,xylose and arabinose. The contents of rhamnose ,galacturonic acid ,glucose,galactose and arabinose were 0.471-2.092, 1.379-8.919,2.560-35.679,1.194-6.905,0.566-4.158 mg/g,respectively. Based on rhamnose ,the molar ratios of the other four monosaccharides were 1.58-4.07,2.26-19.95,2.20-4.21 and 1.31-2.86,respectively. The inhibitory activity of polysaccharide from D. styracifolium on α-glucosidase increased with the increase of dose ,and the half inhibitory concentrations of it was 0.70 mg/mL, lower than 7.76 mg/mL of acarbose (positive control ). CONCLUSIONS :Glucose is the main component of D. styracifolium polysaccharide in different batches ,and the contents of monosaccharides are different. The polysaccharide from D. styracifolium have significant inhibitory activity on α-glucosidase,which is better than that of acarbose.
