Biobank is a biorepository which organized for collecting and storing human biospecimen as well as associated information for research uses.Biobank is the fundamental platform which translates the basic research result into clinical practice.It also plays an important role in disease diagnosis,new drug development,disease-related genetic research and epidemiological studies.The rise of translational medicine promotes the construction and development of the biobank.This review highlights the necessity to establish biobank,and focuses on the recent advances of the modem type of biobank,quality control of biospecimens,construction of biobank,best practices and guideline applied for biobank.This review also provides information for improvement of biobank.

0.05).It was revealed that all the patients followed up 3 to 6 months after treatment were free from complaints of the involved teeth,with nomal food intake and mastication.No abnormal adjacent tissues of dental roots were detected by imaging examination.Conclusion For the vital teeth,the similar clinical effect may be obtained by one-visit RCT and multi-visit RCT.

OBJECTIVETo establish an HPLC method for the content determination of baicalin, wogonin, chlorogenic acid, caffeic acid, cichoric acid, corynoline and adenosine in Pudilan Xiaoyan oral liquid.

METHODThe analysis was performed on a Phenomenex Luna C18 column (4.6 mm x 250 mm, 5 µm) with a gradient mobile phase of methanol-0.1% trifluoroacetic acid solution system at flow rate of 1.0 mL · min(-1). The detective wavelength was at 280 nm. The column temperature was 30 °C.

RESULTThe standard curves of seven studied components show good linearity in their concentration ranges with r ≥ 0.999 6. The average recovery was 98.73%-102.1% with RSD less than 2.6%.

CONCLUSIONThe method is rapid, simple and accurate, and can be applied for the quality control of Pudilan Xiaoyan oral liquid.

Ebola virus (EBOV) and Marburg virus (MARV) belong to the family Filoviridae. Filoviruses cause severe filovirus hemorrhagic fever (FHF) in humans, with high case fatality rates, and represent potential agents for bioterrorism and biological weapons. It is necessary to keep surveillance of filoviruses, even though there is no report of their isolation and patients in China so far. To characterize MARV morphology, the Lake Victoria marburgvirus--Leiden was stained negatively and observed under a transmission electron microscope which is one of important detection methods for filoviruses in emergencies and bioterrorism. MARV showed pleomorphism, with filamentous, rod-shaped, cobra-like, spherical, and branch-shaped particles of uniform diameter but different lengths. Pleomorphism of negatively stained MARV is summarized in this article, so as to provide useful information for possible electron microscopic identification of filoviruses in China.

Strong inhibition of Bacillus subtilis strain NJ-18 on mycelia growth of Alternaria solani was observed in the antagonistic tests by cylinder plate methods, and the inhibition width was 21.5 mm. Observation under microscope found that the supernatant of fermentation from NJ-18 could make the pathogen hyphae cells malformed and swelled, and consequently the growth of the pathogen was inhibited. Determining of the colonization in potato plants by the signed rifampicin-resistance in NJ-18 showed that it could colonize well in the plants, the colonization quantity of NJ-18 in the root and stem of the potato detected 30 days after fermentation irrigation was 103 CFU/g plant’s fresh weight. In pot experiment, we inoculated the tomato plants with the spore suspensions of Alternaria solani after spraying the fermentation of NJ-18, the results were investigated in 14 days and the efficacy in controlling the disease was 72.9%, which was significantly higher than 45.7%, the efficacy resulted from spray treatment of 2000 fold dilution of 50% iprodione wetable powder.

Objective:To investigate whether transplantation of mesenchymal stem cells(MSCs)through renal arteries can protect kidney from acute tubular necrosis(ATN),so as to lay a foundation for MSC transplantation in treatment of ATN.Methods:Five-week-old nude mice were randomly divided into three groups:normal control group(n=10),acute tubular necrosis(ATN)model group without(n=10)and with MSCs treatment group(n=11).ATN nude mice were induced with 50% glycerin.MSCs labeled with enhanced green fluorescent proteins(EGFP)were injected into kidney through renal arteries.Serum creatinine was determined in all groups and pathological changes of renal tissues were detected using H-E staining.The amount and distribution of the EGFP-marked MSCs in renal tissues were determined with fluorescence microscope.Results:Degeneration and exfoliation of renal tubular epithelial cells,and even renal tubular tamponade with cast-off cells were observed in the ATN group;these pathological changes were mainly located at renal cortex and juncture of renal cortex and medulla.The damages were greatly alleviated in the ATN+MSCs transplantation group,with no swelling of epithelial cells,nuclear condensation or edema.Fourteen days after MSCs transplantation,EGFP positive cells were increased in renal tubules of recipient mice.Conclusion:The MSCs transplantation via renal artery can locate in renal tubular epithelium,and promote the repair of injured renal tubular epithelial cells.
