Objective To explore the clinical characteristics of neonatal dengue fever. Methods The clinical data from 4 neonates with dengue fever who were admitted and treated in 2014 were retrospectively analyzed and the related literatures had been reviewed. Results Four cases of neonatal dengue fever were all males. Three cases were mother to child transmission, the age at onset was 1 to 7 days after birth, and their mothers suffered with prenatal fever and were diagnozed of dengue fever during perinatal period. One case was community acquired, the age at onset was day 21 after birth and the neonate was bit by mosquito the day before. All four neonates had fever, two cases had rash, and one case had hemorrhagic spot. None of them had jaundice or cough. All of them had thrombocytopenia ( 30-125 )× 109/L, prolonged activated partial thromboplastin time ( 44 . 0-89 . 8 s), and increased aspartate aminotransferase (AST) ( 46-71 U/L). Three cases had declined ifbrinogen ( 1 . 36-2 . 53 g/L). Two cases had increased CK-MB ( 29-86 U/L). Two cases had increased CRP ( 3 . 00-46 . 05 mg/L). After the treatment of anti-infection and intravenous immunoglobulin, all of them were cured and discharged. The duration of hospital stay was 4-17 days. Conclusion The clinical manifestations of neonatal dengue fever were mainly fever and blood coagulation dysfunction, clinical symptoms are mild and lack of speciifcity, and prognosis are good. Mother to child transmission is one of the ways of dengue virus infection.

BackgroundThe quest to look for seed cells is a hot spot of cornea transplant research in solving the problem of the lack of donor. Bone marrow mesenchymal stem cells(BMSCs) have been successfully induced into retinal ganglion cells(RGCs) in vivo,but the successful induction of BMSCs into corneal endothelial cells has not been reported.Objective This experiment was to study the transplantation of BMSCs on corneal endothelial surface using the splitting Descemet's membrane. MethodsFour healthy adult rhesus monkeys were divided into the experimental group ( 3 monkeys) and control group ( 1 monkey). Mesenchymal stem cells (MSCs) were isolated from bone marrow by density gradient centrifugation combined with adhering means. The cultured cells were identified by flow cytometry and its ability to differentiate was determined by allowing them to differentiate into adipocytes in vitro and labeled by 5-bromodeoxyuridine ( BrdU ) for subsequent identification. Corneal grafts of 7 mm in size with tearing of the Descemet' s membrane were prepared in the experimental group and control group. After labeling by 5-bromodeoxyuridine( BrdU ) ,cultured cells were transplanted onto the endothelial surface of cornea grafts in the experimental group, but no cultured cells were seeded in the graft of the control group. The corneal grafts were then sutured in situ, and were removed 1,2 or 3 months after operation to examine the distribution and connection between transplanted cells and their morphologic changes under the electron microscope. Results High purity MSCs were harvested by density gradient centrifugation combined with adhering method. Cultured cells reached confluency after 12 to 16 days, presenting with a spindle shape and parallel or swirling arrangement. Flow cytometry analysis showed that 94.26％ of cells were positive for CD29,7. 51％ for CD34 and 4. 02％ for CD45. Larger nuclei filled with plastosomes, golgiosomes and rough endoplasmic reticula were found on the graft under the transmission electron microscope( TEM ). After 3 weeks, MSCs were differentiated into adipocytes where Oil Red O staining resulted in an orange-red staining in the cytoplasm and blue staining in the nuclei. The transplanted cells attached loosely on the endothelial surface of the corneal graft and came in contact with each other in one month. The shape of the cells appeared as spindle-shaped and polygonal after 2 months and became tightly packed after 3 months. The positive cells retained the BrdU label and presented with brown nuclei. No endothelia cells grew in the cornea graft in the control group, with an absence of BrdU labeling. Conclusions Mesenchymal stem cells can be transplanted onto the corneal endothelial surface successfully and form a monolayer using the centrifugation method, and present with good survival and proliferation ability.

In order to construct an integrated DNA barcoding database for identifying Chinese animal medicine, the authors and their cooperators have completed a lot of researches for identifying Chinese animal medicines using DNA barcoding technology. Sequences from GenBank have been analyzed simultaneously. Three different methods, BLAST, barcoding gap and Tree building, have been used to confirm the reliabilities of barcode records in the database. The integrated DNA barcoding database for identifying Chinese animal medicine has been constructed using three different parts: specimen, sequence and literature information. This database contained about 800 animal medicines and the adulterants and closely related species. Unknown specimens can be identified by pasting their sequence record into the window on the ID page of species identification system for traditional Chinese medicine (www. tcmbarcode. cn). The integrated DNA barcoding database for identifying Chinese animal medicine is significantly important for animal species identification, rare and endangered species conservation and sustainable utilization of animal resources.
