ObjectiveTo study the effect of ginsenoside Rg1 on the pathological changes of rat optic nerve injury. MethodsThe model of rat optic nerve injury was established, the rats were divided into the experimental group and control group,intraperitonealiy injected ginsenosides Rgl (10mg/kg) to experimental group of rats for 20days ,meanwhile intraperitonealiy injected the same volume of saline to the control group,took eyeball and optic nerve from the optic nerve injury eye and the normal eye in both groups ,HE staining,SABC immunohistochemical staining of Bcl-2, neurocan were analyzed. ResultsHE staining results showed the morphological difference on optic nerve cells from control group and the optic nerve injury group. Immunohistochemistry showed the neuronal cell apoptosis was significantly increased after optic nerve injury. The intraperitoneal injection of ginsenoside Rg1 could significantly improve the situation of cell apoptosis. The significant increment of fiber protein may be partly related to the improvement of cell apoptosis, but the principle was not clear. ConclusionGinsenoside Rg1 had protective effect on rat optic nerve injury.

Trypanosoma is a human parasite severely affecting poor tropical areas.However,current frontline drugs for Trypanosoma treatment have severe side-effects with decreased effectiveness.Based on the fact that aminoacyl-tRNA synthetase is a bonafide drug target for several microorganisms,including bacteria and fungi,it is plausible that it may also be effective target of Trypanosoma.The Trypanosoma brucei leucyl-tRNA synthetase(tbLeuRS)was cloned,expressed and purified to develop an in vitro enzymatic assay system.The assay conditions were further optimized for the effective screening of tbLeuRS inhibitors thus establishing an anti-Trypanosoma drug screening system targeting tbLeuRS.The results indicated that this system can be employed for the effective screening of anti-Trypanosoma drugs with satisfactory specificity.In addition,this system can also be used for compound optimization,as well as IC50 testing.Using this system a series of compounds are identified that are effective Trypanosoma inhibitors without toxicity to human cells.Therefore,targeting tbLeuRS may represent a new venue for the development of anti-Trypanosoma drugs.

Background: Creatine transporter (CRTR) deficiency is the most common creatine deficiency syndrome,
of which the final diagnosis relies on mutation in the X-linked CRTR gene. To date, more than 90
mutations in the SLC6A8 gene have been reported. This paper discusses a novel mutation detected via
the thorough sequencing of all the X-chromosome-specific exons investigated in a four and a half year
old boy with an intellectual disability, speech and language delay and motor disturbance. Methods:
A brain magnetic resonance imaging (MRI) and a proton magnetic resonance spectroscopy (MRS)
were carried out, the creatine and creatinine concentrations in the urine were checked and all exons
were sequenced. Results: A detailed clinical investigation revealed a reduction in the cerebral creatine
levels in the brain by the MRS, elevated creatine and creatinine concentrations in the urine and signal
abnormalities in the left frontal cortex of the brain by the MRI. A novel change was identified in the
heterozygosity of the exon 10: c.1395-c.1401 deletion.
Conclusion: The use of a combination of powerful new technologies, such as thorough exome-nextgeneration
sequencing and a brain MRS, should be considered, in order to determine any neurometabolic
diseases, especially when the signal abnormalities in the brain MRI cannot be explained by any other
factors. This mutation results most likely in a dysfunction of the creatine transport and synthesis,
hence causing central nervous system symptoms.
