With the aging of population, cerebral small vessel disease has attracted more and more attention. A growing body of literature has confirmed that retinal vascular changes can be used as a potential marker for the prediction of cerebral small vessel disease. The retina is recognized as a window into cerebrovascular and systemic vascular conditions. Combining traditional fundus photograph and fundus fluorescein angiography with optical coherence tomography angiography, the retinal vascular system of patients with cerebral small vessel disease can be comprehensively analyzed. This paper summarizes and analyzes the application of retinal angiography technology in different image types of cerebral small vessel disease and makes a review, in order to provide reference for the early diagnosis and prevention of cerebral small vessel disease.

This study is to investigate the inhibitory effect of kaempferol on inflammatory response of lipopolysaccharide(LPS)-stimulated HMC-1 mast cells. The cytotoxicity of kaempferol to HMC-1 mast cells were analyzed by using MTT assay and then the administration concentrations of kaempferol were established. Histamine, IL-6, IL-8, IL-1β and TNF-α were measured using ELISA assay in activated HMC-1 mast cells after incubation with various concentrations of kaempferol (10, 20 and 40 µmol.L-1). Western blot was used to test the protein expression of p-IKKβ, IκBα, p-IκBα and nucleus NF-κB of LPS-induced HMC-1 mast cells after incubation with different concentrations of kaempferol. The optimal concentrations of kaempferol were defined as the range from 5 µmol.L-1 to 40 µmol.L-1. Kaempferol significantly decreased the release of histamine, IL-6, IL-8, IL-1β and TNF-α of activated HMC-1 mast cells (P<0.01). After incubation with kaempferol, the protein expression of p-IKKβ, p-IKBa and nucleus NF-κB (p65) markedly reduced in LPS-stimulated HMC-1 mast cells (P<0.01). Taken together, we concluded that kaempferol markedly inhibit mast cell-mediated inflammatory response. At the same time, kaempferol can inhibit the activation of IKKβ, block the phosphorylation of IκBα, prevent NF-KB entering into the nucleus, and then decrease the release of inflammatory mediators.

4.How to improve the survival of the fetal ventral mesencephalic cell transplanted in Parkinson's disease?
Neuroscience Bulletin 2007;23(6):377-382
It has been extensively confirmed that fetal ventral mesencephalic cell (VMC) transplantation can ameliorate the symptoms of Parkinson's disease (PD). But there are still several problems to be resolved before the extensive clinical application of this technology. The major limitations are the poor survival of grafted dopamine (DA) neurons and restricted dopaminergic reinnervation of host striatum. Some attempts have been made to solve these problems including use of some trophic factor and co-transplantation with neural/paraneural origins. The purpose of this review is to overview advances of the means improving the survival of grafts and their current limitations.

Objective To compare the effect of difierent combinatio of mannitol, furesemide and albumin in reducing intracranial pressure in 451 patients with severe traumatic brain injury (sTBI). Methods A total of 451 patients with an admissiou Glasgow Coma Scale of or less from 5 medical centers were randomly divided into 5 groups, ie, Group A(250 ml 20% mannitol each time as control), Group B(125 ml 20% mannitol each time), Group C(alternate use of 250 ml 20% mannitol each time or 40 mg furosemide), Group D(alternate use of 125 ml 20% mannitol each time and 20 mg furosemide)and Group E(alternate use of 125 ml 20% mannitol and moderate or large dose of albumin). We monitored intracraniai pressure continuously and observed the changes of intracranial pressure, electrolytes, hemato-crit and renal function after use of 5 combinations of mannitol. Furosemide and albumin. Results Man-nitol and furosemide could independently reduce intracranial pressure after 1-3 hours (P<0. 05). Semis mannitol plus furosemide or albumin could more signifieantly reduce intracranial pressure, with statistical difference compared with full dose of mannitol. Semis mannitol and alternate use of mannitol and furose-mide in aspect of intracranial pressure reduction and persistence time(P<0. 05). Alternate use of man-nitol and furosemide begot higher incidence rate of electrolyte abnormality, compared with the other com-binations (P<0. 05). Rebound rate of intracranial pressure was higher in full dose of mannitol than other combinations (P<0. 05). Incidence of renal function abnormality was higher in combination involved al-bumin than alternative use of mannitol and furosemide as well as combination of semis mannitol and furo-semide (P<0. 05). Abnormality of electrolyte and renal function wag reversible. Conclusion The use of 125 ml 20% mannitol each time plus 20 mg furesemide is more reasonable than other combina-tions. Meanwhile, semis mannitol combined with moderate or large dose of albumin has certain advantages too.

OBJECTIVE:
To investigate the changes of electrode impedance, THR/MCL values, and dynamic range (DR) in Combi 40+ cochlear implant after implantation.
METHOD:
A respective study was carried out collecting 20 consecutively implanted children's electrode impedances, THR/MCL values, and DR at seven time point during the first three years after implantation. Their variation and correlations were analyzed.
RESULT:
Overall, electrode impedances were lowest during the operation, and significantly rise to the highest at the first stimulation, then followed by a gradual decrease. After three months, electrode impedance of apical and medial cochlear segment were basically stable, while that of the basal segment was gradually increased. Dynamic range (DR) of apical and medial group electrode increased early after the operation and showed a stabilization from the second year, whereas that of basal group have a downward trend since the first year. However, the electric charge of each group increased significantly after three months, and then become stable after first year. Otherwise, a stronger negative rectilinear correlation was found between impedance changes with DR than with THR/MCL level.
CONCLUSION
The electrode impedances vary clue to different electrode position. Measuring the electrode impedance can effectively evaluate the working status of Combi C40+ cochlear implant. The dynamic range of the electrode was negatively correlated with the impedances, which made it possible to predict the width of the dynamic range by measuring the impedance 3 or 6 months after operation.
