2.Expression and Regulation of Intercellular Adhesion Molecule-1 in Central Nervous System Diseases
Journal of Applied Clinical Pediatrics 2004;0(07):-
Intercellular adhesion molecule-1 (ICAM-1) is found in surface of cells in various tissues,which is a adhesion molecule with wide range of biological activity and plays an important role in inflammatory and immune response,signal transduction,tissue repair and many other physiological and pathological processes.In this paper,ICAM-1 expression and regulation in the body,as well as some actions in the pathogenesis of central nervous system diseases are reviewed.

Objective To observe age-dependent feature of damage of hippocampus to different maturational stages rats after kindling repeated seizures.Methods The effects of 5 daily pentylenetetrazol-induced convulsions in different rats beginning at postnatal day 10,20,60(P10,P20,P60)were evaluated.In the 3 groups,Thionin staining method was utilized to observe morphological changes and cell counting of dentate granule cells,CA3,CA1,and hilar neurons.Timm's method of silver sulfide staining was adopted to observe the mossy fiber sprouting.Results 1.Cell counting of CA1,CA3 and hilar neurons in P10 and P20 groups demonstrated no differences from controls in rats,whereas P60 with daily seizures had a significant decrease in CA1,CA3 neurons(8.22?1.88,5.62?1.68 vs 6.31?1.50,3.62?1.40)(t=2.246,2.587 Pa

·AIM:To report a case of entry of antibiotic ointment into the anterior chamber following sutureless clear corneal incisions phacoemulsification.·METHODS:A 62-year-old man had uneventful phaco-emulsification with clear corneal incisions with intraocular lens(IOL) implantation. Postoperative medication included antibiotic/steroid ointment; the eye was firmly patched at the end of the procedure. On the first postoperative day, the patient was seen an oily droplet floating in the anterior chamber. Immediate surgical removal of the ointment without IOL exchange was performed.·RESULTS:During follow-up for six months after irrigation/aspiration of the anterior chamber and removal of the oily droplet, visual acuity and intraocular pressure (IOP) were unchanged and anterior segment was formed and quiet.·CONCLUSION:Ophthalmic ointment may ingress into the anterior chamber through unstable clear corneal incisions. The case highlights the importance of appropriate wound construction and integrity, as well as the risk of tight eye patching following placement of ointment.

To develop a LC-MS/MS method for the determination of protocatechuic acid, protocatechuic aldehyde, salvianolic acid A, salvianolic acid B, cryptotanshinone and tanshinone II(A) in rat plasma and brain. The plasma and brain samples were precipitated with ethyl acetate, then were separated on an Agilent eclipse plus-C18 column (2.1 mm x 50 mm, 3.5 microm) using acetonitrile (consisting of 0.1% formic acid) and water (consisting of 0.1% formic acid) as mobile phase in gradient elution mode. The mass spectrometer was operated under both positive and negative ion mode with the ESI source, and the detection was performed by MRM. The transition of 154.3/153.1 m/z for protocatechuic acid, 137.3/108 m/z for protocatechuic aldehyde, 493.0/295.2 m/z for Salvianolic acid A, 718.0/520.0 m/z for salvianolic acid B, 321.4/152.3 m/z for chloramphenicol, 297.4/254.3 m/z for cryptotanshinone, 295.5/249.3 m/z for tanshinone II(A) and 285.2/154.0 m/z for Diazepam. The calibration curves in the range of 0.625-1 000 microg x L(-1) for protocatechuic acid and protocatechuic aldehyde, 1.25-1 000 microg x L(-1) for salvianolic acid A, 2.5-1 000 microg x L(-1) for salvianolic acid B, 0.15-1 000 microg x L(-1) for cryptotanshinone, 0.625-1 000 microg x L(-1) for tanshinone II(A) are with good linearityin rat plasma and brain. The analysis method is sensitive, simple, and suitable enough to be applied in the pharmacokinetic study of the 6 main components. Animal testing gives the lgBB of the drugs and further studies of the 6 components cross the blood-brain barrier can be carried out.

0bjective To observe the different brain activation of acupuncture and electroacupuncture on healthy subjects and healthy subjects.Methods The different brain activation involved in heroin addiction between healthy subjects and addicts was detected by fMRI.Acupuncture point used in present study Was Zusanli (ST 36).Results Different brain activations between healthy subjects and addicts during electroacupuncture were hypothalamus(X0,Y2,Z9,t=7.36,P<0.01),anterior cingulate(X5,Y49,Z8,t=4.11,P<0.01),tempo-ral gyrus(X61,Y12,Z8,t=3.05,P<0.01).The difference of activated regions during conventional acupuncture between healthy subjects and heroin addicts was thalamus(X2,Y16,Z12,t=2.87,P<0.01),parahippocampus (X17,Y52,Z3,t=3.14,P<0.01),and hypothalamus(X0,Y2,Z9,t=6.98,P<0.01).Conclusion Regions with significant activation detected by fMRI are different during acupuncture in heroin addicts and in the healthy subjects.Notably,the hypothalamus activation is more robust in the addicts than in the healthy subjects during ac-upuncture stimulation.

Objective To investigate the situation and progress in technology of brain computer interfaces (BCI) by using the bibliometric approach.Methods Literature searching was done in China national knowledge infrastructure (CNKI) database using keyword brain computer interface.Subsequent results were analyzed by using softwares concerning the periodical distribution,subjects' distribution,foundations,authors,institutes,journal types and key words.Results Overall 425 publications from 160 journals were included.The amount of the relevant articles showed an increasing trend in 2002 to 2012.The research in BCI in China was supported by a large amount of funds.There were a lot of Chinese authors and institutions participating in BCI study,and they were widely distributed across the country.However,only 32.56% of all authors and 51.85% of all institutions published more than 1 article.Moreover,research on BCI mainly was focused on the biomedical engineering aspect.Conclusions Research on BCI developed rapidly in the past 12 years in China and will continue to develop in the following decades.In the future studies,the focus should shift to clinical research instead of biomedical engineering,and to make this technology a useful clinical practice is the first priority.
