ObjectiveTo explore salivary concentration of carcinoembryonic antigen (CEA),interleukin (IL)-6,IL-8 in oral squamous cell carcinoma and its' clinical significance.MethodsForty-two cases with oral squamous cell carcinoma were selected as experience group and 50 healthy persons as control group.ELISA method was performed to detect CEA,IL-6,IL-8 level of salivary and serum in two groups.ResultsThe salivary concentration of CEA,IL-6 and IL-8 was (62.37 ± 20.80)μ g/L,(79.12 ± 30.26)ng/L,( 834.61 ± 231.85 ) ng/L respectively in experience group,(25.72 ± 12.65 ) μ g/L,(0.58 ± 0.25 ) ng/L,(209.71 ± 67.92) ng/L in control group.There was significant difference between two groups(P< 0.01 ).The serum concentration of CEA,IL-6 and IL-8 was(61.15 ± 23.69)μ g/L,(58.17 ± 12.83) ng/L,(852.31 ±172.97) ng/L respectively in experience group,and IL-6 level of serum were much lower than that of salivary (P < 0.05).ConclusionsCEA,IL-6 and IL-8 can be biomarkers of oral squamous cell carcinoma.Salivary detection is an ideal auxiliary diagnosis method for its simplicity and sensitivity.
6.Research progress in the organic cation transporters
Journal of Central South University(Medical Sciences) 2011;36(10):913-926
The organic cation transport systems were initially recognized in studies of renal elimination.A variety of endogenous and exogenous compounds that are harmful to the body are eliminated from the kidney via glomerular filtration and/or active tubular secretion.Among those compounds are polar organic cations that require a transporter-mediated process to cross cellular membrane and be eventually excreted into the urine.The organic cation transport systems in the kidney have been recognized for several decades.Following the insight gained from the kidney,organic cation transporters (OCTs) have also been characterized in other tissues.In particular,the OCTs in the liver and in the intestine have been proposed as important determinants of drug absorption and disposition.Over the past several decades,the mechanisms of organic cation transport have been extensively characterized using in vivo models,ex vivo organ perfusions,in vitro tissue preparations and cell lines.In particular,the molecular cloning and characterization of OCTs have remarkably increased our knowledge of this important subfamily of solute carriers.In this article,we first review the molecular cloning and characterization of OCTs.We will then describe their transport mechanisms,tissue distribution and localization,and their specificity of interaction with organic cations.Regulatory mechanisms and genetic animal models will be reviewed as they provide the most important insight on this class of transporters in recent years.Finally,we will summarize genetic variation in human OCT genes and raise clinical perspectives on these important transporters.

International Journal of Pediatrics 2015;42(1):28-30,34
Interferon regulatory factor 5 (IRF-5) can induce the expressions of IFN-α,IFN-β and promote the secretion of cytokines,including IL-6,IL-12 b,IL-17,IL-23,TNF etc.IRF-5 is involved in the process of immune response,cell growth,cell differentiation,cell apoptosis,tumorigenesis and cell signal transduction.For that reason,IRF-5 plays an important role in the occurrence and progress of many diseases in humans.Further studies of IRF-5 will better elucidate the pathogenesis of related diseases and provide theoretical basis for treatment of these diseases and the corresponding therapeutic targets.
10.THE ORIGIN AND TERMINATION OF THE RETICULOSPINAL TRACT IN THE CAT——HRP METHOD
Acta Anatomica Sinica 1955;0(03):-
The origin and termination of the reticulospinal tract were studied with HRP technique in ten cats by injecting HRP into the spinai dorsal horn or gray matter on one side of the cervical or lumbar enlargement, It was discovered that the reticulospinal neurons were located not only in the medial part of the medullopontal tegmentum, but also in its lateral part. There were also a few scattered labeled neurons in the reticular formation of midbrain. The reticulospinal tract ended in the spinal dorsal horn as well as in the ventral horn. The reticulospinal tract mainly originated from the ventromedial part of the medulla and pons. In this region the labeled cells were most numerous in the nucleus gigantocellularis, less in the nucleus medulla oblongatae centralis subnucleus ventralis and the nucleus pontis centralis caudalis, and much less in the nucleus pontis centralis oralis, the nucleus paragigantocellularis laterlris and the paramedium reticularis subnucleus ventralis. Occasionally a few scattered abeled cells could be seen in the nucleus cuneiformis. The reticulospinal fibers from these nuclei projected bilaterally to both cervical and lumbar enlargments of the spinal cord except that the nucleus cuneiformis projected bilaterally to the cervical enlargement only.Two groups of labeled cells were found in the ventrolateral part of the medullary and pontal reticular formation, corresponding to the position of group A 1 and A 7 of noradrenergic neurons respectively.The reticulospinal tract derived from the medial part of the brain stem terminated predominately in the gray matter ventral to the spinal dorsal horn, but a few of them ended in the dorsal horn. These connections provide direct pathways for the control of motor and sensory functions of the spinal cord by medial reticular formation.It has been proved by Brodal with chromatolysis techenique that every cell in the nucleus paramedium reticularis sends its efferent fiber to the spinal area of cerebellum, but in this study labeled cells were found in e nucleus paramedium reticularis subnucleus ventralis. We suppose that the axons of these labeled neurons may be divided into two branches, one projecting to the cerebellum and the other to the spinal cord.It is noteworthy that we also found some labeled neurons in the nucleus medullae oblongatae centralis subnucleus dorsalis and nucleus parvocellularis, the so called "receptive region" of the reticular formation. The fibers originating from this region terminated in the spinal dorsal horn mainly, suggesting that this tract probably influences the sensory function of the spinal cord. It seems that the conception of the lateral reticular formation of the brain stem as a pure "receptive area" of the reticular formation may have be modified.
