2.Extracelluar matrix stimulates neurite outgrowth of dorsal root ganglion neurons differently depending on whether extracted from degenerated or normal intervertebral disk
Chinese Journal of Tissue Engineering Research 2014;(7):1039-1044
BACKGROUND:Compared with the normal intervertebral disk, the density of nerve fibers and number of nerve endings and neuropeptides appear to be more in the degenerated intervertebral disk. However, this phenomenon does not occur in the normal y aged disk.
OBJECTIVE:To evaluate the axonal growth and induction of a painful neuropeptide and substance P using rat dorsal root ganglion neurons and degenerated human disc cells in vitro.
METHODS:The human intervertebral discs were harvested from patients with discogenic low back pain and normal people. And extracelluar matrix extracted from human degenerative intervertebral discs was cultured with rat dorsal root ganglion neurons. The promotion of axonal growth and induction of substance P of dorsal root ganglion neurons in extracted medium were evaluated through morphology observation and enzyme-linked immunosorbent assay, respectively.
RESULTS AND CONCLUSION:Compared with the normal group, the content of nerve growth factor in the degenerative group was significantly higher and the average length of neuritis was significantly longer in the experimental group (P<0.05). After intervention with anti-nerve growth factorβ, the average length of neuritis became remarkably shorter. The percentage of substance P-immunoreactive cells was significantly higher in the degenerative group compared with the normal group (P<0.001). Nerve growth factors that highly express in the extracellular matrix from the degenerative intervertebral dick can promote neurite outgrowth of dorsal root ganglion neurons and induce release of neuropeptides related to pain transmission.

AlM: To evaluate the effectiveness of Spot Vision Screener on vision screening of children without cycloplegia.METHODS:A total of 87 children (174 eyes) aged from 2~9 years old were examined with Spot Vision Screener and optometrist before cycloplegia.RESULTS: Statistical analysis demonstrated that the cylinder diopter and axis, the equivalent spherical diopter in both eyes, and the spherical diaopter in left eye had no significant change ( P>0. 05 ). However, the spherical diaopter in right eye had statistical significance. CONCLUSlON: Spot Vision Screener is a suitable instrument in vision screening of children without cycloplegia.

Objective To evaluate the clinical value between peritoneal lavage cytology (PLC) and prognosis of gastric cancer. Methods The peritoneal lavage fluid of 60 gastric cancer patients and 12 noncancer patients were collected,different methods were used to examine the exfoliated cancer cells,and relationships between positive results and relative clinico-pathological parameters were evaluated.Results The positive rate of PLC was 31.8%,and was positively correlated with the degree of histologic differentiation of gastric cancer (P0.05). The postoperative one-year recurrence and survival rates of the positive and negative groups were significantly different(P

ObjectiveTo investigate the intelligence characteristics and relativity with motor development of children with spastic diplegia.MethodsIntelligence and motor development of 46 children with spastic diplegia were tested by Wechsler Intelligence Scale and Motor Development Milestone (MDM), to find out difference of intelligence between the children with diplegia and the normal control group.ResultsIntelligence quotient (IQ) of children with spastic diplegia was lower significantly than the normal control, specially performance IQ (PIQ). PIQ was related with motor development. The more delayed motor development was, the more lower PIQ was. Subtest scores of animal egg, puzzle, block design and picture generalization were lower in spastic diplegic children with normal IQ than that of the normal control group, while vocabulary IQ (VIQ) was not different.ConclusionThe intelligence structure of children with spastic diplegia is imbalanced and PIQ of those children is significantly lower than the normal children, which is related to hands-eyes correspond, sight-motor correspond and speed, and space-sight ability.
