Chinese Pediatric Emergency Medicine 2015;22(1):48-51
Intestine is one of the fastest cellular renewal tissues and organs in the body cells,and intestinal mucosal epithelial cells keep self-renewal constantly all the life.Its effect relys on stem cells continued proliferation,differentiation and replaces the outer terminal differentiated cells.Under the stimulation after injury,the repairment of stem cells is initiated,the proliferation and differentiation of intestinal stem cells are stimulated throughout molecular mechanisms.Studys found that intestinal stem cells involve in the repairment of the gut during stress,trauma,anoxia,radioactive damage,inflammatory bowel disease and short bowel syndrome.In this paper,we briefly overviewed the definition,location,and differentiated regulation stem cells,and influence factors in the intestinal repairment.
3.Isolation, identification and expression of a cDNA clone encoding human GM-CSF
Chinese Journal of Immunology 1986;0(04):-
One of the human GM-CSF cDNA was successfully isolated with a new screening method. Up 1/170 of positive rate was reached. The COS-7 cells were transfected with the cDNA clone and the resulting supernants contained colony-stimulatory activities. Human GM-CSF cDNA was also subcloned into a expression plasmid pKPL-2D and the unfused recombinant human GM-CSF was expressed in E. coli. The expressed products could maintain in vitro the growth of a cell line BMU- 2 and stimulate its colony formation. In addition, it could increase the colony formation of bone marrow cells from the patients with acute non-lymphatic leukemia (ANLL).

8.Causes of Speech Retardation of Children With Normal Hearing
Journal of Audiology and Speech Pathology 1998;0(01):-
Thirty-one children suffered from speech retardation were found to have normal hearing level through ABR and/or acoustic immittance tests. Some of them were further checked by psychiatrists and pediatricians. The results demonstrate that among reasons for speech retardation in children,autism and mental retardation are important factors that can not be ignored. A-mong children with unclear diagnosis .some harmful factors were found on themselves and in surroundings. We emphasize that for children with speech retardation,not only hearing disorders,but also other factors should be considered.

Journal of Audiology and Speech Pathology 1997;0(04):-
Objective To compare the speech perception performance of BTE hearing aids with different directional microphones. Methods 20 adults with sensorineural hearing loss participated in the research. Two digital hearing aids were programmed for adaptive directional, fixed directional, and omni-directional microphone patterns. The multi-talker noise was presented in three conditions: 180?,?90?, and 360?. Each subject was tested in nine listening conditions (three microphone patterns and three noise presentations) by using modified Hearing In Noise Test. SNR was obtained in each testing condition. Results Under each noise presentation, the sequence of microphone patterns that obtained SNR from low to high was: adaptive directional, fixed directional, and omni-directional. Conclusion Adaptive directional microphone worked best when the noise source was changing or the noise was coming not only from behind but also from other directions; fixed directional microphone could be employed when the noise came from the rear; omni-directional microphone was suitable for hearing in quiet.

The study intended to evaluate the combined examination of transient flash visual evoked potential (T-FVEP) and steady-state flash visual evoked potential (SS-FVEP) in diagnosis of optic neuropathy and macular disease. T-FVEP and SS-FVEP were examined in 22 cases (29 eyes) with optic neuropathy, 8 cases (9 eyes) with macular disease and 32 cases (32 eyes) of controls. The positive rates of T-FVEP and SS-FVEP in diagnosis of optic neuropathy were 83% and 100% respectively; that of combined examination was 100%. The positive rates of T-FVEP and SS-FVEP in diagnosis of macular disease were 5/9 and 7/9, and that of combined examination was 8/9. The positive rates of combined examination of T-FVEP and SS-FVEP in diagnosis of optic neuropathy and macular disease are higher than that of T-FVEP and SS-FVEP alone, and should be used routinely in the diagnosis of visual pathway disease.
