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).

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.

Objective To explore the impact of curcumin on antistreptolysin“O”(ASO)and interleukin 8 (IL-8)level changes in serum of psoriatic mice model induced by phorbol ester(TPA).Methods 132 SCID mice were selected and divided into three groups.43 mice in normal group, 46 mice in model group,and 43 mice in intervention group.The mice of model group and intervention group were set up psoriasis model induced by TPA. Mice of the three groups were bred in the same environment,curcumin was injected in the intervention group mice,0.02 g/100 g,once a day,two weeks for a period of treatment.ASO and IL-8 level were compared amorg the three groups of mice after treatment.Results Before the treatment,compared with the normal group,positive rate of ASO in model group and intervention group increased significantly,and the difference was statistically significant (P<0.05 );after treatment,the level of intervention group was significantly lower than model group,and the difference was statistically significant (P<0.05 );before the treatment,compared with the normal group,IL-8 level in intervention group and model group increased significantly,and the difference was statistically significant (P<0.05 );after treatment,level of the intervention group was significantly lower than model group,and the difference was statistically significant (P<0.05).Conclusion Curcumin could effectively reduce ASO and IL-8 level in serum of psoriatic mice model, improve the clinical symptoms of psoriasis mice,it is an effective drug for treatment of psoriasis.

Objective To establish the optimal extraction technology for Yishen Jiangu Granules.Methods The orthogonal test was employed for selecting the optimum of extraction technology. The investigation factors were the consumption of water, the times and time of extraction. The extraction technology of Yishen Jiangu Granules was screened by the transfer rate of icariin in herb epimedii and yield of extraction.Results The best extraction condition was as follows:10 times of water, extracted for 3 times , each time was 3 h,2 h and 2 h. Conclusion This extracting technology for Yishen Jiangu Granule was objective, feasible, stable,reasonable and with good reproducibility.

Objective To establish the optimum preparation process for Yinxingye Dropping Pills. Methods The preparation conditions, such as different kinds of primary substance, cooling agent, the proportion between the extracts and primary substance, etc, were studied with L9 (34) orthogonal design. Results At the following conditions could the best was 30 d/min, dropping distance was 8cm, and cooling temperature was 10℃. Conclusion This preparation process was suitable for both laboratory test and industrial production for Yinxingye Dropping Pills.

The ISO9000 family standards developed by the international organization are the international quality standards which are widely used in various types and sizes of organizations.At present,the graduate student management method introduced by our country plays a certain positive role in guaranteeing the graduate students quality,but it still lacks effective quality control and has not formed the perfect quality management system.Through the analysis of the status quo of the development of graduate education and the problems need to pay attention to in the ISO9000 family standard procedure,document and other factors as well as the construction of the ISO9000 family standard,we put forward goal elaboration,regular staff training and other measures.

There is a wide variety of diseases resulting in pediatric right heart failure because of children′s special disease spectrum,the main mechanisms include pressure or volume overload,myocardial lesions and arrhythmia,etc.On the basis of adult studies,tailored treatment should be considered in pediatric patients.

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.

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.
