To explore the state of domestic academic research on hospital administration, the authors, using the descriptive statistical method, investigated the literature on hospital administration included by CBMdisc from 1980 to 1998. The results are as follows. In the past 19 years, the output of literature on hospital administration has been growing steadily. The distribution of such literature has been rather dispersed. There lacks a specialized and ampre- hensive database of such literature. Chinese Journal of Hospital Administration and Chinese Hospital Administration are two major professional periodicals devoted to literature on hospital administration, publishing one fifth of the literature in this aspect. And Chinese Journal of Hospital Administration, the chief and most important key periodical devoted to literature on hospital administration, has become a professional periodical which is indispensable and of first choice to hospital administration personnel.

This study aimed to modify the mixed and purified culture of rat retinal ganglion cells (RGCs) in vitro. The retinae of 1-3 day old Sprague-Dawley (SD) rats were separated bluntly into two layers: inner layer and outer layer, under a surgical microscope. Retinal cells isolated from different layers (inner layer, outer layer and whole retinal tissue) by using enzyme dissociation method were cultured in F12/DMEM medium containing 15% FBS. After 3-day culture, the RGCs in the retinal cells obtained from mixed culture of inner, outer, and whole retinal tissue were identified by immunocytochemical staining of Thy-1.1, and the rate of RGCs to retinal cells (RGCs%) was calculated. Two monoclonal antibodies, anti-macrophages/granulocytes (OX-41) against rat macrophage and antibody against rat Thy-1.1 (OX-7), were used to purify RGCs by either a conventional or modified two-stepped immunopanning procedure (purification in situ). Purified RGCs were seeded at different cell density and cultured in F12/DMEM medium containing 15% FBS. Immunocytochemical staining for Thy-1.1, MTT, and PI-Hoechst33342 fluorescence imaging were used to identify the purity and the viability of RGCs in purified culture of RGCs. The results showed: (1) Immunocytochemistry of different retinal tissue layers culture revealed that the RGCs% was (19.9±1.2)%, (0.5±0.2)%, and (6.2±1.7)% respectively in the mixed culture of inner, outer, and whole retinal tissue, with differences being significant (P<0.05); (2) fluorescent double staining of Hoechst33342 and PI indicated that with the same RGCs%, RGCs obtained from purification in situ grew well with more neurite outgrowth than those by the conventional two-stepped immunopanning method; (3) the viability of purified RGCs seeded at high density was increased and the cells developed complex intercellular networks. The viability of RGCs was declined with the decreasing seeding density, and most cells presented round or oval in shape with thin neurites. It was concluded that: (1) RGCs% in the inner layer retina was higher than that in the outer layer retina; (2) RGCs obtained by in situ purification had more neurite outgrowth and lower mortality than those by conventional two-stepped immunopanning procedure; (3) the viability of purified RGCs could be increased by increasing cell seeding density to some extent.

OBJECTIVETo discuss the mechanism of the traditional Chinese medicine Keyouling oral liquid in the treatment of condyloma acuminatum(CA) and the adjustment of cellular immunity function.

METHODSThe IL-18 and TNF-alpha levels of peripheral serum and wart tissue of patterned rats and CA patients exposed to Keyouling were determined by means of double-antibody sandwich ELISA, and the NK cellular activity of the spleen of the patterned rats and that of the peripheral blood of the CA patients exposed to Keyouling were determined by means of 3H-TdR isotype release.

RESULTSThe IL-18 and TNF-alpha levels, the NK cellular activity of the high-dosage group showed significant difference from those of the pattern group and low-dosage group in animal experiment(P < 0.05); the IL-18 and TNF-alpha levels of peripheral serum and wart tissues, and the NK cellular activity of the peripheral blood of the treatment group showed significant difference from those of the control group after treatment(P < 0.01, P < 0.05).

CONCLUSIONSKeyouling oral liquid has significant positive adjusting effect, which can markedly ameliorate the cellular immunadeficiency of the patterned animals and reinforce the cellular immunocompetence of CA patients.
