1.Problems and challenges confronting ideological and political work in hospitals
Chinese Journal of Hospital Administration 1996;0(10):-
At present ideological and political work in hospitals is characterized by limitedness, openness, autonomy and extensiveness. In doing ideological and political work in hospitals, it is therefore important to create for the staff diversified ideological platforms, extensive participation platforms, and swift and smooth information platforms. It is also essential to guide the ideological and political work in hospitals with a scientific view of development, adhere to people-oriented and scientific development, keep up with the times, constantly make innovations, and provide powerful intellectual impetus to hospital reform and development.

BACKGROUND: Formerly, it was thought that the damaged hair cells could not have the repair ability. Recent studies demonstrate that mammal vestibule hair cells also possess certain repair ability after being destroyed.Then, whether mammalia animal cochlea hair cells possess regenerative ability after being destroyed is disputed.OBJECTIVE: To observe cochlear hair cells condition and threshold value change of auditory brainstem response (ABR) at different time following gentamicin ototoxicity by using scanning electron microscope (SEM) technique combined with ABR test, so as to investigate whether cochlear hair cells of mammals can be regenerated after being injured.DESIGN: A randomized and controlled animal experiment.SETTING: Department of Physiology, Shenyang Medical College.MATERIALS: This experiment was carried out at the Hearing Research Room of China Medical University from November 2001 to May 2002. Totally 60 healthy adult white Guinea pigs, with red eyes and sensitive auricle reflex, of clean degree, were used and randomly divided into gentamicin group and normal control group with 30 guinea pigs in each one.METHODS: 100 mg/kg gentamicin was intraperitoneally daily injected into the guinea pigs, serving as gentamicin group. Same volume of normal saline (2.5 mL/kg) was intraperitoneally daily injected into the guinea pigs,serving as normal control group. All the guinea pigs were given medication for 10 successive days. Threshold value of ABR was detected respectively pre-operatively and at the 1st, 3rd, 30th days postoperatively; after withdrawal and execution, scanning electron microscope was used to observe cochlear hair cells of guinea pigs in each group.MAIN OUTCOME MEASURES: ① Threshold value of ABR. ②Cochlear hair cell change of guinea pigs at different time following gentamicin ototoxicity.RESULTS: All the 60 experimental animals entered the stage of result analysis with no loss in the midway. ①At 1,3 and 30 days after withdrawal of gentamicin, threshold value of ABR was significantly higher as compared with normal control group, with significant difference [(38.00±3.75), (2.22 ±3.63) dB nHL,t=30.651, P < 0.001];[(39.09±4.22), (2.50±3.54) dB nHL, t=29.708, P < 0.001];[(14.50±3.69), (1.50±2.42) dB nHL,t =13.175, P < 0.001]. Threshold value of ABR recovered obviously on day 30, but did not reach the normal level. ②On the first day after withdrawal of gentamicin , stereocilium of hair cells in second turn of cochlea of guinea pigs presented fusion, distortion, lodging, loss or incompetence and other pathological changes , especially severe in the third turn , also cystic form protrutions appeared outside the stereocilium of inner hair cell; On day 3 after withdrawal of gentamicin, stereocilium of outer hair cells in the second turn of cochlea of guinea pigs still presented fusion, loss, lodging and other pathological changes. Stereocilium of inner hair cell still showed lodging,but the outside cystic form protrutions decreased; On day 30 after withdrawal of gentamicin, stereocilium of outer hair cells in the second turn of cochlea presented fusion, loss , lodging and other pathological change ,which were obviously weaker than those on the 1st day and 3rd day after withdrawal of gentamicin , and at the same time , new born stereocilium appeared in the third turn of cochlea.CONCLUSION: Cochlear hair cell morphology recovery appears in those which survive for 30 days after cochlear hair cells of guinea pigs are damaged following gentamicin ototoxicity, and threshold value of ABR also recovers to some extent, suggesting that cochlear hair cells possess regenerative and repair ability following gentamicin ototoxicity. Hair cells after gentamicin-induced cochlear damage possess regenerative ability.

This paper deals with the ultrastructure of the body wall of adult Pagumogonimus skrjabini by transmission electron microscopy. Infected crabs were collected from Siyen, Hubei Provine, and adult worms were obtained from the lungs of experimentally infected dogs 90 days post-infection.The normal structure of body wall of the P. skrjabini is composed of tegument, tegument cell, musele, muscle cell and protoplasmic tubules, all of which form together syncytium.The tegument contains external plasma membrane, tegument matrix and basal plasma membrane. The cell coat in fine granules is distributed over the whole external plasma membrane surface. The tegument matrix contains various secretory bodies, vesicles and mitochondria. The tegument cell is irregular in shape. Golgi complex, ribosome, autoly-sosome are seen in the cytoplasm. There are two layers of muscle, the external circular muscle and the inner longitudinal muscle layers. The nucleus of immature muscle cell has many heterochromatins, while the nucleus of mature muscle cell is large and round in shaps. Mitochondria and glyco-gen granules are transmitted from muscle cell proper to the muscle by protoplasmic tubules (Figs. 1-7).

Currently, the basic network resource of the entire traditional Chinese medicine (TCM) industry is fragmented. Issues of data unify are not easily resolved. It seems that there is no new breakthrough in key technologies, especially on the problem of data sharing and resources' integration. In this context, a method of medical information data sharing is advocated to solve the problem. We use the RESTful style to define resources of the pharmaceutical industry, which is based on the UDDI Web services standards. The objective of this paper is to create a method of TCM resource URL defined and exchanged. Finally, this paper provided an easy way for TCM data network sharing.
