Qualified personnel are the source of social wealth and they are also the most active factor of the productive force. Nevertheless, planned economy severely hampers the initiative of the people working at institutions of higher learning. This article explores how the engagement system should be established so as to meet the needs of higher education. It is necessary to exert the market mechanism, carry out the principle of publicity, equality and competition, and choose the excellent ones by smashing the out-of-date management methods., and building a good environment where talents could demonstrate their ability, as a result, encourage the others. The current social insurance system should be reformed and set up the corresponding ones serving as guarantee of the personnel reform.

The engagement system for all college staff has been imperative in the consistent deepening reform of personnel system in colleges and universities.This paper theoretically and practically discusses some specific issues met on the process of the reform from 5 aspects.

Objective To analyze mutations in the Wilms tumor gene (WT1) in Ieukemogenesis.Methods WT1 gene in peripheral blood was determined by PRC-SSCP technique,in 32 cases of acute leukemia,included 9 cases of acute granulocytic leukemia,8 cases of chronic granulocytic leukemia(mean age-33 years) and 16 specimens of normal subjects were also detected.Results Mutations in the WT1 gene in 3 of 32 leukemias were found .WT1 mutations were found in 11% of cases of acute lymphoblastic leukemia and in 13% of cases of acute myeloid leukemia,in which they were associtated with a poor response to chemotherapy.Conclusions The mutations in Wilms tumor gene WT1 are associated with leukemogenesis and its therapy,which WT1 transcripts may prove a significant tumor marker, as a MRD monitor in evaluating remission status and early relapse,and may be useful in prognosis of acute leukemia.

OBJECTIVE:To provide a new management mode for the rational use and standardized management of narcotics in hospital.METHODS:The fingerprint management system of narcotics was build up and applied.RESULTS:The fingerprint management system of narcotics could accurately help identify patients' identity and provide effective supervision for using narcotics.CONCLUSION:The fingerprint management system of narcotics can replace the current management mode for it makes up the shortage of the traditional management system.

OBJECTIVE: Epileptic attack can cause neuronal damage and increase the risk of potential seizure. Analysis of the possible mechanism of neuronal damage following epileptic seizure may provide evidences for implementing preventive measures against brain damage due to epileptic seizures.DATA SOURCES: A computer-based search of the related publications in PubMed database between June 1995 and June 2004 with different combinations of the key words of "epilepsy", "neuron damage", "necrosis"and "apoptosis", limiting the results to the language of English.STUDY SELECTION: The retrieved articles were examined at first to select reports of experimental study on human and animals related to epilepsy and the subsequent neuronal damages, and their full-text publications were obtained with the other unrelated articles excluded.DATA EXTRACTION: Eighteen articles documenting randomized controlled experiment immediately related to neuronal damage after epilepsy seizure, 4 reporting non-randomized controlled experiments related to central neuronal excitatory toxic damage, and 3 concerning neuronal damage were collected for this review.DATA SYNTHESIS: In the 14 randomized controlled experiments, chemical or electric methods were used to induce epilepsy in the animal models in which the ultrastructural changes of the neurons and cell organelles were observed and the expression of apoptosis-related factors determined.In the 4 non-randomized controlled experiments, central neuronal ischemic and hypoxic models were adopted for observing the expression of various apoptotic factors in the neurons due to different damages with the assistance of electron microscope, to provide direct evidences for the mechanism of central neuronal excitatory toxic damage. The other three related literatures introduced the pathways of neuronal damages and the expression of the related factors.CONCLUSION: Neuronal death after epileptic seizure is correlated with the severity of the damage and mitochondrial functional status, and the mitochondria constitute the control center for neuronal survival. The release of cytochrome C and the activation of caspases are the final common pathway of neuronal damage.

Talent introduction is of great significance for the development of universities and for the raising of the academic standards.Talent introduction in general includes three links,namely,planning,the policy supporting and the concrete implementation.In the supporting policies of the talent introduction various relations should be properly handled,such as the new talents and the old talents relations,the relationship between the introduction and cultivation and the relationship between the high-level personnel and the conventional talents.
