Objective: To analyze the constitution of hospitalization expenses and provide evidence for controlling unreasonable increase of medical costs. Methods: To compare the medical expense constitution of cerebral infarction patients with and without medical insurance; interview the doctors, patients and the medical insurance managers of medical insurance, analyze the influencing factors of the expense through combining the result of interview and quantitative data. Results: The patients with medical insurance spent higher expense than their counterparts, the per capita cost of medical insurance increase by year. Through analyzing the constitution of hospitalization cost, medicine fee and examination cost are the major medical costs. Conclusion: The costs of patients with medical insurance have over-treatment problem, which could be controlled by changing payment method and strengthening management.

OBJECTIVE To observe the teratogenecity of ethylene oxide sterilized materials to cells which are used for biotherapy.METHODS Three kinds of cells were cultivated in ethylene oxide sterilized culture flasks which were conserved for different time and high temperature/high pressure sterilized vitric culture flasks.NK/CIK cells induced from cord blood,human mesenchymal stem cell and CD34+ cells were cultivated in ethylene oxide sterilized culture flasks which were conserved for one day(group A),for three months(group B),for more than six months(group C) and cultivated in high temperature/high pressure sterilized vitric culture flasks(group D).After ten days,not only the growth and morphology of cells but also the breakages fragmentations and gaps in chromosomes and replication of chromosome in nucleus were observed.According to these data,the malformation rate was calculated.RESULTS Compared with groups C and D,the inductivity of groups A and B obviously degraded(P0.05).CONCLUSIONS Compared with the control group,the materials which were sterilized by ethylene oxide and conserved for less than one day and three months can bring damage to cells.However,the damage is not discovered in the materials which were conserved for more than six months.Ethylene oxide can induce cell aberrant and mutation.Therefore,it is suggests that materials be conserved for more than six months to ensure safe and effective enforcement of biotherapy.

OBJECTIVE:To investigate the distribution and drug resistance of High-level Aminoglycoside Resistance Enterococcus spp (HLAR) in hospital infection. METHODS:The clinical specimens collected from 2004 to 2007 in our hospital were isolated by routine method. Identification of the bacteria and Antimicrobial susceptibility test were performed using automatic microbiology analysis system. RESULTS:Of the total 292 strains of Enterococcus which induced HLAR in hospital infection,Enterococcus faecalis (E.faecalis) represented 49.3% (144/292) and Enterococcus faecium (E.faecium) 41.4% (121/292). 27.4% (80/292) were from intensive care unit,17.5% (51/292) the department of nephrology and 8.9% (26/292) the neurosurgery department. The urinary system infection represented 29.8% (87/292) in hospital infection. The antimicrobial resistance of E.faecium was significantly higher than that of E.faecalis against quinolones and ?-lactamase antibiotics,but the antimicrobial resistance of E. faecalis was higher than that of E,faecium(P

Objective To evaluate the cause which leads to the allelic dropouts at D8S1179 locus while performing paternity testing with the AmpFlSTR Profiler Plus kit. Methods A singleplex amplification system for D8S1179 locus (GenBank Accession No. G08710) was used to verify the typing results by using the AmpFlSTR?Profiler plus kit. Dropout alleles were then sequenced. Results G to A transition was identified at the position of the 147th base of the GenBank sequence. The frequency of the G to A transition among the Chinese population was 0.50 X 10"2 (10 out of 2013 unrelated individuals). Conclusion The G to A transition may be located at the binding site of one of the primers of the AmpFlSTR?Profiler Plus kit. It is suggested that the G to A transition might be the cause of the allelic dropout at the D8S1179 locus.
