Objective To establish the charge nurses'evaluation system and evaluate their work by comprehensive index to make the assessment more scientific.Methods The comparison value of different assessment factors were established by 4 rounds of expert consultations by the analytic Hierarchy Process (AHP)and Delphi method.The index weight was confirmed and passed the coherence test(CR＜0.01).The combined index weight and comprehensive index were also obtained.Results The charge nurses'evaluation system containing 4 one-dimension targets(including internal nursing quality,patients satisfaction degree,individual professional spirit and study and development)and 17 two-dimension targets were set up.Conclusion The combination of AHP and Delphi method supplied a simple and prompt evaluation model though currently it is difficult to estimate management personnels objectively and fairly.

It has been widely recognized that bone mineral density (BMD) is one of the best predictors of osteoporosis. Sex hormone status clearly affects bone either directly or indirectly. A longer estrogen exposure appears to be a major determinant of postmenopausal BMD and cardiovascular disease(CVD). However, there was insufficient evidence to draw conclusions that BMD might be used as a predictor factor of the risk of CVD. Therefore, the aim of the review was to examine the existing evidence on the association between BMD and risk of CVD, and to address the issue of a putative common pathogenic factor of estrogen deficiency.

Objective To investigate the cognition and participation on organ donation in ICU medical staff and analyze the influencing factors, thus to provide reference for the development organ donation promotion measures. Methods 265 ICU medical staff were chosen by convenient sampling method from 10 three-level hospitals in Chongqing and were investigated with a self-designed questionnaire about the cognition, willingness and its influencing factors towards organ donation. Results ICU medical staff′s understanding of brain death, significance, basic conditions and concepts of organ donation were 67.2% (178/265), 61.1% (162/265), 60.0% (159/265), 55.8% (148/265) respectively, but understanding of Principles , registration methods, laws and regulations, and procedures of organ donation were 24.5%(65/265), 12.1%(32/265), 7.9%(21/265), 4.5%(12/265) respectively. 47.5%(126/265) ICU medical staff were willing to donate their own organs, 35.8%(95/265) were consented to relative′s organ donation and 4.5% (12/265) were organ donation applications. 89.1% (236/265) were affected by traditional ethical concepts, 70.2%(186/265) were for the publicity not enough, 51.7%(137/265) did not know about the procedures of organ donation, 37.0%(98/265) were for too much troubled procedures, and 43.8%(116/265) were for the ineffective work of relevant organizations. Conclusions Lacking in-depth understanding of organ donation and low willingness to donate organs in ICU medical staff in Chongqing. Mainly associated with the effect of traditional concept and lack of propaganda to the donation.

Objective To investigate the clinical curative effect of titanium microplate to repair and fix obsolete cracky orbital fracture.Methods According to the diagnosis of CT scanning and three-dimensional imaging, 20 cases of obsolete orbital fractures were repaired and fixed by using titanium microplate along fracture lines. The microplates were placed according to the part nad shape of fractures. For the part of comminuted fractures, the two ends of fractures were fixed like a bridge. Results After the repair and fixation of titanium microplate, facial deformity became recuperative completely, eye-ball-movement and mastication function were recovered. During 6~12 months follow-up period, no reject reaction or cracking or dropping of microplate occured.Conclusions The titanium microplate can make orbital fractures rigid and internal fixed, and the procedure is simple and easy mastered. Therefore, it is one of the most effective materials in the repair and fixation of orbital and facial fractures.

BACKGROUND: The influencion the environment on a culture is expressed via four routes. (1) the nature of the substrate or phase on or in which the cells grow (2) the physicochemical and physiological constitution of the medium, (3) the constitution of the gas phase, and (4) the incubation temperature. Melanization is closely related to the constitution and amounts of amino acids in the medium. OBJECTIVE: The aim of this study is to investigate whether there are some differences of proliferation and melanization in cultured B,F, mouse melanoma cells according to different culture media. METHODS: We examined the color of cell pellet, cell morphology, electron microscopic findings, cell counts and melanin conlensin BgF mouse melanoma cells cultured in Dulbeccos modified Eagles medium(DMEM), F-10, MCDB 153, Minimal essential medium(MEM), and RPMI 1640, respectively. RESULTS: 1. The color of cell pellet., ringed from dark gray to light brown. The order of the darkness was DMEM, MEM, RPMI 1640, MCDB 153, and F-10 medium. 2. Most Bg, mouse melanoma cells had an epithelioid morphology, but a few cells in MCDB 153 medium showed dendrites. On the 4th day after culture, the cells in F-10 medium were larger than those in the other media. 3. In the electron microscopic. findings, BF, mouse melanoma cells in DMEM and MEM con tained numerous stage IV nelanosomes, however, those in RPMI 1640 and MCDB 153 medium contained a few, and those in F-10 medium did few. 4. The number of BF, mouse melanoma cells were 1.42 + 0.06 x 10", 1.42 + 0.12 x 10", l. 17 + 0.08 x 10, 0.73 0.06 x 10, 0.32 0.01 x 10, in RPMI 1640, DMEM, MEM, F 10, and MCDB 153 medium, respectively. 5. In the MTT assay, the order of the optical density of B,F, mouse melanoma cells in various media was as followings, DMEM, RPMI 1640, MEM, F-10, and MCDB 153. 6. Compared with the melanin contents of B;F, mouse melanoma cells in DMEM, they were 77.97% in MEM, 67.91% in RPMI 1640 and MCDB 153 medium, and 55.94% in F-10 medium. CONCLUSION: The phenotypic changes of BF, mouse melanoma cells were induced by various culture rnedia and were reversilvle. Since the phenotypes of cells can be changed by the culture media, researchers should choose the appropriate culture medium for the cells.

Very low-density lipoprotein receptor(VLDLR)is a transmembrane lipoprotein receptor and plays an important role in the disorder of lipid metabolism in diabetes.The finding of changes in expression and distribution of two subtypes of VLDLR in diabetes as well as the effective VLDLR gene therapy in hyperlipidemia have drawn attention to the VLDLR as a potential target for prevention of abnormal lipid metabolism in diabetes.

Objective:To evaluate the significance of the combination of rheumatoid factor (RF) and anti-filaggrin antibodies (AFAs) in the diagnosis of rheumatoid arthritis (RA). Methods:Sera from 266 RA patients and 186 controls were studied. RF and some kinds of AFAs (including antikeratin antibodies, anti-perinuclear factor and anticyclic citrullinated peptide antibodies) were detected using immunofluorescence and ELISA respectively. The distributions of these antibodies were compared to determine the significance of the combination of RF and AFAs. Results:The sensitivity and secificity of RF for the diagnosis of RA were 65.8% and 81.8% respectively, as compared with those of anti-CCP or RF positive were 86.5% and 80.6% respectively. Only a slight change was found in the secificity and negative predictive value between them. RF could not be detected in 91 patients while 64.8% of them could be found to have at least one kind of AFAs. Conclusion:AFAs, particular anticyclic citrullinated peptide antibodies, could be helpful for the diagnosis of RA especially in RF-negative patients.

Objective From the angle of electrophysiology, go further into the mechanism of action of acupuncture treatment to the insufficient blood-supply of vertebral basilar artery and at the same time, make a comparison of the effects between the acupuncture on cephalic meridian points and zonation cephalic acupuncture. Methods Through the contrast before and after adopting the self-acupuncture on the testees of 28 cases (including healthy persons of seven cases and TIA patients of 21 cases), observe the change of immediate effect of all waves latent period values of BAEP. Results The BAEP wave latent period of healthy persons (exclusive of I wave of auditory fainting region) assumes a relative delay within the physiological range and by comparison between points and region, the delay of V-wave Baihui point is evidently higher than that of auditory fainting region. However, the latent period of all waves of TIA patients is relatively moved up, especially there are evident differences before and after the I-wave acupuncture is carried out. Viewing from the comparison between points and region, there is no significant difference. Conclusion The function of acupuncture lies in the adjustment of antagonistic body state and it is most effective under the pathological state. Acupuncture will play the main role of excitation to the auditory nerve conduction of BAEP of TIA patients (from cochlea to midbrain) and the influence over the peripheral nerves is more sensitive than over the center ones. Although points and region have their own relative specificities, there is no significant difference between them.

Objective To evaluate the diagnostic specificity and sensitivity of anti-p68 antibody in rheumatoid arthritis (RA), and to analyze the relationship between anti-p68 antibody and the activity of RA . Methods Anti-p68 antibody was tested in the serum of 183 RA patients and 195 controls by indirect immunofluorescence (IIF). The clinical characteristics of RA between anti-p68 positive group and negative group were compared. Results ① The positive rate of anti-p68 antibody was 67.8% (124/183) in RA, 14.9% (17/114) in other rheumatic diseases and none in normal controls (0/81). Anti-p68 antibody was different from other auto-antibodies found in RA. ② Its sensitivity was 67.8% and specificity was 91.3% for RA, positive prediction rate was 87.9% and negative prediction rate was 75.1%. ③ There was statistic difference between the positive group and negative group in disease duration, RF and degree of X-ray changes. Conclusion ① Anti-p68 antibody is a new and specific serum maker for diagnosis of RA. ② The antibody is correlated with disease duration, RF and X-ray changes.
