Objective To describe the experience of nurses in combined care program of traditional Chinese medicine (TCM) and provide references for nursing managers. Methods The phenomenology research method was adopted in this study. Fourteen nurses who had achieved the combined care program of TCM participated in an in-depth interview. Data were analyzed by using phenomenological analysis. Results All nurses approved nursing program of TCM: finding sense of belonging in nursing work;demonstration of self-value;standardization of nursing tednnique;harmonious environmont of nursing work. But some defect still existed: too subjective evaluation item of nursing program of TCM;inappropriate evaluation table;lact of hospital characteristics of TCM nursing;deficiency of TCM knowledge. Conclusion Nursing managers should pay more attention to nurses' emotional experience, grasp the implementation of the problems during the program and improve the program, optimize the skills, provide trainings.

OBJECTIVE To investigate the epidemiology of fungemia and provide evidence for clinical therapy.METHODS A retrospective survey was done with the 69 cases of fungemia in our hospital from Jan 2004 to Dec 2008.RESULTS More than 65% of the patients suffered from two and more underlying diseases.Over a half of infections were developed following placement of catheters.And all of the patients had a history of antimicrobial agents use before blood culture.53(76.8%) cases were associated with Candida spp.Only 18 strains were C.albicans.The mortality rate of fungemia was 44.9%.Different Candida species had different resistance rates to antifungal agents.CONCLUSIONS Fungemia patients often have serious underlying diseases.Most fungemia cases are candidemia caused by non-C.albicans.Some fungal pathogens are resistant to fluconazole and itraconazole.

OBJECTIVE To monitor the characteristics of distribution and drug resistance of Acinetobacter baumannii in our hospital. METHODS A. baumannii isolates were collected in our hospital from Jan 2004 to Dec 2005. Antimicrobial susceptibility testing was performed by disk-diffusion method,according to the standards of NCCLS 2004. RESULTS Totally 177 strains of A. baumannii were distributed clinically in the respiratory unit as the most ones (47 strains, 26.6%), and in ICU as the next (38 strains, 21.5%); the older the age, the higher the appearing rate; the highest appearing rate was from the sputum, up to 78.1%; more than 60% of isolates were resistant to all antimicrobial agents tested except imipenem, meropenem and cefoperazone/sulbactam. However,10 pan-resistant strains were found. CONCLUSIONS With the increasing isolation rate of A. baumannii, its drug resistance increases simultaneously.

Objective To observe the role of short-term use of megestrol acetate in reducing the toxicity of chemotherapy in breast cancer and in improving the quality of life of patients, as well as its impact on neo-adjuvant chemotherapy effects. Methods The effection of adjuvant chemotherapy, toxicity, and the quality of life of 158 patients with breast cancer were investigated by a retrospective control study. The data were statistically analysized by X~2 test. Results There was no significant difference of neo-adjuvant chemotherapy effects between Megestrol acetate + CEF chemotherapy group and vitamin C + CEF chemotherapy group (Megestrol acetate + CEF chemotherapy group was 74. 84%, vitamin C + CEF chemotherapy group was 76.15) ; Megestrol acetate + CEF chemotherapy group had more modest bone marrow suppression and gas-trointestinal reactions and better food intake, weight, KPS score than vitamin C + CEF Chemotherapy group, all the differences being statistically significant (P < 0.05). Conclusion Short-term use of megestrol ace-tate can reduce the adverse effects derived from chemotherapy of breast cancer and improve the quality of life of patients with breast cancer and had no effects on the efficacy of the neo-adjuvant chemotherapy.

BACKGROUND:During joint replacement, different materials of prosthesis can be used. Different prosthesis can produce different effects and the stress distribution of bone interface. OBJECTIVE:To explore the effects of different materials on the stress distribution and biomechanics of the bone interface of artificial hip joint. METHODS:The CT scan of the hip was carried out. The image data were saved in DICOM format and processed by MIMICS software. The 3D finite element model of the femur was obtained by ANSYS. A three dimensional finite element model of the femur was made with the material properties of the femur. Three kinds of different replacement prosthesis materials (Co Cr Mo aloy, titanium aloy and composite materials) were selected, and the specific requirements of the actual joint replacement were selected, and different types of prosthesis were designed in CAE software. In the STL format, the prosthesis model was imported into MIMICS, and the femur and prosthesis were assembled. The stress status of different prosthesis was analyzed, and the stress shielding rates of exterior and interior sides of middle and lower parts of the femur, right to and 30 mm below lesser trochanter and right to lesser trochanter of the proximal femur were calculated. RESULTS AND CONCLUSION:Through three-dimensional finite element analysis, a direct and accurate model of the femur and the three-dimensional model of the prosthesis were established. According to the actual situation, material assignment of the femoral three-dimensional finite element model was conducted to obtain the corresponding model. Thus, the properties of different materials of the femur were shown visualy. The femoral stress of cobalt chromium molybdenum aloy, titanium aloy, and composite material was simulated after replacement. Results found that the stress shielding rate can decrease in the middle and lower parts of the femur. After replacement, the femoral stress is higher than that of the intact femur. The experimental results show that the stress shielding of the joint was performed after joint replacement with Co Cr Mo aloy, titanium aloy and composite materials. Among them, the composite material is more close to the actual physiological environment of the human body, and it can better reduce the stress shielding effect, and is beneficial to the stress from the prosthesis to the femur.

Objective To investigate correlation between post-stroke depression (PSD) and multiple factors during onset of acute cerebral infarction. Methods Depression was measured with Hamilton Depression Rating Scales (HAMD) in 58 patients with acute cerebral infarction, and their neurological function were evaluated by neurological function defect (NFD) score. Their immunoglobulin G (IgG) index was calculated and level of nitric oxide (NO) in cerebrospinal fluid (CSF) was measured. Lesion and nature of cerebral infarction in 58 patients with acute stroke were located by CT. All the data were statistically analyzed with student-t test and ? 2 test, as well as linear regression model. Results Seventeen of 58 patients of stroke appeared PSD with an occurrence rate of 29.3%. Occurrence rate of PSD was significantly higher in patients with cerebral infarction than in those with cerebral hemorrhage  2=4.86, P

Objective To investigate the effect of estrogen receptor ?(ER-?)on the formation of mice endometriosis.Methods Endometriosis animal model was established with 30 ER-? knockout(?ERKO)mice and 22 ER-? non-knockout(?ER)mice.All the mice were divided into three groups:intact group(?ERKO 10 and ?ER 8),ovariectomy group(?ERKO 10 and ?ER 7)and ovariectomy + estradiol treatment group(?ERKO 10 and ?ER 7).The endometriotic grafts were taken out from all the mice 2 weeks after operation,and the weight,histological structure and the expression of MMP-9 in the grafts were analyzed and compared between ?ERKO and ?ER mice.Results The endometriotic grafts were significantly heavier 2 weeks after transplantation than that before transplantation in intact group(P0.05).In addition,no significant differences were found between the ?ERKO and the ?ER mice in endometriotic grafts' weight,the histopathologic structure and the expression of MMP-9.Conclusion ER-? may throw few influence on the formation of endometriosis.
