Objective To conduct surveys on nursing managers'pre-post training needs in the country.Methods Self-made questionnaires on nursing managers'pre-post training and the managerial skills of nursing managers in the next five years were used to conduct surveys on 1 004 nursing managers in 77 domestic hospitals.Results Among those surveyed,45.8% of the heads of nursing departments and 54.2% of the head nurses had no pre-post training while 94.5% of those surveyed deemed it extremely necessary for nursing managers to receive pre-post training.Conclusion It is essential for nursing managers to get pre-post training,which ought to be conducted at various levels,with different focal points, and according to their needs.Such training should be gradually conducted in a standardized and systematic way.

Objective To investigate the myocardium protective effect of immunoinflammatory response induced by preinfarction angina. Methods Eighty-eight patients of acute myocardial infarction were divided into preinfarction angina group (48 subjects) and sudden onset group (40 subjects). The incidence of severe arrhythmia,heart failure,cardiac shock and in-hospital mortality were assessed in the two groups. The myocardial infarction size,ventricular function,coronary angiography were compared between the two groups. Some immunoinflammatory markers levels were detected. Results In preinfarction angina group,the incidences of severe arrhythmia,heart failure,and in-hospital mortality were lower (P

Objective Among the factors affecting embryo implantation, oxidative stress is one that receives much medical attention. The purpose of the study was to explore the effect of H2 O2 on the endometrial stromal cells ( ESCs) in the decidual mouse model of oxidative stress of ESCs. Methods Primary ESCs cultured by enzymatic digestion with a mesh filter were divided into a control, an experimental, and a model group. Decidualization was induced in the mice of the experimental and model groups by inter-vention with 10 nM E2 and 1μmol/L P4 for 72 h in vitro. Then, the animals of the model group were treated with different concentra-tions of H2 O2 for 4 hours. The primary ESCs were identified by immunohistochemistry, the expression of dPRP mRNA determined byRT-PCR, the proliferation of the decidual ESCs treated with H2 O2 analyzed by CCK-8, and the level of ROS detected by flow cytometry. Results Primary mouse ESCs were successfully isolated, cultured, and identified, which were shaped like spindles and polygons, radial-ly aligned under the microscope. Immunofluorescence analysis showed positive expression of vimentin and negative expression of cytokeratin. The purity of the primary mouse ESCs was ( 96. 3 ± 0. 49 )%. Theexpression of dPRP mRNA was significantly higher in the ESCs treated with E2 and P4 than in the control (0.0002±0.0000 vs 1.0010±0.0011, P<0.01). H2O2 at ≥150μmol/L suppressed the proliferation of the decidual ESCs by 6.9% (P<0.05), and in a concen-tration-dependent manner, reaching the maximum inhibition rate of 70.6% at the concentration of 300μmol/L. The level of intracellular ROS was markedly increased in the ESCs treated with H2O2 at 50μmol/L (27.77±4.20) and 100μmol/L (43.57±6.58), with statisti-cally significant difference from that in the control group (17.47±0.61) (P=0.001). Conclusion H2O2 at 100μmol/L can signifi-cantly elevate the intracellar ROS level without affecting the proliferation of decidual primary ESCs, and therefore can be used for estab-lishing the model of oxidative stress of ESCs in decidual mice.

Objective To study the clinical characteristics, the laboratory profile (CD4+ and CD8+ counts and CD4+/CD8+ ratio) and the efficacy of antifungal treatment in HIV/AIDS patients with oropharyngeal candidiasis. Methods Oral lesions were evaluated among 20 HIV/AIDS patients with oropharyngeal candidiasis and the controls who were HIV-negative patients with oropharyngeal candidiasis. Samples were obtained from the lesions for fungal examination by microscopy and culture. The flow cytometry was used for detection of CD4+ and CD8+ counts in peripheral blood. Treatment efficacy of itraconazole was assessed among study group and the control group after treatment for one week, two weeks, at the end of treatment, as well as two weeks after treatment. Results Out of 20 HIV/AIDS patients, 19 were infected with Candida albicans and one with Candida parapsilosis. Six cases had infection on the tongue and 14 on the mucous membrane of oral cavity. CD4+ and CD8+ counts, and CD4/CD8 ratio were 119.40?127.43, 652.50?338.57 and 0.163?0.13, respectively. Mycologic clearance rates were 16.67%, 50.00%, 61.11% and 66.67%, respectively, after treatment with itraconazole for one week, two weeks, at the end of treatment, and two weeks after treatment. Conclusions Oropharyngeal candidiasis is a complication occurred in HIV/AIDS patients, and Candida albicans is the most common pathogen of the infection. The tongue and mucous membrane of oral cavity are usually involved in the patients. The therapeutic efficacy is related to the status of immunity.

Objective To establish an animal model of dermatophytosis and to evaluate antifungal efficacy on dermatophytosis with this model. Methods Animal models of dermatophytosis were established by inoculating dermatophyte suspension onto abraded skin on the back of guinea pigs. Thirty- eight healthy guinea pigs were randomly and equally divided into 2 groups, namely, Trichophyton mentagrophytes group (infected with T. mentagrophytes), and Microsporum canis group (infected with M. canis), and each group was classified into three subgroups, i.e., itraconazole group treated with oral itraconazole of 4 mg per kilogram body weight per day from day 0 to day 14 after infection, terbinafine group treated with oral terbinafine of 5 mg per kilogram body weight per day from day 0 to day 14 after infection, and untreated group receiving no therapy. The therapeutic effect was evaluated according to skin lesion score and fungal examination results on day 8, 11 and 14 after infection. Results Obvious lesions were observed and fungal examination was positive in untreated, infected pigs on day 8 after infection. In T. mentagrophytes-infecyted pigs, the skin lesion score on day 8, 11, 14 was 9, 1 and 0 in itraconazole group, 8, 5, and 1 in terbinafine group, 48, 52, 40 in untreated group, respectively, and there was significant difference between treated and untreated groups on the three time points (all P<0.01); the mycological cure rates on the above time points were 66.7%, 83.3%, 83.3%, in itraconazole-treated pigs, 83.3%, 83.3%, 83.3%, in terbinafine-treated pigs, 0, 0, 0 in untreated pigs, respectively, with no significant difference between itraconazole and terbinafine group (all P>0.05) but statistical difference between untreated and treated groups (all P<0.01) on all time points. Meanwhile, in M. canis-infected pigs, the skin lesion score on day 8, 11, 14 reached 3, 0, 0 in itraconazole group, 9, 2, 0 in terbinafine group, 46, 47, 39 in untreated group, respectively, and mycological cure rates 83.3%, 83.3%, 83.3% in itraconazole group, 83.3%, 83.3%, 83.3% in terbinafine group, 0, 0, 0 in untreated group, respectively; significant difference was noticed in the two parameters between the treated and untreated groups (all P<0.01) but not between the two treated groups (all P>0.05). Conclusion Itraconazol and terbinafine exhibit similar excellent antifungal activity in routine model of T. mentagrophytes-and M. canis-dermatophytosis.
