Objective By taking emergency treatment of craniocerebral trauma for example, we studied the competence characteristic composition for emergency treatment of eraniocerebral trauma aiming at doctors and nurses, besides,their competence characteristics were compared as well. Methods By comprehensive application of qualitative and quantitative methods, the competence characteristic eomposi-tions of doctors and nurses were obtained, the corresponding competence characteristic scale was estab-lished, and underwent subsequent application for its validity and reliability. Results After many times of factor analysis and factor rotation, competence characteristic compositions and scale for doctors and nurses engaged in emergency treatment of eraniocerebral trauma were obtained, accumulative contribution of com- mon factors was 69.33% and 69.99%,ot coefficient was 0.826 and 0.930, split-half reliability was 0.771 and 0.791 ,α coefficient of internal consistency of every subseale ranged from 0.574 to 0.898, which showed good validity and reliability. Conclusions Doctors and nurses engaged in emergency treatment of cranio-cerebral trauma possess different competence characteristic compositions from general medical workers,their competence characteristics are both overlapping and different.

OBJECTIVE:To investigate Smad3 and Smad7 expression in cardiac tissues in myocardial infarction (MI) rats and the effect of simvastatin (SIM) on expression of Smads.METHODS:36 rats were randomized into SIM (40 mg?kg-1,n=12) group,MI group (normal saline,n=12) and SHAM group (normal saline,n=12).Rats in first two groups were induced MI model.Rats of 3 groups were sacrificed after four weeks administration.The mRNA expressions of Smad3 and Smad7 in non-infarction regions were measured by RT-PCR.Smad3 and Smad7 protein expressions were measured by Western blotting assay.RESULTS:As compared with SHAM group,the expressions of Smad3 in MI group and SIM group were increased while the expressions of Smad7 were decreased.As compared with MI group,the mRNA expression and protein expression of Smad3 in SIM group was decreased while that of Smad7 increased (P

Objective To explore the expression of origin recognition complex1(ORC1) during DNA replication progress of rat vascular muscle cells(VSMCs).Methods VSMCs of rat thoracic aorta were obtained by the adherence method of tissue culture.The growth curve was drawn by MTT.The association between DNA replication and the expression of ORC1 mRNA and protein in different growth phases of VSMCs was analyzed.Results The expression of ORC1 mRNA and protein in quiescence stage of VSMCs was not found.After stimulated with serum,the expression of ORC1 mRNA in rat VSMCs increased significantly,peaked at 12-24 h.The expression of ORC1 protein was similar to ORC1 mRNA in VSMCs.Meanwhile,the higher DNA replication of stimulated VSMCs was observed,peaked at 12-24 h after serum addition. Conclusion ORC1 may be involved in the DNA replication of rat VSMCs during the progress of proliferation.

Objective To investigate the influence of RNA interference targeting ORC1 gene on the proliferation of rat vascular smooth muscle cells(VSMCss).Methods VSMCss were transfected with siRNA targeting ORC1 gene by liposome.The expression of ORC1 protein was detected by Western blotting.MTT test and ~(3)H thymidine~()(~(3)H-TdR) incorporation were used to detect VSMCss proliferation.The expression of proliferating cell nuclear antigen(PCNA) in VSMCss was detected by immunocytochemistry.Results After transfected of the three pairs of siRNA targeting ORC1 genes respectively,the expression of ORC1 was all lower than that in the control group(non-transfection and negative siRNA).Especially,that in the group transfected of the second pair positive siRNA decreased most significantly.The optical density of MTT,~(3)H thymidine incorporation and the expression of PCNA decreased significantly in VSMCss transfected with siRNA targeting ORC1 gene as compared with that in the control group.Conclusion ORC1 gene silenced by RNA interference can inhibit VSMCss proliferation.

Objective To explore origin recognition complex 1(ORC1) expression in the rat vascular muscle cells at different phases of proliferation.Methods Vascular smooth muscle cells(VSMCs) of thoracic aorta of rats in primary culture were obtained by the adherence method of tissue culture.Total RNA of VSMCs was extracted.The expression of ORC1 mRNA of VSMCs at different phases of proliferation was determined by reverse transcription polymerase chain reaction(RT-PCR) and the expression of ORC1 protein by immunocytochemistry and laser confocal microscopy.Results Cultured VSMCs were confirmed by light microscope and immunocytochemistry.The expression of ORC1 mRNA in the quiescence stage of VSMCs was not found.After VSMCs were stimulated with serum,the level of ORC1mRNA had an obvious increase at 6 h,peaked at 12 to 24 h and decreased in the following 24 h.The expression of ORC1 protein was also not found in the quiescence stage of VSMCs,but the level of ORC1 protein during proliferation of VSMCs was significantly increased.Conclusion ORC1 may have an important role during the process of VSMCs proliferation in rats.

Objective To investigate the clinical characteristics,pathogen distribution and outcome of lower respiratory tract fungal infection in patients with mechanical ventilation in emergency intensive care unit(EICU). Methods The clinical data of patients with lower respiratory tract fungal infection treated with mechanical ventilation in EICU were retrospectively analysed. Results Eighty(64.5%) of the 124 patients with mechanical ventilation experienced lower respiratory tract infection,among whom 21(26.2%) were complicated with fungal infection.The predominant pathogen was Candida(Candida albicans,n=11;Candida tropicalis,n=5;Candida smooth,n=3;Candida parapsilosis,n=2).Compared with patients with non-fungal infection(n=59),those with fungal infection(n=21) had higher APACHE II score,longer mechanical ventilation time and longer ICU stay duration(P

To assess the efficiency and reliability safety of ganciclovir to herpes simplex virus keratitis.
●METHODS: All of the randomized controlled trials for the study of ganciclovir versus acyclovir in the treatment of herpes simplex virus keratitis were collected from Cochrane Library, EMbase, PubMed, Chinese Bio -medicine Database, China Journal Full-text Database, VlP Database and WanFang Database. Then the data were extracted and evaluated by two reviewers independently. Risk of bias assessment was evaluated by a tool recommended by Cochrane Library. Revman 5. 0 software was used for statistical analysis.
●RESULTS: Finally, 14 randomized controlled trials were included, 4820 patients totally. Subgroups were used according to the number of patients and diseased eyes as well as the difference of follow-up time. For and relapse rate, ganciclovir group was overmatch acyclovir group. There were statistical differences between the two groups [RR= 1. 22, 95%CI (1. 10-1. 36); OR = 4. 50, 95% CI (2. 02-10. 04); RR = 0. 23, 95% CI (0. 10-0. 52)]. Compared with acyclovir, ganciclovir had less side - effect. There were statistical differences between the two groups [RR = 0. 12, 95%CI (0. 03 - 0. 46)]. All of the side effects of the two groups can be relieved by themselves.
● CONCLUSlON: Current evidence suggests that the ganciclovir is more efficient and safe than acyclovir in the treatment of herpes simplex virus keratitis.

Objective To compare the inhibition effect of budesonide suspension and dexamethasone on the rats′ pneumonic anaphylacticitis and serum IL-5,and study the effect mechanism in treatment of asthma with glucocorticoids on systemic administration and with budesonide suspension.Methods Twenty-six health wistar rats were randomly divided into normal group,asthmatic group,budesonide suspension group and dexamethasone group.Asthma models were sensitized with egg albumin.Before sensitized,budesonide suspension group were administered inhalation of budesonide suspension,and dexamethasone group were administered abdominal injection of dexamethasone.The level of IL-5 was measured with enzyme linked immunosorbent assay(ELISA) reagent box,lung was eviscera-(ted after collecting) blood,pathological slice was made.Results The rats′ pathological changes of lung and bronchus were significant between asthma group and other groups,while there were no significant difference between budesonide suspension group and dexamethasone group,but both of two groups showed slight difference with normal group.Compared with normal group,the level of serum IL-5 in asthma group raised obviously,and there was significant difference(P0.05).Conclusions The treatment of inhalation of budesonide suspension can inhibit rats′ pneumonic anaphylacticitis,ameliorate rat anaphylactic asthma symptom.
