Objective To explore and classify the subjective opinions of nurses on whistle- blowing, and identify the subjective characteristics of each type. Methods This study applied Q -methodology, protocols which could determinate subjective opinions of nurses on histle-blowing were set up and underwent interview investigation, data of the interviews went through Q-factor analysis. Results Most nurses had a positive attitude toward whistle - blowing because it could prevent any nursing activity not based on expertise and professional ethics from causing disadvantages for patients. At the same time, however, they requested the creation of a legal framework in which whistle-blowing was done in a way to increase trust among colleagues. Meanwhile, some nurses showed resistance to whistle - blowing. Conclusions Whether whistle - blowing can reach its aims depends on nurses' attitude toward it. Most Korean nurses support whistle-blowing. Nursing activity not based on expertise and professional ethics and causing disadvantages for patients can be avoided if a legal framework is established for whistle-blowing.

Clinical studies show that the factors that impact the quality of life (QOL) in patients with lung cancer are comprehensive.Physiological factors include breathing difficulties,cancer-related fatigue.Depression,anxiety and other psychological factors also play a major role.Social and family support is also crucial to improve the QOL in patients with lung cancer.

Objective To characterize clinical features,antimicrobial susceptibility and the outcome of nosocomial Acinetobacter baumannii meningitis.Methods All patients with nosocomial meningitis due to Acinetobacter baumannii in 2nd Affiliated Hospital Medical School of Zhejiang University between January 2010 and October 2011 were retrospectively reviewed.Results During the study period,40 patients of this nosocomial infection were identified,who came from neurosurgery ward (19 cases,47.5％),neurosurgieal intensive care unit (18 cases,45.0％),emergency intensive care unit (2 cases,5.0％) or intensive care unit (1 case,2.5％).All the patients had a history of recent neurosurgical procedures. Fever and disturbance of consciousness were the major manifestations,and cerebrospinal fluid examination showed elevated white blood ceil count and protein,and reduced glucose.All isolated pathogens were resistant to the first line antibiotics.The fatality rate was high. Conclusions The most common risk factor for nosocomial Acinetobacter baumannii meningitis is neurosurgery. Resistance to the first line antibiotics is common among all pathogens isolated.The prognosis of the meningitis is poor.

Objective: Our purpose was to study the concentration of soluble tumor necrosis factor receptor-Ⅰ(sTNFR-Ⅰ) in the serum of patients with acute tuberculosis. Methods: The levels of soluble TNFR-Ⅰ in serum were measured in 11 patients with acute tuberculosis. Concentration of sTNFR-Ⅰ were measured by using enzyme-linked immunological binding assay. Results: In patients with acute tuberculosis, especially severe tuberculosis, serum levels of sTNFR-Ⅰ increased significantly (P<0.01), compared with those of control. After antituberculosis therapy, serum levels of sTNFR-Ⅰin patients with acute tuberculosis decreased by various degrees. Conclusion: Measurements of sTNFR-Ⅰ in serum of patients with acute tuberculosis could be an important index in the judgement of the outcome of the disease.

Macrophage migration-inhibitory factor (MIF) is a cytokine which can promote tumorigenesis.MIF can promote tumorigenesis by directly inducing oncogene transformation,stimulating cell division,as well as indirectly inhibiting tumor apoptosis,promoting its invasiveness and angiogenesis.MIF-targeted biological therapy may become a new therapeutic strategy for malignant tumor.

BACKGROUND:Methylene blue can hinder abnormal pain conduction via the sensory nerve, and its mechanism is to block bradykinin-induced hyperalgesia and eliminate pain caused by local tissue inflammation.
OBJECTIVE:To observe the influence of methylene blue solution on the lumbar spinal cord and spinal ganglia function of rats, and to investigate whether methylene blue is safe for treating discogenic low back pain.
METHODTotal y 120 Wistar rats were randomly divided into five groupthree experimental groups, a saline control group and a blank control group, n=24 in each group. Lumbar segmental dura was exposed in rats. In the three experimental groups, 0.2, 1, and 2 mL methylene blue were injected epidural y, respectively. The saline control group was subjected to the epidural injection of 1 mL saline. In the blank control group, there was no treatment. Six rats from each group were selected randomly and perfused at 30 minutes, 2 hours, 24 hours, 72 hours after injection, respectively. Then, the corresponding segments of the spinal cord and ganglions were removed. Hematoxylin eosin staining was used for comparing histological and structural changes under light microscope.
RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that at 30 minutes, 2 hours, 24 hours and 72 hours after injection of methylene blue, the spinal dorsal side exhibited the structural integrity, clear boundaries between the white matter and gray matter, dense nerve fibers in the white matter, and round or oval nuclei of glial cells among fibers;dense nerve fibers in the posterior horn of gray matter;light-colored neuronal nuclei with prominent nucleoli;a bundle of nerve fibers among cellpopulations. There was no significant change in tissue structure of lumbar spinal cord and spinal ganglia between the experimental groups and the saline control group or between the experimental groups and the blank control group. Thus, the epidural injection of 1%methylene blue has no significant effect on the spinal cord and spinal nerve structures.

Objective To explore the risk factors for hospital acquired pneumonia (HAP) in patients with neural-intensive care unit (NICU).Methods The clinical data were analyzed retrospectively for 207 patients in NICU ≥ 5 d,to determine possible risk factors with HAP.Results The incidence of HAP was 14.01％(29/207).Correlation analysis showed that old age,disturbance of consciousness,dysphagia,vomiting,low pre albumin,NICU residence time ≥ 30 d,indwelling nasogastric tube,the use of the acid-blocking drugs,tracheal intubation,tracheal incision,mechanical ventilation and deep bronchoscopic suctioning were the related factors of HAP (P ＜ 0.05 or ＜ 0.01),but blood glucose,sedative drugs were unrelated with HAP (P ＞ 0.05).Conclusion There is a high incidence of NICU in patients with HAP,taking comprehensive measures actively,reduce risk factors,can effectively control the occurrence of HAP in NICU.

BACKGROUND:Class II malocclusion is commonly observed in clinics, with the main manifestation of skeletal malocclusion, and mandibular retrusion is the main reason. Class II malocclusion should be treated early to correct skeletal malformation and improve facial appearance. OBJECTIVE:To compare the biomechanics change in early treatment of Class II division 1 malocclusion with Twin-Block appliance and straight wire appliance combined with face-bow and Class II drawing. METHODS: Thirty patients with malocclusion who were at peak velocity on the growth curve were randomly divided into two groups, with 15 cases in each group. Patients in each group were treated with Twin-Block appliance and straight wire appliance combined face-bow and Class II drawing, respectively. The cephalometric records of al patients were examined before and after the treatments. The acquired data were processed by statistical analysis. RESULTS AND CONCLUSION:After treatment, al molars and cuspid teeth achieved or reached Class I, and ANB angle decreased to normal range. The bone effect of Twin-Block appliance was more significant than straight wire appliance. Using Twin-Block appliance, the length of mandible body and lower face height increased significantly. Experimental findings indicate that, Twin-Block appliance has significant therapeutic effects in treatment of early skeletal Class II division 1 malocclusion patients, who are at peak velocity on the growth curve. With the biomechanical effects, this treatment corrects asymmetrical jaw relation, reconstructs the tissue, and obtains satisfactory lateral facial profile of soft tissues. The therapeutic effect is more obvious for patients with obvious mandibular retrusion, flared upper incisors and upright lower incisors.
