OBJECTIVE To learn about the factors affecting the quality of the air in operating-rooms and discuss the methods of improving their air quality.METHODS The dynamic and static air bacteriology between laminar air flow operating-room and normal operating-room of a fertiary care level hospital of grade Ⅰ in Changchun were observed.RESULTS The passing rate of samples for air static bacteriology between two types of operating rooms at the begining of selective operations(T0) was without difference.At the begining of emergency operations,there was a disparity.The total number of bacteria in normal operating-room increased with the operating-time,but in the laminar flow operating-room,the total number of bacteria increased in fluctuations during the(T2) time(60 ming since operation begain),and descended dramatically during the(T3) time(90 min since operation).CONCLUSIONS The emergency and operation-time are the main factors affecting the air quality in operating-room and the cleaning air-condition could improve the air quality.

Objective: To investigate the effects of ω-3 fish oil fat emulsion on nutritional status and humoral immunity in postoperative patients suffering from gastrointestinal malignancy. Methods: Thirty patients of gastrointestinal malignancy were randomly divided into study group (n = 15) and control group (n = 15). All the patients were assigned to receive total parenteral nutrition with the equal nitrogen and calory,and those in study group received fish oil fat emulsion additionally. Liver and renal function, blood lipid, haemoglobin, albumin, transferrin, total lymphocyte count (TLC) , B lymphocyte subsets (B1, B2), immunoglobin(IgG, IgM, IgA) and complement(C3, C4) were determined preoperatively and 1, 6d postoperatively. Results: There were no significant differences in liver and renal function and blood lipid on postoperative day 6 versus preoperation in all the two groups. TLC, IgG, IgM, C3 on postoperative day 6 were siginificantly higher in the study group(P < 0. 05). Haemoglobin, albumin, transferrin and B lymphocyte subsets were not significantly different between the two groups. Conclusion: Fish oil fat emulsion treatment was safe and tolerated, and could improve the humoral immunity in patients.

Objective To investigate the relationship between brucellosis arthritis of the hip and femoral head necrosis.Methods In August 2007 to August 2013,16 diagnosed and hospitalized patients with brucellosis complicated with femoral head necrosis in Heilongjiang Land Reclamation Bureau General Hospital were chosen as the objects of observation,and the patients' hospitalization information was analyzed retrospectively.Patients' medical records were investigated and analyzed.Observations included general condition of the patient,clinical symptoms and signs,imaging,pathology,treatment and curative effect.Results All the 16 patients had definite clinical manifestations of hip arthritis and femoral head necrosis including hip pain,limited mobility,positive 4 test,limp or bedridden,and sick limb muscle atrophy.Imaging examination:X-ray computer tomography (CT) showed cystic change and deformation collapse of femoral head.Magnetic resonance imaging(MRI) showed low signal on weighted T1 images,high signal on weighted T2 and soft tissue granulation hyperplasia could be seen in the hip joint.Pathological examination:most femoral bone tissue necrosis,dissolved,bone cells disappeared,a few bone cells present,and some fibrous tissue hyperplasia.Patients were treated with antibiotics according to the treatment principles of brucellosis,and the effect was obvious.Conclusions There is a causal relationship between brucellosis arthritis of the hip and femoral head necrosis.Therefore,positive and effective treatment of brucellosis arthritis of the hip in the early stages is crucial to prevent the occurrence of femoral head necrosis.

ObjectiveTo observe the effect of parathyroid hormone on expression of matrix GLA protein (MGP) in ovariectomized SD rats and primary osteoblast,and to study the role of MGP on the possible mechanism of postmenopausal osteoporosis.MethodsThirty-six Sprague-Dawley female rats were allocated into 3 groups,12 in each:sham operation group,ovariectomized group( OVX group),ovariectomized and parathyroid hormone treatment group.Animals in the parathyroid hormone group were injected parathyroid hormone (20 μg/kg,three times a week for 12 weeks) three weeks after ovariectomy.All rats were sacrificed after 18 weeks.Urine and serum were collected every three weeks.Lumbar vertebral bones were observed by immunohistochemistry.Bone mineral density (BMD) of lumbar vertebra of rats was determined.The content of MGP in serum and urine was determined by enzyme-linked immunosorbent assay (ELISA).Expression of undercarboxylated Matrix GLA Protein (ucMGP) was detected by immunochistochemistry.Relative quantification of MGP mRNA expression in lumbar vertebra bone was detected by Fluorescent real-time quantitative polymerause chain reaction.Results ( 1 ) 18 weeks after ovariectomy,BMD of lumbar vertebra in OVX group was lower than those in sham group and parathyroid hormone group significantly ( P＜0.05 ).(2) The content of MGP in serum and urine was dynamic variation after treatment hy parathyroid hormone,and it was significant compared with OVX group ( P＜0.05 ).( 3 ) Immunohistochemical localization of ucMGP was seen in lumbar vertebra in OVX group.(4) Relative quantification of MGP mRNA expression in lumbar vertebra in OVX group was increased significantly compared with other groups ( P＜0.01 ).( 5 ) parathyroid hormone ( 1-34 ) in 10-7mol/L,10-8mol/L,10-9 mol/L up-regulated MGP mRNA expression in primary osteoblasts about 6.78,5.31,and 2.23 times than control respectively.It was in a dose-dependent manner.ConclusionThe effect of parathyroid hormone on the expression of matrix gla protein may play an important role in mechanism of postmenopausal osteoporosis

Objective To explore the relationship between job stressors,montal health and intention to quit of pediatric nurses by comparing with nurses in internal medicine department. Methods Job stressors, mental health,intention to quit of pediatric nurses and their relationship were investigated among nurses in above mentioned wards from three third-level and first-class hospitals by using questionnaires. Results The scores of some factors of job stressors and nine factors of SCL- 90 of pediatric nurses were much higher than those of internal medicine nurses. There was a significantly positive correlation between some factors of job stressors, mental health and intention to quit of pediatric nurses. Conclusions Working pressure is a factor of low mental health level and intention to quit of pediatric nurses. Effective management strategies should be imple-mented to protect the mental health of pediatric nurses and decrease the loss of nurses.

Objective To build the indicators system for clinical pathway management as required by clinical pathway control.Methods An indicators system was proposed by means of evidence-based review,focus group discussions,and ratings of the indicators' importance by doctors and nurses.A multidisciplinary panel of 60 experts from across the country were selected.A 3-round Delphi survey was made on the proposed indicators.The weights of the indicators were established by analytical hierarchy process (AHP).The response rate,Cronbach's α,and the authority coefficient of experts were used as a measure of reliability.Results The response rates of the 3 rounds were 85％,70％,and 94％; the experts authority coefficient was 0.80.The ccoefficient of variation falls with the rising number of consultations.The Kendall's W ranged from 0.40 to 0.83.Following the 3 rounds,consensus was achieved among experts as such a system comprising three first-level,9 second-level,and 36 third-level indicators.Conclusion The expert consultation has achieved reliable results.The established indicators system can serve as a useful instrument for standardized development of clinical pathways management and constant improvement.
