Hospital culture plays a more and more important role,among various factors that influence employee satisfaction.Study on hospital culture is gradually growing out of a pure conceptual research and emerging into an area of correlation analysis. Our studies on the hospital culture developments and employee satisfaction in a tertiary hospital,analyzed the correlations between hospital culture and employee satisfaction and its impact,with recommendations for reform strategies.

Objective To compare the quadriceps strength and short-term outcome in patients who had undergone primary total knee arthroplasty (TKA) with minimally invasive (MIS) or conventional surgical technique.Methods Sixty-eight knees undergoing TKA were evaluated and they were randomly divided into two groups.One group included 34 knees which were undergone conventional approach,and the other group included 34 knees undergone MIS approach.The age,BMI,quadriceps strength,extension lag,American Knee Society Score (KSS),Western Ontario and McMaster Universities (WOMAC) osteoarthritis index and visual analogue scale (VAS) of pain of all patients were evaluated at the day before surgery and the 1st,2nd,3rd,6th,and 12th months after surgery.Results At the 1st,2nd,3rd,6th,and 12th months after surgery,the quadriceps strength in MIS group was 0.59±0.12,0.74±0.18,0.86±0.16,1.02±0.17,1.05±0.04 N·m/kg respectively,while in conventional group was 0.46± 0.56,0.56±0.12,0.70±0.16,0.94±0.19,1.04±0.03 N· m/kg respectively.The extension lag in MIS group was 13.11°±6.56°,8.53°± 5.12°,4.79°±3.62°,1.53°±2.64°,1.62°±1.76° respectively,while in conventional group was 22.47°±8.41°,16.23°±6.26°,10.58°± 4.4°,2.58°±2.85°,1.62°±1.76° respectively.There were significantly differences in the two groups.Meanwhile,compared with conventional patients,MIS patients demonstrated significantly higher KSS scores at the 1st and 2nd months postoperatively.WOMAC scores were significantly lower in MIS group than in conventional group at the 1st month after surgery.During the first postoperative week,MIS technique significantly decreased VAS scores,showing significance.On the other hand,no significant difference was observed with respect to deep infection incidence and radiological outcome between two groups.Conclusion MIS TKA offers a significant improvement in extensor muscle strength over conventional surgery.These results suggest that the MIS approach results in better outcomes with regard to maintaining extensor strength than the conventional surgical approach.

Lipoproteins are biological lipids carriers. The natural and reconstituted lipoprotein based drug delivery systems have been extensively developed in recent years. This article reviews the development of natural and reconstituted low-density lipoprotein and high-density lipoprotein based vehicles in the antitumor area.

Background Research demonstrated that alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid GluR2 (AMPA-GluR2) is associated with amblyopia.It has been shown that levodopa and cytidine diphosphate choline can improve visual function of amblyopic children,but the mechanism is unclear.Objective This study was to explore the possible effects of levodopa and cytidine diphosphate choline on amblyopia.Methods Monocular deprivation (MD) animal models were created in 60 2-week-old SD rats by monolateral eyelid suturing and observed for 31 days and reared in natural light together with 15 other matched normal healthy SD rats.The models were randomly divided into the MD group,levodopa group,cytidine diphosphate choline group and normal saline control group,with 15 rats for each group.40 mg/kg of levodopa,80 mg/kg of cytidine diphosphate choline,I ml normal saline were given to the rats,respectively,for 28 consecutive days.Expressions of the AMPA-CluR2 protein and AMPA-CluR2 mRNA in the rat visual cortex were detected by immunohistochemistry,Western blot and real-time fluorescence quantitative PCR.Use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The expression values of the AMPA-GluR2 protein (AMPA-GluR2/β-actin) and AMPA-GluR2 mRNA (2-△△Ct) were significantly lower in the MD group than those of the normal control group (protein:0.32 ± 0.02 vs.0.64 ± 0.05,t =13.287,P＜0.05 ;mRNA:0.30±0.01 vs.0.84±0.03,t=38.184,P＜0.05).Those in the levodopa group were significantly increased in comparison with the normal saline solution group (protein:0.59 ±0.04 vs.0.33 ±0.03,t =11.628,P＜0.05 ; mRNA:0.71±0.06 vs.0.33 ±0.02,t =13.435,P＜0.05).The expression values of the AMPA-GluR2 protein and AMPA-GluR2 mRNA were significantly increased in the cytidine diphosphate choline group compared with the normal saline solution group (protein:0.52 ± 0.04 vs.0.33 ± 0.03,t =8.497,P ＜ 0.05 ; mRNA:0.48± 0.04 vs.0.33 ± 0.02,t =7.500,P＜0.05).Conclusions AMPA-GluR2 is associated with the plasticity of visual development.Levodopa and cytidine diphosphate choline may improve visual function by down-regulating the expression of AMPA-GluR2 in the visual cortex.

Background The afferent signals of proprioceptor in extraocular muscles play an important role in controlling eye position and conjugate movement. Palisade ending in the extraocular muscles is the main source of proprioceptive information, and its abnormalities in structure and function may be associated with the occurrence of nystagmus. Objective This study was to observe the changes of palisade ending in the extraocular muscles of patients with congenital nystagmus ( CN) and discuss the probable mechanism. Methods Modified Kestenbaum procedure was performed on 10 patients with CN, and the extraocular muscle samples were collected during the operation. Normal extraocular muscle samples were obtained from the enucleated eyeballs after ocular wound. The ultrathin sections of extraocular muscles were prepared and double-staining by uranyl acetate and lead citrate. The morphological changes of the palisade ending of extraocular muscles were examined under the transmission electron microscopy. Written informed consent was obtained from each subject before surgery. Results The ultrastructure of palisade ending in the extraocular muscle of CN subjects showed the different degrees of alterations. The mild changes included the collapse and disconnection of external capsules and the nonhomogeneous electron-dense substracts. The degeneration and dissociation of myelin in nerve endings, swelling and vacuolation of mitochondria were also exhibited. Myeloid body was found in axon. In the severe patients,the necrosis of Schwann' s cells,dissolve of axon and disappear of capsules were seen. Conclusion The palisade ending of extraocular muscle in the patients with CN are obviously abnormal in comparison with normal one. These alterations are probably associated with the etiology and pathogenesis of CN.

Objective To investigate the clinicalmanifestation,monitoring and therapeutic measure of severe enterovirus 71 ( EV71 ) infection in children.MethodsForty-five cases of severe EV71 infectionwere admitted in our PICU from May 2010 to Sep 2011.The vital sign and arterial blood pressure,central venous pressure,mixed venous oxygen saturation,dynamic non-invasive heart function and urine volume were monitored.Forty-five cases were divided into 3 stages according to clinical manifestation:( 1 ) nervous system involvement stage; (2) respiratory system involvement stage; ( 3 ) circulatory system involvement stage ( compensation and decompensation).We adopted individualized remedy measure according to different stages.ResultsIn 45 cases,38 cases discharged from hospital,the cure rate was 84.4％.Among all the 38 cases,nervous system involvement was found in 19 cases,respiratory system involvement was found in 12 cases,circulatory system involvement was found in 7 cases.Seven cases died,who had circulation failure.ConclusionWe should identify severe EV71 infection early.Positive control of high fever,appropriate liquid treatment,control of high blood pressure,early respiratory support,preventment of circulation failure are the key measures for treatment.Individualized monitoring and treatment are effective in children with severe EV71 infection.
