Objective To observe the effect of the action research method in cultivating the scientific research ability of nurses.Methods 45 nurses were choosed as the research objects in our hospital from March to May in 2014 using the method of action research,and definiting the specific problems first,then through the training process of plan-action-observation-training,the study subjects were divided into three groups to participate in the three cycle of scientific research training by lottery.the training effect of scientific research ability in three cycles after training were evaluated.Results The scientific research level of nursing staff was in the medium level,and the total score was (42.33±15.10) points.After the three cycle,the total score of scientific research ability was increased to (79.73±10.77) points,and the difference was statistically significant (t=-13.199,P＜ 0.05).In the three cycle,the total score of scientific research ability respectively was (71.87±8.23) points,(8.39±88.87) points,(78.47±8.32)points,and the difference was statistically significant (F=15.940,P ＜ 0.05);the scores of the project plan respectively was (67.20±13.60)points,(70.13±14.31) points,(78.73±8.69) points,and the difference was statistically significant (F=3.474,P ＜ 0.05).Conclusions Using the action research method can effectively improve the ability of scientific research of nurses.

Objective To study signs of ultrasonography in multiple renal arteritis (MRA) by color Doppler flow imaging(CDFI) and X-ray angiography.Methods 2-D ultrasonography and color Doppler were performed on 23 cases of MRA with 39 diseased blood vessels.The morphology and diameters of stenonsed renal arteries of the kidneys were observed respectively by 2-D ultrasonography and CDFI.CDFI was adopted to observe maximum of velocity(Vmax),minimum of velocity(Vmin),resistance index(RI),acclerate(ACC) and acclerated time(TA) of the renal arteries,and the values were compared with those by X-ray angiography and with those of the normal controls.Results MRA's renal volume and diameter were significantly different from those of controls ( P

Objective To discuss the mechanism of traditional Chinese medicine apozem which was pressurized by automation to treat acne.Method Bacteriostasis effect of traditional Chinese medicine and western medicine on propionibacterium acnes and rate of seborrhea(SER) pre-and post-treatment were observed.Result Traditional Chinese medicine apozem had more obviously bacteriostatic action than western antibiotic medicine(erycin,amphemycin,chlorodeoxylincomycin)(? 2 =71.77,P

This article reviewed the literatures about degeneration at the segments adjacent to the fusional and instrumental segments. The hypertrophic degenerative arthritis of the facet joints, intervertebral instability and spinal stenosis were the common pathologic changes. The changes usually occurred at the upper segment of spinal fusion. The average time period for the development of adjacent segment degeneration might be shortened after spinal fusion with instrumentation. The main reason was stress and hypermobility increased at the adjacent segment and postoperative malalignment of the spine after spinal fusion.

Objective To study the effect and mechanism of the Fosinopril combined with Fenofibrate on the prevent?ing of diabetic retinopathy. Methods A total of 150 viripotent ICR mice(100 male mice, 50 female mice) were randomly di?vided into five groups(n=30), including A group (Sham group), B group (Model group), C group [Fosinopril prevented group, 20 mg/(kg·d)], D group [Fenofibrate prevented group, 400 mg/(kg·d)] and E group (Fosinopril combined with Fenofibrate pre?vented group). The expression levels of Bax and Bcl-2 gene mRNA were determined by RT-PCR method. TUNEL staining method was used to detect the apoptosisi of retinal cells. Results The Bcl-2 mRNA of A group, Bax mRNA of B group were higher than those of other four groups. Bcl-2 mRNA of E group was higher than that of C group and D group, while the Bax mRNA was lower than those of two groups(all P<0.05). The TUNEL index of B group was the highest than other groups, which of E group

Atlas fracture is a rare lesion occurred in cervical vertebrae.This review summarize the new approach about the classification,etiological factors,clinical manifestations,diagnosis methods and treatments of the disease.

Cryopreservation of bone and osteochondryl allografts plays significant role in revision surgery of large bone defects and osteoarticular reconstructive surgery.As a transplantable tissue,bone has the distinct advantage of long-term storage with seemingly little adverse effect.The author reviewed the history and present state of bone bank in the world as well as in our country,and discussed the general principles and methods of donor selection,bone procurement,storage,sterilization,management and the costs associated with this facility.

BACKGROUND:Establishing the animal model of membranous nephropathy is of importance to figure out the pathogenesis of membranous nephropathy.
OBJECTIVE:To investigate the expression of nephrin and podocin in the model of membrane nephropathy in rats, and to investigate their relationships with the pathogenesis of membranous nephropathy.
METHODS:A total of 40 Sprague-Dawley rats were equivalently randomized into model and control groups. Rats in the model group were in premunity by given subcutaneous and multi-point injection of 1 mg cationic bovine serum albumin firstly dissolved in 0.5 mL normal saline and then ful y emulsified with the equal incomplete Freund’s adjuvant for 1 week, and 16 mg/kg cationic bovine serum albumin was injected via vein tails, once every other day for 4 weeks. The same volume of normal saline was injected into the controls. The mRNA expressions of nephrin and podocin in renal tissues were detected using real-time PCR, and biochemical indicators and morphological observation were measured at 2 and 4 weeks after modeling.
RESULTS AND CONCLUSION:(1) In the model group, the total amount of urine and serum albumin levels were significantly decreased accompanying with overt proteinuria, and the serum creatinine, urea nitrogen, cholesterol and triglyceride levels were significantly increased al in a time-independent manner compared with the control group (P<0.01), and the difference was significant (P<0.05). (2) The pathological examination showed that rats in the model group had different degrees of renal tubular dilatation, glomerular basement membrane thickening, mesangial cel s and stromal hyperplasia, which was typical of membranous nephritis. (3) Moreover, the mRNA expressions of podocin and nephrin in the model group were lower than those in the control group. (4) In conclusion, the decreased expressions of podocin and nephfin may disturb the integrity of the slit membrane of podocytes giving rise to the damage of glomerular filtration barrier, and proteinuria appears in final.

Objective To investigate the fatigue experience of the community-dwelling frail elderly to establish the conceptual model.Methods Grounded theory was adopted.With MAXQDA v10.4.15.1for 3 levels coding,the conceptual model of fatigue experience of community-dwelling frail elderly people was structured through constant comparison and in-depth analysis.Results Multi-response,selfmanagement,safe and belonging,hitting rock bottom,accepting and transferring formed the conceptual model.Conclusions Based on the conceptual model,nurses should pay more attention to concern about the fatigue experience of community-dwelling frail elderly people,and probe different assessment methods to enrich comprehensive geriatric assessment (CGA),then improve the community health service level and the quality of elderly people's life.

Prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), plasma fibrino-gen (FIB), platelet aggregation rate and blood clots-fibrinolytic dynamic figure were taken as indexes in the evalua-tion of anticoagulant activity in vivo of active component F2-2 from Eupolyphaga seu Steleophaga. After 5 days of hypodermic injection of adrenaline, the rat model of acute blood stasis was established. Indexes were determined af-ter the model rats were treated with an intragastric administration of F2-2 for 9 days. The results showed that com-pared with the model group, PT/APTT was prolonged, FIB content was decreased, platelet aggregation rate and the largest of blood coagulation were declined after 9 days of intragastric administration in the model group. However, there was no difference on TT. It was concluded that the anticoagulant component F2-2 separated from E. seu Steleophaga showed favorable anticoagulant activity in vivo. However, its mechanism remained unknown and request-ed further researches.
