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 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 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

Objective To study the effectiveness of valsartan on the insulin resistance and high-sensitivity C-reactive protein(hs-CRP) of patients with essential hypertension.Methods One hundred and thirty patients with essential hypertension were randomly divided into two groups,the control group (n =65 cases) and the treatment group (n =65 cases).The patients in the control group were treated through amlodipine,while the patients in the treatment group were treated valsartan.They were all treated for six months.The insulin resistance(IR) and hs-CRP were compared.Results The systolic blood pressure and diastolic blood pressure were decreased after treatment in both groups (t =6.3706,6.4418,7.0519,7.2577,all P ＜ 0.01).There wasn't a significant difference between two groups (P ＞0.05).The IR and hs-CRP were decreased in both groups (t =6.3478,1.9977,4.0581,12.0722,all P ＜ 0.01).There was a significant difference between two groups (t =7.6049,4.6893,all P ＜ 0.05).Conclusion Valsartan can improve the insulin resistance and hs-CRP,which weren't dependent on lowing blood pressure.

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.

Objective: To investigate the inhibitory effect of survivin antisense oligonucleotide (ASODN) on the expression of survivin gene and proliferation of human hepatocellular carcinoma cell line SMMC-7721. Methods: The 20 mer antisense oligonucleotide (ASODN) targeted to the promoter region of survivin mRNA was designed and synthesized. The expression of survivin gene in hepatocellular carcinoma cell line SMMC-7721 was blocked by means of ASODN transfection mediated by DOTAP liposomal reagent. The changes of survivin protein and mRNA expression after transfection were as-sessd by Western blot and in situ hybridization, respectively. The apoptotic rate was detected by flow cytometer. The changes of cell adherent rate, cell growth activity, and the inhibitory rate of cell growth were also studied. Results: The expression of survivin protein and mRNA were decreased markedly after survivin ASODN transfection. Meanwhile, the cell adherent rate also decreased markedly while the apoptotic rate increased markedly. Conclusions: Transfection of ASODN targeted to the promotor region of survivin mRNA by DOTAP liposomal transfection reagent could down-regulated the expression of survivin protein and mRNA significantly in 7721 cell line and inhibit the proliferation of cancer cells. Survivin could be an important target in the therapy of hepatocellular carcinoma.
