To measure carotid intima media thickness(IMT) and to investigate the relationship between carotid atherosclerosis and some major risk factors in elder uremic patients, a cross sectional study was carried out in 30unselected elder uremic patients (16on hemodialysis). Fasting blood sampling for serum lipids, BUN, creatinine, hemoglobin, and echo colour Doppler evaluation of common carotid arteries and heart were performed , BP was measured in all patients (before dialysis day in hemodialysis patients). Relationship between the results and miltifactoral regression analysis were also carried out. 17 patients(56 6%)had carotid IMTwhile 12 dialysis patients(75%) had it. 6patients (20%) had at least one plaque. A significant correlation was found in internal diameter of carotid arteries, IMT and blood vessel resistance between left and right carotid arteries. Carotid IMT had a close relationship with serum BUN, creatinine, cholesterol, systolic BP and heart ejection fraction. In multiple regression models, serum creatinine and cholesterol was significant and an independent predictor of the degree of carotid IMT. In elder uremic patients, carotid IMT is quite common. Elder age, hypertension, degree of renal insufficiency and dyslipidemia are associated with carotid atherosclerosis. Serum creatinine and cholesterol appears to serve as an independent predictor of carotid atherosclerosis, which contributes to the cardiovascular complications and high mortality in elder uremic patients.

Objective To explore the roles of curcumin in regulating high level O6-methylguanine-DNA methyltransferase (MGMT) expression and the chemosensitivity of gliomas cells to temozolomide (TMZ) in malignant gliomas.Methods The expressions of MGMT were detected in C6 and U87 cell lines and primary malignant gliomas cell by qRT-PCR.The cell proliferation was analyzed after added in signal curcumin,signal TMZ,curcumin combined with TMZ in cells by CCK-8 assay.The cell apoptosis rate was detected by flow cytometry.Results Compared with single curcumin (C6:0.64 ±0.03;U87:0.63 ±0.06;primary cell:0.51 ±0.07) and single TMZ (C6:0.53 ±0.06;U87:0.51 ±0.04;primary cell:0.79 ±0.03),curcumin combined with TMZ (C6:0.14 ±0.01;U87:0.12 ±0.03;primary cell:0.29 ±0.02) could significantly reduce the expression of MGMT in C6,U87 cell lines and primary cell line (C6:F=23.675,P=0.006;U87:F=29.021,P=0.001;primary cell:F=25.534,P=0.001).The combination of curcumin and TMZ could significantly inhibit the cells proliferation,decrease the halfinhibition concentration (IC5o) value (C6:F=6.731,P=0.012;U87:F=17.321,P=0.008;primary cell:F=18.857,P =0.007).The apoptosis rate of the cells was significantly increased after the combined action of curcumin and TMZ (C5:F=25.871,P=0.001;U87:F=6.847,P=0.009;primary cell:F=36.641,P=0.000).Conclusion Synergistic effect of curcumin and TMZ can reduce the expression of MGMT and increase the chemosensitivity of TMZ to malignant glioma,and provide new strategy and methods for the treatment of malignant glioma.

Objective To evaluate the expression of the GLUT-1 glucose transporter in borderline and malignant epithelial neoplasms of the ovary. Methods Histologic sections of tumor tissues from 100 epithelial neoplasms of the ovary were stained for GLUT-1 using polyclonal GLUT-1 antibody and the labeled streptavidin procedure. Chi-square analysis was used to assess if their expression was associated with clinicopathoiogic characteristics of the tumors. Results Normal ovarian surface epithelial cell were either negative or weakly positive. The intensity of the stain was significantly stronger in malignant than borderline tumors (P<0.001). In malignant neoplasms, the intensity of the stain for GLUT-1 increased with histology. Conclusion Overexpression of the GLUT-1 transporter is associated with the histology and grade of the minors. These data suggest that the expression of this transporter may be closely related to the malignant transformation of epithelial ovarian tumors.

Objective To compare the effects of adjustable pressure drainage device, negative pressure ball drainage and drainage bag drainage on patients with the total hip arthroplasty. Methods The silicone drainage ball with negative pressure, the urine collection bag, the infusion set′s regulator were used to make adjustable pressure drainage device. 120 cases of total hip arthroplasties from January to December in 2015 were chosed and divided randomly into 3 groups based on the sequence of operation notifications. In 40 cases, drainage bag were used (control group 1), 40 cases with negative pressure ball drainage (control group 2) and 40 cases with adjustable pressure drainage device (experimental group). Total postoperative bleeding, the blood transfusion amount, swelling (the thickness of hematoma) and the nursing workload of the three groups were compared. Results The total postoperative bleeding, the blood transfusion amount, the thickness of hematoma and the nursing workload in the experimental group were (775.1±130.5) ml, (3.5±1.3) mm, (180.2±29.9) ml, (34.5±5.2) min. The total postoperative bleeding, the blood transfusion amount, the thickness of hematoma and the nursing workload in the control group 1 were (889.4 ± 160.8) ml, (5.2 ± 1.1) mm, (285.9 ± 30.4) ml, (40.6 ± 7.4) min and in the control group 2 were (876.2±156.7) ml, (4.3±1.2) mm,(208.3±33.3) ml, (50.3±8.5) min. Compared the data of the experimental group and the control group 1, the difference was of statistically significance (t=3.49-15.68, P < 0.01). Compared the data of the experimental group and the control group 2, the difference was of statistically significance (t=2.86-10.03, P<0.01). Conclusions The effects of adjustable pressure drainage device are better than the drainage bag and negative pressure drainage ball. It can effectively reduce the postoperative bleeding and the swelling degree, and bring a lot of relief to the patients and lots of convenience to the nursing work. The method is affordable, reliable and safe which should be promoted in the primary hospital.

Objective To explore the application of transitional care based on the Omaha system in postoperative rehabilitation of patients with breast cancer.Methods Seventy-two patients after radical mastectomy were assigned into two groups according to admission time,patients from June to December 2011 were set as the control group,patients from February to December 2012 were assigned to the intervention group,each group contained 36 patients.The patients in the control group received routine nursing,while patients in the intervention group were implemented transitional care program with Omaha system as framework from before discharge to 6-week follow-up after discharge from hospital.Nursing effect was compared between two groups from three aspects such as cognition,behavior and status.Results Twenty-three problems were found in the 6-week follow-up for the intervention group,including environmental domain,psychosocial domain,physiological domain and health-related behavior domain.Knowledge,behavior and status scores of the intervention group 6 weeks after discharge were significantly higher than those of the control group [(3.92 ± 0.48) scores vs.(2.41 ± 0.17) scores,(4.11 ± 0.49) scores vs.(2.83 ± 0.25) scores,(3.09 ±0.52) scores vs.(2.32 ±0.39) scores,t=14.81,15.36,9.42,P＜0.01 or 0.05].Conclusions Transitional care based on the Omaha system shows common problems in rehabilitation of patients with breast cancer after operation,and provides standardized program for rehabilitation nursing.It can achieve better nursing effect.

Objective To observe the destructive and scavenging effect of ambroxol (AMB) on the biofilm (BF) of Pseudomonas aeruginosa (P.a).To evaluate the synergistically bactericidal effect of AMB along with levofloxacin (LFX) on BF of P.a.Methods The early model (cultured for 3 d) and mature model (cultured for 7 d) of P.a wild strain (PAO1) BF were established,in vitro,respectively.The models were randomly (random number) divided into control group,AMB group and AMB + LFX group.The concentrations of AMB were 256 μg/ml and 512 μg/ml,respectively.When the early BF model and mature BF model were made,different concentrations of AMB were added in AMB group and AMB + LFX (1μg/ml) was added in AMB + LFX group.The number of viable P.a on the BF carrier was counted with the continuous dilution method 24 h after AMB or/and LFX added.Then,the BF morphological changes on the carrier surface were observed by using scanning electron microscopy (SEM).Measured data were analyzed with single factor analysis of variance (One-Way ANOVA).Results Both in the early BF model and in the mature BF model,the SEM examination showed that the BF in AMB group was significantly reduced compared to the control group,and this reduction of BF was in dose-dependent manner.LFX 1 μg/ml could reduce the number of viable bacterial in BF in both early model and mature model (P ＜ 0.05).LFX with addition of different concentrations of AMB showed stronger bactericidal effect than LFX used alone identified by more significant reduction in the number of colonv within the BF (P ＜ 0.05).Furthermore,the LFX combined with 512 μg/ml AMB reduced more significant number of colony apparently than the LFX combined with 256 μg/ml AMB (P ＜ 0.05).Conclusions AMB can destroy the early BF or mature BF partly,and LFX alone can partly reduce the number of viable P.a within BF.When LFX combined with AMB,they exert a synergistically bactericidal effect.
