Objective To investigate the inpatients' evaluation of quality nursing care and disucss different data collecting methods on patients's evaluation of quality nursing care. Methods Patients measure up to standard (82 cases) were divided into the questionnaire group and the interview group with 41 patients in each group. The questionnaire investigation was carried out in the questionnaire group by applying 4 themes of quality nursing care. The interview group used structured interview instead. The results of the two methods were compared and analyzed. Results The score of quality nursing care of the questionnaire group was higher than that of the interview group (P<0.01) in evaluating health education method. In humanistic environment patients in the questionnaire group thought nurses could protect their privacy, respect their personality and treat them and their family members kindly. Besides visiting institution was reasonable. All of these were the demonstration of quality nursing care. The above results were different from those of the interview group (P<0.01). Conclusions Patients had comprehensive requirement on quality nursing care. Nurses should, use this as reference, regulate their service behavior and improve nursing quality.

Objective To investigate the immunological reaction mechanism of medicated serum in Zibai Gelatin for SiHa cells of the cervical cancer infected by high risk human papilloma virus (HPV). Methods Through immunohistochemical comparison and the cell culture, and after medicated serum was administrated to SiHa cells of cervical cancer for 24 h, 48 h, and 72 h, optical densities of IL-6, IL-10, CD83 and TNF-αin the same time but different concentrations and different times but the same concentration were observed. Relationships of dose-effect and time-effect between expressions of IL-6, IL-10, CD83 and TNF-α and medicine action were analyzed by calculating average optical density. Results With the increase of medicine concentration and administration time of Zibai Gelatin, the expressions of IL-6 and TNF-αgradually decreased, while the expressions of CD83 and IL-10 gradually increased (P<0.05). Conclusion Zibai Gelatin with medicated serum can inhibit local inflammatory reaction by improving local immunologic function of cervix, which is beneficial to reduce cervix high-risk HPV.

AIM: To evaluate the changes of microRNA (miRNA) in hepatocytes during hydrogen peroxide-induced oxidative stress injury, and to observe the alleviating effect of mesenchymal stem cell-conditioned medium (MSC-CM) in this progress.METHODS: The hepatocyte oxidative stress injury model was established using hydrogen peroxide and human normal liver cell line L02.MSC-CM was prepared using centrifugation and filter.The effects of MSC-CM on hepatocyte injury were evaluated by apoptosis analysis, cell viability detection, cell cycle, and mitochondrial membrane po-tential (MMP).Twenty-one differentially expressed miRNAs were selected by gene chip hybridization, in which miR-143, miR-145, miR-301a and let-7a were confirmed by RT-qPCR.Bioinformatics software was utilized to predict target proteins of these miRNAs, and then the proteins were verified by Western blot.RESULTS: MSC-CM markedly attenuated hydrogen peroxide-induced oxidative stress injury by reducing apoptosis, promoting cell viability and regulating cell cycle.The ex-pression of miR-143, miR-145, miR-301a and let-7a, indentified by RT-qPCR, increased under the condition of oxidative stress injury, while decreased after MSC-CM treatment.The expression of miR-143 predicted target proteins, HK2 and ADRB1, decreased under the hydrogen peroxide-exposure, while increased after MSC-CM treatment, which is consistent with the regulatory trend of miR-143.CONCLUSION: MSC-CM might attenuate hydrogen peroxide induced oxidative stress injury via inhibiting apoptosis and regulating some miRNA expression.

Objective To observe the preventive effects of puerarinon development of deep vein thrombosis (DVT) in elderly women with osteoporosis after hip replacement. Methods 100 elderly women with osteoporosis who scheduled for femoral head arthrolastybetween January 2012 and January 2014 in Cangzhou Central Hospital were selected and then randomly divided into a study group (n=50) and a control group (n=50). The control group received routine anti?inflammatory and anticoagulant therapy ,while the study group received intravenous drip of puerarinof 400 mg mixed with 5%glucose liquid 500 ml daily for 15 days as a treatment course. After the treatment, DVT incidence rate ,change of early diagnostic indexes and hemorheology were compared with their baselines. Results DVT incidence rate was significantly lowerin the study group than in the control group (8.0%vs. 24.0%, P<0.05). Ascompare with the control group,thromboxane A2/prostacyclin,plasma homocysteine and hemorheology?were significantly reduced (P < 0.05). Conclusions Puerarin has a preventive effect for deep vein thrombosis in elderly women with osteoporosis after hip replacement.

Objective To evaluate the role of p38 mitogen-activated protein kinase (p38MAPK)-heat shock protein 27 (HSP27) signaling pathway in attenuation of lipopolysaccharide (LPS)-induced acute lung injury (ALl) by dexmedetomidine in mice.Methods Forty male Kunming mice,aged 2 months,weighing 20-25 g,were equally and randomly divided into 4 groups using a random number table:control group (group C),LPS group,low-dose dexmedetomidine + LPS group (group D1),and high-dose dexmedetomidine + LPS group (group D2).Dexmedetomidine 25 and 50 μg/kg were injected intraperitoneally in D1and D2 groups,respectively,and 1 h later LPS 5 mg/kg was injected intraperitoneally.At 6 h after LPS injection,the left lung was lavaged,and broncho-alveolar lavage fluid (BALF) was collected for determination of concentrations of protein,tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β).The right lung was removed for examination of the pathological changes (under the light microscope) and for detection of expression of phosphorylation of p38MAPK (p-p38MAPK),p38MAPK,phosphorylation of MAPK-activated protein kinase 2 (p-MAPKAPK-2),MAPKAPK-2,phosphorylation of HSP27 (p-HSP27) and HSP27 in lung tissues.The wet to dry lung weight (W/D) ratio was calculated.The ratios of p-p38MAPK/p38MAPK,p-MAPKAPK-2/MAPKAPK-2 and p-HSP27/HSP27 were calculated.Results Compared with group C,the W/D ratio,concentrations of protein,TNF-α and IL-1β in the BALF,and ratios of p-p38MAPK/p38MAPK,p-MAPKAPK-2/MAPKAPK-2 and p-HSP27/HSP27 were significantly increased in group LPS.Compared with group LPS,the W/D ratio,concentrations of protein,TNF-α and IL-1β in the BALF,and ratios of p-p38MAPK/p38MAPK,p-MAPKAPK-2/MAPKAPK-2 and p-HSP27/ HSP27 were significantly decreased in D1 and D2groups.The pathological changes of the lung were significantly reduced in D1 and D2 groups as compared to LPS group.Conclusion Dexmedetomidine attenuates LPS-induced ALI in mice possibly through inhibiting p38MAPK-HSP27 signaling pathway.

OBJECTIVETo detect the most prevalent mutations, R778L and P992L of ATP8B gene, in Chinese Wilson disease(WD) patients by high resolution melting (HRM) analysis after polymerase chain reaction (PCR).

METHODSGenomic DNA was extracted from peripheral blood samples obtained from 30 cases of WD by the standard phenol/chloroform method. DNA fragments encompassing ATP7B exons 8 and 13 were produced by PCR amplification. The amplicons containing the R778L or P992L mutations were then generated by nested PCR. The nested PCR products were subjected to HRM analysis using the HR-1 instrument. Mutations detected in HRM analysis were verified by restriction analysis using restriction enzyme (MspI or AluI or AfaI) or DNA sequencing.

RESULTSHRM analysis of the fragments encompassing ATP7B exon 8 showed four curve patterns. Subsequent restriction analysis and DNA sequencing proved that the four different curves represent four different genotypes: the wild type, the R778L/R778L homozygote, the R778L heterozygote, and the R778L/752.33delG compound heterozygote. Three HRM curve patterns were observed for the fragments encompassing ATP7B exon 13, representing the wild type, the P992L heterozygote, and the P992L/S975Y compound heterozygote. In our studied samples, allele frequencies of the R778L, P992L and S975Y mutations were 25%, 15% and 1.67%, respectively.

CONCLUSIONHRM analysis is a simple, accurate and sensitive approach for rapid detection of the ATP7B mutations and could be used as an optimized method for genetic testing in WD.

Objective To explore the effects of ADAR1 inducer and inhibitor on cognition and ADAR1 expression of isolated BALB/c mice.Methods Sixty healthy BALB/c mice were divided into 6 groups according to randomized design with 10 animals each group,the gregarious control group (GH),social isolation model group (SI),ADAR1 inducer treated gregarious group (GH+IFN-γ),ADAR1 inhibitor treated gregarious group (GH+EHNA),ADAR1 inducer treated isolation group (SI+IFN-γ) and ADAR1 inhibitor treated isolation group (SI+EHNA).Mice in drug treatment groups were treated with ADAR1 inducer (5.0? 104 U/kg,20 ml/kg,ip) and inhibitor (10 mg/kg,20 ml/kg,ip).Objection recognition test was used to measure cognition.Immunohistochenmistry was used to measure ADARI immunoreactivity and Western blotwas used to measure ADAR1 protein expression.Results In the objection recognition test,the non-spatial discrimination index of mice in SI group (-0.16±0.09) was significantly lower than that of GH group (0.41 ±0.17,P＜0.01),the non-spatial discrimination index of mice in SI+IFN-γ group (0.20±0.09) and in SI+ EHNA group (-0.29±0.12) was higher (P＜0.01) and lower (P＜0.05) than that of the SI group respectively.The immunohistochemistry results showed that the ADAR1 immunoreactivity in hippocampus of mice in SI group (Hilus:(0.013±0.003),CAI:(0.021±0.005)) decreased significantly compared to those of GH group(Hilus:(0.021 ±0.002),(0.047±0.004);both P＜0.05).And GH+IFN-γgroup mice showed increased ADAR1 immunoreactivity obviously in Hilus ((0.013±0.003) vs (0.023±0.004),P＜0.01) and in CA1 ((0.021±0.005) vs (0.040±0.005),P＜0.01) compared with that of SI group,ADAR1 inducer recovered the above abnornal ADAR1 immunoreactivity.Western blot results showed that the ADAR1 protein expression of mice in SI group (0.48 ±0.07) in hippocampus was significantly decreased (P＜0.01) compared to that of GH group (1.00 ±0.00).The level of ADAR1 protein in SI+IFN-γgroup(0.82 ±0.04) increased compared with that of SI group.Conclusions Four weeks of social isolation can reduce the non-spatial cognitive ability of BALB/c mice and decrease the expression of ADAR1 in the hippocampus.The ADAR1 inducers and inhibitors can reverse and aggravate the cognitive impairment caused by social isolation respectively.The related mechanisms may be related to the expression of ADAR1.

Objective:To investigate the effect of adenosine deaminase acting on RNA 1 (ADAR1) on 5-serotonin-2c receptor in alleviating aggression in socially isolated mice.Methods:Sixty healthy male BALB / c mice aged 21 days were randomly divided into six groups: social isolation group, social control group, ADAR1 inducer social isolation group, ADAR1 inhibitor social isolation group, ADAR1 inducer social control group and ADAR1 inhibitor control group.The mice fed in single cage for 4 weeks were used as social isolation model while the mice fed in group were used as control group.ADAR1 inducer (5.0×10 4 U/kg) and inhibitor (10 mg/kg) were given intraperitoneally to mice in the ADAR1 inducer social isolation group and the ADAR1 inhibitor social isolation group respectively.The aggressive behavior of mice was evaluated by resident-intruder test.The expression of ADAR1 and 5-serotonin-2c receptors in the brain of mice was detected by immunohistochemistry and Western blot. Results:The attack latency of social isolation group was significantly lower than that of social control group ((43.15±6.99) s, (542.40±30.50) s; t=15.906, P<0.01), and the latency of attack ((256.70±29.49) s) in the ADAR1 inducer social isolation group was significantly higher than that in the social isolation group ( t=7.046, P<0.01). The latency of attack ((15.25±2.18)s) in the ADAR1 inhibitor social isolation group was significantly lower than that in the social isolation group ( t=3.809, P<0.01). The optical density of ADAR1 immunoreactive cells in the amygdala of the social isolation group mice was significantly lower than that in the corresponding brain area of the social control group (BLA: (0.038±0.002), (0.074±0.004); LaDL: (0.033±0.002), (0.060±0.002); LaVM: (0.045±0.003), (0.073±0.004); Lavl area: (0.044±0.003), (0.070±0.003); t=8.428, 9.037, 6.462, 5.698, all P<0.01). The optical density of ADAR1 immunoreactive positive cells in the amygdala (BLA: (0.060±0.003), LaDL: (0.042±0.002), LaVM: (0.056±0.004), Lavl: (0.054±0.003) in the ADAR1 inducer social isolation group was significantly higher than those in the corresponding brain area of the social isolation group mice ( t=6.055, 2.876, 2.312, 2.492; all P<0.05). The expression of ADAR1 protein and 5-serotonin-2c receptor protein in amygdala of social isolation group were significantly lower than those of social isolation group ( t=11.37, 12.65; P<0.01). The expression of ADAR1 protein and 5-serotonin-2c receptor protein in the amygdala of the ADAR1 inducer social isolation group were significantly higher than those of the social isolation group ( t=3.02, 4.401; P<0.05). Conclusion:ADAR1 inducer alleviates the aggressive behavior of social isolated BALB / c mice by enhancing the protein expression of 5-serotonin-2c receptor in the amygdala of social isolated BALB/c mice.
