ObjectiveTo study the effect of nursing quality of bull’s eye pattern on caring cancer patients with religious belief. Methods Three hundred and thirty-six cancer patients with religious beliefs were cared according to nursing quality of bull’s-eye pattern.All patients were evaluated by European organization for research and treatment of cancer quality of life questionnaire core 30(EORTC-QLQ-C30)before and after applications of nursing quality of bull’s-eye pattern and the results were compared.Result The scores of the dimensions of overall quality of life and function in EORTC-QLQ C30 questionnaire among those patients with implementation of nursing quality of bull’s eye patterns were higher than those before implementation of the pattern and the symptom score after the use of the pattern was statistically lower than that before its use in respect of dimensions of cancer symptoms(P<0.01). Conclusion The applications of nursing quality of bull’s-eye pattern on caring cancer patients with religious beliefs can improve the patients’ quality of life.

Objective To establish a method for quality control of oleanolic acid and ursolic acid in Qingdu tablet. Methods The content of oleanolie acid and ursolic acid in Qingdu tablet were determined by high performance liquid chroma-tography(HPLC). The analytical column was kromasil-C18 (250 mm × 4.6 mm, 5 μm). The mobile phase consisted of methanol-0.5% phosphoric acid solution (88:12). The UV detection wavelenghth was 210 nm. The flow rate was 1.0 ml/min. Results Oleanolic acid and ursolic acid showed a good linearity in range of 0.06-0.54μg (R=0.999 3) and 0.30-2.70μg (R=0.999 7). The average recovery rates of Oleanolic acid and ursolic acid were 100.48% and 102.21%, respectively. Conclusions This method is simple, rapid and accurate. It could be used for the quality control and quality study of the Qingdu tablet.

Objective:To study the effects of the overexpression of hsa-miR-202 on the proliferation and molecular mechanism of lung cancer A549 cells. Methods:A sequence of hsa-miR-202 with ppG/miR/eGFP/Blasitidin pasmid was directionally connected and a eukaryotic expression vector pmiR-202 of the target hsa-miR-202 gene was constructed. pmiR-202 was transtected to A549 cell with Lipofectamine 2000. The WST assay was used to detect the cell proliferation rate, and RT-PCR was used to detect the relative gene expression levels. Western blot analysis was used to detect the IL-10 protein expression levels. The interaction between miR-202 and IL-10 was examined using a luciferase reporter assay. Results:The design from the DNA sequencing results shows that a eukaryot-ic expression vector of miR-202 was successfully constructed. The proliferation inhibition rates of A549 cells by Pmir-202 were 12%, 38%, and 52%. The differences in the treatment group compared with the blank control and negative control groups were statistically significant. The RT-PCR results showed that the relative expression levels of miR-202 increased after transfection with pmiR-202. Over-expression of miR-202 can downregulate the relative gene and protein expression levels of IL-10, and the relative levels were 25%and 0.75, respectively. Compared with the blank control and the negative control groups, the difference was statistically significant (P<0.05). The fluorescent activity was reduced when transfection was performed with miR-202 mimics, and IL-10-3'UTR plasmid was cloned. Conclusion: pmiR-202 effectively inhibited the proliferation of A549 cells and exhibited a time-effect relationship with miR-202 by targeted combination with IL-10 3'UTR to downregulate IL-10 expression in A549 cells.

Haemophilia is caused by lack of coagulation factor VIII or IX in patients′blood with inadequate hemostasis.Currently recombinant coagulation factor VII(rFVII)produced in different cells is used against clini-cal bleeding of haemophilia patients.To enhance the production and activity of rFVII;some eukaryotic cells such as baby hamster kidney(BHK);Chinese hamster ovary(CHO);insect cell and fish embryo;were used to express rFVII.Meanwhile;the effect of functional gene on the activity of rFVII and the limitation of rFVII production caused by post-translational modification were investigated by different methods.The role of rFVII in hemostasis;synthesis of rFVII in different eukaryotic cells and impact on production of post-translational modification are reviewed in this article.

The current difference between male and female rabbit ventricular myocytes was investigated for elucidating the mechanism of longer QT interval and higher incidence of drug-associated torsade de pointes in female rabbits than in male rabbits. Whole cell patch clamp technique was used to record APD, Ito, IK,tail, IK1 and ICa,L of myocytes from left ventricular apex. There was no difference in the membrane capacitance between male and female rabbit myocytes. APD90 was longer in female rabbits (560.4+/-26.5 ms, n=15) than in male ones (489.0+/-20.7 ms, n = 14), P<0. 05. In female rabbit myocytes, IKtail, Ito, IK1 and ICa,L were 0.71+/-0.05 pA/pF (n=17), 8.28+/-1.03 pA/pF (n=18), 24.5+/-3.6 pA/pF (n=12) and 9.0+/-2.3 pA/pF (n=15) respectively. In male rabbit myocytes, they were 0.84+/-0.07 pA/pF (n=18), 8.60+/-1.20 pA/pF (n=18), 25.9+/-4.5 pA/pF (n=14) and 9.3+2.6 pA/pF (n=16) respectively. IK,tail in female rabbits was significantly lower than that of male rabbits (P<0.05), but there was no difference in Ito,IK1 and ICa.L between male rabbits and female rabbits (P>0.05). The lower IK.tail of female rabbit myocytes may contribute to the longer repolarization and the higher incidence of drug-associated torsade de pointes.

In order to confirm the hypothesis that during acute hypoxia, the antiarrhythmic peptide (AAP10) could improve conductance by changing the phosphorylation state of connexin43 (Cx43), isolated perfused rat hearts were randomly divided into three groups: control, hypoxia and AAP10 (n=9 in each group). The change in Cx43 phosphorylation was tested by Western-blot; the distribution of Cx43 was observed by confocal immunofluorescence microscopy. Western-blot analysis revealed that the expression of total Cx43 protein was significantly decreased during acute hypoxia, while nonphosphorylated Cx43 (NP-Cx43) was unchanged. AAP10 could increase the expression of total Cx43 protein, but had no effects on the NP-Cx43 protein. Immunofluorescence study showed that during acute hypoxia, both total Cx43 and NP-Cx43 proteins were greatly decreased, while AAP10 only increased the expression of total Cx43 protein, but had no effect of the NP-Cx43 protein expression. These findings suggested that the decrease of intercellular communication may be associated with the reduction of phosphorylated Cx43 (p-Cx43) and translocation of NP-Cx43 from the surface of gap junction into intracellular pools during acute hypoxia. AAP10 can improve intercellular communication by enhancing phosphorylation of Cx43.

Objective To investigate the effects of body-weight support treadmill training(BWSTT) on function of lower limbs.Methods 46 hemiplegic patients after stroke were randomly divided into the therapy group(n=23) and control group(n=23).The subjects of both groups were administered with standardized rehabilitation program.The therapy group was also given BWSTT in addition.Both groups were evaluated before and after treatment using Functional Ambulation Category(FAC),Fugl-Meyer Assessment(FMA),Berg Balance Scale(BBS).Results Before treatment,there was no significant difference between these 2 groups in terms of scores with FAC,FMA and BBS.After treatment,both groups were significantly improved regard to their scores with FAC,FMA and BBS(P<0.01),with the therapy group scored significantly better than the control group(P<0.01).Conclusion BWSTT can significantly improve walk ability and balance function of the hemiplegic patients after stroke.

Objective To investigate the effect of bed rest on acute nonspecific low back pain(ANLBP).Methods87 cases were randomly divided into bed rest group (42 cases) and free activity group (45 cases).The bed rest group would be proper activity indoor and step up activity outdoor after absolute in bed for a week.The free activity group would be prescribed free activity.At the same time,all of them received physiotherapy and non-steroidal anti-inflammatory drugs (NSAIDs).The visual analogous scale (VAS) were measured before and 2 weeks after treatment.The Roland-Morris disability questionnaire (RMDQ) were measured before and 2,6 weeks after treatment.ResultsThe difference of VAS and RMDQ scores between these 2 groups were not significant before treatment (P>0.05),but were significant 2 weeks after treatment(P<0.05).Further more,the difference of RMDQ scores between these 2 groups were not significant 6 weeks after treatment (P>0.05).ConclusionThe bed rest about patients could not promote,but delay the improvement of the pain and disability in the early period or later period recovery of ANLBP.
