DynaPulse, a newly developed noninvasive apparatus, is valuable in assessing blood pressure, cardiac output and vascular compliance. The purpose of the present study was to evaluate the validity of cardiac output measurement using DynaPulse in patients, compared with echocardiography and Fick method. Forty five inpatients underwent cardiac output measurement using DynaPulse (CO DP ) and Doppler echocardiography (CO DE ), cardiac output was measured with DynaPulse (CO DP ) and Fick method (CO FM ) in additional 26 patients. A good correlation was found between CO DP and CO DE ( r =0 76). There was an acceptable correlation between CO DP and CO FM ( r =0 61). DynaPulse can provide a noninvasive, clinically useful estimation of cardiac output.

Objective To explore the relationship between recurrence fear and coping styles of cancer patients. Methods This study was a cross-sectional study, using the convenience sampling to select 126 inpatient cancer patients as the research object. The Fear of Progression Questionnaire-Short Form (FoP-Q-SF) and Medical Coping Modes Questionnaire (MCMQ) were used. Results The Fear of Progression score was (29.97 ± 9.24) points,the mean score of items was (2.50 ± 0.77) points, and the face dimensions of coping styles was (2.55±0.35) points, the avoidance dimension was (2.54±0.35) points, and the yield dimension was (2.38±0.54) points. Different gender (F=4.36,P<0.05) and marital status (F=3.22, P<0.05) of cancer patients in social family dimension of recurrence fear was statistically significant, different gender of cancer patients in avoid disease dimension was statistically significant (F=6.59,P<0.05). The yield dimension in coping style was positively correlated with the recurrence of cancer (r=0.481, P<0.05). Conclusions The recurrent fear of cancer patients with women, divorce and surrender coping strategy is prominent, women tend to take avoid coping strategy in response to disease. Therefore, it′s important to focus on women and divorced people in the psychological intervention of tumor patients, and guide patients to adopt the positive coping style to reduce the recurrence fear.

Bronchial asthma is a kind of respiratory disease which affects people 's life quality seriously. Many factors in-volved in the occurrence and development of such disease, of which the aberrant expression of E-cad plays a critical role in it. Research found that E-cad is an important cell adhesion molecu-lar, and its main function is to maintain the structural integrity of cells and participate in the improvement of airway remodeling as well as restoration of immune function. Further study showed that the role of mucosal barrier of airway epithelial cells in bronchial asthma patients was often damaged. Moreover, the protein ex-pression of E-cad decreased significantly in mucosal molecular, which suggested that the abnormal expression of E-cad was in-volved in the development of bronchial asthma. A review on the relations between the abnormal expression of E-cad protein and bronchial asthma has been discussed in this paper, also it in-cludes the discussion about the mechanisms of E-cad’ s disorder-induced bronchial asthma as well as explores the strategies of bronchial asthma treatment, which may provide references for the follow-up research and clinical treatment.

Objective:To explore a new way of pharmaceutical service mode for disease treatment. Methods:Clinical pharmacists actively participated in the pharmaceutical care for a patient with mixed liver injury, and provided clinical pharmaceutical services through the adverse reaction analysis,etiological mechanisms exploration,therapeutic drugs selection and risk factors prevention. Re-sults:Clinical pharmacists cooperating closely with physicians helped to identify problems in time,and then the medication analysis in the fields of drug selection, dose determination, efficacy evaluation and indicators detection was performed, so that the strategies on medicine treatment could be adjusted timely as the disease progressed. With the gradual recovery of liver function, the patient dis-charged after the conditions were improved. Conclusion:By participating in pharmaceutical practice,clinical pharmacists can provide clinical pharmaceutical service,which is helpful to safety improvement and efficiency of drug administration. It is also an effective way to enhance the learning ability of pharmacists,and cultivate their clinical thinking and practice capacity.

Objective To investigate the mechanism and protective effect of Humanin(HN)on rotenone(Rot)-induced toxic damage for dopamine neurons.Methods The Rot-poisened PC12 cell model was constructed,and the control group,the Rot poisening group,the HN pretreated Rot poisening group,and the HN treatment group were set up.ELISA was used to detect the content of HN inside and outside of Rot-infected cells,CCK-8 assay was used to detect cell viability,and ATP detection kit was used to detect the intracellular ATP content.Dichloro-dihydro-fluorescein diacetate(DCFH-DA)assay was used to detect the level of reactive oxygen species(ROS)in cells.Western blotting was performed to detect the expression level of mitochondrial autophagy regulatory proteins Pink1,Parkin,p62,LC3,mitochondrial biogenesis regulatory protein PGC1α,division/fusion regulatory proteins OPA1,MFN2,DRP1,p-DRP1 and antioxidant stress regulatory proteins Keap1 and Nrf2.HBAD-mcherry-EGFP-LC3 adenovirus transfected cells was used to observed the number of autophagosomes and autophagolysosomes.Results The results showed that the intracellular concentration of HN in PC12 in the Rot poisening group was significantly higher than that in the control group(P<0.05);Compared with the control group,the Rot poisening group had significantly decreased activity of PC12 cells,decreased ATP content and increased production of ROS.After the poisen of Rot in PC12 cells,the expression of Pink1 and p-Parkin,the ratio of LC3Ⅱ/LC3Ⅰ and the expression of p-DRP1 in mitochondrial fusion protein was increased,while the expression of p62,the expression of mitochondrial biogenesis protein PGC1 α,mitochondrial fusion proteins MFN2 and OPA1,and antioxidant stress proteins Keap1 and Nrf2 were decreased(all P<0.05).The number of autophagosomes and autophagolysosomes in PC12 cells in the Rot poisening group was higher than that in the control group(P<0.05),and HN pretreatment(20 μmol/L)could significantly improve the changes mentioned above caused by Rot poisening(P<0.05).Conclusion HN ameliorates Rot-induced toxic damage for dopamine neurons by inhibiting mitophagy and mitochondrial division and promoting mitochondrial biogenesis and fusion,and anti-oxidative stress.
