ABSTRACT
With aging population becoming increasingly prominent, more intelligent, integrated, and anthropomorphic nursing robots are becoming an important option for future home-based elderly care. However, a series of ethical dilemmas may arise when nursing robots that provide long-term services participate in the social life of the elderly as social entities. For example, the encroachment of low-level interaction between humans and nursing robots on the high-level interaction between humans, as well as the dispute over the definition of responsibility caused by unclear moral subjects. The value sensitive design theory advocates incorporating value into technical design, and based on its conceptual research, empirical research, and iterative approach, it can be found that the fundamental reason for the above-mentioned ethical dilemma lies in the confusion and dislocation of the ternary nursing relationship among human caregivers, the elderly, and nursing robots. Accordingly, this paper proposed to clarify the user status of the elderly and human caregivers, while nursing robots serve as auxiliary tools to meet the nursing needs of the elderly, protect and enhance the well-being of the elderly.
ABSTRACT
Objective To investigate the role of MBP-1 in proliferation,apoptosis and invasion of human esophageal cancer cells Ec109.Methods The human esophageal cancer cells Ec109 were cultured,and divided into the MBP-1 mimics group,siRNA-MBP-1 group,negative control group and blank control group.The cell proliferation activity of each group was detected by tetrazolium blue (MTT) method;flow cytometry was used to detect cell apoptosis and cell cycle;Transwell assay was used to detected the invasion ability and the expressions of cellular cycle related C-myc,Cyclin D1 and Cyclin E were detected by western blot.Results Compared with the negative control group and blank control group,the expression of MBP-1 in esophageal cancer cells Ec109 of the MBP-1 mimics group was up-regulated (P＜0.05),the proliferation ability of esophageal cancer cells was decreased,increased the proportion of apoptosis,decreased the proportion of G0/G1 phase cells,inhibited the number of invasive cells was decreased and the expressions of C-myc,Cyclin D1 and Cyclin E proteins.After silencing MBP-1,the expression of MBP-1 in esophageal cancer cells Ec109 in the siRNA-MBP-1 group was down-regulated,the proliferation ability of esophageal cancer cells was increased,the proportion of apoptosis was decreased,the proportion of G0/G1 phase cells was increased.the number of invasive cells was increased and the expressions of C-myc,Cyclin D1 and Cyclin E proteins were up-regulated.Conclusion MBP-1 is closely correlated with the cell proliferation,cell apoptosis and invasion ability of human esophageal cancer cell line Ec109,and its mechanism might be related to cell cycle abnormality.
ABSTRACT
Objective To retrospectively analyze the anesthesia management of applying minimally invasive percutaneous neplrolithotripsy for treating hepatolithiasis.Methods The anaesthesia method,anesthetic effect,the time of resuscitation after anesthesia and side -effect of anesthesia in 86 patients who were underwent minimally invasive percutaneous neplrolithotripsy for hepatolithiasis were analyzed.Results All 86 patients were satisfied with anesthetic effect and completed surgery successfully.Among them,48 patients underwent operation with epidural anesthesia,31 patients with general anesthesia and 7 patients with the management of anesthesia monitoring(MAC) plus with local anesthesia.The time of resuscitation after anesthesia in general anesthesia patients was longer than those of epidural anesthesia and MAC.6 patients were delayed recovery and hypothermia after general anesthesia, 4 cases of epidural anesthesia and 1 case of MAC appeared cholecyst -heart reflection,and 2 cases of epidural anesthesia vomiting intraoperation.Conclusion The rational anesthesia method for patients underwent minimally invasive percutaneous neplrolithotripsy for treating hepatolithiasis should consider reasonably heart and lung function, maintain hemodynamics and respiratory stably,pay attention to insulation intraoperation,prevent cholecyst -heart reflection and shorten the operation time,which can reduce the side -effect of anesthesia and were favor for recovery after operation.

ABSTRACT
Objective To investigate the clinical efifcacy of Tiotropium Bromide inhaler on patients with stable chronic obstructive pulmonary disease(COPD). Methods 134 cases with stable COPD were equally randomized into three groups. The conventional treatment group(n=46) were 40 male and 6 femal, aged (63.20±9.3)years old and treated with sustained-release theophylline 0.1 g orally. Observation group with 18μg Tiotropium Bromide(n=45) were 40 male and 5 femal, aged (63.4±85)years old, and given inhaled Tiotropium Bromide 18μg. Observation group with 32μg Tiotropium Bromide(n=43) were 39 male and 4 femal, aged (63.2±9.0)years old, and given inhaled Tiotropium Bromide 32 μg. All patients received same routine therapy, and lasted for 4 weeks. improvement Pre-and post-treatment Lung function and quality of life were compared among those groups. Results In observation group, the results of St George respiratory questionnaire decreased signiifcantly after treatment, which was signiifcantly lower than those of the routine-treatment group (P<0.05). FEV 1/FVC, FEV 1/Pred, FEV 1 were signiifcantly higher than those before treatment (P<0.05). However, the control group showed no signiifcant difference. Conclusion Inhaled Tiotropium Bromide can improve lung function and life quality of paitents with stable COPD, the dose with 32μg per day, which was signiifcantly lower than 18μg per day.
ABSTRACT
BACKGROUND:Inflammatory cellactivation and the generation of oxygen free radicals are important factors of lung ischemia-reperfusion injury. Adding the drugs with anti-inflammation and antioxidant effects into the lung preservation solution used, can improve the protection fluid, and play a crucial role in the study of lung ischemia-reperfusion injury and protection of the function of transplanted lung. OBJECTIVE:To discussion the effect of harmine in canine model of pulmonary ischemia-reperfusion injury. METHODS:Twelve healthy hybrid dogs were randomly divided into two groups, with six rats in each group. A canine model of lung ischemia-reperfusion injury was established, and the protecting liquid was perfused with the clockwise irrigation method. Control group:low potassium dextran protective fluid;experimental group:low potassium dextran+harmine protective fluid. After 2 hours of ischemia, the left lung circulation was recovered. The left lung tissue and blood samples were col ected from two groups of animal models after reperfusion, and their cytokines levels and the lung wet/dry weight ratio were detected and calculated. Bronchoalveolar lavage fluid was col ected to observe the pathological indicators. The main pulmonary artery pressure, left and right pulmonary artery pressure were recorded by continuous monitoring. RESULTS AND CONCLUSION:There were no statistical y significant differences in the interleukin-17, tumor necrosis factorαand endothelin 1 content in the left lung tissue and the blood between the two groups at 2 and 4 hours after reperfusion (P>0.05). After 4 hours of reperfusion in both groups, the neutrophil number, the number of lymphocytes, alveolar edema index, and vascular wal damage in bronchoalveolar lavage fluid showed no statistical y significant differences (P>0.05). Through the analysis of variance, the main pulmonary artery pressure, left pulmonary artery pressure and right pulmonary artery pressure also had no statistical significance between the two groups (P>0.05). By the analysis of cytokines, pathological indicators, lung wet/dry weight ratio, and pulmonary arterial pressure, harmine has no significant lung protection effect in canine model of lung ischemia-reperfusion injury.
ABSTRACT
Objective To investigate the effect of auxiliary heterotopic partial liver transplantation in treating acute ischemic liver failure. Methods Auxiliary heterotopic partial liver transplantation was performed on pigs.The pigs were divided into two groups.Group I: The host′ liver was preserved in situ, liver artery was ligated, portal vein was constricted,and donor patial right liver was transplanted under the right lobe of the liver of the host.Portal venous blood supply was constructed only, and arterial blood supply was not constructed .Group B:Except both arterial blood supply and portal venous blood supply of the donor liver were constructed, and the other operative procedures were as the same as in Group A. The living condition, liver function, blood supply, pathology and bile secretion of the donor liver were observed. Results The survival rates in Group B before and after operation were higher than that in Group A .Serum bilirubin(SB) after the operation was higher than that before the operation in Group A, but showed no change in Group B.After the operation, SB in Group A was higher than that in Group B. In Group A, the donor liver didn't secret bile,and hepatocytes were necrosis.In Group B, the bile secretion and blood supply of donor liver were good,and hepatocyte of the donor liver were alive and proliferating actively.The hosts' liver was necrosis obviously in both groups. Conclusions Hosts' liver artery ligation and portal vein constriction can result in acute ischemic liver failure.Auxiliary heterotopic partial liver transplantation is effective in correcting liver failure.The good arterial blood supply must be constructed in the donor liver to get good donor liver quality.
