Research on the Ethical Dilemmas of Nursing Robots Assisted Home-based Elderly Care: Based on Value Sensitive Design Theory / 中国医学伦理学

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.

Observation of myrtol combined with cefazolin sodium pentahydrate in the treatment of pediatric acute suppurative otitis media / 中国耳鼻咽喉头颈外科

OBJECTIVE To investigate the effectof Myrtol combined with Cefazolin Sodium Pentahydrate in the treatment of acute suppurative otitis media in children. METHODS Totally 120 cases of pediatric acute suppurative otitis media were selected in our hospital from January 2014 to January 2016 and randomly divided into four groups, treated with Myrtol combined with Cefazolin Sodium Pentahydrate, Myrtol combined with Cefazolin Sodium, Cefazolin Sodium Pentahydrate, or Cefazolin Sodium, respectively. The effect and adverse reactions of the 4 groups were studied and compared. RESULTS There was no significant differences in age, sex, and average course of disease among the four groups. In Myrtol combined with Cefazolin Sodium Pentahydrate group, the clinical efficacy is better than that of the other three groups (P0.05), and both of them are better than cefazolin sodium group(P0.05). CONCLUSION Myrtol combined with Cefazolin Pentahydrate Sodium treatment was superior to the other three protocols in clinical efficacy for children with acute suppurative otitis media , and does do not increase the risk of safety.

Effects of CPP-ACP paste on the shear bond strength of orthodontic brackets.

OBJECTIVE: To evaluate the effect of casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste on shear bond strength and debonding failure modes of orthodontic brackets. MATERIALS AND METHODS: Freshly extracted premolars were randomly divided into four groups (n =18) as follows: in groups 1 and 3, the enamel was treated with a solution of CPP-ACP dissolved in artificial saliva; groups 2 and 4 served as controls, and the enamel was treated with artificial saliva. After conventional acid etching, in groups 1 and 2, brackets were bonded using a light-cured bonding system (Blugloo); while in groups 3 and 4, brackets were bonded using a conventional bonding system (Unite Bonding Adhesive). Bonded specimens were subjected to thermal cycling for 1000 cycles before debonding procedures. After debonding, teeth and brackets were examined under a stereomicroscope at 10x magnification to determine whether any adhesive remained, in accordance with the adhesive remnant index. The acid-etched enamel surfaces were also observed using scanning electron microscopy after treatment with and without CPP-ACP paste. RESULTS: The shear bond strengths of group 1 were significantly higher than those seen in group 2 (P < .01). There was no significant difference in the shear bond strengths of groups 3 and 4 (P > .05). Scanning electron microscopic observation showed that the pretreated enamel surface was rougher than that of the control surface after acid etching. CONCLUSION: The use of CPP-ACP can be considered as an alternative prophylactic application in orthodontic practice since it did not compromise bracket bond strength.

Relationship Between Plasma Fibrinogen Level and Ischemic Stroke in Patients with Nonvalvular Atrial Fibrillation / 国际脑血管病杂志

Objective:To investigate whether the increased plasma fibrinogen level is an independent predictor of cardiogenic embolism in patients with nonvalvular atrial fibrillation (NVAF).Methods:Ninety-eight patients with NVAF hospitalized for cardiac causes were evaluated,and 24 of them had a history of ischemic stroke.The relationship between fasting plasma fibrinogen level and ischemic stroke were analyzed.Results:After adjusting traditional cardiovascular risk factors.the patients with NVAF who had the history of ischemic stroke were significantly older than those without(mean [SD] age 73.6 [8.4]vs.69.1[10.3] years,P=0.017).1he prevalence of hypertension was significantly higher(83.3%va.66.2%,P=0.011).The proportion of patients with left ventricular systolic dysfunction was significantly higher(63.1% vs.45.9%,P=0.006),and plasma fibrinogen level increased significantly (mean [SD] 365 [108]vs.312[82] mg/dL,P=0.008).Conclusions:Plasma fibrinogen level is independently associated with a history of ischemic stroke in older patients with NVAF hospitalized for cardiac causes.
