Objective To investigate the recognition of graded nursing and its influencing factors among nursing assistants in elder homes.Methods A questionnaire survey was conducted on 116 nursing assistants.Results The nursing assistants showed insufficient recognition of graded nursing,there were significant differences in role cognition,operation and practice training,salary,and the nursing workload,there were no significant differences in working years and educational levels.Conclusions The recognition of graded nursing was insufficient.It is suggested to increase the role cognition education,enhance the theory and practice training,provide higher salaries and allocate workload reasonably to ensure the implementation of graded nursing and increase the satisfaction level of the elderly.

Gastrodia elatais graded as top medication in theShen Nong’s Herbal Classic. It was mainly distributed in southwest China. Its quality varied with geographical location. And the quality difference between wild and cultivated sample was extreme. Identifications using traditional methods were unable to accurately distinguish the quality ofG. elata. Therefore, near-infrared (NIR) spectroscopy combined with pattern recognition method was used to distinguish the quality ofG. elata from different geographical locations as well as cultivated or wild. The results demonstrated that using NIR spectroscopy combined with multiclass classification algorithm, the geographical location ofG. elata can be accurately distinguished. The prediction accuracy can reach as high as 94.3% and 96.4% for both applications. Besides, the classification model was built without preprocessing; hence, it can be extended to be applied on-site.

A 36-year-old female presented with multiple dark brown papules on the chest and abdomen for more than 10 years,which had gradually increased in number.Physical examination revealed dozens of dark brown,flat papules measuring 1-3 mm in diameter in the chest and abdomen.Most of the lesions had a smooth surface,and some lesions gave a papilloma-like appearance,with no confluent trend.Biopsy of abdominal lesions showed mild hyperkeratosis of epidermis,acanthosis,extension of epidermal protrusions forming a reticulated appearance,horn pseudocysts in prickle cell layer,enhanced pigmentation of basal layer,and a sparse lymphocytic perivascular infiltrate in superficial dermis.A diagnosis of dermatosis papulosa nigra (DPN) was made.

OBJECTIVE:To train the students’ability about true-and-false identification of pini pollen,typhae pollen and Lygo-dium japonicum. METHODS:Teachers firstly used flexible and diversifided teaching methods to train the learning interest of stu-dents,and then picture antithesis,classroom presentation and other methods were used to teach the distinctive features between the true and false traditional Chinese medicine in the characters of identification. RESULTS&CONCLUSIONS:There were obvious dif-ference among the colors,physicochmical poperties,microscopic characteristics and other aspects of 3 traditional Chinese medi-cines. According to the teaching,the students could not only distinguish the 3 traditional Chinese medicines accurately, but also could identify the true-and-false of them. picture antithesis and classroom presentation method are simple and vivid, and can be used for the training of students’ability about true-and-false identification.

Objective To explore the effects of low frequency electric stimulation at bilateral mastoid processes on motor function and cerebral blood flow of children with cerebral palsy (CP). Methods Ninety children with CP were randomly divided into two groups: an electric stimulation group (group 1) and an conventional rehabilitation control group (group 2), thirty healthy children served as the normal control group. The children of group 1 were treated with FES in addition to the routine rehabilitation treatment. The children of group 2 were given of the routine rehabilitation treatment only. All the patients were treated successively with the above protocol for 3 months. The clinical effect and motor development were evaluated with the gross motor function measure (GMFM), and the blood flow velocities of anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA) were measured by transcranial doppler (TCD) ultrasound before and after treatment. Results In group 1, significant or some improvement were achieved in 19 and 24 CP children, respectively, with an effective rate of 95.6% . In group 2, significant or some improvement were achieved in 10 and 27 CP children, respectively, with an effective rate of 82.2%. There was significant difference between the two groups with regard to the significant effective rate (P

Objective To explore the curative effect of local oxygen therapy in combination with external application of Houfengsan and vitamin AD mixture in the treatment of red breech. Methods 100children with red breech were divided randomly into the treatment group and the control group with 50 cases in each group. The treatment group was treated with direct local oxygen blowing for 10～15 minutes and applying mixture of Houfengsan and vitamin AD, the control group was treated with 3% zinc oxide unguent.The treatment effect and cure time were compared between the two groups. Results The total efficient rate of the treatment group was 100% ,which was higher than that of the control group. The cure time of the treatment group was (3.92±0.98) days ,and (6.66t1.46) days in the control group, and the difference was significant between the two groups. Conclusions Local oxygen blowing with external application of mixture of Houfengsan and vitamin AD is easy to accept by children, safe, economical and simple to operate. It is an effective method to treat red breech.

Mechanics plays an important role in regulating cell function. Hydrodynamics has become a hot topic of research in recent years. As an important factor, hydrodynamic pressure has significant influence on the form, cytoskeleton, proliferation, apoptosis and secretion function of cells. Many researches indicated that there are close relationships between kidney diseases and hydrodynamics which should be studied deeply.

BACKGROUND:In recent years, calcium alginate dressing has been widely used in surgical hemostasis, traumatic hemostasis, postoperative nasal hemostasis and puncture site hemostasis,etc.; however, there are few reports on their hemostatic mechanisms. OBJECTIVE: To preliminarily study the hemostatic mechanism of calcium alginate dressing. METHODS: Human anticoagulant blood was respectively dropped on sodium alginate dressing, nasopore dressing and medical cotton gauze. After 2 minutes, the interaction between materials and blood was observed at the room temperature using scanning electron microscopy. Calcium alginate dressing, nasopore dressing and medical cotton gauze were added in human red blood cel suspensions respectively. After 15 minutes, the interaction between materials and red blood cels was observed using scanning electron microscopy. The red blood cels were suspended by different concentrations (10, 5, 2.5 g/L) of alginate dressing extracts. The erythrocyte sedimentation rate was observed at different time points (30, 60, 120 minutes). Platelets rich plasma was incubated with different concentrations (10, 5, 2.5 g/L) of alginate dressing extract at 37℃, then CD62P positive platelet percentage was measured by flow cytometry after 10 minutes of incubation. RESULTS AND CONCLUSION: Dense fibrin network was formed after calcium alginate dressing contacting with an anticoagulant. A large number of blood cels were recruited. There were only a smal amount of red blood cels and platelets adhesion in the nasopore dressing and medical cotton gauze groups. After the calcium alginate dressing interacting with red blood cels, red blood cel deformability was visible, with a pseudopodia-like change. The red blood cel morphology was unchanged in the nasopore dressing and medical cotton gauze groups. The calcium alginate dressing extract dose-dependently and time-dependently increased the red blood cels aggregation, comparative differences between groups was statisticaly significant(P < 0.01). The calcium alginate dressing extract dose-dependently enhanced the CD62P positive platelet percentage, comparative differences between groups was statisticaly significant (P< 0.01). These results demonstrate that calcium alginate dressing promotes hemostasis and coagulation process by releasing of calcium ions, causing red blood cel aggregation and deformation and activating platelets.
