Objective To evaluate the efficacy of midazolam combined with remifentanil for lower eyelid blephamoplasty.Methods In a double-blind study,200 patients undergoing lower eyelid blephamoplasty were randomly and equally divided into 2 groups (100 cases each):test group (midazolam 0.05 mg/kg and remifentanil 0.5 μg/kg followed by remifentanil 0.05 μg/(kg·min) and control group (midazolam 0.05 mg/kg).Heart rate (HR),mean arterial pressure (MAP),and pulse oxygen saturation (SpO2),respiratory rate (RR),SpO2 change,operation time,recovery time,the incidence of adverse reactions and the satisfactory rate of both patients and surgeons were monitored and recorded before the medication,3 min after the medication,at beginning of the surgery,during and immediately after the surgery,and 30 min after surgery.Results Two groups of patients had no obvious difference in intraoperative MAP,HR,RR,SpO2 and postoperative recovery time (P＞0.05);the incidence of postoperative nausea and vomiting in the test group was significantly higher than that in control group (P＜0.05); Patients and surgeons satisfaction in the test group was higher than that in control group (91.3±11.6)vs (52.7±10.4) (P＜0.05).Conclusions Midazolam combined with remifentanil for lower eyelid blephamoplasty has less inhibitory effect on circulatory and respiratory functions and the patients come round fast after surgery.But there are risks of respiratory inhibition in the induce phase and nausea and vomiting in the recovery stage.

ObjectiveTo explore the effect of motor on functional recovery of the lower limb in hemiplegic patients after cerebral infarction. Methods62 patients recovering from cerebral infarction were divided into the control group (30 cases) and motor imagery group (32 cases). All patients received routine treatment and a motor relearning program. Patients in the motor imagery group were given mental practice in activities of the lower limb. They were assessed with Fugl-Meyer Assessments (FMA) and Modified Barthel Index (MBI) before and after treatment. ResultsThe scores of FMA and MBI were improved in the motor imagery group compared with those in the control group (P<0.05) after treatment. ConclusionMotor imagery can facilitate the recovery of lower limb function in patients with hemiplegia.

BACKGROUND:Rehabilitation training equipments play an important role in the rehabilitation treatment. Because of poor muscle strength and joint mobility in patients, we must guarantee the safety of rehabilitation training equipments.
OBJECTIVE:To design a new suitable man-machine interface that ensures patients can use rehabilitation equipments and even parts of fitness equipments safely.
METHODS:Through user experience research, we found the flaws of the existing rehabilitation equipment. Depending on the principles of ergonomics, we designed a new man-machine interface for upper limb exercise through survey and computer-aided design.
RESULTS AND CONCLUSION:The new man-machine interface program achieves the rapid wear and discharge between patients and rehabilitation training equipment, and importantly, it can automatical y separate people from the equipment when the patient's body discomforts or equipment failure appears. What’s more, this man-machine interface can be promoted to other fitness equipments. As a result, rehabilitation training for patients wil be more convenient.

BACKGROUND:Digital three-dimensional model which can reflect the fine structure of the chambers inside heart not only enhances the understanding of cardiac physiology, but also provides basic medical data for the study of cardiac electrophysiology simulation and endocardial electrophysiological mapping navigation. OBJECTIVE:To construct the digital three-dimensional model of cardiac cavity from sectional data and in conformity with the actual anatomical structure. METHODS:Image segmentation was accomplished in MATLAB environment. Firstly, registration of human cardiac cavity slice dataset was realized. Secondly, classifying each composition was achieved by clustering method according to color characteristics of the image. Then, both cardiac cavity and related connected region was distinguished by region growing method. At last, the processed image was reconstructed through dedicated medical processing software into three-dimensional model of the cardiac cavity. RESULTS AND CONCLUSION:The proposed method could reconstruct quite exquisite three-dimensional model of the cardiac cavity. In models, left and right atrial and ventricular structure was clear. Aorta and superior vena cava were visible. Three tricuspid and mitral valve were also observed. Results indicated that reconstructed model can reflect the anatomical characteristics of cardiac cavity accurately, and provide basic medical data for the study on electrophysiological simulation and endocardial electric mapping.

Objective To observe the effect of scalp acupuncture on cognitive and motor functions of stroke patients in recovery stage.Methods80 stroke patients with cognitive disorder were randomly divided into the scalp acupuncture group (n=41) and control group (n=39). All patients of two groups were treated with routine therapy and rehabilitation training, but the cases of the scalp acupuncture group were added with scalp acupuncture. The cognitive function, motor function and activities of daily living (ADL) of all patients were assessed by delitescence and amplitude of event-related potential (ERP) P300, Fugl-Meyer Assessment (FMA), Barthel Index (BI) respectively before and 3 months after treatment.ResultsAfter treatment, P300 delitescence of the patients in the scalp acupuncture group shorten to 38 ms in average while in the control group shorten only to 17 ms, the therapeutic effect of the scalp acupuncture group was superior to that of the control group ( P<0.05). The scores of FMA and BI of the patients in the scalp acupuncture group were also better than those in the control group ( P<0.05).ConclusionScalp acupuncture can efficiently improve the cognitive function of stroke patients in the recovery stage, and promote the recovery of motor function and ADL.

Objective:To study the relationship between the level of serum homocysteine (Hcy) and the antisense non coding gene (ANRIL) of long chain non coding RNA (lncRNA) cell cycle dependent kinase inhibitor 2B gene, and the effect on Atherosclerosis inflammation, that is, the expression of interleukin-10 (IL-10) and Monocyte chemoattractant protein-1 (MCP-1) in Human umbilical vein endothelial cell (HUVEC).Methods:HUVEC was cultured in vitro and cells were treated with different concentration gradients (blank control group, 0.5, 1.0, 2.0, 5.0 mmol/L) of Hcy. The expression level of lncRNA ANRIL was detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR). Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of MCP-1 and IL-10. LipoFilter transfection reagents were used to transfect shANRIL and shNC into different cells, respectively. In the above experiment, the optimal Hcy concentration (5.0 mmol/L) was selected for intervention for 24 hours. Western blot was used to detect the protein expression levels of MCP-1 and IL-10.Results:After 24 hours of intervention with different concentrations of Hcy in HUVEC, Hcy significantly damaged endothelial cells, and the higher the Hcy concentration, the more severe the cell damage. Compared with the blank control group, the Hcy intervention group showed an increase in lncRNA ANRIL and MCP-1, while IL-10 decreased (all P<0.05); As the concentration of Hcy intervention increases, IL-10 decreases, while lncRNA ANRIL and MCP-1 increased (all P<0.05). Compared with the blank control group, the Hcy group, the shNC+ Hcy group, and the shANRIL+ Hcy group had lower levels of IL-10 protein expression and higher levels of MCP-1 protein expression (all P<0.05). Compared with the shANRIL+ Hcy group, the Hcy group and the shNC+ Hcy group had lower levels of IL-10 protein expression and higher levels of MCP-1 protein expression (all P<0.05). There was no statistically significant difference in the expression levels of IL-10 protein and MCP-1 protein between the shNC+ Hcy group and the Hcy group (all P>0.05). Conclusions:Hcy upregulates MCP-1 expression and downregulates IL-10 expression by promoting lncRNA ANRIL expression. Thus, it can promote cellular inflammatory reaction and participate in Atherosclerosis.

Since the first operational definition of cognitive frailty was proposed by the expert consensus group of the International Academy of Nutrition and Aging and the International Association of Gerontology and Geriatrics in 2013, frailty and neurocognitive assessment has become the standard diagnostic tool.Since then, the reported prevalence in the literature for cognitive frailty in community-dwelling elderly people vary by dozens of times, as a result of different scales and diagnostic cut-off points, seriously affecting health decision-making.This article reviewed the current literature with a focus on the re-recognition of the clinical significance of cognitive frailty, the limitations of existing assessment tools for diagnosis, and possible solutions in the future.

Objective:To investigate the effects of tuina, treadmill running or both on the expression of factors related to gastrocnemius muscle proteins after acute muscle injury and to explore the mechanisms involved.Methods:Thirty adult male Sprague-Dawley rats were randomly divided into a control group, a natural recovery group, a tuina group, a treadmill running group and a combined treatment group, each of 6. An impactor was used to induce an acute skeletal muscle injury in the right hind legs of all of the rats except those of the control group. One day after the successful modelling, the tuina, treadmill running and combined groups were given interventions as their name implied, 5 times a week for 3 weeks. The gait of rats in each group was analyzed and the number of times the rats fell into and striken by the electrical grid was counted. The injured muscles′ cross-sectional areas (CSAs) and the diameters of muscle fibers were observed using hematoxylin and eosin staining. The expression of mTOR, p-mTOR, p70S6K, p-p70S6K and smad2/3 protein were tested using western blotting. The relative expression of myostatin (MSTN) mRNA was measured using real-time quantitative polymerase chain reactions.Results:Compared with the natural recovery group, all the other groups fell into the electrical grid significantly less often. The average CSA and wet weight of the affected gastrocnemius had increased significantly in the tuina, treadmill running and combined treatment groups, with the average CSA increases in the treadmill running and combined treatment groups significantly greater compared with the tuina group. The average relative expression of mTOR, p-mTOR, p70S6K, and p-p70S6K in the other four groups increased significantly compared with the control group, while that of Smad2/3 and MSTN decreased significantly. Compared with the natural recovery group, the average increases in the other groups were significantly greater. Compared with the tuina group, the treadmill running and combined treatment groups showed significantly better improvements, on average.Conclusions:Tuina, treadmill running and their combination all can improve recovery from skeletal muscle trauma, at least in rats. However, treadmill running and combined treatment are more effect than tuina alone.

PEP06 is a novel endostatin-Arg-Gly-Asp-Arg-Gly-Asp(RGDRGD)30-amino-acid polypeptide featuring a terminally fused RGDRGD hexapeptide at the N terminus.The active endostatin fragment of PEPO6 directly targets tumor cells and exerts an antitumoral effect.However,little is known about the kinetics and degradation products of PEP06 in vitro or in vivo.In this study,we investigated the in vitro metabolic stability of PEP06 after it was incubated with living cells obtained from animals of different species;we further identified the degradation characteristics of its cleavage products.PEP06 underwent rapid enzymatic degradation in multiple types of living cells,and the liver,kidney,and blood play important roles in the metabolism and clearance of the peptides resulting from the molecular degradation of PEP06.We identified metabolites of PEP06 using full-scan mass spectrometry(MS)and tandem MS(MS2),wherein 43 metabolites were characterized and identified as the degradation metabolites from the parent peptide,formed by successive losses of amino acids.The metabolites were C and N terminal truncated products of PEP06.The structures of 11 metabolites(M6,M7,M16,M17,M21,M25,M33,M34,M39,M40,and M42)were further confirmed by comparing the retention times of similar full MS spectrum and MS2 spectrum information with reference standards for the synthesized metabolites.We have demonstrated the metabolic stability of PEP06 in vitro and identified a series of potentially bioactive downstream metabolites of PEP06,which can support further drug research.
