Objective To find the plantar pressure readings which best indicate foot inversion during the stance phase of walking among hemiplegic stroke survivors.Methods Twenty-two hemiplegic stroke survivors who were able to walk without extra aid were recruited as the experimental group, while 17 healthy elderly men of similar age and body weight were selected as the control group.Those in both groups were asked to walk at their preferred speed over a Footscan device which measured medio-lateral pressure ratios, maximum plantar pressures and the contact areas of both feet.The Clinical Spasticity Index (CSI) was used to evaluate the affected feet.Results The average medial forefoot pressure of the affected side in the experimental group was significantly lower than that of the control group, but their average mesopodium and heel pressure was significantly higher.The average pressure applied by the great toe on the uninjured side in the experimental group was significantly smaller than that of the control group, but the average mesopodium and heel pressure of both feet among the hemiplegics were significantly higher than those of the control group.Among the experimental group, the average medial forefoot pressure of the affected foot was significantly greater than that of the healthy foot.The average contact area of the great toe on the affected side was significantly bigger than was observed in the control group.That of the medial forefoot was, however, significantly smaller than in the control group.There was no significant difference in the contact area between the healthy and affected feet in the experimental group, though the maxmium medio-lateral pressure ratios of their full feet and forefeet on the affected side were significantly lower than those in the healthy group.No significant differences in the maxmium medio-lateral pressure ratios of the heel were observed between the two groups, nor of the full feet, forefeet and heels of the affected and unaffected sides in the experimental group.The patients demonstrated consistently reduced joint mobility on both sides during the stance phase, coinciding with increased inversion.A significant negative correlation was found between the maxmium medio-lateral pressure ratios of the full foot and the maximum pressure of the lateral part of forefoot in the experimental group, but there was no significant correlation with contact area or CSI.Conclusions Plantar pressure data can be used to describe the amount of foot inversion in the stance phase of walking with hemiplegic patients after stroke.The maxmium medio-lateral pressure ratios can effectively reflect their foot inversion.

Objective To clarify the role of insulin resistance on spontaneous recanalization of infarct-relat-ed arteries in the early phase of acute ST-elevation myocardial infarction (STEMI) in patients with normal glucose tolerance. Methods 141 consecutive patients with normal glucose tolerance and acute STEMI were enrolled in our study. Subjects were divided into TIMI 0-1 group (n =91 ) and TIMI 2-3 group (n =50) by primary coronary angi-ngraphy (CAG). The Gemini score and 0-3-vessel disease score estimated the severity and extent of coronary artery disease (CAD). Metabolic parameters and homeostasis model assessment for insulin resistance (IRI) were deter-mined. Results Serum level of fasting insulin, IRI and Gemini score were higher in TIMI 0-1 group than in TIMI 2-3 group [ (11.52±6.22)mU/L vs (7.54±3.65)mU/l,(2.79±2.32) vs (1.73±1.26),(59.17±26.95) vs ( 38.46±22.74) ( P <0.01)]. IRI was positively associated with Gemini score (r=0.185,P <0.05 ). Multivariate Logistic regression analysis revealed that IRI was independent risk factor influencing spontaneous recanalization of in-farct-related urteries(OR=2.87,95% CI=1.09-7.57,P<0.05). Conclusion Insulin resistance is independent risk factor influencing spontaneous recanalizafion of infarct-related arteries in the early phase of acute STEMI in pa-tients with normal glucose tolerance.

The social and behavioral research in promoting human health and the impact on human social relations and structures has been confirmed .With the development of social and behavioral science , the importance of ethics review for the research is also increased .Despite its uniqueness , the basic principles of ethics in social and behavioral research are consistent with other biomedical studies .This paper introduces ethics review points of social and behavioral research from the research design , risk and benefits , informed consent , deception and debriefing , expedited review , exemption of ethics review, privacy and confidentiality .This paper also introduces the relevant experiences from Europe and America giving references for the domestic professionals .
