Journal of Forensic Medicine 2015;31(5):359-365
OBJECTIVE:
To analyze palm ratio of body surface area (BSA) based on the body different surface area formula.
METHODS:
Forty-four Chinese adult males were selected in this study. The contour of left single palm was recorded and the palm area was calculated by cut-paper weighing method. The body surface was calculated by the height and weight based on 12 formulas of body surface area. Then, the palm ratio of BSA was calculated.
RESULTS:
The average palm ratio of BSA was (0.789 ± 0.075)%. The data showed statistically significant difference compared with the traditional ratio (1%) (P < 0.05).
CONCLUSION
The ratio of BSA in Chinese adult male population showed more accuracy compared with the traditional ratio in this present study. The forensic evaluation can be affected by using the different ratio of BSA.

Objective: This study was undertaken to explore the effect of left ventricular assist device (LVAD) on failing heart after myocardial ischemia. By detecting the changes of plasma atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and cardiac troponin I (cTnI) levels within 6 hours after the implantation of LVAD, we review the basis on which neurohormones may be used to determine prognoses of failing heart and choose an optimal predictor. Methods: 15 adult healthy dogs were divided into 3 groups randomly. The LVAD was implanted in LA-AO bypass in all three groups. Myocardial ischemia was induced by ligating the main left anterior descending coronary artery (LAD). In group A, after a ligation of 10 minutes, the myocardium was reperfused for 6 hours. In group B, after a ligation of 40 minutes, the myocardium was reperfused for 6 hours. In group C, after a ligation of 40 minutes, the LVAD was used for LV support for 6 hours. Results: After 6 hours reperfusion,in group C, the hemodynamics was significantly improved, the ANP, BNP and cTnI were return to normal level, and myocardial ultrastructure was recovered significantly. While in group B, the hemodynamic, the neurohormones, and myocardial ultrastructure were worse. Relational analysis demonstrated that ANP and cTnI levels were influenced by hemodynamics obviously, but there was a weak relationship between circulating BNP and hemodynamics. Plasma BNP level was able to identify the cardiac function status. Conclusion: LVAD can be beneficial to improve cardiac function and can reduce the plasma levels of ANP, BNP and cTnI. Plasma BNP level can identify the cardiac function status. Those findings indicated that plasma BNP determination provides important prognostic information about cardiac function and may be a better prognostic indicator.

Objective To investigate whether functional electrical stimulation (FES) can improve the expression of proteins in the NMDAR1-pGLuR1 pathway so as to promote the recovery of motor function and sensation after stroke.Methods Eighty-one Wistar rats were used to make a photochemical brain model of local ischemia.Rats were randomly assigned into a sham, placebo stimulation or FES group.Rats in the placebo and FES groups had local ischemia induced in the M1 zone of the brain using the photosensitive dye Bengal rose.It was administered intravenously and a laser beam was then stereotactically positioned on the skull.The rats in the FES groups were stimulated for 30 minutes (10 minutes on, 10 minutes off, then 10 minutes on).The placebo group's treatment was similar, but without the electric current.The rats in the sham group received no intervention.The cylinder test and the adhesive-removal test were used to test the rats' motor function and sensation before the operation and before they were sacrificed.Cohorts were sacrificed after 3, 7 and 14 days of intervention.NMDA receptor and AMPA receptor were detected in the peri-ischemic cortex using western blotting.Results After 7 and 14 days the index of forelimb motor function in the cylinder test of the FES group was significantly better than that of the placebo group.The average adhesive-removal time of the FES group was also significantly faster compared with the placebo group.After 7 days the average expression of NMDAR1 in the FES group was significantly higher than in the placebo group.The average expression of GluR1 and pGluR1 in the FES group was significantly higher than in the placebo group after 14 days.Conclusion Functional electrical stimulation can improve motor function after ischemia through the NMDARAMPAR signal pathway, at least in rats.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease. The prevalence of NAFLD is increasing year by year in the world, which seriously threaten the public health. The pathogenesis of NAFLD is complex, and there is no specific treatment for NAFLD. Natural-derived compounds have the characteristics of multi-target and multi-mechanism, which can improve the curative effect and reduce the toxic and side effects by regulating multiple factors of the disease. They are ideal drugs for treating complex diseases and have unique advantages in improving NAFLD. However, low intestinal absorption, poor bioavailability, and single medicine efficiency limit the utilization of many compounds, and further drug development and clinical application are challenging. This paper reviews the research progress of natural-derived compounds in the prevention and treatment of NAFLD in recent years, analyzes the existing problems, and discusses the improvement strategies, so as to provide reference for related research.

BACKGROUND:Previous studies have found that platelet-rich fibrin has a good ability to induce gingival soft tissue repair and regeneration.
OBJECTIVE:To observe the effects of platelet-rich fibrinversus colagen membrane on gingival soft tissue healing, and to evaluate the ability of platelet-rich fibrin to repair gingival defects.
METHODS:Twenty-two patients (2 premolar teeth and 20 molars) scheduled for premolar or molar removal or ridge preservation due to various reasons were selected and randomized into two groups. Bio-Oss was implanted into the extraction socket folowed by covering with platelet-rich fibrin or colagen membrane. Healing time and healing rate of gingival defects were detected to evaluate the ability of platelet-rich fibrin to promote gingival tissue healing at 1-2 weeks after Bio-Oss implantation.
RESULTS AND CONCLUSION:The healing time was (12.17±2.25) days in the platelet-rich fibrin group and (17.30±2.58) days in the colagen group. The healing rate of the platelet-rich fibrin group was notably higher than that in the colagen membrane group at 1 and 2 weeks after Bio-Oss implantation. These findings indicate that platelet-rich fibrin is better than colagen membrane to improve the healing of gingival soft tissues with a shorter healing time.

BACKGROUND: In clinical, the research on the method and the material of the soft tissue defect of the operation area has been in depth. It wil have a positive impact on our exploration and research in this field through the establishment of reliable experimental animal oral soft tissue defect model. OBJECTIVE: To establish a rabbit model of oral soft tissue defects for oral treatment of soft tissue defects in-depth study. METHODS: Eighteen 3-month-old male New Zealand rabbits were enrol ed. A tissue ring cutting dril of 5 mm diameter was used to prepare round ful -thickness soft tissue defects in the front part of the hard palate and, respectively, from the back of the maxil ary incisors, about 2 mm from the hard palate mucosal edge. Morphology and histology were observed at 3, 7, 14, 21, 28 and 56 days after model establishment. RESULTS AND CONCLUSION: (1) Morphological observation: After 3 and 7 days, the wound’s inflammatory reaction was obvious. As the time goes, the inflammatory response subsided, the wound gradual y healed. Scar formation was observed at 21, 28 and 56 days after surgery. (2) Histological observation: 3 and 7 days after injury, many inflammatory cel s were infiltrating, and tissue necrosis area was larger. At 7 days after surgery, with the extensive formation of connective tissue proliferation and new blood capil aries, the wound gradual y shaping completely. (3) Results indicated that a rabbit model of oral soft tissue defects was successful y established, which was in line with the physical laws of wound healing and the characteristics of human oral soft tissue defects healing.
