ABSTRACT
This article recorded the analysis and comparison between the medicinal nature theory of traditional Chinese medicine(TCM) and ethnomedicine(EM). The vocabulary of "medicinal nature" was suggested to indicate the properties of ethnomedicine. Based on the influence of TCM medicinal nature theory on EM in China, the application of medicinal nature theory in EM was divided into 3 classes, and the standardizing principles for EM medicinal nature were proposed. It was suggested that medicinal quality, flavor, tendency, tropism, degree and efficiency can be used for the classification standard for EM medicinal nature.
ABSTRACT
<p><b>OBJECTIVE</b>To assess the impact of early enteral nutrition (EN) on the intestinal motility of patients after esophagectomy.</p><p><b>METHODS</b>Thirty-five consecutive patients undergoing esophagectomy for esophageal cancer by a single surgical team from the Peking University Cancer Hospital from June 2011 to July 2011 were enrolled. Patients were randomly divided into EN group (n=20) and parenteral nutrition group (control group, n=15) within 24 h after esophagectomy procedure. Bowel sound recovery time was monitored by auscultation, and the gastrointestinal tract symptoms were recorded.</p><p><b>RESULTS</b>Bowel sound recovery time was (45.1±20.3) h in the EN group, and was (56.7±17.0) h in the control group (P=0.082). Gastrointestinal symptoms such as nausea, abdominal distension, diarrhea occurred in 4 patients in EN group and 3 patients in control group and were alleviated by lowering infusion speed and more off-bed ambulation, and no significant difference was seen between the two groups (P=1.000).</p><p><b>CONCLUSIONS</b>Early enteral nutrition in the patients after esophagectomy is safe and feasible. Early enteral nutrition does not delayed bowel function recovery or increase gastrointestinal symptoms.</p>

<p><b>OBJECTIVE</b>To establish an animal model to replicate the blunt impact brain injury in forensic medicine.</p><p><b>METHODS</b>Twenty-four New Zealand white rabbits were randomly divided into control group (n equal to 4), minor injury group (n equal to 10) and severe injury group (n equal to 10). Based on the BIM-II Horizontal Bio-impact Machine, self-designed iron bar was used to produce blunt brain injury. Two rabbits from each injury group were randomly selected to monitor the change of intracranial pressure (ICP) during the impacting process by pressure microsensors. Six hours after injury, all the rabbits were dissected to observe the injury morphology and underwent routine pathological examination.</p><p><b>RESULTS</b>Varying degrees of nervous system positive signs were observed in all the injured rabbits. Within 6 hours, the mortality rate was 1/10 in the minor injury group and 6/10 in the severe injury group. Morphological changes consisted of different levels of scalp hematoma, skull fracture, epidural hematoma, subdural hematoma, subarachnoid hemo- rrhage and brain injury. At the moment of hitting, the ICP was greater in severe injury group than in mild injury group; and within the same group, the impact side showed positive pressure while the opposite side showed negative pressure.</p><p><b>CONCLUSIONS</b>Under the rigidly-controlled experimental condition, this animal model has a good reproducibility and stable results. Meanwhile, it is able to simulate the morphology of iron strike-induced injury, thus can be used to study the mechanism of blunt head injury in forensic medicine.</p>
