Objective In order to improve the teaching effectiveness of anatomy in nursing, this article made an exploration on the experimental teaching reform combined with the characteristics of nursing profession. Methods The nursing students of class 1and 2 of 2013were set as the research object. The class 1 (110) as experimental class, class 2 (110) for the control group. In the experimental class, the reform of teaching method and teaching quality was improved by adjusting the teaching syl-labus and teaching contents. The control class used the traditional experimental teaching method. The experiment class' teaching reform research of the human anatomy carried on the 1 semester. Exam achievement evaluation and the questionnaire survey were adopted to assess the teaching effect. SPSS 13.0 software was used to do statistical analysis and t test was used to compare two groups of students test scores, experiment grades, test scores and total scores. Results Experimental theory examination results [(47.80±7.30) vs. (44.85±8.38)], experiment grades [(15.48±1.76) vs. (14.55±2.19)], ex-periment test scores [(15.52±2.22) vs. (14.35±2.64)], total score [(78.80±8.99) vs. (73.75±10.53)] were better than control group (P<0.05). In questionnaire survey,more than 80% of the students think that the reformed teaching method can help to improve the teaching effect. Conclusion In human anatomy experiment teaching reform, the reformed experiment teaching method can significantly improve students' scores and the teaching effect. It is better than the traditional method, and is worth publicizing.

In-stent restenosis after stenting is a major problem to perplex the minimally invasive interventional treatment and development in atherosclerotic cardio-cerebrovascular diseases.Intravascular inflammatory response is one of the important causes for restenosis after stenting in which as represented by interleukins,the cytokines play complex and variable roles.This article reviews the effects of the expression levels of interleukins on vascular endothelial hyperplasia and the incidence of in-stent restenosis.

OBJECTIVE: To summarize the clinical features of epistaxis in the posterior fornix of inferior meatus and its comprehensive treatment measures. METHOD: We collected and retrospectively analyzed the clinical data of 212 cases of epistaxis hospitalized in our department, among which 23 cases were diagnosed as epistaxis in the posterior fornix of inferior meatus. They underwent nasal endoscopic exploration and coagulation surgery with one case under general anesthesia and the other 22 under local anesthesia. The bleeding from olfactory cleft, spheno-ethmoidal recess and the middle nasal meatus were excluded for all the patients during the surgery. After shifting the inferior turbinate inward by fracture, the active bleeding was found in the posterior fornix of inferior meatus, which was stopped immediately by bipolar coagulation. The areas of coagulation and nasal mucosa erosion were packed with nasopore after operation. RESULT: For all the patients, bleeding spots were definitely located during the operation and successfully coagulated. None of them suffered from recurrent-bleeding within 1 week postoperatively. Followed up for 6 to 12 months, there was no epstaxis recurrence or nasal cavity adhesion at the bled side in all patients. CONCLUSION For intractable epistaxis patient, after excluding the bleeding in olfactory cleft, sphenoethmoidal recess and the middle nasal meatus, it should be considered that the bleeding might come from posterior fornix of inferior meatus. It is the key point to thoroughly expose the posterior fornix of inferior meatus by shifting the inferior turbinate inward by fracture and explore for the bleeding spot carefully.

Objective To investigate the clinical efficiency of repairing ankle and calf wounds by antegrade or retrograde perforating flap of posterior tibial artery. Methods 13 cases with skin defects of ankle and calf wounds were reviewd. The defects were repaired using antegrade or retrograde perforating flap of posterior tibial artery from January 2011 to February 2013, 8 males and 5 females; aged 19 to 65 years old. Wounds were located in the ankle and calf, area which the tibial artery support contu-sioned slightly;defects were associated with exposed bone or tendon, exposed blood vessels. Of the 13 cases, 5 cases have multiple ankle fracture with blood circulation disorders, internal and external fracture fixation were performed emergency with blood ves-sels and nerves exposed, at the same time emergency line wound repair by posterior tibial artery perforating flap. The other 8 cases have no blood vessels and nerves exposure, and accepted vacuum sealing drainage emergency external fixation and flap surgery. Seven cases accepted V-Y antegrade perforating flap of posterior tibial artery, 6 cases using retrograde tibial artery perforator flap. Whose defects were ranged from 1.5 cm×2.0 cm to 9.0 cm×5.0 cm. Antegrade or retrograde perforating flap of posterior tibial ar-tery with 1.5 cm×3.0 cm to 14.0 cm×7.0 cm was used to repair ankle or lower leg medial defect. Antegrade flap donor site sutured directly, but retrograde flap donor site take full thickness skin graft repair from abdomen. Results Circulations of the all 13 cases were stable, with wound healing well after 2 weeks. The patients were followed up for 6 months to 24 months, average of 13 months. All flap graft survived, pedicle no bloated andcat eardeformity. Flaps were soft, no bloated appearance;color was con-sistent with normal skin. Fracture line in the 5 patients was disappeared. Bone healing time was 3.0 to 4.0 months. At the direct su-ture skin donor sites, postoperative scar was small;skin graft donor sites had no obvious scar. Postoperative ankle dorsiflexion 10° to 25°, plantar flexion 15° to 45°. Patients were extremely satisfied with the results of repair. Conclusion Using antegrade or ret-rograde posterior tibial artery perforator flap without sacrificing the main vessel, it is a simple and effective method to repair the medial malleolus and calf wounds.

In recent years, here are many new understandings in the definition, etiology, diagnosis and treatment of transient ischemic attack (TLA).The latest viewpoint considers that TIA is a transient episode of neurological dysfunction caused by brain, spinal cord or focal retinal ischemia, without the evidence of acute infarction. The duration of TIA is no longer the key factor, whether the existence of infarction or not is the key factor in the differentiation of TIA and ischemic stroke. Therefore ,it should emphasize the importance of neuroimaging in the diagnosis of TIA. As a neurological emergency, the risk level of TIA should be stratified and evaluated, and the active interventions should be performed.

The article introduces the advances in the evaluation of transient ischemic stroke (TLA) and reviews them from four aspects, including identifying whether the symptoms accord with the diagnosis of TLA, which blood supply area the ischemia is located in, evaluating the pathogenesis of TIA, and predicting its prognosis.

Transient ischemic attack is an unstable cerehrovascular sign and a neurological emergency. The development of neuroimaging not only provides an important approach for insight into the understanding of transient ischemic attack, but also becomes one of the hotspots in the research of transient ischemic attack.

Objective To investigate the effect of orphan nuclear receptor NR4A1 expression on oxygenglucose deprivation (OGD)-induced apoptosis in cultured rat cerebellar granule neurons and its possible mechanisms.Methods Primary rat cerebellar granule neurons were cultured for 7 to 8 days,and then treated with OGD.The activity of cultured rat cerebellar granule neurons was assessed by methyl thiazolyl tetrazolium (MTT) assay,apoptosis was detected with flow cytometry,the expressions of NR4A1,caspase-3 and cytochrome c were determined by Western blot analysis,NR4A1 mRNA expression was detected with real-time polymerase chain reaction.The rat cerebellar granule neurons were transfected with lentiviral vector-encoding rat NR4A1.The apoptotic rates and expressions of caspase-3 and cytochrome c in rat cerebellar granule neurons transfected with NR4A1 were detected after OGD.Results The activity of rat cerebellar granule neurons decreased significantly,the apoptotic rate increased significantly,the expressions of NR4A1 mRNA and protein as well as caspase-3 and cytochrome c incrased significantly along with the OGD time.NR4A1 was overexpressed,apoptosis rate was significantly reduced in rat cerebellar granule neurons transfected with NR4A1.The expressions of caspase-3 and cytochrome c were significantly reduced in the rat cerebellar granule neurons transfected with NR4A1 after OGD.Conclusions NR4A1 overexpression may reduce OGD-induced apoptosis in rat cerebellar granule neurons by downregulating the expressions of caspase-3 and cytochrome c.
