Objective To investigate the predictive value of trauma index on the prognosis in pa-tients with traumatic spinal cord injury.Methods Enrolled 168 cases of patients with traumatic spinal cord injury,the traumatic index score and the American Spinal Injury Association (ASIA)grade were as-sessed on admission,then followed up for 6 months,the Spearman correlation analysis was performed to a-nalysis the relationship between trauma index and ASIA grade,and Receiver operating curve (ROC)anal-ysis was used to evaluate the relationship between trauma index and prognosis.Results There was a sig-nificant negative correlation between trauma index score and ASIA grade(r =-0.68,P <0.01).A total of 157 cases (93.5%)completed follow-up,the trauma index score had a good predictive value on the traumatic death in these patients,it's sensitivity was 71.4%,specificity was 76.1%,the best cut-off point was 25 points(P <0.01 );Compared with the low score group (<25 points),the high group (≥25 points)showed a lower ASIA grade and higher mortality,the differences were statistically significant (P <0.01).Conclusion The trauma index score was related with the spinal cord injury,and it is a predictive factor of poor prognosis in patients with traumatic spinal cord injury.

OBJECTIVE:To investigate the cognition,evaluation and demands of medical staff to the clinical pharmacy work in the secondary and tertiary medical and health institutions in Xi’an city,and provide reference for further promoting the develop-ment of the local clinical pharmacy work. METHODS:20 secondary and tertiary medical and health institutions in Xi’an city were randomly selected to conduct a random sampling questionnaire for physicians,nurses (senior nurses),pharmacists (non-clinical pharmacist)and other medical technicians. And the results were statistically analyzed. RESULTS:Totally 1 020 questionnaires were sent out,851 were effectively received with effective recovery of 83.4%. 45.9% respondents knew clinical pharmacy,and“Col-league”was the main channel;34.3% thought clinical pharmacy“only maintained normal operation. 74.7% surveyed medical staff,92.6% surveyed pharmacists and 70.6% surveyed physicians thought clinical pharmacists“should”take round with the doc-tors and nurses;44.3% respondents showed“dissatisfaction”and“general satisfaction”with the clinical pharmacy work in their hospitals. 48.5% respondents would take the initiative to consult the clinical pharmacist for medication;45.5% respondents partial-ly accepted the drug information provided by clinical pharmacists. There were significant differences in the investigation results in aspects of respondents’understanding level and channel for clinical pharmacy,cognition for development situation of clinical phar-macy,evaluation for clinical pharmacists participating round,demand for consulting the medication,acceptance for drug informa-tion provided by clinical pharmacists,and other items(P<0.05). CONCLUSIONS:The cognition and effect of clinical pharmacy work on medical staff need to be further strengthened,clinical pharmacists should also have solid clinical knowledge and the knowl-edge of medicine to meet the demand of medical staff in different positions,the acceptance of medical staff to the pharmaceutical care needs to be further improved. Clinical pharmacists should earnestly fulfill their job functions through various efforts to promote rational drug use.

Objective To evaluate the clinical efficacy of the application of auricular composite tissue flap in treatment of nasal alar de-fect. Methods 43 cases of nasal defects patients were admitted to our hospital from January 2008 to March 2013, 23 cases of them were treated with auricular composite tissue flap transplantation, and the other 20 cases were given nasolabial sulcus flap transfer operation. All patients were followed-up for 6 to 12 months, and the rate of secondary surgery, proliferation of scar, and flap survival of the two groups were compared. Results Treatment of auricular composite tissue flap transplantation has more advantages in terms of the rate of secondary surgery, proliferation of scar, and flap survival, and the difference is of statistical significance (P<0. 05). And there is no obvious differ-ence in satisfaction degree of cosmetic outcomes. Conclusion Auricular composite tissue flap surgery has the advantages of simple opera-tion, good appearance and good efficacy.

In order to solve the problem of poor communication, low efficiency of consultation, and even affecting self-confidence caused by unskilled skills and insufficient cooperation with patients in the real clinic, and to solve the problem during the clinical thinking training that beginners do not know how to organize effective information and complete the process of diagnosis and differential diagnosis more efficiently. By applying the artificial intelligence (AI) virtual patient (VP) system to the process of teaching diagnostic knowledge and clinical thinking training. It provides the students with the experience of simulating the diagnosis and treatment of the clinical real scene. Let the students talk with the VP system for inquiry training and then go to the clinic to give the real patients inquiry and by simulating the process of treating the real patients, let the students take the initiative to complete the collection of medical records and clinical decision-making under the simulated scene to train the clinical thinking. This can not only solve the shortcomings of the previous simulation teaching and clinical teaching, but also stimulate students' interest in learning. According to the results of the questionnaire, students have a high acceptance of VP system simulation teaching. Through the results of homework and assessment and evaluation, the teaching results are better than before, and this teaching method should be further popularized.

OBJECTIVETo investigate the correlation of morphological characteristics and failure modes of two types of glass-fiber posts luted with self-adhesive resin cement and etch-and-rinse adhesive system.

METHODSThirty-six intact single-rooted premolars were collected and removed the crown. After root canal therapy, teeth were randomly divided into 4 groups. Group A: Self-adhesive with POPO fiber post. Group B: Etch-and-rinse with POPO fiber posts. Group C: Self-adhesive with Para Post. Group D: Etch-and-rinse with Para Post. Each root was sectioned into six 1 mm-thick serial slices and a push-out test was performed. The dentin-cement-post adhesive interface of each specimen and failure modes after fracture were evaluated by stereomicroscope observation.

RESULTSInterface morphology observe indicated that voids present in group B (64.2%) and D (66.7%) were significantly higher than group A (5.8%) and C (13.7%) (P < 0.001). Interface gaps appeared at the resin-dentine interface in group D (41.2%) were significantly higher than group A (13.5%) and C (11.8%) (P < 0.0083), and the failure modes in each group were significantly different (P < 0.0083) except for group A and B (P = 0.69).

CONCLUSIONVoids present in cement layer were associated with the luting agent involved. Morphological characteristics of the fiber post-resin luting agent-root dentin adhesive interface were discrepant with failure modes in different root region. There were interaction between adhesive systems and fiber posts.

Previous studies have shown that paeonol can antagonize acute myocardial ischemia and infarction in rat. This study further researched the effects of paeonol on blood pressure and blood flow in the artery of spontaneously hypertensive rats and its mechanisms related on vasomotion. Firstly, thirty spontaneously hypertensive rats were randomly divided into spontaneously hypertensive control group and paeonol-treating groups of high dose and low dose, and also, the other ten Wistar rats as healthy control group. Before and after the intraduodenal administration of the drug, arterial blood pressure was measured by carotid artery and blood flow through the renal artery and carotid artery in vivo were measured by animal flowmeter. The same volume of solvent was given to the spontaneously hypertensive control group and the healthy control group, and the other operations were same. In order to further study the effect of paeonol on vasomotor function, the superior mesenteric artery, renal artery and coronary artery of the spontaneously hypertensive rat were removed and separated, precontracted by a certain concentration of potassium chloride (KCl) and 5-serotonin (5-HT) respectively, and dilatory responses were assessed by cumulative addition of paeonol. Results showed that after duodenal one-time delivery of paeonol, the blood pressure significantly lowered, the renal arterial blood flow and the carotid arterial blood flow significantly increased in spontaneously hypertensive rat. And also, paeonol relaxed the mesenteric artery, renal artery and the coronary artery of spontaneously hypertensive rat in a concentration-dependent manner. These results indicated that the effect of paeonol on decreasing arterial blood pressure and increasing the arterial blood flow was related to its vasodilative effect.
