Application of PWW teaching method in cardiopulmonary resuscitation training of standardized training residents / 中华医学教育探索杂志

To study the effect of practice while watching (PWW) teaching method in cardiopul-monary resuscitation training of standardized training residents. 196 standardized training residents were selected, and PWW teaching method was used to carry out cardiopulmonary resuscitation training and as-sessment. The results were significantly higher than that before the training, and the satisfaction rate of the residents to the PWW teaching method was 100%.PWW teaching method could improve the effect of stan-dardized training resident doctors in cardiopulmonary resuscitation,and increase the interest in learning.

The diagnostic value of VILIP-1 and NR2 peptide combined detection in the early ischemic stroke / 中华检验医学杂志

Objective To Investigate the concentration of VILIP-1 and NR2 peptide in the serum of patients with ischemic stroke , and to explore their clinic value in early diagnostic of ischemic stroke patients.Methods The levels of VILIP-1 and NR2 peptide were examined by ELISA ( enzyme linked immunosorbent assay ,ELISA) with suspicious TIA ( defined as a neurological deficit that resolved within 24 hours) or acute ischemic stroke patients ( within 72 hours of onset of symptoms ) 340 cases,102 healthy controls,98 patients with vascular risk factors and 35 patients with hemorrhagic stroke.Among all the groups , VILIP-1 and NR2 peptide level were analyzed using the nonparametric Wilcoxon test.Diagnostic performance were analyzed among the groups with the two biomarkers independently and combinedly .Results Serum levels of VILIP-1 and NR2 peptide in patients with ischemic stroke (IS) were 9.80 (1.90-14.22) μg/L, 14.40 (5.60-27.91) μg/L respectively,which was higher than that of the healthy control group [VILIP-1:0.02 (0.01-0.09),NR2:0.33 (0.02-1.15),χ2 were 5.61 and 9.54,P<0.001],the group with vascular risk factors [VILIP-1:0.03 (0.02-0.16),NR2:0.27 (0.01-1.54),χ2 were 6.74 and 10.62,P<0.001], the group of patients non-stoke [VILIP-1:0.04 (0.03-0.19),NR2:0.53 (0.45-1.21),χ2 were 3.78 and 7.63, P <0.001 ].The levels of VILIP-1 and NR2 peptide was significantly increased in IS patients presenting within 3 h of symptom onset.When differentiating IS from patients with hemorrhagic stroke ,NR2 had a AUC of 0.934,showing a strong distinguishing effectiveness.Differentiating IS from healthy controls , patients with vascular risk factors and non-stroke patients,the AUC of combination of VILIP-1 and NR2 was 0.974,which was higher than the AUC of either VILIP-1(0.849) or NR2(0.862) alone(P <0.05). Conclusions VILIP-1 and NR2 peptide are very sensitive and specific biomarkers to the early diagnosis of IS.The combination of VILIP-1 and NR2 peptide has higher value of clinical applications than one of them independently.

Application of case-based learning (CBL) combined with problem-based learning (PBL) in emergency teaching for foreign students / 中华医学教育探索杂志

Objective To study the effect of case-based learning(CBL) combined with problem-based learning (PBL) in emergency teaching for foreign students.Methods Totally 33 foreign students were selected in department of emergency,Xuanwu Hospital of Capital University of Medical Sciences and were randomly divided into the observation group (n =17) and control group (n =16).Students in observation group were taught by CBL combined with PBL while those in control group were taught by traditional teaching method.Theory examination,physical examination and Sirm4000 simulated cardiopulmonary resuscitation skill appraisal were given at the end of the internship and achievement differences were compared between 2 groups.Attitude on the teaching method was studied in observation group by questionnaire.SPSS 17.0 software was used for statistical analysis； measurement data were expressed as mean standard deviation ((x) ± s) ； independent sample t-test was applied for comparison between groups； P ＜ 0.05 stands for difference having statistical significances.Results Theory result was (83.5±7.9) in observation group and (76.6 ±8.7) in control group (P=0.012).Cardiopulmonary resuscitation skill score was (84.3 ± 10.1) in observation group and (75.6-± 11.3) in control group (P =0.013).100.0％ students thought that the teaching method could improve the ability of self-learning.Conclusions Teaching method of CBL combined with PBL can stimulate the students' interest in learning and improve students' achievement.

Characteristics and inspirations of medical assurance for martial arts events in Beijing Olympic Games / 中华医院管理杂志

Objective To probe into characteristics of medical assurance for medical service preparation, medical staff deployment and injury treatment/rescue for martial arts competitions in Beijing Olympic Games. Methods Collecting data of all injuries treated onsite of martial art venues and in clinics of such venues, for statistical analysis of the injury occasions, injury location, injury types and post-injury treatment. Results During the test games, injuries found in martial arts repertoire competitions account for 0. 92% of all athletes in the category, mostly waist and lower limbs injury; injuries found in sanshou competitions account for 12.4% of all athletes in the category, mostly blunt trauma on head/face, body, perineum and four limbs, along with skin lacerations and 16 heavily wounded transferred to hospitals for rescue. No injuries are found in official games of martial arts repertoire competitions; in sanshou competitions, injuries account for 5. 5% of all athletes of the category, without heavy injuries for hospital rescue. Conclusion Athletes tend to be exposed to greater risk of injury in sanshou than in repertoire competition, headcount of injuries and injury heaviness in test games are higher than official games, probability of injuries of athletes of middle level is higher than those of other levels. Medical staff of professional surgeons of multidisciplinary skills are recommended.

The changes and clinical significance of thyroid hormone levels in old patients with sepsis / 中国综合临床

Objective To investigate the changes of thyroid hormone levels and its relationship with prognosis in old patients with sepsis. Methods APACHE Ⅱ score and SIRS score were documented in 140 old patients with sepsis,who were divided into Multiorgan dysfunction syndrome (MODS) group and non MODS group. Results The levels of FT3 and FT4 descended obviously and APACHE Ⅱ score and SIRS score increased remarkably in old patients with severe sepsis(P <0.05 or P <0.01). The level of FT3 and FT4 in death group and MODS group was much lower than that in the survival group (P < 0.05). Conclusion Inflammatory resction and eytokines may effect the hypothalamic- pituitary-thyroid axis. The levels of thyroid hormone can reflect old patients with sepsis condition. The patients with severer conditions may have lower levels of thyroid hormone who will be more likely to died of MODS.

Cytochemical changes of effect of Sijunzitang on different types of muscle fiber after exercise / 吉林大学学报(医学版)

Objective To discuss the function of Sijunzitang on relieving the exhaustion fatigue of muscle.(Methods Thirty-two) mice were divided into Quiet group,Fatigue group,Nature recovery group and Sijunzitang group.The mice in last three groups swam in the pool for 50 min every day.During exercise 0.2 mL Sijunzitang was injected into each mouse in Sijunzitang group every day.And the same dosage of normal saline was injected into other groups.After exercise,all the mice were killed and taken as material immediately.The technique of cytochemistry and Type MPV2 microspectrophotometer were used to test quantitatively the chemical components of different types(Ⅰ type,Ⅱ_A type and Ⅱ_B type) of muscle fibers in the quadriceps of mice after exhaustion exercise.(Results After) exhaustion exercise the content of glycogen and the activity of SDH in the muscle fibers in Fatigue group reduced remarkably (P

Study on systemic inflammatory response syndrome score and APACHE Ⅱ score predicting outcome in severe patients of emergency department / 中国医师进修杂志

Objective To study effect and significance of systemic inflammatory response syndrome(SIRS) score and APACHE Ⅱ score in prognosis in severe patients of emergency department.Methods Data of 114 patients were collected at admission.SIRS score and APACHEⅡ score were calculated in 24 hours.To analyze mortality of patients in different score,to estimate dependability of them.Result With SIRS score increasing,mortality rate increased as well and patients with SIRS score ≥2 or APACHE Ⅱ score ≥25 had significantly higher mortality rate.Conclusions SIRS score is a simple,useful predictor of outcome in patients of emergency department.It can be used in clinical generally.
