Objective To explore the effect of seminar applied in instruction of Introduction of Nursing Science for advanced vocational nursing students.Methods A total of 246 advanced vocational nursing students admitted in 2013 from class 1 to class 5 were named as the control group,who received traditional teaching method.Meanwhile a total of 252 advanced vocational nursing students admitted in 2013 from class 6 to 10 were set as the experimental group,and were given seminar teaching.We adopted California Critical Thinking Dispositions Inventory Scale,Academic Self-efficacy Scale and an anonymous questionnaire for teaching satisfaction.Theoretical examination was used to be final evaluation.Results The scores of theoretical examination in the experimental group were higher than that of the control group.The scores of critical thinking ability and academic self-efficacy of the experimental group were higher than those of the control group,with a significant difference.The result of the anonymous questionnaire showed that the experimental group showed a higher satisfaction degree with seminar teaching method.Conclusions Seminar teaching method applied in Introduction of Nursing Science is feasible and effective,which is better than traditional method in improving critical thinking ability,academic self-efficacy and teaching satisfaction.

Objective:To establish a method for the uncertainty evaluation of the determination of benzoic acid. Methods: The content of benzoic acid was determined by acid-base titration. By constructed mathematics model, the source of the measurement uncer-tainty was analyzed, and the uncertainty components were quantized and combined. Results:The expanded uncertainty of benzoic acid was 0. 36% and the results were expressed as(99. 99 ± 0. 36%,k=2). Conclusion:The mathematics model is reasonable and relia-ble,and can be used in the uncertainty evaluation of content measurement of benzoic acid.

AIM:To analyze the clinical significance of axial length, diopter and retinal nerve fiber layer thickness in hyperopia children with anisometropia amblyopia. ·METHODS: From January 2015 to January 2017 in our hospital for treatment, 103 cases, all unilateral, were diagnosed as hyperopia anisometropia amblyopia. The eyes with amblyopia were as experimental group ( 103 eyes), another normal eye as control group (103 eyes). We took the detection with axial length, refraction, foveal thickness, corrected visual acuity, diopter and the average thickness of retinal nerve fiber layer. ·RESULTS: Differences in axial length and diopter and corrected visual acuity were statistically significant between the two groups (P<0. 05). The two groups had no significant difference in retinal nerve fiber layer thickness (P>0. 05). There was statistical significance difference on the foveal thickness (P<0. 05). There was a negative correction correlation between the visual acuity, axial length with foveal and peripapillary nerve fiber layer thickness, but no significant difference in correlation ( P>0. 05 ). The positive correlation between diopter with nerve fiber layer thickness of foveal and around the optic disc were no statistically significant difference (P>0. 05). ·CONCLUSION:Retinal thickness of the fovea in the eye with hyperopic anisometropia amblyopia were thicker than those in normal eyes;the nerve fiber layer of around the optic disc was not significantly different between the amblyopic eyes and contralateral eyes. The refraction and axial length had no significant correlation with optic nerve fiber layer and macular foveal thickness.

Dextrocardia is formed by the disruption of the normal left-right (L-R) asymmetry of the thoracoabdominal organs.Asymmetric expression of Nodal,Pitx2,Cited2 have affected L-R asymmetry of vertebrate significantly,and generated dextrocardia,mesocardia,ectopia cordis,heterotaxy and so on.Dextrocardia is often accompanied by congenital cardiac malformation.Therefore,it is so difficult to be treated that it has poor prognosis.This paper reveiws the molecular mechanism and it's regulation of dextrocardia for proceeding the genetic diagnosis and early intervention of dextrocardia sequentially in order to improve the survival rate and life quality of patients.

Objective To study the effect of juvenile non-incarcerated oblique inguinal hernia on the development of testis and spermatic cord.Methods The volume of the testis was measured with B-ultrasound in normal and patient children.All patients were surgically treated and the spermatic veins were examined during operation.The patients were followed up for measuring the testicle volume at 3 months,6 months and 6 ～ 12 months after operation.Results Testicle volume on healthy side was larger than the involved side in patient group (P ＜ 0.05).There were still obvious differences between the two sides after 6 months(P ＜ 0.05).No significant difference was found after 6 ～12 months (P ＞ 0.05).Conclusion Non-incarcerated oblique inguinal hernia has effected on the spermatic cord and testicles,which need timely treatment.

Training mechanism reform was introduced in Chinese universities recently.It is a very useful attempt in the field of graduate education,in line with the trend of the international practice of graduate education.The core content of this reform is to build the research leading tutorial system and projects oriented grant-in-aid program.The intention of this reform is to mobilize the enthusiasm of both the instructors and graduate students effectively,who play key roles in the reform.In this paper,the author analyze the the difficulties and problems encountered in building up the instructor finance grantin-aid program,such as the inadequacy of instructors,involvement in policymaking,thecommercializationtendency of the teacher-student relationship,and the intensifying imbalance among different disciplines.The autor also proposes some countermeasures as preliminary solution.

Objective To investigate the impact of the different mode of delivery on postpartum lactation.Methods 1 678 pregnant women in our hospital were divided into cesarean section group(798 cases) and natural delivery group(880 cases).Open milk after delivery,breast fullness,the number of neonatal sucking and post-natal self-assessment milk water were compared between the two groups of pregnant women,and the impact of the mode of delivery on postpartum lactation was analyzed.Results Whether or not began to lactation (721/77cases),and the time of labor to beginning to lactation [(33.45 ± 9.68) h],and whether or not having breast fullness feeling (512/286 cases),and the time of labor to breast fullness feeling[(57.12 ± 13.90) h] in cesarean section group had significant difference with those of spontaneus labor group [(845/35 cases),(30.12 ± 10.25) h,(690/190 cases),(52.98 ±15.09) h] (x2 =21.613,t =2.452,x2 =41.813,t =2.818,all P ＜ 0.05).There was no significant difference in selfrating milk score [(2.02 ± 0.45) points vs (2.45 ± 0.51) points],and newborn sucking times 4 ～ 6d postpartum [(5.21 ±1.21) times vs (5.89± 1.82)times](t =2.012,2.532,all P ＜0.05).Conclusion Efficiency of the breast-feeding was affected by the impact of the mode of delivery.Rationalized breastfeeding guidance was necessary to strengthen for pregnant women by cesarean section.
