Modern Clinical Nursing 2016;15(7):34-37
Objective To investigate the status and correlation between fatigue and health locus of control in patients with chronic obstructive pulmonary disease ( COPD ) . Method The multidimensional fatigue symptom inventory-short form and health locus of control questionnaire were used to investigate the fatigue and health locus of control among 150 COPD patients. Results The score on fatigue was 78.82 ± 1.50, in the middle-high level. The two factors scored the higher were physical fatigue and activity. The total score on health locus of control was 61.76 ± 5.02, at a middle-low level. The dimensions of health locus of control, ranked in a descending way in scores, included external control by destiny and authorities and internal control. The scores on external control by destiny and authorities were positively related that of total score on fatigue (P<0.05 for both) and the score of internal control was negatively correlated (P<0.05). Conclusion The fatigue of COPD patients was at high level and the health locus of control was at middle level. In the clinical practice, nurses should pay attention to the enhancement of patients′health locus of control to help them take up health behaviors for the purpose of lowering their fatigue.

Objective To evaluate the value of imaging examination and diagnosis of airway foreign body in children. Methods 218 of airway foreign bodies confirmed by bronchoscopy were retrospectively analyzed in terms of clinical and imaging data. Results 218 patients included 140 males and 78 females. Their ages ranged 6 months to 12 years(mean,19.2 months). All patients had conventional radiographs on frontal chest films,neck lateral films and fluoroscopy. 34 cases underwent 64-slice spiral chest CT examination. According to the location of the foreign bodies,29 cases were in throat and subglottic,55 cases in trachea and 134 cases in bronchus(79 cas-es in the right,55 cases in the left). According to the character of the foreign bodies,5 cases were metal,29 cas-es in bone,93 cases in peanuts,59 cases in seeds,22 cases in fruits and vegetables and 10 cases in others respec-tively. Thirty-fourcases showed a direct sign of the foreign body and 177 cases showed the indirect signs. 34 cases on CT examination directly were showed foreign body in the tracheal bronchi. The diagnostic accuracy of CT exami-nation was 100%. Conclusions X-ray photograph and fluoroscopy were the first choice for aspiratory foreign bod-ies in children. CT examination is an important supplementary method when conventional X-ray examination is neg-ative.

Purpose To explore the correlation between fetal cardiac function and interventricular septal thickness in fetuses of gestational diabetes mellitus (GDM) mothers. Materials and Methods Thirty-nine GDM mothers were involved in the study and divided into group MH (fetuses of GDM mothers with interventricular septal hypertrophy) and group NMH (fetuses of GDM mothers with normal interventricular septal thickness). Ultrasonic cardiogram was performed for both groups to assess such variables as interventricular septum thickness at end diastole (IVSd), left ventricular ejection fraction (LVEF), left ventricular fraction shortening (LVFS), right ventricular fraction shortening (RVFS), the ratio of E and A of mitral flow (E/AMV), the ratio of E and A of tricuspid flow (E/ATV), peak velocity of aortic valve (VPAO), peak velocity of pulmonary valve (VPPA) and myocardial performance index (MPI). The results were further compared with those of control group. Results The VPAO, VPPA, LVEF and LVFS in group NMH were significantly higher than those in control group (P<0.05). The VPAO, VPPA, LVEF, LVFS and RVFS in group MH were significantly higher than those in control group whilst the E/AMV and E/ATV significantly lower than those in control group (P<0.05). The LVEF, LVFS and RVFS in group MH were significantly higher than those in group NMH whilst the E/AMV and E/ATV significantly lower (P<0.05). MPI in group MH was significantly higher than that in group NMH (P<0.05), whilst both were significantly higher than that in control group (P<0.05). The LVEF, LVFS, RVFS, VPAO and VPPA were positively correlated with IVSd (r=0.48, 0.51, 0.45, 0.30, 0.30;P<0.05). Conclusion Cardiac function in fetuses of GDM mothers may be associated with interventricular septal thickness.
