Objective To investigate the double-lumen endobronchial intubation-related anatomical factors of respiratory tract in adult patients through measurement of the parameters of glottis and left main bronchus using computed tomography(CT). Methods A total of 206 patients of both sexes, aged 20-80 yr, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, scheduled for elective surgery, were enrolled in this study.The cervical and thoracic CT images were evaluated.The anteroposterior glottic diame-ter(AP-GD), anteroposterior tracheal diameter(AP-TD), transverse tracheal diameter(Tr-TD), left and right main bronchus diameters(LBD and RBD)and length between glottis and carina(G-TL)were measured.Multiple linear regression analyses were performed to detect the correlations between obtained pa-rameters and between obtained parameters and height. Results AP-GD was(19±3)mm, AP-TD(20± 4)mm, Tr-TD(16.6±2.4)mm, LBD(12.3±2.0)mm, RBD(13.7±2.0)mm and G-TL(126± 11)mm.AP-GD, height, AP-TD and Tr-TD were moderately correlated with LBD(r was 0.522, 0.584, 0.648 and 0.606, respectively, P<0.05).AP-TD +Tr-TD+AP-GD+height served as the inde-pendent variable, the fitting curve was confirmed, and the results showed that AP-TD, Tr-TD and height were the affecting factors for LBD, and the degree of correlation with LBD was as follows from high to low:Tr-TD(b′=0.334), AP-TD(b′=0.323), height(b′=0.243). When AP-GD served as the independ-ent variable and curve fitting was performed, there was no significant difference(P>0.05). Conclusion Tr-TD and AP-GD should be considered besides double-lumen endobronchial intubation-related anatomical factors such as LBD and height in adult patients.

Objective:To bring to doctors' attention to the first time attack of epilepsy in the patients with Parkinson' s disease, enhance the rational drug use and reduce the occurrence of adverse reactions in clinics. Methods: A Parkinson patient with the first time attack of epilepsy was synthetically analyzed on the mechanism of disease, therapy regimen and pharmaceutical care. Results:It was difficult to distinguish the symptom of epilepsy during the treatment of Parkinson' s disease from that of L-dopa induced dyskinesia, therefore, the suitable treatment was difficult to perform. Moreover, antiepileptic drug valproic acid could aggravate Parkinson syn-drome imperceptibly, which was easy to be ignored in clinics. Conclusion:L-dopa induced dyskinesia should try to avoid during the treatment of Parkinson, and should distinguish from the first time attack of epilepsy in order to choose proper antiepileptic drugs.

Objective To explore the relations between pulse pressure and LDL-C for elderly patients with hyperten-sion. Methods A total of 451 elderly patients with hypertension were selected and divided into four groups. Group A was 65 to 69 years of age, group B was 70 to74 years of age, group C was 75 to 79 years of age, and group D was ≥80 years of age. They were also divided into four groups according to PP levels: PP1 group ≤40 mm Hg, PP2 group 41 to 60 mm Hg, PP3 group 61 to 80 mm Hg, and PP4 group>80 mm Hg. They were divided into LDL-C group 1 (≥2.6 mmol/L) and LDL-C group 2 (<2.6 mmol/L) according to their LDL-C levels. Distribution of different age groups in four PP groups and the effects of different levels of LDL-C on pulse pressure were analyzed. Results (1) The propor-tions of PP2 group among the four age groups were 59.41%, 48.84%, 55.45% and 51.67%. The proportions of PP4 a-mong the four age groups were 4.95%, 3.88%, 3.96% and 7.50%. (2) Compared with PP1 group, the proportion of LDL-C ≥2.6 mmol/L in PP2 group, PP3 group and PP4 group was significantly increased. Conclusion (1) PP levels in different ages groups are concentrated on 41-60 mmHg. Among elderly patients with hypertension>80 mmHg, the pro-portion of patients with advanced age (≥years of age) is relatively higher. (2) LDL-C is the risk factor of increased pulse pressure for elderly patients with hypertension.
