Objective To observe clinical application of the apparent Shikani laryngoscope in difficult airway, so as to provide reference for basic-level hospitals to deal with difficult airway. Methods 50 patients with difficult airway were randomly divided into 2 groups:Shikani laryngoscope group (S) that direct laryngoscope group (M) . After conventional induction, patients in two groups were given endotracheal intubation with different intubation tools by the same anesthesiologist, then the intubation time and the one-time success rate of intubation were compared between two groups. The hemodynamics of patients, were observed in two groups,the HR,SBP,DBP and SPO2 at before (T0),during (T1),2 min after (T2) and 5 min after intubation (T3) were recorded. The complications including gingival and oral mucosa bleeding, sore throat, hoarseness were also recorded in two groups.Results During the process of intubation, the hemodynamic changes of patients had statistically significant difference between T0 and T1, T2,T3 subgroups ( <0.05),T2 and T3 subgroups ( <0.05) . The intubation had less influence on hemodynamics of patients in group S than M group,but the SPO2 and T0 had no significant difference between two groups ( >0.05) .Comared with M group,the one-time success rate of intubation was higher,and the intubation time was shorter in S group and there were significant differences ( <0.05) . There was no significant difference in the intubation complications between the two groups ( > 0.05), and this may be associated with small sample cases. Conclusion Compared with ordinary laryngoscope, Shikani laryngoscope has incomparable advantages in handling difficult airway and is convenient to apply,so it is worth popularizing in basic-level hospitals.

Objective: To investigate the clinical significance of low-dose CT (LDCT) in coal mine workers with relatively long working years. Methods: A total of 907 coal mine workers with ≥20 working years were enrolled, among whom there were 863 male and 44 female workers with a mean age of 49.5 years. Digital radiography (DR) was performed for these workers in 2013, and LDCT was performed for three consecutive years from 2014 to 2016. Results: A total of 32 workers were found to have lung nodules by DR in 2013, while in 2014, 269 workers were found to have non-calcified lung nodules by LDCT, and there was a significant difference in the number of workers with lung nodules (χ²=233.73, P<0.005) . There was also a significant difference in the detection rate of nodules between the workers with different working years of dust exposure (χ²=6.648, P=0.00) . The male workers had a significantly higher detection rate of nodules than the female workers (χ²=5.690, P=0.017) . There was no significant difference in the number of nodules between workers with different types of work (χ²=16.985, P=0.05) . There were 443 lung nodules in total, among which 71.56% were solid nodules and 55.75% had a size of ≤4mm; malignant nodules were confirmed by surgery in 6 (0.66%) of the 907 workers after baseline LDCT. LDCT reexamination in 2015 and 2016 found new nodules in 8 workers and enlarged nodules in 3 workers, and there was no significant change in the number of nodules with a size of ≤4 mm. Conclusions It is necessary to perform high-risk population screening for coal mine workers by LDCT. The follow-up strategies for nodules with a size of ≤4mm are the same as those for negative results; annual reexamination is recommended for nodules with a size of >4-8 mm, and clinical treatment should be considered for nodules with a size of >8 mm.
