Objective: To explore the characteristics of medical emergency disease spectra in Emergency Department of Haikou, China;and to provide clinical data for emergent disease treatment as well as emergency department personnel and equipment management. Methods: A total of 11870 patients (over 16 years old) who visited Emergency Departments of the First Affiliated Hospital of Hainan Medical University, Haikou city from January 1, 2015, through December 31, 2015 were selected. Data on patients' age, sex, diagnosis, treatment duration, and treatment month were analyzed with Microsoft Excel. Results: Peak treatment times were from 18:00 to 24:00. The top four diseases were involved with respiratory, digestive, nervous, and cardiovascular systems, respectively. Respiratory problems peaked from November to February and digestive problems peaked from February to August. Temperatures ranging from >22.5 ℃to 26 ℃ and high humidity exacerbated respiratory and digestive system diseases. Conclusion:The frequency of specific diseases that require emergency room care are affected by the local climate of Hainan Province.

Objective:To determine whether endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can rapidly distinguish among lung cancer,tuberculosis and sarcodosis,and to explore its sensitivity and specificity.Methods:Clinical data of patients with enlarged mediastinal or hilar lymphadenopathy who underwent EBUS-TBNA at our hospital between September 1,2012 and June 30,2015 for were retrospectively analyzed.The sensitivity,specificity,positive predictive value,and negative predicted value [including 95% confidence interval (CI)] were calculated..Results:A total of 299 lymph nodes from 201 patients underwent EBUS-TBNA were selected and no serious complications occurred.EBUS-TBNA showed a sensitivity of 87.9% (124/141) (95% CI:81%-92%),a specificity of 100.0% (124/124) (95% CI:97%-100%),and a negative predicted value of 41.3% (95% CI:23%-61%) in the detection of lung cancer.The sensitivity and specificity of diagnosis of mediastinal tuberculosis lymphadenitis were 72.4% (21/29) (95% CI:53%-87%) and 100.0% (95% CI:82%-100%);while sensitivity and specificity of diagnosis of sarcoidosis were 71.4% (5/7) (95% CI:29%-96%) and 100.0% (95% CI:91%-100%).Conclusions:The sensitivity and specificity of EBUS-TBNA do not significantly differ for a diagnosis of lung cancer versus tuberculosis or sarcodosis.
