Objective To increase the awareness of thyroid diseases through observing the relationship between ultrasound indications of thyroid and thyroid disease,and to enhance the understanding of thyroid disease through outpatient data.Methods Two hundred women aged 25 to 50 with thyroid imaging data were selected from the Department of Ultrasonography,the First Affiliated Hospital of Harbin Medical University.Seven indications including age,body weight,thyroid volume,the number of nodules,nodule size,nature of nodules and thyroid disease were recorded.Thyroid cases were divided into four groups based on their sonographic changes of color Doppler ultrasound:normal group (136 cases):sonographic changes of thyroid were approximately normal ; mild degree group (9 cases):consisting of patients with mild thyroid disease,diffused thyroid enlargement or combined cystic nodules; moderate degree group (38 cases):consisting of patients with moderate thyroid disease,hyperthyroidism or hypothyroidism; severe degree group (17 cases):consisting of patients with severe thyroid disease,thyroiditis and/or with hemorrhage and calcification.Data were analyzed using the method of clinical case observation and SPSS 16.0.Results We found that in mild degree group the discriminant coefficients of thyroid volume,the nature of thyroid nodules and nodule size were 0.085,0.169 and 0.695; but in sever degree group the corresponding values were 0.158,0.344 and 0.484,respectively,and the difference between the two groups was statistically significant (x2 =43.3,df =18,P ＜ 0.01).Conclusions The nature,size and area of thyroid nodules are closely related to the progression of thyroid disease.The color Doppler ultrasound data of outpatients as a part of hospital statistics have important theoretical and practical value.

Objective To investigate the reliability of extravascular lung water index (EVLWI) and pulmonary vascular permeability index (PVPI) in assessing the severity of acute respiratory distress syndrome (ARDS) in critically ill patients.Methods Forty-six patients with ARDS,who were admitted in our emergency intensive care unit,aged 18-72 yr,weighing 46-72 kg,of Acute Physiology and Chronic Health Evaluation Ⅱ score 11-25,were divided into 3 groups:PaO2/FiO2 ≤ 100 mmHg severe group (n =16);100 mmHg ＜PaO2/FiO2 ≤ 200 mmHg moderate group (n =14);200 mmHg ＜PaO2/FiO2 ≤ 300 mmHg mild group (n=16).Before treatment,and at 24 and 72 h after diagnosis of ARDS,PVPI,EVLWI,cardiac index (CI),and intrathoracic blood volume index (ITBVI) were measured,and blood gas analysis was performed.PaO2/FiO2 was calculated.The 28 day fatality after admission to hospital was recorded.Person correlation of PVPI and EVLWI with PaO2/FiO2,ITBVI and CI was analyzed.Results The PVPI,EVLWI and fatality rate were significantly higher at each time point in moderate group and severe group than in mild group,and in severe group than in moderate group (P＜0.05).The correlation coefficient between PVPI and PaO2/FiO2 was 0.778,and between EVLWI and PaO2/FiO2 was-0.437 (P＜0.05).There was no correlation between CI and ITBVI (P＞0.05).The correlation coefficient between EVLWI and PaO2/FiO2 was-0.448,and between EVLWI and ITBVI was 0.347 (P＜0.05).There was no significant difference between the correlation coefficient between PVPI and PaO2/FiO2 and the correlation coefficient between EVLWI and PaO2/FiO2 (P＜0.05).Conclusion PVPI and EVLWI both can assess the severity of ARDS in critically ill patients,showing a consistent reliability.

Objective:To investigate the efficacy of the combined application of fluconazole and sodium bicarbonate in treatment of oral fungal infections among elderly patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:A total of 360 elderly patients with AECOPD treated in the Emergency Ward of our hospital during July 1, 2018 and December 31, 2019, were included for observation. After admission, the oral mucosal lesions were observed every day, and fungal smear and fungal culture were performed immediately once signs of fungal infection appeared. Meanwhile, fluconazole was given with 300 mg. oral. qd., followed by 150 mg. oral. qd., and 2.5% sodium bicarbonate was given three times a day as gargle.Results:The prevalence of oral fungal infection was 8.3% among which candida infection accounted for 83.2%. The mean treatment time was 5.0 ± 0.3 days. Daily observation of the oral cavity, early detection and application of fluconazole combined with sodium bicarbonate had significantly clinical effect in elderly AECOPD patients with oral fungal infection, with an effective rate of 16.7%, and a cure rate of 83.3%. No toxic side effects on liver and kidney function were found during the treatment. Obvious efficacy was found in relieving clinical symptoms, and there was no increase in hospitalization costs and time.Conclusion:Early combination of fluconazole and sodium bicarbonate has a significant clinical effect on control of oral fungal infection in elderly patients with AECOPD.
