Objective To investigate the diagnostic value of blood routine, erythrocyte sedimentation rate and C-reactive protein level in children with acute pneumonia. Methods A total of 100 cases of acute pneumonia in children admitted to our hospital from January 2014 to December 2019 were selected as the study group. At the same time, they were divided into an infected group (26 cases) and a non-infected group (74 cases) according to the presence or absence of infection. In addition, 100 healthy children examined in our hospital during the same period were selected as the control group. Blood routine examination, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level were compared between infected and non-infected group; in infection and control group blood routine examination, ESR, C-reactive protein level were compared; in non-infection and control group blood routine examination, ESR, C-reactive protein level were compared. Results The percentage of neutrophils, white blood cell count and C-reactive protein in the infected group were higher than those in the non-infected group (P<0.05). There was no significant difference in erythrocyte sedimentation rate between the two groups (P> 0.05). The percentage of neutrophils, leukocyte count, C-reactive protein and erythrocyte sedimentation rate in the infected group were higher than those in the control group (P<0.05). There was no significant difference in the percentage of neutrophils and C-reactive protein levels between the two groups (P> 0.05), and the white blood cell count and erythrocyte sedimentation rate in the non-infected group were higher than those in the control group (P<0.05). Conclusion In the diagnosis of acute pneumonia in children, it is very important to detect the blood routine, erythrocyte sedimentation rate and C-reactive protein level in children, and it is worthy of clinical use.

Objective To analyze the direct signs, indirect signs, advantages and disadvantages of transthoracic echocardiography in Stanford A-type aortic dissection, and explore the application value of echocardiography in its diagnosis and prognostic evaluation. Methods Retrospectively collect the clinical data of patients with type A aortic dissection diagnosed and treated in our hospital from Sept 2018 to Jun 2020, and analyze the application value of echocardiography and the high-risk factors for poor prognosis during hospitalization. Results The direct signs of transthoracic echocardiography were less sensitive than CTA in the diagnosis of type A aortic dissection, but it was better than CTA in evaluating the structure and function of the affected aortic valve. The incidence of poor prognosis in the hospital was 42%. The cause of type A dissection was mostly related to hypertension. Aortic regurgitation, pericardial effusion, and long operation time were high-risk factors. Conclusion Transthoracic echocardiography has a higher initial screening value for the early diagnosis of type A aortic dissection. It has unique advantages in confining to the aortic sinus dissection and observing whether the aortic valve is involved, the choice of surgical methods and the judgment of prognosis has guiding significance.

Objective Objective To investigate the clinical characteristics and risk factors of elderly patients with acute ischemic stroke complicated with pulmonary infection. Methods A retrospective study was conducted on 1 113 elderly patients with acute ischemic stroke admitted to the department of neurology, Shenzhen Second People's Hospital from July 2017 to October 2019. Among them, 108 patients with stroke complicated with pulmonary infection were included in the infection group and 1 005 patients without concurrent pulmonary infection were included in the control group. The clinical data of the two groups were analyzed by single factor comparison, and the risk factors for pulmonary infection were analyzed by logistic multiple factor regression analysis. Results Single factor analysis showed there were statistically significant differences between the two groups in age (especially elderly patients), length of stay in hospital, atrial fibrillation, history of cerebral infarction, chronic pulmonary disease, dysphagia, slurred speech, and disturbance of consciousness (P <0.05). Multi-factor logistic regression analysis showed that old age (≥80 years old), length of stay in hospital, history of cerebral infarction, dysphagia, slurred speech, and disturbance of consciousness were closely related to pulmonary infection in elderly patients with acute ischemic stroke. Conclusion The independent risk factors of acute ischemic stroke complicated with pulmonary infection in the elderly mainly include old age (≥80 years old), length of stay in hospital, history of cerebral infarction, dysphagia, slurred speech and disturbance of consciousness, which should be paid more attention to clinically.
