Objective To investigate the correlation between the expressions of negative regulatory cell CD4⁺CD25⁺T and its related cytokines in peripheral blood and bacterial infection of patients with chronic obstructive pulmonary disease (COPD). Methods Sixty-six COPD patients admitted between January 2018 and December 2019 were included as the research subjects, including 36 patients with acute exacerbation of COPD (AECOPD) and 30 patients with stable COPD. Another 30 healthy people undergoing physical examination during the same period were included in control group. The expression levels of CD4⁺CD25⁺ regulatory T cell and its related cytokines [interleukin-4 (IL-4), interleukin-10 (IL-10), interferon-γ (IFN-γ)] in the peripheral blood samples were detected among the included subjects. The relationship between levels of related indicators and presence or absence of bacterial infection in COPD and the efficacy of predicting infection were analyzed. Results The levels of CD4⁺, CD4⁺CD25⁺ and IFN-γ/IL-4 in patients with AECOPD and patients with stable COPD were lower than those in control group (P<0.05), while the levels of IL-4 and IL-10 were higher than those in control group (P<0.05). The IFN-γ level of AECOPD patients was higher than that of control group (P<0.05). The levels of CD4⁺ and CD4⁺CD25⁺of AECOPD patients were lower than those of stable COPD patients (P<0.05), while the levels of IL-4, IL-10 and IFN-γ were all higher than those of stable COPD patients (P<0.05). The levels of CD4⁺ and CD4⁺CD25⁺were negatively correlated with IL-4 and IFN-γ (P<0.05), and the CD4⁺level was negatively correlated with IL-10 (P<0.05). The CD4⁺ level in COPD patients with infection was lower than that in patients without infection (P<0.05), while the levels of IL-4 and IFN-γ were higher than those in patients without infection (P<0.05). The CD4⁺CD25⁺level of COPD patients with Gram-negative bacteria infection was lower than that of patients without infection (P<0.05), while the IL-10 level was higher than that of patients without infection (P<0.05). CD4⁺, IL-4, IL-10 and IFN-γ were effective indicators in predicting bacterial infection in COPD patients (P<0.05), and IL-4 and IFN-γ had higher efficacy. Conclusions CD4⁺, CD4⁺CD25⁺ T cell and related cytokines are involved in the occurrence and development of COPD and bacterial infection in patients. Monitoring changes of those levels is helpful to provide information for clinical diagnosis and treatment.

Objective To investigate the correlation between serum homocysteine (HCY), heme oxygenase-1 (HO-1) levels and coronary Gensini score in patients with coronary artery disease. Methods One hundred and eight patients with coronary artery disease diagnosed by coronary angiography in the cardiology department of our hospital from March 2020 to July 2021 were randomly included in observation group, while 33 healthy people without coronary artery disease confirmed by coronary angiography in our hospital during the same period as the control group. The 108 patients with coronary artery disease were divided into low (n=42), medium (n=35) and high (n=31) groups by coronary Gensini score.

Objective To explore the clinical characteristics of children with enterovirus associated encephalitis, in order to provide some help for clinicians to understand the disease. Methods The clinical data of 37 children with enterovirus related encephalitis treated in the infection department of Guangzhou Women and Children's Medical Center from January 2018 to December 2019 were analyzed retrospectively. Results There were 28 males and 9 females, with a male to female ratio of 3.11:1. The main clinical symptoms and signs were fever (97.30%), oral herpes and/or rash (54.05%); the common nervous system symptoms were vomiting (56.76%), headache (56.76%) and convulsion (29.72%). There were significant differences in convulsion, vomiting and headache symptoms between ≤ 1 year old group and other age groups. The leukocytes level in cerebrospinal fluid was elevated. All children recovered and discharged without neurological sequelae. Conclusions Nearly half of children with enterovirus associated encephalitis had no clinical manifestations of pharyngeal herpes or rash. The main manifestations of children under 1 year old were fever and convulsion. The main manifestations of children over 1 year old, especially preschool and school-age patients, were fever and vomiting with headache. Early diagnosis and treatment had good prognosis.

目的 探讨健康儿童的个体因素对超声测量下腔静脉内径的影响。方法 使用超声测量210例健康儿童的下腔静脉呼气末内径及腹主动脉内径,并记录他们的个体特征,包括性别、年龄、身高、体质量、腰围、体表面积等,进行相关与回归分析。结果 年龄、身高、体质量、腰围、体表面积与下腔静脉和腹主动脉内径呈正相关。年龄是女性儿童下腔静脉内径唯一的独立影响因素,身高是男性儿童下腔静脉内径唯一的独立影响因素。无论男性或女性,年龄是儿童腹主动脉内径的独立影响因素,而下腔静脉和腹主动脉内径的比值不受这些个体因素的影响。结论 下腔静脉和腹主动脉内径易受个体因素影响,而它们的比值不易受个体因素影响,可以更好的用于预测儿童的容量特征。

Objective To explore the impact of individual characteristics on inferior vena cava diameter ( IVC ) in healthy children. Methods IVC_max and abdominal aorta (AO) diameters were measured by ultrasound in 210 healthy children. The individual characteristics including gender, age,height,weight, waist circumference of each child were recorded. Then the surface area(BSA) and IVC_max/AO were calculated to discuss the relationship between them with multivariate analysis. Results Age, height, weight,waist circumference, and BSA were positively correlated with IVC_max and AO. Multivariate linear regression showed that age was the only independent variable for IVC_max in female children, height was the only independent variable for IVC_max in male children, and age was the only independent variable for AO in both females and males. IVC_max/AO was not significantly influenced by the subjects' characteristics. Conclusion IVC_max and AO were more susceptible to subjects' characteristics than IVC_max/AO. IVC_max/AO could be a reliable and practical parameter in children as it was independent of age, height, and weight.

Objective To explore the clinical value of echocardiographic evaluation of myocardial injury caused by pulmonary hypertension (PAH) and the correlation of oxidative stress injury. Methods Forty-eight 12-week-old SD rats were collected. They were randomly divided into 4 groups: blank control group, NaCl control group, PAH 2-week group and PAH 4-week group. After modeling, ultrasound was used to detect relevant parameters. HE and Masson staining were used to observe the distribution of myocardial cells and collagen fibers in the right ventricle. Superoxide dismutase (SOD) activity, reduced glutathione (GSH) and malondialdehyde (MDA) levels were measured, and their correlations with ultrasound parameters were evaluated. Results The ultrasound-related parameters of rats in the PAH group changed significantly and gradually increased.HE and Masson staining showed that cardiac myocytes were enlarged and collagen fibers in myocardial interstices were increased, and it was more obvious in the 4-week group.In the PAH group, the SOD activity and GSH levels were lower, while the MDA levels were higher, and there was a trend of change, and there was a significant correlation with ultrasound parameters. The difference was statistically significant (P<0.05). Conclusion PAH causes changes in the myocardial tissue structure of the rat right ventricle, as well as changes in oxidative stress-related indicators.

Objective To analyze the characteristics, diagnosis and treatment of severe influenza-associated encephalopathy in children. Methods The clinical data of 17 children with severe influenza-associated encephalopathy admitted to PICU from May 2017 to April 2020 were retrospectively analyzed. Results Among the 17 cases, 10 were male and 7 were female, and the onset age was 3 (2-5) years old. All children developed fever, and neurological symptoms 1 (0-3.5) days later, including seizures (88%) and coma (88%). The lesions were mainly distributed in the thalamus, brainstem and medullary ventricular white matter, showing symmetry and multifocal changes. All the 5 cases with slowed cerebral blood flow velocity and presented shock wave or nail wave died. 16 children were on mechanical ventilation, 2 with continuous renal replacement therapy, and 8 died. All the survivors had varying degrees of neurological damage before discharge. Conclusion Severe influenza-associated encephalopathy of childhood is mainly characterized by fever, convulsions and coma. Cranial imaging, EEG, TCD and other examinations are helpful for early diagnosis and prognosis judgment. The effectiveness of early combined application of methylprednisolone and IVIG still needs further study.
