Objective To analyze the clinical features of chronic obstructive pulmonary disease (COPD) patients with heart failure (HF) in Nanjing and explore the influencing factors. Methods A total of 773 COPD inpatients were selected from January 2021 to January 2024 in Nanjing Combined Hospital of Traditional Chinese and Western Medicine, Nanjing Qixia District Hospital, Nanjing Lishui District People's Hospital, Nanjing Pukou District Hospital of Traditional Chinese Medicine and Nanjing First Hospital., and were divided into 2 groups according to the presence or absence of combined HF. The general data and medical records of the two groups were compared, the clinical characteristics of COPD patients with HF were summarized, and the influencing factors of COPD patients with HF were analyzed by multivariate logistic regression. Results Among the 242 patients (31.31%) with COPD had HF, chronic paroxysmal dyspnea was the most common first symptom, 169 patients (69.83%) had left heart failure, 63 patients (30.17%) were diagnosed as right heart failure or global heart failure , 17 patients (7.02%) had myocardial infarction. Multivariate logistic regression analysis showed that the risk of HF was 1.678 times and 1.691times higher in COPD groups ≥ 50 years old and male COPD groups than in < 50 years old and female groups, respectively; the risk of HF was 1.491 times higher in COPD groups engaged in physical work than in physical work groups; the risk of HF was 1.447 times and 1.580 times higher in COPD groups with hypertension and coronary heart disease than in COPD groups without hypertension and coronary heart disease, respectively; the risk of HF was 1.859 times higher in COPD groups smoking>400 vial/year than in COPD groups≤400 vial/ year; the risk of HF was 1.757 times higher in COPD groups with acute exacerbation frequency≥2 times/year than in COPD groups<2 times/year; the above differences were statistically significant (P<0.05). Conclusion Attention should be paid to elderly, male and heavy physical work group of COPD patients. Active treatment of hypertension and coronary heart disease, effective tobacco control and reduction of the frequency of acute exacerbation are effective ways to reduce the risk of HF in COPD patients in Nanjing.

Objective:To describe the distribution of fat-free mass (FFM) and fat-free mass index (FFMI) in children aged 3-17 years in China.Methods:Data were collected from National Nutrition and Health Systematic Survey in 0-18 years old children in China. By using multi-stage stratified randomized cluster sampling method, the project was conducted in 28 survey points in urban and rural areas in 14 provinces (autonomous regions and municipalities) in 7 regions in China from 2019 to 2021. FFM was measured using bioelectrical impedance meter. Finally, the body composition data of 70 853 children were included in the analysis. M ( Q1, Q3) was used to describe the gender and age specific FFM and FFMI of the children in different regions. Kruskal-Wallis H rank sum test was used to compare FFM and FFMI of boys and girls in same age group, boys in different age groups, girls in different age groups, as well as boys in same age group and girls in same age group in different regions. DSCF method was used for pairwise comparisons. Results:After the age of 11 years, the difference of FFMI between boys and girls increased year by year. The FFMI was 14.2 kg/m 2 in boys and 13.8 kg/m 2 in girls at 11 years old, the difference was significant ( χ2=135.86, P<0.001). The difference of FFMI between boys and girls exceed 1.0 kg/m 2 from 12 years old, and FFMI was 15.3 kg/m 2 in boys and 14.2 kg/m 2 in girls at 12 year old, the difference was significant ( χ2=597.27, P<0.001). The FFMI was 17.5 kg/m 2 in boys and 14.7 kg/m 2 in girls at 16 years old, the difference was significant ( χ2=2 543.60, P<0.001). The FFMI was higher in boys in northeast China, while the FFMI was lower in both boys and girls in northwest China. Conclusions:Gender specific difference was observed in the increase of FFMI with age. The FFMI was significantly higher in boys than in girls after 11 years old. It is necessary to pay attention to the problem of FFM in children in northeastern and northwestern China.

Objective:To investigate the distribution characteristics of body height, body weight and body mass index (BMI) in children aged 3-17 years in China.Methods:Data were obtained from the National Nutrition and Health Systematic Survey in 0-18 years old children in China. The study selected 70 853 children aged 3-17 years from 28 urban and rural survey sites in 14 provinces (autonomous regions and municipalities) in 7 regions of China with multi-stage stratified cluster random sampling. M ( Q1, Q3) was used to describe the region, age and gender specific body height, body weight and BMI in the children aged 3-17 years. Wilcoxon rank sum test was used to compare the body height, body weight, and BMI between boys and girls in same age group. Kruskal-Wallis H rank sum test was used to compare the body height, body weight and BMI among boys in different age groups and among girls in different age groups, as well as among boys in same age group and among girls in same age group from different regions, and DSCF method was used for further pairwise comparisons. Results:In this study, the median body height and body weight were 172.0 cm and 62.9 kg in 17-year-old boys and 160.0 cm and 53.7 kg in 17-year-old girls. The median for children's body height, body weight, and BMI in most age groups were higher in northeastern and northern China than in southern China, and the differences could be observed until age 17 years. The differences in body weight and BMI in children in northeastern and northern China were greater in Q3 than in Q1 compared with southern China. Conclusions:The body height of children aged 3-17 years continues to increase in China. Northeastern and northern China have more children with higher bodyweight, showing an obvious body weight increase trend, to which close attention needs to be paid.

Objective:To describe the distribution of fat mass (FM), fat mass percentage (FMP), and fat mass index (FMI) in children aged 3-17 years in China.Methods:Data of this study were from the National Nutrition and Health Systematic Survey in 0-18 years old children in China. A total of 70 853 children aged 3-17 years old selected from seven regions of China were included in this analysis. Body composition were measured by using bioelectrical impedance meter. The region, gender and age specific FM, FMP and FMI of the subjects were described by using M ( Q1, Q3). Kruskal-Wallis H rank sum test was used for the comparison of intergroup differences. DSCF method was used for pairwise comparisons. Results:The medians of FM, FMP and FMI were 3.0 kg, 18.3% and 2.9 kg/m 2 in boys aged 3 years and 2.9 kg, 19.0% and 2.9 kg/m 2 in girls aged 3 years, respectively. The FM increased with age and the FMP and FMI decreased with age in both boys and girls aged 3-5 years. After 11 years old, the FM, FMP and FMI decreased first and then increased in boys. From 6-17 years old, the FM, FMP and FMI increased gradually in girls. The FM, FMP and FMI were higher in girls than in boys after 12 years old (all P<0.05). The FM, FMP and FMI were relatively higher in children at the age of 6-14 in northeastern and northern China than in other regions. Conclusions:The age specific FM, FMP and FMI had different changing characteristics in boys and girls aged 3-17 years in seven regions of China. The FM, FMP and FMI also differed with region.

Objective:To analyze the relationship between body mass index (BMI) and fat mass percentage (FMP) in children aged 3-17 years in China.Methods:The BMI and FMP data of children aged 3-17 years from the National Nutrition and Health Systematic Survey in 0-18 years old children in China was analyzed. BMI- Z score/BMI and FMP were used to classify the subjects, respectively. Spearman correlation was used to analyze the correlation between BMI and FMP. The consistency between BMI- Z score/BMI and FMP in classifying the subjects was measured using Kappa coefficient. Results:The FMP of malnutrition, normal and overweight/obesity in boys was higher in age group 10-13-year than in other age groups (all P<0.001). The FMP of all nutritional status in girls increased with age (all P<0.05). The BMI of boys in all the FMP levels increased with age (all P<0.05). When the FMP of girls was 25%- or ≥30%, BMI increased with age (all P<0.001). The relationship between BMI and FMP was strong ( r=0.705, P<0.001), with r of 0.618 in boys and 0.884 in girls. The consistency between BMI- Z score/BMI and FMP in classifying the subjects was found to be moderate (Kappa=0.574, P<0.001). Conclusions:There was a strong relationship between BMI and FMP. The consistency between BMI- Z score/BMI and FMP in classifying the subjects was moderate.

Objective:To evaluate the consistency between bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) in the measurement of body composition in children aged 6-17 years in China.Methods:Fat-free mass, fat mass and fat mass percentage were measured by both BIA and DXA in 1 161 children. t-test or Wilcoxon paired test was used to evaluate the different outcome of the two methods. The correlation and consistency between the methods were evaluated by Spearman correlation coefficients ( r) and Bland-Altman analysis. Results:Body compositions measured by BIA was positively correlated with those measured by DXA (fat mass r=0.95, fat-free mass r=0.98, fat mass percentage r=0.86, all P<0.05). Comparing with DXA, BIA underestimate children's fat mass [the mean difference is -3.15 kg, and the SD is 2.35 kg, 95% limits of agreement (LoA): -7.74-1.45 kg] and fat mass percentage (the mean difference is -8.45%, and the SD is 4.63%, 95% LoA: -17.53%-0.64%). Conclusions:Body compositions measured by BIA was highly positively correlated with those measured by DXA. BIA has certain application value in the measurement of body fat mass and fat-free mass of children aged 6-17 years.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

Objective:To explore the morbidity features and therapeutic outcomes of rejections in pediatric kidney transplantation (KT) recipients.Methods:Between January 2013 and June 2022, 360 children undergoing KT were recruited.The relevant clinical data were collected for examining the morbidity features and therapeutic outcomes of rejections.The serum levels of creatinine were compared among groups by non-parametric rank test.And Kaplan-Meier and Log-rank methods were employed for examining the incidence of rejection and comparing mortality-censored graft survival rates among patients with different times of rejection.Results:A total of 58 recipients had 82 incidents of rejection with a cumulative incidence of 6.3%, 9.2% and 11.3% at 3/6/12 months respectively.Among 50 incidents of biopsy-proved rejections, the types were T cell-mediated rejection [TCMR, 42.0%(21/50)], antibody-mediated rejection [20.0%(10/50), ABMR] and mixed rejection [38.0%(19/50)].Among 58 incidents of initial rejection, 69% had maintained graft function (MGF) and 31% impaired graft function (IGF) after anti-rejection regimens.Among 80.8%, 85.7% and 75% of recipients with clinical rejection, ABMR or borderline rejection while 36.4% in TCMR patients had MGF.Fifteen kidney allografts lost function in 58 recipients with rejection.Five-year death-censored graft survival was significantly lower in patients with two or more incidents of rejection (30.5%, 95% CI: 12.3%-75.4%) than in those without rejection (92.9%, 95% CI: 89.3%-96.6%) ( P<0.000 1) or with only one rejection (82.9%, 95% CI: 65.9%-100%)( P<0.001). Conclusions:The rejection rate remains high in KT children and it affects graft survival.And TCMR is more likely to cause impaired graft function.Recurrent rejections have a more pronounced impact upon graft survival.

OBJECTIVE: To explore the diagnosis and treatment of acute cerebral infarction following extracorporeal membrane oxygenation (ECMO) therapy in patients with cardiogenic shock to review the literature. METHODS: The clinical data of two patients with cardiogenic shock treated with veno-arterial ECMO (VA-ECMO) complicated with acute cerebral infarction admitted to department of intensive care unit (ICU) of Affiliated Hospital of Guizhou Medical University were retrospectively analyzed and the treatment experience was shared. RESULTS: Case 1 was a 46-year-old male patient who was admitted to the hospital on September 16, 2021, due to "repeated chest tightness, shortness of breath, syncope for 2+ years, and worsened for 15 days. Coronary artery angiography showed 3-vessel coronary artery disease lesions. On October 15, 2021, coronary artery bypass grafting (CABG), pericardial fenestration and drainage, thoracic closed drainage, femoral bypass, thoracotomy exploration, and sternal internal fixation were performed under support of extracorporeal circulation. After surgery, the heart rate was 180-200 bpm, the blood pressure could not be maintained, and the improvement was not obvious after active drug treatment. The right femoral artery and femoral vein were intubated, VA-ECMO support treatment was performed, and the patient was transferred to the ICU. Intra-aortic balloon pump (IABP) was treated on the day of transfer because the circulation could not be maintained. Due to acute cerebral infarction in the left hemisphere and right parieto-occipital lobe, subfalcine herniation, tentorial herniation, the patient ultimately died after withdrawing from ECMO. Case 2 was a 43-year-old male patient who was admitted to the hospital on June 29, 2021, with "fever for 8 days and vomiting for 4 days". Bedside ultrasound showed cardiac enlargement and diffuse wall motion reduction in the left and right ventricles. On June 30, 2021, the patient underwent catheterization through the right femoral artery and femoral vein, VA-ECMO support, and was transferred to ICU for treatment. Acute cerebral infarction on both sides of the cerebellum occurred, and after treatment, the patient was discharged with mild impairment of daily living ability. CONCLUSIONS Strengthen monitoring of anticoagulation; regular neurological examination of patients undergoing ECMO therapy; ECMO under light sedation or awake can be performed if the condition permitsif the condition permits, perform light sedation or awake ECMO, which helpful for the early detection of nervous system injury.

【Objective】 To investigate the effects of total flavone of oldenlandia diffusa (FOD) on the proliferation and apoptosis of hepatocellular carcinoma (HCC) stem cells sorted from Huh7. 【Methods】 Human HCC cell lines Huh7 was cultured in vitro; CD133 positive (CD133⁺) stem cells in Huh7 cell line were sorted by flow cytometry, and stem cell markers such as Nanog, Oct4 and Sox2 were tested by Western blotting. CD133⁺-Huh7 was stimulated by different concentrations (0 μg/mL, 50 μg/mL, 100 μg/mL and 400 μg/mL) of FOD for different time (24 h, 48 h, 72 h and 96 h). CCK8 and plate cell cloning assay were used to detect the effect of FOD on CD133⁺-Huh7 proliferation while Annexin V-PE/7-AAD was used to detect the effect of FOD on CD133⁺-Huh7 apoptosis. Western blotting was used to detect the protein expressions of protein 53 (P53), factor associated suicide-Fas-associating protein with a novel death domain (Fas-FADD), B-cell lymphoma-2 (Bcl-2), Cleaved-Caspase3, and Bcl-2 associated X protein (Bax). 【Results】 More than 95% of stem cells were purified for further experiments. Cell proliferation of CD133⁺-Huh7 was significantly inhibited by FOD, with the significant suppression at the concentration of 100 μg/mL for 72 h compared with negative control group (P<0.05). The apoptosis rate was significantly upregulated than that in the negative control group (P<0.05). The protein expression of Bcl2 decreased while Bax and Cleaved-Caspae3 increased via FAS/FADDD and P53 axis. 【Conclusion】 FOD can significantly inhibit the proliferation and promote the apoptosis of CD133⁺-Huh7.
