Objective To compare the changes of BNP and IL-1βin patients with chronic heart failure combined with chro-nic periodontitis before and after periodontal intervention treatment and investigate the improve effect of periodontal intervention treat-ment on the prognosis of chronic heart failure.Methods 38 patients with chronic heart failure combined with chronic periodontitis were divided into the intervention group (n=20) and the control group (n=18).The intervention group was given periodontal inter-vention and the control group was only given oral hygiene education .The baseline and changes of bleeding index , periodontal attach-ment loss and BNP, IL-1βof the two groups were recorded respectively.Results After periodontal treatment, the bleeding index, periodontal attachment loss and the baseline in the intervention group were significantly differenct compared with the control group (p<0.05).The changes of BNP and IL-1βindex in the intervention group were also significantly different from those of the control group (p<0.05).Conclusion The oral hygiene and periodontal health status of the patients could be improved by periodontal inter-vention.It can also improve the prognosis of patients with periodontitis combined with chronic heart failure .In conclusion, the perio-dontal intervention treatment plays a positive role in the treatment of chronic heart failure disease .

ObjectiveTo explore the convenient and effective therapeutic methods for acute lumbar strain on the basis of classification and mechanism of acute lumbar strain.MethodsAcute lumbar strain was classified into post-lumbar joint disturbance type, post-lumbar joint embedded type, muscular strangulated type, muscular strain, sacroiliac joint malposition and mixed type.The repulsion reposition, orthodromic allocation, repulsion ilium and moving leg combioned with high electric frequence were chosen according to the patients' age and somatic condition.ResultsAfter 1-3 times curing, the symptom and appearance of the patients were obviously improved, even more recovery. In these 100 cases,52 patients were cured,39 patients were obviously improved, 9 patients were better than before, the rate of obvious effect was 91%.ConclusionsManipulation combined with high electrical frequence is a convenient, safe and effective method for acute lumbar strain.

Objective: This study aims to determine the prevalence of overweight and obesity and associated early life factors among children aged 2 to 6 years in a community in Guangzhou. Methods: A stratified cluster sampling was used to select 922 children from one community in Guangzhou in 2018. The survey included a questionnaire survey and physical examination. Logistic regression analyses were performed to examine the relationship of early-life factors and obesity. Results: The prevalence of overweight and obesity was 13.4% in 922 children(16.1% in boys and 10.1% in girls). The sex difference in prevalence of overweight and obesity was statistically significant(Z=2.69, P<0.05). Overweight and obesity was found significantly higher in children with large for gestational age, caesarean section, artificial feeding within 6 months, maternal pre-pregnancy overweight and obesity, maternal excessive weight gain(P<0.01). Large for gestational age (OR=2.62, 95%CI=1.42-4.82), caesarean section(OR=1.59, 95%CI=1.08-2.36), artificial feeding within 6 months(OR=2.00, 95%CI=1.19-3.37), maternal pre-pregnancy overweight or obesity(OR=1.97, 95%CI=1.08-3.58), and excessive gestational weight gain (OR=2.07, 95%CI=1.26-3.39) was positively associated with childhood overweight obesity(P<0.05). Maternal pre-pregnancy underweight was negatively associated with childhood overweight obesity(OR=0.51, 95%CI=0.29-0.88, P<0.05). Conclusion Early-life risk factors are positively associated with the risk of overweight and obesity in later childhood, including large gestational age, caesarean section, artificial feeding within 6 months, maternal pre-pregnancy overweight and excessive gestational weight gain, while maternal pre-pregnancy underweight associates with low risk of child overweight and obesity. These findings suggest that early intervention to these modifiable risk factors could make a significant contribution to childhood obesity prevention.
