2.Research progress of white matter injury following congenital heart disease
International Journal of Pediatrics 2017;44(8):519-522
Congenital heart disease is the most common birth defect.With the significant improvements of cardiac surgical techniques,the survival of newborns and infants with complex congenital heart disease(CHD) has obviously been increased.However,neurological sequelae are still common and up to 25 % ~50%.The most important lesion after CHD surgery is white matter(WM) injury.Recent studies show that periventricular leukomalacia disease characterized by WM injury is common in C-HD infants especially after cardiac surgery.It is previously thought to be due to the cardiopulmonary bypass and surgical operation.However,with the advances in surgery and medical diagnostic technology and development of basic research in recent years,it is discovered that WM injury in infants with CHD is a complex lesion influenced by preoperative,operating and postoperative factors.The movement disorders and the defects of attention,learning and other aspects in the late growth of these children bring a huge economic burden to the family and society,reducing the quality of the population.Therefore,exploring etiology,mechanisms and control methods of WM injury in infants with CHD becomes a hot topic in recent years,and it may also become an important direction for future research,aiming to the significant improvements in CHD children with neurodevelopmental damages.

AIM: To study the effects of chromium rutin synthesized with rutin and chromium (Ⅲ) on metabolism of blood lipid. METHODS: The effects of chromium rutin on metabolism of blood lipid were evaluated by the changes of triglyceride, cholesterol, HDL cholesterol, and LDL cholesterol in normal rats and the rats with high blood lipid. RESULTS: Chromium rutin could increase the blood chromium, decrease the concentrations of triglyceride, cholesterlo and LDL cholestelol,and increase the concentration of HDL cholesterol in normal and the rats with high blood lipid rats. CONCLUSION: Chromium rutin has an effect on the blood lipid in rats.
5.Research progress of pathogenesis of cryptococcal meningitis
Chinese Journal of Applied Clinical Pediatrics 2016;31(10):721-724
Cryptococcus neoformans(CN) is a kind of opportunistic fungal pathogen which has a predilection for the central nervous system,resulting in devastating meningitis.The management of cryptococcal meningitis remains challenging because of its high mortality,the toxicity and uncertainty effect of antifungal therapy.In recent years,the study of the mechanism of neurotropism of CN has made a great progress.Many violence factors of this pathogen and several signal pathways of the host involved in this process have been discovered.Combination therapy with immunotherapy to regular antifungal treatment has become an important adjuvant method.The present review will concisely present current progress of pathogenesis and immunotherapy of cryptococcal meningitis.
6.Clinical study on the cerebrospinal fluid antigen test for rapid diagnosis of pneumococcal meningitis
Chinese Journal of Infectious Diseases 2017;35(1):35-38
Objective To evaluate the value of Binax NOW pneumococcal antigen test for rapid diagnosis in patients with purulent meningitis.Methods Cerebrospinal fluid (CSF) were collected prospectively from 86 children who were diagnosed with purulent meningitis in the Department of Infectious Diseases at Beijing Children′s Hospital from March 2013 to March 2014 and were tested by Binax NOW method.CSF culture was considered as golden standard to evaluate the sensitivity and specificity of the Binax NOW method.Continuous variables were compared with t test, categorical variables were compared with χ2 test.Results Among 86 cases of purulent meningitis, 34 (39.5%) had positive culture and 21 (24.4%) were Streptococcus pneumonia, while 31 (36.0%) were positive by Binax NOW test.Using CSF culture as golden standard, the sensitivity and specificity of Binax NOW for diagnosis of pneumococcal meningitis were 90.5% (19/21) and 81.5% (53/65), respectively.Conclusion Binax NOW pneumoniae antigen test in CSF yields high sensitivity and specificity, which is useful in clinical application and enables prompt and adequate treatment.
7.Application progress of exercise electrocardiography test in the diagnosis and treatment of coronary artery disease
Tianjin Medical Journal 2017;45(4):432-436
With the improvement of people's living standard and changes of their lifestyle, the incidence of coronary artery disease (CAD) has increased quite significantly, which has attracted great concern. Examination methods for CAD are more and more advanced, while the cost of inspection is rising. As a traditional test, the exercise treadmill test (ETT) is convenient, safe, and cheap. ETT can be conducted in almost every hospital as it doesn't need advanced equipments. The values of some new evaluation indexes for diagnosis and prognosis of CAD are reviewed in this article.
8.Critical antimicrobial resistance threats in Chinese children
Chinese Journal of Applied Clinical Pediatrics 2016;(4):241-244
Antimicrobial resistance has been identified as one of the world′s most pressing public health threats.The number of antibiotic -resistant bacteria and the diversity of molecular mechanisms of resistance have in-creased sharply in recent years.The presence of antimicrobial resistance in children complicates patient management and arouses widespread concern.The use of antimicrobial agents is the single most important factor leading to the deve-lopment of resistance.New effective antimicrobial agents has been needed but has not kept pace.Antimicrobial -resis-tant infection can be prevented by immunization as well.Appropriate and judicious use of antimicrobial agents is the most important factors contributing to control resistance.Clinicians should collaborate well with microbiologist and know well about resistant bacteria and its proper antimicrobial drugs.A good application of antibiotic formulary restriction has the potential to decrease antimicrobial resistance.An antimicrobial resistance surveillance between regions and countries is urgently needed.It can help us to understand and slow antimicrobial resistance in the long run.
