Chinese Journal of Applied Clinical Pediatrics 2017;32(6):408-411
Childhood pneumonia,especially severe pneumonia is the leading cause of death in children under 5 years old,so,early diagnosis and reasonable management are particularly important for reducing mortality of children with severe pneumonia.At present,the diagnostic criteria of severe pneumonia in children is not unified,resulting in the lack of comparability in clinical research of different hospital.The policy guidance of clinical research is weak in Chinese future development of appropriate countermeasures.This paper mainly introduces the diagnosis criteria of severe pneumonia from China,World Health Organization,British and American in children,illustrates their advantages and disadvantages,and to provide a reference for pediatricians in using different diagnostic criteria.
2.Controversies of Sepsis-3
Chinese Pediatric Emergency Medicine 2017;24(7):481-485
Sepsis caused by infection is one of the most common diseases in ICU.In 1991,the concept of sepsis was first put forward for the purpose of unifying cognition,early diagnosis and treatment,and reducing the fatality rate of severe infection.Over the past 20 years,with the development of the septic pathophysiology,its definition and clinical criteria have been constantly updated and improved.In 2016,a task force convened by European Society of Intensive Care Medicine and the Society of Critical Care Medicine revised the definition and clinical criteria of sepsis,namely,Sepsis-3.It mainly emphasizes infection leading to homeostasis disequilibrium,and organ dysfunction with potentially fatal risk.The definition is updated each time;many new theories or ideas are incorporated,and are also some controversies.This review focused on the definition and clinical criteria of sepsis,and the controversies of Sepsis-3.

Objective To investigate the effect of Dexamethasone on microtubule - associated protein 1 light chain 3(LC3)expression of cells and neurons in cerebral cortex of juvenile Wistar rats with sepsis. Methods Models of juvenile Wistar rats with sepsis were established through cecal ligation and puncture(CLP). Totally 60 cases of 30 -day - old juvenile male Wistar rats were randomly divided into sham - operation group(10 cases),non - treated group (25 cases)and Dexamethasone group(25 cases). Twelve hours after CLP,rats in Dexamethasone group were injected with Dexamethasone(1 mg / kg)via tail vein every other day,with a total of 3 times. The same dose of saline was used in the non - treated group. All rats were killed at the age of 40 days. Expressions of LC3 and neuronal nuclei(NeuN)of cells in cerebral cortex of rats were detected by using immunofluorescence assay,and the number of positive cells was calculated by using image analysis system software. Expressions of LC3 - Ⅰ and LC3 - Ⅱ protein were measured by a-dopting Western blot. Results Three hours after CLP,rats appeared to be curled up and showed piloerection and shi-vering and the neurobehavioral score in non - treated group was significantly lower than that in sham - operation group (t = 9. 895,P = 0. 000). Twelve of 25 rats in Dexamethasone group died in 10 days after CLP(48% ),while 8 of 25 rats in non - treated group died(32% ),and the difference was not statistically significant between the 2 groups(χ2 =1. 333,P = 0. 248). The immunofluorescence staining and image analysis showed the percentage of LC3 positive cells in non - treated group was significantly increased(0. 606 7 ± 0. 030 1 vs 0. 353 3 ± 0. 025 8,t = 15. 644,P = 0. 000;0. 606 7 ± 0. 030 1 vs 0. 270 3 ± 0. 019 4,t = 22. 450,P = 0. 000). In non - treated group,the LC3 expression of cells in the cerebral cortex of rats was up - regulated,and the LC3 - Ⅱ/ LC3 - Ⅰ ratio was significantly higher than that in sham operation group and Dexamethasone group(0. 413 3 ± 0. 022 5 vs 0. 205 0 ± 0. 015 2,t = 18. 802,P = 0. 000;0. 413 3 ± 0. 022 5 vs 0. 185 0 ± 0. 023 5,t = 17. 206,P = 0. 000). The LC3 positive neurons in the cerebral cortex of rats were less in sham operation group and Dexamethasone group. The LC3 positive neurons were more in non - treated group than that in sham operation group and Dexamethasone group(0. 580 0 ± 0. 020 0 vs 0. 298 3 ± 0. 014 7,t =27. 783;P = 0. 000;0. 580 0 ± 0. 020 0 vs 0. 261 7 ± 0. 017 2,t = 28. 614;P = 0. 000). Conclusions The LC3 expres-sion of cells in the cerebral cortex of juvenile Wistar rats with sepsis was up - regulated,LC3 - Ⅱ/ LC3 - Ⅰ ratio in-creased,and the number of LC3 positive neurons also increased,while Dexamethasone could have inhibitory effect on them.
