ABSTRACT

Objective:To understand the etiology and clinical characteristics of hospitalized severe community-acquired pneumonia(SCAP) in Changchun, and provide scientific basis for its etiology diagnosis and targeted treatment.Methods:The study subjects included 618 children with clinical diagnosis of SCAP who were hospitalized from January 2016 to December 2019.We collected pharyngeal swabs and alveolar lavage fluid from children.Virus isolation, bacterial culture, time-of-flight mass spectrometry, PCR/RT-PCR, colloidal gold method and Optochin test were used to detect the antigen, nucleic acid and protein profiles in the specimen.Results:There were more boys than girls in hospitalized children with SCAP.The peak age of onset was 7 to 12 months.Most cases occurred in winter and spring.The highest detection rate of SCAP virus was 56.15%(347/618); 73.49%(255/347) were positive for one virus, among which the top five were respiratory syncytial virus (27.8%), influenza A virus (23.9%), influenza B virus (16.1%), rhinovirus (12.2%) and metapneumovirus (10.2%). Two viruses were positive for 19.88%(69/347); three viruses were positive for 4.32%(15/347); four viruses were positive for 2.31%(8/347). Atypical microbial infections were 29.77%(184/618), of which Mycoplasma pneumoniae accounted for 95.65%(176/184). Bacterial infections were 17.31%(107/618), mainly Streptococcus pneumoniae(39.25%, 42/107) and Staphylococcus aureus(24.30%, 26/107). The mixed infection of multiple pathogens was 7.61%(47/618), among which the mixed infection rates of Mycoplasma pneumonia with Streptococcus pneumoniae, virus were 40.43% and 34.04%, respectively.High fever, faster breathing, and perioral cyanosis were risk factors for SCAP, with OR and 95% CI of 7.71 and 4.56-13.04, 2.43 and 2.02-2.93, 3.53 and 2.56-4.86, respectively.Viral co-infection occurred in 36.96%(34/92) of complications such as heart failure, toxic encephalopathy, and myocardial damage; Mycoplasma pneumoniae and other pathogens co-infected 35.29% of children with pleural effusion. Conclusion:The pathogens of SCAP in Changchun are mainly viruses notably, respiratory syncytial virus is the dominant pathogen, followed by Mycoplasma pneumoniae.The bacterial pathogen is mainly Streptococcus pneumoniae.High fever, faster breathing, and cyanosis around the mouth are risk factors for severe pneumonia.Multi-pathogen mixed infection is prone to serious complications.

ABSTRACT

Objective To investigate the effect of butylphthalide (NBP) on H2S content and the expression of NR2B in the hippocampus of alcohol dependence rats. Methods A total of 84 SD male rats were randomly divided into 6 groups. Except for the normal group, other groups were subjected to alcohol solution with concentration of 6% ( V/V) for 28 d. Drug intervention began at the 14th day,and rats in the low,medium,high dose group were treated with NBP with a different concentration. Erden abstinence scoring was used to evaluate the rats withdrawal symptom. H2S content was measured in one side of hippocampus and CBS activity was tested in the other side of hippocampus. Hippocampus of 3 rats from each group was used to investigate NR2B mRNA level. Results Withdrawal symptom score ( 12.27 ± 1. 19),H2S content(30. 25 ±8.82), CBS activity (72. 44 ±7. 46) and NR2B mRNA expression( 19. 47 ±0. 86) in medium dose NBP group rats were lower than withdrawal symptom score(14.09 ±2.21) ,H2S content(44. 50 ±6. 65) , CBS activity(79. 06 ±4. 57) and NR2B mRNA expression (29. 13 ±1.39) in experimental control group (P<0.05). Withdrawal symptom score(12. 18 ±1.08) ,H2S content(33.00 ±5.38) ,CBS activity(67. 81 ±9. 37) and NR2B mRNA expression(23. 12 ± 1. 86) in high dose NBP group rats were lower than experimental control group (P < 0. 05). Conclusion NBP can reduce withdrawal symptoms of alcohol dependence rats,may be related to decreased expression of H2S/CBS system, and NR2B mRNA expression.
