Correspondence analysis was used for determining the important factors from the six factors influencing analysis of cephalosporin in reversed phase-high performance liquid chromatography (RP-HPLC). Experiments were planed by U7(76), then the synthetical correspondence between a series of optimizations and the factors was calculated. Result indicated that that proportion of organic solvent, pH and concentration of buffer were three most important factors. It showed that the correspondence analysis was a better method to determining the important factors in RP-HPLC

Objective To explore the treatment of children with EB virus infection accompanied by facial paralysis. Method The clinical data of a child with EB virus infection accompanied by facial paralysis was analyzed retrospectively, and the related literature were reviewed. Results A 2-year-old boy was admitted to hospital due to fever and mouth askew for 4 days. After admission, he was confirmed to have EB virus infection and viremia by serology and polymerase chain reaction, and then treated with acyclovir. The symptoms of facial paralysis and EB viremia disappeared completely 14 days after antiviral treatment. There was no recurrence in the short-term follow-up. Interestingly, the literature analysis shows that there is still limited evidence for the antiviral treatment by acyclovir in children with acute infection of EB virus associated with facial paralysis. Conclusion Antiviral treatment may be beneficial to EB viremia with facial paralysis.

Objective To investigate the effect of FK506 on the expression of TNF -? mRNA in isolated liver with reperfusion. Methods After the model of isolated liver with reperfusion was set upp,the expression of TNF-? mRNA was detected with RT-PCR in different preservation time of the isolated liver. Results In FK506-treated group, expression level of TNF-? mRNA was obviously lower(P

Objective:To analyze the clinical characteristics of plastic bronchitis(PB) caused by adenoviral pneumonia.Methods:The clinical data of 9 children diagnosed with PB caused by adenoviral pneumonia in the Xiamen Children′s Hospital from March to June 2019 were retrospectively analyzed.Results:Among the 9 children(3 boys and 6 girls), 6 patients were under 2 years old.All patients had fever, cough and dyspnea, with the duration of 6-15 days.Laboratory tests showed that procalcitonin(PCT) and increased in 7 children, D-dimer, fibrinogen degraded product (FDP) were increased in 6 children, and lactate dehydrogenase(LDH) was increased in 8 children.Chest imaging examination showed atelectasis with pulmonary consolidation in 9 children, including 4 cases of left lower lobe consolidation, 2 cases of right lower lobe consolidation, 1 case of right upper lung consolidation, and 2 cases of consolidation of multiple lungs in the lower lobe.Seven cases had pleural effusion.By fiberoptic bronchoscopy, the bronchial plastics was removed from the left lower lobe in 5 patients, from the right lower lobe in 3 patients, and from the right upper lobe in 1 patient on the 6th to 20 th day of the disease.Eight patients were discharged after clinical cure.One patient deve-loped multiple organ failure, and discharged from the hospital after the family members gave up rescue.The death was reported by the telephone follow-up death. Conclusions:PB is considered when patients with adenovirus pneumonia have persistent high fever, shortness of breath, dyspnea, pulmonary consolidation/lung atelectasis, increased PCT and LDH, hypercoagulability of the blood, and pleural effusion.Fiberoptic bronchoscopy plays an important role in confirming the diagnosis and improving the prognosis.
