1.Negative pressure pulmonary edema
International Journal of Pediatrics 2014;41(2):167-169
Negative pressure pulmonary edema is a common pediatric disease,but also often to be ignored,which occurs from the upper airway obstruction caused by the change in the absolute value of negative intrathoracic pressure increase,resulting in a corresponding respiratory physiology,hemodynamic changes,common causes include laryngitis,whooping cough,foreign body,such as obstructive sleep apnea.Therefore,it is important to know the common causes of negative pressure pulmonary edema and to treat the patients in time.
2.Progress in the treatment of respiratory virus infection in children
International Journal of Pediatrics 2021;48(1):43-46
Respiratory virus remains to be an important pathogen of respiratory disease in children.The disease can occur in all age groups, especially in young children.Most viral infections have a good prognosis, but special viruses still cause great harm to the health of children.Respiratory viral therapy includes symptomatic therapy, broad-spectrum antiviral drugs, drugs that directly target the viral replication cycle, drugs that attenuate the inflammatory response, and anti-viral nanodrugs.New antiviral drugs are urgently needed to develop.The repurposing of the existing therapeutic agents previously designed for other virus infections is also an effective way.The treatment of respiratory virus infection has become an important topic in clinical research.

Journal of Medical Postgraduates 2014;(4):394-397
Objective Intranasal drops of dexmedetomidine can induce conscious sedation in children .This study was to com-pare the sedative effects of different doses of intranasal dexmedetomidine in different age groups of children patients . Methods We e-qually randomized 90 hernia children waiting for elective unilateral inguinal surgery ( ASAⅠ-Ⅱ) to groupsⅠ,ⅡandⅢ.At 35 minutes be-fore surgery, we obtained the heart rate (HR), mean artery pressure (MAP) of all the patients.The children in groupsⅠandⅡreceived nasal instillation of dexmedetomidine at 1 and 2μg/kg respectively, while those in groupⅢ0.4 mL of normal saline, followed by sevoflu-rane induction, intravenous injection of sufentanil (0.2μg/kg), and laryngeal mask airway anesthesia with sevoflurane .We recorded HR, MAP before medication, at 10 min, 20 min and 30 min before mediation, right after surgery, and at the recovery to consciousness . We also recorded the sedation onset time and post-surgery recovery time and assessed sedation satisfaction using the Ramsay score . Results The rates of satisfactory preoperative sedation were 50 and 63% in groupsⅠandⅡ, significantly higher than 10%in groupⅢ(P<0.05). In the 1-4-year group, the sedation satisfaction rate , sedation onset
time and post-surgery recovery time showed no significant differences between groupsⅠandⅡ(P>0.05).In the 5-8-year group, seda-tion satisfaction rate was markedly higher in groupⅡthan in groupsⅢ(77%vs 22%, P<0.05) andⅠ(77%vs 45%) . Conclusion At 1 and 2μg/kg, intranasal drops of dexmedetomidine produces similar rates of satisfactory sedation in children aged 1-4 years, and at 2μg/kg can achieve an even higher rate of satisfactory sedation without adverse hemodynamic effects in those aged 5-8 years.

Objective To investigate the effect of electroacupuncture on expression of growth associated protein-43 (GAP-43) and Nogo-A in brain after focal cerebral ischemia/reperfusion in rats. Methods 48 male Sprague-Dawley rats were randomly divided into sham group, model group and electroacupuncture group, and the latter two were modeled as middle cerebral artery occlusion and reperfusion with nylon monofilament suture. Electroacupuncture was performed 90 min after modeling in the electroacupucture group at acupoints of Neiguan (PC06), Shuigou (DU26), Sanyinjiao (SP06), Baihui (DU20), for 30 min, once a day. The sham group and the model group were conventionally fed in cages without any intervention. 8 rats of each group were assessed with Longa's score, and the expressions of GAP-43 and Nogo-A were detected with immunohistochemistry 7 d and 14 d after modeling respectively. Results The sham group presented no neurological symptoms. There was not different in Longa's score between the model group and the electroacupuncture group 7 d after modeling (P>0.05), but was different 14 d after modeling (P<0.05). GAP-43 positive cells was not found in the sham group, but could be found around cerebral ischemia 7 d after modeling, which decreased 14 d after modeling in the model group. GAP-43 positive cells increased significantly in the electroacupuncture group compared with the model group at each time (P<0.01). Nogo-A positive cells was few found in the sham group, and was more in the model group (P<0.01). The expression of Nogo-A decreased significantly in the electroacupuncture group compared with the model group at each time (P<0.01). Conclusion Electroacupuncture can improve neurological function of focal cerebral ischemia/reperfusion rats, which may be associated with the increase of GAP-43 and descrease of Nogo-A in peri-infarct regions

Objective To compare the efficacy of combination therapy of intravenous immunoglobulin (IVIG) and corticosteroids versus corticosteroids alone in the treatment of toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS). Methods A retrospective study was conducted. Totally, 65 consecutive patients diagnosed as either TEN or SJS from January 1993 to October 2007 were included in this study. For 45 patients collected from 1993 to 2000, including 35 cases of TEN and 10 cases of SJS, methylprednisolone of 1 - i.5 mg per kilogram bodyweight per day or equivalent hydrocortisone or dexamethasone was given; for the remaining 20 patients collected from 2001 to 2007, including 12 cases of based on SCORTEN, a severity-of-illness-score system for TEN/SJS prognosis. Results Among the 45 patients treated with corticosteroids alone, 8.63 patients were expected to die based on SCORTEN system, while 10 deaths were observed. Standardized mortality ratio (SMR) analysis revealed that the patients treated with corticosteroids alone were 16% more likely to die than those treated with routine therapy (SMR = 1.16; 95% confidence interval, 0.56 - 2.13). In the remaining 20 patients who received combination therapy, 3 deaths occurred, while 3.51 deaths were expected based on the SCORTEN system. SMR analysis showed that the combination therapy had a trend to reduce the mortality rate of TEN/SJS (SMR = 0.85; 95% confidence interval, 0.18 - 2.50). No significant difference was noted in the mortality rate of TEN/SJS between the combination therapy and corticosteroid monotherapy (16.7% vs 22.8% in TEN, 12.5% vs 20% in SJS, respectively, both P > 0.05). In patients with TEN, the combination therapy significantly reduced the time to arrest disease progression (4.30 ± 2.36 days vs 7.15 ± 3.35 days, t = 2.46, P < 0.05) and total hospitalized time (23.40 ± 5.10 days vs 34.30 ± 16.00 days, t = 3.14, P < 0.05), but had no significant effect on the time to taper corticosteroid dose (12.30 ± 3.10 days vs 12.20 ± 5.13 days, t = -0.045, P > 0.05) compared with the corticosteroid monotherapy did; so was the case for SJS. Conelusious Compared withsolo administration of corticosteroids, the combination therapy with corticosteroid and IVIG seems to reducethe mortality rate of TEN/SJS. Also, the combination therapy could arrest the progression of TEN/SJS earlier accompanied by a decrease in hospitalization time. However, the time period of corticosteroid tapering is not shortened by the combination therapy.
