RESUMO
OBJECTIVE: This study investigated the effects of N-Acetylcysteine (NAC) combined with Ambroxol Hydrochloride (AH) on clinical symptoms, C-Reactive Protein (CRP), and Procalcitonin (PCT) levels in children with pneumonia. METHODS: A total of 98 children with pneumonia were assigned to the control group and observation group by random number table method. NAC was administered to the observation group and AH was given to the control group. The therapeutic effect was observed, the disappearance time of clinical symptoms and levels of inflammatory factors, lung function parameters, blood gas analysis parameters, and immunoglobulin were measured. The incidence of adverse reactions was statistically analyzed. RESULTS: A higher effective rate was observed in the observation group than in the control group (p < 0.05). Antipyretic time, cough disappearance time, and lung rale disappearance time in the observation group were shorter than those in the control group (p < 0.05). After treatment, CRP and PCT were lower (p < 0.05), FVC, FEV1, and FEV1/FVC were higher, PaCO2 was lower, PaO2 and SaO2 were higher, and IgA, IgG, IgM, and C3 were higher in the observation group than those in the control group (p < 0.05). The incidence of adverse reactions between the two groups was not significantly different (p > 0.05). CONCLUSION: NAC combined with AH is effective in the treatment of pediatric pneumonia by effectively alleviating clinical symptoms, reducing inflammatory factors, and improving lung function and immune function.

RESUMO
Background and Purpose- Inhibition of brain NKCC1 (Na+-K+-Cl- cotransporter 1) with bumetanide (BMT) is of interest in ischemic stroke therapy. However, its poor brain penetration limits the application. In this study, we investigated the efficacy of 2 novel NKCC1 inhibitors, a lipophilic BMT prodrug STS5 (2-(Dimethylamino)ethyl 3-(butylamino)-4-phenoxy-5-sulfamoyl-benzoate;hydrochloride) and a novel NKCC1 inhibitor STS66 (3-(Butylamino)-2-phenoxy-5-[(2,2,2-trifluoroethylamino)methyl]benzenesulfonamide), on reducing ischemic brain injury. Methods- Large-vessel transient ischemic stroke in normotensive C57BL/6J mice was induced with 50-min occlusion of the middle cerebral artery and reperfusion. Focal, permanent ischemic stroke in angiotensin II (Ang II)-induced hypertensive C57BL/6J mice was induced by permanent occlusion of distal branches of middle cerebral artery. A total of 206 mice were randomly assigned to receive vehicle DMSO, BMT, STS5, or STS66. Results- Poststroke BMT, STS5, or STS66 treatment significantly decreased infarct volume and cerebral swelling by ≈40% to 50% in normotensive mice after transient middle cerebral artery occlusion, but STS66-treated mice displayed better survival and sensorimotor functional recovery. STS5 treatment increased the mortality. Ang II-induced hypertensive mice exhibited increased phosphorylatory activation of SPAK (Ste20-related proline alanine-rich kinase) and NKCC1, as well as worsened infarct and neurological deficit after permanent distal middle cerebral artery occlusion. Conclusions- The novel NKCC1 inhibitor STS66 is superior to BMT and STS5 in reducing ischemic infarction, swelling, and neurological deficits in large-vessel transient ischemic stroke, as well as in permanent focal ischemic stroke with hypertension comorbidity.
