Asthma is a chronic inflammatory disorder of the airways. Schisandrin B (SB) is the main effective component. This study investigated the effects of SB on airway inflammation and airway remodeling in asthma. The rat model of asthma was established. The rats were treated with SB to evaluate the effects of SB on airway inflammation, airway remodeling, NLRP3 inflammasome activation, and pyroptosis. Alveolar macrophages of rats were isolated, and the macrophage inflammatory model was established by lipopolysaccharide (LPS) induction. The LPS-induced macrophages were treated with SB. The binding relationship between miR-135a-5p and TPRC1 was analyzed. LPS + SB-treated macrophages were transfected with miR-135a-5p inhibitor. The expressions of key factors of the STAT3/NF-κB pathway were detected. SB reduced airway inflammation and airway remodeling in asthmatic rats. SB inhibited NLRP3 inflammasome activation and reduced pyroptosis in asthmatic rats and LPS-induced macrophages. Linsitinib ic50 SB reversely regulated the miR-135a-5p/TRPC1 axis. Downregulation of miR-135a-5p attenuated the inhibitory effect of SB on NLRP3 inflammasome activation. SB inhibited the STAT3/NF-κB pathway via the miR-135a-5p/TRPC1 axis. In conclusion, SB inhibited NLRP3 inflammasome activation and reduced pyroptosis via the miR-135a-5p/TRPC1/STAT3/NF-κB axis, thus alleviating airway inflammation and airway remodeling in asthma. This study may confer novel insights for the management of asthma.

This systematic review aimed to comprehensively collect and summarise the current body of knowledge regarding the cost-of-illness of amyotrophic lateral sclerosis, to identify cost-driving factors of the disease and to consider the development of costs over the course of disease. Further, the review sought to assess the methodological quality of the selected studies.

A systematic review was performed using the databases MEDLINE, Embase, Cochrane Library and PsycINFO. Studies examining the economic burden of amyotrophic lateral sclerosis on a patient or national level written in English or German published from the year 2001 onwards were included. Additional searches were conducted. Study characteristics and results were extracted and compared.

In summary, 20 studies were included in this review. Most studies investigated costs per patient, amounting to total costs between €9741€ to €114,605. Six studies confirmed a rise in costs with disease progression, peaking close to the death of a patient. National costs for amyotrophic lateral sclerosis varied between €149 million and €1329 million.

Most of these studies suggest the economic burden of amyotrophic lateral sclerosis to be considerable. However, further research is needed to establish a cost-effective health policy in consideration of disease severities.

Patients with neurofibromatosis type-1 (NF-1) and associated plexiform neurofibromas (PNs) often have a high burden of illness owing to debilitating symptoms of these tumors and limited management options. To investigate this complex disease, a systematic literature review (SLR) was conducted on the epidemiology of pediatric NF-1 and associated PNs, the burden of illness, and outcomes of surgical resection of these tumors.

Searches of MEDLINE and Embase (from database inception to October 2019) and conference proceedings (2017-2019) were performed to identify relevant studies. The review methodology was informed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines.

Twenty studies were identified. Evidence confirmed NF-1 is rare but that occurrence may differ geographically. Only limited data on the birth incidence of NF-1 were identified. Prevalence estimates for pediatric NF-1 varied from one per 960 individuals (aged 17years) to one per 5681 children (aged < 16years) across five large registry/surveillance studies (each involving > 19,000 individuals). The prevalence of associated PNs was 0-29.6%. PNs carried increased mortality risk in pediatric NF-1 in both studies that explored this potential association. Patients with PNs reported high use of analgesics. The complication rate post-surgery for PNs was around 17-19%. The recurrence rate (18-68%) was dependent on the extent of excision achieved during surgery.

Data suggest NF-1 is a rare disease with increased morbidity and mortality in children with associated PNs. Surgical outcomes for PNs are often poor. These findings suggest significant unmet needs in patients with NF-1-associated PNs.

Myasthenia gravis (MG) is a potentially fatal neuromuscular disorder if left untreated. In this study, we tried to address the possible demographic, clinical, and laboratory determinants of severity and outcome in Iranian MG patients over a follow-up period of more than 5years.

Demographic and diagnostic data (age, age of onset, antibody status, thymus pathology, and duration of the disease) of the patients with MG were extracted. Maximal disease severity and post-intervention status were assessed according to the recommendations of the task force of the Myasthenia Gravis Foundation of America.

In our series of 146 patients, MG was more severe in older, anti-muscle specific tyrosine kinase (MuSK) positive, and thymomatous patients. Seropositivity to the MuSK antibody and the presence of thymoma determined the need for immunosuppressive drugs. However, the number of patients requiring more than one immunosuppressive was not significantly different among various subtypes.

The overall outcome was favorable in the majority of patients, despite differences in the disease course and severity. In contrary to the previous reports, anti-MuSK positive patients in our series did not need a more vigorous treatment regimen comparing other serologic subtypes of MG.
