Chemical Constituents from the Heartwood of Solanum Verbascifolium L. And Their Anti-Inflammatory Activities Combined Network Pharmacology.

Phytochemical studies on 95 % ethanol extract of the heartwood of Solanum verbascifolium L. resulted in the isolation of one new amide derivative (1), and 21 known phenylpropanoids compounds. The structures were characterized by spectral analysis and high-resolution mass spectrometric analysis. The anti-inflammatory activity of amide compounds 1-4 and 6-9 by investigating their impact on the release of nitric oxide (NO) in MH-S cells. Our findings unveiled significant inhibitory effects on NO secretion. Compound 1 exhibited robust dose-dependent suppression, with pronounced inhibition observed at both 20 µM (P<0.01) and 40 µM (P<0.01). Furthermore, compound 9 demonstrated noteworthy inhibitory effects at 40 µM (P<0.01). Similarly, compounds 3 and 4 displayed substantial inhibition of NO secretion at the same concentration, although the significance level was slightly lower (P<0.05). It is expected that there is a substantial association between the anti-inflammatory activities of amides and their targets, specifically PTGS2, by combining network pharmacology and molecular docking techniques. This discovery emphasizes amides' potential as an interesting subject for additional study in the realm of anti-inflammatory medications.

The role of lactate deshydrogenase levels on non-small cell lung cancer prognosis: a meta-analysis.

The role of serum lactate dehydrogenase (LDH) on the clinical outcomes of non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs) treatment remained to be elucidated. Therefore, we did this meta-analysis. We searched databases including PubMed, EMBASE, and Cochrane Library till to June, 2017. The relationships between the LDH levels and overall survival (OS) and progression free survival (PFS) were assessed by calculating hazard ratios (HRs) and 95% confidence intervals (CIs). The association between the LDH levels and disease control rate (DCR) was calculated by odds ratio (OR) and 95% CI. Seven studies were included in the meta-analysis. As for DCR, the result from this meta-analysis was not positive (OR=0.71; 95% CI 0.21 - 2.37; P=0.57). As for PFS, the result of the meta-analysis indicated that elevated LDH was significantly associated with shorter PFS (HR=1.88; 95%CI, 1.37-2.59). When studies were stratified by ethnicity, significant association was also observed in Asian group (HR=2.36; 95%CI, 1.57-3.55). As for OS, patients with high levels of LDH showed significantly shorter OS (HR=2.44; 95%CI, 1.84-3.23). In the subgroup by race, significant associations were found in Asian group (HR=2.62; 95%CI, 1.61-4.26) and Caucasian population (HR=2.36; 95%CI, 1.66-3.34). In conclusion, this meta-analysis suggested that elevated LDH level was associated with the poor PFS and OS of NSCLC patients receiving EGFR-TKIs treatment.

17q21 locus rs7216389 polymorphism and childhood asthma risk: a meta-analysis.

INTRODUCTION: Recently, a genome-wide association study (GWAS) indicated that rs7216389 polymorphism on chromosome 17q21 was associated with paediatric asthma risk. However, the results remained controversial. Therefore, a meta-analysis was performed. EVIDENCE ACQUISITION: A comprehensive literature retrieve was performed on PubMed, Embase and Science Direct databases up to Feb 20, 2016. The strength of association between 17q21 locus rs7216389 polymorphism and pediatric asthma risk was assessed by computing odds ratio (OR) with its corresponding 95% confidence interval (CI). EVIDENCE SYNTHESIS: A total of 10 studies with 7797 cases and 38757 controls were included. A statistically significant association of rs7216389 polymorphism and pediatric asthma risk was found (OR=1.41, 95%CI=1.34-1.49, P<0.00001). Furthermore, both Caucasians (OR=1.41, 95%CI=1.33-1.49, P<0.00001) and Asians (OR=1.43, 95%CI=1.25-1.63, P<0.00001) with rs7216389 polymorphism showed significant association, respectively. A significantly increased susceptibility was identified in atopic asthma (OR=1.45, 95%CI=1.22-1.72, P<0.00001). In the stratification analysis by study design, both case-control studies (OR=1.40, 95%CI=1.33-1.48, P<0.00001) and cohort studies (OR=2.05, 95%CI=1.32-3.17, P=0.001) showed significant association, respectively. CONCLUSIONS: In conclusion, this meta-analysis suggests that 17q21 locus rs7216389 polymorphism was significantly associated with paediatric asthma risk.

Asthma and the risk of lung cancer: a meta-analysis.

Some studies found that there was a significant association between asthma and the risk of lung cancer. However, the results are inconclusive. Therefore, we performed a meta-analysis. We searched the electronic databases for all relevant articles. Odds ratio (OR) with 95% confidence interval (CI) were used to calculate the strength of the association between asthma and lung cancer risk. Asthma was significantly associated with the increased risk of lung cancer (OR = 1.44; 95% CI 1.31-1.59; P < 0.00001; I2 = 83%). Additionally, asthma patients without smoking also had the increased lung cancer risk. In the subgroup analysis of race and gender, Caucasians, Asians, male, and female patients with asthma showed the increased risk of lung cancer. However, asthma was not significantly associated with lung adenocarcinoma risk. In the stratified analysis by asthma definition, significant associations were found between asthma and lung cancer in self-reported subgroup, questionnaire subgroup, and register databases subgroup. However, no significant association was observed in physician-diagnosed asthma subgroup. In conclusion, this meta-analysis suggested that asthma might be significantly associated with lung cancer risk.
