RESUMEN

Alzheimer's disease (AD) is a growing concern in modern society, and there is currently a lack of effective therapeutic drugs. Sagacious Confucius' Pillow Elixir (SCPE) has been studied for the treatment of neurodegenerative diseases such as AD. This study aimed to reveal the key components and mechanisms of SCPE's anti-AD effect by combining Ultra-high Performance Liquid Chromatography-electrostatic field Orbitrap combined high-resolution Mass Spectrometry (UPLC-LTQ/Orbitrap-MS) with a network pharmacology approach. And the mechanism was verified by in vivo experiments. Based on UPLC-LTQ/Orbitrap-MS technique identified 9 blood components from rat serum containing SCPE, corresponding to 113 anti-AD targets, and 15 of the 113 targets had high connectivity. KEGG pathway enrichment analysis showed that estrogen signaling pathway and synaptic signaling pathway were the most significantly enriched pathways in SCPE anti-AD, which has been proved by in vivo experiments. SCPE can exert estrogenic effects in the brain by increasing the amount of estrogen in the brain and the expression of ERα receptors. SCPE can enhance the synaptic structure plasticity by promoting the release of brain-derived neurotrophic factor (BDNF) secretion and improving actin polymerization and coordinates cofilin activity. In addition, SCPE also enhances synaptic functional plasticity by increasing the density of postsynaptic densified 95 (PSD95) proteins and the expression of functional receptor AMPA. SCPE is effective for treatment of AD and the mechanism is related to increasing estrogenic effects and improving synaptic plasticity. Our study revealed the synergistic effect of SCPE at the system level and showed that SCPE exhibits anti-AD effects in a multi-component, multi-target and multi-pathway manner. All these provide experimental support for the clinical application and drug development of SCPE in the prevention and treatment of AD.

RESUMEN

This study intended to explore the effect and mechanism of total flavonoids of Drynariae Rhizoma in improving scopola-mine-induced learning and memory impairments in model mice. Ninety four-month-old Kunming(KM) mice were randomly divided into six groups. The ones in the model group and blank group were treated with intragastric administration of normal saline, while those in the medication groups separately received the total flavonoids of Drynariae Rhizoma, Kangnaoshuai Capsules, donepezil, as well as total flavonoids of Rhizoma Drynariae plus estrogen receptor(ER) blocker by gavage. The mouse model of learning and memory impairments was established via intraperitoneal injection of scopolamine. Following the measurement of mouse learning and memory abilities in Morris water maze test, the hippocampal ERß expression was detected by immunohistochemistry, and the expression levels of ERß and phosphorylated p38(p-p38) in the hippocampus and B-cell lymphoma 2(Bcl-2), Bcl-2-associated death promoter(Bad), and cysteinyl aspartate-specific protease-3(caspase-3) in the apoptotic system were assayed by Western blot. The contents of malondia-ldehyde(MDA), superoxide dismutase(SOD), and nitric oxide(NO) in the hippocampus were then determined using corresponding kits. Compared with the control group, the model group exhibited significantly prolonged incubation period, reduced frequency of cros-sing the platform, shortened residence time in the target quadrant, lowered ERß, Bcl-2 and SOD activity in the hippocampus, and increased p-p38/p38, Bad, caspase-3, MDA, and NO. Compared with the model group, the total flavonoids of Rhizoma Drynariae increased the expression of ERß and SOD in the hippocampus, down-regulated the expression of neuronal pro-apoptotic proteins, up-re-gulated the expression of anti-apoptotic proteins, and reduced p-p38/p38, MDA, and NO. The effects of total flavonoids of Drynariae Rhizoma on the above indexes were reversed by ER blocker. It has been proved that the total flavonoids of Drynariae Rhizoma obviously alleviate scopolamine-induced learning and memory impairments in mice, which may be achieved by regulating the neuronal apoptotic system and oxidative stress via the ER-p38 mitogen-activated protein kinase(ER-p38 MAPK) signaling pathway.

RESUMEN

BACKGROUND: To address the feasibility and advantages of subxiphoid uniportal video-assisted thoracoscopic surgery (VATS) for lobectomy. METHODS: Since August 2014, 105 cases of subxiphoid uniportal VATS lobectomy were successfully performed. The clinical information was retrospectively analyzed. RESULTS: 96 cases underwent unilateral operation and 9 underwent bilateral operations. Surgeries were successfully performed with a complication rate of 10.5%. The average pain scores 8 hours, day 1, 2 and 3 after surgery, as well as the day before discharge were 2.39±0.99, 2.06±0.85, 1.68±0.87, 1.29±0.78, and 0.48±0.51, respectively, which were significantly lower than those in the control group (standard intercostal uniportal VATS) (P<0.001). CONCLUSIONS: The subxiphoid uniportal VATS lobectomy is safe and reliable, which is appropriate for bilateral lung diseases, and significantly relieves postoperative incision pain.

RESUMEN

Genome-wide association studies have identified two SNPs (rs402710 and rs401681) of CLPTM1L at chromosome 5p15.33 as a new lung cancer (LC) susceptibility locus in populations of European descent. Since then, the relationship between these SNPs and LC has been reported in various ethnic groups; however, these studies have yielded inconsistent results. To investigate this inconsistency, we performed a meta-analysis of 27 studies involving a total of 60,828 cases and 109,135 controls for the two polymorphisms to evaluate its effect on genetic susceptibility for LC. An overall random-effects per-allele odds ratio of 1.14 (95% CI 1.11-1.16, P < 10(-5)) and 1.15 (95% CI 1.12-1.19, P < 10(-5)) was found for the rs401681 and rs402710 polymorphism, respectively. Significant results were also observed for under dominant and recessive genetic models. After stratified by ethnicity, significant associations were found among Caucasians and East Asians. In the subgroup analysis by sample size, significantly increased risks were found for these polymorphisms in all genetic models. In addition, we find both rs402710 and rs401681 conferred significantly greater risks for adenocarcinoma and squamous cell carcinoma when stratified by histological type of tumors. Furthermore, associations of these polymorphisms with LC risk were observed among current smokers and former smokers, as well as never smokers. Our findings demonstrated that rs402710 and rs401681 are risk-conferring factors for the development of lung cancer.
