Objective:To observe the clinical efficacy of Xinyue Decoction combined with fluoxetine hydrochloride in the treatment of cognitive impairment of senile depression.Methods:A randomized controlled trial study was conducted. Totally 116 elderly patients with depression accompanied by cognitive impairment were set as observation subjects, and were divided into a control group and an experimental group using random number table method, with 58 patients in each. The control group received treatment with fluoxetine hydrochloride capsules, while the experimental group was administered Xinyue Decoction Granules in addition to the treatment regimen of the control group. The treatment lasted for 8 weeks for both groups. Comparison was made between the two groups regarding the changes in TCM syndrome scores. Hamilton Depression Scale (HAMD-24) was used to assess the degree of depression, and Montreal Cognitive Assessment (MoCA BJ) was used to assess cognitive ability; the serum levels of brain-derived neurotrophic factor (BDNF), IL-1β, IL-6 and TNF-α were detected by ELISA; the adverse reactions during treatment were observed and recorded, and the clinical efficacy was evaluated.Results:The total effective rate of TCM syndromes was 90.4% (47/52) in the experimental group and 75.5% (40/53) in the control group, with statistical significance ( χ2=4.11, P<0.05); the total effective rate of MoCA-BJ was 76.9% (40/52) in the experimental group and 58.5% (31/53) in the control group, with statistical significance ( χ2=4.61, P<0.05); the total effective rate of HAMD-24 was 88.5% (46/52) in the experimental group and 71.7% (38/53) in the control group, with statistical significance ( χ2=4.07, P<0.05). After treatment, the TCM syndrome score, HAMD-24 and MoCA-BJ scores of the experimental group were lower than those in the control group ( t=-3.51, -5.11, 2.39, P<0.01 or P<0.05); the level of serum BDNF [(10.49±1.76) ng/L vs. (9.61±1.85) ng/L, t=2.28] in the observation group was higher than that of the control group ( P<0.05), and the levels of IL-1β, IL-6 and TNF-α were lower than those in the control group ( t=-2.50, -2.46, -2.18, P<0.05). During the treatment, the incidence of adverse reactions was 5.77% (3/52) in the experimental group and 7.55% (4/53) in the control group, without statistical significance ( χ2=0.13, P>0.05). Conclusion:Xinyue Decoction combined with fluoxetine hydrochloride can reduce the degree of depression in elderly patients with cognitive impairment of depression, improve the cognitive ability of patients and clinical efficacy.

OBJECTIVES: Non-small cell lung cancer (NSCLC) accounts for 85% of all lung cancer, with highmorbidity and mortality rate. Nove drug development for NSCLC is urgently needed.This study aims to investigate the activity of lathyrol derivatives and the mechanism for its inhibitory effect on the growth of NSCLC cells. METHODS: Three lathyrol derivatives were synthesized from lathyrol and their structures were verified by nuclear magnetic resonance. MTT assay was used to detect the effects of the lathyrol derivatives on the proliferation activity of NSCLC cells (A549 and H1299 cells), and the compound with the best activity was selected for subsequent experiments. Colony forming assay, wound-healing assay, and transwell assay were applied to detect in vitro cell proliferation, migration and invasion ability in A549 and H1299 cells, respectively. Quantitative real-time RT-PCR and Western blotting were performed to detect mRNA and protein levels of E-cadherin, N-cadherin, β-catenin, and MMP2 in A549 cells, respectively. RESULTS: Three lathyrol derivatives inhibited the growth of A549 and H1299 cells in a dose-dependent manner, and they showed a weak inhibitory effect on normal cells Beas-2B and 16HBE, indicating that they possessed certain selective toxic effects. Therefore, C-5 benzoylated lathyrol with the best activity was selected as the ideal drug for the subsequent experiments. Compared with the control group, the number and size of cell clusters in the treatment group of A549 and H1299 cells were significantly decreased, the relative mobility were significantly decreased, and the number of invaded cells were significantly decreased (all P<0.05), indicating that the in vitro cell proliferation, migration and invasion ability were decreased. The mRNA levels of integrin α2, integrin β1, MMP2, MMP9, β-catenin, and N-cadherin were decreased, while the expression of E-cadherin was increased (all P<0.05). The protein levels of N-cadherin, β-catenin, MMP2, and integrin αV were decreased, while the expression of E-cadherin was increased (all P<0.05). CONCLUSIONS The lathyrol derivatives synthesized in this study possess good inhibitory activity against NSCLC. Among them, C-5 benzoylated lathyrol significantly inhibits the proliferation, migration, and invasion ability of NSCLC cells in vitro through regulating the process of epithelial-mesenchymal transition.
