Background. Traditional Chinese herbal medicine was associated with improved prognosis in patients with performance score 0-1 at the time of diagnosis of stage IV pulmonary adenocarcinoma (PAC) treated with platinum-based chemotherapy (PBT). Objective. The authors investigated the effect of 1- to 4-month lag time to traditional Chinese medicine (TCM) treatment on the median and 1-year survival of PBT-PAC patients. Methods. The median lag time to treatment was 3 months. In the first 3 months, about 35% of the patients died, but thereafter the survival curve flattened off and the death of the next 35% to 40% of patients took 9 months. Leaving out patients with lag time up to 3 months therefore would be a reasonable choice. To be on the safe side, the effects of leaving out patients up to 4 months were investigated. The Kaplan-Meier survival curves were used. Results. The median and 1-year survival of the PBT-PAC patients was 5.0 months and 27%, respectively. Leaving out patients with 0-1 month follow-up, 0-2, 0-3, and 0-4 months follow-up changed the median and 1-year survival, respectively, to 5.5 months and 32%, 6.5 months and 36%, 9.0 months and 43%, and 10.0 months and 52%. The median survival of PBT + TCM in PAC patients was 22.6 months and 78%. Median lag time to TCM treatment was 3.0 months. With up to 4 months lag time to treatment due to combined patients' and TCM doctor's waiting time, the improved survival of PBT + TCM performance score 0-1 (fully ambulant) patients at the time of diagnosis still is significant (P <.01, hazard ratio = 0.51). Moreover, the survival of patients treated by TCM doctors with little or more months lag time to treatment was not different (P =.79). Conclusion. Increasing lag time to treatment up to 4 months improves the median and 1-year survival of PBT patients without TCM but is unlikely to explain the greatly improved prognosis of PBT + TCM treated patients with fully ambulant stage IV PAC. © SAGE Publications 2011.

2-Methoxyestradiol (2-ME) reduces atherosclerotic lesion formation. However, the underlying mechanisms remain largely unknown. In this work, we investigated the effect of 2-ME on monocyte adhesion to vascular endothelial cells. Lipopolysaccharides (LPS) greatly increased the attachment of monocyte onto cultured human umbilical vascular endothelial cells (HUVECs), which was inhibited by 2-ME in a dose- and time-dependent manner, or by the vascular cell adhesion protein-1 (VCAM-1) neutralizing antibody, suggesting that a functional releationship between 2-ME and VCAM-1 may exist. In accordance with this, treatment with 2-ME (10− 7–10− 5 M) for 6–48 h downregulated VCAM-1 protein expression. Meanwhile, the nuclear factor κB (NF-κB) p65 subunit activity and its nuclear translocation was inhibited by 2-ME in HUVECs. The PI3K inhibitor wortmannin or the specific Akt siRNA both inhibited the effects of 2-ME, suggesting that 2-ME inhibited p65 activity via PI3K/Akt signaling. In conclusion, 2-ME inhibits VCAM-1 expression and thus prevents monocyte adhesion to vascular endothelial cells via regulation of PI3K/Akt and NF-κB signaling. These findings will be helpful for better understanding the mechanisms through which 2-ME improves endothelial function. © 2016 Taylor & Francis.

Traditional Chinese medicine (TCM) syndrome is an important basis for TCM diagnosis and treatment. As Child-Pugh classification as well as compensation and decompensation phase in liver cirrhosis, it is also an underlying clinical classification. In this paper, we investigated the correlation between single nucleotide polymorphisms (SNPs) of Interleukin-10 (IL-10) and TCM syndromes in patients with hepatitis B cirrhosis (HBC). Samples were obtained from 343 HBC patients in China. Three SNPs of IL-10 (592A/C, 819C/T, and 1082A/G) were detected with polymerase chain-reaction-ligase detection reaction (PCR-LDR). The result showed the SNP-819C/T was significantly correlated with Deficiency syndrome (P = 0.031), but none of the 3 loci showed correlation either with Child-Pugh classification and phase in HBC patients. The logistic regression analysis showed that the Excess syndrome was associated with dizzy and spider nevus, and the Deficiency syndrome was associated with dry eyes, aversion to cold, IL-10-819C/T loci, and IL-10-1082A/G loci. The odds ratio (OR) value at IL-10-819C/T was 4.022. The research results suggested that IL-10-819C/T locus (TC plus CC genotype) is probably a risk factor in the occurrence of Deficiency syndrome in HBC patients. Copyright © 2012 Qing-Ya Li et al.

Recent studies based on epidemiological models published in this journal and elsewhere have demonstrated encouraging patterns suggesting that herbal treatment may improve prognosis in advanced colon and lung cancer patients. Various problems exist with data from nonrandomized studies of this type, but a strong signal of potential positive effect can be seen. The therapeutic mechanisms of traditional Chinese medicine in metastatic cancer are discussed against a hypothetical, dualistic antiproliferation model and immune-stimulation model of tumor progression and regression. Recommendations are made for a strategy to demonstrate more conclusively the efficacy of adjunct herbal treatment during cancer chemotherapy and for discussions with patients until such time as the efficacy trials are completed. © SAGE Publications 2011.

In this study, two invasive mammary carcinoma cells (MDA-MB-231 and 4T1) were utilized to evaluate the inhibitory activities of platycodin D, osthole, and the two in combination. The anti-proliferative effect was tested using the MTT and BrdU assay, and the combination of 15. μM osthole and 75. μM platycodin D was used for subsequent analyses. The anti-invasive effect was evaluated by the transwell assay. The results showed that the combination treatment reduced both cell proliferation and invasion. Western blot and real-time PCR revealed that the platycodin D-osthole combination significantly decreased TβRII, Smad2, Smad3 and Smad4 gene or protein expressions, as well as effectively blocked TGF-β-induced phosphorylation of Smad2 and Smad3. Thus, this study demonstrates that the anti-cancer effects of the platycodin D-osthole combination in breast cancer cells involve proliferation inhibition and invasion blockade, both of which may be mediated by perturbations in the TGF-β/Smads pathway. © 2013 Elsevier B.V.
