Objective
This study aimed to explore the association of integrin α7 with clinicopathological characteristics and overall survival (OS) in clear cell renal cell carcinoma (ccRCC) patients.
Methods
179 ccRCC patients who underwent nephrectomy were included in this retrospective study. Tumor tissue and paired adjacent tissue specimens of patients were obtained. Immunohistochemistry assay was performed to detect integrin α7 expression. OS was calculated with the median follow‐up duration of 91.0 months (range: 3.0‐116.0 months).
Results
Integrin α7 was highly expressed in tumor tissue compared to paired adjacent tissue (P < .001), and tumor integrin α7 high expression was correlated with higher pathological grade (P = .004), increased T stage (P = .017), and advanced TNM stage (P = .033). Kaplan–Meier curve showed that patients with integrin α7 high expression (mean OS = 69.8, 95%CI: 60.5‐79.1 months) presented with worse OS compared to patients with integrin α7 low expression (mean OS = 101.8, 95%CI: 96.0‐107.7 months; P < .001). Multivariate Cox's regression analysis further disclosed that tumor integrin α7 high expression independently predicted poor OS (P < .001).
Conclusion
Integrin α7 is upregulated and correlates with higher pathological grade, increased T stage, and advanced TNM stage, meanwhile it also acts as a valuable prognostic factor for worse survival in ccRCC patients.
Obesity significantly impacts living a normal life by increasing morbidity. Additionally, obesity has been shown to be closely associated with severe inflammation in adipocytes. It is widely reported that berberine (BBR) has an anti-inflammatory effect and can reduce glucose and lipid accumulation, whereas ginsenoside Rb1 (Rb1) has been shown to have a significant inhibitory effect on insulin resistance and lipid peroxidation. In this study, we aimed to explore the synergetic effect of BBR and Rb1 on tumor necrosis factor alpha (TNF-α)-treated adipocytes and the mechanisms underlying it. We found that TNF-α reduced cell viability, facilitated the production of inflammatory factors, induced adipogenesis, activated the nuclear factor kappa B (NF-κB) pathway, and increased the expression of peroxisome proliferator-activated receptor gamma, CCAAT enhancer-binding protein alpha, and sterol regulatory element-binding protein-1 c in adipocytes. However, these effects were significantly alleviated by BBR or Rb1. Additionally, a synergetic effect was observed when BBR and Rb1 were used in combination. The effects of BBR in combination with Rb1 on cell proliferation, inflammation, adipogenesis, and the NF-κB pathway in TNF-α-treated adipocytes were significantly abolished by receptor activator of nuclear factor kappa-Β ligand, which is an activator of the NF-κB pathway. Collectively, the results revealed that BBR and Rb1 have a synergetic protective effect against TNF-α-induced inflammation in adipocytes. The mechanism underlying this synergetic effect was found to be inhibition of the NF-κB signaling pathway.
Objective
To investigate the efficacy and safety of Tiaoqiheying decoction in treating acute ischemic stroke.
Methods
This prospective randomized study enrolled 102 patients with ischemic stroke who were randomly assigned to the control (placebo), external (external Tiaoqiheying decoction), and external/internal groups (oral and external Tiaoqiheying decoction) groups. Cholesterol (CHO), triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) levels and the National Institute of Health Stroke Scale (NIHSS), modified Ashworth scale (AMS), visual analog scale (VAS), Barthel Index (BI), and Fugl–Meyer score (FMS) were determined before and after treatment.
Results
NIHSS scores were lower in the external/internal group than in the external and placebo groups. MAS and VAS scores for all patients were also lower after 4 weeks than before treatment, and they were significantly lower in the external/internal group versus the control group. CHO, TG, and LDL levels were significantly lower after 2 and 4 weeks, and their levels were lower in the external/internal group than in the other two groups. BI and FMS were higher in the external/internal group than in the other groups after 2 and 4 weeks of treatment.
Conclusion
Tiaoqiheying decoction may improve spasmodic pain and lipid metabolism after stroke.
As an example of Shenyi capsule on non-small-cell lung cancer combined with chemotherapy, this review discusses the synergistic effect and mechanism of natural drugs in oncotherapy from the yin-yang perspective in ancient Chinese philosophy, so as to reflect the therapeutic principle of natural drugs for tumor more comprehensively. The major focuses of this review are on the philosophical thinking of yin-yang as a tool which can not only explain the effect of Shenyi capsule in NSCLC combined with chemotherapy but also explore the mechanism of Shenyi capsule at the cellular and molecular level. Learning from the “yin-yang” thinking of ancient Chinese philosophy will bring more enlightenment to the research and development of traditional Chinese drugs in the future.
