Objective: To explore the effect and possible mechanisms of intermittent alkaline on rat vascular smooth muscle cells (VSMCs) calcification induced by high phosphorus. Methods: VSMCs were isolated from rat thoracic aorta and cultured in vitro. The fourth generation VSMCs were randomly divided into control group, high phosphorus+ pH7.4, high phosphorus+ pH7.5, high phosphorus+ pH7.6 and high phosphorus+ pH7.7 group with random number table. The control group was cultured in DMEM with 10% fetal bovine serum. Other groups were cultured in DMEM with 10 mmol/L β-glycerophosphate and alkalized by 7.4% NaHCO₃ to adjust the pH respectively. After the intervention of 4 hours, the control group was replaced with the normal medium containing 10% fetal bovine serum, the other 4 groups were replaced with high phosphorus based on the pH value of the culture medium, and then replaced the culture medium every other day. After 4 days intervention, the mRNA and protein expression of L type calcium channel β₃ subunit(LTCC β₃) and Runt related transcription factor 2 (Runx2) were detected by RT-PCR and Western blot. After 4 days intervention, the level of VSMC calcium ion was detected by Fluo-3/AM. After 14 days intervention, alkaline phosphatase (ALP) activity was measured by enzyme linked immunosorbent assay (ELISA) and the calcification was observed by measuring calcium content. Results: (1) Compared with control group, the gene and protein expressions of LTCC β₃ were higher in high phosphorus+ pH7.4 group (0.49±0.03 vs. 0.23±0.02 and 0.45±0.03 vs. 0.26±0.02 respectively, all P<0.05). Compared with high phosphorus+ pH7.4 group, the mRNA(0.86±0.05) and protein(0.62±0.04) expressions of LTCC β₃ were higher in high phosphorus+ pH7.5 group (P<0.05). Compared with high phosphorus+ pH7.5 group, the mRNA(0.99±0.05) and protein(0.80±0.03) expressions of LTCC β₃ were higher in high phosphorus+ pH7.5 group (all P<0.05). Compared with high phosphorus+ pH7.6 group, the mRNA(1.16±0.05) and protein(0.93±0.03) expressions of LTCC β₃ were higher in high phosphorus+ pH7.7 group (all P<0.05). (2) Compared with control group, calcium ion influx were higher in high phosphorus+ pH7.4 group (124.61±6.06 vs. 75.68±7.82, P<0.05). Compared with high phosphorus+ pH7.4 group, calcium ion influx was higher in high phosphorus+ pH7.5 group(210.85±9.75, P<0.05). Compared with high phosphorus+ pH7.5 group, calcium ion influx was higher in high phosphorus+ pH7.6 group(298.44±11.42, P<0.05). Compared with high phosphorus+ pH7.6 group, calcium ion influx was higher in high phosphorus+ pH7.7 group(401.13±11.41, P<0.05). (3) Compared with control group, the mRNA and protein expressions of Runx2 and ALP were higher in high phosphorus+ pH7.4 group (0.60±0.04 vs. 0.34±0.03, 0.42±0.04 vs. 0.21±0.02, 67.2±4.3 vs. 23.2±2.3 respectively, all P<0.05). Compared with high phosphorus+ pH7.4 group, the mRNA(0.76±0.05) and protein(0.68±0.03) expressions of Runx2 and ALP(102.1±5.4) were higher in high phosphorus+ pH7.5 group (all P<0.05). Compared with high phosphorus+ pH7.5 group, the mRNA(0.90±0.05) and protein(0.90±0.05) expressions of Runx2 and ALP(139.3±4.9) were higher in high phosphorus+ pH7.6 group (all P<0.05). Compared with high phosphorus+ pH7.6 group, the mRNA(1.11±0.05) and protein(1.08±0.06) expressions of Runx2 and ALP(197.0±6.7) were higher in high phosphorus+ pH7.7 group (all P<0.05). (4) Compared with control group, the calcium content were higher in high phosphorus+ pH7.4 group ((75.4±4.3)mg/g pro vs.(25.2±2.1)mg/g pro, P<0.05). Compared with high phosphorus+ pH7.4 group, the calcium content were higher in high phosphorus+ pH7.5 group ((100.8±5.7) mg/g pro, P<0.05). Compared with high phosphorus+ pH7.5 group, the calcium content were higher in high phosphorus+ pH7.6 group ((143.5±6.1) mg/g pro, P<0.05). Compared with high phosphorus+ pH7.6 group, the calcium content were higher in high phosphorus+ pH7.7 group ((205.1±8.2) mg/g pro, P<0.05). Conclusion Intermittent alkaline stimulation can promote high phosphorus induced rat VSMCs calcification possibly through upregulating LTCC β₃ subunit gene and protein expression, increasing calcium ion influx and enhancing VSMCs phenotypic transformation.

ObjectiveTo evaluate the clinical efficacy and safety of Notoginseng Radix et Rhizoma powder in treating dyslipidemia by regulating the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway. MethodSixty patients with dyslipidemia （syndrome of combined phlegm and stasis） treated in the Third Affiliated Hospital of Henan University of Chinese Medicine from May 2021 to June 2022 were selected in this study and randomized into two groups according to the randomized， double-blind control principle. The control group was treated with Xuezhikang capsules + Notoginseng Radix et Rhizoma powder placebo and the observation group with Notoginseng Radix et Rhizoma powder + Xuezhikang capsules placebo for 6 weeks. The clinical efficacy， traditional Chinese Medicine （TCM） syndrome scores， and liver and kidney function indicators were evaluated at weeks 0， 3， and 6. Enzyme-linked immunosorbent assay （ELISA） was employed to determine the expression of vascular endothelial growth factor （VEGF）， kinase insert domain receptor （KDR）， epidermal growth factor （EGF）， and epidermal growth factor receptor （EGFR） in the peripheral serum. Quantitative Real-time PCR was employed to measure the mRNA levels of KDR， EGFR， PI3K， and Akt in the mononuclear cells of the peripheral blood. ResultThe observation group （83.33%） showed the total effective rate comparable to that of the control group （89.66%） and no adverse reactions. Compared with before treatment， the patients in the observation group showed decreased TCM syndrome score and serum levels total cholesterol （TC）， triglyceride （TG）， and low-density lipoprotein cholesterol （LDL-C） and after being treated for 3 and 6 weeks （P<0.05）， the level of high-density lipoprotein cholesterol （HDL-C） showed an upward trend, but the difference was not statistically significant. After treatment， the two groups showed no significant differences. Compared with that before treatment, the mRNA expression of PI3K, Akt and EGFR in peripheral blood mononuclear cell and the expression of EGF, VEGF and KDR in serum of the observation group showed a downward trend with time, in which the mRNA expression of PI3K, Akt, VEGF and KDR decreased more significantly (P<0.05)，The expression levels of KDR mRNA and serum EGFR show a trend of first increasing and then decreasing.Compared with the control group after treatment, there was no statistically significant difference in mRNA expression of PI3K, Akt, EGFR, and KDR, as well as serum levels of EGF, EGFR, VEGF, and KDR between the two groups of patients at the same time point. ConclusionNotoginseng Radix et Rhizoma powder is safe and effective in correcting dyslipidemia. It may inhibit the PI3K/Akt signaling pathway by down-regulating the expression of VEGF/KDR to lower the blood lipid level.
