ABSTRACT
Objective To investigate the effects of Pollen Typhae total flavone (PTF) on INS-1 pancreaticβcell damage induced by palmitic acid ( PA) . Methods INS-1 pancreatic β cells were given long-term induction with PA to establish the impaired cell model, and then were intervened with PTF. Cell viability was determined by tetrazolium salt ( XTT) colorimetry. Results PA impaired the viabilities of INS-1 pancreatic β cells in concentration- and time-dependent manner, and PTF improved the impairment of INS-1 pancreatic β cells induced by PA in concentration -dependent manner. Moreover, PTF showed better improvement on the impairment when the INS-1 pancreatic β cells were impaired more seriously by PA. Conclusion PTF has effects on ameliorating the impairment of INS-1 pancreaticβcells induced by PA for long time.
ABSTRACT
Objective To investigate the effects of Pollen Typhae total flavone ( PTF) , an extract from Pollen Typhae which has the actions of activating blood and removing stasis, on inflammatory factors and insulin sensitivity in type 2 diabetic rats. Methods SD rats were used as the experimental animal. Type 2 diabetic rats induced by high fat diet plus low dose of streptozotocin were randomly divided into model group, PTF group (in the dosage of 200 mg·kg-1·d-1) , and rosiglitazone group (in the dosage of 4 mg·kg-1·d-1) . Additionally, normal control group was set up. After treatment for 4 weeks, plasma interleukin 6 ( IL-6) and tumor necrosis factor alpha ( TNF-α) levels were detected, the insulin tolerance test ( ITT) was performed, and the protein expression of suppressor of cytokine signaling-3 ( SOCS-3) in skeletal muscle was determined. Results After treatment for 4 weeks, the plasma levels of IL-6 and TNF-α, the homeostasis model of insulin resistance ( HOMA-IR) , and expression level of SOCS-3 in skeletal muscle in the model groups were significantly increased ( P﹤0.05) as compared with those in the normal control group, and insulin tolerance was also impaired in the model group ( P﹤0.05) . Compared with the model group, IL-6 level and HOMA-IR were markedly decreased in the PTF group ( P﹤0.05) , and the impaired insulin tolerance was obviously improved (P﹤0.05) . The level of SOCS-3 in the skeletal muscle of PTF group was also much lower than that of the model group and rosiglitazone group (P﹤0.05) . Conclusion PTF has effects on decreasing the levels of plasma IL-6 and SOCS-3 in the skeletal muscle and on improving insulin sensitivity in type 2 diabetic rats.
ABSTRACT
This study was aimed to explore the curative effect of Zhuo-Du-Qing (ZDQ) particles on diabetic cystopa-thy (DCP) based on the theory of turbid toxin. A total of 100 DCP patients were randomly divided into the control group with 47 cases and the treatment group with 53 cases. Mecobalamin tablets was given in the control group. And ZDQ particles were given to the treatment group. The treatment course was 3 months. The observation was made on the bladder residual urine (BRU), clinical manifestation integral, hemodynamic indexes, HOMA-IR and HbA1c before and after the treatment. The results showed that compared with pretreatment, the BRU, clinical manifestation integral, hemodynamic indexes, and HOMA-IR were significantly reduced (P < 0.01). Compared with the control group, the BRU, clinical manifestation integral, hemodynamic indexes, and HOMA-IR were also significantly reduced (P <0.01). The effective rate in the treatment group was 81.1%, which was significantly higher than 59.6% in the control group (P< 0.05). There were no obvious changes on the blood routine examination, urine routine examination, stool routine examination, liver function, renal function, electrocardiogram and so on before and after treatment. It was con-cluded that the treatment of DCP with ZDQ particles was safe and effective. To remove toxin and descend turbid may be another effective treatment method for DCP. The occurrence and development of DCP were closely related to the turbid toxin.
ABSTRACT
Patients with hypertension coupled with metabolic syndrome (MetS) are among the high risk population in cardiovascular and cerebrovascular diseases. To reduce the prevalence of cardiovascular and cerebrovascular diseases, it is essential to appropriately control blood pressure together with other cardiovascular risk factors.
ABSTRACT
Microalbuminuria (MAU) is a key component of metabolic syndrome (MetS) and is an early sign of diabetic nephropathy as well. Although routine Western medicine treatments are given to MetS patients to control high blood pressure, hyperglycemia and dyslipidemia, some patients still experience progressive renal lesions and it is necessary to modify and improve the treatment strategy for MetS patients.
