RESUMO

To explore the positioning of acupoints, a research was done with PubMed for system reviews and clinical trials on treatment of low-back pain with sham-acupuncture controlled design from January 1, 2010 to October 27, 2017. Six system reviews and 12 sham-controlled acupuncture random trials were found. The statistical difference was not found in all the 6 trials with standard acupoint compared with the sham-acupuncture among the 8 penetrating skin sham-control trials. The statistical difference was found in the two trials with penetrating skin sham control, who was used individualized treatment, twirling for arrival or palpation for point. It is considered that sham-acupuncture penetrating skin is not a placebo, and needling with standard or dynamic acupoint may reduce low-back pain, and dynamic acupoint positioning may be better than standard acupoint positioning.

RESUMO

<p><b>OBJECTIVE</b>To observe the expression of hepatocyte nuclear factor 4alpha (HNF4alpha) and the activity of key enzyme glucokinase (GK) in glucose metabolism, and further to investigate the possible mechanism of berberine in treating type 2 diabetes.</p><p><b>METHOD</b>Mouse primary hepatocytes were isolated by an improved single two-step perfusion method. The murine hepatocytes were cultured and incubated with berberine (0, 1, 3, 10, 30, 100 micromol x L(-1)) and 1 mmol x L(-1) metformin for 24 h respectively. The mRNA expression of HNF4alpha were quantified by RT-PCR and the protein expression of HNF4alpha were quantified by Western-blot. And the activity of GK were detected with enzyme kinetics method.</p><p><b>RESULT</b>As compared with the negative control group, at a certain concentration range, the expression of HNF4alpha mRNA and protein and the activity of GK were promoted by berberine. Both of them reached the top at the concentration of 30 micromol x L(-1) (P<0.01). But the metformin made no difference with the negative control group on the expression of HNF4alpha and the activity of GK.</p><p><b>CONCLUSION</b>It is suggested that the effects of berberine on improving glucose metabolism can be mechanically associated with its up-regulating the HNF4a expression and inducing the activity of hepatic glucokinase.</p>

RESUMO

<p><b>OBJECTIVE</b>To investigate the effects of Huanglian Jiedu (HLJD) decoction on vascular endothelial function in type 2 diabetic rats and explore the prophylactic and therapeutic significance and pharmacological mechanism of HLJD decoction in type 2 diabetic angiopathic complication.</p><p><b>METHOD</b>The murine type 2 diabetes models were induced by the intravenous injection of a small dose of streptozotocin plus high fat and high caloric laboratory chow. Then modeled diabetic animals were divided into model group, HLJD group, and aspirin group. Normal ratsfed with routine chow were designated as normal group. The oral glucose tolerance test (OGTT) were performed in all animals, 9 weeks after treatment, the changes of murine body weights and levels of fasting blood glucose (FBG), serum total cholesterol (TC), triglycerides (TG), high density lipoprotein-cholesterol(HDL-C), fasting serum insulin (FINS), serum nitric oxide, plasma endothelin, angiotensin II and von Willebrand Factor (vWF) were determined 10 weeks after treatment.</p><p><b>RESULT</b>Compared with model group, the result of OGTT of HLJD group was improved. The levels of the body weights, TC, TG and ET in HLJD group weredecreased (P < 0.05). The levels of FBG,INS, AngII and vWFwere significantly decreased (P < 0.01), and the levels of HDL-C and NO were obviously increased (P < 0.05), as compared with those in model group. Furthermore. The levels of FBG was lower in HLJD group than in aspirin group (P < 0.05), and the improvement of TG, HDL-C,NO, AngII, vWF levels in HLJD group was more greatly than that in aspirin group, but there was not significant difference between two groups (P > 0.05).</p><p><b>CONCLUSION</b>It is suggested by the present results that HLJD decoction could protect vascular endothelium from early damage in type 2 diabetes. The protective effects of HLJD on endothelium might be related to its ability of reducing the blood glucose, adjusting plasma lipids profiles, improving insulin resistance, antagonizing inflammatory mediators and inducing endothelium-dependent vascular relaxation.</p>
