ABSTRACT
OBJECTIVE： To study improvement effects of ethanol extract from Taxillus sutchuenensis on blood glucose level， liver and renal complications in type 2 diabetes mellitus （T2DM） model mice and its mechanism. METHODS： T2DM model was established by high-glucose and high-fat feed combined with intraperitoneal injection of streptozotocin. Totally 60 T2DM model mice were randomly divided into model control group （normal saline）， positive control group [metformin， 150 mg/（kg·d）] and T. sutchuenensis ethanol extract high-dose， medium-dose and low-dose groups [30， 15， 7.5 g/（kg·d）， by crude drug]， with 12 mice in each group. Other 12 normal mice were included in blank control group （normal saline）. After given drug solution or normal saline for consecutive 28 d， the serum levels of FBG， FINS， IL-2， IL-4， IL-12， IFN-γ， Scr， BUN， ALT and AST were detected； 24 h urine was collected to detect the Ucr levels. The insulin sensitivity index （ISI） and insulin resistance index （HOMA-IR） were calculated. HE staining was used to observe the pathological change of hepatocytes. The levels of Bcl-2 and Bax in liver tissue as well as the levels of TLR4 and NF-κB p65 in renal tissue were detected. RESULTS： Compared with blank control group， the serum levels of FBG， FINS， IL-4， ALT， AST， BUN， Scr and HOMA-IR value were increased significantly in model control group， while the levels of Ucr， IL-2， IL-12， IFN-γ and ISI value were decreased significantly （P＜0.01）. The hepatocytes showed obvious pathological changes. Bcl-2 level and Bcl-2/Bax of liver tissue were decreased significantly， while Bax level was increased significantly （P＜0.01）. The levels of TLR4 and NF-κB p65 in renal tissue were increased significantly （P＜0.01）. Compared with model control group， histopathological changes of liver were relieved significantly in T. sutchuenensis ethanol extract groups. Except that there was no significant difference in serum level of IFN-γ and level of NF-κB p65 in renal tissue in T. sutchuenensis ethanol extract low-dose group， other indexes were improved significantly （P＜0.01 or P＜0.05）. CONCLUSIONS： T. sutchuenensis ethanol extract can improve high blood glucose， liver and renal complications， and protect liver and renal function in T2DM model mice. The mechanism may be associated with improving immunofunction， up-regulating anti-apoptosis factors， down-regulating the expression of apoptosis-promoting and inflammation- promoting factors so as to maintain the functional status of hepatocytes and reduce the degree of renal cell damage.
ABSTRACT
Objective To establish the quality control method for Antenoron filiforme. Methods Antenoron filiforme was identified by TLC,and the content of gallic acid was determined by HPLC. The chromatographic conditions were as follows:Aichrom Reliasil C18 column (4. 6 mm×250 mm,5 μm) was used with mobile phase consisted of acetonitrle-0. 1% phosphoric acid(4∶96),the flow rate was 1. 0 mL·min-1 ,and the detection wavelength was 270 nm. Results TLC identification for An-tenoron filiforme was highly specific. Gallic acid content had a good linearity in the range of 0. 08-0. 56μg (r=1. 000 0). The av-erage recovery was 101. 12% and RSD was 2. 20% (n=6). Conclusion The method is simple, feasible,and reproducible, and can be used for the quality control of Antenoron filiforme.
ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinical effect of hemoperfusion combined with hemodialysis in the treatment of severe organophosphate pesticide poisoning.</p><p><b>METHODS</b>Ninety-eight patients with severe organophosphate pesticide poisoning who were admitted to the emergency department of our hospital from March 2005 to September 2013 were equally divided into control group and observation group according to treatment methods. The control group was given conventional emergency treatment, while the observation group was given hemoperfusion combined with hemodialysis and the conventional emergency treatment. The clinical outcomes and complications of two groups were compared.</p><p><b>RESULTS</b>In the control group, 35 patients were cured and 14 patients died, so the cure rate was 71.4%. In the treatment group, 46 patients were cured and 3 patients died, so the cure rate was 93.9%. The treatment group had a significantly higher cure rate than the control group (χ² = 8.611, P < 0.05). And the treatment group had significantly shorter duration of coma (P < 0.01), mean length of hospital stay (P < 0.01), and time to recovery of cholinesterase activity (P < 0.01) and a significantly reduced dose of atropine than the control group (P < 0.01). The control group had significantly more cases of urinary retention than the treatment group (18 vs. 6, χ² = 4.991, P < 0.05). And the control group had more cases of intermediate syndrome, respiratory failure, delayed neurological damage, and rebound than the treatment group.</p><p><b>CONCLUSION</b>Hemoperfusion combined hemodialysis has a good clinical effect and causes fewer complications in treating severe organophosphate pesticide poisoning, so it is worthy of clinical promotion.</p>
