Objective To investigate the effects of simvastatin pretreatment on ischemia-reperfusion (I/R)injury to the spinal cord in rats. Methods Ninety-six healthy male SD rats weighing 220-280 g were randomly divided into 3 groups (n=32 each): Ⅰ group sham operation (group S); Ⅱ group I/R and Ⅲ group simvastatin pretreatment (group Si). The animals were anesthetized with 10% chloral hydrate 0.4 ml/100g. I/R to the spinal cord was induced by cross-clamping the aorta below renal artery for 45 min followed by reperfusion according to Zivin in group Ⅱ and Ⅲ. In group Ⅲ simvastatin 20 mg/kg was administered via gastric tube in the morning for 3 days before operation. Neurological function was assessed and scored (0 = no spontaneous movement of the hindlimbs, 7 = normal gait) at 2, 6, 12 and 24 h (n = 8 at each time point). The animals were then sacrificed and the lumbar segment (L2-5) of the spinal cord was removed for microscopic examination and determination of expression of TLR4 mRNA, NF-κB protein activity and TNF-α and ICAM-1 contents in the spinal cord. Results I/R to the spinal cord significantly increased TLR4 mRNA expression, NF-κB protein activity and TNF-α and ICAM-1 content in the spinal cord and decreased neurological scores in group Ⅱ compared with group C. Simvastatin pretreatment significantly attenuated the I/R-induced increase in the above-mentioned variables and ameliorated I/R-induced neurological dificit and histopathological damage. Conclusion Simvastatin pretreatment has neuroprotective effects on the spinal cord against I/R injury by attenuating inflammatory response.

Objective To optimize the soaking treatment method for increasing the germination of Amomum villosum Lour.(AVL) seeds.Methods Nine groups were set up: the control group(without soaking treatment),treatment group 1(soaking AVL seeds with naphthylacetic acid 15 mg/mL for 8 hours),treatment group 2(soaking with gibberellin 100 mg/L for 30 hours) and treatment groups 3~8(soaking with clean water for 8,20,30,40,45 and 50 hours respectively).The sowing amount was 100 grains in each group for each time,and the seeds were planted in the outdoor pot at a planting space of 4cm?4cm.Results Naphthylacetic acid had an obvious inhibition on the germination of AVL seeds and delayed the shooting.Gibberellin promoted the germination and shooting of the seeds.Soaking with clean water for 8 hours had no obvious effect on the seed germination,but soaking for 20~50 hours increased the seed germination to various degrees,in particular soaking for 30~50 hours.Conclusion Soaking with gibberellin or clean water can increase the germination of AVL seeds.This method is simple and practical and economic,and is worth of extensively applying in the sowing and breeding of AVL seeds.

Objective To compare the lipid lowing effect and the clinical safety between intensive therapy with Chinese medicine Zhihitai and atorvastntin in patients with moderate and high risk of atherosclerosis. Methods All the patients were randomly divided in to a Zhibitai group (n = 85) receiving 480 mg of Zhibitai orally twice a day or an atorvastatin group (n = 84) receiving 10 mg atorvastatin orally once daily. Blood lipoproteins, myocardial enzymes, fiver and renal function were measured before treatment and at the fourth and eighth week after therapy , while high sensitive creactive protein (hs-CRP), P-selectin, matrix-metall proteinase-9 (MMP-9) and soluble intercellular adhering molecule-1 (SICAM-1) were detected before treatment and eighth week after therapy in all patients. Results TC and LDL-C were significantly decreased while HDL-C was increased in both groups after 4 and 8 weeks treatment (P < 0. 05). TG was decreased in Zhibitai group after 4 and 8 weeks of treatment, but it was decreased in atorvastatin group only after 8 weeks of treatment. Inflammatory factors such as hs-CRP, P-selectin, MMP-9, SICAM-1 were decreased significantly (all P < 0. 01), but there was no significant difference between the two groups. There were no difference in liver and kidney function, myocardial enzymes and incidence of muscle-ache and digestive system side reaction. ConclusionsBesides the lipoprotein disorder, inflammatory factors in patients with moderate and high risk of atherosclerosis could be regulated with intensive therapy of Zhibitai. Most importantly, it is safe to use Zhibitai clinically.

Objective:To observe the effect of pioglitazone on carotid artery intima-media thickness (IMT) and plaque-positive rate in patients with metabolic syndrome, and to ifnd a new way to improve arterial remodeling in patients with metabolic syndrome. Methods:Patients with metabolic syndrome were randomly divided into a control group (n=60) and a pioglitazone group (n=61). All subjects received basic therapeutic measures, i.e, appropriate medication to control blood pressure, blood sugar and cholesterol. Pioglitazone (15 mg/d) was given to patients in the pioglitazone group, and placebo (vitamin C) in the control group for 24 weeks. Color doppler ultrasound was used to measure carotid artery IMT and plaque-positive rate of patients in the 2 groups atfer the intervention. Japan’s Hitachi 7600-020 automatic biochemical analyzer was used to measure fasting serumal triglycerides, total cholesterol, high density lipoprotein cholesterol, low-density lipoprotein cholesterol, free fatty acids, fasting blood glucose, 2-hour postprandial glucose and liver and kidney function, etc. The differences between groups after the intervention were analyzed and compared in IMT, plaque-positive rate and all blood biochemical indicators. Results:Atfer the intervention, compared with the control group, carotid artery plaque-positive rate and the levels of triglyceride and free fatty acid decreased in the pioglitazone group (P<0.05), but there was no difference in IMT of carotid artery and other blood biochemical indicators between the 2 groups (P>0.05). Conclusion:Pioglitazone intervention can significantly improve pathologic artery remodeling, and it can more effectively inhibit the arterial plaque-formation than basic therapeutic measures in patients with metabolic syndrome.

[Objective] To observe the effect of biological fertilizers on the yield and quality of Amomum villosum (AV). [Methods] Field experiment method was used to observe the effect of different kinds and different amount of biological fertilizers on AV. Biological fertilizers were: A (mainly composed of fermented chicken manure), B (mainly composed of fermented filter of sugarcane) and C (mixed with fertilizer A and biological fertilizer at certain proportion). The fertilizer amount was 150, 112 and 75 g****m-2 per time. Content of bornyl acetate in AV was detected by gas chromatography. [Results] The three kinds of biological fertilizers increased the yield of AV but had no obvious effect on its quality; high- and moderate-amount fertilizer increased the yield of AV, in particular fertilizer A (112 g?m-2 per time). The three kinds of fertilizers had no effect on the content of bornyl acetate in AV. [Conclusion] Reasonable application of fertilizers is one of the important ways to raise the yield of AV.
