Background technology
Blood fat is the general name of contained lipid in human plasma, including cholesterol, triglyceride, cholesterol ester, beta lipoprotein, phospholipid, not esterified fat acid etc..When serum cholesterol exceedes normal value 230 milligrams/100 milliliters, triglyceride more than 140 milligrams/100 milliliters, beta lipoprotein more than 390 milligrams/more than 100 milliliters time, hyperlipidemia can be referred to as.
The cause of disease of hyperlipidemia:
(1) Primary hyperlipemia, it is simply that originally without any other disease, hyperlipemia occurs, is usually because of inherited genetic factors.
(2) Secondary Hyperlipidemia, it is simply that due to the hyperlipemia that a variety of causes causes, such as diabetes, hypothyroidism, nephrotic syndrome, renal transplantation, biliary obstruction etc..
(3) Bad Eating Habit hyperlipemia together, as eating and drinking too much at one meal, be addicted to drink, monophagia, diet are irregular.
(4) certain drug induced hyperlipemia of long-term taking, such as contraceptive, hormone medicine etc..
(5) hyperlipemia that Nervous and Mental Factors causes, it is simply that due to long-term psychentonia, cause endocrine and metabolic disorders, forms hyperlipemia year in and year out.
The mode of prevention hyperlipemia:
(1) reasonable diet: reduce the absorption level of metabolism of lipid and cholesterol, controls body weight, it is prevented that or correct obesity, diuresis row's sodium, regulate blood volume, protect the heart, brain, Renal vascular systemic-function.Adopt low fat low cholesterol, low sodium, homovitamin, appropriate protein and energy diets.
(2) select suitable sports events: according to own situation, select rational sports events.
(3) exercise intensity is grasped: exercise heart rate is the 60~70% of my maximum heart rate, is approximately equivalent to the maximal oxygen uptake of 50~60%.Within general 40 years old, Rate control is at 140 beats/min;50 years old 130 beats/min;Within more than 60 years old, it is advisable within 120 beats/min.
(4) suitable motion frequency: middle-aged and elderly people, particularly old people reduce due to organism metabolism level, the time lengthening recovered after fatigue, therefore motion frequency can optionally increase and decrease, and is generally advisable for 3~4 times weekly.
(5) suitable movement time: movement time controls at 30~40 minutes every time, afternoon, motion was best, and should adhere to motion exercise all the year round.

Experiment one: the experimentation of Chrysosplenium nudicaule seed extract effect for reducing blood fat
1 experiment material
1.1 medicine Chrysosplenium nudicaule seed extracts (prepared by the method described in description embodiment 1 of the present invention);XUEZHIKANG JIAONANG (Beijing WBL Peking University Biotech Co., Ltd).
1.2 reagent triglyceride determination test kits, T-CHOL measures test kit, low-density LP determination reagent box, high-density LP determination reagent box.
1.3 animal Kunming mouses, male and female half and half, body weight 18~22g.
1.4 instrument B-260 type thermostat water baths, TDL80-2B type low speed centrifuge, DG5033A type enzyme-linked immunosorbent assay instrument.
2 experimental techniques
The preparation of 2.1 test samples
2.1.1 the medicinal liquid of high dose group is prepared precision and is weighed Chrysosplenium nudicaule seed extract sample 3g, and adding 100mL concentration is 0.5%CMC-Na, is configured to the medicinal liquid that concentration is 0.03g/mL, standby.
2.1.2 the medicinal liquid of low dose group is prepared precision and is weighed Chrysosplenium nudicaule seed extract sample 1.5g, ibid method, is configured to the medicinal liquid that concentration is 0.015g/mL, standby.
2.1.3 the medicinal liquid of positive controls is prepared precision and is weighed Xuezhikang content 5g, ibid method, is configured to the medicinal liquid that concentration is 0.05g/mL, standby.
Egg yolk liquid 75mL is drawn in the preparation of 2.2 egg-nog solution, puts in the graduated cylinder of 100mL, with normal saline dilution to 100mL, is made into the egg-nog homogeneous solution of 75%.
2.3 packets take 50 Kunming mouses with administration, male and female half and half, body weight is within the scope of 18~22g, it is randomly divided into 5 groups, often group 10, it is respectively as follows: Normal group, hyperlipidemia model group, positive controls, high dose Chrysosplenium nudicaule seed extract administration group and low dosage Chrysosplenium nudicaule seed extract administration group, gastric infusion.It is 0.5%CMC-Na solution that Normal group and hyperlipidemia model group give concentration every day, and giving volume is 0.2mL/10g;Positive controls, Chrysosplenium nudicaule seed extract high dose administration group, Chrysosplenium nudicaule seed extract low dosage administration group gives relative medicine respectively, and dosage is 1g/kg, 0.6g/kg and 0.3g/kg respectively.Being administered 14 days, last two hours after administration, except Normal group, all the other respectively organize equal lumbar injection 75% egg-nog solution 0.02mL/g modeling, after modeling 20 hours, take blood from eyeball, by blood sample in 3000rpm min-1Centrifugal 10min, separation obtains serum, operates according to T-CHOL, triglyceride, low density lipoprotein, LDL and high density lipoprotein test kit description, measures the concentration of T-CHOL (TC), triglyceride (TG), low density lipoprotein, LDL (LDL-C) and high density lipoprotein (HDL-C).
2.4 statistical procedures the data obtained SPSS10.0 statistical softwares carry out statistical analysis, analyze result with± s represents, statistically significant with P < 0.05.
3 experimental results
After various dose Chrysosplenium nudicaule seed extract is administered 14 days, measuring the concentration of the T-CHOL (TC) in each group of experiment mice serum, triglyceride (TG), low density lipoprotein, LDL (LDL-C) and high density lipoprotein (HDL-C) respectively, experiment and analysis result are in Table 1.
Table 1 various dose Chrysosplenium nudicaule seed extract administration group on the impact of the corresponding blood lipids index of mice (± s)
Note: compare with Normal group, ##P < 0.01;Compare with hyperlipidemia model group, * * P < 0.01, * P < 0.05
Experimental result shows, the water average specific Normal group of TC, TG, LDL-C of hyperlipidemia model group significantly raises (P < 0.01), and the level of HDL-C decreases than Normal group (P < 0.01), it was shown that induced Hyperlipidemia in Mice model modeling success;Compared with model group, Chrysosplenium nudicaule seed extract high and low dose administration group all can significantly reduce TC, TG, LDL-C level (P < 0.01) of mice, can raise the level (P < 0.05) of HDL-C, and effect of high dosage becomes apparent from.
4 conclusions
This experimentation shows that the reduction of TC, TG, LDL-C is had obvious effect by Chrysosplenium nudicaule seed extract, HDL-C is had obvious rising effect, Chrysosplenium nudicaule seed extract has the definite effect reducing laboratory animal blood fat, and it has the exploitation prospect for blood lipid-lowering medicine.
Research is it is also shown that the Chrysosplenium nudicaule seed extract of the present invention also has good hypotensive effect, it is possible to treatment vascular hypertension.
