[0129] 2.11 Summary:

[0130] 1) There was no statistical difference (P>0.05) in the body weight of the animals in each group.

[0131] 2) Comparing with the negative control group, the serum TC, TG and LDL-C values in the modeling control group at baseline after modeling and at weeks 2, 4 and 9 of treatment were increased (P<0.05 or 0.01). The hybrid hyperlipemia rat model was established.

[0132] 3) Compared with the modeling control group, at each time point, the positive control group demonstrated certain effects on reducing the serum total cholesterol in the rats, which, however, were not significant, indicating that the reference drug atorvastatin has no significant effect on reducing the blood lipids in the hybrid hyperlipidemia rat model and is not an ideal therapy.

[0133] 4) The traditional Chinese medicine composition disclosed herein started to demonstrate an effect of reducing TG at week 2 of treatment, especially in the 833 mg/kg group, and the effects of reducing TG at weeks 4, 7 and 9 of treatment was statistically significant (P<0.05). Meanwhile, the 833 mg/kg group also showed a preliminary effect of reducing TC, and particularly, the effect of reducing TC was statistically different (P<0.05) at week 9 of treatment. The effect on reducing TG in the 417 mg/kg group at weeks 4, 7 and 9 of treatment was at the critical point for statistical difference in the statistical tests (P value between 0.05 and 0.10).

[0134] 5) Compared with the negative control group, the weight and coefficient of the liver in the modeling control group were increased (P<0.01); compared with the modeling control group, the weight and coefficient of the organ/tissue in the test compound groups had no statistically significant different (P>0.05). The organs were preserved for future delivery to the sponsor.

[0135] 6) Conclusion: under the experimental conditions, the animal studies showed that the traditional Chinese medicine composition disclosed herein has significant effects on reducing blood lipids and reducing cholesterol, and particularly has a significant effect on reducing blood triglyceride. Meanwhile, the effect on reducing blood lipids has certain association with the dose.

[0166] 3.8 Methodology

[0167] 3.8.1 High-fat and high-cholesterol modeling feed: A maintenance feed containing 20.0% of sucrose, 5% of lard, 1.0% of cholesterol, 0.1% of sodium cholate, appropriate amounts of casein, calcium bicarbonate, powdered stone and the like. Other than crude fat, in the modeling feed, moisture, crude protein, crude fat, crude fiber, crude ash, calcium, phosphorus and calcium:phosphorus all satisfied the national standard for maintenance feed. The feed was provided by Guangdong Medical Laboratory Animal Center.

[0168] 3.8.2 Preparation of the test compound solution: A proper amount of the test compound was ground and dissolved in a small amount of purified water. The mixture was transferred to a volumetric flask, brought to the volume with purified water and stirred for complete dissolution to obtain an 83.35 mg/mL solution for the test compound group 2. The solution was 2-fold diluted to about 41.65 mg mL for the test compound group 1.

[0169] 3.8.3 Preparation of the reference drug solution: 1 rosuvastatin calcium tablet (strength: 10 mg/tablet) was ground and dissolved in a 0.5% CMC-Na solution. The mixture was transferred into a volumetric flask and brought to 30 mL with the 0.5% CMC-Na solution to obtain a concentration of about 0.33 mg/mL. The solution was shaken to mix well before use.

[0170] 3.8.4 Modeling: The negative control group was given the maintenance feed and the remaining groups were given the 21% high-fat feed until the end of the study.

[0171] 3.8.5 Administration: Mice in the positive control group, the test compound 833 mg/kg group and the test compound 1667 mg/kg group were intragastrically administered with the corresponding drug solution at 20 mL/kg body weight daily, and mice in the negative control group and the modeling control group were administered with purified water of the same volume once daily for 60 days.

[0172] 3.8.6 Measurements:

[0173] 1) General state: The general clinical states of the mice were observed and recorded once daily.

[0174] 2) Body weight: The body weight was measured once at the start and end of the study and once weekly during the study. The weight gain on D30 of treatment (D29 of treatment—D1 of treatment) and D60 of treatment (D60 of treatment—D1 of treatment) was calculated.

[0175] 3) TC, TG, LDL-C and HDL-C levels: After the modeling period was finished, the animals were anesthetized by isoflurane inhalation without fasting. The blood was collected from orbital venous plexus, and centrifuged at 3000 r/min at a low temperature for 10 min. The serum was separated to determine the total cholesterol TC, triglyceride TG, high-density lipoprotein HDL-C and low-density lipoprotein LDL-C levels, and the remaining serum samples were stored in a freezer at −80° C.

[0176] 4) Weight of organs: the weights of the liver, the left kidney, the left perirenal fat, the right kidney and the right perirenal fat were measured, and the coefficient of organ were calculated according to the following formula. The liver and the right kidney were weighed and stored at −80° C.

[00001]$\mathrm{Coefficient}\mathrm{of}\mathrm{organ}=\frac{\mathrm{Weight}\mathrm{of}\mathrm{organs}\left(g\right)}{\mathrm{Animal}\mathrm{body}\mathrm{weight}\mathrm{on}D60\mathrm{of}\mathrm{treatment}\mathrm{period}\left(g\right)}$

[0177] 5) Pathological test: after the end of study, the mice were fixed in a supine position, the thoracic cavities of the mice were quickly opened, normal saline was perfused throughout the whole body from the left ventricle, and then 4% paraformaldehyde was perfused for fixation. The whole artery from the heart to the lower iliac artery branch was removed, preserved in 4% paraformaldehyde fixing solution, treated and stained with Oil Red O. The aortic arch, along with the heart and common carotid artery (right) was quickly isolated and fixed with 4% paraformaldehyde. The common carotid artery was stained with Oil Red O, and the aortic arch was stained with HE and Sirius.

[0178] 3.9 Statistics: The data are represented by (x±s). The statistical analysis was carried out using SPSS 21.0 software; The pairwise comparison was conducted by one-way analysis of variance with a test level α=0.05.

[0179] 3.10 Results

[0180] 3.10.1 General clinical observation: during the study, animal #2 in the negative control group died on d30 of treatment. Anatomy showed enlarged that left kidney, with the upper half part of the left kidney being milky white and the lower half part being dark red. The left kidney was longitudinally dissected, showing a large cavity containing a milky fluid and a clear fluid. The right kidney was shriveled and atrophied, and aggregated blood clots were found. Milky white fat-like fluid was seen in the bladder, which accumulated at the bladder outlet, accounting for about half of the intralight volume of the bladder. No visible abnormality in the gross anatomy of the rest organs of the abdominal cavity was observed, no visible abnormality in the gross anatomy of the thoracic cavity was observed, and no plaque in the thoracic aorta was observed. Judgment: In vivo cholesterol accumulation and hyperlipidemia are normal manifestations in ApoE knockout mice, and the cause of death of the mice was inferred to be individual differences, abnormal fat metabolism and excessive cholesterol accumulation. No abnormality was observed in body shape, hair, skin, feces, muscle tension, gait, spirit, respiration and the like of the animals.

[0186] 3.10.3.2 Weight and coefficient of organs on d60 of treatment (Tables 13 and 14): Compared with the negative control group (♂), the weights and the coefficients of the liver and the left perirenal fat in the modeling control group (♂) were increased (p<0.05 or 0.01), the coefficients of the left kidney and the right kidney were decreased (p<0.05 or 0.01), and the weights of the left kidney and the right kidney and the coefficient of the left kidney in the modeling control group (♀) were decreased (p<0.05 or 0.01); compared with the modeling control group (♂), the weight of the left kidney in the positive control group (♂) and the test compound 833 mg/kg group (♂) was decreased (p<0.05); compared with the modeling control group (♀), the weight of the right kidney in the test compound 833 mg/kg group (♀) was decreased (p<0.05).

[0187] 3.10.4 Pathological examination results: The full-length aortic Oil Red O staining showed that red plaque-like substances were found in the aortic bifurcation part of ApoE.sup.−/− mice fed with high-fat feed, and the atherosclerotic plaque of the modeling group was significantly increased as compared to that in the negative control group (FIG. 1). Meanwhile, compared with the modeling control group, the aortic Oil Red O staining of the test compound 833 mg/kg and 1677 mg/kg groups showed that the formation of atherosclerotic plaque was obviously reduced after 60 days of treatment (FIG. 2). The HE-stained aortic arch sections showed that certain histological changes were seen in the modeling control group as compared to the negative control group, and were mainly manifested by accumulation of foam cells under the intima in the aortic arch and formation of intimal plaque (FIG. 3). The positive control group showed no significant difference as compared to the modeling control group. However, in the test compound 833 mg/kg and 1667 mg/kg groups, only foam cell aggregation was observed under the intima in the aortic arch, and no intimal plaque was formed (FIG. 3). The Sirius-stained aortic arch sections showed that the modeling control group had significant collagen fiber hyperplasia at the plaque part in the intima and the adventitia as compared to the negative control group. In the test compound groups, particularly the 1667 mg/kg group, only milder collagen fiber hyperplasia of the adventitia was found, and no collagen fiber hyperplasia was observed in the intima (FIG. 4). As shown in FIG. 5, the carotid artery Oil Red O staining showed that intraluminal red lipid droplets were formed, and the test compound 833 mg/kg and 1667 mg/kg groups were significantly superior to the modeling control group and the statin intervention group. In the test compound 1667 mg/kg group, only a trace amount of red lipid droplets were observed in the carotid lumen (FIG. 5).

[0188] 3.11 Summary

[0189] The traditional Chinese medicine composition disclosed herein has significant effects on reducing the formation of atherosclerotic plaques and reducing the weight gain in model animals.

Example 4. Clinical Trials for Treatment of Hyperlipidemia

[0190] The subjects were from Zhejiang Huzhou Ruibo Traditional Chinese Medicine Clinic (No. 322, Meizhou Road, Huzhou City, Zhejiang Province) and Beijing Tongyitang Clinic (1st Floor, Building 4, Zhongguancun Life Science Park, Changping District, Beijing).

[0191] Data of treatment using the powder A, B or C for dry ointment extract of the present invention in these subjects from the two clinics as described above were collected, where 14 subjects had increased total cholesterol (>6.2 mmol/L) and triglyceride (>1.7 mmol/L), 11 subjects had increased total cholesterol, and 88 subjects had increased triglyceride (Table 15).

[0192] The patients received one to three 14-day courses of treatment. The patients were administered twice daily, receiving 1 or 2 bags of granule formulation each time according to disease conditions, each bag of granule formulation containing 1250 mg of the powder A, B or C for dry ointment extract.

[0193] With 10% reduction in total cholesterol or triglyceride levels as the efficacy endpoint, in the 14 subjects with increased total cholesterol and triglyceride, nearly 79% of the patients had effective reduction in total cholesterol, 93% of the patients had effective reduction in triglyceride, and 10 patients had both effective reductions (Table 15 and FIG. 6).

[0194] The traditional Chinese medicine composition disclosed herein has an effective rate of 45% in reducing increased total cholesterol (shown in Table 15 and FIG. 7) and an effective rate of close to 90% in reducing hypertriglyceridemia (shown in Table 15 and FIG. 8). The traditional Chinese medicine composition disclosed herein has excellent efficacy on patients with severe hyperlipidemia, particularly in subjects with severe blood triglyceride (triglyceride>5.6 mmol/L).
