Objective To explore the changes of the total antioxigenic capacity (T-AOC) of the plasma and red blood cells (RBC) in the acute pulmonary edema rats induced by acute formaldehyde inhalation. Methods SD rats were randomly dived into the formaldehyde group and control group, then were exposed to formaldehyde and physical saline vapor respectively in a chamber for 2 hours, the actions and vital signs were observed. After treatment the rats were taken out the chamber, 5 hours later, the T-AOC of the red blood cells and plasma were measured and the body, lungs and heart were weighted, the lung /heart weight index and lungs/body weight index were calculated, the pathological examination was done. Results Compare with the control group, the lung weight, lung/body weight index, lung /heart weight index and the T-AOC of the plasma increased, the T-AOC of RBC and body weight decreased significantly(P

Objective To study the effects on inhibit tumor growth and enhance immune function of Ganoderma lucidum polysaccharide(GLP)combined with low-dose cisplatin in tumor-bearing mice.Methods 2 × 106 Lewis cells in 0.1 mL PBS were injected subcutaneously into the flanks of healthy female BALB/c nude mice (5~6 weeks old).When the tumor volume reached 100 mm3,mice were randomly assigned to 4 groups,control group (Oral gavage of 0.5 ml PBS and intraperitoneal injection of 0.5 ml),GLP group (gavage once every two days,40 mg/kg GLP in 0.5 ml),cisplatin group (intraperitoneal injection once every two days,2 mg/kg cisplatin in 0.5 ml) and the combination group (such as the above dose of cisplatin and GLP).After the treatment regimen was complete,the mice were sacrificed,and the tumors were removed,photographed,weighed,and prepared for histological analysis.The immune cells in spleen and peripheral blood were analyzed by flow cytometry.Results GLP can effectively increase anti-tumor effect of the small dose cisplatin,improve the survival of tumor-bearing mice,promote Th cells convert to Th1 in peripheral blood,increased the expression of CD 11c + on DC cell surface (GLP group 4.59% VS the control group 1.06%,the combined group 7.21% VS the cisplatin group 2.8%).Conclusion GLP can improve the immune function of tumor-bearing mice,had synergistic anti-tumor growth with low dose cisplatin,moreover,reduce renal toxic effects of cisplatin.

Objective To study the effects of the Yinlingtong capsules on intracellular triglyceride,fatty acid oxidation levels and CPT-1/ACC-β in HHL-5 cells.Methods After treated HHL-5 cells with different doses Yinlingtong capsules,intracellular triglyceride content and the fatty acid oxidation level were detected by the kits.The CPT-1β and ACC-β mRNA levels were detected by Q-PCR.Results Yinlingtong capsules could reduce triglyceride content (compared with the control group,triglyceride content of0.5,1 and 2 mg/ml dose group were reduced by 9.5%,14.3% and 19.4%,respectively),enhance the level of fatty acid oxidation by a dose-response relationship(compared with the control group,the level of fatty acid oxidation of 0.5,1and 2 mg/ml dose group were increased 4.3%,6.9% and 11.2%,respectively),but could not affect the CPT-1βand ACC-β mRNA levels.Conclusion Yinlingtong capsules reduced the accumulation of fat in HHL-5 hepatocytes,and the specific impact mechanism needs to be further explored.

Objective To study the effects of Ganoderma lucidum polysaccharide (GLP) on PBMCs and the related immune mechanism.Methods PBMCs from cancer patients and healthy donors were isolated and treated with different doses of Ganoderma lucidum polysaccharides (10 ng/ml,50 ng/ml and 100 ng/ml).DC cell costimulatory molecules (HLA-DR,CD83,and CD11 c),Th1 (CD3 + CD8-IFN-γ+) cells,Th2 (CD3 + CD8-IL-4+) cells and NK (CD3-CD56+) were analyzed by FCM.Furthermore,The CD3+ CD4+ Th ceils were separated by immunomagnetic beads and stimulated with Ganoderma lucidum polysaccharides at different concentrations in culture.After 24 h,the cytokine expression levels of Th1 and Th2were detected by RT-PCR.The expressions of Th1 differentiation-related transcription factor,STAT4,were analyzed by Western blot.Results Ganoderma lucidum polysaccharides can significantly stimulate in vitro Thl cell differentiation (P<0.01) in a dose depend manner.It correlates with an increased expression of STAT4 and the elevated mRNA expression levels of Th1 cytokineincluding IL-12,IFN-γ and TNF-α (P<0.01).Conclusion Ganoderma lucidum polysaccharides may promote Th1 differentiation and increase the secretion of Th1 cvtokines through the upregulation of STAT4.

AIM: To study the therapeutic effect of Angeng Recipe(AGR) on the female climacteric rats. METHODS: Female SD rats were collected and randomly divided into climacterium,AGR(low dose,medium dose and high dose),nilestriol and young control groups.The level of hormone in serum and hypothalamus was analyzed after using AGR,the alteration of organ coefficient of uterus,adrenal,appendix cerebri and thymus were detected,the apoptosis of ovary granulosa cells was detected by fluorescence microscope and flow cytometer. RESULTS: E_2 contents in high dose group were higher than those in the climacterical group.FSH contents in high dose group were lower than those in the climacterical group.Uterus and adrenal gland viscera coefficient of high dose group,medium dose and low dose group were higher than that of climacterical group,The apoptosis of cells in medium dose group showed lower than that in the climacterical group. CONCLUSION: AGR could adjust the function of endocrine secretion by the effect on ovaries and appendices suprasphenoidalis directly or indirectly,and the mechanism of action was multitarget and the regulation was entirety.AGR could relieve the degeneration of sexual gland axis,and improve symptomatic in climacteric.

Objective To observe the effect of dihydromyricetin of ampelopsis grossedentata on lipid metabolism and antioxidation in atherosclerosis (AS) rats. Methods Sixty Wistar rats were randomly divided into five groups (n = 12 each):normal control group, model control group, positive control group, high dose dihydromyricetin group (40 mg·kg-1 ) and low dose dihydromyricetin group (10 mg·kg-1 ). Except normal control group, rats in the other groups were injected with a single dose of vitamin D3(600 000 U·kg-1 ) and loaded with high fat diet to establish AS model. Simvastatin (5 mg·kg-1 ) was intragastrically administered to positive control group. High and low dose dihydromyricetin groups received intragastric administration of 40 and 10 mg·kg-1 dihydromyricetin, respectively. Equal volume of purified water was given to normal and model group. After 24 weeks of administration, serum levels of lipids, activities of superoxide-dismutase (SOD) and malonicdialdehyde (MAD) were determined. Results As compared with model control group, triglycerides (TG) of high and low dose dihydromyricetin groups was decreased [(191. 65±101. 10) vs. (111. 10±29. 29) and (120. 55±38. 12) mg·L-1 , respectively], total cholesterol (TC) was decreased [(151. 64±33. 62) vs. (148. 49±30. 14) and (118. 90±27. 38) mg·L-1 ], and high density lipoprotein cholesterol (HDL-C) was increased [(1. 29±0. 68) vs. (2. 10±0. 70) and (1. 62±0. 61) mmol·L-1 ], low density lipoprotein cholesterol (LDL-C) was decreased [(5. 01±1. 33) vs. (3. 97±0. 78) and (4. 28±0. 79) mmol·L-1 ], activity of SOD was increased [(141. 03±42. 52) vs. (187. 97±42. 08) and (150. 99±46. 17) U·mL-1 ], and MDA was decreased [(20. 51±3. 81) vs. (17. 64±1. 54) and (18. 52± 3. 42) nmol·mL-1 ], with significant differences (P<0. 05, P<0. 01). Conclusion Dihydromyricetin can reduce the level of serum lipid, improve antioxidation activity, and has therapeutic effect for atherosclerosis.
