Objective To investigate the effect of total glucosides of paeong (TGP) on the liver lipid infiltration and fibrosis in rats with non-alcoholic fatty liver disease (NAFLD) induced by fructose and high-fat diet. Methods Fructose-high-fatty induced NAFLD rat model was established. Metformin ( MET,200 mg · kg-1 ) and TGP (200,100 mg · kg-1 ) was intragastrically given to the rats in the treatment group,TGP high dose and low dose group,respectively. Normal control group and model control group was intragastrically treated with equivalent distilled water (10 mL·kg-1 ). At the fourth week after the treatment,all the rats were sacrificed and the indices such as serum fasting blood glucose(FBG),INS,insulin sensitivity index (ISI),triglycerides(TG),apelin-36,visfatin,alanine aminotransferase(ALT),aspartate aminotransferase(AST),free fatty acid (FFA),collagen Ⅲ(COLⅢ),collagen Ⅳ(COLⅣ) were determined. Hepatic content of TG was determined and the pathological changes in the liver tissues were observed under the microscope. Results As compared with the model control group,TGP effectively decreased FBG,INS,TG in serum and liver tissues,activity of ALT and AST in serum and content of FAA,Apelin, Visfatin,COLⅢ and COLⅣ,with significant differences (P<0. 05 or P<0. 01). TGP alleviated lipid infiltration and fibrosis in rat liver tissues. Conclusion TGP can inhibit effectively lipid infiltration and fibrosis of NAFLD rats,probably through improving glucolipid metabolism and antogonizing insulin resistance.

The levels of serum C3 and MDA and the activity of SOD were measured according to the method from corresponding reagent kit. ⑥ To observe the suppressive effect of Xiaohuoluo pills on agar granulation tissue hyperplasia in mice:Fifty-nine NIH mice were selected and given subcutaneous injection of 20 g/L agar of 0.5 mL for each. 24 hours later, the mice were assigned into 3 groups by a lot: diclofenac group (diclofenac, 10 mg/kg,I.g..), Xiaohuoluo pills group (Xiaohuoluo pills suspension, 5.54 g/kg, I.g.) and model group (distilled water, the same volume as other groups, I.g.), once a day within 7 successive days; On the 8th day, the mice were sacrificed. The hyperplasiainhibiting effect was presented in the form of the mass of agar granulation tissue in one kilogram body mass ⑦ To observe the suppressive effect of Xiaohuoluo pills on acetic distortion reaction: Sixty-three NIH mice were se lected and assigned into 3 groups by a lot: diclofenac group (diclofenac,50 mg/kg, I.g.), Xiaohuoluo pills group (Xiaohuoluo pills suspension, 5.54 g/kg,I.g.) and model group (distilled water, the same volume of other groups, I.g.),once a day within 2 successive days. At 2 hours after the last administration, the mice were given intraperitoneal injection of 0.1 mol/L acetic acid of 0.2 mL for each one. The times of distortion of mice within 20 minutes were counted. ⑧ To observe the effect of Xiaohuoluo pills on the acute exudative inflammation evoked by dimethylbenzene, croton oil and carrageenan, and the level of prostaglandin E in the inflammatory exudates:Totally 219 NIH mice were selected and assigned into 3 groups by a lot:diclofenac group (diclofenac, 50 mg/kg, I.g.), Xiaohuoluo pills group (Xiaohuoluo pills suspension, 5.54 g/kg, I.g.) and model group (distilled water, the same volume of other groups, I.g.) once a day within 2 successive days. At 2 hours after the last administration, dimethylbenzene of 25 μL was spread on the right ear for 20 minutes, or croton oil of 25 μL was also spread on the right ear, 4 hours later, the swelling of right ear was calculated (mass of right ear-mass of left ear). 10 g/L carrageenan of 20 μL was subcutaneously injected into the right foot, 3 hours later, the swelling degree was calculated (The difference of right foot and left foot); and the level of prostaglandin E in the inflammatory exudates was measured. ⑨ t test(t' test for heteroscedasticity) was used for comparing the difference in measurement data among groups.MAIN OUTCOME MEASURES: Pharmacological effect of Xiaohuoluo pills on secondary immune response, specific immunity, non-specific immunity and free radical injury as well as pain and many other inflammations in mice.RESULTS: Totally 628 NIH and ICR mice were involved in result analysis. ① The level of IgG and CIC of mice in the model group was significantly higher than that in the other 3 groups respectively (P ＜ 0.01),while the level of C3 was significantly lower than that in the other 3 groups (P ＜ 0.05 to 0.01). ② The swelling degree of mice in the diclofenac group and Xiaohuoluo pills group was significantly lower than that in the blank control group respectively ( both P ＜ 0.01). ③ The rosette rate of RBC-C3b receptor and RBC immune compound in the blank control group was significantly higher than that in the other 2 gro ups respectively (P ＜ 0.01). ④ The phagocytic index (K value )in the diclofenac group and Xiaohuoluo pills group was significantly lower than that in the blank control group, respectively (both P ＜ 0.01).⑤ IgM-type HC50 and the level of serum MDA of CY group and Xiaohuoluo pills group were obviously lower than those in the immune control group (P ＜ 0.01),while the level of C3 was higher than that of immune control group, there was no significant difference in the activity of serum SOD between CY group or Xiaohuoluo pills group and immune control group (P ＞ 0.05). ⑥The ratio of agar granulation tissue mass to body mass in the diclofenac group or Xiaohuoluo pills group was significantly lower than that in the model group(P ＜ 0.01).⑦ The times of distortion of mice within 20 minutes in the diclofenac group or Xiaohuoluo pills group were signifi cantly less than those of model group(P ＜ 0.01,0.05).⑧The ear swelling degree of dimethylbenzene-induced inflammatory models and croton oil-induced inflammatory models,and foot swelling degree of carrageenan-induced acute inflammatory models as well as the level of prostaglandin E in the inflammatory exudates in the diclofenac group were significantly milder or lower than those in the model group(P ＜ 0.05 to 0.01),and the level of prostaglandin E in the inflammatory exudates in the Xiaohuoluo pills group was significantly lower than that in the model group (P ＜ 0.01).CONCLUSION: Xiaohuoluo pills possess pharmacological effects of immunosuppression, anti-proliferative inflammation, analgesia and antioxidation.

Objective To investigate the effect of physician guidance on cigarette cessation in current smokers with chronic obstructive pulmonary disease(COPD).Methods Cigarette cessation education and routine telephone follow-up was provided for 70 COPD patients.Pulmonary function and exhaled carbon monoxide level were detected every 3 months.Results After 6 months' follow-up,28 participants(40.00%) successfully quitted cigarette smoking.Seventeen subjects (24.28%) experienced relapse,with mean cessation time(3.08±0.33) months.Once receiving physician guidance,5 re-attempted to quit cigarette smoking,and 12 reduced tobacco consumption. Sixteen subjects(22.86%) did not quit smoking,although the mean cigarette consumption per day was decreased by 60%.Nine participants (12.86%) showed no change in smoking habit. Conclusion Physician guidance could impreve the rate of cigarette cessation in COPD patients.Intensive intervention may be correlated with successful smoking cessation.

Objective To investigate the pathologic morphology and immunohistochemical phenotypes of sarcomatoid carcinoma(SC) of the fallopian tube.Methods One case of SC of the fallopian tube was studied under the light microscopy for morphology.Immunohistochemistry was used to detect the expression of CK,EMA,S-100,Desmin,SMA,Leu-7,CD68,actin,and Vimentin in SC tissues.Pathologic features and biological behaviors of SC were analyzed in combination with the review of literature.Results Microscopically carcinomatous and sarcomatous elements co-existed.Usually the sarcomatous element formed the bulk of the lesion.In the sarcomatous tissues,there was no distinguishable bone,cartilage,rhadomyosarcoma,etc. Immunohistochemically the strong expression of CK7,EMA and Vimentin,and the partial expression of S-100,SMA,Leu7,CD68 and actin were detected.Conclusion SC of the fallopian tube is lack of specific symptoms,and its preoperative diagnosis is difficult.B-ultrasonography,CT and MRI are helpful to the staging of SC.Final diagnosis of SC depends on pathological examination and immunohistochemistry.SC is rare,and undergoes blood metastasis in early stage.Prognosis of SC is worst.Early detection of SC is the key to improve the prognosis.

BACKGROUND: Some experiments indicated that applying rosiglitazone on diabetic animals lacking of insulin could not increase insulin and lower blood glucose obviously, which showed that rosiglitazone did not stimulate the excretion of rosiglitazone. The action of rosiglitazone in improving insulin resistance and the effects on the functions of liver and kidneys need more investigations.OBJECTIVE: To investigate whether rosiglitazone can improve the insulin resistance of rats with hyperlipemia, and analyze the possible mechanism.SETTINGS: Guangzhou Hospital of Traditional Chinese Medicine; Guangzhou Institute of Traditional Chinese Medicine and Materia MedicaDESIGN: A stratified randomized controlled animal trial.MATERIALS: Sixty-four Sprague-Dawley (SD) rats (Batch No. 2002A024), SPF grade, half male and half female,weighing 150 to 180 g, aged 6 to 8 weeks were purchased from Guangdong Medical Experimental Animal Center.Normal feed (total quantity of heat 6.9 kJ/g) was enriched with 23% protein, 53% carbohydrate and 5% fat. High fat emulsion (total quantity of heat 15.5 kJ/g) was enriched with 200 g/L lard, 200 g/L cholesterol, 10 g/L bile salt ox,200 g/L propylene glycol, 200 g/L tween-80. High fat and sugar feed (total quantity of heat 21.0 kJ/g) was enriched with 15% protein, 51% carbohydrate and 30% fat after adding 100 g/L glucose, 200 g/L lard and 100 g/L yolk powder then mixing and baking. Rosiglitazone was from GlaxoSmithKline Co Ltd. (Tianjin) (5 mg/tab, Batch No.02110012). Gliclazide was from Servier International and Tianjin Hua Jin Pharmaceutical Factory (100 mg/tab, Batch No.00232).METHODS: The experiment was carried out in Guangzhou University of Traditional Chinese Medicine from April to July in 2003. ① Sixty-four Sprague-Dawley rats, 16 of which were randomly sampled as the normal control group and had been fed with normal feed for 6 weeks. The others were modeled after medical literatures, each one was administered with high fat emulsion (10 mL/kg) by gavage once a day for 14 days. Rats whose FBG≥6.1 mmol/L or 2hBG≥7.8 mmol/L were selected, randomized into 3 groups according to body mass and blood glucose, i.e., negative control (model)group, rosiglitazone group and gliclazide group, there were 16 rats in each group. Except the normal control group, rats in the rosiglitazone group and gliclazide group were gavaged with rosiglitazone for 5 mg/kg and gliclazide for 100 mg/kg respectively, and those in the model group were gavaged with distilled water. All of the rats were fed with high-fat feed once a day for 28 days. From the 21st day, high fat emulsion was added once a day for 7 days. After fasting for 18 hours from the last administration, all the rats were recorded for FBG and administered dextrose 2.78 mol/10 mL .kg or dextrose and drug mixture 10 mL/kg by body mass. Two hours'later, 2hBG was recorded. ② Blood samples were collected from orbital plexus and serum was prepared for detecting the biochemical indexes and immunological indexes in serum, i.e., fasting serum glucose(FSG), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), alanine aminotransferase (ALT), aspartate aminotransferase (AST),blood urea nitrogen (BUN), creatinine (Cr), tumor necrosis factor alpha (TNF-α) and fasting insulin (FINS). The insulin sensitivity index (ISI) was calculated: ISI=ln [1/ (FINS content×FBG content)]. After the rats were killed, their liver suspension was prepared for measuring the levels of TG, superoxide dismutase (SOD), glutathione (GSH) and malondialdehyde (MDA).MAIN OUTCOME MEASURES: ① FBG and 2hBG; ② FSG, blood lipids, TNF-α, FINS and ISI in serum; ③ TG, GSH, SOD and MDA in liver cells; ④ ALT, AST, BUN and Cr in serum. RESULTS: ① Results of FBG and 2hBG: The FBG and 2hBG in the rosiglitazone group [(3.2±0.3), (6.3±1.2) mmol/L]were lower than those in the modelcontrol group [(3.8±0.5), (8.1±2.1) mmol/L, P ＜ 0.01]. The FBG in the gliclazide group [(3.3±0.7) mmol/L] was lower than that in the model control group. ② Results of FSG, blood lipids, TNF-α, FINS and ISI: The FSG, TNF-α and FINS in the rosiglitazone group were (4.2±1.2) mmol/L, (246±45) μg/L and (133±45) pmol/L respectively, which were lower than those in the model control group [(6.6±1.5) mmol/L, (294±65) μg/L, (264±76) pmol/L,P ＜ 0.05-0.01], whereas ISI was higher than that in the model control group (-6.33±0.46, -7.46±0.95, P ＜ 0.01). The FSG and TNF-α in the gliclazide group [(4.1±1.1) mmol/L, (251±62) μg/L] were lower than those in the model control group (P ＜ 0.05-0.01). ③ Results of TG content, GSH deposit, SOD activity and MDA content in liver cells: The TG and MDA contents in liver cells in the rosiglitazone group [(1.00±0.38), (40±17) mmol/g] were lower than those in the model control group [(2.40±0.60), (171±63) mmol/g, P＜ 0.01], the GSH deposit and SOD activity [(51±14) mg/g, (583.45±50.01 ) nkat/g] were higher than those in the model control group [(2.40±0.60) mg/g, (450.09±66. 68) nkat/g, P ＜ 0.05-0.01].The TG and MDA contents in the gliclazide group [(1.20±0.38), (100±30) mmol/g] were lower than those in the model control group, whereas the GSH deposit [(46±15) mg/g] was higher than that in the model control group. ④ Results of ALT, AST, BUN and Cr in serum: The serum contents of BUN and Cr in the rosiglitazone group [(14.3±3.8) mmol/L,(33±9) μmol/L] were lower than those in the model control group [(19.2±5.6) mmol/L, (45±13) μmol/L, P ＜ 0.05].CONCLUSION: Both rosiglitazone and gliclazide can improve the insulin resistance induced by high fat feed.Rosiglitazone is superior to gliclazide in decreasing the high insulin level, decreaseing serum levels of BUN and Cr,improving reduced GSH deposit and enhancing SOD activity.

OBJECTIVE: We used the SD rat's bone marrow stromal cells (BMSCs) cultured in vitro to observe the effects of Bugu Mixture on the apoptosis and to explore the molecular biologic mechanism of the treatment of osteoporosis with Bugu Mixture. METHODS: BMSCs were separated from the bones of the extremities of SD rats in vitro. The morphologic changes, the apoptosis cell cycles, the mitochondrion membrane potential changes, and the Bcl-2 and Bax gene expression were observed, and the effects of Bugu Mixture on the course of cell apoptosis were evaluated. RESULTS: The earlier use of Bugu Mixture could decrease the cells blocked in G0/G1 phase, and promote their synthesis of DNA in S phase. The expression of Bcl-2 was higher in the Bugu Mixture group than that in the all-trans retinoic acid (ATRA) induced group, and the expression of Bax was lower in the Bugu Mixture group than that in the ATRA induced group. The mitochondrion membrane potential descended significantly in the Bugu Mixture group than that in the ATRA induced group. CONCLUSION: The mechanism of the treatment of osteoporosis with Bugu Mixture is that the earlier use of Bugu Mixture can decrease the amount of apoptostic cells induced by ATRA, thus promoting the cell mitosis and restraining the apoptosis. It can also act as a protector to Bcl-2 located on the mitochondrion membrane. By preventing the transferring of the Bax protein from cell-plasma to mitochondrion membrane, it takes the advantage of Bcl-2 in forming Bcl-2/Bax homodimer so as to prevent the opening of the permeability transition pore to avoid the changing of mitochondrion membrane potential and the destruction of biosynthesis caused by the mitochondrion release of apoptosis inducing factors and to reach the objective of restraining apoptosis.

BACKGROUND: Silibinin has broad pharmaceutical effects, such as anti-free radicals, anti-lipid peroxidation, anti-lipoid oxidase, anti-glutathione (GSH) depletion, anti-neoplastic and serum lipid-lowering effects. Clinically, silibinin is often used in treating alcoholic liver disease. OBJECTIVE: To investigate the pharmacological mechanism of silibinin for alcoholic fatty liver in rats. DESIGN: Randomized and controlled study.SETTING: Guangzhou Hospital of Traditional Chinese Medicine.MATERIALS: The experiment was conducted at the Animal Experimental Laboratory of Guangdong Pharmaceutical Institute from August to October 2003. Totally 57 SD rats, without unusual bacteria, weighting (150±10)g and of either gender, were selected. Yiganling tablets containing 38.5 mg silibinin were produced by Zhuzhou No.3 Pharmaceutical Factory (Batch No. 20020808).METHODS: Among the 57 SD rats, 18 rats were regarded as normal control group. Rats in normal control group were administered with normal saline by gavage, and fed with normal food and distilled water in place of alcohol for 10 weeks. Rats in model group and silibinin group were fed with high-calorie food and 100 mL/L alcohol for 6 weeks to establish model of rat alcoholic fatty liver. The other rats were divided into model control group (n=18) and silibinin group (n=21). Rats in model control group were treated with distilled water while those in silibinin group were treated with 100 mg/kg silibinin. Meanwhile, 100 mL/L ethanol and hyperalimentation feed were given for 4 weeks. After animals were killed, TG, SOD, GSH and MDA levels were measured with liver suspension.MAIN OUTCOME MEASURES: Contents of serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AKP), total cholesterol (TC), triacylglycerol (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), tumor necrosis factor (TNF)-α , and transforming growth factor (TGF)-β1.RESULTS: All the 57 rats entered the final analysis. Silibinin could inhibit the activities of serum AST, ALT and AKP [(2 550.5±400.1), (533.4±100.0), (2 217.1±750.2)nkat/L], and the differences were significant as compared with those in model control group [(3 600.7±666.8), (800.2±100.0), (2 900.6±1 333.6) nkat/L, P ＜ 0.05-0.01]. Contents of TG, LDL-C, TNF-α and TGF-β1 in silibinin group [(1.8±0.8), (0.17±0.04), (6.66±1.38), (24.1±4.1) mmol/L] were lower than those in model group [(2.8±1.4), (0.20±0.05), (7.81±1.06), (28.8±6.3) mmol/L] with significant differences (P ＜ 0.05-0.01). Silibinin could increase the content of HDL-C but decrease the contents of TG and MDA (P ＜ 0.05-0.01), and improve SOD activity as well as hepatocyte and fatty degeneration (P ＜ 0.01).However, it had no obvious effect on the content of reduced estathion (P ＞ 0.05).CONCLUSION: Silibinin can inhibitthe formation of alcoholic fatty liver in rats. The pharmacological mechanism of silibinin may involve anti-oxidation, removing free radicals, inhibiting lipid peroxidation, regulating blood lipid component, reducing fatty sediment in liver, and anti-immunoinflammation and anti-hyperplasia effects.
