Objective:To study the effect of trigonelline on the change of indicators of serum transaminase, lipoprotein and liver lipid of model rats with non-alcoholic fatty liver diseases and on the expression level of Bcl-2 and Bax proteins.Methods:A total of 45 SD rats were randomly divided into Fthe control group, model group and trigonelline intervention group. Rats in the control group were fed with the common diet, while rats in the model group and intervention group were fed with the high fat diet. 8 weeks later, the intervention group received the intragastric administration of trigonellin e (with the dosage of 40 mg/kg/d) for 8 weeks; while control group and model group received the intragastric administration of saline with the equal dosage. Blood was taken from the abdominal aorta of rats 8 weeks later, detecting the level of a series of indicators of ALT, AST, TG, TC, HDL-C and LDL-C in the serum. After the rats were sacrificed, detect the indicators of TG, TC, SOD and MDA in the liver tissue of rats, as well as the expression of Bcl-2 and Bax in the liver tissue.Results: Results of histopathologic examination showed that the damage degree of liver for rats in the trigonellineintervention group was smaller than the one in the model group, with significantly reduced hepatic steatosis and the partially visible hepatic lobule. The levels of ALT, AST, TC and LDL-C in the serum of rats in the trigonelline group were significantly reduced, while the change in the levels of TG and HDL-C was not significantly different. The levels of TG, TC and MDA in the liver tissues were significantly decreased, while the level of SOD significantly increased; the expression of Bcl-2 protein in the liver tissues of rats in the trigonelline intervention group was significantly increased, while the expression of Bax protein significantly decreased.Conclusions: The trigonelline contributes to the therapeutic effect of non-alcoholic fatty liver diseases. It can also increase the expression of Bcl-2 protein and decrease the expression of Bax protein in the liver tissues, which can protect the liver.

Objective To investigate the association between nonalcoholic fatty liver disease (NAFLD) and metabolism or carotid intima-media thickness (CIMT) in Type 2 diabetic(T2DM). Methods According to the liver B-ultrasonography, a total of 321 T2DM patients were divided into two groups, with or without NAFLD. Metabolic indexes such as BMI, BP, blood glucose, blood lipid, uric acid ( UA ), insulin, C-peptipe,insulin resistance index(HOMA-IR) between the two groups were compared, and the relationships between alanine aminotransferase (ALT) and the above indexes were analyzed. Furthermore,the CIMT of the two groups were compared, and the relationships between NAFLD, ALT and CIMT were investigated by correlation and regression analysis. Results Compared with the group without NAFLD, the patients with NAFLD had higher level of BMI, triglyceride ( TG ), UA, fasting blood glucose ( FBG ), fasting insulin ( FIns ), fasting C peptide (FCP) ,HOMA-IR,and lower level of high density lipoprotein ( HDL-C ) significantly; BMI ( OR = 1.25, P <0. 001 ), TG ( OR = 1.74, P = 0. 008 ) and HOMA-IR ( OR = 2. 33, P = 0.010) were independent risk factors of NAFLD while H DL-C was independent protective factor; ALT was positively correlated with BMI (r = 0. 255, P <0. 001 ) ,TG(r =0. 156,P <0. 018) ,UA(r =0. 239,P <0. 001 ) ,FIns(r =0. 213,P =0. 001) ,FCP(r =0. 199,P <0. 003), HOMA-IR ( r = 0. 247, P < 0. 001 ) and negatively correlated with HDL-C ( r = - 0. 199, P =0. 002) ,and BMI (β =0. 456,P =0. 048) ,UA (β =0. 021 ,P =0. 025) and HOMA-IR(β =3.634 ,P =0. 004)were independent associated facrors. The difference of CIMT between the two groups didn't reach statistical significance, while mutiple regression analysis revealed that ALT was independently associated with CIMT(β =0. 002,P = 0. 013). Conclusion T2DM patients with NAFLD show more serious disorder of metabolism and insulin resistance. ALT is an independent risk factor of CIMT in T2DM patients.

Objective To assess the efficacy and safety of esomeprazole in long-term or intermittent treatment of gastroesophageal reflux disease (GERD). Methods Twenty-eight patients with GERD who accepted esomeprazole 20 mg bid for 2 weeks were further divided into long-term treatment group and intermittent treatment group according to the protocol of therapy. Patients in long-term treatment group were received minimum dose that was needed to relief the symptoms for more than 6 months, whereas those in intermittent treatment group were received esomeprazole 20 mg qd until the symptoms completely disappeared, if symptoms relapsed the patients were treated again.The dosage, recurrence of symptoms and the side effects were compared between two groups. ResultsThirteen patients in long-term treatment group were treated for 7-44 months (20 mg daily in 7,twice daily in 5 and every other day in 1). While 15 patients in intermittent treatment group had a good relief of the symptoms. No adverse reactions was found in two groups. The follow-up study of 10-57 months in intermittent treatment group revcaled that the longer the treatment maintained,the longer the symptoms relieved (r=0. 447, P= 0. 008). Conclusion It is safe for esomeprazole in relieving symptoms of patients with GERD by long time or intermittent use.

The effects of synthetic oil used as dietary fat source on the body weight, organ weight, liver and serum lipids of rats during the hypercho-lesterolemic inducing period were investigated, and comparison was made with lard and soybean oil diets.Weanling albino rats were fed first with stock diet for 3 weeks. Bloods were collected from tails, and serum cholesterol contents were determined. Based upon the body weight and serum cholesterol level, animals were then divided into 5 groups. Four groups were fed respectively with synthetic oil, synthetic oil plus linoleic acid, lard and soybean oil diets, all were supplemented with 1% cholesterol. The, fifth group served as control, was fed with soybean oil diet without cholesterol. Body weights and serum lipids (cholesterol and triglyceride) were measured at intervals during the experiment. Organ weights and liver lipids (total fat, cholesterol and triglyceride) were determined at the end of the experiment.The results showed that there was marked sex difference between male and female rats, that is, synthetic oil diet caused significant lower body weights and lower serum cholesterol levels to female but not to male rats.Cholesterol inducing diets apparently increased the liver weights of all animals, yet fat accumulation only occured in those livers of rats fed with lard and soybean oil diets. The liver fat contents of animals of both synthetic oil and synthetic oil plus linoleic acid groups were at normal level.This experiment reveals that when dietary cholesterol intake is high, the use of synthetic oil as a dietary fat source for maintaining a normal lipid metabolic condition in the body seems beneficial.

AIM To explore the effect of long-term nebulized inhalation of nitroglycerin (Neb-NTG) on high pulmonary blood flow-induced pulmonary artery hypertension (PAH). METHODS 24 male Wistar rats were randomly divided into shunting group, Neb group and control group. An arteries-venous shunt was performed between the abdominal aorta and inferior vena cava shunting was produced in rats of Neb and shunt groups. Twelve weeks after the operation, nebulized nitroglycerin was inhaled by rats in the Neb group using pressurized air ejection mobilization, while nebulized saline was inhaled by rats of the other two groups. Ten minutes inhalation was given each day for each rat. After three weeks of inhalation, pulmonary artery systolic pressure (PASP) and mean pressure (PAMP) of each rat were evaluated by using a right cardiac catheterization procedure. Systemic arterial pressure (SAP) was reorded continuously by catheterization procedure. The ratio of right ventricular mass to body weight (RV/BW) and the ratio of right ventricular mass to left ventricular plus septal mass (RV/LV+S) were detected. Pulmonary vascular microstructure was measured. RESULTS PASP, RV/BW and RV/LV+S were significantly increased in shunt rats as compared with those of normal controls (P0.05). Muscularization of small pulmonary artery was obviously decreased in Neb-group compared with shunt group. CONCLUSION Long-term Neb-NTG ameliorates high pulmonary blood flow-induced PAH and pulmonary vascular remodeling.
