Chinese Journal of Primary Medicine and Pharmacy 2011;18(5):590-592
Objective To explore carotid atherosclerosis and its relative factors of maintenance peritoneal dialysis patients. Methods The general clinical conditions,hematobiochemical parameters and color ultrasound parameters of 27 maintenance peritoneal dialysis patients and 24 controll patients were collecled. General clinical conditions included body weight, height and BMI. Hematobiochemical paremeters included Hb, Alb, LP (a), TC, TG, HDL-C,LDL-C, CRP, plasma fibrinogen, C3, Apo-A 1, Apo-B, LP (a). Color ultrasound parameters included plaque incidence rate,thickness of vascularendothelium(IMT). Results Compared with the controll group,maintenance peritoneal dialysis patients: plaque incidence rate, thickness of vascularendothelium (IMT) increased significantly, Age, TC, TG,LDL-C,LP (a), dialysis time increased significantly in plaque-positive group(all p < 0. 05), while Hb, Alb andPAB decreased significantly (all P < 0.0 5) , CRP increased significantly (P < 0.0 1) . Conclusions In maintenance peritoneal dialysis group,CRP,LP(a) had positive relationship with C-IMT. CRP had negative relationship with ALb. CRP had not relationship with age and dialysis time. There were relationships among malnutrition,inflammation and atherosclerosis in maintenance peritoneal dialysis patients. Interdiction of the relationship may played a very important role in ameliorating the prognosis of the maintenance peritoneal patients.
2.Evaluating the Compensation Level of Urban Basic Medical Insurance in Jiangsu
Chinese Health Economics 2013;(12):30-32
Objective: To evaluate the compensation level of the Urban Employee Basic Medical Insurance ( UEBMI ) and Urban Resident Basic Medical Insurance ( URBMI ) in Jiangsu province . Methods: Take catastrophic health expense as the bottom line of compensation ratio for the basic medical insurance, the benefit of hospitalization expenses of those joining the insurance as the actual line of compensation ratio, and quartile division was used to comparatively analyze the differences between the bottom line of compensation ratio and the actual line of compensation ratio. Results: Take 10%as the critical value of catastrophic health expense, the actual line of compensation level is higher than the bottom line of compensation level in UEBMI, and there is reverse in URBMI. Conclusion: In some extent, the compensation level of UEBMI has relieved the economic burden of the poor jointed group because of sickness, while limited compensation level of UEBMI is in need of further improvement.

Academic Journal of Second Military Medical University 1981;0(03):-
Objective:To investigate and compare the influences of Ghrelin and growth hormone releasing peptide 6(GHRP-6) on the contractility of stomach smooth muscle in guinea pigs,and to study the related mechanism.Methods: The myenteric plexuses of gastric fundus and antrium in guinea pigs were stimulated with electrical field stimulation(EFS) to observe the influence of Ghrelin and GHRP-6 on the contractility of stomach smooth muscle.The influences of N-nitro-L-arginine(L-NNA) and L-Arginine(L-AA) on the effect of Ghrelin and GHRP-6 were studied to disclose the mechanism of the effects of Ghrelin and GHRP-6.Results: The circular muscle tissues of the gastric fundus generated on-relaxations and off-contractions when stimulating myenteric plexuses with 1-16 Hz electrical field;the on-responses induced relaxation could be reduced by L-NNA and the off-contractions induced contraction could be blocked by atropine and guanethidine.In fundic strips,ghrelin and GHRP-6 could decrease the on-response induced relaxation and increase off-response induced contraction of the muscle,with the effect of Ghrelin obviously stronger than that of GHRP-6.L-NNA could increase the effects of Ghrelin and GHRP-6-induced muscle contraction,and L-AA could decrease their effects.In the antral strips,electrical field stimulation of myenteric plexuses led to disappearance of relaxation wave,only leaving off-contractions.Both ghrelin and GHRP-6 could increase that contraction.Conclusion: Both ghrelin and GHRP-6 can promote the contractility of stomach smooth muscle in guinea pigs through stimulating myenteric plexuses of gastric fundus and antrium,which might be related to the NO pathway.

5.Progress in building animal model of irritable bowel syndrome
Basic & Clinical Medicine 2006;0(08):-
Irritable Bowel Syndrome(IBS) is a common disease of intestinal disorder.It is characterized by chronic or recurrent abdominal pain or discomfort along with altered bowel function.The underlying mechanisms of IBS remain unclear.Several studies showed that the attack of IBS might be related to the gastrointestinal motility,visceral hypersensitivity,infection of the bowel and several other factors.Existing animal models can be divided into 2 broad categories based on their primary pathogenetic mechanisms: those initiated by a central nervous system-directed(psychosocial) stressor and those stems from a gut-directed stressor(gut inflammation,infection).This article reviews the current research of IBS animal model.
