Objective To investigate the plasma PAF-AH level in type 1 diabetes patients and the association between the PAF-AH gene polymorphism and type 1 diabetes mellitus. Methods Plasma PAF-AH in115 type 1 diabetes patients and 106 controls were determined by PAF-AH assay kit, and PAF-AH gene G275A genotypes were detected by PCR-RLFP. Results The activity of plasma PAF-AH in the patients with type 1 diabetes was significantly lower than that in the controls. Compared with control group, the frequencies of the GA genotype on G275A polymorphism were significantly higher than that in T1DM group. Conclusion The activity of plasma PAF-AH in the patients with type 1 diabetes was significantly lower than that in normal controls. The G275A polymorphism of PAF-AH gene might be related to type 1 diabetes mellitus.

Objective To explore the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of hepatorenal syndrome (HRS).Methods From January 2009 to December 2012,the clinical data of three type 1 HRS cases and five type 2 HRS cases received TIPS operation were collected.The volume of 24 h urine,liver and renal function,and the occurrence of complications of portal hypertension were recorded and followed-up.Wilcoxon rank sum test was performed for non-normal distributed measurement data.Results TIPS of all the patients was successful and combined with devascularization in four patients.Before operation,the serum creatinine and volume of urine was 204.0 (180.8,229.8) μmol/L and 810 (600,925) mL,seven days after operation was 160.7 (120.2,184.0) μmol/L and 1 300 (975,1 500) mL,respectively,and the differences were statistically significant (Z=-2.1 and-2.2,both P＜0.05).One month after operation,renal function of five patients recovered to normal.At the 7th day after operation,total bilirubin level of three patients increased and that of two patients decreased to the preoperative base line value at one month and three month.Mild or moderate hepatic encephalopathy occurred in three patients after operation and relieved after medicine treatment.At 6th month after operation,two of three type 1 HRS patients survived.Of five type 2 HRS patients,one received liver transplantation at 6th week after operation,three of the left four cases survived at the 6th month after operation.Conclusion After safety and efficacy were evaluated,TIPS may be one of the methods used for the treatment of HRS.

The range of effective dose and mechanism of abirritation about water extraction components of Evodiae Fructus on the stomach cold syndrome model in mice were preliminary studied. The method of stomach cold-syndrome model in mice was built, which were administrated with different doses water extraction components of Evodiae Fructus, observing abirritation and toxicity by the classical hot plate method, detecting the level of ALT, AST, PGE2, NO, NOS, MDA, SOD, GSH, GSH-Px, BUN, CR in serum and ALT, AST in hepatic tissue, and recording toxicity symptoms in mice according to the list of relevant toxicity reaction. The water extraction component of Evodiae Fructus has obvious analgesic action after administration 30 min, arriving peak effect after administration 60 min, showing certain "dose-time-toxicity" relationship. ALT and AST levels in mice serum and liver tissue enhanced; PGE2, MDA, NO, NOS enhanced in mice serum; SOD, GSH, GSH-Px reduced; the BUN, CR levels was no significant alteration; liver weight/ body weight enhanced; kidney weight/body weight was no significant alteration. The a irritation mechanism of volatile oil of Evodiae Fructus was connected with suppressing pain transmitters release, per oxidative damage mechanism and NO damage, which also induced hepatotoxicity and the mechanism of hepatotoxicity is main lyoxidative damage, showing certain "dose-time-toxicity" relationship in accordance to hepato-toxicity injury.

OBJECTIVETo preliminarily study the effective dosage range and mechanism of the abirritation of volatile oil of Evodia Fructus on the stomach cold syndrome model in mice, and discuss the correlation between its accompanying toxicity and oxidative damage mechanism, in order to provide the experimental basis for explaining the efficacy-syndrome-toxicity correlation.

METHODThe stomach cold-syndrome model in mice was induced by the classic hot plate test by orally administrating with different doses of volatile oil of Evodia Fructus, in order to observe its abirritation and companying toxic and side effects and detect serum ALT, AST, PGE2, NO, NOS, MDA, SOD, GSH, GSH-Px, BUN, CR and hepatic ALT, AST. The companying toxic symptoms in mice were recorded in toxic reaction integral table.

RESULTVolatile oil of Evodia Fructus had an obvious analgesic effect at 30 min after the oral administration and reached the peak effect at 60 min, with certain "dose-effect" and "time-effect" relations, rises in serum and hepatic ALT and AST levels, serum PGE2, MDA, NO and NOS and hepatic indexes, decreases in SOD, GSH and GSH-Px and no notable change in BUN, CR levels and kidney weight/body ratio. Conclusion: The abirritation mechanism of volatile oil of Evodia Fructus was related to the inhibition of pain transmitter release, peroxidative damage and NO damage, which is accompanied by certain hepatotoxicity, mainly mainly oxidative damage, with a concurrent "dose-time-toxicity" relationship.

In order to safeguard the legitimate rights and interests of the subjects and the interests of the whole society , a relaxed and harmonious environment was created to ensure the normal medical research , clini-cal research trials which fit in trial of ethical review. The protocol assessment form and ICF assessment form to review are two cornerstones of protecting subjects. A good ICF assessment form is a necessary means to help improve the quality of the Ethics Committee for review .

Biomedical research involving human subjects must be approved by the ethical review. The method of improving ethics committee members of the examination quality is not only by the members themselves , but also a good plan of the work table, which is also a necessary means to improve the quality of the ethical review.

OBJECTIVE: To explore the relationship of the expression of thymic stromal lymphopoietin (TSLP) in nasal polyps tissues and the Th2 inflammatory response. METHOD: Sixty patients with nasal polyps were collect ed. The immunohistochemical staining method was used to detect the expression of TSLP in nasal polyps tissues and ELISA method to the expression of IL-4, IL-5, IFN-gamma, IL-13 and analyzed the correlation between them. RESULT: The expression of TSLP in nasal polyp tissues was higher than that in normal inferior turbinate mucosa (P < 0.05). The expression level of IL-4, IL-5, IFN-gamma and IL-13 in nasal polyps tissues were significantly higher than those in control group (P < 0.05). TSLP staining was a statistically significant positive correlation with IL-4, IL5 and IL-13 (r = 0.475, 0.594 and 0.582, respectively, P < 0.01), while inverse correlation with IFN-gamma (r = -0.614, P < 0.01). CONCLUSION The high expression of TSLP might promote T cell differentiation towards Th2, and participated in the occurrence/development of nasal polyps, aggravated the nose Th2 inflammatory response.
