1H NMR metabonomics approach was used to reveal the chemical difference of urine between patients with Xiao-Chaihu Tang syndrome (XCHTS) and healthy participants (HP). The partial least square method was used to establish a model to distinguish the patients with Xiao-Chaihu-Tang syndrome from the healthy controls. Thirty-four endogenous metabolites were identified in the 1H NMR spectrum, and orthogonal partial least squares discriminant analysis showed the urine of patients with Xiao-Chaihu Tang syndrome and healthy participants could be separated clearly. It is indicated that the metabolic profiling of patients with Xiao-Chaihu Tang syndrome was changed obviously. Fifteen metabolites were found by S-pot of OPLS-DA and VIP value. The contents of leucine, formic acid, glycine, hippuric acid and uracil increased in the urine of patients, while threonine, 2-hydroxyisobutyrate, acetamide, 2-oxoglutarate, citric acid, dimethylamine, malonic acid, betaine, trimethylamine oxide, phenylacetyl glycine, and uridine decreased. These metabolites involve the intestinal microbial balance, energy metabolism and amino acid metabolism pathways, which is related with the major symptom of Xiao-Chaihu Tang syndrome. The patients with Xiao-Chaihu Tang syndrome could be identified and predicted correctly using the established partial least squares model. This study could be served as the basis for the accurate diagnostic and reasonable administration of Xiao-Chaihu-Tang syndrome.

Objective To present a preliminary latest procedure for portal hypertension and evaluate the technical feasibility and efficacy of portacaval shunt creation through the percutaneous transhepatic approach in order to make a hemodynamic comparison with that of the classic TIPS.Methods Thirty-eight patients with portal hypertension(36 men;mean age 57 years,range 32～73)were referred for PTPS procedure because of bleeding varices(n=36),intractable ascites(n=1),and hepatopulmonary syndrome(n=1).The severity of liver disease was classified as Child-Pugh B in 27 and C in 11.The PTPS was created by a percutaneous transhepatic puncture into right portal vein and then through left portal vein to the hepatic segment of IVC followed by a prefabrication stress stent-graft placement at the very site.Results Technical and functional success of 100% was achieved in all patients,without related complications.The postprocedural portal vein-IVC gradients mean 13 cmH_2O was achieved with the follow-up period mean 493 days.No recurrence of variceal bleeding and controlled refractory ascites were achieved,and still more with primary patency rate of the involved vascular structure up to 94.8% at 365 days,much better than classic TIPS. Conclusions Portacaval shunt creation using the prefabrication stress stent via percutaneous transhepatic technique is safe and feasible.The compact coincidence was obtained between the stent and the involved vessel with restoration of intrahepatic portal venous bemodynamics together with partial lowering of portal venous pressure and guaranteeing intrahepatic perfusion through right portal vein.It is also obviously to have postoperative prevention of shunt restenoses and lowering postoperative incidence of hepato-encephalopathy.

OBJECTIVETo explore the relationship between genetic polymorphisms of glutathione S-transferase (GST) M1, T1 and susceptibility to mountain sickness.

METHODSForty-three soldiers with acute mountain sickness and 80 healthy soldiers matching with sex/age and training under the same condition were divided into case group and control group. A multiple polymerase chain reaction method was used to detect GSTM1 and GSTT1 genes in genomic DNA isolated from peripheral blood cells from both cases and controls.

RESULTSThe frequency of the GSTT1 positive genotype was significantly higher in cases (69.8%) than in controls (42.5%) (P = 0.004, OR = 3.12, 95% CI 1.42 approximately 6.86). The frequency of GSTM1 negative genotype was also higher in cases (72.1%) than in controls (52.5%) (P = 0.03, OR = 2.34, 95% CI 1.05 approximately 5.02). Persons with both GSTM1 and GSTT1 negative genotypes had 5-fold more risk than those with GSTT1 negative and GSTM1 positive genotypes in developing mountain sickness (OR = 5.04, 95% CI: 1.00 approximately 25.3).

CONCLUSIONGenetic polymorphisms of glutathione S-transferase M1, T1 may be the risk factors in the development of mountain sickness.

BACKGROUNDThe gradually increasing changes in a human hyperlipidemic diet along with chronic stress might play an important role in the increased numbers of fatty liver. This study investigated the effects of Ilex asprella root decoction on related genes of lipid metabolism in chronic stress in hyperlipidemic fatty liver in rats.

METHODSForty-eight male Wistar rats were randomly divided into four groups: normal control group, model control group, simvastatin group, and Ilex asprella root group. To establish chronic stress and hyperlipidemic fatty liver models in rats, the levels of serum lipids, glucose, liver index, insulin (INS), insulin resistant (IR) index, adiponectin, superoxide dismutase (SOD), glutathione peroxidase (GSH-pX), glutathione (GSH), liver X receptor (LXR), and sterol responsive element binding protein (SREBP)-1c in rats were measured.

RESULTSWhen compared to the normal control group, the levels of serum lipids, glucose, liver index, INS, IR index, and GSH in the model control group significantly increased (P < 0.01). The protein levels of LXRα and SREBP-1c increased (P < 0.05), and the serum adiponectin and the SOD and GSH-pX decreased significantly (P < 0.01). When compared to the model control group, the levels of serum lipids, glucose, liver index, INS, IR index, SOD, and GSH-pX in the simvastatin group and Ilex asprella root group increased in varying degrees (P < 0.01 or 0.05); the serum adiponectin and GSH decreased (P < 0.05), while the protein levels of LXRα and SREBP-1c decreased in varying degrees (P < 0.01 or 0.05). When compared to the simvastatin group, the IR index and protein levels of LXRα in the Ilex asprella root group decreased (P < 0.05), and the serum adiponectin and SOD increased (P < 0.05).

CONCLUSIONThe Ilex asprella root decoction has some protective effects on regulating the related genes of lipid metabolism caused by chronic stress and hyperlipidemic fatty liver in rats.

OBJECTIVETo explore the therapeutic mechanisms of interferon-beta (IFN-beta) and intravenous immunoglobulin (IVIG) for experimental peripheral neuropathy induced by Campilobacter jejuni (Cj) lipopolysaccharide (LPS).

METHODForty healthy Wistar rats weighing 205 - 230 g were divided into IFN-beta, IVIG, IFN-beta plus IVIG and control groups. After the immune neuropathy was induced in the rats by Cj LPS, IFN-beta (1.3 microg/kg) was given by subcutaneous injection to the rats every other day for 6 weeks; IVIG [400 mg/(kg x d)] was given to the rats for five days, every other week for two times and IFN-beta [1.3 microg/(kg x d)] and IVIG [400 mg/(kg x d)] were given to the rats on the same days. Meanwhile, the control group was given PBS. The sera were collected in the 2nd, 4th and 6th week after therapy, the titers of anti-GM(1) IgG, MMP-9 and TNF-alpha in sera of immunized rats were measured by ELISA; histological study of sciatic nerve was performed and IgG on sciatic nerve was detected by immunohistochemistry in the 6th week.

RESULTS(1) There were no significant differences in titers of anti-GM(1) IgG, MMP-9 and TNF-alpha among the 3 therapeutic groups and control group after therapy for 2 weeks (P > 0.05). (2) The titers of anti- GM(1) IgG, MMP-9 or TNF-alpha in the control group were much higher than those of the IFN-beta group, the IVIG group or the IFN-beta and IVIG group after therapy for 4 weeks (P > 0.01) and there were no significant differences in titers of antibody among the 3 therapeutic groups (P > 0.05); the titers of MMP-9 or TNF-alpha in the IFN-beta and IVIG group were lower than those of the IFN-beta group or the IVIG group (P < 0.05). (3) The titers of anti-GM(1) IgG, MMP-9 or TNF-alpha in the control group were much higher than those of the IFN-beta group, the IVIG group or the IFN-beta with IVIG group after therapy for 6 weeks (P > 0.01); the IFN-beta with IVIG group had much lower levels of all indexes than the IFN-beta group or the IVIG group (P < 0.01).

CONCLUSIONIFN-beta and IVIG showed therapeutic effects on immune peripheral neuropathy through inhibiting the humoral and cellular immunity simultaneously in the peripheral neuropathy induced by CJ LPS, treatment with combined IFN-beta and IVIG was more effective.
