Objective To investigate the role of CD4+ CD25+ regulatory T lymphocyte(Tregs)in the immunological pathogenesis of liver fibrosis.Methods Twenty-six rats were divided into two groups:control group(6 rats)and model group(twenty rats).The rat model of liver fibrosis was induced bv subcutaneous injection of carbon tetrachloride(CCl4).The serums were collected for detection of hepatic function and fibrosis parameters.Hepatic tissue samples were used to observe the histopathological changes.The flow cytometry was used to detect the proportions of Tregs in both peripheral blood and spleen.The data were evaluated by t-test.The relationship between two variables was analyzed using Pearson linear correlation.Results The levels of serum alanine aminotransferase (ALT)and aspartate aminotransferase (AST) were significantly increased,but the level of serum albumin (Alb) was obviously decreased.The concentrations of serum hyaluronic acid (HA),procollagen type Ⅲ(PCⅢ),collagen type Ⅳ(CⅣ)of the model group increased to(177.42±61.25)μg/L,(34.86±7.47)μg/L and(7.32±3.71)μg/L,respectively,which were higher than those in the control group(t=-3.670,-5.661,-3.950,respectively;all P<0.01).In model group,hepatic lobules were full of collagen fibers and the hepatic pseudolobule formation was observed.The proportion of peripheral blood Tregs in CD4+ T lymphocyte in liver fibrosis model was(7.41±2.15)%,which was significantly lower than that in control group(12.88±2.93)%(t=3.752,P<0.01).Furthermore,the frequency of Tregs in spleen of the model group was(9.49±1.16)%,which was also significantly lower than that in control group(13.16±2.36)%(t=2.793,P<0.05).In addition,the levels of serum ALT,AST and fibrosis parameters were inverselv correlated with the frequency of Tregs in spleens and peripheral blood(ALT and Tregs in blood:r=-0.727,AST and Tregs in blood:r=-0.698,ALT and Tregs in spleen:r=-0.663,AST and Tregs in spleen:r=-0.535,HA and Tregs in blood:r=-0.719,PCⅢ and Tregs in blood:r=-0.558,CⅣ and Tregs in blood:r=-0.792,HA and Tregs in spleen:,r=-0.424,PCⅢ and Tregs in spleen:r=-0.685,CⅣ and Tregs in spleen:r=-0.506;all P<0.05).However,the linear correlations between serum Alb and Tregs in spleens and peripheral bloods were not observed(r=0.423,0.372,respectively,both P>0.05).Conclusion These findings suggest that the reduction of CD4+ CD25+ Tregs probably play an important role in the immunological pathogenesis of liver fibrosis.

Objective To study the protective role of ulinastatin in acute liver failure (ALF) and the effect on the expression of hemeoxygenase-1 (HO-1).Methods Sixty-six S-D rats were divided into three groups:control group,ALF group (model group) and ulinastatin group (intervention group).The rat model of ALF was induced by intraperitoneal injection of D-galactosamine (D-Gal) and lipopolysaccharide (LPS). The serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and malondialdehyde (MDA) were detected dynamically after 6,12,24,36 and 48 h injection.HO-1 mRNA expression in liver tissue was determined by reverse transcriptionpolymerase chain reaction (RT-PCR), and the expression of HO-1 protein was detected by immunohistochemistry.The differences among multiple groups were compared by univariate ANOVA and pairwise comparison was done by least significant difference (LSD). Results D-Gal/LPS injections successfully induced ALF rat model which presented with elevated levels of serum ALT,AST and liver MDA after 6 h injections (F=23.864,38.446,18.051,respectively,all P＜0.01),and peaked at 12-24 h after injections.Twenty-four hours after D-Gal/LPS treatment,the levels of serum ALT,AST and MDA in model group and intervention group were (8 346.7±1 363.1) U/L vs(4 151.3±970.0) U/L,(9 766.7±1.274.1) U/L vs (4 696.7±1 476.9) U/L,(8.34±1.13)μmol/g vs (4.66±0.91 ) μmol/g,respectively,which were significantly higher than those e (24.0±2.0) U/L,(82.3±16.9) U/L,(2.55±0.22) μmol/g,respectively] in control group (F=55.684,55.501,47.843,respectively,all P＜0.01);while those in intervention group were much lower than those in model group (P＜0.01).The expressions of HO-1 mRNA and protein in model group were significantly increased than those in control group (P＜0.01),while those in intervention group were even higher (P＜0.01).Conclusion Ulinastain could up-regulate the expressions of HO-1 mRNA and protein,which indicates that ulinastain may play anti-oxidant and anti-inflammatory roles in ALF through HO-1 pathway.

Objective To investigate the expression of Notch 1 receptor in renal tissues of patients with hepatitis B virus associated-glomerulonephritis (HBV-GN) and its role in the pathogenesis of HBV-GN.Methods A total of 48 patients with HBV-GN confirmed by renal biopsy during 2008-2010 were enrolled in the study.Distribution of Notch1 receptor in renal tissue of HBV-GN was detected by immunohistochemistry and the association between the distribution of Notch1 receptor and HBsAg was examined by double-label immunofluorescence assays.Correlations of Notch1 receptor expression with renal pathology and clinical parameters of HBV-GN were analyzed.Results Notch1 receptor distributed mainly in renal tubular epithelial cells and interstitial area as brownish red granules,and a few expression in glomerulus was also found.The positive score of Notch1 receptor expression in HBV-GN patients was significantly higher as compared to primary glomerulonephritis patients with serum HBsAg positive or negative and normal renal tissue controls.Notch1 receptor expression was more obvious in membrano-proliferative glomerulonephritis (MPGN) and mesangial proliferative nephritis (MsPGN) patients,but there was no significant difference among the different pathology groups.Distribution of Notch1 receptor was consistent with the distribution of HBsAg and its intensity was positively correlated with renal interstitial fibrosis (r=0.473,P=0.001),tubular atrophy (r=0.690,P=0.000),inflammatory cell infiltration (r=0.616,P=0.000).Negative correlation was found between renal function and the intensity of Notch1 receptor (r=-0.393,P=0.006).Conclusions Notch1 receptor expression increases in the renal tissues of HBV-GN patients and distributes mainly in renal tubular epithelial cells and interstitium,which is consistent with the distribution of HBsAg.Its intensity is closely correlated with renal interstitial lesions and renal function.Abnormal expression of Notchl receptor in renal tissue of HBV-GN may be involved in the progress of HBV-GN.

ObjectiveTo investigate the expression and distribution of Toll-like receptor 4 (TLR4) in renal tissue of HBV associated nephropathy (HBV-GN) and its role in the pathogenesis and clinical manifestations of HBV-GN.MethodsRenal tissues were sampled from 48 HBV-GN patients confirmed by renal biopsy and 154 non-HBV-GN patients.The distribution of TLR4 in renal tissue and the relationship between the distribution of TLR4 and HBsAg were detected by immunohistochemistry.Integrating case record,correlations between the expression of TLR4 with clinical parameters including pathology,glomeruli,kidney tubules lesions,renal interstitial inflammatory infiltration and blood serum HBV were analyzed.ResultsTLR4 mainly distributed in the renal tubular epithelial cells and interstitial areas as brownish red and granular,which was in consistent with HBsAg distribution.The TLR4 positive rate and score in HBV-GN group were higher than those in non-HBV-GN group (P ＜ 0.05 ).TLR4 positive score was slightly higher in mesangial proliferative glomerulonephritis group and focal segmental glomerulosclerosis group,which had no significant difference (P ＞ 0.05).Kidney tubules lesions were strongly associated with TLR4 expression (r =0.748,P ＜ 0.001 ) which increased with aggravation of renal interstitial fibrosis ( r =0.569,P ＜0.001 ),tubular atrophy ( r =0.577,P ＜ 0.001 ) and inflammatory cell infiltration ( r =0.684,P ＜0.001 ).No obvious correlation with glomeruli lesions was observed ( r =0.293,P =0.053 ).Negative correlation could be seen between TLR4 and the renal function ( R2 =0.784),systolic blood pressure ( R2 =0.869),high sensitivity C-reactive protein (R2 =0.979) and urinary protein (R2 =0.615 ) by regression analysis.Other clinical parameters had no statistical significances.ConclusionsThe expression of TLR4 is abnormal in the renal tissue of HBV-GN patients,mainly in renal tubular epithelial cells and interstitial,which is consistent with the distribution of HBsAg.Its intensity is closely related with renal interstitial lesions,renal function changes and inflammatory cell infiltration.A speculation,that HBV can promote abnormal expression of TLR4 in renal tissues of HBV-GN which may be involved in the lesion progress of HBV-GN,is made upon our study.

Objective:To review and analyze the prescriptions for Chinese herbal pieces in an integrative traditional Chinese and western medicine hospital to explore the trend and problems in clinical application for Chinese herbal medicines and provide reference for dispensing in pharmacy of traditional medicine and rational drug use. Methods: Totally 1200 prescriptions for Chinese herbal pieces in our hospital were surveyed from January to December in 2014. The irrational use was analyzed, and reasonable suggestions were provided for the clinical application. Results:The problems in the prescriptions for Chinese herbal pieces included uncompleted diagnosis,incompatible diagnosis and medication,nonstandard Chinese name,unclear footnote,irrational usage or dosage and incompati-bility. The prescriptions including above 15 varieties of Chinese herbal pieces in one accounted for 65. 70%, and those with average dose above 250 g accounted for 40. 25%. Conclusion:Regular inspection and quality supervision on the prescription for Chinese herb-al pieces should be strengthened to improve the quality of prescriptions and guarantee the safety and economy of the medication.

AIM:To generate monoclonal antibodies against human augmenter of liver regeneration (rhALR). METHODS:After BALB/C mice were immunized by the purified rhALR, the cells of spleen were fused with the cells of SP2/0; The titer and speciality were respectively fathomed from ascites or foster fluid by ELISA and Western-blot test. RESULTS:2 hybridoma cell lines were successfully obtained. The McAbs titer from ascites and foster fluid are respectively about 10-3-10-5 and 10-2-10-3. It is evident that the two McAbs were directed at different epitopes. CONCLUSIONS:The McAbs have higher speciality. It is significantly useful of the value that how hALR distribute in tissue organs, how the hALR signals the metabolism in the body and the control distribution of the hALR on cell growth on the translational level and so on is researched.

Objective To investigate the protective effects of elctroacupuncture(EA)at Zusanli(ST36) points on intestinal villas damage and mucosal permeability induced by small intestine pro-inflammatory factors in rats with intestinal ischemia/reperfusion(I/R). Methods 30 Sprague-Dawley(SD)rats were randomly divided into three groups(each,n=10):intestinal I/R group(model group),intestinal I/R+EA ST36 group(EA group)and intestinal I/R+sham EA group(SEA group). Rats were subjected to superior mesenteric artery(SMA)clamping at its root part to occlude the vessel for 30 minutes,followed by reperfusion for 60 minutes to form intestinal I/R models. Rats in EA group received EA at the bilateral ST36 points(2-3 mA,2-100 Hz)for 30 minutes immediately after ischemia,those in SEA group received EA at bilateral sham points(the point was located at 0.5 cm away from ST36 point in its lateral side)with the same frequency and intensity of stimulation as EA group for 30 minutes,and those in model group received no treatment. Animals were sacrificed 60 minutes after reperfusion and segments of distal part of ileum were harvested,then the levels of tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)in intestinal tissue were measured. Histopathologic changes were viewed and graded via light microscopy. A solution of fluorescein isothiocyanate(FITC)-dextran was injected into the lumen of the segment of intestine 30 minutes after reperfusion,systemic blood was drawn via abdominal aorta puncture at 60 minutes after reperfusion,and then the level of FITC-dextran in blood was measured to determine the changes in intestinal permeability. Results Compared to the model group and SEA group,EA ST36 significantly attenuated intestine TNF-α(pg/mg:3.01±0.50 vs. 8.65±1.02,8.42±1.41,both P<0.05)and IL-6 levels(pg/mg:2.51±0.15 vs. 6.34±0.86,6.13±1.12,both P<0.05),successfully maintained low gut injury scores(1.50±0.33 vs. 3.18±0.39,3.04±0.37,both P<0.05), and significantly reduced permeability of the distal ileum and the content of FITC-dextran(μg/L:282.42±73.92 vs. 856.22±229.47,844.22±239.47,both P<0.05). However,there were no significant differences in all above variables between SEA and model group(all P>0.05). Sections of distal ileum from animals in the model group and SEA group showed no obvious difference histologically,and the pathological manifestations were villous tip necrosis, blunt-shaped and collapse. Compared to the model group and SEA group,the intestinal villous injury in animals of EA group was much milder. Conclusion In rats with intestinal I/R injury,EA ST36 points has protective effect on the gut that is possibly due to the fact it may obviously lower the levels of the pro-inflammatory factors of small intestinal tissue,alleviate mucosal insult of gut and reduce the mucosal permeability.
