Objective To observe the effect of Xuebijing injection on the expression of tumor necrosis factor-alpha (TNF-α) and high mobility group box-1 protein (HMGB-1) in rat peritoneal mesothelial cells (PMCs) induced by lipopolysaccharide (LPS). Methods PMCs were isolated from rat colic omentum and the 3rd generation cells were used in the experiment. PMCs were incubated with LPS at different concentrations (1,10,100 mg/L);with LPS (10 mg/L) for 2, 6, 12, 18, 21, 24, 36 h;with Xuebijing injection at different concentrations (2,10,20 g/L) after incubation with LPS (10 mg/L) for 2 h. PMCs in the control group were incubated with medium. HMGB-1 mRNA was detected by RT-PCR. TNF-α and HMGB-1 protein in supernatants was detected by ELISA. Results Compared to the control group, the expression of HMGB-1 mRNA and protein was significantly increased in groups stimulated by LPS in a time- and dose-dependent manner (all P<0.05);the expression of TNF-α was increased in the groups stimulated by LPS in a dose-dependent manner (P<0.05). In the groups stimulated by LPS (10 mg/L), the expression of TNF-α appeared double hump within 36 hours. Compared to LPS (10 mg/L) group, Xuebijing injection significantly inhibited the expression of HMGB-1 and TNF-α (all P<0.05 ) in a dose-dependent manner. Conclusions HMGB-1 as a late mediator of inflammatory responses may play a role in the pathogenesis of peritoneal dialysis related peritonitis. Xuebijing injection can reduce peritoneal inflammatory impairment by inhibiting the up-regulation of TNF-α and HMGB-1 induced by LPS.

However, it could not be influenced on mild sperm abnormalities.

Objective To investigate the changes of cardiac function at pre -and post -treatment in preterm infants with patent ductus arteriosus (PDA)in order to guide drug treatment.Methods Totally 84 preterm infants with PDA admitted to Neonatal Intensive Care Unit of Xuzhou Hospital Affiliated to Medical College of Southeast University from July 201 2 to June 201 4 were divided into 4 groups according to treatment drug:Ibuprofen group (27 cases),Indo-methacin group (24 cases),control group (1 1 cases),and Paracetamol group (22 cases).Patients were also divided into symptomatic PDA group (38 cases)and asymptomatic PDA group (46 cases)according to severity;PDA closed group (69 cases)and PDA unclosed group (1 5 cases)according to sequel.The level of plasma brain natriuretic pep-tide (BNP),cardiac troponin I (cTnI),correct QT intervals dispersion (QTcd)were monitored pre -and post -treat-ment.Data were analyzed by using SPSS 1 9.0 software.Results Three cardiac markers at post -treatment were of no significant difference among 4 treatment drugs.The changes of the cTnI and QTcd at pre -and post -treatment were of no significance.The level of BNP in symptomatic PDA group was significantly higher than that in asymptomatic PDA group at pre -treatment [(378 ±94)ng/L vs (1 47 ±75)ng/L,t =2.584,P =0.01 4].In the symptomatic PDA group,the level of BNP at post -treatment [(1 82 ±81 )ng/L]was significantly decreased than that at per -treatment (t =2.741 ,P =0.009).In the asymptomatic PDA group,there was no significant difference between the pre - and post -treatment [(1 21 ±61 )ng/L]in the level of BNP (t =1 .254,P =0.207).There was no significant difference in the level of BNP at per -treatment between PDA closed group and PDA unclosed group [(274 ±91 )ng/L vs (289 ± 87)ng/L,t =-0.874,P =0.391 ].In PDA closed group,the level of BNP at post -treatment [(1 21 ±74)ng/L] was significantly decreased compared with that at per -treatment (t =3.580,P =0.000).In PDA unclosed group, there was no significant difference between the pre - and post -treatment [(245 ±74)ng/L]in the level of BNP (t =0.854,P =0.392).Conclusion Early medication intervention for symptomatic PDA of preterm infants is benefi-cial for the closure of PDA and for attenuating negative effects on cardiac function of PDA.

Objective To investigate the effects of curcumine treatment on the expression of TNF-α in the peritoneum of acute peritonitis rats. Methods The rats were intrapertoneally injected Staphylococcus epidemidis (S.epidermidis) for the mixlelization of acute peritonitis. After a survival time of 3,6,12,24 and 48 hours,TNF-α expression in the peritoneum was detected by Western blot and RT-PCR in the rats of curcumin treatment group and non-curcumin treatment group. Results TNF-a expression showed time-dependent increase at 6,12,24 hours after the infection in the non-curcumin treatment group. In curcumin treatment group,TNF-α expression decreased at 6,12,24 hours after infection compared to non-curcumin treatment group. Conclusion Curcumin may be a protective agent in acute peri-tonitis induced by S.epidermidis.

Objective To detect Helicobacter pylori (H.pylori) multiple antibodies of urease (Ure),cytotoxin associated gene A protein (CagA),vacuolating toxin A (VacA),heat shock protein 60 (Hap60) and nitroreductase ( RdxA),and disclose their relations with chronic gastritis,peptic ulcer and gastric cancer.Methods A volume (3 ml) of venous blood was taken from 300 patients of gastroduodenal disease diagnosed by endoscopy,to centrifuge and detect antibodies of Ure,CagA,VacA,Hsp60,RdxA by protein chip technique.Results The infective rates of H.pylori in chronic gastritis,peptic ulcer,and gastric cancer were 34.0％,58.0％,34.0％ ( P ＜ 0.01 ),respectively.In the H.pylori positive chronic gastritis,peptic ulcer and gastric cancer,the positive rates of CagA antibody were 54.9％,75.9％,64.7％ ( P =0.070) ; the positive rates of VacA antibody were 31.4％,22.4％,17.6％ ( P =0.412) ;and the positive rates of Hap60 antibody were 56.9％,48.3％,41.2％ ( P =0.466),respectively.The total positive rate of RdxA antibody was 4.0％ (5/126).Conclusions H.pylori infection and virulence factor CagA are closely related to peptic ulcer,while it did not show the exact correlation between VacA,Hsp60 and gastroduodenal disease.The level of RdxA antibody can not represent the level of H.pylori resistance to metronidazole.

[ ABSTRACT] AIM:To investigate the expression and regulation of A20 in healthy individuals and the patients with systemic lupus erythematosus (SLE).METHODS:The expression levels of A20, NF-κB, MALT1, and MALT1V1 in peripheral blood mononuclear cells ( PBMC) of the patients with SLE ( including 2 cases with scleroderma, 1 case with rheumatoid arthritis, and 1 case with lymphoma) were analyzed by real-time PCR.RESULTS:A significantly lower A20 expression level was found in the PBMC from SLE group compared with the healthy controls, while the expression levels of MALT1 and NF-κB were also decreased.In addition, no significant correlation between A20 and NF-κB expression levels in healthy group was observed, but a positive correlation was found in SLE group ( P<0.05) .A significant positive corre-lation between MALT1 and NF-κB expression levels in healthy group ( P<0.05) was observed, and no significant correla-tion was found in SLE group.The expression level of MALT1V1 in SLE group was significantly lower than that in healthy control group, and there was a positive correlation between A20 and MALT1V1 in healthy volunteers (P<0.01), but that did not exist in SLE group.CONCLUSION: The characteristics of the expression pattern of MALT1-A20-NF-κB in the SLE patients were presented.Lower level of A20 expression was found in the SLE patients, in particular with other autoim-mune disease or lymphomas, indicating the lower immune tolerance in SLE.The positive correlation of A20 and NF-κB may relate to positive regulation of MALT1.
