Objective To investigate the clinical significance of antinucleosome antibody (AnuA) in the patients with lupus erythematosus (LE) through detecting the serum level of AnuA in different types of LE patients before and after treatment. Methods Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum level of AnuA in 31 SLE patients, 26 SCLE patients, 7 DLE patients, 6 scleroderma patients, 5 dermatomyositis patients and 30 healthy controls. Among them, the serum levels of AnuA before and after treatment were detected in 15 SLE patients and 10 SCLE patients. Clinical data, laboratory test results and the scores of SLE disease activity index (SLEDAI) were analyzed with SPSS11.0 software. Results The serum levels of AnuA in SLE patients were higher than those in SCLE, DLE, scleroderma, dermatomyositis patients and healthy controls(P

This study was aimed to analyze the major protein composition of centipedes (Scolopendra subspinipes mutilans L.Koch.), and the ACE inhibitory activity of its hydrolysis. Albumins, gulbulins, coixins and glutelins were sequentially extracted from centipedes flour with corresponding buffer and then quantified by Kjeldahl method and Brandford. Hydrolysation of four kinds of proteins of centipedes and the residues were conducted with pepsin. The hydrolysis was ultrafiltrated (MWCO=3 000) and lyophilized. The peptides (≤3 kD) were obtained to evalu-ate the ACE inhibitory activity by RP-HPLC. The results showed that the total protein content of centipedes was (62.69±1.41)%. Among which the contents of albumins, globulins, coixins, glutelins and residual were account-ing for (6.42±0.31)%, (7.94±0.24)%, (4.31±0.34)%, (40.66±0.56)% and (25.78±0.60)%, respectively. The inhibition rate of hydrolysis of four kinds of protein and residual were 50.28%, 57.37%, 31.15%, 58.99%, 80.81%, respectively. It was concluded that centipedes were rich in protein and the hydrolyzate of all proteins manifested ACE inhibitory activity at different extent. The residual and glutelins indicated strong ACE inhibitory potential by hydrolysis. This research provided valuable sights for exploring hypotensive activity and functional food from centi-pedes.

Objective To investigate the effects of different target effect-site concentrations (Ces) of remifentanil on the sedative effect of propofol. Methods Fifty ASA Ⅰ or Ⅱ patients aged 20-55 yr weighing 48-86 kg with body mass index < 30 kg/m2 were randomly divided into 5 groups ( n = 10 each) . Anesthesia was induced with TCI of remifentanil (Ce = 0, 2, 4, 6 and 8 ng/ml in groups R0-R4 respectively) and propofol. The initial Ce of propofol was 2.0 μg/ml in the 5 groups, and then the Ce of propofol increased by 0.5 μg/ml every 1 min until BIS value decreased to 50. BIS value and Ce of propofol were recorded as the patient lost consciousness. The effect-site concentration and consumption of propofol and the time required were recorded when BIS value decreased to 50.Results BIS value was significantly increased, while the effect-site concentration of propofol was significantly decreased as the patient lost consciousness, and the effect-site concentration and consumption of propofol were significantly decreased and the time required was shortened when BIS value decreased to 50 in R2-R4 groups compared with group R0 (P < 0.05 or 0.01) . Conclusion The sedative effect of propofol can be enhanced when the Ce of remifentanil reaches 4 ng/ml, and the effects are comparable when the Ce of remifentanil reaches 4, 6 and 8 ng/ml.

Objective To investigate the expression and significance of E-cadherin and β-catenin in type Ⅰ endometrial carcinoma.Methods The expression of E-cadherin and β-catenin were detected by immunohistochemistry in 60 patients with type Ⅰ endometrial carcinoma and 10 normal endometrial tissues.The patients were followed-up postoperatively for the survival rate.Results Expression of E-cadherin and β-catenin in 10 normal endometrial tissues was all high expression,while those of both abnormal expression in type Ⅰ endometrial carcinoma with expression rates with 60.0 % (36/60) and 55.0 % (33/60),respectively,which were difference compared with both in normal endometrial tissues (P < 0.05).The expression rates were markedly decreased in carcinoma with lymph node metastasis than those without lymph node metastasis.The proportions of abnormal expressions of E-cadherin and β-catenin were positively correlated with tumor grade and myometrial invasion in type Ⅰ endometrial carcinoma (P < 0.05).The postoperative two-year survival rate in the patients with abnormal expression of E-cadherin and β-catenin were much lower than those with normal expression (P < 0.05).Conclusions Abnormal high expression of E-cadherin and β-catenin may play important roles on generation and metastasis in type Ⅰ endometrial carcinoma.Both of them may be promising method for predicting invasion and metastasis and can be prognostic predictors in type Ⅰ endometrial carcinoma.

Objective To compare anti-inflammatory and hepatoprotective effects of Bupleurum marginatum Wall. ex DC. and Bupleurum chinense DC. Methods The anti-inflammatory effect of two kinds of radix bupleuri decoction were compared using the xylene-induced ear edema mice model and the egg white-induced foot swelling rats model. Acute liver injury in mice was induced through intraperitoneal injection of peanut oil with 0. 1%carbon tetrachloride. Alanine aminotransferase ( ALT ) , aspartate aminotransferase ( AST ) , and alkaline phosphatase ( ALP ) in serum, superoxide dismutase ( SOD ) , malondialdehyde ( MDA ) , and glutathione ( GSH ) in liver tissue homogenate were detected. Histopathological changes, transforming growth factor-β ( TGF-β) and nuclear factor-κB ( NF-κB) in hepatic tissues were also observed. Results Ear swelling experiment showed that the decoction of both Bupleurum marginatum Wall. ex DC. and Bupleurum chinense DC. had equal anti-inflammatory effects (P>0. 05). Similarly,the decoction of Bupleurum marginatum Wall. ex DC. and Bupleurum chinense DC. improved levels of ALT,AST,SOD,GSH,and MDA to the same extent compared with the model control group ( P<0. 05 or P<0. 01 ). There was no significant difference among all groups in ALP levels ( P > 0. 05 ). Histopathological and immunohistochemical experiments showed that expressions of TGF-β and NF- κB were similar between the two kinds of radix bupleuri. Conclusion Bupleurum marginatum Wall. ex DC. and Bupleurum chinense DC. have similar anti-inflammatory and hepatoprotective effects.

Objective To evaluate the effect of hydrogen (H2) inhalation on brain injury in septic mice.Methods One hundred and eighty male ICR mice,aged 6-8 weeks,weighing 20-25 g,were randomly divided into 4 groups (n =45 each) using a random number table:sham operation group (SH group),H2 group,sepsis group (S group) and sepsis + H2 group (S + H2 group).Sepsis was produced by cecal ligation and puncture (CLP) in chloral hydrate-anesthetized mice.H2 and S + H2 groups inhaled 2% H2 for 1 h starting from 1 and 6 h after CLP.At 7,12 and 24 h after CLP,6 mice in each group were sacrificed and brains were removed for determination of Evans Blue (EB) and water contents in brain tissues.Another 6 mice in each group were chosen at 7,12 and 24 h after CLP,blood samples were obtained,the mice were then sacrificed and brains were removed to measure the concentrations of tumor necrosis factor-α (TNF-α),high mobility group protein B1 (HMGB1) and interleukin-10 (IL-10) in serum and brain tissues by ELISA.Three mice in each group were sacrificed at 24 h after LPS and brains were removed for microscopic examination of pathological changes in hippocampal CA1 region.Six mice in each group were sacrificed at 24 h after LPS and brains were removed for determination of the expression of nuclear factor E2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) in brain tissues by Western blot.Results Compared with SH group,the contents of EB and water in brain tissues were significantly increased,and the levels of TNF-α,HMGB1 and IL-10 in serum and brain tissues were increased at 7,12 and 24 h after CLP,and the expression of Nrf2 and HO-1 in brain tissues was up-regulated at 24 h after CLP in S and CLP + H2 groups,and no significant difference was found in the index above in H2 group.Compared with S group,the contents of EB and water in brain tissues were significantly decreased,the levels of TNF-α and HMGB1 in serum and brain tissues were decreased and the level of IL-10 in serum and brain tissues was increased at 7,12 and 24 h after CLP,and the expression of Nrf2 and HO-1 in brain tissues was up-regulated at 24 h after CLP and the pathological changes were attenuated in group CLP + H2.Conclusion H2 inhalation can attenuate brain injury in septic mice and the mechanism is related to activation of Nrf2/ARE signaling pathway and inhibition of inflammatory responses.
