OBJECTIVETo observe the therapeutic effect and relevant mechanism of shuxuening Injection (SI) in treating patients with active ulcerative colitis (UC).

METHODSTotally 91 patients with active UC were randomly assigned to 2 groups, 44 in the control group and 47 in the treatment group. Patients in the control group received routine treatment, while patients in the treatment group additionally received intravenous injection of SI (15 mL), twice daily for 14 days in total. Colonoscopy was performed before and after treatment. The therapeutic effect was assessed by Mayo scoring system and the grading of activities evaluated by Baron endoscope. Serum levels of IL-6 and TNF-α were detected by ELISA. The activity of SOD was detected by xanthine oxidase method. The content of MDA was detected by thiobarbituricacid (TBA). Besides, 20 healthy subjects were recruited as the healthy control group.

RESULTSTotally 82 patients completed the study (40 in the control group and 42 in the treatment group). There was no statistical difference in serum levels of IL-6, TNF-α, SOD, MDA, the Mayo score and endoscope grading between the two groups before treatment (P >0. 05). Compared with the healthy control group, serum levels of IL-6, TNF-α, MDA significantly increased (P <0.01), and the serum SOD level decreased (P < 0. 05) in the treatment grup and the control group before treatment. Compared with before treatment in the same group, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased in the treatment group and the control group after treatment (P <0. 01, P <0. 05). Compared with the control group after treatment, serum levels of IL-6, TNF-α, MDA, the Mayo score and endoscope grading all decreased (P <0.01, P <0.05), the serum SOD level increased (P <0.05) in the treatment group after treatment. The serum SOD level was obviously negative correlated with serum levels of IL-6, TNF-a, Mayo score, and endoscope score (r = -0. 621, -0.638, -0. 509, -0.787, P <0.01). The serum MDA level was obviously positive correlated with serum levels of IL-6, TNF-α, Mayo score, and endoscope score (r =0.711, 0. 882, 0. 525, 0. 639, P <0.01).

CONCLUSIONSI could improve inflammatory injury and clinical symptoms of patients with active UC, and its mechanism might be associated with antioxidant and scavenging oxygen free radicals.

OBJECTIVETo investigate the anti-inflammation and anti-oxidation effects of recombinant human CuZn superoxide dismutase(rhSOD) on acute lung injury (ALI) induced by meconium aspiration in rats.

METHODS1 ml/kg of 20% human newborn meconium suspension was intratracheally (IT) administrated to induce the model of ALI in 32 male Sprage-Dawley rats, and the animals were then randomized to 4 groups: 3 treatment groups with IT administration of 5, 10 and 20 mg/kg rhSOD dissolved in 1 ml/kg saline and the control group with IT administration of 1 ml/kg saline. The animals were killed after 24 h of treatments. The measurements included lung tissue wet/dry ratio, broncho-alveolar lavage fluid (BALF) protein, BALF protein/plasma protein (pulmonary permeability index, PPI),lung myeloperoxidase (MPO) and superoxide dismutase (SOD) activity, nitric oxide (NO) and 8-isoprostane levels. Lung injury score was also evaluated.

RESULTSCompared with the control group, pulmonary MPO activity, NO and 8-isoprostane levels were significantly decreased and SOD activity was markedly increased in all rhSOD treatment groups (P<0.05 or 0.01). Compared with the rhSOD 5 mg/kg group, pulmonary 8-isoprostane level was further low in the rhSOD 20 mg/kg group(P=0.01). Lung injury score was decreased in rhSOD 20 mg/kg group (P<0.05). But there were no statistically differences in lung wet/dry, BALF protein and PPI among all groups.

CONCLUSIONThe results suggest that a single IT dose of 5,10 or 20 mg/kg rhSOD can prevent lung damages in rats with ALI following meconium aspiration.

OBJECTIVETo investigate the clinical characteristics and prognosis of patients with different subtypes of breast cancer: basaloid, HER-2 and luminal types, and try to find the evidence of individualized treatment for the patients.

METHODS1280 histologically and immunohistochemically proven patients with resectable breast cancer were treated, and the clinical data including characteristics, relapse and survival of the patients with different subtypes of breast cancer were analyzed retrospectively.

RESULTSOf the 1280 breast cancer patients, basaloid, HER-2 and luminal types accounted for 20.9%, 23.2% and 55.9%, respectively. Basaloid type was more likely to be found in younger patients frequently with a family history of breast cancer. HER-2 type usually had a tumor of larger size with more advanced stage disease and more metastatic lymph nodes. Luminal type was likely to occur in aged patients with an earlier stage disease. The recurrence rates in basaloid, HER-2 and luminal types were 25.0%, 27.9% and 11.7%, respectively. Patients with basaloid or HER-2 type were found to have a significantly higher recurrence rate than the patients with luminal type breast cancer (P < 0.001), but no significant difference was observed between the basaloid and HER-2 types. However, patients with basaloid type breast cancer were more likely to develop lung metastasis than HER-2 type (13.4% vs. 7.1%, P = 0.017). Up to December 2006, the 5-year disease-free survival (DFS) rates for patients with basaloid, HER-2 and luminal types were 72.2%, 68.2% and 86.2% (P < 0.001), respectively. The overall 5-yr survival (OS) rates of the three groups were 88.6%, 83.8% and 95.8% (P < 0.001) , respectively. Of the patients with luminal type breast cancer, HER2-negative patients had a higher DFS (86.2% vs 57.0%, P < 0.001) and OS (95.8% vs 87.7%, P = 0.0001) compared with those with HER2-positive. The results of Multivariate Cox Regression showed that tumor size and lymph node state were the most important factors influencing the prognosis.

CONCLUSIONEach subtype of breast cancer has somewhat its own specific clinical features in terms of recurrence pattern and prognosis, therefore, individualized treatment regimen may be required.

OBJECTIVETo identify the IgE-binding epitopes in the allergen Der p 1 of main house dust mites, which can be recognized by the specific IgE in the sera from allergic individuals, and obtain a hypoallergen derived from the T-B epitope fused peptide for potential use in specific immunotherapy (SIT).

METHODSThirty-one peptides containing 15 amino acids each, which covered the full 222 amino acids of Der p 1 protein sequence, were synthesized on the cellulous membrane by solid-phase peptide (SPOTs) synthesis, with 8 overlapping amino acids between every two neighboring peptides. The membrane bearing the spots of the synthesized peptides were incubated with the allergic serum pools consisting of the sera from 5 allergic individuals. The membrane was then probed with HRP-conjugated anti-human IgE, followed by enhanced chemiluminescence (ECL) for visualization and gray scale analysis of the positive peptide spots.

RESULTSThree strong IgE-binding epitopes were identified in the amino acid sequence of Der p 1 molecule, namely Ep1 (amino acids 85-99), Ep2 (amino acids 106-120) and Ep3 (amino acids 190-204).

CONCLUSIONThe 3 IgE-binding epitopes (B cell epitopes) identified in Der p 1 confirm the presence of linear epitopes in Der p 1, suggesting the possibility of constructing T/B epitope-fused hypoallergens.

Objective To explore the correlation between the change of regional cerebral blood flow (rCBF) and brain tissue injury from interictal epileptic activity in patients with epilepsy. Methods Fortyeight patients with epilepsy and 30 healthy persons were included in the styudy from which the serum S100β protein levels were determined by double antibody sandwich ELISA method. SPECT rCBF imaging was performed in all patients. The visal and semi-quantitative analyses were used to analyze the epileptic foci.SPSS 11.0 was applied for variance and linear correlation analyses. Results Serum S-100β in patients with interictal epileptic activity was significantly higher than that in control group ((0.572 ± 0. 163) μg/Lvs (0.218 ±0. 134) μg/L, t =9.96, P <0.01). According to epilepsy control criteria, 20 cases achieved complete control (CC), 18 cases acheived partial control (PR). However, 10 cases got no improvement,whose serum S-100β protein ((0. 809 ±0. 056) μg/L) and the percentage change of rCBF ((0. 337 ±0. 060) %) were significantly higher than those of CC ((0.443 ± 0. 083) μg/L, (0.035 ± 0.038) %) and those of PC ((0.585 ±0. 108) μg/L, (0. 187 ±0.075)%), F=56. 740, 92. 316, P <0.01. There were high correlation between serum S-100β and the percentage change of rCBF in epilepsy patients (r =0. 887,P<0.01). Conclusion Serum S-100β protein assay combined with rCBF on SPECT imaging can make semi-quantitative diagnosis of epilepsy and help evaluate the brain damage from interictal epileptic activity.
