Objective To explore the biological mechanism of the Lingering Toxins Theory in ulcerative colitis (UC) by clinical trials. Methods Forty patients with UC at mild, moderate active stage and at remission stage were enrolled into the experiment. Twenty cases of UC patients at active stage were divided into Chinese medicine intervention group and western medicine treatment group, 10 in each group. Twenty cases of UC patients at remission stage were also evenly divided into Chinese medicine intervention group and western medicine treatment group. All patients were given conventional western medicine treatment, and additionally, Chinese medicine intervention group were given oral use of Chinese medicine decoction, the treatment course covering 8 weeks. Before and after treatment, plasma matrix metalloproteinase-1 (MMP -1), tissue inhibitor ofmetalloproteinase-1 (TIMP-1) and prostaglandin E2 (PGE2) expression levels were observed by enzyme-linked immunosorbent assay (ELISA) . Results Plasma MMP-1,TIMP-1, and PGE2 expression levels in UC patients were positively correlated with disease severity (P<0.001) . After treatment, the expression levels of MMP-1, TIMP-1, and PGE2 in active-stage patients of both groups were decreased compared with those before treatment (P<0.001) , but the difference between the two groups was insignificant ( P>0.05) . After treatment, the expression levels of MMP-1 and TIMP-1 in remission-stage patients of Chinese Medicine intervention group were decreased (P<0.001) , and the decrease was superior to that of Western medicine treatment group (P<0.05) . Difference of PGE2 expression level in remission-stage patients of both groups was insignificant ( P>0.05) . Conclusion There is a relation between plasma MMP-1, TIMP-1 expression levels and the “lingering toxins” in the field of traditional Chinese medicine. The biological mechanism of toxins-removing therapy in treating UC may be associated with the decrease of the plasma MMP-1 and TIMP-1 expression levels.

ObjectiveTo observe the effect of recombinant human interleukin-11 combined with ciclosporin in treatment of giucocorticoid invalid idiopathic thrombocytopenic purpura.MethodsFrom August 2009 to August 2011,35 cases with glucocorticoid invalid idiopathic thrombocytopenic purpura patients were divided into two groups according to the treatment method:13 cases in control group were treated with ciclosporin and 22 cases in observation group were treated with recombinant human interleukin-11 at basis of above method.The clinical effect and platelet counts between two groups were compared.Results The total effective rate in observation group was 90.9％ (20/22),which was significantly higher than that in control group [53.8％ (7/13)] (P ＜0.05).After treatment,the platelet counts in both two groups were significantly increased [control group:( 112.5 ± 15.4) × 109/t vs.(13.2 ± 1.8 ) × 109/L; observation group:( 132.7 ± 22.3 ) × 109/L vs.(12.9 ± 1.6) × 109/L] (P ＜ 0.05 ).Moreover,the platelet counts after treatment in observation group was significantly more than that in control group (P ＜ 0.05).ConclusionRecombinant human interleukin-11combined with ciclosporin in treatment of glucocorticoid invalid idiopathic thrombocytopenic purpura is a good treatment scheme,which can be applied in clinic.

Objective:To summarize endoscopic management of cerebrospinal rhinorrhea and position-determining means.Method:Fifteen cases of cerebrospinal rhinorrhea treated by endoscopic approach at our institution were analyzed retrospectively.Aetiology included accidental trauma (10), surgical trauma (4), idiopathic (1). All patients presented with CSF rhinorrhea.Six cases were operated after failure of conservative treatment. Two cases after failure of neurosurgical repair were referred to our department. The largest defect was as big as 2.5 cm×1.5 cm. All patients were scanned by computed tomography and magnetic resonance imaging and confirmed by biochemistry test.Ten patients received high resolution spiral computed tomography bonding ventriculography.Result:We performed intranasal endoscopic repair in all 15 patients. All repairs were successful at the first attempt with a mean follow up of 20 months. One patient had light headache postoperatively and relieved with conservative treatment. All defects of skull base detected by computed tomography and ventriculography were confirmed in the operation.Conclusion:Intranasal endoscopic repair of cerebrospinal rhinorrhea can be an effective method. High resolution spiral computed tomography scan combined with ventriculography is a precise position-determining means. With the advancement of instrument and operative skill,the scope of endoscopic repair will further extend.

Objective To investigate the effect of γ-glutamylcysteine synthetase (γ-GCS),in the kidney fibrosis of MRL/lpr lupus mice.Methods The expression of connective tissue growth factor(CTGF)and γ-GCS in the kidney tissue of MRL/lpr lupus mice and control mice were detected by reverse transcriptase PCR (RT-PCR)and immunohistochemistry.The relationship between CTGF and γ-GCS was analyzed.Results The transcription and expression of CTGF in the kidney tissue of MRL/lpr lupus mice was significantly higher as compared with that of the control mice(CTGF mRNA:1.052±0.004 vs 0.402±0.009,P<0.01;CTGF protein:3.364±0.460 vs 1.206±0.271,P<0.01);whereas the expression of γ-GCS mRNA was decreased in MRL/lpr lupus mice(0.952±0.011 vs 1.145±0.066,P<0.01).Pearson's regression analysis showed that there was a negative correlation between CTGF and γ-GCS(r=-0.902,P<0.01).Conclusion The decreased expression of γ-GCS in the kidney of MRL/lpr lupus mice may compromise the ability of antioxidative stress,and there is a negative correlation between γ-GCS and CTGF.This suggests that the perturbation of γ-GCS may contribute to the progress of kidney fibrosis.
