Objective:To observe the curative effects of the combined application of domperidone, pantoprazole and hydrotalcite tablets in the treatment of bile reflux gastritis ( BRG) and explore the underlying mechanism. Methods:Totally 80 patients with BRG were randomly divided into the treatment group and the control group with 40 cases in each. The treatment group was received panto-prazole, hydrotalcite tablets and domperidone, and the control group was treated by hydrotalcite tablets and domperidone. The efficacy was observed in both groups after 4 weeks. Results:The effective rate of symptom relief in the treatment group and the control group was respectively 92. 5% and 62. 5% (P<0. 05). After the 4 week treatment, the gastritis healing rate in the treatment group was higher than that in the control group (P<0. 05). The improvement of gastric mucosal hyperemia, edema and erosion in the treatment group was better than that in the control group with significant difference (P<0. 05). Cholic acid in gastric juice and gastric acid se-cretion were significantly reduced in both groups after the treatment, while the reduction of gastric acid secretion in the treatment group was more notable than that in the control (P<0. 05). Conclusion:Pantoprazole can be used to control BRG, and the combination of the three drugs shows better efficacy in the treatment of BRG.

Objective To explore the diagnostic significance of CT and MRI in dermatofibrosarcoma protuberans.Methods Analyze the CT and MRI images of 16 cases which were confirmed as dermatofibrosarcoma protuberans by pathology.The medical imaging features of dermatofibrosarcoma protuberans were summarized.In the total 16 cases(including 6 male cases,10 female cases),15 cases had suffered from dermatofibrosarcoma protuberans for more than 1 year, 11 cases for more than 5 years, and 9 cases had history of recurrence.Results On MRI, the mass was slightly hypointense on T 1 WI, inhomogeneously hyperintense on T 2 WI with inhomogenous enhancement.The diameters of mass were less than 5 cm in 3 cases,and were more than 5cm in 13 cases.Fifteen cases had clear demarcation between the masses and their adjacent muscles , 7 cases had “suspension sign” in shapes, 10 cases had “sub-nodules outward” features at the edge of the tumors , 12 cases had “multinodular” features inside the tumor , and 8 tumors grew into the surrounding fat layer like roots.Conclusion Dermatofibrosarcoma protuberans can be diagnosed accurately based on the features displayed on CT and MRI.

AIM To aim at investigating the function of Kaixin Jieyu Pills (Ginseng Radix et Rhizoma,Bupleuri Radix,Morindae officinalis Radix,etc.) to vascular depression and their mechanism of action.METHODS A vascular depression model of rat was established by chronic unpredictable mild stress and separation after ligation of the bilateral common carotid arteries.The rats were treated with Kaixin Jieyu Pills and fluoxetine hydrochloride (FLU) for 28 days,respectively.The sucrose preference test and open-field test were performed.Cerebral perfusion was investigated with a Perfusion Speckle Imager.The monoamines including serotonin,dopamine and noradrenaline,and brain-derived neurotrophic factor (BDNF) were determined with ELISA and Western bolt,respectively.RESULTS Kaixin Jieyu Pills significantly increased sucrose preference,moving distance and cortical blood flow.Kaixin Jieyu Pills could upregulate,to different extents,the expressions of monoamines,including serotonin,noradrenaline and dopamine,and BDNF.Kaixin Jieyu Pills had a function similar to FLU in behavior,upregulating monoamines and BDNF,but it is superior to FLU in cortical blood flow.CONCLUSION Kaixin Jieyu Pills has the advantage of reducing the depression-like behavior and improving cerebral hypoperfusion,which might be mediated by the upregulation of the serotonin,noradrenaline and BDNF.

Objective To explore the role of dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN) in the tubulointerstitial lesions of immune-mediated nephrotoxic nephritis (NTN) and the intervention regulation by anti-P-selectin lectin-EGF domain monoclonal antibody (PsL-EGFmAb). Methods WKY rats were randomly divided into control,NTN and PsL-EGFmAb-treated groups. The mrs in NTN group were injected with 1 ml nephrotoxic rabbit serum per kilogram of rat body weight; the ones in PsL-EGFmAb-treated group were injected with 2 mg PsL-EGFmAb per kilogram of rat body weight simultaneously and 2 h later after nephrotoxic rabbit serum injection; and those in control group were injected with equal volume of 0.9% saline. Renal function and pathology were observed at day 4, 7 and 14 after the induction of NTN. Distribution of DC-SIGN + dendritic cells (DCs) in renal tissues was measured by immunofluorescence. Real-time PCR was performed to examine the expression of P-selectin,RANTES, TNF-α, IL-10, IFN-γ and IL-4. Expression of MHC Ⅱ , CD80 and DC-SIGN on dendritic cells was analyzed by flow cytometry. Transendothelial migration was used to detect the ability of DCs migration. DCs ability to activate T cells was determined by mixed lymphocyte reaction (MLR). ELISA was used to detect the concentration of IFN-γ and IL-4 in the supernatant of MLR. Results At day 4, immature DC-SIGN+ DCs infiltrated the rat renal tubulointerstium of NTN group, matured at day 14, and enhanced the ability to migrate and activate T cells. The distribution of DC-SIGN + DCs was significantly related to the form of crescent, tubulointerstial lesions and renal function. In addition, expression of chemokine RANTES and proinflammatory cytokine TNF-α continuously augmented since day 4, while anti-inflammatory eytokine IL-10 decreased after markedly increased at day 4. At day 14, IFN-γ/IL-4 mRNA increased, which was obviously related to DCs maturation. The intervention of PsL-EGFmAb supressed the expression of DC-SIGN and CD80 on DCs, depressed DCs maturation, migration and ability to activate T cells,down-regulated proinflammatory cytokines and up-regulated anti-inflammatory cytokines in kidney,and thus regulated Th1/Th2 bias. At the same time, kidneys showed the decrease of crescents,improvement of tnbulointerstium damage and renal function. Conclusions DC-SIGN may mediate DCs tubulointerstitial infiltration. It may be also a potent regulator of local immune reaction imbalance and pathology of tubulointerstium. PsL-EGFmAb may depress DCs migration and downregulate DCs maturation and function through DC-SIGN, and thus having a role in prevention and treatment.
