Objective To improve the rheumatologists' understanding of noncirrhotic portal hypertension.MethodsA case of systemic sclerosis complicated by noncirrhotic portal hypertension was reported and the related literatures were reviewed.Results A 51-year-old female who had been diagnosed as systemic sclerosis presented clinically with an chronic onset of portal hypertension.She also had pancytopenia,splenomegaly,and significant esophageal varices.Liver function tests were normal.Hepatitis viral serology was negative.Ultrasound scan of liver revealed no focal lesion.ACT scan confirmed the absence of portal vein thrombosis.Taking into account the above evaluation we concluded that the patient had systemic sclerosis and noncirrhotic portal hypertension.The patient was on prednisolone and immunosuppressant and the condition was well.Conclusion Noncirrhotic portal hypertension complicated by autoimmune disease,especially SSC,is very poor,characteriged by significant portal hypertension as well as histological evidence that cirrhosis is absent.Rheumatilogist should pay attention to it.

ObjectiveTo explore the effect of community based rehabilitation on chronic schizophrenia. Methods60 patients of chronic schizophrenia were randomly divided into the community based rehabilitation group (the study group) and the inpatients group (the control group). The study used prospective design for 1 year with brief psychiatric rating scale (BPRS),nurses' observation scale for inpatients evaluation (NOSIE) and social disability screening schedule (SDSS).ResultsCompared with the control group at the end of 6 month and 1 year, scores of BPRS, NOSIE and SDSS in the study group were significantly different (P<0.05-P<0.001). The relapse rate of the study group (0%) also lowered than that of the control group( 20%).ConclusionsCommunity based rehabilitation therapy can control the chronic schizophrenia effectively. It also promotes the life quality and social function of patients, and lowers the relapse rate significantly. It is an important rehabilitation method for chronic schizophrenia.

OBJECTIVETo compare the efficacy and safety between cryoablation (Cryo) and radiofrequency (RF) ablation for treating patients with atrioventricular nodal reentrant tachycardia (AVNRT).

METHODSPatients with AVNRT (n = 304) were divided into Cryo group (n = 67) and RF group (n = 237). The procedure success rate, complete slow pathway block rate, atrioventricular block rate and relapse rate were compared between two groups.

RESULTSThere was no statistically difference between 2 groups in the success rate (Cryo group 98.5% vs RF group 97.0%, P = 0.820), complete slow pathway block rate (Cryo group 98.5% vs RF group 91.6%, P = 0.088), atrioventricular block rate (Cryo group 0 vs RF group 2.5%, P = 0.413), relapse rate (Cryo group 0 vs RF group 1.7%, P = 0.643). But Cryo group had more advantage than RF group.

CONCLUSIONEfficacy and safety were comparable between cryoablation and radiofrequency ablation for treating patients with AVNRT.

OBJECTIVETo investigate the expression of heparin-binding epidermal growth factor-like growth factor (HB-EGF) in patients with gastric carcinoma in different stages.

METHODSThe expressions of HB-EGF protein and mRNA in normal gastric tissues, metaplasic intestinal mucosa, early-stage gastric cancer and advanced-stage gastric cancer tissues were detected by immunohistochemistry and in situ hybridization.

RESULTSHB-EGF expression was only detected in the parietal cells of the gastric fundic glands and in gastrin cells of the pyloric glands in normal gastric tissues. Weak HB-EGF expression was detected in the epithelial cells of the gastric mucosa in intestinal metaplasic mucosa, and the expression increased in all layers of the gastric mucosa in early-stage gastric cancer. Intense HB-EGF expression was observed in advanced gastric cancer.

CONCLUSIONIncreased HB-EGF expression may be implicated in the pathogenesis and development of gastric carcinoma.

OBJECTIVETo produce neutralizing antibodies against envelope protein domain III (EDIII) of dengue virus serotype I (DENV-1) and evaluate the nonstructural protein 1 (NS1) antigen capture enzyme-linked immunosorbent assay (ELISA) for identification of antibody neutralizing abilities.

METHODSFive BALB/c mice and one New Zealand Rabbit were immunized with recombinant EDIII protein of DENV-1 for the production of hybridomas and hyperimmune sera. Indirect ELISA, immunofluorescence assay (IFA) and Western Blot analyses were applied to identify specificity of antibodies. Comparing to plaque reduction neutralization test (PRNT), the new established DENV-1 specific NS1 antigen capture ELISA was used for detecting the neutralizing abilities of these antibody.

RESULTSFour strains of monoclonal antibodies (mAbs) named 1A1, 1B3, 3D3 and 9D6 and one hyperimmune serum of rabbit were obtained, all of which were approved to have neutralizing abilities to DENV-1 with the PRNT titer of 1:1024, 1:512, 1:256, 1:4096 and 1:4096. MAb 3D3 with the lowest neutralization titer in PRNT had not shown neutralizing ability to DENV-1 in NS1 antigen capture ELISA, while MAbs 1A1, 1B3 and 9D6 and the rabbit hyperimmune serum could protect the C6/36 from being infected by DENV-1 with the neutralization titer of 1:32, 1:32, 1:128 and 1:128 in this assay.

CONCLUSIONNS1 antigen capture ELISA could be used to identify antibody neutralizing abilities to DENV, it was a faster and more convenient way to screen antibodies with high neutralization titer and might also be used as one of the methods to evaluate the effects of vaccines.

The novel paclitaxel-loaded nanopaticle through surface modification with didodecylmethylammonium bromide (DMAB) was prepared and its prevenative against neointimal formation in a rabbit carotid artery injury model was tested. Paclitaxel-loaded nanoparticles were prepared from oil-water emulsions using biodegradable poly (lactic acid-co-glycolic acid) (PLGA). Specific additive for surface conjugation was added after particle formation. To enhance arterial retention using a cationic surfactant, DMAB, was used. The size and distribution, surface morphology and surface charge of the paclitaxel-loaded nanoparticles were then investigated by laser light scattering, scanning electron microscope and zeta potential analyzer. The drug encapsulation efficiency (EE) and in vitro release profile were measured by high-performance liquid chromatography (HPLC). Balloon injured rabbit carotid arteries were treated with single infusion of the paclitaxel-loaded NP suspension and observed for 28 days. The inhibitory effects of vascular smooth muscle cell migration and proliferation were evaluated as end-point. The NPs showed spherical shape with diameter ranging from 200 to 500 nm. The negatively charged PLGA NPs shifted to positive after the DMAB modification. The in vitro drug release profile showed a triphasic release pattern. 28 days later, morphologic analysis revealed that the inhibitory effect of intima proliferation is dose-dependent, and the 30 mg x mL(-1) nanoparticle concentration suspension could completely inhibit proliferation of intima. Paclitaxel-loaded nanoparticles through surface modification with DMAB provide an effective means of inhibiting proliferation response to vascular injury in the rabbit.

OBJECTIVETo investigate the effects of peroxisome proliferator-activated receptor (PPAR) α/γ agonist on atherosclerotic plaque stabilization in diabetic LDL receptor knockout (LDLr-/-) mice.

METHODSFemale 4-week-old LDLr-/- mice fed with high-glucose and high-fat diet for 4 weeks were randomly divided into three groups (n = 15 each): control group (only fed with high-glucose and high-fat diet), diabetic group [induced by high-glucose and high-fat diet combined with a low-dose of streptozotocin (STZ)] without tesaglitazar and with tesaglitazar (20 µg/kg oral treatment). After 6 weeks, the mice were sacrificed, body weight, fasting blood glucose (Glu), total cholesterol (TC), triglyceride (TG) levels were measured. The expression of ICAM-1, VCAM-1, MCP-1 in the brachiocephalic atherosclerotic lesions were determined by Western blot and immunohistochemistry, respectively. Brachiocephalic artery was prepared for morphologic study (HE, oil red O, Sirius red staining) and immunohistochemical analysis (macrophage surface molecule-3, α-smooth muscle actin), respectively.

RESULTSSerum TC [(32.34 ± 3.26) mmol/L vs. (16.17 ± 1.91) mmol/L], TG [(3.57 ± 0.99) mmol/L vs. (2.21 ± 0.11) mmol/L] and Glu [(15.21 ± 4.67) mmol/L vs. (6.89 ± 0.83) mmol/L] levels were significantly higher in diabetic group than in the control group (all P < 0.01). The expression of ICAM-1 (2.31 ± 0.35 vs.1.34 ± 0.21), VCAM-1 (1.65 ± 0.14 vs.0.82 ± 0.26), MCP-1 (2.27 ± 0.16 vs.1.56 ± 0.23) were significantly upregulated in diabetic group compared with control group (all P < 0.01). Brachiocephalic atherosclerotic plaque area [(4.597 ± 1.260)×10(3) µm(2) vs. (0.075 ± 0.030)×10(3) µm(2)], lipid deposition [(47.23 ± 2.64)% vs. (9.67 ± 1.75)%], Mac-3 positive area [(19.15 ± 3.51)% vs. (1.72 ± 0.16)%], α-smooth muscle actin [(5.54 ± 1.17)% vs. (2.13 ± 0.41)%] and collagen content [(4.27 ± 0.74)% vs. (0.43 ± 0.09)%] were all significantly larger/higher in diabetic LDLr-/- mice than in the control group (all P < 0.01). While tesaglitazar treatment significantly reduced serum TC [(30.47 ± 3.18) mmol/L], TG [(3.14 ± 0.71) mmol/L] and Glu [(7.92 ± 1.28) mmol/L] levels (all P < 0.01). Similarly, the expression of ICAM-1 [(1.84 ± 0.22)], VCAM-1 [(1.27 ± 0.11)], MCP-1 [(1.83 ± 0.24)], brachiocephalic atherosclerotic lesion area[(1.283 ± 0.410)×10(3) µm(2)], lipid deposition[(23.52 ± 1.39)%] were also significantly reduced by tesaglitazar (all P < 0.05). Moreover, tesaglitazar increased α-smooth muscle actin [(9.46 ± 1.47)%] and collagen content [(6.32 ± 1.15)%] in diabetic LDLr-/- mice (all P < 0.05). In addition, lipid deposition and Mac-3 positive areas [(10.67 ± 0.88)% vs. (15.83 ± 1.01)%] in the aortic root were also reduced in tesaglitazar treated diabetic LDLr-/- mice (P < 0.01).

CONCLUSIONSTesaglitazar has anti-inflammatory effects in the diabetic LDLr-/- mice. Tesaglitazar could reduce lipid deposition, increase collagen and α-SMA content in the brachiocephalic atherosclerotic lesions, thus, stabilize atherosclerotic plaque in this model.
