Objective To investigate the roles of serum visfatin and VE-cadherin in the pathogenesis of psoriasis vulgaris and their clinical significance. Methods Enzyme-linked immunosorbent assay (ELISA) was used to detect the serum levels of visfatin and VE-cadherin in 78 patients with psoriasis vulgaris before and after treatment and in 30 normal human controls. The relationship between the two parameters and disease activity was evaluated. Results The serum levels of visfatin and VE-cadherin were significantly higher in untreated patients with psoriasis than in the normal controls (I = 10.53, 10.16, both P< 0.01), and in patients with active psoriasis than in those with stable psoriasis (t = 12.47, 13.11, both P< 0.01). The treatment caused a marked decrease in the serum levels of visfatin and VE-cadherin in patients. The serum level of visfatin was positively associated with the level of VE-cadherin and PASI scores (r = 0.58, 0.64, P < 0.01) in patients with psoriasis. Conclusion Visfatin and VE-cadherin may be used as parameters for evaluating disease activity of psoriasis vulgaris.

Objective Inflammatory response is an important part in pathological change of traumatic arthritis(TA).Studies show that hydrogen has antioxidate and anti-inflammatory properties, however, there are few reports on treating TA with it.So this research aimed to investigate curative effects of curing traumatic arthritis in rabbits with intraperitoneal injection of saturated hydrogen saline solution . Methods A total of 26 New Zealand white rabbits were divided into three groups:normal control group (n=6), model experimental group (n=10), and model control group (n=10).Rabbits in model experimental group were intraperitoneally injected with 8 ml /kg saturated hy-drogen saline, once every three day;equivalent saline was injected in rabbits of model control group;while no treatment was done on normal control group.The treatment lasted for 6 weeks.Before and after the treatment, the serum and joint fluid of the rabbits in the three groups were respectively taken to determine the content of nitric oxide (NO) and hyaluronic acid (HA), which was used to evaluate therapeutic effect in combination with the behavioral performance of the rabbits . Results Significant improvement in behavior was found in model ex-perimental group after the treatment (P<0.05).No statistical differences were found in knee swelling scores of the three groupsbefore the treatment(P>0.05), but model experimental group was superior to model control group in knee swelling scores after the treatment (P<0.05).The contents of NO both in serum ([79.58 ±13.46] vs [76.23 ±12.15]) and joint fluid ([89.45 ±14.98] vs [80.36 ±12.78]) in two model groups increased before the treatment, which was of statistical difference (P<0.05), but the NO content decreased dramatically in model experimental group after the treatment ([436.82 ±60.91] vs [340.21 ±40.57],P<0.05), and no obvious changes were observed in model control group (P>0.05).The content of serum HA in model experimental group declined dramatically (P<0.05) and the joint fluid increased after the treatment ([1.72 ±0.37] vs [2.47 ±0.62],P<0.05), while no significant changes were found in model control group before and after the treatment. Conclusion The intraperitoneal injec-tion of saturated hydrogen saline may be effective in the treatment of trau-matic arthritis.

Objective To evaluate the efficacy and safety of sorafenib in combination with interferon-alpha(IFN-α)as the first-line treatment in patients with advanced renal cell carcinoma.Methods Since Dec 2007 to Jun 2008,137 legal patients with advanced renal cell carcinoma (RCC)were enrolled in the trail from 22 hospitals in China.All the patients continuously received the treatment of sorafenib plus IFN-α untill disease progressed or patients were unable to tolerate.The primary end points were objective response,disease control rate and adverse effects rate.Results This interim analysis was based on the data collected from the study initiation date to 2009/3/20.The overall response rate(ORR),including complete response (CR) and partial response(PR),was 32.8%(45/137).The median follow-up time was 11.9 months,only 25 patients progressed at the cut off time.The most common adverse events were hand-foot skin reaction(48.2%),alopecia(23.4%),rash (20.4%),diarrhea(19.7 0A),fever(16.8%),lassitude(10.2%),etc.The incidence of 3 or 4 grade hand-foot skin reaction was 8.8%.Conclusions Sorafenib in combination with IFN-α as the firstline treatment in patient with advanced RCC could be effective and safe.

Objective To study the reliability, validity, sensitivity, specificity and predictive value of the Standardized Swallowing Assessment (SSA) in assessing swallowing function. Methods Sixty-seven stroke patients with dysphagia participated in the study. They were assessed twice with the SSA within 3 days. In addition, the patients' swallowing was also assessed using videofluoroscopy. Results There was high correlation in all items of the SSA between the two separate assessment sessions. The intraclass correlation coefficient was 0.85 for intrarater re- liability and 0.82 for interrater reliability. The SSA and videoflouroscopy results were highly correlated in terms of their total scores (r = -0.86,P≤0.01). Using the videoflouroscopy result as the standard, the sensitivity and spe- cificity of the SSA were 77.8% and 68.1% , respectively. At the same time, the positive and negative predictive val- ues were 48.3% and 88.9% , respectively. Conclusions The SSA has satisfactory reliability and validity, and higher sensitivity and specificity than videoflouroscopy. It is recommended for assessing swallowing with stroke pa- tients.
