Objective To analyze the correlation between the early sacroiliitis in ankylosing spondylitis(AS) and clinical and laboratory parameters.Methods 39 patients with AS corresponding to the modified New York criteria for AS(0-Ⅲ)were included.According to pain score(BASDAI),the patients were divided into three groups,that were static group,suspicious active group and active group.The patients were examined by MRI and laboratory including erythrocyte sedimentation rate(ESR) and C-reactive protein(CRP).The severity of activity of sacroiliac joint(SIJ) inflammation was evaluated using spondyloarthritis research consortium of Canada(SPARCC)score,comparative analysis was done among these three groups.Results There was significant differences among these three groups in SPARCC score(P0.05).The spearman correlation coefficient between SPARCC score and BASDAI score was rs=0.503,P0.05.Conclusion In early sacroiliitis of AS,the SPARCC score of SIJ lesions is positively correlated with the severity of BASDAI,but there is no correlation between the SPARCC score and ESR,CRP.

Diabetic macular edema ( DME ) is a major cause of visual impairment in patients with diabetes mellitus, the central retinal thickness ( CRT ) is correlated with the visual impairment and the changes of visual function before and after treatment. Furthermore, CRT is related to the changes of macular microstructure. The subtle changes of retinal microstructure can be qualitative and quantitative analyzed by spectral- domain OCT ( SD -OCT) . In this study, the changes of retinal microstructure in patients with DME are reviewed, what is of great meaning to explore mechanism, observe disease progress, guide clinical treatment and prospect prognosis of DME.

With the increasing frequency of international exchanges and cooperations,students from foreign countries,such as India and Pakistan,have come to our country for their higher degree education.We studied retrospectively and explored the teaching methods of Histology in English,and further provide our thoughts and viewpoints on improving the teaching qualities of foreign students.

Cardiovascular disease is the most important factor that affect the lifetime of uremia patients. Recently, scientists pay closer attention to study the mechanism of cardiac injury in uremia patients. In this article, we will make an overview on mechanism of cardiac injure caused by uremia toxin, secondary hyperparathyroidism, calcium-phosphorus metabolic disorder, rennin-angiotensin-aldosterone system.

Objective To compare the efficacy of mechanical ventilation (MV) with low tidal volume (LTV) plus positive expiratory end pressure (PEEP) and conventioal MV in the treatment of traumatic acute respiratory distress syndrome(ARDS). Methods From Oct 1997 to Oct 2003, 26 cases of traumatic ARDS patients were treated by conventioal MV(group A, n=11) or MV with LTV plus PEEP(group B,n=15), and clinical data of the patients were recorded and compared. Results There were no statistical difference in the PaO 2 of blood gas analysis and hemodynamic indices between the two groups, while the PaCO 2 was higher in group B than that in group A(P

Objective To evaluate the biocompatibility,immunology and physiologic features of encapsulated Newborn Porcine Islets(NPI) in the liver of the recipient dogs with type I diabetes.Methods Type I diabetic dogs were perfused with 400 000-600 000 encapsulated NPI(group A,n = 15)or unencapsulated NPI(group B,n = 15)through the hepatic artery without immunosuppressive treatment.Liver function and CD4/CD8 in the recipients were measured before and after the transplantation.The livers from all NPI recipient dogs were analyzed by histopathology 6 months after transplantation(Tx).Results Insulin dose administrated to group A was reduced gradually within one week after Tx,from 22 u before Tx to 5 u after Tx,exogenous insulin required for group B was decreased from 24 u to 10 u.However,2 to 3 weeks after Tx,the insulin dose given to group B returned to the original level before Tx.In contrast,the amount of insulin administrated to group A was continually reduced to 8 u.Moreover,CD4+ cells in the blood of group B recipients were higher than that before Tx,whereas no significant alteration of CD4+ cells and CD8+ cells in the blood of group A after Tx.All NPI recipient dogs demonstrated a normal function and structure of the liver after Tx.Conclusion Microcapsulated NPI has a good biocompatibility in recipients livers providing prolong-ation of xenograft survival,and correcting the hyperglycemia of diabetic canines.(J Intervent Radiol,2006,15: 607-610)

[Objective]To discuss the clinical outcomes of low-energy tibial plateau fractures treated with arthroscopy-assisted operative management and locked by LCP.[Method]From January 2006 to March 2007,15 patients with tibial plateau fractures(SchatzkerⅠ,Ⅱ)were reduced with arthroscopy-assisted and treated by LCP and bone defects were filled with homogeneous allograft bone.[Result]With follow-up visits for 12～26 months,all cases were healed.According to creiteria of Rasmussen,excellent were in 10 cases,good in 4 cases,fair in 1 case,with the rate of being excellent and good added up to 93%.[Conclusion]LCP fixation is an effective technique for the low-energy tibial plateau fractures treatment with the advantage of less invasion,steadier fixation and lower complication rate.Arthroscopy-assisted operative management can help to reduce reduction loss from intra-articular more precisely to reach a higher union rate.It is also a preferable method for low-energy tibial plateau fracutures treatment(SchatzkerⅠ、Ⅱ).

Objective To observe the clinical efficacy and safety of calcipotriol betamethasone ointment for the treatment of pso‐riasis vulgaris in the stable stage of patient .Methods This was a randomized ,parallel controlled clinical trials ,in which 90 patients with psoriasis vulgaris were randomly divided into experimental group and controlled group .All of them received 4 weeks of thera‐py .We compared the efficacy and safety 1 ,2 ,4 week after treatment by calcipotriol betamethasone ointment .Results About the clinical efficacy ,according to the decrease in percentage of psoriasis area and severity index (PASI) were:23 patients in the experi‐mental group were effective(efficacy rate is 76 .67% ) ,14 patients in control group Ⅰ was effective(efficacy rate is 46 .67% ) ,15 pa‐tients in control group Ⅱ was effective(efficacy rate is 50% ) .The differention between experimental group and the two control groups was significant(P< 0 .05 ,P< 0 .01) .After 1 ,2 ,4 weeks of therapy ,the decrease in percentage of PASI of experimental group is higher than that in the control groups .The scores of the observed erythema ,infiltration ,scale were decreased ,and the total scores of PASI are also decreased 4 weeks after therapy .The decrease score of experimental group is higher than that of control group Ⅰ(P<0 .01) and control group Ⅱ(P<0 .01) .The side effects of the experimental group are mild such as itching ,folliculi‐tis ,erythema ,and the laboratory examinations had no abnormal changes .Conclusion Calcipotriol betamethasone ointment was more effective to treat the stable stage psoriasis vulgaris patients compared with single use of halometasone or calcipotriol .It takes effect quickly ,and could be more feasible and safe .
