Objective To investigate the effects and partial mechanism of prednisone and TACI-Ig combination on MRL/Mpslac-lpr ( MRL/lpr) mice. Methods MRL/lpr mice were randomly divided into 6 groups, which includ-ed model group, prednisone (2. 5, 5. 0 mg/kg) group, TACI-Ig (15. 0 mg/kg) group, prednisone and TACI-Ig combination [(2. 5+7. 5) mg/kg, (2. 5+15. 0) mg/kg] group. BALB/c mice were set as normal group. Pred-nisone was given intragastrically everyday and TACI-Ig was given subcutaneously every two days for 13 weeks. In the meantime, the normal and model group were treated with an equal volume of normal saline. The general sign and proteinuria level were observed in the treatment period. The sections of spleen and kidney tissues for pathologi-cal analysis were stained with HE. Serum levels of auto-antibodies and BAFF were detected by ELISA kit. The per-centage of plasma cells and CD138 expression in the spleen were detected by flow cytometry analysis and immuno-histochemistry, respectively. Results The skin damage and the proteinuria level were improved and decreased by prednisone and TACI-Ig combination treatment. The spleen and kidney pathology were also improved including re-ducing germinal center formation and alleviating the glomerular fibrosis, mesangial cell hyperplasia and inflammato-ry cell infiltration, respectively. What was more, the percentage of splenic plasma cells ( CD19 -CD138 +) was re-duced significantly, which maybe resulted in the decrease in ANA. However the high level of anti-dsDNA antibody was not influenced by the combination treatment. The serum level of BAFF was also reduced by the combination treatment. Conclusion Prednisone and TACI-Ig combination treatment has a beneficial effect on murine SLE, which may be associated with the inhibition of plasma cell differentiation and the secretion of auto-antibody.

This study is to investigate the protective effect of mangiferin on NF-kappaB (P65) and IkappaBalpha expression in peripheral blood mononuclear cell (PBMC) in rats with cigarette smoke induced chronic bronchitis. The rat model with chronic bronchitis was established by cigarette smoke. Real-time fluorescence RT-PCR was executed for evaluating the NF-kappaB (P65) and IKkappaBalpha gene expression in mononuclear cell, and flow cytometry for their protein expression. The serum hs-CRP (high-sensitivity C-reactive proteins) and TNF-alpha (tumor necrosis factor-alpha) were detected by enzyme-linked immunosorbent assay. The histopathological score was obtained from lung tissue HE staining slides of lung tissue. The results showed that mangiferin could markedly suppress the NF-kappaB (P65) mRNA and protein expression in mononuclear cell, while promote the IkappaBalpha mRNA and protein expression. Furthermore, mangiferin could lower serum hs-CRP and TNF-alpha level, and reduce the chronic inflammatory damage of bronchiole. These results suggested that mangiferin could notably ameliorate chronic bronchiole inflammation induced by cigarette smoke, and this protective effect might be linked to the regulation of NF-kappaB (P65) and IkappaBalpha expression in mononuclear cell.

Mango leaves have been widely used in the clinical practice for thousands of years in traditional Chinese medicine.Mangiferin,an effective constituent in the mango leaves,has multiple pharmacological actions involved in some basic pathological processes,such as inflammation,oxidative injury,tumor growth,micro-organism infections,metabolic regulations,and immunological regulations.The pharmacological effects of mangiferin from some published data are reviewed in this article.

OBJECTIVEThe clinical results of restoring defective teeth with two types of glass fiber prothetic systems is investigated to acquire clinical experience for further application of glass fiber posts with independent intellectual property rights.

METHODSA total of 120 out-patients with restored defective teeth were selected from the Department of Stomatology, Beijing Xuanwu Hospital of Traditional Chinese Medicine and Peking University School and Hospital of Stomatology and randomly divided into two groups. OUYA FIBER posts and Tenax Fiber White posts were used to restore defective teeth in the experimental group and the control group, respectively. Clinical evaluation was conducted one week and three months post-restoration.

RESULTSBoth clinical satisfactory rates of OUYA FIBER posts and Tenax Fiber White posts were higher than 98% one week post-restoration and higher than 96% three months post-restoration. No significant differences were observed between the clinical results of restoring defective teeth with the two types of fiber posts. Throughout the healing process, no root canal fracture or marginal staining were observed.

CONCLUSIONOUYA FIBER post and Tenax Fiber White post showed similar clinical outcomes during the period of observation in this study. However, the long-term effects should be observed in future studies.

Objective To investigate imaging parameters on low field MRCP and to optimize the quality of images.Methods MRCP in 77 cases were performed using Airis-Ⅱcomfort open 0.3T low field MR imaging system made by HITACHI company.3D-FSE combined with 2D single-shot breath-hold FSE sequences were used.The 3%～5% compound solution of Gd-DTPA was taken to restrain the hige signals from remaining liquid in stomach.Results MRCP examination was succeeded in all 77 cases and the images in all cases but 2 were fine for diagnosis.The total diagnostic accuracy was 79.2%.The accuracy of MRCP in the detection of the degree and location of pancreaticobiliary duct obstruction was 100%. Conclusion The distinct MRCP images can be obtained with low field MR system using combination of several scanning techniques and proper scanning parameters,and also patients have to prepare fully.

Objective To evaluate the diagnostic value of the low field MRCP in obstructive jaundice by comparing its result with that of US and CT. Methods 55 cases of obstruction jaundice patients proved by clinical diagnosis were studied and compared the collected original diagnosis results by low filde MRCP with US and CT.Results Of 55 cases of obstructive jaundice, 30 were cholelithiasis ,21 were tumors and 4 belonged to the other type. The accuracy of MRCP for defining the site of obstruction was 100%. The accuracy for identifying the cause of obstruction was 81.8%.Conclusion The low filde MRCP can accurately define the obstructive site in biliary obstructive disease .When used together with 2D single-shot breath-hold MRCP , T 2WI, T 1WI and 3D-FSE MRCP shows high accuracy and sensitivity in diagnosing obstructive jaundice.

Objective To study the urodynamic change of young and middle-aged patients with chronic prostatitis,and provide reference for clinical diagnosis and treatment.Methods Seventy young and middle-aged patients with chronic prostatitis were selected,the bladder capacity,bladder stability,bladder compliance,detrusor pressure and bladder pressure volume curve etc were measured.Results Unstable of detrusor contraction of 20 cases (28.6％,20/70),bladder sensitivity of 35 cases (50.0％,35/70),detrusor underactivity of 46 cases (65.7％,46/70).In 70 young and middle-aged patients with chronic prostatitis,the maximum bladder capacity was 100-497 (380 ± 80) ml,the detrusor pressure at maximum flow rate was 11.2-112.2 (38.4 ± 3.9) cm H2O (1 cm H2O =0.098 kPa),the drop of maximum flow rate was (10.53 ± 1.92) ml/s.Conclusions Through the urodynamic examination,the lower urinary tract obstruction syndrome can be found in young and middle-aged patients with chronic prostatitis,especially who have no significantly improvement after drug therapy.Now,the urodynamic examination for the lower urinary tract obstruction is a credible way to diagnosis,which plays an important role in diagnosis of chronic prostatitis and is useful for clinical practice.

The overall concept is the core theory of traditional Chinese medicine ( TCM ) diagnosis and treat-ment system. During the process of building TCM effect evaluation on coronary heart disease (CHD), with the defined connotation and extension of heart diseases , except the consideration on its clinical symptoms , TCM four diagnosis and various current modern cardiovascular disease diagnostic methods should be organically com-bined according to the original macro basis . The micro quantitative evaluation is given on therapeutic effect of disease treatment in order to construct the complete TCM effect evaluation system.
