Objective To study the prediction value of C-reactive protein (CRP) level to ankylosing spondylitis disease activity score (ASDAS),the most widely used activity score in ankylosing spondylitis (AS).Methods A total of 386 patients with AS were enrolled and divided into 2 groups by CRP≥3.5 mg/L (n =266) and CRP ＜ 3.5 mg/L(n =120).ASDAS-CRP was evaluated in patients with CRP below the normal range (3.5 mg/L) in different subgroups.Three methods were used to test the consistency between ASDAS-CRP and ASDAS-erythrocyte sedimentation rate (ESR).Results The ASDAS-CRP showed a good correlation with the ASDAS-ESR when CRP level was ≥ 3.5 mg/L (r =0.899,P =0.000).In the group of CRP ＜ 3.5 mg/L,ASDAS-ESR showed better consistency with ASDAS-CRP when CRP level was below 1.5 mg/L(intra-class correlation coefficient 0.902;kappa coefficient 0.70).By the evaluation of variant gradient matrix,CRP 1.5 mg/L coincided with disease activity states.Conclusion There is good consistency between ASDAS-CRP and ASDAS-ESR.When CRP level is below the normal range,1.5 mg/L could be a cut-off value to calculate the optimal ASDAS-CRP score.

Objective To analyze antimalarial assosiated retinopathy detected by different methods with of modern ocular fundus examination, and explore screening strategy and the diagnosis of hydroxych-loroquine assosiatedretinopathy according to clinical experience and international guidelines. Methods Full fundus examination was performed in two patients with antimalarial retinopathy. The related literature were reviewed. Results Two patients had bull's eyes maculopathy and abnormal visual fields. Conclusion Clin-icians' alertness to hydroxychloroquine related retinopathy may improve early diagnosis of hydroxychloroquine toxicity. New objective tests are more sensitive than visual fields examination. Visible bull's-eye maculopathy is a late change, and the goal of screening is to recognize toxicity at early stage.

Objective To explore the the role of fraction exhaled nitric oxide(FeNO) in airway inflammation of Mycoplasma pneumoniae pneumonia(MPP).Methods Inpatients with low respiratory tract infection were enrolled from August to November in 2012,69 patients had MPP and 33 had no MPP(non-MPP).Patients with MPP were further grouped into a bronchopneumonia group and the lobar pneumonia group.Fifty-four inguinal hernia patients without respiratory tract infection during the last 2 weeks were enrolled as a control group.FeNO was measured by nitric oxide analyzer.Eosinophile level was detected by blood cells analysator.Results The level of FeNO in patients with MPP [(6.28 ±3.00) ppb] was lower than that of patients of non-MPP [(10.85 ± 2.86) ppb] and the control group [(9.74 ± 3.10) ppb] (t =7.30,6.26,respectively,all P ＜ 0.000 1) ; the level of FeNO between the bronchopneumonia group [(5.78 ± 3.06) ppb] and the lobar pneumonia group [(6.48 ± 2.98) ppb] with infection of Mycoplasma pneumoniae (MP) had no statistical significance(t =0.88,P ＞0.05).The proportion of blood eosinophile in patients with MPP [(0.60 ±0.51) ％] was lower than that of non-MPP group [(1.15 ± 0.76) ％] (t =4.14,P ＜ 0.000 1) ; the proportion of blood eosinophile between bronchopneumonia group [(0.61 ± 0.57) ％] and lobar pneumonia group [(0.60 ± 0.55) ％] with infection of MP had no discrepance (t =-0.05,P ＞0.05).Conclusions MP infection decreases production of FeNO.The possible mechanism for this phenomenon is that the cilia loss and hyperimmune response to MP may affect the production of FeNO.The airway inflammation of mycoplasma pneumonia is associated with cilia loss and hyperimmune response.

Objective To assess the surgical treatment of iatrogenic biliary strictures. Methods The clinical data of 235 patients with iatrogenic biliary injuries and strictures who had been admitted to our hospital from January 1989 to December 2006 were reviewed retrospectively. Cholangio-jejunal Roux-en-Y anastomosis (n=182), surgical repair with pediele flap of autogenous tissues (n=34), end-to-end choledocho-choledo-chostomy (n= 12), common bile duct incision and figuration +T-tube drainage ( n =6) and liver transplanta-tion ( n = 1 ) were applied to the patients. Results A total of 189 patients were followed up for 1 to 10 years. The total excellent and good rate was 94.7% (179/189). The recurrence rate of the biliary stricture was 5.3% (10/189), and the main cause of which were biliary cirrhosis, selerosing cholangitis and calculus. One patient with severe biliary cirrhosis and portal hypertension died of liver failure postoperatively. Conclusions The cholangio-jejunal Roux-en-Y anastomosis is a reliable and effective method. Surgical repair of the bile duet with pedicle flap of autogenous tissues could preserve the function of the sphincter of Oddi, but the long-term effect needs further investigation. Biliary stent is not usually necessary to install. Liver transplantation is efficient for the patients with end stage of biliary diseases caused by biliary stricture.

Objective:To study the influence of protein transduction domain (PTD)-oligomerization domain (OD)-HA fusion proteins on apoptosis of bcr/abl-positive cell lines. Methods:bcr/abl-positive cells were treated with PTD-OD-HA protein. The apoptoses of the cells were detected by flow cytometry (FCM), DNA ladder and transmission electron microscopy (TEM), and the levels of apoptosis-related genes bax and bcl-2 were detected by RT-PCR and Western blotting. Results:FCM examination demonstrated that PTD-OD-HA protein induced the apoptosis of bcr/abl-positive cells; DNA ladder showed that the classic DNA ladders appeared in BaF3-P210 and K562 cells after 48 h treatment with PTD-OD-HA proteins; the apoptoses of BaF3-P210 cells were observed by TEM; the levels of bax in mRNA and protein increased in BaF3-P210 and K562 cells, and bcl-2 decreased. Conclusion:PTD-OD-HA proteins specifically induced the apoptosis of bcr/abl positive cells.

BACKGROUND:We built Sprague-Dawley rat models with mild, moderate, and severe spinal cord injuries to accord with the spinal cord injury types for basic empirical study, and consequently to further understand the microenvironmental change in Sprague-Dawley rats with spinal cord injury, and to provide help for clinical treatment. OBJECTIVE:To observe the changes in nerve function, pathological manifestation and motor sensory evoked potential in Alen’s models and Sprague-Dawley rats with complete spinal cord transection at different time points after spinal cord injury by simulating the microenviroment in Sprague-Dawley rats. METHODS: A total of 125 healthy adult female Sprague-Dawley rats were selected and randomly divided into group sham operation group, 100 gcf hit potential group (20 g×5 cm), 200 gcf hit potential (20 g×10 cm), 300 gcf hit potential group (20 g×15 cm), and spinal cord complete transection group with 25 rats in each group. At 1, 5, 7, 14 and 28 days after model establishment, the degree of spinal cord injury was identified by the BBB scores of motion function, motor evoked potential, and pathological section. RESULTS AND CONCLUSION:(1) Totaly 24 Sprague-Dawley rats died in the experiment. The death rate and the rate of complications were highest in the spinal cord complete transection group. The BBB score of each group was decreased. The BBB scores in every group increased as time went on. There were significant differences between each surgery group and the sham operation group at corresponding time points (P < 0.05). No significant difference was found between the 300 gcf hit potential group and the spinal cord complete transection group at corresponding time points (P > 0.05). (2) In each surgery group, the infiltration of inflammatory cels and obvious sweling of neurons were visible at 1 day after injury. Neural cels reduced with time prolonged. At 28 days after injury, a large number of astrocytes proliferated, scar and spinal cord cavity formed. Above symptoms were worse in the 300 gcf hit potential group and spinal cord complete transection group than in the 100 gcf and 200 gcf hit potential groups. (3) Significant differences in amplitude and latency were detectable between each surgery group and the sham operation group (P < 0.05). No significant difference in amplitude and latency was detected between the 300 gcf hit potential group and the spinal cord complete transection group at corresponding time points (P > 0.05). Results confirmed that hit potential of 20 g×5 cm, 20 g×10 cm and 20 g×15 cm can simulate the microenvironment of Sprague-Dawley rats with mild, moderate and severe spinal cord injury. The rate of complication was lower in modified Alen’s model of different hit potentials than in models of spinal cord complete transection, and was more accorded with basic research.

OBJECTIVE To explore the protective effect of polysaccharides from Salvia Chinensis Benth. (PSSC) on lipopolysaccharide (LPS) and D- galactosamine (GalN)- provoked mouse acute liver failure (ALF) and the possible molecular mechanism. METHODS Kunming mice were randomly divided into four groups: normal control, model, model+PSSC 30 and 100 mg·kg- 1 groups. PSCC was given once a day and for a week. To establish an ALF model, mice of model and PSSC groups were ip injected with LPS 10 μg·kg-1 and GalN 700 mg·kg-1 at the end of PSSC treatment. The microscopic structure of the liver was detected by HE staining. Serum and hepatic biochemical parameters of glutamic-oxalacetic transaminase (GOT), glutamic- pyruvic transaminase (GPT), catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), and glutathione (GSH) were detected by colorimetric methods. The relative content of hepatic reactive oxygen species (ROS) was measured by DCFH-DA fluorescent probes. Levels of cytokines tumor necrosis factor-α (TNF-α), interleukin 1β(IL-1β) and IL- 6 in the serum and liver were detected by ELISA. Activity of caspase 3 in liver homogenates was detected by aspase 3 activity assay kit. RESULTS Compared with normal control group, in the liver of model group, hepatocytes were arrayed in disorder, cytoplasm of hepatocytes shrank, and boundaries between cells were fuzzy, the infiltration of a large number of inflammatory cells and tissue hemorrhage could be detected, pathological scores were elevated significantly (P<0.01), levels of MDA and ROS in the liver of ALF model mice were elevated to 2.2 and 4.3 times that of the normal control, respectively (P<0.01), the level of GSH decreased to 51% (P<0.01), and the activities of SOD, CAT and GSH- Px declined to 74%, 36% and 42%, respectively (P<0.01). Levels of TNF- α, IL- 1β and IL- 6 in the serum and liver of model group were increased (P<0.01), and caspase 3 activity was increased to 5.3 times that of the normal control (P<0.01). Compared with the model group, the number of surviving mice in PSSC groups increased, liver pathological scores declined (P<0.01), levels of MDA and ROS increased (P<0.01), levels of GSH, TNF-α, IL-1β and IL-6 in the liver and serum declined (P<0.01), and caspase 3 activity decreased (P<0.01). CONCLUSION PSSC is able to alleviate LPS and GalN-induced ALF in mice. Inhibition of hepatic oxidative stress, inflammatory response, and cell apoptosis is possibly implicated in the protective effect of PSSC.
