[Objective] The aim of this study is to investigate the mechanism and curative effect of cataplasma of Artemisia Argyi by supercritical CO 2 fluid extraction to rat weight, foot swel ing, interleukin-1β, interleukin-17 and tumor necrosis factor-αin the adjuvant arthritis rat models;and afford theoreti-cal evidence for clinical work.[Methods]50 healthy male SD rats were randomly divided into 5 groups:Control group, Model group, Low-dose treatment group, Medium-dose treatment group, High-dose treatment group. Model and al treatment goups took CFA for model ing. After establishing animal models of AA rats, the first group and second group used cataplasm without active drug ingredients. Other groups were given treatment according to dif-ferent drug doses. Assess the joint swel ing degree at different times. Measure the arthritic index and rat weight in two weeks. After 21 days ,detect the cy-tokines level of IL-lβ,IL-17 and TNF-α from the rat's serum and examine the pathological changes of joint observed by HE . [Results]Cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction can significantly reduce rat foot swel ing of the ankle joint pathology ,reduce arthritis score and slow down the weight loss,meanwhile,effectively improve the general daily behavior of rats. The standard of IL-1β,IL-17,TNF-α in serum can be decreased by cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction. The pathological result showed: in the treatment group,the rats synovial hyperplasia the vesselwing reduced, the inflammatory cel infiltration was more decreased than the model group. [Conclusion]The result showed that the cataplasma of Artemisia Argyi by supercritical CO2 fluid extraction had an obvious effect in treating RA. The mechanism was probably that it regulated the immune dis-order of RA.

Objective:To evaluate the predictive value of 3 methods, namely plasma paraquat concentration, severity index of paraquat poisoning (SIPP), and acute physiology and chronic health evaluation (APACHE II) in severity evaluation and prognosis of acute paraquat poisoning. Methods:A total of 73 acute paraquat poisoning patients with oral administration were collected. Paraquat concentration in the plasma and other parameters on admission for SIPP and APACHE II were taken from medical records. According to the clinical outcome in the hospital or 7 days atfer the discharge, discrimination and calibration test were performed to evaluate the prognosis of the 3 methods. Results:Discrimination of the 3 methods was greater than 0.8, and the area under the receiver operator curve for SIPP (0.938) was greater than paraquat concentration in the plasma (0.857) and APACHE II (0.801) with statistical signiifcance (z=2.429, 2.021;P=0.015, 0.043). Difference in plasma paraquat concentration (0.857) and APACHE II (0.801) had no statistical signiifcance (z=0.755, P=0.450). Hosmer-Lemeshow good fit test suggested better calibration value with statistical signiifcance for the 3 methods (P>0.05). Conclusion:hTe 3 methods are valid in the severity evaluation and prognosis of acute paraquat poisoning. SIPP is the most preferred method, followed by paraquat concentration on admission. When there is no facility to measure paraqut concentration, APACHE II can be used as a reference for the death risk in acute paraquat poisoning.

Objective To investigate the expression and clinical signification of tumor M2 pyruvate kinase in pa-tients with CRC, and to try to find a reliable and atraumatic method to predict the progress and pronosis in the CRC. Methods ELISA method was used to determine the serum levels of tM2-PK in 68 patients with CRC,40 pa-tients with colorectal polyps and 40 cases of normal subjects; immunohistochemistry ( IHC ) methods were respec-tively used to detect the expression of tM2-PK in tissues. Results ① The level of serum tM2-PK in patients with CRC was significantly higher than the group of patients with polyps and the normal subjects ( P<0.05 ) . The serum tM2-PK levels was closely correlated to tumor size and Duke stage.②The positive rate of tissue tM2-PK was signif-icantly higher in CRC than in colorectal polyps and normal subjects ( P<0.05 ) . Tissue tM2-PK levels was closely correlated to tumor size,Duke stage and differentiation grade. ③Serum tM2-PK levels was correlated to tissue tM2-PK levels (r=0.357,P=0.003). Conclusion Combined detection of expression of tM2-PK can provide the basis theory for the diagnosis and prognosis evaluation of CRC.

Objective:To discuss the regulation requirements of software based on the analysis of software-related recalls of medical devices. Methods:The data of software-related recalls of medical devices in America were collected and processed, and the type, situation, cause and trend of software-related recalls were analyzed, then the suggestions on the regulation requirements of software were proposed. Results:During the four periods from 1983 to 2011, the percentage of software-related recalls vs medical device recalls in America increased from 6%to 19%, and the year-on-year growth rate of software-related recalls rose by 47%to 164%, significantly higher than medical device recalls in the same period (from 13%to 54%). Especially, the problem of software-related recalls in radiology medical devices was the most serious. Conclusion: The regulatory situation of software is more complicated and severe, so the regulation requirements of software, including software validation, adverse event monitoring and usability design, need to be further strengthened according to the particularity of software.

Objective To investigate the effects of intravenous injection of α-crystallin on retinal ganglion cells (RGC) and some important organs of the Long Evans rats. Methods RGC were retrogradelabeled by fluorogold through bilateral superior colliculus and lateral geniculate body for seven days before optic nerve crush injury. Twenty-three Long Evans rats were used for this study, including three rats of normal control group and 20 rats of experimental group. Twenty rats were randomly divided into saline control group and three α-crystallin injection groups, which received tail vein injection of 1.25 ml isotonic saline and three different concentrations (1 × 10-2 , 1 × 10-1 and 1 g/L) of α-crystallin respectively, once every two days and totally seven times. After two weeks, the labeled RGC were counted, and the pathological changes on liver, kidney, brain, spleen and the lungs were investigated. Results Compared with the normal control group, although the number of RGC markedly decreased after two weeks of optic nerve crush injury in every group, the number of RGC in α-crystallin-treated groups was more than those in the saline control group. There were 2074± 150 RGC per mm2 in normal control group, 85 ± 15 RGC per mm2 in saline control group, 124±26 RGC per mm2 in 1 × 10-2 g/L α-crystallin group, 128± 31 RGC per mm2 in 1 × 10-1 g/L α-crystallin group, 164 ± 20 RGC per mm2 in 1 g/L α-crystallin group (F= 18. 660,P＜0. 01). No congestion, swelling, inflammation and other pathological changes were found in liver,kidney, brain, spleen and lung. Conclusions Intravenous injection of α-crystallin protein has protective effects on RGC after the optic nerve crush injury, and no significant effects on important organs.
