Objective To evaluate the efficacy and safety of infliximab and traditional disease modifying antirheumatic drugs (DMARDs) in the treatment of ankylosing spondylitis (AS). Methods Sixty patients with definite AS were treated with infliximab 5 mg/kg infusion at 0, 2, 6, 12 weeks and were followed up for 12 weeks. The primary endpoint was proportion of ASAS 20 responders at week 12. The secondary endpoints were the proportion of ASAS 50, the change from baseline in Bath AS functional index (BASFI).The improvement of signs and symptoms of AS and physical function were evaluated. The statistical treatments were used t-test andA2 test. Results The proportion of ASAS 20 responders at 2, 6, 12 week was 70%, 83% and 93% respectively. The proportion of ASAS50 responders at patients at 2, 6, 12 week was 13%, 37% and 57% respectively. Results for other secondary efficacy endpoints showed that infliximab could provide substantial benefits to patients with AS by reducing clinical signs and symptoms and improving range of motion, physical function and quality of life. Ten percent of the subjects reported treatment- related adverse events. The most frequently occurred were upper respiratory tract infection, followed by gastrointestinal adverse events and infusion reaction. Most treatment-related adverse events were mild to moderate in severity and disappeared after drug withdrawal. Conclusion Infliximab has been demonstrated to be effective and is well tolerated in the treatment of AS.

Objective To detect the pre- and post-treatment levels of serum interleukin (IL-20) in asthmatic patients during the acute exacerbation period and to investigate the role of IL-20 in the pathogenesis of bronchial asthma and relative clinical significance. Methods Forty-five cases of mild to moderate asthma outpatients in the First Affiliated Hospital of Guangxi Medical University from May 2013 to October 2013 were chosen as the asthma group and 32 healthy people who underwent routine physical examination as the control group. All the patients were treated with inhalation salmeterol and fluticasone 50/250 μg/μg (sucking twice a day) together with ventolin if necessary , and even with theophylline sustained-release tablets as the additional treatment in moderate asthma group for 1 week. The serum levels of IL-20 as well as immunoglobulin E (IgE) were detected by ELISA in the asthma group before and after treatment as well as in the control group. Other data including ECP , the number of eosinophil ceils (EOS) and the pulmonary function (FEV1%) were detected as well. The differences of IL-20 levels between the asthma group before and after treatment and the control group were analyzed and the correlation between IL-20 and Ig E, EOS, ECP and FEV1% were analyzed. Results Compared with the healthy control group [(13.58 ± 6.17)pg/L], the levels of IL-20 in the mild and moderate asthma pretreatment group were significantly increased [(23.43 ± 13.60)pg/L and (33.78 ± 22.69)pg/L]. Compared with the mild asthma group, the levels of IL-20 in the moderate asthma pretreatment group were significantly higher. After treatment , the levels of IL-20 [(15.73 ± 8.27)pg/L and (19.64 ± 11.69)pg/L] were decreased respectively in the asthmatic patients. The Pearson correlative analysis showed that there were positive correlations between the levels of 1L-20 and IgE , EOS and ECP respectively and there were negative correlations between IL-20 levels and FEV1%. Conclusion IL-20 may be involved in the pathogenesis of asthma.

BACKGROUNDHepatic alveolar echinococcosis (AE) is a parasitic disease in humans and caused by the Echinococcus multilocularis (Em). Orthotopic liver transplantation (OLT) may be the only effective treatment for end-stage hepatic AE. However, in some AE patients, extrahepatic Em can not be completely eliminated after OLT. We aimed to study whether the immunological changes caused by Em evasion may influence the rejective response.
METHODSRat modles of AE were established by injecting the Em suspension into abdomen of Brown Norway (BN) rats. Three months later, in the experimental group, the liver was transplanted from Lewis (LEW) rats to Em-infected BN rats. In the control group, transplantation was from LEW rats to healthy BN rats. Liver tissue and peripheral blood (PB) samples were collected on days 1, 3, 5, and 7 after OLT. Liver tissue was analyzed after hematoxylin and eosin (H&E) staining; numbers of CD4, CD8, and CD28 on peripheral blood cells were detected by flow cytometry; and expression of the chemokine fractalkine (Fkn) was detected by reverse transcription PCR (RT-PCR). Interleukin-10 (IL-10) was measured in the serum by enzyme-linked immunosorbent assay (ELISA). In every group, eight BN rats were retained for observing survival time.
RESULTSThe survival times of recipients in the experimental group were prolonged compared with those in the control group. The rejective response occurred later and was milder in the experimental group. percentage of CD4, CD8, CD28 T-cells and Fkn mRNA expression were lower in the experimental group. While the serum IL-10 levels were higher in the experimental group than those in the control group.
CONCLUSIONSAcute rejective response after OLT was attenuated in the rats with Em infection, and the recipients` survival time was prolonged. Em may play a role in this process by elevating IL-10 secretion, decreasing the effector T cells, inhibiting the expression of Fkn, which lead to reduce the inflammatory cells infiltration into the liver.

To evaluate the effects of resuscitation with normal saline and sodium potassium magnesium calcium and glucose injection on renal structure and function in septic rats. Rat model of sepsis was established by ligation and perforation of cecum. Male SD rats were divided into four groups: sham operation group, sepsis group, saline resuscitation group, sodium potassium magnesium calcium and glucose injection resuscitation group. Blood gas analysis was performed at the end of resuscitation. The rats were sacrificed 72 hours after resuscitation. Blood samples were taken to measure the plasma levels of blood urea nitrogen (BUN), creatinine, interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factorα (TNFα). Caspase-3 expression was detected by immunohistochemistry in kidney sections. The degree of renal injury was evaluated by regular HE staining and electron microscope. Compared with normal saline resuscitation, sodium potassium calcium magnesium glucose injection resuscitation could decrease the levels of BUN, serum creatinine, IL-1β, IL-6 and TNFα ( P<0.05) , reduce the expression of caspase-3 ( P<0.05) , and improve the renal injury score ( P<0.05) . Sodium potassium calcium magnesium glucose injection resuscitation can significantly improve the renal function of sepsis rats with less pathological damage of the kidney.

ObjectiveXenotransplantation is an effective way to address the shortage of human organ donors, but it faces serious immune rejection reactions, including hyperacute rejection caused by blood type differences. Establishing a stable, convenient, and reliable method for pig blood type identification can quickly screen suitable donor pigs for xenograft research.MethodsBanna miniature inbred pigs, Diannan small eared pigs, and Bama Xiang pigs were selected as the research objects. DNA was extracted from the blood, oral buccal mucosa, and fetal fibroblasts of the three strains of pigs using DNA extraction kits. The target fragment of the ABO homologous gene EAA intron 7 in pigs was amplified using PCR method. Blood agglutination reaction was used to detect hemolysis in pig anterior vena cava whole blood after adding anti A and B antibodies. Immunohistochemical method was used to detect the expression level of A antigen in pig heart, liver, spleen, lung, and kidney tissues. Immunofluorescence method was used to detect the expression level of A antigen in pig oral mucosa. By comparing the results of different methods for determining pig blood types, the stability and reliability of the PCR method were verified, and a convenient PCR based pigblood type identification method was established.Results Firstly, the blood PCR results of 69 inbred strains of Banna miniature pigs, 7 Diannan small eared pigs, and 34 Bama Xiang pigs showed 20 AO blood types, 66 AA blood types, and 24 O blood types. The PCR results of fetal fibroblasts from 47 Diannan small eared pigs showed that all 47 fetuses were O blood type. Among them, the oral mucosal PCR results of 8 gene edited cloned pigs were consistent with those of donor fetal fibroblasts, all of which were O blood type. The oral mucosal PCR results of 8 wild-type pigs (2 inbred lines of Banna miniature pigs, 4 Diannan small eared pigs, and 2 Bama Xiang pigs) were consistent with the blood PCR identification results. Then, 11 inbred lines of Banna miniature pigs, 4 Diannan small eared pigs, and 2 Bama Xiang pigs were randomly selected for blood agglutination reaction validation, and the results were consistent with the PCR identification results of both blood samples and oral mucosa samples. Moreover, immuno-histochemical analysis was performed on the heart, liver, lung, kidney, and spleen tissues of one Banna miniature pig inbred line and two Bama Xiang pigs, and the results were consistent with blood PCR identification and blood agglutination reaction results. Finally, oral mucosal samples were collected from 2 inbred strains of Banna miniature pigs and 1 Bama Xiang pig for immunofluorescence detection, and the results were consistent with the blood PCR identification results.ConclusionBy collecting fetal cells and oral mucosal samples from live pigs for PCR detection, the blood type of pigs can be accurately and efficiently identified, providing a convenient method for blood type screening of xenograft donor pigs.
