Juvenile idiopathic arthritis(JIA)is the most common rheumatology disease in childhood period with poor prognosis.The biological agents are newly developed drugs with features of clear therapeutic targets and fast effects.But its use in JIA is still limited,so this article focuses on the clinical use experience,timming and sideffects of the biological agents on JIA.

ObjectiveTo observe the efficacy and safety of patient-controlled intravenous analgesia (PCIA) with morphine and fentanyl after cardiac surgery.MethodsSeventy patients operated with cardiac surgery were randomly divided into morphine group (group M) and fentanyl group (group F). The beginning efficacy time of analgesia,efficacy of analgesia,patient's evaluation,heart rate,respiratory rate,mean arterial pressure,and incidence of nausea and vomiting were assessed.ResultsThere were no significant differences in efficacy and patient's evaluation between two groups. In group G,the beginning efficacy time of analgesia was significantly shorter than those in group M (P<0.05),and the times of nausea and vomiting were significant less than those in group M (P<0.05).ConclusionPCIA with fentanyl and morphine for postoperative pain relief after cardiac surgery is efficient and safe. Compared with morphine,the beginning efficacy time of fentanyl is significant shorter,and times of nausea and vomiting are little.

Objective To prepare and characterize the monoclonal antibodies (McAbs) against recombinant adhesion protein 33 (AP33) of Trichomonas vaginalis. Methods The purified recombinant fusion protein AP33 was used as antigen to immunize BALB/c mice. Sp2/0 myeloma cells were fused with the splenocytes from immunized BALB/c mice. After ELISA screening and 4 times of limited dilution, 5 positive hybridoma cell lines were obtained, and the biological properties of the McAbs were identified by Western blotting. Indirect immunofluorescent antibody test (IFAT) was performed and the inhibition effect of McAbs on the cytoadherence of T.richomonas vaginalis to HeLa cell was assayed. Results Western blotting demonstrated that 5 McAbs, designated as 4A2, 4F11, 4F8, 4E7 and 4H11, specifically combined with the recombinant AP33 of T.vaginalis. The McAbs were IgG1 isotypes. Four of them (4F11, 4F8, 4E7 and 4H11) showed parasite recognition by IFAT. Parasite cytoadherence to a monolayer of HeLa cells was inhibited in vitro with a inhibition rate of 50.08%, 65.03%, 50.70% and 49.08% by the 4 McAbs under a concentration of 200, 200, 400 and 200?g/ml, respectively. Conclusions The prepared McAbs against the recombinant AP33 show a protective inhibition on cytoadherence of Trichomonas vaginalis in vitro.

Objective:To study the effects of ~(125)I-(α_v)ASODN on the in vitro invasive ability of heptocellular carcino-ma cell line(HepG2) through PEI-RGD-mediated receptor process. Methods: Intergrin α_v-specific antisense oligonucle-otide was labeled with ~(125)I, and PEI-RGD/~(125)I-(α_v)ASODN complex was prepared by combining ~(125)I-(α_v)ASODN with polyethyleneimine derivative PEI-RGD. PEI-RGD/~(125)I-(α_v)ASODN complex was transferred into HepG2 cells through the receptor-mediated process. The effect of PEI-RGD/~(125)I-(α_v)ASODN complex on the invasive ability of HepG2 cells was examined by Boyden chamber invasive assay. Results: (1) The labeling yield and radiochemical purity of ~(125)I-(α_v) ASODN were(73.78±4.09)% and(96.68±1.38)%, respectively, and the labeled compound had a good stability in vitro after 48 h at 37℃; (2) The ability of HepG2 cells to uptake PEI-RGD/~(125)I-(α_v)ASODN reached its peek ([12.77±0.85] % ) when PEI-RGD/~(125)I-(α_v)ASODN was at 4 μl/2 μg ([12.77±0.85] %), and then gredually decreased thereafter. So the dosage of PEI-RGD/~(125)I-(α_v)ASODN for the following experiment was chosen as 2 μl/1 μg; (3) The invasive capacity of HepG2 cells was significantly reduced in PEI-RGD/~(125)I-(α_v)ASODN group compared with those in other experiment and control groups (P <0.01 ). Conclusion: ~(125)I-(α_v)ASODN mediated by PEI-RGD can effectively inhibit the invasive capacity of HepG2 cells.

Methods According to the target value and operational procedure of international reference material ERM-DA471 ,We have tested 6 dilutions of standard material candidate Cystatin-C on calibrated Hitachi 7180 immunoassay system .Results The results demon-strate good repeatability and commutability ,and have been accepted in calculating the final value for the candidate standard materi-al ,our data has assisted Beijing Institute of Medical Device Testing in passing the criteria and obtaining Cystatin-C national standard material certificate .Conclusion Compared to the data from all participating collaborators ,our results hit right on the target value , and no significant matrix effects have been observed .

Objective To investigate the application of left transthoracic small incisions in combination with tubular gastrectomy for radical esophageal cancer surgery in elderly patients.Methods Clinical data of 83 patients with carcinoma in the middle or lower third of the esophagus aged ≥ 70 years who had undergone radical surgery at our hospital from January 2012 to September 2014 were collected.Patients were divided into two groups:the tubular gastrectomy group (n=38) which had undergone radical surgery through left transthoracic small incisions in combination with tubular gastrectomy and the stomach group (n =45) which had been treated with esophagectomy through conventional left posterolateral incisions and esophageal reconstruction with the remnant stomach.Clinical outcomes were compared between the two groups.Results Compared with the stomach group,operative blood loss [(204.3±75.4) ml vs.(258.4±80.2) ml,t=2.720,P＜0.05],chest drainage on the first and second postoperative day [(201.7±82.6) ml vs.(320.5±78.1) ml,(150.8±83.0) ml vs.(244.6 ± 81.2) ml,t =3.221 and 3.189,respectively,each P＜0.05],pain scores on the third postoperative day [(3.73 ± 1.02) vs.(0.24 ± 1.15),t =2.858,P ＜ 0.05],incidence of arrhythmia (13.2％ vs.33.3％,x2 =4.585,P＜0.05),pulmonary complications (18.4％ vs.46.7％,x2=7.353,P＜0.05) and incidences of gastroesophageal reflux and gastric emptying disorders (23.7％ vs.55.6％,0.0％ vs 11.1％,x2 =8.654 and 4.493,both P＜0.05) were less or lower in the tubular gastrectomy group.The two groups had no significant difference in operation time,length of hospital stay,anastomotic leakage,anastomotic stenosis or 1-year survival rate (each P ＞0.05).Conclusions Radical surgery with small incisions through the left chest combined with tubular gastrectomy shows highly favorable clinical outcomes in elderly patients with middle or lower esophageal cancer,and can significantly reduce surgical trauma,decrease postoperative complications,improve the quality of life,and help patients recover after surgery.
