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 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.

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 explore the mechanism of acupuncture in regulating cognitive deficits in insomnia rats by observing the effect of acupuncture on microglia in thalamic reticular nucleus (TRN). Methods: Thirty rats were randomly divided into a control group, a model group and an acupuncture group, with 10 rats in each group. The insomnia model was established by intraperitoneal injection of para-chlorophenylalanine (PCPA) once a day for 2 d. Rats in the control group were intraperitoneally injected with the same amount of normal saline. Rats in the acupuncture group received acupuncture at Neiguan (PC 6) and Zusanli (ST 36) for 5 consecutive days. The CLOCKLAB 2 data acquisition system was used to dynamically observe the sleep of the rats throughout the experiment. The cognition of rats was evaluated by event-related potentials (ERPs). After intervention, brain tissue was extracted. Immunofluorescence was used to test the fluorescence expression in TRN region. The concentrations of interleukin (IL)-1β and tumor necrosis factor (TNF)-α were detected by enzyme-linked immunosorbent assay. Results: After intraperitoneal injection of PCPA suspension, the spontaneous activity in light period of rats in the model group and acupuncture group increased significantly compared with the control group (both P<0.01). After acupuncture treatment, the rats in the acupuncture group had much less spontaneous activity during the light period than those in the model group (P<0.01), and the results indicated that acupuncture could effectively improve the sleep quality of insomnia rats. Compared with the control group, rats in the model group showed that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α increased significantly (all P<0.05), and the P3 amplitude decreased significantly (P<0.01). Compared with the model group, rats in the acupuncture group presented that the P3 latency, the average optical density of microglia, and the concentrations of IL-1β and TNF-α were significantly decreased (all P<0.05), and the amplitude of P3 was significantly increased (P<0.05). Conclusion: Acupuncture possesses an ability to improve the cognitive state in insomnia rats. The mechanism may be related to inhibiting the microglial activation, diminishing the levels of pro-inflammatory mediators like IL-1β and TNF-α, and promoting the recovery of central nervous system function.
