Objective To explore the effect of vasoactive intestinal peptide ( VIP) on the prevention and treatment of experimental autoimmune encephalomyelitis(EAE) rats by regulating the levels of IFN-γand IL-17A in brain tissue. Methods Sixty healthy female Wistar rats were randomly divided into 4 groups:normal control group, EAE control group, VIP low-dose group and VIP high-dose group.Myelin basic protein ( MBP)+complete Freurd′s adjuvant ( CFA) was used to establish an EAE model.The low and high-dose VIP groups were intraperitoneally injected with VIP 4 nmol/kg(0.2 ml) and 16 nmol/kg (0.8 ml) respectively every other day,while normal control group and EAE group with 0.8 ml saline for ten consecutive days.The incubation period, progression and peak of neurological dysfunction score ( NDS) changes of rats were recorded.The pathological changes, the GFAP+astrocyte activation in the brain at the morbidity peak of rats and the cytokine levels of IFN-γand IL-17A in brain tissue were observed.Results The incubation period was extended, the progression and peak NDS were shortened in the two VIP groups.In normal control group, there was no inflammatory cell infiltration or active astrocytes in brain tissue.The degree of infiltration of inflammatory cells and the degree of astrocyte activation in the VIP control group were significantly lower than in the EAE group.The cytokine levels of IFN-γand IL-17A in brain tissue were reduced in VIP groups.Conclusion By lowering IFN-γand IL-17A content in brain tissue, the infiltration of inflammatory cells and astrocyte activation are inhibited.VIP plays an important role in prevention and control of EAE.

[Objective]To observe and analyze the clinical results of ossification of posterior longitudinal ligament(OPLL) combined with high-signal intensity zone(HIZ) change. [Methods]Forty patients with OPLL combined with HIZ were treated from March 2004 to March 2008.Anterior approach surgery was given to 19 cases as group A and posterior approach surgery was given to 21 cases as group P.All cases were followed up.The pre-and post-operative JOA17 scores and improvement ratio were evaluated.[Results]The mean follow-up time were(19.5?3.4) months in group A and(20.3?4.5) months in group P.The mean improvement ratio were(56.2?8.4)% in group A and(52.2?12.2)% in group P.There were no statistical differences between those of groups A and P.Mean JOA scores at last follow-up were(12.8?0.9) in group A and(11.5?1.6) in group P,with significantly difference.[Conclusion]Treatment of OPLL combined with HIZ is a high risk procedure with limited recovery in neoro-function.Good surgical result could be got with correct judgement of type and location of OPLL,occupation ratio of spinal canal and selection of approach.

Objective To explore achillis tendon-sliding procedure and subtalar joint capsula release by the same cut and individualization treatment used in the correction of congenital clubfoot.Methods Forty eight cases (76 feet) of congenital clubfoot who were first visit were treated by achillis tendon-sliding procedure and subtalar joint capsula release by the same cut,meantime,footplate fascia release and transfer of the anterior tibial tenden were made by individualization.Results All cases were followed-up,the average time follow-up was 1 year and 6 months,excellent were 71% and good were 15.7%.Five cases were recurrence and its rate was 6.94%.Conclusions Achillis tendon-sliding procedure and subtalar joint capsula release by the same cut can solve rotation of displacement between calcaneus and talus and individualization treatment can also solve high arch deformity and adduction of foot.This technique is a simple,safe and effective treatment for congenital clubfoot.

Ebosin is a novel exopolysaccharide produced by Streptomyces sp.139 with remarkable activity against rheumatic arthritis in vivo. In this paper, we reported effects of Ebosin on the inflammatory cytokines including interleukin-1beta (IL-1beta), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFalpha) in THP-1 cells. With the special fluorogenic peptide as substrates, the enzymatic activities of interleukin-1beta converting enzyme (ICE) and TNFalpha-converting enzyme (TACE) were inhibited by Ebosin separately. Using the real-time reverse transcription polymerase chain reaction (real-time PCR), the mRNA synthesis of the three cytokines were identified decline separately by Ebosin. The secretion quantum of three cytokines in THP-1 cells with Ebosin was lower than that of normal THP-1 cells determined by ELISA assay and Western blotting. All of these results showed that Ebosin has remarkably suppressed synthesis of the three cytokines in THP-1 cells through different pathways. The primary study of Ebosin on anti-inflammation mechanism was promoted developing the new drugs treating rheumatic arthritis.

Objective To study the clinical effects on patients with brain metastases from lung cancer combined with Elemene Injection and radiotherapy. Method 86 patients with brain metastases from lung cancer were randomly divided into control group and treatment group, 43 cases in each group. Control group was given conventional radiotherapy treatment, while treatment group combined Elemene Injection with radiotherapy. Results Compared with control group, treatment group’s disease control effect was obviously better. Survival rates after treatment for six months, one year, three years were higher than control group, and the number of adverse reactions were lower. Serum MMP-2 and MMP-9 levels were significantly greater. Radiotherapy plan time and total time in hospital for treatment were significantly shorter. Conclusion The combination of Elemene Injection with radiotherapy treatment for patients with brain metastases from lung cancer is very obvious.

Hemorrhagic transformation(HT) is the most severe complication after tissue-type plasminogen activator (tPA) thrombolysis. It greatly limits the clinical application of tPA. Early blood-brain barrier ( BBB) damage may be an important mechanism for HT. Maintaining the integrity of BBB can significantly decrease the risk of HT. This article review s the roles, mechanisms, and preventive measure of early BBB damage in HT after tPA thrombolysis.
