Objective To explore the effect of methylprednisolone combined with interferon in the treatment patients with relapse remitting multiple sclerosis.Methods 90 patients with relapse remitting multiple sclerosis were randomly divided into experimental group and treatment group.The experimental group during the acute stage with methylprednisolone pulse therapy,remission with interferon β (IFN-β) treatment; the control group only in the acute phase with methylprednisolone pulse therapy.Results The total effective rate of methylprednisolone pulse therapy in the acute stage was 98.9％.Experimental group during the treatment with IFN-β1α,relapse rate was 30.2％ ;patients in the control group were followed up for two years,the recurrence rate was 53.3％.Experimental group and control group was significantly different ( P ＜ 0.05 ),the experimental group was significantly lower than the control group.Conclusion For relapsing-remitting MS,using MPPT could relieve acute symptom in the acute stage,and in remission using of IFN-β1α relapse prevention was a good choice for clinicians.

This study was aimed to evaluate effects of traditional Chinese medicine ( TCM ) five elements music therapy on the quality of life for both senior and non-senior advanced cancer patients , and improve TCM com-prehensive treatment mode . A total of 170 patients were stratified according to 70-year-old in a randomized controlled trial ( RCT ) with a parallel single-blind design . The ratio of patients among three groups was 2:2:1 . In the experimental group , TCM five elements music was given in the treatment . In the positive control group , western music was used in the treatment . And in the negative control group , no music was given in the treat-ment . The treatment was given for 30 min , 5 times per week . And the observation duration was 3 weeks . The Hospice Quality of Life Index-Revised ( HQOLI-R ) , Karnofsky Performance Scale ( KPS ) and Symptom Diary Score recorded by patients were used in the evaluation . The results showed that when comparing HQOLI-R , KPS and Symptom Diary Score before and after treatment among all advanced cancer patients in each group , there was a significant difference before and after treatment in the TCM five elements music therapy group ( P< 0 . 05 ) . But there was no significant difference before and after treatment in the western music therapy group or the negative control group ( P > 0 . 05 ) . It was concluded that TCM five elements music therapy is effective in improving quality of life and subjective symptoms for both senior and non-senior advanced cancer patients . However , the sensitivity of using the Symptom Diary Score as an evaluation index among senior patients still needs to be further proved .

The cell-free plasma DNA (cfpDNA) has been suggested as a useful tumor marker for its quantitative and qualitative tumor-specific alterations that reflect the biological characteristics and the progression and outcomes of tumors.Therefore,it has been used as liquid biopsy to detect cfpDNA in peripheral blood for the diagnosis,monitoring of clinical effects,and prognosis of malignancies

Objective To evaluate the effects of parecoxib sodium for preemptive analgesia in patients undergoing cerebral angiography. Methods Sixty patients undergoing cerebral angiography were divided into two groups by random digits table with 30 cases in each : group P and group F. Patients in group P received parecoxib sodium 40 mg 30 min before operation, while group F received fentanyl 1 μ g/kg 2 min before operation. The changes of hemodynamics were observed before operation (To), immediately right internal carotid artery angiography during operation (T1), immediately right vertebral artery angiography (T2),immediately left internal carotid artery angiography(T3), immediately left vertebral artery angiography(T4), 10min after operation (T5). The mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2)and visual analogue score (VAS) were recorded at different times during the whole operation. Results There were no significantly differences on MAP, HR and VAS between group P and group F (P ＞ 0.05 ). But the SpO2 at T1 ,T2,T3 in group F (0.94±0.03,0.95±0.02,0.95±0.02) were significantly lower than those in group P (0.98 ± 0.01,0.98 ± 0.02,0.98 ± 0.02 )(P＜0.05 ), and 2 cases SpO2 ＜ 0.90 at Ti. Conclusion Parecoxib sodium administered preemptively provides a nice analgesic effect in patients undergoing cerebral angiography, and is more safe than fentanyl.

Objective To evaluate the differences of the lower extremity atherosclerosis between patients with and without type 2 diabetes using dual-source CT angiography.Methods Dual-source CT angiography of lower extremity was performed in 87 patients with (n=30)or without (n= 57 )diabetes.Extent of luminal stenosis,and the type,distribution and range of the plaques were compared.Results 342 plaques in 540 segments (63.3%)in diabetic patients,and 500 plaques in 1 026 segments (48.7%)in non-diabetic ones were detected respectively.Compared with non-diabetic patients,the diabetic ones had a higher overall incidence of plaques (P <0.05).Calcified plaques were the most common in both kinds of patients,and the incidence of mixed plaques was high-er in diabetic patients than that in non-diabetic ones (35.6 % vs.28.4%,P <0.05).Light to moderate stenosis occurred in most diabetic patients,and fewer occlusion was found compared with non-diabetic ones (9.1% vs.1 7.0%,P <0.05).The most common sites of the plaques in diabetic patients were located at distal small arteries below the knee.However,those were located at proximal arteries above the knee for non-diabetic ones.The involvement of atherosclerosis in diabetic patients was more diffused,and the de-gree of Ⅳ (75%-100%)was higher than that in non-diabetic ones (P <0.05).Conclusion Atherosclerosis in lower extremity on dual-source CT angiography is very common in diabetic patients with multi-segmental,diffused,non-obstructive involvement of dis-tal small arteries below the knee.

Aim To evaluate the effects of ferulic acid ( FA ) on lipopolysaccharide ( LPS )-induced neuroin-flammation in microglia cells and its potential mecha-nisms. Methods Microglial activation was induced by stimulation with LPS, and the effects of FA pretreat-ment on microglial activation and production of proin-flammatory mediators, nitric oxide/iNOS were investi-gated. The role of the mitogen-activated protein kinases in the antiinflammatory actions of FA in LPS-stimulated microglia was further elucidated. Results Cell viabil-ity experiments revealed that FA did not produce cyto-toxicity in microglia. FA significantly inhibited LPS-in-duced production of tumour necrosis factor-alpha ( TNF-α) , interleukin-6 ( IL-6 ) , interleukin-1 beta ( IL-1β) , and nitric oxide ( NO ) . Protein and mRNA levels of COX-2 and inducible nitric oxide synthase ( iNOS) were also attenuated by FA. Further experi-ments on intracellular signalling mechanisms showed that inhibition of extracellular regulated kinase ( ERK) contributed to the anti-neuroinflammatory actions of FA. Conclusion The results suggest that FA inhibits LPS-induced microglial inflammation by partial targe-ting of ERK signalling and attenuation of ERK.

Objective To investigate the roles of theaflavins(TFs) in airway mucus hypersecretion induced by human neutrophil elastase(HNE). Methods Human lung adenocarcinoma cell A549 was stimulated by HNE for mucus hypersecretion,and TF monomers(TF1,TF2 and TF3) were used for intervention.The effects of TF monomers on viability of A549 cells were examined by MTT method.After the effective doses of TFs were determined,A549 cells were divided into 4 groups for experiment.In control group,A549 cells were cultured with serum-free medium.In HNE treatment group,A549 cells were treated with HNE(50 nmol/L) for 24 h.In TF monomer intervention groups,A549 cells were pre-treated with TF1,TF2 or TF3(50,100 or 200 ?g/mL) for 24 h,and were then treated with HNE for another 24 h.In AG1478 intervention group,A549 cells were pre-treated with AG1478(5 ?mol/L),an epidermal growth factor receptor blocker for 30 min,and were then treated with HNE for another 24 h.The changes in mucin(MUC) after treatment by different doses of TF1,TF2 and TF3,and by TF3(200 ?g/mL) for different time(12 h,24 h and 36 h) were detected.The changes in MUC5AC mRNA expression and MUC5AC protein expression were detected by RT-PCR and ELISA,respectively. Results The MUC5AC mRNA expression and protein expression in HNE treatment group were significantly higher than those in control group(P

Objective To compare the short-term efficacy of high-intensity ultraviolet B (UVB) versus 308-nm excimer laser for the treatment of vitiligo.Methods Eighty patients with vitiligo were equally divided into two groups to be treated with high-intensity UVB twice a week or 308-nm excimer laser once a week for eight weeks.Repigmentation was evaluated at the end of the treatment.Results After eight weeks of treatment,repigmentation of different degrees was observed in 83.6％ and 86.1％,and marked repigmentation in 42.1％ and 50％,of the UVB-and excimer laser-treated lesions,respectively.The response rate was significantly lower in facial lesions receiving high-intensity UVB radiation than in those receiving excimer laser radiation (49.1％ vs.68.4％,x2 =4.32,P ＜ 0.05),but similar at the other body sites between the two treatment (all P ＞ 0.05).The cumulative dosage required for initial repigmentation was similar between high-intensity UVB and 308-nm excimer laser (t =0.89,P ＞ 0.05),while the treatment sessions and cumulative dosage required for marked or better repigmentation were significantly increased in UVB-compared with excimer laser-treated lesions (both P ＜ 0.01).In addition,both high-intensity UVB and 308-nm excimer laser were suitable for childhood and active vitiligo.Conclusions Both high-intensity UVB and 308-nm excimer laser are safe and effective in the treatment of vitiligo with rapid onset of action,and the latter appears to be superior to the former in efficacy.

Objective To compare the biomechanical performance of three different fixation instruments for tibial fractures.Methods Fourteen fresh tibial specimens were made into models of oblique fracture.Seven models were fixed with unilateral axial dynamic fixation(UADF),and seven with limited contact dynamic compression plate(LC-DCP).After biomechanical tests had been done for the UADF group,an extra screw was used at the oblique fracture site to reinforce the fixation with extra limited internal fixation.Each model was tested for its hiomechanical performance in resisting compression,bending and rotation.Results The performance of UADF was significantly poorer than that of LC-DCP and UADF with limited internal fixation in anti-compression,an- ti-bending and anti-rotation(P＜0.05).There was no significant difference in the rigidity between LC-DCP and UADF with limited internal fixation(P＞0.05).Conclusion UADF with extra limited internal fixation is a recommendable method for tihial fractures because it cart provide the same effective fixation as LC-DCP does.

Objective To obtain recombinant human Smith D1 (Sm D1) antigen and establish detecting assay.Methods Human Smith D1 antigen was synthesized by PCR using human Leukemic cDNA. The prokaryotic expression vector pGEX-ST-Sm D1 was constructed and transformed into E.coli.BL21 cell.Protein expressed under the induction of IPTG.We established DIGFA for detecting anti-Sm D1 antibodies with purified Sm D1 antigens.Results Sequence and restriction analysis revealed Sm D1 gene was cloned in frame into pGEX-5T,SDS-PAGE profile showed a clear protein band with a relative molecular weight of 39 000 and western blotting indicated that the expressed product specifically reacted to polyclonal anti-human Sm D1 genes.There was no significant difference between DIGFA and IB.The agreement between DIGFA and IB was 91.7% as calculated by Kappa statistical method.The sensitivity and specificity of DIGFA were 100% and 83.3% repectively.Conclusions Human Sm D1 gene is successfully cloned、 expressed and purification.The DIGFA,using purified Sm D1 antigens,is as good as IB,rather simpler, more rapid and reliable assay.
