Objective To investigate the ability of T2 mapping in early detection of the change of cartilage collagen by quantitative analysis.Methods 20 porcine patellae were randomly assigned into 4 groups,3 treated groups and 1 control group.The samples of 3 treated groups were respectively immersed in PBS with 100 mg/100 mL,1 50 mg/100 mL and 200 mg/100 mL typeⅡ collagenase for 4 h,whereas control group samples in PBS for 4 h.T2 relaxation times of superficial,deep and full layers of cartilage and mean densi-ty after Van Gieson stain were measured.The correlation of T2 relaxation times and mean density were statistically analyzed.Results Gross pathology showed all articular cartilages maintained intact after treatment.T2 relaxation times of superficial and full layers and mean density increased significantly in any treated group in comparison with control group(P <0.05).Significant differences in T2 relaxation times of superficial layers and mean density were found between any two treated groups,whereas no difference of T2 re-laxation time of full layers was found between 100 mg/100 mL and 1 50 mg/100 mL treated groups(P >0.05).Pearson correlation analysis showed a close correlation(r=-0.837)between T2 relaxation times of full layers and mean density.Conclusion T2 map-ping can adequately detect the change of cartilage collagen in the early stage of osteoarthritis,and shows a good clinical application prospect.

Objective To study the feasibility and safety of measles vaccination in women of childbearing age and to understand the influence of measles vaccination on the fetal transmission measles antibody level of the infants.Methods From January 1,2012 to December 31,2012,600 women of childbearing age were included in this study.The measles IgG antibody was detected,then all participants were randomized according to the IgG level.The measles IgG antibody of participants in non-vaccinated group was detected predelivery in hospital by enzyme linked-immunosorbent assay (ELISA).That of participants in vaccinated group was detected 3 months after vaccination with measles mumps rubella combined vaccine and predelivery by ELISA.And measles nuclear protein fragment gene (measles virus nucleoprotein,MVN) in the blood was detected by reverse transcription polymerase chain reaction (RT PCR).A total of 368 participants gave birth within 2 years after vaccination,and 357 infants 8 months after birth were healthy.In non-vaccinated group,8 infants were diagnosed with measles within 8 months after birth.Finally,349 8-month infants were enrolled in the study,including 52 whose mothers in high antibody without vaccination group,65 whose mothers in high antibody with vaccination group,110 whose mothers in low antibody without vaccination group and 122 whose mothers in low antibody with vaccination group.The measles IgG antibody levels in the blood of all the 8-month infants were detected.Data were analyzed using t test,one-way ANOVA (Newman-Keuls was used for comparison between groups) and Pearson analysis.Results The measles IgG antibody level of expectant women in high antibody without vaccination group was significantly lower compared to that in high antibody with vaccination group ([268.5±74.9] IU/mL vs [578.3t208.1] IU/mL,Q=15.57,P＜0.01).That in low antibody without vaccination group was also significantly lower than low antibody with vaccination group ([169.4+42.3] IU/mL vs [584.7+195.8] IU/mL,Q=29.54,P＜0.01).The results of MVN RT-PCR after 3 months of vaccination showed no positive bands in all blood samples.Two of the expectant women in high antibody without vaccination group and one in low antibody without vaccination group were positive for MVN bands.Among 8-month infants,the levels of antibody in high antibody without vaccination group and high antibody with vaccination group were (106.3 ± 36.8) IU/mL and (291.8±86.5) IU/mL,respectively,which was statistically different (t=23.33,P＜0.01).Those in low antibody without vaccination group and low antibody with vaccination group were (87.1 ± 26.4) IU/mL and (274.0±72.5) IU/mL,respectively,which was statistically different (t =33.27,P＜0.01).The measles antibody level of expectant women was positively correlated with their 8-month infants (r=0.652,P＜0.01).All 8 infants who were diagnosed with measles were delivered by women without vaccination,and the measles infection rate of infants was significantly different between women with and without vaccination (P=0.002).Condusion It is feasible for women of childbearing age to receive measles vaccination,which can increase the measles IgG antibody level of both expectant women and their infants.

In order to solve the problem of selection and in vivo delivery problem in siRNA treatment, hepatitis B virus (HBV) HBx gene which could be targeted by siRNA was studied. The siRNA expression plasmid which specific inhibits HBx expression was obtained by in vitro selection via a dual-luciferase plasmid including HBx-Fluc fusion protein expression domain. The selected siRNA expression plasmid was then encapsulated in PEG-modified cationic liposome, which was devoted into pharmacodynamic studies at both cellular and animal level. The results illustrated that the cationic liposome which encapsulated siRNA expression plasmid could effectively inhibit HBx gene expression both in vitro and in vivo.

ObjectiveTo study the imaging characteristics of SPN of adenocarcinoma (ASPNs) on 18F-FDG PET/CT.MethodsThe morphological and metabolic features of 35 ASPNs on FDG PET/CT were retrospectively reviewed.SUVmax (SUV) was measured and ΔSUVmax was calculated according to ΔSUVmax =(SUVmax on delay imaging - SUVmax on early imaging)/SUVmax on early imaging × 100％.Statistical analysis was performed by software SPSS 11.5 using t-test,analysis of variance and Fisher exact test.Results( 1 ) Fifteen ASPNs (42.86％,15/35) presented as nodular pattern on FDG PET imaging,while 20 (57.14％,20/35) as lamellar,cloudy or ill-defined patterns.The SUVmax of these ASPNs followed a descending order of nodular,lamellar,cloudy and ill:defined on both early and delay imaging (F =30.696 and 24.758,both P＜0.001).(2)There were 54.29％ (19/35) ASPNs with SUVmax ≥2.5 and 45.71％ (16/35) ASPNs with SUVmax ＜2.5.(3) Of 35 ASPNs,24(68.57％ ) were solid nodules and 11(31.43％) were ground glass nodules with SUVmax =4.54 ±2.69 and 1.30±0.87,respectively (t =-5.234,P ＜O.001 ).(4) The SUVmax of ASPNs on delay FDG imaging (4.22 ±3.52) was significantly higher than that on early imaging (3.49 ±2.72) (t =-4.021,P ＜0.001 ).However,SUVmax was dependent on SUVmax on the early imaging:when SUVmax ≥2.5,ΔSUVmax was positive in 94.74％ (18/19) of ASPNs; while SUVmax ＜2.5,ΔSUVmax was positive in 56.25％ (9/16) of ASPNs (P =0.013).(5) Of 31 ASPNs with cell differentiation data,there were 10/17 well-differentiated ASPNs and 13/14 poorly-differentiated ASPNs with positive ΔSUVmax ( P =0.045 ).The average SUVmax of well-differentiated ASPNs was significantly lower than that of poorly-differentiated ASPNs ( 1.70 ± 1.51 vs 4.91 ± 2.69,t =- 3.951,P ＜ 0.001 ).Conclusions The morphological and metabolic features of ASPNs are diversified.It is common for ASPN to present with SUVmax ＜ 2.5.ΔSUVmax may be helpful for differentiating malignant from benign SPNs.

The aim of the present study was to investigate the effect of "nourishing liver and kidney" acupuncture therapy on motor and cognitive deficits,and the underlying mechanism following cerebral ischemia-reperfusion (I/R) via increasing the expression of brain derived neurotrophic factor (BDNF) and synaptophysin (SYN) in the hippocampus.Healthy adult male SD rats were randomly divided into sham operation group (n=51),model group (n=51),acupuncture group (n=51) and acupuncture control group (n=51).The middle cerebral I/R model was established.Acupunctures were performed in the acupuncture group and acupuncture control group at acupoints of Taixi (K103),Taichong (ST09) of both sides,for 30 min once daily every morning.The animals in the sham operation group and model group were conventionally fed in the cage,without any intervention therapy.The rats of each group were assessed with modified neurological severity scores (mNSS).The expression of BDNF and SYN in the hippocampus was detected by immunohistochemical SP method and the synaptic structure in hippocampus area was assessed morphologically and quantitatively at the 3rd,7th and 14th day.The Morris water Maze (MWM) test was used to evaluate the rats' learning and memory abilities on the 15th day after acupuncture.The animals in the acupuncture control group and sham operation group presented no neurological deficit.In the acupuncture group,the nerve functional recovery was significantly better than that in the model group at the 7th and 14th day after modeling.The average MWM escape latency in the acupuncture group was shorter than that in the model group at the 3rd,4th and 5th day.The number of crossings of the platform quadrant in the acupuncture group was significantly more than that in the model group.At the each time point,the expression levels of BDNF and SYN in the hippocampal regions increased significantly in the model group as compared with the sham operation group and the acupuncture control group.In the acupuncture group,the expression levels of BDNF at the 7th and 14th day increased more significantly than those in the model group.In the acupuncture group,the expression levels of SYN at the each time point increased more significantly than those in the model group.The post-synaptic density (PSD) was significantly increased and the synapse cleft width was narrowed in the acupuncture group as compared with other groups.The synaptic curvatures were improved obviously in the acupuncture group in contrast to the model group.It was concluded that the "nourishing liver and kidney" acupuncture therapy has positive effects on behavioral recovery,as well as learning and memory abilities,probably by promoting the expression of BDNF and SYN,and synaptic structure reconstruction in the ipsilateral hippocampus after I/R in rats.The "nourishing liver and kidney" acupuncture therapy can promote the functional recovery in rats after cerebral ischemia injury.

A 15-year-old teenager with Type 1 Neurofibromatosis presented with grade 4 spondylolisthesis over T12/L1 junction resulting paraparesis (Frankel D). Radiograph showed a Cobb angle of 88 degrees. Computed tomography scan showed dysplastic vertebral bodies, pedicles and facet joints of T11, T12 and L1 vertebra with complete T12/L1 facets dislocation. Magnetic resonance imaging confirmed presence of spinal cord compression. He underwent posterior instrumentation and posterolateral fusion (T8 to L4) using hybrid instrumentation. Extensive corticotomy of the posterior elements was followed by the use of large amount of bone graft. Post operatively, his neurology improved markedly back to normal. Radiographs showed a good correction of the deformity. He was immobilized in a thoracolumbar orthosis for six months. A solid posterior fusion was achieved at six months follow up. At 36-month follow up, he remained asymptomatic. This case report illustrates a successful treatment of a grade 4 thoracolumbar spondylolisthesis secondary to neurofibromatosis with posterior spinal fusion alone.
