Objective To explore the CT and MR features of malignant peripheral nerve sheath tumor (MPNST) of adults.Methods The CT and MRI findings of 20 patients of MPNST confirmed by pathology were analyzed retrospectively.Results Among 20 cases,the lesions were located in the lower extremities (n=4),shoulder and spine (n=4),abdomen (n=3),chest wall (n=2),mediastinum (n=2),breast (n=1),prostate (n=1),scrotum (n=1),scalp (n=1),left maxillary sinus and orbital bottom (n=1).Nineteen cases appeared as solid masses and 1 case appeared as diffuse lesion.The maximum cross section of the lesions were about 1.41 cm× 1.42 cm-17.10 cm× 18.08 cm.Sixteen cases were ill defined margin and 4 cases were well-defined margin.CT scan showed 14 cases were lower density or isodensity and with patchy inhomogeneous density.Multiple calcification were found in 2 cases and osteolytic destruction were found in 7 cases.Enhanced CT of 10 cases showed solid component and gradually delayed enhancement,while cystic lesion and necrosis were not enhancement.The tortuous arteries were displayed in 7 cases.Seven cases were performed MRI and the lesions appeared as hypo-intensity on T1WI and hypo-intensity on T2WI with obviously high intensity of cystic component.Enhanced MRI of 3 cases showed significantly heterogeneous enhancement,cyst and necrosis had no enhancement.MR dynamic enhancement of 1 case showed time-signal intensity curve was platform type.DWI showed high signal.Conclusion MPNST has certain CT and MR characteristics which are helpful to improve the diagnostic accuracy.

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 investigate the effect of video-based teaching in the training of nursing operation for newly-contracted nurses. Methods One hundred and twenty one nurses newly recruited in September 2011 to September 2012 were set as the control group, another 128 in October 2012 to October 2013 were set as the experiment group. The former were trained and assessed with traditional training method and the latter were trained for 1 year in video-based teaching methodology. After training, both groups were examined about their operation skills and meanwhile a survey on video-based teaching was conducted. Result After training, the results in operating skills evaluation in the experiment group were significantly better those of the control group (Z=2.82, P<0.05). Conclusion Compared with traditional training method, the video-based teaching can raise the level of nursing operation skills and significantly improve the quality of nursing, thus worthy of popularization and application.

Objective To determine the effects of practicing a simplified 24 movement form of Tai chi on the level of inflammatory cytokines and the quality of life of type 2 diabetes patients. Methods A group of type 2 diabetes patients practiced a simplified 24 movement Tai chi routine 60 min/d, 3 d/week for 6 months. Plasma glu-cose and insulin concentration were monitored. The plasma level of IL-6, IL-18, sCD40L, hsCRP and HBAc1 were measured. Changes in the patients' quality of life were also measured by using the SF-36. Results Serum IL-6,IL-18, hsCRP and sCD40L levels were all significantly lower compared with a control group. Significant quality of life improvements were seen in the Tai chi group compared with the controls. Significant reductions were seen in blood pressure, glycated haemoglobin, glucose, insulin resistance and urinary albumin. Conclusions These results sug-gest that regular Tai chi practice can prevent complications and improve the quality of life of diabetes sufferers through glyeaemic control and down-regulating inflammatory cytokine levels.

Background Human leucocyte antigen (HLA)-B27-associated uveitis is one of the most common causes of non-infectious uveitis.T helper 17 (Th17) cells play an important role in human autoimmune diseases,but the pathology research on the production of Th17 cells in acute anterior uveitis patients positive for HLA-B27 was rarely reported.Objective The aim of this study was to investigate the expression and significance of the peripheral blood T helper cell subsets (Th1,Th2,Th17) in acute anterior uveitis patients positive for HLA-B27.Methods This study meets the criteria of the Helsinki Declaration.Informed consent was obtained from all the participants.A prospective cohort design was used in this study.Twenty-two patients with acute anterior uveitis positive for HLA-B27 were enrolled from Affiliated Second Hospital of Nanjing Medical University,and 16 normal healthy subjects with matched gender and age were enrolled as controls.The expression of interferon-γ (IFN-γ),interleukin-4 (IL-4) and IL-17 on lymphocytes (CD4+) in blood were assessed by flow cytometry,and immunoturbidimetry was used to detect the C reactive protein (CRP) level in blood.The degree of the severity of disease was evaluated by clinical scoring.The correlations between the percentage of IFN-γ+Th1,IL-4+Th2,or IL-17+Th17 with clinical factors and CRP were analyzed.Results The percentages of IFN-γ+Th1 and IL-17+Th17 in the peripheral blood were (23.11 ±9.69) ％ and (3.96±2.92) ％ in the patient group,showing a significant increase in comparison with (16.00±4.26)％ and (1.68±0.60) ％ in the control group (P=0.041,P=0.002).However,the IL-4+Th2 level was not significantly different between the patient group (0.33％ ±0.36％) and the control group (0.56％ ±0.34％) (P=0.122).No significant correlations were found between the percentage of IFN-γ+ Th1 with disease severity and CRP (r =0.197,P =0.500 ; r =0.253,P =0.383),between the percentage of IL-4+ Th2 with disease severity and CRP (r =0.068,P =0.817 ; r =0.439,P =0.116) as well as between the percentage of IL-17 + Th17 with CRP (r =0.226,P =0.436).However,a positive correlation was seen between the percentage of IL-17+ Th17 with disease severity (r =0.805,P =0.001).Conclusions IFN-γ and IL-17 in human CD4+T cells are significantly elevated in the blood of HLA-B27-related acute anterior uveitis patients.Disease severity is associated with the percentage of IL-17 +Th17,suggesting that Th1 cells together with Th17 cells participate in the pathogenesis of the disease and Th17 cells might play a dominant role in the disease.

Objective To observe the expression of cardiotrophin-1(CT-1) in ischemia-reinfusion cardiac muscle of rats and the effect of neuregulin-1(NRG-1).Methods The model of ischemia-reinfusion cardiac muscle of rats were prepared,35 rats were randomly divided into 4 groups:model group(n=8),NRG-1 pretreatment group(n=9),pseudo-surgery group(n=8) and normal control group(n=10).The CT-1 mRNA in the observed cardiac muscle of all groups was measured by RT-PCR and the relative amount of CT-1 mRNA were calculated,and for statistical treatment.Results The CT-1 mRNA of model group was(63.96?9.34),and it was higher than that of pseudo-surgery group(36.16?5.43)and normal control group(36.84?4.64).The significant differences were found in 3 groups(F=47.37 P

Objective To optimize and compare four in vitro cytotoxicity assays in order to find a relatively rapid assay that can replace the traditional 51Cr release assay to evaluate the cytotoxicity of immune cells prepared for immunotherapy.Methods Four assays including BATDA, CAM (calcein acetoxymethyl ester), CytoTox-Glo and PKH were optimized and used to measure the in vitro cytotoxicity of NK-92 cells to K562 cell line.Intra-and inter-assay reproducibility of these assays and their correlation with 51Cr release assay were analyzed.Results After optimization, all of the four cytotoxicity assays showed good correlation with effector to target (E/T) ratio in a certain range.Compared with the other three assays, CytoTox-Glo assay showed obvious hook effect at a high E/T ratio of 40∶1.BATDA assay could detect the significant cytotoxicity of NK-92 cells to K562 cells after incubating them for one hour and that was the shortest time taken by the four assays to detect in vitro cytotoxicity.Both CAM and PKH assays took about four hours and CytoTox-Glo assay took six to eight hours to detect the significant cytotoxic potency.All of the four assays, especially BATDA and CAM assays, showed good intra-and inter-assay reproducibility.Among these assays, BATDA assay showed the best correlation with the traditional 51Cr release assay.BATDA assay, as compared with the other three assays, could be used to detect the cytotoxicity of Caov3 cells, an adherent cell line, and showed good results in evaluating the cytotoxic potency of autologous primary NK cells and CD19-CAR T cells.Conclusion Compared with the other three assays, BATDA assay shows the best linear correlation with 51Cr release assay and has the advantages of time-saving and good reproducibility.Besides, it is a better assay for detecting the cytotoxicity of adherent cells.BATDA assay is a promising substitute for 51Cr release assay in evaluating the in vitro cytotoxic potency of NK cells and other immune cells.

Objective To investigate whether the genetic variant rs10830963 of melatonin receptor 1B(MTNR1B)gene is associated with increased risk for gestational diabetes mellitus (GDM).Methods Eighty-seven GDM subjects(GDM group)and 91 normal pregnant women (control group)were randomly recruited form Women and Children's Hospital of Quzhou,Zhejiang Province,China.The allele and genotype frequencies of the rsi0830963 in MTNR1B gene were determined in all participants with PCR amplification and DNA sequencing.The allele and genotype frequencies of rs10830963 were compared to determine their differences between GDM subjects and normal controls.In addition,multiple linear regression was conducted to investigate the association patterns of the risk allele with fasting glucose and HbAlc levels.Results Both GG genotype and G allele frequencies of the rs10830963 loci in the GDM group were significantly higher than those in the controls,and women with G allele and GG genotype were associated with increased GDM risk(OR=1.53,95％ CI:1.005-2.324,P=0.047 and OR=2.16,95％ CI:1.052-4.434,P=0.034 respectively).After adjusting for age,body mass index before pregnancy,and family history of diabetes mellitus,women carrying GG genotype still had a higher GDM risk(OR =2.07,95％ CI:1.048-4.372,P =0.022).Multiple linear regression showed that the rs10830963 G allele was positively correlated with higher levels of fasting glucose(0.068 mmol/L,P=0.015)and HbAlc(0.073％,P=0.028).Conclusions Genetic variant rs10830963 in MTNR1B gene may contribute to the susceptibility to GDM in Chinese population and the rs10830963 G allele is a risk factor for the GDM susceptibility.
