Objective To investigate the image characteristics of Synovial Sarcoma, and improve the diagnostic accuracy. Methods The clinical materials and image findings of synovial sarcomas proved by pathology and were retrospectively analyzed in 13 cases.Results ①Most synovial sarcomas located in close proximity to joints, especially large joints of lower limbs . ②The mass diameter was usually more than 5cm ,and most masses presented moderate density, and some with calcification inside it on X-ray films. ③Most masses density was not homogeneous and lower than that of the muscle on CT, the demarcation was clear or not. ④On T2WI /STIR of MRI, most tumours presented slightly hyperintense "cobble" nodules , with hypointense septa among the nodules. After contrast, the nodules were unenhanced or enhanced slightly,the septa were markedly enhanced. Conclusion Some image features of synovial sarcoma ,especially on MRI, are helpful for the diagnosis of it.

Objective To observe the effect of thymic peptide on the serum levels of IL-10 and IFN-? in patients with varruca planea and the effect of treatment.Methods Double-antibody sandwich ELISA was used to detect the serum levels of interleukin-10(IL-10) and interferon-gamma(IFN-?) in normal persons and varruca planea patients with thymic peptide and control before and after treatment.Results Before treatment,the serum levels of IL-10 were significantly higher in patients,while the levels of IFN-? were significantly lower than that in normal people(P0.05).The levels of IL-10 in the thymic peptide group were lower than those of control group,while the levels of IFN-? were higher than those of control group after treatment (p

Objective To compare the analgesic efficacy and side effects of patient-controlled intravenous analgesia (PCIA) with Lornoxicam and patient-controlled epidural analgesia(PCEA) with morphine in patients undergoing Orthopaedics surgery. Methods 100 ASA Ⅰ-Ⅱ Patients scheduled for Orthopaedic surgery were divided randomly into two groups: Lornoxicam PCIA group( n =50) , Lornoxicam 48mg was diluted to 100ml with normal saline (0.9%NS). Morphine PCEA group( n =50), Morphine 9mg + bupivacaine 150mg were diluted to 100ml with normal saline (0.9%NS) .In both groups the patients were received PCA at a rate of 2ml/h with the bolus dose of 0.5ml and lockout interval of 15min. The loading dose was Lornoxicam 8mg plus Ondansetron 4mg in group PCIA and morphine 1mg and Ondansetron 4mg diluted to 10ml with normal saline (0.9%NS) in group PCEA 30 minutes before the end of operation. BP, RR, ECG, SpO_2 were monitored continuously after operation. Efficacy of analgesia was assessed by VAS scores. Side effects such as drowsiness, sweat, nausea, vomiting and skin pruritus were also observed. Results There was no significant difference in the mean VAS score between group PCIA and group PCEA at 4h, 8h, 16h ,20h, 24h, 32h and 48h. after operation. There was no significant difference in side effects between the two groups except the occurrence of sweat, nausea, vomiting and skin pruritus which was lower in group PCIA than in group PCEA ( P

Objective To observe the effect of acupuncture plus early-stage rehabilitation training on the neurological function and levels of serum ischemia-modified albumin (IMA) and neuron-specific enolase (NSE) in patients with acute cerebral infarction.Method Sixty-eight patients with acute cerebral infarction were randomized into a treatment group and a control group, 34 cases each. The control group was intervened by conventional medications, while the treatment group was intervened by acupuncture plus early-stage rehabilitation training in addition to the medications given to the control group. The two groups were both treated once a day, 10 d as a treatment course. Three treatment courses later, the changes of serum IMA and NSE levels were observed; the Modified Edinburgh-Scandinavian Stroke Scale (MESSS), Barthel Index (BI) and Fugl-Meyer Assessment (FMA) scores were compared before and after the treatment.Result The MESSS, BI and FMA scores were significantly changed in both groups after the intervention (P<0.01). After the intervention, the MESSS, BI and FMA scores in the treatment group were significantly different from those in the control group (P<0.05). The serum IMA and NSE levels were significantly changed in both groups after the intervention (P<0.01). After the treatment, the serum IMA and NSE levels in the treatment group were markedly lower than those in the control group (P<0.01).Conclusion Acupuncture medication combined plus early-stage rehabilitation training can promote the recovery of neurological function of acute cerebral infarction patients, which is related to the down-regulation of serum NSE and IMA levels.

OBJECTIVE: To investigate the mRNA and protein expression of MICA in laryngeal squamous cell carcinoma tissue and the Hep-2 cells. METHOD: Reverse transcriptase-polymerase chain reaction (RT-PCR) and Western-blot were used to detect the expression of MICA mRNA and protein levels in the Hep-2 cells and laryngeal cancer tissues. RESULT: The MICA mRNA showed higher expression in Hep-2 cells by RT-PCR. Compared with the control, the mRNA expression of MICA was significantly enhanced in laryngeal cancer tissues (t = 11.878, P < 0.01). The intensity of MICA expression is not related to the clinical stage of cancer. MICA protein demonstrated higher level expression by Western blot. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. CONCLUSION The MICA mRNA showed stronger expression in Hep-2 cells and laryngeal cancer tissues. The intensity of its expression is not related to clinical stage of cancer. The MICA protein expression was strong in Hep-2 cells. The intensity of MICA protein expression was decreased with increased clinical stage in laryngeal cancer tissues. MICA may play an important role in laryngeal carcinoma process.

Objective:To elucidate the role of ERK1/2 MAPKs signal transduction in the protective effects of ischemic preconditioning during liver transplantation. Methods: Twenty-four rats were equally randomized into 4 groups: sham control (group A); liver transplantation (group B); ischemic preconditioning+liver transplantation (group C), and MEK inhibitor intervention+ischemic preconditioning+liver transplantation (group D). Serum AST and ALT were detected after operation and cellular ultrastructures were observed by transmission electron microscopy. Liver tissue ERK1/2 MAPKs phosphorylation activities were evaluated through determining ERK-1 protein phosphorylation by Western blotting. Results: Serum ALT and AST activity in group B and group D was significantly higher than those in group A, and remained normal in group C. Liver tissue ERK1/2 MAPKs phosphorylation activity increased significantly in group C, and the activation effect was inhibited in group B and D. Cellular ultrastructure was obviously damaged in group B and group D, and the damage was prevented in group C.Conclusion: Ischemic preconditioning has a protective effect on transplanted liver cells in which ERK1/2 MAPKs pathway plays a pivotal role.

Objective To investigate the effect of miR-27a mimic and inhibitor on proliferation and apoptosis in melanoma cell line WM239. Methods The miR-27a mimic,inhibitor and its negative control were transfected into WM239 cells. The transfection efficiency was evaluated by fluorescence microscope. The expres-sion of miR-27a was detected by real-time fluorescent quantitative PCR. The proliferation of cells was detected by MTT. The cell apoptosis and cell cycle were analyzed by flow cytometry. Results The transfection efficiency in WM239 cells was 80% to 90%. The expression of miR-27a was markedly up-regulated in miR-27a mimic group (2-△△CT value is 26. 98 ± 0. 01),with statistically significant difference(t= -1 123. 67,P=0. 00);and the miR-27a inhibitor group showed lower expression of miR-27a(2-△△CT value is 0. 96 ± 0. 02),there was no statisti-cally significant difference compared with normal control group(t=0. 04,P=0. 06). The proliferation of cells was obviously inhibited in miR-27a mimic group,and there was statistically significant difference compared with normal control group[absorbance of 72 h(0. 45 ± 0. 02)∶(0. 72 ± 0. 01),F=129. 56,P﹤0. 05]. The percent-age of WM239 cells in G0-G1 phase was increased[(74. 83 ± 1. 46)∶(63. 73 ± 1. 25),F=30. 33,P﹤0. 05], and the percentage of WM239 cells in S phase and G2-M phase were decreased[(21. 33 ± 1. 75)∶(27. 50 ± 1. 25),F=14. 98,P﹤0. 05;(3. 90 ± 1. 31)∶(8. 80 ± 2. 10),F=3. 66,P﹤0. 05]. The apoptosis rate of cells was significantly increased in miR-27a mimic group compared with normal group[(29. 67 ± 0. 91)%∶(1. 44 ± 0. 85)%,F=530. 90,P﹤0. 01],but the inhibitor group had no obvious effect on cell cycle and cell apoptosis. Conclusion MiR-27a can suppress melanoma cell proliferation and act as a tumor suppressor gene,which is rel-evant to induce cell apoptosis and block cell cycle in G0-G1 phase.
