OBJECTIVETo investigate the role of fascin, an actin bundling protein, in the development and progression of human esophageal squamous cell carcinoma (ESCC), and explore its association with the clinicopathologic characteristics and 5-year survival of the patients.

METHODSUsing tissue array and immunohistochemistry, the expression of fascin was determined in 241 ESCC tissues and the corresponding normal esophageal mucosal tissues.

RESULTSESCC tissues showed a significantly higher overexpression rate of fascin than the corresponding normal esophageal mucosal tissues (68.9% vs 15.5%, P<0.05). The overexpression of fascin was correlated to lymph node metastasis and TMN stage, but not to the patients' age, gender, tumor differentiation and general classification. Survival analysis showed that abnormal expression of fascin was associated with the 5-year survival rate of patients with ESCC.

CONCLUSIONSThe abnormal expression of fascin may play an important role in the progression of ESCC, and detection of fascin expression may have important prognostic values.

OBJECTIVETo investigate the changing of T4 5'-and 5-deiodinase within rat brain under various iodin-nutritional states.

METHODSAnimal model of iodine-deficiency rat was performed and the rats were divided into 4 groups by the intake of iodine-nutrition, and then killed at an age of 20 days. The thyroid hormones level in serum was measured by ELISA and the activity of T(4) 5'-and 5-deiodinase within brain was analyzed.

RESULTSIn less-iodine (LI) group,TT4 and FT4 were accounting for 3.5% of the neutral-iodine (NI) group's, and FT3 was 174.0% of NI group's (P < 0.05). In NI group,TT4 and FT4 were 114.5% and 127.7% of NI group's (P < 0.05). In high-iodine (HI) group, TT4 and FT4 were 61.86% and 62.0% of NI group's, and FT3 was 184.9% of NI group's (P < 0.05). In LI group, the activity of T4 5'-deiodinase tissue of per gram (1.95 +/- 0.32) ngT3.microgT4(-1).h was significantly higher than that of NI group (P < 0.05), and the activity of 5-deiodinase (1.38 +/- 0.21) ngrT3.microg T4(-1).h(-1) is significantly less than that of NI group (1.59 +/- 0.23) (P < 0.05). In HI group the activity of T4 5'-and 5-deiodinase tissue of per gram (1.12 +/- 0.19 and 1.73 +/- 0.36) ngrT3.microgT4(-1).h(-1)was significantly less than that of NI group (P < 0.05).

CONCLUSIONThe activity of T4 5'-deiodinase in iodine deficiency heightens and that in iodine excess is debased, the activity of T4 5-deiodinase in iodine deficiency and in iodine excess is debased.

Objective To explored effective methods of care for outpatient with PICC intermittent treatment to reduce plugging risk of peripherally inserted central venous catheter (PICC),and to ensure the patient comfort and safety in catheter use.Methods There were 436 cases with PICC between January and September in 2010 in the control group,which received the routine nursing.And 459 cases between January and September in 2011 as the study group,which received the nursing from Quality Control group.Quality Control (QC) group analyzed the causes in catheter blockage of the outpatients with PICC on intermittent treatment and then made some nursing interventions for study group.Then,the incidence of complication and plugging pipe were observed and compared between the two groups.Results One year later,the complications of outpatients relating with PICC in study group were obviously decreased than that in control group (14.81％ vs 20.41％,x2 =4.844,P ＜ 0.05).In all of complications,catheter blockage rate 2.40％ vs 5.05％,and catheter pulling rate (0.22％ vs 1.38％) in study group were lower than that in control group,and the differences were statistically significant (x2 =4.420,3.866,respectively; P ＜ 0.05).Conclusions QC care activities can notably reduce the complications of outpatients with PICC treatment on intermittent period,which will be an effective way to elevate the quality of care,and improve life quality of the patients.

Objective To investigate the efficacy and tolerability of a recombinant human tumor necrosis factor:Fc fusion protein (rhTNFR:Fc,with a trade name of Yisaipu) in the treatment of moderate to severe psoriasis vulgaris.Methods A multicentre,randomized,double blind,and parallel-controlled trial was performed.One hundred and forty-four patients with moderate to severe psoriasis vulgaris from four centres were randomly assigned and treated with either once-weekly subcutaneous injection of rhTNFR:Fc (50 mg) or oral methotrexate (MTX)(7.5 mg) for 12 weeks.Patients were followed up at 2,4,8,12 weeks after the treatment.Results One hundred and twenty-four patients finished the 12-week course of treat- ment.At 12 weeks after the treatment,a 50%,75%,90% improvement in psoriasis area and severity index (PASI) was achieved by 86.11%,76.39%,52.78% respectively of rhTNFR:Fc-treated patients,and by 63.89%,44.44%,22.22% respectively in MTX-treated patients,and all the three improvement rates were of significant difference between the two groups of patients (all P0.05).Conclusion Compared with MTX,rhTNFR:Fc acts more quickly with a higher cure rate and less toxic reactions in the treatment of psoriasis vulgaris.

OBJECTIVETo explore the pathophysiological and biomechanical features of skeletal muscular injury for providing a rational basis for its treatment, prevention and rehabilitation.

METHODSIn 70 adult rabbits, the left tibialis anterior (TA) muscle was stretched to injury, while the right TA muscle served as control. Histological, enzymohistochemical and biomechanical changes were observed on days 0, 1, 2, 3, and 7 after injury. Cytochrome oxidase (CCO), acid phosphatase (ACP), ATPase, succinate dehydrogenase (SDH), malate dehydrogenase (MDH), NADH-diaphorase (NADHD), glutamatedehydrogenase (GDH), alpha-glycerophosphate dehydrogenase (alpha-GPD) and lactate dehydrogenase (LDH) were measured. The examined biomechanical parameters included maximal contractile force, ultimate load, length, energy absorption, tangent stiffness, and rupture site.

RESULTSPartial or complete rupture of TA muscle occurred near the muscle-tendon junction. There was an intense inflammatory reaction on day 1 and 2 after injury. Endomysium fibrosis and myotube formation were observed on day 3, and developed further on day 7. The activity of cell oxidases (CCO, ATPase, MDH, alpha-GPD, SDH, NADHD and GDH) showed a significant drop from day 0 to 2, and resumed with different levels on day 3. The increment of enzymatic activities continued on day 7 and the levels of NADHD and alpha-GPD reached to the levels of control muscle. Maximal contractile force was 70.17%+/-3.82% of controls immediately after injury, 54.82%+/-3.09% at 1 day, 66.41%+/-4.36% at 2 days, 78.39%+/-4.90% at 3 days and 93.64%+/-5.02% at 7 days. Ultimate load was 85.78%+/-7.54% of controls at the moment of injury, 61.44%+/-5.91% at 1 day, 49.17%+/-4.26% at 2 days, 64.43%+/-5.02% at 3 days, and 76.71%+/-6.46% at 7 days.

CONCLUSIONSEndomysium fibrosis and scar formation at the injured site are responsible for frequent recurrence of skeletal muscle injury. Recovery of tensile load slower than that of maximal contractile force may be another cause. Whether the injured muscle returns to normal exercise is mainly determined by the tensility on which the muscle-tendon can bear rather than the maximal contractile force.
