Objective:To investigate the protein expression levels of breast cancer metastasis suppressor 1 (BRMS1) and Con-nexin 43 (Cx43) in thyroid cancer and their correlation with clinicopathologic parameters. Methods:Immunohistochemistry Streptavi-din-Peroxidase method was used to detect the BRMS1 and Cx43 protein expression in 195 tissue samples, including 90 cases with thy-roid carcinoma, 45 cases with thyroid adenoma, 30 cases with nodular goiter, and 30 cases with normal thyroid glands. Results:The positive rates of BRMS1 and Cx43 expression was 56.7%(51/90) and 41.1%(37/90) in thyroid carcinoma, respectively, which are sig-nificantly lower than the rates in thyroid adenoma, nodular goiter, and normal thyroid gland tissues (P<0.001). Of the three pathological types of thyroid cancer, the positive expression rate of Cx43 was 61.9%in papillary carcinoma, 27.8%in medullary carcinoma, 27.3%in follicular carcinoma, and 12.5%in undifferentiated carcinoma. Statistical differences in the BRMS1 expression among papillary car-cinoma and the other pathological types were also noted. Unlike the patients without lymph node metastasis, the positive expression of BRMS1 and Cx43 proteins were both significantly low among patients suffering from nodal metastasis. Subgroup analysis shows that the positive expression of BRMS1 and Cx43 protein gradually decreased with TNM staging. In addition, a positive correlation was ob-served between the BRMS1 and Cx43 protein expression (r=0.494, P=0.032). Conclusion:The decreased expression of BRMS1 and Cx43 proteins is significantly correlated with the metastasis of thyroid cancer and malignant grade. The combined detection of the two proteins can be ideal biomarkers for judging the prognosis of thyroid carcinoma.

OBJECTIVE:To provide reference for rational use of antidepressant drugs in the clinic. METHODS:By DDD anal-ysis recommended by WHO,the utilization of antidepressant drugs in 34 hospital from Nanjing area during 2011-2014 were ana-lyzed statistically in respects of main type,consumption sum,DDDs and DDC,etc. RESULTS:The consumption sum and DDDs of antidepressants were increased year by year in 34 hospital from Nanjing area during 2011-2014,with the average annual growth rate of 18.21% and 19.25% respectively. The top 2 drugs by DDDs were paroxetine and setraline;DDC of tomoxetine,trazodone and dutoxetine took up the first 3 place;consumption sum of paroxetine,setraline,venlafaxine and escitalopram took up the first 4 places;consumption sum of paroxetine,mirtazapine and citalopram synchronized with their DDDs,and serial number ratio was close to or equal to 1.00. CONCLUSIONS:The use of antidepressant drugs in 34 hospitals from Nanjing area is rational in struc-ture and level;selective 5-hydroxytryptamine(5-HT)reuptake inhibitors(SSRI)and selective 5-HT noradrenaline reuptake inhibi-tor(SNRI)take up the predominant place;new type of antidepressant drugs are used widely and of great use potentiality in the fu-ture.

With the development of drug discovery, more and more candidate compounds need to be studied. Methods that can screen compound rapidly received significant attention. Parallel artificial membrane permeability assay (PAMPA) as a powerful tool has been applied to drug studies. It uses an artificial lipid membrane to mimic the barrier for drug permeability studies. This article introduces the establishment and characteristics of PAMPA, as well as its applications in screening compounds. It can be used as models (e.g. predicting the ability of compound in gastro-intestinal absorption, blood-brain barrier transportation and skin penetration) by changing the component of artificial lipid membrane. PAMPA has advantages in high throughput selection of valuable compound with low cost, versatile, low dose, and good reproducibility.

Objective: To study the expression of cyclin D1 and E in lung cancer. Methods: The immunohistochemical technique was used to detect the expression of cyclin D1 and E in 68 cases of non small cell lung cancer(NSCLC) and 21 cases of small cell lung cancer(SCLC). Results: The rate of cyclin D1 protein positive expression was 48.5% in NSCLC, 4.8% in SCLC,showing significant difference( P

Animals for model of osteoporosis involve rat, mouse, rabbit, beagle dog, minipig, sheep, etc. The types of model include aged related model, ovariectomized model, orchietomied model, drug treated model, abolition degeneration model, and dietary bone loss. The rat with ovariectomized model is used widely. Biochemical determination, bone mineral density measurement, bone histomorphorphormetry and bone biomechanics are used to judge the formation of experimental osteoporosis.

Objective To investigate the characteristics in vitro and hemostatic function of O -carboxymethyl chitosan multi-hemostatic sponge. Methods Freeze-drying technology was applied on preparation of O -carboxymethyl chitosan hemostatic sponge. The physicochemical properties of the self-produced multi-hemostatic sponge were observed for its appearance, porosity rate,water absorption,and density. The hemostatic effect was compared between the self-produced hemostatic sponge and commercially available absorbable gelatin sponge in rabbit models with ear venous and arterial injuries. Results The self-produced hemostatic sponge was off-white and full of pores with good tenacity and even net texture. Its porosity ratio, water absorption rate, and density were 67. 23%,38. 77%,and 0. 043 4 g·(cm3)-1,respectively. The bleeding time volume were significantly lower from the self-produced sponge than that from the commercially available gelatin sponge. No secondary re-bleeding was observed. Conclusion The self-produced O -carboxymethyl chitosan multi-hemostatic sponge displays stable physicochemical characteristics and reliable hemostatic effect.

Objective To study the influence of combined anti-CD-40L and low dose CsA immunotherapy on the induction of immune tolerance in orthotopic liver transplantation rats.Methods Recipients were divided into the following groups.Group A,SD→SD;Group B,SD→Wistar without any treatment;Group C,SD→Wistar with CsA therapy from d1 to d5;Group D,SD→Wistar with CsA from d1 to d5 and anti-CD40L mAb in d0 and d2,and Group E,SD→Wistar with CsA from d1 to d5 and anti-CD40L mAb in d0 and d2 plus autotransfusion before operation.The recipient survival time,histologic changes of allograft and the level of cytokines in peripheral blood were observed.Results The survival period of recipients in Groups A,D and E was significantly longer than that in Groups B and C.The acute rejection response in Groups D and E decreased prominently.The serum level of IL-2 and IFN-? in Group B were significantly higher than those in other groups,while the serum level of IL-4 and IL-10 in Groups D and E was elevated much more than those in Group B(P

Objective To know the influence of passive smoking on children's immune function. Methods The smoking state of children's family members and the illness-induced absence state of 135 children aged 10-11 years were investigated with questionnaire, and the concentrations of immunoglobin E (IgE) and interleukin 8 (IL-8) in serum of children were examined. Results The concentrations of IgE in serum of the children exposed to passive smoking(n=30) were significantly higher than those of the control group(n=20), while the concentrations of IL-8 were significantly lower(both P

Objective To evaluate the role of MRA,IPVG and DUS in the hemodynamics studies of portal hypertension.Methods Thirty-eight patients with portal hypertension were examined with Philips Gyroscan 1.0 Tesla MR imaging system.3D-DCE MRA and 2D-PC MR were used for study of portal venous anatomy and its hemodynamics.The results were compared with those obtained from IPVG and DUS.Results 3D-DCE MRA could clearly display the anatomical imaging of portal venous system and its imaging quality was better than that of IPVG.The data of hemodynamics from 2D-PC MR including diameter,blood velocity and blood flow were closely correlated to those from DUS.Conclusion As a non-invasive technique,MRA can display the anatomy of portal venous system and measure its hemodynamics exactly.It should be applied as the first choice in hemodynamics evaluation for portal hypertension.
