Objective To study the expression of KAI1 and CD40 in gastric cancer and their correlation with clinicopathologic features and prognosis.Methods The expression of KAI1 and CD40 of 64 gastric cancer tissues was examinated by S-P immunohistochemieal methods.Results The overall positive rate of KAI1 was 22% in gastric cancer.Expression of KAI1 was positively related to the degree of tumor differentiation,it was negatively related to invasion depth and lymph node metastasis and the tumor clinical stage.The 5-year survival rate of cases with positive expression of KAII was significantly higher than that of cases with negative expression(X~2=42.426,P=0.000).The expression rate of CD40 in gastric cancer tissue was 34%.The expression of CD40 was significantly correlated with metastasis and clinical stage of gastric cancer.The 5-year survival rate of cases with positive expression of CD40 was significantly lower than that of cases with negative expression(X~2=4.841,P=0.028).There is no relationship between KAI1 and CD40 expression in gastric cancer.Conclusion KAI1 is associated with gastric cancer differentiation,invasion and metastasis.CD40 status helps to evaluate metastasis,and predict prognosis of gastric cancer.

Objective To determine the reference intervals for thyroid function tests during the second half of pregnancy (20-40 gestational weeks),and to assess the relationship between thyroid peroxidase antibody (TPOAb) levels and the incidence of gestational thyroid diseases.Methods Levels of thyroid stimulating hormone (TSH),free thyroxine (FT4),TPOAb and urinary iodine excretion were determined in 4 729 pregnant women,who received prenatal health care at First Affiliated Hospital of Nanjing Medical University from July 2011 to August 2013.Among these women,2 568 were selected using the recommendations of the American National Academy of Clinical Biochemistry,and were divided into five groups according to their gestational age:≥ 20 to ＜24 weeks (682 cases),≥ 24 to ＜28 weeks (1 322 cases),≥ 28 to ＜32 weeks (178 cases),≥ 32 to ＜36 weeks (185 cases) and ≥ 36 to ≤ 40 weeks (201 cases).Reference intervals of thyroid function tests in the second half of pregnancy were calculated.The reference values of thyroid functions in different gestational weeks were compared,and the reference intervals of thyroid functions in the second half of pregnancy were determined.The effects of maternal age and positive TPOAb on gestational thyroid diseases were analyzed.A non-parametric test,analysis of variance or Chi-square test was used for statistical analysis.Results (1) Reference intervals for maternal thyroid function in the second half of pregnancy in our hospital were established [TSH:0.65-5.27 mU/L and FT4:8.74-14.84 pmol/L].(2) The percentage of thyroid diseases was higher using the non-pregnancy reference intervals (TSH:0.27-4.20 mU/L and FT4:12.00-22.00 pmol/L) than using the pregnancy reference intervals [64.0％ (3 025/4 729) vs 16.1％ (763/4 729),x2=47.465,P ＜ 0.01],which manifested as a higher rate of clinical hypothyroidism and simple hypothyroxinemia [5.4％ (255/4 729) vs 0.4％ (20/4 729),x2=14.321;54.1％ (2 560/4 729) vs 9.1％ (429/4 729),x2=47.108;both P＜0.01] and a lower rate of subclinical and clinical hyperthyroidism [1.2％ (58/4 729) vs 3.3％ (155/4 729),x2=6.650;0.3％ (13/4 729) vs 0.6％ (27/4 729),x2=2.062;both P＜0.05].(3) The incidence of clinical hypothyroidism and simple hypothyroxinemia in pregnant women aged ＞30 years was higher than in those aged ≤ 30 years [0.7％ (10/1 377) vs 0.3％ (10/3 352),x2=4.257;11.7％ (161/1 377) vs 8.0％ (268/3 352),x2=16.102;both P＜0.05].The incidence of clinical hypothyroidism and clinical hyperthyroidism in TPOAb positive women was higher than that in TPOAb negative women [2.7％ (9/335) vs 0.3％ (11/4 394),x2=44.009;3.9％ (13/335) vs 1.2％ (52/4 394),x2=16.784;both P＜0.01].Conclusions The established pregnancy-specific reference ranges of thyroid function tests can reduce the missed diagnosis and misdiagnosis of gestational thyroid diseases.Maternal age ＞30 years and positive TPOAb may increase the risk ofgestational thyroid diseases.

Objective To analyze the causes for diffuse bone marrow uptake of 18F-FDG on PET/CT scans. Methods Sixty-six patients with diffuse bone marrow uptake on whole-body FDG-PET/CT imaging were enrolled for this study. Seventy-nine healthy subjects ( with no history of tumor or recent fever) were selected as normal control. The SUVmax and SUVmean were measured in bone marrow and mediastinum in both groups. The maximum (bone marrow SUVmax/ mediastinum SUVmax) and mean value ratios (bone marrow SUVmean/ mediastinum SUVmean) were calculated. Statistical analysis was performed by one-factor variance analysis. Results With diffuse bone marrow uptake pattern of 18F-FDG, 27 were caused by injection of hematopoietic growth factor, 21 by hematopathy and 18 due to fever. SUVmeanof those three causes were 3.076±1.955, 3.633±2.405 and 2.546±0.791 respectively, each was significantly different from that of the control group (1.026±0.190; F =34.465, P<0.001). Conclusion Diffuse bone marrow uptake on FDG-PET/CT are caused by both benign and malignant reasons.

Objective To report the clinical effects of microsurgery in treatment of infected extremities after blood vessel prosthesis were transplanted.Methods From Jan.1998 to Dec.2008,8 cases of major vascular injuries in extremities were blood-supplied by cross bridge vascular anastomosis from uninjured extremities,including 4 cases of femoral artery and vein,2 cases of popliteal artery and vein,and 2 cases of brachial artery and vein. Results After 3 years of follow-up,blood circulation of infected extremities were reestablished in each of 8 cases,as well as function and appearance recovered.Conclusion The procedure of cross bridge vascular anastomosis from uninjured extremities may efficiently restitute the blood supply of the infected extremities after blood vessel prosthesis were transplanted,and decrease the rate of amputation.

Objective To explore the role of serum S-100B concentration of umbilical cord blood and blood on the 24 h after admission in the early diagnosis and development of newborn hypoxic-ischemic encephalopathy(HIE).Methods Forty-six HIE newborns(31 cases with mild HIE and 15 cases with moderate and severe HIE)were selected as HIE group,and 43 normal full-term newborns were selected as control group.The umbilical cord blood sample and blood sample were aquired on the 24 h after admission.The serum S-100B concentration was detected by enzyme-linked immunosorbent assay(ELISA)analysis.Results 1.There was no significant difference of serum S-100B concentration between the male sub-group and female sub-group of normal group and their birth weight had no significant relative to the serum S-100B concentration.2.The serum S-100B concentration of umbilical cord blood of control group and HIE group were(1.03?0.32)and(2.53?1.1)?g/L,respectively,there was significant difference between two groups(t'=8.848 P

Objective To evaluate the effects of 131 adrenoceptor anfisense on blood pressure and?1 adrenoceptor mRNA and protein levels in 2 kidney 1 clip(2K1C)rats.Method 2KIC hypertensive rots were produced by clipping renal artery of SD rats.Liposome/AS-ODNs 2.0 were tested intravenously in rats with 2KIC hypertension.Animals were divided into 5 groups(n=18 in each group):?1-AS-ODN group,?1-IN-ODN group,2K1C group,Sham group and SD group.Blood pressure was measured by tail-cuff method,the levels of myocardial?adreneceptor mRNA and protein were tested by RT-PCR and binding assay.Results On the basis of the magnitude and duration of hypotension,?1-AS-ODN decreased blood pressure by 39 mmHg at the most for 4 weeks.Compared with the 2KIC group,?1-AS-ODN did not significantly change the levels of myocardial?1 adrenoceptor mRNA but significantly decreased the levels of myocardial?1 adrenoceptor protein at 2,7,30 days (P

OBJECTIVETo investigate the underlying mechanism of the protective effects of resveratrol on oxidant-induced mitochondrial damage in embryonic rat cardiomyocytes.

METHODSH9c2 cells, a permanent cell line derived from embryonic rat cardiac tissue, and then randomly divided into control group [PBS, cells exposed to H2O2 (600 µmol/L) for 20 min to induce mitochondrial oxidant damage], resveratrol group (0.01, 0.1, 1, 5, 10 and 20 µmol/L for 20 min at 20 min before exposing to H2O2), resveratrol plus inhibitor group (1 µmol/L KT5823 for 10 min at 10 min before 5 µmol/L resveratrol treatment) and inhibitor group (1 µmol/L KT5823 for 10 min). Mitochondrial membrane potential (ΔΨm) was measured by staining cells with tetramethylrhodamine ethyl ester (TMRE) and the mitochondrial permeability transition pore (mPTP) opening was evaluated by measuring the decrease of TMRE fluorescence intensity. Immunofluorescence assay was used to observe GSK-3β phosphorylation. The phosphorylation of GSK-3β and VASP were determined by Western blot. To detect intracellular NO, cells were loaded with DAF-FM DA (specific fluorescent dye of NO) and imaged with confocal microscopy.

RESULTSCompared to the control group, resveratrol (0.01-5 µmol/L) attenuated H2O2-induced mitochondrial damage reflected by attenuating the H2O2-induced TMRE fluorescence intensity decrease in a dose-dependent manner and the efficacy of 10 and 20 µmol/L resveratrol was significantly lower than that of 5 µmol/L resveratrol. Resveratrol also significantly upregulated the protein expression of VASP and increased GSK-3β Ser(9) phosphorylation, which could lead the inactivation of GSK-3β. These effects of resveratrol could be significantly abolished by protein kinase G inhibitor KT5823, while KT5823 alone did not affect GSK-3β and VASP phosphorylation. Confocal microscopy showed that DAF-FM (specific NO indicator) was similar between resveratrol and control group, suggesting that resveratrol did not produce NO.

CONCLUSIONSResveratrol could attenuate oxidant-induced mitochondrial damage in embryonic rat cardiomyocytes by inactivating GSK-3β via cGMP/PKG signaling pathway independent of NO-related mechanism.
