Objective To investigate the clinical features,diagnosis,treatment and prognosis of gastric neuroendocrine carcinoma (G-NEC).Methods Clinical data of 52 G-NEC cases were analyzed.Follow-up was conducted by telephone.The survival curves were drawn using Kaplan-Meier method.Univariate analysis was performed by the Log-rank test and multivariate analysis was performed by COX proportional hazards model.Results The median overall survival rate was 19 months (range 6 to61 months),and the overall 1,3,5-year survival rates were 74%,16% and 5% respectively.Tumor stage surgery,vascular nerve involvement and Ⅲ and Ⅳ phase chemotherapy were related to prognosis (x2 =24.254,10.005,7.261,8.790,all P < 0.05).Multivariate analysis showed tumor stage and vascular nerve involvement were independent prognostic factors (x2 =17.170,5.810,all P < 0.05).Conclusion G-NEC is a highly malignant tumor with poor prognosis.Preoperative diagnosis rate is low.Surgery is the treatment of first choice.Definite diagnosis depends on postoperative pathology and immunohistochemical examination.

ObjectiveTo investigate changes of the level of serum thyroxine after different style operation on thyroid gland,for guiding replacement therapy after surgery. MethodsTo select patients randomly,include the excision of adenoma of thyroid、the lobectomy of unilateral thyroid、the subtotal ectomy of bilateral thyroid and total resection of bilateral thyroid quaque forty,among the total,the patients who suffererd the total resection of bilateral thyroid take thyroxine 40mg bid orally everyday. To detect the serum thyroxine in all of the patients, when preoperation、ten days after operation、one month after operation and three months after operation. ResultsThe serum thyroxine in patients who suffererd the excision of adenoma of thyroid were had no marked changes compare to preoperation; Serum FT3 、FT4 in patients suffer the lobectomy of unilateral thyroid are lower than preoperation when ten days after operation (P<0.01) ;Serum FT3、FT4 in patients sufferred subtotal ectomy of bilateral thyroid were lower than preoperation,when ten days after operation and one month after operation( P < 0.01 ), then returned to the level of preoperation when three months after operation;the serum thyroxine of patients who sufferred the total resection of bilateral thyroid had no marked changes compare to preoperation,when they taker thyroxine 40mg bid orally everyday. ConclusionThe serum thyroxine level of patients who suffer the lobectomy of unilateral thyroid、the subtotal ectomy of bilateral thyroid and total resection of bilateral thyroid is lower than preoperation at different degree, they should be given replacement therapy properly.

AIM: To investigate the potential role of 14-3-3 tau in trophoblast cells on invasiveness. METHODS: 14-3-3 tau expression was detected in first-trimester villi, deciduas and human trophoblastic cell line (BeWo) by immunohistochemistry. Small interference RNA (siRNA) targeting 14-3-3 tau was transfected into BeWo cells. The effects of down-regulated 14-3-3 tau on invasion of human trophoblasts cell line BeWo were examined by matrigel invasion assay, and the transcription, translation of E-cadherin and snail were estimated by RT-PCR or Western blotting. U0126 was used to detect the extracellular-signal related kinase 1/2 (ERK1/2) function on down-regulation of 14-3-3 tau induced cell invasion. RESULTS: 14-3-3 tau was detected in the invasive trophoblastic cells in the first trimester villi and that invaded to the deciduas. BeWo cells also expressed 14-3-3 tau. Down-regulation of 14-3-3 tau increased the invasive cell-number of BeWo, as well as the expression of snail, and inhibited E-cadherin. U0126 inhibited the enhanced invasiveness in these cells induced by the down-regulation of 14-3-3 tau. CONCLUSION: 14-3-3 tau may regulate the invasiveness of human trophoblastic cells through ERK1/2 signaling pathway.

Objective:To establish a liquid chromatography-mass spectrometry(LC-MS) method for determining the concentration of amlodipine besylate in human plasma and to evaluate the bioequivalence of 2 kinds of amlodipine besylate tablets.Methods: Twenty healthy male volunteers were enrolled into a single crossover study.A single dose of the suspension equivalent to 10 mg amlodipine besylate or a reference preparation was given in a crossover way.The plasma concentrations of amlodipine besylate were determined by LC-MS method in the volunteers at different time points;the pharmacokinetic parameters and relative bioavailability were calculated and the bioequivalence of the 2 preparations were evaluated.Results: The pharmacokinetic parameters for experimental and the reference preparations were: C_max(6.21?1.88) vs(6.03?1.08) ng/ml;AUC_0-120(250.68?52.61) vs(246.14?52.11) ng h/ml;T_max(6.0?2.3) vs(6.1? 2.5) h;t_1/2(40.45?6.68) vs(43.74?9.05) h,respectively.The linear range of the present method was 0.1-20.0 ng/ml;the lowest detectable concentration of amlodipine besylate was 0.1 ng/ml.There was no significant difference in pharmacokinetic parameters between the 2 tablets.Conclusion: The present method is simple to use,fast,and accurate.The 2 preparations of amlodipine besylate are bioequivalent.
