Objective To evaluate CT guided 125I seeds implantation for liver metastasis of colorectal cancer. Methods The retrospective analysis was undertaken in 15 colorectal cancer patients with 33 foci of hepatic metastases from Jul 2006 to Aug 2007, receiving CT guided 125I radioactive seeds implantation according to TPS or Halarism's experience function: mCi = Da × 5, Results All the patients were followed-up by CT scan after 3 months. There were 2 of complete remission (CR) , 10 of partial remission (PR), 3 of stable disease (SD). All patients are still alive now, the lougest follow-up time is 20 months, and the shortest is 6 months, the average followed span is 12 months. Conclusion CT guided 125I seeds implantation is a safe and effective method in the treatment of liver metastasis caused by colorectal cancer.

ObjectiveTo investigate the cumulative incidence of persistent hypothyroidism in patients who were diagnosed as postpartum thyroiditis ( PPT),and to determine the factors associated with the development of persistent hypothyroidism in those patients.MethodsThe present study was performed as the continuous study followed by the former epidemiological survey on PPT,in which 58 patients with PPT (35 overt PPT and 23 subclinical PPT) were diagnosed.The 58 patients were followed up at 12th month postpartum,and then for every 6 months until 24 months postpartum.Fasting blood samples were taken for testing serum TSH,thyroid peroxidase antibody ( TPOAb),and thyroglobulin antibody ( TgAb ).Free T3 ( FT3 ),free T4 ( FT4 ),and TSH receptor antibody ( TRAh ) were detected if TSH was abnormal.50 healthy postpartum women were used as control group.ResultsOf the total 58 PPT patients,91,4% ( n =53 ) were successfully followed.Five patients with overt PPT and 6 patients with subclinical PPT developed persistent hypothyroidism,and the cumulative incidence of persistent hypothyroidism in the studied PPT patients was 20.8%.Among 15 PPT patients who had a classical biphasic course (a thyrotoxic phase followed by a hypothyroid phase),persistent hypothyroidism was seen in 26.7% (n =4 ).Among 11 PPT patients with hypothyroidism only,persistent hypothyroidism was seen in 63.6% ( n =7).On the contrary,none of the patients with thyrotoxicosis only had persistent hypothyroidism.All of the patients who developed persistent hypothyrodism had a higher TSH levels than 4.8 mU/L at 6th month postpartum.Before delivery,TSH levels of the patients developed persistent hypothyroidism were significantly higher than those of the patients with transient hypothyroidism,and this was the case at the 12th month postpartum ( all P<0.01 ).PPT patients maintained a relatively higher rate of thyroid autoantibodies.The positive rate of TPOAb at the 12th,18th,and 24th month postpartum was 56.6%,50.9%,and 52.8%,respectively; and the positive rate of TgAb being 35.8%,30.2%,and 30.2%,respectively.Both the positive rate and titer of TPOAb in patients with overt PPT were higher than those in patients with subclinical PPT at the 18th and 24th month postpartum (P<0.05).Conclusions 20.8% patients with PPT developed persistent hypothyroidism at the 24th month postpartum.Whether a patient with PPT would develop persistent hypothyroidism depends on his clinical feature and TSH level.

Objective:Cholangiocarcinoma (CCA) is a malignant tumor derived from bile duct epithelial cells with extremely poor prognosis. The Hippo-Yes-associated protein (YAP)/transcription activator with PDZ binding motif (TAZ) signaling plays a critical role in cancer stem cell biology. Previous studies have shown that the positive expression of YAP/TAZ in CCA predicts larger tumor size and unfavorable clinical outcomes. We aim to evaluate the prognostic value of YAP/TAZ detection in CCA patients.Methods:CCA patients who underwent radical resection were retrospectively analyzed at our institution from January 2011 to June 2016. Postoperative pathological specimens were scored by YAP/TAZ immunohistochemical staining. The prognostic value of YAP/TAZ was analyzed by multivariate Cox-proportional hazards model.Results:A total of 91 CCA patients were enrolled. During a median follow-up time of 11.0 months, 69.2% patients relapsed and 45.1% died. The median OS and DFS were 10.7 months and 8.8 months respectively. The YAP/TAZ dual positive patients owned a worse TNM stage ( P=0.015), poorer tissue differentiation ( P=0.007), and a higher CA199 than those in negative patients. Multivariate Cox analysis identified that YAP/TAZ dual positivity as a significant factor predicted poorer OS ( P=0.010) and DFS ( P=0.028) in CCA patients after radical resection. In subgroup analysis, YAP/TAZ combination also significantly predicted OS ( P=0.044) and DFS ( P=0.043) in CCA patients with positive lymphatic metastasis and/or surgical margin who required adjuvant therapy. Conclusions:YAP/TAZ positivity is an independent predictive factor for survival in CCA patients after radical resectiony.
