Thyroglossal duct carcinoma is a malignant tumor which occurs in the thyroglossal duct cyst. The incidence of thyroglossal duct carcinoma has been reported as approximately 1%. Up to now, just about 250 cases of thyroglossal duct carcinoma have been reported in the literature,most of which are single case reports and small case series. In most cases, the diagnosis of the thyroglossal duct carcinoma is not made until the histologic examination after surgery operation. The preoperative examination such as CT or fine needle aspiration cytology can help the preoperative diagnosis. But the surgical treatment for the thyroglossal duct carcinoma is still controversial. Now we report a case of a thyroglossal duct carcinoma combined with systemic lupus erythematosus. The patient herself found an anterior neck mass in the median submental region one year ago. The preoperative CT examination suggested thyroglossal duct cyst with pouch canceration(papillary carcinoma). Then she underwent a Sistrunk procedure and level I neck dissection, and the histopathological diagnosis was thyroglossal duct carcinoma. The patient was treated with levothyroxine therapy at suppressive dose after the surgery. Now the patient is at regular follow-up with no relapse occur.

Objective To investigate the clinical application of CT perfusion imaging in assessing the hemodynamic changes in patients with small hepatocellular carcinoma (<5 cm) before and after transcatheter arterial chemoembolization (TACE). Methods Twelve patients with small hepatocellular carcinoma were enrolled in this study. CT perfusion imaging of the liver was performed 1 - 2 days before and 3 - 4 weeks after TACE. By using the perfusion parameters the hemodynamics of the preoperative and postoperative tumor tissue, the hemodynamics of the preoperative tumor tissue and the normal tissue, and the hemodynamics of the postoperative active tumor tissue and the normal tissue were determined , and the results were compared between each other. Results Before TACE, the blood flow (BF), hepatic arterial fraction (HAF), hepatic arterial perfusion (HAP) and permeability of surface (PS) in the tumor tissue were significantly higher than those in the normal tissue (P < 0.01), while after TACE all the perfusion parameters except blood volume (BV) were significantly decreased in the tumor tissue (P < 0.01). After TACE, BF, PS, HAF and HAP in the activity tumor tissue were increased more than those in the normal tissue (P < 0.05). Conclusion CT perfusion imaging is of great clinical value in diagnosing < 5 cm hepatocellular carcinoma , in evaluating the hemodynamic changes after TACE and in demonstrating the activity of the residual tumor tissue.

BACKGROUND:The therapeutic effects of donkey-hide glue reinforcing bone oral solution on osteoporosis have been determined, but the exact effective mechanism is to be approached. OBJECTIVE: To investigate the effects of donkey-hide glue reinforcing bone oral solution (DGRBOS) medicated serum on osteoprotegerin (OPG)and its ligand(OPGL)mRNAexpression of osteoblast in fetal rats and explore the molecular mechanism of treating osteoporosis with DGRBOS. DESIGN: A randomized controlled trial. MATERIALS: The experiment was carried out from June 2003 to October 2004 in Bone Metabolic Laboratory of Department of Integrative Chinese and Western Medicine, Affiliated Hospital of Tongji Medical College,Huazhong University of Technology and Science. Totally 30 3-month-oldWistar rats (15 males and 15 females) were randomly divided into 3 groups, I.e. DGRBOS group, estrogen group and control group, with 10 rats in every group. 12 clean newborn SD rats were selected to isolate and cul ture osteoblast. METHODS: ①After intragastric administration for 7 days, medicated serum was prepared respectively from the three groups. ②Skull osteoblast isolated from newborn SD rats was made into single cell suspension, then after digestion and passage, the subcultured osteoblast cell was made into cell suspension. The cultured osteoblasts were divided into 5 groups and given equal volumes of drug liquor. The DGRBOS group was given DGRBOS-medicated serum at the concentration of 100, 500 and 1 000 g/L which was diluted by nutrient solution; the estrogen group was given tibolone-medicated serum of 100 and 1 000 g/L; the control group was givenonly culture fluid. Meanwhile every group was given calf serum (100 g/L) for further culture. ③The osteoblast proliferation was measured by antigenic MTT colorimetric analysis and 3H-TdR penetration method. The in tra-cellular BGP contents were evaluated by radioimmunity .The mRNA expression of OPG and RANKL in osteoblast was analyzed by Rt-PCR. ④ One-way analysis of variance was applied to compare data among groups. MAIN OUTCOME MEASURES: mRNA expression of OPG and PAN KL in osteoblasts from fetal rats after intervention by medicated serum ofDGRBOS or Livial. RESULTS: ①The osteoblast proliferation measured by antigenic MTT colorimetric analysis and 3H-TdR penetration method showed that the proliferation in the DGRBOS group and tibolone group was enhanced moresignificantly than that in the control group (P ＜ 0.05-0.01), and reached maximal effect at the concentration of 500 g/L (P ＜ 0.01), but when the concentration was over 500 g/L, the effect tended to saturate. The medicated serum with all concentrations from DGRBOS and estrogen groups could increase the contents of BGP in osteoblasts (P ＜ 0.05). ②The mRNA expression of OPG reached the peak when the DGRBOS medicated serum was 1 000 g/L, and was obviously higher than that at the concentration of 100 and 500 g/L (P ＜ 0.05). The expression in DGRBOS group at the concentration of 1 000 g/L and in the estrogen group at the concentration of 100 and 1 000 g/L was apparently higher than that of the control group (P ＜ 0.01). ③The mRNAexpression of RANKL was the highest in DGR BOS group with 1 000 g/L concentration, and was markedly lower than that of the concentration of 100 and 500 g/L (P ＜ 0.05). The expression in DGRBOS group at the concentration of 1 000 g/L and in the estrogen group at the concentration of 100 and 1 000 g/L was noticeably lower than that in the control group (P ＜ 0.01).CONCLUSION: ①The DGRBOS could remarkably enhance osteoblast proliferation in dose-dependent and a dose-saturable manner, and the effect was close to that of tibolone. ②Partial mechanism of DGRBOS in treating osteoporosis might be promoting osteoblast proliferation and regulating OPG/RANKL expression.

We retrospectively reviewed the clinical records of 12 systemic lupus erythematosus (SLE) patients with thrombotic thrombocytopenic purpura (TTP) admitted into Peking Union Medical College Hospital (PUMCH) during October 2008 to September 2013.TTP occurred in 0.45％ (12/2 693) of patients with SLE.The median age (2 males,10 females) was 23 years.Their SLEDAI scores ranged from 12 to 30.All patients had significant thrombocytopenia and renal abnormalities.Ten of them bad acute renal failure.Cardiac involvement and neurological deficits were observed in 9 and 8 of them respectively.Eight of them had injuries of more than 4 organs.Renal biopsy of 3 patients revealed lupus nephritis (type Ⅳ,n =2 ; type Ⅴ,n =1) and thrombotic microangiopathy.Eleven TTP patients received steroid pulse therapy (1 g/d,3 days) and six of them survived.Six patients were rescued by therapeutic plasma exchange and 4 of them recovered.Among another 6 patients not on plasma exchange therapy,only 3 recovered.Finally 2 died,3 gave up with exacerbated symptoms after therapy and 7 survived.
