Two 78-years old-old man and woman presented with thyroid tumor without a past history of chronic thyroiditis. Physical examinations showed touchable lumps in thyroid without other lymph nodes swelling or extra nodal lesions. Two cases both had thyroid function test, color Doppler ultrasound examination, computed tomography (CT) scan and fine needle aspiration (FNA) before surgery. The patients underwent partial thyroidectomy or subtotal thyroidectomy. Postoperative pathologic findings were consistent with malignant lymphoma. The diagnosis mainly relied on the postoperative pathologic findings.

Objective The aim of this study was to discuss the technical details on laparoscopic total cyst excision with Roux Y hepatoenterostomy for the treatment of choledochal cyst in children.Methods Eight patients with type Ⅰ choledochal cyst (median age 3 6 years) underwent laparoscopic cyst excision with Roux Y hepatoenterostomy from July 2001 to April 2002.Under laparoscopic guidance, intraoperative cholangiogram was performed, the gallbladder and the dilated bile duct were completely excised. Roux en Y jejunojejunostomy was performed extracorporeally through umbilical incision (2 cm), and an end to side anastomosis was carried out intracorporeally.Results Median duration of operation was 4 8 hours (3 6 to 6 0 hours), intraoperative bleeding was between 10 to 50 ml. Hospital stay after the operation ranged from 3 to 8 days. There was no intra or postoperative complication.ConclusionLaparoscopic total cyst excision with Roux Y hepatoenterostomy was effective and safe procedure for children with choledochal cyst.

Objective To explore the distribution of alkane, alcohol and ketone in indoor air of some apartments in Hangzhou. Methods 55 air samples were randomly collected from 31 apartments in Hangzhou by Carbotrap 300 air-sampling tube, during October-December, 2002, and April-May, 2003, then the volatile organic compounds in air samples were determined by heat-desorption GC-MS. Results 41 kinds of alkane, 11 kinds of alcohol and 9 kinds of ketone were found in air samples collected from 31 apartments in Hangzhou, average concentration of total alkane was 24.096 7 ?g/m3, average concentration of total alcohol was 3.670 7 ?g/m3, and average concentration of total ketone was 33.492 4 ?g/m3 respectively. The dominant indoor air pollutants were hexane, heptane, octane, nonane, decane, undecane, dimethylbutane, methylhexane, n-butanol, cyclohexanone, propanone, 2-butanone. The concentrations of alkane, alcohol and ketone in indoor air of apartments decreased with the time went on after the house decoration finished on the whole. 10 of 14 alkanes showed positive correlation to the temperature, 6 of them to the relative humidity at the sampling points. 2 of 11 alcohols and 3 of 9 ketones showed positive correlation to the relative humidity at sampling points. Conclusion The increasing temperature is the important factor for the release of alkanes in indoor air. The increasing relative humidity is the influence factor for the release of alcohols, ketones, and some alkanes in indoor air.

Objective To study the feasibility and efficacy of laparoscopic operation for choledochal cyst. Methods Under laparoscopy,intraoperative cholangiography was performed.The dilated commom bile duct and the gallbladder were excised,a Roux-en-Y cholangio-jejunostomy was constructed outside the abdominal cavity. Results 5 babies underwent the total cyst excision and hepato-cholangio-jejunostomy successfully and quickly recovered.Only a girl transferred to open operation because of previous operative history. Conclusions Laparoscopic treatment of choledochal cyst is feasible and satisfied outcome.

Objective To investigate the role of Stathmin in pancreatic cancer invasion and metastasis and its relationship with DNA methylation. Methods Immunohistochemical detection of MBDI and Stathmin protein expression in 40 cases of pancreatic cancer and 15 cases ot normal pancreatic tissue were performed,followed by analysis of their clinical and pathological relationship with pancreatic cancer; Human pancreatic cancer cell line BxPC-3 was treated with 5-Aza-2-dC (AZA).Both qRT-PCR and Western blot analysis of Stathmin expression were used before and after AZA treatment; Stathmin-siRNA transfected BxPC-3 cells were divided into the Stathmi-siRNA group and the empty vector control group.Transwell chamber invasion assay and animal experiment were performed to measure the changes in cell invasion and metastatic capability. Results lmmunohistochemistry showed positive MBDI and Stathmin expressions in 28 (70％) and 24 (60％) out of 40 cases of pancreatic cancer,respectively,which were significantly higher than that in the normal pancreatic tissue (P＜ 0.05); MBDI and Stathmin protein expressions were positively correlated (r =0.356,P =0.037),so were MBDI expression and lymph node metastasis (P=0.023).Stathmin expression was significantly correlated with clinical staging and lymph node metastasis (P =0.002,and P =0.001,respectively).After AZA treatment,both Stathmin mRNA and protein expression in BxPC-3 were significantly decreased.Transwell chamber invasion assay showed that compared with the control group,the cell invasion capability of the Stathmin-siRNA group was significantly decreased (P＜0.05).Animal experiment showed that the incidence of liver metastasis was significantly lower in the Stathmin-siRNA transfected group than the empty vector control group (P＜0.05).Conclusion Demethylation may contribute to the reduction of Stathmin expression in pancreatic cancer and further improve the prognosis of pancreatic cancer patients.

Objective To explore the antitumor mechanism of xianhe yanling recipe( XHYLR ). Methods The mechanism of action of 241 compounds contained in the Chinese medicine, XHYLR was studied by using computational pharmacological. Methods including molecular docking,biotechnology network,chemical space technology and the prediction of absorption,distribution,metabolism,excretion and toxicity( ADME/T). Results Most of the compounds in XHYLR had good drug-like properties. Distribution of 241 compounds in chemical space also revealed that these compounds showed similar anti-tumor activity. It suggested that the prescription of XHYLR was reasonable. The phenomena that one molecular interacted with multiple target proteins and several molecules interact with one target protein were observed in XHYLR. For example,the COX-2 interacted with 40 micromolecules,and catechin interacted with five targets including COX-2. Conclusion These results are helpful for understanding the complicated mechanism of anti-tumor activity of XHYLR.

Objective To assess the value of multi-slice spiral CT angiography (MSCTA) in diagnosis of posterior nutcracker syndrome (NCS). Methods MSCTA of 15 patients clinically diagnosed as posterior NCS (patient group) and 50 subjects with normal renal vessels (control group) were retrospectively analyzed. The anatomy, course and relationship to the adjacent structure of left renal vein (LRV) and its branches were observed. The anteroposterior diameter (d1) and cross areas (s1) of the angle of control group and posterior abdominal artery (AA), the anteroposterior diameter (d2) and cross areas (s2) at the largest lumen near the renal hilar were measured and the ratio of s2/s1 and d2/ d1 were calculated.Results All LRVs posterior AA of patient group were compressed and narrowing with dilating apparently near the renal hilar. The difference of d2 was not significant (P＞0.05), but of other values were significant (P＜0.05).Conclusion MSCTA can show anatomy and three-dimentional trend clearly of LRV for posterior NCS, and evaluate the extent of narrow and dilating lumen accurately with cross areas measuring.
