0.05).[Conclusion]It is suggested that reduction of spinal sliding in lower grade LS is not needed after surgical decompression of spinal cord,releasing of nerve root,internal fixation and bone fusion.

Objective To study the expressions of human telomerase reverse transcriptase (hTRT) mRNA and Bax protein in different types of papillary thyroid carcinoma (PTC). Methods hTRT mRNA was detected using in situ hybridization, and Bax protein was detected by immunohistochemistry. Results The positive rates of hTRT were 86.21%,68.97%, 93.33%, 96.43% and 41.79% in PTC, papillary microcarcinoma, intra-thyroid carcinoma, extra-thyroid carcinoma and adjacent tumor tissues, respectively. The positive rate of hTRT expression in the cancer tissues was significantly higher than that in the adjacent tumor tissues (P

Objective To explore the role and significance of the expressions of vascular endothelial growth factor-C(VEGF-C) and its receptors Flt-4 in metastasis of papillary thyroid carcinoma(PTC).Methods The expression levels of VEGF-C and Flt-4 were detected in 87 cases of PTC with SABC immunohistochemical method.Results Among 87 cases of PTC,the positive rates of VEGF-C and Flt-4 were 89.66%(78/87) and 81.61%(71/87),respectively.There was positive correlation between the expression of VEGF-C and Flt-4.The expression of VEGF-C in lymph node metastasis group was significantly higher than that of no lymph node metastasis group(P

Objective To study on the expressions of bFGF, PDGF and TSP-1 mRNA in small intestinal carcinoma and adenoma and their clinico-pathological significance. Methods The specimens were continuously sliced into pieces. The expression of bFGF, PDGF and TSP-1 mRNA was determined by in situ hybridization. Results bFGF, PDGF and TSP-1 was positive in 57%,48% and 36% respectively in 44 cases of small intestinal adenocarcinoma, and was 20%, 30% and 90% in 10 of adenoma respectively. The positivity rates of bFGF mRNA and PDGF mRNA were significantly lower in adenocarcinoma of Ⅰ～Ⅱ grade, without invading muscular layer or invading superficial layer, maximal diameter of tumor mass

Objective To improve the diagnosis and differential diagnosis of adrenal incidentalomas for the optimal management of adrenal masses. Methods The clinical data of 52 cases (35 men and 17 women;mean age,42 years;age range,23-65 years) of adrenal incidentalomas was reviewed.Among them, 33 cases had tumors ≥ 3.0 cm in diameter.None of 52 cases had clinical symptoms and signs of hypertension and endocrine dysfunction.All of the tumors were incidentally found by ultrasonography or CT on regular physical examination.A series of blood chemical examinations (including electrolytes,adrenal cortical and medullary metabolic biochemistry),abdominal ultrasound and CT were performed in all 52 cases;and MRI,PET and  131 I-MIBG imaging were performed in 6,2 and 1 cases,respectively.Surgery and postoperative pathological study were performed in all. Results Postoperative pathology showed adrenocortical adenoma in 27 cases,adrenal metastatic carcinoma in 7,adrenal pheochromocytoma in 5,adrenal cyst in 4,primary aldosteronoma in 3,adrenal neurinoma in 2,adrenocortical carcinoma in 1,retroperitoneal neuroblastoma in 1,retroperitoneal primary lymphoma in 1 and adrenal ganglionic fibroma in 1.Diagnoses based on the results of imaging examinations and laboratory tests were correct in 14 cases (27%).Of the 10 patients with malignancies,5 with primary diseases died 6-10 months after chemotherapy and 5 were lost to follow-up.The remaining 42 patients were followed up for 6 months to 9 years with no evidence of recurrence. Conclusions Multidisciplinary approaches are required to identify and differentiate adrenal incidentalomas, and early surgical treatment is suggested.

OBJECTIVE: To analyze the clinic and pathologic data of thymic epithelial tumor (TET) and to explore its prognostic factors. METHODS: From June 1997 to September 2007, 137 patients with TET were surgically treated in our hospital. The data included age, gender, symptoms, histological type, stage and grade, pathological findings, and operation reports. The patients were followed up by telephones and mails. The patients were divided into Masaoka I/II group and III/IV group, and WHO A/AB/B1 group and B2/B3/C group. Kaplan-Meier method, log-rank test, and COX regression model were used to analyze the prognostic factors for TET. RESULTS: Among the 137 patients, 124 (90.5%) received complete resection, 9 (6.6%) incomplete resection, and 4 (2.9%) surgical biopsy. The rate of complete resection was significantly higher in Masaoka stages I/II than that in stages III/IV (P<0.001). The overall 5-year and 10-year survival rate was 71.4å and 50.1å, respectively. Patients in stage I/II had better long-term survival than those in stage III/IV (P<0.001). According to WHO histological classification, the 5-year and 10-year survival rate in patients with Type A/AB/B1 TET was significantly higher than that in patients with Type B2/B3/C TET (P<0.001). The 5-year and 10-year survival rate in patients with complete resection was significantly higher than that in patients with incomplete resection and biopsy (P<0.001).Cox regression analysis showed that the prognosis of patients with TET was related to Masaoka stage, WHO histological classification, extent of resection, and age at operation. CONCLUSION Masaoka stage, WHO histological classification, extent of resection, and age at operation are important prognostic factors in patients with TET.
