Objective To evaluate the clinical value of high-resolution ultrasound for predicting the extracapsular extension (ETE) of papillary thyroid cancer (PTC).Methods A total of 151 nodules with PTC in 116 patients confirmed by surgery and pathology were enrolled.The ultrasonographic characteristics were retrospectively analyzed,and the percentage of the perimeter of the nodule that abutted the thyroid capsule (A) were observed.Taking A≥1％,A≥25 ％ and A≥ 50％ as cutoff value respectively,the ETE of PTC was predicted.Results Of the 151 nodules with PTC,ETE presented in 59 (59/151,39.07％),while no ETE (non-ETE) was observed in 92 (92/151,60.93％).Nodules in the thyroid parenchyma (A0) which could be observed with ultrasound was 84 (84/151,55.63％),and 1％≤A＜25％,25％≤A＜50％andA≥50％ was 25 (25/151,16.56％),15 (15/151,9.93％),and 27 (27/151,17.88％),respectively.There were statistically significant differences of nodules between the non-ETE and ETE when A≥1％,A≥25 ％ and A≥50％ (all P ＜0.01).Taking A=50％ as the cutoff value for predicting the presence of ETE,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value was 37.29％ (22/59),94.57％ (87/92),72.19％ (109/151),81.48％ (22/27) and 70.16％ (87/124),respectively.Conclusion High frequency ultrasonography can effectively predict whether PTC has been invaded,which provides important reference information for preselected surgical approach and prognosis of patients.

BACKGROUND: Some studies have presented that vascular endothelial growth factor and its receptor system may take part in onset and development of diabetic nephropathy (DN).OBJECTIVE: To further verify the interventional effects of irbesartan on vascular endothelial growth factor (VEGF) and its Flk-1 receptor expressions in kidney of diabetes mellitus (DM) rat, and the possible mechanism of irbesartan.DESIGN: Randomized control animal study.SETTING: West China Hospital of Sichuan University.MATERIALS: Eighteen male closed colony SD rats weighing 150-200 g were cared in standardization.METHODS: This study was performed at Laboratory of West China Hospital of Sichuan University from August 2006 to April 2007. All rats were randomly divided into a DN group, an irbesartan group and a normal control group, with 6 rats in each group. 10 g/L streptozotocin (55 mg/kg) was intraperitoneally injected to establish models; rats in the control group were administrated with the same dosage of citric acid buffer solution; rats in the irbesartan group were administrated with 3 mg/(kg·d) irbesartan after model establishment. VEGF and FIk-1 expressions were detected using reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry technique; while, urine protein level, area and volume of renal glomerulus were detected, and correlations of data were analyzed.MAIN OUTCOME MEASURES: ①Renal pathological indicators, urine protein level, area and volume of renal glomerulus; ②VEGF and Flk-1 expressions;③renal immunohistochemical examination;④ correlation analysis.RESULTS:① Renal pathological examination by HE staining indicated that renal glomerulus was remarkably enlarged in the DN group; mesangial matrix was increased; mesangial cells were also increased; renal tubule was expanded. The lesions in the irbesartan group were milder compared to the DN group. Urine protein level in the DN group was significantly higher compared to the control group (P ＜ 0.01); renal weight/body mass, area and volume of renal glomerulus were significantly higher compared to the control group (P ＜ 0.01); urine protein level, renal weight/body mass, area and volume of renal glomerulus in the irbesartan group were significantly lower compared to the DN group (P ＜ 0.01). ② By the 16th week,VEGF and Flk-1 expressions in the DN group were significantly up-regulated compared to control group (P ＜ 0.05); while,VEGF and Flk-1 expressions in the irbesartan group were also up-regulated compared to the control group by the 16th week (P ＜ 0.05) but down-regulated compared to the DN group (P ＜ 0.05). ③ VEGF staining in the DN group was darker compared to control group (P ＜ 0.01), while the staining in the irbesartan group was also darker compared to the control group (P ＜0.01), but the staining in the irbesartan group was lighter compared to the DN group (P ＜ 0.01). Flk-1 staining was similar to the VEGF. ④ VEGF and Flk-1 were positively correlated, with urine protein level, area and volume of renal glomerulus (P ＜0.05).CONCLUSION: VEGF and its Flk-1 receptor play important roles in DN pathogenesis. Over expressions may cause renal injury, but irbesartan (angiotensin Ⅱ receptor antagonist) has the protective effects on kidney through inhibiting abnormal expression of VEGF and Flk-1.

Objective To observe the expression of bone matrix proteins and the change of intima-tunica media thickness ratio in diabetic rat small renal artery and to explore their correlation and effects on diabetic nephropathy. Methods Seventy healthy SD rats were randomly divided into diabetic group(DN,n=40)and normal control group(N,n=30).DN rat model was induced by streptozotocin(STZ)intraperitoneal injection and the N group rats were given the same dose of citrate buffer.Thirty-five rats were successfully induced in DN group.The rats were sacrificed at week 4,12 and 24,respectively.The protein and mRNA expression of core-bind factor alpha 1(Cbfcd).bone morphogenetic protein 2(BMP-2)and matrix Gla protein(MGP)in smallrenal artery were detected by immunohistochemistry,in-situ hybridization and real-time PCR at each time point. Results Cbfctl and BMP-2 were expressed obviously in small renal artery of DN group by immunohistochemistry stain and in-situ hybridization from 4 to 24 weeks compared with N group at each time point,reaching the peak at week 24.Real-time PCR showed that the MGP mRNA was evidently increased at week 4,slightly decreased at week 12,lowest at week 24in DN group.The BMP-2 mRNA began to increase from week 4 onward,being peak at week 24in DN group.The ratio of intima to tunica media thickness had no significant difference in DN group compared with N group at week 4,but at week 12 and 24 there were significant difference between them.There was a positive correlation between Cbfα1 and BMP-2 expression,but they were negatively correlated with the expression of MGP.The ratio of intima to tunica media thickness was significantly-correlated with the expression of Cbfα1 and BMP-2. Conclusions The ratio of intima to tunica media thickness is positively correlated with Cbfα1 and BMP-2 in small renal artery of early DN.Cbfα1,BMP-2 and MGP may be involved in the progression of vascular lesions in DN.

Objective To investigate the clinicopathological features, immunophenotyping and clinical biological behavior of bone marrow (BM) involvement of systemic anaplastic large-cell lymphoma (S-ALCL).Methods 34 S-ALCL including 24 ALK(+) and 10 ALK(-) cases available with the formalin-fixed, paraffin embedded (FFPE) tissue blocks of BM biopsy (n=19) or BM smear sections (n=15) were included in this study.BM samples were sent to both morphologic evaluation using H&E (Hematoxylin & Eosin)-stained sections and immunophenotypic detection by immunohistochemistry (IHC). EBV status was determined by visualization of EBERs in tumor cells using in situ hybridization (ISH). Results BM involvement was seen in 17.6 % (6/34)S-ALCL patients which were confirmed by BM biopsy. No significant difference in the incidence of BM involvement was observed between ALK(+)[16.7 % (4/24)] and ALK(-) [20.0 % (2/10) S-ALCL (P =0.3555).Age and gender were not associated with the presence or the absence of BM involvement by S-ALCL (P= 0.8089and 0.3085), tumor cells of patients with BM involvement were interstitial distribution. S-ALCL patients with BM involvement have a poor prognosis as compared to those without BM involvement (P =0.0407). Conclusion BM involvement was not frequently seen in S-ALCL. The occurrence of BM involvement by S-ALCL was not associated with age, gender or the expression of ALK protein. BM involvement is an adverse prognostic factor in S-ALCL, BM biopsy is useful to predict the prognosis of S-ALCL.
