Objective: To assess fluid-attenuated inversion recovery (FLAIR) vascular hyper-intensity (FVH) and explore its relationship with CT perfusion (CTP) penumbral/infarct core mismatch ratio and diffusion weighted imaging (DWI) final infarct volume in acute ischemic stroke (AIS) patients with middle cerebral artery occlusion (MCAO). Methods: The CTP and MRI images of 38 AIS patients with MCAO were reviewed. The FVH score (longitudinal direction) [FVH score (L)] and FVH score (transverse direction) [FVH score (T)] were quantified on the FLAIR images. The FVH score (L) (range, 0-16) was based on a rostrocaudal extension of FVH and the FVH score (T) (range, 0-3) was based on FVH supply of the occluded MCA territory. The mismatch ratio was calculated from the ratio of the [mean transit time - cerebral blood volume (CBV)] lesion/CBV lesion on the CTP images. The DWI infarct volume was measured on the DWI images. Results: The mismatch ratio was larger for the group of FVH score (L)=7~8 than those of FVH score (L)=5~6 and FVH score (L)=3~4 (p=0.03), whereas the DWI infarct volume was smaller (p=0.04). Similarly, the mismatch ratio of FVH score (T)=2~3 group was larger than FVH score (T)=1 group (p=0.01), whereas the DWI infarct volume was smaller (p=0.02). Both FVH score (L) and FVH score (T) correlated positively with mismatch ratio (P=0.02, P=0.001, respectively), but negatively with DWI infarct volume (P=0.03, P=0.004, respectively). Conclusions: Higher FVH score is associated with larger mismatch ratio and smaller DWI infarct volume in AIS patients with MCAO. FLAIR vascular hyperintensity may represent collateral arterial circulation, and may play a role in protecting the ischemic penumbra.

OBJECTIVETo review and investigate the optimal preoperative diagnostic means and treatment principles of hepatic angiomyolipoma (HAML).

METHODSThe clinical features, treatment, prognostic and follow-up data of 169 HAML patients treated between January 1992 and May 2010 were retrospectively analyzed. The median age of the patients, including 46 male and 123 female (male/female, 1/2.7), was 45 years (range, 17 - 73 years). The mean case history was 0.54 year with a range of 2 d to 16 years.

RESULTSAmong the 169 patients, 149 patients (88.2%) had a solitary tumor and 96 patients (56.8%) were detected in the right lobe. The overall preoperative diagnostic rate was 13.6% and 119 patients (70.4%) were misdiagnosed as hepatocellular carcinoma or hepatic cavernous hemangioma. The diagnostic accuracy of MRI is higher than CT in distinguishing the nature of the tumor (χ² = 5.508, P = 0.019). One hundred and sixty-eight patients received surgical resection and one received percutaneous microwave coagulation therapy. One patient occurred postoperative hemorrhage and 3 patients developed hydrothorax. The postoperative mortality and recurrence for all the patients were 0. Postoperative pathology confirmed the diagnosis of hepatic angiomyolipoma. Follow-up study showed a benign course and no signs of recurrence.

CONCLUSIONSMRI is the main diagnostic means of HAML. Treatment strategies of HAML depends largely on tumor size, location and growth rate. Surgical management is suggested to patients with the following criteria: (1) tumor size greater than 5 cm; (2) with clinical symptoms; (3) faster tumor growth; (4) the tumor located at 1, 4, 5, 8 segments of liver.

OBJECTIVETo investigate the expression of D2-40 and CD34 in invasive ductal carcinoma of the breast and the clinical significance.

METHODSD2-40 and CD34 expressions were detected immunohistochemically in 108 cases of invasive ductal carcinoma of the breast and 30 cases of breast fibroadenoma. The lymphatic microvessel density (LMD) and the microvessel density (MD), marked by D2-40 and CD34, respectively, were calculated and their relationship with the clinicopathological factors was analyzed.

RESULTSThe LMD and MD for invasive ductal carcinoma of the breast were significantly higher than those of breast fibroadenoma (P<0.01). One-way ANOVA indicated that the LMD differed significantly between tumors of different histological grades, status of lymph node metastasis and TNM stages; the MD also varied significantly with the tumor size, histological grade, lymph node metastasis and TNM stage. The LMD and MD showed a positive correlation to the tumor size (r=0.335, 0.337), histological grade (r=0.580, 0.671), lymph node metastasis (r=0.690, 0.721) and TNM stage (r=0.623, 0.634), but not to ER, PR or Her-2 status (P>0.05).

CONCLUSIONSD2-40 can specifically mark the lymphatic endothelial cells in invasive ductal carcinoma of the breast. The LMD and MD are positively correlated to the clinicopathological factors of the malignancy. D2-40 and CD34 has the potential for use as the predictors to evaluate the tumor progression and metastasis.

OBJECTIVETo investigate the feasibility of D2-40 labeling for detecting lymphatic vessels in breast cancer tissues and the clinicopathological implications of lymphatic vessel invasion (LVI).

METHODSImmunohistochemistry was used to detect the expression of D2-40 and lymphatic invasion in 72 cases of breast cancer and 15 benign breast tumor tissues, and their correlations to the clinicopathological factors were analyzed.

RESULTSThe positivity rate of LVI was 69.4% in breast cancer tissue. In patients with lymph node metastasis, the positivity rate of LVI was significantly higher than that in patients without lymph node involvement (85.7% vs 54.1%, P<0.01), and LVI was found to be positively correlated to axillary lymph node metastasis (r=0.382).

CONCLUSIOND2-40 can specially and reliably mark the lymphatic vessels in breast cancer tissues. LVI is positively correlated to axillary lymph node metastasis and occurs earlier than the latter, therefore should be included in routine clinicopathological testing.

OBJECTIVETo investigate the role of insulin receptor substrate 2 (IRS2) and Bax on mouse islet cell apoptosis in the presence of high glucose in vitro.

METHODSThe pancreatic islet cells were isolated from Kunming mice and divided into 6 groups (G1-G6 groups) for a 72-h culture in the media containing different concentrations of glucose (5.6, 7.8, 11.1, 16.7, 22.2, and 27.6 mmol/L, respectively). Insulin secretion by the cells was evaluated by radioimmunoassay, and the expressions of IRS2 and Bax were detected using immunocytochemistry and immunofluorescence assay, respectively. Hoechst33342 staining was employed to observe the cell apoptosis.

RESULTSExposure to 5.6-11.1 mmol/L glucose resulted in increased insulin secretion and progressive elevation of IRS2 and Bax expression, whereas the cell apoptosis underwent no obvious changes. In the presence of glucose above 16.7 mmol/L, the percentages of apoptotic islet cells increased with glucose concentration, but insulin secretion and IRS2 expression decreased; Bax expression significantly increased in the presence of high-concentration glucose.

CONCLUSIONProlonged exposure of mouse islet cells to high glucose induces apoptosis and impairs insulin secretion of the cells. Decreased IRS2 expression and increased Bax expression may play an important role in the glucotoxicity in mouse islet cells.

Objective To access the prevalence of type 2 diabetes mellitus ( T2DM) and its associated risk factors among adults with obesity in Zhejiang province. Methods The enrolled subjects were selected among local residents aged≥18 years with body mass index≥28 kg/m2 from 15 counties by multi stage stratified cluster random sampling from July to November, 2010. Each participant was required to attend complete questionnaire, physical examination, and testing overnight fasting blood specimen. Results A total of 1 351 residents were enrolled, including 613 males and 738 females. The prevalence of T2DM in adult population with obesity was 15. 03%, being 14. 03% in male, and 15. 85% in female;and that in urban area was 16. 64%, and in rural area was 13. 93%. Data from multivariable logistic regression showed that factors such as ageing (OR=1. 473, 95% CI 1. 243-1. 747), a family history of T2DM(OR=8. 945, 95% CI 5. 481-14. 598), staple food intake (OR=1. 185, 95% CI 1. 017-1. 380), triglyceride(≥1. 7 mmol/L, OR=1. 542, 95%CI 1. 066-2. 232) were risk factors of T2DM;while annual income(OR=0. 695, 95%CI 0. 544-0. 888), and milk intake(OR=0. 750, 95%CI 0. 567-0. 993) were shown as protective factors. Conclusion The prevalence of T2DM in adults with obesity was raised, ageing, a family history of T2DM, staple food intake, and dyslipidemia appeared to be major risk factors for T2DM.

This study was aimed to investigate the clinical value of quantification of AML1/ETO fusion transcripts using real-time reverse transcription PCR. Fourteen AML1/ETO positive children out of 52 AML children were selected. A serial dilution of AML1/ETO plasmid was used as a template for the AML1/ETO real-time PCR. AML1/ETO was quantified according to the expression of the GAPDH housekeeping gene at new diagnosis and during/after chemotherapy and transplantation. SPSS statistics was used to analyze the data. The results showed that the ratio of AML1/ETO: GAPDH expression level at new diagnosis varied in the range 0.219-2.080 (median 0.648) among the patients, without relevance with percentage of blasts. The detection sensitivity was up to the dilution of 1:10(5). Six patients showed a slight decline of AML1/ETO (higher than 5 x 10(-2)) at 1 month, three of whom relapsed in the early stage and one later. Five patients had a higher level than 5 x 10(-3) at 3 months, three of whom relapsed. Four patients with always a higher level than 5 x 10(-3) all relapsed in early stage. After six months, four out of them with constant low-level expression (10(-4) - 10(-6)) were in continuous complete hematological remission (CCR). In another patient, a rapid rise of AML1/ETO transcripts could be detected at CR stage and he relapsed 5 months later. The AML1/ETO gene expression leveling off by 10(-5) - 10(-6) could be detected in 3 patients at their complete remission after 9 months. It is concluded that real-time RT-PCR is a suitable approach for quantifying AML1/ETO transcripts in monitoring of AML patients with t(8;21) during/after chemotherapy and provides data of diagnostic relevance.
