Objective To investigate the potential relationship between initial 131Ⅰ uptake by lung metastases from differentiated thyroid cancer (DTC) and treatment outcomes. Methods From 1997 to 2009, 41 patients with DTC lung metastases were treated in the authors' department. 131Ⅰ whole body scan (WBS), serum Tg levels and other imaging results were analyzed to evaluate the therapeutic effects. Complete response (CR) or partial response (PR) was considered to be effective. The x2 test and correlation analysis were performed using SPSS 11.5 software package. Results 131 Ⅰ treatment was effective in 63% (26/41) patients with DTC lung metastases, CR in 8 patients and PR in 18 patients. In other 37% ( 15/41 ) patients, 131Ⅰ treatment was ineffective, including one case died of distant metastases. Patients with initial presence of 131Ⅰ lung uptake had higher effective rate than those with 131Ⅰ lung uptake during the second or later 131Ⅰ treatment (76% (22/29)vs33% (4/12),x2 =4.911, P=0.027). Also, significantly higher effective rate was found in patients with lung metastases alone than those with extra-pulmonary metastases (75% (24/32) vs 22% (2/9), x2 = 6. 312, P =0.012). However, the effective rate in patients with diffuse metastases was not significantly different from that in patients with focal metastases (67% (12/18)vs 61% ( 14/23), x2 =0. 146, P=0.702). The positive rate of initial 131Ⅰ uptake by lung metastases was higher in patients with total thyroidectomy than those with partial thyroidectomy (83% (24/29) vs 42% (5/12) ). Those positive rates in patients with papilary DTC and patients with follicular DTC were 72% (23/32) and 6/9, respectively. The surgical mode was correlated with the initial 131Ⅰ uptake by lung metastases (r = 0.411, P < 0.05), but no correlation was found between the histological type and the initial 131Ⅰ uptake by lung metastases ( r = 0. 047, P > 0.05 ). Conclusion Initial uptake of 131 Ⅰ by lung metastases alone is a favorable prognostic factor for DTC patients treated by131Ⅰ, and total thyroidectomy may be beneficial for initial 131Ⅰ uptake by lung metastases.

Hepatic sclerosing hemangioma (HSH) is a rare benign tumor that is considered fibrosis and hyaline change caused by degenerative changes of cavernous angioma, and changes in pathological features cause the changes in imaging features, making this atypical hemangioma easily misdiagnosed as primary or metastatic malignant tumor. Although there are many studies on the imaging findings of this disease, it is still difficult to diagnose and most patients underwent resection since it is misdiagnosed as malignant tumor. There is still a low rate of confirmed diagnosis before surgery. This article elaborates on the etiology, clinical manifestations and pathological features, imaging findings, diagnosis, and treatment of HSH, in order to provide a reference for the diagnosis and treatment of this disease.

OBJECTIVETo evaluate the effect of importing triamcinolone acetonide into hypertrophic scars with skin roller needles.
METHODSThirty-two cases with burn hypertrophic scar were treated. The skin roller needles were moved back and forth on the hypertrophic scars with triamcinolone acetonide dropping on the scar surface at the same time. So the triamcinolone acetonide could be imported into the scar through needles and needle holes. The effect was evaluated as cured, effective, and no effect. The Vancouver scaring criteria and visual analogue scale was used to assess the scar color, thickness, texture and feeling before and after treatment, as well as at the untreated scar area (control).
RESULTSThirty-two cases were treated 1-3 times, including 28 cases with cured result and 4 cases with effective result. The total effective rate was 100%. The scar color, thickness, texture and feeling was significantly different between the scar before and after treatment, or between the treated and untreated scar (P < 0.05).
CONCLUSIONSImporting triamcinolone acetonide into hypertrophic scars with skin roller needles is effective. It is a new method for the treatment of large hypertrophic scar with medicine.

OBJECTIVETo investigate the effects of caspase-3 siRNA on the neurobehavior of mice exposed to aluminum.
METHODSMale KunMing mice (3 months old) were randomly divided into 4 groups by weight:blank control group (4 microl normal saline), Al group (4 microl 0.5% AlCl3), Al plus empty vector group(3 microl 0.5% AlCl3 plus control siRNA expression vector)and Al plus RNAi group (3 microl 0.5% AlCl3 plus targeted siRNA expression vector). All groups were treated by lateral cerebral ventricle micro-injection for 5 days. The neurobehavior was tested by the Morris water maze test, Open-field and Step-down tests for all treated mice. Pathological changes in hippocampus was observed by electron microscopy, the caspase-3 gene expression levels were detected using RT-PCR.
RESULTSThe results of Step-down test indicated that as compared with control group, the latent time [LT, (44.67 +/- 10.60) s] in A1 group decreased significantly, the error number (3.63 +/- 0.52) in Al group increased significantly and the LT [(68.00 +/- 14.70) s] in Al plus empty vector group decreased significantly (P<0.05). the LT [(239.50 +/- 19.36) s] in Al plus RNAi group increased significantly and the error number in Al plus RNAi group decreased significantly, as compared with Al group (P<0.05). The results of Morris water maze test showed that as compared with control group, the LT in Al group increased significantly, and residence time in the former platform quadrant decreased significantly and the LT in Al plus empty vector group increased significantly (P<0.05). The LT in Al plus RNAi group was significantly longer than that in Al group (P<0.05). The results of open-field test demonstrated that as compared with control group, the time in the central grid in Al group and Al plus empty vector group increased significantly, the rearing number and the modification number in Al group and Al plus empty vector group decreased significantly (P< 0.05). As compared with Al group, the time in the central grid in Al plus RNAi group decreased, the inter-cell number, the rearing number and the modification number increased significantly (P<0.05). The results of electron microscopic examination exhibited that a slight change of hippocampal cells appeared in control group, the obvious pathological changes of hippocampal cells appeared in Al group and Al plus empty vector group, but the pathological changes of hippocampal cells in Al plus RNAi group significantly reduced as compared with Al group. The results of thionin staining indicated that the layers of neural cells of hippocampal CA3 were more clear and there was not obvious denatured injury of neural cells of hippocampal CA3 in control group. The number and Nissl body color of neural cells of hippocampal CA3 in Al group and Al plus empty vector group decreased significantly. After RNA interference, the number and Nissl body color of neural cells of hippocampal CA3 increased obviously. The expression levels of caspase-3 gene in Al group and Al plus empty vector group were 2.24 +/- 0.57 and 2.28 +/- 0.33, respectively, which were significantly higher than that (1.00 +/- 0.00) in control group (P<0.05). The expression level of caspase-3 gene in Al plus RNAi group was 0.44 +/- 0.08, which was significantly lower than those in Al group and control group (P<0.05).
CONCLUSIONAluminum can decrease the learning and memorizing ability, and inhibited the activity or exploration function of mice. It is suggested that Caspase-3 siRNA may reduce the neurotoxicity induced by aluminum to a certain extent.

OBJECTIVESTo investigate the prognostic significance of Omi/HtrA2 expression, and the correlation between Omi/HtrA2 and Hypoxia-inducible factor (HIF)-1α in primary hepatocellular carcinoma cells.
METHODSThe expression of HIF-1α and Omi/HtrA2 in 43 cases of hepatic carcinoma tissues were detected immunohistochemically. Follow-up data were obtained to perform the Kaplan-Meier survival analysis. The change of Omi/HtrA2 expression in HepG2 cell was measured after HIF-1α expression of HepG2 in vitro was regulated by Tet-on expression system.
RESULTSOmi/HtrA2 expression was correlated with lymph node metastasis and recurring within liver during 2 years. Statistical analysis estimation showed the cumulative survival rate of post-hepatectomy for the patients with the positive expression of Omi/HtrA2 was higher than that for other patients with the negative expression of Omi/HtrA2 (χ(2) = 6.13, P = 0.013). In the common paraffin-embedded specimen of hepatocellular carcinoma, most of the samples showing negative or weak positive HIF-1α immunopositivity showed moderate positive or strong positive Omi/HtrA2 immunopositivity, while most of the samples showing moderate positive or strong positive HIF-1α immunopositivity showed negative or weak positive Omi/HtrA2 immunopositivity. The mRNA expression intensity of Omi/HtrA2 was decreasing with the HIF-1α expression increasing, and the difference was statistically significant(F = 106.766, P < 0.01).
CONCLUSIONSOmi/HtrA2 may be an important prognostic marker for primary hepatocellular carcinoma. Omi/HtrA2 expression is reversely correlated with HIF-1α expression in hepatocellular carcinoma. During the apoptotic process Omi/HtrA2 participating in hepatocellular carcinoma cells, HIF-1α is involved in the controlling and regulating of Omi/HtrA2 expression.
