OBJECTIVETo analyze the imaging features of osteopoikilosis and its diagnosis knowledge.

METHODSThe imaging data of 9 patients with osteopoikilosis were analyzed retrospectively, including 6 familial cases and 3 sporadic cases. In 6 familial cases,there were 4 males and 2 females with an average age of 28 years old ranging from 10 to 63 years. Clinical manifestations of 1 familial case were left knee pain and limitation of activity for 3 years, and other 5 cases without clinical manifestation. In 3 sporadic cases, there were 2 males and 1 female with an average age of 33.7 years old ranging from 25 to 44 years. Three sporadic cases had obvious injury history with following up from 6 to 12 months. All imaging results of 9 cases were observed.

RESULTSThe imaging data of 6 familial osteopoikilosis showed the multiple round or oval nodes within bone with clear margins, uniform density, different size. The occurrence of the hyperostotic spots preferentially localized in the epiphyses and metaphyses of the long bones, and carpus and tarus. X-ray features of 3 sporadic osteopoikilosis were similar to that of 6 familial cases and for 6 to 12 months follow-up X-ray features were unchanged.

CONCLUSIONThe imaging features of osteopoikilosis are relatively specific such as the multiple mottling dense focal within bone with clear border and bilateral symmetry, and the focus located on cancellous bone and the diaphyses usually is unaffected. The imaging is a valuable examination for the accurate diagnosis of osteopoikilosis.

Objective To investigate correlation between post-stroke depression (PSD) and multiple factors during onset of acute cerebral infarction. Methods Depression was measured with Hamilton Depression Rating Scales (HAMD) in 58 patients with acute cerebral infarction, and their neurological function were evaluated by neurological function defect (NFD) score. Their immunoglobulin G (IgG) index was calculated and level of nitric oxide (NO) in cerebrospinal fluid (CSF) was measured. Lesion and nature of cerebral infarction in 58 patients with acute stroke were located by CT. All the data were statistically analyzed with student-t test and ? 2 test, as well as linear regression model. Results Seventeen of 58 patients of stroke appeared PSD with an occurrence rate of 29.3%. Occurrence rate of PSD was significantly higher in patients with cerebral infarction than in those with cerebral hemorrhage  2=4.86, P

Transcatheter arterial chemoembolization (TACE) was the preferred method of non-operation treatment for hepatocellular carcinoma (HCC).Radical resection of HCC remains difficult,extrahepatic metastasis was not easy to deal with,and repeated treatment aggravated the liver injury,so the long-term efficacy was poor.Sorafenib could control tumor angiogenesis and block the proliferation of tumor cells.A male patient with primary HCC and in the stage Ⅱb according to the Chinese clinical liver cancer staging system was treated by TACE combined with sorafenib and antiviral treatment in Henan Cancer Hospital.After the treatment,the intrahepatic lesions were inactive,and the pulmonary metastasis was partially relieved.The patient was followed up till May 2012,and the survival time was 39 months.The hepatic function was normal,and the hepatitis B virus (HBV) replication was negative.No intervention treatmentrelated complications were detected,and the KPS score was 100.

Objective To value the significance of TGFBR2 gene in mediating HepG2 cell proliferation by RNA interference technology. Methods Three kinds of siRNAs targeting TGFBR2 gene were designed, synthesized and transfected into HepG2 cells via lipofetamine2000. Among three kinds of siRNAs, only the one with the most interference efficacy was selected and the correspondent DNA sequence was inserted into plasmid pEGFP-N3. Then the recombinant plasmid of siRNA-pEGFP-N3 was transfected into HepG2 cell and western blot was used to detect the protein level of TGFBR2. Then, TGF-β1 was used to stimulate HepG2 cells with or without siRNA interference and proliferation of HepG2 cells was observed. Results Among these three siRNAs, siRN-1 appeared to be the most effective. After stimulated by 5ng/mL TGF-β1, proliferation of HepG2 cells showed a marked increase in siRNA-1 group compared with blank and siRNA-NC groups (P<0.05). For all that, the proliferation rate was still lower than that in normal HepG2 cell group without TGF-β1 stimulation. Conclusion By silencing TGFBR2 gene, inhibition of TGF-β1 signaling pathway to HepG2 cells could be decreased, thereby enhancing the cell proliferation.

Human immunodeficiency virus (HIV) infection can cause variable movement disorders, including parkinsonism. HIV-related parkinsonism usually responds well to highly-active antiretroviral therapy (HAART), suggesting a possible reversible dysfunction of the dopaminergic system. We report the case of a 42-year-old man who presented with rapidly progressive symmetric parkinsonism, cognitive decline, and loss of postural reflex as the initial manifestation of HIV infection. A significant improvement of his parkinsonism after HAART demonstrates a potentially reversible dopaminergic system dysfunction secondary to HIV infection. A normal 99mTc-TRODAT-1 SPECT image after HAART treatment paralleled the clinical improvement in extrapyramidal symptoms. Early identification of HIV-related parkinsonism, especially in patients with symmetrical akinetic-rigidity and early loss of posture reflex, is important for its potential reversibility with HAART therapy.
