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 the effect of Suanzaoren Decoction on hippocampus, cortex BDNF and TrKB gene expression in depression model rats. Methods Depression rat models were established by social-isolated raise and chronic stress stimulation. Suanzaoren decoction was administrated to the models. RT-PCR was adopted to detect the expression of mRNA BDNF and TrKB genes. Results The mRNA expression of BDNF and TrKB in cortex of Suanzaoren decoction high dose group、medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580±0.012, 1.860±0.019)were all higher than the model group(0.032±0.008, 0.001±0.000), showing a significant difference among four groups (P<0.01), and the mRNA expression of BDNF and TrKB in hippocampus of Suanzaoren decoction high dose group, medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580± 0.012, 1.860±0.019)were higher than the model group (0.021±0.015, 0.125±0.013), there was a significant difference between four groups(P<0.01). Compared with the model group, the mRNA expression of low-dose group of Suanzaoren decoction in both cortex and hippocampus of BDNF and TrKB was not significantly different to the model group(P>0.05). Conclusion Suanzaoren decoction can increase the expression of BDNF and TrKB gene, promote neuronal proliferation, and resist depression.

Objective To explore the use of integrated two methods in vitro in prediction of eye irritation caused by cosmetics.Method Chorioallantoic membrane vascular assay ( CAMVA), bovine corneal opacity and permeability (BCOP) and Draize rabbit eye irritation test were used to determine the predictive potential of eye irritation of 60 kinds of cosmetics.Results CAMVA method was able to distinguish 41 non-irritant samples and 18 irritant samples.BCOP method was able to predict 35 non-irritant samples , 21 mild-moderate irritant samples and 4 severe irritant samples . Combination of CAMVA and BCOP methods could obviously improve the identification ability of irritation , and the classification consistency with Draize rabbit eye irritation testing reached 98.3%.Conclusions The integrated test strategy combined BCOP with CAMVA can be used to appropriately predict ocular irritation of cosmetics , with a prediction range covering non-irritant to severe irritant samples .

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.

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

The widespread availability of multi-detector spiral CT and its post processing techniques,and MRI,provide us with important tools to carry out anatomical studies on pancreaticobiliary maljunction (PBM).Determining the relationship between PBM and biliary diseases contributes not only to a better understanding of pathogenesis and pathological process of biliary diseases,but it also provides evidence for prophylactic treatment.The present study reviewed the definition,classification,pathological anatomy of PBM,relationship between PBM and pancreaticobiliary diseases,and clinical treatments of PBM.
