Purpose To retrospectively analyze and summarize the image features of rare ovarian clear cell carcinoma (OCCC), and to provide basis for clinical diagnosis. Materials and Methods CT and MRI features of 30 cases of OCCC confirmed by pathology were retrospectively analyzed. Sixteen of all the patients underwent pre- and post-contrast CT scan. And 14 patients underwent pre- and post-contrast MRI scans. Results ① CT features: unilateral mass was revealed in 15 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 8 to 23.7 cm, mean (12.86±3.96) cm. One mass was irregular, 4 masses revealed incomplete capsule, and 4 masses had septa in the mass. CT value of cystic part of the mass was 20-30 HU, and which of solid part was 28-53 HU. On post-contrast CT images, the septa and solid component of the mass showed marked enhancement and delay enhancement, while the cystic component showed no enhancement. ② MRI features: Unilateral mass was revealed in 13 cases and bilateral mass was in 1 case. The maximum diameter of the mass ranged from 9.2 to 30.0 cm, mean (14.03±4.72) cm. One mass was irregular, 2 masses revealed incomplete capsule, and 2 masses had septa in the mass. The cystic component showed heterogenous signal intensity on T1WI, and high signal intensity on T2WI. There was no enhancement on post-contrast images. The solid component showed iso-intensity on T1WI, high signal intensity on T2WI, and diffused restricted on diffusion-weighted images. There was markedly enhancement on post-contrast images. ③ Blood supply of the tumor: In 8 cases, the branch of enlarged ipsilateral ovarian artery fed the tumors. In other 16 cases, the masses were surrounded by enlarged ipsilateral ovarian vein. Conclusion The characteristic CT and MRI features of OCCC include: a cystic solid mass with complete capsule; the solid component projects into the cavity, which could be hypervascular and marked enhanced.

Traditional mineral Chinese medicine is a characteristic part of Chinese medicine, in the development of traditional Chinese medicine has its unique role. With the development of science and technology and the increase of the medical level, traditional mineral medicine research is gradually thorough and wide-ranging. In recent years, traditional mineral Chinese medicine research mainly includes the physical properties of mineral medicine, structure, chemical composition, pharmacology and treatment mechanism research. The above several aspects of research in the mineral medicine has important practical and theoretical significance. The above several aspects of research status and the problems existing in the research were briefly summarized and reviewed in this paper, and its development were discussed, to provide reference for further studies in the future.

The way of "extracting-salting-chromatography" was used to purify the phycoerythrin and phycocyanin from Porphyra yezoensis in process scale-up.First,by comprehensive comparison of efficiency,the Sephadex G-25 was selected from four resins (Sephadex G-25、G-100、S-300 and CL-6B) as the best choice used in crude extract desalting of phycobiliprotein.Then the preparation process of phycobiliprotein was scaled-up with raw material(Porphyra yezoensis) increased from 1g to 20g,and finally to 400g.The results indicated that the yields of purified phycoerythrin and phycocyanin (absorption spectra purity above 3.2) increased during according to process scale-up,with 0.323% phycoerythrin and 0.148% phycocyanin obtained from 400g frozen Porphyra yezoensis blades respectively.It is no doubt that the process involved in the experiment is a potential way for large scale preparation of phycobiliproteins of high purity.

Objective To review the experience of modified sternal elevation in management of pectus excavatum deformities. Methods A retrospective study was carried out on 268 children with pectus excavatum deformities from January 2002 to December 2005.Of these patients,213 were boys and 55 were girls.Their age ranged from 2 to 16 years and 2 months[mean,(4.48?2.74) years)].Among then,69 cases were aged from 2 to 3 years,130 cases from 3 to 6 years and 69 cases over 6 years.268 patients with PE underwent modified sternal elevation and fixation with the home made stainless steel strut.The lung cysts,esophageal hatal hernia and congenital heart diseases were surgical treated simultaneously.Results There was no death postoperative.Postoperative compli- cations included pneumonia in 1 case,subcutaneous fluid in 2.the foUow-up period was 1-5 years.One patient was found having light notch in sternum.All patients had satisfactory results.In 165 cases stainless steel strut have been taken off postoperatively and no recurrence occurred.Conclusion The modified sternal elevation procedure for pectus excavatum results in an excellent cosmetic outcome.

Accumulated data have suggested that vasoactive intestinal polypeptide (VIP) and corresponding receptor (VIPR) are involved in the development of hematopoietic stem cells and liver growth. In the present study, radioimmunoassay, biomolecular interaction analysis and reverse transcriptation polymerase chain reaction were used to quantify VIP, VIPR and detect the subtype of VIPR in rat liver during development. VIP concentration of liver in fetal or neonatal rats was significantly lower than that of teens or adult rats (P<0.05). The binding capacities of VIPR in liver of immature rats were much greater than that of the adult rats (P<0.05). The tendency of change in VIP concentration was contrary to that of the binding capacity of VIPR in the liver of rats during development. VIPR-1 was expressed in rat liver in all phases of development. These results may be of benefit to the understanding of the mechanisms of liver growth and fetal liver hemopoiesis shift.

BACKGROUNDCardiovascular diseases, especially coronary artery disease (CAD), are major causes of death in industrialized countries. Elevated concentrations of plasma homocysteine (Hcy) have been associated with an increased risk of CAD. Increased plasma levels of chemokine, characterized by their ability to induce migration and activation of leukocytes, may contribute to the pathogenesis of CAD. This study was designed to investigate the changes of plasma Hcy, monocyte chemoattractant protein-1 (MCP-1) and oxidative stress markers in acute coronary syndrome patients.
METHODSA total of 149 subjects were divided into four groups: 50 patients with unstable angina, 30 patients with acute myocardial infarction, 20 coronary restenosis patients after percutaneous coronary intervention and 49 healthy control subjects. Plasma levels of Hcy, MCP-1, malondialdehyde and superoxide dismutase were measured.
RESULTSPlasma levels of Hcy and MCP-1 showed significant increases in unstable angina, acute myocardial infarction and restenosis patients compared with control subjects (P < 0.05, respectively). Plasma levels of malondialdehyde were significantly increased in unstable angina and acute myocardial infarction patients when compared with control subjects (P < 0.05, respectively). Plasma superoxide dismutase levels were significantly reduced in acute myocardial infarction patients when compared with control group (P < 0.01).
CONCLUSIONHcy might act as an atherogenic factor through promoting chemokine, reactive oxygen species and oxidized low density lipoprotein production and thereby convert a stable plaque into an unstable potentially occlusive lesion.

Objective To explore the activation and function of Janus protein-tyrosine kinase (JAK)/ signal transducer and activator of transcription (STAT1) signal transduction pathway in kidney,lung and brain of MRL/lpr mice.Methods MRL/lpr mice with systemic lupus erythematosus (SLE) were studied at the age of 12 weeks up.Non-SLE MRL/lpr mice were used as controls.We used phosphospecific antibodies to detect STAT1 activation in kidney,lung and brain by immunohistochemistry and Western blots.Gene expression of the STAT induced feedback inhibitors of cytokine signaling 1 (SOCS-1) was investigated by SYBR green I real-time reverse transcriptase polymerase chain reaction (PCR).Results Phosphorylation of STAT1 protein was markedly activated in these three organs,although renal and pulmonary STAT1 activation were much more evidently activated.SOCS-1 gene expression increased in all three organs,while renal SOCS-1 gene expres- sion increased less than lung and brain.Conclusion The activation of JAK/STATI signal transduction path- way may be pathogenic in the organ involvement and progression of SLE.The pathogenesis of lupus nephritis may also be associated with the down-regulation of SOCS-1 feedback inhibition.
