OBJECTIVETo investigate the correlation between enhanced computed tomography (CT) findings and pathological results of rare parotid gland tumors, and improve diagnosis accuracy.
METHODSThe enhanced CT manifestations of 22 cases with pathologically documented rare parotid gland tumors, which included 6 cases of basal cell tumor, 5 cases of myoepithelioma, 4 cases of vascular invasion, 3 cases of lymphatic cyst, 3 cases of lipoma, and 1 case of chondrosarcoma, were retrospectively analyzed. The location, size, shape, density, and relationship with surrounding structure were evaluated on CT images.
RESULTSThe enhanced CT showed that basal cell tumors occurred in the superficial lobe of the parotid gland, with clear boundary, within the cystic lesion. The lesions were moderate to obviously enhanced, which may be accompanied by enlarged lymph nodes. Myoepithelial tumors were located in the superficial lobe of the parotid gland, with a small cystic prone and microcalcification within a few cases. The lesions were moderate to obviously enhanced. Hemangiomas of soft tissue mass prominent in the parotid gland surface were mild to significantly enhanced. Larger lesions may occupy the entire parotid gland, with uneven density and visible vein stone. The CT density values of the lymphatic cyst were usually higher. Chondrosarcoma mainly manifested cystic mass at the calcification edge. Lipoma with fat density mass exhibited clear boundary without enhancement. Fiber separation could be observed in the lesion.
CONCLUSIONCT can reflect the pathological features of rare parotid gland tumors by demonstrating their corresponding imaging features. Enhanced CT is the most effective means of imaging to identify the nature of rare tumor of the parotid gland lesions.

OBJECTIVE:
To investigate the imaging manifestations of 16-slice enhanced CT of parotid adenolymphoma in the parotid gland and the corresponding pathology,in order to improve the understanding of the CT imaging manifestations of parotid adenolymphoma in the parotid gland.
METHOD:
The enhanced CT characteristics of 34 cases of parotid adenolymphoma in the parotid gland confirmed by histological pathology were retrospectively analyzed.
RESULT:
There were totally 86 lesions in 34 cases, of which 12 cases with lesions in bilateral sides and 22 cases with lesions in unilateral side. Sixty-six lesions located behind and below the superficial lobe of the parotid gland. The lesions showed moderate to obvious enhancement at arterial phase, and the cystic region within the lesions showed no enhancement.
CONCLUSION
The relatively specific enhanced MSCT manifestations of parotid adenolymphoma in parotid gland include lesions located behind and below the superficial lobe of parotid gland unilaterally or bilaterally, sometimes exhibited as multiple masses, with clear edge, obvious enhancement and cystic degeneration inside.

Aim To look for novel small-molecule inhibitors of CDK9 through structure-based virtual screening and biological activity determination.Methods Homology modeling of CDK9 was based on the 3-D structure of other cyclin-dependent kinase family members,and then virtual screening by DOCK(molecular docking)of database of small molecule was carried on.MTT method was used in inhibition of tumor cell growth in vitro,while Western blot was used for further study of molecular mechanisms.Results From the top 1000 compounds with the best DOCK energy score,27 compounds were selected for biological assay based on the diversity of chemical structure and functional group.12 of 27 selected compounds showed significantly inhibition activity on tumor cell proliferation,and only one compound in 12 with half-maximum inhibition concentration(IC50)values less than 20 ?mol?L-1 named C-21 was selected for further molecular mechanism study.The western blotting data showed C-21 compound could effectively inhibit CDK9 from phosphorylating large subunit C-terminal of RNA polymerase Ⅱ in a dose-dependent manner.Conclusions Through homology modeling,virtual screening by computer,determination of biological activity and experimental studies of molecular mechanism,a new promising lead compound targeted for CDK9 was found and confirmed.

OBJECTIVE:To explore an effective method to formulate management-related strategies for off-lable use of drugs by the evidence-based medicine. METHODS:The process of guideline formulation included seven procedures,i.g. establishment ofguideliesformulation workgroup;investigation and selection of the status quo on off-label drug use;identification of the clinical problems;retrieval and evaluation and comprehensing of evidence;applification of GRADE in evidence quality grading;formation of the recommendations consensus;peer review and result publication. And eventually guidelines were formed based on the steps. This study took off-label use of rheumatoid immunoprotective subjects as a case to explore. RESULTS & CONCLUSIONS:Based on the evidence evaluation system and above 7 steps,the methods and process of guideline formulation on off-label use of rheuma-toid immunoprotective subjects that integrated administration,law,clinical medicine,pharmacy subjects were made .The process of guideline formulation fully reflects multidisciplinary characteristics of the workgroup,the advanced nature of the process,the comprehensiveness of evidence ,the rigor of evidence quality grading,and the normalization of consensus. It provides reference in methodology for establishing a comprehensive evidence-based evaluation and management system of off-label use of drugs for all clinical specialist disease. Therefore,this scientific research results may promote the standardization and legalization of the off-label use of drugs management in China.
