In order to study the contraindications of the compatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae, in this study, the solubilizing and poisoning essence were explored. In this experiment, chromatographic assay, field emission scanning electron microscopy, MTT cytotoxicity evaluation, and other methods were used to study the main chemical components, morphology and toxicity of the ethyl acetate part of Flos Genkwa and its co-decoction with glycyrrhizic acid, in order to clarify Flos Genkwa-Radix et Rhizoma Glycyrrhizae incompatibility provides a new idea for the research on incompatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae. The results showed that after co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid, high performance liquid chromatography (HPLC) detected the dissolution of the toxic component yuanhuacine of 54.8%, while yuanhuacine chromatographic peak was not detected in the Flos Genkwa ethyl acetate part of the single decoction. The increase of co-decoction dissolution rate was observed by scanning electron microscopy, and it was found that glycyrrhizic acid uniformly dispersed the fat-soluble components of Flos Genkwa into nano-scale particles, which improved the solubility and stability in the solution. Furthermore, the results of cytotoxicity evaluation showed that the survival rate of cells decreased after co-decoction, 4',6-diamidino-2-phenylindole (DAPI) staining also gave the same results. In summary, the co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid promotes the dissolution of the toxic component yuanhuacine, and makes the part form uniformly distributed nanoparticles, which is conducive to the absorption of the ingredient and increases the toxicity.

BACKGROUNDRecurrent stroke following a transient ischemic attack or minor stroke is frequent but potentially preventable. The prevention outcome is, by and large, dependent on how well physicians understand and implement prevention guidelines. Yet, little is known about the scope of physicians' awareness and implementation of secondary stroke prevention guidelines in the mainland of China. This study aimed to identify the gaps between physicians' clinical practice and guidelines for secondary stroke prevention in China.
METHODSA nation-wide online survey with a 16-item questionnaire that reflects major components of the Chinese National Secondary Stroke Prevention Guidelines was performed between September 1, 2009 and October 31, 2009.
RESULTSA total of 3489 neurologists from third tier hospitals completed the survey. The percentage of the physicians who were aware of the control targets and prevention measures recommended in the Chinese national guidelines was generally lower than reported for developed countries.
CONCLUSIONSPhysicians in the mainland of China lack sufficient awareness of secondary stroke prevention guidelines. Continuing education is highly recommended.

OBJECTIVETo compare mini-probe endoscopic ultrasonography (MCUS) with computed tomography (CT) in preoperative T and N staging of esophageal cancer, and to find out the MCUS parameters to judge lymph node metastasis for esophageal cancer.
METHODSThirty-five patients received both MCUS and CT preoperatively, on both of which the T and N stages were determined. The accuracy, sensitivity, specificity, positive predicting value and negative predicting value were compared with the postoperative pathological results.
RESULTSThe accuracy of MCUS was 85.7% in T staging and 85.7% and 80.0% in N staging by the two different methods, which were 45.7% and 74.3%, respectively, by CT.
CONCLUSIONMCUS is better than CT in preoperative staging for esophageal cancer. The ratio of short to long axis (S/L) combined with short axis is a useful way to determine lymph node metastasis.

OBJECTIVETo assess the value of histologic examination, immunohistochemistry and gene rearrangement studies in the diagnosis and subtyping of lymphoma with bone marrow involvement (BMI).
METHODSSixty-two formalin fixed, paraffin embedded bone marrow biopsy specimens were studied. Immunohistochemical and immunoglobulin heavy chain (IgH) and T-cell receptor gene rearrangement studies were performed in each case.
RESULTSChronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) demonstrated mainly and interstitial infiltration by dysplastic lymphocytes, with intertrabecular nodular arrangement or in dispersion. Sometimes, pseudofollicles may be noted. A predominantly para- or intertrabecular infiltration by nodules of lymphoma cells was characteristic of follicle center cell lymphoma (FCL) cases. In most lymphoplasmacytoid lymphoma (LPL) cases, there was infiltration by small lymphocytes and plasma cells between bony trabeculae. In marginal zone cell lymphoma (MZL), vague inter- or para-trabecular nodules of polymorphic lymphoma cells with clear cytoplasm might be noted. Small to medium-sized dysplastic lymphocytes, with absence of paraimmunoblasts or pseudofollicles, were the most frequent findings in mantle cell lymphoma (MCL). Hairy cell leukemia (HCL) might be identified by the presence of distinct cell membrane and abundant clear cytoplasm, resulting in a "fried-egg" appearance. Tumor cells with large nuclei and eosinophilic nucleoli were characteristically seen in lymphomatosis diffusa (Hodgkin's disease, HD). In T-cell non-Hodgkin lymphoma with BMI, dispersed or clusters of intertrabecular neoplastic lymphoid cells with clear cytoplasm and gyriform nuclei were often observed. In diffuse large B-cell lymphoma (DLBL), the tumor cells were large and isolated or arranged in diffuse pattern. Immunohistochemically, a panel of markers, including CD3 CD20, and CD79 are valuable for the differential diagnosis of T- and B-cell lymphomas. The neoplastic cells in MCL were cyclin D1- and CD5-positive, while BCL2- and CD10-positivity was characteristic for FCL. CLL/SLL cells might be stained with CD5 and CD23, in addition to CD20 and CD79. CD25 expression might be noted in HCL: the positivity for CD15, CD30 and fascin suggests HD. There was a higher positivity rate for IgH gene rearrangement in CLL/SLL, LPL MZL and DLBL (80%, 60%, 66.7%, 70% respectively) and for T- cell receptor gamma gene rearrangement in T-cell lymphoma (66.7%).
CONCLUSIONA combination of histopathology, immunohistochemistry and IgH / T-cell receptor gamma gene rearrangement studies may be of aid to the diagnosis and subtyping of lymphoma with BMI, especially if there is only a small number of tumor cells present in the specimen.

AIM:To investigate the relationship between Sonic Hedgehog(Shh)signaling pathway and cell cycle and radioresistance of esophageal cancer by up-regulating Gli1,a key factor in Shh signaling pathway.METHODS:The human esophageal cancer cell line Eca 109 was transfected with plasmid to induce Gli 1 over-expression,which served as Eca109-ox-Gli1 group.In addition, Eca109 cells transfected with empty plasmid served as negative control group and the untreated Eca109 cells were used as normal control group.The expression of Gli1 was confirmed by real-time PCR and Western blot.The radiosensitivity of the cells in the 3 groups was determined by colony formation assay.The effect of irra-diation on the cell cycle was analyzed by flow cytometry.RESULTS:The expression of Gli1 in Eca109-ox-Gli1 group was higher than that in the other 2 groups(P<0.05).The survival fraction at dose of 2 Gy in Eca109-ox-Gli1 group was high-er than that in normal control group, indicating that the radioresistance of the Eca 109 cells transfected with Gli1 plasmid was increased.The cells in Eca109-ox-Gli1 group showed higher S phase proportion than that in normal control group and negative control group(P<0.01).After irradiation at dose of 6 Gy,all cells in the 3 groups found that the cell cycle was arrested at G2/M phase,while the cells in normal control group showed higher G 2/M phase proportion than that in Eca109-ox-Gli1 group(P<0.01).CONCLUSION: The up-regulation of Gli1 may enhance the radioresistance of esophageal cancer by regulating the cell cycle.
