Objective To evaluate the preliminary outcome of stable vitiligo treatment with ReCell(R )technique.Methods Six patients with stable vitiligo were treated with ReCell(R ) technique.In each patient,a thin razor-thickness cutaneous biopsy was harvested from uninvolved area near the vitiligo patches.It was then processed through the ReCell(R ) system and 1 ml autologous epidermal cell suspension was obtained.The lesion area was dermabraded using a diamond fraise wheel to the dermoepidermal junction.The cell suspension was then sprayed on the wound and covered with non-adhering dressings.Results The patients were followed up for 6 months.5 patients presented with repigmentaion in the treated area.There was no significant response in one patient who was diagnosed as systematic vitiligo.Conclusions The ReCell(R ) technique is an alternative treatment for stable vitiligo patients.The clinical outcome will be satisfactory when appropriate patients are selected.

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.
