Objective This study was to explore a justifiable approach for the translation of traditional Chinese medicine (TCM) terms in the light of Skopos Theory and thus to provide references to the standardization of TCM terms.Methods By exploring the source and development of a TCM term Bi,we studied its connotation,compared available English versions and decided on the choice version.Results The word arthralgia,obstruction or impediment was found to be the most frequently used word in 12 recognized publications,more frequent than the transliteration of Bi.Conclusion It is suggested that an accurate and a complete understanding of TCM terms and English expressions are required prior to translating so that the faithfulness and accuracy of the translation are maintained for the sake of optimal approximation.

A 34-year-old male patient with suspected pheochromocytoma was referred to our department for paroxysmal hypertension. Pheochromocytoma was confirmed by very high plasma nor-metanephrine ( NMN ) and metanephrine ( MN ). Contrast CT of the adrenal disclosed a 3.0 cm x 3.0 cm mass in the left adrenal. 18 F-FDG-PET-CT showed high uptake only in the left adrenal. When the patient's blood pressure was well controlled with 4 mg/d doxazosin for 2 weeks, surgery was then performed under laparoscopy. A round solid left adrenal pheochromocytoma was resected. After surgery, plasma MN and NMN levels returned to normal, and the patient was free of clinical symptoms with normal blood pressure. This patient has been followed 3 years with normal blood pressure, MN, and NMN levels, without tumor recurrence shown hy adrenal CT.

BACKGROUND:Previous in vitro studies mainly focused on morphological and nerve marker aspects in the study of bone marrow mesenchymal stem cells (BMSCs)-derived neuron-like cells,but less focused on the olectrophysiological properties of neuron-like cells following differentiation.OBJECTIVE:To study the electrophysiological changes of differentiation from BMSCs into neuron-like cells after induction by brain-derived neurotrophic factor (BDNF)/basic fibroblast growth factor (bFGF)/alltrans-retinolc acid (AT-RA).DESIGN,TIME AND SETTING:The cytological comparative in vitro study was performed at the Department of Neural Cell Laboratory,Tianjin Huanhu Hospital and College of life Science of Nankai University from June 2005 to October 2007.MATERIALS:Totally 3 male Wistar rats (6-week old,weighing about 160 g) were used in this study.METHODS:BMSCs were cultured and purified by their characteristic of plastic adhesion in vitro,and then induced by BDNF,bFGF and AT-RA,and differentiate into neuron-like cells.Whole-cell patch damp technique was used to detect cell membrane current prior to and 3 days following induction.MAIN OUTCOME MEASURES:MSC phenotype was determined by flow cytometry.Cell morphology was observed under the inverted microscope before and after differentiation.Neuron specific enolase expression was assessed by immunocytochemistry.Whole-cell current results were measured.RESULTS:Flow cytometry results demonstrated that CD90 positive rate (99±3)%,CD31 (3.4±0.8)%,and CD34 (0.3±0.1)%.This indicated that these cells were undifferentiated stem cells,with purity of 95%.Undifferentiated MSCs under the optical microscope were mostly fiat cells with processes,similar to fibroblast-like cells.Neuron-like cells appeared 3 days following induction.Immunocytochemistry results showed that MSCs before induction were weakly positive for neuron specific enolase,but strongly positive for neuron specific enolase.At 72 hours,the differentiated rate was (24.01±3.76)%.The peak currents of outward currents in neuron-like cells were significantly higher in the induction group compared with the control group (P ＜ 0.05),but no inward Na~+ current was detected.CONCLUSION:(bFGF & BDNF)/AT-RA could induce the differentiation of MSCs into neuron-like cells.These cells showed the tendency to differentiate into mature neurons,though having no electrophysiological properties of mature neurons.

[Summary] A 61-year-old female patient was diagnosed as ACTH independent Cushing′ syndrome, right adrenal adenoma, right facial infection. The situation was well controlled with antibacterial agents, abscess incision drainage and ketoconazole therapy. The patient received partial adrenolectomy of her right adrenal gland 16 months later. This case indicated that anti-adrenal agents could be a reasonable choice when the Cushing′syndrome patients were acompanied with severe infection.

OJECTIVE To investigate the preventive effect of Fengliao extract on ulcerative colitis of mice. METHODS Using the intestinal propulsion rate experiment and senna induced diarrhea model , the intestinal propulsion rate, diarrhea rate and index of diarrhea were observed. Mice were randomly divided into normal group,model group,mesalazine hydrochloride group and Fengliao extract 11.7, 23.4 and 46.8 g · kg-1 group. The mouse colitis model was induced by 4% dextran sulfate sodium. The mice were administraed once daily for 7 d while the disease activity index(DAI)score was calculated and the activity of tumor necrosis factor α(TNF-α),interleukin-1β(IL-1β), myeloperoxidase(MPO) and content of malondialdehyde(MDA) and nitric monoxide (NO) in colon tissue were determined. RESULTS Fengliao extract 46.8 g · kg-1 inhibited the intestinal propulsion rate(P<0.05),reduced the frequency of diarrhea and the diarrhea index(P<0.05). Results of colitis showed that the body mass of mice in the model group was significantly decreased but the DAI score increased compared with normal group(P<0.05). The activity of MPO and the contents of IL-1β,TNF-α,MDA and NO in colon mucosa were increased(P<0.01). Compared with the model group,Fengliao extract 46.8 g·kg-1 decreased the DAI score(P<0.05)while Fengliao extract 46.8 and 23.4 g · kg-1 reduced MPO activity in colonic mucosa and content of IL-1β,TNF-α,MDA and NO in colonic homogenate(P<0.05). CONCLUSION Fengliao extract can significantly improve the DSS induced colitis in mice,which is probably associated with its antispasmodic and anti-diarrheal effect as well as the reduced release of inflammatory mediators and antioxidants.

With the current accumulation of metagenome data, it is possible to build an integrated platform for processing of rigorously selected metagenomic samples (also referred as "metagenomic communities" here) of interests. Any metagenomic samples could then be searched against this database to find the most similar sample(s). However, on one hand, current databases with a large number of metagenomic samples mostly serve as data repositories but not well annotated database, and only offer few functions for analysis. On the other hand, the few available methods to measure the similarity of metagenomic data could only compare a few pre-defined set of metagenome. It has long been intriguing scientists to effectively calculate similarities between microbial communities in a large repository, to examine how similar these samples are and to find the correlation of the meta-information of these samples. In this work we propose a novel system, Meta-Mesh, which includes a metagenomic database and its companion analysis platform that could systematically and efficiently analyze, compare and search similar metagenomic samples. In the database part, we have collected more than 7 000 high quality and well annotated metagenomic samples from the public domain and in-house facilities. The analysis platform supplies a list of online tools which could accept metagenomic samples, build taxonomical annotations, compare sample in multiple angle, and then search for similar samples against its database by a fast indexing strategy and scoring function. We also used case studies of "database search for identification" and "samples clustering based on similarity matrix" using human-associated habitat samples to demonstrate the performance of Meta-Mesh in metagenomic analysis. Therefore, Meta-Mesh would serve as a database and data analysis system to quickly parse and identify similar

BACKGROUND:Gastric cancer stem cels involved in the neoadjuvant chemotherapy and conventional treatment are closely associated with relapse of gastric cancer. However, this conclusion has not yet been confirmed.
OBJECTIVE:To investigate the effects of gastric cancer stem cels in tumor invasion and metastasis and its effect on angiogenesis ability.
METHODS:We prepared nude mouse models of gastric cancer to isolate and culture gastric cancer stem cels. Harvested gastric cancer stem cels were detected in cel scratch test, ring test, inhibition rate test, cel migration test and tumorigenicity test.
RESULTS AND CONCLUSION:After 7 days of culture, the cels exhibited adherent growth but a lack of regularity that most cels were in a tadpole shape. In the cel scratch test, the scratch width was significantly different at 0 and 24 hours (P < 0.05). Under an inverted microscope, the cels were found to form a ring in the ring test. The 50% inhibiting concentration of gastric cancer stem cels induced by oxaliplatin was significantly lower than that induced by 5-fluorouracil (P < 0.05). The number of cels passing through the basilar membrane was significantly increased after cel migration (P < 0.05). After implantation of gastric cancer stem cels, the gastric tissue quality was significantly higher than that in normal nude mice of gastric cancer (P < 0.05). These findings indicate that gastric cancer stem cels responsible for tumor invasion and migration have stronger angiogenesis ability.
