The papers regarding moxibustion published in science citation index (SCI) journals for the recent 5 years were searched to explore the international tendency of moxibustion researches, which provided references for moxibustion to have a better internationalization. With methods of internet search and database search, a total of 116 papers regarding moxibustion were included. These papers were published in 40 kinds of journals, mostly in Britain and the United States. The journal with the highest impact factor was Stroke, which had 5729 points. The number and impact factor of these journals were inferior to those of acupuncture journal. Compared among these journals, the depth and width of moxibustion research were increasing year by year. The category of diseases related with moxibustion is mainly digestive system diseases, motor system diseases and urinary-genital system diseases. The type of papers was characterized with clinical observation and mechanism research. Researches related with moxibustion included moxibustion dose and safety. It was believed that the international recognition of moxibustion effectiveness, standardization of moxibustion manipulation, standardization research, etc. were needed to be solved in the further.

OBJECTIVETo explore the role of the basic fibroblast growth factor (bFGF) in the directional differentiation of bone marrow mesenchymal stem cells (BMSCs) into Leydig cells.

METHODSAfter purification and identification, we inoculated the third-generation BMSCs of SD rats onto a six-orifice board and then randomly divided them into groups A (normal saline control), B (human chorionic gonadotropin [hCG] + platelet-derived growth factor [PDGF] induction), C (hCG + PDGF + 5.0 ng/ml bFGF induction), D (hCG + PDGF + 10.0 ng/ml bFGF induction), and E (hCG + PDGF + 20.0 ng/ml bFGF induction). On the 7th, 14th and 21st day of induction, we observed the morphological changes of the cells and measured the level of testosterone (T) and expression of 3 beta hydroxy steroid dehydrogenase (3β-HSD) in the supernatant by immunofluorescence staining.

RESULTSAfter induction, the BMSCs of groups B, C, D, and E exhibited microscopic features of enlarged size, inter-connection, long-shuttle or irregular shape, adherent growth, and large round nuclei, all characteristic of Leydig cells. With the prolonging of time and enhanced concentration of bFGF, gradual increases were observed in the T level and the count of 3β-HSD-positive BMSCs in the four induction groups, with statistically significant differences between group B and groups C, D, and E (P < 0.05), as well as between group C and groups D and E (P < 0.05), but not between D and E (P > 0.05).

CONCLUSIONThe bFGF has an obvious promoting effect in the in vitro induced differentiation of rat BMSCs into Leydig cells.

Objective To investigate the value of 99Tcm-methoxyisobutylisonitrile (MIBI) scintigraphy in assessing the preoperative chemotherapy response and multidrug resistance of osteosarcoma.Methods From January 2007 to October 2008, 12 patients (female:4, male:8; mean age:16.3 years,range:8-27 years) underwent early (10min) and delayed (120 min) 99Tcm-MIBI scintigraphy before and after preoperative chemotherapy.Seven cases had osteosarcoma at the distal femurs, 2 at the proximal tibias, 2 at the upper end of humerus and 1 at the fibula.The tumor-to-background ratio (T/B) and washout rate (WR) were calculated.Tumor necrosis was classified according to Huvos criterion after limb salvage surgery.Immunohistochemical staining for P-glycoprotein(gp) was examined.Spearman correlation analysis and t-test were performed.Results According to Huvos criterion, 7 patients were classified as good responders with more than 90% of tumor cell necrosis and 5 as poor responders with less than 90% of tumor cell necrosis.R value (ratio of early phase T/B after and before chemotherapy) was significantly lower in good responders than that in poor responders (0.473 ± 0.21 vs 0.998 ± 0.06, t= 5.342, P= 0.000 ).R value was significantly correlated with the degree of tumor cell necrosis ( rs=- 0.87, P= 0.000 ).WR was significantly higher in patients with positive P-gp expression than that in patients with negative P-gp expression ((38.36 ±18.64)% vs (6.40±5.87)%, t= -3.278, P=0.008).There was significant correlation between the WR and P-gp expression (rs = 0.91, P= 0.001 ).Conclusion 99Tcm-MIBI scintigraphy is a feasible non-invasive technique to assess the chemotherapy response and to detect P-gp expression of osteosarcoma.

Detection of serum tumor markers in clinical application is simple,which has become an in dispensable means in clinical medical work,and played an important role in the early detection of malignant tumor,benign and malignant tumor differential diagnosis,guiding the stage and predicting prognosis.But because of its sensitivity and specificity have limitations,we should find more new markers.
