Objective To build three-dimensional model of the pancreas and peripanercatic organs to provide morphological basis for imaging diagnosis and operation selection of pancreas diseases. Methods Serial cross-sectional images from the first Chinese visible human dataset were reviewed and the structures of pancreas and peripancreatic organs were reconstructed three-dimensionally by using 3D-Doctor software on PC. Results Three-dimensional structures of pancreas and peripancreatic organs were reconstructed successfully. All reconstructed structures could be displayed in multiple methods and color modes. Conclusions The internal and adjacent struc-tures of pancreas can be clearly shown on the reconstructed three-dimensional images. The visible model is a useful reference both for clinical diagnosis and surgical practice.

Objective To establish the three-dimensional model of pancreas and its surrounding structures.Methods The three-dimensional pancreas model was established and analyzed by using PC computer platform based on the data set from the first Chinese visible human female.Results The three-dimensional pancreas model,established successfully,could be rotated at any angles and could be sectioned at any orientation.The structures of each section could be displayed clearly.Conclusion Sectional anatomy at any orientation of the pancreas and its surrounding structures can be performed on our pancreas model,which has laid the foundation for virtual surgery of the pancreas.

Objective To observe the effects of comprehensive measures of changing grain,selenium supplementation,off-site education and resettlement on prevention of children's Kashin-Beck disease in Aba state.Methods Fifty eight villages in Aba Kashin-Beck disease areas were chosen as intervention points in Aba state Sichuan province from 2007 to 2011.Based on the implementation of prevention and control measures,the villages were divided into off-site education + changing grain + selenium supplementation group and resettlement + off-site education + changing grain + selenium supplementation group,Geletuo town of Seda county,Ganzi state was selected as a control point,and right-hand anteroposterior X-ray examination(including the wrist) was carried out on children aged 6-13 from 2007 to 2011 annually.Clinical and X-ray diagnosis of Kashin-Beck disease was made in accordance with the Diagnostic Criteria of Kaschin-Beck Disease(GB 16003-1995).The effects of prevention and control measures were evaluated by comparing the child X-ray detection rate before and after the implementation of the measures.Results The average X-ray positive detectable rate of children in the intervention points was 2.07％(66/3181),2.72％ (69/2540),1.16％ (35/3017),0.56％ (19/3397) and 0.56％ (24/4273),respectively from 2007 to 2011,with a downward trend (x2trend =66.74,P ＜ 0.01).There was a downward trend in the average X-ray positive detectable rate of children in off-site education + changing grain + selenium supplementation group [1.60％(29/1809),2.63％ (39/1484),1.29％ (25/1941),0.64％ (15/2332),0.42％ (10/2379)] and resettlement + off-site education + changing grain + selenium supplementation group [2.70％ (37/1372),2.84％ (30/1056),0.93％(10/1076),0.38％ (4/1065),0.74％(14/1894)] (x2trend=30.97,35.19,all P ＜ 0.01).The average X-ray positive detectable rate of children in the intervention group was 0 from 2007 to 2010,and was 1.61％ (1/62) in 2011.The difference of X-ray positive detectable rate was not statistically significant in the control group in the 5 years from 2007 to 2011.The difference of children's X-ray positive detectable rate was not statistically significant between control group and intervention group.Conclusions The effect of taking changing grain,selenium supplementation,off-site education and resettlement comprehensive measures to prevent children's Kashin-Beck disease is not significant in those places where the state of Kaschin-Beck disease is not active.

BACKGROUND:The present study was performed to further improve our understanding of the molecular mechanisms involved in the activation of NFkB, a major transcriptional factor involved in the inflammatory response in the inflammatory response in the lung, by particulate matter in lung epithelial cells wit an aerodynamic diameter of less than 2.5 micro meter(PM2.5). METHODS: Immediate production of reactive oxygen species (ROS) and nitrogen species (RNS), with the PM2.5 induced expression of inducible nitric oxide synthase (iNOS), IkB degradatio and NFkB-dependent transcrptional activity, in A 549 cells, were monitored. Addition, we also examined the effect of the iNOS inhibitor, L-N6-(1-iminoethyl) lysine hydrochloride (L-NIL), on the PM 2.5-induced NFkB activation in A 549 cells. RESULTS:The rapid degradation of IkB and the increase of transcriptional activity of the NFkB-dependent promotor were observed in A 549 cells exposed to PM2.5. The immediate production of ROS in response to PM2.5 in A 549 cells was not clearly detected, although immediate responses were observed in RAW 264.7 cells. A549 cells, cultured in the presence of PM2.5, produced an increase in NO, which was noticeably significant after 15 min of exposure with the expression of iNOS mRNA. The addition of L-NIL, an iNOS inhibitor, significantly inhibited the PM2.5-induced IkB degradation and the increase of the NFkB-dependent transcriptional activity. CONCLUSION: These results suggest that PM2.5 stimulates the immediate production of RNS, leading to the activation of NFkB in the pulmonary epithelium.

OBJECTIVETo develop an approach to the determination of saponins in Radix Cynanchi Atrati, and to optimize the parameters for purified the preparation of total saponins by macroporous resin column chromatography.

METHODUsing cynanversicoside A as a reference, the determination of saponins was performed; according to the elution rate and the purity of the products, the preparation performance of total saponins by macroporous resin was investigated, and its parameters were optimized.

RESULTThe saponins in Radix Cynanchi Atrati were successfully determined at 518 nm by vanillin-perchloric acid as spray reagent. The macroporous resin HP-20 showed static absorption ratio of 59. 3 mg x g(-1); the 70% ethanol extraction of Radix Cynanchi Atrati was eluted from column of macroporous resin HP-20 by water and 30% ethanol, and the saponins were concentrated in 90% ethanol solution. The content of saponin part eluted from HP-20 column was 77.62%.

CONCLUSIONThe proposed approach allows convenient and efficient preparation and purification of saponin in Radix Cynanchi Atrati.

BACKGROUNDLenalidomide has emerged as an important treatment for patients with multiple myeloma (MM). However, its role in the management of MM is still controversial and requires further clarification. The aim of this study was to evaluate efficacy and safety of lenalidomide for MM using a meta-analysis.

METHODSWe searched the electronic databases including: PubMed, EMBASE and the Cochrane Center Register of Controlled Trials. Seven randomized clinical trials were identified, which included a total of 2357 patients with MM who received lenalidomide-containing, noncontaining lenalidomide regimens or placebo as induction therapy or maintenance therapy. The outcomes included overall response (OR) rate, complete response (CR) rate, 3-year progression-free survival (PFS) rate, 3-year overall survival (OS) rate, and different types of treatment-related adverse events. We calculated the risk ratios (RRs) as well as their 95% confidence intervals of these outcomes and pooled the results using RevMan 5.2 software.

RESULTSFor patients with previously untreated MM, OR rate and CR rate was significantly higher in lenalidomide-containing group than the control group. For relapsed or refractory MM patients, lenalidomide-containing regimens significantly improved the OR rate, CR rate, 3-year PFS rate and 3-year OS rate. With regard to MM patients after autologous stem cell transplantation, lenalidomide maintenance therapy significantly improved 3-year PFS rate but did not result in improved 3-year OS rate. In terms of toxicities, lenalidomide therapy has a higher rate of Grade 3-4 grade cytopenias, infection, deep-vein thrombosis, and diarrhea. Furthermore, the incidence of second primary malignancies was significantly higher in the lenalidomide group.

CONCLUSIONSThe lenalidomide-containing regimens as induction therapy clearly increased response rates and improved intervals of survival with acceptable toxicity rates for patients with MM. However, when physicians choose to use the lenalidomide as maintenance therapy, whether the benefits outweigh the risks should be taken into account.

OBJECTIVETo investigate the effect of iodine-125 implantation on immune cell subsets and cytokine production in patients undergoing hepatocellular carcinoma (HCC) resection.

METHODSSixty-eight patients with resectable HCC were randomly divided into intrahepatic iodine-125 embedding group and control group. The percentages of T lymphocyte phenotypes (CD3(+), CD4(+), CD8(+)), NK cells, and the plasma concentrations of IL-4, IL-10, IL-12 and IFN-gamma of the patients were determined with flow cytometry and ELISA, respectively.

RESULTSIn the control group, the postoperative CD3(+) and CD4(+) immunocytes were (39.38-/+6.98)% and (24.34-/+3.18)%, significantly lower than the preoperative levels [(62.58-/+8.67)% and (30.63-/+4.19)%, respectively, P<0.05)]. The postoperative concentrations of IL-4 and IL-10 were (29.83-/+7.99) and (87.54-/+2.89) ng/L, significantly higher than the preoperative levels (10.35-/+8.76 and 64.25-/+2.54 ng/L, respectively, P<0.05). In the treatment group, the percentages of the immunocytes and cytokine concentrations underwent no significant changes after the operation, but postoperative IL-12 (89.46-/+11.43 ng/L) and IFN-gamma (47.78-/+5.45 ng/L) levels were significantly higher than the preoperative levels (36.13-/+9.16 and 7.14-/+2.17 ng/L, respectively, P<0.05). Significant differences were found between the two groups in the postoperative CD3(+) and CD4(+) immunocytes and IL-4, IL-10, IL-12 and IFN-gamma levels.

CONCLUSIONIodine-125 implantation can strongly stimulates the anti-tumor immune response in HCC patients by increasing CD3(+) and CD4(+) immunocytes and promoting Th2/Th1 deviation.
