Objective To analyze the etiology of duodenal trauma and improve the result of its diagnosis and treatment. Methods The data of 28 cases with duodenal trauma during March 1968 to September 2007 was analyzed retrospectively. Results Twenty-two (78.6%) patients had blunt injuries. The rate of duodenal trauma and associated injuries was 21.4%(6/28)and 89.3% (25/28) respectively. The easiest injury part on the deseending part constituting was 46.4% (13/28) ,the secondary on the horizontal part constituting was 21.4% (6/28).The postoperative complication rate was 28.6% (8/28), the mortality rate was 3.6% (1/28), and the cure rate was 96.4% (27/28). Conclusions The incidence of blunt injuries is high compared with other kinds of duodenal trauma in China. It suggests that the early diagnosis, exploration proper surgical management,and intensive postoperative care are emphasized to reduce the mortality and complication rate.

The endothelial-to-mesenchymal transition (EndMT) in endothelial cells contributes to the development of cardiac fibrosis,ultimately leading to cardiac remodeling.In this study,the effects and molecular mechanisms of celastrol (CEL) on transforming growth factor-β1 (TGF-β1)-induced EndMT in human umbilical vein endothelial (HUVEC-12) cells were investigated.The presented data demonstrated.that CEL significantly blocked the morphology change of HUVEC-12 cells induced by TGF-β1 without cell cytotoxicity.In accordance with these findings,CEL blocked TGF-β1-induced EndMT as evidenced by the inhibition of the mesenchymal markers,including collagen Ⅰ,Ⅲ,α-SMA,fibronectin mRNA expression,and the increase in the mRNA expression of endothelial cell marker CD31.These changes were also confirmed by double immunofluorescence staining of CD31 and vimentin.The in vitro scratch assay showed that CEL inhibited the migration capacity of the transitioned endothelial cells induced by TGF-β1.Further experiments showed that the beneficial effect of CEL on blocking the EndMT in HUVEC-12 cells was associated with the suppression of the TGF-β1/Smads signalling pathway,which was also confirmed by the inhibition of its downstream transcription factor snail1,twistl,twist2,ZEB1 and ZEB2.These results indicate that CEL blocks TGF-β1-induced EndMT through TGF-β1/Smads signalling pathway and suggest that it may be a feasible therapy for cardiac fibrosis diseases.

Objective To outline the research fronts of ten major sub-specialties in internal medicine.Methods Based on their impact factor scores and the proportion of the journals of 10 subspecialties (endocrinology & metabolism,cardiac & cardiovascular systems,hematology,infectious diseases,nephrology,gastroenterology & hepatology,respiratory system,rheumatology,critical care medicine,clinical neurology) in Journal Citation Report (JCR),and careful consulation of expert clinicians,we identified 50 journals.Their bibliographic records (including references) published in 2011 were downloaded,and the frequency of the references (citations) in each sub-specialty was counted and the highly cited records were extracted.We performed a clustering analysis according to the co-cited times among any pairs of the highly cited records.To tag each cluster of highly cited records,we browsed the titles and abstracts of all highly cited records in the same cluster,and concluded the main topics of each cluster.Finally,we extracted the current published papers devoted to particular cluster by some clustering analysis indicators.The clusters of highly cited records were considered as the intelligence base,and the main topics in current papers which citing these highly cited papers were considered as research fronts.Results Totally 50 journals on 10 sub-specialties in internal medicine were identified.A total of 202 highly cited papers,38 clusters (knowledge bases),and 152 corresponding current citing papers presenting the research fronts were selected.Conclusions We confirm and present research fronts in 10 major sub-specialties of internal medicine.This study provides a synchronic structure of contemporary research activities in internal medicine sub-specialties.

OBJECTIVETo explore the clinical efficacy and action mechanism of acupuncture for premature ovarian failure (POF).

METHODSAccording to prospective cohort study design, 30 cases were included. Based on theory of regulating Chong and Conception Vessels as well as soothing the liver and calming the nerves, acupuncture at Guanyuan (CV 4), Dahe (KI 12), Taixi (KI 3), Taichong (LR 3), Baihui (GV 20) was applied, three times per week and 3 months were considered as one session. Totally two sessions were performed. The menstruation condition, estradiol (E2), follicle-stimulating hormone (FSH) and scores of the clinical perimenopausal symptoms were taken as treatment outcomes.

RESULTSThe total effective rate was 86.7% (26/30) and the cured rate was 16.7% (5/30). The recovery rate of menstruation was 16.7% (5/30) and the regain rate of menstruation was 56.7% (17/30). After the treatment, the level of E2 was significantly increased from (45.41 +/- 18. 09) pmol/L to (59.07 +/- 24.21) pmol/L (P < 0.05), and the score of perimenopausal symptoms was obviously reduced from 14.28 +/- 8. 30 to 4.04 +/- 3.28 (P < 0.01). However, no statistical differences could be seen in FSH before and after treatment (P > 0.05).

OBJECTIVE: To establish 2-dimensional electrophoresis (2-DE) maps of Helicobac-ter pylori in human gastritis, and gastric cancer, to identify the differentially expressed proteins,and to discuss the role of bacterial factor in pathogenesis. METHODS: The total proteins of Helicobacter pylori in human gastritis and gastric cancer were separated by immobilized pH gradient-based 2-DE. The differentially expressed proteins were screened by PDQuest analysis software and identified by peptide mass fingerprint based on matrix-assisted laser desorption/ionization time of flight mass spectrometry, and searched on database. RESULTS: A well-resolved and reproducible 2-DE pattern of Helicobacter pylori was obtained from patients with human gastritis and gastric cancer. Fourteen differentially expressed proteins were identified, including proteins related to anti-oxidation,molecular chape-rones and detoxification, enzymes related to metabolism,proteins related to cytoarchitecture,and proteins related to signal conduction. CONCLUSION A well-resolved and reproducible 2-DE pattern of Helicobacter pylori in human gastritis and gastric cancer is established and differentially expressed proteins from these 2 diseases are identified. The differentiation of protein expression may play an important role in the pathogenesis of gastric cancer.
