Objective To investigate the role of O-linked N-acetylglutamine (O-GlcNAc) modification in glutamine-induced myocardial heat shock protein (HSP70) expression in a rat model of endotoxic shock. Methods Thirty-two 8 weeks old male SD rats weighing 250-300 g were randomly divided into 4 groups (n = 8 each):group Ⅰ control (group C); group Ⅱ LPS; group Ⅲ G+ LPS and group glutamine + LPS (group A + G + LPS). Endotoxic shock was induced by iv administration of LPS 10 mg/kg in group Ⅱ , Ⅲ and Ⅳ.Glutamine 0.75 g/kg was administered iv at 1 h before iv LPS in group Ⅲ and Ⅳ . Alloxan (an inhibitor ofO-linked N-acetylglucosamine transferase) 50 mg/kg was administered iv together with glutamine at 1 h before LPS in group Ⅳ. The animals were sacrificed at 6 h after iv LPS administration. Their hearts were removed for determination of the expression of O-GlcNAc and HSP70 in myocardium. Results Intravenous LPS significantly up-regulated the expression of O-GlcNAc and HSP70. Glutamine pretreatment further increased the expression of O-GlcNAc and HSP70. The glutamine pretreatment induced increase in O-GlcNAc and HSP70 expression was abolished by concomitant administration of alloxan. Conclusion O-GlcNAc modification may be involved in glutamine-induced myocardial HSP70 expression in endotoxic shock.

OBJECTIVETo evaluate the safety and effectiveness of Shengji Ointment (SO) (by external use) in treating infective ulcer patients with yang syndrome (YS).

METHODSA multicenter, stratified, randomized controlled clinical study was used in this study. A random digit table was formed in the ratio of 3:1,440 infective ulcer patients of YS from 5 centers were recruited, 330 in the treatment group (external use of SO, exchange once every 24 h) and 110 in the control group (external use of Votalin, exchange once every 24 h). The therapeutic course consisted of 21 days. The ulcer area, wound depth, pain degree were observed before treatment at day 3, 7, 14, and 21, and safety indices monitored at the same time.

RESULTSThe ulcer area was significantly reduced in the treatment group after 21-day medication, obviously superior to that of the control group (P = 0.002). Ulcer areas at different time points were analyzed. From the 7th day of medication the reduced area was obviously less in the treatment than in the control group (P = 0.002). Besides, the longer the more obvious difference. Compared with the control group, the healing rate of ulcer area, the pain disappearance rate, and the healing rate of ulcer depth were all obviously improved in the treatment group (all P < 0.01). No adverse event occurred in the two groups.

CONCLUSIONSExternal use of SO was safe and effective in treating infective ulcer patients with YS. It could accelerate wound healing with better analgesic effect.

BACKGROUND:Circulating fibrocytes originated from the peripheral blood are a fibroblast-like cel subpopulation of leukocytes. Circulating fibrocytes play an essential role in wound repair by secreting extracel ular matrix proteins and cytokines, initiating antigen-specific immunity, accelerating wound contraction as wel as promoting angiogenesis. However, the potential role for improving chronic wound healing and its mechanism is stil unclear. OBJECTIVE:To summarize the biological features of circulating fibrocytes and its potential role and mechanism in accelerating chronic wound healing. METHODS:A computer-based search of CNKI database from 2000 to 2014, PubMed database from 1994 to 2014 and Foreign Medical Journal Ful-Text Service database from 2000 to 2014 was performed using“circulating fibrocytes, non-healing wounds, diabetic foot ulcer, wound healing, cel therapy”in Chinese and English as the keywords to retrieve articles related to circulating fibrocytes, refractory mechanism of chronic wound healing and cel therapy for chronic wounds. Total y 54 articles meeting the inclusive criteria were included in result analysis. RESULTS AND CONCLUSION:Cel therapy with circulating fibrocytes is a safe and effective treatment for improving wound healing and has been used to repair various chronic wounds in the recent decades. Circulating fibrocytes are a distinct subpopulation of fibroblast-like leukocytes in the peripheral blood. It is able to migrate into wound sites at the early stage of wound repair and plays an active role in the wound healing process by secreting extracel ular matrix proteins, cytokines, presenting antigens, contracting wound and promoting neovascularization. Recently, it has been proved in animal experiments that circulating fibrocytes can accelerate chronic wound healing, especial y diabetic chronic wound.

Along with the frequent international communication of TCM, translation of related classics becomes increasingly important. The translation of TCM classics' titles, which reveal the content of the classics, is equally essential. Dictated by the translating principles of standardization, correspondence, readability and nationalism, the paper analyzed the translation of TCM classics' titles containing modesty words, and put forward the following translation strategies translation: The method of foreignization is preferred for the translation of titles involving heterogeneous culture in order to retain the unique TCM concept while the method of domestication is advised for the translation of titles involving elements in conflict with the target culture; In the translation of TCM classics' titles containing modesty word(s), weakening or omitting the sense of self-depreciation is proposed. The paper aimed to contribute to the standardization of TCM nomenclature translation in order to promote international dissemination of TCM classics.

Objective To investigate the relation between the expression of vascular endothelial growth factor (VEGF) and type Ⅳ collagen and the renal lesion of diabetes mellitus in diabetic rats. Methods Wistar rats were divided at random into normal control group(NC group) and diabetic model group(DM group), each group containing 20 animals. The rats models of diabetic mellitus were induced by streptozotocin(STZ). At the 8th week after induction, the expression levels of VEGF and type IV collagen in the kidney tissues in the two groups of rats were detected using immunohistochemistry. At the same time, the renal function of the rats was measured. Results At the 8th week,the expression levels of VEGF and type IV collagen of kidney tissues in DM group was much higher than those in NC group(P

To study the effect of intraarterial bolus of recombinant human angiogenin (rhANG) on stimulating revascularization in a rabbit hindlimb ischemic model,the limb ischemic model was induced by ligation and excision of every branches of the femoral artery in 28 rabbits. On the 11th day after operation, various doses of rhANG (0,5,20 and 40 ? g) as a single bolus were administered intraarterialy via the catheters inserted into the bifurcation of the iliac artery. Revascularization and perfusion of the ischemic limb were compared in each animal postoperatively by using 99 Tc MAA perfusion scan, serial angiography and thigh muscle biopsy. Rabbits in the 20?g group and the 40?g group had significantly better revascularization and blood perfusion than the control group and the 5?g group.It is concluded that rhANG can promote blood purfusion, revascularization and recovery.

To assess the principles of diagnosis and management of Klippel Trenaunay Syndrome (KTS), ascending venography and PPG were used as the means of diagnosis for KTS. 18 cases received nonoperative therapy with elastic bandages or stockings, and 26 patients were operated on, including stripping of varicose vein, decompression of popliteal vein and segmental transplantation with valve to femoral or popliteal vein. The effective rate in the operative group was 73.1% (19/26),whereas the illness of 18 patients was stable with elastic support. Thirty one of 44 patients have been improved during 1～10 year follow up period . It is important that the indications and styles of operation must be carefully considered according to the clinical manifestations and venogram.
