Stasis is the critical causative factor and pathological production considered in clinic treatment. Promoting the circulation in blood vessel and removing stasis are equally important in treatment. Stasis is interactive with qi and blood. Removing stasis aims to regulating the circulation of qi and blood. Scraping therapy is one of the major approaches to stasis removal in TCM. In clinical practice, the stasis can be removed with scraping, bleeding and cupping, etc. Additionally, removing stasis with scraping should be combined with regulating qi and blood to enhance the therapeutic effect.

To explore the impact of middle and low dose atorvastatin on peripheral endothelial progenitor cells (EPCs) in patients with acute myocardial ischemia injury via investigating EPC proliferation, migration, differentiation and secretion of cytokines. Method: A total of 80 patients with acute ST-segment elevation myocardial infarction (STEMI) were randomly divided into 2 groups: Observation group, the patients received atorvastatin 40 mg and Control group, the patients received atorvastatin 20 mg. n=40 in each group. The number of circulating EPC, EPC proliferation ability and the secretion of cytokines before and at different time points after drug therapy were examined by means of MTT, flow cytometry and ELISA. Results: The number of EPC was obviously increased with greatly changed migration ability within 2 weeks atorvastatin treatment in both groups. The secretion of cytokines presented that the contents of VEGF, bFGF, CXCR were elevating first followed by reducing thereafter, while the content of SIRT1was continuously increasing during the period of treating. The above parameters were similar between 2 groups. Conclusion: Middle and low dose atorvastatin could effectively improve EPC proliferation and migration, increase the expressions of CXCR4, VEGF, bFGF and SIRT1 in STEMI patients.

Objective To explore the method of 3D reconstruction of major blood vessels around the pancreas with Myrian system and its clinical significance.Methods By making use of the data from 64-slice CT of GE,the main arteries,portal vein,spleen vein,superior mesenteric vein and inferior mesenteric vein of 60 pancreases were 3D reconstructed with Myrian system.Vessel length and some other data were also recorded.Results The main arteries and veins were reconstructed.The length of portal vein was (46.37 ± 11.48)mm.The length of postpancreas trunk was (34.88±9.13)mm.The angle between portal vein and spleen vein was acute angle in 17 cases (28.33％),right angle in 11 cases (18.33％) and obtuse angle in 32 cases (53.33％).The inferior mesenteric vein fed into spleen vein in 19 cases (31.67％),superior mesenteric vein in 34 cases (56.67％) and conjunction point between spleen vein and superior mesenteric vein in 7 cases (11.67％).Conclusion Myrian system can be used to reconstruct the 3D structure of blood vessels around the pancreas with high reconstruction rates.This method can also be used in feasibility analysis of clinical operations and reduce the risk of bleeding caused by unknown distribution of blood vessels around the pancreas during operation.

Objective To study the clinical efficacy of recombinant human epidermal growth factor (rhEGF) in the treatment of sacrococcygeal decubitus ulcers grade Ⅲ with direct polymerizing suture after appling rhEGF to reinforce wound bed preparation (WBP). Methods From January 2007 to October 2009, 60 patients with sacrococcygeal decubitus ulcers Grade Ⅲ, were divided into control group and treatment group. The ulcer size was 3 cm × 4 cm to 10 cm × 12 cm and all ulcers were infected for 15-70 d. Treatment group received traditional dressing change and appling rhEGF to reinforce wound bed preparation. Control group received traditional dressing change only. The operative technique that we used in two groups was direct polymerizing suture. Cure rate of stage Ⅰ and complication morbidities were analyzed. Results Cure rate of stage Ⅰ was 87% in treatment group and 70% in control group. Complication morbidities were 13% in treatment group and 30% in control group. The difference between these two groups was statistically significant (P ＜ 0.05). Conclusion Appling rhEGF to reinforce wound bed preparation before operation could make subsequent treatment more effective and improve the cure ratio of operation with decreasing complications and morbidities. And more, dissecting under fascia possesses the advantages of easiness to perform and rich blood supply.The method of appling rhEGF with direct polymerizing suture is a simple, high efficient approach for the first repairment of sacrococcygeal decubitus ulcers grade Ⅲ, especially desirable for the elderly.

Objective To investigate the role of glucose-regulated protein 78 (GRP78) in sevoflurane preconditioning-induced inhibition of apoptosis in cardiomyocytes of rats.Methods The cultured cardiomyocytes of Sprague-Dawley rats were randomly divided into 5 groups (n =30 each) using a random number table:control group (group C),hypoxia-reoxgenation (H/R) group,sevoflurane preconditioning group (group S),siRNA-GRP78 group and siRNA control group.H/R was produced by 2 h exposure of cells to 95％ N2-5％ CO2 in an air-tight chamber at 37 ℃,followed by reoxygenation with 95％ O2-5％ CO2 in an air-tight chamber at 37 ℃ for 1 h.In group S,the cells were incubated with 2.5％ sevoflurane for 20 min,followed by 10-min washout before H/R.In siRNA-GRP78 group,the cells were transfected with siRNA-GRP78 100 nmol/L,and 24 h later preconditioning with sevoflurane was performed and H/R was produced.In siRNA group,cells were transfected with siRNA,and the other treatments were similar to those previously described in siRNA-GRP78 group.After treatment in each group,the expression of GRP78 in myocardial cells and cytochrome c in cytoplasm and mitochondria was detected by Western blot.Lactic dehydrogenase (LDH) and creatine kinase (CK) activities in the culture medium of each group were determined by ELISA.The apoptosis in myocardial cells was assessed by flow cytometry.Apoptotic rate was calculated.Intracellular free Ca2+ concentration ([Ca2+]i) was measured with the fluorescent probe Fura-2/ AM.The opening of mPTP was measured by fluorescence spectrophotometry.Results Compared to group C,the expression of GRP78 in myocardial cells and cytochrome c in cytoplasm was significantly up-regulated,LDH and CK activities in the culture medium,apoptotic rate and [Ca2+]i were increased,and the expression of cytochrome c in mitochondria was down-regulated in H/R group.Compared to group H/R,the expression of GRP78 in myocardial cells and cytochrome c in mitochondria was significantly up-regulated,LDH and CK activities in the culture medium,apoptotic rate,[Ca2+] i and opening of mPTP were decreased,and the expression of cytochrome c in cytoplasm was down-regulated in group S,and no significant change was found in the parameters mentioned above in siRNA group.Compared to group S,the expression of GRP78 in myocardial cells and cytochrome c in mitochondria was significantly down-regulated,LDH and CK activities in the culture medium,apoptotic rate,[Ca2+] i and opening of mPTP were increased,and the expression of cytochrome c in cytoplasm was up-regulated in group siRNA-GRP78.Conclusion GRP78 is involved in sevoflurane preconditioning-induced inhibition of apoptosis in cardiomyocytes of rats,and the mechanism is related to maintenance of intracellular Ca2+ stability and inhibition of opening of mPTP.
