Ischemic stroke is a critical society-medicine-economy problem,and effective therapy is rather insufficient.Nowadays,method of promoting blood circulation and removing blood stasis was popularly adopted,but only enjoyed limited curative effect in segmental stage of illness in patients.In this article,we analyzed and discussed mainly concept and viewpoint on blood stasis syndrome in Traditional Chinese Medicine,moreover,and provided advanced data for experimental and clinical research in the future.

Objective To investigate the effects of VEGF-induced expression of Survivin by colon cancer cells(LOVO,HCT116) and human umbilical vein endothelial cells(HUVECs).Methods VEGF was used to stimulate the LOVO,HCT116,HUVECs.We used RT-PCR and Western blot to estimate the expression of Survivin in different cells,and immunocytochemistry to investigate the expression level and site of Survivin protein.ResultsSurvivin was expressed highly in the cytoplasm and was upregulated with the induction of VEGF.In HUVECs,Survivin expression was not obvious but significantly upregulated with the inductioin of VEGF in the cytoplasm and nucleus.Conclusion The expression of Survivin mRNA and protein are upregulated by VEGF stimulation.The level and distribution of Survivin are different in tumor cell lines and non-tumorgenicity cells.

Objective To probe the application of superimposed flaps in hand surgery. Methods Form March 1998 to December 2003, we repaired 35 cases of skin defects with non trunk blood flaps and neurocutaneous vascular flaps. The area of flaps ranged from 1cm?1cm to 6cm?8cm. Results After operation, the flaps in 33 cases survived, but died in 2 cases due to unsuitable design. The follow ups ranging from 6 to 12 months showed that the quality and color of the survived flaps were similar to those of the normal tissue around. No swelling was found. Conclusion The superimposed flaps have reliable blood supply so that they are an ideal means to repair skin defects of hand.

Objective To investigate the effects of VEGF-induced expression of Survivin by colon cancer cells (LOVO, HCT116) and human umbilical vein endothelial cells (HUVECs). Methods VEGF was used to stimu-late the LOVO, HCT116, HUVECs.

AIM: To quantitatively investigate transforming growth factor-β(TGF-β) and its receptors in normal bulbar conjunctival tissues and pterygium tissues. METHODS: Thirty cases of pterygium patients were randomly selected to undergo surgical resection of pterygium lesion, and the normal margin of bulbar con-junctival tissues were collected as control. Gene expres-sion was detected quantitatively by the method of quantitative real-time PCR (QRT-PCR) analysis. RESULTS: The expression level of TGF-β1 and TGF-β2 was 4.26×10-7±1.45×10-7 and 1.08×10-10±0.68×10-10 in normal bulbar conjunctival tissues, while 10.67×10-7±7.47×10-7 and 8.23×10-11±6.63×10-11 in pterygium tissues. The expression level of TGF-βRⅠand TGF-βRⅡwas 0.003015±0.0036 and 5.33×10-5±5.05×10-5in normal bulbar conjunctival tissues, while 0.000379±0.000281 and 1.002×10-5±9.04×10-6 in pterygium tissues. The expression level of TGF-β1 and TGF-β2 in pterygium was elevated (P<0.01). TGF-β1 expression level in pterygium increase 2.9±2.8 times than in normal conjunctiva. TGF-β2 expression level in pterygium increase 7.5±1.4 times than in normal conjunctiva. The expression level of TGF-βRⅠin pterygium was significantly lower (P<0.05). The expression level of TGF-βRII in pterygium was significantly lower (P<0.01). CONCLUSION: QRT-PCR is an effective method to quantitatively detect gene expression in eye. The upregulation of TGF-β1 and TGF-β2 and downregulation of their receptors expression may play an important role in the pathogenesis of pterygium, which is noteworthy further investigation in diagnosis and treatment of pterygium.real-time PCR; gene expression

Objective To retrospectively analyze diagnosis and treatment of chronic pancreatitis. Methods One thousand and seven hundreds patients with confirmed chronic pancreatitis in 21 hospitals were retrospectively studied,including their associated etiological factors,diagnostic and therapeutic methods.Results Among these patients,601 were alcoholic,576 were biliary diseases origin,which ac- counted for 35.4% and 33.9%,respectively.The most common symptom of chronic pancreatitis was abdominal pain.Some of patients accompanied by steatorrhoea and decreased body weight.Part of pa tients(239 cases)were diagnosed by histopathologic examination.Others were diagnosed by imaging techniques.Alleviation of symptoms was achieved with conservative management.Conclusions Alcohol consumption was the most common predisposing factor for chronic pancreatitis.Imaging techniques play the most important role in diagnosis of the disease,and non-operation managements were the main meth- ods for treatment of chronic pancreatitis.

OBJECTIVETo compare clinical effects of spinal leveraging manipulation and medicine for the treatment of degenerative scoliosis in pain and function.

METHODSFrom July 2010 to June 2013, 38 patients with degenerative scoliosis were randomly divided into spinal leveraging manipulation group and medicine group by coin tossing. In manipulation group, there were 9 males and 11 females aged from 58 to 74 years old with an average of (66.63±7.73), the courses of diseases ranged from 3 to 8 months with an average of (5.65±2.58), spinal leveraging manipulation(following meridian to straighten tendon,relieving spasm, osteopathy and massage, clearing and activating the channels and collaterals) were performed for 30 min, once a day, 4 days for a period treatment, totally 9 courses. In medicine group, there were 8 males and 10 females aged from 57 to 70 years old with an average of (63.51±6.61) the courses of diseases ranged from 3 to 5 months with an average of (4.82±1.43), celecoxib with eperisone hydrochloride were orally taken, 4 days for a period treatment, totally 9 courses. VAS score, Cobb angle and ODI score were measured.

RESULTSAfter treatment, VAS score in manipulation group was (5.38±0.99), (6.36±1.31) in medicine group,and had significant meaning (t=2.618, P<0.05); there was significant differences in Cobb angle between manipulation group (16.51±4.89)° and medicine group (19.85±5.03) °(t=2.074,P<0.05); and had obviously meaning in ODI score between manipulation group (20.20±2.93) and medicine group (26.01±3.11) (t=5.592, P<0.05).

Opioid analgesics are potent pain-killer and are widely used in clinical practice.Opioid receptors are classified into μ,δ,κ subtypes.Most of the currently available opioid analgesics are μ opioid receptor agonists, but they cause undesired side effects such as physical dependence, respiratory depression and constipation and so on.The antalgic activity of δ receptor agonist is weaker than that of μ agonist, but it can modulate the activity of μ receptor and prevent its addiction. Therefore, discovering and designing compounds with μ/δ dual action is a new way for finding analgesics with low toxicity and less side effects.This review summarizes the development of compound with dual μ/δ activities and provides a new strategy for designing analgesics with low toxicity and less side effects.

Objective The use of extracorporeal membrane oxygenation (ECMO) as a treatment for the failure of cardiopulmonary function after cardiac surgery is increasing and has been reported to be 3% to 5% in the cases with congenital heart disease. We reviewed our experience with ECMO in children who received heart surgery for congenital heart disease and complicated with severe heart failure postoperatively. Methods Eight patients received ECMO, seven was due to the failure to wean from bypass and one had fulminant myocarditis. Import membrane oxygenator,veno-arterial mode ECMO and right atriumascending aortic cannulation were used in 7 cases and peripheral cannulation via femoral veno-artery route was used in 1 case.Supportive intervention persisted from 65 to 498 hours, with flow rate maintained at 80 to 120 ml per minute per kilogram body weight. Results Five patients died, with a mortality of 62.5%, and 3 cases discharged, with a survival rate of 38%. Bleeding occurred in 5 cases, thrombosis occurred in 2 cases, hemolysis was identified in 1 case and DIC was observed in 1 case.One case had liver failure and 2 cases had malnutrition. Oxygenator plasma leakage occurred in 2 cases. Mean arterial blood pressure increased significantly after the establishment of ECMO as compared with that before the procedure [( 60.2 ± 7.8 )mmHg vs. (48. 1 ± 5.2 ) mmHg, P≤0.05]. The arterial concentration of lactate decreased significantly, from (5. 1 ± 0. 8 )mmol per liter before ECMO to ( 3.6 ±0. 5 )mmol per liter after ECMO, P ＜0.05. Conclusion For patients who survived the congenital heart surgery and no residual anatomic deformity, ECMO can be used as early as possible as a treatment for severe heart failure which resulted from coexistent of left and right ventricular and pulmonary insufficiency. An overall mortality may be decreased by ECMO technique as it plays a substitution role for gas exchange in the lung. As a result, the concentration of oxygen and the airway pressure used during ventilation, and the resultant lung injury can be reduced. Appropriate strategies involve transfusion of fresh platelet and packed red blood cells, replacement of frozen plasma and blood products, as well as rational use of vasoactive drugs and heparin, and maintaining a stable internal environment. Following strategies are also recommended: using continuous arterio-venous hemofiltration and durable heparin-coated membrne oxygenator, reducing hemorrhagic complications, monitoring pressure on both side of the film, identifying plasma leakage carefully and reducing the mechanical complications.
