Objective:To investigate the technique and clinical effect of repairing 2 soft tissue defects on the same finger with a pedicled tandem flap of the first dorsal metatarsal artery and the second toe tibial artery.Methods:From March, 2018 to May, 2020, 8 patients, which were 5 males and 3 females, with 2 soft tissue defects in the same finger, were repaired with the first dorsal metatarsal artery flap in series with the second toe tibial flap. The causes of injury: 4 by crush, 2 by heavy object, and 2 by thermal press. There were 4 defects on index fingers, 2 on middle fingers and 2 on ring fingers. The defects ranged from 2.0 cm×2.5 cm to 2.5 cm×3.0 cm. All defects had exposed bone or tendon at varying degrees and 3 with phalanx fractures. Three patients underwent emergency surgery, the other 5 had sub-emergency surgery which were performed 3 to 5 days after the injury. The size of the flaps was 2.0 cm×2.5 cm to 3.0 cm×3.5 cm. The donor sites were sutured directly in 3 patients and 5 patients received skin grafting. The regular follow-up was performed. The survival of flaps, character, feeling and Total active motion(TAM), recovery of the foot donor area and complications were observed.Results:The operation time ranged from 2.0 to 5.5 hours, with an average of 3.5 hours. No vascular crisis occurred and all flaps survived after the surgery. All patients entered follow-up for 3-20 months, with an average of 8 months. The flaps had a good plump appearance, soft texture, good elasticity, and with a high similarity to the surrounding skin. The TPD of the flaps was 6-15 mm, with an average of 8 mm. The fingers had good flexion and extension functions. The incision in the donor site of the foot healed by first intention. The walking, running and jumping were normal without pain or discomfort.Conclusion:The first dorsal metatarsal artery-second toe tibial artery tandem flap has been used to repair 2 soft tissue defects in same finger. It simplifies the revascularisation of the flap together with exact surgical curative effect.

Prospective study on efficiency and safety of fondaparinux and enoxaparin in treatment of Chinese patients with acute coronary syndrome having undergoneing PCI / 实用医学杂志

Objective To study efficiency and safety of fondaparinux and Enoxaparin in treatment of Chinese patients with acute coronary syndrome (ACS) having undergone percutaneous coronary intervention (PCI). Methods One thousand and sixty ACS patients (945 with unstable angina, 115 with AMI) having undergone PCI in Henan provincial hospital from July 2011 to July 2013 were randomized into two groups treated with fondaparinux or enoxaparin respectively. Apart from treatment with oral aspirin and clopidogrel, those in the former group were treated with fondaparinux (2.5 mg IH QD) and the latter with enoxaparin (60 mg IH Q12H) subcutaneously for 2 days before operation, both suspended for 12 h before the operation. All of the patients were given heparin (60 IU/kg) during the operation. After the operation, the therapies with fondaparinux (2.5 mg IH QD) and enoxaparin (60 mg IH Q12H) were resumed subcutaneously for 3 days. Perioperative observation and follow-ups were made in terms of hemorrhage, thrombosis and major adverse cardiac events (MACE) in the patients during the hospitalization period, 2 and 4 weeks after operation. Results Fondaparinux and enoxaparin are both effective on anticoagulation for the patients after PCI. There was no significant difference about the incidence of MACE between the two groups (P > 0.05). But, fondaparinux group had lower incidence of hemorrhage than enoxaparin group (P < 0.05). Conclusion Fondaparinux and enoxaparin both have good anticoagulant activity in Chinese patients with ACS undergoing PCI, but fondaparinux may lower the risk of hemorrhage compared to enoxaparin.

Psychological stress increases expression of aortic plaque intercellular adhesion molecule-1 and serum inflammatory cytokines in atherosclerotic rabbit model / 老年心脏病学杂志（英文版）

Plaque rupture,platelet aggregation,and thrombogenesis are the main mechanisms of acute coronary syndrome (ACS),and inflammation factors play key roles in plaque unstability.Psychological stress promotes acute inflammatory response,leading to increased circulating levels of C-reactive protein (CRP),IL-6,and serum intercellular adhesion molecule (sICAM)-1.But it is not clear that whether psychological stress has a direct effect on atherosclerotic plaque stability.The purpose of this study was to investigate effects of chronic psychological stress on inflammatory marker (ICAM-1 ) in atherosclerotic plaque,and inflammatory markers in peripheral blood.Materials and methods Sixty male rabbits were randomized into 2 groups:the control group (n =10) and the atherosclerotic group (n =50).The latter were fed on high fatty diet and were given a large dose of vitamin D3 (3 600 000IU/kg) via intraperitoneal injection.After 8 weeks,the atherosclerotic model was estaslished.Then the 50 atherosclerotic model rabbits were divided into 3 subgroups:no-stress subgroup (n = 16),physiological stress subgroup (n = 16) and psychological stress subgroup (n =18).In physiological stress subgroup and psychological stress subgroup,drinking was cut from twice a day to once a day.At the same time,psychological stress subgroup was given empty bottle stress,and this process lasted for 2 weeks.One hour after the last stress,the blood samples were collected and the serum levels of CRP,IL-6 amd ICAM-1 were tested by radioimmunoassay or enzyme linked immunosorbent assay.The aorta and heart were extracted for pathology examination,and the express of ICAM-1 was tested by immunohistochemical examination.Results (1) After effective atherosclerotic animal model construction,the expression of ICAM-1 in aorta was higher in atherosclerotic group than that in control group (P＜0.01),and was notably higher in psychological stress subgroup than that in no-stress subgroup or in physiological stress subgroup (2.18±0.17 vs 1.58±0.22,1.22±0.15,P＜0.001,respectively).The expression in physiological stress subgroup was higher than that in no-stress subgroup (584±0.22 vs 1.22±0.15,P=0.001).(2) The serum level of IL-6 (51.80±4.60 pg/ml vs 27.60±4.19 pg/ml,8.01±1.39 pg/ml,7.83±1.37 pg/ml),sICAM-1 ( 1.24±0.25 vs 0.85±0.09,0.62±0.17,0.57±0.11),CRP ( 1.004±0.37 vs 0.90±0.29,1.01±0.22,0.71±0.13) in psychological stress group were significantly higher than that in other groups (All P＜0.05).There was a positive relationship between the serum level of CRP,IL-6 and ICAM-1 and the expression of ICAM-1 in aorta wall ( r =0.59,r =0.75,r =0.87,P＜0.01,respectively).Conclusions Psychological stress induces an increased expression of ICAM-1 in aortic atherosclerotic plaque,a higher serum level of CRP,IL-6,and sICAM-1 expression.Psychologial stress has a direct effect on the transition from stability to unstability through in-plaque and out-plaque inflammation.The serum level of CRP,IL-6 and ICAM-1 can reflex the inflammatory degree in atherosclerotic plaque.(J Geriatr Cardiol 2008;5:235-242)

The compliance with secondary prevention and the relationship with the long-term outcome in patients undergoing percutaneous coronary intervention / 中国综合临床

Objective To investigate the compliance of secondary prevention and the relationship with the long-term outcomes in patients undergoing percutaneous coronary intervention(PCI).Methods 589 patients undergoing PCI were followed-up,and factors including major adverse cardiac events(MACE)),smoking status and the usage of antiplatelet agents,angiotensin converting enzyme inhibitor(ACEI)/angiotensin Ⅱ receptor blocker(ARB),statins,beta blocker,calcium channel blocker and nitrates were recorded.Results The average follow-up time was 18.92 months.At discharge,588 patients(99.83%)were prescribed clopidogrel for(7.89±4.96)months;there were 31 patients(5.26%)who completely discontinued antiplatelet therapy during follow-up.At discharge,the prescription rate of aspirin,ACEI/ARB,beta blocker,statins,calcium channel blocker and nitrates was 98.98%,41.94%,63.50%,83.02%,19.69%and 46.52%respectively,whereas at follow-up,these were decreased to 94.4%,35.99%,55.86%,65.89%,17.49%and 35.31%.At follow-up,there were still 105 current smokers(17.83%).Complete cessation of antiplatelet therapy and current smoking were related to the increased risk of non-fatal myocardial infarct(9.68%v.s.1.08%,P＜0.01);smoking(4.76%v.s.0.83%,P＜0.01)andMACE(19.35%v.s.6.45%,P＜0.01);smoking(11.43%v.s.6.20%,P＜0.05).Conclusion Most patients can adhere to secondary prevention during follow-up,however,the compliance with secondary prevention should be improved further.Cessation of antiplatelet therapy and current smoking contribute to poor prognosis.
