Objective To study the relation between hyperglycaemia and the prognosis in patients with type 2 diabetes mellitus undergoing coronary revascularization. Methods Study retrospectively 334 type 2 diabetes mellitus patients underwent coronary revascularization, we compare the incidence of hyperglycaemia between patients with good prognosis and patients with bad prognosis undergoing coronary artery bypass graft and percutaneous transluminal coronary angioplasty. We identify by logistic regression analysis the extent of hyperglycaemia as risk factor in the prognosis individually. Results In patients undergoing coronary artery bypass graft and percutaneous transluminal coronary angioplasty, the incidence of hyperglycaemia is higher in patients with bad prognosis than in patients with good prognosis. It is identified by logistic regression analysis that hyperglycaemia deteriorates the prognosis of patients undergoing coronary artery bypass graft (OR=2.033, P=0.008) and patients undergoing percutaneous transluminal coronary angioplasty (OR=2.476, P=0.006). Conclusion To control hyperglycaemia efficiently following coronary revascularization in patients with type 2 diabetes mellitus is mandatory.

Objective:To summarize and analyze the disease characteristics of the patients in Chinese Level-II Hospital for UN Peacekeepers in Liberia,for offering some references to the pre-mission training of the successive contingents as well as the improvement of medical support to the peacekeeping mission.Methods:A statistical analysis was made of the case history of all the outpatients and inpatients received in Chinese Level-Ⅱ Hospital for UN Peacekeepers in Liberia from May 2004 to December 2005. Results:Out of the total of 7107 outpatients,2539(35.7%) were medical cases,1205(17.0%) surgical,1136(16.0%) dental,787(11.1%) dermatological and 763(10.7%) contagious cases.Malaria was the main type of contagious disease,which accounted for 86.1% of all the contagious cases.There were 39 cases of AIDS/HIV(acquired immunodeficiency syndrome / human immunodeficiency virus).Of the 453 inpatients,233(51.4%) were contagious and 166(36.7%) medical cases,and 185(40.8%) of the total number suffered from malaria.The average hospital stay was 5.2 days.Conclusion:Adequate drugs and equipments should be prepared for both common and special diseases in the peacekeeping mission area.During the pre-mission training at home,special emphasis should be laid on the prevention and treatment of common diseases and frequently occurring diseases,particularly on the diagnosis of and protection against AIDS.

Objective To observe the efficacy of Wuteng Ercao decoction in treating active rheumatoid arthritis (RA) and its effects on the levels of cytokine interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α).Methods Sixty-five patients with active RA were randomly divided into treatment group (33 cases) and control group (32 cases). Patients in the control group were administered with methotrexate tablets 10 mg, oral taking, once a week;hydroxychloroquine sulfate tablets 200 mg, oral taking, twice a day;diclofenac sodium sustained release tablets 75 mg, oral taking, twice a day. Patients in the treatment group were administered with Wuteng Ercao decoction additionally, oral taking, three times a day. The treatment lasted for 12 weeks. The changes and untoward effects of various clinical and laboratory indicators were observed before and after treatment.Results After treatment, the tender joint count, swollen joint count, patient’s global assessment, and physician’s global assessment were improved (P<0.05), with statistical significance between the two groups (P<0.05). The levels of ESR, CRP, IL-6 and TNF-α decreased significantly after treatment (P<0.05), but those were more significantly in treatment group (P<0.05). There were 2 cases with untoward effects in the treatment group and 1 case in the control group (P>0.05).Conclusion Wuteng Ercao decoction is effective in patients with active RA and it can reduce the levels of IL-6 and TNF-α.

Objective To evaluate the clinical effects of two different revascularization approaches,one via percutaneous coronary intervention (PCI) with drug-eluting stents (DES) and the other via coronary artery bypass graft (CABG),on short-and long-term prognosis in elderly patients with diabetes and multi-vessel coronary artery disease.Methods A retrospective analysis was conducted on 254 elderly patients with diabetes and multi-vessel coronary artery disease.Based on the revascularization approach,patients were divided into the PCI group (n=93) and the CABG group (n =161).The incidence of major cardiovascular events (MACE) were observed during hospitalization and 1-year after follow-up.Results All-cause mortality and the incidence of non-fatal myocardial infarction were higher in the CABG group than in the PCI group during hospitalization [4.9％ (8 cases) vs.1.1％ (1 cases),5.6％ (9 cases) vs.2.2％ (2 cases),each P＜0.05],while there was no significant difference in the incidence of MACE between the two groups1-year after follow-up (P＞ 0.05).The incidence of cerebrovascular events was lower in the PCI group than in the CABG group [2.2 ％ (2 cases) vs.6.2％ (10 cases),P＜0.05],while the rate of revascularization was higher in thePCI group than in the CABG group [6.5％ (6 cases) vs.1.9％ (3 cases),P＜0.05].Cox regression analysis showed that diabetes (OR =1.65,95％ CI:1.013-1.926,P =0.024) and left ventricular ejection fraction (OR =1.30,95 ％ CI:1.018-1.652,P =0.027) were independent risk factors for revascularization and cerebrovascular events.Conclusions MACEs during hospitalization are fewer in elderly patients with diabetes and multi-vessel coronary artery heart disease who received PCI than in those who received CABG.PCI has a similar mid-and long-term effect as CABG,bur PCI has a higher revascularization rate and lower risk of MACEs than CABG.

Objective: To evaluate the impact of anemia on prognosis of elder patients with acute coronary syndrome (ACS) after percutaneous coronary intervention (PCI).
Methods: A total of 908 consecutive ACS patients elder than 60 years of age with PCI in our hospital from 2010-06 to 2012-06 were studied. According to WHO deifnition of anemia (HB<12.0 g/dL in female and HB<13.0 g/dL in male), the patients were classiifed as Anemia group, n=283 and Non-anemia group, n=625. The patients were followed-up for 1 year. The basic clinical characteristics, incidences of mortality and major adverse cardiovascular and cerebravascular events (MACCE) were compared between 2 groups by cardiac death, myocardial re-infarction, worsening of cardiac function, target vessel revascularization, cerebral hemorrhage and cerebral infarction.
Results: There were 31%of patients suffering from anemia. Anemia group had more patients with the elder age, female gender, diabetes, hypertension, chronic kidney disease, decreased LVEF, more patients with 3 vessel-disease, and higher mortality at 1 year after PCI, higher rate of MACCE than those in Non-anemia group, all P<0.05. Multiple regression analysis indicated that anemia is the independent predictor for mortality in elder ACS patients at 1 year after PCI, P<0.05.
Conclusion: Anemia may increase the incidences of mortality and MACCE in elder ACS patients after PCI for a long-term.

Objective To investigate and compare the predictive value of 2 prediction scoring systems for diagnosis of coronary heart disease (CHD) in patients with suspected symptom, and provide information for diagnosis and therapy. Methods By prospectively studying a database of 272 patients with suspected CHD,the total score was calculated by prediction scoring system including PROCAM (The Prospective Cardiovascular Munster Study) and SCP(Suspected CHD Prediction Scoring System) with the data of clinic parameters and risk factors. All patients received coronary angiography and they were categorized into the CHD group (n =94) and non CHD group ( =178) according to the angiography result. The relationship between total scores and the SYNTAX score was evaluated by Spearman analysis and the value of the prediction scoring system was evaluated by the ROC (receiver operating characteristic) system. Results The score of PROCAM was from 6. 00 -77. 00(41. 76 ± 19. 91), and the score was significantly correlated with the extent and severity of coronary artery atherosclerosis (rs = 0. 420,P = 0. 023). The score of SCP was from 1. 00 - 13. 00(8. 64 ± 3. 42), and it was significantly correlated with the SYNTAX score (rs = 0. 482,P = 0. 016). The areas under ROC was 0. 770 (P = 0. 007) in PROCAM and that was 0. 733 (P = 0. 012) in SCP. Conclusions The nature and extent of coronary artery atherosclerosis could be evaluated by the scoring system effectively,which had a good correlation with CAG result.

Objective Excimer laser coronary atherecomy ( ELCA) has been recently used for the treatment of complex coronary lesions including calcified stenosis , chronic total occlusions and in-stent restenosis. Such complex lesions are difficult to adequately treat with balloon angioplasty and /or intracoronary stenting.The aim of this study was to introduce our early experiences in using ELCA in China . Methods Fifteen patients were enrolled through our center from March 2015 to April 2016 , and excimer laser coronary angioplasty was performed on 15 lesions.Eleven patients were previously failed cases either from uncrossable balloon ( 9 lesions ) or expandable balloon ( 6 lesions ) . The procedure and clinical endpoints were recorded .Results Laser catheter with 0.9 mm diameters were used in all 15 coronary lesions.All the lesions were successfully crossed with laser catheter and finally dilated with balloon .The procedural success rate was 100%.Drug eluting stents ( DES ) were implanted in 86.7% lesions and 2 cases were treated with drug eluting balloon .Clinical success was obtained in all patients (100%).There was no dissection , major side branch occlusion , spasm, no-reflow phenomenon nor acute vessel closure . Conclusions This study shows that laser-facilitated coronary angioplasty is a simple , safe and effective device for the management of complex coronary lesions .

PURPOSE: Several studies have compared the effects of coronary stenting and coronary-artery bypass grafting (CABG) on left main coronary artery (LMCA) disease. However, there are limited data on the long-term outcomes of these two interventions in diabetic patients. MATERIALS AND METHODS: We evaluated 56 patients with LMCA stenosis who underwent drug-eluting stent (DES) implantation and 116 patients who underwent CABG in a single hospital in China between January 2004 and December 2006. We compared long-term major adverse cardiac events (death; a "serious outcome" composite of death, myocardial infarction, or stroke; and target-vessel revascularization). RESULTS: In-hospital (30-day) mortality was 0% for the DES group and 3.4% for the CABG group (p=0.31). There was no difference between the two groups in terms of risk of death [hazard ratio for stenting group, 0.49; 95% confidence interval (CI), 0.13-1.63; p=0.55] or risk of serious outcome (hazard ratio for DES group, 1.11; 95% CI, 0.39-1.45; p=0.47). The target-vessel revascularization rate was higher in the DES group than in the CABG group (hazard ratio, 3.67; 95% CI, 1.24-11.06; p=0.018). CONCLUSION: In this cohort of diabetic patients with LMCA stenosis, there was no difference in composite endpoints between patients receiving DESs and those undergoing CABG. However, stenting was associated with higher rates of target-vessel revascularization than CABG. DES implantation in diabetic patients with LMCA disease was found to be at least as safe as CABG.

Objective To identify the risk factors of major bleeding in patients undergoing off-pump coronary artery by-pass grafting( OPCAB) .Methods Data on coronary artery disease patients who underwent off-pump CABG between December 2009 and December 2014 were reviewed.Baseline characteristics were compared between patients with clopidogrel discontinua-tion ≥5 days and <5 days.Univariate and multivariate logistic regression analyses were performed to investigate the risk fac-tors of perioperative major bleeding.Major bleeding was defined as the Universal Definition of Perioperative Bleeding(UDPB) class 3 -4.Results A total of 3988 patients who underwent OPCAB were included in this study.Major bleeding rate was 9.23%(n=368).Multivariable regression analysis showed that female sex(OR=1.99, 95%CI:1.57-2.52), age(OR=1. 02, 95%CI:1.00-1.03), lower BMI(BMI≤25 kg/m2)(OR=1.40,95%CI:1.12-1.75), decreased GRF(GFR<60 ml/min)(OR=1.43,95%CI:1.01-2.02), decreased preoperative Hct(Hct <0.40)(OR =1.57, 95%CI: 1.23-1.99) and clopidogrel discontinuation <5 days(OR=1.97, 95%CI:1.58-2.44) conferred a higher risk of perioperative major bleeding during OPCABG.Conclusion Female, advanced age, lower BMI, decreased GRF, decreased preoperative Hct and clopi-dogrel discontinuation<5 days are independent risk factors of perioperatice major bleeding in patients undergoing OPCAB .Pre-dicting risk of major bleeding can help sugeons to optimize perioperative management .

Objective:To compare the safety and effectiveness of direct stenting versus deferred stenting for the treatment of acute ST segment elevation myocardial infarction(STEMI)with a high thrombus load in patients aged 60 years and above.Methods:In this study, we analyzed 252 elderly STEMI patients with a high thrombus load(thrombus score ≥ 4 points)who received percutaneous coronary intervention(PCI)at Beijing Anzhen Hospital Affiliated or at the Affiliated Hospital of Beihua University from January 2015 to December 2018.They were divided into the direct stent group(n = 126)and the deferred stent group(n = 126)according to whether the stent was inserted immediately or not.Baseline information, surgical information, clinical outcomes and major adverse cardiac events were compared between the two groups at 1 year follow-up.Cox regression analysis was used to determine whether deferred stent implantation was a prognostic factor.Results:There were no significant differences in the distribution of infarct-related arteries, time from onset to balloon dilatation, thrombus load scores and the number of stents between the two groups(all P> 0.05). The diameter and length of the stent were(3.20 ± 0.47)mm and(18.33 ± 5.06)mm in the deferred stent group and(3.03 ± 0.50)mm and(22.60 ± 5.08)mm in the direct stent group, respectively, with a significant difference between the two groups( t=2.926, 6.678, P=0.004, 0.000). The incidences of slow blood flow, distal embolism and low myocardial perfusion staining in the deferred stent group were 2.38%(3/126), 3.17%(4/126)and 2.38%(3/126), respectively, significantly lower than those in the direct stent group, which were 15.87%(20/126), 24.60%(31/126)and 20.63%(26/126), respectively( χ2=13.827, 24.188, 20.614, all P=0.000). The left ventricular ejection fraction(LVEF)at 1 year in the deferred stent group was (0.60±0.05)%, significantly higher than that in the direct stent group(0.57±0.05)%( t=3.859, P=0.000). There was no significant difference in major adverse cardiac events between the two groups at 1 year follow-up( P> 0.05). Cox regression analysis results showed that deferred stent implantation was not a factor affecting the clinical outcome( HR=0.827, 95% CI: 0.288~2.372, P=0.724). Conclusions:Deferred stent implantation and direct stent intervention are equally safe and effective for STEMI patients aged over 60 with a high thrombus load if admitted to the hospital within 12 hours after onset.Deferred stent implantation can significantly improve the infarct-related artery blood flow classification, reduce the distal embolism rate, increase the grade 3 rate of myocardial perfusion staining, increase the diameter of the stent, reduce the length of the stent and improve left ventricular ejection fraction.
