ObjectiveTo study the relationship between plasma cardiac troponin I (cTnI) and global registry of acute coronary events (GRACE) risk score in patients with acute non ST segment elevation myocardial infarction (NSTEMI),and to assess the value of low GRACE risk score combined with plasma cTnI concentration in predicting hospital cardiovascular events in NSTEMI patients. MethodA total of 168 patients with NSTEMI treated between January 2011 and December 2012 were included in this study. Their serum CTnI level was measured instantly and on the second day (within 24 hours) to get the peak value. GRACE risk score was calculated by computer rating software. According to the GRACE risk score,risk stratification was performed,and patients were divided into low-risk group (n=48),middle-risk group (n=75) and high-risk group (n=45). Routine treatment was carried out for the patients during hospitalization. ResultsThe serum cTnI peak value was higher in high-risk patients than that in low-risk patients and middle-risk patients (P<0.05). The cTnI peak value was significantly higher in the middle-risk patients than in the low-risk patients (P<0.05). The incidence of major adverse cardiovascular events (MACE) in low-risk patients with higher serum cTnI peak value was relatively higher. Age,hyperlipidemia,and serum cTnI were closely related to MACE (P<0.05). ConclusionsFor NSTEMI patients with a low GRACE score,the MACE rate increases with the increase of serum cTnI concentration. GRACE low score and cTnI concentration have a certain clinical value in assessing the risk of MACE in NSTEMI patients.
ObjectiveTo explore the clinical efficacy of immediate breast reconstruction with extended latissimus dorsi musculocutaneous flap after nipple and areola sparing modified radical mastectomy for patients with early-middle breast cancer. MethodsSixty patients diagnosed with early-middle breast cancer by needle biopsy from November 2009 to October 2012 in this hospital were divided into two groups according to the surgical method.The breast reconstruction group (30 cases) were performed immediate breast reconstruction with extended latissimus dorsi musculocutaneous flap after nipple and areola sparing modified radical mastectomy, the control group (30 cases) were performed traditional modified radical mastectomy.The postoperative complications, clinical efficacy, quality of life, and recurrence and metastasis were compared in two groups. Results①The ipsilateral breast was completely missing in the control group.The aesthetic effect in the breast reconstruction group was satisfactory including excellent in 22 patients, good in 7 patients, general in 1 patient.②The rates of flaps effusion, flap necrosis, and affectied limb activity limitation had no significant differences in two groups (P > 0.05).The wound healing time, operation area drainage time, hospital stay, and post-operative chemotherapy start time all had no significant differences in two groups (P > 0.05).③The frequency of psycho-logical pressure (inferiority/anxiety/fear) and rate of un-satisfaction of secondary sexual characteristics (body/curve) in the breast reconstruction group were lower than those in the control group (P < 0.001).The rate of social interaction fitness in the breast reconstruction group was higher than that in the control group (P < 0.001).④The following-up time was 12 to 38 months with an average 25 months, one case died because of brain metastasis in the control group, the rest 59 patients had no local recurrence and distant metastasis. ConclusionsThe immediate breast reconstruction with exte-nded latissimus dorsi musculocutaneous flap after nipple and areola sparing modified radical mastectomy can cure cancer on the basis of satisfactory cosmetic results of breast, excellent quality of life of patients, and fewer surgical complica-tions.It does not affect postoperative adjuvant radiochemotherapy and short-and long-term efficacy for breast cancer.
