Objective:To explore the application value of combined detection of troponin I (cTnI) and creatine kinase isoenzyme mass (CKMBmass), interleukin-6 (IL-6) and fibrinogen degradation products (FDP) in the diagnosis and treatment of acute myocardial infarction (AMI).Methods:A total of 102 AMI patients in Wanbei Coal Power Group General Hospital from July 2019 to June 2020 were selected as the AMI group. In addition, 60 patients diagnosed with chest pain (CP) and chest distress (CD) during the same period were selected as the CPCD group, and 60 healthy patients were selected as the healthy control group. The levels of cTnI, CKMBmass, IL-6 and FDP in the peripheral blood of the three groups were compared, and the receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of cTnI, CKMBmass, IL-6, and FDP. The AMI group was given thrombolytic therapy. The clinical data of patients with different curative effects, the trend of changes in peripheral blood cTnI, CKMBmass, IL-6 and FDP levels before and after treatment were compared, and the relationship between the above indicators and clinical indicators and curative effects were analyzed.Results:The levels of peripheral blood cTnI, CKMBmass, IL-6 and FDP in the AMI group were higher than those in the CPCD group and the healthy control group, and the levels of peripheral blood cTnI, CKMBmass, IL-6 and FDP in CPCD group were higher than those in the healthy control group ( P<0.05). The area under the curve (AUC) values of cTnI, CKMBmass, IL-6 and FDP in the combined diagnosis of CPCD and AMI were 0.898 and 0.926, respectively, which were higher than those of single diagnosis. The time from onset to thrombolysis, infarct location, diabetes, diastolic blood pressure (DBP), systolic blood pressure (SBP), left ventricular end systolic volume (LVESV), left ventricular end systolic diameter (LVESD), left ventricular end diastolic volume (LVEDV), left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF) on admission of effective patients and ineffective patients were statistically significant ( P<0.05). The levels of peripheral blood cTnI, CKMBmass, IL-6, and FDP of effective patients were lower than those of ineffective patients when they were admitted to the hospital and 6, 12, 24, 48, and 72 h after treatment ( P<0.05). The peripheral blood cTnI, CKMBmass, IL-6, and FDP on admission were positively correlated with DBP, SBP, LVESV, LVESD, LVEDD, LVEDV, and was negatively correlated with LVEF ( P<0.05). Multiple linear stepwise regression analysis showed that after the onset to thrombolysis time, infarct location, smoking, diabetes, SBP, DBP, LVESV, LVESD, LVEDD, LVEDV, LVEF and other factors at admission were controlled, the levels of peripheral blood cTnI, CKMBmass, IL-6, FDP were still significantly related to the efficacy ( P<0.05). Conclusions:The peripheral blood cTnI, CKMBmass, IL-6, and FDP are all abnormally expressed in AMI patients. Combined detection has clinical significance for the diagnosis and treatment of AMI.

Objective To investigate the prevalence and spectrum of β-thalassemia mutations in C, uangdong province, and provide a reference for prenatal diagnosis and genetic counseling in this population. Methods Three thousand two hundred and forty-seven blood samples were randomly selected from Guangzhou and 2984 blood samples from Shenzhen from January in 2005 to January in 2009. PCR and reverse dot blot hybridization (RDB) were adopted for detection of β-thalassemia mutations in Guangzhou and Shenzhen city. Results Seven hundred and fifty-one individuals in Guangzhou were found to have β-hemoglobin gene mutations, the detection rate was 23.13%(751/3247); 10 different mutations were identified, namely CD41-42(-TCTT), IVS-Ⅱ-654(C→T), -28(A→G), CDI7(A→T), CD71-72(+A), 13E, IVS-I-1(G→T), CD43(G→T), -29(A→G), CDI4-15(+G), which accounted for 42.53% (336/790) ,25.19% (199/790), 12.66% (100/790), 10.89% (86/790) ,3.29% (26/790), 2.15%(17/790), 1.27%( 10/790), 1.14%(9/790) ,0.51%(4/790) ,0.38%(3/790), respectively; the most common mutation was CD41-42(-TCTT), which accounted for 42.53%(336/790). In Shenzhen, 179 individuals were found to have β-thalassemia mutations, the detection rate was 6.00% (179/2984); 8 different mutations were identified excluding CD43 (G→T) and CD14-15 (+G); the most common mutation, however, was IVS-lI--654(C→T), which accounted for 40.44% (74/183). Conclusions The β-thalassemia mutations in Guangdong province are not only frequent, but also obviously heterogeneous, and the mutations differ from region to region. CD41-42 (-TCTT),ⅣS-Ⅱ-654(C→T), -28(A→G), CD17(A→T) were the 4 predominant mutations.

Background Whether ocular anterior and posterior chamber exist a blood-aqueous barrier is in controversy.Conventional method can not offer a good evidence because it is unable to detect the aqueous component in the posterior chamber.Objective This study was to investigate the distribution of Gadolinium-diethylene triamine pentaacetic acids(Gd-DTPA)after peripheral iridectomy with magnetic resonance imaging(MRI)in rabbit.Methods Monocular peripheral iridectomy was performed on the right eyes in 8 clean New Zealand white rabbits and the fellow eyes were as controls.0.2 ml/kg(0.5 mol/L)Gd-DTPA,a tracer of MRI,was injected into ear vein in vivo to scan the eyes with MRI for the observation of the permeability and distribution.The signal enhanced ratio of interest region associated with time were analyzed.Results The signal in ciliary body of both eyes showed an immediately sharp enhancement within 10 minutes following the injection of Gd-DTPA with a peak intensity at 30-40 minutes,and then the intensity was gradually weaken over time.The signal was stronger in the operative eyes than that in the fellow eyes.The signal in the posterior chamber was gradually increased after operation,however,that in posterior chamber of the control eyes was lower.The interest regions of Gd-DTPA were ciliary,anterior chamber and posterior chamber,and the enhanced signal intensities were consisted in the posterior chamber after operation.However,the increase of the signal was not seen in the posterior chamber in the control eyes.Conclusions The pathway of plasma protein entering into the anterior chamber is very different from that of aqueous secretion.There exists a barrier between the anterior and posterior chamber which might be an integral part of the blood-ocular barrier.
