Objective To explore pre-hospital delay factor of coronary reperfusion therapy for ST-elevation acute myocardial infarction (STEAMI) patients presenting with non-chest pains. Methods A retrospective observation was conducted. The clinical data of STEAMI patients underwent emergency percutaneous coronary intervention (PCI) admitted to Luoyang Central Hospital Affiliated to Zhengzhou University from August 2013 to August 2015 were analyzed. The patients were divided into chest pain group and non-chest pain group according to the presence of chest pain or not. Clinical characteristics were compared between the two groups, and incidence of major adverse cardiac events (MACE), door-to-balloon time, door-to-electrocardiograms (ECG) time and ECG-to-balloon time were evaluated. Influencing factors of pre-hospital delay was analyzed by logistic multiple stepwise regression. Results A total of 259 patients with STEAMI were enrolled, including 154 patients with chest pain and 105 presented with non-chest pains. Compared with chest pain group, the patients in the non-chest pain group were older (years: 68.12±8.93 vs. 62.34±7.12, P < 0.05), less female (26.67% vs. 42.20%, P< 0.05), and had a higher past history of angina, stroke and heart failure (27.61% vs. 13.63%, 31.42% vs. 18.83%, 26.67% vs. 11.68%, respectively, all P < 0.05), and higher percentage of Killip ≥ Ⅲ patients (15.24% vs. 6.49%, P < 0.05), the lower ambulance use (26.67% vs. 44.81%, P < 0.01), longer hospitalization time (days: 12.50±2.89 vs. 9.50±2.67, P < 0.05), higher incidence of MACE (19.05% vs. 9.09%, P < 0.05), longer door-to-balloon time and door-to-ECG time (minutes: 159.01±51.21 vs. 115.31±36.74, 53.06±18.17 vs. 30.35±9.93, both P < 0.01). It was shown by logistic multivariate regression analysis that no-chest pain [odds ratio (OR) = 5.14, 95% confidence interval (95%CI) = 2.34-10.81, P < 0.001], age ≥ 65 years old (OR = 1.43, 95%CI = 0.93-2.99, P = 0.022), diabetes (OR = 1.57, 95%CI = 0.66-2.15, P = 0.015) and no-ambulance transport (OR = 1.55, 95%CI = 0.73-2.75, P < 0.001) were risks factors of coronary reperfusion delay ≥ 2 hours. Conclusions STEAMI patients presenting without chest pain showed higher incidences of MACE, longer time of ECG obtained and initial PCI time delay. Clinicians should try to reduce the delay time of the patients in order to improve patient survival rates.

Objective To identify hepatitis C virus(HCV)-specific cytotoxicity T lymphocytes (CTL)epitopes by the combination of T epitopes prediction software and in vitro assays.Methods HCVspecific CTL epitopes were predicted by T epitope prediction software Rankpep and then candidate HCV-specific CTL epitopes were selected.Candidate HCV-specific CTL epitopes were used to stimulate PBMC of HCV-infected patients and healthy volunteers.and then enzyme-linked immunospot(ELISPOT)and intracellular cytokine staining(ICS)were used to measure the frequencies of IFN-γ-producing cells in total PBMC and the percentages of IFN-γ+CD8+T cells in total CD8+T cells,respectively.Results Five candidate CTL epitopes[NS3 450(TVPQDAVSR),NS3 594(GPTLLYRL),Ns4b 78(sMMAFSAAL),NS5a 416(SEENVSVVF)and NS5a 367(TVSSALAEL)]were used to stimulate PBMC of ten HCV-infected patients and two healthy volunteers.PBMC of seven HCV-infected patients secreted IFN-γ while PBMC of healthy volunteers did not produce IFN-γ.The frequencies of peptide-specific IFN-γ-producing cells ranged from 5 to 36 SFC/105 PBMC and the percentages of peptide-specific IFN-γ+CD8+T cells ranged from 0.02%-0.25%.Conclusion Resuhs of ELISPOT assay and ICS assay confirm that these five peptides NS3 450,NS3 594,NS4b 78,NS5a 416 and NS5a 367 are identified as Hovel HCV-specific CTL epitopes.

The historical surveillance results showed, there were 10 schistosomiasis cases in Huangshan City from 1994 to 2006. The survey in 2007 showed, the positive rates of blood examination for schistosomiasis in migrant workers and immigrant workers were 0.49% and 0.47% , respectively, but no schistosome-infected patients were detected by using the stool examination. An area with snails of 3 000 m~2 was found in the residence of the immigrant workers, but no infected snails were found. It is indicated that the mobile population has some impact on the transmission of schistosomiasis in the transmission-interrupted area. The surveillance and health education for the mobile population should be strengthened, and the imported infectious source should be prevented.

Objective To explore the influence of glucose-lowering rate on left ventricular function in patients with type 2 diabetes mellitus (T2DM). Methods One hundred and thirty-two cases of type 2 diabetes mellitus and 135 cases of type 2 diabetes mellitus with coronary heart disease (T2DM+CHD)received intensive glucose lowering therapy. Then, after measuring left ventricular ejection fraction (LVEF) and E/A ratio, the variation was analyzed. Results LVEF was significantly higher than that before intensive therapy in T2DMsubgroup with glucose-lowering rate less than 6 m mol · L-1 · d-1( P＜0.05 ). So was T2DM+CHD subgroup with glucose-lowering rate less than 4 mmol· L-1 · d-1 (P＜0.05). LVEF was significantly lower than that before intensive therapy in T2DM+CHD subgroup with glucose-lowering rate greater than 4 mmol · L-1 · d-1( P＜0. 05 ),while by the end of following up for 3 months, LVEF stepped up and no significant difference was observed between subgroups ( P ＞ 0. 05 ). The E/A ratio stepped up in both subgroups after intensive therapy ( P ＜ 0. 05 ).Conclusions For T2DM patients with coronary heart disease, excessively fast glucose-lowering rate may impair left ventricular function. Long-term good control of blood glucose restores the impaired left ventricular function causes by excessively fast glucose-lowering rate. After intensive therapy, left ventricular diastolic function finally improves in both subgroups regardless of the glucose-lowering rate and coronary heart disease.

Objective To Pulse oximetry saturation has been wildly used clinically.It has been reported that pulse oximetry plethysmographic waveform (POP) reflected the peripheral tissue perfusion.In this study,we parameterized POP,observed the value of POP parameters in normal adults,and established the normal reference value range.Methods A multi-center prospective descriptive study.Total of 1 019 adult volunteers with normovolemia from 7 cities were enrolled in this study.Sex,age,height,weight and pulse oximetry data in awake and spontaneous breathing under in quiet conditions in the room temperature were collected.POP parameters and perfusion index were analyzed using MATLAB 2012a software.The normal reference value ranges of POP parameters,including the amplitude of POP (Amp) and the area under the curve of POP (AUC),were formulated.Results Statistical differences of POP parameters were detected between men and women in the normal adult.The 95％ confidence reference value of POP parameters in normal population was as follows:Amp (104.8-2298.7) PVA and AUC (3265.8-6028.5) PVPGin total,Amp (129.4-2433.6) PVA and AUC (3319.0-5862.2) PVPG in male;Amp (89.5-2138.2) PVA and AUC (3163.9-5929.9) PVPG in female.Conclusions POP,including the amplitude of POP (Amp) and the area under the curve of POP (AUC),had normal reference value ranges in normal adults.

OBJECTIVE: To analyze the clinical phenotype and genetic basis for a child with acute form of tyrosinemia type I (TYRSN1). METHODS: A child with TYRSN1 who presented at the Gansu Provincial Maternal and Child Health Care Hospital in October 2020 was selected as the subject. The child was subjected to tandem mass spectrometry (MS-MS) and urine gas chromatography-mass spectrometry (GC-MS) for the detection of inherited metabolic disorders, in addition with whole exome sequencing (WES). Candidate variants were validated by Sanger sequencing. RESULTS: The child's clinical features included abdominal distension, hepatomegaly, anemia and tendency of bleeding. By mass spectrometry analysis, her serum and urine tyrosine and succinylacetone levels have both exceeded the normal ranges. WES and Sanger sequencing revealed that she has harbored c.1062+5G>A and c.943T>C (p.Cys315Arg) compound heterozygous variants of the FAH gene, which were inherited from her father and mother, respectively. Among these, the c.943T>C was unreported previously. CONCLUSION Considering her clinical phenotype and result of genetic testing, the child was diagnosed with TYRSN1 (acute type). The compound heterozygous variants of the FAH gene probably underlay the disease in this child. Above finding has further expanded the spectrum of FAH gene variants, and provided a basis for accurate treatment, genetic counseling and prenatal diagnosis for her family.
