Objective To study the meaning of Homocysteine,serum high sensitive C-reactive protein,lipoprotein A and D-two dimer combined detection in the course of coronary heart disease.Methods Select 180 cases suffering from different types of coronary heart disease as group of coronary heart disease,200 healthy people who were in our hospital physical examination qualified over the same period as the control group,all the cases of fasting venous blood was sampled respectively to detect the content of Hcy,hs-CRP,LP(a) and DD.Results Coronary heart disease group of patients with Hcy,hs-CRP,LP(a) and DD levels were significantly higher than those of the control group of healthy persons(t =13.87,10.24,9.86,18.02,P ＜ 0.05),Comparison among different indicators of the patiens with Coronary heart disease:the group of AMI was higher than the group of UAP (t =15.79,9.73,11.47,17.34,all P ＜ 0.05),the group of UAP was higher than the group of SAP (t =16.82,8.14,10.65,18.27,P ＜0.05),the group of SAP was higher than the group of SMI (t =14.36,10.35,9.98,16.52,P ＜ 0.05).Conclusion Monitoring of Hcy,hs-CRP,LP(a) and DD for coronary heart disease,contributes to the understand of the development of the course of coronary heart disease and assess the risk of coronary heart disease.

Objective To investigate the clinical features and antimicrobial susceptibility of neonatal Listeria septicemia.Methods Eleven cases of neonatal Listeria septicemia that were treated in the Huzhou Maternity and Children Health Hospital from March 2013 to March 2017 were enrolled in this study.Clinical data including the results of bacterial culture,antimicrobial susceptibility test and antibiotic treatment were collected and retrospectively analyzed.Moreover,maternal history of Listeria monocytogenes (LM) infection before delivery was retrieved.Results All of the 11 mothers had fever before delivery and nine of them showed different grades of amniotic fluid contamination during delivery.Clinical symptoms of the 11 neonates included dyspnea (11 cases),fever (ten cases),apnea (nine cases),slow response and feeding difficulty (nine cases),convulsion (six cases),vomiting and abdominal distension (two cases),pulmonary hemorrhage (one case),progressive jaundice (one case) and systemic skin bleeding point (one case).All cases showed abnormal results of blood routine test and increased calcitonin and C-reactive protein.Ten cases received cercbrospinal fluid examination,seven of which were abnormal.Altogether 17 strains of LM were isolated from various specimens.These strains were all sensitive to piperacillin-tazobactam,ampicillin-sulbactam,meropenem,vancomycin,cotrimoxazole,ciprofloxacin and gentamycin,but resistant to oxacillin.Strains those were sensitive to penicillin,ampicillin,erythromycin and clindamycin accounted for 10/17,11/17,9/17 and 8/17,respectively.The 11 neonates were treated with piperacillin-tazobactam,meropenem or vancomycin.All of them improved (11/11)and ten were cured (10/11).All cases were followed up through phone calls at one week and one month after discharge.Two were lost to follow-up,while thc others were all in good condition.Conclusions Neonatal Listeria septicemia is usually a severe disease characterized by rapid progression and mainly presented with dyspnea and fever,besides there is a high possibility of purulent meningitis.Some LM strains are resistant to single-agent penicillin antibiotics.However,antibiotics such as piperacillin-tazobactam,meropenem and vancomycin are effective in the treatment of neonatal Listeria septicemia.

Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.
