Objective To study the reliability and validity of clinical experts questionnaire of syndrome factors, characteristics and evolution of coronary heart disease. Methods The clinical expert questionnaire was sent to 305 clinical doctors of cardiovascular disease. The questionnaire of coronary heart disease was described through four phases data, and reliability and validity of each module and the total scale were tested. Results Cronbach's ? coefficient of the modules varies between 0.959 3~0.972 5 and higher than 0.8, the value of the scale was 0.990 3. Split-half reliability of the modules varies between 0.891 8~0.922 5, Cronbach's ? of split-half reliability of the total scale was 0.920 7. Factor analysis showed that each module was abstracted four factors and the total contribution rate was more than 50%, the result after varimax rotation was consistent with the theory. Conclusion The questionnaire can fully reflect symptoms and signs of patients with coronary heart disease, and can be used for syndrome studies of coronary heart disease.

Objective To investigate the risk factors of severe hemolysis during extracorporeal membrane oxygenation (ECMO). Methods The clinical data of adult patients undergoing ECMO after cardiac surgery admitted to Fuwai Hospital from December 2010 to October 2015 were retrospectively analyzed. Demographic characteristics, renal function, primary disease, operation data, ECMO related data and outcomes were recorded. Patients were divided into normal free hemoglobin (FHB) group (FHB ≤ 500 mg/L) and severe hemolysis group (FHB > 500 mg/L) according to the FHB level during ECMO support. The parameters before and after ECMO support were compared between the two groups. Logistic regression was used to identify the independent risk factors of severe hemolysis. Results A total of 81 patients including 19 patients with severe hemolysis was enrolled, and 62 in normal FHB group. There was no difference in cardiopulmonary bypass (CPB) time, clamping time, lactate level before ECMO, cardiopulmonary resuscitation, intra-aortic balloon pump use and central catheter insertion between two groups. The maximums of serum creatinine (SCr) and FHB levels were higher in severe hemolysis group as compared with those in normal FHB group [maximal SCr (μmol/L): 281.02±164.11 vs. 196.67±87.31, maximal FHB (mg/L): 600 (600, 700) vs. 200 (100, 300)], the incidence of clots in circuit or oxygenator, infection, and hemofiltration in severe hemolysis group was increased [26.3% (5/19) vs. 4.8% (3/62), 31.6% (6/19) vs. 12.9% (8/62), 36.8% (7/19) vs. 14.5% (9/62), all P < 0.1]. As well as outcomes including the rate of site of surgery or intubation bleeding and acute renal failure [ARF, 57.9 % (11/19) vs. 30.6% (19/62), 94.7% (18/19) vs. 41.9% (26/62)], and the survival rate was lowered [10.5% (2/19) vs. 51.6% (32/62), all P < 0.05]. As result of univariate analysis, clots in circuit or oxygenator, infection and hemofiltration were associated with severe hemolysis. It was showed by logistic regression analysis that the clots in circuit or oxygenator was a risk factor of severe hemolysis during ECMO [odds ratio (OR) = 6.262, 95% confidence interval (95%CI) = 1.244-31.515, P = 0.026]. Conclusions The clots in circuit or oxygenator were independent risk factors of severe hemolysis during ECMO. Severe hemolysis can induce the increase of the rate of bleeding in the operation site or intubation and the rate of ARF, and decrease of the survival rate.

Objective To explore the clinical features of chronic myelogenous leukemia (CML) combined with solid malignant neoplasms. Methods The clinical data of 8 CML patients with solid malignant neoplasms who were admitted to the Affiliated Tumor Hospital of Zhengzhou University, the Central Hospital of Nanyang City, the First Affiliated Hospital of Science and Technology University of Henan, and the Central Hospital of Xinxiang City from August 2006 to August 2018 were analyzed retrospectively. The clinical features, treatment and prognosis of the patients were summarized with the review of literature. Results Among the 8 patients, 3 were male and 5 female, aged 40-76 years, with a median of 50 years old. Seven cases were in CML chronic phase, and 1 was in accelerated phase. Seven patients were treated with tyrosine kinase inhibitor (TKI), and only 1 patient was treated with hydroxyurea. In 8 patients, two cases presented with synchronous multiple primary cancer (SMPC), 6 cases presented with heterochrony multiple primary cancer (HMPC). two patients received the operation, 1 patient received the operation and chemotherapy, 4 patients received chemotherapy, and 1 patient received the isotope treatment. One SMPC patient died and another one was under treatment, and 6 HMPC patients were under treatment. ConclusionsThe relationship between CML and solid malignant neoplasm is under discussion, but patients with CML and solid malignant neoplasm are not unusual. Clinicians should raise awareness to avoid misdiagnosis. The treatment should follow the two main lines that are comprehensive treatment and individualized treatment.
