Slow coronary flow phenomenon(SCFP) is an angiographic observation characterized by delayed distal vessel opacification in the absence of significant epicardial coronary disease. Only limited studies have been focused on the etiologies, clinical manifestations and treatment of this unique angiographic phenomenon. In our case report, we described an 85-year-old man who came with significant ST segment elevation in leads V1-V4 and V3R-V5R without increase in myocardial enzyme. The patient also developed respiratory failure requiring intubation and mechanical ventilation. Coronary angiography revealed only mild atherosclerosis without spasm or thromboembolic occlusion. Slow flow was seen in all coronary arteries, especially in the left anterior descending and right coronary arteries. This case speculated that transmural myocardial ischemia with ST segment elevation might be resulted from slow coronary flow. Transmural myocardial ischemia can occur owing to abnormalities of the coronary microcirculation.

Objective To investigate the analysis of Symbicort in stable stage of chronic obstructive pulmonary disease treatment and intervention. Methods 80 patients with chronic obstructive pulmonary disease in stable period from June 2014-2016 year in May in our hospital were randomly divided into control group and experimental group, 40 cases in each group. The control group of patients with the use of simple Symbicort treatment and routine nursing care to patients, patients in the experimental group using Symbicort combined with Bailing Capsule for treatment, and the implementation of targeted nursing intervention measures, compare the effect of two groups of patients and nursing satisfaction. Results the clinical treatment of patients in the experimental group the total efficiency 95.0%, nursing satisfaction was 97.5%, the control of clinical patients in the treatment group the total effective rate was 80.0%, nursing satisfaction was 87.5%, the experimental group was significantly higher than the control group, the difference was statistically significant (P<0.05). Conclusion Chronic In the stable period of obstructive pulmonary disease, the combination of Xin Yi capsule combined with Bailing capsule can effectively improve the pulmonary function of patients and improve the clinical therapeutic effect, and is worthy of popularization and application in clinic.

Objective To analyze the characteristics and changes in the disease spectrum of Air Force(AF) servicemen in order to provide reference for the determinatron of the overall level of health of AF and priorities of disease prevention and control.Methods The data of outpatient and inpatient diseases between 2009 and 2013 in AF was collected and analyzed statistically according to the International Classification of Diseases-9(ICD-9),and statistical description was performed with SPSS18.0.Results Between 2009 and 2013,unit B had the highest number of outpatients and inpatients,accounting for 47.74% and 39.64% respectively.The upper respiratory tract infections,gastroenteritis/gastritis,chronic low back pain,skin diseases,nasal sinusitis,training injury,trauma,hemorrhoids,varicocele and stone diseases were the common and frequently occurring diseases in AF,which were the top ten in the disease spectrum.Among them,the incidence and admission rate of skin diseases kept declining.However,the incidence of gastroenteritis/gastritis in unit A,the incidence and admission rate of chronic low back pain in unit B and D,the incidence of injury in unit D,as well as the incidence of neurological headache and hypertension in unit C and D were higher than in other units.Conclusion Respiratory system disease,and occupation-related diseases such as low back pain,training injuries,trauma,skin disease and digestive system disease are the focus of health care in AF.Health education and health promotion for these diseases should be improved,and health intervention for key populations should be enhanced.

To investigate plasma N-terminal pro-brain natriuretic peptide (NT-BNP) levels and to assess their clinical significance in elderly patients with isolated diastolic dysfunction. Methods Plasma NT-BNP level were measured by electrochemiluminescence immunoassay in 34 symptomatic patients (Group 1), 34 asymptomatic patients (Group 2) with isolated diastolic dysfunction, and in 16elderly healthy subjects (control group, Group 3), serving controls. Colored Doppler echocardiography was performed to evaluate the patients' cardiac structures and functions. Results The plasma NT-BNP level in Group 1 was significantly higher than those in Group 2 and Group 3 and increased with the severity of heart failure. There was no significant difference of plasma NT-BNP levels between Group 2 and Group 3 (p＞0.05). A NT-BNP value of 102.75 pg/mL showed a sensitivity of 88.2%, a specificity of 87.5%, and an accuracy of 88.1% for diagnosing diastolic dysfunction. Patients with restrictive filling pattern on echocardiography had higher NTBNP levels than those of impaired relaxation pattern (1961.2±304.9 versus 460. 1±92.7pg/mL, p＜0.001). Conclusion The elevation of plasma NT-BNP level in elderly patients with isolated diastolic dysfunction correlates with the severity of their diastolic abnormalities.The level of plasma NT-BNP has an important clinical value in the diagnosis of elderly patients with isolated diastolic dysfunction.

Objective To investigate the biological function of IFN-λ in 7 human esophageal carcinoma cells. MethodsThe gene expression of IL-28α, IL-10β and antiviral molecule was examined with PCR. The MHC molecules expression and the profiles of cell cycle were analyzed with flow cytometer. Cell proliferation was evaluated with MTT assay. ResultsAll of esophageal carcinoma cells express the gene of II-28α and IL-10β. IFN-λ induced or augmented the gene expression of antiviral molecules, 2′5′-OAS and MxA. IFN-λ enhanced the MHC class Ⅰ molecule expression. IFN-λ inhibited the growth of esophageal carcinoma cells through the regulation of cell cycle distribution. ConclusionEsophageal carcinoma cells express the IFN-λ receptor complex. IFN-λ has the antiviral, anti-proliferative and immunoregulation activity.

OBJECTIVETo investigate whether the angiotensin II type I receptor gene (AGTR1) A1166C polymorphism is associated with a high risk of diabetic nephropathy.

METHODSThe allele frequency and the genotype distribution of the AGTR1 A1166C polymorphism were studied in normal controls (157 cases), simple diabetes (141 cases, duration of diabetes >10 years), and diabetic nephropathy (152 cases) by means of polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

RESULTSPatients with diabetic nephropathy had a higher frequency of C allele of the AGTR1 A1166C polymorphism than that of normal controls and simple diabetes (P<0.05); but there was no significant difference in frequency of C allele between the normal controls and patients with simple diabetes.

CONCLUSIONThe diabetic patients with AGTR1 C allele may be more susceptible to diabetic nephropathy than diabetic patients with A allele.

OBJECTIVEThe objective of this study is to investigate the association between laryngeal carcinoma and laryngopharyngeal reflux.

METHODSThis was a case-control study with 31 laryngeal cancer patients who had undergone 24-hour ambulatory double pH monitoring and 76 in the control group which were divided into negative group (36 patients) and positive group (40 patients) by the score of RSI (reflux symptom index) and RFI (reflux findings index) scale. The results of reflux and parameters of 24-hour ambulatory double pH monitoring among the three groups were statistically analysed.

RESULTSThe smoking rate of 80.6% (25/31) in laryngeal carcinoma group was significantly higher than that of (36.1%, P < 0.0167) in the negative group while it did not vary in laryngeal carcinoma group and the positive group (65.0%, P > 0.0167). The drinking rate of 71.0% (22/31) in laryngeal carcinoma group was higher than that of (36.1%, P < 0.0167) in the negative group whereas there was no significant difference between laryngeal carcinoma group and positive group (50.0%, P > 0.0167). The positive rate of laryngopharyngeal reflux in laryngeal carcinoma group, the positive group, the negative group were 74.2% (23/31), 16.7% (6/36) and 52.5% (21/40) respectively, which was significantly different (P < 0.05). The positive rate of gastroesophageal reflux in the three groups above were 71.0% (22/31), 52.8% (19/36) and 75.0% (30/40), which had no significant difference (P > 0.05). The positive rate of laryngopharyngeal reflux differed in laryngeal carcinoma group and the negative group (P < 0.0167) while did not differ in laryngeal carcinoma group and the positive group (P > 0.0167). In the results of 24-hour ambulatory double pH monitoring, there was significant difference in the total and upright reflux number, the total reflux time, the percent times for the pH falling below 4, total reflux number which lasted more than 5 minutes and DeMeester Scores.

CONCLUSIONSThe positive rate of laryngopharyngeal reflux in laryngeal carcinoma group was very high while the drinking and smoking rate were also high. Therefore whether the laryngopharyngeal reflux is a risk factor of the laryngeal carcinoma, it needs further research.
