Objective To investigate the influence of Wenxin granules and bisoprolol fumarate combined with aerobic exercise on serum matrix metalloproteinase -1(MMP -1) and N - terminal pro - brain natriuretic peptide (NT - proBNP) levels in patients with unstable angina pectoris. Methods From January 2016 to February 2018, 92 patients with unstable angina pectoris in Lishui Hospital of Traditional Chinese Medicine were selected and randomly divided into control group(n = 46) and study group(n = 46) according to the digital table. On the basis of routine intervention,the control group was given bisoprolol fumarate for 2 weeks and aerobic exercise for 1 month, while the study group was given bisoprolol fumarate,aerobic exercise and Wenxin granules for 2 weeks. The frequency and duration of angina pectoris before and after 1 month of treatment,clinical efficacy,serum MMP -1 and NT - proBNP levels,blood rheology index(plasma viscosity,whole blood high shear viscosity,total blood low - cut viscosity,fibrinogen) and incidence of adverse reactions were observed. Results After 1 month of treatment,the frequency of angina pectoris was lower than that before treatment,and the duration was shorter than that before treatment,which in the study group [(2. 09 ± 0. 65)times/ week,(2. 24 ± 0. 83)min/ time] were better than those in the control group(t1 = 10. 898,t2 =9. 302,all P < 0. 05). The total effective rate of the study group(91. 30% ) was higher than that of the control group (73. 91% )(χ2 = 4. 842,P < 0. 05). After 1 month of treatment,the serum levels of MMP - 1 and NT - proBNP in the two groups were lower than those before treatment,which in the study group[(196. 10 ± 55. 01) g/ L,(403. 82 ± 114. 15)ng/ L] were lower than those in the control group ( t1 = 3. 619, t2 = 4. 185, P < 0. 05). At the end of treatment,the plasma viscosity,whole blood high - viscosity,whole blood low - cut viscosity,fibrinogen level in the two groups were lower than those before treatment,which in the study group were lower than those in the control group(all P < 0. 05). The incidence rate of adverse reactions in the study group was 15. 22% ,which in the control group was 10. 87% ,there was no statistically significant difference between the two groups (χ2 = 0. 383,P > 0. 05). Conclusion The combination of Wenxin granules, bisoprolol fumarate and aerobic exercise for patients with unstable angina pectoris not only can reduce the frequency of angina pectoris,MMP - 1 and NT - proBNP levels,but also can improve the treatment of disease. Besides,it does not increase the risk of adverse reactions.

Objective:To evaluate the relationship between the mechanism of promoting wound healing by modified autologous blood transfusion and metastasis-associated lung adenocarcinoma transcript 1 ( MALAT1) in diabetic mice. Methods:Twenty SPF ICR mice, weighing 21-25 g, in which the diabetic model was successfully established, were divided into 2 groups ( n=10 each) using a random number table method: modified preservation group (group I) and ordinary preservation group (group O). Peripheral venous blood samples were collected and stored in the corresponding preservation solution for 7 days.The platelet aggregation rate, blood glucose, serum glycosylated hemoglobin (GHB) and phosphodiesterase (DPG) concentrations and WBC were measured.Autologous blood was transfused back immediately after the wound model was established.The percentage of wound healing area was calculated at 7, 10 and 14 days after autologous blood transfusion.The expression of hypoxia-inducible factor-1α, vascular endothelial growth factor, matrix metalloproteinase-9, β-actin, type Ⅰ collagen (Col Ⅰ), Col Ⅲ protein and mRNA and MALAT1 was determined by Western blot, immunohistochemistry and quantitative real-time polymerase chain reaction respectively, at 14 days after transfusion. Results:Compared with group O, the blood glucose, serum concentrations of GHB and DPG, and WBC were significantly decreased, platelet aggregation rate was increased, the percentage of wound healing area was increased, the positive staining rate of Col Ⅰ and Col Ⅲ was increased, and the expression of hypoxia-inducible factor-1α, vascular endothelial growth factor, matrix metalloproteinase-9, ColⅠ, Col Ⅲ and β-actin protein and mRNA and MALAT1 was up-regulated in group I ( P<0.05). Conclusion:The mechanism by which modified autologous blood transfusion promotes wound healing may be related to up-regulating MALAT1 expression in diabetic mice.

Objective To explore the characteristics of illness attribution of outpatients with multiple somatic symptoms in Peking Union Medical College Hospital. Methods It was a cross-sectional study conducted from March to October,2012. A total of 150 outpatients were recruited from the departments of Gastroenterology,Traditional Chinese Medicine and Psychological Medicine by convenience sampling. Somatic symptom scale of the Patient Health Questionnaire (PHQ-15) was used to screening each patient in the waiting list. With the cut-off value of 10,patients were divided into the somatic symptom positive (SOM+) group and somatic symptom negative (SOM-) group. Sociodemographic characteristics were compared between these two groups. All the subjects completed interviews including questions about illness attribution. All the answers of illness attribution were concluded into three major groups as physical factors,situational factors and psychological factors. Results The proportion of female was significantly higher in SOM+ group than in SOM-group (69.3% vs. 53.3%;χ=4.048,P=0.044). In SOM+ group,significantly more patients contributed their illness to psychological factors (64.0% vs. 45.0%;χ=5.273,P=0.022). There was no significantly difference between SOM+ group and SOM-group on the phenomenon of multiple illness attribution (41.0% vs. 32.0%;χ=1.407,P=0.236). However,in the Department of Gastroenterology,there were significantly more outpatients in SOM+ group with multiple illness attribution (60.0% vs. 32.0%;χ=3.945,P=0.047).Conclusions The outpatients in general hospital with multiple somatic symptoms are more likely to contribute their illness to psychological factors. The phenomenon of multiple illness attribution is common among patients. Clinicians should increase their awareness and knowledge of illness attribution,so as to provide better holistic health services.

Objective To investigate the inhibitory effect of blocking PI3K/AKT pathway by wortmannin on hypoxia-inducible factor 1α (HIF-1α) and the effect on the expression of glycolysis associated genes in human esophageal carcinoma cell lines TE1 and TE13,and to analyze the relation between PI3K/AKT-HIF-1α pathway and glycolysis in esophageal carcinoma cells. Methods Esophageal carcinoma cell lines TE1 and TE13 pretreated with wortmannin (2 μmol/L) were incubated under normoxic and hypoxic conditions.And each cell line was divided into four groups.The expression of HIF-1α and glycolysis associated genes GLUT-1,LDHA and HK-Ⅱ at protein level were measured by.Western blot.The expression of HIF-1α,GLUT-1,LDHA and HK-Ⅱ at mRNA level was determined by real-time PCR. The activities of LDH and HK-Ⅱ and lactic acid (LA)concentration in the culture supernatant were tested with spectrophotometer method.Results Under normoxic condition,HIF-1α was expressed in TE1 cells and the expression of HIF-1α was inhibited by wortmannin (2 μmol/L),the most significant inhibitory effect was at 12 hours,therefore 12 hours was selected for the subsequent hypoxia experiment.Compared with untreated cells,the expression of HIF-1α、HK-Ⅱ 、GLUT-1、LDH-A at protein level significantly decreased in TE1 and TE13 cells after pretreated with wortmannin (P < 0.05),and the expression of HIF-1α、HK-Ⅱ at mRNA level significantly decreased (P< 0.05).Under normoxic and hypoxic conditions,the HK-Ⅱ and LDH activities in TE1 and Te13 esophageal carcinoma cells significantly decreased after treated with wortmannin compared with untreated cells (P<0.05).Under hypoxia condition,the enzyme activity increased in untreated cells (P< 0.05). Under normoxic and hyp0xic conditions,the lactic acid concentration in the culture supernatant obviously decreased in cells treated with wortmannin compared with untreated cells (P< 0.05). Under hypoxia condition,lactic acid concentration increased in wortmannin treated cells (P < 0.05). Conclusions Under normoxic and hypoxic conditions,wortmannin decrease lactic acid concentration through inhibiting the expression of HIF-1α and glycolysis associated genes, which indicate PI3K/AKT-HIF-1α pathway was closely related to glycolysis in esophageal carcinoma cells.
