Clinically, chronic obstructive pulmonary disease (COPD) and coronary heart disease (CAD) often interact to promote disease progression. This article discussed that zongqi is the heart-lung correlation functional basis and yingwei relevant is heart-lung correlation core. Zongqi deficiency is the incidence basis of COPD and CAD from the pathology. Communication and transformation of nutrient and defensive qi is the core mechanism of COPD combined with CAD. Phlegm and blood stasis are toxic intricate. Further damage to jingqi is the key to combination of COPD and CAD. It lays the foundation for next clinical syndrome differentiation, development of comprehensive treatment programs and clinical research.

Objective To explore sleep quality and mental health status of chronic obstructive pulmonary disease(COPD) patients with respiratory failure.Methods From October 2015 to June 2016,COPD patients with respiratory failure hospitalized in our hospital were selected as study group.Patients without COPD hospitalized in our hospital were selected as the control group.The sleep quality and mental health were compared between the two groups.Results The age and body mass index (BMI) between the two groups showed no significant difference (t =0.753,0.693,all P ＞0.05).The forced expiratory volume in one second (FEV1％) expected value,arterial oxygen pressure (PaO2),oxygen saturation (SaO2) in the study group were (52.34 ± 12.25) ％,(9.21 ± 1.83) mmHg,(90.36 ± 3.47) ％,which were significantly lower than those in the control group,the differences were statistically significant (t =25.199,5.414,16.439,all P ＜ 0.01).The somatization,obsessive-compulsive symptoms,interpersonal sensitivity,depression,anxiety,terror between the two groups had significant differences (all P ＜ 0.05),the differences in hostility,paranoia and psychosis were not statistically significant (all P ＞ 0.05).The quality of life scale (GQOL-74) scores in cognitive function [(74.47 ± 6.13) points],psychological function [(71.28 ± 7.36) points],physical function [(73.73-± 8.85) points] and social function [(74.35 ± 7.18) points] in the study group were significantly lower than those in the control group,the differences were statistically significant (t =9.735,13.972,5.739,10.040,all P ＜ 0.01).Conclusion The sleep quality and mental health status of COPD patients with respiratory failure is poorer,we should pay more attention and intervention in clinical diagnosis and treatment.

BACKGROUND: Above curative dose, there is a dose-dependent correlation of the survival rate of fat transplantation with vascular endothelial growth factor (VEGF), the curative dose of VEGF determines the tissue volume of transplanted fat. OBJECTIVE: To investigate the changes of the blood supply rebuilding and the survival rate of the fat transplant in the microenvironment of continuous infusion of VEGF using osmotic pump. DESIGN, TIME AND SETTING: A cellular morphology observational experiment was performed from September 2007 to October 2008 in Department of Plastic Surgery at the Affiliated Hospital of Guangdong Medical College. MATERIALS: Ninety healthy SD rats were used to establish autologous fat transplantation models. Human VEGF was produced by American ONCOGEN Corporation. Type Alzet2002 mini-osmotic pump was produced by American Alzet Corporation. METHODS: Ninety rats were equally divided into 3 groups randomly. The operation control group was only processed into autologous fat transplantation; Experimental control group received autologous fat transplantation and continuous infusion of 2 000 ?L physiological saline using osmotic pump at a speed of 0.5 ?L/h for 14 days; Experimental group received autologous fat transplantation and continuous infusion of 2 000 ?L physiological saline containing 1 ?g VEGF using osmotic pump at a speed of 0.5 ?L/h for 14 days. MAIN OUTCOME MEASURES: At the 7th, 14th, 28th, 42nd, 64th days postoperation, the graft’s survival volumes were measured using mini-scale test tube; the cell morphology changes were observed with hematoxylin-eosin stain; The newly born microvessels on experimental group and control groups were researched with immunohistochemistry staining. RESULTS: At 14 days postoperation, the graft’s survival volumes of experimental group was higher than operation control group and experimental control group (P 0.05). At each time point, the vascular density of the fat transplant in the experimental group was higher than that in other groups (P 0.05). CONCLUSION: VEGF can speed up vasifaction and raise fat graft survival significantly.

Ob jectiev Oxidized low-density lipoprotein ( ox-LDL) induces vascular endothelial cell injury , which is one of the factors initiating atherosclerosis .This study aimed to investigate the protective effect of Tongxinluo ( TXL ) on vascular endothelial cells with ox-LDL-induced injury . Methods Human umbilical vein endothelial cells ( HUVEC ) were cultured in vitro and divided into five groups:normal control, oxidative stress injury (OSI) model, and high, medium and low dose TXL.The HUVECs were incubated with ox-LDL at the concentration of 30 mg/L for 24 hours to induce oxidative stress injury and then treated with TXL at 50, 100 and 150 mg/L for 4 hours, followed by 24 hour incubation with 30 mg/L ox-LDL added to the culture medium .The viability of the cells was detected by MTS assay, the nitric oxide (NO) content, superoxide dismutase (SOD) activity and mitochondrial membrane poten-tial ( MMP) in the cell culture supernatant were measured with respective kits , and the expressions of iNOS , MMP9, and NF-κBp65 proteins were determined by Western blot . Results The HUVECs of the OSI model group showed a significant decrease in cell via-bility compared with the normal control , ([73 .89 ±0.67] vs [100.00 ±2.23]%, P<0.01) but a remarkably increase after treated with medium and high dose TXL ([92.15 ±0.76]%and [ 97.19 ±1.45]%, P<0.01).The MMP, NO content, and SOD activity were markedly reduced in the model group (P<0.01) but elevated in the low, medium, and high dose TXL groups (P<0 .01).The expressions of the iNOS, MMP9, and NF-κBp65proteins were significantly up -regulated in the model group (P<0.01) but down reg-ulated in the low, medium, and high dose TXL groups (P<0.05).C on clusion TXL has the effects of anti-oxidation and anti-in-flammation and can protect vascular endothelial cells against ox-LDL-induced injury .

Aim To determine the effects of Qiliqian-gxin injected into lateral ventricle on Cardiac function, angiotensin Ⅱ( Ang Ⅱ) , angiotensin converting en-zyme(ACE), angiotensin type 1 receptor(AT1R) and the sympathetic nervous system in the hypothalamic pa-raventricular nucleus of rats with chronic heart failure. Methods Rat model of heart failure was prepared by acute myocardial infarction that was induced by ligation of the left anterior descending coronary artery. Four weeks after heart failure, Qiliqiangxin and Losartan were continuously administered via a syringe pump in-jector connected to lateral ventricle. After four weeks, echocardiogram was used to evaluate the cardiac func-tion and HE was used to observe myocardial tissue morphology, and enzyme linked immunosorbent assay was used to measure plasma norepinephrine( NE) , ser-um NT-proBNP and Ang Ⅱ in the paraventricular nu-cleus. The expression of ACE and AT1 R at mRNA and protein levels in the paraventricular nucleus was deter-mined by Real-time PCR and Western blot, and the RSNA was measured by PowerLab in anesthetized rats. Results Compared with the sham control, the cardiac function was significantly lower while the AngII, ACE, AT1 R expression in the paraventricular nucleus and RSNA were significantly increased in rats with heart failure. Compared with heart failure control, Qiliqian-gxin and Losartan decreased the RSNA and the AngII, ACE, AT1 R expression in the paraventricular nucleus. Conclusion Giving traditional Chinese medicine to the lateral ventricles can decrease the activation of the RAS system, reduce the renal sympathetic nerve activi-ty and improve cardiac function.

Aim To observe the effect of Guishao-tongluo ( GSTL ) on the angiogenesis of vasa vasorum and oxidative stress in the early stage of atherosclero-sis. Methods The rabbits ( n =84 ) were randomly divided into 7 groups (n=12):control group,high-fat group, adventitial injury group, GSTL high(GH)and medium ( GM ) dose group, atorvastain group ( ATO ) , and Tongxinluo group ( TXL ) . The normal group was fed with common foodstuffs, and high-fat foodstuffs for the high-fat group to establish an early model of hyper-lipidemia, and all the other groups were fed with high-fat diet combined with carotid artery cannula to build early atherosclerosis carotid artery injury rabbit mod-els. The GSTL high and medium dose was given Guishaotongluo ultrafine powder 4. 16,2. 08 g·kg-1 · d-1 respectively. The atorvastain group and Tongxinluo group were given suspension of atorvastain solution 2. 5 mg·kg-1 ·d-1 , Tongxinluo supermicro powder 0. 6 g ·kg-1 ·d-1 . All groups were treated with gastric per-fusion for 4 weeks. Biochemical method was applied to detect blood lipid change. HE staining was used to ob-serve the pathological morphology of intima-media. Aactivity of serum superoxide dismutase( SOD) ,malon-dialdehyde ( MDA ) content and the total antioxidant capacity ( T-AOC ) in artery serum were detected. NADPH subunits p22phox mRNA, gp91phox mRNA in carotid arteries were located and semi-quantitated by fluorescence in situ hybridization. The expression of VEGF, VEGFR-2 in the carotid artery adventitia was detected by Western blot. Results Compared with normal group,the contents of TC,TG and LDL-C were significantly increased, and VEGF, VEGFR-2 protein levels were remarkly increased in high-fat and adventi-tial injury group. The carotid artery injuries,the degree of angiogenesis of vasa vasorum and NADPH subunits p22phox, gp91phox mRNA in adventitia tissue of the GH,GM, ATO and TXL group were milder in varying degrees compared with those of the vasa injury group. Also the activity of SOD,T-AOC increased,while MDA content,VEGF,VEGFR-2 protein levels were remarkly decreased ( P < 0. 5 or P < 0. 01 ) . Conclusions GSTL can inbibit adventitial neovascularization in the early stage of atherosclerosis, and its mechanism might be related to the increase of total antioxidant capacity of the vascular system and adventitia tissue.
