OBJECTIVETo determine whether autoantibodies against beta(1)-adrenergic and M(2)-muscarinic receptors are related to patients with congestive heart failure (CHF).

METHODSBoth synthetic peptides corresponding to amino acids sequence 197-222 and 169-173 of the second extracellular loops of the beta(1) and M(2) receptors were used as antigens to screen sera from 265 patients.188 were congestive heart failure ( CHF) patients with different heart diseases, among them 42 were ischemic cardiomyopathy (ICD) and 52 were idiopathic dilated cardiomyopathy (IDCM) 44 were hypertensive heart disease (HHD) 50 were rheumatic valvular heart disease (RVHD); 77 were controls, among them 36 were simple hypertension and 41 were healthy donors (NC).

RESULTSPositive sera for beta(1)-adrenergic receptor was found in 45.73% (86/188) of CHF patients, while in the controls it was 10.4% (8/77) (P < 0.01); positive sera for M(2)-muscarinic receptor in CHF patients was found in 49.5% (99/188), while in the control it was 11.7% (9/77) (P < 0.01). The positive ratio of autoantibodies against beta(1)-adrenergic and M(2)-muscarinic receptors in CHF patients with cardiac function class II-III (NYHA) were significantly higher than cardiac function class IV. The average titer of autoantibodies against beta(1)-adrenergic and M(2)-muscarinic receptors of the former was significantly higher than the latter; 56.1% of patients with autoantibodies against beta(1)-adrenergic receptor had autoantibodies against M(2)-muscarinic receptor.

CONCLUSIONSAutoantibodies against beta(1)-adrenergic receptor and M(2)-muscarinic receptor were found in sera from heart failure patients with different cardiac diseases. We propose that autoantibodies against beta(1) and M(2) receptors are not only related to the IDCM, but also to cardiac structural and functional changes.

Objective:To explore the relationship between the hypertensive snowbirds′ length of migratory stay and their blood pressure control and blood pressure levels.Methods:This study was a cross-sectional study. A population of snowbirds with hypertension was recruited between October and November 2022, and a structured questionnaire was used to collect their self-measured blood pressure and length of stay in Hainan Province. The blood pressure control status is determined based on self-measured blood pressure. According to the self-measured blood pressure to determine whether the blood pressure was well controlled. The associations between snowbirds′ length of stay and their blood pressure control as well as their self-measured blood pressure were analyzed using restricted cubic splines.Results:A total of 362 research subjects were included, 169(46.7%) of whom were male, and their age was (69.7±7.0) years old. The participants′ self-measured systolic blood pressure and diastolic blood pressure were (129.1±16.2) mmHg (1 mmHg=0.133 kPa) and (78.9±10.1) mmHg, respectively. Overall, 174 (48.1%) participants attained adequate blood pressure control. The median length of stay in Wuzhishan City was 7(6, 7) months. There was an inverted U-shaped association between snowbirds′ length of stay and blood pressure control (overall: P=0.023; nonlinearity: P=0.014), where participants with a length of stay of 7 months had the highest rate of blood pressure control. There is a U-shaped curve relationship between length of stay and systolic blood pressure (overall: P=0.001; nonlinearity: P=0.033), and a linear negative correlation with diastolic blood pressure ( β=-1.19, P=0.003). Conclusions:Compared with hypertensive snowbirds with too long or too short lengths of stay, snowbirds who stayed in Wuzhishan City for seven months have better blood pressure control, and systolic blood pressure is also lower.

Objective To evaluate the feasibility of a valved stent on closure patent ductus arteriosas in a Chinese miniswine model. Methods Self-expandable nitinol stents were made of Ni-Ti shape memory alloy (9 nun in diameter). Bovine pericardium was shaped and sutured onto the stents. Fluid passing test, pre-releasing test and static test of pressure in tube were performed in all devices before use. In eight Chinese miniswine, vascular grafts (PTFE vascular prosthesis) were surgically inserted between the descending thoracic aorta and pulmonary artery for establishment of patent duetus arteriasus model Valved stents were deployed to occlude the patent ductus arteriosus. Echocardiography was performed two hours post operation. Aortic angiography was made 30 days post operation in survived animals. Animals were then sacrificed for autopsy and electron microscopy examinations. Results In vitro testing showed that the closure of the valved stent leaflets was satisfactory and fluid flows were not restricted in the opposite direction. The valved stenta could be released through catheter, expanded completely, rapidly fixed in the tube. Closure of patent ductus arteriosas was succeeded in 6 out of 8 animals. One animal died of respiratory failure 2 hours post operation, another one died of pulmonary embolism due to valved stent displacement. Resident shunt was not evidenced by echocardiography, aortic angiography and dissection examinations in the remaining 6 animals. The new endothelial tissue fully covered the pulmonary and aortic sides of patent ductus arteriosus in 4 and 3 animals respectively. The electron microscopic observation revealed endothelial coverage of diveea. Conclusion The valved stent could effectively close artificial patent dactus arteriosus in vivo with satisfactory new intima covering on beth sides of patent ductus arteriosus.
