Objective: To evaluate the clinical effect of vonoprazan fumarate on laryngopharyngeal reflux disease (LPRD). Methods: The clinical data of 89 patients from June 2020 to January 2022, including 45 males and 44 females, aged 18-77 (45.54±13.53) years old, were retrospectively analyzed. All the patients were diagnosed as suspected LPRD according to reflux symptom index (RSI) and reflux finding score (RFS). Patients of the Vonoprazan Fumarate group were prescribed Vonoprazan Fumarate orally (20 mg, qd) for 8 weeks.Patients of the Esomeprazole group were prescribed Esomeprazole orally (20 mg, bid) for 8 weeks. RSI and RFS of all the patients before and after treatment were compared. SPSS 18.0 was used for statistics analysis. Results: Before treatment, gender, age, RSI and RFS of the two groups had no obvious differences. After treatment, RSI and RFS in both groups were alleviated significantly. In the vonorazan fumarate group, the RSI before treatment was 12.62±7.18, and after treatment was 4.74±3.87(t=6.91, P<0.001), the RFS was 10.78±2.29 before treatment and 8.24±2.45 after treatment (t=7.06, P<0.001). While in the esomeprazole group, the RSI was 13.27±6.95 before treatment and 6.02±4.28 after treatment (t=7.50, P<0.001), the RFS was 10.59±3.14 before treatment and 8.14±3.30 after treatment (t=5.41, P<0.001). There was no significant difference in the effective rate between the two groups (86.7% in the vonoprazan fumarate group and 77.3% in the esomeprazole group, χ²=1.443, P=0.486). Conclusion: Vonoprazan fumarate could effectively alleviate the symptoms and signs of LPRD patients. The effect of vonoprazan fumarate on LPRD is not inferior to Esomeprazole. It can be used as a supplement to PPI.

BACKGROUNDAliskiren is a novel blood pressure-lowering agent acting as an oral direct renin inhibitor. The aim of this study was to assess the effect of aliskiren on arterial stiffness, compared with that of ramipril in mild to moderate essential hypertensive patients.

METHODSFollowing a two week placebo run-in period, patients with a mean sitting diastolic blood pressure (ms-DBP) ≥ 95 and < 110 mmHg (1 mmHg = 0.133 kPa), and a mean sitting systolic blood pressure (ms-SBP) < 180 mmHg were randomly allocated to treatment with aliskiren (150 mg/d, n = 20) or ramipril (5 mg/d, n = 20) for eight weeks. Blood pressure, plasma renin activity, and the brachial-ankle pulse wave velocity (ba-PWV) were measured before and after eight weeks of treatment.

RESULTSEight weeks of treatment significantly decreased systolic blood pressure and diastolic blood pressure in both the aliskiren group and ramipril group. The hypotensive effect did not differ between the two groups. Plasma renin activity decreased after aliskiren treatment and increased after ramipril treatment. There was no significant difference in baseline ba-PWV between the aliskiren and ramipril groups (P = 0.892). The ba-PWV was significantly reduced in both the aliskiren group (1535 (1405 - 1666) vs. 1464 (1360 - 1506) cm/s) (P < 0.01) and the ramipril group (1544 (1433 - 1673) vs. 1447 (1327 - 1549) cm/s) (P < 0.01). No statistically significant difference was found in the decline of ba-PWV between the two groups (P = 0.766).

CONCLUSIONSThe current study revealed that aliskiren (150 mg/d) could ameliorate arterial stiffness and its effect was similar to ramipril (5 mg/d) in mild to moderate hypertensive patients, indicating that in addition to lowering blood pressure, aliskiren had beneficial effect on vascular protection.

BACKGROUNDAliskiren is an oral renin inhibitor, which inhibits the first rate limiting step in the renin angiotensin aldosterone system. In this study, sympathetic nerve sprouting and the inducibility of ventricular fibrillation after aliskiren treatment in myocardial infarction were investigated.

METHODSMale Sprague Dawley rats after coronary artery ligation were randomly allocated to four groups: angiotensin converting enzyme inhibitor enalapril, angiotensin receptor blocker valsartan, β adrenergic receptor blocker carvedilol and rennin inhibitor aliskiren treatment for six weeks. Electrophysiological study, histological examination and Western blotting were performed.

RESULTSThe plasma norepinephrine level and sympathetic nerve innervation significantly increased in treated infarcted rats compared to untreated rats. Aliskiren treatment reduced the sympathetic nerve innervations after myocardial infarction. There is no significant difference in sympathetic nerve innervations after myocardial infarction among the enalapril, valsartan, carvediloand or aliskiren treated groups. Programmed electrical stimulation study showed that inducible ventricular arrhythmia was reduced, ventricular fibrillation threshold was increased and ventricular effective refractory period was prolonged in enalapril, valsartan, carvedilol and aliskiren treated infarcted rats compared to untreated infarcted rats. Cardiomyocytic apoptosis in infarcted region was significantly decreased in enalapril, valsartan, carvedilol and aliskiren treated infarcted rats.

CONCLUSIONSAliskiren ameliorated cardiomyocytic apoptosis, attenuated the sympathetic nerve innervations and reduced the vulnerability of ventricular arrhythmias after myocardial infarction. Enalapril, valsartan and carvedilol have similar effects as aliskiren on cardiomyocytic apoptosis, sympathetic nerve innervations and vulnerability of ventricular arrhythmias after myocardial infarction.
