Abstract
OBJECTIVE To investigate clinical features and outcomes of Chinese patients with Takotsubo syndrome (TTS). METHODS We established the first Chinese Registry of Takotsubo Syndrome (ChiTTS Registry) and analyzed demographic, clinical, therapeutical, and outcome data to characterize clinical and outcome features of Chinese TTS patients. RESULTS In 112 enrolled patients in the ChiTTS registry from 02/01/2016 to 12/28/2021, the mean age was 59.4 ± 18.7 years old, and 27.7% were men. A total of 41.1% patients experienced respiratory and circulatory complications during hospitalization, and 17.3% patients developed cardiogenic shock. Physical triggers, dyspnea, tachycardia, and younger age (< 70 years old) predicted in-hospital complications. The MACCE rate during follow up was 13.9% per patient per year and the rate of all-cause death was 12.8% per patient per year. TTS patients with in-hospital complications developed more long-term MACCE (24.6% vs. 6.6% per patient-year, P < 0.001) and higher all-cause mortality (21.9% vs. 6.6% per patient-year, P = 0.001) than those without. The Kaplan-Meier survival analysis showed that more MACCE occurred in TTS patients with tachycardia during 3-year follow-up (HR 4.18; 95% CI 1.80-9.74; log-rank test P < 0.001). Among all medications at discharge, only beta-blocker was associated with reduced long-term MACCE (HR: 0.35; 95% CI: 0.12-0.996; P = 0.049). CONCLUSION We investigated clinical and outcome features of patients in the first Chinese TTS Registry. Tachycardiac TTS patients developed more inpatient and long-term adverse cardiovascular events.

Abstract
Ninety normal individuals were included in this study on skin types, skin colours and cutaneous responses to ultraviolet radiation. Skin types were recorded using Fitzpatrick's classification, skin colours were measured using the Minolta Chromameter CR-300, and cutaneous responses to UV radiation were measured in terms of minimal erythema dose (MED) to UVA, UVB and the immediate pigment darkening dose to UVA (IPDDA). Skin colour measurements were taken from the right cheek to represent facultative skin colours, and from the buttock to represent constitutive skin colours. The colours measured were expressed by the L x a x b colour space. Skin types and some colour parameters (L and b from covered parts of body) correlated fairly well with the minimal erythema doses (MED) to UVA and UVB. Skin colour measurements are more objective than skin type assessment and could be better markers of photosensitivity. However, there is still considerable overlap in MEDs for persons with different skin colours, and further studies of these parameters are warranted. Our MEDs are higher than other reports on similar skin types and skin colours. This could be due to differences in methodology, genetic make-up or acclimatization from chronic sun exposure. This illustrates the importance of local controls for each institution dealing with photosensitive disorders.

Abstract
The goal of this study was to evaluate the relative contribution of the renin-angiotensin system and mean arterial pressure to sodium excretion and urine flow rate during an infusion of atrial natriuretic peptide (ANP) at physiologically relevant doses in humans. Eight normal volunteers were studied during five periods: (1) baseline in the supine position; (2) during an infusion of ANP at physiologic doses (0.01 micrograms/kg/min) in the supine position; (3) during ANP infusion and 60 degrees head-up tilt; (4) during ANP infusion, head-up tilt, and interruption of the renin-angiotensin axis with the angiotensin converting enzyme inhibitor (ACEI) enalaprilat; and (5) in the supine position during ANP infusion and ACEI. Infusion of ANP in the supine posture significantly increased urine flow rate and sodium excretion compared to baseline while mean arterial pressure and plasma renin activity were unchanged. During head-up tilt and ANP infusion, urine flow rate and sodium excretion were no longer significantly elevated over baseline while mean arterial pressure decreased and plasma angiotensin II levels increased. Addition of ACEI caused a marked diminution of urine flow rate and sodium excretion compared to baseline levels despite continued ANP infusion. Although mean arterial pressure after ACEI administration was lower than baseline, it was not significantly different from the non-ACEI head-up tilt state. Placing subjects in the supine position during ANP infusion and ACEI administration increased mean arterial pressure to levels that were no longer different from baseline, but urine flow rate and sodium excretion remained significantly depressed to the same degree as during head-up tilt with ACEI.(ABSTRACT TRUNCATED AT 250 WORDS)
