Urotensin-Ⅱ is a vasoactive 'somatestatin-like' cyclic peptide. Recently, human urotensin-Ⅱ has been cloned and demonstrated to be the most potent vasoconstrictor identified so far. The receptor of urotensin-Ⅱ has now been identified as the orphan receptor GPR 14 . This peptide may influence cardiovarscular homeostasis, pathology and also influence respiratory system, central nervous system and endocrine function.

Objective To evaluate the prognostic value of enhanced CURB and CURB-65 score in patients with community acquired pneumonia.Methods A retrospective study was conducted among 555 patients with community-acquired pneumonia recruited.According to the patient's 28 day outcome, they were divided into effective group(n=510, 57 cured and 453 improved) and ineffective group(n=45, 30 did not improve and 15 died).The prognosis of the two groups was evaluated using the enhanced CURB and CURB-65 score, the sensitivity and specificity of the two scoring methods were compared.Results Compared with the ineffective group, the age, length of hospital stay and the prevalence of the complications of chronic diseases were significantly lower than the effective group(P<0.05).The score of enhanced CURB and CURB-65 of ineffective group were significantly higher than the effective group(P<0.05).The sensitivity of enhanced CURB score was significantly higher than that of CURB-65 (P<0.05) while its specificity was significantly lower than that of CURB-65(P<0.05).Conclusion The CURB and CURB-65 score in community acquired pneumonia can effectively assess the severity of the disease and thus guide the treatment of patients with community acquired pneumonia.

Objective To investigate the quality of life (QOL) of patients with frequent premature ventricular contractions (PVCs) and the effects of radiofrequency catheter ablation (RFCA) on them.Methods 120 patients with frequent PVCs,100 cases with frequent APCs and 60 healthy persons were assessed by 36-Health survey questionnaire (SF-36) originally.Three months later,the QOL of 48 cases received RFCA and 72 cases with drug therapy were evaluated again by SF-36.Meanwhile,decrease of PVCs were also calculated between these two groups.Results The scores of physiological function and mental health in patients with PVCs were lower than that of cases with APCs,while the score of bodily pain in patients with PVCs was higher (P value:0.0002-0.0380).In addition,the quality of life in patients with frequent PVCs were worse than healthy control(P value:0.0001-0.0915).Three months later,PVCs in 48 cases with frequent PVCs received RFCA were much fewer than that of 72 cases with drug therapy (t=18.8682,P＜0.01),and the quality of life in the former was much better than the latter (F=15.329-39.274,P＜0.01).Conclusion Frequent PVCs can deteriorate the patients' quality of life.RFCA can control or eliminate PVCs in these patients and markedly improve the quality of life of them.
