AIM To assessed the effect of liver cirrhosis(LC) on the poorly understood long-term mortality risk after firstever mechanical ventilation(1-MV) for acute respiratory *** All patients in Taiwan given a 1-MV between 1997 and 2013 were identified in Taiwan's Longitudinal Health Insurance Database 2000. Each patient with LC was individually matched, using a propensity-score method, to two patients without LC. The primary outcome was death after a *** A total of 16653 patients were enrolled: 5551 LC-positive (LC^([Pos])) patients, including 1732 with cryptogenic LCs and 11102 LC-negative(LC^([Pos])) controls. LC^([Pos]) patients had more organ failures and were more likely to be admitted to medical department than were LC^([Pos]) controls. LC^([Pos]) patients had a significantly lower survival rate(AHR = 1.38, 95%CI: 1.32-1.44). Moreover, the mortality risk was significantly higher for patients with non-cryptogenic LC than for patients with cryptogenic LC(AHR = 1.43, 95%CI: 1.32-1.54) and patients without LC(AHR = 1.56, 95%CI: 1.32-1.54). However, there was no significant difference between patients with cryptogenic and without LC(HR = 1.05, 95%CI: 0.98-1.12).CONCLUSION LC, especially non-cryptogenic LC, significantly increases the risk of death after a 1-MV.

BACKGROUND： Sarcopenia and non-alcoholic fatty liver dis- ease （NAFLD） share similar pathophysiological mechanisms, and the relationship between sarcopenia and NAFLD has been recently investigated. The study investigated whether low skel- etal muscle mass is differentially associated with NAFLD by gender in Korean adults. METHODS： We conducted a cross-sectional analysis of the data from the Fifth Korea National Health and Nutrition Examination Survey. The skeletal muscle index （SMI） was obtained by the appendicular skeletal muscle mass divided by the weight. NAFLD was defined as a fatty liver index （FLI）〉60 in the absence of other chronic liver disease. RESULTS： Among the included subjects, 18.3% （SE： 1.4%） in men and 7.0% （SE： 0.7%） in women were classified as having FLI-defined NAFLD. Most of the risk factors for FLI-defined NAFLD showed a significant negative correlation with the SMI in both genders. Multiple logistic regression analysis showed that low SMI was associated with FLI-defined NAFLD, inde- pendent of other metabolic and lifestyle parameters in both genders [males： odds ratio （OR）=1.35; 95% confidence inter- val （CI）： 1.17-1.54; females： OR=1.36; 95% CI： 1.18-1.55]. The magnitude of the association between FLI-defined NAFLD and low SMI was higher in middle aged to elderly males （OR-1.50; 95% CI： 1.22-1.84） than in males less than 45 years of age （OR=1.25; 95% CI： 1.02-1.52） and in premenopausal females （OR=l.50; 95% CI： 1.12-2.03） than in postmenopausal females （OR-1.36; 95% CI： 1.20-1.54）.CONCLUSIONS： Low SMI is associated with the risk of FLI- defined NAFLD independent of other well-known metabolic risk factors in both genders. This association may differ ac- cording to age group or menopausal status. Further studies are warranted to confirm this relationship.

Impairment of dopamine function, which is known to have major effects on behaviors and cognition, is one of the main problems associated with cerebral ischemia. Tadalafil, a long-acting phosphodiesterase type-5 inhibitor, is known to ameliorate neurologic impairment induced by brain injury, but not in dopaminergic regions. We investigated the neuroprotective effects of treatment with tadalafil on cyclic guanosine monophosphate level and dopamine function following cerebral ischemia. Forty adult Mongolian gerbils were randomly and evenly divided into five groups （n = 8 in each group）： Sham-operation group, cerebral ischemia-induced and 0, 0.1, 1, and 10 mg/kg tadalafil-treated groups, respectively. Tadalafil dissolved in distilled water was administered orally for 7 consecutive days, starting 1 day after surgery. Cyclic guanosine monophosphate assay and immunohistochemistry were performed for thyrosine hydroxylase expression and western blot analysis for dopamine D2 receptor expression. A decrease in cyclic guanosine monophosphate level following cerebral ischemia was found with an increase in thyrosine hydroxylase activity and a decrease in dopamine D2 receptor expression in the striatum and substantia nigra region. However, treatment with tadalafil increased cyclic guanosine monophosphate expression, suppressed thyrosine hydroxylase expression and increased dopamine 92 receptor expression in the striatum and substantia nigra region in a dose-dependent manner. Tadalafil might ameliorate cerebral ischemia-induced dopaminergic neuron injury. Therefore, tadalafil has the potential as a new neuroprotective treatment strategy for cerebral ischemic injury.
