Akin to other functional gastrointestinal disorders, research has demonstrated an association between this common diagnosis and psychosocial factors and psychiatric morbidity. Conceptualising the relevance of these factors within the syndrome of FD requires application of the biopsychosocial model of disease. Using this paradigm, dysregulation of the reciprocal communication between the brain and the gut is central to symptom generation, interpretation and exacerbation. Appreciation and understanding of the neurobiological correlates of various psychological states is also relevant. The view that psychosocial factors exert their influence in FD predominantly through motivation of health care seeking also persists. This appears too one-dimensional an assertion in light of the evidence available supporting a more intdnsic aetiological link. Evolving understanding of pathogenic mechanisms and the heterogeneous nature of the syndrome will facilitate effective management. Co-morbid psychiatric illness warrants treatment with conventional therapies. Acknowledging the relevance of psychosocial variables in FD, the degree of which is subject to vadation, has implications for assessment and management. Available evidence suggests psychological therapies may benefit FD patients particularly those with chronic symptoms. The rationale for use of psychotropic medications in FD is apparent but the evidence base to support the use of antidepressant pharmacotherapy is to date limited.展开更多

Incident delirium was diagnosed postoperatively with a structured clinical interview and patients were monitored every day post-operatively for confusion and disturbance in consciousness.Results Delirium developed in 63 persons （35% of sample）. After adjustment for covariates, delirium was significantly associated with depression [odds ratio （OR）： 1.08; 95% confidence interval （CI）： 1.03-1.13,P = 0.003], anxiety （OR： 1.07; 95% CI： 1.02-1.13,P= 0.01） and stress （OR： 1.05; 95% CI： 1.00-1.09,P= 0.03）. Preoperative depression scores were associated with poorer QOL including bodily pain （β =-0.39,P = 0.013）, vitality （β=-0.32,P = 0.020）, social functioning （β=-0.51,P≤0.001）, emotional role function （β=-0.44,P = 0.003） and general health （β=-0.33,P = 0.038）. Among the covariates, harmful levels of alcohol use was consistently associated with poorer QOL.Conclusions Depression and harmful levels of alcohol use were consistently associated with poorer QOL whereas depression, anxiety and stress were associated with delirium risk. These findings point to further research examining depression and harmful levels of alcohol use in coronary heart disease populations undergoing coronary revascularization.展开更多

Methods Fifteen symptomatic, drug-refractory patients with HOCM underwent PTSMA procedures with application of a myocardial contrast echocardiography (MCE) intra-procedure. Before and after the procedure, clinical evaluations were obtained in all patients, who were followed up for a mean period of 8.6±3.8 (6-20) months.Results Immediate left ventricular outflow tract gradient (LVOTG) reduction was achieved (77.93±22?mm?Hg vs 14.8±15?mm?Hg, P【0.0001) after the procedure with a mean decrease of 5.75±2.87?mm?Hg of left ventricular end diastolic pressure (P【0.001). Follow up results revealed that ventricular remodelling occurred mainly 1-3 months after the procedure, but without evidence of ventricular dilation and contract dysfunction. Heart function (NYHA) was greatly improved (3.4±0.5 vs 1.1±0.4, P【0.001) and exercise endurance increased. A renewed increase of LVOTG was found in 2 patients during follow-up. Conclusions LVOTG was greatly decreased in HOCM patients undergoing a PTSMA procedure, and their symptoms were greatly improved without cardiac complications during follow-up. Sub-selection and re-opening of target vessels were the causes of renewed increase of LVOTG, and this can be avoided with the accumulation of experience. This is a promising method for the treatment of symptomatic patients with HOCM.展开更多

METHODS: Seventy-two patients with symptomatic left ventricular outflow tract obstruction were diagnosed by echocardiography or catheterization procedures. Absolute ethanol was injected into the target coronary artery branch (branches) for septal myocardial ablation. Documented complications were recorded. RESULTS: Sixty-nine patients had severe chest pain, 19 developed different degrees of heart block during the periprocedural period, but only one developed a complete AV block, requiring permanent pace-maker implantation. Temporary right bundle branch block occurred in 50% of patients and permanent block occurred in 38.9% of patients. Acute inferior myocardial infarction occurred in six patients (8.3%) and acute anterior myocardial infarction occurred in one patient. During two-year follow-up of 24 cases, there were no deaths. All patients had improvement in heart function and none experienced heart failure. CONCLUSION: The most common complication of PTSMA is right bundle branch block. The most significant complication of the procedure is heart block. PTSMA is a good technical, non-surgical treatment for HOCM.展开更多

METHODS: Aticles focusing on Astragaloside IV in English and Chinese in databases were collected and reviewed in order to summarize the latest extraction separation, pharmacokinetics, and the pharmacological effects of astrageloside IV. RESULTS: Protective effects of Astrageloside IV on the cardiovascular system, immune, digestive, nervous system were identified, and the action mechanisms were associated with regulation of the calcium balance, anti-oxydant, antiapoptosis, antivirus, and so on. CONCLUSION: Astrageloside IV has broad application prospects, especially in cardiovascular diseases, digestive diseases, cancer and other modern high incidence, high-risk diseases, and could be developed as a medicine.展开更多
