OBJECTIVETo compare the effects of clopidogrel combined with dihydropyridine calcium-channel blockers (CCBs) or non-dihydropyridine CCBs on coronary artery disease (CAD) in elderly patients.

METHODSThe study cohort was defined as all patients ≥60 years old hospitalized for CAD with the prescription of clopidogrel between January 2001 and February 2011. The primary endpoint was death of all causes, and the secondary endpoints were nonfatal myocardial infarction (MI), hospitalization for unstable angina, stroke, transient ischemic attack, or repeat revascularization (PCI or coronary artery bypass graft).

RESULTSA total of 1021 patients were enrolled, among whom 402 patients were prescribed with clopidogrel and 619 with clopidogrel combined with CCB (dihydropyridine in 547 and non-dihydropyridine in 72). In clopidogrel group and clopidogrel with CCB group, the incidence density of death was 50.55 per thousand and 42.02 per thousand, respectively. The crude RR was 0.83 (95%CI: 0.55-1.26), and the multivariable-adjusted RR was 0.47 (95%CI: 0.14-1.6), showing no statistical significance in the rate of deaths of call causes between the two groups (P>0.05); the incidence density of composite thromboembolic events showed no significant difference between the two groups, either (P>0.05). After weighting of the propensity score, the patients with clopidogrel coadministered with non-dihydropyridine CCB showed a significant increase in composite thromboembolic events than those taking dihydropyridine CCB, with a SMRW-adjusted OR of 1.97 (95%: 1.2-3.23, P=0.007). No significant difference was observed in death or composite thromboembolic events between Pgp-inhibiting CCBs and non-Pgp-inhibiting CCBs.

CONCLUSIONCompared with clopidogrel without CCB, clopidogrel with CCB does not increase the mortality or composite thromboembolic events in elderly CAD patients, but clopidogrel combined with non-dihydropyridine CCB is associated with significantly increased composite thromboembolic events in comparison with dihydropyridine CCB.

Amino-acid neurotransmitter system dysfunction plays a major role in the pathophysiology of depression. Several studies have demonstrated the potential of amino acids as a source of neuro-specific biomarkers could be used in future diagnosis of depression. Only partial amino acids such as glycine and asparagine were determined from certain parts of rats' brain included hippocampi and cerebral cortex in previous studies. However, according to systematic biology, amino acids in different area of brain are interacted and interrelated. Hence, the determination of 34 amino acids through entire rats' brain was conducted in this study in order to demonstrate more possibilities for biomarkers of depression by discovering other potential amino acids in more areas of rats' brain. As a result, 4 amino acids (L-aspartic acid, L-glutamine, taurine and gamma-amino-n-butyric acid) among 34 were typically identified as potentially primary biomarkers of depression by data statistics. Meanwhile, an antidepressant called Fluoxetine was employed to verify other potential amino acids which were not identified by data statistics. Eventually, we found L-alpha-amino-adipic acid could also become a new potentially secondary biomarker of depression after drug validation. In conclusion, we suggested that L-aspartic acid, L-glutamine, taurine, gamma-amino-n-butyric acid and L-alpha-amino-adipic acid might become potential biomarkers for future diagnosis of depression and development of antidepressant.

Objective:To explore the function of temperature difference stimulation oral nursing for the patients with mild to moderate dysphagia after oral cancer operation.Methods:A total of 64 patients with mild to moderate dysphagia after oral cancer surgery admitted to our hospital from January 2019 to June 2021 were selected as the research subjects by convenient sampling method, and divided into control group ( n=32) and observation group ( n=32) according to random number table method. The grouping method was random number table method. The control group was treated with traditional ice-water stimulation rehabilitation training, and the observation group was treated with temperature difference stimulation oral care. The degree of dysphagia, nutritional status, postoperative complications and quality of life were analyzed and compared between the two groups. Results:After the intervention, the degree of dysphagia in the observation group (water swallow test) fromⅠto Ⅳ degree were 2, 11, 13 and 6 cases, while in the control group were 9, 17, 4 and 2 cases, the difference was significant ( Z=-3.41, P<0.05). After the intervention, the serum albumin of the observation group was (38.74 ± 4.87) g/L, which was significantly higher than that of the control group (35.81 ± 5.14) g/L. there was significant difference between the two groups ( t=2.34, P<0.05). After the intervention, the self scores of chewing, swallowing, anxiety, emotion and quality of life in the Chinese version of the University of Washington quality of life scale in the observation group were 70.28 ± 10.39, 68.20 ± 9.43, 72.39 ± 12.28, 65.30 ± 15.33 and 78.05 ± 9.47, which were significantly higher than those in the control group 64.29 ± 9.26, 61.42 ± 12.38, 64.50 ± 10.43, 58.08 ± 11.62 and 72.92 ± 10.40, The difference was statistically significant ( t values were 2.06-2.77, all P<0.05). Conclusions:Oral nursing with temperature difference stimulation can effectively improve the swallowing disorder of patients after oral cancer surgery, reduce the incidence of aspiration and malnutrition, and improve the quality of life of patients.
