摘要:

Obstructive sleep apnea syndrome (OSAS) increases the risk of post-surgery complications. This study uses Berlin Questionnaire (BQ) to identify Chinese adult surgical patients who are at a high risk of OSAS and to determine if the BQ could be used to detect potential high risk of adverse respiratory events in the post anesthesia care unit (PACU). Results indicated that only 11.4% of the patients were considered at a high risk of OSAS. Age and body mass index are the key factors for the risk of OSAS prevalence in China and also gender specific. Furthermore, the incidence of adverse respiratory events in the PACU was higher in patients with high risk of OSAS than others (6.8% vs. 0.9%, <0.001). They also stayed longer than others in the PACU (95±28 min vs. 62±19 min, <0.001). Age, high risk for OSAS, and smoking were independent risk factors for the occurrence of adverse respiratory events in the PACU. The BQ may be adopted as a screening tool for anesthesiologists in China to identify patients who are at high risk of OSAS and determine the potential risk of developing postoperative respiratory complications in the PACU.

摘要:

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality throughout the world and is mainly characterized by persistent airflow limitation. Given that multiple systems other than the lung can be impaired in COPD patients, the traditional FEV1/FVC ratio shows many limitations in COPD diagnosis and assessment. Certain heterogeneities are found in terms of clinical manifestations, physiology, imaging findings, and inflammatory reactions in COPD patients; thus, phenotyping can provide effective information for the prognosis and treatment. However, phenotypes are often based on symptoms or pathophysiological impairments in late-stage COPD, and the role of phenotypes in COPD prevention and early diagnosis remains unclear. This shortcoming may be overcome by the potential genotypes defined by the heterogeneities in certain genes. This review briefly describes the heterogeneity of COPD, with focus on recent advances in the correlations between genotypes and phenotypes. The potential roles of these genotypes and phenotypes in the molecular mechanisms and management of COPD are also elucidated.

Interactions between remote ischemic conditioning and post-stroke sleep regulation

《医学前沿(英文)》 2021年 第15卷 第6期   页码 867-876 doi: 10.1007/s11684-021-0887-9

摘要: Sleep disturbances are common in patients with stroke, and sleep quality has a critical role in the onset and outcome of stroke. Poor sleep exacerbates neurological injury, impedes nerve regeneration, and elicits serious complications. Thus, exploring a therapy suitable for patients with stroke and sleep disturbances is imperative. As a multi-targeted nonpharmacological intervention, remote ischemic conditioning can reduce the ischemic size of the brain, improve the functional outcome of stroke, and increase sleep duration. Preclinical/clinical evidence showed that this method can inhibit the inflammatory response, mediate the signal transductions of adenosine, activate the efferents of the vagal nerve, and reset the circadian clocks, all of which are involved in sleep regulation. In particular, cytokines tumor necrosis factor α (TNFα) and adenosine are sleep factors, and electrical vagal nerve stimulation can improve insomnia. On the basis of the common mechanisms of remote ischemic conditioning and sleep regulation, a causal relationship was proposed between remote ischemic conditioning and post-stroke sleep quality.

摘要: The aim of this research was to investigate the effects of modafinil, a new wake-promoting agent, on vestibular function during 24 h sleep deprivation (SD) so as to provide experimental evidence for the rational use of this drug among air crew. Eight young, healthy male volunteers were exposed to two 24 h periods of continuous wakefulness during the crossover experiment. Initially, 200 mg dose of modafinil was given, and one week later, a matching placebo was administered. The SD time started from 08:00 of the first day to 08:00 of the second day. Drugs were given at 0:00 on the second day. Vestibular function was tested at 21:00 on the first day and 1, 3, 5, 7 h after drug administration. The accuracy of saccade tracking and gains in visual-vestibular optokinetic reflex (VVOR) and optokinetic nystagmus (OKN) in the placebo group decreased during 24 h SD, especially at 01:00 05:00 on the second day, while OKN gains in the modafinil group increased significantly. There were no significant differences in the other vestibular functional indices between the modafinil group and placebo group. The 24 h SD can influence vestibular function to a certain degree, but modafinil may improve OKN.

摘要: The aim of this article was to study the influence of immunity function of advanced malignant obstructive jaundice (MOJ) treated by percutaneous transhepatic biliary external and internal drainage. Ninety-six cases of MOJ were divided into two groups according to the different ways of biliary drainage. Fifty-two external drainage tubes were placed in 41 cases of percutaneous transhepatic biliary external drainage group and 66 metal stents were placed in 55 cases of percutaneous transhepatic biliary internal drainage group. Liver function, serum TNF- and cellular function were examined one day before operation and one week after operation and liver function was re-examined two weeks after operation, in order to observe the change and analyze the asso ciation among them and compare with the control group. All patients conditions were improved after operation. In the percutaneous transhepatic biliary external and internal drainage groups, the total level of bilirubin decreased from (343.54±105.56) μ mol/L and (321.19±110.50) μ mol/L to (290.56±103.46) μ mol/L and (283.72±104.95) μ mol/L after operation respectively, which were significantly lower than pre-operation (<0.05), but there was no significant difference between the two groups (>0.05). Serum alanine aminotransferase (ALT) of all patients one week after operation was significantly lower than that before operation. TNF- in percutaneous transhepatic biliary external and internal groups decreased from (108.58±19.95) pg/mL, (109.98±16.24) pg/mL of pre-operation to (104.32±19.59) pg/mL, (83.92±13.43) pg/mL of post-operation respectively, there was notable improvement (<0.01) in internal drainage group after operation. Patients serum CD4, CD3 and CD4/CD8 were notably increased, but CD8 was notably decreased (<0.05). There was no difference in external drainage group (>0.05). There was a significant difference between the two groups. Serum TNF- and ALT had positive correlation. Percutaneous transhepatic biliary internal or external drainage was an effective and important method to treat MOJ. Patients immune function was weak when they suffered MOJ, but body s cellular immune function can be notably improved after internal biliary drainage.

摘要:

This study aimed to evaluate the efficacy of comprehensive therapy based on traditional Chinese medicine (TCM) patterns on older patients with chronic obstructive pulmonary disease (COPD) through a four-center, open-label, randomized controlled trial. Patients were divided into the trial group treated using conventional western medicine and Bu-Fei Jian-Pi granules, Bu-Fei Yi-Shen granules, and Yi-Qi Zi-Shen granules based on TCM patterns respectively; and the control group treated using conventional western medicine. A total of 136 patients≥65 years completed the study, with 63 patients comprising the trial group and 73 comprising the control group. After the six-month treatment and the 12-month follow-up period, significant differences were observed between the trial and control groups in the following aspects: frequency of acute exacerbation (P≤0.040), duration of acute exacerbation (P = 0.034), symptoms (P≤0.034), 6-min walking distance (6MWD) (P≤0.039), dyspnea scale (P≤0.036); physical domain (P≤0.019), psychological domain (P≤0.033), social domain (P≤0.020), and environmental domain (P≤0.044) of the WHOQOL-BREF questionnaire; and daily living ability domain (P≤0.007), social activity domain (P≤0.018), depression symptoms domain (P≤0.025), and anxiety symptoms domain (P≤0.037) of the COPD-QOL. No differences were observed between the trial and control groups with regard to FVC, FEV1, and FEV1%.
