睡眠呼吸暂停低通气综合征( OSAHS) 是一种常见的全身性慢性疾病, 主要表现为呼吸暂停和低通气, 反复发生低氧血症、高碳酸血症和睡眠结构紊乱, 导致白天嗜睡、情绪异常、神经认知功能障碍、心脑血管疾病等。这些异常对患者的日常生活、社会功能、工作效率及认知功能等方面都有不同程度的损害, 使患者生活质量明显下降。多项研究提示 OSAHS患者生活质量与抑郁、白天嗜睡、社会支持等密切相关, OSAHS 相关的生活质量评估量表不仅能关注多导睡眠图( PSG) 无法反映的主观症状如嗜睡、困倦等, 而且反映OSAHS 导致的器官功能损害及其严重程度。本文主要就用于评价OSAHS患者生活质量主要的相关量表及其应用, 以及目前一些治疗措施对生活质量的影响作一综述。
Objective To review the complex situation，surgical experience，and surgical technique of laparoscopic cholecystectomy （LC）．Methods The clinical data of 86 patients who underwent LC in our hospital and the consulting hospitals from February 2005 to April 2011 were retrospectively analyzed．According to the complicated conditions，the different surgical techniques were applied during LC such as lamellar dissection，aspirater stripping method，laparoscopic suture，and intraoperative cholangiography．Results The operation time was （68±23）min （25－210 min），blood loss was （55±13）ml （15－200 ml）．LC was successfully performed in 84 of 86 cases．Only two patients received transferring laparotomy because of scar tissue in Calot triangle that was hard to dissect．No severe complications occurred，such as biliary leakage，bleeding after operation，stricture of bile duct，retained calculus，and so on．All the patients were cured before discharge．Conclusion Lamellar dissection，aspirater stripping method，and laparoscopic suture combined with the view of laparotomy can be used to deal with complicated LC successfully．
Objective To investigate the changes and clinical significance of cytokines and inflammatory species in exhaled breath condensate (EBC) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods Thirty AECOPD patients admitted in the Department of Respiratory Medicine from March 2015 to August 2016 (smokers and passive smokers) and 21 healthy volunteers (non-smokers) were recruited in this prospective study. General information and EBC were collected from each subject. The concentrations of interleukin-17 (IL-17), IL-10, and 8-isoprestane (8-iso-PG) in EBC were measured by enzyme-linked immunosorbent assay, meanwhile lung function test was performed in the AECOPD patients. Results Both IL-17 (ng/L) and 8-iso-PG (ng/L) levels increased significantly in the AECOPD patients before and after treatment compared with the healthy controls (10.74±1.02 and 5.65±0.88 vs. 3.36±0.61, 12.35±2.25 and 9.65±1.22 vs. 6.93±1.15, P<0.05). However, IL-10 level significantly decreased in the AECOPD patients before and after treatment compared with the healthy controls (1.68±0.17 and 2.59±0.31 vs. 2.85±0.43, P<0.05). Both IL-17 and 8-iso-PG levels in the AECOPD patients were significantly lower after treatment than those before treatment (5.65±0.88 vs. 10.74±1.02, 9.65±1.22 vs. 12.35±2.25, P<0.05), but IL-10 level were significantly higher aftertreatment than those before treatment (2.59±0.31 vs. 1.68±0.17, P<0.05). FEV1, FVC, and FEV1%pred improved significantly after treatment (P<0.01). FEV1, FEV1/FVC and FEV1%pred were not significantly correlated with IL-17, IL-10 or 8-is-PG levels. Conclusion IL-17, IL-10 and 8-iso-PG may be involved in the pathogenesis of COPD, and may be important biomarkers in monitoring airway inflammation and oxide stress during the treatment of AECOPD patients.
ObjectiveTo investigate the role of interleukin-25 (IL-25) and its receptor during allergen challenge test in allergic asthmatics as well as its underlining mechanism.MethodsFifteen allergic asthmatic patients with dual response in allergen challenge test were enrolled and blood samples were collected before and after challenge test. The expression levels of IL-25 receptor on the surface of eosinophils, plasma and intracellular IL-25 levels were measured by flow cytometry and enzyme-linked immunosorbent assay. Besides, the function of eosinophils from these patients was evaluated through the expression of type 2 cytokines, degranulation and chemotaxis after stimulation with IL-25.ResultsUpon allergen challenge, the expression of IL-17RB on the surface of eosinophils were increased from (7 426±2 824)/106 white blood cells to (19 446±5 593)/106 white blood cells (P<0.001). The expression of IL-17RA/RB on eosinophils were significantly increased from (4 508±1 360)/106 white blood cells to (9 025±3 166)/106 white blood cells (P<0.001). The plasma level of IL-25 increased from (650±45) pg/ml to (851±43) pg/ml (7 hours after allergen challenge) and (813±56) pg/ml (24 hours after allergen challenge) (P<0.001). The intracellular IL-25 expression of eosinophils was also upregulated from (10 398±1 909)/106 white blood cells to (147 684±46 222)/106 white blood cells (P<0.05). In vitro study, IL-25 (1 ng/ml) stimulated eosinophils for 2 hours promoted its expression of peroxidase [(12.5±4.2) ng/ml compared to control (1.26±0.4) ng/ml, P<0.05). The intracellular expression of IL-5 and IL-13 in eosinophils were also increased after stimulated by IL-25. IL-25 (1 pg/ml) stimulation compared to control could increase eosinophil migration in eotaxin [(36±3) vs. (69±5), P<0.05).ConclusionIL-25 and its receptor play a critical role in eosinophilic aggregation, activation and mobilization during allergic inflammation in allergic asthmatics.
Objective To investigate the short term and long term effects of laparoscopic gastric bypass on obesity related type 2 diabetes. Methods Twenty obese patients with type 2 diabetes underwent laparoscopic gastric bypass between Nov. 2009 and Feb. 2012 were identified in the computer database of West China Hospital of Sichuan University. All patients had short term follow-up of less than 1 year and among them 11 were with long term follow-up of 1 year or more. Body weight， body mass index （BMI）， blood glucose， glycosylated hemoglobin （HbA1c）， homeostasis model assessment of insulin resistance-insulin resistance （HOMA-IR）， blood pressure， and blood lipids were examined. Short term （＜1 year） and long term （≥1 year） remission rates of diabetes were calculated and factors which might have effects on the remission of diabetes were analyzed. Results Of patients with short term follow-up，body weight， fasting plasma glucose （FPG）， 2h plasma glucose （2hPG）， HbA1c， and HOMA-IR were reduced significantly. Among them， 18 of 20 patients （90.0%） reached the glucose and medication standards of complete remission and partial remission， 9 patients were defined as completely remitted （9/20， 45.0%）. Those accompanied with hypertension and （or） hyperlipemia were all improved clinically. The duration of diabetes， fasting and 2 h C peptide were found to be related to short term diabetes remission. Patients with long term follow-up of 1 year or more were observed to have significant reductions in body weight， FPG， 2hPG， HbA1c， and HOMA-IR as well. Hypertension and hyperlipidemia were all well controlled. The remission rate of diabetes reached 9/11 （81.8%）and those who were defined as completely remitted took a proportion of 6/11 （54.5%）. In these patients， those who did not reach the standards of complete remission had longer duration of diabetes and higher FPG when compared with those who did. No severe adverse event was found during the follow-up in either group. Most patients investigated were satisfied with the surgery.Conclusion Laparoscopic gastric bypass is effective and safe on short term and long term treatment of obesity related type 2 diabetes.
Objective To investigate the factors influencing the medication adherence among patients with diabetes signing family doctor service contract in Beijing urban areas, and provide the basis for improving the level of medication adherence. Methods A total of 320 patients with diabetes from four community health service centers in Beijing urban areas were selected to answer the questionnaires using convenient sampling from June to September 2015. Univariate analysis and binary logistic regression were used for the influencing factors analysis. Results A total of 320 questionnaires were distributed, and 317 valid questionnaires were recovered, in which the rate of high medication adherence was 54.6%. The results of logistic regression showed that the main impact factors on medication adherence were age [odds ratio (OR)=1.918, P=0.011)], degree of education (OR=2.462, P=0.008), knowledge related to diabetes (OR=1.773, P=0.027), adopting of family doctor service or not (OR=2.521, P=0.029) and social function status (P=0.003). Conclusions The family doctor service team should implement the practice of the family doctor service to ensure that the contracted residents can make full use of the family doctor services; and strengthen the follow-up and interventions for patients less aged or with low degree of education. For those with poor social function, more attention should be paid to their self-health management behavior to improve the level of patients’ compliance. As a result, the levels of blood glucose will be well controlled to reduce possibilities of complications and improve their health status and quality of life.
ObjectiveTo analyze the risk factors of new-onset postoperative atrial fibrillation (POAF) after coronary artery bypass grafting (CABG).MethodsFrom September 2011 to October 2013, 1 614 consecutive patients underwent elective coronary artery bypass grafting in Fuwai Hospital. There were 1 281 males and 333 females at average age of 60.3±8.4 years. Holter data recorded for 5 days after operation were collected and analyzed. The risk factors associated with POAF were assessed according to the baseline and intraoperative data, and the positive variables were stratified.ResultsA total of 314 patients (19.5%) developed new-onset POAF. The rate of POAF was elevating with the increase of age (P<0.001).ConclusionAge was an independent risk factor for POAF in patients undergoing elective CABG alone.
ObjectiveTo explore the value of transthoracic echocardiography (TTE) to monitor and evaluate aortic insufficiency (AI) within one year after the implantation of the left ventricular assist device (LVAD).MethodsWe retrospectively collected and analyzed the TTE data of 12 patients who received LVAD implantation from 2018 to 2020 in our hospital. All patients were males, with an average age of 43.3±8.6 years. We analyzed temporal changes in the aortic annulus (AA), aortic sinus (AoS), ascending aorta (AAo), the severity of AI and the opening of aortic valve before operation and 1 month, 3 months, 6 months and 12 months after LVAD implantation.ResultsAll 12 patients survived within 1 year after LVAD implantation. One patient was bridged to heart transplantation 6 months after implantation, and two patients did not receive TTE after 3 and 6 months. Compared to pre-implantation, AoS increased at 1 month after implantation (31.58±5.09 mm vs. 33.83±4.69 mm). The inner diameters of AA, AoS and AAo increased at 3, 6 and 12 months after LVAD implantation compared to pre-implantation (P<0.05), but all were within the normal range except for one patient whose AoS slightly increased before operation. After LVAD pump speed was adjusted, the opening of aortic valve improved. The severity of AI increased at 6 and 12 months after LVAD implantation compared to pre-implantation, and increased at 12 months compared to 6 months after LVAD implantation (P<0.05).ConclusionTTE can evaluate aortic regurgitation before and after LVAD implantation and monitor the optimization and adjustment of LVAD pump function, which has a positive impact on the prognosis after LVAD implantation.
ObjectiveTo evaluate the diagnostic accuracy and efficacy of X-ray for evaluating the tip position of umbilical venous catheterization (UVC). MethodsThe PubMed, Embase, Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect diagnostic tests for UVC tip localisation from inception to 1 May 2023. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data and assessed the quality of the studies using the QUADAS-2 tool. Then, meta-analysis was performed by using Stata 16.0 software. Results Twelve articles involving 1 055 patients were included. The sensitivity and specificity of Negar Yazdani’s study were both 100%. The results of the meta-analysis (the remaining eleven articles, n=951) indicated a pooled sensitivity of 0.7 (95%CI 0.6 to 0.8), a pooled specificity of 0.8 (95%CI 0.7 to 0.9), a positive likelihood ratio of 4.0 (95%CI 2.0 to 8.1), a negative likelihood ratio of 0.4 (95%CI 0.2 to 0.6) and a diagnostic odds ratio of 11 (95%CI 3 to 36) with an area under the cumulative receiver operating characteristic curve of 0.8 (95%CI 0.8 to 0.9). A subgroup analysis was performed according to the different methods of judging X, the 8th–9th thoracic, the 9th–10th thoracic and combined judgement of the diaphragmatic plane + the vertebral body + the heart shadow. The sensitivities of the 3 groups were 0.8 (95%CI 0.5 to 0.9), 0.5 (95%CI 0.4 to 0.7) and 0.8 (95%CI 0.6 to 0.9); the specificities of the 3 groups were 0.8 (95%CI 0.6 to 0.9), 0.76 (95%CI 0.6 to 0.9) and 0.91 (95%CI 0.79 to 0.96). The areas under the cumulative receiver operating characteristic curve were 0.9 (95%CI 0.8 to 0.9), 0.7 (95%CI 0.6 to 0.7) and 0.92 (95%CI 0.89 to 0.94). ConclusionSome error is present when determining the catheter tip position by X-ray, in which the evaluation of the umbilical vein catheter tip position through a comprehensive evaluation of the diaphragmatic plane, the heart margin and the vertebral body is more powerful than the evaluation of the vertebral body alone.
ObjectiveTo explore the risk factors for death within 7 days after admission in trauma patients undergoing surgery under general anesthesia, and provide evidence for predicting the outcomes of those patients and guidance for clinical practices.MethodsThe basic information and perioperative data of trauma patients who underwent surgery under general anesthesia between January 1st 2019 and December 31st 2020 were collected from the Hospital Information System and the Anesthesia Information Management System. Patients who died within 7 days after admission were assigned into the case group and the others were assigned into the control group, and then propensity-score matching method was used based on age, sex, and injury types. Univariate analyses and multivariate binary logistic regression analysis were used to identify the risk factors for death within 7 days after admission in these patients.ResultsThere were 2 532 patients who met the inclusion criteria, of whom 96 patients with missing follow-up information were excluded, and 2 436 patients remained for the study. After propensity-score matching, there were 19 patients in the case group and 95 patients in the control group. The result of multivariate logistic regression analysis showed that the coma state at admission [odds ratio (OR)=9.961, 95% confidence interval (CI) (1.352, 73.363), P=0.024], perioperative body temperature<36℃ [OR=23.052, 95%CI (1.523, 348.897), P=0.024], intraoperative mean arterial pressure<60 mm Hg (1 mm Hg=0.133 kPa) [OR=12.158, 95%CI (1.764, 83.813), P=0.011], serum calcium concentraion<2.0 mmol/L [OR=33.853, 95%CI (2.530, 452.963), P=0.008], and prothrombin time [OR=1.048, 95%CI (1.002, 1.096), P=0.042] increased the risk of death within 7 days after admission.ConclusionThe coma state, coagulopathy, perioperative hypothermia, intraoperative hypotension, and hypocalcemia are 5 independent risk factors for death in trauma patients after surgery under general anesthesia.
