Objective To investigate the prevalence and predisposing factors of gastroesophageal reflux（GER）in patients with chronic obstructive pulmonary disease（COPD）and its impacts on the frequency of COPD exacerbations.Methods 50 patients with acute exacerbation of COPD were enrolled in the study.All patients filled a modified version of clinically validated standardized Mayo Clinic GER questionnaire.Pulmonary function tests（PFT），body mass index（BMI），serum albumin，and medications were recorded.The patients were divided in to GER group（13 patients with GER symptoms longer than one year and diagnosed GER by gastroscope） and non-GER group（37 patients without GER symptoms）.Results There were no significant differences in the BMI，serum albumin，use of inhaled steroids and theophylline between the two groups.Forced expiratory volume in one second as a percentage of the predicted value（FEV1%pred）（37% vs 38.3%，P=0.608.），residual volume % predicted（123.4 % vs 137.8%，P=0.222），and residual volume to total lung capacity（139.4% vs 141.5%，P=0.798） were not significantly different between the two groups.The number of COPD exacerbations per year was significantly higher in patients with GER compared to patients without GER（4.5 vs 1.3，P=0.006）.Conclusions The severity of airflow obstruction and the hyperinflation is unlikely to contribute to the development of GER.Patients with GER experience significantly more exacerbations per year when compared to patients without GER，suggesting more highlight warrant in treatment of GER in COPD patients.
The pectoralis major myocutaneous flap was used to repair laryngopharyngeal and esophageal defect following radical excision of pharyngeal and inferior laryngeal carcinomas in 3 cases. The results were susscessful. The patients were follwedup for 6 months to 3 years. The deglutition functions were all reestablished, the general nutritional conditions were improved, and no recurrence or distant metastasis was observed. The advantages of this operative procedure were discussed.
目的:观察经鼻内镜检查引导下通过改良三腔二囊管加沙氏导丝引导支撑,结合内镜下硬化剂治疗肝硬化食管静脉曲张破裂出血的疗效。方法:14例肝硬化食道静脉曲张破裂出血患者经过经鼻内镜检查后通过改良的三腔二囊管加沙氏导丝支撑下,结合内镜下硬化剂治疗食管静脉曲张破裂出血,观察止血效果以及并发症。结果:14例患者均1次止血成功,1例患者治疗后8h再次出血,行急诊TIPSS手术治疗。主要反应为胸骨后疼痛,持续时间为2～7d,对症处理后消失,3、6个月后再次复查食道胃底曲张静脉明显改善,3例10d左右行内镜下再次硬化治疗(因第1次硬化剂量少或治疗不完全)。结论:经鼻内镜检查行改良三腔二囊管加沙氏导丝引导支撑下,结合内镜下硬化剂治疗肝硬化食管静脉曲张破裂出血是一种有效的治疗方法。
摘要:目的: 评价机械通气对胸腔内脉搏氧饱和度的影响。 方法 :以食道、气管和降主动脉作为胸腔内脉搏氧饱和度的监测位点,将改制后的氧饱和度探头分别固定于上述部位,并连接于同一监护仪上。纯氧通气,待上述氧饱和度容积波波形和读数稳定,停止机械通气30s。以录像的方式记录机械通气停止前后30 s内食道、气管和降主动脉SpO2容积波和读数的变化。同时记录舌SpO2。 结果 :机械通气时,食道、气管和降主动脉三个监测位点均可获得异常高大的SpO2容积波;停止通气时,异常高大的氧饱和度波形消失。食道、气管和降主动脉脉搏容积波变异率分别为112%,74%,302%。降主动脉脉搏容积波的变异率明显高于食道和气管( 〖WTBX〗P ＜005)。机械通气停止前后30s内食道、气管和降主动脉的SpO2读数变化无显著差异(〖WTBX〗P ＞005)。 结论 :机械通气对胸腔内食道、气管和降主动脉氧饱和度读数无影响,主要影响是脉搏容积波。且各位点间脉搏氧容积波受呼吸的影响不同。Abstract: Objective: To investigate the impact of mechanical ventilation on pulse oximetry in thoracic cavity. Methods : After dogs anesthesia induction and thoracotomy, pulse oximeters were simultaneously placed at esophagus, trachea, and descending aorta, and connected with the same monitor for SpO2 monitoring. During ventilation with 100% oxygen, the mechanical ventilator was temporarily switched off for 30 seconds after high quality PPG waveforms and SpO2 readings were obtained. SpO2 signals and readings from esophagus (SeO2), trachea (StraO2), descending aorta (SDAO2) shown on the monitoring screen were recorded by the SONY video before and after stopventilation. And StonO2 were also recorded. Results : Abnormally largeamplitude PPG waves were found in normal waves at monitoring sites of esophagus, trachea, and descending aorta in all animals during ventilation; however, they disappeared without ventilator. The variation rate in ventilationinduced PPG amplitude were 112%, 74%, 302% at esophagus, trachea and descending aorta respectively. The PPG amplitude variation rate from SDAO2 was higher than that from SeO2 and StraO2 (〖WTBX〗P ＜005). However, the SpO2 readings obtained from pulse oximetries in all sites were no significantly statistical difference within 30s before and after temporarily stopventilation (〖WTBX〗P ＞005). Conclusion : Abnormally amplitude PPG waveforms from oximetry probe placed at esophagus, trachea, and descending aorta were induced by ventilation. The Variation rate in ventilationinduced PPG amplitude was various at different monitoring sites. The SpO2 readings from esophagus, trachea, and descending aorta were not significantly contaminated by ventilation.
Surgerical treatment has been used for portal hypertension over a hundred years, and has evolved from various portosystemic shunts to devascularizations and selective shunts. Selective shunting, which has the advantages of long-term prevention from recurrent variceal bleeding and maintenance of hepatic portal vein perfusion, has developed from single distal splenorenal shunt to various procedures including distal splenocaval shunt, coronary caval shunt, coronary renal shunt, etc. Selective shunting can also be achieved after reconstruction of spontaneous portosystemic shunt. Preoperative portal venous system CT angiography, intraoperative ultrasound Doppler and portal vein pressure measurements may provide patients with a more reasonable treatment of choice.
Objective To analyze the spatiotemporal evolution characteristics of the disease burden of esophageal cancer in China from 2001 to 2021, and provide scientific evidence for optimizing public health intervention strategies. Methods Data were derived from the Global Burden of Diseases (GBD 2021) database, extracting indicators including incidence, prevalence, mortality, disability-adjusted life year (DALY) rate, and years of life lost (YLL) rate for esophageal cancer in China. The Joinpoint regression model was employed to assess long-term trends in disease burden across genders and age groups, combined with age-standardization using the GBD world standard population. Average annual percentage change (AAPC) and 95% confidence intervals (CI) were calculated, and Excel 2019 was used for data collation and descriptive statistics. Results In 2021, the crude incidence, prevalence, and mortality rates of esophageal cancer in China were 22.55, 38.37, and 20.26 per 100 000 population, respectively, representing increases of 13.49%, 23.41%, and 1.30% compared to 2001. The DALY and YLL rates were 450.14 and 436.29 per 100 000, decreasing by 18.01% and 16.10% over the same period. Significant gender disparities were observed, with males exhibiting higher age-standardized incidence, prevalence, mortality, DALY, and YLL rates than females. In 2021, the male age-standardized incidence (34.29/100 000) and mortality (31.06/100 000) rates were 3.3 and 3.5 times those of females, respectively. Disease burden increased exponentially with age, peaking in the 70 to 74-year-old group for incidence, prevalence, and DALY rates, with males showing significantly higher values than females. Trend analysis of standardized rates revealed significant declines from 2001 to 2021, with AAPC values of −2.03% for incidence, −1.42% for prevalence, −2.57% for mortality, and −2.84% for DALY rate (all P<0.05). Conclusion The age-standardized disease burden of esophageal cancer in China has decreased over the past two decades, while crude rates have continued to rise, with a pronounced burden among males and older populations. Against the backdrop of accelerating population aging, targeted early screening, behavioral interventions, and optimized resource allocation are imperative to address the challenges in preventing and controlling esophageal cancer.

Methods From November 2004 to May 2008, according to the disease condition or patient′s requirements, anesthetists assessed 13 patients who underwent conscious sedation with the intravenous injection of midazolam + fentanyl; 30 patients underwent intravenous anesthesia with intravenous injection of midazolam+propofol. Thirty-six patients underwent set tie treatment, and seven underwent 1% aethoxysklerol injection therapy. Results AN of the 43 patients completed the treatment successfully, and the emergency bleeding rate was 100% (11/11). Four weeks after the treatment, 24 cases had apparent therapeutic effect, accounting for 55.8%; 17 patients had effect, accounting for 39.5%; 2 patients had no effect; the total effective rate was 95.3%. The postoperative forgotten degree of the patients in intravenous anesthesia group was 100%. The nausea rate happened during the mirrors inserting and treatment in the conscious sedation group was 76.9% and 46.1%, respectively. No hemorrhage occurred in both of the tow groups. Conclusion Painless endoscopic is safe and effective for esophageal varices. Intravenous anesthesia should be used in Sclerotherapy.
