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.
摘要:目的: 評價機械通氣對胸腔內脈搏氧飽和度的影響。 方法 :以食道、氣管和降主動脈作為胸腔內脈搏氧飽和度的監測位點,將改制后的氧飽和度探頭分別固定于上述部位,并連接于同一監護儀上。純氧通氣,待上述氧飽和度容積波波形和讀數穩定,停止機械通氣30s。以錄像的方式記錄機械通氣停止前后30 s內食道、氣管和降主動脈SpO2容積波和讀數的變化。同時記錄舌SpO2。 結果 :機械通氣時,食道、氣管和降主動脈三個監測位點均可獲得異常高大的SpO2容積波;停止通氣時,異常高大的氧飽和度波形消失。食道、氣管和降主動脈脈搏容積波變異率分別為112%,74%,302%。降主動脈脈搏容積波的變異率明顯高于食道和氣管( 〖WTBX〗P ＜005)。機械通氣停止前后30s內食道、氣管和降主動脈的SpO2讀數變化無顯著差異(〖WTBX〗P ＞005)。 結論 :機械通氣對胸腔內食道、氣管和降主動脈氧飽和度讀數無影響,主要影響是脈搏容積波。且各位點間脈搏氧容積波受呼吸的影響不同。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.

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.
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.
ObjectiveTo observe the efficacy of dense ligation and non-dense ligation in treating severe esophageal varices.
MethodsSixty cirrhotic patients with severe esophageal varices treated in our hospital between January 2009 and October 2011 were divided into two groups based on their operative ways.Group A was the dense ligation group including 32 patients,and group B was non-dense ligation group in which there were 28 patients.Six-shooter multi-band ligators were used for endoscopy.If the number of loop ligature collar was larger than six,it was regarded as dense ligation and the rest was regarded as non-dense ligation.
ResultsIn group A,one month after first ligature,six patients were basically cured,24 were greatly improved,and two did not respond to the treatment,with a total effective rate of 93.8% and an average ligation of 1.94 times.In group B,one month after first ligature,one patient was basically cured,24 were greatly improved,and three did not respond to the treatment,with a total effective rate of 89.3% and an average ligation of 2.75 times.
ConclusionDense ligation is a safe,reliable and effective approach for esophageal varices,which brings about a high disappearance rate of esophageal varices and reduced ligation frequency.
ObjectiveTo investigate the effects of esophageal cooling (EC) on lung injury and systemic inflammatory response after cardiopulmonary resuscitation in swine.MethodsThirty-two domestic male white pigs were randomly divided into sham group (S group, n=5), normothermia group (NT group, n=9), surface cooling group (SC group, n=9), and EC group (n=9). The animals in the S group only experienced the animal preparation. The animal model was established by 8 min of ventricular fibrillation and then 5 min of cardiopulmonary resuscitation in the other three groups. A normal temperature of (38.0±0.5)℃ was maintained by surface blanket throughout the experiment in the S and NT groups. At 5 min after resuscitation, therapeutic hypothermia was implemented via surface blanket or EC catheter to reach a target temperature of 33℃, and then maintained until 24 h post resuscitation, and followed by a rewarming rate of 1℃/h for 5 h in the SC and EC groups. At 1, 6, 12, 24 and 30 h after resuscitation, the values of extra-vascular lung water index (ELWI) and pulmonary vascular permeability index (PVPI) were measured, and meanwhile arterial blood samples were collected to measure the values of oxygenation index (OI) and venous blood samples were collected to measure the serum levels of tumor necrosis factor-α (TNF-α) and inerleukin-6 (IL-6). At 30 h after resuscitation, the animals were euthanized, and then the lung tissue contents of TNF-α, IL-6 and malondialdehyde, and the activities of superoxide dismutase (SOD) were detected.ResultsAfter resuscitation, the induction of hypothermia was significantly faster in the EC group than that in the SC group (2.8 vs. 1.5℃/h, P<0.05), and then its maintenance and rewarming were equally achieved in the two groups. The values of ELWI and PVPI significantly decreased and the values of OI significantly increased from 6 h after resuscitation in the EC group and from 12 h after resuscitation in the SC group compared with the NT group (all P<0.05). Additionally, the values of ELWI and PVPI were significantly lower and the values of OI were significantly higher from 12 h after resuscitation in the EC group than those in the SC group [ELWI: (13.4±3.1) vs. (16.8±2.7) mL/kg at 12 h, (12.4±3.0) vs. (16.0±3.6) mL/kg at 24 h, (11.1±2.4) vs. (13.9±1.9) mL/kg at 30 h; PVPI: 3.7±0.9 vs. 5.0±1.1 at 12 h, 3.4±0.8 vs. 4.6±1.0 at 24 h, 3.1±0.7 vs. 4.2±0.7 at 30 h; OI: (470±41) vs. (417±42) mm Hg (1 mm Hg=0.133 kPa) at 12 h, (462±39) vs. (407±36) mm Hg at 24 h, (438±60) vs. (380±33) mm Hg at 30 h; all P<0.05]. The serum levels of TNF-α and IL-6 significantly decreased from 6 h after resuscitation in the SC and EC groups compared with the NT group (all P<0.05). Additionally, the serum levels of IL-6 from 6 h after resuscitation and the serum levels of TNF-α from 12 h after resuscitation were significantly lower in the EC group than those in the SC group [IL-6: (299±23) vs. (329±30) pg/mL at 6 h, (336±35) vs. (375±30) pg/mL at 12 h, (297±29) vs. (339±36) pg/mL at 24 h, (255±20) vs. (297±33) pg/mL at 30 h; TNF-α: (519±46) vs. (572±49) pg/mL at 12 h, (477±77) vs. (570±64) pg/mL at 24 h, (436±49) vs. (509±51) pg/mL at 30 h; all P<0.05]. The contents of TNF-α, IL-6, and malondialdehyde significantly decreased and the activities of SOD significantly increased in the SC and EC groups compared with the NT group (all P<0.05). Additionally, lung inflammation and oxidative stress were further significantly alleviated in the EC group compared with the SC group [TNF-α: (557±155) vs. (782±154) pg/mg prot; IL-6: (616±134) vs. (868±143) pg/mg prot; malondialdehyde: (4.95±1.53) vs. (7.53±1.77) nmol/mg prot; SOD: (3.18±0.74) vs. (2.14±1.00) U/mg prot; all P<0.05].ConclusionTherapeutic hypothermia could be rapidly induced by EC after resuscitation, and further significantly alleviated post-resuscitation lung injury and systemic inflammatory response compared with conventional surface cooling.
