Esophageal cancer is the leading cause of cancer-related deaths worldwide.A single intraoperative intervention is unlikely to benefit the outcome.A multimodal management plan that includes the use of TEA seems to demonstrate improved results in high-volume centers.Anesthetic management may contribute to the containment of pulmonary morbidity and anastomotic leakage by the use of TEA,protective ventilation strategies during OLV,prevention of tracheal aspiration,and judicious fluid management.

ObjectiveTo explore the effects of Yiqi Yangyin Huoxue principle on the expression of neurotrophin-3 of the frontal lobe cortex neurons in diabetic rat brain. Methods The diabetic rat model was produced by intraperitoneal injection of streptozotocin(STZ).The Yiqi Yangyin Huoxue drugs was poured into the stomach of the treated group. The brains were taken and the expression of neurotrophin-3 was estimated with immunochemistry 8 weeks later. Results Immunochemistry showed that there were many positive cells in the frontal lobe cortex of the normal group and they were deeply dyed.Positive cells of the model group decreased and their color was shallow .The number and the color of positive cells in the treated group were close to that of the normal group. Conclusion The Yiqi Yangyin Huoxue principle can effectively improve the degenerating of the frontal lobe cortex neurons in diabetic rat brain.

Objective To investigate the effect of Buyanghuanwu decoction(BYHWD) on angiogenesis and Ang-1/Tie-2 expression after focal cerebral ischemia in mice. Methods Focal cerebral ischemia was induced by 30 min of middle cerebral artery occlusion followed by reperfusion. BYHWD (20 g/kg) was administered orally 24 h after ischemia and once a day. The neurological score and the corner test were used to evaluate sensorimotor function during 28 days after ischemia. The microvessels density and the expression of Ang-1/Tie-2 in the ischemic boundary zone were determined by immunohistochemistry on 28 days after ischemia. Results Compared with the model group, BYHWD significantly ameliorated neurological dysfunction and reduced the number of right turn during 3 to 28 days after ischemia(P＜0.05 ). In addition,the numbers of CD31 ,Ang-1 and Tie-2 immunopositive cells were (437 ±59) ,(389 ±61 ) and (251 ±42) at the boundary zone in model group 28 days after ischemia,respectively. However, BYHWD treatment significantly increased the numbers of CD31(609 ± 68 ), Ang-1 (551 ±66) and Tie-2 (342 ±46) immunopositive cells(P＜0. 01 ). Conclusion BYHWD promotes angiogenesis,which may contribute to recovery of neurological function after focal cerebral ischemia,and Ang-1/Tie-2 pathway appears to mediate BYHWD-induced angiogenesis.

Objective To explore the value of cardiac troponin-I (cTnI), B-type natriuretic peptide (BNP) and blood lactic acid (Lac) on evaluation of severity and prognosis in patients with septic myocardial dysfunction (SMD). Methods According to retrospective analysis of clinical data,161 cases with sepsis were divided in to SMD group and non-SMD group. And the SMD group was further divided in to death group and survival group. Blood cTnI, BNP and Lac value in each group were detected respectively. The ROC curve was used to evaluate the forecast value of cTnI, BNP and Lac on prognosis for patients. Results The value of cTnI, BNP and Lac in SMD group were significantly higher than those in non-SMD group(P<0.05);The value of cTnI, BNP and Lac in death group among the SMD patients were significantly higher than those in survival group(P<0.05);cTnI, BNP and Lac contribute to predict the 28 day mortality rate of SMD. Conclusions Blood cTnI, BNP and Lac contributes to the assessment of the severity and the prognosis of septic patients with myocardial dysfunction.

Objective To evaluate the effects of edaravone on postoperative delirium in aged patients following total hip -re-placement surgery . Methods Two hundred and forty-six patients undergoing unilateral hip replacement surgery were randomly divided into edaravone group and control group .Patients in the edaravone group were intravenous injected with edaravone 30 mg before anesthesia induction, whereas patients in the control group received the same volume of saline solution .On preoperative day 1 and postoperative day 1, confusion assessment was applied to evaluate the consciousness of patients .The length of hospital stay , incidence of myocardial infarc-tion, stroke, pulmonary embolism, pneumonia and transfusion volume were also recorded .Also, the levels of plasma malondialdehyde ( MDA) superoxide dismutase ( SOD) , neuron-specific enolase ( NSE) and S100βprotein ( S100β) were measured on the preoperative and postoperative day 1. Results There was no difference in the length of hospital stay , the incidence of perioperative acute pulmonary embolism, myocardial infarction and stroke (P>0.05).POD was significantly lower in the edaravone group than the control group (P<0.05).Plasma levels of MDA, SOD, NSE and S100βwere comparable between the two groups (P>0.05).On the postoperative day 1, plasma levels of MDA and NSE were significantly lower in the edaravone group than the control group (P<0.05). Conclusion Edar-avone can reduce the incidence of POD in aged patients following total hip-replacement surgery .

Objective To investigate the relationship between the activity of Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway in cerulein-induced pancreatic acinar cell line AR42J. Methods The in vivo model of AP was induced by cerulean treated pancreatic acinar cell line AR42J, then RPM and AG490 were given for intervention. Western blot was used to determine theexpressions of JAK1 and phosphorylation JAK1 ( P JAK1 ) , STAT1, PSTAT1 and TNFα, IL-1β, IL-6. The expressions of IL-6, IL-1 β, and TNFα mRNA were measured by RT-PCR. Survival rate of cells was evaluated by trypan blue stain. Results The relative expressions of JAK1, P JAK1, STAT1, P STAT1 and TNF-o, IL-1β, IL 6 without cerulean treatment were 0.09 ±0.04,0.14 ±0.08,0.21 ±0.09,0.12 ±0.12,0.10 ±0.02,0.08 ± 0.03,0.02 ± 0.02. After cerulean treatment, the expressions of abovementioned protein increased in a time-dependant manner, the expressions at 24h were 0.53 ± 0.09,0.53 ± 0.13,0.56 ± 0.09,0.55 ± 0.10,0.25 ± 0.04,0.25 ±0.09,0.27 ±0.07, which were significantly higher than those in the control group (P ＜0.05). 2 4 h after RPM and AG 4 9 0 inhibition, the expressions of TNF-α, IL-1 β, IL-6 proteins significantly decreased to 0.17 ± 0.03and 0.17 ± 0.01,0.15 ± 0.05 and 0.14 ± 0.07,0.19 ± 0.04 and 0.19 ± 0.05; their expressions of mRNA significantly decreased ( P ＜ 0.05 ). The cell survival rates in RPM and AG490 treatment group were (72.4 ± 11.2) %, (69.7 ± 9.8 ) %, and in cerulein-stimulated cells (42.2 ± 12.3 ) % ( P ＜ 0.05 ).Conclusions The JAK1/STAT1 signaling pathway was involved in pancreatic inflammatory response with cerulein stimulation. Early treatment with inhibitors to the JAK1/STAT1 signaling pathway might control the inflammatory response in acute pancreatitis.

Objective:To analyze and compare clinical characteristics and risk factors of patients with uremic encephalopathy (UE).Methods:A retrospective analysis was performed from January 2014 to January 2019 in our hospital. Seventy patients diagnosed with chronic kidney disease (CKD) at the end stage (according to diagnosis standard of CKD) complicated with UE were classified into the UE group. In principle matching with sex, age and duration of disease, seventy patients with chronic kidney disease at the end stage but without UE were classified into the non-UE group (NUE group). The demographic data, laboratory examination, CT or MRI examination were recorded and analyzed by using t or χ 2 test. In addition, independent risk factors of patients with UE were analyzed by using Logistic model. Results:A total of 70 patients in the UE group and 70 patients in the NUE group were collected. The proportion of patients with a history of alcohol comsumption, chronic obstructive pulmonary disease and polycystic kidney disease were higher in the UE group than in the NUE group ( P<0.05). There were no significant differences in hypertension, diabetes, and coronary artery disease history between the two groups ( P>0.05). The proportion of cerebral focus and lesions for brain white matter revealed by head CT or MRI in the UE group were significantly higher than that in the NUE group ( P<0.05). The serum NLR and UA levels in the UE group were higher than those in the NUE group ( P<0.05), but the serum ALB and FT3 levels in the UE group were lower than those in the NUE group ( P<0.05). Logistic regression analysis showed that serum NLR, ALB and FT3 levels were independent risk factors for UE patients. Conclusions:Cerebral focus and lesions for brain white matter revealed by CT or MRI are typical abnormal in UE patients. The serum NLR, FT3 and ALB levels are independent risk factor for UE patients.
