The concept of "spirit" in traditional Chinese medicine （TCM） aligns closely with "the liver governs the designing of strategy". By exploring the relationship between the liver and executive function decline， it is proposed that prolonged liver constraint leads to indecisiveness in strategy designing， which is the initiating factor for executive function decline； liver blood deficiency causes difficulties in executing strategy， which forms an essential foundation for the progression of executive function decline； obstruction in the "liver-du mai-brain" pathway leads to unclear strategy designing， which accelerates executive function decline. This relationship is examined from the perspectives of TCM， modern medicine， and cognitive psychology， aiming to provide insights into addressing executive function decline through treatments focused on the liver.

Objective:To analyze the local recurrence patterns after concurrent chemoradiotherapy (CCRT) for thoracic esophageal squamous cell carcinoma (ESCC) through image fusion, and to explore the risk factors of local recurrence and its relationships with dosimetric indices.Methods:A retrospective analysis was conducted for 209 thoracic ESCC patients who received radical CCRT in Fourth Hospital of Hebei Medical University during 2016-2019. For the patients diagnosed as the local recurrence of esophageal lesions, their CT images were fused with the original planning CT images using image registration software to identify the recurrence sites. Through 1∶1 propensity score matching (PSM) of the clinal data of patients with local recurrence (the recurrence group, nbefore = 81, nafter = 62) and those without local recurrence (the recurrence-free group, nbefore = 128, nafter=62), the dose and volume parameters of the treatment plans for the two groups were compared. Univariate and multivariate analyses were conducted using the Kaplan-Meier method and the Cox regression model to analyze the factors affecting the overall survival (OS), progression-free survival (PFS), and recurrence-free survival (RFS). Results:All patients had 1-, 3-, and 5-year OS rates of 80.9%, 42.6%, and 33.0%, respectively, 1-, 3-, and 5-year PFS rates of 67.9%, 34.0%, and 27.9%, respectively, and 1-, 3-, and 5-year RFS rates of 71.3%, 39.2%, and 30.5%, respectively. T stage, N stage, and radiation dose were independent prognostic factors for the OS, PFS, and RFS ( HR = 1.42-1.87, P < 0.05) of the patients, respectively. Among 68 patients with local recurrence, 62 cases (91.2%) suffered recurrence within the gross tumor volume (GTV). The dose and volume parameters of patients with local recurrence, such as GTV- D95%, clinical target volume (CTV)- D95%, GTV- D50%, CTV- D50%, and planning target volume (PTV)- D50%, GTV- V60, CTV- V60, and PTV- V60, were significantly lower than those of patients free from the local recurrence ( t=1.90-2.15, P < 0.05). Conclusions:Local recurrence of patients with thoracic ESCC after radical CCRT occurs mainly within the GTV. Increasing radiation doses may contribute to their survival benefits. The D50% for each target volume in the radiotherapy plan may be related to local recurrence, and it is necessary to conduct further research.

Objective:To compare the efficacy of HES 130/0.4 and acetate Ringer′s solution (A-HES) and HES 130/0.4 and normal saline (NS-HES) for volume therapy in the patients undergoing non-cardiac surgery with general anesthesia.Methods:Two hundred and fifty American Society of Anesthesiologist physical status Ⅰ or Ⅱ patients of both sexes, aged 18-64 yr, with body mass index of 18-32 kg/m 2, undergoing noncardiac surgery with general anesthesia, were divided into group A-HES and group NS-HES using the stratified block randomization technique.A-HES and NS-HES 15 ml/kg were intravenously infused over 1 h immediately after induction of anesthesia in A-HES and NS-HES groups, respectively.Mean arterial pressure (MAP), heart rate (HR) and central venous pressure (CVP) were recorded before and after infusion, and the maximum changing rate of MAP and HR and the maximum change in CVP were calculated.The pH value, BE and HCO 3- were recorded before infusion and at 15 min after the end of infusion, and Hb, Hct, electrolytes, blood glucose, blood biochemical parameters and parameters of coagulation function were measured.The occurrence of abnormal blood biochemical parameters, blood glucose, and parameters of coagulation function, intraoperative requirement for vasoactive drugs, occurrence of HES-related adverse events, and intraoperative fluid intake and output were recorded. Results:A total of 251 cases were actually enrolled in this study, with 125 cases in group A-HES, and 126 cases in group NS-HES.Compared with group NS-HES, no significant change was found in the maximum changing rate of MAP and HR and the maximum change in CVP ( P>0.05) in group A-HES, and non-inferiority analysis showed that group A-HES was not inferior to group NS-HES.Compared with group NS-HES, the concentrations of BE and HCO 3-, K + , Ca 2+ and Mg 2+ were significantly increased, the concentrations of Na + and Cl - were decreased, the PT was shortened, the incidence of abnormal PT was decreased at 15 min after the end of infusion ( P< 0.05), and no significant change was found in the other parameters mentioned above in group A-HES ( P>0.05). Conclusion:The volume expanding effect of A-HES and its effect on liver and kidney function are not significantly different from those of NS-HES, however, A-HES has certain advantages in maintaining acid-base balance, electrolyte stability and coagulation function.

Objective:To explore the therapeutic efficacy and safety of elective nodal irradiation (ENI) and involved field irradiation (IFI) in intensity-modulated radiotherapy for esophageal cancer, screen the patients suitable to undergo ENI radiotherapy and provide evidences for individual treatment of esophageal cancer.Methods:A retrospective analysis was performed on the clinical data of 924 patients with esophageal cancer who received definitive intensity-modulated radiotherapy in our hospital from January 2006 to December 2015. Among them, 272 patients received ENI and the other 652 patients received IFI. The clinicopathologic characteristics of 272 cases in ENI group and 652 cases in IFI group, who were recruited according to the balance of propensity score matching method, were compared. The Kaplan-Meier method was used to calculate 1-year, 3-years and 5-years local-regional failure-free survival (LRFFS), progression-free survival (PFS) and overall survival (OS) rates. The univariate and multivariate analysis of prognostic factors were also determined by Cox proportional hazard model and Long-rank test.Results:The clinicopathologic characteristics of these two group were not significantly different ( P>0.05). The median follow-up time was 85.9 months and the follow-up rate was 95.9%. The 1-year, 3-years, 5-years PFS rates of the ENI groups were 65.3%, 31.7%, 18.4%, respectively, higher than 54.0%, 20.9%, 12.7% of the IFI group ( P=0.001). The 1-year, 3-years, 5-years OS rates of the ENI groups were 79.0%, 43.7%, 24.9%, respectively, higher than 75.0%, 31.8%, 17.2% of the IFI group ( P=0.003). In multivariate analysis, the sex, tumor volume, N stage and radiation field were independent factors for PFS and OS ( P<0.05). Subgroup analysis showed that patients with male, age≤66 year, cervical and upper-thoracic location, tumor length≤6 cm, T1-2 stage, N0-1 stage, Ⅰ-Ⅱ stage, tumor volume≤50 cm 3, dosage>60 Gy and≤2 cycles of chemotherapy in the ENI group had a better survival rate than those in the IFI group ( P<0.05). The total failure rate, local-regional failure rate in ENI group were significantly lower than those of IFI group ( P=0.001, P=0.004). The incidence of bone marrow depression≥ grade 2 and 3 in ENI group was higher than that of the IFI group ( P<0.05). However, the incidences of radioactive esophagitis≥ grade 3, radioactive pneumonia and late adverse reactions were not significantly different between these two groups ( P>0.05). Conclusion:Compared with IFI, ENI can significantly improve the long-term survival for young, early TN stage and cervical/upper-thoracic esophageal cancer patients underwent chemotherapy.
