Objective:To explore the application of anterior esophageal wall full layer fixation and gastric tube guidance in total laparoscopic overlap method for intracorporeal esophagojejunostomy.Methods:Overlap esophagojejunostomy with anterior esophageal wall full layer fixation and gastric tube guidance is suitable for patients with advanced gastric cancer (clinical stage: cT1b~4aN0~3M0) and esophageal invasion <3 cm, who underwent radical total gastrectomy+ overlap esophagojejunostomy. The main operation procedure was performed as follows: A titanium clip was used for fixation of the full anterior wall of esophagus before overlap esophagojejunostomy, and the side‐to‐side esophagojejunostomy was performed with the linear stapler under the guidance of gastric tube. Then the titanium clip was removed after confirming that the correct cavity was entered. Finally, the common outlet was closed by two barbed sutures. A descriptive case series study was conducted. The clinical data of patients who underwent laparoscopic radical gastrectomy and overlap esophagojejunostomy with anterior esophageal wall full layer fixation and gastric tube guidance in Guangdong Provincial Hospital of Chinese medicine and the First Affiliated Hospital of Guangzhou University of Chinese medicine from May 2021 to June 2023 were retrospectively analyzed.Results:A total of 42 patients were collected, and all of them were successfully completed laparoscopic total radical gastrectomy without conversion to laparotomy or perioperative death. The esophagojejunostomy time, operative time, intraoperative blood loss was 17(5‐25) minutes, (258.8±38.0) minutes and 50(20‐200) ml, respectively. The incidence of esophageal false lumen was 0%, and there were no intraoperative complications. The time of gastric tube removal, initial fluid diet intake and the duration of postoperative hospital were 2(1‐5) , 4(1‐8) and 8(4‐21) days, respectively. There were no postoperative anastomotic hemorrhage, anastomotic stenosis and other related complications. One patient (2.38%) developed a Clavien‐Dindo IIIb complication, which was abdominal hemorrhage after operation. The second surgical exploration confirmed that the patient was bleeding due to gastroduodenal artery rupture. After intraoperative suture hemostasis, fluid expansion, blood transfusion and other treatments, the patient was discharged on the 15th day after the operation. Three patients (7.14%) developed Clavien‐Dindo grade II complications, including anastomotic leakage, chylous leakage and pulmonary infection, and were discharged after conservative treatment such as anti‐infection and prolonged retention of drainage tube.Conclusions:Laparoscopic overlap method for intracorporeal esophagojejunostomy with anterior esophageal wall fixation and gastric tube guidance can shorten the time of esophagojejunostomy and prevent the occurrence of false lumen, and do not increase anastomose‐related complications.

Objective: To explore the bidirectional correlation between daily physical activity and different emotional states of university students with sports major, and to provide theoretical basis for promoting equality between physical and mental health of college students. Methods: The accelerometer and daily emotion scale were used to evaluate 219 physical education major college students recruited from Tianjin University of Sport. Correlation analysis, intra group correlation coefficient analysis and Harman single factor method were used to test the data, and Mplus 7.4 was used to analyze cross hysteria. Results: Physical activity was positively correlated with high arousal/low arousal positive emotion, and negatively correlated with low arousal/high arousal negative emotion ( r=0.94, 0.63, -0.28, -0.17, P <0.05). The cross lag model showed that physical activity on Thursday and Friday positively predicted high arousal positive emotion on Friday and Saturday, and high arousal positive emotion on Thursday and Friday positively predicted physical activity on Friday and Saturday( β =0.91, 0.20; 0.88, 0.39, P ＜0.05). Low arousal positive emotion on Thursday and Friday was a positive prediction of physical activity on Friday and Saturday, but only physical activity on Thursday positively predicted low arousal positive emotion on Friday( β=0.68, 0.35, 0.70, P ＜0.05). Low arousal negative emotion on Thursdays and Fridays negatively predicted physical activity on Friand and Saturdays( β=-0.37, -0.40, P ＜0.05). Conclusion There is a bidirectional correlation between daily physical activity and positive emotion, but a weak correlation with negative emotion. Attention should be paid to the emotional benefits of physical activity and the increasing physical activity by greater mood improvements.

Objective:To investigate the effect of prospective intervention on emergence agitation and postoperative recovery in patients with chronic sinusitis during preoperative visits.Methods:A total of 80 patients with chronic sinusitis who underwent general anesthesia in Dayi County People′s Hospital of Chengdu City from December 2019 to October 2020 were selected and randomly divided into group D and group G, with 40 patients in each group. Group D received preoperative visit with conventional methods and group G received preoperative visit with prospective intervention methods. The hemodynamic changes of patients in the two groups at 30 min before the operation (T 1) and 1 (T 2), 5 (T 3), 10 (T 4) and 30 min (T 5) after tracheal tube extraction were recorded. The anxiety and depression scores of patients before the intervention and 1 d after the operation were compared between the two groups. The incidence of emergence agitation after the operation and complications during anesthesia awakening period were observed in the two groups, sino-nasal outcome test-20 (SNOT-20) was used to assess the postoperative recovery. Results:The incidence of emergence agitation in group G was lower than that in group D: 7.5%(3/40) vs. 25.0%(10/40), the difference was statistically significant ( χ2 = 4.50, P<0.05). There was no significant difference in systolic blood pressure, diastolic blood pressure and heart rate between the two groups at T 1 and T 5 ( P>0.05), but the level of above indicators in group G at T 2, T 3 and T 4 were significantly higher than those in group D ( P<0.05). The scores of State-Trait Anxiety Inventory(S-AI) and Self-Rating Depression Scale (SDS) in group G at the first day after the operation were significantly lower than those in group D: (35.45 ± 5.32) scores vs. (39.35 ± 4.91) scores, (35.42 ± 7.82) scores vs. (38.76 ± 5.21) scores, the differences were statistically significant ( P<0.05). The incidence of complications during anesthesia awakening period in group G was slightly lower than that in group D ( P>0.05). After the operation, the scores of sinusitis symptoms and nasal symptoms in the two groups were significantly decreased compared with those before the operation, and the scores of group G were significantly lower than those in group D ( P<0.05). Conclusions:Prospective intervention before anesthesia in patients with chronic sinusitis surgery can reduce stress response, improve bad mood, reduce the incidence of emergence agitation, and promote the postoperative recovery.

Salvianolic acid A (SalA) is an effective compound extracted from traditional Chinese medicine Bunge. The Forkhead box O3a (FOXO3a) signaling pathway plays crucial roles in the modulation of ischemia-induced cell apoptosis. However, no information about the regulatory effect of SalA on FoxO3a is available. To explore the anti-cerebral ischemia effect and clarify the therapeutic mechanism of SalA, SH-SY5Y cells and Sprague-Dawley rats were applied, which were exposed to oxygen glucose deprivation/reoxygenation (OGD/R) and middle cerebral artery occlusion/reperfusion (MCAO/R) injuries, respectively. The involved pathway was identified using the specific inhibitor LY294002. Results showed that SalA concentration-dependently inhibited OGD/R injury triggered cell viability loss. SalA reduced cerebral infarction, lowered brain edema, improved neurological function, and inhibited neuron apoptosis in MCAO/R rats, which were attenuated by the treatment of phosphatidylinositol-4,5-bisphosphate 3-kinase (PI3K) specific inhibitor LY294002. SalA time- and concentration-dependently upregulated the phosphorylation levels of protein kinase B (AKT) and its downstream protein FOXO3a. Moreover, the nuclear translocation of FOXO3a was inhibited by SalA both and , which was also reversed by LY294002. The above results indicated that SalA fought against ischemia/reperfusion damage at least partially the AKT/FOXO3a/BIM pathway.

OBJECTIVE: To explore the clinical and laboratory characteristics of 5 patients with myeloid leukemia and t(12;22)(p13;q12). METHODS: Bone marrow cells were cultured for 24 h and analyzed by standard R-banding. Rearrangement of the MN1 gene was detected by fluorescence in situ hybridization (FISH) using dual color break-apart MN1 probes. MN1-ETV6 and ETV6-MN1 fusion genes were detected by reverse transcription polymerase chain reaction (RT-PCR). And the products were subjected to direct sequencing. RESULTS: Among the 5 patients, 2 had AML-M0, 2 had AML-M4, and 1 had CMML at the initial diagnosis. t(12;22)(p13;q12) was the primary abnormality among all patients. Rearrangements of MN1 gene were detected by FISH in all patients. MN1-ETV6 and ETV6-MN1 fusion genes were detected respectively in 4 and 3 patients. CONCLUSION t(12;22)(p13;q12) is a rare but recurrent chromosomal abnormality in myeloid leukemia, and is related to poor prognosis. allo-SCT is valuable for patients with t(12;22)(p13;q12).
