Objective To investigate the effects and mechanism of Yuyin Qianyang Tongluo Formula on cognitive function in Alzheimer's disease mice.Methods Transgenic negative mice were designated as the normal group,while APP/PS1 double transgenic mice were randomly divided into six groups(ni=6 per group):model group,low-dose Yuyin Qianyang Tongluo Formula group,medium-dose group,high-dose group,and positive drug group.The Yuyin Qianyang Tongluo Formula low-,medium-,high-dose groups correspondingly received intragastric administration of 0.75,1.5,and 3 g·kg-1·d-1,respectively.The positive drug group received 2 mg·kg-1·d-1 donepezil hydrochloride tablets,while the model and normal groups received equal volumes of saline.All groups were treated once daily for 8 weeks.Behavioral tests were conducted using the Morris water maze and Y-maze.Hippocampal β-amyloid(Aβ)1-42 level was measured by enzyme-linked immunosorbent assay(ELISA).Hippocampal CA1 and CA3 neurons were observed hematoxylin-eosin(HE)staining,and Nissl bodies were examined Nissl staining.Protein expression levels of Aβ transporter low-density lipoprotein receptor-related protein 1(LRP-1)and endoplasmic reticulum stress marker glucose-regulated protein 78(GRP78)were detected by Western Blot analysis.Results(1)Compared with the normal group,the model group showed significantly prolonged escape latency(P＜0.000 1),reduced platform crossings,decreased movement distance and time around the platform of Morris water maze test(P＜0.05 or P＜0.01),significantly lower spontaneous alternation percentage in Y-maze test(P＜0.05),and significantly elevated hippocampal Aβ1-42 level(P＜0.000 1).Compared with the model group,all Yuyin Qianyang Tongluo Formula dose groups and the positive drug group exhibited significantly shortened escape latency of Morris water maze test(P＜0.000 1).The high-dose Yuyin Qianyang Tongluo Formula group and positive drug group showed significantly increased platform crossings,movement distance and time around the platform of Morris water maze test(P＜0.05),significantly higher spontaneous alternation percentage in Y-maze test(P＜0.05).All Yuyin Qianyang Tongluo Formula dose groups and the positive drug group showed significantly reduced hippocampal Aβ1-42 level(P＜0.000 1).(2)Compared with the normal group,the model group exhibited disordered and deformed hippocampal neurons and Nissl bodies.Compared with the model group,all Yuyin Qianyang Tongluo Formula groups and positive drug group showed improved neuronal and Nissl body organization,with the improvement degree positively correlated with dosage.(3)Compared with the normal group,the model group showed decreased LRP1 level and increased GRP78 level,but there were no statistically significant differences(P＞0.05).Compared with the model group,the high-dose Yuyin Qianyang Tongluo Formula group and positive drug group showed increased LRP1 level,while all Yuyin Qianyang Tongluo Formula dose groups and positive drug group exhibited decreased GRP78 level,but there were no statistically significant differences(P＞0.05).Conclusion Yuyin Qianyang Tongluo Formula significantly improves cognitive and memory function in model mice in a dose-dependent manner,potentially through reducing Aβ aggregation in the brain via endoplasmic reticulum stress pathway.

Objective:To investigate the treatment and prognosis of esophageal cancer patients with pulmonary resection history.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 58 esophageal cancer patients with pulmonary resection history who were admitted to Chest Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Jiangxi Provincial People's Hospital from May 2019 to April 2024 were collected. There were 52 males and 6 females, aged (69±3)years. Observation indicators: (1) surgical and postopera-tive conditions; (2) postoperative pathological examination results; (3) follow-up; (4) stratified analysis. Comparison of measurement data with normal distribution between groups was conducted using the independent sample t test. Comparison of count data between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data between groups was conducted using the non-parametric rank sum test. The Kaplan-Meier method was used to plot survival curve and calculate survival rate, and the Log-rank test was used for survival analysis. Results:(1) Surgical and postoperative conditions. Of the 58 esophageal cancer patients, 49 patients underwent transthoracic approach (26 cases of ipsilateral approach and 23 cases of contralateral approach of pulmonary resection history), and 9 patients underwent mediastinoscopic-laparoscopic approach. There were 57 cases with R 0 resection and 1 case with R 2 resection because of tumor invading carina. The total operation time of 58 patients was (246±27)minutes, and the volume of intraoperative blood loss was (114±29)mL. There was no unplanned reoperation or perioperative death for all patients. The duration of postoperative hospital stay of 58 patients was (10.4±4.6)days, and time for intensive care unit stay was (1.4±0.5)days, and no patient readmitted to intensive care unit due to changes in conditions. The postoperative total incidence of complications of 58 patients was 41.4%(24/58). The Clavien-Dindo grading of complications for all patients was 1-2 grade. (2) Postoperative pathological examination results. Results of postoperative pathological examination showed there were 51 cases of squamous cell carcinoma, 6 cases of adenocarcinoma, and 1 case of melanoma. Number of lymph node dissected of 58 patients was 27±6. The ratio of patient with positive lymph node was 37.9%(22/58). One patient may experience more than 1 region of positive lymph node metastasis. Results of postoperative pathological staging showed 5 cases of ⅠA stage, 2 cases of ⅠB stage, 13 cases of ⅡA stage, 15 cases of ⅡB stage, 4 cases of ⅢA stage, 16 cases of ⅢB stage, and 3 cases of ⅣA stage. Thirteen of the 58 patients underwent neoadjuvant therapy, with the pathological staging as 6 cases of Ⅰ stage, 4 cases of Ⅱ stage, 3 cases of ⅢB stage after therapy. Results of postoperative tumor regression grade for the 13 patients with neoadjuvant therapy showed 4 cases of grad 0, 3 cases of grade 1, 6 cases of grade 2. (3) Follow-up. All 58 patients were followed for 24 (4, 50)months, and no patient died within 90 days after surgery. During the follow-up period, 19 patients experienced tumor recurrence and metastasis and 17 patients died. Twenty-one patients underwent postoperative adjuvant therapy, including 7 cases with chemoradiotherapy, 7 cases with chemotherapy, 3 cases with chemotherapy and immunotherapy, 2 cases with immuno-therapy, 2 cases with radiotherapy. The postoperative 1-, 2-year overall survival rates of the 58 patients were 91.3%, 78.7%, respectively, of whom undergoing McKeown surgery and mediastinoscopic-laparoscopic surgery with postoperative 1-, 2-year overall survival rates as 89.2%, 83.1% and 85.7%, 53.6%, respectively. The postoperative 1-, 2-year esophageal cancer specific survival rates for patients undergoing McKeown surgery and mediastinoscopic-laparoscopic surgery were 94.4%, 87.9% and 85.7%, 71.4%, respectively. There was no significant difference in postoperative 1-, 2-year overall survival rates and postoperative 1-, 2-year esophageal cancer specific survival rates between patients undergoing McKeown surgery and mediastinoscopic-laparoscopic surgery ( P>0.05). (4) Stratified analysis. Of the 49 patients underwent transthoracic approach for esophageal cancer, there were significant differences in surgical method, surgical type, time of chest surgery, cases with upper mediastinal lymph node dissection, and duration of postoperative hospital stay between patients with pulmonary resection history as ipsilateral approach and contralateral approach ( χ2=11.74, 11.68, t=-2.25, χ2=8.45, t=-2.17, P<0.05), and there was no significant difference in total operation time, volume of intraoperative blood loss, the number of lymph node dissected, post-operative total complications, and postoperative pathological TNM staging ( P>0.05). For patients with pulmonary resection history as ipsilateral approach and contralateral approach, the postopera-tive 1-, 2-year esophageal cancer specific survival rates were 95.5%, 95.5% and 81.4%, 71.1%, showing a significant difference between them ( χ2=5.63, P<0.05). Conclusions:The transthoracic approach and mediastinoscopic-laparoscopic approach are safe and feasible for esophageal cancer patients with pulmonary resection history. Compared with patients with pulmonary resection history as contralateral approach, patients with pulmonary resection history as ipsilateral approach have a higher ratio of McKeown surgery, minimally invasive surgery and upper mediastinal lymph node dissection, shorter time of chest surgery and duration of postoperative hospital stay, better esophageal cancer specific survival rate. And there is no increase in perioperative risk.
