Objective: To analyze the application of accelerated rehabilitation surgery in elderly patients with gastric cancer surgery and its influence on inflammation and nutritional indicators. Methods: From October 2017 to October 2018, 80 elderly patients with gastric cancer who underwent gastrectomy in Shaoxing People's Hospital were selected.According to random number table method, they were randomly divided into traditional control group and ERAS group, with 40 cases in each group.The traditional control group was treated by traditional perioperative treatment + operation, while ERAS group was treated with ERAS perioperative treatment + operation.The recovery and complications, inflammation and nutritional changes before operation, 1 day after operation and 3 days after operation, and the improvement of quality of life after operation were compared and analyzed between the two groups. Results: In the ERAS group, the first exhaust time[(2.3±0.8)d] and defecation time[(2.5±0.4)d]were shorter than those in the traditional control group[(3.5±0.5)d and (3.7±0.6)d], and the incidence rate of complications (7.5%) was lower than that in the traditional control group (35.0%), the differences were statistically significant (t=8.72, 10.52, χ²=9.04, all P<0.05). On the first day after operation, the serum levels of tumor necrosis factor-alpha (TNF-α) and interleukin-6(IL-6) in the ERAS group were (28.3±4.9)μg/L and (23.1±5.8)μg/L, respectively, which were lower than those in the traditional control group[(39.8±6.7)μg/L and (34.5±8.1)μg/L](t=8.76, 7.24, all P<0.05). The serum TNF-α and IL-6 levels in the ERAS group on the 3rd day after operation were (18.4±6.2)μg/L and (18.3±3.2)μg/L, respectively, which were lower than those in the traditional control group[(26.2±5.1)μg/L and (26.5±4.8)μg/L](t=6.14, 8.99, all P<0.05). The serum levels of albumin (Alb) and prealbumin (PRE) in the ERAS group on the first day after operation were (31.1±0.7)g/L and (161.3±7.2) mg/L, respectively, which were lower than those in the traditional control group[(30.2±0.9)g/L and (154.3±4.8)mg/L](t=4.99, 5.12, all P<0.05). The serum levels of Alb and PRE in the ERAS group on the 3rd day after operation were (33.4±0.5)g/L and (172.1±5.0)mg/L, respectively, which were lower than those in the traditional control group[(31.9±0.8)g/L and (165.3±3.2)mg/L](t=10.06, 7.24, all P<0.05). The WHOQOL-BREF score of the ERAS group[(91.4±6.5)points]was higher than that of the traditional control group[(80.3±7.8)points](P<0.05). Conclusion Accelerated rehabilitation surgery has good effect for elderly gastric cancer surgery.It can maintain the inflammation and nutritional status of patients after operation.It is worthy of clinical reference.

Objective:To investigate the clinical value of three-dimensional arterial spin marker imaging(3D-ASL) for evaluating collateral circulation compensatory status in patients with cerebral infarction.Methods:A total of 24 patients with cerebral infarction who were treated at Wenzhou Hospital of Traditional Chinese Medicine Affiliated to Zhejiang University of Chinese Medicine from September 2017 to January 2019 were examined by 1.5-T high-field MR scanner.The changes of cerebral blood flow(CBF) between the infarcted area and the contralateral normal area were compared when the labeled delay time(PLD)=1.5s and PLD=2.5s, and the patients were divided into the group with strong collateral circulation compensation and the group with weak collateral circulation compensation according to the difference in lesion area measured by 3D-ASL(PLD=1.5s and 2.5s). The changes of national institutes of health stroke scale(NIHSS) score and Bathel index at admission and 15 days after admission were compared.Results:3D-ASL measurement of PLD=1.5s showed that the CBF value in the infarcted area was (33.70±20.83)mL/(100g×min), which was significantly lower than that in the contralateral normal area(PLD=1.5s)[(49.93±13.13)mL/(100g×min)]( t=3.229, P<0.05). When PLD=2.5s, ASL measurement results showed that the CBF value in the infarcted area increased significantly[(58.26±23.50)mL/(100g×min) vs.(33.70±20.83)mL/(100g×min)]( t=3.831, P<0.05), and the CBF value in the contralateral normal area also increased significantly[(68.29±14.03)mL/(100g×min) vs.(49.93±13.13)mL/(100g×min)]( t=4.681, P<0.05). At this time, the CBF value in the infarcted area was still significantly lower than that in the contralateral normal area[(58.26±23.50)mL/(100g×min) vs.(68.29±14.03)mL/(100g×min)]( t=1.795, P<0.05). On the day of admission, the BI index of patients in the weak collateral circulation compensation group(12 cases) was significantly higher than that in the strong collateral circulation compensation group(12 cases)[(90.42±10.50) vs.(67.92±27.57)]( t=2.642, P<0.05), and the NIHSS score was significantly lower than that in the strong collateral circulation compensation group[(1.25±1.01) vs.(3.83±3.62)]( t=2.378, P<0.05). After 15 d of admission, there were no significant differences in BI index and NIHSS score between the two groups(all P>0.05). Conclusion:3D-ASL with different delay time can effectively and intuitively reflect collateral circulation compensation of patients with cerebral infarction, and it has very important reference value for the evaluation of patients' disease and the formulation of clinical treatment plan.
