ObjectiveTo investigate the effect of omega-3 polyunsaturated fatty acids on delirium in elderly patients after taking gastric cancer surgery.MethodsA prospective study was conducted. Elderly patients with gastric cancer undergoing radical gastrectomy in West China Hospital of Sichuan University from June 2015 to June 2018 were divided into experimental group and control group for the purpose of research. All patients were operated by the same group of surgeons and anesthesiologists. Patients in the experimental group received intravenous infusion of 10% fish fat emulsion (Ewing) 100 mL daily from the first day after operation extra to routine treatment; patients in the control group received routine treatment after operation. The postoperative delirium, inflammation, complications, hospital stay, andre-admission on 30 days were compared between the two groups.ResultsA total of 205 patients were under research. The results were as follows. ① There were 47 delirium patients in the control group and 22 delirium patients in the experimental group. The difference between the two groups was statistically significant (P<0.001). There were 32 cases and 19 cases discovered with delirium in the control group and the experimental group during 1-3 days after operation; there were 19 cases and 6 cases were detected with delirium in the control group and the experimental group during 4-7 days after operation, respectively. The difference was considered statistically significant (P<0.05). ② Inflammation indexes of the experimental group were significantly lower than those of the control group on the 3rd and 7th day after operation, including count of WBC, C-reactive protein, interleukin-6, tumor necrosis factor-α, and platelet crit, and the difference were statistically significant (P<0.05). ③ Postoperative fever occurred in 46 patients in the experimental group, while 71 patients in the control group. The difference was statistically significant (P<0.01). ④ There were 2 cases of incision liquefaction in the control group and 1 case of mild chylous leakage in the experimental group. There was no significant difference in incision liquefaction rate and chylous leakage rate between the two groups (P>0.05). ⑤ The average hospitalization time of the experimental group was shorter than that of the control group ［(8±1) d vs. (9±2) d］. The difference was considered statistically significant (P<0.01).Conclusionω-3 polyunsaturated fatty acids can reduce postoperative delirium and improve short-term prognosis in elderly patients with gastric cancer by controlling inflammation and stress response.

Objective To analyze clinical value of early enteral nutrition following radical resection of gastric cancer. Methods Seventy-six patients with gastric cancer underwent radical resection from May 1, 2016 to July 1, 2016 in the West China Hospital of Sichuan University were included according to the inclusion criteria and exclusion criteria, then were randomly divided into observation group (36 cases) and control group (40 cases). The patients in the observation group received the enteral nutrition on day 2 following the surgery, in the control group received the conventional management. The gastrointestinal recovery and the adverse reaction were compared in these two groups. The preoperative and postoperative laboratory indicators and the body weight of the patients in both groups were analyzed. Results ① The general data such as age, gender, and body weight had no significant differences in these two groups (P>0.05). ② The first anus exhaust time and the first defecation time of the observation group were significantly shorter than those of the control group (P<0.05). ③ The adverse reaction rate of the observation group was significantly lower than that of the control group (P<0.05). ④ On admission, the serum albumin, urea nitrogen, creatinine, and lymphocyte count had no significant differences in these two groups (P>0.05). On day 5 after the operation, the serum albumin of the observation group was significantly higher than that of the control group (P<0.05). ⑤ The body weight had no significant difference in these two groups before the operation (P>0.05), which in the observation group was significantly heavier than that of the control group on day 30 after the operation (P<0.05). Conclusion Preliminary results of limited cases in this study show that early enteral nutrition following radical resection of gastric cancer is safe and effective, it could promote gastrointestinal function resumption and effectively improve nutritional status.
ObjectiveTo evaluate the infiuence of doctor-nurse double check table applied before operation on the completion of preoperative preparation in gastrointestinal surgery department of class-three grade-one hospitals. MethodsA total of 647 selective operation patients from April to September 2013 in the Department of Gastrointestinal Surgery were divided into observation group (n=315) and control group (n=332) based on admission time. After training for medical staff, the check tables were filled, and relatively high frequency issues were followed up for quality tracking. The completion of preoperative preparation was compared between the two groups after operation. ResultsCompared with the control group, the completion of preoperative preparation and satisfaction of patients of the observation group were significantly higher and the operation delay was significantly lower (P<0.05). ConclusionPreoperative application of doctor-nurse double check table can significantly improve the completion rate of preoperative preparation, the operation delay phenomenon and satisfaction of patients, promote the communication between doctors and nurses, reduce the risk of operation, and ensure the safety of surgical patients.
Objective To isolate and culture the chondroid cells and notochord cells from New Zealand rabbit immature nucleus pulposus (NP) in monolayer, and to valuate the responsiveness of rabbit disc-derived chondroid cells to notochord cells with respect to cell prol iferation and phenotype. Methods The NP cells were released from the minced immature NP of 6 New Zealand rabbits (4-week-old) by 0.2% collagenase II digestion. The chondroid cells and notochord cells were purified by discontinuous gradient density centrifugation. The chondroid cells were cultured alone (group A) andco-cultured with notochord cells (group B) (1 ∶ 1), and cell prol iferation and phenotype including proteoglycan and collagen II were evaluated. The cells in both groups were observed by the inverted microscope, and the survival rates of the primary and passage cells were detected by toluidine blue staining. The growth curves of the second passage cells in both groups were determined by MTT. Besides, the expressions of proteoglycan and collagen II of the primary and passage cells were examined by toluidine blue and immunocytochemistry staining. Results The notochord cells and chondroid cells were isolated and purified. With the diameter of 10-15 μm, the notochord cell had abundant intracytoplasmic vesicles, while the chondroid cell, with the diameter of 4-6 μm, had no intracytoplasmic vesicle. The cell survival rate was 89.0%-95.3% in group A and 91.3%-96.3% in group B. There was no significant difference between the same passages in both groups (P gt; 0.05). The co-cultured cells (group B) increased in cell prol iferation compared with the chondroid cells alone (group A) in repeated experiments. The cells in group A reached their logarithmic growth phase after 3-4 days of culture, while the cells in group B did after 2 days of culture. The cell prol iferation in group B was more than that in group A after 4-day culture (P lt; 0.05). The cocultured cells retained their phenotype for 5 passages, while parallel-cultured chondroid cells lost the expression of proteoglycan and collagen II after the third passage. Conclusion The notochord cells are conducive for the prol iferation and phenotypekeeping of the chondroid cells and may play a key role in preventing degeneration of the disc.
