RESUMEN
Objective:To explore the effectiveness of short-term prehabilitation in elderly patients undergoing gastrointestinal tumor surgery.Methods:Elderly patients(139 cases) with gastrointestinal tumors who were admitted to Nanfang Hospital, Southern Medical University for surgery from December 2020 to January 2022 were included through the purposive sampling method, and were divided into the intervention group (69 cases) and the control group (70 cases) according to the patient's wishes using a quasi-experimental research design of non randomized grouped. Routine perioperative nursing was used in the control group, while the short-term prehabilitation was used in the intervention group in addition. The incidence of postoperative complications, the performance indicators, and postoperative functional recovery indicators were analyzed in the two groups.Results:The 6MWD in the intervention group of 1 day and 7 days after the surgery were (460.93 ± 76.36) m and (391.72 ± 72.93) m, which were significant higher than those in the control group, (423.69 ± 72.88) m and (351.13 ± 65.04) m ( t = 8.65, 12.01, both P<0.05). The first exhaust time, first postoperative ambulatory time, the first full fluid intake time and the duration of drainage tube indwelling in the intervention group were (51.28 ± 21.74) h, (33.93 ± 12.50) h, (69.39 ± 29.36) h and (4.30 ± 1.44) d, which were significant lower than those in the control group, (71.51 ± 23.68) h, (47.37 ± 14.58) h, (96.29 ± 38.36) h and (5.35 ± 2.09) d ( t values were -5.83 - -3.44, all P<0.05). Besides, the best critical value of preoperative 6MWD to predict postoperative rehabilitation effect was 477.5 m, with a sensitivity of 68% and specificity of 71%. Conclusions:Short-term prehabilitation improves the perioperative functional reserve and promotes overall functional recovery after surgery to a certain extent, and the postoperative functional recovery effect may be better when the patient′s preoperative 6MWD reaches 477.5 m.
RESUMEN
OBJECTIVE:To establish HPLC fingerprint of Qingbi granules.METHODS:HPLC method was adopted.The determination was performed on Diamonsil C18 column with mobile phase consisted of methanol-0.3％ phosphoric acid (gradient elution) at the flow rate of 1.0 mL/min.The detection wavelength was set at 260 nm,and column temperature was 25 ℃.The sample size was 10 μL.Using baicalin as reference,HPLC chromatograms of 10 batches of samples were determined.Common peak identification and similarity evaluation were performed by using TCM Chromatographic Fingerprint Similarity Evaluation Software (2.0 edition).RESULTS:There were 29 common peaks in HPLC chromatograms of 10 batches of samples.The similarity among the 10 batches was more than 0.90.After validation,HPLC chromatograms of 10 batches of samples were in line with control fingerprints.CONCLUSIONS:Established fingerprints can provide reference for identification and quality evaluation of Qingbi granules.
