Effect of Enhanced Recovery after Surgery with Integrated Traditional Chinese and Western Medicine on Postoperative Stress Response of Patients with Gastrointestinal Tumors.

Objective: To investigate the effect of enhanced recovery after surgery (ERAS) with integrated traditional Chinese and Western medicine on postoperative stress response of patients suffering from gastrointestinal tumors. Methods: A total of 74 patients with gastrointestinal tumors who underwent surgical treatment in our hospital from April 2019 to March 2021 were recruited and randomized into the control group and the observation group (1 : 1). The control group received routine treatment and care, while the observation group received ERAS plus integrated traditional Chinese and Western medicine. Clinical observation was performed regarding changes in preoperative mood and postoperative pain level in each group. Changes in expression levels of plasma cortisol, C-reactive protein (CRP), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-ß (TNF-ß) before and after surgery were detected in each group. Time of patients' first fart and defecation and complications after surgery in each group were recorded. Results: The visual analogue scale (VAS) of patients in the observation group after 12 and 24 h of surgery was significantly lower than that in the control group (12 h: observation group 2.0 (1.00, 3.00) vs. control group 4.00 (3.00, 5.00), p = 0.001; 24 h: observation group 2.00 (1.00, 3.00) vs. control group 3.00 (2.00, 5.00), p = 0.005). The preoperative anxiety degree of patients in the two groups was not statistically significant (p = 0.489). The plasma cortisol level of patients in the observation group after 24 and 48 h of surgery was significantly lower than that in the control group (24 h: observation group 426.54 ± 52.15 nmol/L vs. control group 508.32 ± 41.08 nmol/L, p = 0.001; 48 h: observation group 287.19 ± 44.24 nmol/L vs. control group 362.57 ± 43.46 nmol/L, p = 0.001). Patients' postoperative CRP, IL-6, IL-8, and TNF-ß expression levels in the observation group were remarkably lower than those in the control group at all time points. The first postoperative defecation came earlier in the observation group than that in the control group (observation group 76.00 h (64.50, 87.50) vs. control group 89.00 h (73.50, 116.00), p = 0.007). There was 1 postoperative urinary tract infection in the observation group and 1 postoperative intestinal obstruction and 1 incisional wound infection in the control group. Conclusion: ERAS with integrated traditional Chinese and Western medicine could effectively reduce the postoperative stress response and inflammatory reaction in patients with gastrointestinal tumors, contributing to the safe and quick recovery of gastrointestinal functions of patients.

Asymmetrical cross-modal influence on neural encoding of auditory and visual features in natural scenes.

Natural scenes contain multi-modal information, which is integrated to form a coherent perception. Previous studies have demonstrated that cross-modal information can modulate neural encoding of low-level sensory features. These studies, however, mostly focus on the processing of single sensory events or rhythmic sensory sequences. Here, we investigate how the neural encoding of basic auditory and visual features is modulated by cross-modal information when the participants watch movie clips primarily composed of non-rhythmic events. We presented audiovisual congruent and audiovisual incongruent movie clips, and since attention can modulate cross-modal interactions, we separately analyzed high- and low-arousal movie clips. We recorded neural responses using electroencephalography (EEG), and employed the temporal response function (TRF) to quantify the neural encoding of auditory and visual features. The neural encoding of sound envelope is enhanced in the audiovisual congruent condition than the incongruent condition, but this effect is only significant for high-arousal movie clips. In contrast, audiovisual congruency does not significantly modulate the neural encoding of visual features, e.g., luminance or visual motion. In summary, our findings demonstrate asymmetrical cross-modal interactions during the processing of natural scenes that lack rhythmicity: Congruent visual information enhances low-level auditory processing, while congruent auditory information does not significantly modulate low-level visual processing.

Combination of baicalein and 10-hydroxy camptothecin exerts remarkable synergetic anti-cancer effects.

BACKGROUND: 10-Hydroxy camptothecin (HCPT), a naturally occurring alkaloid, is a clinical drug for cancer chemotherapy. Baicalein (BA) is a flavonoid extracted from the root of Scutellaria baicalensis. The synergistic anti-cancer effect of BA and HCPT has not been reported. PURPOSE: To explore whether and how BA enhances the anti-cancer effect of HCPT in BGC823 cells. METHODS: Cell viability was measured by MTT assay. Apoptosis and cell cycle were analyzed through flow cytometry and western blotting analysis. DNA damage was determined by a comet assay. The activity of topoisomerase I (Topo I) was detected by the plasmid DNA relaxation assay. The synergistic anti-cancer effect of BA and HCPT in vivo was tested by BGC823 xenografted tumor model. RESULTS: BA at non-toxic doses prominently enhanced the anti-cancer activities of HCPT in BGC823, MCF7 and SMMC7721 cells. Combination treatment of BA and HCPT induced BGC823 cells apoptosis mainly via intrinsic rather than extrinsic pathways, and preferentially arresting cell cycle in G1 and G2 phases with the aid of p21. Of note, p53, the upstream regulator of cell apoptosis and cycle, was increased by 5 folds in combination group. It helped to further trigger DNA damage and inhibit Topo I catalytic activity after combination treatment of BA and HCPT. Moreover, the BGC823 xenografted tumor growth rate in nude mice was repressed in a greater degree (P< 0.01) in the combinational group than the single-drug group. CONCLUSION: HCPT and BA, a new and effective combination therapy, synergistically target Topo I and up-regulate p53 to induce cell apoptosis and cell cycle arrest.
