Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

AIM:To investigate the impact of es-ketamine-mediated opioid-free anesthesia(OFA)on postoperative gastrointestinal function in patients undergoing laparoscopic distal gastrectomy for gas-tric cancer.METHODS:A total of 150 pa-tients,scheduled for elective laparoscopic distal gas-trectomy for gastric cancer and meeting the inclu-sion and exclusion criteria,were randomly assigned to either the OFA group or the opioid-based anes-thesia(OBA)group using a random number ta-ble,with 75 patients in each group.The OFA group was administered an anesthesia regimen pri-marily consisting of esketamine,while the OBA group received conventional opioid anesthesia,pri-marily consisting of sufentanil and remifentanil.The primary outcome measure was postoperative flatus time,defined as the interval from the end of sur-gery to the first passage of gas.RESULTS:The OFA group exhibited a shorter postoperative flatus time compared to the OBA group(P＜0.01).Intraopera-tive blood loss and norepinephrine consumption were significantly less in the OFA group compared to the OBA group(P＜0.05);the postoperative HADS-D score was better in the OFA group than in the OBA group,and both the OFA and OBA groups showed significantly lower postoperative HADS-A and HADS-D scores compared to their preoperative levels(P＜0.05);the incidence rate of abdominal distension was significantly lower in the OFA group compared to the OBA group(P＜0.05).CONCLUSION:The use of esketamine-mediated opioid-free anesthesia can expedite gastrointestinal function recovery,reduce hospital stay duration,and decrease postoperative adverse reactions in patients undergoing laparo-scopic distal gastrectomy for gastric cancer.

Objective:To explore the differences in resting-state brain functional activity in obsessive-compulsive disorder (OCD) patients with and without sensory phenomena (SP).Methods:Clinical data from 102 OCD patients (60 males, 42 females; age 18-50(27±8) years) who visited the OCD outpatient clinic at the Affiliated Brain Hospital of Nanjing Medical University between August 2021 and December 2022 were prospectively collected. Based on the presence of sensory phenomena, patients were categorized into 70 cases with sensory phenomena (Sensory Phenomena Group) and 32 cases without sensory phenomena (Non-Sensory Phenomena Group). Additionally, 50 age-matched healthy controls (Control Group, 24 males, 26 females; age 18-49(25±6) years) were recruited. Resting-state functional magnetic resonance imaging (rs-fMRI) was analyzed using the amplitude of low-frequency fluctuations (ALFF) and functional connectivity (FC) between differential brain regions. One-way ANOVA and post-hoc tests were used to compare group differences. Spearman correlation and binary logistic stepwise regression were applied to analyze the associations between SP and brain functional activity.Results:Compared to healthy controls, OCD patients showed decreased ALFF in bilateral middle frontal gyri, left superior frontal gyrus, right angular gyrus, and right supramarginal gyrus ( F=17.29-32.99, all P<0.05). The SP group exhibited increased ALFF in the right triangular part of the inferior frontal gyrus ( F=23.47, P<0.05) and decreased ALFF in the left superior parietal gyrus and left postcentral gyrus ( F=18.80, 15.04; both P<0.05). The non-SP group demonstrated increased ALFF in the left supramarginal gyrus and left postcentral gyrus ( F=19.64, 15.04; both P<0.05) and decreased ALFF in the left superior frontal gyrus, right middle frontal gyrus, and left angular gyrus ( F=17.29-35.52, all P<0.05). Reduced FC was observed between the left middle frontal gyrus and left angular gyrus, left middle frontal gyrus and right angular gyrus and left and right angular gyri ( F=17.29-23.47, all P<0.05). The SP group showed lower FC between the left middle frontal and left angular gyrus than the non-SP group ( F=23.47, P<0.05). Positive correlations with SP were found for ALFF in the right triangular part of the inferior frontal gyrus, left superior frontal gyrus, and right middle frontal gyrus (r=0.40, 0.35, 0.31; all P<0.05). Negative correlations were observed for ALFF in the left supramarginal gyrus, left superior parietal gyrus, and left postcentral gyrus (r=-0.38, -0.47, -0.52; all P<0.05) and FC between the left middle frontal gyrus-left angular gyrus and left middle frontal gyrus-right angular gyrus (r=-0.24, -0.21; both P<0.05). OCD patients with increased ALFF in the left superior frontal gyrus and right middle frontal gyrus, along with decreased ALFF in the left supramarginal gyrus, left superior parietal gyrus, left postcentral gyrus, and reduced FC between the left middle frontal gyrus-right angular gyrus, had a higher likelihood of SP (log OR (95% CI)=8.5(4.0-14.2), 8.0(1.7-16.4), -8.9(-15.2--4.4), -5.2 (-9.1--2.3), -4.1(-6.9--1.7), -7.0(-13.2--1.8); all P<0.05). Conclusion:Altered functional activity in the left superior frontal gyrus, right middle frontal gyrus, left supramarginal gyrus, left superior parietal gyrus, left postcentral gyrus, and abnormal FC between the left middle frontal gyrus and right angular gyrus represent key neuroimaging features of OCD patients with SP.
