Background: Optimal adjuvant chemotherapy after laparoscopic surgery in gastric cancer (GC) patients is still undefined. We aimed to evaluate the efficacy of S‐1 plus oxaliplatin (SOX) and capecitabine plus oxaliplatin (CAPOX) in patients with GC after laparoscopic gastrectomy. Methods: A non‐inferiority randomized controlled clinical trial was performed in China. Patients with advanced GC who underwent laparoscopic D2 gastrectomy were randomly assigned to receive SOX and CAPOX regimens. Results: In total, 191 patients were screened between May 2018 and June 2019, and 140 (73.3%) were included in the modified intent‐to‐treat analysis (mITT), of whom 69 and 71 were assigned to the SOX and CAPOX groups, respectively. The SOX group had similar 3‐year overall survival (OS) and disease‐free survival to the CAPOX group. Subgroup analysis revealed significantly better OS in the SOX group for male patients ([HR] = 0.395; 95% [CI], 0.153–1.019; p = 0.045), age >60 (HR = 0.219; 95% [CI], 0.064–0.753; p = 0.016), tumors in the gastric antrum (HR = 0.273; 95% [CI], 0.076–0.981; p = 0.047), and moderately differentiated tumors (HR = 0.338; 95% [CI], 0.110–1.041; p = 0.041). There were no significant differences observed in terms of adverse events and recurrence patterns between the two groups. Conclusion: Adjuvant SOX was non‐inferior to CAPOX treatments for patients with GC who underwent curative laparoscopic D2 gastrectomy. For male patients, aged >60 years, tumors in the gastric antrum, and moderately differentiated tumors, adjuvant SOX may achieve an improvement compared with CAPOX. [ABSTRACT FROM AUTHOR]

Objective To study the intervention effect of Jianpi Zhidong Decoction on the expressions of Cx43 and Cx30 in the cortex, corpus striatum, hypothalamus, and hippocampus of tic disorder mice. Methods According to the random number table method, 60 male ICR mice were divided into the blank control group(n=15) and modeling group(n=45). The mice in the modeling group were intraperitoneally injected with iminodipropanitrile(350 mg/kg, once a day for 7 days) to establish a tic disorder model, and the mice in the blank control group were intraperitoneally injected with equal volume of normal saline. The stereotyped behavior score was calculated to evaluate the success of modeling. According to the random number table method, the mice in the modeling group were divided into the model group, tiapride group(29.5 mg/kg) and Jianpi Zhidong Decoction group(17.8 g/kg), with 15 mice in each group. The drug was administered by gavage for 4 weeks. After administration, stereotyped behavior score was calculated. The positive protein expression, protein expression, and mRNA expression of Cx43 and Cx30 in the cortex, corpus striatum, hypothalamus and hippocampus were determined by immunohistochemistry, Western blotting and real-time PCR. Results Compared with the blank control group, the stereotyped behavior score of mice in the model group was increased(P<0.05). Compared with the model group, the stereotyped behavior scores of mice in the tiapride group and the Jianpi Zhidong Decoction group were decreased(P<0.05). Compared with the blank control group, the average optical densities of Cx43 in the cortex, corpus striatum, hypothalamus, and hippocampus of mice in model group were decreased(P<0.05). Compared with the model group, the average optical densities of Cx43 in the cortex and hippocampus in the tiapride group were increased, and the average optical densities of Cx43 in the cortex, corpus striatum, and hippocampus in the Jianpi Zhidong Decoction group were increased(P<0.05). Compared with the tiapride group, the average optical density of Cx43 in the cortex in the Jianpi Zhidong Decoction group was increased(P<0.05). Compared with the blank control group, the average optical densities of Cx30 in the cortex, corpus striatum, hypothalamus, and hippocampus of mice in model group were decreased(P<0.05). Compared with the model group, the average optical densities of Cx30 in the corpus striatum and hypothalamus in the tiapride group were increased, and the average optical densities of Cx30 in the cortex, corpus striatum, and hippocampus in the Jianpi Zhidong Decoction group were increased(P<0.05). Compared with the tiapride group, the average optical density of Cx30 in the hippocampus in the Jianpi Zhidong Decoction group was increased(P<0.05). Compared with the blank control group, the protein expressions of Cx43 in the cortex, corpus striatum, and hippocampus of mice in the model group were decreased(P<0.05). Compared with the model group, the protein expression of Cx43 in the cortex in the tiapride group was increased, and the protein expressions of Cx43 in the cortex, corpus striatum, and hippocampus in the Jianpi Zhidong Decoction group were increased(P<0.05). Compared with the blank control group, the protein expressions of Cx30 in the cortex and hippocampus of mice in the model group were decreased(P<0.05). Compared with the model group, the protein expressions of Cx30 in the cortex and hippocampus in the tiapride group and the Jianpi Zhidong Decoction group were increased(P<0.05). Compared with the blank control group, the mRNA expressions of Cx43 in the cortex, corpus striatum and hippocampus in the model group were decreased(P<0.05). Compared with the model group, the mRNA expressions of Cx43 in the cortex, corpus striatum, and hippocampus in the tiapride group and the Jianpi Zhidong Decoction group were increased(P<0.05). Compared with the blank control group, the mRNA expressions of Cx30 in the cortex and hippocampus in the model group were decreased(P<0.01). Compared with the model group, the mRNA expressions of Cx30 in the cortex and hippocampus in the tiapride group and the Jianpi Zhidong Decoction group were increased(P<0.05). Conclusion The decreased expression of Cx43 and Cx30 in the cortex, corpus striatum, hypothalamus, and hippocampus may be involved in the occurrence of stereotyped behavior in tic disorder mice. The intervention mechanism of Jianpi Zhidong Decoction may be related to the increased expression of Cx43 and Cx30 in various brain regions. [ABSTRACT FROM AUTHOR]
