Background: The goal of this study is to disclose the clinically significant genomic alterations in the Chinese and Western patients with intrahepatic cholangiocarcinoma., Methods: A total of 86 Chinese patients were enrolled in this study. A panel of 579 pan-cancer genes was sequenced for the qualified samples from these patients. Driver genes, actionability, and tumor mutational burden were inferred and compared to a cohort of Western patients., Results: Totally, 36 and 12 driver genes were identified in the Chinese and Western cohorts, respectively. Of them, seven driver genes (IDH1, KRAS, TP53, BAP1, PBRM1, ARID1A, and NRAS) were shared by the two cohorts. Four driver genes (SPTA1, ARID2, TP53, and GATA1) were found significantly correlated with the tumor mutational burden. For both cohorts, half of the patients had actionable mutations. The two cohorts shared the most actionable genes but differed much in their frequency. Though KRAS mutations were at the first and second actionable rank respectively for the Chinese and Western populations, they were still at a relatively low level of actionable evidence., Conclusions: The study on the clinical significance of genomic alterations directs the future development of precision medicine for intrahepatic cholangiocarcinoma treatment.

Objective: Recent studies have expressed concern about the infrequent and declining use of electroconvulsive therapy (ECT) in the United States. However, it is not known whether the US experience reflects changing global practice or one that varies between countries. This observational study examined use of ECT in the largest psychiatric hospital in China's third largest city over a 4-year period, 2014 to 2017., Methods: Unduplicated electronic medical records concerning all inpatients with psychiatric diagnoses were examined. Electroconvulsive therapy utilization rates, correlates of ECT use, and its association with readmission within the 6 months following discharge were evaluated using bivariate and multivariate logistic regression analyses., Results: Of 13,831 hospitalized patients, 2460 (17.8%) received ECT. Logistic regression analysis showed ECT utilization was independently associated with being female, younger age, being employed, nonlocal residence, involuntary admission, having no health insurance, longer length of stay, and the diagnoses of bipolar disorder and major depressive disorder. Use of ECT has increased since 2014 but was not significantly related to readmission 6 months after discharge., Conclusions: Electroconvulsive therapy use appears to be substantially higher in China than in the United States and is associated with indicators of higher rather than lower functioning as reflected by independent associations with youth, employment, and fewer past hospitalizations, but also with behavioral noncompliance as reflected by involuntary admission, and has increased in recent years. Understanding United States-China discrepancies may further international understanding of the diverse roles of ECT in psychiatric practice.
