BACKGROUND: Molecular subtyping is an essential complementarity after pathological analyses for targeted therapy. This study aimed to investigate the consistency of next-generation sequencing (NGS) results between circulating tumor DNA (ctDNA)-based and tissue-based in non-small cell lung cancer (NSCLC) and identify the patient characteristics that favor ctDNA testing. METHODS: Patients who diagnosed with NSCLC and received both ctDNA- and cancer tissue-based NGS before surgery or systemic treatment in Lung Cancer Center, Sichuan University West China Hospital between December 2017 and August 2022 were enrolled. A 425-cancer panel with a HiSeq 4000 NGS platform was used for NGS. The unweighted Cohen's kappa coefficient was employed to discriminate the high-concordance group from the low-concordance group with a cutoff value of 0.6. Six machine learning models were used to identify patient characteristics that relate to high concordance between ctDNA-based and tissue-based NGS. RESULTS: A total of 85 patients were enrolled, of which 22.4% (19/85) had stage III disease and 56.5% (48/85) had stage IV disease. Forty-four patients (51.8%) showed consistent gene mutation types between ctDNA-based and tissue-based NGS, while one patient (1.2%) tested negative in both approaches. Patients with advanced diseases and metastases to other organs would be suitable for the ctDNA-based NGS, and the generalized linear model showed that T stage, M stage, and tumor mutation burden were the critical discriminators to predict the consistency of results between ctDNA-based and tissue-based NGS. CONCLUSION ctDNA-based NGS showed comparable detection performance in the targeted gene mutations compared with tissue-based NGS, and it could be considered in advanced or metastatic NSCLC.

The inclusive indicator dimension included 6 second-level indicators, and the proportion of personal health expenditure to total health expenditure had the highest weight. The sustainability indicator dimension included 10 second-level indicators, and the proportion of government health expenditure in fiscal expenditure had the highest weight.Conclusions:The indicator system constructed in this research could provide certain guidance and reference for promoting the construction of common prosperity in health, and provide some reference for follow-up research in this field.

Objective:To evaluate the clinicopathologic characteristics and outcomes of HIV-negative plasmablastic lymphoma (PBL) .Methods:Medical records of 15 patients diagnosed with HIV-negative PBL in Changhai Hospital between January 2013 and August 2019 were reviewed, and clinicopathologic characteristics and outcomes were analyzed.Results:Median age was 59 years (range: 17-69) . All patients had extranodal involvement. According to the Cotswolds-modified Ann Arbor staging system, 1 (6.7%) , 2 (13.3%) , 3 (20.0%) , and 9 (60.0%) patients were classified as at Ⅰ,Ⅱ,Ⅲ and Ⅳ, respectively. Plasmablast and immunoblast proliferations were typical manifestations of PBL. Immunohistochemical staining showed tumor cells were diffusely positive for plasma cell markers CD38, CD138, and Mum-1, while negative for B cell markers CD20, CD10, PAX-5, and BCL-6. Median Ki-67 index was 80% (70%-90%) . Epstein-Barr virus-encoded RNA (EBER) expression was detected in 3 patients, and 1 of them was positive. All patients received chemotherapy, 80% combined with bortezomib as the first line, and responses were observed in 8 patients (6 complete and 2 partial responses) . Median progression-free survival (PFS) and overall survival (OS) were 6.8 (95% CI 2.5-11.1) months and 17.9 (95% CI 5.6-30.2) months, the 3-year PFS and OS rates were 21.2% (95% CI 1.4%-56.8%) and 38.5% (95% CI 12.0%-65.0%) , respectively. Conclusion:HIV-negative PBL with high invasiveness is extremely prone to extranodal involvement and most patients were at the advanced stage. Patients receiving an intensive therapy combined with bortezomib and bridged autologous stem cell transplantation may improve long-time survival.

Objective? To retrieve and analyze the related researches on intensive care unit(ICU) physical environment from 2013 to 2017, and to provide reference for further improvement of the physical environment and quality of medical and nursing care in ICU. Methods? Relevant literature on ICU physical environment included from 2013 to 2017 by the China National Knowledge Infrastructure(CNKI), Wanfang Data Knowledge Service Platform, VIP Database for Chinese Technical Periodicals, Sinomed, Pubmed, Web of Science,and Scopus database were retrieved and analyzed bibliometrically on the internal and external features of the articles by Excel and CiteSpace software. Results? A total of 287 domestic and oversea papers on ICU physical environment were retrieved, the number of published articles showed an overall stable trend. The biggest number of published articles went to Guangdong Province, accounting for 14.1% of the articles in Chinese language. The United States had the biggest number of published papers in English language (43.8%). Literature journals mainly focused on infection control, critical medicine and critical care nursing journals, with the largest number of articles published by a single author(23.0%). The main types of research were clinical research (79.1%), fund-supported literature accounted for 26.5% of all the articles, and research directions were mainly about infection (40.0%), "nosocomial infection" and "pathogenic bacteria", "environment" and"object surface", "premature infant" and "growth and development", "sleep" and "noise" were closely related. Conclusions? The researches on ICU physical environment involves aspects including object surface, noise, light, air quality, temperature and ward design. Infection control in ICU environment and the influences of ICU physical environment on patient's biological rhythm and the growth and development of preterm infants are hot research issues in recent years. However, the geographical distribution of research is not balanced,and the overall quality of research evidence needs to be improved.

Mood disorders/psychosis have been associated with dysfunctions in the default mode network (DMN). However, the relative contributions of DMN regions to state and trait disturbances in pediatric bipolar disorder (PBD) remain unclear. The aim of this study was to investigate the possible mechanisms of PBD through brain imaging and explore the influence of psychotic symptoms on functional alterations in PBD patients. Twenty-nine psychotic and 26 non-psychotic PBD patients, as well as 19 age- and sex-matched healthy controls underwent a resting-state functional MRI scan and the data were analyzed by independent component analysis. The DMN component from the fMRI data was extracted for each participant. Spearman's rank correlation analysis was performed between aberrant connectivity and clinical measurements. The results demonstrated that psychotic PBD was characterized by aberrant DMN connectivity in the anterior cingulate cortex/medial prefrontal cortex, bilateral caudate nucleus, bilateral angular gyri, and left middle temporal gyrus, while non-psychotic PBD was not, suggesting further impairment with the development of psychosis. In summary, we demonstrated unique impairment in DMN functional connectivity in the psychotic PBD group. These specific neuroanatomical abnormalities may shed light on the underlying pathophysiology and presentation of PBD.

OBJECTIVE： To explore the role of clinical pharmacists on anlotinib-induced ADR in patients with advanced lung cancer， and to provide reference for safe drug use in clinic. METHODS： For 3 typical cases of ADR caused by the treatment of advanced lung cancer with anlotinib， clinical pharmacists provided pharmaceutical care to patients from the aspects of the use of anlotinib， medication education， the prevention and treatment of ADR， and assisted clinicians to solve ADR related to anlotinib such as hemoptysis， liver injury， elevated blood pressure， proteinuria， etc. RESULTS： For one case of anlotinib-induced hemoptysis， clinical pharmacists analyzed that the degree of hemoptysis was mild. They suggested that anlotinib should be discontinued and treated symptomatically with cough relief and hemostasis. If necessary， pituitrin should be added. Anlotinib could be continued after hemoptysis control， which doctors adopted. No hemoptysis occurred during the treatment period. For the case of anlotinib caused liver function damage， clinical pharmacists analyzed it as mild cholestasis type. They suggested that no discontinuation of anlotinib should be given and adenosylmethionine treatment should be given， which doctors adopted. After 5 days of treatment， the patients’ liver function returned to normal， and no obvious liver function damage was found in the later period. For the case of anlotinib induced hypertension with proteinuria， the patient had a history of hypertension. For hypertension， clinical pharmacists strengthened medication education for patients， instructed patients to adjust diet， appropriately activities， reduce mental stress and monitor blood pressure. The psychological intervention and other non-drug antihypertensive effects were poor， and then clinical pharmacists suggested to modify the antihypertensive treatment for patients. Doctors adopted it and changed the former antihypertensive drug nitrendipine to angiotensin receptor blocker valsartan. After 2 weeks of treatment， blood pressure returned to normal. For urinary protein， clinical pharmacists recommend to discontinue the use of anlotinib， and the urinary protein returned to normal after 2 weeks. Clinical pharmacists recommend to reduce the dose of anlotinib to continue treatment， which the doctors adopted. No abnormal urinary protein was found in the later review. CONCLUSIONS： Clinical pharmacists should actively provide pharmaceutical care for lung cancer patients treated with anlotinib， and strengthen medication education so as to promote rational drug use in clinic.

OBJECTIVE: The aims of the present study were to explore the occurrence of childhood trauma and importantly to determine the impacts of childhood trauma on psychosocial features in a Chinese sample of young adults. METHODS: A survey was carried out in a group of 555 university students by using Childhood Trauma Questionnaire (CTQ), Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS), Dysfunctional Attitudes Questionnaire (DAS), Eysenck Personality Questionnaire (EPQ), and Social Support Rating Scale (SSRS). The moderate-severe cut-off scores for CTQ were used to calculate the prevalence of childhood trauma, and then psychosocial features were compared between individuals with and without childhood trauma. RESULTS: A proportion of 18.6% of university students had self-reported childhood trauma exposures. Subjects with childhood trauma reported higher scores of SDS, SAS, DAS, and psychoticism and neuroticism dimensions of EPQ (t=4.311–5.551, p < 0.001); while lower scores of SSRS and extraversion dimension of EPQ (t=-4.061– -3.039, p < 0.01). Regression analyses further revealed that scores of SAS and DAS were positively (Adjusted B=0.211–0.230, p < 0.05), while scores of SSRS were negatively (Adjusted B=-0.273– -0.240, p < 0.05) associated with specific CTQ scores. CONCLUSION: Childhood trauma is still a common social and psychological problem. Individuals with childhood trauma show much more depression, anxiety, distorted cognition, personality deficits, and lower levels of social support, which may represent the social and psychological vulnerability for developing psychiatric disorders after childhood trauma experiences.
