Objective To explore the research hotspots and development trends in the field of cancer treatment in the past decade. Methods The CNKI and Web of Science Core Collection databases were searched for Chinese and English articles related to cancer treatment published over the last 10 years. Bibliometric research methods were employed, including keyword cluster analysis of published literature. Results A total of 45 455 Chinese articles and 866 958 English articles were retrieved. Combining the visualization analysis results and the current research dilemma of tumor treatment revealed that the current research hotspots of tumor treatment domestically and internationally can primarily focus on four key areas. In the realm of targeted therapy, efforts are directed towards the discovery of new drug targets, overcoming resistance to targeted therapy, and the development of monoclonal antibodies and antibody–drug conjugates. In the field of immunotherapy, the emphasis lies in enhancing the response rate to immune checkpoint inhibitors, determining the mechanisms behind resistance to immunotherapy, and improving the safety of treatment. The research in traditional Chinese medicine (TCM) covers evidence-based evaluation studies on TCM treatment, the identification of populations that can gain the most benefit from TCM, and strategies for improving the quality of life. In the area of novel drug development, cutting-edge technologies, such as organoid-based screening for anticancer drugs, synthetic biology, and artificial intelligence, are under investigation. Conclusion New targeted drugs, immune efficacy improvement, multidisciplinary integration, nano-delivery, and TCM innovation are the key research directions in the field of tumor therapy in the future.

OBJECTIVE To construct an evaluation index system for the core competencies of ethics committee members of drug clinical trial institution， providing a basis for optimizing the training system for committee members， improving the quality of ethical review， and fully safeguarding the safety and rights of subjects. METHODS Using methods such as literature research and expert consultation， a preliminary core competency evaluation index system was constructed. The Delphi method was employed to revise and validate it， ultimately forming an evaluation index system for the core competencies of ethics committee members. Based on this system， a questionnaire survey was conducted among 90 ethics committee members from 29 drug clinical trial institutions nationwide， comparing their importance rating and self-assessment scores of the core competency indexes. RESULTS The evaluation system constructed included 4 primary indicators （ethics and professional knowledge， ethics review ability， communication and expression ability， moral integrity and work style） and 39 secondary indicators （familiarity with the content of clinical trial-related laws and regulations， ability to complete project ethics review and identify ethical defects in research protocols within a short period of time， ability to judge the scientific value of clinical research， etc.）. The results of questionnaire survey showed that the interviewed ethics committee members had significant capability gaps in dimensions such as regulatory knowledge， ethical norms， review efficiency， risk judgment， and problem analysis. The differences between the importance rating scores of corresponding secondary indicators and the self-assessment scores were all no less than 0.38. CONCLUSIONS This study has developed a quantifiable and stratified core competency assessment tool for ethics committee members. It can provide a scientific framework for committee member training， qualification certification， and standardized management of ethics committees.

Background The Qingcaosha Reservoir is facing issues of algal blooms and eutrophication, and the resulting increase in the level of chlorination disinfection by-products in the water has been a major concern. Objective To evaluate the impact of "Algae Monitoring and Control Program in Qingcaosha Reservoir" (hereinafter referred to as the program) on the control of trihalomethanes (THMs) in conventional finished water. Methods From 2011 to 2019, water samples were collected from the Lujiazui Water Plant once per season, one sample each time, and the concentrations of four THMs (trichloromethane, dichlorobromomethane, monochlorodibromomethane, and tribromomethane) were measured in the samples. Using 2014 when the program was implemented as a cut-off point, the entire study period was divided into two phases: pre-implementation (2011–2013) and post-implementation(2014–2019). Segmented linear regression with interrupted time series analysis was applied to assess the concentrations and trends of THMs in the finished water before and after the program launch. Results The concentration of total THMs in finished water increased by 1.561 µg·L⁻¹ (P=0.010) for each season of time extension before launching the program. The change in the concentration of total THMs in finished water was not statistically significant after the program launch, but the THMs concentration showed a decreasing trend as the slope was −0.626 (P=0.001). From 2017 until the end of 2019, the average concentration of THMs in finished water of Lujiazui Water Plant dropped to 10 μg·L⁻¹ or less. Conclusions The algae and eutrophication control measures in Qingcaosha Reservoir have achieved good results, controlling THMs in finished water at a low level, and the trend of THMs has changed from a yearly increase pattern before the program to a yearly decrease pattern after the program.

Objective To investigate the relationship between left ventricular hypertrophy(LVH)diagnosed by Peguero-Lo-Presti index and recurrence of paroxysmal atrial fibrillation(AF)after radiofrequency ablation.Methods A total of 652 patients with paroxysmal atrial fibrillation who underwent radiofrequency ablation were selected.According to Peguero-Lo-Presti index,patients were divided into the LVH group(167 cases)and the normal left ventricle group(485 cases).Baseline data were collected,and regular follow-up was performed at 3,6 and 12 months after radiofrequency catheter ablation.The recurrence of AF was assessed.Kaplan-Meier survival curve was used to analyze the recurrence rate of AF in the two groups.Cox proportional hazard model was used to assess risk factors for recurrent atrial fibrillation.Results The median follow-up time was 20.5(15.0,26.0)months.A total of 155 patients(23.8%)developed recurrence of AF,including 95 patients in the LVH group and 60 patients in the LVN group.The recurrence rate without AF was significantly lower in the LVH group than that in the LVN group(64.1%vs.80.4%,Log-rank χ2=26.361,P＜0.01).After adjusting for age,sex,body mass index,hypertension,diabetes,coronary heart disease,cardiac dysfunction,left anteroposterior and posterior atrial diameter,left ventricular end-diastolic diameter,and left ventricular ejection fraction,LVH diagnosed by Peguero-Lo-Presti index was still a risk factor for recurrent AF[HR(95%CI):2.359(1.663-3.345),P＜0.01].Conclusion In patients with paroxysmal AF,LVH diagnosed by Peguero-Lo-Presti index is a risk factor of AF recurrence after radiofrequency catheter ablation.

Purpose To explore the changes of structure of cerebellum,frontal lobe and limbic system(cingulate gyrus,hippocampus and amygdala)in poststroke depression(PSD)via diffusion tensor imaging,and to confirm that cerebellum was involved in the occurrence of PSD,and to study the correlation between cerebellum and traditional depression-related areas such as frontal lobe,limbic system(cingulate gyrus,hippocampus and amygdala).Materials and Methods A total of 39 patients with basal ganglia infarction for the first time from October 2020 to October 2021 in the First Affiliated Hospital of Jinzhou Medical University were evaluated by Hamilton depression scale(HAMD),and all subjects were divided into PSD group(19 cases)and non-PSD group(20 cases),and 20 people with no statistical difference in basic information were randomly selected as the normal control group.The fractional anisotropy(FA)values and apparent diffusion coefficient in region of interest via diffusion tensor imaging were measured.The FA values of lesion and contralateral region of interest were compared among the three groups,and the correlation between FA value and HAMD score was analyzed.Results The FA values of ROI in the prefrontal lobe,hippocampus,cingulate gyrus,corpus callosum,middle cerebellar peduncle,and inferior cerebellar crus in the PSD group were significantly different from those in the non-PSD group and normal control group(t=-0.12--0.06,all P<0.05).The FA values of cerebellum,frontal lobe and limbic system were significantly negatively correlated with HAMD scores(R2adjust=0.954,P<0.05).There was a positive correlation between the FA value of contralateral foot in the cerebellum of PSD patients and that of prefrontal lobe,hippocampus,cingulate gyrus and knee of corpus callosum(r=0.977,0.752,0.637 and 0.539,all P<0.05),respectively.Conclusion PSD patients may have changes in the white matter fiber tracts of the cerebellum,which are associated with traditional depressions.
