Research progress of adaptive radiotherapy in radiotherapy of nasopharyngeal carcinoma / 国际生物医学工程杂志

Intensity-modulated radiation therapy(IMRT) is currently the main treatment method for nasopharyngeal carcinoma. During radiotherapy for nasopharyngeal carcinoma, factors such as body mass reduction, tumor regression, and organ displacement at risk can affect the precise implementation of radiation therapy. Applying adaptive radiotherapy (ART) technology to optimize the treatment plan at the appropriate timing can reduce the adverse effects caused by the above factors and enhance the accuracy of radiotherapy. There are no uniform standards for the necessity, timing, and case selection of ART. In this review, the research progress of ART in the radiotherapy of nasopharyngeal carcinoma in recent years was reviewed to provide a reference for further clinical application of ART in nasopharyngeal carcinoma.

Identification of a 17q25.3 duplication in a Chinese patient with global developmental delay and multiple congenital anomalies / 中华医学遗传学杂志

Objective@#To delineate the clinical features, inheritance pattern, and genotype-phenotype correlation of a Chinese patient with a 17q25.3 duplication.@*Methods@#Whole exome sequencing(WES), chromosomal microarray analysis (CMA), chromosomal karyotyping and fluorescence in situ hybridization(FISH) were employed for the analysis of the proband and his family members.@*Results@#A 5.7 Mb duplication at 17q25.3→qter was identified by WES and CMA in the 4-year-old boy with multiple congenital anomalies, which was classified as a clinically pathogenic variant. This duplication was confirmed by FISH, and was inherited from his unaffected mother who carried a balanced translocation. Further study revealed that his grandmother also carried the balanced translocation but had gestated three healthy children and had no abortion history. His uncle also carried the balanced translocation, while his aunt was normal.@*Conclusion@#Above results have enriched the clinical phenotypes of 17q25.3 duplication. Genetic counseling was provided for the family.P4HB, ACTG1, BAIAP2 and TBCD genes may underlie the clinical features for the 17q25.3 duplication.

Current status and reform of practice teaching of radiotherapy technology / 中华医学教育探索杂志

The Major of Medical Imaging Technology (Radiotherapy Technology Orientation) in West China Medical School, Sichuan University, has been devoted to training therapists, dosimetrists, and physicists in tumor radiotherapy, and it is urgently needed to improve the practice ability of interns and standardize the teaching system. In view of the current status of the practice of students in radiotherapy technology, this article analyzes and summarizes the teaching staff construction, teaching contents, teaching methods, and other aspects, finds out the problems and challenges in the current teaching system, and puts forward suggestions for practice teaching reform.

Investigation on the level of hopelessness,anxiety and depression in hospitalized patients with cancer / 中国实用护理杂志

Objective To investigate the suicide related psychological status of cancer patients in hospital. Methods 508 cancer patients in the Affiliated- Tumor- Hospital- of- Guangxi- Medical- University were recruited and using the hospital anxiety and Depression Scale (HADS) and Beck Hopelessness Scale (BHS) for evaluating cancer patients′anxiety, depression, hopelessness. According to age, the patients were divided into three groups, comparing the differences in three groups′scores of anxiety, depression, hopelessness. Results Of all the respondents, there were 38.7% (172/445) patients with anxiety, and 26.3% (117/445) patients with depression, and 59.1% (263/445) patients with different degrees of hopelessness. In the comparison of three groups of patients, anxiety scores existed differences (U=7.083,P 0.05). Conclusions Many people have anxiety / depression in cancer patients, most cancer patients have varying degrees of hopelessness. The health care workers should get attention to these suicide related psychology, take appropriate intervention, in order to avoid the occurrence of hospitalized cancer patients committing suicide.

Investigating the autistic traits in children with attention deficit hyperactivity disorder / 中华行为医学与脑科学杂志

Objective To investigate the autistic symptoms or autistic trait in the children with attention deficit hyperactivity disorder(ADHD) for facilitating the development of appropriate interventions.Methods Sixty-two 6-12-year-old high-functioned autism spectrum disorder (ASD),ADHD and typically developing (TD) children were assessed respectively using Chinese-version social responsiveness scale (SRS),and ADHD core symptoms were assessed in the ADHD children at the same time.Results ASD group＞ADHD group＞ TD group on the SRS total raw score and the five dimensions scores as well(P＜0.01).ASD,ADHD and TD group scored respectively 92.43±19.17,65.66±19.86 and 38.40±10.68 on the SRS total scale.The SRS total raw score of ADHD group exceeded the TD group for 2.55 standard deviant (SD) and with social communication (2.00 SD) and autistic mannerism (2.71 SD) deviating the most.22.58％ (14 out of 62) children with ADHD scored above the threshold on the SRS total raw score which was significantly higher than that in the TD group(P＜0.01).There were nonsignificant differences in the ADHD core symptoms between ADHD± children (with the SRS total raw score ≥85)and ADHD-children(with the SRS total raw score＜85) (P＞0.01).Conclusion Children with ADHD appear more ASD symptoms than the TD children and a considerable proportion of them reach the SRS diagnostic cut-off point.

Investigation of hospitalized patients with cancer of the current sense of hopelessness / 中国实用护理杂志

Objective To investigate the status of hospitalized cancer patients sense of hopelessness.Methods 508 cancer patients in the Affiliated Tumor Hospital of Guangxi Medical University were recruited and divided into the youth group and the middle aged group.Beck Hopelessness Scale (BHS) was assessed to compare the depression degree between the youth group and the middle aged group.Results In general,without a sense of hopelessness in 182 patients (40.9％),mild hopelessness in 178 patients (40.0％),moderate hopelessness in 68 patients (15.3％),severe hopelessness in 17 patients (3.8％).However,no statistical difference was significantly different on the depression degree between the youth group and the middle aged group,while significat difference existed between patients with different dwelling places and treatment time.Conclusions Most cancer patients have different degree of hopelessness.Duration of treatment,dwelling conditions and other factors can affect the patients sense of hopelessness.
