Objective To study the SCN1A gene in a family with partial epilepsy with febrile seizures plus ( PEFS+ ) and its characteristics of inheritance. Methods The clinical features of the 2 patients and their father were summarized. All 26 exons of SCN1A gene were screened with denaturing high performance liquid chromatography (DHPLC), and direct sequence analysis was pedormed on those with abnormal elution peak. Pyrosequencing was subsequently performed in those without abnormality in direct sequence analysis. Results The proband and his sister had the phenotype of PEFS+ . The same heterozygous mutations (AS768G) on exon 26 which caused the related amino acid change (Q1923R) were found among them. Their father had frequent febrile seizures (FS) in childhood, and seizures stopped spontaneously. No abnormality was found in direct sequence but mosaic mutation in the same site was discovered with pyrosequencing (mutation quantity was 25% ). Conclusions The mutatin of SCN1A could cause partial epilepsy. PEFS+ could be inherited, the relatives carrying the affected gene may have mild clinical symptoms, possibly resulting from the low concentration of the mutated gene due to mosaic mutation.

Objective To explore how the emotional experience and stress symptoms associated with compassion fatigue emerges,develops and subsides,as well as their coping strategy for compassion fatigue. Methods By purposive sampling integrating with snowball sampling method,semi-structured reviews with open-ended questions were conducted among 47 registered nurses who are working or have ever being in clinical frontline department to gain their in-depth views about compassion fatigue. Theme analysis was used to analyze the data.Results In emotional experience,two main themes were extracted:positive and negative emotion. Six subthemes including happy,high spirits,interests,sense of self-value,sense of achievement and occupational pride were extracted from positive emotion. While nine subthemes including compassion,grief,depressed mood,irritability,guilty,powerlessness,apathy,fear and anxiety were extracted from the negative emotion. Conclusions Clinical nurses are lack of basic knowledge about compassion fatigue,and their work and life are influenced by compassion fatigue. It should be emphasized and enhanced that domestic hospital administrators should identify and take precaution against compassion fatigue.

Objective:To investigate the standardization construction of nursing information terminologies in Guizhou Province and provide reference for constructing a standard nursing terminology system in Guizhou Province.Methods:Using the convenient sampling method, a total of 153 nursing managers from hospitals at all levels in Guizhou Province were selected as the research objects in June, 2021. The research objects were surveyed using a self-developed survey questionnaire on the current status of standardized terminology construction for hospital nursing information. The questionnaire consisted of two parts. The first part was the basic information of the hospital and the general information of the person in charge of nursing information. The second part was the construction of standardized terminology for nursing information, including three dimensions, such as the basic dataset of nursing electronic medical records, the shared document of nursing electronic medical records and the construction of nursing information terminologies interconnection. Multiple linear regression analysis was used to analyze the influencing factors of standardized construction of nursing information terminologies. A total of 153 questionnaires were distributed in this study and 148 valid questionnaires were collected, with an effective response rate of 96.73% (148/153) .Results:The total score of the survey questionnaire on the standardization of nursing information terminologies construction in 148 hospitals in Guizhou Province was (102.22±24.42) . The basic dataset dimension score of nursing electronic medical records was (60.35±13.32) , the shared document dimension score of nursing electronic medical records was (27.78±19.08) and the dimension score of nursing terminology interconnection construction was (14.08±2.71) . The results of multiple linear regression analysis showed that hospital level and whether nursing managers had received terminology training were the influencing factors for the score of hospital nursing information standardization terminology construction ( P<0.05) . Conclusions:The standardization construction of nursing information terminologies in medical institutions in Guizhou Province is still at the primary level of information construction. The insufficient attention paid by secondary hospital managers to the standardization construction of nursing information terminologies and the lack of understanding of standardized nursing terminology by nursing information managers are important influencing factors.
