Objective To explore the effects of behavioral intervention on mental heath and quality of life of inpatients with coronary heart disease. Methods Eighty cases with coronary heart disease were randomly divid-ed into intervention group(n=40) and the drug treatment group(n=40). SF-36,SCL-90,EPQ,HAMA,HAMD were applied to assess the mental health state and quality of life. Results After 6-months, the score of SF-36,SCL-90,EPQ,HAMA, HAMD,and N score of EPQ in intervention group were more significantly proved than the drug treatment group SF-36:(84.7±16.2)vs(68.3±10.6); P <0.01; SCL-90:(83.5±4.2)vs(148.6±3.2)], P<0.05;EPQ-N:(43.8±4.2)vs(52.8±3.1), P<0.01;HAMA:(10.4±3.4)vs(15.1±5.1), P <0.01; HAMD: (11.4±3.8) vs (17.9±4.6), P< 0.01). Conclustion Behavioral intervention effectively im-proves mental state and quality of life of patients with coronary heart disease.

Objective To evaluate the effect of applying modified clinical pathway management model in psychiatric nursing practice teaching.Methods Totally 196 nursing students joining in the psychiatric nursing clinical practice were divided into control group (n=102) and intervention group (n=94), according to their internship time.The control group followed the traditional teaching model, while the intervention group received training based on the modified clinical pathway model, in which the students were involved in to specify the training plan and generate the sequence and timing of actions necessary to achieve goals.The examination, mutual behavior rating and total satisfaction investigations’ results were compared between the two groups at the end of the internship.Results Both the exam scores and the satisfactions in the intervention group were significantly higher than that in the control group (P<0.01).Two factors were extracted by exploratory factor analysis, factor one included:teaching skills, professional moral, level of expertise, theoretical score, work attitude, operating score; factor two included: teaching management capability, lecture score, behavioral norms, satisfaction evaluation ( student to teacher ) .Conclusions The application of clinical pathway in psychiatric nursing practice can standardize and explicit training protocol, improve the effect of internship.It is a kind of teaching model worth spreading.

【Objective】 To assess the trend of hepatitis B virus (HBV) prevalence and associated risk factors among voluntary blood donors in Guangzhou area from 2011 to 2020, and to explore the impact of hepatitis B vaccination in neonates on the risk of HBV infection. 【Methods】 Blood samples of 2 624 434 voluntary blood donors from 2011 to 2020 in Guangzhou were tested by HBV surface antigen (HBsAg) enzyme-linked immunosorbent assay (ELISA) reagents twice and nucleic acid test (NAT) reagent once. Samples reactive to ELISA twice, or ELISA once + NAT were considered as HBV infection. The gender, age, ethnicity and region of HBV infected blood donors were collected, and the incidence of HBV infection in blood donors born before and after 1992 (when HBV vaccination was conducted in neonates) was compared. The trend and risk factors of HBV infection in blood donors in Guangzhou from 2011 to 2020 were analyzed. 【Results】 An overall HBV prevalence of 0.75% was found in voluntary blood donors in Guangzhou area from 2010 to 2020, showing an overall downward trend(P<0.05). HBV prevalence was lower in blood donors born after 1992 (0.49 %, 4 825/98 5362) than prior to 1992 (P<0.05). HBV prevalence in male blood donors (0.89%, 15 049/1 695 062) was significantly higher than that in female blood donors (P<0.05). HBV prevalence in blood donors aged 18~25(0.52%, 6 337/1 219 282)was lower than that in other age groups (P<0.05). HBV prevalence was similar in donors resident in Guangdong and other provinces(P>0.05), but both were significantly higher than that in Hong Kong, Macao, Taiwan and foreign countries (P<0.05). HBV prevalence in Han nationality donors was significantly higher than the ethnic minority donors (P<0.05). Gender, age, ethnicity and birth vaccination are the main risk factors for HBV infection among blood donors. 【Conclusion】 The overall HBV prevalence among voluntary blood donors in Guangzhou area from 2011 to 2020 has shown a decreasing trend, and differences have been found in gender, age, region, ethnicity and birth vaccination, which is helpful to formulate targeted recruitment strategies, thus reducing the risk of transfusion transmitted HBV.

[Objective] To analyze the influence of the cycle length of hepatitis B surface antigen (HBsAg) double reagent positive samples collected from voluntary blood donors in Guangzhou on the detection results. [Methods] A total of 127 044 blood samples from voluntary blood donors at Guangzhou Blood Center from August 10 to December 9, 2023 were selected. Two ELISA reagents were used for HBsAg detection, and samples with HBsAg double reagent positive and S/CO values<10 were tested continuously for 7 days to observe the changes in their S/CO values. [Results] A total of 505 HBsAg double reagent positive samples were detected, of which 52 had S/CO values less than 10. After 7 consecutive days of uninterrupted testing, the S/CO values of Wantai (median 5 decreased to 3) and Xinchuang (median 5 decreased to 3) showed an overall downward trend, and the HBsAg missed detection rate showed an upward trend (from 0 on the first day to 1/10 000 on the seventh day). A total of 13 cases had negative double reagent test results within the 7-day testing cycle. [Conclusion] With the extension of the detection cycle, the S/CO value of HBsAg detection shows a downward trend, and the missed detection rate of HBsAg shows an upward trend. Samples used for HBsAg detection should be tested promptly after sampling to improve the quality of blood testing.
