Objective:To investigate the application effect of medical failure modes and effects analysis(FMEA)in reducing the inci-dence rate of catheter dislodgement in patients in the post-anesthesia care unit(PACU).Methods:A retrospective study was con-ducted among 469 PACU patients in our hospital from January 2023 to June 2024.According to the application time of FMEA,the pa-tients were divided into routine group(234 PACU patients who did not receive FMEA from January to June 2023)and FMEA group(235 PACU patients who received FMEA from July 2023 to June 2024).The two groups were compared in terms of the incidence rate of catheter dislodgement,risk priority number(RPN)coefficients(including professional knowledge,risk awareness,and intervention guidance),the quality of recovery of consciousness(including the time to complete recovery of consciousness and the length of stay in the PACU),and the degree of satisfaction with nursing(including risk management,nursing services,and nursing techniques).Results:The FMEA group had a significantly lower incidence rate of catheter dislodgement than the routine group[0.43%(1/235)vs.2.99%(7/234),the difference was statistically significant(χ2=4.604,P=0.032)].Compared with the routine group,the FMEA group had significantly lower RPN coefficients of risk awareness t=52.518,professional knowledge t=49.641,and intervention guidancet=61.592(P<0.001).Compared with the routine group,the FMEA group had significantly shorter time to complete recovery t=18.087 of consciousness and length of stay in the PACUt=15.710(P<0.001).The FMEA group had a significantly higher degree of satisfaction with nursing than the routine group in terms of risk management t=19.794,nursing services t=10.825,and nursing techniques t=14.555(P<0.001).Conclusion:The application of FMEA manage-ment in PACU patients can reduce the incidence rates of catheter dislodgement and risk events and improve the quality of recovery of consciousness and the degree of satisfaction with nursing,and there-fore,it has important clinical significance.

Objective:To compare the differences in prefrontal activation patterns between major depressive disorder and schizophrenia during the eye basic emotion discrimination task (EBEDT).Methods:Using functional near infrared spectroscopy (fNIRS) technology and block design, the changes of prefrontal lobe oxyhemoglobin (Oxy-Hb) concentrations under EBEDT in 40 patients with major depressive disorder, 47 patients with schizophrenia and 55 normal controls were compared. Subsequently, employing years of education as a covariate, an analysis of covariance was performed on the EBEDT behavioral results and the changes in prefrontal Oxy-Hb concentrations in the three groups.The statistical software was SPSS 25.0.Results:(1)The correct number of EBEDT in schizophrenia group (13.93±7.67) was significantly lower than that in major depressive disorder group (19.26±8.07) and normal control group (21.79±6.36)(both P<0.05), and the EBEDT reaction time in schizophrenia group ((3.97±1.77) s) was significantly longer than those in major depressive disorder group ((3.21±1.27) s) and normal control group ((2.63±0.62) s)(both P<0.05).(2)During the EBEDT task block, the normal control group showed increased activation levels in the frontal polar region, Broca's area, anterior motor cortex and supplementary motor area (SMA) compared with the control block( t=2.02-3.18, all P<0.05); and the schizophrenia group showed increased activation levels in the frontal eye field compared with the control block( t=2.26, P=0.03); while the major depressive disorder group exhibited decreased activation levels in the entire prefrontal lobe compared with the control block( t=-3.47--2.34, all P<0.05). (3)During the emotion recognition task of EBEDT, the activation levels of the frontal polar area (ch37), dorsolateral prefrontal cortex (ch31), Broca's area (ch49, ch51, ch53), and SMA (ch1, ch47, ch52) were significantly different among the major depressive disorder, schizophrenia and normal controls( F=3.23-5.53, all P<0.05). Further pairwise comparisons showed that the activation levels in all the above pathways were lower in the major depressive disorder group than those in the normal control group, and the activation levels in Broca's area (ch53) and SMA area (ch52) were lower in the schizophrenia group than those in the normal control group, while the activation levels in the frontal polar area (ch37) and Broca's area (ch49) were lower in the major depressive disorder group than those in the schizophrenia group(all P<0.05). Conclusions:In EBEDT, the activation patterns of the prefrontal cortex are different between patients with major depressive disorder and patients with schizophrenia. Patients with major depressive disorder have a decrease in prefrontal cortex activation, while patients with schizophrenia have an increase in the frontal eye field activation.The activation levels in prefrontal cortex of both patients group are lower than that of normal controls. Meanwhile, the prefrontal cortex activation level of patients with major depressive disorder is lower than that of patients with schizophrenia.

Retinoblastoma (RB), the most common primary intraocular malignancy in infants and young children, poses a serious threat to visual function and the life of children when systemic metastasis occurs. Circular RNA (circRNA) is a recently discovered class of non-coding RNA that mainly functions as competitive endogenous RNA by regulating gene expression through competing with microRNA. circRNA can function as oncogenes or tumor suppressors, regulating various biological processes in RB cells, such as proliferation, migration, apoptosis, autophagy, and drug resistance, thereby providing new therapeutic targets for RB. In addition, the differential expression of circRNA in tumor tissues or exosomes is expected to be a potential biomarker for RB. Further studies and explorations are still needed for the functions and regulatory mechanisms of circRNA in RB to reveal their precise roles in organisms and potential clinical applications.

Through the exploration of the Xuanfu theory,this article analyzes and summarizes the pathogenesis and treatment of depression,and explores the application of wind medicine in the treatment of depression in traditional Chinese medicine.On the basis of sorting out the connotation of Xuanfu theory and the historical changes of the wind medicine,it is concluded that the main pathogenesis of depression is Xuanfu opening and closing block,obstruction of qi,blood and body fluid,and dysfunction of mental machinery.The basic therapeutic method is to open the Xuanfu to treat depression,and the syndrome differentiation is assisted by regulating qi,resolving turbidity,promoting blood circulation and tonifying deficiency.The efficacy of the wind medicine and the effect of drug components were summarized,and the application of the wind medicine in the treatment of depression was discussed.The efficacy of the wind medicine and the effect of drug components were summarized,and the medication regularity of the wind medicine in the treatment of depression was discussed.Through the Xuanfu theory to understand depression again,and to recognize the wind medicine in the treatment of depression has a unique role,but also can help other drugs,significantly enhance its effect in the treatment of depression.

This study was aimed to build up a diagnosis and treatment procedure of traditional Chinese medicine (TCM) for HIV/AIDS headache. Domestic and foreign articles correlated to HIV/AIDS headache diagnosed and treat-ed by TCM were summarized. The specialist questionnaire of clinical diagnosis and treatment standard operating pro-cedures of TCM for HIV/AIDS headache was designed by focus group discussions. And the national specialist ques-tionnaire survey was carried out twice. The results showed that the standard operating procedure of TCM clinical di-agnosis, treatment, nursing and therapeutic efficacy assessment for HIV/AIDS headache was preliminarily established. It was concluded that this regulation identified concept, etiology and pathogenesis of HIV/AIDS, established TCM standard diagnosis and treatment service. It also demonstrated features of propaganda and education, follow-ups, con-secutive diagnosis and treatment inside or outside the hospital.

This study was aimed to establish traditional Chinese medicine (TCM) diagnosis and treatment procedure of varicella zoster virus (VZV) in AIDS, and to construct questionnaires for key points and revision of the procedure. The TCM draft of diagnosis and treatment procedure for VZV in AIDS was established through literature retrieval and peer review. Two rounds of surveys were carried out to investigate the confirmation and advice of in-group specialist to key points of TCM or integrative medicine draft including diagnosis, treatment and nursing. Then, diagnosis and treatment procedure were revised according to survey results. The results showed that the recovery of complete ques-tionnaires in the first-round survey was 96%. More confirmation of specialists were given to concept, clinical feature, cause, mechanism, case history and general examination, diagnostic criteria, syndrome differentiation and treatment of dampness-heat of liver channel syndrome, skin, dietary and psychological nursing, treatment course and therapeutic effect standard. The coefficient of variations (CVs) of experiential effective recipe, moxibustion and massage, auxiliary examination, syndrome differentiation and treatment of dampness stagnancy due to spleen deficiency syndrome and qi stagnation and blood stasis syndrome, and western medicine treatment were large. The weight coefficients of all items were within 0.043 6 and 0.046 2. The Cronbach Coefficient Alpha (CCA) was 0.996 and the split-half reliability R was 0.86. Recovery of complete questionnaires in the second-round survey was 100%. More confirmation of special-ists were given to outline, cause, mechanism, case history and general examination, diagnostic criteria, syndrome dif-ferentiation and treatment of three syndromes, experiential effective recipe, skin, dietary and psychological nursing. The CV was 0. The CV of auxiliary examination, moxibustion and massage was 0.063 8, which was less than those of first-round survey. The consistency of specialist was relatively increased. The weight coefficients of all items in the second-round survey were within 0.058 2 and 0.059 0. The CCA was -0.041 and the split-half reliability R was 0.79. A new revised procedure was preliminarily established according to results of two rounds of surveys. It was concluded that the activeness, concentration and coordination of specialists were good in two rounds of surveys. Con-sensus in key points of the procedure draft was reached including diagnosis, treatment and nursing.
