ObjectiveThis study aimed to explore the correlation between the quality of life （QOL） and different traditional Chinese medicine （TCM） syndromes in patients with myasthenia gravis （MG）， identifying potential influencing factors to provide new insights for clinical interventions and improving the QOL of patients with MG. MethodsA questionnaire survey was conducted on 93 adults with MG who visited the Department of Neurology at the Affiliated Hospital of Changchun University of Chinese Medicine from March 2023 to January 2024. Statistical analysis was performed on the clinical data collected using SPSS 24.0 software. ResultsAmong the 93 patients with MG， the average score for myasthenia gravis quality of life-15 （MGQOL-15） was 17.65±6.27， and that for the 36-item short form health survey （SF-36） was （106.13±11.83） scores. The QOL was rated as good for 16 patients and moderate for 77 patients. There were no statistically significant differences in the scores of MGQOL-15， SF-36， and their individual scales by gender or education level. Age showed statistically significant differences in MGQOL-15 and the role physical （RP） scale （P<0.05）， and occupational type showed significant differences in the vitality （VT） scale （P<0.01）. The Myasthenia Gravis Foundation of America （MGFA） classification had statistical significance on the total SF-36 score （P<0.01）， VT scale （P<0.01）， role emotional （RE） scale （P<0.05）， social functioning （SF） scale （P<0.05）， and physical functioning （PF） scale （P<0.01）. Among patients with different TCM syndromes， there were significant differences in MGQOL-15 scores （F=4.919， P<0.01）. Moreover， significant differences were observed in SF-36 scores （P<0.01）， VT scale （P<0.01）， RE scale （P<0.05）， mental health （MH） scale （P<0.01）， and SF scale （P<0.05）. ConclusionFactors affecting the QOL of patients with MG include age， occupational type， and clinical classification of MG. Specifically， a greater impact on the QOL of older patients is observed， while physical laborers have a poorer QOL compared to non-physical laborers. Patients classified as MGFA type Ⅱ and higher have a poorer QOL. Additionally， there is a potential correlation between the QOL and TCM syndromes， with patients presenting with spleen and kidney Qi deficiency having a lower QOL than those with spleen and stomach Qi deficiency or Qi and Yin deficiency， which is particularly evident in the VT， RE， MH， and SF scales.

Objective To explore potential categories of post-stroke depression in acute-phase stroke patients and its correlation with the degree of neurological deficits,and to provide references for healthcare professionals in developing targeted interventions.Methods Using convenience sampling,patients with acute stroke who were hospitalized in neurological ward of 2 tertiary general hospitals in Henan Province from January to April 2024 were selected as the survey participants.The investigation was conducted using the General Information Questionnaire,the National Institute of Health Stroke Scale,and the Patient Health Questionnaire-9.The correlation between potential categories of post-stroke depression and the degree of neurological deficit was analysed using unordered multiclassified logistic regression.Results Post-stroke depression score was 10.22±3.61 in 193 acute-phase stroke patients,and post-stroke depression could be categorized into 3 potential categories,namely"low depressive symptoms"(44.6％),"melancholic depression"(15.0％),and"atypical depression"(40.4％).There was a significant difference in the degree of neurological deficits(H=38.074,P＜0.001).Compared with severe neurological deficits,patients with mild deficits were more likely to be categorized as"melancholic depression"(OR=0.016,P=0.001)and"atypical depression"(OR=0.040,P＜0.001),and patients with moderate deficits were more likely to be classified as"atypical depression"(OR=0.085,P=0.001).Conclusion Post-stroke depression in acute-phase stroke patients has obvious categorization characteristics,and it is recommended that healthcare professionals should pay more attention to patients with different degrees of neurological deficits and adopt targeted interventions according to the different categories of post-stroke depression in order to alleviate their depressive symptoms.

With the continuous development of surgery,the amount of Da Vinci robot surgery has increased year by year,and Da Vinci robot has been widely used in the field of surgery.However,due to its structural characteristics,robot surgical instruments are difficult to clean after contamination,which poses a great challenge to the cleaning technology of nurses in central sterile supply department(CSSD).At present,there are still some problems in the cleaning quality management of Da Vinci robotic surgical instruments,such as inadequate pre-treatment,non-standard manual cleaning process,and inconsistent cleaning quality evaluation methods,which bring great hidden dangers to patients'medical safety.Therefore,scientific and effective cleaning quality control is very important to prevent nosocomial infection and ensure the life safety of patients.This paper reviews the cleaning process and quality control on Da Vinci robotic surgical instruments by consulting,screening,sorting and summarizing domestic and foreign relevant literature of the cleaning and management,and combining with the actual clinical work of the disinfection supply center,and aims to provide theoretical references for the formulation of guidelines and clinical practice for the personnel of CSSD.

Abdominal aortic aneurysm (AAA) is a life-threatening large-vessel disease closely associated with immune and inflammation-related mechanisms. During the development of AAA,innate immune cells play a pivotal role in the immune-mediated inflammatory infiltration and destruction of the aortic wall. These cells include neutrophils,monocytes,macrophages,dendritic cells,mast cells,natural killer cells,innate lymphoid cells,and invariant natural killer T cells. Although various immune cells have been progressively identified in the study of AAA,their activation mechanisms and functions remain to be further elucidated. This article summarizes the roles of innate immune cells in the progression of AAA and discusses the regulatory mechanisms of their activation in this disease,providing a theoretical basis for research on AAA progression.

Objective:To rapidly evaluate the level of healthcare resource demand for laboratory testing and prevention and control of corona virus disease 2019 (COVID-19) in different epidemic situation, and prepare for the capacity planning, stockpile distribution, and funding raising for infectious disease epidemic response.Methods:An susceptible, exposed, infectious, removed infectious disease dynamics model with confirmed asymptomatic infection cases and symptomatic hospitalized patients was introduced to simulate different COVID-19 epidemic situation and predict the numbers of hospitalized or isolated patients, and based on the current COVID-19 prevention and control measures in China, the demands of resources for laboratory testing and prevention and control of COVID-19 were evaluated.Results:When community or local transmission or outbreaks occur and total population nucleic acid testing is implemented, the need for human resources is 3.3-89.1 times higher than the reserved, and the current resources of medical personal protective equipment and instruments can meet the need. The surge in asymptomatic infections can also increase the human resource demand for laboratory testing and pose challenge to the prevention and control of the disease. When vaccine protection coverage reach ≥50%, appropriate adjustment of the prevention and control measures can reduce the need for laboratory and human resources.Conclusions:There is a great need in our country to reserve the human resources for laboratory testing and disease prevention and control for the response of the possible epidemic of COVID-19. Challenges to human resources resulted from total population nucleic acid testing and its necessity need to be considered. Conducting non-pharmaceutical interventions and encouraging more people to be vaccinated can mitigate the shock on healthcare resource demand in COVID-19 prevention and control.

Objective To investigate the incidence of dyssomnia,posttraumatic stress disorder (PTSD) and their relationship in earthquake survivors in Jiangyou and Beichuan area,and supply evidence for prediction and treatment of PTSD.Methods Dyssomnia was accessed by Pittsburgh Sleep Quality Index (PSQI),posttraumatic symptoms were measured using the PTSD Checklist-Civilian Version (PCL-C).Results The prevalence of dyssomnia was 33.8％,the PTSD was 7.5％.In good sleep group,the number of people who didn't suffer from PTSD was 358 (96.5％),the number of people who suffered from PTSD was 13 (3.5％); In dyssomnia group,the number of people who didn't suffer from PTSD was 160(84.7％),the number of people who suffer from PTSD was 29(15.3％).In PTSD negative group,the number of people who had good sleep was 358 (69.1％); the number of people who had dyssomnia was 160 (30.9％).In PTSD positive group,the number of people who had good sleep was 13(31.0％),the number of people who had dyssomnia was 29(69.0％).The correlation analysis showed that total scores of PCL-C were positively related with total score of PSQI.The logistic regression showed that the very hard-hit area,serious posttraumatic symptoms,were the dangerous factors of dyssomnia.Conclusions The dyssomnia and PTSD are still common among victims two years after 5.12 earthquake.PTSD can cause sleeping problem,meanwhile sleep problem could increase the risk of PTSD.

Aim To explore the role of heat shock protein 90(Hsp90)in hydrogen sulfide-induced protection against PC12 cells injuries elicited by cobalt chloride(CoCl_2).Methods Hydrogen sulfide preconditioning against CoCl_2-induced injury model was set up in PC12 cells.Cell viability was tested by using cell counter kit-8.Morphological changes in apoptotic PC12 cells were detected by Hoechst 33258 staining and photofluorography.Apoptotic rate was evaluated by propidium iodide(PI)staining and flow cytometry(FCM).The expression of Hsp90 was evaluated by Western blot.Results Hsp90 expression was upregulated after treatment with 400 μmol·L~(-1) sodium hydrosulfide(a H_2S donor),peaking at 3 h,returning to the basal level at 24 h.Furthermore,H_2S preconditioning obviously enhanced the upregulation of Hsp90 expression induced by CoCl_2.H_2S preconditioning markedly protected PC12 cells against injuries induced by CoCl_2,increasing the viability of cells and decreasing the percentage of apoptotic cells.17-allylamino-17-demethoxygeldanamycin(17-AAG),an inhibitor of Hsp90,antagonized H_2S preconditioning-induced Hsp90 activation and the adaptive cytoprotection.Conclusion H_2S can protect PC12 cells against CoCl_2-induced injuries,and upregulating the expression of Hsp90 may be one of the mechanisms underlying cytoprotection induced by H_2S preconditioning.
