Objective:To design a management system of internet of things(IoT)smart operation room based on business process reconstruction theory,and explore the application effect of that in improving management effectiveness for operation room.Methods:Aimed at the existing problems of key points in the management for operation room,the process was reconstructed on the basis of the original information system,relevant systems,workflows and standards of operation room of Fuwai Hospital of Medical Sciences and Peking Union Medical College.Then,a management system of IoT smart operation room based on business process reconstruction theory was designed.The surgical data of 13159 patients who underwent relevant operation of cardiovascular surgery from January to December 2022 were selected,and they were divided into"before-application"group(6 483 cases)and"after-application"group(6 676 cases)according to the point before and after the system was applied.Some indicators'data,which included scheduling management situation of picking up and dropping off patients by medical auxiliaries,duration of preparing anesthesia,duration of preoperative waiting,interval duration of continuous surgery and usage amount of surgical gowns under same amount of surgery,between two groups were compared.Results:The transportation efficiency of patients who underwent surgery after system was applied was(1.38±0.09)surgeries/h,which was higher than(0.99±0.09)surgeries/h before it was applied,and the difference was statistically significant(t=6.604,P<0.001).The satisfaction score of medical auxiliaries increased from 3.83(3.33,4.5)before application to 4.50(4.33,4.83)after application,and the difference was significant(Z=2.02,P<0.05).The duration of preparing anesthesia and duration of preoperative waiting after the system was applied were respectively(62.04±2.29)and(8.09±2.46)min,both of which were less than those before the system was applied,and the differences of them between two groups were statistically significant(t=2.309,2.280,P<0.05).The usage amount of surgical gowns under same amount of surgery after the system was applied was(4.11±0.57)gowns/surgery,which was less than(5.81±0.29)gowns/surgery before the system was applied,and the difference was statistically significant(t=6.489,P<0.05).Conclusion:The application of the management system of IoT smart operation room based on business process reconstruction theory can provide more safely,high-qualitatively and efficiently medical services for patients,and improve work efficiency and management effectiveness for operation room,and reduce resource consumption and operating cost.

Objective:To investigate the clinical efficacy of botulinum toxin type A（BTX-A）bladder injection in the treatment of neurogenic detrusor overactivity（NDO）with autonomic dysreflexia（AD）.Methods:The patients with spinal cord injury at or above T6，who were treated at Guangdong Provincial Work Injury Rehabilitation Hospital from January 2018 to December 2022，were included in this study prospectively. Inclusion criteria：①chronic spinal cord injury patients over 18 years old（with no progression of neurological symptoms within 3 months）；② presence of NDO and AD；③ inadequate response or intolerance to oral antimuscarinic agent（M-receptor antagonists or β 3-receptor agonists）④ perform clean intermittent catheterization to empty the bladder. Exclusion criteria：① primary disease in the acute or progressive phase；② previous surgeries that would affect lower urinary tract function，such as transurethral sphincterotomy，bladder neck resection，prostatectomy，or bladder surgery；③ allergy to BTX-A or its adjuvants，or those with allergic predisposition ④ patients who were pregnant，breastfeeding，or planning for pregnancy in the near future；⑤ patients did not accept or were unable to perform intermittent catheterization. Before treatment，all patients were required to maintain 3-5 day urine diary，along with urodynamic studies（UDS），incontinence specific quality of life instrument（I-QOL）and AD symptom severity assessment，and blood pressure monitored. Key UDS parameters recorded included maximum bladder capacity，maximum detrusor pressure during filling phase，changes in maximum systolic blood pressure（SBP）relative to baseline（ΔSBP）during UDS examination，and the frequency of 24-hour blood pressure exceeding baseline by 20 mmHg. After general anesthesia or epidural anesthesia，BTX-A（200 U）was injected into the bladder at 30 points（including the triangle）under the cystoscope using a special injection needle，6.7 U per injection，and then the catheter was kept for 3-5 days after treatment. Three months later，relevant indicators were collected and compared with pre-treatment data. Results:A total of 43 patients were included in this study，including 34 males and 9 females. The age was（39.23±13.17）years old and the disease course was（2.69±3.27）years old. There were 33 cervical and 10 thoracic cases. The American Spinal Injury Association Injury Scale score distribution was as follows：26（60%）A，4（9%）B，9（21%）C，and 4（9%）D. The presence of AD was confirmed in all patients during urodynamic examination（UDS），that was the systolic blood pressure（SBP）suddenly increased and exceeded 20 mmHg（1 mmHg = 0.133 kPa）. Before treatment，The AD symptoms severity score（consist of headache，sweating，goose bumps，anxiety and palpitation）were（14.53±2.51），Bladder-related AD frequency was 10.67 episodes/day. Baseline SBP was（103.51±9.64）mmHg，the maximum SBP was（150.40±22.75）mmHg，and the change in SBP（ΔSBP）from maximum to baseline SBP during UDS examination was（43.83±21.01）mmHg. The UDS indicated that the maximum detrusor pressure during storage phase was（54.95±24.68）cmH 2O，and the bladder capacity was（131.70±75.29）ml. Bladder diary showed the volume of catheterization each time from was（181.16±49.86）ml，and The I-QOL score was（44.07±8.60）. Three months after treatment，the AD symptoms severity score（consist of headache，sweating，goose bumps，anxiety and palpitation）were（11.37±2.39）. The frequency of bladder-related AD episodes was（7.51±2.37）episodes/day，showing statistically significant differences compared to pre-treatment（ P<0.05）.The SBP before UDS examination was（102.12±10.28）mmHg，with no statistically significant difference from baseline（ P = 0.518）. The maximum SBP in perfusion phase and the ΔSBP were（132.84±16.30）mmHg and（28.72 ± 14.02）mmHg，respectively，both demonstrating statistically significant differences（ P < 0.05）. The UDS examination revealed that the maximum detrusor pressure during the storage phase was（29.77±13.72）cmH 2O，showed a significant decrease，and the bladder capacity was（272.63±79.75）ml，which were both statistically different before and after surgery. Bladder diary showed the volume of catheterization each time was（326.74±63.71）ml；I-QOL score was（71.86±11.45），both were significant different after treatment（ P < 0.01）. Conclusion:BTX-A intravesical injection in the treatment of NDO can also alleviate the severity and frequency of bladder related AD.

Objective:To explore the causes of self-management dilemma in young and middle-aged patients with recurrent acute pancreatitis from the perspectives of nurses, patients and patient caregivers, in order to provide reference for developing self-management intervention plans that meet the needs of patients.Methods:Using the descriptive phenomenological methods from qualitative research, 15 patients with recurrent acute pancreatitis, six nurses and nine caregivers from the Hepatobiliary Pancreatic Surgery Ward of the Second Norman Bethune Hospital of Jilin University from November 2021 to December 2022 were selected for semi-structured in-depth interviews. The Colaizzi 7-step method was used to analyze and refine the theme.Results:Two main themes were extracted to explain the difficulties in self-management of young and middle-aged patients with recurrent acute pancreatitis. The internal reasons for the self-management dilemma included cognitive biases in the importance of self-management, limited access to self-management knowledge and negative attitudes towards self-behavior management, and the external reasons for self-management dilemma included insufficient inclusiveness of the external environment towards diseases, fear of disease progression, multiple burdens caused by diseases and busy work.Conclusions:Young and middle-aged patients with recurrent acute pancreatitis experience multiple difficulties in the process of self-management. Clinical medical staff should explore self-management models with contemporary characteristics, enhance patient self-management ability and quality of life, reduce disease recurrence rate.

Objective To detect the expression of p-ERK5 and WT-1 in cancer tissues of the patients with high-grade serous ovarian cancer(HSOC),and to analyze their relationship with the prognosis of the pa-tients to provide a basis for judging the prognosis of HSOC patients.Methods Fifty-four patients with HSOC visiting in the gynecology and obstetrics department of the Affiliated Hospital of North China University of Technology from January 2008 to December 2019 were selected as the study subjects.The age,clinical stage,lymph node metastasis,complicating ascites,recurrence within 3 years,platinum sensitive,interval debulking surgery(IDS)and CA125 level at first visit were collected.The ovarian cancer tissue samples were collected.The expression levels of p-ERK5 and WT-1 protein in ovarian cancer tissues were detected by immunohisto-chemistry.The expression situation of the two kinds of factors were compared among different clinicopatho-logical features.The Kaplan-Meier method and COX regression analysis were used to evaluate the prognosis of the patients with HSOC.Results The median progress free survival(PFS)in the p-ERK5 and WT-1 protein low-expression groups was 36.0 months and 37.0 months respectively,which in the high-expression groups was 17.0 months and 15.0 months respectively.The median overall survival(OS)in the p-ERK5 and WT-1 protein low expression group was 90.0 months,which in the high expression group was 40.0 months,and the difference was statistically significant(P＜0.001).Conclusion The high expression of p-ERK5 and WT-1 protein is associated with PFS time and OS time.

Antiviral therapy is an effective means of curing chronic hepatitis C (CHC) and a key focus of preventing the spread of hepatitis C. By analyzing domestic and foreign literature, this paper provides an overview of the estimation of the antiviral treatment rate for CHC, the current situation of antiviral treatment for CHC both domestically and internationally, and the factors that affect acceptance of antiviral treatment. At present, the antiviral treatment rate for CHC cases is relatively low both domestically and internationally. The treatment status of CHC cases is related to factors such as the general situation of the case, knowing their HCV status or self-perceived condition, concurrent presence of other diseases or conditions, knowledge of hepatitis C prevention and treatment, and social interaction and behavioral guidance. In response to the relevant difficulties, in-depth research or more support is needed to improve the antiviral treatment rate of CHC cases and achieve the goal of eliminating hepatitis C by 2030. Efforts should be made to strengthen policy support, improve the diagnosis of hepatitis C, prevent and control multiple diseases together, conduct targeted publicity and education, and enhance social support.
