Objective:To systematically evaluate the predictive value of the reverse shock index multiplied by the Glasgow coma scale score (rSIG) for mortality of trauma patients.Methods:A comprehensive literature search was conducted to identify studies on the predictive value of rSIG for mortality of trauma patients in the following databases from inception to April 2025, including CNKI, Wanfang Data, SinoMed, PubMed, Cochrane Library, Web of Science, and Embase. Two investigators independently screened the literature, extracted data, and assessed study quality according to predefined inclusion and exclusion criteria. The Quality assessment of diagnostic accuracy studies-2 (QUADAS-2) tool was used to evaluate the risk of bias in the included studies. Meta analysis was performed using Stata 17.0 software with a bivariate mixed-effects model. The following metrics were used to assess the predictive value of rSIG for mortality in trauma patients, including sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the summary receiver operating characteristic (SROC) curve (AUC). The influence of various factors on the predictive performance of rSIG was examined, including injury type, study design, region, sample size, cut-off value, rSIG measurement time, and outcome measures. Additionally, sensitivity analysis, Fagan′s nomogram, and Deeks′ funnel plot were employed to assess the robustness of the findings, clinical applicability, and publication bias.Results:A total of 15 studies involving 710 612 trauma patients were included, 26 105 of whom were deceased. Meta analysis results showed that rSIG had a pooled sensitivity of 0.78(95% CI 0.71, 0.84), a pooled specificity of 0.78(95% CI 0.68, 0.86), a pooled PLR of 3.60(95% CI 2.46, 5.27), a pooled NLR of 0.28(95% CI 0.22, 0.36), a pooled DOR of 12.70(95% CI 8.10, 19.91), and an AUC of 0.85(95% CI 0.81, 0.87) for predicting mortality of trauma patients. Subgroup analysis identified injury type as one of the major sources of heterogeneity, and the predictive specificity of rSIG was significantly higher in patients with multiple trauma (0.82) than in those with isolated traumatic brain injury (0.65) ( P<0.05). Sensitivity analysis indicated that the findings were robust and stable. Fagan′s nomogram showed that when the pre-test probability was 7%, the post-test probability of death increased to 21% in patients with low rSIG and decreased to 2% in those with high rSIG. Deeks′ funnel plots suggested no significant publication bias among the included studies ( P>0.05). Conclusion:Low rSIG has good predictive performance for mortality of trauma patients and can serve as an effective tool for early and rapid prognosis assessment with superior predictive performance in patients with multiple trauma compared to those with traumatic brain injury.

[Purpose]To analyze the incidence and mortality of malignant tumors in cancer regis-tration areas of Heilongjiang Province in 2019 and the trend from 2013 to 2019.[Methods]The incidence and mortality data of malignant tumors reported by the Heilongjiang provincial cancer registries from 2013 to 2019 were collected,and the quality of data was assessed.The crude in-cidence/mortality rate,age-standardized incidence/mortality rate by Chinese standard population(ASIRC/ASMRC)and world standard population(ASIRW/ASMRW),0～74 years old cumulative rate were calculated.Joinpoint 4.6.0 software was used to calculate the average annual percentage change(AAPC)of ASIRC/ASMRC for the trend analysis from 2013 to 2019.[Results]In 2019,there were 16 732 new cases of malignant tumors in the cancer registration areas of Heilongjiang Province,including 8 639 males and 8 093 females.The crude incidence rate was 295.37/105,with an ASIRC and ASIRW of 167.10/105 and 164.18/105,respectively.There were 10 988 malig-nant tumor deaths,including 6 540 males and 4 448 females.The crude mortality rate was 193.97/105,with an ASMRC and ASMRW of 101.22/105 and 101.66/105,respectively.The inci-dence and mortality of malignant tumors increased rapidly after the age of 55,and the incidence and mortality of males were slightly higher than those of females.The top five malignant tumors of high incidence were lung cancer,female breast cancer,colorectal cancer,liver cancer and thy-roid cancer,and the top five malignant tumors of high mortality were lung cancer,liver cancer,colorectal cancer,stomach cancer and female breast cancer.From 2013 to 2019,the ASIRC of malignant tumors in cancer registration areas increased from 153.08/105 in 2013 to 167.10/105 in 2019,and the ASMRC increased from 92.22/105 in 2013 to 101.22/105 in 2019,but there was no statistical difference in the change trend.[Conclusion]The incidence and mortality of malignant tumors in Heilongjiang Province remain high.Lung cancer,female breast cancer,colorectal can-cer,liver cancer and stomach cancer should be the focus of cancer prevention and control.

Objective:To clarify the definition and attributes of change fatigue among nurses.Methods:A comprehensive literature search was conducted across both Chinese and international databases, including CINAHL, Cochrane Library, Web of Science, PubMed, ProQuest, ScienceDirect, Springer Link, Wanfang Data, China National Knowledge Infrastructure, VIP, and China Biology Medicine disc, from inception to December 2024. Walker and Avant's classic concept analysis method was adopted.Results:A total of 30 relevant studies were included. The defining attributes of nurse change fatigue include perception of change, negative psychological responses, and passive reactions. Antecedents involve personal and organizational factors, and the consequences affect nurses themselves, patients, and the organization.Conclusions:Concept analysis helps clarify the connotation of nurse change fatigue, enabling managers to identify its features and providing a foundation for future targeted interventions to mitigate fatigue and promote nurses' positive responses to organizational change.

Objective:To evaluate value of CT perfusion in evaluating the efficacy of different vascular reconstruction methods in the treatment of adult ischemic moyamoya disease.Methods:The clinical data of 80 adult patients with moyamoya disease with ischemic blood type who received revascularization in the Affiliated Hospital of Jining Medical University from February 2019 to February 2023 were retrospectively analyzed, including 43 patients who received superficial temporal arterio-middle cerebral artery anastomosis (direct group) and 37 patients who received brain-dural arterio-artery vascularization (indirect group). The improvement of clinical symptoms, Modified Rankin Scale (mRS) Score, collateral vessels and CTP parameters were compared between the two groups.Results:The improvement of clinical symptoms in the direct group was better than that in the indirect group ( P<0.05), and the significant remission rate was significantly higher than that in the indirect group [86.0%(37/43) vs 59.5%(22/37), χ 2=7.262, P=0.007]. The postoperative mRS score in the direct group was significantly lower than that before surgery [0(0, 1) vs 1(1, 2), Z=5.550, P<0.001]. The score of mRS After surgery in the indirect group was significantly lower than that before surgery [0(0, 1) vs 1(1, 2), Z=4.281, P<0.001], but there was no statistically significant difference between the two groups ( P>0.05). There was no significant difference in digital subtraction angiography (DSA) collateral vessel formation between the two groups ( P>0.05). The CTP parameters of the two groups before and after surgery were consistent between observers and within observers [intraclass correlation coefficient (ICC) range 0.88-0.94]. In the operation area, the relative cerebral blood flow (rCBF) after surgery was significantly increased, and the relative time to peak (rTTP) and relative mean transit time (rMTT) were significantly decreased in both groups, with statistical significance ( P<0.05). In the ipsilateral basal ganglia and frontal lobe, rCBF in the direct group was significantly increased, rTTP and rMTT were significantly decreased, and the differences were statistically significant (all P<0.05), while there were no statistically significant differences in parameters in the indirect group (all P>0.05). The changes of rCBF, rTTP and rMTT in the operative area in the direct group were better than those in the indirect group, and the changes of rCBF, rTTP and rCBF in the basal ganglia and frontal lobe were better than those in the indirect group, with statistical significance (all P<0.05), while there were no statistically significant differences in the remaining parameters (all P>0.05). Conclusions:CT perfusion is of great value in evaluating the difference of clinical symptom improvement in the treatment of adult ischemic moyamoya disease with different vascular reconstruction methods.

Clinically,tandem carotid artery stenosis(TCAS)is a relatively rare atherosclerotic disease,and with the development of interventional techniques,its treatment has become more and more minimally invasive,and the technical feasibility of hybrid surgery(HS)has been already confirmed for long time.In recent years,with the increasing of the number of patients and the deepening of research both at home and abroad,it has been found that the safety and effectiveness of HS for TCAS are still questionable,and it is particularly important to choose the appropriate treatment for such patients.This article aims to make a comprehensive review about the HS for TCAS,focusing on its surgical process,comparison of its surgical methods,and the current controversies over the treatment of TCAS,with the hope that clinicians can get a more comprehensive understanding about this surgical method.(J Intervent Radiol,2024,32:95-99)

Objective:To understand the current status of human resources in Operating Room nursing in China, so as to provide reference for nursing management, human resource allocation, nursing education and training in Operating Rooms.Methods:Using the stratified sampling method, a self-made Operating Room nursing human resource survey questionnaire of Chinese Nursing Society was used as a research tool in July 2021 to investigate the general situation, surgical workload, human resource allocation, Operating Room management, Operating Room information construction, nursing education and training of 2 201 hospitals in 31 provinces, autonomous regions and municipalities of China.Results:Among the 2 201 hospitals, there were 1 021 tertiary hospitals (46.39%), 1 177 secondary hospitals (50.75%), and 63 primary and below hospitals (2.86%). There were 2 056 hospitals with less than 30 Operating Rooms, accounting for 93.41%. There were 1 991 hospitals with an annual number of surgical cases less than 20 000, accounting for 90.46%, the educational background of Operating Room nurses was mainly undergraduate (66.93%, 43 359/64 780), with a total of 67.99% (44 045/64 780) having a bachelor's degree or above. Nurses were the main professional titles (42.66%, 27 632/64 780). Number of Operating Rooms: the number of Operating Room nurses (median) was 1: 2.43 and 78.96% (1 738/2 201) of hospital operating theatres were managed by Nursing Departments or hospitals. A total of 1 479 hospitals (67.20%) established anesthesia recovery rooms in their Operating Rooms, which was higher than 59.34% (1 210 hospitals) surveyed in 2016, and the difference was statistically significant (χ 2=226.701, P<0.01). 74.69% (1 644/2 201) and 87.87% (1 934/2 201) of hospitals carried out post management and capacity classification management in Operating Rooms, respectively. Day surgery and robotic surgery were performed in 47.80% (1 052/201) and 7.68% (169/2 201) hospitals, respectively. 36.98% (814/2 201) of the hospitals passed the information evaluation system certification and 64.61% (1 422/2 201) of the hospitals used the Operating Room information management system. In the Operating Room information system of the hospital, 2.54% (56/2 201) had intelligent functions. And 77.24% (1 700/2 201) of hospitals participated in the qualification training of Operating Room specialist nurses. Conclusions:By July 2021, the number of Operating Rooms in most hospitals in China is less than 30, and the annual number of operating cases is less than 20 000. The educational background and professional title of Operating Room nurses are mainly undergraduate and nurse. More than 60% of hospitals have set up anesthesia recovery rooms and have information management systems for Operating Rooms. At the same time, Operating Rooms in Chinese hospitals have widely implemented diversified nursing management models such as post management and ability grading management.
