Objective:To investigate the application value of cannulated screws in the treatment of Hauck type Ⅱ ulnar styloid process fracture.Methods:The clinical data of 93 patients with Hauck type Ⅱ ulnar styloid process fracture who received treatment at Fuzhou Second Hospital Affiliated to Xiamen University from December 2020 to February 2023 were retrospectively analyzed for a case-control study. Among these patients, 38 patients did not undergo surgical fixation and 55 patients underwent surgical fixation. Twenty-seven patients underwent surgical fixation with cannulated screws and twenty-eight patients underwent surgical fixation with Kirschner wires. The fracture healing, postoperative rehabilitation, and functional recovery of the wrist were compared among groups.Results:The fracture healing rate and the incidence of distal radioulnar joint instability in the surgical fixation group were 100.00% (55/55) and 5.45% (3/55), respectively. These were significantly higher and lower respectively compared with the non-surgical fixation group [57.89% (22/38), 50.00% (19/38), χ 2 = 27.66, 24.69, both P < 0.001]. The wrist function recovery in the surgical fixation group was significantly superior to that in the non-surgical fixation group ( Z = -5.18， P < 0.001). There were no statistically significant differences in operative time and intraoperative blood loss between the cannulated screw group and the Kirschner wire group [(21.41 ± 5.15) minutes vs. (20.93 ± 5.71) minutes, (2.11 ± 0.97) mL vs. (2.07 ± 0.90) mL, t = 0.32, 0.15, both P > 0.05]. The fracture healing time and rehabilitation intervention time in the cannulated screw group were shorter than those in the Kirschner wire group [(6.48 ± 1.05) weeks vs. (9.14 ± 1.24) weeks, (2.11 ± 0.32) weeks vs. (3.11 ± 0.57) weeks, t = 8.57, 7.98, both P < 0.001]. The postoperative wrist function scores in the cannulated screw group were superior to those in the Kirschner wire group ( Z = -2.21, P < 0.05). Conclusion:For patients with Hauck type Ⅱ ulnar styloid process fracture, surgical fixation can promote the recovery of wrist function after surgery, and cannulated screw fixation is an effective method for the treatment of Hauck type Ⅱ ulnar styloid process fracture.

Objective:To construct a physical restraint reduction scheme based on eCASH concept (that is early Comfort using Analgesia, minimal Sedatives and maximal Human care for adult patients after cardiac surgery, and intervene, and to evaluate its effectiveness.Methods:A non-synchronous case-control study was conducted. A total of 486 patients after cardiac surgery admitted to the cardiac surgery intensive care Unit (ICU) of Shandong Provincial Hospital Affiliated to Shandong First Medical University from July to October 2022 were enrolled as subjects. According to the implementation time node of the physical restraint reduction scheme, 250 patients admitted from July to August were served as the control group, and 236 patients admitted from September to October were served as the observation group. The control group adopted the routine physical restraint nursing process, including selecting the appropriate restraint device according to the patient's condition and consciousness and following the doctor's advice, and checking on time to prevent adverse reactions. The observation group implemented the physical restraint reduction scheme based on eCASH concept, including preoperative visit, postoperative assessment of whether patients needed physical restraint according to the restraint decision wheel and the physical restraint flow, and adopted personalized nursing programs. The restraint rate, restraint duration, incidence of restraint-related complication (edema of the limbs, redness and swelling of the skin in the restricted area, skin rupture, etc.), restraint device application standard rate, delirium rate and incidence of unplanned extubation event were compared between the two groups.Results:There was no significant difference in age, gender, cardiopulmonary bypass, endotracheal catheter retention duration and operation type between the two groups with comparability. The restraint rate in the observation group was significantly lower than that in the control group [16.95% (40/236) vs. 84.40% (211/250), P < 0.01], and the restraint duration was significantly shorter than that in the control group [hours: 0 (0, 1.0) vs. 7.0 (5.5, 10.0), P < 0.01], the incidence of restraint-related complication and delirium were significantly lower than those in the control group [restraint-related complication: 0.85% (2/236) vs. 1.60% (4/250), delirium: 0% (0/236) vs. 2.80% (7/250), both P < 0.05], and the restraint device application standard rate was significantly higher than that in the control group [100.00% (40/40) vs. 90.52% (191/211), P < 0.05]. No unplanned extubation event occurred in both groups. Conclusion:The physical restraint reduction scheme based on eCASH concept in adult patients after cardiac surgery can effectively reduce the restraint rate and the incidence of restraint-related complication, shorten the restraint duration, reduce the incidence of delirium, improve the standardization of restraint device application, without increasing the incidence of unplanned extubation events.

Objective To investigate the value of a nomogram model constructed from intratumoral and peritumoral magnetic resonance imaging radiomics combined with clinical characteristics in predicting the status of lymphovascular space invasion(LVSI)in cervical cancer.Methods A retrospective analysis was conducted on 178 cervical cancer patients confirmed by postoperative pathology,with 70 cases of LVSI(+)and 108 cases of LVSI(-).The patients were divided into a training set[142 cases,including 54 cases of LVSI(+)and 88 cases of LVSI(-)]and a test set[36 cases,including 16 cases of LVSI(+)and 20 cases of LVSI(-)]at a ratio of 8:2.All underwent magnetic resonance imaging before surgery,and regions of interest were manually delineated layer by layer on the T2WI sequence,with the peritumoral region being uniformly expanded outward.Univariate logistic analysis was performed on clinical factors to select independent factors for cervical cancer LVSI(+).Radiomic features were extracted separately from the intratumoral region,the peritumoral region,and the intratumoral-peritumoral region to construct radiomics models,and the differences between the peritumoral and the intratumoral-peritumoral models were compared.A combined model was established based on the radiomics scores of the optimal intratumoral-peritumoral model and clinical independent predictive factors,and a nomogram was plotted.Receiver operating characteristic curves were used to evaluate the diagnostic performance of each model,and decision curve analysis was used to assess the clinical value of the models.Results The combined model demonstrated the best performance among the various models,with AUC of 0.970 in the training set and 0.803 in the test set.Conclusion Intratumoral and peritumoral magnetic resonance imaging radiomics combined with clinical characteristics can effectively predict LVSI in cervical cancer.

Objective To explore the feasibility and diagnostic value of ultra-fast scanning scheme based on deep learning-based reconstruction(DLR)for cervical MR examination.Methods Thirty-six subjects were prospectively enrolled and underwent both conventional scheme(scan time:6 min 14 s)and ultra-fast scheme(2 min)cervical spine MR scanning to acquire encompassing sagittal T1WI,sagittal adipose suppression T2WI and axial T2WI.The ultra-fast MRI were reconstructed using DLR method.The subjective and objective evaluations on imaging qualities of different MRIs were compared,along with the inter-observer agreement for diagnosing intervertebral disc degeneration and herniation.Results Compared with conventional MRI,artifacts in ultra-fast DLR images significantly reduced(P＜0.05).The subjective evaluation results of MRI had good agreement(all Kappa≥0.60).Compared with conventional MRI,the sagittal T1WI,T2WI and axial T2WI obtained with ultra-fast DLR showed significantly improved signal-to-noise ratio(SNR)of the spinal cord,cerebrospinal fluid(CSF)and vertebral body,as well as the spinal cord/CSF contrast(all P＜0.001).The Kappa value of 2 physicians for diagnosing intervertebral disc degeneration based on ultra-fast DLR and conventional scheme images was 0.94 and 1.00,respectively,of intervertebral disc herniation was 0.96 and 0.98,respectively.Conclusion Compared with conventional scanning scheme,using ultra-fast DLR scheme in cervical MR examination could shorten scanning time while achieve similar image quality and diagnostic accuracy.

【Objective】 To explore the relationship between the storage time of leukodepleted red blood cells and transfusion adverse reactions by analyzing the occurrence of transfusion adverse reactions of patients after leukodepleted red blood cells transfusion from four hospitals. 【Methods】 By using the electronic medical record management system, the collection and transfusion dates of leukodepleted red blood cells from four hospitals in Enshi Prefecture from 2018 to 2022, as well as the information on transfusion adverse reactions, were retrieved. 【Results】 From 2018 to 2022, a total of 697 61 bags of leukodepleted red blood cells were transfused in four hospitals, resulting in 166 cases of transfusion adverse reactions, among which 93 were allergic reactions, 63 were non hemolytic febrile reactions, and 10 were others, with a total incidence rate of transfusion adverse reactions at 0.24%. The average storage time of leukodepleted red blood cells with and without transfusion adverse reactions was (20.25±6.31) and (19.88±5.50) days, respectively. With a storage time of 7 days as the threshold, the incidence of transfusion adverse reactions was the lowest for a storage time of 15~21 days. The incidence of transfusion adverse reactions of leukodepleted red blood cells in two groups (with storage days ≤21 days and >21 days) was not statistically significant(P>0.05). 【Conclusion】 Allergic reactions were the main type of transfusion adverse reaction caused by leukodepleted red blood cells, and the incidence of transfusion adverse reactions decreased and then increased with the prolongation of the storage time of leukodepleted red blood cells. There was no significant difference in the incidence of transfusion adverse reactions with leukodepleted red blood cells stored for ≤ 21 days and >21 days.

Since 2010, the incidence of severe fever with thrombocytopenia syndrome (SFTS) has been increased. Owing the progress in diagnosis and treatment, the overall mortality of SFTS in China has decreased, while the mortality in critical SFTS patients is still high. In order to provide guidance and working procedures for clinicians to diagnose and treat critical SFTS, the National Medical Center for Major Public Health Events invited experts to discuss and formulate this consensus based on their experience and up-to-date knowledge on SFTS.

Under the background of the comprehensively implementing the rule of law, the construction of legal practice of medical institutions in China is directly related to the sustainable and high-quality development of the medical service industry. However, at present, each medical institution lacked a systematic plan for the construction of legal practice, and the health administrative department mostly implemented the measures of inspection and punishment for illegal practice, which led to the situation that the illegal practice of medical institutions was " investigated but not corrected, and changed but invalid" . This paper creatively put forward the application research of administrative reconciliation theory in the legal practice management of medical and health institutions, for promoting medical and health institutions and medical staff to strengthen legal practice management, standardizing medical behavior, ensuring medical safety, and achieving high-quality development through the institutional incentive and guidance.
