BackgroundIn Sichuan Province， most healthcare institutions providing mental health services have adopted self-developed evaluation indicators for the quality of nursing care in psychiatric closed wards， lacking unified standards. This results in insufficient authority and homogeneity， which is unfavorable for the standardized assessment and continuous improvement of nursing quality. ObjectiveTo construct a standardized evaluation indicator system for nursing quality of psychiatric closed wards in Sichuan Province， so as to provide references for nursing quality management and assessment. MethodsBased on bio-psycho-social medical model and guided by "Structure-Process-Outcome" quality evaluation framework， preliminary evaluation indicators for nursing quality in psychiatric closed wards were developed through literature analysis， research team discussions and clinical experience. Through two rounds of Delphi expert consultation， the indicators were revised and finalized. ResultsThe response rates for two rounds of Delphi expert consultation questionnaire were 100%. The expert authority coefficients were 0.845 and 0.864， respectively， and the Kendall's coordination coefficients ranged from 0.119 to 0.210 （P<0.01）. Ultimately， a nursing quality evaluation index system for psychiatric closed wards was established， comprising 3 first-level indicators， 9 second-level indicators and 46 third-level indicators. ConclusionThe nursing quality evaluation indicators for psychiatric closed wards constructed based on the Delphi method can provide references for nursing quality management and evaluation in such wards. ［Funded by Research Project Fund of Sichuan Nursing Society （number， H20004）； Sichuan Hospital Association Hospital Management Research Special Fund （number， YG2323）］

BackgroundPostoperative cognitive dysfunction （POCD） is a common complication in elderly patients after surgery， and has a great impact on postoperative rehabilitation of patients. ObjectiveTo explore the effect of mindfulness-based therapy on cognitive function and sleep quality in elderly patients after surgery under local anesthesia， so as to provide references for reducing their incidence risk of POCD and improving sleep quality. MethodsThe simple random sampling method was utilized to select 78 elderly patients who underwent surgery under local anesthesia in The Third Hospital of Mianyang from March 2022 to March 2023. Participants were assigned into study group and control group， each with 39 cases. All patients were subjected to conventional treatment and nursing interventions， and study group added mindfulness-based therapy on this basis. Mini-Mental State Examination （MMSE） was administered to patients on 1 day before surgery， and on the 1^st， 3^rd and 5^th day after surgery. Pittsburgh Sleep Quality Index （PSQI） was employed on 1 day before surgery and on the 3^rd day after surgery. ResultsMMSE scores revealed a significant time effect， group effect and time×group interaction effect （F=78.251， 197.071， 371.915， P<0.05）. Analysis of simple effect denoted that study group scored higher on MMSE on the 1^st， 3^rd and 5^th day after surgery compared with control group， with statistical significance （t=-3.579， -1.764， -0.253， P<0.05）. Study group reported lower incidence rates of POCD on the 1^st， 3^rd and 5^th day after surgery compared with control group， with statistical significance （χ²=2.631， 3.471， 5.135， P<0.05）. On the 3^rd day after surgery，study group scored lower on PSQI than control group（P<0.05）， and PSQI total score， sleep latency， subjective sleep quality， daytime dysfunction and hypnotic drug use factor scores of study group were lower than baseline， with statistical significance（F=43.175， 12.594， 11.092， 4.579， 3.514， P<0.01）. ConclusionMindfulness-based therapy may have certain value in reducing incidence of POCD and improving sleep quality in elderly patients who underwent surgery under local anesthesia.

Objective: The anterior controllable antedisplacement and fusion (ACAF) technique is a new procedure for the treatment of cervical ossification of the posterior longitudinal ligament (OPLL) that requires management of the disc adjacent to the ossification. This study describes a novel technique to reduce the number of fixed segments, namely, the “Klotski technique.” The efficacy of ACAF using the Klotski technique was compared with that of anterior cervical corpectomy and fusion (ACCF) in the treatment of OPLL with en bloc type dural ossification (DO). Methods: The clinical data of 25 patients with severe OPLL and en bloc type DO who were treated by the ACAF Klotski technique or ACCF at our hospital from January 2020 to January 2022 were retrospectively analyzed. In the Klotski technique, the number of segments fused within the OPLL is limited. The antedisplacement space was designed according to the shape of the vertebrae-OPLL-DO complex (VODC). Then, the entire VODC was antedisplaced as in Klotski. Neurological function and image examination were assessed preoperatively and postoperatively. Complications associated with surgery were recorded. Results: Patients were followed up for 24–36 months. There were 11 patients who were treated with ACAF and 14 patients who were treated with ACCF. At 2 weeks after surgery, the incidence of neurological deterioration was 21.4% (3 of 14) in the ACCF group and 9.1%(1 of 11) in the ACAF group. The incidence of intraoperative cerebrospinal fluid leakage (CFL) was 35.7% (5 of 14) in the ACCF group and 9.1% (1 of 11) in the ACAF group. The postoperative follow-up JOA scores of the patients in both groups were significantly better than their preoperative JOA scores (p<0.05). Conclusion The Klotski technique for ACAF is a good option for the treatment of patients with en bloc type OPLL-DO, as it limits the number of fused segments, has a low incidence of CFL and neurologic deficits and is associated with good neurological recovery.

Objective:To investigate effect of blood glucose on early neurological deterioration (END) and outcome after intravenous thrombolysis in patients with acute ischemic stroke (AIS).Methods:Patients with AIS treated with intravenous thrombolysis in the Department of Neurology, the Second Affiliated Hospital of Xuzhou Medical University from June 2020 to December 2021 were collected retrospectively. Demographic and baseline clinical data of the patients were collected. END was defined as an increase of ≥2 in reassessing the maximum score of the National Institutes of Health Stroke Scale within 72 h after admission compared with the baseline. Poor outcome was defined as the modified Rankin Scale score ≥3 at 3 months after onset. Multivariate logistic regression analysis was used to evaluate the independent correlation between various blood glucose indicators (including admission blood glucose [ABG], admission hyperglycemia [AH], fasting blood glucose [FBG] on the next day after admission, and stress hyperglycemia ratio [SHR]) and END and poor outcome after intravenous thrombolysis. Results:A total of 319 patients with AIS were enrolled, including 126 (39.5%) had AH, 67 (21.0%) had END, and 85 (26.6%) had poor outcomes at 3 months after onset. Multivariate logistic regression analysis showed that after adjusting for confounding factors, ABG (odds ratio [ OR] 1.188, 95% confidence interval [ CI] 1.105-1.278; P<0.001), AH ( OR 4.246, 95% CI 2.291-7.869; P<0.001), FBG ( OR 1.272, 95% CI 1.139-1.420; P<0.001), and SHR ( OR 2.559, 95% CI 1.192-5.664; P=0.016) were independently associated with END, while all blood glucose indicators were not independently associated with the poor outcomes at 3 months after onset. Conclusion:Higher blood glucose is independently associated with END after intravenous thrombolysis in patients with AIS, but not with the outcomes at 3 months after onset.

Recent advancement in natural language processing (NLP) and medical imaging empowers the wide applicability of deep learning models. These developments have increased not only data understanding, but also knowledge of state-of-the-art architectures and their real-world potentials. Medical imaging researchers have recognized the limitations of only targeting images, as well as the importance of integrating multimodal inputs into medical image analysis. The lack of comprehensive surveys of the current literature, however, impedes the progress of this domain. Existing research perspectives, as well as the architectures, tasks, datasets, and performance measures examined in the present literature, are reviewed in this work, and we also provide a brief description of possible future directions in the field, aiming to provide researchers and healthcare professionals with a detailed summary of existing academic research and to provide rational insights to facilitate future research.

ObjectiveTo investigate the current status of knowledge， attitude and practice of nurses in mental health hospitals on the prevention and control of nosocomial infections， and to analyze the influencing factors. MethodsFrom June to August 2020， 402 clinical nurses from 8 mental health hospitals in a city were enrolled using simple random sampling method， and were assessed using a self-compiled knowledge-attitude-practice questionnaire related to the nosocomial infection prevention and control， thereafter， the influencing factors were screened. ResultsThe scores of knowledge， attitude and practice dimensions in relation to the nosocomial infection prevention and control among the nurses were （8.43±1.84）， （76.01±5.70） and （57.42±3.75）， respectively. Univariate analysis showed that the knowledge dimension score demonstrated significant difference among nurses of different types of hospital， grades of hospital， professional titles， education levels， and emphasis degrees of hospital and individual on nosocomial infection （P<0.05 or 0.01）. The attitude dimension scores yielded significant difference among nurses of different types of hospital， position， grades of hospital， and emphasis degrees of hospital and individual on nosocomial infection （P<0.05 or 0.01）. The practice dimension scores manifested significant difference among nurses of different types of hospital， grades of hospital， professional titles， emphasis degrees of hospital and individual on nosocomial infection， and training frequency （P<0.05 or 0.01）. Multiple linear regression analysis showed that professional titles and individual emphasis on nosocomial infection entered the regression model of nurses' knowledge dimension of nosocomial infection prevention and control （P<0.05 or 0.01）. Individual emphasis on nosocomial infection， hospital types and position entered the regression model of attitude dimension （P<0.05 or 0.01）. Individual emphasis on nosocomial infection， hospital types， professional titles， and hospital emphasis on nosocomial infection entered the regression model of practice dimension （P<0.05 or 0.01）. ConclusionNurses in mental health hospital have a positive attitude towards nosocomial infection prevention and control， but their knowledge base needs to be strengthened.
