Objective To investigate the effect of 3D technology combined with smartphones in problem-based learning(PBL)for neuroendoscopy.Methods 82 trainees who were enrolled from January 2021 to January 2023 were selected as the research subjects.A randomized controlled trial was conducted,and the subjects were divided into a control group and an experimental group.PBL and 3D technology combined with smartphone-assisted PBL were implemented respectively for two groups of students.The data were analyzed using t-test.Teaching satisfac-tion is evaluated by 2 test.Results The results of the in-operation examination and theoretical examination of the ex-perimental group students were found to be higher than those of the control group students(t=8.630,6.087,P＜0.001),the satisfaction scores of students and teachers showing that the satisfaction of the experimental group was higher than that of the control group(x2=4.213,6.301,7.026,P＜0.01).Conclusion In the PBL of neuroendosco-py,the use of 3D technology combined with smart phones as an auxiliary teaching system can effectively improve students'sense of participation,reduce the difficulty of skull base anatomy learning,and improve students'theo-retical and surgical assessment scores and teaching satisfaction.

Objective In the clinical teaching of neurosurgery,the traditional Problem-Based Learning(PBL)teaching model faces systematic challenges such as the disconnection between the training cycle of specialized talents and technological iteration,the limitation of practical opportunities due to hospital infections,and the inefficient allocation of teaching resources.It provides a new path for teaching reform based on the deep integration of Artificial Intelligence and PBL,but it still needs to address issues such as differences in intern participation,insufficient technical adaptability of instructors,and fragmented resource allocation.Based on these problems,a collaborative mechanism of"technology development-talent cultivation"and a multi-dimensional optimization path of"intern participation-instructor training-hospital resource input"are proposed.On this basis,through collaborative strategies such as strengthening the incentive mechanism for autonomous learning,establishing a standardized instructor training system,and building a dynamic resource allocation platform,the management of neurosurgery clinical teaching is promoted towards intelligence,personalization,and systematization.

Diseases caused by animal virus infection seriously restricts the healthy development of animal husbandry.In-depth study of the molecular mechanism of viral replication and pathogenesis will provide theoretical basis for screening vaccine and drug targets.N6-methyladenosine(m6 A)modification occurs extensively in viral and host transcriptomes and affects viral replication and pathogenicity by regulating gene expression,which acts as a novel regulator of gene expression in addition to DNA and protein modifications.Insight into the regulatory molecular mechanism of m6 A modification in virus infection is the research hotspots and frontiers.In recent years,there are re-ports of alternation of the m6 A modification-associated epitranscriptomes and related function a-nalysis during virus infection.Here,we summarize the alternation of the epitranscriptomes induced by African swine fever virus(ASFV),porcine reproductive and respiratory syndrome virus(PRRSV),porcine epidemic diarrhoea virus(PEDV),cestode virus(CSFV),porcine pseudorabies virus(PRV),Marek's disease virus(MDV),Newcastle disease virus(NDV),avian leukaemia virus(ALV)and duck hepatitis A virus(DHAV)infection,and the subsequent effects on viral replica-tion and pathogenicity.We also discuss the potential role and molecular mechanism of m6 A modification in animal virus replication and pathogenesis,which will contributes to the prevention and control for animal disease.

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.

Cholangiocarcinoma is a highly heterogeneous tumor with an insidious onset,severe conditions,a high degree of malignancy,and an extremely poor prognosis.Glucose is a major energy source for the proliferation and metastasis of cholangiocarcinoma,and the glucose metabolism pathway of cholangiocarcinoma cells will be re-edited in the process of rapid proliferation to produce a large amount of energy for their own needs.Traditional Chinese medicine has unique advantages in the treatment of cholangiocarcinoma,and studies have shown that the active components of traditional Chinese medicine can inhibit the development and progression of cholangiocarcinoma by regulating glucose metabolism.This article reviews the characteristics of glucose metabolism in cholangiocarcinoma and the role of the active components of traditional Chinese medicine in regulating glucose metabolism against cholangiocarcinoma,in order to provide new ideas for the treatment of cholangiocarcinoma.

Objective:To explore the characteristics of sleep disorders in patients with Parkinson's disease (PD) and its correlation with homocysteine.Methods:Totally 75 PD patients hospitalized in the department of neurology from January 2017 to June 2021 were selected and divided into sleep disorder group ( n=39) and non-sleep disorder group ( n=36)according to polysomnography, Parkinson's disease sleep scale(PDSS) and Epworth sleepiness scale(ESS). The basic clinical data, hematological examination results, scale evaluation data and polysomnography monitoring data of the above patients were collected during hospitalization to analyze the sleep characteristics of patients with Parkinson's disease and its correlation with homocysteine.SPSS 26.0 statistical analysis software was used for t test, Mann-Whitney U test, Pearson analysis, Spearman analysis and multivariate Logistic analysis. Results:The sleep efficiency (56.82±19.07)%, N2 phase ratio(48.67±17.70)%, N3 phase ratio(9.20%(19.00%)) and the leg movement micro-arousal index(0(1.20)) in the sleep disorder group were lower than those in the non-sleep disorder group (sleep efficiency (82.15±5.55)%, N2 phase ratio(57.02±2.80)%, N3 phase ratio(20.01%(3.93%)), the leg movement micro-arousal index(1.15(1.80)). The differences were statistically significant ( t/ Z=-6.087, -2.905, -3.773, -3.683, all P<0.05). The proportion of AHI (0.90(14.60)), N1 stage (19.50%(15.70%)), and periodic limb index (0(24.80)) in sleep disorder group were higher than those in non-sleep disorder group (AHI (0.60(0.30)), N1 stage (12.15%(3.15%)), and periodic limb index (0(0)). The difference was statistically significant ( Z=2.154, 5.250, 3.559, all P<0.05). The homocysteine (15.80(3.90) μmol/L), NMSS-insomnia correlation score (3.00(5.00)), MDS-UPDRS-Ⅰ(7.00 (10.00)), MDS-UPDRS-Ⅲ (23.00 (16.00)) in the sleep disorder group were higher than those in the non-sleep disorder group (homocysteine (14.10 (4.20)μmol/L), NMSS-insomnia correlation score (0(1.00)), MDS-UPDRS-Ⅰ(3.00 (2.00)), MDS-UPDRS-Ⅲ (17.00 (4.00)), and the differences were statistically significant( Z=2.557, 4.487, 2.952, 2.180, all P<0.05). The NMSS-olfactory correlation scores (2.00(4.00)) and PDSS (99.00 (40.00)) were lower than those in the non-sleep disorder group (NMSS-olfactory correlation scores (4.50 (7.00)) and PDSS (122.00 (28.00)), and the differences were statistically significant ( Z=2.450, 4.126, both P<0.05). Hcy was positively correlated with sleep disorder in PD patients ( r=0.297, P<0.05). Binariate logistic regression analysis showed that elevated homocysteine level might be a risk factor for sleep disorder in PD patients ( β=0.193, OR=1.213, 95% CI=1.029-1.430). Conclusion:Parkinson's disease patients with sleep disorder have the characteristics of sleep structure disorder, often accompanied by more serious motor disorders, and the olfactory function impairment is relatively mild. Elevated homocysteine levels may be a risk factor for sleep disorder in Parkinson's disease.
