Objective To explore the clinical characteristics and prognostic analysis of acute corpus callosum in-farction.Methods A total of 1 466 patients with acute cerebral infarction admitted to the Neurology Department of Jiangbin Hospital in Guangxi from January 2019 to October 2023 and Neurology Department of Fuwai Hospital,Chinese Academy of Medical Sciences from January 2022 to December 2022.Among them,21 patients with acute corpus callosum infarction confirmed by MRI(observation group)and 25 patients with isolated subcortical infarction at the same period(control group)were selected.By comparing clinical data and follow-up information between two groups,we summarized the clinical characteristics of acute corpus callosum infarction,and analyzed the relevant factors affecting the prognosis of the corpus callosum infarction group.Results Acute corpus callosum infarction accounted for 1.43％(21/1 466)of patients with acute cerebral infarction in the same period.The main clinical manifestations include limb paralysis,cognitive decline,and speech impairment.Compared with the control group,the group with corpus callosum infarction had a longer onset visit time(P<0.05),more cognitive impair-ment(P<0.05),a higher proportion of mild stroke(P<0.05),more worsening symptoms during the course of the disease(P<0.05),a higher proportion of cardioembolic type(P<0.05),a lower proportion of small artery occlu?sion type(P<0.05)and a higher proportion of good prognosis(mRS score≤2 points)(P<0.05).The poor prog?nosis of corpus callosum infarction was found to be related to factors such as large lesions,multiple high?risk factors(≥3),concomitant lobar infarction and worsening of symptoms during the course of the disease.Conclusions Acute corpus callosum infarction often leads to cognitive impairment and mild limb paralysis,which frequently de?lays treatment.The poor prognosis is mainly related to factors such as lobar infarction,major lesions,and worsening of symptoms during the process.

Objective To explore the effect of visual balance training combined with digital treadmill intervention on walking func-tion in patients with ischemic stroke.Methods From July,2023 to December,2024,90 patients with ischemic stroke in Gansu Provincial Hospital were ran-domly divided into control group(n=30),treadmill group(n=30)and combined group(n=30).All groups re-ceived routine rehabilitation treatment,while the treadmill group added digital treadmill training,and the com-bined group added visual feedback balance training and digital treadmill training,for four weeks.All groups were assessed with Berg Balance Scale(BBS),Pro-Kin visual feedback balance training system,Tinetti Performance-Oriented Mobility Assessment(POMA),digital treadmill system,Timed Up and Go Test(TUGT),Fugl-Meyer Assessment-Lower Extremities(FMA-LE),Functional Ambulation Category(FAC)and modified Barthel Index(MBI)before and after intervention.Results The effects of intra-group(F>147.291,P<0.001),inter-group(F>4.919,P<0.05)and interaction(F>18.386,P<0.001)were all significant for the indicators including BBS score,length trajectory and elliptical area of eyes open or closed,POMA score,step length,hip and knee range of motion on the healthy and affected side,TUGT time,FMA-LE score,and MBI score.Post-hoc tests showed that after treatment,all the above indicators improved in each group(P<0.01),and they were the best in the combined group,followed by the treadmill group(P<0.05).After treatment,the FAC grades improved in all the groups(|Z|>1.971,P<0.05),and it was better in the combined group than in the control group(P<0.01).Conclusion Visual feedback balance training combined with digital treadmill intervention can improve balance function,walking ability and activities of daily living in patients with ischemic stroke,which is more effective than tread-mill training alone.

BACKGROUND: Corneal confocal microscopy (CCM) is a noninvasive technique to detect early nerve damage of diabetic sensorimotor polyneuropathy (DSPN). Time in range (TIR) is an emerging metric of glycemic control which was reported to be associated with diabetic complications. We sought to explore the relationship between TIR and corneal nerve parameters in asymptomatic patients with type 2 diabetes (T2DM). METHODS: In this cross-sectional study, 206 asymptomatic inpatients with T2DM were recruited. After 7 days of continuous glucose monitoring, the TIR was calculated as the percentage of time in the glucose range of 3.9 to 10.0 mmol/L. CCM was performed to determine corneal nerve fiber density, corneal nerve branch density, and corneal nerve fiber length (CNFL). Abnormal CNFL was defined as ≤15.30 mm/mm 2 . RESULTS: Abnormal CNFL was found in 30.6% (63/206) of asymptomatic subjects. Linear regression analyses revealed that TIR was positively correlated with CCM parameters both in the crude and adjusted models (all P   <  0.05). Each 10% increase in TIR was associated with a 28.2% (95% CI: 0.595-0.866, P  = 0.001) decreased risk of abnormal CNFL after adjusting for covariates. With the increase of TIR quartiles, corneal nerve fiber parameters increased significantly (all P for trend <0.01). The receiver operating characteristic curve indicated that the optimal cutoff point of TIR was 77.5% for predicting abnormal CNFL in asymptomatic patients. CONCLUSIONS There is a significant independent correlation between TIR and corneal nerve fiber loss in asymptomatic T2DM patients. TIR may be a useful surrogate marker for early diagnosis of DSPN.

Objective To evaluate the clinical outcomes of hemodialysis patients after superficial femoral artery - superficial femoral vein arteriovenous graft (AVG). Methods Hemodialysis patients with mid - thigh superficial femoral artery - superficial femoral vein AVG from August 2015 to March 2018 in department of vascular surgery, Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine were enrolled. Their clinical outcomes and complications after operation were analyzed retrospectively. Patency rates were measured by Kaplan - Meier survival curve. Results A total of 18 cases were enrolled. The success rate of the operation was 100％without complication. Follow - up time was (22.00 ± 11.77) months with 100％ follow - up rate. The 6 months -, 12 months -, 24 months - primary patency rates were 83.3％±8.8％, 48.5％±12.1％, 24.2％± 13.5％, respectively; secondly patency rates were 100.0％, 100.0％, 87.5％±11.7％. There were 1 case of seroma, 1 case of puncture site infection, 11 cases of stenosis and 5 cases thrombosis during follow-up, while no heart failure, ischemia or pseudoaneurysm. Conclusion Mid - thigh AVG has low infection rate and high patency rate, so it can be as the first choice for the lower extremity AVG in hemodialysis patients.

Objective? To explore the status quo of creative self-efficacy and research performance in nursing undergraduates and to analyze the correlation between the two. Methods? Totally 190 senior nursing undergraduates who practiced in the Second Affiliated Hospital of Kunming Medical University were selected by convenient sampling and investigated with the Creative Self-Efficacy Scale and the Research Performance Self-Rating Scale for nursing staff. Results? The 190 nursing undergraduates' creative self-efficacy score totaled (65.31±9.51), and their total research performance score was (72.85±13.97). Univariate analysis revealed that there was statistically significant difference in creative self-efficacy scores between nursing undergraduates who were student leaders or not (P＜0.05); and there were statistically significant differences in research performance scores between nursing undergraduates with different English levels, computer skills and home address (P＜0.05). The scores of various dimensions creative self-efficacy were positively correlated with the scores of various dimensions of research performance (P＜ 0.01). Conclusions? Nursing undergraduates＇ creative self-efficacy and research performance need to be improved. Universities and colleges should actively launch activities which are beneficial to their research literacy and creative awareness and take scientific research activities as one of the most pathways to develop nursing students＇ research literacy and creativeness and entrepreneurship.

Objective To study the efficacy and safety of CO2 laser microsurgery for early glottis carcinoma.Methods The data of 96 cases of early glottic laryngeal carcinoma treated with CO2 laser microsurgery were retrospectively analyzed.Surgical specimens were conventionally embedded with paraffin and serially sectioned.Sections were stained by using hematoxylin-eosin for pathologic examination.The local control rate was observed after operation.Results Among the 96 specimens,88 surgical margins were negative and 8 were positive.10 patients (10.4 ％) recurrenced followed up for 3 years.The recurrence rates of Tis,T1a,T1b and T2 were 0 (0/10),4.1％ (2/48),25.0 ％ (4/16) and 18.1％ (4/22),respectively,with significant differences among groups (X2 =6.105,P ＜ 0.05).All of 8 cases with positive margin and 2 cases with negative margin were recurrened.The recurrent rate of patients with involvement of the anterior commissure was 30.0 ％ (6/20),which was higher than that of patients with no tumor invasion [5.3 ％ (4/76)] (X2 =9.624,P ＜ 0.01).Conclusions The safe edges can be obtained by CO2 laser microsurgery for early stage of glottis carcinoma,which have advantages in local control rate,vocal function of the larynx and curative effect.
