Objective To investigate whether successful percutaneous coronary intervention(PCI)could improve symptoms and quality of life(QOL)in left main disease and/or 3-vessel disease patients with diabetes.Methods Patients with left main disease and/or 3-vessel disease who underwent PCI in the First Affiliated Hospital of Air Force Medical University from April 2018 to May 2021 were consecutively enrolled and subdivided into 2 groups:diabetes and no diabetes.Detailed baseline characteristics,symptoms,including dyspnea and angina,assessed with the Rose dyspnea scale(RDS),Seattle angina questionnaire(SAQ),the European quality of life-5 dimensions(EQ-5D)and 12-item short-form health survey(SF-12)questionnaire respectively,procedural details,and 1 month and 1 year follow-up data were collected.Results Among 440 left main disease and/or 3-vessel disease patients,disease was present in 176(40.00％),who had more hypertension,peripheral artery disease,and LCX lesion(all P＜0.05).The incidence of major adverse cardiovascular events(MACE)and all-cause mortality were similar between the two groups(both P＞0.05)at 1 month follow-up,while all-cause mortality in diabetes patients was significantly higher than those without diabetes at 1 year follow-up(P=0.013).Low left ventricular ejection fraction was an independent risk factor for MACE and all-cause mortality at 1 month and 1 year follow-up after successful revascularization(all P＜0.05).Most importantly,symptoms,including dyspnea and angina,and QOL were markedly improved regardless of diabetes both at 1 month and 1 year follow-up(all P＜0.05).Diabetes patients showed improved dyspnea and QOL at similar degree to the non-diabetes patients(all P＞0.05)and a more significantly relieved angina(P=0.013).Additionally,the number of chronic total occlusion(CTO)per patient was identified as an independent risk factor of dyspnea(OR 0.723,95％CI 0.525～0.997,P=0.048)and angina relief(OR 0.686,95％CI 0.473～0.995,P=0.047),and the contrast volume(OR 0.995,95％CI 0.992～0.999,P=0.008)as an independent risk factor of QOL improvement in diabetic patients.Conclusions Successful PCI is beneficial for relieving symptoms and improving quality of life in patients with diabetes who have left main disease and/or 3-vessel disease.

Objective To observe the effect of preoperative exercise on consciousness,lung function and recovery efficiency of patients undergoing ventriculoperitoneal shunt.Methods A total of 54 patients undergoing elective ventriculoperitoneal shunt in Beijing Bo'ai Hospital from October,2024 to March,2025 were randomly divided into control group(n=27)and prerehabilitation group(n=27).The control group received routine preoperative treatment and nursing,while the prerehabilitation group additionally received exercise for two weeks.They were assessed with Coma Recovery Scale-Revised(CRS-R),and observed diaphragm mobility with sonography,before and three days after operation;and the time to first ambulation after surgery and length of stay in hospital were compared between two groups.Results CRS-R scores improved in both groups after operation(|t|>5.451,P<0.001),and it was greater in the prehabilitation group than in the control group(t=2.812,P<0.01).CRS-R subscale scores improved in auditory and motor functions in the control group(|Z|>2.000,P<0.05),and they were improved in auditory,visual,motor,verbal and arousal functions in the prehabilitation group(|Z|>2.282,P<0.01).CRS-R subscale scores were greater in motor and arousal in the prehabilitation group than in the control group(|Z|>2.320,P<0.05).Diaphragmatic mobility improved in the prehabilitation group(t=-7.782,P<0.001),and it was better than in the control group(t=2.044,P<0.05).The time to first ambulation after surgery and length of stay in hospital were shorter in the prehabilitation group than in the control group(|t|>3.654,P<0.01).Conclusion Preoperative exercise for patients undergoing elective ventriculoperitoneal shunt can improve the consciousness after operation,especially the level of motor and arousal,as well as the lung function,and accelerate the recovery process.

Objective To explore the visualization effect of different walking fibers and anatomical positions of the basal nucleus in the postcentral gyrus based on the diffusion tensor imaging(DTI)fiber bundle of the precentral gyrus and internal capsule reconstruction model.Methods A set of diffusion tensor volume(DTV)data was used to visualize and export a mesh model by a 3DSlicense 5.6.2 software.The basal nucleus were reconstructed by 3DSlicense through T1W1 data from the same scan,and exported the mesh model,and thus imported the above model into DTIANALYSIS 1.51 software for visualization.By adjusting the RGB component threshold,the fiber bundles were screened to obtain fiber bundles that mainly run left and right,front and back,and up and down.The anatomical relationship between the fiber bundles and the basal nucleus was observed.Results The fiber bundles originating from the precentral gyrus were mainly distributed in the inner and lower parts,and run above and outside the basal nucleus;The fiber bundles that mainly run forward and backward are distributed on the outer side and run on the outer side of the basal nucleus;The fiber bundles that mainly run up and down were distributed in the upper and middle parts of the precentral gyrus,with some fibers running towards the hypothalamus.They intersect in the corpus callosum and ventral pons,and run along the posterior part of the space between the lentiform nucleus and the dorsal thalamus.Conclusion Based on the RGB components in DTI,fibers with different walking directions in the precentral gyrus can be screened to display their anatomical position relationship with the basal ganglia.

PURPOSE: This study aims to identify the prevalence and risk factors of military training-related abdominal injuries and help plan and conduct training properly. METHODS: This questionnaire survey study was conducted from October 2021 to May 2022 among military personnel from 6 military units and 8 military medical centers and participants' medical records were consulted to identify the training-related abdominal injuries. All the military personnel who ever participated in military training were included. Those who refused to participate in this study or provided an incomplete questionnaire were excluded. The questionnaire collected demographic information, type of abdominal injury, frequency, training subjects, triggers, treatment, and training disturbance. Chi-square test and t-test were used to compare baseline information. Univariate and multivariate regression analyses were used to explore the risk factors associated with military training-related abdominal injuries. RESULTS: A total of 3058 participants were involved in this study, among which 1797 (58.8%) had suffered training-related abdominal injuries (the mean age was 24.3 years and the service time was 5.6 years), while 1261 (41.2%) had no training-related abdominal injuries (the mean age was 23.1 years and the service time was 4.3 years). There were 546 injured patients (30.4%) suspended the training and 84 (4.6%) needed to be referred to higher-level hospitals. The most common triggers included inadequate warm-up, fatigue, and intense training. The training subjects with the most abdominal injuries were long-distance running (589, 32.8%). Civil servants had the highest rate of abdominal trauma (17.1%). Age ≥ 25 years, military service ≥ 3 years, poor sleep status, and previous abdominal history were independent risk factors for training-related abdominal injury. CONCLUSION More than half of the military personnel have suffered military training-related abdominal injuries. Inadequate warm-up, fatigue, and high training intensity are the most common inducing factors. Scientific and proper training should be conducted according to the factors causing abdominal injuries.

Objective:To establish a graded method to avoid mean fluorescence intensity(MFI)threshold of HLA Class I antibodies corresponding antigen,and the HLAMatchmaker program has been used to select the minimum mismatch value of donor-patient epitopes.Evaluate the application value of combining both methods in selecting HLA compatible platelets(PTL)for patients with immune platelet transfusion failure(IPTR)in improving platelet the corrected count increment(CCI).Methods:A total 7 807 PLT cross-matching compatible were performed by the solid-phase red cell adherence(SPRCA)method for 51 IPTR patients.The Luminex single antigen flow cytometry was used to detect HLA Class I antibodies in patients,and detected the MFI value for different specificity antigens of HLA Class I antibodies,was graded into strong positive group(MFI＞4 000,level 1),medium positive group(1 000＜MFI 4 000,2),weak positive group(500＜MFI≤1 000,3),and one negative control group(MFI≤500).The results of 7 807 SPRCA their negative/positive reaction wells were enrolled and statistically analyzed in different grades and the four groups,the statistical differences between the four groups were compared.Multiple applications for the select HLA Class I compatible donor events were made for patients in two cases,and HLAMatchmaker program was used to calculate the number of HLA Class I epitopes mismatches between the donors and patients.The donor with the minimum number of epitopes mismatches was selected,while avoiding the corresponding antigens of HLA Class I antibodies in levels 1 and 2,the provision of HLA compatible platelets for IPTR.After the transfusions,the CCI value of the platelet transfusion efficacy evaluation index was calculated,and the clinical evaluation of the transfusion effect was obtained through statistical analysis.Results:There were statistically significant differences in the positive results of SPRCA immunoassay among the strong positive group,medium positive group,and weak positive group of 51 IPTR patients with different specific of HLA-I class antibodies and corresponding antigens(all P＜0.001).The positive results showed a range from high to low,with strong positive group＞medium positive group＞weak positive group.There were a statistical difference among between the strongly positive or moderately positive groups and the negative control group(P＜0.001).There was no statistical difference between the weakly positive group and the negative control group(P＞0.05).The strong positive group was set as the corresponding specific HLA Class I site corresponding antigen grade 1 avoidance threshold,the medium positive group as the grade 2 avoidance thresholds,and the weak positive group as the grade 3 avoidance threshold.In the case of donor platelet shortage,it is not necessary to avoid the weak positive group.Avoiding the strategy of donor antigens and HLAMatchmaker program scores≤7 corresponding to HLA Class I antibodies of levels 1 and 2,with CCI values＞4.5 × 109/L within 24 hours,can obtain effective clinical platelet transfusion conclusions.Conclusion:When selecting HLA Class I compatible donors for IPTR patients,the grading avoids HLA Class I antibodies corresponding to donor antigens,and the donor selection strategy with the minimum scores of HLAMatchmaker program is comprehensively selected.The negative result confirmed by platelet cross-matching experiments has certain practical application value for improving platelet count in IPTR patients.

Objective We aimed to compare the efficacy and prognosis of percutaneous coronary intervention(PCI)in complex and high-risk patients with coronary heart disease(CHD)treated with extracorporeal membrane oxygenation(ECMO)combined with intra-aortic balloon pump(IABP)assistance,and explore the application value of combined use of mechanical circulatory support(MCS)devices in complex PCI.Methods A total of patients who met the inclusion criteria and underwent selective PCI supported by MCS at the Department of Cardiology,the First Affiliated Hospital of the Air Force Medical University from January 2018 to December 2022 were continuously enrolled.According to the mechanical circulatory support method,the patients were divided into ECMO+IABP group and IABP group.Clinical characteristics,angiographic features,in-hospital outcomes,and complications were collected.The intra-hospital outcomes and major adverse cardiovascular events(MACE)at one month and one year after the procedure were observed.The differences and independent risk factors between the two groups in the above indicators were analyzed.Results A total of 218 patients undergoing elective PCI were included,of which 66 patients were in the ECMO+IABP group and 152 patients were in the IABP group.The baseline characteristics of the two groups of patients were generally comparable,but the ECMO+IABP group had more complex lesion characteristics.The proportion of patients with atrial fibrillation(6.1％vs.0.7％,P=0.030),left main disease(43.9％vs.27.0％,P=0.018),triple vessel disease(90.9％vs.75.5％,P=0.009),and RCA chronic total occlusion disease(60.6％vs.35.5％,P＜0.001)was higher in the ECMO+IABP group compared to the IABP group.The proportion of patients with previous PCI history was higher in the IABP group(32.9％vs.16.7％,P=0.014).There was no statistically significant difference in the incidence of in-hospital complications between the two groups(P=0.176),but the incidence of hypotension after PCI was higher in the ECMO+IABP group(19.7％vs.9.2％,P=0.031).The rates of 1-month MACE(4.5％vs.2.6％,P=0.435)and 1-year MACE(7.6％vs.7.9％,P=0.936)were comparable between the two groups.Multivariate analysis showed that in-hospital cardiac arrest(OR 7.17,95％CI 1.27-40.38,P=0.025)and after procedure hypotension(OR 3.60,95％CI 1.10-11.83,P=0.035)were independent risk factors for the occurrence of 1-year MACE.Conclusions Combination use of ECMO+IABP support can provide complex and high-risk coronary heart disease patients with an opportunity to achieve coronary artery revascularization through PCI,and achieve satisfactory long-term prognosis.

Background: and Purpose To evaluate whether the thrombus enhancement sign (TES) can be used to differentiate embolic large vessel occlusion (LVO) from in situ intracranial atherosclerotic stenosis (ICAS)-related LVO in the anterior circulation of patients with acute ischemic stroke (AIS). Methods: Patients with LVO in the anterior circulation who underwent both non-contrast computed tomography (CT) and CT angiography and mechanical thrombectomy were retrospectively enrolled. Both embolic LVO (embo-LVO) and in situ ICAS-related LVO (ICAS-LVO) were confirmed by two neurointerventional radiologists after reviewing the medical and imaging data. TES was assessed to predict embo-LVO or ICAS-LVO. The associations between occlusion type and TES, along with clinical and interventional parameters, were investigated using logistic regression analysis and a receiver operating characteristic curve. Results: A total of 288 patients with AIS were included and divided into an embo-LVO group (n=235) and an ICAS-LVO group (n=53). TES was identified in 205 (71.2%) patients and was more frequently observed in those with embo-LVO, with a sensitivity of 83.8%, specificity of 84.9%, and area under the curve (AUC) of 0.844. Multivariate analysis showed that TES (odds ratio [OR], 22.2; 95% confidence interval [CI], 9.4–53.8; P<0.001) and atrial fibrillation (OR, 6.6; 95% CI, 2.8–15.8; P<0.001) were independent predictors of embolic occlusion. A predictive model that included both TES and atrial fibrillation yielded a higher diagnostic ability for embo-LVO, with an AUC of 0.899. Conclusion TES is an imaging marker with high predictive value for identifying embo- and ICAS-LVO in AIS and provides guidance for endovascular reperfusion therapy.

Objective:To explore the diagnostic value of fine needle aspiration cytological biopsy(FNAB)under ultrasound-guided combined with the detection of point mutation of mutant B1 gene of carcinogenic homologue of murine sarcomatous virulent bacteria V600E for grade 4 nodule of thyroid imaging reporting and data system(TI-RADS)of thyroid.Methods:A total of 78 patients with TI-RADS grade 4 nodules who underwent surgery in General Hospital of Huainan Oriental Hospital Group during September 2019 and September 2021 were observed.All patients underwent ultrasound-guided FNAB examination and BRAF V600E gene testing before surgery.The postoperatively pathological results were used as gold standard to analyze the values of ultrasound-guided FNAB examination,BRAF V600E gene testing and the combined diagnosis of them.Results:Postoperatively pathological results showed 60 cases(76.92%)were malignant tumors,and all of which were papillary thyroid carcinoma.The results of Kappa consistency test between ultrasound-guided FNAB examination and pathological control,and between BRAF V600E gene testing and pathological control indicated that the Kappa values of them were respectively 0.430 and 0.583,and the Kappa value of the combined examination of them was 0.720.The sensitivity,specificity,positive predictive value and negative predictive value of the combined examination were respectively 98.33%,66.67%,90.77%and 92.31%in diagnosing thyroid nodule.Conclusion:For TI-RADS grade 4 thyroid nodule,the ultrasound-guided FNAB examination combined with BRAF V600E gene testing can significantly improve the diagnostic value.
