Background: and Purpose Limited evidence exists on the effectiveness of endovascular treatment (EVT) for acute posterior circulation tandem lesion (PCTL). This study aimed to explore the role of extracranial vertebral artery (VA) stenting in patients with PCTL stroke undergoing EVT. Methods: Individual patient data were pooled from the BASILAR (EVT for Acute Basilar Artery Occlusion Study) and PERSIST (Posterior Circulation Ischemic Stroke) registries. Patients with PCTLs who underwent EVT were included in the present cohort and divided into the stenting and nonstenting groups based on the placement of extracranial VA stents. The primary efficacy outcome was the modified Rankin Scale (mRS) scores at 90 days and 1 year. Safety outcomes included 24-hour symptomatic intracranial hemorrhage (sICH) and all-cause mortality at 90 days and 1 year post-surgery. Results: A combined dataset of 1,320 patients with posterior circulation artery occlusion, including 263 (19.9%) with tandem lesions, of whom 217 (median age, 65 years; 82.9% male) met the inclusion criteria for the analysis. The stenting group had 84 (38.7%) patients, while the non-stenting group had 133 (61.3%). After adjustment for the potential confounders, extracranial VA stenting was associated with favorable shifts in mRS scores at both 90 days (adjusted common odds ratio [OR], 2.30; 95% confidence interval [CI], 1.23–4.28; P<0.01) and 1 year (adjusted OR [aOR], 2.04; 95% CI [1.05–3.97]; P=0.04), along with lower rate of mortality at both 90 days (aOR, 0.45; 95% CI [0.21–0.93]; P=0.01) and 1 year (aOR, 0.36; 95% CI [0.16–0.79]; P=0.01), with no significant difference in sICH incidence (aOR, 0.35; 95% CI [0.06–1.98]; P=0.24). Conclusion Extracranial VA stenting during EVT may improve functional outcomes and reduce mortality in patients with PCTL strokes.

Objective:To identify species type and analyze the homology of Brucella in a family cluster infection. Methods:Two patients with brucellosis from the same family who were treated at the First People's Hospital of Lianyungang City, Jiangsu Province in May 2022 were selected as the research subjects. Brucella strains (H4LYG01 and H2LYG02) were isolated through blood culture. The isolated strains were identified for species type and homology analysis using a fully automated microbial mass spectrometry detection system. Molecular typing of the isolated strains was performed using multiple locus variable-number tandem-repeat analysis (MLVA) and multilocus sequence typing (MLST). Results:H4LYG01 and H2LYG02 were both Brucella Maltese, and the credibility scores were 9.745 and 9.627, respectively, and the homology was 100%. The MLVA results showed that the gene loci of H4LYG01 and H2LYG02 were completely identical, with the same genotype. The MLST results showed that the sequence type (ST) of H4LYG01 and H2LYG02 were both ST8 types. Conclusion:The two isolated strains of Brucella from a family with clustered infections are both Brucella Maltese and from the same source.

Objective:To investigate the associations of onset age, diabetes duration, and glycated hemoglobin (HbA1c) levels with ischemic stroke risk in type 2 diabetes patients.Methods:The participants were from Comprehensive Research on the Prevention and Control of the Diabetes in Jiangsu Province. The study used data from baseline survey from December 2013 to January 2014 and follow-up until December 31, 2021. After excluding the participants who had been diagnosed with stroke at baseline survey and those with incomplete information on onset age, diabetes duration, and HbA1c level, a total of 17 576 type 2 diabetes patients were included. Cox proportional hazard model was used to calculate the hazard ratio ( HR) and 95% CI of onset age, diabetes duration, and HbA1c level for ischemic stroke. Results:During the median follow-up time of 8.02 years, 2 622 ischemic stroke cases were registered. Multivariate Cox proportional risk regression model showed that a 5-year increase in type 2 diabetes onset age was significantly associated with a 5% decreased risk for ischemic stroke ( HR=0.95, 95% CI: 0.92-0.99). A 5-year increase in diabetes duration was associated with a 5% increased risk for ischemic stroke ( HR=1.05, 95% CI: 1.02-1.10). Higher HbA1c (per 1 standard deviation increase: HR=1.17, 95% CI: 1.13-1.21) was associated with an increased risk for ischemic stroke. Conclusion:The earlier onset age of diabetes, longer diabetes duration, and high levels of HbA1c are associated with an increased risk for ischemic stroke in type 2 diabetes patients.

To investigate the associations of serum gamma-glutamyl transferase (GGT) levels with the risk of cardiovascular disease (CVD) and its subtypes in patients with type 2 diabetes mellitus (T2DM) in Jiangsu Province.Methods:The participants were enrolled in the Comprehensive Research project regarding 'Prevention and Control of Diabetes' in Jiangsu Province. The baseline survey was conducted from 2013 to 2014, and follow-up until December 31, 2021. After excluding the participants who self-reported with chronic liver disease/stroke/coronary heart disease at baseline survey and those with incomplete information on GGT, a total of 16 147 T2DM patients were included in the final analysis. Cox proportional hazard regression models were used to calculate the hazard ratio ( HR) and their 95% CI of GGT for CVD, myocardial infarction, and stroke. Restricted cubic spline models were applied to analyze the dose-response relationship between GGT and the risk of CVD and its subtypes. Results:During the median follow-up time of 8.02 years, 2 860 CVD cases were registered, including 196 cases of myocardial infarction and 2 730 cases of stroke. Multivariate Cox proportional risk regression model indicated that compared to the lowest serum GGT level group, the highest GGT level group had a 24% increased risk of CVD ( HR=1.24, 95% CI: 1.09-1.41) and a 23% increased risk of stroke ( HR=1.23, 95% CI: 1.08-1.40). The restricted cubic spline model showed a nonlinear dose-response relationship between GGT and the risk of CVD, myocardial infarction, and stroke in T2DM patients. Conclusions:High levels of GGT may be associated with an increased risk of cardiovascular disease in T2DM patients, which needs further exploration and validation in future clinical practice.

Objective:To explore the effect of mixed reality (MR) application in the reconstruction of mandibular defects.Methods:Eighteen patients with mandibular defects were enrolled in this study, including 10 male patients and 8 female patients, whose age ranged from 27 to 45 years, and the mean age was 35.4 years. All the patients were from the Stomatological Hospital of the Fourth Military Medical University, during October 2019 to May 2021. Fibular flaps were used for the reconstruction of the mandibular defects. The patients were randomly divided into three groups, six in each group. In group one, MR-guided mandibular defect repair and reconstruction technique was used. In group two, 3D printed guide-assisted mandibular defect repair and reconstruction technique was used, and in the control group, traditional jaw defect repair and reconstruction technique was used. All the procedures were performed by the same team. Cone beam computed tomography (CBCT) was used for analysis of surgical accuracy, and questionnaires were used to evaluate the outcome of medical communication, occlusal relationship, appearance restoration, and medical experience satisfaction.Results:The mean surgical errors in the group one and group two were (1.75±0.44) mm and (1.81±0.16) mm respectively, which were both significantly lower than that in the control group (3.05±0.83) mm ( tMR=3.38, t3D=3.56, P<0.01). The medical communication (4.60±0.35, 4.52±0.28, tMR=2.90, t3D=2.77, P<0.05), occlusal relationship (4.17±0.32, 4.28±0.39, tMR=3.07, t3D=3.29, P<0.05), and medical experience satisfaction scores (4.26±0.45, 4.25±0.67, tMR=2.50, t3D=2.26, P<0.05) in the experimental groups were significantly higher than those in the control group (4.02±0.34, 3.58±0.33, 3.56±0.32, respectively). There was no significant difference in the satisfaction of appearance recovery among all the groups ( P>0.05). Conclusions:MR-guided mandibular repair and reconstruction surgery has high accuracy and is also beneficial to the recovery of occlusal relationship and medical communication.

Objective:To investigate the clinical experience of different types of femoral perforator flaps in the reconstruction of oral and maxillofacial head and neck defects.Methods:From January 2018 to January 2021, 573 patients with oral and maxillofacial head and neck defects reconstructed by femoral perforator flap were collected in the Department of Maxillofacial Oncology, the Third Affiliated Hospital of Air Force Military Medical University (age range of 21-76 years, with a male to female ratio of 1.23∶1). According to the type of perforator flap, the patients were divided into ALT group, AMT group, TFL flap group and free muscle flap group. The incidence of postoperative complications, wound healing time and drainage volume in femoral area were compared among the 4 groups.Results:The ALT flap was used in 527 cases: 22 flaps had vascular crisis, 14 flaps had infection, 8 flaps had necrosis, 519 flaps survived; the mean healing time of the wound was (14.50±3.19) days, and the mean drainage volume was (49.9±21.3) ml. 28 cases were repaired with AMT flap: 2 flaps had vascular crisis and 1 had infection. All the flaps survived; the mean healing time of the wound was (14.18±2.75) days, and the mean drainage volume was (50.3±23.0) ml. 11 cases were repaired by TFL flap: 1 flap had vascular crisis and 1 had infection. All the flaps survived. The mean healing time of the wound was (14.09±2.66) days, and the mean drainage volume was (54.1±25.0) ml. 7 cases were repaired by free muscle flap survived without vascular crisis, infection and other postoperative complications; the mean healing time of the wound was 14.14±1.86, and the mean postoperative drainage volume was (49.9±21.1) ml. There was no significant difference in complication rate (flap necrosis, vascular crisis, infection, etc.) and repair effect among 573 patients with different flap types. The postoperative follow-up was conducted for 6-24 months, and the donor area was smooth and good in appearance, without obvious scar or functional influence. The repair effect of the affected area was satisfactory.Conclusions:Although there is a certain proportion of perforator vessel variation in the femoral perforator flap, the flap can be designed freely according to different types of variation. The thigh perforator flap has an essential application value in the repair of oral and maxillofacial head and neck defects.

Objective:This meta-analysis was conducted to systematically evaluate the short-term efficacy and safety of indocyanine green fluorescence imaging guided laparoscopic liver tumor resection (FIGLTR).Methods:A systematic search was made for the literature on indocyanine green fluorescence image-guided laparoscopic hepatectomy in randomized, semi-randomized controlled trials and observational studies, and manually search published materials and conference papers in Chinese and English and trace references included in the literature.
