    Abstract: A 63-year-old woman with atrial fibrillation presented clinical symptoms and signs of acute ischemia in the right lower extremity on the 17th postoperative day after revision total hip arthroplasty of the left hip for aseptic loosening of femoral component. Aspirin was discontinued 7 days before surgery. Both computed tomography angiography and digital subtraction angiography demonstrated complete occlusion of the right common iliac artery. An emergency catheter-directed thrombolysis with urokinase combined with balloon angioplasty was performed to obtain complete patency of the right common iliac artery. Results: The patient received anticoagulation and antiplatelet therapy postoperatively and was fine at the 2-year follow-up. Conclusions: This case demonstrated that catheter-directed thrombolysis combined with balloon angioplasty could be an efficacious, minimally invasive approach for the treatment of acute embolic occlusion of the common iliac artery. Preoperative anticoagulation for patients undergoing total hip arthroplasty with long-term use of aspirin for atrial fibrillation needs further investigation.

    Abstract: A slip rate control system aimed at improving the working efficiency and driving stability of a high clearance sprayer was developed. First, the two-pump, two-anti-slip control (ASC) valve, four-motor “X” drive scheme hydraulic slip rate control system was designed, and a mathematical model of the system as well as a vehicle dynamics model were established. The system includes a slip rate control strategy, a proportional-integral-derivative control method and a fuzzy adaptive proportional-integral-derivative sprayer control method. To verify the performance of the system, a simulation model was developed using MATLAB/Simulink, and the performance of the two control methods were compared. Additionally, an actual vehicle test platform was built based on 3WPG-3000 high clearance self-propelled sprayer independently developed by the research group. The simulation results revealed that when a wheel slipped, the slip rate control system was able to control the wheel slip rate and keep it within the threshold value of 0.1, thus meeting the operating requirements of the sprayer. The field test results revealed that in field operations with a low adhesion coefficient, the system was able to maintain a nearly unchanged wheel speed in both fixed speed mode and variable speed mode, maintaining a slip rate below the target of 0.1 “when in a straight running mode” in both cases. Altogether, the results of the simulation and field test verify the stability, accuracy, and practicability of the system.

    Abstract: Breast cancer causes great threats to public health worldwide. The aim of this study was to investigate the correlation between Ki-67 expression and the hemodynamics of contrast-enhanced ultrasound (CEUS) in patients with infiltrative ductal carcinoma (IDC). CEUS was performed on 109 masses in 85 IDC cases before resection. Based on the immunohistochemical staining on the antigen Ki-67, the masses were divided into negative group, weakly positive group, positive group, and strong-positive group. Significant statistical differences were noticed in time to peak, arrive intensity, and peak intensity in the positive groups compared with the negative group. Compared with the positive groups, the negative group showed significant statistical differences in arrive intensity and peak intensity. The antigen Ki-67 was positively correlated with arrived intensity, intensity changes, and rising curve's slope. In contrast, it was negatively correlated with arrived time, time to peak, and continuous time. The hemodynamic parameters of CEUS were correlated with the expression of antigen Ki-67. On this basis, Ki-67 is an effective supplement to the diagnosis of IDC.

    Abstract: The three high-performance indicators (low retrace tolerance, long life and low vibration) of N–N type planetary gear apparatus with small tooth number difference (abbrev “N–N–PGA”) are hardly achieved simultaneously until recently. At present, the root cause analysis (RCA) and TRIZ are considered to be comprehensive and systematic new theories for technological innovation, which provides a new way to figure out the conundrum existed in the N–N–PGA. In the present study, the “root cause” of the problem is proposed with the RCA approach and two contradictions existed in the N–N–PGA have been revealed: Harmful side effect and stability of composition; harmful side effect and durability of a moving object. Besides, two reasonable principles (“Dynamicity” and “Composite materials”) for the N–N–PGA design recommended by the TRIZ method are used to eliminate these contradictions. In addition, a prototype of the obtained new type N–N–PGA design is developed for experimental testing. The obtained result demonstrates the capability of the above method for obtaining low retrace tolerance, long life, and low vibration.

    Abstract: Arsenic (As) exposure has been a global public health concern for hundreds of millions worldwide. LncRNA APTR (Alu-mediated p21 transcriptional regulator) plays an essential role in tumor growth and development. However, its function in arsenic-induced toxicological responses is still unknown. In this study, we found that the expressions of all transcripts and the transcript NR 134251.1 of APTR were increased in a dose-dependent manner in 16HBE cells treated with sodium arsenite (NaAsO 2 ). Silencing the transcript NR 134251.1 of APTR inhibited cell proliferation and induced apoptosis. However, silencing all transcripts of APTR had the opposite function to the transcript NR 134251.1. Then we examined the protein level of the proliferation and apoptosis-related genes after silencing the transcript NR 134251.1 of APTR. The results showed that silencing the transcript NR 134251.1 of APTR up-regulated the expression of transcription factor E2F1 and regulated its downstream genes involved in proliferation and apoptosis, including p53, phospho-p53-S392, phospho-p53-T55, p21, Cyclin D1, PUMA, Fas, Bim, BIK, Caspase-3, Caspase-7, and Cyt-c. In conclusion, arsenic induced APTR expression and the transcript NR 134251.1 of APTR have an opposite function to all transcripts, providing a theoretical basis for the prevention and treatment of arsenic exposure.

    In: International Journal of Stroke, SAGE Publications
    Abstract: Hypotension is recognized as a common complication after carotid artery stenting, but its incidence and the risk factors associated with it are uncertain. Therefore, we performed a systematic review and meta-analysis to investigate and identify risk factors for hypotension after surgery. Methods: We retrieved risk factors from eight databases for case-control and cross-sectional studies of hypotension after carotid artery stenting according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines on 28 November 2022. Data were analyzed by using R4.2.1 and Review Manager 5.3. Results: A total of 2843 samples were searched, and 17 publications were included in the analysis. The meta-analysis results showed that the incidence of hypotension after surgery was 28.6% (95% confidence interval [CI] (0.225, 0.347)). Age ⩾ 65 years (odds ratio [OR]  = 4.55, 95% CI (2.50, 8.29), P  〈  0.00001), stenosis site (bulb) (OR = 4.41, 95% CI (2.50, 7.79), P  〈  0.00001), severe stenosis (OR = 3.56, 95% CI (1.62, 7.85), P = 0.002), stenosis proximity (⩽ 10 mm) to bifurcation (OR = 2.69, 95% CI (1.74, 4.15), P  〈  0.00001), calcified plaques (OR = 4.64, 95% CI (1.93, 11.14), P = 0.0006), post-balloon dilation (OR = 5.95, 95% CI (2.31, 15.31), P = 0.0002), bilateral carotid stenting (OR = 30.51, 95% CI (2.33, 399.89), P = 0.009), and intravenous fluid intake/mL on the first postoperative day (mean difference = 444.99, 95% CI (141.40, 748.59), P = 0.004) were risk factors for hypotension after surgery. Conclusions: A high incidence of hypotension was observed after carotid artery stenting. Age, stenosis site, severe stenosis, stenosis proximity to bifurcation, calcified plaques, post-balloon dilation, type of surgery, and intravenous fluid intake were identified as risk factors.

    Abstract: Myxedema coma is a rare and life-threatening endocrine emergency characterized by abnormalities in multiple organ systems. A 32-year-old woman with prolonged undiagnosed severe hypothyroidism was referred to our hospital owing to lower abdominal pain and menopause for more than 3 months. She underwent exploratory laparotomy and induced abortion under general anesthesia, and developed severe hypoxemia after extubation. She was diagnosed with myxedema coma, and was subsequently discharged with a good prognosis following treatment. This case suggests that myxedema coma should be considered a potential etiology of peri-operative hypoxemia. The findings in this case emphasize the importance of anesthesiologists’ comprehensive understanding of myxedema coma. Prompt diagnosis followed by treatment is essential to reduce the mortality rate associated with this condition.

    Abstract: 3D braided composites have been increasingly applied in the aerospace, automotive, and other high-tech industries as primary load-bearing structures due to their excellent integrated performance. Evaluation on the failure behavior of 3D braided composites subjected to off-axial loading still remains a challenging topic. We present in this paper a meso-scale finite element (FE) model containing void defects for investigating the off-axial tensile behavior of 3D braided composites. The FE model is verified and the effects of porosity are discussed in on-axial tensile conditions, and then it is executed to predict the mechanical response in general off-axial tensile cases. The strength properties of 3D braided composites, and more importantly the progressive damage behavior under typical off-axial loadings, are analyzed in detail. It is found that the off-axial tensile strength and corresponding failure mode of 3D braided composites are mainly affected by the braiding angle of specimen. The proposed FE modeling provides an appropriate reference for the numerical study of void defects and off-axis load problems in other textile composites.

    Abstract: The auto-follow row technology is the basic technology to realize the uncrewed operation of corn harvesters, which helps to improve the quality and efficiency of corn harvest. A deviation detection sensor and an auto-follow row system are designed to address the difficulty for corn harvesters to harvest the corn sowing with different row spacing. The auto-follow row system is comprised of the auto-follow row controller, two deviation detection sensors, sensors for acquiring the state of the corn harvester, and the hydraulic steering system. The deviation detection sensor uses the touch rod to detect the lateral deviation and sends it to the auto-follow row controller through the Controller Area Network (CAN) bus. The auto-follow row controller obtained the lateral deviation, calculated the target steering angle according to the pure pursuit method based on the yaw angle estimation model and fuzzy control model, and adjusted the posture of the harvester by controlling the steering actuator. Two types of corn harvesters were reformed and mounted the auto-follow row system for simulation and field tests. The average errors of the auto-follow row system in the simulation tests and the field tests were 0.040 m and 0.046 m, respectively. The relative deviations within ±0.075 m were 98.33% and 97.22%, respectively, which met the operating requirements of corn harvesters. The test results show that the auto-follow row system can be applied to many kinds of corn harvesters and provide a reference for designing a completely unmanned system for corn harvesters.

    Abstract: Healthy first-degree relatives of patients with major depression are at an elevated risk of developing depression, and regional cerebral blood flow (CBF) alterations are observed in patients with depression. Therefore, in a 33-month follow-up study, we used arterial spin labeling-magnetic resonance imaging (ASL-MRI) to investigate quantitative CBF before and after the diagnosis of depression in healthy young adults with and without first-degree relatives with major depression (FH + and FH−, respectively). In cross-sectional and longitudinal CBF comparisons, CBF in the right amygdala was increased or decreased. Additionally, a significant correlation was observed between the altered CBF in the right amygdala and the scores on the 17-item Hamilton Depression Rating Scale (HDRS) in the FH + group. Furthermore, logistic regression and receiver operating characteristic curve analyses showed that increased CBF in the right amygdala at baseline predicted the subsequent onset of depression in the FH + group. Our results suggest that among healthy young adults with a familial risk of depression, those who exhibit increased CBF in the amygdala are susceptible to developing this disease.
