ABSTRACT

Objective:To investigate the neurobiochemical metabolites of caudate nucleus and thalamus in patients with obsessive-compulsive disorder and their relationship with obsessive-compulsive symptoms.Methods:From April 2019 to January 2022 in Beijing Anding Hospital, totally 25 untreated patients with obsessive-compulsive disorder were recruited, and 20 healthy controls matched with gender, age and educational background were recruited for the study.The maps of neurobiochemical metabolites of patients and normal controls were collected by hydrogen proton magnetic resonance spectroscopy.With bilateral caudate nucleus and thalamus as brain regions of interest.The relative concentrations of N-acetylaspartic acid (NAA), glutamic acid (Glu) and γ-aminobutyric acid (GABA) were fitted by LCModel software.At the same time, the clinical symptoms of patients were evaluated with Yale-Brown obsessive-compulsive scale (Y-BOCS) and Hamilton anxiety scale (HAMA). SPSS 20.0 software was used for statistical analysis.Independent double sample t-test was used to compare the differences of different nerve biochemical metabolite concentrations between patients with obsessive-compulsive disorders and healthy controls.Pearson correlation analysis was used to explore the correlation between biochemical metabolite concentrations and clinical symptoms. Results:The Glu concentration in the left thalamus of patients with obsessive-compulsive disorder (3.97±0.41) was higher than that of the control group (3.66±0.55)( t=-2.11, P<0.05), while the NAA concentration was (4.87±0.47)lower than that of the control group (5.15±0.44)( t=2.05, P<0.05). The GABA concentrations in the right caudate nucleus (0.50±0.18) and thalamus (0.80±0.19) were lower than those in the control group ((0.63±0.23), (0.96±0.24))( t=2.08, 2.36, both P<0.05). Pearson correlation analysis showed that the Glu concentration in the left caudate nucleus of patients with obsessive-compulsive disorder was positively correlated with the total score of Y-BOCS( r=0.46, P<0.05). Spearman correlation analysis showed that Glu concentration in the right caudate nucleus was positively correlated with the total score of HAMA in patients with obsessive-compulsive disorder ( r=0.46, P<0.05). Conclusion:NAA, Glu and GABA metabolism in caudate nucleus and thalamus are abnormal in patients with obsessive-compulsive disorder, and Glu concentration is positively correlated with the severity of obsessive-compulsive and anxiety symptoms.

ABSTRACT

The hepatic caudate lobe is located in the deep back area of the liver. Due to the unique anatomical position of hepatic caudate lobe, surgical treatment for tumor of hepatic caudate lobe is particularly difficult. Non-surgical treatment, such as ablation, transarterial embolization, etc, is also challenging for tumor of hepatic caudate lobe, and the therapeutic effect is inferior to that of surgery. Therefore, surgical resection is the only treatment for tumor of hepatic caudate lobe. The authors discuss the research history of hepatic caudate lobe, the problems of laparoscopic technique in hepatic caudate lobe resection, etc, in order to provide a theoretical basis for improving the concept of accuracy of laparoscopic caudate lobectomy.

ABSTRACT

Aims: The goal of this study was to analyze the puncture routes of imaging-guided thermal ablation for tumors of the hepatic caudate lobe. Materials and Methods: The imaging-guided thermal ablation puncture routes of 12 cases of hepatic caudate lobe tumors were collected in our hospital from January 2013 to February 2019. The puncture routes were retrospectively analyzed, and the experience of thermal ablation therapy for hepatic caudate lobe tumors was summarized. Results: Among the 12 cases of hepatic caudate lobe tumors, puncture routes were divided into the anterior (through the left lobe of the liver) approach (six cases), the right hepatic approach (five cases), and the transthoracic approach (one case). Different ablation electrodes were selected according to the puncture route and method of guiding. No serious postoperative complications were noted. Conclusion: The hepatic caudate lobe is surrounded by the inferior vena cava, hepatic vein, and hepatic hilum, leading to great difficulties and risks in performing minimally invasive treatment of hepatic caudate lobe malignancies. Therefore, selecting an appropriate puncture route is an important factor in the success of the treatment

ABSTRACT

PURPOSE: Complete removal of the caudate lobe, which is sometimes necessary, is accomplished via isolated caudate lobectomy or hepatectomy that includes the caudate lobe. It is impossible, however, to confirm the right and ventral margins of the caudate lobe by preoperative imaging. This study was undertaken to determine whether we could identify the right and ventral margins of the caudate lobe preoperatively using Synapse 3D visualization software. METHODS: Ninety-four preoperative 3-dimensional (3D) computed tomographic images (1-mm slices) of the liver from candidate donors were examined. The images of the caudate lobe were subjected to a counter-staining method according to Synapse 3D to delineate their dimensions. We first examined whether the right margin of the caudate lobe exceeded the plane formed by the root of the right hepatic vein (RHV) and the right side of the inferior vena cava (IVC). Second, we determined whether the ventral margin of the caudate lobe exceeded the plane formed by the root of the middle hepatic vein (MHV) and the root of the RHV. RESULTS: For the right margin, 17 cases (18%) exceeded the RHV-IVC plane by a mean of 10.2 mm (range, 2.4–27.2 mm). For the ventral margin, 28 cases (30%) exceeded the MHV-RHV plane by a mean of 17.4 mm (range, 1.2–49.1 mm). CONCLUSION: Evaluating the anatomy of caudate lobe using Synapse 3D preoperatively could be helpful for more precise anatomical resection of the caudate lobe.

ABSTRACT

Objective To investigate the safety, efficacy and the key points of ultrasound-guided percutaneous radiofrequency ablation (RFA) in treatment of caudate lobe liver tumor. Methods The clinical data of 30 patients with caudate lobe liver tumor (57 lesions, 33 caudate lobe lesions) in the Affiliated Tumor Hospital of Zhengzhou University from January 2017 to December 2018 were retrospectively analyzed. All the patients were treated with ultrasound- guided percutaneous radiofrequency ablation. The puncture approach and single-needle or double-needle radiofrequency ablation were chosen according to the lesion location. The efficacy after treatment was evaluated according to the imaging examination. The deadline of follow-up was January 31, 2019, and the median follow-up time was 10 (1 to 20) months. After ablation, CT/MR was performed to evaluate whether the lesions were completely ablated. The effect of treatment and short-term complication were recorded. Results Thirty patients were successfully treated with ultrasound-guided percutaneous radiofrequency ablation. Among the 33 caudate lobe lesions, complete ablation rate at one time was 81.8% (27/33); local tumor progression rate after treatment was 12.1% (4/33), and the median time was 2.5 months. The new lesion rate was 26.7% (8/30), and the median time was 3.0 months. Two patients had significant abdominal pain, 1 patient had fever, 1 patient had hypoxemia during the ablation, and total incidence of complication was 13.3% (4/30). There was no bile leakage, gastrointestinal tract injury, uncontrollable bleeding and other serious complications and related deaths. Conclusions For the caudate lobe liver tumor, ultrasound-guided percutaneous radiofrequency ablation is safe and effective. It is necessary to select the appropriate puncture approach, avoid the intrahepatic duct reasonably and master the key points of ablation.

ABSTRACT

OBJECTIVE: Prior functional magnetic resonance imaging (fMRI) work has revealed that children/adolescents with disruptive behavior disorders (DBDs) show dysfunctional reward/non-reward processing of non-social reinforcements in the context of instrumental learning tasks. Neural responsiveness to social reinforcements during instrumental learning, despite the importance of this for socialization, has not yet been previously investigated. METHODS: Twenty-nine healthy children/adolescents and 19 children/adolescents with DBDs performed the fMRI social/non-social reinforcement learning task. Participants responded to random fractal image stimuli and received social and non-social rewards/non-rewards according to their accuracy. RESULTS: Children/adolescents with DBDs showed significantly reduced responses within the caudate and posterior cingulate cortex (PCC) to non-social (financial) rewards and social non-rewards (the distress of others). Connectivity analyses revealed that children/adolescents with DBDs have decreased positive functional connectivity between the ventral striatum (VST) and the ventromedial prefrontal cortex (vmPFC) seeds and the lateral frontal cortex in response to reward relative to non-reward, irrespective of its sociality. In addition, they showed decreased positive connectivity between the vmPFC seed and the amygdala in response to non-reward relative to reward. CONCLUSION: These data indicate compromised reinforcement processing of both non-social rewards and social non-rewards in children/adolescents with DBDs within core regions for instrumental learning and reinforcement-based decision-making (caudate and PCC). In addition, children/adolescents with DBDs show dysfunctional interactions between the VST, vmPFC, and lateral frontal cortex in response to rewarded instrumental actions potentially reflecting disruptions in attention to rewarded stimuli.

ABSTRACT

Background: To study the morphology of the caudate lobe of liver. The caudate lobe is visible on the posterior surface, bounded on the left by the fissure for the ligamentum venosum, below by the porta hepatis and on the right by the groove for the inferior vena cava. Above, it continues into the superior surface on the right of the upper end of the fissure for the ligamentum venosum. Below and to the right, it is connected to the right lobe by a narrow caudate process, which is immediately behind the porta hepatis and above the epiploic foramen. Below and to the left, the caudate lobe has a small rounded papillary process. Taking into consideration clinical importance of this lobe in metastasis, cirrhosis and hepatic resections a morphological study was carried out on caudate lobe. Methods: This study was undertaken on 36 cadaveric livers available in the Department of Anatomy of Shri Ram Murti Smarak Institute of Medical Sciences, Bareilly to study the morphometery of caudate lobe of liver using vernier caliper. Results: Various shapes of the caudate lobe were observed, rectangular being the commonest. Conclusion: Knowledge of variations of caudate lobe may be important to anatomists and morphologists for new variant, embryologists for new developmental defect, clinicians for diseases, surgeons for planning surgery involving liver, and imagery specialists for avoiding misinterpretation of CT and MRI.

ABSTRACT

Objective To evaluate functional activity of the subcortical nuclei in Wilson's disease (WD) using resting state functional MRI (rs-fMRI),and to evaluate damage to the functional conjunction in the extracorticospinal tract in WD patients.Methods Twenty-two patients with WD (between January 2015 and January 2016),including 18 with cerebral type and 4 with hepatic type,and 20 age-matched healthy controls were enrolled.Neurological symptoms were scored using the modified Young Scale.Patients with cerebral type WD were divided into 4 subgroups.All study subjects underwent rs-fMRI of the brain.The values of amplitude of low-frequency fluctuation (ALFF) and regional homogeneity (REHO) in the thalamus,caudate nucleus,putamen and globus pallidus were determined.The relationships between rsfMRI metrics and clinical status were evaluated.Results ALFF values were lower in the caudate nucleus,putamen and right thalamus of WD patients than in controls (t =-3.07,-3.00,-3.12,-2.46,-2.20;P =0.005,0.006,0.004,0.020,0.036),while REHO values were lower in the left caudate nucleus and left thalamus of WD patients (t =-2.38,-2.16;P =0.025,0.040).In the caudate nucleus (P =0.032,0.029,0.023),thalamus (P =0.022,0.041,0.035) ALFF values were lower in group 4 than in other groups.REHO values of the putamen (P =0.040,0.017,0.040) and thalamus (P =0.024,0.029 7,0.041) were higher in group 4 than in other groups.ALFF values in the caudate nucleus (t =-0.29,P=0.037),and thalamus (t =-1.77,P =0.042) were lower,and REHO values in the caudate nncleus (t =-1.46,P =0.040) were lower,in patients of cerebral type than in hepatic type patients.Conclusions The damage to the functional activity of the subcortical nuclei may occur in the WD patients.The functional activity of nuclei may be different between hepatic and cerebral type patients.Damage to the activity of neurons in the putamen and thalamus may correlate with psychiatric symptoms in WD patients.
