ABSTRACT
Objective:To evaluate the short-term influence of bilateral subthalamic deep brain stimulation (STN-DBS) in anxiety symptoms and quality of life in patients with Parkinson's disease (PD).Methods:Thirty-nine PD patients underwent bilateral STN-DBS in our hospital from August 2017 to August 2018 were chosen in our study. Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) scales were performed in these patients before and one month after surgery, and at the last follow-up, respectively. Parkinson's Disease Questionnaire-8 (PDQ-8) was performed before surgery and at the last follow-up. Statistical methods were used to analyze the differences of the above scores at different time points, and correlations between each two improvement degrees of above scores. The participants were subsequently divided into four groups based on preoperative BAI scores: no anxiety group ( n=18), mild anxiety group ( n=10), moderate anxiety group ( n=8), and severe anxiety group ( n=3); the above scales were performed. Results:(1) The BAI scores of 39 patients one month after surgery and at the last follow-up (14 [8, 20] and 9 [3, 14]) were significantly lower than those before surgery (16 [9, 27]), and the BDI scores (8[6, 16]) and PDQ-8 scores (3 [2, 6]) at the last follow-up were significantly lower than those before surgery (15 [8, 21] and 9 [6, 13], P<0.05). (2) Correlation analysis revealed that the improvement degree of BAI scores was positively correlated with that of BDI scores ( r s=0.722, P=0.000), and negatively correlated with preoperative baseline scores of BDI and PDQ-8, respectively ( r s=-0.714, P=0.000; r s=-0.378, P=0.018). (3) The BAI scores in the mild and moderate anxiety groups at the last follow-up were significantly lower as compared with the preoperative baseline BAI scores ( P<0.05). The improvement degree of BAI scores in mild, moderate, and severe anxiety groups was significantly higher than that in the no anxiety group ( P<0.05). Conclusion:The bilateral STN-DBS has considerable benefit effect on anxiety symptoms and health-related quality of life in PD patients during short-term follow-up, suggesting an involvement of STN in the pathogenesis of anxiety in PD.

ABSTRACT
The coronavirus disease 2019 (COVID-19) has become a global pandemic since its outbreak in December 2019, which posed a threat to the safety and well-being of people on a global scale. Cancer patients are at high risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and their critical morbidity and case fatality rates are high. The ablation expert committee of the Chinese Society of Clinical Oncology compiled corresponding expert recommendations. These recommendations summarize the preventive measures and management of tumor ablation treatment in medical institutions, including outpatient clinics, oncology wards, ablation operation room, and postablation follow-ups in accordance with the guidelines and protocols imposed by the National Health Commission of the People's Republic of China and the experience in management and prevention according to various hospitals. This consensus aims to reduce and prevent the spread of SARS-CoV-2 and its cross-infection between cancer patients in hospitals and provide regulatory advice and guidelines for medical personnel
ABSTRACT
Objective To cvaluate the efficacy and safety of HabibTM VesOpen intravascular radiofrequency catheter percutaneous radiofrequency ablation combined with TACE in the treatment of portal vein tumor thrombus of primary hepatocellular carcinoma.Methods Thirty-nine patients with primary hepatocellular carcinoma complicated with portal vein thrombosis were treated with HabibTM VesOpen intracavitary catheter ablation combined with TACE.The postoperative success rate,complication,blood index,α-fetoprotein (AFP),portal vein patency and tumor thrombus imaging changes were assessed.Results All of 39 patients underwent surgery successfully without occurrence of perforation,infection,hepatapostema,intra-abdominal hemorrhage nor other complications associated with surgery.Blood routine examinations (WBC,RBC,PLT) after 2 weeks and 4 weeks of surgery had no statistical difference compared with those of preoperation.Liver function indexes including ALT,AST,ALB had statistical difference before and after the surgery except for TBIL.AFP had statistical difference before and after surgery.Doppler ultrasonography after 4 weeks showed blood flow in original blocked portal vein.Enhanced CT or MR examinations after 8 weeks on the abdomen,suggested that tumors were shrinked or disappeared.Conclusion Radiofrequency catheter ablation with intracavitary radiofrequency catheter of HabibTM VesOpen is an effective method in the treatment of portal vein tumor thrombus in primary hepatocellular carcinoma.
ABSTRACT
Objective To discuss the injective method, contrast agent concentration and delay time of MSCT direct venography in lower extremity vein, in order to make optimal venographic schedule. Methods Thirty-two patients with lower extremity vein diseases underwent MSCT direct venography in using different concentration and injective rate of contrast agent, and the images were analyzed. The displaying ability of MSCT direct venography in lower extremity vein segment was compared with that of X-ray venography in 22 patients. Results Blood flow correlation constructed defect was the main factor impacting image quality of CT venography in lower extremity. The image scores between the groups of injective rate 1.5 ml/s and the group of 2.5 ml/s were statistically different (χ~2=5.495, P=0.019), whereas no difference of image score was found between the group of concentration of 25% and 15% (χ~2=3.333, P=0.068). The displaying ability of CT and X-ray venography in anterior tibial vein, posterior tibial vein, popliteal vein and femoral vein was not statistically different (χ~2=2.095, P=0.148). For iliac vein, the displaying ability of CT outstripped that of X-ray venography (χ~2=8.324, P=0.004). Conclusion With the schedule of delay time 50 s, injective rate 2.5 ml/s and concentration 45 mgI/ml (nonionic 300 mgI/ml and diluted 15%), MSCT direct venography in lower extremity can acquire satisfactory image, and its displaying ability of iliac vein is better than that of X-ray venography.
ABSTRACT
Objective To explore the technique and feasibility of using 1.5 T MR guided radiofrequency ablation (RFA) of hepatic malignant tumor. Methods Twenty three patients with 44 malignant lesions in liver confirmed by pathology were treated with 1.5 T MR guided RFA using MR compatible multipolar RF electrode. Only patients refusing open surgery or suffering from unresectable lesions were included. Of these, 11 patients had primary hepatic carcinoma and 12 patients had hepatic metastases. The mean maximal diameter of lesions was (3.3 ± 1.8)cm. Postoperative MR was performed; the ablation zone covered and exceeded 0.5 to 1.0 cm to the margin of initial tumor was considered successful. Results All ablations were successful and lesions created by radio frequency were large enough to cover the initial tumor volume in all cases. No severe complications such as biliary fistula, perforation of diaphragmatic muscle,postoperative jaundice and pneumothorax were encountered. The mean operative time was (93 ± 33 ) min.The RF electrodes appeared in MRI as low signal structure. The ablation lesions were well-defined hyperintensity in T1 WI and hypo-intensity with a thin rim of high signal intensity on T2WI and DWI. Conclusion 1.5 T MR guided RFA of hepatic malignant tumor is an effective and safe technique.

ABSTRACT
Objective To introduce the procedures and to evaluate the application value of the optical navigating interventional MR-guided percutaneous biopsies and therapies. Methods Thirty-five of 54 patients (33 males, 21 females) underwent percutaneous biopsies and 19 of 54 patients underwent percutaneous therapies under optical navigating interventional MR-guidance. The age ranged from 9 months to 78 years (mean 38.8 years). All patients were performed under a 0.23 T open MRI system (Proview, Philips Medical System) with optical navigating system (iPath 200, Philips Medical System). The needle and bone biopsy drill were MR-compatible (Daum, Germany). Results Punctures were accurate in all patients (54/54). 33 of 35 biopsies got the pathological diagnosis. All therapies (19/19) got the definitive curative effect. All patients had no obvious complications, such as severe hemorrhage, viscera or nerve injury.Conclusion iPath 200 interventional MR-guided percutaneous biopsies and therapies are accurate and safe techniques.
ABSTRACT
The purpose of this study was to examine the prevalence of disordered eating patterns (DEP) and menstrual irregularities in Chinese female athletes (n=881) and nonathletic controls (n=147), by using Eating Attitudes Test-26 (EAT-26) and written questionnaires. The athletes were divided into the following 6 categories : technical, endurance I (leanness is considered important for athletic performance) and II (leanness is less important), aesthetic, ball-game and power sports. The prevalence of DEP in the athletes estimated by EAT-26 was low (technical 1.5%, endurance I 3.3%, endurance 11 1.6%, aesthetic 3.0%, ball-game 3.0% and power sports 0.9%), and didn't significantly differ from that in nonathletic controls (0.7%) . Amenorrheic athletes were not observed in endurance I and II, aesthetic, or ball-game sports and very low prevalence rates for amenorrhea were found in the athletes in technical (0.5%) and power sports (0.4%) . These figures represent no significant differences between athletes and nonathletes in the prevalence rates of amenorrhea. It was suggested that a low prevalence of DEP in Chinese athletes stems from low socioculturally- and socioeconomically-imposed desires to be thin and low requirements for weight loss to improve athletic performance. Also, the present data suggest that the low incidence of amenorrhea in Chinese athletes is partly associated with the low prevalence of DEP.
