Background and purpose:Radiofrequency ablation (RFA) was one of the best combined treatments for hepatocarcinoma. CT was commonly used to evaluate treatment response and recurrent disease. However it was diffi cult to evaluate treatment effectiveness of RFA and to detect recurrent nodule especially the size below 1cm. Digital subtraction arteriography(DSA) may provide fi nal diagnosis of recurrent nodule after RFA for hepatocarcinoma. Our purpose was to analyze the signs of DSA after RFA for hepatocarcinoma in order to provide possible reference for treatment effectiveness and the imaging follow-up methods. Methods:17 patients with primary liver cancer (n=15) or hepatic metastasis(n=2) were enrolled in this study. Common hepatic arteriography or super-selective angiography of suspicious tumor area were performed on all patients. Results:On DSA, most ablated regions presented as round or ovoid low density areas with no stain. At the peripheral zone of the lesion, fi ve signs after RFA could be found: Stain of localized granulation tissue, arterio-portal fi stula, hemorrhage, recurrence and no abnormal fi ndings. Local or intrahepatic recurrence occurred in 9 cases. Conclusion:Hepatic DSA has great value in detecting local recurrence of hepatic tumor after RFA treatment. DSA is superior to CT in detecting marginal or intrahepatic recurrent nodule below 1 cm.

Objective To determine the feasibility and safety of transprostatic utricle seminal vesiculoscopy in the treatment of hemospermia. Methods Totally 11 patients with hemospermia, mean age of (46.6 ± 3.5) years, ranging from 38 to 68 years, for 3 months admitted from September 2012 to August 2015 were enrolled, Their main manifestations were hemospermia. Painful ejaculation was observed in 7 patients, and perineal and testicular pain occured in 4 patients. They all underwent transprostatic utricle seminal vesiculoscopy, and then were followed up for 3 to 6 months. Results Ten patients were operated successfully, but 1 patient failed. The operation revealed that the causes of hemospermia were seminal vesiculitis in 8 cases, seminal vesiculitis accompanied with seminal calculi in 2 cases, and ejaculatory duct cyst in 1 case. Operation time was (29.2 ± 3.2) min ( ranging from 25 to 37 min) , and hospital stay was 2 d ( from 2 to 4 d). Hemospermia disappeared in 10 patients within 1 month of surgery, and hemospermia recurrence was observed in 1 patient within 6 months. The patient was treated with transprostatic utricle Holmium laser incision, then hemospermia was dispeared,Two cases of postoperative epididymitis were cured after one week of antibiotic treatment. Conclusions Seminal vesiculoscopy is a safe and effective to treat hemaospermia.

Objective: To evaluate the treatment efficacy of reverse flaring technique applied by two rotary instruments, Hero 642 and ProTaper, on complicated molar root canal preparation. Methods: 100 molars with curved root canals (maximum curved angle ≥25 degrees) suffered from pulpitis or periapicities were randomly divided into two groups. In experimental group reverse flaring technique was applied by rotary instruments while in control group reverse flaring technique was not adopted. 50 experimental teeth with curved canals were operated with K files, Hero 642 and ProTaper in sequence. Lateral condensation obturation method was utilized in both groups. Root canal preparation and obturation efficiency were evaluated by X-ray, root canal preparation time and complication incidence (1 year follow-up rate was 95%). Results: Reverse flaring technique applied by Hero 642 and ProTaper Ni-Ti rotary instruments on complicated (curved) root canal preparation in group A demonstrated better root canal coning and smoothness, without instrument fractures, while instrument fractures occurred in control group. Significant difference was found in exact root canal obturation rate and not enough full rate, root canal smoothness and postoperative pain between two groups(P<0.05). Conclusion: Reverse flaring technique applied by Hero 642 and ProTaper NI-Ti rotary instruments indicates complementary potencies, demonstrating satisfactory root canal shape and obturation effectiveness, and lower complication incidence. Reverse flaring technique applied by Ni-Ti rotary instruments is apt for medium/severe curved root canal preparation and worthy of clinical application.

OBJECTIVE: The prior functional MRI studies have demonstrated significantly abnormal activity in the bilateral superior temporal gyrus (STG) of anxiety patients. The purpose of the current investigation was to determine whether the abnormal activity in these regions was related to a loss of functional connectivity between these regions. MATERIALS AND METHODS: Ten healthy controls and 10 anxiety patients underwent noninvasive fMRI while actively listening to emotionally neutral words alternated by silence (Task 1) or threat-related words (Task 2). The participants were instructed to silently make a judgment of each word's valence (i.e., unpleasant, pleasant, or neutral). A coherence analysis was applied to the functional MRI data to examine the functional connectivity between the left and the right STG, which was selected as the primary region of interest on the basis of our prior results. RESULTS: The data demonstrated that the anxiety patients exhibited significantly increased activation in the bilateral STG than the normal controls. The functional connectivity analysis indicated that the patient group showed significantly decreased degree of connectivity between the bilateral STG during processing Task 2 compared to Task 1 (t = 2.588, p = 0.029). In addition, a significantly decreased connectivity was also observed in the patient group compared to the control group during processing Task 2 (t = 2.810, p = 0.012). CONCLUSION: Anxiety patients may exhibit increased activity of the STG but decreased functional connectivity between the left and right STG, which may reflect the underlying neural abnormality of anxiety disorder, and this will provide new insights into this disease.

Diffusion MRI (dMRI) has been widely utilized to probe the random motion of water molecules in tissues. In a dMRI acquisition protocol, diffusion weighting or b-value is one of the most important parameters to consider. In recent years, high and ultrahigh b-values have become popular partly due to advances in hardware. In this mini-review, we will discuss impacts of high/ultrahigh b-values in three different areas: brain microstructure, tractography, and clinical applications. We will emphasize advantages of high b-value in probing diffusion within highly restricted regions or fine structures with enhanced diffusion contrast. A short summary is included at the end of each section to illustrate both advantages and disadvantages of using a high/ultrahigh b-value for each purpose.

Objective:
This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress.Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioningand psychological distress.
Methods:
Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item GeneralHealth Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzedusing multiple linear regression analysis and path analysis.
Results:
The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factorsof psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by generalwell-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated byexercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029).
Conclusion
The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercisewere associated with psychological distress. Family functioning could affect psychological distress partially by affecting general wellbeing.Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.Psychiatry Investig 2020;17(4):356-365

BACKGROUND:Digital three-dimensional reconstruction technology is gradually applied to orthopedic diseases with the advantages of visualization,accuracy and non-invasiveness,but there is less evidence-based support for its use in artificial hip hemiarthroplasty for intertrochanteric fractures of the femur in the elderly. OBJECTIVE:To investigate the application value and economic effects of digital three-dimensional reconstruction techniques in artificial hip hemiarthroplasty of intertrochanteric fractures of the femur in the elderly. METHODS:One hundred and thirty elderly patients with intertrochanteric femur fractures admitted to Zunyi First People's Hospital from January 2019 to December 2022 were selected and randomly divided into a control group(n=65)and an observation group(n=65).Artificial hip hemiarthroplasty was performed in both groups.The control group adopted the film template measurement method for manual preoperative planning while the observation group adopted a digital three-dimensional reconstruction technique.Preoperative planning and intraoperative actual application of prosthesis compliance rate,fibrinogen,D-dimer,bilateral femoral eccentric distance difference,bilateral lower limb length difference,Harris hip function score,visual analog scale score,excellent and good rate of hip function,complications,and hospitalization cost were observed in both groups. RESULTS AND CONCLUSION:(1)The proportion of acetabular side and femoral side prosthesis in grade 0(fully compliant)was higher in the observation group than that in the control group(P<0.05).(2)Fibrinogen and D-dimer levels in the observation group were lower than those in the control group 3 days after surgery(P<0.05).(3)The difference in bilateral femoral eccentric distance and the difference in bilateral lower limb length in the observation group were smaller than those in the control group immediately after surgery(P<0.05).The differences in Harris and visual analog scale scores were not significantly different between the two groups preoperatively,6 and 12 months postoperatively(P>0.05).There was no significant difference in excellent and good rate of hip function between the two groups 12 months postoperatively(P>0.05).(4)There was no significant difference in the complication rate between the two groups(P>0.05).The hospitalization cost of the observation group was higher than that of the control group(P<0.05).(5)It is indicated that digital three-dimensional reconstruction technology applied in artificial hip hemiarthroplasty of intertrochanteric femoral fracture in the elderly can not only accurately determine the prosthesis type before surgery,but also accurately reconstruct the bilateral lower limbs offline,but its hospitalization cost is high.
