Obsessive-compulsive disorder (OCD) is characterized by recurrent episodes of intrusive thinking and/or behavior, persistent and variable symptoms, and chronic recurrence. It is clearly recommended in the OCD treatment guidelines that psychotherapy can effectively improve clinical symptoms and play an important role in maintaining long-term efficacy. However, previous research and clinical practice paid little attention to the application of psychological interventions in OCD.Currently, there is insufficient understanding of psychotherapy for OCD, especially the proven first-line exposure and response prevention therapy (ERP), cognitive-behavioral therapy, and Morita therapy.Due to limited resources, they have not received effective intervention. Therefore, this article reviews the relevant research on psychological therapy intervention for OCD in recent years, summarizes the intervention effects of different psychological therapy methods on OCD and further elaborates on possible therapeutic mechanisms.Based on this, combined with the existing research, this article clarifies the effect of various behavioral psychological interventions and their combined treatment, and explores group and online forms of psychological intervention in order to increase the accessibility of psychotherapy for OCD patients.

Objective:To evaluate the safety and early-to-mid-term efficacy of Cheatham-Platinum (CP) covered stent in treating primary coarctation of the aorta (COA) in children.Methods:?A retrospective self-controlled study was conducted on 20 pediatric patients with primary COA who underwent CP covered stent implantation at the Department of Pediatric Cardiology, Guangdong Provincial People′s Hospital, between January 2006 and December 2024. Clinical baseline characteristics, procedural details, and postoperative follow-up records were collected. Changes in aortic pressure gradients before and after the procedure, as well as the complication rates, were assessed. Comparisons between pre-and post-operative parameters were performed using paired Student′s t-tests and rank sum test. Results:Among the 20 patients, 14 were males and 6 were females, with the age of 12 (11, 13) years and the weight of 43 (36, 49) kg. All of the patients underwent successful implantation of CP-covered stents, with a technical success rate of 100%. The immediate peak gradient across the coarctation segment decreased significantly from 49 (33, 58) mmHg (1 mmHg=0.133 kPa) preoperatively to 3 (0, 5) mmHg postoperatively ( Z=3.92, P<0.001). The narrowest vessel diameter increased from (5.6±3.2) mm preoperatively to (16.9±5.4) mm postoperatively ( t=14.73, P<0.001). Following stent implantation, all patients exhibited a significant reduction in blood pressure, with left upper arm systolic blood pressure decreasing from(141±19) mmHg preoperatively to (122±11) mmHg postoperatively ( t=4.47, P<0.001). Immediate complications occurred in 3 cases: one pseudoaneurysm, one left subclavian artery occlusion, and one access site hematoma. During a follow-up period of 2 (1, 3) years, 16 patients maintained blood pressure within the normal range, while 4 had residual hypertension. Restenosis occurred in 3 patients: 1 patient underwent re-dilation at 24 months postoperatively; and the other 2 patients, who exhibited an upper-to-lower limb systolic blood pressure gradient <20 mmHg, did not require intervention at the time of reporting. All stents remained well-positioned. Follow-up CT angiography at 1 year in 8 patients demonstrated stent patency without evidence of fracture or aneurysm. Conclusion:CP-covered stent demonstrates high safety and favorable short-to-mid-term efficacy in treating primary COA in children.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Flagella are the main motility structure of Clostridioides difficile that affects the adhesion, colonization, and virulence of C. difficile in the human gastrointestinal tract. The FliL protein is a single transmembrane protein bound to the flagellar matrix. This study aimed to investigate the effect of the FliL encoding gene flagellar basal body-associated FliL family protein (fliL) on the phenotype of C. difficile. The fliL gene deletion mutant (ΔfliL) and its corresponding complementary strains (: : fliL) were constructed using allele-coupled exchange (ACE) and the standard molecular clone method. The differences in physiological properties such as growth profile, antibiotic sensitivity, pH resistance, motility, and spore production ability between the mutant and wild-type strains (CD630) were investigated. The ΔfliL mutant and the : : fliL complementary strain were successfully constructed. After comparing the phenotypes of strains CD630, ΔfliL, and : : fliL, the results showed that the growth rate and maximum biomass of ΔfliL mutant decreased than that of CD630. The ΔfliL mutant showed increased sensitivity to amoxicillin, ampicillin, and norfloxacin. Its sensitivity to kanamycin and tetracycline antibiotics decreased, and the antibiotic sensitivity partially returned to the level of CD630 strain in the : : fliL strain. Moreover, the motility was significantly reduced in the ΔfliL mutant. Interestingly, the motility of the : : fliL strain significantly increased even when compared to that of the CD630 strain. Furthermore, the pH tolerance of the ΔfliL mutant significantly increased or decreased at pH 5 or 9, respectively. Finally, the sporulation ability of ΔfliL mutant reduced considerably compared to the CD630 strain and recovered in the : : fliL strain. We conclude that the deletion of the fliL gene significantly reduced the swimming motility of C. difficile, suggesting that the fliL gene is essential for the motility of C. difficile. The fliL gene deletion significantly reduced spore production, cell growth rate, tolerance to different antibiotics, acidity, and alkalinity environments of C. difficile. These physiological characteristics are closely related to the survival advantage in the host intestine, which is correlated with its pathogenicity. Thus, we suggested that the function of the fliL gene is closely related to its motility, colonization, environmental tolerance, and spore production ability, which consequently affects the pathogenicity of C. difficile.

Objective To investigate the prevalence of hepatitis D virus (HDV) infection among patients with chronic hepatitis B virus (HBV) infection in some regions of China. Methods Serum samples were collected from 3 131 patients with chronic HBV infection in 10 provinces, cities, and autonomous regions of China from March 2021 to June 2022, and anti-HDV IgG ELISA was used for the detection of all serum samples. Nested reverse transcription-polymerase chain reaction (nRT-PCR) was used to detect HDV RNA in anti-HDV IgG-positive samples, and the nRT-PCR amplification products of HDV RNA-positive samples were sequenced and analyzed to determine HDV genotype. The clinical features of anti-HDV IgG-positive patients were analyzed. The Mann-Whitney U rank sum test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher's exact test was used for comparison of categorical data between two groups. Results The positive rate of anti-HDV IgG in the 3 131 patients with chronic HBV infection was 0.70% (22/3 131), and that in the patients with chronic HBV infection in Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region, Beijing, and Hunan Province was 1.81% (16/886), 0.88% (2/226), 0.28% (2/708), and 1.00% (2/200), respectively; the patients with chronic HBV infection in Inner Mongolia Autonomous Region had a significantly higher positive rate of anti-HDV IgG than those in Beijing ( P =0.004), and there was no significant difference between the other regions ( P > 0.05). Clinical features of the patients with chronic HBV infection in Inner Mongolia Autonomous Region showed that compared with the anti-HDV IgG-negative group, the anti-HDV IgG-positive group had a significantly higher proportion of patients with Mongol nationality ( P =0.001), abnormal alanine aminotransferase ( P =0.007), or antiviral treatment ( P =0.029), as well as a significantly lower median HBV DNA level ( P =0.030). A total of 19 HDV RNA-positive samples were identified, all of which had HDV genotype 1. Conclusion The prevalence rate of HDV varies greatly across different regions of China, with a higher prevalence rate of HDV in patients with chronic HBV infection from Inner Mongolia Autonomous Region. HDV genotype 1 is the predominant genotype in some provinces and cities of northern China.

Objective To study the effect of Snsong Yangxin capsule and metoprolol sustained release tablet on the curative effect and the levels of BNP and HR in the elderly coronary heart disease (CHD) arrhythmia patients. Methods It selects 108 patients with coronary heart disease and arrhythmia in elderly patients were divided into observation group (54 cases) and control group (54 cases). The control group was treated with metoprolol sustained-release tablets, and the observation group was treated with Shensong Yangxin capsule and metoprolol sustained-release tablets. The curative effect of two groups and the changes of BNP and HR levels before and after treatment were observed and compared. Results The treatment effect, times of contraction, frequency of cardiac fibrillation, frequency of defect, load, time, blood pressure and BNP of the observation group were significantly better than those of the control group (P<0.05). Conclusion For elderly patients with coronary heart disease arrhythmia, the treatment of Shensong Yangxin capsule combined with metoprolol sustained release tablets is effective. It can significantly improve the patient's heart rate, restore the blood supply to the heart, improve the blood pressure and BNP, with less adverse reactions, safe and reliable, and worthy of promotion.

Objective To analyze the clinical characteristics and follow-up data of catheter ablation of recurrent atrial tachycardias (ATs) after Mini-Maze surgery,and to explore prognostic factors for recurrence.Methods 59 patients in Guangdong General Hospital with ATs post Mini-Maze and concomitant open-heart surgery from April.2010 to June.2015 were included.According to high density precise mapping,activation mapping,voltage mapping and entrainment mapping,they underwent electrophysiological study and ablation which was guided by three-dimensional mapping system.All patients were followed up regularly.We explored the prognostic factors for recurrence by the Cox regression analysis.Results There were 88 types of ATs being mappedwith mean (1.49 ± 0.75) types of ATs identified per case.Most ATs were macro-reentry ATs(67/88,76.1％)and focal ATs (20/88,22.7％),respectively.56 patients (94.9％) achieved immediate ablation success.In a mean follow-up of (30.8 ± 17.7) months,recurrences were observed in 12 patients after the first time catheter ablation.Recurrent time was 3.5 (1.3,12.0) months and the overall ablation success rate was 74.6％ (44/59).6 patients received second ablation and the achievement of freedom from arrhythmias reached 79.7％ (47/59).Multivariate analysis showed that the LA diameter was the independent predictor for recurrence (HR 1.108,95％ CI 1.002 to 1.226,P =0.045).Conclusion Catheter ablation of ATs post Mini-Maze with concomitant surgery is save and feasible.LA diameter is the independent predictor for recurrence.
