Objective:This study aimed to evaluate the therapeutic effect of intratympanic injection of ganglioside in patients with refractory sudden deafness. Methods:A total of 120 patients with sudden deafness, aged 18-65 years, whose onset was within 11-42 days, failed to respond to conventional treatment, and had an average hearing threshold（500-4 000 Hz）>60 dB were selected. They were prospectively and randomly divided into a control group of 61 cases and an experimental group of 59 cases. The control group was treated according to the recommended protocol of the Chinese Medical Association（postauricular injection of methylprednisolone）, while the experimental group was treated with intratympanic injection of monosialotetrahexosylganglioside sodium+postauricular injection of methylprednisolone. Both groups were simultaneously administered oral ginkgo biloba extract and citicoline tablets. Hearing was re-examined two weeks after the completion of treatment, and the therapeutic effects of the two different treatment methods were compared and analyzed. Results:The effective rate was 29.51% in the control group and 54.24% in the experimental group（P<0.01）. The average hearing threshold improved by 11.57 dB HL in the control group and 22.50 dB HL in the experimental group（P<0.05）. Conclusion:The combination of postauricular injection of methylprednisolone and intratympanic injection of ganglioside is more effective than postauricular injection of methylprednisolone alone in the treatment of refractory sudden deafness. The earlier the treatment, the better the therapeutic effect.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Chronic aortic stenosis and regurgitation can cause left ventricular remodeling.Whether these changes are reversible and their reversibility after valve replacement are the main determinants affecting the timing and prognosis of surgery.Imaging techniques are commonly used to evaluate myocardial structure and function,in which echocardiography and enhanced CT are helpful to evaluate artificial flap function and monitor left ventricular deformation,while cardiac MR and PET/CT are helpful to identify the progression and regression of postoperative cardiac fibrosis.The combined application of these new techniques can improve clinical outcomes by early diagnosis and non-invasive detection of postoperative left ventricular reverse remodeling.This paper reviews the evaluation and application of multi-modal imaging techniques for left ventricular reverse remodeling after aortic valve replacement.

Objective:To analyze the expression of topoisomerase Ⅱα(Topo Ⅱα) and cyclin G1 in gastric adenocarcinoma and their relationship with clinicopathological characteristics and Helicobacter pylori (Hp) infection.Methods:From May 2018 to May 2022, 217 gastric adenocarcinoma tissues and adjacent normal tissue samples were collected in Lu′an Hospital of Traditional Chinese Medicine. The streptavidin-peroxidase method (S-P) was used to detect the expression of Topo Ⅱα and cyclin G1. The expression of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma tissues and adjacent normal tissues were compared. The relationship between Topo Ⅱα and cyclin G1 expression in gastric adenocarcinoma tissues and clinicopathological features were analyzed by univariate and multivariate Logistic regression. In addition, the Hp infection of gastric adenocarcinoma patients with different expressions of Topo Ⅱα and cyclin G1 was compared. Kendall tau-b correlation coefficient was used to analyze the correlation between Topo Ⅱα expression, cyclin G1 expression and Hp infection.Results:The positive rates of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma were higher than those in adjacent tissues: 60.83%(132/217) vs. 29.95%(65/217), 62.67%(136/217) vs. 0, there were statistical differences ( χ2 = 41.73, 198.07, P<0.01). There were significant differences in the positive expression rates of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma patients with different histological differentiation degrees, T stage, N stage and TNM stage ( P<0.05). The positive expression rate of Topo Ⅱα in gastric adenocarcinoma tissues with distant metastasis was significantly higher than that in gastric adenocarcinoma tissues without distant metastasis ( P<0.05). Multivariate Logistic regression analysis showed that histological differentiation degree, T stage, histological differentiation degree and N stage were the influencing factors of Topo Ⅱα expression ( P<0.05); histological differentiation degree, T stage, N stage, TNM stage were the influencing factor of cyclin G1 expression ( P<0.05). The positive rate of Hp in 217 patients with gastric adenocarcinoma was 81.57% (177/217). The positive rates of Hp in gastric adenocarcinoma patients with positive Topo Ⅱα and positive cyclin G1 were significantly higher than those with negative Topo Ⅱα and cyclin negative G1 expression: 87.12%(115/132) vs. 72.94%(62/85), 87.50% (119/136) vs. 71.60%(58/81), there were statistical differences ( χ2 = 6.92, 8.53, P<0.05). Kendall tau-b correlation coefficient analysis showed that the expression of Topo Ⅱα and cyclin G1 were positively correlated with Hp infection ( r = 0.179, 0.198, P<0.05). Conclusions:The positive rate of Topo Ⅱα and cyclin G1 in gastric adenocarcinoma is high, and it is correlated with histological differentiation, T stage, N stage and Hp infection.

Objective:To evaluate the efficacy and safety of oral semaglutide versus sitagliptin in Chinese patients with type 2 diabetes mellitus(T2DM) inadequately controlled with metformin. Methods:The PIONEER 12 study was a phase Ⅲ clinical trial. Chinese patients were prospectively randomized to oral semaglutide(3mg, 7 mg, and 14 mg) or sitagliptin 100 mg. The primary endpoint was the change in HbA 1C from baseline to week 26, and the confirmatory secondary efficacy endpoint was the change in body weight from baseline to week 26. Results:Totally 1 084 Chinese participants(mean age 53 years, male 62.2%, mean duration of diabetes 5.5 years, HbA 1C 8.2%, and body weight 74.3 kg) were enrolled. The changes in HbA 1C at week 26 from baseline were -0.9%, -1.4%, and -1.6% for oral semaglutide 3 mg, 7 mg, and 14 mg, respectively, and -0.7% for sitagliptin. Compared to sitagliptin, oral semaglutide 3 mg, 7 mg, and 14 mg significantly reduced HbA 1C [estimated treatment difference(ETD), -0.2%(95% CI -0.4--0.0), -0.8%(95% CI -0.9--0.6), and -0.9%(95% CI -1.1--0.8), respectively; 3 mg, P=0.011, 7 mg and 14mg, P<0.001]. The estimated mean changes in body weight at week 26 from baseline were -1.1 kg, -2.5 kg, and -3.4 kg for oral semaglutide 3 mg, 7 mg, and 14 mg, respectively, and -0.4 kg for sitagliptin 100 mg. Compared with sitagliptin, oral semaglutide 3 mg, 7 mg, and 14 mg significantly reduced body weight [ETD, -0.8 kg(95% CI -1.3--0.2), -2.1 kg(95% CI -2.6--1.6), and -3.0 kg(95% CI -3.5--2.5), respectively; 3 mg, P=0.004, 7 mg and 14 mg, P<0.001]. The overall incidence of adverse events was similar across all treatment groups. The most common adverse events were gastrointestinal disorders, mostly mild or moderate in severity and transient in duration. Conclusions:Oral semaglutide resulted in significantly greater reduction in HbA 1C and body weight versus sitagliptin at week 26, with a favorable safety and tolerability profile in Chinese T2DM patients inadequately controlled with metformin.
