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.

This study aims to explore the factors influencing the success rate of the microdissection testicular sperm extraction (Micro-TESE) in patients with nonobstructive azoospermia (NOA) and cryptorchidism. Clinical data of 162 patients with cryptorchidism who underwent Micro-TESE due to infertility from December 2015 to May 2020 in the First Affiliated Hospital of Nanjing Medical University were analyzed retrospectively. In the univariate analysis, significant differences in the age of patient at the time of orchidopexy (median [interquartile range, IQR]: 7.0 [4.0-11.0] years vs 11.5 [9.0-14.5] years, P < 0.001), interval between orchidopexy and Micro-TESE (mean ± standard deviation: 17.5 ± 5.0 years vs 14.4 ± 4.4 years, P < 0.001), severity of cryptorchidism (unilateral [62.8%] vs bilateral [31.6%], P < 0.001; location of cryptorchidism, intra-abdominal [27.3%] vs inguinal [44.8%] vs suprascrotal [66.7%], P < 0.001), volume of the dominant testis (median [IQR]: 17.00 [15.00-19.00] ml vs 14.50 [11.75-16.25] ml, P < 0.001), and levels of follicle-stimulating hormone (FSH; P = 0.004) and testosterone (P = 0.006) were observed between the successful and failed sperm extraction groups. After conducting the multivariate analysis, four of these factors, including unilateral/bilateral cryptorchidism (P < 0.001), location of cryptorchidism (P = 0.032), age of orchidopexy (P < 0.001), and dominant testicular volume, were adopted in the clinical prediction model to evaluate preoperatively the success rate of Micro-TESE for patients with NOA and cryptorchidism. The likelihood of successful sperm retrieval by Micro-TESE in men with NOA and cryptorchidism increased in patients with mild forms of cryptorchidism.

Sulforaphane (SFN), a natural anti-tumor compound from cruciferous vegetables, has been reported to induce protective autophagy to cancer cells, which might impair the anti-tumor efficiency of SFN. However, the accurate function and mechanism of SFN inducing autophagy in cancers are still obscure, especially in esophageal squamous cell carcinoma (ESCC), one of malignancies with high incidence in North China. Here, we mainly explored the potential function of autophagy upon SFN treatment in ESCC and molecular mechanism. We demonstrated that SFN could inhibit cell proliferation and induce apoptosis by activating caspase pathway. Moreover, we found activation of NRF2 pathway by SFN was responsible for the induction of autophagy and also a disadvantage element to the anti-tumor effects of SFN on ESCC, indicating that SFN might induce protective autophagy in ESCC. We, therefore, investigated effects of autophagy inhibition on sensitivity of ESCC cells to SFN and found that chloroquine (CQ) could neutralize the activation of SFN on NRF2 and enhance the activation of SFN on caspase pathway, thus improved the anti-tumor efficiency of SFN on ESCC

Objective To explore chromobox protein homolog 2 (CBX2) expressions in relation to clinical features of patients and elucidate its role in the progression of hepatocellular carcinoma.Methods Using the Cancer Genome Atlas (TCGA) database,R language was used to analyze the distribution of differentially expressed mRNA in hepatocellular carcinoma.The different expression of CBX2 in HCC and adjacent tissues and its relationship with survival and clinical characteristics of patients were further analyzed.The expression of CBX2 in liver tissues,liver cancer tissue,and L02,HepG2 and SMMC-7721 cell lines was detected by real time-PCR and western blot.The expression of CBX2 was interfered by siRNA in hepatoma cell line.MTT,colony formation,transwell assays,and flow cytometry were used to identify the proliferation,apoptosis,invasion and clone-formation ability of HepG2 and SMMC-7721 cells after CBX2 down-regulation.According to the different data,t-test,ANOVA,chi-square test,and COX regression model were used for statistical analysis.Survival curve was plotted through Kaplan-Meier method.Results TCGA public database analysis showed that the expression of CBX2 mRNA in hepatocellular carcinoma tissues (7.296 ± 1.6115) was significantly higher than normal liver tissues (4.706 ± 0.940) (P =0.000).In addition,the overall survival time of patients with low CBX2 mRNA expression was significantly longer than that of patients with high CBX2 mRNA expression [(5.971 ± 0.411) years vs.(4.650 ± 0.503) years,P =0.001].The expression level of CBX2 mRNA was correlated with the pathological TNM stage (P =0.025) and differentiation degree (P ＜ 0.001) of liver cancer.COX regression analysis showed that CBX2 mRNA expression was an independent predictor of patient survival (P =0.013).siRNA was transfected and compared with the blank control group.The transgenic ability of HepG2 and SMMC-77221 cells decreased significantly at 72h (P ＜ 0.05) and 96h (P ＜ 0.05),and the apoptosis rate (11.430％ ± 0.215％) was higher than blank control group (6.6 00％ ± 0.170％) (P =0.003).The number of invasive cells ((both P ＜ 0.05) and relative colony forming cells ((both P ＜ 0.001) were significantly decreased.In 20 cases of tissue samples,the expression of CBX2 protein (relative expression level 3.020 ±0.269) in liver cancer was higher than that in adjacent tissues (relative expression level 0.886±0.065) (P ＜ 0.001).The overall survival time of patients with low CBX2 expression in liver cancer was longer than that of patients with high expression [(3.670 + 0.576) years vs.(0.834 + 0.153) years,P =0.004].Conclusion An evident high expression of CBX2 is an independent poor prognostic factor in hepatoma.Down-regulation of CBX2 expression can inhibit the progression of liver cancer.Therefore,CBX2 may be a prognostic biomarker and a new target for HCC treatment.

To establish a genetic susceptibility assessment model of lung cancer risk potentially associated with polycyclic aromatic hydrocarbon (PAH) inhalation exposure among non-smokers in China, a total of 143 patients with lung adenocarcinoma and 143 cancer-free individuals were recruited. Sixty-eight genetic polymorphisms in 10 pathways related to PAH metabolism and tumorigenesis were selected and examined. It was observed that 3 genetic polymorphisms, along with 10 additional genetic polymorphisms via gene-gene interactions, significantly influenced lung cancer risk potentially associated with PAH inhalation exposure. Most polymorphisms were associated with PAH metabolism. According to the established genetic susceptibility score (GSS), lung cancer risk increased with a rise in the GSS level, thereby indicating a positive dose-response relationship.
