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.

Hepatic encephalopathy is a clinical syndrome of central nervous system dysfunction caused by liver insufficiency.It severely affects the quality of life of patients and may lead to death.Accurate prediction of the risk of developing hepatic encephalopathy is crucial for early intervention and treatment.In order to identify the risk of hepatic encephalopathy in patients in advance,many studies have been devoted to efforts to develop tools and methods to identify the risk of hepatic encephalopathy as early as possible,so as to develop preventive and early management strategies.Most conventional hepatic encephalopathy risk prediction models currently assess the prob-ability of a patient developing hepatic encephalopathy by analysing factors such as clinical data and biochemical indicators,however,their accuracy,sensitivity and positive predictive value are not high.The application of artificial intelligence to clinical predictive modelling is a very hot and promising area,which can use large amounts of data and complex algorithms to improve the accuracy and efficiency of diagnosis and prognosis.To date,there have been few studies using AI techniques to predict hepatic encephalopathy.Therefore,this paper reviews the research progress of hepatic encephalopathy risk prediction models,and also discusses the prospect of AI application in hepatic encephalopathy risk prediction models.It also points out the challenges and future research directions of AI in HE risk prediction model research in order to promote the development and clinical application of hepatic encephalopathy risk prediction models.

Objective To isolate the secondary metabolites of endophytic fungus Aspergillus sp. J218 from Anectochilus roxburhii. Methods Different chromatographic methods, including Sephadex LH-20 and silica gel chromatography as well as HPLC, were used to isolate compounds from the EtOAc fraction of the solid fermentation of J218, and their structures were identified by spectral methods. Results Ten compounds were isolated from the fermentation of J218 and their structures were individually identified as kotanin（1）, flavasperone（2）, aurasperone B（3）, fonsecinone B（4）, fonsecinone D（5）, ensidol A（6）, fonsecinone A（7）, fonsecinone C（8）, aurasperone A（9）, and fonsecinone F（10）. Conclusion Most compounds isolated from endophytic fungus Aspergillus sp. J218 in Anectochilus roxburhii were identified as dimeric naphthopyrones. These results suggest that this strain contains rich dimerization synthase, which could provide clues for the further exploration of the rational biosynthesis pathway of dimeric naphthopyrones in this strain.

Introduction: COVID-19 pandemic has impacted the livelihood of Malaysians and gardening activities have contributed positively to the diet quality. This study aimed to determine the factors associated with diet quality among adults in AU2 Keramat, Kuala Lumpur. Methods: The cross-sectional study involved adults aged 18 to 59 via convenience sampling. The socio-demographic, physical activity level and involvement status in gardening were obtained through a questionnaire, while food intake was from a single-day 24-hour diet recall. The diet quality was determined through Malaysian Healthy Eating Index (MHEI) and dietary misreporting was calculated using the Goldberg cut-off method. Results: A total of 117 respondents (65.8% females, 35.2% males) with a mean age of 40.98 were involved in this study. Findings showed that most respondents did not engage in gardening activities (72.6%) and the prevalence of poor diet quality in this study was 89.7%, with a mean score of 44.51. The older respondents (r= 0.20, p= 0.034) and community gardeners (t= -2.63, p= 0.011) had a significantly higher diet quality but not home gardeners (t= 0.12, p= 0.902). The respondents involved in gardening activity also had a significantly higher fruit serving intake, Mann-Whitney U= 1045.00, p= 0.036) and lower total fat intake (t= 2.27, p= 0.025). Conclusion: The diet quality of the respondents remains poor but community gardeners had significantly higher diet quality and fruit intake while lower total fat intake. Interventions need to be developed to address the persistent poor diet quality of adults in the community.

As one of the hallmarks of cancer, metabolic reprogramming leads to cancer progression, and targeting glycolytic enzymes could be useful strategies for cancer therapy. By screening a small molecule library consisting of 1320 FDA-approved drugs, we found that penfluridol, an antipsychotic drug used to treat schizophrenia, could inhibit glycolysis and induce apoptosis in esophageal squamous cell carcinoma (ESCC). Gene profiling and Ingenuity Pathway Analysis suggested the important role of AMPK in action mechanism of penfluridol. By using drug affinity responsive target stability (DARTS) technology and proteomics, we identified phosphofructokinase, liver type (PFKL), a key enzyme in glycolysis, as a direct target of penfluridol. Penfluridol could not exhibit its anticancer property in PFKL-deficient cancer cells, illustrating that PFKL is essential for the bioactivity of penfluridol. High PFKL expression is correlated with advanced stages and poor survival of ESCC patients, and silencing of PFKL significantly suppressed tumor growth. Mechanistically, direct binding of penfluridol and PFKL inhibits glucose consumption, lactate and ATP production, leads to nuclear translocation of FOXO3a and subsequent transcriptional activation of BIM in an AMPK-dependent manner. Taken together, PFKL is a potential prognostic biomarker and therapeutic target in ESCC, and penfluridol may be a new therapeutic option for management of this lethal disease.

Objective:To investigate the effect of different chemotherapy drugs combined with DNA methylase inhibitor 5-Aza-2'-deoxycytidine (5-Aza-dC) on the apoptosis of lung adenocarcinoma cells.Methods:In the prospective randomized controlled study, lung adenocarcinoma A549 cells were treated with cisplatin plus paclitaxel (TP) or gemcitabine (GP) with or without 5-Aza-dC. According to different drug intervention methods, they were divided into control group, cisplatin combined with paclitaxel (TP) group, cisplatin combined with gemcitabine (GP) group, and 5-Aza-dC combined with TP group, 5-Aza-dC combined with GP group. CCK-8 assay was used to detect the proliferation of A549 cells. Transwell migration and invasion assay were used to detect the effect that each group of drugs on the migration and invasion ability of A549 cells. Quantitative Real-time Polymerase Chain Reaction was used to evaluate the effect of each treatment on the expression of apoptotic genes. One-way analysis of variance was used to compare the degree of cell proliferation in different drug treatment groups, and LSD- t method was used for pairwise comparison within groups. Results:The inhibition rates of lung adenocarcinoma cells in the TP regimen at different time points at 24, 48, and 72 h were as follows (20.00±4.23) %, (35.00±2.80) %, and (56.00±3.11) %. The inhibition rate of 5-Aza-dC combined with TP regimen on lung adenocarcinoma cells was significantly increased, at different time points of 24, 48 and 72 h, respectively (38.00±3.80) %, (50.00±3.25) %, (93.00±4.33) %. The inhibition rates of cells at different time points at 24, 48, and 72 h in the GP regimen were (33.00±5.10) %, (54.00±3.80) %, and (74.00±2.82) %, respectively; while 5-Aza-dC combined with GP regimen could significantly reduce the rate of cell growth, the inhibition rates of cells at 24, 48, and 72 h different time points were as follows (54.00±3.00) %, (67.00±5.30) %, and (95.00±1.13) %. The inhibitory effect of the same drug on lung adenocarcinoma cells increased with time (TP group: F=35.93, P<0.001; 5-Aza-dC combined with TP group: F=97.33, P<0.001; GP group: F =41.73, P<0.001; 5-Aza-dC combined with GP group: F=79.00, P<0.001), and at different time points, the differences were statistically different (all P<0.05). 5-Aza-dC combined with TP and GP chemotherapy regimens can inhibit the migration and invasion of lung adenocarcinoma cell A549, and the inhibitory effect is stronger than that of TP or GP regimens alone. The expression of Caspase 8 was significantly elevated ( t=5.87, P=0.004) in cells treated with 5-Aza-dC combined with GP when compared with GP regimen alone. The expression of Caspase 8 ( t=3.94, P=0.017), Caspase 6 ( t=5.81, P=0.004) and BBC3 (BCL-2 binding component 3) ( t=6.53, P=0.003) were increased when drugged with 5-Aza-dC combined TP regimen compared with TP regimen alone. Conclusion:5-Aza-dC might serve as a chemotherapeutic sensitizer to increase the sensitivity of lung adenocarcinoma cells.

Objective:To compare the efficacy and safety of providing nasogastric (NG), nasojejunal (NJ), and parenteral nutrition (PN) support to pancreatitis patients who were intolerant to oral feeding.Methods:One hundred pancreatitis patients who were intolerant to oral feeding treated at the Xuanwu Hospital of the Capital Medical University from October 2018 to September 2020 were retrospectively studied. They were divided into three groups based on the nutritional support given to them: the NG group, NJ group, and PN group. The acute physiology and chronic health evaluation Ⅱ(APACHEⅡ), nutritional risk screening 2002 (NRS2002), hemoglobin, albumin, pre-albumin and other clinical data were recorded and compared among the three groups.Results:After nutrition support treatments, the hemoglobin, albumin and pre-albumin levels were significantly better than before giving nutrition support, and the APACHE Ⅱ scores were significantly improved in all the groups. The NRS2002 scores were significantly better in the NJ group ( Z=2.28, P=0.023) and the NG group ( Z=1.99, P=0.046). With compared to the PN group, the albumin and pre-albumin levels were significantly higher in the NG and NJ groups, and the NRS2002 score after giving nutrition support treatment was significantly lower ( P<0.05). Compared with the PN group, the APACHE Ⅱ score ( t=2.18) and the hemoglobin levels ( t=2.04) were significantly better in the NJ group ( P<0.05). The overall incidence of complications in the NJ group was 41.2% (14/34), which was significantly lower than the NG group [78.8%(26/33), χ 2=5.41, P=0.020] and the PN group [66.7% (22/33), χ 2=4.35, P=0.037]. Conclusion:Enteral nutrition support through NG and NJ are better than PN in acute pancreatitis patients who were intolerant to oral feeding.

Objective:To observe the effects of continuous light exposure on skeletal muscle fiber type transformation and lipid metabolism, and to explore its internal relationship.Methods:Mice were randomly divided into normal light group and 24-hour continuous light group by random number table. The serum and skeletal muscle lipid content and urine 6-sulfatoxymelatonin(6-SML)level were detected by ELISA. The expression of circadian clock and lipid metabolism related genes mRNA were observed by realtime PCR. The muscle fiber type and lipid deposition were evaluated by tissue immunofluorescence as well as oil red O staining.Results:Compared with the normal light group, the level of 6-SML in urine at night decreased( P<0.05), and the expression level and rhythm of brain and muscle ARNT-like protein 1(Bmal1), circadian locomotor output cycles protein kaput(Clock), and period 2(Per2)mRNA in the skeletal muscle changed in continuous light group. In addition, the body weight, blood lipid, free fatty acid, and triglyceride contents of skeletal muscle in continuous light group increased significantly( P<0.05 or P<0.01), the expression of carnitine palmitoyltransferase 1b (Cpt1b)mRNA, the key enzyme of fatty acid oxidation, decreased significantly( P<0.05), while the expression of stearoyl-CoA desaturase(Scd1)mRNA, a lipid synthesis related gene, increased significantly( P<0.01). Further immunofluorescence analysis showed that the proportion of slow muscle fibers decreased and that of fast muscle fibers increased in continuous light group(both P<0.05). Conclusion:The process of ectopic deposition of lipid in skeletal muscle in mice induced by continuous light exposure may be related to the remodeling of skeletal muscle fibers.
