Objective To investigate the influencing factors associated with the comorbidity of inflammatory bowel disease (IBD) and depression. Methods A case-control study was conducted based on the ^“Healthcare Big Data Platform^” of a tertiary class-A comprehensive hospital in Shandong Province. IBD comorbid with depression was served as the case group and IBD without depression was served as the control group. Propensity score matching (PSM) was performed by matching the case group with the control group in a ratio of 1:2 according to the age and gender of the patients. Conditional logistic regression model was used to explore the influencing factors associated with the comorbidity of IBD and depression. Results A total of 405 patients with IBD were enrolled in this study, including 270 patients without depression and 135 patients comorbid with depression. The results of conditional logistic regression showed that the use of immunosuppressants (OR=2.84, 95% CI: 1.00-8.07) and glucocorticoids (OR=2.05, 95% CI: 1.17-3.58), dementia (OR=5.20, 95% CI:1.59-17.05), cardiovascular disease (OR=3.58, 95% CI: 1.84-6.98) and cancer (OR=2.63, 95% CI: 1.16-5.95) were associated with the comorbidity of depression and IBD. Conclusion Attention should be paid to the use of immunosuppressants and glucocorticoids in the population of IBD comorbid with depression, and the coexistence of physical diseases such as dementia, cardiovascular disease and cancer. Early prevention and targeted treatment measures should be taken for high-risk populations to reduce their risk of depression and improve their quality of life and health.

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.

Traumatic brain injury (TBI), as a significant central nervous system damage disease with high frequency in the world, leads to a huge number of patients with impaired health and lower quality of life every year. Lung injury is a common and dangerous consequence, which dramatically raises the mortality of patients. Discovering the pathophysiology of lung injury after TBI and discovering viable therapeutic targets has become an important need for clinical diagnosis and therapy. Neurotransmitters, as the fundamental chemical agents of the nervous system for signal transmission, not only govern neuronal activity and apoptosis in TBI but also significantly influence the pathophysiological mechanisms of lung injury subsequent to TBI. The imbalance is intricately linked to the onset and progression of lung damage. This paper systematically reviews the clinical characteristics and predominant pathogenesis of lung injury following TBI, emphasizing the role of key neurotransmitters, including glutamate (Glu), γ-aminobutyric acid (GABA), norepinephrine (NE), dopamine (DA), and acetylcholine (ACh), in lung injury post-TBI. It examines their influence on inflammatory response, vascular permeability, and pulmonary circulation function. Additionally, the paper evaluates the research advancements and potential applications of targeted therapeutic strategies for various neurotransmitter systems, such as receptor antagonists, transporter inhibitors, and neurotransmitter analogues. This research aims to offer a theoretical framework for clarifying the neural regulatory mechanisms of lung injury following TBI and to establish a basis for the development of novel therapeutic strategies and enhancement of the prognosis of the patients.

Diabetic peripheral neuropathy(DPN)is a common and devastating complication of diabetes,for which effective therapies are currently lacking.Disturbed energy status plays a crucial role in DPN pathogenesis.However,the integrated profile of energy metabolism,especially the central carbohy-drate metabolism,remains unclear in DPN.Here,we developed a metabolomics approach by targeting 56 metabolites using high-performance ion chromatography-tandem mass spectrometry(HPIC-MS/MS)to illustrate the integrative characteristics of central carbohydrate metabolism in patients with DPN and streptozotocin-induced DPN rats.Furthermore,JinMaiTong(JMT),a traditional Chinese medicine(TCM)formula,was found to be effective for DPN,improving the peripheral neurological function and alleviating the neuropathology of DPN rats even after demyelination and axonal degeneration.JMT ameliorated DPN by regulating the aberrant energy balance and mitochondrial functions,including excessive glycolysis restoration,tricarboxylic acid cycle improvement,and increased adenosine triphosphate(ATP)generation.Bioenergetic profile was aberrant in cultured rat Schwann cells under high-glucose conditions,which was remarkably corrected by JMT treatment.In-vivo and in-vitro studies revealed that these effects of JMT were mainly attributed to the activation of adenosine monophosphate(AMP)-activated protein kinase(AMPK)and downstream peroxisome proliferator-activated receptor gamma coactivator 1-alpha(PGC-1α).Our results expand the thera-peutic framework for DPN and suggest the integrative modulation of energy metabolism using TCMs,such as JMT,as an effective strategy for its treatment.

Objective　To investigate the relationship between exosomal microRNA (miR)-335-5p and the severity of cirrhosis in patients with chronic hepatitis B (CHB), in order to provide more clinical information for early intervention and treatment. Methods From February to August 2019, 6 healthy controls, 8 cases of compensated cirrhosis (CLC), and 8 cases of decompensated cirrhosis (DLC) were recruited from the physical examination outpatient department and the hepatology department of Peking University Third Hospital Qinhuangdao Hospital as a discovery cohort, and serum samples were collected for exosome extraction and miRNA microarray analysis. A validation cohort of 229 CHB patients with cirrhosis, including 94 CLC and 135 DLC patients, was selected from those diagnosed and treated in the hepatology department of the hospital from December 2019 to May 2022. Exosomes were extracted and identified, and the expression level of serum exosomal miR-335-5p was detected by real-time fluorescence quantitative PCR. The model for end-stage liver disease (MELD) score and the combined formula of serum sodium with MELD (MELD-Na) score were used to evaluate the severity of cirrhosis. Results In the discovery cohort, the expression of miR-335-5p in the DLC group was significantly down-regulated compared to the control group and CLC group (P<0.05). In the validation cohort, the level of exosomal miR-335-5p in the DLC group was significantly lower than that in the CLC group (P<0.001). Spearman correlation analysis showed a negative correlation between the expression of exosomal miR-335-5p and both MELD and MELD-Na scores in patients with cirrhosis (P<0.05). After adjusting for other confounding factors in the multiple linear regression model, the expression of exosomal miR-335-5p was still negatively correlated with MELD score (β=-0.103, 95%CI:-3.692 to -1.149, P<0.001) and MELD-NA score (β=-0.109, 95%CI:-4.007 to -1.270, P<0.001). ROC curve analysis indicated that serum exosomal miR-335-5p could differentiate DLC with an area under the ROC curve of 0.905 (95%CI: 0.867 to 0.944), corresponding to a cutoff value of 0.158, with a specificity of 87.2%, and a sensitivity of 83.7%. Conclusions The low expression of exosomal miR-335-5p is associated with the aggravation of cirrhosis in CHB patients, and may serve as a useful biomarker for the early diagnosis of DLC.

This study was aimed at identifying the bioactive components of the crude and stir-baked hawthorn for invigorating spleen and promoting digestion, respectively, to clarify the processing mechanism of hawthorn by applying the partial least squares(PLS) algorithm to build the spectrum-effect relationship model. Firstly, different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions were prepared, respectively. Then, the contents of 24 chemical components were determined by ultra-high performance liquid chromatography-mass spectrometry. The effects of different polar fractions of crude hawthorn and stir-baked hawthorn aqueous extracts and combinations of different fractions were evaluated by measuring the gastric emptying rate and small intestinal propulsion rate. Finally, the PLS algorithm was used to establish the spectrum-effect relationship model. The results showed that there were significant differences in the contents of 24 chemical components for different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions, and the gastric emptying rate and small intestinal propulsion rate of model rats were improved by administration of different polar fractions of crude and stir-baked hawthorn aqueous extracts and combinations of different fractions. The bioactive components of crude hawthorn identified by PLS models were vitexin-4″-O-glucoside, vitexin-2″-O-rhamnoside, neochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, malic acid, quinic acid and fumaric acid, while neochlorogenic acid, cryptochlorogenic acid, rutin, gallic acid, vanillic acid, citric acid, quinic acid and fumaric acid were the bioactive components of stir-baked hawthorn. This study provided data support and scientific basis for identifying the bioactive components of crude and stir-baked hawthorn, and clarifying the processing mechanism of hawthorn.
