ABSTRACT

@#Glaucoma is a group of diseases characterized by progressive optic nerve atrophy and visual field defects. Some evidence demonstrate that glaucoma's pathological damage affects the retina and optic nerve and involves the entire visual pathway. Recent studies have found that the nerve injury is not completely irreversible but has certain plasticity. Furthermore, studies have shown that neurons in the visual pathway of glaucoma can be repaired and remodeled under certain conditions to restore visual function, which offers a new way to treat glaucoma.

ABSTRACT

BACKGROUND@#There is limited evidence of the effects of local anesthesia (LA) on outcomes of non-surgical periodontal treatment (NSPT), in particular among the Chinese. This retrospective cohort study aimed to evaluate the effects of LA on short-term treatment outcomes of NSPT and to determine under what circumstances LA should be prescribed to improve these outcomes.@*METHODS@#Data from periodontal examinations of 3980 patients were used. The data were from 3-month re-evaluation records of an electronic periodontal charting record system in the Department of Periodontology of Peking University School and Hospital of Stomatology from June 2008 to January 2015. Descriptive analyses included changes in probing depth (PD) and the Mazza bleeding index (BI). Two-level (patient and tooth) logistic regression models and three-level (patient, tooth, and site) linear regression models were constructed to analyze the influence of LA on PD for all teeth/sites and teeth/sites with an initial PD ≥ 5 mm. Decreases in PD and BI at sites under LA using the initial PD were also compared.@*RESULTS@#A significantly higher mean decrease in PD after NSPT was found in the LA group than in the no local anesthesia (NLA) group (0.98 vs. 0.54 mm, t = 24.12, P  1 and BI > 2) for all teeth (16.7% vs. 13.8%, t = 3.75, P < 0.001; 34.7% vs. 28.1%, t = 6.73, P < 0.001) and PD for teeth with PD ≥ 5 mm (32.3% vs. 17.3%, t = 28.48, P < 0.001). The difference in PD between the LA and NLA groups increased as the initial PD increased. The difference between the two groups was 0.12 to 0.22 mm for sites with a baseline PD < 7 mm; however, it increased to 0.41 to 1.37 mm for sites with a baseline PD ≥ 7 mm.@*CONCLUSIONS@#LA improved the decrease in PD after NSPT. Root debridement at sites with initial PD ≥ 7 mm should be performed under routine LA.

ABSTRACT

Dyspnea is one of the most common manifestations of patients with pulmonary disease, myocardial dysfunction, and neuromuscular disorder, among other conditions. Identifying the causes of dyspnea in clinical practice, especially for the general practitioner, remains a challenge. This pilot study aimed to develop a computer-aided tool for improving the efficiency of differential diagnosis. The disease set with dyspnea as the chief complaint was established on the basis of clinical experience and epidemiological data. Differential diagnosis approaches were established and optimized by clinical experts. The artificial intelligence (AI) diagnosis model was constructed according to the dynamic uncertain causality graph knowledge-based editor. Twenty-eight diseases and syndromes were included in the disease set. The model contained 132 variables of symptoms, signs, and serological and imaging parameters. Medical records from the electronic hospital records of Suining Central Hospital were randomly selected. A total of 202 discharged patients with dyspnea as the chief complaint were included for verification, in which the diagnoses of 195 cases were coincident with the record certified as correct. The overall diagnostic accuracy rate of the model was 96.5%. In conclusion, the diagnostic accuracy of the AI model is promising and may compensate for the limitation of medical experience.

ABSTRACT

Age-associated changes in immune cells have been linked to an increased risk for infection. However, a global and detailed characterization of the changes that human circulating immune cells undergo with age is lacking. Here, we combined scRNA-seq, mass cytometry and scATAC-seq to compare immune cell types in peripheral blood collected from young and old subjects and patients with COVID-19. We found that the immune cell landscape was reprogrammed with age and was characterized by T cell polarization from naive and memory cells to effector, cytotoxic, exhausted and regulatory cells, along with increased late natural killer cells, age-associated B cells, inflammatory monocytes and age-associated dendritic cells. In addition, the expression of genes, which were implicated in coronavirus susceptibility, was upregulated in a cell subtype-specific manner with age. Notably, COVID-19 promoted age-induced immune cell polarization and gene expression related to inflammation and cellular senescence. Therefore, these findings suggest that a dysregulated immune system and increased gene expression associated with SARS-CoV-2 susceptibility may at least partially account for COVID-19 vulnerability in the elderly.

ABSTRACT

Objective: To discuss the clinical and pathological features of double primary cancer (DPC) in the stomach and colorectum. Methods: The data of 50 patients who were diagnosed with DPC and underwent surgery at The Affiliated Tumor Hospital of Xinjiang Medical University between June 2015 and June 2018 were retrospectively analyzed. The data that were analyzed included the age of onset, gender ratio, tumor stage, pathological type, and other characteristics. Thirty patients had synchronous DPC (SC), and 20 had metachronous DPC (MC). Statistical analysis was performed in the two groups. Results: The mean age was (65.44±11.94) years with 37 men and 13 women. The ratio of men to women was 2.85:1. The tumor-node-metastasis (TNM) stages were mainly stagesⅡ-Ⅲ(47/50, 94.0%). The pathological pattern was mainly adenocarcinoma (35/50, 70.0%). There was no significant difference in the pathological type, differentiation degree, and tumor stage between the first and second primary cancers in patients with MC (P<0.05). The age of patients diagnosed with SC was older than that of patients diagnosed with MC [(68.87±8.83) years vs. (60.30±14.22) years] (P=0.011). SC and MC showed no differences in gender, TNM stage, pathological type, differentiation degree, and smoking and alcohol consumption status. Conclusions: Screening for second primary cancer should be strengthened over the age of 50 years for patients with gastric cancer or colorectal cancer.

ABSTRACT

@#Glaucoma is a leading cause of irreversible blindness, which is characterized by characteristic optic atrophy and visual field defects. Elevated intraocular pressure(IOP)is a primary risk factor of glaucoma, while the main cause of elevated IOP lies in the increased aqueous outflow resistance in pathological trabecular meshwork(TM), which is the conventional outflow pathway of aqueous humor. Rho-associated protein kinase inhibitor(ROCKi)is the IOP-lowering drug that is directly acting on the TM. The TM cell morphology, cell movement, cytokinesis and cell contraction by alteration of cytoskeleton can be changed by ROCKi to increase aqueous humor outflow facility and decrease IOP. ROCKi is now approved for clinical use in the United States and Japan. Meanwhile, it might play a role in optic nerve protection through increasing retinal vascular perfusion and promoting optic nerve regeneration. In addition, it decreases the possibility of filtration bleb scarring. Therefore, ROCKi has become a new pharmacological option to treat glaucoma. This article reviews the Rho-Rho kinase signaling pathway, the mechanism of ROCKi and its clinical application.

ABSTRACT

Objective To investigate the association between gasification and duration and power of radiofrequency ablation in porcine muscle and liver and compare the effects in these tissues in an in vitro study. Methods Radiofrequency ablation was performed on fresh muscle and liver tissue,and the maximum cross-sectional volume of gasification was used to compare the effects according to duration and power of ablation. The experiment was repeated three times,and data were averaged. Results Within a certain range,gasification volume increased significantly with increases in ablation duration and power (P < 0.05). Gasification volumes differed significantly between tissues (P < 0.05). The gasification volume was smaller in muscle than in liver at 15 W and 30 W,while the affected volume in muscle was greater than in liver at 45 W (P < 0.05). Conclusion Under conditions of the same duration and power,the gasification volumes were different in muscle and liver. Therefore,the power and time required for maximum gasification in different tissues may be different.

ABSTRACT

Objective To observe the current status of secondary prevention medication usage and their relation with on-treatment platelet reactivity in patients with Acute Coronary Syndrome(ACS) treated with aspirin and clopidogrel. Methods A total of 176 patients hospitalized from 2014 to 2015 due to ACS in the Department of Cardiology, Peking University People's Hospital were enrolled and on-treatment platelet reactivity was tested by thromboelastography(TEG)and CYP2C19*2,*3 and*17 alleles were analysed. Details of secondary prevention medication and patients' clinical characteristics were recorded. The relation of secondary prevention medication and on-treatment platelet reactivity was analyzed by multi-logistic regression after adjusting for CYP2C19 alleles and clinical characteristics covariates.Results A 94.89% of patients was treated with statins while 80.68% with beta blocker. The platelet inhibition rate were (45.33±28.78)% and the high on-treatment platelet reactivity (HTPR) rate tested by TEG was 37.50%. In the multivariate logistic regression analysis, usage of β-blockers during hospitalization as well as phenotypes of CYP2C19*2,*3 and *17,clinical presentation with ST-segment elevation myocardial infarction and the length of stents were associated with HTPR defi ned by TEG. The percentage of HTPR rate was signifi cantly lower in patients treated with than those without β-blockers (72.73% vs. 85.45%,OR 0.18,95%CI 0.06-0.53,P=0.002)after adjusting genetic factors and other covariates.Conclusions There was a signifi cant correlation between beta blockers usage and high clopidogrel on-treatment platelet reactivity.
