Objective:To explore the influencing factors of left ventricular thrombus (LVT) in patients with non-ischemic heart failure (NIHF) and to construct a nomogram prediction model for NIHF patients with LVT.Methods:This study was a case-control study. A total of 2 592 patients with NIHF hospitalized in Beijing Anzhen Hospital affiliated to Capital Medical University from January 2018 to July 2022 were selected. Fifty-one patients with LVT identified by echocardiography and cardiac magnetic resonance were classified into LVT group. One hundred and sixty patients were selected as the non-LVT group using a 1∶3 propensity score matching based on age and gender. Multivariate logistic regression analysis was used to explore the influencing factors of LVT in patients with NIHF. A nomogram prediction model was constructed, and the area under (AUC) the receiver operating characteristic (ROC) curve was calculated to evaluate the predictive effect of the model.Results:A total of 211 patients were enrolled, with a median age of 40 years old and 160 males (76%). Compared with non-LVT group, LVT group had lower systolic blood pressure ((112±20) mmHg vs. (120±19) mmHg; 1 mmHg=0.133 kPa), lower left ventricular ejection fraction (LVEF; (27±12)% vs. (39±14)% ), lower proportion of patients with history of hypertension (28% (14/51) vs. 44% (70/160)) and atrial fibrillation (8% (4/51)vs.39% (62/160)), higher proportion of patients with New York Heart Association functional class Ⅲ to Ⅳ (class Ⅲ: 59% (30/51) vs. 41% (66/160); class Ⅳ: 28% (14/51) vs. 19% (31/160)), and larger left ventricular end-systolic diameter (LVESD; (56±14) mm vs. (50±15) mm). The levels of hemoglobin ((152±23) g/L vs. (142±30) g/L), D-dimer (508 (300, 1 105) μg/L vs. 158 (68, 379) μg/L), and N-terminal pro-brain natriuretic peptide (3 429 (2 462, 4 734) ng/L vs. 1 288 (422, 2 544) ng/L) were higher in LVT group than in non-LVT group ( P all<0.05). LVT group had a higher proportion of patients using beta-blockers (92% (47/51) vs. 78% (124/160)), angiotensin-converting enzyme inhibitors or angiotensin receptor blockers or angiotensin receptor neprilysin inhibitors (88% (45/51) vs. 72% (115/160)), and anticoagulant drugs (98% (50/51) vs. 32% (51/160)) than non-LVT group (all P <0.05). Multivariate logistic regression showed that reduced LVEF ( OR=1.08, 95% CI 1.02-1.15, P=0.008), decreased LVESD ( OR=1.07, 95% CI 1.01-1.12, P=0.013), and increased D-dimer levels ( OR=5.40, 95% CI 1.98-14.74, P=0.001) were independent influencing factors for LVT in patients with NIHF. The ROC curve showed that the AUC of the nomogram for predicting LVT in patients with NIHF was 0.793 (95% CI 0.710-0.876, P<0.001). Conclusion:Reduced LVEF, decreased LVESD, and elevated D-dimer are associated with LVT in NIHF patients. The predictive model developed based on the above indicators has certain value in predicting LVT in NIHF patients.

Maxillary sinus is located in the maxilla bone with the largest volume in all sinuses and is closest to the roots of maxillary posterior teeth, especially the mesiobuccal root of the maxillary second molar. The thickness of the normal maxillary sinus mucosa is about 1 mm. When stimulated or infected, it shows thickening of the mucosa. Periodontitis is one of the most common oral diseases in human beings, and the complex root anatomy of the maxillary molars aggravates the difficulty of inflammation control. Severe periodontitis of maxillary molars without effective treatment can affect the maxillary sinus, increasing the possibility of the mucosa thickening, and is also one of the reasons for the occurrence of odontogenic maxillary sinusitis (OMS). There are many different schemes for the treatment of OMS caused by severe periodontitis of maxillary molars. Extraction of teeth with severe periodontal disease without retention value or successful periodontal treatment can significantly reduce the thickness of maxillary sinus mucosa. For the patients with uncontrollable sinusitis by using drug treatment and eliminating odontogenic causes, or ones with severe symptoms, periodontal treatment and endoscopic sinus surgery can be combined to effectively control the periodontitis related maxillary sinusitis.

Objective:To explore the disease characteristics and TCM constitutions of patients with nonunion; To analyze the risk factors of nonunion and its correlation with TCM constitution; To provide research ideas for the prevention and treatment of nonunion with TCM based on the concept of "prevention of disease".Methods:This study was an observational case-control study. 334 orthopedic patients who visited the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from September 2020 to September 2022 were selected. 167 patients were collected according to the diagnostic criteria of nonunion, then 167 patients who met the criteria of fracture healing were included as the control group. General information and the classification of TCM constitutions of the patients were collected. The distribution rules of TCM constitution and patients' risk factors were statistically analyzed, and the correlation between the two was explored.Results:The unbalanced constitution was found in 126 cases (75.45%) in the bone nonunion group and 108 cases (62.87%) in the fracture healing group, with statistical significance ( χ2=4.63, P=0.032). The proportion of TCM constitutional types distributed among the patients with nonunion were in the following order: phlegm-dampness constitution, yang-deficiency constitution, mild constitution, qi-deficiency constitution, yin-deficiency constitution, damp-heat constitution, qi-stagnation constitution, blood-stasis constitution and inherited-special constitution. There was statistical significance between the nonunion group and the fracture healing group in the phlegm-dampness and yang-deficiency in men and yang-deficiency in women ( χ 2 values were 19.12, 4.96, 4.92, respectively, P<0.01 or P<0.05). Diabetes [ OR (95% CI): 2.672(1.067, 6.693), P=0.036], BMI≥24 [ OR (95% CI): 1.903 (1.182,3.063), P=0. 008], phlegm-dampness [ OR (95% CI): 3.099 (1.624,5.913), P=0.001] and yang-deficiency [ OR (95% CI): 2.424 (1.252,4.693), P=0.009] as independent risk factors for the development of nonunion in multifactorial logistic regression analysis. Conclusions:The proportion of unbalanced constitution in patients with nonunion is significantly higher than that in patients with fracture healing. Phlegm-dampness constitution and yang-deficiency constitution are independent risk factors for the development of nonunion. TCM constitutional types can be an important factor in the risk assessment of nonunion and the prevention and treatment of nonunion based on the concept of "prevention of disease" has a sound theoretical basis and wide application prospects.

Purpose: Prehabilitation (PH) is purported to improve patients’ preoperative functional status. This systematic review and meta-analysis sought to compare short-term postoperative outcomes between patients who underwent a protocolized PH program and the existing standard of care among colorectal cancer patients awaiting surgery. Methods: A search in MEDLINE/PubMed, the Cochrane Library, Embase, Scopus, and CINAHL was conducted to identify relevant articles. Repetitive and exhaustive combinations of MeSH search terms (“prehabilitation,” “colorectal cancer,” “colon cancer,” and “rectal cancer”) were used to identify randomized and nonrandomized studies comparing PH versus standard of care for colorectal cancer patients awaiting surgery. The primary outcomes included postoperative morbidity, length of hospital stay, and readmission rates. Results: Seven studies including 1,042 colorectal cancer patients (PH, 382) were included. No significant differences were found in intraoperative outcomes. The postoperative complication rates were comparable between groups (Clavien-Dindo grades I and II: risk ratio, 0.82; 95% confidence interval, 0.62–1.07; P=0.15; Clavien-Dindo grades ≥III: risk ratio, 1.02; 95% confidence interval, 0.72–1.44; P=0.92). There were also no significant differences in length of hospital stay (P=0.21) or the risk of 30-day readmission (P=0.68). Conclusion Although PH does not appear to improve short-term postoperative outcomes following colorectal cancer surgery, the quality of evidence is impaired by the limited trials and heterogeneity. Thus, further large-scale trials are warranted to draw definitive conclusions and establish the long-term effects of PH.

cFos is one of the most widely-studied genes in the field of neuroscience. Currently, there is no systematic database focusing on cFos in neuroscience. We developed a curated database-cFos-ANAB-a cFos-based web tool for exploring activated neurons and associated behaviors in rats and mice, comprising 398 brain nuclei and sub-nuclei, and five associated behaviors: pain, fear, feeding, aggression, and sexual behavior. Direct relationships among behaviors and nuclei (even cell types) under specific stimulating conditions were constructed based on cFos expression profiles extracted from original publications. Moreover, overlapping nuclei and sub-nuclei with potentially complex functions among different associated behaviors were emphasized, leading to results serving as important clues to the development of valid hypotheses for exploring as yet unknown circuits. Using the analysis function of cFos-ANAB, multi-layered pictures of networks and their relationships can quickly be explored depending on users' purposes. These features provide a useful tool and good reference for early exploration in neuroscience. The cFos-ANAB database is available at www.cfos-db.net .

Objective: To investigate the relationships of intracranial compartment volumes with the severity of clinical symptoms before surgery, and the degree of symptom improvement one year after cerebrospinal fluid(CSF)shunt surgery in patients with idiopathic normal pressure hydrocephalus(iNPH). Methods: Twenty-one patients meeting the diagnosis criteria of international guidelines of iNPH and undergoing CSF shunt surgery in Department of Neurosurgery in our hospital from 2016 to 2017 were included.All patients underwent brain MRI measurement before surgery, and were evaluated by using 3-meter timed up and go test(TUG), minimum mental state examination(MMSE), idiopathic normal pressure hydrocephalus grading scale(iNPHGS)and modified Rankin scale(mRS)before and one year after CSF shunt procedures.The ventricular volume, brain volume, pericerebral CSF volume, total intracranial volume and Evans' index were measured in the pre-operative imaging of the brain.The following four pre-operative intracranial compartment volumes were calculated: the relative ventricular volume, brain volume ratio, pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume. Results: The scores of gait, cognitive function and urinary function were improved after surgery in iNPH patients(all P<0.05). There were no significant difference in the correlation of intracranial compartment volumes(the relative ventricular volume, brain volume ratio, pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume)and Evans' index with the severity of clinical symptoms including gait, cognitive function and urinary function before surgery, and with the degree of symptom improvement one year after surgery in iNPH patients(all P>0.05). There was no significant difference in intracranial compartment volumes between patients having improvement in mRS, TUG, MMSE and iNPHGS and patients having no improvement one year after surgery in iNPH patients(all P>0.05). Conclusions Patients with iNPH can benefit from CSF shunt surgery and have improvements of clinical symptoms including gait, cognitive function and urinary function.Preoperative intracranial compartment volumes(the relative ventricular volume, brain volume ratio, pericerebral CSF volume ratio and the ratio of ventricular volume to pericerebral CSF volume)and Evans' index have no correlations with the severity of clinical symptoms before surgery, and have no correlations with the degree of symptom improvement one year after surgery in iNPH patients.For this reason, preoperative intracranial compartment volumes and Evans' index cannot be used to predict whether or not CSF shunt surgery can improve specific clinical symptoms.

Objective:To explore the value of thyroid radioactive iodine uptake (RAIU) on predicting the residual activity in patients with differentiated thyroid carcinoma (DTC) after administration of 131I. Methods:A total of 178 patients (63 males, 115 females, age: (39.8±11.4) years) with DTC who underwent initial treatment of 131I in Suzhou Science & Technology Town Hospital between August 2018 and April 2019 were enrolled in this retrospective study. RAIU test and thyroid imaging were performed before 131I treatment. Patients were divided into 3 groups according to the thyroid remnant showed by thyroid imaging: no remnant group, a little remnant group, and obvious remnant group. Radiation dose equivalent rates at different time points (immediately/24 h/48 h/72 h after injection of 131I) were measured to estimate the residual activity of 131I after administration. RAIU and residual activity at 72 h among different thyroid remnant groups were compared by one-way analysis of variance. Relationship between RAIU/ 131I therapeutic dose and residual activity at 72 h was analyzed by Pearson correlation analysis. The linear regression equation between RAIU and residual activity at 72 h after treatment was established. Results:The 3 h RAIU in no remnant group ( n=45), a little remnant group ( n=101), and obvious remnant group ( n=32) were (4.77±1.46)%, (5.53±1.70)% and (8.92±3.75)%, respectively ( F=39.35, P<0.01), and the 24 h RAIU was also significantly different among those 3 groups ((1.54±0.88)%, (3.41±2.55)%, (13.52±8.59)%; F=91.52, P<0.01). The residual activity at 72 h in no remnant group, a little remnant group, and obvious remnant group were (81.70±25.61), (108.24±51.58) and (283.07±133.72) MBq, respectively ( F=92.84, P<0.01). There was a significant positive correlation between RAIU and the residual activity at 72 h (3 h: r=0.753, 24 h: r=0.817, both P<0.01). The linear regression equations between RAIU at 3 h and 24 h and the residual activity at 72 h were y=28.88 x-38.42 and y=13.87 x+ 67.01, respectively. When RAIU was higher than 24.01% at 3 h or 15.18% at 24 h, the residual activity at 72 h after treatment was likely to exceed 400 MBq. There was little correlation between 131I therapeutic dose and the residual activity at 72 h after treatment ( r=0.119, P>0.05). Conclusion:RAIU can be used to predict the residual activity at 72 h after treatment in DTC patients who underwent initial 131I treatment.

Objective To evaluate the survival and prognostic factors of esophageal cancer treated with definitive ( chemo ) radiotherapy by applying novel radiation techniques including three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT). Methods Clinical data of 2762 patients with non-operated esophageal squamous cell carcinoma who underwent definitive ( chemo ) radiotherapy from 2002 to 2016 in 10 hospitals were retrospectively analyzed.The prognostic factors were also identified and analyzed. Results The median follow-up time was 60. 8 months. The 1-, 2-, 3-and 5-year overall survival (OS) of all patients was 71. 4％,48. 9％,39. 3％,and 30. 9％,respectively.The 1-,2-,3-and 5-year progression-free survival (PFS) was 59.5％,41.5％,35.2％,and 30％,respectively.The median survival was 23 months.The median time to progression was 17. 2 months.Multivariate analysis demonstrated that age, primary tumor location, clinical stage, tumor target volume, EQD2 and treatment mode were the independent prognostic factors for OS.Primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS. Conclusions In this first large-scale multi-center retrospective analysis of definitive ( chemo) radiotherapy for esophageal squamous cell carcinoma in China, the 5-year OS of patients with esophageal squamous cell carcinoma is significantly improved by 3DCRT, IMRT combined with chemotherapy drugs. However, the findings remain to be validated by prospective clinical trials with high-level medical evidence.
