Objective To analyze the clinical and laboratory characteristics of the ischemic stroke in patients with non-valvular atrial fibrillation (AF), and to provide evidence for the prevention of ischemic stroke. Methods A total of 198 patients with ischemic stroke were chosen and divided into two groups:with AF (71 patients)/and without AF (127 patients) groups. Clinical data and biochemical markers were collected and compared in two groups. CHADS2 and CHA2DS2-VASc score systems were used to determine the risk levels in patients with AF. Finally, related risk factors of ischemic stroke with AF were determined and analyzed. Results The values of age, length of hospital stay, the hypertention history, heart rate and plasma homocysteine (Hcy) were significantly higher in the with-AF group than those in the without-AF group ( P <0.05). The levels of total cholesterol (TC), triglyceride (TG) and very low density lipoprotein cholesterol (VLDL-C) were sig?nificantly lower in the with-AF group than those of the without-AF group (P<0.05). CHA2DS2-VASc scores reached to the moderate-to-high risk level in the with-AF group. Multiple-factor logistic regression analysis showed that age and heart rate were the independent risk factors of the ischemic stroke in patients with non-valvular AF. ROC analysis indicated that age (AUC=0.761, cut-off point=72.50 years old) and heart rate (AUC=0.612, cut-off point=76.50 bit/min) had predictive and di?agnostic value for the ischemic stroke in patients with non-valvular AF. The age of these patients had the best sensitivity (70.4%) and specifity (71.1%), and the cut-off point of which was 72.50 years old. Conclusion The characteristics of isch?emic stroke in patients with non-valvular AF includes older age, faster heart rate, higher CHA2DS2-VASc scores and higher Hcy level.

Objective:To analyze the effects of the primary location of colorectal cancer on the surgical outcome of liver metastases.Methods:A cross-sectional study was conducted on 178 patients with liver metastases from colorectal cancer admitted to Binzhou Central Hospital from January 2012 to January 2022. According to whether the patients had recurrence after surgery, they were divided into a recurrence group ( n = 88) and a control group ( n = 90). The general and clinical data were compared between the two groups. Logistic multivariate analysis of the factors with statistical significance was further performed to identify the risk factors of postoperative recurrence of liver metastases from colorectal cancer after surgery. The correlation between the primary location of colorectal cancer and each risk factor was analyzed. The recurrence of colorectal cancer was compared anong patients with different primary locations of colorectal cancer at 12 months after surgery. Results:Primary location at the right colon [55.68% (49/88), lymph node metastasis [92.05% (81/88)], D-dimer ≥ 180 μ g/L, albumin < 29 g/L, ineffective/no neoadjuvant chemotherapy [43.18% (33/38)], and high-risk clinical risk score [53.41% (47/88)] were risk factors for postoperative recurrence of liver metastases from colorectal cancer after surgery ( P = 0.024, 0.019, 0.001, 0.028, < 0.001, 0.001). The primary location of colorectal cancer was positively correlated with lymph node metastasis, D-dimer, and clinical risk score ( P = 0.043, 0.046, 0.030), and negatively correlated with albumin and the efficacy of neoadjuvant chemotherapy ( P = 0.004, 0.033). In 178 patients, the recurrence rate of liver metastases from colorectal cancer at 3 months [53.57% (15/70)], 6 months [55.17% (32/70)], and 12 months [55.68% (49/70)] was significantly higher in the right colon compared with the left colon [32.14% (9/40), 24.14% (14/40), 26.14% (23/40) and the rectum [14.29% (4/68), 20.69% (12/68), 18.18% (16/68)] ( χ2= 4.73, 7.85, 6.27, all P < 0.05). Conclusion:Right colon, lymph node metastasis, D-dimer, albumin, neoadjuvant chemotherapy efficacy, and clinical risk score are the risk factors for postoperative recurrence of liver metastases from colorectal cancer. Patients with the primary location at the right colon have a higher postoperative recurrence rate.

Objective:
To analyze the morbidity, clinical characteristics, therapeutic outcomes and prognosis of cardiac lymphoma.
Methods:
Individual patient data were obtained from pathology defined 10 cases of cardiac lymphoma from Jan 2000 to Jun 2016. The patient’s general information, clinical manifestation, pathological diagnosis, laboratory examination, cardiac involvement feature, cardiac complications, treatment, therapeutic effect and prognosis were analyzed.
Results:
Of 3 918 cases of lymphoma patients, 10 cases of cardiac involvement were identified, including primary cardiac lymphoma (PCL) in 1 case, secondary cardiac lymphoma (SCL) in 9 cases. Of the 10 patients in our analysis, the male-to-female ratio was 3∶2, with a median age of 55 (19-88) years old. The most presenting complaints were dyspnea in 7 cases, followed by chest pain in 5 cases, fatigue in 2 patients and edema in 2 cases. Pathological types included diffuse large B cell lymphoma (DLBCL) in 7 cases, T cell lymphoma (T-LBL) in 1 case, Hodgkin’s lymphoma (HL) in 1 case, and Burkitt lymphoma (BL) in 1 case. The sites of the heart affected by lymphoma in the PCL patient were right and left atriums with multiple nodules; and for SCL, the sites were mainly pericardium associated with a pericardial effusion in 5 cases, a pericardial mass in 2 cases. Congestive heart failure affects 7 patients and cardiac arrhythmias were identified in 4 cases mainly sinus tachycardia, atrial fibrillation and atrioventricular block. Except one untreated because of old age and poor performance, the rest of 9 patients were treated by either chemotherapy in 4 cases or chemotherapy combined radiotherapy (including the extracardiac sites) in 5 patients. With the median follow-up of 9 months, the one PCL patient achieved partial response (PR) , progress free survival (PFS) for 6 months and the overall survival (OS) for 21 months; in the cohort of 6 SCL patients cardiac involved at diagnosis, complete response (CR) was achieved in 1 case (16.7%) , PR in 3 cases, progressing disease (PD) in 2 cases, with the median PFS for 5 months and the median OS for 19 months; and for the other 3 SCL patients cardiac involved at progression, PR was achieved in 2 case and death in 1 case, with the median PFS for 4 months and the median OS unavailable because of censored data.
Conclusion
Cardiac lymphoma represents a rare subset of lymphoma, the most common type is DLBCL, and the main clinical manifestations are dyspnea and chest pain, always combined by arrhythmia and congestive heart failure. The main therapeutic regimen for cardiac lymphoma includes combined chemotherapy and the prognosis for patients with either PCL or SCL is usually poor.

OBJECTIVES:
At present, removable partial denture is still one of the main restoration methods for dentition defects. However, the trend for digital partial denture is becoming more and more obvious in the field of oral repair. However, there are relatively few studies on digital removable partial denture. The aim of this study is to investigate the effects of 3 processing technologies (precision casting, digital cutting, and 3D printing) on the fitness for the clasps of cobalt chromium alloy and pure titanium removable partial denture, and to provide a theoretical basis for the clinical application of digital removable partial denture.
METHODS:
Clasps of Co-Cr alloy and pure titanium were produced by 3 different processing technologies (precision casting, digital cutting, and 3D printing). There are 6 groups, including a casting pure titanium group, a casting cobalt chromium group, a cutting pure titanium group, a cutting cobalt chromium group, a printing pure titanium group, and a printing cobalt chromium group (
RESULTS:
There was no statistical difference in fitness between the casting pure titanium group and the casting cobalt chromium group (
CONCLUSIONS
The cobalt chromium alloy and pure titanium clasps made by precision casting, digital cutting, and 3D printing have good fitness. Under the same process, there is no significant difference between cobalt chromium alloy and pure titanium clasps. The 3D printing pure titanium clasps have better fitness than casting pure titanium and cutting pure titanium clasps, which meet the needs of clinical application.

The promise of regeneration therapy for restoration of damaged myocardium after cardiac ischemic injury relies on targeted delivery of proliferative molecules into cardiomyocytes whose healing benefits are still limited owing to severe immune microenvironment due to local high concentration of proinflammatory cytokines. Optimal therapeutic strategies are therefore in urgent need to both modulate local immunity and deliver proliferative molecules. Here, we addressed this unmet need by developing neutrophil-mimic nanoparticles NM@miR, fabricated by coating hybrid neutrophil membranes with artificial lipids onto mesoporous silica nanoparticles (MSNs) loaded with microRNA-10b. The hybrid membrane could endow nanoparticles with strong capacity to migrate into inflammatory sites and neutralize proinflammatory cytokines and increase the delivery efficiency of microRNA-10b into adult mammalian cardiomyocytes (CMs) by fusing with cell membranes and leading to the release of MSNs-miR into cytosol. Upon NM@miR administration, this nanoparticle could home to the injured myocardium, restore the local immunity, and efficiently deliver microRNA-10b to cardiomyocytes, which could reduce the activation of Hippo-YAP pathway mediated by excessive cytokines and exert the best proliferative effect of miR-10b. This combination therapy could finally improve cardiac function and mitigate ventricular remodeling. Consequently, this work offers a combination strategy of immunity modulation and proliferative molecule delivery to boost cardiac regeneration after injury.
