Exosomes are extracellular vesicles that regulate various signaling pathways in the body by mediating the release of proteins, nucleic acids and lipids, thus playing an important role in pathophysiological processes such as inflammation, tumor, immunity and nervous system. More and more studies have shown that exosomal non-coding RNA (ncRNA) plays a crucial role in pancreatic diseases. This article reviews the role of exosome ncRNA in the occurrence, diagnosis and treatment of pancreatic diseases such as acute pancreatitis and pancreatic cancer, in order to provide a reference for clinical practice.

Objective: To investigate the timing of pericardial drainage catheter removal and restart of the anticoagulation in patients with atrial fibrillation (AF) suffered from perioperative pericardial tamponade during atrial fibrillation catheter ablation and uninterrupted dabigatran. Methods: A total of 20 patients with pericardial tamponade, who underwent AF catheter ablation with uninterrupted dabigatran in Beijing Anzhen Hospital from January 2019 to August 2021, were included in this retrospective analysis. The clinical characteristics of enrolled patients, information of catheter ablation procedures, pericardial tamponade management, perioperative complications, the timing of pericardial drainage catheter removal and restart of anticoagulation were analyzed. Results: All patients underwent pericardiocentesis and pericardial effusion drainage was successful in all patients. The average drainage volume was (427.8±527.4) ml. Seven cases were treated with idarucizumab, of which 1 patient received surgical repair. The average timing of pericardial drainage catheter removal and restart of anticoagulation in 19 patients without surgical repair was (1.4±0.7) and (0.8±0.4) days, respectively. No new bleeding, embolism and death were reported during hospitalization and within 30 days following hospital discharge. Time of removal of pericardial drainage catheter, restart of anticoagulation and hospital stay were similar between patients treated with idarucizumab or not. Conclusion: It is safe and reasonable to remove pericardial drainage catheter and restart anticoagulation as soon as possible during catheter ablation of atrial fibrillation with uninterrupted dabigatran independent of the idarucizumab use or not in case of confirmed hemostasis.

Objective:To explore the expressions of long non-coding RNA LINC00673 and ISG15 protein in pancreatic cancer and their clinical significances.Methods:The clinical data of 57 patients diagnosed as pancreatic ductal carcinoma (PDAC) at the Affiliated Cancer Hospital of Xiangya Medical College of Central South University from January 2014 to December 2018 were retrospectively analyzed. The relative expressions of LINC00673 in pancreatic cancer tissues and paracancerous normal tissues (within 3 cm from the edge of cancer tissues) were examined by using quantificational reverse transcription-polymerase chain reaction (qRT-PCR). The ISG15 protein expressions in pancreatic cancer tissues and paracancerous normal tissues were examined by using immunohistochemistry. The difference in LINC00673 expression between ISG15 protein positive and negative patients was compared. The correlation between LINC00673 and ISG15 protein expressions in pancreatic cancer was analyzed by Spearman rank correlation analysis. Moreover, the correlations of LINC00673 and ISG15 protein expressions with clinical stage and pathological classification of pancreatic cancer patients were analyzed.Results:The positive expression of ISG15 protein in pancreatic cancer tissues was 40.4% (23/57), which was higher than that in paracancerous normal tissues [15.8% (9/57)] ( χ2 = 7.90, P = 0.004), and the relative expression of LINC00673 in pancreatic cancer tissues was 0.99±0.36, which was lower than that in paracancerous normal tissues (1.26±0.41) ( t = 4.80, P < 0.001). For 23 (40.4%) ISG15-positive patients and 34 (59.7%) ISG15-negative patients, the relative expression of LINC00673 was 0.77±0.46 and 0.45±0.27 ( P < 0.001). Spearman analysis showed that there was a correlation between LINC00673 and ISG15 protein expressions ( ρ = -0.429, P = 0.001). The relative expression of LINC00673 decreased in patients with low differentiated or undifferentiated tumor, vascular invasion and lymph node metastasis (all P < 0.05), but there was no correlation between LINC00673 expression and patients' age, tumor site, preoperative CA199 level, and TNM stage (all P > 0.05); ISG15 protein expression increased in patients with low differentiated or undifferentiated tumor, TNM stage Ⅲ-Ⅳ, vascular invasion and lymph node metastasis (all P < 0.05), but there was no correlation between ISG15 protein expression and patients' gender, age, tumor site, and preoperative CA199 level (all P > 0.05). Conclusions:The expression of LINC00673 in pancreatic cancer is related to vascular invasion, tumor differentiation degree and lymph node metastasis, and the expression of ISG15 in pancreatic cancer is related to vascular invasion, tumor differentiation degree, lymph node metastasis and TNM stage. The combined detection of LINC00673 and ISG15 protein could be a valuable prognostic indicator for pancreatic cancer. The therapies targeting LINC00673 and ISG15 protein signaling pathways are expected to be a potential option for immunotherapy of pancreatic cancer.

Objective: To determine the characteristics and progress of the visual acuity and refractive state of schoolchildren in Huangzhong District, Xining City, Qinghai Province in China. Methods: Cohort study. Department of Ophthalmology, Beijing Children's Hospital carried out a cohort study by collecting the visual acuity and refractive state of Grade 1-5 schoolchildren among 16 primary schools in Huangzhong District, Xining City, Qinghai Province in September 2020 and July 2021. Cycloplegic retinoscopy with eye drop which contained tropicamide (0.5%) and phenylephrine hydrochloride (0.5%) was performed in children with low vision(<1.0). Myopia was defined as the spherical equivalent (SE) ≤-0.5 D after cycloplegic retinoscopy. Measurement data was analyzed by t-test and enumeration data was analyzed by χ² test. Multiple linear regression was used to analyze the influencing factors. Results: The 2 489 individuals with repeated tests in two years were included in the follow-up study, among whom the prevalence of myopia was 26.24%(653/2 489) in 2020, while 32.94% (820/2 489)respectively in 2021. The incidence of myopia in one school year from grades 1 to 5 was 11.19%(47/420), 5.44%(21/386), 6.39%(25/391), 11.52%(44/382) and 11.67%(30/257). The average SE of children in all grades in 2021 increased negatively from the previous year (Grade 1 to Grade 5 increased respectively: 0.40 D, 0.69 D, 0.62 D, 0.52 D and 0.37 D). Conclusions: The prevalence of myopia among schoolchildren in Huangzhong District, Xining City, Qinghai Province was relatively high. There were two peaks of myopia incidence in the first, fourth and fifth grades. Female, age, and the baseline of SE were the related influencing factors for myopia progression.

OBJECTIVE: To examine the effect of the aqueous extract of Ligustrum robustum on tumor growth in vitro and in vivo and explore the possible molecular mechanisms. METHODS: In in vitro study, cell viabilities of human cervical carcinoma cells (HeLa), human breast cancer cells (MCF-7), human prostate cancer cells (PC-3), human hepatoma cells (7721) and human colon carcinoma cells (SW480) were evaluated with cell counting kit-8. For L. robustum-treated Hela cells, early or late apoptosis were evaluated by annexin V/PI staining. Mitochondrial membrane potential was measured by staining cells with JC-1. Apoptosis was monitored by nuclear morphology based on chromatin condensation and fragmentation by 4',6-diamidino-2-phenylinole (DAPI) staining. Caspase-3 and -8 activity levels were measured by a colorimetric assay. In vivo, to evaluate the possible mechanism of L. robustum-mediated antitumor effect, nude mouse xenograft study was also conducted. RESULTS: In in vitro study, L. robustum was found to be toxic to HeLa, MCF-7, PC-3, 7721, SW480, with an half maximal inhibitory concentration value of 2-5 mg/mL (P<0.05). Moreover, externalization of phosphatidylserine, loss of mitochondrial membrane potential, DNA fragmentation and activation of caspase-3 and -8 were detected in L. robustum-treated Hela cells. Using a nude mouse model bearing Hela xenografts, we found that L. robustum reduced tumor volume and tumor weight (P<0.05), but had no effect on body weight and histological damage of important organs. Intraperitoneal injection of L. robustum caused a significant reduction in serum aspartate transaminase and alanine transaminase levels (P<0.05). Furthermore, cleaved caspase-3-positive and terminal nucleotidyl transferase-mediated nick end labeling (TUNEL)-positive cells were observed in L. robustum-treated tumor tissues. CONCLUSIONS L. robustum inhibits tumor cell growth both in vitro and in vivo by inducing apoptosis in a caspase-dependent way without apparent hepatic toxicity and histological damage, which may offer partial scientific support for the ethnopharmacological claims of L. robustum as a herbal tea for its antitumor activity.

Objective: To investigate the effect and mechanism of Mailuoning Compound for treatment of early steroid-induced osteonecrosis of femoral head (SONFH) in rats by obturator nerve block. Method: 24 rats were injected with endotoxin 10 μg·kg^-1 through tail vein. After 24 hours, prednisolone acetate 20 mg·kg^-1 was given by intraperitoneal injection, once every 24 hours for 3 consecutive days. After successful modeling, the rats were randomly divided into the model group (n=12), the treatment group (n=12) and the normal control group (n=6). In the treatment group, 2 mL·kg^-1 of Mailuoning compound was injected into the obturator nerve from the 4th day, 3 times a week for 8 weeks. The arterial blood was collected from rats on the first day of the 9th week after model building to detect the content of blood lipid; the femoral head was taken to prepare the paraffin section, and the pathological changes of femoral head was observed and the changes of empty bone lacuna rate, bone trabecular area and bone lacuna area were quantitatively analyzed; The changes of bone morphogenetic proteins(BMPs),transforming growth factor-β₁(TGF-β₁),vascular endothelial cell growth factor(VEGF),and Ⅷ factor related antigen(Ⅷ-R Ag) were quantitatively analyzed by immunohistochemical method. Result: In the model group, the bone trabeculae were sparse, thin, disorganized and broken; some of the bone cells were necrotic and the number of empty bone lacunae was increased. In the treatment group, the number of trabeculae was increased; the structure was clear, most of which was normal bone cells, with a few necrotic bone cells, and the number of empty bone lacunae was decreased obviously. The rate of empty bone lacuna and the area of bone lacuna in the treatment group were significantly lower than those in the model group (P<0.05);the positive area ratio of VEGF, BMPs, TGF-β₁ and the microvessel density of Ⅷ-R Ag in the treatment group were significantly higher than those in the model group (P<0.05), with significantly lower blood lipid contents (P<0.05). Conclusion: Mailuoning compound can improve the microcirculation state of femoral head, promote the formation of new bone and blood vessel in femoral head by regulating the expression of VEGF, BMPs, TGF-β₁, Ⅷ-R Ag and down-regulating blood lipid content, thus effectively controlling the development of early SONFH. This can provide a theoretical basis for the treatment of early SONFH.

AIM:To investigate the natural course and adverse event of branch retinal vein occlusion (BRVO) rat model induced by laser photochemical method. METHODS: Thirty SD (Sprague Dawley) rats were administrated Bangladesh via tail vein. Then 532nm laser (80mW, 100μ m and 100ms) was performed on retinal vein secondary bifurcation of bitamporal optic disk for 50 spots. Electroretinogram (ERG), fundus fluorescein angiography ( FFA), optical coherence tomography (OCT) and fundus (fluorescein) photograph were applied on 1, 3, 5, 7, 10, 14 and 21d after BRVO model constructed. Two rats were sacrificed, respectively, on 1, 5 and 21d after photocoagulation to carry on HE (Hematoxylin - Eosin stain) and VEGF - α (vascular endothelial growth factor - α) immumohistochemical staining. RESULTS: There were three rats died, three rats with severe retinal detachment for excessive bleeding,one rat with retinal sunken, and one rat with cataract. FFA and fundus ( fluorescein) photograph showed that the successful BRVO rat model was 73% (22/30). It was found that the near-end photocoagulation vein became coarse, far - end became diminution on 1d and the photocoagulation vein total recanalization was on 3-7d. ERG showed the amplification of b wave (dark -adaptation 3.0 response) decreased to 0.694士0.042 of control eyes and on 5-7d decreased to rock bottom about 0.487士0.064 of control eyes. Then it increased Aii the time to 0.708士0.0465 of control eyes on 21d. OCT and HE staining found that retinal ganglion cells and outer nuclear layer became edema on 1d in vivo and in vitro.It was observed that the thickness of retina on photocoagulation vein (0μ m or 250μ m) decreased from 5d and there were 3-4 layer cells in ONL on 21d. The expression of VEGF-α at injured site were significantly more than control eyes on 1d and there were no significant difference on 5d;But the expression of VEGF-α were slightly less than control eyes on 21d. CONCLUSION: Photochemical method was a feasible method to establish BRVO rat model. The evolution and development of the BRVO model could partly mimic human BRVO phenomenon. At the same time, it should be improved to increase the successful model rate.

Objectives: To investigate the prevalence of ideal cardiovascular health behaviors and factors, and its association with socioeconomic status (SES) in enterprise employees. Methods: The cluster sampling method was adopted to recruit 27 607 employees aged 18 to 60 years from 45 enterprises across China. The ideal cardiovascular health metrics including behaviors and factors, which were defined according to the AHA criteria, were obtained, and SES was measured by education and occupational class. Multilevel logistic regression models were used to analyze the association between SES and ideal cardiovascular health metrics. Results: Overall, the prevalence of ideal cardiovascular health behavior (smoking, body mass index, salt intake, physical activity) was 51.3%, 67.9%, 14.0%, 31.2%, respectively; prevalence of the ideal cardiovascular factors (fasting blood glucose, total cholesterol, blood pressure) was 72.9%, 81.6%, 27.3%,respectively in this cohort. Among the employees, only 0.6% population met all 7 cardiovascular health metrics. After adjusting the individual and workplace factors, employees with high school (OR=1.18, 95%CI: 1.08-1.29) and college or above education (OR=1.52, 95%CI: 1.37-1.69) were more likely to have ideal cardiovascular health status compared with those with less education; white-collar workers were more likely to have ideal cardiovascular health status compared with blue-collar workers (OR=1.18; 95%CI: 1.08-1.29). Conclusions: The prevalence of ideal cardiovascular health behaviors and factors is low, and is positively associated with SES, suggesting the importance of promoting the cardiovascular health behavior, monitoring/controlling the related cardiovascular factors and reducing the socioeconomic inequalities among Chinese enterprise employees.
