Abstract
BACKGROUND Early diagnosis of atrial fibrillation is important as it is crucial for improving patient outcomes. Fibroblast growth factor-2 (FGF2) may serve as a diagnostic biomarker for heart failure due to its ability to promote cardiac fibrosis and hypertrophy; however, the relationship between FGF2 concentration and heart failure is unclear. Therefore, this study aimed to explore whether FGF2 could aid in distinguishing patients with heart failure from healthy controls and those with dyspnea without heart failure. Additionally, to evaluate the possible correlation between serum FGF2 levels and its diagnostic parameters in patients with heart failure. METHODS Plasma FGF2 concentration was measured in 114 patients with a complaint of dyspnea (enrolled in the study between January 2022 and August 2022). Based on heart failure diagnosis, the patients were assigned to three groups, as follows: heart failure (n = 80), non-heart-failure dyspnea (n = 34), and healthy controls (n = 36), following physical examination. Possible correlations between serum FGF2 levels and other prognostic parameters in patients with heart failure were analyzed. RESULTS Serum FGF2 levels were higher in patients with heart failure (125.60 [88.95, 183.40] pg/mL) than in those with non-heart-failure dyspnea (65.30 [28.85, 78.95] pg/mL) and healthy controls (78.90 [60.80, 87.20] pg/mL) (p < 0.001). Receiver operating characteristic curve analysis identified FGF2 concentration as a significant predictor in heart failure diagnosis, with an area under the curve of 0.8693 (p < 0.0001). Importantly, in the heart failure group, serum FGF2 concentrations correlated with key prognostic parameters for heart failure, such as reduced left ventricular ejection fraction and elevated serum levels of N-terminal pro-B-type natriuretic peptide. CONCLUSIONS Elevated serum FGF2 level is strongly associated with an increased risk of heart failure and could serve as a useful biomarker to complement vital diagnostic parameters for heart failure.

Abstract
INTRODUCTION Metastasis is the primary cause of lung cancer-related death. Nevertheless, the underlying molecular mechanisms and evolutionary patterns of lung cancer metastases are still elusive. METHODS We performed whole-exome sequencing for 40 primary tumors (PTs) and 61 metastases from 47 patients with lung cancer, of which 40 patients had paired PTs and metastases. The PT-metastasis genomic divergence, metastatic drivers, timing of metastatic dissemination, and evolutionary origins were analyzed using appropriate statistical tools and mathematical models. RESULTS There were various degrees of genomic heterogeneity when comparing the paired primary and metastatic lesions or comparing metastases of different sites. Multiple metastasis-selected/enriched genetic alterations were found, such as MYC amplification, NKX2-1 amplification, RICTOR amplification, arm 20p gain, and arm 11p loss, and these results were were also featured in a meta-analysis cross-validated using an independent cohort from Memorial Sloan-Kettering Cancer Center database. To elucidate the metastatic seeding time, we applied a metastatic model and found 61.1% of the tumors were late dissemination, in which the metastatic seeding happened approximately 2.74 years before clinical detection. One exception was lymph node metastases whose dissemination time was relatively early. By analyzing the evolutionary origins, we reported that nonlymph node metastases were mainly seeded by the PT (87.5%) rather than the earlier colonized lymph node metastases. CONCLUSIONS Our results shed light on the molecular features that potentially drive lung cancer metastases. The distinct temporospatial pattern of disease progression revealed that lung cancer was susceptible to either late dissemination or indolent early lymph node metastases, leaving a potential time window to minimize metastases by early cancer detection.

Abstract
Intron retention (IR) is an alternative splicing mode whereby introns, rather than being spliced out as usual, are retained in mature mRNAs. It was previously considered a consequence of mis-splicing and received very limited attention. Only recently has IR become of interest for transcriptomic data analysis owing to its recognized roles in gene expression regulation and associations with complex diseases. In this article, we first review the function of IR in regulating gene expression in a number of biological processes, such as neuron differentiation and activation of CD4+ T cells. Next, we briefly review its association with diseases, such as Alzheimer's disease and cancers. Then, we describe state-of-the-art methods for IR detection, including RNA-seq analysis tools IRFinder and iREAD, highlighting their underlying principles and discussing their advantages and limitations. Finally, we discuss the challenges for IR detection and potential ways in which IR detection methods could be improved.

Abstract
Objective: To investigate the situation of sexual partners and related factors among men who have sex with men (MSM) in college students. Methods: Snowball sampling and Convenience sampling were both used to recruit MSM from colleges in Tsingtao in 2016. Questionnaire-based interviews were conducted to collect data of socio-demographic and situation of sexual partners. Sample Size was estimated based on cross-sectional study, and theoretical 267. SPSS 17.0 software was used for statistical analysis. Results: A total of 300 MSM, average aged 20.7, were analyzed. Both first sex partner and the last same-sex sexual partner were met instantly, with proportions as 58.7% (176/300) and 62.3% (187/300) respectively. Among all the MSM, 88.3% (265/300) preferred selecting men as sex partners and 42.7% (128/300) enjoyed finding sex partners in college, while 86.0% (258/300) preferred finding their sex partners through internet. Conclusions: Internet had been the major way of looking for sex partner among MSM in college students, the male sexual partner were met instantly. We should focus on men who have sex with men and their sexual health among college students to prevent and control HIV/AIDS.

Abstract
BACKGROUND Paclitaxel (PTX) has remarkable anti-tumor activity, but it causes severe toxicities. There is an urgent need to seek an appropriate pharmacokinetic parameter of PTX to improve treatment efficacy and reduce adverse effects. OBJECTIVE To evaluate the association of pharmacokinetic parameter TC > 0.05 of paclitaxel (PTX) and its therapeutic efficacy and toxicity in patients with solid tumors. METHODS A total of 295 patients with ovarian cancer, esophageal cancer, breast cancer, and non-small cell lung cancer (NSCLC), who were admitted to the Tumor Hospital of Shantou University Medical College, China, were recruited for this study. Patients received 3 weeks of PTX chemotherapy. The plasma concentrations of PTX were examined using the MyPaclitaxel™ kit. The patients' PTX TC > 0.05 (the time during which PTX plasma concentration exceed 0.05µmol/L) were calculated based on pharmacokinetic analysis. RESULTS The results showed that: (1) the concentrations of PTX in these 295 patients ranged from 0.0358-0.127 µmol/L; (2) the PTX TC > 0.05 ranged from 14 to 38h with a median time of 27h; (3) among all treatment cycles, there was a statistically significant difference in the PTX TC > 0.05 between CR+PR and SD+PD; (4) with the increasing value of TC > 0.05, level of leukopenia and leukopenic fever increased; (5) high PTX TC > 0.05 led to the occurrence of neutropenia, neutropenic fever, severe anemia, and severe peripheral neurotoxicity. Taken together, our results indicated that the pharmacokinetic parameter PTX TC > 0.05 was an effective measure of treatment efficacy and toxicity in patients with solid tumors. Maintaining PTX TC > 0.05 at 26 to 30h could improve its efficacy and reduce the incidence of leukopenia, neutropenia, anemia, and peripheral neurotoxicity in these patients. CONCLUSION PTX TC > 0.05 is a key pharmacokinetic parameter of PTX which should be monitored to optimize individual treatment in patients with solid tumors.

Abstract
OBJECTIVE To build the rat model of gastric precancerous lesions and discuss the effect of transplantation of mesenchymal stem cells (BMMSCs) on the pathological change. METHODS The rat model of gastric precancerous lesions was built using N-methyl-N'-nitro-N'-nitrosoguanidine. After the intravenous transplantation of BMMSCs, the migration and colonization location was then observed, as well as its effect on the related factors of gastric precancerous lesions, including VEGF, IL-10 and IFN-γ. RESULTS BMMSCs were mainly colonized in the gastric body and gastric antrum, which could be differentiated into the epithelial and interstitial cells. The expression of VEGF in the transplantation group and non-transplantation group was significantly higher than that in the control group (P < 0.05); while the expression of VEGF in the transplantation group was significantly higher than that in the non-transplantation group (t = 3.88, P < 0.001). The expression of serum IL-10 and IFN-γ in the transplantation group and non-transplantation group was significantly higher than that in the control group (P < 0.05), while the expression of IL-10 and IFN-γ in the transplantation group was significantly lower than that in the non-transplantation group (t = 3.03, P = 0.004; t = 3.80, P < 0.001). CONCLUSIONS BMMSCs can be directionally differentiated into the epithelial and interstitial cells and can also regulate the related growth factors and inflammatory factors to reduce the injury of inflammation, relieve or reverse the process of gastric precancerous lesions.

Abstract
AIM: To evaluate the therapeutic effects, treatment strategies, clinicopathologic features, and prognosis of gastric-neuroendocrine carcinoma (G-NEC).
METHODS: According to the 2010 World Health Organization (WHO) classification of NEC, clinical data for 44 patients with G-NEC were analyzed retrospectively, including treatment methods, pathological features and prognosis.
RESULTS: All the 44 patients were followed. The median survival of these patients was 23.5 mo, and the overall 1-, 3- and 5-year survival rates were 70.8%, 25.3% and 12.0%, respectively. Univariate analysis showed that age, gender, tumor size, and tumor location were not correlated with prognosis, but surgical procedure, invasive depth, lymph node and distant metastases were significantly correlated with prognosis.
CONCLUSION: G-NEC has a high recurrence rate and poor prognosis. The prognosis depends on multiple factors such as carcinoma infiltration and metastasis and surgical treatment. Multidisciplinary treatment should be given in these cases.

Abstract
Red bayberry (Myrica rubra Seib. & Zucc.) has great economic importance in eastern and southern China. However, increasing cultivation of red bayberry has resulted in an increase in diseases such as leaf necrosis. In April 2011, a survey was conducted to identify the causal agents of leaf necrosis of red bayberry (cv. Biqi) in Cixi City, Zhejiang Province. Symptoms began with oval and pale brown lesions (2 mm in diameter) that developed into a round to irregular shape (4 to 12 mm in diameter) with pale brown centers and dark brown borders. After approximately 4 months, necrotic lesions expanded to the leaf tips or margins. Black acervuli developed on lesions at later stages. Leaf tissues were surface sterilized with 0.5% sodium hypochlorite for 3 min and rinsed in sterile water before plating onto potato dextrose agar (PDA). Seven isolates were obtained from four samples from four fields on PDA at 25°C. The colonies were cottony white with filiform edges and produced a honey yellow color into the agar at 7 days. Conidia were produced in ink-like fruiting bodies at 4 days at 25°C on PDA. Conidia were straight or slightly curved, fusiform, and five celled with constrictions at the septa. Conidia ranged from 18.7 to 25.8 × 6.2 to 7.7 μm with hyaline apical and basal cells. Thirteen percent of the apical cells had two and the rest had three hyaline appendages ranging from 11.2 to 26.0 μm long. Basal appendages were hyaline, straight, and varied from 3.6 to 5.8 μm long. The color of three median cells was light to dark brown and demonstrated versicolorous. These morphological characteristics matched those of Pestalotiopsis sydowiana (Bresadola) Sutton (1). The morphological identification of the fungus was confirmed by nucleotide blast analysis of the 5.8S subunit and flanking internal transcribed spacers (ITS1 and ITS2) of rDNA regions (GenBank Accession No. JQ322999), which revealed 100% with those of other P. sydowiana isolates (e.g., GenBank Accession No. FJ478105). Koch's postulates were confirmed with 20 healthy leaves of the same size on three branches of three plants in the field. Leaves were wounded by pressing slightly with sterile needles. Mycelial plugs (5 mm in diameter) obtained from the periphery of 7-day-old cultures were placed onto the wounds and covered with sterile-water-saturated cotton. Wounded leaves treated with sterile agar plugs served as controls. The inoculated leaves were sealed in moist plastic bags for 24 h to establish high humid conditions at 21 to 30°C. After 23 days, symptoms on all inoculated leaves were identical to those described above, whereas noninoculated control leaves did not show any symptoms. The fungus was consistently reisolated from the lesions. To our knowledge, this is the first report of P. sydowiana causing leaf necrosis of M. rubra in China. Results can help to better understand the diseases threatening red bayberry trees and develop effective control strategies for better fruit production. Reference: (1) E. F. Guba.

Abstract
OBJECTIVE To evaluate the risk factors of postoperative complications after reoperation for recurrent Crohn disease(CD). METHODS From 1995 to 2009, 65 patients undergoing reoperation for recurrent CD were identified in the First Affiliated Hospital of Fujian Medical University. Risk factors of postoperative complications were analyzed. These patients were matched by age to 65 patients undergoing primary operation and treatment outcomes were compared between primary operation and reoperation. RESULTS Postoperative complications were observed in 25 cases(38.5%) undergoing reoperation for CD recurrence and the rate of postoperative complication was higher than that after primary operation(12.3%). Postoperative complications rate in patients with stoma was significantly lower than those without stoma(15.8% vs. 47.8%, χ(2)=5.831, P=0.016). Compared to primary operation, reoperation had longer operative time, more severe intraperitoneal adhesion, and a longer postoperative hospital stay(all P<0.05). CONCLUSION Reoperation for CD recurrence is associated with higher postoperative complications. Temporary stoma may decrease the rate of postoperative complication.
