AIM: To evaluate the associations between development of retinopathy of prematurity (ROP) and serum lymphocyte-to-monocyte ratio (LMR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR). METHODS: A retrospective cohort study was performed, involving infants who were screened for ROP from January 2015 to December 2015. Preterm newborns of ≤32 gestational weeks with ROP were enrolled as the observation group, and non-ROP infants were enrolled as the control group, whose complete blood cell were measured within the first 24h of life. The levels of NLR, LMR and PLR were determined in all groups. The data obtained were analyzed using univariate and multivariate logistic regression analysis. RESULTS: In this study, 40 cases of ROP were enrolled and 40 cases of non-ROP as controls. The LMR levels were significantly higher (P

- Abstract
The application of object detection technology has been used in people's daily lives widely, and it can be used accurately in traffic scenes is also crucial. Based on the YOLOX object detection model, a lightweight neural network for traffic object detection is proposed. First, we propose S-PANet (Simple Path Aggregation Network) structure based on the YOLOX_S baseline model. The purpose of the S-PANet structure is to reduce the parameters number of models and the amount of floating-point computation in training. Second, we propose to add CBAM (Convolutional Block Attention Module) to the network based on the S-PANet. Adding CBAM attention mechanism can improve the detection accuracy of models, but has less computation added. It is a compensation of the simplification on feature pyramid. Final, we carry out the lightweight experiments on three kinds of models, including S, Tiny, and Nano. The proposed methods are verified on KITTI and PASCAL VOC datasets. Our S model can achieve 92.9% mAP@0.5 and 21.33 FPS on KITTI dataset. The Tiny and Nano models can achieve 84.3%, 79.4% mAP@0.5 and 33.07, 41.67 FPS respectively. Compared with the baseline models, the detection accuracies mAP@0.5 have less difference and the parameters number of the models are reduced.

7. Multi-Spatial Pyramid Feature and Optimizing Focal Loss Function for Object Detection

- Abstract
Previous deep convolutional neural network research has made significant progress toward improving the speed and accuracy of object detection. However, despite these advancements, the inaccurate detection of multi-object (small objects) remains challenging in the traffic environments. In this article, we propose a new architecture called YOLOM, which is specifically designed to achieve enhanced multi-object (small objects) detection precision. YOLOM incorporates several innovative features: a multi-spatial pyramid (MSP), an optimized focal loss (OFLoss) function, and an objectness loss that incorporates effective intersection over union (EIoU) calculations. These features collectively yield enhanced accuracy and reduce the miss rate of small objects, particularly in the multi-object cases. According to the sizes of receptive field features with different spatial scales with pooling layers, we propose the MSP module. We optimize the focal loss as a classification function instead of the cross-entropy loss, which solves some class imbalance problems caused by anchor-free detection when encountering disparate datasets. Due to the superior performance of EIoU in confidence scoring, we use EIoU to participate in the objectness loss calculation of our work. Therefore, our method substitutes EIoU for YOLOX's objectness loss. The experimental results demonstrate that our strategies significantly outperform some end-to-end object detection methods.

Ectopic thoracic kidneys are the rarest form of renal ectopia. Moreover, congenital abnormality of a primary anterior inferior vena cava (IVC) located behind the anterior abdominal wall is extremely rare. To date, only one such case has been reported. Herein, we report a rare case of a 55-year-old Chinese male with bilateral thoracic kidneys combined with an anterior IVC, a malformed liver, and a large-round-folds navel. The classification, clinical characteristics, and management options of a thoracic kidney was also summarized by literature review. To our best knowledge, the simultaneous detection of such multiple complex abnormalities has not been reported.

Background: To investigate the epidemiologic features of breast cancer laterality and molecular subtypes in Southern China, we retrospectively analyzed the clinical data of patients with a definite diagnosis of breast cancer in 2013-2017. Methods: Data for inpatient hospitalization associated with breast cancer were obtained from the Affiliated Hospital of Guangdong Medical University, Guangdong Province, South China. Around 2060 cases who were diagnosed with unilateral breast cancer for the past 5 years were classified based on laterality and molecular subtypes. Molecular subtypes were defined in accordance with the 2013 St. Gallen recommendations. All statistical analyses were performed using Statistical Product and Service Solutions version 21 and Excel version 2010. Results: Breast cancer is more likely to be diagnosed in the left breast than in the right by around 5%. In both in situ and invasive carcinomas, the right breast is more commonly affected than the left in young (

Introduction Dynamin 3 (DNM3) is a large GTPase that possesses mechanochemical properties and has been shown to be involved in malignancies. However, most studies about DNM3 are observational, and knowledge of the precise molecular mechanism of DNM3 remains limited. Materials and methods We constructed a PCDH-CMV-MCS-EF1a-GFP-Puro-DNM3 recombinant eukaryotic expression vector, which was then transfected into SW620 and LoVo cells. One cell line was divided into three groups. DNM3 mRNA and protein expression was analyzed by quantitative real-time PCR and Western blot assay. To investigate DNM3 biological activity in colon cancer SW620 and LoVo cell line, we performed cell proliferation, transwell migration, and invasion assay. Matrix metalloproteinase (MMP)-2 and MMP-9 protein expressions were detected by Western blot. Result We successfully constructed a PCDH-CMV-MCS-EF1a-GFP-Puro-DNM3 recombinant eukaryotic expression vector, and stable DNM3 expression was observed in SW620 and LoVo cell lines. The vector overexpressing DNM3 inhibited the proliferation, weak invasion, and migration ability of colon cancer SW620 and LoVo cells relative to those in the control group (all P

We conducted a meta-analysis of the association between YB-1 expression and the survival and clinicopathological features in NSCLC. Methods: PubMed and Embase were searched to identify studies that evaluated the YB-1 expression (by immunohistochemistry) and overall survival (OS) in NSCLC. Hazard ratios (HRs) and 95% confidence intervals (CI) of OS were pooled. Odds ratios (ORs) of clinicopathological features were computed. Meta-analysis was performed using STATA 12.0 software. Results: Data on 692 NSCLC patients were collected from six eligible studies. Meta-analysis revealed that YB-1 was associated with worse OS (HR = 1.59, 95% CI [1.27, 2.00], P < 0.001, fixed effect), tumor stage (OR = 0.43, 95% CI [0.22-0.82], P = 0.01, random effect), and depth of invasion (OR = 0.37, 95%CI [0.22-0.63], P < 0.001, fixed effect). A subgroup was analyzed by IHC staining to determine the location of YB-1 positive expression. Poor OS was observed in nucleus staining (pooled HR = 1.86, 95% CI [1.41, 2.45], P < 0.001). However, no statistical significance was observed in combined cytoplasmic and nuclear staining (pooled HR = 1.14, 95% CI [0.76, 1.72], P = 0.536). Conclusions: Meta-analysis indicated that YB-1 overexpression is correlated with worse OS and clinicopathological features in NSCLC. Subgroup analysis revealed that the nucleus expression of YB-1 may be more closely associated with NSCLC prognosis than cytoplasmic expression.

Radiotherapy is a vital treatment option for patients with nasopharyngeal carcinoma (NPC). Concurrent cisplatin-based radiochemotherapy with or without adjuvant chemotherapy had acquired good clinical effects with good local control rates. However, a number of patients present with metastasis following systemic regimens or initial diagnosis of locally advanced NPC, which cause difficulty for subsequent therapy. Therefore, there is an urgent requirement to discover novel targeted therapies. The present report describes one case of a patient with NPC and multiple metastases. The patient was treated with systemic therapy in combination with bevacizumab, palliative radiotherapy and chemotherapy following treatment with cetuximab and concurrent chemoradiotherapy in 2015. Following the addition of bevacizumab, metastases were reduced or disappeared after >2 months, and the duration of progression-free survival was 7 months. Bevacizumab is a monoclonal antibody that targets VEGF, and it is associated with angiogenesis, which causes the growth, invasion and progression of tumors. In previous studies, bevacizumab has been approved for the treatment of several types of malignant cancer and it has been able to effectively improve prognosis. In the present review, the effect of adding bevacizumab to systemic therapy for the treatment of NPC was analyzed, with a particular focus on advanced and metastatic diseases. A growing number of phase I/II clinical trials involving bevacizumab for NPC have been conducted with clinical outcomes showing improved rates of overall survival and progression-free survival as well as improvements in the quality of life of patients. However, severe or deadly toxicities can also result from combination treatment with bevacizumab. In the future, bevacizumab may become a common addition to systemic therapy for the treatment of locally advanced and metastatic NPC.

Background: The objective of this study was to explore the influence factors of hospitalization costs of treating colorectal cancer in China. And the study provides new estimates on hospitalization costs and length of hospital stay for patients with colorectal cancer in China. Methods: Data for inpatient hospitalization associated with colorectal cancer were obtained from a 3-tier hospital in Guangdong Province and were analyzed post hoc. We conducted descriptive statistical methods, Wilcoxon rank–sum tests (for 2 groups) and the Kruskal–Wallis test (for more than 2 groups) to analyze the hospitalization costs of treating colorectal cancer. Results: The analysis included 8021 patients (female: 40.54%; mean age; 61.80 ± 13.28 years; male: 59.46%; mean age: 61.80 ± 13.28 years). The overall mean length of hospital stay was 11.35 days. Over the 5 years, the mean length of hospital stay showed a small decrease from 12.22 days in 2012 to 10.69 days in 2016, while per-day costs showed a trend of increase between 2012 and 2015 (increase from

Primary pulmonary paraganglioma is a rare disease. We report a case of a 37-year old female patient with space-occupying lesions in the right lower pulmonary lobe during a routine examination without any symptoms. The patient underwent video-assisted thoracoscopic surgery (VATS) resection of the right middle lobe and dissection of hilar and mediastinal lymph nodes under general anesthesia. She recovered without recrudescence. Preoperative diagnosis is difficult. Accurate diagnosis requires pathological examination, and immunohistochemical test is particularly important. Complete resection is the first treatment option for solitary primary pulmonary paraganglioma; however, VATS is a better technique. Given the high local control rates and few complications of radiotherapy, it is considered as a standard treatment.
