Abstract
OBJECTIVE To detect the binding of Mage-D1 with activated p75NTR and explore their role in regulating mineralization of ectomesenchymal stem cells (EMSCs). METHODS EMSCs were isolated from the tooth germs of embryonic SD rats (19.5 days of gestation) by tissue explant culture and were identified for surface markers using flow cytometry. The cultured cells were divided into blank control group, 100 ng/mL nerve growth factor (NGF) stimulation group, and lentivirus-mediated Mage-D1 interference (SH-Mage-D1) group. Proximity ligation assay was used to detect the binding of Mage-D1 with activated p75NTR in the EMSCs, and the binding strength was compared among the 3 groups. Alizarin red staining and ALP staining were used to observe mineralization of the induced cells. The expressions of ALP, Runx2, OCN, BSP, OPN, Msx1 and Dlx1 at both the mRNA and protein levels were detected using RT-PCR and Western blotting. RESULTS The isolated EMSCs expressed high levels of cell surface markers CD44, CD90, CD29, CD146, and CD105 with a low expression of CD45. The results of proximity ligation assay showed that the binding of Mage-D1 with activated p75NTR in the cells increased over time, and the binding strength was significantly greater in NFG-treated cells than in the cells in the other two groups (P < 0.05). Alizarin red staining and ALP staining of the induced cells showed that the changes in the mineralization nodules were consistent with those of ALP activity. The cells treated with 100 ng/mL NGF exhibited significantly increased expressions of ALP, Runx2, OCN, BSP, OPN, Col1, Msx1 and Dlx1 as compared with the cells in the other two groups (P < 0.05). CONCLUSION Mage-D1 directly binds to activated p75NTR in embryonic rat EMSCs to positively regulate the mineralization of the EMSCs.

Abstract
Background Aortic regurgitation is the most common cardiovascular damage in Chinese patients with Behçet’s disease (BD) and is usually associated with aortic disease. These patients are easily misdiagnosed, and their prognosis is poor, even after surgical treatment. This study aimed to analyse potential factors that can improve the prognosis of BD patients with aortic regurgitation and/or aortic involvement. Methods Twenty-two patients with diagnosed or suspected BD as well as aortic regurgitation and/or aortic involvement in our hospital from 2012 through 2017 were collected in this study. Their clinical characteristics were listed, and the diagnosis of BD was evaluated by two different criteria sets. The influences of surgical treatment and immunosuppressive therapy (IST) on their prognosis were also explored. Results The diagnostic positive rate of the International Criteria for Behçet’s Disease was higher than that of the International Study Group criteria (kappa value 0.31, p < 0.05), indicating that the diagnostic consistency between the criteria sets was poor. There was no significant difference in survival between patients who had undergone ≤ 1 operation and those with ≥ 2 operations. Aortic valve replacement alone or in combination with aortic root replacement had no significant effect on the incidence of reoperation or death, but IST did significantly reduce this incidence (p < 0.05). However, there was no significant difference in the occurrence of reoperation or death between preoperative and postoperative IST versus postoperative IST only. Conclusion IST significantly improved the prognosis of BD patients with aortic regurgitation and/or aortic involvement.

Abstract
OBJECTIVE The long non-coding RNA DDX11 antisense RNA 1 (DDX11-AS1) was found to be highly expressed in gastric cancer (GC). This study was to explore the role and molecular mechanism in oxaliplatin (OXA) resistance. PATIENTS AND METHODS The levels of DDX11-AS1, microRNA-326 (miR-326) and insulin receptor substrate 1 (IRS1) were measured by quantitative Real-time polymerase chain reaction (qRT-PCR). Cell proliferation, migration, invasion and apoptosis were examined by methylthiazolyldiphenyl-tetrazolium bromide (MTT), transwell and flow cytometry assays, respectively. Levels of all protein were detected using Western blot. The correlation between miR-326 and DDX11-AS1/IRS1 was confirmed by Dual-Luciferase reporter and RNA immunoprecipitation (RIP) assays. The xenograft model was constructed to explore the effect of DDX11-AS1 in vivo. RESULTS DDX11-AS1 was overexpressed in OXA-resistant GC tissues and cells, and DDX11-AS1 knockdown inhibited cell proliferation, migration, invasion and OXA resistance, and promoted apoptosis in OXA-resistant GC cells. Mechanically, DDX11-AS1 directly targeted miR-326 and miR-326 could bind to IRS1 in OXA-resistant GC cells. Functionally, silencing DDX11-AS1 repressed the progression and OXA resistance in OXA-resistant GC cells by down-modulating IRS1 expression via sponging miR-326 in vitro and in vivo. CONCLUSIONS DDX11-AS1 accelerated the progression and OXA chemoresistance of GC cells in vitro and in vivo by sponging miR-326, thus increasing the expression of IRS1, suggesting DDX11-AS1 might be a promising prognostic biomarker and therapeutic target in GC.

Abstract
AIMS Esteya vermicola is an endoparasitic fungus producing lunate conidia, which kill pine wood nematode (PWN), and PWN could cause pine wilt disease (PWD). The aims of this study were to increase production and confirm the resistance (temperature and UV irradiation) of lunate conidia, and further determine the effective concentrations of conidia infecting PWN. METHODS AND RESULTS In this study, rice was used as a carrier to absorb conidial suspension to propagate conidia. The optimal conditions for lunate conidia production were 25°C temperature, 9 days of culture time, 2 : 1 rice/distilled water ratio and 10% inoculum size. The germination rate of E. vermicola cultured on potato dextrose agar was influenced by UV irradiation, similar to growth on rice. Esteya vermicola cultured on rice under heat stress might be more suitable for application in the field. The concentration (1 × 108 conidia per ml) to kill PWN had the highest infectivity among the four conidia concentrations tested after 3 days of inoculation. CONCLUSIONS This study showed a rice substrate-supported high-quality conidia production and the optimal infectivity concentration of E. vermicola. SIGNIFICANCE AND IMPACT OF THE STUDY These results provide the necessary process of an economical and efficient biological control strategy against PWD.

Abstract
Objective: To explore and analyze the clinical characteristics, diagnosis and treatment of infant hairy polyp. Methods: A retrospective analysis was made on 13 cases of hairy polyp confirmed by pathology, who were admitted to the Children's Hospital of Hebei Province from January 2010 to September 2019, including 4 males and 9 females, with a male-female ratio of 1∶2.25. The age ranged from 3 hours to 1 year, and the median age was 1 month. Twelve of the 13 children were found to have difficulty breathing or feeding. All the children received coblation resection under general anesthesia. The root pedicle of the mass was found in the lateral nasopharyngeal wall in 8 cases, in the junction of palatine and palatopharyngeal arch of tonsil and the tongue and esophageal entrance in 1 case, respectively. Nasal septum was found in 2 cases, including 1 case located between two incisors. The wound at the root pedicle was ablated and the bleeding was stopped completely. Results: Postoperative follow-up lasted from 3 months to 2 years, and there was no recurrence in 12 cases. Fibrolaryngoscope showed a mass of the right eustachian tube and pharyngeal mouth in 1 case 2 years after the surgery, which was considered recurrence of hairy polyps and lost after that. Conclusion: Hairy polyps in infants is a rare clinical disease, and its main symptom is upper respiratory tract obstruction. Early diagnosis and radical surgery are the key to the treatment of the disease.

Abstract
AIMS To investigate the effects of Lactobacillus plantarum on inflammatory responses induced by ETEC K88 and explore the underlying molecular mechanisms. METHODS AND RESULTS Intestinal porcine cells (IPEC-1) were incubated with 0 or 1 × 108 CFU per well L. plantarum for 4 h, and then these cells were challenged with 0 or 1 × 108 CFU per well ETEC K88 for 2 h. The results showed that pre-treatment of IPEC-1 cells with L. plantarum prevented the increases in the transcript abundance of interleukin-1α (IL-1α), interleukin-6 (IL-6), interleukin-8 (IL-8) and tumour necrosis factor-α (TNF-α) (P < 0·05) caused by ETEC K88. Additionally, L. plantarum inhibited the reduction in peroxisome proliferator-activated receptor-γ (PPAR-γ) expression caused by ETEC K88 (P < 0·05). Moreover, L. plantarum pre-treatment downregulated the phosphorylation levels of c-Jun N-terminal kinase (JNK), extracellular regulated protein kinases 1 and 2 (ERK1/2) and p38 and the nuclear concentration of nuclear factor kappa B p65 (NF-κB p65) (P < 0·05) compared with ETEC K88 group. Silencing experiment further supported that the protective effect of L. plantarum P might mediated by suppression of ETEC-provoked activation of MAPK and NF-κB signalling pathways. CONCLUSIONS Lactobacillus plantarum inhibited the inflammatory response induced by ETEC K88 in IPEC-1 cells via modulating MAPK and NF-κB signalling. SIGNIFICANCE AND IMPACT OF THE STUDY This study elucidated the underlying mechanism in which probiotics protect against intestinal inflammation caused by ETEC K88.

Abstract
INTRODUCTION Regional lymph node metastasis is an important prognostic factor for patients with gastric cancer. Occult tumour cells (OTCs), including either micrometastases (MMs) or isolated tumour cells (ITCs), may be a key factor in the development of cancer recurrence in pN0 patients. AIMS We aimed to determine the frequency and prognostic significance for disease recurrence of OTCs. MATERIALS AND METHODS This retrospective cohort study included all consecutive patients with pN0 gastric adenocarcinoma between January 2000 and December 2011 (n = 73). Immunohistochemistry using the pan-cytokeratin antibody AE1/AE3 was used to detect OTCs in 1257 isolated lymph nodes. RESULTS OTCs were identified in 30 patients (41%), including 20 cases with MMs (27%) and 10 cases with ITCs (14%). Disease recurrence and cancer-related death were observed in 24 (33%) and 20 patients (27%), respectively, and both were significantly associated with the detection of OTCs. A significant difference was also observed for the mean survival time between patients with OTCs and those without OTCs [100 vs 158 months (p = 0.015)]. The presence of OTCs was statistically significantly associated with the Lauren classification, tumour size and lymphatic permeation. Multivariate analyses revealed that only age, T stage and the presence of ITCs in lymph nodes were independent factors for recurrence. The presence of ITCs increased the risk for recurrence by 11.1-fold. CONCLUSIONS In a significant proportion of patients diagnosed as stage pN0, OTCs may be identified in lymph nodes if carefully searched for, which can negatively affect their prognosis. The presence of ITCs was found to be an independent factor for recurrence and after proper validation should be considered during lymph node assessment for prognosis definition.

Abstract
OBJECTIVES Monocyte-derived macrophages, as the predominant immune cell type that is increased in inflamed synovium, play a vital role during knee osteoarthritis (KOA) progression. However, the mechanisms underlying the recruitment of circulating monocytes to osteoarthritic knees remain uncertain. Based on previous data obtained from plasma, we investigated the contributions of CCL2, CCL3, CCL4 and their cognate receptors in circulating monocyte chemotaxis and KOA development. METHODS Using flow cytometry staining, we characterized the expression patterns of the chemokine receptors in CD14+CD16- circulating monocytes from KOA patients and healthy volunteers. The expression of chemokines in synovial fluids, synovium and cartilage was investigated in KOA patients and in patients without KOA. The role of chemokines and their cognate receptors in the chemotaxis of CD14+CD16- circulating monocytes was assessed using chemokine neutralizing antibodies (NA) and receptor antagonists in vitro and in vivo. RESULTS The majority of CD14+CD16- circulating monocytes were CCR1-and CCR2-positive. CCL2, CCL3 and CCL4 were elevated in synovial fluid of KOA patients compared with that of controls. The most likely source of these chemokines is inflamed synovium and cartilage in the osteoarthritic knee. The CCL3/CCR1 and CCL2/CCR2 axes showed substantial ability to recruit CD14+CD16- monocytes in transwell assays. Similar results were confirmed in a mouse model of collagenase-induced KOA (CIA) in which blocking either the CCL3/CCR1 axis or the CCL2/CCR2 axis reduced synovial hyperplasia and F4/80+ macrophage infiltration. CONCLUSIONS Our findings suggested that, analogous to the CCL2/CCR2 axis, CCL3 produced in osteoarthritic knees can chemoattract circulating monocytes to the inflamed synovium through CCR1.

Abstract
PURPOSE Both glucagon-like peptide-1 (GLP-1) and glucagon (GCG) belong to the incretin family. This study aimed to investigate the pharmacokinetics and pharmacodynamics of DR10601, a fully recombinant hybrid peptide with dual GLP-1/GCG receptor agonistic activity. METHODS The agonistic ability of DR10601 was indirectly assessed by inducing cAMP accumulation in Chinese hamster ovary cells transfected with GLP-1R or GCGR in vitro. Following s.c. administration, the plasma pharmacokinetics of DR10601 were analysed in male Sprague-Dawley rats. The antiobesity effects and improved glycaemic control of DR10601 in vivo were evaluated by administering DR10601 to high-fat DIO mice and ICR mice as a single dose or repeated s.c. doses once every 4 days for 24 days. RESULTS DR10601 exhibits dual agonistic activity on GLP-1 and glucagon receptors. The plasma half-life of DR10601 in Sprague-Dawley rats following s.c. administration was 51.9 ± 12.2 h. In an IPGTT, a single s.c. dose of DR10601 (30 nmol/kg) produced similar glycaemic control effects and a longer duration of action compared to dulaglutide (10 nmol/kg). Compared with that achieved with liraglutide (40 nmol/kg) s.c. administered daily, DR10601 administered s.c. once every 4 days at 90 nmol/kg exerted a nearly equivalent effect on food intake and significantly reduced the body weights of high-fat DIO mice at 24 days. CONCLUSIONS Repeated administration of DR1060 provides potent and sustained glycemic control and body weight loss effect in high-fat DIO mice. DR10601 is a promising long-acting agent deserving further investigation for the treatment of type 2 diabetes and obesity.

Abstract
We show unequivocal evidence for formation of He_{2}^{*} excimers in liquid He II created by ionizing radiation produced through neutron capture. Laser beams induce fluorescence of the excimers. The fluorescence is recorded at a rate of 55.6 Hz by a camera. The location of the fluorescence is determined with an uncertainty of 5 μm. The technique provides an opportunity to record the flow of He_{2}^{*} excimers in a medium with very small viscosity and enables measurement of turbulence around macroscopic liter size objects or vortex matter in three dimensions.

Abstract
The first official general medicine was established in the United States, and society of general medicine established in 1947. After that the European and American countries began to study of general medicine and construct system. In 1966, the commonwealth launched the first global residency training program in general medicine.At present, many countries have formed a perfect general practitioner training system. In 1988, the concept of general medicine was introduced into China. In 1989, the Chinese Medical Association established the General Medicine Education Committee, marked the beginning of general medical education in China. In 1993, General Medicine Branch of Chinese Medical Association was set up, was a symbol of the birth of general medicine in China. Compared with some European and American countries, China's general medicine was a late starter, and the training of general practitioners has experienced the development of diversification, at present, it is in line with the international training mode.

Abstract
Objective: To understand the characteristics of 24 388 inpatients with rare diseases in Zhejiang province during 2007-2017 and provide evidence for rare disease prevention and control. Methods: Inpatient data of rare diseases and the number of hospitalization in each year were collected in 10 hospitals of class Ⅲ (A) in Zhejiang province from 2007 to 2017, and descriptive statistical analysis was used. Results: A total of 24 388 cases of rare diseases were found, accounting for 2.69‰ (24 388/9 054 201) of total hospitalized cases. The top 3 types of rare diseases were "diseases of blood and blood-forming organs and certain disorders involving immune mechanism" (32.81%, 8 001/24 388), "congenital malformations, deformations and chromosomal abnormalities" (24.87%, 6 065/24 388) and "diseases of the nervous system" (19.01%, 4 635/24 388). The number of rare disease cases increased year by year from 2007 to 2017 with an average annual growth of 19.69%, however, the proportion of rare disease cases in the annual number of hospitalized cases only showed upward trend during 2016-2017, the time distribution of different types of rare diseases had different characteristics. The male to female ratio of rare diseases cases was 1.35∶1(13 990/10 398), "diseases of the digestive system" (4.45∶1, 1 180/265), "consequences of injury, poisoning and other external causes" (3.51∶1, 281/80) and "diseases of the nervous system" (2.26∶1, 3 213/1 422) had the highest male to female ratio. The distributions of rare disease types and diseases of different types in different age groups varied. The top 10 rare diseases accounted for 53.55% (13 060/24 388) of the total cases, and the top 3 diseases were adult idiopathic neutropenia (14.41%, 3 515/24 388), corticobasal degeneration (7.60%, 1 854/24 388) and henock-schoenlein purpura (6.01%, 1 466/24 388). Conclusion: The analysis on the characteristics of 24 388 rare disease cases in Zhejiang during 2007-2017 provided reference evidence for the promotion of rare disease research, monitoring, building registration database, and development of the prevention and control strategy for rare diseases in China.

Abstract
Objective:To analyze the secondary pulmonary infection and the distribution of pathogenic bacteria in children with tracheobronchial foreign body, and to guide the clinical treatment. Method:The clinical data of 197 children with tracheobronchial foreign bodies confirmed by rigid bronchoscopy were reviewed. According to the clinical manifestations and signs, blood routine, chest CT and airway endocrine pathogen distribution, the secondary pulmonary infection was analyzed. Result:Seventy-five of 197 children with foreign bodies in tracheobronchial had secondary pulmonary infections. Among them, 32 cases of airway endocrine cultured pathogenic bacteria, mainly including Streptococcus pneumoniae and Haemophilus influenzae. Children with long preoperative history, fever, and with a history of using antibiotics are more likely to have secondary pulmonary infections. Conclusion:The duration of disease history, preoperative fever and the use of antibiotics are related to secondary pulmonary infection. The third generation of cephalosporins can effectively control the infection.

Abstract
Clinical trials have previously assessed various therapies for renal cell carcinoma (RCC); however, there is currently a lack of direct comparisons between these therapies. The present study identified published studies on RCC through Web of Science, PubMed, EMBASE, Cochrane Library of Controlled Trials and Clinical trials.gov that were written in the English language and published by February 2019. The data were selected and extracted independently by two reviewers. Standard pair-wise meta-analyses were performed using Stata. Network meta-analyses were subsequently performed using WinBUGS (version 1.4.3). The primary outcome of the present study was progression-free survival (PFS). Secondary outcomes included overall survival (OS), objective response rate (ORR) and adverse events of various targeted therapies. The results were presented as cumulative odds ratio, hazard ratio, corresponding 95% confidence interval and the surface under the cumulative ranking curve, which was used to rank the probabilities and outcome of each treatment in RCC. A total of 31 eligible publications for 18 randomized controlled trials consisting of 11,498 participants were included in the present study. The network meta-analyses revealed that a combination of lenvantinib and everolimus ranked first out of 16 treatments in terms of PFS, OS and ORR (probability of 54.0, 53.4 and 61.0%, respectively).
