Abstract
Coronavirus disease 2019 (COVID-19) is the latest respiratory pandemic resulting from zoonotic transmission of severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2). Severe symptoms include viral pneumonia secondary to infection and inflammation of the lower respiratory tract, in some cases causing death. We developed primary human lung epithelial infection models to understand responses of proximal and distal lung epithelium to SARS-CoV-2 infection. Differentiated air-liquid interface cultures of proximal airway epithelium and 3D organoid cultures of alveolar epithelium were readily infected by SARS-CoV-2 leading to an epithelial cell-autonomous proinflammatory response. We validated the efficacy of selected candidate COVID-19 drugs confirming that Remdesivir strongly suppressed viral infection/replication. We provide a relevant platform for studying COVID-19 pathobiology and for rapid drug screening against SARS-CoV-2 and future emergent respiratory pathogens. One Sentence Summary A novel infection model of the adult human lung epithelium serves as a platform for COVID-19 studies and drug discovery.

Abstract
In clinical dentistry practice, supplemental bone surgery or jawbone defect after tooth extraction must be assisted by a bone-filling material. Cobalt-substituted hydroxyapatite (COHA) effectively promotes bone cell growth, reduces the inflammatory response, and is an antibacterial agent. COHA can therefore be used as an alveolar bone-filling material or guided bone regeneration membrane. Meanwhile, COHA can be used in magnetic resonance imaging (MRI) with negative contrast agents and targeting materials without causing metal interference with the image. Hence, COHA has received increasing amounts of attention in recent years. However, the influence of different cobalt precursors on the synthesized COHA is still unknown. Therefore, COHA synthesized from 3 cobalt precursors (cobalt chloride, cobalt nitrate, and cobalt sulfate) was compared in this study. The results show that COHA synthesized by the precursor with the smallest anion radius, cobalt chloride, has a larger particle size (239 nm) and a higher cobalt ion substitution rate (15.6%). When the cobalt ion substitution rate increases, the MRI has a stronger contrast. Bioactivity data indicate that COHAC is more susceptible to degradation and therefore releases more cobalt ions to contribute to the differentiation of bone cells. Based on these studies, COHAC prepared with the cobalt chloride precursor has a higher cobalt ion substitution rate, faster degradation rate, better image contrast, and better bioactivity. It is therefore the preferred choice of bone-filling material for alveolar bone regeneration.

Abstract
Abstract
Background
It is generally acknowledged that those with diabetes mellitus (DM) have at least a 10-fold risk for cardiovascular disease (CVD). However, patients with DM have been shown with a lower incidence of abdominal aortic aneurysm (AAA) in epidemiological data. Related research has illustrated that the aortic may be protected in the hyperglycemic microenvironment while the causality of this relationship is still uncertain.
Purpose
Here, we undertake a two sample Mendelian randomization (MR) study to evaluate whether DM genetically influences the risk of AAA.
Methods
We analyzed the genetic summary data from the DIAGRAM (Diabetes Genetics Replication And Meta-analysis) consortium and MRC-IEU (Integrative Epidemiology Unit) consortium. Base on the result from GIAGRAM consortium (26488 DM cases and 83964 controls), 25 single nucleotide polymorphisms (SNPs) associated with DM as the instrumental variables in MR study. Then, for each of the 25 SNPs associated with DM, we retrieved their summary data from MRC-IEU Consortium (263 cases and 462747controls). Inverse-variance weighting (IVW) was conducted to obtain the associations of DM with AAA and several sensitivity analyses were also performed to assess the potential violation of MR assumptions.
Results
DM was not significantly associated with risk of AAA (odds ratio [OR], 1.ehz746.1092; 95% confidence interval [CI], 0.9998–1.0002; P, 0.9622). Weighted median (OR, 1.0002; 95% CI, 0.9999–1.0005; P, 0.1992) and MR Egger analysis (OR, 1.0003; 95% CI, 0.9995–1.0012; P, 0.4071) suggested similar effect estimates of DM on AAA. With the large P value for the intercept, the result of MR-Egger regression method indicated no evidence for the presence of horizontal pleiotropy (Egger regression intercept, 3.9e-05, P, 0.384). In a leave-one-out analysis, no single SNP was observed with strong driving effect of DM on AAA.
Conclusions
Through 25 genetically identified SNPs in this two sample MR study, DM is not associated the risk of AAA this large study using two-sample MR, which did not support the result from previous epidemiological data. In conclusions, this large MR study provides evidence to suggest that DM may not be causally associated with AAA.

Abstract
Purpose It is uncertain whether right ventricular (RV) lead position in cardiac resynchronization therapy impacts response. There has been little detailed analysis of the activation patterns in RV septal pacing (RVSP), especially in the CRT population. We compare left bundle branch block (LBBB) activation patterns with RV pacing (RVP) within the same patients with further comparison between RV apical pacing (RVAP) and RVSP. Methods Body surface mapping was undertaken in 14 LBBB patients after CRT implantation. Nine patients had RVAP, 5 patients had RVSP. Activation parameters included left ventricular total activation time (LVtat), biventricular total activation time (VVtat), interventricular electrical synchronicity (VVsync), and dispersion of left ventricular activation times (LVdisp). The direction of activation wave front was also compared in each patient (wave front angle (WFA)). In silico computer modelling was applied to assess the effect of RVAP and RVSP in order to validate the clinical results. Results Patients were aged 64.6 ± 12.2 years, 12 were male, 8 were ischemic. Baseline QRS durations were 157 ± 18 ms. There was no difference in VVtat between RVP and LBBB but a longer LVtat in RVP (102.8 ± 19.6 vs. 87.4 ± 21.1 ms, p = 0.046). VVsync was significantly greater in LBBB (45.1 ± 20.2 vs. 35.9 ± 17.1 ms, p = 0.01) but LVdisp was greater in RVP (33.4 ± 5.9 vs. 27.6 ± 6.9 ms, p = 0.025). WFA did rotate clockwise with RVP vs. LBBB (82.5 ± 25.2 vs. 62.1 ± 31.7 op = 0.026). None of the measurements were different to LBBB with RVSP; however, the differences were preserved with RVAP for VVsync, LVdisp, and WFA. In silico modelling corroborated these results. Conclusions RVAP activation differs from LBBB where RVSP appears similar.

Abstract
Objective: To establish comprehensive laboratory reference intervals for Chinese children. Methods: This was a cross-sectional multicenter study. From June 2013 to December 2014, eligible healthy children aged from 6-month to 17-year were enrolled from 20 medical centers with informed consent. They were assessed by physical examination, questionnaire survey and abdominal ultrasound for eligibility. Fasting blood samples were collected and delivered to central laboratory. Measurements of 15 clinical laboratory parameters were performed, including estradiol (E2), testosterone(T), luteinizing hormone(LH), follicle-stimulating hormone(FSH), alanine transaminase(ALT), serum creatinine(Scr), cystatin C, immunoglobulin A(IgA), immunoglobulin G(IgG), immunoglobulin M(IgM), complement (C3, C4), alkaline phosphatase(ALP), uric acid(UA) and creatine kinase(CK). Reference intervals were established according to central 95% confidence intervals for reference population, stratified by age and sex. Results: In total, 2 259 children were enrolled. Finally, 1 648 children were eligible for this study, including 830 boys and 818 girls, at a mean age of 7.4 years. Age- and sex- specific reference intervals have been established for the parameters. Reference intervals of sex hormones increased gradually with age. Concentrations of ALT, cystatin C, ALP and CK were higher in children under 2 years old. Serum levels of sex hormones, creatinine, immunoglobin, CK, ALP and urea increased rapidly in adolescence, with significant sex difference. In addition, reference intervals were variable depending on assay methods. Concentrations of ALT detected by reagents with pyridoxal 5'-phosphate(PLP) were higher than those detected by reagents without PLP. Compared with enzymatic method, Jaffe assay always got higher results of serum creatinine, especially in children younger than 9 years old. Conclusion: This study established age- and sex- specific reference intervals, for 15 clinical laboratory parameters based on defined healthy children.

Abstract
Background Reducing inflammatory factors in wound exudate is a promising treatment approach for healing wounds in postsurgical breast cancer patients. Traditional Chinese Medicine (tcm) treatments have been shown to be beneficial and safe for optimal regulation of oxidative stress during the postoperative period. In the present clinical trial, we evaluated the effectiveness of a promising Chinese herbal formula, San Huang decoction [shd (Radix astragali, Radix et rhizoma rhei, and Rhizoma curcuma longa, 3:1:1; supplemental Table 1)], on wound inflammatory response after mastectomy. Methods The study randomized 30 patients with breast cancer who fulfilled the inclusion and exclusion criteria to either a treatment (n = 15) or a control group (n = 15). Patients in the treatment group received liquid shd, taken twice daily with or without food. Treatment was given for 1 day before surgery and for 7 days postoperatively. Participants in the control group received a placebo on the same schedule as the treatment group. Outcomes measured in every subject included clinical tcm and wound inflammation symptom scores, daily and total amounts of drainage fluid, and levels of inflammatory factors in the exudate [tumour necrosis factor α (tnf-α), interleukins 6 (il-6), 8 (il-8), and 2R (il-2R), human C-reactive protein (crp)] at 2 hours and on days 1, 3, and 7 postoperatively. Results The total amount of drainage fluid over 7 days was significantly lower in the treatment group (572.20 ± 93.95 mL) than in the control group (700.40 ± 107.38 mL). The tcm symptom score was also lower in treatment group (day 7: 1.87 ± 0.83 vs. 4.80 ± 3.61, p = 0.049), as was the inflammatory symptom score (day 7: 0.67 ± 0.72 vs. 3.67 ± 2.50, p = 0.001). Levels of tnf-α, il-6, il-8, il-2R, and crp in drainage fluid were significantly lower with shd treatment. Conclusions Perioperative treatment with shd effectively lessened postoperative exudate and ameliorated inflammatory symptoms in patients who underwent surgery for breast cancer.

Abstract
SUMMARY
Objective:
This study aimed to investigate the long-term effectiveness of ceramic–resin bonding with universal adhesives in non–silane-pretreated and silane-pretreated modes after 10,000 cycles of thermal aging.
Methods and Materials:
All Bond Universal, Adhese Universal, Clearfil Universal Bond, and Single Bond Universal were selected. Etched lithium disilicate glass ceramics were prepared, randomly assigned to groups, and pretreated with or without ceramic primer containing silane coupling agent prior to the application of universal adhesive (ie, silane-pretreated or non–silane-pretreated mode). The shear bond strength (SBS), microleakage, and field-emission scanning electron microscopy images of the ceramic–resin interfaces were examined after 24 hours of water storage or 10,000 thermal cycles. Light microscopy and confocal laser scanning microscopy (CLSM) were performed to analyze marginal sealing ability.
Results:
SBS and microleakage percentage were significantly affected by bonding procedure (non–silane-pretreated or silane-pretreated mode) and aging (24 hours or 10,000 thermal cycles). After the universal adhesives in the non–silane-pretreated mode were aged, SBS significantly decreased and microleakage percentage increased. By contrast, the SBS of Adhese Universal, Clearfil Universal Bond, and Single Bond Universal decreased, and the microleakage percentage of all of the adhesives increased in the silane-pretreated mode. However, after aging, the SBS of the silane-pretreated groups were higher and their microleakage percentages lower than those of the non–pretreated groups. In the non–silane-pretreated mode, adhesive failure was dominant and gaps between composite resin and the adhesive layer were significant when observed with CLSM.
Conclusions:
The simplified procedure reduced the ceramic–resin bonding effectiveness of universal adhesives after aging, and additional silane pretreatment helped improve the long-term durability.

Abstract
Objective: To investigate and analyze the distribution of 121 diseases of China's First List of Rare Diseases based on hospitalized patients of tertiary hospitals and to explore the current situation of rare diseases in China. Methods: Based on previous data of study from Beijing Society of Rare Diseases, a comparison between China's First List of Rare Diseases and the survey list from the pre-study was performed. Descriptive analysis was carried out on the current situation of rare diseases on hospitalizations in 96 tertiary hospitals from year of 2014 to 2015. Results: Nineteen out of 121 diseases on China's First List of Rare Diseases were not included in the rare diseases survey list of Beijing Society of Rare Diseases. The total number of other 102 rare disease cases was 54 468, accounting for 0.35% of the inpatients during the same period. The top ten most and least cases with rare disease were demonstrated in this study. The number of the top ten most cases was 37 977, accounting for 0.25% of the inpatients during the same period. The number of the top ten least cases was 24, accounting for 0.000 16% of the inpatients during the same period. The top most five types of rare diseases counted on the provinces and municipalities were Beijing, Hunan, Shanghai, Shandong and Guangdong. The top five most cases of rare diseases counted on the provinces and municipalities were Beijing, Shanghai, Guangdong, Shandong and Hubei. The age distribution showed that the cases with rare diseases aged 25-64 years accounted for 45.8%, and the cases in children aged 0-14 accounted for 28.6%. The top ten readmission rate ranged from 28.42% to 64.88%. Conclusions: This study preliminarily investigates the number, type, province and municipality distribution, age distribution, and readmission rate of 121 rare diseases from China's First List of Rare Diseases in the hospitalized patients of tertiary hospitals, which provides important data for registration study, medical and drug policy making and other relevant work on rare diseases in China in the future.

Abstract
AIM Counselling patients and their relatives about non-curative management options in colorectal cancer is difficult because of a paucity of published data. This study aims to determine outcomes in patients unsuitable for curative surgery and the rates of subsequent surgical intervention. METHOD This was an analysis of all colorectal cancers managed without curative surgery in a district general hospital from a prospectively maintained cancer registry between 2009 and 2016, as decided by a multidisciplinary team. Primary outcomes were overall survival and secondary outcomes were subsequent intervention rates and impact of tumour stage. RESULTS In all, 183 patients out of 976 patients (18.8%) were identified. The median age at diagnosis was 81 years [interquartile range (IQR) 71-87 years]. Overall median survival from diagnosis was 205 days (IQR 60-532 days). One-year mortality was 62.3%. Patients were classified into two groups depending on the reason for a non-curable approach: patient-related (PR) or disease-related (DR). The difference in survival between PR (median 277 days, IQR 70-593) and DR (median 179 days, IQR 51-450) was 98 days (P = 0.023). Twenty-four patients were alive at the end of the study period; 19 out of 91 cases in PR (20.8%) and five out of 92 cases in DR (5.4%). Overall intervention rates were 11.9%, with higher rates in the DR group (P = 0.005). Disease stage was not associated with subsequent surgical intervention between the two groups (P = 0.392). CONCLUSION Life expectancy for non-curatively managed patients within our unit was 6.8 months with one in nine patients requiring subsequent surgical admission for palliation. This information may be useful when counselling patients with incurable colorectal malignancy.

Abstract
Objective: To evaluate the differential diagnosis of idiopathic granulomatous mastitis (IGM) and invasive ductal carcinoma. Methods: The ultrasonographic data of 37 IGM patients and 50 cases of IDC were analyzed retrospectively. The shape, growth direction, margin, internal echo, posterior echo, calcification, Adler blood flow classification, PSV(peak sestolic velocity), RI (resistance index)and elasticity scores were analyzed by χ(2) test and independent sample t test. The optimal cutoff values of age, PSV and RI were calculated by receiver operating characteristic (ROC) curve. Logistic regression analysis was used to calculate the odds ratio (OR) of ultrasonic variates in the diagnosis of both diseases. Results: There were no significant differences in the shape, margin, internal echo and blood flow grading between the two groups. The age, lesion growth direction, posterior echo, calcification, PSV, RI and elasticity were statistically different. The cut-of value of Age, PSV and RI were 38.5 years old, 13.20 cm/s, and 0.655. Logistic regression multi-variated analysis revealed that elastic score (OR=9.806) had the best value of the differential diagnosis, as well as calcification (OR=6.937), posterior echo decay (OR=4.613), RI (OR=3.257), lesion growth orientation (OR=3.198), and PSV (OR=1.202). Lesion shape, margin, internal echo, and Adler blood flow classification did not help in differential diagnosis. Conclusion: Ultrasound multi-parameter analysis has high value in IGM and IDC differential diagnosis.

Abstract
The entorhinal cortex (EC) is one of the most vulnerable brain regions that is attacked during the early stage of Alzheimer's disease (AD). Here, we report that the synaptic terminals of pyramidal neurons in the EC layer II (ECIIPN) directly innervate CA1 parvalbumin (PV) neurons (CA1PV) and are selectively degenerated in AD mice, which exhibit amyloid-β plaques similar to those observed in AD patients. A loss of ECIIPN-CA1PV synapses disables the excitatory and inhibitory balance in the CA1 circuit and impairs spatial learning and memory. Optogenetic activation of ECIIPN using a theta burst paradigm rescues ECIIPN-CA1PV synaptic defects and intercepts the decline in spatial learning and memory. These data reveal a novel mechanism of memory loss in AD mice via the selective degeneration of the ECIIPN-CA1PV pathway.

Abstract
BACKGROUND Icotinib has been previously shown to be non-inferior to gefitinib in non-selected advanced non-small-cell lung cancer patients when given as second- or further-line treatment. In this open-label, randomized, phase 3 CONVINCE trial, we assessed the efficacy and safety of first-line icotinib versus cisplatin/pemetrexed plus pemetrexed maintenance in lung adenocarcinoma patients with epidermal growth factor receptor (EGFR) mutation. PATIENTS AND METHODS Eligible participants were adults with stage IIIB/IV lung adenocarcinoma and exon 19/21 EGFR mutations. Participants were randomly allocated (1 : 1) to receive oral icotinib or 3-week cycle of cisplatin plus pemetrexed for up to four cycles; non-progressive patients after four cycles were maintained with pemetrexed until disease progression or intolerable toxicity. The primary end point was progression-free survival (PFS) assessed by independent response evaluation committee. Other end points included overall survival (OS) and safety. RESULTS Between January 2013 and August 2014, 296 patients were randomized, and 285 patients were treated (148 to icotinib, 137 to chemotherapy). Independent response evaluation committee-assessed PFS was significantly longer in the icotinib group (11.2 versus 7.9 months; hazard ratio, 0.61, 95% confidence interval 0.43-0.87; P = 0.006). No significant difference for OS was observed between treatments in the overall population or in EGFR-mutated subgroups (exon 19 Del/21 L858R). The most common grade 3 or 4 adverse events (AEs) in the icotinib group were rash (14.8%) and diarrhea (7.4%), compared with nausea (45.9%), vomiting (29.2%), and neutropenia (10.9%) in the chemotherapy group. AEs (79.1% versus 94.2%; P < 0.001) and treatment-related AEs (54.1% versus 90.5%; P < 0.001) were significantly fewer in the icotinib group than in the chemotherapy group. CONCLUSIONS First-line icotinib significantly improves PFS of advanced lung adenocarcinoma patients with EGFR mutation with a tolerable and manageable safety profile. Icotinib should be considered as a first-line treatment for this patient population.
