Abstract
Surgical resection remains the prefer option for bladder cancer treatment. However, the effectiveness of surgery is usually limited for the high recurrence rate and poor prognosis. Consequently, intravesical chemotherapy synergize with immunotherapy in situ is an attractive way to improve therapeutic effect. Herein, a combined strategy based on thermo-sensitive PLEL hydrogel drug delivery system was developed. GEM loaded PLEL hydrogel was intravesical instilled to kill tumor cells directly, then PLEL hydrogel incorporated with CpG was injected into both groins subcutaneously to promote immune responses synergize with GEM. The results demonstrated that drug loaded PLEL hydrogel had a sol-gel phase transition behavior in response to physiological temperature and presented sustained drug release, and the PLEL-assisted combination therapy could have better tumor suppression effect and stronger immunostimulating effect in vivo. Hence, this combined treatment with PLEL hydrogel system has great potential and suggests a clinically-relevant and valuable option for bladder cancer.

Abstract
Water residue and replacement difficulty cause insufficient adhesive infiltration in demineralized dentin matrix (DDM), which produces a defective hybrid layer and thus a bonding durability problem, severely plaguing adhesive dentistry for decades. In this study, we propose that the unique properties of a highly hydrated interface of the porous DDM can give rise to 1 new type of interface, confined liquid water, which accounts for most of the residue water and may be the main cause of insufficient infiltration. To prove our hypothesis, 3 metal ions with increasing binding affinity and complex stability (Na+, Ca2+, and Cu2+) were introduced respectively to coordinate negatively charged groups such as -PO43-, -COO- abundant in the DDM interface. Strong chelation of Ca2+ and Cu2+ rapidly released the confined water, significantly improving penetration of hydrophobic adhesive monomers, while Na+ had little effect. A significant decrease of defects in the hybrid layer and a much decreased modulus gap between the hybrid layer and the adhesive layer greatly optimized the microstructure and micromechanical properties of the tooth-resin bonding interface, thus improving the effectiveness and durability of dentin bonding substantially. This study paves the way for a solution to the core scientific issue of contemporary adhesive dentistry: water residue and replacement in dentin bonding, both theoretically and practically.

Abstract
Dentin bonding is the most common form of human tissue repair among tissue-biomaterial adhesions, concerning billions of people's oral health worldwide. However, insufficient adhesive infiltration in the demineralized dentin matrix (DDM) always produces numerous defects in the bonding interface termed the hybrid layer, which causes high levels of bacteria-related secondary dental diseases, and less than 50% of the bonding lasts more than 5 years. Therefore, it is urgent and vital to construct an antibacterial low-defect hybrid layer to solve the durability-related problems. A DDM with a hydrogel-like surface formed by the hydration of highly-anionic non-collagenous proteins (NCPs) is firstly used as a template to electrostatically assemble polyethyleneimine (PEI). The formation of a stable antibacterial polyelectrolyte complex of PEI/NCPs rapidly eliminates NCP hydration capacity and significantly improves the infiltration of various adhesives. Simultaneously, both the PEI during the assembly and the PEI-assembled DDM can directly destroy a biofilm of S. Mutans on the DDM. Consequently, a long-term antibacterial and low-defect hybrid layer is successfully created, which greatly improves the bonding effectiveness. This helps to improve the clinical treatment of bacteria-based dental diseases and the tooth-restoration repair effect and prevent secondary dental diseases, having significance in clinical dentistry and providing insights for other tissue-biomaterial adhesions.

Abstract
β decay of proton-rich nuclei plays an important role in exploring isospin mixing. The β decay of ^{26}P at the proton drip line is studied using double-sided silicon strip detectors operating in conjunction with high-purity germanium detectors. The T=2 isobaric analog state (IAS) at 13 055 keV and two new high-lying states at 13 380 and 11 912 keV in ^{26}Si are unambiguously identified through β-delayed two-proton emission (β2p). Angular correlations of two protons emitted from ^{26}Si excited states populated by ^{26}P β decay are measured, which suggests that the two protons are emitted mainly sequentially. We report the first observation of a strongly isospin-mixed doublet that deexcites mainly via two-proton decay. The isospin mixing matrix element between the ^{26}Si IAS and the nearby 13 380-keV state is determined to be 130(21) keV, and this result represents the strongest mixing, highest excitation energy, and largest level spacing of a doublet ever observed in β-decay experiments.

Abstract
Objectives
Mood disorders and strokes are often comorbid, and their health toll worldwide is huge. This study characterizes prognostic and etiological roles of mood disorders in stroke.
Methods
We tested if genetic susceptibilities for mood disorders could predict future strokes using the Malmö Diet and Cancer cohort (24 631 individuals). Additionally, Mendelian randomization was employed to further examine the causality using summary statistics from large genome wide association studies (mood disorders: up to 287,932 individuals; strokes: up to 446,696 individuals).
Results
Among 24,366 stroke-free participants at baseline, 2,632 individuals developed strokes, 2,172 of them ischemic, during a follow-up of up to 25 years. After all adjustments, participants in the highest quintile (5th quintile) of polygenic risk scores (PRS) for mood disorders had 1.46x (95% confidence interval (CI): 1.22–1.74) higher risk of strokes and 1.45x (95% CI: 1.19–1.77) higher risk of ischemic strokes compared to the lowest quintile (1st quintile) of PRS in women. Univariable and multivariable Mendelian randomization analyses showed that mood disorders had causal effect on smoking (odds ratio (OR) = 1.19, 95% CI: 1.07–1.31), type 2 diabetes mellitus (T2D, OR=1.22, 95% CI: 1.04–1.43) and women's body mass index (BMI, coefficient = 0.11, 95% CI: 0.01–0.21), whereas causal effects for smoking, T2D and BMI on stroke/ischemic stroke were consistently observed.
Conclusion
Our results suggest that mood disorders can cause stroke through smoking, T2D and BMI. Using PRS, women, who benefit from prevention and treatment of smoking, T2D and BMI, could possibly be early identified to prevent mood disorders and strokes.

Abstract
The fungal pathogen Cryptococcus neoformans is a leading cause of meningoencephalitis in the immunocompromised. As current antifungal treatments are toxic to the host, costly, limited in their efficacy, and associated with drug resistance, there is an urgent need to identify vulnerabilities in fungal physiology to accelerate antifungal discovery efforts. Rational drug design was pioneered in de novo purine biosynthesis as the end products of the pathway, ATP and GTP, are essential for replication, transcription, and energy metabolism, and the same rationale applies when considering the pathway as an antifungal target. Here, we describe the identification and characterization of C. neoformans 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR) transformylase/5'-inosine monophosphate cyclohydrolase (ATIC), a bifunctional enzyme that catalyzes the final two enzymatic steps in the formation of the first purine base inosine monophosphate. We demonstrate that mutants lacking the ATIC-encoding ADE16 gene are adenine and histidine auxotrophs that are unable to establish an infection in a murine model of virulence. In addition, our assays employing recombinantly expressed and purified C. neoformans ATIC enzyme revealed Km values for its substrates AICAR and 5-formyl-AICAR are 8-fold and 20-fold higher, respectively, than in the human ortholog. Subsequently, we performed crystallographic studies that enabled the determination of the first fungal ATIC protein structure, revealing a key serine-to-tyrosine substitution in the active site, which has the potential to assist the design of fungus-specific inhibitors. Overall, our results validate ATIC as a promising antifungal drug target.

Abstract
Objective: To analyze the prenatal diagnosis results and pregnancy outcomes of conotruncal defects (CTD) fetuses, and to explore the correlation between the CTD and chromosome diseases. Methods: A total of 297 cases of invasive prenatal diagnosis and chromosome analysis were collected at the Prenatal Diagnosis Center of Guangzhou Women and Children's Medical Center due to CTD from January 1st, 2011 to December 31th, 2019. According to ultrasonic diagnosis, CTD fetuses were divided into 6 subtypes: tetralogy of Fallot (109 cases), pulmonary atresia (30 cases), transposition of the great arteries (77 cases), double outlet right ventricle (53 cases), truncus arteriosus (14 cases) and interrupted aortic arch (14 cases). According to whether they were combined with intracardiac or extracardiac abnormalities, they were divided into simple group (134 cases), combined with other intracardiac abnormalities group (86 cases), combined with extracardiac abnormalities group (20 cases), combined with intracardiac and extracardiac abnormalities group (37 cases) and only combined with ultrasound soft marker group (20 cases), the last 4 groups were referred as non-simple types. The chromosome test results and pregnancy outcomes of each type and group were analyzed retrospectively. Results: Among the 297 CTD fetuses, the chromosome abnormality rate was 17.5% (52/297). There were 21 cases of abnormal chromosome number, 28 cases of pathogenetic copy number variantions and 3 cases of mosaics. All the 19 cases of micropathogenic fragments smaller than 5 Mb were detected by chromosomal microarray analysis (CMA). Among all the subtypes of CTD, the chromosomal abnormality rate of truncus arteriosus was the highest, at 7/14; while the rate of transposition of the great arteries was the lowest, at 5.2% (4/77). There were significant differences in the rate of chromosomal abnormalities between simple and non-simple types [10.4% (14/134) vs 23.3% (38/163); χ²=8.428, P=0.004]. In each group, the chromosomal abnormality rate was the highest in the combined with intracardiac and extracardiac abnormalities group, at 37.8% (14/37), and the lowest in the simple group, at 10.4% (14/134). There was no significant difference in the rate of chromosomal abnormalities in all subtypes of simple group (all P>0.05). Among 112 cases of live birth, 1 case was 22q11.2 microdeletion syndrome, 5 cases of postnatal clinical diagnosis and prenatal ultrasound diagnosis were not completely consistent, 5 cases died after birth. Conclusions: The incidence of chromosomal abnormalities is high in fetuses with CTD. CTD fetuses with concurrent extrapardiac malformations are more likely to incorporate chromosomal abnormalities. CMA technology could be used as a first-line genetic detection method for CTD. After excluding chromosomal abnormalities, most of the children with CTD have good prognosis.

Abstract
Objective: To investigate the effect of anti-vascular endothelial growth factor (VEGF) therapy on the expression levels of transforming growth factor-beta (TGF-β) and its related microRNAs in the vitreous of patients with proliferative diabetic retinopathy (PDR). Methods: This cross-sectional study included 67 patients (67 eyes), 38 males and 29 females, aged (54.37±11.70) years, who underwent vitrectomy from June 2020 to February 2021. There were 45 PDR patients (45 eyes), including 29 patients (29 eyes) without anti-VEGF therapy in the disease group and 16 patients (16 eyes) who were admitted at 7 days after anti-VEGF therapy in the treatment group. The other 22 idiopathic macular hole patients (22 eyes) were in the negative control group. The microRNA (hsa-miR-24-3p and hsa-miR-197-3p) levels in the vitreous of 36 patients (12 cases randomly chosen from each group) were detected by quantitative reverse transcription polymerase chain reaction. The levels of TGF-β and VEGF-A in the vitreous of 67 patients were detected by enzyme-linked immunosorbent assay. Target gene prediction of hsa-miR-24-3p and hsa-miR-197-3p was performed on RNAhybrid, miRanda and TargetScan7.2 databases, and pathway enrichment analyses were conducted for all target mRNAs. One-way ANOVA was used to compare the levels of growth factors and microRNAs among the three groups, and the least significant difference method was used for multiple comparisons between groups. Pearson correlation test was used to analyze the correlation between growth factors and microRNAs. Results: The expression levels of VEGF-A, TGF-β, hsa-miR-24-3p and hsa-miR-197-3p were (158.15±17.72) pg/ml, (640.47±24.80) pg/ml, 0.81±0.11 and 1.07±0.15 in the control group, (1 047.54±26.61) pg/ml, (3 553.17±92.61) pg/ml, 8.50±2.33 and 12.23±3.38 in the disease group, and (778.10±27.73) pg/ml, (3 376.02±78.83) pg/ml, 4.54±0.67 and 3.90±0.65 in the treatment group, respectively. All indicators were significantly higher in the disease group than those in the control group (F=355.581, 440.538, 7.546 and 7.546; all P<0.05). The expression levels of VEGF-A, hsa-miR-24-3p and hsa-miR-197-3p in the treatment group were significantly lower than those in the disease group (all P<0.05). The concentration of TGF-β was not statistically significantly lower in the treatment group compared to the disease group. The concentrations of VEGF-A and TGF-β were significantly positively correlated with the expression levels of hsa-miR-24-3p and hsa-miR-197-3p in the vitreous of randomly chosen 36 patients (r=0.48, 0.51, 0.40 and 0.42; all P<0.05). Pathway enrichment analysis showed that some target mRNAs of hsa-miR-24-3p and hsa-miR-197-3p were involved in VEGF and TGF-β signal pathways. Conclusions: In the vitreous of patients with PDR, hsa-miR-24-3p and hsa-miR-197-3p were positively related to VEGF-A and TGF-β, and may be potential risk factors. Anti-VEGF treatment can significantly reduce the expression level of TGF-β-related microRNAs, namely hsa-miR-24-3p and hsa-miR-197-3p, but cannot effectively reduce the concentration of TGF-β, suggesting that combined anti-TGF treatment may be beneficial for delaying the progression of PDR. Furthermore, it may be a new research direction of PDR to validate the target mRNAs of hsa-miR-24-3p and hsa-miR-197-3p involved in VEGF and TGF-β signal pathways.

Abstract
TIR (Toll/interleukin-1 receptor/resistance protein) domains are cytoplasmic domains widely found in animals and plants, where they are essential components of the innate immune system. A key feature of TIR-domain function in signaling is weak and transient self-association and association with other TIR domains. An additional new role of TIR domains as catalytic enzymes has been established with the recent discovery of NAD+-nucleosidase activity by several TIR domains, mostly involved in cell-death pathways. Although self-association of TIR domains is necessary in both cases, the functional specificity of TIR domains is related in part to the nature of the TIR : TIR interactions in the respective signalosomes. Here, we review the well-studied TIR domain-containing proteins involved in eukaryotic immunity, focusing on the structures, interactions and their corresponding functional roles. Structurally, the signalosomes fall into two separate groups, the scaffold and enzyme TIR-domain assemblies, both of which feature open-ended complexes with two strands of TIR domains, but differ in the orientation of the two strands. We compare and contrast how TIR domains assemble and signal through distinct scaffolding and enzymatic roles, ultimately leading to distinct cellular innate-immunity and cell-death outcomes.

Abstract
Abstract
Background
The impact of distance from residence to Tertiary Referral Hospital and cardiovascular (CV) outcomes in patients with coronary artery disease (CAD) is unknow. Despite longer travel distances hinder access to healthcare and may worsen CV outcomes, we hypothesize that Mediterranean lifestyle and behaviors in distant rural areas may be associated with a reduced risk of CV death and events.
Purpose
To investigate the association between travel distance to Tertiary Hospital and mid-term cardiovascular outcomes in a population of CAD patients in Southern Spain.
Methods
Retrospective study including all patients discharged after percutaneous coronary intervention (PCI) at a high-volume center in Southern Spain during 2018. Those belonging to another healthcare area were excluded. One-way driving distances from residence to hospital were computed using Google Maps Distance Matrix API with R package “gmapsdistance”. Patients were stratified into tertiles according to travel distance (short, STD; intermediate, ITD; and long, LTD). Kaplan-Meier (KM) and Multivariable Cox regression (adjusted for age, sex, atrial fibrillation, cancer history, prior revascularization and clinical presentation) were used to assess the impact of travel distance on CV death and a composite outcome of MACE (Myocardial Infarction, unplanned PCI and CV death).
Results
Of 1005 patients discharged after PCI during the study period, 966 met the selection criteria. Flowchart and baseline characteristics by distance groups are presented in Figure 1. Median travel distance tertiles were 6.1 (STD), 41.7 (ITD) and 78.4 (LTD). During a median follow-up of 31 (IQR 28–35) months, 50 cardiovascular deaths [STD 27 (8.4%), ITD 13 (4%), LTD 10 (3.1%), p=0.006)] and 63 MACE occurred [STD 45 (13.9%), ITD 37 (11.5%), LTD 26 (8.1%), p=0.060)]. KM curves for the three distance groups are shown in Figure 2. In univariable and multivariable Cox models, longer travel distances were associated with better outcomes, as for every 10 Km increase, there was a 11% and 7% decrease in the hazards of CV death (HR adj: 0.89, CI 0.82–0.98, p=0.029) and of MACE (HR adj: 0.93, CI 0.87–0.99, p=0.025), respectively.
Conclusion
Travel distance was inversely associated with CV events in a population of CAD patients in Southern Spain. Patients in the first tertile of distance had a higher rate of CV death. Multicenter studies involving other Mediterranean regions are needed to confirm these findings and to look for explanations.

Abstract
Abstract
Background
A physiological assessment with the fractional flow reserve (FFR) or instantaneous wave-free ratio (iFR) is strongly recommended by the European Guidelines of Revascularization to guide percutaneous coronary intervention (PCI) decision making in intermediate coronary stenosis. However, data supporting its use in the pro-inflammatory setting of ACS is weak.
Purpose
To analyze the usefulness of a physiological coronary evaluation with iFR of nonculprit lesions in patients with ACS.
Methods
Retrospective multicenter study including patients with ACS and underwent successful revascularization of the culprit vessel and had other nonculpritlesions physiologically evaluated with the iFR between January 2017 and December 2019. The primary endpoint was a composite of cardiac death, nonfatal myocardial infarction, stent thrombosis and new revascularization (MACEs).
Results
A total of 356 patients with 472 nonculprit lesions were included. The mean age was 66±11 years. The clinical presentation was non-ST-segment elevation myocardial infarction (NSTEMI) in 235 patients and ST-segment elevation myocardial infarction (STEMI) in 121 patients. After a mean follow-up period of 22±10 months, the primary endpoint occurred in 32 patients (9%). There were no differences in outcomes regarding iFR induced treatment strategy (patients with all lesions revascularized vs. patients with at least one lesion deferred for revascularization, 10.5 vs 8.4%, p=0.476).
Conclusion
The use of the iFR to guide percutaneous coronary intervention decision making in nonculprit lesions seems to be safe, with an acceptable percentage of MACEs at the mid-term follow-up.

Abstract
Non-small cell lung cancer (NSCLC) is prevalent worldwide and has a high mortality rate. Even if mesenchymal stem cells (MSCs) are suggested as cancer treatment, the studies of their effects on NSCLC cells contradict each other, mainly due to utilization of two-dimensional (2D) culture system. Three-dimensional (3D) culture systems resemble tissue organization in vivo. Here we comprehensively explore the inhibitory effects of MSCs on NSCLC cells in a 3D culture system. We confirmed that the inhibitory effects of 3D-cultured MSCs (3D-MSCs) on the proliferation and migration of NSCLC cells are greater than that of the 2D-cultured MSCs. 3D-MSCs overexpress IL-24, which serve as the key factor enhancing antitumor effects of MSCs. In these cells, IL-24 affects p38 MAPK and CXCR4/AKT pathways. Overall, this study provides the support for use of MSCs in tumor.

Abstract
Objective: To evaluate the value of whole exome sequencing (WES) in prenatal clinical application. Methods: A total of 1 152 cases of congenital abnormal [including structural malformation, nuchal translucency (NT) thickening and intrauterine growth restriction] with traditional prenatal diagnosis [including G-band karyotype analysis and chromosome microarray analysis (CMA)] negative were analyzed. The congenital abnormal fetuses were divided into retrospective group and prospective group according to the time of WES detection, that is whether the pregnancy termination or not. According to the specific location of fetal malformation and their family history, the cohort was divided into subgroups. The clinical prognosis of all fetuses were followed up, and the effect of WES test results on pregnancy decision-making and clinical intervention were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in the third trimester or after birth were re-analyzed. Results: Among 1 152 families who received WES, 5 families were excluded because of nonbiological parents. Among the remaining 1 147 families, 152 fetuses obtained positive diagnosis (13.3%,152/1 147), including 74 fetuses in the retrospective group (16.1%,74/460) and 78 fetuses in the prospective group (11.4%,78/687). In fetuses with negative CMA and G-band karyotype analysis results but new phenotypes in the third trimester or after birth, the positive rate by WES data re-analysis was 4.9% (8/163). A total of 34 (21.3%, 34/160) fetuses were directly affected by the corresponding positive molecular diagnosis. Among 68 cases of live births with diagnostic variation grade 4, 29 cases (42.7%, 29/68) received appropriate medical intervention through rapid review of WES results. Conclusions: WES could increase the detection rate of abnormal fetuses with negative G-banding karyotype analysis and CMA by 13.3%. Prenatal WES could guide pregnancy decision-making and early clinical intervention. It might be an effective strategy to pay attention to the special follow-up of the third trimester and postnatal fetus and to re-analyze the WES data.

Abstract
OBJECTIVES Podocyte pyroptosis, characterized by inflammasome activation, plays an important role in inflammation-mediated diabetic nephropathy (DN). Our study aimed to investigate whether miR-21-5p in macrophage-derived extracellular vesicles (EVs) could affect podocyte injury in DN. METHODS EVs were extracted after the treatment of RAW 264.7 (mouse macrophage line) with high glucose (HG). The podocyte pyroptosis was determined using the flow cytometry and the western blot. After the knockdown of miR-21-5p in HG-induced RAW264.7 cells, we injected the extracted EVs into DN model mice. RESULTS The level of miR-21-5p was higher in HG-stimulated macrophage-derived EVs than in normal glucose-cultured macrophage-derived EVs. The co-culture of EVs and podocytes promoted reactive oxygen species (ROS) production and activation of inflammatory in MPC5 cells (mouse podocyte line). However, restraint of miR-21-5p in EVs reduced ROS production and inhibit inflammasome activation in MPC5 cells, thereby reducing podocytes injury. Meanwhile, we found that miR-21-5p inhibited the A20 expression through binding with its 3'-untranslated regions in MPC5 cells. Further studies showed that A20 was also involved in the regulation of miR-21-5p of RAW 264.7-derived EVs on MPC5 injury. At the same time, it was also proved in the DN model mice that miR-21-5p in macrophage-derived EVs could regulate podocyte injury. CONCLUSION MiR-21-5p in macrophage-derived EVs can regulate pyroptosis-mediated podocyte injury by A20 in DN.

Abstract
PURPOSE An in-depth understanding of the mechanism of thyroid cancer progression will help identify patients with thyroid cancer with a high risk of recurrence and metastasis. Although studies have pointed out that the senescence of thyroid tumor cells may stimulate TAMs and cause a series of changes. However, the role of TAMs in aging thyroid cancer cells is still unknown. The aim of this study was to investigate the function of TAMs in aging thyroid cancer cells. METHODS We conducted in vitro model studies based on the K1 cell line to induce tumor cell senescence and study its effect on the differentiation of macrophages, flow cytometry was used to confirm polarization of macrophages, transwell assay was used to confirm changes of invasion and migration of tumor cells. RESULT Our data indicate that aging thyroid tumor cell lines trigger the polarization of M2-like macrophages, accompanied by increased expression of CCL17, CCL18, IL-18, and TGFβ1. This event is caused by the activation of the NFκB pathway upregulation of CXCL2 and CXCL3 is related. Further studies have shown that differentiated M2-like macrophages promote tumor cell migration (but have no effect on cell proliferation). CONCLUSION Our study indicating that the interaction between tumor and TAMs also occurs in the advanced stages of thyroid tumors and will lead to faster tumors progress.

Abstract
Objective: To investigate the frequency and severity of systemic reactions (SRs) to standardized house dust mite subcutaneous immunotherapy (SCIT) in patients with perennial allergic rhinitis (AR), and to analyze the clinical risk factors. Methods: The clinical data of 362 patients including 209 males and 153 females, aged from 5 to 55 years old receiving SCIT at the Department of Otorhinolaryngology, the Third People's Hospital of Changzhou were collected from May 2014 to July 2017. The SRs were classified as early-onset and delayed-onset, and 4 grades (grade Ⅰ to Ⅳ) to assess severity. The records of SRs were retrospectively analyzed, including the numbers/frequencies, symptoms and signs, onset of reaction and treatment. And the relationships between SRs and patient's age, gender, allergen injection dose, accompanied allergic diseases were explored. All the statistical analyses were conducted using SPSS 19.0. Results: There were 57 cases (15.75%) of SRs in 362 patients. All the patients received a total of 12 308 injections and 111 SRs (0.90%) were observed. Among them, 31 (27.93%) were early-onset reactions and 80 (72.07%) were delayed-onset reactions; most of the SRs were grade Ⅰ reactions (n=83, 74.78%), followed by grade Ⅱ (n=25, 22.52%), grade Ⅲ (n=3, 2.70%), and no fatal reactions occurred. The incidence of SRs in patients>14 years old was higher than that in patients ≤14 years old according to the number of cases and injections (35.14% vs 13.54%, 2.34% vs 0.76%, χ(2) value was 11.679, 28.162, respectively, all P<0.05), but no significant differences of SRs were observed in gender (18.66% vs 11.76%, 5.98% vs 5.62%, χ(2) value was 3.166, 0.095, respectively, all P>0.05). Fifteen SRs (13.51%) occurred during the build-up phase and 96 (86.49%) during the maintenance phases. SRs could occur in lots of dose phases, and 95 (85.59%) were distributed at high concentrations more than 40 000 SQ-U. The incidence of SRs in patients with multiple allergic diseases was significantly higher than that in patients with AR alone, with asthma or atopic dermatitis (30.67% vs 11.85%, χ(2)=15.875, P<0.001). Meanwhile, the incidence of SRs in patients with pure AR was also significantly lower than that in patients with other allergic diseases (5.26% vs 20.56%, χ(2)=13.783, P<0.001). Conclusions: The incidence of SRs is less than 1% according to the injection times, the severity of SRs is mostly slight, and the safety and tolerance are good during standardized house dust mite SCIT in perennial AR patients. Delayed-onset SRs are more common. The incidence of SRs is significantly correlated with age, high dose of allergen vaccine injection, and concomitant other allergic diseases (asthma, atopic dermatitis, etc).

Abstract
β-delayed one-proton emissions of ^{22}Si, the lightest nucleus with an isospin projection T_{z}=-3, are studied with a silicon array surrounded by high-purity germanium detectors. Properties of β-decay branches and the reduced transition probabilities for the transitions to the low-lying states of ^{22}Al are determined. Compared to the mirror β decay of ^{22}O, the largest value of mirror asymmetry in low-lying states by far, with δ=209(96), is found in the transition to the first 1^{+} excited state. Shell-model calculation with isospin-nonconserving forces, including the T=1, J=2, 3 interaction related to the s_{1/2} orbit that introduces explicitly the isospin-symmetry breaking force and describes the loosely bound nature of the wave functions of the s_{1/2} orbit, can reproduce the observed data well and consistently explain the observation that a large δ value occurs for the first but not for the second 1^{+} excited state of ^{22}Al. Our results, while supporting the proton-halo structure in ^{22}Al, might provide another means to identify halo nuclei.

Abstract
OBJECTIVE To investigate the regulatory effects of the Toll-like receptor 4 (TLR4) and the nuclear factor kappa-light-chain-enhancer of the activated B cells (NF-κB) on primary biliary cholangitis (PBC) and to analyze the possible mechanisms. MATERIALS AND METHODS A total of 24 C57BL/6 mice were randomly divided into M group (n=12, intraperitoneally injected with polyinosinic acid-polycytidine acid (PolyI:C) for 12 consecutive weeks, 2 times/week) and C group (n=12, intraperitoneally injected with the same volume of normal saline). After 12 weeks, the mice were sacrificed to collect liver tissues. Then, an enzyme-linked immunosorbent assay (ELISA) kit was used to detect the content of interleukin-6 (IL-6), IL-10, and tumor necrosis factor-alpha (TNF-α) in liver tissues. Hematoxylin-eosin (HE) staining assay was performed to observe the pathological changes of liver tissues, and measure the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in peripheral blood of mice. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end-labeling (TUNEL) staining was applied to determine cell apoptosis in liver tissues. The relative messenger ribonucleic acid (mRNA) expression levels of TLR4 and NF-κB in liver tissues were detected by quantitative Polymerase Chain Reaction (qPCR). Western blotting was adopted to measure the protein expressions of TLR4, NF-κB, myeloid differentiation factor 88 (MyD88), B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein (Bax), and Caspase-3. RESULTS Compared with that in C group, the content of IL-6 and TNF-α in liver tissues in M group was significantly increased (p<0.01), but the level of IL-10 was statistically downregulated (p<0.01). According to HE staining, liver damage of mice in M group was evidently severer than that in C group, and the levels of ALT and AST in M group were significantly higher than those in C group (p<0.01). The amount of TUNEL-positive cells in liver tissues in M group was significantly greater than that in C group (p<0.01). The levels of TLR4 and NF-κB mRNA in liver tissues from M group were significantly elevated in comparison with the C group (p<0.01). Compared with those in C group, the expressions of TLR4, NF-κB, MyD88, and Caspase-3 proteins in M group showed statistical increases in liver tissues (p<0.01), whereas that of Bcl-2/Bax was significantly declined (p<0.01). CONCLUSIONS PBC activates the TLR4/MyD88/NF-κB signaling pathway, induces the release of inflammatory factors and produces a large number of apoptotic proteins, which results in liver damage and cell apoptosis in mice.

Abstract
OBJECTIVE Embryonic stem cells (ESCs) mainly originate from totipotent cells in early-stage of mammalian embryo and could proliferate in a manner of un-limitation. This study aimed to investigate roles of Axin2 in proliferation of ESCs and explore the associated mechanisms. MATERIALS AND METHODS Axis inhibition protein 2 (AXIN2) over-expression (LV5-AXIN2) and AXIN2 RNA interfere (LV3-AXIN2-RNAi) vectors were structured and transfected into H9 cells. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) was used to evaluate cell proliferative activity. Flow cytometry analysis was employed to measure apoptosis of H9 cells. AXIN2, β-catenin, transcription factor 4 (TCF4), c-myc, c-jun and Cyclin D mRNA levels and protein expressions were determined using quantitative real-time PCR (qRT-PCR) and Western blotting assay. RESULTS LV5-AXIN2 and LV3-AXIN2-RNAi were successfully structured with higher transfecting efficacy. AXIN2 gene silencing remarkably increased proliferative activity and AXIN2 treatment significantly induced apoptosis of H9 cells, comparing with blank vector group (p<0.05). AXIN2 gene silencing significantly enhanced B-cell lymphoma-2 (Bcl-2) expression and remarkably inhibited cleaved caspase-3 expression comparing to that in blank vector group (p<0.05). AXIN2-RNAi treatment significantly enhanced and AXIN2 over-expression significantly reduced β-catenin and TCF4 expression, comparing to that in blank vector group (p<0.05). AXIN2 gene silence activated down-stream molecules of Wnt/β-catenin signaling pathway, including c-jun, c-myc, and Cyclin D1 (p<0.05). CONCLUSIONS AXIN2 gene silencing reduced apoptosis by regulating mitochondria-associated apoptosis signaling pathway and enhanced proliferation by modulating molecules in Wnt/β-catenin signaling pathway. Therefore, targeting of aberrant apoptosis and AXIN2 might be a novel clinical strategy to inhibit aging and enhance self-renewal of ESCs.

Abstract
Abstract
Purpose
To analyze the feasibility and efficacy of the jailed pressure wire technique for bifurcation lesions treated by provisional stenting strategy and to assess the physiological side branch (SB) result using instantaneous wave free ratio (iFR).
Methods
Between June 2017 and December 2018, 50 patients who presented a bifurcation lesion considered appropriate for provisional stenting strategy were included in the study. Pressure wire was passed to side branch before treatment. Main vessel (MV) and side branch (SB) was predilated at the operator criteria. iFR determination was obtained in the SB baseline and after MV stenting (leaving the pressure wire jailed). Afterwards, the wire was removed to MV ostium to discard the possibility of drift. SB postdilation was performed if SB iFR was less than 0,89 (according to vessel thresholds established in clinical trials), evaluating the result by a new iFR determination.
Results
The mean age was 64±10 years. Sixteen patients (32%) had diabetes. Clinical presentation was stable angina in 26 patients (52%), non-STEMI in 19 patients (38%) and STEMI (non culprit lesion) in 5 patients (10%). The most frequent bifurcation type according to Medina classifications was 1,1,0 (21 patients, 42%). Seventeen patients (34%) had a true bifurcation lesion. The MV and SB reference diameter was 3,0±0,5 mm and 2,25±0,5 mm respectively. Most of the bifurcations were located at the left anterior descending artery/diagonal branch (27 bifurcations, 54%). Ten patients (20%) presented a distal left main bifurcation. Baseline SB iFR was 0,78±0,2. Under continuous SB iFR monitoring MV stenting was performed by trapping the pressure wire. After MV stenting, the SB iFR changed to 0,90±0,1. We confirmed the presence of drift in 5 patients (10%). In these cases, recalibration of the wire and SB rewiring was performed in 4 cases. In the remaining patient, rewiring was not possible even using specific coronary wires.
According to SB IFR, postdilation was necessary in 14 patients (28%). Final SB iFR was 0,94±0,03. A second stent was not necessary in any patient because final SB iFR was higher than 0.89 in all cases. We observed discordance between angiographic and physiological result in 17 cases (34%). All the wires could be removed. Forty wires (80%) were microscopically analyzed. Some grade of microscopic damage was found in 32 wires (80%), all of them distal to the pressure sensor. However, only one of these wires (2%) presented severe damage, and no case of fracture was observed.
After a mean follow up time of 10±6 months only one patient (2%) presented a major cardiac adverse event (acute coronary syndrome due to voluntary cessation of dual antiplatelet therapy).
Conclusions
The use of jailed pressure wire to monitor SB results for bifurcations treated by provisional stenting seems to be safe. The iFR index seems to provide new physiological information about the significance of the SB stenosis.

Abstract
OBJECTIVE Hepatocellular carcinoma (HCC) is a hypervascularized tumor. Aberrant angiogenesis is the main cause, which results in cancer growth and progression. It has been showed that microRNA-302 cluster (miR-302) may be associated with angiogenesis. Here, we aimed to identify the role of miR-302a/b/c in the regulation of cell angiogenesis in HCC. PATIENTS AND METHODS MRNA expression of miR-302a/b/c and MACC1 was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The protein of MACC1 was measured using Western blot. Cells proliferation, migration, and invasion abilities were investigated via Cell Counting Kit-8 (CCK-8) assay or transwell assay, respectively. Tube formatting assays were used to explore the tube formation capacity. The interaction among miR-302a/b/c was analyzed by luciferase assay. RESULTS The expression of miR-302a/b/c was greatly reduced while MACC1 expression, whether mRNA or protein was conspicuously elevated in HCC tissues and cells. Then, functional experiment results showed miR-302a/b/c overexpression and MACC1 down-regulation inhibited the proliferation, migration, invasion ability, and tube formation capacity of HUVECs. In addition, we detected that miR-302a/b/c directly targeted MACC1 and suppressed MACC1 expression, and miR-302a/b/c could suppress tumor angiogenesis in HCC by targeting MACC1. CONCLUSIONS MiR-302a/b/c may function as a potential suppressor of tumor angiogenesis in HCC by targeting MACC1, indicating a promising target for HCC therapy.

Abstract
Viruses that affect humans, animals and plants are often dispersed and transmitted through airborne routes of infection. Due to current technological deficiencies, accurate determination of the presence of airborne viruses is challenging. This shortcoming limits our ability to evaluate the actual threat arising from inhalation or other relevant contact with aerosolized viruses. To improve our understanding of the mechanisms of airborne transmission of viruses, air sampling technologies that can detect the presence of aerosolized viruses, effectively collect them and maintain their viability, and determine their distribution in aerosol particles, are needed. The latest developments in sampling and detection methodologies for airborne viruses, their limitations, factors that can affect their performance and current research needs, are discussed in this review. Much more work is needed on the establishment of standard air sampling methods and their performance requirements. Sampling devices that can collect a wide size range of virus-containing aerosols and maintain the viability of the collected viruses are needed. Ideally, the devices would be portable and technology-enabled for on-the-spot detection and rapid identification of the viruses. Broad understanding of the airborne transmission of viruses is of seminal importance for the establishment of better infection control strategies.

Abstract
BACKGROUND Bullous pemphigoid (BP) is the most common autoimmune subepidermal blistering skin disease. Two antigens have been identified as targets of circulating autoantibodies (autoAbs) - BP180 and BP230 - with BP180 being a critical transmembrane adhesion protein of basal keratinocytes of the epidermis. The noncollagenous domain 16A (NC16A) of BP180 is the immunodominant epitope in patients with BP, and anti-BP180-NC16A IgG antibodies (Abs) correlate to disease activity. Routine serological testing and follow-up of BP relies on indirect immunofluorescence (IIF) of serum Abs, commonly performed on monkey oesophagus (ME), and/or enzyme-linked immunosorbent assay (ELISA) testing on recombinantly produced fragments of BP180 and BP230 (BP180-NC16A, BP230-C/N). OBJECTIVES To determine if NC16A epitopes are well represented on ME substrate. METHODS Sera from different BP cohorts were tested by IIF on ME and normal human skin (NHS). To confirm findings, affinity-purified anti-BP180-NC16A/BP230 polyclonal Abs and recombinant anti-BP180-NC16A/BP230 monoclonal antibodies (mAbs) were used. RESULTS For sensitive detection of BP180-NC16A-specific IgG Abs, sections of NHS are superior to the widely used ME. Confirmation comes from polyclonal affinity-purified anti-BP180-NC16A/BP230 Abs, and by mAbs cloned from a patient with active BP. CONCLUSIONS Use of NHS is preferable over ME in routine IIF testing for BP. These results are of clinical relevance because anti-BP180-NC16A IgG titres are correlated to disease activity and detecting them reliably is important for screening, diagnosis and follow-up of patients with BP.

Abstract
The CRISPR/Cas9 system is a powerful tool for the treatment of infectious diseases. In our previous study, we knocked out the Bombyx mori nucleopolyhedrovirus (BmNPV) key genes and BmNPV-dependent host factor to generate transgenic antiviral strains. To further expand the range of target genes for BmNPV and more effectively prevent and control pathogenic infections, we performed gene editing and antiviral analysis by constructing a target-directed baculovirus early transcriptional activator immediate early-0 (ie-0) and 2 (ie-2) transgenic silkworm line. We hybridized it with Cas9 transgenic line to produce a double-positive transgenic Cas9(+)/sgIE0-sgIE2(+) line that could activate the CRISPR gene editing system. We first demonstrated that the system is capable of efficiently editing target genes and resulting in fragment deletions in the BmNPV genome. Survival rate of the transgenic Cas9(+)/sgIE0-sgIE2(+) line reached 65% after inoculation with 1 × 106 occlusion bodies/larva. Molecular analysis showed that BmNPV DNA replication and viral gene expression level in the transgenic Cas9(+)/sgIE0-sgIE2(+) line were significantly inhibited compared with the control Cas9(-)/sgIE0-sgIE2(-) line. These results indicated that IE-0 and IE-2, as baculovirus early transcriptional activators, can be used as target sites for gene therapy and that multigene editing could expand the range of target sites for research to create silkworm resistance breeds.

Abstract
OBJECTIVES To investigate the distribution of alleles in 19 autosomal short tandem repeat (STR) loci in Jiangsu Han population. METHODS Goldeneye® 20A kit was used to detect 9 025 samples. Genetic analysis was performed on typing data of 19 autosomal STR loci, and genetic distance with other 17 populations was analyzed. RESULTS All the 19 autosomal STR loci were consistent with the Hardy-Weinberg equilibrium (P>0.05), with the heterozygosity 0.616 1-0.916 3, probability of match 0.012 8-0.202 6, discrimination power 0.797 4-0.987 2, probability of paternity exclusion 0.310 8-0.828 8, and polymorphic information content 0.561 7-0.913 6. The cumulative discrimination power and cumulative probability of exclusion were 0.999 999 999 999 999 998 434 1 and 0.999 999 989, respectively. The Jiangsu Han population had close genetic distances with the Han population in Tianjin, Hunan and Jilin, and significant difference with Han population in Aletai region in Xinjiang (P<0.05). CONCLUSIONS The STR allele polymorphism data and population genetic parameters of Jiangsu Han population can provide data support for the forensic application of these STR loci in Jiangsu Han population.

Abstract
OBJECTIVES To evaluate the diagnostic yield of prenatal whole exome sequencing (WES) for monogenic disorders in fetuses with structural malformations and normal results on cytogenetic testing, and to describe information on pathogenic variants that is provided by WES. METHODS Karyotyping, chromosomal microarray analysis (CMA) and WES were performed sequentially on stored samples from a cohort of 3949 pregnancies with fetal structural abnormalities detected on ultrasound and/or magnetic resonance imaging, referred between January 2011 and December 2015. Diagnostic rates of the three techniques were investigated overall, for phenotypic subgroups and for proband-only vs fetus-mother-father samples. Information on pathogenic variants was identified by WES. RESULTS Overall, 18.2% (720/3949) of fetuses had an abnormal karyotype. Pathogenic copy number variants were detected on CMA in 8.2% (138/1680) of fetuses that had a normal karyotype result. WES performed on a subgroup of 196 fetuses with normal CMA and karyotype results revealed the putative genetic variants responsible for the abnormal phenotypes in 47 cases (24%). The molecular diagnosis rates for fetus-mother-father and proband-only samples were 26.5% (13/49) and 23.1% (34/147), respectively. Variants of uncertain significance were detected in 12.8% (25/196) of fetuses, of which 22 were identified in the fetal proband-only group (15%; 22/147) and three in the fetus-mother-father group (6.1%; 3/49). The incidental finding rate was 6.1% (12/196). CONCLUSIONS WES is a promising method for the identification of genetic variants that cause structural abnormalities in fetuses with normal results on karyotyping and CMA. This enhanced diagnostic yield has the potential to improve the clinical management of pregnancies and to inform better the reproductive decisions of affected families. Copyright © 2017 ISUOG.

Abstract
OBJECTIVES To investigate the genetic information of 30 insertion/deletion (InDel) loci in Han population from Jiangsu Province, and to explore the application values of Investigator® DIPplex kit for guiding the forensic analysis in Han population from Jiangsu Province. METHODS The autosomal InDel loci of 305 unrelated healthy Han individuals from Jiangsu Province were genotyped and analysed by Investigator® DIPplex kit, and the allelic frequencies and forensic parameters of 30 InDel loci were statistically analysed. RESULTS The distribution of 30 InDel loci in Han population from Jiangsu Province conformed to Hardy-Weinberg equilibrium. The minor allele frequencies of 21 InDel loci were above 0.3. The polymorphism information content ranged from 0.089 to 0.375, while the discrimination power distributed from 0.093 to 0.500. The paternity exclusion in duo cases and trio cases were 0.047-0.250 and 0.046-0.219, respectively. The linkage disequilibrium analysis of 30 InDel loci showed that all loci were independent from each other. The combined discrimination power was 1-7.369×10⁻⁸, whereas the combined mean exclusion chance in duo cases was 0.998 933 978, in trio cases was 0.997 806 392. The Fst values were all less than 0.06 except HLD118 and other four loci, which showed small differences between groups. CONCLUSIONS The InDel loci of Investigator® DIPplex kit can be used as complementary genetic markers for the cases associated with forensic genetics.
