Abstract
BACKGROUND Live attenuated vaccines alter immune functions and are associated with beneficial outcomes. We previously demonstrated that live attenuated yellow fever virus (YFV) vaccine (LA-YF-Vax) dampens T-cell receptor (TCR) signaling in vitro via an RNA-based mechanism. We examined study participants before and after LA-YF-Vax to assess TCR-mediated functions in vivo. METHODS Serum samples and peripheral blood mononuclear cells (PBMCs) were obtained before and after LA-YF-Vax (with or without additional vaccines) or quadrivalent influenza vaccine. TCR-mediated activation was determined by interleukin 2 release or phosphorylation of the lymphocyte-specific Src kinase. TCR-regulating phosphatase (protein tyrosine phosphatase receptor type E [PTPRE]) expression was also measured. RESULTS Compared with prevaccination findings, LA-YF-Vax recipient PBMCs demonstrated transient reduction in interleukin 2 release after TCR stimulation and PTPRE levels, unlike in control participants who received quadrivalent influenza vaccine. YFV was detected in 8 of 14 participants after LA-YF-Vax. After incubation of healthy donor PBMCs in serum-derived extracellular vesicles prepared from LA-YF-Vax recipients, TCR signaling and PTPRE levels were reduced after vaccination, even in participants without detectable YFV RNA. CONCLUSIONS LA-YF-Vax reduces TCR functions and PTPRE levels after vaccination. Extracellular vesicles from serum recapitulated this effect in healthy cells. This likely contributes to the reduced immunogenicity for heterologous vaccines after LA-YF-Vax administration. Identification of specific immune mechanisms related to vaccines should contribute to understanding of the "off-target," beneficial effects of live vaccines.

Abstract
Objective: To investigate the efficacy of pars plana vitrectomy (PPV) without intraocular tamponade in the treatment of high myopic eyes with myopic foveoschisis (MF) accompanied by foveal detachment (FD). Methods: A retrospective case series study was conducted. The medical records of patients diagnosed with unilateral MF accompanied by FD at the Eye & ENT Hospital of Fudan University between May 2018 and December 2021 were collected. All patients underwent 23-gauge PPV with posterior vitreous cortex clearance, and no intraocular tamponade was applied. The cases were divided into groups based on whether the internal limiting membrane was peeled during surgery or retained. Follow-up was conducted for at least 12 months. The main outcome measures included postoperative best-corrected visual acuity (BCVA, converted to logarithm of the minimum angle of resolution), central foveal thickness (CFT), MF resolution, and complications. Statistical analyses were performed using t-tests, chi-square tests, Fisher's exact tests, and univariate and multivariate linear regression. Results: A total of 40 patients (40 eyes) with MF and FD were included in the study, with 30.0% being male and 70.0% female. The mean age was (56.9±11.7) years, and the axial length of the eyes was (29.1±1.9) mm. At 12 months postoperatively, BCVA improved from baseline 1.15±0.58 to 0.73±0.39 (t=6.11, P<0.001), and CFT decreased from baseline (610.1±207.2) μm to (155.9±104.1) μm (t=13.47, P<0.001). Complete resolution of MF with foveal reattachment was observed in 80.0% of eyes, with a median time of 6 (5, 8) months. There was no significant difference in BCVA and CFT between the internal limiting membrane peeled group and retained group [0.68±0.39 vs. 0.79±0.40, t=0.85, P=0.403; (148.3±63.8)vs.(164.3±137.2)um,t=0.48, P=0.634]. One eye experienced macular hole and another eye developed retinal detachment postoperatively. Correlation analysis showed a positive correlation between BCVA at 12 months postoperatively and baseline BCVA (β=0.433, P<0.001). Conclusions: Pars plana vitrectomy without intraocular tamponade is effective in treating MF accompanied by FD. The choice between internal limiting membrane peeling and retention does not significantly affect visual prognosis.

Abstract
OBJECTIVES To investigate the diagnostic value of measuring the talofibular space using stress sonography for chronic lateral ankle instability (CLAI). MATERIALS & METHODS We recruited patients who were clinically diagnosed with CLAI between October 2018 and December 2019 (CLAI group). A control group of healthy volunteers was also included for this study. Both groups underwent a preliminary stress sonographic examination. First, the ultrasonic characteristics of the anterior talofibular ligament (ATFL), including length, thickness, relaxation, calcification, and rupture, were observed using conventional sonography. Second, the talofibular space at the passive neutral position (D1) and maximum varus position (D2) was measured (by stress sonographic images), and the difference (ΔD = D1-D2) between them was determined. Third, the parameters of the two groups were statistically compared. Finally, receiver operating characteristic (ROC) curves and area under the curve (AUC) analyses were performed for parameters with significant differences. RESULTS The CLAI group comprised 60 patients, yielding data on 60 ankles, whereas the control group comprised 35 participants, yielding data for 70 ankles. Differences in D1, D2, and ΔD of the talofibular space between the two groups were significant, with ΔD proving to be the best diagnostic indicator (P < 0.001). Its AUC, optimal cutoff value, sensitivity, and specificity were 0.922, 0.11 cm, 73 %, and 94 %, respectively, followed by D2 (0.850, 0.47 cm, 67 %, and 94 %, respectively; P < 0.001) and D1 (0.635, 0.47 cm, 67 %, and 94 %, respectively; P = 0.006). CONCLUSION Measurement of talofibular space in stress sonography is a valuable diagnostic indicator for CLAI, especially the ΔD between the neutral and stress position.

Abstract
BACKGROUND The immunity of patients with lung cancer decreases after treatment; thus, they are easily infected with pathogenic bacteria that causes pulmonary infections. Understanding the distribution characteristics of pathogenic bacteria in pulmonary infection in patients with lung cancer after treatment can provide a basis to effectively prevent infection and rationally use antibacterial drugs. However, no meta-analyses have assessed the distribution characteristics of pathogenic bacteria in mainland China. Therefore, our meta-analysis aimed to investigate the pathogen distribution in pulmonary infection in Chinese patients with lung cancer. METHODS A literature search was conducted to study the pathogen distribution in pulmonary infection in Chinese patients with lung cancer between January 1, 2020 and December 31, 2022, using English and Chinese databases. The relevant data were extracted. The meta-analysis was performed using a random-effects model ( I2 > 50%) with 95% confidence intervals for forest plots. Data were processed using RevMan 5.3. RESULTS Fifteen studies (2,683 strains in 2,129 patients with pulmonary infection were cultured) met the evaluation criteria. The results showed that Gram-negative bacteria had the highest detection rate (63%), followed by Gram-positive bacteria (23%), and fungi (12%). Among the Gram-negative bacteria detected, the distribution of the main pathogenic bacteria was Klebsiella pneumonia (17%), Pseudomonas aeruginosa (14%), Escherichia coli (13%), Acinetobacter baumannii (7%), Enterobacter cloacae (4%), and Hemophilus influenza (4%). Moreover, the prevalence of pulmonary infections after chemotherapy (53%) was significantly higher than that after surgery (10%), P < 0.05. CONCLUSIONS The prevalence of pulmonary infections after treatment, especially after chemotherapy, is high in Chinese patients with lung cancer, and Gram-negative bacteria are the predominant pathogens. Further studies are needed to monitor the prevalence of pulmonary infections and pathogen distribution in lung cancer patients in mainland China.

Abstract
Some major challenges of ovarian tissue vitrification and transplantation include follicle apoptosis induced by cryopreservation and ischemia-reperfusion injury, as well as ovarian follicle loss during post-transplantation. This research aimed to investigate the protective effects and underlying mechanisms of follicle-stimulating hormone (FSH) and Sphingosine-1-phosphate (S1P) on vitrified and post-transplantation ovaries. Ovaries from 21-day-old mice were cryopreservation by vitrification with 0.3 IU/mL FSH, 2 µM S1P, and 0.3 IU/mL FSH + 2 µM S1P, respectively, for follicle counting and detection of apoptosis-related indicators. The results demonstrated that FSH and S1P co-intervention during the vitrification process could preserve the primordial follicle pool and inhibit follicular atresia by suppressing cell apoptosis. The thawed ovaries were transplanted under the renal capsule of 6-8 week-old ovariectomized mice and removed 24 h or 7 days after transplantation. The results indicated that FSH and S1P co-intervention can inhibit apoptosis and autophagy in ovaries at 24 h after transplantation, and promote follicle survival by up-regulating Cx37 and Cx43 expression, enhanced angiogenesis in transplanted ovaries by promoting VEGF expression, as well as increased the E2 levels to restore ovarian endocrine function at 7 days after transplantation. The hypoxia and ischemia cell model was established by CoCl2 treatment for hypoxia in human granulosa-like tumor cell line (KGN), as well as serum-free culture system was used for ischemia. The results confirmed that ischemia-hypoxia-induced apoptosis in ovarian granulosa cells was reduced by FSH and S1P co-intervention, and granulosa cell autophagy was inhibited by up-regulating the AKT/mTOR signaling pathway. In summary, co-administration of FSH and S1P can maintain ovarian survival during ovarian vitrification and increase follicle survival and angiogenesis after transplantation.

Abstract
The formation of the Ontong Java Nui super oceanic plateau (OJN), which is based on the model that the submarine Ontong Java Plateau (OJP), Manihiki Plateau (MP), and Hikurangi Plateau (HP) were once its contiguous fragments, could have been the largest globally consequential volcanic event in Earth's history. This OJN hypothesis has been debated given the paucity of evidence, for example, the differences in crustal thickness, the compositional gap between MP and OJP basalts and the apparent older age of both plateaus relative to HP remain unresolved. Here we investigate the geochemical and 40Ar-39Ar ages of dredged rocks recovered from the OJP's eastern margin. Volcanic rocks having compositions that match the low-Ti MP basalts are reported for the first time on the OJP and new ~ 96-116 Ma and 67-68 Ma 40Ar-39Ar age data bridge the temporal gap between OJP and HP. These results provide new evidence for the Ontong Java Nui hypothesis and a framework for an integrated tectonomagmatic evolution of the OJP, MP, and HP. The isotopic data imply four mantle components in the source of OJN that are also expressed in present-day Pacific hotspots sources, indicating origin from (and longevity of) the Pacific Large Low Shear-wave Velocity Province.

Abstract
Plant cells recognize microbial patterns with the plasma-membrane-localized pattern-recognition receptors consisting mainly of receptor kinases (RKs) and receptor-like proteins (RLPs). RKs, such as bacterial flagellin receptor FLS2, and their downstream signaling components have been studied extensively. However, newly discovered regulatory components of RLP-mediated immune signaling, such as the nlp20 receptor RLP23, await identification. Unlike RKs, RLPs lack a cytoplasmic kinase domain, instead recruiting the receptor-like kinases (RLKs) BAK1 and SOBIR1. SOBIR1 specifically works as an adapter for RLP-mediated immunity. To identify new regulators of RLP-mediated signaling, we looked for SOBIR1-binding proteins (SBPs) in Arabidopsis thaliana using protein immunoprecipitation and mass spectrometry, identifying two G-type lectin RLKs, SBP1 and SBP2, that physically interacted with SOBIR1. SBP1 and SBP2 showed high sequence similarity, were tandemly repeated on chromosome 4, and also interacted with both RLP23 and BAK1. sbp1 sbp2 double mutants obtained via CRISPR-Cas9 gene editing showed severely impaired nlp20-induced reactive oxygen species burst, mitogen-activated protein kinase (MAPK) activation, and defense gene expression, but normal flg22-induced immune responses. We showed that SBP1 regulated nlp20-induced immunity in a kinase activity-independent manner. Furthermore, the nlp20-induced the RLP23-BAK1 interaction, although not the flg22-induced FLS2-BAK1 interaction, was significantly reduced in sbp1 sbp2. This study identified SBPs as new regulatory components in RLP23 receptor complex that may specifically modulate RLP23-mediated immunity by positively regulating the interaction between the RLP23 receptor and the BAK1 co-receptor.

Abstract
Background Oral microbiota is closely related to the homeostasis of the oral cavity and lungs. To provide potential information for the prediction, screening, and treatment strategies of individuals, this study compared and investigated the bacterial signatures in periodontitis and chronic obstructive pulmonary disease (COPD). Materials and methods We collected subgingival plaque and gingival crevicular fluid samples from 112 individuals (31 healthy controls, 24 patients with periodontitis, 28 patients with COPD, and 29 patients with both periodontitis and COPD). The oral microbiota was analyzed using 16S rRNA gene sequencing and diversity and functional prediction analysis were performed. Results We observed higher bacterial richness in individuals with periodontitis in both types of oral samples. Using LEfSe and DESeq2 analyses, we found differentially abundant genera that may be potential biomarkers for each group. Mogibacterium is the predominant genus in COPD. Ten genera, including Desulfovibrio, Filifactor, Fretibacterium, Moraxella, Odoribacter, Pseudoramibacter Pyramidobacter, Scardovia, Shuttleworthia and Treponema were predominant in periodontitis. Bergeyella, Lautropia, Rothia, Propionibacterium and Cardiobacterium were the signature of the healthy controls. The significantly different pathways in the Kyoto Encyclopedia of Genes and Genomes (KEGG) between healthy controls and other groups were concentrated in genetic information processing, translation, replication and repair, and metabolism of cofactors and vitamins. Conclusions We found the significant differences in the bacterial community and functional characterization of oral microbiota in periodontitis, COPD and comorbid diseases. Compared to gingival crevicular fluid, subgingival plaque may be more appropriate for reflecting the difference of subgingival microbiota in periodontitis patients with COPD. These results may provide potentials for predicting, screening, and treatment strategies for individuals with periodontitis and COPD.

Abstract
Acoustic levitation is an important method of container-free processing, which counteracts gravity through exerting the acoustic radiation force on levitated objects. The Gorkov potential function is used to simplify the calculation of the acoustic radiation force acting on a Rayleigh sphere whose radius is much smaller than the wave length. For the case of a plane standing wave levitation system, a systematic analysis of the sphere dynamics is provided in the axial direction, assuming a small perturbation around the stable equilibrium locations. A generalized extension to an arbitrary standing wave field is provided, which gives formal expressions of the axial and transverse natural oscillation frequencies for the sphere. Particular emphasis is put on the natural oscillation frequencies with and without taking gravity into consideration. The computational results for Gauss and Bessel standing waves are provided as two special cases, which show that the transverse natural oscillation frequency will be overestimated when neglecting gravity, especially for a sphere with a relatively large density. Corresponding experiments are conducted to verify the dependence of the transverse natural oscillation frequency on the sphere density. The results obtained in this work are expected to provide a theoretical guide for enhancing the levitation stability and inversing the physical parameters from the sphere dynamics.

Abstract
Objective: To explore the effect of neoadjuvant immunotherapy on pulmonary function and the efficacy in patients with resectable non-small cell lung cancer. Methods: Data of 30 patients with non-small cell lung cancer (NSCLC) who received neoadjuvant immunotherapy before surgery in the Chest Hospital of Shanghai Jiaotong University from March 2018 to September 2021 were retrospectively collect. The efficacy and safety of neoadjuvant immunotherapy in the perioperative period and changes in pulmonary function of patients before and after neoadjuvant treatment were valuated. Results: The patients were all-male with age of (61±8)years old, The major pathological response (MPR) rate of patients receiving neoadjuvant immunotherapy was 43%(13 cases), the pathologic complete response (pCR) rate was 37% (11 cases), disease control rate (DCR) was 97% (29 cases), objective response rate (ORR) was 67% (20 cases). The forced expiratory volume in one second (FEV1) after treatment was (2.59±0.63) L, and the ratio of FEV1 to the predicted value (FEV1%pred) was 85.27%±15.86%, which were significantly higher than those before treatment [(2.48±0.59)L, 81.73%±15.94%, respectively] (P=0.013, 0.022, respectively). Forced vital capacity (FVC) after treatment was (3.59±0.77) L, which was also significantly higher than before [(3.47±0.76) L,P=0.036]; while there were no statistical difference in FEV1/FVC and FVC accounted for the proportion of predicted values (FVC%pred) between before and after treatment (P=0.084, 0.344, respectively). The ratio of carbon monoxide dispersion (DLCO) to the predicted value (DLCO%pred) decreased from 83.61%±13.10% to 78.69%±13.85% after treatment (P=0.023). There was no significant difference in the incidence of postoperative complications between the DLCO%pred decreased group and the non-decreased group (3/18 vs 0/6; P=0.546). Conclusions: Neoadjuvant immunotherapy can increase the rate of MPR and PCR, significantly increase FEV1 and FEV1%pred, but also lead to a decrease in DLCO%pred; neoadjuvant immunotherapy does not increase the incidence of postoperative complications.

Abstract
BACKGROUND This study aimed to evaluate the correlation and consistency between traditional head measurement and structured light three-dimensional (3D) scanning parameters when measuring infant skull shape. METHODS A total of 76 infants aged 3 months to 2.5 years old were included in the study. Head circumference (HC) was measured with a tape measure. The transverse, anteroposterior, and oblique diameters were measured using a spreading caliper, and the cranial vault asymmetry index (CVAI) and a cranial index (CI) of symmetry were calculated; 76 cases were measured successfully. The above indexes were measured using a structured light 3D scanning system (71 cases were measured with success). Thus, in the end, the valid data of 71 cases were analyzed, and the measurements of the two approaches were compared. RESULTS The 95% confidence interval of traditional head measurement and structured light 3D scanning was between 0.633 and 0.988. Pearson's correlation coefficient indicated a high correlation between the two methods (r=0.793-0.980). The correlation coefficients of the transverse diameter, anteroposterior diameter, and HC, and the CI of symmetry were higher than 0.9. The lowest correlation coefficient for the CVAI was 0.793. The P values of the above measurement data were all <0.001, which indicated that they were closely related. A Bland-Altman plot indicated reasonable consistency between the two methods. CONCLUSIONS Both traditional head measurement and structured light 3D scanning are suitable for the measurement of infant head shape. However, while traditional head measurement using a spreading caliper is economical and simple, making it suitable for general screening at a basic level, structured light 3D scanning can deliver additional parameters, which is useful for infants with an abnormal head shape. The latter is also convenient for designing a customized helmet for skull correction when needed.

Abstract
Abstract
Introduction/Objective
NUT carcinoma (NC) is an extremely rare, aggressive subtype of squamous cell carcinoma defined by rearrangement of the NUTM1 (aka NUT) gene. NC most commonly arises within the thorax and head and neck and predominantly affects teens and young adults. For the first time, we described a rare case of NC mimics anaplastic thyroid carcinoma.
Methods/Case Report
A 27-year female with no significant past medical history presented with neck pain and swelling for a few months and was noted to have a “thyroid” mass. An ultrasound guided fine needle aspiration of the mass showed a hypercellular specimen composed of highly atypical epithelial cells with irregular nuclear membrane and prominent nucleolus, high nuclear to cytoplasmic ration, dense cytoplasm, lying singly or in flat sheet mixed with acute inflammatory exudate (Fig. A, B). No thyroid follicular cells or colloid are present. It was signed out as suspicious for squamous cell carcinoma since there was no cell block for further workup. A following excisional biopsy demonstrated similar atypical epithelium detached or embedded in skeletal muscle and soft tissue with acute, chronic inflammation and necrosis (Fig C). By immunohistochemical stains, the atypical cells are positive for p40 (Fig D) and p53. The Ki-67 proliferation index is ranging from 40 % to 70 %. Scattered tumor cells are weakly positive for PAX-8 and TTF-1. These findings raise the possibility that the squamous cell carcinoma might be a component of anaplastic thyroid carcinoma. However, molecular studies revealed a NSD3-NUTM1 fusion, which is characteristically identified in a subtype of squamous cell carcinoma know as NUT “midline” carcinoma.
Results (if a Case Study enter NA)
NA
Conclusion
Diagnosis of NC can be established by positive NUT nuclear immunohistochemical staining. Recognizing the typical morphology and keeping low threshold for the NUT immunohistochemical staining will increase the diagnostic efficacy.

Abstract
Receptor-like cytoplasmic kinase subfamily VII (RLCK-VII) proteins are the central immune kinases in plant pattern-recognition receptor (PRR) complexes, and they orchestrate a complex array of defense responses against bacterial and fungal pathogens. However, the role of RLCK-VII in plant-oomycete pathogen interactions has not been established. Phytophthora capsici is a notorious oomycete pathogen that infects many agriculturally important vegetables. Here, we report the identification of RXLR25, an RXLR effector that is required for the virulence of P. capsici. In planta expression of RXLR25 significantly enhanced plants' susceptibility to Phytophthora pathogens. Microbial pattern-induced immune activation in Arabidopsis was severely impaired by RXLR25. We further showed that RXLR25 interacts with RLCK-VII proteins. Using nine rlck-vii high-order mutants, we observed that RLCK-VII-6 and RLCK-VII-8 members are required for resistance to P. capsici. The RLCK-VII-6 members are specifically required for Phytophthora culture filtrate (CF)-induced immune responses. RXLR25 directly targets RLCK-VII proteins such as BIK1, PBL8, and PBL17 and inhibits pattern-induced phosphorylation of RLCK-VIIs to suppress downstream immune responses. This study identified a key virulence factor for P. capsici, and the results revealed the importance of RLCK-VII proteins in plant-oomycete interactions.

Abstract
BACKGROUND Although rarely indicated, antibiotics are commonly used for acute diarrhoea in China. We conducted a randomised, double blind exploratory clinical trial of loperamide, berberine and turmeric for treatment of acute diarrhoea. METHODS Adults with acute uncomplicated diarrhoea aged 18 to 70 were randomised to 4 groups: (A) loperamide; (B) loperamide and berberine; (C) loperamide and turmeric; (D) loperamide, berberine and turmeric. All participants were given rescue ciprofloxacin for use after 48 h if symptoms worsened or were unimproved. Primary endpoints were feasibility and ciprofloxacin use during the 2-week follow-up period. Semi-structured interviews were conducted following recruitment and were analysed thematically. Recruiting doctors, delivery pharmacists and research assistants were blinded to treatment allocation. RESULTS Only 21.5% (278/1295) of patients screened were deemed eligible, and 49% (136/278) of these consented and were entered into the final analysis. Most participants had mild symptoms, because most patients with moderate or severe symptoms wanted to be given antibiotics. Follow-up was good (94% at 2 weeks). Only three participants used rescue antibiotics compared to 67% of acute diarrhoea patients in the hospital during the recruitment period. The median symptom duration was 14 h in group B (interquartile range (IQR) 10-22), 16 h in group D (IQR 10-22), 18 h in group A (IQR 10-33) and 20 h in group C (IQR 16-54). Re-consultation rates were low. There were no serious treatment-related adverse events. Most interviewed participants said that although they had believed antibiotics to be effective for diarrhoea, they were surprised by their quick recovery without antibiotics in this trial. CONCLUSION Although recruitment was challenging because of widespread expectations for antibiotics, patients with mild diarrhoea accepted trying an alternative. The three nutraceuticals therapy require further evaluation in a fully powered, randomised controlled trial among a broader sample. TRIAL REGISTRATION ChiCTR-IPR-17014107.

Abstract
Background: TGF-β1 is a key cytokine involved in both airway inflammation and airway remodeling in asthma because of its anti-inflammatory and profibrotic effect. In our previous study, we found that knockdown of cytosolic β-catenin alleviated the profibrogenic effect of TGF-β1 without influencing its anti-inflammatory effect. However, the exact role of targeting β-catenin in asthma is not yet fully demonstrated. In the present study, we investigated the effect and mechanism of targeting β-catenin in OVA-challenged asthmatic rats with airway inflammation and remodeling features. Methods: We integrated experimental asthma model and asthma related cell model to explore the effect of targeting β-catenin on airway inflammation and remodeling of asthma. Results: Blocking β-catenin with ICG001, a small molecule inhibitor of β-catenin/TCF via binding to cAMP-response elementbinding protein, attenuated airway inflammation by increasing levels of anti-inflammation cytokines IL-10, IL-35 and decreasing levels of T helper (Th)2 cells and Th17 cytokine. Suppressing β-catenin by ICG001 inhibited airway remodeling via reducing the level of TGF-β1 and the expressions of Snail, MMP-7, MMP-9 and, up-regulating expression of E-cadherin, down-regulating expressions of α-SMA and Fn. Inhibition of β-catenin with ICG001 suppressed TGF-β1 induced proliferation and activation of CCC-REPF-1, blocked TGF-β1 induced epithelial–mesenchymal transition (EMT) of RLE-6TN. Conclusion: Blockade of β-catenin/TCF not only prevents TGF-β1 induced EMT and profibrogenic effects involved in pathological remodeling of airway, but also alleviates airway inflammation in asthma by balancing pro-inflammatory and anti-inflammatory cytokine. In conclusion, targeting β-catenin specifically via inhibition of β-catenin/TCF might be a new therapeutic strategy for asthma.

Abstract
Background Positional head deformity (PHD) is defined as a change in the shape of an infant’s skull due to an external force. In certain cases, it can lead to cosmetic deformities or even neurological issues due to its impact on the developing nervous system. Therefore, we conducted this study to investigate the incidence and characteristics of PHD in term infants in China and preliminarily establish a localized diagnostic reference standard. Methods Overall, 4456 term infants from three medical institutions in Chongqing were and divided and analyzed according to their age. Cranial vault asymmetry (CVA) and cephalic index (CI) were calculated in all infants. The current international diagnostic criteria were used to understand PHD incidence and analyze the CVA and CI distribution. Results According to the current international standards, the total detection rate of PHD in Chongqing’s term infants was 81.5%, with brachycephaly alone being the most frequent (39.4%), followed by brachycephaly with plagiocephaly (34.8%) and plagiocephaly alone (6.2%). The detection rates of dolichocephaly were low: alone, 0.9% and combined with plagiocephaly, 0.2%. According to age, plagiocephaly (44.5%) and brachycephaly (82.0%) were the most frequent in the 2-3-month group. The 75th/90th/97th and 3rd/10th/25th/75th/90th/97th percentiles of CVA and CIs were 0.4/0.7/1.0 and 76.4/78.8/82.3/91.1/94.6/99.2%, respectively. Conclusions According to the current international standards, the PHD detection rate among term infants in Chongqing was high. Therefore, a new diagnostic standard for Chinese infants was proposed where CVA ≥ 0.4 cm indicates plagiocephaly, CI ≥ 91% indicates brachycephaly, and CI ≤ 82% indicates dolichocephaly.

Abstract
BACKGROUND Different from the traditional right ventricular pacing, the left bundle branch area pacing (LBBAP) is accomplished with deeper lead implantation and more attempts. However, myocardial damage is unclear in LBBAP. OBJECTIVE The objective of the study was to observe the change of troponin T and explore possible factors associated with greater myocardial damage in LBBAP. METHODS Patients with an indication for pacemaker implantation underwent attempts for LBBAP by transventricular septal method. Levels of troponin T were determined before operation, 12 h and 1 week after the operation. Parameters of intraoperation and follow-up were recorded and analyzed. RESULTS In total, successful LBBAP was achieved in 126 patients. The levels of troponin T increased significantly at 12 h after the operation compared with those before operation (96.45 ± 11.07 [69.06] vs. 16.59 ± 1.84 [11.92] ng/L, p < 0.001), while there were no significant differences between pre- and post-operative levels at 1 week. Correlation and regression analysis showed that only the number of attempts was an independent factor related to the change of troponin T. During 1 year of follow-up, LBBAP was safe and feasible with few complications. CONCLUSIONS Myocardial damage of LBBAP was clinically significant. The number of attempts was an independent factor related to the myocardial damage.

Abstract
AIM Abdominal aortic aneurysm (AAA) is characterized by macrophage polarization, and at present, no drug therapy is available. Although grape-seed polyphenols (GSP) showed an anti-AAA effect, the role of GSP in the phenotype shift in macrophages remains unknown. METHOD The main phenolic compounds in GSP were determined by LC-MS. Male C57BL/6 mice were divided into four equal groups, namely sham group, CaPO4 group, CaPO4+GSP low-dose group, and CaPO4+GSP high-dose group. GSP was administered intragastrically after CaPO4 application. Molecular expressions were histologically evaluated and analyzed by various staining assays and FACS. RESULTS GSP administration inhibited CaPO4-induced AAA formation, which correlated with a decrease in macrophage infiltration and retainment of vascular smooth muscle layer as compared to those in the CaPO4 group. FACS assay showed that the GSP administration dose-dependently decreased the CD54 expression (low-dose group: 11.4 ± 2.1 % and high-dose group: 4.8 ± 1.4 % vs 23.2 ± 3.6 %; p < 0.05 and p < 0.01, respectively) and increased the CD206 expression of F4/80-positive cells in GSP-administered groups as compared with that in CaPO4-injured aortas in the CaPO4 group (low-dose group: 22.4 ± 3.3 % and high-dose group: 26.7 ± 4.2 % vs 8.1 ± 1.3 %; p < 0.05 and p < 0.01, respectively). CONCLUSIONS GSP could be a pharmacologically potent agent in the treatment of AAA (Tab. 1, Fig. 3,Ref. 20).

Abstract
Pleistocene climatic fluctuations may have had a profound impact on the evolutionary history of many species. The geographical pattern of European wild boar (Sus scrofa) is clearly studied, and it was greatly influenced by ancient climatic events, especially the Last Glacial Maximum. Previous research on genetic variation has mainly focused on the origin and distribution histories of domestic pigs. However, some questions have not been answered, including those concerning the genetic diversity, geographical pattern and possible historic influence of climate on East Asian wild boar (EAWB). Employing the control region of mtDNA (511 bp), we investigated the contributions of historic climate, which possibly shaped the genetic pattern of wild boar. Given that the level of genetic diversity of wild boars is higher in East Asia than in Europe, 172 haplotypes were detected from 680 individuals. Phylogenetic analysis demonstrated the complex phylogeographic structure of EAWB. Mismatch analysis, neutrality tests and the Bayesian Skyline Plot results all retrieved signals of a rapid population expansion, which might have played an important role in driving the formation of complex spatial genetic structure. Genetic data and species distribution modelling showed that the Last Glacial Maximum had weak effect on the distribution of the EAWB. We suggest that, in shaping spatial genetic structure in East Asian, long-term gene flow and population history played more important roles than Pleistocene climate fluctuations.

Abstract
We propose three different methods to determine the optimal number of hidden nodes based on L1 regularization for a multilayer perceptron network. The first two methods, respectively, use a set of multiplier functions and multipliers for the hidden-layer nodes and implement the L1 regularization on those, while the third method equipped with the same multipliers uses a smoothing approximation of the L1 regularization. Each of these methods begins with a given number of hidden nodes, then the network is trained to obtain an optimal architecture discarding redundant hidden nodes using the multiplier functions or multipliers. A simple and generic method, namely, the matrix-based convergence proving method (MCPM), is introduced to prove the weak and strong convergence of the presented smoothing algorithms. The performance of the three pruning methods has been tested on 11 different classification datasets. The results demonstrate the efficient pruning abilities and competitive generalization by the proposed methods. The theoretical results are also validated by the results.

Abstract
White matter injury caused by perinatal hypoxia-ischemia is characterized by myelination disorders; however, its pathophysiological mechanisms are not fully elucidated. The neurofascin 155 (NF155) protein, expressed in oligodendrocytes, is critical for myelination. Previous findings suggest that NF155 participates in the pathological mechanisms of developmental myelination disorders in hypoxic-ischemic cerebral white matter lesions, and it might regulate cytoskeletal changes. Therefore, we hypothesized that increased NF155 expression during the early stages of hypoxic oligodendrocyte injury helps normalize myelin sheath development and consequently improves neural function by repairing paranodal structures of myelin sheaths and regulating cytoskeletal changes. To test this hypothesis, we established a hypoxic-ischemic, mixed neonatal rat forebrain cell culture model. When NF155 expression was upregulated, synergistic effects occurred between this protein and the paranodal proteins CASPR and contactin. In addition, the expression of Rho GTPase family proteins that regulate key cytoskeletal pathways, myelin sheath structures, and functions were restored, and axonal structures acquired a clear and transparent appearance. These results suggest that NF155 may enable myelin sheath repair by repairing paranodal region structures and regulating oligodendrocyte cytoskeletal mechanisms. Overall, the present study provides new insights into the pathogenesis of hypoxic-ischemic cerebral white matter lesions.

Abstract
We previously reported the presence of vasculogenic mimicry (VM) in human osteosarcoma. However, the mechanistic basis of osteosarcoma VM remains unclear. Three hundred eighty-one upregulated differentially expressed genes (DEGs) and 526 downregulated DEGs between human osteosarcoma cell line 143B and HOS cell exposed to Matrigel were screened out by microarray. GO categories such as "cell adhesion", "angiogenesis" were enriched in 143B group. PATHWAY analysis showed enriched TGF-beta, Wnt and VEGF signaling pathway in 143B group. The hub gene ITGA2 in signal-network of DEGs exhibited pro-VM and pro-metastasis effect. Our study provides fundamental data for further studies regarding molecules involved in osteosarcoma VM.

Abstract
AIM Strict criteria of typical left bundle branch block (LBBB) can help with the prediction for cardiac resynchronization therapy response. The aim of this study is to determine whether the use of strict criteria for both LBBB and right bundle branch block (RBBB) predicts successful QRS correction (≤130 ms) by left bundle branch area pacing (LBBAP). METHODS Consecutive patients with pacemaker indications according to the present guideline who also underwent LBBAP implantation were retrospectively assessed. Inclusion criteria were patients with BBB and the baseline QRSd > 130 ms. Baseline characteristics and pacing parameters were compared between typical and atypical BBB groups. Multivariate logistic regression was used to adjust for covariates that were found in univariate analyses for successful QRS correction by LBBAP. RESULTS Seventy-three patients were enrolled. Among them, 10 (13.6%) had atypical BBB (5 LBBB and 5 RBBB) and 63 (86.4%) had typical BBB (30 LBBB and 33 RBBB). The rate of successful QRS correction was higher in typical-BBB patients (52/63; 82.5%) than that in atypical-BBB patients (3/10; 30%), P < .001. Paced QRSd was obviously narrower in patients with typical BBB than that in patients with atypical-BBB (118 ± 14 vs 133 ± 14 ms, P = .003). In multivariate logistic regression, only typical BBB morphology and the implantation depth of 3830 pacing electrode in the ventricular septum were independent predictors for successful QRS correction. CONCLUSION This study demonstrates that patients with typical-BBB morphology benefit more from LBBAP for QRS correction. Typical BBB morphology together with deep penetration of 3830 ventricular electrode in the interventricular septum predicts the success of QRS correction by LBBAP.

Abstract
The application and theoretical analysis of fault tolerant learning are very important for neural networks. Our objective here is to realize fault tolerant sparse multilayer perceptron (MLP) networks. The stochastic gradient descent method has been employed to perform online learning for MLPs. For weight noise injection-based network models, it is a common strategy to add a weight decay regularizer while constructing the objective function for learning. However, this l2 -norm penalty does not generate sparse optimal solutions. In this paper, a group lasso penalty term is used as a regularizer, where a group is defined by the set of weights connected to a node from nodes in the preceding layer. Group lasso penalty enables us to prune redundant hidden nodes. Due to its nondifferentiability at the origin, a smooth approximation of the group lasso penalty is developed. Then, a rigorous proof for the asymptotic convergence of the learning algorithm is provided. Finally, some simulations have been performed to verify the sparseness of the network and the theoretical results.

Abstract
Objective: To compare the efficiency of saline irrigation, antibiotics irrigation and high-concentration antibiotics perfusion with tube drainage in the treatment of infectious effusion. Methods: Clinical and sonographic features of abdominal and pelvic infectious effusion of 64 patients with malignant tumor collected from September 2013 to September 2017 were retrospectively analyzed. The changes of effusion size and temperature, catheterization time were evaluated in saline irrigation group and antibiotics irrigation group. The catheterization time was compared between antibiotics irrigation group and high-concentration antibiotics perfusion group. Results: The effective rates of the saline irrigation group and the antibiotics irrigation group were 68.6% and 86.8%, respectively, and the times of catheterization were 11.9±8.4 days and 7.8±4.8 days, respectively, with significantly statistical difference (both P<0.05). However, the effective rates of the antibiotics irrigation group and the high concentration antibiotic perfusion group were 86.8% and 100.0%, respectively (P=0.067), while the times of catheterization were 7.8±4.8 days and 3.6±3.1 days, respectively (P<0.001). Conclusion: The antibiotic irrigation with tube drainage, especially the high concentration perfusion is more effective than saline in the treatment of abdominal and pelvic infection effusion.

Abstract
Objective Probiotics may be efficacious in preventing ventilator-associated pneumonia (VAP). The aim of this network meta-analysis (NMA) was to clarify the efficacy of different types of probiotics for preventing VAP. Methods This systematic review and NMA was conducted according to the updated preferred reporting items for systematic review and meta-analysis. A systematic literature search of public databases from inception to 17 June 2018 was performed. Results NMA showed that “Bifidobacterium longum + Lactobacillus bulgaricus + Streptococcus thermophiles” was more efficacious than “Ergyphilus” in preventing VAP (odds ratio: 0.15, 95% confidence interval: 0.03–0.94). According to pairwise meta-analysis, “B. longum + L. bulgaricus + S. thermophiles” and “Lactobacillus rhamnosus” were superior to placebo in preventing VAP. Treatment rank based on surface under the cumulative ranking curves revealed that the most efficacious treatment for preventing VAP was “B. longum + L. bulgaricus + S. thermophiles” (66%). In terms of reducing hospital mortality and ICU mortality, the most efficacious treatment was Synbiotic 2000FORTE (34% and 46%, respectively). Conclusions Based on efficacy ranking, “B. longum + L. bulgaricus + S. thermophiles” should be the first choice for prevention of VAP, while Synbiotic 2000FORTE has the potential to reduce in-hospital mortality and ICU mortality.

Abstract
BACKGROUND
Medulloblastoma (MB) is the most common malignant paediatric brain tumor. Recent studies show that M2 cells were relative more abundant in Shh subtype of MBs compared with other three subtypes. It’s known that M2 cells have close relationship with many tumors’ progression. But if they play any role in the progression of Shh subtype of MB is not yet clear. Many studies demonstrate that exosomes carring miRNAs have close relationship with tumor invasion. The aim of present study is to clarify the role of exosome miRNA between tumor cells and microglias during the progression of Shh subtype of medulloblastoma.
MATERIAL AND METHODS
Immunofluerescence staining using iNOS and Arg1, which is M1 and M2 specific marker, respectively, was performed in four subtypes of MBs. After coculture of exosomes extracted from Shh subtype of MB cell (DAOY) with microglia cell (BV2), Q-PCR and ELISA assay were done to evaluate the polarization status of the microglia. Transwell and scratch assay were then performed to detect the migration ability of DAOY cell after treatment of exosomes from polirized M2 cells. MiRNA sequencing by Ion Proton technology was then done to analyze the miRNAs expression level between Shh subtype and other subtype of MBs. Transformation assay was used to overexpress and inhibit the expression of these miRNAs respectively to further clarify the role of exosome miRNA in the polarization of BV2 cells.
RESULTS
M2 cells were observed more abundant than other three subtypes of tumors, supporting that M2 cells play some role in this subtype of MBs. Exosomes of DAOY cells can induce the polarization of M2 cells. The polarized M2 cells can improved the migration and invasion ability of DAOY cell. Dozens of miRNAs were identified with different expression level between Shh subtype of MBs and other subtype of MB cells. Among them, 4 miRNAs were reported to be related with polariztion of M2 in many other lesions. Three of the 4 miRNAs can induce the polarization of M2 in present study.
CONCLUSION
Our study demonstrated exosome miRNA play a critical role between tumor cells and microglias during the progression of Shh subtype of medulloblastoma.

Abstract
OBJECTIVE To investigate the infection factors associated with neurodysplasia in early and moderately preterm infants at a corrected age of 18 months. METHODS The preterm infants with a gestational age of 28 weeks to <34 weeks who were admitted to the neonatal intensive care unit and followed up at the outpatient service for high-risk preterm infants from June 2015 to December 2018 were enrolled as subjects. At a corrected age of 18 months, the revised Bayley Scales of Infant Development was used to evaluate neurodevelopment. Univariate and multivariate logistic regression analyses were used to investigate the infection factors affecting neurodevelopment. RESULTS A total of 138 early or moderately preterm infants were enrolled, among whom 59 had neurodysplasia at a corrected age of 18 months. The univariate logistic regression analysis showed that neurodysplasia was associated with late-onset infection, positive blood culture, and other systemic infections (P<0.05). The multivariate logistic regression analysis showed that late-onset infection was an independent risk factor for neurodysplasia (OR=1.510, 95%CI: 1.133-3.600, P<0.05). CONCLUSIONS Late-onset infection can increase the risk of neurodysplasia in early and moderately preterm infants.

Abstract
AIM To evaluate the efficacy and safety of intravitreal injection of conbercept in patients with neovascular age-related macular degeneration (AMD). METHODS Retrospective review of 66 eyes of 63 patients with neovascular AMD. All patients received 0.5 mg intravitreal injections of conbercept monthly for 3 consecutive months, and then pro re nata treatment was performed. The changes of best-corrected visual acuity (BCVA) and central macular thickness (CMT) were observed before and after treatments. Minimum follow-up time was 12mo. SPSS 22.0 statistical software was used for statistical analysis. RESULTS The mean BCVA and CMT of 66 eyes (63 patients) were 1.11±0.60, 533.20±219.95 µm at baseline, and were 0.68±0.38, 310.28±125.60 µm at 3mo. No subjects were lost during the first three months, the improvements were all significantly (P<0.05). During the whole follow-up time of 12mo, 15 subjects (18 eyes) were lost. The mean BCVA and CMT of the rest 48 eyes with the follow-up time at least 1y were 0.83±0.46 and 547.59±196.77 µm at baseline, after 3mo and 12mo of conbercept injections became 0.55±0.41, 318.24±141.29 µm and 0.55±0.51, 333.87±173.25 µm. The differences were significant (P<0.05). No serious complications were observed. CONCLUSION Intravitreal injection of conbercept appears to significantly improve visual acuity and anatomical outcomes in patients with neovascular AMD, no serious adverse reactions and complications are observed.

Abstract
Objective: To identify the candidate epigenetic biomarkers of Wnt subtype of medulloblastoma(MB). Methods: MicroRNAs(miRNAs) expression array was used to detect the expression of miRNAs in MB cell lines with or without treatment by demethylation reagent. Nanostring gene expression array was used to detect the expression level of mRNA in 45 samples of primary MB. Molecular subtyping was performed based on the NanoString data. The status of methylation was confirmed by methylation specific PCR. The expression of candidate miRNA was confirmed by real-time PCR. Results: All 45 MBs except one were classified into the four molecular groups: 4 in WNT group, 8 in SHH group, 16 were in Group3 and 16 in Group4. Methylation specific PCR (MSP) assay confirmed miR-449a was silenced due to aberrant DNA methylation in MB cell lines.WNT subtype of MBs showed relatively higher expression of miR-449a comparing with other subgroups. Conclusion: MiR-449a, a candidate tumor suppressor gene regulated by hypermethylation, is a novel potential epigenetic marker for WNT subtype of MBs.

Abstract
Purpose The aim of the present study was to construct a novel long non-coding RNA (lncRNA) signature to predict the prognosis of patients with cervical cancer (CC). Materials and methods We downloaded lncRNA expression profiles and clinical characteristics from The Cancer Genome Atlas database and randomly divided them into a training dataset (n=200) and a testing dataset (n=87). Using a Cox-based iterative sure independence screening procedure combined with a resampling technique, a lncRNA signature was calculated from prognostic lncRNAs in the training dataset and was independently verified in the testing and the entire datasets. In addition, multivariate Cox regression and further stratified analyses were performed, taking into consideration the lncRNA signature as well as other clinical characteristics. Finally, we predicted the underlying functional effects of the prognostic lncRNAs by using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses. Results We constructed a promising ten-lncRNA signature that was significantly associated with the prognosis of CC on the basis of a risk score formula. The risk score was used to classify patients into high-risk and low-risk groups with different overall survival in the training dataset, and was confirmed in the testing and entire datasets. Compared with the clinical factors, the ten-lncRNA signature was found to be an independent prognostic indicator and displayed robust prognostic performance. A functional analysis indicated that these ten lncRNAs were enriched in immune response, cell adhesion molecules and nuclear factor kappa B signaling. Conclusion Our results demonstrated that this ten-lncRNA signature may serve as a prognostic biomarker for patients with CC.

Abstract
Objective: To analyze the feature of breast complex cystic masses and to classify it at ultrasonography (US), which applied to the Breast Imaging Reporting and Data System (BI-RADS) categories 4a to 4c with pathological results as the golden standards. Methods: The ultrasonographic data and clinical features of 78 patients with complex cystic masses confirmed by pathology in Cancer Hospital from July 2014 to June 2017 were retrospectively reviewed. The complex cystic breast masses were divided into four classes on the basis of their US features: type 1 [thick wall and (or) thick septa (> 0.5 mm)], type 2 (one or more intra-cystic masses), type 3 (mixed cystic and solid components with cystic components more than 50%) and type 4 (mixed cystic and solid components with solid components more than 50%). Positive values (PPVs) were calculated for each type. Multiple linear regression analysis was used to analyze the ultrasonographic features of the masses (lesion size, margins, blood flow resistance index, calcification, and axillary lymph nodes, etc.) with malignant correlation. Results: There were 81 lesions in 78 patients. Among the 81 masses based on US appearance, 14 (17.3%) were classified as type Ⅰ, 18 (22.2%) as type Ⅱ, 18 (22.2%) as type Ⅲ, and 31 (38.3%) as type Ⅳ. The positive predictive values of the malignant lesions of type Ⅰ, type Ⅱ, Ⅲ and Ⅳ were 7.1%, 16.7%, 61.1% and 48.3%, respectively (P=0.040). In all the 81 masses, 14 were BI-RADS categories 4a, 18 were BI-RADS categories 4b and 49 were BI-RADS categories 4c. Masses with maximum diameter equal to or larger than 2.0 cm, unclear margins, RI≥0.7 and presence of abnormal axillary nodes assessment had a high probability of malignancy (P=0.030, 0.038, <0.001 and 0.025, respectively). Conclusion: Ultrasound typing is helpful for differentiating benign and malignant breast complex cysts and classifying BI-AIDS 4a to 4c, thus providing clearer treatment for clinical practice.

Abstract
Objective: To evaluate and compare the caries prevention effectiveness of a resin-based sealant and a glass ionomer sealant on permanent first molars in 7- to 9-years-old school children. Methods: A randomized controlled, examiner-blinded, 5-year clinical trial was conducted in 19 primary schools in Dalian, Liaoning province. Totally 419 children (with 664 first molars) who had at least one sound permanent first molar with deep fissures or fissures with signs of non-cavitated lesions were recruited and stratified and allocated randomly into three parallel groups. A resin-based sealant was used in Group R (136 children with 219 first molars) and a glass ionomer sealant was used in Group G (130 children with 218 first molars). The third group (Group N, 153 children with 227 first molars) with none of the two sealants applied was served as blank control. Follow-up examinations were conducted at 0.5, 1, 2, and 5 years after sealing in order to assess the retention of the sealants and the incidence of caries occurrence. Chi-square test was adopted to compare the differences of caries incidence among the 3 groups. Generalized estimating equations (GEE) was used to analyze the effective factors of caries incidence. Results: During the 5-year follow-up period, 13.4% (23/172) of the teeth in Group R, 22.5% (40/178) of the teeth in Group G and 34.5% (57/165) of the teeth in Group N were diagnosed as having developed cavitated lesions. And the differences in the incidence of caries among the three groups was statistically significant (P<0.05). According to GEE, the resin-based sealant and the glass ionomer sealant were found to be the protection factors and the non-cavitated lesion before sealing was found to be the risk factor. The resin-based sealant was found to be the protection factor to the glass ionomer sealant when the blank control group was removed. Conclusions: Both resin-based sealant and glass ionomer sealant could effectively prevent the permanent first molars from the occurrence of carious lesions in 5 years. The resin-based sealant was superior to the glass ionomer sealant in caries prevention.
