Abstract
BACKGROUND Cranioplasty is a common surgery in the neurosurgery for patients with skull defects following decompression craniectomy. Concomitant rare complications are increasingly reported, such as malignant cerebral edema after cranioplasty. CASE REPORT A 45-year-old man underwent decompression craniectomy due to traumatic brain injury. At 3 months after the decompression craniectomy, the patient developed refractory subdural hydrogen and received ipsilateral refractory subdural effusion capsule resection, but no significant relief was seen. Therefore, the cranioplasty was decided to treat subdural hydrogen and restore the normal appearance of the skull. After the successful cranioplasty surgery and the expected anesthesia recovery period, the pupils of the patients were continued to be dilated and fixed, without light reflection and spontaneous breathing. The Computed Tomography of the patient 1 hour after surgery showed malignant cerebral edema. CONCLUSIONS Malignant cerebral edema is a rare and lethal complication after cranioplasty. Negative pressure drainage and deregulation of cerebral blood flow at the end of cranioplasty may partially explain the malignant cerebral after cranioplasty. In addition, patients with epileptic seizures, no spontaneous breathing, dilated pupils without reflection, and hypotension within a short period after cranioplasty may show the occurrence of malignant cerebral.

Abstract
e14597 Background: Immune checkpoint inhibitors (ICI) PD-1/PD-L1 antibody are key drugs for the treatment of non-small cell lung cancer (NSCLC). Bispecific antibody is one of the strategies aimed at the clinical needs for NSCLC patients who are resistant to or refractory from ICI treatment. Tim-3, one of the next generation of ICB targets, is co-expressed on exhausted T cells with PD-1. It is also expressed by innate immune populations, including NK and DC. Dual blocking PD-1 and Tim-3 not only on T cells but also on DC, NK cells may achieve better clinical benefit. Methods: A bivalent to both Tim-3 and PD-1 bispecific antibody (Bis5) was developed and is in Phase I clinical trials for NSCLC patients who are resistant to or refractory from PD-1 antibody treatment. Results: Bis5 showed affinity of 5-8 nM to both Tim-3 and PD-1. Moreover, Bis5 showed better cell activity than Tim-3 and PD-1 antibody combination to activated T cell as well as NK and DC. Bis5 showed 77%-88% tumor inhibition which is close to PD-1 antibody alone in MC38 model. Neither PD-1 antibody or PD-1 and Tim-3 antibody combination show any activity in CT26 model while Bis5 showed significant tumor inhibition activity and doubled the survival rate. The highest non-severe toxicity dose (HNSTD) was 200mpk in monkeys. ADA were 33.3% (2/6), 83.3% (5/6), and 0.0% (0/6) at doses of 2, 10, and 50 mpk, respectively. The T1/2 were 31.7-66.5 h for doses 2-50 mpk. Conclusions: A Phase I, multicenter, open-label study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity and preliminary efficacy of Bis5 in patients with advanced and/or metastatic solid tumors has started. Seven cohorts (0.1, 0.3, 1, 3, 6, 10, 15 mg/kg) are planned to be enrolled sequentially in the dose escalation part. In the expansion part, a cohort group of 10 patients is planned for post PD-1 treated NSCLC as the second or third line treatment.

Abstract
e16240 Background: PD-1/PD-L1-targeted immunotherapies have become critical roles in the treatment for many tumors. However, there is limited progress in gastrointestinal cancers, especially in pancreatic ductal adenocarcinoma (PDAC). PDAC is low immunogenicity. PDAC microenvironment is immunosuppressive. More than 70% PDACs have few or no CD8+ T cells around the tumor cell or in the tumor microenvironment. Therefore, immunotherapy like PD-1/PD-L1 antibody alone is rarely effective for PDACs. Methods: Some cytokine or analogs may activate CD8+ T cells. An analog specifically activating tumor antigen associated (TAA) CD8+ T cells was fused to anti-CLDN18.2 antibody. Results: The specific bi-functional molecule (Bis2) has high affinity to human anti-CLDN18.2 (14pM) and CD8+T cells. Bis2 shows significant in vivo efficacy at 0.1 mpk. The efficacy lasts for more than 24 days, only given two doses at day 1 and day 3, respectively. IHC shows that the tumor infiltrated CD8+T cells significantly increased and IFNγ secretion enhanced as well. The IHC results are consistent with the mechanism that Bis2 induces TAA CD8+ T cell proliferation and prevents CD8+T cells from IFNγ-mediated apoptosis. Moreover, Bis2 also shows 100% tumor inhibition in combination with either chem (L-OHP+5FU) or PD-1 antibody in vivo which is better than chem in combination with PD-1 antibody. Bis2 also shows 60% tumor inhibition at 1mpk in CLDN18.2 negative cell based in vivo model. Bis2 shows ADA in monkeys in two weeks by dosing weekly. The repeated doses toxicity study shows an increase of MONO and %MONO and decrease in RBC, HGB, HCT, and MCHC. The HNSTD was 3mpk. The T1/2 was 40h. Conclusions: The Phase I study in advanced solid tumors is ongoing. The study uses accelerated titration starting from 0.01mpk combined with a BOIN design, maximum patient size of 36. In the expansion part, two cohorts of 10 CLDN18.2+ pancreatic cancer patients are planned for the treatment of Bis2 alone or Bis2 in combination with chemotherapy, respectively.

Abstract
Over the past decade, repeated studies demonstrated that the vertebrate brain had a specialized lymphatic transport pathway, which overturned the traditional concept of central nervous system (CNS) immune privilege. Despite the lack of lymphatic vessels, the glymphatic system and the meningeal lymphatic vessels provide a unique pathway for solutes transport and metabolites clearance in the brain. Sleep, circadian rhythm, arterial pulsation, and other physiological factors modulate this specialized lymphatic drainage pathway. It has also changed significantly under pathological conditions. These modulatory mechanisms may arise critical targets for the therapeutic of CNS disorders. This review highlights the latest research progress on the modulation of lymphatic transport in the CNS under physiological and pathological conditions. Furthermore, we examined the possible upstream and downstream relation networks between these regulatory mechanisms.

Abstract
The Z chromosome of the silkworm contains a major gene that influences silk yield. This major locus on chromosome Z accounts for 35.10% of the phenotypic variance. The location and identification of the gene have been a focus of silkworm genetics research. Unfortunately, identification of this gene has been difficult. We used extreme phenotype subpopulations and selected from a backcross population, BC1 M, which was obtained using the high-yield strain 872B and the low-yield strain IS-Dazao as parents, for mapping the gene on the chromosome Z. The candidate region was narrowed down to 134 kb at the tip of the chromosome. BmAbl1 in this region correlated with silk gland development by spatiotemporal expression analysis. This gene was differentially expressed in the posterior silk glands of the high- and low-yield strains. In BmAbl1, an insertion-deletion (indel) within the 10th exonic region and an SNP within the 6th intronic region were detected and shown to be associated with cocoon shell weight in 84 Bombyx mori strains with different yields. Nucleotide diversity analysis of BmAbl1 and its 50 kb flanking regions indicated that BmAbl1 has experienced strong artificial selection during silkworm domestication. This study is the first to identify the genes controlling silk yield in the major QTL of the Z chromosome using forward genetics.

Abstract
AIMS Metagenomic next-generation sequencing (mNGS) has been utilized for diagnosing infectious diseases. It is a culture-free and hypothesis-free nucleic acid test for diagnosing all pathogens with known genomic sequences, including bacteria, fungi, viruses and parasites. While this technique greatly expands the clinical capacity of pathogen detection, it is a second-line choice due to lengthy procedures and microbial contaminations introduced from wet-lab processes. As a result, we aimed to reduce the hands-on time and exogenous contaminations in mNGS. METHODS AND RESULTS We developed a device (NGSmaster) that automates the wet-lab workflow, including nucleic acid extraction, PCR-free library preparation and purification. It shortens the sample-to-results time to 16 and 18·5 h for DNA and RNA sequencing respectively. We used it to test cultured bacteria for validation of the workflow and bioinformatic pipeline. We also compared PCR-free with PCR-based library prep and discovered no differences in microbial reads. Moreover we analysed results by automation and manual testing and found that automation can significantly reduce microbial contaminations. Finally, we tested artificial and clinical samples and showed mNGS results were concordant with traditional culture. CONCLUSION NGSmaster can fulfil the microbiological diagnostic needs in a variety of sample types. SIGNIFICANCE AND IMPACT OF THE STUDY This study opens up an opportunity of performing in-house mNGS to reduce turnaround time and workload, instead of transferring potentially contagious specimen to a third-party laboratory.

Abstract
Objective: To explore the correlation between prostate imaging report and data system (PI-RADS) score and international society of uological pathology (ISUP) grade of prostate cancer (PCa) and the role of PI-RADS score in predicting the pathological features of clinically significant PCa (csPCa), positive surgical margin and pathological upgrade. Methods: The pathologically positive patients with multi-parameter magnetic resonance image (mpMRI) were included in this study. The patients with prostate specific antigen (PSA)<100 μg/L were divided into two groups: biopsy group (n=523) and RP group (n=215). The correlation between PI-RADS score and ISUP grade and the accuracy of predicting csPCa in the two groups were evaluated. In the RP group, the correlation between PI-RADS score and postoperative pathological grade or degradation and positive incisal margin was further discussed. The patients with PSA≥100 μg/L (171cases in biopsy group and 6 cases in RP group) were not included in the statistical analysis, and the results were simply described. Results: The age, prostate volume, and PSA level of biopsy group and RP group was (72±8) years vs (68±7) years, 48.3 (32-57) cm(3) vs 47.2 (32-54) cm(3), and 26.3(10.2-34.2)μg/L vs 21.7 (9.24-23.95)μg/L, respectively. The PI-RADS scores ≤ 3,4, and 5 in the biopsy group were 109,97, and 317 respectively, and those in the RP group were 61,55, and 99 respectively. There were significant differences in the composition of ISUP grades of different PI-RADS scores between the two groups (P<0.001), and there was a positive correlation between the two groups (r=0.493 in the biopsy group, r=0.671 in the RP group, both P<0.001). Using PI-RADS score to predict csPCa, biopsy group (AUC=0.764, P<0.001, 95%CI:0.710-0.819) and RP group (AUC=0.807, P<0.001, 95%CI:0.735-0.879) had certain accuracy. The PI-RADS score combined with PSA could improve the accuracy of csPCa prediction in the biopsy group (AUC=0.795,P<0.001, 95% CI:0.746-0.843) and the RP group (AUC=0.852, P<0.001, 95%CI:0.789-0.915). Compared with the pathological results of biopsy in the RP group, 52.6% of the patients showed upgrade and degrade of ISUP, and there was insignificant difference in the composition of PI-RADS scores between upgraded and degraded patients (P>0.05). However, 41.7%(27/65) of the patients with ISUP grade 1 biopsies had pathological upgrades that the patients with PI-RADS ≤ 3 accounted for 33.3%, while the patients with PI-RADS>3 accounted for 66.7%, and there was significant difference between the two groups (P<0.05). After RP, 43.3% of the patients had positive surgical margins, and the patients with PI-RADS score ≤ 3, 4 and 5 were 13 (14%), 24 (25.8%) and 56 (60.2%), respectively, while the PI-RADS scores of patients with negative surgical margin were 48 (39.3%), 31(25.4%) and 43(35.2%), respectively. There was significant difference between the two groups (P<0.001). The higher the PI-RADS score, the greater the possibility of the positive surgical margin. For the patients with PSA ≥ 100 μg/L, 98.8% (169/171) patients in the biopsy group had a PI-RADS score 5. The pathological results of all patients were csPCa, of which 85.4% (146/171) had ISUP grade ≥ 4. Among them, 6 cases underwent RP, 5 cases had ISUP grade ≥ 4, all surgical margin were positive, 5 cases had seminal vesicle invasion, 3 cases had capsule invasion and 3 cases had positive pelvic lymph nodes. Conclusion: ThePI-RADS score is correlated with the ISUP grade of PCa. Combined with PSA can accurately predict csPCa. At the same time, the higher PI-RADS score, the more likely the patients with positive incisal margin after RP and Gleason score of 3+3=6 at the time of puncture will be upgraded pathologically.

Abstract
The emergence and spread of multidrug-resistant Staphylococcus aureus (S. aureus) necessitate the research on therapeutic tactics which are different from classical antibiotics in overcoming resistance andtreatinginfections. In S. aureus, von Willebrand factor-binding protein (vWbp) is one of the key virulence determinants because it mediates not only the activation of thrombin to convert fibrinogen to fibrin, thereby enabling S. aureus to escape from the host immune clearance, but also the adhesion of S. aureus to host cells. Thus, vWbp is regarded as a promising druggable target to treat S. aureus-associated infections. Here we identify that baicalein, a natural compound isolated from the Chinese herb Scutellaria baicalensis, can effectively block the coagulase activity of vWbp without inhibiting the growth of the bacteria. Through thermal shift and fluorescence quenching assays, we demonstrated that baicalein directly binds to vWbp. Molecular dynamics simulations and mutagenesis assays revealed that the Asp-75 and Lys-80 residues are necessary for baicalein binding to vWbp. Importantly, we demonstrated that baicalein treatment attenuates the virulence of S. aureus and protects mice from S. aureus-induced lethal pneumonia. In addition, baicalein can improve the therapeutic effect of penicillin G by 75% in vivo. These findings indicate that baicalein might be developed as a promising therapeutic agent against drug-resistant S. aureus infections.

Abstract
Post-traumatic basal ganglia-internal capsule (BGIC) infarction in pediatric patients is a relatively rare consequence of mild head injury (MHI). To the best of the authors' knowledge, at present, no comprehensive review has been published. To review research on BGIC infarction after MHI, a literature search was performed using the PubMed database and relevant search terms. According to recent data, MHI may cause BGIC infarction due to mechanical vasospasm of the perforating vessels in pediatric patients. The anatomical characteristics of the growing brain in infancy, mineralization of the lenticulostriate arteries and viral infection may all play a part in BGIC infarction after MHI, which often occurs within 24 months. Symptoms are not as severe and tend to disappear in the early period. Computed tomography or magnetic resonance imaging often shows BGIC infarction. There are also children with scattered calcification of the basal ganglia. Neural rehabilitation is a commonly accepted treatment. The prognosis of patients with BGIC infarction after MHI consistently improves.

Abstract
Staphylococcus aureus (S. aureus), especially methicillin-resistant Staphylococcus aureus (MRSA), is a major cause of pneumonia, resulting in severe morbidity and mortality in adults and children. Sortase A (SrtA), which mediates the anchoring of cell surface proteins in the cell wall, is an important virulence factor of S. aureus. Here, we found that salvianolic acid A (Sal A), which is a natural product that does not affect the growth of S. aureus, could inhibit SrtA activity (IC50 = 5.75 μg/ml) and repress the adhesion of bacteria to fibrinogen, the anchoring of protein A to cell wall, the biofilm formation, and the ability of S. aureus to invade A549 cells. Furthermore, in vivo studies demonstrated that Sal A treatment reduced inflammation and protected mice against lethal pneumonia caused by MRSA. More significantly, full protection (a survival rate of 100%) was achieved when Sal A was administered in combination with latamoxef. Together, these results indicate that Sal A could be developed into a promising therapeutic drug to combat MRSA infections while limiting resistance development.

Abstract
Accumulation of amyloid β (Aβ) peptide, inflammation, and oxidative stress contribute to Alzheimer's disease (AD) and trigger complex pathogenesis. The ketone body β-hydroxybutyrate (BHBA) is an endogenous metabolic intermediate that protects against stroke and neurodegenerative diseases, but the underlying mechanisms are unclear. The present study aims to elucidate the protective effects of BHBA in the early stage of AD model and investigate the underlying molecular mechanisms. Three-and-half-month-old double-transgenic mice (5XFAD) overexpressing β-amyloid precursor protein (APP) and presenilin-1 (PS1) were used as the AD model. The 5XFAD mice received 1.5 mmol/kg/d BHBA subcutaneously for 28 days. Morris water maze test, nest construction, and passive avoidance experiments were performed to assess the therapeutic effects on AD prevention in vivo, and brain pathology of 5XFAD mice including amyloid plaque deposition and microglia activation were assessed. Gene expression profiles in the cortexes of 5XFAD- and BHBA-treated 5XFAD mice were performed with high-throughput sequencing and bioinformatic analysis. Mouse HT22 cells were treated with 2 mM BHBA to explore its in vitro protective effects of BHBA on hippocampal neurons against Aβ oligomer toxicity, ATP production, ROS generation, and mitochondrial aerobic respiratory function. APP, BACE1, and neprilysin (NEP) expression levels were evaluated in HT22 cells following treatment with BHBA by measuring the presence or absence of G protein-coupled receptor 109A (GPR109A). BHBA improved cognitive function of 5XFAD mice in Morris water maze test, nesting construction and passive avoidance experiments, and attenuated Aβ accumulation and microglia overactivation in the brain. BHBA also enhanced mitochondrial respiratory function of hippocampal neurons and protected it from Aβ toxicity. The enzymes, APP and NEP were regulated by BHBA via G-protein-coupled receptor 109A (GPR109A). Furthermore, RNA sequencing revealed that BHBA-regulated genes mainly annotated in aging, immune system, nervous system, and neurodegenerative diseases. Our data suggested that BHBA confers protection against the AD-like pathological events in the AD mouse model by targeting multiple aspects of AD and it may become a promising candidate for the prevention and treatment of AD.

Abstract
van der Waals (vdW) heterostructures, which are produced by the precise assemblies of varieties of two-dimensional (2D) materials, have demonstrated many novel properties and functionalities. Here we report a nanoplasmonic study of vdW heterostructures that were produced by depositing ordered molecular layers of pentacene on top of graphene. We find through nanoinfrared (IR) imaging that surface plasmons formed due to the collective oscillations of Dirac Fermions in graphene are highly sensitive to the adjacent pentacene layers. In particular, the plasmon wavelength declines systematically but nonlinearly with increasing pentacene thickness. Further analysis and density functional theory (DFT) calculations indicate that the observed peculiar thickness dependence is mainly due to the tunneling-type electron transfer from pentacene to graphene. Our work unveils a new method for tailoring graphene plasmons and deepens our understanding of the intriguing nano-optical phenomena due to interlayer couplings in novel vdW heterostructures.

Abstract
Objective: To evaluate the effect of multimodal analgesia using periprostatic nerve block anesthesia (PNB) combined with flurbiprofen in patients undergoing transperineal template-guided prostate biopsy (TTPB). Methods: Totally 166 patients (aged (68.2±9.1) years, range: 47 to 81 years) who received TTPB from October 2017 to June 2018 at Department of Urology, Northern Jiangsu People's Hospital Affiliated to Yangzhou University were enrolled prospectively. All the patients were randomly divided into 2 groups. The observation group (n=79) was given flurbiprofen axetil 1 mg/kg intravenously for half an hour before operation and lidocaine was used for PNB before the biopsy. The control group (n=87) was given normal saline combined with PNB. A visual analog scale (VAS) and visual numeric scale (VNS) were used to assess the patients' pain and quantify their satisfaction at two time points: VAS-1 and VNS-1: during biopsy procedure, VAS-2 and VNS-2: 30 min after the procedure. The date were compared by t test, χ(2) test, Fisher exact test and two-way repeated measures anova analysis between the 2 groups. Results: The age, total prostate volume, serum prostate-specific antigen and the number of cores were comparable among the 2 groups (P>0.05). The VAS-1 scores of the control group and the observation group were 2.8±1.7, 1.9±1.2, respectively, and the VNS-1 were 3.1±0.7, 3.4±0.3, respectively. The VAS-1 were significantly lower in observation group than in control group (F=3.904, P=0.000). Conversely, the VNS-1 were higher in observation group (F=3.526, P=0.000). At 30-minute postoperative, the VAS-2 and VNS-2 were 0.7±0.4 and 3.7±0.2 in the control group, respectively. The VAS-2 and VNS-2 were 0.6±0.5 and 3.8±0.1 in the observation group, respectively. There were no significant differences in the pain scores or the satisfaction scores between the 2 groups (F=1.429, 2.825; P=0.136, 0.083). The incidence of overall complications was 26.4% (23/87) in the control group and 25.3% (20/79) in the observation group, with no statistical difference between the 2 groups (χ(2)=0.027, P=0.869). And the complications had no statistically significant difference among the 2 groups including hematuria, urinary retention, infection, hematospermia, vascular and neurological reactions, nausea, vomiting, dizziness, headache, and respiratory depression (P>0.05). Conclusion: The multimodal analgesia induced by PNB and flurbiprofen could effectively relieve the pain for patients who received TTPB.

Abstract
Sepsis induced by major burns, trauma, and hemorrhage, remains a major cause of death of patients in intensive care units, and it may result in both the widespread activation and dysfunction of the innate as well as adaptive responses in host immune system. A large amount of information concerning subsets of innate and adaptive immune cells in sepsis has implicated that these cells, including neutrophils, macrophages, dendritic cells, T lymphocytes, regulatory T lymphocytes, and natural killer cells, have profound effects on immunoreactivity during acute insults or sepsis through modulating multiple receptor expressions or cytokine secretion, in turn contributing to the development and outcome of sepsis. It is of great significance that precision monitoring of immune function and the related indicators might help to assess the risk of secondary infection, the prognosis of septic patients, and guide the treatment of septic complications.

Abstract
Previously, we have demonstrated that human tissue kallikrein 1 (hKLK1) improves age-related erectile dysfunction (ED). Autophagy has been implicated in age-related diseases, including ED. However, the molecular mechanisms underlying hKLK1-mediated amelioration of age-related ED via regulation of autophagy remains unknown. To explore the potential mechanism, male wild-type Sprague-Dawley rats (WTR) and transgenic rats harboring human KLK1 (TGR) were bred till 4 or 18 months of age and divided into three groups: young WTR (yWTR) as the control group, aged WTR (aWTR) group, and aged TGR (aTGR) group. The erectile function of each rat was evaluated using cavernous nerve electrostimulation. The ratio of intracavernous pressure/mean arterial pressure (ICP/MAP) and total ICP were also measured. Western blotting, immunohistochemistry, and transmission electron microscopy were performed to detect the levels of autophagy. The expression levels of related signaling pathways were determined by western blotting and immunohistochemistry. We found that hKLK1 improved the impaired erectile function of aged rats. Compared to the yWTR and aTGR groups, the aWTR group showed reduced smooth muscle/collagen ratio, fewer autophagosomes, and lower expression of Beclin 1 and LC3-II, which indicate impaired smooth muscle function and low level of autophagy in the smooth muscle cells. Moreover, the PI3K/Akt/mTOR signaling pathway, which is considered to be a negative regulator of autophagy, was upregulated in the aWTR group. hKLK1 may partially restore erectile function in aged transgenic rats by upregulating protective autophagy via the PI3K/Akt/mTOR pathway. These observations indicate that hKLK1 is a potential gene therapy candidate for age-related ED.

Abstract
We report a systematic plasmonic study of twisted bilayer graphene (TBLG)-two graphene layers stacked with a twist angle. Through real-space nanoimaging of TBLG single crystals with a wide distribution of twist angles, we find that TBLG supports confined infrared plasmons that are sensitively dependent on the twist angle. At small twist angles, TBLG has a plasmon wavelength comparable to that of single-layer graphene. At larger twist angles, the plasmon wavelength of TBLG increases significantly with apparently lower damping. Further analysis and modeling indicate that the observed twist-angle dependence of TBLG plasmons in the Dirac linear regime is mainly due to the Fermi-velocity renormalization, a direct consequence of interlayer electronic coupling. Our work unveils the tailored plasmonic characteristics of TBLG and deepens our understanding of the intriguing nano-optical physics in novel van der Waals coupled two-dimensional materials.

Abstract
Ventriculoperitoneal shunts (VPS) are the primary treatment for hydrocephalus and are associated with a high risk of complications, specifically in patients who are obese or have abdominal adhesions or shunt revisions. The present study describes the use of a novel type of peritoneal catheter peritoneocentesis trocar insertion with the assistance of a one-port laparoscope. A total of 36 patients with hydrocephalus underwent this novel type of peritoneocentesis trocar-assisted VPS. The distal shunt catheter was placed into the right subdiaphragmatic space and the catheter was traversed through a single hole drilled through the liver falciform ligament. The duration of the laparoscopic surgery ranged from 6–18 min (mean 10.4±1.6 min). No shunt-related infections or catheter malfunctions or injuries to the intra-abdominal organs occurred. The total abdominal incision length was 1.0 cm (0.5+0.5 cm). No laparoscopy-related complications were observed during follow-up assessments. The novel approach used in the current study is very easy to perform, and this method may significantly reduce the risk of malfunction complications. The presented method also has the advantages of reduced trauma and a simpler surgery. The current study indicated that this simple, minimally invasive procedure was beneficial for patients with hydrocephalus, specifically in cases of patients with obesity, peritoneal adhesions or shunt revisions.

Abstract
We report a nanoinfrared (IR) imaging study of the localized plasmon resonance modes of graphene nanoribbons (GNRs) using a scattering-type scanning near-field optical microscope (s-SNOM). By comparing the imaging data of GNRs that are aligned parallel and perpendicular to the in-plane component of the excitation laser field, we observed symmetric and asymmetric plasmonic interference fringes, respectively. Theoretical analysis indicates that the asymmetric fringes are formed due to the interplay between the localized surface plasmon resonance (SPR) mode excited by the GNRs and the propagative surface plasmon polariton (SPP) mode launched by the s-SNOM tip. With rigorous simulations, we reproduce the observed fringe patterns and address quantitatively the role of the s-SNOM tip on both the SPR and SPP modes. Furthermore, we have seen real-space signatures of both the dipole and higher-order SPR modes by varying the ribbon width.

Abstract
A growing body of evidence suggests that microRNA-592 is involved in tumor initiation and development in several types of human cancers. However, the biological functions and molecular mechanism of microRNA-592 in glioma remain unclear. In this study, we explored the potential role of microRNA-592 in glioma as well as the possible molecular mechanisms. Our results proved that microRNA-592 expression was significantly downregulated in glioma tissues and cell lines (p < 0.01). Functional assays revealed that overexpression of microRNA-592 dramatically reduced the cell proliferation, migration, and invasion and induced cell arrest at G1/G0 phase in vitro. Mechanistic investigations defined insulin-like growth factor binding protein 2 as a direct and functional downstream target of microRNA-592, which was involved in the microRNA-592-mediated tumor-suppressive effects in glioma cells. Moreover, the in vivo study showed that microRNA-592 overexpression produced the smaller tumor volume and weight in nude mice. In summary, these results elucidated the function of microRNA-592 in glioma progression and suggested a promising application of it in glioma treatment.

Abstract
AIM To obtain co-cultures of anaerobic fungi and their indigenously associated methanogens from the rumen of yaks grazing on the Qinghai-Tibetan Plateau and investigate their morphology features and ability to degrade lignocellulose. METHODS AND RESULTS Twenty fungus-methanogen co-cultures were obtained by Hungate roll-tube technique. The fungi were identified as Orpinomyces, Neocallimastix and Piromyces genera based on the morphological characteristics and internal transcribed spacer 1 sequences analysis. All methanogens were identified as Methanobrevibacter sp. by 16S rRNA gene sequencing. There were four types of co-cultures: Neocallimastix with Methanobrevibacter ruminantium, Orpinomyces with M. ruminantium, Orpinomyces with Methanobrevibacter millerae and Piromyces with M. ruminantium among 20 co-cultures. In vitro studies with wheat straw as substrate showed that the Neocallimastix with M. ruminantium co-cultures and Piromyces with M. ruminantium co-cultures exhibited higher xylanase, filter paper cellulase (FPase), ferulic acid esterase, acetyl esterase activities, in vitro dry matter digestibility, gas, CH4 , acetate production, ferulic acid and p-coumaric acid releases. The Neocallimastix frontalis Yak16 with M. ruminantium co-culture presented the strongest lignocellulose degradation ability among 20 co-cultures. CONCLUSIONS Twenty fungus-methanogen co-cultures were obtained from the rumen of grazing yaks. The N. frontalis with M. ruminantium co-cultures were highly effective combination for developing a fermentative system that bioconverts lignocellulose to high activity fibre-degrading enzyme, CH4 and acetate. SIGNIFICANCE AND IMPACT OF THE STUDY The N. frontalis with M. ruminantium co-cultures from yaks grazing on the Qinghai-Tibetan Plateau present great potential in lignocellulose biodegradation industry.

Abstract
OBJECTIVES We attempted to discover the regulatory role of miR-17 and PTEN in glial scar formation accompanied with spinal cord injuries. METHODS We established a spinal cord injury (SCI) model in mice which were transfected with different groups of adenoviruses: miR-17 mimics, miR-17 inhibitors and PTEN cDNAs. The improvement of hind limb functions was assessed using the 21-point Basso-Beattie-Bresnahan (BBB) locomotion scale. Immunohistochemistry was used to detect the expression levels of glial fibrillary acidic protein (GFAP), Vimentin and neurofilaments. The expression of miR-17 was quantified using Real time-PCR (RT-PCR). Western blot was conducted to detect the expressions of PTEN, PI3K, Akt, mTOR and S6. Finally, dual luciferase reporter gene assay was conducted to confirm the target relationship between miR-17 and PTEN. RESULTS The model group exhibited significantly increased expression levels of GFAP, Vimentin, miR-17, PTEN, PI3K, Akt and mTOR. The above trend was enhanced by the transfection of miR-17 mimics (P<0.05). By contrast, the transfection of miR-17 inhibitors significantly down-regulated the expression of GFAP, Vimentin, PTEN, PI3K, Akt, mTOR and p-S6 whereas the expression of GFAP, Vimentin, PI3K, Akt, mTOR and p-S6 in the cells transfected with PTEN cDNAs significantly decreased (P<0.05). Also, the transfection of miR-17 inhibitors and PTEN cDNAs alleviated the astrogliosis in SCI lesions, contributed to the regeneration of nerve filament and improved the functional recovery of the hind limb of mice. Finally, the targeting relationship between miR-17 and PTEN was verified by the dual luciferase reporter gene assay. CONCLUSION MiR-17 is able to target PTEN and stimulate the PI3K/Akt/mTOR pathway. The formation of glial scar resulted from spinal cord injuries can be reduced either by inhibiting miR-17 or by overexpressing PTEN.

Abstract
MicroRNA-141 (miR-141) has been reported to function as tumor suppressor in many types of cancer. However, the molecular function and underlying mechanisms of miR-141 in glioma is still unknown. The aims of this study were to investigate miR-141 expression and determine its biological function and underlying mechanism in glioma. In this study, we found that miR-141 expression levels, both in glioma cell lines and in tissues, were significantly lower than that in a normal human astrocyte cell line or adjacent non-cancerous tissues. Overexpression of miR-141 significantly inhibited glioma cell proliferation, colony formation, migration and invasion in vitro, as well as suppressed glioma tumor growth in vivo. In addition, transforming growth factor beta 2 (TGF-β2) was identified as a target of miR-141 in glioma cells. TGF-β2 expression was also found to be upregulated, and negatively associated with miR-141 in glioma tissues. TGF-β2 over-expression partly reversed the effect caused by transfection of miR-141 mimic. These findings together suggested that miR-141 functioned as tumor suppressor by targeting TGF-β2, and that miR-141 might be a promising therapeutic strategy for future treatment of glioma.

Abstract
OBJECTIVE To investigate the management of early bronchopleural fistula(BPF) within one month after pneumonectomy. METHODS A total of 30 cases developed BPF within one month after pneumonectomy in recent 30 years were reviewed from First Hospital of Jilin University. All patients were treated by reoperation, closed drainage with or without open thoracic window, or endobronchial glue. RESULTS Seventeen patients were returned to the operating room for reclosure of BPF, one patients died of BPF and 16 reoperations were successful.Twelve cases were treated by closed drainage with or without followed open thoracic window. In 6 patients who were managed by closed drainage alone, 2 cases died of BPF and 4 bronchopleural fistulas closed spontaneously. In 6 patients treated with closed drainage and later with open thoracic window, one case died of BPF. One patient successfully underwent endoscopic glue to close BPF with injection three times. CONCLUSION Within one month postoperatively, BPF without established empyema with pus should be reoperated if the patient had enough cardiopulmonary reserve and could there fore tolerate reoperation. Contamination of pleural space is not the contraindication to reoperation. Reclosure via original thoracotomy and repair the fistula with pedicled intercostal muscle flap are convenient and efficient. Drainage with or without followed open thoracic window is appropriate for the patients with limited cardiopulmonary reserve, impaired general condition, secondary to empyema with pus, early recurred cancer, or some small fistulas.

Abstract
Data on the molecular epidemiology of Bordetella pertussis are limited in developing countries where whole-cell pertussis vaccines (WCVs) have been used. The aim of this study was to determine the genotypes of circulating B. pertussis in China by direct molecular typing of clinical specimens. DNA extracts of 122 nasopharyngeal swabs (NPs) positive for B. pertussis by polymerase chain reaction (PCR) (targeting IS481 and ptx-Pr) from 2012 to 2013 were used for typing using the multiple-locus variable number tandem repeat analysis (MLVA) and also by PCR-based multilocus sequence typing (MLST) of B. pertussis virulence genes (ptxP, prn, and fim3). One hundred and eight DNA extracts (89 %) generated a complete MLVA type (MT). Among the 18 MTs obtained, MT55 (52 %) and MT104 (13 %) were the most common. MT27, which is linked to the ptxP3 allele and is prevalent in many developed countries using acellular pertussis vaccines (ACVs), was only found in 7 (6 %) DNA extracts. Eighty-seven DNA extracts (71 %) produced a complete multiantigen sequence typing (MAST) type. Of them, 77 (89 %) had the ptxP1/prn1/fim3-1 allele profile. Four DNA extracts (5 %) had the ptxP3/prn2/fim3-2 profile and 3 (4 %) had the ptxP3/prn1/fim3-2 allele profile. These seven DNA extracts also harbored MT27. Our result shows that B. pertussis circulating in China was different from those found in countries where ACVs have been in use, supporting the notion that selection pressure induced by WCVs and ACVs on the bacterial population differs.

Abstract
Background Glioblastoma multiforme is one of the most deadly forms of brain cancer. We investigated the regulatory effects of microRNA-100 (miR-100) on cell proliferation, migration, and chemosensitivity in human glioblastoma. Methods miR-100 expression was assessed by quantitative real-time polymerase chain reaction in both glioblastoma cells and human tumors. Lentiviruses of miR-100 mimics and inhibitors were transfected into U251 and T98G cells. The regulatory effects of either overexpressing or downregulating miR-100 on glioblastoma were evaluated by a viability assay, growth assay, migration assay, chemosensitivity assay, and an in vivo tumor transplantation assay. Expression of fibroblast growth factor receptor 3 (FGFR3), the bioinformatically predicted target of miR-100, was examined by Western blot in glioblastoma. FGFR3 was then ectopically overexpressed in U251 and T98G cells, and its effects on miR-100-mediated cancer regulation were evaluated by growth, migration, and chemosensitivity assays. Results MiR-100 was markedly downregulated in both glioblastoma cell lines and human tumors. Overexpressing miR-100 through lentiviral transfection in U251 and T98G cells significantly inhibited cancer growth (both in vitro and in vivo) and migration and increased chemosensitivity to cisplatin and 1, 3-bis (2-chloroethyl)-l-nitrosourea, whereas downregulation of miR-100 had no effects on development of cancer. FGFR3 was directly regulated by miR-100 in glioblastoma. Ectopically overexpressing FGFR3 was able to ameliorate the anticancer effects of upregulation of miR-100 on glioblastoma growth, migration, and chemosensitivity. Conclusion MiR-100 was generally downregulated in glioblastoma. Overexpressing miR-100 had anticancer effects on glioblastoma, likely through regulation of FGFR3. The MiR-100/FGFR3 signaling pathway might be a biochemical target for treatment in patients with glioblastoma.

Abstract
MicroRNA-506 (miR-506) has been reported to act as a tumor suppressive or an oncogenic miRNA in different types of tumors. However, the roles and underlying molecular mechanism of miR-506 in glioma remain unclear. In the present study, we performed quantitative PCR to investigate the level of miR-506 in 36 pairs of glioma tumor and matched adjacent tissues, and found that miR-506 was downregulated in the glioma tumors compared to the expression in the adjacent normal tissues. Furthermore, a functional assay found that ectopic expression of miR-506 in glioma cells markedly suppressed cell proliferation, colony formation, migration and invasion, and suppressed tumor growth in vivo. Moreover, signal transducer and activator of transcription 3 (STAT3) was identified as a direct target of miR-506. Western blot assay showed that overexpression of miR-506 not only induced changes in STAT3 expression but also altered expression of its downstream genes, including, Bcl2, cyclin D1 and matrix metalloproteinase 2 (MMP-2), in the human glioma cells. In addition, STAT3 mRNA expression was increased in the glioma tissues, and was inversely correlated with miR-506. Importantly, overexpression of STAT3 in glioma cells attenuated the suppressive effects of miR-506 on cell proliferation, colony formation, migration and invasion. These results showed that miR-506 functions as a tumor suppressor in glioma by targeting STAT3, suggesting that miR-506 may serve as a potential target in the treatment of human glioma.

Abstract
MicroRNA (miR-126) was reported to be downregulated and to act as a tumor suppressor in cancers of the lung, cervix, bladder, breast, liver and prostate. However, the precise roles and underling mechanisms of miR-126 in glioma remain largely unknown. This study is aimed to study the role of miR-126 in the progression of glioma and to elucidate underlying miR-126-mediated mechanisms in glioma. Our results revealed that miR-126 was downregulated in the collected glioma specimen, compared with non-cancerous brain tissues. Restored miR-126 expression inhibited cell proliferation, colony formation, migration and invasion, and induced cell cycle arrest at G0/G1 phase and cell apoptosis of U-87 MG glioma cells. Overexpression of miR-126 was also able to suppress the growth of U-87 MG glioma xenografts in mice. Furthermore, insulin receptor substrate 1 (IRS-1) were identified as a target of miR-126, and showed that it was negatively regulated by miR-126 in glioma cells. We also demonstrated that overexpression of miR-126 suppressed PI3K and AKT activation, which contribute to suppress tumor growth of glioma. Taken together, these findings showed that miR-126 functions as a tumor suppressor in glioma cells by targeting IRS-1 expression via the PI3K/AKT signaling pathways, suggesting that miR-126 might be a novel target for therapeutic strategies in glioma.

Abstract
BACKGROUND Endothelial progenitor cells (EPCs) are important for endothelial regeneration and angiogenesis. Thrombin protease-activated receptor 1 (PAR1) PAR1 and PAR4 stimulation induces selective release of platelet proangiogenic and antiangiogenic regulators. OBJECTIVE To investigate if PAR1-stimulated platelet releasate (PAR1-PR) and PAR4-PR regulate angiogenic properties of EPCs in different manners. METHODS AND RESULTS EPCs were generated from peripheral mononuclear cell culture. Washed platelets (2 × 10(9) mL(-1)) were stimulated by PAR1-activating peptide (PAR1-AP; 10 μmol L(-1)) or PAR4-AP (100 μmol L(-1)) to prepare PAR1-PR and PAR4-PR, respectively. PAR1-PR or PAR4-PR had little influence on EPC proliferation. EPC migration experiments using a modified Boyden chamber showed that both platelet releasates facilitated EPC migration. As for in vitro tube formation on Matrigel, PAR1-PR and PAR4-PR similarly enhanced capillary-like network formation of EPCs in the complete EPC medium containing 10% FBS and a cocktail of growth factors, while PAR1-PR more profoundly increased EPC tube formation in basal culture medium supplemented with only 0.5% FBS than did PAR4-PR. The latter was confirmed in the murine angiogenesis model of subcutaneous Matrigel implantation. Moreover, blockade of vascular endothelial growth factor, stromal cell-derived factor 1α, or matrix metalloproteinases attenuated EPC migration and tube formation, suggesting a cooperation of these factors in the enhancements. CONCLUSIONS PAR1-PR enhances vasculogenesis more potently than PAR4-PR, and the enhancements require a cooperation of multiple platelet-derived angiogenic regulators.

Abstract
Congenital nephrotic syndrome (CNS) is defined as heavy proteinuria or nephrotic syndrome occurring before 3 months of age. It is characterized by early onset and progresses to end-stage renal disease. Recently, several genes associated with CNS have been identified, including NPHS1 and NPHS2. Mutations in the NPHS1 gene have been identified in patients with CNS in Finland with relatively high frequency. Thus far, only a few case reports about CNS have described an NPHS1 mutation in China. In this study, mutational analyses of NPHS1 and NPHS2 were performed in a Chinese child with CNS. Mutations were analyzed in all exons and exon/intron boundaries of NPHS1 and NPHS2 in the patient and his parents as well as in 50 unrelated controls using polymerase chain reaction and direct sequencing techniques. No mutations were detected in NPHS2. A novel splice site mutation (IVS11+1G>A) within intron 11 and a missense mutation within exon 8 (c.928G>A) in the NPHS1 gene were detected in the child. The child's mother had normal urinalysis and a c.928G>A (D310N) heterozygous mutation, and his father had normal urinalysis and IVS11+1G>A. These were not identified in the 50 unrelated controls. The novel splice site mutation of IVS11+1G>A and a missense mutation at c.928G>A in NPHS1 were found to cause CNS in this Chinese child.

Abstract
Background and Purpose Accumulating evidences have demonstrated that nuclear factor κB/p65 plays a protective role in the protection of ischemic preconditioning and detrimental role in lethal ischemia-induced programmed cell death including apoptosis and autophagic death. However, its role in the protection of ischemic postconditioning is still unclear. Methods Rat MCAO model was used to produce transient focal ischemia. The procedure of ischemic postconditioning consisted of three cycles of 30 seconds reperfusion/reocclusion of MCA. The volume of cerebral infarction was measured by TTC staining and neuronal apoptosis was detected by TUNEL staining. Western blotting was used to analyze the changes in protein levels of Caspase-3, NF-κB/p65, phosphor- NF-κB/p65, IκBα, phosphor- IκBα, Noxa, Bim and Bax between rats treated with and without ischemic postconditioning. Laser scanning confocal microscopy was used to examine the distribution of NF-κB/p65 and Noxa. Results Ischemic postconditioning made transient focal ischemia-induced infarct volume decrease obviously from 38.6%±5.8% to 23.5%±4.3%, and apoptosis rate reduce significantly from 46.5%±6.2 to 29.6%±5.3% at reperfusion 24 h following 2 h focal cerebral ischemia. Western blotting analysis showed that ischemic postconditioning suppressed markedly the reduction of NF-κB/p65 in cytoplasm, but elevated its content in nucleus either at reperfusion 6 h or 24 h. Moreover, the decrease of IκBα and the increase of phosphorylated IκBα and phosphorylated NF-κB/p65 at indicated reperfusion time were reversed by ischemic postconditioning. Correspondingly, proapoptotic proteins Caspase-3, cleaved Caspase-3, Noxa, Bim and Bax were all mitigated significantly by ischemic postconditioning. Confocal microscopy revealed that ischemic postconditioning not only attenuated ischemia-induced translocation of NF-κB/p65 from neuronal cytoplasm to nucleus, but also inhibited the abnormal expression of proapoptotic protein Noxa within neurons. Conclusions We demonstrated in this study that the protection of ischemic postconditioning on neuronal apoptosis caused by transient focal ischemia is associated with attenuation of the activation of NF-κB/p65 in neurons.

Abstract
Myeloid-derived suppressor cells (MDSC) are negative regulators of the immune response and are in part responsible for the inhibition of the T cell-mediated immune responses. While MDSC have been demonstrated to participate in the induction of prolonged allograft survival in animal models of transplantation, little is known about their immune regulatory function in human transplant recipients. Here, we report that two subsets of human MDSC expressing CD11b(+), CD33(+) and HLA-DR(-) develop in renal patients posttransplantation. We found that CD14(+) expressing monocytic MDSC isolated from transplant recipients were highly efficient in suppressing the proliferation of CD4(+) T cells in mixed leukocyte reactions. In addition, we observed that CD11b(+) CD33(+) HLA-DR(-) MDSC are capable of expanding Treg in vitro, and their accumulation overtime after transplantation linearly correlated with an increase in Treg in vivo. This is the first study to link the presence of MDSC with the emergence of Treg in vivo in transplant recipients, and to define the subpopulation of MDSC derived from transplant recipients responsible for generation of Treg. Further studies are necessary to determine the alloimmune regulatory function of MDSC in human transplant recipients.

Abstract
In these years, ordered mesoporous silica materials have shown promising applications in drug delivery system as drug carriers. These carriers with stable mesoporous structure, large surface area, good biocompatibility and tailored size of mesopores exhibit significant property of higher drug loading. However, silica-based mesoporous materials cannot control the release of the loaded drug without modifications. In this paper, we review the recent research work discussing functionalization of mesoporous materials by various components and methods for application in drug delivery systems. All the examples show that these functionalized mesoporous silica-based systems have great potential for a variety of drug delivery applications, specifically in the fields of the drug targeted and controlled delivery systems.

Abstract
Immune-mediated mechanisms have been implicated in liver pathogenesis and subsequent progression in hepatitis B virus (HBV) infection. Costimulatory molecules, the important regulators of immune responses, participate in the regulation of liver pathology in HBV infection. However, the role of B7-H3 (CD276, a new member of B7 family) in this process has not been investigated. In this study, we detected abundant soluble B7-H3 (sB7-H3) in the plasma of patients with chronic HBV infections. The increase of the plasma B7-H3 was associated with the progression of liver cirrhosis and accompanied by decreased expression of B7-H3 on hepatocytes. The identification analysis suggests that the plasma B7-H3 might be derived from the membrane-bound B7-H3 on hepatocytes. A functional study showed that immobilized (4Ig) B7-H3Ig fusion protein could inhibit TCR-induced proliferation and IFN-γ secretion of T cells, which could be partially blocked by soluble B7-H3flag fusion protein. These results suggest that the reduced expression of B7-H3 in the livers might temper the inhibition of T-cell responses mediated by B7-H3 expressed on hepatocytes and thus promote the hepatic inflammation and hepatitis progression in the chronic HBV-infected patients.

Abstract
Intracranial dermoid cysts with hemorrhage are fairly rare. Herein, we reported a 28-year-old female patient with a cerebellar dermoid cyst, which was found accidently on neuro-imaging after head trauma. MR scanning revealed that the lesion was located within the cerebellar vermis and was measured 3.5cm×3.9cm×3.0cm, with hyper-intensity on T1WI and hypo-intensity on T2WI. However, on CT imaging, it showed hyper-dense signals. It was removed completely via midline sub-occipital approach under surgical microscope. Histological examination proved it was a dermoid cyst with internal hemorrhage. In combination with literature review, we discussed the factors that might be responsible for the hemorrhage within dermoid cysts.

Abstract
Depletional induction therapies are routinely used to prevent acute rejection and improve transplant outcome. The effects of depleting agents on T-cell subsets and subsequent T-cell reconstitution are incompletely defined. We used flow cytometry to examine the effects of rabbit antithymocyte globulin (rATG) on the peripheral T-cell repertoire of pediatric and adult renal transplant recipients. We found that while rATG effectively depleted CD45RA+CD27+ naïve and CD45RO+CD27+ central memory CD4+ T cells, it had little effect on CD45RO+CD27- CD4+ effector memory or CD45RA+CD31-, CD45RO+CD27+ and CD45RO+CD27- CD8+ T cell subsets. When we performed a kinetic analysis of CD31+ recent thymic emigrants and CD45RA+/RO+ T cells, we found evidence for both thymopoiesis and homeostatic proliferation contributing to immune reconstitution. We additionally examined the impact of rATG on peripheral CD4+Foxp3+ T cells. We found that in adults, administration of rATG-induced peripheral expansion and new thymic emigration of T cells with a Treg phenotype, while CD4+Foxp3+ T cells of thymic origin predominated in children, providing the first evidence that rATG induces Treg in vivo. Collectively our data indicate that rATG alters the balance of regulatory to memory effector T cells posttransplant, providing an explanation for how it positively impacts transplant outcome.
