Abstract
In this study, a series of nanoporous HSiW@ZrO2 hybrids were synthesized using a zirconium metal-organic framework UiO-66 as a precursor towards biodiesel production. The structural and morphological properties of the obtained hybrids were characterized by the wide-angle XRD, FTIR, SEM, TEM, N2 adsorption/desorption, and NH3-TPD methods. Moreover, their catalytic activity in terms of calcination temperature during preparation was investigated, and the HSiW@ZrO2 hybrids calcinated at 300 °C exhibited the highest activity and the oleic acid (OA) conversion of 94.0% owing to the presence of the relatively high surface area, appropriate pore size and strong acidity. It was also revealed that the hybrids maintained as high as 82.0% even after nine cycles. Intriguingly, the nanoporous catalysts were found to exhibit excellent catalytic activity towards the esterification of the high acid value of Jatropha curcas oil.

Abstract
OBJECTIVE To investigate the effects of overexpression of long noncoding RNA (lncRNA) MEG3 on the proliferation and invasion of glioblastoma U251 cells by suppressing the expression of hypoxia inducible factor 1α(HIF1α). METHODS The expression of lncRNA MEG3 and HIF1α mRNA were examined in human fetal glial cells (HFGCs) and U251 cells using realtime quantitative PCR (qRT-PCR), and the expression of HIF1α protein was detected with Western blotting.U251 cells in normal culture or transfected with pcDNA3.1 vector (NC group) or pcDNA3.1-MEG3 vector via lipofectamine2000 were exposed to hypoxia for 12h, and the expressions of HIF1α mRNA and protein were detected with qRT-PCR and Western blotting, respectively.MTT assay and Transwell assay were employed to examine the influence of MEG3 overexpression on the proliferation and invasion of U251 cells. RESULTS The expression of MEG3 was significantly lower and HIF1α mRNA and protein expressions were significantly higher in U251 cells than in HFGCs (P < 0.05).In U251 cells, overexpression of MEG3 significantly decreased the mRNA and protein expressions of HIF1α(P < 0.05).Hypoxic exposure for 12h also resulted in significantly lowered expression of HIF1α protein in U251 cells (P < 0.05).Overexpression of MEG3 obviously suppressed the proliferation and invasiveness of U251 cells (P < 0.05). CONCLUSIONS MEG3 overexpression inhibits the proliferation and invasion of U251 cells through suppressing the expression of HIF1α mRNA and protein, suggesting that MEG3 may serve as a potential therapeutic target for glioblastomas.

Abstract
OBJECTIVE To summarize the experience of three Chinese cities (Wuhan, Shanghai and Haikou) and provide a reference for global efforts to combat COVID-19 spread among children. MATERIALS AND METHODS Through collecting the measures and outcomes of preventing and controlling COVID-19 in China's three hospitals, we compared the effect of different strategies. RESULTS From January to March 2020, the number of suspected and confirmed COVID-19 cases in Wuhan increased exponentially, and Wuhan Children's Hospital as a whole was transformed into a designated quarantine and treatment facility, which is the "Wuhan Model". Shanghai has more children's hospitals with better capabilities to tackle public health emergency. Besides, it is far away from Wuhan and had a small caseload. Children's Hospital of Fudan University, a facility in Shanghai to treat pediatric infectious diseases, is famous for its well-equipped building for infectious disease treatment and professional medical team, and therefore no major transformation was required. That is the "Shanghai Model". Haikou is located on an island. Amid the outbreak, large numbers of tourists and travelers from Hubei had already arrived in Haikou. Hainan Women and Children's Medical Center, as the only pediatric care hospital in Hainan Province, did not have a separate building for infectious disease treatment. After a citywide survey of the medical resources and facilities available, a temporarily idle hospital 3 kilometers away from Hainan Women and Children's Medical Center was requisitioned as the quarantine and treatment facility for pediatric cases. That is the "Hainan Model". The three models enabled the treatment of all suspected and confirmed cases and no fatality was reported. CONCLUSIONS The COVID-19 coping strategies for children should be designed according to the existing conditions of the local children's hospitals and the risk levels of the epidemic.

Abstract
Abstract
Background
Cyanotic congenital heart disease (CCHD) is a complex pathophysiological condition involving systemic chronic hypoxia (CH). A proportion of CCHD patients are unoperated due to various reasons. These patients remain CH all their lives and are at increased risk of heart failure as they age. Hypoxia activates cellular metabolic adaptation to balance energy demands by accumulation of hypoxia-inducible factor 1α (HIF-1α).
Purpose
The aim of this study was to determine the effect of CH on cardiac metabolism and function in CCHD patients and how it relates with age. The mechanistic role of HIF-1α in this process was investigated and potential therapeutic targets were explored.
Methods
CCHD patients (n=20) were evaluated for cardiac metabolism and function by positron-emission tomography/computed tomography and magnetic resonance imaging. Heart tissues collected during surgical intervention were subjected to metabolomic and protein analyses. CH rodent models were generated to enable continuous observation of changes in cardiac metabolism and function. The role of HIF-1α in cardiac metabolic adaptation to CH was investigated using genetically modified animals and isotope-labeled metabolomic-pathway tracing studies.
Results
Prepubertal CCHD patients had glucose-dominant cardiac metabolism and normal cardiac function. By comparison, among patients who had entered puberty, the level of myocardial glucose uptake and glycolytic intermediates were significantly lower, but fatty acids were significantly higher, along with decreased left ventricular ejection fraction. These clinical phenotypes were replicated in CH rodent models. In patients and animals with CH, myocardial HIF-1α was upregulated prior to puberty, but was significantly downregulated during puberty. In cardiomyocyte-specific Hif-1α-knockout mice, CH failed to initiate the switch of myocardial substrates from fatty acids to glucose, leading to inhibition of ATP production and impairment of cardiac function. Increased insulin resistance (IR) suppressed myocardial HIF-1α and was responsible for cardiac metabolic maladaptation under CH during puberty. Pioglitazone significantly reduced myocardial IR, restored glucose metabolism, and improved cardiac function in pubertal animals.
Conclusions
In CCHD patients, maladaptation of cardiac metabolism occurred during puberty, impairing cardiac function. HIF-1α was identified as the key regulator of cardiac metabolic adaptation under CH but its expression was suppressed by pubertal IR. The use of pioglitazone during puberty might help improve cardiac function in these patients.

Abstract
Objective To examine the method of least-square fitting for calibrating the palatal rugae boundary. Methods According to the distribution of the teeth, the feature points were selected; when they were fit, the boundary of the palatal rugae area was created, thereby constructing a mask. The mask was used to remove the part located outside the boundary and filter out the interference. Three samples were utilized for the experiments and analyses to come. Results To evaluate the quantitative results of the fitting curves, the correlation coefficients (r) of the samples and the relationship between the actual mean value and ideal mean value was obtained through six fitting processes. The differences between the actual mean and ideal mean were found to be significantly small (from 0.285 7 to 2.500 0) in the six fitting processes, with the range of r close to 1 (from 0.989 6 to 0.999 5). Conclusion The effect of the cubic polynomial fitting method adopted in this study was stable.The proposed boundary calibration method can effectively locate the palatal rugae boundary and remove the interference area, further promoting the practice of forensic identification.

Abstract
Detected in a variety of solid tumors, including lung cancer, the EML4-ALK fusion gene plays an important role in promoting the occurrence and development of cancer. The existing detection methods for EML4-ALK fusion gene are all targeted at surgical or post-sampling tumor tissues, which cannot achieve early detection and real-time monitoring; therefore, a minimally invasive ALK gene fusion detection system is explored and constructed. Vimentin, EpCAM, and EGFR antibodies were grafted, respectively, to prepare multi-site immunoliposome magnetic beads, so as to capture CTC in blood for RT-PCR detection, and then the feasibility of this method was verified by detecting the positive rate of the EML4-ALK fusion gene and clinical information in combination with WB and IHC. The prepared multi-site immunoliposome magnetic beads showed high specificity and stability, and the average proliferation rate and capture rate of cells were 95% and 85%, respectively. In clinical blood samples, the CTC level of the grade I (G1) patients before the operation was lower than grade 2 (G2), and that of grade II (G2) was significantly lower than grade III (G3), but the difference was not significant after the operation. The RT-PCR results of CTC and the RT-PCR, WB, and IHC results of tissues were highly consistent in the fusion gene detection, and the positive rate of ALK gene fusion in 60 lung cancer patients was 31.67% and 28.33% before and after the operation, mostly EML4-ALK (V3) gene fusion. The CTC-ALK gene fusion detection system constructed successfully could avoid the problem of difficult sampling and post-sampling complications, and truly achieve the minimally invasive biopsy, so it was of important clinical significance for the diagnosis and efficacy evaluation of lung.

Abstract
We have developed a protocol regarding the genomic characterization of the MICA gene by next generation sequencing (NGS). The amplicon includes the full length of the gene and is about 13 kb. A total of 156 samples were included in the study. Ninety‐seven of these samples were previously characterized at MICA by legacy methods (Sanger or sequence specific oligonucleotide) and were used to evaluate the accuracy, precision, specificity, and sensitivity of the assay. An additional 59 DNA samples of unknown ethnicity volunteers from the United States were only genotyped by NGS. Samples were chosen to contain a diverse set of alleles. Our NGS approach included a first round of sequencing on the Illumina MiSeq platform and a second round of sequencing on the MinION platform by Oxford Nanopore Technology (ONT), on selected samples for the purpose of either characterizing new alleles or setting phase among multiple polymorphisms to resolve ambiguities or generate complete sequence for alleles that were only partially reported in the IMGT/HLA database. Complete consensus sequences were generated for every allele sequenced with ONT, extending from the 5′ untranslated region (UTR) to the 3′ UTR of the MICA gene. Thirty‐two MICA sequences were submitted to the IMGT/HLA database including either new alleles or filling up the gaps (exonic, intronic and/or UTRs) of already reported alleles. Some of the challenges associated with the characterization of these samples are discussed.

Abstract
Shennong is the founder of cultivation, inventor of medicine. There are various recordation and legends about Shennong regional culture around the whole Chinese nation. The author studied the source of Shennong and Jingchu culture by comprehensively sorting relative literature recordation, citing unearthed materials in recent years as evidence, and found that the legends of Shennong is wide-spread in both western and southern China which corresponding to the origin of farming. What is more, a lot of delicate cultural relics and bambooslip and silk manuscripts have been found in Hubei and Hunan in recent years, which proved that Chu was not a land of barbarians in traditional view but an area with developed culture, and Shennong had a deep historic relation with Jingchu culture.

Abstract
Cellular internalization, delivery efficiency, and therapeutic efficacy of nanoparticles vary according to the microenvironmental complexity for tumor types. Adjusting their physicochemical properties, such as surface properties and size, has significant potential for dealing with such complexities. Herein, we prepare four types of pH-sensitive doxorubicin nanoparticles (DOX-D1, DOX-D2, DOX-W1, and DOX-W2 Nano) using simply changing reaction medium or reactant ratio. DOX-D1 and DOX-D2 Nano exhibit similar surface characteristics (surface coating and targeting ligand content) and different size, while both DOX-W Nano examples present similar surface characteristics and size. And they can re-self-assemble into smaller particles in blood-mimic conditions and the order of size is as follows: DOX-D1> DOX-D2 ≈ DOX-W Nano, and DOX-W Nano has a higher targeting ligand content than DOX-D Nano. Thus, the bioactivities in vitro and tumor microenvironment responses of DOX-D1, DOX-D2, and DOX-W1 are further investigated due to their different physicochemical properties. DOX-W1 Nano exhibits a higher cellular uptake, a stronger antiproliferation than DOX-D1 and DOX-D2 Nano attributed to its smaller size, and a higher targeting moiety content. Despite the similar sizes of DOX-W1 and DOX-D2, DOX-D2 Nano shows a greater in vitro blood-brain barrier (BBB) permeability related to its surface coating. Interestingly, DOX-D1 with suitable size and surface property can efficiently bypass the BBB and deliver to an intracranial glioma; in comparison DOX-W1 Nano has excellent targeting efficiency in subcutaneous tumors (glioma and breast cancer). Accordingly, DOX-D1 Nano is preferential for the treatment of intracranial glioma while DOX-W1 Nano exhibits potent killing ability for subcutaneous tumors. Our work suggests tailoring multiple physicochemical properties of nanoparticles can play a significant role in addressing tumor microenvironment complexity.

Abstract
COVID-19 is spreading almost all over the world at present, which is caused by the 2019 novel coronavirus (2019-nCoV). It was an epidemic firstly in Hubei province of China. The Chinese government has formally set COVID-19 in the statutory notification and control system for infectious diseases according to the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases. China currently is still struggling to respond to COVID-19 though intensive actions with progress made. The Burn Department of our hospital is one of sections with the highest infectious risk of COVID-19. Based on our own experience and the guidelines on the diagnosis and treatment of COVID-19 (7th Version) with other regulations and literature, we describe our experience with suggestions for medical practices for burn units during the COVID-19 outbreak. We hope these experiences and suggestions benefit our international colleagues during the pandemic of the COVID-19.

Abstract
BACKGROUND The INBUILD trial investigated the efficacy and safety of nintedanib versus placebo in patients with progressive fibrosing interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF). We aimed to establish the effects of nintedanib in subgroups based on ILD diagnosis. METHODS The INBUILD trial was a randomised, double-blind, placebo-controlled, parallel group trial done at 153 sites in 15 countries. Participants had an investigator-diagnosed fibrosing ILD other than IPF, with chest imaging features of fibrosis of more than 10% extent on high resolution CT (HRCT), forced vital capacity (FVC) of 45% or more predicted, and diffusing capacity of the lung for carbon monoxide (DLco) of at least 30% and less than 80% predicted. Participants fulfilled protocol-defined criteria for ILD progression in the 24 months before screening, despite management considered appropriate in clinical practice for the individual ILD. Participants were randomly assigned 1:1 by means of a pseudo-random number generator to receive nintedanib 150 mg twice daily or placebo for at least 52 weeks. Participants, investigators, and other personnel involved in the trial and analysis were masked to treatment assignment until after database lock. In this subgroup analysis, we assessed the rate of decline in FVC (mL/year) over 52 weeks in patients who received at least one dose of nintedanib or placebo in five prespecified subgroups based on the ILD diagnoses documented by the investigators: hypersensitivity pneumonitis, autoimmune ILDs, idiopathic non-specific interstitial pneumonia, unclassifiable idiopathic interstitial pneumonia, and other ILDs. The trial has been completed and is registered with ClinicalTrials.gov, number NCT02999178. FINDINGS Participants were recruited between Feb 23, 2017, and April 27, 2018. Of 663 participants who received at least one dose of nintedanib or placebo, 173 (26%) had chronic hypersensitivity pneumonitis, 170 (26%) an autoimmune ILD, 125 (19%) idiopathic non-specific interstitial pneumonia, 114 (17%) unclassifiable idiopathic interstitial pneumonia, and 81 (12%) other ILDs. The effect of nintedanib versus placebo on reducing the rate of FVC decline (mL/year) was consistent across the five subgroups by ILD diagnosis in the overall population (hypersensitivity pneumonitis 73·1 [95% CI -8·6 to 154·8]; autoimmune ILDs 104·0 [21·1 to 186·9]; idiopathic non-specific interstitial pneumonia 141·6 [46·0 to 237·2]; unclassifiable idiopathic interstitial pneumonia 68·3 [-31·4 to 168·1]; and other ILDs 197·1 [77·6 to 316·7]; p=0·41 for treatment by subgroup by time interaction). Adverse events reported in the subgroups were consistent with those reported in the overall population. INTERPRETATION The INBUILD trial was not designed or powered to provide evidence for a benefit of nintedanib in specific diagnostic subgroups. However, its results suggest that nintedanib reduces the rate of ILD progression, as measured by FVC decline, in patients who have a chronic fibrosing ILD and progressive phenotype, irrespective of the underlying ILD diagnosis.

Abstract
The natural killer group 2D (NKG2D) receptor and its ligands play important roles in immune surveillance. In this study, we observed that the average serum soluble MICA (sMICA) concentration of 174 hepatocellular carcinoma (HCC) patients was significantly higher than that in 80 healthy subjects (602.17 ± 338.15 vs. 72.26 ± 87.88 pg/ml, t = 3.107, P=0.002). The levels of serum sMICA in 44 HCC patients with initial levels above 400 pg/ml declined significantly after surgical removal of the liver cancer tissue (P<0.001). Moreover, the mean survival time of HCC patients who had sMICA above 400 pg/ml was significantly shorter than that HCC patients with lower sMICA levels (P<0.001). Using the reporter cell line (NKG2D-2B4) in which activation of the NKG2D receptor pathway results in GFP expression based on the stimulation of immobilized rMICA, we showed that the number of GFP-expressing cells decreased sharply in presence of sMICA. Upon adding sMICA, the release of cytokines IFN-γ, TNF-α, and IL-8 by NK cell line (NKL) under stimulation of immobilized rMICA was blocked. Using MICA-expressing cells as the target cells, we observed that about 80% of target cells were killed by NKL at E:T of 10:1, but in presence of sMICAhigh serum of HCC patients, the dead target cells were reduced to 30.8%. Compared in presence of sMICAlow serum from HCC patients, there were 63.7% of target cells dead (p=0.043). Thus, our data suggested that sMICA obstructs the activation of NKG2D pathway to protect tumor cells from NK cell-mediated cytotoxicity.

Abstract
According to the need of sustainable development, solid catalysts are critical materials for green biodiesel production. In this study, a hydrothermal method was used to develop a reusable and highly active Fe-BTC and UiO-66 metal–organic framework encapsulated Zr-doped polyoxometalate nano-hybrid catalysts (ZrSiW/Fe-BTC and ZrSiW/UiO-66) for the acid-catalyzed esterification of oleic acid with methanol. The structural and compositional characterization of the synthesized catalysts were characterized using various techniques such as Fourier transform infrared spectrometry (FT-IR), X-ray diffraction (XRD), nitrogen adsorption–desorption, scanning electron microscopy (SEM), and thermogravimetric (TG) and temperature programmed desorption (NH3-TPD) analysis. The as-prepared ZrSiW/UiO-66 had excellent catalytic activity in the esterification of oleic acid with methanol, higher than that of ZrSiW/Fe-BTC catalyst, owing to the fact that ZrSiW/UiO-66 nano-hybrids have high acidity, large specific surface area and pore volumes, and relatively large average pore sizes. Furthermore, the reusability and stability of nano-hybrids were also evaluated, and it was found that the stability of ZrSiW/UiO-66 catalyst was better. Zr-doped silicotungstic acid supported on MOFs were synthesized and used as a highly active nanocatalyst for esterification. Meanwhile, the nano-hybrids showed good reusability and may contribute to the economical benefits of biodiesel synthesis.![]()

Abstract
SummaryRenal clear cell carcinoma is prone to distant metastasis, especially in the head and neck, but it is rare to transfer to infratemporal fossa and pterygopalatine fossa. We reported a 62-year-old male patient with complains of numbness and burning sensation on the left side of the face for more than 3 months. Left kidney removal was performed 8 years ago due to renal cancer. Preoperative enhancement CT showed a large blood-rich occupation in the left nasopharyngeal and pterygopalatine with adjacent paranasal sinus and skull base bone destruction. Under the general anesthesia, the anterior lacrimal recess approach was used for tumor resection. Preoperative interventional embolization of the feeding artery, intraoperative pathology, frozen section showed metastasis of renal cell carcinoma, and postoperative immunohistochemical examination, confirmed metastatic renal clear cell carcinoma(infratemporal fossa and pterygopalatine fossa). The patients were transferred to the oncology department for further radiotherapy and chemotherapy.

Abstract
Objective: To check Forkhead box M1 (FoxM1) expression in nasal mucosal of chronic rhinosinusitis (CRS) patients and the effect of inflammatory factors on FoxM1 expression, in order to research the significance of FoxM1 in CRS. Methods: From January to October of 2018, 50 patients hospitalized in the Department of Otorhinolaryngology, Head and Neck Surgery, First Affiliated Hospital of Nanchang University were enrolled in this study. Twenty CRS patients with polyps (CRSwNP), 20 CRS patients without nasal polyps (CRSsNP) and 10 patients with simple deviation of nasal septum (the control groups) were selected. The expression of FoxM1 in nasal mucosa of these patients was detected by immunohistochemistry (IHC) and real-time fluorescent quantitative PCR (qRT-PCR). Meanwhile, HE stain was used to observe the pathologic changes in each sample. By establishing human nasal epithelium cells cultivating model in vitro and identifying via immumofluorescence method, experimental group and control group were set up, then activation factors including interleukin (IL)-1β, IL-4, IL-5, IL-17, interferon-γ (IFN-γ) and staphylococcal entemtoxin B (SEB) were added in the models after stabilizing passage, and qRT-PRC and Western blot method were applied to check the expressing change of FoxM1. Software SPSS 18.0 was used for statistical analysis. Results: HE stain showed that the mainly pathologic change in nasal mucosa of CRS patients with or without nasal polyp was mucosal epithelial cells, goblet cell and submucosal gland hyperplasia, accompanied by a large number of inflammatory cells infiltration. The result of IHC demonstrated that both of the expression of FoxM1 in nasal mucosal tissue of CRS patients in the CRSwNP and CRSsNP groups exceed that of the control group (80% vs 75% vs 20%, χ(2) value was 10.000, 8.213, respectively, all P<0.05); there was no difference of expression between the two groups of CRS patients (χ(2)=0.143, P>0.05). The result of qRT-PCR demonstrated that the expression of FoxM1 mRNA in nasal mucosa of CRSwNP and CRSsNP was increased compared with that of the control group (3.309±1.511 vs 3.261±1.336 vs 1.000±0.774, t value was 4.519, 4.928, respectively, all P<0.05), but the difference between the two groups of CRS patients had no statistic significance (t=0.107, P=0.909). Nasal mucosa epithelial cells cultivating models was established successfully. Q-RT PCR and Western blot were conducted after stimulation of 100 ng/ml IL-1β, IL-4, IL-5, IL-17, IFN-γ and SEB for 36 h, and the proteins expression levels of FoxM1 exceeded the groups without stimulation with statistic significance. Conclusions: The expression of FoxM1 in CRS increases and many types of cytokine can induce the increase of FoxM1 in human nasal epithelial cells. FoxM1 may participate in the process of pathogenesis in CRS.

Abstract
Objective:To investigate the expression of microtubuleassociated protein 1 light chain 3 beta(LC3) and eosinophil cationic protein in allergic rhinitis(AR) for further understanding of the pathogenesis of AR. Method: Twenty cases of normal nasal mucosa and 20 cases of AR nasal mucosa were collected. Histological changes of nasal mucosa were examined by hematoxylin and eosin(HE) staining. The expression of LC3 and ECP were measured by immunohistochemistry(IHC) and Western Blot(WB). Result: The tissue samples demonstrated a large number of eosinophils and lymphocytes infiltration in AR. IHC revealed that LC3 and ECP expression were higher in AR than in normal nasal mucosa(P<0.05). WB also showed that the relative expression levels of protein expression of LC3 and ECP were greater in AR than in controls. The expression level of LC3 was positively correlated with that of ECP protein in AR. Conclusion: LC3 and ECP were upregulated and positively correlated in AR, indicating that autophagy plays an important role in the toxicity of allergic rhinitis , which provides theoretical basis for the precise treatment of AR.

Abstract
The prevention of Botrytis cinerea infection and the study of grape seedlessness are very important for grape industries. Finding correlated regulatory genes is an important approach towards understanding their molecular mechanisms. Ethylene responsive factor (ERF) gene family play critical roles in defence networks and the growth of plants. To date, no large-scale study of the ERF proteins associated with pathogen defence and ovule development has been performed in grape (Vitis vinifera L.). In the present study, we identified 113 ERF genes (VvERF) and named them based on their chromosome locations. The ERF genes could be divided into 11 groups based on a multiple sequence alignment and a phylogenetic comparison with homologues from Arabidopsis thaliana. Synteny analysis and Ka/Ks ratio calculation suggested that segmental and tandem duplications contributed to the expansion of the ERF gene family. The evolutionary relationships between the VvERF genes were investigated by exon-intron structure characterisation, and an analysis of the cis-acting regulatory elements in their promoters suggested potential regulation after stress or hormone treatments. Expression profiling after infection with the fungus, B. cinerea, indicated that ERF genes function in responses to pathogen attack. In addition, the expression levels of most ERF genes were much higher during ovule development in seedless grapes, suggesting a role in ovule abortion related to seedlessness. Taken together, these results indicate that VvERF proteins are involved in responses to Botrytis cinerea infection and in grape ovule development. This information may help guide strategies to improve grape production.

Abstract
OBJECTIVE Larotaxel is a new chemical structure drug, which has not been marketed worldwide. Accordingly, the standard identification and quantification methods for larotaxel remain unclear. The spectrometric analyses were performed for verifying weight molecular formula, molecular weight and chemical structure of larotaxel. Besides, a quantification method was developed for measuring larotaxel in the liposomes. METHODS The molecular formula, molecular weight and chemical structure of larotaxel were studied by using mass spectrometry (MS), infra-red (IR), nuclear magnetic resonance (NMR) and ultraviolet-visible (UV-vis) spectrometric techniques. The absorption wavelength of larotaxel was investigated by UV-vis spectrophotometry full-wavelength scanning. Besides, a quantification method was developed by high performance liquid chromatography (HPLC), and then validated by measuring the encapsulation efficacy of larotaxel liposomes. RESULTS The four spectral characteristics of larotaxel were revealed and the corresponding standard spectra were defined. It was confirmed that larotaxel had the structure of tricyclic diterpenoids, with the molecular formula of C45H53NO14, the molecular weight of 831.900 1, and the maximum absorption wavelength of 230 nm. The quantitative method of larotaxel was established by using HPLC with a reversed phase C18 column (5 μm, 250 mm×4.6 mm), a mobile phase of acetonitrile-water (75:25, volume/volume), and a detection wavelength of 230 nm. The validation study exhibited that the established HPLC method was stable, and had a high recovery and precision in the quantitative measurement of larotaxel in liposomes. In addition, a new kind of larotaxel liposomes was also successfully prepared. The particle size of the liposomes was about 105 nm, with an even size distribution. And the encapsulation efficiency of larotaxel in the liposomes was above 80%. CONCLUSION The present study offers reference standard spectra of larotaxel, including MS, IR, NMR, and UV-vis, and confirms the molecular formula, molecular weight and chemical structure of larotaxel. Besides, the study develops a rapid HPLC method for quality control of larotaxel liposomes.

Abstract
A single genome gives rise to diverse tissues through complex epigenomic mechanisms, including N6-methyladenosine (m6A), a widespread RNA modification that is implicated in many biological processes. Here, to explore the global landscape of m6A in human tissues, we generated 21 whole-transcriptome m6A methylomes across major fetal tissues using m6A sequencing. These data reveal dynamic m6A methylation, identify large numbers of tissue differential m6A modifications and indicate that m6A is positively correlated with gene expression homeostasis. We also report m6A methylomes of long intergenic non-coding RNA (lincRNA), finding that enhancer lincRNAs are enriched for m6A. Tissue m6A regions are often enriched for single nucleotide polymorphisms that are associated with the expression of quantitative traits and complex traits including common diseases, which may potentially affect m6A modifications. Finally, we find that m6A modifications preferentially occupy genes with CpG-rich promoters, features of which regulate RNA transcript m6A. Our data indicate that m6A is widely regulated by human genetic variation and promoters, suggesting a broad involvement of m6A in human development and disease.

Abstract
Objective: To evaluate the efficacy and safety of transbronchial lung cryobiopsy (TBCB) and conventional transbronchial lung biopsy (TBLB) in the diagnosis of interstitial lung diseases(ILD). Methods: A prospective, self-control study was conducted during January 2017 and April 2017 in First Affiliated Hospital of Guangzhou Medical University. A total of 25 patients [male 16, female 9; mean age (51±13) years, range 24 to 70 years] with inconclusive diagnosis of interstitial lung diseases were sequentially enrolled. In the study, TBCB (TBCB group) and TBLB (TBLB group) were performed successively under general anesthesia in all patients. The size of biopsy specimens, the duration of procedures, complications and pathological results were recorded. Gaussian distribution data were compared between 2 groups by using Student's t test, while abnormal distribution data were compared by using Wilcoxon rank sum test. The incidences of bleeding and pathologic diagnostic yield between the 2 groups were compared by using Pearson chi-square test. A P-value< 0.05 was assumed to be statistically significant. Results: The specimen sizes of TBCB group and TBLB group were (12.3+ 4.9) and (3.1+ 1.9) mm(2) respectively (t=-18.268, P=0.000). The duration of procedures was (7.8±3.2) and (5.4±2.1)min respectively (Z=-3.001, P=0.003). In TBCB group, the diagnostic yield was 72% (18/25), with valuable pathological results in 2 cases (8%), but in 5 cases (20%) it failed to provide valuable pathological results. In TBLB group, the diagnostic yield was 12% (3/25). There were no useful pathological results in other 22 cases. The difference in the rate of useful pathological results between TBCB group and TBLB group was significant (χ(2)=20.779, P=0.000). There was no pneumothorax or severe bleeding. The rate of mild to moderate bleeding in TBCB group and TBLB group was 47.2%(50/106) and 18.9%(20/106) (χ(2)=19.195, P=0.000) respectively. Conclusion: TBCB is superior to TBLB for lung biopsy as indicated by larger sample size, higher diagnostic yield and less complication. TBCB is valuable for the diagnosis of ILD.

Abstract
BACKGROUND Several previous researches had found artery stiffness associated skeletal muscle mass, but not considering muscle strength and physical performance, which also were compositions of sarcopenia. This study aims to reveal the relationship of artery stiffness and sarcopenia using the Asian Working Group for Sarcopenia criteria. METHODS Study was performed on 1002 Chinese community dwelling participants aged ≥65 years from November 2016 to March 2017. Body composition, muscle strength, physical performance, and brachial-ankle pulse wave velocity (baPWV) considering as artery stiffness index were measured. RESULTS In multiple regression analysis, baPWV was associated with handgrip (β=-0.13, P=0.04) and Relative skeletal muscle mass index (ASM/Ht2) (β=-0.02, P<0.01), but not with 4-meter velocity (P=0.21). Multiple logistic regression analysis showed that 1-SD (3.50m/s) increased in baPWV was still associated with a 11% (CI, 4%-20%; P<0.01) higher odds of being sarcopenia. In the gender subgroup analysis, the relationship of baPWV and sarcopenia remain significant in men (OR, 1.23; 95% CI, 1.07-1.42, P<0.01), but not in women (P=0.07). CONCLUSIONS High brachial-ankle pulse wave velocity is associated with sarcopenia in Chinese community-dwelling elderly, with gender differences.

Abstract
Objective:To retrospectively analyze the characteristics of 100 cases with Dix-Hallpike test induced nystagmus, especially the vertical downward component.Method:One hundred cases with positive Dix-Hallpike test between December 2017 and January 2018 were included in this study. Dix-Hallpike test and roll test were performed in all patients, and the max slow phase velocity (SPV), latency and duration of positional nystagmus were analyzed with SPSS 22.0 software.Result:According to the difference in the direction and duration of the nystagmus in the head-hanging position on Dix-Hallpike test, 100 patients were classified into 9 types. When only the vertical components were considered, 56 cases presented with bilateral or unilateral vertical upward component, among which 52 cases had unilateral torsional with vertical upward component, 4 cases had bilateral torsional with vertical upward component; 7 cases presented with vertically upward in one side and the vertically downward in the other side; 47 cases presented with bilateral or unilateral vertical downward component. In addition, 8 cases showed the reverse phase nystagmus. Of the 100 patients with positive Dix-hallpike, 20 cases were positive in roll test and 5 cases showing horizontal nystagmus and 15 cases showing torsional and vertical nystagmus.Conclusion:Vertical component in the positional nystagmus was common, and care should be taken to interpret the nystagmus into the underlying disorder.

Abstract
Objective:To investigate the expression of growth factor differentiation factor 15 (GDF15) in the nasal mucosa of patients with chronic rhinosinusitis (CRS) and its relationship with mucin 5AC(MUC5AC).Method:Fifteen patients with CRS and nasal polyps, 15 patients with CRS without nasal polyps and 15 patients with normal nasal mucosa were enrolled in the study. Hisological changes of sinonasal mucosa were examined by hematoxylin and eosin (HE) stainding. The expression of total mucins was evaluated by periodic acid Schiff staining(PAS). And the expression of GDF15 and MUC5AC were measured by immunohistochemistry (IHC), and reverse transcription polymerase chain reaction (RT-PCR).Result:The tissuse samples demonstrated mucaosal thicking, goblet cell hyperplasia, glandular hyperplasia and inflammatory cell infiltration in CRSwNP and CRSsNP. IHC revealed that GDF15 and MUC5AC expression higher in CRSwNP and CRSsNP than in normal sinus mucosa (P< 0.05). qRT-PCR also displays that the relative expression levles of mRNA exprssion of GDF15 and MUC5AC were higher in CRSwNP and CRSsNP than in controls.And the expression level of GDF15 was positively correlated with that of MUC5AC mRNA in CRS.Conclusion:GDF15 and MUC5AC were upregulated in CRS with or without nasal polyps, indicating that GDF15 is an important factor in the process of hypersecretion of MU5AC in CRS.

Abstract
We retrospectively analyzed 2 patients of unilateral Meniere's disease with downbeat nystagmus. Audiometric test, the Dix-Hallpike maneuver and the supine roll test were performed. Both patients presented with spontaneous nystagmus with downbeat components, and downbeat components were exaggerated by Dix-Hallpike maneuver. Spontaneous and positional nystagmus with downbeat component can occur in Meniere's disease, which may be resulted from excitation of three semicircular canals.

Abstract
Circular RNAs (circRNAs) are a new class of RNAs that can be used as biomarkers in clinical blood samples. However, little is known about circRNAs' diagnostic values for rheumatoid arthritis (RA). In this study, the hsa_circ_0054189, hsa_circ_0008675, hsa_circ_0082689, hsa_circ_0082688, hsa_circ_0010932, hsa_circ_0002473 and hsa_circ_0044235 in peripheral blood were determined by quantitative reverse transcription–polymerase chain reaction (qRT–PCR). For hsa_circ_0044235, only one abnormal expression circRNAs in peripheral blood was selected as a targeted circRNA to explore the diagnostic value for RA. Our work demonstrated that the hsa_circ_0044235 in peripheral blood was decreased significantly in RA patients. The hsa_circ_0044235 in peripheral blood from RA patients did not correlate with C‐reactive protein (CRP), erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), anti‐citrullinated protein antibodies (ACPA) or disease activity score 28 (DAS28). Receiver operating characteristic (ROC) curve analysis suggested that the hsa_circ_0044235 in peripheral blood has significant value in the diagnosis of RA. The risk score based on hsa_circ_0044235 in peripheral blood also distinguished significantly the patients with RA from systemic lupus erythematosus (SLE). This study suggests that the hsa_circ_0044235 in peripheral blood may be a potential biomarker of patients with RA.

Abstract
NK cells are important innate cytotoxic lymphocytes that have potential in treatment of leukemia. Engagement of NKG2D receptor on NK cells enhances the target cytotoxicity. Here, we produced a fusion protein consisting of the extracellular domain of the NKG2D ligand MICA and the anti-CD20 single-chain variable fragment (scfv). This recombinant protein is capable of binding both NK cells and CD20+ tumor cells. Using a human NKG2D reporter cell system we developed, we showed that this fusion protein could decorate CD20+ tumor cells with MICA extracellular domain and activate NK through NKG2D. We further demonstrated that this protein could specifically induce the ability of a NK cell line (NKL) and primary NK cells to lyse CD20+ leukemia cells. Moreover, we found that downregulation of surface HLA class I expression in the target cells improved NKL-mediated killing. Our results demonstrated that this recombinant protein specifically lyses leukemia cells by NK cells, which may lead to development of a novel strategy for treating leukemia and other tumors.

Abstract
Objective: To evaluate the serological diagnostic value of Mycobacterium (M.) tuberculosis four new antigens Rv0432, Rv0674, Rv1566c and Rv1547. Methods:Rv0432, Rv0674, Rv1566c and Rv1547 were amplified from M. tuberculosis strain H37Rv genomic DNA by using PCR, among which Rv1547 was divided into two segments for amplification (Rv1547-1 and Rv1547-2). The segments were cloned into expression vector PET-32a while the recombinant proteins were purified by affinity chromatography. Serums were incubated with BL21 (DE3) proteins. Antibodies IgG against M. tuberculosis were tested with 151 serum samples (41 healthy people and 110 TB patients) by using ELISA. The diagnostic efficiency of antigens was analyzed by means of receiver operating characteristic curve. Difference of the objective proteins in TB patients and healthy controls was compared by t-test. Results: Recombinant antigens Rv0432, Rv0674, Rv1566c, Rv1547-1 and Rv1547-2 were successfully expressed and purified. Results from ELISA showed that the sensitivity, specificity, positive predictive value, negative predictive value, Youden index and area under the curve of Rv0432, Rv0674, Rv1566c, Rv1547-1 and Rv1547-2, as 43.64%-92.73%, 80.49%-92.68%, 0.92-0.94, 0.38-0.80, 0.363-0.732 and 0.649-0.915. All the objective proteins showed significantly higher antibody levels in TB patients, when compared to the healthy controls (P<0.000 1). Conclusion: The newly identified antigens Rv0432, Rv0674, Rv1566c, Rv1547-1 and Rv1547-2 all performed well when being used for TB serological diagnosis, thus were expected to be new candidate antigens used for TB diagnosis.

Abstract
Objective:To explore the epidemiological characteristics and to help accomplish accurate diagnosis and treatment strategies by analyzing the composition and clinical features of various diseases with acute constant vertigo.Method:We retrospectively analyzed medical records (including name, sex, age, diabetes, hypertension, history of vertigo, family history, etc.),otoneurological examination, vestibular function tests and radiological examination of patients with acute vestibular syndrome.We classified various diseases according to diagnostic criteria, and then analyze the clinical data.Result:A total of 77 patients with acute vestibular syndrome were enrolled in this study. It included 34 patients with vestibular neuritis, 18 patients with sudden sensorineural deafness with vertigo, 1 with vestibular schwannoma, 6 with acute vestibular syndrome with migraine, 3 with Hunter syndrome with vertigo, 1 with vertigo after trauma,1 with acute bilateral vestibulopathy, 9 with acute vertigo syndrome with other etiology, 3 with acute labyrinthitis, and 1 with posterior circulation infarction. There were no significant differences in the age and course of disease between different etiologies (P>0.05). There were statistical differences between vestibular neuritis and sudden sensorineural deafness with vertigo among head impulse test and hearing loss (P<0.05). There was significant difference in hearing between sudden sensorineural deafness with vertigo and acute vertigo syndrome (P<0.05).Conclusion:Most of the acute vestibular syndrome patients attending the otorhinolaryngology head and neck surgery clinic were peripheral acute vestibular syndrome, vestibular neuritis, and sudden sensorineural deafness with vertigo.Patients with acute vestibular syndrome with migraine are not rare, and central vertigo can also be seen.

Abstract
AIM Rheumatoid arthritis (RA) as an inflammatory autoimmune disease affects the synovial joints as well as other organs and tissues. Since aberrant expression of MIC molecules has been observed in RA patient, MIC genotypes might play certain roles in the development of RA. METHOD To explore the association of MICA and MICB polymorphisms with RA in a Han Chinese population in Hainan Island, samples from 172 RA and 137 healthy controls were genotyped for MICA and MICB. RESULTS Our results indicated that MICB*002 and MICB*014 were less frequent in RA patients than in controls (P = 0.000, 0.005) while there were higher percentages of RA patients carrying MICA*009 and MICA*A6 (P = 0.005). CONCLUSION Different MIC variants might modulate the autoimmune reaction differently in RA disease and therefore serve as protective or risk factors.

Abstract
Objective To evaluate the pathological features and define the optimal surgical margins (SM) of nephron-sparing surgery (NSS) for kidney neoplasms 4–7 cm (stage pT1b) on preoperative imaging. Materials and methods The retrospective study included 748 patients who were diagnosed stage pT1b renal tumors and underwent either radical nephrectomy (RN, n = 475) or NSS (n = 273) from January 2004 to March 2017. The tumor size, pathological subtype, Fuhrman grade, status of peritumoral pseudocapsule (PC) and tumor multifocality were recorded. The relationship between peritumoral PC and positive SM was calculated statistically by Fisher’s exact probability test. Results The mean tumor diameter was 5.4 cm (range: 4.1–7.0 cm), 65 (8.7%) cases were discovered with multifocal lesions and 686 (91.7%) were surrounded with peritumoral PC in all 748 specimens. 57 (8.3%) of 686 cases were proved with tumor infiltrated beyond PC [infiltration (+)], and the presence of PC infiltration (+) was significantly correlated with positive SM (p = 0.016). The infiltrative depth of tumor cells into renal parenchyma beyond PC was all limited in 3 mm and the proportion of ≤ 1, 1–2 and 2–3 mm was 21.1% (12/57), 59.6% (34/57) and 19.3% (11/57), respectively. Conclusions Our report indicates a 3 mm excisional margin is acceptable to ensure negative SM when operating NSS on stage pT1b kidney neoplasms.

Abstract
Both systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) diseases are related to the genetic and environmental factors, causing damage to the skin. The mutations of keratin 1 gene (KRT1) were reported to associate with skin diseases. The single-nucleotide polymorphism (SNP, rs14024) and the indel polymorphism (cds-indel, rs267607656), consisting mostly of the common haplotypes and could be used for genotyping of KRT1. We used the PCR with sequence specific primers (PCR-SSP) to determine the genotype of KRT1 in 164 SLE, 99 SSc patients, and 418 healthy controls. The results showed that the mutant with G at SNP rs14024 was associated with the high risk to SLE (p = 6.48×10-5) and SSc (p = 8.75×10-5), while the deletion allele at rs267607656 was associated with the low risk to SSc (p = 4.89×10-4) comparing to the normal controls. Haplogenotype, Del-/MU+ was associated with high susceptibility to SLE (OR = 1.87, p = 0.001) and SSc (OR = 2.29, p = 2.34×10-4). In contrast, the Haplogenotype Del+/MU- was associated with resistance to SLE (OR = 0.35, p = 6.24×10-5) and SSc (OR = 0.34, p = 0.001). This study demonstrates that the variations in KRT1 and the specific polymorphism of KRT1 in this Chinese Han population are associated with autoimmune diseases SLE and SSc. Typing KRT1 might be helpful to identify SLE and SSc patients.
