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
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
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
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
Exosomes are nanovesicles secreted by a variety of living cells, which are involved in biological processes such as inflammation,antigen presentation,tumor invasion, and cell differentiation.They are a new mechanism of intercellular communication in the body.Airway chronic inflammatory diseases such as chronic rhinosinusitis,allergic rhinitis, chronic obstructive pulmonary disease,bronchial asthma,etc.are non-specifically involved in airway intrinsic cells,inflammatory cells and inflammatory factors under various internal and external stimuli.Heterotropic inflammatory disease.Exosomes contain a variety of protein,RNA,lipid and other signal transmission media, the are important to chronic inflammation of the airways,and chronic rhinosinusitis,nasal polyps,bronchial asthma,and chronic obstructive pulmonary disease.The occurrence and development of chronic inflammation of the airway is closely related. This article summarizes the current research progress of exosomes and discusses their role in chronic inflammatory diseases of the airways.

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
PURPOSE We summarized the evidence on the effects of heat and cold exposures on mortality in China. We included studies published on this topic in both Chinese and English, thereby filling a gap in knowledge using data from a country that consists of one-fifth of the world's population. METHODS We conducted a systematic search of peer-reviewed studies on the association between daily mean temperature and mortality published from 2001 up to July 2018. We searched one Chinese database (China National Knowledge infrastructure, http://www.cnki.net) and three English databases (PubMed, Scopus, Web of Science). We converted the effect estimates of heat/cold to rate ratios (RRs) associated with 1° increase/decrease beyond the heat/cold reference temperatures. For studies that provided lag-specific estimates, we used both the maximum and minimum of RR estimates. We calculated summary effect estimates for all-cause and cause-specific mortalities, as well as RRs stratified by sex, age, and socioeconomic status. We also investigated patterns of heat and cold adaptation at different latitudes, and at different reference temperatures. RESULTS In total, 45 articles were included in this systematic review. For every 1° temperature increase/decrease beyond reference points, the rate of non-accidental mortality increased by 2% (RR, 1.02; 95% confidence interval (95% CI [1.01-1.02]) for heat and 4% (RR, 1.04; 95% CI [1.03-1.04]) for cold, respectively; the rate of cardiovascular mortality increased 3% (RR, 1.03; 95% CI [1.03-1.04]) for heat and 6% (RR, 1.06; 95% CI [1.04-1.07]) for cold; the rate of respiratory mortality increased 2% (RR, 1.02; 95% CI [1.01-1.03]) for heat and 2% (RR, 1.02; 95% CI [1.00-1.04]) for cold; the rate of cerebrovascular mortality increased 2% (RR, 1.02; 95% CI [1.02-1.03]) for heat and 3% (RR, 1.03; 95% CI [1.02-1.04]) for cold. We identified a variation in optimal temperature range related to latitude of the residential area, and differences in people's capability to adapt to heat versus cold. CONCLUSION We found consistent evidence of the association between temperature and mortality, as well as evidence of patterns in human adaptation, and we discussed the implications of our findings.

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.

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 explore the expression of Forkhead box protein m1(Foxml) in the sinus mucosa of patients with chronic rhinosinusitis(CRS) and the relationship between Foxm1 and MUC5AC for further understanding of the pathogenesis of CRS.Method:We obtained the sinus mucosa from 25 CRS with polyps(CRSwNP) patients and 25 CRS without polyps (CRSsNP) patients as two experimental groups.Nasal mucosa from 15 normol cases were obtained as control group.We used HE,Periodic acid-schiff staining to observe the histopathological change of each sample.The expression of Foxm1 and MUC5AC were determined by immunohistochemistry(IHC) and qRT-PCR in each group.We also analysed the relationship between Foxm1 and MUC5AC.Result:The HE and PAS staining showed that in the CRSwNP and CRSsNP patients,the main histopathological features was the hyperplasia of goblet cell,inflammatory cell and submucosal gland.IHC showed that Foxm1 and MUC5AC expression were higher in CRSwNP and CRSsNP compared with normal sinus mucosa.qRT-PCR also revealed that Foxm1 and MUC5AC expression was higher in CRSwNP and CRSsNP than in normal mucosa(P<0.05).Foxm1 and MUC5AC had a significant positive correlation.Conclusion:The expressions of Foxm1 and MUC5AC were increased in CRS,and Foxm1 may play an important role in the process of hypersecretion of MUC5AC in CRS.

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
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 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
Porcine postweaning multisystemic wasting syndrome (PMWS) caused by porcine circovirus type 2 (PCV2) is a disease causing severe economic losses annually worldwide to the pig industry. PCV2 infection was first reported in China in 2000, and currently has three major genotypes, PCV2a, b and d, circulating in this country. To further elucidate the origin and prevalence of PCV2 in China, 123 clinical pig tissue samples collected in 25 provinces between 1990 and 1999 were analysed by PCV2-specific PCR, resulting in identification of 23 PCV2 strains collected between 1996 and 1999. Phylogenetic analysis based on the nucleotide sequences of open reading frame 2 (ORF2) showed that 20 of the 23 grouped within PCV2a, while the remaining three strains formed an independent clade, so far unreported and therefore named PCV2f. This genotype shared lower sequence identity with other known genotypes. This study provides further understanding of the genetic diversity and evolution of PCV2 and has tracked PCV2 infection in China back to 1996 rather than 2000.

Abstract
MICA/MICB gene polymorphisms are related to several cancers and infectious diseases, but there are no reports on the association between MICA/MICB gene polymorphisms and respiratory syncytial virus (RSV) infection. To clarify the association between MICA/MICB gene polymorphisms and infection of RSV in children, we collected fresh blood samples from paediatric patients with and without pneumonia after RSV infection. The MICA/MICB alleles were characterized by PCR sequence-specific primers (PCR-SSP) and PCR sequence-based genotyping (PCR-SBT), and then, the frequency of the MICA/MICB alleles and haplotypes was calculated. The results showed that the frequencies of MICA*002:01 and MICA-A9 in RSV-infected patients were significantly lower than in controls (9% vs. 20%, pc = 0.04). The allele frequency of MICA*002:01 in pneumonia patients (8%) and nonpneumonia patients (9%) was significantly lower than in controls (20%, pc = 0.02). MICA*002:01-MICB*008(Δrel = 0.616), MICA*009-MICB*016 (Δrel = 0.506), and MICA*045-MICB*014 (Δrel = 0.700) showed linkage disequilibrium in patients infected with RSV. The haplotype frequency of MICA*002:01-MICB*005:02 in RSV-infected patients was significantly lower than in controls (10% vs. 16%, pc = 0.033). In conclusion, allele MICA*002:01/A9 and haplotype MICA*002:01-MICB*005:02 were negatively associated with RSV respiratory tract infections.

Abstract
We retrospectively analyzed 3 middle-aged male patients of primary malignant tumor of uvula. There was a long history of smoking and drinking for the patients. All of them came to the hospital with the syptoms of pharyngeal foreign body sensation and two of them had pharyngeal sore. The patients appeared well, new neoplasm at the apex of the uvula. Diameter of 2 cases were less than 1 cm without invading the midline of the soft palate. Another patient's diameter was more than 1 cm with invading the midline of the soft palate. Preoperative pathology diagnosis of 3 patients was squamous cell carcinoma of uvula. The pharyngeal CT of the patient with invading the midline of the soft palate showed nodules at the end of the soft palate, obviously enhancement and small lymph node in left neck.

Abstract
OBJECTIVE To investigate the interproximal contact(IC) loss rate and the associated risk factors of IC loss between posterior fixed implant prostheses and the adjacent teeth. METHODS Ninety-seven posterior fixed implant prostheses including 165 IC in 78 patients(34 men, 44 women) between 23 and 76 years of age were investigated. The period after restoration ranged from 1 to 44 months. The IC between implant prostheses and adjacent teeth was evaluated using a 30-μm-thick contact gauge and dental floss, and the IC was regarded as lost when the gauge or dental floss was inserted into an IC without any resistance at follow-up visits. The state of IC, region of implant prostheses, the condition of opposing dentition, the vitality of the adjacent teeth and the time interval of tooth loss were also confirmed for correlation analysis. RESULTS All 78 patients finished follow-up examination. Forty-eight of 165 IC(29%) were regarded as lost. The IC loss rate at the mesial aspect[75%(36/48)] was significantly greater than that at the distal aspect[25%(12/48)](χ(2)=7.344,P=0.007). The difference between IC loss rate in the maxilla[46% (22/48)] and that in the mandible[54%(26/48)] was not significant(χ(2)=2.992,P=0.084). Free-end[hazard ratio (HR)=2.870], and the time interval of tooth loss(HR=0.919) affected the loss of IC significantly(P<0.05, Cox regression analysis). CONCLUSIONS Loss of IC between posterior fixed implant prostheses and adjacent teeth was one of biological complications, which was observed frequently at follow-up visits. Patients who have the free-end fixed implant prostheses, or undergo short time interval of tooth loss before restoration may have high risk of the IC loss.

Abstract
Objective: To investigate the effect of noninvasive proportional assist ventilation (PAV) on respiratory work in chronic obstructive pulmonary disease(COPD) patients, in comparison to noninvasive pressure support ventilation(PSV). Methods: Ten severe COPD patients with hypercapnia during acute exacerbation were examined. The baseline inspiratory pressure of PSV (PS) and the assistance level of PAV(PA) were titrated by patients' tolerance. In addition to the baseline PS and PA, an additional decrease by 25% (PS-=75% PS, PA-=75% PA) or increase by 25% (PS+ =125% PS, PA+ =125% PA) of the assist level were applied to the patients. After the assessment of unassisted spontaneous breathing (SB), the patient was placed on the 6 levels of noninvasive-PSV and noninvasive-PAV in random sequence. Each level lasted at least 20 minutes. Respiratory rate (RR), tidal volume (Vt), and respiratory work(Wex, Wip and Wv) were measured. Asynchrony index (AI) was calculated. Results: During ventilation, Vt was significantly higher with each assist level than with SB. The Vt was significant increased with PS+ than with PA+ . An increase in expiratory work(Wex) and decrease in inspiratory work(Wip) were observed respectively, with the increasing assist level. The inspiratory muscles assessed by Wip were more unloaded at PS compared with PA [PS: (1.59±1.27) J/min vs PA: (4.99±3.48) J/min P<0.01]. However, the Wex was significantly higher with PS+ than with PA+ [PS+ : (1.17±0.54) J/min vs PA+ : (0.49±0.56)J/min, P<0.01]. The AI was increased with the increasing assist level of PSV [PS-: (0.46±0.57)%, PS: (1.36±1.24)% PS+ : (5.26±4.77)]. No asynchrony events were observed at PA- and PA. "Runaway" (expiratory asynchrony) was observed during PA+ [AI: (2.62±2.72)%]. Conclusions: Noninvasive-PAV can increase the Vt and decrease the Wip of the COPD patients with hypercapnia and avoid the over-assistance. The "Runaway" will occur at assist level higher than that set by tolerance. Physiological data can monitor the patient's responses and the ventilator-patient interaction, which may provide objective criteria for ventilator setting.

Abstract
A systematic study was conducted to identify reliable reference genes for normalization of gene expression analysis in the blotched snakehead Channa maculata under normal physiological conditions. Firstly, the partial complementary (c)DNA of nine candidate reference genes (actb, tmem104, ube2l3, ef1α, churc1, tmem256, rpl13a, sep15 and g6pd) were cloned from C. maculata. The expression levels of these genes were then assessed in embryos of different developmental stages and various tissue types of adult fish using quantitative real-time (qrt-)PCR. RefFinder algorithm was used to evaluate the expression stability of these genes based on their cycle-threshold (Ct ) values in the qrt-PCR analysis. Results showed that there was no single best reference gene for all stages of embryos and adult tissues tested. Furthermore, it was found that, among the nine candidate genes tested, actb and tmem104 were the most stable reference genes across adult tissue types, while sep15 and tmem256 were the most stable ones across developmental stages of embryos. These stable reference genes are recommended for normalization of gene expression analysis in C. maculata.

Abstract
Objective: To investigate the relationship between D-cycloserine resistance and the gene mutations of alrA, ddlA and cycA of Mycobacterium (M.) tuberculosis, as well as the association between D-cycloserine resistance and spoligotyping genotyping. Methods: A total of 145 M. tuberculosis strains were selected from the strain bank. D-cycloserine resistant phenotypes of the strains were determined by the proportion method and the minimal inhibitory concentration was determined by resazurin microtiter assay. PCR amplification and DNA direct sequencing methods were used for the analysis of gene mutations. Relationship between the resistance phenotype and genotype was analyzed by chi-square test. Results: Of the 145 clinically collected strains, 24 (16.6%) of them were D-cycloserine resistant and 121 (83.4%) were sensitive. There were only synonymous mutations noticed on alrA, ddlA and cycA in sensitive strains. Of the 24 D-cycloserine resistant strains, 3 (12.5%) isolates' cycA and 1 (4.2%) isolates' alrA happened to be non-synonymous mutations, in which the codes were 188, 318 and 508 of cycA, and 261 of alrA, respectively. Results on drug sensitivity tests confirmed the minimal inhibitory concentration of the mutant strains were all increased to some degrees. The D-cycloserine resistant rates of 88 Beijing genotype and 57 non-Beijing genotype strains were 20.5% and 10.5% , respectively, but with no statistically significant difference (χ(2) =2.47, P>0.05). Conclusions: The non-synonymous mutations of alrA and cycA might contribute to one of the mechanisms of M. tuberculosis D-cycloserine resistance. M. tuberculosis Beijing genotype or non-Beijing genotype was not considered to be associated with the D-cycloserine resistance.

Abstract
Oral biofilms are mixed-species microbial communities, and their uncontrolled outgrowth can express as oral diseases. Antimicrobial peptides represent alternative classes of antimicrobials that exhibit selectivity for prokaryotes. We wanted to test the effect of a synthetic decapeptide antimicrobial, KSL, on the development of oral biofilms formed by isolated human salivary bacteria. We used differential interference contrast microscopy, coupled with a dual-flow cell system, to determine the effect of KSL on oral biofilm development. We used reductions of viable counts and confocal microscopy to assess the bactericidal activity of KSL on mature oral biofilms. KSL effectively blocked biofilm development. A significant effect on the viability of mature biofilms was observed when KSL was used in the presence of a surface-active agent, or after biofilms were mechanically disrupted. This study shows that KSL may be a useful adjunct for conventional oral hygiene to prevent plaque-mediated dental diseases.
