Abstract
Abstract Objective To establish a linear relationship between age and the development process of the mandibular second, third molars in a northern Chinese population and test its accuracy in inferring whether the subject is over 18 years old. Methods The orthopantograms (OPGs) of 960 northern Chinese people aged between 10.00 to 25.99 years were selected. The gender, birth date, and date of the orthopantograms of each sample were recorded. The development stages of left mandibular second and third molars were divided with Demirjian method. The experimental group (760 individuals) constructed a Logistic regression equation to infer whether the subject is over 18 years old. The validation group (200 individuals) tested the accuracy of the equation. Results When only using third molar, the formula obtained for inferring whether the subject's age is over 18 years is: logit P1=-18.276+0.494 x1+2.953 x3. When combining the second and the third molars, the formula is: logit P2=-21.045+3.177 x1+0.619 x2+2.088 x3. (x1 stands for gender, male is marked as 1 and female is marked as 2; x2 and x3 stand for the development stage of second molar and third molar, respectively). The accuracy rates of this equation in estimating whether ages of subjects from the validation group were over 18 years old for males and females were 88.0%-92.0% and 85.0%-88.0%, respectively. Conclusion The age estimation formulas based on the development of mandibular second and third molars have important value in judging whether the individual is over 18 years old. Meanwhile, the accuracy of age estimation can be improved by combining the development of second and third molars together.

Abstract
Iron-sulphur (Fe-S) clusters are versatile cofactors, which are essential for key metabolic processes in cells, such as respiration and photosynthesis, and which may have also played a crucial role in establishing life on Earth. They can be found in almost all living organisms, from unicellular prokaryotes and archaea to multicellular animals and plants, and exist in diverse forms. This review focuses on the most ancient Fe-S cluster assembly system, the sulphur utilization factor (SUF) mechanism, which is crucial in bacteria for cell survival under stress conditions such as oxidation and iron starvation, and which is also present in the chloroplasts of green microalgae and plants, where it is responsible for plastidial Fe-S protein maturation. We explain the SUF Fe-S cluster assembly process, the proteins involved, their regulation and provide evolutionary insights. We specifically focus on examples from Fe-S cluster synthesis in the model organisms Escherichia coli and Arabidopsis thaliana and discuss in an in vivo context the assembly of the [FeFe]-hydrogenase H-cluster from Chlamydomonas reinhardtii.

Abstract
Objective: To investigate the expression and prognosis effect of methylation-regulated SLIT3 and SPRCL1 genes in smoking-related lung adenocarcinoma. Methods: The expression levels of SLIT3 and SPARCL1 in cigarette smoke-induced malignant transformed cell (S30) and lung adenocarcinoma (LUAD) cell lines were measured by real-time fluorescence quantitative PCR (qPCR). Datasets of mRNA expression, DNA methylation and patient information data were obtained from The Cancer Genome Altas (TCGA) database. The mRNA expression levels of SLIT3 and SPARCL1 were validated in LUAD tissues. The 10-year survival curve of LUAD patients with different smoking history was plotted, and the correlation between mRNA expression level and DNA methylation level of LUAD patients was further analyzed. S30 cells were treated with 5-azacytidine (5-aza), an inhibitor of DNA methyltransferase, to analyze the methylation regulatory mechanism of SLIT3 and SPRCL1. Results: The qPCR results showed the significant down-regulation of SLIT3 and SPARCL1 in S30 cell and four LUAD cell lines (SLIT3: 0.493±0.134 and 0.041±0.014, 0.161±0.023, 0.277±0.055, 0.035±0.005; SPARCL1: 0.507±0.131 and 0.453±0.045, 0.420±0.040, 0.153±0.035, 0.430±0.050; all P<0.01). Bioinformatics analysis showed that SLIT3 and SPARCL1 were low expressed in LUAD tissue (8.12±1.58 vs 10.84±0.69 and 11.46±1.06 vs 13.57±0.67; both P<0.001) compared with adjacent peritumoral tissues, and expression levels of SLIT3 and SPARCL1 were significantly correlated with smoking history (both P<0.001). Non-smoker with high expression of SLIT3 and SPARCL1 was associated with better prognosis among LUAD patients. There was a significant negative correlation between promoter methylation and mRNA expression level of the two genes (r=-0.208, -0.574; both P<0.001). 5-aza treatment significantly up-regulated the expression levels of SLIT3 and SPARCL1 genes in S30 cells (2.137±0.281, 3.657±0.882; both P<0.01). Conclusion: SLIT3 and SPARCL1 can be regulated by DNA methylation and down-regulated in LUAD tissue, which has important prognostic significance on the smoking-induced LUAD patients.

Abstract
Objective: To explore the clinical classification of microcystic lymphatic malformations of tongue and observe the treatment of microcystic lymphatic malformations of tongue by retrospective analysis, in order to provide reference for clinical practice. Methods: From October 2005 to October 2015, the complete data of 220 cases of microcystic lymphatic malformations of tongue (115 males and 105 females) received and treated in Provincial Special Department of Vascular Anomalies, Linyi Tumor Hospital was analyzed retrospectively. The age ranged from 8 months to 52 years old, with a median age of 16 years old. All patients were followed up for 3 years, and according to their clinical manifestations, they were divided into three types: localized type of 23 cases, diffuse type of 161 cases, and megaloglossia type of 36 cases. Injection with pingyangmycin merely was performed on 58 cases, whereas merely surgery on 20 cases, injection with pingyangmycin combined with high frequency electrocoagulation on 55 cases, and surgery combined with injection with pingyangmycin on 87 cases. The therapeutic effect was evaluated according to the grade 4 standard. The χ(2) test was used for statistical analysis of count data. Rank sum test was used for statistical analysis of ranked data. Results: The percentage of surgery merely of localized type was 87.0% (20/23), significantly higher than that of other types of lesions [0% (0/197)] (χ(2)=178.060, P<0.001). The percentage of injection with pingyangmycin of diffuse type was 100% (161/161), significantly higher than that of other types of lesions [66.1% (39/59)] (χ(2)=60.034, P<0.001). The percentage of surgery combined with injection with pingyangmycin of megaloglossia type was 100% (36/36), significantly higher than that of other types of lesions [27.7% (51/184)] (χ(2)=65.800, P<0.001). After follow-ups for 3 to13 years, there were 0 cases of gradeⅠ, 11 cases of grade Ⅱ, 50 cases of grade Ⅲ, and 159 cases of grade Ⅳ. There were statistically significant differences in clinical efficacy among different clinical types (H=158.668, P<0.001). The percentage of level Ⅳ efficacy of localized type, diffuse type and megaloglossia type were 100% (23/23), 82.6% (133/161) and 8.3% (3/36) respectively. Local mucosa ulcer appeared in 45 cases and was cured through oral care and expectant treatment. Fever occurred in 28 cases and returned to normal within 24 h after expectant treatment. The lingual frenum was shortened in 16 cases. There were 12 cases with mild tongue swelling, 6 cases with influence on eating but without influence on breathing, and recovered spontaneously one week later. Conclusions: The choice of different treatment methods of microcystic lymphatic malformations of tongue should be made according their clinical classification. The only surgical resection is recommended for localized protrude lesions. Injection with pingyangmycin in high tension combined with surgical resection or high frequency electrocoagulation is effective for diffuse lesions. Surgical resection combined with injection with pingyangmycin is suitable for the patients with megaloglossia type.

Abstract
Objective:To synchronously perform external auricle examination during neonatal hearing screening, follow up auricle deformity with neonatal disease screening system, and calculate the incidence of auricle deformity, self-healing rate, correction rate, incidence of complications and the relationship with hearing loss in Zhuhai area. Method:According to the diagnostic criteria of auricle deformity, the newborns in Zhuhai Maternal and Child Health Hospital were examined on the spot within 2 months. The deformity auricle was registered and uploaded into the newborn hearing screening system. The newborns were followed up by short message notification 7 days after birth, and then compared with the photo uploading system again. At 14 days, the ears of those who could not self-heal were went on non-invasive correction, and collect of relevant data for summary analysis. Result:Among the 1 073 newborns(2 146 ears), 26(37 ears) with malformed ears were treated with auricular pattern correction.The corrective rates of newborns less than 14 days, 14-30 days and 31-60 days were 95%, 90% and 87% respectively, and the incidence of complications were 50%, 58% and 69%, respectively. Conclusion:The incidence of auricular deformities in neonates is high. The earlier correction the better. The ear deformity can be detected at the earliest stage and missed diagnosis can be avoided by simultaneous hearing screening and ear deformity screening. During the window period of 7-14 d, by monitoring the self-healing rate of the affected ear excessive medical correction can be avoided. By hearing screening system statistics, ear shape malformation is not directly related to hearing loss.

Abstract
Seasonal influenza vaccination is the most effective way to prevent influenza virus infection and its complications. Currently, China has licensed trivalent (IIV3) and quadrivalent inactivated influenza vaccine (IIV4), including split-virus influenza vaccine and subunit vaccine. In most parts of China, influenza vaccine is a category Ⅱ vaccine, which means influenza vaccination is voluntary, and recipients need to pay for it. To strengthen the technical guidance for prevention and control of influenza and the operational research on influenza vaccination in China, the National Immunization Advisory Committee (NIAC), Influenza Vaccine Technical Working Group (TWG), updated the 2014 technical guidelines and compiled the "Technical guidelines for seasonal influenza vaccination in China (2018-2019)" , based on most recent existing scientific evidences. The main updates include: epidemiology and disease burden of influenza, types of influenza vaccines, northern hemisphere influenza vaccination composition for the 2018-2019 season, and, IIV3 and IIV4 vaccines'major immune responses, durability of immunity, immunogenicity, vaccine efficacy, effectiveness, safety, cost-effectiveness and cost-benefit. The recommendations include: Points of Vaccination clinics (PoVs) should provide influenza vaccination to all persons aged 6 months and above who are willing to be vaccinated and do not have contraindications. No preferential recommendation is made for any influenza vaccine product for persons who can accept ≥1 licensed, recommended, and appropriate products. To decrease the risk of severe infections and complications due to influenza virus infection among high risk groups, the recommendations prioritize seasonal influenza vaccination for children aged 6-60 months, adults ≥60 years of age, persons with specific chronic diseases, healthcare workers, the family members and caregivers of infants <6 months of age, and pregnant women or women who plan to pregnant during the influenza season. Children aged 6 months to 8 years old require 2 doses of influenza vaccine administered a minimum of 4 weeks apart during their first season of vaccination for optimal protection. If they were vaccinated in previous influenza season, 1 dose is recommended. People ≥ 9 years old require 1 dose of influenza vaccine. It is recommended that people receive their influenza vaccination by the end of October. Influenza vaccination should be offered as soon as the vaccination is available. Influenza vaccination should continue to be available for those unable to be vaccinated before the end of October during the whole season. Influenza vaccine is also recommended for use in pregnant women during any trimester. These guidelines are intended for CDC members who are working on influenza control and prevention, PoVs members, healthcare workers from the departments of pediatrics, internal medicine, and infectious diseases, and members of maternity and child care institutions at all levels.

Abstract
Objective: To investigate the distribution and resistance of pathogens isolated from blood cultures in patients with hematological malignancies after chemotherapy in Union Hospital of Fujian Medical University so as to understand the real situation of blood stream infection (BSI) and provide the basis for rational use of antibiotics in clinic. Methods: The data of 657 strains isolated from blood culture specimens of patients with hematological malignancies from January 2013 to December 2016 were collected analyzed. Results: A total of 657 cases of blood culture positive bacterial strains were included in the study, involving 410 cases (62.4%) with single Gram-negative bacteria (G(-) bacteria) , 163 cases (24.8%) with single Gram-positive bacteria (G(+) bacteria) , 50 cases (7.6%) with single fungi. The most common 5 isolates in blood culture were Klebsiella pneumoniae (17.5%) , Escherichia coli (17.2%) , Coagulase negative staphylococci (CNS) (14.9%) , Pseudomonas aeruginosa (14.2%) and Staphylococcus aureus (3.5%) . The extended-spectrum beta-lactamase (ESBL) production rates of Klebsiella pneumoniae and Escherichia coli were 25.2% and 55.8%, respectively. ESBL producing strains were almost more resistant than non-ESBL producing strains. The resistance rates of Enterobacteriaceae to carbapenems, piperacillin/tazobactam and tigecycline were lower than 14.0%. The resistance rates of Pseudomonas aeruginosa to a variety of drugs were lower than 12.0%. Tigecycline-resistant Acinetobacter baumannii bacteria were not detected, and the resistance rates of Acinetobacter baumannii to cefixime and cefotaxime were 7.1%. Methicillin-resistant strains in CNS (MRCNS) and in Staphylococcus aureus (MRSA) accounted for 84.7% and 43.5%, respectively. Vancomycin, linezolid and tigecycline-resistant G(+) bacteria were not detected. Conclusion: The pathogens isolated from blood culture were widely distributed. Most of them were G(-) bacteria, and the resistance to antibiotics was quite common. Furhermore, vancomycin, linezolid and tigecycline can be chosen empirically to treat patiens who ar suspected to have G(+) bacterial BSI.

Abstract
Objective: To analyze and evaluate the effectiveness of individualized treatment regimen in the therapy of smear-positive retreatment pulmonary tuberculosis with mono-and poly-drug resistance, and therefor to provide information on how to develop rational individualized regimen for retreatment tuberculosis cases with drug resistance. Methods: This was a multi-centered, prospective cohort study. Totally 254 cases of sputum positive tuberculosis with previous treatment history during the period from July 1, 2009 to August 30, 2016 were included in the analysis. All the cases were randomly divided into 3 groups and received therapy after randomization into treatment groups. After 3 months, cases with multidrug resistant tuberculosis, extensively drug-resistant tuberculosis, non-tuberculosis mycobacterial infection and those with smear-positive but culture-negative tuberculosis were excluded according to result of sputum culture and drug susceptibility test (DST). In treatment group A (individualized treatment group), 86 cases with an average age of (42.1±13.7) years for men and (38.5±12.8) years for women, were treated with individualized regimen, which allowed drug replacement on the basis of standard regimen (2SHRZE/6HRE) according to DST result. Treatment duration was recalculated after drug replacement and the total length should be 12 months or more. If the DST result did not show drug resistance, the patients would continue the 8 months' standard treatment. In treatment group B (intensified retreatment regimen group), 86 cases with an average age of (43.2±14.2) years for man and (37.9±14.1) years for women, received intensified retreatment regimen (2HL(2)EZS/2HL(2)EZS(3)/4HL(2)E). The dose for H was 0.3 g/d for patients with body weight <50 kg, and 0.4~0.5 g/d for higher body weight (≥50 kg); The doses for L(2,)E and Z were 0.6 g, 2/w; 0.75, 1/d and 0.5g, 3/d. In treatment group C (standard treatment group), 82 cases with an average of (42.5±11.9) years for man and (38.6±12.8) years for women, were treated with standardized regimen recommended by national tuberculosis program (2HREZS/6HRE). In both group B and C, the total treatment duration was 8 months and the drugs were not replaced for mono-and poly-drug resistance. Treatment outcomes of the 3 groups were analyzed, the status of drug replacement in group A was analyzed, and the adjustment of dose of H and R according to patients' body weight was observed. SPSS 19.0 was used for data analysis. Results: The treatment cure rates for group A, B and C were 73.3%(63/86), 76.7%(66/86) and 50%(41/82), and the treatment success rates were 80.2%(69/86), 84.9%(73/86) and 62.2%(51/82) respectively. Treatment failure was 8.1%(7/86), 4.7%(4/86) and 19.5%(16/82) in 3 groups. There were significant differences in the above indicators for group A and B in comparison with group C(χ(2)=13.127, P=0.001). However, there was no difference observed between group A and B(χ(2)=0.646, P=0.422). In group A, tuberculosis specialized hospitals using regular doses for R was only 38.7%(12/31). After 3 years' follow-up, no-relapse-success for group A was 66.7% (10/15). Conclusions: Inappropriate individualized treatment would increase treatment failure for retreatment tuberculosis. Higher doses of H and R and prolonged extensive therapy phase could contribute to increased treatment success.

Abstract
Acceptor-sensitised 3-cube fluorescence resonance energy transfer (FRET) imaging (also termed as E-FRET imaging) is a popular fluorescence intensity-based FRET quantification method. Here, an automated E-FRET microscope with user-friendly interfaces was set up for dynamical online quantitative live-cell FRET imaging. This microscope reduces the time of a quantitative E-FRET imaging from 12 to 3 s. After locating cells, calibration of the microscope and E-FRET imaging of the cells can be performed automatically by clicking 'Capture' button on interfaces. E-FRET imaging was performed on the microscope for living cells expressing different FRET tandem constructs. Dynamical E-FRET imaging on the microscope for live cells coexpressing CFP-Bax and YFP-Bax treated by staurosporine (STS) revealed three Bax redistribution stages: Bax translocation from cytosol to mitochondria within 10 min, membrane insertion with conformational change on mitochondrial membrane within about 30 min, and subsequent oligomerisation within about 10 min. Because of excellent user-friendly interface and stability, the automated E-FRET microscope is a convenient tool for quantitative FRET imaging of living cell. LAY DESCRIPTION: Acceptor-sensitised 3-cube fluorescence resonance energy transfer (FRET) imaging (also termed as E-FRET) is a popular fluorescence intensity-based FRET quantification methods. E-FRET measurements are currently performed manually, and a complete FRET measurement takes about 12 s. E-FRET measurement necessitates not only a skilled operator and specialised equipment but also expertise in the interpretation of FRET signals, a considerable challenge in the application of FRET technology in living cells. Furthermore, manual E-FRET microscope is hard to perform dynamical quantitative FRET measurement, the ever-increasing applications in mapping the biochemical signal transduction within cells. Here, an automated E-FRET microscope with user-friendly interfaces was set up for dynamical online quantitative live-cell FRET imaging. This microscope reduces the time of a quantitative E-FRET imaging from 12 to 3 s. After locating cells, calibration of the microscope and E-FRET imaging of the cells can be performed automatically by clicking 'Capture' button on interfaces. Because of excellent user-friendly interface and stability, the automated E-FRET microscope is a convenient tool for quantitative FRET imaging of living cell.

Abstract
PURPOSE The prognostic value of nonsentinel lymph-node (NSLN) status in breast cancer remains unclear. This study was designed to investigate the prognostic value of NSLN status in SLN-positive breast cancer. METHODS Retrospective 873 consecutive primary breast cancer patients from a single institution who were SLN-positive and underwent axillary lymph-node dissection (ALND) were included. Patients with incomplete clinical information or loss of follow-up were excluded. Survival analysis in patients with the same number of positive LNs and patients belonging to the same American Joint Committee on Cancer (AJCC) node (N) classification was performed to establish a proposal for incorporating the NSLN status into the breast cancer staging system. RESULTS The median follow-up was 41 months. Positive NSLN status was a significantly unfavorable factor for recurrence-free survival (RFS) (HR: 4.31, P < 0.001) and distant recurrence-free survival (DRFS) (HR: 3.62, P < 0.001). The survival of patients with one positive SLN and one positive NSLN (N = 97) was significantly worse than that of patients with two positive SLNs (N = 68; RFS, P = 0.011; DRFS, P = 0.027). Positive NSLN status was a significantly unfavorable factor affecting survival in patients with the AJCC N1 classification (N = 806; RFS, HR: 2.85, P = 0.002; DRFS, HR: 2.81, P = 0.004). No significant difference in survival was found between LN-negative (N = 361) and NSLN-negative AJCC N1 classification (N = 363) patients. CONCLUSIONS Positive NSLN status has an independent prognostic value in breast cancer patients with 1-3 positive LNs, and the NSLN status should be incorporated into the breast cancer staging system.

OBJECTIVE To examine the association between physical frailty and risk of needing long-term care, and compare the predictive value and clinical usefulness of a simple frailty scale (FRAIL) with that of the original Cardiovascular Health Study (CHS) criteria. DESIGN AND SETTING A 6-year prospective cohort study of community-dwelling older adults in a west Japanese suburban town. PARTICIPANTS 1,554 older adults aged 65 years and over who were initially free of long-term care needs at baseline. MEASUREMENTS Physical frailty was defined by the CHS criteria and the FRAIL scale. The onset of needing long-term care was ascertained using national records of certification of long-term care needs. Cox proportional hazard models were used to estimate the association between physical frailty and risk of needing long-term care. Decision curve analysis was performed to compare the clinical usefulness of the two physical frailty criteria. RESULTS During a median follow-up of 5.8 years, 244 were ascertained as needing long-term care. Baseline physical frailty was significantly associated with elevated risk of needing long-term care, with a multivariable-adjusted hazard ratio (HR) of 2.00 (95% confidence interval [CI], 1.32-3.02) for being frail and 1.50 (95% CI, 1.10-2.03) for being pre-frail as defined by the CHS criteria, compared with being robust (p for trend = 0.001). Similar results were found for physical frailty defined by the FRAIL scale, with a multivariable-adjusted HR (95% CIs) of 2.11 (1.25-3.56) for being frail and 1.73 (1.28-2.35) for being pre-frail vs. being robust (p for trend < 0.001). The two physical frailty criteria had similar net benefits in identifying individuals at high risk for needing long-term care. CONCLUSIONS Physical frailty is significantly associated with an increased risk of needing long-term care in community-dwelling older adults in Japan. Compared with the original CHS criteria, the simple FRAIL scale has comparable predictive value and clinical usefulness for identifying individuals at risk for needing long-term care.

Abstract
Mitochondria play a critical role in oocyte developmental competence by providing energy to the oocyte through oxidative phosphorylation. We hypothesised that oxygen consumption, a measure of mitochondrial function, would be lower in the oocytes of old versus young mares as a potential mechanism of reduced developmental competence associated with equine aging. To test this hypothesis, we used a novel electrochemical sensor device to compare basal and maximal oxygen consumption rates of oocytes obtained from mares aged 6 to 12 years (Young, n=8 from 7 mares) and=20 years (Old, n=12 from 8 mares). Cumulus-oocyte complexes (COC) were collected by transvaginal, ultrasound-guided follicular aspirations of dominant follicles (35mm) during oestrus and at 16±2h after induction of follicular maturation (2000IU of hCG and 0.75mg of deslorelin acetate). Recovered COC were incubated in medium [TCM-199; Life Technologies, Grand Island, NY, USA) with 10% fetal calf serum, 25mg mL−1 gentamicin, and 0.2mM pyruvate] at 38.5°C in 5% CO2 and air for 26±2h. After maturation, COC were stripped of cumulus cells and checked for the presence of an extruded polar body before electrochemical measurements using amperometry. A microchamber with a 3-electrode system (working, counter, and reference electrodes) was filled with 120µL of medium (G-MOPS™, Vitrolife, Englewood, CO, USA) and overlaid with 120µL of paraffin oil (OVOIL™, Vitrolife). The baseline current was measured before adding the oocyte through the oil layer and over the centre of the working electrode. Oxygen consumption was monitored as the linear decrease in the oxygen reduction current over time, which was converted to femtomoles of O2 consumed per second (fmol s−1) using a calibration curve for the sensor. Basal (nonstimulated) oxygen consumption was measured for 5min, followed by assessment of maximal noncoupled respiratory capacity obtained by titrating 1 µM carbonyl cyanide m-chlorophenyl hydrazone (CCCP) at 8-min intervals. The highest value observed during CCCP titrations was considered the maximal oxygen consumption. Two-tailed Student’s t-tests were used to analyse data. Oocytes from young mares had higher basal oxygen consumption compared with old mares, respectively (mean±s.e.m., 1.74±0.18 and 1.27±0.09 fmol s−1; P=0.04) as well as higher maximal oxygen consumption (2.67±0.19 and 2.05±0.12 fmol s−1; P=0.016). Mitochondrial efficiency (maximal/basal oxygen consumption) was not different for Young and Old, respectively (1.62±0.13 and 1.65±0.07; P=0.9). In summary, we used a novel electrochemical sensor device to measure basal and maximal oxygen consumption of oocytes and to confirm our hypothesis that aging impairs mitochondrial respiratory capacity in equine oocytes, which may contribute to age-associated changes in equine fertility.

Abstract
Objective: Application of technique of high resolution CT (HRCT) and multipliate plane reconstruction, analyzed the image features of suspicious superior semicircular canal dehiscence (SSCD) to improve the understanding of the SSCD.Method:From January 2016 to April 2017, a total of 230 adult patients who checked temporal bone HRCT were collected in this retrospective study, of which 160 cases (320 ears) of the non-SSCD, 73 cases were male (146 ears), 87 cases were female (174 ears), aged 18 to 70 years old; 70 cases (113 ears) were suspicious diagnosed with SSCD, 33 cases were male (55 ears), 37 cases were female (58 ears), and 18 to 71 years old. The thin section CT scan of the temporal bone translocation was performed on all subjects, then the CT post processing workstation was used for multipliate plane reconstruction (MPR), and the main rows of coronal and oblique sagittal image reconstruction was performed. To observe, measure and record the HRCT features and datas of the suspicious SSCD and non-SSCD, then analyze the collected data.Result:There were 160 cases (320 ears) in non-SSCD group, and the height of the superior semicircular canal was (6.43±0.51)mm, the outer tube diameter was (0.83±0.13)mm, the thickness of the tympanic cavity was (2.19±0.62)mm, the anteroposterior diameter of mastoid was (14.55±1.98)mm; There were 70 cases (113 ears) in the suspicious SSCD group, the above results were (6.42±0.60)mm, (0.85±0.16)mm, (1.62±0.55)mm, (13.24±1.97)mm, respectively. Statistical analysis showed that there were no significant difference in the height of the superior semicircular canal (P=0.94) and the outer tube diameter (P=0.64), There were significant differences in the thickness of the tympanic cavity (P=0.002) and the anteroposterior diameter of mastoid (P=0.004). There were 70 cases (113 ears) in group suspicious SSCD, the unilateral defect had 27 cases (27 ears), and bilateral defect had 43 cases (86 ears). The defect was located in the middle of the parietal wall in 48 ears, located in the anterior wall of 20 ears, located in the posterior wall of 32 ears, more than two defects in 13 ears; 7 ears were mastoid pneumatic type, 90 ears were mastoid sclerotic type, 16 ears were mastoid mixed type.Conclusion:The SSCD was more common in the sclerotic mastoid. The bilateral defect was common, mostly located in the middle of the parietal wall. The occurrence of the lesion is not related to the height and diameter of the superior semicircular canal, but may be related to the thinning of the whole temporal bone.

Abstract
AIM To determine whether dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) quantitative parameters increase the detectability of MRI-invisible residual cervical cancer after conisation. MATERIALS AND METHODS This retrospective study included 59 patients with MRI-invisible cervical cancer, but positive conisation pathology. Thirty-five patients were confirmed to have residual cervical cancer, and 24 patients showed non-residual cervical cancer. DCE-MRI quantitative parameters were calculated in the anterior or posterior cervix according to the conisation position. Receiver operating characteristic (ROC) analysis was used to find the threshold of DCE-MRI parameters in differentiate residual cervical cancer patients from non-residual cervical cancer patients after conisation. RESULTS For patients with residual cervical cancer, the Ktrans and Ve values were significantly higher than in their counterparts with non-residual cervical cancer (0.610±0.395 versus 0.366±0.305/min, p=0.013; and 0.703±0.270 versus 0.540±0.280%, p=0.028; respectively). The Ktrans showed the highest area under the ROC curve (AUC) of 0.705 (p=0.004) with a sensitivity of 67.6% and specificity of 68%. CONCLUSION DCE-MRI quantitative parameters increased the detectability of MRI-invisible residual cervical cancer after conisation.

Abstract
HBV surface antigen (HBsAg) reduction is well observed in chronic hepatitis B (CHB) patients treated with pegylated interferon alpha-2a (PegIFNα). However, the mechanism of HBsAg suppression has not been fully elucidated. Twenty-seven of 55 entecavir-treated CHB e antigen positive patients were switched to PegIFNα treatment (Group A) whereas 28 patients continued entecavir treatment (Group B). The percentage or absolute number of CD56bright /CD56dim NK cells, expression of receptors and cytokines were evaluated by flow cytometry for 48 weeks and correlated with treatment efficacy. In vitro, purified NK cells were co-cultured with HepAD38 cells for measurement of HBsAg, apoptosis and covalently closed circular DNA (cccDNA). In association with a reduction of HBsAg, the percentage and absolute number of CD56bright NK cells was significantly elevated in patients in group A, especially in Virologic Responders (VRs, HBsAg decreased). Furthermore, the percentage of NKp30+ , NKp46+ , TRAIL+ , TNF-α+ and IFNγ+ CD56bright NK cells were significantly expanded in Group A, which were positively correlated with the decline of HBsAg at week 48. In vitro, peripheral NK cells from Group A induced a decline of HBsAg in comparison with NK cells from Group B which was significantly inhibited by anti-TRAIL, anti-TNF-α and anti-IFNγ antibodies. Furthermore, apoptosis of HepAD38 cells and levels of cccDNA, were significantly reduced by TRAIL+ and TNF-α+ /IFNγ+ NK cells from Group A, respectively. A functional restoration of CD56bright NK cells in entecavir-treated patients who were switched to PegIFNα contributes to HBsAg and cccDNA clearance through TRAIL-induced cytolysis and TNF-α/IFNγ-mediated noncytolytic pathways.

Abstract
A virulent infectious bronchitis virus (IBV), designated as CK/CH/GD/QY16 (referred as QY16), was isolated from a diseased chicken farm in Guangdong province, China, in 2016. The complete genome of the strain was sequenced and analyzed. The results show that the genome of QY16 consists of 27,670 nucleotides, excluding poly (A) tail, and that its genome organization is 5’ UTR-1a-1b-S-3a-3b-E-M-4b-4c-5a-5b-N-6b-3’ UTR-poly (A) tail. Sequence comparison among QY16 and other IBV strains was conducted and its results demonstrate that the S1 gene of QY16 has the highest nucleotide sequence identity with that of 4/91, and the other part of its genome is highly similar to that of YX10. The results of the phylogenic analysis show that the entire genome of QY16 and most of the QY16 genes are located in the same cluster as those of YX10, except for the S1 gene which is located in the same cluster with that of 4/91. It has been further confirmed by the RDP and SimPlot analysis that QY16 is a recombinant strain deriving from YX10 (as the major parental sequence) and 4/91 (as the minor parental sequence), and that the recombination occurs in a region which includes the 3’-terminal 1b sequence (85 nt) and the 5’-terminal S1 protein gene sequence (1,466 nt). The results of the vaccination-challenge test suggest that QY16 is a nephropathogenic strain of IBV and that the vaccine strains–H120 and 4/91—cannot provide effective protection against it. These results indicate that the continuing evolution of IBV strains by genetic drift and genetic recombination may lead to IBV outbreaks even among the vaccinated chickens in China.

Abstract
The cause of changes in atmospheric carbon dioxide (CO2) during the recent ice ages is yet to be fully explained. Most mechanisms for glacial-interglacial CO2 change have centred on carbon exchange with the deep ocean, owing to its large size and relatively rapid exchange with the atmosphere1. The Southern Ocean is thought to have a key role in this exchange, as much of the deep ocean is ventilated to the atmosphere in this region2. However, it is difficult to reconstruct changes in deep Southern Ocean carbon storage, so few direct tests of this hypothesis have been carried out. Here we present deep-sea coral boron isotope data that track the pH-and thus the CO2 chemistry-of the deep Southern Ocean over the past forty thousand years. At sites closest to the Antarctic continental margin, and most influenced by the deep southern waters that form the ocean's lower overturning cell, we find a close relationship between ocean pH and atmospheric CO2: during intervals of low CO2, ocean pH is low, reflecting enhanced ocean carbon storage; and during intervals of rising CO2, ocean pH rises, reflecting loss of carbon from the ocean to the atmosphere. Correspondingly, at shallower sites we find rapid (millennial- to centennial-scale) decreases in pH during abrupt increases in CO2, reflecting the rapid transfer of carbon from the deep ocean to the upper ocean and atmosphere. Our findings confirm the importance of the deep Southern Ocean in ice-age CO2 change, and show that deep-ocean CO2 release can occur as a dynamic feedback to rapid climate change on centennial timescales.

Abstract
Objective: To investigate the effect of mediastinal lymph node resection, metastasis status and treatment on the prognosis of patients with stage Ⅲ-pN2 non-small cell lung cancer (NSCLC). Methods: Clinical data of 206 patients who were pathologically diagnosed as stage Ⅲ-pN2 NSCLC in Tongji Hospital from July 2006 to Dec 2009 were retrospectively analyzed and followed up. Log rank test and Cox proportional hazards regression model were used to analyze the prognostic significance of mediastinal lymph node excision, metastasis state and treatment. Results: The median overall survival (OS) time of the whole group was 29.6 months, and the median disease-free survival (DFS) time was 27.2 months. Univariate analysis showed that the less number of mediastinal lymph node stations with metastasis (single station), the less number of mediastinal lymph nodes involved (less than 2), and postoperative chemotherapy were associated with longer postoperative OS and DFS time (P<0.05 for all). The patients with skip metastasis, negative metastasis of subcarinal lymph node, the lower mediastinal lymph node metastasis rate (MLNR<33%) and postoperative radiotherapy had longer OS and DFS time than those without these factors (P<0.05 for all). Multivariate analysis showed that metastasis of subcarinal lymph node, MLNR and postoperative chemotherapy were the independent prognostic factors for patients with stage Ⅲ-pN2 NSCLC (P<0.05 for all). Conclusion: Metastasis of subcarinal lymph nodes and the higher MLNR might shorten the postoperative survival time of NSCLC patients with stage Ⅲ-pN2, whereas postoperative chemotherapy prolongs the survival time.

Abstract
The amyloid hypothesis has been the dominant framework for Alzheimer's disease (AD) research, including the development of anti-AD therapies. However, none of the phase III clinical trials conducted to date that targeted amyloid β (Aβ) production, aggregation, or clearance demonstrated a statistically significant treatment effect in patients with AD. This includes the approach of using monoclonal antibodies that recognize various Aβ epitopes and display different binding selectivity. While some monoclonal antibodies have failed in phase III trials, several are still in development. Aducanumab (BIIB037) is a human antibody that selectively targets aggregated forms of Aβ, including soluble oligomers and insoluble fibrils. In PRIME (NCT01677572), an ongoing phase Ib trial (N=196 patients dosed), aducanumab was shown to reduce Aβ plaques and slow decline in clinical measures in patients with prodromal or mild AD, with acceptable safety and tolerability. The main safety finding was amyloid-related imaging abnormalities (ARIA), a side effect associated with removal of Aβ, which was dose-dependent and occurred more often in ApoE ε4 carriers than non-carriers. ENGAGE (NCT02477800) and EMERGE (NCT02484547), the ongoing phase III trials of aducanumab in early AD, have been designed based on the outcomes of PRIME and on lessons from past clinical trials in patients with AD. Those study design features include patient selection with confirmed Aβ pathology, ensuring sufficient target engagement, and conducting clinical trials in patients at earlier symptomatic stages of AD.

Abstract
Objective: This study was designed to identify the relative factors, bacteriological profile and their antibiotic susceptibility pattern of neonatal sepsis. Methods: A retrospective survey was conducted on the clinical information, pathogen identification and antibiotic sensitivity results of 425 newborns with neonatal sepsis admitted to Nanjing Maternity and Child Health Care Hospital from 2010 to 2017. Of the 425 positive blood-cultures, 148 (34.82%) were early-onset neonatal sepsis (EOS) and 277 (65.18%) were late-onset neonatal sepsis (LOS). Clinical information and pathogen identification were compared between EOS and LOS. Antibiotic sensitivity of gram negative organisms (G(-)) and gram positive organisms (G(+)) were also detected. Results: The rates of premature delivery (78.70%, n=218), low birth weights (67.15%, n=186) and cesarean delivery (59.57%, n=165) were significantly increased in LOS (P<0.05) compared with those rates in EOS, which were 41.89% (n=62), 37.84% (n=56) and 46.62% (n=69). Parturients fever (18.24%, n=27) and meconium like amniotic fluid (25.68%, n=38) were significantly increased in EOS (P<0.05) compared with those rates in LOS, which were 7.94% (n=22) and 5.42% (n=15). Among the identified pathogen, the incidence of G(-) and G(+) bacteria were 216 (50.83%) and 201 (47.29%) respectively, and the rest was Candida glabrata (1.88%, n=8). Escherichia coli 68 (16.00%) was the predominant isolate followed by Klebsiella pneumoniae (13.18%, n=56). The detection rate of Hemolytic staphylococcus (10.81%, n=16) was significantly increased in EOS (P<0.001) compared with LOS (1.44%, n=4). However, the incidence of Klebsiella pneumonia (5.88%, n=44) was higher in LOS (P=0.024) compared with EOS (8.11%, n=12). Most of the gram positive isolates exhibited high resistance to penicillin (90.32%-100.00%) and cephalosporin group antibiotics (25.00%-100.00%). Similarly, the majority of the gram negative isolates showed higher resistance to ampicillin (83.33%-100.00%), but susceptible to aminoglycosides (0-11.76%), quinolones (0-17.65%) and β-lactams (0-5.88%). Conclusion: Among the study population, the percent of preterm, low birth weight and cesarean section were higher in LOS while parturients fever and meconium-like amniotic fluid were higher in EOS. The pathogens with the highest detection rate were Escherichia coli and Klebsiella pneumoniae. The results of antibiotic susceptibility test showed that common pathogens had high resistance to commonly used antibacterial drugs.

Abstract
BACKGROUND Huaier extract has been demonstrated to exhibit potent anti-tumor effects in various types of cancer cells. However, the clinical benefit of Huaier granule in breast cancer has not been reported. In this study, we aimed to evaluate the efficacy of Huaier granule in breast cancer patients. METHODS Our study included 284 breast cancer patients treated with or without Huaier granule between January 2005 and October 2016 at Qilu Hospital, Shandong University, Jinan, China. Retrospective data obtained included demographics, clinicopathological characteristics, disease-free survival (DFS), serum concentrations of tumor markers, the Karnofsky performance scale (KPS), and incidences of emotional symptoms. DFS was the main outcome measure. RESULTS Of the patients included, 144 were classified into the control group and 140 into the Huaier group. Baseline characteristics were well balanced between the study arms. Median DFS was 91.43 months for control group and 112.61 months for Huaier group (hazard ratio (HR) = 2.97, 95% confidence interval (CI) = 1.57-5.61, p < 0.01). After Huaier granule treatment, the serum levels of tumor markers could be reduced to the normal range. In addition, breast cancer patients with Huaier granule treatment had higher KPS scores and less emotional symptoms. CONCLUSIONS Our data demonstrated that patients orally administrated Huaier granule got longer DFS. Furthermore, Huaier granule could reduce serum tumor markers, improve the functional status, and decrease the incidences of emotional symptoms in breast cancer patients. Therefore, Huaier granule was an effective therapy for women with breast cancer.

Abstract
Objective: To analyze the reasons for the fluctuations in the percentage of outpatient or emergency visits for influenza-like illness (ILI) during the Spring Festival and National Day in 2014-2018 surveillance season. Methods: ILI surveillance data was collected during the period of Spring Festival and National Day in mainland China, and downloaded from Chinese Influenza Surveillance Information System, during the 2014-2018 surveillance season. Results: There was no significant difference noticed in the number of ILI reports in the festival week with weeks before or after in both the southern and northern provinces. The number of outpatient visits was much less than that of the week before and after, but the number of emergency visits was statistically significantly increased. Conclusion: In the holiday peak of ILI%, the major causes was the impact of holiday-off at sentinel hospitals, resulting in a large reduction in the number of outpatient visits in the consulting room during the festivals.

Abstract
Decabromodiphenyl ethane (DBDPE) is a kind of new brominated flame retardants, which is widely used as a replace of decabromodiphenyl ether in electronic appliances, textiles and other goods. This review summarizes environmental levels and body burden of human beings of DBDPE in recent years. The data shows that the concentration of DBDPE in the environment and human tissues shows an upward trend. According to limited experiments about its toxicity, DBDPE shows similar toxicity to decabromodiphenyl ether. DBDPE can interfere thyroid hormones balance, and cause damage to liver, reproductive development, kidney, et al, which implies that DBDPE might be another new persistent organic pollutant. Further researches are needed.

Abstract
An effective resistivity relevant to collisionless magnetic reconnection (MR) in plasma is presented. It is based on the argument that pitch angle scattering of electrons in the small electron diffusion region around the X line can lead to an effective, resistivity in collisionless plasma. The effective resistivity so obtained is in the form of a power law of the local plasma and magnetic field parameters. Its validity is confirmed by direct collisionless particle-in-cell (PIC) simulation. The result agrees very well with the resistivity (obtained from available data) of a large number of environments susceptible to MR: from the intergalactic and interstellar to solar and terrestrial to laboratory fusion plasmas. The scaling law can readily be incorporated into existing collisional magnetohydrodynamic simulation codes to investigate collisionless MR, as well as serve as a guide to ab initio theoretical investigations of the collisionless MR process.

Abstract
The VicRK 2-component system of Streptococcus mutans regulates genes associated with cell wall biogenesis and biofilm formation. A putative RNase III-encoding gene ( rnc) is located downstream from the vicRKX operon. The goals of this study were to investigate the potential role of VicR in the regulation of adjacent downstream genes and evaluate transcription levels of vicR during planktonic and biofilm growth. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to investigate whether vicRKX and adjacent downstream genes were cotranscribed. Binding of purified recombinant VicR protein to promoter regions of vicR, rnc, and syfA genes was confirmed by electrophoretic mobility shift assay and by chromatin immunoprecipitation analyses. VicR antisense (AS vicR) RNA was detected by Northern blotting and qRT-PCR assays. AS vicR overexpression mutants were constructed, and the biofilm biomass was determined by crystal violet microtiter assay. Adjacent downstream genes rnc, smc, syfA, smu.1511, and syfB were cotranscribed with vicRKX. The predicted promoter regions of vicR, rnc, and syfA genes were directly regulated by VicR. An AS vicR RNA transcript was detected upstream of the rnc gene. Expression of the AS vicR RNA transcript was elevated in planktonic cultures and repressed during biofilm growth. In addition, Western blot data showed that expression of the VicR protein decreased by 35% in planktonic as compared with biofilm cultures. Furthermore, we show that overexpression of AS vicR led to a reduction in biofilm formation. The downstream genes rnc, smc, syfA, smu.1511, and syfB are cotranscribed with vicRKX. VicR is autophosphorylated, and rnc and syfA are directly regulated by VicR. Expression of VicR protein correlated inversely with different levels of AS vicR RNA transcript and growth conditions. The biofilm biomass decreased in the AS vicR overexpression mutant. These data suggest a role for the AS vicR RNA transcript in posttranscriptional regulation of VicR protein production in S. mutans.
