Abstract
Field transformation is complementary to transformation optics as it converts polarization without reflection for any incidence, despite not being impedance-matched to vacuum. However, to ease manufacture, a dielectric approximation may degrade the transmission performance due to the approximate dispersion relation for the exact reciprocal medium. In this paper, we instead propose a different dielectric equivalent medium to guarantee the exact dispersion. We also discuss the birefringence phenomenon in such dielectric media, and their unavoidable induced reflections.

Abstract
Background:Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). A recent ad hoc safety analysis (as of August 2019; may be subject to change) from an ongoing, open-label, randomised, post-authorisation safety study, Study A3921133 (NCT02092467), conducted in RA patients (pts) aged ≥50 years with ≥1 cardiovascular risk factor has shown that incidence rates (IRs) of serious infection events (SIEs) were higher with tofacitinib 10 mg BID vs tumour necrosis factor inhibitors (TNFi; adalimumab [ADA] and etanercept) and this difference was more pronounced in pts aged ≥65 years (Pfizer Inc; data on file).Objectives:To assess the IRs of overall infection events and SIEs in pts from Phase (P)2, P3 and P3b/4 tofacitinib RA trials which had a TNFi (ADA) active control or comparator arm.Methods:This is a post hoc analysis of Month 0–12 data pooled from P2 (A3921035;NCT00550446[first 12-week randomised parallel treatment period only]), P3 (ORAL Standard;NCT00853385) and P3b/4 (ORAL Strategy;NCT02187055) studies. Pts randomised to receive tofacitinib 5 mg BID, tofacitinib 10 mg BID, ADA 40 mg subcutaneously every other week and placebo (PBO) were included and assessed overall and by age (<65 or ≥65 years). SIEs were defined as infections requiring hospitalisation or parenteral antimicrobial therapy, or meeting other criteria for a serious adverse event. IRs (pts with events/100 pt-years of exposure [PY]) and 95% confidence intervals (CIs) were calculated for all infection events and SIEs; only the first infection events that occurred up to 28 days after the last dose or to the data cut-off date were considered.Results:Of 2180 pts included in the pooled studies (tofacitinib 5 mg BID: N=1064 [943.4 PY]; tofacitinib 10 mg BID: N=306 [236.6 PY]; ADA: N=643 [554.3 PY]; PBO: N=167 [108.1 PY]), 1841 (84.4%) were aged <65 years and 339 (15.6%) were aged ≥65 years. In general, the IRs for all infection events and SIEs were higher with tofacitinib 5 mg BID, tofacitinib 10 mg BID and ADA in pts aged ≥65 years compared with pts aged <65 years. Overall and when stratified by age, IRs for all infection events were similar across the active treatment groups (Figure 1); IRs with PBO were lower vs the active treatment groups overall and in pts aged <65 years, and numerically lower vs the active treatment groups in pts aged ≥65 years. IRs for SIEs were comparable across active treatment groups in pts aged <65 years, while among pts aged ≥65 years, IRs were numerically higher for tofacitinib 10 mg BID vs ADA, and appeared to be similar for tofacitinib 5 mg BID and ADA (Figure 2).Conclusion:In this analysis of data pooled from P2, P3 and P3b/4 tofacitinib RA studies which included a TNFi arm (ADA), the risk of SIEs or infections overall was similar for tofacitinib and ADA with the exception of a numerically higher rate of SIEs with tofacitinib 10 mg BID vs ADA in pts aged ≥65 years. In most countries, tofacitinib 10 mg BID is not an approved dose for the treatment of RA. This post hoc comparison is limited by variation in sample size and PY of exposure between treatment and age groups, and a small number of cases of SIEs in the ≥65-year age group resulting in wide 95% CIs; interpretation of results should be made with caution. The findings in the present analysis are consistent with increasing age being a known risk factor for infections.Acknowledgments:Study sponsored by Pfizer Inc.

Abstract
OBJECTIVE To evaluate the performance of an ultrafast single-tube nucleic acid isothermal amplification detection assay for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA using clinical samples from multiple centres. METHODS A reverse transcription recombinase-aided amplification (RT-RAA) assay for SARS-CoV-2 was conducted within 15 minutes at 39°C with portable instruments after addition of extracted RNA. The clinical performance of RT-RAA assay was evaluated using 947 clinical samples from five institutions in four regions of China; approved commercial fluorescence quantitative real-time PCR (qRT-PCR) kits were used for parallel detection. The sensitivity and specificity of RT-RAA were compared and analysed. RESULTS The RT-RAA test results of 926 samples were consistent with those of qRT-PCR (330 were positive, 596 negative); 21 results were inconsistent. The sensitivity and specificity of RT-RAA was 97.63% (330/338, 95% confidence interval (CI) 95.21 to 98.90) and 97.87% (596/609, 95% CI 96.28 to 98.81) respectively. The positive and negative predictive values were 96.21% (330/343, 95% CI 93.45 to 97.88) and 98.68% (596/604, 95% CI 97.30 to 99.38) respectively. The total coincidence rate was 97.78% (926/947, 95% CI 96.80 to 98.70), and the kappa was 0.952 (p < 0.05). CONCLUSIONS With comparable sensitivity and specificity to the commercial qRT-PCR kits, RT-RAA assay for SARS-CoV-2 exhibited the distinctive advantages of simplicity and rapidity in terms of operation and turnaround time.

Abstract
Insufficient acidification results in dark, firm, and dry beef. While this defect is often indicative of a stress event antemortem, muscle tissue may change in response to feeding regime. Longissimus dorsi muscle samples from 10 grain-fed and 10 grass-fed market weight, angus-crossbred beef cattle were collected postmortem. Lower (P < .05) L* and a* values were recorded for steaks from grass-fed cattle. Higher (P < .05) ultimate pH values were noted in lean of grass-fed cattle compared to grain-fed cattle, yet differences in lactate, glycogen and glucose were not detected. Further, increased (P < .05) ultimate pH values and lower (P < .05) lactate accumulations were noted when samples from grass-fed cattle were subjected to an in vitro glycolysis system. Muscle from grass-fed beef possessed nearly two-fold more (P < .05) succinate dehydrogenase and (P < .001) myoglobin than that of grain-fed cattle. These data show lean from grass-fed beef has greater enzymes reflective of oxidative metabolism and suggest dark lean from grass-fed cattle may be a function of more oxidative metabolism rather than a stress-related event antemortem.

Abstract
Mucosal-associated invariant T (MAIT) cells in HIV-1-infected individuals are functionally impaired by poorly understood mechanisms. Single-cell transcriptional and surface protein analyses revealed that peripheral MAIT cells from HIV-1-infected subjects were highly activated with the up-regulation of interferon (IFN)-stimulated genes as compared to healthy individuals. Sustained IFN-α treatment suppressed MAIT cell responses to Escherichia coli by triggering high-level interleukin-10 (IL-10) production by monocytes, which subsequently inhibited the secretion of IL-12, a crucial costimulatory cytokine for MAIT cell activation. Blocking IFN-α or IL-10 receptors prevented MAIT cell dysfunction induced by HIV-1 exposure in vitro. Moreover, blocking the IL-10 receptor significantly improved anti-Mycobacterium tuberculosis responses of MAIT cells from HIV-1-infected patients. Our findings demonstrate the central role of the IFN-I/IL-10 axis in MAIT cell dysfunction during HIV-1 infection, which has implications for the development of anti-IFN-I/IL-10 strategies against bacterial coinfections in HIV-1-infected patients.

Abstract
Context
Currently, the commonly used dietary calcium sources are not sufficiently bioavailable to be used for eggshell formation or bone health in laying hens. Protected calcium, a blend of calcium and medium-chain fatty acids with matrix coating, may exert an effective absorption and metabolism ability for calcium consumption in the laying hen.
Aims
The present study was conducted to evaluate the effects of protected-calcium supplementation on egg production, egg quality, and serum calcium and phosphorus concentrations in laying hens.
Methods
In total, 144 Hy-line brown laying hens (25 weeks old) were randomly allotted to three treatments (8 replicates with 6 hens, 1 hen per cage) in a 10-week trial. Treatments consisted of corn–wheat–soybean meal-based basal diet with limestone (coarse limestone:fine limestone = 50:50) as a calcium source (CON) or basal diet supplemented with 0.5% (P1) or 1% (P2) protected calcium in substitution for an equal quantity of coarse limestone. Data were statistically analysed using linear and quadratic contrast with the GLM procedure of SAS. Probability values of <0.05 indicate significance.
Key results
At Weeks 31–33 and 35, the cracked-egg rates were lower in the P1 and P2 groups than in the CON group (P < 0.05; linear, P < 0.05) and, at Weeks 29 and 34, the cracked-egg rates in the P2 group were also significantly (P < 0.05) decreased. At Weeks 26, 30 and 32, the Haugh units in the P2 group were significantly (P < 0.05) higher than those in the CON group. In addition, eggshell strength was increased significantly (P < 0.05) in the P2 group at Weeks 26, 27 and 31–35. The serum calcium concentration of the P2 group was significantly (P < 0.05) greater than that of the CON group in the morning.
Conclusions
In conclusion, a replacement of limestone with 1% protected calcium can increase eggshell quality.
Implications
Protected-calcium supplementation can be used in practice for decreasing the breakage of eggs.

Abstract
Abstract Objective To discuss the application value of diatom examination in lung tissue for the forensic diagnosis of drowning. Methods The experimental animals were divided randomly into drowning, postmortem submergence and dying on land group. Diatoms in lung tissue and drowning fluid were analyzed quantitatively by microwave digestion-vacuum filtration-automated scanning electron microscopy diatom examination method. The ratios of content of diatoms in lung tissue and drowning fluid (CL/CD ratio) were recorded. Results The CL/CD ratios of experimental rabbits in the drowning group (5.82±3.50) were much higher than that of postmortem submergence group (0.47±0.35); the CL/CD ratios of different parts of the lung lobes of experimental pigs in the drowning group were higher than that of postmortem submergence group (P<0.05); in seawater, brackish water, river fresh water and lake fresh water, the CL/CD ratios of experimental pigs in the drowning group were higher than that of postmortem submergence group (P<0.05). In animal experiments, all the cases with CL/CD ratio >1.6 were from drowning group. Conclusion CL/CD ratio is an indicator with good application prospects in the diagnosis of drowning.

Abstract
OBJECTIVE To explore the expression and function of insulin-like growth factor II (IGFII) mRNA binding protein (IMP3) in the Triple Negative Breast Cancer (TNBC). MATERIALS AND METHODS According to previously reported gene expression array, we found that IMP3 had significantly higher expression in the CD44+CD24-ESA+ cell cluster, tumor initiating cell or cancer stem cell (CSCs), compared to other tumor cells. Based on the GEO database (GEO accession No. GSE6883), we detected the mRNA levels of IMP 1,2 and 3 by quantitative polymerase chain reaction (q-PCR) in CD44+CD24-ESA+ cell cluster and other breast tumor cell clusters. Besides, we measured IMP3 expression in microsphere of breast cancer, which exerted more significant tumor stem cell properties. The effects of IMP3 on breast cancer cell stem cell properties were studied by RNA interference and overexpression approaches in vitro. Furthermore, we predicted and identified microRNA, which could target and regulate IMP3 from bioinformatics analysis, and verified the interaction by luciferase assays and rescue experiments. RESULTS Previously reported data showed that IMP3 expression was significantly upregulated in CD44+CD24-ESA+ cell cluster from breast cancer tissues. Besides, we found IMP3 had higher expression in mesenchymal cells rather than epithelial cells, which was also significantly elevated in SUM159 and T49D cell lines cultured as microsphere rather than adherent cells or differentiated cells. CD44+CD24-ESA+ cell cluster proportion was significantly decreased after silencing IMP3 in SUM1315, and its ability to develop into microsphere was significantly inhibited. By re-expressing IMP3 in SUM315, we restored the self-renewal capacity and tumorigenesis potential of SUM315. Through relative predicting website, we found several miRNAs which could regulate IMP3. miR-34a with highest score was chosen for further analysis. Mimicking miR-34a significantly downregulated IMP3 expression and inhibited its ability to develop into microsphere, while overexpressing IMP3 could rescue this process. CONCLUSIONS IMP3 plays a vital role in maintaining stem cell properties of breast cancer cells, which could be regulated by mir-34a.

Abstract
OBJECTIVE Grape seed proanthocyanidin extract (GSPE), as one of the most popular natural drug extracted from the grape, has been reported to improve endothelial function and arteriosclerosis. However, little is known about the influence of GSPE on hypertension and vascular remodeling. Profilin-1, an Actin-binding protein, is closely involved in the remodeling of large vessels in ouabain-induced hypertension. To date, there is no effective prevention or treatment in place for the high incidence of ischemic stroke associated with hypertension. In this study, we aimed to determine the role of GSPE via inhibition Profilin-1 in ischemic cerebral cortices of ouabain-hypertension rats and potentially provide a new target to prevent stroke associated with hypertension. MATERIALS AND METHODS The blood pressure of male Sprague-Dawley (SD) rats was measured during a period of ouabain-induced hypertension. The expression of Profilin-1, vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS) in the cerebral cortex were determined by quantitative Real Time-PCR (qRT-PCR) and Western blot. Histopathological and behavioral tests were also conducted. RESULTS Blood pressure elevation started at week 5 and reached clinical standards for hypertension at week 8. GSPE was proved to suppress Profilin-1 and VEGF levels through inhibition of Profilin-1-protein kinase B (AKT)-hypoxia inducible factor-1α (HIF-1α) signal pathway and promote eNOS expression. Moreover, the histopathological and ethiological improvement was observed in GSPE over-expression and Profilin-1 inhibition groups. CONCLUSIONS We detected that GSPE could improve cerebral vascular damage through inhibiting Profilin-1 in an ouabain-induced hypertension model.

Muscle from grass-fed beef possessed nearly two-fold more (P < .05) succinate dehydrogenase and (P < .001) myoglobin than that of grain-fed cattle. These data show lean from grass-fed beef has greater enzymes reflective of oxidative metabolism and suggest dark lean from grass-fed cattle may be a function of more oxidative metabolism rather than a stress-related event antemortem.

[PMID: 31487417 DOI: 10.1111/jam.14433] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Revised: 08/20/2019] [Accepted: 08/22/2019] [Indexed: 01/10/2023]
Abstract
AIMS Lactic acid is a natural antimicrobial in food industry, and also exists in fermented food. It was reported that sublethally injured Escherichia coli could survive in acidic conditions. When conditions become advantageous, injured E. coli can restore physiological function, which is a potential threat in food industry. Recovery is a necessary step for discriminating injured bacteria, but the resuscitation mechanism of injured bacteria is still unknown. METHODS AND RESULTS In our study, sublethal lactic acid treatment (pH 4·2, 60 min) posed oxidative stress on E. coli by decrease of superoxide dismutase (SOD) activity and overproduction of reactive oxygen species (ROS). Zinc with low concentration (1·0 mmol l-1 ) significantly increased the recovery ratio of injured E.coli induced by lactic acid. The recovery ratios of injured cell in minimal A medium (minA) with 1·0 mmol l-1 zinc reached to that with 3·0 mmol l-1 catalase (CAT). Conversely, the addition of zinc chelator N, N, N', N'-tetrakis (2-pyridylmethyl) decreased the recovery ratio. Zinc accelerated resuscitation of injured E. coli by improving SOD activity, and decreasing ROS production. Deletion of sodC encoding Cu/ZnSOD, katE/katG encoding CAT or regulating gene rpoS significantly decreased the recovery ratio. Among all of the mutants in this study, ΔrpoS and ΔsodC showed the lowest recovery ratio, which means they played significant roles in the process of resuscitation. CONCLUSION We provided direct evidence that zinc mediated resuscitation of lactic acid-injured E. coli by relieving oxidative stress. Zinc can be used as a low-cost and effective agent to improve recovery ratio and detection efficiency of injured bacteria. SIGNIFICANCE AND IMPACT OF THE STUDY Antibacterial agents are a challenge for bacteria, but bacteria can survive as a sublethally injured state under stresses. Using injured E. coli induced by lactic acid as a model organism, we validated the significant role of zinc on resuscitation of injured cells.

Abstract
Objective: To detect phosphorylated-extracellular signal-regulated kinase (p-ERK1/2) protein expression in epithelial ovarian cancer and cell lines, and to examine the effects of mitogen-activated protein kinase (MAPK) kinase (MEK) inhibitor AZD6244 on cell proliferation, apoptosis as well as cell cycle of ovarian cancer cells. To explore the function and significance of MAPK/extracellular signal-regulated kinase (ERK) signaling pathway in the development of ovarian cancer. Methods: (1) A total of 104 cases of patients with ovarian cancer who accepted the treatment of gynecological surgery and being confirmed by pathological examination in First Affiliated Hospital, Dalian Medical University from January 2004 to December 2013 were selected. The expressions of p-ERK1/2 protein were detected by immunohistochemistry in ovarian cancer specimens, and the relationship between the expressions of p-ERK1/2 and the clinical features of patients was analyzed. (2) p-ERK1/2 and other related proteins were determined by western blot in various ovarian cancer cells, including SKOV3, OV2008, C13, A2780S, A2780CP, OVCAR4, OVCAR5, OVCAR8 and CAOV3 treated with or without MEK inhibitor. The cellular proliferation, apoptosis and cell cycle of ovarian cancer cells after treatment with MEK inhibitor were analyzed by methyl thiazolyl tetrazolium (MTT) assay and flow cytometry, respectively. Results: (1) The immunohistochemical method showed that p-ERK1/2 between low grade serous carcinoma and clear cell carcinoma were not significantly higher expressed (P>0.05) . However, a lower level of the p-ERK1/2 expression were observed among high grade serous carcinoma, mucinous carcinoma and endometrioid carcinoma (all P<0.05) . There was no significant correlation between the protein expression of p-ERK1/2 and patients' age, pathological stage of surgery, and preoperative serum CA(125) level (P>0.05). (2) Western blot showed that the protein p-ERK1/2 was widely expressed in various ovarian cancer cell lines such as SKOV3, OV2008, C13, A2780S, A2780CP, OVCAR4, OVCAR5, OVCAR8 and CAOV3. After treatment with AZD6244 (5, 10 μmol/L), the level of p-ERK1/2 in OVCAR5 and OVCAR8 decreased significantly in dose-dependent manner. Additionally, we found a reduction of the expression level of cyclin D1, caspase-3 and appeared cleaved poly adenosine diphosphate ribose polymerase (PARP) in OVCAR5 and OVCAR8, compared with control groups. MTT assays showed that OVCAR5, OVCAR8 and A2780S were differently inhibited in the dose-dependent manner after being treated with different concentrations of AZD6244 (0, 2.5, 5, 10, 25, 50 and 100 μmol/L, all P<0.05). Further tested by flow cytometry, the results showed that AZD6244 (5, 10 μmol/L) was able to induce the apoptosis of OVCAR5, OVCAR8 and A2780S, as well as G(0)/G(1) phase arrest, both in a dose-dependent manner (P<0.05). Conclusions: As the main active and functional unit of MAPK/ERK signaling pathway, p-ERK1/2 protein is expressed in both the tissues and various ovarian cancer cell lines. AZD6244 could down-regulated the expression of p-ERK1/2 in ovarian cancer cells, accompanied by the decreased proliferation and increased cell apoptosis of ovarian cancer cells. In conclusion, MAPK/ERK signaling pathway might play a role in the development and progression of ovarian cancer, and may be provide a novel option for molecular targeted therapies of the disease.

Abstract
Splenic injury is commonly encountered in severe blunt abdominal trauma. Technological improvements and the increasing availability of both diagnostic computed tomography (CT) and therapeutic splenic artery embolisation (SAE) are key factors in defining the high success rate of modern-day non-operative management (NOM) for blunt splenic injuries (BSIs). The Association for Surgery for Trauma (AAST) Organ Injury Scale (OIS) is commonly used by both radiologists and clinicians to stratify injury severity, traditionally based on the degree of parenchymal disruption seen on CT, and guide management. Its recent 2018 update takes splenic vascular injuries (i.e., active bleed, pseudoaneurysm, and traumatic arteriovenous fistulae) into consideration, the presence of which will indicate at least a grade IV (i.e., high-grade) injury. This is a reflection of the paradigm shift towards spleen conservation with regular use of SAE as the current standard of treatment. Prompted by the latest AAST OIS revision, which represents a more complete and current grading system, we present the spectrum of pertinent CT findings that the diagnostic radiologist should accurately identify and convey to the multidisciplinary trauma team (including the interventional radiologist). This review divides imaging findings based on the AAST OIS definitions and categorises them into (1) parenchymal and (2) vascular injuries. Features that may help in the detection of subtle BSIs are also described. Lastly, it touches on the key changes made to the new AAST OIS, substantiated by case illustrations.

Abstract
Objective: To analyze the clinical characteristics and explore the risk predictors on mortality in elderly patients with acute cholecystitis and cholangitis. Methods: We conducted a retrospective analysis of elderly patients hospitalized in the Second Medical Center of General Liberation Army Hospital for acute cholecystitis and cholangitis during 2000 to 2018. Clinical data and risk predictors on mortality were assessed. The patients were stratified into three groups based on age:Ⅰ (65-74 years old),Ⅱ (75-84 years old), and Ⅲ (≥85 years old). Logistic regression analysis was used to identify the predictors of mortality. Results: A total of 574 patients were finally enrolled with the mean age 87.6 years including 191 in group Ⅰ, 167 in group Ⅱ, and 216 in group Ⅲ. The main cause of acute cholecystitis and cholangitis was gallstone (76.3%),and the main symptom was abdominal pain (62.9%),followed by chills(62.5%),fever(59.8%),jaundice (47.2%) and septic shock(26.3%). Cholecystitis was the most common diagnosis in groups Ⅰ and Ⅱ,whereas it was cholangitis in group Ⅲ. Percutaneous transhepatic biliary/gallbladder drainage (PTBD/PTGD) and endoscopic retrograde cholangiopancreatography (ERCP) were administrated more frequently in groups Ⅲ. A total of 35 patients (6.1%) died during follow-up. Senior in age (OR=11.1),the Charlson comorbidity index (OR=19.5),cancers (OR=9.6),blood stream infections (OR=7.4),severity of cholecystitis and cholangitis (OR=4.2) were risk factors associated with mortality. Conclusions: Even in the elderly patients with acute cholecystitis and cholangitis,comorbidity is one of the main factors affecting clinical outcomes. Due to the poor performance, this group of population presents more severe disease and undergoes conservative treatment strategies.

Abstract
PURPOSE To evaluate the diagnostic performance of multi-modality functional imaging in differentiating malignant and benign thyroid 18F-fluorodeoxyglucose (18F-FDG) incidentaloma. METHODS This study included 87 patients with thyroid 18F-FDG incidentalomas detected by 18F-FDG- positron emission tomography/computed tomography (18F-FDG-PET/CT) and diagnosed at surgery or biopsy, who received 18F-FDG-PET/CT, diffusion-weighted MR imaging (DWI) and ultrasound elastography (USE). The metabolic tumor volume (MTV), total lesion glycolysis (TLG), apparent diffusion coefficient (ADC) values and ultrasound elasticity scores of thyroid 18F-FDG incidentalomas were measured and compared in benign and malignant thyroid incidentalomas. The differences of malignant and benign thyroid incidentalomas were tested by χ2 test, Fisher's exact test, t test, or Mann-Whitney U test. The diagnostic performance was evaluated and optimal cut-off values were determined in distinguishing malignant from benign thyroid incidentalomas by receiver operating characteristic curve analysis. RESULTS MTV, TLG and USE scores of malignant thyroid incidentalomas were significantly higher than benign; but ADC value was significantly lower. We defined the functional imaging parameters TLG < 2.48, ADC > 1.80 × 10-3mm2/s, and USE score of 1 as markers of benign thyroid incidentalomas and each scored -1 point; TLG ≥ 2.48, ADC ≤ 1.80 × 10-3mm2/s, and USE score of 4 as markers of malignancy and each scored 1 point. Combined multi-functional imaging parameters achieved the highest performance (84.6% sensitivity and 97.1% specificity) for distinguish malignant from benign thyroid incidentaloma with AUC 0.957 (95% CI 0.917, 0.997). CONCLUSIONS Functional imaging might help to distinguishing malignant from benign thyroid 18F-FDG incidentalomas, and combined multi-functional imaging parameters could improve it.

Abstract
Cold-adapted trees display acclimation in both carbon source and carbon sink capacity to low-temperature stress at their upper elevational range limits. Hence a balanced carbon source-sink capacity might be required for their persistence and survival at the elevational tree limits. The present study examined the spatial dynamics of carbon source-sink relationship in subalpine fir (Abies fargesii) trees along elevational gradients in the northern slope of the temperate region and in the southern slope of the subtropics in terms of climate in the Qinling Mountain range, north-central China. The results showed that non-structural carbohydrate (NSC) concentrations in both the source and sink tissues increased with the increase in elevation. The ratio of carbon source-sink displayed a consistent decreasing trend with the increase in elevation and during growing season, showing that it was lowest at a ratio of 2.93 in the northern slope and at a ratio of 2.61 in the southern slope at the upper distribution elevations in the late growing season. Such variations of carbon source-sink ratio might be attributable to the balance between carbon source and sink activities, which changed seasonally across the elevational distribution range. We concluded that a ratio of carbon source-sink of at least 2.6 might be essential for subalpine fir trees to persist at their upper range limits. Therefore, a sufficient source-sink ratio and a balanced source-sink relationship might be required for subalpine fir trees to survive and develop at their upper elevational distribution limits.

Abstract
The main steps for the analysis of the Λp correlated production in low-energy K− captures on Carbon nuclei, performed by the AMADEUS collaboration, are presented. The goal is to perform the first comprehensive study of the K− absorption on two, three and four nucleons, exploiting the lowmomentum K−s (pK ~ 127 MeV/c) produced at the DAΦNE collider, and to measure the low-energy cross sections and branching ratios of the K− multinucleon absorption processes in both the Λp and Σ0p channels. An integrated luminosity of 1.74 fb−1 collected during the KLOE 2004/2005 data campaign is analysed by reconstructing the Λp final state.

Abstract
The interaction of antikaons (K−) with nucleons and nuclei in the low-energy regime represents a very active research field in hadron physics. A unique and rather direct experimental access to the antikaon-nucleon scattering lengths is provided by precision X-ray spectroscopy of transitions in low-lying states in the lightest kaonic atoms (i.e. kaonic hydrogen and deuterium). In the SIDDHARTA experiment at the electron-positron collider DAFNE of LNFINFN we measured the most precise values of the strong interaction observables in conic hydrogen. The strong interaction on the 1s ground state of the electromagnetically bound K-p atom causes an energy shift and broadening of the 1s state. SIDDHARTA will extend the spectroscopy to kaonic deuterium to get access to the antikaon-neutron interaction and thus the isospin dependent scattering lengths. At J-PARC a kaon beam is used in a complementary experiment with a different setup for spectroscopy of kaonic deuterium atoms. The talk will give an overview of the of the upcoming experiments SIDDHARTA and the complementary experiment at J-PARC.Furthermore, the implications of the experiments for the theory of low-energy strong interaction with strangeness will be discussed.

Abstract
OBJECTIVE Catastrophic antiphospholipid syndrome (CAPS), also known as Asherson's syndrome, is a special subtype of antiphospholipid syndrome (APS) characterized by multiple intravascular thrombosis involving multiple organs systems or tissues simultaneously or continuously, high titer antiphospholipid antibodies and high mortality rate. This article's aims was to analyze the clinical manifestation, laboratory examination and treatment therapy of CAPS for the purpose of improving the understanding, diagnosis and treatment of the disease in clinical practice. METHODS Retrospective analysis and descriptive statistics were applied to the clinical manifestations and laboratory findings of 14 CAPS cases from APS Shanghai Database (APS-SH) with catastrophic antiphospholipid. RESULTS Of the 14 CAPS patients, 12 cases satisfied the 2003 CAPS Classification Criteria accepted in the 10th International Congress on Antiphospholipid Antibody, and were diagnosed as definite APS and 2 cases were diagnosed as probable CAPS. Three cases were categorized as primary APS and 11 as APS secondary to systemic lupus erythematosus (SLE). Infection was mostly commonly seen before the onset of CAPS, followed by SLE activity and surgery. Among the involved organs, systems and tissues, brain and lung were most commonly affected sites of arterial thrombosis while peripheral vein was most commonly affected in venous thrombosis events among the clinical events. Triple positivity of anticardiolipin antibody (aCL), anti-β2 glyeoprotein I antibody (aβ2GPI), lupus anticoagulant (LA) were detected in 54.55% of the patients. Thrombocytopenia and decreased hemoglobin were frequently seen in the CAPS patients, and the majority proved to be hemolytic anemia. Of all the cases, 6 ended with death. The triple therapy strategy (anticoagulants, glucocorticoid, intravenous immunoglobulin and/or plasma exchange) could help to improve prognosis, cyclophosphamide and rituximab might benefit the patients with other comorbidities such as SLE and micro-angiopathic hemolytic anemia (MHA). CONCLUSION CAPS patients suffer from life-threatening acute multiple small vessel thrombosis with high titer of antiphospholipid antibody, potentially leading to multiple organ failure and a poor prognosis, thus early diagnosis and sufficient treatment are critical to prevent the progression of disease and improve the prognosis.

Abstract
Fruit flies in the genus Bactrocera are global, economically important pests of agricultural food crops. However, basic life history information about these pests, which is vital for designing more effective control methods, is currently lacking. Artificial diets can be used as a suitable replacement for natural host plants for rearing fruit flies under laboratory conditions, and this study reports on the two-sex life-table parameters of four Bactrocera species (Bactrocera correcta, Bactrocera dorsalis, Bactrocera cucurbitae, and Bactrocera tau) reared on a semi-artificial diet comprising corn flour, banana, sodium benzoate, yeast, sucrose, winding paper, hydrochloric acid and water. The results indicated that the larval development period of B. correcta (6.81 ± 0.65 days) was significantly longer than those of the other species. The fecundity of B. dorsalis (593.60 eggs female-1) was highest among the four species. There were no differences in intrinsic rate of increase (r) and finite rate of increase (λ) among the four species. The gross reproductive rate (GRR) and net reproductive rate (R0) of B. dorsalis were higher than those of the other species, and the mean generation time (T) of B. cucurbitae (42.08 ± 1.21 h) was longer than that of the other species. We conclude that the semi-artificial diet was most suitable for rearing B. dorsalis, due to its shorter development time and higher fecundity. These results will be useful for future studies of fruit fly management.

Abstract
Background and Aim:Post-traumatic hydrocephalus is a common complication that arises after head injury. However, risk factors associated with the outcome of post-traumatic hydrocephalus have seldom been addressed. Therefore, we performed this clinical study to analyze the risk factors affecting the outcome of post-traumatic hydrocephalus in patients with head injuries.Methods:A total of 116 post-traumatic hydrocephalus patients, admitted in our hospital between March 2012 and October 2017 were reviewed. The related factors assessed were age, gender, Glasgow Coma Score on admission, platelet count, plasma fibrinogen levels, D-dimer concentration, subarachnoid hemorrhage, subdural hygroma, cerebral hernia, cisterna ambiens, decompressive craniectomy, cranioplasty, ventriculoperitoneal shunt implantation, intracranial infection, and duration of comatous state. The patient outcomes after 6 months of treatment were evaluated by the Glasgow Outcome Scale. Risk factors for the outcome of post-traumatic hydrocephalus were evaluated by applying logistic regression analysis.Results:Poor outcome was observed in 66.4% of the patients (77/116). Univariate and multivariate analyses revealed that the disappearance of cisterna ambiens, the long duration of comatous state (>2 months), the high levels of plasma fibrinogen, and the ventriculoperitoneal shunt implantation were related to adverse outcomes (p < 0.05).Conclusion:The disappearance of cisterna ambiens, the prolonged duration of comatous state (>2 months), the high plasma fibrinogen levels are the most important factors affecting the outcome of post-traumatic hydrocephalus, and the ventriculoperitoneal shunt implantation is the most critical predictor of the outcome of post-traumatic hydrocephalus.

Abstract
Objective: To explore the association between hypothyroidism and sleep breathing disorders in patients with coronary heart disease (CHD). Methods: A total of 784 patients with CHD were consecutively enrolled at the Emergency & Critical Care Center of Beijing Anzhen Hospital from June 2015 to May 2017. According to thyroid function test results, patients were divided into hypothyroidism group (79 cases) and non-hypothyroidism group (705 cases). All patients had undergone sleep monitoring. The sleep apnea status was compared between the two groups. Multivariate logistic regression and linear regression models were used to analyze the association between hypothyroidism and sleep breathing disorders in patients with CHD. Results: The proportion of females, mean body weight and body mass index in the hypothyroidism group were higher than those in the non-hypothyroidism group [26.6% vs.16.2%, (78.6±11.6) kg vs. (75.7±12.0) kg, (27.7±3.2) kg/m(2) vs. (26.6±3.5) kg/m(2), all P<0.05]. Patients in hypothyroidism group had a decreased average oxygen saturation (SaO(2)) compared with patients in non-hypothyroidism group [ (93.2±2.9) % vs. (93.9±2.0) %, P=0.030]. In addition, events of hypoventilation in hypothyroidism group were significantly higher than those in non-hypothyroidism group[92.5 (45.8, 758.3) times vs. 68.0 (33.0, 125.0) times, P=0.013]. There were no significant differences in apnea hypopnea index, diagnosis of obstructive sleep apnea and other sleep breathing parameters between the two groups (P>0.05). A multiple linear regression analysis found that in patients with CHD, the correlation between hypothyroidism and average sleep SaO(2) was significant (β=-0.508, 95%CI -0.989--0.026, P=0.039). Conclusions: CHD patients with hypothyroidism had a lower sleep average SaO(2), and a higher sleep hypopnea events. There is a correlation between hypothyroidism and sleep hypoxia in patients with CHD. Clinical trial registration: clinicalTrials.gov, NCT03362385.

Abstract
Objective: To evaluate the efficacy, bleeding profile and safety of low-dose levonorgestrel-releasing intrauterine system (LNG-IUS 8) in Chinese healthy women of childbearing age. Methods: A multi-center, open-label, single-arm clinical trial conducted at 16 centres in China enrolled 773 healthy women of childbearing age (mean age 31.6 years old, range 18 to 40 years old) , who demanded contraception, from April 2006 to June 2013. All women placed LNG-IUS 8 for 3 years and then been followed up at 3, 6, 9, 12, 18, 24, 30, 36 months. The efficacy variables including pregnancy rate and expulsion rate were analyzed using life table, while observing adverse events (AE) to evaluate the safety. The bleeding profile happened during the study was assessed using 90-day reference intervals (World Health Organization criteria) . Results: Eight pregnancies occurred among 773 women, resulting in a overall Pearl index of 0.42 per 100 women years. The 3-year cumulative pregnancy rate was 0.37 per 100 women years and the 3-year cumulative expulsion rate was 1.99 per 100 women years. The number of women with bleeding/spotting reduced and the bleeding/spotting days declined over time. Totally 219 AE were reported related to LNG-IUS 8 placements. The most common AE were vaginal bleeding (8.2%, 63/773) and the ovarian cyst (6.2%, 52/773) . LNG-IUS 8 had an improving effect on dysmenorrhea that the percentage of women with dysmenorrhea as well as the days of dysmenorrhea decreased over time. The percentage of women satisfied or very satisfied with LNG-IUS 8 was 87.2% (622/713) . Conclusion: LNG-IUS 8 is highly effective and safe for Chinese healthy women of childbearing age.

Abstract
Glanzmann's thrombasthenia (GT) is a rare bleeding disorder characterized by spontaneous mucocutaneous bleeding. The disorder is caused by quantitative or qualitative defects in integrin αIIbβ3 (encoded by ITGA2B and ITGB3) on the platelet and is more common in consanguineous populations. However, the prevalence rate and clinical characteristics of GT in non-consanguineous populations have been unclear. We analyzed 97 patients from 93 families with GT in the Han population in China. This analysis showed lower consanguinity (18.3%) in Han patients than other ethnic populations in GT-prone countries. Compared with other ethnic populations, there was no significant difference in the distribution of GT types. Han females suffered more severe bleeding and had a poorer prognosis. We identified a total of 43 different ITGA2B and ITGB3 variants, including 25 previously unidentified, in 45 patients. These variants included 14 missense, 4 nonsense, 4 frameshift, and 3 splicing site variants. Patients with the same genotype generally manifested the same GT type but presented with different bleeding severities. This suggests that GT clinical phenotype does not solely depend on genotype. Our study provides an initial, yet important, clinical and molecular characterization of GT heterogeneity in China.

Abstract
Satellite cells (SCs) reside between the sarcolemma and basal lamina of muscle fibers and are the primary contributor of DNA for post-hatch muscle growth and repair. Alterations in SC content or properties by intrinsic and extrinsic factors can have detrimental effects on muscle health and function, and ultimately meat quality. We hypothesized that disrupted SC homeostasis may account in part for the increased breast myopathies observed in growing broilers. To test this hypothesis, we selected broilers with different body weights at comparable ages and studied SC characteristics in vitro and in vivo. Data shows that SC numbers in the breast muscles decrease (P < 0.001) and their inherent abilities to proliferate and differentiate diminish (P < 0.001) with age and size. Further, when breast muscle is presented with an insult, muscle of larger broilers regenerates more slowly than their smaller, age-matched counterparts arguing that SC quality changes with size and age. Together, our studies show that birds with greater muscle hypertrophy have less SCs with diminished ability to function, and suggest that aggressive selection for breast growth in broilers may exhaust SC pools when birds are grown to heavier processing weights. These findings provide new insights into a possible mechanism leading to breast myopathies in the poultry industry and provide targets for mitigating adverse fresh breast quality.
