Constraints on Cosmic Strings Using Data from the Third Advanced LIGO-Virgo Observing Run. PHYSICAL REVIEW LETTERS 2021; 126:241102. [PMID: 34213926 DOI: 10.1103/physrevlett.126.241102] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/30/2021] [Revised: 03/31/2021] [Accepted: 05/23/2021] [Indexed: 06/13/2023]
Abstract
We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension Gμ as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models. Additionally, we develop and test a third model that interpolates between these two models. Our results improve upon the previous LIGO-Virgo constraints on Gμ by 1 to 2 orders of magnitude depending on the model that is tested. In particular, for the one-loop distribution model, we set the most competitive constraints to date: Gμ≲4×10^{-15}. In the case of cosmic strings formed at the end of inflation in the context of grand unified theories, these results challenge simple inflationary models.

Measurement of the Cosmic Ray Helium Energy Spectrum from 70 GeV to 80 TeV with the DAMPE Space Mission. PHYSICAL REVIEW LETTERS 2021; 126:201102. [PMID: 34110215 DOI: 10.1103/physrevlett.126.201102] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Revised: 03/25/2021] [Accepted: 04/06/2021] [Indexed: 06/12/2023]
Abstract
The measurement of the energy spectrum of cosmic ray helium nuclei from 70 GeV to 80 TeV using 4.5 years of data recorded by the Dark Matter Particle Explorer (DAMPE) is reported in this work. A hardening of the spectrum is observed at an energy of about 1.3 TeV, similar to previous observations. In addition, a spectral softening at about 34 TeV is revealed for the first time with large statistics and well controlled systematic uncertainties, with an overall significance of 4.3σ. The DAMPE spectral measurements of both cosmic protons and helium nuclei suggest a particle charge dependent softening energy, although with current uncertainties a dependence on the number of nucleons cannot be ruled out.

Abstract
Objective: Donor cytomegalovirus (CMV) serological negative status may have an adverse effect on the outcome of allogeneic hematopoietic stem cell transplantation (allo-HSCT), while there is inadequate data for Chinese people. This study is to explore the impact of donor CMV serological status on the outcome of CMV seropositive patients receiving allo-HSCT. Methods: Our study retrospectively analyzed 16 CMV seropositive patients with hematological malignancies receiving allogeneic grafts from CMV seronegative donors (antibody IgG negative) at Peking University People's Hospital from March 2013 to March 2020, which was defined as D-/R+ group. The other 64 CMV seropositive patients receiving grafts from CMV seropositive donors at the same period of time were selected as matched controls through a propensity score with 1∶4 depending on age, disease state and donor-recipient relationship (D+/R+ group). Results: Patients in D-/R+ group developed CMV DNAemia later than patients in the D+/R+ group (+37 days vs. +31 days after allo-HSCT, P=0.011), but the duration of CMV DNAemia in D-/R+ group was longer than that of D+/R+ group (99 days vs. 34 days, P=0.012). The rate of CMV reactivation 4 times or more in D-/R+ group was 4/16, significantly higher than that of D+/R+ group (4.7%, 3/64, P=0.01). The incidences of refractory CMV DNAemia (14/16 vs. 56.3%, P=0.021) and CMV disease (4/16 vs. 4.7%, P=0.01) in D-/R+ group were both higher than those in D+/R+ group. In addition, the application of CMV-CTL as the second-line antiviral treatment in D-/R+ group was more than that in D+/R+ group. Univariate analysis and multivariate analysis suggested that CMV serological negativity is an independent risk factor for refractory CMV DNAemia and the duration of CMV infection. The cumulative incidence of aGVHDⅡ-Ⅳ, cGVHD, 3-year probability of NRM, overall survival, and the cumulative incidence of relapse were all comparable in two groups. Conclusions: Although there is no significant effect on OS and NRM, the incidence of refractory CMV DNAemia, the frequency of virus reactivation, and the development of CMV disease in D-/R+ group are higher than those in controls. Therefore, CMV seropositive donors are preferred for CMV seropositive patients.

Abstract
Uveal melanoma (UM) is the most common primary intraocular malignancy in adults. Important cytogenetic and genetic risk factors for the development of UM include chromosome 3 monosomy, mutations in the guanine nucleotide-binding proteins GNAQ/GNA11, and loss of the BRACA1-associated protein 1 (BAP 1). Most primary UMs are treated conservatively with radiotherapy, but enucleation is necessary for large tumours. Despite the effectiveness of local control, up to 50% of UM patients develop metastasis for which there are no effective therapies. Attempts to utilise the targeted therapies that have been developed for the treatment of other cancers, including a range of signal transduction pathway inhibitors, have rarely produced significant outcomes in UM. Similarly, the application of immunotherapies that are effective in cutaneous melanoma to treat UM have also been disappointing. Other approaches that have been initiated involve proteasomal inhibitors and histone deacetylase inhibitors which are approved for the treatment of other cancers. Nevertheless, there have been occasional positive outcomes from these treatments in UM. Moreover, combination approaches in UM have also yielded some positive developments. It would be valuable to identify how to apply such therapies efficiently in UM, potentially via individualised tumour profiling. It would also be important to characterise UM tumours to differentiate the potential drivers of progression from those in other types of cancers. The recent identification of novel kinases and metastatic genes in UM tumours makes the development of new UM-specific treatments feasible.

Abstract
Severe burns trigger the stress response, cause different degrees of damage to the body, and participate in the occurrence and development of immune dysfunction and hypermetabolism after burn. Rational application of analgesic and sedative drugs is the major method of inhibiting the severe burn-induced stress response, which can alleviate the organ damages and reduce the incidence of burn sepsis. Furthermore, integrated approaches including wound management, infection control, nutritional support, and gastrointestinal tract protection, as well as sleep management, etc., collectively contribute to the alleviation of stress response after burn injury. To further improve the success rate of severe burn treatment, it is essential to study the changes of various stresses, endocrine hormones and immune patterns in patients with severe burn, to explore the mechanism and regulation of burn-induced hypermetabolism, and to reach a consensus on sedation and analgesia strategy, the management of stress response and hypermetabolism after severe burns.

Abstract
Objective: To investigate the effects of hypoxia-pretreated rat adipose-derived mesenchymal stem cells (ADSCs) conditioned medium on wound healing of rats with full-thickness defects. Methods: (1) A 6-week-old male Sprague-Dawley rat was sacrificed by cervical dislocation, the bilateral inguinal adipose tissue was collected, the third generation ADSCs were isolated by collagenase digestion method, and the cells morphology was observed. The cells were harvested and divided into adipogenic induction group and osteogenic induction group according to the random number table (the same grouping method below), with 6 wells in each group. The cells in adipogenic induction group were cultured for 14 days to observe adipogenesis, and cells in osteogenic induction group were cultured for 28 days to observe osteogenesis. (2) The third generation ADSCs were collected and divided into normoxic group and hypoxic group. Cells in normoxic group was incubated in normal oxygen incubator with oxygen volume fraction of 21%, and cells in hypoxic group was incubated in low oxygen incubator with oxygen volume fraction of 2% respectively, with 3 samples in each group for each time point. Three samples in normoxic group on 3 h of culture and in hypoxic group on 3, 6, 12, 24, and 48 h of culture were collected for detecting the following indexes. The mRNA expressions of hypoxia inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and peroxisome proliferator-activated receptor γ (PPAR-γ) were detected by real time fluorescent quantitative reverse transcription polymerase chain reaction. The cell culture supernatant in the two groups was collected, centrifuged, and filtered to obtain normoxic conditioned medium (normo-CM ) and hypoxic conditioned medium (hypo-CM). Enzyme linked immunosorbent assay was used to detect content of VEGF, transforming growth factor β (TGF-β), epidermal growth factor (EGF), and insulin-like growth factor (IGF) in conditioned medium. (3) Twenty-seven male Sprague-Dawley rats aged 6-8 weeks were collected and divided into phosphate buffer solution (PBS) group, normo-CM group, and hypo-CM group, with 9 rats in each group. A circular full-thickness skin defect wound with diameter of 1 cm was made on the back of each rat, and the wounds of rats in PBS, normo-CM, and hypo-CM groups were respectively dropped with 50 μL PBS, normo-CM, and hypo-CM. On post injury day (PID) 0, 3, 5, 7, 9, and 11, the gross condition of wound was observed, wound area was measured, and the non-healing rate of wound was calculated. The wound tissue was collected for hematoxylin eosin staining to observe inflammatory reaction of wound on PID 3, 9, and 11 and re-epithelialization of wound on PID 9. Masson staining was used to observe the collagen deposition and analyze collagen volume fraction of wound on PID 11. Data were statistically analyzed with analysis of variance for repeated measurement, one-way analysis of variance, t test, and Bonferroni correction. Results: (1) The isolated cells showed a fusiform, in adherent growth and close arrangement when in low fusion degree. On 14 d of culture, the red lipid droplets stained with oil red O were observed in cells in adipogenic induction group, and on 28 d of culture, the red nodules stained with alizarin red S were observed in cells in osteogenic induction group. The cells were identified as ADSCs. (2) Compared with that in normoxic group, the mRNA expression of HIF-1α was significantly increased at 12 and 24 h of culture (t=5.43, 5.11, P<0.05), the mRNA expression of VEGF was significantly increased at 6 and 12 h of culture (t=3.29, 2.33, P<0.05 or P<0.01), the mRNA expression of bFGF was significantly increased at 12 h of culture (t=12.59, P<0.01) and significantly reduced at 48 h of culture (t=9.34, P<0.01), and the mRNA expression of PPAR-γ was significantly reduced at 3, 12, and 24 h of culture in hypoxic group (t=5.14, 6.56, 4.97, P<0.05). (3) Compared with that in normoxic group, the VEGF content was significantly increased at 3, 6, 12, 24, and 48 h of culture (t=5.74, 12.37, 14.80, 15.70, 34.63, P<0.05 or P<0.01), and the IGF content was significantly increased at 6, 12, 24, and 48 h of culture (t=5.65, 8.06, 20.12, 22.99, P<0.05 or P<0.01), and the content of TGF-β and EGF showed no obvious change at 3, 6, 12, 24, and 48 h of culture in hypoxic group. (4) From PID 0 to 11, the wound of rats in the three groups shrank to varying degrees, with no obvious infection or exudate. On PID 11, the wound area of rats in PBS group was still large, which was larger than that in normo-CM group, and the wound area of rats in hypo-CM group was basically healed. On PID 0, 3, and 5, the non-healing rates of wound of rats in the three groups were similar. On PID 7, the non-healing rates of wound of rats in normo-CM and hypo-CM groups were significantly lower than that in PBS group (t=10.26, 16.03, P<0.05). On PID 9, the non-healing rate of wound of rats in hypo-CM group was significantly lower than that of PBS group and normo-CM group, respectively (t=17.25, 6.89, P<0.05 or P<0.01), and the non-healing rate of wound of rats in normo-CM group was significantly lower than that in PBS group (t=8.81, P<0.05). On PID 11, the non-healing rate of wound of rats in hypo-CM group was (2.4±1.5)%, which was significantly lower than (20.0±5.0)% in PBS group and (7.7±1.7)% in normo-CM group (t= 30.15, 84.80, P<0.05). (5) On PID 3, the infiltration of inflammatory cells in the wound of rats in hypo-CM group was obviously more than those in the other two groups. On PID 9, the infiltration of inflammatory cells in the wound of rats in hypo-CM and normo-CM groups was obviously less than that in PBS group. On PID 11, the infiltration of inflammatory cells in the wound of rats in hypo-CM group was obviously less than those in PBS and normo-CM groups. On PID 9, the length of " epidermal migration tongue" on the wound of rats in hypo-CM group was longer than those of the other two groups, and the epidermis thickness was close to normal skin. On PID 11, compared with those in PBS and normo-CM groups, a large number of collagen deposits with dense structure, neat arrangement, and higher maturity were seen in the wound of rats in hypo-CM group. The wound collagen volume fraction of rats in PBS group was (22.90±1.25)%, which was significantly lower than (31.96±0.14)% in normo-CM group and (56.10±1.50)% in hypo-CM group (t=12.48, 29.43, P<0.05), and the wound collagen volume fraction of rats in normo-CM group was significantly lower than that in hypo-CM group (t=27.73, P<0.05). Conclusions: Hypoxia-pretreated can significantly enhance paracrine effect of rat ADSCs. Hypoxia-pretreated rat ADSC conditioned medium can accelerate the healing of full-thickness skin defect wound in rats by regulating inflammatory cell infiltration, promoting re-epithelialization and collagen deposition in the wound.

GW190521: A Binary Black Hole Merger with a Total Mass of 150 M_{⊙}. PHYSICAL REVIEW LETTERS 2020; 125:101102. [PMID: 32955328 DOI: 10.1103/physrevlett.125.101102] [Citation(s) in RCA: 73] [Impact Index Per Article: 18.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 06/19/2020] [Accepted: 07/09/2020] [Indexed: 06/08/2023]
Abstract
On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of 85_{-14}^{+21} M_{⊙} and 66_{-18}^{+17} M_{⊙} (90% credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65 M_{⊙}. We calculate the mass of the remnant to be 142_{-16}^{+28} M_{⊙}, which can be considered an intermediate mass black hole (IMBH). The luminosity distance of the source is 5.3_{-2.6}^{+2.4} Gpc, corresponding to a redshift of 0.82_{-0.34}^{+0.28}. The inferred rate of mergers similar to GW190521 is 0.13_{-0.11}^{+0.30} Gpc^{-3} yr^{-1}.

Abstract
Prostate cancer (Pca) is the second frequent malignancy in men. Long noncoding RNAs (lncRNAs) have been reported to play essential roles in the progression of cancers, including Pca. LncRNA colorectal neoplasia differentially expressed (CRNDE) has been found to affect tumorigenesis in many cancers. However, the exact role and mechanism of CRNDE in Pca remain poorly understood. 64 Pca patients were recruited in this study. PC3 and 22RV1 cells were used in vitro experiments. The expressions of CRNDE, microRNA-101 (miR-101), and Ras-related protein 1A (Rap1A) were detected in vivo and in vitro by quantitative real-time polymerase chain reaction and western blot, respectively. Cell proliferation, apoptosis, migration, and invasion were investigated through cell counting kit-8, flow cytometry, and Transwell assays, respectively. The interaction between miR-101 and CRNDE or Rap1A was explored by bioinformatics analysis and luciferase reporter assay. High expression of CRNDE was shown in Pca tissues and cells and predicted poor outcomes of patients. Overexpression of CRNDE promoted cell proliferation, migration, and invasion but decreased apoptosis in Pca cells, while its knockdown showed an opposite effect. CRNDE was a decoy of miR-101 and its effect on Pca progression was reversed by miR-101. Rap1A was identified as a target of miR-101 and it attenuated the effect of miR-101 on Pca development. Moreover, the Rap1A protein level was positively regulated by CRNDE, which was weakened by miR-101. CRNDE contributed to cell proliferation, migration, and invasion by regulating the miR-101/Rap1A axis in Pca, providing a novel strategy for Pca treatment.

Abstract
Objective: To investigate the diagnosis and treatment for enterocutaneous fistula (ECF) in China, and to explore the prognostic factors of ECF. Methods: A multi-center cross-sectional study was conducted based on the Registration System of Chinese Gastrointestinal Fistula and Intra-Abdominal Infections to collect the clinical data of ECF patients from 54 medical centers in 22 provinces/municipalities from January 1, 2018 to December 31, 2018. The clinical data included patient gender, age, length of hospital stay, intensive care unit (ICU) admission, underlying diseases, primary diseases, direct causes of ECF, location and type of ECF, complications, treatment and outcomes. All medical records were carefully filled in by the attending physicians, and then re-examined by more than two specialists. The diagnosis of ECF was based on the clinical manifestations, laboratory/imaging findings and intraoperative exploration. Results: A total of 1521 patients with ECF were enrolled, including 1099 males and 422 females, with a median age of 55 years. The top three primary diseases of ECF were malignant tumors in 626 cases (41.2%, including 540 gastrointestinal tumors, accounting for 86.3% of malignant tumors), gastrointestinal ulcers and perforations in 202 cases (13.3%), and trauma in 157 cases (10.3%). The direct causes of ECF were mainly surgical operation in 1194 cases (78.5%), followed by trauma in 156 (10.3%), spontaneous fistula due to Crohn's disease in 92 (6.0%), radiation intestinal injury in 41 (2.7%), severe pancreatitis in 20 (1.3%), endoscopic treatment in 13 (0.9%) and 5 cases (0.3%) of unknown reasons. All the patients were divided into three groups: 1350 cases (88.7%) with simple ECF, 150 (9.9%) with multiple ECF, and 21 (1.4%) with combined internal fistula. Among the patients with simple ECF, 438 cases (28.8%) were jejuno-ileal fistula, 313 (20.6%) colon fistula, 170 (11.2%) rectal fistula, 111 (7.3%) duodenal fistula, 76 (5.0%) ileocecal fistula, 65 (4.3%) ileocolic anastomotic fistula, 55 (3.6%) duodenal stump fistula, 36 (2.4%) gastrointestinal anastomotic fistula, 36 (2.4%) esophagogastric/esophagojejunal anastomotic fistula, 29 (1.9%) gastric fistula and 21 (1.4%) cholangiopancreatiointestinal. Among all the simple ECF patients, 991 were tubular fistula and 359 were labial fistula. A total of 1146 patients finished the treatment, of whom 1061 (92.6%) were healed (586 by surgery and 475 self-healing) and 85 (7.4%) died. A total of 1043 patients (91.0%) received nutritional support therapy, and 77 (6.7%) received fistuloclysis. Infectious source control procedures were applied to 1042 patients, including 711 (62.0%) with active lavage and drainage and 331 (28.9%) with passive drainage. Among them, 841 patients (73.4%) underwent minimally invasive procedures of infectious source control (replacement of drainage tube through sinus tract, puncture drainage, etc.), 201 (17.5%) underwent laparotomy drainage, while 104 (9.1%) did not undergo any drainage measures. A total of 610 patients (53.2%) received definitive operation, 24 patients died within postoperative 30-day with mortality of 3.9% (24/610), 69 (11.3%) developed surgical site infection (SSI), and 24 (3.9%) had a relapse of fistula. The highest cure rate was achieved in ileocecal fistula (100%), followed by rectal fistula (96.2%, 128/133) and duodenal stump fistula (95.7%,44/46). The highest mortality was found in combined internal fistula (3/12) and no death in ileocecal fistula. Univariate prognostic analysis showed that primary diseases as Crohn's disease (χ(2)=6.570, P=0.010) and appendicitis/appendiceal abscess (P=0.012), intestinal fistula combining with internal fistula (χ(2)=5.460, P=0.019), multiple ECF (χ(2)=7.135, P=0.008), esophagogastric / esophagojejunal anastomotic fistula (χ(2)=9.501, P=0.002), ECF at ileocecal junction (P=0.012), non-drainage/passive drainage before the diagnosis of intestinal fistula (χ(2)=9.688, P=0.008), non-drainage/passive drainage after the diagnosis of intestinal fistula (χ(2)=9.711, P=0.008), complicating with multiple organ dysfunction syndrome (MODS) (χ(2)=179.699, P<0.001), sepsis (χ(2)=211.851, P<0.001), hemorrhage (χ(2)=85.300, P<0.001), pulmonary infection (χ(2)=60.096, P<0.001), catheter-associated infection (χ(2)=10.617, P=0.001) and malnutrition (χ(2)=21.199, P<0.001) were associated with mortality. Multivariate prognostic analysis cofirmed that sepsis (OR=7.103, 95%CI:3.694-13.657, P<0.001), complicating with MODS (OR=5.018, 95%CI:2.170-11.604, P<0.001), and hemorrhage (OR=4.703, 95%CI: 2.300-9.618, P<0.001) were independent risk factors of the death for ECF patients. Meanwhile, active lavage and drainage after the definite ECF diagnosis was the protective factor (OR=0.223, 95%CI: 0.067-0.745, P=0.015). Conclusions: The overall mortality of ECF is still high. Surgical operation is the most common cause of ECF. Complications e.g. sepsis, MODS, hemorrhage, and catheter-associated infection, are the main causes of death. Active lavage and drainage is important to improve the prognosis of ECF.

Abstract
Objective: To understand the prevalence, diagnosis and treatment of chronic critical illness (CCI) in China. Methods: The clinical data of 472 adult patients admitted to ICU in 53 hospitals, including basic information, disease-related data, nutrition program, etc., were collected on May 10, 2019, by means of multi-center cross-sectional study. If surgical intervention was needed or the occurrence of the disease was directly related to the surgery, ICU patients were regarded as surgical ICU cases (n=211). In this study, the diagnostic criteria for CCI were: (1) admission to ICU >14 days;(2) combined with persistent organ dysfunction. The prevalence,distribution and treatment of CCI and surgery-related CCI were recorded and analyzed. The Mann-Whitney U test, chi-square test or Fisher exact test were used for comparative analysis. Results: Among the 472 ICU patients from 53 hospitals, 326 were male (69.1%) and 146 were female (30.9%). The prevalence of CCI was 30.7% (145/472). Among 211 surgery-related ICU patients, 57 developed CCI with a prevalence of 27.0%. As compared to non-CCI patients, higher APACHE II score [median (IQR) 13.5 (10.0, 18.3) vs. 11.0 (7.0, 16.0), U=2970.000, P=0.007], higher Charlson comorbidity index [median (IQR) 4.0 (2.0, 7.0) vs. 3.0 (1.0, 5.0), U= 3570.000, P=0.036] and higher ratio of breath dysfunction [68.4% (39/57) vs. 48.1% (74/154), χ(2)=6.939, P=0.008] and renal dysfunction [42.1% (24/57) vs. 18.2% (28/154), χ(2)=12.821, P<0.001] were found in surgery-related CCI patients. While SOFA score, Glasgow coma score and other visceral function were not significantly different between surgery-related CCI and non-CCI patients (all P>0.05). NUTRIC score showed that surgery-related CCI patients had higher nutritional risk [43.9% (25/57) vs. 26.6%(41/154), U=5.750, P=0.016] and higher ratio of mechanical ventilation [66.7% (38/57) vs. 52.3% (79/154), χ(2)=3.977, P=0.046] than non-CCI patients. On the survey day, the daily caloric requirements of 50.2% (106/211) of surgery-related ICU patients were calculated according to the standard adult caloric intake index (104.6 to 125.5 kJ·kg(-1)·d(-1), 1 kJ=0.239 kcal), and the daily caloric requirements of 46.4% (98/211) of patients were calculated by physicians according to the severity of the patient's condition. 60.2% (127/211) of nutritional support therapy was enteral nutrition (including a combination of enteral and parenteral nutrition), while the remaining patients received parenteral nutrition (24.6%, 52/211), simple glucose infusion (9.0%, 19/211), or oral diet (6.2%, 13/211). The target calorie of CCI group was 104.6 (87.9, 125.5) kJ·kg(-1)·d(-1), and the actual calorie intake accounted for 0.98 (0.80, 1.00) of the target calory. In the non-CCI group, the target calorie was 104.6 (87.9, 125.5) kJ·kg(-1)·d(-1), and the actual calorie consumed accounted for 0.91 (0.66, 1.00) of the target calorie. There was no statistically significant difference between two groups (P=0.248, P=0.150). Conclusion: The prevalence of CCI and surgery-related CCI in ICU is high, along with severe complications, respiratory and renal dysfunction and mechanical ventilation. Surgical patients admitted to ICU are at high nutritional risk, and active and correct nutritional support is essential for such patients.

Abstract
Objective: To study the effect on immune indexes in children with obstructive sleep apnea hypopnea syndrome (OSAHS) before and after resection of adenoid and/or tonsil. Methods: A total of 100 children with OSAHS due to adenoid hypertrophy were enrolled in Department of Otorhinolaryngology Head and Neck Surgery, the Second Hospital of Dalian Medical University from December 2016 to December 2018. Some cases were complicated with tonsil hypertrophy or chronic tonsillitis. 6 ml of fasting peripheral venous blood were collected from all subjects at the 1st day before surgery, 4th day, 1 month, 3 months and 6 months after surgery to detect lymphoid subsets percentage (CD3(+), CD4(+),CD8(+), CD4/CD8, CD19, NK) and level of immunoglobulin (IgG, IgA, IgM). Grouping: group A was a total of 51 cases with adenoid hypertrophy after Adenoid plasma ablation; group B was a total of 27 cases with adenoid hypertrophy and chronic tonsillitis after plasma ablation of adenoid and tonsil; and group C was a total of 22 cases hypertrophy of adenoid and tonsil after plasma ablation of adenoid and tonsil.In the baseline data, age, gender and other variables were analyzed by anova and chi-square test, repeated measurement anova was used for intra-group and inter-group comparison of observation indicators at different time points after operation, and independent sample t-test was used for comparison between the two groups at observation points 3 months after operation. Results: (1) In group A, the percentage of CD19 lymphocytes before surgery was higher than that at 4th day after surgery, and the difference was statistically significant (21.85±6.20 vs.19.18±5.91, P<0.05). The other immune indexes were not statistically different before and after surgery (P>0.05). (2) In group B, the percentage of CD19 lymphocytes, CD3(+)T lymphocytes, CD8(+)T lymphocytes and the level of IgG at 4th day after surgery were significantly different between those before surgery (all P<0.05). At the 1st month after surgery, the percentage of CD3(+)T lymphocytes, CD8(+)T lymphocytes, CD19 lymphocytes and the level of IgG were significantly different between those before surgery (all P<0.05). The other immune indexes were not statistically different before and after operation (P>0.05). (3) In group C, the percentage of CD19 lymphocytes and the CD3(+)T lymphocytes at 4th day after surgery were significantly different between those before surgery (all P<0.05).In the 1st month after surgery, the percentage of CD8(+)T lymphocytes and CD19 lymphocytes were significantly different between those before surgery (all P<0.05). The other immune indexes were not statistically different before and after operation (P>0.05). (4) Among three groups, the percentage of CD4(+)T lymphocytes, the levels of IgG and IgA before surgery between group A and Group B were statistically significant (all P<0.05). At 4th day after surgery, the percentage of CD4(+)T lymphocytes in group B and C were lower than those in group A, and the differences were statistically significant (32.22±6.14, 32.36±6.87 vs. 36.36±5.19, all P<0.05); the other immune indexes were not statistically different among each group before and after surgery (P>0.05). Conclusions: Resection of adenoid has no significant effect on the immune indexes in children with OSAHS. The children with OSAHS complicated with tonsil problems have immune index disorder before surgery. Surgery has a certain effect on the immune indexes of children with OSAHS in a short period of time, and tends to normal level after one month.

Abstract
We present a search for subsolar mass ultracompact objects in data obtained during Advanced LIGO's second observing run. In contrast to a previous search of Advanced LIGO data from the first observing run, this search includes the effects of component spin on the gravitational waveform. We identify no viable gravitational-wave candidates consistent with subsolar mass ultracompact binaries with at least one component between 0.2 M_{⊙}-1.0 M_{⊙}. We use the null result to constrain the binary merger rate of (0.2 M_{⊙}, 0.2 M_{⊙}) binaries to be less than 3.7×10^{5} Gpc^{-3} yr^{-1} and the binary merger rate of (1.0 M_{⊙}, 1.0 M_{⊙}) binaries to be less than 5.2×10^{3} Gpc^{-3} yr^{-1}. Subsolar mass ultracompact objects are not expected to form via known stellar evolution channels, though it has been suggested that primordial density fluctuations or particle dark matter with cooling mechanisms and/or nuclear interactions could form black holes with subsolar masses. Assuming a particular primordial black hole (PBH) formation model, we constrain a population of merging 0.2 M_{⊙} black holes to account for less than 16% of the dark matter density and a population of merging 1.0 M_{⊙} black holes to account for less than 2% of the dark matter density. We discuss how constraints on the merger rate and dark matter fraction may be extended to arbitrary black hole population models that predict subsolar mass binaries.

Abstract
The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source. This source, for the first time, permits tests of strong-field dynamics of compact binaries in the presence of matter. In this Letter, we place constraints on the dipole radiation and possible deviations from GR in the post-Newtonian coefficients that govern the inspiral regime. Bounds on modified dispersion of gravitational waves are obtained; in combination with information from the observed electromagnetic counterpart we can also constrain effects due to large extra dimensions. Finally, the polarization content of the gravitational wave signal is studied. The results of all tests performed here show good agreement with GR.

Abstract
The Cramér-Rao bound plays a central role in both classical and quantum parameter estimation, but finding the observable and the resulting inversion estimator that saturates this bound remains an open issue for general multi-outcome measurements. Here we consider multi-outcome homodyne detection in a coherent-light Mach-Zehnder interferometer and construct a family of inversion estimators that almost saturate the Cramér-Rao bound over the whole range of phase interval. This provides a clue on constructing optimal inversion estimators for phase estimation and other parameter estimation in any multi-outcome measurement.

Abstract
Objective: To analyze the status of hypertension and isolated systolic hypertension and to investigate the relationship between the prevalence of hypertension and dietary factors among Chinese elderly aged 60 yea and over during 2010-2012. Methods: Using a multi-stage stratified probability proportional to size cluster randomization sampling method during 2010-2012, a total of 14 791 old people aged 60 years old and over were investigated at 150 counties (districts) from 31 provinces (autonomous regions and municipalities) in China. Information on demographic socio-economic status and the physical activities was collected through questionnaires. Blood pressure measurement and physical examination were carried out by standard methods. The 3 days consecutive individual 24 hours dietary investigation was used to calculate food and nutrients intake of the subjects. Multiple logistic regression was used to investigate the possible related dietary factors for the hypertension and isolated systolic hypertension. Results: The prevalence of hypertension among the elderly aged 60 years old and over was 54.6% (95%CI: 52.8%-56.4%), of which isolated systolic hypertension was 24.5% (95%CI: 23.0%-26.1%). Compared with the lowest intake level, the OR (95%CI) of hypertension for higher tuber consumption (≥43.34 g/d) and milk intake (>0 g/d) with were 0.89 (0.83-0.97) and 0.88 (0.81-0.97), respectively. The OR (95%CI) of hypertension for higher dietary potassium (≥1 747.69 mg/d), folate acid (28.42-56.88 μg/d), vitamin B(1)2 (0.22-0.58 μg/d) and vitamin B(2) (0.61-0.81 mg/d) intake were 0.87 (0.77-0.98), 0.89 (0.81-0.98), 0.88 (0.80-0.97) and 0.89 (0.80-0.99). The OR (95%CI) of isolated systolic hypertension for higher tuber (≥43.34 g/d), milk intake (>0 g/d) and higher dietary potassium (≥1 747.69 mg/d), folate acid (≥99.89 μg/d), vitamin B(12) intake (≥1.48 μg/d) were 0.84 (0.75-0.93), 0.85 (0.76-0.95), 0.82 (0.71-0.96), 0.87 (0.76-0.99) and 0.87 (0.77-0.98). Conclusion: There was inverse association between highertuber consumptione, milk consumption, dietary potassium, folate acid, vitamin B(12) intake and elderly hypertensive and isolated systolic hypertension.

Abstract
目的 探讨非老年成人初发急性髓系白血病(AML)患者年龄相关的临床特征、早期治疗反应和预后。 方法 回顾性分析2008年1月至2017年12月收治的18~65岁初发AML(非急性早幼粒细胞白血病)连续病例,分析不同年龄组患者初诊时疾病特征、早期治疗反应、复发和生存,以及相关影响因素。 结果 共收集1 097例患者,男性591例(53.9%),中位年龄42岁。随着年龄的增长,患者WBC显著下降(P=0.003),PLT显著上升(P=0.034),骨髓原始细胞比例显著下降(P=0.021)。SWOG危险度在各年龄组的分布差异无统计学意义(P=0.063)。NPM1阳性伴FLT3-ITD阴性的患者比例随年龄增长显著上升(P<0.001)。多因素分析显示,在总人群中,年龄增加是获得形态学无白血病状态(MLFS)(P=0.053)、完全缓解(CR)(P=0.004)和总生存(OS)(P=0.070)的不利影响因素,但在接受标准诱导治疗的患者中,年龄增加仅与CR相关(P=0.075),而与MLFS和OS无关。 结论 非老年初发AML患者的临床、细胞遗传学和分子学特征随年龄变化而不同。在接受标准诱导治疗的患者中,年龄增加与获得MLFS和OS均无显著相关性。

Constraining the p-Mode-g-Mode Tidal Instability with GW170817. PHYSICAL REVIEW LETTERS 2019; 122:061104. [PMID: 30822067 DOI: 10.1103/physrevlett.122.061104] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Revised: 10/30/2018] [Indexed: 06/09/2023]
Abstract
We analyze the impact of a proposed tidal instability coupling p modes and g modes within neutron stars on GW170817. This nonresonant instability transfers energy from the orbit of the binary to internal modes of the stars, accelerating the gravitational-wave driven inspiral. We model the impact of this instability on the phasing of the gravitational wave signal using three parameters per star: an overall amplitude, a saturation frequency, and a spectral index. Incorporating these additional parameters, we compute the Bayes factor (lnB_{!pg}^{pg}) comparing our p-g model to a standard one. We find that the observed signal is consistent with waveform models that neglect p-g effects, with lnB_{!pg}^{pg}=0.03_{-0.58}^{+0.70} (maximum a posteriori and 90% credible region). By injecting simulated signals that do not include p-g effects and recovering them with the p-g model, we show that there is a ≃50% probability of obtaining similar lnB_{!pg}^{pg} even when p-g effects are absent. We find that the p-g amplitude for 1.4 M_{⊙} neutron stars is constrained to less than a few tenths of the theoretical maximum, with maxima a posteriori near one-tenth this maximum and p-g saturation frequency ∼70 Hz. This suggests that there are less than a few hundred excited modes, assuming they all saturate by wave breaking. For comparison, theoretical upper bounds suggest ≲10^{3} modes saturate by wave breaking. Thus, the measured constraints only rule out extreme values of the p-g parameters. They also imply that the instability dissipates ≲10^{51} erg over the entire inspiral, i.e., less than a few percent of the energy radiated as gravitational waves.

Abstract
We present the first Advanced LIGO and Advanced Virgo search for ultracompact binary systems with component masses between 0.2 M_{⊙}-1.0 M_{⊙} using data taken between September 12, 2015 and January 19, 2016. We find no viable gravitational wave candidates. Our null result constrains the coalescence rate of monochromatic (delta function) distributions of nonspinning (0.2 M_{⊙}, 0.2 M_{⊙}) ultracompact binaries to be less than 1.0×10^{6} Gpc^{-3} yr^{-1} and the coalescence rate of a similar distribution of (1.0 M_{⊙}, 1.0 M_{⊙}) ultracompact binaries to be less than 1.9×10^{4} Gpc^{-3} yr^{-1} (at 90% confidence). Neither black holes nor neutron stars are expected to form below ∼1 M_{⊙} through conventional stellar evolution, though it has been proposed that similarly low mass black holes could be formed primordially through density fluctuations in the early Universe and contribute to the dark matter density. The interpretation of our constraints in the primordial black hole dark matter paradigm is highly model dependent; however, under a particular primordial black hole binary formation scenario we constrain monochromatic primordial black hole populations of 0.2 M_{⊙} to be less than 33% of the total dark matter density and monochromatic populations of 1.0 M_{⊙} to be less than 5% of the dark matter density. The latter strengthens the presently placed bounds from microlensing surveys of massive compact halo objects (MACHOs) provided by the MACHO and EROS Collaborations.
