Abstract
N6-methyladenosine (m6A) is a eukaryotic messenger RNA modification catalyzed by methyltransferase-like 3 (METTL3), which is involved in various developmental and disease processes. However, the connection between the epigenetic modification of m6A and glucose metabolism during osteogenesis is still unclear. Here, we show that interference with METTL3 in dental pulp stem cells (DPSCs) inhibits cell proliferation and osteogenic differentiation. Moreover, transcriptome sequencing and metabolic testing were used to explore the mechanism between glucose metabolism and m6A modification in METTL3-knockdown DPSCs. Methylated RNA immunoprecipitation-quantitative polymerase chain reaction and RNA stability assays were used to determine the target genes of METTL3. Mechanistically, METTL3 directly interacts with ATP citrate lyase (ACLY) and a mitochondrial citrate transporter (SLC25A1) and then further affects the glycolytic pathway. M6A-mediated ACLY and SLC25A1 stability depends on the m6A readers IGF2BP2 and IGF2BP2/3, respectively. Our experiments uncovered the potential molecular mechanism of epigenetic modification in osteogenic differentiation, providing new ideas for the clinical application of stem cells and the intervention of metabolic bone diseases.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2021; 2021:5551568. [PMID: 34630609 PMCID: PMC8494586 DOI: 10.1155/2021/5551568] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/27/2021] [Revised: 09/01/2021] [Accepted: 09/20/2021] [Indexed: 11/18/2022]
Abstract
Background. Oxaliplatin-induced peripheral neuropathy (OIPN) is one of the most common side effects of oxaliplatin, which can cause reduction and cessation of oxaliplatin-based chemotherapy and significantly affect patients' quality of life. However, no drug has got recognition to prevent or treat OIPN. Yiqi-Wenjing-Fang (YWF) is a joint name of Chinese medicine prescriptions with similar effects of tonifying qi and warming meridians, represented by Huangqi Guizhi Wuwu decoction (HGWD) and Danggui Sini decoction (DSD), both from "Treatise on Cold Pathogenic and Miscellaneous Diseases." YWF granules, including HGWD granules and DSD granules, have been, respectively, demonstrated to be effective in preventing OIPN in previous small-sample observations. The purpose of this study is to enlarge the sample size for further evaluation of the preventive efficacy and safety of YWF granules on OIPN. Methods and Analysis. This study is a randomized, double-blind, placebo-controlled, and multicenter clinical trial. 360 postoperative patients with stage IIa-IIIc colorectal cancer will be randomly assigned into placebo-control group, intervention group I, and intervention group II, taking the mimetic granules of YWF as placebo, HGWD granules and DSD granules, respectively. All subjects will receive oxaliplatin-based chemotherapy regimen at the same time. EORTC QLQ-CIPN20 will be used to assess the degree of OIPN as the primary outcome measure. The grades of OIPN, quality of life, chemotherapeutic efficacy, and the number of completed chemotherapy cycles are selected as the secondary outcome measures. Discussion. Based on the condition of no recognized effective drugs in preventing OIPN, evidence-based medical study will be conducted for seeking a breakthrough in the field of Chinese herb medicine. This protocol could provide reliable and systemic research basis about the efficacy of YWF granules and the differentiation of two classical prescriptions of YWF on preventing OIPN objectively. Trial Registration. This study was registered at ClinicalTrials.gov on 26 December 2020 (ID: https://clinicaltrials.gov/ct2/show/NCT04690283).

Abstract
Objective: To investigate the MRI features of hepatic nodular regenerative hyperplasia (NRH) induced by chemotherapy. Methods: The clinical data and MRI of 20 cases with hepatic NRH induced by chemotherapy and confirmed by pathology in Zhongshan Hospital Fudan University from August 2014 to May 2019 were retrospectively analyzed. There were 13 males and 7 females, with an average age of 49.8 ± 9.7 years. Contrast-enhanced MR scan with Gd-DTPA was performed eighteen patients, and two patients underwent contrast-enhanced MR scan with hepatobiliary specific contrast (Gd-EOB-DTPA). The image analysis includes the number, location, size, shape, signal intensity in plain scan and enhancement pattern of lesions. The apparent diffusion coefficient (ADC) values of the lesions and adjacent hepatic parenchyma were measured on the ADC map, and the difference was compared with paired sample t test. Results: A total of 36 lesions in 20 patients were rounded or oval, including 23 (63.9%) lesions in the right lobe, 12 (33.3%) in the left lobe and 1 (2.8%) in the caudate lobe. The average diameter of all lesions was 15.4 ± 6.4 (7.0-37.0) mm. The boundary was clear in 9 (25.0%) lesions and blurred in 27 (75%) lesions. In T1WI, 35 (97.2%) lesions showed slightly hypointensity, and in 1 (2.8%) lesion was iosintensity. All 36 lesions showed slightly hyperintensity in T2WI. 33 (91.7%) lesions showed slightly hyperintensity in DWI, and 3 (8.3%) lesions showed iosintensity. 31 lesions with Gd-DTPA enhanced MR scan were significantly enhanced in the arterial phase and showed slightly high signal intensity in early portal vein phase, late portal vein phase and equilibrium phase. 5 lesions with Gd-EOB-DTPA enhanced MR scan were also significantly enhanced in the arterial phase and showed slightly high signal intensity in early portal vein phase, late portal vein phase and equilibrium phase, then all lesions showed circular high signal intensity in hepatobiliary specific phase. The average ADC value of 29 lesions was (1.471 ± 0.253) × 10(-3) mm(2)/s, and that of adjacent liver parenchyma was (1.460 ± 0.235) ×10(-3) mm(2)/s. There was no significant difference between the two groups (P > 0.05). Conclusion: MR findings of NRH induced by chemotherapy have certain characteristics, and the morphological manifestations, diffusion-weighted imaging, enhanced imaging and hepatobiliary specific phase features of the lesions can help to diagnose the disease.

Abstract
Heteronuclear dipolar coupling is indispensable in revealing vital information related to the molecular structure and dynamics, as well as intermolecular interactions in various solid materials. Although numerous approaches have been developed to selectively reintroduce heteronuclear dipolar coupling under MAS, most of them lack universality and can only be applied to limited spin systems. Herein, we introduce a new and robust technique dubbed phase modulated rotary resonance (PMRR) for reintroducing heteronuclear dipolar couplings while suppressing all other interactions under a broad range of MAS conditions. The standard PMRR requires the radiofrequency (RF) field strength of only twice the MAS frequency, can efficiently recouple the dipolar couplings with a large scaling factor of 0.50, and is robust to experimental imperfections. Moreover, the adjustable window modification of PMRR, dubbed wPMRR, can improve its performance remarkably, making it well suited for the accurate determination of dipolar couplings in various spin systems. The robust performance of such pulse sequences has been verified theoretically and experimentally via model compounds, at different MAS frequencies. The application of the PMRR technique was demonstrated on the H-ZSM-5 zeolite, where the interaction between the Brønsted acidic hydroxyl groups of H-ZSM-5 and the absorbed trimethylphosphine oxide (TMPO) were probed, revealing the detailed configuration of super acid sites.

Abstract
BACKGROUND True thymic hyperplasia (TTH) is characterized as a distinct increase in both size and weight of thymus, which retains normal microscopic and immunohistochemical appearances. Massive true thymic hyperplasia (MTTH) is an extremely rare but significant subtype of TTH in pediatric ages due to its potentially serious consequences. It was reported that the age of cases with MTTH was predominantly between 1 and 15 years, while those before 1 year rarely occurred. By presenting the diagnosis and treatment process of our case as well as reviewing the related literature, we aimed to analyze the clinical characteristics of MTTH for patients younger than 1 year. CASE A 3-month-old male infant was admitted to our department with a chief complaint of gradually increasing polypnea over 9 days, whose preoperative imaging examination showed a large intrathoracic soft tissue shadow predominantly on the right side. The percutaneous fine-needle biopsy guided by ultrasonography was performed to identify its diagnosis. However, proliferating lymphocytes and Hassall`s corpuscles were seen microscopically in the biopsy tissues, which were immunohistochemically positive for CD3, CD19, CD20, CD99, TdT, PCK and Ki67 ( > 90%). Due to the aggravating symptoms, a second operation with total thymectomy was carried out successfully for this infant, which confirmed the diagnosis of TTH again by both morphological study and immunohistochemical staining from the surgical specimen. CONCLUSIONS By reviewing the literature, there were only 10 cases with MTTH reported between 1975 and 2020 for children aged < 1 year of life, together with our present one. In MTTH patient`s sex had an obviously male predominance (70%). Nine out of 10 presented initial symptoms or signs related to respiratory system and 6 patients showed respiratory distress. All patients were successfully treated by surgical thymectomy without any postoperative complications. The prognosis of MTTH was very successful.

Abstract
We report on the first measurement of charm-strange meson D_{s}^{±} production at midrapidity in Au+Au collisions at sqrt[s_{NN}]=200 GeV from the STAR experiment. The yield ratio between strange (D_{s}^{±}) and nonstrange (D^{0}) open-charm mesons is presented and compared to model calculations. A significant enhancement, relative to a pythia simulation of p+p collisions, is observed in the D_{s}^{±}/D^{0} yield ratio in Au+Au collisions over a large range of collision centralities. Model calculations incorporating abundant strange-quark production in the quark-gluon plasma and coalescence hadronization qualitatively reproduce the data. The transverse-momentum integrated yield ratio of D_{s}^{±}/D^{0} at midrapidity is consistent with a prediction from a statistical hadronization model with the parameters constrained by the yields of light and strange hadrons measured at the same collision energy. These results suggest that the coalescence of charm quarks with strange quarks in the quark-gluon plasma plays an important role in D_{s}^{±}-meson production in heavy-ion collisions.

Abstract
Low-cost meat, such as duck, is frequently used to adulterate more expensive foods like lamb or beef in many countries. However, the lack of DNA-based reference materials has limited the quality control and detection of adulterants. Here, we report the development and validation of duck genomic DNA certified reference materials (CRMs) through the detection of the duck interleukin 2 (IL2) gene by digital PCR (dPCR) for the identification of duck meat in food products. The certified value of IL2 in CRMs was 5.78 ± 0.51 × 103 copies/μL with extended uncertainty (coverage factor k = 2) based on IL2 quantification by eight independent collaborating laboratories. Quantification of the mitochondrial gene cytb revealed a concentration of 2.0 × 106 copies/μL, as an information value. The CRMs were also used to determine the limit of detection (LOD) for six commercial testing kits, which confirmed that these kits meet or exceed their claimed sensitivity and are reliable for duck detection.

Abstract
Abstract
Study question
To evaluate the efficiency and accuracy of Raman microspectra in detecting sperm chromosome balance state by DNA content difference.
Summary answer
Raman spectroscopy can identify the difference of X and Y sperm DNA content, but the accuracy still needed to be improved for clinical application.
What is known already
Aneuploid sperm fertilization affects embryo quality and leads to the waste of oocytes in Assisted Reproductive Technology (ART). Raman spectroscopy can identify substances and observe molecular changes through specific spectral patterns with high specificity and has become a new hot spot in ART. Previous research has used this technology to detect embryo culture medium to evaluate the aneuploidy of embryos. The DNA content of X and Y in sperm was different, which may serve as a marker for sperm aneuploidy detection by Raman spectroscopy.
Study design, size, duration
The significant difference in the morphology of the sex chromosomes of X and Y spermatozoa leads to a substantial difference in the DNA content. We perform Raman spectroscopy to identify the spectral differences of the sperms, especially the differences in sperm DNA content. We further verified the accuracy with fluorescence in situ hybridization (FISH).
Participants/materials, setting, methods
Spermatozoa were provided by healthy donors with normal aneuploidy, and analysis parameters met the current World Health Organization (WHO, 2010) standards. Sperm heads were detected by laser confocal Raman spectroscopy and obtained the corresponding spectra. The sperm chromosome information was classified by Standard principal component analysis (PCA) and identified by fluorescence in situ hybridization (FISH). Student’s t-test and Receiver operating characteristic (ROC) curve analysis was performed for further analysis.
Main results and the role of chance
Standard principal component analysis (PCA) after unqualified quality control divided spermatozoa into two groups according to the calculation and calibration results, 22 cases in group A and 31 cases in group B. Then, we conducted frequency distribution histogram statistics on the above data, and the results showed that there were differences in frequency distribution at I785 = 23,750 and Area714 –1162 = 3,250,000. The FISH analysis identified sex chromosomes of 59 spermatozoa, which was not exactly one-to-one correspondence with the results of PCA analysis. Then we further analyzed the sperm of 59 cases by statistical analysis. The results showed that there were significant differences between X sperm (n = 39) and Y sperm (n = 20) at 714–1162 cm–1 and 785 (P < 0.05). ROC curve analysis was used to evaluate the sensitivity of correlation between sperm DNA content and Raman spectra. The results showed that the corresponding thresholds of I785 = 24,986.5 and Area714–1162 cm–1 = 3,748,990 were the best for distinguishing the two kinds of sperm. When the sperm’s peak value of 785 or 714–1162cm–1 exceeds the above thresholds, X-sperm’s possibility greatly increased. The AUC of the ROC curve in both cases was 0.662 and 0.696, respectively.
Limitations, reasons for caution
Current Raman spectroscopy requires spermatozoa elution and fixation, which damage the sperms. Furthermore, current Raman spectral data are not obtained from the whole sperm head, limiting the accuracy of this technique.
Wider implications of the findings: Our results indicated that Raman spectroscopy had potential application value for sperm aneuploidy detection and could be used as a noninvasive selector for normal haploid sperms in the ART.

Abstract
Abstract
Study question
To study the relationship between mitochondrial DNA copy number of cumulus granulosa cells (CGCs-mtDNA) and the quality of early embryos.
Summary answer
CGCs-mtDNA was related to the symmetry of cleavage. However, CGCs-mtDNA was not associated with fertilization, blastocysts quality, or blastocysts euploidy.
What is known already
The potential of early embryonic development mainly depends on the quality of oocytes to a large extent. Mitochondria of CGCs are directly involved in the establishment of oocytes capacitation during oocytes maturation and development.
Study design, size, duration
This is a retrospective study from December 2018 to January 2019, involving a total of 283 CGCs surrounding Metaphase II oocytes from 49 patients who underwent preimplantation genetic testing for aneuploidy (PGT-A) at the Reproductive and Genetic Hospital of CITIC-Xiangya.
Participants/materials, setting, methods
We used the TaqMan probes to quantitatively detect mitochondrial DNA copy number of per CGCs by quantitative PCR in mitochondrial genes (MT-ND1 and MT-CO1) and a nuclear gene (β-globin). Besides, according to the nature of the dependent variable, the binary logistic regression model and the logistic regression analysis model of ordered multi-classification were used for multivariate statistical analysis.
Main results and the role of chance
The CGCs-mtDNA corresponding to fertilized eggs was not different from that of unfertilized eggs in MT-ND1 gene and MT-CO1 gene (MT-ND1: fertilized vs. unfertilized, 600±337 vs. 604±367, P = 0.593; MT-CO1: fertilized vs. unfertilized, 1336±531 vs. 1329±478, P = 0.938). Interestingly, we found that the CGCs-mtDNA of D3 embryos with good quality was statistically higher than that of D3 embryos with fair or poor quality for MT-ND1 gene and MT-CO1 gene (MT-ND1: good quality vs. fair/poor quality, 803±627 vs. 587±307, P = 0.028; MT-CO1: good quality vs. fair/poor quality, 1682±554 vs. 1374±702, P = 0.025). Moreover, the CGCs-mtDNA corresponding to D3 embryos with even cleavage was higher than that of D3 embryos with uneven cleavage (MT-ND1: even cleavage vs. uneven cleavage, 803±627 vs. 590±309, P = 0.036; MT-CO1: even cleavage vs. uneven cleavage, 1562±552 vs. 1316±525, P = 0.037). Besides, we investigated the difference among the CGCs-mtDNA in blastocysts with the good quality, blastocysts with fair or poor quality, and the developmental blocked embryos before the blastocyst stage. But we didn’t found any difference among the above three groups (MT-ND1: P = 0.531; MT-CO1: P = 0.609). In the study of the relationship between CGCs-mtDNA and blastocysts euploidy, we got similar results (MT-ND1: P = 0.602; MT-CO1: P = 0.570).
Limitations, reasons for caution
The sample size of this study was relatively small.
Wider implications of the findings: Although the sample size of this study is limited, our results indicated the importance of mitochondria in CGCs in early embryo development, especially in the first three days. The investigation of mitochondrial function in CGCs may shed light on the mechanism of CGCs-oocyte crosstalk.

Abstract
The Breit-Wheeler process which produces matter and antimatter from photon collisions is experimentally investigated through the observation of 6085 exclusive electron-positron pairs in ultraperipheral Au+Au collisions at sqrt[s_{NN}]=200 GeV. The measurements reveal a large fourth-order angular modulation of cos4Δϕ=(16.8±2.5)% and smooth invariant mass distribution absent of vector mesons (ϕ, ω, and ρ) at the experimental limit of ≤0.2% of the observed yields. The differential cross section as a function of e^{+}e^{-} pair transverse momentum P_{⊥} peaks at low value with sqrt[⟨P_{⊥}^{2}⟩]=38.1±0.9 MeV and displays a significant centrality dependence. These features are consistent with QED calculations for the collision of linearly polarized photons quantized from the extremely strong electromagnetic fields generated by the highly charged Au nuclei at ultrarelativistic speed. The experimental results have implications for vacuum birefringence and for mapping the magnetic field which is important for emergent QCD phenomena.

Abstract
The incidence and mortality of lung cancer ranked the first in China. China had 787, 000 new cases of lung cancer in 2015, and a majority of these patients with advanced lung cancer. With the development and popularization of high-resolution computed tomography, more and more early-stage lung adenocarcinomas are found in screening. The imaging finding of early-stage lung adenocarcinomas often manifests as part solid nodule (PSN) containing ground glass opacity (GGO). Although the imaging manifestation of the nodules can't accurately predict the pathologic type of nodules, the parts of solid nodule and GGO still have some pathologic indications, and the prognostic evaluation effect of the maximum diameter of PSN is superior to that of the whole nodule. With the development of the molecular radiography and molecular pathology, the relationship of imaging manifestation of the PSN and metastasis were focused on. Some PSNs with special nature are more active and rapidly progressed than the pure GGOs. While compared to the pure solid nodules, the aggressiveness of PSNs are insufficient, with lower metastatic rates of lymph node and better prognoses. Currently, international acknowledge recommends to take active intervention measure for PSNs which are highly suspected to be malignant. We focus on the diagnosis and treatment of PSNs, systemically depict their staging, follow-up, surgical treatment, gene detection and immunotherapy.

Abstract
Importance Propranolol has become the first-line therapy for problematic infantile hemangiomas (IHs) that require systemic therapy. However, different adverse events have been reported during propranolol treatment. The positive efficacy and safety of atenolol raise the question of whether it could be used as a promising therapy for IH. Objective To compare the efficacy and safety of propranolol vs atenolol in infants (between age 5 and 20 weeks) with problematic IHs who required systemic therapy. Design, Setting, and Participants This was a prospective, multicenter, randomized, controlled, open-label clinical trial conducted in collaboration among 6 separate investigation sites in China from February 1, 2015, to December 31, 2018. A total of 377 patients met the criteria for inclusion and were randomized to the propranolol (190 [50.4%]) and atenolol (187 [49.6%]) groups. Data were analyzed in June 2020. Interventions Participants were randomized to receive either propranolol or atenolol for at least 6 months. They completed efficacy assessments at 2 years after the initial treatment. Main Outcomes and Measures The primary outcome was any response or nonresponse at 6 months. The key secondary outcome was changes in the hemangioma activity score. Results Of 377 participants, 287 (76.1%) were female, and the mean (SD) age was 10.2 (4.0) weeks in the propranolol group and 9.8 (4.1) weeks in the atenolol group. After 6 months of treatment, in the propranolol and atenolol groups, the overall response rates were 93.7% and 92.5%, respectively (difference, 1.2%; 95% CI, -4.1% to 6.6%). At 1 and 4 weeks after treatment, and thereafter, the hemangioma activity score in the atenolol group aligned with the propranolol group (odds ratio, 1.034; 95% CI, 0.886-1.206). No differences between the propranolol group and atenolol group were observed in successful initial responses, quality of life scores, complete ulceration healing times, or the rebound rate. Both groups presented a similar percentage of complete/nearly complete responses at 2 years (82.1% vs 79.7%; difference, 2.4%; 95% CI, -5.9% to 10.7%). Adverse events were more common in the propranolol group (70.0% vs 44.4%; difference, 25.6%; 95% CI, 15.7%-34.8%), but the frequency of severe adverse events did not differ meaningfully between the groups. Conclusions and Relevance In this randomized clinical trial, when compared with propranolol, atenolol had similar efficacy and fewer adverse events in the treatment of infants with problematic IHs. The results suggest that oral atenolol can be used as an alternative treatment option for patients with IH who require systemic therapy. Trial Registration ClinicalTrial.gov Identifier: NCT02342275.

Abstract
BACKGROUND Kaposiform lymphangiomatosis (KLA), which is a new subtype of generalized lymphatic anomaly, is a rare disease with a poor prognosis. Currently, there is no standard treatment due to the poor understanding of KLA. Sirolimus, which is an inhibitor of mammalian target of rapamycin, has been shown to have promising potential in the treatment of complicated vascular anomalies. The aim of this study was to introduce the use of sirolimus for the treatment of KLA and to highlight the challenges of managing this refractory disease. RESULTS We reported seven patients with KLA who received sirolimus therapy in our center. Combined with previously reported cases, 58.3% achieved a partial response, 25.0% had stable disease, and 16.7% experienced disease progression. No severe sirolimus-related adverse events occurred during treatment. CONCLUSIONS This study suggests that sirolimus is currently an option for the treatment of KLA, and it is hoped that more specific therapies will be developed in the future. Rapid advances in basic science and clinical practice may facilitate the development of important new treatments for KLA.

Abstract
BACKGROUND Ribociclib plus fulvestrant demonstrated significant progression-free survival (PFS) and overall survival (OS) benefits in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative (HR+/HER2-) advanced breast cancer (ABC). Here we present a new landmark in survival follow-up for a phase III cyclin-dependent kinases 4 and 6 inhibitor clinical trial in patients with ABC (median, 56.3 months). PATIENTS AND METHODS This phase III, randomized, double-blind, placebo-controlled trial was conducted at 174 sites (30 countries). Patients were men and postmenopausal women (age ≥18 years) with histologically/cytologically confirmed HR+/HER2- ABC. Patients could have received ≤1 line of endocrine therapy (ET) but no chemotherapy for ABC. Patients, assigned 2:1, were stratified by the presence/absence of liver/lung metastases and previous ET. Patients received intramuscular fulvestrant (500 mg, day 1 of each 28-day cycle plus day 15 of cycle 1) with oral ribociclib (600 mg/day, 3 weeks on, 1 week off) or placebo. Efficacy analyses were by intention to treat. Safety was assessed in patients receiving ≥1 dose study treatment. OS was a secondary endpoint. MONALEESA-3 is registered with ClinicalTrials.gov (NCT02422615; no longer enrolling). RESULTS Between 18 June 2015 and 10 June 2016, 726 patients were randomly assigned (484, ribociclib; 242, placebo). At data cut-off (30 October 2020), median OS (mOS) was 53.7 months (ribociclib) versus 41.5 months (placebo) [hazard ratio (HR), 0.73; 95% confidence interval (CI) 0.59-0.90]. Subgroup analyses were consistent with overall population. In the first-line setting, most patients in the ribociclib arm (∼60%) lived longer than median follow-up; mOS was 51.8 months in the placebo arm (HR, 0.64; 95% CI 0.46-0.88). In the second-line setting, mOS was 39.7 months (ribociclib) versus 33.7 months (placebo) (HR, 0.78; 95% CI 0.59-1.04). No apparent drug-drug interaction between ribociclib and fulvestrant or new safety signals were observed. CONCLUSIONS This analysis reported extended OS follow-up in MONALEESA-3. mOS was ∼12 months longer in patients with HR+/HER2- ABC treated with ribociclib plus fulvestrant compared with fulvestrant monotherapy.

Abstract
OBJECTIVE Complicated vascular anomalies (VAs) can be intractable and uncontrollable using conventional treatment and can result in lethal outcomes. We undertook a prospective, multicenter phase II trial to evaluate the efficacy and safety of sirolimus in pediatric patients with complicated VAs. METHODS Eligible patients were required to be aged 0 to 14 years and to have a complicated VA. The patients were treated with daily oral sirolimus for 12 months. The primary endpoint was the response, which was measured using sequential volumetric magnetic resonance imaging. The secondary endpoints were the disease severity score and quality of life. RESULTS Of 126 patients enrolled on an intention-to-treat basis, 98 (77.8%) had had an objective response to sirolimus, with a ≥20% decrease in lesion volume. Compared with those with arteriovenous malformations, the response rates were higher (>80%) for patients with common lymphatic malformations, venous malformations, kaposiform hemangioendothelioma, and combined malformations with a prominent venous and/or lymphatic component (P < .05). Improvements in the disease severity score and quality of life were obtained in 83.3% and 79.4% of patients, respectively. The most common adverse event was mucositis in 47 patients. More serious adverse events included reversible grade 4 pneumonitis in 3 patients and grade 4 upper respiratory infection in 1 patient. All these adverse events were considered at least possibly related to the treatment. CONCLUSIONS Sirolimus is an apparently effective option for pediatric patients with various types of complicated VAs. Close monitoring of possible adverse events is required. The results from the present trial are the basis for future prospective studies using new therapeutic approaches.

Abstract
Microorganisms have been known to coexist in various parts of human body including the gut. The interactions between microbes and the surrounding tissues of the host are critical for fine fettle of the gut. The incidence of such microorganisms tends to vary among specific type of cancer affected individuals. Such microbial communities of specific tumor sites in cancer affected individuals could plausibly be used as prognostic and/or diagnostic markers for tumors associated with that specific site. Microorganisms of intestinal and non-intestinal origins including Helicobacter pylori can target several organs, act as carcinogens and promote cancer. It is interesting to note that diets causing inflammation can also increase the cancer risk. Yet, dietary supplementation with prebiotics and probiotics can reduce the incidence of cancer. Therefore, both diet and microbial community of the gut have dual roles of prevention and oncogenesis. Hence, this review intends to summarize certain important details related to gut microbiome and cancer.
