Gut microbiota, a potential cause of higher insulin sensitivity in children with Prader-Willi syndrome.

PURPOSE: Obesity is the main driving factor for comorbidities in Prader-Willi syndrome (PWS) patients due to overeating behaviors. The gut microbiota has been implicated in the etiology of obesity and associated comorbidities. The purpose of the present study was to characterize the fecal microbiota in Chinese patients with PWS and compare it to that of patients with obesity as well as healthy controls. METHODS: We conducted a cross-sectional study with 35 PWS patients (PWS), 35 patients with obesity (OB), and 35 healthy controls (HC). Metagenomic sequencing was performed in stool samples. RESULTS: The composition of the fecal microbiota in PWS patients differed from that of participants in the OB and HC groups. It was characterized by increased Akkermansia Eubacterium, Eubacterium rectale, and Roseburia intestinalis and decreased Parabacteroides and Phascolarctobacterium. Additionally, the homeostatic model assessment of insulin resistance (HOMA-IR) was lower in PWS patients than in patients with obesity. Spearman rank correlation analysis showed that Achromobacter, Acidiphilium, Xylophilus, and Frisingicoccus were significantly negatively correlated with HOMA-IR. CONCLUSION: The composition of the gut microbiota in Chinese PWS patients differed from that in patients with obesity, which might contribute to higher insulin sensitivity in PWS patients.

[A prospective observational study on functional outcomes and condition-specific quality of life after intersphincteric resection for low rectal cancer].

Objective: To investigate functional outcomes and condition-specific quality-of-life (CSQoL) after intersphincteric resection (ISR) in patients with low rectal cancer using traditional and exploratory questionnaires. Methods: A prospective observational study was conducted in the Characteristic Medical Center of the People's Liberation Army Rocket Force. Patients with low rectal cancer who underwent ISR with ileostomy reversal from May 2020 to April 2023 were enrolled. An electronic self-assessment survey was sent to enrolled patients at 3 to 6, 12, and 24 to 36 months after reversal, and differences in functional and CSQoL results between the 3 groups were analyzed with generalized estimation equations. Functional outcomes were determined by the Wexner incontinence score (WIS) and the low anterior resection syndrome (LARS) score. In line with the five frequency responses ranging from never (score 0) to always (score 4) defined by the WIS, an exploratory survey was used to measure the severity of 16 LARS-specific variables confirmed by the latest international Delphi consensus. Furthermore, CSQoL was evaluated using the fecal incontinence quality-of-life scale (FIQL) and the visual analog scale (VAS). Results: A total of 90 patients were enrolled in the study. There were 64 males and 26 females, aged (58.6±10.4) years (range: 28 to 79 years). The median distance from the distal tumor margin to the anal verge(M(IQR)) was 3.0 (1.5) cm (range: 1.0 to 5.0 cm). There were 55 patients who completed the questionnaires at 3 to 6 months, 59 patients at 12 months, and 40 patients at 24 to 36 months of follow-up, respectively. The summary score of FIQL and VAS improved significantly after reversal (2.33±0.69 vs. 2.40±0.66 vs. 2.79±0.76, χ2=11.703,P=0.003; 5.31±1.65 vs. 5.61±1.90 vs. 6.58±1.92, χ2=12.781,P=0.002), but the differences in the WIS and LARS score did not reach statistical significance (both P>0.05). The survey responses for the LARS-specific variables indicated that "emptying difficulties" and "dissatisfaction with the bowels" were the most frequent symptom and consequence after ISR, respectively. The exploratory severity score for LARS improved significantly among the 3 time periods(34 (14) vs. 31 (13) vs. 23 (17), χ2=13.952,P=0.001). Furthermore, the FIQL summary score was strongly correlated with the LARS severity score (rs=-0.72, P<0.01). Conclusions: Although a high prevalence of LARS may persist for years, patients reported an improvement in CSQoL and functional outcomes after ISR. The highest priorities recommended by the international consensus might provide better assessments the severity of LARS.

[Clinical characteristics of patients referred to cardio-oncology clinic].

To explore characteristics of outpatients in a single cardio-oncology clinic, patients visiting cardio-oncology clinic of Fuwai Hospital CAMS&PUMC (Beijing, China) from January 2020 to December 2021 were analyzed retrospectively. In total, 330 patients were included, the median age (Q1, Q3) was 58(46, 66) years, and there were 192 females (58.2%). The purposes for visit included an evaluation and treatment of cardiovascular adverse reactions (n=247, 74.8%), pre-antitumor therapy assessment (n=51, 15.5%), and management of primary or metastatic cardiac tumors (n=32, 9.7%). For patients with cardiovascular adverse reactions, the most common tumor type was breast cancer (n=88, 29.5%), followed by gastrointestinal cancer (n=70, 23.5%), and hematological cancers (n=62, 20.8%). Among them, 236 cases (95.5%) had received antitumor drugs in the past; 38 cases (15.4%) had a history of chest radiotherapy; some cases were complicated with hypertension (n=69, 23.2%) and/or hyperlipidemia (n=69, 23.2%); 42 cases (14.1%) had a history of coronary heart disease; and 16 cases (5.4%) were complicated with atrial fibrillation or flutter. Among 32 patients with cardiac tumors, 11 cases (34.4%) had primary malignant tumors; 6 cases (18.8%) had benign tumors; 2 cases (6.3%) had metastatic tumors; and 13 (40.6%) had unknown pathological types. This study explores the epidemiology of cardio-oncology in China and provides clinical insights for the future development of cardio-oncology. In the future, it is still necessary to study the benefits of cardio-oncology clinics and develop standardized indicators to evaluate their benefits.

Fano-like Resonance due to Interference with Distant Transitions.

Narrow optical resonances of atoms or molecules have immense significance in various precision measurements, such as testing fundamental physics and the generation of primary frequency standards. In these studies, accurate transition centers derived from fitting the measured spectra are demanded, which critically rely on the knowledge of spectral line profiles. Here, we propose a new mechanism of Fano-like resonance induced by distant discrete levels and experimentally verify it with Doppler-free spectroscopy of vibration-rotational transitions of CO_{2}. The observed spectrum has an asymmetric profile and its amplitude increases quadratically with the probe laser power. Our results facilitate a broad range of topics based on narrow transitions.

Experimental Simulation of Open Quantum System Dynamics via Trotterization.

Digital quantum simulators provide a diversified tool for solving the evolution of quantum systems with complicated Hamiltonians and hold great potential for a wide range of applications. Although much attention is paid to the unitary evolution of closed quantum systems, dissipation and noise are vital in understanding the dynamics of practical quantum systems. In this work, we experimentally demonstrate a digital simulation of an open quantum system in a controllable Markovian environment with the assistance of a single ancillary qubit. By Trotterizing the quantum Liouvillians, the continuous evolution of an open quantum system is effectively realized, and its application in error mitigation is demonstrated by adjusting the simulated noise intensities. High-order Trotter for open quantum dynamics is also experimentally investigated and shows higher accuracy. Our results represent a significant step toward hardware-efficient simulation of open quantum systems and error mitigation in quantum algorithms in noisy intermediate-scale quantum systems.

High-Efficiency Arbitrary Quantum Operation on a High-Dimensional Quantum System.

The ability to manipulate quantum systems lies at the heart of the development of quantum technology. The ultimate goal of quantum control is to realize arbitrary quantum operations (AQUOs) for all possible open quantum system dynamics. However, the demanding extra physical resources impose great obstacles. Here, we experimentally demonstrate a universal approach of AQUO on a photonic qudit with the minimum physical resource of a two-level ancilla and a log_{2}d-scale circuit depth for a d-dimensional system. The AQUO is then applied in a quantum trajectory simulation for quantum subspace stabilization and quantum Zeno dynamics, as well as incoherent manipulation and generalized measurements of the qudit. Therefore, the demonstrated AQUO for complete quantum control would play an indispensable role in quantum information science.

[Clinical characteristics of hypertrophic cardiomyopathy and restricted cardiomyopathy patients complicating with intracardiac thrombosis].

Objective: To investigate the clinical characteristics of patients with hypertrophic cardiomyopathy (HCM) and restrictive cardiomyopathy (RCM) complicating with intracardiac thrombosis. Methods: This is a retrospective observational study. Consecutive patients diagnosed with HCM or RCM and complicated with intracardiac thrombosis (including left and right atrium or ventricular thrombosis), who were admitted to the Heart Failure Care Unit of Fuwai Hospital, Chinese Academy of Medical Sciences, from September 2008 to September 2018, were enrolled in this study. Patients with myocardial infarction were excluded. The general clinical data of the enrolled patients, including demographic data, major complications, laboratory indicators, echocardiographic indicators, drug application and distribution of intracardiac thrombosis, were collected from electronic medical record system and analyzed. Results: A total of 98 patients were enrolled in this study, including 52 patients (53.1%) with HCM and 46 patients (46.9%) with RCM. The most common comorbidity was atrial fibrillation/flutter: 40 patients (76.9%) in HCM group and 36 patients (78.3%) in RCM group. Majority of patients received oral anticoagulants treatment: 43 patients (82.7%) in HCM group and 35 patients (76.1%) in RCM group. Intracardiac thrombosis was mainly located in the left atrium in both HCM group (39 cases (75.0%)) and RCM group (32 cases (69.6%)). Thrombosis was found in ≥ 2 chambers in 7 patients (7.1%). Rate of left atrial thrombosis was the highest (81.6% (62/76)) in HCM and RCM patients complicating with atrial fibrillation/flutter. Intra-aneurysmal thrombosis occurred in 4 out of 5 patients complicated with apical left ventricular aneurysm. The rate of left ventricular thrombosis in patients with left ventricular ejection fraction≥50% was 7.4% (4/54), which was significantly lower than that in patients with left ventricular ejection fraction<50% (34.5%(10/29)) (P<0.01). Conclusion: There are certain distribution characteristics of HCM and RCM patients with intracardiac thrombosis, and the left atrium is the most common site of thrombosis, more attention should be paid in HCM and RCM patients on the diagnosis and treatment of intracardiac thrombosis.

[Effects of parental rearing patterns and their consistency on the emotional and behavioral problems of preschool children].

Objective: To explore the effect of parental rearing patterns and their consistency on the emotional and behavioral problems of preschool children. Methods: From October to November 2017, 27 987 children aged 3 to 6 years old from 109 kindergartens in 11 cities of Hubei, Anhui and Jiangsu Provinces were selected by using the cluster sampling method. A total of 27 200 valid questionnaires which were completed by subjects' parents were collected. The emotional and behavioral problems of preschool children were collected by "strengths and difficulties questionnaire" and the parental rearing patterns were evaluated by the "Parental Behavior Scale". The differences in emotional and behavioral abnormality rates of preschool children with different characteristics were analyzed; with emotional and behavioral problems as dependent variables and parental support/participation and compulsion/hostility as independent variables, the multivariate logistic regression model was used to analyze the effect of parental rearing patterns and their consistency on the emotional and behavioral problems of preschool children. Results: The age of children was (4.35±0.96) years old, and 51.4% of children were 13 975 males. There were 24 634 (90.6%) urban children and 17 916 (65.9%) only children. Both parents with strong support/participation accounted for 14.9%, and those with poor support/participation accounted for 11.9%; both parents with strong compulsion/hostility accounted for 15.2%, and those with low compulsion/hostility accounted for 11.3%. The rates of emotional symptoms, conduct behavior, hyperactive behavior, peer interaction, total difficulty score, and abnormal prosocial behavior of preschool children were 9.5%, 9.5%, 18.2%, 24.5%, 11.2%, and 10.2%, respectively. The multivariate logistic regression model analysis showed that after adjusting for gender, only child, living area, family economic status, mother's age and education level, father's education level, and other factors, compared with fathers/mothers with strong support/participation and low compulsion/hostility and parents with strong support/participation and low compulsion/hostility, preschool children who had fathers/mothers with poor support/participation and strong compulsion/hostility or parents with poor support/participation and strong compulsion/hostility were more likely to have emotional symptoms, conduct behavior, hyperactive behavior, peer interaction, total difficulty score, and abnormal prosocial behavior (P<0.05). Conclusions: Parental rearing patterns and their consistency are related to the emotional and behavioral problems of preschool children.

[Efficacy evaluation of one-stage revision combined with intra-articular injection of antifungal agents in the treatment of chronic periprosthetic fungal infection].

Objective: To investigate the clinical effect of one-stage revision combined with intra-articular injection of antifungal agents in the treatment of chronic periprosthetic fungal infection. Methods: A retrospective analysis of 11 patients(4 hips, 7 knees) admitted with chronic periprosthetic fungal infection at Department of Orthopaedics, First Affiliated Hospital of Xinjiang Medical University from January 2004 to April 2016.There were males and females with an age of 67 years (range:47-77 years). Each patient underwent single-stage revision including aggressive soft-tissue debridement. Liquid samples and tissue samples were immediately sent to the microbiology laboratory for drug sensitivity testing and histological analysis. Removed the infected components and cement thoroughly, pouring powdered vancomycin into the medullary cavity and direct intra-articular injection of fungussensitive antibiotics. The patients with infected hips received an uncemented prosthesis and 0.5 g of gentamicin loaded commercial cement was received by the patients with infected knee.After that, a new prosthesis was implanted.Long-term combination therapy of antibacterial agents and antifungal agents were given after operation. Recurrence of infection and clinical outcomes were evaluated. The follow-up period was 5 years (range: 2-12 years). Results: One patient died of acute heart failure on the eighth postoperative day.Three infection cases were recurred.Eight cases had satisfactory outcomes and required no additional surgical or medical treatment for recurrence of infection. The Harris hip score assessed preoperatively and at latest follow-up was increased from 39.25±5.12 to 79.50±4.79, the difference was statistically significant (t=-11.356, P=0.001).The Hospital for Special Surgery knee score was improved from preoperative 46.25±5.61 to final follow-up 80.50±5.06, and the difference was statistically significant (t=-9.930, P=0.002). Conclusion: Treatment of chronic fungal periprosthetic joint infection with single-stage revision can be fairly effective for achieving acceptable functional outcomes.

MicroRNA-548-3p and MicroRNA-576-5p enhance the migration and invasion of esophageal squamous cell carcinoma cells via NRIP1 down-regulation.

Nuclear receptor interacting protein (NRIP1), also known as RIP140, is a transcriptional co-regulator required for the maintenance of energy homeostasis and ovulation. Although several studies have identified roles for NRIP1 in various cell processes, the biological functions of NRIP1 in esophageal squamous cell carcinoma (ESCC) remain unknown. Herein, we demonstrate that NRIP1 inhibits the migration and invasion of ESCC cells. Further mechanistic studies revealed that NRIP1 is directly targeted by miR-548-3p and miR-576-5p. We then identified that miR-548-3p and miR-576-5p regulate the migration and invasion of ESCC cells by inhibiting NRIP1 expression. Interestingly, the expression of miR-548-3p and miR-576-5p in ESCC cell lines and ESCC tissues is up-regulated and NRIP1 is down-regulated relative to controls. A statistically significant inverse association was found between the expression levels of miR-548-3p/miR-576-5p and NRIP1. These combined results reveal novel functions for miR-548-3p, miR-576-5p, and NRIP1 in regulating ESCC cell migration and invasion which are important functions for the metastatic process in esophageal cancer.

Optic Nerve Crush Induces Changes of Hydrogen Sulfide Synthases Expression in the Rat Retina.

OBJECTIVES: To investigate the expression changes of the hydrogen sulfide synthases cystathionine γ-lyase （CSE）, cystathionine ß-synthase （CBS）, and 3-mercaptopyruvate sulfurtransferase （3-MST）, after optic nerve crush （ONC） in rat the retina. METHODS: The rat model of ONC was established. Rats were divided into normal control, ONC, and sham control groups. Histopathologic changes in retina, the number of retinal ganglion cells （RGC） and retinal thickness of inner part （RTIP） were measured. The changes of CSE, CBS and 3-MST mRNA expression were detected with quantitative real-time PCR. RESULTS: The retinal histostructure was normal in normal controls and with minor changes in sham controls, respectively. Compared with sham group, significant retina damages were found in the ONC group： a time-dependent reduction of RGC number and RTIP. Expressions of CSE, CBS and 3-MST mRNA in rat retina were detected in normal control. Compared with normal controls, the expressions of CSE, CBS and 3-MST mRNA did not show any significant changes in the sham controls. Compared with sham controls, CBS mRNA expressions showed a time-dependent increase at 3 d, 7 d and 14 d after crush in the ONC group; CSE mRNA expressions increased to the peak at 3 d and then slightly reduced at 14 d after crush; 3-MST mRNA expressions showed the trend of increase at 3 d and 7 d and then enhanced remarkably at 14 d after crush. CONCLUSIONS: Hydrogen sulfide synthases CSE, CBS and 3-MST expressions were up-regulated in rat retina following ONC, which may cause an increase in local endogenous hydrogen sulfide production in the retina and a compensatory protective effect.

[Analysis of influencing factors of heart rate deceleration capacity in patients with dilated cardiomyopathy].

Objective: To investigate the determinants affecting the heart rate deceleration capacity (DC) in patients with dilated cardiomyopathy (DCM). Methods: One hundred patients with DCM (DCM group) and 202 healthy subjects (control group) were respectively enrolled. Echocardiography and 24 hours electrocardiogram were performed in all subjects. DC value was compared between the two groups. Multiple regression analysis was made to evaluate the related determinants of DC ((age, sex, echocardiographic parameters including the left atrial diameter (LAD) and left ventricular ejection fraction (LVEF)). Results: (1) DC value was significantly lower in DCM group than in control group( (4.40±2.03) ms vs. (7.30±1.81) ms, P<0.01), prevalence of DC value≤4.5 ms was significantly higher in DCM group than in control group (62% vs. 6%, P<0.01). (2) DC value in the DCM group decreased in proportion to increasing LAD dimension, DC value was (5.60±2.04) ms, (4.50±2.07) ms and (3.60±1.62) ms (P<0.05) in DCM patients with LAD≤40 mm, 40 mm50 mm, respectively. (3) DC value in the DCM group was negatively related to the LAD (r=-0.366, P<0.01), positively related to the LVEF (r= 0.241, P<0.01), but not related with age and sex. Multiple factors regression analysis showed that increased LAD was related to the reduced DC values independtly. Conclusion: DC value of the patients in the DCM group is decreased, which indicate the decrease of the vagus nerve tension, and increased LAD is related to the reduced DC value independtly in DCM patients.

Genome-wide gene expression and DNA methylation differences in abnormally cloned and normally natural mating piglets.

Many studies have proved that DNA methylation can regulate gene expression and further affect skeletal muscle growth and development of pig, whereas the mechanisms of how DNA methylation or gene expression alteration ultimately lead to phenotypical differences between the cloned and natural mating pigs remain elusive. This study aimed to investigate genome-wide gene expression and DNA methylation differences between abnormally cloned and normally natural mating piglets and identify molecular markers related to skeletal muscle growth and development in pig. The DNA methylation and genome-wide gene expression in the two groups of piglets were analysed through methylated DNA immunoprecipitation binding high-throughput sequencing and RNA sequencing respectively. We detected 1493 differentially expressed genes between the two groups, of which 382 genes were also differentially methylated. The results of the integrative analysis between DNA methylation and gene expression revealed that the DNA methylation levels showed a significantly negative and monotonic correlation with gene expression levels around the transcription start site of genes. By contrast, no notable monotonic correlation was observed in other regions. Furthermore, we identified some interesting genes and signalling pathways (e.g. myosin, heavy chain 7 and mammalian target of rapamycin) which possibly play essential roles in skeletal muscle growth and development. The results of this study provide insights into the relationship of DNA methylation with gene expression in newborn piglets and into the mechanisms in abnormally cloned animals through somatic cell nuclear transfer.

Fine mapping and characterization of the or gene in Chinese cabbage (Brassica rapa L. ssp pekinensis).

Orange inner leaves/heads is a qualitative trait in Chinese cabbage that is controlled by a single recessive gene. Orange head Chinese cabbage contain more carotenoids than its white head counterpart; hence, this trait is of interest to both researchers and consumers. In this study, we selected the orange head Chinese cabbage line 07A163 and the white head Chinese cabbage line Chiifu as test materials. We localized the target gene controlling the orange head trait to the A09 linkage group, with a physical distance of approximately 19.9 kb between the two markers, syau26 and syau28. This region contains six candidate genes, including Bra031539, which was predicted to encode CRTISO, a carotenoid isomerase specifically required for carotenoid biosynthesis. A comparison of the nucleic acid sequences of the two test materials revealed 88 and 7-bp deletions and 88 SNPs in the promoter region of Bra031539 in line 07A163, along with a 6-bp deletion in the first exon and early termination at the 3' end of this gene. BLAST analysis revealed that 22 amino acids were altered and 17 amino acids were lost in Bra031539 in the orange head line 07A163. We developed the BrPro1 molecular marker in the promoter region of Bra031539 that can be used for early identification of orange head materials, thereby accelerating the breeding process of orange head Chinese cabbage.

There is no significant difference of the change of ODI among three groups (P>0.05). mis-TLIF group and mini-open TLIF group was superior to open TLIF group in VAS of the second day postoperative [(3.2±1.6) scale, (3.4±1.5) scale vs(5.8±1.4)scale](P<0.05). Conclusion: mis-TLIF, mini-open TLIF and open TLIF can all get satisfactory clinical outcomes in the treatment of single segment lumbar degenerative disease.mis-TLIF and mini-open TLIF was superior to open TLIF in blood loss, early postoperative recovery.Compared with mis-TLIF, mini-open TLIF reduce the fluoroscopy time and hospital costs, and also has a shorter learning curve.

[Effect of standardized treatment on reactivity of toe microcirculation in patients with type 2 diabetes mellitus].

OBJECTIVE: To evaluate the effect of standardized treatment on reactivity of the lower limb terminal microcirculation in patients with type 2 diabetes mellitus (T2DM) by high frequency ultrasound combined with warm bath. METHODS: A total of 66 patients with T2DM were collected from June 2014 to May 2015 in the Second Affiliated Hospital of Wenzhou Medical University.According to the vascular complications , the patients were divided into group A without complications (36 cases)and group B with complications (30 cases). Hemodynamic parameters such as peak systolic velocity(PSV), end-diastolic velocity(EDV) and resistance index(RI) of the right plantar digital artery on fibular side of the 1st toe were acquired through Doppler in all subjects.Then the above operation were performed repetitively on all subjects after the right foot was immersed in 40 ℃ warm water for 5 minutes.The change rates of PSV, EDV and RI were calculated after warm bath.All subjects were examined again after three months treatment .The growth rates of the change rate of PSV, EDV and RI were calculated after treatment.All parameters were analyzed. RESULTS: The change rates of the parameters in group B before and after treatment were lower than those of group A, before treatment (0.108±0.077 vs 0.184±0.091, P=0.037, 0.184±0.101 vs 0.380±0.167, P=0.002, 0.007±0.004 vs 0.015±0.008, P=0.028 7), after treatment (0.155±0.111 vs 0.421±0.138, 0.287±0.108 vs 0.794±0.286, 0.012±0.008 vs 0.039±0.014, P=0.000); the post treatment growth rates of the change rates of the parameters in group B were all less than those of group A (0.414±0.303 vs 2.192±2.673, P=0.048, 0.660±0.406 vs 1.422±1.075, P=0.042, 0.633±0.830 vs 2.191±2.269, P=0.048). The change rates of the parameters in two groups after treatment were higher than those before treatment (all P<0.05). CONCLUSION: Warm bath test can be used to detect change degree of hemodynamic parameters in patients with T2DM so as to evaluate reactivity of blood microcirculation, which has a certain clinical application value in treatment.
