ABSTRACT

Objective:To evaluate the feasibility and effectiveness of sentinel lymph node (SLN) detection in the ovarian neoplasms.Methods:A search of the literature describing ovarian SLN was performed using China National Knowledge Infrastructure (CNKI), WANFANG DATA, VIP, PubMed, Embase, web of science, Cochrane library from 2000.01.01 to 2020.07.29. The quality evaluation and data extraction of the included literature were conducted, and the development rate, sensitivity and negative predictive value of SLN were calculated.Results:Eight prospective single-arm studies were included, with heterogeneity I2=57.41%>50%, and the P<0.1. A total of 96 patients with ovarian cancer [Stage International Federation of Gynecology and Obstetrics (FIGO)Ⅰ-Ⅱ] were included, of whom 93 completed systematic pelvic and para-aortic lymphadenectomy after SLN detection. The most common tracers were technetium-99m radioactive colloid ( 99Tc m), blue dye or indocyanine green (ICG), and the most common injection sites were the infundibulopelvic ligaments and the proper ovarian ligaments. The SLN detection rate was 88.5%(85/96) and the average number was 2-3. SLN was found in the ipsilateral or contralateral regions of the tumor, 40.8%(31/76) was found only in the para-aortic, 14.5%(11/76) was found only in the pelvic, and 44.7%(34/76) was found only in the para-aortic and pelvic region. The sensitivity was 90.9%(10/11) and the negative predictive value was 98.8%(82/83) of lymph node metastasis. Conclusions:SLN detection for ovarian neoplasms is feasible, and whether it can effectively predict lymph node status of ovarian cancer still needs large sample, multi-center, prospective clinical studies to further verify.

ABSTRACT

Lymph node metastasis represents a common way of distant spread of gynecologic malignancies and an independent risk factor of poor prognosis of patients. The pelvic and paraaortic lymphadenectomy is a critical part of the surgical treatment of gynecologic cancer, which potentially improves the survival outcomes of patients through clarifying the node status to guide the subsequent management and/or removal of positive nodes to reduce the tumor burden. However, when we make a decision about lymphadenectomy, we should balance the related survival benefits and morbidities impacting the long-term quality of life. It is noteworthy that the principles of lymph node management are varied between different types and different stages of tumors characterized with different clinical features. Moreover, the sentinel lymph node biopsy, which has been emerging as a promising alternative to traditional systematic lymph node dissection, provides new options while bringing new issues. Here, based on the latest progress in relevant fields, we attempt to figure out the distinct features and unanswered questions in the management of lymph nodes of patients with cervical cancer, endometrial cancer, and ovarian cancer, which may trigger meaningful thoughts regarding related clinical decision.

ABSTRACT

Objective:To investigate the characteristics of event-related potentials(ERPs)P300 in the development of attention cognitive function of school-age children.Methods:A total of 180 school-age children were divided into 3 groups according to their ages (7-8 years old group with 48 cases, 9-10 years old group with 44 cases and 11-12 years old group with 48 cases). All of the participants completed an Oddball task, and their behavioral data, P3a and P3b components of ERPs were analyzed by SPSS 21.0.Results:(1)The differences of hit numbers(49(47.25, 50), 50(49, 50), 50(50, 50) ), correct reaction time((533.37±56.94) ms, (486.91±61.12) ms, (411.55±51.97) ms), and Omission errors (2(1, 4), 2(1, 3), 1(0, 2) ) among the three groups were statistically significant( F/χ 2=20.635, 54.477, 13.169, all P<0.01). (2)There was a main effect of age( F=3.884, P=0.023) and an interaction effect between age and condition( F=3.314, P=0.038) on the amplitude of P3a, while the main effect of condition was not significant( F=0.111, P=0.740). The amplitude of P3a component in 11-12 years old group ((11.02±6.00)μV) was significantly larger than that of 7-8 years old group ((7.36±4.48)μV) and 9-10 years old group ((7.76±5.17)μV, both P<0.05). However, there was no significant interaction effect between age and condition on P3a latency, P3b amplitude and latency ( P>0.05). Conclusion:P3a may be a sensitive indicator of cognitive function in school-age children, and the age of 11-12 years old is a sensitive period for the development of children's attention orientation and selection ability, which may be related to the development of brain network.

ABSTRACT

Objective To establish an ARIMA model and a seasonal index model to predict the trend of mumps, compare the advantages and disadvantages of the two models, and to provide a scientific basis for the prevention and control of mumps. Methods ARIMA model and seasonal index model were established based on the monthly incidence of mumps in Hubei Province from 2008 to 2019. Results The average annual incidence rate from 2008 to 2019 was 28.89 / 100,000. April-July was the month of high incidence. The established ARIMA model and seasonal index model were (1-1.070B+0.441B2-0.291B3)*(1-B12)*Xt=(1-0.611B12)*Ɛt and Xt=(2.802-0.006t)*St. The average relative errors of the ARIMA model and the seasonal index model were 11.49% and 20.86%, respectively. Conclusion The ARIMA model and the seasonal index model both have good applicability in predicting the onset time characteristics and trend of mumps. However, while the ARIMA model demonstrated more advantages in fitting the annual change trend, the seasonal index model is better in fitting the monthly change trend. The two models can be used in combination to predict the trend of mumps.

ABSTRACT

Objective To provide reference for formulating scarlet fever prevention and control strategies by analyzing the epidemiological characteristics and predicting the incidence trend of scarlet fever. Methods Spearman correlation analysis, clustering analysis, seasonal index model and seasonal ARIMA model were used for analysis and prediction. Results The average annual incidence of scarlet fever in 2010-2018 was 1.37/100 000, and there was a positive correlation between annual incidence and year (rs=0.817,P=0.007). April-June and November-December were high incidence months. The clustering analysis was significant(F=4795.30,P<0.001), showing that the high-incidence areas are Shennongjia, Yichang, Enshi, Wuhan. Reported cases were concentrated in 1-14 years old, mainly for students, child care children and scattered children. The incidence rate of males was higher than that of females. The optimal model is ARIMA(0,1,1)(0,1,0)12. The prediction showed that the monthly incidence characteristics of 2019 were consistent with previous years, and the annual incidence rate was 10.22/100 000(95% CI:2.33/100 000-30.43/100 000), which was higher than the incidence of 2018. Conclusions The incidence of scarlet fever in Hubei Province is generally on the rise from 2010 to 2018. The incidence is bimodal. Students are the main disease group. The incidence rate of males is higher. The incidence is mainly concentrated in the mountainous areas of southwest and capital cities. The ARIMA model has a good applicability in the prediction of scarlet fever. The incidence level will continue to rise in 2019, and it is necessary to strengthen monitoring and control measures with reference to epidemiological characteristics.

ABSTRACT

OBJECTIVE@#To evaluate the clinical efficacy and safety of Congrong Shujing Granules ( , CSGs) in treating patients with Parkinson's disease (PD) and Chinese medicine (CM) syndrome of Shen (Kidney) essence deficiency, and to investigate the potential mechanism involving efficacy through a transcriptome sequencing approach.@*METHODS@#Eligible PD patients with syndrome of Shen essence defificiency were randomly assigned to a treatment group or a control group by a random number table, and were treated with CSGs combined with Western medicine (WM), or placebo combined with WM, respectively. Both courses of treatment lasted for 12 weeks. The Unifified Parkinson's Disease Rating Scale (UPDRS) score, the PD Question-39 (PDQ-39) score, CM Syndrome Scale score, and drug usage of all patients were evaluated before and after treatment. Safety was evaluated by clinical laboratory tests and electrocardiographs. Blood samples from 6 patients in each group were collected before and after the trial and used for transcriptomic analysis by gene ontology analysis and Kyoto Encyclopedia of Genes and Genomes pathway analysis. Differentially expressed genes were validated using reverse transcription-polymerase chain reaction.@*RESULTS@#A total of 86 PD patients were selected from the Third Affifiliated People's Hospital of Fujian University of Traditional Chinese Medicine between January 2017 and December 2017. Finally, 72 patients completed the trial, including 35 in the treatment group and 37 in the control group. When compared with the control group after treatment, patients in the treatment group showed signifificant decreases in UPDRS sub-II score, PDQ-39 score, CM syndrome score, and Levodopa equivalent dose (P0.05). A possible mechanism of clinical effificacy was proposed that involved regulating cell metabolism-related processes and ribosome-related pathways. Treatment with CSGs had shown to affect relevant gene loci for PD, including AIDA, ANKRD36BP2, BCL2A1, BCL2L11, FTH1P2, GCH1, HPRT1, NFE2L2, RMRP, RPS7, TGFBR1, WIPF2, and COX7B.@*CONCLUSIONS@#CSGs combined with WM can be used to treat PD patients with CM syndrome of Shen essence defificiency with a good safety. The possible mechanism of action and relevant gene loci were proposed. (Registration No. ChiCTR-IOR-16008394).

ABSTRACT

Leptomeningeal metastasis (LM) is one of the serious complications of advanced non-small cell lung cancer (NSCLC), although the incidence is not high, the clinical symptoms are severe and the prognosis is poor. LM is prone to occur in patients with positive driver gene than negative. At present, the treatment of LM mainly includes molecular targeted therapy, systemic chemotherapy, whole brain radiotherapy, intrathecal chemotherapy and immunotherapy. Although there are many treatments, the efficacy of LM is still unsatisfactory. This article reviews the drug therapy of sensitive driver gene positive NSCLC LM.

ABSTRACT

Objective:To investigate the synergistic effect of sarcopenia and osteoporosis on the occurrence of spinal osteoporotic fracture (OPF) in patients with rheumatoid arthritis (RA).Methods:A total of 389 hospitalized RA patients and 156 age and sex-matched normal subjects (control group) were recruited. Dual energy X-ray absorptiometry (DEXA) method was used to measure bone mineral density (BMD) of lumbar spine and hip, and bioelectrical impedance method was applied to determine skeletal muscle mass of limbs. X-ray examination of spin was conducted and spinal OPF was diagnosed according to semi-quality method. Student's t test was used for comparison of measurement date between the two groups, χ2 test was used for comparison of intergroup rates, and Logistic Regression(Backward LR) method was used for multivariate Regression analysis of binomial classification data. Results:BMD of all test sites in RA patients was significantly lower than that in the control group ( P<0.01). The incidence of total OP in RA group was significantly higher than that in the control group [(32.9% vs 12.8%), χ2=22.706, P<0.01]. A total of 84 patients with RA developed spinal OPF, with an incidence of 21.6% which was higher than that in the control group [(3.8%), χ2=25.439, P<0.01]. The incidence of sarcopenia in RA was 54.8%, significantly higher than that in the control group [(9.6%), χ2=93.241, P<0.01]. The incidence of sarcopenia combined with osteoporosis in RA group (28.5%) was significantly higher than that in the control group [(5.8%), χ2=118.110, P<0.01]. Comparison of the incidence of spinal OPF in RA patients among groups with different bone mass (normal bone mass, osteopenia, osteoporosis) showed that the incidence of spinal OPF among these groups was statistically different ( χ2=43.373, P<0.01), and the incidence of spinal OPF increased along with the decrease of bone mass ( χ2=43.003, P<0.01). The incidence of spinal OPF in RA patients with sarcopenia (27.2%, 58/213) was significantly higher than that in RA patients without sarcopenia [(14.8%, 26/176), χ2=8.833, P=0.003]. All participants were divided into three groups: group 1=no OP and sarcopenia, group 2=with sarcopenia or OP, group 3=both sarcopenia and OP. Difference of incidence of spine OPF in RA patients among three groups was statistically significant ( χ2=33.832, P<0.01), and the incidence of spinal OPF raised gradually in group 1 and 3, ( χ2=37.164, P<0.01). Incidences of sarcopenia, OP and spinal OPF in RA treated with glucocorticoid (GC) were higher than those in RA without GC ( P<0.05, P<0.01). Results of logistic regression showed advanced age[ OR(95% CI)=1.069(1.038, 1.101), P<0.01], usage of GC [ OR(95% CI)=3.169(1.679, 5.984), P<0.01] and sarcopenia combined with OP [ OR(95% CI)=2.113(1.430, 3.124), P<0.01] were risk factors for spinal OPF in RA patients. Conclusion:Incidences of sarcopenia, OP and spinal OPF in RA patients are higher than that in normal controls. Sarcopenia and OP have a synergistic effect on spinal OPF in RA patients.

ABSTRACT

Objective: To investigate the neuroprotective mechanism of salidroside after ischemic stroke and its regulation mechanism in TGF-β1/Smad3 signaling pathway. Methods: A total of 48 SPF SD male rats aged 12-15 weeks were randomly divided into four groups (n = 12): Sham-operated group (sham group), model group, salidroside group (treatment group), and signaling pathway-enhanced intervention group (TGF-β1 group). In the model group, treatment group, and TGF-β1 group, a permanent focal cerebral ischemia rat model was established by suture method, and the sham group was not inserted with nylon thread. 48 h before the modeling operation, the treatment group and the TGF-β1 group were given drug intervention at a fixed time every morning: the treatment group was administered with 10 mg/kg salidroside ventricle, and the TGF-β1 group was treated with 20 mg/kg TGF-β1. The intraventricular injection was administered, and the sham group and the model group were given an equal volume of physiological saline. After 14 d of continuous administration, each group of rats was sacrificed by decapitation. TTC staining, Nissl staining, TUNEL staining, immunofluorescence, and Western blot were used to determine the infarct volume, the number of intact neurons, the cell apoptosis, the expression of Bax and Bcl-2 expression, the expression levels of Bax, Bcl-2, TGF-β1, and p-Smad3. The ultrastructural changes of brain tissue were observed by electron microscopy. Results: Compared with the sham group, the cerebral infarction volume of the model group was significantly increased, the number of intact neurons in the brain tissue was significantly reduced, the apoptosis rate of nerve cells was significantly increased, and the expression of Bax was significantly increased, the expression of Bax was significantly decreased. The expression of TGF-β1 and p-Smad3 was significantly increased, and the difference was statistically significant (P 0.05). Conclusion: Salidroside can activate the TGF-β1/Smad3 signaling pathway after ischemic stroke, thereby alleviating neurological damage and exerting protective effects on nerve cells.

ABSTRACT

OBJECTIVE@#To investigate the clinical efficacy of ALL-2005 and ALL-2009 regimen and factors influencing prognosis of newly diagnosed ALL patients aged between 10-18 years old to provide some reference for clinical diagnosis and treatment.@*METHODS@#The clinical data including baseline clinical characteristics, induction chemotherapy effect, long-term clinical efficacy, recurrence rate and mortality of induction therapy of 119 newly diagnosed ALL patients aged between 10-18 years old from January 2008 to December 2015 were analyzed retrospectively, and the influencing factors of clinical prognosis were evaluated by univariate and multivariate analysis.@*RESULTS@#The complete remission rate at the 5th week after induction therapy was not significantly different between ALL-2005 and ALL-2009 regimen groups (P>0.05). The cumulative event-free survival rate and overall survival rate of 119 cases after 5-year follow-up were (63.41±3.65)% and (68.95±4.01)% respectively, and after 7-year follow-up were (61.86±3.72)% and (67.22±3.59)% respectively. The cumulative event-free survival rate and overall survival rate were not significantly different between ALL-2005 and ALL-2009 regimen groups (P>0.05). The total recurrence rate, extramedullary recurrence rate, recurrence time and survival rate were not significantly different between ALL-2005 and ALL-2009 regimen groups (P>0.05). The survival rate of extramedullary recurrence group was significantly higher than bone marrow recurrence group (P<0.05). The survival rate in late term recurrence group was significantly higher than in early term recurrence group (P<0.05). The mortality of ALL-2005 regimens was not significantly different from that of ALL-2009 regimen group (P>0.05). Univariate analysis showed that age, sex, induction therapy, risk and fusion gene all were the factors influencing clinical prognosis (P<0.05). Multivariate analysis by Cox regression model showed that male, non-remission after induction therapy and high risk were the independent risk factors for poor prognosis in patients (P<0.05). The survival rate of patients with BCR-ABL@*CONCLUSION@#The survival rate of newly diagnosed ALL patients aged between 10-18 years old treated with ALL-2009 regimen was slightly higher than that of ALL-2005 regimen, it is more suitable for the ALL patients with BCR-ABL

ABSTRACT

AIM:To establish a TaqMan RT-qPCR method for surveiling the spread of oncolytic virus M1 in tissue,helping control the dosage and assessing the safety of virus. METHODS:A TaqMan-based one-step RT-qPCR method for the detection and quantification of oncolytic virus M1 in the tissues was established. The virus load and distri-bution in the tissues of SD rats,cynomolgus monkeys and nude mice were also investigated. RESULTS:A pair of specific primers(Q3)and the standard viral RNA for SYBR Green RT-qPCR were screened and selected with the best specificity and amplification efficiency. By optimizing the experiment conditions,we found that the annealing temperature above 62℃reduced matrix effect but affected the amplification efficiency. So we established a one-step TaqMan RT-qPCR method and redesigned a pair of Q3 short primers(Q3S). Using the one-step TaqMan RT-qPCR and Q3S primer,the stan-dard RNA with low copy numbers was specifically detected under the background of mixed matrix RNA of SD rats or cyno-molgus monkeys. Furthermore,the method was verified to be suitable for detecting tissue distribution of M1 virus in the mice,SD rats and cynomolgus monkeys. CONCLUSION:The TaqMan-based one-step RT-qPCR constructed with Q3S primer can be used for M1 virus quantification in various tissue samples of different animals with better specificity and sen-sitivity,and may be further applied to the detection of clinical samples.

ABSTRACT

Objective To analyze the epidemiological characteristics of measles, predict the incidence trend of the disease, and provide reference for the development of measles prevention and elimination strategies. Methods Descriptive analysis, seasonal index method, clustering analysis and ARIMA model were used for data analysis and trend prediction. Results The average annual incidence of measles in 2005-2018 was 3.01/100,000. It was at a low level after 2009, and rebounded in 2018. The seasonal index of March-June was greater than 1, which was the month of high incidence. The incidence of men was higher than that of women. The 0-3 years old and 10-30 years old groups had a high incidence, and the population was mainly scattered children, students, and nursery children. The areas with high incidence were mainly northwestern and southeastern Hubei. ARIMA (0,1,0) (0,1,1) was the optimal model. The prediction analysis showed that the incidence rate in 2019 will be 1.26/100 000. Conclusion After the implementation of booster immunization, the measles epidemic in Hubei Province was at a low level, but it fluctuated greatly in recent years and is currently showing a rising trend. The incidence was high in spring. Cases were "biphasic shift" in groups 0-3 years old and 10-30 years old. Occupational distribution was consistent with the characteristics of high incidence in the age group. The mountain areas with poor sanitary conditions and economic backwardness, and regions with large population bases and high floating populations had a high incidence. The ARIMA model had good applicability in predicting the trend of measles incidence, which shows measles will continue to rise in 2019.

ABSTRACT

Objective To explore the changes of attention cognitive function by studying Oddball task behavior and event-related potentials(ERPs) in children with first-episode tic disorder(TD). Methods Oddball task was tested in 30 children with TD and 30 normal children,and their behavioral data and P3a/P3b components of ERPs were analyzed. Results Children with TD had a lower hitting number (49(48, 50)) than control group (50(49,50),P<0. 05). The main effect of group ( F=6. 047,P=0. 015) and the interaction effect between group and condition (F=4. 619,P=0. 034) on the amplitude of P3a were signifi-cant(P<0. 05). The amplitude of P3a component ((5. 91±4. 51)μV ) in TD group were smaller than that in the control group((9. 57±5. 80)μV)(P<0. 05). However,there was no significant interaction effect be-tween group and condition on P3a latency,P3b amplitude and latency (P>0. 05). Conclusion Attentional orienting is impaired in children with TD.

ABSTRACT

In order to improve the accuracy and efficiency of automatic seizure detection, the paper proposes a method based on improved genetic algorithm optimization back propagation (IGA-BP) neural network for epilepsy diagnosis, and uses the method to achieve detection of clinical epilepsy rapidly and effectively. Firstly, the method extracted the linear and nonlinear features of the epileptic electroencephalogram (EEG) signals and used a Gaussian mixture model (GMM) to perform cluster analysis on EEG features. Next, expectation maximization (EM) algorithm was used to estimate GMM parameters to calculate the optimal parameters for the selection operator of genetic algorithm (GA). The initial weights and thresholds of the BP neural network were obtained through using the improved genetic algorithm. Finally, the optimized BP neural network is used for the classification of the epileptic EEG signals to detect the epileptic seizure automatically. Compared with the traditional genetic algorithm optimization back propagation (GA-BP), the IGA-BP neural network can improve the population convergence rate and reduce the classification error. In the process of automatic detection of epilepsy, the method improves the detection accuracy in the automatic detection of epilepsy disorders and reduced inspection time. It has important application value in the clinical diagnosis and treatment of epilepsy.

ABSTRACT

Uterine sarcoma is a rare uterine malignant tumor characterized by extremely aggressive behavior with a high recurrence rate and poor prognosis. It remains very challenging to distinguish uterine sarcomas from uterine fibroids prior to surgery because of the similar clinical manifestations and the lack of specific imaging features and tumor markers. An integrated analysis algorism including risk factors,symptoms,imaging analysis(pelvic ultrasound and MRI),and endometrial biopsy is helpful for the preoperative differential diagnosis between uterine sarcomas and uterine leiomyomas.

ABSTRACT

Objective@#To investigate the influence of tumor necrosis factor-related apoptosis-inducing ligant (TRAIL) deficiency on mice colitis and the gut microbiota composition by inclding the expermental colitis model in tumor necrosis factor-related apoptosis-inducing ligand gene knockout (TRAIL-/-) mice.@*Methods@#C57BL/6 TRAIL-/- mice and wild type (WT) mice were selected and assigned into TRAIL-/- control group (eight mice), TRAIL-/- colitis group (16 mice), WT control group (eight mice) and WT colitis group (16 mice). The mice of two colitis groups were oral administrated with 3.5% dextran sulphate sodium (DSS) in drinking water for seven consecutive days to induce experimental colitis model. The severity of colitis was evaluated by clinical appearance and histopathological examination. The colonic tissue samples of mice were collected and microbiota profile was analyzed by 16S rDNA sequencing method. USEARCH software and R language were used to analyze the difference of gut microbiota among TRAIL-/- control group, TRAIL-/- colitis group, WT control group and WT colitis group. T test and Mann-Whitney U test were used for statistical analysis.@*Results@#After modeling, the disease activity index (DAI) of WT colitis mice and TRAIL-/- colitis mice both gradually increased over time. Furthermore, compared with colitis mice, TRAIL-/- colitis mice developed body weight loss, diarrhea and hemafecia earlier. On the seventh day after modeling, the percentage of body weight loss of TRAIL-/- colitis mice and WT colitis mice was (28.98±2.84)% and (17.87±3.70)%, respectively; and the difference was statistically significant (t=9.53, P<0.01). The length of colon of TRAIL-/- colitis mice was shorter than that of WT colitis mice ((4.63±0.28) cm vs. (6.02±0.41) cm), and the difference was statistically significant (t=11.20, P<0.01). The DAI of TRAIL-/- colitis mice was higher than that of WT colitis mice (3.00±0.00 vs. 2.32±0.05), and the difference was statistically significant (t=54.40, P<0.01). The histological score of TRAIL-/- colitis mice was higher than that of WT colitis mice (6.19±0.25 vs. 3.87±0.22), and the difference was statistically significant (t=27.87, P<0.01). Under the microscope, colonic mucosal epithelial injury, crypt structure destruction and inflammatory cell infiltration were more obvious in TRAIL-/- colitis mice than in WT colitis mice. The alpha diversity of colonic flora was more significant in TRAIL-/- colitis group compared with that of WT colitis group. At the family level, the relative richness of Deferribacteraceae, Ruminococcaceae, Rikenellaceae, F16 and Paraprevotellaceae significantly increased in TRAIL-/- colitis group, but the relative richness of Enterococcaceae obviously reduced ((19.839±19.991)% vs. (7.224±11.241)%, (3.564±2.543)% vs.(2.861±3.821)%, (0.123±0.066)% vs. (0.068±0.049)%, (0.032±0.033)% vs. (0.006±0.011)%, (0.153±0.098)% vs. (0.062±0.054)% and (0.013±0.027)% vs. (0.054±0.121)%, respectively; U=51, 69, 53, 35, 49 and 69, respectively; P<0.01 and 0.05, respectively). In addition, at the genus level the relative richness of Oscillospira, Mucispirillum and Cytophaga in TRAIL-/- colitis group remarkably elevated, and the relative richness of Enterococcus significantly decreased ((2.363±2.147)% vs. (1.813±2.847)%, (19.839±19.991)% vs. (7.223±11.241)%, (0.104±0.153)% vs. (0.046±0.069)% and (0.076±0.049)% vs. (0.135±0.074)%, respectively; U=70, 51, 66 and 65, respectively; P <0.05 and 0.01, respectively).@*Conclusion@#TRAIL deficiency aggravate DSS-induced colitis, and increase the alpha diversity of colonic microbiota in colitis mice.
