OBJECTIVE To analyze the influential factors for rivaroxaban-induced bleeding events in patients with non- valvular atrial fibrillation （NVAF） and coronary heart disease. METHODS A total of 64 hospitalized patients with NVAF complicated with coronary heart disease who were treated with rivaroxaban and admitted to the Fuzhou University Affiliated Provincial Hospital from November 2021 to May 2023 were included in this retrospective study. The demographic data， laboratory test indexes and other general clinical data， and steady-state trough concentration of rivaroxaban were collected， and the dose- adjusted trough concentration was calculated. The occurrence of bleeding events within 6 months after discharge was recorded. The univariate analysis and binary Logistic regression analysis were adopted to determine the independent risk factors of rivaroxaban- related bleeding events. The binary Logistic regression equation was constructed to predict the probability of bleeding events. The area under the receiver operator characteristic （ROC） curve （AUC） was used to analyze the predictive value of the regression equation. RESULTS Among 64 patients， 19 patients had 24 case-times bleeding events， most of which were mild bleeding （19 case-times， 79.2%）， and mainly gastrointestinal bleeding （17 case-times， 70.8%）. After symptomatic treatment and adjustment of the anticoagulant regimen， most of them were improved or cured. In the univariate analysis， the proportion of patients with a history of anemia， platelet count， urea nitrogen content， steady-state trough concentration of rivaroxaban， dose-adjusted trough concentration and coagulation indexes [international normalized ratio， prothrombin time （PT）， activated partial thromboplastin time] in bleeding group were significantly more or higher than those in non-bleeding group， while the albumin level was significantly lower than that in non-bleeding group （P＜0.05）. In binary Logistics regression analysis， high PT level （odds ratio＝1.473， 95% confidence interval＝1.103-1.967， P＝ 0.009） and high rivaroxaban dose-adjusted trough concentration （odds ratio＝1.174， 95% confidence interval＝1.018-1.355， P＝ 0.027） were independent risk factors for rivaroxaban-related bleeding events. The binary Logistic regression equation of bleeding event prediction probability （P） was LogitP＝－6.975+0.387×PT level+0.161×dose-adjusted trough concentration， and the AUC of the ROC curve was 0.825 （95% confidence interval was 0.708-0.909， P＜0.001）. CONCLUSIONS The risk factors of rivaroxaban-related bleeding events in patients with NVAF and coronary heart disease include previous anemia history， high platelet count， high urea nitrogen content， high rivaroxaban steady-state trough concentration， high dose-adjusted trough concentration， high coagulation indexes and low albumin level. High PT level and high dose-adjusted trough concentration are independent risk factors that can be used to predict the risk of rivaroxaban-induced bleeding events. The regression equation has good predictive value.

In order to determine the changes of bacterial community structure and function in the early, middle and late stage of aerobic composting of chicken manure, high-throughput sequencing and bioinformatics methods were used to determine and analyze the 16S rRNA sequence of samples at different stages of composting. Wayne analysis showed that most of the bacterial OTUs in the three composting stages were the same, and only about 10% of the operational taxonomic units (OTUs) showed stage specificity. The diversity indexes including Ace, Chao1 and Simpson showed a trend of increasing at first, followed by decreasing. However, there was no significant difference among different composting stages (P < 0.05). The dominant bacteria groups in three composting stages were analyzed at the phylum and genus levels. The dominant bacteria phyla at three composting stages were the same, but the abundances were different. LEfSe (line discriminant analysis (LDA) effect size) method was used to analyze the bacterial biological markers with statistical differences among three stages of composting. From the phylum to genus level, there were 49 markers with significant differences among different groups. The markers included 12 species, 13 genera, 12 families, 8 orders, 1 boundary, and 1 phylum. The most biomarkers were detected at early stage while the least biomarkers were detected at late stage. The microbial diversity was analyzed at the functional pathway level. The function diversity was the highest in the early stage of composting. Following the composting, the microbial function was enriched relatively while the diversity decreased. This study provides theoretical support and technical guidance for the regulation of livestock manure aerobic composting process.

Objective:To summarize the characteristics of nailfold capillaroscopy (NC) in patients with systemic lupus erythematosus (SLE) and explore its clinical significance.Methods:NC examination was performed in 162 SLE patients. The clinical data of SLE patients was collected. Tianniu NC scoring standard was used. The t test was applied to analyze the measurement data, the χ2 test was applied to analyze the counting data. the Pearson or Spearman test was used to evaluate the correlative factors of NC in patients with SLE. Results:NC abnormalities were seen in 87.7%(142/162) of SLE patients, and the incidence of mild, moderate and severe abnormalities was 29.0%(47 cases), 45.1%(73 cases) and 13.6%(22 cases) respectively. The most common NC abnormal manifestation in SLE patients was decreased blood flow velocity (86.4%). In patients with moderate to severe NC abnormalities, the proportions of patients with Raynaud's phenomenon (37.9% vs 23.9%, χ2=2.955, P=0.043) and interstitial lung disease (8.0% vs 0, χ2=5.213, P=0.023), and the level of D-Dimer [(1 992±2 279) μg/L vs (1 248±1 721) μg/L, t=-1.624, P=0.013] were significantly higher than those in the groups with normal/mild NC abnormalities. Correlation analysis demonstrated that Raynaud's phenomena, interstitial lung disease, pulmonary hypertension and D-Dimer were positively correlated with the NC abnormality. Conclusion:NC abnormalities are common in SLE patients. Decreased blood flow velocity is the most frequent manifestation. SLE patients with moderate to severe NC abnormalities should be actively screened for pulmonary hypertension and interstitial lung disease.

Objective To investigate the application value of magnetic resonance imaging (MRI) examination in the efficacy evaluation of infliximab combined with seton placement for perianal fistulizing Crohn's disease (PFCD) and influencing factors of deep remission.Methods The retrospective case-control study was conducted.The clinicopathological data of 57 patients with PFCD who were admitted to the Affiliated Hospital of Nanjing University of Chinese Medicine from August 2010 to October 2017 were collected.There were 39 males and 18 females,aged (24±9)years,with a range of 14-58 years.Patients underwent MRI examination preoperatively and postoperatively.Observation indicators:(1) follow-up situations;(2) influencing factors analysis of deep remission of PFCD.Follow-up using outpatient and inpatient reexamination was performed to detect clinical recovery of patients up to October 2017.Measurement data with normal distribution were represented as Mean±SD.Measurement data with skewed distribution were described as M (range).Count data were represented as absolute number or percentage.The univariate analysis was performed using the chi-square test.The multivariate analysis was done using the logistic regression model,using P＜0.15 as an inclusion criteria in the univariate analysis.Results (1) Follow-up situations:57 patients with PFCD undergoing inflixmab combined with seton placement were followed up for (40±24)months.During the follow-up,24 of 57 patients had clinical response,33 had long-term clinical healing.The fistulas of 24 patients with clinical response presented as high signal on T2 weighted image (T2WI) of postoperative MRI.Of 33 patients with long-term clinical healing,the fistulas of 16 patients with deep remission presented loss of high signal and replacement of fibrosis tissue on T2WI of postoperative MRI,the fistulas of 17 patients without deep remission presented as high signal on T2WI of postoperative MRI.(2) Influencing factors analysis of deep remission of PFCD:results of univariate analysis showed that extent of fistula was related factors affecting deep remission of PFCD (x2 =4.312,P＜0.05).Results of multivariate analysis showed that a single fistula complicated with branches and times of infliximab maintenance treatment ≤3 were independent risk factors affecting deep remission of PFCD (odds ratio=4.377,4.296,95％ confidence interval:1.124-17.043,1.158-15.940,P＜0.05) and fistula under levator ani muscle was an independent protective factor affecting deep remission of PFCD (odds ratio =0.182,95％ confidence interval:0.041-0.815,P＜ 0.05).Conclusions Partial patients with long-term clinical healing can achieve deep remission after Infliximab combined with seton placement for perianal fistulizing Crohn's disease,requiring MRI examination to further evaluate recovery situations.A single fistula complicated with branches and times of infliximab maintenance treatment ≤ 3 are independent risk factors affecting deep remission of PFCD and fistula under levator ani muscle is an independent protective factor affecting deep remission of PFCD.

With high morbidity and mortality, lung cancer is a major threat to human health and one of the focuses of tumor researches. Lung cancer stem cells (LCSCs) are regarded as a subpopulation of cells within lung cancer tissues with the capacity of self-renewal and differentiation, and might be related to tumorigenesis and heterogeneity of lung cancer. Tumor recurrence, metastasis and drug resistance of lung cancers could be clarified by LCSC hypothesis. Thus it's therapeutically prospective to target at these cells. This review summarizes the biomarkers of LCSCs and their aberrant signal pathways, as well as the therapeutic strategies targeting at LCSCs.

Objective: To evaluate the relationship between visceral pleural invasion (VPI) and other clinicopathological features in lung adenocarcinoma with tumor size ≤3 cm, and to investigate the impact of VPI on the patients′ prognosis. Methods: The clinical and pathological features were retrospectively reviewed in 231 cases of lung adenocarcinoma with the largest diameter of tumor ≤3 cm, following complete resection and systemic lymphadenectomy. VPI was divided into three grades, PL0, PL1 and PL2 according to modified Hammar classification for lung cancer upon elastic fiber staining. Survival analysis was performed by Kaplan-Meier method, and the risk factors for prognosis were explored by Cox proportional hazards model. Patient prognosis was evaluated by progression-free survival (PFS) and overall survival (OS). Results: In all 231 cases, the number of patients with VPI was 70 (30.3%), of which 61 cases were PL1 and 9 cases were PL2. The remaining 161 cases (69.7%) had no VPI (PL0). The tumor size (P=0.003), histological grade (P<0.01), the presence of solid component (P=0.001) and micropapillary component (P=0.009), N stage (P<0.01) and TNM stage (P<0.01) were significantly correlated with VPI. Patients with VPI had significantly shorter PFS and OS than those without VPI (P<0.01). There were significant differences in PFS and OS between patients with different VPI levels (P<0.01). Cox multivariate regression analysis showed that VPI was not an independent prognostic factor, whereas PL2 was an independent prognostic factor for PFS (P=0.007), but not an independent prognostic factor for OS (P=0.052). Conclusions For patients with lung adenocarcinoma of tumor size ≤3 cm, VPI is related to poor prognosis; However, only PL2 is an independent prognostic factor for PFS. It may be not necessary to separate PL0 and PL1 status in smaller lung adenocarcinomas. Therefore, the definition of VPI may need further modification through large cohort studies.

Objective To evaluate the efficacy of infliximab combined with sphincter-sparing surgery in treatment of perianal Crohn's disease.Methods Clinical data of 49 patients with perianal Crohn's disease (3 cases with nonfistulizing perianal Crohn's disease and 46 cases with fistulizing perianal Crohn's disease) receiving infliximab combined with sphincter-sparing surgery in Jiangsu Province Hospital of TCM from May 2010 to June 2014 were analyzed retrospectively.The situation of fistula closure was assessed.C-reactive protein and perianal disease activity index were estimated by Wilcoxon method.Results No patient was failed to respond to primary treatment.patients (26/46) had a complete response to treatment,28.3％ patients (13/46) had a partial response and 15.2％ patients (7/46) had lost response to treatment;2 cases of anal ulcer healing;No other perianal lesion occurred in 1 case of verrucous skin.At final follow-up,CRP was decreased to [4.5 (1.5,15.9)] mg/Lfrom [16.9(6.6,35.6)] mg/L(Z=-3.994,P=0.00);PDAI was decreased to[1(0,4.5)]from [7(4.5,10.5)] (Z=-6.100,P=0.00).Conclusion Infliximab combined with sphincter-sparing surgery is effective for perianal Crohn's disease.

OBJECTIVETo discuss the clinical features of perianal Crohn disease (PCD).

METHODSClinical data of 52 PCD patients who were treated at the Department of Colorectal Surgery, Affiliated Hospital of Nanjing University of Chinese Medicine from June 2011 to October 2014 were analyzed retrospectively. Montreal classification, clinical symptoms, the subtype of perianal lesions, history of perianal surgery and medical treatment, disease active indexes, serum inflammation markers and nutritional indexes were included.

RESULTSAmong 52 patients, there were 40 males and 12 females with a mean age of (27.9±9.1) years. According to Montreal classification, 51.9%(27/52) of patients had ileocolic involvement and 75.0%(39/52) had inflammatory disease behavior. Thirteen (25.0%) and 15(28.8%) patients had abdominal pain and diarrhea respectively at admission. With respect to the subtype of perianal lesions, there were 32(61.5%) cases of anal fistula and 16(30.8%) cases of perianal abscess. Thirty-nine(75.0%) and 33(63.5%) patients had a history of perianal surgery and medical treatment before admission resepectively. Laboratory findings revealed high C-reaction protein level in 63.5%(33/52), high erythrocyte sedimentation rate in 61.5%(32/52), elevated platelet in 32.7%(17/52), low body weight in 44.2%(23/52), low albumin in 26.9%(14/52) and anemia in 42.3%(22/52) of patients.

CONCLUSIONSThe clinical features of PCD patients include male predominant, early onset disease, high prevalence of ileocolic involvement and inflammation disease behavior. Features prompting underlying PCD diagnosis include characteristic gastrointestinal symptoms, requiring multiple perianal surgery, and abnormality of inflammation markers and nutritional indexes.

Objective To investigate the clinical characteristics of perianal Crohn's disease (CD) with or without proctitis and compare the treatment effect of surgery combined with biological preparation.Methods The retrospective cohort study was conducted.The clinical data of 52 patients with perianal CD who were admitted to the Affiliated Hospital of Nanjing University of Traditional Chinese Medicine from June 2011 to October 2014 were collected.Thirty patients with inflammation involvement of the rectum and 22 patients without inflammation involvement of the rectum were respectively divided into the proctitis group and non-proctitis group.All the 52 patients underwent surgery combined with infliximab therapy.Observation indicators included:(1) clinical characteristics:gender,age,body mass index (BMI),lesion location,disease behavior,type of perianal lesions,history of perianal surgeries,CD activity index (CDAI),perianal disease activity index (PDAI),C-reactive protein (CRP),erythrocyte sedimentation rate (ESR),white blood cell (WBC),platelet (PLT) and albumin (Alb),(2) treatment and follow-up.Follow-up using outpatient examination was performed to evaluate the perianal lesions up to December 2015.Measurement data with normal distribution were described as-x ± s and comparison between groups was analyzed by the t test.Count data were described as the percentage,and comparison between groups was analyzed by the chi-square test and Fisher's exact probability.Results (1)Clinical characteristics:number of patients with BMI ＜ 18.5 kg/m2 and with normal BMI were respectively 17,13 in the proctitis group and 6,16 in the non-proctitis group.Lesions located at ileum,colon and ileocolon were respectively detected in 3,9,18 patients in the proctitis group and 9,4,9 patients in the non-proctitis group.CDAI≥ 150 and ＜ 150,CRP≥8 mg/L and ＜ 8 mg/L,ESR ＞ normal level and =normal level,Alb ＜ 35 g/L and between 35 g/L and 50 g/L were respectively detected in 23,7,25,5,24,6,12,18 patients in the proctitis group and 8,14,8,14,8,14,2,20 in the non-proctitis group,with statistically significant differences between the 2 groups (x2 =4.446,6.855,8.563,12.076,10.211,6.163,P ＜ 0.05).(2) Treatment and follow-up:all the 52 patients underwent more than 3 times infliximab therapies and perianal surgeries within 1 week after infliximab therapy.All the patients were followed up for a median time of 28 months (range,8-52 months).Thirty-four patients still underwent maintenance therapy of immunosuppressive agents and 18 didn't undergo maintenance therapy up to the end of follow-up.Twenty-two patients in the proctitis group and 12 patients in the non-proctitis group underwent maintenance therapy,with no statistically significant difference between the 2 groups (x2 =1.979,P ＞ 0.05).The total healed rate,improvement rate and unhealed rate of perianal lesion were 55.8％ (29/52),34.6％ (18/52) and 9.6％ (5/52),respectively.The number of patients with healed,improved and unhealed perianal lesions were 16,11,3 in the proctitis group and 13,7,2 in the non-proctitis group,respectively,showing no significant difference in treatment effects between the 2 groups (x2 =O.173,P ＞ 0.05).Conclusions Patients with perianal CD combined with proctitis have higher activity of intestinal inflammation and worse nutritional status compared with patients without proctitis.However,there is no significant difference in the type and activity of perianal lesion between patients with or without proctitis.Surgery combined with biological preparation could render better clinical outcomes in treatment of perianal CD with proctitis.

Crohn's disease (CD) is a chronic nonspecific inflammatory disease.CD can affect any location in the digestive tract,and it also affect other organs,including the eyes,skin,liver and joints,which are termed extraintestinal manifestations (EIMs).The cutaneous manifestations of CD are common and occur in about one-third of patients.EIMs of CD have been divided into 3 categories.(1) Specific lesion,cutaneous manifestations of CD were the same as histopathologic findings of underlying gastrointestinal lesion.(2) Reactive lesion,it was also inflammatory lesion which was usually accompanied by underlying gastrointestinal disease while inflammatory injury was different from histopathologic findings of gastrointestinal lesion.(3) Associated lesion,it was caused by sequelae of human leucocyte antigen and chronic inflammation.In the current era of ever-expanding therapeutic options for CD,some investigators have proposed a fourth category of EIMs,namely those that are therapy-related lesion.The therapy-related lesion is closely related to disease-associated conditions in light of certain skin findings,and there is potential overlap between them.
