Avaliação da lactoferrina e da calprotectina como marcadores de inflamação intestinal na pancreatite crônica / Evaluating lactoferrin and calprotectin as markers of intestinal inflammation inchronic pancreatitis

ABSTRACT Background: The treatment of chronic pancreatitis does not consistently solve intestinal abnormalities, and despite the implementation of various therapeutic measures, patients often continue to experience persistent diarrhea. Therefore, it is imperative to recognize that diarrhea may stem from factors beyond pancreatic insufficiency, and intestinal inflammation emerges as a potential contributing factor. Objective: The aim of this study was to assess fecal lactoferrin and calprotectin levels as indicators of intestinal inflammation in patients with chronic pancreatitis experiencing persistent diarrhea. Methods: In this study, 23 male patients with chronic pancreatitis primarily attributed to alcohol consumption and presenting with diarrhea (classified as Bristol stool scale type 6 or 7), underwent a comprehensive evaluation of their clinical and nutritional status. Fecal lactoferrin and calprotectin levels were mea­sured utilizing immunoassay techniques. Results: The average age of the participants was 54.8 years, 43.5% had diabetes, and 73.9% were smokers. Despite receiving enzyme replacement therapy and refraining from alcohol for over 4 years, all participants exhibited persistent diarrhea, accompanied by elevated calprotectin and lactoferrin levels indicative of ongoing intestinal inflammation. Conclusion: The findings of this study underscore that intestinal inflammation, as evidenced by elevated fecal biomarkers calprotectin and lactoferrin, may contribute to explaining the persistence of diarrhea in patients with chronic pancreatitis.

RESUMO Contexto: O tratamento da pancreatite crônica não resolve de forma consistente as anomalias intestinais e, apesar da implementação de várias medidas terapêuticas, os pacientes muitas vezes continuam a apresentar diarreia persistente. Portanto, é imperativo reconhecer que a diarreia pode resultar de fatores além da insuficiência pancreática, e a inflamação intestinal surge como um potencial fator contribuinte. Objetivo: O objetivo deste estudo foi avaliar os níveis fecais de lactoferrina e calprotectina como indicadores de inflamação intestinal em pacientes com pancreatite crônica com diarreia persistente. Métodos: Neste estudo, 23 pacientes do sexo masculino com pancreatite crônica atribuída principalmente ao consumo de álcool e apresentando diarreia (classificada na escala de fezes de Bristol tipo 6 ou 7), foram submetidos a uma avaliação abrangente de seu estado clínico e nutricional. Os níveis fecais de lactoferrina e calprotectina foram medidos utilizando técnicas de imunoensaio. Resultados: A idade média dos participantes foi de 54,8 anos, 43,5% tinham diabetes e 73,9% eram fumantes. Apesar de receber terapia de reposição enzimática e abster-se de álcool por mais de 4 anos, todos os participantes apresentaram diarreia persistente, acompanhada por níveis elevados de calprotectina e lactoferrina, indicativos de inflamação intestinal contínua. Conclusão: Os achados deste estudo ressaltam que a inflamação intestinal, evidenciada pelos biomarcadores fecais elevados calprotectina e lactoferrina, pode contribuir para explicar a persistência da diarreia em pacientes com pancreatite crônica.

Obstrucción intestinal por fecaloma gigante en adolescente con enfermedad de Hirschsprung

La enfermedad de Hirschsprung (EH) es infrecuente y la mayoría de los escasos casos se presentan en neonatos, raramente se diagnostica durante la adolescencia y menos son los casos documentados. Se presenta el caso de un varón de 16 años quien experimentó 15 días de estreñimiento, anorexia, vómitos postprandiales y distensión abdominal. Los exámenes imagenológicos mostraron un fecaloma masivo que obstruía el colon, y el examen anatomopatológico señaló EH. Ante el fracaso de medidas conservadoras de evacuación se realizó una hemicolectomía izquierda ampliada y una colostomía, más apendicectomía por obstrucción intestinal. El paciente fue dado de alta con antibioticoterapia. Este caso resalta la importancia de considerar EH en adolescentes con estreñimiento crónico y masas abdominales. Aunque los pacientes pueden experimentar problemas postoperatorios, la cirugía es el tratamiento más efectivo para la EH.

Hirschsprung's disease (HD) is uncommon, and most of the cases occur in neonates. It is rarely diagnosed during adolescence, and even fewer cases are documented. We present the case of a 16-year-old male who had 15 days of constipation, anorexia, postprandial vomiting and abdominal distension. Imaging examinations showed a massive fecaloma obstructing the colon, and histopathological examinations showed HD. Given the failure of conservative evacuation measures, an extended left hemicolectomy and colostomy were performed, plus appendectomy for bowel obstruction. The patient was discharged with antibiotic therapy. This case highlights the importance of considering HD in adolescents with chronic constipation and abdominal masses. Although patients may experience postoperative problems, surgery is the most effective treatment for HD.

Diagnostic Efficacy of Fecal Calprotectin in Inflammatory Bowel Disease: Systematic Literature Review

Introduction: Inflammatory bowel disease is a group of pathologies that include ulcerative colitis and Crohn's disease, which have similar manifestations. Currently, the diagnosis and monitoring of this disease rely mainly on endoscopic studies. Still, this method can hardly be applied to periodic disease monitoring as it is expensive, invasive, and not readily available. Fecal calprotectin is widely known, easy to use, and affordable, and it is currently the best-characterized biomarker for this pathology. Materials and methods: The research design is a systematic diagnostic test validation literature review. A search was conducted in different databases using the QUADAS-2 checklist to evaluate the methodological quality. Results: The initial search yielded 352,843 articles published chiefly in PubMed, followed by Scopus and Science Direct. After multiple filters, 221 papers were selected and wholly reviewed. They were evaluated with inclusion and exclusion criteria, with 18 articles being chosen. Conclusions: Fecal calprotectin is a reliable surrogate marker of endoscopic activity in IBD. However, there is a lack of consensus on delimiting a cut-off point and improving applicability and diagnostic accuracy. Colonoscopy remains the gold standard in all studies.

Introducción: La enfermedad inflamatoria intestinal es un conjunto de patologías entre las que están incluidas la colitis ulcerativa y la enfermedad de Crohn, las cuales tienen presentación similar. En la actualidad, el diagnóstico y seguimiento de dicha enfermedad se basa principalmente en estudios endoscópicos, pero este método difícilmente puede aplicarse a la monitorización periódica de la enfermedad al ser costoso, invasivo y con disponibilidad limitada. La calprotectina fecal cumple con ser ampliamente disponible, fácil de usar y de precio asequible, y actualmente es el biomarcador mejor caracterizado para el uso en esta patología. Metodología: Diseño de investigación tipo revisión sistemática de la literatura de validación de prueba diagnóstica. Se realizó una búsqueda en diferentes bases de datos y para la evaluación de la calidad metodológica se empleó la lista verificación QUADAS-2. Resultados: La búsqueda inicial para la selección de los artículos arrojó un total de 352.843 artículos publicados principalmente en PubMed seguido de Scopus y Science Direct. Después de múltiples filtros se logró elegir 221 artículos, los cuales se llevaron a revisión completa. Se valoraron con criterios de inclusión y exclusión, lo que determinó la elección final de 18 artículos. Conclusiones: La calprotectina fecal es un marcador sustituto fiable de la actividad endoscópica en la EII. Se evidencia la falta de consenso para delimitar un punto de corte y mejorar la aplicabilidad y la precisión diagnóstica. La colonoscopia sigue siendo en todos los estudios el estándar de oro.

Papel de la reparación muscular en el tratamiento de la incontinencia anal

La incontinencia anal (IA) tiene una alta prevalencia en la sociedad, aumenta con la edad, presenta elevados costes económicos y tiene un importante impacto negativo en la calidad de vida de los pacientes que la padecen. El tratamiento quirúrgico se reserva para aquellos pacientes que no responden a medidas conservadoras. Clásicamente, las técnicas de reparación muscular han jugado un papel principal en el tratamiento de la IA, sobre todo en aquellos casos en los que había un defecto del complejo esfinteriano, siendo la más extendida la esfinteroplastía solapante y reservando técnicas más complejas como la graciloplastía para casos con lesiones esfinterianas catastróficas. Otras técnicas como la reparación total del suelo pélvico se encuentran en desuso por sus pobres resultados.

Anal Incontinence (AI) is a prevalent disease, increases with aging, has high economic costs and a deep impact in the quality of life of the patients who suffer it. Surgical treatment is proposed in patients with no-response to medical therapy. Muscle repair techniques have been the main approach in AI, specially when there is a sphincteric damage. Overlapping sphincteroplasty is the most common technique and graciloplasty is used when there is a wide damage in sphinteric complex. Some other techniques such as postanal or total pelvic floor repair are not used any more because of their poor results.

Sampling reflex as a new manometric marker in the diagnosis of defecation disorders: systematic review

Introduction: Distension of the rectum wall and subsequent momentary relaxation of the internal anal sphincter (IAS) trigger a reflex called the rectoanal inhibitory reflex (RAIR). This same rectal distension causes a reflex contraction of the external anal sphincter (EAS), responsible for conscious continence called rectoanal excitatory reflex (RAER). This set of reflexes are named sampling reflex. Objectives: The sampling reflex is necessary to initiate defecation or flatulence. The objective of this study is to evaluate the sampling reflex and its practical applicability as a manometric marker of the main defecation disorders. Methodology: This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) items. The development method consisted of searching for articles in the research platforms BVS, PubMed, Cochrane Library, SciELO and ScienceDirect and for the selection of articles the Rayyan Platform was used. The articles resulting from the search strategies were added to the platform and five collaborators were invited for the blind selection. Finally, 6 articles were included in the final review. Results: An intact sampling reflex allows the individual to facilitate discrimination between flatus and stool and to choose whether to discharge or retain rectal contents. On the other hand, an impaired sampling reflex can predispose an individual to incontinence. Therefore, it was observed that patients with defecation disorders had an impaired sampling reflex, since it was found that constipated patients have incomplete opening of the IAS, lower amplitude of RAIR and increase of RAER. Most incontinent patients present a failure in the recruitment of the EAS, a decrease in the RAER and an increase in the RAIR, in duration and amplitude. (AU)

Functional outcomes and satisfaction rates of sacral nerve stimulation in the treatment of one and multiples pelvic floor dysfunctions

Objective: Few studies have addressed the use of sacral nerve stimulation (SNS) in the treatment of patients with multiple pelvic floor dysfunctions (PFD). So, we evaluated the functional outcomes and level of satisfaction with SNS in selected patients with one or multiples PFD. Methods: A prospective database was used to collect information on eligible patients treated for PFD with SNS, and severity of symptoms was assessed with scores and satisfaction rates by visual analogue scale (VAS) at baseline and by the end of follow-up. Results: We recruited 70 patients, 98.6% of whom responded positively during the evaluation period (Global Response Assessment ≥ 50% for at least one type of PFD), resulting in the implantation of a permanent SNS device. Additionally, 49 of the patients (71%) had a single PFD (fecal incontinence [FI] = 38; constipation/obstructed defecation syndrome [C/ODS] = 11), while 20 (29%) had more than one PFD (double incontinence/n = 12; double incontinence + C/ODS/n = 8). All scores improved significantly between baseline (pre-SNS) and the end of follow-up (post-SNS), as did VAS in all groups (single and multiple PFD). The pre-SNS scores were higher in patients with a single PFD, including FI (Cleveland clinic Florida incontinence score [CCF-FI]) and C/ODS (Cleveland clinic constipation score [C-CCF] and the Renzi ODS score). The pre-SNS impact of VAS scores was similar in all groups (single and multiple PFD), but the VAS (post-SNS) was significantly lower (better response) for FI alone compared with multiple PFD. Conclusion: The SNS technique is an effective and safe option for patients with one or more PFD refractory to conservative measures. Response was positive for at least two PFD, based on reduced correspondent scores and satisfaction rate. (AU)

Apendicolito libre postapendicectomía

El apendicolito libre postapendicectomía es una complicación rara que puede ocurrir como consecuencia de la salida del apendicolito del apéndice debido a una perforación previa o al no identificar el apendicolito. El fecalito generalmente se vuelve sintomático con el tiempo, debido a la formación de un absceso, obstrucción intestinal, trayecto fistuloso o inflamación del muñón apendicular. Se describen dos casos de apendicolito libre postapendicectomía. Caso 1: mujer de 23 años, que fue sometida a una apendicectomía un día antes, ingresó por emergencia por presentar dolor en el hipogastrio. En la tomografía computarizada (TC) se evidenció un apendicolito libre en la fosa iliaca derecha, y en la laparoscopía diagnóstica se observaron abscesos intraabdominales y un apendicolito libre en el muñón apendicular. Caso 2: varón de 77 años de edad, que fue operado de apendicitis aguda causada por apendicolitos, presentó distensión abdominal al sexto día del posoperatorio. La TC reveló obstrucción intestinal y la presencia de apendicolito libre a nivel de las interasas intestinales; en la reintervención quirúrgica se evidenció erosión del mesenterio por causa del apendicolito. En ambos casos, los pacientes evolucionaron favorablemente después de las reoperaciones. Se desconoce actualmente la incidencia del apendicolito libre después de una apendicectomía, pues se dispone de pocos datos en la literatura a nivel mundial. Por tal motivo es importante la presentación de estos casos, para poder ampliar la casuística y contribuir al conocimiento de los apendicolitos libres postapendicectomía. Asimismo, permite evidenciar sus complicaciones si no son removidos precozmente y cómo prevenirlos. Conclusión: los apendicolitos libres postapendicectomía deben extraerse precozmente para evitar complicaciones.

Dropped appendicolith following an appendectomy is a rare complication which may occur as a consequence of appendicolith expulsion from the appendix due to a previous perforation or failure to identify the appendicolith. A fecalith generally becomes symptomatic over time, as a result of abscess formation, intestinal obstruction, fistula tract or inflammation of the appendiceal stump. Two cases of dropped appendicolith following an appendectomy are described hereinbelow. Case 1: A 23-year-old female patient, who underwent an appendectomy the previous day, was admitted to the emergency room due to hypogastric pain. A computed tomography (CT) scan revealed a dropped appendicolith in the right iliac fossa, and a diagnostic laparoscopy showed intra-abdominal abscesses and a dropped appendicolith in the appendicular stump. Case 2: A 77-year-old male patient, who underwent surgery for acute appendicitis caused by appendicoliths, showed abdominal distension on the sixth postoperative day. The CT scan revealed intestinal obstruction and a dropped appendicolith at bowel loops. In the surgical reintervention, erosion of the mesentery caused by the appendicolith was evidenced. Both patients progressed after the reoperations. The incidence of dropped appendicolith following an appendectomy is currently unknown since few data are available in the literature worldwide. Therefore, it is important to present these cases to expand the casuistry, learn more about dropped appendicoliths following an appendectomy, demonstrate their complications if they are not removed early and show how to prevent them. In conclusion, dropped appendicoliths following an appendectomy must be removed early to avoid complications.

Clinical study of 19 cases of steroid-refractory gastrointestinal acute graft-versus-host disease after allogeneic hematopoietic stem cell transplantation with fecal microbiota transplantation / 中华血液学杂志

Objective: To investigate the clinical efficacy of fecal microbiota transplantation (FMT) for treating steroid-refractory gastrointestinal acute graft-versus-host disease (GI-aGVHD) . Methods: This analysis included 29 patients with hematology who developed steroid-refractory GI-aGVHD after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in Huaian Hospital Affiliated to Xuzhou Medical University from March 2017 to March 2022. Among them, 19 patients underwent FMT treatment (the FMT group) and 10 patients did not (the control group). The efficacy and safety of FMT were assessed, as well as the changes in intestinal microbiota abundance, lymphocyte subpopulation ratio, peripheral blood inflammatory cytokines, and GVHD biomarkers before and after FMT treatment. Results: ① Complete remission of clinical symptoms after FMT was achieved by 13 (68.4%) patients and 2 (20.0%) controls, with a statistically significant difference (P<0.05). Intestinal microbiota diversity increased and gradually recovered to normal levels after FMT and FMT-related infections did not occur. ②The proportion of CD3(+) and CD8(+) cells in the FMT group after treatment decreased compared with the control group, and the ratio of CD4(+), regulatory T cells (Treg), and CD4(+)/CD8(+) cells increased (all P< 0.05). The interleukin (IL) -6 concentration in the FMT group was lower than that in the control group [4.15 (1.91-5.71) ng/L vs 6.82 (2.40-8.91) ng/L, P=0.040], and the IL-10 concentration in the FMT group was higher than that in the control group [12.11 (5.69-20.36) ng/L vs 7.51 (4.10-9.58) ng/L, P=0.024]. Islet-derived protein 3α (REG3α) was significantly increased in patients with GI-aGVHD, and the REG3α level in the FMT group was lower than that in the control group after treatment [30.70 (10.50-105.00) μg/L vs 74.35 (33.50-139.50) μg/L, P=0.021]. Conclusion: FMT is a safe and effective method for the treatment of steroid-refractory GI-aGVHD by restoring intestinal microbiota diversity, regulating inflammatory cytokines, and upregulating Treg cells.

A preliminary study of fecal microbiota transplantation alleviating inhibition of radiation-induced hippocampal neurogenesis in mice / 中华放射肿瘤学杂志

Objective:To evaluate the effects of whole brain irradiation (WBI) and fecal microbiota transplantation (FMT) on hippocampal neurogenesis and the composition of gut microbiota in mice.Methods:Forty specific pathogen free ICR male mice (8-week-old, weighed 30 g) were divided into four groups by simple random sample method: control group (group C), radiation group (group R), group C+FMT and group R+FMT, 10 in each group. Animal models were established by WBI at a dose of 10 Gy by 4 MeV electron beam. In group C+FMT and group R+FMT, mice were gavaged with normal fecal bacteria suspension on day 2 post-irradiation, while those in group C and group R were gavaged with phosphate buffered saline as alternative. Hippocampal tissues and feces in four groups were collected on day 15 post-irradiation. 16S rRNA sequencing was used to detect the species and abundance of fecal flora. BrdU +/NeuN + immunofluorescence staining was performed to observe the neurogenesis in hippocampus of mice. Results:WBI and FMT had no effect on survival rate and body weight of mice. WBI induced the inhibition of hippocampal neurogenesis and flora disorder. The quantity of Bacteroideae and Rumen bacteria was increased by 28.6% and 102.9%, whereas that of Lactobacillus was significantly decreased by 70.6% ( P<0.05). FMT regulated the abundance of bacteria. The abundance of Enterobacteriaceae was significantly declined by 65.1% ( P=0.028), while that of Lactobacillus was increased by 58.2% ( P=0.015). FMT also promoted hippocampal neurogenesis to some extent after WBI. Conclusions:This preliminary study demonstrates that FMT alleviates the inhibition of hippocampal neurogenesis and flora disorder induced by WBI in mice. Ionizing radiation directly acting on the whole brain of mice indirectly disturbs the composition of gut microbiota, which in turn affects the degree of hippocampal neurogenesis in the brain of mice. There is a bidirectional interaction between gut microbiota and brain.

A multiomics comparative study on the intervention of fecal microbiota transplants of Fengshining on rheumatoid arthritis / 药学学报

The study aims to investigate the mechanism of Fengshining fecal microbiota transplants in the intervention of rheumatoid arthritis by ultra-performance liquid chromatography-quadrupole/electrostatic field obitrap high-resolution mass spectrometry (UHPLC-Q-Exactive Orbitrap-MS). All animal welfare and experimental procedures followed the regulations of the Medical Ethics Committee of Shanxi University of Chinese medicine. The rats were randomly divided into normal group, model group, fecal microbiota transplantation group and Tripterygium wilfordii polyglycoside group, and the collagen induced arthritis (CIA) was established. The changes of body weight and metatarpodal lesions of rats were evaluated. The serum of rats in each group was analyzed by liquid chromatography-mass spectrometry and metagenomic technology for differential metabolites and microflora. The protein expression levels of Toll-like receptors (TLR4), myeloid differentiation factor 88 (MyD88) and nuclear factor of kappa B (NF-κB p65) were detected by Western blot. A total of 13 different metabolites, including arachidonic acid, docosahexaenoic acid, 13S-hydroxyoctadecanodienoic acid and L-phenylalanine were screened from serum. Three metabolic pathways, including phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine metabolism and arachidonic acid metabolism were identified through pathway enrichment. Metagenomic analysis showed that the abundance of g_Bacteroides, g_Prevotella and p_Actinobacteria in CIA group was higher. The abundance of c_Clostridia, g_Akkermansia and s_Akkermansia_muciniphila in fecal microbiota transplantation group is higher. The hierarchical cluster heat map showed that Akkermansia was negatively correlated with L-phenylalanine; while positively correlated with docosahexaenoic acid. Prevotella was positively correlated with L-phenylalanine. Fecal microbiota transplantation group could significantly inhibit the expression of TLR4, MyD88 and p65 proteins in the synovium of rats (P < 0.01). The anti-rheumatoid arthritis effects of fecal microbiota transplantation group is closely related to the intervention of the metabolism of phenylalanine and arachidonic acid, through Akkermansia, Prevotella and other microorganisms, inhibition the TLR4/MyD88/NF-κB pathway.

Effect of Anchang Decoction on intestinal flora and fecal calcitonin in rats with severe ulcerative colitis / 国际中医中药杂志

Objective:To investigate the effects of Anchang Decoction on intestinal microflora and faecal calprotectin (FC) in rats with severe ulcerative colitis based on probiotics.Methods:Totally 50 rats were taken to prepare a model of severe ulcerative colitis. The rats who successfully modeled were divided into model group, Anchang Decoction low-, medium-, high-dosage groups, Lizhu Changle group, and mesalazine group, with 5 rats in each group. Another 6 rats were set and the blank group. Lizhu Changle group received Lizhu Changle suspension (containing 50 million live bacteria/ml) for gavage; Anchang Decoction low-, medium-, high-dosage groups received Anchang Decoction 1, 5, 10 ml/(kg·d) for gavage; Mesalazine group received Mesalazine suspension (10.5 mg/100 g) for gavage. Rats in the blank group and model group were gavaged with the same volume of normal saline for 7 days. Body mass and disease activity index (DAI) before and after administration were measured. 16s rDNA of lactobacillus and bifidobacterium in feces of rats was detected. FC content of rats was detected by ELISA.Results:Compared with the model group, the weight of rats in each administration group increased ( P<0.05), DAI score decreased ( P<0.05), and the level of calprotectin in feces decreased ( P<0.05), and there was no significant difference in the levels of lactobacillus and bifidobacterium in each administration group ( P>0.05). Conclusion:Anchang Decoction can improve the intestinal micro-ecology by regulating the level of calprotectin in rats with severe ulcerative colitis, thereby playing a therapeutic role.

Value of detection of peripheral blood miR-194 combined with fecal miR-143 in the clinical screening of colorectal cancer / 国际肿瘤学杂志

Objective:To explore and analyze the value of detection of peripheral blood miR-194 combined with fecal miR-143 in the clinical screening of colorectal cancer.Methods:A total of 83 patients diagnosed with colorectal cancer by pathological tissue admitted to Huangshi Hospital of Traditional Chinese Medicine of Hubei Province from October 2019 to October 2020 were selected as the observation group, and 50 healthy volunteers who underwent physical examinations during the same period were selected as the control group. The levels of miR-194 in peripheral blood and miR-143 in feces were detected by fluorescence quantitative PCR. The level difference between the two groups and their correlations with clinicopathological parameters of patients with colorectal cancer were analyzed. Receiver operating characteristic (ROC) curve was drawn based on peripheral blood miR-194 and fecal miR-143 to evaluate their value for clinical screening of colorectal cancer.Results:The level of miR-194 in peripheral blood of the observation group was significantly higher than that of the control group (1.91±0.34 vs. 0.76±0.23) , while the level of fecal miR-143 in the observation group being significantly lower than that of the control group (1.85±0.43 vs. 2.48±0.62) , with statistically significant differences ( t=21.16, P<0.001; t=6.91, P<0.001) . Age of patients with colorectal cancer ( t=0.83, P=0.408; t=1.17, P=0.244) , TNM stage ( t=1.03, P=0.307; t=0.11, P=0.909) , lymphatic metastasis ( t=0.37, P=0.711; t=1.85, P=0.068) , distant metastasis ( t=0.41, P=0.683; t=1.72, P=0.089) were not correlated with the levels of peripheral blood miR-194 and fecal miR-143. When the cut-off value of miR-194 in peripheral blood was 1.82, the area under the ROC curve for the diagnosis of colorectal cancer was 0.76, and the diagnostic sensitivity and specificity were 79.38% and 74.29%, respectively. When the cut-off value of fecal miR-143 was 2.16, the area under the ROC curve for the diagnosis of colorectal cancer was 0.71. At this time, the diagnostic sensitivity and specificity were 76.54% and 73.61%, respectively. The area under ROC curve of combined detection for colorectal cancer was 0.81, and the diagnostic sensitivity and specificity were 83.46% and 75.43%, respectively. Conclusion:Peripheral blood miR-194 is highly expressed in colorectal cancer patients, and fecal miR-143 is low in colorectal cancer patients. The combined detection of the two has a high sensitivity for early diagnosis of colorectal cancer, which can provide important reference basis for early diagnosis of colorectal cancer and has high clinical application value.

Preliminary study on the effect of fecal microbiota transplantation on neurobehavior and gut microbiota of offspring rats exposed to arsenic / 中华劳动卫生职业病杂志

Objective: To explore the effects of fecal microbiota transplantation (FMT) on neurobehavior and gut microbiota of arsenic-exposed offspring rats. Methods: In April 2021, Thirty-six SPF SD rats aged 8 weeks were seleted, rats were ranked by weight and divided into four groups according to randomized block design, namely control group, arsenic exposure group (As group) , arsenic+normal saline group (As+NaCl group) and As+FMT group, 6 females and 3 males in each group. Fecal microbiota fluid were provided by feces of rats in control group. Rats drank tap water containing 75 mg/L sodium arsenite for one week and then were caged together. The arsenic exposure was terminated until the pups were born. Female rats with vaginal plug were treated with fecal microbiota fluid via gavage during neurodevelopmental teratogenic window period. The volume of gavage was 1 ml/100 g with once every two days, for a total of three times. Weight alterations of offspring rats were recorded every week after weaning, and when offspring rats grew up for 6 weeks, Morris test and open field experiment was used to observe learning and memory abilities, as well as neurobehavioral performance of autonomous exploration and tension, respectively. 16S rDNA sequencing technology was used to detect microbiota diversities in fecal samples of rats in As group and As+FMT group. Results: Compared with the control group, the ratio of swimming distance and staying time in the target quadrant and the times of crossing the platform of rats in As group decreased significantly, and the motor distance, times entering central zone and the number of grid crossing of rats decreased significantly (P<0.05) . Compared with As group, the ratio of swimming distance in target quadrant, the motor distance in central zone and times entering central zone of rats in As+FMT group were evidently increased (P<0.05) . The analysis of fecal microbiota diversities showed that, at the phyla level, the relative abundance of Bacteroidetes in feces of rats in As+FMT group was higher than that in As group (68.34% vs 60.55%) , while the relative abundance of Firmicutes was lower than that in As group (28.02% vs 33.48%) . At the genus level, the relative abundance of Prevotella in As+FMT group was significantly higher than that in As group, becoming the dominant genus (42.08% vs 21.78%) . Additionally, compared with As group, a total of 22 genus were increased with 21 decreased genus in As+FMT group (P<0.05) . LEfSe analysis showed that dominant genuses in As+FMT group were Prevotella and UCG_005, and their relative abundance was significantly higher than that of As group (P<0.05) . Conclusion: FMT may alleviate the impaired learning and memory ability and anxiety like behavior of the offspring rats exposed to arsenic, and improve the disrupted gut microbiota.

Dryness-alleviating effect of processed Aurantii Fructus from Lingnan based on correlation of fecal metabolomics and dryness / 中国中药杂志

With the approach of untargeted metabolomics and correlation analysis, this study aimed to explore the mechanism of Aurantii Fructus from Lingnan region in alleviating dryness by analyzing the different effects of raw Aurantii Fructus(RAF) and processed Aurantii Fructus(PAF) on fecal endogenous metabolism in normal rats. Eighteen Sprague-Dawley(SD) rats were randomly divided into a control group(C), an RAF group(10 g·kg~(-1)), and a PAF group(10 g·kg~(-1)). After seven days of administration, the effects of RAF and PAF on dryness-related indexes were compared, including water intake, fecal water content, salivary secretion, the expression of AQP5, VIP, and 5-HT in the submandibular gland, as well as the expression of AQP3, VIP, and 5-HT in the colon. The fecal samples in each group were determined by LC-MS. Multivariate statistical analysis and Pearson correlation coefficient were used for screening the differential metabolites and metabolic pathways in alleviating dryness of RAF. The results indicated that both RAF and PAF showed certain dryness, and the dryness of RAF was more significant. Moreover, PAF could alleviate dryness of RAF to a certain extent by reducing the water intake, fecal water content, and the expression of AQP3, VIP, and 5-HT in the colon and increasing the salivary secretion and the levels of AQP5, VIP, and 5-HT in the submandibular gland. According to the analysis of fecal metabolomics, 99 and 58 metabolites related to dryness were found in RAF and PAF respectively, where 16 of them played an important role in alleviating dryness of RAF. Pathway analysis revealed that the mechanism of PAF in alleviating dryness of RAF was presumably related to the regulation of riboflavin metabolism, purine metabolism, arginine biosynthesis, pyrimidine metabolism, alanine metabolism, aspartate metabolism, glutamate metabolism, and retinol metabolism pathways. This study suggested that PAF might alleviate dryness of RAF by affecting the metabolic levels of the body, which provides a new basis for further clarifying the processing mechanism of PAF.

Guijiajiao (Colla Carapacis et Plastri, CCP) prevents male infertility via gut microbiota modulation / 中国天然药物

Male infertility is a significant cause of psychosocial and marital distress in approximately 50% of couples who are unable to conceive, with male factors being the underlying cause. Guijiajiao (Colla Carapacis et Plastri, CCP) is a Traditional Chinese Medicine commonly used to treat male infertility. The present study aimed to investigate the potential mechanisms underlying the preventive effects of CCP on male infertility. An infertile male rat model was established using cyclophosphamide (CTX), and CCP was administered for both treatment and prevention. Fecal microbiota transplantation (FMT) was also performed to explore the role of gut microbiota in the CCP-mediated prevention of male infertility in rats. Sperm motility and concentration were determined using a semi-automatic sperm classification analyzer. Subsequently, histopathological analysis using HE staining was performed to examine the changes in the small intestine and testis. Moreover, the serum levels of lipopolysaccharide (LPS) and testosterone were measured by ELISA. In addition, immunohistochemistry was conducted to detect CD3 expression in the small intestine, while RT-qPCR was employed to assess the expressions of interleukin-1 beta (IL-1β), cluster of differentiation 3 (CD3), Monocyte chemoattractant protein-1 (MCP-1), and C-X-C motif chemokine ligand 10 (CXCL-10) in the small intestine and epididymis. Finally, gut microbiota was analyzed by 16S rRNA sequencing. CCP improved sperm motility, number, and concentration in CTX-induced infertile male rats. CCP increased the serum testosterone level, inhibited the immune cell infiltration of the intestinal lamina propria, and promoted the aggregation of CD3+ T cells in CTX-induced male infertility rats. CCP also inhibited the expressions of MCP-1, CXCL-10, and IL-1β in the epididymis of male infertility rats. At the genus level, CTX led to a reduction in the abundance of Lactobacillus, Clostridia_UCG.014, and Romboutsia in the intestinal tract of rats. In contrast, CCP decreased the abundance of Ruminococcus and increased the abundance of Romboutsia in infertile male rats. Additionally, FMT experiments proved that the gut microbiota of CCP-treated rats facilitated testicular tissue recovery and spermatogenesis while also reducing the serum LPS level in infertile male rats. CCP improves the spermatogenic ability of infertile male rats by restoring gut microbiota diversity and inhibiting epididymal inflammation.

Connotation of distal bleeding based on modern pathophysiological mechanism and application of Huangtu Decoction for acute coronary syndrome complicated with acute upper gastrointestinal hemorrhage in critical care medicine / 中国中药杂志

Huangtu Decoction, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, is used to treat distal bleeding. It is mainly treated for the syndrome of failing to control blood with spleen-yang deficiency. The connotation of distal bleeding is more extensive, including not only upper gastrointestinal bleeding in the traditional sense such as peptic ulcer bleeding, gastrointestinal tumors, gastric mucosal lesions, vascular dysplasia, esophagogastric variceal bleeding, and pancreatic and biliary tract injury, but also other anorectal diseases such as part colon and rectal cancer swelling or polyps, hemorrhoids, and anal fissure and other parts of bleeding such as epistaxis, thrombocytopenia, functional uterine bleeding, threatened abortion, and unexplained hematuria. Distal bleeding also involves syndromes of failing to keep part deficient and cold fluids in interior, such as nocturia, enuresis, clear nose, sweating, cold tears, and leucorrhea, and excessive gastrointestinal bleeding caused by anti-plate and anticoagulant drugs, unexplained positive in the fecal occult blood test, and other modern clinical new problems. The indications of Huangtu Decoction include not only lower blood, defecation before blood, distant blood, hematemesis, epistaxis, and other diseases in traditional Chinese medicine, but also three types of clinical manifestations including bleeding, deficiency syndrome, and stagnant heat syndrome. In the clinic, Huangtu Decoction can be used to treat acute upper gastrointestinal bleeding, acute coronary syndrome complicated with acute upper gastrointestinal bleeding, bleeding events caused by excessive antiplatelet and anticoagulant drugs, unexplained positive in the fecal occult blood test, gastrointestinal tumor with bleeding, thrombocytopenia, and other acute and critical diseases. The dosage of Cooking Stove Earthkey, Rehmanniae Radix, and Asini Corii Colla in Huangtu Decoction is the key to hemostasis.
