RESUMEN
Titanium (Ti) and its alloys as bio-implants have excellent biocompatibilities and osteogenic properties after modification of chemical composition and topography via various methods. The corrosion resistance of these modified materials is of great importance for changing oral system, while few researches have reported this point. Recently, oxidative corrosion induced by cellular metabolites has been well concerned. In this study, we explored the corrosion behaviors of four common materials (commercially pure Ti, cp-Ti; Sandblasting and acid etching-modified Ti, Ti-SLA; nanowires-modified Ti, Ti-NW; and zinc-containing nanowires-modified Ti, Ti-NW-Zn) with excellent biocompatibilities and osteogenic capacities under the macrophages induced-oxidizing microenvironment. The results showed that the materials immersed into a high oxidizing environment were more vulnerable to corrode. Meanwhile, different surfaces also showed various corrosion susceptibilities under oxidizing condition. Samples embed with zinc element exhibited more excellent corrosion resistance compared with other three surfaces exposure to excessive H2O2. Besides, we found that zinc-decorated Ti surfaces inhibited the adhesion and proliferation of macrophages on its surface and induced the M2 states of macrophages to better healing and tissue reconstruction. Most importantly, zinc-decorated Ti surfaces markedly increased the expressions of antioxidant enzyme relative genes in macrophages. It improved the oxidation microenvironment around the materials and further protected their properties. In summary, our results demonstrated that Ti-NW-Zn surfaces not only provided excellent corrosion resistance properties, but also inhibited the adhesion of macrophages. These aspects were necessary for maintaining osseointegration capacity and enhancing the corrosion resistance of Ti in numerous medical applications, particularly in dentistry.

BACKGROUND: Fecal microbiota transplantation (FMT) is a promising therapeutic approach for treating Crohn's disease (CD). The new method of FMT, based on the automatic washing process, was named as washed microbiota transplantation (WMT). Most existing studies have focused on observing the clinical phenomena. However, the mechanism of action of FMT for the effective management of CD-particularly in-depth multi-omics analysis involving the metagenome, metatranscriptome, and metabolome-has not yet been reported. AIM: To assess the efficacy of WMT for CD and explore alterations in the microbiome and metabolome in response to WMT. METHODS: We conducted a prospective, open-label, single-center clinical study. Eleven CD patients underwent WMT. Their clinical responses (defined as a decrease in their CD Activity Index score of > 100 points) and their microbiome (metagenome, metatranscriptome) and metabolome profiles were evaluated three months after the procedure. RESULTS: Seven of the 11 patients (63.6%) showed an optimal clinical response three months post-WMT. Gut microbiome diversity significantly increased after WMT, consistent with improved clinical symptoms. Comparison of the metagenome and metatranscriptome analyses revealed consistent alterations in certain strains, such as Faecalibacterium prausnitzii, Roseburia intestinalis, and Escherichia coli. In addition, metabolomics analyses demonstrated that CD patients had elevated levels of various amino acids before treatment compared to the donors. However, levels of vital amino acids that may be associated with disease progression (e.g., L-glutamic acid, gamma-glutamyl-leucine, and prolyl-glutamine) were reduced after WMT. CONCLUSION: WMT demonstrated therapeutic efficacy in CD treatment, likely due to the effective reconstruction of the patient's microbiome. Multi-omics techniques can effectively help decipher the potential mechanisms of WMT in treating CD.

OBJECTIVES: Fecal microbiota transplantation (FMT) has been recommended for the treatment of recurrent Clostridioides difficile infection (CDI). We aimed to evaluate the therapeutic efficacy and safety of washed microbiota transplantation (WMT), a new method of FMT, for CDI across various medical settings. METHODS: This multicenter real-world cohort study included CDI patients undergoing WMT. The primary outcome was the clinical cure rate of CDI within 8 weeks after WMT. Secondary outcomes included the CDI recurrence rate and reduction in total abdominal symptom score (TASS) during the follow-up period. Adverse events related to WMT were recorded. RESULTS: Altogether 90.7% (49/54) of CDI patients achieved clinical cure after treated with WMT. The cure rate was 83.3% for cases with severe and complicated CDI (ScCDI) (n = 30) and 100% for non-ScCDI cases (n = 24) (P = 0.059). No difference was observed in the clinical cure rate between patients with first and recurrent CDI (91.9% vs 88.2%, P = 0.645). One week post-WMT, TASS showed a remarkable decrease compared to that at baseline (P < 0.001). Totally, 8.2% (4/49) of patients suffered CDI recurrence during the follow-up period. A WHO performance score of 4, age ≥65 years, higher TASS score, and higher Charlson comorbidity index score were potential risk factors for efficacy (P = 0.018, 0.03, 0.01, 0.034, respectively). Four (3.8%) transient adverse events related to WMT were observed. CONCLUSIONS: This study emphasizes the attractive value of WMT for CDI. Early WMT may be recommended for CDI, especially for those in serious condition or with complex comorbidities. TRIAL REGISTRATION: ClinicalTrials.gov, no. NCT03895593 (registered on 27 March 2019).

Peutz-Jeghers syndrome (PJS) is an autosomal-dominant inherited disorder characterized by mucocutaneous pigmentation, hamartomatous polyposis of the gastrointestinal tract, and an increased risk for the development of both gastrointestinal and extraintestinal malignancies. Germline mutation of the STK11 gene, which encodes a serine-threonine kinase, is responsible for PJS. We collected blood samples from a Chinese PJS family consisting of a total of four individuals (one male and three females) including one PJS patient. The whole coding region of STK11 was amplified by polymerase chain reaction and products analyzed by direct sequencing. Molecular analysis of the STK11 gene in this case of PJS revealed a substitution of thymine 217 for adenine (C.217T > A) in exon 1, resulting in a change of codon 73 from cysteine to serine (C73S). The point mutation was not found in normal individuals in this PJS family or in 100 control individuals. The results presented here enlarge the spectrum of mutations of the STK11 gene by identifying a de novo mutation in a PJS patient and further support the hypothesis that STK11 mutations are disease-causing mutations for PJS.

BACKGROUND: Transendoscopic enteral tubing (TET) has been used in China as a novel delivery route for fecal microbiota transplantation (FMT) into the whole colon with a high degree of patient satisfaction among adults. AIM: To explore the recognition and attitudes of FMT through TET in patients with inflammatory bowel disease (IBD). METHODS: An anonymous questionnaire, evaluating their awareness and attitudes toward FMT and TET was distributed among IBD patients in two provinces of Eastern and Southwestern China. Question formats included single-choice questions, multiple-choice questions and sorting questions. Patients who had not undergone FMT were mainly investigated for their cognition and acceptance of FMT and TET. Patients who had experience of FMT, the way they underwent FMT and acceptance of TET were the main interest. Then all the patients were asked whether they would recommend FMT and TET. This study also analyzed the preference of FMT delivery in IBD patients and the patient-related factors associated with it. RESULTS: A total of 620 eligible questionnaires were included in the analysis. The survey showed that 44.6% (228/511) of patients did not know that FMT is a therapeutic option in IBD, and 80.6% (412/511) of them did not know the concept of TET. More than half (63.2%, 323/511) of the participants stated that they would agree to undergo FMT through TET. Of the patients who underwent FMT via TET [62.4% (68/109)], the majority [95.6% (65/68)] of them were satisfied with TET. Patients who had undergone FMT and TET were more likely to recommend FMT than patients who had not (94.5% vs 86.3%, P = 0.018 and 98.5% vs 87.8%, P = 0.017). Patients' choice for the delivery way of FMT would be affected by the type of disease and whether the patient had the experience of FMT. When compared to patients without experience of FMT, Crohn's disease and ulcerative colitis patients who had experience of FMT preferred mid-gut TET (P < 0.001) and colonic TET (P < 0.001), respectively. CONCLUSION: Patients' experience of FMT through TET lead them to maintain a positive attitude towards FMT. The present findings highlighted the significance of patient education on FMT and TET.
RESUMEN
BACKGROUND: Colonic transendoscopic enteral tubing (TET) requires double cecal intubation, raising a common concern of how to save cecal intubation time and make the tube stable. We hypothesized that cap-assisted colonoscopy (CC) might reduce the second cecal intubation time and bring potential benefits during the TET procedure. AIM: To investigate if CC can decrease the second cecal intubation time compared with regular colonoscopy (RC). METHODS: This prospective multicenter, randomized controlled trial was performed at four centers. Subjects ≥ 7 years needing colonic TET were recruited from August 2018 to January 2020. All subjects were randomly assigned to two groups. The primary outcome was the second cecal intubation time. Secondary outcomes included success rate, insertion pain score, single clip fixation time, purpose and retention time of TET tube, length of TET tube inserted into the colon, and all procedure-related (serious) adverse events. RESULTS: A total of 331 subjects were randomized to the RC (n = 165) or CC (n = 166) group. The median time of the second cecal intubation was significantly shorter for CC than RC (2.2 min vs 2.8 min, P < 0.001). In patients with constipation, the median time of second cecal intubation in the CC group (n = 50) was shorter than that in the RC group (n = 43) (2.6 min vs 3.8 min, P = 0.004). However, no difference was observed in the CC (n = 42) and RC (n = 46) groups of ulcerative colitis patients (2.0 min vs 2.5 min, P = 0.152). The insertion pain score during the procedure in CC (n = 14) was lower than that in RC (n = 19) in unsedated colonoscopy (3.8 ± 1.7 vs 5.4 ± 1.9; P = 0.015). Multivariate analysis revealed that only CC (odds ratio [OR]: 2.250, 95% confidence interval [CI]: 1.161-4.360; P = 0.016) was an independent factor affecting the second cecal intubation time in difficult colonoscopy. CC did not affect the colonic TET tube's retention time and length of the tube inserted into the colon. Moreover, multivariate analysis found that only endoscopic clip number (OR: 2.201, 95%CI: 1.541-3.143; P < 0.001) was an independent factor affecting the retention time. Multiple regression analysis showed that height (OR: 1.144, 95%CI: 1.027-1.275; P = 0.014) was the only independent factor influencing the length of TET tube inserted into the colon in adults. CONCLUSION: CC for colonic TET procedure is a safe and less painful technique, which can reduce cecal intubation time.

BACKGROUND: This study sought to evaluate the risk factors for the development of colitis-associated neoplasia (CAN) in Chinese patients with inflammatory bowel disease (IBD). METHODS: IBD patients who developed CAN between 1999 and 2016 were identified from eight medical centers. In addition to initial pathology evaluation, a CAN diagnosis was confirmed by two expert pathologists. Patients with CAN (n = 29) were compared with non-CAN controls (n = 87). Matching was performed for gender and IBD type with a ratio of three controls to one subject. RESULTS: Of the 29 patients with CAN, 8 (27.6%) had colorectal cancer (CRC), 20 (69.0%) had a final diagnosis of low-grade dysplasia and 1 (3.4%) had high-grade dysplasia. Multivariate analysis revealed that an older age at the time of IBD diagnosis and a longer IBD duration were independent risk factors for the development of CAN, with odds ratios of 1.09 [95% confidence interval (CI): 1.04-1.14, P < 0.001] and 1.14 (95% CI: 1.03-1.27, P = 0.013), respectively. Comparison between IBD patients with CRC and those with dysplasia indicated that the former were older at the time of IBD diagnosis (P = 0.012) and had longer IBD durations (P = 0.019). CONCLUSIONS: Older age at the time of IBD diagnosis and longer IBD duration were found to be associated with the development of CAN in IBD patients.
RESUMEN
RATIONALE: Fecal microbiota transplantation (FMT) has been used in a wide variety of diseases. In this article, we reported a 46-year-old female with diabetic neuropathy (DN) achieved remission by the treatment of FMT. PATIENT CONCERNS: The patient with an 8-year history of diabetes and hypertension was admitted to hospital due to sensitive pain of her right thigh and poor blood glucose control. The traditional hypoglycemic and analgesic treatment were useless to her symptoms. DIAGNOSIS: Diabetic-induced neuropathy was considered. INTERVENTIONS: This patient received twice FMTs for 3 months. OUTCOMES: After twice FMTs, the clinical response of patient was pleasant. The glycemic control was improved, with a remarkable relief of the symptoms of painful DN in particular. No obvious adverse effects were observed during the FMTs and follow-up observation-testing. LESSONS: We proposed that FMT could be a promising treatment in patients with diabetes or diabetes-related complications like DN. FMT also appeared to be definitely safer and more tolerable than the pharmacologic treatment in patients with DN.

Fecal microbiota transplantation (FMT) is a promising strategy that involves reconstruction of gut microbiota. Recently, it has been considered as a treatment of Crohn's disease (CD) and certain neurological diseases. Here, to the best of our knowledge, we report the first case that used FMT to achieve remission of intestinal and neurological symptoms in a girl with CD and a 17-year history of epilepsy. During the 20 mo of follow-up, FMT has proved its efficacy in preventing relapse of seizures after withdrawing the antiepileptic drugs. Furthermore, this finding highlights the role of microbiota-gut-brain axis and inspires a novel treatment for epilepsy through remodeling gut microbiota.

AIM: To explore the role of transforming growth factor-beta1 (TGF-beta1)-smad signal transduction pathway in patients with hepatocellular carcinoma. METHODS: Thirty-six hepatocellular carcinoma specimens were obtained from Qidong Liver Cancer Institute and Department of Pathology of the Second Affiliated Hospital of Nanjing Medical University. All primary antibodies (polyclonal antibodies) to TGF-beta1, type II Transforming growth factor-beta receptor (TbetaR-II), nuclear factor-kappaB (NF-kappaB), CD34, smad4 and smad7,secondary antibodies and immunohistochemical kit were purchased from Zhongshan Biotechnology Limited Company (Beijing, China). The expressions of TGF-beta1, TbetaR-II, NF-kappaB, smad4 and smad7 proteins in 36 specimens of hepatocellular carcinoma (HCC) and its adjacent tissue were separately detected by immunohistochemistry to observe the relationship between TGF-beta1 and TbetaR-II, between NF-kappaB and TGF-beta1, between smad4 and smad7 and between TGF-beta1 or TbetaR-IIand microvessel density (MVD). MVD was determined by labelling the vessel endothelial cells with CD34. RESULTS: The expression of TGF-beta1, smad7 and MVD was higher in HCC tissue than in adjacent HCC tissue (P<0.01, P<0.05, P<0.01 respectively). The expression of TbetaR-IIand smad4 was lower in HCC tissue than in its adjacent tissue (P<0.01, P<0.05 respectively). The expression of TGF-beta1 protein and NF-kappaB protein was consistent in HCC tissue. The expression of TGF-beta1 and MVD was also consistent in HCC tissue. The expression of TbetaR-IIwas negatively correlated with that of MVD in HCC tissue. CONCLUSION: The expressions of TGF-beta1, TbetaR-II, NF-kappaB, smad4 and smad7 in HCC tissue, which are major up and down stream factors of TGF-beta1-smad signal transduction pathway , are abnormal. These factors are closely related with MVD and may play an important role in HCC angiogenesis. The inhibitory action of TGF-beta1 is weakened in hepatic carcinoma cells because of abnormality of TGF-beta1 receptors (such as TbetaR-II) and postreceptors (such as smad4 and smad7). NF-kappaB may cause activation and production of TGF-beta1.

AIM: To evaluate the methodology, feasibility, safety and efficacy of a novel method called cap-assisted endoscopic sclerotherapy (CAES) for internal hemorrhoids. METHODS: A pilot study on CAES for gradeâ Iâ to III internal hemorrhoids was performed. Colon and terminal ileum examination by colonoscopy was performed for all patients before starting CAES. Polypectomy and excision of anal papilla fibroma were performed if polyps or anal papilla fibroma were found and assessed to be suitable for resection under endoscopy. CAES was performed based on the requirement of the cap, endoscope, disposable endoscopic long injection needle, enough insufflated air and sclerosing agent. RESULTS: A total of 30 patients with gradeâ Iâ to III internal hemorrhoids was included. The follow-up was more than four weeks. No bleeding was observed after CAES. One (3.33%) patient claimed mild tenesmus within four days after CAES in that an endoscopist performed this procedure for the first time. One hundred percent of patients were satisfied with this novel procedure, especially for those patients who underwent CAES in conjunction with polypectomy or excision of anal papilla fibroma. CONCLUSION: CAES as a novel endoscopic sclerotherapy should be a convenient, safe and effective flexible endoscopic therapy for internal hemorrhoids.
RESUMEN
BACKGROUND: Vasculogenic mimicry (VM), a new pattern of tumor microcirculation system, has been proved to be important for tumor growth and progression and may be one of the causes of antiangiogenesis resistance. Matrix metalloproteinase-9 (MMP9) was shown to correlate with VM formation in some other cancers. However, the relationship between VM formation and MMP9 in renal cell carcinoma (RCC) has not been determined. METHODS: The VM formation and MMP9 expressions were analyzed by CD34/periodic acid-Schiff dual staining and immunohistochemistry in 119 RCC specimens. We used a well-established 3-dimention culture model to compare VM formation in 786-O, 769-P, and HK-2 cell lines in vitro. MMP9 expressions on either messenger RNA or protein levels were compared among the cell lines by quantitative polymerase chain reaction or Western blot. To determine further the relationship between MMP9 and VM in RCC, 786-O and 769-P were treated with specific MMP9 inhibitor or small interfering RNA. VM formation, cell migration, and invasion were subsequently assessed by 3-dimention culture, wound-healing, and transwell assays. RESULTS: Immunohistochemistry demonstrated both VM formation and MMP9 overexpression were positively associated with clinical staging, pathological grade, and metastasis (P<0.01). VM formation was closely correlated with MMP9 overexpression in RCC (r = 0.602, P<0.01). Lower MMP9 expression level was observed in normal kidney cell line HK-2, which was unable to form VM on Matrigel, whereas higher expression of MMP9 was found in VM-forming cancer cell lines 786-O and 769-P. Inhibition of MMP9 not only disrupted VM formation in 786-O and 769-P but also reduced cell migration and invasion. CONCLUSIONS: These results indicate an intimate relationship between MMP9 overexpression and VM formation in RCC. Treatments targeting VM formation by inhibiting the activity of MMP9 could be beneficial in RCC therapy.

AIM: To investigate the relationship between cholecystectomy and fatty liver disease (FLD) in a Chinese population. METHODS: A total of 32428 subjects who had voluntarily undergone annual health checkups in the Second Affiliated Hospital of Nanjing Medical University from January 2011 to May 2013 were included in this study. Basic data collection, physical examination, laboratory examination, and abdominal ultrasound examination were performed. RESULTS: Subjects undergoing cholecystectomy were associated with greater age, female sex, higher body mass index, and higher levels of systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol, and triglycerides. However, no significant differences were found in high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, alanine aminotransferase, aspartate aminotransferase, gamma-glutamyl transpeptidase, albumin, and serum uric acid. The overall prevalence of FLD diagnosed by ultrasonography was high at 38.4%. The prevalence of FLD was significantly higher for subjects who had undergone cholecystectomy (46.9%) than those who had not undergone cholecystectomy (38.1%; χ(2) test, P < 0.001). Cholecystectomy was positively associated with FLD (OR = 1.433, 95%CI: 1.259-1.631). However, after adjusting for possible factors associated with FLD, multivariate regression analysis showed that the association between cholecystectomy and FLD was not statistically significant (OR = 1.096; 95%CI: 0.939-1.279). CONCLUSION: According to our study results, cholecystectomy may not be a significant risk factor for FLD.

Eosinophilic gastroenteritis is a rare disease of unknown etiology. It is characterized by patchy or diffuse eosinophilic infiltration of the bowel wall to a variable depth and various gastrointestinal manifestations. We describe a case of severe eosinophilic gastroenteritis presenting as frequent bowel obstruction and diarrhea in a 35-year-old man. The patient was misdiagnosed and underwent surgery because of intestinal obstruction when he was first admitted to a local hospital. Then he was misdiagnosed as having Crohn's disease in another university teaching hospital. Finally, the patient asked for further treatment from our hospital because of the on-going clinical trial for treating refractory Crohn's disease by fecal microbiota transplantation. Physical examination revealed a slight distended abdomen with diffuse tenderness. Laboratory investigation showed the total number of normal leukocytes with neutrophilia as 90.5%, as well as eosinopenia, monocytopenia and lymphocytopenia. Barium radiography and sigmoidoscopy confirmed inflammatory stenosis of the sigmoid colon. We diagnosed the patient as having eosinophilic gastroenteritis by multi-examinations. The patient was treated by fecal microbiota transplantation combined with oral prednisone, and was free from gastrointestinal symptoms at the time when we reported his disease. This case highlights the importance of awareness of manifestations of a rare disease like eosinophilic gastroenteritis.

The concept of fecal microbiota transplantation (FMT) has been used in traditional Chinese medicine at least since the 4(th) century. Evidence from recent human studies strongly supports the link between intestinal bacteria and inflammatory bowel disease. We proposed that standardized FMT might be a promising rescue therapy for refractory inflammatory bowel disease. However, there were no reports of FMT used in patients with severe Crohn's disease (CD). Here, we report the successful treatment of standardized FMT as a rescue therapy for a case of refractory CD complicated with fistula, residual Barium sulfate and formation of intraperitoneal large inflammatory mass. As far as we know, this is the first case of severe CD treated using FMT through mid-gut.

Foreign body ingestion is a common emergency situation in children with one or a few objects having been ingested. Here we report our experience using endoscopic retrieval in a female centenarian with dyspnea and foreign bodies in the esophagus. She attempted suicide by swallowing 26 coins and two other foreign bodies. A gastroscope was used to remove all foreign bodies in the lower esophagus. In total, 26 coins, one ferrous ring and one cylindrical plastic object were retrieved. To our knowledge, this is the first clinical report on retrieval of so many foreign bodies in a single case.

AIM: To conduct a meta-analysis to estimate the determinants of the association between erosive esophagitis (EE) and body mass index (BMI). METHODS: We identified the studies using PubMed. Studies were selected for analysis based on certain inclusion and exclusion criteria. Data were extracted from each study on the basis of predefined items. Meta-analyses were performed to verify the risk factors, such as obesity and gender. RESULTS: Twenty-one studies were included in this systematic review. These studies demonstrated an association between increasing BMI and the presence of EE [95% confidence interval (CI): 1.35-1.88, overweight, odds ratio (OR) = 1.60, P value homogeneity = 0.003, 95% CI: 1.65-2.55, obese, OR = 2.05, P < 0.01]. The heterogeneity disappeared by stratifying for gender. No publication bias was observed in this meta-analysis by the Egger method. CONCLUSION: This analysis demonstrates a positive association between BMI and the presence of EE, especially in males. The risk seems to progressively increase with increasing weight.
