RESUMO
Objective To investigate the clinicopathological features of recurrent and de novo focal segmental glomerulosclerosis (FSGS) after kidney transplantation. Methods Thirty-four recipients pathologically diagnosed with FSGS by renal allograft biopsy were enrolled in this clinical trial. According to the detection of primary diseases of renal allografts and circulating permeability factors, 34 recipients were divided into the recurrent FSGS group (n=12) and de novo FSGS group (n=22). The differences of clinical indexes and the degree of pathological injury of renal allografts were compared between two groups. Results There was no significant difference in the mesangial hyperplasia score, glomerulosclerosis rate, renal tubular atrophy score, interstitial fibrosis score and podocyte proliferation rate between two groups (all P > 0.05). In the recurrent FSGS group, segmental glomerulosclerosis rate of the recipients was 0.10 (0.08, 0.27), lower than 0.19 (0.13, 0.33) in the de novo FSGS group (P < 0.05). No significant difference was found in the incidence of antibody-mediated rejection, drug-induced renal tubular injury and BK virus infection between two groups (all P > 0.05). The incidence of T cell-mediated rejection in the recurrent FSGS group was 17%, lower than 55% in the de novo FSGS group (P < 0.05). Immunohistochemical staining showed that the infiltrating inflammatory cells in the renal allografts were mainly T lymphocytes. The positive rates of C4d deposition in peripheral capillaries between the recurrent and de novo FSGS groups were 33% (4/12) and 32% (7/22), with no significant difference (P > 0.05). Immunofluorescence results revealed IgM deposition in the segmental glomerulosclerosis area of renal allografts in most cases. Electron microscopy showed extensive fusion or segmental distribution of podocytes in the glomerulus of renal allografts. Conclusions The degree of renal functional injury and the incidence of T cell-mediated rejection in the recurrent FSGS group are lower than those in the de novo FSGS group. Comprehensive analysis of preoperative and postoperative clinical manifestations, laboratory testing and pathological examination of kidney transplant recipients contribute to early diagnosis and treatment of recurrent and de novo FSGS.
RESUMO
Background/Aims@#The aim of this study was to analyze the chronological changes in postoperative complications in surgical ulcerative colitis patients over the past decade in China and to investigate the potential parameters that contributed to the changes. @*Methods@#Ulcerative colitis patients who underwent surgery during 2008–2017 were retrospectively enrolled from 13 hospitals in China. Postoperative complications were compared among different operation years. Risk factors for complications were identified by logistic regression analysis. @*Results@#A total of 446 surgical ulcerative colitis patients were analyzed. Fewer short-term complications (24.8% vs. 41.0%, P=0.001) and more laparoscopic surgeries (66.4% vs. 25.0%, P<0.001) were found among patients who received surgery during 2014–2017 than 2008–2013. Logistic regression suggested that independent protective factors against short-term complications were a higher preoperative body mass index (odds ratio [OR], 0.870; 95% confidence interval [CI], 0.785–0.964; P=0.008), laparoscopic surgery (OR, 0.391; 95% CI, 0.217–0.705; P=0.002) and elective surgery (OR, 0.213; 95% CI, 0.067–0.675; P=0.009). The chronological decrease in short-term complications was associated with an increase in laparoscopic surgery. @*Conclusions@#Our data revealed a downward trend of short-term postoperative complications among surgical ulcerative colitis patients in China during the past decade, which may be due to the promotion of minimally invasive techniques among Chinese surgeons.
RESUMO
It was a retrospective study. The patients with type 2 diabetes mellitus (T2DM) who underwent renal biopsy in the Department of Nephrology, the First Affiliated Hospital of Xi'an Jiaotong University from 2015 to 2021 were enrolled to analyze the pathological and clinical manifestations of kidney. There were 483 patients enrolled, including 136 patients who had no history of diabetes mellitus, newly diagnosed as T2DM according to an oral glucose tolerance test. The age was (52.80±13.13) years old. There were 337 males (69.77%). Based on the renal biopsy, the patients were classified as diabetic kidney disease (DKD, 22.15%, 107/483), DKD+non-diabetic kidney disease (NDKD)(6.63%, 32/483), and NDKD (71.22%, 344/483). Membranous nephropathy was the most common pathology in patients with NDKD (40.41%, 139/344) and DKD+NDKD (34.38%, 11/32). In the 136 newly diagnosed T2DM patients, there were 3 patients (2.21%) with DKD, 2 patients (1.47%) with DKD+NDKD, and 131 patients with NDKD (96.32%). The proportions of DKD in patients with diabetes history ≤3 months, 3-12 months, 1-5 years, 5-10 years and ≥10 years were 10.53% (6/57), 25.00% (16/64), 26.53% (26/98), 41.56% (32/77) and 47.06% (24/51), respectively. The proportions of DKD+NDKD in patients with diabetes history ≤3 months, 3-12 months, 1-5 years, 5-10 years and ≥10 years were 3.51% (2/57), 3.13% (2/64), 10.20% (10/98), 9.09% (7/77) and 17.65% (9/51), respectively. Multivariate logistic regression analysis results showed that, the duration of diabetes history ( OR=1.130, 95% CI 1.057-1.208, P<0.001), diabetes retinopathy ( OR=12.185, 95% CI 5.331-27.849, P<0.001), urinary red blood cell count ( OR=0.987, 95% CI 0.974-0.999, P=0.039), glycosylated hemoglobin ( OR=1.482, 95% CI 1.119-1.961, P=0.006) as well as hemoglobin ( OR=0.973, 95% CI 0.957-0.990, P=0.001) were independently correlated with DKD. The proportions of DKD and DKD+NDKD increase with the prolongation of diabetes history. Membranous nephropathy is the most common pathology in NDKD and DKD+NDKD patients. Even in patients newly diagnosed with T2DM, it is necessary to screen for DKD. The duration of diabetes history, diabetes retinopathy, urinary red blood cell count, glycosylated hemoglobin and hemoglobin may be used to identify DKD from NDKD.
RESUMO
In the last decade, the development of clinical practice guidelines in China has grown rapidly. However, with regards to the guidelines that have been established in the past, few were of high quality and in line with international standards. The main reason for this was that many clinical experts were not familiar with the procedures and rules of clinical guidelines before established, which lowered the quality seriously. Clinical practice guidelines are based on a clinical problem that is distilled into populations, interventions, comparison and outcome (PICO). After comprehensive systematic review, recommendations are made through evidence grading and strength of recommendation system. In addition, other issues should be noted such as pros and cons of the recommendation for specific population, preferences and values of the population, cost-effectiveness, and the health care system. A high-quality guideline requires multidimensional thinking (from clinicians, patients and policy makers), the implementation of a standard procedure (to ensure guidelines scientifically sound, honest and transparent), as well as the collaboration of multiple organizations (including experts, methodologists and policy makers).

Colorectal cancer is a common malignancy of the digestive tract, and the gut microbiota is closely related to the occurrence and development of colorectal cancer. The intestinal florae mainly change the host intestinal immune environment and affect the function of the intes-tinal barrier by releasing toxins and producing metabolites to participate the occurrence and deve-lopment of colon cancer. The intestinal florae can be used as biomarkers for early screening and prognosis prediction for colorectal cancer. In addition, the intestinal florae can affect the efficacy of chemotherapy, radiotherapy and immunotherapy for colorectal cancer. The authors review the research progress of gut microbiota in occurrence and development, screening, prognosis prediction and treatment of colorectal cancer, and discuss the application prospects of gut microbiota in the prevention and treatment of colorectal cancer.
RESUMO
BACKGROUND@#The complement system plays an important role in the immune response to transplantation, and the diagnostic significance of peritubular capillary (PTC) C4d deposition (C4d+) in grafts is controversial. The study aimed to fully investigate the risk factors for PTC C4d+ and analyze its significance in biopsy pathology of kidney transplantation.@*METHODS@#This retrospective study included 124 cases of kidney transplant with graft biopsy and donor-specific antibody (DSA) testing from January 2017 to December 2019 in a single center. The effects of recipient pathological indicators, eplet mismatch (MM), and DSAs on PTC C4d+ were examined using univariate and multivariate logistic regression analyses.@*RESULTS@#In total, 35/124 (28%) were PTC C4d+, including 21 with antibody-mediated rejection (AMR), eight with renal tubular injury, three with T cell-mediated rejection, one with glomerular disease, and two others. Univariate analysis revealed that DSAs (P < 0.001), glomerulitis (P < 0.001), peritubular capillaritis (P < 0.001), and human leukocyte antigen (HLA) B eplet MM (P = 0.010) were the influencing factors of PTC C4d+. According to multivariate analysis, DSAs (odds ratio [OR]: 9.608, 95% confidence interval [CI]: 2.742-33.668, P < 0.001), glomerulitis (OR: 3.581, 95%CI: 1.246-10.289, P = 0.018), and HLA B eplet MM (OR: 1.166, 95%CI: 1.005-1.353, P = 0.042) were the independent risk factors for PTC C4d+. In receiver operating characteristic curve analysis, the area under the curve was increased to 0.831 for predicting PTC C4d+ when considering glomerulitis, DSAs, and HLA B eplet MM. The proportions of HLA I DSAs and PTC C4d+ in active antibody-mediated rejection were 12/17 and 15/17, respectively; the proportions of HLA class II DSAs and PTC C4d+ in chronic AMR were 8/12 and 7/12, respectively. Furthermore, the higher the PTC C4d+ score was, the more serious the urinary occult blood and proteinuria of recipients at the time of biopsy.@*CONCLUSIONS@#PTC C4d+ was mainly observed in AMR cases. DSAs, glomerulitis, and HLA B eplet MM are the independent risk factors for PTC C4d+.

Inflammatory bowel disease (IBD) has become a global disease with accelerating incidence worldwide in the 21st century while its accurate etiology remains unclear. In the past decade, gut microbiota dysbiosis has consistently been associated with IBD. Although many IBD-associated dysbiosis have not been proven to be a cause or an effect of IBD, it is often hypothesized that at least some of alteration in microbiome is protective or causative. In this article, we selectively reviewed the hypothesis supported by both association studies in human and pathogenesis studies in biological models. Specifically, we reviewed the potential protective bacterial pathways and species against IBD, as well as the potential causative bacterial pathways and species of IBD. We also reviewed the potential roles of some members of mycobiome and virome in IBD. Lastly, we covered the current status of therapeutic approaches targeting microbiome, which is a promising strategy to alleviate and cure this inflammatory disease.
RESUMO
Objective@#To evaluate the safety and effectiveness of a vaccine based on latent membrane protein 2 (LMP2) modified dendritic cells (DCs) that boosts specific responses of cytotoxic T lymphocytes (CTLs) to LMP2 before and after intradermal injection in patients with nasopharyngeal carcinoma (NPC).@*Methods@#DCs were derived from peripheral blood monocytes of patients with NPC. We prepared LMP2-DCs infected by recombinant adenovirus vector expressing LMP2 (rAd-LMP2). NPC patients were immunized with 2 × 10 @*Results@#We demonstrated that DCs derived from monocytes displayed typical DC morphologies; the expression of LMP2 in the LMP2-DCs vaccine was confirmed by immunocytochemical assay. Twenty-nine patients with NPC were enrolled in this clinical trial. The LMP2-DCs vaccine was well tolerated in all of the patients. Boosted responses to LMP2 peptide sub-pools were observed in 18 of the 29 patients with NPC. The follow-up data of 29 immunized patients from April, 2010 to April 2015 indicated a five-year survival rate of 94.4% in responders and 45.5% in non-responders.@*Conclusion@#In this pilot study, we demonstrated that the LMP2-DCs vaccine is safe and effective in patients with NPC. Specific CTLs responses to LMP2 play a certain role in controlling and preventing the recurrence and metastasis of NPC, which warrants further clinical testing.

<p><b>OBJECTIVE</b>To investigate the risk factors of early surgical intervention in Crohn's disease (CD) patients with spontaneous intra-abdominal abscess.</p><p><b>METHODS</b>Clinical data of 94 CD patients with spontaneous intra-abdominal abscess admitted to The Sixth Affiliated Hospital of Sun Yat-sen University between May 2008 and Dec 2015 were analyzed retrospectively. Univariate and multivariate analysis were applied to evaluate the early surgery risk of CD patients with spontaneous intra-abdominal abscess using logistic regression model.</p><p><b>RESULTS</b>A total of 94 eligible patients were identified from our registry, including 70 males and 24 females. The mean age at the diagnosis of CD and at development of abscess was 28.4 years and 30.4 years old, respectively. The median duration of CD between the diagnosis and development of an abscess was 3 years. According to the Montreal classification, L3 (ileocolonic) was the most common disease location (81.9%) in these patients. Most of the patients(76.6%) developed a single abscess, while multiple abscesses were detected in 22 patients(23.4%). Forty-four patients(46.8%) underwent surgery within 60 days after hospitalization due to spontaneous intra-abdominal abscess complicating CD. Multivariate logistic regression analysis revealed that history of abdominal surgery(OR=3.23, 95%CI:1.12 to 9.31, P=0.030), concomitant intestinal stenosis (OR=3.52, 95%CI:1.26 to 9.85, P=0.017) and concomitant intestinal fistula (OR=4.31, 95%CI:1.25 to 14.80, P=0.020) were the independent risk factors of early surgical intervention, while enteral nutrition (OR=0.18, 95%CI:0.05 to 0.62, P=0.007) was the independent protective factor.</p><p><b>CONCLUSIONS</b>Nearly half of CD patients with spontaneous intra-abdominal abscess will undergo early surgical intervention. Patients with history of abdominal surgery, concomitant intestinal stenosis and concomitant intestinal fistula have higher risk of early surgical intervention, and appropriate application of enteral nutrition may reduce the risk.</p>
