Mangrove wetland recovery enhances soil carbon sequestration capacity of soil aggregates and microbial network stability in southeastern China.

Mangrove wetlands are highly productive ecosystems in tropical and subtropical coastal zones, play crucial roles in water purification, biodiversity maintenance, and carbon sequestration. Recent years have seen the implementation of pond return initiatives, which have facilitated the gradual recovery of mangrove areas in China. However, the implications of these initiatives for soil aggregate stability, microbial community structure, and network interactions remain unclear. This study assesses the impacts of converting ponds to mangroves-both in natural and artificially restored settings-on soil aggregate stability and microbial networks at typical mangrove restoration sites along China's southeastern coast. Our observations confirmed our hypothesis that pond-to-mangrove conversions resulted in an increase in the proportion of large aggregates (>0.25 mm), improved soil aggregate structural stability, and increased carbon sequestration. However, mangrove recovery led to a decrease in the abundance and diversity of soil fungi communities. In terms of co-occurrence networks, naturally restored mangrove wetlands exhibited more nodes and edges. The naturally recovered mangrove wetlands demonstrated a higher level of community symbiosis compared to those that were manually restored. Conversely, bacterial networks showed a different pattern, with significant shifts in key taxa related to carbon sequestration functions. For instance, the proportion of bacterial Desulfobacterota and fungi Basidiomycota in natural recovery mangrove increased by 15.03 % and 7.82 %, respectively, compared with that in aquaculture ponds. Soil fungi and bacteria communities, as well as carbon sequestration by aggregates, were all positively correlated with soil total carbon content (P < 0.05). Both bacterial and fungal communities contributed to soil aggregate stability. Our study highlights the complex relationships between soil microbial communities, aggregate stability, and the carbon cycle before and after land-use changes. These findings underscore the potential benefits of restoring mangrove wetlands, as such efforts can enhance carbon storage capacity and significantly contribute to climate change mitigation.

A case report of interstitial pneumonia induced by vedolizumab in a patient with ulcerative colitis.

RATIONALE: The interstitial pneumonia (IP) linked to vedolizumab (VDZ) in patients with ulcerative colitis (UC) is rare. Prompt diagnosis and treatment can improve patient outcomes. PATIENT CONCERNS: A 39-year-old man with UC who received VDZ as sole therapy developed symptoms such as chest tightness, cough, and suffocation. DIAGNOSES: IP was confirmed through pulmonary function tests, chest computed tomography, and bronchoscopic biopsy. INTERVENTIONS: The patient was given methylprednisolone and VDZ cessation. OUTCOMES: The patient's symptoms improved and remained symptom-free after nearly 2 years. LESSONS: VDZ-induced IP should be considered when evaluating pulmonary infections in UC patients treated with VDZ.

Real-life effectiveness and safety of vedolizumab in moderate-to-severe ulcerative colitis: A single-center experience in Northern China.

Vedolizumab (VDZ), a monoclonal antibody to α4ß7 integrin, is available for patients with moderate-to-severe ulcerative colitis (UC). This study planned to assess the real-world effectiveness and safety of VDZ for UC patients in Northern China. We enrolled patients with moderate-to-severe UC who underwent VDZ induction therapy from March 2021 to November 2022 at the Affiliated Hospital of Qingdao University. The primary outcome was clinical remission at weeks 14 and 52 after the initial VDZ therapy. Overall adverse events and risk factors associated with loss of response (LOR) were also evaluated. Seventy-three UC patients receiving VDZ therapy were included in this study. The rates of clinical response, clinical remission, and steroid-free clinical remission were 69.9%, 39.7%, and 34.2% at week 14 and 90.5%, 66.7%, and 64.4% at week 52, respectively. The mucosal remission rates were 37.5% (18/48) at week 14 ±â€…8 and 27.3% (9/33) at week 52 ±â€…16, while only 2 and 3 patients achieved mucosal healing at weeks 14 ±â€…8 and 52 ±â€…16, respectively. Of the UC patients, 23.3% experienced adverse events associated with VDZ, most of which were mild and self-limiting. Until the last follow-up, 37 of 73 UC patients experienced LOR during the maintenance period. Patients with a higher ulcerative colitis endoscopic severity index (UCEIS), partial Mayo scores (PMS), or hemoglobin below 120 g/L at baseline were more likely to experience LOR after VDZ induction therapy. VDZ is an effective and safe agent for patients with moderate-to-severe UC in Northern China. A high baseline UCEIS, PMS, or hemoglobin < 120 g/L may be an independent risk factor for LOR during the maintenance period.

Association of diet and outdoor time with inflammatory bowel disease: a multicenter case-control study using propensity matching analysis in China.

Objective: To investigate the association between dietary and some other environmental factors and the risk of inflammatory bowel diseases (IBD) in Chinese population. Materials and methods: A multicenter case-control study was conducted involving 11 hospitals across China. A total of 1,230 subjects were enrolled consecutively, and diet and environmental factor questionnaires were collected. IBD patients were matched with healthy controls (HC) using propensity-score matching (PSM) at a 1:1 ratio with a caliper value of 0.02. Multivariate conditional logistic regression analyses were performed to evaluate the associations between diet, environmental factors, and IBD. Results: Moderate alcohol and milk consumption, as well as daily intake of fresh fruit, were protective factors for both Crohn's disease (CD) and ulcerative colitis (UC). Conversely, the consumption of eggs and chocolate increased the risk of IBD. Outdoor time for more than 25% of the day was a protective factor only for CD. In eastern regions of China, CD patients had higher egg consumption and less outdoor time, while UC patients consumed more chocolate. IBD patients from urban areas or with higher per capita monthly income consumed more fruit, eggs, and chocolate. Conclusions: This study reveals an association between specific foods, outdoor time, and the emergence of IBD in the Chinese population. The findings emphasize the importance of a balanced diet, sufficient outdoor time and activities, and tailored prevention strategies considering regional variations.

Effects of proton pump inhibitors on inflammatory bowel disease: An updated review.

Inflammatory bowel disease (IBD) is believed to be caused by various factors, including abnormalities in disease susceptibility genes, environmental factors, immune factors, and intestinal bacteria. Proton pump inhibitors (PPIs) are the primary drugs used to treat acid-related diseases. They are also commonly prescribed to patients with IBD. Recent studies have suggested a potential association between the use of certain medications, such as PPIs, and the occurrence and progression of IBD. In this review, we summarize the potential impact of PPIs on IBD and analyze the underlying mechanisms. Our findings may provide insights for conducting further investigations into the effects of PPIs on IBD and serve as an important reminder for physicians to exercise caution when prescribing PPIs to patients with IBD.

The coexistence of myosteatosis and the creatinine/cystatin C ratio are determinants of outcomes in cholangiocarcinoma patients undergoing curative surgery.

Background: Myosteatosis is a well-established predictor of poor prognosis in many types of cancer, and a decreased Creatinine/Cystatin C ratio (CCR) is a known indicator of unfavorable outcomes in patients with metabolic disorders and cancer. Despite this knowledge, the significance of concurrent CCR and myosteatosis in predicting the prognosis of patients with cholangiocarcinoma (CCA) who undergo radical surgery remains uncertain. Method: Data from 757 patients with cholangiocarcinoma who underwent the first radical resection in the Affiliated Hospital of Qingdao University from January 2017 to March 2022 were collected. According to the inclusion and exclusion criteria, 149 patients were finally included in the retrospective study cohort. Various clinicopathological, serological, and radiological data were collected at admission. Myosteatosis was evaluated using sliceOmatic software on computed tomography (CT) images. The study used receiver operating characteristic (ROC) curve analysis to determine the critical value of CCR, which predicts overall survival (OS) based on the Kaplan-Meier method. Univariate and multivariate Cox regression analyses were employed to identify the risk factors associated with OS and RFS confidently. Results: The group identified as the myosteatosis cohort consisted of 79 patients with an average age of 64.3 ± 7.8 years. The ROC curve analysis revealed an optimal critical CCR value of 10.834. A low CCR ≤ 10.834 and myosteatosis were found to be associated with poor OS and RFS outcomes (P = 0.022; P = 0.017; P = 0.038; P = 0.030 respectively). Moreover, patients with myosteatosis and a CCR ≤ 10.834 had the worst OS and RFS outcomes (P = 0.035; P = 0.027). Conclusion: After radical excision in CCA patients, the presence of myosteatosis and CCR had a negative correlation with prognosis. A more accurate prediction of OS and RFS was possible by combining CCR and myosteatosis, compared to CCR alone.

Characterization of the complete chloroplast genome sequence of Lycium qingshuiheense (Solanaceae).

Lycium qingshuiheense is a typical drought and salt-alkali-tolerant plant, which has been added to the new species of Lycium in recent years. Here, we first sequenced the complete chloroplast genome of L. qingshuiheense to investigate its evolutionary relationship within the family Solanaceae. Results suggested that the circular complete chloroplast genome of L. qingshuiheense was 154,945 bp in length, including a large single-copy (LSC) of 85,930 bp, a small single-copy (SSC) of 18,203 bp, and two inverted repeats (IRs) of 25,406 bp. The GC content accounts for 37.90% and annotated 131 genes, including 86 protein-coding genes, eight rRNA genes, and 37 tRNA genes. A neighbor-joining phylogenetic tree revealed that L. qingshuiheense was a sister species to L. ruthenicum. Our study provides a new insight into the systematic evolution of Lycium in the Solanaceae family.

The influence of sleep factors and dietary habits on the disease pattern of ulcerative colitis patients with long and short disease courses - a multicentre cross-sectional analysis.

BACKGROUND: Ulcerative colitis (UC) is a disease characterized by chronic relapsing-remitting inflammatory disorders and is associated with environmental changes. AIM: To explore the disease patterns of Chinese UC patients and to determine controllable related environmental factors. METHODS: This multicentre cross-sectional study was performed using a questionnaire survey. Data on clinical characteristics and environmental factors were collected. Patients with a disease course ≥5 years were defined as the long course group, and those with a disease course < 5 years were defined as the short course group. RESULTS: A total of 588 effective questionnaires were collected. The proportion of the chronic continuous pattern was the highest among patients with a long disease course (46.8%), and in patients with a short disease course, the proportion of the active to remission pattern was the highest (53.3%). In patients with a long disease course, a higher proportion of patients with adequate sleep was found in the active to remission pattern than in the chronic intermittent (72.1% vs. 43.3%, p = 0.008) and chronic continuous (72.1% vs. 52.4%, p = 0.016) patterns. In patients with a short disease course, the frequency of shellfish and shrimp was higher in the chronic continuous pattern group than in the active to remission pattern group (P = 0.001 and 0.017 respectively). CONCLUSIONS: For early diagnosis patients, dietary guidance should be actively carried out. With the prolongation of the disease course, attention should be given to the sleep quality of patients.

1.UC exhibits various disease patterns, which may be associated with differences in patient prognosis and treatment response.2.Environmental factors, especially sleep and dietary factors, correlated strongly with disease patterns, which varied in different disease courses.3.Early diagnosis patients should receive active dietary guidance, while patients with a prolonged disease course require attention to their sleep quality and appropriate drug interventions when necessary.

Clinical value of the Toronto inflammatory bowel disease global endoscopic reporting score in ulcerative colitis.

BACKGROUND: Endoscopic evaluation in diagnosing and managing ulcerative colitis (UC) is becoming increasingly important. Several endoscopic scoring systems have been established, including the Ulcerative Colitis Endoscopic Index of Severity (UCEIS) score and Mayo Endoscopic Subscore (MES). Furthermore, the Toronto Inflammatory Bowel Disease Global Endoscopic Reporting (TIGER) score for UC has recently been proposed; however, its clinical value remains unclear. AIM: To investigate the clinical value of the TIGER score in UC by comparing it with the UCEIS score and MES. METHODS: This retrospective study included 166 patients with UC who underwent total colonoscopy between January 2017 and March 2023 at the Affiliated Hospital of Qingdao University (Qingdao, China). We retrospectively analysed endoscopic scores, laboratory and clinical data, treatment, and readmissions within 1 year. Spearman's rank correlation coefficient, receiver operating characteristic curve, and univariate and multivariable logistic regression analyses were performed using IBM SPSS Statistics for Windows, version 26.0 (IBM Corp., Armonk, NY, United States) and GraphPad Prism version 9.0.0 for Windows (GraphPad Software, Boston, Massachusetts, United States). RESULTS: The TIGER score significantly correlated with the UCEIS score and MES (r = 0.721, 0.626, both P < 0.001), showed good differentiating values for clinical severity among mild, moderate, and severe UC [8 (4-112.75) vs 210 (109-219) vs 328 (219-426), all P < 0.001], and exhibited predictive value in diagnosing patients with severe UC [area under the curve (AUC) = 0.897, P < 0.001]. Additionally, the TIGER (r = 0.639, 0,551, 0.488, 0.376, all P < 0.001) and UCEIS scores (r = 0.622, 0,540, 0.494, and 0.375, all P < 0.001) showed stronger correlations with laboratory and clinical parameters, including C-reactive protein, erythrocyte sedimentation rate, length of hospitalisation, and hospitalisation costs, than MES (r = 0.509, 0,351, 0.339, and 0.270, all P < 0.001). The TIGER score showed the best predictability for patients' recent advanced treatment, including systemic corticosteroids, biologics, or immunomodulators (AUC = 0.848, P < 0.001) and 1-year readmission (AUC = 0.700, P < 0.001) compared with the UCEIS score (AUC = 0.762, P < 0.001; 0.627, P < 0.05) and MES (AUC = 0.684, P < 0.001; 0.578, P = 0.132). Furthermore, a TIGER score of ≥ 317 was identified as an independent risk factor for advanced UC treatment (P = 0.011). CONCLUSION: The TIGER score may be superior to the UCIES score and MES in improving the accuracy of clinical disease severity assessment, guiding therapeutic decision-making, and predicting short-term prognosis.
