Effects of cellulase treatment on properties of lignocellulose-based biochar.

As the most abundant renewable carbon source, lignocellulose holds potential as a raw material for biofuels and biochar. The components required for biofuel production differ from those for biochar, so combining processes can reduce costs. Biofuel preparation necessitates cellulase treatment of lignocellulose. This study examines the effects of various enzyme treatment conditions (dosage, time, temperature) on lignocellulose, focusing on the properties of biochar derived from it (BC-SR). A mathematical model was constructed to study the relationship between enzyme treatment conditions and BC-SR properties. BC-SR exhibited high adsorption selectivity for bisphenol A and outperformed untreated biochar in fixed-bed column experiments, demonstrating greater removal efficiency and structural integrity. This study provides insights into the impact of enzymatic treatment on biochar and offers a cost-effective method for producing stable, efficient biochar. Additionally, a highly persistent biochar can enter the carbon trading market as a carbon-neutral technology, further realizing economic and environmental benefits.

Impact of hyperglycemia on tuberculosis treatment outcomes: a cohort study.

Hyperglycemia is prevalent and closely associated with pulmonary tuberculosis (PTB). This study aimed to investigate the effects of hyperglycemia on the outcomes of PTB treatment. This study comprised 791 patients with PTB in total. Patients with fasting plasma glucose levels of ≥ 6.1 mmol/L were diagnosed with hyperglycemia. Anthropometric and baseline demographic data were also collected. The treatment response was assessed based on clinical symptoms (sputum production, cough, chest pain, fever, hemoptysis, night sweats, loss of appetite, and fatigue), sputum smear, chest computed tomography (CT), and adverse gastrointestinal responses (vomiting, nausea, abdominal distension, diarrhea, and constipation). A generalized estimating equation (GEE) was used to evaluate these relationships. Hyperglycemia affected 266 (33.6%) of the 791 patients with PTB. In GEE analyses, patients with hyperglycemia exhibited a greater incidence of elevated tuberculosis (TB) scores (odds ratio (OR) 1.569; 95% CI 1.040-2.369), cough (OR 1.332; 95% CI 1.050-1.690), and night sweats (OR 1.694; 95% CI 1.288-2.335). Hyperglycemia was linked with a higher risk of positive sputum smears (OR 1.941; 95% CI 1.382-2.727). During therapy, hyperglycemia was also associated with an increased incidence of vomiting (OR 2.738; 95% CI 1.041-7.198), abdominal distension (OR 2.230; 95% CI 1.193-4.171), and constipation (OR 2.372; 95% CI 1.442-3.902). However, the CT results indicated that hyperglycemia did not affect pulmonary lesions in patients with TB. Patients with TB and hyperglycemia are at a higher risk of severe clinical manifestations, positive sputum smears, and adverse gastrointestinal effects and, therefore, the special situation of hyperglycemic patients should be considered in the prevention and treatment of TB.

Lanthanum nitrate demonstrated no genotoxicity in the conducted tests.

Given the widespread applications in industrial and agricultural production, the health effects of rare earth elements (REEs) have garnered public attention, and the genotoxicity of REEs remains unclear. In this study, we evaluated the genetic effects of lanthanum nitrate, a typical representative of REEs, with guideline-compliant in vivo and in vitro methods. Genotoxicity assays, including the Ames test, comet assay, mice bone marrow erythrocyte micronucleus test, spermatogonial chromosomal aberration test, and sperm malformation assay were conducted to assess mutagenicity, chromosomal damage, DNA damage, and sperm malformation. In the Ames test, no statistically significant increase in bacterial reverse mutation frequencies was found as compared with the negative control. Mice exposed to lanthanum nitrate did not exhibit a statistically significant increase in bone marrow erythrocyte micronucleus frequencies, spermatogonial chromosomal aberration frequencies, or sperm malformation frequencies compared to the negative control (P > 0.05). Additionally, after a 24-h treatment with lanthanum nitrate at concentrations of 1.25, 5, and 20 µg/ml, no cytotoxicity was observed in CHL cells. Furthermore, the comet assay results indicate no significant DNA damage was observed even after exposure to high doses of lanthanum nitrate (20 µg/ml). In conclusion, our findings suggest that lanthanum nitrate does not exhibit genotoxicity.

Study on the Expression and Potential Function of LncRNA in Peripheral Blood of Patients with Ankylosing Spondylitis.

BACKGROUND: Ankylosing spondylitis (AS) is an autoimmune disease that has the characteristics of difficult early diagnosis and a high disability rate. OBJECTIVE: The objective of this study was to further explore the possible mechanism and potential function of lncRNA in AS. METHODS: We used lncRNA microarray technology to detect the expression of lncRNA and mRNA in patients with active AS, stable patients, and healthy controls (HC). Afterward, bioinformatics analysis was conducted on differentially expressed genes. Seven differentially expressed lncRNAs were screened out for real-time fluorescent quantitative PCR (RT-qPCR), combined with various clinical indicators for correlation analysis, and the receiver operating characteristic (ROC) curve was used to analyze the potential of lncRNA as a diagnostic marker for AS. RESULTS: The results showed that the expression levels of NR-037662 and ENST00000599316 in the AS subgroups were significantly higher than those in the HC group, while the expression levels of ENST00000577914 and ENST00000579003 were lower than those in the HC group. The expression levels of NR-003542 and ENST00000512051 in the ASA group were significantly higher than those in the ASS and HC groups, while NR-026756 was just the opposite. Spearman's correlation analysis showed that the expression level of NR-003542 was positively correlated with Bath Ankylosing Spondylitis Functional Index (BASFI), Erythrocyte Sedimentation Rate (ESR), and high sensitivity C-Reactive Protein (hsCRP). The expression level of NR-026756 was negatively correlated with the Bath Ankylosing Spine Inflammatory Disease Activity Index (BASDAI), BASFI, ESR, hsCRP, and globulin (GLOB). In addition, it was also found that the ROC curve analysis of the 4 lncRNAs between the AS group (ASA group and ASS group) and the HC group were statistically significant, and the area under the curve (AUC) of NR-037662, ENST00000599316, ENST00000577914, and ENST00000579003 was 0.804, 0.812, 0.706, and 0.698, respectively. CONCLUSION: It was found that these differentially expressed lncRNAs of AS may be involved in the occurrence and development of the disease. Among them, NR-037662, ENST00000599316, ENST00000577914, and ENST00000579003 might have the potential to become AS diagnostic molecular markers. Moreover, NR -003542, ENST00000512051, and NR-026756 might have the potential to be indicators of disease activity.

Application value of ultrasound elastography for screening of early pregnancy cervical insufficiency: a retrospective case-control study.

OBJECTIVE: This study aimed to investigate changes in the cervical strain rate (SR), cervical length (CL), and uterine artery blood flow parameters during early pregnancy in women with cervical insufficiency and evaluate the clinical efficacy of these markers for screening of cervical insufficiency in early pregnancy. METHODS: This retrospective study in 60 pregnant women with cervical insufficiency and 100 normal pregnant women was conducted between September 2021 and January 2023 and measured ultrasound parameters of the cervix during early pregnancy. The cervical SR, CL, and uterine artery resistance index (RI) were measured in both groups at 11-14 weeks of gestation. Strain elastography represented by the SR was used to assess the hardness of the internal and external cervical openings. RESULTS: During early pregnancy, the SR at the internal and external cervical openings were significantly higher in the cervical insufficiency group than those in the normal pregnancy group (SR I: 0.19 ± 0.018% vs. 0.16 ± 0.014%; SR E: 0.26 ± 0.028% vs. 0.24 ± 0.025%; p < .001). The CL was significantly shorter in the cervical insufficiency group than that measured in the normal pregnancy group (34.3 ± 2.9 mm vs. 35.2 ± 1.99 mm; p = .036), while cervical blood perfusion was also poorer in the cervical insufficiency group than that in the normal pregnancy group (uterine artery RI: 0.76 ± 0.07 vs. 0.74 ± 0.05; p = .048). Receiver operating characteristic (ROC) curve analysis showed that the optimal critical values for diagnosing cervical insufficiency were 0.17% for SR I, 0.25% for SR E, 33.8 mm for CL, and 0.78 for uterine artery RI. Of these parameters, the ROC curve for SR I had the largest area under the curve [AUC = 0.89 (p < .001)], with the highest sensitivity (78%) and specificity (82%). Multivariate logistic regression analysis demonstrated that the SR at the internal cervical opening (OR 17.47, 95% confidence interval (CI) 5.08-60.08; p < .001) and CL (OR 5.05, 95% CI 1.66-15.32; p = .004) still showed significant differences between the two groups. CONCLUSION: Cervical elastography is an effective tool for screening early pregnancy cervical insufficiency. The SR at the internal cervical opening is a valuable indicator for screening cervical insufficiency and has superior clinical efficacy for screening for this condition compared to that of CL and the uterine artery blood flow index.

Seasonal dynamics response mechanism of benthic microbial community to artificial reef habitats.

Artificial reefs (ARs) have been globally deployed to enhance and restore coastal resource and ecosystems. Microorganisms play an essential role in marine ecosystems, while the knowledge regarding the impact of ARs on microecology is still limited, particularly data concerning the response of benthic microbial community to AR habitats. In this study, the seasonal dynamics of benthic microbial community in AR and adjacent non-artificial reef (NAR) areas surrounding Xiaoshi Island were investigated with high-throughput sequencing technology. The results revealed that the diversity and structure of microbial community between AR and NAR both displayed pronounced seasonal dynamics. There was a greater influence of season factors on microbial communities than that of habitat type. The microbial communities in AR and NAR habitats were characterized by a limited number of abundant taxa (ranging from 5 to 12 ASVs) with high relative abundance (8.35-25.53%) and numerous rare taxa (from 5994 to 12412 ASVs) with low relative abundance (11.91%-24.91%). Proteobacteria, Bacteroidota and Desulfobacterota were the common predominant phyla, with the relative abundances ranging from 50.94% to 76.76%. A total of 52 biomarkers were discovered, with 15, 4, 6, and 27 biomarkers identified in spring, summer, autumn and winter, respectively. Co-occurrence network analysis indicated that AR displayed a more complex interaction pattern and higher susceptibility to external disturbances. Furthermore, the neutral model and ßNTI analyses revealed that the assembly of microbial communities in both AR and NAR is significantly influenced by stochastic processes. This study could provide valuable insights into the impact of ARs construction on the benthic ecosystems and would greatly facilitate the development and implementation of the future AR projects.

ObjectiveTo explore the interaction among root fungi of Stellaria dichotoma var. lanceolata， soil factors， and main components of medicinal materials in lithosol habitats. MethodHigh-throughput sequencing technology was employed to determine the fungal community of the root system of S. dichotoma var. lanceolata at different levels （bulk soil， rhizosphere soil， rhizoplane soil， and root interior） and the soil properties of the root system （bulk and rhizosphere）， and the relationship among the fungal community， soil properties， and the main components of medicinal materials was analyzed. ResultThe total phosphorus， available phosphorus， alkaline nitrogen， dissolved organic carbon， and soil water content in the rhizosphere soil of S. dichotoma var. lanceolata were slightly higher than those in the rhizosphere， but the difference was not significant. Ascomycota is the dominant phylum of root fungi in S. dichotoma var. lanceolata. In the progressive level of bulk-rhizosphere-rhizoplane-root interior system， although the fungal diversity gradually decreased， the abundance of Hypocreales， a new phylum （unclassified_ k_ Fungi）， Helotiales， and Natipusilales gradually increased， among which Hypocreales is the most important fungal group in the root system of S. dichotoma var. lanceolata. The structural equation model （SEM） shows that the physicochemical factors of the root-soil play an important regulatory role in the fungal community and the main components of medicinal herbs， with soil total nitrogen， alkaline nitrogen， soil water content， and pH being the main regulatory factors. Soil nitrogen content is the key to promoting the main components of the medicinal herbs， and Penicillium fungi are the key fungal group to regulate the main components of the medicinal herbs. ConclusionIt highlights that the physicochemical properties of the soil of S. dichotoma var. lanceolata play a crucial role in the fungal community and the components of medicinal materials. Hypocreales fungi in the root of S. dichotoma var. lanceolata were an important group， and Penicillium fungi had a certain role in mediating the components of medicinal materials.

Comparison of vault measurements by Scansys, Pentacam, CASIA and Arcscan after ICL implantation / 中华实验眼科杂志

Objective:To evaluate the consistency of the Chinese three-dimensional anterior visual field analysis system (Scansys), the anterior segment analyzer (Pentacam), the frequency-domain anterior segment optical coherence tomography system (CASIA SS-1000), and a new ultra-high frequency digital ultrasound scanning system (Arcscan Insight100) to measure central vault after implantable collamer lens (ICL) implantation in myopic eyes with crystalline lenses.Methods:A diagnostic test study was conducted.Fifty-six myopic patients (56 eyes) who underwent ICL V4c implantation from June to December 2019 were included.Scansys, Pentacam, CASIA and Arcscan were used to measure the central vault after surgery.The vault measurements were compared.Correlations between the measurements of the four instruments were analyzed using Pearson correlation analysis, and consistency comparisons were analyzed using the Bland-Altman method.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2021[13]). Written informed consent was obtained from each subject.Results:The central vault measurements by Scansys, Pentacam, CASIA and Arcscan were (481.8±191.6), (476.4±190.6), (619.3±207.5) and (534.0±221.2)μm, respectively, with a statistically significant overall difference ( F=143.301, P<0.001). The vault measurements by Scansys and Pentacam were significantly lower than CASIA and Arcscan, and Arcscan was lower than CASIA, with statistically significant differences (all at P<0.001). There were strong positive correlations in vault measurements between Arcscan and CASIA, Arcscan and Pentacam, Arcscan and Scansys, CASIA and Pentacam, CASIA and Scansys, Pentacam and Scansys ( r=0.982, 0.933, 0.931, 0.942, 0.941, 0.989; all at P<0.001). Intraclass correlation coefficients of vault measurements by Scansys, Pentacam, CASIA and Arcscan were 0.985, 0.975, 0.998, 0.992, respectively.The 95% limits of agreement of vault measurements differences were -170 to 0, 0 to 280, 0 to 280, -110 to 210, -100 to 220 μm, between CASIA and Arcscan, CASIA and Scansys, CASIA and Pentacam, Arcscan and Scansys, Arcscan and Pentacam, respectively, and the maximum absolute value of the difference was beyond the clinically acceptable range, showing poor agreement.The 95% limits of agreement of vault measurement difference was -60 to 50 μm between Scansys and Pentacam, showing a good agreement. Conclusions:The repeatability of the vault after ICL V4c implantation in myopic eyes measured by the four instruments is good.Among them, the vault measurements of Scansys and Pentacam are smaller, showing good consistency, and their results could be substituted for each other.The measurement of CASIA is the largest, followed by Arcscan, which have a large difference from each other, and their results can not be substituted for each other, which should be comprehensively analyzed with the actual situation in clinical work.

Objective:To analyze the changes of diagnosis and treatment before and after renal biopsy in adult patients with acute kidney disease (AKD), and to explore the value of renal biopsy in the diagnosis and treatment of AKD.Methods:It was a single-center retrospective observational study. The adult patients with AKD who underwent renal biopsy in the Department of Nephrology of the First Affiliated Hospital of Nanjing Medical University from January 1, 2017 to December 31, 2021 were enrolled. Demographic data, general clinical data, laboratory tests, and diagnosis and treatment data before and after renal biopsy were collected to analyze the concordance rate between clinical and pathological diagnoses, changes in treatment after renal biopsy, and bleeding complication.Results:A total of 575 patients diagnosed with AKD by renal biopsy were included in this study, with age of 51 (36, 63) years old and 359 males (62.4%). Among them, there were 293 patients (51.0%) of acute kidney injury, 348 patients (60.5%) of hypertension and 124 patients (21.6%) of diabetes. The peak serum creatinine was 272 (190, 477) μmol/L. The hemoglobin was 106 (86, 126) g/L. The 24-hour urine protein was 2.15 (0.79, 4.82) g. There were 347 patients (60.3%) of acute glomerular diseases, 136 patients (23.7%) of acute interstitial nephritis, 47 patients (8.2%) of thrombotic microangiopathy, and 45 patients (7.8%) of acute tubular necrosis. The most common types of acute glomerular diseases were IgA nephropathy and anti-neutrophil cytoplasmic antibody-associated glomerulonephritis, accounting for 22.3% (128/575) and 12.2% (70/575), respectively. The clinical diagnoses before renal biopsy were consistent with the renal histopathological diagnoses in 454 patients, with an accuracy rate of 79.0%. Following the renal biopsy, the treatment plan involving glucocorticoids or immunosuppressants was adjusted in 394 patients (68.5%). Significant post-biopsy bleeding occurred in 15 patients (2.6%), with 12 patients requiring blood transfusion and 1 patient requiring surgical intervention.Conclusions:Twenty-one clinical diagnoses do not match the pathological diagnoses in adult AKD patients, 68.5% of patients have changes in their treatment plans, and 2.6% of patients have significant hemorrhagic complications after renal biopsy. Clinicians need to carefully consider the benefits and risks and make individualized decisions about renal biopsy.

Discussion on the Pathogenesis and Treatment of Children Enuresis Based on the Theory "Kidney-Marrow-Brain" Axis and "Yin Heel Channel （阴跷脉）" / 中医杂志

Guided by the theory of "kidney generates marrow"， the study elaborates the viewpoint that the route of Yin Heel Channel （阴跷脉） is consistent with the "kidney-marrow-brain" axis from the perspective of the circulation of the meridians and the relationship between the zang-fu organs. Accordingly， it is believed that disease of Yin Heel Channel and dysfunction of the "kidney-marrow-brain" axis are the core pathogenesis of children enuresis， and it is elaborated from the following three major aspects， firstly， insufficient kidney essence， dysfunction of the "kidney-marrow-brain" axis， secondly， disease of Yin Heel Channel and deficiency and cold in lower jiao， and thirdly， disease of Yin Heel Channel and loss of nourishment of Chong Vessel. It is proposed to use the mode of "firstly needle， secondly moxibustion， and lastly consolidation" to treat children enuresis. Needle is to adjust yin and yang， warm yang and tonify kidney， and wake up the brain and open the orifices. The acupoints in Yin Heel Channel such as Zhaohai （KI 6）， Jiaoxin （KI 8） and confluence points of the eight extraordinary vessels such as Waiguan （TE 5）， Zulinqi （GB 41） are used， together with Baihui （GV 20）， Yintang （EX-HN 3）， Guanyuan （CV 4）， Qixue （KI 13）， Dazhong （KI 4）. Moxibustion is to reinforce healthy qi and warm yang， bank up the root and consolidate the original qi by moxibustion at Shenque （CV 8）， Mingmen （GV 4）， and Xuanshu （GV 5）. Consolidation is to use acupoints application to consolidate the therapeutic effect， and Guanyuan （CV 4） & Pangguangshu （BL 28）， Qihai （CV 6） & Zhishi （BL 52）， and Shenque （CV 8） & Ciliao （BL 32） are commonly used as the three groups of acupoints to warm the kidney and stop collapse， regulate and tonify the qi and blood.

Huaier alleviates acute pancreatitis in mice by reducing ROS-induced pyroptosis in acinar cells / 西安交通大学学报(医学版)

【Objective】 To investigate the therapeutic effect of Huaier on acute pancreatitis (AP) and its potential mechanism. 【Methods】 A mouse model of cerulean-induced AP was used to verify the therapeutic effect of Huaier in vivo. HE staining and immunohistochemical staining were used to evaluate the histopathological changes of the pancreas, and transmission electron microscopy was used to observe the pyroptosis morphology of the pancreas. In vitro, 266-6 cell line was used as the experimental carrier to verify the protective effect of Huaier on acinar cells. Electron microscopy and Western blotting were used to evaluate the pyroptosis level of acinar cells, and ROS fluorescence probe was used to detect the oxidative stress state of acinar cells. 【Results】 Huaier significantly alleviated the severity of AP in mice. HE staining of pancreas showed that necrosis and inflammatory cell infiltration were reduced, and the level of serum amylase was decreased. Immunohistochemical staining and Western blotting showed that Huaier effectively inhibited the expressions of pyroptosis-related molecules such as NLRP3 and GSDMD in pancreatic tissue. Electron microscopy showed that Huaier could reduce the pyroptosis level of pancreatic acinar cells under inflammatory state. In addition, the level of ROS in acinar cells was significantly reduced after the intervention of Huaier, and ROS-mediated pyroptosis of acinar cells could be effectively inhibited by Huaier. 【Conclusion】 Huaier can effectively reduce the severity of AP by inhibiting ROS-mediated pyroptosis of acinar cells.

Current Status and Challenges of Guarantee for Rare Disease Drugs / 罕见病研究

In the past few years, China has pushed forward the availability of diagnosis and treatment of rare diseases. However, only 5% of patients receive effective treatment in the world. In China, the difficulties in having access to drugs against rare disease is still one of the major problems in medical service and the main cause of patients complaints for " difficulties in getting treatment" and " difficulties in getting drugs". The availability of the medication for rare disease is a coordinating mechanism involving multiple such points in the chain as in research and development, production, circulation, usage, way of payment, technology innovation and so forth. It also relates to the actors in supply, demand, and policy decision-makers. The complexity is different from that of common drugs. This article provides a brief overview of the current status of availability policies of medication for rare diseases in China and in other countries, as well as the technology in drug development. In addition, the article points out the problems, challenges and expectations for future possibilities.
