RESUMO
BACKGROUND: Aflatoxin B1 (AFB1 ) poses a severe threat to human and animal health. Countries worldwide have invested considerable manpower and material resources in degrading aflatoxins. Enzyme degradation is the most efficient and environmentally friendly approach for modifying aflatoxin into less toxic molecules. Catalase is commonly used as a detoxification agent to decrease the contamination levels of aflatoxins in animal feeds. This study aimed to obtain recombinant catalase via gene engineering and determined whether a recombinant catalase could degrade AFB1 . RESULTS: The catalase gene (KatA) from Pseudomonas aeruginosa was cloned and expressed in Escherichia coli, and the expression conditions of this recombinant catalase were optimized. The recombinant catalase was isolated and purified using Ni-chelating affinity chromatography, and its ability to degrade AFB1 was evaluated. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed that the expressed of catalase was approximately 55.6 kDa, which was subsequently purified using Ni-chelating affinity chromatography. The degradation rate of AFB1 by recombinant catalase in the presence of syringaldehyde was 38.79%. CONCLUSION: The degradation of AFB1 by a recombinant catalase has been reported for the first time. This study provides a new paradigm for the use of recombinant catalases in degrading AFB1 in food and feed. © 2022 Society of Chemical Industry.

RESUMO
Objective:To analyze the diagnostic value of high-frequency ultrasound combined with serum thyroid-stimulating hormone (TSH) / thyroglobulin (Tg) ratio for the benign and malignant lesions of thyroid nodules (TN).Methods:A retrospective analysis was made on the clinical data of 772 patients with TN admitted to Changxing County People′s Hospital from June 2020 to June 2021. All patients received high-frequency ultrasound examination and serum TSH detection, 320 patients (41.45%) received Tg detection to calculate the TSH/Tg ratio. According to the benign and malignant thyroid nodules, they were divided into benign group and malignant group based on the pathological results as the "gold standard". The ultrasonographic characteristics, serum TSH and Tg levels and TSH/Tg ratio of the two groups were compared, and the accuracy of high-frequency ultrasound, TSH/Tg ratio and the combination in the diagnosis of benign and malignant thyroid nodules were evaluated.Results:A total of 83 patients with thyroid nodules were diagnosed as malignant by pathological results. In the malignant group, the nodules were mostly irregular in shape, extremely low in internal echo, accompanied by calcification, aspect ratio ≥1 and enlarged cervical lymph nodes. The levels of TSH and Tg as well as the ratio of TSH/Tg in the malignant group were higher than those in the benign group (16.52 ± 4.49) mU/L vs. (6.75 ± 1.18) mU/L, (11.37 ± 3.16) kU/L vs. (8.14 ± 1.40) kU/L, 1.45 ± 0.76 vs. 0.83 ± 0.06, there were statistical differences( P<0.05). The sensitivity and accuracy of high-frequency ultrasound combined with TSH/Tg ratio in the diagnosis of benign and malignant thyroid nodules were 92.77%, 95.47%, and higher than those in the single diagnosis. Conclusions:The morphological high-frequency ultrasonography features of malignant thyroid nodules are mostly irregular, with extremely low internal echo, accompanied by calcification, aspect ratio ≥1 and cervical lymph node enlargement. TSH/Tg ratio is higher than that of benign thyroid nodules. The combination of high-frequency ultrasonography and TSH/Tg ratio can improve the diagnosis rate of thyroid cancer.

RESUMO
Objective:To establish a computer-aided design and 3D printing system for precise implantation of micro implant anchorage, and accurately calibrate the position and direction of micro implant implantation.Methods:A retrospective selection was conducted on 15 patients (30 in total) who underwent micro implant implantation surgery from the Department of Stomatology, the Affiliated Hospital of Jiangnan University from November 2019 to November 2021, including 6 males and 9 females, aged (17.1±6.3)years old. The preoperative patient was photographed with cone beam computed tomography (CBCT) and the collected DICOM data format was output. A 3D scan was performed on the patient′s preoperative analysis model to obtain the STL file of the model scan. The CBCT data and model data were fitted and matched using 3Shape Implant Studio software, and the thickness of the guide plate, the amount of undercut compensation, and the size of the key component collar were designed. The 3D printer was used for printing after resizing. Using the assist method to implant micro implants, CBCT was taken postoperatively to compare the preoperative design with the postoperative results.Results:After fitting the postoperative CBCT with the designed CBCT of the micro implant, it was found that the micro implant was consistent with the preoperative design, maintained a safe distance and parallel to the adjacent tooth root, and did not damage the maxillary sinus and other areas. No detachment of the micro implant anchorage was observed 1 or 3 months after surgery. The application of assisted micro implant anchorage 3D guide plate was reliable, with accurate implantation position and direction, and can be implanted in most parts of the oral cavity.Conclusions:The use of computer-aided design and 3D printing system to create an assistive micro implant anchorage 3D guide plate can accurately locate the position and direction of the micro implant, which is worthy of clinical promotion and application.

RESUMO
Abstract@#Transport of filter paper-dried blood spot samples is a critical procedure during the screening of neonatal inherited metabolic diseases, which is of great significance for the screening accuracy. In order to ensure the timing and safety of sample transport, the cold chain positioning system was initiated by Zhejiang Provincial Center for Quality Control of Neonatal Disease Screening since March 2015. Based on the framework of neonatal disease screening information management system, the function of the logistics transport management system was included in this positioning system, with aims to achieve the monitoring and tracking of sample transport processes through real-time positioning of the sample transport box via China Unicom 4G logistics card and global positioning system/BeiDou Navigation Satellite System. The samples are maintained in a transport environment at 2 to 8 °C via the temperature-controlled box made of 5 °C phase-changed cold-stored materials and general packet radio service (GPRS) temperature recorders. The mean pretest turnover duration reduced from 8.44 days to 5.03 days following introduction of the cold chain positioning system, and the percentage of timely sample delivery increased from 31.69% to 77.90%, while the withdrawal rate of unqualified samples reduced from 0.12% to 0.08%. The cold chain positioning system meets the requirements of transport of filter paper-dried blood spot samples, which has a high potential in screening of neonatal inherited metabolic diseases.

<p><b>OBJECTIVE</b>[corrected] To characterize the insulinotropic action of hippocampal cholinergic neurostimulating peptide (HCNP) and analyze the role of type 3 muscarinic receptor (M(3)R) pathway in the action of HCNP.</p><p><b>METHODS</b>INS-1 cells were incubated in routine RPMI 1640 medium (control group), RPMI 1640 supplemented with 50 pg/ml synthetic HCNP (HCNP group), or HCNP-containing medium with the addition of PMA 18 h prior to insulin release assay. The insulin levels in the medium was measured using radioimmunoassay following stimulation with different concentrations of glucose. Real-time quantitative PCR was used for detecting the gene expression of HCNP-pp, choline acetyltransferase (ChAT) and M(3)R in HCNP group and control group.</p><p><b>RESULTS</b>After stimulation with different concentrations of glucose (5.6 and 16.7 mmol/L), HCNP group showed significantly higher insulin levels than the control and HCNP+ PMA groups. Compared with those in the control group, the mRNA levels of HCNP-pp, ChAT, and M(3)R were all lowered in HCNP group.</p><p><b>CONCLUSION</b>HCNP can promote insulin release in INS-1 cells by increasing ChAT activity and activating M(3)R, and this effect is inhibited by PMA.</p>

<p><b>OBJECTIVE</b>To investigate the effect of liraglutide on the inflammatory cytokine interleukin-1β (IL-1β) and apoptotic factor caspase-3 expression in the pancreatic islets of OLETF rats with impaired glucose tolerance.</p><p><b>METHODS</b>Twelve-week-old OLETF rats were randomized into 4 groups and received intraperitoneal injections of saline or liraglutide at 50, 100, or 200 µg/kg twice daily for 12 weeks. Eight LETO rats served as the normal control group and received saline injection. After the treatments, the rats were examined for fasting and 30 min plasma insulin during OGTT test, and the expression levels of IL-1β and caspase-3 mRNA and protein in the pancreatic islets were detected by real-time PCR and Western blotting, respectively.</p><p><b>RESULTS</b>Compared with the saline group, liraglutide significantly decreased the expressions of IL-1β and caspase-3 mRNA and protein, and significantly improved the blood glucose, islet β function and early-phase insulin secretion index in OLETF rats.</p><p><b>CONCLUSIONS</b>Liraglutide can improve islet function and glucose metabolism partially by inhibiting islet IL-1β expression to delay or prevent the development of diabetes in OLETF rats.</p>
