Objective:To evaluate the role of NOD-like receptor 3 (NLRP3) inflammasome activation-mediated macrophage polarization in myocardial injury after ischemic stroke in diabetic mice.Methods:Wild-type C57BL/6J mice and NLRP3 -/- mice, aged 4-6 weeks, were fed a high fat diet combined with streptozotocin administration to develop the diabetic model. Twenty-four diabetic wild type C57BL/6J mice and 23 diabetic NLRP3 -/- mice were divided into wild type sham operation group (WT D-SHAM group, n=9) , wild type ischemic stroke group (WT D-MCAO group, n=15) , NLRP3 -/- sham operation group (NLRP3 -/-D-SHAM group, n=9) and NLRP3 -/- ischemic stroke group (NLRP3 -/-D-MCAO group, n=14). The ischemic stroke model was developed by middle cerebral artery occlusion in the animals anesthetized with isoflurane. Echocardiography and electrocardiography were carried out at 3, 7, 14 and 28 days after developing the model. Mice were sacrificed under deep anesthesia, and myocardial tissues were taken at 28 days after surgery for determination of the expression of macrophage marker F4/80 and M2 type macrophage marker CD206 mRNA (by real-time fluorescence quantitative polymerase chain reaction). Results:Compared with WT D-SHAM group, the cardiac output, mass of left ventricle and corrected mass of left ventricle were significantly decreased at 28 days after surgery, and QT interval and QTc interval were prolonged at 14 and 28 days after developing the model in WT D-MCAO group ( P<0.05). Compared with NLRP3 -/-D-SHAM group, the cardiac output, mass of left ventricle and corrected mass of left ventricle were significantly decreased, and QT interval and QTc interval were prolonged at 3 days after surgery in NLRP3 -/-D-MCAO group ( P<0.05). There was no significant difference in CD206 and F4/80 mRNA expression between WT D-SHAM group and WT D-MCAO group and between NLRP3 -/-D-SHAM group and NLRP3 -/-D-MCAO group ( P>0.05). Compared with WT D-MCAO group, the QT interval and QTC interval were significantly shortened at 14 and 28 days after developing the model, and the expression of F4/80 mRNA was down-regulated and the expression of CD206 mRNA was up-regulated at 28 days after developing the model in NLRP3 -/-D-MCAO group ( P<0.05). Conclusions:NLRP3 inflammasome activation-mediated polarization of macrophages to M2 phenotype is involved in myocardial injury after ischemic stroke in diabetic mice.

At present, conventional periodontal treatment cannot achieve complete and effective periodontal tissue regeneration. Cell sheet technology (CST) is a kind of cell transplantation method without scaffold material that can maintain complete extracellular matrix, important ion channels of cells, growth factor receptors, etc., and ensure the interaction between cells and the extracellular matrix. In this paper, the application and research progress of the cell sheet in the field of periodontal tissue regeneration are reviewed. Different types of seed cells can be prepared into monolayer cell sheet, multilayer cell sheet, cell sheet fragments and cell sheet polymers. Among them, the monalayer cell sheet is easily damaged and requires high deoperator; the multilayer cell sheet shows improved mechanical properties, but its thickness needs to be controlled to avoid cell necrosis. The cell sheet fragment can be used in the narrow space between the alveolar bone and root cementum to reduce the difficulty of operation and improve the mechanical properties of the cell sheet. Cell sheet polymers are three-dimensional structures that can provide strong mechanical support and improve the stability of the cell sheet, but the stability of their biological activity needs to be further improved. In methods for construction of the cell sheet, the antifibrosis and antiangiogenesis properties of the amniotic sheet have shown that this structure is suitable as the matrix of cell culture; the method of using a temperature-sensitive culture dish is simple and easy; continuous induction with vitamin C can retain some important proteins on the cell surface; and the magnetic tissue engineering method can increase cell adhesion and easily form a stable cell sheet. The above methods have their own characteristics. In clinical applications, monolayer cell sheet is mainly used for direct transplantation to the receiving site to construct periodontal tissue; multilayer cell sheet of the same or different species overlap and are then transplanted to the receiving site; and multilayer cell sheet of the same kind are wrapped with scaffold material and then transplanted to the receiving site to construct a three-dimensional structure. Overall, cell sheet technology has shown good potential in periodontal tissue regeneration.

ObjectiveTo investigate the transformation mechanism and content variation of saponins from Polygalae Radix before and after being boiled with licorice juice and water. MethodSimulated licorice juice boiled products and simulated water boiled products of onjisaponin B， onjisaponin Z， onjisaponin F， polygalasaponin ⅩⅩⅧ were prepared by simulated processing technology， and analyzed by ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Exactive Orbitrap/MS）. Then the contents of onjisaponin B， onjisaponin Z， onjisaponin F， polygalasaponin ⅩⅩⅧ and tenuifolin in Polygalae Radix， licorice-boiled Polygalae Radix and water-boiled Polygalae Radix were determined by UPLC-triple quadrupole tandem mass spectrometry（UPLC-QQQ-MS/MS）. ResultDuring the boiling process with licorice juice and water， onjisaponin B could be hydrolyzed to produce 4-methoxycinnamic acid， desacylsenegin Ⅲ， polygalasaponin ⅩⅩⅧ and tenuifolin， onjisaponin Z could be hydrolyzed to produce 3，4，5-trimethoxycinnamic acid， onjisaponin TF， polygalasaponin ⅩⅩⅧ and tenuifolin， onjisaponin F could be hydrolyzed to produce 3，4，5-trimethoxycinnamic acid， onjisaponin G， polygalasaponin ⅩⅩⅧ and tenuifolin， and polygalasaponin ⅩⅩⅧ was hydrolyzed to produce tenuifolin. After being boiled with licorice juice or water， the content of onjisaponin B decreased significantly（P<0.05， P<0.01）， but the contents of onjisaponin Z， onjisaponin F， polygalasaponin ⅩⅩⅧ and tenuifolin increased significantly（P<0.05， P<0.01） in Polygalae Radix. Compared with the water-boiled products， the contents of onjisaponin Z and tenuifolin increased significantly（P<0.05， P<0.01）， and the change of tenuifolin content was the most significant in the licorice-boiled products.However， there was no significant difference in the content of onjisaponin B， onjisaponin F and polygalasaponin ⅩⅩⅧ between the water-boiled products and the licorice-boiled products. ConclusionBeing boiled with licorice juice or water can hydrolyze onjisaponin B， onjisaponin Z， onjisaponin F and polygalasaponin ⅩⅩⅧ， and generate secondary glycosides and aglycones（organic acids） through deglycosylation， which leads to obvious changes in the contents of onjisaponins after Polygalae Radix being processed.It is inferred that licorice juice can promote the hydrolysis of some onjisaponins in Polygalae Radix to onjisaponin Z and tenuifolin.This study provides an experimental basis for revealing processing mechanism of Polygalae Radix.

Objective:To construct a real-time artificial intelligence (AI)-assisted endoscepic diagnosis system based on YOLO v3 algorithm, and to evaluate its ability of detecting focal gastric lesions in gastroscopy.Methods:A total of 5 488 white light gastroscopic images (2 733 images with gastric focal lesions and 2 755 images without gastric focal lesions) from June to November 2019 and videos of 92 cases (288 168 clear stomach frames) from May to June 2020 at the Digestive Endoscopy Center of Renmin Hospital of Wuhan University were retrospectively collected for AI System test. A total of 3 997 prospective consecutive patients undergoing gastroscopy at the Digestive Endoscopy Center of Renmin Hospital of Wuhan University from July 6, 2020 to November 27, 2020 and May 6, 2021 to August 2, 2021 were enrolled to assess the clinical applicability of AI System. When AI System recognized an abnormal lesion, it marked the lesion with a blue box as a warning. The ability to identify focal gastric lesions and the frequency and causes of false positives and false negatives of AI System were statistically analyzed.Results:In the image test set, the accuracy, the sensitivity, the specificity, the positive predictive value and the negative predictive value of AI System were 92.3% (5 064/5 488), 95.0% (2 597/2 733), 89.5% (2 467/ 2 755), 90.0% (2 597/2 885) and 94.8% (2 467/2 603), respectively. In the video test set, the accuracy, the sensitivity, the specificity, the positive predictive value and the negative predictive value of AI System were 95.4% (274 792/288 168), 95.2% (109 727/115 287), 95.5% (165 065/172 881), 93.4% (109 727/117 543) and 96.7% (165 065/170 625), respectively. In clinical application, the detection rate of local gastric lesions by AI System was 93.0% (6 830/7 344). A total of 514 focal gastric lesions were missed by AI System. The main reasons were punctate erosions (48.8%, 251/514), diminutive xanthomas (22.8%, 117/514) and diminutive polyps (21.4%, 110/514). The mean number of false positives per gastroscopy was 2 (1, 4), most of which were due to normal mucosa folds (50.2%, 5 635/11 225), bubbles and mucus (35.0%, 3 928/11 225), and liquid deposited in the fundus (9.1%, 1 021/11 225).Conclusion:The application of AI System can increase the detection rate of focal gastric lesions.
