This article was aimed to study the general reproductive toxicity in mice in order to give a better evalua-tion of the medicinal plant of pineapple leaves (A nanas comasus L). Adult male and female mice were orally admin-istered with pineapple leaves. And then, each of the male and female mice was put together in one cage for mating. The mating success females were fed continuously. The experimental observation was conducted in pregnancy, fetal development, as well as the offspring of mice. The results showed that in addition to a large dose of pineapple leaves (4 g·kg-1) of the parental male rats having a lower body weight, pineapple leaves did not significantly affect on other parameters. There were no significant effects on pregnant mice and their offspring of mice. It was concluded that the pineapple leaves did not influence the general reproductive function of mice apparently.

To improve spinosyn-producing strain and enhance spinosyns yield, we studied the effects of glycin concentration and the operational time, temperature and lysozyme concentration on protoplast preparation of Saccharopolyspora spinosa SP06081. We also studied different regeneration media and osmotic stabilizing agents. In addition, we compared the change of morphology and spinosyns yield of the regenerated strains. The results showed that the Saccharopolyspora spinosa SP06081 protoplast yield was the highest under these conditions: the collected mycelium from SP06081 grown in Tryptic Soy Broth (TSB) medium with 0.2% glycin for 48 h was treated by 0.1 mg/mL lysozyme at 28 degrees C for 20 min, then plated on the R2YE medium with sucrose as osmotic stabilizer, the number of regeneration protoplast was up to 10(8)/mL. The protoplast-regenerated strains exhibited changes in morphology and antibiotic production, 29.3% protoplast-regenerated strains was characterized by loose mycelium and abundant broken branches as did their parent. Among them, 58.2% strains presented the trend to positive variation in spinosad yield, with the highest spinosad yield of up to 582.0 mg/L, 85.6% higher than that of their parent. There is significant correlation between the morphological differentiation and antibiotic yield of the protoplast-regenerated strains from spinosyn-producing strain.

This paper provides an overview of EHRs, summarizes their current applications in palliative care, and proposes solutions to address issues in the use of EHRs in this field. The aim is to offer reference points for promoting the application of EHRs in palliative care in China.

Objective:To investigate the uncertainty level of caregivers of children with imperforate anus, and determine the influence factors.Methods:Two hundred and twenty-nine caregivers were enrolled from three tertiary children′s hospital in Eastern China. The caregivers completed the Perception of Uncertainty Scale, Parent Stigma Scale and Social Support Scale. The demographic information of caregivers and affected children were also collected during the survey.Results:The average score of uncertainty of caregivers was (72.58±14.06) points, and multiple analysis showed that education level, the acceptance level of disease, social support and stigma were independent determinants of uncertainty ( P<0.01), and these factors could account for 26.9% of the variance. Conclusions:The caregivers of children with imperforate anus experience a high level of uncertainty, especially those with low education level, share low acceptance level of disease, receive low social support and experience higher level of stigma.

Objective:To study the effect of atractylodes lactideⅠ,Ⅱand Ⅲ on the expression of cytokines by inducing M1 type macrophage model. Methods:Apoptotic macrophages were induced by sodium thioglycolate, and then the rat peritoneal inflammatory macrophages were purified by a differential adherence method. The expression of macrophage marker antigen (ED1) was identified by flow cytometry macrophages. Tumor necrosis factor ( TNF-α) , proinflammatory cytokines ( IL-1β) and interleukin-6 ( IL-6 ) were measured by ELISA in vitro. The levels of expression of arginase 1, inducible nitric oxide synthase (iNOS), inflammatory cytokines (IL-1β) chemokine (CCL22) and transforming growth factor (TGF-β) in inflammatory macrophages were determined by RT-PCR. Results:As for the purification of cultured rat inflammatory macrophage expressing ED1, atractylenolideⅠand Ⅲ could reduce the ex-pression levels of iNOS and IL-1βand increase the expression levels of arginase1 CCL22 and TGF-β. The release of inflammatory fac-tor IL-1β decreased, and the release levels of TGF-β and chemokines CCL22 were promoted(P<0. 05). Atropine lactoneⅠ and Ⅲ had significant inhibitory effects on TNF-α, IL-1β and IL-6 in macrophages(P<0. 05). Conclusion: Atractylodes lactone Ⅰand Ⅲ with anti-inflammatory activity can promote the expression of cytokines in inflammatory macrophages, while the change induced by at-ractylaxanthin Ⅱ is not obvious.

Objective:To explore the clinicopathological characteristics, immunophenotype, diagnosis and differential diagnosis of renal mucinous tubular and spindle cell carcinoma (MTSCC), and to explore the all-exon mutations, microsatellite stability and tumor mutational burden (TMB) in MTSCC cases.Methods:The data of 5 patients with MTSCC that were submitted to the Department of Pathology, First Affiliated Hospital of Soochow University, China from January 2008 to May 2020, were reviewed and analyzed. The whole exome sequencing (WES) was conducted in all patients, while 3 of them were subject to the analyses of microsatellite stability and TMB.Results:Among the 5 patients, 3 were males and 2 were females. They were 37-76 years old. The maximum diameter of the tumor was 3.5-6.0 cm. The borders of the tumors were well defined. Microscopically, MTSCC was characterized by tubular structure, spindle cell and mucinous stroma, and the nuclear grade of tumor cells was overall low. The average follow-up was 15 months, and no recurrence or metastasis was found. Immunohistochemistry showed that all 5 cases were positive for broad-spectrum cytokeratin (CKpan), cytokeratin (CK)7, CK19, vimentin, PAX8, and P504s (varying expression levels), and the Ki-67 positive index was low. The WES of 5 cases showed that NF2 and PTPN14 exhibited higher mutation rates, which were 3/5 and 2/5, respectively. The microsatellite stability analysis indicated that the 3 cases were all microsatellite stable, and the TMB analysis showed that the TMB of the 3 cases were all <9 mut/Mb.Conclusions:MTSCC is a unique, low-grade pleomorphic kidney tumor. The WES analyses suggest that NF2 and PTPN14 have a higher mutation rate, indicating that the occurrence and development of MTSCC may be closely related to the Hippo pathway. The analysis of microsatellite stability indicates that there is no significant relationship between microsatellite stability and MTSCC, and the TMB analysis suggests that MTSCC patients may not benefit from immunotherapy.

The aim of this study was to investigate the effects of high-intensity interval training(HIIT)on lipopolysaccharide(LPS)-induced septic myocardial injury in mice and the roles of NLRP3 inflammasome and macrophage M1 polarization in the process.C57BL/6 male mice were randomly divided into 4 groups:control(CON)group,LPS(L)group,HIIT+saline injection(E)group,and HIIT+LPS(EL)group.Six weeks of HIIT intervention was followed by intraperitoneal injection of LPS,and cardiac function indexes were measured by echocardiography 12 hours post the injection.Hematoxylin-eosin(HE)staining was used to evaluate the morphology and pathological characteristics of myocardium for assessing myocardial damage score;enzyme-linked immunosorbent assay(ELISA)was used to test the content of myocardial damage indicators(AST,CK-MB,LDH);RT-PCR was used to detect the relative mRNA levels of NLRP3 inflammasome(NLRP3,Caspase-1),atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),myeloperoxidase(MPO)and macrophage M1-associated inflammasome factors(IL-1β,TNF-α,IL-6);Western blot was applied to measure the protein expression of inducible nitric oxide synthase(iNOS)and apoptosis-associated speck-like protein containing a caspase recruitment domain(ASC)in cardiac tissues;immunofluorescence staining was used to detect the protein expression of NLRP3 inflammasome,ASC,IL-18 and iNOS.Compared with the CON group,mice in the LPS group showed obvious decrease in body weight,a significant decrease in EF and FS,a significant increase in LVESD and LVEDD,obvious pathological damage in myocardial tissue,a significant increase in myocardial damage fraction,a significant increase in serum myocardial damage indexes,and a significant increase in the expression levels of BNP,MPO,NLRP3 inflammasome,iNOS,IL-1β,IL-6 and TNF-α.HIIT treatment could reverse these changes mentioned above in model mice.In conclusion,6 weeks of HIIT inhibits the activation of LPS-induced NLRP3 inflammasome and suppressed macrophage M1-type polarization,thereby combating septic myocardial injury.
