OBJECTIVETo study the effects of Angelica sinensis Polysaccharides (ASP) on the hepatic drug metabolism enzymes activities in normal mice and those prednisolone (PSL)-induced liver injury.

METHODThe activities of phase II enzymes (GSH-related enzymes) and cytochrome P450 enzymes were measured by biochemical method.

RESULTASP increased the activities of glutathione S-transferase in liver microsomes and mitochondria. The cytochrome P450 content, NADPH-cytochrome c reductase, aminopyrine N-demethylase, and aniline hydroxylase activities in liver microsomes were also increased. PSL significantly increased serum ALT levels, and decreased the liver mitochondrial glutathione content. At the same time, other enzymes activities were all increased. When mice were treated with ASP 2.0 g.kg-1, the PSL-induced changes on cytochrome P450 enzymes, glutathione S-transferase, and GSH content were restored.

CONCLUSIONASP can modulate the activities of drug metabolism enzymes.

Purpose: This study aimed to analyze the expression and prognosis of SRY-box transcription factor 11 (SOX11) in neuroblastoma (NB), as well as the biological function and potential regulatory mechanism of SOX11 in NB. Methods: Public RNA sequencing was used to detect the expression level of SOX11. The Kaplan-Meier curve and hazard ratios (HR) were used to determine the prognostic value of SOX11 in NB. Functional analyses were performed using CCK8, wound healing assay, and transwell invasion assay. Finally, the potential target genes of SOX11 were predicted by Harmonizonme (Ma'ayan Laboratory) and Cistrome Data Browser (Cistrome Project) database to explore the potential molecular mechanism of SOX11 in NB. Results: Compared with normal adrenal tissue, the expression of SOX11 in NB tissue was significantly upregulated. The Kaplan-Meier curve showed that high expression of SOX11 was associated with poor prognosis in children with NB (HR, 1.719; P = 0.049). SOX11 knockdown suppressed the migration capacity of SK-N-SH cells but did not affect proliferation and invasion capacity. Enhancer of zeste homolog 2 (EZH2) may be a potential downstream target gene for the transcription factor SOX11 to play a role in NB. Conclusion The transcription factor SOX11 was significantly upregulated in NB. SOX11 knockdown suppressed the migration capacity of NB cell SK-N-SH. SOX11 may promote the progression of NB by targeting EZH2.

Objective·To screen NPHS2 mutations in adult focal segmental glomerulosclerosis(FSGS)patients based on a large Chinese FSGS cohort. Methods · All patients were biopsy determined FSGS by the Department of Nephrology at Ruijin Hospital affiliated to Shanghai Jiao Tong University School of Medicine. FSGS secondary to systemic disease and other hereditary kidney disease were excluded. After extraction of genomic DNA of peripheral blood,NPHS2 was screened by directly sequencing the exon/intron junction or high-throughput sequencing,including whole exon sequencing and Panel sequencing, and then verified by Sanger sequencing. One hundred healthy controls were enrolled to validate candidate mutations. Results · Two hundred and four FSGS patients were enrolled,including 52 familial(25.5%) and 152 sporadic patients(74.5%),of which steroid-resistant FSGS patients accounted for 30.3%(46/152).By sequencing NPHS2 in all patients of the cohort(Sanger sequencing in 61 patients and high-throughput sequencing in 143 patients), 2 novel conserved mutations were identified, one homozygous mutation in sporadic steroid-resistant FSGS, p.N199I and one heterozygous mutation in familial FSGS, p.L321fx346. Both of them were not detected in 100 healthy controls. These two variants were predicted to be damaging by Polyphen,SIFT and Mutation Taster.Totally,the mutation rate of NPHS2 in the FSGS cohort was 1%. Conclusion·Since the overall frequency of NPHS2 mutations is considerably low in Chinese adult-onset FSGS,NPHS2 is not the main disease-causing gene of this group of people.

Cardiac stem cells (CSCs) transplantation has been recognized to be effective on the treatment of myocardial infarction (MI), but some techniques still need to be developed in the isolation and culture of CSCs, which is the key problem restricting the clinical application of CSCs. This study was focused on the isolation of Lin(lineage-negative) Sca-1(stem cell antigen-1-positive) CSCs from newborn C57BL/6J mice (0-3 d) by mixed enzymatic-explant isolation in combination with immunomagnetic separation. The digesting time, digesting frequency, incubation temperature, stirring speed, centrifugation time and rotational speed were strictly controlled in the experiment. In order to increase the survival rate of CSCs, the medium changing time and manner were optimized in primary CSCs culture. The percentages of Sca-1cells in primary and passage cells were detected by flow cytometry and immunofluorescence staining. The results showed that: (1) the proportion of LinSca-1cells within the collected cells could be as high as (85.03 ± 5.60)% after isolation and purification; (2) In vitro culture of LinSca-1CSCs grew into spheres on the 5day, and over the whole bottom of the dish on the 7day. The growth curve showed that the cells were in logarithmic growth phase on the 3day; (3) Immunofluorescence staining data showed that the expression of Sca-1, the CSCs membrane-specific marker, was decreased after subculture, and flow cytometry data showed that the percentages of Sca-1cells were (71.82 ± 2.63)%, (58.38 ± 3.70)% and (46.19 ± 4.72)% in passage 1 (P1), P3, and P5 CSCs, respectively. The above results suggest that high purity of LinSca-1CSCs can be obtained by enzymolysis combined with immunomagnetic separation method. Moreover, the CSCs culture system is stable. In our experiment, the Sca-1CSCs isolation and culture method has been successfully established, and it is simple, stable, effective and reliable. The method can provide a stable methodological basis for the treatment of MI by LinSca-1CSCs transplantation.

OBJECTIVE: To investigate humanistic practice ability of nurses in a general hospital in Hunan Province and analyze the factors affecting their practices to provide evidence for interventions to improve humanistic practice ability of the nurses. METHODS: A total of 1196 nurses were surveyed using a self-designed questionnaire and a nurse humanistic practice ability assessment scale questionnaire for assessment of their abilities for humanistic care practice, psychological adjustment, interpersonal communication, self-management, ethics and legal practice. Univariate and multivariate analyses were performed for analysis of the factors affecting the practice abilities of the nurses. RESULTS: The total score of humanistic practice ability of the 1196 nurses was 105.69±16.45 (the full score of the scale was 130), and the scores of humanistic care practice ability, psychological adjustment ability, interpersonal communication ability, self-management ability, ethics and legal practice ability were 40.95±6.46, 16.41±2.66, 16.41±2.66, 11.32±2.05 and 12.43±2.00, respectively. Univariate analysis and multiple linear regression analysis showed that gender (P=0.033), age (P < 0.001), department (P=0.015), working years (P < 0.001), professional title (P < 0.001), first academic degree (P < 0.001), highest academic degree (P < 0.001), family location (P=0.010), marital status (P=0.023), number of patients to care for (P=0.022), number of children (P=0.001), previous humanities related training (P < 0.001), training times (P < 0.001), and care received from family members (P < 0.001) and colleagues (P < 0.001) were all the factors affecting humanistic practice ability of the nurses. Among these factors, age, working in department of obstetrics and gynecology and emergency department, professional title, humanities training, and care from family and colleagues explained 20.7% of the variance. CONCLUSION The humanistic practice ability of nurses in this general hospital is above the average level, but their self-management ability needs to be improved. Intervention measures should be implemented to improve the nurses' humanistic practice ability including more attentions to the key groups and departments, strengthening the training of humanistic practice ability, and improving the promotion assessment system.
