Notes

Arabidopsis thaliana Zn 2+-efflux ATPases HMA2 and HMA4 are essential regarding resistance to the necrotrophic infection Plectosphaerella cucumerina BMM.
To evaluate the clinical characteristics, genetic abnormalities, treatment efficacy and prognostic factors in patients with plasma cell leukemia(PCL).

30 patients diagnosed as PCL in our hospital from January 1993 to December 2019 were enrolled, and the clinical characteristics, laboratory findings, therapeutic regimes, and survival data of the patients were retrospectively analyzed.

The median age of the 30 patients was 56.5 (28-80) years old, among them, 25 patients were primary plasma cell leukemia, and 5 patients were secondary plasma cell leukemia. Complex karyotypes and subdiploids were most common in cytogenetic abnormalities. Among the 20 cases of chromosome G banding, 11 (55%) cases were complex karyotypes and 8 (40%) cases were hypodiploid. Fluorescent in situ hybridization (FISH) test showed that among 11 cases, 6 cases showed 17p13 deletion, 8 cases showed at least two kinds of abnormalities, which including t (14; 16), t (8; 14), t (11;14), 17p13 deletion, and 13q14 deletion. The median ove the pulmonary infection within 6 months after transplantation.

In the era of novel agents, ECOG score is an independent prognostic factor of plasma cell leukemia. Multiple novel agents treatment should be underwent as soon as possible to improve the prognosis of the patients. Pulmonary infection is a common factor that cause the death of the patients after allogeneic hematopoietic stem cell transplantation.

To investigate the mechanisms of anti-apoptosis and immune evasion in drug-resistant leukemia cells mediated by STAT3, further to explore the possible mechanism of leukemia relapse caused by minimal residual.

Drug-resistance leukemia cell line was established by transfecting pcDNA3.1-STAT3 into K562 cells (K562/STAT3). The expression of STAT3, BAX and NKG2D ligands (MICA and ULBP1) in K562/-cells, K562/STAT3 were detected by Western blot and/or RQ-PCR. Cells apoptosis and the killing effect of NK cells on leukemia cells were detected by flow cytometry.

The expression of the total STAT3, STAT3 phosphorylation in K562/STAT3 was significantly increased, and P-gp mRNA expression was increased also significantly (P<0.005). In K562/STAT3 cells, the expression of pro-apoptotic BAX (P=0.005) was significantly lower, and the number of apoptotic cells (P=0.002) induced by adriamycin was significantly decreased as compared with those in K562/- cells. After K562/STAT3 cells were treated by STAT3 inhibitor (SH-4-n inhibits cell apoptosis and promotes cell immune escape. STAT3 inhibitors can promote the apoptosis of leukemia cells and increase their sensitivity to NK cells.
To analyze the characteristics of gene mutation in adult ALL and its clinical significance.

Clinical data of 134 primary adult ALL patients and DNA sequencing results of 16 kinds of gene mutation were collected. The characteristic of gene mutation and clinical significances were statistically analyzed.

In 31 cases of 134 ALL cases (23.13%) the gene mutations were detected as follows 19 cases of 114 B-ALL cases (16.67%), 11 cases of 19 T-ALL cases (57.89%) and 1 case of T/B-ALL. BMS-387032 mouse The incidence of T-ALL gene mutation was significantly higher than that of B-ALL (χ
=13.574, P<0.01). Twelve gene mutations were found, and the mutation rates was IL7R, NOTCH1, FLT3, TP53, FBXW7, PAX5, IKZF1, CREBBP, JAK3, JAK1, PHF6 and PTEN from high to low. Among 108 non-transplantable follow-up patients there was no significant difference in 1-year overall survival rate (49.7% vs 67.4%) and median non-recurrence survival time (214 days vs 260 days) between the gene mutation group (23 cases, 21.30%) and the non-mutation group(85 cases, 78.70%). There was a significant difference in 1-year survival rate between NOTCH1 mutation group (4 cases, 3.77%) and non-mutation group (102 cases, 96.23%) (50.0% vs 65.8%,χ
=9.840, P<0.01).

There may be multiple gene mutations in adult ALL patients. IL7R and NOTCH1 are the most common gene mutations and NOTCH1 mutation may indicate poor prognosis. Detection of gene mutations is helpful to understand the pathogenesis of ALL and evaluate the prognosis of adult ALL patients.

The coronavirus disease 2019 (COVID-19) outbreak has become a pandemic. Obstetricians and midwives, among other medical staff, are tackling COVID-19 and are under immense psychological stress.

We aimed to survey the mental health of non-infectious disease specialist staff, specifically obstetricians and midwives, working in officially designated hospitals treating patients with COVID-19.

A nationwide online survey was conducted from 7 March to 17 March 2020 investigating the mental health of obstetricians and midwives (who were not themselves infected with COVID-19) working in hospitals treating patients with COVID-19. We used the 9-item Patient Health Questionnaire (PHQ-9), the 7-item Generalized Anxiety Disorder (GAD-7) scale and the 7-item Insomnia Severity Index (ISI) to assess their symptoms of depression, anxiety and insomnia.

A total of 885 (41.6%), 609 (28.6%) and 729 (34.3%) obstetricians and midwives reported depression (PHQ-9 ≥ 5), anxiety (GAD-7 ≥ 5) and insomnia (ISI ≥ 8), respectively, dould be reduced by sufficient levels of protective equipment and occupational COVID-19 workplace training.
Although age and pre-existent dementia are robust risk factors for developing delirium, evidence for patients older than 90 years is lacking. Therefore, this study assesses the delirium prevalence rates and sequelae in this age group.

Based on a Diagnostic and Statistical Manual (DSM)-5, Delirium Observation screening scale (DOS), and Intensive Care Delirium Screening Checklist (ICDSC) construct, in this prospective cohort study, the prevalence rates and sequelae of delirium were determined in 428 patients older than 90 years by simple logistic regressions and corresponding odds ratios (ORs).

The overall prevalence delirium rate was 45.2%, with a wide range depending upon specialty intermediate and intensive care services (83.1%), plastic surgery and palliative care (75%), neurology (72%), internal medicine (69%) vs. dermatology (26.5%), and angiology (14.5%). Delirium occurred irrespective of age and gender; however, pre-existent dementia was the strongest delirium predictor (OR 36.05). Delirious patients were less commonly admitted from home (OR 0.
