Cellular heterogeneity within the tumor microenvironment is essential to tumorigenesis and tumor development. Raf activation A high-resolution global view of the tumor-infiltrating immune and stromal cells in breast tumors is needed.

xCell was used to create a cellular heterogeneity map of 64 cell types in 1,092 breast tumor and adjacent normal tissues. xCell digitally dissects tissue cellular heterogeneity based on gene expression. Integrated statistical analyses were then performed.

There were noticeable differences between the cell fractions in tumor tissues and normal tissues. Tumors displayed higher proportions of immune cells, including CD4+ Tem, CD8+ naïve T cells, and CD8+ Tcm compared with normal tissues. Immune inhibitory receptors (PD1, CTLA4, LAG3 and TIM3) were co-expressed on certain subtypes of T cells in breast tumors, and PD1 and CTLA4 were both positively correlated with CD8+ Tcm and CD8+ T cells. 28 cell types were significantly associated with overall survival in univariate analysis. CD4+ Tem, CD8+or the diverse heterogeneity of immune and stromal phenotypes within the breast tumor microenvironment. This map may lead to potential therapeutic targets and biomarkers with prognostic utility.

The purpose of this study was to retrospectively assess the potential correlation between clinical outcomes and homocysteine (Hcy) levels in acute ischemic stroke (AIS) patients after recombinant tissue plasminogen activator (rtPA) treatment.

AIS patients treated by rtPA were enrolled between September 2018 and March 2019 in the Stroke Center (Department of Neurology and Neurosurgery), Shanghai Tenth People's Hospital, Tongji University School of Medicine. Demographics, baseline and clinical characteristics, and modified Rankin Scale (mRS) score after three months from the onset were retrospectively analyzed. Then we compared data about demographics, baseline and clinical characteristics between patients with favorable (mRS score 0-2) and unfavorable (mRS score 3-6) outcomes.

Among 141 patients, 36 patients had poor outcome, for an incidence of 25.53%. Univariate analysis showed that higher Hcy levels (OR = 1.07, 95% CI [1.02-1.12]), older age (OR = 1.06, 95% CI [1.02-1.10]), longer door to needle time plaque) OR = 1.06, 95% CI [1.02-1.11]). The results are very stable in all three models constructed.

The results of this study indicate that increased Hcy level independently predicts unfavorable outcome in AIS patients accepting thrombolytic therapy. However, the contribution of Hcy to the outcome, although significant, is relatively small and perhaps not clinically significant when all the other confounders are considered.

Ischemia-reperfusion (IR) injury is the main cause of delayed graft function in solid organ transplantation. Hypoxia-inducible factors (HIFs) control the expression of genes related to preconditioning against IR injury. During normoxia, HIF-α subunits are marked for degradation by the egg-laying defective nine homolog (EGLN) family of prolyl-4-hydroxylases. The inhibition of EGLN stabilizes HIFs and protects against IR injury. The aim of this study was to determine whether the EGLN inhibitors sodium (

)-2-hydroxyglutarate [(

)-2HG] and succinic acid (SA) have a nephroprotective effect against renal IR injury in Wistar rats.

(

)-2HG was synthesized in a 22.96% yield from commercially available L-glutamic acid in a two-step methodology (diazotization/alkaline hydrolysis), and its structure was confirmed by nuclear magnetic resonance and polarimetry. SA was acquired commercially. (

)-2HG and SA were independently evaluated in male and female Wistar rats respectively after renal IR injury. Rats were dividd to increase IR injury when given at high doses.

The study aimed to explore factors contributing to body weight change over time in gastric cancer patients after gastrectomy, in order to find risk factors to implement nutritional intervention beforehand.

A cohort of gastric cancer patients who were treated with gastrectomy from January to March 2019 at a university affiliated hospital in Shanghai were consecutively identified in this study. Demographics, disease related information, nutrition knowledge, attitude, and practice score were collected before gastrectomy. In addition, body weight before surgery (T0), body weight at one month (T1), two months (T2), and three months (T3) after gastrectomy were recorded. Generalized estimation equation was used to describe body weight change and analyze factors contributing to body weight change after surgery.

There were 49 patients recruited in the study. Patient body weight decreased by 9.2% at T1 (Wald

=271.173,

<0.001), 11.0% at T2 (Wald



=277.267,

<0.001), and 11.4% at T3 compared to baseperative body weight loss for GC patients. The results suggested hinted that clinician should pay attention to postoperative nutrition status of patient undergoing total gastrectomy and obesity patients.MicroRNAs (miRNAs) are important regulators that fine-tune diverse cellular activities. Cynomolgus macaques (Macaca fascicularis) are used extensively in biomedical and pharmaceutical research; however, substantially fewer miRNAs have been identified in this species than in humans. Consequently, we investigated conserved miRNA profiles in cynomolgus macaques by homology searching and small RNA sequencing. In total, 1,455 high-confidence miRNA gene loci were identified, 408 of which were also confirmed by RNA sequencing, including 73 new miRNA loci reported in cynomolgus macaques for the first time. Comparing miRNA expression with age, we found a positive correlation between sequence conservation and expression levels during miRNA evolution. Additionally, we found that the miRNA gene locations in cynomolgus macaque genome were very flexible. Most were embedded in intergenic spaces or introns and clustered together. Several miRNAs were found in certain gene locations, including 64 exon-resident miRNAs, six splice-site-overlapping miRNAs (SO-miRNAs), and two pairs of distinct mirror miRNAs.
