Asymptomatic multicentric Castleman disease: a potential early stage of idiopathic MCD.

According to the diagnostic criteria for human herpesvirus 8 (HHV-8)-negative/idiopathic multicentric Castleman disease (iMCD) proposed by Castleman Disease Collaborative Network in 2017, there is a group of HHV-8-negative patients with multicentric Castleman disease (MCD) who do not have symptoms and hyperinflammatory state and do not meet the iMCD criteria. This retrospective study enrolled 114 such patients, described as asymptomatic MCD (aMCD), from 26 Chinese centers from 2000 to 2021. With a median follow-up time of 46.

Concept for power scaling by harmonic beam coaxial combination in an intra-cavity frequency doubling laser.

A new method of harmonic beam coaxial combination (HBCC) from two intra-cavity frequency doubling branches was demonstrated. Firstly, two identical nanosecond (ns) 532 nm green lasers with high power and good beam quality were created. Each green laser was constructed of an intra-cavity frequency doubling branch based on a laser diode (LD) end-pumped acousto-optical (AO) Q-switched 1064 nm Nd:YVO laser in a LiBO (LBO) nonlinear crystal.

Predicting leukemic transformation in myelodysplastic syndrome using a transcriptomic signature.

For prediction on leukemic transformation of MDS patients, emerging model based on transcriptomic datasets, exhibited superior predictive power to traditional prognostic systems. While these models were lack of external validation by independent cohorts, and the cell origin (CD34 sorted cells) limited their feasibility in clinical practice. Transformation associated co-expressed gene cluster was derived based on GSE58831 ('WGCNA' package, R software).

A national, multicenter, retrospective study of Castleman disease in China implementing CDCN criteria.

Background: Castleman disease (CD) is a group of rare and heterogenous lymphoproliferative disorders including unicentric CD (UCD), human herpesvirus-8(HHV-8)-associated multicentric CD (HHV8-MCD), and HHV-8-negative/idiopathic multicentric CD (iMCD). Knowledge of CD mainly comes from case series or retrospective studies, but the inclusion criteria of these studies vary because the Castleman Disease Collaborative Network (CDCN) diagnostic criteria for iMCD and UCD were not available until 2017 and 2020, respectively. Further, these criteria and guidelines have not been systematically evaluated.

Overexpression of WT1 and PRAME predicts poor outcomes of patients with myelodysplastic syndromes with thrombocytopenia.

Thrombocytopenia is associated with life-threatening bleeding and is common in myelodysplastic syndromes (MDS). Robust molecular prognostic biomarkers need to be developed to improve clinical decision making for patients with MDS with thrombocytopenia. Wilms tumor 1 (WT1) and preferentially expressed antigen in melanoma (PRAME) are promising immunogenic antigen candidates for immunotherapy, and their clinical effects on patients with MDS with thrombocytopenia are still not well understood.

The potential role of HO-1 in regulating the MLK3-MKK7-JNK3 module scaffolded by JIP1 during cerebral ischemia/reperfusion in rats.

Heme oxygenase (HO-1), which may be induced by Cobaltic protoporphyrin IX chloride (CoPPIX) or Rosiglitazone (Ros), is a neuroprotective agent that effectively reduces ischemic stroke. Previous studies have shown that the neuroprotective mechanisms of HO-1 are related to JNK signaling. The expression of HO-1 protects cells from death through the JNK signaling pathway.

[Correlations Between Substrate Structure and Microbial Community in Subsurface Flow Constructed Wetlands].

To identify the microbial factors that cause the differences in the purification performance of constructed wetlands with different substrate structures, the relationship between the substrate structure and the microbial community composition in horizontal subsurface flow constructed wetlands (HSSFCWs) was studied by high throughput sequencing. The results revealed that the purification performance of a six-layer constructed wetland (CW6), of which the permeability coefficient gradually increased from the surface layer to the bottom layer, was the highest among the three constructed wetland systems. The average concentrations of COD, TN, NO-N, and NH-N in the effluent were 39, 11, 0.

Background: We examined whether detecting the heavy chain of cytoplasmic immunoglobulin D (IgD) by flow cytometry could be used as a supplemental method to diagnose IgD multiple myeloma (MM).

Methods: Bone marrow (BM) samples of thirty-five patients with MM were collected. Five of them were IgD MM, the rest of thirty were other subtypes of MM.

UPLC-QTOF-MS/MS-guided isolation and purification of sulfur-containing derivatives from sulfur-fumigated edible herbs, a case study on ginseng.

In this study, a novel ultra-performance liquid chromatography coupled with quadrupole/time-of-flight mass spectrometry (UPLC-QTOF-MS/MS)-guidance strategy was proposed for preparation of sulfur-containing derivatives in sulfur-fumigated edible herbs.

Non-malignant T-cells lacking multiple pan-T markers can be found in lymph nodes.

In order to observe and ascertain the properties of a sub-group of T cells in the lymph node (LN) from seven patients who did not suffer from T cell lymphoproliferative disorders (T-LPDs), the expression levels of several pan-T markers were evaluated by multiparameter flow cytometry (FC) and the clonality of these T-cells was evaluated by both FC analysis and PCR assessment. It turned out that multiple pan-T-cell markers such as CD2, CD5 and CD7 were found to be lost in these T cells. The majority of them were positive for TCRαβ, only a minority of them being positive for TCRγδ.
