Endometriosis is a common chronic gynecological disease with endometrial cell implantation outside the uterus.Angiogenesis is a major pathophysiology in endometriosis.Our previous studies have demon-strated that the prodrug of epigallocatechin gallate(ProEGCG)exhibits superior anti-endometriotic and anti-angiogenic effects compared to epigallocatechin gallate(EGCG).However,their direct binding targets and underlying mechanisms for the differential effects remain unknown.In this study,we demonstrated that oral ProEGCG can be effective in preventing and treating endometriosis.Additionally,1D and 2D Proteome Integral Solubility Alteration assay-based chemical proteomics identified metadherin(MTDH)and PX domain containing serine/threonine kinase-like(PXK)as novel binding targets of EGCG and ProEGCG,respectively.Computational simulation and BioLayer interferometry were used to confirm their binding affinity.Our results showed that MTDH-EGCG inhibited protein kinase B(Akt)-mediated angiogenesis,while PXK-ProEGCG inhibited epidermal growth factor(EGF)-mediated angiogenesis via the EGF/hypoxia-inducible factor(HIF-1a)/vascular endothelial growth factor(VEGF)pathway.In vitro and in vivo knockdown assays and microvascular network imaging further confirmed the involvement of these signaling pathways.Moreover,our study demonstrated that ProEGCG has superior therapeutic effects than EGCG by targeting distinct signal transduction pathways and may act as a novel anti-angiogenic therapy for endometriosis.

Long non-coding RNA (lncRNA) is a type of non-coding RNA with the more than 200 nucleotides. Several lncRNAs have been identified as the potential targets for cancer therapy. LncRNA00067110 is one of the differentially expressed genes in the transcriptome profiles of melanoma B16-F10 cells compared to normal mice melanocytes. To investigate whether lncRNA00067110 regulates the proliferation, apoptosis and melanogenesis of B16-F10 cells, the calcium-binding tyrosine phosphorylation regulated protein (Cabyr) target gene was predicted by LncTar and verified by dual luciferase activities. The regulating function of lncRNA00067110 was investigated by the analysis of transcriptome profiles and to detect the proliferation, apoptosis and melanin production of B16-F10 cells transfected by the overexpression plasmids of lncRNA00067110. The results showed that the relationship of lncRNA00067110 targeting Cabyr, the mRNA and protein levels of proliferation (MEK/ERK/MNK/CREB) and melanogenesis-related genes (TYR family and CREB) were significantly down-regulated, while the mRNA and protein levels of apoptosis-related genes (AKT and Bcl-2) were up-regulated in B16-F10 cells with lncRNA00067110 overexpression. The transcriptome profile of B16-F10 cells with lncRNA00067110 overexpression showed that 17 genes were differentially expressed, among which Cabyr was up-regulated. Furthermore, the effect of lncRNA00067110 on the phenotypes of cell proliferation and apoptosis were verified. The results suggested that lncRNA00067110 might be a novel target for the treatment of melanoma by targeting Cabyr, which regulate the expression of related genes to inhibit the proliferation and melanogenesis, as well as to induce the apoptosis of B16-F10 cells.

OBJECTIVE:
To analyze the characteristics of gene mutation and overexpression in newly diagnosed multiple myeloma (NDMM) patients.
METHODS:
Bone marrow cells from 208 NDMM patients were collected and analyzed. The gene mutation of 28 genes and overexpression of 6 genes was detected by DNA sequencing. Chromosome structure abnormalities were detected by fluorescence in situ hybridization (FISH).
RESULTS:
Gene mutations were detected in 61 (29.33%) NDMM patients. Some mutations occurred in 5 or more cases, such as NRAS, PRDM1, FAM46C, MYC, CCND1, LTB, DIS3, KRAS, and CRBN. Overexpression of six genes (CCND1, CCND3, BCL-2, CCND2, FGFR3, and MYC) were detected in 83 (39.9%) patients, and cell cycle regulation gene was the most common. Single nucleotide polymorphisms (SNP) changes were detected in 169 (81.25%) patients, the TP53 P72R gene SNP (70.17%) was the most common. Abnormality in chromosome structure was correlated to gene overexpression. Compared to the patients with normal chromosome structure, patients with 14q32 deletion showed higher proportion of CCND1 overexpression. Similarly, patients with 13q14 deletion showed higher proportion of FGFR3 overexpression, whereas patients with 1q21 amplification showed higher proportion of CCND2, BCL-2 and FGFR3 overexpression.
CONCLUSION
There are multiple gene mutations and overexpression in NDMM. However, there is no dominated single mutation or overexpression of genes. The most common gene mutations are those in the RAS/MAPK pathway and the genes of cyclin family CCND are overexpression.

OBJECTIVE:
To evaluate the condition of subclinical cardiac damage in children with primary hypertension and the association between serum uric acid and subclinical cardiac damage.
METHODS:
A retrospective analysis was performed on the medical data of 55 children who were hospitalized and diagnosed with primary hypertension in the Department of Cardiology, Children's Hospital of Soochow University from January 2015 to June 2020. Forty-five healthy children, matched for age and sex, were enrolled as the control group. The two groups were compared in terms of clinical features, laboratory examination, and parameters for left ventricular structure, systolic function, and diastolic function. The correlation of serum uric acid with the parameters for left ventricular structure, systolic function, and diastolic function in children with primary hypertension was analyzed.
RESULTS:
Compared with the control group, the hypertension group had significantly higher left ventricular mass (LVM), left ventricular mass index (LVMI), and relative wall thickness (RWT) (
CONCLUSIONS
Children with primary hypertension may have subclinical cardiac damage such as left ventricular hypertrophy, left ventricular diastolic dysfunction, left atrial enlargement, and proximal aortic dilation. Elevated serum uric acid is significantly associated with cardiac damage in children with primary hypertension.

Significantly increasing crop yield is a major and worldwide challenge for food supply and security. It is well-known that rice cultivated at Taoyuan in Yunnan of China can produce the highest yield worldwide. Yet, the gene regulatory mechanism underpinning this ultrahigh yield has been a mystery. Here, we systematically collected the transcriptome data for seven key tissues at different developmental stages using rice cultivated both at Taoyuan as the case group and at another regular rice planting place Jinghong as the control group. We identified the top 24 candi-date high-yield genes with their network modules from these well-designed datasets by developing a novel computational systems biology method, i.e., dynamic cross-tissue (DCT) network analysis. We used one of the candidate genes, OsSPL4, whose function was previously unknown, for gene editing experimental validation of the high yield, and confirmed that OsSPL4 significantly affects panicle branching and increases the rice yield. This study, which included extensive field phenotyping, cross-tissue systems biology analyses, and functional validation, uncovered the key genes and gene regulatory networks underpinning the ultrahigh yield of rice. The DCT method could be applied to other plant or animal systems if different phenotypes under various environments with the common genome sequences of the examined sample.

BACKGROUNDRepetitive transcranial magnetic stimulation (rTMS) and event-related potentials (ERPs) are a noninvasive technique that widely used in neurophysiological field. Although rTMS has shown clinical utility for a number of neurological conditions, Recently,there was little understanding of the the efficacy of rTMS on Schizophrenia(SZ) and the change of ERP between before and after rTMS treatment. The objective of this study was to investigate the characteristics of N400, mismatch negativity (MMN), and P300 before and after treatment with rTMS in SZ.
METHODSOne hundred and twenty-seven SZ patients hospitalized in Shanghai Mental Health Center from March 2015 to July 2017, divided into two groups (85 patients were recruited as rTMS group and 42 were recruited as sham rTMS [ShrTMS] group) and 76 normal controls (NCs) who were the staff and refresher staff in our hospital were recruited at the same time. A Chinese-made rTMS and a Runjie WJ-1 ERPs instrument were used in the present experiment. N400 was elicited by congruent and noncongruent Chinese idioms. After rTMS treatment, N400, P300, and MMN characteristics were compared with those before treatment and NC group.
RESULTSCompared with NC, the SZ patients exhibited delays in N400, P300, and MMN latency and decreased N400, P300, and MMN amplitudes in their frontal area (P < 0.05). After 25 rTMS treatments, N400 amplitudes in the frontal area (elicited by idioms with same phonic and different shape and meaning and with different phonic, shape, and meaning) were increased in the SZ patients (P < 0.05). However, there was no significant change in N400 before and after treatment with ShrTMS in SZ patients (P > 0.05). Amplitudes for MMN and target P300 also increased in SZ patients after rTMS treatment (P < 0.05).
CONCLUSIONSBased on our preliminary findings, we believe that the combined usage of N400, MMN, and P300 could be a valuable index and an electrophysiological reference in evaluating the effects of rTMS treatment in SZ patients.

OBJECTIVETo investigate the relationship between NK cell count/activity and acute graft-versus-host disease (aGVHD) in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT).
METHODSA total of 26 patients who had undergone allo-HSCT from January to July 2015 were enrolled in this study. The NK cell count/activity in the peripheral blood of recipients on day 30 after allo-HSCT were monitored by using 4-color flow cytometry. The incidence of aGVHD in patients was evaluated by clinical manifestation combinating with related pathologic indicators, and the relationship between NK cell count/activity and aGVHD were analyzed.
RESULTSIn the aGVHD group and the no-aGVHD group, the NK cell count and activity on days 30 after allo-HSCT were 655±216 cells/µl vs 1169±372 cells/µl(P=0.002) and 7.3±3.6% vs 9.0±3.6% (P=0.008). In the II-IV grade aGVHD group and the 0-I grade aGVHD group, the NK cell count/activity were 617±220 cells/µl vs 1081±399 cells/µl (P=0.001) and 4.2±1.7% vs 8.3±3.5%(P=0.001). As compared with the 0-I grade aGVHD group, patients in the II-IV grade aGVHD group had higher relapse rate (57% vs 5%)(P=0.010) , lower 1-year progression-free survival(PFS) rate (43% vs 84%)(P=0.010).
CONCLUSIONNK cell count/activity on day 30 after allo-HSCT were closely relates with aGVHD, which may be a potential marker for aGVHD and can provide a new target for aGVHD therapy.
