Mechanism of Qiwei Guibao Granules in treatment of premature ovarian failure based on proteomics / 中国中药杂志

In this study, the underlying mechanism of Qiwei Guibao Granules(QWGB) in the treatment of premature ovarian fai-lure(POF) was explored by the proteomics technique. Firstly, the POF model was induced in mice by intragastric administration of Tripterygium wilfordii glycosides solution at 50 mg·kg~(-1) for 14 days. Ten days prior to the end of the modeling, the estrous cycle of mice was observed every day to evaluate the success of modeling. From the 1st day after modeling, the POF model mice were treated with QWGB by gavage every day and the treatment lasted four weeks. On the 2nd day after the end of the experiment, blood was collected from the eyeballs and the serum was separated by centrifugation. The ovaries and uterus were collected and the adipose tissues were carefully stripped. The organ indexes of the ovaries and uterus of each group were calculated. The serum estrogen(E_2) level of mice in each group was detected by ELISA. Protein samples were extracted from ovarian tissues of mice, and the differential proteins before and after QWGB intervention and before and after modeling were analyzed by quantitative proteomics using tandem mass tags(TMT). As revealed by the analysis of differential proteins, QWGB could regulate 26 differentially expressed proteins related to the POF model induced by T. wilfordii glycosides, including S100A4, STAR, adrenodoxin oxidoreductase, XAF1, and PBXIP1. GO enrichment results showed that the 26 differential proteins were mainly enriched in biological processes and cellular components. The results of KEGG enrichment showed that those differential proteins were involved in signaling pathways such as completion and coalescence cascades, focal adhesion, arginine biosynthesis, and terpenoid backbone biosynthesis. The complement and coalescence cascades signaling pathway was presumably the target pathway of QWGB in the treatment of POF. In this study, the proteomics technique was used to screen the differential proteins of QWGB in the treatment of POF in mice induced by T. wilfordii glycosides, and they were mainly involved in immune regulation, apoptosis regulation, complement and coagulation cascade reactions, cholesterol metabolism, and steroid hormone production, which may be the main mechanisms of QWGB in the treatment of POF.

Characteristics, origin, and processing of Poria in Qing Dynasty Palace:evidence of both historical relics and documents / 中国中药杂志

Poria(Fu Ling) is a bulk traditional Chinese medicine(TCM)with a long history and complex varieties. The royal medical records of the Qing Dynasty include multiple medicinal materials of Fu Ling, such as Bai Fu Ling(white Poria), Chi Fu Ling(rubra Poria), and Zhu Fu Ling(Poria processed with cinnabaris). The Palace Museum preserves 6 kinds of specimens including Fu Ling Ge(dried Poria), Bai Fu Ling, Chi Fu Ling, Zhu Fu Ling, Bai Fu Shen(white Poria cum Radix Pini), and Fu Shen Mu(Poria cum Radix Pini). After trait identification and textual research, we found that Fu Ling Ge was an intact sclerotium, which was processed into Fu Ling Pi(Poriae Cutis), Bai Fu Ling and other medicinal materials in the Palace. The Fu Ling in the Qing Dynasty Pa-lace was mainly from the tribute paid of the officials in Yunnan-Guizhou region. The tribute situation was stable in the whole Qing Dynasty, and changed in the late Qing Dynasty. The cultural relics of Fu Ling in the Qing Dynasty Palace confirm with the archival documents such as the royal medical records and herbal medicine books, providing precious historical materials for understanding Fu Ling in the Qing Dynasty and a basis for the restoration of the processing of the Fu Ling in the Qing Dynasty Palace.

The Role and Regulatory Mechanism of ZSCAN4 in Early Embryonic and Pluripotent Stem Cells / 中国生物化学与分子生物学报

Zinc finger and SCAN domain containing 4 (ZSCAN4) is specifically expressed as a DNA-binding protein in 2-cell stage embryos and embryonic stem cells. ZSCAN4 regulates early embryonic development by promoting DNA damage repair and correcting chromosomal abnormalities during zygotic genome activation (ZGA) to maintain genomic and chromosomal integrity in preimplantation embryos. During the transition of mouse embryonic stem cells (mESCs) to 2-cell-like cells, ZSCAN4 interacts with ATP-dependent chromatin remodelers to regulate the activity of murine endogenous retroviral L enhancers, and activate the expression of peripheral 2-cell-phase genes to promote the transition of embryonic stem cells to 2-cell-like cells. ZSCAN4 can also promote telomere reorganization and telomere extension by reducing DNA methylation levels to mediate heterochromatin silencing, maintain genome stability and the infinite self-renewal capacity and pluripotency of pluripotent stem cells, and promote mESCs transition to embryonic 2-cell-like cells. In addition, ZSCAN4 can also reactivate early embryonic genes in reprogramming, and significantly increase the generation efficiency of induced pluripotent stem cells (iPSCs). ZSCAN4 reduces DNA damage during iPSCs formation, and preserves genome stability by lengthening telomeres, thereby promoting the generation of high-quality iPSCs without genetic defects. This article focuses on the research advances of the biological functions of ZSCAN4 in regulating early embryonic development, mediating telomere elongation in pluripotent stem cells, and its role in somatic cell reprogramming, which may provide a reference for optimizing the technology to increase the early embryonic development and maintenance of pluripotent stem cells and iPSC generation.

Plurihormonal PIT1-lineage pituitary neuroendocrine tumors: a clinicopathological study / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics of plurihormonal PIT1-lineage pituitary neuroendocrine tumors. Methods: Forty-eight plurihormonal PIT1-lineage tumors were collected between January 2018 and April 2022 from the pathological database of Sanbo Brain Hospital, Capital Medical University. The related clinical and imaging data were retrieved. H&E, immunohistochemical and special stains were performed. Results: Out of the 48 plurihormonal PIT1-lineage tumors included, 13 cases were mature PIT1-lineage tumors and 35 cases were immature PIT1-lineage tumors. There were some obvious clinicopathological differences between the two groups. Clinically, the mature plurihormonal PIT1-lineage tumor mostly had endocrine symptoms due to increased hormone production, while a small number of immature PIT1-lineage tumors had endocrine symptoms accompanied by low-level increased serum pituitary hormone; patients with the immature PIT1-lineage tumors were younger than the mature PIT1-lineage tumors; the immature PIT1-lineage tumors were larger in size and more likely invasive in imaging. Histopathologically, the mature PIT1-lineage tumors were composed of large eosinophilic cells with high proportion of growth hormone expression, while the immature PIT1-lineage tumors consisted of chromophobe cells with a relatively higher expression of prolactin; the mature PIT1-lineage tumors had consistently diffuse cytoplasmic positive staining for keratin, while the immature PIT1-lineage tumors had various expression for keratin; the immature PIT1-lineage tumors showed more mitotic figures and higher Ki-67 proliferation index; in addition, 25.0% (12/48) of PIT1-positive plurihormonal tumors showed abnormal positive staining for gonadotropin hormones. There was no significant difference in the progression-free survival between the two groups (P=0.648) by Kaplan-Meier analysis. Conclusions: Plurihormonal PIT1-lineage tumor belongs to a rare type of PIT1-lineage pituitary neuroendocrine tumors, most of which are of immature lineage. Clinically increased symptoms owing to pituitary hormone secretion, histopathologically increased number of eosinophilic tumor cells with high proportion of growth hormone expression, diffusely cytoplasmic keratin staining and low proliferative activity can help differentiate the mature plurihormonal PIT1-lineage tumors from the immature PIT1-lineage tumors. The immature PIT1-lineage tumors have more complicated clinicopathological characteristics.

Mutational spectrum and its prognostic significance in childhood acute lymphoblastic leukemia based on next-generation sequencing technology / 中华血液学杂志

Objective: This study analyzed the correlation between genetic mutation and prognostic significance in childhood acute lymphoblastic leukemia (ALL) . Methods: Targeted exome by next-generation sequencing (NGS) technology was used to carry out molecular profiling of untreated 141 children with ALL in Fujian Medical University Union Hospital from November 2016 to December 2019. Correlation of genetic features and clinical features and outcomes was analyzed. Results: Among the 141 pediatric patients with ALL, 160 somatic mutations were detected in 83 patients (58.9% ) , including 37 grade Ⅰ mutations and 123 grade Ⅱ mutations. Single nucleotide variation was the most common type of mutation. KRAS was the most common mutant gene (12.5% ) , followed by NOTCH1 (11.9% ) , and NRAS (10.6% ) . RAS pathway (KRAS, FLT3, PTPN11) , PAX5 and TP53 mutations were only detected, and NRAS mutations was mainly found in B-ALL while FBXW7 and PTEN mutations were only found, and NOTCH1 mutation was mainly detected in T-ALL. The average number of mutations detected in each child with T-ALL was significantly higher than in children with B-ALL (4.16±1.33 vs 2.04±0.92, P=0.004) . The children were divided into mutation and non-mutation groups according to the presence or absence of genetic variation. There were no statistically significant differences in sex, age, newly diagnosed white blood cell count, minimal or measurable residual disease monitoring results, expected 3-year event-free survival (EFS) and overall survival (OS) between the two groups (P>0.05) . On the other hand, the proportion of T-ALL and fusion gene negative children in the mutant group was significantly higher than the non-mutation group (P=0.021 and 0.000, respectively) . Among the patients without fusion gene, the EFS of children with grade I mutation was significantly lower than children without grade I mutation (85.5% vs 100.0% , P=0.039) . Among children with B-ALL, the EFS of those with TP53 mutation was significantly lower than those without TP53 mutation (37.5% vs 91.2% , P<0.001) . Conclusion: Genetic variation is more common in childhood ALL and has a certain correlation with clinical phenotype and prognosis. Therefore, targeted exome by NGS can be used as an important supplement to the traditional morphology, immunology, cytogenetics, and molecular biology classification.

Protective effect of excretory-secretory proteins from Trichinella spiralis muscle larvae against myocardial injury in septic mice / 南方医科大学学报

OBJECTIVE@#To evaluate the protective effect of excretory-secretory proteins from Trichinella spiralis muscle larvae (Ts-MES) on sepsis-induced myocardial injury in mice.@*METHODS@#Eighty male BALB/C mice were randomized equally into sham-operated group, myocardial injury group, Ts-MES treatment group and dexamethasone treatment group. In the latter 3 groups, sepsis-induced myocardial injury models were established by cecal ligation and perforation; the sham operation was performed by exposure of the cecum without ligation or perforation. Forty minutes after the operation, the mice were given intraperitoneal injections 150 μL PBS, 20 μg TS-MES or 0.3 mg/kg dexamethasone as indicated. At 12 h after the operation, 6 mice were randomly selected from each group for echocardiography, and 8 mice were used for observing the survival rate within 72 h. The remaining 6 mice were examined for myocardial pathologies with HE staining and serum levels of NTPro-BNP and cTnI with ELISA; the expressions of TNF-α, IL-6, IL-10 and TGF-β in the serum and myocardial tissue were detected using ELISA and qRT-PCR.@*RESULTS@#Compared with the sham-operated mice, the septic mice showed significantly decreased cardiac function indexes (LVEF, LVFS, and E/A) with lowered survival rate within 72 h (P < 0.001) and significantly higher myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.01). Treatment with TS-MES significantly improved the cardiac function and 72-h survival rate (P < 0.05) and lowered the myocardial injury scores and serum levels of NTPro-BNP and cTnI (P < 0.05) in the septic mice. Compared with the sham-operated mice, the septic mice had obviously increased TNF-α and IL-6 levels in the serum and myocardial tissue (P < 0.001), which were significantly lowered by treatment with TS-MES (P < 0.05). TS-MES and dexamethasone both increased the levels of IL-10 and TGF-β in the septic mice, but the changes were significant only in TS-MES-treated mice (P < 0.05).@*CONCLUSION@#Ts-MES are capable of protecting against myocardial injury in septic mice by reducing the production of pro-inflammatory cytokines and enhancing the levels of regulatory cytokines.

Pediatric SMARCB1/INI1-deficient poorly differentiated chordoma of the skull base: report of five cases and review of literature / 中华病理学杂志

Objective: To investigate the clinicopathological characteristics and differential diagnosis of pediatric SMARCB1/INI1-deficient poorly differentiated chordoma (PDC) of the skull base. Methods: Five cases of SMARCB1/INI1-deficient PDC were identified in 139 cases of chordoma diagnosed in Sanbo Brain Institute, Capital Medical University, Beijing, China from March 2017 to March 2021. The clinical and imaging data of the 5 PDCs were collected. H&E and immunohistochemical staining, and DNA methylation array were used, and the relevant literatures were reviewed. Results: All 5 PDCs were located at the clivus. The average age of the patients was 6.4 years, ranging from 3 to 16 years. Three patients were female and two were male. Morphologically, in contrast with classical chordomas, they presented as epithelioid or spindle tumor cells organized in sheets or nests, with necrosis, active mitoses, and infiltration into surrounding tissue. All cases showed positivity of CKpan, EMA, vimentin and brachyury (nuclear stain), and loss of nuclear SMARCB1/INI1 expression. S-100 protein expression was not frequent (2/5). Ki-67 proliferative index was high (20%-50%). All cases had over-expressed p53. It was necessary to differentiate SMARCB1/INI1-dificient PDC from SMARCB1/INI1-dificient tumors occurring at skull base of children or the tumors with epithelial and spindle cell morphological features. The 3 PDCs with DNA methylation testing showed the methylation profiles different from the pediatric atypical teratoid/rhabdoid tumors. They formed an independent methylation profile cluster. The clinical prognosis of the 5 patients was poor, and the overall survival time was 2-17 months. Conclusions: PDC is a special subtype of chordoma, which often affects children and occurs in the clivus. The PDC shares epithelioid or spindle cell morphologic features which are different from the classic chordoma. Besides the typical immunohistochemical profile of chordoma, PDC also has loss of nuclear SMARCB1/INI1 expression and distinct epigenetic characteristics.

The application of Compont gel in chronic obstructive jaundice rats model

Abstract Purpose: To establish a new rat model, the pathogenesis of which is closer to the clinical occurrence of chronic obstructive jaundice with liver fibrosis. Methods: 90 SD rats were randomly divided into 3 groups. Group A common bile duct ligation, group B common bile duct injection compont and group C injection saline. The serum of three groups was extracted, and the liver function was detected by ELISA. HE staining, Masson staining and immunohistochemistry were used to detect liver pathology. Results: Group B showed a fluctuant development of jaundice, obstructive degree reached a peak at 2 weeks, and decreased from 3 weeks. HA, LA and PCIII were significantly higher than control group. 3 weeks after surgery, liver tissue fibrosis occurred in group B, and a wide range of fiber spacing was formed at 5 weeks. Immunohistochemistry showed that hepatic stellate cells were more active than the control group. Conclusion: Intra-biliary injection of Compont gel is different from the classic obstructive jaundice animal model caused by classic bile duct ligation, which can provide an ideal rat model of chronic obstructive jaundice with liver fibrosis.

Artesunate promotes Th1 differentiation from CD4+ T cells to enhance cell apoptosis in ovarian cancer via miR-142

The aim of this study was to evaluate the influence of artesunate on Th1 differentiation and its anti-tumor effect on ovarian cancer. A Murine ovarian cancer model was established by ID8 cells transplantation. The expression of miR-142 and Sirt1 proteins in peripheral CD4+ T cells were quantified with qRT-PCR and western blot, respectively. Peripheral CD4+ T cells were induced for Th1 differentiation. The percentages of apoptosis of Th1/CD4+ T cells and ovarian cancer cells were analyzed by flow cytometry. The IFN-γ level was examined through enzyme-linked immunosorbent assay. Artesunate promoted miR-142 expression in peripheral CD4+ T cells and Th1 differentiation from CD4+ T cells. Artesunate promoted cell apoptosis of ovarian cancer cells by inducing Th1 differentiation. By up-regulating miR-142, artesunate suppressed Sirt1 level and promoted Th1 differentiation. Artesunate enhanced the pro-apoptotic effects of Th1 cells on ovarian cancer via the miR-142/Sirt1 pathway. Artesunate promoted Th1 differentiation from CD4+ T cells by down-regulating Sirt1 through miR-142, thereby enhancing cell apoptosis in ovarian cancer.
