Effects of Humulus lupulus L. and its active ingredient xanthohumol on preventing glucocorticoid-induced osteoporosis / 药学实践杂志

Objective To explore the effects of Humulus lupulus L. extract (HLE) and xanthohumol (XN) on preventing glucocorticoid-induced osteoporosis (GIOP). Methods The GIOP model was established by intraperitoneal injection of dexamethasone (DEX). Bone microstructure, bone mineral density and serum biochemical indexes were evaluated by Micro-CT and ELISA kits. The levels of cells proliferation and ALP activity, and the expression of bone formation related proteins were assayed with primary osteoblasts injured by DEX. Results HLE and XN significantly alleviated the bone microstructure damage, enhanced the bone mineral density, and improved the trabecular parameters in GIOP mice. In vitro experiments showed that HLE and XN can prevent bone loss not only by improving cell proliferation and ALP activity, but also through increasing the expression of bone γ-glutamic acid-containing proteins (BGP), bone morphogenetic protein 2 (BMP-2) and runt-related transcription factor 2 (Runx-2). Conclusion This study confirmed that HLE and XN had anti-GIOP effects for the first time. It provides a new resource for the development of anti-osteoporosis medications.

Expression of PKCι/YAP1 in Cervical Cancer and Its Clinical Significance / 肿瘤防治研究

Objective To investigate the role of PKCι, YAP1 and high-risk HPV infection in the local immune microenvironment of cervical cancer. Methods We chose 80 cases of normal tissue of the cervix (NCT), cervical low-grade squamous intraepithelial lesion (LSIL), cervical high-grade squamous intraepithelial lesion (HSIL) and early cervical squamous cell carcinoma (SCC) each. Four groups were collected.The infection rate of high-risk HPV in four groups was determined by real-time fluorescence PCR method. The expression levels of PKCι, YAP1, CD4 and CD8 in four groups were measured and correlated by IHC and clinicopathologic features were also analyzed. Results The differences of high-risk HPV infection rate and PKCι, YAP1, CD4, CD8 positive rate among groups of NCT, LSIL, HSIL and SCC had statistical significance (P < 0.05). The level of cervical lesions was positively associated with high-risk HPV infection and positive PKCι, YAP1, CD8 expression (P < 0.05), while negatively associated with positive CD4 expression (P < 0.05). HPV infection and positive PKCι, YAP1, CD8 expression were positively correlated with each other in SCC, while were all negatively correlated with positive CD4 expression(P < 0.05). The differences of HPV infection, PKCι, YAP1 and CD8 positive expression were significant in different levels of differentiation and vascular invasion of SCC (P < 0.05). Conclusion The patients with cervical lesions are often accompanied by high-risk HPV infection and abnormal expression of PKCι, YAP1, CD4 and CD8, which may have synergistic effects on each other, causing the local immunosuppression microenvironment of SCC. It provides a possible strategy for the study of pathogenesis, diagnosis and treatment of cervical cancer.

Hops extract alleviates Aβ-injury to osteoblasts through antioxidant pathway / 药学实践杂志

Objective To explore the effects of Humulus lupulus L. extract (HLE) and its mechanism on improving bone formation of Aβ-injured osteoblasts. Methods Osteoblasts isolated from 24 h-old Wistar rats were injured by Aβ1-42 oligomer and intervened with HLE. The proliferation, differentiation and bone mineralization of osteoblasts were determined by MTT assay, alkaline phosphatase (ALP) activity assay and alizarin red staining, respectively. The apoptosis of osteoblasts was detected by flow cytometer. The expression levels of bone formation related proteins, and proteins of Nrf2 and FoxO1 pathways were measured by Western blotting analysis. The intranuclear expression of FoxO1 protein was detected by immunofluorescence. Results HLE significantly improved the cell proliferation, ALP activity and bone mineralization, and inhibited the apoptosis of Aβ-injured osteoblasts. HLE also significantly promoted the expressions of collagen type Ι (COL-I) and osteopontin (OPN) in Aβ-injured osteoblasts. HLE notably activated the Nrf2 and FoxO1 signaling pathways in Aβ-injured osteoblasts by promoting the expressions of related proteins and maintained bone metabolism through relieving oxidative stress. Conclusion This study confirms that HLE can alleviate Aβ-injury to osteoblasts, and preliminarily clarifies the mechanism being related to antioxidation, which provides a new reference for the mechanism research and drugs development for anti-osteoporosis.

Clinical significance of classification and grading of ovarian serous tumors and its relationship with the expressions of p53 and Ki-67 proteins / 肿瘤研究与临床

Objective:To explore the clinical significance of classification and grading of ovarian serous tumors (OST) and the correlation of classification and grading with expressions of p53 and Ki-67 proteins, so as to provide a basis for accurate diagnosis and reasonable treatment of OST.Methods:A total of 100 paraffin-embedded ovarian tissues were collected from Haikou Affiliated Hospital of Central South University Xiangya School of Medicine from January 2012 to November 2017. The classification and grading of OST was based on the World Health Organization (WHO) ovarian tumor tissue classification, the work conference on borderline ovarian tumors which was held in August 2013 in Maryland, United States, and the two-level tissue classification system of the United States MD Anderson Cancer Center. The 100 cases of ovarian tissues included 10 cases of normal ovarian tissues (NOT), 12 cases of ovarian serous cystadenoma (OSA), 18 cases of ovarian serous borderline tumor (OSBT), 22 cases of low-grade serous carcinoma (LGSC), and 38 cases of high-grade serous carcinoma (HGSC). The expressions of p53 and Ki-67 proteins in paraffin-embedded tissues were detected by immunohistochemistry. The clinical characteristics of patients with different types of OST and their relationships with the expression of p53 protein and Ki-67 positive index were analyzed.Results:Among OSBT, LGSC and HGSC groups, the proportion of patients with onset age > 50 years old [38.9% (7/18), 45.5% (10/22), 73.7% (28/38)], poor differentiation [0 (0/18), 0 (0/22), 100.0% (38/38)], stage Ⅲ-Ⅳ [5.6% (1/18), 27.3% (6/22), 39.5% (15/38)] increased sequentially, and the differences were statistically significant (all P < 0.05). Among NOT, OSA, OSBT, LGSC and HGSC groups, there were significant differences in the positive rate of p53 protein [20.0% (2/10), 25.0% (3/12), 27.8% (5/18), 31.8% (7/22), 57.9% (22/38)] and Ki-67 positive index [(10.40±0.00)%, (31.49±6.53)%, (42.81±6.84)%, (74.29±6.54)%, (77.04±8.88)%] (all P < 0.05). In the patients with ovarian serous carcinoma (LGSC + HGSC), there was no significant difference in the positive rate of p53 protein and Ki-67 positive index between the onset age ≤ 50 years old and > 50 years old groups (both P > 0.05), but there were significant differences between the patients with different tissue differentiation grade, clinical stage and metastasis (all P < 0.05). There was significant difference in Ki-67 positive index among NOT, OSA, OSBT, LGSC and HGSC patients with positive expression of p53 protein ( P < 0.01). Conclusions:The classification and grading of OST is related to onset age, tissue differentiation and clinical stage, which can be used to guide treatment and judge prognosis. The positive rate of p53 protein and Ki-67 positive index increase with advancing grade of breast lesions, which may be related to the occurrence and development of OST.

Microcystic Stromal Tumor of Testicle: First Case Report and Literature Review / Journal of the Korean Cancer Association, 대한암학회지

Microcystic stromal tumor (MCST) is a rare subtype of sex cord-stromal neoplasm. Tumors from all 31 previously reported cases were located in the ovary. Herein, we present a unique case of a right-side testicular tumor in a 33-year-old Chinese male. The tumor is composed of predominantly lobulated cellular nodules separated by hyalinized fibrous stroma and they expressed CD10, β-catenin (nuclear), and cyclin D1. Molecular analysis identified a point mutation (c.110C>G) in exon 3 of CTNNB1. The histopathological features, immunohistochemistry profiles, and molecular analysis of this tumor were consistent with MCST of the ovary. Therefore, a diagnosis of MCST of the right testicle was determined. To the best of our knowledge, this is the first case of MCST occurring in the testicles. The study may provide new insights to the tumor biology of MCST and a better understanding of this rare entity.

Erdheim-Chester Disease with Emperipolesis: A Unique Case Involving the Heart / Journal of the Korean Cancer Association, 대한암학회지

Histiocytosis is an uncommon disease characterized by excessive accumulation of histiocytes. Here, we report a rare case of non-Langerhans-cell histiocytosis in a 51-year-old woman who presented with severe symptoms of pericardial effusion. Radiologic investigation also detected multiple bone (lower limbs, vertebrae, ribs, and ilium) lesions. Resected pericardium showed abundant mono- or multi-nucleated non-foamy histiocytes (CD68⁺/CD163⁺/S-100⁺/CD1α⁻/langerin⁻) in a fibroinflammatory background. The histiocytes demonstrated emperipolesis of lymphocytes, a hallmark feature of Rosai-Dorfman disease (RDD). However, molecular analysis revealed a BRAF V600E mutation of the proliferating histiocytes, highlighting the neoplastic features frequently observed in another non-Langerhans-cell histiocytosis known as Erdheim-Chester Disease (ECD). We consider this case to be a unique presentation of ECD harboring some RDD-like cells with emperipolesis, but not a case of RDD with a BRAF mutation concerning its clinical manifestation (involvement of the heart and bones) and neoplastic features.
