Lacrimal gland adenoid cystic carcinoma (LGACC) is the most common primary malignant epithelial tumor of the lacrimal gland and has the characteristics of high recurrence rate, neurotropic growth, and risk of distant metastasis. The clinical manifestation is mainly a mass in the lacrimal gland area with a poor specificity. The combination of MRI and CT is important in the diagnosis of LGACC, and PET/CT is of great value in determining the nature and metastasis of LGACC. Histopathological examination is the gold standard for diagnosis, and the type of histopathology is significant for predicting the prognosis of patients. At present, the most commonly used treatment for LGACC is surgical resection combined with postoperative local radiotherapy. However, the overall prognosis is poor after active treatment because the pathogenesis of LGACC remains unclear. This article will combine relevant literature and the author’s clinical experience to review the epidemiology, clinical manifestations, imaging examination, histopathological changes, treatment, and prognosis of LGACC. Results will contribute to improve the quality of diagnosis and treatment and the prognosis of patients. [ABSTRACT FROM AUTHOR]

Hibiscus mutabilis is native to China with a long cultivation history, and is an ancient garden tree species and medicinal plant. In this study, we selected three cultivars of H. mutabilis in a hybrid combination(H. mutabilis cv. Danbanbai, H. mutabilis cv. Jinqiusong, H. mutabilis cv. Mudanfen)to investigate evolutionary characteristics between the cultivars of H. mutabilis and its related species, and clarify the phylogenetic relationship between the cultivars of H. mutabilis and its related species, as well as explore the genetic model of chloroplast genome(cpDNA)of H. mutaibilis at the same time. We first sequenced the three cultivars of H. mutaibilis using Illumina NovaSeq. After assembly and annotation, three complete chloroplast genome sequences were obtained. The cpDNAs of the related species H. taiwanensis from our group, and H. syricus and H. rosa-sinensis from the gene bank. Then we carried out comparative analysis on composition and structure of cpDNAs of four species of Hibiscus and three cultivars of H. mutabilis, and completed its phylogenetic tree reconstruction. The results were as follows: (1)Total sizes of cpDNAs of H. mutabilis cv. Danbanbai, H. mutabilis cv. Jinqiusong, H. mutabilis cv. Mudanfen were 160 880, 160 879, 160 920 bp, respectively, and the total gene number was 130, including 85 protein-coding genes, eight ribosomal RNAs, and 37 transfer RNAs. (2) The comparative analyses showed that the cpDNAs of three cultivars of H. mutabilis and the related species H. taiwanensis were highly conserved, and the inverted repeat regions(IR)were all 26 300 bp; H. rosa-sinensis and H. syriacus shrank to at 25 745 and 25 598 bp, respectively.(3)The phylogenetic analysis revealed that the three cultivars were planted into a monophyletic branch, and then together with H. taiwanensis into a high support branch, indicating that H. mutabilis and H. taiwanensis had the closest relationship; Compared with H. syriacus and H. rosa-sinensis, H. mutabilis and H. taiwanensis were more closely related to H. hamabo, H. tiliaceum and H. canabinus.(4)Three cultivars of H. mutabilis could be distinguished by cpDNA sequence, the length of LSC/SSC of H. mutabilis cv. Danbanbai, H. mutabilis cv. Jinqiusong, H. mutabilis cv. Mudanfen were 89 355 bp/18 925 bp, 89 353 bp/18 926 bp, 89 400 bp/18 920 bp, respectively. And candidate molecular markers and DNA barcodes had been developed from repeat sequence and nucleotide diversity analyses, which could be used as a tool for cultivars identification.(5)The cpDNAs of H. mutabilis cv. Danbanbai and H. mutabilis cv. Jinqiusong showed a minimum difference and had the closest phylogenetic relationship. According to the relationship between their female and offspring, the maternal genetic characteristics of the cpDNAs of Hibiscus were proved. This study will help us to understand the evolutionary characteristics and phylogenetic relationship of cpDNAs of three cultivars of H. mutabilis and H. taiwanensis, and provide basic data on cpDNA for accurate identification of the cultivars of H. mutabilis and breeding of excellent cultivars.

Objective To investigate the effect of hepatitis B virus (HBV) infection on the activation of hepatic stellate cells (HSCs) and its mechanism of action. Methods A total of 30 plasma samples of chronic hepatitis B patients, 42 plasma samples of hepatitis B cirrhosis patients, 30 plasma samples of hepatocellular carcinoma patients, and 18 plasma samples of the individuals undergoing physical examination were collected from November 2020 to January 2021, and ELISA was used to measure the content of hepatitis B X protein (HBx), transforming growth factor-β1 (TGFβ1), dopamine beta-hydroxylase (DBH), and hydroxyproline (HYP) in plasma and conditioned medium. LO2 cells were used to establish a cell line with stable overexpression of HBx (LO2-HBx) and negative control cells (LO2-con), and a conditioned medium was prepared for LO2-HBx, LO2-Con, and LO2 cells (Mock), respectively; human HSC cell line LX-2 was incubated and divided into LX-2/LO2-HBx, LX-2/LO2-con, and LX-2/Mock groups, and CCK-8 assay was used to measure the change in cell proliferation. LX-2 cells were stimulated by rhTGFβ1, and the cells in the LX-2/LO2-HBx group were treated with a TGFβ1 receptor inhibitor. Quantitative real-time PCR and Western blot were used to measure the expression of HBx in LO2 cells and the expression of alpha-smooth muscle actin (α-SMA), collagen type Ⅰ alpha 1 (Col1A1), DBH, and TGFβ1 in the above LX-2 cells. An analysis of variance was used for comparison between multiple groups, and the Bonferroni method was used for further comparison; the t-test was used for comparison between two groups; the Pearson method was used for correlation analysis. Results LO2-HBx stably expressed HBx protein and showed an increase in the content of TGFβ1 in supernatant (F=324.701, P < 0.01). The co-cultured LX-2/LO2-HBx group had a significant change in cell morphology, with the presence of cell shrinkage, extended cytoplasmic process, and reduced lipid droplets, and compared with the LX-2/LO2-con group, the LX-2/LO2-HBx group had significant increases in proliferative activity (P < 0.05) and the mRNA and protein expression levels of α-SMA and Col1A1 (mRNA: F=144.712 and 76.680, both P < 0.01; protein: F=234.142 and 528.708, both P < 0.001). The LX-2/LO2-HBx group had significant increases in the content of TGFβ1 (F=29.382, P < 0.01) and DBH (F=42.662, P < 0.01). With the increase in the stimulating concentration of rhTGFβ1, there were significant increases in the expression of α-SMA (F=1 794.031, P < 0.01), Col1A1 (F=91.340, P < 0.01), and DBH (F=2 501.011, P < 0.01), which reached the peak values at the rhTGFβ1 concentration of 10 ng/ml, and after a TGFβ1 receptor inhibitor was added to the conditioned medium, the LO2-HBx group had significant reductions in the expression of DBH and Col1A1 compared with the control group (t=3.603 and 5.798, both P < 0.05). Compared with the healthy control group, the chronic hepatitis B, liver cirrhosis, and hepatocellular carcinoma groups had significant increases in the plasma levels of TGFβ1 (F=51.188, P < 0.001), HBx (F=39.227, P < 0.001), DBH (F=34.431, P < 0.001), and HYP (F=16.211, P < 0.001), and a positive correlation was observed between plasma HBx and TGFβ1, between TGFβ1 and DBH, and between HYP and DBH (r= 0.931, 0.863, and 0.765, all P < 0.001). Conclusion HBx protein can promote the secretion of TGFβ1 in LO2 cells, induce the proliferation and activation of LX-2 cells, promote the development of liver fibrosis, and upregulate the expression of TGFβ1 and DBH in LX-2 cells, and rhTGFβ1 stimulation can induce the activation of LX-2 cells and the upregulation of DBH expression.
