Based on the pathogenetic occurrence of the tumor,multinodular hepatocellular carcinoma can be classified into multicentric occurrence and intrahepatic metastasis.Different diagnostic strategies from genomics,transcriptomics and proteomics can be used to define the clonal origin of tumors and provide advisable method to cure the disease.Pathomorphological test wasgold standard in cancer diagnosis at one time.Currently,from the respect of molecular diagnosis,including HBV DNA intergration,p53 mutation,selective X chromosome inactivation,loss of heteozygosity of chromosomal DNA,mtDNA-Loop,transcriptional sequence,and comparative proteomics,we could accurately differentiate the clonal origin of tumors.Intrahepatic metastasis was demonstrated with a high early recurrence rate and low survival rate comparing to the multicentric occurrence from the review of the previous study.

Objective To investigate the expression of proliferating cell nuclear antigen (Ki67) in hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) tissue and its correlation with clinicopathological parameters of HBV related HCC. Methods HBV-related HCC patients (n=134) were divided according to Ki67 index (the percentage of Ki67-posi?tive cells) into Ki67 index<10%group (negative group, n=30) and Ki67 index≥10%group(positive group, n=104). The cor?relation of Ki67 index with age, gender, glypican 3 (GPC3), histological grade, BCLC (Barcelona Clinic liver cancer) staging, portal involvement, AFP (AFP), liver function related child-pugh classification data were calculated in both groups. Ki 67 in?dex is set according to the interval score to assess the relationship between Ki67 score and BCLC classification. Results (1) SP staining showed, Ki67 present a trend of increase from normal liver tissue to well-differentiated to medium differentiat?ed tissue to poorly differentiated tissues intensity. (2) In positive group, Ki67 index was correlated with BCLC staging, portal metastasis, histological grade, GPC3 and AFP (P<0.05);By contrast, in negative group, Ki67 index was not correlated with any clinical parameter (P>0.05). (3) Ki67 score increases with the progress of BCLC classification. Conclusion In Ki67 positive group, Ki67 index combined with GPC3, histological grade, BCLC staging, portal involvement, AFP and liver func?tion child-pugh classification can assess the severity of the patients with HCC, which is expected to become an important in?dicator for the HBV-related HCC early diagnosis.

To study the effect of total matrines and extracts from Periplaneta americana on negative endometrial cancer cell JEC of progesterone receptors. After detecting the effect of total matrine, extracts from P. americana and their combination on JEC cells' growth inhibition, cell cycle, P53 and c-erbB-2 gene protein expressions through MTT, flow cytometry instrument and Western blot method, the author found that, (1) MTT: total matrines and extracts from P. americana could inhibit the growth of JEC cell, with significant increase in the inhibitory effect in the combination group. (2) Flow cytometry instrument: the cell cycle at G0/G1 increased after the treatment with total matrines, the cell cycle at G2/M increased after the treatment with extracts from periplaneta americana, and the ratio of G0/G1 cell cycle in the combination group was significantly higher than the other groups, with inhibition in cell growth and statistical difference in inter-group comparison (P < 0.05). (3) Western blot: the expression level of P53 increased and c-erbB-2 decreased after the treatment with total matrines, extracts from P. americana and their combination on JEC cell, with statistical difference in inter-group comparison (P < 0.05). The above results suggested that total matrines, extracts from P. americana and their combination could induce cell cycle arrest and inhibit the growth of JEC cell by up-regulating P53 and down-regulating the c-erbB-2 level.

In Western countries, the mutation status of the BRCA1 and BRCA2 genes is commonly determined for genetic counseling among members of families with a history of breast or ovarian cancer, especially for women of the Ashkenazi Jewish ethnicity. Recent studies in the Cancer Genome Atlas project have demonstrated that BRCA2 mutation carriers are more responsive to platinum-based chemotherapy among high-grade serous ovarian cancer patients. Thus, in Western countries, the mutation status of BRCA1 and BRCA2 is recognized to have an important value with which to assess cancer risk and therapeutic response. However, very limited studies of BRCA1 and BRCA2 mutations and their implications for counseling and therapeutic prediction have been conducted in China. Therefore, a potentially important genetic test that is technically simple has not benefited Chinese women with an increased risk of breast or ovarian cancer. This article summarizes the current progress in the study of BRCA1/2 mutation in China and recommends an increased effort in applying advances in genetic testing to the clinical management of Chinese patients with ovarian cancer.

AlM: To compare the anterior segment measurements derived from optical low coherence reflectometer ( Lenstar LS900 ) and combined Scheimpflug - Placido disk topographer ( Sirius) .
METHODS: ln this study, we enrolled healthy myopic subjects 54 ( 87 eyes ) . The central corneal thickness (CCT), anterior chamber depth (ACD), flat keratometry ( FK) readings , steep keratometry ( SK ) readings and white to white ( WTW ) were measured by LS900 and Sirius. Evaluation and analysis were performed using paired t tests, the Pearson correlation, and Bland-Altman analyses.
RESULTS: The CCT and ACD measurements were significantly lower whereas FK, SK and WTW measurements were higher with LS900 (P<0. 001). Mean differences were -6. 11 ± 6. 32μm,-0. 09 ± 0. 07mm, 0. 18 ± 0. 25D, 0. 21 ± 0. 36D and 0. 25 ± 0. 39mm with statistical significant (P<0. 01). Pearson correlation analysis showed high correlation between the 2 devices for all measurements (P<0. 001). On Bland-Altman analysis, 95% limits of agreement for all measurements were 6. 26 to -18. 49μm; 0. 04 to 0. 22mm; 0. 68 to 0. 32D; 0. 92 to 0. 50D and 1. 00 to 0. 5mm.
CONCLUSlON: Anterior segment parameters evaluated with LS900 and Sirius systemare correlated well and achieve good agreement. However, there are significantly statistical differences which may be caused by the different measurement modes, so they may not be interchangeable use under certain clinical circumstances.

The Tongmai Yangxin pill (TMYX) has potential clinical effects on no-reflow (NR); however, the effective substances and mechanisms by which this occurs remain unclear. This study evaluates the cardioprotective effects and molecular mechanisms of TMYX against NR. We used a myocardial NR rat model (2 h after myocardial ischemia and 2 h after reperfusion) to confirm the effect and mechanism of action of TMYX in alleviating NR. In vitro studies in isolated coronary microvasculature of NR rats and in silico network pharmacology analyses were performed to reveal the underlying mechanisms of TMYX and determine the main components, targets, and pathways of TMYX, respectively. The experiment was approved by the Ethics Committee of Hunan University of Chinese Medicine (LLBH-202212160001). TMYX showed therapeutic effects on NR by improving cardiac structure and function, reducing NR, ischemic areas, and cardiomyocyte injury, and decreasing the content of cardiac troponin I (cTnI). Moreover, the mechanism of TMYX predicted by network pharmacology is related to the hypoxia inducible factor-1 (HIF-1), nuclear factor kappa-B (NF-κB), and tumor necrosis factor (TNF) signaling pathways. TMYX increased the expression of G protein-coupled estrogen receptor (GPER), phospho-extracellular signal-regulated kinase (p-ERK), and HIF-1α. In vitro, TMYX enhanced the diastolic function of coronary microvascular cells; however, this effect was inhibited by GPER inhibitor (G-15), eNOS inhibitor (L-NAME), and sGC inhibitor (ODQ). This study integrates pharmacology and experimental evaluation to reveal that TMYX activates HIF-1α/eNOS signaling pathway by upregulating GPER to relax coronary microvessels, thereby significantly alleviating NR.
